RESUMO - A condutividade elétrica da solução de embebição de sementes é um procedimento recomendado para avaliar o vigor de sementes, porém, ainda não se tem um procedimento padrão para diversas espécies. Objetivou-se determinar o tempo e a temperatura adequadamente combinados para o teste de condutividade elétrica em sementes de sorgo (Sorghum bicolor L.). A conditividade elétrica da água de embebição foi medida usando um condutivímetro, com temperatura na estufa encubadora BOD de 20, 25 e 30 °C em períodos de 2, 4, 8, 16, 20 e 24 horas usando 50 e 25 mL de água destilada. O experimento foi designado em um esquema fatorial de 3x6x2 e aleatoriamente agrupado, com cinco repetições de 50 sementes por amostra. Os resultados evidenciaram que o aumento do tempo de embebição das sementes e da temperatura causou um aumento nos valores de condutividade elétrica. A temperatura afetou significativamente os valores de condutividade elétrica e os melhores resultados foram obtidos a 25 e 30 °C. As sementes embebidas em 25 mL de água destilada apresentaram maiores valores de condutividade elétrica independentemente da temperatura para todos os períodos de tempo. Concluiu-se que a temperatura de 30 °C no período de embebição de 16 horas e volume de 25 mL de água é a combinação mais adequada para realizar o teste de condutividade elétrica em sementes de sorgo.Palavras-chave: Sorghum bicolor, germinação, vigor.METHODOLOGY FOR THE TEST OF ELECTRICAL CONDUCTIVITY IN GRAIN SORGHUM SEEDSABSTRACT - The electrical conductivity of the seed imbibing solution is a recommended method of evaluating seed vigour, but there is still no standard method for the different species. The aim of this study was to determine a suitably combined time and temperature for the test of electrical conductivity in sorghum seeds (Sorghum bicolor L.). The electrical conductivity of the imbibition water was measured using a conductivity meter, at temperatures in the BOD incubator of 20, 25 and 30 °C, and at periods of 2, 4, 8, 16, 20 and 24 hours, using 50 and 25 mL of distilled water. The experiment was designed as a 3x6x2 randomly grouped factorial scheme, with five replications of 50 seeds per sample. The results showed that increases in seed imbibition time and temperature caused an increase in the values of electrical conductivity. The temperature had a significant effect on the values of electrical conductivity, with the best results obtained at 25 and 30 °C. The seeds soaked in 25 mL of distilled water showed higher values for electrical conductivity independently of temperature for all periods. It was concluded that a temperature of 30 °C at an imbibition time of 16 hours, and volume of 25 mL of water is the most suitable combination to carry out the test of electrical conductivity on sorghum seeds.Keywords: Sorghum bicolor, germination, vigour.

Full textAbstract:
Background Radial artery occlusion is an infrequent complication of transradial catheterization. Assessment of radial artery occlusion is a critical aspect of clinical care, and it should be done with an additional test, commonly by a plethysmographic test (reverse Barbeau test) or ultrasound (Doppler), the last is the gold standard. The objective of this study was to evaluate the accuracy of the reverse Barbeau test in detecting radial artery occlusion after transradial catheterization. Methods A study carried out in two centers encompassing patients submitted to procedures by radial access. All patients received at least 5,000IU of heparin. Sheaths were immediately removed after the procedure, using a patent hemostasis protocol. Patency of the radial artery was verified by reverse Barbeau test and duplex Doppler evaluation within the first 24 hours. Results A total of 350 patients were enrolled, with a mean age of 61.7 (±9.7) years. Radial artery occlusion was verified after the procedure in 19 (5.4%) patients, using duplex Doppler scan. Application of reverse Barbeau test had the following results: 64.0% type A curve, 15.7% type B, 8.3% type C, and 12.0% type D (the last suggesting occlusion). With reverse Barbeau test, patients with confirmed occlusion by ultrasound evaluation, 21.1% would be missed by a false-negative test, and in the ones, without radial artery occlusion, 8.2% would be misdiagnosed as having it (sensibility 78.9%; specificity 91.8%). Conclusion Reverse Barbeau test has good accuracy to detect radial artery occlusion, and it is a good option for clinical day use, although using reverse Barbeau test results in the overestimation of radial artery occlusion.

AbstractBonding of fiber posts using self-adhesive resin cement to radicular dentin is controversial. The aim was to evaluate the effect of conditioning of polyacrylic acid on the longevity of bonding of self adhesive resin cement to dentin. Thirty six single rooted pre molars were divided into 3 groups (n=12) ARC: ScotchBond Multi Purpose + RelyX™ARC; U: RelyX™U200; PU: 11.5% Polyacrylic acid + RelyX™U200. After conditioning of the dentin, the resin cement and the post were inserted and light-activated for 60s (1200mw/cm2) and stored in distilled water (24h/37ºC). Two discs of 1 mm thickness were obtained from each root-third and tested in push-out (0.5mm/min) after 24 hours and 6 months. For statistical purposes, the data from the root thirds were grouped and the bond strength (in MPa) was analyzed using Two-Way Analysis of Variance and Tukey’s post-hoc test at 5%. The power of the test was calculated. The bonding of the U at 6 months was higher than PU at both times (p<0.001). There were no differences for time (p=0.153) or for the interaction of treatment x time (p=0.090). Adhesive fractures between the cement and dentin were prevalent. The power test was 0.97. The bonding of the RelyX™U200 was influenced by the dentin pre-treatment with poliacrylic acid and the bonding of all groups remained stable for 6 months.Keywords: Dental Cements. Dentin. Shear Strength.ResumoA adesão de pino de fibra de vidro com cimento resinoso autoadesivo à dentina é controversa.

Após condicionamento da dentina, o cimento resinoso e o pino de fibra de vidro foram inseridos, fotoativados por 60s (1200mw/cm2) e armazenados em água destilada (24h/37ºC). Dois discos de dentina de 1 mm de espessura foram obtidos de cada terço radicular e testados em push-out (0.5mm/min) após 24 houras e 6 meses. Para análise estatística, os dados dos terços radiculares foram agrupados e resistência adesiva (em MPa) analisada por Análise de Variância de dois fatores e teste de Tukey a 5%. O poder do teste foi calculado. A adesão de the U após 6 meses foi maior que a de PU nos dois períodos (p<0,001). Não houve diferença para o fator tempo (p=0,153) nem para a interação tratamento x tempo (p=0,090). Fraturas adesivas prevaleceram entre cimento e dentina. O poder do teste calculado foi de 0,97. A adesão do RelyX™U200 foi influenciada pelo pré-tratamento da dentina com ácido poliacrílico e a adesão de todos os grupos se manteve estável até 6 meses.Palavras-chave: Cimentos Dentários. Dentina.

OBJETIVO: O objetivo do trabalho foi analisar os efeitos de um novo programa de intervenção na coordenação motora grossa (CMG) de crianças entre os 05 e 10 anos, avaliadas pela bateria de testes KTK. MÉTODOS: O programa foi realizado em 73 estudantes, selecionados de maneira não probabilística objetiva, com idades entre 05 e 10 anos, de uma rede municipal de ensino da cidade de Curitiba/PR, Brasil, divididos em dois grupos: Grupo Controle (GC=35) e Grupo Intervenção (GI=38). A CMG foi avaliada antes e depois da intervenção por meio da bateria de testes KTK. O programa de intervenção consistiu em 12 semanas de atividades alicerçadas nas estruturas da Técnica de Motivação Orientada Para Maestria (TARGET), e no livro “Escola da Bola – Um ABC para Iniciantes nos Jogos Esportivos”. Os efeitos foram testados utilizando o Teste de Cohen e teste t (dependente e independente).RESULTADOS: Na testagem t dependente, diferenças estatisticamente significativas foram encontradas no GI, do primeiro para o segundo momento, em todos os testes (d≥0,80). O GI obteve uma melhora significativa ao longo das 12 semanas (p<0,05), enquanto no GC não houve diferenças estatisticamente significativas. Na testagem t independente, no momento pré-intervenção (1º Momento), foram encontradas diferenças significativas (p<0,05) nas quatro tarefas, favoravelmente ao GC. No momento pós-intervenção, diferenças estatisticamente expressivas não foram observadas entre o GI e GC. CONCLUSÃO: Conclui-se que um programa interventivo, com duração de 12 semanas, utilizando os jogos da “Escola da Bola” em conjunto com o “TARGET”, trazem melhorias significativas no desempenho coordenativo das crianças, entre 5 e 10 anos de idade.Analyses of the effects of an intervention program based on TARGET structure and “Escola da Bola” on the gross motor coordinationABSTRACT OBJECTIVE: The objectives of the work were to analyze the effects of a new intervention program on gross motor coordination (GMC) of 5 and 10 year old children, diagnosed by the KTK battery test. METHODS: The program was carried out in 73 students, selected in an objective non-probabilistic way, aged between 5 and 10 years, from a municipal education network in the city of Curitiba, Brazil, divided into two groups: Control Group (CG=35) and Intervention Group (IG=38). CMG was assessed before and after the intervention using the KTK test battery. The intervention program consisted in 12 weeks of activities based on the structures of the Mastery-Oriented Motivation Technique (TARGET), and the book “Escola da Bola – Um ABC para Iniciantes nos Jogos Esportivos”. The effects were tested using the Cohen test and t-test (dependent and independent). RESULTS: In the dependent t-test, statistically significant differences were found on the IG, from the first to the second moment, in all tests (d≥0.80). The IG achieved a significant improvement over the 12 weeks (p<0,05), while in the CG there were no statistically significant differences. In the independent t-test, in the pre-intervention moment (1st Moment), significant differences (p<0,05) were found on the four tasks, in favor of the CG. In the post-intervention moment, statistically significant differences were not observed between the IG and CG. CONCLUSION: It follows that an intervention program, lasting 12 weeks, using the games of “Escola da Bola” together with “TARGET”, brings significant improvements in children’s coordinative performance, between 5 and 10 years old.

O presente trabalho analisou os aspectos sanitários e produtivos das Unidades de Terminação (UT) suinícolas do Estado de Mato Grosso. Foram levantados dados oficiais junto ao Instituto de Defesa Agropecuária do Estado de Mato Grosso, referentes a 55 granjas de terminação, distribuídas em 18 municípios, no período de dezembro de 2005 a janeiro de 2006. As características foram descritas e analisadas pelo teste de correlação Spearman, segundo o número de animais por UT, aspectos produtivos, sistemas de proteção sanitária, controle de possíveis veiculadores de agentes patogênicos e manejo dos animais. A população suína cadastrada totalizou 74.650 animais, sendo que 44 (80,0%) UT encontravam-se na região do cerrado. Segundo o número de suínos 10,9%, 9,1%, 14,%, 18,2%, 21,8% e 25% possuíam de 1 a 10, 11 a 100, 101 a 500, 501 a 1.000, 1.001 a 2.000 e acima de 2.000 suínos, respectivamente. As granjas integradas totalizaram 63,6% sendo que 89,1% empregavam manejo intensivo. As analises de correlações positivas (P < 0,05) foram observadas em diversos tipos de granjas, apresentando relação com: assistência veterinária, sistemas all-in all- out, incineração de carcaças, vassoura de fogo, compostagem, edificações de alvenaria e madeira, consumo de ração própria e comercial, abastecimento de água de represa, rio ou córregos e controle de moscas. Mesmo observando diferentes índices de correlação, detectaram-se inúmeros déficits de manejo sanitário em diversos segmentos das UT, por isso, questões relativas à biosseguridade das granjas do Estado de Mato Grosso devem ser revistas para que, futuramente, possa ser ava-liado o grau de vulnerabilidade delas.

Full textAbstract:
Background: All-inside meniscal repairs are performed with increasing frequency because of the availability of newly developed devices. A comparison of their biomechanical characteristics may aid physicians in selecting a method of meniscal repair. Hypothesis: All-inside meniscal repairs will be superior to their inside-out controls in response to cyclic loading and load-to-failure testing. Study Design: Controlled laboratory study. Methods: Sixty-six bucket-handle tears in matched porcine menisci were repaired using the Ultra FasT-Fix, Meniscal Cinch, Ultrabraid No. 0, and FiberWire 2-0 sutures. Initial displacement, cyclic loading (100, 300, and 500 cycles), and load-to-failure testing were performed. The displacement, response to cyclic loading, and mode of failure were recorded. The stiffness was calculated. Results: The Meniscal Cinch demonstrated a significantly higher initial displacement than the other methods tested ( P = .04). No significant difference was found among the methods in response to cyclic loading. The inside-out FiberWire repair demonstrated the highest load to failure (120.8 ± 23.5 N) and was significantly higher than both the Meniscal Cinch (64.8 ± 24.1 N, P < .001) and the Ultra FasT-Fix (88.3 ± 14.3 N, P = .002). It was not significantly higher than the inside-out Ultrabraid suture repair (98.8 ± 29.2 N). The inside-out FiberWire repair had the highest stiffness (28.7 ± 7.8 N/mm). It was significantly higher than the Meniscal Cinch (18.0 ± 8.8 N/mm, P = .01). The most common mode of failure in all methods was suture failure. Conclusion: An inside-out suture repair affords surgeons the best overall biomechanical characteristics of the devices tested (initial displacement, response to cyclic loading, and load to failure). For an all-inside repair, the Ultra FasT-Fix reproduces the characteristics of its matched inside-out suture repair more closely than the Meniscal Cinch. Clinical Relevance: Inside-out sutures and all-inside devices have similar responses to cyclic loading.

Conduziu-se o experimento entre fevereiro e abril de 2012, no “Campo experimental Água Boa” pertencente à Embrapa-Roraima, em sistema de cultivo sobre palhada, sob irrigação por aspersão convencional. O esquema utilizado foi blocos casualizados dispondo os tratamentos em faixa, com parcelas subdivididas e cinco repetições. Testou-se quatro lâminas de irrigação com base na evapotranspiração de referência ETo de 30%, 60%, 90% e 120%, estabelecidas diariamente por meio do Tanque Classe A para o qual foi adotado o coeficiente do tanque (Kp) 0,75. As sub-parcelas foram compostas por três cultivares de feijão-caupi (BRS Guariba, BRS Novaera e BRS Pajeú) sendo avaliados: altura de plantas, massa seca da parte aérea e índice da área foliar, submetendo os dados à análise de variância com aplicação do Teste F (p<0,05). As médias das cultivares foram comparadas por meio do teste de Tukey e as médias das lâminas, por meio de regressão polinomial e do Teste t (p<0,05). Todas as variáveis foram diretamente proporcionais ao incremento das lâminas de irrigação. A cultivar BRS Pajeú apresentou efeito quadrático, com máxima eficiência na produção de massa seca da parte aérea com a lâmina de 106,84% da ETo (30 g de MSPA, com aplicação de 317,75 mm), e máximo índice de área foliar com 89,31% da ETo (IAF = 2,74, com aplicação de 265,62 mm).

The experiment was carried out from February to April 2012, at the Agua Boa Experimental Station, which belongs to Embrapa Roraima, under no till system and sprinkler irrigation. The experiment used a statistical, strip-split-plot, randomized block design with four treatments, three treatments in the subplots, and five replications. Four water depths (30%, 60%, 90% and 120% of the reference evapotranspiration – ETo) and three cowpea cultivars (BRS Guariba, BRS Novaera and BRS Pajeú) were tested. The irrigation levels were based on fractions of daily ETo, estimated with a Class A evaporation pan, installed near the experimental area, adopting the pan coefficient (Kt) 0.75. The evaluated parameters were plant height, shoot dry mass and leaf area index. The data were submitted to analysis of variance with the F-test (p<0.05). The means for the cultivars were compared by Tukey’s test, and the means for irrigation water depths, by polynomial regression and by the T-test (p<0.05). All the analyzed parameters were directly proportional to the increase of the irrigation water depths. The cultivar BRS Pajeú showed a quadratic effect, with maximum efficiency in shoot dry matter production at a water depth of 106.84% ETo (SDM =30 g, with317.75 mm), and maximum leaf area index with 89.31% ETo (LAI = 2.74, with265.62 mm).

Abstract RFC 5180, the IPv6 update of RFC 2544, declared IPv6 transition technologies out of its scope. RFC 8219 defined a benchmarking methodology for IPv6 transition technologies including stateless NAT64 (more properly called SIIT) in the category of single translation solutions. Whereas several research papers have dealt with the performance of different stateful NAT64 implementations, none of them used RFC 8219 compliant measurements or addressed stateless NAT64 implementations. In this paper, we show, how stateless NAT64 implementations can be benchmarked carrying out the most important tests recommended by RFC 8219 without a special purpose NAT64 Tester, using simply an RFC 2544/RFC 5180 compliant legacy Tester. We carry out benchmarking measurements to examine the performance of three free software NAT64 implementations, namely: Jool, TAYGA and map646. All the details of our measurements are disclosed and their results are presented in the paper.

Previous issue date: 2014-07-31<br>Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>Introduction: Critical Power (CP) is the maximum rate can be maintained in a stable metabolic state muscle work. In the search for a test associated with less error and greater practical application, a series of studies investigating the validity of a single maximal test "all-out" to determine the PC. This test was designed with the assumption that, by inducing the depletion of anaerobic reservations as early as possible, the aerobic system predominantly assume the replenishment of ATP and consequently the amount of work done in this situation will be the next PC. Thus this study aims to explore the impact of hypoxia (FiO2 = 0,13), in determining the PC by 3-MT test. Methods: 8 healthy university students were evaluated (7 men and 1 woman). Incremental ramp test for determination of the maximal and submaximal parameters as well as the braking factor (power +50% Δ /pacing2 ) test three minutes to determine the maximum EP and W` in normoxia and hypoxia (Fi O2 = 0.13) conditions, constant load tests at 100% of EP determined in three minutes maximum. Student t test for the measurements between tests. Results: The main hypothesis of the study was not accepted since the addition of hypoxia did not cause enough stress to the point of changing the anaerobic contribution and interfere with the determination of EP (3-MTHYP = 213±43W, 3-MTNOR = 217±49 Wp = 0.35). There was no significant difference during the constant load tests at 100% of EP (EP 3-MTHYP = 23.95±8 min, EP-3 MTNOR = 19.41±10 min p = 0.36). Conclusion: Adding hypoxia (Fi O2 = 0.13) was not able to change the energy contribution to the point of changing the parameter EP aerobic and anaerobic W `, highlighting the robustness of the model against this intervention. Still, the responses associated with RPE during constant-load test are close to those encountered during constant load tests on PC. Further investigations with different levels of hypoxia are necessary for more conclusive answers.<br>Introdução: Potência crítica (PC) representa a máxima taxa de trabalho muscular possível de ser mantida em um estado estável metabólico. Na busca por um teste com menor erro associado e maior aplicação prática, uma série de trabalhos vem investigando a validade de um único teste máximo all-out para determinar a PC. Este teste foi concebido com o pressuposto de que, induzindo o esgotamento das reservas anaeróbias o quanto antes possível, o sistema aeróbio assumiria predominantemente a reposição de ATP e consequentemente a carga de trabalho realizada nessa situação será próxima a PC. Assim este estudo, tem como objetivo explorar o impacto da hipóxia (i.e. FiO2 0.13), na determinação da PC pelo teste máximo de três minutos (3-MT). Métodos: Oito universitários saudáveis foram avaliados (7 homens e 1 mulher). Teste incremental de rampa foi utilizado para determinação dos parâmetros máximos e submáximo bem como do fator de frenagem (potencia+50%∆ / cadendia2). Teste de 3-MT para determinação do EP e W` nas condições normoxia e hipóxia (Fi O2=0,13). Testes de carga constante a 100% dos EP foram utilizados para verificação das respostas fisiológicas. O teste t de student foi utilizado para as aferições entre os testes. Resultados: A hipótese principal do estudo não foi aceita, uma vez que a adição de hipóxia não gerou estresse suficiente ao ponto de alterar a contribuição anaeróbia e interferir na determinação do EP (3-MTHYP = 213±43W, 3-MTNOR = 217±49W p=0,35) . Também não houve diferença significativa durante os testes de carga constante a 100% dos EP determinados (EP 3-MTHYP = 23,95±8 min., EP 3-MTnor = 19,41±10 min. p= 0,36). Conclusão: A adição de hipóxia (Fi O2=0,13) não foi capaz de alterar a contribuição energética a ponto de alterar o parâmetro aeróbio EP, e anaeróbio W`, destacando a robustez do modelo frente a essa intervenção. Ainda, as respostas associadas ao EP durante o teste de carga constante estão próximas aquelas encontradas durante testes de carga constante na PC. Futuras investigações com diferentes níveis de hipóxia são necessárias para obter respostas mais conclusivas.

Previous issue date: 2011-02-23<br>Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>To date, sports scientists have still sought for noninvasive methods to determine the intensities corresponding to physiological transition threshold. The critical velocity (CV) model has been extensively studied in many exercises modes, however to determine CV is necessary to perform several predicting trials. To overcome this difficulty, it has been proposed a single test for determining the Critical Power (CP) which has shown to be reliable, correlate and similar to CP determined in cycle ergometer, remaining the need to seek similar evidences during running testing. The main objective of this study was to verify the validity of a single all-out 3 minutes running test (T3) for VC determination (V3min). Eight volunteers were submitted in different days to an incremental treadmill running test to determine VO2máx, the intensity corresponding to VO2máx (iVO2máx) and intensity corresponding to the first and second ventilatory threshold (VT1 and VT2, respectively), three T3 (familiarization, test and retest) to determine V3min, distance traveled (D3min) and peak speed (PV3min) measured by manual timing and VGPS, DGPS and PVGPS measured by a GPS device. Three maximal performances (in random order) on the distances of 800m, 1600m and 2400m were utilized to determine VC through distance/time model. The V3min was significantly higher (6.7%), but highly correlated (r = 0.88) with VC. ANOVA repeated measures showed high intraclasse correlation coefficient (ICC: 0.96; 0.87 and 0.96 to D3min, PV3min and V3min, respectively) and low typical errors of estimate indicating that the T3 presents a good reproducibility and the familiarization test might be discarded. The GPS device seems to be accurate and reliable for measuring speeds in the end of testing, however no confidence date seem to be measure for PV3min and DGPS. We conclude that the T3 showed to be highly reliable and correlate to VC, which can be used to estimate aerobic capacity. However, we suggest caution to use the T3 test for VC determination.<br>Diante da necessidade de se buscar métodos não invasivos para determinação de limiares de transição fisiológicas o modelo convencional de determinação da velocidade crítica (VC) surge, trazendo consigo uma quantidade elevada de testes que preferencialmente deveriam ser realizados em dias diferentes. O modelo de teste único proposto para determinação da Potência Crítica (PC) parece resolver esse problema, restando a necessidade de se buscar indícios semelhantes em testes de corrida. Assim, o principal objetivo do estudo é verificar se um teste único de corrida em máxima velocidade durante 3 minutos (T3) é válido para determinação da VC de indivíduos fisicamente ativos. Oito indivíduos ativos foram submetidos, em dias diferentes, a um teste incremental em esteira rolante para determinação do consumo máximo de oxigênio (VO2máx), da intensidade do VO2máx (iVO2máx) e da intensidade do primeiro e do segundo limiar ventilatório (VT1 e VT2, respectivamente), três T3 (familiarização, teste e reteste) em pista de 200m para determinação da V3min, da distância percorrida (D3min) e de pico de velocidade (PV3min) (cronometragem manual) e VGPS, DGPS e PVGPS (monitoramento via GPS); e por último três testes máximos de campo em distâncias fixadas em 800m, 1600m e 2400m (em ordem aleatória) para determinação da VC através do modelo trabalho/tempo. A V3min foi identificada 6,7% acima, mas significativamente correlacionada com a VC (r = 0,88). O resultado de ANOVA de medidas repetidas bem como altos coeficiente de correlação intraclasse (ICC: 0,96; 0,87 e 0,96 para D3min, PV3min e V3min, respectivamente), e baixos erros típico de medida indicam que o T3 tem boa reprodutibilidade e indica a possibilidade de descarte da familiarização para o T3. O dispositivo de GPS parece ser confiável para medida da velocidade nos instantes finais do teste, deixando dúvidas quanto a sua confiabilidade em medir o PVGPS e a DGPS. Podemos concluir, portanto, que o T3 é um teste reprodutivo e bem relacionado à VC, podendo ser usado como índice de capacidade aeróbia. No entanto, sugerimos cautela na utilização do teste como meio de determinar a VC.

Master of Science<br>Department of Kinesiology<br>Thomas J. Barstow<br>Purpose: To determine if a single test is accurate in determining the parameters of the velocity: time-to-fatigue relationship, i.e., critical velocity (CV) and a finite distance that can be covered above CV (D`). Methods: Ten healthy subjects completed an incremental test to volitional exhaustion followed by four constant-velocity runs on a treadmill for the determination of CV and D`, as well as an all-out 3-minute test on a track for the determination of end-test velocity (EV) and the distance above end-test velocity (DEV). Eight of the eleven subjects completed a second 3-minute test and one run each at (+) and (-) 95% confidence interval velocities of CV determined from the 1/time model. Results: The group mean 1/time model CV (12.8 ± 2.5 km·h[superscript]-1) was significantly greater than the velocity-time model CV (12.3 ± 2.4 km·h[superscript]-1; P < 0.05), while the velocity-time model W` (285 ± 106 m) was greater than the 1/time model W` (220 ± 112 m; P < 0.05). EV (13.0 ± 2.7 km·h[superscript]-1) and DEV (151 ± 45 m) were not significantly different than the 1/time model CV and W`, respectively. EV was greater than the velocity-time model CV (P < 0.05), while the DEV was significantly less than the velocity-time model W` (P = 0.002). No difference was found for group mean EV or DEV between the two 3-minute tests (P > 0.05), which demonstrated a reliability coefficient of 0.85 for EV and 0.32 for DEV. For the CV (-) 95% run, all subjects reached a steady-state in VO[subscript]2, and completed 900 s of exercise. However, for the CV (+) 95% run, VO[subscript]2 never reached a steady-state, but increased until termination of exercise at 643 ± 213 s with a VO[subscript]2peak close to but significantly lower than VO[subscript]2max (P < 0.05). Conclusion: CV can be accurately determined using a single 3-minute test, while W` is underestimated with this protocol.

The hyperbolic relationship between power output and endurance time can be measured using all-out exercise. The aims of this thesis were to (i) assess whether the all-out test could be used under novel testing protocols to provide valid power-duration (P-D) parameter estimates; and (ii) attempt to elucidate the likely physiological composition of the P-D curvature constant. All-out tests were initiated from moderate-(M), heavy-(H) and severe-(S2 & S4) intensity ‘baselines’ (chapter 4). The work performed above end power (WEP) was not different to control under M or H conditions but was significantly, predictably reduced under the S2 & S4 conditions (control: 16.3 ± 2.2; M: 17.2 ± 2.4; H: 15.6 ± 2.3 kJ, P > 0.05; S2: 11.5 ± 2.5; S4: 8.9 ± 2.2 kJ, P < 0.05). The 3-min all-out test end power (EP) parameter was unaffected. Muscle glycogen may form part of the WEP. Type I (T1) and type II (T2) muscle fibres were depleted of their glycogen content prior to the all-out test (chapter 5). EP and WEP were unaffected by either T1 or T2 glycogen depletion. The all-out tests was conducted under hypoxic conditions alongside the criterion assessment of the P-D relationship (chapter 6). Normobaric moderate hypoxia caused a reduction in CP (control: 175 ± 25; hypoxia: 132 ± 17 W, P < 0.001) without affecting W′ (control: 13.2 ± 2.2; hypoxia: 12.3 ± 2.7 kJ, P > 0.05). The 3-min all-out test provided EP and WEP estimates, which did not differ to CP and W′ (control: EP 172 ± 30 W, WEP 12.0 ± 2.6 kJ; hypoxia EP 134 ± 23 W, WEP 12.5 ± 1.4 kJ, P > 0.05) providing the ergometer resistance was adjusted for the hypoxic conditions. Furthermore, a significant negative relationship was observed between %∆ ( O2peak – CP) and %∆W′ (r = -0.83, P < 0.001); thus, W′ may represent the relative ‘size’ of the severe-intensity domain. The all-out test was used to track training-induced changes in P-D parameters in response to 6-weeks of sprint or endurance training (chapter 7). EP & WEP were differently altered compared to CP and W′ following sprint training (CP 12 ± 9; EP -0 ± 9 % change; W′ -5 ± 25; WEP 11 ± 15 % change). The all-out test reliably tracked changes in CP and W′ following endurance training. In conclusion, the all-out test provides reliable EP and WEP values. Its validity is acceptable, but is perhaps affected by exercise training that is specific to the execution of the test. The W′ appears to be determined, to a large extent, by the relative size of the severe-intensity domain.

Full textAbstract:
This study examined whether the critical power (CP) and anaerobic work capacity (AWC) estimates from the CP 3-min all-out (CP3min) test were affected by the percentage of body weight used to set the resistance on a Monark cycle ergometer. Twenty-one subjects (11 women and 10 men) were placed into one of three groups (n=7) based on activity level; recreationally trained (REC), aerobic and anaerobic sport (SPORT), and endurance trained (END). The CP3min test was conducted at 4.5% of body weight (CP4.5%) and at a resistance setting based on group activity level (CPACT; REC = 3%, SPORT = 4%, and END = 5% of body weight). There were no differences between the CP4.5% or CPACT estimates in any of the three training groups. The AWC3% estimates were significantly lower than the AWC4.5% for the REC group, but there were no differences in the AWC4.5% and AWCACT for the SPORT or END groups.The principal finding of this study was that a resistance of 4.5% of body weight for CP3-min test may be used to estimate CP and AWC, without regard to the training status of the subjects.

碩士<br>國立臺灣師範大學<br>體育學系<br>100<br>Purpose: To investigate the effect of β-alanine supplement on the aerobic and anaerobic performance in elite athletes. Methods: Twenty-four athletes were recruited and randomly assigned to the β-alanine (6.4 g•d-1) or placebo (6.4 g•d-1 of cellulose) group. Before and after a 4 weeks supplement, participants performed the incremental cycling test and 3-min all-out cycling test to determine the effects of β-alanine on the physiological responses and performance, i.e., maximal oxygen uptake (VO2max) and ventilatory threshold (VT), peak oxygen uptake (VO2peak), end test power (EP), and work done above the EP (WEP). The blood samples were obtained during the 3-min all-out cycling test to measure the blood lactate and pH concentrations. Results: No significant differences were found on the all physiological variables or performance at pre- or post-supplementation between two groups. In the β-alanine group, no significant differences were found on the VO2max (pre vs. post, 55.8 ± 6.8 vs. 56.6 ± 5.5 ml•min-1•kg-1), VT (pre vs. post, 34.1 ± 3.7 vs. 35.5 ± 4.8 ml•min-1•kg-1), VO2peak (pre vs. post, 59.3 ± 7.2 vs. 57.7 ± 7.1 ml•min-1•kg-1), EP (pre vs. post, 257.8 ± 25.0 vs. 258.6 ± 30.7 W) and WEP (pre vs. post, 10.0 ± 3.4 vs. 10.5 ± 2.0 kJ) after supplementation. However, β-alanine supplementation significantly decreased blood lactate (pre vs. post, 11.0 ± 2.8 vs. 9.3 ± 2.0 mmol•L-1) and pH levels (pre vs. post, 7.17 ± 0.06 vs. 7.12 ± 0.05). There were no significant differences on the all physiological variables or performance in the placebo group between pre- and post-supplementation. Conclusion: β-alanine supplement might not improve the aerobic and anaerobic performance, but reduce the metabolic stress during 3-min all-out test in elite athletes.

Since most drivers still lack vehicle operating skills, knowledge of regulations, defensive driving skills and driving ethics, they do not dare to drive on the road after receiving their driver license. Traffic authorities consider changing the driving test system, adding actual road test to improve driving safety and resilience.
This study first reviews the existing inadequacy with driver license test, and then reviews both the domestic and oversea test system and the difficulty with road test piloting program and the reaction plan. The study also analyzes the feasibility of outsourcing, given that there is a manpower shortage with the road authority, and researches and formulates the challenges and the outsourcing process. Finally, the study provides the following findings and recommendations to be used as reference by government agencies in promoting the policies.
1.The admission practice of driving schools should be changed into two stages to fully implement the learning and practice of driving on the road.
2.Retain the coaching and the testing in simulated environment at driving schools to enhance the function of learning in driving.
3.It is advised to establish or seek collaboration with third-party independent certification agencies.
4.Recruit and select road test staff and invigilators and build their profile database.
5.The pay of invigilators and the rental fee for cars used in road tests are to be paid for by the test fee.
6.Amend regulations or special chapters related to road test outsourcing and prepare legal supporting measures.
7.Provisional licenses should be positioned in terms of functionality to reach the system balance principle for road test network.
8.Discipline management should be enforced. Test training staff should not be the examiner for the students from the same driving school to prevent any illegal activities.
9.Third-generation highway supervision information system should be modified accordingly to facilitate work dispatching.

Full textAbstract:
Chapter 75 laid out the basic principles that govern pulmonary gas exchange, a step necessary for the appropriate application and interpretation of common clinical tests of gas exchange. The present chapter discusses the several common tests and indices used to analyse and quantify gas exchange abnormalities in critically-ill patients. There is special emphasis on inherent limitations of each technique, as well as on ways to minimize technical and experimental errors when the necessary measurements are made. Limitations and errors are considered to be of major clinical importance because, while the measurements and indices themselves are easy to obtain, and have been in routine use for many years, serious errors of interpretation can occur if the limitations and common errors are not appreciated and allowed for. In particular, it is pointed out that factors external to the lungs can dramatically change arterial oxygenation in the critically-ill patient. This means that not all changes in gas exchange reflect changes in lung pathology. It is not uncommon for arterial PO2 to change without change in lung disease severity when external factors such as metabolic rate, cardiac output, and blood temperature change.

Since the early 1990s, at least forty-five initiatives have been mounted to improve the environmental and social performance of the mining industry. Many changes in the formal legal and regulatory systems have also been introduced. However, no systematic approach has been adopted to test whether this effort is making a difference. Without such monitoring of success, the tension between companies, communities, and governments regarding the role of mining in society will continue. This chapter makes the case for using ‘contribution analysis’ to fill this gap, a systematic means to assess and track mining’s contribution to human and ecosystem well-being over the full project and product life cycles. This is a higher test than current practice. It brings out a fuller picture of the positives and negatives of natural resources and their management, provides greater opportunity for the perspectives of all interests to be heard, and is fairer.

It also examines the implications of trade battles for democratic practices and movement mobilization. It describes how NAFTA has become a litmus test for candidates, and how opposition to NAFTA and to the loss of jobs to foreign countries may have impacted the 2016 presidential election. Although too many variables are in play to determine all the effects of NAFTA, the chapter describes some of those effects on jobs, manufacturing, and inequality.

Was it communism or socialism that succumbed in 1989? Was communism dead in 1989, when the ‘Sinatra Doctrine’ (‘each does it his own way’) replaced the Brezhnev Doctrine in East Central Europe? Or did the patient agonise until the official dismemberment of the Soviet Union in 1991? Twenty-seven countries share a communist past in Europe and Asia. Of the surviving five, not all would pass the ‘Leninist test’. Which legacies affect post-communist systems has been an issue under debate since shortly after the fall of the Old Regimes. Claus Offe pointed out that post-communist regimes are faced with a ‘dilemma of simultaneity’, amounting to a ‘triple transition’: the process of having to cope concomitantly with unconsolidated borders, democratisation, and property redistribution. While other authors have often wondered which legacies ‘count’ in post-communism (those of communism itself or the ante-communist heritage), it is Herbert Kitschelt's merit to have pointed out that the modes of communist rule have been in turn influenced by historical antecedents.

Full textAbstract:
Chapter 9 describes the food stamp program as inseparable from the romantic certainties that gave rise to the Personal Responsibility and Work Opportunities Reconciliation Act of 1996 (PRWORA). It focuses on Temporary Assistance for Needy Families (TANF). The characteristics of food stamp recipients and welfare recipients generally and the performance of welfare programs—objective social need and response—are less germane to the American people than their beliefs in virtue. Those beliefs are sustained by faith in an imagined tradition more than by social reality or even the effects that those beliefs have on the conditions of need. Food stamp benefits, taken together with all means-tested welfare programs, are inadequate to routinely raise recipients out of poverty. Serious deprivation remains widespread. Rather than relieve poverty, these public welfare programs ceremonialize the tenets of policy romanticism.

Full textAbstract:
According to Adams’ thesis the probability of a conditional is the conditional probability of the consequent given the antecedent. According to Stalnaker semantics, a conditional is true at a world just in case its consequent is true at all closest antecedent worlds to the original world. The chapter argues that Adams’ thesis and Stalnaker semantics are ways of cashing out the same ‘Ramsey test’ idea. Unfortunately, a well-known class of triviality theorems shows that Adams’ thesis and Stalnaker semantics are incompatible. Stefan Kaufmann has proposed (for reasons largely independent of the triviality theorems) a revised version of Adams’ thesis, which the chapter calls Kaufmann’s thesis. The chapter proves that combining Kaufmann’s thesis with Stalnaker semantics leads to ‘local triviality’ results, which seem just as absurd as the original triviality results for Adams’ thesis.

Full textAbstract:
This chapter reviews Fodor’s contribution to the epic Chomsky-Piaget Royaumont debate. The issue that was under discussion was a familiar one, namely, what psychological processes underlie concept learning. Piaget thought concept learning involved the formation and confirmation of hypotheses that a learner generates through the construction and organization of stimuli gathered from the environment, and modifying them when they proved to be inconsistent. However, Fodor pointed out a fundamental flaw in this theory: it is silent about the origin of the concepts used in generating the hypotheses. Fodor argued that in order for these hypotheses to be tested, let alone generated, they needed to have been readily available to the learner, suggesting that all primitive concepts are innate, and that concept acquisition relies on the process of triggering these concepts that are innately available to the learner, and not through construction by means of progressive guesses and trial-and-error.

AbstractThe need to characterise in-service damage in composite structures is increasingly becoming important as composites find higher utilisation in wind turbines, aerospace, automotive, marine, among others. This paper investigates the feasibility of simplifying the conventional acousto-ultrasonic technique set-up for quick and economic one-sided in-service inspection of composite structures. Acousto-ultrasonic technique refers to the approach of using ultrasonic transducer for local excitation while sensing the material response with an acoustic emission sensor. However, this involves transducers with several auxiliaries. The approach proposed herewith, referred to as vibro-acoustic testing, involves a low level of vibration impact excitation and acoustic emission sensing for damage characterisation. To test the robustness of this approach, first, a quasi-static test was carried out to impute low-velocity impact damage on three groups of test samples with different ply stacking sequences. Next, the vibro-acoustic testing was performed on all test samples with the acoustic emission response for the samples acquired. Using the acoustic emission test sample response for all groups, the stress wave factor was determined using the peak voltage stress wave factor method. The stress wave factor results showed an inverse correlation between the level of impact damage and stress wave factor across all the test sample groups. This corresponds with what has been reported in literature for acousto-ultrasonic technique; thus demonstrating the robustness of the proposed vibro-acoustic set-up.

Historically these have been prose documents, with all the problems that entails, but research over the last ten years has developed rigorous and executable-as-test-oracle specifications of mainstream architecture instruction sets and “user-mode” concurrency, clarifying architectures and bringing them into the scope of programming-language semantics and verification. However, the system semantics, of instruction-fetch and cache maintenance, exceptions and interrupts, and address translation, remains obscure, leaving us without a solid foundation for verification of security-critical systems software.In this paper we establish a robust model for one aspect of system semantics: instruction fetch and cache maintenance for ARMv8-A. Systems code relies on executing instructions that were written by data writes, e.g. in program loading, dynamic linking, JIT compilation, debugging, and OS configuration, but hardware implementations are often highly optimised, e.g. with instruction caches, linefill buffers, out-of-order fetching, branch prediction, and instruction prefetching, which can affect programmer-observable behaviour. It is essential, both for programming and verification, to abstract from such microarchitectural details as much as possible, but no more. We explore the key architecture design questions with a series of examples, discussed in detail with senior Arm staff; capture the architectural intent in operational and axiomatic semantic models, extending previous work on “user-mode” concurrency; make these models executable as test oracles for small examples; and experimentally validate them against hardware behaviour (finding a bug in one hardware device). We thereby bring these subtle issues into the mathematical domain, clarifying the architecture and enabling future work on system software verification.

AbstractMutual trust is the basis on which the Member States’ judiciaries are expected to deal with each other in the European Union. By constitutionalizing the principle of mutual trust, the CJEU has introduced an axiological addition to the basic structure of the European Union. From a Union which concentrated on the vertical relationships between each Member State and the central Union’s institutions, the Union has turned out to be additionally preoccupied with the horizontal relationships among the Member States, which are based on what might be called a doctrine of Horizontal Solange.According to the principle of mutual trust, each Member State must presume that all other Member States are in compliance with EU law, in particular promote its values and respect European fundamental rights. This presumption, however, can be rebutted in exceptional circumstances. These exceptional circumstances are based on a two-prong test: first, the violation of the values or the fundamental rights must amount to a systemic deficiency; second, there is a need for an assessment whether the individual concerned will be the victim of this systemic deficiency.This contribution critically analyses these exceptional circumstances. Regarding the first prong, it is argued that the existence of systemic deficiencies should ideally be established by the CJEU via preliminary ruling references or via direct infringement proceedings. Alternatively, such systemic deficiencies may also be established by domestic courts in a host Member State. Regarding the second prong, it is argued that the individual test is redundant in cases where the systemic deficiency imposes challenges to the existing legal order of the Member State in question. Finally, it is argued that the suspension of mutual trust can serve as a decentralized instrument for protecting the European rule of law by pressuring the violating state to restore the rule of law.

AbstractOne of the factors that will affect the livability of cities and the overall citizens’ quality of life in the future is certainly climate change. Urban areas will play a fundamental role in the commitment against climate change and will have to develop appropriate adaptation actions, in accordance with the European Strategy against climate change, including the planning and implementation of Green Infrastructures (GIs). They produce various environmental and social benefits in the urban context. Various studies have shown that citizenship involvement at all levels is necessary for the evaluation of the sharing of the proposed projects. The research proposes an innovative methodological model to support administrations in the strategic planning choice of GIs according to a shared and circular approach. To perform a multi-layer assessment, the multi-criteria evaluation will be combined with the circular evaluation model called Green City Circle. The evaluation is set up as a circular process, followed by a first investigative phase, followed by a proactive phase of solutions and an implementation phase up to a final stage of evaluation of the results and strategies for long-term sustainability. The study was carried out in the city of Catania to test a planning and management tool for GIs envisaged by the administration as win–win climate adaptation measures.

Full textAbstract:
The focus of this chapter is toward the factors needing attention while conducting the tests of performance. Chapters 5 and 6 discuss in detail the test plan as well as the test scripts required for conducting the performance tests. The successful execution of PT calls for coordination of a complex set of activities such as management of personnel, scheduling the tests at an appropriate time, configuring tools for various performance parameters, verification of application readiness for the test, and, above all, management of multiple test runs versus cost of resources. Conducting the tests may spread over a number of days, and it may also warrant customization of the operating system. The team responsible for carrying out the tests must be well aware of these factors. Typical test execution (see Test execution, 2004) phases are shown in Figure 7.1. Each phase must be planned carefully. If these phases are followed in sequence, the probability of test execution errors could be reduced. The main reason behind introducing these phases is to reduce the cost. To illustrate, if we directly run tests without passing through initial phases like elaboration test (say) and an error creeps in later, it will result in unnecessary investment of effort on test runs, which is very expensive. Specialized skills are required to run tests. Sometimes, the test environment (including tools) has to be taken on hire during the test runs. All these involve effort and time, which will go to waste if the tests are not executed properly. Each phase is explained in Figure 7.1.

Full textAbstract:
As part of a data mining competition, a training and test set of laboratory test data about patients with and without surgical site infection (SSI) were provided. The task was to develop predictive models with training set and identify patients with SSI in the no label test set. Lab test results are vital resources that guide healthcare providers make decisions about all aspects of surgical patient management. Many machine learning models were developed after pre-processing and imputing the lab tests data and only the top performing methods are discussed. Overall, RANDOM FOREST algorithms performed better than Support Vector Machine and Logistic Regression. Using a set of 74 lab tests, with RF, there were only 4 false positives in the training set and predicted 35 out of 50 SSI patients in the test set (Accuracy 0.86, Sensitivity 0.68, and Specificity 0.91). Optimal ways to address healthcare data quality concerns and imputation methods as well as newer generalizable algorithms need to be explored further to decipher new associations and knowledge among laboratory biomarkers and SSI.

Full textAbstract:
We describe a model-based construction of an online tester for black-box testing. Contemporary model-based online test generators focusing mainly on computationally cheap but far from optimal planning strategies cover just a fraction of the wide spectrum of test control strategies. Typical examples of those used are simple random choice and anti-ant. Exhaustive planning during online testing of nondeterministic systems looks out of reach because of the low scalability of the methods in regard to the model size. The reactive planning tester (RPT) studied in this chapter is targeted to fill the gap between these two extremes. The key idea of RPT lies in offline static analysis of the IUT (implementation under test) model to prepare the data and constraints for efficient online reactive planning. The external behavior of the IUT is modelled as an output observable nondeterministic EFSM (extended finite state machine) with the assumption that all the transition paths are feasible. A test purpose is attributed to the transitions of the IUT model by a set of Boolean variables called traps that are used to measure the progress of the test run. We present a way to construct a tester that at runtime selects a suboptimal test path from trap to trap by finding the shortest path that covers unvisited traps within planning horizon. The principles of reactive planning are implemented in the form of the decision rules of selecting the shortest paths at runtime. Based on an industrial scale case study, namely the city lighting system controller, we demonstrate the practical use of the RPT for systems with high degree of nondeterminism, deep nested control loops, and requiring strictly bounded tester response time. Tuning the planning horizon of the RPT allows a trade-off to be found between close to optimal test length and scalability of tester behavior with computationally feasible expenses.

Appropriate laboratory testing can provide insights into both the cause and possible interventions for digestive dysfunction. This chapter describes certain functional medicine laboratory testing that has been available for a number of years, as well as some of the recently available testing that is based on new scientific discoveries, and the development of next-generation high-throughput sequencing and mass spectrometry technologies. As with all laboratory testing, the results of these tests must be taken in the context of the overall clinical picture. A knowledge of the methodologies used will provide an understanding of the pros and cons of each test, and will enable the appropriate use of testing that is likely to be an out-of-pocket expense.

Full textAbstract:
This chapter means to explain the tribological behavior of polymer-based materials, to support a beneficial introducing of those materials in actual applications based on test campaigns and their results. Generally, the designers have to take into consideration a set of tribological parameters, not only one, including friction coefficient, wear, temperature in contact, contact durability related to application. Adding materials in polymers could improve especially wear with more than one order of magnitude, but when harder fillers are added (as glass beads, short fibers, minerals) the friction coefficient is slightly increased as compared to neat polymer. In this chapter, there are presented several research studies done by the authors, from which there is point out the importance of composite formulation based on experimental results. For instance, for PBT sliding on steel there was obtained a friction coefficient between 0.15 and 0.3, but for the composite with PBT + micro glass beads, the value of friction coefficient was greater. Adding a polymer playing the role of a solid lubricant (PTFE) in these composites and also only in PBT, decreased the friction coefficient till a maximum value of 0.25. The wear parameter, linear wear rate of the block (from block-on-ring tester) was reduced from 4.5 μm/(N⋅km) till bellow 1 μm/(N⋅km) for a dry sliding regime of 2.5…5 N, for all tested sliding velocities, for the composite PBT + 10% glass beads +10% PTFE, the most promising composite from this family of materials. This study emphasis the importance of polymer composite recipe and the test parameters. Also there are presented failure mechanisms within the tribolayer of polymer-based materials and their counterparts.

Full textAbstract:
In this study, work was carried out to investigate the fatigue life of engine bearings. A mathematical model was developed which utilises Miner’s rule to work out the total damage to an engine bearing when it is subject to all sorts of operational conditions. Given the fact that bearing fatigue rating has been traditionally tested against the specific load applied to bearings in test rigs, it was appropriate to develop a model using the specific load applied to a bearing, instead of the stress values in the bearing lining material. The model was then used to compare the life of con-rod bearings of a high performance diesel engine used on the road to that tested in the lab on test beds. The analysis showed the test procedure used in lab tests induced more severe damage than in the engine bearings in normal road use for design life.

Full textAbstract:
Effect of hydrogen on the slow strain rate tensile (SSRT) properties of five types of austenitic stainless steels, which contain small amounts of additive elements (e.g., nitrogen, niobium, vanadium and titanium), was studied. Some specimens were charged by exposing them to 100 MPa hydrogen gas at 543 K for 200 hours. The SSRT tests were carried out under various combinations of specimens and test atmospheres as follows: (i) non-charged specimens tested in air at room temperature (RT), (ii) non-charged specimens tested in 0.1 MPa nitrogen gas at 193 K, (iii) hydrogen-charged specimens tested in air at RT, (iv) hydrogen-charged specimens tested in 0.1 MPa nitrogen gas at 193 K, and (v) non-charged specimens tested in 115 MPa hydrogen gas at RT. In the tests without hydrogen (i.e., cases (i) and (ii)), the reduction of area (RA) was nearly constant in all the materials, regardless of test temperature. In contrast, in the tests of internal hydrogen (cases (iii) and (iv)), RA was much smaller at 193 K than at RT in all the materials. It was revealed that the susceptibility of the materials to hydrogen embrittlement (HE) can successfully be estimated in terms of the nickel equivalent, which represents the stability of austenite phase. The result suggested that the nickel equivalent can be used for evaluating the material compatibility of austenitic stainless steels for hydrogen service.

Full textAbstract:
The problem with model tests for cavitation phenomena are the so-called “scale effects”. There are numerous examples where the model was observed to be cavitation free at design operation conditions, however, the prototype suffered extensive cavitation to severe damage under similar conditions. The real heart of a successful cavitation study is to scale the information from model test to prototype conditions correctly. Therefore many efforts are made world wide to find relations for the most crucial scale effects associated with size and velocity. After carrying out extensive test series on all kinds of test body families at the VAO, by taking care of the test water quality with respect to its cavitation susceptibility, strikingly simple and clear relations for scale effects appeared. In order to check these scaling relations comparison tests were carried out in three different institutes: The Brodarski Institute (BI) in Zagreb, the Wuhan University (WHU), and the China Ship Scientific Research Center (CSSRC) in Wuxi. The test results of the model body families tested in the new CLCC at CSSRC do not confirm the velocity scaling relation found at the VAO, however, this velocity scaling relation is confirmed very well by the results of WHU and BI. On the other side all results do show a distinct size scale effect and confirm the size scaling relation.

Full textAbstract:
CGT 301 is a recuperated, single-shaft, ceramic gas turbine for cogeneration capable of continuous full load application. In order to reduce its size, thermal stress, and deformations, ceramic parts are designed axi-symmetrically. The combustor is located on a shaft axis just before the turbine, therefore it does not have a large scroll. The turbine is a two-stage axial flow-type with ceramic blades. For the first phase of the program, the primary-type gas turbine with all-metallic parts was fabricated and tested under various conditions. The test results confirmed the rotation stability of the gas turbine. After the test of preliminary metallic gas turbine, all-ceramic parts were fabricated and various tests were carried out to confirm their reliability. The configuration and structure of the ceramic turbine were improved based on the data obtained from the tests of the primary-type gas turbine and the fundamental tests for ceramic components. The primary-type ceramic gas turbine of TIT 1200°C was designed and fabricated for the second phase of the program. This paper outlines the concept of the ceramic component design, test results of ceramic parts in the hot section, and the engine test.

Full textAbstract:
Pretensioned concrete prisms made with five different prestressing strand types (four 7-wire strands and one 3-wire strand) were load tested to failure to understand the effect of strand indentation types on the development length and bonding performance of these different reinforcements. The prestressing strands were denoted SA, SB, SD, SE and SF. SA was a smooth strand while the other four were indented strands. All strands utilized in manufacturing ofprisms had diameter of 3/8″ (9.52 mm). Among all types of strands, SF was the only 3-wire strand and the remaining strands were all 7-wire strands. For all types of strands, four straight strands were embedded into each concrete prism, which had a 5.5″ (139.7 mm) × 5.5″ (139.7 mm) square cross section. The strands were tensioned to 75 percent of ultimate tensile strength of strands and gradually de-tensioned when the concrete compressive strength reached 4500 psi (31.03 Mpa). A consistent concrete mixture with type III cement, water-cement ratio of 0.32 and a 6-in. slump was used for all prisms. Prisms were load tested in 3-point-bending at different embedment lengths to obtain estimations of the development length of each type of strand. Two out of three identical 69-in.-long (175.26 cm) prisms were load tested at one end and one was tested at both ends for each reinforcement type evaluated. First prisms were tested at 28-in. (71.12 cm) from the end, while second prisms were tested at 20-in. (33.02 cm) from the end. Third prisms were loaded at 16.5-in. (41.9 cm) from one end and 13-in. (33.02 cm) from the other end. Thus, a total of 20 load tests (5 strand types × 4 tests each) were conducted in this study. During each test, a concentrated load with the rate of 900 lb/min (4003 N/min) was applied at mid-span until failure occurred. Values of load, mid-span deflection, and strand endslip were continuously monitored and recorded during each test. Plots of load-vs-deflection were then compared for prisms with each strand type and span, and the maximum sustained moment was also calculated for each test. The load tests revealed that there is a large difference in the development length of the strands based on their indentation type.

Test rig results and their comparison with computational analyses of a highly-loaded 11-stage compressor for a newly developed industrial gas turbine will be presented in this paper. The scope of the tests has been validation of aerodynamic and mechanical features of the bladed flow path to meet both the demands for single- and dual-shaft operation of the gas turbine. The test was carried out in three phases using extensive instrumentation. In phase 1 the front stages have been tested, and in phase 2 the test of the full 11-stage compressor was performed including numerous aerodynamic and structural check-outs. Vane and blade vibration modes were measured in all rows with numerous strain gauges using a telemetry system and Tip Timing, which additionally was applied to the front stage rotors. Concerning the mechanical design, finite element predictions of the vibration modes of all blades and vanes were carried out in the design phase to guarantee safe and resonance-free operation for a wide range of operational speeds which could be verified by the test data up to higher modes. Flow field computations were carried out with both a through flow solver and full 3-D viscous multistage solver based on Denton’s TBLOCK, where all rotor and stator flow fields had been solved simultaneously and compared with experiments. The effects of tip clearance and stator cavities on compressor performance have been taken into account by the computational analysis. Effects of inlet distortion were examined in phase 3. Comprehensive comparisons of computed and measured results will be presented. The extensive instrumentation gave also insight into flow details as vane pressure distributions and total pressure profiles in span wise direction. It will be shown that the agreements of predicted and measured data were excellent.

Full textAbstract:
The behaviour of the tyre plays an important role in the vehicle handling. Thus for the analysis of vehicles and road safety it is necessary to take into account the forces and moments generated at contact patch. An accurate tyre model that estimates these forces and moments is highly essential for the studies of vehicle dynamics and control. Most of the tyre models have been developed for high speed, combined forces, etc. But, usually, automobile vehicles run at low speeds during an important part of their operating life (less than 60 km/h) and in steady state conditions. Furthermore, during vehicle inspection and maintenance of the steering and brake system, by means of sideslip tester and roller brake tester respectively, the forces transmitted by the tyres are measured, all of these inspections are carried out at low speeds. Therefore, it is particularly interesting to develop a model of the contact patch tyre-pavement for low speeds without the complexity of models that cover a wide speed range but with a bigger precision at low speeds. The dynamometer plate has proved to be an appropriate test equipment to characterise the tyre-pavement contact at low speed and the steering geometry and wheel alignment. It has the feature of being able to carry out tests for any type of tyre allowing to test with a great flexibility and operating speed. For this reason, the dynamometer plate has been chosen as test equipment. The main aim of this research is to set up a contact model between tyre and pavement at low speed, based on the measurement of longitudinal and lateral forces. The experimental tests carried out by means of the dynamometer plate have allowed to establish a relationship between influence variables and the longitudinal and lateral forces in the contact patch for steady state low speeds. A sensibility study has shown that the most influential variables in the forces of the contact patch are the pressure, the vertical force and the toe angle. However, the influence of temperature and camber angle is lower for the defined model conditions. A test methodology that allows carrying out the experimental tests in a systematic and controlled way in the dynamometer plate has also been developed.

Full textAbstract:
In a component design at elevated temperature, creep-fatigue is one of the most important failure modes, and assessment of creep-fatigue life in structural discontinuity is important issue to evaluate structural integrity of the components. Therefore a lot of creep-fatigue life evaluation methods were proposed until now. To compare and assess these evaluation methods, a series of creep-fatigue tests was carried out with notched specimens. All the specimens were made of Mod.9Cr-1Mo steel, which it is a candidate material for a primary and secondary heat transport system components of JSFR (Japan Sodium-cooled Fast Reactor). Mechanical creep-fatigue tests and thermal creep-fatigue tests were performed by using conventional uni-axial push-pull fatigue test machine and thermal gradient generating system with an induction heating coil. Stress concentration levels were adjusted by varying the diameters of notch roots in the both tests. In the test, creep-fatigue lives, crack initiation and propagation processes were observed by digital micro-scope and replica method. Besides those, a series of elastic Finite Element Analysis (FEA) were carried out to predict the number of cycles to failure by several creep-fatigue life evaluation methods. Then these predictions were compared with test results. Several types of evaluation methods which are stress redistribution locus (SRL) method, simple elastic follow-up method and the methods described in JSME FR (Fast Reactor) code were applied. The applicability and conservativeness of these methods were discussed. It was appeared that SRL method gave rational prediction of creep-fatigue life with conservativeness when the factor of κ = 1.6 was applied for all the conditions tested in this study. Comparison of SRL method and simple elastic follow-up method indicated that SRL method applied factor of κ = 1.6 gave the smallest creep-fatigue life in practicable stress level. JSME FR code gave an evaluation 70∼100 times conservative lives comparing with the test results.

Socioeconomically disadvantaged students (i.e. those whose scores on a constructed measure of social and cultural capital are below a specified cut-off, usually the 25th percentile) have been found to be more likely to drop out of school, repeat a grade, achieve lower levels at senior secondary school, and score lower on tests such as the Programme for International Student Assessment (PISA). Despite this association between socioeconomic disadvantage and poorer outcomes related to education, a percentage of students who come from disadvantaged backgrounds enjoy success at school. This apparent success despite the odds is of interest to researchers and educators alike – what, if any, characteristics do these academically resilient students share, why might this be and what can we learn from this group of students, however small, that might assist in improving outcomes for all students, regardless of their socioeconomic background?

Full textAbstract:
This master thesis explores the challenges for waste management business models in the field of textiles regarding the requirements of the circular economy, as well as improvement potentials in the current framework conditions. It is concerned with the research question: "Is it advisable to change the frame-work conditions at meso or macro level, with regard to business models for waste management companies in the textile sector that are oriented towards the requirements of the circular economy, and - if so - in what way?” The approach of the study is based on the delta analysis of the e Society for Institutional Analysis at the Darmstadt University of Applied Sciences. It compares the target state of the normative requirements with the actual state of the textile and waste management framework conditions and attempts to identify the gaps (the delta). Based on the delta, it develops approaches that are intended to help reduce the gaps. The thesis develops three business models for the target year 2025 in different areas: an exchange platform for sorters, recyclers and designers, an automatic sorting plant and a plant for fibre-to-fibre recycling of mixed materials. It is becoming clear that these business models cannot meet the target requirements for the circular economy. The analysis identifies the remaining gaps in the framework conditions as the main problem. For example, insufficient innovation impulses and the lack of competitiveness of secondary raw materials inhibit the actors from applying and using new technologies and business models. Restricted access to knowledge and information, as well as a lack of transparency between the actors, also prove to be problematic. In order to answer the research question, the study recommends altering the framework conditions at meso and macro level. It proposes a platform for cooperation between designers, the introduction of a material declaration system and an eco-design guideline for textiles as possible development options. In addition, this work offers a matrix of criteria to help the actors test and improve their new waste management business models regarding their suitability for the circular economy. The analysis is carried out from an outsider's perspective on the entire textile industry. It therefore cannot cover and deal with all aspects and individual circumstances of each player in detail. The necessary changes in the framework conditions that have been identified can therefore be used as a basis for further investigations.

Full textAbstract:
From this edition, the Financial Stability Report will have fewer pages with some changes in its structure. The purpose of this change is to present the most relevant facts of the financial system and their implications on the financial stability. This allows displaying the analysis more concisely and clearly, as it will focus on describing the evolution of the variables that have the greatest impact on the performance of the financial system, for estimating then the effect of a possible materialization of these risks on the financial health of the institutions. The changing dynamics of the risks faced by the financial system implies that the content of the Report adopts this new structure; therefore, some analyses and series that were regularly included will not necessarily be in each issue. However, the statistical annex that accompanies the publication of the Report will continue to present the series that were traditionally included, regardless of whether or not they are part of the content of the Report. In this way we expect to contribute in a more comprehensive way to the study and analysis of the stability of the Colombian financial system. Executive Summary During the first half of 2015, the main advanced economies showed a slow recovery on their growth, while emerging economies continued with their slowdown trend. Domestic demand in the United States allowed for stabilization on its average growth for the first half of the year, while other developed economies such as the United Kingdom, the euro zone, and Japan showed a more gradual recovery. On the other hand, the Chinese economy exhibited the lowest growth rate in five years, which has resulted in lower global dynamism. This has led to a fall in prices of the main export goods of some Latin American economies, especially oil, whose price has also responded to a larger global supply. The decrease in the terms of trade of the Latin American economies has had an impact on national income, domestic demand, and growth. This scenario has been reflected in increases in sovereign risk spreads, devaluations of stock indices, and depreciation of the exchange rates of most countries in the region. For Colombia, the fall in oil prices has also led to a decline in the terms of trade, resulting in pressure on the dynamics of national income. Additionally, the lower demand for exports helped to widen the current account deficit. This affected the prospects and economic growth of the country during the first half of 2015. This economic context could have an impact on the payment capacity of debtors and on the valuation of investments, affecting the soundness of the financial system. However, the results of the analysis featured in this edition of the Report show that, facing an adverse scenario, the vulnerability of the financial system in terms of solvency and liquidity is low. The analysis of the current situation of credit institutions (CI) shows that growth of the gross loan portfolio remained relatively stable, as well as the loan portfolio quality indicators, except for microcredit, which showed a decrease in these indicators. Regarding liabilities, traditional sources of funding have lost market share versus non-traditional ones (bonds, money market operations and in the interbank market), but still represent more than 70%. Moreover, the solvency indicator remained relatively stable. As for non-banking financial institutions (NBFI), the slowdown observed during the first six months of 2015 in the real annual growth of the assets total, both in the proprietary and third party position, stands out. The analysis of the main debtors of the financial system shows that indebtedness of the private corporate sector has increased in the last year, mostly driven by an increase in the debt balance with domestic and foreign financial institutions. However, the increase in this latter source of funding has been influenced by the depreciation of the Colombian peso vis-à-vis the US dollar since mid-2014. The financial indicators reflected a favorable behavior with respect to the historical average, except for the profitability indicators; although they were below the average, they have shown improvement in the last year. By economic sector, it is noted that the firms focused on farming, mining and transportation activities recorded the highest levels of risk perception by credit institutions, and the largest increases in default levels with respect to those observed in December 2014. Meanwhile, households have shown an increase in the financial burden, mainly due to growth in the consumer loan portfolio, in which the modalities of credit card, payroll deductible loan, revolving and vehicle loan are those that have reported greater increases in risk indicators. On the side of investments that could be affected by the devaluation in the portfolio of credit institutions and non-banking financial institutions (NBFI), the largest share of public debt securities, variable-yield securities and domestic private debt securities is highlighted. The value of these portfolios fell between February and August 2015, driven by the devaluation in the market of these investments throughout the year. Furthermore, the analysis of the liquidity risk indicator (LRI) shows that all intermediaries showed adequate levels and exhibit a stable behavior. Likewise, the fragility analysis of the financial system associated with the increase in the use of non-traditional funding sources does not evidence a greater exposure to liquidity risk. Stress tests assess the impact of the possible joint materialization of credit and market risks, and reveal that neither the aggregate solvency indicator, nor the liquidity risk indicator (LRI) of the system would be below the established legal limits. The entities that result more individually affected have a low share in the total assets of the credit institutions; therefore, a risk to the financial system as a whole is not observed.
