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.

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.

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.

AbstractThe 3-min all-out test was developed and validated on a cycle ergometer using a modification of a linear mathematical equation (1/time vs. power) obtained from the original critical power model. The purpose of this development was to obtain, in a single test, the aerobic and anaerobic capacity parameters and identify the exercise transition moment from heavy to severe intensity. The aim of this study was to propose an adaptation of the all-out 3-min cycle ergometer to a non-motorized treadmill with tethered running. In addition, we tested the reproducibility of this adapted protocol, highlighting the need for mechanical power evaluation using a specific ergometer. Consequently, 10 physically active individuals visited the laboratory 4 times for testing and data collection. The results suggested that the protocol adaptation for the 3-min all-out test for non-motorized treadmill with tethered running was reproducible and feasible. It was also possible to show that the AO3 application in this ergometer ensures the specificity of the sports that involve the running exercise, from assessment of both aerobic and anaerobic parameters, accomplished in a single day of application.

Esta infecção em sua maioria regride, porém, em seu pequeno número de casos, onde persiste, podem progredir para o câncer de colo do útero. O câncer de colo uterino é prevenível com associação a vacina e a realização de exames preventivos de rotina que detectam a lesão precursora. Objetivo: Realizar a análise socioepidemiológica do HPV, avaliar o perfil da população acometida pela doença e identificar os impactos no manejo da doença para entender como reduzir os números de casos. Materiais e métodos: O presente estudo se deu de modo descritivo realizado através de consultas de dados de bases científicas. Resultados: A técnica de citologia oncótica, como forma de rastreio do HPV e prevenção ao câncer de colo do útero, apresentou diversas limitações, como baixa a moderada sensibilidade, baixa reprodutibilidade e grande número de falso-negativos. O rastreio do HPV por PCR em tempo real apresentou-se como o método mais eficaz no diagnóstico do HPV por apresentar maior sensibilidade e eficiência para o rastreio. A educação sexual mostrou-se indispensável tanto para informações a respeito da doença, quanto para a prevenção. Discussão: São necessários investimentos no desenvolvimento de práticas para a promoção da saúde, além da campanha realizada atualmente para vacinação contra HPV, é preciso associar a campanhas de uso de preservativo e campanhas de incentivo a realização de exames de rastreamento, além da inclusão de educação sexual em escolas e abordagem pela família. Assim é possível conscientizar a população, refletindo diretamente na redução da contaminação. Conclusão: O teste de rastreamento disponibilizado na rede pública e o acesso à informação sobre medidas de prevenção se mostraram como fatores que dificultam o manejo do HPV. Ainda com todas as informações levantadas, são necessárias mais avaliações para que assim projetos mais efetivos sejam implementados para o controle do HPV.Palavras chave: HPV, Câncer de colo do útero, Teste de Papanicolaou, HPV, PCR, PapanicolaouABSTRACTIntroduction: Human papilloma virus, or HPV, is a virus that infects the skin or mucosa, transmitted through direct or indirect contact with the affected area. This infection mostly regresses, however, in its small number of cases, where it persists, it can progress to cervical cancer in women. Cervical cancer is preventable in combination with the vaccine and routine preventive examinations that detect the precursor lesion. Objective: Perform the socio-epidemiological analysis of HPV, evaluate the profile of the population affected by the disease and identify the impacts on the management of the disease for understand how to reduce number of cases. Materials and methods: The present study was carried out in a descriptive way, carried out through scientific data consultations. Results: The oncotic cytology technique, as a way of screening HPV and preventing cervical cancer, presented several limitations, such as low to moderate sensitivity, low reproducibility and a large number of false negatives. HPV screening by real-time PCR was shown to be the most effective method for diagnosing HPV because it has greater sensitivity and efficiency for screening. Sex education proved to be indispensable both for information about the disease and for prevention. Discussion: Investments are needed in the development of practices for health promotion, in addition to the campaign currently carried out for vaccination against HPV, it is necessary to associate it with campaigns of condom use and campaigns to encourage the performance of screening tests, in addition to the inclusion of sexual education in schools and family approach. Thus it is possible to raise awareness among the population, directly reflecting on the reduction of contamination. Conclusion: The screening test made available on the public network and access to information on preventive measures proved to be factors that hinder the management of HPV. Even with all the information collected, more evaluations are necessary so that more effective projects are implemented for the control of HPV.Keywords: HVP, Cervical cancer, HPV Test, PCR, PAP smear

The study presents the results of the quantitative research focusing on the effectiveness of the inquiry based science education (IBSE) in correlation to motivation types of learners. Reflecting the fact that the learning results are impacted by the inner motivation, the main aim of the research was to find out whether there are differences in IBSE effectiveness in four motivation types - explorers, directors, coordinators, and accurators. The IBSE approach was applied for the period of five months to 395 fifteen-year-old learners of Czech lower secondary schools. The IBSE effectiveness was tested before the instruction (pre-test), immediately after it (post-test1) and four months later (post-test2). The results of four motivation types were compared. Directors reached the best results in post-test1; explorers in post-test2; accurators´ results were the worst of all. These findings show that the IBSE cannot be applied as a universal method; teachers should adjust its exploitation to learners’ individual particularities. Key words: educational practice, inquiry-based science education, learners’ motivation types, quantitative research, testing.

Memory modules are widely used in varies kind of electronics system design. The capacity of the memory modules has increased rapidly since the past few years in order to satisfy the high demand from the end-users. The memory modules’ manufacturers demand more units of automatic test equipment (ATE)to increase the production rate. However, the existing ATE used in the industry to carry out the memory testing is too costly(at least a million dollars per ATE tester). The low-cost memory testers are urgently needed to increase the production rate of the memory module. This has in spired us to design a low-cost memory tester. A low-cost memory fault detection tester with all the major fault detection algorithms that used in industry is modelled using Very High Speed Integrated Circuit Hardware Description Language (VHDL) in this paper to support the need of the low-cost ATE memory tester. The fault detection algorithms modelled are MATS+ (Modified Algorithm Test Sequence), MATS++, March C, March C-, March X ,March Y, zero-one and checkerboard scan tests. PERL program is used to analyse the simulation results and a log file will be generated at the end of the memory test. Extensive simulation and experimental test results show that the memory tester modelled covers all the memory test algorithms used in the industry. The low-cost memory fault detection tester designed provides the 100% fault detection coverage for all memory defects.

RESUMO - O objetivo deste estudo foi avaliar as características morfoagronômicas do híbrido simples de milho em função da aplicação de diferentes intensidades de desfolha artificial, realizadas no estádio R1 de desenvolvimento. O experimento foi conduzido na área experimental do Instituto Federal Goiano,em Morrinhos-GO, na safra 2015/2016. Foi aplicado o delineamento de blocos completamente casualizados, com oito tratamentos e quatro repetições, sendo eles: remoção de uma folha acima e uma abaixo da espiga; remoção de duas folhas acima e abaixo da espiga; remoção de três folhas acima e abaixo da espiga; remoção de todas as folhas da planta; remoção de todas as folhas acima da espiga; remoção de todas as folhas abaixo da espiga; remoção da folha da espiga; e testemunha sem desfolha. Os caracteres avaliados foram: estande de plantas, número de plantas acamadas, prolificidade, densidade de colmo, comprimento e diâmetro de espiga, comprimento de grão, massa de mil grãos, massa de grãos espiga-1 e produtividade. Os dados foram submetidos à análise de variância pelo teste F a 5% de probabilidade, observando que todas as variáveis avaliadas foram influenciadas quanto aos efeitos dos tratamentos empregados. O enchimento dos grãos esteve intimamente relacionado à fotossíntese.

MORPHOAGRONOMIC CHARACTERISTICS OF MAIZE AS A FUNCTION OF DIFFERENT LEVELS OF ARTIFICIAL DEFOLIATION ABSTRACT - The objective of this study was to evaluate of morphoagronomic characteristics of simple hybrids of maize, depending on the application of different intensities of artificial defoliation, carried out in R1, when the style-stigma were fertilized. The experiment was conducted in an experimental area of the Instituto Federal Goiano, Campus Morrinhos, State of Goiás, Brazil, during the agricultural year 2015/2016. We applied the design of completely randomized block with eight treatments, in four replications: removal of a leaf above and one below the ear; removal of two leaves above and below the ear; removal of three leaves above and below the ear; removal of all leaves of the plant; removal of all leaves above the ear; removal of all leaves below the ear; removal of the leaf of the ear; and control without defoliation. The traits evaluated were stand of plants, number of plant lodging, prolificacy, density, length and diameter of the cob, length of a grain, weight of a thousand grains, grain mass cob-1 and productivity. The data obtained were subjected to analysis of variance by F test at 5% probability, noting that all variables were influenced as to the effects of the treatments used. The filling of grains is closely related to photosynthesis. Without the leaves, this phase was fully damaged.Keywords: Zea mays L., photoassimilates, translocation, leaf area index, yield.

Testing and examining go on in higher education all the time through continuous assessments and end semester examinations. The grades scored by students determine not only academic mobility but eventually who get employed in the job market, which seems to be shrinking all over the world. Those charged with testing are often staff who have higher qualifications in their subject areas but are not necessarily teaching or examination experts. Against this background, the researcher wanted to find out what was happening at selected university across three schools: Social Studies, Education and Science. The university is fairly young having been awarded its charter twenty years ago. The paper asked two questions namely, at what levels of Bloom’s Taxonomy are lecturers asking examination questions? Secondly, do the level and balance of questions show growth in examining skills? The study evaluated over 1039 questions from randomly selected examination papers from the Examinations Office for the academic years from 2014/15 to 2017/18 (three academic years). A guide from the list of verbs used in Anderson s (revision of Bloom was used to analyze the questions. Descriptive statistics were used to describe the trends in testing for each year. ANOVA and t-tests were used to find out if there were significant differences between numbers across categories and within categories. The results of the study show that most examination questions are at the levels of remember (literal) and knowledge (understand). In 2016/17 and 2017/18 academic years, there were significant differences in the percentage of questions examined in these two categories. However, it seems from the study, that testing or examining skills do not grow through the practice of setting questions. There is need for examiners to be trained to use the knowledge in setting questions that discriminate effectively across the academic abilities of students they teach.

Full textAbstract:
Recent research suggests that acute consumption of pharmacological analgesics can improve exercise performance, but the ergogenic potential of ibuprofen (IBP) administration is poorly understood. This study tested the hypothesis that IBP administration would enhance maximal exercise performance. In one study, 13 physically active males completed 60 × 3-s maximal voluntary contractions (MVCs) of the knee extensors interspersed with 2-s passive recovery periods, on 2 occasions, with the critical torque (CT) estimated as the mean torque over the last 12 contractions (part A). In another study, 16 active males completed two 3-min all-out tests against a fixed resistance on an electronically braked cycle ergometer, with the critical power estimated from the mean power output over the final 30 s of the test (part B). All tests were completed 60 min after ingestion of maltodextrin (placebo, PL) or 400 mg of IBP. Peripheral nerve stimulation was administered at regular intervals and electromyography was measured throughout. For part A, mean torque (IBP: 60% ± 13% of pre-exercise MVC; PL: 58% ± 14% of pre-exercise MVC) and CT (IBP: 41% ± 16% of pre-exercise MVC; PL: 40% ± 15% of pre-exercise MVC) were not different between conditions (P > 0.05). For part B, end-test power output (IBP: 292 ± 28 W; PL: 288 ± 31 W) and work done (IBP: 65.9 ± 5.9 kJ; PL: 65.4 ± 6.4 kJ) during the 3-min all-out cycling tests were not different between conditions (all P > 0.05). For both studies, neuromuscular fatigue declined at a similar rate in both conditions (P > 0.05). In conclusion, acute ingestion of 400 mg of IBP does not improve single-leg or maximal cycling performance in healthy humans.

soja é umas das culturas mais produzidas no mundo, tendo safra na casa dos milhões de toneladas/ano. O aumento na produção dessa cultura permeia o desenvolvimento de tecnologias, que permitam conservar a produtividade e minimizar os dados ambientais oriundos de seu manejo. Uma opção é a inoculação de micro-organismos endofíticos que contribuem com o desenvolvimento dessa cultura. Objetivando averiguar o potencial de produção do fitormônio ácido indol acético (AIA) e solubilização de fosfato de cálcio por bactérias endofíticas isoladas de Echinodorus scaber e avaliar sua aplicação na promoção de crescimento de plântulas de soja, foram acessadas 61 bactérias endofíticas de E. scaber para os testes. A produção de AIA foi quantificada por método colorimétrico e a solubilização de fosfato de cálcio procedeu-se com inoculação das linhagens endofíticas, em meio de cultura especifico e, posteriormente, o índice de solubilização foi calculado. Para o teste de promoção de crescimento, sementes de soja foram microbiolizadas com linhagens de bactérias produtoras de AIA e solubilizadoras de fosfato de cálcio. Foram avaliadas a porcentagem de germinação, índice de velocidade de emergência e a massa seca das plântulas de soja. As linhagens de interesse foram identificadas pelo sequenciamento parcial do gene 16S rRNA. Os resultados evidenciaram, que todas as bactérias endofíticas de E. scaber avaliadas são capazes de produzir AIA e, grande parte delas pode solubilizar fosfato de cálcio in vitro e que algumas linhagens desses micro-organismos possuem traços de promoção de crescimento de plântulas de soja, evidenciado pelo aumento de massa seca.Palavras-chave: Ácido Indolacético.

The increase in the production of this culture permeates the development of technologies that allow to conserve the productivity and to minimize the environmental data arising from its handling. One option is the inoculation of endophytic microorganisms that contribute to the development of this culture. In order to investigate the production potential of indole acetic acid phytormonium (AIA) and calcium phosphate solubilization by endophytic bacteria isolated from Echinodorus scaber and to evaluate its application in the promotion of soybean seedlings growth, 61 endophytic E. scaber bacteria were tested . The AIA production was quantified by colorimetric method and the calcium phosphate solubilization was carried out with inoculation of the endophytic lines in specific culture medium and afterwards the solubilization index was calculated. For the growth promotion test, soybean seeds were microbiolized with strains of AIA producing bacteria and calcium phosphate solubilizers. The germination percentage, the emergence speed index and the dry mass of the soybean seedlings were evaluated. The lines of interest were identified by the partial sequencing of the 16S rRNA gene. The results showed that all the endophytic bacteria of E. scaber evaluated are capable of producing AIA and most of them can solubilize calcium phosphate in vitro and that some strains of these microorganisms have growth promoting traits of soybean seedlings evidenced by the increase of dry mass.Keywords: Indoleacetic Acid.

Line ? tester analysis was carried out in willows (Salix spp.) to determine the genetic interaction in the expression of various quantitative characters related to productivity. Combining ability revealed that the estimates of GCA variance (?2 GCA) were more than the SCA variance (?2 SCA) for all the characters studied. Later the gene action study revealed that additive variance was observed more than the dominance variance for all the parameters studied. The proportional contribution of lines were higher than individual contribution of testers or line ? tester interaction except for fresh root weight, dry shoot weight, dry root weight and total dry weight where the contribution of interactions was more. Line PN 227 and tester Austree and J 795 were found to be good general combiners and thus appeared to be worthy of exploiting in Salix improvement through breeding and recurrent selection followed by cloning for developing commercial superior clones. On the basis of mean performance and significant desirable SCA effects, the combinations PN 227 ? Austree, PN 227 ? NZ 1140 and J 799 ? Austree were found to be the most promising families for growth and biomass characters and are recommended for within family selections followed by heterotic breeding.

Full textAbstract:
The slow component of pulmonary O2 uptake (V̇o2) during constant work rate (CWR) high-intensity exercise has been attributed to the progressive recruitment of (type II) muscle fibers. We tested the following hypotheses: 1) the V̇o2 slow component gain would be greater in a 3-min all-out cycle test than in a work-matched CWR test, and 2) the all-out test would be associated with a progressive decline, and the CWR test with a progressive increase, in muscle activation, as estimated from the electromyogram (EMG) of the vastus lateralis muscle. Eight men (aged 21–39 yr) completed a ramp incremental test, a 3-min all-out test, and a work- and time-matched CWR test to exhaustion. The maximum V̇o2 attained in an initial ramp incremental test (3.97 ± 0.83 l/min) was reached in both experimental tests (3.99 ± 0.84 and 4.03 ± 0.76 l/min for all-out and CWR, respectively). The V̇o2 slow component was greater ( P < 0.05) in the all-out test (1.21 ± 0.31 l/min, 4.2 ± 2.2 ml·min−1·W−1) than in the CWR test (0.59 ± 0.22 l/min, 1.70 ± 0.5 ml·min−1·W−1). The integrated EMG declined by 26% ( P < 0.001) during the all-out test and increased by 60% ( P < 0.05) during the CWR test from the first 30 s to the last 30 s of exercise. The considerable reduction in muscle efficiency in the all-out test in the face of a progressively falling integrated EMG indicates that progressive fiber recruitment is not requisite for development of the V̇o2 slow component during voluntary exercise in humans.

Abstract The biopsy of live animal testes is an important clinical manipulation to control spermatogenesis and reproductive system pathologies. The aim was to develop a method of boar testes biopsy using a biopsy gun with ultrasound guidance and to investigate the influence of this procedure on the boar testes parenchyma and quality of ejaculate. The biopsy was carried out in six 8-month-old boars. Fourteen days prior to and 21 days after biopsy, the quality of ejaculate was examined (weight of ejaculate; concentration and motility of spermatozoa) with a seven-day intervals. Ultrasound images of the testes parenchyma were recorded three times: directly before and 15 minutes after the biopsy, then 21 days after the procedure. The testes biopsies of generally anesthetized boars were performed with the biopsy gun for needle biopsy with a 12cm long, disposable 16-gauge needle 1.8mm in diameter (Vitesse) through 1cm skin incision in the depth of 1.2-1.6cm of parenchyma. Fifteen minutes after the biopsy, macroscopic injures of the parenchyma of all the boar testes were not detected in the ultrasound image. Twenty one days after biopsy, the hyperechogenic line 0.1-0.2cm in diameter was seen in the testes parenchyma of six boars in the depth of 1.2-1.6cm. The biopsy of boar testes did not influence the quality of boars ejaculate. The ultrasonographic examination of boar testicles before the biopsy reduced possibilities to traumatize large blood vessels of the testes. A perfect boar testicular biopsy was easy to perform using ultrasonographic examination in the pigsty conditions.

Background. Cryptorchidism or undescended testes is the most common disorder of the male endocrine glands in children. With the advancements in laparoscopic techniques and instruments, laparoscopic orchidopexy has become the standard procedure in the management of nonpalpable undescended testes. Aim. To evaluate and determine the therapeutic role, sensitivity, and specificity of laparoscopy in localizing nonpalpable testes and the mean operative time, the conversion rate (and reasons thereof), postoperative wound infection, postoperative stay, and time taken for return to daily activities following laparoscopic orchidopexy or orchidectomy. Materials and Methods. This was a prospective study carried out in the Postgraduate Department of Surgery, Government Medical College, Srinagar, J&K, India, from May 2008 to August 2011. All patients who presented to the outpatient department with complaints of absent testes were examined, and the ones with nonpalpable testes were included in the study. Results. The mean operative time for bilateral and unilateral nonpalpable testis was 102.76 and 53.67 minutes, respectively. Minor postoperative wound infections were noted in 4 of our patients. Mean duration of hospital stay was 14.23 hrs for unilateral cases and 16.27 hrs for bilateral cases. Patients who underwent laparoscopic orchidopexy resumed their normal activities within 4 ± 1 days. Conclusion. Laparoscopy clearly demonstrates the anatomy and provides visual information upon which a definitive decision can be made for further management of the undescended nonpalpable testis.

Designing problem and theoretical analyses of steel-concrete composite structures are especially emphasized in bridge engineering. Method of modelling composite constructions developed and established by standards had been improved by use of finite element method and modern software. By this paper authors wanted to point out the importance of adequate structure modelling assuming all features of steel-concrete bond, and comparing results of experimental research with results of software calculation based on FEM and calculation based on plane theory approach with certain simplifications. Because of research tests necessities the bridge was loaded with four heavy test vehicles. Results, which are represented graphically and numerically were essence for suggestion of giving advantages to area element discretization of composite section over the other one.

Some prominent representatives of the method have replied in turn that simulations with artificial data are unsuited for assessing QCA. We take issue with either position in this impasse. On the one hand, we argue that data-driven evaluations of the correctness of a procedure of causal inference require artificial data. On the other hand, we prove all previous attempts in this direction to have been defective. For the first time in the literature on configurational comparative methods, we lay out a set of formal criteria for an adequate evaluation of QCA before implementing a battery of inverse-search trials to test how this method performs in different recovery contexts according to these criteria. While our results indicate that QCA is correct when generating the parsimonious solution type, they also demonstrate that the method is incorrect when generating the conservative and intermediate solution type. In consequence, researchers using QCA for causal inference, particularly in human-sensitive areas such as public health and medicine, should immediately discontinue employing the method’s conservative and intermediate search strategies.

Consider the multiple testing problem of testingmnull hypothesesH1,…,Hm, among whichm0hypotheses are truly null. Given theP-values for each hypothesis, the question of interest is how to combine theP-values to find out which hypotheses are false nulls and possibly to make a statistical inference onm0. Benjamini and Hochberg proposed a classical procedure that can control the false discovery rate (FDR). The FDR control is a little bit unsatisfactory in that it only concerns the expectation of the false discovery proportion (FDP). The control of the actual random variable FDP has recently drawn much attention. For any level1−α, this paper proposes a procedure to construct an upper prediction bound (UPB) for the FDP for a fixed rejection region. When1−α=50%, our procedure is very close to the classical Benjamini and Hochberg procedure. Simultaneous UPBs for all rejection regions' FDPs and the upper confidence bound for the unknownm0are presented consequently. This new proposed procedure works for finite samples and hence avoids the slow convergence problem of the asymptotic theory.

A novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease (COVID)-19, that emerged as a major pandemic. SARS-CoV-2 was identified as a betacoronavirus. Nucleocapsid protein (NP) is evolutionary high protein homologies and solid structure protein for SARS-CoV-2 detection as opposed to other proteins, that aren`t reliable as a single viral antigen during diagnostics methods. The viral RNA can be detected from nasal and pharyngeal swabs and bronchoalveolar lavage samples by PCR assay. However, the wrong collection of samples can lead to false-negative diagnosis and have dangerous consequences at this stage of pandemic. One of efficient and accurate methodological approaches for the screening of pathogens are serological assays. Aim. Evaluation and comparison of the sensitivity of invented DIA®-SARS-CoV-2-Ag-R enzyme-linked immunosorbent assay (ELISA)-based test system and commercial rapid tests, which detect the viral antigen of SARS-CoV-2. Methods. We carried out a comparison of DIA®-SARS-CoV-2-Ag-R and existed commercial test systems, which are used to detect the antigen of SARS-CoV-2 virus. Rapid tests are intended for nasopharyngeal swabs, but we proposed a protein of our own manufacture – recombinant NP as a calibrator. The detection limit was calibrated by standard CFAR #100982 NIBSC, UK. We had determined levels of NP (1400, 900, 750, 640 and 280 pg/mL) that we used as a sample for the rapid tests. The COVID-19 Ag Rapid Tests were performed according to the manufactures instructions at room temperature. Results. DIA®-SARS-CoV-2-Ag-R detected 10 pg/mL of in-house standard of recombinant SARS-CoV-2 NP. The positive results were observed using 1400, 900, 750 pg/mL, while 640 and 280 pg/mL samples were performed as negative in ABBOTT-PanBio test. The rapid tests manufactured by МBU, BIOTIME, Core Technology, SD BIOSENSOR and Turklab showed positive results only in 1400 pg/mL concentration. NP of lower levels was detected as a negative sample. The LEPU MEDICAL test was evaluated as positive sample using 900 pg/mL. The rapid test manufactured by Green Cross Medical Science Corp. showed negative results for all levels of NP. It can mean that the sensitivity of test is lower and demands higher level of antigen to detect the presence of SARS-CoV-2. Conclusions. The study presented an excellent analytical sensitivity of DIA®-SARS-CoV-2-Ag-R against commercial Antigen rapid tests. Thus, invented ELISA test system can be recommended for widespread usage for detection and confirmation of acute stage of SARS-CoV-2 infection.

Full textAbstract:
AbstractOn the basis of embryo and seed colour, morphology, accumulation of fresh and dry weight, seed development of Chinese cabbage (Brassica rapasubsp.pekinensis) can be divided into 10 discrete but contiguous stages. Precocious germination (PG) occurs in the seeds of a Chinese cabbage mutant on the parent plant mainly during the maturation period (from stage 5 to 8), with either the radicle or the cotyledon protruding out of the testa. All plants of the mutant line produce some PG seeds, but among the seeds, only 18% (maximum) germinate precociously. The developing mutant seeds have higher water contents and lower dry weights than those of the wild-type and are less tolerant of desiccation. The testa structure of Chinese cabbage seed is similar to that of otherBrassicaspecies. In developing seeds, it consists of the epidermis, subepidermis, palisade layer and pigmented layers, while in the mature dry seeds, all the cell layers except the palisade layer are crushed into non-cell structures and are stacked on the outer and inner faces of the palisade layer; the aleurone layer is fused to the testa. An alteration in testa structure of the mutant seeds (both non-germinated and precociously-germinated seeds) is probably related to PG. The secondary cell wall materials are less, or not deposited on the radial and basal walls of the palisade cells on the adaxial side of the testa, which could result in a weaker mechanical restraint, thus leading to PG.

Ecossistemas lênticos de pequeno porte respondem rapidamente às condições ambientais, influenciando a comunidade planctônica devido às flutuações bióticas e abióticas do corpo d’água. Este estudo teve como objetivo analisar os parâmetros físico-químicos e a identificação da comunidade planctônica (fitoplâncton, zooplâncton e bacterioplâncton) presentes no reservatório, correlacionando esses organismos em um ambiente oligotrófico. As análises foram realizadas mensalmente no período de julho/2014 a junho/2016. A análise de todos os parâmetros físico-químicos e biológicos foi realizados de acordo com metodologia oficial. Empregou-se ferramentas estatísticas multivariadas (ACP) e teste de Pearson para avaliar a correlação entre as variáveis abióticas e a biomassa total de cada grupo planctônico. Nesta pesquisa encontrou-se uma relação positiva entre as biomassas totais da comunidade zooplânctonica e fitoplânctonica, entretanto componentes do bacterioplancton, não foi significativo. Estes resultados indicaram que a predação e/ou competição não são relações ecológicas significativas entre as espécies zooplanctônicas e fitoplanctônicas presentes neste ecossistema oligotrófico, existindo assim uma relação favorável entre os grupos estudados. Desta forma, o desenvolvimento desses organismos foi influenciado pelas mesmas variáveis abióticas (manganês, dureza e temperatura), atuando de forma direta no estabelecimento de suas biomassas. A B S T R A C TSmall lentic ecosystems respond rapidly to environmental conditions, influencing the planktonic community due to the biotic and abiotic fluctuations of the water body. This study aimed to analyze the physicochemical parameters and identification of the planktonic community (phytoplankton, zooplankton, and bacterioplankton) present in the reservoir, correlating these organisms in an oligotrophic environment. The analyses were performed monthly from July/2014 to June/2016. The analysis of all physicochemical and biological parameters was carried out according to the conventional methodology. Multivariate statistical tools (PCA) and Pearson's test were used to evaluate the correlation between the abiotic variables and the total biomass of each planktonic group. In this research was found a positive relation between the total biomasses of the zooplanktonic community and phytoplanktonic. However, components of bacterioplankton were not significant. These results indicate that predation and competition are not significant ecological relationships between zooplanktonic and phytoplanktonic species present in this oligotrophic ecosystem, and there is a favorable relationship between the studied groups. In this way, the development of these organisms was influenced by the same abiotic variables (manganese, hardness, and temperature), acting directly in the establishment of their biomasses.Keywords: plankton, reservoir, abiotic factors.

Using air lubricants, wear tests of Si3N4-hBN composites with different hexagonal boron nitride (hBN) volume fraction sliding against Si3N4ceramic were carried out on a MMU-5G type pin-on-disc tester. For comparison, Si3N4/Si3N4pairs were also tested under the same conditions. The worn surfaces of specimens were observed under scanning electron microscope (SEM). Furthermore, the wear debris were analyzed by using X-ray diffraction (XRD). Wear debris layers are formed on the wearing surface when Si3N4-hBN composites slide against Si3N4ceramic under air lubrication. In this situation, the friction coefficients are as high as 0.80-1.20 and the wear coefficients are above 10-5 mm3/Nm for all materials tested.

The analysis was conducted on the national database of the station tests carried out between May 1996 and February 2001, using the Hungarian Large White (LW) and Hungarian Landrace (LR) breeds, and the A-line of the Ka-Hyb hybrid (MLW). Days of test, total amount of feed consumed and valuable cuts were taken into the analysis to test the random distribution of the animals' phenotypic measurements and predicted breeding values across the contemporary groups of origin. The phenotypic measurements of all traits were clearly positively associated with the herds of origin (b = 0.52-1.08). Animals with favourable phenotypic measurements originated from better herds. On the contrary, the predicted breeding values seemed to be independent of the herd effects (b= -0.16-0.08) and suggested a possible random distribution across the contemporary groups.

Full textAbstract:
An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production.

Purpose. To investigate the expression of TSP50 protein in human gastric cancers and its correlation with clinical/prognostic significance.Methods. Immunohistochemistry (IHC) analysis of TSP50 was performed on a tissue microarray (TMA) containing 334 primary gastric cancers. Western blot was carried out to confirm the expression of TSP50 in gastric cancers.Results. IHC analysis revealed high expression of TSP50 in 57.2% human gastric cancer samples (191 out of 334). However, it was poorly expressed in all of the 20 adjacent nontumor tissues. This was confirmed by western blot, which showed significantly higher levels of TSP50 expression in gastric cancer tissues than adjacent nontumor tissues. A significant association was found between high levels of TSP50 and clinicopathological characteristics including junior age at surgery (P=0.001), later TNM stage (P=0.000), and present lymph node metastases (P=0.003). The survival of gastric cancer patients with high expression of TSP50 was significantly shorter than that of the patients with low levels of TSP50 (P=0.021). Multivariate Cox regression analysis indicated that TSP50 overexpression was an independent prognostic factor for gastric cancer patients (P=0.017).Conclusions. Our data demonstrate that elevated TSP50 protein expression could be a potential predictor of poor prognosis in gastric cancer patients.

Full textAbstract:
Background: Laparoscopy is the best available tool and method to manage impalpable undescended testes; management of the impalpable testis often pose a significant diagnostic and therapeutic challenge to a surgeon. The aim of this work was to elucidate and present the sensitivity and the value of laparoscopy, as a surgeon’s tool, for the diagnosis and treatment of the impalpable testis.Methods: From November 2015 to December 2018, 56 patients with 60 impalpable testes were operated upon by laparoscopic approach by a single surgeon. One-stage Fowler-Stephens laparoscopic orchidopexy was performed in 14 cases, while two-stage Fowler-Stephens laparoscopic orchidopexy was performed in 16 cases and Vessel-Intact Laparoscopic Orchidopexy (VILO) was done in 22 cases. In 2 cases vessel and vas was entering through deep ring and inguinal orchidopexy was done. Blind ending vessel/vas was noticed in 4 cases (vanishing/absent testes). Laparoscopic orchidectomy was required in 2 patients for nubin. No case of disorder of sexual dysfunction was (DSD) was found.Results: Laparoscopy was successfully completed in all the cases. 34 testicles were impalpable on right side, 18 on left side and other 4 cases (8 testicles) were bilaterally impalpable. Laparoscopic orchidopexy was carried out for 36 testes at the same. 16 needed a staged procedure. Orchidectomy was done in 2 cases/testes. In 4 cases testes was absent/vanishing. In 2 cases testes was canalicular, standard inguinal orchidopexy was done. The mean operative time was 48 minutes. Patients were allowed oral fluids 6 hours of the operation and were discharged at one day after the procedure. None of the patients had wound infection. Patients were followed up for a mean period of 12 months. At follow-up, all but one of the testes were well down in the bottom of the scrotum. In one patient, the testis was in a high scrotal position. All testes were of normal size, no atrophy was seen so far and no malignant change is suspected in any case so far. No severe morbidity or death was observed in our study.Conclusions: Laparoscopy offers surgeons a safe and reliable diagnostic and therapeutic option to patients with impalpable testes. No other imaging investigation is required, if well versed with basic laparoscopy. Intra-abdominal dissection allows more testes to be brought down to the scrotum. Even when open orchidopexy is being done for intra-canalicular testes in a child, it is advisable to be ready with laparoscopy if necessary, at the same time, in case open surgery fails to mobilize the testicular vessels adequately. The procedure is best viewed as laparoscopy-assisted; as Orchidopexy has to be done in a conventional manner.

Abstract. Can experimental studies on the behavioural impacts of ocean acidification be trusted? That question was raised in early 2020 when a high-profile paper failed to corroborate previously observed responses of coral reef fish to high CO2. New information on the methodologies used in the “replicated” studies now provides a plausible explanation: the experimental conditions were substantially different. High sensitivity to test conditions is characteristic of ocean acidification research; such response variability shows that effects are complex, interacting with many other factors. Open-minded assessment of all research results, both negative and positive, remains the best way to develop process-based understanding. As in other fields, replication studies in ocean acidification are most likely to contribute to scientific advancement when carried out in a spirit of collaboration rather than confrontation.

<p>This research was carried out to investigate the genetic structure of the 20 F1s rapeseed hybrids established from five female moderate maturity lines and four early maturity male testers, to determine parents showing general combining ability (GCA) and detect crosses showing specific combining ability (SCA). Significant variance of parents and crosses for all the traits indicated the existence of significant genetic variation among the parents and their F1 cross combinations. Significant variance of parents <em>vs. </em>crosses revealed significant average heterosis for all the traits except first pod height and seeds per pod. High narrow-sense heritability estimates for number of branches and pods length, indicate the importance of additive genetic effects for these traits. Hybrid performance was generally better than parental performance for all the traits except number of branches and also the genetic variation of lines × testers for all the traits were more than lines and testers. Most of the crosses with high mean value of pods per plant were yielded from the parental lines with high mean value of this trait. The crosses including L41×Foma2, Zafar×R42 and L22B×R38 with significant positive SCA effects of seed yield had also high mean values (3400, 3311.3 and 2904.2 kg ha-1 , respectively) of this trait.</p>

 Abstract
 Among the vegetables grown, Lettuce (Lactuca sativa) stands out due to its source of vitamins B1, B2, C, iron and minerals, in addition to the availability of being grown in almost all regions of the globe. Given the above, the objective of the work was to evaluate, in a lettuce culture, the fresh mass of aerial part and fresh mass of the root with the application of the ZEBMAX®. The experiment was carried out in the field at the Colégio Agrícola de Toledo from June 10 to July 15, 2018. In the treatment, two doses of 0.5 ml L-1 were applied at 15 and 25 days after transplanting. In the witness, only water was used. A randomized block design in triplicate was used and a total of 10 plants per block were evaluated. The data were submitted to statistical analysis using the Tukey test, at the level of 5% probability. The treatment plants obtained a weight of fresh mass of aerial part of 12.55 g pl-1, with a fresh root mass of 10.88 g pl-1, while in the control the weight of fresh mass of aerial part was 11.08 g pl-1 with fresh root mass 9.44 g pl-1. Therefore, the present study showed significant differences for the growth variables (root and shoot), in relation to the application of ZEBMAX® as a source of fertilization, in the relationship between the treatment and the control.

Full textAbstract:
The aim of our study was to investigate the effect of caffeine supplementation on 3-min all-out arm crank exercise performance in paraplegic (P) and tetraplegic (T) compared with able-bodied (AB) participants. A placebo-controlled, randomized, crossover, and double-blind study design was chosen to investigate the differences between caffeine (CAF) and placebo (PLC). In total, 34 healthy, trained participants were tested. Seventeen were AB (median [minimum; maximum] VO2peak: 33.9 mL/min/kg [23.6; 57.6]), 10 were P (VO2peak: 34.4 mL/min/kg [19.5; 48.8]), and 7 were T (VO2peak: 13.6 mL/min/kg [8.6; 16.3]). All participants performed two 3-min all-out tests on an arm crank ergometer following the ingestion of either PLC or CAF. Power output parameters, plasma caffeine (PC), epinephrine (EPI), and norepinephrine (NOR) concentrations were assessed. CAF significantly increased average power over the first 30 s (p = .028) and 60 s (p = .005) in P, but not in T (p = .61; p = .87) nor in AB (p = .25; p = .44). Peak power was increased in the CAF trial in AB (+46 W) as well as in P (+21 W) but was not significantly different from PLC (AB: p = .10; P: p = .17). PC significantly increased in all groups (AB: p = .002; P: p = .005; T: p = .018) whereas EPI showed a significant increase only in AB (p = .002) and in P (p = .018). NOR increased significantly in AB (p = .018) but did not increase in the other groups. Caffeine seems to enhance short-duration exercise performance in P. In contrast, T showed a high interindividual variability and overall no ergogenic effect was detected in this group.

Understanding the ecological and epidemiological roles of pets in the transmission of SARS-CoV-2 is critical for animal and human health, identifying household reservoirs, and predicting the potential enzootic maintenance of the virus. We conducted a longitudinal household transmission study of 76 dogs and cats living with at least one SARS-CoV-2-infected human in Texas and found that 17 pets from 25.6% of 39 households met the national case definition for SARS-CoV-2 infections in animals. This includes three out of seventeen (17.6%) cats and one out of fifty-nine (1.7%) dogs that were positive by RT-PCR and sequencing, with the virus successfully isolated from the respiratory swabs of one cat and one dog. Whole-genome sequences of SARS-CoV-2 obtained from all four PCR-positive animals were unique variants grouping with genomes circulating among people with COVID-19 in Texas. Re-sampling showed persistence of viral RNA for at least 25 d-post initial test. Additionally, seven out of sixteen (43.8%) cats and seven out of fifty-nine (11.9%) dogs harbored SARS-CoV-2 neutralizing antibodies upon initial sampling, with relatively stable or increasing titers over the 2–3 months of follow-up and no evidence of seroreversion. The majority (82.4%) of infected pets were asymptomatic. ‘Reverse zoonotic’ transmission of SARS-CoV-2 from infected people to animals may occur more frequently than recognized.

Abstract Background South Carolina (SC) remains one of the most heavily affected states for both HIV and HCV infections. Males account for the majority of cases. Implementation of universal opt-out testing has improved screening rates but not much has been published describing the characteristics of those who opt out of testing. This becomes important as 10-50% of patients have opted out in previous studies. Methods Between February and August 2019, we conducted a quality improvement (QI) project which implemented opt- out HIV-HCV testing at a single primary care resident clinic in SC with the primary aim of increasing screening rates for HIV-HCV by 50%. Secondary aims included describing the demographic characteristics of the opt-out population. Persons were considered eligible for testing if they were between the ages of 18-65 years for HIV and 18-74 years for HCV. This was prior to the USPSTF 2020 guidelines which recommend HCV screening for adults aged 18-79 years. A retrospective chart review was used to obtain screening rates, opt status and demographic data. Logistic regression and the firth model were used to determine linkages between categorical variables. We present 3-month data. Results 1253 patients were seen between May 1, 2019- July 31, 2019 (See Table 1). 985 (78%) were eligible for HIV testing. 482 (49%) were tested for HIV as a result of our QI project and all tests were negative. 212 (22%) of eligible patients opted out of HIV testing. Males were 1.59 times more likely to opt out (p=0.008). (see Table 2,3) Regarding HCV, 1136 (90.7%) were deemed eligible for testing. 503 (44%) were tested for HCV as a result of our QI project. 12 (2.4%) were HCV antibody positive with viremia. 11 (90%) of antibody positive with viremia cases were in the 1945-1965 birth cohort (see Table 4). 244 (21%) opted out of HCV testing. Males and persons without a genitourinary chief complaint were more likely to opt out (p=0.02).

Logistic Model. Table 3: Relationship between demographic variables and the odds of opting out of testing for HIV or HCV. Firth Model. Conclusion Although implementation of routine HIV-HCV opt-out testing led to increased screening rates for both HIV and HCV, roughly 1 in 5 eligible patients chose to opt out of testing. Males were more likely to opt out despite accounting for the majority of newly diagnosed HCV cases. Future studies investigating drivers for opting-out in the male population could improve testing and assist with early diagnosis.

 1 RESUMO
 
 O objetivo do trabalho foi avaliar o efeito da porcentagem de área molhada (PW) na produtividade e relação hídrica na cultura da melancia (Citrullus lanatus). O experimento foi realizado no campo experimental da UFAL, Campus Arapiraca – UFAL. Os tratamentos foram em delineamento inteiramente casualizados, composto por gotejadores com duas vazões (1,39 L h-1 e 1,92 L h-1), sendo duas com linhas simples e duas com linhas duplas, totalizando quatro tratamentos (PW – 13, 14,25, 19 e 22%), com seis repetições. Foram feitas leituras com tensiômetros para monitorar o potencial de água no solo e termômetro de infravermelho para monitorar a temperatura na folha. Foram, ainda, avaliados índices fitotécnicos (teste de Tukey, 5%). Com base na análise dos resultados não foi observada diferenciação estatística para os atributos verificados, que foram eles: massa fresca, teor de sólidos solúveis, diâmetro e comprimento do fruto. As curvas de temperatura não indicaram estresse hídrico para nenhum tratamento. O T1 absorveu mais água em profundidade. Conclui-se que valores de PW abaixo do recomendado não afetam a produtividade da cultura da melancia e que a porcentagem de área molhada influencia as profundidades de absorção de água pela cultura.

 EFFECT OF FRACTING OF WET AREA BY DRIP IRRIGATION IN WATERMELON
 
 
 2 ABSTRACT
 
 The objective of this work was to evaluate the effect of PW on productivity and water relation on watermelon culture (Citrullus lanatus). The experiment was carried out in the experimental field of UFAL, Campus Arapiraca - UFAL. The missiles were completed in a randomized design, consisting of drippers with two flows (1.39 L h-1 and 1.92 L h-1), being twice and twice, totaling four treatments (PW - 13, 14, 25, 19 and 22 %), with six replicates. Tensiometers were read out to monitor soil water potential and the infrared thermometer to monitor the temperature on the sheet. Also, phytotechnical indexes were evaluated (Tukey's test, 5%). Based on the analysis of the results, a statistical comparison was not observed for the verified attributes, which were: fresh mass, soluble solids content, fruit diameter and length. As the temperature curves for both treatments are similar for all treatments. T1 absorbed more water in depth. It concludes that PW values below the recommended do not affect crop productivity and that the percentage of water is influenced as depths of water absorption by the crop.

Full textAbstract:
Monolithic aluminium has low density and high conductivity required in transmission conductors. However, it lacks the requisite strength necessary for long space crossing. To augment the strength, it needs to be reinforced with adequate materials. So, this work is focused on spark plasma sintering of Al-CNTs-Nb composite for power transmission conductor core. Spark plasma sintering of the samples was carried out with pre-determined optimum sintering parameters. After the sintering, the density of the sintered samples was calculated using Archimedes principle, while the micro hardness was tested with Vickers hardness tester. The polarisation test was carried out with Autolab (PGSTAT302N), while the electrical conductivity was tested with four-point probe meter. The results gave a 37% improvement in micro hardness and 30% increase in tensile strength with Al-8CNTs-1Nb. Al-1CNTs-4Nb gave the best corrosion characteristics of 51% and 57% improvements in corrosion rates and 443% and 323% improvements in polarisation resistance in NaCl and H2SO4 media, respectively. Electrical conductivity showed a little increase by 2%. In all, it is evident that this composite is a suitable material for power transmission conductor core for upgrading the power grid.

Full textAbstract:
On the basis of three examples the results of P-value determinations are presented in connection with the results of integrative test methods: food preference test with laboratory rats, sensory evaluations with consumers and self-decomposition tests. In all three cases a corresponding evidence regarding the relevant data as well as the differentiating factors fertiliser and/or cultivation systems could be demonstrated. In food preference tests with laboratory rats organically grown carrots (Tarvil cultivar) and beet roots (Formanova cultivar) were significantly preferred to the respective conventionally produced variants. The determination of electro-chemical parameters of these test products was carried out by R. Krautgartner at the Institute of Fruit Growing and Horticulture, University of Agricultural Sciences in Vienna. The P-values were lower in the organic products, thus indicating better quality. Sensory tests were applied to investigate the taste of differentlyk fertilised apples (Golden Delicious cultivar). The samples originated from a field trial at the Research Institute for Fruit Growing and Viticulture in Haidegg (Styria). In this case the lower P-values (measured by H. Keppel), the preference and the application of the organic fertiliser Agrobiosol, which has a favourable effect on soil microorganisms, were in keeping as well. A series of self-decomposition tests was carried out with spinach samples (Spinnaker F1 cultivar) from a field trial in Gerasdorf near Vienna (R. Krautgartner, Institute of Fruit Growing and Horticulture, University of Agricultural Sciences in Vienna), investigating the influence of 5 different fertilisers on product quality. The ranging of the samples according to the loss of dry matter during self-decomposition corresponded with the electro-chemical ranging: lower P-values, lower dry matter loss and a longer shelf life were found in the organically fertilised samples. The here presented concurring data obtained from different integrative quality tests in connection with cultivation methods clearly indicate the advantage and the value of multiperspective research projects. &nbsp;

 Abstract
 This work aimed to identify and evaluate the environmental and microbiological quality of springs present in the urban area of Santo Antônio do Monte -Minas Gerais. The environmental impacts on the springs were assessed based on the interpretation of the Environmental Impact Index on Springs - IIAN. The microbiological analysis of the water was performed using the Chromogenic Substrate Test (Colitest®), which shows either the presence or absence of total and thermotolerant coliforms. Fourteen springs were identified, but in four of them, the application of the test was not possible (springs 11, 12, 13 and 14), as they were dry, buried or taken over by sewage discharge. Out of the springs evaluated, none reached a classification of "Excellent" (Class A) or "Good" (Class B). Only one was classified as "Reasonable" (Source 1; Class C), five as "Bad" (Source 2, 3, 6, 7 and 8, Class D) and four as "Terrible" (Source 4, 5, 9 and 10, Class E). All the springs showed positive results for the presence of total and thermotolerant coliforms (Escherichia coli).

Assim, este trabalho analisa o comportamento espacial e a estabilidade temporal do armazenamento de água no solo, a fim de determinar pontos da área que possam representar o valor médio espacial da umidade. O trabalho foi realizado numa área com solo predominantemente arenoso (Neossolo Quartizarênico), cultivado com videira e irrigado por microaspersão, em Petrolina-PE. O monitoramento da água no solo foi realizado por tensiometria. As análises estatísticas e geoestatísticas foram realizadas pelos softwares Statistica Development Environment, GS+ e GeoR. As técnicas sugeridas por Vachaud et al. (1985) e Kachanoski e De Jong (1988) foram usadas para avaliar a estabilidade temporal da água no solo, ao longo do tempo. A geoestatística foi adequada para descrever a estrutura de dependência espacial do armazenamento de água no solo e, para algumas datas, estabilidade temporal foi boa, em todos os pontos (39) monitorados na área. Para a camada de 0-20 cm, os pontos 32 e 10 foram os mais indicados como representativos da média espacial do armazenamento de água no solo; já para a camada de 20-40 cm foi o ponto 37 que melhor representou a média espacial. Logo, esses pontos (10, 32 e 37) são os melhores representantes para realização de uma amostragem de água no solo; além disso, esses pontos, poderiam ser utilizados para o monitoramento, para fins de manejo de irrigação. A variabilidade espacial da água no solo mostra a importância do manejo diferenciado da irrigação, considerando-se as diferentes zonas do solo e não a área como sendo homogênea (como é feito na atualidade).

A. deSPATIAL VARIABILITY AND TIME STABILITY OF WATER STORED IN A SANDY SOIL CULTIVATED WITH IRRIGATED VINES 2 ABSTRACT The water spatiotemporal behavior in soil is crucial for precise irrigation management. This work analyzes the spatial behavior and the temporal stability of water storage in the soil, in order to determine points of the area that can represent the spatial average value of moisture. The study was conducted in an area with predominantly sandy soil (Quartzarenic Neosol), cultivated with vine and micro sprinkler irrigation system in Petrolina. Monitoring soil water was carried out by tensiometry. Statistical analysis and geostatistical were performed by Statistica software development environment, GS + and GeoR. The techniques suggested by Vachaud et al. (1985) and Kachanoski and De Jong (1988) were used to evaluate the temporal stability of the water in the soil over time. Geostatistics was adequate to describe the spatial dependence structure of water storage in the soil and, for certain dates, temporal stability was good in all points (39) in the monitored area. For 0-20 cm, paragraphs 32 and 10 were the most indicated as representative of the spatial average water storage in the soil; already for the 20-40 cm layer was point 37 that best represented the spatial average. Therefore, these points (10, 32 and 37) are the best representatives for the realization of a water sampling in soil; In addition, these points could be used for monitoring for the irrigation purposes. The spatial variability of soil water shows the importance of different irrigation management, considering the different soil zones and not the area to be homogeneous (as is done today).
