Abstract:
Since long-term weight maintenance (WM) is a major problem, interventions to improve WM are needed. The aim of the study was to investigate whether the addition of protein to the diet might limit weight regain after a weight loss of 5–10 % in overweight subjects. In a randomised parallel study design, 113 overweight subjects (BMI 29·3 (SD 2·5) kg/m2); age 45·1 (SD 10·4) years) followed a very-low-energy diet for 4 weeks, after which there was a 6-month period of WM. During WM, subjects were randomised into either a protein group or a control group. The protein group received 30 g/d protein in addition to their own usual diet. During the very-low-energy diet, no differences were observed between the groups. During WM, the protein group showed a higher protein intake (18 %v.15 %;P<0·05), a lower weight regain (0·8v.3·0 kg;P<0·05), a decreased waist circumference (−1·2 (SD 0·7)v.0·5 (SD 0·5 ) cm;P<0·05) and a smaller increase in respiratory quotient (0·03 (SD 0·01)v.0·07 0·01; (SD/)P<0·05) compared with the control group. Weight regain in the protein group consisted of only fat-free mass, whereas the control group gained fat mass as well. Satiety in the fasted state before breakfast increased significantly more in the protein group than in the control group. After 6 months follow-up, body weight showed a significant group × time interaction. A protein intake of 18 % compared with 15 % resulted in improved WM in overweight subjects after a weight loss of 7·5 %. This improved WM implied several factors, i.e. improved body composition, fat distribution, substrate oxidation and satiety.

Abstract:
Objective: To evaluate intermittent Kangaroo Mother Care (KMC) with additional opportunities to breastfeed on weight gain of low birth weight (LBW) neonates with delayed weight gain. Methods: 40 LBW neonates were followed to see whether KMC with additional opportunities to breastfeed improved weight gain. Results: In the KMC group, the mean age of regaining birth weight was significantly less (15.68 vs. 24.56 days) and the average daily weight gain was significantly higher (22.09 vs. 10.39 g, p < .001) than controls. Conclusion: KMC with additional opportunities to breastfeed was found to be an effective intervention for LBWs with delayed weight gain and should be considered to be an effective strategy.

Abstract:
Jockeys are required to maintain very low body weight and precise weight control during competition. This study examined the weight loss and weight management strategies of professional horseracing jockeys in the state of Victoria, Australia. An anonymous, self-completed questionnaire was administered (55% response rate, n=116). Almost half (43%) reported that maintaining riding weight was difficult or very difficult, with 75% routinely skipping meals. In preparation for racing, 60% reported that they typically required additional weight loss, with 81% restricting food intake in the 24 hours prior to racing. Additionally, sauna-induced sweating (29%) and diuretics (22%) were frequently employed to further aid in weight loss prior to racing. These rapid weight loss methods did not differ between the 51% of jockeys who followed a weight management plan compared to those who did not. The impact of these extreme weight loss practices on riding performance and health remains unknown.

Abstract:
The aim of this Master's study was to quantify the effect of adding weight to the trunk on posture-movement adaptations in healthy young adults during repetitive arm motion-induced fatigue. Whole- body kinematic, kinetic and electromyographic (EMG) data were recorded during a repetitive pointing task (RPT) in normal conditions and with a 20% body weight extra load. The first and last minutes of the RPT were analyzed for both sessions. Results show that the RPT was effective in inducing muscular fatigue in three of the four upper limb muscles investigated. Other results of this study confirm the ability of the body system to adapt to fatigue in different postural conditions. A few different adaptations to fatigue were selected by the system in the added weight condition to contribute to the performance of the task and reach a similar time to fatigue as in normal condition. Results suggest that adaptations to fatigue in the extra weight condition could aim at ensuring postural stability by maintaining the body's center of mass stable, in addition to reducing the load of the fatigued musculature.<br>L'objectif de cette étude de maitrise était de quantifier les effets d'ajouter du poids sur le tronc corporel sur les adaptations de la posture et du mouvement de jeunes adultes en santé durant la fatigue induite par des mouvements répétitifs du bras. Des données cinématiques, cinétiques et électromyographiques (EMG) ont été enregistrées durant une tâche de pointage répétitif (TPR) en condition normale et avec une charge additionnelle de 20% du poids corporel. Les premières et dernières minutes de la TRP ont été analysées pour les deux séances. Les résultats démontrent que la TRP a été efficace à induire de la fatigue musculaire à trois des quatre muscles du membre supérieur. Les autres résultats de cette étude confirment la capacité du système corporel à s'adapter à la fatigue dans différentes conditions posturales. Quelques adaptations différentes à la fatigue ont été sélectionnées par le système dans la condition de charge additionnelle afin de contribuer à la performance de la tâche et d'atteindre un temps total de tâche similaire à celui en condition normale. Les résultats suggèrent que les adaptations à la fatigue et à la charge additionnelle pourraient viser à assurer la stabilité posturale en maintenant un centre de masse corporel stable tout en réduisant la charge sur les muscles fatigués.

No. of bitstreams: 1 3650.pdf: 2665411 bytes, checksum: a3e1a670598c88e67fcd991608db14b7 (MD5) Previous issue date: 2011-02-18<br>Financiadora de Estudos e Projetos<br>Reaching behavior is an important motor skill because its emergence is one of the first phases of the voluntary motor development during childhood. However, few studies have shown how intrinsic (such as prematurity) and extrinsic factors (such as additional weight) influence this ability. Objectives: This study has as main objectives: 1) to analyze the development of categorical reach variables in preterm and full-term infants, 2) to verify the effect of additional weight attached on the wrists of preterm infants, 3) to verify the need for age correction in the reach of preterm infants. Methods: This study evaluated longitudinally 9 preterm infants aged 5-7 month with mean gestational age of 35.6 (± 0.5) weeks and 10 full-term infants with mean gestational age of 39 (± 0.73) weeks. Both groups had normal birthweight and Apgar score above 7 in the first and fifth minutes. Categorical and kinematic reach variables were analyzed. The categorical variables analyzed were: a) proximal adjustments: unimanual and bimanual b) distal adjustments: hand orientation (vertical, horizontal or oblique), hand classification (open, closed and semi-open), c) grasping: successful and unsuccessful grasping. The kinematic variables measured were: a) mean velocity (MV): ratio between distance traveled and time spent in movement b) movement unit (MU): phase of acceleration and deceleration of the movement during the trajectory; straightness index (SI): ratio between the distance traveled by the hand and the smallest distance that could be traveled on this path. To meet the objectives, three studies were developed for this PhD thesis. Results: Study I was aimed at investigating the development of proximal and distal adjustments of the reach of low-risk pre-term infants in the age group of 5-7 months. The categorical reach variables were analyzed. It was observed that the unimanual reach frequency was greater than the bimanual reach throughout the study period, with no difference between ages in both groups; the frequency of vertical orientation of the hand increased significantly from the 6th to the 7th month in the preterm group and from the 5th to the 7th month in the full-term group; the increased frequency of open hand and decreased frequency of semi-open hand were significant from the 5th to the 7th month in the preterm and full-term groups; the frequency of successful grasp increased from the 6th to the 7th month in preterm and full-term groups. A higher frequency of open hand was found in the preterm group at the 6th month compared to the full-term group between groups. Study II aimed to determine the influence of additional weight and its immediate removal on the reaching of low-risk preterm infants at the age group from 5 to 7 months. The kinematic variables and the grasping were analyzed. It was found that additional weight has reduced the straightness index at the age of five months, increased the mean velocity and decreased the movement units in all age groups and increased the frequency of reaches without grasp at 5 and 7 months. The post-weight reduced the straightness index at the age of 5 months and increased the movement units at 6 and 7 months. Finally, study III aimed to assess the reach of low-risk preterm infants at corrected and chronological ages in order to determine the need for age correction to evaluate the reaching behavior. Comparing the preterm group with chronological age with the full-term group, the former had lower speed, more movement units, hand more horizontal and higher frequency of unsuccessful grasp at 7 months of age. In the pre-corrected age, preterm infants showed lower speed than the full-term group, but with successful grasping. Conclusions: considering the intrinsic restriction imposed by prematurity (considering the corrected age of preterm infants), it seems that it was not enough to prevent the performance of the reaching task in the age group studied. When checking the extrinsic restriction caused by additional weight, it was found that it significantly influenced the reach parameters of preterm infants and these results could support future researches aimed at intervention techniques with the use of additional weight in infants at risk.<br>O alcance manual é uma importante habilidade motora, pois sua emergência é uma das primeiras fases do desenvolvimento motor voluntário durante a infância. No entanto, poucos estudos são encontrados demonstrando como os fatores intrínsecos (como a prematuridade) e extrínsecos (como o peso adicional) influenciam esta habilidade. Objetivos: Desta forma, o presente estudo tem como objetivos principais: 1) analisar o desenvolvimento das variáveis categóricas do alcance em lactentes pré-termo e a termo; 2) verificar o efeito do peso adicional nos punhos dos lactentes pré-termo; 3) verificar a necessidade da correção da idade no alcance em lactentes pré-termo. Métodos: Para tanto foram avaliados longitudinalmente, na faixa etária de 5 a 7 meses, 9 lactentes pré-termo, com idade gestacional média de 35,6 (±0,5) semanas e 10 lactentes a termo, com idade gestacional média de 39 (±0,73) semanas. Ambos os grupos apresentaram peso adequado ao nascer e Apgar superior a 7 no 1o e 5o minutos. Foram analisadas variáveis categóricas e cinemáticas do alcance. As variáveis categóricas analisadas foram: a) ajustes proximais: unimanual e bimanual; b) ajustes distais: orientação da mão (verticalizada, horizontalizada e obliqua), classificação da mão (aberta, fechada e semi-aberta); c) preensão: preensão com sucesso e sem sucesso. As variáveis cinemáticas avaliadas foram: a) velocidade média (VM): razão entre distância percorrida e tempo gasto no movimento; b) unidade de movimento (UM): fase de aceleração e desaceleração do movimento durante a trajetória; índice de retidão (IR): razão entre a distância percorrida pela mão e a menor distância que poderia ser percorrida nesta trajetória. Para atender os objetivos, três estudos foram desenvolvidos para esta tese de doutorado. Resultados: O Estudo I teve como objetivo investigar o desenvolvimento de ajustes proximais e distais do alcance de lactentes pré-termo de baixo risco na faixa etária de 5 a 7 meses de vida. Foram analisadas as variáveis categóricas do alcance. Foi observado que a freqüência de alcances unimanuais foi maior que bimanuais durante todo o período analisado, sem nenhuma diferença entre as idades em ambos os grupos; a freqüência de orientação vertical da mão aumentou significativamente do 6º para o 7º mês no grupo pré-termo e do 5º para o 7º mês no grupo a termo; o aumento da freqüência de mão aberta e diminuição de semi-aberta foram significativos do 5º para o 7º mês no grupo pré-termo e a termo; a freqüência de preensão com sucesso aumentou do 6º para o 7º mês no grupo pré-termo e a termo. Entre os grupos foi encontrado uma maior freqüência de mão aberta no grupo pré-termo aos 6 meses quando comparado ao a termo. O Estudo II teve como objetivo verificar a influência do peso adicional e a sua retirada imediata no alcance manual de lactentes pré-termo de baixo risco, na faixa etária de 5 a 7 meses de idade. Foram analisadas as variáveis cinemáticas e a preensão do alcance. Constatouse que o peso adicional diminuiu o índice de retidão aos 5 meses, aumentou a velocidade média e diminuiu as unidades de movimento em todas as idades e aumentou a freqüência de alcances sem preensão aos 5 e 7 meses. O pós-peso levou a diminuição do índice de retidão aos 5 meses e aumento das unidades de movimento aos 6 e 7 meses. E finalmente, o Estudo III que teve como objetivo avaliar o alcance de lactentes pré-termo de baixo risco nas idades cronológica e corrigida, com o intuito de determinar a necessidade da correção da idade ao se avaliar o alcance manual. Comparando-se o grupo pré-termo com idade cronológica com o grupo a termo, os primeiros apresentaram menor velocidade, mais unidades de movimento, mão mais horizontalizada e com maior freqüência de preensão sem sucesso aos 7 meses. Na idade corrigida os pré-temo apresentaram velocidade menor que o a termo, porém manteve a preensão com sucesso. Conclusões: Referente à restrição intrínseca imposta pela prematuridade (ao considerar a idade corrigida dos lactentes pré-termo) parece que esta não foi suficiente para impedir a performance da tarefa do alcance na faixa etária estudada. Ao verificar a restrição extrínseca causada pelo peso adicional, observou-se que esta influenciou significativamente os parâmetros do alcance de lactentes pré-termo e tais resultados poderão subsidiar futuras pesquisas objetivando técnicas de intervenção com o uso do peso adicional em lactentes de risco.

Abstract:
Doctor of Philosophy (PhD), Engineerig<br>Free radical emulsion polymerization (FRP) is widely adopted in industry due to its applicability to a wide range of monomers. Despite its many benefits and wide spread use, the fast chain growth and the presence of rapid irreversible termination impose limitations with respect to the degree of control in FRP. Furthermore, producing block copolymers and polymers with complex structures via FRP is not feasible. Closer control of macromolecular chain structure and molar mass, using novel polymerization techniques, is required to synthesize and optimize many new polymer products. Reversible addition fragmentation chain transfer (RAFT)-mediated polymerization is a novel controlled living free radical technique used to impart living characters in free radical polymerization. In combination with emulsion polymerization, the process is industrially promising and attractive for the production of tailored polymeric products. It allows for the production of particles with specially-tailored properties, including size, composition, morphology, and molecular weights. The mechanism of RAFT process and the effect of participating groups were discussed with reviews on the previous work on rate retardation. A mathematical model accounting for the effect of concentrations of propagating, intermediate, dormant and dead chains was developed based on their reaction pathways. The model was combined with a chain-length dependent termination model in order to account for the decreased termination rate. The model was validated against experimental data for solution and bulk polymerizations of styrene. The role of the intermediate radical and the effect of RAFT agent on the chain length dependent termination rate were addressed theoretically. The developed kinetic model was used with validated kinetic parameters to assess the observed retardation in solution polymerization of styrene with high active RAFT agent (cumyl dithiobenzoate). The fragmentation rate coefficient was used as a model parameter, and a value equal to 6×104 s-1 was found to provide a good agreement with the experimental data. The model predictions indicated that the observed retardation could be attributed to the cross termination of the intermediate radical and, to some extent, to the RAFT effect on increasing the average termination rate coefficient. The model predictions showed that to preserve the living nature of RAFT polymerization, a low initiator concentration is recommended. In line with the experimental data, model simulations revealed that the intermediate radical prefers fragmentation in the direction of the reactant. The application of RAFT process has also been extended to emulsion polymerization of styrene. A comprehensive dynamic model for batch and semi-batch emulsion polymerizations with a reversible addition-fragmentation chain transfer process was developed. To account for the integration of the RAFT process, new modifications were added to the kinetics of zero-one emulsion polymerization. The developed model was designed to predict key polymer properties such as: average particle size, conversion, particle size distribution (PSD), and molecular weight distribution (MWD) and its averages. The model was checked for emulsion polymerization processes of styrene with O-ethylxanthyl ethyl propionate as a RAFT based transfer agent. By using the model to investigate the effect of RAFT agent on the polymerization attributes, it was found that the rate of polymerization and the average size of the latex particles decreased with increasing amount of RAFT agent. It was also found that the molecular weight distribution could be controlled, as it is strongly influenced by the presence of the RAFT based transfer agent. The effects of RAFT agent, surfactant (SDS), initiator (KPS) and temperature were further investigated under semi-batch conditions. Monomer conversion, MWD and PSD were found to be strongly affected by monomer feed rate. With semi-batch mode, Mn and <r> increased with increasing monomer flow rate. Initiator concentration had a significant effect on PSD. The results suggest that living polymerization can be approached by operating under semi-batch conditions where a linear growth of polymer molecular weight with conversion was obtained. The lack of online instrumentation was the main reason for developing our calorimetry-based soft-sensor. The rate of polymerization, which is proportional to the heat of reaction, was estimated and integrated to obtain the overall monomer conversion. The calorimetric model developed was found to be capable of estimating polymer molecular weight via simultaneous estimation of monomer and RAFT agent concentrations. The model was validated with batch and semi-batch emulsion polymerization of styrene with and without RAFT agent. The results show good agreement between measured conversion profiles by calorimetry with those measured by the gravimetric technique. Additionally, the number average molecular weight results measured by SEC (GPC) with double detections compare well with those calculated by the calorimetric model. Application of the offline dynamic optimisation to the emulsion polymerization process of styrene was investigated for the PSD, MWD and monomer conversion. The optimal profiles obtained were then validated experimentally and a good agreement was obtained. The gained knowledge has been further applied to produce polymeric particles containing block copolymers. First, methyl acrylate, butyl acrylate and styrene were polymerized separately to produce the first block. Subsequently, the produced homopolymer attached with xanthate was chain-extended with another monomer to produce block copolymer under batch conditions. Due to the formation of new particles during the second stage batch polymerization, homopolymer was formed and the block copolymer produced was not of high purity. The process was further optimized by operating under semi-batch conditions. The choice of block sequence was found to be important in reducing the influence of terminated chains on the distributions of polymer obtained. It has been found that polymerizing styrene first followed by the high active acrylate monomers resulted in purer block copolymer with low polydispersity confirmed by GPC and H-NMR analysis.

Abstract:
La thèse porte sur la caractérisation expérimentale des pertes singulières dans les matériaux magnétiques au sein d’actionneurs électromécaniques conçus pour le développement du programme « avion plus électrique », où la maîtrise des pertes d’énergie est un enjeu absolument majeur. Ce programme, de portée mondiale, vise, entre autre, à remplacer, dans l’avion, les actionneurs hydrauliques par des actionneurs électromécaniques, quand c’est possible.Par pertes singulières on entend toutes les pertes liées aux contraintes magnéto-mécano-thermiques liées d’une part à la mise en œuvre (découpe, assemblage contraint, isolation, traitement thermique...) des matériaux et d’autre part aux conditions réelles de fonctionnement (champ tournant, haute fréquence, saturations locales...) au sein des machines électriques (HV/HF), et qui sont très difficiles à estimer précisément de façon analytique ou via les dispositifs conventionnels de tests. Ces sollicitations influencent les caractéristiques de tôles qui peuvent s’éloigner significativement des données du fabricant (donc fausser le calcul des performances).Au début de cette thèse on s’est focalisé sur le montage d’un banc d’essai évolutif équipé de moyens de mesure directe du couple et d’une machine d’entraînement (8 ktr/min ; 42 kW) tarée par nos soins. Sur cette dernière une longue campagne d’essais a été menée pour isoler les différentes composantes de pertes, dont, par exemple, les pertes mécaniques (par frottement dans les roulements + aérodynamiques) qui ont été quantifiées via un rotor neutre. Les pertes dans les aimants sont indissociables des pertes fer, donc, elles ont été estimées par le biais d’une modélisation par éléments finis tridimensionnelle. Les pertes dans la frette de maintien sont nulles du fait qu’elle est isolante (thermo-rétractable). Le bobinage utilisé dans ce moteur est très particulier, à barres massives (remplissage de cuivre dans l’encoche jusqu’à 90%), développé dans notre laboratoire IES. Les pertes atypiques au sein de ce bobinage spécial ont été profondément abordées dans ces travaux (effet de refoulement de courants, pertes aux extrémités de la machine...).Dans la dernière partie de cette thèse, nous avons exploré le fonctionnement des machines synchrones à aimants à haute fréquence afin d’accroître la densité de puissance de nos moteurs (pour franchir la barre de 2.5 kW/kg). Pour ce faire, après une étude détaillée, nous avons proposé en premier lieu un prototype avec des matériaux standard (stator FeCo Vacodur49 0.2mm, rotor FeSi, aimants NdFeB nuance N35EH, bobinage à barres cuivre) fonctionnant à 1666 Hz, tournant à 5000 tr/min, avec une densité de puissance de 4.5 kW/kg et un rendement de 94%. En second lieu, nous avons proposé un deuxième prototype de rendement plus faible (93%) mais qui a une densité de puissance proche de 6 kW/kg avec un rotor sans fer et un bobinage en Aluminium.Avant le montage final de ce prototype modulaire, nous avons effectué des mesures de pertes magnétiques, en conditions réelles de fonctionnement d’un moteur électrique, sur une multitude de tôles FeSi et FeCo (Vacodur49, NO20, M270-35A) avec la variation de différents procédés de fabrication: isolation (vernis thermo-collant « back-lack », vernis C5), découpe (laser, électroérosion) et traitement thermique. Pareillement, toutes les pertes mises en jeu ont été séparées (mécaniques, par courants induits dans les viroles...) pour pouvoir remonter aux pertes magnétiques et, donc, enfin, quantifier empiriquement le coefficient de majoration de pertes fer<br>The main aim of this thesis was to study and experimentally assess the additional iron losses in the stator (electrical lamination steel) of high performance permanent magnet synchronous machines (PMSM) designed for aircraft applications, in relation with the “more-electric-aircraft” project. This international program consists of gradually introducing electrical systems to replace onboard hydraulic and pneumatic systems, for example to power the landing gear wheels (Electric Green Taxiing System)…The extra iron losses are caused by manufacturing processes (cutting, sticking, insulation, stacking, pressing, shrink-fitting, thermal treatment …) and the real conditions of use of electrical motor (namely: rotational flux, saturation, high frequency…). Indeed, the mechanical and thermal stresses during the manufacturing steps can deteriorate the magnetic properties of the material and significantly increase the iron losses. These aspects are difficult to accurately evaluate by analytical models or standard measurements (Epstein frame…) and require experimental assessment to precisely calculate the motor efficiency.First of all, we started by developing a test bench equipped with drive motor: PMSM 8000 RPM ; 42 kW. For accurate assessment, the losses in this machine are separated on the test bench, for example, the mechanical losses (bearings loss &amp; windage loss) have been measured at different speed with a non-magnetic rotor. Rotor magnets eddy-current losses cannot be isolated from iron losses, for this reason they have been calculated using a 3D finite element model. To limit rotor loss we then used a non-conductive retaining sleeve (heat shrink sleeve). In the winding, we used bar-wound conductors, which is an original winding technology developed in our laboratory, and whose advantage among others is the unusual copper fill factor that reaches almost 90%.Subsequently, we explored the high frequency machines (&gt;1 kHz) in order to increase the power-to-weight ratio (cross the threshold of 2.5 kW/kg). We proposed, the following to the analytical and finite element study, a first conventional prototype with a power-to-weight ratio equal to 4.5 kW/kg with: FeCo stator (Vacodur49 0.2 mm), FeSi rotor and NdFeB magnets (N35EH), operated at 1666 Hz, 5000 RPM and 94% efficiency at full load. A second motor had been also proposed with both rotor and winding in aluminum, in this case the power-to-weight ratio reaches around 6 kW with, however, less efficiency (93%).Finally, this HF motor was tested, at no load, on the aforementioned test bench. The experiments were carried out on a multitude of FeCo and FeSi stator core samples coming from different manufacturing processes (insulation: bonding varnish and C-5 varnish; cutting: laser and EDM “Electrical Discharge Machining”; thermal treatment) in real operating conditions of a high frequency PM machine in order to experimentally obtain the famous “additional coefficient” of iron losses (Kadd)

Thesis (MNutr)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: The role of fructose restriction in addition to dietary modifications for weight loss and lifestyle improvement, on fertility outcome and other markers of metabolic syndrome, in obese women with polycystic ovarian syndrome (PCOS) Introduction: At the time at which the current study was undertaken no data, as yet, existed on whether restriction of fructose, while treating obese patients with PCOS for weight loss, improves the clinical symptoms and metabolic/anthropometric profile so as to promote fertility. Objectives: To evaluate the baseline intake of fructose, as well as the effect of restricting fructose intake from fruit and soft beverages to less than 20 g daily, as well as to provide guidelines for weight loss on anthropometric measurements, for improving subjective clinical symptoms, and for promoting fertility outcome in obese patients with PCOS, who seek to become fertile. Methods: The study was conducted in the Tygerberg Hospital Infertility Clinic, as an experimental cohort. Patients with a body mass index (BMI) higher than 27, seeking fertility after diagnosis with PCOS, were referred for dietary consultation, and followed up 3 monthly over 1 year. At each visit anthropometric measurements and a detailed dietary history were taken and a questionnaire for clinical symptoms was completed. Results: Baselinely, 86 patients were included in the study. Averages for weight and BMI were 99.8 ± 24.3 kg and 39.2 ± 8.7kg/m2, respectively. Average baseline daily fructose intake was 167 ± 116.8g. At baseline, significant relationships were shown between fructose intake and burning feet (ρ=0.02) and frequent waking (ρ=0.02), with a trend towards nightly eating (ρ=0.07). The dropout rate after visit 1 was 50%, with a further dropout of 41% after visit 2. After 3 visits (n=18), fructose intake significantly reduced (ρ=0.018), with the significant relationships with clinical symptoms having disappeared by visit 2. After 3 visits (n=18), both weight and BMI decreased significantly (ρ=0.017) and (ρ=0.019), respectively. Fructose was tested as a covariate to BMI, with high significance (ρ=0.006) in said population group. Conclusion: Dietary intervention to reduce fructose intake proved significant for weight loss and BMI after 3 visits. Reduced fructose intake was associated with reduced clinical symptoms. With fructose being a significant covariate to BMI, it can be concluded that fructose overconsumption could possibly contribute to both clinical symptoms and elevated BMI in said study population.<br>AFRIKAANSE OPSOMMING: Die rol wat die beperking van fruktose speel bykomend tot dieetaanpassings en lewenstylverbetering vir gewigsverlies by oorgewig vroue met polisistiese ovariële sindroom (PCOS) in die uitkoms van fertiliteit en ander merkers van metaboliese sindroom. Inleiding: Met die aanvang van hierdie studie was daar is geen data beskikbaar oor die invloed van die beperking van fruktose in die dieet van oorgewig pasiënte met PCOS wat vir gewigsverlies behandel word nie. Dit was ook nie bekend of laasgenoemde pasiënte se kliniese simptome en metaboliese/antropometriese profiel sou verbeter met die beperking van fruktose sodat fertiliteit by hierdie pasiënte terselfdertyd ook bevorder word nie. Doelwitte: Die evaluering van die aanvanklike inname van fruktose, sowel as die beperking van fruktose afkomstig van eetbare vrugte en versoete drankies en sap tot ’n inname van minder as 20 g daagliks, tesame met riglyne vir gewigsverlies. Die uitkoms hiervan is bepaal deur antropometriese metings, die verbetering in subjektiewe kliniese simptome en die fertiliteituitkoms by oorgewig pasiënte wat hulp met fertiliteit verlang. Metodes: Die studie het as ’n eksperimentele kohort by die Infertiliteitskliniek by Tygerberg Hospitaal plaasgevind. Pasiënte wat na diagnose met PCOS fertiliteitsbehandeling verlang het en ’n BMI hoër as 27 gehad het , is vir dieetbehandeling verwys en driemaandeliks oor ’n tydperk van een jaar opgevolg. Tydens elke besoek is antropometriese metings en ’n omvattende dieetgeskiedenis geneem en ’n vraelys oor kliniese simptome ingevul. Resultate: Aanvanklik is 86 pasiënte by die studie ingesluit. Gemiddeldes vir gewig en BMI was 99.8 ± 24.3 kg en 39.2 ± 8.7 kg/m2 respektiewelik. Gemiddelde aanvanklike daaglikse inname van fruktose was 167 ± 116.8 g. Oorspronklik het betekenisvolle verhoudings tussen fruktose en die volgende bestaan: brandvoete (ρ=0.02) en veelvuldige episodes van nagtelike wakkerheid (ρ=0.02), met ’n neiging na nagtelike etery (ρ=0.07). Die uitvalsyfer na een besoek was 50% met ’n verdere uitvalsyfer van 41% na die tweede besoek. Na drie besoeke (n=18) het sowel die gewig as die BMI betekenisvolle afname getoon (ρ= 0.017) en (ρ=0.019), respektiewelik. Fruktose is as ’n belangrike kovariant vir BMI (ρ= 0.006) vir hierdie populasiegroep geïdentifiseer. Gevolgtrekking: Dieetintervensie vir die vermindering van die inname van fruktose was beduidend vir gewigsverlies en afname in BMI na drie besoeke. Verminderde fruktose-inname het gelei tot die vermindering van kliniese simptome. Met fruktose as beduidende kovariant vir BMI kan die gevolgtrekking gemaak word dat die oor-inname van fruktose by hierdie studiepopulasie waarskynlik tot sowel kliniese simptome as BMI bygedra het.

Abstract:
Doutoramento em Bioquímica<br>Os polissacarídeos são os componentes maioritários dos grãos de café verde e torrado e da bebida de café. Os mais abundantes são as galactomananas, seguindo-se as arabinogalactanas. Durante o processo de torra, as galactomananas e arabinogalactanas sofrem modificações estruturais, as quais estão longe de estar completamente elucidadas devido à sua diversidade e à complexidade estrutural dos compostos formados. Durante o processo de torra, as galactomananas e arabinogalactanas reagem com proteínas, ácidos clorogénicos e sacarose, originando compostos castanhos de alto peso molecular contendo nitrogénio, designados de melanoidinas. As melanoidinas do café apresentam diversas atividades biológicas e efeitos benéficos para a saúde. No entanto, a sua estrutura exata e os mecanismos envolvidos na sua formação permanecem desconhecidos, bem como a relação estrutura-atividade biológica. A utilização de sistemas modelo e a análise por espectrometria de massa permitem obter uma visão global e, simultaneamente, detalhada das modificações estruturais nos polissacarídeos do café promovidas pela torra, contribuindo para a elucidação das estruturas e mecanismos de formação das melanoidinas. Com base nesta tese, oligossacarídeos estruturalmente relacionados com a cadeia principal das galactomananas, (β1→4)-Dmanotriose (Man3), e as cadeias laterais das arabinogalactanas, (α1→5)-Larabinotriose (Ara3), isoladamente ou em misturas com ácido 5-Ocafeoilquínico (5-CQA), o ácido clorogénico mais abundante nos grãos de café verde, e péptidos compostos por tirosina e leucina, usados como modelos das proteínas, foram sujeitos a tratamento térmico a seco, mimetizando o processo de torra. A oxidação induzida por radicais hidroxilo (HO•) foi também estudada, uma vez que estes radicais parecem estar envolvidos na modificação dos polissacarídeos durante a torra. A identificação das modificações estruturais induzidas por tratamento térmico e oxidativo dos compostos modelo foi feita por estratégias analíticas baseadas principalmente em espectrometria de massa, mas também em cromatografia líquida. A cromatografia de gás foi usada na análise de açúcares neutros e ligações glicosídicas. Para validar as conclusões obtidas com os compostos modelo, foram também analisadas amostras de polissacarídeos do café obtidas a partir de resíduo de café e café instantâneo. Os resultados obtidos a partir dos oligossacarídeos modelo quando submetidos a tratamento térmico (seco), assim como à oxidação induzida por HO• (em solução), indicam a ocorrência de despolimerização, o que está de acordo com estudos anteriores que reportam a despolimerização das galactomananas e arabinogalactanas do café durante a torra. Foram ainda identificados outros compostos resultantes da quebra do anel de açúcares formados durante o tratamento térmico e oxidativo da Ara3. Por outro lado, o tratamento térmico a seco dos oligossacarídeos modelo (individualmente ou quando misturados) promoveu a formação de oligossacarídeos com um maior grau de polimerização, e também polissacarídeos com novos tipos de ligações glicosídicas, evidenciando a ocorrência de polimerização através reações de transglicosilação não enzimática induzidas por tratamento térmico a seco. As reações de transglicosilação induzidas por tratamento térmico a seco podem ocorrer entre resíduos de açúcares provenientes da mesma origem, mas também de origens diferentes com formação de estruturas híbridas, contendo arabinose e manose como observado nos casos dos compostos modelo usados. Os resultados obtidos a partir de amostras do resíduo de café e de café instantâneo sugerem a presença de polissacarídeos híbridos nestas amostras de café processado, corroborando a ocorrência de transglicosilação durante o processo de torra. Além disso, o estudo de misturas contendo diferentes proporções de cada oligossacarídeo modelo, mimetizando regiões do grão de café com composição distinta em polissacarídeos, sujeitos a diferentes períodos de tratamento térmico, permitiu inferir que diferentes estruturas híbridas e não híbridas podem ser formadas a partir das arabinogalactanas e galactomananas, dependendo da sua distribuição nas paredes celulares do grão e das condições de torra. Estes resultados podem explicar a heterogeneidade de estruturas de melanoidinas formadas durante a torra do café. Os resultados obtidos a partir de misturas modelo contendo um oligossacarídeo (Ara3 ou Man3) e 5-CQA sujeitas a tratamento térmico a seco, assim como de amostras provenientes do resíduo de café, mostraram a formação de compostos híbridos compostos por moléculas de CQA ligadas covalentemente a um número variável de resíduos de açúcar. Além disso, os resultados obtidos a partir da mistura contendo Man3 e 5-CQA mostraram que o CQA atua como catalisador das reações de transglicosilação. Por outro lado, nas misturas modelo contendo um péptido, mesmo contendo também 5-CQA e sujeitas ao mesmo tratamento, observou-se uma diminuição na extensão das reações transglicosilação. Este resultado pode explicar a baixa extensão das reações de transglicosilação não enzimáticas durante a torra nas regiões do grão de café mais ricas em proteínas, apesar dos polissacarídeos serem os componentes maioritários dos grãos de café. A diminuição das reações de transglicosilação na presença de péptidos/proteínas pode dever-se ao facto de os resíduos de açúcares redutores reagirem preferencialmente com os grupos amina de péptidos/proteínas por reação de Maillard, diminuindo o número de resíduos de açúcares redutores disponíveis para as reações de transglicosilação. Além dos compostos já descritos, uma diversidade de outros compostos foram formados a partir dos sistemas modelo, nomeadamente derivados de desidratação formados durante o tratamento térmico a seco. Em conclusão, a tipificação das modificações estruturais promovidas pela torra nos polissacarídeos do café abre o caminho para a compreensão dos mecanismos de formação das melanoidinas e da relação estrutura-atividade destes compostos.<br>Polysaccharides are the major components of green and roasted coffee beans, and coffee brew. The most abundant ones are galactomannans, followed by arabinogalactans. During the roasting process, galactomannans and arabinogalactans undergo structural modifications that are far to be completely elucidated due to their diversity and complexity of the compounds formed. During the roasting process, galactomannans and arabinogalactans react with proteins, chlorogenic acids, and sucrose, originating high molecular weight brown compounds containing nitrogen, known as melanoidins. Several biological activities and beneficial health effects have been attributed to coffee melanoidins. However, their exact structures and the mechanisms involved in their formation remain unknown, as well as the structure-biological activity relationship. The use of model systems and mass spectrometry analysis allow to obtain an overall view and, simultaneously, detailed, of the structural modifications in coffee polysaccharides promoted by roasting, contributing to the elucidation of the structures and formation mechanisms of melanoidins. Based on this thesis, oligosaccharides structurally related to the backbone of galactomannans, (β1→4)-D-mannotriose, and the side chains of arabinogalactans, (α1→5)-Larabinotriose, alone or in mixtures with 5-O-caffeoylquinic acid, the most abundant chlorogenic acid in green coffee beans, and dipeptides composed by tyrosine and leucine, used as models of proteins, were submitted to dry thermal treatments, mimicking the coffee roasting process. The oxidation induced by hydroxyl radicals (HO•) was also studied, since these radicals seem to be involved in the modification of the polysaccharides during roasting. The identification of the structural modifications induced by thermal and oxidative treatment of the model compounds was performed mostly by mass spectrometry-based analytical strategies, but also using liquid chromatography. Gas chromatography was used in the analysis of neutral sugars and glycosidic linkages. To validate the conclusions achieved with the model compounds, coffee polysaccharide samples obtained from spent coffee grounds and instant coffee were also analysed. The results obtained from the model oligosaccharides when submitted to thermal treatment (dry) or oxidation induced by HO• (in solution) indicate the occurrence of depolymerization, which is in line with previous studies reporting the depolymerization of coffee galactomannans and arabinogalactans during roasting. Compounds resulting from sugar ring cleavage were also formed during thermal treatment and oxidative treatment of Ara3. On the other hand, the dry thermal treatment of the model oligosaccharides (alone or when mixed) promoted the formation of oligosaccharides with a higher degree of polymerization, and also polysaccharides with new type of glycosidic linkages, evidencing the occurrence of polymerization via non-enzymatic transglycosylation reactions induced by dry thermal treatment. The transglycosylation reactions induced by dry thermal treatment can occur between sugar residues from the same origin, but also of different origins, with formation of hybrid structures, containing arabinose and mannose in the case of the model compounds used. The results obtained from spent coffee grounds and instant coffee samples suggest the presence of hybrid polysaccharides in these processed coffee samples, corroborating the occurrence of transglycosylation during the roasting process. Furthermore, the study of mixtures containing different proportions of each model oligosaccharide, mimicking coffee bean regions with distinct polysaccharide composition, subjected to different periods of thermal treatment, allowed to infer that different hybrid and non-hybrid structures may be formed from arabinogalactans and galactomannans, depending on their distribution in the bean cell walls and on roasting conditions. These results may explain the heterogeneity of melanoidins structures formed during coffee roasting. The results obtained from model mixtures containing an oligosaccharide (Ara3 or Man3) and 5-CQA and subjected to dry thermal treatment, as well as samples derived from spent coffee grounds, showed the formation of hybrid compounds composed by CQA molecules covalently linked to a variable number of sugar residues. Moreover, the results obtained from the mixture containing Man3 and 5-CQA showed that CQA acts as catalyst of transglycosylation reactions. On the other hand, in the model mixtures containing a peptide, even if containing 5-CQA and subjected to the same treatment, it was observed a decrease in the extent of transglycosylation reactions. This outcome can explain the low extent of non-enzymatic transglycosylation reactions during roasting in coffee bean regions enriched in proteins, although polysaccharides are the major components of the coffee beans. The decrease of transglycosylation reactions in the presence of peptides/proteins can be related with the preferential reactivity of reducing residues with the amino groups of peptides/proteins by Maillard reaction, decreasing the number of reducing residues available to be directly involved in the transglycosylation reactions. In addition to the compounds already described, a diversity of other compounds were formed from model systems, namely dehydrated derivatives formed during dry thermal treatment. In conclusion, the identification of the structural modifications in coffee polysaccharides promoted by roasting pave the way to the understanding of the mechanisms of formation of melanoidins and structure-activity relationship of these compounds.

Abstract:
碩士<br>國立成功大學<br>體育健康與休閒研究所<br>103<br>This study focused on walking with different additional weighted shoes. The purpose of this study was to analyze the lower extremity electromyography under wearing different weighted shoes and to find the gender influence on preference of the weighted shoes. Forty subjects (20 males & 20 females) who were used to exercise regularly included in this study. In the first experiment, the subjects were required to choose the most comfortable from five weighted shoes models with paired comparison. In the second experiment, an EMG device was used to simultaneously record lower extremity muscles activity when walking on the treadmill with sampling frequency of 1000/sec. The results of preference test showed that gender would affect preference model of weighted shoes. All male preferred weighted shoe D and E that the weight added on the rear tip of the sole. However, twelve females (60%) preferred shoe D and E, eight females (40%) preferred other shoe models. Gender had no significant influence on iEMG under different weighted shoes conditions. Participants who preferred different weighted shoes would have different muscle activation patterns. It was worthly noted that the minimum iEMG of lower extremity seemed to occur when the particpants wearing their preference weighted shoes. The habit of wearing shoes (COM position) and lower extremity skeletal alignment perhaps are the key factors leading to different weighted shoes preference between the male and female paticipants.

Abstract:
AbstractThe aerospace industry is aiming for a cleaner means of transport. One way to achieve this is by making transportation lighter, thus directly improving fuel efficiency and reducing environmental impact. A further aim, of the industry, is to reduce maintenance time to lessen operating costs, which can result in a reduction of air transport costs, benefitting both passenger and freight services. Current developments to support these aims include using advanced materials, with the current generation of aerospace structures being 50% composite materials. These materials offer a weight reduction whilst maintaining adequate stiffness; however, their damage mechanics are very complex and less deterministic than those of metals. This results in an overall reduced benefit. Structures are manufactured thicker using additional material to accommodate unknown or unpredictable failure modes, which cannot be easily detected during maintenance. A way to overcome these issues is the adoption of a structural health monitoring (SHM) inspection system.

Abstract:
&lt;em&gt;Abstract&lt;/em&gt;.—Managers seldom sample sufficient numbers of Muskellunge &lt;em&gt;Esox masquinongy &lt;/em&gt;to develop population specific weight–total length (TL) models and often rely on existing models to predict Muskellunge weight. However, substantial variation exists among these models and managers and anglers may be forced to report inaccurate Muskellunge weight estimates. We used TL, maximum girth, pectoral girth, sex, and adult female reproductive status data obtained from 869 anesthetized adult Muskellunge collected from three natural lakes in Iowa between 2012 and 2015 to identify the most important variables for estimating Muskellunge weight. We also compared the predictive performance of our model to five popular models for estimating Muskellunge weight using test data from Iowa Muskellunge and data from an outside population. Stepwise model selection identified a model including terms for TL, maximum girth, and pectoral girth as having the lowest Bayesian information criterion value; however, post hoc analyses of model accuracy found that a two-variable model including terms for TL and maximum girth was negligibly different from the three-variable model. Therefore, we selected the TL–maximum girth model as the best model and for use in additional analyses of model accuracy. Of the six models compared, our model and the Casselman and Crossman (1986) model performed well across the range of weights tested using the Iowa test data set; on average, estimated weights were within 2.7–5.5% of measured weights. All other models either grossly under- or overestimated Muskellunge weight. Model accuracy for all tested models decreased substantially when tested using data from the Georgian Bay Muskellunge population, especially for fish greater than 30 lb [13.6 kg]. Although our model and the Casselman and Crossman (1986) model will provide managers with weight estimates that are suitable for use in most fishery-management applications, they may not be suitable for anglers attempting to determine if angled Muskellunge are of record weight. In populations where extreme morphological differences may occur or robust weight–TL models need to be developed, we recommend that population specific models be developed to estimate Muskellunge weight.

Full text
Abstract:
Historically, educational accessibility in higher education appeared to be a dynamic and fluid scale with individual rights and accessibility on one side while institutional policies and procedures balanced the other side. Additional weights were applied to both sides of the scale. United States (U.S.) federal laws applied weight to the individual rights and accessibility side. Meanwhile, financial considerations applied weight to the institutional policies side. U.S. universities may have found this balancing act difficult through ongoing legal cases and law revisions. Critical Disability Theory (CDT) provides an alternative viewpoint to review education accessibility. CDT also encourages participation by more campus stakeholders to resolve accessibility issues and promote full accessibility on university campuses. This chapter will explore and explain the complex interconnections of laws, finances and policies in supporting accessibility on campuses and discuss potential guidelines for future institutional policies and procedures related to students with disabilities.

The focus of this investigation is to analyze the knee angle time series and calculate the divergence for different weight added in the exercise. Experiments are conducted and motion capture used for each of the cases. Then the Lyapunov exponents of the time series of the knee joint angle are determined. Matlab software package is used for all calculations. Results are compared with data available in the literature. This work provides insight on the level of stability for added weight on the human squat exercise. This gives an insight on the level of safety of this exercise as weight is added to the human subject.

Abstract:
Abstract The main focus of this work is to investigate the effect of weight on the stability of human squat exercise. The squat exercise is a common daily activity. Experiments are conducted using one human subject. A VICON motion analysis system integrated with Force Plates is utilized for these experiments. An experimental protocol is developed and followed. This work analyzes the time series of the normal component of the ground reaction forces and each coordinate of the center of pressure. These time series are used to estimate the Lyapunov Exponents using Rosenstein method. MATLAB software package is used for this investigation. The results of this work are compared with results from literature. Present work gives more information relating the safety of the squat exercise when adding additional weight. One can see that the effect of additional weight on stability depends on its value. In the cases of small and moderate additional weight the stability is the same or increases, while for the largest additional weight the investigated stability decreases.

Abstract:
Direct shape manipulation allows one to specify constraints on curves or surfaces to modify their shapes. This paper presents a new and simple method of direct manipulation of NURBS curves accomplished through the use of a weight function. Within a marked boundary, the curve can be forced to pass through given discrete points by using a synthesized weight function instead of repositioning control points. By introducing four additional derivative constraints to construct the weight function, exact locality and continuity can be easily obtained without knot insertion. B-spline interpolation is used to generate the weight function in the paper. The algorithms are easy to implement and can be used for interactive shape design systems.

Full text
Abstract:
Major design changes to the Propulsion Gas Turbine Air Inlet on the US Navy’s CG47 Class Guided Missile Cruisers have resulted in significant superstructure weight savings. The majority of weight reduction resulted from use of finite element analysis (FEA) computer modeling techniques applied to structural optimization. FEA models of the forward and aft deckhouses provided the necessary capability to analyze each structure’s response to loads simulating a nuclear air blast, shock, and vibration. Integration of the moisture separator housings into each deckhouse structure allowed improved structural stability and additional weight reductions. FEA modeling and a redesign of the major inlet system 32% lighter than inlets installed onearly ships of this class. The first of the lightweight deckhouses has been installed on the CG52 Cruiser.

Full text
Abstract:
The Federal Aviation Administration (FAA), Federal Transit Authority (FTA) and Coast Guard instituted or recently proposed an increase in the average passenger weight used to calculate load and conduct safety analysis and tests in multiple modes of transportation. The increased passenger weight requirements were created in response to the Center for Disease Control’s (CDC) documented rise in weight among the country’s citizens and followed crash or failure incidents in which a cause was overweight equipment. The current certification requirements under CFR 49, Part 567 state that Gross Vehicle Weight Rating (GVWR) of a motor vehicle shall not be less than the sum of the unloaded vehicle weight, rated cargo weight and 150 pounds times the number of designated seating positions. Actual occupant weight distributions versus certified weight per occupant seat causes a potential conflict between a vehicle’s in-use weight versus its certified GVWR. This paper is distinct in its contrasting of the 150 pound occupant standard in relation to documented actual occupant weight, clothing, personal items and baggage. A midsized bus example was used to explore the statistical probability that adult passengers and rated cargo would result in weight distributions that exceeded tire load capability, Gross Axle Weight Rating (GAWR), or GVWR. The unreliability of the 150 pounds per designated seat position in producing loaded weight under gross weight ratings was demonstrated for a midsized bus. Results demonstrated that load conditions and usage restrictions are identifiable and decrease the probability of operating in a condition that exceeds a weight rating. Weight assumptions that take into consideration well documented transportation industries baggage weight were identified as potentially confounding additional weight that may contribute to overload of midsized buses.

Abstract:
Shaking forces and moments are often undesired. Complete balancing of these effects usually is associated with considerable additional mass and inertia. This paper proposes a light-weight solution concept to the complete force and moment balancing of linkages based on the combination of a counterweight and a separate counter-rotation into a single element. This element will be called a counter-rotary counterweight (CRCW). It will be shown that for a 1dof rotatable link a reduction of added mass by about 40% and a reduction by about 20% of added inertia have been achieved, as compared to a standard solution, after optimization of both mechanisms for minimal inertia. Generalization of the proposed principle is also discussed.

Abstract:
Hybridization of a vehicle’s drivetrain can in principle help to improve its energy efficiency by allowing for recuperation of kinetic energy and modulating the engine’s load. How well this can be realized depends on appropriate sizing and control of the additional components. The system is typically designed sequentially, with the hardware setup preceding the development and tuning of advanced controller architectures. Taking an alternative approach, component sizing and controller tuning can be addressed simultaneously through simulation-based optimization. The results of such optimizations, especially with standard algorithms with continuous design variable ranges, can however be difficult to realize, considering for example limitations in available components. Furthermore, drive-cycle based optimizations are prone to cycle-beating. This paper examines the results of such simulation-based optimization for a series hydraulic hybrid vehicle in terms of sensitivity to variations in design parameters, system parameters and drive cycle variations. Additional relevant aspects concerning the definition of the optimization problem are pointed out.

Full text
Abstract:
Numerous extant studies are dedicated to enhancing the safety of active transportation modes, but very few studies are devoted to safety analysis surrounding transit stations, which serve as an important modal interface for pedestrians and bicyclists. This study bridges the gap by developing joint models based on the multivariate conditionally autoregressive (MCAR) priors with a distance-oriented neighboring weight matrix. For this purpose, transit-station-centered data in Los Angeles County were used for model development. Feature selection relying on both random forest and correlation analyses was employed, which leads to different covariate inputs to each of the two jointed models, resulting in increased model flexibility. Utilizing an Integrated Nested Laplace Approximation (INLA) algorithm and various evaluation criteria, the results demonstrate that models with a correlation effect between pedestrians and bicyclists perform much better than the models without such an effect. The joint models also aid in identifying significant covariates contributing to the safety of each of the two active transportation modes. The research results can furnish transportation professionals with additional insights to create safer access to transit and thus promote active transportation.

Abstract:
The BeefLedger Export Smart Contracts project is a collaborative research study between BeefLedger Ltd and QUT co-funded by the Food Agility CRC. This project exists to deliver economic value to those involved in the production, export and consumption of Australian beef to China through: (1) reduced information asymmetry; (2) streamlined compliance processes, and; (3) developing and accessing new data-driven value drivers, through the deployment of decentralised ledger technologies and associated governance systems. This report presents early insights from a survey deployed to Chinese consumers in Nov/Dec 2019 exploring attitudes and preferences about blockchain-credentialed beef exports to China. Our results show that most local and foreign consumers were willing to pay more than the reference price for a BeefLedger branded Australian cut and packed Sirloin steak at the same weight. Although considered superior over Chinese processed Australian beef products, the Chinese market were sceptical that the beef they buy was really from Australia, expressing low trust in Australian label and traceability information. Despite lower trust, most survey respondents were willing to pay more for traceability supported Australian beef, potentially because including this information provided an additional sense of safety. Therefore, traceability information should be provided to consumers, as it can add a competitive advantage over products without traceability.

Efficacy of florpyrauxifen-benzyl on dioecious hydrilla and hybrid water milfoil - concentration and exposure time requirements.

Full text
Abstract:
This study conducted small-scale trials under various concentration and exposure time (CET) scenarios to determine florpyrauxifen-benzyl activity on dioecious hydrilla and hybrid watermilfoil and determine impact on water stargrass and elodea. Hydrilla treated with 12, 24, or 36 μg active ingredient (a.i.) L⁻¹ florpyrauxifen-benzyl and exposed for 12, 24, or 48 hr under outdoor mesocosm conditions was reduced in biomass by 30-75% at 8 weeks after treatment (WAT). An additional hydrilla trial at the same herbicide concentrations, but under longer exposures (24, 72, or 168 hr), resulted in 33–85% plant control. Under indoor conditions, hybrid watermilfoil dry weight decreased 98–100% with subsurface applications of florpyrauxifen-benzyl under CET scenarios of 3–12 μg a.i. L⁻¹ at 3–24 hr exposure times in a growth chamber trial. Under shorter exposure periods (0.5–4 hr) in a follow-up trial, low doses (3–9 μg a.i. L⁻¹) achieved 50–100% control of hybrid watermilfoil. In the same trial, the nontarget species water stargrass and elodea proved relatively tolerant to the florpyrauxifen-benzyl at doses up to 6 μg a.i. L⁻¹ (4 hr exposure) and 9 μg a.i. L⁻¹ (1 hr exposure). These small-scale trials demonstrate florpyrauxifen-benzyl’s potential to selectively manage invasive species.

Full text
Abstract:
This report documents the findings from SPR-4230 (Alternative Quality Assurance Methods for Compacted Subgrade). The main objective of SPR-4230 involved establishing performance-related quality assurance (QA) test methods for pavement subgrade construction. Because INDOT generally prefers specifying subgrade treatment type IBC (i.e., 14-in. cement modified subgrade), this study focused on performance-based QA test methods for constructing cement modified subgrade. Moreover, INDOT prefers using light weight deflectometer (LWD) for chemically modified subgrade construction acceptance, so this study aimed to use LWD deflection measurements as performance-related construction acceptance criteria. A laboratory study was performed to relate LWD deflections with resilient modulus that is the key subgrade performance-related parameter in pavement design. In addition, LWD deflections were related with unconfined compressive strength increase that is the key parameter in chemical soil modification mix design. A rigorous field study consisting of LWD testing and falling weight deflectometer (FWD) testing at INDOT new pavement construction sites was conducted to verify the laboratory developed relationship. Recommendations for implementing results of this study into cement modified subgrade construction acceptance is provided, as are recommendations for future research.

Abstract:
Fly ash is a by-product of coal combustion, made up of particles that are collected through various methods. This by-product has been used successfully as a partial Portland cement replacement in concrete, but the performance predictions of fly ash in concrete have been difficult to predict, especially at high fly ash replacement rates. This study focuses on comparing the performance of concrete with a variety of fly ash mixtures as well as the particle distribution and chemical makeup of fly ash. The slump, unit weight, compressive strength, and isothermal calorimetry tests were used to measure the performance of concrete at 0%, 20%, and 40% fly ash replacement levels. The particle distribution of fly ash was measured with an automated scanning electron microscope. Additionally, the major and minor oxides from the chemical makeup of fly ash were measured for each mixture and inputted into a table. The particle distribution and chemical makeup of fly ash were compared to the performance of slump, unit weight, compressive strength, isothermal calorimetry, and surface electrical resistivity.

Full text
Abstract:
Aircraft Arresting Systems (AAS) for military applications utilize sacrificial panels made of Ultra-High Molecular Weight polyethylene (UHMWPE) that are embedded into the pavement beneath the AAS cable to protect the pavement from cable damage. Problems have been observed with the materials and practices used to seal the UHMWPE panel joints from water and debris. Data obtained from laboratory and field studies were used make improvements to current practice for sealing UHMWPE panel joints. The study evaluated four joint-sealant materials, eight alternative surface treatment and preparation techniques to promote adhesion to UHMWPE, and seven joint-edge geometries. Bond-strength testing of joint-sealant specimens was conducted in the laboratory, followed by field evaluation of construction techniques. Field performance of the joint systems was monitored for 24 months after installation. Additionally, a thermal response model was developed to refine the joint design dimensions. Results confirmed that the best material to use was self-leveling silicone joint sealant. It was recommended that a dovetail groove be cut into the edge of UHMW panels to provide positive mechanical interlock and to reduce adhesive failures of the sealant. It was also recommended that the panel-to-panel joint-sealant reservoir be widened to prevent sealant compression damage.

Full text
Abstract:
The term Reclaimed Asphalt Pavement (RAP) is used to designate a material obtained from the removal of pavement materials. RAP is used across the US in multiple applications, largely on asphalt pavement layers. RAP can be described as a uniform granular non-plastic material, with a very low percentage of fines. It is formed by aggregate coated with a thin layer of asphalt. It is often used mixed with other granular materials. The addition of RAP to aggregates decreases the maximum dry unit weight of the mixture and decreases the optimum water content. It also increases the Resilient Modulus of the blend but decreases permeability. RAP can be used safely, as it does not pose any environmental concerns. The most important disadvantage of RAP is that it displays significant creep. It seems that this is caused by the presence of the asphaltic layer coating the aggregate. Creep increases with pressure and with temperature and decreases with the degree of compaction. Creep can be mitigated by either blending RAP with aggregate or by stabilization with chemical compounds. Fly ash and cement have shown to decrease, albeit not eliminate, the amount of creep. Mechanical stabilizing agents such as geotextiles may also be used.

Full text
Abstract:
Industrial soil contamination is frequently unearthed by transportation agencies during construction within the right-of-way. As a result, transportation agencies may experience construction delays. Soils co-contaminated with high-molecular-weight polycyclic aromatic hydrocarbons (HMW-PAHs) and metals are commonly encountered in Illinois and exhibit recalcitrance towards conventional treatment technologies. This issue is exacerbated in the fine-grained soils common to Illinois, where low-permeability and immense sorption capacity increase treatment complexity, cost, and duration. Contaminated sites are spatially and temporally restrictive and require rapid in situ treatments, whereas conventional soil remediation requires 1 to 3 years on average. Consequently, transportation agencies typically pursue excavation and off-site disposal for expediency. However, this solution is expensive, so a comparatively expeditious and affordable treatment alternative is needed to combat the increasing cost of hazardous waste disposal. The objective of this work was to develop an accelerated in situ treatment approach adaptable for use at any construction site to cost-effectively remove HMW-PAHs and metals from clayey soil. It was hypothesized that an in situ electrochemical treatment which augments electrokinetics with H2O2 could remediate both HMW-PAHs and metals in less than a month. Bench-scale reactors resemblant of field-scale in situ electrokinetic systems were designed and fabricated to assess the electrochemical treatment of clayey soils contaminated with HMW-PAHs and metals. Pyrene, chromium, and manganese were used as model contaminants, spiked into kaolinite as a model clay. Electrokinetics were imposed by a low-intensity electrical field distributed by graphite rods. Electrolytic H2O2 systems were leveraged to distribute electrical current and facilitate contaminant removal. Average contaminant removals of 100%, 42.3%, and 4.5% were achieved for pyrene, manganese, and chromium, respectively. Successful development of this bench-scale treatment approach will serve to guide transportation agencies in field-scale implementation. The results from this work signify that electrochemical systems that leverage eco-friendly oxidant addition can replace excavation and disposal as a means of addressing clayey soils co-contaminated with HMW-PAHs and metals.
