Abstract:
<p>Oil palm fronds (OPF) is widely used as the source of roughage for the farm animals. However, the full potential of OPF as animal feed is limited by their high lignin content which limits the rumen microbe’s access to the cellulose and hemicellulose. White rot fungi (WRF) are a group of fungi belonging to basidiomycete phylum and are commonly found in decaying woody plant. They possess the ability to degrade lignin. This experiment aims to identify the phylum of the best lignin decaying fungi based on their enzymes activity. In this experiment, 11 fungi species were isolated from decaying oil palm fronds. They are labelled as WR1, WR 2, WR3, WR4, WR5, WR6, WR7, WR8, WR9, WR10 and WR11. Their fibernolytic enzyme activities which includes laccase, manganese peroxidase, lignin peroxidase, avicelase, carboxylmethylcellulase and xylanase are analysed using the solid state fermentation method. It <span style="text-decoration: line-through;">is</span> was found that 5 fungi species which are the WR1, WR2, WR4, WR7 and WR10 produced the highest ratio of lignin degrading enzyme to cellulose and hemicellulose degrading enzyme. The fungi are then analysed under microscope to determine the phylum of the fungi. From the observation, the fungi are identified to belong to the phylum basidiomycetes due to presence of clamp connection.</p>

Abstract:
Background: PCC (Kcentra®) is an Food and Drug Administration (FDA)–approved 4-factor PCC used for the treatment of warfarin-related coagulopathy (WRC), but it has also been used off-label to treat non-WRC. Three-factor PCC in the form of coagulation factor IX human (Bebulin®) has also been used for WRC and off-label to treat non-WRC. It is unclear whether the use of 3- or 4-factor PCCs is effective for the treatment of non-WRC,. Objective: Our aim is to characterize the use of 3- and 4-factor PCCs for patients identified with a non-WRC. Methods: A retrospective analysis of patients who received PCCs for both WRC and non-WRC between January 2012 and July 2015 was conducted. Results: A total of 187 patients with elevated international normalized ratio (INR) who received PCCs were analyzed; 53.9% of patients in the WRC group and 27.7% in the non-WRC group corrected to an INR of 1.3 or less after 3- or 4-factor PCC administration. In those patients with non-WRC and who had underlying liver disease, 3- and 4-factor PCCs reduced mean INR by 0.98 and 1.43, respectively. Conclusion: Three and 4-factor PCCs can reduce INR in patients with WRC and in those with non-WRC secondary to liver disease.

Abstract:
Actin remodeling is frequently regulated by antagonistic activities driving protrusion and contraction downstream of Rac and Rho small GTPases, respectively. WAVE regulatory complex (WRC), which primarily operates downstream of Rac, plays pivotal roles in neuronal morphogenesis. Recently, two independent studies described de novo mutations in the CYFIP2 subunit of WRC, which caused intellectual disability (ID) in humans. Although mutations had been proposed to effect WRC activation, no experimental evidence for this was provided. Here, we made use of CRISPR/Cas9-engineered B16-F1 cell lines that were reconstituted with ID-causing CYFIP variants in different experimental contexts. Almost all CYFIP2-derived mutations (7 out of 8) promoted WRC activation, but to variable extent and with at least two independent mechanisms. The majority of mutations occurs in a conserved WAVE-binding region, required for WRC transinhibition. One mutation is positioned closely adjacent to the Rac-binding A site and appears to ease Rac-mediated WRC activation. As opposed to these gain-of-function mutations, a truncating mutant represented a loss-of-function variant and failed to interact with WRC components. Collectively, our data show that explored CYFIP2 mutations frequently, but not always, coincide with WRC activation and suggest that normal brain development requires a delicate and precisely tuned balance of neuronal WRC activity.

Abstract:
Le mode de coordination parmi les différentes molécules qui régulent la migration reste très peu connu. Ce travail traite de deux voies de transduction régulant la migration: la voie Rac1/WRC (Wave Regulatory Complex) qui contrôle la formation du réseau d’actine au front des cellules migrantes, et la voie RalB/exocyst, dont les mécanismes moléculaires de son implication dans la motilité cellulaire étaient inconnus au début de cette thèse. Rac1 et RalB sont des petites protéines G des familles Rho et Ras, respectivement. Les complexes WRC et exocyst sont leurs effecteurs directs.Au cours de la recherche de connexions entre l’exocyst et des régulateurs de la migration, nous avons trouvé que deux sous-unités de l’exocyst, Exo70 et Sec6, interagissent directement in vitro avec Abi et Cyfip, respectivement, deux sous unités du WRC. De plus, nous avons trouvé que les sous-unités de l’exocyst peuvent interagir in vitro avec le WRC entier. Nous avons également montré que ces deux complexes s’associent in vivo. Sur le plan fonctionnel, l’exocyst est requis pour le positionnement du complexe WRC au front des cellules migrantes. D’autre part, nous avons également trouvé que deux autres sous- unités de l’exocyst Sec8 et Exo84, interagissent avec SH3BP1 (une RhoGAP) en double hybride et en co-immunoprécipitation. SH3BP1 se localise au front des cellules migrantes, et cette localisation dépend de l’exocyst. De façon intéressante, in vivo, la voie RalB/exocyst/SH3BP1 cible spécifiquement Rac1, et non Cdc42. Grâce à plusieurs approches, nous concluons que SH3BP1 est requis pour inactiver Rac1 au front. Dans notre modèle nous proposons que RalB/exocyst règulerait la migration cellulaire en véhiculant au front de migration deux éléments majeurs de la signalisation de Rac1 : son complexe effecteur WRC, qui stimule la nucléation de filaments d’actine et son régulateur négatif SH3BP1, une GAP qui promeut l’inactivation et le cycle GDP/GTP de Rac1. En conclusion, ce travail fournit de nouvelles connexions moléculaires et fonctionnelles entre l’exocytose polarisée et la dynamique de l’actine au cours de la motilité cellulaire<br>Very little is known about the coordination and the integration among the different regulators of the motility process. This work deals with two migration-regulatory pathways: the Rac1/WRC (Wave Regulatory Complex) pathway that drives the formation of the actin polymerization network at the front of motile cells; and RalB/exocyst pathway for which the molecular mechanisms underlying its implication in cell motility were still largely unknown at the beginning of this thesis. Rac1 and RalB are small GTPases of the Rho and Ras family, respectively. WRC and exocyst complexes are their direct effectors.In searching for connections between the exocyst and migration regulators, we found that two subunits of the exocyst, Exo70 and Sec6, interact directly in vitro with two subunits of the WRC, Abi and Cyfip, respectively. Moreover, we found that exocyst subunits can interact in vitro with the whole fully-assembled WRC complex. We also showed that these two complexes associate in vivo. Functionally, the exocyst was required for WRC complex positioning at the front of migrating cells.On the other hand, we also found that two other subunits of the exocyst, Sec8 and Exo84, interact with SH3BP1 (a RhoGAP protein) by two-hybrid assay and by co-immunoprecipitation. SH3BP1 localizes at the leading edge and this localization is dependent on the exocyst. Interestingly, in vivo, the RalB/exocyst/SH3BP1 pathway specifically targets Rac1, and not Cdc42. By a combination of approaches we concluded that SH3BP1 is required to inactivate Rac1 at the front.In our model we propose that RalB/exocyst regulates cell migration by driving to the leading edge two key signaling elements of the Rac1 pathway: its effector WRC, that stimulates actin filament nucleation, and its negative regulator SH3BP1, a GAP promoting Rac1 inactivation and GDP/GTP cycling. In conclusion, this work provides novel molecular and functional links between polarized exocytosis and actin dynamics during cell motility

Abstract:
La formation des métastases est un processus multi étapes à travers lequel les cellules cancéreuses se détachent de la tumeur primaire pour envahir à distance dans un site secondaire. L’acquisition de capacités migratoires et invasives des cellules tumorales est cruciale dans la cascade métastatique. L'activation mutationnelle des protéines Ras favorise l'oncogenèse en perturbant une multitude de molécules et de voies qui sont impliquées dans la régulation de plusieurs processus, y compris l'invasion cellulaire et la motilité. Les petites Rho GTPases (Rac1, Cdc42 et RhoA)jouent un rôle central en contrôlant la migration cellulaire via l'assemblage des fibres d'actine, la contractilité de l'actomyosine et des microtubules.Rac1 stimule la motilité de type mésenchymateuse en favorisant la formation de lamellipodes via la formation du complexe régulateur Wave(WRC), un promoteur clé de la polymérisation de l'actine. Les protéines Ral,une autre famille de petites GTPases agissant en aval de Ras, a récemment été impliquée dans la régulation de la migration cellulaire. En particulier,RalB joue un rôle essentiel dans la motilité cellulaire en mobilisant le complexe Exocyst, son principal effecteur. Durant mon projet de thèse,nous avons investigué les mécanismes moléculaires qui contrôlent la motilité cellulaire et l'invasion en aval de la voie oncogénique Ras via le complexe RalB / Exocyst.Dans la première partie de ce manuscrit, nous avons identifié et caractérisé que le complexe WRC est à la fois un nouveau partenaire et mais aussi acteur du complexe Exocyst. En outre, nous démontrons que le complexe Exocyst dirige le complexe WRC à l’extrémité des cellules4mobiles. Cette hypothèse a été caractérisée dans la deuxième partie du manuscrit. En effet, en utilisant la technique d’optogénétique nous avonsmis en évidence le mécanisme moléculaire impliqué dans l'invasion.L’activation de RalB par Ras via les facteurs d'échange Rgl1 et Rgl2,mobilise le complexe Exocyst qui recrute ainsi le complexe WRC à l’extrémité des cellules. Cette cascade d’activation favorise la formation de protrusions, la migration et l'invasion. De manière surprenante, nous montrons que la GTPase Rac1, considérée comme la GTPase clée dans la formation de protrusions cellulaires, n'est pas impliquée dans ce processus.Enfin, nous avons analysé le niveau des protéines Ral dans une cohorte de patientes atteintes de cancer du sein. Nos résultats montrent pour la première fois une accumulation de la protéine RalB dans les compartemets invasif et métastatique suggérant un rôle potentiel de RalB dans l'invasion et la propagation métastatique des cancers du sein humain. Pour conclure,notre travail met en évidence un rôle crucial de la voie Ral, souvent sousestimée,dans le contexte de l'invasion cancéreuse<br>Metastasis is a multistep process by which cancer cells migrate awayfrom the primary neoplastic mass to give rise to secondary tumors at distantsites. Thus, the acquisition of motility and invasive traits by tumor cells is acrucial step for metastasis to occur. Mutational activation of Ras proteinspromotes oncogenesis by disturbing a multitude of molecules andpathways that participate to the regulation of several processes includingalso cell invasion and motility. Among them a central role is played by Rhosmall GTPases (Rac1, Cdc42 and RhoA) which control cell migrationthrough their actions on actin assembly, actomyosin contractility andmicrotubules. Rac1 drives mesenchymal-type motility by promotinglamellipodia formation via the Wave Regulator Complex (WRC), a keypromoter of actin polymerization. Another family of small GTPases that actdownstream Ras, the Ral proteins, has been recently involved in theregulation of cell migration. RalB, through the mobilization of its maineffector the Exocyst complex, was shown to play an essential role in cellmotility. In this work of thesis, we investigated the molecular mechanismsthrough which RalB/Exocyst pathway controls cell motility and invasiondownstream oncogenic Ras.In the first part of this manuscript we describe the identification andcharacterization of the WRC complex as a novel interactor of the Exocyst.Furthermore, we provide evidences for Exocyst to be involved in drivingthe WRC to the leading edge of motile cells. This hypothesis, was finallydemonstrated in the second part of the manuscript. We were able to definethe mechanisms underlying the function of RalB in invasion by exploitingan optogenetic approach. We found that RalB, activated by Ras via the2Rgl1 and Rgl2 exchange factors, mobilizes the Exocyst complex whichrecruits the Wave Regulatory Complex (WRC) at cell edge, promotingprotrusions, migration and invasion. Even more, we show that the Rac1GTPase, usually considered the master of cell protrusions, is not involvedin this process. Finally, we analyzed Ral proteins expression in a cohort ofbreast cancer samples, pointing out for the first time an accumulation ofRalB in the invasive and metastasis compartments, suggesting a role ofRalB in invasiveness and metastatic spread of human breast cancers. Takentogether our work contribute to light up the role of the underestimated Ralpathway in the context of cancer invasion

Abstract:
Memoria para optar al título de Ingeniero Civil Mecánico<br>En Chile y en gran parte del mundo se utiliza el código ASME VIII, para el diseño, fabricación y montaje de recipientes a presión. Sin embargo, las reglas de montaje del piping, no suelen ser respetadas, provocando fallas en los equipos. Esto es de suma importancia en ingeniería ya que las empresas fabricantes son las responsables de entregar la memoria de cálculo correspondiente. En base a esto, el objetivo general de esta memoria consiste en calcular la capacidad de carga en las boquillas de recipientes a presión, debido a fuerzas externas. Para esto, se deben desarrollar dos procedimientos de análisis: El WRC 107 y una técnica FEM. Los cuales son aplicados en un caso base y en un conjunto de aplicaciones. De esta manera, poder realizar una comparación entre los resultados de ambos análisis. Para lograr los objetivos, se evalúan 3 tipos de cargas: Una carga radial (P), un momento circunferencial (Mc) y uno longtudinal (Ml). Se aplica la metodología del WRC 107 imponiendo la condicion del límite de fluencia del material. Mientras que el FEM (Ansys), consiste en encontrar el instante en donde comienza la deformación plástica, debido a la carga aplicada. De esta manera se puede determinar de forma directa la magnitud. El resultado del caso base, muestra una mayor capacidad de carga en la boquilla de 10 in con respecto a la de 6 in, en ambos análisis (WRC 107 y FEM). Sin embargo, la diferencia entre cada uno de ellos es aproximadamente de un 60 %. Esto se debe a que WRC 107 no considera todos los refuerzos cercanos a la boquilla que presenta el caso base real. Los resultados correspondientes al conjunto de estanques seleccionados, muestran una tendencia a disminuir la capacidad de carga de las boquillas, en función del aumento del parámetro D=T del recipiente. Tanto para el análisis del WRC 107 como para el FEM. Esto muestra que el manto se comporta cada vez más similar a una membrana, perdiendo rigidez. También, se aprecia una diferencia entre ambos métodos de al menos un 29 %. Sin embargo, para la carga ML en la boquilla de 10 in, se presenta una diferencia de solo un 8 %. Se concluye que realizar el análisis de capacidad de carga en un caso real, conlleva a muchas consideraciones que no estan incluidas en el WRC 107, afectando considerablemente los resultados (WRC 107 hasta un 60% más conservativo que FEM). Para los casos parametrizados en funcion de D=T del estanque, se reafirma que WRC 107 es conservativo. Sin embargo, solo para la carga radial y momento circunferencial. No así para el momento longitudinal. Finalmente se destaca la importancia de realizar una técnica FEM para obtener resultados confiables.

Abstract:
The use of wood-plastic composites, WPC, in commercial products is today limited. Current WPC products on the market are to a large extent limited to extruded products. There are strong reasons to increase the use of WPC. WPC can be manufactured from used plastic that otherwise cannot be recycled. This paper gives a brief description of the manufacturing of WPC, including wood filler treatment, the role of coupling agents and compounding. It describes the machinery used for producing WPC, and gives a introduction to mold manufacturing.The use of WPC as an alternative to pure thermoplastics in injection molding processes is discussed. Furthermore it is described how WPCs differ from pure thermoplastics in terms of chemical and physical properties. The paper also describes the consequences of these properties in an injection molding cycle. The work finally puts focus on how to obtain process optimization through better understanding of pressure and temperature throughout the injection molding cycle.

Abstract:
Vital statistics data were statistically analyzed to determine who is breastfeeding in central Kentucky and if factors differ between those in a WIC and non-WIC population. The sample consisted of 479 postpartum women aged 18-44 in central Kentucky. Participants in the study were analyzed as a whole, then divided by their participation in the WIC program (n=304) or non-participation in the WIC program (n=175). Variables recorded in the vital statistics form were analyzed. These variables included age, education level, marital status, and ethnicity of the mother, household income status, and gender, gestational age, and birth weight of the infant. In the population studied, education level, ethnicity, marital status, household income status, and gestational age of the infant were significantly different between mothers who initiated breastfeeding and those who did not. In the WIC population, mothers were more likely to initiate breastfeeding if they were of non-white ethnicity or if the infant was born at greater than 37 weeks gestation; whereas, in the non-WIC population, mothers were more likely to initiate breastfeeding if they had some college or a college degree or if they were not enrolled in Medicaid. WIC participants were significantly less likely to initiate breastfeeding than non-WIC participants.

Abstract:
The Special Supplemental Women, Infants, and Children (WIC) Program is one of many United States Department of Agriculture's (USDA) food subsidy programs that serves 8.6 million participants, deemed nutritionally at risk. WIC is designed to influence nutritional and health behaviors to a population least capable of functioning. The purpose of this study was to identify if participation in WIC's nutrition education activities and restricted use of food subsidy benefits had a post-factorial effect on their nutritional behaviors. This study provides data on Bronfenbrenner's social ecological influences and how it impacts on long-term behavioral change. A quantitative causal-comparative design utilizing a convenience sampling method compared responses to a survey on nutritional habits of women shoppers at a Walmart retailer in an urban southeastern metropolitan city. The study population included women aged 18-50 years with one or more child who had or were currently receiving WIC (n = 63) compared with controls (n = 32) who also met the aforementioned criteria, yet did not receive WIC. Analyses of a Wilcoxon signed rank test supported an association between participation in WIC and an influence on participants' food purchase habits, while evidence from a linear equation for repeated measures between groups did not support a common variable for what influenced purchases between cases and controls. This study provides insight for future study regarding WIC's effectiveness to promote long-term health for its participants. It may also lend to discussion by USDA officials to consider programmatic review and change of other food subsidy programs which conceivably could impact the diets of more than 49 million Americans.

A sectional beam in hybrid design (Aluminum &amp; WPC [70 % PP / 30 % softwood]) was implemented in this aluminum beam overhead conveyor. During the conveying process the vertical acceleration of the transported material (dummy loads) was measured. At the beginning of the endurance test the acceleration patterns of the aluminum and the hybrid beams did not differ. Despite of mechanical wear of the drive system after 1000 operating hours, alterations of the acceleration patterns still could not be detected in the different beams. The hybrid beam remained fully functional with no visible wear or damage after 1000 operating hours. Based on these encouraging results the endurance test is continued with enhanced dummy loads and the development of a beam completely composed of WPC is aspired

A series of t-tests, performed between the means of the weekly weight gains, showed no significant difference in the weekly weight gain of the two samples at any week of pregnancy.</p> <p> Both samples had increased weekly weight gains near the end of pregnancy - the mean of the non-WIC group was higher and occurred slightly later than did that of the WIC group. These higher means near the end of pregnancy for the non-WIC group resulted in statistically significant differences in the two groups when comparing the last part of pregnancy and suggest that the non-WIC group is gaining a larger amount of weight very late in pregnancy.</p><br>Master of Science

Full text
Abstract:
Various methods have been in use for the determination of stresses at the nozzle-shell junction due to external loads and moments. Some methods evaluate stress in the cylindrical or spherical shell (e.g. WRC 107 now WRC 537) while others evaluate stresses in cylindrical shells and nozzles (e.g. WRC 297). ASME Section VIII Division. 2 specifies use of WRC 107/WRC 297 or Finite Element Analysis (FEA) for determination of stresses at shell-nozzle junctions with external loads and moments on the nozzle. Each method could yield a different result for the same loading condition and geometry and this has been recognized in comparisons made in WRC 297 with WRC 107 and FEA. Further, customized FEA software are also available for this analysis. There still seems to be some confusion in users of these methods regarding selection of method for optimization of design. Users not familiar with Finite Element Method prefer to use calculations based on WRC 107/297. Hang-Sung Lee, et.al. have recently (PVP 2011 – 57407) analyzed nozzle shell junctions using the Finite Element Method, compared their results with calculations to WRC 297 and made recommendations. The work presented in this paper is not an attempt to compare individual stresses obtained by classical versus analytical methods. Instead, an attempt has been made to consolidate the results obtained by the various methods into charts to enable a user to make a preliminary assessment to ascertain under what geometrical conditions the calculations made by each of the above methods would result in overall Code acceptable stresses without the results being either overly conservative or un-conservative. This is particularly relevant to the geometries which use the graphs and charts which have been extrapolated without rigorous theoretical background in the WRC Bulletin 537. The Finite Element Method has been used as the referee method.

Abstract:
Airborne particles of mineral dust play a key role in Earth’s climate system and affect human activities around the globe. The numerical weather modeling community has undertaken considerable efforts to accurately forecast these dust emissions. Here, for the first time in the literature, we thoroughly describe and document the Air Force Weather Agency (AFWA) dust emission scheme for the Georgia Institute of Technology–Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) aerosol model within the Weather Research and Forecasting model with chemistry (WRF-Chem) and compare it to the other dust emission schemes available in WRF-Chem. The AFWA dust emission scheme addresses some shortcomings experienced by the earlier GOCART-WRF scheme. Improved model physics are designed to better handle emission of fine dust particles by representing saltation bombardment. WRF-Chem model performance with the AFWA scheme is evaluated against observations of dust emission in southwest Asia and compared to emissions predicted by the other schemes built into the WRF-Chem GOCART model. Results highlight the relative strengths of the available schemes, indicate the reasons for disagreement, and demonstrate the need for improved soil source data.
