This thesis deals with a project of a lever-jack used for a race car. Its aim is to design a suitable model responding to all needs of such mechanism. The work itself is divided into several chapters. The first chapter is mainly theoretical, focusing on introduction of different types of lever-jacks. Further on, two engineering designs were created (mechanical and hydraulic). Kinematic calculation and strength calculation of some selected parts were done for each of these designs.

Gousiekte (“quick” disease) is a plant-induced cardiomyopathy of livestock in South Africa, that is characterized by the sudden death of animals within a period of 3-6 weeks after the initial ingestion of toxic plant material. Six species of three genera of the Rubiaceae family viz. Pachystigma pygmaeum, P. thamnus, and P. latifolium; Pavetta harborii and P. schuman-niana, and Fadogia homblei have been identified as the causative agents of the disease. The toxin responsible for the poisoning, named pavettamine, has been isolated and the structure and absolute configuration established as (2S,4R,8R,10S)-1,11-diamino-6-aza-undecane-2,4,8,10-tetraol, or the enantiomer, by mass spectrometry and NMR spectroscopy. Retrosynthetic analysis of the pavettamine molecule as outlined in the dissertation showed that the secondary amine function could be obtained from the amide functional group in an intermediate such as (2R,4S)-N-[(2′R,4′S)-2,4,5-trihydroxypentan-1′-yl]-2,4,5-trihydroxy-pentanamide A. Disconnection of the amide bond then generated two C5 building blocks viz. an amine B and a carboxylic acid C which through a set of functional group transformations led to a common C5 building block, a pentane-1,2,4,5-tetraol D. The terminal primary hydroxy groups required different protecting groups at all times in order to safe-guard the integrity of the two stereogenic centres. In addition identical protecting groups but different to those used for the primary hydroxy groups, were necessary for the secondary hydroxy groups. Further analysis of the C5 building block D showed that it could be obtained from (2S)-malic acid by functional group transformations, chiral sulfoxide methodology and an appropriate protective group strategy. A suitable protective group strategy was developed and an 11 step synthetic route for the C5 building block established. The successful conversion of this moiety through functional group transformations provided the C5 amine B and C5 carboxylic acid C which were linked to give the target compound, the amide D but with the hydroxy groups protected. The synthetic study presented in the dissertation provides an efficient methodology toward the synthesis of any of the 10 possible stereoisomers of pavettamine. / Dissertation (MSc)--University of Pretoria, 2009. / Chemistry / unrestricted

Syfte: Syftet med det här examenarbete är att undersöka behovet av snabbkopplingsadaptrar för protesbrukare.   Bakgrund: Snabbkopplingsadapter är en förhållandevis ny produkt som både Otto Bock och Lindhe Xtend erbjuder, men ingen forskning på behovsområdet finns ännu gjord. Fördelen med produkten är enligt leverantörernas hemsidor bl a att man med den enkelt kan byta mellan olika proteskomponenter utan att behöva skruva på några protesinställningar eller byta hylsa.   Metod: För att undersöka behovet av snabbkopplingsadaptrar utfördes semistrukturella intervjuer av fenomenologisk karaktär. En serie med sju frågor sammanställdes som intervjuunderlag, vilka togs fram utifrån de tre behovsfokusområdena: Funktion, delaktighet och livskvalité. I undersökningen ingick n=6 deltagare, varav n=3 transtibialt amputerade och n=3 transfemoralt amputerade. Insamlade data analyserades vidare för framtagning av olika teman och resultat.   Resultat: Utifrån intervjuunderlaget togs följande teman fram: Byte av protesfötter/protesknäleder, På- och avtagning av byxor, Hylspassform, Transport samt Biomekanik. Varje tema utgjorde ett eget potentiellt användningsområde, där de största behoven visade sig ligga inom temana Byte av protesfötter/protesknäleder, Hylspassform samt Transport.   Slutsats: Behovet av snabbkopplingsadaptrar är högst subjektivt, och beror snarare på deltagarens liv än några allmänna faktorer. Däremot upptäcktes ett antal tänkbara användningsområden för den. / Aim: The aim of this thesis was to investigate the necessity of the quick change adapter for lower limb amputees.   Background: Quick Change Adapter is a relatively new product that both Otto Bock and Lindhe Xtend offers, but no research has been done on the area of its necessity yet.  According to the supplier´s websites the benefits of the product is that you with it easily can change prosthetic components without affecting the alignments or change socket.   Method: To investigate the necessity of the Quick Change Adapter, semi structural interviews of phenomenological characteristic were used.  A series of seven questions were compiled as a basis for the interview from the three focus areas: Function, participation and quality of Life. The thesis involved n=6 participants, of who n=3 was trantibial amputated and n=3 transfemoral amputated. Collected data was later analysed to find general themes and results.   Results: From the interviews these themes were exposed: Changing prosthetic feet/prosthetic knee joints, Donn and doff of pants, Socket fit, Transport and Biomechanics. Each theme presented a potential application area where the biggest needs seemed to be in Changing prosthetic feet/prosthetic knee joints, Socket fit and Transport.   Conclusions: The necessity of the Quick Change Adapter turned out to be very subjective, and depended more on the participant´s life then any general factors. Still there were some potential application areas detected for it.

The process of grading code submissions in programming courses is time-consuming and error-prone. To address this issue, we propose a project that automates the testing and grading process for Java code submissions at Halmstad University. Our approach leverages property-based testing using the JUnit Quick-Check library to generate tests and test reports automatically.   The tool we demonstrate in this project is designed to provide students with immediate feedback on their code submissions and reduce the workload for instructors. By automatically generating tests and test reports, our approach ensures that code submissions meet the required specifications and are free from common errors. The com.pholser library is utilized to implement the property-based testing approach.   We believe that our project has the potential to improve the grading process for programming courses and provide a more efficient and effective way of assessing student code submissions. Our implementation can be easily extended to support other programming languages and can be integrated with existing learning management systems to provide a seamless experience for instructors and students alike. / Processen för att bedöma kodinlämningar i programmeringskurser är vara tidskrävande. För att lösa problemet, vill vi automatisera testerna och generera en testrapport för Javainlämningar vid Högskolan i Halmstad. Vi tillhandahåller ett verktyg som med hjälp av Property-Based Testing och JUnit Quick-check biblioteket underlättar denna process för lärarna. Verktyget är utformat för att kunna ge studenterna direkt återkoppling på deras inlämningar. Genom att automatiskt generera tester och testrapporter säkerställer vi att inlämningarna uppfyller de krav som läraren specificerar.   Detta projekt har potential att förbättra rättningsprocesser i programmerings- kurser genom att testa inlämningar på ett systematiskt och likvärdigt sätt och genom att vara ett mer effektivt sätt att bedöma studenternas inlämningar. Verktyget skulle kunna integreras med en Learning Management System för att även automatisera nerladdning av inlämningar och uppladdning av resultat.

L'hydrotraitement est un procédé catalytique important dans le raffinage du pétrole qui utilise des catalyseurs bimétalliques sulfurés NiWS ou NiMoS (ou CoMoS) supportés sur alumine. Leur mode conventionnel de préparation implique l’imprégnation d'une solution aqueuse de sels de Mo/W et de Ni/Co, puis l’activation par un agent sulfo-réducteur (H2S/H2). Pour répondre aux exigences environnementales et améliorer l'efficacité de l'hydrotraitement, des améliorations permanentes de la performance de ces systèmes catalytiques sont attendues. Ce travail se concentre sur la préparation de catalyseurs d'hydrotraitement hautement actifs par une approche de chimie de surface contrôlée (CSC) qui implique l'imprégnation successive de précurseurs moléculaires de MoV et NiII en solvant organique sur un support silice-alumine traité thermiquement. Dans la première partie de cette thèse, la genèse de la phase active du catalyseur CSC et conventionnel Mo et NiMo est étudiée par quick-XAS combinée à d’autres techniques (chimiométrie, XPS, RPE, STEM-HAADF, modélisation moléculaire). Nous proposons ainsi des structures moléculaires depuis les précurseurs oxydes de Mo et Ni supportés jusqu’aux nombreuses espèces intermédiaires (oxysulfure et sulfures) en fonction de la température. Cette analyse multi-technique permet d'abord de révéler les spécificités de la genèse des catalyseurs CSC et conventionnels qui peuvent expliquer leurs différentes activités catalytiques. Ensuite, elle révèle également de nouvelles connaissances sur les mécanismes d’insertion du Ni dans la phase NiMoS en fonction de la préparation. Dans la seconde partie, la possibilité de remplacer Co et Ni comme promoteurs est explorée. Ceci est entrepris en synthétisant des catalyseurs alternatifs de type XYMoS, où X et Y sont des métaux de transition 3d. Comme suggéré par des études de modélisation quantiques antérieures, certaines formulations XYMoS peuvent présenter un effet de synergie analogue à ceux des phases actives CoMoS et NiMoS. L’étude des formulations les plus prometteuses méritent d'être approfondies afin de mieux comprendre leur fonctionnement. / Hydrotreating is an important catalytic process in petroleum refining which uses sulfided bimetallic catalysts NiWS or NiMoS (or CoMoS) supported on alumina. Their conventional preparation involves an incipient wetness impregnation of an aqueous solution of Mo/W and Ni/Co salts, and then activation by a sulfo-reductive agent (such as H2S/H2). To meet environmental regulations and improve the energy efficiency of hydrotreatment, permanent improvements on the performance of these catalytic systems are expected. This work is thus focused on the preparation of highly active hydrotreating catalysts through a controlled surface chemistry (CSC) approach; which involves the successive impregnation of Mo5+ and Ni2+ molecular precursors in an organic solvent on a thermally treated silica-alumina support. In the first part of this thesis, the active phase genesis of CSC and conventional Mo and NiMo catalysts is studied by in situ quick-XAS combined with various other techniques (chemometrics, XPS, EPR, STEM-HAADF, molecular modeling). We thus propose molecular structures from the oxide of supported Mo and Ni precursors up to the numerous intermediate sulfided species as a function of temperature. This multi-technique analysis enables first to reveal the specific features of the genesis of CSC and conventional catalysts which may explain their different catalytic activities. Then, it also reveals new insights into the mechanisms of Ni promoter incorporation into the NiMoS phase as a function of the preparation. In the second part, the feasibility of replacing Co and Ni as promoters is explored. Using the CSC method, we attempted to synthesize alternative catalysts of the form XYMoS ternary sulfides, where X and Y are 3d transition metals. As suggested by previous quantum simulations, certain XY formulations possibly reveal a synergy effect as observed in CoMoS and NiMoS active phases. The most promising formulations merit further investigations.
