Abstract:
Especially in the context of a university, the architecture of a chemistry building can aim for expression of objectivity and functionalism. Space dedicated to research is a part of a basic desire for new insights and can contribute through its form to an understanding of the role of research. Conversations with chemistry students suggest that both space layout and quantity of laboratories can be improved. Perhaps the architecture can provide an additional stimulus beyond the basic needs of students and researchers. The proposed chemistry building focuses primarily on architectural sensory and experiential qualities inspired by architects Louis Kahn and Peter Zumthor. The project proposes more laboratories with a better academic research environment combined with more public space for enjoyment beyond the research life. Located at an important strategic site on campus, the building serves both as campus infrastructure and chemistry laboratories. The facade is intended as an assembly of grey precast concrete elements. The complex is divided into two main functional wings connected by a sculptural steel-glass stair object. The two wings serve as laboratories and offices, while the central glass stair offers a strong identity with a memorable space. The form offers a conversation between tradition and the future. The research part utilizes regular concrete structure with glass between the divisional walls, while the sculptural stair with its striking external form provokes a dialogue between art and science

Abstract:

In response to the growing need for early disease detection and diagnosis, Mastergene aims to provide genetic testing services ranging from new born screening to diagnostic screening for individuals up to 65 years of age to gain insight into their genetic information & understand their own health & personal information. This information will assist individuals in making treatment decisions for healthy living. Through Indian healthcare market analysis, it is evident that there exists a huge gap between hospitals and patients when it comes to understanding genetic testing and its benefits. Mastergene, with its innovative in-house laboratory, will arise awareness amongst the general population and will facilitate early detection of highly prevalent diseases in the Indian community. As a stand-alone diagnostic laboratory, Mastergene will outsource genetic testing kits from a supplier, send it to its patients on order and obtain patient’s sample in that genetic test kit for testing purposes. In conclusion, Mastergene will bring this enormous breakthrough to diagnose the disease from its root cause rather than symptoms alone.

Resumo: Este trabalho teve como objetivo obter, estudar e avaliar algumas propriedades geotécnicas do subsolo da região norte de Campinas, de grande importância para a pratica e desenvolvimento da engenharia geotécnica da região e do Estado de São Paulo. Foram coletadas amostras indeformadas e deformadas através da abertura de um poço de inspeção no Campo Experimental para estudos de Mecânica dos Solos e Fundações da UNICAMP (Campus Campinas), localizado na FEC - Faculdade de Engenharia Civil, Arquitetura e Urbanismo. Procurou-se atingir tais objetivos através da realização de ensaios laboratoriais (caracterização, resistência, deformabilidade, permeabilidade e sucção) e de correlações entre os parâmetros obtidos através dos ensaios, visando classificar o subsolo, dando enfoque a sua condição laterítica e não saturada. Ensaios edométricos simples foram realizados com o solo na condição natural e com inundação nas tensões de 100kPa, 200kPa e 400kPa para analise da colapsibilidade. Dos resultados obtidos, verificou-se que o solo se apresenta colapsível para todas as tensões de inundação. A partir dos resultados experimentais, fez-se a correlação de alguns parâmetros utilizando-se o programa de computador Wolfram Mathematica 7.0, verificando-se qual função melhor se ajustava para a correlação desejada
Abstract: This research aimed to study and evaluate some geotechnical properties of the northern region of Campinas soil profile, which have great importance for practice and development of geotechnical engineering in the Sao Paulo State. Disturbed and undisturbed samples from the subsoil were collected through the opening of inspection shafts at the experimental site for studies of Soil Mechanics and Foundations, UNICAMP (Campus Campinas), located on the FEC - Faculty of Civil Engineering, Architecture and Urbanism. In order to achieve these goals, laboratory tests have been performed, such as: characterization, resistance, compressibility, permeability and suction as well as correlation between parameters obtained from the tests to classify subsoil, giving emphasis to its unsaturated and lateritic condition. Oedometer tests were performed with the soil in natural and flooded condition with 100 kPa, 400 kPa and 200 kPa for analysis of collapsibility. From the results, it was verified that the soil is collapsible for all flooding stresses. High values of collapse potential were found and the results allowed to do correlations of some parameters using the computer program Wolfram Mathematica 7.0, verifying which function was the most appropriated to the desired correlation

Abstract:
Le milieu interstellaire est un élément essentiel des galaxies. Il est en effet la matrice de la formation des étoiles et des planètes. Il est composé de gaz et de poussières interstellaires. Il est généralement admis que la présence de molécules organiques complexes (COM) est due aux réactions en phase gazeuse. Toutefois, la synthèse de certaines espèces clés (i.e. H2,H2O, CO2, etc.) nécessite l'intervention des réactions en phase solide c'est à dire sur les grains de poussière. Plus de 200 molécules, dont des COM, ont été détectées dans l'ISM. et les enveloppes circumstellaires. Certaines de ces COM contiennent déjà du carbone, de l'oxygène, et de l'azote, qui sont les principaux éléments chimiques de la composition des molécules à partir desquelles la vie terrestre s'est construite. L'objectif de cette thèse est de comprendre les processus physiques et chimiques (diffusion, désorption et réactivité) qui se produisent sur les grains de poussière interstellaire. Plus spécifiquement, ma thèse se concentre sur l’étude de la désorption et de la réactivité des espèces azotées qui peuvent mener à des COM par des processus liés à l'hydrogénation. Toutes les expériences ont été réalisées avec l'expérience VENUS située au laboratoire LERMA à l'université de Cergy Pontoise, France. VENUS est composée d'une chambre à ultra-vide (UHV), appelée chambre principale, dotée d'une pression de base d'environ 10-10 mbar. Des atomes/molécules sont dirigées vers un porte-échantillon dans la chambre UHV au moyen d'un système à quatre faisceaux séparés. La température du porteéchantillon peut être contrôlée entre 7 K à 400 K. Les produits sont sondés par spectrométrie de masse et spectroscopie infrarouge par réflexion en adsorption. Différents environnements ont été utilisés : surface d'or ou substrats de glace d'eau (glace amorphe compacte ou poreuse et glace cristalline) pour imiter les différents environnements astrophysiques. Nous avons procédé à des expériences impliquant certains atomes et molécules comme l'hydrogène, le deutérium, l'oxygène, le CO, N2, NO, H2O, H2O, H2CO, CH3CN et CH3NC. Ces espèces ont été déposées sur une surface froide maintenue à 10 K (et jusqu'à 40 K). CO et N2 ont été déposés sur des substrats de glace d'eau pour étudier les différents comportements des adsorbats ainsi que la distribution des énergies de désorption et le mécanisme de ségrégation. Nous avons étudié l'efficacité de la pénétration des atomes (oxygène et hydrogène) dans la glace d'eau poreuse. Nous avons utilisé le NO comme traceur chimique. A partir de l'analyse de la consommation de NO, nous avons estimé la pénétration des atomes O ou D à travers la glace d'eau poreuse. Nous avons procédé à de nouvelles expériences sur l'hydrogénation du NO et nous avons constaté qu'il existe une barrière d'activation à l'étape HNO + H. Cependant, les atomes H peuvent traverser cette barrière d'activation par effet tunnel sur une surface maintenue à 8 K. Nous avons montré que l'hydroxylamine (NH2OH) est le principal produit de l'hydrogénation du NO à basse température, mais que le N2O est le principal produit à haute température. Nous présentons également les voies chimiques possibles de formation du formamide (NH2CHO) , molécule clé de la chimie pré-biotique, par co-hydrogénation de NO et de H2CO sur une surface froide (typiquement à 10 K). Nous avons analysé et montré l'efficacité de cette voie de formation du formamide sur les grains interstellaires. Nous avons montré que le réseau chimique de l'hydrogénation du CH3CN et du CH3NC est complexe et se fait par différents mécanismes qui sont en compétition. Nous avons mesuré et montré que l'hydrogénation est le mécanisme dominant. De plus, la présence de H2O augmente l'efficacité réactive. De nombreux processus chimiques en phase solide ont été simulés dans le contexte astrophysique de la formation de COM
The interstellar medium is a key component of galaxies which is the matrixof the formation of stars and planets. It is composed of interstellar gas and dust grains. The presence of complex organic molecules (COMs) can be understoodvia reactions in the gas phase. However, the synthesis of some key species (i.e H2, H2O, CO2, etc) needs the intervention of the solid-state reactions on dust grains surface. More than 200 molecules including COMs have been detected in ISMand circumstellar shells. Some of these COMs already contain carbon, oxygen,and nitrogen, which are the main chemical elements in the composition of themolecules on which terrestrial life is built. The aim of this thesis is to understand physical and chemical processes (i.e diffusion, desorption, and reactivity) occurring on interstellar dust grains. More specifically, my thesis focuses on the investigation of desorption and reactivity of nitrogen bearing species that lead to COMs by hydrogenation related processes.All experiments were performed with the VENUS set-up located at the LERMACergy laboratory in the university of Cergy Pontoise, France. VENUS is composedof an Ultra High Vacuum (UHV) chamber, so called the main chamber, with abasis pressure around of 10 −10 mbar. Atoms/molecules were injected onto a sample holder in the UHV chamber through a separated four beamline system. The sample holder is controlled in temperature from 7 K to 400 K. Products are probed by using mass spectrometer and reflection adsorption infrared spectroscopy. Different solid states environments have been used: gold surface or water ice substrates (compact amorphous solid water, porous amorphous solid water, and crystalline ice) to mimic different the astrophysical environments.We proceeded experiments involving some atoms and molecules such as hydrogen,deuterium, oxygen, CO, N2, NO, H2O, H2CO, CH3CN, and CH3NC. These specieswere deposited on the cold surface held at 10 K (up to 40 K). CO and N2 weredeposited on water ice substrates to study different adsorbed behaviours as well as the distribution binding energy and the segregation mechanism. We studied theefficiency of atoms (i.e oxygen and hydrogen) penetration into porous water ice.We used NO as a chemical tracer for the penetration of O and H atoms throughwater ice. From the analysis of the consumption of NO, we estimated the penetra-tion of O or D atoms through porous water ice. We proceed new experiments onthe hydrogenation of NO and found that there is an activation barrier at HNO H step. However, H atoms can cross the activation barrier via quantum tunnelingon the cold surface maintained at 8 K. We indicated that hydroxylamine (NH2OH)is the major product of the hydrogenation of NO at low temperatures, but N2O isthe major product at high temperatures. We also present possible chemical path-ways of the pre-biotic formamide (NH2CHO) through the co-hydrogenation of NOand H2CO on the cold surface (typically at 10 K). Simultaneously, we analysedand discussed the efficient formation route of formamide on interstellar grains. We showed that the chemical network of the hydrogenation of CH3CN and CH3NC iscomplex and takes place via different mechanisms which tend to be competitive.We measured and indicated that the hydrogenation is the dominant mechanism.Furthermore, H2O is always raising the reactive efficiency

Abstract:
A number of alloy bars were manufactured to some very precise specifications. Certain scientific institutions then performed chemical analyses and made several measurements of the content of some chemical elements of interest. The measurements made on each of the alloy bars can be considered a set of repeated measurements. Modelling techniques for repeated measurements are now well established. Many of these techniques are based on the multivariate normal distribution with some specified mean and covariance structure. Modelling of the covariance structure is necessary so that efficient and meaningful inferences may be made about the mean structure. For the example of repeated measurements made on an alloy bar, the set of measurements is assumed to follow a multivariate normal distribution with a mean mu and a covariance structure Sigma. The choice of mu and Sigma is explored. Experiments which produce sets of repeated measurements can quite often result in a large amount of data being collected. This means that the use of statistical techniques to fit the model to the data can become computationally demanding. The use of maximum likelihood estimation is considered. Several aspects of constructing computationally efficient algorithms to maximise the likelihood function of the data are addressed. When the proposed model has been fitted to the data the suitability of the model and its assumptions are investigated. A score test is constructed to assess the correctness of the proposed covariance structure. Normal plots of the standardised residuals are used to assess other possible defects in the model, such as an incorrect assumption of normally distributed data. The work which has been carried out was motivated specifically by experiments where the set of repeated measurements came from a chemical analysis of an alloy material. It is the percentage content of a number of chemical elements which is of interest and the choice of statistical models was made with this in mind. However, it is demonstrated how the statistical techniques and models for the analysis of the chemical data may be used to analyse repeated measurements which arise from other kinds of experiments.

Abstract:
Cette thèse porte sur l'optimisation de la conception et des décisions opérationnelles des laboratoires d'analyses médicales. Dans cette thèse, un outil d'aide à la décision comprenant des modèles mathématiques, un algorithme heuristique et un modèle de simulation personnalisé est développé pour aider les décideurs à résoudre les principaux problèmes stratégiques, tactiques et opérationnels en conception et gestion des opérations des laboratoires d'analyses médicales. Dans cette thèse, la sélection des machines et la disposition des instruments sont étudiées en tant que principaux problèmes stratégiques, le problème de configuration des analyseurs en tant que problème tactique et l’affectation, l’aliquotage et l'ordonnancement en tant que principaux problèmes opérationnels. Un modèle de simulation personnalisé et flexible est développé dans FlexSim pour étudier le laboratoire d'analyse médicale conçu à l'aide des résultats de modèles mathématiques et d'un algorithme de layout développés. Le modèle de simulation aide le concepteur à construire et à analyser un laboratoire complet en tenant compte de toutes les principales caractéristiques du système. Cet attribut de simulation permet d'analyser le comportement du système et de déterminer si le système conçu est efficace. Pour vérifier la validité du cadre proposé, les données extraites d’un cas réel sont utilisées. Les résultats de sortie scellent l'applicabilité et l'efficacité du cadre proposé ainsi que la compétence des techniques proposées pour traiter chaque problème d'optimisation. À notre connaissance, cette thèse est l’une des principales études sur l’optimisation des laboratoires d'analyses médicales
This thesis focuses on the optimization of clinical laboratory design and operating decisions. In this thesis, a decision support tool including mathematical models, a heuristic algorithm and a customized simulation model is developed to aid decision makers for the main strategic, tactical and operational problems in clinical laboratory design and operations management. In this thesis, machine selection and facility layout are studied as the main strategic problems, analyzer configuration problem as the tactical problem, and assignment, aliquoting, and scheduling as the principal operational problems. A customized and flexible simulation model is developed in FlexSim to study the clinical laboratory designed through the outputs of developed mathematical models and layout algorithm. The simulation model helps the designer to construct and analyze a complete clinical laboratory taking into account all major features of the system. This simulation attribute provides the ability to scrutinize the system behaviour and to find out whether the designed system is efficient. Furthermore, simulation model can be fruitful to decide on scheduling, aliquoting and staffing problems through the evaluation of various scenarios proposed by decision maker for each of these problems. To verify the validity of the proposed framework, data extracted from a real case is used. The output results seal on the applicability and the efficiency of the proposed framework as well as competency of proposed techniques to deal with each optimization problem. To the best of our knowledge, this thesis is one of the leading studies on the optimization of clinical laboratories

Buildings, serve in the real world, inevitably acquire or become involved in new proposals of meanings all the time. Their identities and expressions are constantly under scrutiny in the tide of changes. This thesis, through the design of a building extension, intends to explore the art of architectural additions. As the design project, it will reexamine the design of Media Laboratory at Massachusetts Institute of Technology and subsequently proposes a design for the extension to the existing lab. The design of the lab was carried out by I.M. Pei & Partners in collaboration with a group of artists; a design move underlining the basic philosophy of the lab, integration of Arts and Media Technology. The Lab is located at the gateway of the MIT East Campus housing the MIT Council for the Arts, the Media Laboratory, and the List Visual Art Center. While Media Lab's success in producing high-end media technology is readily apparent, its critics still wonders on how much its current physical setting is actually supporting its success. Given the unique task of marrying Arts and media technology under a single roof, the building has, since the first unveiling of its design, coaxed extensive discussion about the design's appropriateness and workability. Not only did its Critics challenged the building's ability to accommodate the intended program, but also its role as a member of the greater MIT community when its introspective plan, a square implying its own center and focus, and defensive exterior appearance, composed mostly of opaque surface, seems to be isolating itself from its context. Furthermore, the lab's recent shift in research agenda from the abstraction of electronic content, the multimedia technology, to the overlapping of this technology with the physical world is posing new challenges to its existing lab layout. A reevaluation and transformation of the building, in the face of these challenges, is inevitable. Prior to proceeding with the design of the extension, some of the questions that this thesis will try to answer are: What are the values and flaws of the existing building. Is there room for improvement architecturally? Is the current lab layout supporting efficiently the various types of activities of the artists and the media scientists? How well is it promoting the collaboration between the artists and the scientists as its founders had intended? How is it supporting its role as the container of one of the premier public facility on campus, the List Visual Art Center? Architecturally, how to add to such a rigid and self-sufficient geometry? Finally, how should the new research agenda be accommodated spatially? The three main methods in conducting this project are: interviews with key informants to understand the value and flaws of the current building, architectural analysis and a study on how labs of this type work. From Urbanistic point of view, the new extension tries to integrate itself with the MIT campus in two-folds; the overall massing geometry of the campus, and the redefinition of public/shared open spaces. The underutilized open space will be activated and internal and circulation modified to best serve the interest of the facility.

The Mechanical Structures Interactive Lab is one of a number of new remotely accessible WebLabs being developed at the Massachusetts Institute of Technology. WebLabs allow students access to physical experiments from anywhere at anytime via the World Wide Web. While these cannot replace laboratories that are more traditional, they facilitate lab assignments when traditional labs are not practical. The Mechanical Structures Interactive Laboratory is a framework for allowing remote experimentation on elastic structures. Users of the system are able to obtain data from experiments they perform on the structures form a remote location. The system is designed to allow new experiments to be easily added, and can support all levels of mechanical structures courses currently oered at MIT. The system can be used by multiple courses in multiple departments of multiple universities. Users are only required to have a computer connected to the World Wide Web and they can send actuator commands and monitor sensor responses in near real time. The typical student is expected to spend between fifteen minutes to an hour using the system to obtain experimental data. A queuing system regulates (and allows monitoring of) system usage. All of the software was developed using National Instruments G language. Unlike similar systems, the Mechanical Structures Interactive Lab does not use any sort of Java based applications. The system has been tested in a small graduate course. The students used a piezoelectric actuator to stimulate a beam and monitored the response using strain gauges, laser displacement sensors and a webcam. By using the same computer to both model the beam and perform experiments, the students received rapid feedback on the accuracy of their numerical models. While most of the feedback received was positive, there are still a number of areas for system improvement. While work is still being done to make these improvements, the system has shown itself to be an effective means of providing a positive educational experience to engineering students.

Abstract:

Turnaround time is a metric most often used to determine a laboratory?s performance. This business project discusses the proposal of a mobile laboratory company called the Mobile Laboratory Unit. The focus of this project is the implementation of a mobile laboratory company that can reduce turnaround time on laboratory results and deliver services at a competitive rate while keeping the integrity and reliability of laboratory results that health care providers are accustomed to receiving. North Orange County businesses are the demographic target and currently does not have an organization such as this, therefore, a company that offers a service such as the Mobile Laboratory Unit would fill a void that is present within this market. Organizations outside of health care companies would be able to use the services of the Mobile Laboratory as well to conduct onsite health screenings and drug tests for students and employees.

Abstract:
Facing a rapidly-changing power industry, the electrical engineering department at Cal Poly San Luis Obispo proposed Advanced Power Systems Initiatives to better prepare its students for entering the power industry. These initiatives call for the creation of a new laboratory curriculum that uses microprocessor-based relays to reinforce the fundamental concepts of power system protection. This paper summarizes a laboratory system fit for this task and presents a set of proposed laboratory experiments to establish a new laboratory course at Cal Poly. The experiments expose students to the capabilities of industry-standard microprocessor-based relays through hands-on procedures that demonstrate common power system protection schemes. Relays studied in this project support transformer, transmission line, and induction motor protection.

Abstract:
The virtual laboratory is divided into two groups. The first group is comprised of a virtual laboratory for simulation. It is mostly used for presentation and demonstration purposes. It is not necessary to install complicated and expensive software for their use. The second group of the virtual laboratory is a long distance measure. Real systems are measured with the help of this laboratory. The advantage of long distance measuring is that data from the measurements are saved directly onto the personal computer and they can be immediately evaluated. In this project the procedure for creating a virtual instrument for long distance measuring is described in the LabVIEW program. LabVIEW is a graphic developmental environment, for the measuring and analysis of data.

University level laboratory work is reformulated to fit into the chemistry and

natural science education in the upper secondary school of Sweden. This thesis

describes how this reformulation is performed both from the chemical and the

didactic point of view. The resulting laboratory manual has been tested by students

in the target group with positive response. Interest lay in how to present

laboratory experiments far different from what they usually did and how it actually

connected to their studies in natural science. How much did attitudes and

self-efficacy influence the implementation of the laboratory work and how did

the students collaborate? The author designed the laboratory work, observed an

implementation of parts of the laboratory work through laboratory lessons in a

school class and made a follow-up interview with the teacher.

The experiments include both in situ water level and velocity measurements and optical visualization of the flow field under a variety of normal-incident wave conditions. Digital video is used to record surface drifters moving through a rip current system. A method is presented that tracks these digitally-recorded drifters into long Lagrangian sequences. The laboratory measurements capture both an Eulerian and Lagrangian description of the rip current system. Time-averaged rip current properties are calculated and analyzed using both in situ and video measurements. From the video, Lagrangian velocities are computed with forward differencing of the low-pass filtered drifter tracks. Wave properties are also estimated using the orbital drifter motions and linear (Airy) wave theory. The effects of various wave conditions on the time-averaged rip current systems are investigated to show that wave height is a critical parameter. Measurements of circulation cells are obtained by spatially averaging the drifter track velocity measurements into a polar grid ranging from 0.25 m to 3.25 m from the center of the cell. Circulation cell features, such as the center of circulation and cell width, are calculated to characterize their response to various wave conditions. Spectral analyses are used to characterize the rip current pulsations in the experimental measurements. Three frequencies are found to be energetic in several of the experiments in the low frequency band: the wave group frequency, a lower frequency, and the interaction of the wave group and lower frequencies. Some experiments have significant energy at each of the three peaks, where others have only one or none. The lower frequency motions have also been found in the video measurements and attributed to rip meandering. Possible causes for the low-frequency pulsations, including wave basin seiching, circulation cell instabilities, and wave-current interaction, are discussed. This thesis adds to previous rip current studies by providing a spatially-large and time-varying perspective of rip current systems as a whole.

Abstract:
Distance education is a growing trend in today’s society. One component, however, that has not been able to be translated well to online learning is the physical experience of a laboratory experiment. Our particular project was to motorize a preexisting optical engineering laboratory experiment so that it could be performed remotely over the Internet anywhere in the world. We engineered this with the goal of providing as much of an in-­‐lab experience as possible hopefully demonstrating the viability of this concept as an educational tool. Ultimately, the project does demonstrate that it is possible to translate physical laboratories to online experiences where the critical concepts of the lab are still effectively learned through the manipulation of a limited selection of the hardware components. However, as a supplement to distance students’ restricted curriculum, this system can be an invaluable learning tool. In the future, this system could be scaled to incorporate more laboratory experiments with the ultimate goal of creating a fully online curriculum.

Abstract:
This project involves the construction of a remote-controlled laboratory experiment that can be accessed by online students. The project addresses a need to provide a laboratory experience for students who are taking online courses to be able to provide an in-class experience. The chosen task for the remote user is an optical engineering experiment, specifically aligning a spatial filter. We instrument the physical laboratory set up in Tucson, AZ at the University of Arizona. The hardware in the spatial filter experiment is augmented by motors and cameras to allow the user to remotely control the hardware. The user interacts with a software on their computer, which communicates with a server via Internet connection to the host computer in the Optics Laboratory at the University of Arizona. Our final overall system is comprised of several subsystems. These are the optical experiment set-up, which is a spatial filter experiment; the mechanical subsystem, which interfaces the motors with the micrometers to move the optical hardware; the electrical subsystem, which allows for the electrical communications from the remote computer to the host computer to the hardware; and finally the software subsystem, which is the means by which messages are communicated throughout the system. The goal of the project is to convey as much of an in-lab experience as possible by allowing the user to directly manipulate hardware and receive visual feedback in real-time. Thus, the remote user is able to learn important concepts from this particular experiment and is able to connect theory to the physical world by actually seeing the outcome of a procedure. The latter is a learning experience that is often lost with distance learning and is one that this project hopes to provide.

Abstract:
The importance of the appropriate timing of parturition is highlighted by the fact that preterm labour accounts for 85% of the deaths of normally formed babies. In addition, there are clinical situations where induction of labour is required. Attempts to reduce the incidence of preterm labour and facilitate induction require an understanding of the normal processes of labour at term. In this thesis the physiology of parturition is considered, with emphasis on prostaglandin biosynthesis and metabolism, and the regulation thereof, processes which are thought to be pivotal in the mechanism of labour. The physical and biochemical changes associated with cervical ripening are discussed, as are mediators of this process. Finally, the current understanding of ovine parturition and potential similarities with humans is reviewed. The laboratory studies described employ the techniques of explant and cell culture of fetal membranes, namely amnion and chorion, to investigate firstly the changes in synthesis and metabolism of prostaglandins E2 and F2a (PGE2, PGF2a) that occur within these tissues in association with labour. Prostaglandin production by amnion is increased without any effect on metabolism by chorion. The effect of amniotic fluid on prostaglandin synthesis and metabolism in cell culture was then explored, and, having demonstrated that amniotic fluid from labouring women stimulates PGE2 and PGF2a production, the mechanisms controlling the response to amniotic fluid were investigated, and found to be dependent on new protein synthesis and protein kinase C. In the clinical situation pharmacological ripening of the cervix was studied in two randomised, placebo-controlled clinical trials. The efficacy of recombinant human relaxin and mifepristone (RU 486) was investigated in women with an unfavourable cervix, modified Bishop score < 4, in whom induction of labour was indicated. Vaginal administration of relaxin (1,2 and 4 mg) was without effect on cervical ripening. The first part of a dose finding study with mifepristone demonstrated that a dose of 50 mg may have some preparatory effect on the cervix with regard to ripening, but that a higher dose is required for successful induction of labour.

Abstract:
Includes bibliography.
The thesis consists of a literature review and a limited experimental investigation in a soils laboratory. The objective of the literature review is to determine what standard laboratory test methods based on vibration exist for the control of compaction, to what soil types these tests are applicable and what the factors are which affect laboratory vibratory compaction. The study revealed that extensive research has been carried out in the USA and Europe, where standard laboratory compaction tests exist for the determination of the maximum dry density of cohesionless, free-draining soil. The US methods are based on the use of a vibratory table, while the European practice is based on the use of a vibratory tamper. No standard tests appear to exist for soil exhibiting cohesion, though limited research has been carried out in the USA into the behaviour of such soils under laboratory vibratory compaction. The factors; frequency, amplitude, mould size and shape surcharge intensity and manner of application, soil type, time of vibration, number of layers and moisture content are all reported to have an effect on the maximum dry density achievable. It has been recognised that significant interaction occurs between the factors affecting vibratory compaction, but the extent of the interaction appears to be only partly understood. The objective of the limited experimental program was to determine whether a specific graded crushed stone could be compacted to Modified AASHTO maximum dry density with a laboratory vibratory compaction technique using a vibratory table, and how this could best be achieved. The effects on dry density of changing the frequency, the time of vibration, mould size, surcharge pressure, grading and moisture content were investigated. It is concluded that the graded crushed stone in question can be compacted to Mod. AASHTO maximum dry density but that before reliable reproducible results can be achieved with this type of test further work is necessary. Such research should be aimed at investigating the interaction effect between the amplitude of vibration, the soil type and the type and intensity of the applied surcharge pressure.

Abstract:
Collapsible soils covers naturally over 10% of the earth’s surface. This makes it a global problem and it is essential that engineers identify and control collapsibility prior to construction. Hence in this thesis, a study on identification, evaluation and control of soil collapsibility is undertaken. Four geologically different soils have been tested at five compactive variables from optimum moisture content (OMC). The soils tested include: Brown inorganic silty clay of low plasticity (A); White inorganic silt with slight plasticity (B); Red inorganic clay of intermediate plasticity (C); and Brown sand-clay mixtures with inorganic clay of low plasticity (D). The soils were each compacted at moisture variations 60% - 80%, 80% - 95%, 95% - 105%, 110% - 125% and 125% - 150% respectively representing ‘Low Dry OMC’, ‘High Dry OMC’, ‘At OMC’, ‘Low Wet OMC’ and ‘High Wet OMC’. The major causes of collapsibility of soil and the geomorphological processes that gives the pedogenesis of collapsible soils, is highlighted and great emphasis is placed on the adverse effect of collapsible soils. The experimental results from particle size distribution, Atterberg, compaction, triaxial and double oedometer tests showed that the soil’s percentage fine with the fines material (silt or clay), coefficient of uniformity, optimum moisture content, Atterberg limits, and stress-strain properties affect the metastability of the soils and they can be compared to the soil’s collapse potential when pressures and moisture content are applied on the soils. Results obtained showed that the soil’s collapse potential is directly proportional to 1) percentage fines, 2) the difference between the silt and clay percentage, 3) the Atterberg limits (liquid limit, plastic limit and plasticity index), and 4) internal friction angle; and inversely proportional to 1) coefficient of uniformity, 2) initial moisture content, 3) cohesion and finally 4) peak deviator stress. Each soil’s geological property proved to have an adverse effect on the metastability of the soils especially the dry of optimum moisture content. The most interesting results were obtained from the oedometer test. Results of the critical pressure varied with each soil and their compactive variable; Most of the soils at their ‘dry OMC’ had the highest collapse potential. In general, the lower the critical pressure the higher the collapse potential of the soil. The experimental data obtained herein were checked with the past research collapse indexes and found the results agreeing with just two research work out of eighteen examinations. Finally models for identifying soil collapsibility are generated with relationship between parameters from sieve, Atterberg, proctor compaction and triaxial. Laboratory data and data from twelve research work were used to verify the models and they show that the models work. After the verification of these formulas with past research data collected, the best models were three compactive variable models. The models give a collapsibility index in terms of percentage fines, initial moisture content, initial degree of saturation and initial dry density.

Abstract:
The deepening and maintenance of the world's ports and navigable waterways has been an integral part of the world economy for centuries. In recent years, cutterhead and draghead hydraulic suction dredges have performed a majority of the dredging work. The ongoing design and testing of hydraulic dredges is important for maintaining efficient dredging operations within the limits set by increasing environmental regulations. The high cost of building and operating a hydraulic dredge makes field testing of full-scale prototypes very expensive and time consuming. Moreover, the testing conditions are generally difficult to control, and the natural unpredictability of the sea can render experimental results inconclusive. These factors substantiate the need for laboratory model testing of hydraulic dredging operations. The usefulness of any hydraulic model depends on the degree of geometric, kinematic, and dynamic similarity between the model and its prototype. The primary challenge in establishing useful similitude criteria for model dredge studies is proper kinematic scaling of the suction inlet velocity, average particle settling velocity, dredge swing velocity, and cutter rotational speed. Despite the inherent challenges, model studies of hydraulic dredge equipment have proven useful for obtaining qualitative results. The new Coastal Engineering Laboratory at Texas A&M University is equipped with model dredge testing facilities ideal for performing such experiments. The tow/dredge carriage has a fully adjustable dredge ladder, a 14.9 kW (20 hp) cutter drive, and a 2.54 cm (3 in) dredge pump. A Programmable Logic Controller (PLC) provides computer numerical control and real-time data collection and analysis during model dredging operations. The purpose of this thesis is to investigate scaling relationships for hydraulic dredge model studies and to design a model dredge carriage for the new laboratory facilities recently constructed at the Texas A&M University College Station campus. Pursuant to the design of the new dredge modeling facilities, a rationale for scaling the model dredge operating parameters based on previous model studies is put forward. Examples of model studies that could be performed with the proposed facilities are discussed as well as how the scaling methodology is applied to each experiment to allow the quantitative interpretation of experimental data.

Abstract:
At the beginning of the twenty-first century, the term 'theatre laboratory' has entered the regular lexicon of theatre artists, producers, scholars and critics alike. However, use of the term is far from unified, often operating as an overarching referent for a web of intertwining practices, territories, pedagogies and ideologies. Despite numerous studies on individual practitioners and practices, there is a noticeable gap in scholarship on the theatre laboratory itself. The aim of this present study is therefore to refine the currency_ of the term's contemporary usage through an investigation of the organisational structures of the theatre laboratory as they have developed in Russia. Russian theatre provides a clear emergence of laboratory practice that can be divided into two distinct organisational archetypes: the studio and the masterskaya. These archetypes have roots in Russian culture and history but can be extrapolated into other cultures as they inform the basic structures for organising approaches to work. Scholarship investigating the history of the science laboratory and the painter's studio has uncovered similar archetypes. Uniquely drawing upon the field of laboratory studies. this thesis reveals a complex history of the laboratory's characteristics and functions that support the term's use in theatre. Although discursive in approach and historical in its scope, the present study has been informed substantially by contemporary practice. The characteristics of each archetype have been identified through interviews with. and examinations of, contemporary practitioners including Slava Polunin, Anatoli Vassiliev, Sergei Zhenovach and Dmitry Krymov, none of whom are well-known in English-language scholarship. Likewise, the majority of Russian texts consulted for this study have rarely been used in English, being recently published archival material, doctoral theses, or press articles. Combining a range of scholarship with examples of contemporary practice, this thesis aims to refine conceptions of the term theatre laboratory.

Abstract:
Retiring baby boomers and the lack of interest and awareness among college students to enroll in an accredited Clinical Laboratory Science (CLS) program have created a shortage of CLS professionals in the 21st century. The U.S. Bureau of Labor Statistics predicts 18,000 CLS vacancies by 2018. However, only about 5,000 students graduate from accredited CLS programs each year. The purpose of this study was to explore students' perceptions of allied health professions and factors that influenced students and CLS professionals to select CLS as a profession. Bandura's social cognitive career theory served as the theoretical framework for this phenomenological study. Convenient purposeful sampling was used to select the 7 CLS professionals, 5 high school students, and 5 college students in the Chicago area. Participants took part in either a 30- to 60-minute group session or a 45- to 90-minute semi structured interview. Qualitative analysis included open axial coding to identify emerging patterns and themes from the transcripts. Findings revealed that the perceptions of both high school and college students' knew little about the CLS profession, and factors influencing CLS as a career choice included interests in science, health care, and family. CLS professionals indicated their interests in science and a high demand for CLS services in the workforce led them to pursue careers in the field. Implications for social change include improving professional-development programs for student awareness of allied health professions and mitigating the shortage of clinical laboratory scientists.
