The objective of this study was to evaluate response times of a salinity sensor and a soil psychrometer. Influences of pressure, temperature and molar concentration changes were to be measured. Salinity sensor response times ranged from 50 to 130 minutes during solution adsorption while desorption response times were perhaps ten times as long. Temperature affected both response times and equilibrium values, but pressure did not affect either. Soil psychrometer response times ranged from from 40 to 80 minutes for either adsorption or desorption of solution. However, other factors probably related to indirectness of measurement made the soil psychrometer fail to reflect osmotic potential. Both pressure and temperature effects were significant. Comparisons between hypothetical soil water infiltration times and sensor response times together with soil psychrometer failure led to the conclusion that the salinity sensor may be useful while the soil psychrometer would probably not be useful for the return-flow water quality control.

An exploratory analysis of the trihalomethane (THM) and haloacetic acid (HAA) formation potential (FP) of Cedar Lake in order to produce formation potential curves for both THM and HAA; determine the THMFP and rate constant and compare to previous studies on Cedar Lake; and develop modeling for the formation potential loss of HAA from laboratory analysis of the raw lake water. While extensive modeling approaches have been explored for THM formation on different water sources, not many have been applied to the reservoir that supplies water to the Carbondale Water Treatment Plant and even fewer have explored the formation and modeling of HAA. Data for this study was obtained through laboratory experiment by applying bleach as a substitute for free chlorine to raw water samples obtained from Cedar Lake and quenching the samples at specific time steps to stop the reaction. Samples were then analyzed for THM content using standard method EPA 524.2R4.1 and HAA content using standard method EPA 552.2. The observed peak formation was 641.2701 µg/L for THM and 426.8 µg/L for HAA, but modeling fitted to the laboratory results indicated that a lower FP provided a better fitting of the data. A detailed analysis of the formed THM and HAA compounds indicated that a model produced for each compound resulted in more appropriate fitting by being able to account for the differing reaction rates and limiting factors of each reaction.

A surface characterisation of the Arnager Greensand in south Sweden, a deep saline aquifer found to be suitable for geological storage of CO2 or energy storage, was undertaken in this thesis. Vintage seismic reflection data only available as scanned tiff images of the final stacked sections were digitized and processed using modern interpretation software to provide new insights into the morphology of the Arnager Greensand and to analyse the reservoir’s potential as an energy storage unit. The primary energy storage method discussed and evaluated was Compressed Air Energy Storage (CAES). This is a modern energy storage method developed as a tool for regulating inherently intermittent renewable energy sources. Such methods are key to the growth of the renewable sector and for providing a competitive alternative to fossil fuels. Moreover, in comparison with other energy storage methods such as battery storage, CAES is known to have strong potential to deliver highperformance energy storage at large scales for relatively low costs compared with any other solution. Previous studies conducted in the 1980’s by Swedegas produced a 2D isochrone surface map of the Arnager Greensand by hand interpolation methods utilizing analogue data collected by Oljeprospektering AB (OPAB, currently Svenska Petroleum). The Geological Survey of Sweden (SGU) has now transferred a vast amount of the historical OPAB dataset to modern digital format. This thesis contributes to those efforts and seeks to find new interpretations from the vintage data. A more comprehensive 3D model of the top of the Arnager Greensand employing the application of modern interpretation software was produced in this study. Strong similarities between morphology and dip-trend have been observed between the surface model generated in this report and the historical Swedegas isochrone surface map. Reservoir properties such as thickness, porosity and permeability gleaned from the earlier reports show the Arnager Greensand to exhibit excellent potential as a storage unit. Preliminary effective capacity estimates by Nordic CCS Competence centre show the Aranger Greensand to be one of the top three storage aquifers in Sweden. These positive appraisals highlight the need for a better characterization of the Aranger Greensand through data digitization and modern interpretation means. This thesis contributes to that endeavour.

Previous literature has suggested that creative students often have difficulties adapting to academic and social contexts, even if they are intellectually gifted (Goertzel & Goertzel, 1960; Kim, 2008). Creative individuals' difficulties in social adaptation can be explained better by introducing the concept of self-regulation, since self-regulation has been found to be a strong predictor of one's academic success, school engagement, and peer social acceptance (Duckworth & Seligman, 2005). Thus, the purpose of this study was to investigate the relationship between creative potential and self-regulation among gifted young adults. In addition, this study aims to examine the moderating effects of parenting styles on that relationship. Participants in this study were 311 high achieving students who participated in the Honors Program at the Midwestern University. Their creative potential was assessed by the Runco Ideation Behavior Scale (Runco, Plucker, & Lim, 2001). Results showed that there was no relationship between creative potential and short-term self-regulation. However, creative potential was positively related to the long-term self-regulation of gifted young adults after controlling the effect of gender and semester in the college/university, although it was a small correlation (partial r=.132, p Findings from this study refute the position that gifted individuals' creative potential may relate negatively to their self-regualtion capacities Findings also suggest that authoritative parenting can nurture children's long-term self-regulation without hindering creative potential development.

Observational studies are an indispensable complement to randomized clinical trials (RCT) for comparison of treatment effectiveness. Often RCTs cannot be carried out due to the costs of the trial, ethical questions and rarity of the outcome. When noncompliance and missing data are prevalent, RCTs become more like observational studies. The main problem is to adjust for the selection bias in the observational study. One increasingly used method is propensity-score matching. Compared to traditional multi-covariate matching methods, matching on the propensity score alleviates the curse of dimensionality. It allows investigators to balance multiple covariate distributions between treatment groups by matching on a single score. This thesis focuses on the large sample properties of the matching estimators of the treatment effect. The first part of this thesis deals with problems of the analytic supports of the logit propensity score and various matching methods. The second part of this thesis focuses on the matching estimators of additive and multiplicative treatment effects. We derive the asymptotic order of the biases and asymptotic distributions of the matching estimators. We also derive the large sample variance estimators for the treatment effect estimators. The methods and theoretical results are applied and checked in a series of simulation studies. The third part of this thesis is devoted to a comparison between propensity-score matching and multiple linear regression using simulation.

Due to population expiation and the increased awareness of the impact on the environment by wastewater treatment, improved wastewater treatment systems are needed to treat municipal and agricultural wastewater. Treating wastewater with oxygen decreases carbon compounds at the expense of energy to move carbon and oxygen to be in contact with each other. Anaerobic digestion of wastewater can reduce the cost by utilizing microbes to treat high amounts of carbon in wastewater without the need for extensive oxygen requirement. With a proper balance of nutrients, microbes also produce methane, a renewable energy source. It has been suggested that microalgae be utilized to help balance the nitrogen content of wastewater for treatment by microbes. One challenge with the use of algae is the initial breakdown of algae cells. Using a digester with microorganism that can produce methane and decompose algae could enhance production of methane from the digestion of algae. The combination of wastewater, which is high in carbon content relative to nitrogen, with algae, which is high in nitrogen, could provide the balance needed for the microbes to treat wastewater and provide methane. A biomethane potential test was used to compare the ability of two microbe communities, facultative lagoon sediment and anaerobic digester sludge to digest algae. Each microbe community treated dairy, swine, municipal, and petrochemical wastewater augmented with algae and acetate. The ability to degrade augmented wastewater and produce methane was determined by measuring the volume and composition of biogas produced over time. Both treatments were successful in production of methane. Facultative lagoon sediment showed more methane produced per carbon dioxide than anaerobic digester sludge.

La réalité clinique que nous rencontrons dans un cadre psychanalytique classique ou lors desséances psychanalytiques nous amène, souvent en premier-plan, des moments où les patientsutilisent ce cadre comme un instrument de construction, une construction qui se réalise dans lenégatif de la relation avec le psychanalyste, comme une tentative de recréer la « formeoriginaire ». Il s’agit des moments dans lesquels le patient amène dans la situation analytique desformes de manifestation des expériences archaïques ou du potentiel traumatique, des formesappartenant à un espace-temps non psychisé, potentiel, un temps qui garde l’actualité de sesexpressions suite à un manque traitement, d’élaboration de ses contenus.J’ai commencé en partant des deux hypothèses suivantes :L’apparition violente des éléments archaïques ou celle du potentiel traumatique dans la situationanalytique représente une forme de manifestation de l’actuel, qui n’a pas la forme élaborée d’unemétaphore, ni la forme primaire de la représentation, mais une forme archaïque, inaccessible à lapsychisation, dans une forme semblable à la présentation, Darstellung, qui aspire à la représentation,c’est-à-dire à une transformation dans une forme accessible aux processus primairesd’élaboration.Au moment où les expériences archaïques et le potentiel traumatique pénètrent violemment lasituation analytique avec des réalités archaïques en répétant un actuel qui est en dehors du tempspsychique de celui des patients, ceux-là ils veulent vivre et se trouver un Ici et Maintenant.Chacun des cas présentés dans cette thèse représente des expériences qui ont tout d'aborddémarrées de l'exploration du potentiel de chaque situation clinique à part. Le cadrepsychanalytique, le cadre de l'analyse avec les enfants institutionnalisés ou le cadre desconsultations psychanalytiques avec les couples mère-enfant offrent une potentialité spatiotemporelledans laquelle la dynamique relationnelle bénéficie d'un espace et temps desexpressions flottantes et associatives. Ce processus de la libre dynamique des contenus amenéspar les patients et celle des formes dont je les ai reçues et élaborées ces contenus ont représentél'accès à cette expérience d'ici et maintenant qui nous a porté vers ce qui a finalement représentéla solution de sortie de l'impasse et celle de continuer les processus de transformation. / The clinical situations we encounter within the classic psychoanalytical setting during thepsychoanalytic sessions bring us, often in foreground, moments when the patients use the settingas a construction tool, a construction that is developed in the negative of the relationship betweenthe patient and the psychoanalyst, as an attempt to recreate the "original shape". These are themoments in which the patient brings within the analytic situation different forms of expression ofthe archaic experiences or of the traumatic potential, forms coming from a space-time nonintegrated,a time that keeps the actuality of his expressions due to an not-enough elaboration ofits contents.I started on the basis of the following hypothesis:The violent appearance of the archaic elements or of the traumatic potential within the analyticsituation is a form of manifestation of the actual, which has not been developed the form of ametaphor, nor the primary form of representation, but an archaic form, inaccessible to thesymbolization process, in a shape similar to the presentation, Darstellung, which aspires to representation,that is to say, to a transformation in a form accessible to the primary developmentalprocesses.. When the archaic experiences and traumatic potential violently penetrate the analytic situationwith archaic realities repeating an actual that is outside of the psychic time of the patients, thosethey want to live and be a Here and Now.6 Each of the cases presented in this thesis represents experiences that first started to explore thepotential of each clinical situation at hand. The psychoanalytic setting, the setting of the analysiswith institutionalized children or the setting of the psychoanalytic consultations with the motherchildcouples, offer a spatiotemporal potentiality in which the relational dynamics benefit from aspace and time in a floating and associative expression. This process of free dynamic contentbrought by patients together with the forms in which I have received and developed such contentopened the access to the experience of the here and now, bringing us to what eventuallyrepresented the solution exit from the impasse and that continue the developing andtransformation process.

<p>Tidigare forskning har visat på att konkurrensen kring talangfulla medarbetare aldrig förr varithårdare och att ha strategier för att behålla dessa blir därför viktigt. En strategi som syftar till att görajust detta är talent management. Men hur arbetar man med detta och vilka föreställningar kringfenomenet finns? Vilka faktorer kan finnas som hindrar och/eller möjliggör arbetet med talentmanagement? För att ta reda på detta har det i studien valts att göra en fallstudie där data samlats ingenom semistrukturerade intervjuer. Det framkommer i studien att talent management upplevspositivt då det ger erkänsla och uppskattning. Dock är det viktigt att det finns en tydligkommunikation så att tanken kring vad satsningen ska leda till och att förväntningarna är tydliga.HR-avdelning, chefer och talanger har alla ett ansvar för att talent management ska bli en strategi föratt få talangfulla medarbetare att stanna kvar i företaget.</p>

<p>This project considers an evaluation of a potential site for a small hydropower plant located in the BioBio north irrigation system, Chile. The purpose was to analyze the potential and constraints in harnessing the energy of an existing infrastructure of irrigation canals for electrical production. The site was analyzed technically, economically and managerially. Before this project nothing was done and therefore the investigations are a main part of the project. A preliminary design for the plant was proposed and the project was named the Minicentral Quillaileo-Mininco.</p><p>Investigations showed a flow variation of 1.62-2.2 m³ per second and a gross head of 44.3 meters. Evaluation gave a possible capacity of 840 kW producing 5 800 MWh annually. Appropriate electromechanical equipment is a Francis turbine with a diameter of 0.5 meter directly coupled to a 1000 rpm synchronous generator. The penstock recommended is a DN 1200 Flowtite GRP. The station is to be fully automatic and connected to the national grid.</p><p>The revenue is based on analysis of the past three year’s electrical market. The costs are based on budget proposals, statistical values and local comparisons. The economical analysis, based on a discount rate of 12% and life span of 35 years, gives a positive cash flow within eight years and a simple payback period of 5 years. The project will have a NPV value of 444 900 USD, IRR 14.70% and B/C of 1.2. Cost per kW will be 2 980 USD. The project is recommended to be further developed.</p>
