Full textAbstract:
Kerb (Pronamide) is often ineffective when it is leached below germinating weed seeds with sprinkler irrigation. Efficacy can be improved by making delayed aerial applications after the sprinklers have been started and before weeds have become established. Tests were conducted to determine the optimal time of application. Optimal times varied with the season and ranged from two to three days after the sprinklers had started during the early season (Sept.) to five to six days during the late season (January).

Full textAbstract:
Three tests were conducted to compare delayed applications of Kerb applied by air with those applied through the sprinklers. Early (6-5-02) season and mid (10-20-02) applications made through the sprinklers were significantly more effective than those applied by air. The late season (11-17-02) application was made too early and the weed control was poor demonstrating the need for proper timing regardless of the application technique. It was concluded that chemigation can be an effective technique for making delayed applications of Kerb to lettuce in the low deserts.

Full textAbstract:
The potassium efflux systems KefB and KefC may be targets for novel antibiotics. The kefC gene has been cloned and molecular analysis on the KefC protein has begun. The yabF gene, which lies directly upstream of the kefC gene on the E. coli chromosome, is required for KefC activity. The aims of the project were to characterise the physiological role of KefB, to clone the KefB gene, and to initiate molecular studies on the regulation of KefB activity. In the course of these studies, it has been shown that; 1. KefB and KefC do not afford protection against all electrophiles since they do not afford protection against the electrophile iodoacetate; 2. KefB and KefC can be partially activated by electrophiles, without the formation of a glutathione-adduct. However, complete activation of KefB and KefC requires the formation of a glutathione-adduct; 3. There may be more than one site for direct activation of KefB and KefC; a periplasmic and a cytoplasmic site; 4. The KefB protein is homologous to the KefC protein, the amino-terminal domain spans the membrane between six and twelve times and the carboxy-terminal domain is cytoplasmic; 5. KefB, for full activation, requires the ancillary protein YhaH, a YabF homologue. YhaH and YabF are involved in the regulation of KefB (and possibly KefC), but, for activation, each is specific for its own system, i.e. only YhaH activates KefB and only YabF activates KefC. Based upon this work, an updated model for the different states of KefB and KefC has been proposed, the involvement of the YhaH and YabF proteins are discussed and molecular studies on KefB have been initiated.

Full textAbstract:
Five tests were conducted to compare delayed applications of Kerb applied by air with applications made through sprinklers. Applications were made commercially to plots ranging in size from 11 to 18 acres. Broadleaf weed control was better in all tests from the sprinkler applied Kerb than from aerial application. The control of volunteer sudangrass was poor in one test from both types of applications and worse from the sprinkler than the aerial application. It was concluded that applying Kerb though sprinklers to lettuce is effective and often superior to aerial applications.

Ulian, Benitez Suzana. "Function of Kek-6 and DNT2 in structural synaptic plasticity in Drosophila." Thesis, University of Birmingham, 2018. http://etheses.bham.ac.uk//id/eprint/8440/.
Full textAbstract:
The Drosophila nervous system undergoes structural synaptic plasticity, however, the mechanisms that govern such event are little understood. Structural synaptic plasticity in mammals is regulated by the neurotrophin brain derived neurotrophic factor (BDNF) and its receptor, tropomyosin receptor kinase full length (TrkB-FL). TrkB-FL has a tyrosine kinase domain (TyrK) intracellularly, that is required for its function in structural synaptic plasticity. Trk receptors have long been sought in Drosophila to verify mechanisms of structural synaptic plasticity, but they have not been found. Later, the Kek receptor family was identified as the kinaseless-Trk homologues in flies (Mandai et al., 2009, Bishop, 2013). Here, I validated that Kek-6 is a neurotrophin receptor for DNT2. DNT2 is a novel retrograde factor at the neuromuscular junction (NMJ), and both DNT2 and Kek-6 regulate structural synaptic plasticity. Kek-6 functions in concert with Toll-6. DNT2 and Kek-6 function upstream of CaMKII and Vap33A at the NMJ synapse. Finally, I show that Kek-6 can regulate intracellular levels of calcium in larval motorneurons. In conclusion, I identified a novel mechanism of structural synaptic plasticity in flies that is independent of a TyrK domain. If there are conserved mechanisms, this may also shed light on how truncated Trks function in the adult mammalian brain.

Full textAbstract:
Aux futurs collisionneurs linéaires et circulaires, la présence d’un halo autour du faisceau est susceptible de fortement limiter les performances, et peut également activer, voire endommager, les composants de l’accélérateur. Le halo doit par conséquent est contrôlé par un système de collimateurs efficace. Pour évaluer l’impact sur les expériences de physique des particules ainsi que les efficacités de collimation, une bonne compréhension des mécanismes physiques générateurs de halo est essentielle, pour par exemple prédire les distributions de probabilité de manière fiable. Pour ce faire, une investigation systématique ont été menée à l’Accelerator Test Facility (ATF) du KEK dans le cadre de cette thèse, d’abord à travers une analyse théorique des principales sources de halo dans ATF, puis moyennant le développement et l’implémentation de diagnostiques dédiés aux mesures du halo, dont les résultat sont ensuite présentés et comparés aux prédictions théoriques. Le halo produit par la diffusion des particules du faisceau sur les noyaux des molécules du gaz résiduel dans la chambre à vide (« Beam Gas Scattering » - BGS) est d’abord estimé analytiquement, avec certaines approximations, puis moyennant une simulation Monte-Carlo. Un nombre considérable de particules de halo BGS est prédit, ainsi qu’une dépendance dans la pression de gaz résiduel. Pour étudier la possible formation d’un halo par le mécanisme de diffusion intra-paquet à grand angle dit de « Touschek » en présence d’une dispersion optique résiduelle, le taux de cette diffusion a été estimé en fonction de plusieurs paramètres faisceau pertinents. Une simulation Monte-Carlo de la diffusion intra-faisceau à petit angle (IBS) et de « Touschek » est aussi en cours de développement. Pour tester les prédictions théoriques, les performances d’un détecteur de halo déjà existant basé sur un capteur diamant ont été améliorées moyennant une technique de repondération qui a permis d’en augmenter la gamme dynamique jusqu’à 10⁵. Afin de disposer d’un instrument complémentaire pour mesurer le halo, un moniteur YAG/OTR a aussi été conçu, construit et installé dans la ligne d’extraction d’ATF. Il a pu être montré que la gamme dynamique et la résolution de ce moniteur YAGOTR sont, respectivement, autour de 10⁵ et inférieure à 10 μm. Grâce aux diagnostiques développés pour mesurer le halo du faisceau d’ATF, les distributions transverses et en énergie ont pu être étudiées. L’accord satisfaisant obtenu entre les prédictions théoriques et les mesures, ainsi qu’une dépendance importante dans la pression de gaz résiduel, ont permis de montrer que la distribution verticale du halo est dominée par le mécanisme BGS. Par contre, la distribution horizontale est bien supérieure aux prédictions BGS, et est par ailleurs asymétrique. L’asymétrie observée peut être en partie reliée à la qualité du champ de l’élément pulsé servant à l’extraction du faisceau d’ATF, ainsi qu’à certaines aberrations dans le transport optique. La distribution de probabilité du halo en fonction de l’énergie a par ailleurs pu être mesurée, grâce à une technique nouvelle d’ajustement de la dispersion optique dans le plan vertical, et a été trouvée compatible qualitativement avec le mécanisme de diffusion « Touschek ». Un scénario plausible de génération du halo dans le plan horizontal a ainsi pu être suggéréAt future linear and circular colliders, beam halo can strongly limit machine performances, cause as well component damage and activation, and should, therefore, be controlled by an efficient collimation system. To evaluate the impact on particle physics experiments and collimation efficiencies, a clear understanding of beam halo formation mechanisms is essential, e.g., to predict halo distribution reliably. For this purpose, systematic investigations have been carried out at the Accelerator Test Facility (ATF) of KEK. In this dissertation, the theoretical analysis of the primary halo sources at ATF and the development of dedicated halo diagnostics are presented. Measurements of beam halo at ATF are also described and compared with the theoretical predictions. Beam halo arising from Beam-Gas Scattering (BGS) in the damping ring was firstly estimated through analytical approximations and a Monte Carlo simulation. A considerable amount of halo particles generated by BGS and the corresponding vacuum dependence have been predicted. To explore the probability of beam halo formation from Touschek scattering in the presence of dispersion, the Touschek scattering rate was estimated with respect to relevant beam parameters. Furthermore, a Monte Carlo simulation of Intra-Beam Scattering (IBS) and Touschek scattering is under development. To probe the theoretical predictions, the performance of an already existing diamond sensor detector was optimized via a data rescaling technique to increase the dynamic range to 1×10⁵. For a complementary diagnostics of beam halo, a YAG/OTR monitor was also designed and installed in the extraction section of ATF2. The dynamic range and resolution of the YAG/OTR monitor have been shown to be around 1×10⁵ and less than 10 μm, respectively. Thanks to the halo monitors developed at ATF2, the transverse halo and momentum tail have been studied. Satisfactory agreement between numerical predictions and measurements as well as a significant vacuum dependence indicate that the BGS process dominates the vertical halo. On the other hand, the horizontal halo appeared to be higher than the prediction from BGS, and moreover asymmetric. The observed asymmetry was shown to be related to the quality of the extraction kicker field and optical aberration. Finally, the momentum tail was for the first time observed by implementing a novel scheme of vertical dispersion adjustment and was found to be qualitatively consistent with the presence of Touschek scattering. A possible scenario for horizontal beam halo formation from Touschek scattering was also suggested

Ferguson, Gail P. "A physiological function for the KEFB and KEFC systems of Escherichia coli in protection against methylglyoxal." Thesis, University of Aberdeen, 1994. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.240013.
Full textAbstract:
The work presented investigates the physiological function of the Escherichia coli potassium efflux systems, KefB and KefC. We have found that these systems are activated during the glutathione-dependent metabolism of the naturally-occurring electrophile, methylglyoxal. KefB was found to be the major system involved; the KefC system was found only to play a minor role. We proposed that one or both of the glutathione metabolites, hemithiolacetal and S-lactoylglutathione, formed during the glutathione-dependent metabolism of methylglyoxal is an activator of the KefB and KefC systems. The activation and activity of the KefB and KefC systems was found to protect cells against methylglyoxal. Cells that lack the KefB and KefC systems or cells that are unable to release potassium, by the KefB and KefC systems, due to the presence of external potassium exhibit a drastically-increased sensitivity towards methylglyoxal. The KefB and KefC systems afford protection against both exogenously-added and endogenously-synthesized methylglyoxal. However, these systems only delay the onset of the death phase against the continuous production of endogenously-synthesized methylglyoxal. Consistent with the efflux data, KefB was found to be the major system involved in the protection, although the KefC system did confer some limited protection. Thus, we proposed that the KefB and KefC systems have a physiological function in the protection of cells against naturally-produced methylglyoxal. The exact mechanism by which the KefB and KefC systems confer protection against methylglyoxal is at present unknown. Preliminary weak acid experiments have provided strong evidence that if potassium release by the KefB and KefC systems is accompanied by acidification of the cytoplasm then acidification might be responsible for part or all of the protection observed.

Full textAbstract:
Thesis (MEng)--Stellenbosch University, 1994.ENGLISH ABSTRACT: Various aspects affecting the inlet capacities of modified stormwater kerb inlets were investigated. Investigations centred on the influence of effective inlet length, ratios of upstream transition section length to inlet section length and road crossfall. The suitability of existing design curves for use in the design of modified kerb inlets was verified and new more "user-friendly" design curves were developed. Attempts were made to develop a sound theoretical model to predict inlet capacities for stormwater kerb inlets as the lack of such a model had previously been identified as a major shortcoming in the design of stormwater kerb inlets. A detailed study of relevant literature and of various full scale model test results confirmed the fact that the effective inlet length is the most important variable affecting the inlet capacity at stormwater kerb inlets. Model studies on various combinations of transition section lengths and inlet section lengths have indicated that in the case of supercritical flow the inlet capacity of stormwater kerb inlets is not sensitive to changes in the ratio between the inlet section length and the upstream transition section length. Furthermore no marked effect on the inlet capacity of a modified stormwater kerb inlet was detected when the road crossfall was increased from 2% to 3%. The inlet capacities predicted by the existing design curves were found to be consistent, although on the conservative side, when compared to the inlet capacities obtained from the full scale model tests. New design curves derived from the existing design curves were developed to provide a less cumbersome procedure in the design of stormwater kerb inlets. The development of an improved comprehensive theoretical model based on pure hydraulic principles was not possible due to the extremely complex nature of flow conditions at stormwater kerb inlets. The most important findings emanating from this research project are: - The confirmation of the "effective inlet length” concept, whereby a part of the expensive inlet section is replaced by an equivalent length of inexpensive transition section upstream of the kerb inlet. which does not affect the inlet capacity of the kerb inlet negatively and thereby results in a substantial saving in the cost of stormwater kerb inlets. - Model tests revealed that for supercritical flows the upstream transition section can be made up to 6 times longer than the inlet section with a maximum length of 6m. without any negative effect on the inlet capacity of the kerb inlet. Similarly an analysis of previous research results has indicated that even in cases of subcritical flow the upstream transition section can be made twice the length of the inlet section. - The full scale model tests also indicated that an upward adjustment of 30% in the inlet capacities as predicted by the existing design curves was justified. The modified design curves proved to be suitable for the design of conventional stormwater kerb inlets as well as for modified stormwater kerb inlets where part of the inlet section is replaced by a transition section. A new set of "easy to use" design curves was developed specifically for urban applications. - Guidelines for determining upstream transition section lengths were drawn up for use in conjunction with the existing and new design curves for the design of stormwater kerb inlets.
AFRIKAANSE OPSOMMING: Verskeie aspekte wat die inlaatkapasiteit van verbeterde randsteeninlate belnvloed is ondersook. Die belangrikste aspekte wat ondersoek is, was die invlood van effektiewe inlaatlengte en die moontlike verhouding van die stroomop oorgangslengte tot die werklike inlaatlengte sowel as dwarshelling. Die ontwerpgrafieke wat tans gebruik word om randsteeninlaatlengtes te bepaal is ook ondersoek aan die hand van modeltoetse op volskaalse modelle om die grafieke se akkuraatheid te toots. Meer gebruikersvriendelike ontwerpgrafieke is ook ontwikkel. 'n Belangrike tekortkoming tot op datum, naamlik 'n geskikte teoretiese model om die inlaatkapasiteit van randsteeninlate te beskryf, is aangespreek. 'n Voorvereiste vir so 'n model was dat die model gebaseer moes word op suiwer hidrouliese beginsels. Die bestudering van vorige navorsing asook die uitvoering van verskeie modelstudies op volskaalse randsteeninlate het die effektiewe inlaatlengte as die belangrikste veranderlike wat die inlaatkapasiteit van randsteeninlate bepaal geYdentifiseer. Tydens tootse uitgevoer op volskaalse modelle onder superkritiese vlooitoostande met verskillende kombinasies van oorgangslengtes en inlaatlengtes, vir die dieselfde totale lengte het dit geblyk dat die inlaatkapasiteit grootliks onatbanklik is van die verhouding van die oorgangslengte tot die inlaatlengte. Vit die modeltootse het dit oak geblyk dat paddwarsval 'n baie beperkte invlood op die inlaatkapasiteit van ransteeninlate gehad het toe die paddwarsval verander is van 2%na 3%. Die resultate wat verkry is uit die modeltoetse het ook aangetoon dat die bestaande ontwerpgrafieke konserwatief is in hul voorspelling van inlaatkapasieit van randsteeninlate. Die bestaande ontwerpgrafieke is voorts gebruik om nuwe meer gebruikersvriendelike ontwerpgrafieke te ontwikkel. Die ontwikkeling van 'n teoretiese model am inlaatkapasiteite volledig te voorspel was egter nie moontlik nie vanwee die uiters komplekse aard van die vloei by randsteeninlate. Die belangrikste bevindinge van hierdie studie kan soos volg opgesom word: - Afdoende bewyse is gevind dat die "effektiewe inlaatlengte" konsep, waarvolgens 'n gedeelte van die duur inlaatgedeelte met 'n goedkoper oorgangsstuk van dieselfde Iengte vervang kan word sonder om inlaatkapasiteit in te boet, weI suksesvol aangewend kan word om kostes in die ontwerp van stOlIDwater randsteeninlate te bespaar. - Afdoende bewyse is gevind dat die "effektiewe inlaatlengte" konsep, waarvolgens 'n gedeelte van die duur inlaatgedeelte met 'n goedkoper oorgangsstuk van dieselfde Iengte vervang kan word sonder om inlaatkapasiteit in te boet, weI suksesvol aangewend kan word om kostes in die ontwerp van stOlIDwater randsteeninlate te bespaar. - Afdoende bewyse is gevind dat die "effektiewe inlaatlengte" konsep, waarvolgens 'n gedeelte van die duur inlaatgedeelte met 'n goedkoper oorgangsstuk van dieselfde Iengte vervang kan word sonder om inlaatkapasiteit in te boet, weI suksesvol aangewend kan word om kostes in die ontwerp van stOlIDwater randsteeninlate te bespaar. - Riglyne is ook ontwikkel vir die bepaling van stroomop oorgangslengtes. Die riglyne kan saam met die bestaande en die nuwe ontwerpgrafieke gebruik word by die ontwerp van stormwater nmdsteeninlate.

Full textAbstract:
Spring transition of overseeded turf has become a major challenge to turfgrass managers in the southern United States. Turf-type ryegrasses which exhibit increased mowing and heat tolerance have made the return of bermudagrass problematic, especially in common bermudagrass. Herbicides were evaluated for use as a Spring transition agent to decrease ryegrass competition/enhance bermudagrass. Treatments of TADS 14776 experimental herbicide, Manor, Kerb and Corsair were applied to overseeded common bermudagrass on may 6, 2001. Application of TADS experimental herbicide at all rates above 0.21 ounce/product increased bermuda enhancement over Kerb, Corsair and Manor, by 29 June 2001. When applied with extra fertilizer applications, the 0.21 ounce rate of TADS was greater than that of Kerb, Corsair and Manor for bermuda transition. TADS applied at the highest rate of 0.64 ounce (+) fertilizer, and TADS @ 0.42 ounce (+) GENAPOL 150 surfactant and extra plot fertilizer, were the first treatments to exhibit total necrosis of the perennial ryegrass overseed by 4 June (1 month after treatment). However, these treatments created a poorer quality turf, compared to other treatments. TADS @ 0.42 ounce (+) extra plot fertilizer ranked highest in bermudagrass plot cover, with five times as much bermudagrass present than untreated controls on 29 May. This same treatment continued with this trend, achieving 100% bermudagrass cover by 29 June (highly desirable). This treatment resulted in a brief decrease in turfgrass quality at 9 and 16 days after treatment (14 May, 21 May). With that in mind, TADS @ 0.42 ounce (+) extra plot nitrogen proved to be the best treatment that produced acceptable levels of turf quality throughout the transition, yielding the fastest re-establishment of the underlying common bermudagrass. At the close of the test on 10 July, TADS @ 0.21 ounce (+) fertilizer and TADS @ 0.42 ounce (+) fertilizer closed with 88% and 99% bermudagrass cover, and mean quality scores of 6.0 and 7.0 respectively. At the close of the test, untreated overseeded common bermudagrass yielded unacceptable turf quality, 19% bermudagrass cover, 14% living green ryegrass cover, with the remainder being dead ryegrass (straw).

La construction d'un futur collisionneur linéaire e+/e− est prévue pour obtenir des mesures précises (à l'échelle du T eV ) qui seraient complémentaires de celles obtenues du LHC. Un des défis de ce collisionneur linéaire sera de focaliser le faisceau à des tailles transverses nanométriques au point d'interaction, afin d'obtenir une importante luminosité de quelques 10^−34 cm^2 s^−1 . Les deux projets de collisionneur linéaire (ILC et CLIC) requièrent un système de distribution du faisceau partageant le même schéma de correction de chromaticité locale dans le système de focalisation finale. ATF2 à KEK (Japon), une implémentation de ce schéma mis à l'échelle en énergie, utilise le faisceau extrait d'ATF, qui est un des meilleurs anneaux d'amortissement au monde. Les objectifs d'ATF2 sont de prouver la faisabilité et la stabilité du système de focalisation finale et de définir et tester les procédures de corrections expérimentales. Les tailles nominales du faisceau au point d'interaction sont de 3µm horizontalement et 37nm verticalement. Le travail de thèse a commencé avant la mise en service et en couvre la première année à KEK. Au début, nous avons observé que les BPMs 'stripline' ne fonctionnaient pas correctement, nous avons donc examiné leurs comportements en détail. Le problème a été caractérisé puis résolu plus tard, en 2010, en changeant l'électronique. Nous avons alors développé une procédure efficace pour vérifier la modélisation de la ligne de faisceau, en comparant les mesures des matrices de transfert aux prédictions du modèle calculé en direct. Après avoir obtenu un bon accord, nous avons pu tester avec succès l'algorithme de correction de trajectoire que nous avions développé, réduisant la différence entre les mesures obtenues par les BPMs et les valeurs cibles jusqu'à 0.5mm horizontalement et 0.2mm verticalement. Nous avons aussi développé avec succès un algorithme pour reconstruire les fluctuations de la trajectoire du faisceau pour chaque paquet avec une résolution inférieure au micron. Cette reconstruction détermine aussi les fluctuations en énergie, permettant un ajustement général de la fonction de dispersion sur la longueur de la ligne de faisceau avec une précision de quelques millimètres, dominé par les erreurs systématiques provenant des matrices de transfert et des incertitudes sur les facteurs d'échelles des BPMs. Une méthode simple et robuste de réglage de la taille du faisceau à l'IP utilisant des déplacements de sextupoles a aussi été étudiée en simulation. Les performances indiquent que, en faisant quelques hypothèses sur le niveau d'erreur du faisceau, la convergence à 20% de la taille nominale devrait être possible en 8 heures avec une probabilité de 80%. Les premiers résultats expérimentaux de telles méthodes de réglages de la taille du faisceau sont actuellement en cours pour 2010 et 2011.

One of the challenges of this LC will be to focus the beam down to nm level transverse sizes at the interaction point, to obtain a high luminosity. The two LC projects (lLC and CLlC) require beam delivery systems with the same local chromaticity correction scheme in the final focus (FF). ATF2 at KEK (Japan) implements this scheme scaled down in energy, uses the beam extracted from the ATF damping ring. The ATF2 goals are to prove the feasibility and the stability of the LC FF system and to define and test the experimental correction procedures. The work in this thesis was st3lied before the commissioning and covered its first year at KEK. At the beginning, we observed that the striplines BPMs were not working properly. The problem was characterized and later solved in 20] 0 by upgrading the electronics. We then developed an efficient procedure to check the modelling of the beam line. Then, we were able to successfully test the trajectory correction algorithm which had been developed. We also successfully developed an algorithm to reconstruct pulse to pulse beam trajectory fluctuations with sub-flm precision. This reconstruction also gave a precise determination of the energy fluctuation, allowing a global fit of the dispersion function along the beam line with a precision of a few mm.

Full textAbstract:
In this thesis, I’m working from the premise that postmodernism hitherto has been associated with the left. The next line of argument is, however, that this relation is contingent and that there is no necessity in postmodernisms association with left-wing ideas and political ambitions. To challenge this assumption, I intend to demonstrate that the Alt-Right, a far-right movement, at least in some respects can be considered as postmodern. If there is indeed cause to think of the Alt-Right as postmodern, then we would have to rethink postmodernisms political inclination. I intend to operationalize this by looking at the Alt-Right’s views on the changeability of politics and the social world, and pop culture, through the lens of a set of postmodern ideas. In particular, postmodern ideas concerning language, discourse and culture, and in doing so get a grip on whether it is correct to view the Alt-Right as postmodern or not. If a connection between the Alt-Right and postmodernism indeed exists, then we would have to rethink the necessity in the left-wing nature of postmodernism.

Sporedni proizvodi dobijeni u procesu mlevenja žitarica, pšenične i ovsene mekinje, hidrotermički su tretirane u cilju dobijanja gelova, koji se, kao zamenjivači masti, mogu koristiti u formulacijama prehrambenih proizvoda. Optimizacija procesnih parametara (koncentracija mekinja, vreme homogenizacije i temperatura homogenizacije) proizvodnje gelova vršena je primenom postupka odzivne funkcije (RSM). Gelovi od pšeničnih i ovsenih mekinja, koji su pripremljeni po prethodno utvrđenim optimalnim parametrima (za pšenične mekinje: 22,0% koncentracija mekinja, vreme homogenizacije od 11,7 min i temperatura homogenizacije od 83,2°C; za ovsene mekinje: 22,0% koncentracija mekinja, vreme homogenizacije od 10,0 min i temperatura homogenizacije od 95,0°C), su, dalje, kao zamenjivači masti, bili inkorporirani u formulaciju keksa na različitim nivoima supstitucije masti (30%, 40% i 50%).Fizičke, teksturne i senzorske karakteristike keksa sa zamenjivačima masti ispitane su u poređenju sa kontrolnim (punomasnim) keksom, te je nivo zamene od 30% izabran kao najpogodniji u smislu sniženja sadržaja masti, sa jedne strane, i ostvarenja željenih karakteristika, sa druge strane.S obzirom da su proizvedeni zamenjivači masti na bazi mekinja nutritivno vredni i bogati funkcionalnim komponentama, ustanovljeno je da je dodatak ova dva funkcionalana zamenjivača masti na nivou od 30% doprineo poboljšanju nutritivnih i funkcionalnih svojstava keksa u pogledu povećanog sadržaja prehrambenih vlakana i minerala, povoljnijeg odnosa PUFA/SFA, kao i porasta sadržaja antioksidativno delotvornih komponenti.Wheat and oat brans, by-products of grain processing, were processed by hydrothermal treatments into the form of gels for partial replacement of fat in food products.Response surface methodology (RSM) approach was applied to examine the effects and to optimize process parameters (bran concentration, homogenization time and homogenization temperature).Wheat and oat bran gels prepared according to the previously determined optimal parameters (for wheat bran: 22.0% bran concentration, homogenization time of 11.7 min and homogenization temperature of 83.2 °C; for oat bran: 22.0 % bran concentration, homogenization time of 10.0 min and homogenization temperature of 95.0 °C) were further incorporated as fat substitutes into the cookie formulation at different levels of substitution (30%, 40% and 50%).The physical, texture and sensory properties of cookies with fat replacers were examined in comparison with the control (full fat) cookies, and the fat replacement level of 30% was chosen as the most suitable in terms of reducing the fat, on the one hand, and achieving the desired mentioned characteristics, on the other.Knowing that the produced fat replacers are nutritionally valuable and rich in functional components, it has been found that the addition of these two functional fat replacers at the level of 30% contributed to the improvement of the nutritional properties of cookies in terms of higher content of dietary fibers, minerals and more favourable ratio of PUFA/SFA, as well as higher content of antioxidant components.

Full textAbstract:
Le Liban se caractérise au sein de la Méditerranée orientale par sa diversité climatique, son organisation orographique (littoral/montagne/bassin) et la prépondérance des terrains carbonatés (60 % de son territoire). Ces caractéristiques font que le Liban connait sur un espace relativement réduit une grande diversité de phénomènes karstiques. Il constitue alors un espace-clé pour développer des référentiels tant pour les événements paléogéographiques qu'environnementaux qui puissent être appliquées sur le Proche-Orient. Plusieurs questionnements relatifs à la genèse des paysages et leur évolution restent encore non résolus face à la rareté des témoins morphogéniques de surface. L'endokarst constitue alors une nouvelle archive naturelle et environnementale pour pallier à ces contraintes. Ces archives se situent à la fois dans les formes des réseaux souterrains et dans les enregistrements sédimentaires (dépôts détritiques et chimiques : spéléothèmes). La recherche doctorale se concentre sur "l'apport des enseignements de l'endokarst dans la reconstitution des environnements passés et de la morphogénèse des vallées karstiques'. Les sites d'études retenues dans cette recherche sont situées dans le Mont-Liban central: i) la vallée du Nahr el-Kelb et le réseau de Jeita et, ii) la vallée d'Antelias et la grotte de Kanaan et le réseau de Kassarat-Nabay. La recherche a deux principaux objectifs: i) poser le cadre paléogéographique des principaux systèmes karstiques dépendant de la Méditerranée (systèmes de Jeita et d'Antelias) à partir de l'approche géomorphologique appliquée dans les grottes de Kanaan, de Kassarat-Nabay et de Jeita. Celle-ci met en œuvre la démarche cartographique des systèmes souterrains étudiés pour replacer les différents objets d'étude dans leur contexte spatial, morphogénique et chronologique ; et ii) appréhender les changements environnementaux de cette région liés aux variations climatiques et aux occupations humaines. L'étude sédimentaire (détritique) repose sur une analyse fine (morphoscopique, morphométrique, minéralogique, colorimétrique et magnétique) des dépôts endokarstiques.

Full textAbstract:
Grave markers reflect a wealth of information and collectively epitomize society's historic, social, and economic patterns over time. Despite an abundance of cemetery research in other parts of the country, little research has been undertaken to evaluate grave marker attributes in Florida. The purpose of this research was to determine how grave marker attributes have changed over time in north-central, central, and southeast Florida. Data were collected from ten cemeteries in five counties in Florida, representing the grave markers of over 1,100 individuals. Data collection involved visiting each cemetery, photographing markers, and cataloging grave marker attributes. Attributes analyzed included marker type, marker material, epitaphs, iconographic images, memorial photographs, footstones, and kerbs. A number of important trends were noted. Marker material exhibited the clearest example of a temporal trend, shifting over time from 73% marble to 73% granite. Marker type varied greatly from upright and flat ground markers to a variety of customized markers and vaults. Cultural differences were also noted with in-ground vaults dominating traditionally black cemeteries. There were clear differences in marker style between affluent and less affluent cemeteries, with numerous hand-cast cement markers observed in less prosperous areas. Furthermore, beginning in the early 1980's there is an increase in customized laser engraved markers. Overall, Florida's cemeteries offer a rich history of the state's mortuary practices and further research should be conducted to preserve this history.B.S.

Sporedni proizvodi industrijske prerade voća, trop borovnice i maline, postupcima sušenja i mlevenja prevedeni su u oblik pogodan za aplikaciju u prehrambene proizvode. Ovako dobijeni sastojci imaju visok sadržaj prehrambenih vlakana, esencijalnih masnih kiselina poput linolne i α-linolenske, a karakteriše ih i izbalansiran odnos PUFA/SFA. Od makronutrijenata, u najvećoj koncentraciji prisutni su K, Mg i Ca. Imajući u vidu da su glavne fitohemikalije bobičastog voća polifenolna jediinjenja, u proizvedenim funkcionalnim sastojcima određen je sadržaj ukupnih rastvorljivih polifenola, antocijana i flavonoida, kao i sastav i sadržaj odabranih polifenolnih jedinjenja primenom LC/MS-MS tehnike.Primena osušenih i samlevenih tropova kao sastojaka prehrambenih proizvoda ispitana je u formulaciji bezglutenskog keksa, sa ciljem njegovog funkcionalnog obogaćivanja. Za optimizaciju formulacije keksa korišćen je postupak odzivne površine (RSM), a formulacija u kojoj je bezglutenska smeša zamenjena sa 28,2% tropa borovnice i 1,8% tropa maline dobijena je kao optimalna, uzimajući u obzir sve zadate kriterijume. Dodatkom ova dva funkcionalana sastojka u gorenavedenom odnosu, postignuto je značajno poboljšanje nutritivnih svojstava bezglutenskog keksa, a dobijeni proizvod po kvalitetu može da parira komercijalno dostupnim funkcionalno obogaćenim keksovima, namenjenim zdravoj populaciji.Rezultati dijetetske interventne studije sprovedene na 20 zdravih, normalno uhranjenih ispitanika ženskog pola, ukazuju da se konzumiranjem kreiranog bezglutenskog keksa u količini od 32 g dnevno, postiže značajna redukcije LDL holesterola, i povećanje nivoa adiponektina u krvi, a budući da se ovaj adipocitni-sekretorni protein dovodi u vezu sa antiinflamatornim i antiaterogenim potencijalom u tretmanu metaboličkog sindroma i dijabetesa tipa 2, može se očekivati protektivno dejstvo kreiranog bezgutenskog keksa.Blueberry and raspberry pomace, by-products from fruit juice industry, were processed into the new food ingredients by drying and grinding. The obtained functional ingredients are characterized by high content of dietary fibres and essential fatty acids (linoleic and α-linolenic acid), as well as by optimal ratio of PUFA/SFA. The main macronutrients in dried and ground pomace are K, Mg and Ca. The content of total phenolic compounds, anthocyanins and flavonoids were determined, as well as composition and content of individual phenolic compounds using LC/MS-MS in order to evaluate their antioxidant potential.In the form of dried powder, blueberry and raspberry pomace were used as ingredients in formulation of gluten-free cookies. Response surface methodology (RSM) approach was applied to obtain optimal ingredients proportion. Formulation in which gluten-free flour mixture is substituted with 28.2% of the blueberry and 1.8% of the raspberry pomace was found to be optimal following the used optimization criteria. Addition of blueberry and raspberry pomace has led to a remarkable improvement in nutritional properties, and resulted in a product with similar nutritional profile with commercially available gluten containing cookies.Dietary intervention study on a group of 20 healthy, normal weight female subjects was conducted to investigate the health effect of the created gluten-free cookies. The results showed a significant reduction in levels of LDL cholesterol, and an increase in plasma concentrations of adiponectin, suggesting a potential positive effect of the created product on human health.

Full textAbstract:
Abstract In this thesis, a new type of laser diode transmitter using enhanced gain-switching suitable for use with a single photon avalanche diode (SPAD) detector was developed and tested in the pulsed time-of-flight laser range finding (lidar) application. Several laser diode versions were tested and the driving electronics were developed. The driving electronics improvements enabled a pulsing frequency of up to 1 MHz, while the maximum laser output power was about 5–40 W depending on the laser diode dimensions. The large output power is advantageous especially in conditions of strong photon noise emerging from ambient light outdoors. The length of the laser pulse matches the jitter of a typical SPAD detector providing several advantages. The new laser pulser structure enables a compact rangefinder for 50 m distance measurement outdoors in sunny conditions with sub-centimeter precision (σ-value) at a valid distance measurement rate of more than 10 kHz, for example. Single photon range finding techniques were also shown to enable a char bed level measurement of a recovery boiler containing highly attenuating and dispersing flue gas. In addition, gated single photon detector techniques were shown to provide a rejection of fluorescent photons in a Raman spectroscope leading to a greatly improved signal-to-noise ratio. Photonic effects were also studied in the case of a pulsed time-of-flight laser rangefinder utilizing a linear photodetector. It was shown that signal photon noise has an effect on the optimum detector configuration, and that pulse detection jitter can be minimized with an appropriate timing discriminatorTiivistelmä Tässä työssä kehitettiin uudentyyppinen, tehostettua "gain-switchingiä" hyödyntävä laserdiodilähetin käytettäväksi yksittäisten fotonien avalanche-ilmaisimien (SPAD) kanssa, ja sitä testattiin pulssin lentoaikaan perustuvassa laseretäisyysmittaussovelluksessa. Useita laserdiodiversioita testattiin ja ohjauselektroniikkaa kehitettiin. Ohjauselektroniikan parannukset mahdollistivat jopa 1 MHz pulssitustaajuuden, kun taas laserin maksimiteho oli noin 5–40 W riippuen laserdiodin dimensioista. Suuri lähtöteho on edullinen varsinkin vahvoissa taustafotoniolosuhteissa ulkona. Laserpulssin pituus vastaa tyypillisen SPAD-ilmaisimen jitteriä tarjoten useita etuja. Uusi laserpulssitinrakenne mahdollistaa esimerkiksi kompaktin etäisyysmittarin 50 m mittausetäisyydelle ulkona aurinkoisessa olosuhteessa mm–cm -mittaustarkkuudella (σ-arvo) yli 10 kHz mittaustahdilla. Yksittäisten fotonien lentoaikamittaustekniikan osoitettiin myös mahdollistavan soodakattilan keon korkeuden mittauksen, jossa on voimakkaasti vaimentavaa ja dispersoivaa savukaasua. Lisäksi portitetun yksittäisten fotonien ilmaisutekniikan osoitettiin hylkäävän fluoresenssin synnyttämiä fotoneita Raman-spektroskoopissa, joka johtaa selvästi parempaan signaali-kohinasuhteeseen. Fotoni-ilmiöitä tutkittiin myös lineaarista valoilmaisinta hyödyntävän pulssin kulkuaikamittaukseen perustuvan lasertutkan tapauksessa. Osoitettiin, että signaalin fotonikohina vaikuttaa optimaaliseen ilmaisinkonfiguraatioon, ja että pulssin ilmaisujitteri voidaan minimoida sopivalla ajoitusdiskriminaattorilla

Full textAbstract:
Cette recherche est née du désir de combler le manque de visibilité de la poésie indienne contemporaine en France. Elle se présente comme un travail comparatif entre la poésie indienne de langue anglaise, à travers l’étude des oeuvres d’Arun Kolatkar (1932-2004) et de Keki Daruwalla (né en 1937), et la poésie indienne de langue hindi, à travers celle de Gajanan Madhav Muktibodh (1917-1964) et de Kedarnath Singh (né en 1934). Ces oeuvres illustrent le passage d’une poésie protestataire, ouvertement transitive, à une poésie qui s’écarte de son assujettissement à des idées et de la pression d’événements extérieurs. C’est par une « poétique de la relation », selon laquelle toute identité s’étend dans un rapport à l’altérité et à la diversité, que ces quatre poètes répondent à la fragmentation du champ politique, culturel et social, perçu en termes d’antagonismes et de ruptures au milieu du vingtième siècle en Inde. Cette recherche étudie la relation de la poésie au contexte d’énonciation dans laquelle elle s’inscrit. Celle-ci passe par une forme de dissidence vis-à-vis de l’autorité énonciative que la langue anglaise et la langue hindi représentent, vis-à-vis de l’autorité institutionnelle et vis-à-vis de certains discours idéologiques. Leurs textes sont intertextuels et dialogiques. Ils s’inspirent de l’héritage immédiat de la modernité et de tout un « sous-continent » oral, folklorique, syncrétique et hétérodoxe. Ils déjouent toute tentative d’appropriation exclusive de la langue, du sens, de la vérité, d’une identité ou d’un passé. Cette dissidence poétique est l’instrument d’une conversion du regard, de l’altération et de la pluralisation du réel. En restaurant la poétique, la poésie indienne contemporaine la restaure aussi comme politiqueThis research endeavours to make up for the lack of visibility and of academic attention given to contemporary Indian poetry in France. It is a comparative study between Indian poetry in English, focusing on the works of Arun Kolatkar (1932-2004) and Keki Daruwalla (born in 1937) and Indian poetry in Hindi, focusing on the works of Gagajan Madhav Muktibodh (1917-1964) and Kedarnath Singh (born in 1934). Their works illustrate the evolution of Indian poetry from a transitive protestpoetry, to a more indirect dissidence, which keeps away from ideology and from the pressure of outside events. These four poets respond to the dislocation and the fragmentation of the Indian cultural, political and social field in the middle of the twentieth century by giving shape to a « poetics of relation », to borrow a term from Edouard Glissant, which expresses the idea that without the other there is no language for the self. They claim a hybrid heritage, that of the immediate impact of modernity, but also that of a plural and often heterodox « non-literate sub-continent ». They challenge the purity and the closure of the monolithic text, by asserting overlapping, reflexive, dialogic identities and by creating an intertextual, multilingual fabric for their poetry. These plural belongings and plural identities subvert any kind of exclusive understanding of language, of meaning, of the sacred, of the past or of identity. The emphasis is on the conversion of the act of seeing, on revealing rather than on loudly demonstrating, and this poetic conversion is fundamentally political

U nastavku istraživanja ispitivana je antioksidantna aktivnosti etanolih ekstrakata primenom direktnih, ESR “spin trap“ spektroskopskih metoda određivanja “skevindžer“ aktivnosti na superoksid anjon i hidroksil radikale i indirektnih, spektrofotometrijskih testova za određivanje skevindžer“ aktivnosti na DPPH˙ radikale, redoks potencijala i helatacione aktivnosti, kao i antioksidantne aktivnosti u sistemu β-karoten-linolna kiselina. Osim navedenog, deo istraživanja je posvećen ispitivanju termičke stabilnosti ekstrakata navedenih biljaka i komercijalnog preparata Vitalplant® radi sticanja uvida u mogućnost njihove primene u pekarskim proizvodima. U poslednjoj fazi rada, izvršeno je određivanje sposobnosti pulvisa i etanolnog ekstrakta komercijalnog preparata Vitalplant® da inhibiraju oksidaciju lipida u keksu, primenom spektrofotometrijskih testova “skevindžer“ aktivnosti na DPPH˙ radikale i MDA testa. Ispitane biljne sirovine, kao i komercijalni preparat Vitalplant® su bogat izvor jedinjenja iz klase biljnih fenola. Sve ispitane biljne droge poseduju antioksidantnu aktivnost, koja se značajno ne menja usled termičkog tretmana. Dodatak biljne mešavine Vitalplant® , upravo proporcionalno njenom sadržaju, dovodi do povećanja antioksidantne aktivnosti keksa i smanjenja stepena lipidne peroksidacije. In this paper, quantitative determination and identification of plant phenolics and flavonoids of ethanolic extracts obtained from parsley fruit (Petroselini fructus), buckthorn bark (Frangulae cortex), mint leaves (Mentha piperitae folium), caraway fruit (Carvi fructus), birch leaves (Betulae folium), as well as from commercial preparation Vitalplant® ((Frangulae cortex(35 %), Mentha piperitae folium (20%), Carvi fructus(20 %), Petroselini fructus (25 %)) was performed. In addition, antioxidant activity of ethanolic extracts was tested, by applying direct, ESR “spin trap“ spectroscopic methods for the determination of scavenging activity on superoxide anion and hydroxyl radicals, and indirect, spectrophotometric methods for the determination of DPPH˙ radical scavenging activity, reducing power, chelating activity and antioxidant activity in β-carotene-linoleic acid model system. Moreover, thermal stability of the ethanolic extracts was tested in order to get insight into possible application of the extracts in bakery products. Finally, the ability of the commercial preparation Vitalplant®, in the form of powder and extract, to inhibit oxidative changes of cookies was tested by applying spectrophotometric DPPH radical scavenging and MDA tests.According to obtained results, investigated plant samples, including commercial preparation Vitalplant®, are rich source of plant phenolics. Investigated plant drugs possess antioxidant activity, which is not significantly changed after the thermal treatment. Cookie supplementation with commercial preparation Vitalplant® results in better oxidative stability of lipids and enhanced antioxidant activity of the cookies.

Full textAbstract:
Submitted in partial fulfilment for the Master of Technology Degree: Chemistry, Durban Institute of Technology, 2003.In urban environments motor vehicles are by far the largest source oflead. In areas subjected to heavy and slow moving vehicular traffic, the amount of lead exhausted may be quite high. Since exhaust fumes settle on kerb-sides, soil samples from these areas may not only give a good measure of the accumulation of lead but also eliminate the need to risk expensive sampling equipment in collecting air samples. In order to determine the levels of lead and other toxic metals such as chromium, cadmium, nickel, copper and aluminium, soil samples were collected from kerb-sides and road islands around the City of Durban and along the national road N3 in the vicinity of Shongweni. City, peri-urban and rural roads were selected for sampling. In a preliminary study, kerb-side dust from one of the streets with very heavy vehicular traffic was collected. It is also a street where many vendors have food stalls. The horizontal distribution of metals as a function of distance from the kerb was determined by analyzing samples which were collected at various distances from the edge of a road. The determination of vertical distribution of metals in the soil was also performed. Samples for this work were collected by digging 0 to 2 cm, 10 to 15 cm and 20 to 25 cm deep at various points along the National Highway (N3). 111 Some sub-samples were leached at pHs found in soils using a Hazardous Waste Filtration System while other sub-samples from the same gross sample were aciddigested in a Microwave Digester. The analyses were done using ICP-ABS, AAS and GF-AAS. As expected the values for lead were the highest for urban sites and lowest for rural ones and values from leaching experiments were lower than those for digested samples from the same site. Taken over all sites, the values for lead ranged from 0.02 to 298 ppm for leached samples and from 25 to 1900 ppm for digested samples.

BACKGROUND: Descending kerbs during locomotion involves the regulation of appropriate foot placement before the kerb-edge and foot clearance over it. It also involves the modulation of gait output to ensure the body-mass is safely and smoothly lowered to the new level. Previous research has shown that vision is used in such adaptive gait tasks for feedforward planning, with vision from the lower visual field (lvf) used for online updating. The present study determined when lvf information is used to control/update locomotion when stepping from a kerb. METHODOLOGY/PRINCIPAL FINDINGS: 12 young adults stepped down a kerb during ongoing gait. Force sensitive resistors (attached to participants' feet) interfaced with an high-speed PDLC 'smart glass' sheet, allowed the lvf to be unpredictably occluded at either heel-contact of the penultimate or final step before the kerb-edge up to contact with the lower level. Analysis focussed on determining changes in foot placement distance before the kerb-edge, clearance over it, and in kinematic measures of the step down. Lvf occlusion from the instant of final step contact had no significant effect on any dependant variable (p>0.09). Occlusion of the lvf from the instant of penultimate step contact had a significant effect on foot clearance and on several kinematic measures, with findings consistent with participants becoming uncertain regarding relative horizontal location of the kerb-edge. CONCLUSION/SIGNIFICANCE: These findings suggest concurrent feedback of the lower limb, kerb-edge, and/or floor area immediately in front/below the kerb is not used when stepping from a kerb during ongoing gait. Instead heel-clearance and pre-landing-kinematic parameters are determined/planned using lvf information acquired in the penultimate step during the approach to the kerb-edge, with information related to foot placement before the kerb-edge being the most salient.

Globalization has affected all ethnic groups in Africa. Cameroonian Grassfield is still among those which have been preserved diverse customs and rituals. In the past, the Fondom Kedjom Keku - today, village Big Babanki became the focus of this anthropological work. The aim is to understand and describe the current state of the traditional religion of the inhabitants of this village. For comparison with the original form of each religious phenomena serves a number of publications, researches and interviews with witnesses. This work is based on my field research, participatory observation, interviews and questionnaires. My attention is fixed on a belief in Kedjom gods, spirits, souls of ancestors and contemporary celebration of death, magic and witchcraft, supernatural power of amulets, spiritual power of twins and secret societies. Considering the frequency of allegations of witchcraft, this theme is also elaborated in general view with regard to the Kedjom Keku people and the whole Grassfield. Since the connection with the supernatural world is not the only domain of wizards and witches, but this power can be...

The Extreme Forward Calorimeter (EFC) is successfully running in KEK for BELLE and she is made by the Taiwan BELLE Group. We had a beam test for the prototype EFC at KEK-PS p2 beam line by using beams with energy for 1 to 3 GeV and the prototype EFC was 1/8 of her full scale one. Due to space limitations, the BGO crystals have only 12 radiation lengths. The measured energy resolution is about 7-10% and linearity about 1%. I also do the physics simulation studies in the B+ * w p+ mode. In my study, 1973 signal events are accepted in 100,00 events, and 75 background events are in 1.92* 106 events. After calculating in the B+ * w p+ mode assumptive branching ratio is 1.0*10-5 and the continue background is more 2.8 times than the signal, the S/N is 1.86%.

In my study, 1973 signal events are accepted in 100,00 generated events, and 75 background events are kept in 1.92* 106 continuum events. Assuming the branching ratio of B+ -> w pi+ is 1* 105, we obtain the S/N is ~ 1.86%.

Eine Suche nach dem Zerfall B → π τ ν wird vorgestellt. Die Suche wird auf dem vollständigen Belle Datensatz durchgeführt, der 772E6 B anti-B Paare beinhaltet, die auf der Y(4s) Resonanz mit Belle Detektor am asymmetrischen e+e- KEKB Beschleuniger gesammelt wurden. Das τ Lepton wird in den Zerfallskanälen τ → e ν ν, τ → μ ν ν, τ → π ν und τ → ρ ν rekonstruiert. Eines der beiden B Mesonen, das Btag, wird mittels eines auf NeuroBayes beruhenden Algorithmus vollständig in einem hadronischen Zerfallskanal rekonstruiert. Der Rest des Kollisionsereignisses beinhaltet genau zwei geladene Spuren im Falle eines Signalzerfalls. Die weitere Trennung zwischen Signal und Untergrund wird mithilfe von Boosted Decision Trees durchgeführt. Ein Fit wird in der Verteilung der Extra Energie im elektromagnetischen Kalorimeter ECL, welche definiert ist als alle Energie die weder vom Btag noch von der rekonstruierten Signalseite stammt, durchgeführt. Kein signifikantes Signal wird beobachtet und ein oberes Limit von Br( B → π τ ν ) < 2.5E-4 basierend auf einem Vertrauensintervall von 90% wird bestimmt. Das Ergebnis ist in guter Übereinstimmung mit der Vorhersage des Standard Modells.

Full textAbstract:
Le fonctionnement du jugement moral demeure controversé dans la littérature. Certaines théories affirment que, par définition, le jugement moral dépend des émotions (théorie des marqueurs somatiques de Damasio), tandis que d'autres mettent l'accent sur l'importance de la cognition, comme le fait la théorie de Kohlberg. Cette théorie du jugement moral est née dans les années 1970, alors que plusieurs fonctions humaines étaient encore définies par le postulat du constructivisme psychologique. Ce postulat met l'accent sur les fonctions cognitives et les stades pour expliquer le développement des facultés humaines. Aujourd'hui, la théorie de Kohlberg est sévèrement critiquée par ceux qui adoptent une position sentimentaliste, mettant l'accent sur les émotions pour expliquer le jugement moral. Pourtant, la théorie de Kohlberg a subi plusieurs modifications dont les critiques ne tiennent pas compte. Le but de cette thèse était de montrer comment la théorie de Kohlberg est à jour et permet d'étudier le jugement moral avec les émotions. Afin d'atteindre cet objectif, deux études ont été menées. La première de ces études fut une recherche théorique de type argumentatif. Elle a permis de remettre à jour la théorie de Kohlberg en s'appuyant sur les travaux de deux chercheurs, Krebs et Rest, qui se sont attaqués 1) à la conception constructiviste du cadre de la théorie (stades, cognition) et 2) à l'absence de plusieurs variables importantes dans la définition du jugement moral (personnalité, émotions). Krebs a utilisé le concept de stratégies plutôt que de stades. Selon l'auteur, ces stratégies sont des structures intuitives qui peuvent se retrouver chez les animaux, les enfants et les adultes et dont l'expression dépend du contexte écologique ou social. Rest a parlé de schèmes, structures intuitives aussi présentes à la naissance, dont l'importance pourrait varier en fonction de plusieurs composantes (notamment psychologiques). Finalement, cette étude conclut en présentant une théorie néo-kohlbergienne du jugement moral. Il est aujourd'hui possible d'utiliser cette théorie en parlant d'émotions et de fonctions cognitives. La deuxième étude visait à mesurer l'impact des émotions sur les schèmes moraux de la théorie néo-kohlbergienne et à mesurer les fonctions cognitives impliquées traditionnellement dans le jugement moral (intelligence, fonctions exécutives et théorie de l'esprit). Quatre-vingt-quatre jeunes adultes normaux (40 hommes et 44 femmes) ont écouté deux versions de dilemmes (neutre et avec ton dramatique). Les résultats ont montré que les pourcentages des schèmes préconventionnels ont diminué dans la condition avec ton dramatique. Par ailleurs, les pourcentages des schèmes postconventionnels ont diminué chez les hommes, mais ont augmenté chez les femmes dans la condition dramatique. Comme fonction cognitive, la théorie de l'esprit était corrélée positivement avec les schèmes postconventionnels. En outre, plus les sujets étaient flexibles, plus ils obtenaient des pourcentages des schèmes conventionnels dans la condition dramatique. Ces résultats confirment le rôle des émotions et des fonctions cognitives pour expliquer le jugement moral et montrent des différences de ce jugement entre les sexes. En conclusion, cette thèse a montré qu'il y a la place pour les émotions dans la théorie néo-kohlbergienne, pour mieux comprendre le jugement moral. Cette thèse confirme que les émotions permettent de diminuer le pourcentage des schèmes d'intérêts personnels (préconventionnels), mais n'augmentent pas nécessairement les pourcentages des schèmes prosociaux (postconventionnels) chez tout le monde. Ce pourcentage diminue chez les hommes tandis qu'il augmente chez les femmes et les fonctions cognitives classiques contribuent partiellement à expliquer le jugement moral.

A new measurement of the neutron electric dipole moment (nEDM) is being
developed at TRIUMF, where a high density source of ultra cold neutrons
(UCN) is currently under construction. A fast, high-efficiency UCN detector
is needed for the experiment, and a 6-Li doped glass scintillation detector is
being explored for this purpose. In this work, simulations and test measurements
were carried out to optimize the light guide design for the new UCN
detector. Acrylic and air-core light guides, the latter with two different reflecting
surfaces, were considered. Three prototype light guides were constructed
and tested, and results were compared with simulations. The best solution
was found to be an acrylic guide, wrapped with mylar foil. For a guide 12
cm in length as required by the experimental layout, a lower limit of approximately
25 photoelectrons per neutron capture was established for the proposed
geometry and photomultiplier configuration.May 2016
