Diplomityön tavoitteena on tutkia eri vaihtoehtojen kannattavuutta pienvesivoimalan uusinnassa. Sähkönhinnan muodostus ja tulokseen vaikuttavat tekijät käsitellään kokonaisuuksinaan. Työssä tehdään kustannuslaskenta valmistajien tarjouksien perusteella ja suoritetaan esittely eri tarjouksista. Valmisteluosassa tutustutaan mitoitusarvoihin ja jos niitä ei ole miten ne selvitetään. Mittauksen kautta saadut arvot käsitellään ja sovelletaan siten, että valmistajat pystyvät käyttämään niitä. Lisäksi tutustutaan turbiinin laskentaan ja mitoitetaan Kaplan-turbiini työssä käytettyyn pienvesivoimalaan.

Ce mémoire en recherche-création explore l’hybridation identitaire et le désir d’échapper aux attentes normatives. Dans le récit Ce ne sont que des corps, deux étrangers attendent le train en se racontant, en alternance, les événements qui ont marqué les derniers mois de leur vie. Emmanuel, âgé de vingt-cinq ans, s’éprend de Michelle, une femme de tête quinquagénaire rencontrée dans un bar. Cette femme rêve de réaliser certains fantasmes et Emmanuel accepte de se plier au jeu jusqu’à ce que les choses s’enveniment. Quant à Alex, jeune femme dans la vingtaine, elle quitte son village natal pour étudier à Montréal et succombe au charme de Gabriel, un aspirant musicien pour qui elle est prête à tout abandonner. Chacun des personnages de ce roman brouille les identités sexuées et sexuelles. Pour ce qui est de l’essai, il explore la manière dont Nelly Kaplan manipule le sexe et le gender de ses protagonistes pour postuler une « poétique de l’androgynie » dans certaines nouvelles du recueil Le réservoir des sens. L’essai mobilise les ressources des études consacrées à l’ironie, à la poétique surréaliste, au gender ainsi qu’à l’intertextualité pour mettre en évidence la façon dont l’auteure brouille les identités sexuées et sexuelles.

In most studies on beef cattle longevity, only the cows reaching a given number of calvings by a specific age are considered in the analyses. With the aim of evaluating all cows with productive life in herds, taking into consideration the different forms of management on each farm, it was proposed to measure cow longevity from age at last calving (ALC), that is, the most recent calving registered in the files. The objective was to characterize this trait in order to study the longevity of Nellore cattle, using the Kaplan-Meier estimators and the Cox model. The covariables and class effects considered in the models were age at first calving (AFC), year and season of birth of the cow and farm. The variable studied (ALC) was classified as presenting complete information (uncensored = 1) or incomplete information (censored = 0), using the criterion of the difference between the date of each cow's last calving and the date of the latest calving at each farm. If this difference was >36 months, the cow was considered to have failed. If not, this cow was censored, thus indicating that future calving remained possible for this cow. The records of 11 791 animals from 22 farms within the Nellore Breed Genetic Improvement Program ('Nellore Brazil') were used. In the estimation process using the Kaplan-Meier model, the variable of AFC was classified into three age groups. In individual analyses, the log-rank test and the Wilcoxon test in the Kaplan-Meier model showed that all covariables and class effects had significant effects (P < 0.05) on ALC. In the analysis considering all covariables and class effects, using the Wald test in the Cox model, only the season of birth of the cow was not significant for ALC (P > 0.05). This analysis indicated that each month added to AFC diminished the risk of the cow's failure in the herd by 2%. Nonetheless, this does not imply that animals with younger AFC had less profitability. Cows with greater numbers of calvings were more precocious than those with fewer calvings. Copyright © The Animal Consortium 2012.

The assessment of executive functions is an area of study that has seen considerable development in recent years. Despite much research examining the validity of various measures of executive functions from both a direct and indirect format, little evidence exists in the extant literature evaluating the correspondence between these types of measures. The current study examined the extent of correspondence, comprising concurrent validity, between the Delis-Kaplan Executive Function System (D-KEFS) and the Behavior Rating Inventory of Executive Function ¿ Self-Report Version (BRIEF-SR). Participants included 30 undergraduate and high school students 18 years of age. Results indicated mixed evidence of concurrent validity between the two measures of executive functions. The findings obtained suggest both expected significant, negative correlation as well as lack of expected correlation between the measures. Suggestions for future research in the assessment of executive functions are discussed.
