O gênero Prochilodus é amplamente distribuído pela América do Sul, incluindo várias espécies que apresenta certo grau de endemismo nas diferentes bacias. Essas espécies alimentam-se basicamente de detritos orgânicos, organismos do benton, e alimentações artificiais. O objetivo deste estudo foi testar três densidades de estocagem (0,5, 0,75, e 1 larva/litro) e dietas contendo dois níveis diferentes de proteína bruta (35 e 40% PB) nos parâmetros do crescimento e na taxa da sobrevivência do curimbatá, Prochilodus scrofa. As larvas foram estocadas em aquários experimentais de 100 litros, mantidos com volume de 60 litros, com o fluxo de água contínuo, proveniente de poço semi-artesiano. A maior média foi proporcionada pela ração com 40% de PB (1,66g ± 0,21). As diferenças foram significativas para os efeitos dos teores de PB sobre o ganho de peso e densidades de estocagem, na sobrevivência das larvas. Para o ganho de peso, as melhores médias foram obtidas com nível de 40% de PB (2,50g ± 0,40) e para a sobrevivência, as melhores taxas foram 94,45% ± 19,32 e 78,87% ± 19,32 nas densidades de 0,5 e 0,75 larvas/litro, respectivamente.

During ethanol production, starch is the primary nutrient fermented and the remaining byproducts are excellent sources of fiber and protein. In addition, inclusion of byproducts in finishing diets may reduce the incidence of acidosis. As a result, roughage level and quality could potentially be reduced in finishing diets containing byproducts. Three experiments were conducted to examine the effects of roughage and wet corn gluten feed (WCGF) in finishing cattle diets containing corn distillers grains plus solubles. Cattle fed finishing diets containing wet distillers grains plus solubles (WDGS) with no roughage had decreased DMI and ADG compared to cattle fed roughage. Within roughage level, ADG was similar for cattle fed alfalfa hay, corn silage or corn stalks when included on an equal NDF basis. Apparent total tract digestibility of OM, NDF, and CP linearly decreased and ruminal pH variables increased linearly due to increasing roughage levels. Roughage sources can be exchanged on an equal NDF basis in beef finishing diets containing 30% WDGS (DM basis). In finishing diets containing modified distillers grains plus solubles (MDGS), DMI linearly increased due to increasing roughage levels but ADG responded quadratically and was lowest for cattle fed diets without roughage. There was also a quadratic response for DMI and ADG due to WCGF inclusion level. Gain:feed decreased linearly with increasing roughage and WCGF inclusion levels. Feeding 15% WCGF resulted in similar cattle performance and carcass traits to cattle fed no WCGF in diets containing 30% MDGS, but cattle fed diets with 60% total byproduct inclusion made up of 30% WCGF and 30% MDGS had reduced performance (DM basis). Additionally, reducing corn silage inclusion level to 7.5% resulted in similar finishing cattle performance and carcass traits to cattle fed 15% corn silage in diets containing 30% MDGS with or without inclusion of WCGF. Elimination of roughage in diets containing either WDGS or MDGS resulted in negative impacts on finishing cattle performance, ruminal metabolism, and carcass traits.

In this thesis I examine the issues of postcolonial Algerian identity expressed in literature, and the difficulty of defining an Algerian identity independent of French influence. I analyze and contextualize three novels (Le Polygone etoile by Kateb Yacine,L'Amour, la fantasia by Assia Djebar, and Le Village de l'allemand ou le journal des freres Schiller) representative of their respective periods. I explore the evolution of expressions of identity through post-liberation Algeria. The years immediately following decolonization are marked by the effort to return to aprecolonial blank slate, an effort that Yacine cautions against. The 1980s and 1990s are most concerned with re-inserting Algeria into the Western historical discourse, and the most recent literature moves beyond decolonization to discuss the current Islamistchallenge and immigration. Among the pertinent issues are language, oral vs. written traditions, the often blatant absence of Algerians and women from the accounts in the French colonial archives, and, of course, the Self/Other binary. I have found that theserepresentative authors and texts use asynchronic time, fragmented narrative, re-written history, and expressions of violence in an attempt to cope with the colonial period and decolonization. I show that these authors provide a commentary on those who have triedto erase their French side, but with little success. Ultimately, though in different ways, each author writes that Algerians much accept their French past and move beyond it,rather than fighting their collective history.

Workshops are an important part of the IFPA annual meeting as they allow for discussion of specialized topics. At IFPA meeting 2011 there were twelve themed workshops, four of which are summarized in this report. These workshops related to both basic science and clinical research into placental growth and nutrient sensing and were divided into 1) placenta: predicting future health; 2) roles of lipids in the growth and development of feto-placental unit; 3) placental nutrient sensing; 4) placental research to solve clinical problems: a translational approach.

In December 2013, the European Union (EU) enacted the reformed Common Agricultural Policy (CAP) for 2014–2020, allocating almost 40% of the EU's budget and influencing management of half of its terrestrial area. Many EU politicians are announcing the new CAP as “greener,” but the new environmental prescriptions are so diluted that they are unlikely to benefit biodiversity. Individual Member States (MSs), however, can still use flexibility granted by the new CAP to design national plans to protect farmland habitats and species and to ensure long-term provision of ecosystem services
