Determinação da composição mineral de subprodutos agroindustriais utilizados na alimentação animal, pela técnica de ativação neutrônica

O presente trabalho teve como objetivo analisar alguns subprodutos agroindustriais utilizados na alimentação animal e identificar os principais minerais presentes. Amostras de farelos de algodão, arroz, canola, soja e trigo; farinhas de peixe, carne e penas + vísceras; cascas de algodão, arroz, laranja; bagaços de tomate e de laranja foram coletadas em diferentes locais de produção. O método analítico empregado foi a análise por ativação com nêutrons seguida de espectrometria gama. Os níveis de minerais encontrados em todas as amostras, inclusive aqueles considerados tóxicos, tais como As, Cd e Hg, não excederam os limites máximos permitidos em dietas para animais domésticos. Os valores obtidos foram comparados com os comumente encontrados em forragens.

PRODUÇÃO ANIMAL EM PASTAGEM DE MILHETO SOB DIFERENTES NÍVEIS DE NITROGÊNIO

O experimento foi conduzido em área da Universidade Federal de Santa Maria, RS, com o objetivo de verificar os efeitos de três níveis de adubação nitrogenada (0, 150 e 300 kg/ha de N) em pastagem de milheto (Pennisetum americanum (L.) Leeke) cv. Comum, sobre a produção animal. Foram utilizados novilhos de corte e avaliados o desempenho por animal, o número de animais.dia/ha e o ganho de peso vivo por área. O sistema de pastejo adotado foi o contínuo, com ajustes de carga para manter uma pressão de pastejo de 10%, caracterizando um resíduo médio de 3.168 kg de matéria seca/ha. As variáveis dependentes mostraram relação linear positiva com os níveis de adubação nitrogenada, o que denota o alto potencial do milheto.

Factors associated with healthcare professionals' intent to stay in hospital: a comparison across five occupational categories.

OBJECTIVE: To identify factors associated with intent to stay in hospital among five different categories of healthcare professionals using an adapted version of the conceptual model of intent to stay (CMIS). DESIGN: A cross-sectional survey targeting Lausanne University Hospital employees performed in the fall of 2011. Multigroup structural equation modeling was used to test the adapted CMIS model among professional groups. Measures Satisfaction, self-fulfillment, workload, working conditions, burnout, overall job satisfaction, institutional identification and intent to stay. PARTICIPANTS: Surveys of 3364 respondents: 494 physicians, 1228 nurses, 509 laboratory technicians, 935 administrative staff and 198 psycho-social workers. RESULTS: For all professional categories, self-fulfillment increased intent to stay (all β > 0.14, P < 0.05). Burnout decreased intent to stay by weakening job satisfaction (β < -0.23 and β > 0.22, P < 0.05). Some factors were associated with specific professional categories: workload was associated with nurses' intent to stay (β = -0.15), and physicians' institutional identification mitigated the effect of burnout on intent to stay (β = -0.15 and β = 0.19). CONCLUSION: Respondents' intent to stay in a position depended both on global and profession-specific factors. The identification of these factors may help in mapping interventions and retention plans at both a hospital level and professional groups' level.

Planning sleep-related animal and translational research

With the aim of improving human health, scientists have been using an approach referred to as translational research, in which they aim to convey their laboratory discoveries into clinical applications to help prevent and cure disease. Such discoveries often arise from cellular, molecular, and physiological studies that progress to the clinical level. Most of the translational work is done using animal models that share common genes, molecular pathways, or phenotypes with humans. In this article, we discuss how translational work is carried out in various animal models and illustrate its relevance for human sleep research and sleep-related disorders.

Is our heart a well-designed pump? The heart along animal evolution.

A carrier system for gases and nutrients became mandatory when primitive animals grew larger and developed different organs. The first circulatory systems are peristaltic tubes pushing slowly the haemolymph into an open vascular tree without capillaries (worms). Arthropods developed contractile bulges on the abdominal aorta assisted by accessory hearts for wings or legs and by abdominal respiratory motions. Two-chamber heart (atrium and ventricle) appeared among mollusks. Vertebrates have a multi-chamber heart and a closed circulation with capillaries. Their heart has two chambers in fishes, three chambers (two atria and one ventricle) in amphibians and reptiles, and four chambers in birds and mammals. The ventricle of reptiles is partially divided in two cavities by an interventricular septum, leaving only a communication of variable size leading to a variable shunt. Blood pressure increases progressively from 15 mmHg (worms) to 170/70 mmHg (birds) according to the increase in metabolic rate. When systemic pressure exceeds 50 mmHg, a lower pressure system appears for the circulation through gills or lungs in order to improve gas exchange. A four-chamber heart allows a complete separation of systemic and pulmonary circuits. This review describes the circulatory pumping systems used in the different classes of animals, their advantages and failures, and the way they have been modified with evolution.

Anàlisi de les teràpies assistides amb cans en infants amb el trastorn de l'espectre autista

El que es trobarà a continuació és tot el procés de recerca del Treball Final de Grau, on el tema clau s’engloba amb tot el que és el món de la Teràpia Assistida amb Gossos aplicades dintre l’àmbit de les persones amb diferents tipus de discapacitat. No obstant, aquest és un ampli col·lectiu i per tant, s’ha centrat en el context del Trastorn de l’Espectre Autista. És a dir, la finalitat que es busca amb aquesta investigació és saber si les Teràpies Assistides amb Gossos aporten beneficis a infants amb aquest trastorn. La recerca ha estat realitzada amb unes metodologies concretes. Per un costat, s’ha dut a terme un estudi de cas amb observació descriptiva d’un infant amb Trastorn de l’Espectre Autista. Aquí s’ha fet un seguiment d’unes sessions de teràpia concretes amb l’infant autista, el gos i el terapeuta. Així doncs, a partir d’aquest s’ha analitzat, mitjançant unes categories específiques, els beneficis que aporta aquest animal, com a eina terapèutica, a l’Autisme. Encara que, per contrastar aquest, s’ha tingut en compte la opinió des de la vessant familiar i la professional, arribant a una informació més detallada a partir de l’entrevista.
