1. Improved finite element of a transversely cracked straight beam with an additional degree of freedom
Abstract A new finite element with an additional degree of freedom at the crack location is derived for static bending analysis of a transversely cracked uniform slender beam. In the simplified computational model, which is based on Euler-Bernoulli's theory of small displacements, the crack is represented by a linear rotational spring connecting two elastic

2. Maximal Information Coefficient and Support Vector Regression Based Nonlinear Feature Selection and QSAR Modeling on Toxicity of Alcohol Compounds to Tadpoles of Rana temporaria
Efficient evaluation of biotoxicity of organics is of vital significance to resource utilization and environmental protection. In this study, toxicity of 110 alcohol compounds to tadpoles of Rana temporaria is adopted as the dependent variable and 1388 physiochemical parameters (features) calculated by PCLIENT are used for representing each compound. A featu

3. Determination of Moxidectin in Serum by Liquid Chromatography-Tandem Mass Spectrometry and Its Application in Pharmacokinetic Study in Lambs
The widespread use of moxidectin (MOX), a parasiticide used in the sheep breeding, has induced the parasite resistance in Brazilian farms. As a consequence, the farmers often increase the dose and frequency of drug utilization, and disregards safety of meat or milk. In order to establish adequate therapeutic treatment it is necessary to know the pharmacokine

4. Artificial neural network for prediction of the area under the disease progress curve of tomato late blight
ABSTRACT: Artificial neural networks (ANN) are computational models inspired by the neural systems of living beings capable of learning from examples and using them to solve problems such as non-linear prediction, and pattern recognition, in addition to several other applications. In this study, ANN were used to predict the value of the area under the diseas

5. Intraspecific variation in alkaline phosphatase activity in Phaeodactylum tricornutum (Bacillariophyceae, Bohlin)
ABSTRACT To describe potential intraspecific variation in phosphorus incorporation in two strains of Phaeodactylum tricornutum (Bohlin), Ub3 and Ub7, alkaline phosphatase (AP) activity was evaluated via enzyme-labeled fluorescence assay. Analysis using the probe ELF-97(r) provides individual evaluation, and therefore can determine the nutritional status of i

6. In-vitro screening of Kalahari browse species for rumen methane mitigation
The nutritional value of browse foliage from the Thorny Kalahari Dune Bush veld of South Africa is not characterized. Most of this browse species is rich in tannin, but still palatable, and is consumed by ruminants during the dry season, as well as having a role to play in mitigating enteric methane emission from ruminants. In this study, the rumen methane m

7. Evaluation of preventative and control measures for congenital syphilis in State of Mato Grosso
Introduction Congenital syphilis is an important health problem in Brazil. This study assessed measures aimed at the prevention and control of syphilis in the State of Mato Grosso and its capital, Cuiabá. Methods A descriptive study cross-sectional and of time trends assessing the congenital syphilis was performed in Cuiabá and Mato Grosso between 2001

8. Nutritional Balance of broilers fed diets containing two calcium levels and supplemented with different phytase levels
The objective of this study was to evaluate the effect of diets containing different calcium and phytase levels on the nutritional balance of broilers.A total of 108 male AG Ross 308 broilers were used in each of the replicates phases used in the study: starter (1-21 days), grower (29-35 days) and finisher (36-42 days). A completely randomized experimental d

9. NÃveis de isoleucina digestÃvel para suÃnos machos castrados dos 15 aos 30 kg / Levels of digestible isoleucine for barrows from 15 to 30 kg.
Aiming to determine the digestible isoleucine requirement for barrows from 15 to 30 kg, two experiments were conducted, being one of digestibility and another of performance. Ten crossbreed barrows with average initial weight of 15.00 Â 0.27 kg were used to determine the ileal digestibility coefficient of amino acids from basal diet. The animals were housed

10. O acesso e a utilização dos serviços de saúde materno-infantis no município de Juiz de Fora - MG
Health inequalities come to being in many different ways in the health-disease process, be it in the form of access or the utilization of health services. Although many studies undertaken in Brazil have highlighted the existence of inequities in the utilization of health services, there are limitations in the interpretation of such approach. This study analy

11. Efficiency of metabolizable energy utilization for maintenance and gain and evaluation of Small Ruminant Nutrition System model in Santa Ines sheep
This study was carried out to estimate efficiencies of the utilization of metabolizable energy for maintenance (k m) and weight gain (k g) and to evaluate the Small Ruminant Nutrition System (SRNS) model in predicting dry matter intake and average daily gain of growing Santa Ines sheep. Twenty-four non-castrated Santa Ines sheep, at 50 days of age and with a

12. Utilization of a novel Ag(III)-luminol chemiluminescence system for determination of d-penicillamine in human urine samples
Um novo sistema de quimioluminescência (CL), sensível, (reação [Ag(HIO6)2]5--luminol), acoplado com injeção em fluxo, é introduzido para determinação de d-penicilamina. O sistema é baseado no efeito do aumento da reação de quimioluminescência por penicilamina em meio alcalino. Sob condições ótimas, a intensidade de CL é proporcional às conc
