1. Caracterização da curva de crescimento de fêmeas Crioulas Lageanas criadas em condições naturais
Morphometry and ultrasound of carcasses were used to estimate the growth curve of Criola Lageana cows, raised under natural conditions. A total of 111 cows, raised under extensively production system in Central Plateau of Santa Catarina, were evaluated. Morphometrics and ultrasound measurements were related with the age of the animals using the targeted univ

2. Growth curve of locally adapted pantaneiro cows raised under natural conditions
The objective of this study was to use morphometric and ultrasound evaluations to estimate the growth curve of the Pantaneiro cattle breed, raised in its natural habitat, aiming at the re-insertion of this breed in production systems. One hundred and three females, aging from months to 11 years, and raised on native pastures, were evaluated. The animals belo

3. ReaÃÃes biocatalÃticas usando cÃlulas Ãntegras de Lens culinaris (Lentilha). / REACTIONS USING WHOLE CELL BIOCATALYTIC LENS CULINARIS (LENTIL)
This paper describes the use of seeds of lentil (Lens culinaris) as intact plant system in biocatalytic reactions of reduction and hydrolysis. Initially, some plant sources were evaluated for their action in the biocatalytic reduction of aromatic ketone acetophenone. The plants that showed positive results in the reduction reaction underwent determination of

4. COMPETIÃÃO TRIBUTÃRIA VERTICAL NO BRASIL: EVIDÃNCIAS EMPÃRICAS PARA ICMS X IPI NO PERÃODO DE 1995 A 2009 / VERTICAL TAX COMPETITION IN BRAZIL: EVIDENCE EMPIRICAL TO X ICMS IPI THE PERIOD 1995 TO 2009
The main objective of this study is quantify the impact caused by changes in federal tax on the tax policy of the states, considering the presence of horizontal tax competition between states. In federal systems, where various levels of government operate simultaneously in the same tax regime, setting tax rates on the same basis of taxation, there may be the

5. Association of polymorphisms in the leptin and thyroglobulin genes with meat quality and carcass traits in beef cattle
The objective of the present study was to estimate the allelic and genotypic frequencies of the polymorphisms E2FB (AY138588.1: c.305C> T), located in the leptin gene (LEP), and TG5 (X05380.1:g.-422C>T), located in the thyroglobulin gene (TG), and evaluate the association of these polymorphisms in crossbred cattle of seven distinct genetic groups with the fo

6. AÃÃo broncodilatadora e anti-inflamatÃria do 1,8-cineol em modelo experimental de asma em cobaias / Bronchodilator and anti-inflammatory action of 1,8-cineole in experimental model of asthma in guinea pigs
Dentre as doenÃas obstrutivas das vias aÃreas, a asma envolve processos broncoconstritores e inflamatÃrios, ambos fisiologicamente reversÃveis. O uso terapÃutico do 1,8-cineol (eucaliptol) nessa disfunÃÃo vem sendo estudado nos Ãltimos anos. Nesse estudo, objetivou-se avaliar o efeito do eucaliptol na contratilidade da musculatura lisa das vias aÃre

7. Modelagem hidro-mecÃnica de estruturas de concreto afetada pela reaÃÃo Ãlcali-agregado
Some structures of concrete in direct contact with the humidity, that have been executed with the use of potentially reactive aggregate and alkali text cement high, are affected to the alkali-aggregate development of reactions (RAA). The development of these reactions leads to the formation of a gel that in the water presence expands exerting pressure in the

8. Accounting information systems: modeling and intelligent agents application / Sistemas de informação contábeis: modelagem e aplicação de agentes inteligentes
A contabilidade é ciência destinada ao tratamento da informação de eventos econômicos que ocorrem dentro das organizações. Diversas técnicas de registro e tratamento de dados foram desenvolvidas ao longo do tempo para gerar informações relevantes nas tomadas de decisões. Nesse sentido, a contabilidade tem sua origem no método das partidas dobrada

9. SimulaÃÃo numÃrica do comportamento mecÃnico de elementos de concreto armado afetados pela reaÃÃo Ãlcali-agregado / Numerical simulation of the mechanical behaviour of reinforced concrete members affected by alcaliaggregate reaction
The subject of this work is the numerical simulation of the swelling due to alkaliaggregate reaction in reinforced concrete members. The inert chemically nature of the aggregate of cement Portland concrete was early questioned by Stanton (1940), nevertheless, just awaked Civil Engineering community interest, in 1980âs decade, because its damage in concrete

10. DesinfecÃÃo de Ãgua contaminada com Escherichia Coli: desenvolvimento de fotorreator e estudo cinÃtico
A Ãgua tem influÃncia direta sobre a saÃde, a qualidade de vida e o desenvolvimento do ser humano. A maioria das enfermidades (80%) que ocorrem em paÃses em desenvolvimento à ocasionada por contaminaÃÃo microbiana da Ãgua. Em conseqÃÃncia, a desinfecÃÃo de Ãgua de consumo e residuÃria à necessÃria. O uso da RadiaÃÃo UV-C ( = 253,70 nm) como

11. Estudo da reaÃÃo de desidro-aromatizaÃÃo nÃo-oxidativa do metano em reator de leito fixo diferencial com catalisador Ru-Mo
Natural gas reserves are considered an important source of energy and raw material for the chemical and petrochemical industries. Therefore, the catalytic conversion of methane, which is the main component of natural gas, has been shown of great interest. Among the different catalytic processes, the de-hydro-aromatization of methane (DAM) under no-oxidative

12. Estudo da ReaÃÃo de Desidro-aromatizaÃÃo nÃo oxidativa do Metano em Reator de Leito Fixo Diferencial com catalisador Ru- Mo/HZSM-5
Chemical routes suitable for the activation of methane to produce valuable products are limited and its achievement consists in a challenge to the chemistry of the natural gas conversion. Although remarkable progresses have been achieved on the methane dehydroaromatization (MDA) reaction, low conversion caused by severe thermodynamic limitations, coke format
