2. Produção de embriões em ovinos Morada Nova e Somalis Brasileira
ABSTRACT Superovulatory response and embryo yield in 19 Morada Nova and 20 Somalis Brasileira ewes was analyzed. All animals were synchronized with the insertion of an intravaginal device (CIDR(r)) on Day 0, replaced by a new device on Day 7, which remained in place until Day 14 and superovulated with 133mg of porcine FSH (pFSH) in decreasing doses at 12h in

3. Real time PCR and importance of housekeepings genes for normalization and quantification of mRNA expression in different tissues
The aim of this review was to evaluate the importance of the real-time PCR (qRT-PCR) as a technique for mRNA expression analysis in different tissues. Real-time PCR is widely used for quantification of mRNA levels and is a fundamental tool for basic research, molecular medicine and biotechnology.Genes of references are expressed in a wide variety of tissues

4. Problemas de corte com sobras aproveitáveis e eliminação de simetrias / Cutting stock problems with usable leftover and symmetry breaking
In this work we study two variations of the packing problem where identical rectangular items must be packed into a polyhedron. One of the variations consists in finding the largest amount of rectangular items that can fit in a polyhedron. The other one consists in finding a minimal area polyhedron of a certain type that packs a set of rectangular identical

5. Modulação do transporte de prótons em osteoclastos: efeitos da acidose e do fluxo de fluido extracelular. / Modulation of proton transport in osteoclasts. Effects of acidosis and extracellular fluid flow.
Metabolic acidosis can cause a loss of bone mineral and the mechanic stimulation can cause adaptative bone remodeling. The bone resorption characteristic of these bone changes aforementioned depends on the extracellular acidification by osteoclastmediated proton secretion. The H+ secretion by vacuolar H+-ATPase together with Clsecretion through a Cl-/H+ exch

6. Os precos de bovinos no Pantanal Mato-Grossense.
The Pantanal of Mato Grosso is a plain of c. 139.000 km2, on the Brazilian central plateau, situated between 16o and 22o of latitude South and 55o and 58o longitude West, where one of the largest breeding center of beef cattle is developed. Animal husbandry is explored with minimal technical inputs within a climate of alternating water excess or sthortage. T

7. Árvores de Steiner: Teoria, Geração Numérica e Aplicações / Steiner trees: Theory, Numerical Generation and Applications
Given a set of points in the plane, which we call terminals, one proves that they are always connected by a minimal graph called Steiner tree. The terminals may represent main connection route points, circuit elements or network computer servers. That is, the problem is to optimize traffic among the terminals whenever this is represented by a tree of shortes

8. Estudio mineralógico, microtermométrico y aspectos estructurales de la mineralización de topacio imperial de Antônio Pereira, Distrito de Ouro Preto (Minas Gerais) - Brasil
The occurrences of imperial topaz in the Antonio Pereira mine, Ouro Preto, Minas Gerais, are associated with the metamorphic carbonate rocks of the Minas Supergroup. The crystals have densities varying from 3.46 to 3.58. The parameters of the unitary cells obtained were: 4.658 to 4.663Å (a o), 8.823 to 8.832Å (b o), 8.382 to 8.389Å (c o), and 344.65 to 34

9. Ecological wood anatomy and cambial activity of Roupala rhombifolia (Proteaceae) in Serra do Cipó (MG) / Anatomia ecológica do lenho e atividade cambial de Roupala rhombifolia (Proteaceae) na Serra do Cipó (MG)
The intensity of environmental variations is smaller on tropical than temperate regions. Therefore, tropical species were considered for years as evergrowing. In addition, environmental variations can exist in small and big scales and species should respond differently depending on each environmental stimulus. By these reasons, the aim of the study was to an

10. Morphological characterization of mitochondrial alterations in hepatic steatosis of cause not defined in childhood group / Caracterização morfologicas das alterações mitocondriasis na esteatose hepatica de causa não determinada em grupo pediatrico
Hepatic steatosis unrelated to alcoholism may occur separately or be part of fatty liver disease (NAFLD). It encompasses a wide spectrum of morphologic alterations, ranging from steatosis to a more severe stage accompanied by fibrosis and cirrhosis. The aim of our study was to assess and characterize childhood steatosis of not defined cause carrying out morp

11. Dez peças para quinteto de sopros de György Ligeti: a gradação como uma ferramenta para a construção do discurso musical / Dez peças para quinteto de sopros de György Ligeti: a gradação como uma ferramenta para a construção do discurso musical
The main goal of this dissertation is to describe the gradual processes used by György Ligeti in its work Ten pieces for wind quintet (1968). Through this description we try to put in evidence the gradual processes as an important tool in the construction of the Ten pieces language. The analysis of the Ten pieces considers different parameters or aspects of

12. A limit-method for solving period problems on minimal surfaces / Metodo limite para solução de problemas de periodos em superficies minimas
In this work we present the study and construction of minimal surfaces through an exclusive method. In 1762, Lagrange introduced the Minimal Surfaces Diferential Equation through the Calculus of Variations, and today the theory of such surfaces builds up an active and broad research area. We obtain new families of minimal surfaces based upon the Reverse Cons
