This study aims to identify, through the application of webometric indicators, which Post-Graduate Courses in Engineering recommended by the Coordination of Improvement of Higher Personnel Education (CAPES) in Brazil stand out in the web space, in relation to the communication process and dissemination of scientific information in the academic environment. For this, we analyzed the structures content of the sites, the use, through the conduct of investigations and searches, the quality of information available, as well as the structure of existent hypertexts in the sites of this universe of search. The tools and methodologies adopted for this study are: search engines (Google, Yahoo), Mapper software (Xenu Link Sleuth) and analysis software and visualization of networks (and Ucinet6 NetDraw). Webometric indicators are also used, such as size of the web sites, visibility, web impact factor, brightness and density of the network. These instruments provide a brief analysis and evaluation for this webometric study. Therefore, from the incursion of the literature used, it appears that there are many advantages of using this type of metric study in the so called Information Society. The obtained results could identify which postgraduate courses in engineering has a better availability of their information on the Web, as well to define which of these courses stands out in relation to the use of their information, which has been outstanding in respect to its impact factor and which offers a greater number of links that serve as a source of information for its users, contributing, in its turn, with the navigability of the same network. In summary, it is asserted that the webometric study presents promising results, which are able to achieve the proposed objectives, as well as identify the factors that contribute significantly to the good visualization of these sites in the network, thus helping the spread of information and scientific communication through the use of the Web.

This Master of Science Thesis deals with a BSC modeling for higher education institution focusing on private institution in the Brazilian context. It‟s accomplished a literature review in order to understand the BSC and its application to for profit and non for profit organizations and as a main result it is proposed a BSC conceptual model with a new perspective (Government) and a change in the hierarchy of the main BSC perspective equaling financial to customer/society. Taking the national higher education assessment system of Education Ministry indicators a model is deployed and the relations between the indicators are measured with the Pearson correlation coefficient. As a result a model emerges with sound relations of indicators but a improvement in the financial indicators is needed

O objetivo deste estudo foi avaliar indicadores da eficiência produtiva de vacas Nelore selecionadas para peso pós-desmama, enfocados nas relações peso bezerro e peso da vaca, nos rebanhos controle (NeC), não-selecionados para peso pós-desmama, seleção (NeS) e tradicional (NeT). As análises envolveram 3929 e 3906 pesos dos bezerros aos 120 (P120) e 210 (P210) dias de idade, respectivamente. Os pesos das vacas àquelas idades também foram considerados, obtendo-se 3824 (PV120) e 3777 (PV210) registros, respectivamente, para 120 e 210 dias. A análise incluiu 183, 375 e 554 vacas dos rebanhos NeC, NeS e NeT, respectivamente. Para as análises utilizou-se o procedimento GLM/SAS, em modelos que incluíram os efeitos fixos de rebanho, ano e mês de nascimento, sexo do bezerro, idade da vaca ao parto e as interações rebanho x ano de nascimento e ano x mês de nascimento. Todos os efeitos foram significativos. Os resultados mostraram respostas correlacionadas positivas na seleção para peso pós-desmama nos pesos dos bezerros e, em menor magnitude, no peso das vacas. As relações peso bezerro e peso da vaca apresentaram valores médios ajustados de 249,0±2,1; 253,7±1,6; e 255,8±1,2 g/kg para R120 e 362,9±2,8; 368,5±2,1; e 374,6±1,7 para NeC, NeS e NeT em R210, respectivamente, indicando que, nas duas idades, os rebanhos NeS e NeT produziram mais quilogramas de bezerro por quilogramas de vaca, quando comparados ao NeC.

The Expansion Plan of the Federal Network of Vocational Education foresees the construction of 860 new units of instruction until 2020, representing a strong growth against the 140 existing units prior to its disclosure by Federal Government of Brazil, in 2005. The Federal Institutes of Education, Science and Technology have been performing the expansion while experiencing the shortcomings and challenges of units still in development, created in previous phases of the Plan. The quality of the services of these institutions has been evaluated by the control bodies, which require the submission of performance indicators in annual management reports of institutions under their jurisdiction. In this context of expansion process, particularly, is desirable to identify possible changes in quality standards. Thus, this research was motivated by the following problem: there was difference in the performance of the Federal Institutes of Education, Science and Technology after the inauguration of the first units of phase II of the Expansion Plan of the Federal Network of Vocational Education? This is an exploratory-descriptive, ex-post-facto, quantitative approach research, which aims to contribute to the knowledge of the impact of the expansion of the Federal Network. The data were collected from 12 indicators presented in management reports of 38 Federal Institutes through years 2007 to 2011 to evaluate the performances using descriptive statistical techniques. The indicators were analyzed in both consolidated and open manners by the following perspectives: country region, growth of instruction units and institutions origin. Was also performed a multivariate analysis of clusters in order to identify excellence groups of Institutes. The results showed differences in the expansion plan s development among Brazilian regions, both in terms of infrastructure and academic indicators, with better results in the Midwest and South, and that there are differentiated profiles of institutes as its origin, where the best quality indicators occur in those originated by integration of different educational institutions. Still, were identified two excellence groups, with emphasis on academic management, human resources and expansion

O objetivo deste trabalho foi comparar os indicadores internos, fibra em detergente neutro e fibra em detergente ácido indigestíveis, obtidos após 144h de incubação in vitro e in situ (FDNiv; FDNis; FDAiv; FDAis) com o indicador externo, o óxido crômico (Cr2O3), para estimativas da produção fecal, do fluxo duodenal de matéria seca e matéria orgânica em novilhos mestiços (HxZ) confinados. Foram utilizadas dietas à base de silagens de milho, de raspa e de casca de mandioca, e também de cana-de-açúcar ensilada com polpa cítrica peletizada. Os novilhos foram castrados e canulados no rúmen e no duodeno. O período experimental teve 11 dias de adaptação às dietas e 8 dias de coleta. O delineamento experimental foi o quadrado latino (4x4), com quatro tratamentos, num arranjo em parcela subdividida, sendo as dietas estudadas nas parcelas, e os indicadores nas subparcelas. Os resultados obtidos em percentagem do peso vivo para a estimativa da produção fecal, utilizando-se os diferentes indicadores, mostraram que a FDAiv (0,88 %), a FDAis (0,85 %) e o Cr2O3 (0,99 %), embora com diferenças significativas, podem ser utilizados pelos resultados biologicamente consistentes. Para estimar o fluxo duodenal de matéria seca e matéria orgânica, foram utilizados os valores de produção fecal obtidos com a FDAiv. Os indicadores internos não apresentaram diferenças entre si para o fluxo duodenal de matéria seca, com média de 3,29 kg/dia, porém o óxido crômico superestimou o fluxo (4,95 kg/dia). Para o fluxo duodenal de matéria orgânica não houve diferença entre os indicadores com média de 2,73 kg/dia.

Performance measurement in highly competitive markets is a necessary measure for those who aim the top positions. The business performance measurement approach have reached relevant results in the literature, however, a different approach has recently appeared that broadened the perception of competition, where companies do not seek the competition among companies only, but also among supply chains. Brazilian Wind energy supply chain is living a structuring and expanding moment, with the major global players in the industry making investments in the country. This research aims to answer which are the key performance indicators that must be considered by the Brazilian wind energy sector companies, which are part in a broad perspective of supply chain competition. The research was executed in two steps: exploratory (literature review and a field research in the companies) and later a survey was conducted with the Brazilian Wind energy companies workers with the purpose to validate the performance indicators found in the exploratory step. The survey evaluated 40 performance indicators distributed among five major activities: Project prospection, building/execution, operation and maintenance, logistics and transverse processes, which summarize the performance of the entire supply chain, pointing the sinergy and the competitive level of the supply chain. The selected performance indicators reflect the high relevance of the costs dimension in the Brazilian energy companies performance, acting as a key performance indicator, is also indicates the limited performance management integration throughout the Brazilian wind energy supply chain

This paper presents the validation of the Performance Indicator System for Projects under Construction - SIDECC. The goal was to develop a system of performance indicators from the macroergonômica approach, considering criteria of usefulness, practicality and applicability and the concept of continuous improvement in the construction industry. The validation process SIDECC consisted of three distinct models. Modeling I corresponded to the theoretical development and validation of a system of indicators. Modeling II concerns the development and validation of multi- indicator system. For this modeling, we used the Mother of Use and Importance and Multivariate Analysis. Modeling III corresponded to the validation situated, which consisted of a case study of a work of construction of buildings, which were applied and analyzed the results of modeling II. This work resulted in the development of an applied and tested for the construction of an integrated system of performance indicators methodology, involving aspects of production, quality, environmental, health and safety. It is inferred that the SIDECC can be applied, in full or in part, the construction companies as a whole, as well as in other economic sectors

Avaliaram-se os indicadores fibra detergente ácido indigestível (FDAi) e óxido crômico (Cr2O3) na estimativa das digestililidades parciais e total das frações nutritivas da dieta. Foram utilizados quatro tourinhos Santa Gertrudes canulados no rúmen e no duodeno, distribuídos em delineamento quadrado latino 4 × 4 (animais ´ período) para estimativa da digestibilidade de quatro dietas compostas de feno de capim-marandu e concentrados, ajustadas para proporcionar ganho de peso corporal diário de 0,5 e 1 kg/animal e potencial de fermentação microbiana de 9,5 e 11 g de PB microbiana/MJ em fermentável. Os suplementos foram formulados com mistura mineral, milho, soja e farelos de soja e algodão. Não houve interação significativa dietas ´ indicadores. À exceção dos coeficientes de digestibilidade intestinal da MS e da FDN, todos os outros coeficientes de digestibilidade (MS, PB e CT) diferiram significativamente entre os indicadores avaliados. Quando utilizado o indicador FDAi, foram registrados maiores valores de digestibilidade ruminal e total e menores coeficientes de digestibilidade intestinal. A FDAi possibilitou melhor estimativa dos coeficientes de digestibilidade dos nutrientes das dietas, quando compostas na sua maior parte de volumosos (57 a 70% da MS).

The fly of the syrphid Microdon tigrinus is a specific social parasite of leaf-cutting ant, Acromyrmex coronatus. Six colonies of Acromyrmex coronatus were collected in plastic containers, which there was a layer of 1 cm of plaster, with the purpose of maintaining the humidity of fungus culture. Larvae of social parasite were separate for the establishment of instars number, through morphometric study. The data were measured of 165 larvae, using spiracle (length (Ls), width (Ws) and distance between spiracle (Ds)). After that, the morphometric data obtained for the larvae were submitted to cluster analysis by Wong's hybrid method, which produces the adequate number of groups through pseudo F-statistics and pseudo t-squared statistics. The three morphometric variables studied permitted grouping of larvae into the following three distinct groups: cluster 1 [long dash] consisting of 55 larvae (Ls=0.177[plus or minus]0.026, Ws=0.163[plus or minus]0.030, Ds=0.052[plus or minus]0.008 mm); cluster 2 - consisting of 20 larvae (Ls=0.631[plus or minus]0.065, Ws=0.630[plus or minus]0.049, Ds=0.065[plus or minus]0.018 mm); cluster 3 - consisting of 90 larvae (Ls=1.294[plus or minus]0.062, Ws=1.308[plus or minus]0.069, Ds=0.140[plus or minus]0.018 mm). of the all couples, only 1 obtained success in the mating, and the female, after 24 hours, began the oviposition. The female layed 76 eggs in a period of 6 days, after that, her death. The larvae emerged in the seventh day (incubation period [plus or minus] 7 days). From 76 eggs, 54 were viable, with a viability of 71.05%. This study contributes to the knowledge of Microdon tigrinus biology of, a social parasite poorly studied in Brazil.

A broca do pedúnculo floral do coqueiro, Homalinotus coriaceus (Gyllenhal), é uma praga limitante à produção de coco no Brasil, provocando a queda das flores e dos frutos imaturos. Sua biologia é pouco conhecida o que tem dificultado a seu manejo adequado no campo. Dessa forma, foi realizado o estudo da biologia desse inseto no Laboratório de Entomologia da Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Tabuleiros Costeiros - CPATC, em Aracaju, SE, à temperatura de 25 ± 2°C, umidade relativa de 70% e fotofase de 12h. Para alimentação e oviposição dos adultos coletados no campo foram utilizados toletes de cana-de-açúcar como substrato, nos quais as fêmeas colocaram ovos individualizados, cujo período de incubação variou de seis a 14 dias. As larvas foram criadas no mesocarpo de coco, desenvolvendo-se em 144 dias em média, passando por cinco a sete ínstares. O período pupal médio foi de 31 dias. A longevidade do adulto variou de 303 a 695 dias para fêmeas e de 246 a 635 dias para machos, sendo o ciclo de ovo a adulto de 181,9 dias para fêmeas e 188,5 para machos. Foram observadas diferenças morfológicas nas pupas e nos adultos, que podem ser utilizadas para separação dos sexos. Ao contrário dos machos, as fêmeas apresentam, na fase de pupa, duas estruturas arredondadas e elevadas situadas na face ventral e final do abdome e, na fase adulta, o penúltimo tergito abdominal projeta-se sobre o último.

Visando conhecer a relação parasito hospedeiro de M. enterolobii em plantas com resistência a nematoides das galhas, estudos comparativos da biologia de M. enterolobii e M. javanica em tomateiros com o gene Mi foram conduzidos. O experimento foi conduzido em esquema fatorial 2x2, composto de dois porta-enxertos de tomateiro ('Magnet' e 'Helper M') e duas espécies de nematoides das galhas (M. enterolobii e M. javanica) com cinco repetições. As plantas foram inoculadas com 500 juvenis infectantes (J2) de M. enterolobii ou M. javanica. As raízes foram coletadas aos 3, 10, 17, 24 e 31 dias após a inoculação, coloridas com fucsina ácida, e dissecadas sob microscópio estereoscópico para a localização e contagem dos diferentes estádios de desenvolvimento dos nematoides. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de probabilidade. Os resultados obtidos mostraram que, embora ambas as espécies tenham sido capazes de penetrar as raízes dos porta-enxertos de tomateiro, somente M. enterolobii conseguiu desenvolver-se normalmente, com as fêmeas maduras realizando suas posturas, a partir de 24 dias após a inoculação.
