According to current legislation, is part of the Target of Special Education, students with high abilities/giftedness (HA/G). However, it appears that there are few studies on efficiency and effectiveness of diverse pedagogical practice for students with these characteristics. With increasing globalization, are multiplied opportunities for transnational education programs and educational services, particularly through the Internet, increasing the need for information services and accreditation of institutions and educational programs. This study aims to: a) develop a website containing information on high abilities/giftedness; b) evaluate the design of teachers on applicability of the site; c) analyze the contributions posted on the site. Therefore, it was available to the participants of this research produced site. Consisted on the site, among other information, those relating to HA/G indicators. Was sent a questionnaire via the Internet, with nine closed questions and two open, to 2000 teachers, registered in the database Improvement Course in Educational Practices Inclusive conducted by UNESP, under the coordination of Prof. Dr. Vera Lucia Messias Fialho Capellini. Data were considering frequency responses. For the treatment we used the Google Docs. As result Program Observed how teachers are lacking this subject deserves further Top depth. Concerning the site he was Considered by the participants as a support tool to the teacher, Which helps to identify and recognition of Individuals with HA/G and contributes to information, training and practical pedagogical way. This, is expected to Contribute to the dissemination of this issue in society as well as the Possibility of Minimizing the myths about this population, since such myths exist due to the lack of information

Lipids have important biological functions, suchas membrane constituents, hormone precursors, and are efficient energy reserves, due to thers high caloric content. In fish, but not in mammals, lipid storage patterns are quite diverse. The aim of this study was to determine lipid distribution in somatic and reproductive tissues of matrinxã, Brycon cephalus, both male and female, highlighting somatic indices related to lipid dynamics. From Oct 98 to Jan 99, a total of 174 fish (8-12 each month) were sampled. After fish anesthesia, heparinized blood was collected for plasma triacylglycerol determination. Fish were individually weighed and measured, and liver, gonads and visceral fat were collected and weighed for HSI (hepatosomatic index), GSI (gonad somatic index) and MFI (mesenteric fat index) calculation. The highest values of total lipids were found in red muscle (about 18%), liver and gonads (about 16.5%). The white muscle had a lower concentration (2.5%). Analyses of variance of HSI and MFI showed fluctuations along the experimental period with lowest concentrations in the periods of highest temperatures. Matrinxã store lipids in several body tissues, including mesenteric fat, liver, muscles and gonads.

This work was carried out to evaluate the functional response of Cryptolaemus montrouzieri Mulsant, 1850 (Coleoptera: Coccinellidae) fed with Planococcus citri Risso, 1813 (Hemiptera: Pseudococcidae) reared on a pumpkin hybrid (Cucurbita maxima x Cucurbita moscata) (Cucurbitaceae), seedlings of Rangpur lime (Citrus limonia) Rutaceae) and potato (Solanum tuberosum) (Solanaceae) at two temperatures. The predation rate of C. montrouzieri was measured using Petri dishes of 15 cm diameter with 1, 2, 4, 8, 16 and 24 adults of P. Citri. One third instar larva, one fourfh instar and one newly emerged adult (without differentiation of sex) of C. montrouzieri were added to each plate. The study was conducted in climatic chambers at temperatures of 25 and 30 degrees C and photophase of 12 hours. The predation rate was evaluated after 24 hours of prey exposition to the predator, by counting the number of preys trapped in the different treatments and control. The statistical design was completely randomized with four treatments x 6 subplots with 7 repetitions, the two temperatures. The values obtained were subjected to analysis of variance, to relate the number of scales preyed by larvae and adults of C. montrouzieri set up in different substrates. The amount of prey consumed by larvae and adults of the predator increased with increasing the prey density until it reaches a plateau, characterizing functional response type II. In general, the number of scales preyed by larvae and adults of C. montrouzieri was higher on potato and under temperature of 30 degrees C.

Neste trabalho, foram determinados experimentalmente o calor específico, a condutividade térmica, difusividade térmica e densidade de suco de lulo na faixa de conteúdo de água entre 0,55 e 0,90 (p/p em base úmida) e em temperaturas entre 4 e 78,6 °C. A condutividade térmica e o calor específico foram obtidos utilizando-se o mesmo equipamento - uma célula constituída de dois cilindros concêntricos - operando em estado estacionário e não estacionário, respectivamente. A difusividade térmica foi obtida através do método de Dickerson e a densidade determinada por picnometria. Tanto a temperatura como o conteúdo de água apresentaram grande influência nos dados experimentais das propriedades termofísicas do suco de lulo. Os resultados obtidos foram utilizados na obtenção de modelos matemáticos para predizer estas propriedades em função da concentração e temperatura.

A Murraya paniculata, é conhecida popularmente como murta-de-cheiro ou falsamurta, pertence à família Rutaceae e é uma espécie nativa da Índia que foi introduzida no Brasil. Essa espécie é utilizada na arborização de ruas e em jardins das cidades graças à copa densa e sua resistência a condições adversas. Pode ser utilizada também para formação de cerca vivas e, sua madeira branca tem alta durabilidade podendo ser utilizada em marcenarias. Na Ásia, esta espécie é considerada medicinal e as folhas e raízes são utilizadas para o tratamento de problemas intestinais, de reumatismo e tosse. Do ponto de vista químico, esta espécie acumula principalmente cumarinas e flavonóides, além de derivados do ácido cinâmico e alcalóides. No presente trabalho propomos determinar as temperaturas cardeais para a germinação de sementes de Murraya paniculata, além disso, analisamos a influência do teor de água na germinação para determinar se as sementes são recalcitrantes ou ortodoxas, e a influencia do potencial hídrico induzido por polietilenoglicol (PEG 6000). O aprofundamento dos estudos dessa espécie se faz importante por conta desta ser hospedeira alternativa do psilídeo Diaphorina citri, transmissor do ―greening‖ dos citros, doença que diminuiu a produção de citros nos últimos anos
