In Brazil, smoking incidence varies between 9.5% and 21.2% and it is more common among men. In college students incidence can reach 14% depending on the region, which is quite disturbing. Joining college is a crucial period for the commencement or maintenance of smoking. The Knowledge among college students about tobacco use is critical to devise strategies for intervention in this population. The objectives were to establish the occurrence of smoking and risk factors, nicotine dependence in college students and college goers. We interviewed students, teachers and administrative personnel from the Philosophy and Science School at UNESP at Marilia, from both sexes, regardless their age, which visited the First Week Against Tobacco event. The sociodemographic data, smoking status, time as a smoker, cigarettes smoked, date when they started smoking, history of smoking in the family, friends or associates were questioned. We also assessed the degree of motivation to quit smoking and the degree of nicotine dependence. Data were presented using descriptive statistics. Comparisons between categorical variables were made using the chi-square test (p <0.05). A total of 432 people, 180 men and 252 women, average aged 22.6 ± 6.9 years were researched. From the volunteers studied, 267 (61.8) had tried cigarettes and 171 of them (64%) reported that they were offered by friends. As a whole, 79 (18.3%) of these people were smokers, 52 (65.8%) reported intending to quit smoking and in 37 of them (46.8%), the degree of nicotine dependence was very low. Of all the smokers, 63 had smokers in the family and all of them had friends who smoked. 28.9% of all men were smokers and 10.7%of all women. The occurrence of smoking was 18.3% and the risk factor associated to smoking habit is related to friendship and family, and very low nicotine dependence.

O interesse por esta temática de trabalho surgiu a partir de um estudo realizado em minha iniciação científica, que tem por título “Ação, Câmera, Luz: Entre imagens e olhares – experiência de infâncias e montagens” desenvolvido no Departamento de Educação do Instituto de Biociências, localizado na Universidade Estadual Paulista – UNESP/Rio Claro. Como o próprio título sugere, ela tem por principal objetivo inverter a lógica da conhecida frase: “Luz, Câmera, Ação”. Este trabalho, ao inverter a ordem dos fatores, busca ver se ao deixarmos a ação das crianças livre, o que se produziria seria algo mais verdadeiro, mais significativo, de fato. O que a ausência de intencionalidade geraria aos produtores de imagens. A partir de então, comecei a imaginar outro tipo de produção de imagens, não mais com câmeras fotográficas e filmadoras, mas de próprio punho. Portanto, este trabalho tem por objetivo analisar as crianças, e suas realidades através do que elas mesmas nos dizem e nos mostram em seu dia a dia por meio de seus desenhos. Os desenhos utilizados foram retirados de uma instituição de ensino não formal da cidade de Rio Claro, e entendidos como documentos. A pesquisa traz também um aporte teórico com as concepções sobre desenho infantil de alguns teóricos, como Lowenfel, Greig, La Pastina, Vigotski entre outros

The Companhia Energetica de Sao Paulo - CESP owns six hydroelectric dams in the state of São Paulo. The dams, both in its construction and in operation, cause some environmental impacts, most of them negatives, for example, the flooding in regions before not flooded, deviation of the river’s course, among others, bringing harm to flora and fauna of these environments. As a way to compensating these damages, the CESP has acquired a region that was influenced by Sérgio Motta Hydroelectric Plant Engineer, or Porto Primavera, and turned it into Reserva Particular do Patrimônio Natural Foz do Rio Aguapeí. By law it fits in a Conservation Unit, and thus should be contemplate for a management plan, ie, a multidisciplinary technical document which allows, simply, the practice of actions within and around in a sustainably way. This work aimed at developing a land cover map of the reserve for this plan can be made and executed more efficiently. Initially, the project included field visits and meetings with members of the CESP to be specified classes contained on the map. Later, we ran different types of classifications of multispectral images (TM / Landsat 5)... (Complete abstract click electronic access below)

Man can transform the nature according to their needs through technique which enables agriculture, cattle raising, constructions of buildings for housing, transport routes, etc. This action has brought significant transformations to the environment, and relief is one of the most changed elements, mainly at urban areas, which concentrates most of the Brazilian population. In these areas geomorphologic systems have undergone alterations in their flow of matter and energy by the action of man. Thus, it is possible o understand the action of man as geomorphologic action, nowadays, the tecnógeno, since the human action can interfere qualitatively and quantitatively in the input and output of these systems. The anthropic geomorphology has contributed to the analyses of the effects due to the urbanization at the form and at the geomorphologic process in the urban watersheds, indicating the transformations at the shape of the relief and the alterations due to the acceleration of the flow of matter and energy. From these questions, this study had the main diagnose the anthropogenic changes of the relief at the basin of Corrego do Jardim São João, Araras (SP), comparing two scenes, 1997 and 2006, through geomorphological mapping evolutionary in the area. The geomorphological feature altered at the basin are directly linked to the use of soil, mainly at the urban use, which caused effects in the relief at the studied area, making possible to define periods of the urban evolution and impacts caused by the urbanization. Among the changes it was found the decrease of the topographic breaks and at the riverbed channels, as the increase of the accumulation of the plain and riverbed terrace. The elaboration of a letter of the legal restrictions of the basin make possible to evaluate some of the environmental urban problems that occur, which are due to the occupation of the relief in the areas of permanent preservation that brings significant impacts to...

O Herpesvírus associado ao sarcoma de Kaposi (KSHV), ou Herpesvírus Humano tipo 8 (HHV-8), é o agente etiológico do sarcoma de Kaposi (SK), uma neoplasia maligna vascular. O ciclo biológico do KSHV apresenta duas fases, denominadas ciclo latente e ciclo lítico (ou produtivo). O ciclo latente é marcado pela expressão de um número reduzido de genes virais, com destaque para LANA e vFLIP. No ciclo lítico ocorre a replicação do genoma viral e a produção de novas partículas virais infecciosas; dentre seus principais produtos destacam-se as proteínas Rta, vGPCR e K1. LANA, vFLIP, vGPCR e K1 apresentam propriedades oncogênicas relatadas na literatura, enquanto Rta têm papel importante na regulação da transição entre os ciclos lítico e latente do KSHV. O KSHV é requerido para o desenvolvimento do SK. No entanto, a infecção pelo vírus não é suficiente para o desenvolvimento da doença. Por outro lado, sabe-se que o HIV é um co-fator importante, que favorece o desenvolvimento dessa neoplasia. Sugere-se que a proteína tat do HIV-1 amplifica a infectividade do KSHV, hiper-regulando a expressão de diferentes genes herpesvirais e colaborando para o crescimento e sobrevivência de células endoteliais que compõem as lesões do SK. A fim de contribuir para um melhor entendimento dos efeitos da proteína tat do HIV-1 em células infectadas pelo KSHV, o presente trabalho descreveu eventuais alterações na expressão dos genes codificadores de vFLIP, LANA, vGPCR, Rta e K1 em células endoteliais de veia umbilical humana imortalizada pela telomerase e infectada pelo KSHV a longo prazo (TIVE-LTCs) expostas à proteína tat do HIV-1 produzida por células linfóides T (CLTs) em co-cultivo. Células Jurkat contendo ou não vetor da proteína tat do HIV-1 foram utilizadas como CLTs e co-cultivadas com TIVE-LTCs por 48, 72 e 96 horas. Após extração do RNA total das...(Resumo completo, clicar acesso eletrônico abaixo)

The expansion and growth of towns affect the hydrology of watersheds included in the urban environment, impacting mainly the slopes and river channels. This interference can be in soil waterproofing, the runoff of rainwater, the extinction of surface drainage, the dynamics of flooding processes, etc. For studies concerning the hydrological behavior of watersheds, Remote Sensing techniques have been used to support the acquisition and analysis of data and also to generate new information from the integration of these data. In this context, the study aimed to characterize scenarios and conduct comparative analysis of urban occupation of parts of watershed the Córrego da Servidão, in Rio Claro (SP) and analyze the degree of waterproofing on the ground. With the support of the soil categories of waterproofing listed in Soil Conservation Service (S.C.S / USDA) this analysis was conducted, considering the scenarios of 1958 and 2006, through processes of interpretative analysis of panchromatic and color images aerofotogramétricas. The analysis, data integration and mapping of the watershed area were conducted in an environment of a Geographic Information System (GIS). Maps were obtained to characterize land cover in the watershed, showing the evolution of urban occupation, as well as indicating the densely built and waterproofed

Radiotherapy is a branch of medical physics related to the treatment of malignant neoplasm, being an important instrument in the fight against cancer, when combined with the effort of a multidisciplinary team, composed of, physicians, physicists, nurses and technicians. Every year more than 3.5 million new cases of cancer are recorded in the world, being the prostate cancer responsible for approximately 25% of this amount (INCA and IARC, 2008). In this type of cancer, radiotherapy is a method indicated for treatement. The technological advance in this area over years has allowed a greater accuracy in the tumor location, more conformation of the radiation beam around the tumor, reducing the dose in healthy tissues and a consequent dose increase on treatment (Bedford et al., 1999). A radiotherapy planning, in which the physicist develops an important role, is composed of several steps, including choosing the best configuration of treatment beams. This choice has a close relationship with success of therapy and is critical to achieve the best distribution of dose inside the tumor and expose the least as possible the healthy tissue to radiation. In this work, two options for setting up camps in the first phase in a treatment of prostate cancer were simulated in computer planning: 4 fields orthogonal or “Box” with gantry angles in 00, 1800, 2700 e 90° and 4 fields angled or “X” (1350, 450, 3150 e 2250). The percentage of the rectal volume exposed to 40, 50, 60, 72 and 76 Gy should be limited to 60, 50, 25, 15 and 5% respectively (Greco et al., 2003). The femoral toxicity have limited dose by 70% of the total dose prescribed in a prostate treatment (Bedford et al., 1999). The planning of 27 patients with prostate adenocarcinoma submitted to 3D conformal radiotherapy were accompanied. As a result, it was assessed that the best TCP (tumor control probability)...
