Abstract: the covering of the soil is an agricultural practice that intends to control the harmful herbs, to reduce the losses of water by evaporation of the soil, and to facilitate the harvest and the commercialization, once the product is cleaner and healthier. however, when the soil is covered important microclimatic parameters are also altered, and consequently the germination of seeds, the growth of roots, the absorption of water and nutrients, the metabolic activity of the plants and the carbohydrates storage. the current trial intended to evaluate the effect of soil covering with blue colored film on consumptive water-use in a lettuce crop (lactuca sativa, l.). the experiment was carried out in a plastic greenhouse in araras - s?o paulo state, brazil from march 3rd, 2001 to may 5th, 2001. the consumptive water-use was measured through two weighing lysimeter installed inside the greenhouse. crop spacing was 0.25 m x 0.25 m and the color of the film above soil was blue. leaf area index (iaf), was measured six times (7; 14; 21; 28; 35; 40 days after transplant) and the water-use efficiency (eu) was measured at the end. the experimental design was subdivided portions with two treatments, "bare soil" and "covered soil". the average consumptive water-use was 4.17 mm day-1 to the "bare soil" treatment and 3.11 mm day-1 to the "covered soil" treatment. the final leaf area index was 25.23 to the "bare soil" treatment and 24.39 to the "covered soil" treatment, and there was no statistical difference between then.

Abstract: INTRODU O: A cárie dentária é a doen a de maior prevalência da cavidade bucal gerando graves conseqüências econ micas e sociais. Estudos de prevalência de cárie dentária devem ser realizados periodicamente para o adequado planejamento das a es e servi os de saúde bucal. Assim, objetivou-se realizar estudo para conhecer a prevalência da cárie dentária em municípios do Estado de S o Paulo, Brasil, medida através do índice CPO-D, na idade-índice de 12 anos, no período 1990-1995. MATERIAL E MéTODO: Foram utilizados dados produzidos originalmente por secretarias ou departamentos municipais de saúde, obtidos através de instrumento concebido para essa finalidade, encaminhado aos 625 municípios do Estado de S o Paulo, agrupados segundo o seu tipo e a regi o geográfica a que pertencem. RESULTADOS: Do total de 625 municípios, 237 (37,9%) atenderam à solicita o de informa es e 125 (20,0%) dispunham de dados sobre o CPO-D, correspondendo a cerca de 5 mil crian as de 12 anos examinadas. O estudo revelou que em apenas 4,0% dos municípios a prevalência de cárie dentária é baixa, sendo alta ou muito alta em cerca de 80,0%. A varia o nos valores do índice CPO-D ficou entre 1,3 e 13,6 e a média estimada para o Estado de S o Paulo foi 4,8. Constatou-se ainda que os "grandes" municípios registraram 54,6% das suas popula es enquadrando-se nas categorias de baixa ou moderada prevalência de cárie enquanto nos "pequenos" municípios 87,8% da popula o correspondiam às faixas de alta ou muito alta prevalência de cárie. CONCLUS ES: A pesquisa evidenciou que os servi os municipais de saúde bucal, no estado de S o Paulo, pouco tem se utilizado dos recursos básicos que a epidemiologia pode oferecer, indicando a necessidade de uma adequada forma o de profissionais de saúde bucal na área de epidemiologia, em especial aqueles que exercem atividades de coordena o de servi os.

Abstract: the object of this study was to identify context elements that have an influence on pesticide use, related perceptions, and actions in flower production. the study was carried out in barbacena, minas gerais state. the method used was based on an anthropological fast diagnosis approach inspired on the signs, meanings and actions model and on the analysis of semi-structured interviews with 20 workers from four different flower-growing fields. the field data analysis indicates that these workers face two realities: the need for pesticides and suffering generated by pesticide management. furthermore, there is clearly no direct relation between risk awareness and the effective hazards associated with pesticides. this gap is filled by beliefs which are at the basis of their actions. these beliefs reinterpret information and risk, influence behavior, and make it possible for these workers to move between these two paradoxical realities and pesticide. attributing new meanings to pesticide management risks, however, may imply in positively valuing potentially harmful behaviors.

Abstract: the success of international initiatives for the eradication of measles depends in large part on knowledge about vaccination. in 1992, a cross-sectional study was carried out to evaluate knowledge about measles vaccine among pediatricians in the brazilian city of salvador, bahia. of the 506 pediatricians residing in the city, 299 (59%) could be located and responded to a questionnaire containing 15 questions that posed hypothetical situations regarding indications and contraindications for this vaccine. the average number of correct responses was 9.3 out of 15, which illustrates the pediatricians' poor knowledge of measles vaccine. conditions commonly seen in pediatric practice in brazil-malnutrition, upper respiratory tract infection, diarrhea, and prematurity-were often erroneously considered contraindications for immunization. more than half (62%) of the pediatricians did not know the correct way to administer the vaccine. knowledge about the vaccine did not differ according to the length of time that had elapsed since the physicians' university training in pediatrics or as a result of working in health centers operated by the state health secretariat. university professors, pediatricians with a postgraduate degree, and those pursuing postgraduate studies scored slightly higher than the rest. these results point to the need to strengthen training on measles vaccination in medical schools and programs of continuing education for pediatricians.

Abstract: El éxito de las iniciativas internacionales para la erradicación del sarampión depende en gran medida del grado de conocimiento sobre la vacunación. En 1992 se evaluaron mediante un estudio transversal los conocimientos sobre la vacuna antisarampionosa de los pediatras de la ciudad brasile a de Salvador, Bahia. Del total de 506 pediatras residentes en la ciudad, 299 (59%) pudieron ser localizados y respondieron a un cuestionario de 15 preguntas en las que se planteaban situaciones hipotéticas sobre indicaciones y contraindicaciones de esta vacuna. El promedio de aciertos fue de 9,3 preguntas de las 15, lo que muestra el poco conocimiento de los pediatras sobre la vacunación antisarampiososa. Situaciones comunes en la práctica pediátrica brasile a -desnutrición, infección de vías respiratorias altas, diarrea y estado prematuro- fueron a menudo erróneamente consideradas como contraindicaciones para la inmunización. Más de la mitad (62%) de los pediatras no conocían la vía correcta de administración de la vacuna. Los conocimientos sobre la vacuna no variaron en función del tiempo transcurrido desde la formación universitaria del pediatra o de su trabajo en centros sanitarios de la Secretaría Estatal de Salud. Los profesores universitarios, los pediatras con maestría y los que cursaban estudios de posgrado tuvieron una media de aciertos ligeramente superior a la del resto. Estos resultados indican la necesidad de reforzar la ense anza sobre la vacunación antisarampionosa en las facultades de medicina y en los programas de formación continuada para pediatras.

Abstract: Breast cancer is the most frequent cancer in women in Brazil. Although it is considered a cancer with relatively good prognosis, if diagnosed and treated appropriately, mortality rates from breast cancer remain high in Brazil, most likely because the disease is still diagnosed in advanced stages. The aim of this study was to evaluate the prevalence of breast cancer in a university hospital by pathological examination and the prognostic and predictive factors associated with each case, to observe the stage of diagnosis of patients. We conducted a retrospective study with selection of anatomic-pathological reports of mammary tumor excision diagnosed with breast cancer, from the University Hospital of Presidente Prudente - SP, in the period from 1998 to 2009. We collected the data related to patient age and prognostic and predictors factors. There were 183 cases of breast cancer. The highest incidence occurred between the ages of 40-49 years (29.5%) and the most frequent histological type was invasive ductal carcinoma (61.2%). In 45% of cases, the tumors were measured less than 2 cm. The majority (71%) had no metastasis to axillary lymph nodes. In 27 cases there was expression of hormone receptors and in 26 patients were overexpression of Her2/neu. It is concluded that the patients studied were diagnosed in early stage of breast cancer.

Abstract: Tropical deforestation and forest fragmentation are among the most important biodiversity conservation issues worldwide, yet local extinctions of millions of animal and plant populations stranded in unprotected forest remnants remain poorly explained. Here, we report unprecedented rates of local extinctions of medium to large-bodied mammals in one of the world's most important tropical biodiversity hotspots. We scrutinized 8,846 person-years of local knowledge to derive patch occupancy data for 18 mammal species within 196 forest patches across a 252,669-km2 study region of the Brazilian Atlantic Forest. We uncovered a staggering rate of local extinctions in the mammal fauna, with only 767 from a possible 3,528 populations still persisting. On average, forest patches retained 3.9 out of 18 potential species occupancies, and geographic ranges had contracted to 0–14.4% of their former distributions, including five large-bodied species that had been extirpated at a regional scale. Forest fragments were highly accessible to hunters and exposed to edge effects and fires, thereby severely diminishing the predictive power of species-area relationships, with the power model explaining only ~9% of the variation in species richness per patch. Hence, conventional species-area curves provided over-optimistic estimates of species persistence in that most forest fragments had lost species at a much faster rate than predicted by habitat loss alone.
