Abstract: A repelência de inseticidas botanicos tem se destacado como uma tática promissora no controle alternativo de pragas agrícolas e urbanas, podendo ser um dos componentes do manejo integrado de pragas. Objetivou-se com este trabalho identificar a repelência de inseticidas botanicos sobre fêmeas ápteras de Aphis gossypii Glover. Testes com chance de escolha foram realizados com discos de folha de algodoeiro, imersos nas caldas dos inseticidas e testemunha (água destilada com DMSO a 2%). Utilizou-se azadirachtina (0,075%) e os óleos essenciais de Piper hispidinervum CDC, P. aduncum L., Cymbopogon winterianus (L.), C. citratus (D.C.) Stapf, Foeniculum vulgare Mill, Syzygium aromaticum (L.) Merrill e Perry, Cinnamomum zeylanicum Blume, Schinus terebinthifolius Raddi e Chenopodium ambrosioides L. na concentra o de 0,05%. C. citratus, C. winterianus, P. aduncum, S. terebinthifolius, azadirachtina e C. zeylanicum apresentaram os maiores percentuais de repelência, 100; 84; 66,67; 64; 60,87 e 48% respectivamente e reduziram a produ o de ninfas em 100; 92; 42,9; 87,5; 80,65 e 89,74%, apresentando resultados significativos pelo teste do χ2 ao nível de 10% de probabilidade. Nos testes com F. vulgare (χ2 = 3,66, P = 0,05) as fêmeas de A. gossypii foram atraídas significativamente para os discos tratados e ocorreu um aumento na produ o de ninfas nos resultados obtidos para F. vulgare (χ2 = 5,87, P = 0,02) e C. ambrosioides (χ2 = 14,31, P = 0,001). The repellence of botanical insecticides has emerged as a promising technique in the alternative control of urban and agricultural pests, being seen as one component of integrated pest management. The aim of this work was to identify the repellence of botanical insecticides on apterous females of Aphis gossypii Glover. Random-choice tests were carried out with discs from the leaves of cotton plants immersed in insecticide solution and in a control (distilled water with 2% DMSO). Azadirachtin was used (0.075%) and the essential oils of Piper hispidinervum CDC, P. aduncum L., Cymbopogon winterianus (L.), C. citratus (DC) Stapf, Foeniculum vulgare Mill, Syzygium aromaticum (L.) Merrill and Perry, Cinnamomum zeylanicum Blume, Schinus terebinthifolius Raddi and Chenopodium ambrosioides L. at a concentration of 0.05%. C. citratus, C. winterianus, P. aduncum, S. terebinthifolius, azadirachtin and C. zeylanicum showed the highest percentage of repellence, 100, 84, 66.67, 64, 60.87 and 48% respectively, and reduced nymph production by 100, 92, 42.9, 87.5, 80.65 and 89, 74%, with significant results from the χ2 test at 10% probabilit

Abstract: background: heavy episodic drinking has been shown to be closely associated with considerable damage to and burden on society. objectives: this review aims to give an overview of the brazilian reality based on socio-demographic aspects, considering individual and social factors related to heavy drinking. methods: a computer-assisted search of relevant articles was conducted in the foremost scientific databases. results: males tended to heavy drinking more frequently than females. heavy episodic drinking was most prevalent among adolescents and young adults, though this prevalence tended to level off as they age. socioeconomic conditions appear to have an effect on heavy drinking. the early onset of heavy drinking has been associated with a history of alcohol dependency in the adult phase. heavy episodic drinking coincided with other psychoactive substance usage. motives for heavy drinking included both social activities as well as the availability of money. peer pressure was one of the strongest influencing factors in binge drinking and seemed to outweigh parental influence, particularly from late adolescence onward. heavy drinking also varied according to both the predominant adult and adolescent drinking culture, with more binge drinking in the southern areas of brazil as compared with the northern and central regions. conclusions: a myriad of socio-demographical, individual, and social characteristics associated with heavy drinking have been identified. however, knowledge in these areas remain limited, as most research has been conducted on specific groups and situations, in particular, that of north american college students. more research in brazil is urgently needed, as results from other cultural contexts should not be generalized.

Abstract: the present paper brings considerations on the development in the infant's early years, counterposing important points within the psychoanalytic theory and objectal relations theory, as well as focusing contemporary authors. aspects such as the importance of early relations, a brief history of neonatal care procedures and the mother-infant interaction in risk birth situations, especially in cases of premature birth, are approached. in these situations, the processes of formation of initial links and affection can pose difficulties. we mused about the potential interventions for promotion and prevention in collective health, directed at families that have their infants hospitalized at the neonatal intensive care unit, seeking a better life quality for those involved in this process. formulations that may come to prevent the emergence of general developmental disorders are mentioned, suggesting that they give rise to questions to be discussed in the field of collective health care.

Abstract: this article analyzes the development of instruments for coordination between the family health strategy and other levels in the health system, with a focus on measures to promote coordination linked to the "integration among levels of care". the results of case studies in four large cities indicate the presence of mechanism for integration among levels of care, suggesting concern with guaranteeing comprehensive care. the principal strategies identified here were: creation and strengthening of regulatory structures in the municipal health secretariats and family health units with decentralization of roles to the local level, organization of flows, electronic patient charts, and expansion in the supply of specialized services at the municipal level. however, lack of integration among different providers, insufficient formal flows for hospital care, and absence of policies for medium complexity care were detected as barriers to the guarantee of comprehensive care, making the network's integration incomplete.

Abstract: this study aimed at analyzing the plankton biomass found in a piggery waste treatment system, composed of a high rate algal pond (hrap), two maturation ponds (mp1, mp2) (system a) and a water hyacinth pond (whp) (system b). the ponds were disposed in series and the study was performed for 32 weeks. the physicochemical variables monitored were: ph, temperature, dissolved oxygen, soluble chemical oxygen demand, nitrogen compounds and total phosphorus. the plankton biomass was identified at genus level and the ecology index was calculated so as to describe its development in the ponds. results showed lower specific richness, which was associated to the mono-specific chlorella sp population. the protozoa density was conversely proportional to the green algae density. the higher species diversity occurred in the whp and mp2. the green algae presented high relative density (>97 %). the jaccard index reached 100% if chlorella sp and sometimes diatoms were found in the system's inlet and outlet. the productivity of algal biomass was lower than 10 gtss/m2/d in the maturation ponds, which was maintained in the hrap. the green algae coefficient of variation (cv) varied from 0 to 1.5 in the hrap and whp, but was constant at 0.9 to the 10th week in mp1 and around 0.5 during all the experimental period for mp2. for the chlorophyll a, this coefficient varied in all the ponds.
