Abstract: Determining the levels of heavy metals in honey is a measure to control its quality. The objective of this study was to determine the contents of Cd, Cu, Pb and Zn in honey of stingless bee. The differential pulse anodic stripping voltammetry (DPASV) was used to determine the trace elements in honey samples. Pb was detected in 100% of the samples, Cu and Zn in 98.15%, and Cd only in 33.33%. The trace elements analyzed detected in the samples remained within tolerable levels in foods for human consumption.

Silva, Carlos Alberto Figueiredo da;Lopes, José Pedro Sarmento Rebocho;Araújo Netto, Jacques de;
Motriz: Revista de Educa??o Física , 2010, DOI: 10.5016/1980-6574.2010v16n4p995
Abstract: this study analyzes the data on the science and technology ministry of brazil's portal for innovation. the aim is to understand the process of the physical education innovation. we use the argument triple helix as theoretical framework to evaluate the synergy between university-industry-government in the physical education's field of research. the methodology was guided by the literature and document's research. the results allow us to infer that the area of physical education research is typically multidisciplinary. there is a significant number of researchers and research groups, however, there are no related industries. the non-participation of the industries indicates that physical education is far from the productive sector, which highlights the today's inability to raise funds for the survey of this sector, and involve it in schemes that enable innovation and development projects from research activities.

Abstract: O crescimento da violência, a preocupa o mais intensa dos cidad os pela busca da seguran a e as estratégias gerenciais adotadas por organiza es privadas contribuíram para que as organiza es policiais adotassem um novo modelo de policiamento - "o policiamento comunitário", com foco na parceria entre a sociedade e a polícia para juntos melhorarem a sensa o de bem-estar das pessoas. Este artigo tem como objetivo analisar, sob a ótica da teoria da cadeia de meios e fins, a estrutura de valores dos usuários dos servi os de policiamento comunitário: o Ronda do Quarteir o na cidade de Fortaleza (CE), tomando como base a identifica o de atributos do servi o percebidos por estes usuários e das rela es entre os atributos e suas consequências na utiliza o do servi o com os valores pessoais dos indivíduos. Utilizou-se a técnica de laddering que permite a constru o do mapa hierárquico de valor, evidenciando os elementos que caracterizam o comportamento dos consumidores ao utilizarem tal servi o. Os resultados mostram a preocupa o dos usuários dos sevi os do Ronda do Quarteir o em atingir o bem-estar que poderá ser adquirido na realiza o dos valores: amar o que faz, amizade, cidadania, defender a pátria, felicidade, honestidade, satisfa o, seguran a e sentir-se útil à sociedade. The increase of violence, the more intense citizen's search for security contributed for a new model of police offered by government which is the "community police". This kind of police is developed in many countries in order to create a close relationship with the society. It is focused on the partnership between society and police to develop jointly an improved people's welfare. This paper's objective is to make an analysis, under the means end-chain theory, of the values structure of the users of "Block patrol" a community police created in a capital city of the northeast of Brazil. First, this study identifies the main attributes of the services as attendance speed, nice clothing, credibility. The second step was to relate these attributes to the consequences to the user. These main attributes perceived by these users and the relation between these and its consequences lead to the values. The laddering technique was used which allowed the construction of the hierarchical value map showing the user's behavior after the service experience. This map shows the main relationship with the attributes, consequences and values, allowing insights to an effective communication strategy. The values identified were: love, friendship, citizenship, happiness, honesty and satisfaction.

In order to assess ivermectin action upon migratory larvae, group I (60 mice) was equally split in three subgroups, namely I-A, I-B, and I-C. On the 7th day after inoculation (DAI), each animal from the subgroup I-A was treated with 200 μg/Kg ivermectin while subgroup I-B was given 1,000 μg/Kg, both groups received a single subcutaneous dose. To assess the drug action on encysted larvae, group II was equally split in three subgroups, namely II-A, II-B, II-C. On the 45th DAI each animal was treated with ivermectin at 200 μg/Kg (subgroup II-A) and 1,000 μg/Kg (group II-B) with a single subcutaneous dose. Untreated animals of subgroups I-C and II-C were used as controls. On the 60th DAI all animals were submitted to larva search. At a dose of 1,000 μg/Kg the drug had 99.5% effectiveness on third-stage migratory larvae (subgroup I-B). Ivermectin efficacy was lower than 5% on third-stage encysted larvae for both doses as well as for migratory larvae treated with 200μg/Kg.

Abstract: the viability of a formulation of the fungus monacrosporium thaumasium associated with ivermectin was evaluated for the biological control of bovine gastrointestinal nematode parasites. four groups of five calves each were placed in pastures with a stocking rate of 1.6 animal/hectare. in group 1 (control), the calves did not receive any treatment. in group 2, each animal received 20g of pellets of m. thaumasium orally twice a week during a six-month period that began with the onset of the rainy season (october 23, 2000). in group 3, each animal received 20g of pellets of m. thaumasium orally twice a week during the same period as 2, as well as two strategic treatments with ivermectin (200 mcg/kg) on may 10, 2001 and july 5, 2001. in group 4, the animals were treated with ivermectin alone as described for group 3. epg counts for group 1 were significantly greater (p< 0.01) than those for groups 2 and 3 and the difference at the end of the study period was near 100%. the epgs of group 4 animals remained high until the first strategic treatment with ivermectin. values for groups 1 and 4 differed significantly (p< 0.05) from those of groups 2 and 3 from december 2000 onwards. it was concluded that the use of this dose and periodicity of application of m. thaumasium pellets makes the application of anthelminthic treatments unnecessary.
