13. Variabilidade espacial e manejo localizado de plantas daninhas em pomar de pereiras
Weeds can negatively affect the quantity and quality on orchards fruit yield. They usually occur in clusters in a given area, not evenly distributed throughout the entire field. Thus, the site-specific application of herbicides makes possible the use of control methods, decreasing the entire cost. In this work, both spatial and temporal variability of broad-

14. Development of a Multimetric Index of Ecological Integrity for streams in the urban area of Campo Grande (Mato Grosso do Sul), based on benthic macroinvertebrates / Desenvolvimento de um Índice Multimétrico de Integridade Ecológica para córregos na área urbana de Campo Grande (Mato Grosso do Sul), baseado em macroinvertebrados bentônicos
Water pollution is a growing problem, especially in the water courses that flow through urban centres, receiving residential, commercial and even industrial effluents. The small amount of control that exists is often done by means of physical, chemical and bacteriological analyses. The lack of a biological alternative may be due to the paucity of research in

15. Determinação de Sn(II) por polarografia: aplicação no controle de qualidade de reagentes liofilizados para radiodiagnóstico / Polarographic determination of Sn(II): application in the quality control of radiopharmaceutical reagents
Stannous chloride (SnCl2.2H2O) is the major compound used for reduction of generator-derived 99mTc-pertechnetate in cold kits for on site preparation of 99mTc-radiopharmaceuticals. These cold kits usually contain a ligand, stannous chloride, and different additives. Various techniques were described for tin determination, but they cannot distinguish between

18. Avaliação da qualidade do Rio São Lourenço, SP, sob influência de estações de tratamento de água e estações de tratamento de esgoto / ENVIRONMENTAL QUALITY IN AREA OF INFLUENCE OF MUD OF STATIONS FOR TREATMENT OF WATER AND SEWAGE
For a long time, there was a neglect to water resources, both by society as by the authorities. The rapid increase of population, causing disorderly occupations, was ignored by the public sectors and the society itself, resulting in environmental degradation. Ecotoxicological tests are essential to environmental assessment, together with chemical and biologi

19. Coccinellidae (Coleoptera) usando plantas aromáticas como sítio de sobrevivência e reprodução em sistema agroecológico, e aspectos biológicos em condições de Laboratório / Coccinellidae (Coleoptera) using aromatic plants as survival and reproduction site in agroecological system, and biological aspects under laboratory conditions.
Among the natural enemies of agriculture pests, the Coccinellidae predators are detached. Some coccinellids only complete their development and produce viable eggs and progenies when they consume their preferred prey. However, when this prey is scarce or in presence of a prey of low quality, certain coccinellids feed on alternative food resources, such as ex

20. MESOFAUNA EDÁFICA E A TAXA DE DECOMPOSIÇÃO DA RESTEVA DE TRÊS SUCESSÕES DE CULTURA EM SISTEMA PLANTIO DIRETO
The mesofauna soil is composed primarily of Mite and Collembola (75 to 97% of total arthropod fauna of the soil) is one of the few groups of human beings who show enormous diversity of forms, habitat and behavior, being found in almost all places accessible to wildlife because they live in regions epi, hemispheric and euedáficas. The components of mesofauna

21. Theoretical model to control on site the uplift capacity of helical screw piles embedded in sandy soil / Modelo teórico para controle da capacidade de carga à tração de estacas metálicas helicoidais em solo arenoso
Empirical correlations between installation torque and uplift capacity of helical screw piles are routinely used as a procedure for quality control on site of this type of foundation. In this work, a theoretical model of the relationship between uplift capacity and installation torque of deep helical screw piles in sand was presented to be used as a quality

22. Poluição atmosférica por emissão de material particulado: avaliação e controle nos canteiros de obras de edifícios. / Particulate matter air pollution: evaluation and control on buildings construction sites.
The construction sites cause many environmental impacts related to high consumption of resources and high levels of pollutions emissions, affecting the whole society. Among these pollutions, it is the particulate matter emission in the atmosphere, responsible for heart and lung diseases, damages to animals, plants, soil, water and air quality and nuisances t

24. Influência do agregado graúdo reciclado de resíduos da construção predial nas propriedades do concreto fresco e endurecido
Recycling waste materials is an efficient way to hinder environmental, social and economic impacts of the civil construction industry. This dissertation aimed at verifying the behavior of different concretes made of coarse recycled aggregate (AGR), mineral fractions collected from the waste (RCD) of a high- rise apartment building (multiple floor building).
