The massive urbanization and activities arising from the uncontrolled growth of urban areas, result in changes on the climate, making it unhealthy. One factor that contributes to poor quality of life due to this fact is the islands of heat that consists in the accumulation of surface heat and raises the temperature in the cities. The vegetation consists of urban greening, urban forests and green areas, have the function to minimize this effect. To reconcile these factors, collected data on surface temperature by satellite images, LANDSAT 5 captured on 18/12/2012 point 75 e 76, orbits 221, band 6 and on-site survey with thermo-hygrometer, possessed the data, crossing the conducted vegetative survey and provided a management vision to improve the microclimate of the city under study. The vegetation coverage at urban area directly affects the ambient temperature, improving the urban micro-climate. The different analyzed surface coverage also affects the apparent temperature. Among the studied ranks, the eucalyptus cultivation, native forest, urban area and solo exposed areas with greater vegetation cover have mild temperatures and improved microclimate.

In the pumping pipelines the located load losses are very important since they have direct influence on hydraulic design of an irrigation system, especially regarding the concentric reducers used in the distribution lines. Hence this work was conducted in the Laboratório de Hidráulica do Centro Federal de Educação Tecnológica de Uberaba. We analyzed 03 concentric reducers PVC 75 x 50 mm, 50 mm and 35 x 35 x 1 "operating at different flow rates. The performance of the tests with the variation of flow in every situation possible to obtain equations to estimate the loss. The equation models presented a high setting, thus enabling the determination of the localized head loss in a situation closer to field reality. For the reduction of 75 x 50 x 35 mm and 50 mm at a flow rate 16.97 m³ h-1 the pressure drop reduction was obtained respectively 0.9263 and 2.7408 mca. To the reduction of 35 x 1 "at a flow rate of 6.02 m³ h-1 was obtained 2.9304 mca pressure drop reduction. The located losses produced by these reductions are relatively high and should be considered with great discretion in hydraulic design of the irrigation system.

Electrical conductivity has been proposed as a rapid test to evaluate seed vigor; however, few researches have emphasized methodologies to its use in seeds of medicinal plants, such as chamomile. The objective of the research was to evaluate the electrical conductivity of chamomile seeds affected by different imbibition times and sample size. The evaluations consisted of moisture content, germination and vigor (first count of germination) to seed initial characterization. Then, it was evaluated the electrical conductivity, affected by imbibition time (6, 12, 24 e 48 hours) and seed amount per sample (25, 50, 75, 100). The completely randomized design was used with four replications, arranged as a 4 x 4 factorial. Means were compared by the Tukey test at 5% of probability. It was concluded that the electrical conductivity of chamomile seeds is affected by the number of seeds per sample and imbibition time isolately.
