Buildings structures and surfaces are explicitly being used to grow plants, and these "urban plantings" are generally designed for aesthetic value. Urban plantings also have the potential to contribute significant "ecological values" by increasing urban habitat for animals such as arthropods and by increasing plant productivity. In this study, we evaluated how the provision of these additional ecological values is affected by plant species richness; the availability of essential resources for plants, such as water, light, space; and soil characteristics. We sampled 33 plantings located on the exterior of three buildings in the urban center of Brisbane, Australia (subtropical climatic region) over 2, 6 week sampling periods characterized by different temperature and rainfall conditions. Plant cover was estimated as a surrogate for productivity as destructive sampling of biomass was not possible. We measured weekly light levels (photosynthetically active radiation), plant CO2 assimilation, soil CO2 efflux, and arthropod diversity. Differences in plant cover were best explained by a three-way interaction of plant species richness, management water regime and sampling period. As the richness of plant species increased in a planter, productivity and total arthropod richness also increased significantly likely due to greater habitat heterogeneity and quality. Overall we found urban plantings can provide additional ecological values if essential resources are maintained within a planter such as water, light and soil temperature. Diverse urban plantings that are managed with these principles in mind can contribute to the attraction of diverse arthropod communities, and lead to increased plant productivity within a dense urban context.

This paper focuses on the implementation of a geological and geotechnical mapping to the planning of the region stream Bertini, territorial expansion area of the municipality of Americana (SP), a medium-sized city in the countryside of Sao Paulo state, with great potential for growth industrial and residential. To this end, based on the methodology established by the Institute for Technological Research, the charters geological and geotechnical aimed at exposing the capabilities and limitations of the soil. The analysis of similar soil characteristics such as geology, geomorphology, slope, geotechnical testing and the current use and land cover was possible to recognize four geotechinical units. The units I and III are related to areas of top and concave and convex parts of the study area, shown to be sites of low occupancy restriction. However the units II and IV, respectively allocated in the floodplain of the Piracicaba River and the banks of the stream Bertini and some of its drainage, showed a more restricted area due to proximity to water bodies and drainages that offer higher slopes.

Health Care Waste (HCW) represents 1%, and it has presently gained a lot of importance. Adequate management is one of the great challenges to be faced by health care centers. It has gained distinction and been widely discussed by members of the sectors involved with sanitation, public health and environmental issues due to waste physical, chemical biological characteristics, which pose potential risk to the environment and public health. The present study aims at evaluating HCW internal management by following all its phases, determining indicators, classifying and quantifying, establishing production rates (kg /patient/day) for the sector and designing materials to disseminate appropriate HCW disposal in the Emergency Room of the UNESP University Hospital in the city of Botucatu according to the guidelines presently in force. : From June to October 2011, the waste flow was observed from its production to final disposal. Four weight measurements were performed on four consecutive days in the month of August by using a properly calibrated (in grams) digital scale at the times scheduled for collection of the produced waste. Hence, the daily and monthly amounts were estimated according to their classification. All the waste packaged in the bags in garbage cans in the Emergency Room for a 24-hour period was considered to be a sample. Separation was not adequately performed in that sector, and waste from Group A was mixed with that from Group D. The amount of infectious waste produced in the sector corresponded to 87.80 %, common waste to 10.93 % and recyclable waste to 1.27%. The mean daily HCW production was of 123.300 kg/day, and the total monthly production was of 3,822 kg/month, which was distributed as follows: Group A 3,355,750 kg/month; Group D 417,570 kg/month and recyclables 48,670 kg/month. The production rate corresponded to 0.47 kg/patient/day, thus showing... (Complete abstract click electronic access below)
