Environmental factors influencing the distribution of three species within the genus Persephona Leach, 1817 (Crustacea, Decapoda, Leucosiidae) in two regions on the northern coast of Sao Paulo State, Brazil

Patterns of spatio-temporal distribution of Brachyura are determined by the interaction among life history traits, inter and intraspecific relationships, as well as by the variation of abiotic factors. This study aimed to characterize patterns of spatio-temporal distribution of Persephona lichtensteinii, Persephona mediterranea and Persephona punctata in two regions of the northern coast of Sao Paulo State, southeastern region of Brazil. Collections were done monthly from July 2001 to June 2003 in Caraguatatuba and Ubatuba, using a shrimp fishery boat equipped with double-rig nets. The patterns of species distribution were tested by means of redundancy analysis (RDA) and generalized linear mixed models (GLMM) in relation to the recorded environmental factors (BT: bottom temperature, BS: bottom salinity, OM: organic matter and granulometry (Phi)). The most influent environmental factor over the species distribution was the Phi, and the ascendant order of influence was P. lichtensteinii, P. punctata and P. mediterranea. The greater abundance of P. mediterranea showed a conservative pattern of distribution for the genus in the sampled region. The greater occurrence of P. punctata and P. lichtensteinii, in distinct transects than those occupied by P. mediterranea, seems to be a strategy to avoid competition among congeneric species, which is related to the substratum specificity.

Análise granulométrica do compósito cimentício produzido com adição de resíduos de madeira e escória

Since the early twenty-first century, the construction sector has been the second largest on the rise in the Brazilian industrial sector, with a growth of 1.4% in 2012, and is likely to remain at this level for a long time. However, unlike decades ago, the industry has been seeking in its manufacturing process, sustainable materials, encompassing in their works the concept of sustainability. Thus, the timber sector seeks to satisfy a market increasingly demanding, innovating techniques and utilization being less aggressive to the environment. The purpose of this study was to produce and evaluate the mechanical strength of the composite cement with the addition of wood residues and slag low oven. Therefore, it was made 42 specimen cement-slag-wood, carried out in two steps. Since at the first, it was varied only the slag particle size, and at the second, through the best result of the previous step, it was varied the wood particles granulometry. The mechanical performance of the composite was evaluated by the results obtained in the compression test and the physical test for determining the density of the material. In the first step of the process can be concluded that the best result was achieved with the use of slag particles retained on the 60 mesh sieve. In the second phase of the study concluded that the best results were achieved with wood particles with the large particles, i.e. particles retained on the 10 mesh sieve. Both in the first and in the second step it can be seen that there has been the influence of the particle size of the waste materials. With the obtained results, could be evaluated that the use of waste for the production of cement-slag-wood composite showed lower performance when compared to the results obtained in studies without the use of waste. However, some applications are feasible to be performed with the use of composite wood-cement-slag

Avaliação da vulnerabilidade a contaminação das águas subterrâneas do aquífero Rio Claro na mineração Mandu, distrito de Ajapi - Rio Claro-SP

Groundwater in the Rio Claro district is predominantly extracted from low productivity wells on the Itararé Aquifer, from depths greater than 150 m. These factors in conjunction with increasing demand for water supply have stimulated many industries to exploit the Rio Claro Aquifer, constituted by Cenozoic sediments of the Rio Claro Formation, where hydraulic properties are poorly known. For this reason, it is necessary to study the possible vulnerable to contamination punctual locations of the aquifer, in order to enable proper management of these groundwater reserves and to allow continuity of supply. Thus, this study aims to assess the vulnerability to groundwater on contamination Rio Claro Aquifer, punctually in Mandu mining site area, located in the District of Ajapi, Rio Claro - SP, the company which operates and sells industrial sand. The risk of groundwater contamination depends on the relationship between the hydrogeological characteristics of the aquifer layer (vulnerability to contamination) and the pollutant load. To evaluate the susceptibility to contamination it was applied the method GOD (FOSTER and HIRATA, 1987; FOSTER et. al., 2002) and, in addition, field and laboratory tests were performed to chacacterize the granulometry of the strata, hydraulic conductivity and some physical indices to make the evaluation more assertive and detailed. Punctual contamination vulnerability found in the aquifer Rio Claro, was moderate, which means that the aquifer is vulnerable to some contaminants, but when continuously discharged or leached. Thus, Mandu mining has a great role on preventing the emission of contaminants in the process of extraction and processing of sand... (Complete abstract click electronic access below)
