Peripartum or Transition Period is, generally, defined as the period between three weeks pre-calving and three weeks after calving. It is a critical and crucial stage to the cow’s health and to economic profitability during the lactation. During this phase the cows experience several changes that prepare them to calve and milk yield. These changes contribute to metabolic disorders’ incidence, and can lead to reproductive function and milk yield reduction, and increase the herd’s disposal. This paper aimed to review the peripartum metabolic diseases, which includes Ketosis, Hypocalcemia, Hepatic Steatosis, Ruminal Acidosis and Lameness

Increasingly the business for large companies tend to sustainable actions. Such actions may have motivated social, environmental and economical too. Thus, the study of small actions or investments aimed at improving a product or a process may impact on financial return and even the exposure of a sustainable paper company, a fact that is increasingly wel l regarded in the market. This study presents proposals raised in the market and in the literature showing the cost of each investment, the payback over time and the benefits of each project to be implemented in a corporative building located in the city of São Paulo. It was analyzed the energy consumption, determining the amount of consumption of each device through measurement of some parameters such as voltage and operating current, and lifting nominal values supplied by the manufacturers. By understanding the conditions of each equipment and the processes involved, were raised possible energy improvements, focusing on the cooling system of the building, the tariff system and the installation of an energy management system

The use of rainwater for non-potable purposes generates a reduction in the consumption of treated water, however, this reduction is not observed in the generation of wastewater, as this is independent of the water source. In Brazil, the pricing on the services of collection and treatment of sewage, in general, is based on the coefficient of return of the sewage disposal system, which has a relation sewer / water proportional to the consumption of treated water measured at the consumer unit. The use of rainwater originating from utilization systems infer on the coefficient, underestimating the volume of wastewater generated. Therefore, this study presents a methodology for setting the coefficient of return. Different roof areas, reservoir volumes and rates of water consumption situations were simulated. The behavior of adjustment of the coefficient of return were also analyzed for the average area per capita roof (m² / inhabitant) of Rio Claro - SP. As a result, it can be seen that the adjustment of the coefficient of return is directly proportional to the increase of the roof areas and the volumes of reservoirs, and inversely proportional to the total water demand. The corrected coefficient of return showed the minimum value of 0.83 and a maximum value of 1.45, this variation corresponds to the maximum ratio between the demands of total water and rainwater, since the exploitation of rain water should be used only for non-potable uses, according to NBR 15527 / 07. To the municipality of Rio Claro - SP was noted an adjustment of the coefficient of return ranging from 0.99 to 6.61

This written report narrates the process of writing the report “A caminho da cidade” (in English: “Going to the city”), submitted as Final Papers by Naomi Oliveira Corcovia, Journalism Student at UNESP. The author tries to elucidate how much the urbanization, the industrialization and other postmodern process have influenced São Paulo´s countrymen´s life and behavior. But before, the author studied the stereotype of the countrymen diffused by Media and Brazilian literature

Seeking the integrated management of water resources and financial compensation especially as a management tool, according to the Law No. 9433 of 1997 and No. 9985 of 2000. This research's main objective is measuring the flow contribution of Núcleo Santa Virginia, the State Park of Serra do Mar, starting from the hydrological regionalization method, developed by the Department of Water and Power. According to the Law 9985 of 2000 Conservation Units have the right to receive in the form of an investment a portion of the amount paid by Power Plants, being passed directly to the Conservation Units, differently from the 9433 Act. By dividing the area of Núcleo Santa Virgínia, in Sub-basins, it was possible to find the minimum flow during seven consecutive days, with a return period of ten years, Q7,10, and steady water flow in 95% of the time, Q95 for the Center and from these data to calculate the monetary value of law under Articles 47 and 48 from Law 9985 of 2000
