Coeficiente de operación de un sistema formado por un refrigerador doméstico acoplado a un acumulador de agua caliente para la recuperación de energía

An experimental apparatus containing a domestic refrigerator coupled to a vertical hot water storage tank was used for energy recovery. The original condenser of the refrigerator was maintained, but modified with a concentric tubes heat exchanger with countercurrent water and refrigerating gas flows. The coefficient of performance for the heat pump is calculated by the ratio of energy in the heat storage and the electric power consumed by the domestic refrigerator compressor. The results show that the increasing of hydrostatic pressure in the storage tank increases the water flow rate and the coefficient of performance. The proposed device also reduces the heat dissipation to the surroundings. This is more important in small confinements found in low-cost houses.

The University and its libraries: Reactions and resistance to scientific publishers

This paper addresses the relationship of copyright and the right of universities on scientific production. Information and Communication Technologies (ICTs) are causing many changes in the system of scientific communication, such as the creation of Institutional Repositories that aim to gather scientific production in digital format. The University needs quicker ways of spreading academic production and many questions are emerging due to contexts such as the Open Access movement. Thus, this paper questions the positioning of Universities, especially Public Universities, which despite having policies related to intellectual property to protect the transferring forms of research results to society; many times do not have a positioning or a mechanism that regulates the self-deposit of scientific production in these Institutional Repositories. In order to develop this paper, the following issues are addressed: lack of interest of the University in storing scientific production; reports on the relationship of the library with scientific publishing houses; the participation of faculty members and students in supporting the Free Access movement; and initiatives aimed at greater flexibility of copyright to the context of scientific production. In order to follow the development of these issues at international level, it was opted for qualitative research with non-participating direct observation to carry out the identification and description of copyright policy of important publishers from the ROMEO SHERPA site; therefore, it can be observed that there are changes regarding the publishers' flexibility before self-archiving of authors in open access institutional repositories in their universities. Given this scenario, we presente reflections and considerations that involve the progress and mainly the integration of the University and its faculty members; the institution should recommend and guide its faculty members not to transfer their copyrights, but to defend their right of copy to Institutional Repositories along with Publishing Houses.

Avaliação de diferentes inclinações e exposições de telhado em três tipos de cobertura em modelos reduzidos de instalações zootécnicas

The present study was developed in Departamentos de Engenharia Rural e Morfologia e Fisiologia Animal da FCAV/Unesp. The objective of evaluating different roof slopes and exposure in three types of coverage in models of animal installations. Project 48 built reduced models of wood were used with dimensions of 1,00 x 1,00 x 0,50 meters. The covering was one water, lateral and wood floor, disposed in the exhibitions North-south, being 24 prototypes in the north exhibition and 24 in the south. Were used in the covering roofs of ceramic type, galvanized steel and asbestos. The slopes varied of 20, 30, 40 and 50% for ceramic tile and 10, 30, 40 and 50% for the others and with two repetitions for slope. Inside the reduced models temperature readings were accomplished, of hour in hour during one year, for the system of acquisition of Data Logger Campbell Scientific-Ínc and externally the temperature of the air, incident radiation global solar, precipitation, speed and relative humidity of the air were measured. The results obtained during the experimental period of one year were appraised statistically for the statistical package SAS in the factorial outline, where three factors were considered: tile type, slope degree and exposure. The obtained averages were compared through the test of Tukey to 5% of probability. After analyzing the data we found that with increasing slope, there was a decrease in inside temperature in the cover prototypes, therefore, using steeper slopes with 50% of tipping ceramics and asbestos, with greater coverage on display South, we have lower temperatures in poultry houses in the geographic coordinates of the city of Jaboticabal.

Frequência de ocorrência de cavidade anoftálmica na região centro-oeste paulista e características dos portadores

Purpose: To observe the frequency of the occurrence of the anophthalmic socket in the Middle West region of the state of São Paulo and to describe the demographic profile of the carriers in a population-based data. Methods: A cross-sectional study involve a random sampling carried out in twelve cities of the Middle West region of the state of São Paulo, for which the reference center is the city of Botucatu was done. The participators were chosen by assortment which considered the houses of these people. It was established a sampling with 11,453 people. All the exams were realized using a Mobile Ophthalmologic Unit. The research protocol included the demographic data and the complete ophthalmologic exam (anamnesis, ocular and systemic antecedents, familiar antecedents, visual acuity with and without correction, tonometry, biomicroscopy, fundoscopy, and refraction exam). All the data were transferred to an Excel spreadsheet and submitted to a descriptive analysis and were presented by the frequency of the occurrence. Results: Ophthalmic socket frequency in the Middle West region of the state of São Paulo was 0.96%. We found 11 cases of anophthalmic socket, with involvement of 0.7 % in females and 1.3 %, male. The most common causes of anophthalmic socket were glaucoma (blind painful eye), microphthalmia, trauma, and endophthalmitis. The majority of the people were 40 years old or more, and we found just one person younger than 19 years old. Conclusion: The anophthalmic socket occurred in 0.96% of the habitants of the Middle West region of São Paulo State, occurring mainly in male and with large variety of the affected ages.
