Utilization of shells of the snail Achatina fúlica Bowdich, 1822 (Mollusca, Gastropoda) by the hermit crab Clibanarius vittatus (Bosc, 1802) (Decapoda, Anomura) in the São Vicente Estuary, São Paulo, Brazil

Hermit crabs depend on mollusc shells for housing. In this study, an unusual resource is reported for a hermit crab that usually inhabits marine gastropod shells. During a field study conducted from May 2001 to April 2003 in an estuarine area in São Vicente, state of São Paulo, Brazil, 21 individuals of Clibanarius vittatus (Bosc, 1802) were found inhabiting the shells of the terrestrial gastropod Achatina fullea Bowdich, 1822. A. fúlica occurs in nearshore grass patches, where occasional contact with sea water kills them, and their shells then become available to the hermit crabs.

Desempenho térmico de aviário de postura acondicionado naturalmente

The work aimed at presenting analyses and comparisons of the thermal performance of a laying hens housing in the region of Bastos, in the state of São Paulo, adapted from natural alternatives of acclimatization, having a not adapted housing as reference, that is, of a more common typology in the area, and another one, artificially acclimatized. The index evaluated was the temperature and humidity (THI), the black globe temperature and humidity index (GTHI) and the thermal radiation charge (TRC). It was calculated from the measurement of the temperature of dry bulb, temperature of wet bulb, temperature of black globe and air speed. The measurements were made both in the intern and the extern environment, at four times (5 a.m, 11 a.m., 3 p.m. and 4 p.m. o'clock) and in two seasons (late spring and early summer), for ten days in a row. The results allow to conclude that the house naturally acclimatized (NA) has presented intermediate performance as compared with the others, making it to possible to control environment at adequate levels only during spring.

Índice fuzzy de conforto térmico para frangos de corte

A estimativa de conforto térmico na avicultura moderna é importante para que sistemas de climatização possam ser acionados no tempo correto, diminuindo perdas e aumentando rendimentos. Embora a literatura corrente apresente alguns índices de conforto térmico, que são aplicados para essa estimativa, estes são baseados apenas em condições do ambiente térmico e não consideram fatores importantes inerentes aos animais, tais como genética e capacidade de aclimatação, provendo, geralmente, uma estimativa inadequada do conforto térmico das aves. Este trabalho desenvolveu o Índice Fuzzy de Conforto Térmico (IFCT), com o intuito de estimar o conforto térmico de frangos de corte, considerando que o mecanismo usado pelas aves para perda de calor em ambientes fora da zona termoneutra é a vasodilatação periférica, que aumenta a temperatura superficial, e que pode ser usada como indicador do estado de conforto. O IFCT foi desenvolvido a partir de dois experimentos, que proporcionaram 108 cenários ambientais diferentes. Foram usadas imagens termográficas infravermelhas, para o registro dos dados de temperaturas superficiais das penas e da pele, e o grau de empenamento das aves. Para os mesmos cenários de ambiente térmico observados nos experimentos, foram comparados os resultados obtidos usando o IFCT e o Índice de Temperatura e Umidade (ITU). Os resultados validaram o IFCT para a estimativa do conforto térmico de frangos de corte, sendo específico na estimativa de condições de perigo térmico, usual em alojamentos em países de clima tropical. Essa característica é desejável em modelos que estimem o bem-estar térmico de frangos de corte, pois situações classificadas como perigo acarretam no dispêndio de recursos para evitar perdas produtivas.

Broiler Response to Different Wind Speeds

Broiler production in Brazil has turned into a very competitive activity in the late years. Constant innovation leads to higher productivity maintaining the same cost of production, which is a desirable situation. Lately one characteristic for broiler housing in Brazil has been the increase in birds density requiring the use of controlled environment through the use of fan and fogging systems in order to achieve better birds productive performance. Most Brazilian producer already uses cooling equipment however it is still unknown the right way to control the wind speed and direction towards the birds. This present research has the objective to evaluate the effect of the wind speed on the heat transfer from the birds to the environment for broilers at 27 days old. There was used 200 birds, placed in a wind tunnel measuring 1.10 m high by 1.10m wide x 10.0 m of length, and the birds density varied from 9, 16 and 20 birds/m 2. Two wind speed were simulated 340 rpm (1.0 m/s) and 250 rpm (0.3 m/s). The increase in the wind velocity related to the smaller bird densityled to a higher heat loss and to a more uniform temperature distribution in its exposed areas.

Proposição de um checklist de acompanhamento de processos construtivos habitacionais em wood-frame

The need for housing in Brazil is very large, and despite government efforts to address this issue, the housing deficit is too large. When analyzing markets without this problem, it is concluded that one of the factors that influence this model is the construction adopted by Brazilian society that is in masonry. Alternatively, the system can be used in constructive Wood-frame. To apply this system in Brazil, one can say that the workmanship and the materials available to meet the demand would be created in a short period of adjustments and capabilities, but identifies himself as one of the biggest problems the planning and management of works. And one of the tools for solving this problem is to use a checklist of the activities of constructive process, avoiding forgetting or not aware of the activities necessary to complete the project

Impactos socioespaciais do uso e ocupação do solo urbano na área de entorno do Aeroporto Internacional de São Paulo - Guarulhos - Andre Franco Montoro

The construction of the São Paulo International Airport in Guarulhos recorded significant economic growth for the whole region, especially for services and jobs generated. Despite the importance of its presence in Guarulhos, we note the absence of an articulate and committed planning to urban development of the city, mainly in adjacent areas to this airport system planning. Through this stud, we analyzed primarily the major interferences and modifications afforded by its presence in guarulhense spatiality. We found that the government was, to some extent, tolerant to mounting housing in the surrounding area to the airport, from the moment that allowed the diverse urban land use in the place where it was planned to build such equipment. We further note that the airport is developed autonomously to the municipality in which the investments and related works only aim to meet the needs of the enterprise

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces

Ambiente térmico y el bienestar de los cerdos en el período de descanso previo al sacrificio

The research aimed to evaluate the relationship between the thermal environment of the rest pens in a pig slaughterhouse and the surface temperature (ST) of the animals as well as the effect of intermittent water spraying on thermal comfort. There were two visits to slaughter industrial being in each selected three pens of rest, one for control treatment (no spray throughout the period) and two for the treatment of intermittent spraying water (30 minutes intervals with constant spray followed by 30 minutes then turned off). Assessments began at the time of discharging animals in which are taken the thermographic images from lots using an infrared thermographic camera. After housing in the pens, were registered the thermographic images and the respiratory frequency (RF) every five minutes for four hours. Were evaluated the temperature, relative humidity and temperature-humidity index (THI). Considering the values of THI was observed that the animals remained in a condition of comfort only at the time of his arrival at the slaughterhouse. The ST and RF of the animals kept in the pens without sprinkler system (control) showed a linear increase in function of time of day, with increasing temperature. The treatment with intermittent sprinkling of water was observed oscillatory behavior of the ST and RF, however it was always lower than the control treatment, even in times when the water sprinklers were turned off. The time required of spray to reduction and stabilization of the ST of the animals was limited to the combination of temperature and relative humidity, being estimated at 25 minutes at times of higher THI. The maximum environmental temperature during evaluation was 28.4 oC.
