Última Converting a Conventional Vehicle into an Electric Vehicle (EV) BABT Silva,Jardel Eugenio da; Urbanetz Junior,Jair. Abstract The electric vehicle (EV) is not a recent invention. Between the end of the XIX century and the beginning of the XX century, most motor vehicles were electric, due to their superior reliability and cleanliness, compared to that of vehicles driven by internal combustion engines (ICE). However, with the development of ICEs and the reduction of their price, electric cars were forgotten. Only almost a century later, they returned in the market due to a significant increase in fossil fuels prices, as well as to a growing environmental concern. EVs present a number of advantages over ICE vehicles: they are simpler and require less use and replacement of parts, resulting in lower maintenance costs; moreover, they do not release pollutants into the...

Ciênc. Avic. Pereira,DF; Vitorasso,G; Oliveira,SC; Kakimoto,SK; Togashi,CK; Soares,NM. Heat stress limits the productivity of laying hens, as reflected by egg production and egg quality. The present study aimed at showing the correlations between egg quality parameters and environmental variables recorded on the day eggs were laid and on the previous days. Birds were housed in battery cages in a commercial poultry house. Main component analyses were used to verify associations between environmental and production variables, and Pearson's linear correlation tests were used to further investigate those associations. Analyses were carried out separately for to layer strains, Dekalb® White and Hy-Line® w36, and the variables egg weight (g), eggshell weight (g), specific gravity (g/cm³) and eggshell percentage (%) were compared with the...

Policy makers and policy analysts are frequently faced with situations where it is unclear whether market-based instruments hold real promise of reducing costs, relative to conventional command-and-control approaches. We develop rules-of-thumb that can be employed with minimal amounts of information to estimate the potential cost savings associated with marketbased policies, with an application to the environmental policy realm. Our hope is that these simple formulae can aid policy analysts and policy makers in the early stages of exploring alternative policy instruments by helping them identify approaches that merit greater attention and more detailed analysis. We illustrate the use of the rules-of-thumb with an application to nitrogen oxides control in...

Ano: 2000 URL: http://purl.umn.edu/10577 Could a diet enriched with n-3 highly unsaturated fatty acids be considered a promising way to enhance the immune defences and the resistance of Penaeid prawns to environmental stress? ArchiMer Chim, Liet; Lemaire, Pierrette; Delaporte, Maryse; Le Moullac, Gilles; Galois, Robert; Martin, Jean-louis. The prawn Penaeus stylirostris (Stimpson), when fed for 28 days with n-3 highly unsaturated fatty acid (HUFA)-enriched feed pellets, demonstrated an enhanced resistance to variations in environmental parameters (a decrease in temperature and salinity over a 4-day period from 28 degreesC to 17 degreesC and from 35 parts per thousand to 10 parts per thousand respectively) and an improvement in their immune defence potential, i.e. increased agglutination titre of plasma and increased respiratory burst of haemocytes.

The considerable difficulties associated with cross-border environmental management are compounded when polluters are unlicensed micro-enterprises such as auto repair shops and traditional brick kilns; such "informal sector" firms are virtually impossible to regulate in the conventional manner. This paper describes an example of an innovative and promising approach to the problem: the Cd. Juarez Brickmakers' Project, a private-sector-led, binational initiative aimed at abating highly polluting emissions from Cd. Juarez's approximately 350 informal brick kilns. We draw three lessons from the Project's history. First, private-sector-led cross-border initiatives can work -- indeed they may be more effective than public sector initiatives -- but they require...

Commodity payments in Europe and North America are production based, encouraging greater chemical use and cropping area. Thus, each region undermines the other’s price supports at the expense of the environment. Countries can, however, sever the link between yield levels and payments. Allowing farmers to exit agriculture poses challenges for the US, but perhaps not for Canada and the EU.

ABSTRACT: Seventeen outbreaks of dermatophilosis are reported from three farms affecting Santa Inês and Santa Inês x Dorper sheep that were reared in irrigated areas with rotational grazing at a stocking rate of 50 to 100 sheep per hectare, in the Brazilian semiarid region. Most outbreaks occurred after rains and affected sheep of different ages, with morbidity rates of 0.77% to 31%. Clinical signs were dermatitis with crusts that stood out easily and left areas of alopecia. Dermatophilus congolensis was isolated in cultures in 5% sheep blood agar by means of Haalstra’s method. Histologically, the epidermis showed extensive multifocal areas of ortho and parakeratotic hyperkeratosis with intracorneal microabscesses and presence of D. congolensis. Sheep...

Em decorrência do contínuo crescimento da avicultura no Brasil, tanto de corte quanto de postura, ocorre concomitantemente um aumento de alojamento de matrizes e, portanto, dos resíduos formados pela incubação de ovos férteis. Em contrapartida no Estado de São Paulo criou-se, recentemente, a Lei no 12.300, de 16 de março de 2006, obrigando os incubatórios a dar um destino adequado aos seus resíduos. Devido ao custo de manejo dos resíduos, tem-se a oportunidade de se estudar novas alternativas, que possam eventualmente agregar valor ao produto, possibilitando sua comercialização. Objetivou-se neste estudo analisar quais os destinos dados aos resíduos de incubatórios no Estado de São Paulo. Um grupo de cinco empresas representativas foi entrevistado....

Wastes from the seafood industry can be easily processed into products with new forms of use. The present study was aimed at determining the chemical composition and functional properties of shrimp waste protein concentrate and lyophilized flour. The raw material used in this study consisted of waste (head) of Litopenaeus vannamei. The protein concentrate was obtained by ethanolic extraction, being subsequently submitted to drying in oven at 70° C, while the flour was obtained by lyophilization of shrimp wastes. Moisture, ash, protein and calcium contents showed significant difference between fresh shrimp head waste samples (IN) and protein concentrate and lyophilized flour samples.

ArchiMer Dormoy, Jean-marc. Based on a four years survey of Pacific Oyster Crassostrea gigas growth in the main shellfish farming areas of Brittany from 1989 to 1992, this report is a first attempt to explain the differences between sites and years. The determinist growth models do not suit to this objective, for methodological and practical reasons. Nevertheless, they provide the conceptual basis of a global model by identifying the reliable environmental parameters for a statistical explanation of growth results. The present study proposes a methodology for a global statistical model using the main stages of the ecological and biological processes of shellfish growth. These propositions are based on the analysis of the determinist model's constraints, and also on the identification...

Avic. Gigli,ACS; Baracho,MS; Nääs,IA; Silva,RA; Zago,R; Dall'Anese,FP. Intensive broiler production in tropical climates requires adequate air circulation to control heat stress. Excess of air speed may lead to dust production and reduction of air quality and, consequently, production parameters. Brazilian regulations prohibit the presence of pathogens that may deteriorate air quality, and the presence of fungi in the air inside the poultry houses is limited to 750CFU/m³. The aim of this study was to evaluate the presence of fungi in two distinct types of broiler houses. The research compared two types of air ventilation: conventional (G1) and positive tunnel ventilation (G2). The fungi were collected using a dust sampling pump, with the air flow calibrated to 1.5 L/min. The filter impregnated with dust was submitted to...

Ano: 2004 URL: http://purl.umn.edu/28728 Do Lower Prices For Polluting Goods Make Environmental Externalities Worse? AgEcon Brennan, Timothy J.. Lower prices for polluting goods will increase their sales and the pollution that results from their production or use. Conventional intuition suggests that this relationship implies a greater need for environmental policy when prices of "dirty" goods fall. But the economic inefficiency resulting overproduction of polluting goods may fall, not rise, as the cost of producing those goods falls. While lower costs exacerbate overproduction, they also reduce the difference between private benefit and the total social cost--the sum of private and external costs--associated with that overproduction. We derive a test, based on readily observed or estimated parameters for conditions in which the latter effect outweighs the former. In such cases, making a dirty good...

Understanding the respective roles played by donor and recipient pearl oysters in pearl quality determination in relation to the environment is a challenge for the pearl industry. In most Pinctada species, pearl size is mainly related to recipient oyster growth performance, but also relies to some extent on the biomineralisation activity of the pearl sac, a tissue that originates from the donor oyster mantle. We examined donor effect on pearl size in response to culture in the lagoons on Arutua and Apataki atolls. Overall nacre weight and thickness were greater in Arutua than in Apataki, but sensitivity to the environment differed between donors. Some donors were associated with significantly heavier and thicker nacre in Arutua (I group), while others had...
