Transportador de correia: componentes e cálculos básicos para seu dimensionamento

Increasingly, people searches for an efficient and economic way for transporting bulk materials. Transport through belts is now the most widely used mean for transporting bulk materials, used by companies from various sectors such as mining, quarrying, agribusiness, etc. There are many advantages of using a conveyor belt as compared to rail or by truck. Trucks needs a driver, have a high risk of accidents as well as a high cost for maintenance and as well as trains, after making the downloading of the material, return empty to the next load. The cost for the construction of a railway is very high, making it often impossible. The conveyor belt have a high cost of installation, but it works 24 hours a day, 365 days a year. The upper side of the belt is always loaded, the maintenance cost is average and the risk of accidents is low, causing it to be the ideal way to transport bulk materials. This monography aims to interest the reader about what is a conveyor belt, what are its main components and demonstrate the basic calculations for their sizing and selection of components. Throughout the work, scaled a belt conveyor for use in the mining sector, but the concepts demonstrated apply to the transport of any material

Perfil de Aglutininas Anti-leptospira e anti-brucella e condições sanitárias de ovinos da região noroeste do Estado de São Paulo, Brasil

The sheep industry has become increasingly prominent in agribusiness, transforming the stage production of Brazil, and thus contributes more to the socio-economic development of the country. The work aimed to verify the occurrence of brucellosis and leptospirosis in sheep from northwestern São Paulo state. In addition to determining the prevalence of major Leptospira in the region and to trace the diagnosis of sheep breeding in this part of the country. All the 1222 sheep serum samples from 49 properties did not react serologically to evidentiary testing for brucellosis, compared to antigens of B. abortus and B. ovis used in the testing of 2-ME and IDGA, respectively. The Microscopic Agglutination Test (MAT) test revealed that 19.14% (232/1212) of samples were positive for one or more serovars, with titles ranging from 100 to 800. The most frequent serovar was hebdomadis in the region, with Sentot and Sherman (18.10%, 11.64% and 8.62%, respectively). By profiling the system of sheep farming in the region, we found that most herds are composed of more than one race being the main purpose is for the court. According to the scheme adopted immunoprophylactics there is a homogeneous set schedule. It adopts the use of anti-helminth, non-prescription veterinary antibiotic. There is also the presence of diarrhea and abortions and the lack of criteria for los ovinos on management, making it the need for emergency development of programs for disease control, schema immunoprophylactics adequate sanitation and hygienic measures in sheep breeding.

Análise Energética do processo experimental de produção de Biodiesel a partir do óleo de frango

There is a great global concern about the depletion and the high cost of fossil fuel reserves exploitation, more than ever, it is necessary to make a profound study and take advantage of alternative sources that can be used as energy efficiency with an appropriate pricing and low environmental impact. Brazil, which has highlighted using alternative energy sources as the use of ethanol and, in recent years, has been encouraging the expansion of its energy matrix in which the biodiesel will have a strategic importance within the agrobusiness area. Biodiesel is a fuel that can replace the diesel, which is a petroleum derivative. It is an ester, produced in the transesterification reaction of vegetable oils and animal greases, in an alcohol with an additional catalyst, are converted into fatty acids and result in esters with glycerol as sub products. The objective of this study was to estimate the final energy balance for the process biodiesel production from oil chicken waste. The energy balance estimation was quantified in calorific value according to the energy expenditure by calorimetric bomb method. The relationship between input and output of energy was around 0.97. In a first evaluation, the procedures adopted should be improved enough, so the process can become energetic and economically viable.

LH surge in response to the treatment with GnRH analog or estradiol in ovariectomized buffaloes with or without progesterone pre-exposition

The aim of the present study was to evaluate the LH surge after EB (estradiol benzoate) or GnRH administration with or without P4 (progesterone) pre-exposure in ovariectomized (OVX) buffalo cows. Females were randomly assigned to receive an intravaginal P4 device (D0–D9). They were then given EB 24 h or GnRH 36 h post-P4 device removal (factorial 2×2, n=6 per group). Blood collection for LH measurement began 36 h after the P4 device removal and continued at 3 h intervals. The area under the LH curve (AUC; 30.2 ng2 and 13.41 ng2; P=0.007) and the area of the LH peak (AP; 19.0 ng2 and 8.9 ng2; P=0.009) were greater for EB than GnRH. We did not observe an effect of P4 pre-exposure on the AUC and AP. Furthermore, there was no interaction between P4 pre-exposure and EB or GnRH treatment on the AUC and AP. However, there was an interaction (P<0.01) between P4 pre-exposure and the type of inducer (EB or GnRH) to release a preovulatory-like LH surge at the beginning (BP), final (FP) and time (TP) of the LH peak. The P4 pre-exposure anticipated the BP (2.5 and 7.4 h), TP (6.0 and 12.0 h) and FP (11.5 and 17.1 h) when EB was used to induce a preovulatory-like LH surge (P<0.01). However, there was no effect of P4 pre-exposure on BP (0.4 and 0.4 h), TP (3.0 and 3.0 h) and FP (5.9 and 6.1 h) with GnRH treatment. There was also no effect of the pre-exposure to P4, type of inducer or interaction on the amplitude of the LH peak. We concluded that EB therefore led to greater LH release than GnRH, and pre-exposure to P4 before EB administration anticipated the preovulatory-like LH surge in buffalo cows.
