BACKGROUND The aim of this study was to evaluate the content of mercury (Hg), arsenic (As), nickel (Ni) and tin (Sn) in raw cow's milk of traditional and industrial sites from 8 different sites in Arak City, Markazi Province, Iran. METHODS In this cross sectional study, a total of 32 samples were collected from sub-cities of Arak, Iran via subjective sampling method. Both industrial and tradi...

in order to investigate the prevalence of infection with bovine viral diarrhoea virus(bvdv) of cattle in ahvaz,blood samples were collected from jugular vein of 572 cattle(521 female, 51 male) from industrial and nonindustrial farms. sera were stored at -20?c while waiting for analysis. the sera were tested by elisa, using a commercial elisa kit for detection of specific antibody to bovine vira...

  Background : Since milk is considered as one of the most common foods in human life, this research aimed to evaluate the quality of milk produced in traditional and industrial dairy farms of Yazd province in 2007.   Materials and Methods : In this descriptive study, six farms were selected in the cities Sadoogh, Yazd and Mehriz and sampling was performed in each of them bimonthly...

Background: BIV is a well-known bovine immunosuppressive cause, but its pathogenesis has not been well characterized. In recent years, it has been hypothesized that infection with BIV might predispose cattle to be infected by other agents. OBJECTIVE: This study was performed to investigate of BIV and Brucella co-infection so that in the future more studies will be done on the issue of predispos...

Established in 1990, the New Milford Farms (NMF) composting facility serves as a low-cost means of disposal for various industrial residues from Nestle USA, a large international food company. The NMF facility takes in organic feedstocks ranging from spent coffee grounds and industrial wastewater sludge to leaves and brush from nearby residents, and combines them to create fertilizing compost u...

Foot-and-mouth disease (FMD) is a highly contagious viral disease of ruminants, which causes fever and blisters in their mouth and feet.

Dermanyssus gallinae (Mesostigmata: Dermanyssidae), a mite of poultry, represents the most important ecotoparasite of egg-laying poultry in several countries. We estimated the prevalence of D. gallinae infestation in 38 industrial poultry farms (28 egg-laying and 10 reproductive hen farms) in the governorate of Nabeul (North-East Tunisia). Traps were placed in two locations of each farm during ...

While wind farms have no inherent storage to supply power in calm conditions, this paper demonstrates that large tidal turbine farms in channels have short-term energy storage. This storage lies in the inertia of the oscillating flow and can be used to exceed the previously published upper limit for power production by currents in a tidal channel, while simultaneously maintaining stronger curre...
