probiotics are live microorganisms with beneficial health effects on host animals which exert their effects on performance, gastrointestinal tract and immune system. various probiotic products are available in the market. this study compared the effects of various probiotic products on broiler performance, intestinal morphology and some immunological and hematological parameters. five probiotic...

safety performance is the overall performance of the organization safety management system in the operational system of safety. in the present study, the components of safety performance included visible management leadership, employee participation, training, inspection, implementation tools, and maintenance. the objectives of this study were to assess safety performance, and to analyze differ...

ENVISAT/ ASAR interferometry is a useful tool for the retrieval of geoand bio-physical parameters. In this paper the aim is show the quality of interferometric ENVISAT/ ASAR products. This objective will be approached in two ways. First, the timing accuracy of various ENVISAT/ ASAR products is evaluated. The geometric calibration and validation includes the determination of slant-range and azim...

The newly finished ESA project MERIS Lakes included activity in Lake Victoria to show the potensial for monitoring this eutrophic African Lake. In this study an evaluation of how different processors perform in Lake Victoria. Lack of proper validation data makes it only possible to have a preliminary assessment of the performance of the product algal_2, suspended material and the signal depth, ...

We describe validation measurements of the geometric accuracy of ASAR images, measured redundantly via independent methods. Our tests include image (IM), alternating polarisation (AP), and wide swath (WS) mode acquisitions over a variety of test sites. ASAR's slant range products (IMS/APS) require a slightly different validation methodology than ground range precision (IMP, APP) and medium reso...

Numerous Optical Character Recognition (OCR) companies claim that their products have near-perfect recognition accuracy (close to 99.9%). In practice, however, these accuracy rates are rarely achieved. Most systems break down when the input document images are highly degraded, such as scanned images of carbon-copy documents, documents printed on low-quality paper, and documents that are n-th ge...
