The application and efficacy of cleaning and disinfection methods are reviewed, together with the relevant European and French legislation. European Commission Hygiene Directive 93/43/EEC of 14 June 1993 proposes the adoption of hazard analysis and critical control points (HACCP) for the meat industry, and this includes cleaning and disinfection. It is necessary to organise a team for washing, ...

human interferons (ifns) are key cytokines secreted by immune system. they have several effects such as antiviral and anti tumors activity, activating immune cells and healing of multiple sclerosis. the type ifns present in humans are α, β and υ. ifn β is a polypeptide, normally produced by fibroblasts and seems to be more species-specific than ifn . structural properties of i fns are importan...

two capillary zone electrophoresis (cze) methods were developed in this study, one using an acidic buffer (sodium citrate ph = 2.5) and the other using a basic buffer (sodium tetraborate ph = 9.8). the two methods were compared on the basis of repeatability and reproducibility of results and the cze method developed with the basic buffer was then selected for further studies. the method was ful...

one of the problems encountered in ce separations of basic compounds is the adsorption of analytes onto the negatively charged capillary wall which could lead to poor repeatability of migration time and peak area. additionally, separation of enantiomers of chiral of basic drugs is commonly carried out in low ph buffer which contributes to strong ionic interaction of the cationic drug ions with ...

background and objectives: fine needle aspiration cytology (fnac) is an established out- patient procedure used in primary diagnosis of palpable thyroid lesions. a modified technique fine needle capillary sampling (fncs) obviates the need of suction, is less painful, patient friendly and reported to overcome the problem of inadequate and bloody specimens. the aim of our study was to compare the...

introduction: lobular capillary hemangioma (lch) is a benign lesion of vascular origin. it rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis. case report: in this report we present a case of lch of the nasal cavity which occurred approximately one month after delivery. there was no recurrence after complete endoscopic resection during one ...

The caries-preventive benefits of fluoride are generally accepted by dental researchers and practicing professionals worldwide. The benefits of fluoride toothpastes and mouthrinses have been supported by several high-quality systematic reviews. The formulation of a fluoride toothpaste and biological (salivary flow rate) and behavioral factors (brushing frequency, brushing time, post-brushing ri...

This paper presents the results of an experimental study on capillary tubes commonly used as expansion device in household refrigerators and freezers. The experiments were performed with HFC-134a at different condensing pressures and level of subcooling. The pressure and temperature profiles along the capillary tubes were measured in each test run. The data set was then used to evaluate the sui...

A method has been developed to infer the wettability of steam-water-rock systems based on the relationship between permeability and capillary pressure by Purcell. The Purcell model was extended to two-phase flow to verify whether the wettability is a function of water saturation. The results calculated using the experimental data showed that the wettability index in the drainage process was gre...
