Gums were precipitated from solutions gL,Tail End Syrup and Affination Syrup6sing.acidified alcohol. The precipitated solution was centrifuged and the gums washed by successive mixing, centrifuging and decanting with alcohol. The washed gums were dissolved in hot water and reprecipitated with acidified alcohol. After further washing the gums were re-dissolved. The gums and starch content of the...

Many elderly people in both developing and developed countries are institutionalized--often irrespective of whether their ability to function requires it. Increased attention is now being given to prospects for decanting geriatric institutions and planning new forms of care. However, methodologic difficulties exist, it being hard to determine how much of the institutionalized elderly population...

The extraction of nematodes from clay soil is difficult using flotation-sieving methods of soil-water suspensions. Aggregated soil particles trap nematodes and prevent them from passing through the top coarse sieves during decanting. Also, the soil aggregates clog the sieves which slows the decanting operation. In addition, clay particles are difficult to clean from centrifuge tubes that are us...

Abstract Analyses and aggregations of the ratings that wine critics judges assign to wines are made difficult by stochastic error biases remain even when assessed blind price, label, capsule, closure. Stochastic is due partially random nature ratings. Cognitive omitted-variable anchoring, expectation, serial position, commercial, other factors. Differences in decanting, filtering, aeration, tem...

INTRODUCTION Several studies have shown that exposure to antineoplastic drugs can cause reproductive toxic effects as well as carcinogenic effects. Presence of these drugs in the urine of hospital personnel has been widely studied and some work has been done on exposure by inhalation. So far, assessment of dermal exposure to antineoplastic drugs has not been extensively studied. In this pilot s...

BACKGROUND Approximately 300 pesticide retailers are currently registered in Tanzania. Inadequate knowledge and unsafe handling practices among retailers may contribute to human pesticide exposure and environmental contamination. This study investigated pesticide retailers' qualifications, work experience, safety practices and the products distributed so as to identify opportunities for prevent...

Introduction Laboratories often modify procedures recommended by the European Urinalysis Guidelines for urine sediment analysis. The aim of this study was to compare the recommended protocol with our routine laboratory procedure and to evaluate the possible impact of modifications in the relative centrifugal force, type of tube, method of supernatant aspiration and urine volume on patient's res...
