INTRODUCTION MUCH progress has been made in the last ten or fifteen years, chiefly by medical biochemists working on problems of clinical interest, in improving the accuracy and sensitivity of the methods employed for the estimation of the principal inorganic constituents of blood and other mammalian body fluids. If, however, attempts are made to apply directly these methods to the micro-analys...

1. Mitochondria were isolated from developing endosperm of Ricinus communis and were fractionated into outer membrane and inner membrane. The relative purity of the two membrane fractions was determined by marker enzymes. The fractions were also examined by negative-stain electron microscopy. 2. Membrane fractions were sequentially extracted in the following way. (a) Suspension in 0.5M-potassiu...

Groundwater, which is present in aquifers beneath the Earth's surface and used for drinking purposes throughout Jhang City, a crucial resource. The quality of water impacted by groundwater contamination one way or another, ultimately harms human health. current study aims to evaluate near culvert drainage Punjab. With aid standardized method APHA 23rd edition, samples that were collected from 9...

The flotation recovery of sphalerite depends on the inorganic reagents concentrations in liquid phase suspension and pH. This paper presents results studies interactions iron (II) containing ions with surface water solutions at different pH levels. thermodynamic electrochemical were carried out to analyze possible sulfate a environment relate them potassium butyl xanthate sodium dibutyl dithiop...
