OBJECTIVE To determine the feasibility, accuracy and cost of developing a system of on-site screening for anaemia in pregnancy in primary care clinics. SETTING Mobile clinic team in Hlabisa health district, KwaZulu-Natal. METHODS Four hundred and forty-nine consecutive women attending antenatal clinics were screened for anaemia (haemoglobin < 10 g/dl) using copper sulphate solution; the res...

This study was carried out to determine the toxicity of copper sulphate to African Catfish (Clarias gariepinus). The range – finding test was conducted twice in order to get reliable values that could be used for the definitive test. The toxicant (copper sulphate) was introduced at varying concentrations of 10g/l, 20g/l, 30g/l and 40g/l in the first rangefinding test, while it was introduced at...

An electrochemical cell consisting of two copper electrodes and copper sulphate solutions is modeled. The presented model takes into account both electrode interfaces and the activity of copper(II) ions. The current-potential equation is derived and a method for identifying mass-transfer parameters as well as kinetic parameters is proposed for a specific case. The created model is simulated and...

The Zn-Cu battery is plagued with both the problems of Cu2+ migration into the anodic chamber as well as the problem of shape change of zinc electrodes, where both of these processes together have historically prevented this type of battery technology from being rechargeable. We herein propose using a monovalent selective cation exchange membrane (CIEM) that through X-ray diffraction experiment...

Pollution represents one of the main causes inducing modifications of the structures and physical functions of the aquatic ecosystems. The toxic substances harmful action works upon the living material, first at the individual level, and then, like a chain reaction, at the other levels: species and biocoenosis. The toxicity of a chemical substance varies very much from a species to another and ...

Wilson’s disease (WD) is an inherited autosomal recessive disorder that lead to copper accumulation in the liver, brain, cornea, and other organs [1]. WD is treatable by life-long decoppering therapy with the aim of removing excess copper and preventing re-accumulation. This is accomplished with two main groups of drugs: chelating agents, including d-penicillamine (DPA) and trientine, that prom...

Article history: Received on: 08/06/2013 Revised on: 29/06/2013 Accepted on: 15/07/2013 Available online: 31/07/2013 The aim of this study is to evaluate the effects of magnesium and copper sulphates on blood glucose and serum electrolytes levels in fructose-induced diabetic Wistar rats. Diabetes was induced by administration of 20% (20g/100ml) of fructose dissolved in distilled water and admin...

In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paperusing a dip coating process. First, chitosan-copper nanoparticles solution was prepared byreduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrateas precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepareChitosan-copper nanoparticles solut...
