activated sludge or extended aeration treatment involves a continous system where aerobic biological growths are mixed with waste water and then separated in a gravity clarifier. therefore, waste treatment system such as the activated sludge system depend on the activities of communities of living organism. in this study, an attempt was made on the indentification of the bacterial population in...

The need for effective methods for the detection and measurement of chemical warfare agents (CWA) has increased in recent years. Current stockpiles need to be monitored to ensure their safe containment. The remediation of sites containing abandoned CWAs requires analysis in support of safe removal and destruction of agents. More recently, counterterrorism efforts have underscored the need for m...

The association of antibody with y-globulins was first demonstrated electrophoretically in the serum of rabbits immunized with egg albumin; Tiselius & Kabat (1939) and Enders (1944) found antibodies against a wide range of virus, toxin and bacterial antigens in the y-globulin prepared from pooled human plasma by ethanol precipitation. Kekwick & Mackay (1954) used one of these antibodies, the Sa...

This analysis of thirteen cases of lower airway foreign body aspiration in children reveals a high incidence of aspiration into the left main bronchus, and an increased incidence in older children. Early indentification of nonradio opaque foreign bodies such as food and plastic toys is difficult in the absence of a positive history. Suggestions are offered for prevention, early detection, and t...

A technique is described for the routine preparation of seminal fluid specimens for transmission electron microscopy. The method is applicable to cases where examination of sperm morphology is required and can also be used for the indentification of non-spermatozoal cells and their inclusions.

The macroscopical characters of the roots, physical constant values, extractive values, colour, consistency and extractive values with different solvents, behaviour on treatment with different chemical reagents, fluorescence characters of liquid extracts and root powder after treatment with different chemical reagents under ultraviolet light of the powdered roots of Tragia involucrata Linn. (Fa...
