biosorption of two anionic dyes, eosin y and eosin b, from aqueous solution using saccharomyces cerevisiae was investigated in a batch mode. the influence process parameters such as contact time, initial dye concentration, sorbent dosage, ph and temperature of aqueous solution were studied. the maximum adsorption capacities were found to be at 200 and 100 mg g-1 for eosin y and 1 eosin b, respe...

fresh semen obtained from infertile men occasionally exhibits the total absence of motile sperm (100%asthenozoospermia). vitality tests may reveal that a proportion of the immotile sperm has functional membranes, which are considered viable. an easy test for the prior determination of sperm viability may assist in sperm selection for the microinjection of oocytes. the main objective of this stu...

Additional experimental work on the subject of eosin hemolysis has been carried out. This indicates that red cells may be protected against the toxic action of eosin in sunlight by the presence of inorganic reducing agents. It is pointed out that a marked parallelism exists between the substances which react with the Folin and Denis reagent and the compounds which afford protection to red cells...
