this guide to the identification of iranian freshwater snails has been prepared with aim of helping individuals involved in field work, but who have had no specialized training in taxonomy to differentiate snail specimens which they collect to certain groups by means of simple identification key. the guide pays special attention to the principal snail groups which transmit human schistosomiasis...

piezodorus guildinii (hemiptera: pentatomidae) is an important soybean pest, and one of its main natural enemies is telenomus podisi (hymenoptera: platygastridae). rearing of the parasitoid is constrained by the hosts' egg quality, which deteriorates after few generations in laboratory, therefore, cold-stored host eggs utilization could be a useful tool for augmentative biological control. thus...

background opportunistic infections have become much more considerable in the last decades, especially in immunocompromised patients and due to the medical interventions. cryptosporidium is a pathogenic protozoan parasite causing diarrhea in children and some times acts as a life threatening opportunistic pathogen in the immunocompromised adults. objectives this study aimed to investigate the p...

This memo updates that of 27 August 1971, TENEX memo number 113, with regard to the finite state machine. Other parts of that memo have been incorporated into the JSYS manual and other documents.

chlorite flakes, as a product of alteration of biotite, the dominant ferromagnesian mineral in the paleozoic granitic rocks of the canadian appalachians, have been analyzed by electron microprobe for major elements and by 57fe m?ssbauer spectroscopy for the coordination and oxidation state of fe. comparison of m?ssbauer fe3+/fe ratios obtained from chlorite and its host biotite indicates that c...
