conclusions the excellent antimicrobial activities of the tested eos might be due to their major phenolic or alcoholic monoterpenes with known antimicrobial activities. hence, these eos can be possibly used as an antimicrobial agent in treatment and control of oral pathogens. results the tested eos inhibited the growth of examined oral pathogens at concentrations of 0.015-16 µl/ml. among the ex...
in this study, residual amount of pentachlorophenol (pcp) as the most important paper preservative, which is extremely hazardous pollutant, was determined in some tissue papers and napkins. twenty-five samples of two producing hygienic paper factories prepared from virgin and secondary pulp were analyzed for the presence of trace amount of pcp. the analytical procedure involved direct extractio...
to test whether they would remove experimentally infested pupae following methods of Boecking and Drescher (1992). In 1994, the hygienic colonies removed significantly more pupae infested with one mite per cell than the non-hygienic colonies. In 1995, there was no significant difference between the hygienic and non-hygienic colonies when one or two mites were introduced per pupa due to variatio...
Hygienic behaviour, an intranidal task performed by middle-aged worker bees is an important behavioural mechanism of resistance to disease and to attack by Varroa destructor, an ectoparasitic mite.

In this tutorial we investigate hygienic quasiquotation in Scheme and in languages influen...
