abstract in respect to nano-technological studies and physiological and biochemical lesions of these materials on aquatic animals, in this study we examine the toxicity effects of nano-zinc oxide (zno nps) on hematological indices of common carp (cyprinus carpio). lc50 of nano zinc oxide was determined according to the mortality at 24, 48, 72 and 96 hours, respectively. during separate experime...

the beet moth, scrobipalpa ocellatella is recognized as a widespread agricultural pest. cold hardiness strategy of the beet moth larvae was investigated through monitoring seasonal changes at supercooling points and lower lethal temperatures. furthermore, the role of microhabitat in winter survival was studied. the mean scps of the last instar larvae was not significantly different from novembe...

background: since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. the aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of mercuric chloride (hgcl2), lead chloride (pbcl2) and zinc sulfate (znso4) pollutan...

How does it work and what is it for? Two explanations have been offered. Yarrow et al. hypothesized that it serves to create perceptual continuity across saccadic eye movements during which visual sensitivity is largely reduced, mainly due to saccadic suppression. Rose’s and Summers’ demonstration of chronostasis without eye movements, however, raises a question about this. The time perception ...

Thirty-two patients died of pancreatitis and its complications over a 10-year period. Infection (bacteremia, fungemia, or pancreatic abscess) was the major cause of death in 80%. In the remaining 20%, refractory hypotension or respiratory failure were the lethal mechanisms. In only 78% of patients was the correct diagnosis made before death. Ninety-four percent of those who died did so during t...

at Columbia University, and sitting with him for hours in the dark room harvesting plants for measuring light responses and discussing World Cup soccer and pro tennis. What are your views on scientific journals and publishing? When it comes to scientific journals, I am essentially a romantic. I love old, venerable society journals such as Genetics or other classics, they somehow breathe history...
