The aim of the present study was to determine various types of hemocytes, total and differential hemocyte count and to show some indices of phagocytosis, including percent phagocytosis and phagocytic index in Indian white shrimp, Fenneropenaeus indicus in Iranian shrimp farms. The hemolymph was extracted from the shrimps and mixed with anticoagulant. It then stained and Yeast was added as forei...

objective:at the present study, relationship between phagocytosis of plga particles and combined effects of particle size and surface pegylation was investigated.  materials and methods:microspheres and nanospheres (3500 nm and 700 nm) were prepared from three types of plga polymers (non-pegylated and pegylation percents of 9% and 15%). these particles were prepared by solvent evaporation metho...

hypothesis may still lbe a topic for controversy among philosophers, but among the great majority of active scientists I think it is accepted without question The workings of our minds and bodles, and of all the animate or lnanimate matter of which we have any detailed knowledges are as sumed to be controlled by the same set o£ fundamental laws which except under certain extreme conditions we f...

For a model of weakly coupled quantum Ising chains we outline the phase diagram and establish that well below the transition line the system has a remarkably one-dimensional spectrum. We study the dynamical magnetic susceptibility and find a very rich spectrum with several modes corresponding to a fundamental particle and its bound states. The approach is based on the Bethe ansatz and the rando...

Precipitative mixing experiments have been conducted with the aid of a turbidimeter and a darkfield microscope. The results of these experiments, correlated with observations of macroscopic features, indicate that serological precipitation is largely governed by a highly specific mechanism except in the terminal period, when the operation of non-specific forces becomes apparent. The findings ar...

In theoretical physics, paradoxes are good. That’s paradoxical, since a paradox appears to be a contradiction, and contradictions imply serious error. But Nature cannot realize contradictions. When our physical theories lead to paradox we must find a way out. Paradoxes focus our attention, and we think harder. When David Gross and I began the work that led to this Nobel Prize [1, 2, 3, 4], in 1...

The influence of aluminum, within the range of 0.08 - 6.16 wt.%, on the microstructure and hardness of as-cast ductile cast iron has been studied. A number of irons of different composition have been made by green sand casting and gravity die casting of appropriate design to provide the experimental materials. It has been found that Al addition and higher cooling rates in permanent mould castin...
