BACKGROUND Nano-particles are extensively employed in most industries. Several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. However, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. OBJECTIVE Investigation of the effects of silver nano-part...

BACKGROUND Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were applied on PM10 particle data in order to: identify particle clusters that can be differentiated on the bases of their chemical composition and morphology, investigate the relationship among the chemical and morphological parameters and evaluate differences among the sampling sites. PM10 was collected in ...

The paper considers a new approach to approximation expressions for integral sections of interaction and coefficients included in cascade-probability functions (CPF), spectra primary knocked-on atoms (PNA) the concentration radiation defects materials irradiated with charged particles, namely electrons, protons, alpha particles ions. obtained approximations made it possible design mathematical ...

a facile and simple method was proposed to control the size and shape of the mgo nano structures with high surface area in the presence of efficient and cheap templates like peg 200, peg 600, peg 4000 and sorbitol at low temperature within a little time. nano rods and nanoparticles have been achieved by applying these templates and altering other growth parameters. the products were characteriz...

We consider the dynamics of diffusing particles in one space dimension with annihilation on collision and nucleation (creation of particles) with constant probability per unit time and length. The cases of nucleation of single particles and nucleation in pairs are considered. A new method of analysis permits exact calculation of the steady state density and its time evolution in terms of the th...

We study a model 1-D system which describes two quasi-particles interacting with a nonlinear lattice. The quasi-particles are treated quantum mechanically, whereas the lattice is treated classically. For a range of model parameters, we find pairing between the two quasi-particles. We investigate the dynamical stability of such pairs, and comment on the possible applications to models of HTSC. T...
