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...
a study of the atmospheric particulate size distribution of total suspended particulate matter(tspm) and associated heavy metals concentrations has been carried out for the urban part of sarajevo city,bosnia and herzegovina. urban particles (n=150) were collected using a high volume air sampler equippedwith a 6-stage impactor. apart from fe which has been determined by flame atomic absorption s...

Tetrathiatriarylmethyl radicals are attractive spin probes extensively used in biomedical magnetic resonance applications. We report a straightforward synthesis of two original tetrathiatriarylmethyl radicals incorporating, respectively, 15 and 45 fluorine atoms, and thus possessing a high affinity to fluorous media. F15T-03 and F45T-03 exhibit a single sharp EPR spectrum and their EPR line bro...
Loess grain size data used to infer transport direction or wind strength are generally derived from vigorously disaggregated samples. However, these data may not adequately represent the effective particle size distribution during loess transport, if the transported dust contained aggregates of finegrained material. Thin sections of minimally altered C and BC horizons in the late Pleistocene Pe...
Introduction Conclusions References
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
tricalcium phosphate as hydroxyapatite is used as a suspension stabilizer in styrene polymerization process. particle size of tcp plays an essential role in the particles’ size distribution and geometrical form of polystyrene products. as the particle size of tcp is reduced, there will be much better chance to engulf the styrene particles. the higher the number of tcp particles surrounding each...
A problem of all particle methods is that they produce large vacuum regions when they are applied to a free gas ow, for example. With the approach recently proposed by the author Numer. Math., in press], this diiculty can be avoided. One can let the particles adapt their size to the local state of the uid. How, is described in the present article. The diameter as an additional degree of freedom...
