one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
We present CCD broad band photometric observations in the fields of the Third Galactic Quadrant open clusters NGC 2580 and NGC 2588 (V (I)C and UBV (RI)C respectively). From the analysis of our data we found that NGC 2580 is located at a distance of about 4 kpc and its age is close to 160 Myr. As for NGC 2588, it is placed at about 5 kpc from the Sun and is 450 Myr old. This means that NGC 2588...
The effects of herd size, semen type, generation overlapping and breeding goal on genetic gain in Holstein cows were studied through stochastic simulation. Three levels of herd size (100, 200, and 400), two levels of semen type (unsexed and sexed), three levels of generation overlapping (low, average and high) and two levels of breeding goal (narrow and broad) were combined together to make 36 ...
