In 1955, the first nuclear medicine division was established in Thailand by Professor Romsai Suwannik in the Department of Radiology, Siriraj Hospil, Mahidol University in Bangkok. In 1959 four years later, the second nuclear medicine division was established in the Department of Radiology, Chulalongkorn Hospital in Bangkok. The third nuclear medicine division was started in Rajvithi Hospital i...

The emergence of nuclear weapons as a new actor in international relations has introduced a new area in the international security arena. Since the appearance of these weapons, there have been increasing efforts to limit and destroy them in order to achieve global peace in the framework of disarmament and centered around the Treaty on the Non-Proliferation of Nuclear Weapons. Along with the eme...

During mitosis, the nuclear envelope merges with the endoplasmic reticulum (ER), and nuclear pore complexes are disassembled. In a current model for reassembly after mitosis, the nuclear envelope forms by a reshaping of ER tubules. For the assembly of pores, two major models have been proposed. In the insertion model, nuclear pore complexes are embedded in the nuclear envelope after their forma...

adsorption of co2 on the surface of single-wall zigzag (5,0) and armchair (4,4) carbon nanotubes (swcnts) were studied through using density functional theory (dft) calculations. optimizations of geometric were performed at the b3pw91 level of 6-311++g** method standard basis set using gaussian 03 package of program [1]. structural models were optimized and adsorption energies, band gap, charge...

Gluon distributions in the carbon and tin nuclei are investigated by using a Q 2 rescaling model with parton recombination effects. We obtain strong shadowings in the small x region due to the recombinations. The ratio G A (x)/G N (x) in the medium x region is typically 0.9 for medium size nuclei. At large x, the ratio becomes large due to gluon fusions from different nucleons. Comparisons with...

A great many observables seen in intermediate energy heavy ion collisions can be explained on the basis of statistical equilibrium. Calculations based on statistical equilibrium can be implemented in microcanonical ensemble (energy and number of particles in the system are kept fixed), canonical ensemble (temperature and number of particles are kept fixed) or grand canonical ensemble (fixed tem...
