Based on the formalism of thermo-field dynamics a new approach for studying collective excitations in hot finite Fermi systems is presented. Two approximations going beyond the thermal RPA namely renormalized thermal RPA and thermal second RPA are formulated.

Thermal mass is the material's ability to store heat and release it after an amount of time and concrete is considered one of the best thermal mass material. Since concrete has been used widely in many building constructions, by considering the capability of concrete in terms of thermal mass, it is worthwhile to use this ability of concrete in order to build buildings more healthy and comfortab...

Background: Irreversible electroporation (IRE) is a novel tumor ablation technique. IRE is associated with high electrical fields and is often reported in conjunction with thermal damage caused by Joule heating. For good response to surgery it is crucial to produce minimum thermal damage in both tumoral and healthy tissues named Non-Thermal Irreversible Electroporation(NTIRE). Non-thermal irrev...

tio2 nanorods are synthesized by a thermal corrosion. in present work, synthesis of tio2 nanorods in anatase, rutile and ti8o15 phases, by using the sol-gel method and alkaline corrosion are reported. the morphologies and crystal structures of tio2 nanorods are characterized by use of field emission scanning electron microscopy, atomic force microscopy and x-ray diffractometer techniques. the o...
