many cell lines, when cultured under proper conditions, can form three dimensionalstructures called multicellular spheroids. these spheroids resemble in vivo tumor models in severalaspects. therefore, studying growth characteristics and behavior of spheroids is beneficial inunderstanding the behavior of tumors under various experimental conditions. in this work, we havestudied the growth proper...

employees’ satisfaction based on their physical environment is an important factor that can improve employees’ performance, job satisfaction, and organizational productivity in office buildings. occupants’ environmental satisfaction are related to 10 different characteristics, including thermal comfort, air quality, lighting, acoustic quality, office layout, workspace furnishing, cleanliness an...

a series of polystyrene hybrid nanocomposites have been fabricated with varying amounts of tio2 viz., 0, 0.5 and 1 % w/w along with 3% ts by in-situ polymerization method. the influence of surface modified tio2 nanoparticles on the thermal properties of ps matrix was examined using thermogravimetry and differential scanning calorimetry. thermal characteristics of the polystyrene/ts/tio2 hybrid ...

in this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. an impression of grinding time on the structural and thermal properties of sr-doped lamno3 system with la1-xsrxmno3 (x=0.2) stoichiometric ratio was investigated. the nano crystallite lsm powder with cubic structure was prepared by varying the milling time of planetary monomill ...
