Evolutionary changes in the seasonal timing of life-history events can alter a population's exposure to seasonally variable environmental factors. We illustrate this principle in Wyeomyia smithii by showing that: (1) geographic divergence in diapause timing reduces differences among populations in the thermal habitat experienced by nondiapause stages; and (2) the thermal habitat of the growing ...

dezful embayment contains several potential source rocks deposited in tectonically active environments. existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the middle east. the pabdeh formation (lower paleocene-eocene), the gurpi formation (santonian-masstrichtian), the kazhdumi formation (albian) and the gadvan formation ...

the effects of magnesium hydroxide and l-lactide dimer as additives on thermal properties and morphology of poly(l-lactide) (plla) films were studied. hence, neat plla films and films containing additives (10% w/w) were prepared in dichloromethane at room temperature via solution casting. to evaluate thermal history on polymer properties, plla films were annealed by different processes. in one ...

The large blood vessels would act as a heat sink and hence plays a significant role during photo-thermal therapy. Gold nanoshell was considered as an high heat absorbing agent in photo-thermal heating to reduce the cooling effect of large blood vessels. In this paper, the thermal history of tissue embedded with large blood vessels during photo-thermal heating were calculated using finite elemen...
