A simplified method is used to determine the optimum water content in the flue gases of charcoal gasifiers to be utilized as alternative fuels in the operation of engines and gas turbines for power generation. Computational models of plug flow reactors and well stirred reactors are employed to simulate the reaction and post-flame zones, adopting different chemical mechanisms. In the simulations...
Detailed three-dimensional neutronics analysis has been performed for ITER with the U.S. solid breeder blanket utilizing sintered product materials for both the breeder and multiplier. The overall tritium breeding ratio is 0.81 with two outboard breeder zones and 0.89 for the three outboard breeder zone design option. The total reactor thermal power is 1150 MW in the technology phase.
In a mouse model of thermal injury, an increase in burn size produced a decrease in the ratio of Candida albicans cells adherent to the marginal zone to those adherent to the white pulp of the spleen, an increase in the number of Candida cells in the circulation and in the kidneys, and an increase in mortality.
Existing thermal comfort field studies are mainly focused on the relationship between the indoor physical environment and the thermal comfort. In numerous chamber experiments, physiological parameters were adopted to assess thermal comfort, but the experiments' conclusions may not represent a realistic thermal environment due to the highly controlled thermal environment and few occupants. This ...
رسوبات کرتاسه بالایی در پهنه ایران زمین در حوضه های متفاوت، با توجه به شرایط حاکم در زمان تشکیل، ظاهراً یکنواخت نبوده است. در نتیجه، واحدهای سنگ چینه ای رسوبات کرتاسه بالایی ایران، به استثناء زاگرس و کپه داغ نامگذاری نشده یا دارای نام های محلی هستند. جهت مطالعه رسوبات کرتاسه بالایی در البرز شمالی برشی در حوالی منطقه پل زغال انتخاب گردید. برش انتخاب شده، در 21 کیلومتری جنوب چالوس به صورت ترانشه آ...
Background and aims: One of the innovative technologies for air pollution control is non-thermal plasma. The dielectric barrier discharge reactor is one of the reactors that applied in non thermal plasma technology for air polluation control. In dielectric barrier discharge reactor, the distance between the electrodes for electric discharge is low and led to increasing space velocity of the pol...
The charge-density-wave transition in TiSe (2), which results in a commensurate (2x2x2) superlattice at temperatures below approximately 200 K, presumably involves softening of a zone-boundary phonon mode. For the first time, this phonon-softening behavior has been examined over a wide temperature range by synchrotron x-ray thermal diffuse scattering.
Minimal models are developed to examine the origin of large negative thermal expansion in underconstrained systems. The dynamics of these models reveals how underconstraint can organize a thermodynamically extensive manifold of low-energy modes which not only drives negative thermal expansion but extends across the Brillioun zone. Mixing of twist and translation in the eigenvectors of these mod...
