3D Isodoselines innovation with Interior Optimization (IO) for prostate tumor BED model hyperfractionated Treatment Planning (TPO) application is further demonstrated. The implemented data was got additional-dual constrained evolutionary algorithm BED-LQ (Biological Effective Dose) in this cancer type. Results TPO IO-Graphical show a number of surfactal IO proven accuracy-feasibility the novelt...
A hydrodynamic model of a dual fluidized bed gasifier (DFBG) is developed and its predictions are compared with measurements solids flux pressure profiles from cold flow (CFM). Then, the performance DFBG theoretically analyzed in terms circulation distribution under changes riser loop seal aeration, inventory particle size, sensitivity analysis made to delimit prediction capability. Furthermore...
Hydrogen spillover over macroscopic distances was demonstrated and exploited in the design of two novel catalytic reactors for 1-butene isomerization. A dual-bed reactor containing separate zones of noble metal and bimetallic catalysts yielded activities up to 2.7 times greater than that of the noble metal alone. The noble metal catalyst contained palladium supported on graphitic carbon. The bi...
Bed rest is a recognized model for muscle atrophy and bone loss in space flight and in clinical medicine. We hypothesized that whole body vibration in combination with resistive exercise (RVE) would be an effective countermeasure. Twenty healthy male volunteers underwent horizontal bed rest for 56 days and were randomly assigned either to a group that performed RVE 11 times per week or to a gro...
Short (<10 days) periods of muscle disuse, often necessary for recovery from illness or injury, lead to various negative health consequences. The current study investigated mechanisms underlying disuse-induced insulin resistance, taking into account muscle atrophy. Ten healthy, young males (age: 23 ± 1 years; BMI: 23.0 ± 0.9 kg · m(-2)) were subjected to 1 week of strict bed rest. Prior to and ...
در دهه اخیر، ساختار فراماده الکترومغناطیسی توجه زیادی را در فیزیک و جوامع مهندسی به خود جلب کرده است. فراماده ساختاری است الکترومغناطیسی با خصوصیات همگن ومصنوعی که دارای خواص غیر عادی می¬باشد. این ساختارضریب گذردهی الکتریکی منفی و ضریب نفوذپذیری مغناطیسی منفی دارد و تحت عنوان ساختار چپگرد شناخته می¬شود. ابعاد سلولی آنها از طول موج کوچکتر است. این ساختار در طبیعت یافت نمی شوند. انتشار امواج در ا...
we introduce the notions of t-dual rickart and strongly t-dual rickart modules. we provide several characterizations and investigate properties of each of these concepts. it is shown that every free (resp. finitely generated free) $r$-module is t-dual rickart if and only if $overline{z}^2(r)$ is a direct summand of $r$ and end$(overline{z}^2(r))$ is a semisimple (resp. regular) ring. it is sho...
