Stream segregation is the process by which the auditory system disentangles the mixture of sound inputs into discrete sources that cohere across time. The length of time required for this to occur is termed the "buildup" period. In the current study, we used the buildup period as an index of how quickly sounds are segregated into constituent parts. Specifically, we tested the hypothesis that st...
Experiments suggest that biodiversity enhances the ability of ecosystems to maintain multiple functions, such as carbon storage, productivity, and the buildup of nutrient pools (multifunctionality). However, the relationship between biodiversity and multifunctionality has never been assessed globally in natural ecosystems. We report here on a global empirical study relating plant species richne...
Mass energy absorption coefficients and effective atomic numbers for photon energy absorption, ZPEAeff have been calculated in the energy range from 1 keV to 20 MeV for human tissues, Adipose Tissue, Blood Whole, Bone Cortical, Brain Grey/White Matter, Breast Tissue, Eye Lens, Lung Tissue, Muscle Skeletal, Ovary, Testis, Soft Tissue. Mass energy absorption coefficients and effective atomic numb...
−− Reducing the use of fresh water can lead to energy savings when this is properly planned and executed. Chemical process simulation has proven to be an effective tool for performing a global analysis of water systems to identify routes for maximizing the process efficiency concerning to water recovery. System closure has been introduces in pulp mills resulting in simultaneous buildup of nonpr...
The increasing radiation applications in our daily life makes it essential to protect ourselves from the harms of by using alternative, cheap and natural materials. present study aimed analyze shielding abilities green red clayey soils Oltu/Erzurum Turkey, reinforced with waste tires marble dust. For purpose investigate features samples, attenuation parameters were determined EpiXS software, wh...
The production of thermal lesions in the ocular fundus depends, among other factors, upon the spectral quality of the light incident on the cornea, and the energy-density gradient in the fundus. The latter depends, in turn, upon the concentration of pigment within the granules and the space distribution of the granules within a given stratum or layer. The distribution of pigmented granules vari...
چکیده نمایشگاه های جهانی یا اکسپو عنوانی ست که از سال 1851 میلادی در لندن توسط همسر ملکه انگلستان شکل گرفت ، هدف اولیه این نمایشگاه ها نمایش دستاورد های صنعتی بود، اما در طول 165 سال که این نمایشگاه های برگزار گردیدند ، رویکرد آنها تغییر کرده است . در هر دوره به یک شعار که در واقع دغدغه اصلی جهان، در آن زمان بوده است ، پاسخ داده شده و راه حل کشور های مختلف در مورد آن موضوع به نمایش گذارده شد...
An in vivo dosimetry system that uses p-type semiconductor diodes with buildup caps was characterized for clinical use on accelerators ranging in energy from 4 to 18 MV. The dose per pulse dependence was investigated. This was done by altering the source-surface distance, field size, and wedge for photons. The off-axis correction and effect of changing repetition rate were also investigated. A ...
