1. introduction as the pressure of porous water increases in sand soils and saturated loose layers during an earthquake, the soil tendency to reduce its own volume leads to a decrease in the soil’s multifaceted tension. this way, the shear strength of the soil strongly decreases and comes close to zero. this phenomenon is called liquefaction. soil liquefaction is the cause of much destruction o...
Expertise with print is likely to optimize visual processes for recognizing characters of a familiar writing system. While brain activations have been identified for words and letter strings compared to other stimuli, relatively little work has focused on the neural basis of single letter perception. English readers and Chinese-English bilinguals participated in an ERP study and performed a 1-b...
Carrier dynamics in graphene films on CaF2 have been measured in the mid infrared region by femtosecond pump-probe spectroscopy. The relaxation kinetics shows two decay times. The fast time component is ~0.2 ps, which is attributed to the mixture of initial few ultrafast intraband and interband decay channels. The slow component is ~1.5 ps, which is primarily assigned to optical phonon-acoustic...
This study investigated the effects of dating and school environment on implicit and explicit math attitudes among adolescent girls who applied to the Young Women’s Leadership Charter School (YWLCS), which emphasizes math and science competence. Ninety-three female adolescents, (66 YWLCS and 27 control participants), completed two web-based study sessions. The first session was available beginn...
In academic and organizational domains, performance measures are often used to assess achievement or aptitude. When certain groups of people systematically underperform on such measures, a common interpretation is that the groups differ in inherent ability. However, social psychological research over the past 15 years has documented a phenomenon called stereotype threat whereby subtle situation...
The COVID-19 pandemic has placed enormous strain on countries around the world, exposing long-standing gaps in public health and exacerbating chronic inequities. Although research analyses have attempted to draw important lessons how strengthen preparedness response, few examined effect that fragmented governance for had effectively mitigating crisis. By assessing ability of systems manage from...
Rock typing is an essential part of building geological model for an asset. Millions of dollars are invested in logs, core measurements, SCAL studies and geological interpretation that result in definition of different rock types. In most caes rock types that are identified in a reservoir do not have crisp boundaries and display overlapping characteristics. During the upscaling process, multipl...
چکیده زمینه و هدف: ناباروری یکی از مشکلات عمده سلامت تولیدمثلی است که 15-10% زوجین را گرفتار می کند. براساس گزارش سازمان بهداشت جهانی 80-50 میلیون زوج نابارور در سراسر جهان وجود دارد. فعالیت فیزیکی یکی از فاکتورهای سبک زندگی است که می تواند تأثیرات مثبت یا منفی بر سیستم تولیدمثلی داشته باشد. برهمین اساس این پژوهش با هدف توصیف و مقایسه وضعیت فعالیت فیزیکی زوجین بارور و نابارور شهر کرمانشاه در سا...
