Developmental biologist Lucy Shapiro, PhD, told 2015 graduates of the School of Medicine how, as a basic scientist who spent most of her life studying singlecelled bacteria, she stepped out of her laboratory and onto the global stage to try to help the world avert a potential disaster. “About 15 years ago, I sat up and looked around me and found that we were in the midst of a perfect storm,” sa...

design and implement of a strategy to improve employee's attitude, emotions and performance is an important task of managers. because of the lack of enough latitude and diversity in certain jobs, it causes mental fatigue, stress, dissatisfaction, low level of organizational commitment, emotional harms; lose self-confidence and ultimately reduction in job performance. this study is designed to i...

We investigate the relationship between latitude and incidence of melanoma among Whites in different age groups using data from different continents. Relevant data for Whites were obtained for 59 regions around the world. A statistical analysis was carried out using regional dummy variables to eliminate spurious statistical correlation due to clustering. Simple correlation between latitude and ...

Long-period maintenance of software often causes the original program modularization to decay, resulting in a degraded quality software. Placement artifacts, namely code files or classes suboptimal manner among packages is one most common this decaying Software remodularization (remodularization) an old reverse engineering approach that helps alleviating issue by improving modularization. Howev...

MIPAS/ENVISAT data of nighttime NO2 volume mixing ratios (VMR) from 2007 until 2012 between 40 km and 62 km altitude are compared with the geomagnetic Ap index and solar Lyman-α radiation. The local impact of variations in geomagnetic activity and solar radiation on the VMR of NO2 in the lower mesosphere and upper stratosphere in the Northern Hemisphere is investigated by means of superposed ep...

Introduction: As a practical test of the IMPACT program [1] automated method of measuring crater geometry, we have been exploring its use for studying the degradation history of impact craters in the polar regions of Mars. These regions hold important clues to the geologic and climate history of Mars, because this is where most of the volatiles are expected to occur. As an extension of our prev...

considering that the effective yield of a panel is equal to its total number of hours of solar radiation and temperature, only the effects of temperature and solar radiation intensity at the maximum power point (mpp) are investigated in this article. by collecting temperature data, sun's radiation hours from six synoptic meteorological stations in kermanshah province over the course of an ...

A super–rotating atmosphere with equatorial winds of ∼ 35m s is simulated using a simplified Venus General Circulation Model (GCM). The equatorial super-rotation in the model atmosphere is maintained by barotropic instabilities in the the mid–latitude jets which transport angular momentum towards the equator. The mid–latitude jets are maintained by the mean meridional circulation and the moment...
