The presence on the Virgo cluster outskirts of spiral galaxies with gas deficiencies as strong as those of the inner galaxies stripped by the intracluster medium has led us to explore the possibility that some of these peripheral objects are not newcomers. A dynamical model for the collapse and rebound of spherical shells under the point mass and radial flow approximations has been developed to...

BACKGROUND During the last three decades, ethics committees have been formed with a growing trend. These committees have a satisfactory and effective impact on the pattern of patient care and its performance. The medical ethics committee is considered one of the most active committees in hospitals, having the aim of providing necessary approaches for the optimal use of the findings in empirical...

About half of the baryons in the local Universe are thought to reside in the so-called warm-hot intergalactic medium (WHIM) at temperatures of 0.1-10 million K. Thermal soft excess emission in the spectrum of some cluster outskirts that contains OVII and/or OVIII emission lines is regarded as evidence of the WHIM, although the origin of the lines is controversial due to strong Galactic and sola...

Mashhad Plain affects by a series of active faults in the northern margin of the Binalud and the southern margin of the Kopet-Dagh mountain ranges. The activity of these faults forms the morphology of the stepped bedrock of the Plain. In addition, the faults’ activities in the Quaternary period are the main effective parameters in thickness and texture of aquifer deposits in Mashhad Plain. In t...

Is translational research enhanced by the proximity of research institutes to hospitals? For scientists at the UK's National Institute of Medical Research, which is facing relocation from London's outskirts to its center, the question is no longer academic.

With the increasing demand for energy globally and need to reduce fossil fuels, paying attention renewable clean sources is necessary. Solar systems are viable among heat electricity generation. In this study, an Off-grid solar system was investigated by considering effect of climate conditions environmental factors such as dust on performance PV panels. Performance efficiency using PVsyst soft...

Depressor septi nasi is an important muscle in the nose and upper lip dynamics.1-4 Hypertrophy of this muscle leads to a deformity during smiling presented by depression of nasal tip, shortening of upper lip, and a horizontal crease in upper lip.4 Rhino-gingivolabial syndrome was defined as depression of nasal tip, shortening of upper lip, and gingival show. This syndrome was attributed to the ...

Free living amoebae (FLA) are frequently distributed in environment, such as air, water, dust and soil (1). Some strains of Acanthamoeba spp. are non-pathogen, while others are pathogenic in immunocompromised patients or even healthy persons (2-4). Acanthamoeba encephalitis is rare and less likely to be diagnosed with successful medical intervention. These amebas can carry and transmit importan...

Milk fever and subclinical hypocalcemia are the most important macro-mineral metabolic disorders that affect transition dairy cows. Many studies have shown that cows with subclinical hypocalcemia are also prone to many diseases and disorders. The drain of Calcium (Ca) during early lactation represents a significant increase in Ca demand over that for late fetal growth and physiological maintena...
