ABSTRACT Shell galaxies make a class of tidally distorted galaxies, characterized by wide concentric arc(s), extending out to large galactocentric distances with sharp outer edges. Recent observations young massive star clusters in the prominent shell NGC 474 suggest that such systems host extreme conditions formation. In this paper, we present hydrodynamic simulation galaxy merger and its tran...

Microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. In some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. Maintaining higher biosorption capability and understanding t...

background trauma constitutes a major public health problem in our country and contributes significantly to unacceptably high morbidity and mortality. objectives this study aimed to evaluate the epidemiology of trauma in dead patients referred to shahid rajaee trauma hospital, shiraz, iran. patients and methods in a cross-sectional study, all patients with trauma admitted to our center were enr...

This study intends to investigate the realizations and functional patterns of shell nouns in Applied Linguistics research articles.  To this end, fifty research articles in the field of Applied Linguistic were selected from Journal of English for Academic Purposes and journal of English for Specific Purposes published by Elsevier.  The articles were analyzed for the realizatio...

Though the congeners Nutricola (=Transennella) confusa and Nutricola tantilla occupy an important ecological niche on mudflats, there is little published information concerning their population dynamics. We sought to determine what causational factors influence shifts in the relative distributions of these clams. Twelve cores were taken from Westside Park in Bodega Bay Harbor, California, in ar...

This paper proposes an adaptive approximation-based controller for uncertain strict-feedback nonlinear systems with unknown dead-zone nonlinearity. Dead-zone constraint is represented as a combination of a linear system with a disturbance-like term. This work invokes neural networks (NNs) as a linear-in-parameter approximator to model uncertain nonlinear functions that appear in virtual and act...

Introduction: Nanoparticles have several exciting applications in various fields of biomedicine. It has been found that among different classes of nanoparticles core/shell is most promising for field of nano-medical imaging and therapy due to their distinct advantages. The core/shell type nanoparticles can be generally comprising of two nanoparticles one act as a core (inner ma...

in 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for xenia or metaxenia in persian walnut. pistillate flowers of ‘jamal’, ‘chandler’, ‘hartley’ and ‘pedro’ were crossed with the pollen of ‘serr’, ‘z60’ and ‘damavand’. the pistillate flowers on each female parent were covered about one week ...
