the paper presents the results of an investigation on the acoustic performance of vertical profile parallel barriers with quadratic residue diffuser tops and faces. a 2d boundary element method (bem) was used to predict the barrier insertion loss. the results of rigid and with absorptive coverage were also calculated for comparisons. using qrd on the top surface and faces of all vertical profil...

October 11, 2016 People face a multitude of barriers when attempting to transition to the community from correctional or forensic institutions, including symptom management, substance abuse, and weak social ties. However, labeling and stigma processes has not been conceptualized as a barrier to successful transition in and of itself. A systematic review was conducted to collect and synthesize t...

We studied detour responses of two species of poeciliid fish (Gambusia hoolbroki and Girardinus falcatus) faced with a vertical-bar barrier, through which conspecifics of the same or different sex or a simulated-predator (which induced detour behaviour for predator-inspection responses) were visible. Both species showed a consistent bias to turn leftward when faced with the predator, and a cons...

Open educational resources (OERs) provide opportunities as enablers of societal development, but they also create new challenges. From the perspective of content providers and educational institutions, particularly, cultural and context-related challenges emerge. Even though barriers regarding large-scale adoption of OERs are widely discussed, empirical evidence for determining challenges in re...

objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...

background: hyperthyroidism as a risk factor for stroke is not conclusive. there are no definite data on the relationship between ischemic cerebrovascular injury and hyperthyroidism. this study was designed to define whether the outcomes of post-ischemic stroke injury are influenced by chronic hyperthyroidism. methods: two groups of hyperthyroid (ht) and control euthyroid rats of equal numbers ...

background: lifestyle-modification programs including physical activity are essential for both treatment and prevention of type 2 diabetes mellitus ( t2dm ). however, factors associated with physical activity among patients are poorly understood. this study applied social-cognitive theory (sct) for predicting determinants of physical activity among women with t2dm in iran, 2013. methods: in thi...

Introduction: A neurodevelopmental disorder, autism typically identified with three primary behavioral consequences, such as social impairment, communication problems and limited or stereotypical behavior. Because of its co-morbidity and lack of therapeutic options, autism is a global economic burden. A short chain of fatty acid, propionic acid formed biologically by gut microbiome. Propionic a...

Understanding the dynamics of reciprocation is of great interest in sociology and computational social science. The recent growth of Massively Multi-player Online Games (MMOGs) has provided unprecedented access to large-scale data which enables us to study such complex human behavior in a more systematic manner. In this paper, we consider three different networks in the EverQuest2 game: chat, t...

An exploratory study was conducted to answer the following questions: What are older adults' perceptions of social media? What educational strategies can facilitate their learning of social media? A thematic map was developed to illustrate changing perceptions from the initial unanimous, strong negative to the more positive but cautious and to the eventual willingness to actually contribute con...
