This paper discusses different important gas permeation models such as “Maxwell”, “Bruggeman”, “Lewis-Neilson”, and “Pal” models to predict “Mixed Matrix Membranes” (MMMs) performance. The main parameter considered and discussed is the permeability of Hydrogen on Carbon Nanotubes (CNTs)-MMM. For evaluation of the theoretical models, experimental data of permeability for H2 were compa...
This article reports on a meta-evaluation, focused on utilization, in a state in southern Brazil. This was a single case study with primary data collection using semi-structured interviews with health department administrators and staff. Content analysis used categories defined in the evaluation matrix: political and organizational context and implementation of evaluation. The political and org...
to test the reasonability of applying journal-specific indicators with the purpose of evaluating individual researchers, the present study attempted to examine the structural similarities between journal-evaluation indicators (i.e. jif, snip and sjr) and author-evaluation ones (i.e. publication counts, citation per paper, and h and g indices) through factor analysis. the iranian papers having p...
Abstract Under the assumption of a low intensity flow incoming requests and high speed their service, M|M|1 system utilization factor model is considered. It estimated for small part observation time. Approximate relations are obtained factor. Its simple probabilistic in form mixture proposed. A comparison with results simulation carried out.
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...
In the present study, potential of finite element based molecular structural mechanics (MSM) for evaluating stress concentration factor of single-layered graphene sheets (SLGSs) with elliptical vacancies is successfully addressed. The MSM approach mimics the interatomic forces of the nanostructure by defining an equivalent frame structure containing beam elements. To obtain the mechanical and c...
Background: Congenital factor XIII (FXIII) deficiency is one of the rarest bleeding disorders with a prevalence of one per 2 million in the general population. The disorder is accompanied by a high rate of life-threatening bleeding. Due to normal results of routine coagulation tests, diagnosis of the disorder is challenging, but molecular methods can be used for precise diagnosis. Direct mutati...
Comparison between the results from the design procedure based upon the value of D2L (volume of iron) and IEC standard used by manufacturers indicates that the basic design equation of electrical machines must be modified by a proper modification factor. This modification factor is evaluated for single- and three-phase induction motors and its variation with motor rating and poles number is obt...
OBJECTIVE Three psychosocial characteristics associated with cardiovascular disease (CVD)-depression, hostility, and social support-tend to correlate with one another. However, the causes of each characteristic and why they tend to co-occur are not completely understood. Therefore, the current study used a twin design to examine the relative contributions of genetic and environmental influences...
