This work investigates the effect of different conditions of PFO thermal cracking from two PFO samples on liquid, solid and gas product yield and asphaltene removal efficiency in a new designed experimental setup. No need to use a catalyst, simple operating system and experiment conditions, the ability to use water as a cheap carrier gas and high asphaltene extraction efficiency without the use...

Objective(s): Iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. Molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. However, to date there is no reliable information on the application of the markers in the Iranian pop...

Background & Aims of the Study: Since beta-thalassemia is the most commonly inherited disease in Iran, its preventive and controlling programs are considered vitally important in the healthcare system. This study was conducted to investigate the incidence rate and epidemiology of major beta-thalassemia (MBT) over the last twenty years in Kerman, Iran. Materials and Methods: This cross-secti...

We studied the durations and average speeds of videopulses transmitted through chiral sculptured thin films using a finite–difference algorithm. The chiral STF was either linear or possessed an intensity–dependent permittivity. Videopulse durations tended to decrease with increasing carrier wavelength and to increase, for given carrier wavelength and polarization state, when the chiral STF was ...

Cyclo(L-Lac-L-Val-D-Pro-D-Val)3 (PV-Lac) a structural analogue of the ion-carrier valinomycin, increases the cation permeability of lipid bilayer membranes by forming a 1:1 ion-carrier complex. The selectively sequence for PV-Lac is identical to that of valinomycin; i.e., Rb+ greater than K+ greater than Cs+ greater than or equal to NH+4 greater than Na+ greater than Li+. The steady-state zero-...

Lung cancer (LC) and chronic obstructive pulmonary lung diseases (COPDs; including emphysema and chronic bronchitis) share a common etiology. Despite the known associations of alpha1-antitrypsin deficiency (alpha1AD) with COPD and COPD with LC, few studies examined the association of alpha1AD alleles and LC. We hypothesize that heterozygous individuals who carry a deficient allele of the alpha1...

The implications of a carrier model of ion and substrate cotransport are worked out. Each carrier is assumed to have one ion and one substrate binding site. The model includes features that have not been included in previously published models. These features are the effect of the membrane potential and of the assumption that all carrier forms, with or without bound substrate and with or withou...

According to the demand of advance communication field there should be high data rate in addition to both power efficiency and lower bit error rate. This demand of high data rate can be fulfilled by the single carrier modulation with compromising the trade off between the power efficiency and bit error rate. Again in the presence of frequency selective fading environment, it is very difficult t...

background: salmonella enterica serovar typhi (s. typhi) the cause of the acute febrile disease typhoid fever is the major public health problem in developing countries. asymptomatic carriers are the main sources of typhoid. the aim of this study was to investigate methods for isolation and identification of s. typhi in asymptomatic carriers. materials and methods: two hundred stool samples wer...
