OBJECTIVE Prone positioning, iterative reconstruction (IR-OSEM) and electrocardiography (ECG) gating have been demonstrated to improve the specificity of myocardial perfusion SPECT (MPS) in the diagnosis of coronary artery disease. METHODS The gated supine and prone MPS images of 45 patients were reconstructed with both IR-OSEM [supine (SIR) and prone (PIR)] FBPs [supine (SFBP), prone (PFBP)]...

The Great East Japan Earthquake of 2011 had profound impacts in various ways because it was a complex disaster. In addition to the earthquake itself, tsunami and nuclear accident were even more severe for human lives, health, economy, environment. Researchers around world responded study topics spanned from natural sciences social sciences. this study, we analyzed over 20,000 academic records c...

Aiming at nonlinear flow in fractured porous media, based on the finite volume method, discrete equations of Darcy and Forchheimer fracture were derived, a solution method for coupling is proposed. The by proposed single intersecting verified against Frih’s solution. Based this behavior rock deep-buried tunnels under high water heads was discussed. results show that hydraulic gradient surroundi...

Transport risk analyses based on the RADTRAN code have been met with continual demands for increased spatial resolution of variations in population densities and other parameters employed in the calculation of risk estimates for transport of radioactive material (RAM). With the advent of geographic information systems (GISs) large quantities of data required to describe transport routes, which ...

Ensuring safety on roadways and controlling conflicting merging streams of traffic at signalized intersections has become a major concern for transportation engineers road users globally locally. Many factors contribute to accident occurrence segments with driver behavior being the contributor.  Other include those related vehicle road. The primary aim this study is understand impact diffe...

Although genotyping-by-sequencing (GBS) enables the efficient and low-cost generation of large numbers of markers, the utility of resultant genotypes are limited, because they are enormously error-prone and contain high proportions of missing data. In this study, we generated single nucleotide polymorphism (SNP) markers for 109 recombinant inbred lines of melon (Cucumis melo L.) using the GBS a...

Background & Aims of the Study: Accidents in water networks can lead to increase the uncounted water, costs of repair, maintenance, restoration and enter water contaminants to water network. The aim of this study is to survey the accidents of Qom rural water network and choose the right approaches to reduce the number of accidents. Materials & Methods:  In this cross...

Road accidents have a definite impact in terms of lives, welfare and traffic congestion, especially with increase in mobility and number of overall vehicles. Prevention policies can greatly benefit from data analysis of positions and accident characteristics. This work presents a practical integration of open source software for the implementation of an instrument to insert, store, automaticall...

RATIONALE The inflammatory processes that initiate and propagate atherosclerosis remain poorly understood, largely because defining the intravascular behavior of immune cells has been technically challenging. Respiratory and pulsatile movements have hampered in vivo visualization of leukocyte accumulation in athero-prone arteries at resolutions achieved in other tissues. OBJECTIVE To establis...
