OBJECTIVES Evidence for an association between duration of untreated illness (DUI) with clinical and functional outcome or brain volume (change) in schizophrenia patients is inconclusive. We aimed to investigate the relationship between DUI, outcome and brain volume at illness onset or brain volume change during the first five years of the illness in first-episode patients. METHODS Magnetic r...

BACKGROUND AND PURPOSE Feasibility of brain atrophy measurement in patients with MS in clinical routine, without prior standardization of the MRI protocol, is unknown. Our aim was to investigate the feasibility of brain atrophy measurement in patients with MS in clinical routine. MATERIALS AND METHODS Multiple Sclerosis and Clinical Outcome and MR Imaging in the United States (MS-MRIUS) is a ...

In 1968, Matyas and Radhakrishna introduced the concept of state surface, demonstrating that unsaturated soil volume change is dependent on two independent stress variables, net total suction. For decades basic theory soils has been known, a holistic view elastoplastic response soils, based modified surface approach (MSSA), makes it clear method accounting for roles suction required to quantify...

Researches using existing statistics and data collected from the area of study help officials at decision-making, to improve the region's problems, like the problem of the high rate of accidents in the region, despite the low volume of daily service. The uses of roundabouts in many parts of the world have many advantages over intersections, amongst them are increased safety and capacity and red...

in this paper, the temperature distribution around a moving heat source had been investigated including the phase change and non phase change . in non-phase change state, the governing equation was converted to finite difference equation by finite volume method and the equation was solved by alternating direction implicit method. this method was unconditionally stable . in phase change state, t...

The transient grating (TG) method, which is one of the photothermal techniques, can enable sensitive detection thermal energy with high temporal resolution based on changes in refractive index a material. In addition to energy, TG method also detect any that affect index, such as partial molar volume and absorption spectrum far from probe wavelength. this Perspective, recent studies chemical re...

Gas holdup and bubble size are important parameters for simulation and designing in bubble column reactors. Because based on these parameters, the available gas-liquid interfacial area is defined for mass transfer. In this paper, the results of applying magnetic fields on the velocity field and volume fraction of gas holdup are reported. Hydrodynamics of the bubble column in the reactors is inv...
