BACKGROUND Widespread cortical atrophy in Amyotrophic Lateral Sclerosis (ALS) has been described in neuropathological studies. The presence of cortical atrophy in conventional and scientific neuroimaging has been a matter of debate. In studies using computertomography, positron emission tomography, proton magnetic resonance spectroscopy and conventional T2-weighted and proton-weighted images, r...

Hippocampal structural and functional integrity impacts on multiple remote areas of the brain, and this connectivity is central to multiple cognitive functions in healthy and disease. We studied associations of hippocampal metabolic markers N-acetyl aspartate (NAA) and glutamate (Glu and Glx; assessed with 1H magnetic resonance spectroscopy) and brain grey matter (studied with voxel-based morph...

the present study was carried out in 2011 to measure concentration of heavy metals chromium and tin in liver and muscle tissue of liza aurata (golden grey mullet) in estuaries of the rivers babolroud, tajan and gorganroud. accordingly, after sampling the target are asandisolating muscle (18samples) and liver (18samples) tissues, they were digested and analyzed using graphite furnace atomic abso...

Abstract The problem of the reliability ammunition storage environment is a hot topic in field modern military research, and key to find out main factors that affect sensitive components. Grey relational entropy analysis method can order influencing factors, but it can’t judge influence size correlation. Pearson analyze linear correlation better. Therefore, this paper proposes for complex probl...

Traditional rural residential construction has the problems of high energy consumption and severe pollution. In general, with sustainable development in the construction industry, rural residential construction should be aimed towards low energy consumption and low carbon emissions. To help achieve this objective, in this paper, we evaluated four different possible building structures using AHP...

The recognition of wood species is needed is many areas like construction industry, furniture manufacturing, etc.,. The wood is traditionally classified by human experts. But human identification of wood type is not accurate and the manual identification is a time consuming process. So in this study, an intelligent recognition for identification of wood species was developed. This study uses im...
