Functional connectivity between two voxels or regions of voxels can be measured by the correlation between voxel measurements from either PET CBF or BOLD fMRI images in 3D. We propose to look at the entire 6D matrix of correlations between all voxels and search for 6D local maxima. The main result is a new theoretical formula based on random field theory for the p-value of these local maxima, w...

–Phosphorus is one of the most vital macronutrients required for the growth and development of plants. A large number of microorganisms present in the rhizosphere are known to solubilize and make available the insoluble phosphorus in the available form to the plants. A total of fifty phosphate solublizing bacterial colonies were isolated on the Pikovskaya’s (PKV) agar medium, containing insolub...

Steam explosion at 180, 190 and 200°C for 15min was applied to sugarcane straw in an industrial sugar/ethanol reactor (2.5m(3)). The pretreated straw was delignificated by sodium hydroxide and hydrolyzed with cellulases, or submitted directly to enzymatic hydrolysis after the pretreatment. The pretreatments led to remarkable hemicellulose solubilization, with the maximum (92.7%) for pretreatmen...

The bio-solubilization of Jordan phosphorite by the phosphate-solubilizing fungus Aspergillus niger has been investigated. The effect of the phosphate concentration in the liquid medium, the duration of biodecomposition, titratable acidity and the effect of preliminary mechanical activation on the process of dissolution have been studied. The investigations indicate that almost complete extract...

The objective of the present study was to compare the ability of experimental and commercial xylanases to degrade, in vitro, the arabinoxylan (AX) fraction in digesta from 28-d-old piglets fed a wheat (Triticum aestivum)-based diet (49% wheat). Pigs were euthanized at 1, 2, 3, or 4 h after feeding; stomach and ileum contents were isolated and frozen and later used for the in vitro studies. Xyla...

This article introduces a new tri-parameter law of corresponding states from the known regularities, namely the LIR and Zeno line for dense fluids (when Tz=Tc). Two of these parameters are the Zeno line parameters and the third parameter (the fluid parameter), has been obtained from the LIR, this parameter is solely dependent upon the fluid characteristics. The third parameter ca...

Sera from 20 patients with suspected or known coronary artery disease were measured for thyroxine (T4), tri-iodothyronine (T3), tri-iodothyronine uptake ratio (T3UR), thyroid stimulating hormone (TSH), and reverse tri-iodothyronine (rT3), before and after maximal or near-maximal exercise. On the average the patients achieved 92% (rang 68-108) of the predicted maximum heart rate. There were no s...

The advantages of triple-site ventricular pacing (Tri-V) compared to conventional biventricular site pacing (Bi-V) have been reported. We sought to identify the predictors of acute hemodynamic Tri-V responders. Acute hemodynamic studies were performed in 32 patients with advanced heart failure during Tri-V implantation. After the right ventricular (RV) and left ventricular (LV) leads were impla...

Abstract Many agricultural researches have been performed to improve soil productivity. Nitrogen (N) and Phosphorus (P) are essential elements which are utilized by the plants in large amounts. Phosphorus can be provided by applying chemical fertilizers. Microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this proces...
