BACKGROUND AND PURPOSE During the review of MR studies of multiple patients with polymicrogyria (PMG), it was noted that the patterns of cortical abnormality differed significantly among affected patients. In particular, the cortex appeared very thin in some patients, but was thick in others. The purpose of the present study was to attempt to clarify the cause of the different imaging appearanc...

Myocardial ischemia is characterized by a decrease in phosphocreatine (PCr) and Mg(2+)-ATP contents as well as an accumulation of myosin ATPase reaction products (inorganic phosphate [P(i)], protons, and Mg(2+)-ADP). The possibility that these metabolites play a role in rigor tension development was checked in rat ventricular Triton X-100-skinned fibers. Rigor tension was induced by stepwise de...

This study proposed a cost effective method of wind energy conversion system (WECS) incorporating permanent magnet generator (PMG) and single stage power converter. Axial flux PMG can generate rated voltage and frequency even at a lower speed and hence more suitable for direct drive WECS. To get desired voltage and frequency in continuously varying wind conditions, a new type of WECS with singl...

This paper presents a comprehensive conversion loss analysis of the Power Conditioning System (PCS) for a grid connected Permanent Magnet Generator (PMG) and a Wound Rotor Induction Generator (WRIG) based small wind turbine system. The main focus of the loss analysis is the conduction and switching losses in the semiconductor devices and PCS. The analysis reveals that the WRIG based system with...

The values of these thermodynamic quantities are presented by means of contour diagrams for the range pH 4 to 10 and pMg 1 to 7. These diagrams make the general features of the pH and pMg dependences readily discernible and summarize the results of some 2500 calculations per diagram. There are significant changes in the heat evolved by these reactions over this range of the independent variable...

This paper presents Maximum Power Point Control for variable speed wind turbine driven permanentmagnet generator. The wind turbine generator is operated such that the rotor speed varies according to wind speed to adjust the duty cycle of power converter and maximizes Wind Energy Conversion System (WECS) efficiency. The maximum power point for each speed value is traced using Maximum Power Point...

Agenesis of the corpus callosum (ACC), cerebellar hypoplasia (CBLH), and polymicrogyria (PMG) are severe congenital brain malformations with largely undiscovered causes. We conducted a large-scale chromosomal copy number variation (CNV) discovery effort in 255 ACC, 220 CBLH, and 147 PMG patients, and 2,349 controls. Compared to controls, significantly more ACC, but unexpectedly not CBLH or PMG ...

A path-method is used as a mechanism in object-oriented databases (OODBs) to retrieve or to update information relevant to one class that is not stored with that class but with some other class. A path-method is a method which traverses from one class through a chain of connections between classes and accesses information at another class. However, it is a di cult task for a casual user or even...

The observed equilibrium constant for the hydrolysis of ATP to ADP and inorganic phosphate has been calculated as a function of pH and pMg ( -log (Mg2f)) at ZS”, along with the numbers of moles of H+ and Mg2+ produced per mole of ATP hydrolyzed. This equilibrium constant has also been calculated as a function of pMg and pCa (-log (Ca”+)) at a constant pH of 7.4, along with the numbers of moles ...

The potential biological activity of binary mixtures of some new organophosphorous compounds, aminoalkane- and aminofluorenephosphonates, with (N-phosphonomethyl)-glycine (glyphosate, PMG) was studied. The inhibition of growth of wheat (Triticum aestivum) induced by individual compounds and their equimolar mixtures with PMG was a measure of that activity. The experiments were expected to show i...
