Changes in apparent pH occurring during fast freezing of aqueous buffer solutions and cooling to -196 degrees C were studied by various semiquantitative methods, including simple visual measurements of colour changes with pH indicators, as well as measurements of pH-dependent changes in the e.p.r. (electron paramagnetic resonance) spectra of solutions of three different metalloenzymes. It is co...

The aim of this paper is to create a task-based model for L2 learners to reach native-like pronunciation using technology. The model is based on three major principles. Firstly, language-learning system is that it need to give learners an opportunity to make sense for themselves. Secondly, Build up the modified 3Ms (Meaning Making Mechanisms), (Lian, A.P. 2000) which is operating in the heads o...

Physical inactivity is a determinant of clinical disorders and psychological problems in patients with chronic kidney disease patients. In two satellite clinics, a program of physical activity (PA) was offered to 86 patients undergoing hemodialysis. Of those, 49 patients entered the PA program spontaneously and 37 remained inactive. After six months, a satisfaction self-reported questionnaire a...

We report the discovery with the 100 m Green Bank Telescope of 65 ms radio pulsations from the X-ray pulsar J0205+6449 at the center of supernova remnant 3C58, making this possibly the youngest radio pulsar known. From our observations at frequencies of 820 and 1375 MHz, the free electron column density to PSR J0205+6449 is found to be 140.7± 0.3 cm−3 pc. The barycentric pulsar period P and Ṗ d...

This study demonstrates that a combination of bulk NMR and magnetic resonance imaging measurements of the T(2)-values of water protons can be used to determine the heat-induced changes in the structure and moisture content of fresh chicken meat which had been cooked in a convection oven at 200°C for a range of times. The gravimetric moisture content was also determined for both the raw and cook...

Companies today have several major issues while managing information. Many subsidiaries and departments have developed their own Data Management which has led to a multitude of Operational Databases and sometimes a multitude of Data Marts, policies and processes. Thus, these systems lack sustainability because they are not dynamic and not self-organizing, and so they do not adapt to the continu...

Conventional x-ray computed tomography (CT) scanners are limited in their scanning speed by the mechanical constraints of their rotating gantries, and as such do not provide the necessary temporal resolution for imaging of fast-moving dynamic processes, such as moving fluid flows. The Real Time Tomography (RTT) system is a family of fast cone beam CT scanners which instead use multiple fixed di...

Direct electrical stimulation of functional cortical areas is a standard procedure in epilepsy and glioma surgery. Many previous studies support that stimulation of the motor cortex with short-train pulses is a less epileptogenic alternative to the 50-60Hz 'Penfield' technique. However, whether the short-train stimulation is useful also in mapping of speech areas is unclear. In this case report...

We present five recycled pulsars discovered during a 21-cm survey of approximately 4,150 deg between 15 and 30 from the galactic plane using the Parkes radio telescope. One new pulsar, PSR J1528−3146, has a 61ms spin period and a massive white dwarf companion. Like many recycled pulsars with heavy companions, the orbital eccentricity is relatively high (∼0.0002), consistent with evolutionary mo...

Abstract Background The diagnosis of atrial infarction is often masked by the frequent association with ventricular infarction. For this reason, electrophysiological and structural consequences selective ischemia are poorly understood. Purpose objective study was to analyze alterations in ECG, local electrograms, multifrequential myocardial impedance a new experimental model acute chronic Metho...
