Gliosarcoma (GSM) is a rare primary malignant brain tumour accounting for less than 0.5% of all intracranial tumours. It has a biphasic histological composition, demonstrating both gliomatous and sarcomatous elements. In clinical practice GSM are generally managed similarly to glioblastoma multiforme (GBM). However, unique features including its clinical propensity for extra-cranial metastasis,...

The levels of maximum power density of GSM signals in the cities of Lagos, Ibadan and Abuja were studied. Measurements were made with a calibrated hand held spectrum analyzer 200m away from 271 base stations, at 1.2m to the ground level. The maximum GSM 900 signal power density was 139.63μW/m in Lagos, 162.49μW/m in Ibadan and 5411.26μW/m in Abuja. Also, the maximum GSM 1800 signal power densit...

In this paper, we give a review of the tensor method for treating the propagation of scalar and electromagnetic Gaussian Schell-model (GSM) beams. Partially coherent complex curvature tensor is introduced to describe a scalar astigmatic partially coherent GSM beam with twisted phase (i.e., twisted anisotropic GSM beam). A tensor ABCD law for treating the propagation of scalar twisted anisotropi...

BACKGROUND Vulnerability of the carotid plaque might be useful as a predictor for ischemic stroke risk. The gray-scale median (GSM) of the carotid plaque at B-mode imaging has been described as an objective tool to quantify vulnerability. However, its use is disputed in the published literature. This study sought to validate the GSM as a predictor for carotid plaque vulnerability. METHODS We ...

Introduction: Over the last decade, exposure to electromagnetic waves due to base station antennas has increased. This study was planned to evaluate the effects of different electrical field strengths with 950 MHz waves of the GSM mobile phone system on the excitatory postsynaptic potentiation (EPSP) slope of the dentate gyrus long-term potentiation (LTP). Material and Methods: Twenty four naiv...

-Industrial wireless communication opens up many new possibilities for highly flexible and efficient solutions. In this paper use of GSM network is for energy metering system incorporating the widely used GSM network. In many countries GSM network is popular because of its vast coverage area & cost effectiveness. Using GSM as the medium for metering system provides a cheap, wireless, seamlessly...
