Sepoy, S. S., was admitted to the Indian MilitaryHospital, Alipore, on 19th March, 1932, complaining of severe headache, pain all over the body, and fever which started without shivering. Examination.?A well-nourished man, temperature? 103?F.; pulse?100 per minute, regular, soft, markedly dicrotic; abdomen soft, some tenderness in the right iliac fossa, superficial abdominal reflexes present; l...

Enhanced formation of superoxide radicals has been proposed to play a major role in the development of nitrate tolerance in humans. We tested the effects of vitamin C (Vit-C) supplementation on glyceroltrinitrate (GTN)-induced hemodynamic effects during 3-d nonintermittent transdermal administration of GTN (0.4 mg/h) in nine healthy subjects. Tolerance development was monitored by changes in ar...

ABSTRACT Introduction: The formation and propagation of pulse waves are mainly accomplished by coordinating the heart vascular system. contraction relaxation sources waves. aorta vibrates regularly as contracts. This vibration propagates forward along elastic blood vessel to form a wave. wave contains very rich physiological pathological information about cardiovascular If there is problem with...

a critical protection requirement for grid connected distributed generators (dg) is anti-islanding protection. in this paper, a new islanding detection method for any possible network loading is proposed based on utilizing and combining various system parameter indices. in order to secure the detection of islanding, eight intentional disturbances are imposed to the system under study in which t...

Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...

To the Editor: We have read the recent letter by Hermeling et al. entitled “Potentials and Pitfalls of Local PWV Measurements,”1 discussing the advantages and challenges for local pulse wave velocity (PWV) measurements. The letter was in reference to an article by Vappou et al. regarding pulse wave imaging measurement of arterial stiffness in vivo.2 In the common carotid artery, due to the susc...
