BACKGROUND Heat waves are extreme weather events that have been associated with adverse health outcomes. However, there is limited knowledge of heat waves' impact on population morbidity, such as emergency department (ED) visits. OBJECTIVES We investigated associations between heat waves and ED visits for 17 outcomes in Atlanta over a 20-year period, 1993-2012. METHODS Associations were est...
Background and Aim: Considering the great advances and extensive use of cell phones and its effects on the human communications and interactions, investigation of potential negative effects of cell phones on the users' health is necessary. The aim of this study was to determine the effect of the distance between cell phones and brain tissue on the temperature of the central and gray matters of ...
A12-lead ECG was obtained from a 72-year-old man with a core body temperature of 85°F (Figure 1). The ECG shows severe sinus bradycardia with prolonged PR, prolonged QRS complex, prolonged QT interval, and an extra deflection at the end of the QRS complex (Osborn waves) (arrows). A second 12-lead ECG obtained 24 hours later, after the patient had been rewarmed to 98°F, was normal (Figure 2). Hy...
Using the quantum hydrodynamic (QHD) model for quantum plasma at finite temperature the modulational instability of electron plasma waves is investigated by deriving a nonlinear Schrodinger equation. It was found that the electron degeneracy parameter significantly affects the linear and nonlinear properties of electron plasma waves in quantum plasma. Keywords—Amplitude Modulation, Electron Pla...
Heat waves are among natural hazards with the most severe consequences for human society, including pronounced mortality impacts in mid-latitudes. Recent studies have hypothesized that the enhanced persistence of atmospheric circulation may affect surface climatic extremes, mainly the frequency and severity of heat waves. In this paper we examine relationships between the persistence of the Hes...
Underwater Acoustic Tomography (AT) system transmits acoustic waves into the water. The AT systems continuously measure the physical characteristics of the flow in rivers, seas and the oceans. The AT systems are synchronized via a GPS clock connectied to the satellites. Hence, the systems transmit the acoustic waves at the same time. The systems record the arrival time of acoustic waves. After ...
introduction: human eye is a sensitive part of human body with no direct protection and due to its lack of protection against the external heat waves, studying the temperature distribution of heat waves on the human eye is of utmost importance. various lasers are widely used in medical applications such as eye surgeries. the most significant issue in the eye surgeries with laser is estimation o...
Plasmas with high ion-temperature of several keV and strong temperature anisotropy of more than 10 have been produced by using ion-cyclotron range of frequency (ICRF) heating in the GAMMA 10 tandem mirror. In such high performance plasmas with strong anisotropy, high-frequency fluctuations, so-called Alfvén-Ion-Cyclotron (AIC) waves, are spontaneously excited. The AIC waves have several discret...
