Introduction Positive airway pressure (PAP) is the standard treatment for patients with moderate-to-severe obstructive sleep apnea (OSA); a sleep-related breathing disorder (SRBD) characterized by episodic complete or partial upper airway occlusion during sleep.1 Over the past years, the relationship between SRBD and cardiac arrhythmias have been thoroughly investigated.2-7 Previous studies have shown that obstructive sleep apnea syndrome (OSAS) predisposes to clinically significant nocturnal impairment

The classical theory of Raman Effect was developed by G. Placzek in 1934. According to the classical theory of electromagnetic radiation, electric and magnetic fields oscillating at a given frequency are able to give out electromagnetic radiation of the same frequency. Electromagnetic radiation theory can explain light scattering phenomena. When deriving the Raman Effect, it is generally easiest to start with the classical interpretation by considering a simple diatomic molecule as a mass on a

The expansion of Universe The universe is compose of billions of stars, Milky Way, and Galaxies. The study of these three area of the universe has been done by many scientist. However, a person named Edwin Powell Hubble discovered something beyond Milky Way and Galaxies, which is called the Nebulae. According to Hubble, he stated that “Until recently those outer regions in the realm of speculation … they appear as small faint clouds mingled among the stars and many of them have long been known by

“An Occurrence at Owl Creek Bridge” is a cleverly written story by Ambrose Bierce that takes the reader through a psychological journey fabricated by the main character, Farquhar, in his last moments. But throughout the journey, Farquhar and the readers are tricked into believing this fictional dream is really occurring. In the critical articles by Peter Stoicheff, James Powers, and Harriet Kramer Linkin, all three authors point out that Bierce uses the study of the mind and its behavior, or

Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness (EDS) causing uncontrollable and sometimes inappropriate napping. Though the naps are often refreshing their frequent occurrences can severely impair daily social functioning. Apart from EDS the cardinal symptoms are; hypnagogic hallucinations, sleep paralysis, sleep onset rapid eye movement periods (SOREMP) and approximately 50% of all patients also suffer from cataplexy; sudden episodes of emotionally triggered

Location of STATCOM for Power Flow Control Dr..Neelakantappa, Narasapur, Hyderabad.,India Dr.AmjanShaik Narasapur, Hyderabad.,India ABSTRACT: Power flow control in a long transmission line plays a vital role in electrical power system. This paper uses the shunt connected STATCOM for the control of voltage and power flow. The proposed device is used in different locations such as sending end, middle and receiving end of the transmission line. The PWM control is used to generate the firing pulses

related industries experience growth. And the housing market realizes loss when related industries experience loss. Housing is interconnected with many other sectors and industries, so it is not sound to solely blame housing markets for their own oscillations. A major contributor to the Savings-Loans and Foreclosure crisis was unpaid loans (Root). Banks were making loans to prospective and current homeowners without sufficient guarantee of return on investment (ROI). It is this default of loaning on

The “squiggly lines” represent the level of the water’s surface elevation in the reservoir of Lake Mead. The graph calculates when the reservoirs level increases and when there is a drought. The reservoir was formed by the Hoover Dam on the Colorado River in 1937 to provide water supply and began filling. Lake Mead was filled to a higher capacity in 1942 and hit a drastic low during the 1950’s drought. After the drought, it filled up in 1958 and didn’t drop again until 1967 during the filling of

FOURIER SERIES AND ITS SOME APPLICATIONS P. Sathyabama Assistant professor, Department of Mathematics, Bharath collage of science and management, Thanjavur- 5 Abstract The Fourier Series, the founding principle behind the field of Fourier Analysis, is an infinite expansion of a function in terms of sines and cosines.In physics and engineering,expanding functions in terms of sines and cosines is useful because it allows one to more easily manipulate functions.In particular, the fields of electronics

(2) Metaphase II-Anaphase II transition (resumption of the second meiosis) During resumption period of cell cycle, sister chromatids pass anaphase/telophase transition and completed meiosis II by extrusion of the second polar body. After that, chromatin decondensation and the pronuclei formation are occurred. In this stage, the important proteins are involved in resumption of meiosis II composed of G-protein, CaM kinase II, APC/C and separase. Guanine nucleotide-binding regulatory proteins (G-proteins)
