We discuss the nonabelian world-volume action which governs the dynamics of N coincident Dp-branes. In this theory, the branes’ transverse displacements are described by matrix-valued scalar fields, and so this is a natural physical framework for the appearance of noncommutative geometry. One example is the dielectric effect by which Dp-branes may be polarized into a noncommutative geometry by ...

This paper explores the impact of demographic changes on the housing market in the US, 1st by reviewing the facts about the Baby Boom, 2nd by linking age and housing demand using census data for 1970 and 1980, 3rd by computing the effect of demand on price of housing and on the quantity of residential capital, and last by constructing a theoretical model to plot the predictability of the jump i...

Baby boomers will begin entering old age in 2011. They will be the largest and most diverse cohort ever to experience this life-course transition. The sheer number of baby boomers has challenged institutions time after time (Dychtwald, 1990). Despite extensive speculation regarding the political, economic, and social impact that the aging of baby boomers will have on American society, no one ha...

We argue that the giant graviton configurations known from the literature have a complementary, microscopical description in terms of multiple gravitational waves undergoing a dielectric (or magnetic moment) effect. We present a non-Abelian effective action for these gravitational waves with dielectric couplings and show that stable dielectric solutions exist. These solutions agree in the large...

introduction : adverse health effects of exposure to environmental tobacco smoke (ets) among non-smokers have been studied occasionally in developing countries. the aim of this study was to determine the effects of exposure to ets on outcome in pregnancy methods: in this descriptive and analytical study 600 non-smoking women delivering a singleton live baby were studied in delivery room in haja...

In this study, the authors reported a case of woman with severe compulsion who became pregnant during the Repetitive transcranial magnetic stimulation. We carried out Repetitive transcranial magnetic stimulation and behavior therapy simultaneously after repeated medications' refraction. The patient received 20 sessions 1 Hz Repetitive transcranial magnetic stimulation in right dorsolateral pref...

Background: Congenital pouch colon (CPC) is a rare variant of high anorectal malformation. More and more varied associations CPC with other entities are being added to the literature. Case presentation: A 1-day-old male baby presented emergency room marked abdominal distension absent anal opening. On exploration, was found have (Type 2) colonic atresia. This association has not been reported in...

“You look like an angel, talk like an angel, walk like an angel, but you are the devil in disguise.” When Elvis Presley sang those words, he could have been describing my patient, a 4-month-old infant brought in by the Kaiser Permanente advice nurse because of a fever of 100.7. He had no other symptoms and had been breastfeeding well. His 3-year-old sister “had a cold a few days ago and is now ...

Congenital diaphragmatic hernia (CDH) is a rare condition. The reported incidence of intrathoracic renal ectopia due to CDH is also rare. A right-sided thoracic kidney is much less common due to the location of the liver. Isolated intrathoracic kidney is usually asymptomatic and diagnosed incidentally on chest imaging. The authors report on a 21days old female infant with late-presenting right ...
