Hot and cold water, in comparison to room temperature water, ingested by normal young men, profoundly alters esophageal motor function. Cold water slows or abolishes esophageal peristalsis, prolongs the contraction wave in the distal esophagus, produces a delayed but prolonged relaxation of the lower esophageal sphincter, and regularly causes a lower esophageal sphincteric contraction of increa...

A total of 123 water samples were examined in parallel by culture and semi-nested PCR for the presence of Legionella. They comprised: 35 samples of hot water distributed by the urban municipal water supply system (MWSS) taken in institutions, 45 samples of hot water distributed by urban MWSS taken in dwellings, 27 samples of cold water distributed by rural MWSS taken in dwellings, and 16 sample...

Though one dimensional self-gravitating N -body systems have been studied for three decade, the nature of relaxation was still unclear. There were inconsistent results about relaxation time; some initial state relaxed in the time scale T N tc, but another state did not relax even after T N 2 tc, where tc is the crossing time. The water-bag distribution was believed not to relax after T N tc. In...

Birth traits of 68 Angus and 49 Charolais x Angus calves sired by four Angus and seven Charolais bulls, respectively, were studied. Timed intervals during the calving process were compared between breed of sire groups. The Charolais sired calves required an average of 3.7 rain longer from the first appearance of the water bag until the feet were first visible; 8.1 rain longer (P<.01) from the t...

During December 2008 to January 2009, two persons contracted Legionnaires’ disease in a newly built block of flats in a suburb of Copenhagen in Denmark. Polymerase chain reaction and culture was used to diagnose Legionnaires’ disease in this cluster. Isolates from both patients tested positive for Legionella pneumophila serogroup 1 subgroup Philadelphia sequence type 1 and the same strain was d...

Though one dimensional self-gravitating N -body systems have been studied for three decade, the nature of relaxation was still unclear. There were inconsistent results about relaxation time; some initial state relaxed in the time scale T N t c , but another state did not relax even after T N 2 t c , where t c is the crossing time. The water-bag distribution was believed not to relax after T N 2...

mahallat hot springs located in the northeast of mahallat, in central iran. there are 6 main hot springs namely shafa, abejoush, donbeh, soleimanie, hakim and soda. in this research, geology, physico-chemical characteristics and petrography of basement rocks of these hot springs have been investigated. the results show that hot springs have an average temperature of 45°c and acidic to neutral p...

We report on a Q-switched VCSEL side-pumped 946 nm Nd:YAG laser that produces high average power blue light with high pulse energy after frequency doubling in BBO. The gain medium was water cooled and symmetrically pumped by three 1 kW 808 nm VCSEL pump modules. More than 1 W blue output was achieved at 210 Hz with 4.9 mJ pulse energy and at 340 Hz with 3.2 mJ pulse energy, with 42% and 36% sec...
