Entrainment

between the fire floor and atmospheric pressure is larger than at the lower place of the vents. At the bottom of the vents, the pressure difference becomes negative to that at the top. So there should be neutral pressure plane or zero-velocity plane α and β at the two vents respectively. At the early stage, the pressure, temperature & density of the air in the atrium (Pa, Ta, ρa) are almost the same with those outside (P0, T0, ρ0), so the flow at the two vents are almost the same. Plane α and β are almost at the same vertical position. At vent WA, along with the smoke flowing into the atrium, high temperature smoke in the atrium being more and more and flows up to the ceiling of the atrium, the air in the atrium reduces due to the entrainment by the rising plume and supplying to the 1st floor, and atrium pressure Pa decreases, too. It results that the volume of air entering the fire floor from the atrium is decreases, the amount of smoke entering the atrium is more and the vertical position of plane α decreases till it reaches the sill of WA. At vent WB, the ambient temperature and pressure (P0, T0) will be the same value during the fire, so WB flow is mainly depend on WA flow. The amount of air which is flowing in the fire floor through WB will increase if the amount of smoke which is flowing in the atrium through WA increases because of continuity of flow, and decreasing of the outflow of smoke at WB. The β vertical position will rise till the bottom of WB. When α and…

temperature. The next fresh property recorded was the unit weight. There was not enough concrete left after forming cylinders to measure unit weight, but if there was if would be done in the following manner. The metal container used for the air entrainment testing was used for the unit weight. Concrete was placed in the measure with proper packing protocol (fill one third the way, tap twenty five times, repeat) and excess concrete was stuck of the top. A weight measurement was then taken. This…

Functional MRI studies have shown that musical training increases brain responses in an auditory–motor synchronization network. In three magnetoencephalography (MEG) experiments by Keith B. Doelling and David Poeppel of New York University, nonmusicians and musicians with varying experience levels were played music at various tempos to map brain activity. The MEG records magnetic fields that are produced by naturally occurring electrical currents in the brain. The MEG readings from nonmusicians…

treatment would be beneficial for advancing sucking skills. In a study conducted by Barlow et al. (2008), it was found that preterm infants with RDS had differing fine structures of NNS pressure amplitude compared to healthy preterm infants. These findings are useful because they enabled the researchers to draw conclusions on ways to enhance infant’s maturation of specific sucking skills. Assessing and administering treatment in a timely manner allows for a more successful recovery rate and a…

induces circadian clock and behavioral cycle misalignment in order to evaluate metabolic, autonomic, and endocrine function. The study population consisted of 10 adult subjects, 5 of which are female. A comprehensive medical examination was conducted prior to the study to ensure the subjects were healthy with no significant medical conditions. The investigators first established a stable baseline of circadian phase angle entrainment by having subjects “maintain a regular sleep-wake schedule for…

nerve pain. Under arousal of particular areas of the brain, on the other hand, results in other types of depression, insomnia, chronic pain, and attention deficit. When researchers find instability in the brain rhythms, they are bound to conclude that the individual is susceptible to explosive behavior, hypoglycaemia, diabetes, bulimia and anorexia, vertigo, sleep apnea, epilepsy, bipolar disorder, panic attacks, or aggressive behavior. It is thus possible for one to alter their brainwaves…

Discussion Vascular air embolism is the entrainment of air (or exogenously delivered gas) from the operative field or other communication with the environment into the venous or arterial vasculature, producing systemic effects.[2] Air embolism can result from procedures performed in almost all clinical specialties and is mostly encountered during neurosurgical procedures in sitting position, the veins of the throat during surgeries on neck, and in some cases veins in the coagulated operative…

characterized by socially undesirable behavior, as poorcontrol of impulses or inability to maintain close emotional relationships, and by absence of anxiety or guilt. Dick showed the absence of guilt by not feeling remorseful of the murder .He is motivated by lust, greed, and indulgence of any kind. He is the mastermind behind the murder. His desire for greed motivated him to go to the clutter ranch because he heard they had a lot of money. His desire for lust motivated him to go to the ranch by…

On March 1st, 2016, the CEE 3030 Construction Materials class mixed concrete with varying water cement ratios and created three, 3” diameter by 6” high cylinders and three, 6” diameter by 12” high cylinders. The cylinders were cast according to the ASTM C31 standard. The class was divided into sections, then the sections were divided into teams. The sections mirrored each other, and teams created concrete with 0.40, 0.44, 0.48, and 0.52 water cement ratio. Over the next 28 days the cylinders…

groups. 662 mobile phone users aged 18-68 responded to the survey. The participants in the study felt text messaging is more appropriate than calling in all situations, expect for driving. Men generally believe that calling is more approiate than women, and there were no age differences in the belief of appropriateness of calling in the variety of settings. The younger group in the study believed that text messaging was a more appropriate method of cell phone use. Wei (2008) sought to gain more…
