June 2011 plate tectonics and associated hazards Comment on the extent to which the features shown in the image support the theory of plate tectonics. To begin with we can see that many of the landmasses appear as separated jigsaw pieces with their complementary shaped coastlines. One example of this is how the North Western coastline of Africa could quite easily ‘slot into’ the North Eastern Coastline of America. This suggests that in the history of the Earth‚ these two land masses were once connected

Introduction A. Background of the study Due to the overwhelming demand of plastic bag production and its effects on our environment‚ our landfills are crammed with these non biodegradable materials. Substances used in the manufacturing brought forth various harmful chemicals which worsen over time. As the destructive compounds such as Chloroflourocarbon were introduced‚ the complete deprivation of the Ozone Layer starts. However‚ scientists and nature preservers alike managed to overthrow this

Rectal prolapse is painless protuberance of the rectum via the anus. Procidentia is complete prolapse of the entire viscosity of the rectum. Analysis is done by inspection. Ransient‚ minor prolapse of just the rectal mucosa often befalls in otherwise normal infants. Mucosal prolapse in grown-ups persists and might increasingly deteriorate. Procidentia is complete prolapse of the whole thickness of the rectum. The chief cause of procidentia is uncertain. Maximum patients are women above 60 years of

rigid convergent/divergent tube of known geometry for a range of steady flow rates. The Bernoulli’s theorem ( Bernoulli’s t heorem‚ 2011) relates the pressure‚velocity‚ and elevation in a moving fluid (liquid or gas)‚ the compressibility and viscosity(internal friction)of which are negligible and the flow of which is steady‚ or laminar. In order to demonstrate the Bernoulli’s theorem ‚ the F1-15 Bernoulli’s Apparatus Test Equipment isused in this experiment. The pressure difference taken is

Caffeine is a drug that is used to improve mental alertness by stimulating the central nervous system [1]. It is an ingredient found in a various amount of products sold on the market today‚ such as coffee‚ tea‚ chocolate‚ soft drinks‚ and energy drinks. Caffeine can be taken by mouth or intravenously (by IV) to help alleviate breathing problems in infants and can even be used in combination with some pain killers to treat migraines after epidural anesthesia. Moreover‚ it can be helpful in preventing

vascular resistance. The amount of blood pumped out of the heart is the cardiac output‚ and the sum of the resistance of all systemic blood vessels is equal to the total vascular resistance. An increase of blood volume‚ heart rate‚ stroke volume‚ blood viscosity‚ and peripheral resistance can all influence an increase in blood pressure. Any of these factors would increase the forces exerted upon arterial walls‚ which would cause the cardiovascular control center to respond with a decrease of sympathetic
