...What is a heat stroke? A heat stroke is a condition that starts with a fever and then usually by unconsciousness. This condition is caused by a failure in the body's temperature regulating mechanism when exposed to extremely hot weather. Before a heat stroke occurs people show signs of heat exhaustion such as dizziness, mental confusion, headaches and weakness but when a heat stroke happens when the person is asleep it may be harder for you to realize the symptoms. When young children have heat strokes some of the symptoms are different like the child may have a seizure, unconsciousness, organ failure and sometimes death. Between 1998 and 2011 at the very least 500 kids in the united states alone died from being in a hot car and 75% of them...

...A Review of the effect of fuel injection strategies on the performance and Emissions in HCCI engine Name: Institution: Keywords: HCCI engine, Fuel injection strategies, performance, emissions Introduction. Internal combustion (IC) engines have a wide range of application; therefore, reduction of emissions levels is an important design consideration [1]. Homogeneous charge compression ignition (HCCI) is as an attractive alternative that offers various advantages in internal combustion engines including the potential for significant reduction in PM and NOx as well as increased diesel efficiencies [2-4]. The HCCI technique involves the compression of a homogeneous mixture of fuel and air until auto-ignition occurs followed by Combustion that is considerably faster than Spark Ignition (SI) combustion [6]. The HCCI’s engine performance (including brake thermal efficiency, combustion phasing and emissions levels) is commonly predicted using numerical methods. Hairuddin et al [5] discuss the various strategies used in numerical method (such as multi zone and single zone models turbulence model and mixing model) and injection methods of predicting performance among other issues related to the HCCI engine. Various studies have shown that the can improve the thermal efficiency of the engine while simultaneously maintaining low levels of emissions and that HCCI technology can be realized by modifying either CI or SI engines using several fuel combinations [7,8].

...Acupuncture research in Cerebrovascular Accident induced hemiplegia. By Introduction to Cerebrovascular Accident and Hemiplegia Cerebrovascular Accident also known as stroke can broadly be described as an interruption of the blood supply to the brain. Without blood the brain cells are staved of oxygen, and can begin to die within minutes if the blood supply is completely cut off. It is this cellular death which has the greatest influence on the sequelae or after math of the stroke. Hemiplegia is the most common sequelae of stroke, this medical condition characterised by paralyses of one side of the body. It is similar to, but should not be confused with hemiparesis which is when one side of the body is weak but still mobile. While the leading cause of hemiplegia is a Cerebrovascular Accident, it is not the only cause, other neural conditions such as a unilateral pyramidal (UMN) lesion may also cause hemiplegia. It is difficult to discuss Hemiplegia without also discussing Stroke, similar to cause and effect, if stroke is the cause then hemiplegia is effect. A sudden stroke can be deadly, and how well someone recovers or if they recover depends largely on how fast they receive treatment. In Australia the most popular method for identifying stroke is the FAST test: * Face – Check their face. Has their mouth dropped? * Arms – Can they lift both arms? * Speech – Is their speech slurred? Do they understand you? * Time – Time is critical. If you see any of these...

...piston. It was steam at high pressure which was then used against the piston which was pushed and moved in a cylinder linearly. The engine piston was connected to a crank through connecting rod caused the crank to rotate about its axis. Thus rotary motion is generated. An engine would definitely need an expanding medium which will push the piston when expanding. The expanding medium will have to be at higher temperature and pressure. The heat required for increasing the temperature and pressure of expanding medium can be given to the medium outside the cylinder in which the piston moves. In such a case the engine is called external combustion engine. The steam engine and hot air engine are examples. Fuel is burnt out of engine and heat is supplied to working fluid which enters the cylinder of the engine with high energy due to temperature and pressure. In internal combustion engine the fuel is burnt in the cylinder in confined space between walls and top of the cylinder. The heat causes the gases, which become...

...THE IMPACT OF CLIMATE CHANGE ON THE UK HEALTH By Name Course Professor’s Name Institution State Date In the modern society, human practices influence the environment in a negative way. Specifically, industrial, agricultural and domestic activities exacerbate the ecological system, affecting humans, animals, and plants. Greenhouse emissions, agricultural chemicals, and domestic toxics cause air and water pollutions that affect human health. Therefore, climate change is an imperative factor that needs proper redress in protecting the health of the UK citizen. Accordingly, this paper examines the holistic health experience associated with climate change. Particularly, the paper explores climatic changes such as pollution and flooding and their direct influence in human health through infection and diseases. Climate change in the twenty-first century plays a vital role in the issue of public health. The rapid population growth rate of the modern world endangers human development and weakening the capacity of the contemporary communities to adapt and respond to climate change. The interrelation of population and climate changes lies in mitigation and adaptation. For this reason, people should reduce the levels of greenhouse emission and subsequently decrease the vulnerability of the population to the effects of climatic change. The science of climate changes integrates profoundly with the dynamics of the population. For example, the mass...

...music’s universality can affect the emotion. Therefore Patel discuss how the multiple mechanism theory states that music can enhance emotion in five different ways which are 1) expectancy and its fulfilment or violation, 2) activation of the brainstem by arousing acoustic features (e.g., sudden, sharp onsets); 3) association with past events; 4) visual imagery; or 5) acoustic cues that resemble the sounds of emotional voices. The two examples of biological power of music discuss by Patel in the reading are I recovery of brain functions after stroke II recovery of cerebral palsy in premature baby III recovery of verbal fluency in aphasia IV recovery of deaf due to exposure of high volume sound *a) I and III b) I and II c) II and III d) III and IV Easy-medium Source: Patel reading section 4 of the biological power of music: two examples Patel clearly discuss the two examples of music and the recovery of brain functions after stroke and music and recovery of verbal fluency in aphasia in both sections of 4.1 and 4.2. The lengthy discussions tell us how the music has a lasting effect on non-musical abilities. However the discussion by Patel only focuses on adults, however, children are the future generation and much more important because their developing brains can be shaped much more than adults. 1....

...Incineration as an Energy Source Author Institution Abstract This paper talks about incineration as a method of producing energy. The incineration sector in the country is also analyzed in the paper. The benefits that are associated with the method of incineration are outlined clearly and the costs and effects incurred as a result of incineration are also outlined. Incineration as an energy source; the pros and cons Incineration is a waste treatment technology that encompasses burning waste and transforming it into energy (Denilson et al., 1996). The wastes that are subjected to the process of burning can include residential, hazardous and commercial wastes (Denilson et al., 1996). The wastes are burnt in an incinerator which is a large furnace designed for that work. Incineration converts the materials deemed as wastes including paper, metals, plastics and food scraps into fly ash, bottom ash, combustion gases and heat (Denilson et al., 1996). In some instances the heat produced by incineration can be used to create electric power. In the United States there are a total of 113 incinerators that are working and out of these, 86 are used to produce electricity (Brebbia et al., 2014). The last incinerator in US was built in the year 1997 and ever since there has been no new incinerator built (Brebbia et al., 2014). The reasons for the halt in building incinerators in US was due to the public opposition regarding the costs of building, identified health risks and environmental...
