Geothermal Energy Essay - 1270 Words

Geothermal Energy In todays world, we are stuck in a constant debate about efficient energy usage and production. Many have gone to alternative fuel sources do to the rising cost of fossil fuels and the environmental damage caused by the burning of fossil fuels. One option that goes largely unexplored is geothermal energy. Geothermal energy is not only a much more environmentally-friendly power source than fossil fuels, but the cost of installation is not significantly more expensive than the installation of a new â€Å"High Efficiency† conventional heating system. The focus of this inquiry will be upon single-household use, however it will also delve into geothermal energy on an industrial scale. The first question any reasonable homeowner†¦show more content†¦After this point you will continue to save the $2617 per year. Based on Jay Eggs professional calculations, you will save $31,855 over the course of 15 years over installing a new â€Å"High Efficiency† conventional system, and $9,885 without factoring the cost of a new high efficiency system. Another question homeowners generally ask is: Where do these costs come from? The majority of the costs of installing a closed loop subsoil geothermal system in your household come from the cost of drilling the bore holes and running the piping. Costs, which while not factored in to the above equation, may be reduced due to your specific location (Next to a large body of water, likely meaning the presence of an aquifer beneath the Earth below your house.) In your home, depending upon the presence of an aquifer or the ability to place piping into the lake, you may opt instead to use an open or closed loop system that runs either through the lake in pipes (closed loop) or into and out of an underground aquifer through two pipes, using free standing water as the heat exchange medium (open-loop system). The costs of these systems are typically lessShow MoreRelatedGeothermal Energy And Natural Ene rgy1118 Words   |  5 Pagesvery hot pools, known as geothermal reservoirs.

The Development of Attachment Essay - 793 Words

The Development of Attachment Psychological research can inform us about the development of attachments to a certain extent. Mary Ainsworth actually covered a definition explaining, how we know when an attachment has developed. This is; the infant tries to get close to and maintain that proximity with the caregiver, using a number of strategies to do so. E.g. clinging and signalling behaviours such as smiling, crying and calling. The fact she has outlined this definition obviously shows she must have evidence to back her definition up. John Bowlbys view on attachment is that it is very important to ensure the survival of infants. Attachment must be two-way in order to ensure good care. The†¦show more content†¦However, the friendly responses to other people decrease and the infant treats strangers with increasing caution, (stranger anxiety). Schaffer and Emerson (1964) responded to some of Bowlbys earlier research by conducting a longitudinal study of sixty infants who came from working-class homes in Glasgow. The infants were observed over a period of one year in their home. This study has high ecological validity as the surroundings the mother and infant were in were true to life. Most infants showed separation protest at seven months, which indicated a specific attachment to one person. Within one month after the investigation, 29% formed multiple attachments and 78% formed multiple attachments within six months of the first specific attachment. In 39% of the cases, infants did not show their first specific attachment to the person who fed or bathed them. Responsiveness appears to be the key to attachment. Intensely attached infants had mothers who responded quickly to their demands and who offered the infant the most interaction. Infants who were weakly attached have mothers who failed to interact. They then produced their own stage theory consisting of three distinctive stages. The Asocial stage (0-6 weeks)- emotional behaviour such as smiling and crying does not seem to be directed specifically at any given individual.

Marijuanas Short and Long Term Effects On The Bra Essay Example For Students

Marijuanas Short and Long Term Effects On The Bra Essay inMARIJUANAS SHORT AND LONG TERM EFFECTS ON THE BRAIN Millions are abusing marijuana every day. In fact, 1 out of 7 high school students smokemarijuana more than once a day. Marijuana is taken very lightly and is the most highly usedillegal drug. For this reason, society should know its short and long term effects on the brain. Marijuana can effect these two areas emotionally or physically. Also in some cases physical damages causes the emotional response. Although most public information on drugs are funded by anti-drug organizations, hopefully we will still learn these true facts of marijuana in spite of that. The brain is the most complicated part of the human body. I will begin explaining certainparts and their functions. In doing this to I hope to give a better understand of our brain while implicating the possibilities of chemical induced complications The brain with its 15 billion neurons and nerve cells operates using chemical and electrical messages: (Swanson, 1975). This is how we perceive our senses. Differences in the way our brain translates these messages can impair perceptions. Hallucinogens prevent the brain from receiving all of these messages in order. All of the information that we receive is through millions of transactions of neurons, like a computer, marijuana alters these transactions. After smoking, or consuming marijuana, it is distributed in the brain. The concentration of marijuana in the brain may be governed by an active transport process in the choroid plexus network of blood vessels in the brain which regulates intraventricular pressure by absorption and secretion of cerebro spinal fluid. one scientific experiment it gave an example of how the distribution of marijuana in the central nervous system could effect man. At a high dose of 30 mg./kg. marked sedation and pronounced motor incoordination peaked at the one hour interval subsiding in 8 hours when over reaction occurred to external stimuli; man reveals incapacitation of cognitive and motor function. High concentrations of marijuana are usually found in the following parts of the brain: the frontal cortex (the general association area), and hippocampus (short term memory and oreintation). As a result, perception of time, mood and general cordination is impaired. It is apparent that marijuana intoxication effects the neurological functions and usually disappears in 24 hours, but can become a permanent malfunction. THC effects the limbic system which is vital to some every day functions. The brain is made up of 3 basic cerebral types differing in structure, chemistry and organization (MacLean, 1970). These are: 1) reptilian or brain stem responsible for instinctive (survival) behavior (and regulator of vital functions of the body) 2) old mammalian (paleocortex) or limbic brain surrounding the brain stem (like a lap or limbus) having an important role in emotional behavior and motivation (contains opiate receptors) 3) new mammailian (neo cortex) brain (thinking cap) with the capacity for symbolic (written and spoken language). The 3 subdivisions of the limbic cortical system or ring are linked by 3 pathways to the brain stem. The lower part (hippocampusi memory information) of the ring connected with the amygdala insures self-presentation (survival). The upper part is connected to the septum which is the area for pleasure. These 2 are connected to the olfactory which deals with sense. In addition, there is a third passageway dealing with sexual behaviors and visual activities. Any limbic dysfunction can result in emotional and mood disturbences alienation distortions of perceptions and paranoid states. THC can reduce the blood flow to the hippocampus, which earlier I introduced as the controller of short term memory and orientation. To make a simple conclusion to all of this confusing data, marijuana results in chemical damage effecting emotional, motivational and hormonal disturbances. After 3 months of light, moderate and heavy use, evidence of irreversible damage can be detected. The effects of marijuana are mostly short term. When I say short term, I mean damages that can restore to normal. Most symptoms from heavy usage vanish in about a year and a half of clean time. Although, not ever exactly back to normal relatively emotional and memory abnormalites are restored. Justifiable Homicide At The Hands Of The State Essay Effects physically and mentally are also recorded Tolerance to a drug develops when increasing doses are necessary to obtain the initial effect of a lower dose. Dependence may be psycholgical and/or physical. Psychological dependence refers to a craving for a drug often leading to complusive drug use. Physical or physiological dependence is a state whereby withdrawal of the drug leads to undesirable effects in mood or the physical body. I will first explain the most common tolerance with THC. Marijuana is used to experience a high and as a person continually introduces this chemical into the body, it grows accustom to it. Hence, in order to get the same high you must smoke more potent marijuana. Cells in the pleasure center of the brain are being damaged and as more are damaged, more marijuana is needed. Also, the natural high is harder to achieve. In regard to dependence and addiction there is still much controversy. Most is on the exact definition, not about marijuana at all. Is it to need the drug and obtain it by any means? Tolerance? Or simply any mental or physical dependence? The facts are that marijuana is definitely mentally addictive and possibly slightly physically addictive. Marijuana releases dopamine causing pleasure making the user most likely want to feel the same way again. One argument W. Paton, Every day I wake up and eat Kelloggs corn flakes because I like corn flakes. Does that mean I am addicted to corn flakes? Others believe that since it triggers dopamine in the brain it must be addictive. Long term damages due to marijuana are noted. Marijuana seems to have some irreversible effects, but it is difficult to prove that marijuana was the cause. The thing holding up most scientist is the question of marijuana physically effecting the brain. Many studies show that it does, but most times there are too many uncontrollable factors. Monkeys are usually used and they relate this to humans. Such as in this experiment, after having the monkey smoke marijuana for 5 months, then letting it be clean for 3 months, then see if there is differences. Abnormalities include (RER) chaos and synaptic vesicles. RER or rough endoplasmic reticulum makes proteins so that the cell can function properly. RER is in neat strands in the cells interior. But, in heavy smoking monkeys there was chaos. Synaptic vesicle activity accounts for our thinking, feeling and doing. Heavy smoking monkeys had synaptic vesicles that were clumped together. The vesticles were also filled with abnormal deposits of material. The conclusion was that this could cause the symptoms of a marijuana abused brain. Those symptoms are bad short term memory, apathy, lack of motivation and depression. Most findings do conclude after smoking marijuana for periods of time cause them afterwords to be disconnected from social activities and have noticeable differences in memory. But, most surveys or studies dont usually ask the marijuana smoker to be clean for a year. This would probably prove more of the long term effects. It is somewhat disturbing that with all of the new technology, we cannot exactly prove that marijuana has long term effects. Short term effects have been pretty much proven. Millions are abusing marijuana every day. In fact, 1 out of 7 high school students smokemarijuana more than once a day. Marijuana is taken very lightly and is the most highly usedillegal drug. For this reason, society should know its short and long term effects on the brain. Marijuana can effect these two areas emotionally or physically.
