Alzheimer’s disease (AD) is a degenerative brain disease that involves dysfunctions and loss of nerve cells in central nervous system, was discovered by a German physician, Dr. Alois Alzheimer in 1907. As it is accounted for 50 to 75% of all cases of dementia, it is the most common form of dementia (Blennow et al., 2006) and it is known as a progressive neuropsychiatric disorder which involves memory loss, mood swing and loss of intellectual and social skills (Lee et al., 2010) and sufferer will progress through seven-stages of Alzheimer but with different rate (Reisberg et al., 2003). Prevalence of dementia increases exponentially with age from 60 to 85 years old or older, which is Senile plaques, neurofibrillary tangles, loss of synapses and degeneration of basal forebrain cholinergic neurons are the neuropathological hallmarks of this disease (Shen et al., 2005). It is a neurodegenerative disorder with unknown cause (Blennow et al., 2006). There are some hypotheses of pathogenesis of Alzheimer’... ... are able to interfere some metabolic pathways of choline metabolism. Hence, they have broad range on neurologic effects. From the experiment, monosubstituted 2-aminoethanols give the least inhibitory activity. There will be an increase in inhibitory activity when the degree of substitution and molecular size of the nitrogenous head of the molecule increase, due to the increase in the chance for van der Waals’ interaction with the protein surface, results in increased enzyme inhibition (Hartung, 1968). This complied with the principle of inhibitors with tertiary amino compounds act on PAS site. Enzyme inhibition occurs by steric blockade (Rosenberry et al., 1999) or allosteric activation (Auletta et al., 2010) will give low number of empty enzymes for further hydrolysis. Therefore, dialkylaminoflavonols shold be futher investigated in the discovery of better drugs.

A Gender Gap In Math Achievement Education Essay

Is There a Gender Gap in Math Achievement and How Can We Explain It?For many old ages the position has been that there exists great difference between the academic public presentation of between work forces and adult females, and particularly within the countries of scientific discipline and mathematics. This gender disparity in instruction within the US has been studied extensively by legion bookmans who have tried to detect if so there are unconditioned capablenesss in both sexes that make them hold differences in public presentation in scientific discipline and mathematics. The claims reported by Spelke ( 2005 ) are that few adult females show the endowments required in the Fieldss of scientific discipline and mathematics, hence there are fewer adult females within these Fieldss. The other position is that the sex differences in these Fieldss are due to the familial base which makes adult females have a smaller intrinsic attitude towards scientific discipline and mathematics. One such survey was carried out by Lawrence Summers when he was at the Harvard University. In his survey he tried to detect if there were any unconditioned capablenesss in both sexes that determined how they performed in both their faculty member and professional Fieldss in scientific discipline and technology. Apart from this research there are a many more researches that have been carried out to mensurate by how much or if there is any biological differences between the sexes that make them execute different in mathematics and scientific discipline. This paper shall discourse the being of the gender differences that drives the differences in public presentation in scientific discipline and mathematics of work forces and adult females. It is critical to understand the grounds why the difference in gender has been attributed to the cause in the differences in public presentation in scientific discipline and mathematics. This paper shall look into these differences that cut across all age groups, from the school traveling to the college pupils. It has been proposed that the differences that are seen in both adult females and work forces in public presentation in scientific discipline and mathematics have been associated with the differences in gender. Despite the progresss in the modern western universe there still exist strong societal cultural influences on perceptual experiences of gender and gender functions. Work force and adult females have been made to specify themselves on the footing of the distinguishable psychological and behavioural sensitivities that are associated with the biological maps. Therefore this sensitivity will drive work forces and adult females to act different, execute different undertaking s and do different picks. It is the definition of the individual in footings of maleness and women's rightist that drives them to act ad think as they do. With such thought in head, it becomes progressively hard to hold uniformity in public presentation in work forces and adult females at work and in faculty members. Marini, ( 2010 ) showed that so the greatest influence of this difference is the societal and cultural fluctuations that contribute to the sex differences. In her research biological differences do to some extent affect the behaviour and functions of the sexes, but it is the societal facets that have the greatest part to these differences. The societal structural agreement has made adult females and work forces base their thought and cognitive abilities on biological differences ( Baker & A ; Jones, 2006 ) . This so means that we are normally under the influence of our societal and cultural assignments that define who we are and what we can or can non make. The American society has defined and stratified the functions of the gender. It is this assignment of functions by the society that influences the grade to which the sexes addition and command the resources they have. Often our society has been specifying functions and responsibilities of the sexes based on gender class, for this ground gender differences exist within this society. The society has a strong influence on how work forces and adult females perform in scientific discipline and mathematics because it defines what function, responsibility or assignment is to be fulfilled by each ( Marini, 2010 ) . The adult male in society is superior to the adult females and is assigned tougher functions and responsibilities ; he is seen as the supplier, defender, more bright and has higher rational facets than the adult females ( West & A ; Zimmerman, 2007 ) . It is this societal facet that has given the adult male a male advantage and accordingly expected him to execute better at scientific discipline and mathematics. For this ground the instructors will handle male childs and misss otherwise in scientific discipline and mathematics categories. The ground being such countries of academic survey have been held as hard and ambitious, and merely the work forces can accomplish such feasts ( Baker & A ; Jones, 2006 ) . The instructor will so do the male child feel they need to execute good in these countries and will give their attending and resources to them. On the other manus the instructor will give the miss the perceptual experience that it is non incorrect for them to neglect in the topics, because the instructor does no anticipate them to execute good in these topics. Such positions are still woven elaborately in society where the society and the household influence the type of calling and profession work forces and adult females would take. In Marini ( 2010 ) , adult females are frequently encouraged to take up academic classs and topics that would take them in fostering callings of nursing, instruction and secretarial. Such callings and professions were seen as befitting adult females and give adult females a opportunity to take attention of her household. Mean while the Fieldss of scientific discipline and engineering are left to the work forces, this is because they are perceived to hold the rational capableness to manage the complex mathematics and advanced thoughts behind the Fieldss. It is being noted that there is increased diminution in the differences in scientific discipline and mathematics callings and professions between the genders as we find more adult females within these Fieldss. Recent research workers have shown that while the construction within the these Fieldss have changed with more adult females being found at the helm of such countries, there is still gender stratification in the high school degree, this can be found within surveies like ( Leahey & A ; Guo, 2001 ; Entwisle, Karl & A ; Olson, 2004 ; Spelke, 2005 ; Gallagher & A ; Kaufman, 2005 ; Baker & A ; Jones, 2006 ) . This difference in gender public presentation has been attributed to the perceptual experience that male childs and misss receive different attendings from their instructors in mathematics categories. This has created the gender spread within the academic Fieldss in America that have driven the differences in public presentation in scientific discipline and mathematics. The survey by Leahey and Guo ( 2001 ) tried to demo the extent of the gender differences in mathematics and particularly the different countries like geometry and logical thinking. It has been found that there is a male advantage for those pupils traveling to college within the field of mathematics. In their research they showed that males have a higher public presentation in mathematics in the high school degree and particularly in the college entryway test. The ground why this has been tested is because the high school mathematics has been the key to the pick in faculty members in the college degree and accordingly affects subsequently pick in profession. The ground why the American society has seen important differences in occupational segregation and gender socialisation in the populace sector is due to the gender differences in mathematics public presentation. In Leahey and Guo ( 2001 ) we find that this occupational segregation begins in high school mathematics where the scholastic aptitude trial ( SAT ) mathematics is performed better by male than the female. This is the same for the American College Test ( ACT ) mathematics subdivision that is performed better by the male. The same position is held by Entwisle, Karl and Olson ( 2004 ) , who have argued that the being of this disparity has been the cause of the differences within the callings and professional Fieldss. In their analysis it is the differences in the experiences of the male and female that is a beginning of the difference in public presentation in mathematics. The thought is that due to the school environment, male childs and misss will execute otherwise in these topics. They tried to demo this difference existed based on a comparing on simple as compared to the high school experience. In their survey they discovered that the experiences the male childs and misss had while in school affected their public presentation in mathematics. This experience was driven by the school environment where the instructors, disposal, parents and other pupils determine the public presentation in scientific discipline and mathematics. The pupils have been seen to be under the influence of their parents on the pick of topics, calling and accordingly public presentation. A parent who teaches their kids that they failed in scientific discipline and mathematics and hence does non anticipate the kids to make any better is a factor. Teachers who besides have biased positions towards misss and scientific discipline and mathematics besides drive down the public presentation of such misss. In the school state of affairs equal force per unit area is besides a major driver of public presentation in scientific discipline and mathematics. Entwisle, Karl and Olson ( 2004 ) merely showed that there were experiences from the school and vicinity resources that affected the development of mathematical accomplishments in the pupils. In their survey they revealed that there were contextual facets in the environment that affected the mathematical accomplishments in the male childs more than those in the misss. Male childs are able to react more to the resources in the vicinity than misss can, I the procedure they develop different accomplishments than the misss. Such accomplishments obtained from their milieus have been associated with the mathematical competence of male childs. The ground being that boys spend more of their clip in the vicinity than misss ; hence they are able to pull experience from their milieus than misss. This is because the society limits the geographic expedition capablenesss in misss while it encourages male childs to research more. This is the same position that is held by West & A ; Zimmerman, ( 2007 ) that shows that the Sociocultural facets influences male childs to research their environment more so the misss. Male childs are given the freedom to research and play around the vicinity, while misss were encouraged to remain at place. It is this geographic expedition that helps boys to develop better spatial and numerical abilities that see them execute better in mathematics. The experience within the vicinity and their milieus assist them farther develop their spacial accomplishments more than misss. Spatial accomplishments can merely develop if one is able to pattern them frequently, where the best country to make so is in the field. This difference in accomplishments is besides explained by Leahey and Guo ( 2001 ) , who showed that both misss and male childs have different mathematical accomplishments. Males have an advantage over misss in certain mathematical countries like their ability to quantitatively ground and do usage of spacial visual image abilities ( Gallagher & A ; Kaufman, 2005 ) . This same spacial accomplishments and concluding capablenesss are obtained by the male childs from their environment in which they are allowed to play in. since the misss do non hold the same equal playing field their logical thinking and spacial accomplishments are non good developed like those of the male childs. The same explains why males have better mathematical logical thinking and geometry accomplishments than misss. Leahey and Guo ( 2001 ) besides supported Entwisle, Karl and Olsonaa‚Â ¬a„?s ( 2004 ) theory with the determination that it is at the simple degree that these accomplishments are developed . The conducive factor is the socialisation procedure that the misss and male childs go through as they develop and learn at the simple age. Apart from socialisation the differences in mathematics public presentation has besides been associated with the cognitive differences in males and females. It has been argued that it is these cognitive differences that have enabled work forces to execute better at mathematics than adult females. Spelke ( 2005 ) associated this knowledge to the ability for work forces from the beginning to concentrate on objects that make them able to larn mechanical systems. As was seen by other surveies, Spelke ( 2005 ) besides supports that the spacial, concluding and numerical differences in work forces give them the ability to manage mathematical jobs. This is the 2nd factor that affects the cognitive differences between work forces and adult females. Another decisive factor is the variableness of the knowledge of males that give them that border needed in mathematics. It has been propose that the ground males perform better in mathematics is due to the sensitivity for them to larn about objects and the mechanical interactions in them from an early age. This sensitivity tends to do the adult females to switch towards larning about people and their emotional interactions. This interaction is seen more in ulterior life at the ages of school traveling kids instead than in babies ( Spelke, 2005 ) . This can be attributed to the socialisation of the kid that will do them levitate towards their gender assigned drama playthings and play subjects. Spelke ( 2005 ) proved that when speech production of the difference in knowledge there is no pronounced differences between babies. These disparities can be explained by the factors that are at drama when male childs and misss are developing. It is a complex state of affairs if knowledge is to be associated with the differences in mathematical public presentation of male childs and misss ( Gallagher & A ; Kaufman, 2005 ) . Given the same experience misss and male childs will get the same accomplishments and cognition in mathematics, demoing that knowledge and biological temperament has nil to make with the differences. This can merely be explained by Williams, Birke and Bendelow ( 2003 ) where the factors at drama are the implicit in interplay of biological capablenesss and environmental influences. This interplay of factors is the determiner of how the cognitive and accomplishments abilities in mathematics of work forces and adult females develop and accordingly differ. It is the society that has the greatest impact on the differences between male childs and misss public presentation in mathematics. The socialisation interactions of both male childs and misss are the ground why their cognitive abilities develop different signifier each other. Towards this terminal, Williams, Birke and Bendelow ( 2003 ) supports old surveies that have shown that the socialisation procedure is the predominate determiner of the differences in public presentation in mathematic. They have shown that there exist different interventions for both male childs and misss in our society from the place, school and workplace. In the procedure our gender is under the influence of civilization, where gender functions and responsibilities are defined by the same civilization. The position is that it is the societal statements that fuel scientific positions that so there are gender disparities in spacial and cognitive abilities of the sexes. Harmonizing to West and Zimmerman ( 2007 ) , it is the facet of work forces and adult females making gender functions and seeking to carry through gender that gives the differences in accomplishment in mathematics. The facet of seeking to be gender gives the work forces and adult females the ability to develop competences and recognize productivity that is based on the societal restraints. The societal construction thrusts worlds to hold a perceptual experience, interactions, and accomplishments that are based on societal complexnesss. This societal facet influences the unconscious determination by may adult females to go forth scientific discipline and mathematics callings and take up other Fieldss. Such societal complexnesss define how adult females and work forces perceive themselves in footings of their calling and professional development. The outlook of those who engage stop up in the Fieldss of scientific discipline and mathematics is that they have to set in more hours in the office, where they have to hold flexible agendas that can react to the eventualities of their occupations. Within his model, the callings in scientific discipline and mathematics will drive them to demo a continued attempt in their life rhythm, where the head is invariably working on jobs during and after working hours ( Summers, 2005 ) . The image promoted is that such callings drive work forces and adult females to demo a high degree of committedness to the work. For this ground, many work forces are ready to give this committedness with fewer adult females preferring to take up callings that can give them clip for the household. With such a perceptual experience in topographic point many misss wil l pay less attending to mathematics as compared to the male childs, giving the differences in public presentation ( Summers, 2005 ) . This societal perceptual experience of what one should anticipate if they follow a certain field has been one of the drive forces behind the differences in public presentation of work forces and adult females. Work force from an early age are expected to carry through their masculine functions as the suppliers and defenders. For this ground, the inclination is that work forces will take up callings and professions that can reflect this. Like was seen in West & A ; Zimmerman ( 2001 ) and Marini ( 2010 ) . These pigeonholing functions are still present in modern America and have been described extensively by Summers ( 2005 ) as the cause of the pick of callings by adult females. Such gender stereotyping besides influences how work forces and adult females perform in mathematics and scientific discipline. With a deficiency of involvement in scientific discipline and mathematics as a calling for the adult females, many will non set much attempt in these academic countries. Their involvem ent will be in the societal, linguistic communication and art faculty members where they excel and seek to hardly acquire a base on balls in the scientific discipline and mathematics countries. Often the society will wonder and inquire at adult females who excels in these Fieldss, with remarks to the consequence that she is tough being directed to her. It is the gender societal concepts that have shaped the perceptual experience of misss of scientific discipline and mathematics and have influenced their public presentation in these countries. As we develop our perceptual experience of gender is shaped by the society that defines who we are, what we can make. Therefore the differences in public presentation in male childs and misss mathematics and scientific discipline are under the influence of the societal cultural factors. These have in consequence created an environment where capablenesss and abilities are limited by the socially assigned gender functions.

Laban Movement

Christine Dugan Sheila Buttermore LMA Research Project Inner vs. Outer Connetivity Laban movement analysis is the language of dance and is considered to be sacred geometry that uses five crystallized forms that calculate movement and offers equations through symbols to make sense of everyday movement . By using laban motifs/symbols in an equation, the end product is almost always a dance or a deliberate movement sequence. The ability to use the laban system has made me aware of how I both observe and understand dancing in every sense of the word and idea of movement as I study as a performing arts major at Raritan Valley.The concept of inner vs. outer connectivity is what intrigues me the most so far out of they many interesting facts and ideas taught and spoken about within this semester taking into account that we were exposed to was only the tip of a giant ice berg that is LMA and all that it offers. The simple concept of thinking about, and emotionally feeling a movement and wher e that movement is intended to go through space before actually moving it is something I feel that I have been knowingly over analyzing in all of my years of dancing both in and out of class. Learning about inner vs. uter connectivity brought an awareness and a validity to my understanding of dance along with developing my ability to put inner states into outer expressions. In order to portray a specific emotion or gesture through movement, one must consider their Spatial Intent. â€Å"Spatial Intent is a clarity and specificity of outer destination in movement that has the effect of promoting and organizing inner connectivity†(1) For example, to execute a movement with a heavy intent such as stomping your feet on the ground, thinking of a heavy mass or emotion will allow that stomping to be perceived as an undeniably heavy, weighed action.When dancers have not been introduced to laban’s inner and outer connectivity concept, they are only achieving the technical aspect of the movements that they are taught, failing to connect with the inner dynamics that bring life and intent to performance. An example of how simply this can be taught to even the youngest of dancers would be to have them imagine that they are holding a beach ball in their arms, giving them a mental visualization of the correct placement of where their arms should be.By using laban’s method, this will eventually become an intrinsic component of their movements thereby developing muscle memory and natural inner and outer connectivity. Within one of the books that assisted me throughout my research, â€Å"Body Movement: Coping With The Environment† it states, â€Å" When, however, a specific spatial intent is added, such as a gathering movement of embracing or a scattering movement of repelling particular objects, a new tension is created between the object and the initiation of the movement in the body, and a particular, rather than a general, spatial shape is produc ed as the movement proceeds. (2) This book was a collaboration of Irmgard Bartenieff, the man who created the basic six exercise’s and the BF principals taught in LMA and Dori Lewis from the 19th century. This along with several other quotes and passages once again validated my original thoughts on the simplicity and efficiency of these methods for teaching and ways of thinking of movement. Aside from form and spatial points as well as technique being what makes dance, emotion comes first in order to authenticate and embody what that dance really means to you.Without emotion and purpose behind a dance, there is no inner connectivity to transcend out onto those watching you move. It is not hard to tell the difference between watching a dancer who is committed and invested in the movements they are making from head to toe and seeing the purposeful look in their eyes as they follow the direction they are moving, compared to a dancer who seems to appear somewhat jumbled up in the ir movement, displaying lack of directional intent and body connectivity with a blank look on their face and without emotion in their eyes.Audiences universally go to see performances with the intention of having an emotional experience whether it be happy, sad, funny, ect. It is up to the performers to fulfill those expectations. It is through the skill and inner and outer connectivity of the performers that these expectations can be met. It is with the knowledge that I have gained through learning about Laban’s theories and concepts that will allow me to have a new level of awareness and sense of connection.I will apply what I have learned with a conscious effort to implement my body connectivity both inner and outer as well as how I portray my movements as I go forward in dance. Studying Laban theories and concepts has given me a deeper appreciation of both performance and everyday movement. I look forward to continuing my understanding of this amazing language of dance th at was created by Rudolph Laban, who made an intangible art from, tangible.

Strikes in the Early 1930’s

Strikes were common place in the early 1930†³s in all industrial and manufacturing corporations. They were used to win power away from the corporate giants, and put it in the hands of the working class. Labor used strikes for a variety of reasons, some for higher wages, some for working conditions, some for safety on the job, and still others for recognition. In a book entitled, â€Å"I Remember Like Today: The Auto-Lite Strike of 1934† Philip A. Korth and Margaret R. Beegle compile an oral history account of this fight for the rights of the working class. To gain the knowledge acquired for this book, the authors searched high and low to ind the living survivors of this turning point for organized labor in Toledo. After discovering the individuals who could help, the investigators interviewed and then recorded the men and women†s accounts of the strike. Then they transcribed the interviews verbatim. This method provides for a more personal approach to learning what had happened in the strike. It allows the reader to see what actually happen through the The book is a collection statements, stories, and feelings of the men and women involved in the strike. Each individual tells their story based on headings, and that is what complied the chapters. In this method, the reader gets to hear all sides of the story because Korth and Beegle get some who were union supports, union organizers, some who were strike breakers, management. Certainly no critic can say, this book only tells one All of the forth-coming events, activities, and problems took place in Toledo, Ohio at the Electric Auto-Lite Company. The Electric Auto-Lite Company was a part of the automotive assembly industry. It used mainly unskilled workers to operate the machinery, and the machinery was that There were two separate strikes at Auto-Lite. The first was used to orce the company into recognizing the union; that was the first step towards collective bargaining†¦ recognition. It stared on February 23, lasted only four days, and resulted in the reinstatement of the 15 workers who walked out, and an agreement. The workers won the battle but that was a long way from winning the war. Auto-Lite gave the union a 30-day contract, which basically stated the company would recognize the union for thirty days, but even in that thirty days the company refused to recognize the union as a bargaining representative of the workers. When this thirty ays reached its conclusion, the union was no better off then when it started. In fact in those thirty days the company was preparing itself for a strike. They started mass hiring new workers, so they could keep running the company if the labor walked out. The second strike began on April 13, and consisted of some 400 Auto-Lite workers. The strike seemingly divided the work force equally, as many went in as picketed. Then on May 3, a court injunction restricted the number of picketers at one time to a minuscule twenty-five. This rallied the surrounding men and women in the area to unite and break this injunction hat limited all of their freedom. On May 21, 22, and 23 more then 6,000 men and women united in front of Auto-Lite to hear speakers and to protest the company, along with protesting the court injunction. This is when the real trouble started for the company and the picketers. On May 23, A young women by the name of Alma Hand was stuck by a steel bracket which caused a riot among the crowd, and which initiated a raid on the building. The deputies fired tear gas at the would be invaders to stop them from storming the facility. That night a raging crowd refused to allow the scabs off the premises. After this episode, the Ohio National Guard was called in to restore the peace. These guardsmen only worsened the situation. On the next day, May 24, they charged the crowd wounding 12, then firing their rifles and killing one, then later that same day, they fired once again wounding two more picketers. By the 26th of May, with demands that the plant be closed and the Guard withdraw, another tragic confrontation occurred. The crowd attacked the Guard, 200 were injured and 50 were arrested. The plant remained closed for the following week and did not reopen until June 5. At this point, the strikers had emerged victorious. After all the hardships, injuries, and deaths, the union had been established and recognized. This was a shallow victory at first due to a number of circumstances. First of all, the old workers who remained at work throughout the strike had preference during the rehiring process. Secondly, betrayers who associated themselves with management formed their own bargaining organization called the Auto-Lite Council. This organization acquired for them preference in rehiring. The Auto-Lite Council soon diminished in numbers, while Local 18384 was increasing dramatically. This was due to the realization that the strikers were the ones who had won them collective bargaining, not the Auto-Lite Council. Therefore, their loyalties lied with the organization that had created the situation in which they had more power, respect, and The Auto-Lite strike is a perfect example of how the labor movement has advanced. The first strike only involved a mediocre 15 men. The second strike reached out to about 50% of the work force. The men and women of Auto-Lite had embraced their union and made it their own. This represents the labor movement because at the start only about million workers were unionized. At the pinnacle of the movement nearly 50% of the work force was organized, the number was in excess of 10 million individuals. Workers saw how the union could help them. They saw solidarity and unity, which when combined produced a force to be reckoned with. The union provided for higher wages, more benefits, and better working conditions. This idea is what attracted more members and this belief is what united the men and women at Auto-Lite. The strike also represents the risks and hardships accepted by the organizers who take on the challenge of forming a union. The 15 who went out in the first Auto-Lite strike took the chance of losing their jobs and hampering their families welfare to form a union just to help every worker in the plant. The men also accepted that they were going to lose their jobs and would have to fight for reinstatement. But all the risks taken, and all the brief hardships felt were well worth it considering the ends. Their union was recognized. Not to the extent they wished, but nonetheless they won recognition, which catapulted them to eventual complete victory. This result was not always the case. In some strikes the union failed nd the workers lost big. To the credit of the workers, their supporters, and their organizers the men and women of Auto-Lite were triumphant and won the fight of all fights; to gain respect, power, and recognition. This event was the turning point in labor relations in the city of Toledo. It gave confindence and self worth to the working class, and stripped the company management of their unimpeded omnipotence. The Auto-Lite Strike of 1934 changed the entire way that company operations were run, and for that, those who work in Toledo should be applauded, and recognized for the achievements they accomplished.

Toxic Hazard and Risk of Lead for Consumers Essay

Toxic Hazard and Risk of Lead for Consumers - Essay Example Lead is a highly toxic substance which when ingested may lead to irreparable neurological damage in children (ATSDR, 1999), kidney diseases, cardiovascular problems and reproductive complications. In 2007 Lead was ranked as the second most toxic substance after Arsenic (ATSDR, 2007). The toxicology of Lead is a result of its chemical similarity with Calcium thus the human body confuses Lead for Calcium and incorporates it into the bone marrow, kidney and the brain. Inasmuch as Lead affects adults, its effects on children can be fatal. A minimum of 10g/ml blood Lead impairs mental and physical development in children. A maximum of 80g/ml blood Lead leads to convulsions, comma and death. Lead poisoning can be detected through a number of symptoms. In children, the symptoms include abdominal pain, anaemia, vomiting, weight loss, short concentration span, hyperactivity, petulance and a slow speech development. In adults, the symptoms may include abdominal pain, memory loss, pale skin, weight loss, vomiting, petulance and anaemia. Lead poisoning can come from a number of exposure routes. All students, faculty staff and all visitors in IUB are exposed to these routes. First, the exposure route involving Lead Based Paint (LBP) is a major source. The paints used IUB buildings may chip off due to wear and tear, moisture friction or deliberate removal during renovation. The chips contain lead and mix with the dust which can be inhaled. The chips in the soil may leech and end up in water bodies. This route is not an acute exposure route. It is only acute to children who are fond of mouthing non food objects and substances. The preventive action to avert this exposure is to use Non- Lead paints which are of the same quality and glaze just like LBP. Industrial/ occupational Lead exposure is another possible route in that workers in a factory or laboratory that handles Lead are exposed to lead. Examples of such workers in IUB are those in pottery (Use Lead glaze), automotive repair (inhale exhaust fumes with Lead), industrial machinery and equipment, (inhale exhaust fumes with Lead) and chemistry students/laboratory technicians (analyze LBP or even handle elemental lead). Students of ceramics who use Lead glaze may inhale the Lead fumes involved in the Lead glaze. Those individuals threatened by this kind of exposure need to be careful and keen to wear protective gear such as masks to prevent the inhalation of the Lead fumes. This exposure is an acute threat because of the form and amount of Lead inhaled. The amount inhaled can be specifically high because the Lead is in gaseous form. Dishware is another exposure route. The plates and cups made of melamine or glass with a lead glaze, used by the students and faculty at the cafeteria or any other eating place, are a real threat. This is so because acidic food (such as tomato sauce, coffee, juice etc) kept in these containers may exacerbate lead leeching which can lead to lead poisoning. Though this is not an acute threat based on the amount of lead that can possibly leech, it is important that any dishware with a lead glaze is avoided. Most

Federalism and the Exercise of National Power Coursework

Federalism and the Exercise of National Power - Coursework Example Similarly, regulating the use of marijuana is not spelled under the commerce clause. Taking away homegrown marijuana is a way of controlling its consumption. There is no law in the US constitution, which gives federal government powers to invoke cultivation of marijuana without explanation (Pierre, 2011). Therefore, Commerce Clause or other clauses do not grant the federal powers to regulate the use of marijuana. The federal system overstepped its mandate to ban marijuana. This is so because the 10th Amendments state that the people have a say on powers that the constitution does not delegate to the United States (Pierre, 2011). Thus, the cultivation of marijuana is not spelled in the constitution leaving the decision to lie with the individuals and the state. Similarly, growing marijuana for medical purposes is allowed as long as it is not for commercial purpose under Commerce Clause. Moreover, the federal government has powers to regulate interstate commerce under Article 1, Section 8 of US constitution (Pierre, 2011). However, this does not mean they have powers to control anything associated with interstate commerce. The woman who grew marijuana was an exception because there was no evidence of participation in interstate
