Porfiero Diaz essays

Porfiero Diaz essays Jos de la Cruz Porfirio DÃ ­az (15 September 1830 2 July 1915) was a dictator who ruled Mexico from 1876 until 1911 (with the exception of one single four-year period). Diaz was born in the city of Oaxaca, Mexico. He was a Mestizo, of Mixtec Indian and Spanish ancestry. An army officer with humble rural roots, he became something of a hero due to his participation in the war against the French, where he won several important victories. He led the cavalry in the celebrated Battle of Puebla of 1862. In 1876, he overthrew the government of President Sebastin Lerdo de Tejada. Initially, he advanced a platform of reform, using the slogan "No Re-election" (for the President). Defeated by Juarez in the presidential election of 1871, Diaz charged fraud and led a revolt against the government, which was not suppressed until after the inauguration of Sebastian Lerdo de Tejada. Diaz again lost in the presidential race of 1876. He refused defeat and 1876 he overthrew the government of President Sebastian Lerdo de Tejada. Aside from a brief period from 1880 to 1884 when he handpicked Manuel Gonzalez as his temporary successor, he remained in power until 1911. His rule was ruthless and ultimately effective. He maintained power through manipulation of votes, but also through simple violence and assassination of his opponents, which as a result were very few. He was a cunning politician and knew very well how to manipulate people to his advantage. He also sought reconciliation with previously hostile sectors, particularly the Catholic Church and the U.S. government. Diazs policy encouraging foreign investment resolved U.S. interference with Mexicos decisions, and led to U.S. recognition of his regime. Diaz embarked on a program of modernization, attempting to bring Mexico up to the level of a modern state. His principal adviser ...

The Diurnal Cycle and How it Affects Daily Temperatures

The Diurnal Cycle and How it Affects Daily Temperatures All things in nature have a diurnal or daily pattern simply because they change throughout the course of a day. In meteorology, the term diurnal most often refers to the change of temperature from the daytime high to the nighttime low. Why Highs Dont Happen at High Noon The process of reaching a daily high (or low) temperature is a gradual one. It begins each morning when the Sun rises and its rays extend toward and strike the Earths surface. Solar radiation directly heats the ground, but because of lands high heat capacity (ability to store heat), the ground doesnt immediately warm. Just as a pot of cold water must first warm before coming to a boil, so must the land absorb a certain amount of heat before its temperature rises. As the grounds temperature warms, it heats a shallow layer of air directly above it by conduction. This thin layer of air, in turn, heats the column of cool air above it. Meanwhile, the Sun continues its trek across the sky. At high noon, when it reaches its peak height and is directly overhead, sunlight is at its most concentrated strength. However, because the ground and air must first store heat before radiating it to surrounding areas, maximum air temperature isnt yet reached. It actually lags this period of maximum solar heating by several hours! Only when the amount of incoming solar radiation equals the amount of outgoing radiation does the daily high temperature occur. The time of day this generally happens depends on a number of things (including geographic location and time of year) but is usually between the hours of 3-5 p.m. local time. After noon, the Sun begins its retreat across the sky. From now until sunset, the intensity of incoming solar radiation continually declines. When more heat energy is being lost to space than is incoming at the surface, a minimum temperature is reached. 30 F of (Temperature) Separation On any given day, the temperature swing from low and high temperature is roughly 20 to 30 F. A number of conditions can widen or lessen this range, such as: Day length. The greater (or shorter) the number of daylight hours, the more (or less) time the Earth is subject to heating. Length of daylight hours is determined by geographic location as well as season.Cloudiness. Clouds are good at both absorbing and giving off longwave radiation, and at reflecting shortwave radiation (sunlight). On cloudy days, the ground is shielded from incoming solar radiation because this energy is reflected back out into space. Less incoming heat means less and a decrease in diurnal temperature variation. On cloudy nights, diurnal range is also decreased, but for opposite reasons heat is trapped near the ground, which allows the days temperatures to remain constant rather than to cool.Elevation. Because mountain areas are located farther from the radiating heat source (the sun-heated surface), they are warmed less and also cool more rapidly after sunset than do valleys.Humidity. Water vapor is good at absorbing and giving off longwave radiation (energy tha ts released from the Earth) as well as absorbing in the near-infrared part of solar radiation, which reduces the amount of daytime energy reaching the surface. Because of this, daily highs are typically lower in humid environments than they are in dry environments. This is the primary reason why desert regions experience some of the most extreme day-to-night temperature fluctuations. Wind speed. Winds cause air at different levels of the atmosphere to mix. This mixing lessens the difference in temperature between warmer and cooler air, thus decreasing the diurnal temperature range. How to See the Diurnal Pulse In addition to feeling the diurnal cycle (which is done easily enough by enjoying a day outside), its also possible to visibly detect it. Watch a global infrared satellite loop closely. Do you notice the curtain of dark to light that rhythmically sweeps across the screen? Thats Earths diurnal pulse! Diurnal temperature isnt just essential to understanding how we meet our high and low air temperatures, its essential to the science of winemaking.

Emotional Intelligence and Emotional Competence Research Paper

Emotional Intelligence and Emotional Competence - Research Paper Example Saarni states that an emotionally competent person is able to perform according to his moral values in â€Å"emotion-eliciting† situations that demand his â€Å"self-efficacy† (1999, p.2). Such a person is aware of his emotional state and of others and is able to work accordingly. Comparison and Contrast EI improves our ability to learn EC. The two concepts cannot be separates. Scholars define EC as a learned ability of an individual resulting from EI which enables him to show outstanding performance in every field of life and, more specifically, job. For example, to show skill in conflict resolution with customers, it is important that the individual knows EI basics like relationship management. However, if he has mastered in EI basics like relationship management, that that does not guarantee that he has also mastered in conflict resolution. He has only gained potential to learn EC by learning EI. To make a contrast, EI involves tackling emotional situations in all wa lks of life while EIs are specially job skills based on EI.

Should prisoners be given the right to vote in UK Essay

Should prisoners be given the right to vote in UK - Essay Example Having the status prisoner on an individual’s bio does not help their chances of integrating into the community and tends to lock them out of most of the privileges that are enjoyed by the rest of the society. At the moment this also includes voting opportunities that are available to others as that privilege is revoked by the government (Lynch, 2007). However, the question remains of whether this is an ethically acceptable arrangement or is change needed in this department in the long run to improve the democratic movement that is supported by a large majority of people. In order to study this question and come up with an acceptable response it is important for one to look at all the perspectives that views that are involved when it comes to the issue of allowing prisoners to vote. Other aspects of the subject that should be studied include the various parties that are involved in the making of this decision as well as those that are affected by it. These include the legislators and (depending on various factors, such as whether a referendum is held on the matter) at times the public opinion on the side of those involved in forming of the concerned laws and the prisoners as well as society on the side of those who will be affected by the decision made (Harel, 2008). This is essential as making a right decision depends on knowing all the factors involved as well as the potential impact that certain decisions will have in the long run. It should be noted that the voting process is part of the democratic setup that was developed to ensure the presence of fairness and equality to all citizens (Ross, 2011). As afore mentioned, taking a closer look at the main groups that are involved and affected by the final decision on whether prisoners should be allowed to vote will allow one to come up with a more overall view of the situation and various circumstances involved. They include: These are the main group of people that are

Goals of Financial Management Essay Example for Free

Goals of Financial Management Essay Money required for carrying out business activities is called business finance. Almost all business activities require some finance. Finance is needed : †¢To establish a business , †¢To run it †¢To modernize it †¢To expand it or diversify †¢It is required to buy whole variety of assets, they may be tangible like machinery ,factories,building,offices or intangible like patents, technical expertise etc. Success of business depends considerably on how well the funds are deployed in assets Financial management is concerned with optimum procurement as well as usage of finance. The financial management has to take three important decision viz. (i) Investment decision i. e. , where to invest fund and in what amount, (ii) Financing decision i. e. , from where to raise funds and in what amount, and (iii) Dividend i. e. , how much to pay dividend and how much to retain for future expansion. In order to make these decisions the management must have a clear understanding of the objective sought to be achieved. It is generally agreed that the financial objective of the firm should be maximization of owners economic welfare. There are two widely discussed approaches or criterion of maximizing owners welfare – (i) Profit maximization, and (ii) Wealth maximization. Profit maximization would probably be the most commonly cited business goal, but this is not a very precise objective. Do we mean profits this year? If so, then actions such as deferring maintenance, letting inventories run down, and other short-run, cost-cutting measures will tend to increase profits now, but these activities arent necessarily desirable. The goal of maximizing profits may refer to some sort of â€Å"long-run† or â€Å"average† profits, but its unclear exactly what this means. First, do we mean something like accounting net income or earnings per share? As we will see, these numbers may have little to do with what is good or bad for the firm. Second, what do we mean by the long run? As a famous economist once remarked, in the long run, were all dead! More to the point, this goal doesnt tell us the appropriate trade-off between current and future profits. Profit Maximization: Maximization of profits is very often considered as the main objective of a business enterprise. The shareholders, the owners of the business, invest their funds in the business with the hope of getting higher dividend on their investment. Moreover, the profitability of the business is an indicator of the sound health of the organization, because, it safeguards the economic interests of various social groups which are directly or indirectly connected with the company e. g. shareholders, creditors and employees. All these parties must get reasonable return for their contributions and it is possible only when company earns higher profits or sufficient profits to discharge the obligations to them. As long as we are dealing with for-profit businesses, only a slight modification is needed. The total value of the stock in a corporation is simply equal to the value of the owners equity. Therefore, a more general way of stating our goal . Finally, our goal does not imply that the financial manager should take illegal or unethical actions in the hope of increasing the value of the equity in the firm. What we mean is that the financial manager best serves the owners of the business by identifying goods and services that add value to the firm because they are desired and valued in the free marketplace If we assume that stockholders buy stock because they seek to gain financially, then the answer is obvious: Good decisions increase the value of the stock, and poor decisions decrease the value of the stock. The goal of maximizing the value of the stock avoids the problems associated with the different goals we listed earlier. There is no ambiguity in the criterion, and there is no short-run versus long-run issue. We explicitly mean that our goal is to maximize the current stock value. Because the goal of financial management is to maximize the value of the stock, we need to learn how to identify those investments and financing arrangements that favorably impact the value of the stock. This is precisely what we will be studying. In fact, we could have defined corporate finance as the study of the relationship between business decisions and the value of the stock in the business. Wealth Maximization: The term wealth means shareholder’s wealth or the wealth of persons who are involved in business concern. this is also known as value maximization or net worth maximization The wealth maximization (also known as value maximization or Net Present Worth Maximization) is also universally accepted criterion for financial decision making. The value of an asset should be viewed in terms of benefits it can produce over the cost of capital investment. †¢Wealth maximization is based on the concept of cash flow . cash flow are a reality and not based on subjective. †¢It considers time value of money.

Everyone needs a family to love :: essays research papers

It was no coincidence that I met a very wise person in my life. Now this person I found was always there for me! Wherever I went I knew they were in my heart to help me out, just to make things clear I’m not talking about God (even tough he is very wise and trustworthy) I’m talking about my family, the ones that have raised me since I was small and helped me through my life to get where I am today! They were the ones I knew I could count on to help me, but in the beginning I took them for granted and just there to live with and feed me, I never thought they would help me the was have! Well I was just sitting down with my dad and having a conversation about life, which soon ended up as an argument and the meanie that he is, I got grounded and had to do community project work for 4 whole months(BORING!!!). Now you see my dad is a very strict and did anything for his community and was always a few centuries behind, but he was the one that got me to find the real me! Well on the first day of my ‘community service’ I had to clean up the beach, which I found EXTREMLY boring! On the second day I did the same thing and did the same thing for 3 whole months. But on the fourth month I was told I was going to a work at an AIDS Children Orphanage, it sounded better than the beach so I went there. As soon as I walked in I could here all the children screaming with joy as another person came in to play to feed to teach them! These children looked as if they had no worry in the world, they didn’t know they were very sick they just knew they wanted to learn and play with people so much, some of the didn’t know what it was like to have a mother, a farther, but they seen to live just as well, but they needed that extra bit of love that your parents give. I found out that day how blessed I was to have a loving family always there to back me up, before I took them for granted I thought they were a waist of time I could live without them, which is true I could look at those children, but I realised that my family gives me that sense of security and of hope.

An Overview Of Phytoremediation Environmental Sciences Essay

Phytoremediation is a set of inactive engineerings utilizing green workss to take pollutants from the environment largely dirt and land H2O, devouring merely solar-energy. Unique biological mechanisms in workss like their ability to uptake and hive away toxic contaminations, change overing toxic contaminations to less risky substances and the symbiotic association of workss with bugs in their rhizosphere are studied and applied harmonizing to the status of the site to be remediated. Plants are used in such a manner that environmental toxins are removed, degraded or immobilized resulting in healthy country sites for better and more good usage. Proper pick of workss is made. If all of import factors sing the remediative action of workss are kept in head so the debasement or remotion of harmful chemicals from dirt and H2O can be accelerated utilizing any suited method of Phytoremediation. Phytoremediation has ever been an underrated engineering and much attending was n't given to it unt il really late when successful efforts of taking heavy metals ; like arsenous anhydride, nickel, crude oil hydrocarbons, pesticides and other toxic chemicals from dirt and land H2O were reported with the usage of workss. Phytoremediation is the usage of workss to take pollutants from the environment or to covert them to less harmful compounds ( Gleba et al, 1999 ) . Plants are used in such a manner that environmental toxins are removed, degraded or immobilized resulting in healthy country sites for better and more good usage. Combinations of different engineerings are applied for efficiency but the focal point ever remains on speed uping debasement of organic contaminations and on remotion of risky heavy metals in dirt or H2O. The metals targeted in Phytoremediation include lead, Cd, Cr, arsenic and radionuclides ( Raskin et al, 1997 ) . In Phytoremediation the demand to dispose off the transformed stuff to some topographic point else is excavated therefore doing the procedure easier. Phytoremediation can be done at the really site of taint known as in-situ like near the surface soils or in the deep aquifer. The option is that dirt or H2O samples from the country to be treated can be separated and Ph ytoremediation can be applied on them, this is known as ex-situ. Examples of the latter one include extracted ground H2O or surface H2O ( Agarwal, 2005 ) . Now scientists are taking acute involvement in Phytoremediation and to convey in limelight more about this works genetic sciences are besides being taken into history. There is no uncertainty that in approaching old ages Phytoremediation will go one of the most of import of all green engineerings.MECHANISMS OF PHYTOREMEDIATIONPlants carry out Phytoremediation due the many interesting and utile belongingss that they have like the capableness to pull out and concentrate assorted compounds from the environment. Others use the micro-organisms nowadays in Rhizosphere ; zone around the root, to transport out phytoremediative action. Microbial Activity in the root country: Microbes which can take phytoremediative action are present in the rhizosphere. These include both bacteriums and Fungis which make a symbiotic relationship with workss. This mechanism of Phytoremediation is termed as Phytostimulation. Plants secrete particular bio-enhancing compounds into the dirt which stimulate the bioactivity of bugs. These exudations are really a beginning of C and N because they largely include Amino acids, saccharides, polyoses, phenols and flavinoids. They support the growing of bugs that degrade toxic compounds. Root systems besides provide a high O content which enables bugs to boom easy. Fungi and other groups of bugs release extracellular enzymes which besides aid the procedure as Rhizosphere microbic debasement. Pure civilizations of Pseudomonas fluorscens and Chyrsobacterium indologenes found in rhizosphere can degrade mefenoxan, a antifungal to free acid in approx. 54 hours ( Pai et al, 2001 ) . The efficiency of rhizosphere debasement by bugs depends upon the species of workss involved because every works interacts with bugs in its ain manner ( Shaan and Boyle, 1994 ) . Root exudate straight effects the action of bugs on contaminations. If contaminations are ab/adsorbed or uptaken by works roots more, their bioavailability to microbic community lessenings. Wetting agents if added ; increase bioavailability of contaminations to microbes. Alfalfa works was studied in four different control groups: Planted diesel-contaminated and uncontaminated dirt, and Un-planted Diesel contaminated and uncontaminated dirt ( Kim et al, 2006 ) . After a stabilisation clip of 7 hebdomads the remotion efficiency was seen to be 82.5 % in deep-rooted diesel-contaminated pot while in bulk dirt of remainder of the controls it was approx. 59.4 % . Microbial activity additions in contaminated dirt as many dirt bacteriums and hydrocarbon debasers are able to boom. Microbial population is greatly affected by the conta minant itself as compared to the works roots, because the contamination is a nutrient beginning for the bugs. 2. Hyperaccumulation of heavy metals: Some workss take remove toxins expecially heavy metals and metalloids etc from dirt and H2O by uptaking and hive awaying them as in Phytoextraction. This works tissue can be harvested and treated subsequently on by ashing, smelting, drying or composting ( Raskin et al, 1997 ) . Metallic elements can even be recovered from the ash which reduces risky waste and besides gives us a metal resource that can be expeditiously used. Many hyperaccumulating workss frequently do non take up every bit much of the contamination as they can because it is extremely sorbed on the dirt so is non bioavailable to the works root. For illustration Brassica juncea has the familial capableness to roll up lead but it still does non get much lead into its biomass when grown in contaminated dirt. Application of chelating agents like EDTA a few yearss before crop can cut down this job of missing bioavailability. Iron-Chelating compounds like Phytosiderophores can be applied to dirty which can mobilise Cu, Zn and Mn every bit good ( Raskin et al, 1997 ) . Phytochelatins have been observed as efficient chelators of As in Holcus lanatus ( Raab et al, 2004 ) . Biostimulants can merely be added to dirty because they perform the action of both phytosiderophores and phytochelatins. These include humic substances, lactic acid oligomers ( Kinnersley, 1992 ) , reductases released from works roots ( Welch et al, 1992 ) and dirt souring proto ns ( Crowley et al, 1991 ) . Once the metal has been solubilized it is taken up by the roots. Plants have constitutional transporter systems for the ions that it has to take up like sultr 1 ; 2 sulfate transporter for Se or selenate ion. Nonspecific metal ion bearers and channels are present ( Clarkson and Luttge, 1989 ) and the of course needed ions and contaminant metal ions in dirt compete for these channels if they resemble structurally ( Cosio et al, 2003 ) . Apoplastic ( extracellular ) or symplastic ( intracellular tract ) is adopted for the conveyance of metals through the root and into the shoot via the xylem tissue. They travel with the xylem sap towards the foliages and are loaded in the foliages and shoot. Metallic elements may be stored in different types of cells of the foliage like the mesophyll or the cuticular cells. Arabidopsis halleri shops Zn in its mesophyll cells ( Kupper et Al, 2000 ) . The signifier in which the metal is stored besides depends on the works in some instances. Pteris vitatt a conveyances arsenite ion more expeditiously to the fronds than arsenate ion ( Wang et al, 2002 ) . In some instances, while the toxic metals are being transported to the foliages they may be converted to less toxic signifiers by complex formation or transmutation. This falls in the class of phytotransformation. Endogenous works compounds go through chelation with the toxins therefore changing their toxic belongingss. Segregation or storage of metal contaminations largely occurs in the vacuole off from any cellular metabolic tract that it may upset. The metal ions frequently remain in the cell-wall when the metal-ligand complex base on ballss though to come in the works cell because of the negative charges that the cell-wall holds ( Peer et al, 2005 ) . Segregation may happen in different compartments of the cell wall and in the vacuole varying from works to works. For illustration in Pteris vittata Arsenic is sequestered in extra-cellular and sub-cellular compartments while in Hol cus lanatus segregation occurs in vacuole. 3. Absorption of contaminations by works roots: This mechanism of consumption of contaminations in roots is dependent on the high surface country biofiltration system formed by the roots and is really efficient in ab/adsorbing pollutants particularly from H2O. This is frequently termed as Rhizofiltration and is chosen to take toxic contaminations from H2O systems like watercourses or agricultural tally away set up, industrial discharges and atomic wastes etc ( Salt et al, 1998 ) . First of all the workss are given a little sum of the contaminations in order to acclimatize or accommodate them. Once the workss are adapted to that stuff and can absorb it they are transferred to the existent site where they take up every bit much of the contamination as they can. Once the roots are saturated the workss are harvested. Plants with big root country are preferred because the whole procedure is dependent on soaking up and surface assimilation on the roots. There are opportunities that alimentary consumption will be blocked by the metal consumption because both occur through the same way. To extinguish this a ‘feeder bed ‘ is introduced ( Dushenkov et al, 1995 ) . This is an unreal dirt bed a few centimetres deep on which foods and fertilisers are applied. Plants get their nutrient from this bed, while the roots move down farther and make the site of taint excessively. Here they remove the contamination from land H2O and dirt so the two procedures do non halter each other. Many different biological procedures are involved in rhizofiltration like intracellular consumption by roots, deposition of metals in vacuoules, and translocation of metal to shoot. Deposition can happen both inside and outside of cells in the signifier of a dense aggregation, as in the instance of lead which can be seen through microscope ( Malone et al, 1974 ) . Inside the cell it occurs in vacuoles while outside in cell-walls. Lead exists as lead carbon ate in cell-wall ( Kumar et al, 1995 ) and besides binds through anionic binding ( Broyer et al, 1972 ) . It was seen by Salt and his co-workers that aqua-cultured ( grown in aerated H2O ) seedlings showed much better rhizofiltration than roots themselves ( Salt et al, 1997 ) . They called it Blastofiltration. The ground is the invariably increasing surface to volume ratio of the germinating seedlings as they are in a really immature phase of growing. 4. Removal by transition of contaminations into volatile signifier: The procedure in which workss take up contaminations in dissolved signifier with the H2O through their roots from the dirt, transport them to their foliages and so let go of them into the atmosphere via transpiration through their pore is called phytovolatilization. Compounds like Se and quicksilver are volatilized as such or can besides be converted into their biomethylated signifiers to be volatilized as in the Selenium which is foremost converted to dimethylselenide by bugs and algae and so phytovolatilized by works ( Neumann et al, 2003 ) . Brassica juncea has been identified to expeditiously take Se from dirt by volatilization ( Bauelos et al, 1990 and Bauelos et Al, 1993 ) . It was proposed that Se volatilization as methyl selenate is one of the chief mechanisms of its remotion ( Zayed and Terry, 1994 and Terry et Al, 1992 ) . A outstanding research was done in this field utilizing Arabidopsis thaliana which co ntained mercurous ion as HgCl2 ( Rugh et al, 1996 ) . Elemental quicksilver is in liquid signifier and is much more easy volatilized. A cistron coding for mercurous ion reductase was introduced into the works which reduced mercurous ion to elemental quicksilver therefore increasing quicksilver vapor production as compared to normal workss. 5. Immobilization of contaminations at the site: Here contaminations are stabilized by curtailing their motion in dirt. This is done through minimising free dust, by diminishing dirt eroding and cut downing the bioavailability and solubility of contaminations. The add-on of alkalising agents, phosphates, organic affair and bio-solids lessenings the solubility of polluting compounds in the dirt and therefore prevents it from making land H2O. Plants that have high transpiration rate like grasses etc are helpful for phytostabilization because they decrease the sum of land H2O which is taking off or assisting the contaminations mobilise in the dirt ( Suresh and Ravishankar, 2004 ) . Unlike phytoextraction, or hyperaccumulation of metals into shoot or tissues, phytostabilization chiefly focuses on segregation of the metals in the root zone but non in works tissues. Consequently, metals become less bioavailable and injury to livestock, wildlife, and worlds is reduced ( Mendez and Maier, 20 08 ) . It can be applied temporarily to immobilise the contaminations at the topographic point and halt them from distributing in the country. One must at all times be careful of the fact that a reversal of metal immobilisation can happen, with associated unfavourable environmental effects ( Alkorta et al, 2010 ) . Experiments have shown that phytostabilization has been successful in take downing the degree of lead in a sand mixture. Metal leaching or flight is reduced by change overing metals from a soluble oxidization province to an indissoluble oxidization province for illustration the transition of available toxic Chromium IV to unavailable and less-toxic Chromium ( Agarwal, 2005 ) . 6. Conversion of contaminations to less toxic compounds: Contaminants present around the works are degraded into less toxic compounds by the works itself through it enzymatic metamorphosis or the bugs in the rhizosphere carry out this transmutation. The latter instance has already been discussed as rhizosphere microbic debasement. Once the works has taken up the contamination it will hive away it in the vacuole so that its metamorphosis can be done subsequently or it will be converted to Carbon dioxide and H2O and so transpired. A common job is that of pesticides that is sprayed on workss and can go toxic for human ingestion excessively. Atrazine a pesticide is transformed to anneline ( Agarwal, 2005 ) . TCE and other chlorinated dissolvers are transformed to carbon dioxide, H2O and chloride ion ( Peer et al, 2005 ) . Poplars have widely been studied for their phytotransformational belongingss. Ammunition waste like TNT, RDX and HMX are partly transformed by them ( Thompson et al, 20 09 ) . Once the toxic compounds are broken down into smaller constructions, it can be incorporated to organize new works stuff or released as organic dirt constituents. Plants produce enzymes that have active sites that can adhere and move on common organic compounds frequently taken up by workss from dirt or other beginnings. For illustration the organic compound Nitrotoluene is wholly degraded by nitro-reductase and laccase enzyme. Besides aromatic ( cyclic ) compounds even if they are non organic can be acted upon by enzymes like oxido-reductase nowadays in the foliages, roots and roots of workss.DecisionWhile the human race is confronting jobs in economic sector, its jobs are being multiplied by the depletion of natural resources. One of the major reverses being experienced now is environmental debasement which can be fought really efficaciously by the use of workss. This helps in keeping non merely our natural resources of a clean ambiance and dirt but besides lead to a healthy nutrient web. Phytoremediation has successfully given us parts of Earth with lowered degrees of toxic metal contaminations in its dirt. On the other manus the same belongings of workss to roll up metals in them has been utilized to extinguish hint metal lacks in animate beings. Unique set of biological mechanisms of workss are studied and so applied as Phytoremediation. Plants give an consequence which is non merely aesthetically pleasant but helps halt the devastation of environment excessively. Feasibility of the technique being used can be checked by first analyzing the site to be remediated and so make up one's minding what technique ought to be used. This field of biotechnology has opened new doors towards a really bright and promising future-use of workss other than in agribusiness. All of this process is really cheap and this extremely preferred but the drawback is big span of clip required for efficient consumption of heavy metal or any other toxic compound being removed fr om the dirt country or H2O being remediated. Although Phytoremediation, being a non-agricultural usage of workss, may non assist in feeding the hapless portion of the universe but still its application will give a healthy environment assuring a better quality of life.AbbreviationBTEX: Collection of compounds ( Organic pollutants ) ; Benzene, methylbenzene, Ethylbenzene, Xylene EDTA ( chelator ) Ethylene Diamina Tetra-acetic Acid CDTA ( chelator ) Trans-1,2-Cyclohexane diamine Tetra-acetic Acid EDDHA ( chelator ) Ethylene Diamine-N, N'-bis ( 2-Hydroxyphenyl Acetic acid ) Trichloroethylene: Trichloroethylene Trinitrotoluene: 2,4,6- Trinitrotoluene RDX: Research Department Explosive besides called hexogen ; hexahydro-1,3,5-trinitro-1,3,5-triazine HMX: Nitroamine explosive called Octogen ; octahydro-1,3,5,7-tetranitro-1,3,5,7-tetraazocine

“Review of AIDS and Stigma’ by Gregory M. Harek

The current literature as of 1999 is reviewed regarding the stigma that attaches to people with AIDS (PWA’s and people with HIV (PWHIVs).   Ã¢â‚¬Å"Stigma† refers to discrimination and prejudice directed at PWAs and PWHIVs as well as those people associated with them or caregivers for them.This stigma has resulted in firings, evictions, and other forms of prejudice to people with AIDS and HIV. The existence of stigma has had a bad effect on the response to the AIDS crisis and could have a continuing affect on the various policies designed to assist PWAs and PWHIVs.Surveys throughout the world and specifically in the United States have indicated a negative attitude towards PWAs and PWHIVs by a significant majority of people.There are several possible reasons for the stigma. Many people believe PWAs and PWHIVs got the disease by their own actions and behavior. Others fear contracting the disease from any contact with PWAs and PWHIVs.Then there is the stigma associated wit h any disease considered that cannot be cured followed by the fear of contracting a contagious disease. Finally is the stigma associated with diseases or conditions affecting the victims’ outward appearance and capability.The stigma of AIDS has an impact on a personal level and with society and public policy.   For example, many people with AIDS or HIV do not get tested for fear of the stigma attached to the disease.In society the negative attitude has and continues to have an effect on public policy and public health issues and legislation. However, the situation has changed over the years with education, and with continued education discrimination and prejudice towards PWAs and PWHIVs will further decrease.I like this article for several reasons. It is well written and organized. It is written in a style and manner which is easy to read for the average student.There is no specialized language or information presented. Additionally there are no graphs or tables of statisti cs or lengthy quotations or references to other work. There is no detectible bias in the article. It is a very relevant topic today as much as it was when written. It is very thought provoking and informative regarding a variety of issues.The issue of stigma can have a very strong affect on the individual reader, as it has had on me. Unfortunately AIDS has spread to the point where more and more people know of someone afflicted with the disease or know someone who has been directly affected by the disease.With this increase comes the awareness of the stigma associated with PWAs and PWHIV, and the likelihood that someone we know has suffered from discrimination or prejudice.There is an â€Å"association† effect as well, when there is a similar prejudice, discrimination or fear of people who take care of or are related to PWAs and PWHIVs. The information presented in the article cannot help but make the individual aware of the issue if he or she is not already familiar with the disease, and adds knowledge to those who are familiar with it.Additionally, it makes the individual, and me, question whether or not I harbor any prejudice or discrimination and if so how I exhibit it. This article is very good at making me look past myself to broader issues, as well as to look inside myself for attitudes I should question.I particularly like the method in which the causes of stigma are presented. It is particularly helpful in examining whether or not I believe in any of the reasons or use them as an excuse. It is also helpful in realizing the fallacy of many of the reasons.The first reason presented seems very irrelevant, as regardless of how someone contracted AIDS or any disease should have no bearing on attitude, although for many people religious belief may be a factor that cannot be easily ignored.The second reason, fear of contracting the disease, was a personal fear of mine until I became aware of the fact that it cannot be contracted by casual contact. Com mon sense tells us that we are probably around PWAs and PWHIVs daily without knowing it, and there has been no cases caused by casual contact.The third and fourth reasons are the ones that I have the most difficult time with, as I have always been uncomfortable around people with life-threatening or terminal diseases, or people who obviously show outward signs of the disease.I believe many people have this discomfort, and probably always will, as it can be very difficult to interact with such strong issues â€Å"in the background†. However, what is important is to keep the discomfort into becoming a prejudice or source of discrimination.I really liked the article because it is hopeful. It has taken a very difficult and depressing topic but presented it a manner which gives optimism to the issue. It does this by making the reader aware of the reasons, and on reflection, realizes all of the reasons can be lessened or removed with awareness and education.It has made me more awar e of a very significant issue in society today. It has also caused me to reflect on my personal attitude and actions. It has clearly presents a thesis and evidence in an easy-to-read manner.I like it because it stresses how common and damaging prejudice and discrimination is, and the role of education in overcoming prejudice, which is important not just for PWAs and PWHIVs but for everyone. Finally, it is an article I can use as reference to anyone who can benefit from the information or may be interested in the issue.Works CitedHarek, Gregory M. â€Å"AIDS and Stigma†.

Men and women are stereotyped everyday on how they should act and behave. What should be the difference in the book One Flew Over the Cuckoo’s Nest? Well one could say that the roles have been reversed to a certain point. The mental hospital is a little world inside that is a made to scale prototype of the big world outside (McMahan). Patients are entered under the nurse’s power and will be released when they can contribute to society again. In the book as one can guess, some stereotypes are backwards. Nurse Ratched is one woman in the story that doesn’t play to the role of a nurse. The big nurse’s name, Ratched, suggests â€Å"ratchet† (a mechanism consisting of a notched wheel, the teeth of which engage with a pawl, permitting motion of the wheel in one direction only)(Macmillan). Her name makes her out to be an unchangeable character. Nurse Ratched is more made out to be a machine then a real person, unlike the other nurses, who seem to be kind, caring, and compassionate. Totally opposite of Nurse Ratched is the prostitutes. These women are fun free spirits that enjoy spending time with the patients and doesn’t try to humiliate or ware down the men to feel nothing. These are the two main types of women in the story and how they act towards the patients. Kesey takes the worst male stereotype availablethat of over-weening power, control, force, manipulation and imposes it on the nurse in the book, and the worst female stereotype pettiness, bitchiness, lack of self-confidence, anxiousness to serveand imposes it on most of the male patients (McMahan). Women are stereotyped in the novel just not as one would think. The novel may give women a more masculine view, but I would not go, as far as to say it is a sexiest view. If the novel was charged with being sexiest it would have to be against the men for making them look like sissies. The woman stereotype is getting old anyway.

On the other hand, self-esteem refers to the respect that a person has for himself or herself. Self-esteem is an extremely vital concept since it affects functional behavior, motivation, as well as life satisfaction (Bordens & Horowitz, 2002). Individuals who have high self-concept about themselves normally have positive thoughts. In this regard, they have high self-esteem of themselves. Having high self-esteem is a critical component in one’s life since it gives one confidence about his or her self-worth. In this regard, an individual can compare himself to be attractive. Being attractive entails several components, and personal hygiene is one of the components (Harter & Bukowski, 2012). Therefore, one must assess his or her personal hygiene in the wake of evaluating
