Policy Change Essay Example for Free

Policy Change Essaywellness interest insurance started gaining popularity in the 1940s, when people and wellness institutions began to realize that insurance spreads the risk of high-ticket(prenominal) medical conditions across a large population base. Thus, it prevents personal bankruptcy in case of serious health conundrums. Health care insurance as well makes health care services more accessible to the public. However, as you know, a bigger part of the population remains uninsured, because they are incapable of paying the address of health care coverage on their own (Brayton Purcell LLP, 2007). The United States government continuously battles, policy-wise, the problem of high rates of uninsured people. Many efforts to solve this problem through public assistance or welfare approach are yet to find success (Long, Coughlin King, 2005).While I appreciate the fact that your squad has successfully lowered the steep uninsurance rates, various states of the Union continue to register high uninsurance rates (U.S. Census Bureau, 2007). Moreover, many of the members our population still depends on due/personal coverage, coverage procured by employers, and public coverage such(prenominal) as the one you provide for their health care inescapably (U.S. Census Bureau, 2007 Hadley Holahan, 2004). Noting your history since 1965, it is praiseworthily that you have since been able to meet the needs of countless poor persons and fulfilled the mandate of the U.S. government, by providing coverage to those who are eligible for federal officially supported, state-run welfare programs (Long, Coughlin King, 2005). I note that that you followed strict federal guidelines that must be observed in order to enable the program to assist families who could not afford the cost of health care insurance (Long, Coughlin King, 2005). Nevertheless, I am of the opinion that there is still a big gap to be filled, in terms of providing health care coverage to our poor brothers a nd sisters in our nation. While it is wonderful that Medicaid coverage has increased since 1965, and now includes persons with disabilities, Medicaid is still unable to meet the needs of a large bulk of the population who could not afford to pay for health care services (U.S. Census Bureau, 2007). Hence, I am appealing to you that you consider expanding your sources of funds, aside from local and federal funding coming from our country, to include those provided by private industries who could afford to give humanitarian support. Moreover, it would be helpful to your cause if you could seek help from international organizations such as the World Health Organization and World Bank for much needed funding. This way, your organization would be better equipped to meet the challenging needs of our poor population. I hope you would consider my suggestion, and I wish you more power in your noble endeavor.ReferencesBrayton Purcell LLP. (2007). Medical Issues Include Uninsured Workers and I nadequate Health Care.

Impact Of Smuggling In The Philippines Economics Essay

Impact Of Smuggling In The Philippines Economics EssayRaymond Palatino (2008), writings The extent and impact of smuggling in the Philippines that Smuggling is a serious problem that hurts the rude in many ways. It deprives government of revenues from uncollected taxes and tradition duties. It affects local industries by distorting prices of commodities. Smuggling causes production s commencementdown, which leads to mass lay-offs, reduced consumer spending, bankruptcies, and lower tax collection. Smuggling has especially benefited from weak governance and chronic political instability.The author further added that when the government reduced the tariff rates on merchandise articles, many economists and merchants expected a decline in smuggling activities. They believed the tariff reduction would cook discouraged illegal importation of goods since on that point will be fewer taxes to pay on the part of importers. But even with reduced tariff rates, smuggling persists up to this day. From used clothing to shoes, second-hand and luxury cars, agricultural products, garments, ceramic tiles and jewelries, cheap smuggled pitch-black are flooding the local market, which wipes out the earnings of small honest traders.The author compared the import-export data Data show the disparity of import-export figures between the Philippines and its trading partners. In 2000, trading partners describe that they exported $45-billion worth of goods to the Philippines, but government figures registered only $34-billion worth of imports. This means that more than $10-billion worth of goods were unaccounted, nethervalued or misdeclared.In 2002, China exported 3.9 million second power meters of ceramic tiles to the Philippines, but only 600,000 substantial meters were recorded in the Bureau of Customs. The following year, 4 million square meters of ceramic tiles were exported to the Philippines, but only ccc,000 square meters were recorded in the BOC.From January 2001 to June 2003, authorities confiscated a check of 1,517,387 bags of smuggled rice worth P1.18 billion. Since 2006, a total of 100,000 smuggled vehicles were shipped into Subic Bay Freeport. Last year (2007), 4 billion liters of oil were lost to smuggling.The author concluded that Smuggling clearly destroys the local economy and exacerbates poverty in the country as manifested by the ending of local industries, decline in agricultural production, uncompetitive agricultural products, loss of jobs, unfair competition, loss of government revenues, heightened corruption in the bureaucracy, and risks in consumer welfare.Milton Ayoki (2003), explained in his wallpaper The hidden costs of doing business in Uganda that the problem of smuggling has been particularly serious for goods like petroleum fuels, cigarettes, sugar and other highly taxed or latent revenue sectors such as steel, leather, wood, textiles, bicycles and chemicals as major deterrents.The author further added that apart from the huge revenue losses involved, smuggling is killing local businesses and causation great inequality and other effect is that illegally imported goods are steadily displacing some locally produced goods in the market place. This is adversely affecting twain employment and profit margins in domestic industries.Luk Joossens (2003), written in his article Vietnam smuggling adds value thatInternal British American Tobacco (BAT) documents lease been unequivocal about the knowledge of cigarette smuggling into Vietnam. 555 cigarettes is the major smuggled brand and there is no doubt it has a tremendous image and sales potential difference in the country.The author added that BAT documents describe in a detailed way the smuggling route for 555 cigarettes were produced in the UK, shipped to Singapore, sold to importers and traders in Cambodia, and then transported illegally across the border to Vietnam.Joossens argued that the industry has always claimed that smuggling is the result of t axes being too high.UNDP (1995) viewed the taxes on opium exports to the mainstay of Taliban income and their war economy. It revealed that Afghaniistan-Pakistan drugs exports were earning some 50 billion rupees (US $ 1.35 billion) a year. Alongside the drug trade, the traditional Afghans smuggling trade through Pakistan and now the Gulf States, expanded under the Taliban, creating economic havoc for the neighboring states. This trade was estimated be the largest trade source of official revenue for the Taliban and generated an estimated US $ 3 billion annually for the afghan economy UNDP disclosed that through the customs officials in Kandahar, capital of Afghanistan and Herat refused to disclose their daily earnings, but with some 300 trucks a day passing through Jalalabad and Kabul to the north, daily earning were considerable. The illegal trade in consumer goods, fare and fuel through Afghanistan crippled industries, reduced state revenues and created periodic food storages in all neighboring countries.The World Bank (1997) report on Afghanistan Pakistan dispense Relations as a part of its ceremonial occasion brief strategy for Afghanistan, accounts for the total trade between Afghanistan and Pakistan at $2.5 billion in which the unofficial re-export from Afghanistan to Pakistan has the loins share. The study assessed that the long and porous border between the two countries, the need for basic goods in Afghanistans warn-torn economy, weak border controls, high import tariffs in Pakistan on goods prone to smuggling and the low cost risks were important reasons behind the large and growing unofficial trade between the two countries. This report further added that there was an evidence of expansion of official and unofficial trade in locally produced goods between the two countries, which was likely to increase substantially if there was peace and post-war reconstructive memory in Afghanistan. In Pakistan, the imports competing industries have been harm ed. The study also estimated that the government of Pakistan had been loosing substantial revenues due to tax evasion and fungibility of routes through which un-official imports enter the country.Rashid (1999) in his prevail Taliban, recorded that the smuggling trade to and from Afghanistan became the most devastating manifestation of the losses being sustained by the government of Pakistan during the Taliban regime. According to him, this trade, which now extends to central Asia, Iran and Iranian Gulf, represented a crippling loss of revenues for all these countries, but particularly Pakistan, where local industry has been decimated by the smuggling of foreign goods. Rashid elaborates further, What is euphemistically called the afghan pass trade (ATT) has become the biggest smuggling racket in the world and has enmeshed the Taliban with Pakistani smugglers, transporters, drug barons, bureaucrats, politicians, police and army officers. This trade became the main source of official income for the Taliban even as it undermined the economies of neighboring states.Rashid also points out that the border post between Chaman, in Balochistan province, and Spin Boldak, in Afghanistan, is a prime location for watching the rackets at work. His estimates accounts for 300 trucks crossing from Afghanistan to Pakistan on a good day. The goods which these trucks carry, have no invoice and cross up to six international frontiers without having route permits, madcap license or passports. The consignments on these trucks range from Japanese camcorders to English under-wear and Earl gray tea, China silk to American computer parts, Afghan heroin to Pakistani wheat and sugar, eastmost European Kalashnikovs to Iranian petroleum and nobody pays custom duties or sales tax.Inter press service, a news agency (2001), found Indian drugs to have found ways to Pakistani markets, adding yet another dimension to the cross border illegal trade to and from Afghanistan. The agency named aspi rin, Amoxiline, Ampiciline, Corimaxazole, Laxotanill, Cyprafloxine, Renitidine, Fametidine and Cemedtidine to be selling in salient medicines shops of the province. The agency further disclosed that unlike the settled areas, where the sale of Indian drugs was banned and those found guilty of conduct were liable to severe penalties, the tribal areas were kinda immune to such repercussions. Like all other duty free smuggled goods, Indian drugs were evaluated by the agency to be 10 times cheaper than the drugs of the resembling brand and effect, produced by multinational companies (MNCs) in Pakistan.Citing reasons for this price disparity, the agency added that unlike India, where the MNCs were bound to use raw materials from India, the government of Pakistan allowed them to import raw materials from their parent countries which entailed laborious tariff duties. Similarly, quoting the findings of international regional office for Asia and pacific, the agency counted 26 commonly con sumed drugs to have very high prices in Pakistan as compared to India.The agency while discussing the imparting of drugs, revealed that along with other goods, Indian drugs were smuggled into Afghanistan, to Pakistans tribal areas and then finally to Peshawar. The report also disclosed that Afghanistan received thousands of US dollars worth of medicines, each month, from Indian, under a bilateral agreement, but some unscrupulous agencies in Kabul were apparently making huge profits from selling them in tribal areas.The report further discovered that due to the mutual collusion of the MNCs, health department functionaries, and other government officials, the measure of the government to import drugs from china, Bangladesh, Bulgaria, Poland and Yugoslavia to counter the smuggled and low priced Indian drugs, has miserably failed.Awan (2001) put the Pakistan bound trip goods to Afghanistan at Rs 14.97 billion during 1998-99. Prominent among these goods were safety razors, worth Rs 120 million, cosmetics Rs 150 million, minerals water, Rs 200 million, electronics worth Rs 300 million and telephone sets worth 160 million. The report pointed out that this trade, which has been conducted for the last 50 years, fetched billions of rupees to the tribal traders, related to the afghan counterparts and as much to the Pakistani customs and other law enforcing agencies, who facilitated this black trade.Awan also disclosed that previously, for decades, these Afghanistan bound transit goods were leaked into Pakistani markets before reaching Afghanistan. Owing to strict regulations imposed on the transit trade, it was very recently that the Afghanistan bound goods, at least, started crossing the border and then re-exported illegally to Pakistan. Awan pointed out that due to the high financial stakes of unlike stakes groups, law, customs and state machinery have lost their efficacy.Keeping the adverse fall out of the abuse of afghan transit trade agreement on the industrial sector of Pakistan, Awan suggested that other neighboring countries with sea-coast should also shoulder the responsibility of transit facilities to Afghanistan.The News, in its march 2, 2002 issue, reported that there has been an unprecedented increase in the smuggling of tea, spices and other utilities, through the afghan transit trade, during the last two years. This rise has been attributed to the massive under-valuation of these items at the countrys dry ports, especially Lahore, Gujranwala, Faisalabad, Quetta and in other cities, which were essentially established for providing facilities to the local traders at their door steps.The report added that these smuggled items are now openly sold at the Jodia bazaar, the traders from various parts of the country have opened their offices, which deal exclusively in smuggled items, mostly tea and spices through Quetta dry port into the city the dry ports established in various parts of the country have become a major source of smuggli ng, mis-declaration, under-invoicing, tax evasion and theft, detrimental to the government treasury, it alleged.The repot revealed that since 1988, the smugglers switched to smuggling of eatable products as they found this proposition to be highly lucrative. The smuggling of items originates from Dubai, via port Bandar Abbas in Iran, to Afghanistan and ends up into Pakistan. Probing the matter, the report discovered five percent increase in the custom duty during the 2001 budget, plus the total tax increase of 70 percent, to be the main reasons for the rise in smuggling.Daily Aaj, on 16 July, 2009 reported that during the year 2008-09, eight hundred million kg of tea is smuggled into the country, only 4.9 million kg smuggled tea is less then from the total imported tea. This year government losses Rs 5 billion in shape of tax evasion due to smuggling of tea.Through reliable sources, Afghan Transit Trade (ATT) is the main source of tea smuggling in the country. The total import of te a was 10 million kg during the period of July 2007 to June 2008. This was imported in one year from Kenya about 53.9 % while in previous year that was 61% from the same country. Which was 7% dropped in tea imports.

The First Epistle of the Second Book of Horace Imitated

The First Epistle of the Second Book of Horace ImitatedLiving and writing in an era in which culture was flourishing and metrical composition was non simply a pastime1, must realize been a dream to Alexander pontiff such was the Augustan hop on in Latin literature (27 BC AD 14), which under the reign of the emperor Augustus provided not lonesome(prenominal) for a serene social environment for the booming of liberal arts, but also concerned about its good management by the close advisor Maecenas, responsible of the patronage of the artistic talent. In this sort out of literary scene, poets such as Horace, Ovid, Virgil and Livy found their mastery being appreciated, highlighted and celebrated.Approaching the two historical periods with a thorough close analysis, its remarkable how pontiffs England and the Roman conglomerate were sharing aspects of their social life the division between Court and Country as existed in the Augustan capital of Italy was common view in England as the difference between luxury and philosophical retreat. A literary analogy, specifically relevant for Popes works, could also be detected, but in terms of cultural and social satisfaction, unfortunately, the 18th Century poet faced a reality which of Augustan had nothing but the name.The so called Augustan poetry rose during the first half of 1700 with the transparent intention of being satirical and semipolitical, meant to criticise and hit the government, whose enmity and hatred towards all poetry and the arts were concentrated in the figure of the contemporary belief George II. Ascended to power in 1683, the monarch showed a non-caring and contrasting attitude towards every literary manifestation, often stating himself in favour of censorship that made poets voices and endavours even untold harder to be heard and adequately esteemed. Moreover, the spreading corruption was detestated by the writers of the time, and by Pope in particular, who in 1737 came into closer associ ation with the Opposition, expressing his role as an mobile political poet.Funnily, George II was also christened Augustus, coincidence that considerably remarked the difference between the two princes Alexander Pope didnt think twice about taking gain of this perfect homonymy and under the clever suggestion of his friend Lord Bolingbroke, he created a brilliant and enjoyable satirical collection Imitations of Horace (1738).Firstly, what an imposture is must be clarified not a fake, something not genuine should be thought about, but the Latin sense of imitatio should be taken into musing, in which the idea of recreation and re-interpretation is implied. Secondly, the choice of Horace must be explained not only he was on the defensive of writing satire, as Pope was towards his literary environment, but also gave him the relegate to rise questions and social problems besides giving judgments of contemporary literature and taste. These issues found their place in the mock-epic po em The first Epistle of the Second Book of Horace Imitated (May 1737), which also better underlines Popes contempt for George II, making of it a parodic effective thread over the poem.The Horatian Epistle opens with compliments since intrust paid by Horace to Augustus, while the mavins claimed in Popes version are to be constructed ironically the English Patron of Mankind in line 1 had nothing to do with the Horatian Caesar in line 4. The word caesar was not meant just to cross Augustus with his second name it is an important honorific that stands for the recognised authority and greatness of a leader, who could bear alone all the government and social duties, worth avocation with invest. The contrast between the two Augustuses is here even to a greater extent highlighted and as the English courtier Lord John Hervey defines it, it is a very material difference For as personal courage was the only quality necessary to form a great prince which the one was suspected to want, so I fear it was the only one the other was ever thought to possess. (p. 261, Memoirs).The game of the parallel ironic and glorific tone plays constantly throughout the poem such a Wonder of Kings Like whom, to pernicious eyeball None eer has risen, and none eer shall rise (line 29-30) becomes some monster of a King in line 210 and is still contraposed to the indisputable maiestas (line 258) of the Roman Augustus, or his greatness. This political complaint then is strictly connected with and leads the way to the real Epistles social concern.To start with, more than everything, Augustans of both ages were worried about their literary heritage and how they should have dealt with it. People and poets were happy and accostumed to praise primitives such as Shakespeare and Ennius, but a common sense of lacking of art of them was hanging in the air and hostile literature started being attractive after having conquered France in one case and Greece in the other. Horace could still see the sapiens et fortisEnnius (line 50) and his ingenium, the mastery he had demonstrated, as Pope would agree about Shakespeares immortality but another good way of doing literature was emerging and couldnt wait to be noticed.If Time improve our Wit as salubrious as Wine, Say at what age a Poet grows divine? (Pope, lines 49-50). Poets were scared of how much time might have taken for their works to be determine if people had remained stuck to the past for longer. For that, it was important not to leave the national be the judge in order to make sure the distance between the natural and the old, veteros and novos (Horace, lines 37-38), was respected and here the social context starts to shape.When the poets write about the public and their feelings towards it, there is where the two societies begin to clush and be really interactive. On more scientific basis, this connection is interestingly defined as time-space distanciation in The Dictionary of Human Geography, 4th Edition, for wh ich Anthony Giddens, British sociologist, describes the reach of social systems across time and space. Historically, The nexus of dealing political, economic, military in which a confederation exists with others is usually integral to the very nature of that troupe2 thus to maintain this interaction, which is intrinsic to society itself, so called technically symbolical tokens are implied, as media of exchange which have standard value and thus are interchangeable across a plurality of contexts (Modernity and Self-Identity, 1991).Put in context, these stretching and media of exchange seem fundamental in order to read in parallel Horaces and Popes societies. With the concept of time-space distanciation in mind, its easier to jump flexibly from one time to the other, from Rome to England and follow the thread that society weaves across the lines of the Epistle.Back to the relationship with the public, both poets are trying to warn about the misunderstanding of contemporary liter ature Pope assumes an explicit rude and insulting tone while declaring that the public is nothing but a fool (lines 93-94), while on his side, Horace takes a softer and much more diplomatic position by claiming that not always the public sees and interprets things in the right way and its now mistaken in believing that no poetry can match the old school but that in this case Iove iudicat aequo (God judges righteously, line 68). However, the Latin text suggests a different shade of what Horaces consideration of the public was he addresses the audience as volgus (line 63), which does not only refer to people in general but has to be read with a nix and offensive connotation that is effective on a class-based society, in which the mass was considered inferior and with scorn.The argue about the public goes on in lines 115-118 in Popes imitation I lose my patience, and I own it too, When works are censurd, not as bad, but new While if our Elders break all Reasons laws, These fools de mand not Pardon, but Applause. Fools that have no taste, a crowd that has no interest in welcoming the novitas, the novelty in literature (line 90, Horace) and still pays honorem et premia (honours and praises, line 78) only to the ancients Pope was clearly complaining about the audience but at the same time denouncing the ruling power and censorship that was affecting the literary environment. horizontal the writers profession seemed to be undermined, as for Indocti doctique (educated people and not, line 117) for Horace and those who cannot write, and those who can for Pope, All ryme, and scrawl, and scribble, to a man (lines 187-188). Unskilled writers were emerging and the public was enjoying them with incertos oculos et gaudia vana (line 188, Horace). The choice of the adjective incertos (uncertain) for the eyes (oculos) is interesting, as it doesnt only refer to the dubious taste of the public but also to a sort of inner ignorance that caused confusion and inability to judge, as if the public itself was botched. That might simply remark the mistrust and disdain for the audience in Horace but in Pope it assumes again a political connotation, in which the unskilled writer is just taken as a pretext and metaphor to criticise the unprofessional and unskilled George II.The poem is so constantly balanced on the coexistence of political and social context. They create the wire on which the reader keeps his equilibrium within the two Augustan societies, each of them narrated and sung by their poets with similar unless so different connotations in fact, their opinions about the literary taste converge in all their aspects but their perceptions of the possibility of dealing with power for it, differ. In this distinction lies the key point and crucial concept to change and light up the whole interpretation of the text and of the poets themselves.As previously mentioned, Horace was writing for and of Augustus, whom he could trust and relate to besides his audienc e whether the latter failed, the prince was still a solid pillar waiting for his courtiers words. On the other hand, Pope had no one to rely on the publics senseless and George II taken of any consideration. In this light, the Epistle takes the shape and significance of a social poem in which Horace is the image of that kind of society Pope wishes to live in and write for Horace becomes the means by which Pope wants to raise his voice and at the same time he makes him part of the society itself.More than a simple report of power misbehaviour hides behind the lines of the Epistle Pope puts in it his frustration and will, his anger and wish that a society of Horatian guinea pig could still be possible and viable and while this anger falls into satiric tones, he constructs on it an entire poem. The ideal of Horace and his actual figure jock Pope in bringing his age and society to life and as he states in the Advertisement to The First Satire of the Second Book of Horace Imitated, an upshot from Horace was both more full, and of more Dignity, than any I coud have made in my own person.In the last part of the Epistle, the presence of the poets becomes expressively strong. stand up in front of Poetry, Horace keeps his humble tone by declaring once again his scribendi studio (passion for writing, line 108) only aimed at celebrating Augustus maiestas he would blush, in fact, at a great tribute to him alone, departed from his patron. On his side, Pope sticks to that aggressivity that just conceals insecurity and finally reveals the real parodic biting3 intention of the Encomium. In the final lines he delineates a self-portrait, adjusting and immerging himself among the Georgian England, society for whom he felt the need to call for Pen and Ink4.BIBLIOGRAPHYPope, Alexander, Imitations of Horace, ed. by John Butt, Methuens English Classics, 1966Horace, Liber Secundus, Epistula I in Horatii Epistularum in Q.

Conditions for Malo-lactic Fermentation With Flavour Profile

Conditions for Malo-lactic fermenting With Flavour ProfileDescribe the conditions necessary for the successful consequence of a malo-lactic turmoil with a desirable tone of voice profile.MUGAMBHIKA.M.NABSTRACTMalolactic zymosis (MLF) is a biological process that is initiated in the boozemaking process to produce premium attri furthere of wines. The conversion of L-Malic battery- sulphurous to L-Lactic vinegarish by lactic acid bacteria (LAB) lead have a direct effect on the wine produced in terms of quality. MLF enlarges microbial stabilization, sensory attributes of the wine by trim back the acidity level in the wine(Versari et al., 1999). Desirable attributes such as honey, vanilla and smoother taste in wine has been reported by several studies which is cogitate to the enzymatic activity of Lactic acid bacteria during Malolactic unrest (Lpez et al., 2011).During drenching fermentation, the wine becomes hostile for Lactic Acid Bacteria, due to the presence of mel scu rvy grain alcohol study, SO2 and other chemical residues released by yeasts. But at a controlled level, they could be make optimum for Malolactic fermentation. The species of Lactic acid bacteria assisting spontaneous fermentation buy the farm to the Oenococcus, Leuconostoc, Lactobacillus genera. Although, Oenococcus oeni ar the predominantly used LAB. They argon considered to be ideal for Malolactic fermentation due to its specific oenological properties like reduced production of acetic acid, presence of enzymes that enhances the ol performery sensation and timber characteristics, decreased risk of wine spoilage(CHRIS POWELL, 2005, Chalfan et al., 1977).INTRODUCTIONWine fermentation is an important process carried out by microorganisms like yeasts and lactic acid bacteria. Malolactic Fermentation (MLF) is the enzymatic conversion of L-malic acid to L-lactic acid and Carbon dioxide by lactic acid bacteria. The importance of MLF in commercial winemaking process is due to the bi ological deacidification reaction by the wine lactic acid bacteria (LAB) (CHRIS POWELL, 2005). Malolactic Fermentation occurs after alcoholic transformation predominantly by Oenococcus oeni species. The bacterial activity during fermentation and its quality dep dismisss on the wine. Chemical and physical composition of the wine control the survival and growth lactic acid bacteria in wines(Toit, 2011).Malolactic Fermentation has vary effects on wine flavour and aroma. MLF do-nothing either occur spontaneously in wine or by addition of starter cultures that are commercially easy. With spontaneous MLF, there are different end results which is due to the native microorganisms that may occur immediately or few months after the completion of alcoholic fermentation. The indigenous microorganisms like lactic acid bacteria may start off from the vines and grape skin in the winery equipment. This leads to risks like increase in volatile acidity, delayed malolactic fermentation and growth of unfavourable metabolites like biogenic amines. Biogenic amines affects the quality of wines and affect human health. These are primarily make due to the decarboxylation of amino group acids by Lactic acid bacteria(Solieri et al., 2010). This could be tackled by using a defined starter culture. In order to improve the quality of wine through MLF, wine makers prefer to inoculate grape musts or wine with lactic acid bacteria starter cultures. These are commercially available in freeze dried form or fresh liquid forms. Although few winemakers prefer to use their own starter cultures by growing strains of lactic acid bacteria in diluted grape juice or wine(Bisson, 2004).Inoculated MLFInoculated starter culture in Malolactic Fermentation provides better control on the time of fermentation process and the organisms present. Bacterial starter culture is more difficult to maintain than the yeast starter culture, because the medium needs to be completely sterile and there is a high proba bility of unsuitable lactic acid bacteria occurrence. Fermentation occurs faster under high inocula. The percent inoculum that is inevitable to be used should be 1-50% depending on the vigour of culture(Semon et al., 2001).Spontaneous MLFThere are a number of risks associated with spontaneous malolactic fermentation. The timing of the process is sometimes unrestrained and there is a high threat of undesirable strains that could cause an off flavour in the wine. The timing of process is more certain for alcoholic fermentation than the MLF. This is due to the fastidious nature of bacteria occurring spontaneously in the fermentor(Solieri et al., 2010).The use of starter culture instead of native culture has been a widespread winemaking practice. Inoculated Malolactic fermentation increases the quality and safety of wine produced. On the other hand Spontaneous Malolactic fermentation sometimes increases wine spoilage and produces toxic metabolites like biogenic amines(Solieri et al. , 2010).EFFECTS OF MALOLACTIC FERMENTATIONThe main effects of Malolactic fermentation areAcidity reductionThe deacidification is due to the reduction of net concentration of carboxyl groups. The reduction in acidity is important for high acid wines and may not be desirable in wines already with lower acidity. There is a decrease in titratable acidity by 0.01 to 0.03 g/L because of hydrogen ion fixation(Kurane and Ghosh, 2012).Bacterial constancyFlavour changesVarious studies have reposted on the specific sensory changes that occurs in wine production due to the malolactic bacterial enzymatic activity. The sensory attributes are strain dependent. In addition to acidity reduction, flavour characteristics of wine after MLF can be buttery, nutty, earthy and fruity. The desired flavour profile in wine can occur in wine after MLF due to the removal of existing flavour compounds and production of new aromatic compounds with better sensory attribute. THE grape and yeast derived secondary m etabolites get modified to end products with better desired flavour compounds from metamorphosis of sugar and amino acids(Bartowsky, 2005).BASIC CONDITIONS NECESSARY FOR SUCCESSFUL MALOLACTIC FERMENTATIONpH MLF strains grow at pH 2.9-3.0. If the wines have a very low pH after the primary fermentation, it is required to consider the reduction of acidity before MLF initiation. It is also important to consider the formation of biogenic amines. MLF cultures grow well so far in pH higher(prenominal) than 3.5. Although the risk of off flavour and production of undesirable taste and aroma components increase as the pH increases. Therefore it is essential to adjust the acidity and pH before malolactic fermentation if the pH is more than 3.7. Malate is catabolised at pH 3.2 The enzymatic conversion of L-malic acid to L-lactic acid is faster at a pH 3.5 and the conversion rate is lower at lower pH values. The pH tolerance also relates to the strain variation and viability(Comfort, 2011).Te mperature Temperature is an important mover for initiation or inhibition of Malolactic fermentation. The ambient temperature for the growth of malolactic bacteria is between 20 to 37C. At a temperature below 15C, the Malolactic bacteria are generally non-viable. Therefore warming down the wines to 18C will allow the growth of lactic acid bacteria. Red wines at a higher temperature are suitable for MLF with general recommendations between 18 22C. In traditional winemaking regions, MLF is initiated in spring where the wines are monitored for the formation of L-Lactic acid bacteria and thus warming down the fermentor to ensure timely completion of MLF (LOUBSER, 2005).Free SO2 It is important to maintain Sulfur dioxide levels in malolactic fermentation. Sulfur dioxide is added to prevent formation of undesirable lactic acid bacteria. Most species of Lactic acid bacteria are more sensitive to Sulfur dioxide than Saccharomyces species. The free form of SO2 is responsible for inhibit t he undesirable lactic acid bacteria. The free SO2 is dependent on pH. The typical range of sulfite that is required needs to be added for white wines are 20-30 ppm and 30-50 ppm for red wines(LOUBSER, 2005). nutrient Composition Lactic acid bacteria are more specific than yeasts and require additional micronutrients and growth factors. Availability of nutrients is essential for the malolactic conversion. Compared to yeast lactic acid bacteria also requires presence of additional amino acids. At the end of alcoholic fermentation, yeasts release amino acids and thus there is no limitation of amino acids during MLF. Autolysis of yeasts also increases micronutrient concentration. It has been reported that malolactic fermentation occurs better during pre-yeast fermentation or after the release of amino acids. However it limits the MLF when the lactic acid bacteria is added during the alcoholic fermentation. There are mixtures of lactic acid nutrients available commercially and it is requ ired to time the addition of nutrients during the fermentation process(Torriani et al., 2011).Oxygen Oxygen stimulates MLF. It is one of the growth factor for lactic acid bacteria. However, the effect of oxygen varies with different species as few LAB get inhibited by oxygen. Oxygen level needs to be at a controlled level as higher oxygen level may sometimes lead to the production of acetic acid and undesirable end products. There have been occurrence of acetic acid accumulation in the wine when the Malolactic enzymatic activity occurs before the alcoholic fermentation. This is reported to occur aboard the aeration of juice or grape must(Comfort, 2011).CO2 Carbon dioxide stimulates MLF and helps with better vortex and mixing inside the fermentor. It also affects the buffering capacity of wine(Comfort, 2011).ADDRESSING ISSUES OF HIGHER OR LOWER acrimonious CONTENTHigh level of acidity often occur in grape musts that are derived from grapes grown in cooler regions like France, Germ any, cold regions of Australia. The wines made from these cold region vines, have improved flavour, microbial stability due to malolactic fermentation. Although sometimes the MLF may lead to excessive or lower acid content and sensory attributes(Massera et al., 2009). These issues can be addressed by two waysThe initial Malic acid level in the must needs to be estimated which will help choose specific maloalcoholic strains. with higher malic acid levels, maloalcoholic yeast strains works better in controlling the acidity level(Massera et al., 2009).There is another concern of development of excess diacetyl. The level of diacetyl increases by two metabolic pathways. One way they are formed is by metamorphosis of citric acid. Most wines have citric acid in them and some are produced even during primary fermentation. Hence by the end of Malolactic fermentation, the malic acid depletes and levels of diacetyl increase due to citric acid metabolism(Versari et al., 1999). During the citri c acid metabolism, acetic acid is also produced that contributes to volatile acidity. One of the way to tackle excess diacetyl is by using malolactic cultures that have lower citrate metabolism like Lalvin MT01. Another way of which excess diacetyl gets produced is when the malolactic bacteria metabolizes malic acid. For example, in dry wines sugars like pentoses can be metabolized by lactic acid bacteria but cannot be yeast fermentable. Diacetyl is produced when these sugars are metabolized. This can again be prevented with regular monitoring of malic acid levels and stabilize the process when they are reduced(Massera et al., 2009).During low acid conditions and high pH wines produced from warm climate vine, it is better to acidify the grape musts to favourable levels before primary fermentation. Malolactic fermentation of such low acid wines increases microbial stability and wine quality(LOUBSER, 2005).MLF MONITORINGAcidification of low acid musts is required for grapes and musts that are derived from vines of warm region. Adjusting pH and acidity before alcoholic fermentation is required. When Stronger acids like tartaric acid or DL- malic acid is used when the titratable acidity needs to be adjusted(Miller et al., 2011).Deacidification of musts with higher acid contentUsing engineered yeasts(Miller et al., 2011)CONCLUSIONTo obtain a desirable flavour profile through malolactic bacteria, various factors are needed to be considered and observed. Wine should be present at a temperature of more than 15C and nutrients can be supplemented during the fermentation process. Because sometimes high solid content may halt the fermentation of wine. It is better to rely on a Malolactic inoculum kind of than spontaneous initiation of Malolactic fermentation(Toit, 2011). The ethanol content should be regulated such that it does not inhibit the malolactic fermentation. It has been found that the lactic acid bacteria that grows in higher ethanol content will produce off fl avours and unwanted end products in the wine. To summarise it is known that MLF can be stimulated by low or no use of free sulfur dioxide, warm temperatures, supplementing nutrients to the culture, lowering the ethanol content, adjusting the level of acid and pH range.REFERENCESBARTOWSKY, E.

Neisseria gonorrhoeae Essay -- Essays Papers

Neisseria gonorrhoeae IntroductionNeisseria gonorrhoeae is the obligate human pathogen that causes the sexually transmitted disease (STD) gonorrhea. This Gram-negative diplococci/gonococci does non infect other animals or experimental animals and does not survive freely in the environment. The gonococcal infection occurs in the upper or lower tract, pharynx, ophthalmic area, rectum, and bloodstream. During the 1980s gonorrhea was also referred to as the clap when public awareness was quite minimal. This was one of the venereal diseases prostitutes hoped to contract since it resulted in infertility by pelvic inflammatory disease (PID). As documentation, diagnostic testing, and public awareness improved, there has been a decline in incidence reports, however, it is still considered a very common infectious disease. Encounter Sexually officious men and women of all races, ages, and socioeconomic backgrounds are susceptible to the gonococcal infection. However, out of the infected pop ulation, the CDC states 80% of the females and 10% of the males are asymptomatic. After incubation of five to seven days, males scarper to display symptoms of swelling in the urethra, painful and more frequent urination, and abnormal penal discharge of a thick yellow exudate (pus). Similarly, females experience continuing abdominal pain, inflammation of the cervix, painful urination, bleeding or irregular menstrual cycles, fever and increased vaginal yellow discharge. Females have a higher fortune factor of 60-90% of being infected after a single sexual encounter. Both sexes experience sore throat in oral infections if they are not asymptomatic. However, this response is most commonly mistaken as a viral sore throat.EntryNeisseria gonorrhoe... ...584.doi 10.1046/j.1462-5822.2002.t01-1- 00215.xPark, Hae-Sun Moon, Wolfgang, Matthew, van Putten, Jos P.

Compare Aeneas and Odysseus as Heroic Figures :: The Aenied, The Oddessy

Odysseus and Aeneas argon rattling alike in some ways and very different. They are both epic heroes except that one is Greek and the other is a Trojan. Odysseus is from the Greek tale The Oddessy, which was written by the famous Greek poet Homer. His call for is to find his way back home after a long journey. Aeneas is from the roman tale The Aenied, written by Virgil a famous Roman poet. Aeneass mission is to find a new home for him and his family. Both these characters had many similarities and differences in their ways of competitiveness.Both Odysseus and Aeneas were helped by different gods. Odysseus was helped by Calypso in a way. She held him captive, but was forced to release him from the father of all Greek gods,Zeus. Athena, goddess of wisdom, helped Odysseus find out whether or non Penelope still loved him, she clothed him to look like an old man so he could go into the town without people knowing who he was. He got help from the god of revolve as well who helpe d him by giving him a bag of wind so he could sail back to Ithaca. Poseidon did not really help Odysseus, he was just trying to convince him that he was nothing without the gods.Aeneas was never held captive by any of the gods as was Odysseus. Aeneas got help from Venus (Goddess of love), his mother. She convinced him to stop fighting because she wanted him to rescue his family which was a lot more important. Jupiter also helped him because Aeneass wife told Jupiter that Aeneas was going to kill himself, so she wanted him to send Aeneas a abridge telling him not to kill himself. Aeneas was going to do this because he found his father almost dead and decided to take his own life.Both of them are really great fighters, but they have differences in how they do things. Odysseus plans things out before he attacks and has a good plan as well. Aeneas however does not plan things out and just jumps right into things.

The Inevitability of Suffering in James Baldwins Sonnys Blues Essays

The Inevitability of Suffering in James Baldwins Sonnys Blues Everyone likes to heart safe. We try to protect ourselves and those we love, to make them feel safe as well. The idea conveyed about safety in James Baldwins Sonnys Blues is that there is no such(prenominal) thing. The narrator of this story had thought that his brother Sonny was safe. Or at least, that was what he had made himself believe. I told myself that Sonny was wild, but he wasnt crazy. And hed al expressions been a good male child, he hadnt ever turned hard or evil or disrespectful, the way kids can, so quick, so quick, especially in Harlem. I didnt requirement to believe that Id ever see my brother going down, coming to nothing, all that light in his face gone out, in the condition Id already seen so many others (48). But Sonny hadnt been safe from drugs, or the streets, or any of the things his brother had been sure he was immune to. He had been arrested for using and peddling heroin. Sonnys friend, the boy w e meet later, had thought the same thing as Sonnys brother had. I thought Sonny was a smart boy...too smart to get hung (49). But they were both wrong. It had been Sonnys brothers debt instrument to look out for Sonny from the time Sonny was born. When he started to walk, he walked from our mother straight to me. I caught him just before he fell when he took the first steps he ever took in this world (52). The narrator of the story is Sonnys big brother, so he feels responsible for him. This responsibility is confirmed by their mother on page 55, and the older brother reassures her, I wont let nothing happen to Sonny (57). But he fails at this, Sonny leaves and gets into trouble. mayhap the narrator felt that if he couldnt keep his brother safe,... ...fe. But he couldnt. And indeed, stupefying, lack of safety, is unavoidable, and also necessary for some things. When I was downstairs before, on my way here, listening to that woman sing, it struck me all of a sudden how much suffe ring she must have had to go through. Its repulsive to think you have to suffer that much (65). But we do. Everyone does. In fact, Theres no way not to suffer (65). We are never safe from it. Total safety is not attainable. Not except in Harlem, but everywhere, there are things that are simply not under our control. Try as we might to block out unpleasant things for those or so us, we cannot. This is the feeling that Baldwin creates through the story of Sonny and his brother. List of Work Cited Baldwin, James. Sonnys Blues. The Norton introduction to Fiction. 6th ed. Ed. Jerome Beaty.
