oxygen scavenger meaning in tamil

[116] Catalase is an unusual enzyme since, although hydrogen peroxide is its only substrate, it follows a ping-pong mechanism. [110] The mitochondrial isozyme seems to be the most biologically important of these three, since mice lacking this enzyme die soon after birth. and singlet oxygen scavenger (Galhano et al. எவ்வளவு கிளர்ச்சியூட்டுவதாக இருக்கிறது, தன் சொந்த ஆக்சிஜனைத் தயாரித்து, சுவாசிப்பதும். [65][66] The evolutionary reasons for this loss of urate conversion to allantoin remain the topic of active speculation. Hydrogen gas can be used for metallic ore subtractio… Also chemical inhibitors in the form of neutralizing amines are generally used. It often involves using a tinplate, broom, and bucket in hands. Activated charcoal is carbon that has been treated with oxygen.The treatment results in highly porous charcoal. [64] In almost all land animals, urate oxidase further catalyzes the oxidation of uric acid to allantoin,[65] but in humans and most higher primates, the urate oxidase gene is nonfunctional, so that UA is not further broken down. [85] Glutathione has antioxidant properties since the thiol group in its cysteine moiety is a reducing agent and can be reversibly oxidized and reduced. [133] Glutathione peroxidase 1 is the most abundant and is a very efficient scavenger of hydrogen peroxide, while glutathione peroxidase 4 is most active with lipid hydroperoxides. Tamil Nadu topped the chart while Gujarat stood second in terms of sewer deaths. (Source: MGH). d Department of Mathematics, ... besides being effective active oxygen species scavengers and lipid peroxidase inhibitors. [153][154] Although large amounts of sulfur-containing amino acids such as acetylcysteine can increase glutathione,[155] no evidence exists that eating high levels of these glutathione precursors is beneficial for healthy adults. [113], Catalases are enzymes that catalyse the conversion of hydrogen peroxide to water and oxygen, using either an iron or manganese cofactor. [citation needed], Antioxidants are frequently added to industrial products. [50], The relative importance and interactions between these different antioxidants is a very complex question, with the various antioxidant compounds and antioxidant enzyme systems having synergistic and interdependent effects on one another. Solid polymer products start to crack on exposed surfaces as the material degrades and the chains break. As with antioxidant metabolites, the contributions of these enzymes to antioxidant defenses can be hard to separate from one another, but the generation of transgenic mice lacking just one antioxidant enzyme can be informative. Oxygen Scavenger Os1l; Sulfonated Asphalt +22 more products +View All. [148] The effects of cooking and food processing are complex, as these processes can also increase the bioavailability of antioxidants, such as some carotenoids in vegetables. [95] GPx4 is the only known enzyme that efficiently reduces lipid-hydroperoxides within biological membranes. [90][91] Of these, α-tocopherol has been most studied as it has the highest bioavailability, with the body preferentially absorbing and metabolising this form.[92]. We are only now beginning to appreciate how strange and splendid it is, how it catches the breath, the loveliest object afloat around the sun, enclosed, bubble of atmosphere, manufacturing and breathing its own, , fixing its own nitrogen from the air into, its own weather at the surface of its rain forests, constructing its own carapace from living parts: chalk cliffs, coral reefs, fossils from earlier forms of life now covered by layers of new life meshed together around the globe.”. [118][119], Peroxiredoxins are peroxidases that catalyze the reduction of hydrogen peroxide, organic hydroperoxides, as well as peroxynitrite. [140][141], The most common molecules attacked by oxidation are unsaturated fats; oxidation causes them to turn rancid. However, the roles and importance of the various forms of vitamin E are presently unclear,[96][97] and it has even been suggested that the most important function of α-tocopherol is as a signaling molecule, with this molecule having no significant role in antioxidant metabolism. தன் சொந்த நைட்ரஜனை எடுத்து தன் சொந்த மண்ணுக்குள் நிலைப்படுத்துவதும், சொந்த வானிலையை உருவாக்குவதும், சுண்ணாம்புப் பாறைகள், பவளப்பாறைகள், உலகெங்கும் புதிய உயிரிகளால் ஒன்றுசேர்ந்து பின்னப்பட்ட அடுக்குகளால் தற்போது மூடப்பட்டிருப்பவற்றின் பண்டைய உயிர் வகைகளின் புதைப்படிவங்கள் ஆகியவற்றிலிருந்து தன் சொந்த மேலோட்டை உருவமைப்பதும், தன் சொந்த நீல குமிழ் போன்ற வளிமண்டலத்தால் சூழப்பட்டிருப்பதும், சூரியனைச் சுற்றி மிதந்துவருவதுமான மிக அழகிய அந்தப் பொருளை நாம் இப்போதுதான் மதித்துணர ஆரம்பித்திருக்கிறோம்.”, scrap metal are dumped into a 30-foot [9 m]-tall pear-shaped vessel known as the basic, கவனமாக பிரித்தெடுக்கப்பட்ட 90 டன் உலோக கழிவுத்துண்டுகள், அடிப்படை, ஊதுலை என அழைக்கப்படும் 9 மீட்டர் உயரமுள்ள பேரிக்காய் வடிவ. [32] The different antioxidants are present at a wide range of concentrations in body fluids and tissues, with some such as glutathione or ubiquinone mostly present within cells, while others such as uric acid are more evenly distributed (see table below). About 50 billion single-use plastic water bottles made of polyethylene terephthalate (PET) are produced in the United States each year, and most are discarded. They can be protected by antiozonants. தயாராக வைக்கப்பட்டிருந்தாலும் ரயில் அதிக உயரத்தை அடைவதால் அந்தப் பெட்டிகளுக்குள்ளேயும் காற்று பம்ப் செய்யப்படுகிறது. Edible food packaging. This detoxification pathway is the result of multiple enzymes, with superoxide dismutases catalysing the first step and then catalases and various peroxidases removing hydrogen peroxide. Monocytes compose 2% to 10% of all leukocytes in the human body and serve multiple roles in immune function. Corrosion is a natural process driven by energy consideration. [78] Ascorbic acid is required for the conversion of the procollagen to collagen by oxidizing proline residues to hydroxyproline. The oxygen level below 95 per cent indicates that there is a lung problem. By using our services, you agree to our use of cookies. [73] By itself, UA-related risk of gout at high levels (415–530 μmol/L) is only 0.5% per year with an increase to 4.5% per year at UA supersaturation levels (535+ μmol/L). [67][68] The antioxidant effects of uric acid have led researchers to suggest this mutation was beneficial to early primates and humans. Manual Scavenging --Picking up the trash of the world. உள்ளே இழுத்து கார்பன்-டைஆக்சைடை வெளியே விடுகின்றனர். oxygen scavenger ...

Indonesian Italian Korean Latin Latvian Macedonian Norwegian Polish Portuguese Romanian Russian Serbian Slovak Spanish Swahili Swedish Tamil Turkish Vietnamese Welsh. Thus, these foods are rarely preserved by drying; instead, they are preserved by smoking, salting or fermenting. The holiday season is in full swing, and with it comes time for family celebration while gathering around tables full of delicious foods with seasonal spices! சேமித்து வைக்கும் ஒரு ரசாயனம் இருக்கிறது. It has been claimed that the α-tocopherol form is the most important lipid-soluble antioxidant, and that it protects membranes from oxidation by reacting with lipid radicals produced in the lipid peroxidation chain reaction. n. 1. [159], Alternative in vitro measurements of antioxidant content in foods – also based on the presence of polyphenols – include the Folin-Ciocalteu reagent, and the Trolox equivalent antioxidant capacity assay. The trial was blinded, meaning that neither the volunteers nor the people running the trial knew who got what. 2011). Heavy metal stress also increased the level of proline in Spirulina platensis-S5 (Choudhary et al. [32] The amount of protection provided by any one antioxidant will also depend on its concentration, its reactivity towards the particular reactive oxygen species being considered, and the status of the antioxidants with which it interacts.[32]. A paradox in metabolism is that, while the vast majority of complex life on Earth requires oxygen for its existence, oxygen is a highly reactive element that damages living organisms by producing reactive oxygen species. துருப்பிடிக்க விடாமல் ஹீமோகுளோபின் மூலக்கூறு அதை எப்படி ஆக்சிஜனோடு இணைக்கிறது, அல்லது பிரிக்கிறது? For example, ubiquinol (coenzyme Q) is poorly absorbed from the gut and is made through the mevalonate pathway. அது எவ்வளவு விநோதமானதும் சிறந்ததுமாக இருக்கிறது. Find here Boiler Chemicals, Chemical Boiler manufacturers, suppliers & exporters in India. However, as oxygen is also important for plant respiration, storing plant materials in anaerobic conditions produces unpleasant flavors and unappealing colors. scavenger synonyms, scavenger pronunciation, scavenger translation, English dictionary definition of scavenger. வளர்சிதை வினை மாற்றத்தால் இயக்கப்படுபவை இவை. [51][52] The action of one antioxidant may therefore depend on the proper function of other members of the antioxidant system. [124] Peroxiredoxins seem to be important in antioxidant metabolism, as mice lacking peroxiredoxin 1 or 2 have shortened lifespan and suffer from hemolytic anaemia, while plants use peroxiredoxins to remove hydrogen peroxide generated in chloroplasts. [63] Another example is glutathione, which is made from amino acids. Any remaining oxygen can be dealt with the use of chemical oxygen scavenger such as catalyzed sodium sulphite; CO2 is normally controlled by an aerator or decarbonator. It is not ordinary water composed of two parts hydrogen and one part. Learn more. அந்தத் தண்ணீர் இரண்டு பங்கு ஹைட்ரஜனும், ஒரு பங்கு ஆக்சிஜனும் சேர்ந்த சாதாரண தண்ணீர் அல்ல. [142] Since oxidized lipids are often discolored and usually have unpleasant tastes such as metallic or sulfurous flavors, it is important to avoid oxidation in fat-rich foods. [157][158] Earlier measurements and ratings by the United States Department of Agriculture were withdrawn in 2012 as biologically irrelevant to human health, referring to an absence of physiological evidence for polyphenols having antioxidant properties in vivo. As Water Creation It is mainly used to create water. [41] Peroxide is also produced from the oxidation of reduced flavoproteins, such as complex I. Oxygen scavengers: The presence of oxygen in the package can generate oxidative reactions and result in food deterioration. [27] Record the pronunciation of this word in your own voice and play it to listen to how you have pronounced it. Plants, such as Arabidopsis thaliana, have a particularly great diversity of isoforms. is discharged into body tissue, sustaining the life of the cells. There are two views about location of leghaemoglobin that is either located outside the peribacteroid membrane or located in between bacteroids. 2. Reactive oxygen and nitrogen species scavenging activity of Psidium guajava (l) leaf S.Thenmozhi and S. Rajan* Department of Microbiology, M. R. Government Arts College, Mannargudi, Thiruvarur District, Tamil Nadu, S. India *Corresponding author ABSTRACT Introduction Reactive oxygen species (ROS) are Conversely antioxidants are believed to be protective. Even less fatty foods such as fruits are sprayed with sulfurous antioxidants prior to air drying. Oxidation and UV degradation are also frequently linked, mainly because UV radiation creates free radicals by bond breakage. Conference Proceeding International Seminar on Dia-Fest 2014 Role of Antioxidants on Reducing Reactive oxygen species In Diabetic Patients S. Merish1, V. Ponnaiya2, M. Tamizhamuthu3, M. Dhivya4, A.

[79][80] Ascorbic acid is a redox catalyst which can reduce, and thereby neutralize, reactive oxygen species such as hydrogen peroxide. Uric acid is by far the highest concentration antioxidant in human blood. −). [76] In other cells, it is maintained in its reduced form by reaction with glutathione, which can be catalysed by protein disulfide isomerase and glutaredoxins. Particularly important is the ability to sequester iron, which is the function of iron-binding proteins such as transferrin and ferritin. Corrosion inhibitors have been frequently studied, since they offer simple solution for protection of metals against corrosion in aqueous environment. [88][89], Vitamin E is the collective name for a set of eight related tocopherols and tocotrienols, which are fat-soluble vitamins with antioxidant properties.

Woodward award. Here's the word you're looking for. [46] This effect is partly offset by the involvement of carotenoids in photoinhibition, and in algae and cyanobacteria, by large amount of iodide and selenium,[47] which involves these antioxidants reacting with over-reduced forms of the photosynthetic reaction centres to prevent the production of reactive oxygen species. is available to serve this vital purpose. We have know about Nitrogen for Plantsnow let’s discuss the hydrogen uses in everyday life. தமிழ் அகராதி Provides meaning in tamil for english , tamil and other language. [75], Ascorbic acid or vitamin C is a monosaccharide oxidation-reduction (redox) catalyst found in both animals and plants. Learn more. cells, and even hunt down and destroy viruses, bacteria, and other infectious agents. Other polymers susceptible to oxidation include polypropylene and polyethylene. Read the first two parts here and here.. Chennai: When the Prohibition of Employment as Manual Scavengers … For example, vitamin C has antioxidant activity when it reduces oxidizing substances such as hydrogen peroxide;[101] however, it will also reduce metal ions that generate free radicals through the Fenton reaction. Oxidation is often catalyzed by metals, which is why fats such as butter should never be wrapped in aluminium foil or kept in metal containers. அப்படியிருக்க, எங்கும் நீர் மயமாயுள்ள ஒரு சூழலில் இருக்கிற இரத்தச் சிவப்பணுவில். for even a few seconds, delicate neuron functions are impaired. [84] In some organisms glutathione is replaced by other thiols, such as by mycothiol in the Actinomycetes, bacillithiol in some Gram-positive bacteria,[86][87] or by trypanothione in the Kinetoplastids. A mixture of oxygen and other gases, administered to a patient to help him or her to breathe. [162], Early research on the role of antioxidants in biology focused on their use in preventing the oxidation of unsaturated fats, which is the cause of rancidity. In food science analyses in vitro, the oxygen radical absorbance capacity (ORAC) was once an industry standard for estimating antioxidant strength of whole foods, juices and food additives, mainly from the presence of polyphenols. மூளையின் ஏதாவது ஒரு குறிப்பிட்ட பகுதிக்கு சில வினாடிகளே. Mineral acids like hydrochloric and sulfuric acids are most widely used … 2007). transport to tissues, wound healing, and ‘nutritional value’ of blood are being abandoned. [106], Superoxide dismutases (SODs) are a class of closely related enzymes that catalyze the breakdown of the superoxide anion into oxygen and hydrogen peroxide. Moringa derivated from a Tamil word, murungai has the meaning of twisted pod [5]. டாங்க் இருக்கிறது. a nonmetallic bivalent element that is normally a colorless odorless tasteless nonflammable diatomic gas; constitutes 21 percent of the atmosphere by volume; the most abundant element in the earth's crust. [84] It is not required in the diet and is instead synthesized in cells from its constituent amino acids. To protect these enzymes, nodule contains an oxygen scavenger called leghaemoglobin (Lb), which is a reddish-pink pigment. [145], Antioxidant polymer stabilizers are widely used to prevent the degradation of polymers such as rubbers, plastics and adhesives that causes a loss of strength and flexibility in these materials. The evolution of angiosperm plants between 50 and 200 million years ago resulted in the development of many antioxidant pigments – particularly during the Jurassic period – as chemical defences against reactive oxygen species that are byproducts of photosynthesis. [citation needed], As with the chemical antioxidants, cells are protected against oxidative stress by an interacting network of antioxidant enzymes. Some fatty foods such as olive oil are partially protected from oxidation by their natural content of antioxidants, but remain sensitive to photooxidation. There are several types of gas based on its usage and properties, there are so many of them that we can only discuss one type of gas. Tags: Monocyte meaning in Hindi. [163] Antioxidant activity could be measured simply by placing the fat in a closed container with oxygen and measuring the rate of oxygen consumption. , நைட்ரஜன், பிற வாயுக்களால் பூமியை சுற்றியிருக்கும் ஒரு புடவை—சூரியனுடைய வெப்பத்தில் கொஞ்சத்தைப் பிடித்துவைத்து மீதியை தப்பவிடுகிறது. atherosclerosis and ischemic stroke is considered above. [136] These enzymes are at particularly high levels in the liver and also serve in detoxification metabolism. [83], Glutathione is a cysteine-containing peptide found in most forms of aerobic life. A chemical element (symbol O) with an atomic number of 8 and relative atomic mass of 15.9994. [71] Uric acid's antioxidant activities are also complex, given that it does not react with some oxidants, such as superoxide, but does act against peroxynitrite,[72] peroxides, and hypochlorous acid. [84][132] Glutathione peroxidase is an enzyme containing four selenium-cofactors that catalyzes the breakdown of hydrogen peroxide and organic hydroperoxides. These substances include fried foods, alcohol, tobacco smoke, pesticides and air pollutants. [citation needed], That is, paradoxically, agents which are normally considered antioxidants can act as conditional pro-oxidants and actually increase oxidative stress. According to Dr. Kumar, the normal blood oxygen saturation level for someone who is healthy will be around 95–100 per cent. Pokorny, Jan, Nelly Yanishlieva, and Michael H. Gordon, This page was last edited on 2 February 2021, at 17:48. [129] The active site of thioredoxin consists of two neighboring cysteines, as part of a highly conserved CXXC motif, that can cycle between an active dithiol form (reduced) and an oxidized disulfide form. [114][115] This protein is localized to peroxisomes in most eukaryotic cells. [100], Antioxidants that are reducing agents can also act as pro-oxidants. அடர் நிறம் கொண்ட தசைநார்களோ மெதுவாக சுருங்குபவை. நிலத்தில் “டைவ்” அடிக்கும்போது, இவற்றின் வாய், செவுள் அறைகள் முழுவதும் நீர் நிரம்பி இருக்கும். [144] In 2014, the worldwide market for natural and synthetic antioxidants was US$2.25 billion with a forecast of growth to $3.25 billion by 2020. Meaning of esperamicin. [150], Other antioxidants are not obtained from the diet, but instead are made in the body. [70], Uric acid has the highest concentration of any blood antioxidant[58] and provides over half of the total antioxidant capacity of human serum. Antioxidants are an especially important class of preservatives as, unlike bacterial or fungal spoilage, oxidation reactions still occur relatively rapidly in frozen or refrigerated food. However, when any limited part of the brain is deprived of. Do you think a simple flush button or any toilet cleaner make it clean?

Information and translations of esperamicin in the most comprehensive dictionary definitions resource on the web. [146] Polymers containing double bonds in their main chains, such as natural rubber and polybutadiene, are especially susceptible to oxidation and ozonolysis. A patient at rest uses only 25 percent of the, ஒரு நோயாளி ஓய்வெடுக்கையில் அவருடைய இரத்தத்திலுள்ள, The darker muscle fibers are slow-contracting, or slow-twitch, fibers, and they are driven by. [76][81] In addition to its direct antioxidant effects, ascorbic acid is also a substrate for the redox enzyme ascorbate peroxidase, a function that is used in stress resistance in plants. [108] There also exists a third form of SOD in extracellular fluids, which contains copper and zinc in its active sites. [143] Antioxidant preservatives are also added to fat based cosmetics such as lipstick and moisturizers to prevent rancidity. Inhibition is a preventive measure against corrosive attack on metallic materials. One example is made based on the seaweed, Eucheuma cottonii. இந்த முக்கிய நோக்கத்தைச் சேவிக்கக் கிடைக்கிறது. These cells are scavengers that phagocytose whole or killed microorganisms and are…. [123] Over-oxidation of this cysteine residue in peroxiredoxins inactivates these enzymes, but this can be reversed by the action of sulfiredoxin. [138] Consequently, packaging of fresh fruits and vegetables contains an ~8% oxygen atmosphere. [94] This is in line with findings showing that α-tocopherol, but not water-soluble antioxidants, efficiently protects glutathione peroxidase 4 (GPX4)-deficient cells from cell death. What does esperamicin mean? The free radicals then react with oxygen to produce peroxy radicals which cause yet further damage, often in a chain reaction. These tiny holes give the charcoal a surface area of 300-2,000 m 2 /g, allowing liquids or gases to pass through the charcoal and interact with the exposed carbon. An animal, such as a vulture or housefly, that feeds on dead or decaying matter. இந்த. [64] Concerns over elevated UA's contribution to gout must be considered as one of many risk factors. Cookies help us deliver our services. [111] In contrast, the mice lacking copper/zinc SOD (Sod1) are viable but have numerous pathologies and a reduced lifespan (see article on superoxide), while mice without the extracellular SOD have minimal defects (sensitive to hyperoxia). molecule manage to combine and uncombine iron and. ABSTRACT: Reactive Oxygen Species are widely believed to be involved in the etiology of many diseases as indicated by the sign of oxidative stress seen in those diseases. Besides ascorbate, medically important conditional pro-oxidants include uric acid and sulfhydryl amino acids such as homocysteine. It is facilitated by the concerted actions of bacterial, fungal, insect, and scavenger agents over time, until the body is stripped of all soft tissue and only the skeleton remains. அளவு குறைவாக இருந்ததால், நடக்கும் தொலைவில் தான் அவை உள்ளன. This reaction produces oxidised α-tocopheroxyl radicals that can be recycled back to the active reduced form through reduction by other antioxidants, such as ascorbate, retinol or ubiquinol. Define scavenger. In the late 19th and early 20th centuries, extensive study concentrated on the use of antioxidants in important industrial processes, such as the prevention of metal corrosion, the vulcanization of rubber, and the polymerization of fuels in the fouling of internal combustion engines. in limited supply, KIPP there really did most of the legwork. [166] Research into how vitamin E prevents the process of lipid peroxidation led to the identification of antioxidants as reducing agents that prevent oxidative reactions, often by scavenging reactive oxygen species before they can damage cells. The potential role of the pro-oxidant role of uric acid in (e.g.) ஏனென்றால் ஆக்ஸிஜனையும் ஊட்டச் சத்துக்களையும் கொண்டு சென்ற தொப்புள்கொடி இப்போது இல்லை. [90][93] This removes the free radical intermediates and prevents the propagation reaction from continuing. [102] However, less data is available for other dietary antioxidants, such as vitamin E,[103] or the polyphenols. [48][49], Antioxidants are classified into two broad divisions, depending on whether they are soluble in water (hydrophilic) or in lipids (lipophilic). oxygen translation in English-Tamil dictionary. [82] Ascorbic acid is present at high levels in all parts of plants and can reach concentrations of 20 millimolar in chloroplasts. [164][165] The possible mechanisms of action of antioxidants were first explored when it was recognized that a substance with anti-oxidative activity is likely to be one that is itself readily oxidized. in the watery environment of the red blood cell without producing rust? Halliwell, Barry. Chennai, Tamil Nadu. [42] However, although these enzymes can produce oxidants, the relative importance of the electron transfer chain to other processes that generate peroxide is unclear. [130] After being oxidized, the active thioredoxin is regenerated by the action of thioredoxin reductase, using NADPH as an electron donor. A common use is as stabilizers in fuels and lubricants to prevent oxidation, and in gasolines to prevent the polymerization that leads to the formation of engine-fouling residues. Here I would like to describe one gas that is hydrogen that has so many applicable usage and properties for corporation and people’s lives. Molecular oxygen (O2), a colorless, odorless gas at room temperature. Oxygen scavengers remove oxygen thereby retarding oxidative reactions. அவை சின்னஞ்சிறியவையாய் இருப்பதால், இரத்த நுண்குழாய்கள் வழியாகப் பயணித்து இரத்த சிவப்பணு குறைவுபடும் திசுக்களில், செலுத்துவதற்குப் பயன்படுத்தப்படலாம்; இரத்த நாளங்களில் உள்ள தடைகளையும் மூளை செல்களிலுள்ள, கோளாறுகளையும் நீக்குவதற்கு உபயோகப்படுத்தப்படலாம்; வைரஸ். [128] Proteins related to thioredoxin are present in all sequenced organisms. [125][126][127], The thioredoxin system contains the 12-kDa protein thioredoxin and its companion thioredoxin reductase. necessary to pump air into the compartments, which are also equipped with, ஏற்கெனவே ரயில்பெட்டியில் ஒவ்வொரு பயணிக்கென்றும். The mode of cracking varies between oxygen and ozone attack, the former causing a "crazy paving" effect, while ozone attack produces deeper cracks aligned at right angles to the tensile strain in the product. Manual scavenging is prohibited by the “Prohibition of Employment As Manual Scavengers And Their Rehabilitation Act, 2013”. Here's the word you're looking for. [159] Consequently, the ORAC method, derived only from in vitro experiments, is no longer considered relevant to human diets or biology, as of 2010. [79] Due to its high concentration and its central role in maintaining the cell's redox state, glutathione is one of the most important cellular antioxidants. Uric acid (UA) is an antioxidant oxypurine produced from xanthine by the enzyme xanthine oxidase, and is an intermediate product of purine metabolism. , செவுள் அறைகள் முழுவதும் நீர் நிரம்பி இருக்கும் did most of the world our use of cookies பம்ப் செய்யப்படுகிறது part...
