The trickle irrigation system has the possible to increase the agricultural productiveness and besides to cut down H2O use required for irrigation. It is a system of pipes and tubing located under the dirt. We will write a custom essay sample on How Effective Are Drip Irrigation Systems Environmental Sciences Essay or any similar topic only for you Order Now Water is passed through these pipes which end at near the roots of the workss. This makes the H2O loss minimal. Initial phase is planing the system and its installing follows it. The article states the advantages and disadvantages of the system and besides cites grounds with respect to the societal, economic and environmental facets. Poverty is one of the primary concerns the universe faces in its route to development. Eradication of poorness tends to be the premier purposes of authoritiess worldwide. Lack of proper nutrition is a major cause lending to poverty. Bettering agricultural criterions can assist in bring forthing more nutrient and therefore counter the deficiency of nutrient factor. One manner to better agricultural criterions is to develop the irrigation methods used. Irrigation is closely related to poorness. Irrigation benefits the hapless through higher production, higher outputs, low hazard of harvest failure and higher and twelvemonth unit of ammunition farm and non-farm employment. Irrigation leads to high value market oriented agricultural production [ 1 ] . However, in developing states like India, the agricultural sector is to a great extent dependent on the south-west monsoons. In position of the lifting temperatures worldwide due to planetary heating and alterations of conditions forms asso ciated with it, dependance on rains is non ever a possible solution. Failure of proper rains can stultify the agricultural sector which can take to an overall rise in poorness. Thus efficient methods of irrigation demand to be developed. The trickle irrigation system is one such method of irrigation that is being utilized. Drip irrigation is H2O salvaging, efficient and effectual lacrimation system.The article focuses on the different facets of the trickle irrigation system, its part in poorness relief and the societal economic and environmental impacts of this engineering. Subsurface trickle irrigation or SDI is another manner of terming a trickle irrigation system. As stated by C. Shock, trickle irrigation is the slow even application of low-pressure H2O to dirt and workss utilizing plastic tube placed near the workss A ; acirc ; ˆâ„ ¢ root zone [ 8 ] . Water is supplied to the dirt at really low rates from the system of the plastic tube pipes which are fitted with emitters at the terminals. Therefore loss of H2O through vaporization, H2O run-off and infiltration is minimized to a great extent. Besides H2O contact with the roots, foliages and fruits of the works is reduced which helps in bar of formation of disease on the works. Since the tube is buried under the dirt, it is less at hazard of harm due to weeding and cultivation activities. Planing a subsurface trickle system requires an experient qualified interior decorator. As G. Harris has stated, proper hydraulic design is the initial measure in put ining a successful SDI system [ 5 ] . This will guarantee that the system effectively trades with the restraints imposed by the harvest and dirt features, field size, topography, H2O supply and form. The system must be capable of run intoing the harvest H2O demand during the peak H2O demand times. A block or zone, which is the part of the field that can be watered at the same clip, is determined by the features of the trickle tube selected. The optimum tubing spacing is determined by the dirt features and the deepness of tube arrangement. If the installings are excessively deep it will curtail the handiness of surface applied foods limits the effectivity of the system for harvest sprouting. Adequate blushing speeds must be allowed for in the design to take deposits from the emitters. This helps to forestall the SDI syst em from acquiring clogged and increases the system A ; acirc ; ˆâ„ ¢s life. Following the planing comes the installation portion of the SDI system. Proper installing ensures that the system performs optimally and it besides determines the life of the system. Installation is done in sites which have non been cropped late as insect activity or weedy countries could destruct the pipes within yearss of installing [ 6 ] .Initially location of the tube is marked out. A subsoiler can be used or if more accurate placement is needed, GPS can besides be used. Specialized injectors are available for installing of the SDI pipes. The power and H2O beginning restrictions are to be considered during the installing of the system. Filters are besides used which helps in taking atoms and keeps the emitters from acquiring clogged. The major characteristic of this system that makes it extremely desirable is that the H2O usage efficiency will be better compared to other systems or methods of irrigation. Evidence put frontward by C.R. Camp show that drip irrigation systems implemented in Virginia require 30 % less H2O compared to sprinkler irrigation for cultivating maize [ 3 ] . For cotton, the H2O use was reduced significantly by 40 % . Execution of the system in Hawaii helped the husbandmans to acquire a greater output than when utilizing sprinkler irrigation system [ 4 ] . Extra advantages include: Drip irrigation systems are suited to farms holding uneven topography or dirt texture. Precise application of foods is possible. Timely application of weedkillers, insect powders and antifungals is possible. The trickle irrigation system can be automated. Irrigation can be carried out twenty-four hours and dark regardless of the air current, daylight handiness or other cultivation activities [ 7 ] . The SDI system can be used for fertilising. Foods can be supplied in a sustained manner, and regulated in rate and composing, harmonizing to the harvest demands [ 7 ] . The fluid mechanicss help in easy H2O command the figure of points provides first-class uniformity of supply. There are a figure of disadvantages for the trickle irrigation system. Initial investing is rather high for this system. Root development is limited and therefore ensuing in root putrefaction and dust jobs [ 7 ] . The emitters can acquire clogged often and cleaning it is a dearly-won and clip devouring procedure. Accretion of salts might happen at the interface between the moisture and dry zones of the dirt. It is by and large accepted that irrigation can transform society every bit good as land and landscapes. Drip irrigation has brought about a figure of positive and negative societal impacts. It helps in relieving poorness in irrigated countries, minimizes the differential distribution of benefits across husbandmans and increases the societal benefits [ 7 ] . The positive consequence it has brought on the demographics of the Waitaki vale has helped collar the population diminution [ 9 ] . The extra population would non merely beef up the societal construction and webs but besides increase economic growing. Thus services such as wellness and instruction would go more feasible. On the other manus, automated drip irrigation systems tend to necessitate less labour and in low pay economic systems, where occupation chances lag behind growing in labour force owing to lift in population, cut downing hired labors can be socially debatable [ 10 ] . This leads to farther unemployment. Sing the economic facets, drip irrigation systems have helped husbandmans to achieve better net incomes due to higher output. Farmers can conserve H2O more and besides increase the productiveness of their farms. The output of cotton increased by 21 % in Dalby and Moree while in Lucerne, output betterment was between 13-34 % [ 5 ] . The net incomes obtained in tomato cultivation in California were approximately 867 to 1493 dollars more [ 12 ] . Water use was reduced by 45 % for maize cultivation in the Great Plains in USA [ 13 ] . In malice of all these a major hinderance in the execution of the system is the high initial cost. Designing and installing requires qualified people and moreover the cost and clip for care of the system is besides on the higher side. However in the long tally husbandmans can do up for the high initial costs with the higher sum of output they obtain. The trickle irrigation helps in bettering the dirt surface and the environment. It allows pre treated coalbed methane Waterss to flux into the root zone of an agricultural field which minimized environmental impacts by hive awaying damaging salts in the vadose zone [ 11 ] . It reduces off-farm motions of fertilisers and pollutants and improves the H2O usage efficiency of irrigated agribusiness [ 3 ] . It offers possible for increased H2O and nitrate fertiliser efficiency and decreases land H2O taint by NO3 [ 14 ] . The certain negative traits that the system has on the environment are that root putrefaction may happen and degrees of salt rises. Root development is affected taking to deficient protection against deficiency of H2O and hapless root anchorage [ 7 ] . Overall, the trickle irrigation system is an effectual manner of irrigation. It saves on H2O use and allows husbandmans to increase their farm end product. The increased end products helps counter the rise in nutrient demand and helps the poorer subdivisions of the society with more nutrient at cheaper monetary values. Evidence presented in the article show the increased harvest output. Even thought the engineering comes at a higher monetary value, the effects of implementing it will be long lasting and positive.

Influence analyses of the community support - Myassignmenthelp.Com

Question: Discuss about theInfluence analyses of the community support. Answer: Introduction Field Trips are crucial since they not only bridge the gap between hand-on experience and education, but also allow an individual to collect information about realities of tourism management. Tourism, being a globally competitive industry, majority of the countries across the world is trying to fetch tourists from both homeland and abroad (McCrea Walters, 2012). Being an eye catching place for tourism, South Bank attracts a vast amount of tourists. In this report, two of the major sustainability management issues of the tourism industry have been discussed and necessary recommendations are provided to overcome these issues. Along with this, a summary reflection of the whole trip is provided in this report. Discussion Sustainability management issues One of the major issues faced by entire Brisbane including South bank is the increased Green house gas emission. South bank is currently facing issues due to excessive green house gas emission, which in turn has increased the overall consumption of electricity and water along with an increased generation of waste (Brisbane Regional Tourism Investment and Infrastructure Plan., 2018). As a result, both residents of South Bank and the tourists who have come to visit the city are facing issues like lack of power supply. This problem associated with water and power supply of the eye catching destination, can be considered as the potential threat to the tourism industries of South Bank. Hence South Bank requires alternative water and power source for both residents and tourist retention (Annual Reports., 2018). Although the excessive emission of green house gas has become high concern to the citizens of Brisbane, the government is giving less attention to issue. Due to High Green house gas emission, South Bank is suffering from climate change, increased temperature sea-level and various weather events like floods, storms and droughts. These issues are resulting in various tropical diseases and all these issues are imposing negative impact on livelihood, infrastructure, housing facilities and basic service provided to the tourists (Subtropicaldesign.org.au., 2018). The popular destination is also suffering from carrying capacity issues due to overcrowding specially during the weekends in popular areas like Street Beach (Brisbane Regional Tourism Investment and Infrastructure Plan., 2018). The daily crowd of visitors, both local and international has crossed the carrying capacity of South Bank. Besides that, lack of enough picnic tables, barbeques, parking areas and restaurants that are required for the vast number of people arriving at South Bank is imposing negative impact on the tourist retention. Tourists are compelled to leave the destination due to the above mentioned issues. Excessive overcrowding is resulting in increment of congestion level and this in turn is imposing negative impact on local people and residents of the city (Hunter, 2012). This issue of overcrowding in South Bank leads to lack of dwelling and basic facilities like proper sewage system, drinking water and washing clothes. Improper infrastructure also results in various health issues like skin infection, rheumatic fever, eye infection and others (About South bank, 2018). Both adults as well as children are the victims of these issues which includes lack of proper water supply and sanitation (Page, 2014). Figure 1: Overcrowded South Bank Recommendations about tourism stakeholder responses necessary for sustainability Both Public and Private Institutions of South Bank associated with tourism planning, should use scientific methods and equipments to deal with the above mentioned issues (Buckley, 2012). Considering the fact that tourism stakeholders at South Bank are taking several initiative to improve and increase the sustainability of the city, several recommendations are given for further improvement of the situation (Newsome, Moore Dowling, 2012). Minimization of yearly Greenhouse emission along with minimization of electricity usage by eliminating unnecessary use of electricity is needed to be performed (Mason, 2015). Greenhouse Gas emission in South Bank can be treated by conduction of integrated green infrastructure and green technology. Usage of various equipments to support the outcome of low carbon is required (Liu et al., 2014). Recycling of both liquid and solid waste materials along with more usage of public transport in order to reduce the pollution is highly necessary (Lee, 2013). Initiatives should be taken to make the citizens understand the hazardous results of Greenhouse Gas by holding several numbers of surveys and campaigns along with giving stress over the usage of bicycles instead of cars in order to reduce air pollution (Day, 2012). According to report, the department of Sustainability Reduction has installed photovoltaic system in about 80 schools that are under the program of solar schools in order to reduce greenhouse gas emission. Brisbane has also taken initiative to install the Ergon protection (Farine et al., 2012). Apart from this, tourism stakeholders and stakeholders of leisure industries are also recommended to install smart meters along with the conduction of detailed consumption analysis to help the government to track the amount of energy saved per year. In order to resolve the issues due to overcrowded destination, both restaurants and museums should be managing the tourists by providing information about the availability of the vacant places (Ganis, Minnery Mateo-Babiano, 2014). The destination management organization should maintain transparency while booking airline seats or hotel rooms for the tourists. In order to resolve the accommodation problem, more picnic tables and barbeque setups should be constructed in order to retain tourist at South Bank (Nunkoo, Ramkissoon Gursoy, 2013). Another major step that can be taken by the stakeholders is to build transparency while booking rooms at South Bank by priory informing them about the number of rooms available at the destination. This will help the tourists to avoid visiting the destination when no rooms are available (Lucas et al., 2013). This whole method will eventually prevent overcrowding at South Bank. Conclusion From the above report, it can be concluded that, though several steps are already been taken to prevent the excessive emission of green house effect and overcrowding of the destination, in order to fully eradicate the problems, the suggested recommendations should be implemented. It can be clearly understood that only the government or tourism stakeholders will not be able to solve the problem since the cooperation of the citizens as well as the tourists who are visiting South Bank from abroad is crucially important to resolve these issues. Experience of the overall field trip The field trip in South Bank helped me understand the issues that are faced by the residents and the individuals who have visited the destination from abroad as tourists or for business purposes. One of my major learning about the eye catching destination includes engagement of the latent and overt social ways that can be considered as the hindrance in the growth of the sustainable ways South Bank (Brisbane Regional Tourism Investment and Infrastructure Plan, 2018). The place is beautiful but we found that the sustainability is missing due to issues like excessive green house gas emission, high pollution and overly crowded places. Besides learning about the sustainability issues of South Bank, we also learned about various initiatives that are being taken by the government as well as the tourism stakeholders in order to minimize. We understood that resolving the issues are necessary in order to retain the tourists and save the city from the hazardous effects of green house gas. This helped me to understand the impact of carbon emission and overcrowding population on the overall development of a city. The fact that a single issue like carbon emission can give rise to several issues that includes power and water shortage along with air and water pollution was also learned by me. Apart from this, various remedies to overcome water and power supply shortage which includes storm water harvesting and implementation of photovoltaic cells was also learned by us. Finally my experience at South Bank was impactful since apart from enjoying the natural beauty of the city and its beaches and museum, we also gathered knowledge about the shortcomings of the place and the necessary measures to resolve the issues.

The popularity of Credit Derivatives first came into play at the early 1990s The WritePass Journal

The popularity of Credit Derivatives first came into play at the early 1990s Introduction The popularity of Credit Derivatives first came into play at the early 1990s IntroductionCredit Derivative OverviewStructure of Credit DerivativesThe significance of Credit DerivativesCredit Derivatives and the Financial CrisisCredit Derivatives Regulation Conclusion References Related Introduction The popularity of Credit Derivatives first came into play at the early 1990s, when Demchak (Team leader at JP Morgan, responsible for creating CDO’s) and his team have invented these financial instruments (Eisinger 2008). After the failure of the Bretton woods system in 1971, the economy faced a stable state with low interest rates. Banks struggled for profits with a low demand for loans. In these financial circumstances, banks lacked methods that avoid them from bankruptcy, and guarantee that they could survive independently and remain solvent on the collapse of the economy. Credit derivatives were born of such concern, allowing bankers, and others, the ability to reduce their risk by selling risk to other parties (Ayadi, Behr 2009). This paper gives a general overview on the concept of credit derivatives. In its opening section, this paper introduces credit derivatives definition, structure, and its usefulness in the financial market will be introduced. The essay then goes o n to review the existing credit derivatives markets regulation and explains the need to regulate these markets in light of the recent financial crisis. Although credit derivatives may have beneficial effects, but it can only be obtained if credit derivatives are used responsibly by all market participants. This essay will argue that the current regulatory regime is not sufficient to induce market participants to use credit derivatives in a desirable way. Credit Derivative Overview Credit derivatives are financial contracts that effectively shift credit risk, or the default risk, from one party to another. In so doing, for example, Paula Tkac (2007) describes that if participants default on their bond payment, the bond value decreases. The credit derivative, consequently, transfer this credit risk to another market participant for a specific periodic payment. Credit derivatives have achieved a marvelous growth throughout the past decades. According to the British Banker’s Association (BBA), the global outstanding notional volume of credit derivatives was 180 billion USD in 1996. After a decade, the market size of derivatives had increased 112 times the previous size in 1996 with a 20 trillion USD of derivative contracts. Only 2 years later, by mid-year 2008, and as it is shown in the figure 1 below, the fair value of the outstanding amount of credit derivatives was 53.3 trillion USD, reflecting the continuous growth of this market.(Ayadi ,Behr 2009) Structure of Credit Derivatives Credit derivatives can be categorized as portfolio credit derivative (single name) or asset backed security (multiname) (Mengle 2007). The most popular single-name derivative is the credit default swap â€Å"CDS†.   Shah Gilani (2008) illustrates that this is a contract that provides insurance from default risk of a specific party. This party is known as the reference entity and the default risk is identified as a credit event. In a CDS, the buyer of the insurance obtains the right to sell bonds issued by the party for their face value when a default takes place; also, the seller of the insurance agrees to buy the bonds for their face value when the default occurs (Gilani 2008). This face value is known as the CDS notional principal and the periodical payment the buyer of the CDS pays is known as the credit spread (Gilani 2008).   On the other hand, the most popular asset backed derivative is the collateralized debt obligation (CDO). This derivative is created by packaging a pool of similar assets or loans into one single investment that can be traded (Mengle 2007). When a CDO is purchased, the investor ends up with a basket of bonds. This portfolio of bonds generated an income that is used to provide a promised return to tranches. (Mengle 2007) The significance of Credit Derivatives According to David Mengle (2007), credit derivatives came out in response to two traditional problems facing the banking system. First, taking a short position in credit was not possible. Thus, a lender cannot fully insure the safety of the loan from default. Second, diversification of credit risk was difficult to achieve and became a problem in the financial market. Given such problems, the only way to enhance the financial world is by the creation of the credit derivative market. These derivatives helped banks to buy ‘protection’ (insurance) through allowing banks to sell credit and hedge their exposure to credit losses. Moreover, using the single-name derivative CDS do not require any permission from the reference entity (Gilani 2008). Therefore, Mengle   (2007) believes that the second problem can be solved when lenders hedge and reduce their exposure to risky investments, and by that they achieve diversification. Particularly, Ayadi and Behr (2009) researched and found out that the increased use of hedge funds provided an essential source of liquidity in credit derivative markets. This helped banks in reducing their credit risk by allowing them to transfer assets and credit risk off their balance sheets. Also, it improves their liquidity by providing secondary markets for credit risk. (Ayadi, Behr 2009) Credit Derivatives and the Financial Crisis It is often argued that the flip side of credit derivatives played a major role in the collapse of the financial market. First of all, critics of credit derivatives, such as Tim Weithers (2007), claim that risk transformation ballooned systematic risk, given the difficulty of identifying participants holding the credit risk. Some complain that the CDS notional amount accounting requirements worsen the credit crisis for many financial institutions (Partnoy 2009). Yet, supporters, such as David Mengle (2007), counter that if banks had properly valued their risk exposures at the beginning, they would avoid crash when crisis hit. Second, the argument that credit derivatives increase overall risks by transforming credit risk to less experience with less regulation institutions makes an implicit assumption that government regulation automatically leads to more cautious risk-taking (Partnoy 2009). But this argument ignores the potential moral hazard associated with such an assumption. David Mengle (2007) illustrated that where he believed that unregulated institutions are not protected by the government, such institutions are likely to have incentives to manage credit exposures. (Mengle 2007) Nevertheless, in almost twenty years, credit derivatives have expanded from nothing into a $54.6 trillion market. Nicholas Varchaver, senior editor and Katie Benner, writer-reporter (2008) found that this increase is because an investor does not have to own a bond to buy a CDS on it anyone can place a bet on whether a bond will fail. Indeed, they believed that the majority of CDS now consists of bets on other peoples debt. But, and on the contrary, this problem occurred due to the lack of financial regulation. The supporters of the credit derivatives believe and agree with other critics that these risk financial contracts led to a financial collapse (Mengle 2007). However, the unregulated area of the credit derivatives led to misusing these instruments. For example, during President Clinton phase, the Housing and Urban Development (HUD) secretaries started regulating banks to lend to the poor more (Partnoy 2009). They expected Banks to loosen their lending standards. Yet, Banks undertook investment banking. Specifically, Banks started lending to people whose credit history was suspect and who couldn’t afford mortgage payment (Partnoy 2009). Thus, credit derivatives were used in a wrong manner and led to the deterioration of the financial market. Credit Derivatives Regulation There has been high level of concern with respect to what regulatory steps should be taken to use credit derivatives properly. Ayadi and Behr (2009) have demonstrated several methods that help in regulating credit derivatives properly. First, companies and banks should provide higher transparency through additional reporting requirements. Second, systemic risk should be reduced through the creation of central counterparties (CCPs) for standardized contracts. Finally, banks should impose higher capital requirements for at least some of the market. Yet, these regulations do not mean that credit derivatives are safe from improper use. For example, the creation of CCP’s concentrates the risk in a small number of institutions and creates institutions that are too big to fail. Moreover, high transparency has an impact on market quality and in particular on market liquidity. Madhavan (1995) studied the relation between the market and the availability of trading information to market investors. He shows that fragmented markets are highly demanded by some market participants where their trades are unknown. Madhavan (1995) also shows that greater transparency reduces price volatility. Conclusion Credit derivatives are financial instruments used for credit risk management purposes. The structure of these derivatives enhanced the world financial market and provided a safer investment for banks especially. However, these complex derivative contracts have led to the recent economic collapse. The regulation measures included a lot of mistakes and have lead to the fact that financial institutions created such complex CDO’s and sold them without fully understanding them. Also, the availability of unregulated areas helped in misusing credit derivatives. The true purpose of derivatives was for managing risks and not blind speculation. Thus, if simple derivatives such as put, call options, interest swaps and futures are used wisely, they can be used in productive, safe means. In conclusion, the financial market is exposed always to new participants with new mentalities. Therefore, regulating credit derivatives will not avoid financial crisis in the future if there are no strict control on new participants entering the field. References Ayadi, R.

If people are just complex machines, what does that suggest about the Essay

If people are just complex machines, what does that suggest about the moral status of machines Could I be committing murder every time I turn off my computer - Essay Example Every machine has a system that makes it work, which is composed of several electrical and mechanical subsystems. Likewise, human body functions as a result of mutual work of circulatory system, digestive system, and respiratory system etc. On the other hand, like every machine either needs charging or fueling to work, human body needs food for the systems to work. This paper analyzes the moral status of the act of turning a computer off and discusses whether it can be called as a murder or not in light of the perception that humans are just complex machines. While humans may qualify to be called machines keeping these factors in mind, there is a very important factor that humans contain that machines do not; Emotions. Humans have feelings. They can not only think, but also evaluate the pros and cons of different options and select the most suitable option in a given context. Machines do not have this capability. Some machines like computers do have the capability to evaluate the different variables of certain mathematical procedures, but that knowledge is fed into the computer by humans themselves. A computer does not have the capability to feel for something nor does any other machine. On this basis, it is irrational to define humans as complex machines. Hence, on the basis of the argument that humans are much more than complex machines, it is not justified to comment upon the moral status of machines as the laws of machines are different from those of the humans. While a human can be sentenced to death for having committed the murder of another human, a machine cannot be dealt with in the same way since the machine cannot commit murders in the first place. Likewise, turning a computer off is not similar to committing a murder. Concluding, on the basis of the points discussed in this paper, it is wrong to think of the act of turning a computer off

The acid and enzymatic hydrolysis of glycogen Essay

The acid and enzymatic hydrolysis of glycogen - Essay Example Glycogen structure is similar to the amylopectin molecule and it is highly branched. The presence of the monomer compounds are identified by both acid and enzymatic hydrolysis. The acid hydrolysis takes place over a period of time. The acid hydrolysis by the mineral acids takes place readily. The acid hydrolysis product is glucose.(Melville and Alsberg 1930). The enzymatic hydrolysis of the glycogen by the a-amylase (a(1 ®Ã‚  4) glucan, 4-glucanohydrolase, E.C.3.2.1.1) cleaves the alpha 1ïÆ'   4 linkage in the glycogen molecule yielding a mixture of glucose, maltose and dextrin at the end. (Barbour, 1929). The alpha 1ïÆ'   6 hydrolysis does not takes place as the enzyme is specific for the alpha 1ïÆ'   4 cleavage. As the hydrolysis occurs in a random manner, a variety of the products are formed. (Plummer, 2001).In both the hydrolysis procedures the end product differs. The glucose is the only compound in acid hydrolysis whereas in the enzymatic hydrolysis glucose, maltose and dextrin are the products. The end products are reducing sugars hence the estimation of the reducing sugars is carried out by the Dinitro salicylic acid method. The increase in the number of the reducing sugar production as the hydrolysis takes place is determined by the Dinitro salicylic acid method. The reducing sugars have free carbonyl group with them. This free carbonyl group is oxidized by the 3,5-dinitrosalicylic acid (DNS). Simultaneously the DNS is reduced to 3-amino,5-nitrosalicylic acid under alkaline conditions. This is a basic redox reaction. (Miller, 1959). The reducing sugars are easily measured by the 3,5-dinitrosalicylic acid (DNS) method. According to the Lambert Beer’s law, the concentration of the solution is directly proportional to its optical density. So if the absorbing index of a particular solution is known then the concentration of the given solution at that particular wavelength can be determined by measuring the optical
