Does this taste right to you? As a Ministry of Environment environmental technician, you are sent to take water for testing. Two of the test sites experienced fish kills and a third, without a fish kill, was used as a comparison site. In an attempt to explain why the fish died at these sites, the water was analyzed for the following chemicals: Site pH NO3 1- PO4 3- Dissolved 02 Suspended solids 8.0 0.2 ppm 0.2 ppm8.0 ppm 4.3 0.2 ppm 0.2 ppm7.0 ppm 6.0 5.0 ppm 6.0 ppm 3.0 ppm Hi Medium Access the long description of the table. Location of sample sites: river metal atripping plant large pig farm kill Fish k Your job is to provide an analysis of the test results to come up with a hypothesis for the experienced fish kills. Site A did not experience any fish kills and is used as a reference site Solution 1. In the site B , the environment is highly acidic as compared to the suitable mild alkaline condition (Site A , pH: 8 ) due to wastages coming from the metal stripping plant. Moreover, the high amount of suspended solids make this environment hazardous for aquatic fauna. 2. In the site C, the most predominant problem is the scarcity of dissolved Oxygen in water due to the presence of high amount of organic wastes coming from the pig farm. Moreover, the presence of excess Nitrate and Phosphate in the environment makes the environment unsafe for fishes. .

Road, Kolkata, India *Address for Correspondence: Atanu Roy, Research Scholar, Department of Biotechnology, Techno India University, Salt lake Campus, Kolkata, India ABSTRACT- Three decades data (1984 – 2015) was used to study the effect of surface water temperature, pH, dissolved oxygen, nitrate, phosphate and silicate on chlorophyll a concentration in three water bodies meant for fish culture (locally known as Bheries) in East Kolkata Wetlands. The data revealed significant spatio-temporal variations (p < 0.01). The increasing trend of temperature, nitrate and phosphate reflects the effect of intense urbanization at local level. The pronounced variation of dissolved oxygen and chlorophyll a (decreasing trend) may be attributed to increased load of sewage in the selected water bodies, which has posed an adverse impact on the phytoplankton standing stock as revealed through decreasing chlorophyll a trend.

Avaragere Lake in Davangere was studied for chemical and physical parameters at five locations, for a period of six months (April 2014 to Sep 2014). Lake has been subjected to human interferences regularly and water quality was to be getting deteriorated profoundly. Major anthropogenic activities practiced in and around the stretch: agriculture, discharging of sewage waste etc was generating serious threat to the biota of the lake by altering the physical, chemical and biological concentration of the lake system. The other possibility is that since there are no major industries in the project area, the major source of organic pollutants is only the domestic source. Monthly data’s been collected. Different parameters studied were pH, Conductivity, organic carbon, nitrogen, phosphorus, potassium, zinc, copper, iron, organothiophosphate and pyrethroid content. The results obtained from the above study indicate that the water of Avaragere Lake organothiophosphate and pyrethroid content shows very low concentrations even at nanogram. Manganese and iron concentrations of sediment sample in avaragere lake shows high level of pollution and ecological balance of Lake is totally disturbed.

advantages and disadvantages of using centralized network management versus distributed network management explain Solution centralized network management : 1) Advantage: i) Centralized management is simpler to develop and maintain. ii) Single location to view events and alerts. iii) Single place to access network management applications and information. iv) Security is easier to maintain. 2) Disadvantages: i) It requires a huge amounts of information to travel back to a centralized network operations center (NOC). ii) Single is system is not redundant or fault tolerant. iii) As networks elements are added, may be difficult or expensive to scale system to handle load. iii) Having to query all devices from a single location. Distributed network management: 1) Advantages: i) Distribution of network management task. ii) Distribution of network monitoring throughout the network. iii) Not dependent on single system. 2) Disadvantages: i) Information gathering is more difficult and time consuming. ii) The list of managed devices managed by each client needs to be predetermined and manually configured. .

Advantages & Disadvantages of Server Applications in 150+ words Solution Advantages: 1. Updates: Updates and patches can be pushed easily on all client machine. 2. Centralized Control and Configuration: Any changes made to the system are centralized like db error or system settings. 3. Better than installing copy on every client machine. Integrity, resources and access of the data are controlled by dedicated servers. It makes difficult for an unauthorized program or person to damage the system. 4. Scalibility: We can manage and control number of clients and severs separately. 5. Back up and Recovery: As all the data is stored at one place on sever its easy to back up and recove data. 6. Accessibility: We can access the server from various platfroms. 7. Security: Servers have better control access and resources to ensure that only authorized clients can access or manipulate data and server-updates are administered effectively. 8. Performance: clients server model improves the performance of large applications in heavy usage environments by restricting the network traffic to performance tier traffic. 9. Easy maintenance: distribute the roles and responsibilities to several standalone computers, you can replace, repair, upgrade, or even move a server, while customers will not be affected by that change (or minimally affect). This independence of the changes is also known as encapsulation. Disadvantages: 1. Server Overloading: When there are a lot of simultaneous client request than server get severely overloaded. Traffic becomes congested. 2. We may need increased bandwidth for the reasom mentioned above so that our server can handle more number of requests simultaneously. .

Do you think Facebook should operate in China even if it means complying with the restrictions there? Solution Yes, Facebook can be allowed to operate in China, by complying with the restrictions that have been suggested by the government. Facebook is a social medium that has its presence all over the world. But a few countries have still posed a ban on the website since it has lead to occurances of cyber crimes and social crimes. The best part is that it is not the only cause. China being a most populous country, it will not be able to spend a lot of work force on solving the cyber crimes or social crimes that might arise out of the intervention of social media. Hence they have a stringent policy of allowing these websites as to put it simple, it will add on the existing problems of the society. The country also feels that it will divert the attention of the student community towards socializing, Asian countries are rich for their cultural values and ethical behaviours which they have a fear of loosing if they allow the social media to venture into their country. So it is always better to stick to the local government and comply the restrictions is order to atleast venture first, and conquer later. .

Do you think contingent gains should be disclosed in the financial statements? Defend your position. Solution Contingent gain or loss is a concept where the firm will suffer loss or will make gain only on hapening of certain contingency or event in future. Suppose a company has claimed some money for extra work. Disput arises regarding the inclution of those work in the contract escalation clause. The dispute has been referred to court. The company will gain, if the judgement of court goes in their favor. It is a contingent gain which will materialize only when judgement is favorable. It is not justified to include them in the financial statement as the gain has not been made. Also it is not certain whether such gain will at all be achieved or not. From convertesim point of view any income or gain which is not sure to be earned should not be included. However it is the responsibility of company to disclose all facts in its report.So that it can project true and fair view of state of affairs of the concern. Hence there should be disclosure in the financial statement in detail about the contingent happenings. .

Do you believe the “double taxation” of earnings which occurs at the corporate ownership structure is justified? Solution Double taxation affects C corporations. Double taxation refers to situations when business profits are taxed at both the corporate and personal levels. First profits are taxed at corporate level before paying any amount to shareholders at the rate applicable to corporate. Then dividends are subject to tax at individuals tax rate Double taxation forces corporations to use debt financing, and encourage them to do retained earnings rather than distriubuting to shareholders in the form of dividends. Since the corporations are put at a disadvantage due to double taxation. This is not justified at all since shareholders are considered owners and their income is taxed twice. Dividend should be made exempt and corporates should not have top pay tax on dividends. thus we can say that double taxation affects business and investment decisions which is not justified at all. .
