Research Paper on Sewage Treatment Essay Example

Research Paper on Sewage Treatment Essay Sewage treatment is a set of techniques that include water purification to recycle wastewater into the environment, or to convert it into drinking water. In terms of foresight and the Rifkin’s dynamic, as well as under the conception of â€Å"smart and sustainable city† (including automation), there is a tendency to provide, similarly to the Smart Grid, which builds â€Å"smart† energy networks, technical solutions to make water systems more â€Å"intelligent† and efficient (the conception known as Smart Water). A common field between these two approaches could be in the sewage drains heat recovery or the use of water network as a global cooling system. There are two main techniques to purify water, applying to both wastewater treatment and the production of drinking water. The physico-chemical techniques are essentially reserved for the drinking water production. The use of chlorine dioxide, sodium, and ozonation is also effective. In recent years, it took many efforts of the research and development departments to cope with the increasing complexity of pollution, regardless of its source. New fertilizers placed on the market, the identification of new sources of industrial pollution, as well as pharmaceutical (residues of active drugs rejected by individuals) actually pose new technological challenges to the treatment.

In its basic configuration, they are mainly used for the removal of carbon compounds present in soluble form, such as sugars, fats, proteins, etc., for which solutions physico-chemical means are often inefficient, costly, or difficult to implement. These are harmful to the environment since their degradation involves the consumption of dissolved oxygen in water necessary for the survival of aquatic animals. The purpose of biological treatment is to remove the soluble organic pollution by microorganisms, mainly bacteria. The heterotrophic microorganisms that use organic matter as a source of carbon and energy, have a dual action: The organic material is partially removed in gaseous form during carbon mineralization with CO2 production in aerobic processes and biogas (CH4 + CO2) in anaerobic processes, and partly transformed into solid particles consisting of micro-organisms resulting from bacterial growth. These particles can be easily separated from the liquid phase by physico-chemical means such as settling for example. If necessary, the transformation of ammonium ions (NH4 +) to nitrate (NO3-) or nitrification, which may be performed simultaneously. These methods can also remove nitrogen and phosphorus by biological method through the implementation of additional steps in the treatment process: setting up an anoxic tank, an anaerobic pond, etc. Sewage treatment is a very urgent topic these days, so it is very important to put all your efforts in order to create a good research proposal on the subject.

The most important thing to most Americans today is the type and quality of relationships that they have with other people. Everyone is trying to have the abundance of friends that has been adopted to be the major driving force in society. Over time, people have begun to pursue relationships with friends and acquaintances rather than with their own family. It is in the family that the true values and lessons of life are learned. Ones family is the most important thing that anyone has. People have long forgotten that relationships within the family are of far greater importance than relationships outside the family. Young people today have stopped valuing a good, close, inner family relationship. One of the biggest secrets in life that many do not know is that much of our inner wellness and satisfaction comes from the family. Does that sound odd? If, beginning at any early age, a child receives much love and experiences much happiness within a family, wouldnt he be happy outside of the family as well? Many teenagers today complain about how intolerable their families can be. When something is wrong within the family, it is usually seen expressed outside the family. Teenagers seek refuge with their friends and desire independence from parental control. The one thing that every person wants is to be accepted and loved by someone. Moreover, if they do not feel like they are getting it from family members, then they will seek out other means. As a result, teenagers and young adults feel that it would be a waste to spend time with their family. The family is a refuge and a learning center. A family should be where anyone can go back to in times of need or trouble. When things are not going right, a family is something everyone can always turn to.

HMV Group Case Study Example | Topics and Well Written Essays - 3500 words

HMV Group - Case Study Example This report highlights the various strategic options available to the HMV Group as well as an analysis of the potential effectiveness of these new strategies based on the current strategic position of the organisation. an isolated incident which did not stem from higher consumer patronage and online sales, but from the sale of HMV Japan (Bryant, 2008). It appears that HMV Group was experiencing minimal sales volumes in the Japanese division of the company, thus the sale of this particular business unit was performed in order to increase total company liquidity and make the company's stock appear more viable for long-term investment. The implementation of the Japanese HMV division did not bring adequate sales results to the company, thus this was an initial failure at diversifying the company's total business portfolio. Additionally, and much to the surprise of the HMV Group leadership, the company experienced its best Christmas sales in December 2008, largely due to video game sales in the HMV division (Financial Times, 2008). This seems to have taken the company on a new strategic direction by January 2009, with a much higher focus on video game sales and less focus on music sales and downloads. The 3.0 Strategic options for HMV Group The company is currently facing a considerable amount of competition stemming from the rise of online retailers, the digital download environment competitors and also supermarkets which appear to be attempting to cash in on music and other digital media sales (Bryant). There is no research evidence which suggests why consumers are moving toward supermarkets and online retailers for their music and digital media selections, however since these competitors are eroding the firm's total profitability, the company needs to select several new strategies in order to build competitive advantage and emerge, again, as the leader in this type of digital format sales. Pricing Strategy: From a sales and marketing perspective, the company would benefit from taking both a price-based strategy and a differentiation strategy in order to build the type of sales growth expected by the company. In today's difficult economic environment, it is relatively common knowledge that many consumers have cut back on their spending habits due to fear of the short-term effect on personal consumer income. The company should adopt a low price strategy and a

Bollinger Bands and RSI Essay Example | Topics and Well Written Essays - 1250 words

Bollinger Bands and RSI - Essay Example As the report stresses the purpose of an RSI is to compare the magnitude of recent gains to recent losses in an attempt to determine overbought and oversold conditions of an asset. The RSI is best used as a valuable complement to other indices, for in and of itself it is susceptible to the fact that large surges and drops in the price of an asset will affect the RSI by creating false buy or sell signals. Different RSI settings can allow traders to get more accurate market readings about different strategies that they might wish to use. â€Å"Swing traders† might want to set the measured period at 15 days, while those buying to hold for longer times might want to make it equal to 30 or even 50 days. In this analysis the author has made the Bollinger Bands our trade trigger and the RSI our trading confirmation. The two indices must be simultaneously within their respective domains where we desire them for a given buy or sell position, or we ignore the trade signal and hold everything. He has used this strategy so that the â€Å"noise† created by volatility indicated by the Bollinger Bands gets reduced by the â€Å"high pass filter† of the RSI reading. Simply put, he is looking at once at an individual stock’s performance and at that stock’s industry’s performance. The author has taken an aggressive approach in our analysis. This was a result simply of following the strategy that we had laid out; we were not attempting to be overly aggressive nor overly conservative and we were not tossed to and fro by emotions.

The 3-year beta is 1. 7, which means that it bears more risk than investing directly in the Samp;P 500, however this also means that it could provide heftier returns. The mutual fund portfolio’s composition

Philosophy as Metaphysics :: Philosophical Papers

Philosophy as Metaphysics (1) ABSTRACT: Philosophy works with special types of objects: the totalities. The basic characteristics of this type of object are their metaphysical, transcendental, and total character. The character of these objects determines the specificity of language and the methods of philosophy. The language of philosophy represents symbolic language; speculation is the basic method of philosophy. On the one hand, objects of this type emphasis homo sapien as essences capable of constructing such objects, which in turn assumes the ability of human consciousness to make synthetic acts. On the basis of philosophy as metaphysics, an original approach is offered which divides the history of philosophy into periods as well as providing analysis of different philosophical systems. Feature of philosophical activity, as against a science, is the work with special, not physical objects — the totalities, which are constituted by the philosopher. One of such objects is the world, and, in this sense, we often say, that philosophy is a wel-tanschauung (world-outlook) . Certainly, the world as some set of things can be studied by physics (sciences in a broad sense), but in this case a researcher can miss the point that the world is a totality, not just a simple set of things. As distinct from scientific study the philosophy takes its objects as the totalities, which the subject of knowledge cannot study as ordinary objects, because the including the learning subject character of these the totalities excludes any standard scientific approach to knowledge in principle. Others examples of the above mentioned objects (the totalities) are Ego and God. Objects of this type (with some reservations) are a lot of human being phenomena, such as love, virtue, conscience, courage, bravery, understanding and so on. All these objects are those, that the precise fixing of objective criteria of their existence is impossible, it is impossible to create the high-grade theory of these phenomena (for example, theory of love or bravery), as they assume not only objective Contemplator (as it occurs in case of objects of scientific knowledge), but also postulate the Actor inside them, that causes essentially twinkling way of them being.(2) Exactly the character of these objects determined essential features of the philosophizing as metaphysical activity. The underlining of metaphysical character of philosophy objects dictates the special procedures of work with them, distinct from of methods of scientific knowledge. Metaphysical objects — constructs cannot be given in frameworks of physical experience; the study — constructing of these objects occurs by a way of thinking means, procedures of speculation.

Ambugity and Clarity in Writing

I chose example 2 which stated â€Å"I was thrown from my truck as it left the road. I was later found in a ditch by a flock of wild turkeys. † This statement in my opinion is an example of vagueness. The vagueness comes from the statement that is very unclear. I am having a hard time understanding how this person was thrown from their truck. It is missing information and is hard to follow. This statement allows me to know that the person was thrown from a truck but we do not know how or how they were found by a ditch of flock.This could have been by a car accident or by someone who could have literally threw this person out of the truck. This type of vagueness throws the reader off because they are unclear of what is really going on in the writing, it becomes a problem when you are trying to understand reasoning behind this statement. The second sample writing I chose was â€Å"The online course helps me in a lot of ways. I can use all kinds of resources. The place in the li brary offer tutorials in all different areas, Microsoft Word, Excel and other tutorials.Also, there is services, that offers technical support, tutoring, library help, and then there are financial aid and academic advising. The library section offers help in finding books, journal articles and more. There is even places in math, writing and technical. † This statement is ambiguous because it is open to more than one interpretation. This can be speaking on behalf one online course or the school of online courses. Also when they mentioned that the library offers all types of resources it does not specify which library and where this library can be found. It could be found online or it could be a place where you have to go.When you write a statement it needs to be clearly understood and it should not have your reader trying to understand the statement you are trying to put across. In this example the writer would get that the writer likes online courses but in the supporting sent ences it just goes into stating help from the library and is somewhat confusing. The relationship between critical thinking and clear writing is that they both work together. You have to critically think to clear write. When you are jotting things down your brain is working to come up with these unique thoughts which is critically thinking. They go hand in hand.
