Phytomining †Pros and Cons Essay

Phytomining describes the production of a metal crop by using high-biomass plants, which are plants that produce energy or a usable resource when burnt. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bio-ore. As a potential alternative to environmentally destructive mining practices, phytomining has great promise to transform the way metals are extracted from the environment; however, phytomining has yet to produce metal yields that would begin to satisfy global demand. Environmental Considerations It is generally accepted that phytomining is greener than conventional mining practices. In environments with metal-contaminated soil, phytominers can recollect metal pollutants from the soil, thereby restoring the soil to health. Still, growingmass amounts of plants also takes a toll on the land used for cultivation. Industrial farming practices deplete the soil and overgrowing biocrops has the potential to permanently alter an area’s ecology. Economic Viability If the scale of production is large enough, phytomining could become a cheaper alternative to excavation, but large-scale harvesting of plants with concentrations of metal is currently more costly than extracting metals from mines. In the future, as metal prices rise and the yields from mines deplete, this could change. The shortage of metal from mines and persistent demand for metal by industry would offset the costs of initiating large-scale phytomining farm production. Growing Conditions Phytomining’s success is subject to the forces of nature. Unlike traditional excavation, phytomining is dependent on growing conditions such as the weather, altitude and soil quality. A bad growing season could wipe out an entire crop of metal-producing plants, and if global climate change alters weather patterns, the risks associated with establishing a long-term phytomining industry in an area increase. Other Considerations As with any new industry, much is unknown about the long-term effects of phytomining. For example, with a limited amount of good farming land available, what land use would be displaced to make room for a phtyomining industry? Researchers will also need to examine the effect of having metal-enhanced plants entering the food chain over time. They will also need to determine if it is possible to prevent metal runoff from the plants from entering the local water supply.

Stylistic analysis: One Stair Up by Campbell Nairne

The book â€Å"One stair up† was written by a Scottish novelist Campbell Nairne in 1934 and describes the life of a working-class family from Edinburgh. And we can see a fragment that shows fine style and good sense of humour. The scene takes place in one of the Broadway cinemas. Two young people – Andrew and Rosa – decided to watch some movie. The culminating point of this story is the moment when Andrew says in excitement, â€Å"Good, isn't it? †, but receives the answer, â€Å"I don't see anything funny in that†. In this scene we can see how different Rosa and Andrew are.From this fragment we don’t know anything about their origin and social status, but we can guess that Rosa was from richer family than Andrew, that’s why she had better taste and didn’t like the foolish comedy. We can also easily understand it from one sentence: â€Å"It pleased her to be seen in the dress circle, even with Andrew†. She hoped to see so me of her friends to spend more pleasant time with them, but as she couldn’t see anybody, she had to stay with Andrew. There is one more evidence for it: â€Å"Is he really so stupid, she wondered. Yes, I suppose he is†.All these facts show us that Andrew and Rosa had very different social status. So, we can say that the main idea of this small fragment is to show how difficult it is for people from different classes to understand each other. What is fun for one is absolutely fool for another. Some habits, like talking in the cinema, are absolutely normal for one and unacceptable for another. I think that the moral of the story can be very well illustrated with two proverbs: â€Å"Tastes differ† and â€Å"A place for everything and everything in its place†. In order to describe the scene properly author uses different stylistic devices.On the whole he describes the movies that the heroes watched in details, so the reader can easily imagine everything that happened on the screen. For this aim the author forms his speech into short sentences that follow one after another like the scenes of the movie. But to make the story more artistic he uses, first of all, different epithets: â€Å"shadowy faces†, â€Å"looped curtain†. Also there are similes: the carpet â€Å"yielded like springing turf†, â€Å"a hard-worked dog, for you saw it, or another like it, in dozens of these comic films† and other to recall some associations in the readers’ mind and to make the images more  Ã¢â‚¬Å"visible†.What is more, similes help the reader understand the way of thinking of different characters and the author, too. The author uses different set phrases like â€Å"The film seemed to have smashed all records. It drew tears from the hardest hearts. It sent thrills down the spine† and others. It is described even with some kind of sarcasm as a sample of bad taste. Also there is an oxymoron: the main part in the â€Å"mightiest drama of Broadway† has a â€Å"bewitching† actress named Minnie Haha.Also the author uses book and high lexicon for usual things, for example: â€Å"to-night he would resist that awful temptation to explain the story in a whisper†, so it’s a burlesque. As for me, I liked this story, but I feel pity to Andrew. It is better to have a good sense of humour than trying to show your tastes. And Andrew just wanted to have better social position and dated with a girl from a rich family. But it is really difficult to them to be together. So, I think that Campbell Nairne had shown everything really truly.

Before You Were Mine by Carol Ann Duffy Essay

â€Å"Before you were mine† is a poem written by a daughter about how she imagines her mother’s life ten years before the daughter was born. The author describes the photo of her mother with two of her friends. They â€Å"shriek at the pavement† and seem to be sharing a joke, young and lightsome (line 4). She knows that the thought of having a child one day doesn’t occur to her mother when she was young and had a lot of dreams. Now remembering her own childhood, Duffy thinks of how she used to play with her mother’s red shoes and imagines when her mother might have worn them. She remembers how her mother used to teach her dance steps when she was a little girl. The poem is a four stanza one, each stanza being made up of five lines, with some variation in length of line. The first two stanzas focus purely on the life of the mother before the daughter was born, whilst the third stanza opens with a reference to the daughter’s birth and then moves to the daughter’s vision of her mother in her earlier life, thus providing a link with the previous stanzas. The fourth stanza begins with a recollection from the daughter’s younger life with her mother, and then takes us back once again to the mother’s days of dancing. I consider that the language contributes to the mood of the poem. The poem is written in first person narrative voice. There are many references to her mother as very happy – â€Å"you laugh / the bold girl winking in Portobello†, â€Å"you sparkle and waltz and laugh†(lines 13-15). The author’s mother’s life can be perceived as flashy. Her mother is likened to Marilyn Monroe: â€Å"Your polka-dot dress blows round your legs. Marilyn† (line 5). Duffy’s mother dreams of â€Å"fizzy, movie tomorrows† (line 7). The poem is written in the present tense, as if the events of the photo are happening now. I suppose in this way the poet tries to make her mother’s past as real as possible. It seems juicy to read a poem in which a daughter imagines how full of life and fun her mother must have been before she was born. Her admiration of her mother is shown in a direct way, and words such as â€Å"shriek†, â€Å"sparkle† and â€Å"fizzy† image the carelessness of youth. Throughout, the poet is very possessive of her mother. References to her appear constantly: â€Å"I’m ten years away†¦ †, â€Å"I’m not here yet†¦ †, â€Å"I remember†¦ † (lines 1, 6 and 12). The word â€Å"mine† appears in the title and the poem actually concludes with the same words as the title, as if the poet is locking her mother in a firm embrace of words.

Questionarise for survey of customer buying performance for Essay

Questionarise for survey of customer buying performance for technological goods - Essay Example 152). Therefore, this study aims at indentifying buying preferences of customers towards sustainable technological goods which in this case will be different brands of cars. Moreover, the study aims at exploring technological elements that make some brands of cars to be highly purchased as opposed to others. Sample size of 1764 was used for the study. The result indicated that consumers purchase technological goods based on the quality, safety, value, performance, design, innovation, and environmental friendliness/green factors. Introduction Numerous factors usually affect the purchase decision of the consumer and most of these factors have been used in understanding market for specific goods and or services. Nonetheless, satisfaction of the consumer is usually pegged on the consumer’s cognitive and effective evaluation of the past experience on certain purchases. Additionally, the consumer’s purchase decision may be analyzed based on perceived risks. Therefore, underst anding these elements are quite beneficial to the new or technological good manufacturers especially those who intend to introduce new goods into the market (Mohr, Sengupta, and Slater, 2010; pg. 101). However, purchasing new technological goods will require more than the risk perception on the good, but will also require limited theoretical assessment of the entire purchase process that is defined within six risk dimension that include the assessments of the performance risk, financial risk, physical risk, convenience risk, social risk, and psychological risk (Pride and Ferrell, 2012; pg. 144). Each of these dimension of purchase risks usually have different significance on product or purchase risk or context; therefore, they must be considered independently by the consumer in determining their purchase decisions (Shaw, 2003; pg. 62). Therefore, these aspects or purchase risks will be considered independently in analyzing the factors influencing the purchase decisions of consumers to purchase technological cars. Literature Review The choice of customer is usually governed by the microeconomic theory that connects the preferences to consume goods and services in relation to the consumption expenditure. Therefore, choice of the customer usually affects the consumer demand curves. The relationship or the link between consumption, personal preferences, and demand curves is usually considered business economics since it helps in analyzing how the customer often achieves the equilibrium between expenditure and preferences (Crane and Mayer, 2003; pg. 179). This analysis is usually done by considering how the consumer maximizes utility as subject of budget constraints. Preference often presents the desire of an individual to consume a good and service thereby translating to consumer choices. Notably, these choices are usually based on wealth or personal income combined with the available time the consumer has to define consumption activities. Thus, it is worth noting that consumption is distinctive of production since there are two different actors that are involved. In other words, consumption is the primary aspect of production. A manufacturer may produce a good that would never be consumed; therefore, different abilities

HND Business Law - Essay Example ement is entered into, regardless of the manner in which it is executed, all parties agree to abide by the terms and conditions spelled out in said agreement. Only if all parties agree to be released from a particular clause in the contract, or an agreement is reached to null and void the entire contract, it remains in force. If violated, one party will likely have a claim against the other in a court of law. This brief section covers all three of these different types of contracts. When considering verbal agreements and contracts, it is important to remember that they are legally binding as a written contract in many situations. The key today, however, is proving the terms and conditions in question when a disagreement arises in a modern business situation. Under UK law, it has been largely determined that there are two main areas that constitute an actual binding agreement between two or more parties. The first involves whether or not an agreement was actually clearly reached as to the services that were to be performed, or goods provided. The second involves remuneration. If a figure was reached and agreed upon, it would be considered binding. Interestingly enough a verbal agreement today can be reached via either an in-person or on telephone voice exchange, or via email. Verbal contracts are more difficult to prove in a court of law. If one party states that the other party did not meet the conditions or warranties stipulated in the agreement, then problems can arise. If these are written out in a formal and written agreement, the issue is often quickly resolved. If, however, the agreement was verbal in nature, it can quickly become a ‘he said, she said’ affair that makes it difficult to prove one way or other in court. As such, it is recommended that the terms and conditions be clearly spelled out in a contract. Written agreements, quite simply, are similar to verbal agreements, except that they have a verifiable signature on them from all

Infectious disease - Research Paper Example Dr. Kai Kliiman has also been an efficient manager for the National Tuberculosis Program. The authors have a biased interest as they tend to incline their article to their point of view. Though there is also some vested interest which is obvious through the biased interest, the article does not tend to show any prejudices. Since the article talks about established facts and has less to do with assumptions, this article shows the biased interest of the authors than the vested interest. This is a peer reviewed article and this can be confirmed by the article itself. The article does attribute the critical revision, provision on study materials, collection and assembly of data and other important aspects of the article just to both the authors and no other source of cross check involved and hence it is obvious that this is a peer reviewed article. The article â€Å"Predictors of extensively drug-resistant pulmonary tuberculosis† is about the study conducted on several patients in Estonia suffering from culture confirmed pulmonary-tuberculosis. The article educates the readers about the brief study conducted on patients with extensively drug-resistant tuberculosis and multi drug but non-extensively drug resistant tuberculosis and the efforts to identify the their causes. ... s and continents in which it is prevailing and is spreading, and also speaks about the number of deaths that are reported every year owing to this infectious disease. The article speaks much about the studies conducted on patients of Estonia, which had the highest number of cases of multi-drug resistant tuberculosis. Initially the reader gets exposed to the details of the spread of the disease in spite of the measures that had been taken and also the effect of NTP (National Tuberculosis Control Program). This in association of HIV virus is spoken about and their combined effect is also talked about. â€Å"In certain African countries and many parts of Southeast Asia, HIV is becoming more and more endemic. Where tuberculosis is also endemic among the population, a weakened immune system will increase the risk of getting tuberculosis. This is an extremely worrying situation and the WHO and the IUATLD are doing all they can to prevent the disease from spreading† (Dr.Pallisgaard, 21). The adoption of several sophisticated methods for this study is also mentioned in the article. The study has taken into consideration factors like sex, age, place of birth, economic status and other factors like drinking habits, marital status and employment and studied their effects too. These tests were conducted dividing the patients into three separate groups, namely the extensively drug resistance tuberculosis, multi drug but non-extensively drug resistant tuberculosis and non- multi drug but non-extensively drug resistant tuberculosis. All the data pertaining to the patients has been collected and stored in a database. Tests have been conducted in highly equipped labs and highly qualified people as per the directions of WHO. In each case susceptibility has been gauged separately and

Abdurrahman Zeitoun and The Hero with a Thousand Faces Essay

Abdurrahman Zeitoun and The Hero with a Thousand Faces - Essay Example The object of this paper is to depict the journey of a real life hero seen through Campbell’s version of heroic adventure and dilemma. Campbell has put forward three main criteria as features of a Hero’s journey. The actions and adventures of a real life personality, Abdulrahman Zeitoun are assessed on the basis of the criteria mentioned by Campbell. The altruistic deeds of Zeitoun has placed him on the altar of a modern day Hero and can be a guiding light for the young generation to be strong and fearless in all difficult situations. The mythological set up of Joseph Campbell’s book The Hero with a Thousand Faces has expressed the adventures of an emerging Hero. With many mythological examples the book explains how different people can display courage in the face of adversities and achieve the status of a Hero by fulfilling the call of their missions. The journey of the Hero starts when he gets a call for a mission and on basis of the call he steps in a hitherto unknown and supernatural world from the comforts of his ordinary world. In this journey he faces many hurdles which he overcomes with great display of courage and determination. Eventually, he returns to his homeland equipped with all the powers of a superhero and from then on he uses his power for the welfare of his people. There are three different stages of the journey to heroism and they are Departure, Initiation and Return. The journey that one has to make in his life indicates moving forward without any hesitation and. The journey is full of challenges that one has to overtake with sheer integrity and willpower. Only by overcoming the fear of the unknown, one can emerge victorious as a true hero. The mythological journey of the Hero depicted in this book can act as an inspiration for generations to come. (Campbell, xxiv) Campbell depicts in his book the three stages through the story of a mythological character’s journey and his adventures. He uses various appropriate examples from mythology and religious history to describe the journey of his hero. He embarks on the journey when he gets a call from the supernatural and the first stage of the journey begins when he faces Separation from his own ordinary world. (Campbell, 45-53) â€Å"A sharpened edge of a razor, hard to traverse, A difficult path is this—poets declare!† – (Campbell, 21) Every man who dares to respond to the call of the unknown knows very well the dangers lurking ahead and he alone has to face them with courage and determination. (Campbell, 21). Initially he refuses to respond to the call but then he is assured of supernatural assistance. This gives him the courage to embark on his journey and face the challenges ahead. The second stage is about the hero’s Initiation to the supernatural world. In his journey to this mystic world he faces many tough challenges and tribulations but every time he overtook them and achieved victory with his extraordinary po wers. His bravery won him the good fortune of meeting the Goddess. â€Å"At their word, the word which tortures the spirit, The sick woman was turned into a corpse, The corpse was hung from a stake† – (Campbell, 99) The hero of every era at one time or the other in his life has to confront his other self either by being absorbed by it or by absorbing it. Life will throw at him challenges which will require him to let go of his pride and inhibitions and he must surrender himself to the flow to rediscover himself. In this journey the Hero was provoked towards temptations and like any ordinary man he surrendered his will power to such provocations. Still, the Holy Father gave him the chance to atone for his weakness and thus he received the chance to cleanse himself of his sins. Gradually he gets elevated to divine status and he is bestowed with powers
