Enviromental science - Essay Example Over-population is one of the majors for most of the problems being faced in the world. Population increases with 1.5 people per second around the world, therefore in an hour it increases at the rate of. If we go on to ignoring these statistics and the problems they are creating it is only increasing the human suffering. We human beings are capable of doing many things and so we have accumulated the data of every person who ever lived on earth and it is safely kept in the US. The UN not only preserves the data but it also helps predict the future and these predictions are astounding. It is possible that the total population will increase with the 3.1 billion people till the middle of this century making it 9 billion; we have 6.8 billion people today and it is expected to increase up to 7 billion within the coming 4-5 years this is the most startling fact mentioned in the movie. It means that in 50 years the earth will need to accommodate up to 3 billion more people. Within the next 50 years the people will suffer no matter where they are or how they live. When there is abundance of food, water and right availability of material for shelter, the population thrives and succeeds. But when there is scarcity of the most basic necessities, the world comes under depression. Humans and resources have a very close relationship; the food production cannot increase as fast as the human reproduction can. Therefore, the demand will gradually exceed the supply; if the human population is not controlled at once the life would end miserably. The green revolution was not harmful in fact it was more effective in producing food in abundance through modern farming methods. It helped many countries become self-sufficient in food and alleviate hunger in the world. Out of 70% of water present in the world only 1 % is being provided to the people living in it and the rest is

Product Life Cycle Essay Example for Free

Product Life Cycle Essay Definition: Products come and go. A company’s challenge is to hold on to its customers longer than it holds on to its products. It needs to watch the market life cycle and the customer life cycle more than the product life cycle. Someone at Ford realized this: â€Å"If we’re not customer driven, our cars won’t be either.† One selects marketing tools that are appropriate to the stage of the product’s life cycle. For example, advertising and publicity will produce the biggest payoff in the introduction stage of a product; their job is to build consumer awareness and interest. Sales promotions and personal selling grow more important during a product’s maturity stage. Personal selling can strengthen customers’ comprehension of your product’s advantages and their conviction that the offering is worthwhile. Product Development and Life-Cycle Strategies: In the face of changing customer needs, technologies and competition, product innovation or the development of new products has become vital to a companys survival. Introducing new products, however, is not sufficient. The firm must also know how to manage the new product as it goes through its life cycle: that is, from its birth, through growth and maturity, to eventual demise as newer products come along that better serve consumer needs. This product life cycle presents two principal challenges. First, because all products eventually decline, the firm must find new products to replace ageing ones (the problem of new-product development). Second, the firm must understand how its products age and adapt its marketing strategies as products pass through life-cycle stages (the problem of product life-cycle, strategies). We therefore look initially at the problem of finding and developing new products, and then at the challenge of managing them successfully over their life cycles. Innovation and New-Product Development: Given the rapid changes in taste, technology and competition, a company cannot rely solely on its existing products to sustain growth or to maintain  profitability. The firm can hope to maintain market and profit performance only by continuous product innovation. Product innovation encompasses a variety of product development activities product improvement, development of entirely new ones, and extensions that increase the range or number of lines of product the firm can offer. Product innovations are not to be confused with inventions. The latter are a new technology or product which may or may not deliver benefits to customers. An innovation is defined as an idea, product or piece of technology that has been developed and marketed to customers who perceive it as novel or new. We may call it a process of identifying, creating and delivering new-product values or benefits that were not offered before in the marketplace. In this chapter we look specifically at new products as opposed to value creation through marketing actions (such as product/brand repositioning, segmentation of current markets). We also need to distinguish between obtaining new products through acquisition by buying a whole company, a patent or a licence to produce someone elses product and through new-product development in the companys own research and development department. As the costs of developing and introducing major new products have climbed, many large companies have decided to acquire existing brands rather than to create new ones. Other firms have saved money by copying competitors brands or by reviving old brands. These routes can contribute to a firms growth and have both advantages and limitations. In this chapter, we are mainly concerned with how businesses create and market new products. By new products we mean original products, product improvements, pnxhict modifications and new brands that the firm develops through its own research and development efforts. Risks and Returns Jri Innovation Innovation can be very risky for a number of reasons: 1. New-product development is an expensive affair it cost Tate Lyle around  £150 million to develop a new sugar substitute; pharmaceutical firms spend an average of . £100-50 million to develop a new drug; while developing a super-jumbo project could cost billions. 2. New-product development takes time. Although companies can dramatically shorten their development time, in many industries, such as  Pharmaceuticals, biotechnology, aerospace and food, new-product development cycles can be as long as 10-15 years. The uncertainty and unpredictability of market environments further raise the risks of commercialization. Roots had to withdraw Manoplex, a heart drug, less than a year after its launch in the United Kingdom, after a trial on 3,000 patients in the United States and Scandinavia suggested an adverse effect on patient survival. The pharmaeeudeals division lost about  £200 million on the drug, which cost nearly  £100 million to develop over a period of 12 years, and about S20 million was spent on promoting and marketing it. 3. Unexpected delays in development are also a problem. History is littered with grand pioneering engineering projects which have failed to satisfy the original expectations of bankers, investors and politicians. The Seikan rail tunnel, connecting the island of Hokkaido to mainland Japan, was completed 14 years late and billions of pounds over budget; the S10 billion cost of the Channel tunnel, which opened on 6 May ] 994, a year later than originally planned, is more than double the  £4,8 billion forecast in 1987. 4. The new-product success record is not encouraging either. New products continue to fail at a disturbing rate. One recent study estimated that new consumer packaged goods (consisting mostly of line extensions) fail at a rate of 80 per cent. The same high failure rate appears to afflict new financial products and services, such as credit cards, insurance plans and brokerage services. Another study found that about 33 per cent of new industrial products fail at launch. Despite the risks, firms that learn to innovate well become less vulnerable to attacks by new entrants which discover new ways of delivering added values, benefits and solutions to customers problems.

Gertrude and Helen: Wantonness in the Trojan War and Shakespeares Hamlet :: Shakespeare Hamlet

Gertrude and Helen: Wantonness in the Trojan War and Hamlet      Ã‚  Ã‚   Hamlet is the melancholy Dane; Claudius, the smiling villain. Polonius is the oily courtier; Horatio, the loyal friend. Most of the characters in Hamlet are well defined and unambiguous; the character of Gertrude, however, presents us with many ambiguities and difficulties. Some critics see her as "well-meaning but shallow and feminine, in the pejorative sense of the word: incapable of any sustained rational process, superficial and flighty" (Heilbrun 10), while others see her as a stronger character, cool and calculating. The play presents many aspects of Gertrude's character ambiguously. Janet Adelman writes,    Given her centrality in the play, it is striking how little we know about Gertrude; even the extent of her involvement in the murder of her first husband is left unclear....The ghost accuses her at least indirectly of adultery and incest...but he never accuses her of nor exonerates her from the murder. For the ghost, as for Hamlet, her chief crime is her uncontrolled sexuality; that is the object of their moral revulsion, a revulsion as intense as anything directed toward the murderer Claudius. But the Gertrude we see is not quite the Gertrude they see. And when we see her in herself, apart from their characterizations of her, we tend to see a woman more muddled than actively wicked; even her famous sensuality is less apparent than her conflicted solicitude both for her new husband and for her son....Even her death is not quite her own to define. Is it a suicide designed to keep Hamlet from danger by dying in his place?...Muddled, fallible, fully human, she seems ultimately to make t he choice that Hamlet would have her make. But even here she does not speak clearly; her character remains relatively closed to us (Adelman 15-16).    In spite of the many ambiguities of Gertrude's character, one of her chief characteristics is wantonness, and like Helen of Troy, Gertrude's wantonness led to tragedy. Wantonness-a word that is little in use nowadays-suggests three characteristics: luxuriously rank extravagance, lack of discipline, and lustfulness. The treatment of Gertrude's character in Hamlet supports the argument that her chief fault is wantonness, for these three characteristics can be seen in her character.    The first characteristic, luxuriousness or extravagance, is not directly stated in the play but can be inferred from the actions of Gertrude. One possible reason for her remarriage after King Hamlet's death is a desire to maintain her position as queen, with all its luxury and comfort.

Cari’s Story Essay

A)How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? The infection in Cari’s nasal passages and pharynx was able to spread into her sinuses due to the sinuses being a drainage area for the nasal passages. B)What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. There are cilia in her trachea that is moving mucus up from the lungs. When the mucus becomes abundant it triggers the cough reflex. C)Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? There are macrophages found in the terminal bronchioles and alveoli that normally would protect Cari’s lungs from infectious pathogens and particulate matter. D)How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lungs? The excess mucus and fluid in the lungs would raise the resistance of Cari’s airways because of the small diameter the buildup would cause. The fluid would have some of alveoli under water where they could not function properly and there would also be more friction from the buildup. E)How would Cari’s lung compliance be altered as her alveoli fill with fluid due to pneumonia? Cari’s lung compliance would increase from trying to force gases into and out of the alveoli. Those are filled with fluid due to the pneumonia. F)How would fluid in Cari’s lungs affect her total lung capacity? The fluid in Cari’s lungs would lower her total lung capacity by not allowing the space that is taken up by the fluid to be filled with air. G)How does the elevation of Cari’s respiratory rate alter her minute ventilation? The elevation in her respiratory rate would alter her minute ventilation by raising it. Minute ventilation is determined by times ing respiratory rate by total volume. H)Normal blood oxygen saturation levels are greater than 94 percent; Cari’s blood oxygen saturation level was 90 percent at the time of her exam and an initial arterial blood gas analysis done when she was admitted to the hospital revealed her arterial Po2 was 54 mmHg. How do these clinical findings relate to the internal respiration in Cari’s body? The clinical finding of 90% oxygen saturation level and a Po2 of mmHg would show that the arteries are having too much oxygen, since a normal Po2 of a resting person is 40 mmHg and exercises lower Po2 levels. A normal resting oxygen level  should be about 94% with no added Oxygen. I)Which of the symptoms has described are due to lack of oxygen and reduced oxygen exchange at her tissues? Cari’s symptom of â€Å"panting like a dog† is due to the lack of oxygen and reduces oxygen exchange at her tissues. J)As Cari’s Pco2 rose, how was the oxygen-carrying capacity of hemoglobin affected? The oxygen carrying capacity of hemoglobin with rising Pco2 will decrease since CO2 will take O2’s seat on the short bus. K)How would you of expected Cari’s decreased Pco2 and alkaline blood pH to have affected her breathing? As acidity increases (pH decreases), it enhances the unloading of oxygen from hemoglobin. L)How would administration of oxygen enhance Cari’s central drive to breath? Giving Cari proper steady flow oxygen will keep her body from having to work harder to breathe. M)Which anatomical structures in Cari’s respiratory system were initially involved? N)Why was Cari plagued with a chronic smoker’s cough? Because Cari is a smoker this has caused the cilia in her respiratory passages to become irritated. O)Which damaging effects of tobacco smoke led to Cari’s impaired respiratory defense mechanisms? Impaired alveolar macrophages can lead to the impaired defense. The physiological sites and mechanisms by which nicotine acts on the brain. P)How did the pneumonia affect Cari’s lung function? Pneumonia can reduce the ability of the lungs to allow oxygen diffusion across the alveoli.

My Adventure

My Traveling Adventure The wind hummed past my head, and I noticed off to my side that the sky was starting to clear and that the water surrounding me was becoming a brighter shade of blue. The features of my destination were quickly becoming more distinguishable with each second that passed. Only fifteen minutes before, the features coming into view had appeared as small white dots across the horizon. Looking at my small digital watch, I noticed that the time was 3:45 p. m. , five minutes away from the island of Islesboro. The voyage across Penobscot Bay to Islesboro was one of excitement for me.The excursion to Islesboro started in the coastal town of Lincolnville, Maine. Waiting in the parking lot of the Lobster Pound Restaurant, I frequently saw young children frolicking across the sandy Lincolnville Beach off of Route 1. The smell of freshly cooked seafood and salty sea air mixed together while I sat on one of the bucolic wooden benches along the shore. The Margaret Chase Smith, the Maine State Ferry Service's ship that ventured to Islesboro and back, quickly docked at the end of a long wooden pier strewn with barnacles.The ferry navigated back and forth between eight monstrous black rubber pads jutting out from the water until it finally halted. The rusty metal ramp lowered onto the deck of the ship as cars started their loud engines, intruding upon the tranquility of the scene. My grandfather and I cautiously walked onto the ship after all the outgoing cars had departed. We gave the attendant our tickets and then watched the cars behind us drive onto the ferry like young children following their grade school teacher.After rushing up the water-coated staircase to the observation deck, I instinctively ran over to one of the large, four-foot windows in the observation room. My grandfather approached me and lifted up the heavy glass window. I loved feeling the cool sea breeze rush past me. As a child, I adored scavenger hunts, and the zenith of my voyage was when I rushed up to the ship's fire plan document displayed for general viewing above the ship's main water fountain. I searched the ship with my grandfather for all of the fire extinguishers, returned to the map to observe if there were any that I ad missed, and then journeyed again to find the unnoticed extinguishers. I proceeded to do the same for the life preservers, life jackets, and even the water hoses. My grandfather, waiting at the front of the observation room, assisted me up the stairs to the upper deck; by that time, enough time had passed so that the trip was almost complete. The top level of the ship was less active than any other place on the ship. Few people had the courage to stay on the windy, cold deck above the observation rooms. The only sound on the third level was the rumbling thunder of the electrical motor escaping from the captain's chamber.An unpleasant metal chain bearing the simple â€Å"CREW ONLY† sign guarded the white cabin. I had found it to be an ideal location to take panoramic pictures of the surroundings. Focusing on the horizon, one could obtain a perfect picture of nearby Mt. Battie in Camden or the Islesboro lighthouse. It was also an outstanding place to grasp the railings and look over the side of the ship, noticing an occasional whitecap or piece of driftwood floating in the overall calm sea. Another of my favorite locations on the ship was standing at the bow of the ferry, clutching in my hands the rusty metal chain barricading the exit.From this site, I was able to see everything directly in front of the ship and view the entire Islesboro dock as it rapidly approached. It had been from this location where I spotted a porpoise emerging from the bright blue ocean depths; I had also observed an enormous oil tanker voyaging up the bay to its port in the town of Searsport, fifteen miles north. The tanker's figure loomed like a rain cloud over the horizon in front of the boat; as we approached, we were able to ide ntify the major features of its cargo.Nearing the port at Islesboro, I smiled as I looked up at my grandfather. The first landmark I noticed was the Grindle Point Lighthouse. We had made a pledge to each other to see as many Maine lighthouses as possible during our years together. The green and red Grindle Point Light attracted visitors who could journey up the stairs to the source of the light. Continuing to stand at the bow of the ship, I saw the residents and visitors to the island desiring a ride back to the mainland. The large rubber hands of the dock led the boat into its proper position to unload.The ride over to the island of Islesboro had been exciting for me throughout my life. It was very meaningful to me because it had always been something I enjoyed doing with my grandfather. Of the many voyages we had embarked upon, the Islesboro trip epitomized all of the experiences we enjoyed doing together. I have traveled on many boats as I have become older, such as the Bluenose to Nova Scotia and the Steamship Authority's ferry to Nantucket Island, but none have had more of an impact on me than my first ferry ride on the Margaret Chase Smith.
