Nuclear Waste Disposal Essay -- Radiation Pollution Papers

Nuclear Waste Disposal As the millenium approaches, we are faced with the problems created by our technological advances. Everyday we are forced to see the results, from acid rain to polluted beaches. But there is one problem in particular that will probably out-live our generation and the generation which has created it. If properly contained and monitored, it has little affect on us and our environment. However, once it is free of it's containment, it is a destructive and deadly force. This problem is nuclear waste. Thirty thousand metric tons of spent fuel rods from power reactors and another 380,000 cubic meters of high level radioactive waste, have been produced in the United States since the beginning of the nuclear age. Presently, these fuel rods are stored at the nuclear reactors in water filled basins and accumulate at the rate of six tons per day (Whipple, 1996). As the populataion increases, so does the demand for electricity. If we continue relying on nuclear power to provide our electricity, we will continue producing more and more nuclear waste. Greater use of nuclear power and volumes of waste mean a greater chance of accidental release of radiation into the environment. Radiation How it is produced How does radiation in our environment affect us? In order to understand how radiation affects us, we first must understand how it is produced. Fission is the initial step. It is the splitting of uranium or plutonium atoms which produces radioactive "fission fragments" and "activation products" (Bertell, 1985). These products then ionize normal atoms, which leads to a sort of domino affect microscopically. This chain reaction can also cause activation products to be produced by causing chemicals in the air,... ... 1982. http://www.public.iastate.edu/smevela/policy.html.

PLATE

The protein fraction from 70 percent saturation of recrystallised ammonium sulphate was found to have the maximum protein content (19.6 mg/g flower) and hence it was selected for further studies and is abbreviated as PAF in the present study. 4.2.1 Characterization of the selected PAF by Native PAGE and SDS PAGE The selected PAF was characterized by column chromatography. This showed a single peak and was further characterized in native PAGE and SDS page. The results are shown in Plate the SDS-PAGE analysis of the ammonium sulphate precipitated protein extract showed 15 different protein bands with good visibility in CBB R250 staining method (Figure). PLATE CHARACTER IZATION OF PFPa BY PAGE AND SDS PAGE A – Standard Protein Markers; B – PAGE; C– SDS PAGE Each fraction showed a number of major and minor bands indicating several proteins. Of the several bands obtained in 70 per cent saturation of ammonium sulphate, the major band alone was eluted. In order to find out the presence of subunits in this band, it was further subjected to SDS PAGE. The results showed one major protein indicating the absence of subunits. The molecular weight of this protein was found to be 99 KD when compared to the standard molecular markers. 4.3. Fifty percent effective dose of selected protein fraction of Plumeria alba The free radical scavenging capacity of PFC was tested by its ability to bleach the stable DPPH. The DPPH (2,2 diphenyl -1- picryl hydrazyl) radical scavenging activity was carried out using different concentrations of PFC (Figure). The radical scavenging activity was found to be dose dependent. Figure Percentage Free Radical Scavenging Activity of Selected protein fraction of Plumeria alba The protein fraction of Plumeria flower extract showed the dose dependent DPPH radical scavenging activity. From the graph, the 50 percent effective concentrations of these were found to be 28 Â µg and 35 Â µg and used in the further studies. Free radicals and their scavenging systems play important role in the healing of normal and delayed types of wounds.

Shyuret al. (2005) also reported that the scavenging activity for free radicals of 1,1diphyryl-2-picrylhydrazyl (DPPH) has been widely used to evaluate the antioxidant activity of natural products from plants. The antioxidant activities of the leafy vegetables of India were measured in different systems of assays such as DPPH assay, super oxide radical scavenging assay, hydroxyl radical scavenging assay and lipid peroxidation assay and IC50 values were calculated (Dasgupta and De 2007). 4.4. Matrix-Assisted Laser Desorption/Ionization – Time of Flight Mass Spectra (MALDI-TOF MS) MALDI-TOF mass spectra were used for the analysis of peptide mass fingerprinting and MS/MS ion search identification of the in-gel trypsin digested protein fragments (Figure 5), selected peptide masses were submitted to Mascot (http://www.matrixscience.com) for SwissProt databases search. There was no conclusive match in peptide mass fingerprinting, since MS/MS ion search program was selected for further identification. The MS/MS ion search in the NCBIProt database revealed that, WRKY transcription factor WRKY24-like isoform X1 [Juglans regia] (Figure 6-7) with the protein score of 81 (Protein score is 10*Log(P), where P is the probability that the observed match is a random event. Protein scores greater than 80 are significant (p

Family Assessment and Intervention

Family Intervention Movie Assignment â€Å"Meet the Parents† One of our main objectives as future counselors is to understand individual clients is to first gain an understanding of family background. Working with family from a systems perspective, the counselor is able to gain an understanding to the ways in which family members interact, what the family norms and expectations are, how effectively members communicate, who makes decisions, and how the family deals with needs and expectations (Edleman & Mandle, 2002). In the concept of systems theory, a family can exist within a community (suprasystem) and at the same time have smaller relationships within that family (subsystems). By composing genograms, or family tree, one can see information on family relationships, health patterns, occupations, and religion. By composing an ecomap one can see information on how a family and its members interact with larger systems or smaller subsystems. The term family can be defined as â€Å"a group of individuals who are bound by strong emotional ties, a sense of belonging, and a passion for being involved in one another's lives (Wright & Leahey, 2000). After watching the movie, â€Å"Meet the Parents† I decided to watch the whole movie to see where it would be that the intervention would start. The scene where â€Å"Greg† tries to get the cat off the roof and ultimately to please Jack his girlfriend’s father he goes to a local animal shelter to purchase a look alike cat for the family cat that ran away, named Jinx (Which I thought in hindsight the cat’s name is the complete situation Greg finds himself in†¦jinxed). Once the family gets home and finds ‘Jinx’ has destroyed the dress and the house before his youngest daughter’s wedding everything hits the fan†¦emotions rage and Jack and Greg are starting to really express themselves. I think Greg does this because he feels he has nothing to lose. The interesting part is how this whole fiasco sort of brings the family and friends together†¦here is where I would begin my interview.

buy custom Social Perceptions Impact on Managing Diversity essay

buy custom Social Perceptions Impact on Managing Diversity essay Every individual has a degree of socializing with the rest. The social attitudes, however, are important as they influence most of the activities that we engage in. These are very important in the determination of managing diversity as discussed in the next paragraphs (Gardenswartz Rowe, 1998). The first social perception that well discuss is the stereotypes. These are beliefs about a particular group or characters. They categorize individuals according to various criteria while associating them with given traits which may be incorrect. They are not necessarily negative but may not be accurate. They can lead to poor decisions, undermine job satisfactions and create barriers for a particular group of individuals. Social impacts also give a limitation as to what information an individual o group takes. One may filter important information considering it not fit for what one believes is best. Some information cannot be archived from its sources if the concerned individual is unwilling to give out the information. The social perceptions will influence the kind of judgments delivered. A group or management can dismiss a great idea basing their arguments on their naivety. This will discourage innovations and diversity. In conjunction to this, poor hiring decisions are likely to be made. The decisions thus limit the new ideas from getting their way into an organization. The customer needs may not be satisfied when a company is used to a particular group. A company that produces goods and services for a particular gender is limited to it and will never (unless changes are introduced) know what others love. There are many cases of workplace vulnerability reported. These are as a result of social differences. The later is that a particular group has a negative perception of the later. They limit diversity. Some social styles such as sexual harassment among others make potential pioneers afraid of getting into a particular career. They fear the worst and take what they think are safety measures. Social attitudes lead to poor career planning. This makes most individuals lack the capability to handle some important job requirement leading to poor employment and non-diverse employees. The social lifestyles of individuals affect their relationships at every level and finally rest upon a negative impact on diversity. Individual should learn to have flexible lifestyles in order to encourage innovations and diversity. Buy custom Social Perceptions Impact on Managing Diversity essay

American Airlines Essay Example

American Airlines Essay Example American Airlines Essay American Airlines Essay Ninety-Four marked a significant increase in turnover and number of staff employed but a dip in profits. This was not seen as a concern as 93 and 94 were seen as years where the company was making big capital investments to improve future efficiency and capacity. For instance facilities at Gatwick and Heathrow were improved and the Club Europe brand was launched as a further incentive for business customers. BA teamed up further with Qantas and set up two franchises with Logonair and GB Airways in 94 and a further one at the beginning of 95 with Manx Airlines Europe. The economys of scale and new destinations that were offered by these companies allowed further cost cutting by BA but explains the increase in staff numbers. Ninety-Five, Ninety-Six and Ninety-seven were good years for BA. Profits doubled to above those that were being reached before the gulf war and turnover and employee numbers also went up to cope with increasing demand. The economy was in good shape and John Majors government secured new agreements with the USA allowing BA to occupy more slots at US airports. Shortly after BA sold its stake in USAir and went into an arrangement with the bigger American Airlines. A new three-year plan to revolutionise air travel is announced at a cost of i 500 million and is aimed at premium Business customers, the market which was responsible for BAs current large profits. New franchises are announced including overseas ones in Denmark and South Africa and agreements with Canadian Airlines. These arrangements go further towards developing BAs brand and reducing costs through economies of scale. Union problems were settled and cuts or freezes were made on cabin crew and ground staff wages. 1998 saw BA launch Go a no frills airline which would not compete for the same clientele as the increasingly business orientated BA. Manchester airports new 75million terminal was opened. Turnover and Staffing levels continued to go up but alarmingly profit halved. Thus began a time when budget airlines boomed and business airlines suffered. However Go was finding it difficult to attract customers from competitors easyjet and ryanair. In 1999 BAs profit after tax went into the red for the first time since privatisation. BA continued to forge relationships with other international airlines. In particular Spains Iberia who they bought a nine percent share of in February. Turnover continued to rise as did customer numbers and staff levels. The failure of Go, was a contributing factor to BAs worst result since 1982 (BA Reports and Accounts, 1999-2000, inside cover). In 1999, profits had taken a dramatic decline, with operating profit falling by i 358m, down to i 84m. Gross profit had also fallen by i 358m, down to i 261m. This fall in profits also had a negative impact upon investment in the company, with capital and reserves falling (BA Reports and Accounts, 1999-2000). These dramatic falls in profitability were caused by increased competition in the market, which led to competitive pricing and marketing. British Airways funds were getting used too quickly. The increase in oil prices also meant increased expenditure for BA. Things got worse for BA, with low employee morale, leading to poor customer service, which in turn deeply impacted upon BAs reputation (BA Reports and Accounts, 1999-2000). 2000 saw some return to form for the ailing BA. Turnover, Profits and Capital increased and cuts in staff were announced to try to curb the effects of the worldwide recession which seemed imminent. The figures for 2000, were an improvement, but were not back up to pre-1999 levels. One of the major reasons for this was the foot and mouth epidemic, which hit Britain in February 2000. This stopped a lot of people from traveling both out of but especially into the UK and badly hit BA. Also the petrol crisis boosted BAs expenses, and scared people into not traveling (bbc. co. uk). The grounding of Concorde after the Paris crash on July 25th badly hit the travel industry. It hit BAs upper and luxury class services including the business sector that they had been so carefully nurturing. In all this time of hardship, passenger traffic fell by more than 13% (telegraph. co. uk). 2001 looked promising; In May the airline reported a sharp rise in profits and revealed that it was making more money from each customer than it has done since it was privatised in 1987. The new chief executive, Rod Eddington, was being congratulated for turning BA around after years in the wilderness with former boss Bob Ayling. (news. bbc. co. uk/). He planned to stay true to the formula of concentrating on the premium business sector and so in June 2000 completed the sale of Go, BAs no-frills airline, making a  75m profit from its initial investment three years ago. Then, unbelievably the events of September the 11th occurred and within 2 weeks BA were announcing job cuts of over 7000, profit warnings were issued and competitors were going bust. Passengers were unwilling to fly due to safety concerns and the whole industry was hit hard. Suddenly the safety issue that had not grabbed the headlines for 10 years is again a priority and the mountain that BA had climbed since the Gulf War is bigger than ever. BA posted huge losses in 2001 with analysts predicting that it will take several years for the industry to begin to recover.

Here is How to Make Edible Glitter

Here is How to Make Edible Glitter Make your own edible glitter. Its easy and inexpensive and much safer for kids or to put on your face. Edible Glitter Ingredients 1/4 cup sugar1/2 teaspoon liquid food coloring You can use granulated white sugar or any of the crystalline sugars. Avoid brown sugar (too moist) and powdered sugar (not sparkly). Use liquid food coloring because paste coloring is more difficult to mix and may discolor when baked. Mix together the sugar and food coloring.Bake the colored sugar in a 350 F oven for 10 minutes.Store the sugar glitter in a sealed container, to protect it from moisture. Non-Toxic Glitter Recipe 1/4 cup salt1/2 teaspoon liquid food coloring Mix together the salt and food coloring.Bake the colored salt on a baking sheet at 350 F for 10 minutes.Allow the glitter to cool. Store the glitter in a sealed bag or container. You can mix either type of glitter with corn syrup or non-toxic glue for craft projects or stick it to your skin. It also sticks fairly well onto petroleum jelly for use on your lips. Because petroleum jelly is oil-based, it wont dissolve the sugar.

Intro to missions Essay Example | Topics and Well Written Essays - 1250 words

Intro to missions - Essay Example The paper also explains in detail the meaning of Missions and shows how the theme of Missions is the main focus of Missiology. Before we delve into the main areas of Missiology, it is important to look at the distinction between two important Missiology terminologies. The first terminology is the term mission. The term mission (singular) is used in reference to God’s mission in the world, or in other words God’s desire of reconciling all human beings to him (Rogers, 27). Missions (plural) on the other hand refers to the human participation in God’s work of reconciling the human beings to him. As we have said in the introduction, the main aim of Missiology is to prepare the prospective missionaries for the challenging and very important work of missionary. For the missionaries to succeed in their mission work, they should be adequately prepared to face the challenges of mission work. The preparation requires that, first; the missionaries should be well grounded in Theology. This is because as the work of any missionary involves living the Gospel in a radical way and helping the other people to know God and to give their lives to God, the missionaries should be well grounded in Theology. To be effective and successful in their work therefore, the missionaries should understand well the main aim and goal of mission work. This therefore means that the preparation of future missionaries should involve studying salvation history. According to the Bible, especially the book of Genesis, we learn that the main reason why God created human beings is to have a mutually satisfying relationship with the human beings (Rogers, 13). That is why even after man sinned against God in the Garden of Eden, God did not abandon man but He initiated the process of reconciling man back to him. Salvation history is all about this process of God reconciling humanity back to
