Organic compound boiling points Essay Example | Topics and Well Written Essays - 1000 words

Organic compound boiling points - Essay Example In order to figure out the order of organic compound boiling point, it is important to understand their trends. The important thing to make into consideration is that the boiling point is usually indicative of the force strength bonding its molecules together. When many molecules stick together, they will consequently need more energy to break the bonds and release the molecules as gases. Three important trends are considered including branching, which decreases the compound’s boiling point, and the number of carbons as boiling points increases with the increase in carbon atoms. Additionally, the relative strength of intermolecular forces is important (Hill & John, 2011: p32). The strength of the bonds in descending order is; Ionic> Hydrogen bonding> dipole- dipole> Van der Waals forces of dispersion. The influence of these attractive forces is dependent on the present, functional groups. The first trend is the strength, relative for all four compounds, of the intermolecular f orces. Molecules that are held together by dipole- dipole interactions, formed by the polarization of C-O bonds have a lower intermolecular energy when compared to compounds with hydroxyl groups, which are, in turn, capable of forming hydrogen bonds (Macomber, 2009: p11). Organic alcohols have significantly higher boiling points than other organic compounds because of this property, as can be derived. Molecules that have relatively the same molecular weights have their boiling points determined by the present, functional group. 3-Methyl-2-Butanone has a dipole-dipole intermolecular interaction model, and so it has a significantly low boiling point as compared to the other organic alcohols with hydrogen intermolecular bonding (Macomber, 2009: p12). The positive end of one molecule is attracted and bonded to a negative region of another molecule. For molecules with a similar functional group, such as the organic compounds under investigation, the boiling points increase with a rise in molecular weight. The key force that connects molecular size and intermolecular strength is the Van der Waals forces of dispersion that are proportional to the molecules’ surface area (Mehta & Manju, 2009: p29). Therefore, as the length of the chain increases, the surface area of the molecules also increases. Consequently, this results in an increased capability of the molecules in the compound to be attracted to each other. As the length of the chain increases, regions where they line up with each other increase. Each interaction may not be worth a lot, but added up over the entire chain length, the Van der Waals forces of dispersion have the ability to exert tremendous effects (Mehta & Manju, 2009: p29). 1-Hexanol has the highest molecular weight, coming in at 102.67 g/mol1, thus provides more surface area for intermolecular interaction. With the increased energy required to separate the molecules, the boiling point is high. Both 1-Pentanol and 3-Methyl-1-butanol have a mo lecular weight of 88.15 g/mol1, which is still higher than 3-methyl-2-butanone, which has a molecular weight of 86.13 g/ mol. Molecular symmetry is yet another by-product of Van der Waals forces of dispersion’s dependence on surface area. The straighter the compound’s molecules are, the better they line up, as well as bond. The spherical the molecules become, due to branching, the lower the surface area left for intermolecula

Managing Patient safety Assignment Example | Topics and Well Written Essays - 2750 words

Managing Patient safety - Assignment Example The person on whom the medication/ treatment is administered is harmed, and the person who recommends, performs or prescribes the use of the treatment is at fault (MAC, 2010). Each year more than 98, 000 individuals have fatal outcomes medical errors. The errors may arise as a result of doing the wrong treatment wrong treatment, going ahead with the treatment with insufficient information, or due to inefficient processes. About 10 to 20 % of the medical errors are as a result of errors in prescription of drugs or known as ‘medical errors’ (Patel, 2004). The cost of medical errors are very high and this may result in longer hospital stay, post-treatment complications that require a lot of care, etc (Patel, 2004). A more universal definition of a medication consists of any deviation away from the normal intention, expectation or desirability. There are many other ways of perceiving errors includes psychological ways, sensory events, perceptual occasions, cognitively, motor events, any action in well-managed system, and a negative output in a controlled environment Usually an error is related to an adverse effect and even if errors are not caused, they can still occur. For instance even if a drug is perfectly administered according to doses, indications, contraindications, prevention of interaction, etc, an adverse event can still occur as the (Kopec, 2007). Goldberg 2001 considers that the medical errors may have a serious effect on the system such as increasing the patient stay by a couple of days, which adds on to about a spending of $4600 per patient. Overall, with the total number of medical error cases reported every year, about 2.4 million hospital days would be spend and $9.3 billion. The impact is that patients have longer stay (LOS increased), the return to work is longer (indirect costing), and both these direct and indirect costing is preventable to a large extent (Patel, 2004). Most of the medical errors occur at the rate of 1 per day in a hospital, and they have the chance of causing serious negative outcomes for the hospital. Following the medical error, the aggrieved patient has the right to seek damages and compensation. In the year 2008, Medicare declared it would no longer cover for preventable medical errors in healthcare. Today with the introduction of such measures from the CMS and insurance companies, greater efforts are being laid in reducing medical errors as the hospitals are being held responsible (Patel, 2004). A medical error can be related to various aspects of healthcare including:- On a large scale, it is found that from the physician quarters about 57 to 60% of the errors can be prevented if a computerized ordering system is implemented and can be used appropriately (Maganelli, 2009). Patient Safety According to the AHRQ, patient safety is defined as â€Å"...as a discipline in the health care professions that applies safety science methods toward the goal of achieving a trustworthy system of he alth care delivery...’. Here greater efforts are being placed on trust in the healthcare delivery system (AHRQ, 2008). According to the IOM, patient safety is defined as â€Å"...the prevention of harm to patients...† They have placed greater emphasis preventing errors, learning from past errors, building a culture that is safe for the patients including efforts from organisation, professionals and the patients (Mitchell 2008). During

Research a Fortune 500 company Paper Example | Topics and Well Written Essays - 1250 words

A Fortune 500 company - Research Paper Example Introduction Wal-Mart is regarded as an American based multinational retail business corporation. It is one of the top companies which regained its position in the Fortune 500 list as per the 2012 report. The company emphasized providing quality products to the customers at a reasonable price which supported it to regain its position in the market (Duke, 2012). The management and the marketing strategies that adopted and used by Wal-Mart have a great impact on its increasing sales and the revenue earned. The foremost reasons for the success of Wal-Mart include its effective management, making deliberate efforts to attain its vision and growth among others which are in turn providing the business of the company an edge over others. Management and Marketing Strategies Wal-Mart developed a business model which focused on providing greater satisfaction to the customer with the deliverance of low price products to them. The management of the company followed upon developing its marketing mix strategy. In terms of analyzing management strategies of Wal-Mart, it can be viewed that the management of the company took steps to offer reasonable prices to the different product ranges that they deliver to the customers. The management segments the product type based on the buying capacity of the individuals. In relation to marketing strategies, the company emphasized promoting its broad assortment of products through using hoardings, leaflets and offering special discounts. In this regard, it can be affirmed that the management of the company desires to attract the customers by creating a positive brand name and recognition in the business markets where it operates. Relating to marketing strategy, the management team of the company developed a slogan as a way of promoting its varied products i.e. "Everyday Low Prices."Â   Continuous innovation and the use of technology for making the customers more satisfied are the other managerial approaches that used by Wal-Mart. It can be apparently observed that technology innovation at Wal-Mart typically involves process and service invention that helps in reducing operational costs and time at large. In this context, the management followed three policy goals i.e. respect for individuals, facility to customers and determination for excellence (Hayden et. al., 2002). Different Business Life Cycles that Endured By Wal-Mart The Prosperity Phase- This phase is regarded as the growth phase of any company which is marked by strong economy and market presence. In this similar concern, Wal-Mart maintained this particular phase by offering "high-quality," along with branded products at low prices and also by forming several stores in small towns. Wal-Mart uses the discount merchandising strategy in order to increase the demand and the sales of its products and hence accomplished superior competitive position over others. In relation to this particular phase, the company is growing rapidly due to diversification strateg y that it follows and expanding its outlets in small towns. Another reason for the company to flourish in this modern business market is focusing on delivering high customer services. Due to excessive demand of the products, the management of the company absorbed more employees during this phase (Hayden et. al., 2002). The Recession and Recovery Phase- This is the business phase which exhibits expansion by a significant level. This particular pha

Discuss the role played by Mr. Morrison Essay Example for Free

Discuss the role played by Mr. Morrison Essay Mr. Morrison symbolises the strength of Afro-Americans in the face of adversity. He is a source of courage and protection for the Logan family, acting almost as a guardian angel when papa is not home. There is an air of myth surrounding Mr. Morrison, created by factors such as his stature, his deep voice and scarred features. This makes him an interesting and thus successful character for Mildred Taylor. When the children first meet Mr. Morrison, his description relates directly to Mildred Taylors imagery. The attention that she pays to the significance of trees as an emblem of strength, influences her description of the powerful Mr. Morrison: The man was a human tree in height, towering high above papas six feet two inches. The long trunk of his massive body bulged with muscles The living strength and permanence of trees are a symbol of the strength which the black community draws from its history, tradition and inheritance, and the roots which have been put down in their land. Thus, the description of Mr. Morrison is in keeping with such imagery. The timing of Mr. Morrisons arrival assists Mildred Taylor in developing tension and suspense. He arrives on the scene in the wake of the news of the attack on The Berry Family. Mr. Morrison, we learn, was wrongly accused of starting a fight and then sacked from his job. This gives us an example of institutionalised racism and also hints that there may well be more incidents and fights. The children immediately warm to him and are deeply fascinated by his giant-like appearance. Mr. Morrisons attributes make him immune to the physical threats by which the local whites terrorise the black community. This gives the children courage and inspiration. As a result he is a figure who earns Staceys respect. Stacey becomes much closer to Mr. Morrison after he makes it plain that he will not be reporting the matter of the fight to with T. J to Staceys mother. Indeed, such is Mr. Morrisons positive influence, that Stacey shows increased maturity by telling his mother about the fight himself. On their way back from shopping in Vicksburg, Papa, Stacey and Mr. Morrison are ambushed by the Wallaces. Mr. Morrison shows his tremendous power by taking on three attackers and badly injuring two of them. In the following chapter he again demonstrates power and shrewd judgement too by lifting Kaleb Wallaces truck. This act is enough for him to avoid being drawn into fighting whilst still standing up for himself. By checking the truck for a gun first, Mr. Morrison shows an admirable measured determination not to be bullied. Furthermore, Mr. Morrison is a vital calming influence upon the headstrong Hammer when the childrens uncle is seeking to avenge Cassies humiliation in strawberry. The image of Mr. Morrison sat watching on the porch for the nightmen is a very powerful one. To the Logans he is a guardian angel figure, who protects with great strength, yet is otherwise the perfect example of calm. In the stories he tells to the family we learn of an horrific past in which his family were murdered by racists. His scars symbolise the healing power and capacity to endure that are characterstic of the persecuted black people. His voice like the roll of low thunder further emphasises Mr. Morrison as a key symbolic figure in the book, as this simile echoes the title.

Project scheduled, control and reporting Contractors system of project planning scheduling and monitoring is designed to provide comprehensive planning services to the project management team. This system is instrumental in devising realistic schedules establishing checkpoints, keeping overall watch on the progress, deviation from schedules, pinpointing the problem and recommending areas of corrective actions. The details are given below: 6. Planning Scheduling 6.1 Proposed Schedule and overall project schedule The proposed project schedule is submitted along with this proposal. This indicates the project starts date, end date and major milestones of the project the proposed schedule is prepared in the form of bar chart schedule. On award of the control, the proposed schedule is converted into an overall project schedule in the form of squared PERT network on time scale. This network includes overall engineering, procurement and construction duration as well as critical and near critical items for each system. This overall schedule forms the basis for execution of the contract and is used for corporate project review. 6.2 Master Network For project control, master network is prepared for the project, master network is updated internally every month, this is revised if (i) The overall project schedule is revised, (ii) There is a major change in the scope of work, (iii) unforeseen events beyond contractors control. The master network forms the basis for detailed scheduling and project control. 6.3 Function Schedules At the level of the executing departments, functional schedules are prepared for all functions, viz. process, residual engineering, ordering and delivery. Standard Networks for various functions are used for sequencing various activities in the schedules. These schedules are also used for scheduling projects physical progress and its measurement. 6.4 Key Construction Network This network is delivered from master network. This is made, work area wise, on time scale The number of networks to be prepared depends upon the workload into which the plant is divided. These networks are prepared at a time when engineering and procurement activities have sufficiently advanced and construction activities are about to begin or major milestones such as deliveries of equipments at site, start and completion of civil works, mechanical erection etc., are about to be achieved. 6.5 Reports Basically, three types of reports are produced. First type of report contains activities to be performed in next two months and is known as Activity List. Second type of reports gives the status of drawings, materials, etc. and is named Status Report, which highlights the deviations and exceptions and immediate actions. The Third Type of Reports is the one, which summarize progress report at various time intervals. 6.6 Monthly Progress Report Monthly progress report is basically meant for Client. This report gives a comprehensive coverage of engineering, procurement and construction activities carried out during the month under review. The monthly report apprises the Client of the progress of the project and holds up if an in achieving the progress.

Types of Waste

Types of Waste Waste is known as a matter which current users have no purpose of, or it is known as a matter which can be harmful to humans, animals or the environment. Waste can be divided into two categories, general and hazardous waste. General waste is waste that does not harm humans, animals or the environment. For example household waste, garden waste, building rubble, dry industrial and commercial waste. Hazardous waste is more likely to cause danger to humans, animals and the environment. This waste is based on the chemical reactivity, explosives, corrosive and radioactive. Waste Found In the Community of Edenvale There is many different waste found in the community which affect the community. The types of waste found in my community are agricultural waste which comes from animal products and the production of crops. This waste can be recycled. Biodegradable waste is a type of waste that will go back into the soil and nature. This may include garden waste, animal waste, fruit and vegetable leftovers. This waste can be composted. Garden waste is known as grass clippings, weeds, tree branches and this can all be composted. Bulk waste is large waste, such as broken appliances, furniture and outer parts. Almost all of this waste can be reused or recycled. Trade waste is waste is generated by shops, offices, or commercial places. Construction waste is found on residential premises. This waste includes batteries, empty paint and pesticide containers. Some of the household waste is recyclable. Industrial waste is waste that comes from industrial and manufacturing processes. Some of this waste is haza rdous. Intuitional waste is found in schools, hospitals, research institutions and public buildings. Medical waste is known as any solid or liquid waste which is generated in treatments. The Waste plan in my Community In my community the waste management plan for households is that waste is collected once a week. Businesses are different and get waste removed twice a week depending on how much waste is generated. Industrial waste is also collected once a week. It has been working effectively because the municipality has had no complaints and customers are happy with the system. The community also stays clean by means of the council collecting waste around bins so that the community will stay clean. Hazardous waste containers are also being provided and specialized companies deal with this waste. People that dump illegally get high fines. Public roads are being taken care of by litter being picked up by services five times a week. In the CBD litter gets picked up seven days a week. Free standing pole bins get emptied daily. Informal Settlements around my Community Some informal settlements where waste is not managed well is in the CBD, Hillbrow, New Town, Alexandra Township, and Jeppestown. The pollution comes in the form of dust from gravel roads, lack of clean running water, lack of regular refuse removal, broken and non-maintained sewerage pipes, absence of toilet facilities and ignorant littering. Due to the overcrowding of the informal settlements with migrants who are unemployed, and are not able to pay housing rent leads to a decay of flats and houses. In Alexandra some people still use the bucket system which increases the contamination from sewerage in the environment, and some people can get a wide range of illnesses. The organic waste attracts rodents and insects infestations. Poverty and lack of knowledge in these areas lead to littering, overflow of broken sewerage systems and unmanaged waste. A waste management plan for the informal settlements is that refuse is removed twice a week by means of bulk containers and street hawkers are issued with refuse bags weekly. â€Å"The metropolitan council wants a waste disposal strategy; identification of waste disposal sites, establishments, operation and control of waste disposal sites.† The community water supply and sanitation programs aims to ensure all South Africans have access to clean water. The metropolitan also wants to prevent invasion of industrial sites. Some solutions that can help reduce waste are: Waste Avoidance, Prevention and Minimization: system to ensure the appropriate design promotion, optimizing operating procedures and good house keeping for all waste generating processes. Forecasting potential situations in which accidents and spills can cause unscheduled waste emissions. Recovering, Recycling and Reuse: Reduction in the waste stream. Recycle materials such as taxes on waste or subsides for waste cycling, and also extraction and utilization of landfill gas. Treatment and handling: Ensuring that waste is appropriately treated and processed to their disposal in accordance with laws, regulations and guidelines. Storage and Final Disposal: Timely identification investigation and construction of environmentally and socially acceptable waste disposal facilities. New innovative ways of managing waste in disadvantaged communities are required. We can move towards collection by paying people to collect litter and involve the community in programs. We can improve the awareness to the public with regard to waste. Allow people living in informal settlements to regain their dignity by providing sustainable, affordable sanitation. Polokwane Declaration The aim of the Polokwane Declaration is to reduce waste by 50 % respectively by 2012 and have a plan for zero waste by 2022. In order to achieve their goals they must engage more closely in a realistic and practical manner. Conclusion In Gauteng waste management is lacking it appears there has been an increase in waste per year between 1998 and 2003. It also appears that Polokwane Declaration of zero waste remains optimistic. Hazardous waste has decreased as a result of improvement in industrial activities. Recycling initiatives are being adopted and are successful. The importance of the public awareness of waste and recycling should be made aware and action plans formulated.

Elements of Poetry and Essay Writing :: Education, Writing

I was surprised to find that I could use so many of the techniques that poets use in writing my own essays. For example, by choosing certain words, I can set the tone for the essay and demonstrate certain attitudes. Also, I can take advantage of several technical methods, such as abstractions, assonance, and figures of speech to make an essay more interesting. Further, I think it is important to try and understand the poets meaning behind their word choice. After analyzing the poems of John Donne, Anne Bradstreet, and Robert Frost, I will discuss how I think certain elements can be used in my own writing. Anne Bradstreet used words such as â€Å"loved†, â€Å"happy†, and â€Å"reward† to set a positive tone (963). The author’s attitude came across as grateful and appreciative. In contrast, Robert Frost chose to use words such as â€Å"perish†, â€Å"hate†, and â€Å"destruction†, which displayed a negative tone and attitude (1009). I never really gave this much consideration before, but I think I could use this technique in the future. By choosing the correct words, I can make sure the readers are interpreting my writing as I mean it to come across. I also discovered several technical methods that can be used in my essay writing. This is another area that I never really paid attention to. Sure, I have used some of them, but never knew what they were called or understood the full effect of them. Abstractions and several figures of speech were amongst some of the methods that were found. For example, â€Å"Batter my heart, three-personed God† (Doone 988), â€Å"To My Dear and Loving Husband† (Bradstreet 963), and â€Å"Fire and Ice† (Frost 1009), abstractions were used. Abstractions are words that we use to describe something that has no concrete reality (Charters 787). For example, in Doone’s poem, the author used words such as â€Å"weak† and â€Å"untrue† (989). Bradstreet also used this technique by using the word â€Å"love† (963). And finally, Frost’s word choice was cleverly utilized with using â€Å"desire† and â€Å"hate† (1009). These are also considered examples of figurative speech in that they use simile or metaphor in describing the subject (Charters 795). I feel by taking advantage of some of these techniques, I can make my essays more interesting for readers. To add, I found several figures of speech techniques such as metonymy, apostrophe, hyperbole and symbols were used in Anne Bradstreet’s poem â€Å"To My Dear and Loving Husband† (963).
