Availing Medical Facilities at the Doorstep-Samples for Students

Question: Discuss about the App designing for Online Medical Facilities. Answer: Introduction Working on a project and developing all the aspects related to it is a very crucial task. It ensures that the project should get completed in a smooth manner. A proper plan should be developed in which all the aspects which will indulge in the project should be focused upon (Petit, 2012). The project initiated is about developing an application which will help in availing medical facilities in the rural areas of Australia. An application will be developed which will be connected with the kiosk machines and with the mobile phones of the people living in the rural areas. Application on the mobile phones and kiosk machines will be designed in such way which is easy to use and manage by the people living in the rural areas of Australia. The project initiated will help in providing better services to the community and will help the people of Australia in managing a sustainable as well as healthy life (Skibniewski, et. al., 2012). Hence, a project is developed which will include a proper d escription of what are the aspects required to be taken into consideration before working on the project. It is being evaluated that the people living in the rural areas faces issues in getting proper medical facilities. Hence, by providing them such type of app will help them in managing the healthy life and will help the company in providing a 75% hike in the sale as Australia has various rural areas where the medical facilities are not much effective (Stanek, et. al., 2016) Expected Benefits/Current Situation And Market Opportunities Projects are developed for the welfare of the business. Aim of developing a new project is to generate more revenue and to ensure that more refined services could be developed (Thomas, 2015). There are various set of benefits which are required to be taken into consideration. But before evaluating the benefits it is necessary that various aspects should be focused upon like market analysis, SWOT analysis and output analysis. Market Analysis Market of online health service is a growing sector which is sustaining in the urban market. It is being evaluated that many of the people are using such type of services and are enjoying them as they are getting health tips just by making certain clicks (Too, Weaver., 2014). There are many of the health service providers who are providing consultations with the help of online applications in the urban areas. The online health services are sustaining day by day and are moving on a successful path. Taking this business to the rural areas will definitely help in the sustainability of the community (Cengage Lea Schwalbe, 2015). Providing instant services will help in attracting people of rural areas with the effect of which organization will move on the path of success and sustainability. SWOT Analysis STRENGTHS WEAKNESSES Plan developed will help in sustainability of the community There is no competition available in the rural areas Online Medical services has a growing market Helping the rural areas to growth is a noble cause in which government will also provide appropriate set of help for the initiation of project (Koltsov, et. al., 2015). It is necessary that the people of rural areas should provide the knowledge of app, because low knowledge will affect the sale of the product and services. Huge investment is required in the kiosk machine as well as app development. Availability of proper set of resources is really tough OPPORTUNITIES THREATS Low competition in the rural areas Has a very wide area to cover and attract people towards the application. Innovation is there which will help in the sustainability aspects and gaining proper set of market share. Failing to cover maximum rural areas could have a direct impact on the business. It could be possible that people of rural areas may not trust the online app and would rather prefer to visit health care centres. This will affect the sale of the business in near future. It could be possible that new competitors could enter into the market (Palma-Mendoza, et. al., 2014). This will have a huge impact on the sale of the products and services in the rural areas. Output Analysis Understanding the market and evaluating the SWOT analysis it could be evaluated that providing online health services in the rural areas will result in providing various set of benefits to the organisation. Market has a huge potential for growth as people available in the rural areas of Australia will definitely prefer to use the application (Patton, et. al., 2015). It is required that information camp should be organized in which information related with the kiosk machines and application should be provided to the people available in rural areas. This will help in attracting maximum number of people available in the rural areas towards the application. There are certain dis-benefits also which are attached with the new project like it could be possible that people available in the rural areas might not use the application and might prefer to visit the health practitioners directly rather than using the app (Mainga, 2017). Lack of knowledge will have a huge impact on the use of application. This will have a direct impact on the progress of the business and will affect the sale of the same. Project Requirements List and describe the requirements needed to carry out this project. To manage the project in an effective way it is required that all the requirements needed to carry out the project should be taken into consideration. To manage the project there are several aspects which are required to be taken into consideration these aspects are: Stakeholders analysis is required to be taken into consideration as it will help in understanding the requirements and needs they have (Martinsuo, Killen, 2014). This will help in managing their requirements and will help managing the project in an effective way. IT team is also required to be hired for the development of the mobile app and kiosk machine Kiosk machines are required to be purchased so that they could be availed in every rural area. Appropriate project management tool will be required to manage the same in a proper way And 4 systems will be required so that the application could be developed according to the requirement (Mishra, 2014). List and describe the possible assumptions for this project Assumptions are made which helps in developing the understanding with the future aspects which could incur. It is required that the assumptions should be made in an appropriate way and decisions should be made accordingly. It could be assumed that after promoting the app and description of the kiosk machine maximum number of people will get attracted towards the business and will help in sustainability of the same and vice versa (Mller, 2015). It could also be assumed that the project initiated will help in availing appropriate set of services in the emergency cases which will help in providing sustainability to the community. Assumption could also be made that this project will help in providing expansion opportunities to the organisation and will help in the sustainability aspects. List and describe the constraints for this project. Project management is an unpredictable aspect as it is hard to predict all the aspects in a proper way. There are certain set of constraints which could be left behind and these constraints could have a huge impact on the project progress (Pandey, 2008). It could be possible that the IT team could fail in testing the app properly due to which bugs in will left. This will have a huge impact on the implementation of the project to general public. It could be possible that people available in the rural areas may not have proper set of knowledge about the app. Hence, it will again have a huge impact on the progress of the project (Petit, 2012). Costs How much does it cost? Determining cost of the project proposed is one of the most important aspects attached with the project plan. It is important that proper analysis of the cost which will indulge in the project should be done as it helps in providing direction to the project developer and helps in managing the work accordingly. In the project proposed cost which could be estimated is $36000. It is a very nominal cost that will in paid by the organisation for the project. Reason behind this cost is that the organisation is already working in the rural areas and there are various centres which are already available in those areas. Hence, the main expense which will incur in the project process will be on the development of the application for mobile and kiosk machines and on the kiosk machines itself only (Skibniewski, et. al., 2012). There are certain other expenses also which will incur in the promotion of the app in rural areas. Therefore the all over cost estimated for the completion of the project is $36000. Activities Amount ($) App Designing 11000 Expenses on Kiosk Machines 11000 Expenses on IT team salary 10000 Advertisement 4000 Total 36000 Identify the tools used for cost analysis Cost benefit analysis is the tool which will be used so as to evaluate the cost which will indulge the project. This will help in evaluating the expenses which will incur and the benefit which a company will get from the expenses it has made on the project. Cost benefit analysis will help in estimating all set of requirements and will help in making the decision of whether the company should initiate the project or not (Stanek, et. al., 2016). In cost benefit analysis Net Present Value of the project will be calculated also it will include return on investment and will include break even analysis which will help in determining the payback period of the project. With the help of these aspects company will be able to make the decision of whether it should apply the project or not. Major Risks There are various set of risk factors which remain attached with the project. It is necessary that these risk factors should be taken into consideration so as to manage the project and maintain its requirements. Project management is a very crucial task which requires in depth analysis of all the aspects. Hence, it is necessary that the major risk factors should be evaluated and strategies should be developed to mitigate them (Thomas, 2015). Identify five (5) major risks Five major risks which are identified in relation with the project are: Unavailability of the Resources Unavailability of Funds Choice and Preferences of the target customers Natural Disaster Lack of leadership These are the five risk factors which could have a huge impact on the progress of the project. It is necessary for the project manager to make the predictions with the help of forecasting so as to gain appropriate set of information related with the risk factors (Too, Weaver., 2014). Discuss the risks involved and how they will be managed Unavailability of the resources will affect the progress of the project as no work could be processed without having appropriate set of resources. Unavailability of funds will have a direct impact on the project, it will have a huge impact on the functions of the project. Natural disaster is another aspect which can affect the project progress (Cengage Lea Schwalbe, 2015) Lack of leadership will affect the internal aspects of the project and will lead to misguide the team working in the project. Choice and preferences of the target customer will again have a huge impact on the project progress as it could be possible that people may not prefer to go with online services. This will lead to cause a huge loss to the company (Ong, et. al., 2016). Timescale How long will it take to complete the project? It will take 2 months to complete the project, which will also include the training of the employees so that they could work appropriately on the application (Koltsov, et. al., 2015). A step by step process will be provided which is required to be followed by each and every individual working on the project. It is important that the time provided for the task should be followed in an appropriate way so as to ensure that the project could get completed within the timeframe. List and describe the major milestones. Major milestones decided by the project manager for the project are: Evaluating the need of the project which will be done within 2 days. In this analysis will be done of why it is required to develop such type of app for rural areas (Palma-Mendoza, et. al., 2014). Project scheduling is another aspect which will be focused upon. Project scheduling will be completed within 5 days (Pigott Hobbs, 2011). Time keeping will be done which will be completed in 2 days Technical design will take 15 days as it will include various programming and developing of the app. Testing will be done for the 10 days in which all the bugs will be removed. And then training will be provided for 15 days to the staff members (Patton, et. al., 2015) Conclusion At the end it could be concluded that the project initiated will help in the expansion of the company. The project proposed will help in managing the requirement of the community and will help in providing a better set of support to the community. It could be evaluated that for a project it is necessary that all set of aspects should be taken into consideration and analysis should be done so as to provide a better set of support for the future success.

Macbeth Microtheme free essay sample

A smile could mean a real smile, though it could also mean anger, revenge, or deceit. â€Å"And nothing is what is not. † (1. 3. 155). This line being said by Macbeth, shows what’s underneath his layer of faithfulness: he starts to believe that the right thing to do is kill Duncan. It said after the witches gave the prophecy that Macbeth will become king and after Macbeth is announced Thane of Cawdor, showing that the prophecy may very well be true. Macbeth is expressing that he is confused about what to do – something that may seem right to him, will not seem right to the people around him. Macbeth seems like a very faithful man; he fought for Duncan, the king, and really cares about his friends and his country. Along with his confusion about his moral reasoning, he also expresses his shock for seeing the supernatural (evidently, witches aren’t a normal spotting). We will write a custom essay sample on Macbeth Microtheme or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Look like th’ innocent flower / but be the serpent under ‘t. †(1. 6. 76-77). Said by Lady Macbeth, this quote compares the difference of physical animals to the deceitful personality she wants Macbeth to persevere. A flower is innocent, attractive, and sometimes bland – unlike the look of a murderer. A serpent is cruel, dangerous, and sneaky: the exact qualities a murderer needs to do his deed without getting caught. At the beginning of the play, Macbeth’s personality tilts closer to the flower, while nearing the end, it clearly shows the other end of the scale (a serpent). The supernatural doesn’t appear in random situations; it always has a purpose. â€Å"Is this a dagger which I see before me? † (2. 1. 44). It is unclear whether it was a sign of the supernatural or a hallucination his feverish mind had made. But whether it was supernatural or not, it meant something. If it were his mind’s creation, it may have been a sign of his guilt and that it was just as easy to take his own life, as he had taken Duncan’s. If it were the supernatural, it may have been a sign that his troubles are not yet ending, and that he will use that dagger yet again later on, unfortunately, killing his friends and the people closest to him. Reality is, there was no dagger because when he reached out to grab it, his hand went right through it. False face must hide what the false heart doth know. (1. 7. 95) Macbeth starts to realize that what he has done isn’t all bad, and that since it’s done with, the time has come to hide the reality of it all. The quote literally means ‘You will act like nothing has happened and nothing is wrong. ’ Macbeth started out as a simple, faithful person; not having anything to hide until the witches told him about the prophecy and his wife told him to kill Duncan – which he did. Lady Macbeth on the other hand, seems very cruel at the beginning, but towards the end, we see how she’s become weak because of her sleep-walking and that she is racked with guilt. â€Å"The world is governed more by appearances than realities, so that it is fully as necessary to seem to know something as to know it. † – Daniel Webster. This quote perfectly explains that hiding our reality is human nature. Everyone errs and lies, no matter how great or small – including all the main characters in Macbeth. Without a false reality, there would be no such thing as deciet.

Enthropy essays

Enthropy essays If I had a choice to invent anything I wanted I would create an entropy machine of some sort. Even though the invention would inconsequently break the most ironclad law in science the first and second law of energy. The entropy machine would turn low quality energy into a higher quality energy source. Entropy means disorder of energy, which is basically heat, which is a by-product of organisms and human made machines. Low entropy cannot be used. Without high quality energy life doesnt exist because even our bodies use constant high quality energy and emits it back out as heat and waste matter. And the high entropy is not indefinite it will run out no one knows when though, but with the invention of the entropy machine life would keep Operating in all the universe. Though by doing this it breaks the law of energy, which says that all physical or chemical reactions energy is neither created nor destroyed may be converted. The ultimate destination of energy is disorder (low entropy) We cannot get more energy than the efforts we put in to get that energy cant get something for nothing and you cant even break even because it takes more high quality energy to turn something to a more useful form like getting electricity for example. If the high quality energy is all used up life will slowly fade from the universe. Thats one reason I would make this particular kind of machine so life would never be extinguished in the universe. The entropy machine after collecting the useless energy would then turn it into fossil fuel or some other needed energy that is running low, the energy from the machine whether fossil fuel or whatever would produce no pollution. Taking some of this disorderly energy from space or the earth would not affect the biosphere we live in. The entropy machine would also help to choke off the appalling amount of pollution that affects this planet. The only bad thing or slight nuisance is that the...

Evaluation of the Responses Made by Dretske as Pertains to Chisholms Assignment

Evaluation of the Responses Made by Dretske as Pertains to Chisholms Claims - Assignment Example It was the philosopher Fred Dretske who took to investigating the various claim that was made by the late Roderick Chisholm who postulated that intentional states could only possibly be mental states. In making this claim, Chisholm was seen to derive the claim mainly based on the thesis proposed by Franz Brentano the nineteenth-century philosopher in his book â€Å"Psychology from an Empirical Standpoint†. Chisholm’s Claim that Intentionality cannot be naturalized and Dretske’s Response to the Claim A key feature of various mental states is their actual content. An example is that in the event that I essentially believe it will snow, my actual belief as at the moment can be seen to represent a state of the weather and when I chance to see a dog, I become perpetually aware of that cat. My innate belief that it is eventually going to rain may be seen to be inaccurate or accurate, my perception as to the existence of the cat may be imprecise or precise and my desire to be loved my eventually be satisfied or unsatisfied. Brentano postulated that intentional states were essentially solely mental states and thus distinguished mental states from the physical states because they are objects of awareness and non-spatial in nature. Brentano further contends that this perceived ‘intentional inexistence’ is generally exclusive to psychical phenomena and that there are no physical phenomena that can essentially be said to have it (Feldman & Feldman 2008). The Intentionality of thought can basically be accounted through mental expectations, semantics, and language. All these factors serve to actively demonstrate psychological intention and therefore cannot be explained in non-intentional or non-psychological terms. For Chisholm intentionality cannot essentially be naturalized because it is impossible to identify any such psychological fact with a physical fact. For Chisholm, the use of various intentional sentences essentially means that all our currently existing beliefs about various psychological phenomena an essentially be sufficiently expressed through them although it is impossible to do so for physical phenomena (Feldman & Feldman 2008). A good example of this is the sentence ‘Diogenes searching for an actual honest man†, this sentence can be perceived to be an intentional statement because it is seen not to rely on the relative veracity of there necessarily being an honest man or not.  Ã‚  

The Jamarat Pedestrian Bridge Research Paper Example | Topics and Well Written Essays - 2750 words

The Jamarat Pedestrian Bridge - Research Paper Example It occurs that the Islamic Hajj pilgrimage is the largest congregation of people on global repetend (Samarid, 2010). About two million Moslem pilgrims observe Hajj during the twelfth lunar Arabic month. Activities commence on the ninth day and terminate on the twelfth. One of the activities done in Mina adjacent to Makkah is the ramy al-jamarat (Al-Haboubi, 2003). Jamarat was built to ease movement of pilgrims as early as 1936 and has been expanded several times. Apart a religious significance, the built structure serves as a vital logistics piece (Islamic City, 2009). Yet great efforts, the sheer magnitude of pilgrims turn catastrophic. Thus the old bridge is revamped by royal decree for the construction of a multilevel bridge (Islam portal). To define the necessary logistics involved in moving all pilgrims simultaneously, at set times, along stations spanning 10 miles, for about 2.5 million Moslems participating in the weeklong pilgrimage. The stakeholders identified in this initiative are 1-Government: leaders at national and local scale and interrelated institutions, 2-the Islam international community, 3-the design team and workforce, 4-the construction industry, 5-the wisdom keepers or Islamic scholars, Shaikh Ibn Uthaymeen et al. Stakeholder management is a gesture of accountability and responsibility to deliver the project development intent. There is even more expectation in Government led initiatives, wherein it is crucial that project management meets the needs and interests of different stakeholders. To do so necessitates planning with these different groups in mind and to test what fits best. The assessment of stakeholder needs in the Jamarat Bridge Revamp Project requires a tedious understanding of the relationship between a built structure design and how it affects crowd dynamics, and does a built structure ensure safety in intense and complex flows of people. But this is not as simple as it seems because the movement of pilgrims are within a given time frame of the ritual particulars, and the increases in worshipper volume should be accommodated in the continuance of Islam traditionalism. Working with a distinct culture, such as in this circumstance, requires a deeper understanding of norms, dynamics in public interactions, and other sensitivities before exchanges are initiated. There are qualities to learn beforehand engaging stakeholder approval. Lateral approaches in the conduct of coordination are not consistently appreciated within certain social structures. Too much equalisation between interest groups could impede on the project, or stem into

The word perfume

The word perfume Introduction: History of Perfume The word perfume itself is derived from the Latin per fume, which means â€Å"through smoke†. Due to the fact that the original use of aromatic materials was of burning incense, as an offering to the gods.1 Aromatic materials have been used for a variety of different purposes over the past thousand years. Perfumes during this era largely consisted of uncharacterized aromatic compounds.2 Ancient Egyptians used such fragrant materials in many different forms. While it wasnt until the Crusades that perfumery became more knowledgeable, due to the increase in trade of spices which was a known ingredient in perfumes.1 However it wasnt until the 19th century when alchemy became more popular that perfumes began to evolve and change into its current state. The past 100 years has seen the rise of many perfumes that extensively use synthetic chemicals. The first example of the modern perfume was in 1882, Fougere Royale created by Paul Parquet, composed of many synthetic compounds.1 Throughout the next few decades major advancements in the structural characterization of aromatic compounds (with the use of gas chromatography and mass spectroscopy2) led to the creation of synthetic materials. Perfume industries of late use large amounts of synthetic ingredients in the perfume production compared to natural sources. Statistically out of 3000 fragrance ingredients, less than 5% come from natural sources.1 Section 1: Production of Perfume The components of perfume that provide the fragrance can be produced/extracted in 2 major ways. As mentioned above until 100 years ago perfumes used natural sources for use of fragrant chemicals, since then the compounds are synthesised artificially in laboratories. Methods of both production types are mentioned below. Natural Perfume Ingredients Natural sources vary from plants (lavender, jasmine etc.), fruits (lemon, orange etc.), and animals (musk from deers, ambergris from whales). The components that contribute to the smell of the above sources are produced using methods that fall into 3 basic techniques. Expression: simplest of the 3, only used for citrus oils, involves squeezing and compression of the material to obtain oil.3 Distillation: used in manufacture and extraction of essential oils in plants, steam is utilised to help release aromatic molecules from the material. The oils co-distil with the steam, causing the water to be separated (using a Florentine flask) and discarded from the oils. However in some cases the water can be distributed as â€Å"floral waters†, as they may contain certain fragrant qualities.1 Solvent Extraction: the most important and frequently used in modern perfumery. Typical solvents consist of combinations of petroleum ether, acetone, hexane and ethyl acetate and various others. This technique produces a concrete (resinoid) which can then either be distilled into an essential oil or extracted using ethanol to produce an absolute.1 However ethanol extraction cannot be used on plant materials as they contain water, which can be absorbed by ethanol. Therefore a new technique known as the ‘Superficial Fluid extraction is used where the solvent used is Supercritical CO2(carbon dioxide in its fluid state). This process is more successful in providing fragrant compounds with odour, that more closely resembles that of its raw material.3 On the other hand its is a very expensive process, due to the pressure and temperature required to keep CO2 in its liquid state.1 Synthetic Perfume Ingredients As organic chemistry began to develop, the fragrant chemicals involved in perfume began to gradually become synthetic. The first perfume to utilise new synthetic materials is known to be the popular Chanel No5 in 1921. It used aliphatic aldehydes for the first, which helped to create a rich jasmine ‘note for the perfume. One major reason that the perfume industry use synthetic compounds over the natural is because of its expense. It is much cheaper to produce the materials synthetically than extracting it by natural means. Structurally almost all fragrant molecules have stereocenters, any point in a molecule where interchanging of any two groups leads to a stereoisomer. 7 Due to this it becomes difficult to synthesise the particular isomer required for fragrance. In 1991 however a scientist known as Paquette synthesised a steroisomer of Ambrox, which is known to be an amber odorant.2 The isomer is (-)-9-epi-Ambrox. This was made possible due to the use of a method known as oxy-Cope rearrangement2 to isolate a single isomer. Process: The active species, the bicyclic ketone is treated with dihydrofuranyl lithium, producing 2. This product is then reacted with phenylselenyl chloride, producing the compound 3. The removal of the phenyl selenium group providing the double bond required, and then followed by alkylation with methyl iodide and LDA. Sodium borohydride (NaBH4) is then used to reduce the ketone molecule into an alcohol. Catalyst palladium utilised to reduce double bonds. This product is then dehydrolated to produce the desired (-)-9-epi-Ambrox.2 The above example of chemical rearrangement is one of the many process is used in the formation of synthetic fragrances. Determining the fragrant materials of perfumes requires analysis of its chemistry. This is done by the use of gas chromatography and mass spectroscopy. The use of analytical chemistry is also evident in the synthesis of perfume. These aromatic compounds that have either been extracted or synthesised are eventually formulated with other ingredients to produce the end product, Perfume. Formulation of Perfume Once the perfume oils are collected, they will be ready to be blended together. There may be as many as 800 different ingredients and take several years to formulate a special scent.5 Once the scent is created alcohol is mixed with it, this can dilute the scent of the perfume. Alcohols also evaporate quickly which allows the scent (top notes) to be released at a faster rate. The alcohol used in perfumery is ethanol and is odourless.5 Alcohols used in perfumes is usually denatured so that they are not marketed as alcohol rather than perfumes. This process is known as Blending. Section 2: ‘Notes on Perfume The term â€Å"notes† in perfumery means smell. The whole concept behind perfume is its fragrance. Notes are a descriptive form of the many layers of fragrances found in perfume. Perfumes usually consist of three notes: Top Notes: are responsible for the initial smell of perfumes. They normally consist of small, light molecules that evaporate quickly (with the help of alcohol), the most volatile compounds. Heart Notes: the smell that sets after the quick evaporation of the top notes. Forms the main aroma (hence known as ‘heart) of the perfume, has the ability to last several hours. Base Notes: expectantly the scent that appears after the exit of the heart notes. These are made of heavy, large compounds which evaporate the slowest. The long lasting scents of the base notes are very rich and deep, helping to sustain the effect of the perfume.6 Section 3: Physical aspects of Perfume The main physical aspect of perfume is its colour. Perfumes that have colours are found to be more attractive to the buyer. However not all perfumes are coloured, this is because manufacturers add compounds, compounds that reflect certain colours in light, into the perfume. For example: Section 4: Allergies caused by Perfumes Breathing problems, asthma and contact dermatitis (an itchy and inflamed skin rash) are typical reactions to fragrances. These irritations are known to be caused by the various mixes of chemicals in the perfume. Examples of the many allergenic fragrances include chemicals such as amylcinnamic alcohol, anisyl alcohol, benzyl alcohol, benzyl salicylate, even natural products such as clove oil, nutmeg oil, odor of rose and cinnamon oil. These can result in rashes or swelling on surfaces of hands, arms and face.9 The addition of alcohol in perfumes only increases the allergies/irritation to the skin. To prevent alcohol allergies it is possible to manufacture perfumes with perfume oils4 instead. Perfume oils other than preventing alcohol allergies can be less expensive to produce and in terms of fragrances allows the scent to last longer. To make perfume oil, carrier oil is required to substitute the alcohol and the water. Jojoba is an example of carrier oil, as it has a very long shelf life, no scent of its own and it is not greasy.4 Conclusive Summary: As the above discussion suggests, the manufacturing process of perfumes uses a vast array of chemistry.
