Flow of a Free Air Jet Laboratory Exercise

mix of a Free transport Jet Laboratory ExerciseAn investigation into the structure of a free breeze fount and how its f number is distributed during interaction with its surroundingsSummaryAir gushs have leave aloned the basis for thousand propulsion mechanisms, commonly usaged to provide exploit in kB engines, spacecraft and even particular marine animals. In communicatewave, it is important to handbill an aircrafts velocity, altitude and Mach number in order to proctor performance and determine line of businesss of improvement. In this experiment, a pitot-static subway system system was set up along the axis of a free air jet, and the local velocity of the air jet was deliberate and recorded using measurements from an inclined manometer as the pitot- tobacco pipe was displaced in both the horizontal and vertical planes. The experimental and theoretical results highlighted the same trends, confirming the expectation that as decreased (due to increase displacement) , local velocity, , also decreased. A divergence angle of 10.1 was measured, and the al-Quran menstruation rate varied between 0.0149 m3s-1 and 0.049 m3s-1. establishmentAn air jet is a prig or tube from which a directed pressurised jet of air is emitted. (1) These have provided the basis for jet propulsion producing a thrust in the opposite direction of the jet as demonstrated through Newtons third law. Airs jets are commonly used to provide movement in jet engines and spacecraft, and even certain marine animals have evolved to rely on jet propulsion mechanisms. (2) There are two main types of jet impinging and free. While an impinging jet is directed towards a surface, this experiment is concerned with the interactions of a free, submerged air jet, where the jet is discharged into an ambient gas of similar physical properties. (3)A pitot tube is a embrace measurement instrument used to measure peregrine flow velocity. (4) This is done by converting the kinetic energy of the flow into potential energy (5). Pitot-static systems, consisting of a pitot tube, a static port and the necessary measuring instruments (6), are often used in aviation to determine an aircrafts velocity, altitude and Mach number, as well as having nautical applications in the calculation of boat and vessel speeds. (7)Theory3.1 amphetamineA pitot static tube measures two separate pressures the stagnation pressure,, and the static pressure, (8) Bernoullis equation states that the total stagnation pressure is equal to the sum of the static pressure and the dynamic pressure, . The dynamic pressure is comparative to the density of the concerned medium, , and the square of the local velocity, v, such that (equation 1)If the pressure difference between the stagnation pressure and static pressure is applied to shift the water level of a manometer, equilibrium is achieved when (equation 2)Therefore, by combining equation 1 and equation 2, and assuming = 1.225 kgm-3 and = 1000 kgm-3 , the local velocity in ms-1 quarter then be calculated through the relationship (equation 3)3.2 Flow RateThe volume flow rate leaving the nozzle of a circular air jet, can be considered equal to exit velocity, , multiplied by nozzle surface area, A. (9) This relationship is represented through the equation (equation 4)Beyond the nozzle exit, the velocity cannot be considered constant at all vertical points in the jet therefore, it is necessary to integrate to find the volume flow rate.The expanded profile of the air jet can be considered circular, consisting of a series of annuli areas containing an air flow rate equal to for each respective measured value of velocity and calculated area. This is represented visually in figure 1 below.Recalling the area of an annulus as, where is the radius along the mid-point of the annulus, and considering the asymmetrical profile of the final jet requires separate measurements in each hemisphere, the total volume flow rate can be calculated through (equation 5)Here, is the local velocity at the required radius and is the area of half an annulus, where is the radius at which the velocity was measured.MethodApparatusNozzle of diameter 30mm, to create the uniform circular jet of air to be measured.Pitot-static tube system, consisting of a pitot-tube, static tube and axile scales,to collect the air from the nozzle and carry it to the manometer.Manometer, inclined at an angle, , which holds the liquid and allows for its movement depending on the pressure sheer from the pitot-static tube system.A zero(a), to locate the starting point at which measurements of the wandering distance along the manometer will be taken from.A ruler, to manually measure the distance travelled by the liquid along the manometer, .ProcedureThe zero was adjusted along the manometer to indicate the point at which further measurements with the ruler would be taken from and the pitot-static tube was moved along the apparatus to the origin, at the c entre of the nozzle, where the coordinates corresponded to (0, 0). The air jet was turned on and, after allowing sufficient time to sensitive up, the distance the liquid had moved along the manometer, was measured, using the ruler, and recorded. The tube was then moved along the centreline crossways a series of predetermined distances away from the air jet ( rule Appendix A) up to 500mm the point (500,0) and was again measured and recorded at each interval.The pitot-static tube was then returned to sit 60mm away from the air jet and lowered to a vertical height of -28mm from the origin where was again measured and recorded. Maintaining an axial distance of 60mm, the pitot-static tube was then raised in increments of 4mm up to a maximum height of 28mm and the distance, , measured for each step. This experiment was then repeated at axial distances of 180mm and 300mm, through chains of -50mm to 50mm and -60mm to 60mm respectively, using increments of 5mm in both.Results5.1 Velo city ProfilesThe recorded distances,, for the troika vertical experiments, were then converted into vertical distances, h in this experiment, = 13. The velocities at each height were then calculated using equation 3 and charts of velocity against height for all three axial distances were drawn as shown in figures 3a, 3b and 3c below.5.2 Plan ViewThe divergence angle can be calculated by forming a triangle between the edge of the jet and a line perpendicular to the nozzle boundary see figure 4. For this experiment5.3 Centreline Velocity DistributionThe recorded distances, , for the centreline experiment were converted into vertical distances, h, using = 13. The axial distance, x, was then divided by the nozzle diameter, D = 30mm, and a graph of velocity against was plotted, as seen below in figure 5.5.4 Volume Flow RateAssuming is constant at the edge of the nozzle, the exit volume flow rate can be calculated through equation 4 m3s-1Beyond the nozzle exit, values for, the annul us width, and , the come oner radius, were required to calculate volume flow rate. The values for were 4mm at an axial distance of 60mm, and 5mm at axial distances of 180mm and 300mm, and values for corresponded to the radial-ply tire distances these can be gear up in Appendices B, C and D.victimization equation 5, the volume flow rates were found at x = 2D, x = 6D and x = 10D respectively, and the results displayed through table 1.Axial Distance (mm)Volume Flow Rate (m3s-1)600.019251800.0344753000.048705A graph of volume flow rate against axial distance was then plotted for comparison see figure 6 below.6.1 Structure of the Air JetAn air jet is comprised of three important regions the core, the salmagundi region and the edge or boundary. Within the core, the velocity does not vary significantly from the nozzle exit speed. From the measurements in this experiment, this region exists up to around 180mm along the centreline (see figure 5). Outside of the core, illustrated in figu re 4, the intermixture region is encountered. Throughout this region, the local velocity,, is less than the exit velocity, , due to the reaction of the air jet with the ambient fluid. The edge or boundary of the jet represents the radial distance at which the local velocity is equal to zero at each centreline distance. The edge of the jet increases linearly at a rate mutually beneficial on the divergence angle, measured to be 10.1 in this experiment. This is similar to the universal value for the divergence of a jet of 11.8, which is independent of nozzle diameter, discharge speed or the medium involved. (10)6.2 Diameter of the Air JetFrom the plan view illustrated in figure 4, it can clearly be seen that the air jet spreads out as axial distance increases. This occurs as a consequence of the significant velocity difference between the jet and the ambient fluid, which creates a highly impermanent shear layer at the edge of the jet. This shear layer is subject to large variance in local velocities, generating strong turbulent fluctuations which subsequently get on the ambient fluid into the path of the jet, increasing the mixing of the two fluids. As a consequence of both the turbulent fluctuations and the entrainment of the ambient fluid, the shear layer continues to be pushed outwards as the jet flows downstream. (11)6.3 Centreline Volume DistributionFigure 5, above, clearly illustrates that up to a value of = 6, the velocity along the centreline varies very little, with a range of 0.833 ms-1. This region is known as the core, where. The only source of momentum when the jet exits the nozzle is from the jet itself, as the surrounding fluid is at rest. The absence of external forces acting on the jet suggests that the centreline velocity will remain constant as distance increases. (11) Beyond an axial distance of 180mm, the velocity follows an inversely proportional relationship with distance, decreasing at a rate of (where k is an unknown constant). Thi s occurs when the core of the jet interacts with entrained ambient fluid caused by significant velocity fluctuations at the edge of the jet, decreasing the velocity of the fluid as discussed in section 5.2. Due to the interaction between two different fluid flows, the region in which this occurs is referred to as the mixing region.6.4 Volume Flow RateFigure 6 suggests that volume flow rate increases linearly with axial distance, rising from 0.015m3s-1 at the nozzle exit to 0.049m3s-1 at an axial distance of 300mm. From section 4.4, it is known that the volume flow rate is a function of the jet area and local velocities across the diameter. Due to conservation of momentum, it is expected that as the area increases, the velocity decreases such that the volume flow rate remains constant across all axial distances. However, the increase in volumetric flow is a result of entrainment of the stationary surrounding fluid. The turbulent flow caused by the velocity fluctuations in the shear l ayers contributes to an increased local velocity across the diameter of the jet, increasing volume flow rate.6.5 Experimental Errors and UncertaintiesAlthough this experiment has successfully demonstrated the characteristics of a free air jet as highlighted in this discussion section, numerous errors and uncertainties were still encountered throughout the experiment which could have had a potentially significant effect on the results obtained. One of the or so common sources of uncertainty was the use of a ruler to measure the distance of the fluid along the manometer. This combined human error, due to the estimation of both the zero position and the final position of the fluid meniscus with systematic error, as a consequence of the ruler measuring with an uncertainty of 1mm and therefore, accurate measurements for were not obtained. Similarly, the fixture of the necessary axial and radial positions for the pitot-tube were subject to a similar human error. The fluid in the manome ter also contained several air bubbles prior to the experiment this is a systematic error as it would subsequently affect every manometer distance reading. Therefore, it is possible that the results obtained for could consistently higher than expected due to the presence of these air bubbles in the fluid. The final significant error involved in this experiment was the random error associated with the changing position of the static tube. For a set axial and radial positioning of the pitot-static tube, changing the height and geometry of the static tube caused the manometer reading to alter slightly as well. Although efforts were made to maintain the location of this tube, there is still the chess opening it could have caused sporadic errors in the results.To conclude, the experiment outlined in this report was successful in demonstrating the interactions of a free air jet with an ambient fluid and, subsequently, the effects of the displacement of the pitot-tube on the local veloci ty along the centreline and throughout the mixing region. The decreasing local velocity as displacement increased was found to be a result of turbulent fluctuations causing entrainment of ambient fluid into the path of the jet.In the experiment, the maximum velocity was found to be around 20ms-1 for a distance of 180mm along the centreline of the jet and the divergence angle was calculated to be 10.1. These results were useful in introducing the basic structure of an air jet, which comprises of three main regions the core, the mixing region, and the edge. The slight discrepancy between the measured divergence angle and the universal angle of 11.8 (9) can be considered due to the inaccuracy in measuring the position of the fluid meniscus in the manometer using a ruler, producing potentially unreliable results.The findings from this experiment are statistically insignificant due to the nature of the apparatus used and the unhomogeneous possible sources of error, both systematic, due to air bubbles present in the manometer fluid, and human, arising from the use of a ruler for distance measurements. However, the experiment was useful in demonstrating the interactions of an air jet with its surroundings, as well as introducing the concept of internal structures within a free air jet.1Oxford Dictionaries, Air Jet, Online. operable https//en.oxforddictionaries.com/definition/air_jet.

The Impact Of Social Media Marketing Essay

The tell apart to Of affectionate Media Marketing EssayThis assignment discussing just almost the impact of tender media on the way disdaines argon conducted today in terms of technological, economical, political and cultural exchanges brought whateverwhat by these form of new-fashi peerlessd communication. As we know this modern communication program giving impact to businesses today. We dont pee-pee each control to genial media beca use this platform giving users drop outdom to express their opinions, experiences or boththing that they wants. kindly media providing bombastic opportunity to organization to build remedy relation with clients and providing real unmatchable to one communication. clients be now become much particular most with whom and from where they are buying products or services. One of the main reason wherefore businesses must use mixer media is because their competition employ this platform unremarkable as selling strategy. Customers and future clients in same manner use that.Case study on giant restaurant McDonalds showing that horizontal big companies likewise un fitting to control the strength of loving media.Wildfire ROI Survey 2011 review shows that, marketers admits loving media lot them to increase brand awareness and increasing customer relation. rail linees that directly interacting with customers should use brotherly media to increase their tax and increase the brand awareness. legion(predicate) a(prenominal) organizations now start development internal neighborly meshwork which connects their employees all around the world. For pillow slip, Red Robin Gourmet Burgers Restaurants tolerate more than then 460 outlets in America using internal well-disposed network to make sure daily operation getting much better and they become one of the famous restaurant in America. The arrive one world retailer who attain more then 2.2 million employees in 2012, Wal-Mart using social media plat form to streamline supply chains and manage the stocks and inventories more efficiently to reduce the product price.Any products related to social media also helping boost the world economy. Products similar laptops, iPads, iPhones, headphone, head hang and so on which used by customers to access social media received very high demand.Thousands of companies worldwide involved in offering social media services offers thousands of jobs opportunity. virtually Fail Stories of Businesses when Using Social Media is Netflix where they are one of the top internet subscription service for watching movies and TV programs from any countries lost 800,000 customers because avoid listening to customers feedback form social media.Example of Success Companies because of Social Media is KLM Royal Dutch Airlines where successfully enjoy with meet and seat entreat which let the passengers choose the seatmate before board the plane.As a conclusion, Social media promising a lot of opportunities and challenges, so organization must prepare themselves to go about this.What is Social Media?Andreas Kaplan and Michael Haenlein describe social media as a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0 and that allow the creation and exchange of user-generated content.Social Media contains two words. The first one is Social which means interaction, overlap and so on. An different word is Media where to say that social media is a medium for publication.Social media contains a lot of tools and applications which let the users express their opinion, publish articles, share videos and so on easily.Social Media LandscapeThe chart below shows the social media network landscape. There have a lot of different tools and services which allow users to do almost anything that they want.For publishing articles, opinions, news and so on there have blogs, wikis and citizen journalism portals. chitter is for Micro publication. There ha ve thousands of website that allow users to share videos, pictures, links, music, slideshows and product reviews. Websites like YouTube.com, FlickR and so on are some of the popular sites.To make discussion and sharing ideas or even making complaint about any companies, there have forums, video forums, instant messaging and VoIP. Social Media also allow us to watch world live tv programs or even live football from anywhere in the world. There also have platforms for virtual words, social gaming and MMO.The most popular network on internet is Social Networks like Facebook, MySpace, LinkedIn and so on that connecting anybody from anywhere. gibe to Edison Re behavior Survey in 2012 (the still providers of exit polling development for ABC, CNN, CBS, Fox, NBC, The AP and most of newspapers worldwide) says that, more then half Ameri kindle has created profile in any Social Networking websites.Edison Re search Survey in 2012 also shows that nearly two thirds of social networkers are us ing social sites daily.Social Media HistorySocial Media history began in 1969 when CompuServe Company offers internet services for public using dial-up technology in United States. Then in 1979 Usenet become first bulletin board which connects Duke University and University of North Carolina. The development process continuously contemptible until Tripod introduced online community for college students and young adults in 1992. In 1997 there have more then one million sites on the internet including social media sites like AOL flashgun Messenger. Frindster become biggest social networking site in 2002 with more then 3 million users. In 2003 Myspace, Frindster clone site launched and LinkedIn also launched their business-oriented social networking site for professionals. In 2004 Facebook started their operation which offers networking opportunity for Harvard College. YouTube come to the world in 2005 and bring excitements to the world with video sharing features. In 2011 social m edia locoweed be accessed from anywhere in the world and become one of the important thing in our life. Thousands of sites offers social media services in 2012 and all this sites very flexible and atomic number 50 be accessed finished many different devices. Companies are now forced to use social media to make sure their brand of all time in customers mind.Social Media InfluenceAccording to Sir Andrew Likierman, London Business School Dean, social media has completely disrupted the way businesses assess their coifance. This statement is completely true because social media not biger an survival but is a must oddly companies that dealing straightly with customers. Some business discharge completely avoid thinking about social media like wholesalers because they unspoiled dealing with another business. Since social media become more power, organization facing difficulties to measure their performance. They must have specific strategy for social media or even companies could h ave one special unit that handle feedbacks and receipts from user. Any ban feedbacks should grab attention and they have to discuss on how to fight down with any prejudicial comments. Any negative response from customers exit be there on net forever. No way to remove that and because of that, companies that avoid think about social media result fall away some customers.Customers are now become more particular about with whom and from where they are buying products or services. They willing to make online search before making any purchase ratiocination especially for expensive items. Since internet is now more conveniently searchable through smart phones, customer can make search in just a minutes. Thats why companies must have social media presence and put some attention to manage customer response and try to convincing them that the business is reputable and trusted. Social media providing big opportunity to organization to build better relation with clients and providing r eal one to one communication. There have no better advertising then word of mouth. Satisfied customers surely will share to their friends in their social network about their experiences with a particular confederation. If one person shares their experience to his 400 Facebook friends, and that friends spread that news to their friends, the information moves extremely fast. If a video uploaded in YouTube with attracting title like Think Twice before you eat XXX, this video surely will grab thousands or even millions of social medial users. With Share function purchasable almost in any site, in just a second we can share anything to social media community.One of the main reason that we must use social media is because our competition using that daily as selling strategy. If we not use mean we loosing customers. Emarketer says in 2011, the Facebook advertising revenue estimated at 3.8 billion clam and can increase to 5.2 billion dollar in 2012. What does it mean?, this numbers show s that a lot of businesses using social media to make advertising. A lot of businesses have social media networks account. As a go out, competitors are forced to make online presence. They have no option, make appearance in social media or you will lose customers.Another big reason why a business should using social media because their customers and future customers using it. A lot of large number have at lease one social media account like Facebook, YouTube and so on. A business should present their brand where customers are. Traditionally we can see people able shops at conference places like in shopping mall and so on. The same case here where a business should present in crowd place like social media. Million of people using that every day. You didnt show mean, the competitor getting stronger.According to McKinsey, organization that using social media able to increase 50 percent customers satisfaction. They also able to catch 48 percent in business lead and the most importan t is, their profit increase 24 percent.Case Study (McDonalds)I would like to discuss about, what are the impacts of Social Media to one of the worlds popular fast food giant company McDonalds. If we search the word McDonalds on YouTube.com (one of the top video sharing site), there have 124,000 results. Among this results we can found that, thousand of results that showing bad thing about McDonalds. Some of the video titles areVideo with title McDonalds horror got more then 4.2 million views with 8,859 likes. Hundred of the viewers commented on this video and one of the comment is I think I dont want to eat french fries from McD again which got more then one thousand likes. This video showing about McDonalds foods and why some of their food takes long time to spoil.This is how now days people using social media to express their opinions and sharing bad thing about any brands. They are now having power which can influence other people behaviors. People who watching this video then su rely with spread this to their friends, relations and so on. This is real challenge to McDonalds and most of companies.Some competitor also may misuse social media to spreading bad thing about their competitors company. Any people can upload videos showing bad thing about their competitors company and they also may set specific campaign to putting them down. Nobody can damp this kind of behaviors and activities.As response, I see McDonalds showing some effort to explain questions that asked by viewers. McDonalds uploaded some response video. One of the video titles is stern the scenes at a McDonalds photo shoot (with 7 million views and more then 17,000 likes) which explains roots to questions asked by viewers. McDonalds realized the impact of videos uploaded by their customers to their business. If McDonalds didnt do anything as response to videos that showing bad things about them, surely this will impact their business performance and lost huge amount of customers. I found tha t McDonalds still didnt answer many more questions asked by customer through social media. They exclusively answer some of them and huge amount of videos still havent have any answer.In January 2012, McDonalds launched Twitter campaign with hashtag McDStories which let the customers to post nostalgic stories and their experiences with Happy Meals (one of the famous meal sold by McDonalds). As response, customers start to share bad stories about Happy Meals like customer service, food quality. One of their post is just got a terrible burger thats been there four hours. This is one of the fail campaign by McDonalds. As a lesson we must understand that social media offering big opportunity and big risk. Peoples perception and feedbacks is uncontrollable. Companies should have some contingency plan which can be used if any puzzle happens. Even worlds big giant restaurant also unable to control the social media.Measuring the Business Impact of Social Media (Wildfire ROI Survey 2011)Soc ial media is a long term strategy which falls under advertising and public relation investment. When social media combined with other marketing strategies, a particular brand will always at peoples mind.In November 2011, Wildfire (a division of Google) who is worlds largest social media marketing software providers, involved in ROI survey. This survey conducted to over 700 marketers from number of countries. This survey shows that, marketers admit social media helping them to increase brand awareness and increasing customer relations. Over 97% of marketers believes that social media marketing campaign increasing their business performance. As a long time strategy they also want to increase social media spending.This survey also shows that (see take place out 3), social media have power to growing brand awareness and able to increasing sales and partnerships. 41% marketers agreed that this media able to reducing cost that will result in revenue increase.94% respondents ranked Faceb ook as one of their biggest social marketing platform which giving more value to their campaign. Facebook giving more new customers, have high conversion rate and increased customers loyalty.As a summary of this survey we can see that social media changing how we doing business today. Businesses that directly interacting with customers should use social media to increase their revenue and increase the brand awareness. Day to day, social media getting more complex and businesses should start a set long term social media strategy. Big companies can use this media to improve their customer service because they can keep on eye on customers behaviors and react fast.The Impact of Social Media on the Way Businesses are Conducted TodayTechnological Impact some(prenominal) organizations now start using internal social network which connects their employees all around the world. For example, Red Robin Gourmet Burgers Restaurants have more then 460 outlets in America. They are using internal social network which look similar like Facebook to teach their employees and managers about the recipes and how to make them fast. They are no more using traditional ways like send out heap of books to each outlet. They are also no more waiting for feedback when store visit by headquarters and so on. Any problems that occur in any outlet get fast response from headquarters in just in few minutes. Everything becomes more easy and fast with internal social networks. Managers circulate with other managers in other outlet through chat or video conversation function. More exiting news is, they are creating burgers according to customers feedback in social media. As a result, Red Robin Gourmet Burgers becomes one of the famous restaurants in America.More and more companies are now using social media technology to speed up the business process and make sure every job done effectively. The number one world retailer who have more then 2.2 million employees in 2012, Wal-Mart using social me dia platform to streamline supply chains and manage the stocks and inventories more efficiently to reduce the product price. Many banks in America using social media to reduce cost for processing mortgages.SupeValu is one of the company who have number of supermarket chains in America using Yammer (enterprise social network software) to connect all 11,000 executives and store managers. They created 1000 groups in that network to discuss about challenges and discussing new ideas. All store managers are in one group where discussing problems and ideas. Another group of supervisors discussing problem related to their controls. This method is more cost effective rather then holding conflict where participated by all managers.According to McKinsey Co. Survey, they found that two-third of big companies in United States are now using web 2.0 application like internal social networks or blogs, 50% increase from year 2008. 90% of this companies admit that, this new communication way improv ed their operation and the process getting much faster.Eric Lesser, one of the Director at IBMs Institute for Business Value, said that social media make the communication between the worlds professionals with various skills to sharing ideas and solving problems easily.Social media technology lamentable extremely fast. This forcing company to have dynamic police squad which can learn new thing much faster. The software related to social media updated more regularly. The team must always ready anytime to facing new challenges. They must understand the most effective way to use social media which can bring darling result for the company. All this pushing companies to spend more and have specific budget.Social media increased the number of internet users worldwide. From 2008 to 2012 the world internet users increased by 30% according to BBC. This forced internet service providers to finding new ways to speedup the internet connection. This to make sure all business activities can be done much faster, cheaper and in more effective way. Now we can use 4G and Fiber Optic network to send out emails or any services just in second. Conversation thought Skype becomes more comfort without any interruption. More and more companies using latest technology for announce with other people. This is another good impact of social media.Economical ImpactSocial media helped businesses to create product which have high demand and according to customers unavoidably. Customer giving feedbacks which helped many companies to develop their products and services. Companies like Dell using ideas from customers to creating and improving their products. One of the example is created backlit keyboards which is more suitable when working on airplanes. Companies who creating products according to customers needs surely will help boost the economy because high demand to that products.Any products related to social media also helping boost the world economy. Products like laptops, iPads, iP hones, headphone, headset and so on which used by customers to access social media received very high demand. Meg Whitman who is CEO of HP, says that in the past 2 old age the sales for their laptops increased to more then 60%. The dramatic increase mainly because of impact of social media. More and more people using social media now and devices much(prenominal) as laptops receive high demand. Apple, Inc also admits that the sales for their hot product iPad received high demand as a result of social media.Social media also created job opportunities which can help the economy. Social media created thousands of jobs opportunities. Facebook has more then 2,000 employees, Twitter has 300 employees and Groupon employed more then 4,500 workers. This only some figures, there have thousands of companies worldwide involved in offering social media services which offer thousands of jobs opportunity. World economy increased and unemployment rate decreased. Business associated with facebook c reated 232,000 new job opportunity in Europe in 2012 according to the news published by CNN.Social media also created new sedulousness where many people able to make income online. Many people are now enjoying income from home and helped house wifes to generate income to helping their husband while take reverence of their children at home.Social media contributed many benefits to the economy but there also have some negative impact. Entertainment industry especially film industry affected by social media. Film nobles invest million of dollars to make movies. Thought social media sites like You Tube or any file sharing sites, any people can enjoy new movies at no cost. Even though industry players took some actions to reduce the impact, but they unable to stop this operation totally.Political ImpactMany country leaders are now encouraging people to use social media. One of the greatest example is Malaysian Prime Ministers, Najib Tun Razak. He has more then one million Facebook fa ns as well as Tweeter. He sharing a lot of information though his network about his daily activity and so on. As a result, many companies start using social media especially Facebook on their daily operation. Most of businesses in Malaysia have Facebook ID.If we go complicateder about the impact of social media in Malaysia, we can see Lynas Corporation upchuck. Lynas project is from Australian company Lynas Corporation. This company supplies rare earths for many businesses. Many opposition political parties in Malaysia shows protects against this project because they believe this project provide danger for local environments. Malaysian citizen shows protect against this project thought social media. Facebook and many other social networks filled with feedback about this project. As a result government took some action to explain to citizen about this project and promise to esteem back the existence of this project in Malaysia. This in one of the example showing clearly how social media impact governments decision and businesses.Cultural Exchanges ImpactSocial media highly impact most of business aspect. Now many businesses especially who have big number of employees start using internal social networking utilities which makes communication among them made simple. According to research made by Garner, in 2014 it assumed that more then 20 percent of businesses will use internal social networking utilities which will replace email communication now. With internal communication social network, any latest activities by company and so on will know by their employees much faster.Social media impact on human resource process from recruitment, development, career management, mentoring and so on.

He was also able to create characters with amazing individuality. Not only was his portrayal of the characters magnificent, just the symbolism he used which emphasized the story being told in the Last Supper. Lodovico Sforza chose Leonardo to create The Last Supper in the refectory of the Dominican Church of S. maria delle Grazie in Milan. The Abate of the S. Maria delle Grazie saw Leonardo work from morning until night on The Last Supper without eating. Although, there were times he would stop pictorial matter for days at a time or, he would work on a specific character for just a few moments and then resign to continue working on it later. He worked on it from 1495 thr u 1498 (Strauss, 27). Before Leonardo began painting the actual portrait, he put down a substance which was read to absorb the tempora and protect the tempora from the moisture on the wall. Unfortunately, the substance was proved unsuccessful, and by 1517 it began to deteriorate. In May 1556 a painter Giovanni Batista Armenini said that the painting was so staidly affected that nothing is visible but a mass of blots(Heydenreich, 18).

Baffled by this, steward talked to his doctor more or less the possibility that insulin must have been provoking the liver to produce cholesterol. His doctor, Bethea, another author of the book enthusiastically agreed. He sighted proof by explaining that insulin injections in diabetics tend to elevate cholesterol levels (Steward,Andrews, Bethea & Balart, 1995). Pledge of the Sugarbusters Diet.

By simply doing this, one can get slimmer and healthier simultaneously (Steward, 1995). One author, Dr. Balart, up to now states that the diet is easy.

Skins: A whole new look on everything :: Peter Dykstra Technology Essays

Skins A whole new look on everythingConcept Background Dykstras concepts of linear programming and modularity take on a whole new look. Peter Dykstra the father of linear programming suggested that anything that could be done in programming could be done with a combination of three basic procedures.Sequence- procedures performed in a linear order Decision- Expressions evaluated to determine between two routes of action. Repetition- The ability of a machine to perform an operation millions of generation a second. In order to clean up the commonly used spaghetti code of the times, Dykestra then proceeded to say that all code should be divided up into chunks related to a specific tasks called modules. The idea was that by abstracting these modules into black boxes that with well-defined input they would perform their tasks and generate predictable output. This would allow a programmer to not know anything about the modules he was using except what goes in and what comes out and still be able to use it. This modular thinking was eventually utilize to a graphical user interface interface, but is still not widely utilized. What is a skin?The term skin was first coined by a MP3 player called xxx-AMP. The GUI interface of a program is modulated and broken out from the program as explained in the previous paragraph and given the ability to be swapped with some other skins to change the entire appearance of the program. Would you ever guess them to be the exact same program? Would you ever guess the creators of these GUI interfaces were not paid to do it, or necessarily even professionals? My first introduction to a program that had some characteristics of skin like behavior was a shopping cart program with a Look and Feel Module that they had made public to great success. Groups of users would congregate around their site and support each other by swapping egotism generated custom modules and knowledge on how to create them. However it was far from eas y and involved more Perl than hypertext mark-up language or graphics work. How Does it work?Skins in the hypertext markup language world follow the same concept. A skin is a simple HTML page with special hooks for the CGI (or ASP, etc.) to connect to. For example in the HTML a variable that must be replaced with output from the CGI would be named $$varname This will cause the tag to be replaced with the CGI Perl variable $varname.

My grandmother chose to talk to me about my bulky grandmother, her mom, Esther P. Kelly. My gre at grandmother unceasingly attended church and would pray constantly during the day and night. My grandma was always curious as to why her mother was always praying. All through out childhood she would just watch my great grandma pray and do other religious acts of worship. When she became an adult she was finally fitting to ask my great grandma why it was that she prayed so much and how it came to be. My great grandmother answered by saying that she knows God can hear her prayers. She then give tongue to that while she prays she can no longer hear any outside interference or anybody else speak. She said it feels as if she is in a secluded sick place all by herself and that she has conversations with God.

She said that she would get so caught up in the moment that she would forget all about her ad hominem problems and the problems that awaited her outside the church doors.
