; (3) the power in the wind is proportional to the density of the air (Park, 1982). According to history, the practical use of wind power began with the Egyptians around 2800 BC when slaves were made to row overseas using sails which were further employed in lifting water and operating grain-grinding stones even to within the period when Persians built panemones or vertical-shaft windmills in 700 AD. Some other civilizations of the Middle East followed the same tradition whereas the Crusaders of the West are believed to have improved the windmill concept that led the Dutch to put up propeller-type windmills structured with horizontal shafts or axes of propulsion. Technical developments continued during the Middle Ages and comparative studies show aspects of similarity among windmills founded in British colonies, New England, and Holland which altogether bore significant impact in the construction of the widely known ‘American Farm Windmill’ which was invented by Daniel Halliday who, in the mid-19th century, thought of creating a multi-bladed (Panemone Bladed Rotor Wind Energy Harvester with 8 Airfoils) windmill. At the turn of the century, wind-produced electricity as well as wind-charger technology became popular, especially to the farmers of the Great Plains who necessitated up to 1,000 Watts of DC-power in their mechanically run farming tasks. Eventually, a number of countries in Europe were inspired to create wind generators of enormous size and both the French and the Germans attempted to conduct feasibility experimentation on 100-kW and 300-kW wind generator units in the 50s and the 60s. Through the years, the continuous process of harnessing wind power made possible not only D. Halliday’s multi-bladed craft but even the succeeding advancements in the iron water-pump industry which heightened the demand for wind-powered deep well pumps in the past. While the energy derived from the wind had been discovered with other chief potentials as in heating houses and barns, running sawmills and washing machines, several Midwest farmers who already possessed gasoline or kerosene generators to charge batteries still sought the aid of wind power in minimizing troubles with wear-and-tear generators and in reducing costs of fuels used. Such capacities, however, depend upon the quantities of wind power in acquisition. In his findings, P.C. Putnam illustrates a method to approximate the amount of power which can be extracted from the wind and the means to locate wind power with considerations to the periodic fluctuations in wind power as well as its reliability and short-term predictability. The author regards the concepts of kinetics hereafter necessarily pointing out that, like the kinetic energy of any particle, the kinetic energy of the wind may be computed via half of its mass multiplied by the square of the wind velocity and in terms of the volume V of air passing over an area A per unit time, the wind’s kinetic energy equals the product between wind density and (1/2)*AV 3. This is nevertheless
Wind Power (A Literature Review) In the study of wind power, it is essential to note that several factors affect the conversion of wind energy and the advantages of utilizing wind power out of the useful energy form generated may vary depending upon the requirements of different systems of function it is intended for…
There may also be cases of dismissals, resignations and retirements that will all call for the need to recruit and employ new workers. Even though recruitment and selection are one of the very usual and inevitable corporate practices, it is very important to attend to them with great caution and in by following good recruitment and selection processes that would ensure the company does not suffer the consequences of poor recruitment.
Hence, in this regard, both the private and the public sector have devoted considerable attention to the notion of customer satisfaction, which is a rudimentary basic in the customer-company relationship. Naturally, in order to increase the awareness about this concept, administrators have increasingly encouraged their staff to gain knowledge by studying and researching on this phenomenon of customer satisfaction for the welfare and growth of the organization.
Over the years, the landscape and the modus operandi of the business organizations have changed. This change has affected the job descriptions of the managers also. Now, managers are not treated as just employees with power; rather, they are treated as entrepreneurs with responsibilities.
Generally speaking, online businesses provide a number of considerable benefits to business owners, as well as to customers. Online retailers are able to increase customer trust through efficient response and better customer relationship management (Hoffman, Novak & Peralta 1999, p.
In China, there are many types of informal financers such as, Rotating Savings and Credit Associations (lending cooperatives formed by members of the society) like, bahui, hehui and yaohui, private lending individuals, lending enterprises and pawn brokers, who extend credit in exchange of non-traditional collaterals such as, jewellery and personal belongings.
Rather they are treated as entrepreneur’s wit responsibilities. The management as well as the juniors or subordinates look up to the mangers as leaders. The managers are not only expected to perform their tasks but also are
These steps and rules were as highlighted as follows.
That seems obvious enough, but a lot of people take it personally when they don’t hear back from someone right away. Resist the urge to get upset or mad, and never
be commercially viable, this form of energy has increasingly become popular in the twenty-first century, with many countries choosing to adopt it (Cradden, Harrison and Chick, 2012). One of the reasons for increasing support for wind power has been that it is clean renewable
More advanced methods of energy harvesting involve using microwave, magnetic resonant frequency and vibration energy. The motivation of RF energy harvesting is derived from the increasing need for energy recycling as it is
