Essay The Various Renewable and Non- Renewable Energy Sources
Electricity is a vital service a majority of the world uses on a daily basis. If it were to be depleted, many of us would not know what to do. Thankfully, however, not all sources of energy are non-renewable (although the renewable sources do have their downsides). Some sources are more prevalent in certain areas, while they may be extremely scarce in others; on the contrary, some sources are found all over the world, but only in trace amounts. The world around us uses many different types of electrical energy and a variety of sources from which that energy may be extracted. Solar power, biomass, wind, oil, gas and coal energy all have their positive and negative effects on the environment, animals and human beings. Without them, the†¦show more content†¦Transistors act as switches or amplifiers in an electrical appliance through the use of small-voltage-directed currents. Once the photo-resistor detects no light reaching the solar panel, it will allow the current to flow an d complete the circuit, allowing the bulb to light up. In order to use solar power predominantly, however – whether it is in a household or a whole country – it must be continually present. In many parts of the world, it is not so; cloudy weather is fairly common in most inhabited areas and in some, the sun barely shines. To set aside an area for solar panels alone would disrupt the ecosystem there, as well. In sum, solar energy is easy to harness and extremely available in certain areas, but it can pose difficult challenges at times. Biomass is the energy found in most organic materials. For example, many plants including trees, straw and vegetables carry energy converted from the sun. When plants employ the process of photosynthesis to make their food (CO2 (g) + H20 (l) + energy from the sun– O2 + C6H12O6(s )+ H2O (g)), some of the energy is stored within the plants rather than being given off as heat. It is constantly renewable, as the goal of many living things is to reproduce before expiring. The most common way of using biomass is burning wood and other plants to release thermal and light energy, then in turn using those to power PV cells or thermocouples, which convert thermal energy intoShow MoreRelatedSolar Energy : The Ultimate Renewable Resource Manish Kumar1264 Words  | 6 PagesSOLAR ENERGY IS THE ULTIMATE RENEWABLE RESOURCE                                           Manish Kumar (EE B.Tech)                                                                                                               Universal Institute of Technology, Garhi (Hisar)                                                                                                                manishboora13@gmail.com   Abst ract-The energy availability is essentially needed for all living beings in life .TheRead MoreRenewable And Non Renewable Sources Essay1604 Words  | 7 PagesSimply put, energy is â€Å"a driving force behind all socio-economic activities†(Wesseh, Lin, 2016).

Descriptive Essay Valuing Identity - 3121 Words
Bestolarides 1 Paul Bestolarides Professor Stark HRS 296: Global Histories 27 February 2015 Valuing Identity I could recollect a nostalgic instance in life about a traveling experience, but upon arriving to the city of Amman in the Middle- East, no experience was evermore instilled into the intellect of my ignorant eighteen- year- old, self. Immediately, I could recognize the solemnity of organization; the formal wear between people, the newly creative technology for consumer purposes and the religious reminders echoing through the highest towers of the Mosques. The experience was unlike any from the United States. These perceptions informed me that I was living in some kind of utopian society.†¦show more content†¦Appiah, Huntington and Fukuyama’s text surround the history and reality of some the major concerns, about the fall of ideologies, resulting in a Western liberalism. But not only do these texts inform us about, i.e., how to live, what will happen, but how we can improve our lives, to compliment another’s, who are not from our specific locale. Bestolarides 2 Each of us belongs to different cultures, yet we hold some of the same universal values. It is essential to examine each author’s noted significance. In Appiah’s ‘Cosmopolitinism,’ he implies that some of the innate universal values that each individual hold, can be expressed through art, mathematics and moral values. These values manifest into a universal identity according to Appiah, [pg. 94]. â€Å"They are present in every large enough group of our species; in particular, they are the statistical norm in every society,†[pg. 95, paragraph 1]. But, to Appiah, humanity is not an identity at all. Instead, it is a collection of shared interests. Appiah concludes Chapter 6 with this particular philosophy: You can make a stranger into a common human if you discover each other’s shared interests. And in keeping this shared interest, it is beneficial in sustaining a culture. By examining a culture of any kind, a connection can be made, concerning how cultures can make up an identity. His seminal book Cosmopolitanism, is a moral manifesto, for a world where identity has become a weapon and where

Operations Management for Changi Airport- MyAssignmenthelp.com
Question: Discuss about theOperations Management for Changi Airport. Answer: Value Chain for the Passengers Operations The Changi Airport, Singapore is a busy airport with passengers visiting the airport from all over the world. The operations of the transfer of the inbound and outbound passengers have a key role to play. The value chain for the operations of the passengers of the Changi Airport at the Terminals 1, 2, 3 and possible 4, includes a series of operations (Boonekamp Burghouwt, 2017). As the passengers arrive at the terminals, the boarding passes are verified long with their passports. After checking the validity of the boarding passes and the passengers are directed to the lounge or the waiting area (Goetz, 2015). In order to ensure that the value chain is efficient and the comforts of the passengers are not compromised, attendants are allocated. The waiting area has a lot of refreshment options along with duty free shops. The passengers, while waiting are able to chose from a wide variety of food, along with shopping from the duty free shops. Moreover, for further entertainment, the pas sengers might avail the lounge access, where free buffet is available for the passengers. Other entertaining and leisure activities such as television, swimming pools, gyms, indoor gaming options, Internet gaming options are also available in the lounges (Jarach, 2017). The passengers travelling in the economic class have to pay to access the lounge, while the passengers travelling in the business class have free access to the lounge, and access to all the facilities available. This creates an effective value chain and the passengers are satisfied and impressed. Moreover, waiting for the flights remain boring no more and these attractions increases the footfall of people at the Changi Airport. The pre transport and post transport of the passengers to and from the terminals adds to the value chain (Merkert Alexander, 2016). The passengers are transferred to and from the terminals in luxurious trains and hence the comfort and convenience of the passengers are given adequate importance. Thus, the value chain for the passengers operations of the Changi Airport is efficient enough thus giving the airport an international recognition. The foods that are served, along with the duty free stores that are available provide world-class products thus enhancing the value chain efficiency. Moreover, the passengers travelling at a regular basis are also given loyalty cards and offers such that they are able to access more facilities and get better services at a lower pri ce. Supply Chain for the Passengers Operations The supply chain for the passengers operations at the Changi Airport includes a series of stages, from the time when the passenger enters the Changi Airport, to the time the flight in which the passengers are boarded takes off. The supply chain for departing passengers are described below: Passenger arrives at the airport. A parking access is to be provided to the arriving passenger, such that the car in which the passenger arrives could be parked quickly, without creating congestion (Sien Singh, 2016). Once the car of the passenger is parked, the availability of the trolley to carry the luggage needs to be ensured. Arriving at the terminal, the waiting time of the passengers have to be reduced such that all the passengers can board their flight on time. The reduction in the waiting time is possible only if the number of staffs and the efficiency of the staffs are enhanced. The aged and the disabled passengers are directed to a special queue, where the waiting time is minimum. The ease of finding the way to the particular terminal has to be ensured. In order to do so, appropriate displays are to be put up, along with display screens to direct the passengers to the right terminals. Elevators and walk elevators need to be provided by the airport such that the passengers find it easier to travel to their destined terminal. Facilities such as ATMs, shopping plazas, lounges and restaurants are to be provided for the ease of the passengers (Tretheway Markhvida, 2014). The ease of accessibility of the washrooms need to be ensured with clear indications of the position of the washrooms. At the security check point, the passengers need to be assisted and the waiting time should be minimised. The courtesy of the staffs are also an essential part of the process. Finally, the passengers are send for the immigration clearance after which the passengers are ready to board the flight. Thus, the supply chain and its efficiency has a key role to play in ensuring that the passengers are satisfied with the services provided. References Boonekamp, T., Burghouwt, G. (2017).
