How to use a Rubber in Mobile Phones - Essay Example This paper focuses on mobile technology. Some of the factors to consider when choosing materials for developing a mobile device will include, weight, girth, flexibility of the material and its fitness for the intended purpose. The mobile device market has over the past years evolved to unimaginable extents. There has been the development of space age smartphones with unimaginable capabilities and processing speeds. There has also been vast improvement in the display of such devices in both clarity and size. Many mobile devices have been unveiled by different manufacturers such as Nokia, Samsung, HTC, Apple, Motorola and many more competing for the consumers available. One thing that has been an issue is the safety of such expensive devices when they get to fall or submerge in water. To solve this problem, we focus on Nokia’s N9 and the use of rubber by Nokia to act as a protector to this flagship device. Then Nokia n9 uses an 8 megapixel rear camera that is used for photography. The type of lenses used is Carl Zeiss by Nokia with autofocus and image stabilization property. This camera also comes with a dual led flash light to assist in photography in dark conditions. It is one of the most crucial parts of the phone. The battery in the Nokia n9 is what sustains the life in it. It a lithium ion battery that is internal to the mobile phone. It has a large capacity so that it can power up the large display and the processor together with other auxiliary components. This is the N9’s AMOLED gorilla glass curved screen that covers the whole of the N9 front face. This is a touch screen used for both input and output in this system. It not delicate as such since it is curved hence can resist a little bit of damage. The N9 case is made of polycarbonate that is well brushed.

Namaste solar case study - Dissertation Example If the current scenario continues the oil reserves will soon be exhausted. Moreover use of oil leads to flow of precious foreign reserves from the developing countries and sheds a negative impact on the balance of payments of an economy apart from causing environmental hazards. With increasing awareness the use of bio-fuel is increasing. Environmentalists opine that use of bio-fuel sheds less effect on the climate and decision makers reveal use of bio-fuel can lessen the pressure on balance of payments. The primary and major emission gas for Greenhouse Gases is carbon dioxide (CO2). When the carbon dioxide goes into atmosphere and changes the weather conditions, the bio-diversity will decrease through increase in temperature. 1.2 Types of energy 1.2.1 Renewable energy The introduction of bio-fuels will increase the prices of foods and also reduces the availability of food. The shortage of supply of food can be countered by increasing the productivity of agriculture. The bio-fuels obt ained from food crops are economically viable when the food prices are low and the prices of fuel are high. The globe witnessed high energy prices in 2000. The bio-fuel was made profitable with high energy prices coupled with low prices of food. The rise in prices of corn can lead to big losses for the processors of corn bio-fuels. The emerging markets of bio-fuels will provide new markets for forest resources and the net benefits will get accrued the local economies. The industries selling forest products are also likely to get benefitted. The negative effects will vary across regions. Bio-fuels can be utilized in electricity generation in the decades to come. The global industry of bio-power will bring enhanced prospects to the economy filled with natural resources. China, India, Latin America and Africa are the major gainers from the energy saved by improved cook stoves. China has saved 40 to 59 percent of its energy consumption by bringing 20 to 30 percent improvements in fuel e fficiency. Energy is needed for poverty alleviation in the developing countries. However, with the rise in income levels, a shift in trend of preferences has been noticed. Modernization of agriculture will provide spaces for biomass energy production (Zilberman, Rajagopal, Sexton, Hochman, 2008). 1.2.2 Non renewable energy The total green house emitted by some individual, product or organizations is termed as carbon footprint. It is difficult to calculate the total amount of carbon footprint due to unavailability of data. Carbon accounting is used to assess the GHG emissions of a nation or organization. Population, carbon intensity in the economy and economic output are the main influences behind carbon footprint. In order to decrease the level of carbon footprints, these agents are the target of individuals. If the size of the carbon footprints is known, strategies can be taken with the aim to reduce it with
