Growing Trends of the Mobile Phone Industry

Written by Jo Wintour

The ever-changing mobile communications industry is again transforming consumer perception of telephony on-the-move. We’ve come a long way sincerepparttar 80’s "brick like" model that gave usrepparttar 147256 freedom to move away from dingy payphones. In fact, mobile phones today serve a completely new purpose. No longer is it solely aboutrepparttar 147257 need to contact a friend, colleague or family member at any time or place. What reaches out torepparttar 147258 majority of consumers today isrepparttar 147259 uniqueness of a handset; as mobile technology becomes fashion accessory. Constant advancements in technologies ensure we’re spoilt for choice, withrepparttar 147260 capacity to personalise almost every aspect of a mobile phone.

Consumers have been groomed to demand an increasingly high standard of functionality in their mobile phones. The good news for mobile phone suppliers is that this ensures handset replacement is rapid, as research and development evolvesrepparttar 147261 phone into a personal organiser, music player, camera and mobile entertainment centre. We want to enjoy games, video clips and music from our phones andrepparttar 147262 mobile music industry in particular is going from strength to strength. As a result mobile phone giants, such as Sony Ericsson, are exploiting demand withrepparttar 147263 imminent release ofrepparttar 147264 W800i, an advanced competitive and fashion-conscious portable MP3 player market. Although products such as Apple’s iPod have taken off significantly and seem to be in everyone’s pocket, three years sincerepparttar 147266 launch of Apple’s high profile MP3 player, isrepparttar 147267 Californian firm facing competition from an increasing number of industry sectors? Sceptics believerepparttar 147268 latest addition fromrepparttar 147269 Apple team,repparttar 147270 iPod shuffle, is a disappointment, so will consumers look elsewhere for innovation?

Image is a crucial factor that mobile phone providers should take into consideration. Consumers are concerned withrepparttar 147271 way in which a product can reflect their personal identity. Thereforerepparttar 147272 design of a mobile phone is important. Phones that lookrepparttar 147273 part are highly favoured. As a result, mobile phones now come in all shapes, sizes and colours. Some companies, who want to encourage consumer engagement at an early age, have extended their marketing campaigns to include targeting children with brightly coloured mobiles featuring flashing lights

Crankcase Explosion

Written by Thomas Yoon

One ofrepparttar most frightening phenomenon for operators of diesel engines isrepparttar 147255 crankcase explosion. Although many force-lubricated, totally enclosed, reciprocating machines like diesel engines, steam engines, air compressors and many others had been running for many hours without any such problems, still repparttar 147256 problem of crankcase explosion is ever present and we cannot forget about it.

In order to understandrepparttar 147257 phenomenon of crankcase explosion, we have to understandrepparttar 147258 nature of fire, because, after all, an explosion is a very rapid propagation of fire.

A fire will only start whenever three conditions are met: fuel, oxygen, and heat.

A fire can very well start insiderepparttar 147259 crankcase of a diesel engine whenrepparttar 147260 conditions are just right. For allrepparttar 147261 recorded occurrences of crankcase explosions, one factor is common, namely a hot spot. That isrepparttar 147262 heat source.

Now, let us take a look insiderepparttar 147263 crankcase. It housesrepparttar 147264 crankshaft, connecting rod, piston rod, cylinder liner, piston, drive gears or chains andrepparttar 147265 lubrication oil. To prevent lubrication oil loss, protect persons fromrepparttar 147266 moving mechanical parts, prevent contamination ofrepparttar 147267 oil, and many other reasons repparttar 147268 crankcase is totally enclosed and separated fromrepparttar 147269 external environment.

First, let us look atrepparttar 147270 moving parts. There isrepparttar 147271 reciprocating mechanism consisting ofrepparttar 147272 crankshaft, journal bearings, and connecting rod. If it is a crosshead engine,repparttar 147273 crosshead sliding and reciprocating mechanism. Forrepparttar 147274 trunk type engine, there is repparttar 147275 piston andrepparttar 147276 small end bearings.

There are also gears or chains to driverepparttar 147277 camshaft. For reversible engines,repparttar 147278 reversing drive mechanisms. There is also repparttar 147279 thrust bearings atrepparttar 147280 end ofrepparttar 147281 crankshaft to take uprepparttar 147282 driven load. There may also be cooling oil pipes, or cooling water pipes sliding insiderepparttar 147283 crankcase for piston cooling. The piston rod itself may also be sliding through a gland assembly atrepparttar 147284 under piston space.
