Why to Study Mechanical Engineering???

Image
Sluggish economy and slow pacing market hardly hits the job industry.  The number of jobs opportunities growing is getting scarce, in such a crunch the decision of which career to choose and which course to enroll in becomes really important questions to ponder over. In stronger market scenarios, the jobs pertaining to each discipline as in mass communication, arts and other subjects get generated in ample. Professionals taking up studies in these disciplines easily find relevant jobs matching their areas of skills and expertise but the fall in the job market graph affects severely. Many professionals pursue jobs which are in no way related to their profiles. Few works in call centers and few keep on exploring job sites to get their career started. In recent survey it has been revealed that around 20% of UK students will be leaving their Universities with no immediate future job prospects. The question of basic economics is th

LATEST MECHANICAL ENGINEERING INNOVATION People have been looking for ways to extend the life of a battery, be it a AAA, AA or even the D-size. What we have here is the ONE=TWO Spring Battery. The design is quite self explanatory.The spring basically extracts every little bit of juice form the battery!

LAW OF THE WILD SAYS KILL ONLY WHEN YOU ARE HUNGRY

Image
Photographer Michel Denis captured these amazing pictures on safari in Kenya. He was astounded by what he saw: "These brothers have been living together since they left their mother at about 18 months old, On the morning he saw them, they seemed not to be hungry, walking quickly but stopping sometimes to play together. 'At one point, they met a group of impala who ran away.. But one youngster was not quick enough and the brothers caught it easily'." Then extraordinary scenes followed; they just walked away without hurting him. Life is short... forgive quickly, love truly, laugh uncontrollably...and never regret anything that made you smile.

Dangerous creatures have Co-existence and mutual assistance !!!!

Image
The incident occurred in the Indian state of Punjab. Two puppies fell into a well. Their mother ran near the well and started barking, and attracted the attention of the owner, who looked inside and to his surprise there was a king cobra at the bottom, which didn't pose any threat to the puppies. Moreover, the reptile, looked after the puppies, by not allowing them to cross to the other side, wher e they could possibly drown, when the well is filled with water. In general, they spent around 48 hours together at the bottom and in these 48 hours the cobra sat quietly next to them. When help finally arrived from the forest department, the cobra slithered to the other end of the well. The puppies were not injured at all and the reptile was immediately taken into the woods and was released into the wild. Even the most deadly and dangerous creatures on earth know what Co-existence and mutual assistance is. The human race is in this respect far behind, and this is our biggest drawback.

Dolphins Help Save Dog from Drowning!

Image
On Marco Island, Florida a group of dolphins came to the aid of a lost Dog that had fallen into a canal and couldn't get out. The dolphins made so much noise, it attracted the attention of people living nearby, who then rescued the dog. The Dog was believed to have spent 15 hours in the canal water before he was pulled out by fire personnel and reunited with  his owner. One of the people whose attention was captured by the noisy, demonstrative dolphins said, "They were really putting up a ruckus, almost beaching themselves on the sandbar over there. If it wasn't for the dolphin, I would have never seen the dog.” (Source: ABC7news) He said also if the dolphins hadn't persisted enough to get their attention, they dog would have died in the canal. The dog had fallen over the edge of a concrete wall down into the water far enough that it had no chance of getting back up by itself. The dog was exhausted from being in the cold water for hours, and most likely suffering fr

Horrible Fact about KFC

Image
KFC has been a part of American traditions  for many years. Many people, day in and  day out, eat at KFC religiously. Do they  really know what they are eating? During a re cent study of KFC done at the University of New Hampshire, they found some very upsetting facts. First of all, has anybody noticed that just recently, the company has changed their name? Kentucky Fried Chicken has become KFC. Does anybody know why? We thought the real reason was because of the "FRIED" food issue. IT'S NOT!! The reason why they call it KFC is because they can not use the word chicken anymore. Why? KFC does not use real chickens. They actually use genetically manipulated organisms. These so called "chickens" are kept alive by tubes inserted into their bodies to pump blood and nutrients throughout their structure. They have no beaks, no feathers, and no feet. Their bone structure is dramatically shrunk to get more meat out of them. This is great for KFC. Because they do no

What mystery is going on with the FETUS ? ? ?

Image
Recently, one human rights advocate recorded allegation of doctors eating dead fetus after performing abortions at Shenzhen hospitals. To confirm the allegation, an undercover reporter from Eastern Express visited a state owned health center for women and children and asked a female doctor for a fetus. The doctor said that the hospital was out of stock but reminded the reporter to come back. When  the reporter went back to the hospital, the doctor offered ten fetuses for free. In another state-run hospital in Shenzhen, a nurse said that fetuses were in short supply and the price could go up from $10 to $20. In another clinic, one doctor offered the reporter a full-term fetus and recommended that it had the best healing ingredients. The disturbing human rights abuse comes from a distorted view of unborn children in Chinese culture. Traditionally, ancient Chinese considered ingestion of firstborns, aborted fetuses and placentas as part of a mother’s flesh. An unborn child has no perso

Who Invented Thermodynamics?

Image
Biography of Sadi Carno t: (An inspiration for every mechanical engineering student) The applications of the laws of thermodynamics has led to the discovery of important machines like automobile, ships, airplanes , refrigerator, air-conditioner, etc. A young man, Nicholas Leonard Sadi Carnot of 36 years of age is considered to be the father of thermodynamics. It is emotional for many of us to know that inventor of an important field of thermodynamics was a boyish scientist who died at the young age of a mere 36 years. Sadi Carnot is a shining example for the young generation for it was his hard work and inventions which has lead to the design, developments and manufacture of present day automobiles. Personally, when I remember the contributions of this boy, I get goosebumps. Had he lived little longer, I’m sure he would have been involved in many greater inventions. Though lots of research has been carried out in the field of thermodynamics, the works of Sadi Carnot are considered

CLEAN YOUR KIDNEYS WITH LESS PRICE

Image
Years pass by and our kidneys are filtering the blood by removing salt, poison and any unwanted entering our body. With time, the salt accumulates and this needs to undergo cleaning treatments and how are we going to overcome this? It is very easy, first take a bunch of parsley or Cilantro ( Coriander Leaves ) and wash it clean Then cut it in small pieces and put it in a pot and pour clean water and boil it for ten minutes and let it cool down and then filter it and pour in a clean bottle and keep it inside refrigerator to cool. Drink one glass daily and you will notice all salt and other accumulated poison coming out of your kidney by urination also you will be able to notice the difference which you never felt before. Parsley (Cilantro) is known as best cleaning treatment for kidneys and it is natural!

WHY WE SHOULD VISIT TEMPLES?

Image
There are thousands of temples all over India in different size, shape and locations but not all of them are considered to be built the Vedic way. Generally, a temple should be located at a place where earth's magnetic wave path passes through densely. It can be in the outskirts of a town/village or city, or in middle of the dwelling place, or on a hilltop. The essence of visiting a temple is discussed here. Now, these temples are located strategically at a place where the positive energy is abundantly available from the magnetic and electric wave distributions of north/south pole thrust. The main idol is placed in the core center of the temple, known as "*Garbhagriha*" or *Moolasthanam*. In fact, the temple structure is built after the idol has been placed. This *Moolasthanam* is where earth’s magnetic waves are found to be maximum. We know that there are some copper plates, inscribed with Vedic scripts, buried beneath the Main Idol. What are they really? No, they ar

Relationship between "Q" and "U"

Image
        In English we are having 26 different types of alphabets which make different types of word formation. and our daily communication goes with these letters only. with a keen observation we all can identify that the what is the relationship between the letter "Q" and "U" in the English alphabetical system. you may think this is some what funny and by observing that you understand that the there is no word that starts with the letter "Q" and commonly the second letter is "U". at the same time you have to find the division of the these two words and find the word that FIRST LETTER "Q" and SECOND LETTER "U" should not be there. is there any kind of explanation with all people ??? I HOPE YOU FIND A BETTER ANSWER

Soft corner of wild animals towards small. . .

Image
The extraordinary scene was captured  by photography student Casey  Gutteridge at the Santago Rare  Leopard Project in Hertfordshire.  Casey was astounded by the mouse's  behavior. He said: "I have no idea where the mouse came from - he just appeared in the enclosure after the keeper had dropped in the meat for the leopard." "He didn't take any notice of the leopard, just went straight over to the meat and started feeding. But the leopard was pretty surprised, she bent down and sniffed the mouse and flinched a bit like she was scared. In the meantime the mouse just carried on eating like nothing had happened." She gave him a shove with her nose, but even a gentle shove does not deter the little creature from getting his fill.

COAL TO ELECTRICITY

Image
Since the turn of the 20th Century, the use of electricity has been a fundamental part of the various aspects that make up our daily lives. Without electricity, the Industrial Revolution would not have been possible, and the world we know today would be a much darker place. Almost all the energy we use comes from various fossil fuels, in particular, coal.  Coal power is one key electricity source that is responsible for generating vast quantities of reliable, inexpensive power to nations around the world. In recent years, coal has become increasingly important, especially as the supplies of natural gas and oil continue to diminish. In addition, the world's coal reserves are expected to last centuries. Due to these factors, coal-based power is used heavily around the world. Resource http://coalpower.wikispaces.com/

The Pont du Gard (Gard Bridge)

Image
"The Pont du Gard (Gard Bridge)"   is an ancient Roman aqueduct  bridge that crosses the Gardon  River in Vers-Pont-du- Gard near Remoulins, in the Gard  département of southern France .  It is part of the Nîmes aqueduct, a  50 km-long (31 mi) structure built  by the Romans to carry water  from a spring at Uzès to the  Roman colony of Nemausus  (Nîmes). Because the terrain  between the two points is hilly, the  aqueduct – built mostly  underground – took a long, winding  route that crossed the gorge of the  Gardon, requiring the construction  of an aqueduct bridge. Built in the  1st century AD, the Pont du Gard  is the highest of all Roman  aqueduct bridges and is the best preserved with the Aqueduct of Segovia . It was added to UNESCO's list of World Heritage Sites in 1985 because of its historical importance.

World's first car drivable inside water!!!

Image
The sQuba, developed by Swiss company Rinspeed , is the world's first car that can be driven both on land and under water.The original idea by Rinspeed founder and CEO Frank M. Rinderknecht was inspired by the 1977 James Bond film The Spy Who Loved Me .The chassis from the Lotus Elise is used as the base for this vehicle.  The sQuba is a zero-emission, all  electric vehicle which uses three electric motors, one for land travel, two for water. It drives on land powered by its electric rear-wheel drive powertrain, utilizing rechargeable lithium-ion batteries. Upon entering water, it floats on the surface until the operator floods the interior to submerge it. It can be submerged to a depth of 10 metres (33 ft), powered by twin electric-powered propellers supplemented by two Seabob water jets. It "flies" when underwater, like a submarine, as it is not designed to drive along the surface at the bottom of the water. The car's top land speed is 120 km/h (75 mph) . On

How Fuel Ionizers Work?

Fuel ionizer is one of the simple magnet ionizer gadgets which was newly introduced into the market after a big scientific research on the improvement of the fuel efficiency and increase the efficiency of the engine with a simple installation process. Fuel ionizers are the energy tubes which are made of aluminium and steel case. Scientifically we can say that the fuel consumption in the internal consumption which is based on the concept that converts the 30-35% of the neutral ions within the petroleum fuel. Ionizers make the ions recharge the neutral molecules produces the charged ion pairs and make them as a useful energy and these become the stable energy source. This type of ionization process can be implemented in some of the unstable energy source which are being used are all types of gasoline products, diesel, LPG [Liquid Petroleum Gas] and some of the oil which are used in the furnaces. Fuel ionizers basically work on the internal combustion engines which help in po

WEAVING

Image
Weaving is one of the processes that required in textile in terms of producing a fabric. From the fiber then become a yarn through some other process, weaving is a process of interlacing two types of yarn known as warp or ends (run parallel to the weaving machine known as loom) and weft or filling yarn (run perpendicular to the loom) to produce a rigid fabric. In order to interlace the  warp and weft yarn, there are three operations which often called primary motions are necessary: Shedding- The process of separating the warp yarn into two layers by raising the harness to form an open area between two sets of warps and known as shed. Picking- The process of inserting the filling yarn through the shed by the means of the shuttleless while the shed is opening. Beating- The process of pushing the filling yarn into the already woven fabric at a point known as the fell and done by the reed.

AVAILABILITY BASED TARRIF (ABT)

Availability Based Tariff   (ABT) is a frequency based pricing mechanism for electric power. The ABT falls under   electricity market   mechanisms to charge and regulate power to achieve short term and long term network stability as well as incentives and dis-incentives to market participants against deviations in committed supplies as the case may be. ABT Mechanism ( Energy policy of India ) is adopted in India (ABT Order dated January 2000 of CERC) and in a few other countries for pricing bulk power across various stakeholders. ABT concerns itself with the tariff structure for bulk power and is aimed at bringing about more responsibility and accountability in power generation and consumption through a scheme of incentives and disincentives. As per the notification, ABT was initially made applicable to only central generating stations having more than one SEB/State/Union Territory as its beneficiary.  Through this scheme, the Central Electricity Regulatory Commission   (CERC)
