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 a

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.

The Great Wall of China is a series of stone and earthen fortifications in China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire from Xiongnu attacks during the rule of successive dynasties. Several walls, referred to as the Great Wall of China, were built since the 5th century BC. One of  the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang; little of it remains; it was much farther north than the current wall, which was built during the Ming Dynasty. The Great Wall stretches over approximately 6,400 km (4,000 miles) from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia, but stretches to over 6,700 km (4,160 miles) in total.At its peak, the Ming Wall was guarded by more than one million men. It has been estimated that somewhere in the range of 2 to 3 million Chinese died as

Chesapeake Bay Bridge-Tunnel The  Chesapeake Bay Bridge-Tunnel ( CBBT )  is a 23 mile long bridge and tunnel system that connects southeastern Virginia with Delmarva Peninsula in the United States. The bridge connects the following independent cities Virginia Beach, and Norfolk, Virginia to Cape Charles in Northampton County along the eastern shore of Virginia. The Chesapeake Bay Bridge-Tunnel uses a combo of tunnels and bridges over two separated shipping channels using four artificial islands built in the bay as portals. The bridge-tunnel was opened on April 15th, 1964, in August 1987 it was officially named the Lucius J. Kellam Jr. Bridge-Tunnel after one of the civic leaders who worked for its development. However, it still is best known as Chesapeake Bay Bridge-Tunnel. The bridge part of the Chesapeake Bay Bridge-Tunnel as far as I can know is 15.6 Miles long which is why this bridge is placed at number at the worlds 9th longest bridge and 7th longest over water and 4th

The Earthscraper, designed by  BNKR Arquitectura , is the Skyscraper’s antagonist in the historic urban landscape of Mexico City where the latter is condemned and the preservation of the built environment is the paramount ambition. It preserves the iconic presence of the city square and the existing hierarchy of the buildings that surround it. More images and architects’ description after the break. The Historic Center of Mexico City is composed of different layers of cities superimposed on top of each other. When the Aztecs first came into the Valley of Mexico they built their pyramids on the lake they found there. When a new and bigger pyramid was conceived and the Aztec Empire grew in size and power, they did not search for a new site, they just built on it and around the existing one. In this manner, the pyramids are composed of different layers of historical periods. When the Spanish arrived in America and ultimately conquered the Aztecs, they erected their Christian temple

The Magdeburg Water Bridge  (German: Wasserstraßenkreuz) is a navigable aqueduct in Germany, opened in October 2003 . It connects the Elbe-Havel Canal to the Mittellandkanal, crossing over the Elbe River. It is notable for being the longest navigable aqueduct in the world, with a total length of  918 metres (3,012 ft). The Elbe–Havel Canal and Mittelland Canal canals had previously met near Magdeburg but on opposite sides of the Elbe, which was at a significantly lower elevation than the two canals. Ships moving between the two had to make a 12-kilometre (7.5 mi) detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before ascending up to the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. History Canal engineers had first conceived of joining the two waterways as far back as 1

Crown Wheel Preload To achieve the low noise level, housing rigidity and accurate gear alignment are essential with a hypoid gear. This necessitates elimination of slackness in the crown wheel bearings by preloading. Out of the various methods used to measure the preload, the most common one is to measure the spread (outward deflection) of the bearing caps when the adjusters are screwed together. As an example, a preload cap-spread of 0.1 mm indicates that after preloading the side bearings, the distance between the bearing caps has increased by 0.1 mm.                                                                   Fig. 26.42. Final drive adjustment When shims are employed to control the backlash, the preload is obtained by increasing the shim thickness on each side of the crown wheel and the shims are added after the backlash has been set. Axles with this construction need a special tool to 'spread the caps' before the crown wheel assembly is removed or refitted. Figure 26.

Crown Wheel Adjustment After setting the pinion, the crown wheel is installed in the assembly. The correct bearing cap must be used during this operation, as these are not interchangeable. Backlash is adjusted at this stage by moving the crown wheel towards or away from the pinion. Prior to the final measurement of backlash with a clock gauge, it is necessary to ensure that the crown wheel run-out is within the recommended limits. Meshing of the gear is checked by applying a smear of marking compound to the driving side of a few crown wheel teeth and then turning the pinion in the direction of rotation while applying a resistance to the crown wheel. The marking thus obtained indicates the mesh of the gears with respect to pinion position and backlash. Figure 26.41 illustrates the change, in relation to the correct marking, when the pinion position is changed.  A 'correct' marking indicates only a limited contact between the teeth under light-load test conditions. But if full lo

Pinion Adjustment The pinion bearing preload adjustment depends on the type of spacer used to hold the bearings apart. Two main arrangements using a rigid spacer and a collapsible spacer are illustrated in Fig. 26.40. A bearing arrangement with a rigid spacer has a series of shims to control the static load on the bearings (Fig. 26.40A). On this arrangement the pinion nut is fully tightened before the preload is measured and shims are either added or removed if found incorrect. With this typeof spacer, the renewing of the pinion oil seal is simplified, because the seal replacement does not alter bearing preload provided the pinion nut is fully tightened Fig. 26.40. Pinion bearing adjustment The use of a collapsible spacer (Fig. 26.40B) saves time on the preload operation. While holding the bearings in alignment, this ductile steel spacer collapses under-pressure from the pinion nut so that the preload can be set in one operation. With the pinion, bearings and seal in position, the nut

Preloading of Bearing To support both the crown wheel and pinion, adjustable taper roller bearings are normally used in a final drive assembly. If each bearing is adjusted for a small clearance between the rollers and tracks, end-float and misalignment of the gear result. This causes gear noise and premature bearing failure, because of incorrect meshing and uneven loading respectively. Even if the clearance is removed, similar effects are produced due to the elasticity of the bearing material unless this is also taken into account. To overcome these problems, all adjustable bearings employed for final drives are preloaded by forcing them together to the position they occupy when the unit is under full load. Preloading is carried out through the means provided for the adjustment. In the case of pinion bearings the extent of this pre-compression is indicated by the torque required to rotate the pinion in its housing. The recommended preload normally states the conditions under which it i

Bevel-drive Adjustment Currently used bevel drive operates under severe conditions, but extends satisfactory service provided correct adjustment of the gear is made. Every manufacturer provides detailed specifications of special tools to be used, clearances to be maintained, etc. It is necessary to strictly follow this information before attempting such an overhaul. The final drive produces noise due to the bearing defects or incorrect meshing, which may be caused by bearing wear. Usually noise or 'whine' on the drive is produced due to the gear with too deep in mesh, and noise on the over-run is caused by insufficient depth of mesh. The cause for a final-drive noise should be determined soon whenever it develops. Misaligned gears 'mate' to the new position, so it becomes impossible to obtain a quiet operation even when the adjustment is corrected. A delay in repair may require the installation of a new crown wheel and pinion as well as bearing.

Worm and Wheel Drive Since this drive is expensive, it is rarely used nowadays as a final drive on light vehicles, but is still used on heavy vehicles. However, this type of gear has a number of other applications on motor vehicles. Various arrangements, illustrated in Fig. 26.38, can be employed to provide a very quiet and long-lasting gear, but efficiency is less than the bevel (94 percent against 98 percent). This type of gear provides a large reduction in a small space. The worm may be mounted below (under-slung) or above (overhead) the wheel. An hour-glass or Hindley worm embraces more teeth than the straight worm but adjustment becomes more critical. Fig. 26.38. Worm drives. The sliding action of the worm causes friction, which is reduced by using a worm wheel of phosphor-bronze and a worm of case-hardened steel, but still the unit becomes hot. A large, well-cooled sump is incorporated to reduce oxidation of the oil at high temperature, which otherwise causes the oil to thicken.

Work Safe with Computer Are you spending a lot of time sitting at the computer, doing school work or playing games? Working with a computer for long hours can affect different parts of the body, like our hands, wrists, back, and eyes. If you want to keep these parts as healthy as possible then you have to take some precautions. Sitting Square in Your Chair: One of the most important things you should do at the computer is sitting in your chair. This means keeping your body straight when you’re sitting with your behind in the center of the seat. Your legs should come out straight with your knees and your feet don’t reach the floor, use a footrest. Your back should be touching the seat back the keyboard while you type. And if you can use a seat that has a support for your lower back, that’s even better. Typing time: And speaking of typing: you don’t need to hit those keys very hard to type. A light touch will do the job. While you’re typing, make sure your fingers don’t have to

Wheel Alignment Checking and Adjustment The alignment for suspension and steering linkage is usually checked and adjusted if, GO abnormal tyre were exists, (ii) the automobile handling is felt improper, (Hi) the suspension has been repaired, or (iv) a normal preventive maintenance check becomes necessary. In the past the wheel alignment was measured using a trammel gauge, but nowadays either an optical or an electronic gauge is used. Before tracking the wheels, the following preliminaries should be undertaken. (a) The tyre pressures are checked. (b) The correct load on the vehicle is ensured. (c) The wheels are positioned in the straight ahead position. (d) The vehicle is moved forward to settle the steering. (e) The run-out (buckle) of the wheel in checked and the maximum run-out is positioned so that it does not affect the alignment measurement. Prior to aligning the front suspension and steering systems, the factors to be ascertained that the suspension pivots and ball joints are i

Project Icarus is an ambitious five-year study into launching an unmanned spacecraft to an interstellar destination. Headed by the Tau Zero Foundation, a non-profit group of scientists dedicated to interstellar spaceflight, Icarus is working to develop a spacecraft that can travel to a nearby star. Dr. Robert Adams, study lead in the Advanced Concepts Office at the NASA Marshall Space Flight Center and Lead Designer for the Mission Analysis and Performance Module for Project Icarus, explains the realities behind getting an interstellar spacecraft to its destination. WIDE ANGLE: Project Icarus : Reaching for Interstellar Space One critical feature of any interstellar voyage is the "mission analysis," which organizes science objectives, plots movement through space and determines abort and correction scenarios. Some refer to this effort as "trajectory analysis" or "astrodynamics" but it encompasses more than simply plotting a path through the heavens. Com
