1. INTRODUCTION Nano materials have inmost a huge concentration in the last two decades because of their unique properties that find potential applications in many fields of science and technology. It has grown explosively in the last decade, because of the increasing availability of methods, synthesis of nanomaterials as well as tools of characterization and manipulation. Nanotechnology makes us to believe that we would have the ability to create anything that we could precisely define. Synthesis

CASTROL INTRODUCTION Castrol is now developed and known to be an excellent international brand in the automobiles and industrial lubricants sector and its known for presenting an extensive assortment of greases, oils and related products for mainly those applications that require lubrication. Charles Wakefield in the year 1899 had established The Wakefield Oil Company. "Castrol" as a brand name was resultant of the addition of castor oil by the researchers in the new lubricant formulations they were

LITERATURE REVIEW 1. Etsion and Burstein[12] developed a mathematical model to allow performance prediction of all non-contacting mechanical seals having a regular micro-surface structure in the form of hemispherical pores. Seal performance such as equilibrium face separation, friction torque and leakage across the seal are calculated for a range of seal pressures, pore sizes and pore ratio of the ring surface area. An optimum pore size was found that depends on other variables and corresponds to

CERAMIC FEMORAL HEAD AND CUP ANATOMY OF THE HUMAN HIP The human hip is a ball and socket joint, which allows for movement in all directions. The femur is the long bone of the upper leg which contains two distinct morphological types of bone; the cortical (compact) bone and the cancellous (spongy) bone. At the top of the femur is a mass of bone known as the femoral head, which fits into the acetabulum; a cavity in the pelvis. The synovial fluid moves throughout the pores of the cartilage to

In the poem “Barbie Doll,” the evident theme is don’t conform to society's standards of women. When the girl in the poem is growing up, she was like all the other girls her age: “presented dolls that did pee-pee / and miniature GE stoves and irons / and wee lipsticks the color of cherry candy.” (2-4). In the quote, the author uses symbols to show that girls are supposed to act a certain way, primarily as housewives or stay at home moms. They are given dolls that act like children which are symbolic

The UA developed Ni doped DLC solves the problem of compatibility of DLC coatings with lubricant additives for many applications including gears. The coating makes gears much more durable and long lasting in addition to improving efficiency by reducing friction losses. Now compatible with fully formulated lubricants, given the properties of DLC (please refer to technology description) our coating outperforms other coating technologies such as nitride based coatings. The coating can be produced with

When working in a dental laboratory there are many safe operating procedures that should take place.Dental pumice is used as an abrasive for finished and polishing of dental appliances. Pumice contains crystalline silica , its very harmful substance when breathed and can cause severe breathing problems such as silicosis and a group of lung diseases. When working with pumice we must ensure to always wear gloves as it can be drying on the skin , always wear some type of face mask and this must be insured

Changing the oil on a vehicle is not really that difficult. Replacing the oil in a vehicle helps it run more efficient, and makes it last longer. Things that are required to change the oil in your vehicle is the new oil, new oil filter, an oil bucket, and a lift so it can be picked off the ground. Changing the oil in your vehicle at the right time will make your vehicle perform better, not wear out the motor as much, and will help you out with other problems it might also have. First, you will
