he cried and i cried. i told him i needed him, so he had to hang in there. and then i woke up..
If you like his girlfriend don't be mean and try to break them up though. For this step you must be a complete girly girl. Twirl your hair or braid it when your bored in class.
Deposits are formed in ultrabasic rocks, rich in magnesium, by the action of hydrothermal solutions connected with younger granites. In the USSR chrysotile asbestos is mined in the Urals (the Bazhenov and Kiembaev deposits), the western part of Kazakhstan (Dzhetygarina), ....etc

ABSTRACT
Today s technology is in need for speed, but at the same time, we need safety as well. For safety, we need deceleration to the maximum extent. These two things are moreover contradictory factors. For speed, we need engines of maximum efficiency and for keeping this speed in bounds, we need brakes of latest technology. For coping up with today s speed, new materials are introduced in the manufacture of brakes.
In my seminars, I am introducing to you the ceramic disc brakes. Cast iron is extensi ....etc

research paper on ceramic disc brakes

A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a disc in order to create friction that retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulic disc brakes are the most commonly used form of brake for motor vehicles but the principles of a disc brake are applicable to almost any rotating shaft.
Compared to drum brakes, disc ....etc

Until now brake discs have been made up of grey cast iron, but these are heavy which reduces acceleration, uses more fuel and has a high gyroscopic effect.

Ceramic disc brake weigh less than carbon/carbon discs but have the same frictional values with more initial bite and cost a fraction of price. Carbon /carbon discs are used only in Formula 1 racing cars etc, because it is so expensive. More over ceramic brake discs are good even in wet conditions which carbon / carbon disc notoriously fails to do.

But comparing their weight, you will ....etc

Abstract
This paper focuses on the experimental investigation carried out on high strength concrete reinforced with hybrid fibres (combination
of hooked steel and a non-metallic fibre) up to a volume fraction of 0.5%. The mechanical properties, namely, compressive strength, split
tensile strength, flexural strength and flexural toughness were studied for concrete prepared using different hybrid fibre combinations
steel polypropylene, steel polyester and steel glass. The flexural properties were studied using four point bending t ....etc

In this seminars, we examine the feasibility of using thin-film NiTi shape-memory alloys (SMAs) for thermomechanical data storage as an alternative to the polymer thin film used as the data storage medium in the IBM Millipede device.'8' NiTi is a potentially more robust and rapid storage medium than the polymer films currently used for thermomechanical data stor age. For example, the poly(methyl methacrylate) (PMMA) medium ....etc
