The most common laboratory apparatus and their uses are listed below: Beaker = A container used for measuring the liquid. Barrette = Used for measuring the volume of the solution. Wire gauze = used for spreading the heat of a burner(flame). Test tube brush = It is used to clean the test tube. Droper = It is used for adding the solution drop by drop. Magnifying glass = It is used for viewing the minute objects. Filter paper = It is used for separating the liquid and the precipitate. Stirring rod

A diode is a two-terminal device‚ having two active electrodes‚ between which it allows the transfer of current in one direction only. Diodes are known for their unidirectional current property‚ wherein‚ the electric current is allowed to flow in one direction. Basically‚ diodes are used for the purpose of rectifying waveforms‚ and can be used within power supplies or within radio detectors. They can also be used in circuits where ’one way’ effect of diode is required. Most diodes are made from semiconductors

Today‚ I’m going to explain how aerogel (otherwise known as frozen smoke) is so unique to any other known materials in the world. An aerogel is a synthetic porous ultra-light material derived from a gel‚ in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and thermal conductivity. Nicknames include "frozen smoke"‚ "solid smoke"‚ "solid air" or "blue smoke" owing to its translucent nature and the way light scatters in the material;

CHAPTER ONE 1.1 BACKGROUND TO THE STUDY Electronics has so much improved to the extent of applying its use to the health sector. In Africa there has been a very high infection rate of the malaria parasite due to the breeding environment conducive for its reproduction available in almost in all regions.About 3.3 billion people half of the world ’s population are at risk of malaria. In 2010‚ there were about 219 million malaria cases (with an uncertainty range of 154 million to 289 million)

In this assignment‚ we are assign to construct a 2 button type Ac motor control system. The 2 type button means that there are only 2 buttons which is the stop button and the forward button. The successful build the whole system‚ a few component are very critical in this system. Circuit breaker First is the circuit breaker. Circuit breaker is a switch which is designed to prevent damaging the circuit when there is over load or short circuit. But the circuit breaker works differently compare

Previously existing micro electromechanical systems (MEMS)-based IOP sensors based on capacitance meas-urement are opaque and rigid. Chen et al.

and non-inverted logic using pseudo NMOS implementation. In any transition either the pull up or pull down network is activated meaning the input capacitance of the inactive network loads the input. Moreover pmos transistors have poor mobility and must be sized larger to achieve comparable rising and falling delays further increasing input capacitance. In this paper‚ this problem is addressed with the realization of the circuit which requires the implementation of inverted logic using pseudo nmos
