BlackBerry maker RIM Co-CEO Jim Balsillie in the company after the release of the third quarter took a JPMorgan analyst Hall Rod interview. He said in an interview, RIM in some areas far ahead in Apple, especially upcoming entry next tablet.

Hall interview questions are basically revolves around how RIM compete with Apple and Google. Leslie Barr said: Entries are latecomers, Apple and Google coach purses will (tied house) in the digital home integration direction.

He noted that introduction has been identified in the Tablet PC. The pro ....etc

Nowadays maintenance-free lead-acidbatteries are common in vehicles,inverters, and UPS systems. If thebattery is left in a poor state of charge, itsuseful life is shortened. It also reduces thecapacity and rechargeability of the battery.For older types of batteries, a hygrometercan be used to check the specific gravityof the acid, which, in turn, indicates thecharge condition of the battery. However,you cannot use a hygrometer for sealedtypemaintenance-free batteries. The onlyway to know their charge level is by checkingt ....etc

ABSTRACT
This project has been a great learning experience for me; at the same time it gave me enough scope to implement my analytical ability. This project as a whole can be divided into two parts:
The first part gives an insight about the footwear and its various aspects. It is purely based on whatever I learned at Sarup Tanneries. One can have a brief knowledge about footwear and all its basics through the project. Other than t ....etc

The Lead Acid Battery
Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by automobile starter motors.

Lead and chromium as limiting factors in recycling textile industrial sludge as an amendment in crop production
Abstract
Textile and dyeing industry is one of the leading industries in Tamilnadu state of India. The coagulant process followed for treating the wastewater generated from this industry leads to sludge accumulation with a production of daily average of 10 tonnes in each Common Effluent Treatment Plant (CETP). As the sludge contained 17.2 per cent of Ca, its ameliorative potential as an amendment al ....etc

There are 3 leads in a transistor viz. collector,emitter and base. When a transistor is to be connected in a circuit,it is necessary to know which terminal is which.
There are three systems in general from which we can determine which terminal is which,they are as follows

1. When the leads of the transistor are in same plane and unevenly spaced then they are identified by the position and spacing of leads. The central lead is the base lead.the collector lead is identified b ....etc
