a vessel and heated initially to poln temp. by a hot jacket to initiate the reaction. Monomer is added with constant agitation/ stirring for effective heat and mass transfer. Polymerisation reaction involves extensive bond formation in homogenous system and is exothermic. (25 – 30% poln) Post poln stage :- As the reaction proceeds‚ the reaction mixture becomes viscous and is then transferred to the main reactor and is placed in a thermostat maintained at a higher temperature. After a known period

researched four types of organizational culture‚ which may be accepted by companies. The first type is “the power culture”‚ which means that the power is concentrated in one person and dominated by one person in the company (Greener‚ 2010). One person influences all decision-making. A type of organization with this cultural type is able to solve problems and provide solutions easily‚ however solutions depend on the central person for their success. The fact is that with this cultural type it is difficult

WHAT IS A SOFTWARE A set of instructions that cause a computer to perform one or more tasks. The set of instructions is often called a program or‚ if the set is particularly large and complex‚ a system. Computers cannot do any useful work without instructions from software; thus a combination of software and hardware (the computer) is necessary to do any computerized work. A program must tell the computer each of a set of minuscule tasks to perform‚ in a framework of logic‚ such that the computer

electric power system‚ a fault is any abnormal electric current. For example‚ a short circuit is a fault in which current bypasses the normal load. An open-circuit fault occurs if a circuit is interrupted by some failure. In three-phase systems‚ a fault may involve one or more phases and ground‚ or may occur only between phases. In a "ground fault" or "earth fault"‚ charge flows into the earth. The prospective short circuit current of a fault can be calculated for power systems. In power systems‚ protective

Types of computers Firstly‚ what is a computer? Well‚ a modern computer is typically an electronic or digital device that manipulates data. Computers can execute a pre-recorded list of instructions know as a “programme”. Large amounts of data can be stored on computers and be quickly accessed‚ edited and stored. When it comes to computers there are several different types: * High Performance System (HPS) * Workstations * Personal Computer * Laptop / Notebook * Palmtop These

Types of Infrastructure Infrastructure is divided into two major classifications‚ "hard" and "soft". "Hard" is obviously the roads‚ bridges‚ etc. It also relates to the big physical networks essential for the functioning of a modern industrial nation Hard infrastructures refers to physical facilities or installations needed to operate‚ manage and monitor a system with the intention that the structures to be permanent whereas "soft" infrastructure is human capital and institutions that develop it

| Types Of Gears | Gear Type | Description | Photo | Spur Gears | Spur gears are by far the most common type of gear and with the exceptions of the "cog" the type of gear that has been around the longest. Spur gears have teeth that run perpendicular to the face of the gear. | | Helical Gears | Helical gears are very similar to spur gears except the teeth are not perpendicular to the face. The teeth are at an angle to the face giving helical gears more tooth contact in the same area. Helical

Types of Learning 1. Non-associative learning - refers to "a relatively permanent change in the strength of response to a single stimulus due to repeated exposure to that stimulus. Changes due to such factors as sensory adaptation‚ fatigue‚ or injury do not qualify as non-associative learning." Non-associative learning can be divided into habituation and sensitization. ++ Habituation ++ -is a decrease in behavioral responsiveness that occurs when a stimulus is repeated frequently

Types of Buckling Engineering is one discipline that is based on several different phenomenon and concepts. Each concept in engineering is as important as other and they all work together to give rise to some new techniques. One phenomenon that is extremely beneficial and widely used in engineering and science is buckling. Buckling is nothing but a phenomenon of mathematical instability‚ which leads to a special failure mode. When a system in equilibrium is subjected to additional load‚ it buckles
