What Is The Working Principle of An Electric Motor The working of an electric motor is based on the fact that a current carrying conductor produces a magnetic field around it. To better understand imagine the following situation. Take two bar magnets and keep the poles facing each other with a small space in between.

· Droplet Digital PCR (ddPCR) is a method for performing digital PCR that is based on water-oil emulsion droplet technology. A sample is fractionated into 20 000 droplets and PCR amplification of the template molecules occurs in each individual droplet. ddPCR technology uses reagents and workflows similar to those used for most standard TaqMan probe-based assays.
· Streak Plate Method Principle Procedure Uses. Streak plate technique is used for the isolation into a pure culture of the organisms (mostly bacteria) from a mixed population. The inoculum is streaked over the agar surface in such a way that it "thins out" the bacteria. Some individual bacterial cells are separated and well-spaced from
· Click through the slideshow to see how to make your own ice cream. Prepare your ice cream mix by adding 1 tablespoon of sugar ½ cup of half-and-half (or milk or heavy whipping cream) and ¼ teaspoon of vanilla extract to a small sealable baggie. Add 4 cups of ice cubes or crushed ice to a large gallon-sized baggie.
The first step in making paint involves mixing the pigment with resin solvents and additives to form a paste. If the paint is to be for industrial use it usually is then routed into a sand mill a large cylinder that agitates tiny particles of sand or silica to grind the pigment particles making them smaller and dispersing them throughout the mixture.
· While Mendel s research was with plants the basic underlying principles of heredity that he discovered also apply to people and other animals because the mechanisms of heredity are essentially the same for all complex life forms. Through the selective cross-breeding of common pea plants (Pisum sativum) over many generations Mendel discovered that certain traits show up in offspring without
· thermodynamic cycle where the working fluid is enclosed within the engine. Fluid flow is modulated by changing volumes within the engine. The two pistons of the engine are exposed to a hot source and cold source respectively. The working fluid compresses within the cold space is transferred to the hot space and expands to do work on the piston.
· The order from Scottish Power Renewables is the second commercial order for the second generation P2 Pelamis machine and was installed at EMEC in May 2012. Scottish Power Renewables and E.ON have put in place a unique joint working agreement to learn from operating and maintaining the machines as a wave farm.
Below are few examples of timer circuits used in different applications. 1. Long Duration Timer. This timer circuit is designed to switch on a 12 V load in a solar-powered installation for a preset period at the press of a button. When the period has expired a latching relay disconnects both the load and the controller circuit from the 12 V supply.
Traditional crushing production line is generally composed of vibration feeder jaw crusher third generation sand making machine (fine crusher) sand washing machine
Principle 1 Self-Efficacy. When embarking on a weight-loss journey believing you can reach your goals is actually part of the battle. "Self-efficacy is the confidence or belief we have in our ability to complete a specific task " Grupski says. "We are more likely to take action when

White quartz sand the sand found on sparkling white beaches is attractive but not the best for hourglass-making because it is too angular and does not flow smoothly. Marble dust other rock dust and rock —powder from glass cutting—and round sand grains like those of river sand are best for sand
· Third generation sequencing can sequence a human genome requiring little to no effort within a matter of hours and is under development currently. It sequences genes at the molecular level i.e. instead of performing DNA fragmentation and sequencing by amplification and synthesis used by second generation sequencing methods it can sequence a
· construction and testing of a multipurpose machine that produces high quality blocks/bricks for low cost housing. That is for low income communities/earners. The constructed motorized compressive earth (CEB)/ machine can produce on average a total of 2 215 bricks per day and 950 blocks per day.
· Autoclave Definition. An autoclave is a machine that provides a physical method of sterilization by killing bacteria viruses and even spores present in the material put inside of the vessel using steam under pressure.. Autoclave sterilizes the materials by heating them up to a particular temperature for a specific period of time.
· Work is performed by applying a force over a distance. These six simple machines create a greater output force than the input force the ratio of these forces is the mechanical advantage of the machine. All six of the simple machines listed here have been used for thousands of years and the physics behind several of them were quantified by the Greek philosopher Archimedes (ca. 287–212

· The six basic steps in making sand castings are (i) Pattern making (ii) Core making (iii) Moulding (iv) Melting and pouring (v) Cleaning Pattern makingPattern Replica of the part to be cast and is used to prepare the mould cavity. It is the physical model of the casting used to make the mould. Made of either wood or metal.
· Darwin and Natural Selection. Most educated people in Europe and the Americas during the 19th century had their first full exposure to the concept of evolution through the writings of Charles Darwin.Clearly he did not invent the idea. That happened long before he was born. However he carried out the necessary research to conclusively document that evolution has occurred and then made the
· The third stage of the design process involves analyzing your solu-tion. This can be accomplished by creating a detailed design of the solution. One suggested analysis method includes creating a 3-D solid model of the solution which can have kinetics applied to its parts moving them through their range of motion to look for prob-lems.

· Natural selection is the mechanism that causes evolutionary change helping organisms adapt to their environment. Charles Darwin and Alfred Wallace published simultaneous papers in the subject in 1858 and Darwin subsequently published many additional works on evolution and natural selection.
Sand casting the most widely used casting process utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part called the casting sand casting typically has a low production rate. The sand casting process involves the use of a furnace
· An electrical motor is an electromechanical device that converts electrical energy into mechanical energy. In the case of three-phase AC (Alternating Current) operation the most widely used motor is a 3 phase induction motor as this type of motor does not require an additional starting device.These types of motors are known as self-starting induction motors.

· Principle of Gene Cloning A fragment of DNA containing the gene to be cloned is inserted into a suitable vector to produce a recombinant DNA molecule. The vector acts as a vehicle that transports the gene into a host cell usually a bacterium although other types of living cell can be used.
