Donald Trump blames India again for taking US jobs...Is this right?

Donald Trump, the controversial Republic an presidential frontrunner, today again blamed India for taking away jobs from Americans, pledging to bring them back if elected as a president even as the Trump Mania appeared to have picked up in the US ahead of "Super Tuesday" showdown.The 69 year old state tycoon who became a politician only last summer has been drawing thousand of crowd across the country, hoped to "seal the deal", coming Tuesday by winning Republican primary in all 11 states.Is Donald Trump is afraid of Indians or Indian society or the Americans are not well qualified for the jobs in USA since they are hiring Indian? I can't think or ought to think about that but Donald really this is the one step you are going to take to give jobs the American and really American want this?

Addressing a crowd of roughly 5000 people a big US primary election standard-- inside the hanger of a local airport here, Trump sold the dream of "making america great" by promising to bring back the jobs from countries like India,China,Japan and Mexico.

Is this the reality or really he will bring it back?

Electrical Heating is best method of heating...

Electrical heating is one of the best method of heating elements that are hard to be heated or melted. Followings are the advantages of electrical heating technique over other techniques:-

a) Economical- Electrical heating is economical as electric furnaces are cheaper in initial cost as well as maintenance cost. It does not require any attention during operation so labour cost reduces.

b) Cleanliness- Since dust and ash are completely eliminated in electric heating system, so it is clean system, so leaning cost reduces.

c) Absence of flue gases- Since no flue gases has been produced in this system,so there is no risk to atmosphere therefore non polluting process.

d) Ease of control- Simple, accurate and reliable can be controlled by hand or by fully automatic using PLC.
e) High efficiency of Ultilization- The overall efficiency of electric heating is comparatively higher since in this system the source i bought near to the point where heat is produced.
f) Better working condition- In electrical heating technique no irritating noise is produced and also the radiation loses are negligible.

Want apology from Education Misnister Smiriti Irani

Parliament Logjam over JNU controversy is likely to continue today, the third day of Budget Session. The Congress is resolute on an apology from Education Minister Smiriti Irani for reading out a JNU pamphlet,which had derogatory refrence to Goddess Durga. The main opposion party has said it will not allow the house to functiontill the minister apologises. Latest replies are:

a) Replying during the debate today in Rajya Sabha Smiriti Irani reffered to the documents and said they were authenticated by JNU . "I read it because I asked to explain the truth. I am a practising Hindu, I myself am a Durga Worshipper. I said it with a lot of pain."
b) "There were no comments made on veracity of facts yesterday. The documents I read are official documents from University, these are not the documents of the government". she said amid shouting from opposition benches.
c) "No blasphemous remark will be allowed in the house. What can I do now is I will go through the record and expunge anything that is blasphemous." Deputy chairman PJ Kurien said.

Utilization of Electrical Energy And Traction- Ajax Wyatt Furnance

The Ajax Wyatt Vertical core is shown. It has horizontal iron core similar to three phase transformer. the central core passes through the crucible. heat is generated in the charge by the action of heavy induced current which flows in the channel of molten metal situated between an inductor coil and the furnance lining.

Principle of Operation-

Its principle of operation is similar to the transformer in which secondary turns are replaced by a closed loop of molten metal. the primary is an inductor coil wound on the central limb of the laminated core which concentrates the magnetic field.

Working-
The application of ac at mains frequency to the primary inductor coil causes an intense electromagnetic field to fluctuate in the laminated core. the molten metal in the 'V' portion acts as a short circuited secondary coil carrying induced current. heat mainly generated in the 'V' portion because of its high resistance. Due to small section heat is rapidly distributed to the metal above the inductor by convection and by stirring action of electromagnetic forces. the 'V' portion is alwais kept full of metal.

Since the primary and secondary are both on the same central core, it's power factor is better. Due to its heavyweight there is no chance of pinch effect. therefore we can employ the power frequencies with this type of furnance.
It is used for melting the ferrous metals such as brass, zinc, tin etc.


Utilization of Electrical Energy And Traction- Resistance Heating

The heating method of resistance heating has wide application such as treatment of metals(annealing,hardening etc,) drying and baking of potteries,stoving of enamelled ware and commercial and domestic cooking. Temperature upto 1273K can be achieved by this method.

There are two types of Resistance Heating:

a) Direct Resistance Heating:- In this method the material or charge to be heated is taken as a resistance and current is passed through it. the charge may be in the form f powder, pieces or a liquid. Two electrodes are immersed in the charge and connected to the supply in case of availaibility of three phase supply.  This method has high efficiency. Heat temperature control is not possible in this method.This method is used in salt bath furnance and in the eectrode boiler of heating.

b) Indirect Resistance Heating:- In this method the current is passed through a wire or other high resistance material forming a heating element.The heat produced is directly proportional to the core losses. The heat is transffered by conduction ,convection,radiation processes. if heat is transffered by conduction the resistor must be in contact with the charge. An enclosure known as heating chamber is required for transfer by radiation and convection.
