Heart Attack Symptoms And Early Warning signs

By
A Heart attack is the death of heart muscle due to loss of blood supply. The loss of blood supply is usually caused by a complete blockage of a Coronary Artery, one of the arteries that supplies blood
to heart muscle. Death of the heart muscle, in turn, cause chest pain and electrical instability of the heart muscle tissue. Chest pain or pressure is the most common symptom of a heart attack, however, people who are having a heart attack may experience of a variety of conditions that include Jaw pain, Sweating, Heart burn, Shortness of breath, Toothache, Headache, Nausea and Vomiting. Most of the deaths from heart attacks are caused by ventricular fibrillation of the heart that occurs before the victim of heart attack can reach an emergency room.

Heart attacks are diagnosed with procedures such as Coronary Angiogram and PTCA (Coronary Balloon Angioplasty), and clot dissolving drugs are available that can quickly open blocked arteries
in order to restore circulation to the heart and limit heart muscle damage. In order to optimally
benefit heart attack victims and limit the extent of heart damage, these treatments to open blocked arteries should be given early during heart attack. Blood Pressure is not a reliable measurement of whether one is having a heart attack. Blood pressure during a heart attack can be low, normal or elevated. Drugs that treat heart attacks include for example, Aspirin, Nitroglycerin, Clot busting drugs, Percutaneous coronary intervention, medical procedure, cardiac rehabilitation, oxygen therapy and lifestyle changes.

Sometimes, there is a confusion between the terms "Cardiac arrest" and "Heart attack". A heart
attack or Myocardial infarction, is damage to the heart muscle that occurs due to reduced blood
flow to the heart muscle, depriving the heart muscle of the oxygen it needs to function properly. Cardiac arrest means that heart stops beating and death is imminent. A Heart attack, if severe,
can lead to cardiac arrest and this is what occurs when heart attack is fatal. However, other conditions, such as serious Arrhythmias or shock, can also cause cardiac arrest.

Knowing the early warning signs of heart attack is critical for prompt recognition and treatment.
Many heart attacks starts slowly, unlike the dramatic portrayal often seen in the movies. A person
experiencing heart attack may not even be sure of what is happening. Symptoms vary among individuals and even a person who has had a previous heart attack may have different symptoms in a subsequent heart attack.

Doctor agree that if you are in a doubt, get checked out anyway, even if you are not sure if
something is really wrong. Prompt administration of drugs can help restore circulation to the
heart and increase you chances of survival.

Qualities Of A Good Prime Minister

By
Following are ten qualities (not in order of importance), which I believe are the most important for a Prime Minister and why ? - 1) Ability to connect with constituents - All great leaders in history had a penchant for being able to connect with their citizens i.e. a strong or habitual liking for something or tendency to do something. Leaders who have failed have probably failed in this domain. 2) Clarity of vision - The Prime Minister who knows their vision and can successfully articulate it to the voting public is one who will be held in high regard. 3) Coherent grasp of domestic issues - There has to be a keen desire and understanding of domestic concerns that directly impact the citizens. Failure to understand and address these issues will create a gap between what the Leader does and how it impacts their citizens. 4) Clear understanding of different cultures in their Governance - All good leaders will be able to understand the Political culture, Ethical/ Racial cultures, Cl

Working Of Nuclear Plant and Generation Of Energy

By
Nuclear energy originates from splitting of Uranium atoms- a process called fission. This generates heat to produce steam, which is used by Turbine generator to generate electricity, because Nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions. It is the safe, clean, cost effective alternative contrary to claims by opponents of nuclear energy. Nuclear power reactors use controlled nuclear fission in a chain reaction. With the use of neutron absorbers, the rate of reaction controlled, so the power depends on demand. By reliably providing power 24 hours a day, Nuclear energy is an important part of the energy mix necessary to meet electricity demand. And, with no carbon emissions, it will remain an important clean energy resource for the future. For more than forty years, Duke Energy, USA has operated nuclear plants- setting industry benchmarks for safety and efficiency in the process. Working of a Nuclear Plant - A Nuclear power plant works much like a

The business world today is driven by customer demand. Unfortunately, the demand patterns vary considerably from time to time. That is why it can be so challenging to develop accurate forecasts. The goals of forecasting are to reduce uncertainty & provide benchmarks for monitoring actual performance. A new generation of Artificial Intelligence technologies have emerged that hold significant commitment on improving forecasting process including applications as product demand, employee turnover, cash flow, distribution requirements, manpower forecasting & inventory. Artificial Intelligence systems are designed to bridge the gap between the two traditional forecasting approaches - Managerial and Quantitative. Artificial Intelligence is defined as a Computer Based analytical process exhibiting actions and behavior considered ' Intelligent' by human observers.

Satellite Prediction Of Floods In India

By
Floods are one of the most devastating and costly national disasters each year affecting on an average 96.9 million people worldwide and causing $13.7 Billion in damages according to U.N. Office for Disaster Risk Reduction. They wash away or destroy Homes, Pollute Drinking Water and a source to giving birth to water borne diseases. The Indian sub-continent is one of the most affected due to chronic flood events mostly induced by periodic monsoon rainfall. The North - Eastern state of Assam has a complex fluvial systems of rivers, mainly with two inter connected rivers of Brahmaputra and Barak which together enter Bay of Bengal. Due to enormous sediment transport from the upper catchment areas and subsequent lack of carrying capacity of the channels in these two river valleys, flooding is a periodic phenomenon every year during the peak monsoon months from June to Sept. causing extensive damages to life and property. Satellite plays important role in detection and monitoring of flo

U.S. dollar is strongest currency which supports U.S. economy. The reason is that more than one -third countries of the world's gross domestic product comes from countries that peg their currencies to dollars.

Devaluation and causes for Foreign Exchange rates variation

By
  Indian Rupee and Devaluation  Indian Rupee was settled at Rs.13/- per pound and dollar @ Re.1/-  in 1947 after partition. It continued up to 1966 when first devaluation took place.
