We found 12 results that contain "fast"

They were wrong. It soon became obvious that employees, less than engaged, were more likely to roll their eyes than roll up their sleeves when the new change requirements were explained to them. "Change fatigue" was ubiquitous. After all, the current effort was just the latest in a long string of change efforts—few of which had succeeded.
Even more worrisome: proof of resistance was everywhere, confidence in the company's senior management was low, and there was little clarity concerning the factors by which employees were measured. Long story short: the changes went nowhere fast. In that respect, the energy company was no different from the myriads of other organizations that fail to do a proper job of delivering transformational changes.
Today, the company's story is quite different. The targeted savings have been achieved—and are being sustained. Many of the company's functions are cost-effective, thanks largely to motivated in-house teams of line managers. The key initiatives are explicitly defined and owned, and managers know which milestones the organization must achieve and when, as well as which course corrections they must make if a milestone is likely to be missed.

 Hemoglobin is an iron-rich protein in red blood cells (RBCs).   The normal hemoglobin range for men is 13.5 to 17.5 gm/dL and 12 to 15.5 gm/dL for women. It is of utmost importance to maintain hemoglobin concentration.

What functions does hemoglobin perform in our bodies? 
Hemoglobin is vital for carrying oxygen from the lungs to tissues and organs. It also transports carbon dioxide from the tissues back to the lungs.
What causes low hemoglobin?

Some common causes of low hemoglobin are:

Substantial blood loss
Deficiency in iron, vitamin B, and folate
Kidney disease
Hypothyroidism
Thalassemia
Lung diseases
Excessive smoking

Any type of blood loss can cause anemia, including blood loss from surgery, heavy menstrual periods, and bleeding in the gastrointestinal tract. 
Symptoms of low hemoglobin
You can detect extremely low hemoglobin levels in your system in a few ways. They include

A fast or irregular heartbeat
Fatigue
Frequent or unexplained bruising
Shortness of breath
Liver and kidney disease
Pale skin and gums
Muscle weakness
Reoccurring headaches
Dizziness
Poor appetite
Anemia in severe cases

Elevated hemoglobin levels are associated with dehydration, heart failure, and chronic lung disease. In some conditions, the bone marrow may not produce enough RBCs, leading to cancers like leukemia, lymphoma, or tumors that spread from other parts of the body into the bone marrow.
What are the foods that can improve your hemoglobin levels?

It is essential to boost your food intake to raise your hemoglobin levels. Here are some foods to increase hemoglobin levels:

Iron-rich foods: Consume iron-rich foods like fish, meat, eggs, soy products, broccoli, green leafy vegetables that include spinach, fenugreek leaves, cauliflower, green peas, cabbage, green beans, nuts and seeds, and peanut butter, to increase your hemoglobin levels.
Vitamin A: It is pertinent to consume vitamin A foods to increase hemoglobin as they absorb more iron. Vitamin A and beta-carotene can help you there. Vitamin A is found in animal food sources, such as fish and liver. Beta-carotene is found in red, yellow, and orange fruits and vegetables.
Folate: Folate is a type of Vitamin B that plays an essential part in hemoglobin production. A shortage of folate can prevent the red blood cells from maturing, leading to anemia. Some good sources of folate include beef, rice, black-eyed peas, kidney beans, lettuce, and peanuts.
Foods rich in vitamin C: A combination of iron and vitamin C can prove to be beneficial. The latter is used for better absorption of iron. Foods rich in vitamin C include oranges, lemon, strawberries, papaya, bell peppers, broccoli, and tomatoes.
Fruits: It is also perfect to have fruits like beetroot, apple, watermelon, papaya, oranges, litchis, kiwis, strawberries, grapefruit, banana, and peach, which can boost hemoglobin levels. Plus, dry fruits, like dates, can increase the number of erythrocytes, thereby increasing hemoglobin levels. They contain iron, vitamin C, vitamin B complex, and folic acid, which helps in the formation of red blood cells. Raisins are also a rich source of iron and copper necessary to form red blood cells.

Avoid iron blockers: Foods that block your body’s ability to absorb iron, such as coffee, tea, alcohol, and aerated drinks, should be avoided.
Tips to increase your hemoglobin levels
Here are some tips to keep in mind to increase your hemoglobin levels:
Switch to brown rice: As a superfood, brown rice can help prevent various diseases related to cholesterol and the gastrointestinal system. It is rich in iron, containing 0.52 milligrams of iron for every 100 grams.
Enjoy dark chocolate: With over 80% of cocoa, dark chocolate naturally improves hemoglobin levels. Plus, it is loaded with minerals, nutrients and antioxidants.
Drink nettle tea: The spice nettle has also proven to be a good source of iron and vitamin B and C. They can also play a part in increasing hemoglobin levels.
 Exercise: Take up moderate to high-intensity exercise to help your body produce more hemoglobin to meet the oxygen demands of your body.

Before spectroscopic analysis (IR, NMR) became commonplace in the organic chemistry lab, chemical tests were heavily relied upon to support compound identification. A chemical test is typically a fast reaction performed in a test tube that gives a dramatic visual clue (a color change, precipitate, or gas formation) as evidence for a chemical reaction. For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). This is considered a "positive" test result, and in this case indicates the presence of a functional group that can be oxidized (alcohol or aldehyde). A negative test result is retention of the original color of the reagent, in this case the orange color

Symptoms of a heart attack vary. Some people have mild symptoms. Others have severe symptoms. Some people have no symptoms.
Common heart attack symptoms include:

Chest pain that may feel like pressure, tightness, pain, squeezing or aching
Pain or discomfort that spreads to the shoulder, arm, back, neck, jaw, teeth or sometimes the upper belly
Cold sweat
Fatigue
Heartburn or indigestion
Lightheadedness or sudden dizziness
Nausea
Shortness of breath

Women may have atypical symptoms such as brief or sharp pain felt in the neck, arm or back. Sometimes, the first symptom sign of a heart attack is sudden cardiac arrest.
Some heart attacks strike suddenly. But many people have warning signs and symptoms hours, days or weeks in advance. Chest pain or pressure (angina) that keeps happening and doesn't go away with rest may be an early warning sign. Angina is caused by a temporary decrease in blood flow to the heart.



When to see a doctor





Get help right away if you think you're having a heart attack. Take these steps:

Call for emergency medical help. If you think you're having a heart attack, immediately call 911 or your local emergency number. If you don't have access to emergency medical services, have someone drive you to the nearest hospital. Drive yourself only if there are no other options.
Take nitroglycerin, if prescribed to you by a health care provider. Take it as instructed while awaiting emergency help.

Take aspirin, if recommended. Taking aspirin during a heart attack may reduce heart damage by preventing blood clotting.
Aspirin can interact with other drugs. Don't take an aspirin unless your care provider or emergency medical personnel say to do so. Don't delay calling 911 to take an aspirin. Call for emergency help first.






What to do if you see someone who might be having a heart attack
If someone is unconscious and you think they're having a heart attack, first call 911 or your local emergency number. Then check if the person is breathing and has a pulse. If the person isn't breathing or you don't find a pulse, only then should you begin cardiopulmonary resuscitation (CPR).

If you're untrained in CPR, do hands-only CPR. That means push hard and fast on the person's chest — about 100 to 120 compressions a minute.
If you're trained in CPR and confident in your ability, start with 30 chest compressions before giving two rescue breaths.
