Quality Assurance

In process quality assurance (IPQA) is a crucial aspect of ensuring high-quality products and services in manufacturing organizations. It involves monitoring and controlling various production processes to identify any defects or abnormalities at the earliest stages, with the goal of mitigating risks and minimizing rework or customer dissatisfaction. Gradually becoming an integral part of the overall quality management system, IPQA enables organizations to maintain consistency, improve efficiency, and sustain a competitive edge in the ever-evolving marketplace.

One of the key principles of IPQA is proactive monitoring and control. By implementing this approach, organizations can detect quality issues before they become significant problems, reducing the chances of defective products reaching the customers. This includes regularly inspecting raw materials, components, and equipment, as well as monitoring process parameters such as temperature, pressure, and humidity during production. Implementing robust inspection protocols and utilizing advanced quality control tools like statistical process control can aid in identifying any deviations from the desired specifications.

IPQA also emphasizes the importance of timely corrective actions. When deviations or defects are detected, immediate actions are taken to rectify the issue at hand. This might involve adjusting production parameters, recalibrating equipment, or removing defective components from the production line. The swift response to quality issues minimizes the accumulation of defective products, thereby reducing wastage of time, resources, and materials. It also ensures that products conform to the required quality standards and satisfies customer expectations.

Moreover, IPQA places significant emphasis on error-proofing or mistake-proofing manufacturing processes. Organizations employ various techniques, such as poka-yoke or foolproofing devices, to prevent errors during production. These devices are designed to detect and prevent potential mistakes, like wrong part insertion or incorrect assembly. By implementing error-proofing mechanisms, organizations can reduce the occurrence of defects, thereby improving overall process efficiency and minimizing rework.

SOME BIOCHEMICAL BENEFIT OF CHICKEN
Chicken has well-documented health benefits, but different parts and preparation methods factor into how healthy your chicken-based meal turns out. Darker cuts like the thigh and drumstick contain higher caloric content than lighter cuts like the breast. Keeping the skin or frying chicken will also add saturated fat.
The lean protein in chicken is an excellent source of amino acids. Our bodies use amino acids to build muscle tissue, something that is particularly important as we age. Studies have also shown that higher protein intake helps to maintain bone mineral density. Eating chicken can help to build stronger muscles and promote healthier bones, decreasing the risk of injuries and diseases such as osteoporosis.
Research suggests that 25-30 grams of protein per meal can help us feel more full. Protein rich meals can make us feel fuller despite us eating less, which helps to promote better weight management. Healthier weight leads to improvements in risk factors for heart problems such as high triglyceride levels and high blood pressure. A food rich in protein, chicken can help with weight management and reduce the risk of heart disease.
Chicken contains the amino acid tryptophan, which has been linked to higher levels of serotonin (the “feel good” hormone) in our brains. The tryptophan levels in chicken aren’t high enough to make you feel instantly euphoric, but studies show it could help to boost serotonin levels when paired with other factors.
Nutrition
Chicken is filled with high-quality proteins and doesn’t contain much fat — especially if you eat lean cuts. Beyond its rich protein content, chicken also contains:
• Vitamin B12
• Tryptophan
• Choline
• Zinc
• Iron
• Copper
A raw, boneless skinless chicken breast fillet contains:
• Calories: 120
• Protein: 26 grams
• Fat: 2 grams
• Carbohydrates: 0 grams
• Fiber: 0 grams
• Sugar: 0 grams
• Nutrient composition of some raw and cooked (roasted) cuts of chicken meata

Before the discovery of insulin, people with diabetes didn’t live for long because there wasn’t much doctors could do for them. By 1920 scientists knew that diabetes was due to a lack of insulin formed in parts of the pancreas called islets, but attempts made to extract insulin from pancreatic cells had all failed.

However a surgeon called Frederick Banting suggested a different way to isolate insulin. He met with scientist John Macleod to formulate a plan.

Together Banting and his research assistant, Charles Best, began to experiment. In 1921 they successfully isolated insulin from a dog’s pancreas. The next step was to treat diabetes with their extract. Their experiments were first met with failure, but by November 1921 they had successfully kept a dog with diabetes with their insulin extract for 70 days. In December 1921, the three had biochemist James Collip join their team with the goal of purifying insulin extract and making it more concentrated.

In January 1922, the first person received an insulin injection. Fourteen-year-old Leonard Thompson's high blood sugar levels had dropped, but he still had high levels of ketones.

After Thompson's first injection, Collip worked to purify the insulin extract. Thompson received his second injection on January 23. This time, Thompson's blood sugar levels became near-normal.

In January 1923 Banting, Collip and Best received the American patents on insulin and its creation process. The three sold their patents to the University of Toronto for 1 USD.

According to Banting: “Insulin does not belong to me, it belongs to the world.”

Eli Lilly become the first manufacturer to mass produce insulin and the first commercial supply of insulin was distributed in late 1923.

Banting and Macleod received the 1923 Nobel Prize in Physiology or Medicine. Banting split his half of the prize money with Best, and Macleod split the other half of the prize money with Collip.

Biochemical Reasoning

The organs were in their usual position carrying out their function when smoke passed through the trachea and entered the lungs.

The lungs released the smoke into the bloodstream and affected other organs.

Liver: okay, I'm tired of this nonsense. I'm the only one working so hard in this house, and lungs couldn't do a thing.

Kidney: but he is the one supplying us with oxygen

Liver: so?

Kidney: what is your problem? What do you do in this house, if I may ask?

Liver: oh! Really? I clean up the mess in the stomach and small intestine every time, activate enzymes and store glycogen, vitamins, and minerals. I break and build up proteins, carbohydrates, and fats. I remove dead red blood cells and toxins from this house. You, What do you do?

Kidney: are we going to go down that lane right now? I balance almost everything in this house, including acid-base, water, and electrolytes, and I produce the hormone erythropoietin. I remove toxins and the waste product of nonsense you metabolize. I control blood pressure and activate Vitamin D.

Liver: LMAO! You did all of these for yourself. If not, you would have died a long time ago. You don't even store the vitamin D you produce. Without me, this house would have fallen a long time ago.

Kidney: is that what you think? The erythropoietin I produce helps to stimulate blood from bone marrow, and you can't survive without blood.

Liver: yen yen yen

Kidney: you think we don't know your little secret?

Liver: which is?

Kidney: you hate alcohol that always comes in through the mouth every morning and night. So, you release the enzyme - alcohol dehydrogenase that breaks it down into a substance that causes even more damage to your cell.

The argument was still going on between them when the heart interfered.

Heart: Uhm! Guys!

Liver and kidney: what??????

Heart: I'm getting weak. I think I just got stabbed
