Every object, every particle and every system oscillates in its own natural frequency or set of frequencies. The natural frequency of an object is the frequency at which the object tends to vibrate or oscillate without any external force applied. All these objects and particles require a source of energy at a specific frequency ranging from few Hz to several MHz. This requirement can be fulfilled by an electronic device called an oscillator.

Fractional vs Simple Distillation In chemistry, we are taught how to separate mixtures, and one of the most interesting ways to separate mixtures is through distillation. Distillation is a common method that is often used in separating liquid mixtures, based on the differences in the volatilities of substances. Distillation is a physical process, as it does not rely on any chemical reaction. Distillation is an essential process for many industries – from power generation to beverage production.

Key Difference – Inductive Effect vs Mesomeric Effect   Inductive effect and mesomeric effect are two types of electronic effects in polyatomic molecules. However, inductive effect and mesomeric effect arise due to two different factors. For example, inductive effect is a result of the polarization of σ bonds and mesomeric effect is a result of the substituents or functional groups in a chemical compound. Both mesomeric and inductive effect can exist in some complex molecules.

The key difference between vitamin B3 and B12 is that vitamin B3 is important in controlling cholesterol and triglyceride levels in our blood, whereas vitamin B12 is important as a cofactor in DNA synthesis for both fatty acid and amino acid metabolism. Vitamin B3 is a member of the vitamin family, which includes three forms of vitamers as nicotinamide, niacin, and nicotinamide riboside. Vitamin B12 is a type of vitamin involved in metabolism in our body.

Cachetic Cachexia, or wasting syndrome, is loss of weight, muscle atrophy, fatigue, weakness and significant loss of appetite in someone who is not actively trying to lose weight. Cachexia is seen in people with cancer, AIDS, coeliac disease, chronic obstructive pulmonary disease, multiple sclerosis, rheumatoid arthritis, congestive heart failure, tuberculosis, familial amyloid polyneuropathy, mercury poisoning (acrodynia), Crohn’s disease, untreated/severe type 1 diabetes mellitus, anorexia nervosa and hormonal deficiency.It is a positive risk factor for death, meaning if the person has cachexia, the chance of death from the underlying condition is increased dramatically.
