Precaution measures for earthquake

Earthquakes are natural disasters. We cannot stop it or avoid it but we can make ourselves alert and take some of the measures by which we can overcome the bad effects of the earthquake. This can be done by construction the houses in the wood instead of the bricks .the exit of each of the house should be given high care. There should be at least 2 exits from the house. The proper alert system for the earthquake prone areas should be given

Split squat

The split squat is mainly for the work of the leg muscles, it makes the leg muscles work to the maximum intensity by applying weight of the entire body on the leg. This provides the overall workout of the muscles. Also it helps in the stretching of those muscles. In the split squat the force is applied separately in each of the legs then the other advantage it applies the own body weight instead of using any other dumbbells or barbells.

The Thumb-Up Gesture

The thumb up signal in generally for showing everything is OK.In Greece, it means ‘get stuffed’, so one can imagine the dilemma of the Australian hitch-hiker using this gesture in that country!In Italy people count from one to five, they use this gesture to mean ‘one’ and the index finger then becomes ‘two’. In most other countries the people count the one in the index finger and then two in the middle finger here thumb will represent the number ‘five’.It also represents power and superiority.

Proteins

Genes and proteins are products of evolution. Over the course of evolution, the nucleotide sequences of genes undergo numerous changes. First, duplications (or deletions) may lead to creation of additional copies (or removal) of genes or gene fragments. Second, local mutations: substitutions, insertions and deletions within genes may result in changes to the amino acid sequence of proteins they encode. Thus, the initially identical copies of duplicated genes over time accumulate divergent mutations that make their sequences progressively dissimilar. Not all positions of protein-encoding genes are equally susceptible to mutation, as some amino acid residues may be very important for protein function, stability, or folding and may thus be more constrained in the residue types allowed. Therefore, although mutations are random, in nature we observe only such protein variants, in which sequence changes have been ‘accepted’ by the evolutionary pressure. Proteins with mutations that cause detrimental changes in structure and/or function are usually eliminated. If the protein is important to the integrity of the organism, the organism that bears the mutant gene dies, and the structurally/functionally compromised variant ceases to exist; or if it is not important, then the inactivated gene may be eventually ‘purged’ from the genome by random deletions. On the other hand, if the mutant variant brings an additional and beneficial new function to the organism, it is likely to be retained and further ‘optimized’ towards the activity favored by the selective pressure.

Rest and relaxation

If you plan sightseeing or travel while there, it is often a good idea to do it immediately after the operating period is finished.Leave time at the end of the sightseeing to do another post-operativeward round or outpatient clinic, to see complications and advise further management.This applies especially after you have performed on a condition or used a procedure that is new to you and the national surgeon

You should be aware of the vaccination you are taking it should be new and should be adequate. The care of the malaria and hepatitis B. You must discuss the things which you are going to do with your physicians.

Success is elusive

Students can all too easily be influenced by the hype surrounding exams. Being in the process of defining who they are and what they do, and having very little life experience of their own, they Students tend to adopt the attitudes of those around them. Consequently, discount their success many students set themselves unrealistic targets – or allow such targets to be set for them. As a result, they often feel disappointed in themselves, despite their successes.
