6. (a) Bioresorbable suture thread is produced by spinning raw solution of monofilament or a multifilament known as chitin. Structurally chitin is a N-acetyl glucosamine homopolymer with β-(1,4), yeast, fungi, insects and marine invertebrates. But commercially chitin is produced by shellfish through chemical treatment.

Basically, stability, stiffness and flexibility is provided by chitin to organism. Chitin is perceived by the body to be a foreign material and so our body responds to eliminate it. In our body there is an enzyme named chitanase which helps to break up chitin. Hydrolysis helps in sepration of the individual chitin molecules from each other. Chitin and its derivatives can be used in the care of burn-patients, that one of the most important things. Chitin has exceptional tissue stability and its potential to enhance wound healing was investigated. The topic of chitin is still exciting medical studies.

(b) Often chitin used as a food thickener and stabiliser, and moreover it can also produce edible films.

Q: Two surgical procedures are widely used to treat a certain type of cancer. To compare the success rates of the two procedures, random samples of the two types of surgical patients were obtained and the numbers of patients who showed no recurrence of the disease after a 1-year period were recorded. The data are shown in the table. A test at the 0.05 level of significance is conducted to test whether there is a difference in the success rates...

It is known that the thread life of a certain type of tire has a normal distribution with standard deviation of 1500. a) A sample of 16 tires is found to have an average thread life of 30960. Does this provide sufficient evidence at 1% level of significance to conclude that the true average thread life of this type of tires is more than 30000? Explain by carrying out an appropriate hypothesis test stating clearly the hypotheses. b) What is...

In economics, we usually think of capital as physical assets used to produce goods or services (for example, machinery or factories). But humans also earn capital when they pursue education or training that increases their employability and makes them more valuable to employers. In this week’s video, Nicole Lapin shared her insight into recognizing your own value in the world. Describing a situation where you (or someone you know) has used their problem solving or agility skills to increase their...
