Due to hartal...the students of HSC examinees are getting  tension..
As their scheduled exam are not held as a result good preparation are someway weakened....and causes mental disturbances...

What should our nation do?

What should be the ri8 solution?

during strike two parts of the society get the most hampered: Students and Patients. Students have their exam next month. But the syllabus is still yet to be finished. They are just waiting for when their make up classes will be held. Even the teachers are running back and through to look for their schedules to cover the make up classes.

It is observed by the medical world that after the age 60 years, the heart and liver start functioning slower and slower. As such, rest after meals is most necessary. And a change in diet is a must. Try to reduce cooked food as much as possible. Increase the intake of green juices, fruit juices, green salads, fruits and yoghurt, etc. which are easily digestible and which will give you enough energy. Moreover, light exercise, walking/ swimming for 40 minutes are must. Very soon you will be near nature and every morning will bring you new joys and new meaning of life. And you will feel young, sing merrily like a bird and will feel confident, of living for 100 years

It seems ...our country politics are taking a new dimension due to the ongoing strike/long -march performed by hepajat a  Islam....

What is gonna be happen?  Let us stay in safe and sound.....our request to gr8 politicians........

DIU students are no doubt, comparatively better in computer knowledge....

As DIU is IT based university...So the student are much fascinated  in IT and computer learning

A soft, sueded finish resulting from sanding or chemical treatment of the fabric.
Peach skin is a smooth finish applied to finely woven Micro Fiber fabric. This finish allows suits and dresses to flow with your movements and drape beautifully. Peach Skin fabric suits and dresses are ideal for any season and weather due to its light weight and texture. Peach skin is not too heavy nor too hot which makes it perfect for any season. The feel of this luxurious fabric is soft, smooth and moderately wrinkle-resistant. Wrinkles fall out by simply hanging the ensemble.
Style Magazine says “once you wear a Peach Skin suit, you will never want to take it off.”

Quaternary Ammonium Salts

Apparel/Sportswear/leisurewear/workwear: to get rid of the bad odour  produced by the bacterial decomposition of sweat and other body fluids.

Undergarments (including underwear worn by astronauts): to control the growth of bacteria which thrive on suitable body temperature and moisture conditions, leading to skin diseases

Socks: to make them free from unpleasant odour by controlling the growth of microbes.

Shoes: to avoid shoe odour and the stains on the shoelaces caused by bacterial growth, especially in rainy season.

Home Furnishings and Upholstery: to inhibit the growth of bacteria leading to degradation and/or staining in carpets , shower curtains, mattress ticking, pillow covers, pillow fills and

Industrial Fabrics Exposed to Weather: to protect fabrics used for awnings, tents,

tarpaulins and the like from rotting and mildew.

Sized Fabrics: to protect microbial growth due to the presence of warp size.

Wet Textiles: to prevent degradation of fabrics by microbial attack during prolong storage between processing steps.

Medical Textiles: to impart antimicrobial properties on wound dressings  and get freedom from microbes/pathogens from textiles used in hospitals, nursing homes, medical and research facilities, and veterinary clinics for protection against infectious diseases.

Textiles in Museums: to preserve textile monuments from microbial attack.

1)    Protection of the raw material from decay or degradation
2)    Control of staining caused by microbial growth
3)    Added freshness to the fabrics
4)    Elimination of smells created by microorganisms
5)    Increased life period of the fabric because of control of the growth of microbes
6)    Improvement in the handle for most of the fabrics
7)    No irritation of the skin and no physiologic impact to human health

Although microbes can be useful in many ways, for example in brewing, baking and biotechnology, they can also be harmful to both textiles and humans. Different substances added to textiles, such as size, hand modifiers, antistats, thickeners, lubricants and dirt as well as grease, sweat and dead skin from the human body provide a great source of nourishment for microorganisms. Following are some of the possible effects of micro-organisms on textiles:

1)    Bad odour
2)   Discoloration, unsightliness  or staining of the fabric
3)      A slick slimy handle
4)      Loss of functional properties like elasticity and tensile strength
5)      Decrease in the life of the textiles, especially cotton and wool 

Natural fibres are particularly prone to microbial attack as they are readily digestible by bacteria and fungi but the synthetic fibres are not completely immune either as they might contain some additives that may be a nutrient for microbes .Wool is more likely to be attacked by bacteria than cotton while cotton is more likely to be attacked than wool by fungi. Many different finishes
applied on textiles are excellent source of nutrients for microbes, making textiles susceptible to microbial attack. Work in progress in textile manufacturing is also susceptible to microbial attack, particularly if the goods are left for a long time in conditions conducive for microbial growth. Apart from their effects on textiles, microbes can be a source of many problems to human beings, ranging from simple unpleasant odour to physical irritation, allergy, toxic responses, infection and diseases.   An unpleasant odour results when, among other things, human
perspiration is converted by bacteria into foul-smelling substances such as aldehydes, amines, ammonia, sulphides, mercaptans, aromatics, lactones and fatty acids (acetic, propionic, butyric, valerianic, caproic). The minute particles of house dust mite excrements adhering to dust particles can cause dust allergies while mould fungi of the aspergillus type can produce lung disease
