FIBER REINFORCED PLASTICS

Friday, August 28th, 2009

Fiber Reinforced Plastics (FRP) plays a very important role in the machine industry. FRP is generally a composite material. Composite materials are the one that has got improved properties and also they are developed in such a way to get the desired properties.

FRP has the properties of high strength, high modulus, greater heat resistance and light weight. For these properties they are used in many machine parts. The reinforced plastic has got fiberous glass in the form of mats, rovings and chopped strands. Vinyl silane-epoxy surface treatment is carried out on the fibers to improve their wet and dry strength, thereby increasing their tensile strength to withstand heavy loads.

Here plastics are mostly made of polyster resin and also other resins like epoxy and phenolic resins are also used. Boric acid is used as one of the melt rather than soda ash in the case of E type glass, one of the important glass fiber materials. In motor car bodies, sinks, chemical vats, etc., glass reinforced plastics are used as glass provides strength and the polymer reduces the brittleness. Synthetic textile fibers are treated in such a way to get the desired fibers.

Carbon fiber reinforced plastics has lower density and greater resistance, hence they are used in aero engines, high pressure rotor and stator blades. Silica and Boron fiber reinforced plastics have the same properties of high strength and low density. But Carbon fiber reinforced plastics are preferred over Silica and Boron fiber reinforced plastics because they are cheap.

HEALTHY LIFESTYLE

Tuesday, August 25th, 2009

        Good health can be maintained by proper nutritional and healthy food. A balanced diet is essential to live a healthy life. Good food habits and regular exercise will keep our body in good condition with the right posture. Healthy food involves taking the right food at the right time. Things cannot happen overnight to become fit, slim and healthy. This can be achieved only on a regular basis with proper diet and exercise. Your exercise can be jogging, walking, swimming and some other outdoor games like playing badminton, tennis, etc ., or else you can even work out in a gym, though not to build your body but to keep it fit enough.

                Good night sleep is a must to be free from stress and also keep our body fit. At least six to eight hours sleep is necessary for an adult in a day. The main thing to get a nice sleep is to keep away the stress. Stress gets developed due to heavy working hours, strain and also keeps on thinking about an issue or a problem. Stress will cause headache and restlessness. Taking deep breaths and a small walk during stress will keep the tension off the sight.

Some tips for eating: add starchy foods and vegetables in your regular food habits, take enough protein rich content foods, avoid using lots of sugar but use it, eat at least 3 times a day, try to quit the practice of smoking and drinking alcohol and also do not involve in fasting unless it is mandatory.

Earth Fever

Thursday, August 20th, 2009

Earths temperature is increasing day by day mainly because of us. Technologies also pose a heavy threat to earth. There are many disastrous effects taking place in the earth’s atmosphere. Global warming takes place because of Green house gases. The gases from vehicles, factories, and chemical industries get accumulated in the earth’s atmosphere boosts global warming.

Refrigerators emit CFC which increases the earth’s temperature. It reflects back the heat into the earth which is known as green house effect. The result of this is the depletion in the ozone layer. The hole in the ozone layer is the dead end for earth.

The effects of global warming results in the increase in ocean level, melting of ice bergs, reduction in the flora and fauna. Monsoons are getting delayed because of this warming. The ozone layer depletion leads to the direct path of sun rays. The ultra violet radiation from sun’s rays leads to skin diseases. We can’t come out without covering our entire body.

The new diseases entering into the world is mainly because of these global warming. Fires and drought are due to this warming. It can’t be completely eradicated. Planting trees must be encouraged. Plants and trees absorb these harmful gases. So it would be better to encourage the planting of trees.

The chemicals coming out from the industries must be recycled and filtered. Air pollution and Water pollution should be reduced to certain extent in the forthcoming days. Emerging technologies must be eco friendly. Every product born on this earth must be environmental friendly. It is the sole responsibility of each individual to fight against the global warming.

Babies value the Dogs

Monday, August 10th, 2009

        The young infants sometimes understand the pet’s language. The new born babies value the barks of the dogs.  Even though they don’t have a different exposure to pet animals they can differentiate the sounds. As we all know babies watch all the things in and around them. It is the usual habit of young babies to respond to these dissimilar sounds. Both the sound of the infants and dogs looks silly but a study clearly pictured the response of babies to different sounds. It is published in the Development Psychology weekly which shows that babies have the capability to value the sounds of dogs. In a research from Brigham Young University revealed that even the six month old infants can distinguish the angry and the happy body languages.

                                Babies have the habit to recognize the things around them but they will find it difficult to adapt to the new environment. They have the sharp grasping capability. If the mother feeds the infants with enough knowledge, the infant will develop into a talented individual.  The researchers made an attempt to identify the emotions and the responses of the child. They chose the pet animal as the dog as it is mans best friend. In that attempt they showed two pictures one is rude and the other a friendly look. Then they played the barking tones related to the pictures. They recognized the tone and looked at the picture till the sound ends. That predicts the baby’s capability to differentiate the things.
