Dietary Fiber Dietary Fiber is the parts of plant that resist digestive enzymes. A few definitions of dietary fibers are nondigestible carbohydrates and lignin that are intrinsic and intact in plants. nondigestible carbohydrates and lignin that are intact in plants. Another definition is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine‚ with complete or partial fermentation in the large intestine.

Synthetic polymers offer more possibilities‚ since they can be designed with molecular structures that impart properties for desired end uses. All fibers are ploy-something or polymers. That means they are long strings of repeating chemical elements. Some fibers come from ground plants that synthesize connected units of cellulose

Fiber Optics History of Fiber Optics History Of Fiber Optics In 1870‚ John Tyndall‚ using a jet of water that flowed from one container to another and a beam of light‚ demonstrated that light used internal reflection to follow a specific path. • Alexander Graham Bell patented an optical telephone system‚ which he called the Photophone • He dreamed of sending signals through the air‚ but the atmosphere didn’t transmit light as reliably as wires carried electricity. • During the 1920s‚ John

Fiber optics is a cable that is quickly replacing out-dated copper wires. Fiber optics is based on a concept known as total internal reflection. It can transmit video‚ sound‚ or data in either analog or digital form . Compared to copper wires it can transmit thousands of times more data (slide 2) . Some of its general uses are telecommunications‚ computing‚ and medicine. <br> <br>The very first "fiber" was made in 1870 by the British physicist John Tyndal. In this experiment that he showed to the

Do transgenic crops (Genetically Modified) pose an unacceptable threat to the environment and the maintenance of biodiversity or are they a necessary response to meeting the twin challenges of climate change and sustainability? The population of the world is predicted to reach 19.9 billion by 2025 (United Nations Population Information Network‚ 2011). According to Purchase (2005)‚ this increase in population will bring along with it the problem of food security. The priority for the world

CROP INSURANCE: A Tool to save Farmers from Calamities EXECUTIVE SUMMARY Crop insurance is one of the various types of insurance that are offered to the people. This insurance is directed to the farmers and agriculturists. This Crop insurance scheme has been going on since the time of Kharif 1985. This insurance offers financial assistance for risk management in agriculture. This insurance policy is a relief scheme for the farmers whose crops get spoiled during natural catastrophe. The

Matho-Geometry Project The Geometry of Crop Circles INTRODUCTION A crop circle is an area in a field of crops where the plants have been mysteriously flattened into the shape of a circle or a more complex pattern. A crop circle is a sizable pattern created by the flattening of a crop such as wheat‚ barley‚ rye‚ maize‚ or rapeseed. Crop circles are also referred to as crop formations‚ because they are not always circular in shape. The documented cases have substantially increased from the 1970s

Fill in the boxes below to explain how each step led many farmers to leave their farms for a life in the city. (7 points) Cash Crops In the late 1800’s the majority of farmers grew enough food to support themselves‚ with a small percentage of product for sale to others‚ and the farmers were making profit. A much higher production drove down the price‚ which had the effect of making
