cardiac muscle is considered to be autorhythmic or intrinsically controlled. The cells of cardiac muscle tissue are striated—that is‚ they appear to have light and dark stripes when viewed under a light microscope. The arrangement of protein fibers inside of the cells causes these light and dark bands. Striations indicate that a muscle cell is very strong‚ unlike visceral muscles. The cells of cardiac muscle are branched X or Y shaped cells tightly connected together by special junctions

1. The total amount of fiber that I consumed for the day was 39 grams. 2. The total amount of fiber recommended for my age group according to (Williams & Wilkins‚ 2013) is thirty-eight grams. I happened to be one gram above the fiber recommended daily intake for the age group of 19-50 years of age. 3. To increase an individual’s fiber intake I highly recommend simply replacing refined with whole grain products. One tip on getting more fiber into your daily diet is to try getting

Ganesh Soni 2 What is a composite Material? • Two or more chemically distinct materials combined to have improved properties – Natural/synthetic – Wood is a natural composite of cellulose fiber and lignin. • Cellulose provides strength and the lignin is the "glue" that bonds and stabilizes the fiber. • Bamboo is a wood with hollow cylindrical shape which results in a very light yet stiff structure. Composite fishing poles and golf club shafts copy this design. – The ancient Egyptians manufactured

consisted of thick-walled fibers and vessels‚ similar to fiber-reinforced-matrix composite material. Bamboo fibers are parallel to the axis of internode culm‚ and more concentrated at the upper part of culm and towards the outer layer of the cross section of wall-thickness. As a result‚ bamboo possesses the optimum capacity for load bearing. Mechanical properties of bamboo The mechanical properties of culm depend on the bamboo fiber distribution and orientation‚ since the fibers are mainly responsible

H2O Background Rayon is a synthetic fiber produced from cellulose. Developed in an attempt to produce silk chemically‚ it was originally called artificial silk or wood silk. Rayon is a regenerated fiber‚ because cellulose is converted to a liquid compound and then back to cellulose in the form of fiber. For example‚ cuprammonium rayon is made by dissolving cellulose in an ammoniacal copper sulphate solution. The characteristics of rayon fibers are: s They are highly absorbent‚
