compelling force of nature once more; Jute bags. Natural fibers s will assume a key part in the developing "green" economy in light of energy efficiency, the utilization of renewable encourage stocks in polymer items, modern procedures that decrease carbon discharges and recyclable materials that limit waste. Natural fibres are a sustainable asset, second to none – they have been revived by nature and human ingenuity for…

1.Bi Metallic bearings Steelair’s bimetallic bearing represents advancement in bearing technology and it can be assembled, accustomed or soldered into place. Along with high load capacity and good fatigue properties, it is also an excellent wear-resistant material. The bimetallic bearing is the composite of low friction copper alloy and is perfect for use when provided with excellent requisite strength and the finest carrying capacity by means of derived remains and secondary wedging technology.…

v Elastomeric chains are polyurethanes, possessing low molecular weight polymers, usually either polyether or polyester, they form a complex structure by urethane linkage. iv, vi Polyurethane polymers possess rubber like elasticity and have long chains, lightly cross linked structures with a weak molecular attraction consisting of primary and secondary bonds. 27 Prior to stretching, elastomeric chain consists of folded linear molecular chains. Upon extension, these Molecular chains unfold in an…

haemostatic. The collagen are classified based on their molecules sequences where 27 distinct type with least 42 polypeptide chains of collagen. Mostly, the collagen that present in connective tissues is type 1 which are composed of two α1(1) chains and one α2(1) chain in the form of a triple helix pattern with fiber diameter of about 50nm. Collagen are composed of three polypeptide chains (α…

Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such…

Chemistry Task 2 Portfolio Outline and examine some uses of different metals through history, including contemporary uses, as uncombined metals or as alloys. Metal/Metal Alloy Uses Throughout History Copper - Used to make ornaments and domestic utensils in historical times (not as tools as it is a soft metal) - In modern times used in electrical wiring, pipes and plumbing fittings, jewellery, decoration, - This is due to its malleability, ductility and good electrical conductivity. Bronze…

Leather shooting bags are designed to carry shooting accessories, specialist items, bearing loads comfortably while leaving the shooter's hands free. They provide quick access to the weapon, scopes, and ammunition. Modern day shooting bags have compartments ensuring that everything required is handy. Some bags have been designed in a way that the shooting bag swivels from back to front making the gear more accessible, especially when on the move. While leather shooting bags come in a wide range…

This time I will tell you about two boots which can become your choice that is Rocky S2V and Nike Special Field Boot. Design The upper…

Calibration 1: Text Cyclohexane is a six carbon cyclic alkane that is unusually stable compared to other cyclic alkanes. This stability can be seen by examining cyclohexane in its chair conformation. Since cyclohexane consists of all sp3 hybridized carbons, it ideally exists with 109.5-degree bond angles. If cyclohexane were planar, it would be forced to have 120-degree angels, and would therefore have angle strain. However, cyclohexane chair conformations are almost completely free of angle…

Lithium is an element with the atomic number 3 on the periodic table. Its atomic symbol is Li. Lithium belongs in the most reactive group on the periodic table which is called alkali metal. Lithium under standard conditions is the lightest metal it is also one of the least dense solids. Lithium has an atomic mass of 6.94 and density of 0.534. Lithium is a soft silver white looking metal. Lithium melts at 357 degrees and boils at a temper of 2426 degrees. Thanks to lithium's ability to reach…
