Isotopes of carbon

MANUFACTURING COSTS: Functional Elements: The baby stroller is mainly composed of three materials: Nylon (woven, as fabric) Plastic (injection molded, for plastic parts) Steel (tubing, for frame) Fasteners are included in the assembly of different components of the strollers. The stroller would have to be manufactured on an assembly line. The fabric weaving and seat making, the plastic molding and the frame can simultaneously be manufactured in their respective work areas. Following are…

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.…

Carbohydrates have the following basic composition. They are molecular compounds made from three elements: carbon, hydrogen and oxygen. Monosaccharides are simple sugars with multiple OH groups. Based on number of carbons 3, 4, 5, 6, a monosaccharide is a triose, tetrose, pentose or hexose respectively. Disaccharides are condensation products of two monosaccharide units; examples are maltose and sucrose. A disaccharide is 2 monosaccharides covalently linked molecule. Polysaccharides are polymers…

DISCUSSION The term “elastomer” refers to any member of a class of polymeric materials with the ability to regain shape after deformation.27, i The very first common elastomer was natural rubber. There were used by the Maya and Inca civilizations. With the introduction of vulcanization, by Charles Goodyear in the year 1839, the physical properties of rubbers were improved, considerably enhancing its use.27 In the 1920’s, manufacture of synthetic rubber bands were started by the petrochemical…

2.4.1 Magnesium Properties Magnesium is the essential to human body and naturally it is found in bone and it is the fourth cation in human body. Magnesium is a lightweight metal with a density of 1.74 g/cm3. The fracture toughness of magnesium are greater than the ceramic materials such as hydroxyapatite. Elastic modulus and compressive yield strength of magnesium are similarly to human bone. The disadvantages of magnesium is it has low corrosion resistance and stimulatory effects on the growth…

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…
