Obesity prevalence over the last three decades has risen markedly and is now affecting approximately 40% of the human population worldwide [1], an incidence that is starkly similar to that of heart disease, stroke and hypertension [2]. Although the main culprit for body fat deposition is the energy surplus, a growing body of evidence points to the apparent role of dietary, or added sugars, in this milieu. It is estimated that approximately 20% of regular western diet consists of added sugars, mainly

temperature need to be adjusted when different material types are used. When required it is possible to mix different materials with different properties to produce a single printed object. By end of this paper one is able to fabricate a 3D printer with low cost. Abstract 3D printers are devices that can create a three-dimensional object from a

Smelting and roasting are classified as pyrometallurgy, which is, the use of heat for the treatment of an ore Heap Leach Process: Low grade gold-bearing ore is mined in an open cut, then crushed and screened. Lime is mixed with the ore to control the pH of the leaching operation. The ore is piled into heaps on polyethylene pads and cyanide solution is sprayed over the heaps. The cyanide dissolves most of the gold as it trickles through the ore, producing a "pregnant" solution

Where does all the plastic go. Every bit of plastic that has been created is still here. This is because plastic is one-hundred percent non-biodegradable! Even the most degraded plastic down to polymers cannot be digested by bacteria (Laist, 1997). If global issues like starvation and climate change are not enough to stress on, the weight of an issue literally churning in the Pacific Ocean is startling. For decades the majority of the world’s population has not been properly educated on the nature

plants are supported in a High density polyethylene (HDPE) trays of varying size, which are then transported to the roofs and installed. Traditional roofs can further be classified as: Extensive, Semi-intensive and Intensive (Wark and Wark, 2003). Extensive roofs are of low profile and performance, which are designed for maximum thermal and hydrological performance and minimum weight load. They contain low profiles of 6 inches or less, with smaller plant diversity and low access for active human use

include: Low density Low water vapour transpiration rate Good Stiffness Resistance to cracking High tensile strength Heat seal ability Polypropylene may be used for shrink wrapping or heating in bags. Polyester: polyester belongs to the class of condensation polymers which is formed by eliminating a small molecule usually, water from two different reactants leaving binding sites which enable two reactants to join together into long chains. The most important polyester in packaging is polyethylene terphthalate

disaster can be avoided. One approach is to have professionals in the related field expose such technologies that people believe are helping them but instead are causing damage to the environment. As a previous low voltage linemen with seven years of experience, alongside my father who has been a low voltage linemen for twenty plus years, one tool that must be
