retailing purposed is packaged in refillable glass bottles (Khetarpaul & Punia, 2012, p.142). However, the packages of fluid milk have been changed to single-serve standard/waxed paperboard cartons, plastic containers of various compositions and polyethylene (PE)-coated pouches in today’s market (Robertson, 2012, p.514). It is dependent on the type of materials that the packages can reduce the impact of the light-induced deterioration of milk quality and flavour. Also, the use of pigments, or colours

mechanical properties, crosslinking agents I. Introduction Thermosets are commodity as well as engineering plastics. They account for more than 70% of the total plastics market share. Though they are easily processable and available at relatively low cost, they involve cross linking process (curing) so as to become suitable for the application. There are certain disadvantages associated with processing of thermoset category of plastics like high amount of flashes, mold material abrasion at relatively

due to the cartoneros’ limited funds, there are few choices for available materials. Due to the plight of unemployment in Argentina (Trading economics, 2014), with 7.1 percent unemployment (19 May 2014), the market price of the product needs to be low enough to motivate the locals’ demand and consumption. Environmental Constraints Environmental awareness and conservation of the environment are factors that must be considered. According to the research from the Food and Agriculture Organisation of

Ethics: The bridge we have created is ethical in the sense that it has a dependable purpose relative to its location, and its uses. By implementing a floating bridge, in a non-linear terrain in the city of Champong Chnnang it allows for effective, and efficient commute between two villages. This idea allows for the saving of time and money, by not implementing a less efficient method of transportation and trade between the two villages. THIS ISN’T GOOD ENOUGH, LET EDWARD ADD SHIT TO THIS TOO.

bio-plastics and is a potential contender in replacing some plastics synthesized by petroleum because of their biodegradable nature and physical properties. PHAs are somewhat similar to the well-known synthetic polymers that are low density polypropylene and polyethylene; furthermore the disposal of PHAs as bio-waste made them more attractive in the hunt of sustainable development of bio-plastic. These PHAs contained a class of polyesters naturally present which has been accumulated by many microorganisms

Introduction: In our everyday life, plastic has become king. It has been omnipresent for so long, we no longer notice its presence in our lives. Plastics are present in everything, from packaging to electronics to toys to tools…etc. This raises the question of when it was that plastic was first integrated into our lives. To discuss this, we must turn to the first kind of plastic that was man-made: Parkesine. In 1862, a British inventor by the name of Alexander Parkes introduced the first man-made

world consistently demonstrated that plastic materials make up 60-80% of marine debris. That little dolphin or penguin who accidently ingests that one plastic bag will die a slow death because they didn’t know better. One of the sites that have a density of 700 plastic debris is the North Sea in Europe. Currently, only Ireland has banned plastic bags and the United Kingdom put a 5-pound tax on plastic bags. All the other states surrounding has done anything about it yet. This is not okay because plastic

1. This project is set up in Sri Lanka which is an island nation and in the Indian Ocean located in the southern part of the Indian subcontinent. The project mainly focuses on Colombo where the commercial capital of Sri Lanka is. According to the “Global Challenges in Engineering” (Baillie & Armstrong, 2016), the population of Colombo was 5.36 million in 2002. Benefit from the open market policy published by new government, the economic condition was improved significantly. The population of Colombo

changed. For example instead of using a polyethylene cup and head, modern engineers prefer ceramic as it has significantly higher joint, wear resistance. Also metal on metal is still used but not to the same extent because of research conducted that sees the metal corroding over time and poisoning the patient’s insides. The bone cement is now not used anymore giving the cap a rough texture which the bone can grow onto and attach more properly. Metal on polyethylene is the most common choice now as it

other smaller computers. LCDs are used to display arbitrary images or fixed images with low information content, which can be displayed or hidden. Twisted-nematic liquid-crystal display (TN-LCD) is a common type of LCD which consists of a substance called nematic liquid crystal that is confined between two plates of polarized glass. That process uses very little power consumption and low operating
