era as polymers era consider to its usage in our daily life and it is importance. A polymer has so many properties which are make it suitable to use it in our daily life. But the most common types which is can be daily usage polytetrafluoroethylene, polyethylene terephthalate, Polycarbonate and Polystyrene …..? 1. many of the products in cooking industry are made up from polymers such as cookware, cookware is one of the most important things in our daily and it is made up from type of polymer which
The human eye can be classified into two segments: anterior and posterior segments. The cornea, conjunctiva, iris, ciliary body, aqueous humor and lens are includes in the anterior segment and sclera, choroid, retina, vitreous humor are includes in the posterior segment. The outermost transparent membrane of the eye is cornea such are the corneal epithelium, bowman's membrane, stroma, descemet's membrane, and endothelium. The anterior segment is a fluid of the eye which contains the source of nutrition
Determination of Solid Surface Tension Using Contact Angle Method de Guzman, J.R., Labarez, K. H., and Yap, J.O. Department of Mining, Metallurgical, and Materials Engineering College of Engineering University of the Philippines Diliman Quezon City 1101, Metro Manila, Philippines jrannydeguzman@gmail.com Abstract—The objective of this experiment is to determine the solid surface tension of 20:30 ethanol-water, 0.5M NaCl, and distilled water using contact angle method on different solid flat
losses of meat products are largely influenced by the short shelf-life which they possess. In fact, the European Commission (2010) reported that retail food waste contributes to 58% of the total food wastage within the EU, thereby signifying the importance of extending the shelf-life of many products, including muscle-based products. Lamb meat is a very perishable food product with a shelf-life of nine to ten days under MAP or VP (Williams, 1991) making it hard for commercialisation and exporting
would be achieved using the commercial finite element program ABAQUS/CAE version 6.14. DESIGN TASK A method for preparing and testing a sample of the material comprises of the following steps: 1.Select material type to be used. (metals, polymers, ceramics or in combination) 2.Preparing a powder specimen of the material. (size of 15µm or thereabout) 3.Selection of an appropriate substrate. 4.Sample is fed into 3D equipment and ejected unto substrate via a high velocity inert gas. 5.Physical
1. INTRODUCTION Monocultures is a widely used agricultural practice that consist in producing or growing genetically similar, or essentially identical plants, over large areas, year after year. It has been shown that monocultures produce high yields as the plants growth without the pressure of other species and with uniform plant structure. However, monocultures are selected for specific conditions and when this conditions change there is a high risk of losing the entire crop. For that reason,
Introduction The sources of energy in the world majorly classified in to two types: renewable energy sources and non-renewable energy sources. , Solar energy, biomass energy, wind energy, tidal energy, hydro energy, and geothermal energy falls under renewable sources which are generated directly from the nature like the sun, rain, wind, tides, and it is possible to generate it over and over whenever it is needed and they are non-exhaustive.1 Whereas, non-renewable energy sources include natural
Introduction. Urban population growth and increase in industrial enterprises, as well as the change in business life has led to a sharp increase in the proportion of waste that forms as a result of household activities. A significant proportion of them are solid wastes. The accumulation of the municipal solid waste and their disposal is a global environmental issue of our time. The waste poses a serious threat to the natural environment as a source of mechanical, chemical and biological contaminants
Introduction What is DNA? The scientific definition is “deoxyribonucleic acid, the biological polymer that stores the genetic information in all free-living organisms. Now that the definition has been stated, let’s now define what DNA means to a crime scene or case investigator. This paper will explore deoxyribonucleic acid, also famously known as (DNA). How it is collected and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect
in very low shear rate regions and very high. Since is generally less than one,goes to infinity at a very low shear rate (see Figure 3-5) rather than to a constant, , as is often observed experimentally.Viscosity for many suspensions and dilute polymer solutions becomes constant at a very high shear rate. This cannot be solved via the power-law model (Kim, 2002). Figure 3-5 Flow curves of power-law fluids,(a) shear-thinning fluid ( n < 1). (b) Newtonian fluid ( n = 1),(c) shear-thickening
