Answers - Essay Example Hot rolling is a metal processing process that occurs above the material’s recrystallization temperature. It uses large pieces of metals in the process, such as slabs. On the other hand, cold rolling entails metal processing below the material’s recrystallization temperatures. It involves passing small pieces of metals through rollers. Hardwood has straighter and cleaner grain patterns. They possess higher density and are more fire resistant compared to softwoods. Hardwood is more applicable for engineering works, making of floors and high-quality furniture. They also have slower growth rates. Softwoods have a lower density and relatively cheap to in terms of cost. Softwoods have reduced fire resistance capacity. The woods also possess rugged grain patterns. Soft woods use is limited to low-quality furniture and is not preferred for engineering works (Bawa, 2009). By definition, OSB is a material of high mechanical properties, such that it becomes particularly suitable for use in heavy load-bearing applications especially in construction works and industries. On the other hand, MDF is a wood product that is engineered by breaking down softwood or hardwood residuals to make wood fibers. The process often takes place in a defibrator, where it gets combined with resin and binder. The product has a higher density than plywood. Stress is pressure or tension exerted on a material object. Strain is a force that tends to pull or stretch an object to an extreme degree, usually, damaging levels. By definition, elastic modulus is the ratio of force exerted on an object to the resultant deformation it undergoes. Plastic deformation is a process whereby force is exerted to a metal or plastic object to change its shape permanently. For the yield strength, it is a stress point where it is possible to produce a given particular plastic deformation amount. Toughness is the actual ability of any material to absorb energy without fracturing

Porter's five forces - Case Study Example Start up of soft drink industry requires high financial capital, labor, marketing, warehousing and advertising. The situation makes it difficult for a competitor to enter into the industry and expand. Additionally, Coca Cola Company has made huge investments in their advertisements which resulted to brand loyalty with its customers throughout the world. For example, Coca Cola Company’s advertising strategy made it attain a larger market share in 2011 than its rival Pepsi. The market of Coca Cola was at 41.9%, the market share for its rival Pepsi was at 29.9%. The advantage was driven by huge investment Coca Cola Company makes in advertising (Russell). The main substitutes of Coca Cola products are bottled water, tea, coffee and sport drinks. Consumers are currently more concern about their health. They have begun cutting down on the demand of sodas because of the view that they contribute highly to obesity due to its high caloric content. Additionally, tea and coffee are a threat to Coca Cola products because they have caffeine and customers can decide to buy it. This makes the substitute products stronger and a threat to the Coca Cola Company (Russell). Raw materials essential for manufacturing Coca Cola products are basic raw materials such as sugar, flavor, color and packaging materials. The suppliers of the above materials have low bargaining power because materials are easy to obtain and there are many suppliers in the market. However, with recent inflation of the price of goods, cost of materials such as sugar and packaging increased. This affects the profits of Coca Cola Company (Hill and Jones 44). The Coca Cola Company and any other company distribute their soft drinks to convenience stores, restaurants, supermarkets and large grocers for resale directly to customers. They are the buyers of Coca Cola products, and they buy the products in large quantities for

Improving Business to Business Marketing in TCL Business Research Paper

Improving Business to Business Marketing in TCL Business - Research Paper Example Over the past two years, most small and medium businesses have been badly impacted by the recent economic downturn with TCL not having been spared from the impact. During this period most businesses are cutting costs in order to remain competitive in the business, this grossly affects TCL’s business as its revenue stream is mostly reliant on the marketing budgets that companies set. Over the past year, with reduced business, TCL recorded a drop in revenue by 25%, and the business is increasingly finding it hard to get new business and establish new clients. It is imperative that TCL make a change to its current business to business marketing. In view of this, this business report analyses and addresses various aspects of a business to business marketing that TCL needs to address in order to be able to efficiently meet its objectives. In doing so, the report will focus on how TCL can restructure its marketing mix, how the business networks and relationships impact TCL’s business, how it can rearrange its sales team for effective impact at low cost. With the recession, most of TCL customers are cutting back on their marketing spending. As can be noted from TCL’s product portfolio, TCL gives precedence to offline business marketing using tools such as radio and television for their clients. The very nature of such advertising means being expensive implies that TCL is losing a lot of money in this area. Since TCL also offers other marketing services such as online marketing, it is important for the company to explore its product portfolio and see how it can restructure it well enough for the business that is focused on cost-cutting. Trends in the recession show that more companies which are cutting costs are tending towards online marketing not only because it is cheaper, but because of the reasoning that most end consumers being thrifty during these periods also tend to go online in search of better and cheaper deals (Chlebisova, et al, 2011:1 234-1236). Indeed Court (2009:71) note that key advertising tools that most companies use for advertising and marketing during the recession are the use of the internet, mobile devices and the social networking which are far cheaper and much more effective in a recession-stricken economy. Most companies prefer to use a combination of these with traditional media (Bulearca, & Bulearca, 2010).

Effect of Positive and Negitive Thinking Essay When life gives you lemons, make grape juice, and leave the world wondering how you did it. The effects of both positive and negative thinking affects the world in the same sense, to have been given the different options to see the world and deciding which path to take. With each decision and action is the same as Newton’s law of gravity what goes up must come down, it’s a natural accordance that will continue on in the never ending circle of life.

Throughout life someone somewhere has heard, be it through friends or family, things such as If you think bad thoughts, then youll jinx it or If you think the worst, the worst will happen. Sadly now the world is slowly becoming consumed by more negativity then ever before, making these more then just little wives’ tales and they all start in the mind. When people are negative, either to ones’ self or others, it expands and jumps out. Think of a school environment, on a day-to-day basis, all those people are moving together, all those different personalities are clicking or crashing with one another, and all range of emotions are swirling around, one individual in the group could be having a bad day for a number of reasons, they might unintentionally do or say something that could in turn ruin another individual’s day.

Impacts on Morphology of Porous Polymethacrylate Adsorbent

Impacts on Morphology of Porous Polymethacrylate Adsorbent Study of the effect of external heating and internal temperature build-up during polymerization on the morphology of porous polymethacrylate adsorbent Chan Yi Wei, Clarence M. Ongkudon, Tamar Kansil Abstract. Modern day synthesis protocols of methacrylate monolithic polymer adsorbent are based on existing polymerization schemes without an in-depth understanding of the dynamics of pore structure and formation. This has resulted in ineffectiveness of polymer adsorbent thereby affecting final product recovery and purity, retention time, productivity and process economics. The problems magnified in monolith scaling-up where internal heat buildup resulting from external heating and high exothermic polymerization reaction was reflected in cracking of the adsorbent. We believe that through careful and precise control of the polymerization kinetics and parameters, it is possible to prepare macroporous methacrylate monolithic adsorbents with controlled pore structures despite being carried out in an unstirred mould. This research involved the study of the effect of scaling-up on pore morphology of monolith, in other words, porous polymethacrylate adsorbents that were prepared via bulk fr ee radical polymerization process by imaging the porous morphology of polymethacrylate with scanning electron microscope. INTRODUCTION Monolithic supports are novel developing technology with high potential, more so than conventional particulate supports. A lot of researches and developments have been conducted in the past decade to utilize monolithic supports as the stationary phase in chromatographic separation due to its scalable feasibilities and better hydrodynamics. The reason lies within the presence of interconnected macro pores in monolithic sorbents that allow convective transport mechanism instead of diffusion that features as the only mean of transport mechanism for particulate support. The monolith hydrodynamic property is predominated by convective transport mechanism, an important feature of a chromatography of larger molecules that are unable to penetrate into the internal structure of particulate support [1]. Monolithic support also features lower pressure drop that varies with different pore structure orientations [2, 3]. Such feature allows for higher mobile phase flow rates to be applied which co uld enhance the separation efficiency. Despite the low absolute surface area, the increase in flow rate actually more than makes up for the lost capacity for larger molecules due to smaller specific surface area. The comparison of physical characteristics between monolithic supports and particulate supports extend much further than pore size alone [4]. Monolith is constructed in an unstirred mould that features significant lack of interfacial tension between an aqueous and an organic phase thus leading to large interconnected flow-through channels. In contrast, bead polymers prepared from identical polymerization mixtures but in a suspension polymerization process do not exhibit the same type of macroporous structure with large flow-through channels [5]. Unstirred mould also results in poorer heat transfer, thus leading to formation of temperature gradient across the monolith sorbent with nuclei forming at different rates and porous channel forming at different sizes [6]. This inherent issue magnifies during monolith scaling-up with obvious cracks observed during polymerization process. The key to achieving controlled macroporous structure is dependent on gaining control over the process kinetics within the unstirred mould (e.g. temperature of reaction) [7]. This work involved the use of scanning electron microscope to visualize the morphology of porous methacrylate monolithic polymer under different porogen concentrations (50%, 60% and 70%) and different scales (2ml and 150ml) which provided a better insight on the effect of scaling-up on pore morphology. MATERIALS AND METHOD The monolith was prepared via free radical co-polymerization of cross-linker EDMA and GMA as functional monomers. EDMA/GMA mixture was combined with an alcohol-based porogen solvent in the proportion of 35/15/50(GMA/EDMA/cyclohexanol) making a solution with a total volume of 160ml. AIBN (1% weight with respect to monomer) was added to initiate the polymerization reaction. The polymer mixture was sonicated for 20 minutes. The mixture of 2ml and 150ml were gently transferred into conical 0.8 cm Ãâ€" 4 cm polypropylene column (BIORAD) and 5.0 cm x 10 cm Econo column (BIORAD) respectively sealed at the bottom end. The top end was sealed with a parafilm sheet and placed in a water bath for 3 h at 60oC. Same method was repeated for 21/9/70 and 28/12/60 (GMA/EDMA/cyclohexanol) mixture. For conical 0.8 cm x 4 cm polypropylene column, the polymer resin was washed with 400ml methanol at room temperature to remove all porogens and other soluble matters. The polymer was then washed with 200ml d eionized water at room temperature to remove trapped air bubbles. Slightly different washing method for econo 5.0 cm x 10 cm, the polymer resin was extracted and placed in 1.0 L beaker filled with 600ml of methanol followed by placing it inside incubator shaker overnight under 140 rpm and 37oC. The next day, methanol was replaced with 600ml of deionised water under same incubation condition for 4 hours. For analysis of monolith morphology, the monolith was oven dried at 70à ¢- ¦C overnight and scanning electron microscopy was done at 15 kV using high resolution scanning electron microscope (Hitachi S-3400N, Japan) according to the manufacturer’s instructions. RESULTS AND DISCUSSION As can be observed from Fig. 1, both small scale and large scale porous polymethacrylate sorbents featured the increment of globules and pores size as the concentration of porogen was increased while monomer and cross-linked agent decreased. This phenomenon was due to the fact that an increase in the EDMA concentration led to the formation of more cross-linked nuclei and magnified by the presence of more functional monomer GMA consequently limiting their swelling which resulted in the concentration of the monomers in the swollen gel nuclei becoming lower than that in the solution. Hence, the chances of newly formed nuclei adsorbed by the macro pre-formed globules by coalescence of nuclei in abundance decreased greatly. The decline in local concentration of monomer decreased the size of the globules and thus contributing to the overall decrease in the pore size. External heating and exothermic heat buildup associated with the construction of polymethacrylate sorbent also play a role in the pore formation. The rate of initiator decomposition and free radicals formation rely heavily on temperature. The rate of radicals formation declines significantly at lower temperature than at higher temperature which results in lesser number of nuclei formed per unit time. This allows the coalescence of many nuclei that result in formation of larger preglobules and larger pore size as well as delayed formation of monolith. The same is true for pore formation at higher temperature. High level of exothermic free radical copolymerization reaction and external heating contribute greatly to immense heat buildup within the polymerization mixture. Reaction that takes place in an unstirred mould could contribute to exothermic heat buildup to a certain degree. Hence, the relative differences in the rate of radicals formation, nuclei and pore sizes can be deduced by observing the results in Fig. 2. The effect of heat buildup was profoundly increased in 150ml volume, in which cracking occurred and the monolith was considered unreliable. It was presumed that the exothermic heat build-up led to pressure build-up which eventually forced the monolith structure to break apart. FIGURE 1. Effect of both cross-linking agent and monomer concentration in the polymerization mixture on the surface morphology of methacrylate monolith. Polymerizations were carried out with a constant monomer ratio (EDMA/GMA) of 30/70; porogen concentrations of 50%, 60% and 70%; polymerization temperature of 60 à ¢- ¦C; AIBN concentration of 1% (w/w) of monomers. The SEM pictures show increased pores size with increased concentration of porogen in the polymerized feedstock. Microscopic analysis was performed at 15 kV. FIGURE 2. The effect of exothermic heat associated with the construction of large scale (150ml) polymethacrylate monolithic column on the surface morphology of methacrylate monolith. Polymerizations were carried out with a constant monomer ratio (EDMA/GMA) of 30/70; porogen concentrations of 70%; polymerization temperature of 60 à ¢- ¦C; AIBN concentration of 1% (w/w) of monomers. The SEM pictures show heterogenous globules and pores size distribution due to instant heat buildup generated from external heating and high exothermic reaction associated with the construction of polymethacrylate monolith. Microscopic analysis was performed at 15 kV. CONCLUSION There were not many differences when we compared the polymethacrylate adsorbents of both small scale and large scale monolith from 50%, 60% and 70% porogen content in terms of globules and pore sizes (Fig. 1). However, the effect of exothermic heat buildup was evident (data not shown) in large-scale monolith and without a doubt contributed to heterogeneous pore size distribution across the adsorbent compared to small scale monolith as evident from Fig. 2. Thus, further analysis is required in characterizing the pore size from different sections of the adsorbent in order to obtain a conclusive summary of the effect of scaling-up on the pore size distribution. ACKNOWLEDGMENTS We would like to thank UMS (University Malaysia Sabah) Research Priority Grant for funding this project that is essential in establishing the foundation for next step forward on the scaling up of monolithic adsorbent.

Cloning :: essays research papers fc

Cloning is a big issue now. Many arguments are going on about cloning humans being immoral. But what is cloning? Cloning is one or more offspring from a single ancestor; the genetic composition from the ancestor is identical to the offspring. No sex is involved in the production of clones, and since sex is the normal means by which new genetic material is introduced during procreation, clones have no choice having the same genes as their only parent. A clone of cells refers to the descendants of a single parent cell. Tumours are actually clones too. They are derived from one cell that no longer obeys the normal rules of growth control. Corals are another example of clones. Identical twins are even clones that are produced by splitting of a single embryo. So to keep it simple, members of a clone are genetically identical. Here is a diagram of how cloning is scientifically done.   Ã‚  Ã‚  Ã‚  Ã‚  The benefits of cloning might include, building a mass army of look-alikes or recreating Einstein or Elvis. You could clone livestock for steady supplies of food. There is no guarantee that the first cloned human will be normal. The fetus might get some disorder or disability that can’t be detectable by ultrasound. They might be born disabled. Disorders may show up later in their life. Such problems have been seen in other cloned mammals, such as reproductive problems. There is no reason to that this won’t happen in a humans’ case. Large scale cloning could eliminate genetic originality. It is diversity that causes evolution and adaptation. It prevents an entire species from disappearing because of a disease. The people out there who are childless because of a rare hereditary disease would be able to produce offspring that were genetically theirs. However, if the cloned sheep â€Å"Dolly† were anything to go by then less than one in a hundred success rate would cause many problems. More importantly, it is quite possible that cloned individuals will turn out to be at risk. We do not yet know the long-term effects of making an old adult cell nucleus to begin a new life again in an egg. Cloning :: essays research papers fc Cloning is a big issue now.

The Host Book Review

The Host Book Review Melanie Stryder is one of few â€Å"wild† human rebels who have evaded the alien souls currently taking over the Earth. With her younger brother, Jamie, and the man she loves, Jared Howe, Mel is on the run from souls who hunt down host bodies for use. Souls are creatures that rely on host bodies to survive. After insertion, they erase any mental presence of the being originally there and establish a claim over the body and mind. Earth is Wanderer's ninth planet, and Mel is her ninth host body.Upon waking inside her new body, she is shocked not only by the vividness of human emotions, memories, and senses, but quickly learns that Melanie Stryder is not willing to give up the entirety of her mind. Stephenie Meyer’s Twilight Saga has often been described as vampire fiction for people who don’t like vampires. It is fair to say that with The Host, her latest novel, she has once again managed to break the usual genre stereotypes. This time, writing a science fiction novel for people who don’t like science fiction.Unlike the most popular alien invasion movies and science fiction television shows, The Host doesn’t have Will Smith or Richard Dean Anderson to save the planet against a background of gun fire, secret weapons, and loud explosions. In The Host humanity is lost, vastly outnumbered and overwhelmed by superior technology. There are tiny pockets of resistance left; just a handful of humans who have yet been captured, but they don’t spend their days plotting to retake the planet from the aliens.Just trying to survive consumes all their time. The Host isn’t really about saving the planet from alien invaders; it’s a story about what it is to be human, about identity and about individuality. Most of all The Host is a story about the nature of love. Romantic  love, love of family, love of friends – all of these emotions are explored by Wanderer as she first surrenders to Melanieâ₠¬â„¢s emotional memories then surrenders to the emotions for herself.There is more than just memories left of Melanie though; she is trapped inside her own head unable to take control of her own body, forced to be an unwilling host to the alien Wanderer. Which makes things very interesting when Wanderer and Melanie eventually meet up with Melanie’s loved ones. Possibly the largest similarity between The Host and Stephenie Meyers Twilight Saga is the character of Wanderer. She has something of a Bella vibe going on. It is the way that they are both self sacrificing.Wanderer’s alien nature actually makes her even more self sacrificing than Bella which means that she needs others to look out for her and take care of her since she has little instinct for self preservation. Unlike the Twilight Saga, I would recommend The Host for both teens and adults. Stephenie Meyer wrote this book to attract a wide audience. All in all The Host makes a very compelling read. Avoiding the obvious science fiction cliches, it concentrates on humanity and the human emotions experienced by an alien invader who really wants to be a human.
