Goniophotometer were used to measure the paper roughness, whiteness gloss and color properties. The results show that printer type and paper properties have significant effect in reproducible color gamut. Result show that Konica Minolta CF3102 has significantly higher gamut volume especially in yellow region than two other printers (Konica Minolta bizhub C450 and the Konica Minolta bizhub C451). It was found that paper with high whiteness, low surface roughness, and high gloss exhibited a high gamut volume
larger tensile stresses. These effects resulted in poor surface finish. At higher Peak Current, the impact of discharge energy on the surface of workpiece becomes greater and thus resulting erosion leads to the increase in deterioration of surface roughness. The recast layer is the outer region of the heat affected zone and consists of superimposed strata derived from melted and resolidified workpiece material as seen in Figure 5.

Eight lines, that’s what I have, they sit above my left knee. They are a reminder of a mistake I made and one I will never make again. I self-harmed and it did not solve my problem at the time but it taught me a bigger lesson. It taught me that it does not fix your problems and it only hurts those around you and it shouldn't have been an option in the first place. My entire life I have always struggled with depression. I didn’t show any outward signs of it to the world around me until I reached third
Abstract The most important process parameter for the manufacturing done by CNC now a days is the surface roughness (SR) and material removal rate (MRR). To maintain good quality of products surface finish plays vital role and MRR helps to increase production. Surface roughness and material removal rate is one of the important quality control parameter for evaluating of production process. Efficient turned component improves many functional attribute like excellent tolerance, less
well as the overall size of the banana. The objective of the project is to find a relation between the surface roughness of banana peels and the ripening of the fruit. Previous studies have measured the surface roughness of apples and pumpkins , among others. The results from this study will be used, in conjunction with previous work, to find correlations between the surface roughness and other properties of the fruit. As a banana ripens, various chemical reactions are occurring between the peel
It was my first day in school. I was very nervous and shy as I entered my first class. I could see none of them were Asian or Indonesian. They were all Australian instead. Contrary to what I thought, they were all very friendly. They started to talk about my favorite sport, so I told them that I liked football and then asked them whether they played football or not. Later I was asked to play football with them, but I was startled to discover that my football was different from theirs. What I meant
response surface methodology (RSM) technique. Two mathematical models correlating process parameters with response parameters such as surface roughness and micro hardness were obtained. Influence on surface roughness can be explained as ahead; From results it is seen that increase of burnishing speed deteriorates the surface finish. Generally surface roughness increases with the feed and there is an interaction between ball force and the feed. Combination of low feed (0.07 mm/rev) with large force
business, from extra expense, to how to deal with the problem, and prevent it from happening in the future. Danger of Workplace Violence Upwards of two million American workers are casualties of work environment violence every year. Work environment roughness can strike anyplace, and nobody is resistant. A few specialists, nonetheless, are at expanded danger. Among them are laborers who trade cash with people in general; convey travelers, products, or administrations; or work alone or in little gatherings
the O-Train MUP and randomly administered the form to 19 individuals on March 30, 2014. Roughness Index As stated earlier, due to financial and weather condition constraints, the performance evaluator was unable to implement an objective method to assess the O-Train MUP’s performance. An example of an objective performance assessment that could be implemented in the future is testing the International Roughness Index (IRI). The IRI was created to statistically indicate surface irregularity in roads
the surface of oxygen modified PP which was observed by Fourier transform infrared spectroscope and it was resulted in the improvement of wettability. The surface morphology and roughness of the PP films before and after the oxygen plasma treatment was analyzed by Atomic Force Microscopy (AFM). It was found that the roughness of
John Constable’s The Hay Wain was produced in 1821 by way of oil on canvas during the Romantic period of the 19th century. This work being one of Constable’s most notable works. Various elements and thought processes implemented in the painting make it an accurate representation of the Picturesque Romanticism style common of this period. The article “Constable, John” found in The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide mentions that Constable was an English landscape painter
Though the phenomena itself is as old as any other branch of Physics, the focus on wear aspects of Material and development of the field as a separate study in its own right is rather new. Tribology is a relatively young branch of Mechanical Engineering, introduced in 1966 by Prof. H. Peter Jost in his report for the UK Department of Education and Science. The Oxford English dictionary defines Tribology as “the branch of science and technology concerned with interacting surfaces in relative motion
Silica sand is a sort of silicate mineral and largely compose of silicon dioxide (SiO2) (Liua et al., 2015). It is easily available in all parts of the world and is commonly used for the production of dams, ceramic matrix composites, bridges, construction of buildings, roads and bricks as well as in the production of refractory materials for high temperature furnaces. Some of the most important properties of silica sand are high chemical resistance, good insulation, high hardness, high temperature
West must have peculiarities of character created by the peculiar circumstances of the new world.” The three characteristics he mentioned were, specifically: A spirit of adventurous enterprise, independence of thought and action, and an apparent roughness (rudeness of manners). He felt that these traits were commonalities shared by the first explorers of the west, such as the fur trappers and others, including farmers, miners, and railroad workers (Hollitz,

I. Introduction Though there are many ways to elevate the symptoms that occur with arthritis of the knee, many do not restore the patient’s life to its normal state. This is why many patients chose to have a total knee replacement (TKR) surgery done. In the United States more than 400,000 primary knee and hip arthroplasties are performed each year, costing more the over $10 billion (bachmeier). Total knee replacement (TKR) is done to restore joint functionality and to relieve a patient from pain
Abstract Electric discharge machine developed in late 1940’s has been accepted worldwide as a standard process in manufacturing and is capable of machining geometrically complex or hard material components, that are precise and difficult-to-machine such as heat treated tool steels, composites, super alloys, ceramics, nitrated alloy, carbides, heat resistant steels etc. EDM has become an important and cost-effective method of machining extremely tough and brittle electrically conductive materials
(a>1025/°C) conventionally used in the optical industry. The technique involves active beam integration to obtain an intensity irradiation profile with a good uniformity over large spot sizes and is applied to preheated glass samples with initial rms roughness up to 500 nm. To find out the conditions for successful and reliable use of the proposed laser polishing method, the laser-driven heating process was monitored by means of the surface and depth temperature
Study of Oxidation of Stainless Steel in Hot rolling Background Studies on the oxidation of stainless in hot rolling have obtained much attention during the last few decades where the finishing temperature ranges from 850-1100 °C. Oxidation is the formation of oxide rich scale that slows down further oxidation when formed. In stainless steels at elevated temperatures (up to 1100°C), this oxide scale is necessary as it is predominantly chromium rich and prevents further oxidation. On the other hand
