Cutting boards come in all shapes, sizes, colors, and are comprised of various materials such as wood, bamboo, acrylic, plastic, glass, marble, and pyroceramic. There are various steps one can take to ensure proper cutting board sanitation and food safety.

I assist discarded collectives of objects to volunteer themselves for inclusion into the privileged legacy of flatness – assuring them they can be transformed into Painting. Reducing my interventions - often to mere arrangement - respects the possibility of this transformation while frankly retaining the objects' original functional identities. Every surface of any object is a readymade painting – especially flat ones. By stacking objects and aligning their surfaces on one privileged side into a flat mega-surface, I am composing and collaging – even building – a painting. With my amateur interest in German I latch upon the double meaning of "Bild" to title my objects, describing my continued interest in the space between painting and sculpture. All my projects transform found objects into ambiguous objects described by Donald Judd as "neither painting nor sculpture". In addition to the Bilds projects such as the Cutllages, the Kitsch Paintings, Soap Drawings, Text Tubes, and List Drawings investigate different ways to transform the found object into painting.While my work is formalist it is decidedly post-modernist in its embodiment of the qualities described by Craig Owens in The Allegorical Impulse: Toward a Theory of Postmodernism.

In which ways can the process of trimming dispersion coated board products be optimized so as to reduce material waste and increase production efficiency? This is the question that this master thesis report seeks to answer. In paper production, alot of waste is generated when cutting production reels into customer reels. Some material waste are necessary in order to ensure good quality, however a large amount of the wastecould be reduced if the cutting process was to be optimized. During this project, carried out at a forest company, a mathematical optimization model was developed in order to reduce waste and save costs. This model is based on a cutting stock problem using column generation approach. It provides as its output cutting patterns and an optimal allocation of rolls for production purposes, which implies minimizing the number production rolls needed.The visualization of the results could also be used to achieve optimal stock levels, and easier keep track on how to use the material available in stock. Findings show that there are potential savings to be done. Simulations suggest an implementation of this model could result in material savings of around 7 %. This could also translateto environmental savings in CO2, where every decrease of one tonne material equals to adecrease in CO2emissions of 500 kg

Environmental issues have become a priority in business strategies aimed at supplying markets that are increasingly demanding and interested in companies that seek to protect the environment. Cutting fluids are one of the main pollutants in the machining processes of the metalworking industry, thus requiring special care in their environmental management. Early researches aimed at improving cutting fluids and devising more effective application methods focused on enhancing technological and economic aspects. However, in recent years, the efforts of researchers and manufacturers have concentrated on the development of environmentally friendly cutting fluids and new technologies aimed at the reduction or even the elimination of cutting fluids in order to satisfy increasingly strict environmental, public health and work safety regulations, as well as to align machining processes to an integrated system of quality, occupational safety and environmental management. The objective of this work is to find examples and contribute toward the search for viable solutions to minimize the environmental impacts caused by the use and disposal of cutting fluids, correlating these solutions to good environmental practices and to the 3Rs principle. This work involved a comprehensive bibliographic review focusing on the identification of studies that show the environmental concern of the metalworking industry in the search for opportunities to adopt good environmental practices in the management of cutting fluids. It was found that, despite the development of less environmentally harmful cutting fluids and of methods for the application of increasingly small quantities, this basic product still requires environmentally-based management for its correct use. Therefore, there is a need for awareness-raising about the environmental impacts that can be caused by the incorrect use of cutting fluids... (Complete abstract click electronic access below)

The percentage of low-grade material composing the annual hardwood lumber production in the U.S. is on the rise. As a result, finding markets for low-grade and low-value lumber has been identified as a top priority by researchers and industry associations. Computer simulation has been used by the manufacturing industry for several decades as a decision support tool. Simulation programs are commonly used and relied on by researchers and the industry alike to conduct research on various aspects of the rough mill from processing to recovery efficiency. This research used the ROMI-RIP and ROMI-CROSS simulation programs to determine specific conditions that led to optimal part yield when processing No. 3A Common, 4/4-thickness, kiln-dried, red oak lumber in rip-first and crosscut-first operations. Results of the simulations indicated that cutting bills with narrow part widths and short part lengths are conducive to obtaining optimal part yield while processing No. 3A Common lumber. Furthermore, it was found that as the percent of No. 3A Common lumber in a grade mix increases, part yields and sawing efficiencies decrease. The results also indicated that higher part yields will be obtained when processing short-length No. 3A Common lumber between 6 and 8 feet in length.

Sammanfattning Bakgrund Fokus för studien är att uppmärksamma Socialstyrelsens vägledande information rörande könsstympning av flickor och kvinnor. Traditionen innebär total eller delvis borttagning av det kvinnliga yttre könsorganet, vilket innefattar avsiktliga skador som förändrar eller orsakar defekter på det kvinnliga könsorganet utan medicinska skäl eller grunder (WHO, 2008). Till följd av migration och befolkningsomflyttningar har traditionen kommit att uppmärksammas internationellt och även i Sverige. I Sverige har traditionen en tydlig relevans för socialt arbete eftersom könsstympning diskuteras och definieras som våld mot kvinnor/barn, förtryck, heder, brott mot mänskliga och barns rättigheter (Talle, 2008). Myndigheter i Sverige står inför en utmaning att informera, uppmärksamma, integrera och arbeta preventivt med denna målgrupp.   Syfte Syftet med studien är att beskriva och analysera hur socialstyrelsen via sin webbplattform förmedlar kunskap om könsstympning av flickor och kvinnor. Utifrån hemsidans tillgängliga texter granskas och analyseras vägledning och kunskapsstöd riktade till olika professioner, exempelvis socialtjänsten och hälso-och sjukvård. Vidare studeras hur kunskapsstöd vägleder professioner till att förstå och handla i frågor som rör könsstympning som ett arbete på samhälls-, grupp och individnivå. Utifrån det analyseras hur socialstyrelsen främja det sociala arbetet kring könsstympning.   Metod Studien bygger på en kvalitativ forskning baserad på systematisk litteraturstudie och induktiv ansats. Litteraturstudien grundades på analys och granskning av socialstyrelsen kunskapsstöd. Genom en webbaserad innehållsanalys granskades 53 publicerade dokument som direkt eller indirekt berör könsstympning av flickor och kvinnor.     Resultat I resultatdelen identifieras tilltänkta mottagare av det publicerade materialet som illustreras i form av ett diagram. Den allmängiltiga informationen representerar hälften av urvalet. De två mer framträdande grupper identifieras som Hälso-och sjukvård och den berörda målgruppen. I mindre omfattning riktas material till socialtjänst och samhälls-/hälsokommunikatörer. Resultat påvisar att Hälso-sjukvården i sitt arbete med könsstympning, har i större omfattning tillgång till praktiskt och teoretisk vägledning i jämförelse med de andra representerade mottagargrupperna.   Slutsatser Studien visar att socialstyrelsen förmedlar ett arbete mot traditionen på individ-, grupp- och samhällsnivå. Information kring könsstympning av flickor och kvinnor stämmer i stort sett överens med tidigare forskning gällande ursprung, förekomst, utformning och konsekvenser. Studien visar att Socialstyrelsen är en källa för kunskap och information kring ämnet. Det föreligger dock skillnader i den praktiska vägledningen som skapar grund för handling. Vid det konkreta arbetet på individnivå framträder skillnader beroende på om frågan aktualiseras inom hälso- och sjukvård eller socialtjänst.
Abstract Background The focus of the study is to draw attention to the National Board of Health and Welfare directory information concerning female genital mutilation (FMG). The tradition involving the total or partial removal of the female external genitalia, including intentional damage which alter or cause defects on the female genitalia without medical reasons or reasons (WHO, 2008). As a result of migration and population movements, the tradition came to be recognized internationally and in Sweden. In Sweden, the tradition has a clear relevance to social work because FGM is discussed and defined as violence against women/children, oppression, honour, violation of human and children's rights (Talle, 2008). Authorities in Sweden is facing a challenge to inform, alert, integrate and work preventively with this audience. Purpose The purpose of this study is to describe and analyse how the National Board of Health and Welfare by its web platform conveys knowledge of FGM. Based on the websites available texts examined and analysed guidance and knowledge subsidies to various professions, such as social and health care. Further studies show knowledge and support guides professionals to understand and act on issues related to FGM as a work of social, group and at a individual level. Based on the analysis of how the National Board of Health and Welfare promotes the social work of FGM. Method The study is based on a qualitative research based on a systematic literature review and inductive approach. The literature review was based on analysis and review by the National Board of Health and Welfare knowledge support. Through a web-based content analysis examined 53 published documents that directly or indirectly affects FGM. Results In the results section identified the receiver to think of the published material illustrated in the form of a diagram. The universal information represents half of the sample. The two prominent groups identified as Health and the touch target. In smaller scale material is directed to social and community -/health communicators. Results demonstrate that the health-care system in his work on FGM, has been more widely access to practical and theoretical guidance in comparison to the other receiver groups represented. Conclusions The study shows that the National Board of Health and Welfare conveys a work against the tradition of individual, group and societal level. Information about FGM are broadly in line with previous research on the origin, presence, design and impact. The study shows that the National Board of Health and Welfare is a source of knowledge and information on the subject. However, there are differences in the practical guide to creating a basis for action. In the concrete work at the individual level, disparities, depending on whether the issue arises in healthcare or social services.

The Breakaway of Rigid-flex board is hard to take apart by hand and not easy to get a regular edge on either. Therefore, we use a laser beam to manufacture a V-shape cut for a certain depth of groove before bend the board and then the stress concentration will be generated at the part. In this way have a regular edge can be fabricated easier. At first, we have to get the depth of the cutting on the board by a practical test to get a graph. And then, the curve of the graph will be used for the rest of the Rigid-flex board while making the V-shape cut to get a desirable parameter. By the way it is not only saving time and material, but also reducing the costs of testing. The thickness of Breakaway is 5.67mil,by testing the parameter is PLS WID.: 10 ms /Pulse: 2 shot /Mask: 1.8 /Energy: 1.22 mj

In past decades, the kitchen tools design towards to exquisite and variety. However, due to shortened product life, diversity customer demand and other reasons, most of manufactures are often too shorten the developing cycle, cause ignoring the real demands of consumer, which led to the product are unable to meet user expectations. In this study, Quality Function Deployment (QFD) has been used as a research methodology for cutting board product development. The method has been use for identifying the customer demands and needs, converting to related technical specifications and engineering factors. The cutting board product, which defined by customer demands and needs, has been deployed by QFD methodology in this research. The importance of quality, quality strategy setting and technical target value has been calculated by QFD method after collecting the market information and organizing the voice of customer. Comparing the target product and controlling experiment, users are more satisfied in terms of quality requirements of the product as following four items, “easy clean”, “light weight”, “easy to handle” and “ingredients is not easy falling”. In quality control items, “material”, “surface”, “size”, “design” and “ergonomics of the handle” indicating more important to user. The calculating result indicates following quality control items, “material”, “design”, “color”, “size”, “surface”, “pattern”, “hardness”, “hang hole”, “anti-skid pad”, “ergonomics of the handle”, “anti-skid grain” and the “well around perimeter”, should be set as technical control items in design rule for product developing.

In recent years, the products of flexible electronics, smart phone and tablet PC are popularly used by consumers. And the functionality and demand has been growing quickly since 2010. It is indispensable, for these consumer electronics, to apply FPC(Flexible Printed Circuit). Therefore, not only is the utilization rate growing year by year but the technical level is also improved. Due to the breakthrough of the production bottleneck for the slim structure with ultra-fine line, the packaging of electronic components strengthens the structural density and precision. In this thesis, the FPC adhesion relation to its cover layer was mainly studied by analyzing the structure and property of cover layer and solutions for the difficulties in the current cover layer process were provided. We used UV-YAG laser cutting machine to conduct the cutting experiments of cover layer in order to obtain the optimized cutting parameters and prevent a poor adhesion which causes permeation in the subsequent gold-platting process and abnormal appearance. In this thesis, we studied the liquidity of the three types of cover layer adhesives after heated and quality improvement measures for the soft adhesive process. The optimized laser cutting parameters were found and a good cutting quality was obtained according to the result from several cutting tests by adjusting four parameters of laser cutting machine (laser power, laser frequency, cutting speed and cutting times). Moreover, the yield and capacity of FPC was improved without quality impact. The final study was the characteristic of the laser power decrease with the process time and the power decay due to the dust impact on the laser path. It’s proofed that the laser power decay can be improved and the capacity can be stabilized by enhancing the effect of dust removal with a designed structure of dust removal cover. Hopefully, this thesis is helpful to the practical application of laser cutting in the future.

Knowledge economy is the major economic growth sectors in the economic development in recent years, and how to manage knowledge becomes a major research topic. The past studies show that selection, education, assignment and retaining for knowledge workers is the key success factors of knowledge management. Many companies and countries consider attracting the best talent of the world is the most important goal to develop the competitiveness but training knowledge workers needs to spend a lot of resources .However, there exists the risk that well- trained knowledge workers may leave and serve another company after training. This risk is particularly harmful to small companies. To resolve this problem, this research attempts to break down the knowledge-based work into different workstations and individual officers by the concept of standardization of production processes. So, the knowledge which is used to complete the work at each station contained less than the original, and companies can reduce training resources in each station workers. This study tried to find out the knowledge transfer way by literature research. The past research results showed that using knowledge externalization we can transfer knowledge by documentation. Knowledge-based work can be cut into sub-station operations by the output session file and documents. This research also studied the circuit board maintenance industry as a case study, and the result showed that knowledge-based work can be successfully cut into the work processes of individual workstations and the knowledge of the various stations and training needs were a lot lower than the original. It solves the personnel training problem and should be able to help small companies to solve the shortage of knowledge workers.
