Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

Ridhästens samling : en jämförelse av subjektiva bedömningar och objektiv kinematisk analys

The modern veterinarian in horse practice is often consulted by horse owners concerning riding problems. These problems are more complex and show other characteristics than traditional lameness. For the diagnostic process and to give adequate advice the veterinarians need an understanding of riding terminology and problems related to riding. It is also of high importance that riders, trainers and veterinarians increase the knowledge of equine biomechanics and how these are influenced by the rider. Collection is an important concept in the riding terminology.

Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

Processer och metoder som möjliggör för en effektiv produktframtagning

The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they?re facing and offers a great potential to create significant competitive advantages.

Kapslingen skulle uppfylla de krav som finns uppställda för klassningen IPX7.Nexus Marines navigationssystem och nuvarande sortiment studerades för att ge en bild av vilka funktioner som kapslingen skulle innefatta och i vilken miljö den skulle användas.

Risks Related to the Maritime Transportation of Oil and Gas (mainly Crude oil, LPG, and LNG) -A Conceptual Study and Empirical Outlook on the Baltic Sea and UK Territorial Waters to Mitigate Risks

Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.

Kan ett ökat intag av omega-3- fettsyror påverka testosteronnivåer hos kvinnor med PCOS?

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.

Green feed in the marine fish farming : how to communicate water benchmarks to stakeholders

Global catch fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.

The vertical farm : varför har idén uppkommit och hur är den tänkt att fungera?

By immersion in the situation of the food production today and a historical study of how past development has led us to this point, one goal of this essay is to discuss whether the current way of farming can be applied in a sustainable future. Another objective of the essay is to study the vision Vertical farming as an alternative approach, and to focus on different aspects of this phenomenon in order to provide as comprehensive a picture as possible.The paper, thus, seeks to broaden the views for alternative approaches regarding a well-established method which we often take for granted. The aim is also to initiate a discussion around the need to also take radical ideas in regard if we want to face the future in a sustainable manner. The method is a qualitative literary study where scientific articles and papers have been used to discuss the issues: why has the idea of Vertical farming arisen, what is Vertical farming and how is the Vertical Farm meant to operate? Does Vertical farming have a place in the sustainable city of the future? For a long time us humans lived as one with nature, in a symbiotic relationship in which we gave and took as a functioning part of an ecosystem.

Cabotage

I studien ställs frågan hur den historiska förordningen ?produktplakatet? från 1700-talet ska tolkas i ett modernt juridiskt perspektiv. Produktplakatet reglerar än idag ett förbud för utländska redare att bedriva sjöfart på svenska vatten. En sådan aktivitet kallas för cabotage, vilket är franska och betyder ?kustfart?.Produktplakatets lydelse och den praktiska tillämpningen av förordningen genom behörig myndighet skiljer sig åt på olika sätt.

En internationell jämförelse av miljölagstiftning avseende växtnäringsläckage med ursprung i jordbruket

SAMMANFATTNINGÖvergödning har de senaste åren blivit en stor och omdebatterad fråga i många EU- länder.Även om problemen har minskat en del är detta inte tillräckligt, vi ser fortfarande fiskdöd,syrefria bottnar och giftiga algblomningar. Hur långt ska vi gå för att kunna övervinnaövergödningsproblemen? Genom olika sorters lagstiftning, ekonomiska styrmedel ochrådgivning har vi nått en bit på vägen, men fortfarande krävs det mycket arbete innan vi haruppnått målet. Jordbruket har pekats ut som en av de största källorna till övergödning pågrund av överskottet av kväve och fosfor som varje år urlakas ur våra jordbruksmarker.Inom EU finns sedan 1991 en gemensam lagstiftning; Nitratdirektivet. Syftet med direktivetär att minska nitratföroreningar och andra föroreningar från jordbruket, då dessa påverkarsåväl yt- och grundvatten som kust- och havsvatten.

Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.
