Wicking ? Utvärdering av två standarder
Syftet med rapporten är att utvärdera och jämföra två standarder, AATCC Test method 198-2011: Horizontal Wicking of Textiles och AATCC Test method 197-2011: Vertical Wicking of Textiles. Standarderna publicerades år 2011 av American Association of Textile Chemists and Colorists. Standarderna mäter wicking, det vill säga, med vilken hastighet som vätska transporteras genom textil, med en horisontell och en vertikal testmetod. Hastigheten anges i olika enheter beroende på standard, enheten för AATCC Test method 197-2011: Vertical Wicking of Textiles är mm/s och AATCC Test method 198-2011: Horizontal Wicking of Textiles anges i mm2/s. Skillnaden i enhet och mätmetod innebär att standarderna inte kan jämföras rakt av genom resultat och mätvärden mellan de båda standarderna.
Economic impact of fertilizers and improved seeds among smallholder farming systems in Central and Western Kenya
In Kenya, many families subsist on agriculture and of the country's around 40 million residents 70% work in the agricultural sector. 50 % of the country's gross domestic production (GDP) comes from farming, and thus the country is largely dependent on income from this sector. Kenya's population has tripled in recent decades, which have led to that food availability is a growing problem.
To ensure food security, it is important that the return from crops increases. The aim of this study is to evaluate what impact the use of fertilizers and improved seeds has for farmer?s economic situation and income generation.
Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes
Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest
components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this
study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.
Produktivitet vid selektiv mekaniserad bioenergiröjning av eftersatta röjningsbestånd :
In Sweden, harvesting pre-commercial thinning (PCT) stems for energy purposes is a interesting way of financing the high cost of preparing dense stands for a profitable first conventional thinning. This concept can be labelled bioenergy thinning.
The aim of this study was to quantify the productivity of a Vimek 404R light harvester with an accumulating Naarva-Grip cutting head during the bioenergy thinning of a self-regenerated stand west of Sunnansjö in Dalarna. The stand was birch-dominated, contained 15 371 stems/ha, and measured on average 4,6 cm Dbh and 7 m tall. Even though the driver was well experienced with the machine, the stand in question was the first one that he ever thinned in this manner. Nevertheless, the driver strived to accumulate as many stems as possible during each crane cycle and chose to cut taller stems in half so as to make the handling and forwarding of the harvested stems easier.
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.
How to future proof a Business Model : Capture and capitalize value in the field of Urban Mining
Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.
Jacobsberg - Lustträdgård och begravningsplats : En dokumentation, trädgårdshistorisk studie och funktionsanalys
This essay, Jacobsberg ? a Landscape Garden and a Cemetery is a documentation and a historical analyze where I?ve been focusing on the development of the landscape garden in Sweden in relation to a garden called Jacobsberg. The garden was built close to Visby on Gotland in the early 1800s by the assessor Jacob Dubbe, but has since been almost forgotten. My survey aims to depict the circumstances surrounding the creation of Jacobsberg. In what purpose was it built? I?ve also been examine the historical context of the garden?s origins with the intention to define and confirm its architectural style.The essay comprises two major parts, where the first part deals with the history behind Jacob Dubbe and Jacobsberg, and contains an illustration of the assessor?s life and of the garden?s original structure and shape.
Kroppssammansättning, energiomsättning, substratutnyttjande och insulinkänslighet hos barn med övervikt och fetma
IntroduktionÖvervikt och fetma är ett växande folkhälsoproblem i stora delar av världen, problemet kryper dessutom allt längre ner i åldrarna. Övervikt hos barn ger en betydligt ökad risk att som vuxen drabbas av tillstånd som diabetes, hjärt- och kärlsjukdomar, vissa cancersjukdomar samt en ökad risk att dö i förtid.SyfteSyftet med studien var att undersöka om det föreligger skillnader i kroppssammansättning, energiomsättning, substratutnyttjande och insulinkänslighet mellan könen hos barn med övervikt och fetma i åldrarna 10-13 år, samt om det fanns några skillnader inom könen utifrån kategorisering efter BMI för övervikt (25-29,9) respektive fetma (?30). MetodDatainsamlingen skedde genom inhämtning av resultat från mätningar av kroppssammansättning, energiomsättning, substratutnyttjande och insulinkänslighet utförda på ett universitetsjukhus i Mellansverige under åren 2008-2014. Resultatet hämtades från 26 flickor och 29 pojkar med övervikt och fetma i åldrarna 10-13 år. ResultatDet förelåg ingen signifikant skillnad avseende något av mätvärdena mellan könen. Det kunde dock ses en signifikant skillnad avseende insulinkänslighet mellan de med övervikt och fetma hos båda könen, hos pojkarna fanns det även en signifikant skillnad i energiomsättning (p=<0,05).

Flavour improvement of water solutions comprising bitter amino acids
The aim of this project was to improve taste of a liquid food product, comprising extremelybitter and unpalatable amino acids and one unrevealed ingredient. The amino acids were Lleucine,L-isoleucine, L-valine, L-threonine and L-lysine monohydrochloride. Experimentaldesign was set up as a screening of water solutions comprising these ingredients (called BCAAsolutions) and added ingredients with potential to improve flavour. BCAA solution withingredients that were potential bitterness suppressors were evaluated in flavour, bitternessand/or palatability. Solutions of separate amino acids were also studied.
Agricultural and forestry business owners? perceptions of banks
Over the course of the past the agricultural sector has been characterized by radical market changes. Changing market conditions have forced owners of agricultural and forestry businesses to make further investments. This increase in investments has led to a greater need for external capital, which has increased the relationship between banks and owners of agricultural and forestry businesses. The financial sector is characterized by strong rivalry, which forces banks to create strategic positions in the financial market. Since agricultural and forestry businesses are generally seen as secure customers by banks, due to high property and land values, the competition between banks with agricultural and forestry businesses as customers has amplified.
Faktorförsökbaserad diskret händelsestyrd simulering av trafikflöden under långsiktiga prognoser: En fallstudie vid Göteborgs Hamn
Världshandeln växer kraftigt och det vanligaste sättet atttransportera gods mellan landsgränser är genom sjöfart. I takt med attvärldshandeln växer, ökar också storleken på fartygen. Detta innebär att enstörre mängd gods anländer samtidigt när ett fartyg förtöjer vid en hamn. Föratt hantera denna ökade mängd gods måste godsnav och hamnar ständigt utvecklaoch effektivisera verksamheten. Detta innebär att långsiktiga prognoser ochplaner måste utvecklas för hur större fartyg skall kunna hanteras.

Lätt och rätt, så blir kunden mätt - Kanalval och kontaktytor i kundresan för dagligvaruköp
The use of digital devices are widely spread among us. Children have an iPad in their hands before they learn how to talk and we bet you look at your smartphone more times a day then you would like to admit? Interaction through these devices have become so natural in our daily life that we get confused when a retailer does not offer a website or an app. The habit of searching for information in the most accessible channel and buying in the one that offers the benefit of convenience, and of course, saves you money and time, is a common way of shopping these days. This is referred to as multi-channel shopping.
