Experimentell studie av sensationen hos färger

There are a large number of studies on colour and its influence on human feelings, but thereare only a few studies on the association between feelings and colour combinations. Thisstudie investigates the association between colour combinations consisting of three equallysized colours and the feelings they convey. The methodology used in this studie follows theinstructions from the Nippon Colour & Design Research Institute (NCD) in Japan, NCD havestudied consumer psychology towards colour and colour combinations for several decades.This study used semantically differential scales to evaluate existing colour combinations fromNCD to descriptive adjectives and creation of new colour combinations to explore therelationship between colour combinations and conveyed feelings. A total of 69 peopleparticipated in the tests. The main conclusions formed by this study are: (1) the feelingsconnected with the colour combinations differ partly between the Swedish population and theNCD and (2) the Swedish population have similar feeling associations to most colourcombinations, except for trend dependent adjectives such asmodern, cool etc.

Samvård respektive separerad vård : Inverkan på en nybliven mors tillit till sin förmåga att amma

På de flesta svenska sjukhus har samvård av mor och barn efter förlossning eftersträvats eftersom samvård bland annat främjar amning. I samband med kejsarsnitt och då barnet inte mår väl efter födsel separeras dock ofta mor och barn för en kortare eller längre tid, vilket påverkar amningen negativt. Mödrars tillit till sin förmåga att amma har visat sig ha stor betydelse för om de skall lyckas med amning. Mödrar med låg tillit har en högre risk att sluta amma tidigt än de som har hög tillit. Syftet med studien var att jämföra nyblivna mödrars tillit till sin förmåga att amma då mor och barn vårdas tillsammans respektive vårdas separerade efter förlossning.

Effects of biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.

Opera i Stockholm, Stadsgårdskajen

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..

Målgruppsanalys inför en samhällsintervention riktad till förskole- och skolbarn: Intag av livsmedelsgrupper som utgör fokus i interventionsåtgärder

Denna kartläggning ingår som en del i ett större forskningsprojekt, Idefics (Identification and prevention of Dietary and Lifestyle?induced Health Effects in Children and Infants) som har tagits fram för att förebygga övervikt och fetma bland barn mellan 2?4? och 6?8 år i Europa. Syftet med vår kartläggning är att utifrån ett stickprov bestående av 100 barn ur Idefics population kartlägga livsmedelsintag. Detta som underlag för deras kommande intervention där två av nyckelbudskapen är att öka konsumtionen av vatten samt frukt och grönsaker. Även skillnader i livsmedelsintag mellan interventions? och kontrollgrupp, flickor och pojkar samt förskole? och skolbarn studeras.

Larmbolagets webbplats : En studie om skapandet av en tillgänglig och användbar webbplats

This paper accounts for the work with a website for a company whose real name will not be disclosed in the text of this paper. Instead, they have been assigned the fictitious name Larmbolaget, which can be translated as ?The Alarm Company?.During our work with Larmbolaget?s website, we consulted a selection of accessibility guidelines from the Web Content Accessibility Guidelines (WCAG) 2.0, developed by a working group within the World Wide Web Consortium, as well as a number of design principles and heuristics outlined in this paper. We also conducted several usability tests on users from our intended target group. All the measures taken were an effort to ensure that Larmbolaget?s website be as accessible and usable as possible.Our conclusion is that the resulting website does comply with the accessibility guidelines and design principles described in this paper, and thus we consider it to be accessible and usable to a wide range of users, including those with disabilities..

Bakgrund. Forskning har visat att få barn, vuxna och ungdomar når rekommendationerna gällande frukt- och grönsaksintag, fysisk aktivitet, skärmtid och regelbunden måltidsordning. I Sverige finns inga rekommendationer för skärmtid men i Kanada rekommenderas skärmtiden till max två timmar per dag. Forskning har visat tendenser till att skärmtiden ökar, samt att fysisk aktivitet och frukt- och grönsaksintaget minskar med stigande ålder.Syfte. Syftet med studien var att undersöka graden av fysisk aktivitet, skärmtid, måltidsordning och intaget av frukt och grönsaker hos gymnasieelever i Umeå.Metod.

Goodwill och Marknaden: En studie av relationen mellan goodwillnedskrivningar och investerare

Following the implementation of IFRS with yearly impairment tests, the question of correlations and causalities between impairments and investors? decision making is gaining interest in academia. This essay will study the relationship between significant goodwill impairments, communicated on the Nasdaq OMX Stockholm webpage between the years 2005-2009, and the impact those announcements have had on investors? decision making. Furthermore, the causality behind the impairments will be in focus.

Energi och näringsintag hos studenter på handelshögskolan vid Umeå universitet : En tredagars kostregistrering

Bakgrund Intaget av mättat fett är högt hos Sveriges befolkning och intaget av fibrer, järn och D-vitamin har minskat på senare tid. Kostvanor och livsstil påverkar hälsan och risken att drabbas av folkhälsosjukdomarna; hjärtkärlsjukdom, diabetes, benskörhet, metabola syndromet och cancer. För att minska risken att drabbas av folkhälsosjukdomar är det även viktigt att minska stillasittande. Civilekonomstudenter är en grupp som traditionellt sett har ett stillasittande arbete. Det är därför viktigt att belysa hur närings- och energiintaget ser ut för denna grupp för att kunna motverka ohälsa i ett tidigt stadie.Syfte Syftet med studien var att undersöka om civilekonomstudenter vid Umeå universitet uppnår det genomsnittliga behovet (AR) och Nordiska näringsrekommendationer (NNR) gällande närings- och energiintag.Metod Metoden som användes var en tredagars kostregistrering.

This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Påverkan av skogsbrand på litiska arkeologiska fynd ? experimentell simulering av brand

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

Postoperativ smärta och illamående vid behandling med Dolcontin/Depolan/Morfin och Oxycontin/Oxynorm : En jämförande studie

Syfte: Syftet med denna studie var att jämföra graden av smärta och illamående hos två patientgrupper inom ortopedi som smärtlindrades med tablett Dolcontin/Depolan/Morfin eller tablett Oxycontin/Oxynorm postoperativt dag 0, 1 och 2. Syftet var även att undersöka vilka riskfaktorer enligt Apfel Risk Score som kan påverka grad av illamående samt att undersöka om en korrelation fanns mellan preoperativ information och incidensen av postoperativt illamående och kräkning (PONV).Metod: En komparativ studie med kvantitativ ansats. Data samlades in genom två olika enkäter, varav en enkät fylldes i av patienterna och en enkät av sjuksköterskorna. 48 patienter inkluderades i studien, 24 per substans. Både kvinnor och män som genomgått elektiva knä- eller höftarteroplastikoperationer deltog i studien och de var mellan 31-77 år.

Filosofi och litteratur : en studie av förhållandet mellan filosofisk litteratur och skönlitteratur och dess betydelse för kunskapsutveckling ur ett didaktiskt perspektiv.

What is the relation between literature and philosophy and what can we learn from it? Is there something about the novel and its language, fiction and narrative that separates it from philosophical litterature? In what way is knowledge about this useful to us, and is it possible to use fiction for the understanding of philosophy?This study makes an attempt to shed some light on the by no means obviuos distinction between philosophy and literature. The aim is to understand what, if in fact there is something that separates philosophy from literature, there is about the distinction that makes it possible for us to separate the ideas in literature from philosophical ideas, and in what way we can use the novel, or fiction in its widest meaning, to understand philosophy. When teaching philosophy you´re often required to make the abstract tangible. But if there´s a misconception about the distinction in what makes philosophical literature philosophical, then maybe there is something to learn from literature, or, at least, something about the fiction and its aesthetics, that makes it easier for us to relate to and understand, for example, the theories that are debated in moral philosophy.There are some philosophers who have used the form of fiction to make their thoughts on philosophical questions understandable.

Att hantera sömmar i interaktiva system

The purpose of this paper is to examine how seams in an interactive system should be managed. Seamsin this study refer to the boundaries that arise when users move between for example differentsoftware, products or positioning systems. These seams are a cornerstone of the relatively unexploredarea called seamful design, which is based on that users can avail highlighted seams through activeparticipation in the use of a system. To analyze this area, seamful design is applied to the developmentof an interface of a smoothie vending machine. This smoothie machine thus provides the analyzedinteractive system, which the research questions are applied to as well as answered by.
