LiDAR-bildanalys av flutings i södra Norrbotten : Kartering och datering av avvikande isrörelseriktningar

The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). Analysis of the new high resolution elevation model (2 m grid) derived from laser scanning was performed after treating the data with a hillshade tool in ArcMap to reveal terrain features such as flutings. The analysis resulted in a map showing four main groups of deviating ice flows (N-S, NO-SV, SO-NV and S-N) and several westerly ice flows. The majority of flutings with deviating ice flows were found in low terrain.

Ekoanalys-modell : En förenklad modell för att kunna belysa miljöpåverkan redan i designstadiet av en produkt

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus

The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.

Att färdas i symbios : ett gång -och cykelstråk anpassat efter trafikanternas rörelsemönster och behov

The aim of this paper is to examine the layout of public spaces and its effect on human behavior with focus on the relation between pedestrians and cyclists movement patterns in a specific path. The study emanates from the security aspect of pedestrians and cyclists, and builds upon previous theories and empirical studies about perception, security, information design, environmental psychology and behavior. The result shows that individual behavior and movement pattern differs with age, purpose, physical- and other conditions, and layout of the surroundings. A design proposal for improved layout of a path and a node between different oncoming paths has been developed to aid the users? needs, where a separation of walkways and bike lanes forms zones of security for the purpose of better orientation and a better flow between the users..

Från Tahrirtorget till ett(o)demokratiskt Egypten? : -Demokratins förutsättningar och utmaningar i Egypten, efter den arabiska våren 2011

The aim of this bachelor thesis is to through a theoretical analyze, investigate the conditions and the challenges for a consolidated democracy in Egypt from 1952 until after the revolution of 2011. The central question in this thesis is what opportunities and challenges are there for the democratic consolidation in Egypt, with respect to civic, political and economic conditions. How have the conditions developed between 1952 and 2011? How has the transition government/military government handled the central problems in the transitions phase after 2011? The theory used in this analysis is Linz and Stepans famous five arenas (the political society, the economic society, the civil society, the bureaucracy and the state of rule, whit focus on the three first). Through a qualitative case study we have analyzed the conditions in Egypt from 1952 to after the revolution 2011.The empirical material shows that the arenas in Egypt are both historically and current very weak, and they are not supporting democratic consolidation as they are challenged by several enormous problems.

Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper

The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..

Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm

Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years.    Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed.    Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.

Analys av fysiskt och administrativt flöde för provhantering vid Höganäs AB

In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

The role and influence of the Architect in industrialized building

An emerging trend within the construction industry is the expectation of the customer to experience and sense the product, maybe even in a customized manner. The latter trend would extend the necessity of incorporating not only function and aesthetics, but also perception and sensation. To meet this trend while at the same time improve the productivity the use of information technology such as BIM and technical platforms has increased in construction projects. Nevertheless, in spite of large investments, the construction industry has not managed to increase the effectiveness and productivity as much as other industries. Evident is that successful use of information technology depend on the integration and collaboration of various experts in a continuous and dynamic process.

Flow, motionstid och inre motivation : En enkätundersökning genomförd med tävlingsbuggare

Syftet med denna studie är att bidra till en pedagogisk diskussion om arbetet mot mobbning och trakasserier. Genom att undersöka lärares och fritidspedagogers uppfattning om förutsättningarna att arbeta mot mobbning och trakasserier i samarbete mellan skola och fritidsverksamheten. Studien består av analyser av enkätintervjuer och djupintervjuer med fritidspedagoger och lärare. Avsikten med intervjuerna är att undersöka likheter och skillnader i fritidspedagogers definitioner av och hur de arbetar mot kränkande behandling. Resultatet visar att respondenterna anser att kränkande behandling som visserligen inte ska förekomma i skola eller på fritidshem kan vara svårt och speciellt att använda en övergripande strategi mot kränkande behandling som fungerar.

Enantioselektiv HPLC-analys med kirala stationärfaser bestående av makrocykliska glykopeptider och polysackarider

The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

Multimedia eller inte multimedia, det är frågan.

Is it possible, and suitable, to use multimedia in classic literature studies at Swedish upper secondary school? What alternatives are there?  Is there any foundation in the curriculum for an expanded conception of text as in multimedia?  Will the conception literacy support use of multimedia in classic literature studies, and in what ways? How do we generally look upon the definition text, is it only printed letters, or something more? To get an answer to the questions we decided to examine a number of theories, Gardner?s theory about the different intelligences, the conception literacy and the expanded text concept. In these three theories we took our starting-point for the following work. The main subjects became two interactive sights on Internet and one CD-ROM, all containing classic literature. Our previous knowledge in this subject field was very meager.  This work has given us an opportunity to discover some of the multimedia that is available, and the result we have come to is that multimedia absolutely belongs in studies of classic literature as well as in other subjects.

Externa kanaler på Prime Care : Tanken med dem, dess funktion och sättet de uppfattas på

AbstractTitle: External communication channels of Prime Care How they where thought to be, how they work and how costumers apprehend them.Number of pages: 50 (64 Including enclosures)Author: Sophie DicksenTutor: Peder Hård af SegerstadCourse: Media- and Communication Studies DPeriod: Spring 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The focus of this paper lies on the external communication channels of Prime Care and the aim is to study the following aspects: How do the channels work? How are they apprehended by customers of the company? What are Prime Cares own thoughts behind the channels? How does Prime Cares self-image correspond to the way that customers apprehend the company?Material/Method: Twenty interviews has been done with different customers of Prime Care in order to see how the company and its communication flow is apprehended. A consultant manager of Prime Care has also been asked about purposes behind the companies external communication channels in order to enable a comparison between Prime Cares image and profile. Prime Cares website, one of their mail sendouts, their salescalls, salesvisits and their exhibition participation have been studied on the basis of relevant litterature. Maletzkes model of mass communication was used as a general view of communication flow.Main results: All communication channels included in this study have different ways of function even though they all have the same main purpose, videlicet to promote the company, to inform about its activities and to recruit new customers and consultants.
