BIM, byggnadsinformationsmodellering, är ett arbetssätt som blir allt vanligare. Det innebär att olika objekt bygger upp en övergripande 3D-modell där man kan finna mängder av information om dessa objekt. Ett objekt kan vara allt ifrån en bropelare till en elstolpe. Syftet med denna rapport är att utifrån Trafikverkets roll som beställare undersöka vilka för- och nackdelar det skulle innebära med BIM, Building Information Modeling, is an increasingly common way of working. This means that different objects build up an overall 3D-model where you can find lots of information about these objects. An object can be anything from a bridge pillar to an electric pole. The purpose of this report is to, based on the Swedish Transport Administrations’ as a client, investigate the advantages and disad

Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal

This paper attempts to contribute to existing knowledge through an explicit threefold purpose. Initially, the importance of leverage in explaining equity return volatility is determined through two fixed effects panel data estimations. The panel dataset runs from 1990-2009 and includes 20 years worth of observations for the 45 firms on the Stockholm stock exchange for which data is available. The

As the case of the Deepwater Horizon reveals, the consequences of an oil spill or any other marine incident can be devastating. Although pollution from ships implies a much lesser scale, nevertheless there must be maximum efforts for preventing the possible risks and consequences of marine casualties. For centuries salvors have remained the ones who will provide the fastest response to a ship in

During the latter half of the 20th century there has been a continuous decrease in the number of farms in Sweden and agriculture’s importance in economic terms has fallen considerably. This has had significant effects on economic activity in rural areas, on the environment and on the location and size of the food processing industry. Studying the size and the effects of this structural change in a

I have in this thesis conducted fieldwork at the Swedish newspaper Sydsvenskan's digital media department. I was curious to find out how or if the financial instability that is currently sweeping across the newspaper industry is embodied through praxis within a department that many are eager to blame the instability for – that is, a digital media department. I wanted to pinpoint and observe re

En stor del av Östafrikas landsbygdsbefolkning är självförsörjande jordbrukare som på grund av begränsade markytor och förändrade klimatförhållanden riskerar misslyckade skördar och ökad fattigdom. I takt med att befolkningen växer blir miljöproblem som avskogning, erosion och urlakade jordar, samt övergödning av vattendrag och sjöar alltmer påtagliga. Syftet med den här studien är att kartläggaSub-Saharan Africa suffers from land degradation, depletion of natural resources and rural poverty. In the Lake Victoria Basin, where large parts of the population are small scale farmers, people are facing such issues coupled with altered climatic conditions. The focus area of this study is the Mara region in northern Tanzania, situated on the eastern lakeshore. Mara has experienced a doubling of

Den här uppsatsen kretsar kring svenska kommuners drift av gym, en företeelse som gör att kommunen agerar som aktör på den öppna marknaden. I takt med att allt mer av den offentliga och den privata sektorn har smält samman så har också antalet konkurrenskonflikter som detta kan föranleda ökat. Det privata näringslivet har under årtionden påtalat att de upplever det som ett problem och att den offeThis essay revolves around Swedish municipalities' operation of gyms, a phenomenon that makes the municipalities act as players on the open market. As more and more of the public and private sectors have merged the number of competitive conflicts that this has caused has also increased. The private sector has, for decades, complained that it feels it is an issue and that the public sector is n

Crowdfunding has witnessed growing interest within academia in recent years, despite the underlying motivations for entrepreneur engagement in crowdfunding activities receiving little attention. The purpose of this study is to explore the motives that influence entrepreneurs when using crowdfunding and how these motives are related to each other. This will then provide a deeper understanding of ho

Ever since the dawn of internet, a new wave of fast-growing software companies has emerged. The M&A scholars have struggled to find appropriate valuation mechanisms for unprofitable companies with ultra-high revenue growth. To overcome the uncertain future, a contractual provision called earnout is often used. An earnout is a contractual provision in a M&A-deal that states the seller of th

We present an extensive rheology study of the wormlike micelle system lecithin-water-cyclohexane. In this system the micelles are really wormlike, meaning that there are no signs of micellar branching, as it has previously been demonstrated by NMR self-diffusion experiments (R. Angelico, U. Olsson, G. Palazzo and A. Ceglie, Phys. Rev. Lett., 1998, 81, 2823). Wormlike micelles break and recombine,

The objective of this thesis is to propose a way to introduce social and cultural aspects of environmental degradation to the sustainable development debate. This is done by a reflexive and critical examination of environmental research as it has been applied to different spatial levels (and thus levels of social complexity). The spatial categories discussed are the city, the household and the lan

Coffee production systems are experiencing climate change stress in a multitude of ways. One of the ways in which climate change manifests itself in coffee systems is through the evolution of pest and disease populations. Global coffee production is thereby recognized as vulnerable to climate change, particularly the lives of those that rely on coffee for their livelihoods. Reducing vulnerability

Monapostrukturen ligger i Nampula provinsen i norra Moçambique, och utgör en del av Mocambique bältet. Strukturen är ca 35-40 km i diameter och har en mycket låg topografi. Trots detta syns den väl på satellitbilder och flygfotografier. Relationer mellan samt utbredning av de enskilda bergartsleden är inte helt klarlagd och frågor såsom transportriktning, litostratigrafisk uppdelning samt tektonisThe Monapo Structure is situated in the Nampula Subprovince in northern Moçambique, and makes up a part of the Moçambique Orogenic Belt. It is a 35 x 40 km subcircular structure, with a very flat topography, and it clearly shows up on aerial photos. The regional setting of the Monapo Structure is not yet clearly settled and many questions regarding transportation directions, lithostratigraphic gro

Summary: Lake Bussjö is an 0.3 hectare large kettle hole in a hummocky morain landscape four kilometers north of Ystad. The purpose of this study is to investigate the stratigraphy and reconstruct the highest water level. Another task is to estimate the rate of farmland advance on earlier grazingland and swamps. Furthermore, to calculate the future development of the lake. To make the stratigraphy

Due to the high level of pollutant emissions from traditional marine diesel engines, Liquefied Natural Gas (LNG) as clean energy is becoming a better choice for main engines to replace the traditional fuels. Meanwhile, in order to improve the energy efficiency of the marine power system, the Organic Rankine Cycle (ORC) has been regarded as the most suitable solution to recover the waste heat for t

Objective Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare disease that can result in severe bleeding in a fetus or newborn, including intracranial hemorrhage. Maternal-fetal human platelet antigen (HPA)-1a incompatibility is a prerequisite to maternal HPA-1a alloimmunization, which may result in FNAIT. The risk of HPA-1a alloimmunization is approximately 25-times higher in HPA-1

?SEPARATE WORLDS?. School librarians teaching in information seeking in high school. The aim of this Master's thesis is to study how information seeking is taught in high school and how school librarians describe their experiences of teaching information seeking. Five school librarians from five different high schools (gymnasium) in Skåne participated in the study. The empirical data derives

Diamonds are regarded to be one of the most valuable natural resources on earth, with an average rough diamond price of $71 per carat in 2000. This gives scope for great economic success in diamond abundant countries. Some of the worlds most diamond abundant countries are found in Africa, ironically also some of the poorest. In recent years it has been brought to the world’s attention that illicit
