Populärvetenskaplig sammanfattning av examensarbete utfört vid institutionen för byggvetenskaper vid LTH i samarbete med Sweco Civil AB. Under vissa förhållanden kan sugkrafter uppstå i jord. Fenomenet är sammankopplat med hur mycket vatten det finns i marken, desto mindre vatten desto högre sugkraft och därmed mindre risk för att t.ex. jordslänter rasar. För att undersöka detta fenomen har finiIn this master´s dissertation I investigated if it is possible to increase the total stability for excavations in clay, if suction is taken into account during the calculations. The work has been performed at, and in cooperation with, Sweco Civil AB as well as the Dept. of Construction Sciences at Faculty of Engineering LTH, Lund University. The objective of this master´s dissertation is to asse

Crowdfunding is a financing method based on raising smaller funds from a large audience over the internet. The data used in this quantitative study includes all 1080 reward and equity campaigns uploaded on the Swedish crowdfunding platform FundedByMe from 2011 to 2015. I aim at providing evidence of what factors that influence the success rate of crowd- funding campaigns. To answer this, I have ru

After the outbreak of the financial crisis in Europe in 2008, the strategies to antagonize its con-sequences, involved the implementation of internal devaluation policies such as nominal wage suppressions. The effectiveness of these policies has undergone various studies with rather negative criticism and evaluation. To produce further research and perform an empirical analy-sis in this field, thi

The movement of carbon on Earth is based on exchange between pools that represent carbon in different physical forms, differing in chemical composition, structure and function. Dissolved organic carbon plays an important role in ecosystems because of its mobility, which can be relatively high in saturated soils, and because it is the most available fraction of organic matter for microorganisms in

Can differences in institutional quality explain current account imbalances in the Euro area? This paper emphasizes a link between current accounts and institutional quality based on a country study for Greece. Subsequently it tests the relationship for a homogeneous sample of 24 European countries over the period 1990 through 2013. Regression analysis indicates that institutional quality is cruci

This project was initiated by the food technology department of Lund University for a design study of a new developed technology to dry mashed fruits. A fabric with special parameters allows to preserve fruits, without using electricity, in a short period of time. The given task consists of designing a “bag” to dry mashed and liquid fruit purée. The bag should be easy to fill, empty, clean and re-

Mitigation of greenhouse gas (GHG) emissions is essential for us humans to curb climate change. Around a fifth of the anthropogenic GHG emissions stem from the construction sector. Much come from energy used for space and water heating within buildings, but an increasing proportion comes from the manufacturing of the building materials and is virtually embodied within buildings. This is called Emb

Clarias gariepinus has huge economic and nutritive value in Cameroon but yet it is not widely cultivated. The purpose of this study was to test the effect of water quality and water exchange (which are some factors that affect fish growth) on the growth and survival of this species along the Mt Cameroon region. An experimental setup was used in the lab of the University of Buea campus to emulate

Background: An increasing number of older persons are living in their own homes with complex illnesses. Therefore the demand for more and advanced nursing at home is increasing. District nurses (DN) in home nursing care delegate a number of tasks to unlicensed personnel (UP), such as wound care. Aim: The aim of this study was to explore unlicensed personnel’s experiences of receiving and having a

I den här uppsatsen diskuteras avtalsrätten och hur den påverkas av offentligrättsliga principer när offentliga aktörer samarbetar med enskilda genom offentlig-privat-samverkan. I fokus ställs det allmännas möjlighet att frånkomma ett avtal där syftet med avtalet inte nås. I uppsatsen görs en sammanfattande genomgång av avtalsrättens fundamenta samt en lite mer utförlig analys av förutsättningslärIn this essay it is examined how the interaction between the regulations regarding public procurement and commercial contract law is causing problems for the public to uphold principles of the welfare state through the regular proceedings of contract law. Focus is set on the possibility that public welfare objectives might not be met by the delivery of health services through private contractors.

In a progressively globalized world the catapults of economic globalization, is in large, due to increased flows of foreign direct investments (FDI) across the world. FDI flows are considered essential vehicles for economic growth and development. The complex entities that embody a multinational company (MNC ) are often simplified to encompass either an exploitation approach of LDCs by MNCs or the

I denna uppsats undersöker jag huruvida BRIC-marknader bör inkluderas i en aktieportfölj som ursprungligen består av OMXS30 indexet. Vi utgår ifrån perspektivet av en Sverige-baserad investerare som vill hitta diversifieringsalternativ till sin svenska aktieportfölj. Vi använder en metod där korrelationer och standardavvikelser för BRIC-ländernas avkastningar undersöks. Sedan skapas sex portföljer

SCB uppger att bland tidsbegränsat anställda känner 40 procent en oro över hushållets ekonomi (SCB 2014, s 28). Ekonomiprofessorn Guy Standing (2013) menar att flexibiliteten på arbetsmarknaden och arbetsgivarnas förväntningar medför en oro och de ”prekära anställningarna” som också bidrar till klassen som benämns som prekariatet. En klass som han anser vara en ekonomiskt och arbetsrättsligt försv

Most of the natural resources we rely on for our existence on this planet could in one way or another be a subject to overexploitation through tragedy of the commons. Tragedy of the commons occurs when rational individuals all acting in their own self-interest creates a situation that is suboptimal for everyone involved (Hardin, 1968). For long privatization or government control over a common wer

I takt med att jordens befolkning växer ökar samtidigt den totala efterfrågan på mat. Större press sätts på jordbruket att se till så att man kan möta denna efterfrågan och försörja en större population. Men det räcker inte enbart att kunna producera så mycket mat som man kan, det ska samtidigt göras på ett så ansvarsfullt och hållbart sätt för miljön som möjligt. Jordbruket har hittills varit beThis report summarizes the advantages and disadvantages of organic and conventional farming from an environmental and sustainable perspective. A sustainable agriculture system needs to be able to meet a higher demand for food due to a growing population and minimize the damage of the environment at the same time. The main critic to the organic farming system is that it produces lower yields than

The main purpose of this report is to identify, evaluate and if possible, suggest reduction methods to the risks from which users at the beamline BALDER, MAX IV Laboratory are exposed to during their visit. Identified risks includes radiation, fire, electricity, gases and miscellaneous risks such as the overhead crane. The evaluation indicates that the handling of toxic gases inside the experiment

Anknytning mellan spädbarn och föräldrar är en naturlig process som sköter sig intuitivt och kan stödjas av BVC-sjuksköterskor. Syftet var att beskriva BVC-sjuksköterskors upplevelse av anknytning och gott samspel mellan spädbarn och deras föräldrar samt hur anknytningen kan stödjas. Tolv BVC-sjuksköterskor intervjuades och resultatet framställdes med hjälp av kvalitativ innehållsanalys. Det goda

The term 'Object Shift' means that a weak object pronoun has been raised to a position to the left of a sentence adverbial. In Swedish, there are mainly two positions to which a weak object pronoun can be raised; one of them is called 'Long Object Shift' or 'LOS'. In this paper, I deal with argument structures in constructions with LOS in Old Swedish. The purpose is to prov

The lack of sources that generates intense THz pulses have in many years limited the field of THz science. Until recently intense THz pulses have been hard to generate using nonlinear crystals such as Lithium Niobate (LiNbO3) with high efficiency. In this thesis a method is presented for achieving short and intense THz pulses through optical rectification using the recently developed tilted pulsef
