The subject of this thesis is theoretical examination of freezing phenomena inside fire sprinkler systems during activation at low temperatures in the surroundings. Many sprinkler systems are installed in environments such that they must be operable at subfreezing temperature conditions. During activation of such a system, water is assumed to penetrate a significant distance and without interrupti
Many aid agencies are working in countries where side-payments is a common problem in the society. This makes it hard for the aid agencies workers to know how to behave in situations where side-payments are expected. Most aid agencies have a strict policy of not using side-payments, but can side-payments ever be justified if they help the aid agencies to achieve their goals? To answer this questio
Bergmaterialindustrin i Sverige befinner sig just nu i en omstruktureringsfas då nya regler starkt begränsar möjligheten att använda sig av naturgrus för så väl bygg- och anläggningsändamål som för betongindustrin. Detta har även lett till att teknikutvecklingen stävar mot en övergång mot krossat berg, och inte sällan har det lett till bergmaterial med egenskaper som överträffar dem för naturgrus.The Swedish rock-mass industry is currently in a transition period because new rules and regulations strongly limit the possibility to use naturally sorted aggregates for construction and concrete purposes. Furthermore, research and development within the industry is more oriented towards crushed bedrock aggregates. Whilst the crystalline bedrock of Scandinavia mostly consists of Precambrian gneis
The increase of complexity of public services in the modern era proposes requirements for the coordination and cooperation between the public sectors. Inter department coordination mechanism is one of the very important part in government management and it becomes a global trend. No matter in the US, Japan, Korea or UK, setting up one kind of special organization to do the coordination between dif
It seems like Swedish municipalities are dominated by beliefs that all citizen participation is good for the development of local democracy. A critic of this certainty is rising among Swedish scholars of political science. However, a critic with an ambition of such generalization is harsh. Different democratic projects contents different qualities and thereby diverse problems in the democratic pro
Skadliga marina arter invaderar idag främmande habitat och ekosystem med en extrem hastighet. Dessa arter har haft en mycket stor negativ inverkan på många sårbara ekosystem runt om i världen och barlastvatten har identifierats som en av de största faktorerna bakom den snabba spridningen. Idag är den vanligaste åtgärden för att lösa problemet att byta barlastvatten ute till havs för att göra sig aHarmful aquatic species are today invading foreign habitats at an unprecedented pace. They have had a large negative impact on many fragile ecosystems of the world and ballast water has been identified as one the major culprits behind their fast spread. Today, the most common remedy used to combat the problem is exchanging ballast water in the open ocean to get rid of any organisms with the potent
Äganderätt är den mest långtgående civilrättsliga förfoganderätten till egendom som kan innehas. Före den 1 maj 2009 har det inte varit möjligt i Sverige att inneha enskild lägenhet med direkt äganderätt trots att detta utgör den vanligaste ägarformen för lägenheter i flertalet EU-medlemsstater. Motståndet mot ägarlägenhetsinstitutet har såväl varit juridiskt som bostadspolitiskt till sin karaktärOwnership to property is the most extensive legal right of disposal that can be possessed. Before the 1 of May 2009 it was not possible in Sweden to hold a direct ownership of a flat despite freehold flats (SW. “ägarlägenhet”) being the most common legal form of ownership to a flat in other EU-member states. The resistance towards this institute has been based on legal as well as political argumen
Denna studie undersöker valda modernitetsbegrepp, inspirerade av Claes Ericsson, och hur de relaterar till utformningen av och praktiserande av elevinflytande vid två gymnasier med estetiska programmet: inriktning musik. Forskningsfrågan lyder: Hur kan likheter och skillnader i elevinflytande mellan två studerade gymnasieskolor med estetiska programmet:inriktning musik, förstås med hjälp av modernTitle: The School in the modern era – a comparative study of student impact. The present study investigates chosen perspectives of modernity inspired by Claes Ericsson, and how these can relate to the design and practising of student impact at two colleges with special music education. The core question of the study is: How can similaritites and differences in student impact between two studied co
I vårt samhälle har produkters utseende och design kommit att bli allt mer viktigt. I takt med denna utveckling har också värdet på design ökat och behovet av skydd för design blivit större. Idag kan industridesign skyddas genom en rad lagar och förordningar på immaterialrättens område. Det skydd som lagstiftaren primärt avsett för formgivning och design är dock det mönsterrättsliga skyddet. I denIn the society we live in today the design of products has become more and more important. This development has resulted in an increased value for good design and the need for protection of design is now even more important than before. Industrial design can nowadays be protected through several types of legislation providing intellectual property rights. The type of protection that the legislator
Popular science summary Ecosystem seasonality in climate models Climate change has a major effect on the timing, intensity and duration of seasonal events in Earth´s ecosystems. These changes may remain undetected when analyzing them on an annual scale, as current climate models usually do. Therefore it is necessary to investigate the impact of ecosystem seasonality on climate processes to impr
The purpose of this study was to describe and analyze how the Lund municipality works with crime prevention with youths. To perform the study, we interviewed seven people from five different organizations and authorities with different professions and work assignments in Lund municipality. The people we chose were two social workers, one police commissioner, two fieldworkers, one psychologist and

Traditional measurements for determination of aboveground biomass (AGB) are widely used in ecological studies. However, they are labor demanding and time consuming, why this study performed on a grassland in Senegal has focused on finding a simplified AGB estimation method that could be applied on larger areas in the Sahel. The brightness values in the visible spectral range of digital camera imag
As people travel more than ever before, transport and infrastructure is growing in all Swedish cities. With growing emission levels of nitrogen dioxide, greenhouse gases and particles, and an increasing risk of traffic-related accidents, parking strategy is a key component in planning and securing the healthy development of the city's infrastructure. For new construction and rebuilding a parki
A fire barriers are widely used in the industry as a passive fire protection system. Fire barriers are built according to specifications from manufacturer after the construction was tested in full scale furnace in accordance to the appropriate codes. Those tests are made private and the test results are not published apart from the failure/success of the tested sample. In order to accurately prote
För att klimatförändringarna inte ska bli för stora har Sverige som mål att till år 2020 reducera utsläppen av växthusgaser med 40%. För att klara detta arbete behöver Sveriges kommuner hjälpa till med lokala mål och åtgärder, och Ängelholms kommun har då valt att i sin miljöplan bestämma att kommunen år 2021 ska vara helt fossilbränslefria i alla transporter som kommunen äger eller brukar. SyftetSweden has a goal to reduce the emissions of greenhouse gases with 40 % until 2020 to prevent the climate change from becoming too big. Too succeed in this work, the Swedish municipalities need to help with local goals and arrangements. The municipality of Ängelholm has chosen to decide in its environmental action plan that the municipality by 2021 is going to be completely free of fossil fuels in
Förhöjda temperaturer på höga breddgrader kan förändra koldynamiken i hela Arktis. Modellerade CO2 simuleringar visar att under nuvarande klimatförhållanden utgör Arktis en netto kolsänka, fast den stora utsträckningen samt fina geografiska heterogenitet lyfter upp osäkerhet kring dess status som CO2 sänka/källa i regionen. Förståelsen för arktiska koldioxidflödekan förbättras genom integrering avIncreased temperatures in high latitudes may alter the carbon dynamics throughout the Arctic. Modelled CO2 simulations show that current climate conditions constitute the Arctic a net carbon sink, though the large extent and fine landscape heterogeneity raise an uncertainty about the carbon sink/source status of the region. The understanding of Arctic CO2 fluxes can be improved through integration
Skåne faces great challenges for young people entering the labour market. The challenges include problems for unemployed and employers to meet. Furthermore, another challenge is all about low educational tradition. Last year (2015) Region Skåne started up a project called 1+1=3, where the aim is to work between administrations to get a better overview on how to tackle the challenges. This study is
