This study has investigated the usage of rescue chambers as an alternative to additional egress paths. The new underground facilities at CERN that are planned as a part of the HL-LHC project have two proposed designs with rescue chambers or additional egress paths. This report consists of two parts, a case study of the proposed designs for CERN and a literature review on rescue chambers. The resul

Klimatförändringar kommer att göra det svenska klimatet både varmare och blötare. Det kommer att leda till en ökad nederbörd. Parallellt med klimatförändringar flyttar allt fler människor till städer. Detta sätter stor press på att samhällsutvecklingen tar hänsyn till både klimat och ökad inflyttning för att minska risken och sårbarheten att drabbas av översvämningar. Ett sätt att minska översvämnAmidst the on-going trend of urbanisation, and its notable effect of climate change, there have been calls for a more sustainable management of storm water. As part of this movement, blue-green measures, with their many multifunctional benefits, have been recognised as sustainable solutions. The aim of this study is thus to identify the barriers and drivers in order to facilitate the implementatio

“There is no tool for development more effective than the empowerment of women,” Kofi Annan (UN News Center, 2005). The empowerment of women takes different forms such as pursuit of education, participation in political activities and representation in leadership, equal employment opportunities and wages, access to health care and ability to make decisions on personal reproductive health, economic

Syftet med studien var att undersöka de sexuella samtalens betydelse och funktion i kamratgruppen hos unga heterosexuella män. Totalt genomfördes fem semistrukturerade intervjuer med män mellan 23 och 25 år. En aletisk hermeneutisk metodansats användes och det insamlade materialet analyserades med tematisk analys. Utifrån detta framträdde fyra huvudteman: mycket sex ger högre status, önskan om visThe purpose of this study was to examine the meaning and function of sexual conversation in the peer group among young heterosexual men. A total of five men aged between 23 and 25 participated in semi-structured interviews. Based upon a hermeneutic approach, thematic analysis was conducted and four main themes identified: much sex leads to higher status, wish for certain attention, competition in

Effekter av skogsbränder på kolbalansen i boreala skogar I boreala skogar lagras kol i vegetation och jord, däribland kol av antropogent ursprung. Därav är dessa skogar en viktig del av kolcykeln och regleringen av klimatet. Då skogsbränder uppstår påverkas denna lagring av kol då en del av kolet frigörs vid förbränningen av biomassa. Skogsbränder medför även indirekta effekter, detta då ekosystBoreal forests are important for climate regulation since they store anthropogenic carbon emissions in vegetation as well as in soil. Forests fires might counterbalance this by releasing the stored carbon to the atmosphere. In this review the effect of forest fires on carbon dynamics in boreal forests was examined. More specifically, studies were reviewed estimating the combustion emissions of car

The global food system, population growth, increased wealth, shifting diets and an overall larger demand for processed food, meat and dairy, has led to increased pressure on land, water and energy. The environmental implications of this have taken part in the establishment of international institutions which aims to regulate agriculture production methods, and thereby reduce these adverse impacts.

Labour market outcomes for immigrants in general is a well researched field, but the mechanisms behind labour market mismatches among immigrants post-migration is still in need of empirical research. Using a unique and newly compiled dataset on Swedish immigrants, also containing pre-migration occupational and educational information data, this study aims makes use of maximum likelihood models to

Nationalräkenskaperna, och särskilt BNP, används idag ofta som ett mått på välfärd och välmående i samhället. Dock, i verkligheten är dessa mått inte ämnade att mäta välfärd och även när det gäller att mäta produktion finns det oftast stora problem. Utöver detta uppträder det ofta problem när man ska jämföra nationalräkenskaperna mellan länder eller olika tidsperioder. Under den tidsperiod jag anThe national accounts, and specifically GDP, are often taken as a measure of welfare and increased wellbeing in society. However, in reality these measures are not created for measuring welfare, and even in measuring productions there are often significant problems. Furthermore, problems arise when we try to compare national accounts between countries, or between different periods. During the dec

The aim of this project was to examine if it is feasible to develop and apply a reuse concept regarding clean in place (CIP) processes. The concept is based on different topics such as lim-itation, structure, future and reliability. Three CIP processes were chosen to represent the wide variety of cleaning processes available to the food and pharmaceutical industries, Single use Food, Recovery Food

Solkräm – en miljöfara? Solskyddsprodukter används i allt större utsträckning för att skydda oss mot bland annat hudcancer. Vi informeras ständigt om vikten av att smörja oss med solskydd för att undvika skador på huden. Vad som däremot inte informeras om är att vi samtidigt bidrar till stora utsläpp av kemikalier som kan ge negativa effekter för livet i sjöar och hav. Solvårdsprodukter såldes The aim of the study was to perform a hazard assessment of ingredients in sunscreen products available on the Swedish market. Data was collected by documentation of all ingredients in 110 frequently occurring sunscreen products from 15 different brands and by a screening of four known databases for collection of hazard classifications of the ingredients. The study shows that 96 out of 347 ingredie

In the past century, Sweden has seen vast developments in narrowing the gender earnings gap between men and women. Nevertheless the gap still remains, and has revealed patterns of stagnation in the recent decade. In the presence of a gender earnings gap there is an unequal distribution of economic power between men and women, which may lead to an inefficient resource allocation. Today there is a l

This study focuses on the fact that women and men often are treated differently in both society and court negotinations. The Care of Alcoholics and Drug users Act (Lag 1988:870 om vård av missbrukare i vissa fall) in certain cases give society a possibility to intervene when a person with addictive problems can’t break the addicition themselves. The main aim of this study is to examine if norms ba

Eutrofiering det oönskade fenomenet av hög näringstillförsel i ett akvatiskt system, är för det mesta ett resultat av mänsklig påverkan: industriellt och urbant avloppsvatten, avrinning av gödningsmedel från odlad mark, och förbränning av fossila bränslen. Studien av de främsta faktorerna som bidrar till eutrofiering (t. ex. variationer i kvävets kretslopp), är viktigt för förståelsen av dess negaEutrophication, the undesired phenomenon of high nutrient loads in an aquatic system, is mostly caused by human impact: industrial and urban waste water discharge, run-off of fertilizers from agricultural use, and combustion of fuels. The study of eutrophications' main participants such as the nitrogen cycle, are necessary to prevent it. Environmental parameters have an impact onto the effecti

Household portfolio choice problem has been in debate for a long time, and it be- comes more relevant nowadays. Substantial works have been done to understand the relationship between labour income risk and risky asset holding, despite that inconsistent empirical relationships are revealed. In this paper, we investigate the age-variant effects of labour income risk on households participation deci

In the global world of today where people are more mobile some urban districts have tensions between groups of people, and urban policy need to find tools to create prerequisites for a positive development in the new city. This master thesis take the creative economy approach to describe and analyse creativity as a tool in urban districts in transition. Creativity has great potential in revitalizi

In this master thesis work, the effect of polarization, at the Base Station (BS) side, on the performance of multi-user Coordinated Multipoint (CoMP) systems is studied. This study was performed using synchronous multi-link measurements that took place at the campus of the faculty of Engineering, LTH, Lund University, Lund, Sweden, where two different BS setups were studied. In the first setup, on

Malware (malicious software) is becoming an increasing problem, as it continuously grows both in numbers and complexity. Traditional, signature based anti-virus systems are often incapable of detecting new, sophisticated malware, which calls for more advanced tools. So called sandboxes are tools which automate the process of analyzing malware by actually running them in isolated environments and o

Idén till det här examensarbetet föddes när vi tillsammans tillbringade en termin i London för snart tre år sedan. Vi bodde nära Hackney City Farm, en stadsbondgård i östra London. Ett stenkast från bullrande vägar och röda dubbeldäckare fanns får, kor, getter, åsnor, höns och grisar mitt i stan. Vi blev berörda och fascinerade av närheten mellan djur och människa i en urban miljö. I vårt examensInitially the idea for this thesis was born when we spent a semester together in London about three years ago. We lived close to Hackney City Farm, in the heart of eastern London. Within a stone’s throw from noisy roads and red double-deckers there were sheep, cows, goats, hens and pigs right in the middle of the city. We were fascinated and inspired by the closeness of animals and humans in a ver

Vår uppsats undersöker hur säkerhetsmedvetna försäkringsförmedlare i ett försäkringsbolag är. De samlar in och behandlar känslig information dagligen och det är då rimligt att anta att det ska finnas en hög säkerhetsmedvetenhet. Vi har tagit hjälp av motivationsteorin Temporal Motivation Theory (TMT) för att bygga vår undersökningsmodell. Efter att ha granskat litteratur har vi identifierat aktivi
