Järnvägen utgör grunden för pendeltrafiken inom region Stockholm och störningar i järnvägstrafiken påverkar många resenärer. En vanlig orsak till störningar i järnvägstrafiken är att obehöriga personer vistas vid spåren. Mellan 2010-01-01 och 2015-05-18 har närmare 1100 händelser med obehöriga vid spår rapporterats i region Stockholm, varav drygt 80 fall resulterat i personpåkörningar med dödligt The railway constitutes the foundation of commuting in the region of Stockholm and disruptions in the railway traffic hence affects a lot of citizens. A common cause of disruptions is railroad trespassing and between 2010-01-01 and 2015-05-18 more than 1100 cases were reported in the region of Stockholm. The aim of this report is to map the grounds for railroad trespassing and to find measures to

BAKGRUND På grund av att företag idag har möjlighet att konkurrera globalt genom att flytta produktionen utomlands och att säkra leveranser ifrån alla världens hörn har också inköpsfunktionens roll förändrats. För att nå företagets uppsatta mål är det viktigt att ha en välfungerande inköpsfunktion som jobbar effektivt. Inköpsfunktionen bör inte enbart fokusera på att uppnå det billigaste möjliga iBACKGROUND Through global competition with possibilities for companies to set up production and to secure supply from all over the world the role of purchasing has increased within businesses. In order to achieve business results, a well-working purchasing department plays an important part. To contribute, the purchasing function should not only focus on getting the cheapest price possible, but to

The aim of this study was to examine how people who live in supported housings for active addicts shape their life stories based on their current geographical and social position. And how their stories can be understood in relation to prevailing political discourses on homelessness and substance abuse. A combination of unstructured life story interviews and ethnographic methods where used to colle

This thesis investigates and numerically solves the Wohlfart-Arloch equations describing the electrical activity in the atrial part of the heart. This is done through operator splitting that is allowing the diffusion of ionic currents, and the local voltage-driven reactions in each cell to be de-coupled. The local reactions can be solved in closed form, and the diffusion part is solved with a spec

”Vårt samhälle blir alltmer sårbart” är säkert en formulering du känner igen. Faktum är att vårt samhälle är fullt av risker, stora som små, och för att minska dessa gör varje kommun en risk- och sårbarhetsanalys. Analysen ska bland annat hjälpa politiker att ta beslut om åtgärder som kan minska samhällets risker och i denna artikel ställer vi oss frågan om detta faktiskt händer? Risk definieras iThis thesis examines to what extent the comprehensive municipal risk and vulnerability analysis work as a basis for decision-making concerning risk and vulnerability reducing measures in eight Swedish municipalities. An additional objective is to identify mechanisms influencing the decision-making process regarding such measures. In order to meet these objectives an interview study was conducted i

In this essay I have studied the video game Mass Effect franchise as an intermedia and transmedia phenomena. For the analysis of the empirical material I have adopted media scholar Henry Jenkins’ concept of transmedia storytelling. The purpose of this paper is to show how transmedia storytelling can appear around the 2010th century. To do so I have mapped out the different Mass Effect products in

Agile software development promotes process adaptability throughout the life cycle of a project. A project is often broken down into smaller tasks and each task involves a cross-functional team working with all functions. There are many different agile methods, which focus on different aspects of the software development life cycle. Two of these agile methods are Kanban and Scrum, which focus on m

Att äta eller att inte äta? Vi människor utsätts varje dag för olika stressfaktorer. Det kan vara allt ifrån att skriva en skoluppsats till att inte veta vad man ska laga till middag. Överlag är det väldigt olika och väldigt individuellt vad som gör just dig stressad. Det beror helt på vilket liv du lever, vilka intressen du har och vad du prioriterar. Men i djurriket fungerar livet inte riktigt To find out what stresses the markhors, Capra falconeri, at Nordens Ark the herd of five female individuals have been observed during four hours per day for 10 days. In the wild these animals live at high altitudes of the Himalayan Mountains and are excellent climbers with impressive horns that can grow up to 160 cm. The aim was to find out if the zookeepers had a stressing impact on the herd, and

Ju varmare väder desto mer kläder - Hur man föder jordens befolkning Vår planet ökar stadigt i befolkning samtidigt som klimatet blir varmare och skördarna sämre. När de fattiga bönderna inte kan överleva på sina grödor flyr de in i överbefolkade städer utan möjlighet till nya jobb. Fattigdom och svält är ett av de största hotet mot mänskligheten. Terrorgrupper rekryterar framgångsrikt bland den The wax on the stem and leafs of the barley (Hordeum vulgare L.) plant has a protective function and is produced by the cells on the plant's outer surfaces. There are several available barley mutants where the wax production has been stopped. Four mutants are the single-site mutants cer-c.36, cer-q.42, ceru. 21 and the deletion mutant cer-cqu.724. We phenotyped 636 barley plants and collected

This thesis examines three Thai NGO's in the form of homes for children built in the aftermath of the 2004 Tsunami disaster. The purpose of the study was to examine the relationship between, on one hand, strategies used by the homes in order to obtain resources required to further continue their operations, and on the other hand, the explicit objectives of the homes to care for and protect the

The Australian Bogong moths are thought to have the ability to sense the earth’s magnetic field. This ability has to be reflected in the animal’s neural architecture. Hence reconstruction of three brain neurons was carried out, though these respond to visual stimulation instead of magnetic. These reconstructions were compared to that of other known specie’s visual responsive neurons to provide a b

Wax production is essential for the survivability of Barley (Hordeum vulgare) plants. They use it to fend off bacteria, viruses and helps rinse the cuticular surface from dirt. Much research has been done regarding the genetic regulation and the cer-cqu genes are proven to account for the biosynthesis of wax. A point mutation has been induced within the cer-u region which gives rise to waxless pla

Every summer the Australian Bogong moth migrates from southern Queensland to the Australian Alps in southern New South Wales. Other migrants such as the monarch butterfly use a time-compensated sun compass. However, the Bogong is nocturnal and only has access to skylight cues such as the moon, polarized light or the Milky Way. Since these are considerably unreliable only being visible short period

This thesis introduces different issues regarding the impact of anthropogenic sound pollution on oceanic cetaceans (whales). It involves looking at the problems of anthropocentrism and the notion of Umwelt when trying to assess the well-being of a western culturally important species, and the relationship between that species and the industrialization of the ocean. The thesis is specifically focus

Since independence in 1957, Malaysia has transformed significantly from an economy based on primary commodities to one fuelled by manufacturing and services based on foreign investment.. Besides Malaysian economy has achieved steadily high growth for over five decades. However, after the Asian financial crisis of 1997, the growth of Malaysian economic slowed and the downturn remains until the 2008

After years of neglect, Lebanon is facing the consequences of a struggling water sector. Existing water networks are deficient; water supply continuity is low; most wastewater is discharged into rivers or the Mediterranean Sea without adequate treatment; and inter-agency coordination remains weak and fragmented. In 2000, the government together with international donor agencies initiated a reform

I takt med att jordbruket har intensifierats har arter anpassade till det gamla kulturlandskapet trängts undan, vilket hotar den biologiska mångfalden. Ledningsgator har på senare tid uppmärksammats för sitt värde som ett alternativt habitat för dessa arter och energibolaget Kraftringen vill arbeta för att främja mångfalden i sina ledningsgator. För att utreda vilken biologisk mångfald som finns i

Semi-natural pastures are one of the most species-rich habitats found in Sweden and many endangered species are connected to them. Strongly declining in area, semi-natural pastures in Sweden can be eligible for financial support within the EU agri-environmental scheme. The definition of pastures eligible for the scheme was changed in 2008, more specifically the amount of trees and bushes was restr

The environment surrounding us affects our sense of ourselves, although it isn’t something static or permanent, but rather predetermined by our perception. What we wanted to explore with this study was how men were influenced by their environment in relation to their identity development, and in what way they felt social pressure from the society. Therefore our purpose of the thesis was to investi
