This thesis presents a study of iron oxide thin films, grown on a silver metal substrate, with the goal of characterizing the structures that form during growth of the first atomic layers. Such ultra-thin iron oxides are interesting model materials for fundamental surface chemistry and catalysis studies. The films were grown by reactive deposition of iron under ultra-high vacuum conditions and cha

Problem: I dagens samhälle har organisationsförändringar blivit allt vanligare och de anses vara allt viktigare för organisationers fortsatta utveckling.

The first aim of this thesis were to analyze China’s discourse of soft power in relation to their investments in the Zambian mining industry from the year 2000 to 2012. From a combination of Norman Fairclough’s critical discourse analysis and Joseph Nye’s soft power theory, I can conclude, that in the 12 years period the Chinese soft power discourse was dominating and China could persuade and attr

During the late 20th century, large parts of the contributions to management theory consisted of concepts on management control systems. The purposes of these were often focused on manual labor and they directed the effort to control employees in order to get competitive advantage, typically through increased productivity (Simons, 1990). Today, however, the focus has shifted from control in labor-

På dagens arbetsplatser används informations- och kommunikationsverktyg i allt större utsträckning. Användningen har, utifrån vissa aspekter, visat sig inverka negativt på de anställdas arbete och på den interna kommunikationen. Tidigare forskning har berört stress orsakad av informations- och kommunikationsteknologi (IKT) men få studier har gjorts för att studera hur anställda upplever arbetet meIn today's workplace, information and communication technology (ICT) have seen an increased use and certain aspects of this use has proved to have a negative impact on employees' work performance and on the internal communication within an organization. Previous research has examined stress caused by ICT, but few studies have been done in order to study how employees perceive their work wi

The theme of this essay is to examine how prophet stories are presented for children. The specific aim is to analyze the narrative structure of two texts presenting the story of Adam. The study uses two Arabic children texts presenting the Story of Prophet Adam (pbuh). The study starts with presenting some theories and their typological frame of narratology and some of their narratological tools,

In today's rapidly changing business environment, organizations strive to be agile in order to accommodate changes and seize opportunities. Since organizations use information system as a tool to serve their needs, it is important for these systems also to be agile. One prominent type of such systems is business intelligence, which provides organizations with information to gain and retain com

This paper will provide different analysis over the Brazilian innovation system, on how it has developed over time, the key features in the system and the next steps in development. In order to better explain the evolution and to evaluate the system, the author will provide systematic, functional, economic, historic and international analysis, based on frameworks proposed by academics in the innov

Bildstyrd strålterapi är en process bestående av att ta 2D eller 3D bilder under strålbehandlingens gång och används för att försäkra sig om att patienten är positionerad på samma sätt som referensbilden för att få samma dos som planerades (beräknat på referens bilden). I det här arbetet har en 3D scanning av patientens positionering jämförs med en CT referensbild för patienten. Efter matchen, somPurpose: The aim of this study is to a) study the benefits and limitations with soft-tissue match for lung cancer patients, b) evaluate five different soft-tissue match methods, c) compare soft-tissue with bony match, d) find the stable surrogates to match on for obscured malignant lymph nodes, e) calculate CTV to PTV and OAR margins and volume of PTV for the corresponding margins, and d) study th

Bröstcancer är den vanligaste cancerformen hos kvinnor i Sverige och står ensam för 30 % av cancerdiagnoserna. Detta innebär att varje dag får 20 kvinnor beskedet att de har drabbats av bröstcancer. Idag får ungefär 50 % av alla cancerpatienter strålbehandling och på strålbehandlingsavdelningen vid Skånes universitetssjukhus (SUS) behandlas flertalet bröstcancerpatienter dagligen. Vanligast är aBackground and purpose: Post-operative adjuvant radiotherapy of left-sided breast cancer patients is associated with cardiac and pulmonary complication. By utilizing different respiratory gating techniques the absorbed dose to the heart and lung can decrease. The purpose of this study was to evaluate and compare enhanced inspiration gating (EIG) and deep inspiration breath hold (DIBH). The use of

This study describes the safety culture at Lund University School of Aviation (LUSA) at two occasions, separated by a period of approximately one year, and the effects of the interventions that were carried out during this year. The study was conducted by means of two attitude measurement surveys with interviews after the first survey and opportunities for the respondents to propose improvements a

East Asia has experienced a substantial decline in fertility over past few decades. Japan and Korea touched lowest level of fertility, which is 1,26 and 1,08 children per woman respectively in 2005. However, Taiwan continued to decline until 2010 when the fertility rate was 0,90 children per woman. Population growth is also declining steadily in these countries. Population loss has already started

In the recent years, nonprofit sector has become an important part of modern society and small nonprofit organizations are the major part of nonprofit sector. However, Information Systems (IS) research in the sector has been limited, especially in the context of small nonprofits. In this paper, we attempt to explore the use of IS and IS effectiveness in the small nonprofit context. We also explore

Som ett alternativ till att implementera mjukvaran in-house är det möjligt att hyra mjukvara som en tjänst, detta kallas för Software as a Service (SaaS). SaaS ställer nya krav på leverantör och kund då de ställs inför nya risker och möjligheter. Efter en litteraturgenomgång har vi identifierat dessa och funnit att vissa faktorer betraktas både som en möjlighet och risk. De faktorer som påstås
