The present thesis constitutes a close study of a single architectural monument, the tomb of Caecilia Metella. This is a well-preserved cylindrical tomb situated on the Via Appia outside Rome, and it is generally associated with sepulchral buildings of the traditional tumulus type. An inscription reveals that the occupant of the grave was a noble woman belonging to one of the most prestigious fami

Vi dyker tillsammans ner i tropiska hav och observerar tusentals färgglada fiskar simma förbi oss. Vi reser runt Jorden och undersöker olika typer av korallrev och de djur som där bor. Vi lär oss hur forskare tar fram nya metoder för att skydda och hjälpa Korallrevens Värld överleva nu när havstemperaturen stiger.Under vår resa upptäcker vi hur koraller lever, andas samt hur de förökar sig. KorDive into a tropical ocean and see thousands of colorful fish flutter by. Travel the globe to explore coral reefs teeming with life and learn how scientists are racing to develop sustainable solutions to protect these vitally important ecosystems for the future. Along the way, discover how corals live, breathe, and reproduce, supporting a quarter of all marine life on Earth and providing critical

This thesis deals with radio wave propagation in environments where the propagation is severely influenced by surrounding objects, mainly walls and other building structures. As an introduction, a brief description is given on propagation terms like loss, delay and dispersion along with system functions relevant for the topic. The focus is then placed on propagation from an outdoor transmitter to

The thesis is a reception study and the focus of the research is on what happens during the reading process when an upper secondary school class reads fiction. The theoretical basis consists of theories of reading as transaction and the envisionment-building and dialogic classroom. A process-based and relational perspective on reading, writing and oral exchange in teaching has been central. The e

This doctoral dissertation presents a study of linear radio transmitters based on the combined analog locked loop universal modulator (CALLUM) approach. Linear architectures such as CALLUM are very attractive for power-efficient operations, since they have no fundamental limitations prohibiting a 100% efficiency for all envelope levels, without sacrificing the potential of a linear transmission. T

Trädgårdsgatan is a warm and heartfelt depiction of a divided Helsingborg and Sweden in transition. The play depicts three generations of women and their arduous efforts to deal with every-day life with work, marriage and children in the 1970s, 2000s and 2020s. Almost 50 years separate them, but they are united in their longing for a simpler and better life.At the centre of the story is Birgitta,

The aim of the thesis is to contribute to knowledge about experience and perceptions of reading that students at a school of education have, from early reading experiences in childhood, to the encounter with reading in context of their teacher training. The following overarching questions were asked: What aspects of narratives appear to be significant in the students’ reading trajectories? Which a

The thesis investigates the theoretical background and the research context within which interpretations of the Nordic Bronze Age have been formed in Scandinavian archaeology. A theoretical analysis that emphasises theories of social practice and phenomenological perspectives is presented. The purpose of the analysis is to explore theories of social practice as tools for grasping the dynamic relat

The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. The impact of changes

It is difficult for states to cooperate on issues related to international peace and security. Yet, ever since 1970, the EU member states have succeeded to gradually intensify their foreign policy cooperation and increasingly act in unison towards the rest of the world. This PhD thesis seeks an explanation to this trend. It does so by initially painting a picture of when, in time, the volume and c

The drying of a porous material occurs in two different periods: the constant rate period and the falling rate period. During the constant rate period, the drying rate is determined by the external conditions regarding heat and mass transfer, and the drying rate is not influenced by the properties of the drying material. During the falling rate period, the material properties, such as the transpor

The aim of the study is to improve on the understanding of the implications for adolescents of being placed in foster care. The basis for the study is that the adolescents´ previous relationship with their parents has significance for the manner in which the adolescents will handle the separation from the parents and how they will relate to foster parents. 27 adolescents aged 13-16 years were exam

This book presents a study on general and specific problems concerning the role, functions and structure of criminal justice systems. After a presentation of some ideological and methodological issues, the justifications for different principles of criminal jurisdiction are discussed, both in the perspective of public international law and municipal law. The constituent elements of criminal offenc

The aim of this study was to expand our understanding of the processes of institutionalisation both within and between organisational fields. This was done by tracing an idea – the idea of quality assurance – through the process of institutionalisation in the health care sector. The new institutional theory, which focuses on the relation between organisations and the institutions they are consider

Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. After release into the atmosphere, the particles are subjected to complex dilution and transformation processes that are of

This thesis treats the problem of transient electromagnetic pulse propagation in temporally dispersive media. The analysis is performed using time-domain techniques. In particular, the dispersive wave splitting which decouples the Maxwell equations both in vacuum and inside the medium is utilized. Complex time-dependent electromagnetic fields are introduced. These fields simplify the Maxwell equat
