Hur låter musiken som spelas av atomer? Även om de inte kan sjunga så kan atomer – de små byggstenarna som bygger världen – interagera starkt med laserljus och då skapa kortvariga ljusblixtar som är lika harmoniska som musik. Att förstå hur laserljus och ljusblixtar är relaterade är genom deras interaktioner med atomer. Detta kommer att hjälpa oss att följa aktiviteten som händer så snabbt att denLight-matter interactions can be used to probe both light and matter as they yield information on a system's state. On the ultrafast timescale, it is possible to employ these interactions to probe fast-occurring phenomena. In particular, one of the few tools for ultrafast spectroscopy are coherent attosecond XUV pulses: light pulses in the extreme ultraviolet range (XUV) whose typical duration

In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), …, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estim

Det faktum att våld i nära relationer oftast utspelar sig inom hemmets fyra väggar gör att det följer svårigheter. Bristen på vittnen gör det besvärligt att få gärningsmannen lagförd. I en tredjedel av alla fall med våld mot kvinnor i hemmet bevittnar dock barn brottet. Trots detta förhörs barn som vittne endast i 18 % av dessa fall. Förundersökningen läggs ofta ner eftersom tillräckliga bevis intThe fact that violence in intimate relationships most often takes place in someone’s home, makes it difficult to prosecute the perpetrator in lack of witnesses. In one third of the cases regarding violence against women in intimate relationships, children are witnesses. Despite this, children are interrogated only in 18 % of these cases. The preliminary investigation is often closed because of the

Multinational Corporations (MNCs) or Multinational Enterprises (MNEs) are of great importance in the global economy. A great amount of international trade is either between multinational corporations or within a multinational corporation, which is called intra-firm trade. Therefore, intra-firm trade is also of importance in the global economy. The price used in intra-firm trade is called transfer

In order to better understand impact of extreme weather events on condition of crop vegetation in Ukraine, analysis of agricultural droughts which occurred in the southern region of Ukraine, between years 2000-2012 was conducted in the current research. Method of the research In the current research, the impact of droughts was analyzed on yearly basis by assessing vegetation conditions and compar

Background: The use of functional genomics has largely increased our understanding of cell biology and promises to help the development of systems biology needed to understand the complex order of events that regulates cellular differentiation in vivo. One model system clearly dependent on the integration of extra and intra cellular signals is the development of B-lymphocytes from hematopoietic st

This dissertation explores how son preference is constructed and renegotiated in light of social change in the People’s Republic of China (PRC). Based on secondary sources and interviews with women and men in rural Anhui Province as well as key informants, it addresses son preference from conceptual, methodological, empirical and ideological perspectives. The analysis centres around son preference

It is clear that media advertising is one of the crucial marketing tools for companies in order to promote their products and services. As we are moving towards more and more economic integration, both on a regional and global scale, the question about standardisation of media advertising has become increasingly important and is nowadays subject to discussion in most international companies. This

Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater tre

Popular Abstract in Swedish Ljusspridning och absorption i biologisk vävnad - modeller och mätningar Visionerna är stora i medicingruppen på avdelningen för atomfysik, LTH, nämligen att utveckla nya metoder för förfinad diagnostik och selektiv behandling av cancer, hjärt- och kärlsjukdomar med hjälp av laserljus. Möjligheten till att med ljus detektera och karakterisera sjuk vävnad, exempelvis tIn this work a number of theoretical models, describing light propagation in matter, have been applied to and developed for the examination of tissue. The aim was to model the light scattering and absorption in tissue in order to improve the understanding of underlying mechanisms of laser-based diagnostics and treatment modalities utilised for cancer and cardiovascular diseases. The models studied

Popular Abstract in Swedish Vid Typ 1 diabetes mellitus (insulinberoende, [ungdoms]) förlorar kroppen förmågan att tillverka insulin, det hormon som styr upptaget av socker i kroppens celler. Insulinet bildas av bukspottskörtelns hormonproducerande betaceller, och Typ 1 diabetes orsakas av att dessa celler skadas och förstörs. Denna skadeprocess anses idag i de flesta fall förmedlas av kroppens egAutoantibodies against glutamic acid decarboxylase (GADA), protein tyrosine-phosphatase-like protein (IAÐ2A), and/or pancreatic islet cells (ICA) are autoimmune markers usually present at diagnosis of Type 1 diabetes. Type 1 diabetes is therefore in general believed to be caused by an immune-mediated beta cell destruction. In children this destruction is fast, whereas in adult patients Type 1 diab

Objective To derive simple and clinically useful ultrasound-based rules for discriminating between benign and malignant adnexal masses. Methods In a multicenter study involving nine centers consecutive patients with persistent adnexal tumors underwent transvaginal gray-scale and Doppler ultrasound examination using a standardized examination technique and standardized terms and definitions. Inform

Background Hazardous drinking has been associated with an increased postoperative complication rate after surgery. Common complications include postoperative infections, cardiopulmonary complications, and bleeding episodes. Preoperative abstinence may to some degree reverse alcohol-induced pathophysiological processes and thus prevent postoperative complications. Objectives To assess the effect of

Background Despite high incidence of ankle fractures in the elderly, studies evaluating outcome and impact of quality of life in this age group specifically are sparse. The aim of this study was to evaluate outcome and quality of life 6 and 12 months after injury in patients 65 years or older who had been operated on due to an ankle fracture. Methods Sixty patients 65 years or older were invited

During the early 1990s, a novel style of programming often referred to as component-oriented programming quickly grew popular as the state-of-the-art in graphical user interface and client/server development on Windows-based personal computers, largely in competition with object-oriented programming, a partly similar, partly different programming paradigm, with which component-orientation is often

The scheme of concepts we employ in daily life to explain intentional behaviour form a belief-desire model (BD model), in which motivating states are sorted into two suitably broad categories. The BD model embeds a philosophy of action, i.e. a set of assumptions about the ontology of motivation with subsequent restrictions on psychologising and norms of practical reason. A comprehensive critique o
