Denna avhandling behandlar en mängd mikrostrukturella och molekylära lämningar som påträffats i ett antal fossil. Resultaten presenteras i sex vetenskapliga artiklar med det gemensamma syftet att grundligt studera dessa lämningar med hjälp av såväl nya som vedertagna analysmetoder. Avhandlingens huvudsakliga frågeställningar är dels vad denna typ av fossila spår kan säga om de studerade djurens biThis thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods. The main questions asked are: What can we learn about the biology, ecology and

The case Micula gave people the impression that EU law and ICSID arbitration law are incompatible legal orders, unable to accept each other’s dissenting opinions. Every ICSID tribunal decision in the field seems to cause heavy defence reactions in the EU legal system. However, this clearly does not have to be the case if all parties involved behave cautiously. This thesis will analyse in detail

VI Delimitations The company has several product families but only one is investigated in this project. There are today two main warehouses at the production site, the warehouse for raw material and the one for finished goods, where only the latter was studied. There are other places within the company where capital could be tied up as well, e.g. when products are being processed in a machine, but

This study investigates the relationship between the adoption of ‘good’ corporate governance practices and the subsequent stock performance of China’s publicly listed firms. Using the Shanghai Stock Exchange Corporate Governance Index (SSE CGI) that was launched in January 2008, a portfolio of CGI firms is benchmarked against a portfolio of matched conventional firms, their sector indices and mark

Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. Whispering Gallery Mode Resonators have small mode volumes and strong beam confinement leading to high Quali

A transcription of the first episode of season three. Nic: We are back! You are listening to the first episode of a brand new third season of the Meridian and we are once again coming to you from Lund Observatory in southern Sweden.   We are starting strong this season. A few weeks back, NASA astronaut Jim Pawelczyk, who is an associate professor of Physiology, kinesiology and medicine, visited Lu

Drawing on unique sources from the Swedish Migration Agency Archive, this article examines how Afghan asylum seekers and refugees fared in their encounter with Swedish internal and external controls of people seeking protection from persecution during the Cold War. Within a theoretical framework that draws on the concept of statist logic, the history of refugeehood, interactionist sociology and cr

The purpose of this thesis was to investigate the difference between Pre-emptive and the Preventive use of force in a low-intensity conflict to which the drone campaign is a critical part of. Northern Pakistan has borne the brunt of the U.S. led drone campaign, and the Obama administration has exponentially increased the number of strikes that continues to target armed non-state entities in the tr

In February 2002, the UNITA rebel leader Jonas Savimbi was shot dead by Angolan Government forces, thereby putting an end to almost four decades of war in Angola. Once peace had been declared, the Government of Zambia together with the Government of Angola and the UNHCR began to make arrangements for the voluntary repatriation of the large Angolan refugee population residing in Zambia. However, du

With standard and resonant x-ray magnetic diffraction we investigate the magnetic properties of Pt atoms in a Co/Pt(111) system. It is shown, that, depending on the thickness of the Co films, the magnetic anisotropy as monitored by the Pt magnetism changes from perpendicular to parallel, mimicking the behavior of the Co overlayer. Adsorption of carbon monoxide on very thin films has been found to

It has been shown that long-range p-wave superconductivity in a Kitaev chain can be engineered via an ac field with a high frequency [M. Benito, Phys. Rev. B 90, 205127 (2014)PRBMDO1098-012110.1103/PhysRevB.90.205127]. For its experimental realization, however, theoretical understanding of Floquet engineering with a broader range of driving frequencies becomes important. In this paper, focusing on

Background and Purpose: Absence from work due to illness is common in many western countries and has many negative consequences for both the individual and society. Since 2020 Swedish healthcare regions are required to provide resources to coordinate the rehabilitation process, a complex system involving medical as well as work-related parties, where both the physician and the rehabilitation coord

How do early-life conditions affect adult mortality? Research has yielded mixed evidence about the influence of infant and child mortality in birth cohorts on adult health and mortality. Studies rarely consider the specific role of mortality within the family. We estimated how individuals’ exposure to mortality as a child is related to their adult mortality risk between ages 18 and 85 in two histo

Diluting the combustion mixtures is one of the advanced approaches to reduce the NOx emission of methane/air premixed turbulent flame, especially with high diluents to create a distributed reaction zone and mild combustion, which can lower the temperature of reaction zone and reduce the formation of NOx. The effect of N2/CO2 dilution on the combustion characteristics of methane/air premixed turbul

This thesis introduces two new incommensurate alloys. AuIn shows variable amounts of modulation, depending on the measurement temperature. At 400°C the diffraction pattern shows diffuse scattering and a thallium iodide type Cmcm space group. The diffuse scattering condenses into first order satellites on cooling to 300°C and the space group transforms to the incommensurate C-1(α, β, γ)0. I.e. the

The analysis of iron, manganese and antimony in silicate glass is of great interest in chemistry, materials science, earth sciences and archaeological sciences. Yet, conclusions from different fields appear to be contradictory and many questions about redox reactions in glass remain. The purpose of this study is thus to discuss whether and how these multivalent elements interact in glass. Soda-lim
