The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow upsilon(2)(eta)), as determined recently by the PHOBOS experiment for Au + Au collisions at root(S)NN = 130 and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of upsi
The apposition compound eye of a nocturnal bee, the halictid Megalopta genalis, is described for the first time. Compared to the compound eye of the worker honeybee Apis mellifera and the diurnal halictid bee Lasioglossum leucozonium, the eye of M. genalis shows specific retinal and optical adaptations for vision in dim light. The major anatomical adaptations within the eye of the nocturnal bee ar
Low B fractures and prevalent vertebral fractures are known risk factors for incident vertebral fractures. In 3001 men and women from the Rotterdam Study, prevalent nonvertebral fractures early for incident menopause, current smoking, and walking aid use were also strong risk factors for incident vertebral fractures.
We report the development of a high-level bacterial expression system for the Alzheimer's disease-associated amyloid beta-peptide (A beta), together with a scaleable and inexpensive purification procedure. A beta(1-40) and A beta(1-42) coding sequences together with added ATG codons were cloned directly into a Pet vector to facilitate production of Met-A beta(1-40) and Met-A beta(1-42), referred t
Objective. Primary aldosteronism (PA) is the most common form of secondary hypertension. Thus, the aims of this study were: (1) to clarify whether the fludrocortisone suppression test (FST), which confirms autonomous aldosterone secretion, is reliable when carried out during a shorter period of time and (2) to confirm the importance of NaCl supplementation. The cut-off limits already obtained for
Weak separability is an important concept in many fields of economic theory. This chapter uses Monte Carlo experiments to investigate the performance of newly developed nonparametric revealed preference tests for weak separability. A main finding is that the bias of the sequentially implemented test for weak separability proposed by Fleissig and Whitney (2003) is low. The theoretically unbiased Sw
Since their emergence in the 1950’s, ice cores have ventured from being scientific objects of concern to a limited number of glaciologists to becoming one of the most iconic representations of anthropogenic climate change. This thesis aims to historicize the way in which ice cores became enrolled into climate discourse, particularly emphasizing the production and representation of temporalities of
Inflammation and subsequent endothelial dysfunction are main players in the vascular component of hypertension, and recent findings points to a key role of Sphingosine- 1-Phosphate and its signaling pathways in its pathophysiology. In neurodegenerative disorders such as Alzheimer’s disease, hypertension is the main modifiable risk factor, but insights regarding S1P receptor modulation in response
This Master Thesis aims to show an approach to the design of parallel robots,specifically the development of its kinematics. To do this, screw theory will be used, focusing on its theoretical bases and taking it later to practice. First, a theoretical definition of the inverse and forward kinematics of a parallel robot is carried out. Subsequently, algorithms are generated in Python that verify t
In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled. Examples of variables are heat release, ventilation mode and factors within evacuation modelling
Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. In this report, the possibilities of
Presentation of problem: The movement of sediment parallel to the coast by waves and currents is known as longshore sediment transport or littoral transport. Throughout the years, researchers have found that knowledge of longshore sediment transport is important in connection with coastal engineering design, such as construction of breakwaters at harbour entrances, dredging of navigation channels,
The present study investigated the effects of three factors on the level of realism in frequency judgements. These factors were: Instruction (No correction for guessing/Correction for guessing), Format (whether the frequency judgements were made in terms of absolute numbers or in percent) and Difficulty level (easy/hard set of questions). All three factors were found to have a significant effect o
The present research is aimed at analyzing spirituality according to the way it is presented in academic management literature. To uncover comprehensively way this phenomenon is described, a thorough scientific analysis of the selected articles was performed including coding the materials, systematically categorizing them as well as critically investigating particular aspects. While conducting the
I en allt mer globaliserad värld och efter den digitala revolutionen, har skyddet för personuppgifter hamnat i rampljuset. Numera, utbyts data över nätet dagligen för olika syften, såsom privata, kommersiella och allmänna, vilket har skapat en oro för hur dessa överföringar av personuppgifter kan påverka rätten till dataskydd och rätten till privatliv. Inom EU har det funnits en tradition av att In an increasingly globalized world and after a decade of digital revolution, the protection of personal data has fallen in the limelight. Nowadays, data is exchanged over the internet daily for various purposes, including strictly private, commercial, as well as public, which has raised concerns on how these transfers of personal data may affect the right to data protection and the right to priva
Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. By implementing a treatment planning system for FLASH-irradiation, the dose distribution can be visualized and the gantr
The goal of this article is to propose, through the use of GIS software, an interdisciplinary method to suggest new touristic flows after the Covid-19 pandemic. Specifically, the aim is to identify those sites of cultural and landscape interest that are little known but with great artistic, cultural, historical and environmental value that could give new vigour to the tourism sector. In the first
Myths, religious beliefs, and symbols are crucial components of ethnicity. PKK as a nationalist separatist armed organization- intensively uses them to construct a Kurdish identity which is compatible with its ideology as well as its objectives to mobilize Kurds and to galvanize their support. This thesis seeks to describe how PKK –as a militant organization- has instrumentalised Islamic related t
