Non-linearity in the energy response of a Si p-i-n charged particle detector has been studied for incident particles with Z(1) between 3 and 26, and energies between 0.1 and 0.7 MeV per nucleon. Although the data closely followed a straight line relations, fitting of the data to a third order polynomial revealed that the response exhibited a persistent curvature that acted to reduce the energy int
This article addresses the short-term decay of advecting-diffusing scalar fields in Stokes flows. The analysis is developed in two main subparts. In the first part, we present an analytic approach for a class of simple flow systems expressed mathematically by the one-dimensional advection-diffusion equation w(y)∂ξ=É∂y2+iV(y)-É′, where ξ is either time or axial coordinate and iV(y) an imaginary pot
Increasing soft error rates for semiconductor devices manufactured in later technologies enforce the usage of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). As RRC introduces time overhead that increases the completion (execution) time, time constraints (deadlines) might be violated. This is a drawback for a class of computer systems where the correct operation is d
BACQUIN, MARI, Theseus de Cologne, édition partielle d’une chanson de geste du XIVe siècle. Études romanes de Lund, 81, 355 pages. Written in French. Monograph. Theseus de Cologne is a French romance from the fourteenth century written by an anonymous author. This voluminous work contains more than 26,000 lines. The text of the romance is preserved in three manuscripts from the fifteenth century,
Rationale: Atherosclerotic plaques that give rise to acute clinical symptoms are typically characterized by degradation of the connective tissue and plaque rupture. Experimental studies have shown that mechanisms to repair vulnerable lesions exist, but the rate of remodeling of human plaque tissue has not been studied. Objective: In the present study, we determined the biological age of different
Roten till cancer? Cancer är en ledande orsak till en stor mängd dödsfall i världen och därför en fruktad sjukdom. Forskningen gör dock framsteg och man kommer allt närmre svaren på gåtorna. På senare år har det föreslagits att en speciell typ av celler, cancerstamceller, är drivande och ligger bakom flera av cancersjukdomarnas egenskaper. Alla organismer är uppbyggda av celler, den stora majoriIn recent years increasing evidence supporting the stem cell hypothesis have emerged and cancer stem cells (CSCs) have been reported to have been isolated in a wide variety of cancers. This CSC population has been attributed to contribute to the therapeutic resistance of many cancers and it is thus of great interest to find new therapeutic options targeting these cells. In ileal carcinoids however
Popular science ArRiyadh, the capital city of the Kingdom of Saudi Arabia is one of the fastest growing cities in the world. During the last decade the population of the city has been increased to five million due to heavy migration towards the city. Due to this population pressure, the living conditions in the different neighborhoods of the city are different. The residents in any city are mainly
Due to globalization, increasing amounts of water are traded across borders as virtual water embodied in traded products. The thesis traces global water trade patterns at different levels of income between 1990 and 2015 in order to test whether developed countries outsource their water-intensive production to less developed countries increasing global water use in the process. The research problem
Sverige är ett av mycket få länder som inte har någon tidsgräns för hur länge häktning får pågå. Dessutom åläggs regelmässigt restriktioner som innebär att den häktade i princip är helt isolerad under häktningstiden. För detta har Sverige fått ta emot långvarig skarp kritik från internationellt håll. Syftet med uppsatsen är att utreda det svenska häktningsinstitutet, med fokus på häktningstidern
Dynamic pricing is a pricing strategy where prices are no longer fixed or constant. Instead, they are continuously readjusted according to perceived demand and factors that influence the desirability of the product. It is in passenger transport where it has one of its biggest applications, in order to increase profits and maximize the use of limited capacity. While extensively studied for its econ
This thesis presents a new way of providing library users with reference services, namely chat (text based digital reference service in real time). Our research questions focus on the role of reference service, a comparison of chat reference to other reference forms, and the interest for real-time, digital reference. Our literature review covered the areas of digital reference and reference theory
OBJECTIVE: to investigate the factors that influence the experience of mothers and fathers when they have chosen to return home, earlier than is the normal routine, following the birth of their baby. DESIGN: a qualitative study, using open interviews, was undertaken. The text of the transcripts was coded and categorised according to the grounded theory method using constant comparative analysis. S
The purpose of this bachelor thesis is to gain a deeper understanding of how Turkey has dealt with freedom of expression. This study analyzes two court cases in which the European Court of Human Rights determined that Turkey failed in its obligation to protect the freedom of expression of two of its citizens, Hrant Dink and Selahattin Demirtaş. The study begins by analyzing the merits of the cases
Adenosine tetraphosphate, or Ap4A, is a nucleotide with very interesting proposed biological effects. Previous studies have indicated that blood glucose levels in mammals might increase in the presence of Ap4A, and that Ap4A might antagonize pancreatic ATP channels. In order to study these effects further, a reliable method of separating Ap4A from other nucleotides in biological samples is require
Background: Musculoskeletal pain is common in the general population and constitutes a major public health problem. A large proportion of these conditions may be work related. The aim of this study was to explore the relative importance of physical, psychosocial and personal factors, in number of pain sites and in five specific pain sites, among women in common professions with a broad variety of
To study the association between induction and outcome among two-parous women in uncomplicated pregnancies ≥ 41+3, stratified by first labour delivery mode and conditions present at first delivery. The Swedish Medical Birth Register was used to identify 58,964 uncomplicated singleton pregnancies among women with one previous birth between 1998 and 2014. Women with any registered pregnancy complica
Many people and organizations across the globe work towards a sustainable future. Artificial intelligence (AI) can be a powerful tool in their efforts.AI technologies, which aim to imitate the natural intelligence of humans and animals, have made enormous progress in the past decade. AI has brought us a whole range of futuristic tools — from self-driving cars to virtual assistants, smart home appl
The aim of this study was to establish traceable number concentration measurements of airborne particles beyond 10 μm in particle size. To this end, the primary standards for particle number concentration at the National Metrology Institutes of Switzerland and Japan were further developed to extend their measurement capabilities. Details on the upgraded setup are provided. An inter-comparison of t
Background: Previous research suggest that autistic children look less at faces than neurotypically developing children, but this finding is based predominantly on screen-based eye tracking studies, with unfamiliar faces used as stimuli. The aim of the current study was to assess 10-month-olds’ gaze to faces in a more naturalistic context - during free play with a parent - in relation to later aut
