Klimatet har varit relativt stabilt under den nuvarande interglaciala epoken (Holocen) som inleddes för ungefär 11 700 år sedan. Genom klimatrekonstruktioner från olika geologiska arkiv såsom iskärnor, sjösediment och torvmossar har det ändå påvisats att snabba förändringar i klimatet har inträffat under denna epok. En sådan tidsperiod inträffade för omkring 2800 år sedan och den är intressant ur Geological archives have shown periods of abrupt climate change in the relatively stable Holocene epoch (last ca. 11 700 years). One of these periods was around 2800 cal BP. Several records, mainly from Europe, reveal a shift towards wetter, cooler and windier conditions. There are, however, indications for a global extent of the climate change. The climate change coincides with a distinct increas

The Swedish Antarctic Research Expedition named “SWEDARP” was performed during October 1988 through April 1989. The aim of our project was to study the radioactivity in air and water from Gothenburg to the Antarctic. Between Gothenburg and the Equator, the average activity concentration of 7Be in air was 4.3 ± 0.7 mBq/m3. The activity concentration of 7Be in the South Atlantic down to Antarctica v

The use of acoustic forces to manipulate particles or cells at the microfluidic scale (i.e. acoustophoresis), enables non-contact, label-free separation based on intrinsic cell properties such as size, density and compressibility. Acoustophoresis holds great promise as a cell separation technique in several research and clinical areas. However, it has been suggested that the force acting upon cell

Popular Abstract in Swedish Förståelse av hjärtats pumpförmåga är av yttersta vikt för att kunna behandla patienter med hjärtsjukdom, framförallt hjärtsvikt. Studier av hjärtat har av naturliga skäl framförallt gjorts med öppen bröstkorg eller med hjärtat uttaget ur kroppen, och detta påverkar hjärtats pumpning. Magnetresonans-kameran gör det möjligt att avbilda hjärtat i alla delar av hjärtcykelnCardiac pumping physiology is important for understanding the pathophysiology of patients with cardiac disease. MRI gives the opportunity to measure volumes and flow non-invasively with high accuracy and precision. This thesis examines some aspects on cardiac pumping physiology. Study I showed that the total heart volume in humans decreases during systole by ~8 % (range 5-11 %), and anatomically i

AimsWe recently identified a metabolic signature of three amino acids (tyrosine, phenylalanine, and isoleucine) that strongly predicts diabetes development. As novel modifiable targets for intervention are needed to meet the expected increase of cardiovascular disease (CVD) caused by the diabetes epidemic, we investigated whether this diabetes-predictive amino acid score (DM-AA score) predicts dev

BACKGROUND. Understanding the genetic architecture of cardiac structure and function may help to prevent and treat heart disease. This investigation sought to identify common genetic variations associated with inter-individual variability in cardiac structure and function. METHODS. A GWAS meta-analysis of echocardiographic traits was performed, including 46,533 individuals from 30 studies (EchoGen

Effective communication between students and supervisors has been shown to be of importance for a high quality doctoral education by many pedagogical studies (Manathunga [1], Delamont, Aktinson and Parry [2], Halse and Malfroy [3], Bergnéher [4]). This contribution focuses on communication between supervisors and doctoral students with regard to the writing of the doctoral thesis. When it comes to

Objectives: . SLE is an autoimmune disease with increased cardiovascular morbidity and platelet activation. In the general population, increased platelet size predicts platelet reactivity and cardiovascular disease. The aim of this study was to investigate whether platelet size related to platelet activation and cardiovascular disease in SLE.Methods: . Fresh blood samples from SLE patients ( n = 1

Background and purpose - Little is know about patterns of sick leave in connection with total hip and knee joint replacement (THR and TKR) in patients with osteoarthritis (OA). Patients and methods - Using registers from southern Sweden, we identified hip and knee OA patients aged 40-59 years who had a THR or TKR in the period 2004-2012. Patients who died or started on disability pension were excl

The intricate balance between dopaminergic and cholinergic neurotransmission in the striatum has been thoroughly difficult to characterize. It was initially described as a seesaw with a competing function of dopamine versus acetylcholine. Recent technical advances however, have brought this view into question suggesting that the two systems work rather in concert with the cholinergic interneurons

Rhetoric is a teaching tradition. The rhetorical exercises in the progymnasmata are the main method in which rhetoric has been taught throughout history. These exercises are organized according to difficulty, the material covered, the rhetorical genre, the canons of rhetoric and the disposition of the speech. The main organizing principle is however the topoi for inventing the speech or text in ea

This thesis is a phenomenological investigation into the differences and similarities between language as speech and language as a technique. Speech is the practice of producing and understanding utterances. A technique is the organizing mechanism of speech, the structure that gives it a regular form. While speech is heavily dependent on context and interpretation, a technique is unaffected by theThis thesis is a phenomenological investigation into the differences and similarities between language as speech and language as a technique.

In an effort to improve our understanding of the etiology and treatment of disorders involving symptoms of anxiety and depression, researchers have set out to identify psychological traits that may leave an individual vulnerable to experiencing intense negative emotional reactions. Included among these vulnerabilities are a person’s ability to tolerate negative emotional states (Distress Tolerance

Title: ABILITY > KNOWLEDGE - Can Learning Organizational Qualities be trained in the school system through Supplemental Instruction, and if so, how early? Issue of Thesis: The acceleration of the amount of knowledge that an organization in the 21st century needs to process is growing with exponential numbers. In order to survive, the organizations need to transform themselves into Learning Organi
