Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. The North Sea is an important fishing ground, and any changes in phytoplankton bloom patterns can have a significant impact on the region'
Galaxies with high redshift (z) are galaxies in the early universe, and they differ from local ones. They often show more irregular morphologies and significantly different kinematic properties, as turbulent motion dominates. These early galaxies have higher gas velocity dispersion (σ) and lower rotation-to-dispersion (vrot/σ) values. Recent findings from both the JWST and the Atacama Large Millim
The overall aim of this work is to study and interpret how social relations were expressed, shaped, and changed in the Late Middle Neolithic. The empirical foundation is a study of settlement in the Malmö area, south-west Skåne, Sweden. Other parts of southernmost Sweden (and eastern Denmark) are also concerned. Sites are discussed and given an overall interpretation as regards chronological and c
PURPOSE: To examine the effects of focal laser photocoagulation on general and local retinal function and to relate electrophysiological findings with changes in protein kinase C (PKC) alpha expression. METHODS: Twelve rabbits were treated with 70 spots of laser photocoagulation in the central cone-rich retina. The operated eyes were investigated with electroretinography (full-field ERG and multif
The exocrine pancreas is mainly regulated via neuro-hormonal pathways. CCK-dependent regulatory pathways and CCK-receptor subtype involved seem to differ between mammalian species. The first aim of the thesis was to establish the physiological dose-range for CCK, to further explore the short entero-pancreatic reflex and CCK-receptor subtypes involved in the CCK-mediated regulation of the exocrin
In analyses of affordances and opportunities in different neighbourhoods it is found that access to public buildings and a well-functioning public space are of outmost importance. This is found to be especially important in neighbourhoods having a population with fewer resources, areas often discussed in terms as ‘deprived’ or ‘excluded’, concepts that alludes to the phenomenon of segregation. Pre
A pollen record obtained from a 2.2-m sediment succession deposited in a small lake in the province of Vasterbotten, north-eastern Sweden, reveals the presence of continuous forest cover since 8,500 calendar years before present (cal B.P.). Forest with abundant Pinus (pine) and Betula (birch) initially colonized the area, followed by a dominance of deciduous trees, primarily Betula, from ca. 8,000
Self-organization and pattern formation represent the emergence of order in temporal and spatial processes. Self-organization in population ecology is gaining attention due to the recent advances concerning temporal fluctuations in the population size of dispersal-linked subunits. We shall report that spatially structured models of population renewal promote the emergence of a complex power law or
Illegal timber harvest and trade is one of the main challenges in the context of global deforestation and sustainability. Different governance and self-governance initiatives throughout the history with the aim to regulate global forest commons have received plenty of criticism. This research investigates the potential of genetic timber tracking technologies as a tool to enhance existing systems a
Agricultural management and vegetation complexity affect arthropod diversity and may alter trophic interactions between predators and their prey. Web-building spiders are abundant generalist predators and important natural enemies of pests. We analyzed how management intensity (tillage, cutting of the vegetation, grazing by cattle, and synthetic and organic inputs) and vegetation complexity (plant
Acute Pancreatitis (AP) is an inflammation disease that characterized by activation of protease and the innate immune system, leading to infiltration of neutrophils and tissue damage in the pancreas. The aim of this thesis was to determine the role of isoprenylation (farnesyltransferase and geranylgeranyltransferase) as well as NET formation in regulating recruitment of neutrophils and tissue dama
Ett nytänk behövs för våra cykelvägar! Våra växande städer är helt uppbyggda kring transporter med bil. För att kunna bromsa klimatförändringarna behöver vi tänka nytt. Färre bilar och fler cyklar är en av lösningarna som förts fram allt oftare på senare år. Köpenhamn och Amsterdam är de städer som nått längst i att få människor att cykla i stället för att ta bilen. Ju vanligare cyklar blir i trafIn several other European countries, the number of electric bikes (pedelecs) has increased significantly in recent years. A similar increase is also expected in Sweden. So far the knowledge of the attitudes of people using electric bikes in Sweden are limited. This study consists of interviews with 39 persons from all around Sweden to get a better understanding of why they have chosen to ride an e
In an influential paper, Hansen (Rethinking the Univariate Approach to Unit Root Testing: Using Covariates to Increase Power, Econometric Theory 11, 1148–1171, 1995) shows that covariate augmentation can lead to substantial power gains when compared to univariate tests. In this paper we ask if this result extends also to the panel data context? The answer turns out to be yes, which is maybe not th
Unprecedented global challenges demand wide-reaching societal modification to ensure life support functions and human well-being. In the absence of adequate international responses to climate change and the need for place-based adaptation, local governments have a pivotal role in fostering sustainability transitions. In this context, the importance of ecosystem-based adaptation is increasingly rec
Objective. We evaluated in a proof-of-concept double-blind placebo-controlled randomized trial the efficacy and safety of intra-articular sprifermin (recombinant human fibroblast growth factor 18) in patients with symptomatic knee OA. Methods. Sprifermin was evaluated as intra-articular injection at 10, 30, and 100μg. Primary efficacy endpoint was change in central medial femorotibial compartment
Background: Emerging data propose biomarker alteration due to clonal selection between the primary invasive breast cancer and corresponding metastases. In addition, impact on survival has been demonstrated. The present study investigates the relationship between the oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) between primary ductal carcin
This paper looks at trust as an object of historical analysis in micro-credit exchanges at the village level before the advent of capitalism. Based on the examination of loans recorded by the notary over the course of the eighteenth century, this paper seeks to shed light not only on the mechanisms of norms of cooperation and trust but also, and more importantly, on the paradigm of trust over time
Purpose: To study the impact of dose fractionation of adjuvant radiation therapy (RT) on local recurrence (LR) and the relation of LR to radiation fields. Methods and Materials: LR rates were analyzed in 462 adult patients with soft tissue sarcoma who underwent surgical excision and adjuvant RT at five Scandinavian sarcoma centers from 1998 to 2009. Medical records were reviewed for dose fractiona
Historically , the fire safety code systems now in force had to be written without actually stating their objective level of safety and, still far less , without any analytical measurement of the objectives involved. For this reason, there is an urgent need for future attempts to evaluate the levels of safety inherent in present local and national fire protection regulations. Lack of knowledge wit
Capsaicin is used to investigate the role of peripheral sensory nerve fibers. In previous studies of rats treated by injection of capsaicin into the skin of the neck, 'spontaneous' lesions in the head and neck region were observed. In this study, the course of development over time, the regional distribution and the innervation of capsaicin-induced dermal lesions were assessed in young male Spragu
