Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data

The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. When plants remove carbon dioxide from the atmosphere through the process of phot

Critical levels of atmospheric pollution: criteria and concepts for operational modelling of mercury in forests and lake ecosystems.

Mercury (Hg) is regarded as a major environmental concern in many regions, traditionally because of high concentrations in freshwater fish, and now also because of potential toxic effects on soil microflora. The predominant source of Hg in most watersheds is atmospheric deposition, which has increased 2- to >20-fold over the past centuries. A promising approach for supporting current European effo

STEM-PD trial protocol : a multi-centre, single-arm, first-in-human, dose-escalation trial, investigating the safety and tolerability of intraputamenal transplantation of human embryonic stem cell-derived dopaminergic cells for Parkinson’s disease

Introduction Parkinson’s disease (PD) is a common neurodegenerative disease, which has extensive pathology that critically includes the loss of midbrain dopaminergic neurons. This loss leads to debilitating motor features such as bradykinesia and rigidity, as well as some non-motor symptoms. Intracerebral dopamine cell transplants have been explored for many years as a new approach to treating PD

Ocean Wave Prediction for Arrays of Wave Energy Converters

Short-term wave prediction is a key enabling technology for advanced control of wave energy converters (WECs), where accurate knowledge of the incident wave field over one to a few wave periods can improve power capture, reduce structural loads, and support operational decision-making. Many existing prediction methods rely on measurements at the prediction point or dedicated up-wave sensors, which

Lipid Micro Emboli in Cardiac Surgery

This thesis is based on five studies. It includes the characterization of lipid micro emboli in shed mediastinal blood during cardiac surgery. The reuse of blood directly by cardiotomy suction is a common practice in order to reduce the need of blood transfusions. In shed mediastinal blood we showed that there is an abundance of lipid particles in the size range of 10-60μm. These lipid particles a

Changing Landscapes and Persistent Places : An Exploration of the Bjäre Peninsula

Changing Landscapes and Persistent Places is a study of the cultural landscape on the Bjäre peninsula in northwest Skåne. The many Bronze Age remains that give the landscape its distinctive character are the starting point for an attempt to increase our understanding of the historical depth of today’s landscape. The two perspectives of “landscape” and “places” carry the discussion forward, almost

Investigations of temporal changes in climate and the geomagnetic field via high-resolution radiocarbon dating

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

In-hospital bed occupancy and the emergency department - effects on decisions about the level of care

Popular Abstract in Swedish Bakgrund: Patientflödet genom en akutmottagning regleras framförallt av tre typer av faktorer. Dessa rör i tur och ordning inflödet-, genomflödet- och utflödet av patienter. Faktorer som reglerar inflödet rör efterfrågan på sjukvård (t.ex. samhällsdemografi och tillgång på primärvård), medan faktorer som reglerar genomflödet till största delen rör akutmottagningens inteBackground: Emergency Department (ED) overcrowding occurs when the need for ED services outstrips available resources. Causes have been divided into input, throughput, and output factors, of which the last appear to be the most influential. Unavailability of inpatient beds (so-called “access block,” or “hospital crowding”) impairs ED output and is associated with increased waiting times in the ED

Immunological and Inflammtory Responses against Intrastriatal Neural Grafts in the Rat

Intracerebral neural transplantation offers a new strategy to combat Parkinson’s and Huntington’s diseases. However, a host immune response against a histoincompatible neural graft in the brain may jeopardize transplant survival. We transplanted dissociated mesencephalic tissue prepared from Sprague-Dawley (SD) (syngeneic), Lewis (allogeneic) rats or mice (xenogeneic), into 6-hydroxydopamine (6-OH

Structural pathology and functional analysis of vitamin K-dependent protein S

Protein S deficiency is an autosomal dominant trait affecting around 10% of families thrombophilic families. The high affinity interaction of approximately 60% of protein S with C4b -binding protein (C4BP) has raised a complicated situation for the diagnosis of deficiency states. Because only free protein S functions as cofactor in the protein C anticoagulant, it is important to measure free prote

Geographical variation and systematics of the tetraploid marsh orchid Dactylorhiza majalis subsp sphagnicola (Orchidaceae) and closely related taxa

Dactylorhiza majalis subsp. sphagnicola is an allotetraploid marsh orchid derived from parents closely similar to present-day D. incarnata and the western European form of D. maculata subsp. maculata, suggesting that it has a postglacial origin. It extends from northwestern continental Europe into areas formerly covered by the Weichselian ice sheet in mid-Scandinavia. Here, we studied the variatio

Identifying Drivers and Mechanisms of Climate-Related Tree Mortality

Eastern New South Wales (NSW), Australia, is a region prone to frequent and intense droughts. An unprecedented episode of high temperatures and low rainfall in 2017–2019 culminating in the 2019-2020 summer triggered massive canopy dieback of eucalypt forests throughout the region. Subsequent high rainfall in 2020 offered a unique and rare opportunity to study the process of vegetation recovery fol

Air sampling and biological sampling have been performed to examine the exposure to nicotine in the Nicorette patch and Nicorette gum production at Pfizer Health AB in Helsingborg, Sweden. For this purpose stationary and personal sampling equipment have been used. At the Nicorette patch production, XAD-2 tubes were used to sample nicotine vapor and at the Nicorette gum production Teflon filters we

The influence of land-use change, root abundance and macropores on saturated infiltration rate - a field study on Western Java, Indonesia

The aim of this study was to examine the infiltration rate of water and some parameters affecting it. Especially the land usage, the abundance of roots and macropores were investigated. A field study was carried out on western Java in Indonesia, on the slope of Mount Salak. The study compared four different land uses; i.e. forest, shrub areas, tree plantation and cropland since there was a high o

Late-Glacial and Holocene forest dynamics at Steregoiu in the Gutaiului Mountains, Northwest Romania

Pollen analyses and AMS C-14 measurements were performed on lacustrine sediments and peat deposits from the former crater lake Steregoiu in a mid-altitude area in the Gutaiului Mountains in NW Romania in order to provide a detailed reconstruction of the vegetational development of the area during the Late-Glacial and Holocene. The bottom sediments are siliciclastic and were deposited probably duri

Prevention of intimal hyperplasia after balloon angioplasty and / or stent insertion. or How to mend a broken heart - Just say NO.

Popular Abstract in Swedish Ökat antal patienter som lider av kärlsjukdomar behandlas idag med interventionella metoder istället för kirurgi. Dessa metoder populärt kallade ballong sprängningar, kombineras numera oftast med inläggande av ett metallnät (stent) som hjälper till med att förstärka kärlväggen, så den inte skall falla ihop efter ballong vidgningen. Oavsett vilken metod som används, kompBackground: Restenosis is the most frequently occurring adverse event after percutaneous intravascular treatment of atherosclerotic lesions, which limits long-term patency of the intervention. Objective: The aim of the study was to evaluate if minimizing vascular injury during treatment by insertion of self-expanding stents or modifying the reparative mechanisms by local drug delivery can reduce r

Testing palaeomagnetic and 14C based geochronological methods in the Baltic Sea

Popular Abstract in Swedish Östersjön är ett grundhav med tillförsel av saltvatten från havet och sötvatten från omgivande floder. De två vattenmassorna är vertikalt skiktade, vilket resulterar i en estuarin cirkulation, vilken har genomgått stora förändringar till följd av landhöjningen efter senaste nedisningen. För att kunna rekonstruera havsmiljöers förändringar bakåt i tiden är det nödvändigtThe Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin. For researchers to understand past changes in the marine environment of the Baltic Sea, a soun

A Surface Temperature Initiated Closure (STIC) for surface energy balance fluxes

The use of Penman-Monteith (PM) equation in thermal remote sensing based surface energy balance modeling is not prevalent due to the unavailability of any direct method to integrate thermal data into the PM equation and due to the lack of physical models expressing the surface (or stomatal) and boundary layer conductances (g(S) and g(B)) as a function of surface temperature. Here we demonstrate a
