We apply a novel analytical framework based on medium resolution satellite data for the period 2001 – 2012 to estimate the effects of gold mining on agricultural production in Ghana, Mali, Tanzania and Burkina Faso. Our analysis finds a strong correlation between official statistics of agricultural production and vegetation index from satellite data at district level in these cou
Varved lake sediments offer valuable insight into past environmental conditions with high temporal resolution and precise chronological control. A combination of diatom and geochemical analyses of the recently deposited sediments of Odensjön, a small dimictic lake in southern Sweden, shows alternating light and dark laminae composed of greater amounts of biogenic silica and organic matter, respect
Someone who throws away their rubbish on a street-corner or in a ditch is guilty of sloth. This may appear harmless, but seen through the lens of waste management, sloth soon develops into a deadly sin that harms other people’s lives and health. Hiding and forgetting waste has always been a practice with potentially disastrous consequences; buried containers full of toxins will eventually start to
Biologically active vitamin B6-derivative pyridoxal 5′-phosphate (PLP) is an essential cofactor in amino acid metabolic pathways. PLP-dependent enzymes catalyze a multitude of chemical reactions but, how reaction diversity of PLP-dependent enzymes is achieved is still not well understood. Such comprehension requires atomic-level structural studies of PLP-dependent enzymes. Neutron diffraction affo
Naturally occurring plant cellulose, our most abundant renewable resource, consists of fibers of long polymer chains that are tightly packed in parallel arrays in either of two crystal phases collectively referred to as cellulose I. During mercerization, a process that involves treatment with sodium hydroxide, cellulose goes through a conversion to another crystal form called cellulose II, within
OBJECTIVE: To explore the quality of maternal and newborn care (QMNC) during the COVID-19 pandemic by facility type among 16 European countries, comparing rates of instrumental vaginal birth and cesarean.METHODS: Women who gave birth in the WHO European Region from March 1, 2020, to February 7, 2022, answered a validated online questionnaire. Rates of instrumental birth, instrumental vaginal birth
Heart failure (HF) is a leading cause of death and disability globally. HF represents the common end- stage of most heart conditions, during which the heart is unable to generate sufficient output of blood for the metabolic demands of the body and intracardiac pressures increase. Different heart diseases display specific molecular pathophysiologies, but common pathways are also present that drive
BACKGROUND: In the European Union alone, more than 100 million people present to the emergency department (ED) each year, and this has increased steadily year-on-year by 2-3%. Better patient management decisions have the potential to reduce ED crowding, the number of diagnostic tests, the use of inpatient beds, and healthcare costs.METHODS: We have established the Skåne Emergency Medicine (SEM) co
Data on marine microfossil assemblage composition have multiple applications. Initially, they were primarily used for (chrono)stratigraphy and palaeoecology, but these data are now also widely used to study evolutionary and ecological processes, such as past biodiversity and its links with environmental dynamics, or to provide a basis for conservation efforts and biomonitoring. The large range of
Hypothesis: Sponge phase (L3) lipid nanoparticles (L3-NPs) have been shown to have large potential for the encapsulation of biomolecules, such as enzymes, with applications in food and pharmaceutical science. In this study, we introduce new formulations of L3-NPs including the phospholipids dioleoylphosphatidylcholine (DOPC) and dioleoyltrimethylammonium propane (DOTAP). The interaction of these n
Freshwater ecosystems in boreal and temperate regions are undergoing rapid change as increasinginputs of terrestrially derived dissolved organic matter (DOM) and nutrient enrichment alter ecosystemfunctioning. These processes, known as brownification and eutrophication, vary across space and timebut can profoundly reshape carbon cycling, microbial activity, and water quality. This thesis investiga
The one-particle Green function of a many-electron system is traditionally formulated within the self-energy picture. A different formalism was recently proposed, in which the self-energy is replaced by a dynamical exchange-correlation field, which acts on the Green function locally in both space and time. It was found that there exists a fundamental quantity, referred to as the dynamical exchange
Aerosols can influence vegetation through multiple processes, yet the resulting biophysical climate feedback from the vegetation response remains poorly understood. Here, using an ensemble of Earth system models and an observation-based empirical model, we show that the vegetation response to complete removal of anthropogenic aerosols can either cool or warm the local climate by up to 0.039 ± 0.02
The book is a summary of excursion guides for the Lund University course NGEA 04 “Ecosystem analysis”—a field course week held on Öland 2000 to 2025. The guide serves as an introduction and overview of basic information about certain physical geographical environments, features, and general physiographic and ecological traits of southern Öland. Primarily, it offers a general introduction to the is
Urbanization is driving cities to grow, often through urban densification. Utilising computer-based simulations executed over 3D representations of the city is imperative in addressing the challenges posed by implementing sustainable urban densifications; like ensuring adequate access to daylight and limiting noise pollution. However, since these simulations are usually resource-intensive, timecon
Hybrid energy systems have become a promising strategy for enhancing power utilization efficiency while preserving ecology. Previous research has predominantly focused on developing models with fixed ecological constraints. However, the fixed ecological constraints overlook dynamic ecological uncertainty and its interaction with operation decisions. This study proposes adaptive operating rules for
