Drönare används idag inom en rad områden. Projektet H24LEO, som drivs av Trafikflygarhögskolan vid Lunds Universitet (TFHS) och är finansierat av Vinnova, har som mål att utveckla och demonstrera en drönare driven av ett hybridiserat vätgasbränslecell-system baserat på PEM-tekniken. Denna drönare har som tilltänkt syfte att kunna erbjuda understöd i så kallade Search and Rescure-uppdrag hos SjöfarUnmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce

Bio-based plastics are increasingly considered as sustainable alternatives to fossil-based plastics. Up until now, their application in the food packaging industry has been limited. The purpose of this study is to investigate the applicability of bio-based polymer packaging films for bakery products, herbs and spices in the meal kit industry context and to assess their contribution towards a more

New perspectives on how to best market your brand or products is an ever changing subject. A seemingly unnoticed development in the eyes of ordinary people has been that marketing psychology has become more and more potent in the industry of marketers and brand developers. Benefitting from unconscious behaviors and manipulation has created tools for companies and organizations that this paper is s

We have recently completed the largest GWAS on lung cancer including 29,266 cases and 56,450 controls of European descent. The goal of our study has been to integrate the complete GWAS results with a large-scale expression quantitative trait loci (eQTL) mapping study in human lung tissues (n = 1,038) to identify candidate causal genes for lung cancer. We performed transcriptome-wide association st

Aim: The mechanisms of plant trait adaptation and acclimation are still poorly understood and, consequently, lack a consistent representation in terrestrial biosphere models (TBMs). Despite the increasing availability of geo-referenced trait observations, current databases are still insufficient to cover all vegetation types and environmental conditions. In parallel, the growing number of continuo

Background:Continuous flow peritoneal dialysis (CFPD) is performed using a continuous flux of dialysis fluid via double or dual-lumen PD catheters, allowing a higher dialysate flow rate (DFR) than conventional treatments. While small clinical studies have revealed greatly improved clearances using CFPD, the inability to predict ultrafiltration (UF) may confer a risk of potentially harmful overfill

Objective- RAGE (receptor for advanced glycation end products) and EMMPRIN (extracellular matrix metalloproteinase inducer) are immune receptors for proinflammatory mediators. These receptors can also be found in a soluble form in the circulation. Soluble RAGE (sRAGE) has shown atheroprotective properties in animal studies, possibly by acting as a decoy receptor for its ligands. Whether sEMMPRIN (

The regulation of acetylcholine (ACh) release from cholinergic neurons transplanted to the hippocampus or neocortex was studied by microdialysis in awake rats. Fetal basal forebrain tissue was implanted as a cell suspension or solid graft into the fimbria-fornix-lesioned hippocampus, or as a cell suspension into the frontal cortex after excitotoxic lesion of the nucleus basalis. Several months aft

By being predicated on supervised machine learning, pattern recognition approaches to myoelectric prosthesis control require electromyography (EMG) training data collected concurrently with every detectable motion. Within this framework, calibration protocols for simultaneous control of multifunctional prosthetic hands rapidly become prohibitively long - the number of unique motions grows geometri

ENVRI-FAIR is the connection of the ESFRI Cluster of Environmental Research Infrastructures (ENVRI) to the European Open Science Cloud (EOSC). The high-impact ambition of ENVRI-FAIR is to establish the technical preconditions for the successful implementation of a virtual, federated machine-to-machine interface to access environmental data and services provided by the contributing ENVRIs. This int

Dytiscus latissimus (Coleoptera Dytiscidae) is an endangered diving beetle throughout its range. It is one of the two species of Dytiscidae listed in Annex II of the Habitats Directive, IUCN red list and in many national level legislations and therefore strictly protected. The conservation of endangered species first of all requires an assessment of their population size. Until now, a method has n

Quantitatively identifying the impact of climatic and underlying surface condition changes on runoff is crucial for the efficient utilization of water resources and understanding hydroclimatic variability processes. This study aims to employ both Grid-RCCC-WBM model and Fu's equation based on Budyko hypothesis to quantitatively analyze the spatial patterns of runoff changes, driving forces, and up

OBJECTIVES: Transcutaneous electrical nerve stimulation (TENS) is a noninvasive adjunct to multimodal pain management for acute postoperative care across various surgeries. Despite extensive evidence supporting its efficacy, TENS remains underutilized in clinical practice. This study aimed to assess the knowledge, attitudes, and practices of healthcare professionals regarding TENS in perioperative

Long-term population studies can identify changes in population dynamics over time. However, to realize meaningful conclusions, these studies rely on accurate measurements of individual traits and population characteristics. Here, we evaluate the accuracy of the observational methods used to measure reproductive traits in individually marked black-tailed godwits (Limosa limosa limosa). By comparin

Sedimentary deposits of the Lower Cretaceous Xiagou Formation form the most significant potential hydrocarbon reservoirs in the Qingxi Sag, Jiuquan Basin (NW China). Zircon U-Pb ages of the dated basalts at the top of the Xiagou Formation give an isochron age of 115.6 Ma, and the sedimentation interval of the Xiagou Formation was speculated to range from about 125/124 Ma to 115 Ma based on paleon

The rate of colorectal anastomotic leakage has remained unchanged for the last decades. The limitations of current anastomotic methods have generated an interest in alternative anastomotic techniques, such as compression anastomosis. The aim of this experimental study was to evaluate the early mechanical strength in left colonic anastomoses, comparing C-REX LapAid and circular stapled anastom

Body weight is a predictor of clopidogrel response. However, no prospective studies have compared pharmacodynamic (PD) and pharmacokinetic (PK) data based on body weight. We compared PD and PK effects of clopidogrel 75 mg in low body weight (LBW, <60 kg) and higher body weight (HBW, ≥60 kg) patients with stable coronary artery disease. LBW (n = 34, 56.4 ± 3.7 kg) and HBW (n = 38, 84.7 ± 14.9 kg) a

BackgroundThe relationship between sleeping habits and aortic stiffness remains inconclusive and is not fully explored in the European general population.MethodsWe examined cross-sectionally 8659 participants from the Swedish population-based cohort Swedish CArdioPulmonary bioImage Study (SCAPIS), mean age 57.5 years, 52.1% women. A self-administered questionnaire on sleeping habits (duration, qua

Because Peyer's patches (PP) are the main inductive sites for gut IgA responses we have focused this review on what we know about the function of PP germinal centers (GC).The vast majority of IgA gene sequences in the gut lamina propria (LP) are heavily mutated arguing for an origin in GC. Because PP GC formation is dependent on the presence of CD4 T cells, we speculate that all IgA responses in t

This doctoral thesis aims to investigate and compare conventional drying technologies (freeze-drying and spray drying) to alternative drying technologies for biologics. Vacuum foam-drying was identified as an alternative drying technology for biologics. Vacuum foam-drying is a drying technique that involves solvent removal by evaporation, at lowered pressure and ambient temperatures. Thus, vacuum
