A method for respiratory rate estimation from electrocardiogram (ECG), based on variations in QRS complexes slopes, is evaluated over stress testing recordings. Besides the 12 standard, and the 3 vectorcardiogram (VCG), 2 additional leads derived from the VCG are analyzed. A total of 34 slope series were studied, 2 for each lead: slopes between the peaks of the Q and R waves, and between the peaks
Industrial symbiosis can move us closer to a circular economy and enable efficient and sustainable use of resources. Its potential has however been far from realized, and to increase our understanding of why that is, we investigate drivers, barriers, and outcomes associated with both broadly defined environmental sustainability initiatives and industrial symbiosis from an organizational context pe
Numerous applications of membrane processes are feasible in pulp mills. The challenges inherent in these applications vary. High pH and high temperature call for ceramic membranes when treating spent pulping liquors, whereas low-cost membranes are needed when treating dilute process streams in mechanical pulp mills. Ultrafiltration has been used to recover lignosulphonate in sulphite pulp mills fo
Throughout history packages are used to contain, store and transport goods and products. In early days it was a matter of gathering and storing locally, whereas in today’s global enterprises packaging is an important issue in the operational management in networks of functions and/or divisions, often separated geographically around the world. Packaging has become a part of the process of efficient
Irradiating a flame by microwave radiation is one of several plasma-assisted combustion (PAC) technologies that can be used to modify the combustion chemical kinetics in order to improve flame-stability and to delay lean blow-out. One practical implication is that engines may be able to operate with leaner fuel mixtures and have an improved fuel flexibility capability including biofuels. In additi

The concept of “edges” challenges this view: given the multiple dimensions that teaching and learning encompass, there will always

Arbetet omfattar uppföljningav ställda kriterier förlåg klimatpåverkan från betong vid upphandling av betongstommeför brf. Viva i Göteborg. Kriterierna följdes upp dels genom att LCA studien som genomförtsunder programskedet uppdaterades med data för den färdigupphandlade byggnadenoch dels genom att interljuva ett urval av aktörer för att få en inblick över hur branschen ser på de ställda kraven. This work includes monitoring of set criteria for low climate impact from concrete in procurement of concrete structures for brf. Viva in Gothenburg. The criteria were followed up by updating the LCA study performed during the program phase with new data for the completed building, plus a selection of the project stakeholders were also interviewed to gain an insight into how the industry received
This report is a result of a Master Thesis made at Volvo 3P and the Department of Advance Engineering and Concepts. The thesis is a part of the education in Mechanical Engineering at the Department Design Sciences, for the Division of Machine Design at Lund University. Volvo 3P is involved in a project regarding a new patented manufacturing method that is under development. The manufacturing metho
Background: Magnetic resonance imaging (MRI) is recommended by guidelines to evaluate the severity of brain ischemia after cardiac arrest for functional outcome prediction. However, standardized assessment criteria are lacking. We have developed a semi-quantitative Cardiac Arrest Brain Ischemia (CABI) score to assess the extension of brain ischemia on MRI. Objectives: To evaluate the prognostic pe
This chapter explores the evolution and effectiveness of Sweden's climate policy mix for decarbonizing the transport sector—a major contributor to national greenhouse gas (GHG) emissions. Despite early leadership in climate policy, Sweden faces challenges in aligning policy implementation with ambitious goals, such as a 70 % reduction in transport emissions by 2030. The chapter shows that Sweden's
RATIONALE: Caffeine is commonly used in preterm infants to improve respiratory function. However, the optimal strategies for caffeine initiation have not been defined. OBJECTIVES: To evaluate the relative benefits and harms of different indications and timings for caffeine initiation in preterm infants. SEARCH METHODS: We searched MEDLINE, Embase, CENTRAL, and trial registries up to 23 April 2025.
The third round of NDCs were due to be released in the lead up to COP30 in November 2025, with parties to the Paris Agreement set to detail commitments to more ambitious emissions reductions. The content of past NDCs have differed greatly depending on which country is submitting the document, especially in how well gender is integrated across actions for NDC implementation. Previous studies show t
Due to their dependence on a single crop, agricultural frontiers are often considered to be formed through phases of 'boom and bust'. These phases are closely related to fluctuations in world market prices of the commodity that constitutes the frontier's economic basis. This paper demonstrates how although migration patterns and economic growth are conditioned by world market dynamics, local socio
Future wireless communications will rely on multiple-input multiple-output (MIMO) beamforming operating at millimeter wave (mmWave) frequency bands to deliver high data rates. To support flexible spatial processing and meet the demands of latency-critical applications, it is essential to use fully digital mmWave MIMO beamforming, which relies on accurate channel estimation. However, ensuring power
I examine the relationship between reproductive success and marker-based relatedness (MBR; inferred from variation at 21 microsatellite loci) of pair-mates in a semi-isolated population of great reed warblers (Acrocephalus arundinaceus) over a 12 year period. There was a negative relationship between egg-hatching success and MBR, but no association between MBR and three other components of fitness
The base for the study is laid during an internship at a regional office in Brussels. The study initially concentrates on the function and activities of different regional offices located in Brussels, in order to answer the core question. The main focus is to reveal an eventual change of cooperation patterns between different regional offices, and in particular the eventual redirection away from
