A growing demand for renewable carbon (C) has led to intensified forest management resulting in the use of forest residues (e.g. canopy, bark or litter layer) as energy sources with potential modifications of soil properties and tree productivity. Because microbes mediate the recycling of C and nutrients sequestered in organic matter, we investigated the effects of organic matter (OM) removal on s
The importance of reducing environmental impacts has gained speed in the contemporary global context. Stabilization/Solidification (S/S) has become a practical method for handling polluted dredged sediments to make them usable as a construction material. This study aims to evaluate the environmental and economic impacts of a 48,586 m2 port, with stabilized dredged sediment, by focusing on the prod
Objectives The objectives of this study are to study the risk of developing cardiac arrhythmia and its subtypes over time in patients with systemic sclerosis (SSc), to assess potential risk factors for arrhythmia in SSc and to explore whether arrhythmia is associated with mortality. Methods We used nationwide Swedish registers to identify patients with incident SSc 2004–2019 and matched general po
Non-pharmacological interventions represent the first-line treatment approach for patients with non-cardiac syncope. These interventions include reassurance of the benign nature of syncope, education about triggers and strategies to avoid them, early recognition of prodromal symptoms, and lifestyle measures to counteract blood pressure falls. Adequate water intake is recommended to avoid hypovolem
Eritreans are currently forcefully conscripted into national service, which is indefinite and requires them to engage in tasks that are beyond a ‘purely military character’. These include economic development activities, work for private companies and even domestic work for their superiors, for which they receive little or no pay. Deserting or evading national service is heavily punished and refug
Background: The use of antiarrhythmic drugs (AADs) in patients with chronic kidney disease (CKD) is complex because impaired renal clearance can cause increased drug levels, and risk of intolerance or adverse events. Due to the propensity for CKD to occur alongside atrial fibrillation/atrial flutter (AF/AFL), it is essential that AAD safety and efficacy are assessed for patients with CKD. Hypothes
A combination of a MEK/ERK-signaling inhibitor and three chromatin-remodeling molecules enhances generation of platelet-producing megakaryocytes in vitro, possibly through direct reprogramming.
This paper presents a joint numerical and experimental study of the ignition process and flame structures in a gasoline partially premixed combustion (PPC) engine. The numerical simulation is based on a five-dimension Flamelet-Generated Manifold (5D-FGM) tabulation approach and large eddy simulation (LES). The spray and combustion process in an optical PPC engine fueled with a primary reference fu
Materials of ionic crystals are ubiquitous in industrial chemistry.For example, materials such as cerium dioixde (CeO2) are used in both self-cleaning ovens and to clean exhaust fumes from cars.Other materials, such as titanium dioixde (TiO2) has been used in the solar-cell industry.So-called garnets are used in several lasers.In common for all of these areas of application, is that they are depen
Postural orthostatic tachycardia syndrome (POTS) is a cardiovascular autonomic disorder characterized by excessive heart rate increase on standing, leading to debilitating symptoms with limited therapeutic possibilities. Proteomics is a large-scale study of proteins that enables a systematic unbiased view on disease and health, allowing stratification of patients based on their protein background.
BACKGROUND: The effect of a treatment that includes frequent changes of the body position for infants with bronchiolitis has not been evaluated, although it is often used in Swedish hospitals. Because of this, a randomised control trial (RCT) has begun with the aim to evaluate this treatment, comparing the effect of an individualised physiotherapy intervention, a non-individualised intervention, a
Background: ‘Collegial Midwifery Assistance’ (CMA) is a clinical practice aiming to reduce severe perineal trauma (SPT) during childbirth. This practice involves two midwives being present during the active second stage of labour rather than one, which is the case in standard care. The effectiveness of CMA was evaluated in the Oneplus trial and a 30% reduction in SPT was shown. Aim: The aim was to
The International Covenant on Civil and Political Rights (‘ICCPR’) is the only human rights treaty that has universal coverage both geographically and in respect of its personal scope, and that includes a specific provision on the rights of minorities, or to be more exact, on the rights of members of minorities. Here the Covenant differs also from the Universal Declaration of Human Rights, which d
BACKGROUND: The purpose of this study was to evaluate if propofol has 5-HT3 antagonistic effects. Ipecacuanha is known to release serotonin (5-HT) in the gastrointestinal tract and therefore ipecacuanha syrup was used to induce nausea and vomiting. The 5-HT3 antagonist ondansetron was used as a control substance. METHOD: Ten healthy male volunteers (20-37 years) were studied on three occasions and
We have reported that epidermal Langerhans cells possess an H+-extruding mechanism signalling their existence in an anaerobic environment. This study highlights the energy metabolism of human epidermis. In their habitual state the keratinocytes contain more lactate than do most other cell types. Their lactate production in vitro is vigorous and independent of oxygen and most of it is released to t
Differential cross sections for Compton scattering from the deuteron were measured at MAX-Lab for incident photon energies of 55 and 66 MeV at nominal laboratory angles of 45degrees, 125degrees, and 135degrees. Tagged photons were scattered from liquid deuterium and detected in three NaI spectrometers. By comparing the data with theoretical calculations in the framework of a one-boson-exchange pot
Popular Abstract in Swedish Förbränning förknippas av många som förlegat. Att utvinna energi genom att ”elda” har människan gjort under årtusenden, men trots det bestod Sveriges totala energiproduktion 2004 till 52 % av förbränning. De flesta bilar, båtar, flyg och i vissa fall även tåg utnyttjar den kemiskt lagrade energin i fossila bränslen. Uppvärmningen av bostäder är inte heller att förringa,The thesis work, aimed at the development of laser-spectroscopic detection schemes, consists of three parts, concerned with the development and application of different techniques. The development of UV filtered Rayleigh scattering (FRS) for thermometry and fuel/air ratio measurements, using a frequency tripled, single-longitudinal-mode alexandrite laser at ~254 nm together with an isotopically en
