This paper presents technical developments for the detection of formaldehyde (CH2O) using laser-induced fluorescence. The easily accessible third harmonic of the Nd:YAG laser at 355 nm was used for excitation of formaldehyde. In order to investigate potential background fluorescence, e.g., from large molecules such as polyaromatic hydrocarbons, special attention was paid to investigating the possi
Online measurements of the raw gas composition, including tars and water, during biomass gasification provide valuable information in fundamental investigations and for process control. Mainly consisting of hydrocarbons, tars can, in principle, be measured using Fourier transform infrared (FT-IR) spectroscopy. However, an instrument subjected to raw gas runs the risk of condensation of tars on opt
Epilepsy is a family of heterogeneous and multifactorial neurological disorders, unified by the occurrence of spontaneous recurrent seizures. Overall, it affects 50 million people worldwide of all ages and genders. Available treatments are only symptomatic and have severe side effects, while they also fail to provide adequate seizure control in a third of the patients. Therefore, a cure is yet to
In recent years there has been a great deal of discussion on the potential for a shift away from modernistic or technocratic approaches to decisionmaking on risk towards more open, inclusive, and deliberative approaches. The authors consider (a) the reasons why some companies have taken the first step in this transition by exploring the potential of more open and communicative approaches to enviro
Wastewater heat recovery upstream of wastewater treatment plants (WWTP) poses a risk to treatment performance, i.e. the biological processes. In order to perform a sustainability analysis, a detailed prediction of the temperature dynamics over the WWTP is needed. A comprehensive set of heat balance equations was included in a plant-wide process model and validated for the WWTP in Linköping, Sweden
ObjectiveOpen and endovascular aortic repair may be complicated by aortic vascular graft or endograft infection (VGEI). Confirming the microbiological aetiology is a key element in providing the best available treatment to patients with a VGEI. The primary aim of this study was to describe the technique of direct aneurysm sac guided aspiration (DASGA) in determining the microbiological aetiology i
Some common Christmas plants are presented with emphasis on Botany and their connection to Christmas. The plants dis- cussed are Picea abies, Euphorbia pulcherrima, Helleborus niger, Viscum album, Ilex aquifo- lium, Schlumbergera sp., Hippeastrum × hor- torum, Hyacinthus orientalis, Lycopodium s.l., and Cladonia stellaris.
Background: Optimal anticoagulation management in patients with myeloproliferative neoplasms (MPN) experiencing splanchnic vein thrombosis (SpVT) requires balancing risks of bleeding and recurrent thrombosis. Objectives: We conducted a systematic review and meta-analysis to assess the incidence of bleeding and thrombosis recurrence in patients with MPN-SpVT. Methods: We included retrospective or p
Following a boom of user-friendly artificial intelligence tools in recent years, AI-enhanced (or manipulated) films have been framed as a serious threat to film archives. The purpose of this article is to trace and critically evaluate how AI artists use algorithmic upscaling to modify early cinema, more particularly surviving films of the film company Swedish Biograph, and how fragments of this co
Critical scholarship has long pointed to the problematic ways in which mainstream International Relations (IR) takes Westphalian state politics to be universally applicable, yet existing analyses fall short of providing an alternative grounding for IR. Departing from the close relationship between medicine and politics, this article advances two arguments. First, Westphalian IR is based on a parti
Musculoskeletal health is essential to health, well-being, and independence across the life course. Musculoskeletal conditions including inflammatory joint diseases, osteoarthritis, back pain, osteoporosis, and fragility fractures are among the greatest causes of disability globally imposing a major burden on health and social care and economic impact also through lost productivity. Despite effect
Modeling of robot motion as dynamical movement primitives (DMPs) has becomean important framework within robot learning and control. The ability of DMPs to adapt online with respect to the surroundings, e.g., to moving targets, has been used and developed by several researchers. In this work, a method for handling perturbations during execution of DMPs on robots was developed. Two-degree-of-freedo
Studying dissolution of oral drug substances is crucial throughout the drug development process. Current methods are time consuming and require large quantities of both the drug and dissolution media. Thus, exploring new methods is highly desirable. UV imaging, an analytical technique based on real-time absorbance measurements, can be used in early drug discovery to study drug dissolution and has
Transylvania’s countryside, characterized by a mostly agrarian society with a rich multicultural heritage is being threatened by Romania’s tendencies of chaotic modernization and rapid urbanization. This research aims to find a viable solution for sustaining the cultural, natural, and social environment in rural Transylvania, by analysing the potential of tourism development. Integrated Rural Tour
Den digitala omställningen har ökat genom åren och har fungerat till en fördel för företag och organisationer generellt. Hastigheten på transformationstillväxten har bibehållits i nutid, vilket har resulterat i att mjukvarusystem utvecklas kontinuerligt. Som en naturlig effekt av detta fenomen, bör aktuella företag alltid ligga i framkant för att förbli konkurrenskraftiga. Studier har visat att pr
Cancer is a widespread and commonly fatal disease in constant need of new treatments. Traditionally, new pharmaceuticals have been tested in 2D models. This is not ideal, as 2D environments do not reflect the in vivo milieu of the cells. Instead, it has been increasingly suggested to implement 3D models, which are thought to be more predictive of in vivo responses to treatment. It has been shown t
Background: environmental impact from health care contribute to a substantial part of the public sector’s consumption based emission of greenhouse gases in Sweden. An issue, recognized by the health care sector itself, is the increasing use of single-use products. Objective: to compare environmental impact and cost differences between a single-use, ResposableTM, and mixed setup of the surgical in
