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

Let NDTIME(f(n),g(n)) denote the class of problems solvable in O(g(n)) time by a multi-tape Turing machine using an f(n)-bit non-deterministic oracle, and let DTIME(g(n)) = NDTIME(0, g(n)). We show that if the all-pairs shortest paths problem (APSP) for directed graphs with N vertices and integer edge weights within a super-exponential range { -2Nk+o(1),.,2Nk+o(1)}, k≥1 does not admit a truly subc

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

Ekologisk kompensation innebär att naturvärden som går förlorade på en plats tillförs på en annan plats. Tanken är att exploatering av mark- och vattenområden på så vis ska kunna ske samtidigt som värdefull natur bevaras. Fungerar då styrmedlet som avsett? Ekologisk kompensation kan verka vara en enkel lösning på en svår målkonflikt men en lärdom från andra länder är att måluppfyllelsen ofta är lå

BACKGROUND: Quality of surgical care as a crucial component of a comprehensive multi-disciplinary management improves outcomes in patients with endometrial carcinoma, notably helping to avoid suboptimal surgical treatment. Quality indicators (QIs) enable healthcare professionals to measure their clinical management with regard to ideal standards of care. OBJECTIVE: In order to complete its set of

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

Fast-moving consumer goods (FMCGs) are products that have a short useful lifetime and are typically designed for single or limited uses followed by disposal. The disposable nature of FMCGs combined with ineffective waste recovery systems is causing global environmental problems. Various reusable packaging business models have emerged to tackle these problems; however, their influence is still low

Sixteen landcover classes in a representative Swedish environment were analyzed and classified using one Landsat TM scene and seven ERS-1 SAR.PRI images acquired during 1993. Spectral and backscattering signature separabilities are analyzed using the Jeffries-Matusita distance measure to determine which combinations of channels/images contained the most information. Maximum likelihood, sequential

Purpose – Competence development is a prerequisite for successfully meeting existing and future challenges in the retail sector. However, current human resource development practices are often limited in their scope and offerings. This study sets out to investigate and bring to light informal learning among retail professionals.Design/methodology/approach – This research consists of two explorator

We introduce the combination of digital holographic microscopy (DHM) and antibody microarrays as a powerful tool to measure morphological changes in specifically antibody-captured cells. The aim of the study was to develop DHM for analysis of cell death of etoposide-treated suspension cells. Results/methodology: We demonstrate that the cell number, mean area, thickness and volume were noninvasivel

High-efficiency microfocusing of multi-keV X-rays at synchrotron sources is highly profitable for spatially resolved structural analysis of many kinds. Because radiation from synchrotron sources is typically elongated along the horizontal dimension, generating a microbeam that is isotropic in size requires a carefully designed optics system. Here we report on using a combination of a horizontally

Acquisition of entomological data with high-frequency lidar is an emerging research field in rapid development. The technique offers very high numbers of observations per time unit, suitable for statistical models. In this work, we use a near-infrared Scheimpflug lidar with a sampling frequency of 3.5 kHz to assess the activity of free flying organisms. In-situ measurements were done during the ra

How will higher education and research evolve in the future to produce the high-level knowledge and skilled human capital which underpin sustainable societies?This book explores challenges for the post-knowledge society and economy where major socio-economic change is occurring in tandem with advances in digital technologies. It brings together international authors to discuss scenarios against a

The human genome contains at least 35 genes that encode Golgi sulfotransferases that function in the secretory pathway, where they are involved in decorating glycosaminoglycans, glycolipids, and glycoproteins with sulfate groups. Although a number of important interactions by proteins such as selectins, galectins, and sialic acid-binding immunoglobulin-like lectins are thought to mainly rely on su

Objective: Implantable cardiac monitors (ILR) have an important role in diagnosing unexplained syncope. However, outcomes of primary vs. delayed ILR implantation after initial syncope evaluation have not been explored. Methods: A total of 1705 patients with unexplained syncope were prospectively enrolled in the SYSTEMA (Syncope Study of Unselected Population in Malmö) cohort. Patients who underwen
