Assessment of coal mine water in Moatize by static and leaching tests

Acid mine drainage (AMD) is one of the most serious environmental problems in mining worldwide. One of the largest unexploited coal basins in the world is located in Moatize. It contains about 23 billion metric tonnes of coal. The coal mining there is done in riparian sections of the Zambezi River basin, making it particularly vulnerable to pollution. Much of the coal waste is produced by a number

Methodologies for feminist peace research

This chapter focusses on the question of “how” in research. It argues that critical methodologies are key to the development of theory in feminist peace research. The chapter discusses some central skills and sensitivities of the feminist peace researcher such as reflexivity, critical scrutiny, and attendance to power relations. It outlines three broad methodological approaches that are particular

A systematic review of outcome reporting in incisional hernia surgery

BACKGROUND: The incidence of incisional hernia is up to 20 per cent after abdominal surgery. The management of patients with incisional hernia can be complex with an array of techniques and meshes available. Ensuring consistency in reporting outcomes across studies on incisional hernia is important and will enable appropriate interpretation, comparison and data synthesis across a range of clinical

Considerable variation of trough β-lactam concentrations in older adults hospitalized with infection—A prospective observational study

In older adults, few studies confirm that adequate concentrations of antibiotics are achieved using current dosage regimens of intravenous β-lactam antibiotics. Our objective was to investigate trough concentrations of cefotaxime, meropenem, and piperacillin in older adults hospitalized with infection. We included 102 patients above 70 years of age. Total trough antibiotic concentrations were meas

Svenska jordnaturer 1718–1865 : En kvantitativ översikt

The legal status of land had important consequences in pre-industrial societies, and Sweden was no different. Here land was broadly divided into the three categories of free-hold, crown land and noble land, which, in turn, were divided into several sub-categories, each with its own legal and practical consequences. In this paper I present, for the first time, a comprehensive dataset for 17 such su

Anisotropic dynamics of magnetic colloidal cubes studied by X-ray photon correlation spectroscopy

Herein we present our results on the investigation of the influence of external magnetic fields on the anisotropic collective dynamics of core/shell colloidal cubes having a hematite core and silica shell. Owing to the hematite cores, these micrometer-sized particles possess permanent dipole moments, which are at an angle with respect to the long diagonal of the cubes. As a result, they self-assem

On cost design in applications of optimal control

A new approach to feedback control design based on optimal control is proposed. Instead of expensive computations of the value function for different penalties on the states and inputs, we use a control Lyapunov function that amounts to be a value function of the optimal control problem with suitable cost design and then study combinations of input and state penalty that are compatible with this v

Search for Higgs boson production in association with a high-energy photon via vector-boson fusion with decay into bottom quark pairs at √s = 13 TeV with the ATLAS detector

A search is presented for the production of the Standard Model Higgs boson in association with a high-energy photon. With a focus on the vector-boson fusion process and the dominant Higgs boson decay into b-quark pairs, the search benefits from a large reduction of multijet background compared to more inclusive searches. Results are reported from the analysis of 132 fb−1 of pp collision data at s

Immune responses against oxidized LDL as possible targets for prevention of atherosclerosis in systemic lupus erythematosus

Patients suffering from systemic lupus erythematosus (SLE) are at increased risk of developing cardiovascular disease (CVD) and traditional therapies including statins provide insufficient protection. Impaired removal of apoptotic material is a common pathogenic mechanism in both SLE and atherosclerosis and is considered to be a key factor in the development of autoimmunity. Since oxidized LDL and

Fewer reoperations after posterolateral plate positioning compared with lateral plate positioning in ankle fractures—a retrospective study on 453 AO/OTA 44-B injuries

Introduction: Ankle fractures are commonly treated by open reduction and internal fixation with plate and screws. Unplanned return to theatre is common, in many cases to extract prominent osteosynthesis material from the lateral malleolus as swelling subsides. We hypothesised that patients operated with a posterolateral plate placement on the lateral malleolus would have fewer reoperations, and fe

130 år av brokigt folkliv

Malmö fick landets första folkpark redan för 130 år sedan. Idag, på parkens födelsedag, reflekterar tre kulturgeografer över anläggningens historia och dess roll i dåtid, nutid och framtid.

Immune response and gut microbiota of mice on a diet mimicking eating habits of elderly with risk of malnutrition development

The number of elderlies is increasing but prevalence of malnutrition has been reported. The aim of the study was to determine the significance of short-term nutritional deficiencies in mice. Immune status was assessed through flow cytometry of leucocytes in Peyer’s patches (PP) and mesenteric lymph nodes (MLN), and intestinal microbiota was evaluated by terminal restriction fragment length polymor

Validation of factor VIII activity for monitoring standard and extended half-life products and correlation to thrombin generation assays

Introduction: Monitoring replacement therapy with standard and extended half-life (EHL) products is challenging, since one-stage assay (OSA) and chromogenic substrate assay (CSA) results may differ significantly. Recent recommendations include local validation of each new product with recovery within 20–30%, depending on activity level. Aim: To validate factor VIII (FVIII) activity for monitoring

Skyddszoner i jordbruket – betalt för resultat?

Många lantbrukare utför frivilliga åtgärder för att gynna miljön. Som kompensation för kostnader och inkomstbortfall får lantbrukarna en miljöersättning. Ersättningen är åtgärdsbaserad, vilket innebär att dess storlek beror på vilken typ av åtgärd det handlar om och dess omfattning. Denna studie undersöker effekten av att istället göra ersättningar resultatbaserade, det vill säga basera dem på hur

Identification of a serum biomarker signature associated with metastatic prostate cancer

Purpose: Improved early diagnosis and determination of aggressiveness of prostate cancer (PC) is important to select suitable treatment options and to decrease over-treatment. The conventional marker is total prostate specific antigen (PSA) levels in blood, but lacks specificity and ability to accurately discriminate indolent from aggressive disease. Experimental design: In this study, we sought t

Rapid diagnostic testing for SARS-CoV-2 : Validation and comparison of three point-of-care antibody tests

With the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a need for diagnostic tests has surfaced. Point-of-care (POC) antibody tests can detect immunoglobulin (Ig) G and M against SARS-CoV-2 in serum, plasma, or whole blood and give results within 15 min. Validation of the performance of such tests is needed if they are to be used in clinical practice. In this study, we

A Novel Joint Points and Silhouette-Based Method to Estimate 3D Human Pose and Shape

This paper presents a novel method for 3D human pose and shape estimation from images with sparse views, using joint points and silhouettes, based on a parametric model. Firstly, the parametric model is fitted to the joint points estimated by deep learning-based human pose estimation. Then, we extract the correspondence between the parametric model of pose fitting and silhouettes in 2D and 3D spac

A novel delivery system for supraglottic atomization allows increased lung deposition rates of pulmonary surfactant in newborn piglets

Background: Earlier attempts to deliver effective lung doses of surfactant by aerosolization were unsuccessful, mostly because of technical shortcomings. We aimed at quantifying the lung deposition of poractant alfa with a new supraglottic delivery system for surfactant atomization in an experimental neonatal model. Methods: The method involved six sedated 1-day-old piglets lying in the lateral de
