Wear Mechanisms in Cutting Tools for Machining Applications : Interfacial Phenomena, Characterization, and Relation to Performance

Metal cutting technology plays an important role in the automotive and aeronautic sectors, both of whichare important for the Swedish economy. Both make use of traditional grey cast iron and difficult-to-machine materials like titanium alloys and compacted graphite iron. The tools used to machine thesematerials wear at varying rates depending on factors such as contact temperature, pressure, and t

Ambient dose equivalent rates of gamma radiation from natural radionuclides and 137Cs at grasslands and forests in the area of the Belarusian NPP in the pre-commissioning period (2019)

In situ gamma-spectrometric measurements were performed at grasslands (45 plots) and forests (6 plots) in the vicinity of the Belarusian nuclear power plant in September–October 2019. The aim of the study was to evaluate the baseline level of ambient dose equivalent rates of gamma radiation from natural radionuclides and 137Cs in the period preceding the commissioning of the NPP. The study reveale

Sensitivity and resolution response of optical flow-based background-oriented schlieren to speckle patterns

The degraded resolution and sensitivity characteristics of background-oriented schlieren (BOS) can be recovered by utilizing an optical flow (OF)-based image processing scheme. However, the background patterns conventionally employed in BOS setups suit the needs of the cross-correlation approach, whereas OF is based on a completely different mathematical background. Thus, in order to characterize

Payments to healthcare organisations reported by the medical device industry in Europe from 2017 to 2019 : An observational study

Objective: Medical device industry payments to healthcare organisations (HCOs) can create conflicts of interest which can undermine patient care. One way of addressing this concern is by enhancing transparency of industry financial support to HCOs. MedTech Europe, a medical device trade body, operate a system of disclosure of education payments to European HCOs. This study aimed to characterise pa

Tuning the Josephson diode response with an ac current

Josephson diodes are superconducting elements that show an asymmetry in the critical current depending on the direction of the current. Here, we theoretically explore how an alternating current bias can tune the response of such a diode. We show that for slow driving there is always a regime where the system can only carry zero-voltage dc current in one direction, thus effectively behaving as an i

The African Regional Greenhouse Gases Budget (2010–2019)

As part of the REgional Carbon Cycle Assessment and Processes Phase 2 (RECCAP2) project, we developed a comprehensive African Greenhouse gases (GHG) budget covering 2000 to 2019 (RECCAP1 and RECCAP2 time periods), and assessed uncertainties and trends over time. We compared bottom-up process-based models, data-driven remotely sensed products, and national GHG inventories with top-down atmospheric

Using the Net-Map tool to analyze stakeholder networks in the city region food systems of seven European cities

The current global food system is characterized by anonymity in the value chain, global food trade, loss of knowledge about food sources, and a distant producer-consumer relationship. In addition, the negative environmental impacts of the agricultural sector, such as pollution, degradation of soil and water quality, loss of biodiversity, and significant greenhouse gas emissions, make this sector a

Stories that will make you blush? Erotic audio fiction on the verge between privacy and publicness

This article focuses on the rapidly growing Swedish market of app-based audio erotic fiction through an analysis of two significant apps and publishers: Blanche Stories and Ava Stories. We explore audio erotica apps as devices of both literature, pleasure and intimate sonic connectivity. First, we discuss the specific affordances of the born-audio format, its flexible and mobile forms of listening

Critical survival periods in prostate cancer in Sweden explored by conditional survival analysis

Backround: We wanted to characterize conditional survival in prostate cancer (PC) in Sweden around and after 2005 when the vast increase in incidence due to the opportunistic testing for prostate specific antigen (PSA) culminated. We hypothesize that analyzing survival data during that time period may help interpret survival trends. We focus on stage-specific analysis using conditional survival in

Restrictive practices in community services for people with intellectual disabilities at risk of behaviours that challenge : insights and omissions of the Disability Royal Commission

People with intellectual disabilities commonly experience violent, abusive, and restrictive contexts, particularly those who are at risk of behaviours that challenge, behaviours that often are a sign of trauma, fear, pain, and loss of power. For example, the use of physical restraint and psychotropic medication to manage behaviours labelled as challenging is prevalent in services for people with i

Optimization of coal desulfurization method by sub/supercritical fluid extraction with binary mixtures of carbon dioxide and ethyl lactate as a solvent

Coal combustion for energy results in the emission of air pollutants such as NOx and SOx, which negatively affect human health and the environment. Reducing toxic gas emissions and ash production is needed to achieve cleaner coal. This study aimed to develop an extraction method for desulfurizing coal with non-toxic solvents before combustion. Mixtures of sub/supercritical carbon dioxide and ethyl

ANALYSING WHETHER COMPANY X SHOULD IMPLEMENT A WAREHOUSE MANAGEMENT SYSTEM

A Warehouse Management System (WMS) is a software that tracks and manages warehouse activities. The first WMS was introduced in 1975 and today the WMS market is valued at over USD 3 billion. Most warehouses use one as quality assurance becomes unlikely plausible without software support. This thesis focuses on Company X, who are the third-largest manufacturer by revenue in their industry and a

Oral contraceptive use in women with spina bifida in Sweden

BACKGROUND: Thanks to improved medical care, individuals with spina bifida (SB) live well into adulthood and go through the process of reproductive maturation and the development of sexual desires. However, access to reproductive counselling and contraceptive use has been reported to be lower for women with physical and intellectual disabilities compared to the general population.OBJECTIVE: We inv

Protein-Surfactant Interactions in Complex Systems : Study of Physical Stability of Proteins and Peptides

My objective has been to characterize protein-surfactant interactions in pharmaceutically relevant formulations. Thus, the behavior of selected excipients, proteins and peptides has been studied as the system in question is driven to the verge of instability in different manners; by inducing aggregation, by inducing surfactant complexation, or by inducing precipitation by increasing ionic strength

Workplace interventions to reduce the risk of SARS-CoV-2 infection outside of healthcare settings

Background: Although many people infected with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) experience no or mild symptoms, some individuals can develop severe illness and may die, particularly older people and those with underlying medical problems. Providing evidence-based interventions to prevent SARS-CoV-2 infection has become more urgent with the potential psychological toll i

Investigations of mIPN tissue interactions using fluorescent probes

Several millions of people worldwide are affected by bowel diseases and necessitate gastrointestinal surgery. Anastomosis is the union of two healthy ends of the bowel achieved by suture or stapling. One of the most feared complications after surgery are anastomotic leaks which occur in around 10 % of patients. The unintended breakdown of the newly created connection can lead to leakage of digestiToday in our world, there are several million human beings that are affected by bowel diseases that necessitate surgery. This specific procedure is known as anastomosis (gastrointestinal surgery). This surgical operation is the union of two healthy ends of the bowel that is achieved by either suture or stapling. However, complications can occur; around 10 % of the patients that have undergone the
