Predictions of Spray Combustion using Conventional Category A Fuels and Exploratory Category C Fuels

Aviation currently contributes about 3% of the world’s CO2 emissions, 5% of the global warming, and 35% of the trade. Reducing the emissions and the global warming from aviation is thus essential. Many approaches to achieve this goal are underway, including H2, fuel cells, and batteries, but also by replacing the fossil jet fuel with sustainable jet fuel from non-fossil feedstocks. This involves m

Do Exporters Import Gender Inequality?

We examine whether exposure to gender inequality at export destinations affects the gender wage gap in exporting firms. We motivate the analysis through a stylized model where wages depend on worker productivity, and men have a comparative advantage when trading with gender-unequal countries due to customer discrimination. Empirically, we use high-quality matched employer-employee data from Sweden

A Sound Approach Toward a Mobility Aid for Blind and Low-Vision Individuals

Det finns runt 100 000 blinda och kraftigt synnedsatta individer (BKSI:er) i Sverige. Sådan synnedsättning leder till en kraftigt minskad förmåga för självständig förflyttning och lägre livskvalité, med ökad risk för arbetslöshet, trafikolyckor, en stillasittande livsstil och depression. Hälften av alla käpp- och hundanvändare är med om en huvudkollision årligen, och drygt var tredje för en fallolReduced independent mobility of blind and low-vision individuals (BLVIs) cause considerable societal cost, burden on relatives, and reduced quality of life for the individuals, including increased anxiety, depression symptoms, need of assistance, risk of falls, and mortality. Despite the numerous electronic travel aids proposed since at least the 1940’s, along with ever-advancing technology, the m

Long-term exposure to residential transportation noise and mortality : A nationwide cohort study

Studies have indicated that transportation noise is associated with higher cardiovascular mortality, whereas evidence of noise as a risk factor for respiratory and cancer mortality is scarce and inconclusive. Also, knowledge on effects of low-level noise on mortality is very limited. We aimed to investigate associations between road and railway noise and natural-cause and cause-specific mortality

Exposure to transportation noise and risk for cardiovascular disease in a nationwide cohort study from Denmark

BACKGROUND: Transportation noise increases the risk of ischemic heart disease (IHD), but few studies have investigated subtypes of IHD, such as myocardial infarction (MI), angina pectoris, or heart failure. We aimed to study whether exposure to road, railway and aircraft noise increased risk for ischemic heart disease (IHD), IHD subtypes, and heart failure in the entire adult Danish population, in

Long-Term Exposure to Transportation Noise and Risk for Type 2 Diabetes in a Nationwide Cohort Study from Denmark

BACKGROUND: Epidemiologic studies have linked transportation noise to increased morbidity and mortality, particularly for cardiovascular outcomes. However, studies investigating metabolic outcomes such as diabetes are limited and have focused only on noise exposures estimated for the loudest residential façade.OBJECTIVES: We aimed to examine the influence of long-term residential exposure to trans

Pre- and postnatal exposure to parental smoking and allergic disease through adolescence

OBJECTIVES: To examine the role of prenatal and postnatal second-hand tobacco smoke (SHS) exposure on asthma, rhinitis, and eczema development up to 16 years of age.METHODS: A birth cohort of 4089 children was followed for 16 years. Information on parental smoking habits, lifestyle factors, and symptoms of allergic disease was gathered using repeated parental questionnaires. Generalized estimating

Long-term exposure to transportation noise and risk for atrial fibrillation : A Danish nationwide cohort study

BACKGROUND: Epidemiological studies have linked transportation noise and cardiovascular diseases, however, atrial fibrillation (AF) has received limited attention. We aimed to investigate the association between transportation noise and AF risk.METHODS: Over the period 1990-2017 we estimated road and railway noise (Lden) at the most and least exposed façades for all residential addresses across De

Cohort profile : The Swedish Tattoo and Body Modifications Cohort (TABOO)

PURPOSE: The Swedish Tattoo and Body Modifications Cohort (TABOO) cohort was established to provide an infrastructure for epidemiological studies researching the role of tattoos and other body modifications as risk factors for adverse health outcomes. It is the first population-based cohort with detailed exposure assessment of decorative, cosmetic, and medical tattoos, piercing, scarification, hen

Residential exposure to transportation noise in Denmark and incidence of dementia : national cohort study

OBJECTIVE: To investigate the association between long term residential exposure to road traffic and railway noise and risk of incident dementia.DESIGN: Nationwide prospective register based cohort study.SETTING: Denmark.PARTICIPANTS: 1 938 994 adults aged ≥60 years living in Denmark between 1 January 2004 and 31 December 2017.MAIN OUTCOME MEASURES: Incident cases of all cause dementia and dementi

Transportation noise and risk of stroke : a nationwide prospective cohort study covering Denmark

BACKGROUND: Studies on transportation noise and incident stroke are few and inconclusive. We aimed to investigate associations between road-traffic and railway noise and the risk of incident stroke in the entire Danish population.METHODS: We estimated road-traffic and railway noise (Lden) at the most and least exposed façades for all residential addresses across Denmark (2.8 million) for the perio

Accelerated permafrost thaw and increased drainage in the active layer : Responses from experimental surface alteration

Erosion and infrastructure in the Arctic can change the thickness of the active layer which can subsequently alternate the thermal-hydrological regime and change the drainage patterns on slopes. Previous studies have shown that drainage can either decrease due to the movement of water occurring in deeper soil layers with lower permeability or increase due to the formation of features like gullies

Genetically adjusted PSA levels for prostate cancer screening

Prostate-specific antigen (PSA) screening for prostate cancer remains controversial because it increases overdiagnosis and overtreatment of clinically insignificant tumors. Accounting for genetic determinants of constitutive, non-cancer-related PSA variation has potential to improve screening utility. In this study, we discovered 128 genome-wide significant associations (P < 5 × 10 -8) in a multi-

Percutaneous access of an intraoperatively recanalized mid-superficial femoral artery for distal lower limb revascularization

A 61-year-old male patient presented with rest pain and ulceration in his left leg 1 week after a hybrid procedure with bilateral external iliac stenting, common femoral artery thromboendarterectomy, and left-sided femoral popliteal bypass with an in situ saphenous vein. The bypass had been stented intraoperatively but had again become occluded directly after surgery. In the present report, we dem

Infective popliteal artery aneurysm by Streptococcus equi : An unusual pathogen

We report the case of a 63-year-old man who presented with a 2-week complaint of lower extremity pain, swelling, and low-grade fever after an episode of septic arthritis in the ipsilateral knee. The investigation showed a rapidly expanding popliteal artery aneurysm (PAA). The rare clinical entity of an infective PAA was suspected and was confirmed by the cultures obtained at the right femoropoplit

The role of manual gestures in second language comprehension : A simultaneous interpreting experiment

Manual gestures and speech form a single integrated system during nativelanguage comprehension. However, it remains unclear whether this hold forsecond language (L2) comprehension, more specifically for simultaneousinterpreting (SI), which involves comprehension in one language and simultaneousproduction in another. In a combined mismatch and priming paradigm,we presented Swedish speakers fluent i

Diagnostic and Prognostic Value of Stress Cardiovascular Magnetic Resonance Imaging in Patients With Known or Suspected Coronary Artery Disease : A Systematic Review and Meta-analysis

IMPORTANCE: The clinical utility of stress cardiovascular magnetic resonance imaging (CMR) in stable chest pain is still debated, and the low-risk period for adverse cardiovascular (CV) events after a negative test result is unknown.OBJECTIVE: To provide contemporary quantitative data synthesis of the diagnostic accuracy and prognostic value of stress CMR in stable chest pain.DATA SOURCES: PubMed

Patterns in child stunting by age : A cross-sectional study of 94 low- and middle-income countries

Child stunting prevalence is primarily used as an indicator of impeded physical growth due to undernutrition and infections, which also increases the risk of mortality, morbidity and cognitive problems, particularly when occurring during the 1000 days from conception to age 2 years. This paper estimated the relationship between stunting prevalence and age for children 0-59 months old in 94 low- an

Race in clinical trials in Sweden: how regulatory and medical standards in clinical research trump the post-racial discourse

The post-racial discourse that permeates many Western European countries depicts society as having moved beyond race concepts and classifications. This article focuses on Sweden, a country that, in line with the post-racial thinking, declares race to be an offensive and unscientific concept. The article investigates what happens when this post-racial discourse meets clinical research standards tha
