In the present study, the operation performance of an ultralow-temperature cascade refrigeration freezer is experimentally researched. The natural refrigerants R290-R170 are adopted as high-temperature and low-temperature fluids. The experimental test is conducted in a type laboratory with a dry bulb temperature of 32.0 °C and a wet bulb temperature of 26.5 °C. Different state monitors are set to

This article measures the impact of the switch to new and more expensive drugs on the aggregate drug expenditure (both prescription and nonprescription) in Sweden during the period 1974 to 1991, and also on the disaggregated expenditure for 3 medical areas: asthma, hypertension and peptic ulcer disease. During the period studied, nominal drug expenditure increased 6-fold. The retail price index of

Background: Adult children are often key carers of frail older parents providing care for a long period of time in different care contexts. However, research concerning adult children’s caregiving experiences, from providing home-based care to facing the death of a parent in a nursing home is sparse. Thus, the aim was to explore the transition from living at home to moving into and living in a nur

BACKGROUND: Many lifestyle factors have been associated with the metabolic syndrome (MetS). However, most of these studies have not considered the potential impact of obesity and have often only investigated one lifestyle factor at the time. We aimed to investigate the interplay between body mass index (BMI) and MetS with respect to multiple lifestyle factors.METHODS: BMI and MetS [National Choles

Groundwater contamination by nitrate is a common problem in many parts of the world. The agriculturally important Shimabara district in Nagasaki, Japan, is experiencing this problem. The general source of drinking water of the study area is groundwater and consequently the nitrate contamination is a significant problem. For this reason, a groundwater investigation was performed and water samples w

Under istider, när stora mängder havsvatten var bundet i inlandsisar, var den globala havsnivån lägre än idag och stora delar av kontinentalsockeln torrlagd. Den senaste istiden (cirka 115 000–12 000 år sedan) var inget undantag, då torrlagda områden utvecklades till ekologiskt rika kustområden som möjliggjorde människans spridning över världen. När inlandsisarna smältesteg havsnivån och dessa lanDuring times of lower global sea level, vast areas of the coastal shelf were exposed and converted into ecologically diverse coastal landscapes that wereattractive for human occupation. The landscapes were subsequently flooded during the deglaciation, but well-preserved remains of these landscapes andtheir inhabitants can today be found on the seafloor. In the southern Baltic Basin, where the comp

Background: Trajectories of asthma and allergy in children are heterogeneous and commonly derived from parental report of disease or clinical records. This study combined parental-reported and register-based dispensed medication data to characterize childhood trajectories of co-existing asthma, allergic rhinitis, and eczema. Methods: From a Swedish population-based birth cohort (N = 5654), survey

Background: Swedish healthcare is in a period of transition with an expanding private sector. This study compares quality of outcome after groin hernia repair performed in a public or private healthcare setting. Methods: A cohort study based on data from the Swedish National Hernia Register combined with Patient-Reported Outcome Measures (PROMs) 1 year after groin hernia repair. Between September

The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, generates a large amount of waste heat. Some of this heat is partially recovered and is used for heating one of the main buildings during the furnace operation. However, around 2,000 MWh is wasted annually due to unavailability of any storage system. This work studies in detail four different solutions to utilize t

Detta är den trettonde årsrapporten från Svensk Dagfjärilsövervakning, ett nationellt miljö-övervakningsprogram som koordineras av Lunds universitet på uppdrag av Naturvårdsverket sedan 2010. Svensk Dagfjärilsövervakning är ett samarbete mellan Sveriges Entomologiska Förening, Naturvårdsverket, Lunds universitet, Sveriges lantbruksuniversitet och Länsstyrelserna. Verksamheten möjliggörs av frivill

In the beginning of the COVID-19 pandemic, several super spreader events occurred during singing in choirs, which lead to an increased attention to airborne transmission of SARS-CoV-2, the virus causing COVID-19. Since then, aerosol generation from singing has been studied in more detail, however, only from healthy subjects. In this study, we collected aerosol particles in the exhaled breath of 40

Emissions from aviation are expected to grow. With evidence that the International Civil Aviation Organization’s Carbon Offsetting and Reduction Scheme for International Aviation is an inadequate mitigation mechanism, there is interest in upscaling the sector’s climate-related policies. This paper reviews potential aviation emissions mitigation policies against the background of emerging complexit

Based on fieldwork in a sensory science laboratory in Sweden, this paper brings the social aspects of conducting an analytical sensory panel together with consumers’ understandings of the everyday consumption context and existing practices. As part of an interdisciplinary project investigating seaweed as a new food in a Swedish context, this paper explores how seaweed as a new resource is made edi

Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. Modern telescopes, both ground- and space-based, like the Very Large Telescope (VLT) or the James Webb Space Telescope (JWST) will drive forward the

Interactive web-GIS tools play an important role in determining disaster risk assessment which ultimately result in reduction of unexpected damages, cost and saves millions of lives. Disaster management practitioners largely benefited information at their disposal about location where possible incidents are eminent, anticipate the impact and project possible outcomes to help mitigate and organize

Syftet med denna studie var att undersöka effekterna av flotation-REST (Restricted Environmental Stimulation Therapy, en sensoriskt reducerad avslappningsmetod) jämfört med passiv vila med lugnande musik på den subjektiva upplevelsen av fysisk ansträngning, mätt direkt efter högintensiv fysisk aktivitet. Fyrtiofyra deltagare (18 idrottare och 26 icke-idrottare) genomgick båda återhämtningsmetodern

Climate adaptation is necessary to address the impacts of the climate change which is already unavoidable due to past emissions. There is a strong need for knowledge building, for which climate-related knowledge and information needs to be made available through different types of climate services. The aim with this study is to examine how useful climate services are, as a knowledge base for decis
