The European Union (EU) has recently presented several new legal proposals for promoting ecodesign and product labeling. The aim is to harmonize national practices and rules in the EU, to regulate issues like product lifetime and repairability in a more comprehensive way, to introduce new tools like digital product passports, and to introduce labeling schemes for repairability and durability. In p

Background Parenthood is consistently identified as a protective factor for suicidal behavior. However, it remains unclear whether this relationship varies as a function of sex, age, time since birth, number of children, and other risk/protective factors. Methods We used Cox proportional hazards models to describe the relationship between the birth of up to four children and suicide attempt (SA) r

This paper summarized the efforts performed to understand decay heat estimation from existing spent nuclear fuel (SNF), under the auspices of the Working Party on Nuclear Criticality Safety (WPNCS) of the OECD Nuclear Energy Agency. Needs for precise estimations are related to safety, cost, and optimization of SNF handling, storage, and repository. The physical origins of decay heat (a more correc

Exposure to engineered nanomaterials (ENMs) at the workplace can adversely affect human health via inhalation. Occupational exposure limits (OELs) for specific ENMs remain scarce due to a lack of nano-specific data and consensus on the most appropriate dose metric for exposure assessment. In 2022, recommendations were provided on how to derive Health-based Nano Reference Values (HNRVs) for differe

While a naive algorithm for multiplying two 2 × 2 matrices requires eight multiplications and four additions, Strassen showed how to compute the same matrix product using seven multiplications and 18 additions. Winograd reduced the number of additions to 15, which was assumed to be optimal. However, by introducing a change of basis, Karstadt and Schwartz showed how to lower the number of additions

Objectives: Our aim was to compare direct costs for single pill combinations (SPCs) and free-drug combinations for hypertension treatment. Methods: We focused on Australia as a case study and reviewed total costs, and for the patient and government. We reviewed the Australian “Pharmaceutical Benefits Scheme item drug map” considering different thresholds for the government safety net. Total costs

Few existing studies have delved into individual-level attitudes towards the exchange of sexual services for payment, leaving a significant gap in our understanding. Various studies have speculated about how certain demographic factors and attitudes may shape people's perceptions of causes and consequences relating to such exchanges, but none have directly investigated this topic. To bridge this g

Background: Minimising time from injury to hospital admission is considered a key factor in trauma. Trauma care is often centralised to hospitals, which, because of their urban location, make treatment more accessible to patients in densely populated areas. If prehospital time increases with declining population density, an effect on mortality could hence be present. The primary aim of this study

Improving the catalytic performance in the hydrodeoxygenation (HDO) of lignin oils to produce liquid fuels, while meeting industrial requirements, is important for addressing current environmental challenges. In the present study, the promoting effects of noble metals (Pd, Pt, and Ir) on the performance of the Ni–Mo/CeLa/Al2O3 catalyst were investigated in the HDO of a lignin-derived pyrolysis oil

Artificial intelligence (AI) methods are powerful tools for biological image analysis and processing. High-quality annotated images are key to training and developing new algorithms, but access to such data is often hindered by the lack of standards for sharing datasets. We discuss the barriers to sharing annotated image datasets and suggest specific guidelines to improve the reuse of bioimages an

Activity of bats at an old wind park four km off the island of Gotland in the Baltic Sea was monitored during 50 nights from August to October 2013, using an automatic bat detector (Pettersson D500-X) mounted on one of the turbines. Single individuals or pairs of common noctules Nyctalus noctula were recorded on five occasions only (26 and 27 August), all in calm weather and when little or no roto

This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in the Holocene, similar to 6 and similar to 0.2 k BP in Europe. We apply We apply the Rossby Centre regional climate model RCA3, a regional climate model with 50 km spatial resolution, for both time periods, considering three alternative descriptions of the past vegetation

How human exposure levels of air pollutants are related to health status is an issue of great importance for e.g. infrastructural and urban planning. This study analysed the exposure levels of NO2 for individuals depending on their country of birth. The study was conducted within three different study areas of varying characteristics and extent to decide whether any such associations existed and i

Indolyl substituted pyranyl- and cyclohexenyl molybdenum complexes were synthesised through stereoselective nucleophilic addition of indoles to the corresponding cationic 2H-pyran or cyclohexadiene molybdenum complex. Decomplexation of an allylic molybdneum complex by treatment with iodine gave 1-(4-iodo-2-cyclohexenyl)-1H-indole-3-carbonitrile in high regio-selectivity. A new method for preparati

One important task for the librarians at Physics and Astronomy Library at Lund University is to teach the students about the library and its resources. The traditional lectures and tours of the library just weren’t working. The library competes with many other introductory activities, such as general orientation, and social events. The aim of the Treasure Hunt is to present the library in a useful
