A new technology has emerged the last decade, based on a new group of materials; Soft Magnetic Composites (SMC), instead of laminated steel that facilitates production of products with more integrated, smaller, lighter, less costly and highly efficient electromagnetic machines. The application of this technology is a change of paradigm regarding integrated design and energy efficiency. This articl
The structure, biosynthesis, and metabolism of proteoglycans in the HL-60 human promyelocytes were studied by metabolic labeling in culture with [35S]sulfate, [3H]glucosamine, [3H]serine, and [3H]leucine. These cells synthesize a single predominant species of intracellular proteoglycan with an approximate molecular weight of 100,000. The cells contain about 1 μg of proteoglycan/million cells. The
All players in Swedish soccer teams are required to have insurance in the same company. from the archives of the insurance company, all 3,735 injuries reported in 1986 in 188,152 Swedish soccer players were reviewed. of these, 937 were knee injuries. All players were asked by mail to fill in a questionnaire and 83 percent replied. the patient records from the different hospitals were requested. th
The built environment accounts for a significant share of energy consumption and energy efficiency in this sector is important for the Swedish environmental objectives. Only a limited share of the total new construction of multifamily houses are constructed as low-energy buildings. Current building regulations lay down requirements for energy efficiency for new construction, and these will be tigh
The present paper provides an extensive literature review on water related health issues in Central Asia. Even though the per capita amount of available freshwater is substantial in all Central Asian states the uneven distribution in time and space creates problems for water availability. Due to this, the Central Asian economies are developing under increasing water deficiency. The degradation of
This thesis examines the strategies developed by José Martí for a prosperous Spanish American future in the end of the 19th century. In 1875, which is the starting point of the thesis, most nations in Spanish America had freed themselves from colonial rule and now stood before the challenge of finding a beneficial place within the international division of labour. Martí observed that centuries of
Mango production plays a vital role in rural livelihoods in Mozambique, yet post-harvest losses remain high, ranging from 25% to over 50%, due to inadequate preservation methods. Improved solar drying technologies offer a sustainable solution by extending shelf life and enhancing product quality. However, their adoption among smallholder mango farmers remains limited. This study investigates the k
The international humanitarian system has, since the 19th century, been activated during large-scale disasters when the capacities of the affected countries are overwhelmed. It comprises international humanitarian organizations (IHOs) and is funded by a variety of donors. Recently, this system has faced increasing criticism, mainly because of its failure to empower and include local and national a
Betong används över hela världen men tillverkningen ger stora koldioxidutsläpp. I detta arbete undersöktes hur tillsats av slagg, en biprodukt från metallproduktion, påverkade betongens tidiga hållfasthet och kunde ge nya möjligheter att bygga mer hållbart. Betong är världens mest använda byggmaterial tack vare sin hållbarhet, formbarhet och motståndskraft mot fukt, mögel och brand. Men produktionConcrete is the most widely used construction material worldwide, with an annual global consumption of approximately 30 billion tons and 14–15 million tons in Sweden in 2022. Its popularity stems from its durability, robustness, formability, and resistance to moisture, mold,fire, and sound. However, concrete production has a significant environmental impact, largely due to cement manufacturing, wh
This study systematically investigates the passivation and dissolution mechanisms of TC4 (Ti-6Al-4V) in 3.5 wt% NaCl solution using in situ electrochemical atomic force microscopy (ECAFM), complemented by X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS). Potentiodynamic polarization initially identified the electrochemical behavior of TC4, delineating passive, dissolv
Tattoo ink on the European market has been reported to contain many human toxicants, which has raised concerns about health effects. Clarifying the exposure distribution in the population is key to understanding potential public health implications. We investigated the prevalence of tattoos in a population-based Swedish cohort of 13 046 individuals aged 20–68 years with exposure data collected thr
Background: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2
Background: Uncomplicated lower urinary tract infections (UTIs) occur in approximately 50% of women, and 20–30% experience recurrent UTI. Data on UTIs and quality of life (QoL) in Europe are limited. Methods: This was an anonymous, self-administered web-based survey conducted in 5 countries (Germany, Switzerland, Poland, Russia and Italy), on adult women who had experienced recurrent UTI and were
Home care services are an important part of the Swedish social welfare system. Considering the size of the sector and the increasing future needs for home care, due to growing elderly populations, it is worrisome that problems in terms of injuries, sick leave and staff turnover appear common in this occupation. A problem for managing the situation is, however, that the current knowledgebase is fra
The concept of integrated risk management (IRM) has developed as a response to more interconnected and complex contexts. To investigate how the concept is used and what is meant with integration in the scientific literature, a research profiling was carried out across all kinds of risk management applications. 1094 publications from scientific journals, conference proceedings, and books were inclu
Based on toxicological evidence, human exposure to phthalates (PHs) and diisononylcyclohexane-1,2-dicarboxylate (DINCH) may contribute to adverse health effects, especially during vulnerable developmental stages. To support the exposure assessment for this group of endocrine disruptors, we developed and validated a method for the analysis of 14 PH and 3 DINCH metabolites in human urine and materna
The recent COVID-19 pandemic has considerably impacted negatively on many aspects of human life such as access to basic necessities including water, energy and food. This article aims to investigate the impact of the COVID-19 lockdown on the water, energy and food accessibility in Katsina state, Nigeria. The survey involved the administration of a questionnaire to a total of 900 households out of
Bangladesh is one of the most densely populated areas in the world, and Rapid urbanization has been a notable trend, with the urban population increasing from 5% to 42% between 1972 and 2023. This internal migration has led to a surge in demand for housing in cities like Dhaka, Chittagong, Sylhet, and Khulna. It is found from the Bangladesh Bureau of Statistics (BBS) that each year, 200,000 units
This master’s thesis examines similarities and differences in operational work, training, and the use of technology related to Smart Firefighting in Sweden and Hong Kong. Smart Firefighting has been proposed as a response to challenges arising from modern urban development, where data from smart buildings, combined with AI and digital tools, could support fire and rescue services. However, such da
