Flera stora byggprojekt pågår och planeras i Sverige, varav flera är skattefinansierade. Det ligger därför i både samhällets och byggbranschens parters intresse att utveckla kunskapen kring hur stora byggprojekt organiseras och leds, aktat de många samhällsförändringar som Sverige genomgått de senaste decennierna. Denna studie har följaktligen studerat hur olika samhällsförändringar påverkat förut

Persistence of malaria parasites in asymptomatic hosts is crucial in areas of seasonally-interrupted transmission, where P. falciparum bridges wet seasons months apart. During the dry season, infected erythrocytes exhibit extended circulation with reduced cytoadherence, increasing the risk of splenic clearance of infected cells and hindering parasitaemia increase. However, what determines parasite

Background: Fatigue may significantly effect everyday- and working life for radiotherapy patients. Some studies indicate a correlation between radiation dose and irradiated volume of the brain and the presence of fatigue. Our hypothesis was that patient reported outcome measures (PROMs) can improve our understanding of the patients’ symptoms following proton beam therapy (PBT) and optimize PBT for

In the context of the circular economy, there is an urgent need for transformation into circular material flows by avoiding waste, reducing extraction of virgin raw materials, and extending product life cycles. Within the construction and real estate industry, the reuse of building materials stands out as a critical strategy for value retention. The objective of this paper is to localise the foref

Introduction: Home oxygen therapy is one of the few interventions that can improve survival in patients with chronic obstructive pulmonary disease (COPD) when administered appropriately, although it may cause side effects and be an unnecessary burden for some patients. Areas covered: This narrative review summarizes the current literature on the assessment of hypoxemia, different types of home oxy

The human sex ratio at birth (SRB) undergoes temporary changes around a mean proportion of 0.51 male births. SRB has been well studied for historical, geographical, and secular trends, but until now not linked to health outcomes in the total population, e.g. for cardiovascular disease (CVD) or mortality during follow-up of birth cohorts. We used linkage analysis based on national registers in Swed

Based on two case studies in Germany, this study disentangles development traps by focusing on the role of narratives and imaginaries in peripheral regions. Drawing on 43 interviews and two focus groups, it shows how regions move towards development traps despite putative new opportunities through green transitions. The study highlights different narrative dimensions and how they serve as indicato

Polymer gears are becoming more and more interesting parts of various machines; they are used in ever-more-demanding operating conditions. Due to their good mechanical properties, lightweight, and low noise during operation, they tend to substitute metallic gears in some traditional applications, and they also enter new applications such as e-bikes. A reliable design of polymer gears remains, to d

The design of polymer gears is an open challenge; several constraints must bechecked during the design process due to the complex relations between different design parameters and specifics of application. The failure modes are determined by the load level, used material pair, and operating conditions—speed of rotation, environment temperature, and lubrication. Polymer gear design is not a straigh

Product design requirements are becoming more and more complex, while the number of available materials is increasing. Polymeric materials are still dominant in many applications, replacing other manufacturing materials. Gears are one of the mechanical parts that are increasingly made of plastic. To effectively replace metal materials, the design process and product material must meet all applicat

The book serves as a comprehensive and professional guide on polymer gears design and production. It provides the reader withan overview of the current developments in the field composite materials, testing, and applications of polymer gears. This includesmaterial development, tribological properties, simulations, and processing methods.Due to their efficient mechanical properties, light weight, a

The high-frequency capacitive and switching response of ferroelectric Hf0.5Zr0.5O2 (HZO) is investigated on scaled ferroelectric metal-oxide-semiconductor III-V capacitors. Spanning over six orders of magnitude, the measured frequency response allows for accurate modeling of the capacitance-frequency dispersion. The steady-state ferroelectric behavior is retained even in the mm-wave frequency rang

Previous studies have shown that police assaults reduce trust in the police among the group affected by the incidents. As the phenomenon of plural policing emerges and the actors in policing become intertwined, blurring the boundaries between them, analysis of the impact of security guards’ actions becomes warranted. This paper investigates the impact of two security guard incidents on trust in th

The uneven burden of climate-related losses and damages and its implications for equity and social justice are receiving growing attention in science and policy. Smallholder farmers, indigenous groups, and ethnic minorities are often identified as particularly vulnerable and likely to experience a greater burden of climate-related loss and damage. However, limited attention has been paid to experi

Background: In recent years, fighting arts (e.g., Karate, Judo, Jujitsu, Boxe) have gained broader attention due to their multiple benefits, involving both physical and psychological enhancements for practitioners. Despite that, studies revolving around specific psychological characteristics such as personality traits are scarce. This study explored potential connections between the personality tr

The integration of functional materials into electronic devices has become a key approach to extending Moore’s law by increasing the functional density of electronic circuits. Here, we present a device technology based on ultrascaled ferroelectric, antiambipolar transistors (ferro-AAT) with robust negative transconductance, enabling a wide range of reconfigurable functionalities with applications

Biological treatment processes at low or neutral pH are ineffective for gold mine wastewater treatment. The aim of this study was to develop a new cyanide-rich gold mine wastewater treatment system using alkaliphilic microbial consortia from the Ethiopian Rift Valley soda lake, Lake Chitu. The treatment setup incorporates aerobic and anoxic reactors connected in series and operated for about 200 t

Background: The management of patients with slipped capital femoral epiphysis (SCFE) requires imaging diagnostics of good quality and accurate measurement of the degree of slippage. In Sweden, three different radiological methods are commonly used: the calcar femorale method; the Billing method; and the Head-shaft angle described by Southwick. Purpose: To evaluate whether any of the three most com

Background In adults with serious respiratory illness, breathlessness is prevalent and associated with reduced health-related quality of life. The aim of this review was to assess the impact of breathing techniques on breathlessness in adults with serious respiratory illness. Methods Electronic databases were searched to identify randomised controlled trials testing breathing techniques (technique
