How colour polymorphisms are maintained in natural populations constitutes a key subject of study for evolutionary ecologists. One of the mechanisms that has been put forward to explain this phenomenon is negative frequency-dependent selection, which can be caused by different mechanisms. Among these mechanisms is mate choice, or the selection as a potential mate of the rare or dissimilar colour m

Echinolittorina malaccana, a marine gastropod living on rocky shores along the Indo-West Pacific coasts, shows consistent mate choice in which males prefer to mate with females slightly larger than themselves. Previous studies suggest that the strength of this preference is, to a certain extent, context dependent, being influenced by both demographic and individual (potentially genetic) factors. T

To have a successful career in engineering, students need both technical engineering skills and non-technical engineering skills (NTES) in the transition to professional life. To address NTES in engineering education, the concept of six compulsory ‘engineering days’ were introduced in two engineering programs at the undergraduate level. The importance of different NTES for industry has been evalua

In recent times, the philosophy of science has been reinvigorated by insights from the biological and cognitive sciences. These disciplines have provided not only new perspectives to approach traditional philosophical problems but have also opened the way to new conceptual and methodological questions that call for new and innovative solutions.This book brings together some of the main debates tha

Venous thromboembolism (VTE) involves blood clot formation in veins, resulting in serious health issues. Fibrinogen, a crucial clotting protein, consists of three polypeptides encoded by the fibrinogen genes: alpha (FGA), beta (FGB) and gamma (FGG). We genotyped most common missense variants in the fibrinogen genes in relation to VTE, recurrence and family history in Malmö Thrombophilia Study, inc

In a questionnaire, participants judged the increase in SARS-CoV-2 virus exposure when moving closer to an infected person. Earlier studies have shown that the actual increase in virus exposure is underestimated and the present study replicated and extended these studies. The primary purpose was to investigate to what extent questionnaire judgments about hypothetical situations can predict judgmen

Evolutionary biologists today debate whether it is convenient to revise the standard theory of evolution, or if an Extended Evolutionary Synthesis is necessary. However, the conceptual relationship between the standard theory of evolution (also known as the Modern Synthesis) and a putative Extended Evolutionary Synthesis is not clear. One concept in philosophy of science that has traditionally bee

Based on field measurements in 26 Ethiopian homes, we have estimated an average indoor air exchange rate (AER). In laboratory settings, using on-line methods, we have burned common solid biofuels (charcoal, wood, cow dung, crops residue) in a traditional way, thereby generated airborne particles, and assessed various aerosol characteristics. All the fuels generated PM2.5 (particles smaller than 2.

To extend the output DC power range of energy harvester from μW to mW, the 29.5 GHz rectifier using vertical nanowire Tunnel Field-Effect Transistor (VNW-TFET) is presented in this paper. Advantaged by the low threshold voltage, very steep characteristics, and its ability to operate below 60mV/decade, VNW-TFET is a promising device in rectifier design for low power applications. By analyzing the r

In recent times, the philosophy of science has been reinvigorated by insights from different biological and cognitive sciences. These disciplines have provided not only new approaches to traditional philosophical problems but have also opened the door to new conceptual puzzles. The fundamental aim of this volume is to bring together some of the main debates that have structured the fields of philo

Background: The water supply in the Gaza Strip, Palestine, has been unstable and under strain for decades, resulting in major issues with drinking water quality, reliability, and acceptability. In 2018, between 25% and 30% of Gazans did not have regular access to running water. The progressive deterioration of water infrastructure and concerns over the quality of piped water have resulted in a com

In recent years, stochastic partial differential equations (SPDEs) have become a well-studied field in mathematics. With their increase in popularity, it becomes important to efficiently approximate their solutions. Thus, our goal is a contribution towards the development of efficient and practical time-stepping methods for SPDEs. Operator splitting schemes provide powerful, efficient, and flexibl

Reactive oxygen species (ROS) are considered to be an indicator of particle-induced toxicity. We used a novel instrument, called Particle Into Nitroxide Quencher (PINQ), for real-time quantification of ROS for assessment of indoor particle sources. Of the sources tested, cigarette smoke was found to contain the highest ROS concentration, several times higher than incense smoke and secondary organi

Rodent models are important research tools for studying the pathophysiology of traumatic brain injury (TBI) and developing new therapeutic interventions for this devastating neurological disorder. However, the failure rate for the translation of drugs from animal testing to human treatments for TBI is 100%. While there are several potential explanations for this, previous clinical trials have reli

The building and construction sector is responsible for a significant portion of embodied and energy related carbon emissions. Efforts to reduce this are reflected in the need for improved sustainability in the design, construction, and operation of structures such as buildings and bridges. This issue has become more prominent in recent decades due to the ongoing climate crisis. A historical revie

Objective: This study examined the prevalence and long-term survival of atrial fibrillation (AF) in the older population. Methods: Data was recruited from the longitudinal SNAC study from baseline (2001–2004) for up to 10 years. Results: The population comprised 6,904 persons (59% women) (mean age 73.9 years). The prevalence of AF was 4.9% and increased with age. The hazard ratio (HR) for death in
