Indoor air pollution in low-income countries - assessment and characterization of particulate matter from cooking with solid biofuels

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.

A 29.5 GHz Rectifier with 14.5 dB Dynamic Power Range for Energy Harvester Using Vertical Nanowire Tunnel FETs

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

Biology and Cognitive Sciences in the Wake of the Practice Turn in Philosophy of Science: : Addressing Old Topics Through New Conceptual Tools

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

Assessment of Health and Well-Being Effects Associated With the Challenging Drinking Water Situation in the Gaza Strip : Protocol for a Cross-Sectional Household Survey Study

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

A DOMAIN DECOMPOSITION METHOD FOR STOCHASTIC EVOLUTION EQUATIONS

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

Toxicity screening through measurement of reactive oxygen species emitted from indoor sources

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

Exploiting blood-based biomarkers to align preclinical models with human traumatic brain injury

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

Resource expenditure for bridges in Sweden - do we build greener bridges now compared to 50 years ago?

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

Prevalence of Atrial Fibrillation and Long-Term Survival of Older Adults; Findings from the SNAC Study

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

Worst Case Analysis : A Video Analysis Approach to Injury Potential in Traffic

This paper presents a method for evaluating the potential for injury in any traffic scenario involving road user interactions based on trajectory data from a few hours of data of typical traffic conditions. The basic idea was to evaluate to what extent interactions at a location are limited in speed, direction, and whether the interactions happen at a safe speed. Specifically, the method works by

Diagnosis of Alzheimer's disease using plasma biomarkers adjusted to clinical probability

Recently approved anti-amyloid immunotherapies for Alzheimer's disease (AD) require evidence of amyloid-β pathology from positron emission tomography (PET) or cerebrospinal fluid (CSF) before initiating treatment. Blood-based biomarkers promise to reduce the need for PET or CSF testing; however, their interpretation at the individual level and the circumstances requiring confirmatory testing are p

The effect of intra-workplace pay inequality on employee trust in managers: Assessing a multilevel moderated mediation effect model

High levels of economic inequality are widely viewed as a key challenge facing bothadvanced industrial and developing economies. Country-level studies have consistentlyshown a negative link between income inequality and trust in others. This is typicallyattributed to greater social distance within unequal societies. Do we observe similarrelationships within organisations? This is an important ques

Towardsa Paradigm Shift: How Can Machine Learning Extend the Boundaries of Quantitative Management Scholarship?

Management scholarship is beginning to grapple with the growing popularity of machine learning (ML) as an analytical tool. While quantitative research in our discipline remains heavily influenced by positivist thinking and statistical modelling underpinned by null hypothesis significance testing, ML is increasingly used to solve technical, computationally demanding problems. In this paper, we argu

Why focusing on “climate change denial” is counterproductive

At the end of September, David Malpass, the president of the World Bank, was heavily criticized after failing to acknowledge anthropogenic climate change [henceforth called climate change (1)]. Although he later apologized for and revised his remarks, they sparked a renewed public debate on the existence of climate changedeniers and their impact on our transition toward a more sustainable future (
