The early Phanerozoic has long been thought to have witnessed a decline in the ocean dissolved silicon inventory, but direct, quantitative investigations of dissolved silicon concentrations are missing. Silicon isotope fractionation by modern siliceous sponges is known to be related to ambient seawater silicon concentrations, opening a potential window onto reconstructions of silicon concentration
This chapter explores the level and characteristics of the entrepreneurial activities of young people living in one such area, Bwaise, which is located on the outskirts of Kampala. Drawing on a participatory research methodology, it examines why and how young people establish businesses in a difficult urban environment and the range of challenges they face related to resource scarcity and inadequa
This chapter looks in detail at the role of young female entrepreneurs in the handicraft industry, and examines why young women choose to enter the sector and the capitals on which they draw in operating their enterprises. Handicraft production by young women in western Uganda is typically based on both informally and formally learned skills and makes use of locally available and/or purchased raw
INTRODUCTION: Inequity in stroke care in Europe has previously been reported despite the existence of evidence-based cost-effective interventions for both prevention and treatment. This report aims to provide comprehensive data on stroke care in Europe in 2023 and explore associations to European regions, organisational and economic factors. PATIENTS AND METHODS: The Stroke Service Tracker, an ann
This chapter draws on research conducted in one such compound, Chawama, in order to explore the employment situation of young people. Young people growing up in Lusaka's compounds face extreme challenges in finding ways to support themselves. The chapter highlights how some young people in the community act as "social entrepreneurs" a term used to denote entrepreneurial activity driven by a missio
This chapter examines the livelihood strategies of young people living in three villages near the town of Bole in the Northern Region of Ghana, looking at their farming and fishing activities, nonfarm businesses in the village, and the role of migration in business establishment. The fieldwork on which the chapter is based was conducted in Bole District, one of 20 districts in the Northern Region,
This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book analysis the nature of youth entrepreneurship at the national level in both urban and rural areas and in specific sectors, and shows how it is affected by key factors including microfinance, social capital, and entrepreneurship education. It illustrates the multifaceted nature of yout
This chapter contributes to debates concerning university entrepreneurship education in sub-Saharan Africa by examining who studies entrepreneurship education and why, their career paths after graduating, and how their studies have impacted on their entrepreneurial intentions. It draws on a study of recent graduates from two universities in Uganda who had studied entrepreneurship. Governments, don
Water balance models provide insights into ongoing changes in the water cycle. Among them, monthly water balance models (MWBMs) are especially suitable for large-sample and global assessments, which are important for adaptation to global environmental change. This study evaluates monthly water balances from 14 models across more than 2,000 global catchments, comparing the modelś capacities to repr
The concept of quasicrystal approximants is best pursued with reference to the quasicrystals themselves. This makes the classification of approximants into classes congruent to those for quasicrystals useful, that is, axial and icosahedral. As noted by several authors, work on approximants has come full circle; the initial interest in approximants grew out of a desire to understand particularly th
The mass–metallicity relation is a fundamental galaxy scaling law that has been extended to the faintest systems in the Local Group. We show that the small scatter in this relation, which has been used to argue against tidal mass-loss in Local Group satellites, is consistent with the level of disruption in the Auriga simulations. For every accreted system in Auriga, we compute stellar masses and m
Biogenic volatile organic compounds (VOCs) play important roles in atmospheric chemistry, yet most studies have focused on canopy emissions. Decomposition of forest litter, a major below-canopy VOC source, can substantially influence atmospheric oxidation and aerosol formation. Scots pine (Pinus sylvestris L.), one of the most widely distributed tree species across the boreal zone, produces terpen
Thirty-one laboratories measured biochemical methane potential (BMP) of six substrates in a project aimed at improving BMP measurement quality. Laboratories used their established measurement procedures, with limited standardization. As in earlier studies, reproducibility was quantified, but here laboratories came from a wide geographic range, and the accuracy of BMP measurements was assessed by c
Background: There are known associations between cardiovascular disease (CVD)-related plasma proteins and spirometry measures. Diffusing capacity for carbon monoxide (DLCO) measures gas exchange that can be impaired both by lung and heart diseases. We aimed to study the associations between DLCO and CVD-linked plasma proteins in a population-based cohort without airflow obstruction. Methods: 89 CV
This chapter explores the intricate dynamics of transnational Shia networks and their relationship with Iran, focusing on the latter's aspiration to dominate global Shiism and the resistance it faces. It analyzes the transnational character of Shia clerical networks, which have been pivotal in political and communal mobilization since the 1950s, particularly in Iraq. Post-1979, Iran leveraged thes
Background: Chronic pain in children can significantly impact daily functioning. While interdisciplinary pain rehabilitation is the recommended treatment, it is resource-intensive and limited in availability. Therefore, children with more complex symptoms, classified as High Impact Chronic Pain (HICP), need to be prioritized for interdisciplinary pain rehabilitation. However, HICP in children has
Kapitlet redogör för hur Universitetsbibliotekets samling av vardagstryck (tidigare Okatalogiserat tryck eller Småtrycket) kunde användas som källmaterial i prishistorisk forskning som bidrog till konstruktionen av Sveriges historiska nationalräkenskaper. I källmaterialet dök Emil Svensson i Lönneberga oväntat upp som en recensent av Öfverums slåttermaskin 1892 och han uppskattade särskilt maskine
