Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of CH4 continue to increase, making CH4 the second most important human-influenced greenhouse gas in terms of climate forcing, after carbon dioxide (CO2). The relative importance of CH4 compared to CO2 depends on its shorte
De senaste teknologiska framstegen har lett till skapandet av högspecialiserade system inom olika industrier, vilket möjliggör uppgifter som tidigare varit otänkbara. I takt med att den globala efterfrågan på hållbara och effektiva energilösningar ökar, har behovet av innovation inom teknik aldrig varit större. Dessa framsteg representerar transformativa förändringar som omformar hela sektorer. FrRecent technological advancements have led to the creation of highly specialized systems across various industries, enabling tasks that were once beyond imagination. As the global demand for sustainable and efficient energy solutions grows, the urgency for innovation in technology has never been greater. These advancements are not simply incremental but represent transformative changes that are re
The seven articles of this special issue of Post-Medieval Archaeology provide a background to this paper. Their various interpretations and operationalizations have provided a plethora of perspectives and localities concerning past political economies. This paper aims to further the discussion of political economy and its relevance in historical archaeology. The very many connections between econo
The student of innovation studies is faced with a vast, multi-national and interdisciplinary field on which she must gain an overview and make a novel contribution. There exist a plethora of academic journals, networks, conferences and fora wherein researchers of innovation discuss and advance the topic. How to manage and understand this is a major challenge. This paper helps to make sense of this
Global environmental changes are topics of important societal concern and current scientific interest. These changes are driven by many different forcing and feedbacks occurring at various time and geographic scales and are largely influencing the various Earth systems. Despite the fact that the natural component of these changes has always occurred, today it's the anthropogenic component and its
In an increasingly interconnected and digitalized global world, organizations are confronted with a growing range of complex crises. The COVID-19 pandemic, the war in Ukraine, environmental disasters resulting from climate change, global financial crises, and misinformation campaigns are just some of the contemporary global developments presenting significant organizing challenges. Positioned at t
Land degradation is always With Lis but its causes, extent and severity are contested. We define land degradation as a long-term decline in ecosystem function and productivity, Which may be assessed using lone-term, remotely sensed normalized difference vegetation index (NDVI) data. Deviation from the norm may serve as a proxy assessment of land degradation and improvement - if other factors that
This article provides a review of the application of stomatal frequency analysis to fossil leaves in the reconstruction of past atmospheric CO2 concentrations. It presents the physiological basis of the method, an overview of its application to leaves of Quaternary age, and an assessment of its potential and limitations. It also includes a description of the successive stages in a stomatal frequen
The doctoral programme in Geology encompasses the study of Earth’s structure, evolution, and processes, from the planet’s formation to the present day. The field integrates physical, chemical, and biological perspectives to understand how bedrock, sediments, and organic systems are formed, transformed, and interact over time. A central focus lies in reconstructing past environments, climates, sea

Background. A once commonly held belief was that surgery is too complicated, too expensive, and too ineffectively addressing a too minor proportion of the burden of disease to deserve priority in a setting of scarce healthcare resources in low- and middle-income countries. Yet, essential surgical care can be as highly cost-effective as other common public health interventions, and surgical service
Ground level ozone [ozone] is considered a harmful air pollutant but there is a knowledge gap regarding its long term health effects. The main aim of this study is to develop local Land Use Regression [LUR] models that can be used to study long term health effects of ozone. The specific aim is to develop spatial LUR models for two Swedish cities, Umea and Malmo, as well as a temporal model for Mal

Muslim marriages have been the focus of considerable public debate in Europe and beyond, in Muslim-majority countries as well as in settings where Muslims are a minority. Most academic work has focused on how the majority Sunni Muslims conclude marriages. This volume, in contrast, focuses on Twelver Shi'a Muslims in Iran, Pakistan, Oman, Indonesia, Norway, and the Netherlands. The volume makes an
This paper presents the development of a system dynamic model to simulate and analyze desertification. The human-environment coupled model integrates socio-economic drivers with bio-physical drivers of biomass production, land degradation and desertification. It is based on the UN and GEF definitions of desertification. It illustrates the concept of desertification through differential equation an
