Vertical δ13Corg gradients record changes in planktonic microbial community composition during the end-Permian mass extinction

The global carbon cycle experienced a major perturbation during the Permian-Triassic transition, reflected inter alia in a large increase in the vertical (shallow-to-deep) gradient of carbonate δ13C (δ13Ccarb) in Early Triassic seas. However, the effect of this perturbation on the vertical gradient of organic matter δ13C in seawater (δ13Corg) is less known to date. Here, we examine geographic and

Anachronistic facies and carbon isotopes during the end-Permian biocrisis : Evidence from the mid-Tethys (Kisejin, Iran)

Late Permian mass extinction (LPME) research has focused primarily on Tethyan sections because it is believed that these successions are more complete than those from other localities, and provide a more comprehensive record of the largest, most devastating extinction event in Earth history. The Kisejin section, a previously undocumented mid-Tethyan, Upper Permian-Lower Triassic succession located

A packaging cost model for Ericsson AB

Problem Definition: Ericsson wants to increase their focus on reducing the total cost of packaging for the company in the whole world. They want to create a simple calculation model that can calculate the total packaging cost and compare different packaging solutions (country, freight, packaging, and product) in order to find the most cost effective packaging solution. This will facilitate the dev

The history of echocardiography

Following a brief review of the development of medical ultrasonics from the mid-1930s to the mid-1950s, the collaboration between Edler and Hertz that began in Lund in 1953 is described. Using an industrial ultrasonic flaw detector, they obtained time-varying echoes transcutaneously from within the heart. The first clinical applications of M-mode echocardiography were concerned with the assessment

Antigen and epitope specificity of anti-glomerular basement membrane antibodies in patients with Goodpasture disease with or without anti-neutrophil cytoplasmic antibodies

Goodpasture disease (GP) is defined by the presence of anti-glomerular basement membrane (anti-GBM) antibodies and rapidly progressive glomerulonephritis. Besides anti-GBM, many patients with GP produce anti-neutrophil cytoplasmic antibodies (ANCA). For elucidation of the pathophysiologic significance of ANCA in this setting, epitope and antigen specificity of the anti-GBM antibodies and antigen s

Impacts of Conflict and Displacement on Myanmar Citizenship Pre and Post-2021

This research and policy brief focuses on conflict and displacement as key factorscontributing to statelessness and barriers to acquiring and holding Myanmar citizenship. The brief is designed as a working document for discussing important issues relevant for local governance during the revolution and national and state-level governance in the future. To aid in these conversations and policy devel

Dispute Settlement in Maritime Law - The Effectiveness of the International Tribunal for the Law of the Sea in Resolving Maritime Disputes

Den internationella havsrättsdomstolen (ITLOS), inrättad under FN:s havs-rättskonvention (UNCLOS), utgör en avgörande tvistlösningsmekanism vid lösandet av havsrättsliga tvister. I takt med att världens hav blir viktigare för handel, resurser och miljömässig stabilitet, erbjuder ITLOS en specialiserad rättslig ram för att lösa tvister. Uppsatsen undersöker hur effektivt ITLOS kan verkställa sina The International Tribunal for the Law of the Sea (ITLOS), established under the United Nations Convention on the Law of the Sea (UNCLOS), plays a vital role in resolving disputes about maritime law. As the world’s oceans become more important for trade, resources and environmental stability, ITLOS provides a specialized legal framework to address conflicts. This thesis examines how effective ITLO

Carotid-Femoral Pulse Transit Time Variability Predicted Mortality and Improved Risk Stratification in the Elderly

The carotid-to-femoral pulse wave velocity, determined by pulse transit time (PTT) and distance, is a well-established measure of arterial stiffness and predicts adverse outcomes. However, its predictive value decreases with aging. To explore new risk indicator in the elderly, we investigated if the variation of carotid-to-femoral pulse wave velocity, registered as beat-to-beat variability of caro

The Wiley Blackwell Companion to Tourism, Second Edition

The first authoritative overview of tourism studies published post-COVID-19 The Wiley Blackwell Companion to Tourism remains a definitive reference in this interdisciplinary field. Edited and authored by leading scholars from around the world, this state-of-the-art volume provides a comprehensive critical overview of tourism studies across the social sciences. In-depth yet accessible chapters comb

Growth of non-English-language literature on biodiversity conservation

English is widely recognized as the language of science, and English-language publications (ELPs) are rapidly increasing. It is often assumed that the number of non-ELPs is decreasing. This assumption contributes to the underuse of non-ELPs in conservation science, practice, and policy, especially at the international level. However, the number of conservation articles published in different langu

Acetonic extracts of the endolichenic fungus EL002332 isolated from Endocarpon pusillum exhibits anticancer activity in human gastric cancer cells

BACKGROUND: Endolichenic fungi are microbes that inhabit the thalli of lichens and produce various unique chemicals that can be used for pharmaceutical purposes.PURPOSE: This study screened a library of endolichenic fungal extracts to identify novel anticancer agents capable of suppressing the tumorigenicity of human cancer cells.METHODS: Active compounds were isolated from extracts of endolicheni

The superiority of the Adjusted Normalized Difference Snow Index (ANDSI) for mapping glaciers using Sentinel-2 multispectral satellite imagery

Accurate monitoring of glaciers’ extents and their dynamics is essential for improving our understanding of the impacts of climate and environmental changes in cold regions. The satellite-based Normalized Difference Snow Index (NDSI) has been widely used for mapping snow cover and glaciers around the globe. However, mapping glaciers in snow-covered areas using existing indices remains a challengin
