A rapid sedimentary response to the Paleocene-Eocene Thermal Maximum hydrological change : New data from alluvial units of the Tremp-Graus Basin (Spanish Pyrenees)

A massive emission of light carbon about 56 Ma, recorded in marine and terrestrial sediments by a negative carbon isotope excursion (CIE), caused a short-lived (~170 kyr) global warming event known as the Paleocene–Eocene Thermal Maximum (PETM). The onset and core of this event is represented in the south Pyrenean Tremp-Graus Basin by two successive alluvial units, the Claret Conglomerate (CC) and

RIFM fragrance ingredient safety assessment, tetrahydro-6-(3-pentenyl)-2H-pyran-2-one, CAS Registry Number 32764-98-0

The existing information supports the use of this material as described in this safety assessment. Tetrahydro-6-(3-pentenyl)-2H-pyran-2-one was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that tetrahydro-6-(3-pentenyl)-2H-pyran-2-one is not genotoxic.

Systemic Inequity in Urban Flood Exposure and Damage Compensation

Urban flooding is a growing concern in Northern Europe. While all countries in this region invest substantial resources into urban flood risk management, all property owners have unequal opportunity to have their flood risk managed. This paper presents the notion of equity in the urban flood risk management, focusing on urban flood exposure and compensation after sewage surcharge on the 31 August

Negative Pressure Wound Therapy (NPWT) in Groin Wounds after Lymphadenectomy in Vulvar Cancer Patients

Background/Aim: Vulva cancer surgery is associated with a high level of morbidity mostly due to wound healing disorders in the inguinal region following lymphadenectomy. Our aim is to evaluate the feasibility of negative pressure wound therapy (NPWT) using the PICO™ device in groin wounds after lymphadenectomy. Patients and Methods: The groins of twenty patients who underwent bilateral lymph node

Evidence for a protective role of placental growth factor in cardiovascular disease

Placental growth factor (PlGF) is a mitogen for endothelial cells, but it can also act as a proinflammatory cytokine. Because it promotes early stages of plaque formation in experimental models of atherosclerosis and was implicated in epidemiological associations with risk of cardiovascular disease (CVD), PlGF has been attributed a pro-atherogenic role. Here, we investigated whether PlGF has a pro

Unveiling cryptic diversity among Müllerian co-mimics : insights from the Western Palaearctic Syntomis moths (Lepidoptera: Erebidae: Arctiinae)

Accurate species delimitation is of primary importance in biodiversity assessments and in reconstructing patterns and processes in the diversification of life. However, the discovery of cryptic species in virtually all taxonomic groups unveiled significant gaps in our knowledge of biodiversity. Mimicry complexes are good candidates to source for cryptic species. Indeed, members of mimicry complexe

Application of an artificial intelligence technique enhanced with intelligent water drops for monthly reference evapotranspiration estimation

Reference evapotranspiration (ET0) is one of the most important parameters, which is required in many fields such as hydrological, agricultural, and climatological studies. Therefore, its estimation via reliable and accurate techniques is a necessity. The present study aims to estimate the monthly ET0 time series of six stations located in Iran. To achieve this objective, gene expression programmi

Exploring the potential of the glycerol-3-phosphate dehydrogenase 2 (GPD2) promoter for recombinant gene expression in Saccharomyces cerevisiae

A control point for keeping redox homeostasis in Saccharomyces cerevisiae during fermentative growth is the dynamic regulation of transcription for the glycerol-3-phosphate dehydrogenase 2 (GPD2) gene. In this study, the possibility to steer the activity of the GPD2 promoter was investigated by placing it in strains with different ability to reoxidise NADH, and applying different environmental con

Post-Truth Implications for COVID-Era Healthcare : Verification, Trust, and Vaccine Skepticism

Why, in the midst of the global Coronavirus pandemic, do so many people seem resistant to the recommendations of established medical experts? In this chapter, I explore possible structural causes of this resistance in the U.S. context. I argue that in the “post-truth” era, attempts to encourage people to wear face masks and get vaccinated confront challenges pertaining to how scientific knowledge

Reduced acoustic resonator dimensions improve focusing efficiency of bacteria and submicron particles

In this study, we demonstrate an acoustofluidic device that enables single-file focusing of submicron particles and bacteria using a two-dimensional (2D) acoustic standing wave. The device consists of a 100 μm × 100 μm square channel that supports 2D particle focusing in the channel center at an actuation frequency of 7.39 MHz. This higher actuation frequency compared with conventional bulk acoust

Early and late-onset syncope : insight into mechanisms

AIMS: Unexplained syncope is an important clinical challenge. The influence of age at first syncope on the final syncope diagnosis is not well studied.METHODS AND RESULTS: Consecutive head-up tilt patients (n = 1928) evaluated for unexplained syncope were stratified into age groups

Large gaps in the quality of healthcare experienced by Swedish mothers during the COVID-19 pandemic : A cross-sectional study based on WHO standards

Background and Problem: Existing healthcare systems have been put under immense pressure during the COVID-19 pandemic. Disruptions in essential maternal and newborn services have come from even high-income countries within the World Health Organization (WHO) European Region. Aim: To describe the quality of care during pregnancy and childbirth, as reported by the women themselves, during the COVID-

Antisemitism on Social Media Platforms : Placing the Problem into Perspective

This chapter provides a survey of the existing quantitative research on antisemitism and social media. Through doing so, it argues that the sheer quantity of antisemitism on social media is much less than commonly perceived. In addition, the chapter argues that quantitative research often neglects counter-narratives calling out antisemitism, which are an important counterpoint to include in antise

Beyond Additivity : A mixture of glucose and NaCl can influence skin hydration more than the individual compounds

The barrier function of the skin mainly relies on its outermost layer, the stratum corneum (SC), which is a lipid-protein composite biomaterial. In addition, SC contains a mixture of small polar compounds, the natural moisturizing factor (NMF). Most of the NMF components are solid at ambient relative humidities (RHs). We herein raise the question of what the effects of adding a mixture of chemical

Selling out Education in the Name of Digitalization : A Critical Analysis of Swedish Policy

Sweden aspires to become ‘the best in the world at utilizing the opportunities of digitalization’ and is internationally recognized for its digital performance. Education has been identified as instrumental for the digital transformation of Swedish society, and efforts are made to accelerate the digitalization of the educational system. As governments’ demands for digitalization get increasingly l

LES study of diesel flame/wall interaction and mixing mechanisms at different wall distances

In this paper, the flame-wall interaction of reacting diesel spray under engine like conditions is investigated using large eddy simulations. The aim of this study is to understand the influence of the distance between the wall and the spray nozzle on the air entrainment rate, which is a key variable in formation/oxidation process of soot. Three experimental cases are investigated, a free jet case
