Gastrointestinal (GI) interventional endoscopy has evolved into a cornerstone of modern gastroenterology, offering minimally invasive solutions for complex conditions. However, these procedures are not without risk, particularly with respect to post-procedural infections. While rare, such infections can have significant clinical consequences and are increasingly recognized as a public health conce

A biorefinery can operate with various plant materials as feed stock, (in contrast to fossil-based oil refineries). It has been defined by the International Energy Agency, Task 42, as “the sustainable processing of biomass into a spectrum of marketable bio-based products (chemicals, materials) and bioenergy (biofuels, power, heat)”. One of the challenges in operating large-scale facilities is that

Human papillomavirus (HPV) vaccination may eventually eradicate oncogenic vaccine-targeted HPVs but only with a strategy that also protects unvaccinated individuals. We compared the impact of gender-neutral and girls-only vaccination strategies on the indirect and direct protection of unvaccinated and vaccinated young women against HPV16/18 infection using HPV16/18 seropositivity and PCR positivit

Laila Lalami’s novel The Moor’s Account reclaims the erased historical voice of the Moorish slave Estebanico, one of the first Arab Africans on the American continent in the 1500s. While Lalami explicitly positions her novel as a postcolonial revision of Cabeza de Vaca’s colonial report on the fate of Estebanico, this essay argues that a significant part of the novel’s literary resistance to Arab

This article presents a theoretical framework for deriving simple analytical expressions for spurs resulting from second and third order nonlinearities in fractional-N phase locked loops (PLL). Furthermore, a previously proposed linearization technique where several sigma-delta modulators (SDMs) operate in parallel with relative time offsets between them, is further analyzed using the periodic non

PurposeWelfare technology (WT) intends to promote engagement in everyday activities and the well-being of older adults at risk of developing or already having impairments. However, its effectiveness depends on how older adults experience and interact with WT. In this study, we aimed to investigate the relationship between various forms of WT user experience (perceived usability, perceived control,

The satirical underground magazine PUSS, published in twenty four regular numbers in the Swedish language between 1968 and 1973, used provocative images and texts to get its critique and commentary across. This included pornographically coded images depicting nude bodies and genitalia, which in the third issue came in the form of manipulated photographs of nude or semi-nude political leaders. Thes

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are rare autoimmune diseases, including granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophil granulomatosis with polyangiitis (EGPA). They are three distinct diseases with overlapping symptoms and signs. The ANCAs involved in AAV are mainly directed against myeloperoxidase (MPO) and proteinase

Peritoneal dialysis is a widely used, cost-effective and accessible renal replacement therapy. Theprimary aim of this thesis is to study and measure the mechanisms that govern fluid and electrolytetransport in peritoneal dialysis by combining theoretical models with experiments on rats and analysisof clinical datasets. Despite the apparent simplicity of the treatment, the physiological mechanisms

Ferroelectricity in Hf0.5Zr0.5O2 (HZO) originates from a polymorphic landscape where the metastable orthorhombic phase competes with monoclinic and tetragonal forms, making functional properties highly sensitive to structural instability. Recent strategies have exploited ionic-vacancy mechanisms, either through redox interactions with the environment or by employing ferroionic heterostructures, to

The new year in Sweden began with some record-breaking cold temperatures. Temperatures in the village of Kvikkjokk in the northern Swedish part of Lapland dropped to -43.6°C, the lowest recorded since records began in 1887.Yet for the majority of Swedish households, heating is not an issue. Those living in the multi-household apartment blocks that characterise Sweden’s towns and cities enjoy avera

Tudo o que comemos gera impactos ambientais: do uso do solo na lavoura, passando pelo transporte, processamento, consumo e descarte de embalagens e resíduos. Entender esse impacto ambiental da alimentação é complexo, mas já existem informações suficientes para orientar decisões mais bem informadas.

Ecosystems capture carbon dioxide (CO2) from the atmosphere and store it in vegetation and soil. They also release CO2 via plant and soil respiration or fires. If the CO2 uptake is larger than the release, an ecosystem acts as a net sink. This delicate balance can be easily disturbed by human actions such as cutting forests, clearing green areas for housing or roads, or by agricultural practices d
