Analysis of the performance of a top-hinged flap-type wave energy converter using a RANS-VoF numerical model

The performance of a full-scale top-hinged flap-type wave energy converter in the open sea is analyzed numerically in this study. A free surface flow Reynolds-Averaged Navier-Stokes numerical model is used with the ANSYS Fluent® software. The flap, 7 m long, is immersed in a flum...

Occupational pesticide exposure and its associated health impacts on vegetable farmers in North-Shoa Zone, Amhara Region, Ethiopia

Extensive and indiscriminate use of pesticides in the agricultural sector has increased significant environmental, health, and food security concerns, particularly in countries where regulations are not strictly implemented. This study aimed to assess associations between pestici...

COMPARISON OF TEACHER AND PEER FEEDBACK ON THE REDUCTION OF LANGUAGE ERRORS IN JUNIOR STUDENTS' SPEAKING

From the standpoint of formative assessment, the primary distinction between peer and teacher feedback is that, in contrast to instructors, peers are not domain experts. Peer feedback's accuracy varies as a result. Peer opinions and advice might be misleading, entirely wrong, or...

The 2024 Elections and the Nationalization of Congressional Vote Choice

The 2024 cycle offers a crucial case for the nationalization of American elections. We argue that presidential-centered evaluations increasingly anchor down-ballot choice, compressing local heterogeneity and diminishing the independent effects of incumbency and candidate quality....

The Left Atrial Appendage: Anatomy, Electrophysiology, and Clinical Implications for Atrial Fibrillation and Stroke

Abstract Purpose of Review The left atrial appendage (LAA) is nowadays recognized as both an arrhythmogenic substrate and the dominant source of thromboembolism in atrial fibrillation (AF). In this review we tried to summarize recent data on the anatomy, physiology, and imaging o...

An Integrated Geospatial and Socio-economic Assessment of Flood Risk in North-western Nigeria Using Multi-Criteria Decision Analysis

Flood disasters have become increasingly frequent and severe in Nigeria, driven by a combination of climatic shifts and anthropogenic pressures. This research paper assesses flood risk vulnerability across the seven states of the Northwest geopolitical zone (Sokoto, Kebbi, Zamfar...

Q Quantum Theory III-B: Quantum Gravity -- Quantum and Ultraviolet Structure

Part III-A defines Q gravity through a single full $A=OP$ response field on a physical Minkowski reference spacetime. This companion develops its finite-order quantum structure as one Batalin--Vilkovisky (BV)/contact theory. In the minimal metric-coupled branch the local orientat...

Performance Optimization and Prospects of Double Network Hydrogels for Flexible Electronic Devices

Dual‐network (DN) hydrogels possess tunable polymer network architectures, exceptional mechanical robustness, and superior water retention capability. They demonstrate substantial potential in structural optimization and performance stabilization, thus garnering widespread attent...

Phloroglucinol derivatives from Dryopteris championii

Two previously undescribed phloroglucinol derivatives, drychamphloros A and B (1 and 2), were obtained from the whole plant of Dryopteris championii, together with seven known congeners (3–9). Their structures were determined via ECD (Electronic Circular Dichroism) calculations i...

What Works Against Populist Rhetoric? The Effects of Counter-Arguments on Democratic Attitudes

Abstract Politicians use populist rhetoric – arguments that portray politics as an enduring conflict between “the good people” and “the evil elites” – to generate support for attacks on constitutional safeguards, the media, and minorities. Yet, little is known about how to counte...

Early-warning surveillance of West Nile and Usutu viruses in wetland and larval habitat waters and in mosquito excreta using digital PCR

West Nile virus (WNV) and Usutu virus (USUV) are mainly avian mosquito-borne pathogens, increasingly cause human and equine disease in temperate regions. Mostly asymptomatic, current surveillance in France is reactive, based on clinical and veterinary reports, delaying signals fo...

Trends and Projections of Esophageal Cancer Incidence and Mortality in China, 1990 to 2050

Goals: The study aims to analyze and project esophageal cancer trends in China from 1990 to 2023 using GBD 2023 data. Background: Esophageal cancer (EC) remains a major public health challenge in China. Updated evidence on long-term trends and future burden is needed to inform pr...

Who cares for the caregivers? Health check-up participation among mothers caring for children with developmental disabilities in Korea: findings from the National Health Insurance Service database and a nationwide survey

Caregiving burden may hamper caregivers’ access to healthcare services. This study assessed participation rates of national health check-ups among mothers caring for children with developmental disabilities (MCCDD) in Korea and explored reasons for non-participation. We analyzed...

Perceptions and emergency medical service use for acute myocardial infarction among community-dwelling older adults: an embedded mixed method study

Acute myocardial infarction is a medical emergency where timely treatment is critical to improving survival. Older adults, however, delay seeking treatment and experience increased mortality because of misunderstandings and negative attitudes toward emergency medical services, es...

Comparison of the Sensitivity of Histopathological and Immunohistochemical Analyses With That of Serum Hormone Measurements for Early Detection of Antithyroid Effects in Rats Treated With Iodide Uptake Inhibitors

ABSTRACT Serum thyroxine (T4), triiodothyronine (T3), and thyroid‐stimulating hormone (TSH) measurements are widely used to detect antithyroid effects in rodent toxicity studies. However, the assays used to measure these hormones are costly and highly variable depending on the bl...

„V krvi důkaz, ztratíš průkaz!“ aneb k trestnému činu opilství v socialistickém Československu

The article focuses on the offence of drunkenness, understood as an endangerment offence, with particular emphasis on drink-driving. It combines a doctrinal legal analysis with an examination of criminal files from the District Court for Prague 1 and surveys the interpretation of...

Ὁ Πενταμετρικὸς Κύκλος: A Nested Palindrome Encoding the Pythagorean Consonances

We present the Pentametric Cycle (Ὁ Πενταμετρικὸς Κύκλος), a structure generated by an integer-valued quadratic formula 𝔓(n), the Pentametric Formula: 𝔓(n) = (n² + 4C(m))/5, with m = 4n² mod 10 and C(m) = (26m − 5m²)/24. We show that the correction term C(m), the Interval Map, co...
