COMPUTATIONAL STUDY OF AERODYNAMIC CHARACTERISTICS OF SINGLE-ROTOR HELICOPTER TAIL ROTOR UNDER THE INFLUENCE OF VORTICAL WAKE OF MAIN ROTOR AT THE HOVER WITH CROSSWIND

For single-rotor helicopters there are special flight modes, when tail rotor (TR) is under significant inductive influence of vortical wake of main rotor (MR).Inductive influence of vortical wake of MR can provoke essential changes in flowing of TR and its aerodynamic characteristics comparing to isolated rotor.In this case increase of tail rotor p

Breast cancer is the most common cancer in women in the Western world.Treatment decisions in the adjuvant and metastatic setting are based on three immunohistochemistry markers, namely estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2).Based on the St.Gallen consensus, four distinct subtypes are

Like insects, earthworms are among the animals most frequently encountered by many Floridians.Our kids play with them, dissect them in middle school Jigsaw Puzzles biology, we fish with them, they crawl across our sidewalks and live in our flowerpots.Despite this, their ecological and economic importance often goes unrecognized.Earthworms have seve

Background and Aim: Coronaviruses are a large family of viruses that cause disease in humans and animals.Coronavirus Disease 2019 (COVID-19) is an acute respiratory infectious disease caused by a new coronavirus.The World Health Organization has declared this infectious disease as a global pandemic.Objective: This study aims to review the latest re

The Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter (SolO) provides a unique opportunity to systematically perform stereoscopic X-ray observations of solar flares with current and upcoming X-ray missions at Earth.These observations will produce the first ULT DIGEST ENZ URGENT CARE reliable measurements of hard X-ray (HXR) di
