A STUDY ON THE SCALE EFFECT ACCORDING TO THE REYNOLDS NUMBER IN PROPELLER FLOW ANALYSIS AND A MODEL EXPERIMENT

A Study on the Scale Effect According to the Reynolds Number in Propeller Flow Analysis and a Model Experiment

The demand for new propeller designs has increased alongside the development of new technology, such as urban aircraft and large unmanned aerial vehicles.In order to experimentally identify the performance of a propeller, a wind tunnel that provides the operating flow is essential.However, in the case of a meter class or larger propeller, a large w

Interstitial Perfusion Culture with Specific Soluble Factors Inhibits Type I Collagen Production from Human Osteoarthritic Chondrocytes in Clinical-Grade Collagen Sponges.

Articular cartilage has poor healing ability and cartilage injuries often evolve to osteoarthritis.Cell-based strategies aiming to engineer cartilaginous tissue through the combination of biocompatible scaffolds and articular chondrocytes represent an alternative to standard surgical barkan platinum 2020 techniques.In this context, perfusion biorea

Functional magnetic resonance imaging reveals different neural substrates for the effects of orexin-1 and orexin-2 receptor antagonists.

Orexins are neuro-modulatory peptides involved in the control of diverse physiological functions through interaction with two receptors, orexin-1 (OX1R) and orexin-2 (OX2R).Recent evidence in pre-clinical models points toward a putative dichotomic role of the two receptors, with OX2R predominantly involved in the regulation of the sleep/wake cycle
