Fibroblasts from patients with idiopathic pulmonary fibrosis (IPF) have been shown to differ normal lung fibroblasts in functional behaviors that contribute the pathogenesis of IPF, including expression contractile proteins and proliferation, but how such vary matrices stiffness matched fibrotic tissue remains unknown. Here, we tested whether pathologic changes matrix control IPF tissue-derived fibroblast functions, compared relative efficacy mechanical cues an antifibrotic lipid mediator,...

Pulmonary arterial (PA) stiffness is associated with increased mortality in patients pulmonary hypertension (PH); however, the role of PA stiffening pathogenesis PH remains elusive. Here, we show that distal vascular matrix an early mechanobiological regulator experimental PH. We identify cyclooxygenase-2 (COX-2) suppression and corresponding reduction prostaglandin production as pivotal regulators stiffness-dependent cell activation. Atomic force microscopy microindentation demonstrated...
The high-speed reduction in a relatively small space, coupled with torque load capacity larger than that of any other standard transmission, positions planetary gear systems as one the most vital components gearing applications today. Structural analysis train is conducted using CATIA software, employing strain full tensor distribution through Finite Element Method (FEM). analysed natural frequencies and vibration modes each component provide essential information for fine-tuning resonances...
The purpose of this paper is to analyze the lubrication quality porous sliding bearings, starting from bearing model and in combination with experimental results aimed at analyzing regimes different working conditions. separation between surfaces by lubricant layer what determines regime. type regime are determined parameters mathematical including typically speed, load, motion, materials, environment, etc., which have an impact on friction. Besides those elements, important such as...
This review paper is an homage to Arvid Palmgren’s pioneering on rolling bearing service life highlight its relevance a century later. It follows the evolution of theory from fundamental research contemporary international standard ISO 281. theory, based previously published papers Stribeck and Hertz, laid basis for later development assessment methodology. Based Weibull probability damage, Lundberg Palmgren introduced stochastic elements explain effect reliability prediction. Harris...
Purpose This paper aims to present the methodology determine Archard’s wear coefficient. By applying this coefficient into numerical simulation of wear, it is possible predict without long lasting and usually expensive experiments. Design/methodology/approach To necessary particles equation calculate K, an experimental investigation proposed. Afterwards, executed in FEM software ANSYS 18.1. Analytical method offered worn volume for cylinder-in-cylinder contact, based on “inclination” inner...
Taguchi method has been used to analyse the influence of coefficient trochoid radius, number revolutions and working pressure on change in flow rate volumetric efficiency trochoidal rotary pump with internal gearing.The as a geometrical parameter pressure, parameters are considered influential factors this paper.Taguchi robust design orthogonal matrices have applied experiment determine degree influence, well their optimum values.The highest values both for obtained radius 1.375, 2000 min -1...
Abstract High‐frequency chest compression (HFCC) is a therapy for cystic fibrosis (CF). We hypothesized that the resonant frequency (f res ), as measured by impulse oscillometry, could be used to determine what HFCC vest settings produce maximal airflow or volume in pediatric CF patients. In 45 subjects, we studied: f , frequencies subjects and generated greatest vol ) flow changes pneumotachometer. Median 32 was 14 Hz (range, 6–30). The rank order of three most common 15 (28%) 12 (21%);...
Purpose This paper aims to develop a simulating model of journal porous metal bearing under elastohydrodynamic conditions and combined (radial, friction thermal) load distribution carry out structural optimization. Design/methodology/approach The structure analysis is carried for each kind separately the bearing, where dynamically loaded simulated. developed by finite elements method using module CATIA V5 software. Further, parameter optimization presented considering elastic deformations...
Polymer based composite sliding bearings are increasingly applied in many industries, due to their economic (usually low cost of production) and technical (good tribological properties) benefits.In order predict life cycle, it is necessary perform numerous experiments evaluate wear rate.This generally quite expensive time consuming.By applying only one series the determining Archard's coefficient, embedding into code Ansys software, possible simulate wear, thus save financial resources.This...
During the last few decades, requirements for modern machine elements in terms of size reduction, increasing energy efficiency, and a higher load capacity standard non-standard gears have been very prevalent issues. Within these demands, main goals are optimization gears’ tooth profiles, as well investigation new profile designs. The presented design idea is based on optimal solutions inspired by nature. Special attention paid to root zones spur order decrease stress concentration values...
