NATURAL OSCILLATIONS FREQUENCIES OF HYDRAULIC ACCUMULATOR ELEMENTS SIMULATION
Авіаційно-космічна техніка та технологія, 2017 The paper presents simulation results of Heat Controlled Accumulator (HCA) structural parts natural frequencies. Two different mounting brackets were analyzed including impact of interior parts of accumulator. Find out that the minimal frequencies are in

Comparative study between random vibration and linear static analysis using Miles method for thruster brackets in space structures [PDF]
INCAS Bulletin, 2017 Random vibrations occur during the launch at the fastening interface between thruster brackets and basic support of satellite. These are generated in the launcher by the motion of some mechanical parts, combustion phenomena or structural elements excited

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

DIAGNOSIS OF DAMAGES OF PLANE WINGS ATTACHMENT POINTS USING VIBRATION’S PARAMETERS
Приборы и методы измерений, 2015 A method of diagnostics of power structures based on shock excitation of eiqenmodes and used as a diagnostic parameter of modal characteristics (natural frequencies and mode shapes) is proposed.

The calculation of the dynamic characteristics of the spillway of the dam
Magazine of Civil Engineering, 2022 The object of the presented studies is a concrete spillway dam of a run-of-river hydroelectric power station. The modes of vibrations are determined on the basis of a solid model, which is necessary to take into account possible resonant phenomena in the

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Non-uniform Euler-Bernoulli beams’ natural frequencies
Ingeniería e Investigación, 2011 This paper has studied the problem of natural frequencies for Euler-Bernoulli beams having non-uniform cross-section. The numerically-obtained solutions were compared to asymptotic solutions obtained by the Wentzel-Kramers-Brillouin (WKB) method.

Active Vibration-Based Condition Monitoring of a Transmission Line
Actuators, 2021 In the power system, the transmission tower is located in a variety of terrains. Sometimes there will be displacement, inclination, settlement and other phenomena, which eventually lead to the collapse of the tower. In this paper, a method for monitoring

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
