Mathematical model for calculating pressure in a pulsating combustion chamber

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2022
Due to insufficient knowledge of the processes occurring in the chambers of pulsating combustion, as well as lack of mathematical dependencies that make it possible to fully describe the parameters of such chambers, the authors of this article present a ...

Recurrent Hypothermia and Autonomic Dysfunction Secondary to Shapiro Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 44‐year‐old man presented with recurrent hypothermia, diaphoresis and hypertension. Extensive investigation for infectious, inflammatory, metabolic and endocrine aetiologies was negative. MR scan of the brain demonstrated no lesions but revealed callosal dysgenesis, consistent with Shapiro syndrome.

Asteroseismology of Eclipsing Binary Stars in the Kepler Era

, 2014
Eclipsing binary stars have long served as benchmark systems to measure fundamental stellar properties. In the past few decades, asteroseismology - the study of stellar pulsations - has emerged as a new powerful tool to study the structure and evolution ...

Effect of Venous Pressure on Volume Pulsation

Experimental Biology and Medicine, 1939
In a previous study it was noted that, with ligation of the main venous outlet from the lower extremity of the dog, a marked reduction in peripheral pulse volume occurred.1 The present observations were made to throw some light on the mechanism of these changes.In 14 dogs the volume of pulsations in the hind foot was determined by adapting a specially ...

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

Arthritis Care &Research, EarlyView.
Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.

Experimental Isolation and Coherence Analysis of Pressure Pulsations in Tubular Pumps: Unveiling the Impact of Impeller Rotation on Flow Dynamics

Machines
Tubular pump systems (TPSs) represent a critical class of large-scale turbomachinery for low-head water transport, where mechanical reliability is often challenged by complex internal flow dynamics.

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

Advanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.
