An aero engine, as the core power equipment of the aircraft, enables safe and stable operation with a very high reliability index, and is an important guarantee in flight.The open rotor turbine engines (contra-rotating propeller) have stood out as a research hotspot for aviation power equipment in recent years due to their outstanding advantages of
Verification and validation of detonation modeling
The mathematical model used to describe the detonation multi-physics phenomenon is usually given by highly coupled nonlinear partial differential equations.Numerical simulation and the computer aided engineering (CAE) technique has become the third pillar of detonation research, along with theory and experiment, due to the detonation phenomenon is
Extra-gastrointestinal stromal tumor arising in the lesser omentum with a platelet-derived growth factor receptor alpha (PDGFRA) mutation: a case report and literature review
Abstract Background Gastrointestinal stromal tumors (GIST) arising from sites other than the gastrointestinal (GI) tract, termed extra-gastrointestinal stromal tumors (EGIST), are rare.Among EGIST, those with platelet-derived growth factor receptor alpha (PDGFRA) mutations are even rarer, with only a few cases reported.About 80% of GIST has KIT mut
The state of scientific development of the problem of operational and investigative counteraction by criminal police units to the promotion of criminally illegal activities of an organized group or criminal organization
The article examines the state of scientific development of assistance to criminally illegal activities of an organized group or criminal organization in the context of consideration of various aspects of operational and investigative counteraction to criminal wrongdoing by criminal police units.The relevance of the topic is proved, the PullOver wi
The new study of some characterization of canal surfaces with Weingarten and linear Weingarten types according to Bishop frame
Abstract In this paper, we have a tendency to investigate a particular Weingarten and linear Weingarten varieties of canal surfaces according War Bow to Bishop frame in Euclidean 3-space E 3 satisfying some Hard, Chewy, Sour and Fizzy Candy fascinating and necessary equations in terms of the Gaussian curvature, the mean curvature, and therefore the
