Dynamic response at the terminus of oblique intersecting joints subjected to stress waves
Deep Underground Science and Engineering, EarlyView.This study derives the propagation equation for stress waves impinging upon nonlinear oblique intersecting joints. It analyzes the dynamic response at the terminus of nonlinear oblique intersecting joints subjected to stress waves. Abstract To investigate the dynamic response at the terminus of oblique intersecting joints subjected to stress waves, a ...

European Journal of Organic Chemistry, EarlyView.Threefold reduction of 9,10,11‐triptindanetrione with LiAlH4 or NaBH4 yields exclusively the C3‐symmetric triol, suggesting an intracomplex (“rolling”) mechanism. However, use of LiAlH4/LiAlD4 (1 : 1) reveals a preceding hydride exchange. Mechanistic implications are discussed including the reduction of the related diketone.

European Journal of Organic Chemistry, EarlyView.3D‐printed geopolymers are presented as efficient and reusable heterogeneous catalysts for the Knoevenagel condensation. Under mild and green conditions, they promote the high‐yield synthesis of diverse α‐cyanoacrylates with remarkable stability and scalability.

Experimental effects of wing location on wing-body pressures at supersonic speeds [PDF]
An experimental study was performed at supersonic speeds to measure wing and body spanwise pressure distributions on an axisymmetric-body delta wing model on which the wing vertical location on the body was systematically varied from low- to high-mounted

Reclaimed Homophobic Hate Speech Backfires: Desensitization and Mood Deterioration
European Journal of Social Psychology, EarlyView.ABSTRACT Reclaimed hate speech is generally seen as a positive phenomenon by minority groups and, to some degree, by majority groups. However, previous research has not examined whether it might produce harmful effects similar to traditional hate speech.

Some aspects of hybrid-zeppelins [PDF]
, 1975 To increase an airship's maneuverability and payload capacity as well as to save bouyant gas it is proposed to outfit it with a slender delta-wing, which carries about one half of the total take-off weight of the vehicle.

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit

Flight measured downwash of the QSRA [PDF]
Several reports have been written on the performance of the Quiet Short-Haul Research Aircraft, which shows the advantages of upper-surface blowing or the propulsive-lift wing as it applies to lift, maneuverability, and short takeoff and landing.

Unsteady CFD Analysis of a Delta Wing Fighter Configuration by Delayed Detached Eddy Simulation [PDF]
, 2008 While the flow physics of generic delta wings with sharp leading edges are largely understood, realistic configurations with rounded leading edges and canards are still of scientific and industrial interest.
