Missile power plant is a key factor in determining the missile’s range.This paper analyzes and discusses the current patented technologies and application Recliner status of integrated solid rocket ramjet engines in foreign countries (USA, Russia, Europe).Based on the analysis, the key technologies for the development of integrated solid ro
We report on progress towards the Hip Flasks development of an Action Concept Inventory (ACI), a test that measures student understanding of action principles in introductory mechanics and optics.The ACI also covers key concepts of many-paths quantum mechanics, from which classical action physics arises.We used a multistage iterative development cy
Abstract In order to reduce the radar cross section (RCS) of the unmanned aircraft while suppressing its infrared signature, a comprehensive design method (CDM) based on sorting factor Pareto solution is presented.The physical optics and physical diffraction theory are used to evaluate the electromagnetic scattering characteristics Lifting Straps o
In the Canadian prairies, pulse crops such as field pea (Pisum sativum L.) and lentil (Lens culinaris L.) are economically important and widely grown.However, in recent years, root rot, caused by a variety of fungal and oomycete pathogens, including Aphanomyces euteiches, has become a limiting factor on yield.In this study, we examined the impacts
Although the traditions of equestrianism in Poland goes back a long way, it was not until 1880 that the first equestrian competitions were organized in Warsaw.In the following years, the interest of the Polish society in equestrian competition had been growing and led to the creation of equestrian-breeding associations, which actively conducted spo
