Have a look around the classroom and name some of the balanced forces in action on different objects. Gravity Table’s Upthrust Unbalanced Forces Air resistance is pushing upwards The man and the parachute are slowly falling to the ground. Which forces are acting on the parachute? Which force ...
The ideas of quantum zero-point energy may be used to evaluate forces arising in electromagnetism, nuclear physics, and pair theory. This article is a review of the calculations involving electromagnetic theory, where the forces are termed long-ranged van der Waals forces, or retarded dispersion ...
Joint-related disability represents a substantial global health burden and is a frequent consequence of osteoarthritis (OA), in which bone shape is altered and cartilage is lost, causing pain and preventing smooth motion of the joints. OA and failure of total joint replacement (TJR), later in ...
The need for high-speed high-payload craft has led to a considerable interest in vehicles capable of bridging the gap between conventional ships and aircraft. One such concept uses the forward motion of the craft to create aerodynamic fo... AGW Williams - 《Cranfield University》 被引量: 4发...
The appropriate centering force terms are added to the ion-focused regime hose equations and their effect on hose development is calculated. It is found that while hose at very high frequencies is stabilized, the overall suppression is only moderate and other stabilization processes need to be expl...
revealing the indirect effects of the cold dark matter (CDM) in the form of heavy neutral leptons [1– 8] or supersymmetric particles [7, 9, 10], indirect effects of dark matter annihilation had been the subject of intensive studies in the data on the cosmic rays (CR) and gamma ...
The military has been considered a pioneer of equal opportunity among the nation's institutions, where the advancement process is both well defined and based on merit, and the promotion process looks at everyone (Moskos and Butler, 1996; Segal, 1989; Quester and Gilroy, 2002). Various models...

A Kolmogorov-Smirnov test (KS-test) was used to compare size distributions, which provided a KS-test score, indicating a significant decrease (−1), increase (+1), or no change (0) in adhesion size, and a p-value. Furthermore, the maximal distance (D-statistic) between distributions ...
