The authors have obtained the formulas to calculate the parameters of railguns at periodic nonsinusoidal current.Such parameters as the average effective magnetic density of current pulse in the space between the railgun tires, the equivalent inductance and resistance, the average temperature of tires at their adiabatic heating as well as the avera
Lifelong infection of the gastric mucosa by Helicobacter pylori can lead to peptic ulcers and gastric cancer.However, how the bacteria maintain chronic colonization in the face of constant mucus and epithelial cell turnover in the stomach is unclear.Here, we present a new model of how H.pylori establish and persist in stomach, which involves the co
In this paper, we study a new class of single-iteration scheduling algorithms for inputqueued switches based on a new arbitration idea called highest rank first (HRF).We first demonstrate the effectiveness of HRF by a simple algorithm named Basic-HRF.In Basic-HRF, virtual output queues (VOQs) at an input port are ranked according to their queue siz
The cut flower industry has a global reach as flowers are often produced in countries around the equator and transported by plane or ship (reefer) mostly to the global north.Vase-life issues are often regarded as linked to only postharvest conditions while cultivation factors are just as important.Here, we review the main causes for quality reducti
Abstract Background International human right standards place obligations on prison authorities to take reasonable steps to prevent suicides in prison and to investigate those which occur.Those human rights instruments contain minimum standards which states must abide by.Human rights principles can also be used in analysis of why suicides occur in
