Steady-state combustion is possible up to a factor of 1/e (1/2) decrease in the burning rate compared to the original value. An explanation is given for the weak manifestation of the negative erosion effect with a decrease in the initial propellant temperature: reducing the threshold rate of...
aAthletic sportswear market a key for cotton industry 正在翻译,请等待... [translate] aIt is usually the case that increasing hardness has either no effect or a negative effect on erosion resistance. 它通常是实际情形增长的坚硬没有作用或一个消极作用在侵蚀抵抗。 [translate] ...

The function of filters in a hydraulic system is to maintain fluid cleanliness. Given that the objective of maintaining fluid cleanliness is to gain maximum service life from the system components, it is imperative to understand that some filter locations can have the opposite effect, the suction ...
The enhancement of the evanescent components in the imaging plane can be accounted for by the effect of the second metalens. Not surprisingly, an array of sub-wavelength scatterers can induce sub-wavelength details in the near-field. The question is to determine whether this evanescent wave-field...
has devastating effects on the environment, including the loss of fertile land and crops. Areas with high soil erosion are also more vulnerable to flooding, mudslides, dust storms, and water pollution. Erosion usually occurs when soil is exposed to moving water, hard rain, and strong winds. Wi...
The research presented in this paper deals with the issue of invasive plant species. Invasive plants are characterized with the high regeneration potential and with a negative effect on populations of our native species and habitats. The occurrence of these plant taxon at a given site is not natu...
This beam causes erosion of the polymer surface removing atomic and molecular ions. These newly created ions, composing what is called the secondary ion beam, are then analyzed as a function of mass and intensity. Depth of detection for SIMS is of the order of 20 to 50 Angstroms. Because ...
Extreme flood events are predicted to have a negative impact on soil quality. Currently, there is a lack of information about the effect of agricultural practices on soil functioning and microbial processes under these events. We hypothesized that the impact of flooding on soil quality will be exa...
