Distribution of deformation types as a function of spray stand-off (compressed chamber) Full size image Conclusion Employing multiple flat-fan nozzles at an orientation of 25°, a set of laboratory experiments was designed and executed to understand the technical feasibility of high-pressure water ...
Maritime transport, throughballast water, is the main vector of introduction of nonindigenous species in the Hellenic Seas. Besides this, and in response to increasing temperature, fish and plankton are expanding theirgeographical distributionfurther north, and the introduction of nonindigenous (NIS) spec...
In turn, the distribution ratio of each index dimension of the paper company is obtained. The value of each vector in the best projection direction represents each indicator's corresponding weight, and each indicator’s importance in evaluating the quality of corporate water disclosure can be ...
We checked all variables for normal distribution using the Shapiro test128. As all the variables showed to be non-normally distributed, we selected the non-parametric Mann–Kendall test129 to assess the correlation between pairs of the four variables, which is reported as a correlation matrix (...
Water resource modeling is an important means of studying the distribution, change, utilization, and management of water resources. By establishing various models, water resources can be quantitatively described and predicted, providing a scientific basis for water resource management, protection, and plan...
