Emistim CAS is a natural plant growth regulator, with less side-effect. The research performed an assessment on Emistim CAS application in watermelon cultivation in a greenhouse. The results showed that 0.11% Emistim CAS increased reducing sugar by 15.49%, soluble solid by 13.7%, Vc content by 3.72%, titratable acid by 18.1%, and yield per hectare by 18.01%, so that watermelon quality and yield were both improved. Emistim CAS can be widely promoted in watermelon cultivation in future.展开更多

Services have been attracting increasing attention from industry and academic field as an effective mean to satisfy such varied customer requirements. In order to make a profit, it is important for companies to build and maintain long-term relationships with customers. Therefore, service providers should maintain their service quality and always satisfy their customers. To realize highly reliable product or services, in general, it is an effective approach to prevent failures from occurring in the use phase. Therefore, it is necessary that analysts identify the factors that could cause service failure and take appropriate measures against the target failure factor in advance. However, service failure factors are varied compared to physical products because service failures occur due to uncertainty elements such as human factors. In this study, we aim to enable service analysts to identify the critical failure factor from a number of failure factors. To achieve this, we identify complex failure factors and relationships among them from the viewpoint of the field where the service provided. This paper proposes a method for structuring the causal sequence between service failure factors by using a method of system modeling.展开更多

In this paper, the authors first define the security model for threshold proxy re-signature scheme, and then propose two threshold proxy re-signature schemes based on Ateniese-Hohenberger＇s and Shao-Cao-Wang-Liang＇s approach.展开更多

We illustrate the application of our method by solving several examples and present numerical results that show the accuracy of the truncated series approximations to the solutions.展开更多

We find that the EOS of nuclear matter will become stiffer as e, d in the self- interaction of σ meson increase when the coeffcients except aω in Гω, in which the opposite occurs, are fixed. On the other hand, greater values of aσ, bσ, cσ, aω, dω and smaller values of dσ, bω, cω will lead to stiffer EOS ifc and d are fixed. Besides, greater values of Гω lead to stiffer EOS in high density region for the EOS with same incompressibility coefficient at saturation density.展开更多
