In addition, this paper will discuss specific societal aspects that can impact reaction and adjustment to disability. In this vein, we will examine the specific effects of societal attitudes and stigma upon individuals with disabilities. Strategies for changing attitudes and facilitating adjustment to disability will also be discussed.展开更多

To investigative the damage of single and sequential strike induced by the EPWs, experimental and numerical investigations are carried out in this paper.Firstly, a series of sequential explosion tests are conducted to provide the basic data of the crater size.Then, a numerical model is established to simulate the damage effects of sequential explosions using the meshfree method of Smoothed particle Galerkin. The effectiveness of numerical model is verified by comparison with the experimental results. Finally, based on dimensional analysis, several empirical formulas for describing the crater size are presented, including the conical crater diameter and the conical crater depth of the single explosion, the conical crater area and the joint depth of the secondary explosion. The formula for the single explosion expresses the relationship between the aspect ratio of the charge ranging from 3 to 7, the dimensionless buried depth ranging from 2 to 14 and the crater size. The formula for the secondary explosion expresses the relationship between the relative position of the two explosions and the crater size. All of data can provide reference for the design of protective structures.展开更多

文摘In this paper, we will address common psychological reactions to disability such as anxiety, depression, denial, and anger in the framework of a stage model. In addition, this paper will discuss specific societal aspects that can impact reaction and adjustment to disability. In this vein, we will examine the specific effects of societal attitudes and stigma upon individuals with disabilities. Strategies for changing attitudes and facilitating adjustment to disability will also be discussed.
