Characterization and potential usage of selected eggshell species.

Today's awareness of environmental pollution and the idea of creating a reuse area for waste is one of the trend topics. The base opinion, regarding the reuse of any material is that all resources are inherently limited in the world. In the ethical approach, it is a moral issue that people take responsibility for future generations to protect nature.

Eggshell as a biomaterial can have a sorption capability on its surface: A spectroscopic research.

In this study, eggshell as a biomaterial was used as an adsorbent. This natural waste material is easy to access and cost-free. The surface of the eggshell with its porous structure showed affinity to adsorb damaging chemicals.

Coping by redefinition: cognitive appraisals in mothers of children with autism and children without autism.

To test a model of how mothers cope with the stresses of raising a child with autism (Tunali & Power, 1993), mothers of children with and without autism were interviewed. As predicted, mothers of autistic children: (1) placed less emphasis on career success and were more likely to believe that mothers of young children should not work outside of the home; (2) spent more leisure time with their extended family; (3) placed less emphasis on others' opinions of their child's behavior; (4) placed more emphasis on spousal support and parental roles in their discussions of marriage; (5) had more difficulty understanding their child's behavior; and (6) showed a marginally significant difference in their tolerance of ambiguity. Moreover, mothers of children with autism who showed these characteristics had the greatest life satisfaction overall.
