ambivalent trust and ontological representations of death as latent factors of religiosity

AbstractThe studies on the relationship between religiosity and the management of trust in postmodern society are an emerging field of research. The psychological contribute of the attachment theory shows how early relationships with the parental figures determine the adult attachment styles and the related dispositions to trust and religiosity. Lack of trust is a critical aspect of the insecure attachment styles: the avoidant and the anxious. This study in focused on these two traits, considering their level of trust compared to religiosity and representations of death. The Interpersonal Trust Survey, The World Health Organization Quality Of Life-Spirituality, Religiousness and Personal Beliefs, the Testoni Death Representations Scale and the Experiences in Close Relationships-Revised were utilized. The results illustrated different expressions of trust in avoidant and anxious styles

Reduction of potassium cyanide usage in a consolidated industrial process for gold recovery from wastes and scraps

The main purpose of the present work is to improve the understanding of an industrial process that exploits the synergic action of cyanide ion and three-nitrobenzene-sulphonate for the selective removal of precious metals from various matrices. It has been observed that the cyanide dissolves first gold from the surface, forming dicyanoaurate gold complexes, but this reaction alone is not sufficient to dissolve gold with the observed velocity. A deeper knowledge of the chemical mechanisms can potentially improve the process competitiveness. Important reaction factors have been identified and analyzed. It has been demonstrated that the cyanide amount presently utilized is excessive. Possible reduction products have been also identified. The results can help the search for cyanide reduction and substitution. Yield and velocity optimization, together with a solution toxicity reduction can pave the way to eco-friendly processes for the leaching of noble metals
