X-ray Thermo-Diffraction Study of the Aluminum-Based Multicomponent Alloy AlZnSiMg.

Newly designed multicomponent light alloys are giving rise to non-conventional microstructures that need to be thoroughly studied before determining their potential applications. In this study, the novel AlZnSiMg alloy, previously studied with CALPHAD methods, was cast and heat-treated under several conditions. An analysis of the phase evolution was carried out with in situ X-ray diffraction supported by differential scanning calorimetry and electron microscopy.

[Study of knowledge, attitudes, and practices related to leishmaniasis: evidence of government neglect in the Colombian Darién].

American cutaneous leishmaniasis (ACL) is considered a public health problem worldwide, and incidence in Colombia is 12,000 cases per year. Colombia has implemented control programs for years which have often overlooked the social, economic, and demographic characteristics of the regions where the disease occurs. As part of an epidemiological study, this article presents the results of a survey on knowledge, attitudes, and practices (KAP) related to leishmaniasis in rural populations in Acandí in the Colombian Darién.

Psychosocial assessment for victims of violence in Peru: the importance of local participation.

This paper describes a pilot study assessing the psychosocial impact of political violence in the Peruvian Andes, utilizing a collaborative approach with local professionals and communities. The study team prioritized dialogue and information exchange with the local professional community and villagers participating in the assessment in order to raise awareness of psychosocial issues and provide education and support. Participation in the pilot study had positive therapeutic effects for villagers, and inspired ongoing discussion groups to address psychosocial problems in communities.
