An Integrated Approach: A Hybrid Machine Learning Model for the Classification of Unscheduled Stoppages in a Mining Crushing Line Employing Principal Component Analysis and Artificial Neural Networks.

This article implements a hybrid Machine Learning (ML) model to classify stoppage events in a copper-crushing equipment, more specifically, a conveyor belt. The model combines Artificial Neural Networks (ANNs) and Support Vector Machines (SVMs) with Principal Component Analysis (PCA) to identify the type of stoppage event when they occur in an industrial sector that is significant for the Chilean economy. This research addresses the critical need to optimise maintenance management in the mining industry, highlighting the technological relevance and motivation for using advanced ML techniques.

The transition from development and disaster risk reduction to humanitarian relief: the case of Yemen during high-intensity conflict.

Discussions on how humanitarian aid and disaster responses can link better with development and disaster risk reduction (DRR) have occurred for decades. However, the reverse transition, from development to relief, is still poorly understood. Using the case of Yemen, this study analyses whether and how development and DRR activities adapted to the emerging humanitarian crisis when conflict escalated in the country.

When Covid-19 meets conflict: politics of the pandemic response in fragile and conflict-affected states.

The Covid-19 pandemic has magnified existing crises and vulnerabilities, but much remains unknown about how it has affected fragile and conflict-affected settings. This paper builds on the theory that hazards become a disaster in interaction with vulnerability and response policies, yet often lead to renewed disaster risk creation. It is based on seven case studies of countries worldwide that experienced social conflict at the advent of the pandemic, covering the period from March-August 2020.

[A case of mycotic keratitis due to Fusarium solani in Valdivia, Chile].

Background: Keratomycosis is one of the most prevalent ophthalmic infections, which needs a specific treatment depending on the nature of the infecting fungus. The prognosis is usually severe and depends on an early diagnosis and suitable therapy.

Case Report: We describe a case of keratitis due to Fusarium solani in a patient from a rural area, who, between May and October 2011, suffered a corneal trauma caused by dust particles in Valdivia, Chile.

[Treatment of distal radius non-union in a three-stage procedure. Case report].

Introduction: Non-union of the distal radius is an infrequent entity. Recently, it has been identified more often and it has been speculated that external fixation and other techniques used to maintain radial length, may create defects that favor the non-union. In chronic injuries, residual deformity and retraction of tissues are difficulties for treatment.
