Mental Health Status and Fear of COVID-19 in Young Adult Male Inmates in Portugal

Introduction Incarcerated individuals are subject to a heightened risk of both mental and physical ailments. Hence, it is important to conduct regular assessments of their mental well-being and other potential health hazards. Objectives The aim of this study is to examine the subjective experience of fear related to COVID-19 and the psychological consequences of the pandemic among a cohort of young adult male c...

The role of physical properties in explosive welding of copper to stainless steel

This paper investigates the effects of the physical properties on the microstructure and weldability of explosive welding by joining two metals with a significant contrast in thermophysical properties: stainless steel and copper. Sound welds between stainless steel and copper were obtained, and the interfacial morphology was wavy, regardless of the position of the materials. The weldability of dissimilar pairs ...

Influence of Temperature and Packaging Materials in Ewe’s Cheeses Storage

One of the major concerns in cheese production is the shelf life extension, and the use of different conservation methods is extremely important. During commercialization period several problems often appear, like molds or packages that change the characteristics of cheese, which concerns the producers because they can lead to significant economic losses. The objective of this work was to evaluate the quality o...

Explosive welding of aluminium to stainless steel using carbon steel and niobiu...

This work aimed to study aluminium to stainless steel explosive welds produced using two different interlayers: carbon steel and niobium. The use of each interlayer was analysed and compared microstructurally and mechanically using many characterisation techniques. The final joints using both interlayers presented favourable interfacial microstructure: waves on both interfaces. However, the joint using the carb...

Physical activity promotion tools in the Portuguese primary health care: An imp...

Background: This paper aims to discuss how physical activity (PA) brief assessment, brief counseling, and self-monitoring tools were designed and implemented in the Portuguese National Health Service (NHS), and to report on their current use by health professionals and citizens. Methods: Three digital tools to facilitate PA promotion in primary health care (PHC) were developed: 1) a PA brief assessment tool was...

Friction stir welding and explosive welding of aluminum/copper: process analysis

The 6082 aluminum alloy was welded to copper-DHP by friction stir welding and explosive welding. The effect of each welding process on the microstructural evolution, the intermetallic phases distribution, and the mechanical behavior of both types of welds was analyzed and compared. The microstructural changes proved to be much more expressive in friction stir welding due to the larger area under plastic deforma...
