Patient and public involvement in oesophageal cancer survivorship research.

Background: Good clinical research is often conducted in close collaboration between patients, the public, and researchers. Few studies have reported the development of patient and public involvement (PPI) in research outside the United States and the United Kingdom, and for patients with more aggressive cancers. The study aimed to describe and evaluate the development of PPI in oesophageal cancer survivorship research in Sweden by the use of a framework to support the process.

Severe reflux, sleep disturbances, and health-related quality of life after esophageal cancer surgery.

Purpose: Esophagectomy for cancer is an extensive procedure often followed by severe complications. This study investigated whether patients with severe symptoms of reflux are more likely to have sleep disturbances and reduced health-related quality of life (HRQL) after esophagectomy.

Methods: This Swedish nationwide prospective cohort study encompassed all patients who had undergone esophagectomy for cancer between 2013 and 2018.

Probing heat generation during tensile plastic deformation of a bulk metallic glass at cryogenic temperature.

Despite significant research efforts, the deformation and failure mechanisms of metallic glasses remain not well understood. In the absence of periodic structure, these materials typically deform in highly localized, thin shear bands at ambient and low temperatures. This process usually leads to an abrupt fracture, hindering their wider use in structural applications.

Evaluating the Tensile Properties of Aluminum Foundry Alloys through Reference Castings-A Review.

The tensile properties of an alloy can be exploited if detrimental defects and imperfections of the casting are minimized and the microstructural characteristics are optimized through several strategies that involve die design, process management and metal treatments. This paper presents an analysis and comparison of the salient characteristics of the reference dies proposed in the literature, both in the field of pressure and gravity die-casting. The specimens produced with these reference dies, called separately poured specimens, are effective tools for the evaluation and comparison of the tensile and physical behaviors of Al-Si casting alloys.

On copper diffusion in silicon measured by glow discharge mass spectrometry.

Copper contamination occurs frequently in silicon for photovoltaic applications due to its very fast diffusion coupled with a low solid solubility, especially at room temperature. The combination of these properties exerts a challenge on the direct analysis of Cu bulk concentration in Si by sputtering techniques like glow discharge mass spectrometry (GDMS). This work aims at addressing the challenges in quantitative analysis of fast diffusing elements in Si matrix by GDMS.
