Hydrogen peroxide treatment is a cost-effective and simple method to improve the bioactivity of titanium implants. In this study, the effects of chloride ion concentration and temperature of hydrogen peroxide on the surface treatment of titanium were investigated using X-ray diffractometry (XRD), Field Emission-Scanning Electron Microscopy (FESEM), and tests in order to determine wettability and a

En översiktlig presentation av av tre äldre skräckserietidningar för en yngre kvinnlig publik: brittiska Spellbound (1976-1978), brittiska Misty (1978-1980) och tyska Vanessa (1982-1990).

Pulmonary vein isolation (PVI) is considered a standard treatment of paroxysmal atrial fibrillation aiming to restore and maintain sinus rhythm. The purpose of this study is to analyse how the PVI treatment affects the electrical conduction pattern in the atria. We have compared the morphology of P wave loops extracted from the vectorcardiogram (VCG) before and after PVI. Ten patients suffering fr

Background: It is unclear if a non-radical diagnostic biopsy entails a higher risk for metastasis and poorer survival for patients with cutaneous head and neck melanoma (cHNM). Aims/objectives: To assess whether or not initial diagnostic biopsy modality and radicality (clear, positive, or narrow histopathological margins) influence recurrence and survival in patients with cHNM. Materials and metho

In this paper we propose a design methodology to partition dataflow applications on a multi clock domain architecture. This work shows how starting from a high level dataflow representation of a dynamic program it is possible to reduce the overall power consumption without impacting the performances. Two different approaches are illustrated, both based on the post-processing and analysis of the ca

Background: The COVID-19 pandemic has rapidly led to some of the most revolutionary changes in private and professional life around the world. While the extent and duration of these changes are not certain, they have already had a great impact on travel patterns. This is also the case in Sweden, despite its relatively liberal approach to restrictions, which relies on voluntary measures such as soc

n this paper, we introduce a constraint programming-based approach for the optimization of area and of reconfiguration time for communication networks for a class of regular 2D reconfigurable processor array architectures. For a given set of different algorithms the execution of which is supposed to be switched upon request at run-time, we provide static solutions for the optimal routing of data b

Enlargements of distal airspaces can indicate pathological changes in the lung, but accessible and precise techniques able to measure these regions are lacking. Airspace Dimension Assessment with inhaled nanoparticles (AiDA) is a new method developed for in vivo measurement of distal airspace dimensions. The aim of this study was to benchmark the AiDA method against quantitative measurements of di

This article is the outcome of two research trips to the Jain caves at Ellora, the purpose of which was to photograph the best preserved murals found there, works of art that were largely undocumented in any available literature. The article documents and portrays the best preserved paintings in detail found on the walls and ceiling of one of the smaller caves belonging to the largest Jain cave coThis article is the outcome of two research trips to the Jain caves at Ellora, the purpose of which was to photograph the best preserved murals found there, works of art that were largely undocumented in any available literature.

Inverse problems are important in quantum mechanics and involve such questions as finding which potential give a certain spectrum or which arrangement of atoms give certain properties to a molecule or solid. Inverse problems are typically very hard to solve and tend to be very compute intense. We here show that neural networks can easily solve inverse problems in quantum mechanics. It is known tha

The CKD-EPI creatinine-based estimation equation for glomerular filtration rate (GFR) cannot be used in children, overestimates GFR in young adults, and its combination with the KDIGO recommended pediatric CKiD (Schwartz bedside) equation causes implausible increases in estimated GFR when switching from pediatric to adult care. By establishing sex-specific creatinine growth curves for children and

MicroLED technology is expected to be the technology of choice for next-generation displays. Its advantages in various applications are reviewed. The challenges of microLED manufacturing, including red microLED realization, adequate efficiency, mass transfer, and structure and process design from a system perspective, are discussed with a special emphasis on how nano-scale material science may ope

Desire for life and protecting lives has come to the fore during the pandemic. Borders have been closed to stop the spread of Covid-19. The virus does not respect borders, yet physical distance is crucial. Three things have become clear. One is the level of uncertainty about which measures are most efficient. The other is that the neo-liberal philosophy with “just in time” deliveries on a global m

Gut-associated lymphoid tissues (GALTs) comprise key intestinal immune inductive sites, including the Peyer’s patches of the small intestine and different types of isolated lymphoid follicle (ILF) found along the length of the gut. Our understanding of human GALT is limited due to a lack of protocols for their isolation. Here we describe a technique that, uniquely among intestinal cell isolation p
