The most expensive component in a conventional solar photovoltaic (PV) system is the solar module cell. The module cost could be reduced if low-cost reflector materials are used to concentrate solar energy flux across a small module area. Three reflector materials were studied for fill-factor improvements in low concentrating system. These were anodized aluminium, rolled aluminium foil and miro re

The goal of this paper is to determine whether the photoplethysmography (PPG) can replace the ECG-based detection of heart rate turbulence. Using the PPG, classification of ventricular premature beats (VPBs) is accomplished with a linear classifier. The two conventional parameters turbulence onset and slope are studied together with a recently introduced parameter characterizing turbulence shape.

The last twenty years have brought about a significant increase in the awareness of war practices that harm women, including rape and sexual abuse. However, focusing on women alone is not sufficient if gendered and racialised power hierarchies in the civilian and military worlds are to be understood. Experiences from international peacekeeping since 2000 foreground the need for an intersectional l

Resistance to Russia’s aggression is being shaped by how decentralised and data-centric global rules have become.

The Swedish Hernia Register (SHR) is a national quality register with more than 350,000 prospectively registered groin hernia repairs. Studies from the SHR have addressed important and clinically relevant issues within the field of laparoscopic groin hernia surgery and the aim of this paper is to present five of the most innovative patient-oriented publications including analysis of laparoscopic h

To show the impact of interviews for European legal studies, this article summarizes the earlier findings of two books, the first by Arold on the legal culture of the European Court of Human Rights (ECtHR), and the second by Arold Lorenz, Groussot and Petursson on the legal culture of the European Court of Justice (CJEU) and European human rights culture. In doing so, this article draws a portrait

This paper describes a method to minimize bearing forces as well as bearing and housing mass for a multistage gear reduction. This is done by finding the optimum dog-leg angles for the stages while leaving other aspects of the design unaltered. The optimization is demonstrated first for spur gears, and then for helical gears typically used in electric vehicles. A numerical example shows how bearin

Introduction: Many studies have assessed the prevalence of alcohol consumption in Iran. In this study, we investigated the prevalence of alcohol consumption in different groups. Material and Methods: We searched international and databases including PubMed, Web of Science, Scopus and we searched two main Farsi-language index databases including Scientific Information Database (SID) and the Irandoc

Human papillomaviruses (HPV) are epitheliotropic DNA tumor viruses that are prevalent in the human population. A subset of the HPVs termed high-risk HPVs (HR-HPVs) are causative agents of anogenital cancers and head-and-neck cancers. Cancer is the result of persistent high-risk HPV infections that have not been cleared by the immune system of the host. These infections are characterized by dysregu

Limonene and linalool are among the most common fragrance terpenes used in everyday products. They are pre-haptens, forming hydroperoxides (Lim-OOHs, Lin-OOHs) upon oxidation and inducing frequent positive patch test reactions in patients with dermatitis, and yet they are not routinely tested in Europe. This review evaluates current patch testing with Lim-OOHs and Lin-OOHs by asking whether hydrop
