Metal contamination of water bodies has attracted global attention owing to its environmental toxicity, abundance and persistence. Metals such as arsenic, cadmium and mercury are of greater concern since they are toxic even at low concentrations. Mercury is present at 1000 times lower concentrations than the other two metals, but still has a negative impact on the environment due to its high trans

In this study, we developed a nanoparticle-based mesoporous composite that consisted of silicate-titanate nanotubes (STNTs) supported in hydrogel chitosan beads (STNTs-Ch beads) and was studied for Cd2+ adsorption. By using Fourier-transform infrared spectroscopy, transmission and scanning electron microscopy coupled to an energy-dispersive X-ray spectrometer, we coulddetermine that the hollow STN

Objectives: Depressive symptoms in the elderly have been shown to be associated with increased mortality. The purpose of this study was to examine symptoms of depression in octogenarian men and their association with all-cause mortality, and whether physical, cognitive and social factors influence this association. Methods: Out of the 703 initially included 55-years-old men, from the prospective c

We present vertical InAs/InGaAsSb/GaSb nanowire tunnel FETs (TFETs) on Si demonstrating subthreshold swing (S) of 32 mV/dec with ION = 4 µA/µm for IOFF = 1 nA/µm at VDS = 0.3V. The demonstrated drive currents is the highest reported for a TFET with S below 40 mV/dec resulting in a transconductance efficiency as high as 100 V-1. These results have been achieved by optimizing the source segment grow

We study the radial migration of stars as a function of orbital action as well as the structural properties of a large suite of N-body simulations of isolated disc galaxies. Our goal is to establish a relationship between the radial migration efficiency of stars and their vertical action. We aim to describe how that relationship depends on the relative gravitational dominance between the disc and

Internet of Things (IoT) is the next generation of network scenario where billions of devices are connected to the internet and capable to communicate with each other. However, they are especially vulnerable to Denial of Service (DoS) attack, which typically launched by overloading the server with bogus messages. Hence, unnecessary computation is performed by the IoT units, which can seriously wor

Background: The epidermal growth factor receptor (EGFR) is pivotal for growth of epithelial cells and is overexpressed in several epithelial cancers like head and neck squamous cell carcinoma (HNSCC). EGFR signalling is also involved in diverse innate immune functions in epithelia. We previously found a role for EGFR in modulating the complement system in skin, this prompted an investigation into

This article is written in the intersection of eschatology and theology of religions. It argues that apart from the well-known discussion of "Who will be saved?", there is a related question that is often overlooked. The Jewish theologian Jacob Neusner articulates this question in the following way: How can I form a theory of the other in such a way that within my own belief I can respect the othe

Food safety and unnecessary prescription of antibiotics are real concerns worldwide. Laser-based spectroscopy research at both South China Normal University as well as at Lund University, Sweden to meet these problems will be covered.

The paper reports a study of change in causal explanations in therapeutic conversations. It shows how attribution of thoughts, feelings and behaviours which are experienced as problematic, e.g. embarrassing, awkward, absurd or painful, is changed from internal to more external. Namely, analysis focuses on how dispositional attribution – attributing problematic thoughts, feelings and behaviours to

Plasma concentrations of many cardiovascular and inflammatory proteins are altered after ST-elevation myocardial infarction (STEMI) and may provide prognostic information. We conducted a large-scale proteomic analysis in patients with STEMI, correlating protein levels to infarct size and left ventricular ejection fraction (LVEF) determined with cardiac magnetic resonance imaging. We analysed 131 c

Background: Short-acting β2-agonist (SABA) bronchodilators help alleviate symptoms in chronic obstructive pulmonary disease (COPD) and may be a useful marker of symptom severity. This analysis investigated whether SABA use impacts treatment differences between maintenance dual- and mono-bronchodilators in patients with COPD. Methods: The Early MAXimisation of bronchodilation for improving COPD sta

På 60-talet kryllade det av humanistiska akademiker i tv-husets korridorer. De kom direkt från universiteten och blev experter i frågeprogrammen – men också programledare, scriptor, redaktörer, scenografer och nöjeschefer. Hur kom det sig att lärda akademiker blev ansvariga för tv-underhållning? Och vad var det egentligen som hände sen? Historikern Johan Östling stiftar bekantskap med akademikerna
