En kopp kaffe och Marx, tack!

Bokcaféerna spelade en avgörande roll inom den västeuropeiska vänsterns tryck- och mediekultur under 1970-talet. Även i Sverige gjorde bokcaféerna omfattande avtryck inom kultur- och samhällslivet, till exempel genom att etablera den politiska pocketgenren. När fenomenet dog ut under nästa decennium försvann en betydande plattform för den radikala folkbildningen.

Är du rysk eller?

Vibration thresholds in carpal tunnel syndrome assessed by multiple frequency vibrometry : a case-control study

Background: Carpal tunnel syndrome (CTS) is the most common compression neuropathy, but there is no gold standard for establishing the diagnosis. The ability to feel vibrations in the fingertips is dependent on the function in cutaneous receptors and afferent nerves. Our aim was to investigate vibration perception thresholds (VPTs) in patients with CTS using multi-frequency vibrometry.Methods: Six

The calcium channel subunit gamma-4 is regulated by MafA and necessary for pancreatic beta-cell specification

Voltage-gated Ca2+ (CaV) channels trigger glucose-induced insulin secretion in pancreatic beta-cell and their dysfunction increases diabetes risk. These heteromeric complexes include the main subunit alpha1, and the accessory ones, including subunit gamma that remains unexplored. Here, we demonstrate that CaV gamma subunit 4 (CaVγ4) is downregulated in islets from human donors with diabetes, diabe

Removal of metals from contaminated waters : Evaluating the use of synthetic adsorbents and green algae biomass

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

Adsorption of cadmium by a high-capacity adsorbent composed of silicate-titanate nanotubes embedded in hydrogel chitosan beads

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

Depressivity and mortality risk in a cohort of elderly men. A role of cognitive and vascular ill-health, and social participation

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

Vertical InAs/InGaAsSb/GaSb Nanowire Tunnel FETs on Si with Drain Field-Plate and EOT = 1 nm Achieving Smin= 32 mV/dec and gm/ID= 100 V-1

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

Radial migration and vertical action in N-body simulations

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

CLI-DOS : Collaborative Counteraction against Denial of Service in the Internet of Things

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
