Genetic diversity and identification of palearctic black flies in the subgenus wilhelmia (Diptera: Simuliidae)

Accurate species identifications are the essential first step in understanding the medical, economic, and ecological importance of black flies. The utility of DNA barcoding based on cytochrome c oxidase subunit 1 (COI) sequences was evaluated for identifying six common species of Palearctic black flies in the subgenus Wilhelmia, including several that are virulent pests. Chromosomally identified l

Acoustofluidic hematocrit determination

Hematocrit (HCT) measurements of blood from patients, blood donors and athletes are routinely performed on a daily basis. These measurements are often performed in centralized hospital labs by whole blood analyzers, which leads to long time-to-result. On site measurements, based on centrifugation can be done, but these assays require manual handling, are slow and can just measure HCT in contrast t

Stiffness optimization of non-linear elastic structures

This paper revisits stiffness optimization of non-linear elastic structures. Due to the non-linearity, several possible stiffness measures can be identified and in this work conventional compliance, i.e. secant stiffness designs are compared to tangent stiffness designs. The optimization problem is solved by the method of moving asymptotes and the sensitivities are calculated using the adjoint met

Molecularly imprinted TiO2 photocatalysts for degradation of diclofenac in water

In order to improve the selectivity in photocatalytic process, molecularly imprinted photocatalysts containing a low loading of TiO2 (from 6.6 to 16.6% of total mass) were prepared for photocatalytic degradation of an organic pollutant, diclofenac (DIC). The photocatalytic component TiO2 (P25), with and without being doped with Cu2O, was embedded in diclofenac-imprinted polymers. The molecularly i

Envisioned, enacted & stated practices: ‘Creativity’/’innovation’ and the social-political ecosystem of teaching

Ethnographic (and other) studies on teachers often rely on two kinds of material: observations of teaching practices in the classroom; and statements about teaching practices, extracted both from involved actors (e.g. teacher interviews) and from documents (e.g. educational policy documents or teaching manuals). Many scholars agree that there is a discrepancy between what is stated, or desired, pr

Carbonaceous biosignatures of the earliest putative macroscopic multicellular eukaryotes from 1630 Ma Tuanshanzi Formation, north China

The Paleo- and Mesoproterozoic fossil record of multicellular eukaryotes is scarce but extremely important in studying the evolution of life in the Precambrian Era. Typically, fossils heralded as ‘multicellular eukaryotes’ that are older than the Ediacaran are met with controversy. To confront such debates, we investigate the chemical, isotopic, and molecular structural characteristics of organic

Search for new phenomena in high-mass diphoton final states using 37 fb−1 of proton–proton collisions collected at s=13 TeV with the ATLAS detector

Searches for new phenomena in high-mass diphoton final states with the ATLAS experiment at the LHC are presented. The analysis is based on pp collision data corresponding to an integrated luminosity of 36.7 fb−1 at a centre-of-mass energy s=13 TeV recorded in 2015 and 2016. Searches are performed for resonances with spin 0, as predicted by theories with an extended Higgs sector, and for resonances

The Effect of Paid Vacation on Health: Evidence from Sweden

This study estimates the causal effect of receiving additional paid vacation days on health. Using register data on the universe of central government employees in Sweden, I exploit an age-based rule stipulated in the collective agreement covering these employees. Identification is achieved by combining a regression discontinuity with a difference-in-differences design to control for time-invarian

Modernization, formal social control, and anomie: A 45-society multilevel analysis

This article investigates how economic modernization affects normative regulation by spurring formal social control in the political, economic, and private spheres as well as anomie. Multilevel negative binomial regression modeling, using World Values Survey and country-level data from 2005, predicts individual-level anomie using country-level formal-social-control indicators as well as individual

Association between HbA1c and peripheral neuropathy in a 10-year follow-up study of people with normal glucose tolerance, impaired glucose tolerance and Type 2 diabetes

Aims: To explore the association between HbA1c and sural nerve function in a group of people with normal glucose tolerance, impaired glucose tolerance or Type 2 diabetes. Methods: We conducted a 10-year follow-up study in 87 out of an original 119 participants. At study commencement (2004), 64 men and 55 women (mean age 61.1 years) with normal glucose tolerance (n=39), impaired glucose tolerance (

Experimental study of hydrogen addition effects on a swirl-stabilized methane-air flame

The effects of H2 addition on a premixed methane-air flame was studied experimentally with a swirl-stabilized gas turbine model combustor. Experiments with 0%, 25%, and 50% H2 molar fraction in the fuel mixture were conducted under atmospheric pressure. The primary objectives are to study the impacts of H2 addition on flame lean blowout (LBO) limits, flame shapes and anchored locations, flow field

Event Based Control

In spite of the success of traditional sampled-data theory in computer control it has some disadvantages particularly for distributed, asynchronous, and multi-rate system. Event based sampling is an alternative which is explored in this paper. A simple example illustrates the differences between periodic and event based sampling. The architecture of a general structure for event based control is p

Severity and multiplicity of microvascular complications are associated with QT interval prolongation in patients with type 2 diabetes

AIMS/INTRODUCTION: A prolonged QT interval plays a causal role in life-threatening arrhythmia and becomes a risk factor for sudden cardiac death. Here, we assessed the association between microvascular complications and the QT interval in patients with type 2 diabetes.MATERIALS AND METHODS: Patients with type 2 diabetes (n = 219) admitted to our hospital for glycemic control were enrolled.
