Ambipolar conduction in gated tungsten disulphide nanotube.

Devices based on transition metal dichalcogenide nanotubes hold great potential for electronic and optoelectronic applications. Herein, the electrical transport and photoresponse characteristics of a back-gate device with a channel made of a single tungsten disulfide (WS) nanotube are investigated as functions of electric stress, ambient pressure, and illumination. As a transistor, the device exhibits p-type conduction, which can be transformed into ambipolar conduction at a high drain-source voltage.

Frequency of Group A Infection and Analysis of Antibiotic Use in Patients with Pharyngitis-A Retrospective, Multicenter Study.

is responsible for 20-30% of pharyngitis in children and 5-15% in adults. The ineffective treatment of group A Streptococcus (GAS) infections can result in postinfectious sequelae. This study aims to evaluate the frequency of GAS pharyngitis and assess the management of patients with pharyngitis and antibiotic use.

The Effect of Lower Limb Pressotherapy Treatment on Selected Rheological and Biochemical Indices of Blood in Young, Healthy Women.

Intermittent pneumatic compression is a non-invasive therapeutic technique that has been gaining popularity in recent years due to its potential use in many areas of medicine. It can be successfully used alone or in combination with other therapeutic methods. The aim of this study was to investigate whether and how a series of pressotherapy treatments on the lower limbs affects the rheological properties of blood (blood count, red blood cell deformability and aggregation, and blood viscosity), lipid profile (total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein), and renal profile (urea, creatinine, and estimated glomerular filtration rate) in young, healthy women.

Effectiveness of solution-focused brief therapy: An umbrella review of systematic reviews and meta-analyses.

Objective: This umbrella review of systematic reviews and meta-analyses evaluates the effectiveness of Solution-Focused Brief Therapy (SFBT) across various populations and settings.

Method: A total of 25 systematic reviews, including 15 meta-analyses, were analyzed. Reviews were included if they used systematic search methods and quality assessments and focused on the effectiveness of SFBT as a therapeutic approach.

Impact of genotypic variation and cultivation conditions on the techno-functional characteristics and chemical composition of 25 new Canadian quinoa cultivars.

The utilization of quinoa in food production requires comprehensive information on its processing characteristics. Twenty-five new quinoa cultivars developed by the Northern Quinoa Breeding Program, grown in three Canadian locations over two seasons, were characterized for their proximate composition, pasting properties, thermal properties, water absorption index, water solubility index, foaming capacity, foaming stability, oil holding capacity, and emulsion activity crucial for potential food applications. Results showed significant variations in the proximate composition among the cultivars, which was also influenced by the growing location and harvest year.
