Impact of AgNPs on seed germination and seedling growth : A focus study on its antibacterial potential against clavibacter michiganensis subsp. Michiganensis infection in solanum lycopersicum

This study investigated the effect of biogenic AgNPs on seed germination and seedling growth of Solanum lycopersicum. Treatment with silver nanoparticles (AgNPs) showed a significantly high germination rate and seedling growth compared to untreated seeds. Furthermore, its bactericidal effect against bacterial pathogen Clavibacter michiganensis subsp. michiganensis (cmm) infection in Solanum lycope

Graphene-based plasmonic nanocomposites for highly enhanced solar-driven photocatalytic activities

High-efficiency photocatalysts are crucial for the removal of organic pollutants and environmental sustainability. In the present work, we report on a new low-temperature hydrothermal chemical method, assisted by ultrasonication, to synthesize disruptive plasmonic ZnO/graphene/Ag/AgI nanocomposites for solar-driven photocatalysis. The plasmonic nanocomposites were investigated by a wide range of c

Block Copolymer Lithography. Applications for Sub-50 nm High-Density Nanostructures

As high technology device functionalities seem to constantly be moving towards decreasing critical dimensions and increasing density, there is a need for lithography research to move in the same direction. Block copolymer (BCP) lithography is a promising technique, which has single-digit nanometer resolution, typically has a pattern periodicity of 10-50 nm, and easily scales up the patterned area

Optimization of GaN Nanowires Reformation Process by Metalorganic Chemical Vapor Deposition for Device-Quality GaN Templates

Herein, the potential of reformed GaN nanowires (NWs) fabricated by metalorganic chemical vapor deposition (MOCVD) for device-quality low-defect density templates and low-cost alternative to bulk GaN substrates is demonstrated. The effects of epilayer thickness and NW reformation conditions on the crystalline quality and thermal conductivity of the subsequent GaN epilayers are investigated. Smooth

Epistatic effect of TLR3 and cGAS-STING-IKKε-TBK1-IFN signaling variants on colorectal cancer risk

Objective: The TLR3/cGAS-STING-IFN signaling has recently been reported to be disturbed in colorectal cancer due to deregulated expression of the genes involved. Our study aimed to investigate the influence of potential regulatory variants in these genes on the risk of sporadic colorectal cancer (CRC) in a Czech cohort of 1424 CRC patients and 1114 healthy controls. Methods: The variants in the TL

Highly Strained III-V-V Coaxial Nanowire Quantum Wells with Strong Carrier Confinement

Coaxial quantum wells (QWs) are ideal candidates for nanowire (NW) lasers, providing strong carrier confinement and allowing close matching of the cavity mode and gain medium. We report a detailed structural and optical study and the observation of lasing for a mixed group-V GaAsP NW with GaAs QWs. This system offers a number of potential advantages in comparison to previously studied common group

The benefits of collaboration : The Nordic Arthroplasty Register Association

□ The Nordic Arthroplasty Register Association (NARA) was established in 2007 by arthroplasty register representatives from Sweden, Norway and Denmark with the overall aim to improve the quality of research and thereby enhance the possibility for quality improvement with arthroplasty surgery. Finland joined the NARA collaboration in 2010. □ NARA minimal hip, knee and shoulder datasets were created

On the proper interpretation of nanofluid convective heat transfer

Technological developments of the last decades allow the production and the dispersion of particles of sizes ranging between 10 and 100 nm in liquids. In a large number of recent studies the resulting nanofluids have been reported to display anomalously high increase in convective heat transfer. The present study compiles experiments from five independent research teams investigating convective he

Pressure fluctuations of liquid-liquid slug flow in cross-junction square microchannels

Microchannels are widely used for heat transfer enhancement. The pressure characteristics are one of the most important factors affecting the heat transfer performance, and the pressure regulation may also control the heat transfer precisely in turn. As a common flow pattern of two-phase flow, slug flow has obvious advantages for heat and mass transfer, like steady flow rate and large interface ar

Seeing for understanding : Unlocking the potential of visual research in information systems

In this paper, we argue that information researchers should use images as a source of data. The information systems field is overwhelmingly visual in nature. Not only is the Internet crammed with images, but also almost every detail observed during fieldwork in different research settings can be captured in the form of digital images. Yet, we rarely engage with those images. Except for sporadic vi

Healthy Vascular Ageing and Early Vascular Ageing

Chronological age is an important independent predictor of cardiovascular events. Although the cumulative effect of cardiovascular risk factors over time partly explains this relationship, accumulating evidence suggests this is a simplistic interpretation of a more complex concept. With advancing age slowly progressive changes can be seen affecting the structure and function of large and small ves

The Association Between HIV Diagnosis Disclosure and Adherence to Anti-retroviral Therapy among Adolescents Living with HIV in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

IntroductionNine in ten of the world’s 1.74 million adolescents living with human immunodeficiency virus (ALHIV) live in Sub-Saharan Africa. Suboptimal adherence to antiretroviral therapy (ART) and poor viral suppression are important problems among adolescents. To guide intervention efforts in this regard, this review presented pooled estimates on the prevalence of adherence and how it is affecte

Acute and Long-Term Changes in Blood-Borne Biomarkers in Response to Dynamic Standing in Nonambulant Children With Cerebral Palsy

PURPOSE: To investigate acute and long-term changes in hormonal and inflammatory biomarkers in nonambulant children with cerebral palsy in response to dynamic standing exercise.METHODS: Fourteen children with severe cerebral palsy were recruited. Anthropometrics and body composition measures were obtained. Physical activity levels before the study were assessed using hip-worn accelerometry. All ch

(When) Is it Worth Investing in the Personal Service Encounter?

Many retail chains believe that the personal service encounter is the solution to declining sales figures. Via a large-scale study of Swedish fashion consumers, we demonstrate, that this may not necessarily be the case. We argue that retailers can potentially save money and convert more customers by providing a more automated journey, which includes self-service technologies, for some customers, a

Non-typeable Haemophilus influenzae major outer membrane protein P5 contributes to bacterial membrane stability, and affects the membrane protein composition crucial for interactions with the human host

Non-typeable Haemophilus influenzae (NTHi) is a Gram-negative human pathogen that causes a wide range of airway diseases. NTHi has a plethora of mechanisms to colonize while evading the host immune system for the establishment of infection. We previously showed that the outer membrane protein P5 contributes to bacterial serum resistance by the recruitment of complement regulators. Here, we report

Life is pain : Fibromyalgia as a nexus of multiple liability distributions

Fibromyalgia is a complex disease of unclear etiology that is complicated by difficulties in diagnosis, treatment, and clinical heterogeneity. To clarify this etiology, healthcare-based data are leveraged to assess the influences on fibromyalgia in several domains. Prevalence is less than 1% of females in our population register data, and about 1/10th that in males. Fibromyalgia often presents wit

KEAP1 polymorphisms and neurodevelopmental outcomes in children with exposure to prenatal MeHg from the Seychelles Child Development Study Nutrition Cohort 2

BACKGROUND: Humans differ in the metabolism of the neurotoxicant methyl mercury (MeHg). This variation may be partially due to variation in genes encoding the transcription factor Nuclear factor E2-related factor 2 (NRF2) and its negative regulator Kelch-like ECH-Associated Protein 1 (KEAP1), which regulate glutathione and related transporter and antioxidant proteins that play a role in the metabo
