Nanostructured Lipid-Based Films for Substrate-Mediated Applications in Biotechnology

Amphiphilic in nature, lipids spontaneously self-assemble into a range of nanostructures in the presence of water. Among lipid self-assembled structures, liposomes and supported lipid bilayers have long held scientific interest for their main applications in drug delivery and plasma membrane models, respectively. In contrast, lipid-based multilayered membranes on solid supports only recently begin

Mechanical properties of superhard boron subnitride B13N2

Microstructure and mechanical properties of bulk polycrystalline rhombohedral boron sub-nitride B13N2 synthesized by crystallization from the B–BN melt at 7 GPa have been systematically studied by micro- and nanoindentation, atomic force microscopy and scanning electron microscopy. The obtained data on hardness, elastic properties and fracture toughness clearly indicate that B13N2 belongs to a fam

Narratives of biorefinery innovation for the bioeconomy – Conflict, consensus, or confusion?

Transition narratives are stories promoting particular pathways for development, promoting specific actions, strategies, and interventions to enable certain outcomes in socio-technical transitions. Narratives centered around biorefineries take a significant role in the growing bioeconomy discourse, yet they express remarkably different visions for the transition. The paper uses Q methodology to id

Pool Boiling Heat Transfer of Water on Copper Surfaces With Nanoparticles Coating

Saturated pool boiling heat transfer is investigated experimentally on a copper substrate with copper nanoparticle coatings at atmospheric pressure, in terms of critical heat flux (CHF) and heat transfer coefficient (HTC). Experiments are carried out on the substrate surface with a diameter of 12 mm using DI water as the working fluid. The coating is formed by stacking copper nanoparticles generat

Co-branding public place brands : towards an alternative approach to place branding

Contrary to the traditional understanding of place branding inspired by product, service and corporation branding, the present paper adopts place branding interdisciplinary literature in order to develop a conceptual framework that focuses on the constituting features of place brands as a form of public brands. The paper suggests the way place brands are constituted is via a co-branded complex and

Direction of actin flow dictates integrin LFA-1 orientation during leukocyte migration

Integrin αβ heterodimer cell surface receptors mediate adhesive interactions that provide traction for cell migration. Here, we test whether the integrin, when engaged to an extracellular ligand and the cytoskeleton, adopts a specific orientation dictated by the direction of actin flow on the surface of migrating cells. We insert GFP into the rigid, ligand-binding head of the integrin, model with

Sourcing Trends Predictions - An Analysis of Regions and Strategies

This paper aims to highlight historical trends regarding information systems (IS) sourcing, as well as glimpsing into the subject's future. Depending on economic growth, industrialization and changes in the political climate, certain countries have become either less or more attractive as destination countries for IS sourcing. As outsourcing strategies becomes more mature, especially in the IS sec

Differences in ERP Value between Iberian Manufacturing and Services SMEs

Enterprise Resource Planning (ERP) system literature reports little research on the specificities of an industry analysis. Based on a theoretical model we assess ERP Value between Manufacturing and Services industries in Small and Medium Enterprises (SMEs) across the Iberian region (Portugal and Spain). The empirical test was conducted through structural equation modeling, using data from 261 firm

MERLIN : A French-German space lidar mission dedicated to atmospheric methane

The MEthane Remote sensing Lidar missioN (MERLIN) aims at demonstrating the spaceborne active measurement of atmospheric methane, a potent greenhouse gas, based on an Integrated Path Differential Absorption (IPDA) nadir-viewing LIght Detecting and Ranging (Lidar) instrument. MERLIN is a joint French and German space mission, with a launch currently scheduled for the timeframe 2021/22. The German S

What is a “unimodal” cell population? Using statistical tests as criteria for unimodality in automated gating and quality control

Many automated gating algorithms for flow cytometry data are based on the concept of unimodal cell populations. However, in this article, we show that criteria previously used to make decisions on unimodality cannot adequately distinguish unimodal from bimodal densities. We show that dip and bandwidth tests for unimodality, taken from the statistics literature, can do this with consistent and low

Plasmon-exciton coupling of monolayer MoS2-Ag nanoparticles hybrids for surface catalytic reaction

The optical properties of monolayer molybdenum disulfide (MoS2)/Ag nanoparticle (NP) hybrids and their application to surface catalytic reactions were studied by transmission, photoluminescence (PL) and Raman spectroscopies. The local surface plasmon resonance (LSPR) of Ag nanoparticles was tuned to better match the exciton energy of monolayer MoS2. The PL of the hybrids was enhanced by more than

Anguiform graffiti in the Roman quarries at Gebel el Silsila

The current issue of Journal of Intercultural and Interdisciplinary Archaeology is mainly dedicated to the various aspects of Renenutet/Isis Thermouthis, but also snake-like deities, their iconography and associated apotropaia. This paper will explore three main topics associated with this topic within the sandstone quarry of Gebel el Silsila: 1) Graeco-Roman anguiform pictorial representations, 2

From Epipalaeolithic petroglyphs to Roman graffiti : Stylistic variability of anthropomorphs at Gebel el Silsila (Upper Egypt)

Gebel el-Silsila displays an astounding concentration of incised illustrations, of which anthropomorphic figures are frequent motifs. These figures were produced over several millennia; from prehistoric petroglyphs to pictorial graffiti of dynastic periods and throughout into Roman days. Spanning over six millennia visitors to Gebel el Silsila depicted huntsmen, warriors, boatmen, and horsemen, reGebel el Silsila displays an astounding concentration of incised illustrations, of which anthropomorphic figures are frequent motifs.
