Effect of gas distributor on gas–liquid dispersion and mass transfer characteristics in stirred tank

Aiming at the fact that the function of gas distributor is often neglected in the case of high viscosity conditions, a novel spherical micro-orifice gas distributor was proposed and investigated experimentally in water system and non-Newtonian viscous system, respectively. The comparisons of gas–liquid dispersion and mass transfer performance between novel spherical micro-orifice gas distributor a

Complete Revascularization Versus Culprit Lesion Only in Patients With ST-Segment Elevation Myocardial Infarction and Multivessel Disease : A DANAMI-3–PRIMULTI Cardiac Magnetic Resonance Substudy

Objectives: The aim of this study was to evaluate the effect of fractional flow reserve (FFR)–guided revascularization compared with culprit-only percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) on infarct size, left ventricular (LV), function, LV remodeling, and the presence of nonculprit infarctions. Background: Patients with STEMI with

Prognostic value of lymphocyte-monocyte ratio at diagnosis in Hodgkin lymphoma : A meta-analysis

Background: Prognoses of most adult Hodgkin lymphoma (HL) patients are excellent; most of them can achieve permanent remission that can be considered cured. However, many are under-treated or over-treated by standard modern therapies. An accurate determination of prognosis may allow clinicians to design personalised treatment according to individual risk of disease progression and survival. Lympho

One Precursor but Two Types of Graphene Nanoribbons : On-Surface Transformations of 10,10′-Dichloro-9,9′-bianthryl on Ag(111)

On-surface synthesis has emerged in the last decade as a method to create graphene nanoribbons (GNRs) with atomic precision. The underlying premise of this bottom-up strategy is that precursor molecules undergo a well-defined sequence of inter- and intramolecular reactions, leading to the formation of a single product. As such, the structure of the GNR is encoded in the precursors. However, recent

Exploring telomere length in mother-newborn pairs in relation to exposure to multiple toxic metals and potential modifying effects by nutritional factors

Background: The uterine environment may influence telomere length at birth, which is essential for cellular function, aging, and disease susceptibility over the lifespan. However, little is known about the impact of toxic chemicals on early-life telomeres. Therefore, we assessed the potential impact of multiple toxic metals on relative telomere length (rTL) in the maternal blood, cord blood, and

Implementation of the sectional aerosol module SALSA2.0 into the PALM model system 6.0 : Model development and first evaluation

Urban pedestrian-level air quality is a result of an interplay between turbulent dispersion conditions, background concentrations, and heterogeneous local emissions of air pollutants and their transformation processes. Still, the complexity of these interactions cannot be resolved by the commonly used air quality models. By embedding the sectional aerosol module SALSA2.0 into the large-eddy simula

PCR inhibition mechanisms in forensic DNA analysis

In forensic DNA analysis, the polymerase chain reaction (PCR) enables DNAanalysis of minute biological crime scene traces. PCR is an enzymatic reaction for amplification of specific DNA fragments involving both biochemical andbiophysical processes. The main analytical challenge is posed by the nature of the samples of interest. Crime scene samples are heterogeneous and often contain background mat

Simultaneous Growth of Pure Wurtzite and Zinc Blende Nanowires

The opportunity to engineer III-V nanowires in wurtzite and zinc blende crystal structure allows for exploring properties not conventionally available in the bulk form as well as opening the opportunity for use of additional degrees of freedom in device fabrication. However, the fundamental understanding of the nature of polytypism in III-V nanowire growth is still lacking key ingredients to be ab

Measurements of Strain and Bandgap of Coherently Epitaxially Grown Wurtzite InAsP-InP Core-Shell Nanowires

We report on experimental determination of the strain and bandgap of InAsP in epitaxially grown InAsP-InP core-shell nanowires. The core-shell nanowires are grown via metal-organic vapor phase epitaxy. The as-grown nanowires are characterized by transmission electron microscopy, X-ray diffraction, micro-photoluminescence (μPL) spectroscopy, and micro-Raman (μ-Raman) spectroscopy measurements. We o

Beyond Miracle and Malaise. Social Capability in Côte d’Ivoire and Senegal during the Development Era 1930–1980

This paper investigates the outcome of the efforts to economically catch up during theso-called development era in French-speaking West Africa. An attempt is made tomeasure and discuss key elements of social capability over the period 1930–1980 inCôte d’Ivoire and Senegal following Moses Abramovitz’interpretation of socialcapability. The paper distinguishes between four elements of social capabili

Optimal Performance of Advanced Radiating Structures

Requirements on radiating structures are constantly increasing, demand for faster speed, smaller size, and higher reliability drives today's technical development. However, for electrically small structures, less than half-a-wavelength in size, performance is fundamentally limited by physical size. This thesis explores how to construct and calculate physical bounds for advanced antennas and comple

Redeeming the Canon: Transdisciplinary Collocations

The canon has been remolded under the influence of later developments in technology and media. Posthumanism and Communication and Performance Studies push forward the demythization – initiated by the Cultural Studies – of the aesthetic isolationism of the New Criticism. The new developments do not dispute the primacy of the aesthetic/truthful criteria used for informing the canon, but they disclos
