DNS STUDY OF DEPENDENCE OF BULK CONSUMPTION VELOCITY ON TURBULENCE AND MIXTURE CHARACTERISTICS

A 3D Direct Numerical Simulation (DNS) study of propagation of a single-reaction wave in statistically stationary, homogeneous, isotropic, and constant-density turbulence was performed in order to evaluate both developing U_T^t and fully developed U_T^s bulk turbulent consumption velocities by independently varying a ratio 0.5≤u'⁄S_L ≤90 of the rms turbulent velocity to the laminar wave speed, a r

DNS STUDY OF ROLE PLAYED BY MOLECULAR TRANSPORT IN BENDING EFFECT

A DNS study of propagation of either an infinitely thin passive interface or a reaction wave of a nonzero thickness in forced, constant-density, statistically stationary, homogeneous, isotropic turbulence was performed by solving Navier-Stokes equations and either level set or reaction-diffusion equation, respectively, with all other things being equal. The simulations covered a wide range of cond

The relevance of structural features of cellulose and its interactions to dissolution, regeneration, gelation and plasticization phenomena

Cellulose is the most abundant polymer and a very important renewable resource. Since cellulose cannot be shaped by melting, a major route for its use for novel materials, new chemical compounds and renewable energy must go via the solution state. Investigations during several decades have led to the identification of several solvents of notably different character. The mechanisms of dissolution i

Comparison of milk protein composition and rennet coagulation properties in native Swedish dairy cow breeds and high-yielding Swedish Red cows

Recent studies have reported a very high frequency of noncoagulating milk in Swedish Red cows. The underlying factors are not fully understood. In this study, we explored rennet-induced coagulation properties and relative protein profiles in milk from native Swedish Mountain and Swedish Red Polled cows and compared them with a subset of noncoagulating (NC) and well-coagulating (WC) milk samples fr

Convergence, Continuity and Recurrence in Dynamic Epistemic Logic

The paper analyzes dynamic epistemic logic from a topological perspective. The main contribution consists of a framework in which dynamic epistemic logic satisfies the requirements for being a topological dynamical system thus interfacing discrete dynamic logics with continuous mappings of dynamical systems. The setting is based on a notion of logical convergence, demonstratively equivalent with c

Supported fluid lipid bilayer as a scaffold to direct assembly of RNA nanostructures

RNA architectonics offers the possibility to design and assemble RNA into specific shapes, such as nanoscale 3D solids or nanogrids. Combining the minute size of these programmable shapes with precise positioning on a surface further enhances their potential as building blocks in nanotechnology and nanomedicine. Here we describe a bottom-up approach to direct the arrangement of nucleic acid nanost

Compact Full Duplex MIMO Radios in D2D Underlaid Cellular Networks : From System Design to Prototype Results

This paper considers the implementation and application possibilities of a compact full duplex multiple-input multiple-output (MIMO) architecture, where direct communication exists between users, e.g., device-to-device (D2D) and cellular link coexisting on the same spectrum. For the architecture of the compact full duplex radio, we combine an analog self-interference canceler-based dual polarizati

Detailed characterization of particulate matter in alcohol exhaust emissions

A way to reduce net CO2 emission and circumvent the high particle emissions from compression ignition (CI) engines, while retaining high efficiency, is by utilizing lighter alcohols in the partially premixed combustion (PPC) process. Methanol and ethanol have a very short carbon chain, and form less soot/particulate matter (PM) during combustion compared to diesel fuel. This study analyzes and com

The effects of ocean SST dipole on Mongolian summer rainfall

Cross-correlations between inter-annual summer rainfall time series (June to August: JJA) for arid Mongolia and global sea surface temperatures (GSST) were calculated for prediction purposes. Prediction of summer rainfall for four vegetation zones, Desert Steppe (DS), Steppe (ST), Forest Steppe (FS), and High Mountain (HM) using GSSTs for time lags of 5, 6, and 7 months prior to JJA rainfall was e

Membrane interactions and antimicrobial effects of layered double hydroxide nanoparticles

Membrane interactions are critical for the successful use of inorganic nanoparticles as antimicrobial agents and as carriers of, or co-actives with, antimicrobial peptides (AMPs). In order to contribute to an increased understanding of these, we here investigate effects of particle size (42-208 nm) on layered double hydroxide (LDH) interactions with both bacteria-mimicking and mammalian-mimicking

Chemical communication, sexual selection, and introgression in wall lizards

Divergence in communication systems should influence the likelihood that individuals from different lineages interbreed, and consequently shape the direction and rate of hybridization. Here, we studied the role of chemical communication in hybridization, and its contribution to asymmetric and sexually selected introgression between two lineages of the common wall lizard (Podarcis muralis). Males o

8.0% Efficient All-Polymer Solar Cells with High Photovoltage of 1.1 V and Internal Quantum Efficiency near Unity

In very recent years, growing efforts have been devoted to the development of all-polymer solar cells (all-PSCs). One of the advantages of all-PSCs over the fullerene-based PSCs is the versatile design of both donor and acceptor polymers which allows the optimization of energy levels to maximize the open-circuit voltage (Voc). However, there is no successful example of all-PSCs with both high Voc

Polymorphisms in manganese transporters show developmental stage and sex specific associations with manganese concentrations in primary teeth

Background: Manganese (Mn) is an essential metal that can become neurotoxic at elevated levels with negative consequences on neurodevelopment. We have evaluated the influence of single nucleotide polymorphisms (SNPs) in Mn transporter genes SLC30A10 and SLC39A8 on Mn concentrations in dentine, a validated biomarker that reflects Mn tissue concentrations early in life. Methods: The study included 1

The influence of lifestyle on airborne particle surface area doses received by different Western populations

In the present study, the daily dose in terms of particle surface area received by citizens living in five cities in Western countries, characterized by different lifestyle, culture, climate and built-up environment, was evaluated and compared. For this purpose, the exposure to sub-micron particle concentration levels of the population living in Barcelona (Spain), Cassino (Italy), Guilford (United

The impact of society on management control systems

The aim of this study is to investigate whether certain configurations of management controls dominate in certain societies (socio-cultural contexts) and whether the effectiveness of a given archetype of management control systems (MCSs) varies depending on the socio-cultural setting-the society-in which it operates. The study focuses on three socio-cultural groups and the corresponding institutio

Firefighter fatalities in Sweden, 1937 - 2016

The purpose of this work was to present collective data on firefighter fatalities in Sweden between 1937 and 2016. Data presented is directly related to operations only. Fatalities due to long-term exposure of gases, particles, and physical/psychological stress or similar were not included in the study. Also, accidents involving ambulances as well as fatalities in direct relation to physical trainThe purpose of this work was to present collective data on firefighter fatalities in Sweden between 1937 and 2016.

Technologies for the control of heat and light in the Vézère valley Aurignacian

We can trace the beginnings of our knowledge of early Upper Paleolithic (Aurignacian) use of fire to the pioneering 1910–1911 excavations at Abri Blanchard undertaken by Louis Didon and Marcel Castanet. At Blanchard, the excavators recognized and described fire structures that correspond in many ways to features excavated more recently in Western and Central Europe. Here, we address the issue of h
