VALENCE CHANGE ABILITY AND GEOMETRICAL OCCUPATION OF SUBSTITUTION... Chemical Engineering

Nanoparticles were then mixed with Vulcan carbon CX72 with a mass ratio of C:XFe2O4 = 40:60. The as-prepared C/XFe2O4 (XFe2O4 = 60 w%) material and polyvinylidene difluoride (PVDF) were mixed in a mass ratio of 90:10 and dispersed in N-methyl pyrrolidone (NMP). The resulting slurry was pasted onto n... Continue Reading

ON-CHIP NEAR-INFRARED SPECTROSCOPY OF CO₂ USING HIGH RESOLUTION P... Electrical Electronics

Carbon dioxide (CO2) is the most important greenhouse gas and the major product of combustion. Detecting CO2 is critical for many practical applications such as combustion control1 and pollution monitoring.2 Of all existing gas sensor technologies, infrared (IR) absorption is widely used as a simple...

EINSTEIN’S EQUATIONS IN THE PRESENCE OF SIGNATURE CHANGE Mathematics

INTRODUCTION Classical cosmological models containing an initial region of Euclidean signature joined to a final region with the usual Lorentzian signature were introduced by Ellis et al.1,2 A basic feature of this work is the use of the Darmois junction conditions at the surface where the signatur...

ASSESSING AND MAXIMIZING DATA QUALITY IN MACROMOLECULAR CRYSTALLO... Bio Chemistry

The quality of macromolecular crystal structures depends, in part, on the quality and quantity of the data used to produce them. Here, we review recent shifts in our understanding of how to use data quality indicators to select a high resolution cutoff that leads to the best model, and of the potent... Continue Reading

USAGE, COSTS, AND BENEFITS OF CONTINUOUS INTEGRATION IN OPEN-SOUR... Computer Science

Continuous integration (CI) systems automate the compilation, building, and testing of software. Despite CI rising as a big success story in automated software engineering, it has received almost no attention from the research community. For example, how widely is CI used in practice, and what are s... Continue Reading

THE EFFECT OF OWNERSHIP STRUCTURE ON THE PRICE EARNINGS RATIO — R... Business Administration

Prior studies document the systematic tendency for firms with low price to earnings ratios (LPE) to earn higher stock returns and firms with high price to earnings ratios (HPE) to earn lower stock returns, in both the United States and in international markets (Campbell & Shiller, 2001; Capaul, Rowl...

AN EXAMINATION OF THE SHRIMP FUTURES MARKET Marketing

Abstract. The only two seafood commodities traded in futures markets are frozen white and black tiger shrimps on the Minneapolis Grain Exchange (MGE). These two contracts, however, have failed to attract the expected trade volume based on the underlying shrimp cash market flow. First, we investiga... Continue Reading

EFFECT OF MEDIUM RANGE ORDER ON PULSED LASER CRYSTALLIZATION OF A... Mechanical Engineering

Sputter deposited amorphous Ge thin films had their nanostructure altered by irradiation with highenergy Arþ ions. The change in the structure resulted in a reduction in medium range order (MRO) characterized using fluctuation electron microscopy. The pulsed laser crystallization kinetics of the as-...

MULTISCALE EFFECTS OF INTERFACIAL POLYMER CONFINEMENT IN SILICA N... Chemical Engineering

For many natural and synthetic composite materials, enhancing or reinforcing the linear and nonlinear viscoelastic properties of polymer (elastomer) materials is accomplished by inclusion filler particles (e.g. carbon black, silica).1–4 Mechanical properties of elastomer systems can be substantial...

ENTREPRENEURIAL MOTIVES AND CHARACTERISTICS AN ANALYSIS OF SMALL... Business Administration

As Zhao and Getz (2008) observed, the tourism and hospitality sectors are generally dominated by small and family businesses worldwide. Some major contributions of these businesses include job creation, economic revitalization (Fleischer & Felsenstein, 2004; Wanhill, 2000), destination developmen... Continue Reading

HETEROAGGREGATION BETWEEN CITRATE-STABILIZED GOLD NANOPARTICLES A... Chemical Engineering

Understanding the aggregation behavior of engineered nanomaterials (ENMs) in aqueous environments is essential to understanding their fate, transport, and toxicity. Because naturally occurring colloids will likely be present at much higher concentrations than ENMs in environmental systems, heteroag... Continue Reading

ANALYSIS AND TRANSFORMATIONS IN SUPPORT OF ANDROID PRIVACY Computer Science

To protect user’s privacy and system’s integrity, mobile platforms use permission models to control accesses to protected resources such as GPS location, Contacts, etc. The previous major version of Android used a static permission model, which compromised the security and privacy of apps. Android 6... Continue Reading

DIGITAL EXCESS LOOP DELAY COMPENSATION TECHNIQUE WITH EMBEDDED TR... Electrical Electronics

Introduction: In communication systems, rapidly increasing demands on system bandwidth lead to design challenges for the analogue front end. High-speed high-performance analogue-to-digital converters thus became necessary. The continuous-time delta–sigma (ΔΣ) modulator (CT-DSM) is a good candidate d... Continue Reading

LEAF PROCESSING BEHAVIOUR IN ATTA LEAFCUTTER ANTS 90% OF LEAF CUT... Bio Chemistry

We observed and videotaped processing behaviours of our laboratory A. cephalotes colony. For ease of recording, we scooped roughly 10 cm diameter balls of comb material and the associated ants into glass-topped containers and provided them with Rubus armeniacus or Prunus lusitanica leaves. During mo... Continue Reading
