Adding Value to Regional Till Geochemical Data through Exploratory Data Analysis, TREK Project Area, Central British Columbia (parts of NTS 093B, C, F, G)

Over the past 11 years, Geoscience BC has supported the continued collection and chemical analysis of till geochemical samples in efforts to promote mineral exploration throughout British Columbia (BC). The TREK (Targeting Resources through Exploration and Knowledge) project was initiated in 2013 to generate new information on BC’s northern Interior Plateau region, an area which is highly prospective for mineral resources and may also have some geothermal potential. However, the area is underexplored for these resources due to overburden of variable thickness covering complicated and poorly understood bedrock geology. Across the TREK project area almost 3000 samples were collected by the British Columbia Geological Survey (BCGS), Geological Survey of Canada (GSC) and Geoscience BC (Figure 1). Samples from the BCGS and GSC campaigns were reanalyzed as part of the TREK project (Jackaman et al., 2015) to ensure state-of-the-art data quality.
Optimization of Ionic Crosslinking Process: An Alternative to Conventional Durable Press Finishing

Cotton fiber has a natural tendency to wrinkle. In order to overcome this undesired property several durable press finishes were proposed and have been used for a long while. However, most of these chemical finishes release formaldehyde, a suspected human carcinogen, which causes fabric to lose strength and to yellow. Non-formaldehyde alternatives to these finishes are expensive. Thus, a non-formaldehyde finish prepared by using common and more available chemicals is required. In this study, we prepared anionic cotton fabric and further treated it with a novel crosslinker, namely cationic glycerin. We focused on optimizing an ionic crosslinking process in terms of the treated fabric's wrinkle recovery angle (WRA). Our results showed that high WRA results may be achieved and the strength of fabric may also be increased.
Atomic charges for variable molecular conformations

The problem of generating high-quality atomic charges valid over a range of conformations has been addressed using two related methods which both employ a constrained minimization of the difference between the quantum mechanical and classical MEP (molecular electrostatic potential) with respect to the atomic charges. The fint method involves determining the MEP and constraining the charges to reproduce the dipole at an alternative geometry. The second method involves determining the MEP for each conformation of interest and weighting the MEP for each conformation according to the appropriate Boltzmann factor
Chiral Heterobimetallic Gold(I) Ferrocenyldithiophosphonato Complexes

Chiral and non-chiral ferrocenyldithiophosphonates [tBuNH3][Fe(η5-C5H5){η5-C5H4P(OR)S2}] were prepared from [Fe(η5-C5H5){η5-C5H4PS(μ-S)}]2 and the respective alcohol ROH [R = bornyl (1), myrtenyl (2), adamantyl (3)] and tBuNH2 as base. The reaction with [AuCl(tht)] (tht = tetrahydrothiophene) gave the corresponding chiral (1a, 2a) and non-chiral (3a) heterobimetallic dimeric gold(I) ferrocenyldithiophosphonato complexes [Au{Fe(η5-C5H5)(η5-C5H4P(OR)(μ-S)2)}]2 [R = bornyl (1a), myrtenyl (2a), adamantyl (3a)]. Compounds 1–3 and 1a–3a were characterised spectroscopically (IR, 1H, 13C, 31P NMR) and by mass spectrometry, and the chiral heterobimetallic dimeric gold(I) ferrocenyldithiophosphonato complex 1a was also structurally characterised by X-ray crystallography.
Heat transport in metals irradiated by ultrashort laser pulses

Different regimes of heat propagation in metals irradiated by subpicosecond laser pulses are studied on the basis of two-temperature diffusion model. New analytical solutions for the heat conduction equation, corresponding to the different temperature dependences of the electron thermal conductivity (formula available n paper), are found. It is shown that in case of a strong electron-lattice nonequilibrium, the heat penetration depth grows linearly with time, lT varies direct as t, in opposite to the ordinary diffusionlike behavior, lT varies direct as t1/2. Moreover, the heat propagation velocity decreases with increasing laser fluence.
Investigation of Retention Behaviors of Essential Oils by Using QSRR

Genetic algorithm and multiple linear regression (GA-MLR), partial least square (GA-PLS), kernel PLS (GA-KPLS) and Levenberg-Marquardt artificial neural network (L-M ANN) technique were used to investigate the correlation between retention index (RI) and descriptors for diverse compounds in essential oils. The correlation coefficient cross validation (Q 2 ) between experimental and predicted retention index for training and test sets by GA-MLR, GA-PLS, GA-KPLS and L-M ANN was 0.948, 0.924, 0.958 and 0.980 (for training set), 0.917, 0.890, 0.915 and 0.954 (for test set), respectively. The L-M ANN model with the final optimum network architecture of [5-2-1] gave a significantly better performance than the other models. This indicates that L-M ANN can be used as an alternative modeling tool for quantitative structure-property/retention relationship (QSPR/QSRR) studies.
STUDY OF HEAT AND MASS TRANSFER DURING IR DRYING OF PAPER

ABSTRACT A mathematical model has been developed to study the drying of paper using a gas-fired IR dryer. The model accounts for various phenomena : water and vapour mass transfer, conduction, convection and radiation heat transfer. The phenomenological equations are solved with a finite difference scheme, including a modified upwind differencing scheme to account for water migration within the paper sheet. The simulation results illustrate the basic underlying phenomena involved in IR paper drying and can be instrumental to the engineer to make the detailed analyses of such a drying process. A sensitivity analysis has shown that the drying rate is most sensitive to parameters governing the IR beat transfer process whereas the paper sheet temperature is most sensitive to parameters governing the mass transfer process with the surroundings.
HYDROGEN SULFIDE PRODUCTION FROM STORED LIQUID SWINE MANURE: A LABORATORY STUDY

The production of hydrogen sulfide from stored liquid swine manure as influenced by the manure settling characteristics and the initial sulfate concentration was studied in the laboratory. The manure was settled in a 30-cm diameter ×120-cm high column for 24 h and then divided into three layers based on the solids content. The manure from different layers were placed in separate closed jars and stored for 30 days at 22 ± 2°C. The total sulfide, total solids, volatile solids, pH in the manure, and the hydrogen sulfide in the effluent gas stream were measured. The sulfide production rate was highest for all three manure layers during the first 5-10 days of storage. The top manure layer had the lowest solids content and the highest sulfide concentration. However, because of the lower pH levels in the bottom layer, the concentration of molecular H2S is higher in the bottom layer compared with the top layer. Mathematical equations for predicting hydrogen sulfide concentration and production rates in the different manure layers were derived. Three levels of initial sulfate concentration (5.89, 110, and 275 mg/L as SO4 2–) were used to test the effect of initial sulfate concentration in the liquid manure on sulfide production. Higher initial sulfate concentration in the manure resulted in higher sulfide concentration during the storage period. From the observations made, it was confirmed that reducing the sulfate concentration in the water supply would help reduce the sulfide production in the pit.
X-ray diffraction studies of freezing and melting of water confined in a mesoporous adsorbent (MCM-41)

In order to study the freezing/melting behavior of pore water, we performed x-ray diffraction measurements of water confined inside the cylindrical pores of two kinds of siliceous MCM-41 with different pore size and one kind of aluminosilicate MCM-41 as a function of temperature. The results show that its freezing/melting behavior is not affected by the incorporation of Al into the pore wall and the hysteresis effect between freezing and melting is very small or negligible. On cooling the water in the middle of the pores with a pore diameter of 4.2 nm, that is, the free water freezes abruptly around 232 K to give rise to cubic ice while the water confined in the pores with a pore diameter of 2.4 nm freezes very gradually at lower temperatures. The diffraction profile after the freezing of the free water suggests that the interfacial water confined between the surface of the pore wall and the frozen phase of the free water consists of randomly displaced water molecules.
Ab initio study of gas-phase sulphuric acid hydrates containing 1 to 3 water molecules

Sulphuric acid has a tendency to form hydrates, small clusters containing a few water molecules, in the gas phase. Hydrate formation has a stabilising effect on the vapour as the pressure of sulphuric acid drops (relative to unhydrated vapor), decreasing the nucleation rate. In classical nucleation theories the hydration energies and the hydrate distribution are predicted assuming that hydrates can be described as liquid droplets having thermodynamic properties of bulk liquid. To obtain a better understanding of the structures and formation energies of the smallest clusters, we have performed ab initio density functional calculations of the mono-,di-, and trihydrates. The hydrogen bonds between the molecules are found to be strong. The more water molecules the hydrate contains, the clearer ring-like structure is formed. Comparison to classical values for the hydration enthalpies confirms that the properties of bulk liquid do not describe the properties of the smallest clusters too well. The energy barrier.
Unipolar Diffusion Charging of Aerosol Particles at Low Pressure

Experiments of unipolar diffusion charging of ultrafine aerosol particles (10–50 nm) at low pressure (0.2–0.5 atm) were performed. Aerosol charging was achieved using a novel unipolar charger which made use of a low-intensity α-ray radioactive source. The results of the experiments were compared with numerical solutions to the fundamental equations of charging. The Fuchs' limiting-sphere charging theory in the transition regime was used for the calculation of the combination coefficients between ions and particles. Good agreement was found between experimental results and numerical predictions of the charged fraction as a function of particle diameter. This is Particle Technology Laboratory Publication No. 767.
Optimal interpolation and isarithmic mapping of soil properties. II. Block kriging.

Summary Soil properties mapped in two intensive surveys had large nugget variances, leading to large estimation variances and erratic isarithms when mapped by punctual kriging. It is likely that both surveyors and survey clients are interested in average values of soil properties over areas rather than point values, and such values can be obtained by block kriging. Estimation variances are very much smaller, and maps of sodium and stone content at Plas Gogerddan, Central Wales, kriged over blocks 920m2, and thickness of cover loam at Hole Farm, Norfolk, kriged over blocks of 400m2, are much smoother than the punctually kriged maps. The map of Hole Farm has a distinct and meaningful regional pattern.
Intelligent Induction Battery Charger for Moving Electric Vehicle Using Multiple Sources

In this paper a system is proposed to present a complete outlook for innovative charging of electric vehicle battery during running condition. Our suggested technique is used to charge their electrical car battery both while it is stationary and when it is moving. When travelling on roads, passing through toll booths takes a lot of time since the distribution transmission line cannot provide enough power rating. The primary goal is to use the inductive power transfer technology to charge the vehicle battery in an emergency. Electric methods that are wireless are only known for their low power ratings. However, our suggested approach will get around the aforementioned requirements and provide a battery charger with a high-power rating.
Investigation of the effect of heat treat-ment process on characteristics and photocatalytic activity of TiO2-UV100 nanoparticles

The effect of heat treatment process on crystallite size, phase content, surface area, band gap energy and photocatalytic activity of TiO2-UV100 nanoparticles were investigated. Heat treated TiO2 nanoparticles were characterized by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) isotherm and diffuse reflectance spectroscopy (DRS) techniques, and its photocatalytic activity was investigated in the removal of C.I. Acid Red 88 (AR88), an anionic monoazo dye of acid class, as a model contaminant. Heat treatment process at 600 °C causes an increase in crystallite size and band gap energy of TiO2-UV100 nanoparticles. The results indicate that the nanoparticles treated for 1 h at 600 °C show the highest photocatalytic activity which can effectively degrade AR88 under UVirradiation. Increasing heat treatment temperature above 600 °C led to reduction in TiO2 photoactivity which may be related to the anatase-rutile phase transformation, increasing particle size and decreasing specific surface area. Removal efficiency of AR88 with heat treated TiO2-UV100 nanoparticles was sensitive to the operational parameters such as catalyst dosage, pollutant concentration and light intensity.
Modeling the Regeneration of a Polymeric Resin Column Saturated with Ethanol by Air Purge and External Heating

In this work, the regeneration of a polymeric resin column saturated with ethanol with air purge and external heating has been studied. A theoretical model is proposed for describing the mass and heat transfers in the system, and it has been validated with experimental data. This model can be used for simulating the regeneration step in a concentration-thermal swing adsorption process for fuel-grade ethanol production. The model has been used to analyze the process dynamic behavior, and to compare the performance of the regeneration step using external heating and hot air purge.
Crystal structure of MCM-71 – a new zeolite in the mordenite group

Abstract The crystal structure of the aluminosilicate, MCM-71, was determined by a match of the powder X-ray diffraction pattern to one calculated from a theoretically predicted framework model. The unit cell contains 48 T-sites and 96 framework oxygens, where T = 41.1 Si, 6.9 Al. It crystallizes in space group Cmca, a = 7.4422(2), b = 18.5324(5), c = 19.1877(5) Å. The framework contains an elliptical 10-membered ring channel (4.3 × 6.5 Å) and an orthogonal undulating 8-membered ring channel (3.6 × 4.7 Å) to constitute a two-dimensional network of channels. Considering the aluminosilicate framework as a silicate, the crystal density is 1.77 g/cm3 and the T-site framework density is 17.8 T/1000 A3. The structure was refined against Debye-Scherrer and Bragg-Brentano powder synchrotron data by the Rietveld procedure. While non-framework oxygen atoms, consistent with water content, could be justified by TGA measurements, it was not possible to derive an accurate extra-framework model using synchrotron data from hydrated specimens. Refinement against powder data from an anhydrous specimen subsequently detected the presence of extra-framework aluminum, identified also by solid state NMR measurements.
The mechanisms of hydrolysis of the γ-lactam isatin and its derivatives

The pH dependences of the rates of hydrolysis of isatin, its N-carboxymethyl derivative and its 5-nitro substituted analogues exhibit a complex behaviour, showing a first- and second-order dependence upon hydroxide ion concentration, as well as a pH-independent pathway. The pH dependence is interpreted in terms of the formation of tetrahedral intermediates in different protonic states which may break down to products via hydroxide ion, hydronium ion and water catalysed pathways. These γ-lactams are as reactive, or more reactive, than benzylpenicillin.
Observations on the Combustion of Polymers (Plastics): From Single Particles to Groups of Particles

Abstract This investigation aimed at examining the combustion behavior of polymer particles in groups and at comparing it to that of single particles. Combustion observations were subsequently related to measurements on emissions of organic pollutants, such as PAHs and soot, which were previously measured in this laboratory under similar conditions. The following plastics (polymers), commonly found in municipal waste streams, were burned in powder form: poly(styrene) (PS), poly(ethylene) (PE), polyvinyl chloride) PVC, and poly(methyl methacry-late) (PMMA). Particles, 125-212um, were introduced to a drop-tube furnace, at steady-flow conditions, and burned in cylindrical streams (clouds), in 1250 K air. The particle mass loading in the furnace was varied to achieve either dilute clouds, where isolated (single) particle combustion occurred, or dense clouds where interactive particle combustion look place. Information on the combustion characteristics and flame temperatures of the particles was obtained by ci.
Rheological Modeling and Fracture of Hard Oxide Ceramics Modified by Ultra-Dispersed Diamond Nanoparticles

Fracture of Al-Al 2 O 3 -diamond-containing composite coating was investigated using rheological models for principal Hertzian contact of a sphere and a plate. The crystallographic and morphologic texture was characterized and the fracture resistance was measured using fracture mechanics. A rheological model of the composite coating was proposed and confirmed by in situ experiments. Examination of the composite coating showed a hardness value of 25 GPa (about 25% higher than for an alumina-based layer) and fracture resistance (about 50% higher than for a single oxide ceramic layer) as compared to prior alumina-based coatings on a soft substrate. Experiments revealed ultimate stresses and stress-strain modes of the coating. Diamond nanoparticles improved fracture resistance of an alumina-based layer. It is also thought that the composite coatings will have higher thermal conductivity and thermal shock resistance than alumina-based layers. Such physical characteristics suggest a number of possible commercial applications for the composite coatings, particularly for wear-resistant and related applications. The higher hardness and toughness of the coatings make them very attractive as substitutes for alumina-based and other ceramic-based composite coatings in these applications. composite rheology fracture stress indentation diamonds

Solubility of Carbon Dioxide and Nitrous Oxide in Water + Methyldiethanolamine and Ethanol + Methyldiethanolamine Solutions

The solubility of carbon dioxide and nitrous oxide in water + methyldiethanolamine and ethanol + methyldiethanolamine (MDEA) solutions was investigated over the whole range of amine concentrations. Experiments were performed in a reaction calorimeter at 293 K at constant atmospheric pressure. From the measurements of the solubilities of N2O in aqueous MDEA and of CO2 in pure amine, it was found that a “N2O analogy” for the prediction of CO2 solubility could not be used over the whole composition range of the aqueous MDEA solutions. In the case of ethanol + MDEA solutions, both gases show opposite trends for physical solubility as a function of amine concentration. These results disqualify the use of the “N2O analogy” in the estimation of CO2 solubility in ethanol + MDEA solutions.

This paper describes research on the prevalence, correlates, and treatment of sleep disorders in individuals with developmental disabilities. A significant number of individuals with developmental disabilities have disordered sleep, although prevalence estimates vary from 13% to 86%. Constitutional variables, including age, presence of physical and sensory impairments, and certain genetic syndromes and medical conditions appear to be related to sleep disturbance, but the evidence is mainly correlational and therefore cannot be said to show a causal relation. While a number of behavioral interventions have proven effective in the treatment of sleep disturbance, and drug therapy involving melatonin appears promising, epidemiologic work on the correlates of sleep disorders appear to have had little impact on treatment. Consideration of the nature of sleep disorders may enhance treatments for individuals with developmental disabilities. © 2001 Elsevier Science Ltd. All rights reserved.

Generation of glassy ellipsoidal particles within an elastomer by in situ polymerization, elongation at an elevated temperature, and finally cooling under strain

Le procede est applique a la polymerisation du styrene dans une matrice de poly(dimethyl siloxane) elastomere (PDMS). Les mesures de contrainte/deformation en traction des materiaux obtenus montrent que le module dans la direction parallele a celle de l'etirage est significativement superieur au module de l'elastomere PDMS/PS non etire, mais inferieur dans la direction perpendiculaire a celle de l'etirage
