Hotel Facial Recognition Systems: Insight into Guests' System Perceptions, Congruity with Selfimage, and Anticipated Emotions

In line with novel service models, facial recognition systems are promising in hotels, as they can optimize legacy consumer tasks (e.g., authentication, payment) and increase security. Using data collected from a nationwide sample of U.S. hotel consumers, this study empirically validated a conceptual model that explains consumers’ intentions to use facial recognition systems based on system perceptions (i.e., performance and effort expectancy), congruity with self-image, trust in hotel, and positive and negative anticipated emotions. Performance expectancy, trust in organization, and positive anticipated emotions significantly influenced intentions, while congruity with self-image and effort expectancy significantly influenced performance expectancy.
SAFT1-RPM Approximation Extended to Phase Equilibria and Densities of CO2−H2O and CO2−H2O−NaCl Systems

In SAFT1-RPM approximations of CO2−H2O and CO2−H2O−NaCl systems, relevant to oil recovery and CO2 sequestration, CO2 is modeled as a molecule with three association sites, two sites of type O and one site of type C. H2O is modeled as a molecule with four association sites, two sites of type O and two sites of type H. The salt is modeled as a molecule composed of two charged, but nonassociating, spherical segments, of which one represents the cation and one represents the anion. For the CO2−H2O system, only one type of cross-association is assigned, i.e., between the site of type O in CO2 and the site of type H in H2O. Using temperature-dependent parameters, SAFT1-RPM is found to represent the density and equilibrium data for the CO2−H2O system, including the minimum H2O concentration in the CO2-rich phase in the y-P diagram. For the CO2−H2O−NaCl system, an additional binary interaction constant is used, the same for both CO2−Na+ and CO2−Cl- pairs, which is needed to correct the short-range interactions. S.
Syntheses, Characterization, and Crystal Structures of Two Tetrachlorocobaltate(II) Salts With 4-Substituted Benzyl Triphenylphosphonium

Two new salts containing tetrachlorocobaltate(II) anion, [4FBz TPP]2[CoCl4](1) and [4ClBzTPP]2[CoCl4]·3H2O(2) ([4FBzTPP]+ = 1-(4’-flurobenzyl)triphenylphosphonium; [4ClBzTPP]+ = 1-(4’-chlorobenzyl)triphenylphosphonium), have been prepared and characterized by elemental analysis, IR, UV-Vis, ESI-MS, molar conductivity, and single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system with space group P21/c, whereas 2 crystallizes in the triclinic system with space group P-1. The [CoCl4]2– anion in two salts exhibits a distorted tetrahedral coordination geometry. The C‒H···Cl, O‒H···Cl, and O‒H···O hydrogen bonds, p···π and π···π interactions, or O···O and Cl···O in 1 and 2 consolidate the crystal packing and give further rise to a 3D network structure.
Factors Affecting Entrepreneurial Student Intention in Learning Technology

In different areas, including industry and entrepreneurship, Industrial Revolution 4.0. The next generation of entrepreneurs, prospective entrepreneurs in the future, need to plan and implement technology to adapt to change. This research aims to find out what factors affect entrepreneurial students' interests and behaviour. This analysis is quantitative causality. As a grand theory we use UTAUT 2 Model. The data collection process uses primary data, which distributes questionnaires to students taking business classes. Testing hypothesis in this study uses a path analysis approach for structural equations modelling. We used statistical tools in data processing. The findings of our study show that varying results, perceptions of effort, social impact, circumstances, price values, behavioural intentions are affected. Though hedonic motivation has little effect on behavioural intent. Facilitating circumstances and behaviours often has a partly beneficial impact on the actions of usage. Conduct intent has a positive effect on the conduct of use
Nitrogen and Sulfur Effects on Macro- and Micronutrient Contents in Canola (Brassica napus L.) Grown on Acidic Soils of the Western Cape Province of South Africa

Soil pH and nutrient contents influence the uptake and utilization of nutrients required for plant growth. Soil characteristics in the canola-growing areas of the Western Cape Province of South Africa are often very variable. Hence, the major aim of this research was to determine the effects of soil and climatic differences as experienced at different localities on macro- and micronutrient contents and uptake in canola plants fertilized with different nitrogen (N) and sulfur (S) application rates. Plants fertilized with 0, 15, and 30 kg S ha−1 in combination with N rates of 0 and 90 kg ha−1 were sampled at 90 days after planting (DAP) (flowering stage) at Altona, Elsenburg, Langgewens, Roodebloem, and Welgevallen localities in the Western Cape during 2009 2010, and 2011. Nutrient content in canola plants were affected by locality and interactions between locality and N application rates. Sulfur content within the plants remained less than the sufficient quantity of 0.5%, and a dilution effect on elemental concentration in canola especially at greater N rates (plus lack of sufficient S) is apparently evident from the results. The results also reveal that canola S application should match S adsorption capacity of the low pH soils of the Western Cape.

Behavioural Intent of Indian Consumers to Accept Mobile Banking Services

Banking system around the globe is becoming digitally advanced and India, too, has adopted the digital mode to transform the payment and settlement system. The number of mobile internet users is continuously increasing owing to the easy accessibility of mobile phones and cost efficiency of their usage. Mobile banking allows the consumers to conduct the financial transactions and other banking activities using mobile phones. Mobile banking has ensured easy and rapid accessibility of banking facility 24*7 and served as a medium to reach the unbanked, thereby becoming a gateway to financial inclusion. Digital innovations are critical for achieving and sustaining an inclusive economic growth, hence, eliminating poverty. In this paper, we have applied the extended version of the Technology Acceptance Model (TAM), originally given by Davis in 1989, to study the key determinants of behavioral intent of consumers to accept mobile banking services. TAM in itself is an adaptation of the Theory of Reasoned Action (TRA) (Fishbien and Ajzen, 1975). According to TRA, the actual action of an individual is determined by his/her behavioral intention, which, in turn, is influenced by his/her attitude and subject norm. The key constructs that have been studied in this paper are perceived ease-of-use, perceived usefulness, perceived credibility, normative pressures, self-efficacy and attitude to use. In order to achieve the objective, we have adapted a five-point Likert scale questionnaire containing 20items.The behavioral intent was then regressed against these key constructs. The study attempts to trace the causality between the behavioral intent and the main key constructs of TAM.
A theoretical and experimental study of magnetism in Gd2In

We present detailed theoretical calculations and careful experiments to elucidate the magnetic properties of Gd2In. Our calculations suggest that Gd2In is a rather unique system where both localized 4f electrons as well as itinerant 5d electrons all originating from Gd are responsible for its novel magnetic properties with hardly any role of In s, p electrons. A careful analysis of the magnetization and magnetoresistance data as a function of field revealed that the magnetic behavior of Gd2In may be divided into three distinct regions. We argue with the aid of first principles electronic structure calculations that these three regions originate due to the different response of the localized 4f and itinerant 5d electrons of Gd upon application of the magnetic field. We show that in addition to the Gd 4f electrons, the Gd 5d electrons are also important for the metamagnetic behavior of Gd2In. These results establish the important role of Gd 5d electrons in the magnetic properties of Gd2In that so far only r.
Stabilization of Organic Carbon via Chemical Interactions with Fe and Al Oxides in Gley Soils

Abstract The importance of soil organic carbon (SOC) stabilization via chemical interactions with Fe and Al oxide minerals within gley soils remains unclear. Changes in the proportions of Fe/Al oxides and SOC and N contents associated with Fe/Al oxides within the profiles of gley soils under contrasting hydrological regimes and freely draining control soils from Harwood Forest (northeast England) were investigated. Sequential selective dissolution techniques were used to measure Fe/Al oxide crystallinity and explore whether crystallinity differed between gleyed and freely draining soils. Extracts were analyzed using Fourier transform infrared spectroscopy to investigate the chemical characteristics of organic matter (OM) associated with Fe/Al oxides. Strongly crystalline Fe oxides were the dominant (∼50%–80% of total Fe oxides present) mineral phase in gley mineral soils. Contrasting gley soil hydrological regimes influenced total subsoil Fe and total and weakly crystalline Al oxide concentrations. Also, within-profile changes in strongly crystalline Fe oxide concentrations were linked to differences in hydrological and redox conditions. A large proportion of SOC (generally 70%–90% of total) seemed to be associated with Fe/Al oxides. Correlation plots, however, indicated that SOC contents were not linearly related to amounts of total Fe and Al oxides, weakly crystalline Fe and Al oxides, or strongly crystalline Fe oxides. The lack of linear correlations observed for these acidic soils may be caused by contributions from other extractable soil components and factors such as high organic loadings and insufficient amounts of Fe/Al oxides for interaction with SOC in topsoils and variable surface loadings of different organic inputs at different soil depths. Subsoil C/N ratios (∼18–21) were higher than those in extracted subsoil residues (∼9–17), suggesting that minerals other than Fe/Al oxides preferentially adsorbed N-rich microbially processed compounds. The OM associated with weakly and strongly crystalline Fe/Al oxides was chemically different, the latter generally having greater hydroxyl, aliphatic, carboxylate, and /or phenolic character and less carbohydrate character than the former. This research shows that interactions between Fe/Al oxides and SOM in redox-dynamic gley soils under different hydrological regimes are complex, and further investigations of SOC stabilization in these systems using selective dissolution and other complementary techniques are required.
TEMPERATURE DEPENDENCE OF IMPACT IONIZATION IN ALGAN-GAN HETEROSTRUCTURE FIELD EFFECT TRANSISTORS

We report on the studies of the impact ionization in AlGaN–GaN heterostructure field effect transistors in the temperature range 17–43 °C. The results show that the breakdown voltage and the characteristic electrical field Ei of the impact ionization have a positive temperature coefficient. The value of Ei at room temperature is estimated to be approximately 2.6 MV/cm, which agrees with recent theoretical prediction [J. Kolnik et al., J. Appl. Phys. 82, 726 (1997)].
Rare earth oxides as nanoadditives in 3-D nanocomposite scaffolds for bone regeneration

Nanocomposite scaffolds of bioactive glass foams containing tailor made rare earth oxide (i.e. nanoceria) additives were demonstrated to enhance the production of collagen by HMSCs (Human Mesenchymal Stem Cells) compared to bioactive glass scaffolds without nanoceria. The addition of osteogenic supplements was not required for this to occur. Two different preparations of nanoceria were successfully incorporated in 3-D bioactive glass foam scaffolds and were compared with bioactive scaffolds without nanoceria. The nanoparticles had individual particle sizes of 3–5 nm while the agglomerate size varied from 5–15 nm. Preliminary investigations show that nanoceria is non toxic to the cells. After 10 days of culture, nanoceria containing scaffolds showed enhanced osteoblastic differentiation of HMSCs and collagen production compared to the scaffolds without nanoceria even in the absence of any osteogenic supplements (i.e. ascorbic acid, dexamethasone and β-glycerophosphate). This could be due to the incorporation of nanoceria, which acts as an oxygen buffer thereby regulating the differentiation of HMSCs. Further investigations are currently underway to determine the role of the nanoceria controlled oxygen buffering on the HMSC differentiation.
Crevice Corrosion of Stainless Steels: I. A Mathematical Model

AbstractA mathematical model of the initiation stage of crevice corrosion has been developed, based on the generally accepted mechanism of oxygen depletion within the crevice, followed by a pH fall and eventually permanent breakdown of the passive film and the onset of rapid corrosion. The model highlights the importance of the critical crevice solution (CCS) and the current flowing when the alloy is in the passive condition (passive current), which characterise a given alloy's resistance to crevice corrosion, the crevice geometry and the Cl− level of the bulk solution. The model predicts how the pH within the crevice falls with time until it reaches either the limiting value, as a result of mass transfer considerations, or the critical pH value which causes breakdown and the onset of rapid corrosion.Potential uses of the model lie in the areas of materials selection, setting design criteria and defining environment limitationsfor the use of given alloys.
BIOMASS, NITROGEN, SULFUR, AND PHOSPHORUS CONTENTS OF BEANS GROWN IN LIMED SOIL IN RESPONSE TO FOLIAR APPLICATION OF HNO3 OR H2SO4 MISTS

Bean plants (Phaseolus vulgaris L.) were subjected to simulated acid mist treatments (pH 4.5, 3.0, 2.3) in the greenhouse. Solutions containing either HNO3 or H2SO4 were applied as mists over a period of 31 days. The growth medium had a pHKCl of 7.9 and a calcium (Ca) content of 18.5 mg g−1. Plants were sampled at flowering and at ripening, for determination of length, fresh and dry weights of different plant organs, and number of nodules. The plant samples were analyzed for nitrogen (N), sulfur (S), and phosphorus (P) content. A significant reduction of stem growth was recorded as a result of the treatment. Some of the plants had interveinal chlorosis, indicating mild iron (Fe) or manganese (Mn) deficiency caused by the high soil pH. The lowest leaflet dry weight was 86% of the control at a dry matter content of 90% of the control. A reduction in shoot:root dry mass ratio was detected. Pod dry weight was not affected. High increases in leaflet N (145%) or S (204%) content were found, which were roughly proportional to the respective treatment levels of HNO3 or H2SO4. Phosphorus content and N:P ratio of leaflets responded to treatment levels and chemical composition of treatment solutions. The root S content was affected only slightly. Nodules were more sensitive to HNO3 treatment, which at pH 2.3 reduced the number of large nodules to 14% of the control at flowering. At ripening of the pods, the effect of treatments on nodules was less pronounced. H2SO4 treatment also reduced the nodule numbers at higher acidities of mist. Nodule numbers at different treatment levels covaried in all variants with stem height growth, shoot:root dry mass ratio and P content in pods. In HNO3 treated plants, the numbers of root nodules changed inversely to the S content in leaflets. It was concluded that an increase in S content in the plants was less than an increase in N content. The hypothesis that H2SO4 mist causes more disturbances in bean plants than HNO3 mist was not confirmed by the current experiments.
An Overview of Recent Findings on the Effect of Light on Circulation Rhythms

Light, traditionally for vision, also has non-visual effects on human physiology. Recent developments in neuroscience have demonstrated that light reaching the retina entrains the human circadian system to the natural light and dark cycle. Studies have shown that exposure to bright light during the day, particularly in the morning, may be as important as avoiding light at night for the healthy functioning of this system. This paper provides a summary of the key experimental studies which have driven understanding of this nascent subject forward. These studies are largely neuroscientific in nature, but their implications relate directly to building services engineering as the emergence of “circadian lighting” is bringing with it new metrics and standards for the environmental design of buildings. Two such metrics, Equivalent Melanopic Lux (EML) and Circadian Stimulus (CS), are examined and compared. It is shown that while care must be taken when adopting incomplete knowledge into practice, it is already becoming clear that much of our current lit environment is inadequate when seen through the lens of non-visual light.

A History of the Development and Certification of NIST Glass SRMs 610‐617

The National Bureau of Standards [NBS, now The National Institute of Standards and Technology (NIST)] certified eight glass Standard Reference Materials (SRMs) in the early 1970s. The work was undertaken jointly with Corning Glass Works and the American Society for Testing and Materials. The materials were intended to be used for calibration and control of techniques for the bulk analysis of glass only. In the absence of any CRMs designed for use in microanalysis, many laboratories are using SRMs 610-617 as though the certification included this use. This manuscript reviews the early certification effort, with attention to those aspects of the original work that have particular relevance to current use of SRMs 610-617 by microanalytical laboratories. Le Bureau National des Standards [NBS, maintenant Institut National des Standards et de la Technologie (NIST)] a certifie huit verres comme Materiaux Standards de Reference (SRMs) au debut des annees 1970. Ce travail fut entrepris conjointement avec la Societe“Corning Glass Works” et avec la “Societe Americaine des Materiaux et des Controles” (American Society for Testing and Materials). Les materiaux devaient servir uniquement a la calibration et au controle des techniques d'analyse globale de verres. En l'absence de CRM concus pour la microanalyse, de nombreux laboratoires ont utilise les SRM 610-617 comme s'ils etaient certifies pour cet usage. Ce manuscrit rappelle le premier effort de certification, en portant une attention speciale aux aspects du travail original qui relevent particulierement de l'usage maintenant courant des SRM 610-617 par les laboratoires de microanalyse.
Experimental Study of an Open-Cycle Solar Collector/Regenerator Using Liquid Desiccant For Air Conditioning

Liquid desiccant has been widely used in various solar energy applications, such as air conditioning and food drying. Especially, in the emerging solar desiccant air conditioning system, the regenerator, where the diluted solution is concentrated, plays an important role. Using the open-cycle solar collectors/regenerators (C/R) to concentrate the dilute solution is an effective way to utilize low-grade solar thermal energy to regenerate desiccant solution for air conditioning. The desiccant solution itself is a heat-collecting fluid and the regeneration process could be enhanced in this arrangement. To evaluate its thermal performance, a lab-scale experiment has been conducted using lithium bromide (LiBr) solution. The effects of ambient weather variables (solar radiation, air temperature, relative humidity) and operation conditions (air mass flow rate, solution flow rate, air inlet temperature, solution inlet temperature, and solution concentration) on the solar regeneration parallel flow configurations have been experimentally investigated. To further investigate the heat- and mass-transfer phenomenon inside the solar C/R, the heat- and mass-transfer coefficients are calculated based on the experimental data using multi-dimensional optimization method. Unlike those traditional correlations available in the literature, the effects of inlet conditions of the air and solution on the heat- and mass-transfer coefficients are clearly identified. Applying these correlations to the simulation model of the solar C/R and comparing the predicted values with the experimental values, the accuracy is satisfactory and can be applied to the further investigation for the thermodynamic performance of the solar desiccant air conditioning system.
Modeling a transport phenomena limited reactivity in short contact time catalytic partial oxidation reactors

The present paper describes a computational study of the short contact time catalytic partial oxidation of methane in fixed-bed reactors employing a rhodium-based catalyst. A monodimensional model was developed, and its validation was carried out on the basis of two experimental sets of literature data. Transport phenomena limited conditions and a local equilibrium reactivity along the catalytic bed were assumed. The last assumption provided an acceptable simplification to describe the complex microkinetic reactions taking place on the catalyst surface. The model results were satisfactorily in agreement with the measured values of conversion, product selectivity, and solid-phase temperature profiles along the fixed bed, at different space velocities and catalyst particle sizes. The numerical analysis, which allowed one to highlight the principles governing the system, also pointed out the existence of a local solid−gas temperature difference occurring within the catalytic bed. This difference dropped to z.
4-3,5-BIS(2-HYDROXYPHENYL)-1,2,4-TRIAZOL-1-YL-BENZOIC ACID : A NOVEL EFFICIENT AND SELECTIVE IRON(III) COMPLEXING AGENT

An exceptionally stable 1:2 complex [FeL2]3− is formed from the ligand H3L and FeIII. In contrast, the affinity of this ligand for other biometals is relatively small. These properties make H3L a highly promising candidate for medical applications (e.g. for the treatment of iron overload).
