Modeling of Limestone Dissolution for Flue Gas Desulfurization with Novel Implications

Solid-liquid dissolution is a central step in many industrial applications such as pharmaceutical, process engineering, and pollution control. Accurate mathematical models are proposed to improve reactor design and process operations. Analytical methods are significantly beneficial in the case of iterative methods used within experimental investigations. In the present study, a detailed analytical solution for the general case of solid particles dissolving in multiphase chemical reaction systems is presented. In this model, the authors consider a formulation that considers the particles’ shape factor. The general case presented could be utilized within different problems of multiphase flows. These methods could be extended to different cases within the chemical engineering area. Examples are illustrated here in relation to limestone dissolution taking place within the Wet Flue Gas Desulfurization process, where calcium carbonate is dissolving in an acidic environment. The method is the most common used technology to abate SO2 released by fuel combustion. Limestone dissolution plays a major role in the process. Nevertheless, there is a need for improvements in the optimization of the WFGD process for scale-up purposes. The mathematical model has been tested by comparison with experimental data from several mild acidic dissolution assays of sedimentary and metamorphic limestone. We have found that R2 ⊂ 0.92 ± 0.06 from dozens of experiments. This fact verifies the model qualifications in capturing the main drivers of the system.
An Integrated Model of CSR Perception and TAM on Intention to Adopt Mobile Banking

The purpose of this paper is to (1) evaluate a proposed conceptual model based on integrated Technology Acceptance Model (TAM) and Corporate Social Responsibility (CSR); (2) compare the differences between Vietnam and South Korea regarding the effects of consumer perception of CSR activities and technology acceptance on intention to adopt mobile banking. Structural Equation Modeling (SEM) was conducted to analyze the data collected from the field survey questionnaires administered to a convenience sample of Vietnamese and Korean banking customers. The results showed that there is a difference between South Korea and Vietnam with regard to intention to use mobile banking services. While the effects of social responsibility and environmental responsibility on trust, trust on perceived usefulness, perceived risk on intention to use, perceived usefulness on intention to use were significant in the context of Vietnam but those effects were not significant in South Korea. Therefore, this study has attempted to fill this gap by empirically examining some of the important factors influencing the adoption of m-banking from the Vietnamese and Korean customers’ perspectives. Finally, practical and theoretical implications for both banks and researchers in the mbanking context are also discussed in the concluding section.

Optical isolation of spectral lines emitted by sputtered tungsten in a weakly magnetized plasma

Optical isolation of the clockwise or the counter-clockwise circular polarization of spectral lines was applied to emission of sputtered tungsten atoms. As a result one measures the weak magnetic field at plasma-surface interface resulting in splitting of spectral lines (W I at 4008.751 Å and 4982.593 Å) being negligibly small with respect to the Doppler broadening. One relies only on the phase rotation of a reflected circular polarized light propagating at the normal incidence to the mirror-like surface. The spectral shift of the signal from sputtered W atoms on the detector using high-resolution spectrometer provides the value of the magnetic field at a known dispersion, i.e. no further modeling or additional assumption on the distribution of atoms is required. The isolation of spectral line components is equivalent to isolation of the effect of the magnetic field from the measured line shape. It is complete for Zeeman triplet lines and partial for other lines. The results are found to be in a very good agreement of 3% with calculations and the Zeeman resolved laser absorption spectroscopy (10%) on metastable levels of Ar I atoms.
Zinc allocation to and within Arabidopsis halleri seeds: Different strategies of metal homeostasis in accessions under divergent selection pressure

Abstract Vegetative tissues of metal(loid)‐hyperaccumulating plants are widely used to study plant metal homeostasis and adaptation to metalliferous soils, but little is known about these mechanisms in their seeds. We explored essential element allocation to Arabidopsis halleri seeds, a species that faces a particular trade‐off between meeting nutrient requirements and minimizing toxicity risks. Combining advanced elemental mapping (micro‐particle induced X‐ray emission) with chemical analyses of plant and soil material, we investigated natural variation in Zn allocation to A. halleri seeds from non‐metalliferous and metalliferous locations. We also assessed the tissue‐level distribution and concentration of other nutrients to identify possible disorders in seed homeostasis. Unexpectedly, the highest Zn concentration was found in seeds of a non‐metalliferous lowland location, whereas concentrations were relatively low in all other seed samples—including metallicolous ones. The abundance of other nutrients in seeds was unaffected by metalliferous site conditions. Our findings depict contrasting strategies of Zn allocation to A. halleri seeds: increased delivery at lowland non‐metalliferous locations (a likely natural selection toward enhanced Zn‐hyperaccumulation in vegetative tissues) versus limited translocation at metalliferous sites where external Zn concentrations are toxic for non‐tolerant plants. Both strategies are worth exploring further to resolve metal homeostasis mechanisms and their effects on seed development and nutrition.
Ownership Structure, Earnings Manipulation, and Organizational Performance: The Case of Jordanian Insurance Organizations

This study aims to investigate the direct relationship between ownership structure, earnings manipulation, and organizational performance, and then examine the mediating effect of earnings manipulation in the relationship between ownership structure and organizational performance. This study collected and analyzed secondary data published in financial reports related to all insurance organizations listed in the Jordanian market during the study period (from 2009 until 2018). A panel data analysis was conducted, giving a total of 200 observations. The findings of this study concluded that ownership concentration, foreign ownership, and organization size affect organizational performance proxied by ROA, ROE, and EPS, more specifically, ownership concentration and organization size have a positive effect, whereas foreign ownership has a negative effect. At the same time, board of director ownership, organizational ownership, and CEO compensation did not affect organizational performance. Next, the board of director ownership, ownership concentration, foreign ownership, and CEO compensation affect earnings manipulation separately. In addition, earnings manipulation positively affects organizational performance proxied by ROA, ROE and EPS. This means that the higher the earnings manipulation is, the higher the organizational performance is. Finally, earnings manipulation mediates the relationship between ownership concentration and foreign ownership of ownership structure, and organizational performance.
Prediction of Retail Beef Yield Using Parameters Based on Korean Beef Carcass Grading Standards

Two sets of data on carcass traits and beef cut parameters were used to investigate the relationships between carcass and beef cut measurements, which can be used to make predictions of retail cut percentages. One set had a total of 1,141 measurements of Hanwoo cattle of three different sex origins, which were slaughtered in an abattoir located at the National Institute of Animal Science, RDA, Korea from 1996 to 2008. To develop prediction models for retail cut percentage with higher accuracies than the current model, another set consisting of a total of 13,389 records of carcass and beef cut traits were collected from 30 abattoirs and butcheries in Korea from 2008 to 2009. Bulls yielded heavier and leaner carcasses than steers. High correlation coefficients were estimated between amount of body fat and percent retail cut (-0.82) as well as between back fat thickness (BF) and percent retail cut (-0.62). The amount of retail cut, however, was highly correlated with body weight before slaughter (BW, 0.95) or with cold carcass weight (CWT, 0.94). Relationships between percent retail cut and measurable beef yield traits, BF, loin eye area (LEA) or CWT varied by sex class, which must be considered for development of a prediction model with high accuracy. Models of data for all breeds and sexes fit the effects of breed, sex, and interaction of abattoir by butchers, whereas models of data for each breed and sex fit the effect of interaction of abattoir by butcher only. Due to possible future changes in back fat control, we performed a log transformation of BF. Our new models fit better than the currently used model.
Disability in Protracted Benign Paroxysmal Positional Vertigo at One Month from Symptom Onset- a Questionnaire Survey

Objectives: The purpose of this study was to assess the disability of patients with Benign Paroxysmal Positional Vertigo (BPPV) at one month from symptom onset. Methods: This was a cross-sectional study conducted at multiple institutions. One hundred and seventeen BPPV patients at one month from symptom onset were included (32 male, 85 female; mean age 67.7 years). After answering whether their symptoms were cured or persistent, patients completed 3 questionnaires: the Dizziness Handicap Inventory (DHI), The Vertigo Symptom Scale-Short Form (VSS-sf) to assess the frequency of vestibular and autonomic symptoms, and the Hospital Anxiety and Depression Scale (HADS). The presence of nystagmus and type of BPPV were also checked. and 62 (53.0%) reported persistent symptoms (protracted). Among the protracted patients, 44 (71.0%) patients had positional/positioning nystagmus while 18 (29.0%) patients did not. The protracted patients with nystagmus showed significantly higher DHI scores in total, physical and functional components compared with the cured patients (p<0.05). The protracted patients without nystagmus showed significantly higher DHI scores in physical components than the cured patients (p<0.05). The protracted patients with/without nystagmus showed significantly higher vestibular symptoms scores in VSS-sf and depressive scores in HADS in comparison with the cured patients (p<0.05). Conclusion: About a half of BPPV patients continue to have dizziness at one month from symptom onset. These patients have higher levels of disability in daily life and feelings of depression.
Denture hygiene among inhabitants of the Lublin province

Objectives. Dentures, like the patient’s own teeth, require the necessary hygienic procedures to keep them in good condition. The aim of the study was to analyze selected sociodemographic features, as well as awareness and hygiene behaviours in patients from the Lublin province who use fixed and removable dentures. Materials and method. The cross-sectional study material consisted of 1,200 questionnaires distributed among people residing in the Lublin province using removable or fixed dentures. The study was conducted between June 2016 – June 2017 in randomly selected private dental offices providing private and National Health Fund dental services in the Lublin province to patients using dentures. Results. The majority of respondents (51.6%) disinfected their dentures, with women more often than men providing a positive answer. Almost a half (45.6%) of respondents used dentures 24 hours a day, 36.7% stored their dentures overnight in a container with liquid, 16.3% stored them in a dry container, and others (1.4%) in a different way. A manual toothbrush was indicated by 68.3% of respondents as the method they used for daily oral hygiene. Men significantly more often used other types of brushes (electric or sonic) than women. Men also more often used dental floss. Conclusions. The dentist issuing denture should provide the patient with detailed recommendations regarding its use and proper hygiene because patients’ knowledge on this subject is insufficient.
Rheological-layered basin under strike-slip deformation: analogue approach at crustal scale

In sedimentary basins, sediment type and deposit and burial conditions generate suc-cessive layers with various rheologies reacting di ﬀ erently to boundary stresses. We used analogue modelling to explore how a rheological-layered basin reacts to strike-slip displacements applied to boundaries. Several experimental set-ups were tested by varying horizontal rheological layering (alternatingviscousandcohesivelayers)anddisplacementrates.Allexperimentsgeneratedacomplex three-dimensional deformation pattern localized into a narrow vertical band with thickened, thinned and folded domains alternating along both strike and depth. This results in a succession of positive and negative ﬂower structures connected to the basal velocity discontinuity at depth and in a decoupling of deformation from one layer to another. Thinning and thickening variations display an along-strikewavelengthproportionaltothelayerthickness,anamplitudecontrolledbyrheologicallayering, and in particular the strength contrast between each layer. The simultaneous genesis of shortening and stretching structures during only one deformation stage is symptomatic of strike-slip boundary conditions. These results indicate that caution should be exercised when postulating polyphased deformation from overprinting of di ﬀ erent deformation styles. horizontale (alternance de couches visqueuses et cohésives) et quantité de déplacement. Toutes les expériences montrent une déformation complexe localisée dans un couloir vertical étroit, formée par une succession de structures en ﬂeur positives et négatives connectées à la base du modèle. Les niveaux présentent des variations dépaisseur (zones épaissies, amincies et ployées). Les variations de style de déformation se produisent à chaque interface qui découple la déformation d’une couche à l’autre. Les variations d’épaisseur d’un niveau présentent une longueur d’onde proportionnelle à l’épaisseur de la couche dont l’amplitude est contrôlée par la stratiﬁcation rhéologique, et en parti-culier le contraste de résistance entre chaque niveau. La co-existence des structures en raccourcisse-ment et en étirement pendant la même phase de déformation sont caractéristiques des conditions aux limites décrochantes. Ce résultat remet en cause l’interprétation systématique d’une déformation polyphasée, la présence de structures accommodant de déformation di ﬀ érentes.
Results-oriented Culture and Organizational Performance: The Mediating Role of Financial Accountability in Public Sector Organizations in Vietnam

ABSTRACT Drawing on New Public Management (NPM) theory, this study examines the mediating role of financial accountability in the relationship between results-oriented culture and performance in public sector organizations in Vietnam. The research model and hypotheses have been tested by SmartPLS3 software with 289 survey samples from accountants and managers working in public sector organizations in Vietnam. The results show that results-oriented culture has a positive impact on organizational performance, and that financial accountability plays a mediating role in the relationship between results-oriented culture and organizational performance. These results provide some theoretical and administrative implications for public sector organizations in Vietnam in applying results-oriented culture to improve financial accountability and organizational performance.
Assessing Present and Future Climate Conditions for Beach Tourism in Jardines del Rey (Cuba)

This study assesses, adapting the weather types method, the suitability of the climate in Jardines del Rey (Cuba) for the practice of sun and beach tourism over the period 1991–2014, and the potential future impacts of climate change on this form of tourism on the basis of outputs from the PRECIS-Caribbean Regional Climate Model for the period 2021–2050. The methodology applied makes a classification of daily situations according to the most frequent combinations of climatological variables in tropical areas while focusing on a very specific segment of the tourism market (sun and beach tourism) and taking into account the behaviour of beach users and bioclimatic criteria. The results indicate that the distribution of weather types at the destination during the period 1991–2014 was highly consistent with the monthly distribution of tourists in Cuba, highlighting the existence of a low season from May to October and a high season between November and April. The future scenarios project an improvement in climate conditions for the practice of sun and beach tourism. This improvement is not based on a spectacular increase in favourable weather types compared to unfavourable ones, but rather on a better distribution of both.
LOSS AVERSION IS CONSISTENT WITH STOCK MARKET BEHAVIOR

The purpose of this paper is to verify that discrete statistical distributions of the US stock market are consistent with loss aversion. Loss aversion has the following tenets: an S-shaped valuation function, characterized by diminishing sensitivity, a loss aversion coefficient higher than +1, probability weighting, and reference-dependence. Diminishing sensitivity implies that the exponent of the valuation function is between 0 and +1. It is expected that this exponent be higher for losses. Probability weighting replaces objective with subjective probabilities. Loss aversion is indicated by a coefficient higher than +1 for the valuation of losses. There are three parameters: the two exponents of the valuation function, and the loss aversion coefficient. There is one non-linear equation: the certainty equivalence relation. The procedure is to fix two parameters and find the third parameter by solving the non-linear certainty equivalence equation, using the EXCEL spreadsheet. The program is repeated for more than one case about the fixed parameters, and by enriching the analysis with probability weighting. The calibrations executed point strongly to the conclusion that loss aversion is consistent with six discrete distributions of the first two moments of returns of the US stock markets. The calibration process provides for reasonable estimates of the key parameters of loss aversion. These estimates suggest a more pronounced diminishing sensitivity, and a higher than expected coefficient of loss aversion, especially when probability weighting is imposed.
Drivers of intention to use Murabaha financing: religiosity as moderator

Purpose The purpose of this paper is to investigate the determinants of Muslims’ attitude and intention towards Murabaha financing by considering religiosity as a moderator. Design/methodology/approach The data were collected through a survey of 373 Muslims in Afghanistan and were analysed using the partial least squares technique. Findings The results showed that social influence and religious obligation have a positive effect on attitude towards Murabaha financing. Furthermore, social influence and attitude have a positive effect on the intention to use Murabaha financing. Religiosity moderates negatively the impact of social influence on attitude towards Murabaha financing. Practical implications Managers and marketers of Islamic banks may benefit from the findings of this study, which provide insight into the factors that should be considered to promote Murabaha financing. Originality/value The findings contribute to the literature on Islamic financing products by demonstrating the drivers of attitude towards and intention to use Murabaha financing. The study also extends the literature by testing the moderating role of religiosity. Furthermore, the study extends the theory of reasoned action in the context of Islamic financing by introducing religious obligation as a potential driver of attitude and religiosity as a moderator.
Recovery of Municipal Solid Waste Recyclables under Different Incentive Schemes in Tamale, Ghana

The recovery of recyclables from the waste stream is a vital factor to consider in any recycling scheme since it enhances the quality of recyclables and ensures efficient recycling schemes. This study was conducted in the Tamale Metropolis of Ghana to investigate incentive options that can promote municipal solid waste resource recovery to support policy decisions on the formalization of recycling scheme in the Metropolis. Solid waste source separation scheme was set up in four different waste management service zones in the Metropolis. The quantity of separated materials, set-out rate, as well as separation efficiency of the targeted materials in the scheme were also assessed. The result of the study indicated a high recovery factor for dry recyclables (53.97%) as against food waste (10.03%). There was a significant effect of incentives on waste material quantities. Significant differences also occurred in the set-out rates and separation efficiency. Moreover, the study showed that employing prize as a reward scheme in addition to the provision of a waste storage facility had a high propensity for waste material recovery. The study demonstrated that the quantity of waste materials that may be retrieved in a recycling scheme in different solid waste management service zones depends on the type of incentive employed in the scheme and the service zone considered.
