Voltage Dependent Barrier Height, Ideality Factor and Surface States in Au/(NiS-PVP)/n-Si (MPS) type Schottky Barrier Diodes

: Metal-Polymer-Semiconductor (MPS) Schottky (SBD) were manufactured and their basic electrical parameters were obtained by the measurement of the forward and reverse bias current-voltage (I-V) in the wide bias voltage range (±3V) to determine the voltage dependent effects on Nickel-Sulphur (NiS) doped Poly Vinyl Pyrrolidone (PVP) polymer interlayer. The saturation current (I 0 ), zero-bias barrier height (Φ B0 ), rectifying rate (RR), ideality factor (n) and the real value of series - shunt resistances (Rs - Rsh) were calculated. The voltage dependent profile of n (V), Φ B (V), and Rs (V) were derived. The forward bias ln I-V plot of the MPS type SBD indicates a good rectifier behaviour and it has two distinctive linear parts with different slopes which correspond to low (0.288 ≤V ≤0.625 V) and moderate (0.672 ≤ V ≤ 0.960 V) bias voltages and then deviates from linearity due to Rs and interlayer at high forward bias voltages. Energy dependent profile of Nss was obtained from the forward bias I-V data by considering voltage dependent barrier height (Φ B ) and n. Nss plot represents U-shape behaviour in the forbidden bandgap. The mean value of Nss was found at about 7.0x10 12 eV -1 cm -2 and this value is in the acceptable limit for a semiconductor device and such lower values of Nss are the consequences of the passivation effect on the surface states.
A critical discussion of inclusive approaches to sexualities in ELT

The aim of this article is to challenge heteronormative as well as homonormative practices in English language teaching. In doing so, the paper demonstrates that both complete absence of LGBTQI+ references in ELT materials, as well as recent attempts to provide more inclusive approaches to materials design and classroom practices, can be problematic for L2 learners irrespective of their sexuality. The paper traces current developments in ELT materials design with regards to inclusive classroom practices and argues that attempts towards exclusivity may reflect (hetero/homo)normative views, and can therefore perpetuate a culture—learning and otherwise—of discrimination and social exclusion. It concludes by identifying the need for an alternative approach—one that does not focus on inclusion but on diversity.
Influence of orthodontic mini-screw surface modifications on implant topography and osseointegration: an in- vivo study.

ABSTRACT Introduction: Implant-supported orthodontic treatment has gained an expanded interest by researchers and orthodontists in the recent years. Therefore, different methods were tried to achieve the best results in this kind of treatment. Aim of the study: The current research was conducted to compare the effect of 2 different treatment methods on the surface of orthodontic titanium mini-screws and on bone response to the treated implants. Materials and methods: Forty-eight titanium mini-screw implants were distributed under 3 equal groups; as received, sandblasted, and laser-treated, respectively. After application of the surface-treatment methods, half of the selected screws were tested for surface morphology, using a scanning electron microscope (SEM) and a digital profilometer. To evaluate the biological effects of surface treatment methods, the other screws were implanted in rabbits’ tibias which were subjected to histological examination at the end of the experimental periods of 4 and 8 weeks. The surgical procedures and euthanasia were conducted according to the limitations of Research Committee of Mansoura University. Results: Sandblasted implants showed the highest surface roughness and the most pronounced bone response. Conclusion: Sandblasting surface treatment provide more favorable conditions for implant osseointegration, in comparison to laser-treatment.
Growth of Amorphous and Crystalline Silicon by HR-CVD (Hydrogen Radical Enhanced CVD)

Systematic studies have been made on preparation of Si thin films from SiF 4 under control over the flow of atomic hydrogens. The gas phase reactions taking place in the mixture of fragments (SiFn) resulting from plasma-induced dissociation and atomic hydrogens were widely investigated by a mass spectroscopy. Chemically active species,i.e., SiF 2 H and SiH 2 F were found as those related to the growth of films. The growth in the vicinity of substrates involves either endothermic or radical-enhanced reaction for the propagation of the three dimensional Si networks, accompaning release of terminators such as H and F. Accordingly, Si thin films with structures from amorphous to crystalline were obtained by controlling the flow of atomic hydrogen. A marked improvement in the hole-transport was established in the Si films containing hydrogen less than 5–6 at % due to the reduction in the tail states near the valence band.
Post-Disaster Spillovers: Evidence from Iranian Provinces

This paper studies the relationship between natural disasters and economic growth in the disaster-prone country of Iran, using a spatial Durbin panel model and covering the time period from 2010 to 2016 and including 29 provinces. The results of the empirical investigation suggest that there is a statistically significant positive relationship between the spatially-lagged occurrence of natural disasters and the change of the first difference of the natural logarithm of GDP per capita. Moreover, the estimations support the findings of previous cross-country studies, namely that we cannot find empirical evidence for a statistically significant direct effect of natural disasters on economic growth in the short term. When including time-lags, we can see a statistically significant positive effect of natural disasters on economic growth after two years. When taking into account the disaster type, which is mainly earthquake and flood in the case of Iran, the results suggest that the positive spillover effects are, rather, driven by earthquakes, and that there is a direct positive effect of floods in the short run. These findings extend existing literature and add new insights that are not just relevant for the case of Iran. The novelty of this study is that established and innovative approaches are used to study natural disasters on the provincial level, instead of the country level, and also take into account spatial spillover effects after disaster events that have been rarely discussed in literature.
Millennials Revisit Intention Based-Perceived Value in the Hospitality Industry: The Mediating Effect of Satisfaction

Recently, hotels have given significant attention to the millennials' generation, as they have become a niche market in the digital market era, and brought unique perspectives and values. Millennials have been raised as a new marketing goal for many hotel companies. Hotel Marketers consider Millennials' satisfaction and revisit intention as the most important strategies toward attracting them, to increase higher profit gain. Therefore, the purpose of this paper is two-fold. First, the study examines the hierarchical influence of the multiple dimensions of values perceived on the aspect of Millennials' satisfaction and revisits intention in the hospitality industry. Second, the study attempts to re-arrange the power of value perceived toward the digital generation from a hotel marketing perceptive. The study used a survey that has been conducted through a well self-administrated questionnaire. The population of the study included all the millennial hotel guests in Alexandria, the North coast, and Hurghada, Egypt. Data were analyzed using Linear Regression, mean and standard deviation. The study results reveal that the dimensions of perceived value are strong positive predictors for Millennials' satisfaction and revisit intention and significantly play an important positive impact on Millennials satisfaction. Finally, the study suggests that focusing on millennials’ value perception strategy can help to raise competitive advantage.
Shifting Gears: An Exploratory Study of Factors Impacting the Well-being of Retired Faith-based Ministers in Australia and New Zealand

ABSTRACT The rising tide of aged citizens globally suggests a compelling argument for increased understanding of factors impacting aging and retirement. Extended insight into the well-being of lesser studied groups offer suggestions to potentially enhance future planning for aging citizens. A study exploring the experience of clergy in Australia and New Zealand suggests a substantive theory on retirement in this context. A grounded study approach was adopted as best fit. Semi-structured interviews were conducted with 42 retired clergy and their wives. Findings suggest the underpinning role of spirituality in the primary elements of; choice, flexibility and connectivity as factors impacting the well-being of faith-based retirees in this context.

Association of 11beta-hydroxysteroid dehydrogenase type 1 (HSD11B1) gene polymorphism with Type 2 Diabetes Mellitus in a sample Egyptian Population

Background: Recently, numerous studies have associated polymorphisms in 11beta-hydroxysteroid dehydrogenase type 1 (HSD11β1) gene and T2DM risk. However, there is still a lack in the published literature evaluating the association between HSD11β1gene polymorphism and the risk of T2DM. Objective: The Aim of the study was to assess the association of HSD11β1gene polymorphism (rs846910) with Type 2 diabetes mellitus (T2DM) in a sample of the Egyptian population. Patients and methods: Our study was conducted on 100 subjects; their mean age was 50.26 ± 9.1 years old. They were selected from Diabetes Outpatient Clinics of our institution for 6 months in the period from June 2019 to December 2019. They were divided into two groups: 60 type 2 diabetic obese patients with BMI > 25 kg/m (Group I) and 40 ageand sex-matched controls (Group II). Results: There was no statistically significant difference between cases and controls in terms of HSD11β1 polymorphism (rs846910). The regression analysis showed that the HSD11β1 polymorphism did not significantly increase the risk of diabetes mellitus (DM). Detection of HSD11β1 gene polymorphism in the study showed that homozygous GG genotype was more prevalent than GA genotype. However, there was no significant difference between GG and GA in terms of fasting and postprandial sugar and in terms of lipid profile. Conclusion: The present study showed no significant association between HSD11β1 polymorphism (rs846910) and T2DM. Moreover, the HSD11β1polymorphism (rs846910) is not correlated with glycemic status or lipid profile.
Short- and Long-Term Effects of Lime and Gypsum Applications on Acid Soils in a Water-Limited Environment: 3. Soil Solution Chemistry

Aluminum (Al) toxicity imposes a significant limitation to crop production in South Western Australia. This paper examines the impact of surface-applied lime and gypsum on soil solution chemistry in the short term (1 year) and the long-term (10 years) in water limited environments. In the experiments, we measured soil solution chemistry using a paste extract on soil profile samples collected to a depth of 50 cm. We then used the chemical equilibrium model MINTEQ to predict the presence and relative concentrations of Al species that are toxic to root growth (Al associated with Al3+ and AlOH2 or Toxic-Al) and less non-toxic forms of Al bound with sulfate, other hydroxide species and organic matter. A feature of the soils used in the experiment is that they have a low capacity to adsorb sulfate. In the short term, despite the low amount of rainfall (279 mm), sulfate derived from the surface gypsum application is rapidly leached into the soil profile. There was no self-liming effect, as evidenced by there being no change in soil solution pH. The application of gypsum, in the short term, increased soil solution ionic strength by 524–681% in the 0–10 cm soil layer declining to 75–109% in the 30–40 cm soil layer due to an increase in soil solution sulfate and calcium concentrations. Calcium from the gypsum application displaces Al from the exchange sites to increase soil solution Al activity in the gypsum treatments by 155–233% in the short term and by 70–196% in the long term to a depth of 40 cm. However, there was no effect on Toxic-Al due to Al sulfate precipitation. In the long term, sulfate leaching from the soil profile results in a decline in soil solution ionic strength. Application of lime results in leaching of alkalinity into the soil profile leading to a decreased Toxic-Al to a depth of 30 cm in the long term, but it did not affect Toxic-Al in the short term. Combining an application of lime with gypsum had the same impact on soil solution properties as gypsum alone in the short term and as lime alone in the long term.
Quantitative Determination by X-Ray Diffractometry of Calcium Sulfate and Calcium Carbonate in Airborne Dusts

Abstract A quantitative simultaneous determination method by X-ray powder diffractometry is described for calcium sulfate and calcium carbonate in airborne dusts. In order to eliminate the mutual interference among diffraction peaks, and to avoid the presence of the hydration isomers of calcium sulfate, dust samples were heated at 350°C for 2 h. To reduce the errors due to the difference-in crystallinity between the standard materials and the samples, the synthesized calcium sulfate anhydrate (anhydrite) was heated to such an extent that the half-width of the 002,020 peak was identical with that of the anhydrite in pretreated dust samples. Standard calcium carbonate (calcite) was ground until the half-width and the orientation index of the 104 peak of calcite was identical with that of the calcite in dust samples. Linear calibration curves were obtained throughout the range of 0 ∼ 30 wt% for anhydrite and the range of 0 ∼ 10 wt% for calcite, respectively. The determination limits were 0.2 wt% for anhydrite and 0.3 wt% for calcite. Relative standard deviations were 3.4 % for 8.0 wt% of anhydrite and 1.8% for 5.4 wt% of calcite. The present method is applicable to determination of calcium sulfate and calcium carbonate in actual dust samples.
A Maximum Rank Theorem for Solutions to the Homogenous Complex Monge-Amp\`ere Equation in a $\mathbb{C}$-Convex Ring

Suppose $\Omega_0,\Omega_1$ are two bounded strongly $\mathbb{C}$-convex domains in $\mathbb{C}^n$, with $n\geq 2$ and $\Omega_1\supset\overline{\Omega_0}$. Let $\mathcal{R}=\Omega_1\backslash\overline{\Omega_0}$. We call $\mathcal{R}$ a $\mathbb{C}$-convex ring. We will show that for a solution $\Phi$ to the homogenous complex Monge-Amp\`ere equation in $\mathcal{R}$, with $\Phi=1$ on $\partial\Omega_1$ and $\Phi=0$ on $\partial\Omega_0$, $\sqrt{-1}\partial\overline{\partial}\Phi$ has rank $n-1$ and the level sets of $\Phi$ are strongly $\mathbb{C}$-convex.
Assessment of the Ameliorative Effect of Bacillus subtilis against the Toxicity Induced by Aflatoxin B1 in Rats

Aflatoxin B1 (AFB1) is the most toxic and common among the major types of aflatoxins. AFB1 is hepatoxic and has been implicated in an increase risk of hepatocellular carcinoma, also the effect of AFs on the brain chemistry have been documented. Probiotics have health benefits and provide of powerful benefits for the body and brain. The present study was designed to reveal efficiency of Bacillus subtilis NS4182-01 against the hematological, biochemical and histopathological alterations induced by AFB1 in rats. Both of AFB1 and B. subtilis were studied on the experimental animals (rats) that were divided into 6 groups as the following: Group 1 (control) received distilled water orally. Groups 2&3 (B. subtilis treated groups) received B. subtilis orally at a dose of 0.25 and 0.50 ml, respectively. Group 4 (AFB1 treated group) orally treated with AFB1 at a dose of 2 mg/kg b.w. Groups 5&6 (AFB1 + B. subtilis group) orally treated with AFB1 and then treated with B. subtilis at two studied doses respectively. It was noticed that the hematological measurements declined and the most biochemical measurements elevated significantly (P≤0.05) in AFB1 treated group. B. subtilis restored all studied measurements towards the normal values. Moreover, the native electrophoretic protein patterns showed that the physiological alterations occurred in the native protein and lipid moiety in addition to calcium moiety of native protein patterns as a result of AFB1 treatment were represented by hiding one or more of normal protein types with existence of abnormal ones. Therefore, the similarity index (SI%) and genetic distance (GD%) values were altered with protein (SI=40.00%; GD=60.00%), lipid moiety (SI=50.00%; GD=50.00%) and calcium moiety of native protein patterns (SI=75.00%; GD=25.00%) in AFB1 treated group. Although the treatment with B. subtilis at a dose of 0.25 ml showed ameliorative effect but could not restore the physiological state of the patterns to normalcy. While B. subtilis at a dose of 0.50 ml restored integrity of these native protein patterns by restoring the absent types with hiding the abnormal ones. Therefore, this group became physiologically similar to control group (SI=100.00%; GD=0.00%). These findings were supported by results of the histopathological examination in the most target organs (liver, kidney and brain) that were affected by AFB1 and the B. subtilis restored their histopathological integrity to normal structure and maintained architecture of these organs.
Sol-Gel Processing of a Covalent Organic Framework for the Generation of Hierarchically Porous Monolithic Adsorbents

Covalent organic frameworks (COFs) have emerged as a versatile materials platform for applications including chemical separations, water purification, chemical reaction engineering and energy storage. Their inherently low mechanical stability, however, frequently renders existing methods of pelletisation ineffective contributing to pore collapse, pore blockage or insufficient densification of crystallites. Here, we present a general process for the shaping and densifying of COFs into centimetre-scale porous monolithic pellets without the need for templates, additives or binders. This process minimises mechanical damage from shear-induced plastic deformation and further provides a network of interparticle mesopores that we exploit in accessing analyte capacities above those achievable from the intrinsic porosity of the COF framework. Using a lattice-gas model, we accurately capture the monolithic structure across the mesoporous range and tie pore architecture to performance characteristics in both gas storage and separation applications. Collectively, these findings represent a substantial step in the practical applicability of COFs and other mechanically weak porous materials.
Symbolic interaction of internal auditor in the implementation of consultation activities

Disaster is one of impacts caused by climate change. The Audit Board of the Republic of Indonesia conducts an audit of state finances management and responsibility in handling the disaster. The success of The Audit Board of the Republic of Indonesia was partly driven by The Audit Board of the Republic of Indonesia’s internal audit performance, namely the Inspectorate General which provided consultations to add value for the The Audit Board of the Republic of Indonesia work unit. However, The Audit Board of the Republic of Indonesia work unit expects that Inspectorate General has more consultative and not impressed as an external auditor in carrying out the consultation. The purpose of this research was to improve and enrich the communication of Inspectorate General internal auditors in carrying out the consultation. This research used symbolic interaction theory by George Herbert Mead. This paper is a compilation of several relevant data sources. They were collected systematically, and then analyzed in-depth and critical evaluation to provide the research finding in narrative. The result showed that management of mind, self, and society can play important role in carrying out the consultation. Besides, the use of symbol and nonverbal communication may increase good relationship in the consultation. Inspectorate General needed to improve its auditors competence to manage symbolic interaction in carrying out the consultation in order to be more consultative.
Fossil bivalves and the sclerochronological reawakening

Abstract. The field of sclerochronology has long been known to paleobiologists. Yet, despite the central role of growth rate, age, and body size in questions related to macroevolution and evolutionary ecology, these types of studies and the data they produce have received only episodic attention from paleobiologists since the field's inception in the 1960s. It is time to reconsider their potential. Not only can sclerochronological data help to address long-standing questions in paleobiology, but they can also bring to light new questions that would otherwise have been impossible to address. For example, growth rate and life-span data, the very data afforded by chronological growth increments, are essential to answer questions related not only to heterochrony and hence evolutionary mechanisms, but also to body size and organism energetics across the Phanerozoic. While numerous fossil organisms have accretionary skeletons, bivalves offer perhaps one of the most tangible and intriguing pathways forward, because they exhibit clear, typically annual, growth increments and they include some of the longest-lived, non-colonial animals on the planet. In addition to their longevity, modern bivalves also show a latitudinal gradient of increasing life span and decreasing growth rate with latitude that might be related to the latitudinal diversity gradient. Is this a recently developed phenomenon or has it characterized much of the group's history? When and how did extreme longevity evolve in the Bivalvia? What insights can the growth increments of fossil bivalves provide about hypotheses for energetics through time? In spite of the relative ease with which the tools of sclerochronology can be applied to these questions, paleobiologists have been slow to adopt sclerochronological approaches. Here, we lay out an argument and the methods for a path forward in paleobiology that uses sclerochronology to answer some of our most pressing questions.
Sub-TgCross-Linking of a Polyimide Membrane for Enhanced CO2Plasticization Resistance for Natural Gas Separation

Decarboxylation-induced thermal cross-linking occurs at elevated temperatures (∼15 °C above glass transition temperature) for 6FDA–DAM:DABA polyimides, which can stabilize membranes against swelling and plasticization in aggressive feed streams. Despite this advantage, such a high temperature might result in collapse of substructure and transition layers in the asymmetric structure of a hollow fibers based on such a material. In this work, the thermal cross-linking of the 6FDA–DAM:DABA at temperatures much below the glass transition temperature (∼387 °C by DSC) was demonstrated. This sub-Tg cross-linking capability enables extension to asymmetric structures useful for large scale membranes. The resulting polymer membranes were characterized by swelling in known solvents for the un-cross-linked materials, TGA analysis, and permeation tests of aggressive gas feed stream at higher pressure. The annealing temperature and time clearly influence the degree of cross-linking of the membranes, and results in a sli.
