Polymeric Films Containing Tenoxicam as Prospective Transdermal Drug Delivery Systems: Design and Characterization

The administration of drugs via transdermal therapeutic systems has become an attractive form of therapeutic approach, considering its advantages and the high patient compliance achieved, making them a viable alternative, especially in the treatment of chronic diseases. The purpose of our study was the development of polymer-based films containing tenoxicam (TX) and the analysis of dissolution kinetics. Auxiliary substances represent an important part of pharmaceutical forms, so during the first stage, TX and excipient compatibility were verified. Fourier Transform Infrared Spectroscopy (FT-IR) and Differential Scanning Calorimetry (DSC) analyses were performed on TX and on physical mixtures of TX-HPMCE5 and TX-HPMC15kcP. Three polymeric films of TX (TX1, TX2, and TX3) were prepared using a solvent evaporation technique. Release studies were done at 32 °C ± 1 °C with a Franz diffusion cell. The results of the DSC and FT-IR analyses demonstrated the compatibility of the active substance with the two matrix-forming polymers. The results obtained in the release studies of TX from the proposed polymeric films suggested a pH-dependent behavior in all three polymeric films. At pH 5.5, flux values were between 8.058 ± 0.125 μg·cm−2·h−1 and 10.850 ± 0.380 μg·cm−2·h−1; and at pH 7.4, between 10.990 ± 0.2. 490 μg·cm−2·h−1 and 53.140 ± 0.196 μg·cm−2·h−1. The Korsmeyer–Peppas model described a non-Fickian transport mechanism. The n values varied between 0.63–0.7 at pH 5.5 and 0.73–0.86 at pH 7.4, which suggested a diffusion depending on the matrix hydration and polymer relaxation.
Collocational Development during a Stay Abroad

The purpose of the current study was to explore if and how additional-language learners may show changes in phraseological patterns over the course of a stay in a target-language environment. In particular, we focused on noun+adjective combinations produced by a group of additional-language speakers of French at three points in time, spanning 21 months and including an academic year in France. We extracted each combination from a longitudinal corpus and determined frequency counts and two strength-of-association measures (Mutual information [MI] score and Log Dice) for each combination. Separate analyses were conducted for frequency and the strength-of-association measures, revealing that phraseological patterns are significantly predicted by adjective position in the case of all three measures, and that MI scores showed significant change over time. We interpret the results in light of past research that has reported contradictory findings concerning change in phraseological patterns following an immersion experience.
Kinetics of iron absorption in normal dogs

By means of the simultaneous use of two radioactive isotopes of iron, it has been possible to measure the rate of iron absorption from the gastrointestinal tract in normal dogs. One isotope was administered orally and another intravenously. By suitable calculation the rates of absorption at any given time were computed. Absorption begins at a very high rate, which varied from 22.8 µg/hr to 578 µg/hr in different dogs. The half-time of the absorption rate varied from 0.25 to 0.66 hr. The rapid fall in the rate of iron absorption is not caused entirely by the passage of the labeled material along the intestinal tract, but seems rather to be caused by the development of an inhibitory mechanism or the presence of a rate-limiting reaction in one of the steps in the passage of iron from the intestinal lumen to the plasma.

A verification of motivations for over-the-top binge and short viewing of audio-visual content

ABSTRACT The current study purposes to verify the motivations for the consumption of audio-visual content through binge-viewing or short watching. It is grounded in the uses and gratification perspective to examine five distinct types of stimuli for binge-viewing and short watching: enjoyment, efficiency, information seeking, social interaction, and relaxation. Results of the analyses demonstrate that enjoyment and efficiency are positively associated with the tendency toward binge-viewing. However, the inclination toward short watching is correlated to enjoyment, efficiency, social interaction, and information seeking, and relaxation was not predictive of either inclination. The study also contemplated loneliness and addiction as moderating variables for binge-viewing and short watching behaviour. Structural equation modelling (SEM) was employed to validate the moderating effects of these two psychological states. The SEM results of the two-group analysis revealed that loneliness and addiction affected motivation and influenced attitudes toward binge-viewing and short watching. The present study is one of the first attempts to verify and compare the media viewing behaviours of binge-watching and short watching. Thus, it can contribute substantially to a more comprehensive scholarly understanding of over-the-top consumption of audio-visual content.
Pinecone-like hierarchical anatase TiO2 bonded with carbon enabling ultrahigh cycling rates for sodium storage

Hierarchical anatase TiO2 homogeneously tuned by using carbon through Ti–C bonds has been designed, exploiting carbon quantum dots as uniform carbon additives and functionalization inducers for structure tailoring and surface modification. The fabricated pinecone-like structure constructed by ultrafine subunits presents a highly increased surface area (202.4 m2 g−1) and abundant mesopores. Surface bonded carbon significantly boosts its electronic conductivity derived from both the conductive carbon and accompanied oxygen vacancies. When utilized in sodium-ion batteries, it delivers a high reversible specific capacity of 264.1 mA h g−1 at a rate of 0.1C (33.6 mA g−1) and still maintains 108.2 mA h g−1 even after 2000 cycles at 10C with a retention of 94.7% outstandingly. Notably, its Na+ intercalation pseudocapacitive behavior is enhanced by the modulated TiO2/carbon interfaces, facilitating a fast (de-)sodiation process. Combining the elaborate hierarchical structure with the unique surface composition, synergetic merits are noticed when the promoted kinetics, improved electronic conductivity, increased electrolyte penetration areas and shortened Na+ diffusion length are achieved simultaneously, giving rise to remarkable high-rate capabilities and long-term cyclability.
Paradigmatic restructuring and the diachrony of stem alternations in Chichimec

Abstract:Stem alternations contribute a unique type of morphological complexity to inflectional systems (Baerman et al. 2015), but despite the fact that they can show remarkable stability over time (Maiden 2018), the manner in which they are maintained and the types of changes they undergo are still poorly understood, in particular when it comes to understudied languages for which diachronic data are usually nonexistent. The verbal inflection of Chichimec (Oto-Pamean, Mexico) is characterized by intricate distributions of stem alternations, and it affords us a unique opportunity to study them from a diachronic perspective, because, unlike most other minority languages, we have a precise and detailed description of its verbal inflection system from almost a century ago (de Angulo 1933) from which we are able to reconstruct the paradigms of 170 verbs. In this article, we compare the verbal system as it was registered by de Angulo in 1930 to our own primary data recorded during two recent field trips. We show evidence that certain elements of the intricate patterns of stem alternations have been reanalyzed and redistributed by the speakers. We argue that the changes make sense only from a morphological perspective in which stem alternations are seen as involving fixed configurations of cells, or 'morphomes' (Aronoff 1994). We also show that speakers have not manipulated these configurations in isolation but in clusters, resulting in a substantial restructuring of verbal inflection at the paradigmatic level. We conclude that the changes have not resulted in a simpler system, but rather one that, while almost the same in terms of morphological complexity, has become more consistent.
Experimental Study of Single Taylor Bubble Rising in Stagnant and Downward Flowing Non-Newtonian Fluids in Inclined Pipes

An experimental investigation of single Taylor bubbles rising in stagnant and downward flowing non-Newtonian fluids was carried out in an 80 ft long inclined pipe (4°, 15°, 30°, 45° from vertical) of 6 in. inner diameter. Water and four concentrations of bentonite–water mixtures were applied as the liquid phase, with Reynolds numbers in the range 118 < Re < 105,227 in countercurrent flow conditions. The velocity and length of Taylor bubbles were determined by differential pressure measurements. The experimental results indicate that for all fluids tested, the bubble velocity increases as the inclination angle increases, and decreases as liquid viscosity increases. The length of Taylor bubbles decreases as the downward flow liquid velocity and viscosity increase. The bubble velocity was found to be independent of the bubble length. A new drift velocity correlation that incorporates inclination angle and apparent viscosity was developed, which is applicable for non-Newtonian fluids with the Eötvös numbers (E0) ranging from 3212 to 3405 and apparent viscosity (μapp) ranging from 0.001 Pa∙s to 129 Pa∙s. The proposed correlation exhibits good performance for predicting drift velocity from both the present study (mean absolute relative difference is 0.0702) and a database of previous investigator’s results (mean absolute relative difference is 0.09614).
Development of a Framework to Compare Low-Altitude Unmanned Air Traffic Management Systems

Several reports forecast a very high demand for Urban Air Mobility services such as package delivery and air taxi. This would lead to very dense low-altitude operations which cannot be safely accommodated by the current air traﬃc management system. Many diﬀerent architectures for low-altitude air traﬃc management have been proposed in the literature, however, the lack of a common framework makes it diﬃcult to compare strategies. The work presented here establishes eﬃciency, safety and capacity metrics, deﬁnes the components of an automated traﬃc management system architecture and introduces a preliminary framework to compare diﬀerent alternatives. This common framework allows for the evaluation and comparison of diﬀerent alternatives for unmanned traﬃc management. The framework is showcased on different strategies with diﬀerent architectures. The impact of algorithmic choices and airspace architectures is evaluated. A decoupled approach to 4D trajectory planning is shown to scale poorly with agents density. The impact of segregating traﬃc by heading is shown to be very diﬀerent depending on the algorithms and airspace access rules chosen.
PBL with the Application of Multiple and Nonlinear Linear Regression in Chemical Kinetics and Catalysis

In the resolution of problems in chemical kinetics and catalysis the mathematical models relate the independent variable that is usually time, with the dependent variable which is normally the concentration of a reactant. They conform to linear models, whose parameters such as the ordering to origin and the slope are kinetic parameters, applying linear regression to the experimental data can be obtained linear models that are the simplest to be found. On other side, multiple models can be found with two or more independent variables, however, there are models that are not feasible to linearize and therefore you can make use of nonlinear regression. This paper is exemplified by the Problem-Based Learning (PBL) scheme and the use of software such as Stat graphics and Polymath to solve the resulting mathematical models. The results obtained are compared with traditional methods as multiple linearized least squares, in this way the learning teaching process is strengthened, since the student raises the kinetic model and then solves it with computer tools. Through the PBL cycles generated in the resolution of real problems in chemical kinetics and catalysis, significant learnings are achieved on difficult comprehension topics such as initial rate for the determination of the reaction order, half-life times, temperature effect and heterogeneous catalysis.
A Three-Terminal Carbon Nanorelay

Three-terminal nanorelay structures were fabricated with multiwall carbon nanotubes (MWNTs). The nanotube relays were deflected by applying a gate voltage until contact (mechanical and/or electrical) was made with a drain electrode, thus closing the circuit. It was possible to achieve multiple switching cycles, showing that carbon nanotubes are suitable and practical systems for developing nanoelectromechanical devices of this kind.
Service Climate and Empowerment for Customer Service Quality among Vietnamese Employees at Restaurants

This study examines the relationship between service climate, empowerment, and organizational citizenship behavior among Vietnamese employees at restaurants in urban areas of South Korea. Moreover, the mediating role of empowerment between service climate and organizational citizenship behavior is investigated. From a sample of 209 Vietnamese respondents working in Asian ethnic restaurants, the findings indicate that work facilitation is the most influential service climate that affects empowerment. However, two service climate factors—managerial support and customer orientation—are not statistically significant. Moreover, organizational citizenship behavior among employees is enhanced not only by service climate but also by empowerment. This study provides empirical evidence of employee perceptions of service climate and of the influence of service climate on employee empowerment and organizational citizenship behavior for customer service quality. This study expands the knowledge regarding foreign employees at restaurants and provides important theoretical and practical implications for creating a sustainable work environment and empowering employees who strive for an excellent quality of customer service in the context of the restaurant industry.
Non-Linear Motion Characteristics of a Shallow Draft Cylindrical Barge Type Floater for a FOWT in Waves

A shallow draft cylindrical barge type floater with footing close to the water surface was experimentally evaluated in waves to investigate non-linear motion characteristics. The floater was designed to be used as an option for FOWT—floating offshore wind turbines. The non-linear mechanism can be promoted due to the viscous force that acts on the footing edges and the footing interaction with the free surface. In general, the observed non-linear viscous damping is modeled as a force proportional to the square of the relative velocity between the floater and the water. Therefore, the viscous damping levels is expected to increase, and the response in waves, to decrease. However, an increase in motion responses was observed for a broad range of wave periods. An attempt was made to clarify the hydrodynamic mechanism by comparing wave tank experiments, numerical calculations by CFD—computational fluid dynamics codes, and linear potential theory codes. Regular wave tests for three different wave height conditions were carried out, including free decay tests in still waters. For CFD simulations, the OpenFOAM code was selected. For potential theory simulations, the WAMIT code was chosen. As a result of the research, three points could be highlighted and discussed: first, the hydrodynamic phenomenon that contributed to the non-linear motion of the floater was identified; second, the increase and coupling of the motions response of heave and pitch motions; and finally, the phenomenon that the footing held water mass and lifted it to the water surface. The CFD calculations were able to get good qualitative results compared with the experiments and confirmed the use of CFD as a useful tool to capture the non-linear hydrodynamic phenomenon. The linear potential theory was not able to capture the phenomenon discussed herein.
Climate change can trigger fall armyworm outbreaks: a developmental response experiment with two Mexican maize landraces

Abstract Maize is one of the most important crops in the world, particularly in Mexico where it was domesticated and is central to traditional cultures. The fall armyworm (Spodoptera frugiperda [J.E. Smith]), is a major pest that can greatly reduce production of this crop. Climate change also threatens maize production, as projections estimate an increase of fall armyworm outbreaks. For these reasons, (1) we assessed the changes in the S. frugiperda life cycle along a temperature gradient ranging from 23 °C to 31 °C, and (2) assessed the development of larvae feeding on two Mexican landraces and the responses of each landrace to herbivory under current and predicted climatic conditions; both assessments were conducted under laboratory conditions. Development was faster and each life cycle stage was shorter at higher temperatures. The effect of herbivory differed between the landraces; herbivory was more harmful for White Ranchero than for Yellow. As warmer and drier conditions are expected during this century, sowing appropriate maize landraces that can cope with herbivores under climate change could mitigate potential economic losses.
Tax Revenue, Capital Formation, and Economic Growth in Nigeria

Economic growth drivers aimed at stimulating and stabilizing the economies of the countries to engender sustainable growth. Studies have shown that Nigeria has been plagued with stunted and faltering economic growth over the years. Tax and other relevant macroeconomic policies are implemented by the government to smoothen out economic fluctuations but this has not been fully harnessed. A causal-effect study was conducted between tax revenue, gross fixed capital formation and economic growth using a 38-year time series data from 1981 to 2018 derived from CBN statistical bulletin. It was found that tax revenue (TR) had significant positive effect on Gross Domestic Product and Gross Fixed Capital Formation (GFCF) significantly controls the relationship between TR and GDP. It is evidenced that the country relied heavily on taxes as major source of revenue. The study recommended that government should widen its tax net, creates expansionary measures to enhance its tax revenue in order to boost its GDP. The government should also create an enabling environment for economy diversifications in order to increase revenue generated via other means than taxes in order to spur economic growth and avoid over-reliance on taxes.
Sustainable Food Consumption: Investigating Organic Meat Purchase Intention by Vietnamese Consumers

Promoting sustainable food consumption contributes to the achievement of the United Nation’s Sustainable Development Goals. This study investigated the key determinants of consumer intention to purchase organic meat in an emerging market and a unique model was developed by incorporating environmental concern and guilt with the key components of the Theory of Planned Behavior. This model was then validated by obtaining data from a sample of 402 Vietnamese consumers at five food stores in Ho Chi Minh City, using a paper-based survey. The findings reveal that consumers who are concerned about the environment are likely to formulate favorable attitudes and downplay monetary barriers associated with organic food purchase. In addition, while attitudes and guilt about buying conventional meat have a positive effect on organic meat purchase intention, perceived monetary barriers significantly reduce the intention. These findings highlight both the rational and emotional aspects of organic food purchase intention and have important implications for key stakeholders and the encouragement of organic meat consumption.
The Effectiveness of Teacher Electronic Feedback in Asynchronous Teaching: A Case Study of Foundation Students at Sultan Qaboos University

Due to the Covid-19 pandemic, educational systems worldwide, including Oman, were affected as this led to temporary closures of schools, colleges, and universities. In response to such closures, many countries decided to continue offering education through distance learning. Similarly, Sultan Qaboos University (SQU), the only government university in Oman, opted for asynchronous teaching through Emergency Remote Teaching (ERT). Through ERT, there is a temporary shift in instructional delivery. Its primary aim is to provide temporary access to instruction and support materials quickly and reliably during the crisis. Asynchronous teaching provides students with flexibility to access the materials posted by teachers whenever they can, leaving teachers with many challenges. One of these challenges is the ability to offer proper feedback to students. Therefore, this study aimed to examine the perceptions of both teachers and students on the electronic feedback provided in ERT. A total of 8 teachers 80 students enrolled in the foundation program at SQU participated in the study. The responses of both teachers and students were collected through online questionnaires and semi-structured interviews. The findings of the study indicate that some feedback methods seemed to be more effective. The study also identified the challenges faced by both students and teachers in terms of electronic feedback. Furthermore, the study gives suggestions to improve electronic feedback methods.
