Published: August 2022

Herbs are staging a comeback and herbal ‘renaissance’ is happening all over the globe. The herbal products, today, symbolize safety, in contrast to the synthetics that are regarded as unsafe to humans and the environment. An herb, botanically speaking, is any plant that lacks the woody tissue which is characteristic of shrubs or trees. More specifically, herbs are plants which are used medicinally or for their flavor or scent. Herbs with medicinal properties are a useful and an effective source of treatment for various disease processes. Herbal extracts have been successfully used in dentistry as tooth cleaning and antimicrobial plaque agents. The use of herbal medicines continues to expand rapidly across the world. Many people take herbal medicines or herbal products now for their health care in different national healthcare settings. Herbal extracts have been used in dentistry for reducing inflammation, as antimicrobial plaque agents, for preventing release of histamine and as antiseptics, antioxidants, antimicrobials, antifungals, antibacterials, antivirals and analgesics. They also aid in healing and are effective in controlling microbial plaque in gingivitis and periodontitis, thereby improving immunity.
ARTIFICIAL SWEETENERS-A REVIEW
Authors: Channesh Patel  , Sathya Kumaresan
Published: August 2022

Nonnutritive sweeteners (NNS) have become an important part of everyday life and are increasingly used nowadays in a variety of dietary and medicinal products. They provide fewer calories and far more intense sweetness than sugar-containing products. Six of these agents (aspartame, saccharine, sucralose, neotame, acesulfame-K, and stevia) have previously received a generally recognized as safe status from the United States Food and Drug Administration, and two more (Swingle fruit extract and advantame) have been added in the recent years to this ever-growing list. They are claimed to promote weight loss and deemed safe for consumption by diabetics; however, there is inconclusive evidence to support most of their uses and some recent studies even hint that these earlier established benefits regarding NNS use might not be true. There is a lack of properly designed randomized controlled studies to assess their efficacy in different populations, whereas observational studies often remain confounded due to reverse causality and often yield opposite findings. Pregnant and lactating women, children, diabetics, migraine, and epilepsy patients represent the susceptible population to the adverse effects of NNS-containing products and should use these products with utmost caution. The overall use of NNS remains controversial, and consumers should be amply informed about the potential risks of using them, based on current evidence-based dietary guidelines.
DESMOSOMES IN ORAL DISEASES – A REVIEW
Authors: Bisena Jayashree
Published: August 2022

Desmosomes are the adhesion proteins that function both as an adhesive complex and as a cell surface attachment site for keratin intermediate filaments of the cytoskeleton. Desmosomes are more widely distributed along the lateral membranes. Desmosomes contain two types of transmembrane proteins desmogleins and desmocollins which belong to cadherin family. These desmosomal cadherins are linked to the keratin cytoskeleton via several cytoplasmic proteins such as desmoplakin and plakoglobin. Desmosomes play a critical role in the maintenance of normal tissue architecture. They are frequently mutated and desmosomal adhesion is compromised by antibodies in autoimmune diseases and result in blistering disorders in epithelium. Inherited mutations in genes in desmosomal constituents can also affect the skin and the heart. Desmosomes may have a tumour suppressor function and desmosomal cadherins have the capacity to suppress the invasiveness of cells in culture.

Published: August 2022

We report a case of unicystic ameloblastoma with mucous cell differentiation in the anterior maxilla who suffered from painful swelling for 2 months. A radiograph showed a irregular radiolucent lesion between the roots of 21, 22 and 23.

Microscopic examination revealed the cystic lesion was lined with ameloblastic epithelium and goblet cells in the epithelium. The mucous cells reacted positively to PAS stain. The possible pathogenic mechanism of this case reflects the pluripotential character of the odontogenic epithelium. The prognosis is probably that expected for conventional unicystic ameloblastoma. Significance of identifying such case of mucous metaplasia in unicystic ameloblastoma is that it should be differentiated from mucous cell containing lesions like glandular odontogenic cyst and mucoepidermoid carcinoma.

The investigation utilized yearly data for the year 1973-2020. By applying the autoregressive distributed lag (ARDL) technique, the study examines both short-term and long-run effects of domestic private investment (DPI) on output growth in large-scale manufacturing.However,  the study affirms a positive and significant relationship among domestic private investment, exports and value-added, large-scale manufacturing (VAL) in both short-and long-run, while market size and inflation also have a negatively and significantly influence on the value-added, large-scale manufacturing sector. It is also confirmed that domestic private investment, export, inflation have a bidirectional causal relationships with large-scale manufacturing, value-added. Moreover, findings also implies that unidirectional causality is running between employment (EMP),  market size (MS), and large-scale manufacturing growth output growth (VAL). Hence, numerous incentives with tax cuts or subsidizations must be sponsored by the supervision of government in a direction to foster private investment. Provided that political stability, better infrastructure, and management in industrial manufacturing zones empowers to attract transnational exports by improving law and order conditions in Pakistan.

Published: August 2022

Enzymatic degradation has been revealed as an effective method of eradicating polyethylene pollution and different studies have opined lignolytic enzymes to be involved in the process of low-density polyethylene biodegradation. This study focused on screening and characterization of manganese peroxidase and laccase produced by Staphylococcus saprophyticus exposed to low- density polyethylene. The result showed that Staphylococcus saprophyticus produced optimum manganese peroxidase and laccase activities on the third and second days. A study of the physicochemical properties of manganese peroxidase and laccase revealed that their activities were optimum and stable at acidic pH (pH 3 and pH 3 respectively). Manganese peroxidase had optimum temperature activity at 50 oC and was stable at 60°C while laccase was active at 70°C and most stable at 80°C. Staphylococcus saprophyticus produced thermostable acidophile lignolytic enzymes, therefore it can be used for polyethylene biodegradation.

Les cadres normatifs et procéduraux nationaux dans la lutte contre l’impunité des crimes internationaux et violations des droits de l’homme dans la région des grands lacs : une harmonisation nécessaire?
Authors: Raphael Tshisumpa Muelu , Elie Ahadi Byumanine
Published: August 2022

Le constat d’interdépendance des Etats et l’ampleur des défis pénaux, qui ne peuvent être conjurés que collectivement, engendrent un vaste réseau d’organisations multilatérales et bilatérales, d’unions économiques ou d’alliances militaires en vue de répondre à des besoins réels de coopération, voire d’harmonisation. La République démocratique du Congo, le Rwanda et le Burundi ont, dans cette occurrence, mis sur pied la Communauté économique dans la région des Grands-Lacs. Bien que les objectifs de cette Communauté soit claire dans la coopération judiciaire en matière pénale, les cadres normatifs et procéduraux nationaux respectifs méritent une harmonisation certaine pour une coopération efficace et réciproquement avantageuse.
Der Einfluss von Täter- und Opferidentitäten auf emotionale Reaktionen auf terroristische Gewalt in Deutschland
Authors: Berger Lars , Lau Stephan
Published: August 2022

Als politische Strategie ist terroristische Gewalt abhängig von den emotionalen Reaktionen, die sie beim Zielpublikum auslöst. Die Verbreitung von Angst und Wut soll helfen, gesellschaftliche und politische Veränderungen im Sinne des terroristischen Kalküls herbeizuführen. Daher sind diese Emotionen gleichermaßen bedeutsam für Terrororganisationen wie auch für staatliche Terrorismusbekämpfungsmaßnahmen. Angesichts der sich in Deutschland und vielen westlichen Staaten verändernden Bedrohungslage erweitert unsere Studie den für die bisherige Forschung typischen Fokus auf den islamistischen Terrorismus durch die vergleichende Beschäftigung mit emotionalen Reaktionen auf rechtsterroristische Gewalt. Mit Hilfe eines Experiments überprüfen wir, welche Wirkungen unterschiedliche Geschlechter- und Gruppenidentitäten auf Seiten der Täter und Täterinnen sowie auf Seiten der Opfer für emotionale Reaktionen auf terroristische Gewalt in Deutschland haben. Unsere Studie zeigt, dass innerhalb von Szenarios experimentell variierte soziale Identitäten allein kaum einen direkten Einfluss auf emotionale Reaktionen haben. Einzige Ausnahme ist die Gewalt der Fremdgruppe gegen die Eigengruppe. Auf dieses Anschlagsszenario reagieren Versuchsteilnehmer und Versuchsteilnehmerinnen im Sinne der terroristischen Logik der Provokation wütender als auf Gewalt der Eigengruppe gegen die Fremdgruppe. Der Einfluss von Geschlechter- und Gruppenidentitäten unter Täter- und Täterinnen und unter den Opfern terroristischer Gewalt zeigt sich vor allem in der Interaktion mit Geschlechteridentität und politischer Ideologie im Publikum. So wird deutlich, dass Männer sowie Personen, die sich politisch weiter rechts einordnen, mit signifikant weniger Angst und Wut auf terroristische Gewalt reagieren, die von Männern beziehungsweise der Eigengruppe verübt wird.
Investigation of Boron-Based Ionic Liquids for Energy Applications
Authors: Bilgiç Gülbahar
Published: August 2022

As a result of its electron-deficient nature, boron is utilized as the building block of ionic liquids (ILs) in energy applications (EAs) by composing a number of anions, cations, and negatively charged clusters chemically, electrochemically, and thermally. Anionic boron clusters, for example, feature distinctive polycentric bonding and are an important component of low-viscosity room temperature ILs (RTILs) utilized in electrochemical devices. In this context, recent breakthroughs in the synthesis of boron-containing ILs and various materials derived from them provide a powerful opportunity for further investigation in the field of energy research to improve and develop the properties of these boron-based ILs (BBILs). This review has provided a brief summary of boron atom or molecule-based ILs with unique features that make them ideal candidates for particular EAs. This perspective can guide further research and development of the unique properties of green and halogen-free BBILs.

Authors: Roberto Ruiz Hernández Ali , Gutierrez Cruz Adrián , Campos-Delgado Jessica
Published: August 2022

Chemical vapor deposition (CVD) represents a viable synthesis route to produce good-quality, large-area graphene films. In simple words, the technique relies on the thermal decomposition of a carbon-rich source and the further deposition of carbon atoms in a honeycomb pattern on top of a metallic catalyst film. Due to the versatility of the method, many alternatives have been explored for the synthesis of this amazing carbon 2D nanomaterial: low pressure, atmospheric pressure, roll-to-roll. Different catalysts have been explored as well; however, copper (Cu) represents the prime choice, being micrometer-thick foils the most commonly used form in CVD experiments. This chapter focuses on the production of graphene via the CVD method using copper foils, and it commences by explaining the generalities of the technique and its variants; next, a description of the method for the production of graphene using copper is included as well as the different precursors (gas, liquid, solid) that have been reported for its synthesis; we continue explaining the importance of the other gases involved in the synthesis and the efforts toward production of large-size single crystals; the obliged transfer process is reviewed, and we conclude by analyzing the advantages and the challenges of the technique.

Authors: K. Nkwabi Ally , Yoram Kavana Pius
Published: August 2022

In order to examine the bird species changes within different vegetation structures, the variations were compared between Commiphora-dominated vegetations with those of Vachellia tortilis and Vachellia robusta-dominated vegetations, and also compared the birds of grassland with those of Vachellia drepanolobium and Vachellia seyal-dominated vegetations. This study was conducted between February 2010 and April 2012. A total of 40 plots of 100 m × 100 m were established. Nonparametric Mann-Whitney U-test was used to examine differences in bird species between vegetations. Species richness estimates were obtained using the Species Diversity and Richness. A total of 171 bird species representing 103 genera, 12 orders, and 54 families were recorded. We found differences in bird species distribution whereby V. tortilis has higher bird species richness (102 species), abundance, and diversity when compared with Commiphora with 66 species and V. robusta with 59 species. These results suggest that variations in bird species abundance, diversity, and distribution could be attributed to differences in the structural diversity of vegetation. Therefore it is important to maintain different types of vegetation by keeping the frequency of fire to a minimum and prescribed fire should be employed and encouraged to control wildfire and so maintain a diversity of vegetation and birds community.

Universities of both global North and South have been changing from the traditional teaching-learning centers to cater to sustainability issues of those countries. Yet, there is a remarkable difference between the universities in the developed and the developing world. It has been found out that the different disciplines of university curricula can be integrated to address and minimize the adverse effects of unsustainability issues. The graduates of the universities will be the future leaders who have to cater to the needs and cope with the challenges of the next generation. There is a dearth of professional social workers to provide the necessary services as numerous catastrophes occur. The global society needs individuals who are equally sound in the knowledge of theory and the experience of practice. As the contemporary global issues become complex, the world needs competent social workers who can serve in different fields of practice. Social work could be the pivotal discipline in understanding common tragedies of the people to apply problem-solving model with the practitioners who are equipped with twenty-first century skills. Social work has to take a transition from a unidisciplinary to a multi- and trans-disciplinary perspective in achieving this objective.

Background: The purpose of the present study was to assess the impacts of plantar-flexors and dorsi-flexors fatigue following isokinetic contractions on postural control in nine young healthy national level judo athletes. Methods: Participants were required to stand still on a force plate with opened and closed eyes in feet together (FT) and single leg (SL) stance before (PRE) and after (POST) an isokinetic fatigue protocol. Mediolateral sway (ML sway), anteroposterior sway (AP sway), and velocity sway were calculated and used to assess the postural control. Results: Velocity sway POST was significantly (P < 0.001) higher than PRE in FT stance and SL stance. Velocity sway POST was significantly higher in the SL stance than the FT stance (P = 0.01). During eyes closed, a significant interaction postural task by fatigue for all parameters was found. All parameters increased significantly after fatigue compared to PRE. After fatigue, ML sway, AP sway, and velocity sway were significantly higher for the SL stance than the FT stance. Conclusions: Ankle muscle fatigue led to reduced postural stability during different stances in young healthy judo athletes. This effect was more accentuated when vision was removed and the base of support was reduced. Alteration of postural control depended on the difficulty of the postural stance.
Simone Weil and Emmanuel Levinas on Human Rights and the Sense of Obligation toward Others
Authors: Delhom Pascal ,   Philosophy Documentation Center

There was no dialogue between Simone Weil and Emmanuel Levinas. In many regards, however, their philosophies have much in common. Both defend a conception of human rights as rights of others and as an obligation for the self. Both understand this obligation as an obligation of attention and action for others, based on their needs and their vulnerability. Both find the source of this obligation in the transcendence of the other, and both connect it with a radical passivity of the self, who is subjected to this obligation in spite of itself. At the same time, this proximity between the two philosophers entails and reveals profound differences between them, partially due to the difference between Weil’s metaphysics of light and Levinas’s metaphysics of language. These differences concern the status of subjectivity and of its duty toward the other, as well as the idea of an acceptation of sufferance, especially of the sufferance of others.
Visão do infinito, visão no infinito: a prova ontológica e a distinção entre sentimento e ideia em Malebranche

The present article aims to analyze the relation between the finitude of the soul and the perception of the infinite in Malebranche’s philosophy. We will initially address the relationship that Malebranche establishes between the spirit and God through the simple vue proof of the existence of God, and the subsequent infinitesimal perception that follows from this immediate apprehension of the infinite. We will then turn specifically to the function that the idea of the infinite plays for Malebranchean theory of perception. On the basis of this analysis, it will become clear how the infinite is not only perceived by the spirit, but also how it becomes, after the introduction of the notion of intelligible extension, a structuring part of perception.

Digital competence is not only a desirable skill for any citizen, but also a responsibility for the training of future teachers. Using a mixed methodology combining a questionnaire based on the Common Framework for Digital Competence in Teaching and open items, this paper aims to analyse the level of digital competence of 230 future teachers (Primary and Secondary Education), as well as to explore possible differences based on some basic variables. A study is also carried out on the perceived level of digital competence and the true level of digital competence, exploring, finally, the perceptions of the uses of technology in the educational environment. The results show that the level of digital competence is intermediate, with some differences being identified depending on the dimension (with the majority considering the area of security to be the most important), as well as some variables such as age or type of access to university. Similarly, there is a self-perception of competence that is higher than real skills. Finally, an eminently instrumental use of technology is perceived, which is assumed to be part of the digital society in which teaching work is carried out.
 

La competencia digital es, al margen de una destreza deseable para cualquier ciudadano, una responsabilidad para la formación de los futuros docentes. Utilizando una metodología mixta en la que se combina un cuestionario basado en el Marco Común de Competencia Digital Docente e ítems de carácter abierto, este trabajo pretende analizar el nivel de competencia digital de 230 futuros docentes (Educación Primaria y Educación Secundaria), así como explorar posibles diferencias en base a algunas variables básicas. Asimismo, se realiza un estudio sobre el nivel de competencia digital percibida y el nivel de competencia digital real, explorando, por último, las percepciones de los usos de la tecnología en el ámbito educativo. Los resultados apuntan a que el nivel de competencia digital es intermedio, identificándose algunas diferencias en función de la dimensión (considerando de manera mayoritaria que el área de seguridad es la más importante), así como de algunas variables como la edad o el tipo de acceso a la Universidad. De igual manera, se constata una autopercepción de competencia mayor a las destrezas reales. Por último, se percibe un uso eminentemente instrumental de la tecnología, que se asume como parte de la sociedad digital en que se desarrolla la labor docente.

Este trabajo analiza el discurso de odio en los mensajes publicados en Twitter desde el 17 al 25 de mayo de 2021 durante la crisis producida por la entrada de miles de inmigrantes en la frontera del Tarajal en Ceuta. El objetivo de la investigación es realizar una clasificación temática de los mensajes que incluyen discurso de odio. Para ello, se ha empleado una metodología mixta y como resultado se han podido diferenciar seis temas, de los cuales cuatro se centran más en temas políticos, suponiendo el 80% de los mensajes, y solo el 20% de ellos se refieren a racismo e inmigración. Además, se han detectado hasta cinco campañas de origen desconocido. Este trabajo concluye que los discursos de odio se centran más en temas políticos que en la propia problemática de la inmigración, sus causas, sus consecuencias y las posibles soluciones.
