The objective of our research is to investigate the antiurolithiatic intervention of bioactive compounds of Asparagus racemosus loaded Chitosan nanoparticles (BACARNPs) on ethylene glycol engendered renal calculi in male Wister rats. The efficiency of bioactive compounds of A. racemosus (BACAR) at 800 mg/kg p.o and BACARNPs at 800 mg equivalent weight of BACAR/kg p.o was validated in ethylene glycol 0.75% (v/v) and ammonium chloride 1% (w/v) mediated renal calculi in rats. Cystone (750 mg/kg, p.o.) has been used as a standard drug. Urinary variables comprise calcium, magnesium, oxalate, phosphate, uric acid, creatinine, urine pH, urine volume, and Creatinine clearance; Serum parameters include creatinine, blood urea nitrogen (BUN), calcium and uric acid; calcium and oxalate deposition in the kidney were assessed. In vivo antioxidant parameters include lipid peroxidation, superoxide dismutase, catalase, and glutathione were determined and histopathological studies were also examined. In both control groups, a substantial increase in urinary excretion of calcium, oxalate, and their intensification in the kidney; enhanced amounts of phosphate, uric acid, and reduced magnesium levels in urine; elevated serum creatinine, BUN, calcium and uric acid; Creatinine clearance was declined were observed and normalized in treated groups. In vivo antioxidant parameters and histopathological variations reinstated to conventional form. Chitosan serves as a ligand to renal epithelial cells leads to improved agglomeration of BACAR in kidney compared to BACAR administered solitarily results in increased antiurolithiatic activity.

Obturation Techniques in Primary Teeth
Authors: Ahsana Asif  , Subramanian EMG
Published: October 2020

Dental caries is a global concern affecting children and adults. A pulpectomy is considered to be the treatment of choice to preserve the pulpally involved primary teeth. Among the various factors determining the clinical success of pulpectomy, proper obturation of the root canals plays an important role. Different obturation materials are being used for the obturation of the primary teeth root canal, which includes zinc oxide eugenol, calcium hydroxide, calcium hydroxide iodoform paste and combinations. These materials are available in different forms such as powder, powder and liquid, paste forms. Various techniques are available to introduce the obturation materials into the root canal systems. These techniques have been tried to create a three-dimensional fluid-tight seal of the root canals. This review article aims to highlight the different techniques that are being used for the obturation of primary teeth. Each technique has its advantages and disadvantages. Creation of voids within the obturation, underfilling or overfilling are the common problems that can be encountered during root canal obturation. These factors can compromise the clinical and radiographic success of pulpectomy treatment. With the current evidence, no definitive conclusions can be made to decide which is the best obturation technique in terms of clinical and radiographic success. The choice of technique selection depends on the clinician’s preference, cost-effectiveness, time consumption, ease of handling.

My Doctoral Journey: An Autoethnography of Doing Sensitive Research in a Different Cultural Context
Authors: Ramanayake Uditha
Published: October 2020

Aim/Purpose: This paper aims to provide important learning insights for doctoral students, researchers and practitioners who wish to research on sensitive topics with research participants from a significantly different culture from their own.

Background: Embarking on doctoral research in different cultural contexts presents challenges for doctoral students, especially when researching a sensitive topic.

Methodology: This paper uses an autoethnography as its research methodology.

Contribution: This paper extends the literature on doctoral researchers’ experiences of exploring the lived experiences of senior travellers who have faced major life events. Little of the previous literature on the experiences of PhD students has explored the experiences they had while researching on a sensitive topic in a different cultural context to their own. To fill this knowledge gap, this paper presents an autoethnography of my experiences.

Findings: This paper presents some critical insights into undertaking research in another culture. Its findings are outlined under the following four themes: (a) Feeling vulnerable, (b) Building rapport, (c) Preparing for the unexpected, and (d) Exploring lived experiences.

Recommendations for Practitioners: When conducting sensitive cross-cultural research, understanding researchers’ vulnerabilities, rapport-building and preparing for the unexpected are very important. The use of a visual element is beneficial for the participants in their idea generation process. Visual methods have the potential to capture the lived experiences of participants and enable them to reflect on those.

Recommendation for Researchers: Doing cross-cultural sensitive doctoral research poses a number of methodological and practical challenges. It was very important to gain a wider cultural understanding of the country and its people in my cross-cultural doctoral research. To this end, this paper suggests that future doctoral researchers consider volunteering with the community as a way to gain understanding of the research context when preparing to undertake cross-cultural research.

Impact on Society: The findings support the importance of cultural sensitivity when doing cross-cultural research.

Future Research: Future research could be conducted in a different cultural setting to reveal whether the key themes identified here are universal.
Shear Strength of Reinforced Concrete Columns Retrofitted by Glass Fiber Reinforced Polyurea
Authors: Song Jun-Hyeok , Lee Eun-Taik , Eun Hee-Chang
Published: October 2020

Aged structures and structures constructed based on outdated non-seismic design codes should be retrofitted to enhance their strength, ductility, and durability. This study evaluates the structural performance of reinforced concrete (RC) columns enhanced via polyurea or glass fiber reinforced polyurea (GFRPU) strengthening. Four RC column specimens, including a reference specimen (an unstrengthened column), were tested to evaluate the parameters of the strengthening materials and the strengthened area. The tests were carried out under a combined constant axial compressive load and quasi-static cyclic loading. The experimental results show that the composite strengthening provides lateral confinement to the columns and leads to enhanced ductility, shear-resistance capacity, and dissipated energy. The shear strength provided by the composites depends on the degree of lateral confinement achieved by the composite coating. The specimens finally failed through the development of diagonal tension cracks within the potential plastic hinge regions. The specimen treated with GFRPU strengthening showed greater strength and dissipated more energy than the specimen treated with polyurea strengthening. Furthermore, by modifying ATC-40, this study proposed an equation to estimate the shear capacity provided by the composites.
Effect of Fibrous Jacket on Behavior of RC Columns
Authors: Jassim Wathiq , Chassib Samir M.
Published: October 2020

This paper presented an extensive study about the strengthening of RC square short columns with high strength concrete jackets reinforced with steel fiber. The aim of this study is to investigate the effect of confinement by fibrous jacket on the behavior of RC column. A comparative study is performed on 23 square columns (six of them were unconfined columns where the remaining seventeen were confined columns) with varied parameters such as steel fibers ratio and type, jacket thickness, partial and full strengthening, type of confining jacket (hoop and composite), use of epoxy as bond material between the concrete column and strengthening jacket, and length parameter. The test results showed that the strengthened columns showed a significant improvement in the ultimate stress, load-carrying capacity, maximum strain, ductility, and energy absorption. Increase the steel fibers ratio (1, 1.5 and 2%) increased the ultimate stress by (22.5, 12.3 and 12.5%) respectively. The use of epoxy as bond material enhanced the ultimate stress by an average improvement by (55%). Composite case in the strengthening enhanced the load-carrying capacity larger than hoop case by (28.7 and 42%) for FRC jackets with hooked and straight fibers respectively but in case of stress capacity, hoop jacket carries stresses more than composite according to the stressed cross-sectional area. Increase jacket thickness (25 and 35 mm) enhanced the ultimate stress by (28.7 and 15.5%) respectively. Partial strengthening has a good enhancement in the ultimate load but was less than full strengthening. Increase the length by (25 cm) decreased the enhancement in load capacity of the column with hoop jacket by (45.3%). Concrete jackets enhanced Energy absorption and ductility which improved the deformation capacity. The compressive behavior of stub concrete columns was also modeled, simulated, and analyzed numerically by a 3D nonlinear finite element model. The verification process was performed against the reported data of the experimental test which proved the results of experimental results and showed a good agreement between experimental and numerical outcomes.

Authors: Moura Luciano Raizer , Kohl Holger
Published: October 2020

The article presents a comparative analysis of maturity level in Industry 4.0, of Brazilian companies with German Industry, seeking to identify learning opportunities to increase competitiveness. It was used the maturity model in Industry 4.0 developed by VDMA (German Mechanical Engineering Industry Association), applied to German companies, serving as benchmark. The same model was applied to Brazilian companies, from the State of Espírito Santo, located in the most developed region of the country, but with lower industrial density, and which has great challenges to increase its participation in the national and international markets. A field research was carried out with 46 industries, which participated in workshops to understand the fundamentals and to evaluate the maturity level in Industry 4.0. The individual results were processed by the platform of VDMA, indicating the levels in six dimensions of the model and the general result on a scale of 0 to 5. The results of all companies were tabulated, allowing the comparison with the research carried out with German companies. The study showed that, on average, Brazilian companies have the same level of maturity of German companies in readiness for Industry 4.0, with grade 0.9 in a scale of 0 to 5. But, there are significant differences in compared dimensions. 5.6% of German companies are at the advanced level in Industry 4.0, especially the technology developers, while Brazilian companies studied are still at the most basic levels. Both Industries are skeptical about investments in Industry 4.0 and the level of evaluation on Strategy dimension is still low. The comparison of expectations and difficulties allowed identify essential points to support these companies to follow the way to Industry 4.0.

POEAM – A Method for the Part Orientation Evaluation for Additive Manufacturing
Authors: Jung Simon , Peetz Sebastian , Koch Michael
Published: October 2020

In the industrial application of additive manufacturing processes, a significant amount of time and resources are dedicated to the orientation and pre-print setup of the geometry. Steps such as the generation of support structures and the process simulation are among the most time-consuming. For the thorough assessment of an orientation of a given geometry, even more criteria, like print time or surface quality, need to be considered. POEAM proposes a method for an efficient assessment of a set of orientations, by means of well formulated criteria and an early elimination of insufficient orientations. The goal is to narrow the search field, so costly preparation steps will only be performed on orientations that promise a superior end result. Furthermore, POEAM is an automated process, which means it can be performed with minimal human interaction, resulting in an optimum regarding cost-efficiency and evaluation time. The method was applied to a representative geometry and has shown results that confirm the above-mentioned advantages.
On the Role of Ethics in Shaping Technology Development
Authors: Vargas-Elizondo C.
Published: October 2020

Important changes are taking place, currently, regarding the role of ethics in technology, particularly, in the context of the fourth industrial revolution.  The adoption by the General Assembly of United Nations of the resolution A/RES/70/1 on September 27th, 2015, entitled "Transforming our world: the 2030 Agenda for Sustainable Development", better known as "sustainable development goals", is making that different international organisations and countries adopt it as the minimum reference ethical framework for assuring that this revolution in course supports and contributes to achieving these goals. To better understand these changes, it is important to make a historical reference to how technology and the role of ethics were understood during the past 50 years. In this paper, I take as reference the influencing book “The Challenge Presented to Cultures by Science and Technology” (1977) of the Genevan philosopher Jean Ladriére, some ethical proposals made during the '90s, to end with some recent European Union (2019) and World Economic Forum (2018) ethical proposals. I conclude that there are continuities and discontinuities, first in the conception of science and technology in Jean Ladriére and others, and how recent proposals are approaching the issue, second on the role of ethics in this fascinating and revolutionary process. However, we may envisage a radical transformation of the conception of technology in the context of the worldwide request of shaping the fourth industrial revolution.
Comparitive consideration of linguocultural types “father”: “pastor” in Russian and American linguocultures
Authors: Bobyreva Ekaterina V.
Published: October 2020

Problem of linguocultural types has been one of the important current directions of research. The
article deals with the linguocultural types “father” (in Russian linguoculture) and “pastor” (in American linguoculture), their comparative consideration is conducted. Comparative consideration of linguo-cultural types
“father” and “pastor” seems to be important for linguoculturology, linguoconcepology and general theory of
discourse because it allows to add to the general theory of linguocultural types information about nationally
specific types in Russian and American linguocultures. The relevance of the study can be explained, firstly, by
the significance of the linguo-cultural types “father” and “pastor” for creation of a comprehensive picture of
religious discourse, secondly, linguocultural types “father” and “pastor” are important not only in the sphere
of a particular social institution – religious discourse – but have important place in national Russian and
American linguocultures in general. It seems important to conduct comparative consideration of linguocultural
types close in content and significance in different linguocultures in order to define their general characteristics and differences and, as a result to improve process of intercultural communication of the representatives
of different linguocultures. The general notion for the linguocultural types under consideration is the notion
“clergyman” which has general characteristics of the linguotypes considered. Comparative consideration of
linguocultural types “father” and “pastor” was conducted according to such characteristics as appearance, age,
gender, occupation, family, values. Study showed that linguocultural type is greatly influenced by national specifics of linguocultural type. The material was provided by samples of sermons, as well as guides to worship in
Russian and English. To conduct the study methods of semantic, contextual, comparative analysis were used.
English Neologisms: knowledge domains represented by them, principles and mechanisms of their creation
Authors: Liudmila V. Babina
Published: October 2020

The article considers English neologisms from the position of cognitive approach, which involves identifying knowledge domains represented by such words, describing the principles that ensure the creation of new knowledge based on existing ones. In addition, the author analyzes some cognitive mechanisms for creating neologisms that arise as a result of reinterpretation. The study was performed on the material of new language units selected on sites dedicated to English neologisms, using a continuous sampling method. The author uses a set of methods, the main of which are methods of conceptual and definition analysis and cognitive modeling. As a result of the research, it was found that neologisms represent knowledge domains that traditionally arouse interest (politics, economics, and the field of consumption). At the same time, there are many neologisms that reflect knowledge about computer and digital technologies and various types of human interaction with the virtual world. It is determined that neologisms that appear as a result of reinterpretation are created by cognitive mechanisms of “conceptual metaphor”, “conceptual metonymy”, “conceptual metaphtonymy”, and “concretization”. Neologisms are formed by the following metaphorical cognitive models: HUMAN BEING – ARTEFACT, ARTEFACT – ANIMAL, ARTEFACT – ARTEFACT, ABSTRACT – PHYSICAL, VIRTUAL – REAL, ANIMAL – ANIMAL, and HUMAN BEING – ANIMAL, which are used both when reinterpreting simple and compound words. The principles that determine the cognitive processes of creating neologisms that represent knowledge based on existing language structures are also described: principle of economy, principle of vividness and subjectivity, principle of using new interpretive realities, principle of remotivation.

Published: October 2020

Tujuan artikel ini, yaitu untuk mengkaji kearifan lokal dan budaya Betawi (upacara adat perkawinan dan kuliner Betawi) serta mengetahui implementasi Pendekatan Kearifan Lokal dan Budaya Betawi dalam pembelajaran Biologi. Pendekatan ini selanjutnya disingkat Pendekatan KALBU. Metode penelitian menggunakan kajian studi pustaka dan observasi langsung di Perkampungan Budaya Setu Babakan. Kompetensi pengetahuan Kebudayaan Betawi yang dapat diintegrasikan dalam Biologi Kelas X, yaitu topik Kingdom Plantae dan Kingdom Animalia. Hal ini karena kearifan lokal dan budaya Betawi memanfaatkan tumbuhan dan hewan dalam kebudayaannya. Pemanfaatan tumbuhan dan hewan tampak pada upacara perkawinan adat Betawi dan kuliner Betawi. Species yang digunakan sebagian besar adalah tumbuhan dari kelompok Eudicots, Monocots, dan Magnoliids. Species hewan biasanya digunakan sebagai pelengkap, seperti dari kelompok Aves dan Crustacea. Pendekatan KALBU dapat diintegrasikan dengan model pembelajaran berbasis proyek. Salah satu proyek yang dapat diterapkan adalah video pembelajaran mengenai kearifan lokal dan budaya Betawi di mana berkaitan dengan materi Kingdom Plantae dan Kingdom Animalia. Potensi kebudayaan Betawi dapat dijadikan alternatif pendekatan pembelajaran Kearifan Lokal dan Budaya (KALBU) pada Kurikulum 2013 karena pendekatan ini dapat mengukur kompetensi, antara lain sikap spiritual, sikap sosial, pengetahuan, dan keterampilan.
