EXPERIMENTAL STUDY ON MECHANICAL PROPERTIES OF CORRUGATED CEMENT SLATE BOARD USED FOR OVER 30 YEARS
Authors: Sadamoto Mai , Kaita Tatsumasa , Katsui Yuji , Liu Mao
Published: January 2023

The corrugated cement slate board which includes asbestos fiber had been generally used as wall and roof members for many plant buildings, because it has high fire and water resistance. From this fact, it is thought that a huge number of same type slate boards still continue to use throughout Japan. Conversely, the accident reports for deteriorated slate board are increasing such as flying apart by collision when strong wind and breaking by worker’s weight. Therefore, it will be required technical diagnosis based on remaining thickness for drawing reasonable maintenance plan of aged slate boards. In this study, the bending test and weight-drop test are carried out for clarifying between the mechanical properties and remaining thickness for 16+12 corrugated cement slate boards which were dismantled from plant buildings at coastal area in Seto Inland Sea. These slate boards are classified large or small wave shapes and had been used for over 30 years. The remaining bending strength and stiffness of these slate boards were compared with current JIS standards. From the experimental results, the main conclusions are as follows: 1) It will be thought that if the remaining thickness was decreased more than 10% comparing manufactured initial thickness (6.3mm), the remaining bending strength may not be able to satisfy current JIS standards. In this case, the severe through-hole may be caused by any external impactive force. 2) The stiffness and impact resistance of large wave slate which had been exposed for over 30 years as roof member may decrease considerably.

Authors: Camille Christophe , Kahagala Hewage Dayani , Mirza Olivia , Clarke Todd
Published: January 2023

The addition of fibers to concrete is well known for enhancing the tensile and ductility performances through an effective fiber network intersecting the propagation of cracks. However, the class, quantity and properties of the individual fibers fundamentally govern the flexural behavior, resulting in either post-cracking softening or hardening response. Moreover, previous studies have shown that while steel and synthetic fibers may provide comparable improvement of the concrete’s mechanical properties, their respective involvement occurs at different crack widths to perform best in particular applications. In this paper, more consideration is given to macro synthetic fibers that are commonly preferred over steel fibers because of their corrosion resistance and sustainable sourcing pathway (i.e., recycled waste plastics). Thus, this work investigates the post-peak flexural behavior of macro synthetic fiber reinforced concrete (MSFRC) using two fiber types at different volume dosages. Accordingly, the novelty of this paper is to identify the critical crack states of each fiber type and dosages that provide the potential engineering benefits of a pioneering design and application.

Authors: Supit Steve Wilben Macquarie , Priyono Priyono , Sirun Artian , Astanto Mireikel
Published: January 2023

This study reports the effects of using plastic waste type PET (Polyethylene Terephthalate) as sand replacement in the manufacture of pervious concrete paving block to be applied for low-traffic volume roads, parking areas and pedestrian walkways. The PET plastic aggregates were prepared through the pre-heated method under 150-180°C and then crushed into pieces to partially replace the sand content in concrete paving block mixtures at percentage of 5%, 10%, 20% and 30% by wt. of total sand. The experimental studies were conducted on concrete paving block (size 210x110x60 mm3) containing PET plastic waste aggregate. The coarse aggregate to cement ratio used was 4:1 while the fine aggregate to cement ratio was 1.5:1. The properties of concrete paving block specimens were evaluated based on the compressive strength, flexural strength, and void ratio results after curing. From the results obtained, it can be concluded that the maximum of percentage when using plastic waste type PET was 5% by wt. of sand. The mechanical properties and void ratio of the concrete paving block showed that the utilization of plastic waste type PET as construction material has potential contribution in improving the pavement structure and offering sustainable solution on environmental issue.

Authors: Kita Eisuke , Ishizawa Daisuke , Tamaki Tatsuhiro
Published: January 2023

Recently, traffic congestion has become a serious social problem all over the world as the number of vehicles increases. Traffic congestion causes economic loss, air pollution and traffic accident. For solving this problem, study on vehicle platooning using the technology of inter-vehicle communication has been studied widely. The vehicle platoon is a technique of grouping vehicles with a short inter-vehicle distance with help of electric and mechanical control, which is expected to reduce traffic congestion, and save labor and energy. However, when realizing platooning in the real world, the adequate control algorithm of the velocity of the vehicles in the platoon is necessary. In this study, the traffic situation is assumed so that the vehicles in the platoon and the other ones are travelling on the road. The vehicles in the platoon can keep their distance short by the help of inter-vehicle communication. The purpose of this study is to control the vehicle platoon safely without causing collision between vehicles when the sudden deceleration of the general vehicle in the platoon. The simulation and the experimental results showed that the proposal algorithms could control the vehicles without collision with the other vehicles and running backwards, while maintaining control of the velocity of the vehicles in the platoon.
STRAIN BEHAVIOR UNDER ALTERNATE REPEATED LOADING WITH CONSTANT STRESS AMPLITUDE AFTER LARGE TENSION OR SHEAR
Authors: KATO YASUYUKI
Published: January 2023

This research paper describes elasto-plastic behaviors obtained under repeated loading after applying a large pre-deformation. In our previous research, the yield surface shape under finite deformation has been investigated to the test specimens of tough pitch copper using Natural Strain theory that is a reasonable for representing a large deformation. Moreover, the variation of yield stress with increase of the number of repetitions has been investigated when the repeated loadings are applied to the test specimens that the anisotropy for yield surface had already been formed. In those studies, the elasto-plastic behaviors measured under constant strain amplitude have been mainly examined, however, behaviors for constant stress amplitude have not yet been researched in detail. Therefore, in the present study, the strain behaviors obtained under repeated loadings with constant stress amplitude are investigated using specimens that have already undergone the large pre-deformations for tension or simple shear. Then, the relation between these strains’ behaviors and the anisotropy for the yield surface shape formed by large pre-deformation is revealed in this study.
SIMPLIFIED METHOD FOR PREDICTION OF VIBRATION BEHAVIOR OF STEEL-CONCRETE COMPOSITE FLOOR SUBJECTED TO GENERAL LOADING
Authors: Barbade Chaitanya , Satish Kumar S. R.
Published: January 2023

Vibration serviceability problems have often been encountered in steel-concrete composite floors due to their long span and lightweight nature and have low damping depending on the occupancy. These are being used for various applications and hence are being subjected to different dynamic loads such as those due to human excitations and mechanical vibrations. Thus, it becomes necessary to predict the vibration behaviour at the design stage itself to avoid problematic floors. Previous researchers have extensively studied and presented simplified equations to understand the behaviour of floors subjected to human excitations such as walking, jumping, dancing, etc., but these equations are based on the beam mode of vibration. This paper presents a method that captures the behaviour of the floor alone subjected to a certain frequency and a general dynamic load. A novel displacement-controlled test to predict natural frequency was conducted in which the floor was subjected to vibration with a certain displacement over a range of forcing frequencies away from the natural frequency and the results conclude that the method shows good agreement with the traditional heel drop test and can be used for the purpose.

Authors: Jeong Yeongseok , lim chhoung , Kwon Minho
Published: January 2023

Fiber Reinforced Polymer (FRP) material which exhibits light weight, high strength, and high stiffness was developed. It has been actively experimentally utilized in the construction field. FRP fibers are mostly made of Carbon, Aramid, and Glass. However, another material named basalt has been recently developed because it is more eco-friendly compared to the existing materials. Therefore, in this study, a four-point bending test was performed on reinforced concrete (RC) beams strengthened with CFRP and BFRP grids. As a result, the behavior changes of the specimen were observed due to the differences of the material properties. It confirmed that the specimen reinforced with BFRP grid was more ductile than that reinforced with CFRP grid even after the yield of rebar. It is because BFRP material possesses lower stiffness and longer elongation compared to CFRP. Moreover, reinforcing with BFRP can prevent brittle failure of the beam compared to CFRP even CFRP is more expensive and harmful to environment.

Authors: Sinha Ajay Kumar , Anand Praveen
Published: January 2023

The study presents the effectiveness of Reinforced Concrete (RC) jacketed columns in enhancing the seismic performance of a five-story RC frame. The performance of the structure is examined using a non-linear static method also known as pushover analysis. The retrofitting approach used in this study is a local level approach and its effect on the global behavior of the frame. SAP 2000 has been used to perform the analysis for the frames before and after jacketing the columns. The sequence of hinges formation has been studied for both frames. The change in ductility capacity and elastic stiffness before and after jacketing of the columns is obtained using bilinear curves. Both the structural parameters calculated for existing and jacketed structures showed a substantial increase in their respective values after jacketing. Variation of base shear for both the frames is obtained using capacity curves or pushover curves. The pushover curve obtained as a result of static nonlinear analysis indicated a considerable increase in the strength of the jacketed frame which is almost double the capacity of the existing frame.

Published: January 2023

There is a global shift towards circular economies, which concentrate on reducing waste, extending the useful life of materials or transforming wastes into another useful material. Every year, Australia generates around 2.54 million tonnes (Mt) of waste plastics, 1.16 Mt of waste glass, and 0.45 Mt of end-of-life tires. Of these about 85% of the plastic, 41% of the glass, and 24% of the tires are disposed of in either licensed or unlicensed landfills at significant financial and environmental cost. The 2021 ban on the export of mixed plastics, glass, and tires has put tremendous pressure on Australia's resource recovery sector, as around 500,000 tonnes of additional landfill waste per year must be processed onshore as a consequence. This paper discusses the technical and environmental challenges associated with these landfill wastes and determines whether they can be made or recreated into useful resources. A summary of the current initiatives in value-adding landfill waste for civil engineering and construction is also presented. The findings suggest that using advanced engineering and manufacturing to develop technology from these wastes is an effective way of managing and adding value to these materials that strongly supports Australia's Circular Economy mission, ReMade in Australia campaign, and Net-Zero Emissions Plan by 2050.
PL Morse theory in low dimensions
Authors: Grunert Romain , Kühnel Wolfgang , Rote Günter
Published: January 2023

We discuss a PL analog of Morse theory for PL manifolds. There are several notions of regular and critical points. A point is homologically regular if the homology does not change when passing through its level; it is strongly regular if the function can serve as one coordinate in a chart. Several criteria for strong regularity are presented. In particular, we show that in dimensions d ≤ 4 a homologically regular point on a PL d-manifold is always strongly regular. Examples show that this fails in higher dimensions d ≥ 5. One of our constructions involves an embedding of the dunce hat into 4-space and Mazur’s contractible 4-manifold. Finally, decidability questions in this context are discussed.
Determination of parathyroid hormone: from radioimmunoassay to LCMS/MS
Authors: Cavalier Etienne
Published: January 2023

Parathyroid hormone (PTH) determination is of paramount importance for the exploration of diseases related with calcium metabolism and for the follow-up of patients suffering from bone and mineral disorders associated with chronic kidney diseases (CKD-MBD). Unfortunately, the biologically active form of PTH, i.e. 1–84 PTH, circulates in the blood stream with many fragments and post-translationally modified forms, which decreases the specificity of immunoassays. The assays used to measure PTH, either from 2nd or 3rd generation, are not standardised, which may lead to interpretation errors and clinical consequences. Reference ranges for PTH have neither been always correctly established and the stability of the peptide is also a matter of concern. Fortunately, these last years, newer techniques using mass spectrometry (either high resolution or triple quadripole) coupled with liquid chromatography have been developed, which will help to standardise the different assays. Indeed, PTH assays standardisation is one of the task of the IFCC Committee for Bone Metabolism. Such standardisation will allow a better consistency in the interpretation of the results and will promote studies aiming at the establishment of correct reference ranges.
LMS-based continuous reference percentiles for 14 laboratory parameters in the CALIPER cohort of healthy children and adolescents
Authors: Wilson Siobhan M. , Bohn Mary Kathryn , Madsen Andre , Hundhausen Thomas , Adeli Khosrow
Published: January 2023

Objectives

Marked physiological changes in growth and development present challenges in defining pediatric reference intervals for biomarkers of health and disease. Lambda, Mu, and Sigma (LMS)-based statistical modeling provides a continuous normal distribution by negating skewness and variation, and is commonly used to establish growth charts. Such LMS reference curves are suggested to enhance laboratory test result interpretation. The current study establishes LMS-based continuous reference percentiles for 14 biomarkers in the CALIPER cohort of healthy children and adolescents.

Methods

Data from healthy children and adolescents aged 1–<19 years were used to establish continuous reference percentiles using a novel LMS-based statistical method, including 2.5th, 25th, 50th, 75th, and 97.5th percentiles. The LMS approach applies a Box-Cox data transformation and summarizes continuous distributions by age via three curves: skewness (Lambda), median (Mu), and coefficient of variation (Sigma).

Results

LMS-based percentiles and z-scores were generated for 14 common pediatric biomarkers that demonstrate dynamic concentration patterns with age (e.g., alkaline phosphatase) and/or wherein the magnitude of difference from the population mean may be clinically relevant (e.g., triglycerides). The LMS model captured age- and sex-specific distributions accurately and was not substantially influenced by outlying points.

Conclusions

This is the first study to establish LMS-based continuous reference percentiles for biochemical markers in a healthy Canadian pediatric population. The current LMS-based approach builds upon previous continuous reference interval models by providing graded percentiles to improve test result interpretation, particularly with repeated measures over time. This method may assist in facilitating a patient-centered approach to laboratory medicine.
Social Connection when Physically Isolated: Family Experiences in Using Video Calls
Authors: Kacane Ilze , Hernández-Serrano Maria Jose
Published: January 2023

Digital (video) calls have become a significant tool during the challenging times marked by the COVID-19 pandemic. The article focuses on the perceived functionality of video calls for maintaining social contacts and overcoming loneliness in celebrating family festivities limited by physical distance policies. The qualitative study conducted at the end of 2021 in Latvia and Spain examines families’ cultural socialisation via digital tools and, based on data obtained from semi-structured in-depth interviews, assesses the users’ digital experiences in celebrating Christmas and the New Year from retrospective and prospective standpoints. The obtained data revealed that although digital interactions were acknowledged as an alternative means for ensuring togetherness, preserving and facilitating emotional connection, and experiencing a feeling of belonging and shared identity, they were perceived as the context of exception. The findings complement existing studies that the pandemic contributed to bridging the digital gap among generations with coordinated and negotiated conceptions of the functionality of digital tools. Video calls ensured a sense of social and emotional connectedness and inspired the appearance of virtual celebration ideas.
Spin–orbit coupling induced by ascorbic acid crystals
Authors: Grenapin Florence , D’Errico Alessio , Karimi Ebrahim
Published: January 2023

Some anisotropic materials form semicrystalline structures, called spherulites, when observed in a polarisation microscope, exhibit a characteristic “maltese-cross”-like pattern. While this observation has been hitherto considered as a tool to characterize these materials, we show that these patterns are associated with a strong light’s spin–orbit coupling induced by the spherulite structures. We experimentally demonstrate these effects using samples of crystallized ascorbic acid and observing the creation of optical vortices in transmitted laser beams, as well as the formation of inhomogeneous polarisation patterns. Our findings suggest the use of some spherulites based on other materials in frequency ranges, e.g. in the THz domain, where polarisation and spatial shaping of electromagnetic radiation is still a challenging task.
Purcell enhancement and polarization control of single-photon emitters in monolayer WSe2 using dielectric nanoantennas
Authors: Azzam Shaimaa I. , Parto Kamyar , Moody Galan
Published: January 2023

Two-dimensional (2D) materials have shown great promise as hosts for high-purity deterministic single-photon sources. In the last few years, the underlying physics of single photon emission in 2D materials have been uncovered, and their optical properties have been improved to meet criteria for a variety of quantum technologies and applications. In this work, we take advantage of the unique characteristics of dielectric nanoantennas in manipulating the electromagnetic response on a sub-wavelength scale to localize and control defect-based single-photon emitters (SPEs) in 2D layered materials. We show that dielectric nanoantennas are capable of inducing high Purcell enhancement >20 and therefore brighter single-photon emission, which is characterized by a reduction of the emitters’ radiative lifetimes and enhancement of their brightness by more than an order of magnitude. We demonstrate that the sub-wavelength-scale dielectric nanoantennas can be designed to also impose a predetermined strain profile that determines the confinement potential of the SPE, leading to robust control over the optical polarization with up to 94% extinction ratio. The combination of large Purcell enhancement, polarization orientation, and site control through strain engineering demonstrates the advantages and unique capabilities of dielectric nanoantennas for enhancing the quantum optical properties of 2D SPEs for quantum information technologies.
Three-dimensionally reconfigurable focusing of laser by mechanically tunable metalens doublet with built-in holograms for alignment
Authors: Jung Joonkyo , Kim Hyeonhee , Shin Jonghwa
Published: January 2023

Metalenses have potential to replace various bulky conventional optical elements with ultrathin nanostructure arrays. In particular, active metalenses with reconfigurable focusing capability have attracted considerable interest from the academic and industrial communities. However, their tuning range is currently restricted by limited material properties and fabrication difficulties. Here, a hybrid optical system capable of three-dimensional relocation of a focal spot is proposed and experimentally demonstrated. The system comprises a mechanically actuated passive metalens doublet that can be easily fabricated with commonly available materials and processes. An incident laser can be focused to a desired point in three-dimensional space simply by rotating two metalenses or changing their separation. In addition, exploiting the polarization-multiplexing capability of metasurfaces, a hologram is incorporated to the metalenses to guide rotational and positional alignment of two metasurfaces. The ease of fabrication and alignment provided by this approach could widen its application to many practical fields.

Published: January 2023

Glasses-free three-dimensional (3D) display has attracted wide interest for providing stereoscopic virtual contents with depth cues. However, how to achieve high spatial and angular resolution while keeping ultrawide field of view (FOV) remains a significant challenge in 3D display. Here, we propose a light field 3D display with space-variant resolution for non-uniform distribution of information and energy. The spatial resolution of each view is modulated according to watching habit. A large-scale combination of pixelated 1D and 2D metagratings is used to manipulate dot and horizontal line views. With the joint modulation of pixel density and view arrangement, the information density and illuminance of high-demand views are at most 5.6 times and 16 times that of low-demand views, respectively. Furthermore, a full-color and video rate light field 3D display with non-uniform information distribution is demonstrated. The prototype provides 3D images with a high spatial resolution of 119.6 pixels per inch and a high angular resolution of 0.25 views per degree in the high-demand views. An ultrawide viewing angle of 140° is also provided. The proposed light field 3D display does not require ultrahigh-resolution display panels and has form factors of thin and light. Thus, it has the potential to be used in portable electronics, window display, exhibition display, as well as tabletop display.
Mechanisms of cholera transmission via environment in India and Bangladesh: state of the science review

Published: January 2023

Objectives

Cholera has a long history in India and Bangladesh, the region where six out of the past seven global pandemics have been seeded. The changing climate and growing population have led to global cholera cases remaining high despite a consistent improvement in the access to clean water and sanitation. We aim to provide a holistic overview of variables influencing environmental cholera transmission within the context of India and Bangladesh, with a focus on the mechanisms by which they act.

Content

We identified 56 relevant texts (Bangladesh n = 40, India n = 7, Other n = 5). The results of the review found that cholera transmission is associated with several socio-economic and environmental factors, each associated variable is suggested to have at least one mediating mechanism. Increases in ambient temperature and coastal sea surface temperature support cholera transmission via increases in plankton and a preference of Vibrio cholerae for warmer waters. Increased rainfall can potentially support or reduce transmission via several mechanisms.

Summary and outlook

Common issues in the literature are co-variance of seasonal factors, limited access to high quality cholera data, high research bias towards research in Dhaka and Matlab (Bangladesh). A specific and detailed understanding of the relationship between SST and cholera incidence remains unclear.

Published: January 2023

The opinions expressed in the press regarding education in this period have two directions: on the one hand, they criticize the scarcity and poor material conditions of schools, and on the other hand, they try to create an awareness that serves to transmit their own ideology but what about non-formal education? Parallel to this educational universe, non-regulated education is developed, outside legal limits and promoted by the most humanistic social agents within the context of charity. This article aims to show some practices of this teaching, such as music academies, popular libraries, night and Sunday schools for Catholic workers in the city of Elche and the Singer Company, under the gaze of historical sociology.

The present investigation arises to know the educational reality related to the existence (or not) of sexist traits in boys and girls in the Early Childhood and Primary Education stage. It will be analyzed whether the family, educational and social context influences the children's conception of these traits, carrying out quantitative questionnaires for infant, first, second and third cycle primary school students and teachers, to find out their opinions and their approach in schools. These forms will be made by Google Form for the primary stage and teachers and paper questionnaires for the infant stage, aimed at corroborating or not, the problem, the objectives and the hypotheses raised, to two concerted schools, SAFA from Úbeda and from Villanueva del Arzobispo and a public one, Father Manjón de Sorihuela del Guadalimar. From the analysis of the results, we reach a series of conclusions that confirm that there are indeed sexist conceptions of gender both in Early Childhood Education and in Primary Education, and that despite the fact that there is a large part of the teaching staff committed to this issue, there is still much work to be done, being of special importance the cooperation between country, family, society and school.

The text presents the theoretical discussion of the formative proposal of Ignatian pedagogy in higher education, a seal of commitment to educational spirituality generated from the identity, principles and values ​​of its founder, Saint Ignatius of Loyola, to the common educational project emanating from the Ignatian Pedagogy and the pedagogical proposal for Jesuit higher education, for the education of professionals committed to the country, trained in human, ethical and Christian values, conscientious, competent, committed and compassionate citizens. This view is important for the right to a comprehensive quality education. The documentary analysis carried out consolidates the validity of the formative proposal of Ignatian Pedagogy, a transformative educational-pedagogical model in higher education and the commitment of the Rafael Landívar University to comprehensive quality education. Quality in higher education refers to educational quality standards as a need and right for a change in the 21st century university that establishes the appropriate conditions to promote more student-centered learning and use of innovative teaching methods. This requires curricular and technological adaptations, the need for teacher training, and the reinforcement of skills in students and teachers. The value of pedagogical skills in university teaching pursues the mastery of specific skills and abilities for good teaching performance. In the pedagogical proposal for Jesuit higher education, teaching and research are the center of interest of university policies; research for the creation of knowledge and teaching for its dissemination. In Ignatian Pedagogy these two functions have a special meaning in student learning and teaching performance. The contributions emphasize human formation, didactic application and social commitment. They allow the understanding and value of the formative intentionality of Ignatian pedagogy, the integrality of formation, the didactic concretion, and the formative research processes.

Сommunicative-pragmatic signs and functions of the scientific style of modern Ukrainian literary language
Authors:   Institute of the Ukrainian Language of the National Academy of Sciences of Ukraine, Kotsʹ Tetiana
Published: January 2023

The article analyzes the conceptual paradigm of scientific style as a type of literary language from the point of view of the concept of encyclopedic coverage of the terminological system of Ukrainian linguistic stylistics. Particular attention is paid to the establishment of communicative and pragmatic features, functions of the scientific style and its varieties (scientific-educational, popular science, scientific-journalistic substyles), coverage of theoretical issues of historiosophy and historiography of style in Ukrainian linguistics. In the system of concepts, literature is considered as the main category and the term as a differential unit of scientific texts. The concept of scientific style is systematized in the context of the typology of language thinking, the establishment of a view on the history of the literary language and its styles as phenomena closely related to the philosophy of culture, the development of national consciousness. The integrative aspect proposed in the article complements the structural-level analysis of the texts and involves the interpretation of the style category in the context of the typology of language thinking, the definition of concepts subordinate to it, the establishment of a view on the history of the literary language and its styles as phenomena closely related to the philosophy of culture, the development of national consciousness. The conceptual paradigm of scientific style requires the establishment of hypero-hyponymic connections and an encyclopedic (short and at the same time informatively comprehensive) substantiation of the status of concepts, the establishment of their differential features and the highlighting of the historiography of style in Ukrainian linguistics, which will be an intermediate summary of the acquisitions in this field of Ukrainian linguistics and at the same time make it accessible them for the wider philological community. The scientific style serves the needs of important spheres of the Ukrainian language spaceeducation and science, the development of which testifies to the intellectual level of the nation. Keywords: scientific style, scientific text, concepts, scientific and educational sub-style, popular scientific sub-style, scientific and journalistic sub-style
Espacio público, la necesidad de la organización vecinal para recuperarlo. El caso de la colonia San Manuel, Puebla, México
Authors: Montes Pesquera Juan Carlos , Flores Lucero María de Lourdes , Guevara Romero María Lourdes
Published: January 2023

El espacio público es un lugar de encuentro, interacción y cohesión para el desarrollo de diversas actividades de los habitantes. Sin embargo, la desatención y escasez de acciones para su mejoramiento ha conllevado a su deterioro y a su pérdida paulatina. Este es el caso de la colonia San Manuel, ubicada al suroriente de Puebla, México, a través de la cual se muestra como las malas condiciones del espacio público no solo han derivado en su cuasi abandono, sino que se ha convertido en un lugar propicio para delinquir. Asimismo, se detectan cuáles son las acciones realizadas por los vecinos organizados para disminuir este problema. La metodología es cualitativa y se implementó a través de cuatro técnicas: revisión documental, entrevistas semidirigidas, reuniones vecinales y recorridos de campo. Entre los resultados destacan que recuperar el espacio público puede mutar positivamente un espacio que no se utiliza y evita el riesgo de que se convirtiera en un escenario apto para delinquir. Por esto es necesaria y urgente la acción conjunta vecinal sin des responsabilizar a los gobiernos locales. Sin embargo, el proceso puede aletargarse cuando la organización es débil, desarticulada y con poca comunicación con el sector público, por lo que es necesario establecer estrategias de comunicación para mejorar la organización. Para ello las instituciones de educación superior pueden ayudar a detonar acciones de trabajo colaborativo entre los sectores público y social.

The table olive industry produces a large amount of wastewater that can be expensive to be treated and harmful to the environment. This study aimed to find a way to reuse brine water from the production of black and green table olive brines from Bejaia and Mascara of the Sigoise cultivar in order to create a valuable byproduct and con-tribute to sustainable development. In this context, the high-performance liquid chromatography–diode-array detection (HPLC-DAD) analysis revealed the highest concentration of hydroxytyrosol (4-(2-dihydroxy phenyl ethanol); 69.67 mg/100 mg) for green table olive brines of Mascara (EOGM) and tyrosol (Ty) (28.8 mg/100 mg) for black table olive brines of Bejaia (EOBB). Presence of polyphenols and ortho-diphenols could be responsible for their antioxidant, anti-inflammatory, and antibacterial properties. To assess antioxidant activity, the scavenging effects of DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,20-Azinobis[3-ethylbenzothiazoline-6-sulfonate]) radicals as well as hydrogen peroxide (H2O2) radicals were used. The antimicrobial activity showed that the black olive extract exhibited the best inhibitory effect, with a minimum inhibitory concentration (MIC) ranging from 0.625 mg/mL to 0.31 mg/mL. The anti-inflammatory activity of tested extracts of black olives of Bejaia (EOBB) and green of olives Mascara (EOGM) was 20.06 µg/mL and 20.21 µg/mL, respectively, which demonstrated the anti-inflammatory effect of these extracts on human beings.

Tuning the chemical functionality of lignocellulosic fiber plays a key role in the development of mechanically strong composites to overcome the lack of compatibility between composite phases, which is a major challenge in multidimensional applications of eco-composites. Herein, coir fiber (CF) surfaces were enriched through four kinds of modification routes – namely, mercerization, amino-functional silane treatment, bio-based epoxy resin sizing and isocyanate treatment – to enhance their interfacial adhesion to a thermoplastic polyurethane (TPU) matrix. The tensile strength and Shore hardness parameters of composites were improved by surface-modified CF inclusions. The thermomechanical response of TPU was optimized after CF loadings regardless of treatment type. The composite with silane-modified CF exhibited the lowest water uptake due to the hydrophobic behavior of the silane layer. The increase in interfacial interaction between the TPU matrix and modified CF was confirmed by scanning electron microscopy investigations. The chemically enriched surface of CF improves the performance of composites, thanks to improved adhesion in the TPU–CF interface.

Published: January 2023

Background: Most common disease of gall bladder and biliary tree is cholelithiasis. Laparoscopic cholecystectomy is now gold standard treatment. Gall bladder contents can be spilled during both in open and laparoscopic cholecystectomy, but these contents are eliminated usually through direct removal, copious irrigation and mopping in open operations. Right shoulder tip pain is a common short term complaint. Aims and objectives were to study right shoulder tip pain, its duration and severity in post-operative period of patients having spillage versus non spillage of gall bladder contents.
Method: It is a hospital based prospective comparative study was conducted in KPC medical college and hospital, Jadavpur, Kolkata. Time frame was April 2021- July 2022. Sample size was 100.
Result: Our study showed that, less number of patients had right shoulder tip pain (in numerical rating scale) and requirement of rescue analgesia in case compared to control group.
Conclusions: Right shoulder-tip pain, which may occur post-laparoscopic cholecystectomy, is variable in duration, severity and character and is more in spillage group.

To compare the fracture resistance of immature teeth subjected to apexification with three different bioactive materials.

Sixty non-carious, single-rooted premolar teeth with straight canals were decoronated at cementoenamel junction, standardizing 13 mm length. After access preparation, the canals were accessed with #10 K-file followed by biomechanical preparation using Ni-Ti ProTaper Gold rotary files upto F3 and irrigation was done using 2 mL 3% NaOCl, 17% EDTA and 5 ml of saline. To simulate immature roots with open apices, #1–5 Peeso reamers were passed through the apex enlarging to 1.5 mm diameter. Later, samples were randomly divided into 4 different groups with 5mm apical plug in each group, Group I: GuttaFlow Bioseal, Group II: Biodentine, Group III: EndoSeal MTA and Group IV: Control group. Samples were filled with an apical plug of 5mm. Later, remaining part of the root canals was obturated with gutta-percha cones and AH Plus sealer by lateral condensation. To stimulate periodontal ligament lining of the root surfaces, C-Silicone light body impression material was used. The samples were stored for 1 week in 100% humidity at 37˚C to ensure that the sealer set in an environment that simulate the clinical situation. Later, fracture resistance was evaluated using the universal testing machine.

Group II (Biodentine) showed highest fracture reisistance followed by Group I (GuttaFlow BioSeal) and Group III (EndoSeal MTA)

Biodentine apexification groups showed highest fracture resistance values followed by GuttaFlow Bioseal and the least values were shown by EndoSeal MTA.

This case report describes the non - surgical management of a large periapical lesion using Metapex as a intracanal dressing and root canal therapy. Periapical lesions usually develop in non-vital teeth as a result of chronic aggression by the pathogenic microorganisms into the root canal which may appear as radiolucent in periapical radiographs. Treatment of such lesions usually varies from non-surgical and surgical means depending on the individual. In the era of minimally invasive, dentistry, non-surgical endodontic approach has been highly recommended in the periapical healing. This case report shows the healing of large periapical lesion using metapex as intracanal medicament at various time intervals followed by root canal therapy.
Incorporating modern caries management into general dental practice: An overview for clinicians in India
Authors: Ghosh Indrajeet , Banerjee Prasanta , Prakash Sugandha
Published: January 2023

The available scientific literature has established the fact that restorations do not last forever. The disease process i.e caries has to be managed as a disease if patients need to heal from it. A caries management plan must be in place for each individual patient for this purpose. The management plan needs to be risk-based and prevention-focused and has to concurrently run during and after the restorative phases of treatment. Only then over treatment in restorative dentistry can be avoided. This paper gives an overview to clinicians in India on modern caries management and how it can be implemented in general dental practice.

Authors: Mishra Shilpa , Patkar Rakesh Rajiv , Neelakantan Amrita
Published: January 2023

Villous adenomas are known to occur in gastrointestinal tract; however, they are very rare in female genital tract. The pathogenesis is unclear but their origin from cloacal remnants has been hypothesized. Here we report a rare incidental case of primary villous adenoma with high grade dysplasia arising from vaginal vault in a 28-year-old female who presented with abnormal vaginal bleeding. The importance of reporting this lies in its pre-malignant behaviour and benign looking clinical appearance.
