Authors: Shi Yongle , Wan Xueli , Li Yaqin , Tian Li
Published: March 2023

Objectives:
To predict the occurrence rates and related factors that can lead to Emergence agitation (EA) among pediatric patients after a cleft lip or palate surgery.
Materials and Methods:
A prospective study was performed to analyze the influencing factors of EA amongst pediatric patients after cleft lip or palate surgeries. The cohort data were collected in the department of oral and maxillofacial surgery of a tertiary stomatological hospital in Chengdu, China, in which patient's demographic variables, monitorization recording of the patient's anesthesia and post-operative situations, and postoperative restlessness assessment records, etc were included.
Results:
One hundred ninety patients who aged from 3 months to 6 years old, underwent cleft lip/palate repair surgeries and were under general anesthesia participated in this study voluntarily. And this process was conducted from June 2020 to October 2020. The univariate analysis showed that the occurrence of EA was affected by weight, age, fasting duration, operation duration, anesthesia duration, usage of iodoform, and level of pain (p < 0.01). Logistic regression showed that age, fasting duration, operation duration, and level of pain influenced the occurrence of EA (p < 0.05).
Conclusions:
Age, operation duration, fasting duration, and level of pain could predict the occurrence of EA among postoperative pediatric patients.
Clinical Relevance:
EA impacts the safety of post-surgery pediatric patients under general anesthesia significantly. Age, operation duration, fasting duration, and level of pain could predict the occurrence of EA among postoperative pediatric patients.

Published: March 2023

Hepatitis B surface antigen (HBsAg) testing is the only method currently used in laboratories to diagnose hepatitis B virus (HBV) infection in febrile patients. The South-South area of Nigeria does not currently have data on the prevalence of anti-HBc-IgM. The main goal of this study was to identify the serological evdience of anti-HBc-IgM markers among febrile patients in Port Harcourt, Nigeria. Following the manufacturer's standard operating procedures, 92 febrile patients were tested for HBc IgM antibody during cross-sectional research from November 2020 to October 2021. The prevalence of anti-HBc IgM antibodies (35.9%) and anti-HBc-IgM negatives was 64.1%. The prevalence of anti-HBc- IgM antibody was higher among older age groups (44.7%), females (53.3%), singles (42.9%), tertiary educational level (42.2%) and civil servants (47.4%). None of the variables evaluated was significantly associated with the prevalence of HBc IgM. This study shows that 35.9% febrile patients have anti-HBcIgM as the only serological evidence of HBV infection. This study identifies a possible danger of HBV transmission from febrile individuals who test positive for anti-HBc to the general population. Anti-HBc-IgM antibodies are prevalent in Port Harcourt among feverish patients. In Nigeria, screening patients who are feverish for anti-HBc IgM should be encouraged. This research represents the first evaluation of anti-HBc IgM in the South-South region of the nation.

Published: March 2023

Mesophilic and thermophilic methanogens belonging to the hydrogenotrophic, methylotrophic, and acetotrophic groups were isolated from Indian hot spring environments using BY and BCYT growth media. Following initial Hinf I based PCR-RFLP screening, 70 methanogens were sequenced to ascertain their identity. These methanogens were phylogenetically and physiologically diverse and represented different taxa distributed across three physiological groups, i.e. hydrogenotrophs (53), methylotrophs (14) and acetotrophs (3). Overall, methanogens representing three families, five genera, and ten species, including two putative novel species, were recognized. The highest number and diversity of methanogens was observed at 40℃, dominated by Methanobacterium (10; 3 species), Methanosarcina (9; 3 species), Methanothermobacter (7; 2 species), Methanomethylovorans (5; 1 species) and Methanoculleus (3; 1 species). Both putative novel methanogen species were isolated at 40℃ and belonged to the genera Methanosarcina and Methanobacterium. At 55℃, limited diversity was observed, and resulted in the isolation of only two genera of methanogens, i.e., Methanothermobacter (28; 2 species) and Methanosarcina (4; 1 species). At 70℃, only members of the genus Methanothermobacter (5; 2 species) were isolated, whereas no methanogen could be cultured at 85℃. Ours is the first study that documents the extensive range of cultivable methanogenic archaea inhabiting hot springs across various geothermal provinces of India.

Land that is displaced due to seawater intrusion is very much found in Indonesia, even in the world, usually rice fields adjacent to ponds. This study aims to try wasteland for the cultivation of rice and tiger shrimp with a brackish water system. The land used belongs to a farmer group that has not been used for the past ten years due to seawater intrusion, located in Oring Hamlet, Lawallu Village, Barru Regency, South Sulawesi Province, Indonesia. Owners leave their lands unproductive, often even diverted to anthropogenic activities. The abandoned land was reconstructed into rice fields for rice crops and trenches for tiger shrimp cultivation. The rice seeds used are saline tolerant, namely the INPARI-34 and INPARI-35 varieties obtained from the Sukamandi Indonesia Rice Seed Center, Ministry of Agriculture. Planted in the rice field after seeding for 25 days. Tiger shrimp post larvae have been adapted for 30 days at a salinity of 7 − 5 ppt (low salinity), with a dense spread of 4 individuals per m2 (traditional plus system). Integrated maintenance of rice and tiger shrimp, following the cultivation procedures, namely, rice weeding, eradication of rice pests and tiger shrimp, and additional fertilization. A sampling of rice and tiger shrimp growth and water quality selection is carried out every 14 days. The results showed that saline-tolerant rice varieties INPARI 34 and INPARI 35 can grow well in saltwater-induced fields with a rice maintenance period of 105 days. Tiger shrimp cultivation integrated with salt-tolerant rice varieties produces a survival value of 20%, and a body weight of 12 grams/individu for 65 days of cultivation.

Published: March 2023

OpenAI's ChatGPT, an advanced AI-driven language model, is experiencing rapid adoption, with 100 million users in just three months. This study, involving 288 university students, aims to identify factors determining students' intentions to use ChatGPT in higher education, using Rogers' perceived theory of attributes as a framework. The study examines five factors influencing ChatGPT adoption: Relative Advantage, Compatibility, Ease of Use, Observability, and Trialability. Results indicate that five factors significantly influenced ChatGPT adoption. Students view it as innovative, compatible, and user-friendly. Students view ChatGPT as an innovative resource, enabling the independent pursuit of educational goals. Consequently, the benefits provided by ChatGPT in education motivate students to utilize the tool. The study's gender-based analysis reveals that male students prioritize compatibility, ease of use, and observability, while female students prefer the ease of use, compatibility, relative advantage, and trialability in ChatGPT adoption. Our study presents a sentiment analysis approach utilizing transfer learning and K-means, considering the impact of personal bias on expressed opinions. While the K-means algorithm can create distinct clusters (Neutral, Negative, and Positive), the accuracy demonstrates a bias towards the male gender. Understanding adopter categories, such as innovators and early adopters, can help strategize the successful diffusion of innovations like ChatGPT to different segments of society. However, its use in academia raises ethical concerns, such as diminished creativity and academic integrity violations. Similar to social media platforms' rapid diffusion, ChatGPT has the potential to transform communication and information-sharing. Factors like ease of use, accessibility, and connection capabilities contribute to both innovations' appeal. Analyzing social media platforms' diffusion can offer insights into ChatGPT's potential adoption trajectory.

Published: March 2023

Background. Diabetes mellitus is a metabolic disorder characterized by hyperglycemia with disturbances of carbohydrate, fat, and protein metabolism, resulting from defects in insulin secretion, insulin action, or both. Managing diabetes mellitus with currently available drugs is costly, and the chances of side effects are high, leading to further studies for new and better medications from plant sources with the affordable and lower side effects. This study aimed to evaluate the antioxidant, antihyperglycemic and, antihyperlipidemic effects of the 80% methanolic extract of Datura stramonium leaves in Streptozotocin-induced diabetic mice.
Methods. Male Swiss albino mice were induced into diabetes using 150mg/kg of STZ. The FBG measurements were done on 0, 7th, and 14th days of treatment. At the end of the experiment, on the 14th day mice were anesthetized with diethyl ether. Then, blood was drawn by cardiac puncture to assess TC, TG, LDL-C, and HDL-C. The antioxidant activity of the extract was determined using a DPPH assay. The data were entered into Epi-Data version 4.6, exported to SPSS version 26.0, and analyzed using a one-way ANOVA followed by a Tukey post hoc test. P < 0.05 was considered statistically significant.
Result. D.stramonium leaves extract showed significant blood-glucose-lowering activity. The extract of D.stramonium reduced the fasting blood glucose level by 19.71%, 30.27%, 40.95%, and 45.67%, respectively, for D. stramonium 100, 200, 400, and GLC 5 mg/kg on the 14th day of treatment. Diabetic mice treated with D.stramonium for 14 days showed a significant decrease in serum TC, LDL, and serum TG and a significant increase in body weight, and HDL level as compared to diabetic negative control. Antioxidant activities of the leaves extract were comparable to ascorbic acid with an IC50 of 172.79 µg/ml.
Conclusion. This study showed that D. stramonium leaves extract possesses significant anti-hyperglycemic, antihyperlipidemic and antioxidant activities.
A closed-form solution for the three-body problem and Sun-Earth-Moon orbit solution
Authors: Abdel-Rahman A. S.
Published: March 2023

The study of the motions of planets, satellites, and other celestial bodies is one of the important problems in basic physics and astronomy. The solution to the two-body problem enables astronomers to predict the orbits of the Moon, satellites, and spaceships around the Earth. The general analytic solution for the three-body problem stands unsolved except in some special cases, such as the Sun-Earth-Moon problem, in which the mass of the Moon is neglected. This reduces the problem to a two-body problem. In this work, the author presents a general solution to the problem in a closed form in terms of two basic particle-particle vectors. The position vector of each particle is expressed in terms of the center of mass and the two basic particle-particle vectors. This solution is used for studying the three-body problem with gravitational interaction without imposing the non-zero-total angular-momentum condition nor ignoring any masses. The Sun-Earth-Moon problem was solved in the general case and showed an expected orbital motion while a perturbation in Earth-Sun orbit due to the revolution of the Moon. This solution is the key for future studies for n-body problem solutions.
Personality traits and psychological self-regulation of students online and offline: To the question of “digital” aspect of socialization

Published: March 2023

Internet activities, especially in adolescents and young people, are related to higher emotions and the wider social roles, comparing to offline. The aim of the study was to reveal manifestations of personality traits and psychological self-regulation online comparing to offline, as well as their relationship with user activity, relationship to Internet and subjective well-being. 260 students filled the Brief Personality Scale, the Balanced Measure of Psychological Needs Scale, and the Cognitive Emotion Regulation Questionnaire, first with original instruction, and then with instruction to assess whether these features are more likely to manifest online or offline. Additional measures included scales of assessment of subjective well-being, user and combined activity, digital competence, attitude to technology, attitude to the digitalization of education. The suggested modifications of the Balanced Measure of Psychological Needs Scale, and the Cognitive Emotion Regulation Questionnaire had sufficient reliability-consistency, which allows use them in research aimed at comparing psychological manifestations online and offline. On the Internet, compared to offline, students were less satisfied with relatedness; they are less self-blaming, accepting, ruminating, focusing on planning, had lower scores on positive reappraisal, perspective taking, and catastrophizing. Higher levels of autonomy, acceptance, rumination, positive refocusing, and perspective taking were related to higher offline rather than online manifestations of these traits. User activity was associated with greater online autonomy, the combined (online and offline) activity — with online competence, and with greater excitability of the digitalization of education with online competence and positive reappraisal. Differences in the manifestations of psychological self-regulation online and offline were not related to subjective well-being. It can be assumed that students’ assessment of their possibilities of psychological self-regulation online, comparing to offline, describes their relationship to their Internet activities and self-image but not general relationship to technologies and digital competence.

In gender studies, there is a lack of instruments to assess the severity of gender inequality in an organization. Gender inequality at the structural level of the organization manifests itself as gender asymmetry in an organization and in certain status positions. It is indicated by metaphors of “glass” phenomena: “glass ceiling”, “sticky floor”, “glass walls”, “glass escalator”, “glass rock”, “glass box”. The article is devoted to the development and testing of the author’s methodology for assessing structural gender barriers in an organization. The study was conducted using an online survey in 2020, with a sample of 273 employees aged 18 to 62 years (median 34 years) from various organizations. The survey included, in addition to the developed questionnaire for assessing structural gender barriers, a methodology for assessing gen- der inequality at the individual-behavioral and normative levels in an organization (“Doing gender” and “Undoing gender” scales, “Scale for the severity of norms that support gender inequality” (author’s development), “Perceptions of Politics Scale” (author’s modification of the methodology of K.Kacmar and D.Carlson). The survey also included questions about the characteristics of the organization to assess the criterion validity. Reliability analysis, correla- tion analysis, and structural modeling were used. The results of the study showed good reli- ability of the scales, the results of SEM analysis show that the obtained data do not correspond to the six-factor model. An exploratory factor analysis was carried out, the resulting one- factor solution explains 54% of the variance. A positive correlation was found between the severity of structural gender barriers and the severity of norms that support gender inequality, with the presence of unfair policies in the organization and with the use of the “Undoing gender” individual behavioral strategy. A negative correlation was obtained with the number of women in high leadership positions in the organization. The obtained results testify in favor of the reliability, constructive and criterion validity of the new instrument. It is planned to further test the properties of the questionnaire on a larger sample.

Published: March 2023

La Evaluación de Carácter Diagnóstico Formativo (ECDF) es conocida por ser decisoria para el ascenso y la reubicación salarial de los docentes del sector público regidos por el decreto 1278 de 2002, y tiene como propósito la realización de un diagnóstico formativo que permita la reflexión y el monitoreo del desempeño por parte de las instituciones y de los maestros involucrados. El presente escrito busca caracterizar y analizar la ECDF, dando cuenta de la brecha entre las intenciones de la normativa y los efectos prácticos de la evaluación, así como presentar las experiencias de algunos de los docentes que han participado de ella. Se propone una aproximación a través del estudio de las normativas y otros documentos técnicos por los cuales se reglamentó, diseñó y desarrolló la prueba, así como la realización de entrevistas para conocer la experiencia de los y las docentes frente a la misma. Se identifica que el objetivo de la prueba no es alcanzado satisfactoriamente, en tanto la aplicación y su posterior retroalimentación ha sido deficiente, al no brindar a los y las docentes información clara y pertinente sobre sus prácticas pedagógicas que garantice un aporte a la transformación de su labor.
Gobernanza y calidad educativa en Colombia: reflexiones desde la nueva economía institucional
Authors: Ariza Dau Marco , Ramos Ruiz José Luis , Rosado Salgado Luis
Published: March 2023

Este artículo presenta una reflexión sobre el potencial de contribución de la Nueva Economía Institucional para abordar el estudio de los sistemas educativos y su desempeño. Además de analizar los elementos teóricos de este enfoque aplicados al sistema educativo y revisar los aportes empíricos recientes desde la literatura; se analiza la problemática específica en Colombia para llegar a una propuesta de estudio que involucre estos elementos teóricos soportados en supuestos más realistas. Se cuestiona el uso de la lógica neoclásica para explicar el desempeño y las limitaciones desde la teoría de la agencia, abriendo paso al enfoque de gobernanza como alternativa de estudio acorde con la naturaleza de los procesos de organización y gestión de los sistemas educativos, especialmente en el sector público. Se concluye a favor del potencial de las instituciones y del enfoque contractual para abordar el estudio de los sistemas educativos, a pesar de los posibles problemas de medición que se puedan enfrentar. Así, las diversas formas de organización de la educación en el sector público y su naturaleza jerárquica y el análisis de los costos de transacción cobran importancia más allá del análisis ortodoxo de los costos de producción.
Literature Review of Public Administration and Good Governance from 1890 to 2023
Authors:   Cape Peninsula University of Technology, South Africa., Barbier Lance , K Tengeh Robertson
Published: March 2023

This article examines public administration from 1890 to 2023 to see how it evolved and influenced practice and if good governance is a crucial component in this transformation. This paper presents an in-depth review of several different pieces of secondary literature sources. This paper produced several key findings. The most important finding of this literature study is that, between 1890 and 1980, the Public Administration transitioned from "Traditional Public Administration" to "New Public Management" due to the growing need for good governance. The year 2000 saw the birth of a novel idea in public administration known as "New Public Governance," which has persisted in practice ever since. This paper will be useful to Public Administration practitioners worldwide. There has been little empirical research into how the evolution of Public Administration encourages governments to act more like private corporations. Consequently, more research on this subject is encouraged.

Practices on the outcomes-based education (OBE) implementation in select HEI graduate school programs in the Philippines as input to institutionalizing mandatory accreditation
Authors:   College of Education, Northern Iloilo State University, Batad, Iloilo, Philippines, Hapinat Hene L.
Published: March 2023

This qualitative-quantitative research aimed to determine the extent of practices in the implementation of Outcomes-Based Education (OBE) among select Higher Education Institutions (HEIs) in Panay Island, Philippines in terms of an academic institution’s Vision-Mission-Goals, faculty, curriculum and instruction, support to students, research, extension and community involvement, library, physical facilities, laboratories, and administration. Further, this study aimed to find whether the practices of the respondents on OBE implementation are influenced by the level of accreditation. The respondents of the study were the 120 permanent faculty members coming from 17 HEIs offering graduate school programs. The data gathered would provide the basis for institutionalizing mandatory accreditation among HEIs. Using the Accreditation Survey Instrument (ASI) of the Accrediting Agency of Chartered Colleges and Universities in the Philippines (AACCUP), the results revealed that the extent of practices on the OBE implementation except in areas of research, and extension and community involvement were very satisfactory. The result is attributed to the fact that HEIs have met 50% greater than the standards, demonstrating good OBE practices in their graduate school programs. Furthermore, the results of the study also show that the challenges encountered by the faculty members in the practices of OBE implementation were evident in poor research outputs due to inadequate research and extension funds, resulting in weak extension, community involvement, and poor linkages. The level of accreditation of HEIs has a direct bearing and significant influence on the extent of their practices on OBE implementation. Therefore, accreditation is a practical scheme to evaluate and monitor quality program offerings among HEIs in the Philippines to maintain higher standards through OBE typology.

Potential Impact of the COVID-19 Pandemic on Public Perception of Water Pipes on Reddit: Observational Study
Authors: Zheng Zihe , Xie Zidian , Goniewicz Maciej , Rahman Irfan , Li Dongmei
Published: March 2023

Background

Socializing is one of the main motivations for water pipe smoking. Restrictions on social gatherings during the COVID-19 pandemic might have influenced water pipe smokers’ behaviors. As one of the most popular social media platforms, Reddit has been used to study public opinions and user experiences.

Objective

In this study, we aimed to examine the influence of the COVID-19 pandemic on public perception and discussion of water pipe tobacco smoking using Reddit data.

Methods

We collected Reddit posts between December 1, 2018, and June 30, 2021, from a Reddit archive (PushShift) using keywords such as “waterpipe,” “hookah,” and “shisha.” We examined the temporal trend in Reddit posts mentioning water pipes and different locations (such as homes and lounges or bars). The temporal trend was further tested using interrupted time series analysis. Sentiment analysis was performed to study the change in sentiment of water pipe–related posts before and during the pandemic. Topic modeling using latent Dirichlet allocation (LDA) was used to examine major topics discussed in water pipe–related posts before and during the pandemic.

Results

A total of 45,765 nonpromotion water pipe–related Reddit posts were collected and used for data analysis. We found that the weekly number of Reddit posts mentioning water pipes significantly increased at the beginning of the COVID-19 pandemic (P<.001), and gradually decreased afterward (P<.001). In contrast, Reddit posts mentioning water pipes and lounges or bars showed an opposite trend. Compared to the period before the COVID-19 pandemic, the average number of Reddit posts mentioning lounges or bars was lower at the beginning of the pandemic but gradually increased afterward, while the average number of Reddit posts mentioning the word “home” remained similar during the COVID-19 pandemic (P=.29). While water pipe–related posts with a positive sentiment were dominant (12,526/21,182, 59.14% before the pandemic; 14,686/24,583, 59.74% after the pandemic), there was no change in the proportion of water pipe–related posts with different sentiments before and during the pandemic (P=.19, P=.26, and P=.65 for positive, negative, and neutral posts, respectively). Most topics related to water pipes on Reddit were similar before and during the pandemic. There were more discussions about the opening and closing of hookah lounges or bars during the pandemic.

Conclusions

This study provides a first evaluation of the possible impact of the COVID-19 pandemic on public perceptions of and discussions about water pipes on Reddit.
Data Provenance in Biomedical Research: Scoping Review (Preprint)
Authors: Johns Marco , Meurers Thierry , Wirth Felix N , Haber Anna C , Müller Armin , Halilovic Mehmed , Balzer Felix , Prasser Fabian
Published: March 2023

BACKGROUND

Data provenance refers to the origin, processing, and movement of data. Reliable and precise knowledge about data provenance has great potential to improve reproducibility as well as quality in biomedical research and, therefore, to foster good scientific practice. However, despite the increasing interest on data provenance technologies in the literature and their implementation in other disciplines, these technologies have not yet been widely adopted in biomedical research.

OBJECTIVE

The aim of this scoping review was to provide a structured overview of the body of knowledge on provenance methods in biomedical research by systematizing articles covering data provenance technologies developed for or used in this application area; describing and comparing the functionalities as well as the design of the provenance technologies used; and identifying gaps in the literature, which could provide opportunities for future research on technologies that could receive more widespread adoption.

METHODS

Following a methodological framework for scoping studies and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines, articles were identified by searching the PubMed, IEEE Xplore, and Web of Science databases and subsequently screened for eligibility. We included original articles covering software-based provenance management for scientific research published between 2010 and 2021. A set of data items was defined along the following five axes: publication metadata, application scope, provenance aspects covered, data representation, and functionalities. The data items were extracted from the articles, stored in a charting spreadsheet, and summarized in tables and figures.

RESULTS

We identified 44 original articles published between 2010 and 2021. We found that the solutions described were heterogeneous along all axes. We also identified relationships among motivations for the use of provenance information, feature sets (capture, storage, retrieval, visualization, and analysis), and implementation details such as the data models and technologies used. The important gap that we identified is that only a few publications address the analysis of provenance data or use established provenance standards, such as PROV.

CONCLUSIONS

The heterogeneity of provenance methods, models, and implementations found in the literature points to the lack of a unified understanding of provenance concepts for biomedical data. Providing a common framework, a biomedical reference, and benchmarking data sets could foster the development of more comprehensive provenance solutions.

In the current study, we investigated the fertility desire of PLHIV in China and other regions and further explored the possible influence factors, aiming to provide better guidance for formulating relevant policies.
PubMed, PsycINFO, Cochran library, EMBASE, Google academy, China National Knowledge Infrastructure (CNKI), China biomedical literature database and Wan fang Database were subjected to search for potentially relevant articles published before February 2023. NoteExpress software was used to summarize and encode the data, and double entry was used to enter the data. According to the fertility intention, the samples were divided into fertility intention group and non-fertility intention group, using Review Manager 5.2 statistical software for meta-analysis.
A total of 15 articles with 7578 subjects were included. Four relatively strong correlation factors named education level, martial status, age and number of children were defined and analyzed. The results showed that PLHIV who were highly educated, married, younger than 30 years old or without children exhibited stronger fertility desire whether in China or other regions, followed by the pooled odds: education level (ORchina=1.27, 95%CI: 0.98-1.64; ORothers=1.32, 95%CI: 1.11-1.56), martial status (ORchina=1.32, 95%CI: 1.01-1.73; ORothers=1.70, 95%CI: 1.46-1.97), age (ORchina=4.02, 95%CI: 2.97-5.43; ORothers=2.89, 95%CI: 2.38-3.49), number of children (ORchina=5.52, 95%CI: 4.18-7.30; ORothers=1.67, 95%CI: 1.42-1.97). The pooled prevalence of fertility desire of participants without children in China (64.4%; 95%CI: 31.7%, 97%) was higher than the prevalence in other regions (58.8%; 95%CI: 44.8%, 72.8%), while the prevalence of other groups in China were all lower than those in other regions.
There was a significantly higher prevalence and odds of fertility desire in those who are highly educated, under the age of 30, no children and married. Additionally, the group without children in China had a higher prevalence of fertility desire than in other regions.

Mining has played a significant role in the development of a country. The financial progress of various nations depends on the production and use of minerals which leads to the expansion of mining activities. Ballari district has rich mineral resources and is known for iron ore deposits. As iron ore is an essential raw material for the iron and steel industry, many Iron and Steel plants are established in Ballari district. In this study, the impacts of iron ore mining on environmental issues such as air, water, soil, and health on the population are reviewed. The review reports that the concentrations of NO2, SO2, PM10 and PM2.5 are greater in the core zone of Subbarayanahalli iron ore mine located in Hospet-Ballari sector. The PM10 level exceeds the NAAQS limits of 100 µg/m3 at different locations of 10kms radius of Ballari city. The surface water bodies around Sandur, Torangallu and Taranagar are silted and contaminated by mining waste. The airborne dust produced during mining activities decreased crop productivity and affected human health. The main conclusion from the review is that more research should be needed to assess the environmental impacts and emphasize sustainable mining operations in association with Government and mining research activities.

Published: March 2023

Feedback of 250 Livestock Development Officers (LDO) of Maharashtra state was taken regarding the livestock health care delivery system in pre constructed format. The study revealed that 17.60 % LDO were looking after five and more than five dispensaries and23.20 % LDO were taking care of livestock from more than 20 villages. Many of the LDOs (56.80 %) were also involved in different extension works such as implementation of Gov. Schemes, survey work and cattle show etc., besides treatment of animals. Majority of the officers (72.40 %) visited farmer’s house as and when farmers called. Moreover, 69.60 % LDO informed that they visited village for the treatment of livestock very often.Most of the officers informed about sufficient stock of vaccine (82.00 %), antibiotic (60.00 %), anthelmentis and analgesics (63.60 %), but 42.00 % LDO reported scarcity of vitamin and mineral mixture.In respect of disease outbreak / occurrence, LDO reported outbreak of 22 diseases in livestock and poultry. Most occurrence of disease was FMD in cattle (28.00 %), followed by PPR in goat (24.80 %) and HS in cattle (14.40%). 31.20 % respondents reported more than two weeks time was needed to get diagnostic report of disease from the testing laboratory.32.80 % LDO informed that they reported to the District Animal Husbandry Officer regarding outbreak / occurrence of disease.The officers revealed that the regular vaccination was carried out against FMD (97.20 %),HS (93.20 %) and BQ (92.00 %). 35.60 % respondents reported vaccine failure and cause of vaccine failure was found to be improper storage and transportation of vaccine (17.20 %) followed by untimely vaccination (10.80 %) and some even doubted about the quality of vaccine. 47.60 % LDO reported the sufficient availability of acaricide and 67.20 % respondents informed sufficient availability of anthelmintic in the animal health center.Artificial Insemination was preferred over natural service by farmers for breeding of livestock as reported by 83.60 % respondents.Conception rate in AI was reported to be 45.27 %, whereas number of AI / conception was reported to be 2.85. Reason for preference of AI by most of the farmers was easy availability (46.00 %) followed by better conception rate (43.60%).
Globalizing financial valuation: International property consultants in São Paulo
Authors: Shimbo Lucia , Sanfelici Daniel
Published: March 2023

International property consultants (IPCs) have become key intermediaries in the globalization of property markets by providing a range of services that generate transparency and comparability in land and property-based investments. While their role in generating standardized information on local markets is well known, what is less is known is how IPCs help turn property into an income-yielding asset in less developed economies. This article investigates the contested diffusion of financialized valuation approaches in São Paulo's local property market. Through a qualitative inquiry into large IPCs and their main clients in the city, we show that IPCs have promoted valuation approaches that are tailored to the needs of financial market investors, thus affecting key investment decisions taken by diverse actors. Though these financialized techniques have at times clashed with more traditional views of property ownership prevalent in the country, we show that most often they co-exist with long-established valuation techniques that reflect the social and economic circumstances of Brazil's economy. The socially contingent nature of property valuation raises theoretical issues concerning the complexity of attributing value to fixed capital, as well as several policy issues.
Financial delusions and the persistence of capital
Authors: Vighi Fabio
Published: March 2023

The dominant view among critics of today's debt-based and increasingly volatile economy is that, at some point in the seventies or eighties, capitalism took the wrong turn, falling victim to greed and corruption. This view, a familiar narrative in a world that loves to personalise guilt, is flawed. It assumes that our finance-driven system is the fraudulent version of a fundamentally rational mode of production. As I have argued in a recent book, capitalist society is no longer able to reproduce itself through the value extracted from labour (Vighi, 2022). Increasingly and overtly, capitalism is driven by leveraged, speculative returns on financial assets. While it is delusional to believe that value can be produced through securitisation ad infinitum, to imagine that we should look to a putative ‘real economy’ to ignite a new growth cycle only means we are willing to be fooled twice. The financial demon is nothing but an expression of the inner demons of capitalism as such.

Published: March 2023

A graph topology defined on a graph G is a collection 𝒯 of subgraphs of G which satisfies the properties such as K0, G ∈ 𝒯 and 𝒯 is closed under arbitrary union and finite intersection. Let (X, T) be a topological space and Y ⊆ X then, TY = {U ∩ Y : U ∈ T} is a topological space called a subspace topology or relative topology defined by T on Y. In this P1 we discusses the subspace or the relative graph topology defined by the graph topology 𝒯 on a subgraph H of G. We also study the properties of subspace graph topologies, open graphs, d-closed graphs and nbd-closed graphs of subspace graph topologies.

Abstract: In developing nations, with the raising overpopulation, both economy and pollution free environment in construction industry are of principal importance in order to meet the undeniable human needs of multifarious forms. Thus, use of waste aggregates in the manufacturing is of new type of concrete, which plays a critical role in the construction industry, for fulfilling the demand of aggregates. Most of the waste materials are arising from industrial waste and demolishing waste. Hence, recycling, reuse and exchange of this waste appears to be an effective solution and most appropriate decision. In the current research work desirable characteristics of recycled aggregate concrete were considered. These experiments were conducted for different ages of concrete such as 7 and 28 days to assess the split tensile strength. The workability properties of mix are evaluated by workability tests are flow test. It addresses experiment on different mixes of self- compacting concrete. One with fresh coarse and fine aggregates, while the others with restoration of 15%, 30%, 45%, 60%, 75%, 90% and 100% recycled fine aggregates. The design mix proportion in M25 with the proportionate of 1:1:2 for self-compacting concrete is taken.

Abstract: The purpose of this study was to control the factors that are responsible for plants growth in hydroponics systems and automate them to reduce the human effort with less space and electricity. In this paper we used a combination of two methods: Deep water culture and Nutrient film technique for the system. In this method plants will have continuous nutrient supply. We used a linear regression method to control EC and pH of the system and the microcontroller will send signals to the system to adjust them to desired value with the help of dozers by taking average EC and pH values.
Online Voting System Using Face Recognition and OTP(One-Time Password)
Authors: Roy Arnab
Published: March 2023

Abstract: The fundamental idea behind this system is to provide an online voting system that will aid in reducing fraud in manual voting systems and earlier iterations of online voting that used a webcam for face recognition and OTP generating. Also, we are introducing a location-free voting mechanism for voters who are unable to visit the polling location (hometown). Here, we suggest a method that uses various layers of authentication, starting with face recognition and continuing with OTP verification using validation data, to guarantee the device's dependability. Only after being identified and verified against the provided database of registered voters may each voter access the system. When the information provided and the corresponding face match, the voter will be permitted to move through with selecting their top candidate from the panel.
