In developing countries, nitrogen in the traditional market wastewater is a critical environmental problem. In this study, the microalga Chlorella sp., which was isolated from wastewater, was used to remove the total nitrogen (TN) from conventional market wastewater in combination with audible sound (Vietnamese classical music). In addition, effects of sound exposure on removal efficiency at different initial cell densities were analyzed. Results revealed that music sound control demonstrates potential to improve the removal efficiency. TN removal efficiencies of 96%, 69.5%, and 4.3% were observed for treatments with Chlorella sp./audible sound, Chlorella sp., and without Chlorella sp., respectively. The significance of probability value (p-value) (<0.05) on the paired sample t-test confirmed the critical role of audible sound and Chlorella sp. density on the TN removal in screening experiments. The predicted optimal conditions for TN removal were as follows: a Chlorella sp. density of 4%, an audible sound of 52.5 dB, and a cultivation time of 4.6 days. Results based on statistical analysis revealed that the quadratic models for TN removal are significant at a low p-value (<0.05) and a high predicted coefficient of determination (R2 = 0.9452) value. The obtained statistical results also indicated that most of the variables are significant for the abatement of TN from market wastewater using Chlorella sp.
Adsorption modeling of organic compounds (OCs) by carbon nanotubes (CNTs): role of OC and CNT properties on the linear solvation energy relationship
Authors: Ersan Gamze
Published: August 2021

This study evaluated a comprehensive database for the adsorption of polar and nonpolar organic compounds (OCs) by carbon nanotubes (CNTs) and to use the linear solvation energy relationship (LSER) technique for developing predictive adsorption models of OCs by multi-walled carbon nanotubes (MWCNTs) and single-walled carbon nanotubes (SWCNTs). The results showed that coefficient of determinations (R2) values for all compounds are higher variability in the 200 g/mol molecular weight cutoff (74–99%). When the molecular weight cutoff of all OCs is higher than 200 g/mol, the trend of their R2 values is decreased (less than 70%). Among all adsorbate descriptor coefficients, V and B terms are the most significant descriptors (p-values ≤ 0.05) in LSER equations for adsorption of low molecular weight polar and nonpolar OCs by both CNTs. Besides, KOW normalization of all Kd values did not have significant impact on the regression of the LSER model, indicating that hydrophobic interactions are not sole mechanism for the adsorption of OCs on CNTs. Lastly, SWCNTs exhibited higher polar OCs uptake than MWCNTs, which was attributed to more polar surface of SWCNTs as suggested by its high oxygen content (%10).
The economic and foundation activity of Jan of Pilcza (ca. 1405-1476), the Castellan of Cracow. The profile against the background of the selected Iuniores faction representatives’ activity
Authors: Szyrwiński Jan
Published: August 2021

The article presents the most important examples of castellan Jan from Pilcza economic and foundational activity in the context of other Iuniores faction members achievements. The text elaborates endowments and ways of managing the lands by Jan from Pilcza and members of the young nobles party. It contains also some observations about common points of iuniores actions – groups known as the main part of the opposition against bishop Zbigniew Oleśnicki. Recognition of these activities profiles is helpful in better understanding the ideological and political attitude of medieval Crown of Polish Kingdom noble elite representatives, who were participants of Spytko from Melsztyn confederetion. The Jan from Pilcza biography is an example of political and social advancement in times of Władysław III and Kazimierz Jagiellończyk reigns. His economic activity had been mainly based on profits from his lands and developing, inter alias, trade markets. Privileges which he dedicated for Tyczyn and Łańcut confirm the observed trend. Also mining was an economy branch developed in described region by Jan from Pilcza. The mentioned activity had a positive impact on defensive capability of Crown of Polish Kingdom. Jan from Pilcza’s economic activities, such as salt-mining organizing, could be viewed as similar to other iuniores. In that context it is necessary to highlight that iuniores chantry actions, endowments and a lot of connections between them and catholic Church are denying the thesis about Hussitism among this political faction representatives.

The kept collection of incunabula is not uniform in terms of their origins. Although this is a small collection, in many ways it is interesting concerning both authors, areas of their knowledge, notes of origin or their binding. The library has in total twelve bibliographical positions in ten volumes. They are the work of workshops located in four urban centres: Venice, Cologne, Strasbourg and Augsburg. All of the collection of books are concentrated around four major groups: Scripture, Theology, law and philosophy. The authors of those works were the most prominent representatives of medieval science. Part of the incunabula’s cover are from the period of the book’s print (turn of fifteenth and sixteenth century), part of them are from the later period.
Theory and practice. Verifying the command skills of the graduates of Polish Military School in Genoa and Cuneo (1861-1862) during the January Uprising (1863-1864)
Authors: Buława Adam

In the run-up to independence uprising, from October 1861 to June 1862 thanks to permit the authorities of the United Kingdom of Italy and the intervention of Giuseppe Garibaldi functioned in Genoa and Cuneo Polish Military School was closed due to diplomatic pressure by the partitioning powers. Over the course of several months was the theoretical preparation of the January Uprising leadership cadre, and 15 graduates covered the self-command of the guerrilla armed parties. 4 of them belonged to the most prominent commanders for the entire war, also 4 can be regarded as promising. One showed just to be average, two were clearly weak. In two cases, it is difficult to set a clear assessment. For two commanders, former soldiers of the Austrian army were disappointing in the field. The Italic episode was an added element of military knowledge. The most significant was the individual’s charac-teristics, although it certainly proved to be a useful body of knowledge transmitted by the emigration of well-prepared teachers cadet school.
Artistic genesis of the mausoleum of Józef Fraget at old Powązki cemetery in Warsaw
Authors: Wiraszka Marta
Published: August 2021

Neoclassical mausoleum of Józef Fraget (1797-1867) commemorating a French industrial entrepreneur and the founder of the first factory of clad goods in Poland was constructed at Old Powązki Cemetery in Warsaw between 1867 and 1869 (quarter A, row I). The author of the torso is Leonard Marconi, and the mold is believed to have been made by the “Lilpop, Rau i Loewenstein” factory in Warsaw. The original project embraced only the top, cast iron part of the tomb in the form of Doric aedicule with entablature and triangular pediment as well as the marble torso placed on prism pedestal located among four columns. The bottom, stone part, was executed later, approximately in 1913 in Władysław Tuszyński stone enterprise.

The Mausoleum of Fraget is a replica of the monument situated in Berlin at St. Dorothy’s Cemetery commemorating Johann August Borsig (1804-1854), the owner of the well-established metal factory in Europe. Its designer was an architect from Berlin, an apprentice of Schinkl, Johann Heinrich Strack, and the maker of the bronze torso mold was asculptor Christian Daniel Rauch. Three other mausoleums originated from the same model: the Brand family mausoleum at the Metallurgical Cemetery in Gliwice, (between 1865 and 1890), Tomas Evans mausoleum at the Evangelical Reformed Cemetery in Warsaw (second half of the 60s. the XIX century, currently non-existent) and in its slightly modified form, the tomb of the architect J. H. Strack at the St Dorothy’s Cemetery in Berlin (1880-1882).

All the above -mentioned mausoleums except the monument decorating the tomb of the architect Strack, commemorated personalities from metallurgical industry. The particularity of the mausoleum of Józef Fraget consists in the use of cast iron as the main constructing element. It is a distinctive feature differing the mausoleum in question from the remaining exemplary monuments made of stone.
"The Hungarian track”. From the Spring of Nations (1848-1849) in the territory of the Crown of Saint Stephen to the Polish Uprisings (1863-1864), Vol. I
Authors: Buława Adam
Published: August 2021

During the Spring of Nations in the lands of the Crown of St. Stephen (1848-1849), traditional ties of friendship, with the possibility of a military confrontation occurring with one, two invaders attracted a large crowd of Polish volunteers for the formation of the Hungarian honveds. About 4,000 Poles were fighting directly in the ranks of the revolutionary army, and enrolled to the national legions under the command of Generals Joseph Wysocki alongside the Transylvanian Army Fieldmarshal Joseph Bem. Among them, about 20 individuals who will be later on commanders of the guerrilla armed troops of the January Uprising (1863-1864). For this reason, it is worth recalling the experience that the military group acquired during the battles for the Hungarian Plain, Slovakia, Bukovina, Moldavia, Banat, Backa and Transylvania.

Predicting Chromosome Flexibility from the Genomic Sequence Based on Deep Learning Neural Networks
Authors: Peng Jinghao , Peng Jiajie , Piao Haiyin , Luo Zhang , Xia Kelin , Shang Xuequn
Published: August 2021

Background:

The open and accessible regions of the chromosome are more likely to be
bound by transcription factors which are important for nuclear processes and biological functions. Studying
the change of chromosome flexibility can help to discover and analyze disease markers and improve
the efficiency of clinical diagnosis. Current methods for predicting chromosome flexibility based
on Hi-C data include the Flexibility-Rigidity Index (FRI) and the Gaussian Network Model (GNM), which
have been proposed to characterize chromosome flexibility. However, these methods require the chromosome
structure data based on 3D biological experiments, which is time-consuming and expensive.

Objective:

Generally, the folding and curling of the double helix sequence of DNA have a great impact
on chromosome flexibility and function. Motivated by the success of genomic sequence analysis in biomolecular
function analysis, we hope to propose a method to predict chromosome flexibility only
based on genomic sequence data.

Methods:

We propose a new method (named "DeepCFP") using deep learning models to predict chromosome
flexibility based on only genomic sequence features. The model has been tested in the
GM12878 cell line.

Results:

The maximum accuracy of our model has reached 91%. The performance of DeepCFP is close
to FRI and GNM.

Conclusion:

The DeepCFP can achieve high performance only based on genomic sequence.

Authors: Davidescu Eugenia Irene , Odajiu Irina , Sandu Constantin-Dragoș , Ghergu Amalia , Luca Dimela , Mureșanu Dafin Fior , Popescu Bogdan Ovidiu
Published: August 2021

Background:

Natalizumab is a humanized monoclonal antibody with high efficacy and
an acceptable safety profile used in the treatment of patients with multiple sclerosis (MS).

Objectives:

Our aim was to report data regarding long-term administration of Natalizumab in patients
with Relapsing-Remitting Multiple Sclerosis (RRMS) from our clinic.

Methods:

A retrospective observational study was performed including RRMS patients who underwent
treatment with ≥ 24 Natalizumab infusions. We analyzed EDSS values, the relapse rate and
the rate and type of adverse events related to Natalizumab administration.

Results:

51 subjects were included with a predominance of women (62.74%), with an average age
of 40.43±1.49 years, a mean disease duration of 9.86±0.7 years and mean number of Natalizumab
infusions of 45.58±2.74. An increased number of patients (80.39%) were relapse-free and a mild reduction
of the mean EDSS value following Natalizumab initiation in patients who had not been
treated with other disease modifying therapies anteriorly was observed. Among the encountered adverse
events such as increased liver transaminases (13.72%), local infections (7.84%) and dysmenorrhea
in one patient were registered in this study. The rate of severe adverse events was 3.92 and
no cases of Progressive Multifocal Leukoencephalopathy (PML) were registered.

Conclusions:

Natalizumab proves to be effective, has an adequate safety profile and can be administered
with good tolerability for a rather extended period of time, provided that the patients are closely
monitored.

Digital Technology Tools to Examine Patient Adherence to a Prescription-Only Omega-3 Polyunsaturated Fatty Acid Therapy To Mitigate Cardiovascular Risk: Protocol for a Prospective Observational Study and Preliminary Demographic Analysis (Preprint)
Authors: Arutyunov Gregory P , Arutyunov Alexander G , Ageev Fail T , Fofanova Tatiana V
Published: August 2021

BACKGROUND

Sustained adherence and persistence with prescription medications is considered essential to achieve maximal treatment benefit for patients with major chronic, noncommunicable diseases such as hyperlipidemia and lipid-associated cardiovascular disease. It is widely documented, however, that many patients with these conditions have poor long-term adherence to their treatments. The population of Russia is affected by poor adherence in the same ways as populations elsewhere and continues to have high rates of cardiovascular disease.

OBJECTIVE

The purpose of this study was to examine patient adherence to a prescription-only preparation of highly purified omega-3 polyunsaturated fatty acids (1.2 to 1 eicosapentaenoic acid to docosahexaenoic ratio, 90% purity) in a large sample of patients at risk for cardiovascular diseases using digital technology to monitor patient behavior and as an outreach facility for patient education and engagement.

METHODS

We conducted a 6-month prospective observational study (DIAPAsOn) at >100 centers in the Russian Federation. A bespoke electronic data capture and patient engagement system were developed with a well-established Russian technology supplier that enables information obtained during clinic visits to be supplemented by remote patient self-reporting. Other aspects of the program included raising patients' awareness about their condition via educational materials available in personal patient accounts in the electronic system.

RESULTS

From an initial cohort of 3000 patients, a safety population of 2572 patients (age: mean 60 years) with an equal proportion of men and women has been characterized. There was widespread concomitant cardiovascular pathology and commensurate use of multiple classes of cardiovascular medication, notably lipid-modifying and antihypertensive drugs. The program was completed by 1975 patients, of whom 780 were prescribed highly purified omega-3 polyunsaturated fatty acid supplements for secondary prevention after myocardial infarction and 1195 were prescribed highly purified omega-3 polyunsaturated fatty acid supplements for hypertriglyceridemia. Data collection and analysis have been completed.

CONCLUSIONS

DIAPAsOn will provide insights into patient adherence with prescription-grade omega-3 polyunsaturated fatty acid therapy and perspectives on the role of mobile technology in monitoring and encouraging adherence to therapy.

Gamification and Game-Based Strategies for Dermatology Education: Narrative Review (Preprint)
Authors: Szeto Mindy D , Strock Daniel , Anderson Jarett , Sivesind Torunn E , Vorwald Victoria M , Rietcheck Hope R , Weintraub Gil S , Dellavalle Robert P
Published: August 2021

BACKGROUND

Game-based approaches, or gamification, are popular learning strategies in medical education for health care providers and patients alike. Gamification has taken the form of serious educational games and simulations to enable learners to rehearse skills and knowledge in a safe environment. Dermatology learners in particular may benefit from gamification methods, given the visual and procedural nature of the field.

OBJECTIVE

This narrative review surveys current applications of gamification within general medical training, in the education of dermatology students, and in dermatology patient outreach.

METHODS

A literature search was performed using PubMed, Google Scholar, and ResearchGate to access and review relevant medical education- and dermatology-related gamification studies published in peer-reviewed journals. Two independent researchers with education and experience in dermatology screened publications to select studies featuring a diversity of gamification approaches and study subjects for in-depth examination.

RESULTS

A total of 6 general medical education–related and 7 dermatology-specific gamification studies were selected. Gamification generally increased motivation and engagement, improved reinforcement of learning objectives, and contributed to more enjoyable and positive educational experiences compared to traditional modes of instruction. Enhancing examination scores, building confidence, and developing stronger team dynamics were additional benefits for medical trainees. Despite the abundance of gamification studies in general medical education, comparatively few instances were specific to dermatology learning, although large organizations such as the American Academy of Dermatology have begun to implement these strategies nationally. Gamification may also a provide promising alternative means of diversifying patient education and outreach methods, especially for self-identification of malignant melanoma.

CONCLUSIONS

Serious games and simulations in general medical education have successfully increased learner motivation, enjoyment, and performance. In limited preliminary studies, gamified approaches to dermatology-specific medical education enhanced diagnostic accuracy and interest in the field. Game-based interventions in patient-focused educational pilot studies surrounding melanoma detection demonstrated similar efficacy and knowledge benefits. However, small study participant numbers and large variability in outcome measures may indicate decreased generalizability of findings regarding the current impact of gamification approaches, and further investigation in this area is warranted. Additionally, some relevant studies may have been omitted by the simplified literature search strategy of this narrative review. This could be expanded upon in a secondary systematic review of gamified educational platforms.
Acceptability, Engagement, and Exploratory Outcomes of an Emotional Well-being App: Mixed Methods Preliminary Evaluation and Descriptive Analysis (Preprint)
Authors: Eisenstadt Amelia , Liverpool Shaun , Metaxa Athina-Marina , Ciuvat Roberta Maria , Carlsson Courtney
Published: August 2021

BACKGROUND

There is growing evidence suggesting that the emotional well-being of the public has been negatively affected in the past year. Consequently, demand for well-being support has increased. Although there is substantial empirical support for mental health apps that target diagnosed conditions, there is less research on emotional well-being apps. Among existing well-being apps, few studies have been conducted on apps that are based on lived experience and those that seek to enhance users’ understanding of their emotional patterns. Thus, the acceptability of these novel apps requires further evaluation before upscaling.

OBJECTIVE

This evaluation aims to describe the acceptability, engagement, and preliminary outcomes of using an app (Paradym) designed to promote emotional well-being and positive mental health.

METHODS

This is a pre-post, mixed-methods, single-arm evaluation that is aggregated with digital analytics data. We anonymously collected real-world data on the demographics and well-being of the participants as well as the usability and acceptance of the app using validated questionnaires and open-ended questions. Participants tested the app for a minimum of 2 weeks before completing the follow-up measures. Google Analytics was used to record the level of app engagement. Chi-square and 2-tailed t tests were conducted to analyze quantitative data, and a thematic analysis approach was adopted for qualitative data.

RESULTS

A total of 115 participants completed baseline questionnaires, of which 79.1% (91/115) users downloaded the app. The sample was diverse in terms of ethnicity, including 43.4% (50/115) people who self-identified as belonging to minority ethnic groups. Most of the participants were female (78/115, 67.8%) and between the ages of 18 and 25 years (39/115, 33.9%). A total of 34 app users who completed questionnaires at baseline and follow-up provided valuable feedback to inform the future directions of Paradym. Favorable themes emerged describing the app’s content, functionality, and underlying principles. Although usability feedback varied across items, a considerable number of participants (22/34, 64%) found that the app was easy to use. Google Analytics revealed that at least 79% (27/34) of people used the app daily. On the basis of preliminary observations, app users experience increased mental well-being. Post hoc analyses indicated that the reduction in depression scores (t33=−2.16) and the increase in the well-being measures (t33=2.87) were statistically significant. No adverse events were reported during the follow-up period.

CONCLUSIONS

The findings of this evaluation are encouraging and document positive preliminary evidence for the Paradym app.

Representation of Personal and Person-Generated Data with HL7 FHIR and HAPI Endpoint Security with TSD: Proof-of-Concept Study (Preprint)
Authors: CHATTERJEE AYAN , Prinz Andreas
Published: August 2021

BACKGROUND

Interoperability is a challenge in healthcare information systems because of heterogeneity in semantic and technical levels of data. It creates a problem in exchanging data from different sources. Person-Generated Health Data (PGHD) is health-related data created, recorded, or collected by individuals or family members, or caregivers. PGHD can be captured passively and continuously to create a more accurate and comprehensive picture of the individual. PGHD is a category of Personal Health Records (PHR) that helps people to store and manage their health records. The rapid growth of PHRs and standards to exchange PHRs in a secure way have improved different aspects of health practices and personal care.

OBJECTIVE

This is a two-fold study. First, this study aims to investigate Health Level 7’s (HL7) new standard, Fast Healthcare Interoperable Resources (FHIR), as a standard format to explain information model (personal, physiological, and behavioral data from heterogeneous sources, such as activity sensor, questionnaire, and interview) and clinical terminologies together. Second, we explore the protocol’s advantages in some detail and critically analyze endpoint security of the HL7 application programming interface (HAPI).

METHODS

To address the interoperability problem, we combine FHIR and internationally acclaimed medical terminologies and use JavaScript object notion (JSON) to represent and exchange PGHD. We develop a secure digital infrastructure with TSD (services for sensitive data) as Infrastructure as a Service (IaaS), where we deploy the HAPI FHIR server as a docker image. We integrate the concepts such as authentication, authorization, and identity brokering to protect HAPI REST interfaces. PGHD inside TSD are protected following the Norwegian Data Protection Policies (NORMEN) and General Data Protection Regulation (GDPR). We use personal, physiological, and behavioral data involved in health monitoring and store them in the TSD database using the HAPI FHIR server. Storage and retrieval of PGHD from TSD are HL7 compliant.

RESULTS

First, we discuss storing PGHD in TSD and retrieving it from TSD following HL7 protocol using the HAPI FHIR server in JSON format, combining the information model and medical terminologies. Second, it describes how to secure HAPI REST APIs with the TSD platform.

CONCLUSIONS

FHIR resources can establish a coherent view of PGHD collected from heterogeneous sources by enabling flexible data exchange between stakeholders and service providers. Besides, the study reveals that TSD is a secure platform for the management of PGHD.

Medical Students’ Perceptions of a Blockchain-Based Decentralized Work History and Credentials Portfolio: Qualitative Feasibility Study (Preprint)
Authors: Hasselgren Anton , Kralevska Katina , Gligoroski Danilo , Faxvaag Arild
Published: August 2021

BACKGROUND

Increased digitization of health care might challenge some of the trust functions that are established in a traditional health care system. We have, with the concept of VerifyMed, developed a decentralized service for work history and competence verification, as a means to increase trust in the virtual interaction between a patient and a caregiver, mitigate administrative burden, and provide patient-reported outcomes seamlessly for health professionals.

OBJECTIVE

This research aimed to validate the use case of a decentralized credentials service for health care professionals in Norway. We also aimed to evaluate the proof-of-concept of VerifyMed, a blockchain-based credential service for health care professionals.

METHODS

A qualitative approach was applied with data collection through 9 semistructured interviews and 2 focus groups (one with 4 participants and the other with 5 participants). The System Usability Scale (SUS) was used as a part of the interviews. Data were analyzed through the principles of systematic text condensation. The recruitment of participants ended when it was concluded that the data had reached saturation.

RESULTS

The following 5 themes were identified from the interviews and focus groups: (1) the need for aggregated storage of work- and study-related verification, (2) trust in a virtual health care environment, (3) the potential use of patient feedback, (4) trust in blockchain technology, and (5) improvements of the VerifyMed concept. The SUS questionnaire gave a score of 69.7.

CONCLUSIONS

This study has validated the need for a decentralized system where health care professionals can control their credentials and, potentially, their reputation. Future work should update the VerifyMed system according to this input. We concluded that a decentralized system for the storage of work-related verifiable credentials could increase trust in a virtualized health care system.
Perceived barriers to psychiatric help-seeking in South Korea by age groups: Text mining analyses of social media big data (Preprint)
Authors: Seo Hwo Yeon , Song Gil Young , Ku Jee Won , Park Hye Yoon , Myung Woo Jae , Kim Hee Jung , Baek Chang Hyeon , Lee Nami , Shon Jee Hoon , Yoo Hee Jeong , Park Jee Eun
Published: August 2021

BACKGROUND

In South Korea, the psychiatric treatment gap is huge. Sociocultural context, such as stigma attached to mental illness, limit opportunities for professional help-seeking.

OBJECTIVE

This study uses TM of the internet to investigate barriers by age groups to receiving psychiatric treatment.

METHODS

A corpus of data was collected from web communities, social network services, and personal blogs on the internet from 1 January 2016 to 31 July 2019. Words frequently linked with psychiatry were collected by natural language processing. Words that may be associated with barriers to receiving psychiatric help were identified and categorized. Because the data from web communities could be classified approximately according to age, the analyses were arranged by age groups.

RESULTS

A total of 97,730,360 articles were identified for the period in question, among which 6,097,369 texts contained keywords relevant to psychiatry. Among words that were associated with ‘psychiatry,’ approximately 3,000 were selected based on their frequency of occurrence. Words associated with barriers to receiving psychiatric help were categorized into the following four groups: structural discrimination, public prejudice, low accessibility, and adverse drug effects. Structural discrimination was the greatest barrier (34%), followed by public prejudice (27.8%), adverse drug effects (18.6%), and cost/low accessibility (16.1%). Structural discrimination was the greatest barrier in the groups consisting of teenagers (51%), job seekers (64%), and young mothers (43%). However, in the seniors group, the greatest barrier was public prejudice (49%).

CONCLUSIONS

Structural discrimination is the greatest barrier to receiving psychiatric help in Korea. Difference in the barriers, however, exists among age groups. As well as addressing structural issues for all, more tailored approaches may be required by generations to lower the gap.

Land Use Land Cover Analysis using Geospatial Techniques
Authors: Singh Babita
Published: August 2021

Abstract: Remote sensing and Geographic information system (GIS) techniques can be used for the changing pattern of landscape. The study was conducted in Dehradun, Haridwar and Pauri Garhwal Districts of Uttarakhand State, India. In order to understand dynamics of landscape and to examine changes in the land use/cover due to anthropogenic activities, two satellite images (Landsat 5 and Landsat 8) for 1998 and 2020 were used. Google Earth Engine was used to perform supervised classification. Spectral indices (NDVI, MNDWI, SAVI, NDBI) were calculated in order to identify land cover classes. Both 1998 and 2020 satellite images were classified broadly into six classes namely agriculture, built-up, dense forest, open forest, scrub and waterbody. Using high resolution google earth satellite images and visual interpretation, overall accuracy assessment was performed. For land cover/use change analysis, these images were imported to GIS platform. Landscape configuration was observed by calculating various landscape metrices Images. It was observed that scrub land area had increased from 11 % to 14 % but a decrease in agriculture by 4.65 %. The increased value of NP, PD, PLAND, LPI and decrease in AI landscape indices shows that land fragmentation had increased since 1998. The most fragmented classes were scrub (PD - 3.32 to 5.18) and open forest (PD - 3.57 to 5.07). Decrease in AI for open forest, agriculture, built-up indicated that more fragmented patches of these classes were present. The result confirmed increase in the fragmentation of landscape from 1998 onwards. Keywords: GIS, LULC, landscape metrics, Remote Sensing

Published: August 2021

Abstract: The production of self-compacting concrete SCC is a relatively new technology. Nowadays, the production of SCC is becoming more popular. However, the production of SCC requires more sensitive and efficient workmanship and equipment. This research presents the fresh and hardened properties of self-compacting concrete (SCC) containing plastic bag waste fibers (PBWF). Fibers were prepared by using waste plastic bags. Plastic bag waste fibers (PBWF) are used in varying percentages of fibers (0.5, 1, and 1.5%) replacement by weight of fine aggregate. L-box, U-box, and V-box tests were performed to assess the fresh properties of the prepared mixtures. The compressive strength of the concrete(M-30) was determined. Test results show that mixtures based on PBWF with 0.5%, 1%, and 1.5% met the criteria of self-compactibility (evaluated by U -box, L-box, and V-box) regardless of the fibers content. This research consists of (i) the development of a suitable mix for SCC containing PBWF that would satisfy the requirements of the workability; (ii) casting of concrete samples and testing them for compressive strength for 7days, 14days, and 28days.

Abstract: The capillary tube is commonly employed in refrigerant flow control systems. As a result, the capillary tube's performance is optimal for good refrigerant flow. Many scholars concluded performance utilising experimental, theoretical, and analysis-based methods. This paper examines the flow analysis of a refrigerant within a capillary tube under adiabatic flow circumstances. For a given mass flow rate, the suggested model can predict flow characteristics in adiabatic capillary tubes. In the current work, R-134a refrigerant has been replaced by R600a refrigerant as a working fluid inside the capillary tube, and the capillary tube design has been modified by altering length and diameter, which were obtained from reputable literature. The analysis is carried out using the ANSYS CFX 16.2 software. The results show thatutilising a small diameter and a long length (R600a refrigerant flow) is superior to the present helical capillary tube. The most appropriate helical coiled design with a diameter of 0.8 mm and a length of 3 m is proposed. Keywords: Capillary Tube, Condenser, Refrigeration effect, CFD.
Rerouting of Middle Bench Conveyor System in Mine for Optimization of Length and Power Consumption
Authors: A Joel Josiah
Published: August 2021

Abstract: In Neyveli Lignite Corporation, belt conveyors are used for transporting coal and overburden soil from mines to storage yards and dump yards respectively. Conveyor belt with carrying capacity upto 20,000T/hour is used for transportation of materials. The power consumption of the conveyor system depends on the length of the conveyor. Power consumption is high for a long routed conveyor system and less for a short routed conveyor system. The conveyor system is rerouted to the shortest possible way for optimizing length and power consumption of the conveyor system. By this rerouting, the cost of power consumption will be reduced. Keywords: conveyor system, power consumption, rerouting, mine, length
Students’ Mathematics Self-Concept, Mathematics Anxiety and Mathematics Self-Regulated Learning during the Covid-19 Pandemic
Authors: Delima Nita , Cahyawati Dian
Published: August 2021

Online learning during the Covid-19 pandemic requires lecturers to provide a stimulus that can increase student learning independence. However, not all lecturers and students are ready to carry out online learning, as a result, the anxiety factor for students is getting higher. In some studies, it is said that anxiety has a negative correlation with student self-concept. This study aims to find out how the mathematics self-concept (MSC), mathematics anxiety (MA), and mathematics learning independence (MSRL) of students are during the Covid-19 pandemic. This research is quantitative descriptive. The population of this study was active students in the Mathematics and Mathematics Education study program. Data were collected using a cross-sectional survey technique with cluster sampling. The data analysis technique used descriptive statistical analysis, Spearman correlation analysis, and ordinal regression analysis. The results showed that the average student had a positive MSC, MA, and moderate MSRL. Students with negative MSC had a significant tendency to have a high MSRL than students with positive MSC. The increasing probability of students with negative MSC having a high MSRL is 0.5110 times better than students with positive MSC. MSC and MA have an effect of 7.9% on changes in the student's MSRL variable. Thus, during the Covid-19 pandemic mathematics self-concept directly affects changes in student learning independence, but not with math anxiety.

Integrating mathematics into local culture is a way to enhance students' interest in local wisdom. The concept of mathematics is explored to find out the existence of mathematics in society's culture which has not been seen so far. The Mathematical concept is used to explore the existence of mathematics in terrace culture on the Panyaweuyan terrace of Majalengka city. This study to describe the result of exploratory project-based learning of the Panyaweuyan terrace with this kind of exploratory research. The exploring of the relationship between the terrace culture of panyaweuyan and concept mathematics, especially in the concept of arithmetic sequences is analyzed and described through literature studies, observation, and interviews with 4 informants who are local farmers. The results that there is a relationship between the arithmetic sequence concept with the local culture of Panyaweuyan Majalengka city. The results of the study stated that each mound on each step on the Panyeweuyan terraces was formed through an arithmetic sequence formula. Farmers in Panyaweuyan terraces are naturally able to make terraces according to the arithmetic sequence formula without knowing the basics of mathematics. Therefore, the concept of mathematics is part of local culture which has an important role in preserving the nation's culture.
Keeping cultural codes: the customs and ceremonies of ethnic minorities under Russian rule
Authors: Trepavlov Vadim V.
Published: August 2021

When establishing its rule over other nationalities, the Russian Empire relied on local elites, including their aristocracy, tribal chiefs, and sometimes the clergy. In addition to retaining some of their traditional privileges, they were also granted new benefits. The same paradigm applied to the ethnic policy of both the Muscovite state and the Russian Empire: a combination of nation-wide standards of citizenship and management with local traditional principles of organizing society. The cultural codes of Russian officials and settlers on the one hand and the expanding states non-Slavic population on its the eastern and southern frontiers overlapped and influenced each other. To lessen the opposition of its minorities, the empires administration often adapted new regulations to their cultural norms. For pragmatic reasons, officials acknowledged the importance of at least showing some respect to subjects who spoke different languages and professed different beliefs. As a result of this interaction, the cultures of the rulers and the non-Russian nationalities they ruled influenced each other.
Missionary activities of the Russian orthodox church in Southeast Asia at the beginning of the 21st century

The article analyses the Russian Orthodox Churchs missionary activity of the in Southeast Asia, with a focus on its prerequisites and the stages of its development. ROC missionary work in the region could build on the experience of pre-revolutionary spiritual missions in Asia, as well as on the Orthodox communities of Russian emigrants after the revolution. Important factors are also the formation of the global labor market; international tourism; and the aspiration of compatriots living abroad to preserve the Russian World (Russkii Mir). The article analyses the Russian historiography of the missionary activity of the Russian Orthodox Church in Southeast Asia. With the establishment of the Patriarchal Exarchate in Southeast Asia in 2018, with its center in Singapore, a new stage of missionary activity in the region began. The establishment of the exarchate in Southeast Asia brought about the systematical management of the numerous Orthodox parishes that appeared at the turn of the millennium in this region. Relying on little-known and understudied historical sources, the authors identified the forms of missionary work in various countries and assessed the scale of activities in relation to the prevailing confessional traditions. This includes an analysis of missionary work in countries dominated by Buddhism (Thailand, Cambodia, Laos), Christianity (the Philippines), and Islam (Indonesia, Malaysia), with special attention paid to the situation in socialist Vietnam and multi-confessional Singapore. The authors conclude that the missionary activity of the Russian Orthodox Church in Southeast Asia has now passed through several stages from the emergence of the first Orthodox communities in the region to the formation of centralized structured management of the numerous new parishes, with missionary work conducted in ways that respond to the local characteristics.
