Authors: Nirlipta Priyadarshini Nayak , Vamsi Krishna Kudapa
Published: March 2023

To prevent pollution of air, water, and land resources as well as the transfer of dangerous chemicals, waste must be seen as a potential resource, rather than something undesired and unwanted. The pace of trash production rises in tandem with population growth and industrialization. Mismanagement of municipal solid waste (MSW) has negative environmental consequences, puts public health at risk, and raises a number of other socioeconomic problems worth addressing. A well-thought-out decision-making policy will significantly enhance the quality of the municipal solid waste management (MSWM) process. We require well-planned and well-designed municipal waste management systems to correctly anticipate the MSWM system. Many urban and rural regions in India have long struggled with waste management issues. People in rural regions let garbage decay and use it as fertilizer on their agricultural fields. As technology advances, different methods are being used to turn trash into energy. This article focuses on the need for trash to be converted into energy as well as other current techniques.
A review of reverse osmosis process for seawater desalination
Authors: Kumargaurao D. Punase
Published: March 2023

The freshwater availability in many regions of the world has been a rising concern for the last few decades due to disturbing increase in population, urbanization, and industrial advancement. As water consumption is increasing year by year, the obvious solution to the freshwater shortage is to increase its supply. Desalination has been a prominent process to produce fresh water in numerous water-stressed regions to counteract the water shortage issues. Amongst the various desalination methods, the reverse osmosis method is used for generating fresh water from saline or brackish water by removing salts to make it suitable for human utilization, agriculture, and industrial purposes. In the present study, a systematic review of the seawater reverse osmosis process is presented to address the developments in the pretreatment, membrane, and post-treatment processes of reverse osmosis.

Emotions are states of readiness in the mind that result from evaluations of one's own thinking or events. Although almost all of the important events in our lives are marked by emotions, the nature, causes, and effects of emotions are some of the least understood parts of the human experience. Emotion recognition is playing a promising role in the domains of human-computer interaction and artificial intelligence. A human's emotions can be detected using a variety of methods, including facial gestures, blood pressure, body movements, heart rate, and textual data. From an application standpoint, the ability to identify human emotions in text is becoming more and more crucial in computational linguistics. In this work, we present a classification methodology based on deep neural networks. The Bi-directional Gated Recurrent Unit (Bi-GRU) employed here demonstrates its effectiveness on the Multimodal Emotion Lines Dataset (MELD) when compared to Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM). For word encoding, a comparison of three pre-trained word embeddings namely Glove, Word2Vec, and fastText is made. The findings from the MELD corpus support the conclusion that fastText is the best word embedding for the proposed Bi-GRU model. The experiment utilized the "glove.6B.300d" vector space. It consists of two million word representations in 300 dimensions trained on Common Crawl with sub-word information (600 billion tokens). The accuracy scores of GloVe, Word2Vec, and fastText (300 dimensions each) are tabulated and studied in order to highlight the improved results with fastText on the MELD dataset tested. It is observed that the Bidirectional Gated Recurrent Unit (Bi-GRU) with fastText word embedding outperforms GloVe and Word2Vec with an accuracy of 79.7%.

Published: March 2023

This paper takes a holistic look into Patagonia's marketing strategy that reflects its out-of-the ordinary viewpoint on the industry it operates in. With a short look into the pressing issues of the fashion industry, a focus on Patagonia's own weaknesses as well as its attempt to fix the same reveals a very successful and mostly authentic sustainability marketing strategy that has helped the business become increasingly successful in its own bottom line while raising awareness for the need to change. The methodology that is employed in this case study is qualitative in nature and uses primarily secondary sources. The case research suggests that the firm has significantly impacted the social outdoor fashion sector, and it has maintained a consistent and expanded focus on environmental and social responsibility goals and objectives. Patagonia has not discarded its values and priorities for the sake of making profit, even during the disruptive impact that the outbreak of the global coronavirus pandemic has had on the supply chain, demand, and profits.
A study on fintech revolution in india: A review
Authors: Prakash N. , Indiradevan Y. , Subhasri P.
Published: March 2023

Through innovation and technology, traditional financial services have undergone a significant transition. Today, technology seems to be a key component in the growth of digital economy. With the rising market and technical improvements, Indian banking sectors and financial service providers have purposefully adopted technology over the years to enhance client reach, service delivery, and operational work efficiency. However, the adoption rate of financial technology is still lagging below its potential. Therefore, there are gaps in the provision of financial services. Banks and financial institutions have learned that technology has the power to entitle current business conceptions rather than creating new business proposals themselves. However, the use of digital technologies to create new business opportunities and target underserved market niches is changing how financial technology companies are seen. FinTech is the term used to describe the proper application of financial technology to the delivery of new financial services and products to untapped market segments in a way that is both moral and effective. From a business model perspective, the financial technology sector is made up of technology companies that either work with well-established banks and financial institutions to offer essential customer and market data or strive to do away with intermediaries altogether. FinTech is attracting and increasing interest from investors, regulators, payment banks, NBFCs, traditional banks, payment service providers, broking and wealth management firms, insurance firms, and pure-play FinTech operators, to name a few of the sector's major players in India's financial services. The goal of this study is to discuss the various facets of fintech in India.

Published: March 2023

With technology's increasing capabilities, social media has become the largest pool of data from which it can extract public opinion and begin to gather informative data on the success or failure of a brand, product, or marketing campaign in the eyes of the public. People share their experiences, opinions, and daily activities on social media, which results in enormous amounts of online data that attract developers to carry out data mining and analysis. Thus, there is a necessity for social media screening to obtain results that can be used for analysis. Twitter is an online networking site driven by tweets, which are 140-character limited messages. Thus, the character limit enforces the use of hashtags for text classification. Currently, around 5500–6000, tweets are published every second, which results in approximately 561.6 million tweets per day. Performing sentiment analysis of tweets can help us to determine the polarity and inclination of a vast population toward a specific topic, term, or entity. The applications of such analysis can easily be observed during public elections, movie promotions, brand endorsements, and many other fields. This proposed system uses a Naïve Bayes classifier to determine the tweets based on sentiment. In the implemented system, tweets are collected, and sentiment analysis is performed on them. Based on the sentiment analysis results, a few suggestions can be provided to the user. The primary aim is to provide a method for analyzing sentiment scores based on grades. This paper reports on the design of sentiment analysis, extracting vast numbers of tweets. Results classify users' perceptions via tweets into positive and negative categories. Secondly, it discusses various techniques to carry out a sentiment analysis on Twitter data in detail.
Should parents be allowed to stay with minors during procedures in hospital?
Authors: Anny Ashiq Ali
Published: March 2023

Parenting is the biggest sacrifice one can make. It is putting you on hold to fulfill the promise of your child's tomorrow. Parents' presence acts as a morale catalyst during the treatment of a sick child. Although parental involvement in the treatment of hospitalised children is now regarded as essential, it remains one of the concepts on which there is no agreement. Parents' involvement and care during the procedures for hospitalised children also defines how parental involvement alleviates parent-child anxiety and prevents post-traumatic stress disorder. On the contrary, parental presence violates the privacy of healthcare team members and also increases their anxiety.
A model-free gait recognition approach for person identification with covariates
Authors: Surekha Samsani
Published: March 2023

In the present scenario, the identification of abnormal activity in the crowd plays a vital role in the detection of criminal and mental activities. Gait can be utilized for person authentication and can be used in surveillance where a large number of people pass through. Gait recognition is an evolving biometric technology, which involves people being recognized purely through walking manner. It is an interesting research topic as gait can be obtained without a person's cooperation, and gait has a unique nature. At present, the methods being used for gait recognition can be broadly divided into two categories, model-based, and model-free approaches. The model-based approach requires prior modeling to generate gait features, which requires high computational costs, whereas the model-free approach directly extracts features from silhouette frames. The main challenge faced by a model-free approach is that it is sensitive to covariate conditions such as clothing, carrying objects, and walking surfaces. This paper presents a modelfree approach that is very effective at handling known and unknown covariates. In this paper, two popular methods, namely, Convolutional Neural Network (CNN) and discriminative feature-based classification methods, are used for gait recognition. The CNN-based method is used for known covariates, and the discriminative feature-based classification method is used for unknown covariate conditions. The Chinese Academy of Sciences (CASIA) Gait Database B from the Center for Biometrics and Security Research (CBSR) is used to train the models and their performance is evaluated in terms of Accuracy, Precision, Recall, and F1-Scores.
Demotivating factors experienced by teacher educators in synchronous distance education: A hermeneutic phenomenology research
Authors: Cenk Akay
Published: March 2023

Just like every system, distance education also has disadvantages as well as advantages. The aim of the study is to examine the experiences of the teacher trainers about the difficulties or problems that demotivate them in synchronous distance education applications from a hermeneutic phenomenological point of view and to explain in detail their justifications. In this study, attention was paid to the fact that the teacher trainers had synchronous distance education experience of at least two years. The research participants were chosen in accordance with the purposive maximum variation sampling strategy. Eleven teacher trainers consented to participate. As a result of the research, it was concluded that the teacher trainers were partly demotivated in the synchorous distance education process. Different sources of this demotivation were obtained from the findings of the trainers based on their experiences. Accordingly, it has been concluded that the factors that demotivate the trainers are, technological and physical infrastructure problems, hardware inadequacies, problems arising from the characteristics of the platforms used, the inadequacies and inexperience of the trainers themselves in synchronized distance education, the unwillingness of the students in this process, the technological inadequacies and problems students experience in synchronized distance education, the inability to effectively measure and evaluate pedagogically, the inability to implement different teaching methods in the classroom, the inadequacies of the instructional programmes and course materials, the inability to create a studentteacher and student-student interaction.
Differential item functioning across gender on three subtests of EGMA
Authors: Brian Mumba
Published: March 2023

Researchers in educational measurement use Differential Item Functioning (DIF) to examine whether test items are functioning uniquely across subgroups of test participants while taking into account their ability level. DIF is essential for test validity arguments, thus making it a necessary part of validity studies. This study examines DIF across gender on three subtests of the Early Grade Mathematics Assessment (EGMA) (number identification, number discrimination, and recognition of number patterns) using a logistic regression procedure. Study participants were Grade 2 and Grade 3 primary students who participated in the 2018 Early Grade Mathematics Assessment Survey in Zambia. The study employed a three-step logistic regression procedure on test items for number identification, number discrimination, and recognition of number patterns to determine whether DIF was present or not. The results, on the whole, show that none of the subtest items of number identification, number discrimination, and recognition of number patterns showed DIF.

Authors: Peter Makaya
Published: March 2023

The study used a phenomenological design with semi-structured interviews to explore rural teachers' preparation for inclusive education in Zimbabwe. A sample of 20 teachers from 20 primary schools in Gutu District were interviewed, along with various aspects related to their knowledge of inclusive education and strategies for including learners with autism in mainstream classrooms. The study revealed that most rural school teachers have low knowledge and skills about inclusive education. It was also found that factors such as lack of in-service training, and lack of resources were among the challenges faced by rural teachers in preparing for inclusive education. It is concluded that effective inclusive education is still facing a lot of challenges in rural schools in Zimbabwe, and to make it a reality, the study recommends that the Ministry of Primary and Secondary Education (MoPSE) and educational stakeholders work together with rural teachers to ensure the availability of equipment and materials for effective learning for both learners with and without autism. The study recommends that, provision of regular in-service training and workshops could help many teachers gain appropriate knowledge and skills in teaching learners. Furthermore, rural schools are challenged to provide the latest technological developments and adequate resources to facilitate inclusive learning.
A novel approach for content-based mining and indexing using hierarchical ranking
Authors: Rupesh Mishra , Rajesh Kumar Pathak
Published: March 2023

The development of multimedia technologies is becoming more popular; users are not satisfied with traditional information retrieval techniques. People shared ideas and information with others by using methods of communication such as eye contact, movement, interaction through gestures, verbal and written communication. In data recovery, ranking is a key concept. Despite the importance of highlight choosing, calculations for picking ranking models have been thoroughly explored, but this is not the case for highlight choice. Numerous factor-determination methods used in the grouping are directly applicable to ranking. It recovers the natural color, surface, and shape information of images for effective component extraction using edge identification, which is frequently used in signal processing and picture pressure. It has observed the use of information-digging techniques for finding covered-up designs in the enormous dataset and addressing problems in various scientific domains. This paper inputs maximum number of files, and it has voice-based statements or keywords in it. Voice commands convert the voice into text and start searching the text into a file. This will be done by content-based mining, which will be comparable to word-based mining or data mining, using a hierarchy pattern to decide its priority irrespective of its supportive words.

Published: March 2023

Concrete is widely used as a construction material in the world and consequently cement manufacturing industry ranks second in CO2 emission. To mitigate this environmental issue, this research focuses on reducing the self-weight of a concrete slab applying modern techniques to cut down the usage of cement, cutting carbon emissions from the cement manufacturing industries. The main goal of the study is to reduce the self-weight of concrete slabs and to eliminate steel reinforcement in concrete, and to use this stress profile to determine the isostatic path in concrete slabs. This would be achieved with high-strength concrete in the maximum bending stress path and replaces foam or other material in the minimum bending stress zone. In this work, the specimen considered for design and analysis is a slab having the dimension of 3 m x 3 m x 0.125 m. It slab uses 1% of steel fibers in concrete eliminating the need for reinforcement. Also, with the use of high-strength concrete in the maximum bending stress zone, the self-weight of the slab reduces up to 44%. The deformation of the slabs are well within the limits recommended by the codes released by Bureau of Indian Standards (BIS).

This study investigated the effects of cryokinetics on hand function of subjects with spinal cord injury. The present study has an experimental design. Thirty-nine subjects with upper spinal cord injury were included. Handgrip and pinch strength were measured using electronic hand dynamometer (in kg) and mechanical pinch gauge (in kg) respectively prior to and following an 8-week cryokinetics. The amount of handgrip and pinch strength of both hands generated by each participant was used as a quantitative measurement of the development of hand function. Inferential statistics of multiple analysis of variance was used to analyze the data. Statistical significance was retained for p value <0.05. The results of this study revealed that the strength training and the cryotherapy programmes separately had insignificant (p>0.05) effects on the hand function of the subjects. However, cryokinetics had significant (p<0.05) effects on the hand function of subjects with upper spinal cord injury. It was therefore concluded that the strength training programmes and cryotherapy individually cannot substantially influence hand function of subjects with upper spinal cord injury whereas, cryokinetics can substantially enhance hand function of the participants. Thus, cryokinetics is an excellent intervention protocol for optimizing hand function of subjects with upper spinal cord injury. It was therefore recommended that cryokinetics should be regarded as keystone in the management of subjects with upper spinal cord injury.

The world’s leading health institutions warn that adolescents do not meet the minimum level of physical activity necessary for the proper physical development of young people, which is considered one of the main problems of public health. In addition to personal preference, environmental and cultural factors play an important role in the involvement of young people in sports. This study aimed to examine potential differences in involvement in sports, anthropometric characteristics and motor abilities, in adolescents of different residential statuses. The sample included 83 adolescents, of whom 45 (54.2%, 13.51±0.55 yrs) were from urban areas and 38 (45%, 13.45±0.50 yrs) were from rural areas in the Belgrade region. Surveying detected their involvement in sports, and anthropometric characteristics were assessed through body height (BH) body mass (BM), body mass index (BMI), and motor abilities through explosive strength of lower and upper extremities and agility. A Mann-Whitney U test has shown that place of residency impacts involvement in sports and motor abilities, while there was no impact on anthropometric characteristics. Cohen’s criteria (r) detected the level of impact. Adolescents from urban areas are more involved at sports and have better motor abilities. There is no difference in anthropometric characteristics. Considering the relatively small sample of respondents and variables assessed, the obtained results can hardly be generalized. However, this does not diminish the importance of the present study which examined the urban-rural state of sports activity, anthropometric characteristics and motor abilities of adolescents in Serbia, thus making an important contribution to this field.

Authors: PACANOSKİ Zvonko , MEHMETİ Arben
Published: March 2023

The field experiments were carried out during 2017 and 2018 on commercial rice field in Kochani region to assess different POST-em herbicide programs for weed management in lowland flooded rice system in North Macedonia. In addition, herbicide selectivity and impact on rice grain yield were estimated. POST-em herbicide treatments were used in early-(EPOST-em), mid-(MPOST-em) and late-(LPOST-em) rice growth stages (BBCH 26; 29 and 32-34, respectively). Weed control varied among herbicide treatments, herbicide programs, and weeks after treatments (WAT). All herbicides applied EPOST-em controlled Echinochloa crus-galli (ECHCG) and Scirpus maritumus (SCMA) 91-100%. At MPOST-em treatment, herbicides showed control of ECHCG between 93 and 97%. However, all herbicides applied LPOST-em controlled ECHCG 79-88%. SCMA control was less than 88 and 85% with MPOST-em and LPOST-em treatments, respectively, perhaps as a consequence of progressive growth stage of SCMA (BBCH 40). Control level of Cyperus rotundus (CYPRO) and Heteranthera reniformis (HETRE) was high in all POST-em treatments (between 90-100%, and 95-100%, respectively). EPOST-em and MPOST-em application of any herbicide resulted no phytotoxicity to rice plants. LPOST-em treatments caused rice phytotoxicity by cyhalofop-butyl + penoxsulam, cyhalofop-buthyl + bentazon, and profoxidim + bentazon which were ranged from 8-20%. Unlike rice yield at LPOST-em treatments was 6235 kg ha-1, all EPOST-em and MPOST-em used herbicides has impact in rice yield 6685 and 6610 kg ha-1, respectively which, but there were no statistically significant differences with the weed free control 6710 kg ha-1.

Factors of non-specific immunity are responsible for protecting birds from a number of viruses and bacteria. Bactericidal proteins are played here lysozyme and complement, interferon, as well as beta-lysine. Adding appropriate active compounds to the bird's diet to activate the innate immune response are subject to studies by many authors. The practical application and influence of the "Avigen Duck". immunomodulator in the cultivation of White Pekin ducks aims to clarify the dynamics of the indicators. It was found that the ducks treated with the immunomodulator had higher non-specific protection expressed in the values of the observed indicators. Complement activity for the experienced group (529.45 ± 17,85 CH50) is significantly higher than that of untrained birds (308.56 ± 10.19 CH50), on the 30th day of their lives (P <0.001). Lysozyme values for the experienced group (6.34 ± 0.86 mg L-1) is more than twice as high as its concentration in control birds - 2.52 ± 0.59 mg L-1. At 30 days of age, the mean concentration of IFN γ in the control group of ducks was 108.86±6.12 pg ml-1, and in the experimental group treated with immunomodulator - 518.06±12.80 pg ml-1, accompanied by an increase in the values of IL-2 and IL-6 and beta-lysine activity. These data show that, despite the short life of the ducks, the concentrations of the investigated factors of non-specific immunity increase significantly and statistically reliably, even after a single treatment with immunomodulator "Avigen Duck". The practical application of the immunomodulator in the duck diet has a strong effect on their non-specific immunity.

Discovering the variation among genotypes is an important criterion for selecting the suitable cultivar for a certain environment. The study aimed to explore the genetic variation among 17 genotypes of barley based on grain yield and some related traits. Plants were grown under field grown conditions in the 2019-2020 and 2020-2021 growing seasons, and plant height (PH), spike per square meter (SSM), spike length (SL), spikelets per spike (NSS), seed per spike (SPS), biological yield (BY), grain yield (GY), and thousand grain weight (TGW) were measured. Results indicated that PH ranged (51.7 to 81.33 cm) and (58.20 to 79.90 cm), SSM (374 to 582) and (418 to 701), SL (7.10 to 9.63 cm) and (6.87 to 9.13 cm), NSS (9 to 15) and (8 to 17), SPS (21 to 49) and (21 to 51), BY (3466.7 to 5905.3 kg h-1) and (3731.7 to 6080 kg h-1), GY (1442 to 2192 kg h-1) and (811.8 to 1763.7 kg h-1), TGW (34 to 55.67 g) and (33.47 to 52.63 g) for the first and second year of experiment respectively. The advanced lines measurement values were higher in the second year of the experiment. It can be concluded that the advanced lines Anka-08 and Anka-11 are promising in most of the parameters. Some of the old and new cultivars still preserve their yield potential.

Indonesia is one of the world's ornamental fish exporting countries. Demand for Indonesian ornamental fish from major importing countries such as United States, China and Singapore. In terms of meeting the demand of the ornamental fish market in importing country, Indonesia is still inferior to other countries such as Philippines. The purpose of this study is to analyze the factors that influence demand volume of Indonesian ornamental fish imports in United States, China and Singapore. The time period used was from 2000 to 2018. Data sources were taken from UN Comtrade and World Bank. The research method used is descriptive analysis and quantitative analysis using Ordinary Least Square. The results of this study indicate the volume of important demand for Indonesian ornamental fish in United States and Singapore has a negative trend while in Chinese market it has a positive trend. Then factors that influence the demand for Indonesian ornamental fish in United States are price of imported Indonesian ornamental fish, price of imported competence, and exchange rate of the rupiah against the US dollar. In Chinese market, this is influenced by price of Indonesian ornamental fish and the exchange rate of the rupiah against the yuan. While in the Singapore market this is influenced by price of Indonesian ornamental fish.
