Deprivation in education amidst covid-19 pandemic crisis

The education sector is one of the most affected areas by the pandemic. It caused a huge chasm that could affect the teaching-learning industry in the future. Although it is possible to have deprivation in education, the concept must not be embraced. Instead, HEI should focus on developing new and innovative ways of delivering education constructively. This paper focuses on the importance of both research and teaching in education. The two areas are identified and analyzed respectively to adopt innovative methodologies to enhance productivity in a higher learning institute. This paper intends to propose relevant teaching and learning methods to benefit the students, the university, and society. This paper utilizes several factors involved in the pandemic crisis and suggests ways to use several methods to regenerate the learning environment without hassle.

Effective key management in dynamic wsn

Recently, wireless sensor networks (WSNs) have been deployed for a wide variety of applications, including military sensing and tracking, patient status monitoring, traffic flow monitoring, where sensory devices often move between different locations. Securing data and communications requires suitable encryption key protocols. In this paper, we propose a certificateless-effective key management (CL-EKM) protocol for secure communication in dynamic WSNs characterized by node mobility. The CL-EKM supports efficient key updates when a node leaves or joins a cluster and ensures forward and backward key secrecy. The protocol also supports efficient key revocation for compromised nodes and minimizes the impact of a node compromise on the security of other communication links. A security analysis of our scheme shows that our protocol is effective in defending against various attacks.We implement CL-EKM in Contiki OS and simulate it using Cooja simulator to assess its time, energy, communication, and memory performance.

Ataque de nervios: the impact of sociodemographic, health history, and psychological dimensions on puerto rican adults

Introduction Ataque de nervios (ADN) is a cultural syndrome prevalent in Puerto Ricans characterized as an episode of intense emotional upset due to overwhelming stress. Methods The Ataque de Nervios Questionnaire , developed at the Center for the Study and Treatment for Fear and Anxiety (CETMA), served as the diagnostic tool for this retrospective secondary data analysis. We evaluated three models regarding ADN’s function as a marker of (1) sociodemographic vulnerability, (2) health history risk, and (3) psychological vulnerability. This last model was subdivided to assess the scores of screening tests regarding anxiety (Anxiety Sensitivity Inventory, Beck Anxiety Inventory, and State-Trait Anxiety Inventory), affect (Beck Depression Inventory, Emotional Dysregulation Scale, Positive and Negative Affective Schedule), personality (NEO Five-Factor Inventory), and trauma (considering the responses to the Childhood Trauma Questionnaire and the Life Event Checklist). Results Our study sample had a total of 121 Puerto Rican adult patients from CETMA out of which 75% had ADN. We differentiated subjects according to their ADN status with t-tests and Mann-Whitney U tests and evaluated our models using logistic regressions. People with ADN showed more anxiety, depressive symptoms, emotional dysregulation, and negative affect than those without ADN. They also revealed lower positive affect and agreeableness. Highly extraverted but minimally agreeable personalities related to ADN. Living with a partner and being employed were risk factors for ADN. Having higher educational levels showed the strongest effect size: it greatly reduced the odds of an ataque . Discussion These characteristics suggest a distinct profile of ADN seen in employed, educated, adult Puerto Ricans living on the Island experiencing anxiety. Our study provides clinical tools to comprehend our patients’ ADN experience, enriching our practice as culturally competent health providers.

Dimethyl sulfoxide in cryopreservation: an overview

Cryopreservation is a process that preserves intact living cells, tissues or any other biological constructs by cooling and storing the samples to very low temperatures in order to maintain their viability and to save them for future use. At very low temperatures, enzymatic and chemical activities that may cause harm to the biological material are effectively stopped. Cryopreservation methods look to reach very low temperatures without causing further harm caused by the creation of ice crystals during freezing. Cryopreservation human samples for storage including variety of diseases such as cancer, genetic and degenerative disorders and bio-banking. This review aims to describe and highlight dimethyl sulfoxide in cryopreservation. Dimethyl sulfoxide is a non-toxic solvent and is one of the most commonly used pharmaceutical agent with a varied range of pharmacological actions including membrane penetration, anti-inflammatory effects and local analgesia as well as weak bacteriostatic. The main use of dimethyl sulfoxide is a vehicle for some drugs to enhancing the action of the drug and helping penetration of other drugs into the skin. However, dimethyl sulfoxide has been the cryopreservative agent of choice in situation to its exceptional performance in mitigating freezing-related damages. It is frequently used in cell banking applications as a cryoprotectant. When added to media, it prevents intracellular and extracellular crystals from forming in cells during the freezing process. There has been a concern over the toxicity of dimethyl sulfoxide and its potential side effects in different highly concentration after administration to patients. Therefore, there has been growing demand for robust dimethyl sulfoxide for cryopreservation method that can improve safety and maintain potency and efficacy

Tomato leaf disease classification by exploiting transfer learning and feature concatenation

Tomato is one of the most important vegetables worldwide. It is considered a mainstayof many countries’ economies. However, tomato crops are vulnerable to many diseasesthat lead to reducing or destroying production, and for this reason, early and accuratediagnosis of tomato diseases is very urgent. For this reason, many deep learning modelshave been developed to automate tomato leaf disease classification. Deep learning isfar superior to traditional machine learning with loads of data, but traditional machinelearning may outperform deep learning for limited training data. The authors proposea tomato leaf disease classification method by exploiting transfer learning and featuresconcatenation. The authors extract features using pre-trained kernels (weights) fromMobileNetV2 and NASNetMobile; then, they concatenate and reduce the dimensionalityof these features using kernel principal component analysis. Following that, they feedthese features into a conventional learning algorithm. The experimental results confirmthe effectiveness of concatenated features for boosting the performance of classifiers.The authors have evaluated the three most popular traditional machine learning classifiers,random forest, support vector machine, and multinomial logistic regression; amongthem, multinomial logistic regression achieved the best performance with an averageaccuracy of 97%.

Recent approches of" impurity profiling" in pharmaceutical analysis: a review

Impurity is something that is impure or makes something else impure. An impure substance may be defined as follows: a substance of interest mixed or impregnated with an extraneous or usually inferior substance, from the standpoint of its usage, the drug substance is compromised in terms of purity even if it contains another material with superior pharmacological or toxicological properties. The impurity may be developed either during formulation, or upon aging of both API’s and formulated API’s in medicines. The presence of these unwanted chemicals, even in small amount, may influence the efficacy and safety of the pharmaceutical products. The impurities are not necessarily always inferior. Highly sophisticated instrumentation, such as mass spectra meters attached to a Gas Chromatography or HPLC, are inevitable tools in the identification of minor components (drugs, impurities, degradation products, metabolites) in various matrices. Present article reveals different impurities found in the API’s, methods for identifying them and the possible measures to deal with the interferences caused by them in pharmaceutical analysis.

Morphological and chemical traits associated with resistance against spotted pod borer, maruca vitrata in pigeonpea

Host plant resistance is an important tool for minimizing the losses in pigeonpea due to spotted pod borer, Maruca vitrata, which is the most threatening hidden pest of pigeonpea crop. Experiment was carried out to study the morphological and chemical traits in pigeonpea associated with expression of resistance to M. vitrata and their incidence in different sowing dates. The incidence of M. vitrata varied significantly among different sowing dates. Crop sown on D2 (1st week of July) resulted in maximum pod infestation by M. vitrata (13.1%). Minimum pod infestation (2.3%) and (2.9%) was recorded in D4 (3rd week of July) and D1 (3rd week of June) sown crop, respectively. Among different varieties, AL-201 registered lowest pod infestation (4.3%) as compared to Pusa-992 (7.9%). The non-glandular (type A), and glandular (type B) pod trichome density of top, middle and lower canopy of the plant and the pod wall thickness was responsible for the resistance to M. vitrata. Whereas, non-glandular (type C) pod trichomes, pod length, seed width and number of seeds per pod were associated with the susceptibility to spotted pod borer. Expression of resistance to M. vitrata pod infestation was associated with low amounts of crude protein and total soluble sugar and higher amount of fat content, phenol content and tannin content of seed as well as pod wall

Cold cook methods: an ethnographic exploration on the mythsof methamphetamine production and policy implications

Background Urban legends and myths are prevalent in drug-use environments. However, the distinction between myth and fact is not always clear. We found contradictory claims regarding the emergence of cold cook methods for producing methamphetamine when contrasting user-generated reports with official reports repudiating such methods as myths. Our aim is to open the topic for more academic discussion. Methods We examine cold cook methods of methamphetamine production revealed in our ethnographic study and interviews with former (n = 50) and current (n = 48) methamphetamine users. Data were collected in the suburbs of a large southeastern city in the United States. We compare the data with reports from law enforcement professionals and public health officials. Results Official reports claim the cold cook method described by users in our study is a myth and does not produce methamphetamine. Small-scale producers sell it as methamphetamine and users claim it has the same effect as methamphetamine. They are charged for possession and distribution of methamphetamine when caught with this drug. It appears the unintended consequences of recent policy aimed to reduce production and use of methamphetamine may be a user-friendly production method. We do not know the health implications at this time. Conclusion We do not make any definitive conclusions on the legitimacy of the stories or myths discussed here but instead suggest that labelling drug stories as myths might lead to dismissing facts that hold partial truth. The subsequent dismissal of cold cook methods among policy and public health officials risks a range of unintended consequences among vulnerable populations. We present our case for more research attention on the myths of methamphetamine production.

Models of data structures in educational visualizations for supporting teaching and learning algorithms and computer programming

Teaching and learning computer programming is challenging for many undergraduate first-year computer science students. During introductory programming courses, novice programmers need to learn some basic algorithms, gain algorithmic thinking, improve their logical and problem-solving thinking skills, and learn data types, data structures, and the syntax of the chosen programming language. In literature, we can find various methods of teaching programming that can motivate students and reduce students’ cognitive load during the learning process of computer programming, e.g., using robotic kits, microcontrollers, microworld environments, virtual worlds, serious games, interactive animations, and visualizations. In this paper, we focus mainly on algorithm visualizations, especially on the different models of data structures that can be effectively used in educational visualizations. First, we show how a vector (one-dimensional array), a matrix (two-dimensional array), a singly linked list, and a graph can be represented by various models. Next, we also demonstrate some examples of interactive educational algorithm animations for teaching and learning elementary algorithms and some sorting algorithms, e.g., swapping two variables, summing elements of the array, mirroring the array, searching the minimum or maximum of the array, searching the index of minimum or maximum of the array, sorting elements of the array using simple exchange sort, bubblesort, insertion sort, minsort, maxsort, quicksort, or mergesort. Finally, in the last part of the paper, we summarize our experiences in teaching algorithmization and computer programming using algorithm animations and visualizations and draw some conclusions.

Evaluation of four trichoderma spp. for the biological control of black bundle disease (cephalosporium acremonium) in maize

Four Trichoderma species with known biocontrol activity (T. harzianum, T. hamantum, T. viride and T. virens) were tested for their efficacy against Cephalosporium acremonium, a causal organism of Black bundle disease in maize. Interactions between the fungi were assessed in vitro to study mutual antagonisms. Among the four bio-agents, T. hamantum proved to be promising which showed maximum inhibition (51.3%) followed by T. virens (45.2%), T. harzianum (44.6%) and T. viride (20.3%). T. hamantum was also found to be hyperparasite on C. acremonium whereas, T. harzianum and T. viride showed mycelial deformation. The volatile toxicants released by all the Trichoderma spp. were inferior in inhibiting the growth of C. acremonium when compared to the control as evident by inverted plate technique. The results of in vivo experiments confirmed the results from the in vitro study and showed that all the four bio-agents significantly reduced the disease incidence of Black bundle disease.

Demarketing for sustainability: a review and future research agenda

In the context of emerging sustainability challenges, demarketing has continued to draw the attention of academicians and practitioners globally over the past few years. It is interesting to note that demarketing is as old as marketing itself, yet its application and scope have grown from the past two decades only. Kotler and Levy, (1971) has defined demarketing as “that aspect of marketing which deals with discouraging customers in general or a certain class of customers in particular on a temporary or permanent basis”. This systematic literature review attempts to enrich the discussion on demarketing research through a systematic and comprehensive review of 64 articles published between 2000 and 2022. Using TCCM framework, we present relevant theories, research contexts, study characteristics, and methodologies used in demarketing research. Our review (1) Presents a systematic and comprehensive overview of the research in demarketing over the last two decades (2) Examines studies in demarketing within the framework of ‘triple bottom line’ approach for sustainability (3) Suggests a suitable definition of demarketing considering its exorbitant application within the sustainability context (4) Identify gaps and sets agenda for future research. Our systematic literature review found that research in demarketing has been growing considerably over the past two decades, twice as much in the last decade compared to the previous decade with spill-over to new sectors. The literature review, through the lens of ‘triple bottom line’ approach, is able to establish that demarketing can be employed to effectively address the sustainability challenges encountered by policymakers and practitioners.

"flipping the language classroom:" effects of gamifying instruction in the english language proficiency of filipino esl students

The study aimed to determine the effectiveness of gamifying instruction in the English language proficiency of Grade 8 Filipino ESL students in one University in Bicol, Philippines, that offers Junior High School. The quasi-experimental single pretest-posttest design was used in the study. The researcher-made test which underwent series of validation was given before and after the intervention period to determine the level of English proficiency and level of effectiveness of the games. Statistical treatment was done employing frequency count, T-test and Analysis of Variance (ANOVA). The findings revealed that there was significant difference between the pretest and posttest of the respondents using gamification. Thus, it can be inferred that the games helped in improving the level of English proficiency of the Grade 8 students. The statistical test results disclosed further that the effectiveness of the three games introduced to the students were significantly high. With these findings, it was recommended that language teachers should use gamification as supplementary instructional material in improving the English proficiency of the students.

Educational access for tribal groups in telangana state

A state in southern India called Telangana has a rich and varied cultural history. There are numerous tribes in the area, and they have long coexisted peacefully with the environment. These tribes have distinctive traditions that have been handed down through the generations. The Gond, Koya, Lambada, and Banjara are notable tribes in Telangana. Over the years, these tribes have encountered several difficulties, such as land acquisition, displacement, and a loss of cultural identity. However, via several government initiatives and community-based programs, efforts are being undertaken to maintain their culture and give them more authority. Tribal Development has been in the agenda for discussion at several levels in different forums for quite some time and continues to be an important aspect for serious deliberation in Telangana, not only because of a significant portion of the tribal population but more importantly because of the inequality of their participation, both socially and economically. The conventional wisdom that the tribal population should not be integrated with the mainline population, does not cut ice any longer as tribals themselves are eager to participate in national development and construction. A major initiative to empower the tribals, in my view is through the provision of appropriate educational opportunities to the children of the tribal families, though the aspects like infrastructural and health are identified as critical inputs. The present book tries to disclose the situation of the Scheduled Tribes in Telangana State. Various eminent scholars and students, media friends delivered their observations through their research papers. As per the observations and findings, the book contains some valuable and instant suggestions for overall development of tribes that the Telangana State Government has to play a major role in this endeavour This article critically examines initiatives for greater participation in education by tribal communities in India, arguing that current policy does not effectively enough facilitate greater participation and may, in fact, go against the avowed principle of ensuring greater equity. The article relies on fieldwork-based study to support arguments for the need to be culturally sensitive in making appropriate provisions for the education of scheduled tribes in India. Reasons for high dropout rates and non-enrolment among tribal children are examined and some searching

Axiology of gender bias- and compliments of empowerment in the life of women empowerment.

Gender Bias is an ambivalent issue all over the world. Understanding the values of being a man on women by one another may solve many consequences in future. Gender Bias will be dismissed by empowering women in the society. Because of the Gender Bias particularly women are in despaired state. UNO and many organizations have taken many decisions and efforts to empower women which will reduce the impacts of Gender Bias. Even though women are empowered we didn’t get remarkable result yet. Even our society is ridicule get ride from traditional customs but women themselves are opponent for accepting new rules and liberations. Empowering women is a mandated one; it is not implemented properly empower must bring the equal rights to women.
