Investigating Problem Solving on Calculator Items in a Large-Scale Digitally Based Assessment: A Data Mining Approach
Authors: Jiang Yang , Cayton-Hodges Gabrielle A.
Published: March 2023

This exploratory study investigated the behaviors and content of onscreen calculator usage by a nationally representative sample of eighth-grade students who responded to items from the 2017 National Assessment of Educational Progress mathematics assessment. Meaningful features were generated from the process data to infer whether students spontaneously used calculators for mathematical problem solving, how frequently and when they used them, and the nature of the operations performed on calculators. Sequential pattern mining was applied on sequences of calculator keystrokes to obtain patterns of operations that were representative of students’ problem-solving strategies or processes. Results indicated that higher scoring students not only were more likely to use calculators, but also used them in a more goal-driven manner than lower scoring students.
A Commentary on Research Commentaries
Authors: Kilpatrick Jeremy
Published: March 2023

In May 1970, in the third issue of the Journal for Research in Mathematics Education, the JRME Editorial Board published information for prospective authors, calling for manuscripts of various types. The Board announced a new section tentatively titled “A Forum for Researchers,” manuscripts for which would be short (no more than three typed pages) and offer “analyses, critiques, or proposals about the nature of research in mathematics education.”
Transfer, Abstraction, and Context
Authors: Jones Matthew G.
Published: March 2023

In this article, I respond to the recent work of Kaminski, Sloutsky, and Heckler (2008a). I advance two major concerns about their research and its applicability to learning mathematics: a confounding variable that arises from the mathematical differences between the generic examples and concrete examples poses a threat to the construct validity of the experiments, and the overgeneralization of the success of the treatment, given that the measure of success is a prompted near-transfer task.
Developing Preservice Teachers’ Understanding of Area Through a Units Intervention
Authors: Wickstrom Megan H.
Published: March 2023

Preservice elementary teachers (PSTs) often enter their teacher preparation programs with procedural and underdeveloped understandings of area measurement and its applications. This is problematic given that area and the area model are used throughout K–Grade 12 to develop flexibility in students’ mathematical understanding and to provide them with a visual interpretation of numerical ideas. This study describes an intervention aimed at bolstering PSTs’ understanding of area and area units with respect to measurement and number and operations. Following the intervention, results indicate that PSTs had both an improved ability to solve area tiling tasks as well as increased flexibility in the strategies they implemented. The results indicate that PSTs, similar to elementary students, develop a conceptual understanding of area from the use of tangible tools and are able to leverage visualizations to make sense of multiplicative structure across different strategies.
Centering Professional Development Around the Instructional Quality Assessment Rubrics
Authors: Candela Amber G. , Boston Melissa
Published: March 2023

In this article we detail a research study using the Instructional Quality Assessment (IQA) Rubrics (Boston, 2012) as the frame for a professional development with mathematics teachers in grades 3-8. We wanted to create a professional development around a tool that was typically used in research as a way to observe teachers, as a tool to use with teachers on their reflection of instruction. In this study we share both the researchers’ and teachers’ perspectives of affordances and constraints of the professional development and observational rubrics.

Authors: Favero Marcela Bortotti , Alvarez Francisco J.S.M. Alvarez
Published: March 2023

O estudo tem o objetivo de analisar as ações das marcas de luxo de moda dentro da rede social Facebook. Para isso, baseou-se no relatório do ano de 2012 da BranZ onde identificou-se as três marcas mais valiosas do setor de luxo: Louis Vuitton, Hermès e Gucci. O trabalho foi desenvolvido por meio do monitoramento das fan pages dessas marcas. Como resultados, nota-se que não existe incentivo para os usuários iniciarem um diálogo, pressuposto básico dessa plataforma de comunicação. Por consequência, a página acaba assumindo o caráter de um catálogo virtual, já que as principais ações são os posts relacionados a divulgação de produtos e campanhas.
A máscara e os personagens mascarados nos folguedos maranhenses
Authors: Boralho Tácito Freire , Silva Rogério Vaz da
Published: March 2023

Este trabalho discorre sobre o uso da máscara como objeto estético, lúbrico, ora poético, ora contraventor, e sobre seu uso por períodos de festividades marcantes da cultura popular do Estado do Maranhão. Procura-se estabelecer uma breve investigação sobre a simbologia de tais objetos nos aspectos do riso e do grotesco. Busca-se, também, estabelecer um breve entendimento de como e quando esse objeto máscara e sua utilização nos folguedos pode ter sido considerado nocivo ou vítima de um posicionamento político retrógrado. Superando as possíveis divergências, pode ser encontrado sobejamente como integrante de composições tipológicas de personagens, a partir da construção de formatos e materiais variados e também das diferentes maneiras de vesti-lo.
Política(s) do acervo no teatro de marionetas em Portugal hoje
Authors: Zurbach Christine
Published: March 2023

O artigo descreve várias modalidades de conservação e preservação do acervo das companhias de teatro de marionetas. A partir da descrição de estudos de casos que pertencem ao repertório teatral em atividade em Portugal hoje, podemos identificar traços comuns que visam valorizar quer os espólios antigos, quer contemporâneos. A marioneta antiga ou tradicional é tratada como um objeto de memória identitária, valorizado igualmente enquanto património material e imaterial, e é salvaguardada enquanto objeto cénico e museológico. Os acervos contemporâneos são marcados por uma nova perceção da marioneta enquanto objeto estético e artístico, e são expostos ou reutilizados em atividades de extensão para a comunidade.
Les dispositions d’ordre public et les actes uniformes de l’Organisation pour l’harmonisation en Afrique du droit des affaires (OHADA)
Authors: Mbdia Balla Philibert
Published: March 2023

En conférant le caractère d’ordre public à des normes juridiques contenues dans les actes uniformes de l’Organisation pour l’harmonisation en Afrique du droit des affaires (OHADA), le législateur OHADA semble s’être éloigné de l’objectif recherché par le Traité OHADA signé le 17 octobre 1993 à Port-Louis (Ile Maurice). Selon ce dernier, les normes communes doivent être simples, modernes et adaptées aux économies dans les États parties. Cependant, au regard de l’impérativité ou de la rigidité qui caractérise l’ordre public, on pourrait se rendre compte que les dispositions d’ordre public sont incompatibles avec l’approche juridique souple préconisée pour un acte uniforme donné. Il y a donc lieu de trouver les mécanismes de rapprochement des dispositions d’ordre public avec les actes uniformes. Ce changement passerait par un aménagement du cadre d’expression des dispositions d’ordre public dans les actes uniformes, tout d’abord en procédant à la déréglementation desdites dispositions d’ordre public et, par la suite, en optant pour une nouvelle approche juridique nommée « régulation ».

Représentations du métier d’enseignant du secondaire avant et après expérience : de la transmission de savoirs à la prise en compte d’un relationnel de confiance
Authors: Chirot Patricia , Raffin Carole , Ghedir Said
Published: March 2023

Les enseignants se représentent couramment leur activité comme la possibilité de transmettre des savoirs. Une enquête récente menée auprès d’enseignants du secondaire, touchant à leurs représentations, avant d’entrer dans le métier et après expérience, montre une évolution marquée par le surgissement d’une préoccupation de préserver un relationnel enseignant-élèves satisfaisant et caractérisé par un ressenti partagé de confiance. En appui, les méthodes pédagogiques connaissent une mutation dans laquelle l’outil numérique joue un rôle majeur. Cette étude pose donc la question de la possibilité de mesurer la satisfaction d’enseigner aujourd’hui, dans la perspective du développement professionnel de l’enseignant qui se trouve face à des enjeux socio-éducatifs impensés à son entrée dans le métier. Ainsi, le sens donné à l’activité enseignante, à travers le postulat de son utilité, confère, aujourd’hui, tout son relief à l’identité métier subjectivée et serait un facteur qui, interprété comme tel, pourrait s’associer au sentiment de bonheur.
Le bien-être à l’école, une question de santé nécessaire pour s’épanouir
Authors: Loton Bidal Marie-Pierre
Published: March 2023

Le Centre national d’étude des systèmes scolaires (CNESCO) a récemment souligné la corrélation entre la qualité du vécu scolaire et la qualité des apprentissages, pointant l’importance du bien-être des élèves. Nous formulons que la bien-traitance pédagogique, définie comme l’ajustement de l’accompagnement des élèves à leurs besoins psychoaffectifs, améliore la qualité du vécu scolaire, permet l’épanouissement personnel et produit du bonheur d’être à l’école (De la Garanderie, 2013). Notre recherche-action, dans une optique de bien-être partagé, s’est intéressée au confort de travail d’élèves de cycle 3 avec la mise en place d’un dispositif expérimental dont l’objectif était de prendre soin des enfants, tout en soutenant leurs enseignants dans cette démarche, avec un accompagnement à l’accompagnement. Une charte de bien-traitance pédagogique (Loton, 2020), issue de l’univers médical et traduite en praxies professionnelles enseignantes idoines aux besoins de chacun, a permis la mise en oeuvre d’une pratique d’accompagnement pédagogique référée au bien-être. Le recueil du ressenti scolaire auprès des enfants à l’aide d’un outil créé spécifiquement pour mesurer la qualité du vécu : une Échelle de Mesure du Vécu Scolaire (Habib et Bidal, 2016) a permis d’obtenir des résultats qui révèlent l’augmentation de l’épanouissement personnel et valide la capacité du dispositif bientraitant mis en place à produire du bien-être scolaire.

Ozone: A surprising gas with multiple action for health, beauty and longevity.
Authors: Re Lamberto
Published: March 2023

Notwithstanding the use of ozone in medicine has become widespread in many countries of the world, its real pharmacological action remains not completely clarified.
We know that other than its uses as disinfectant, well documented by the literature since the beginning of the past century, the more recent medical use of ozone in several pathologies as described by the international literature is still poor investigated. Furthermore, following its clinical uses with excellent clinical responses on several heterogeneous diseases and pain, it is now clear that the biological activity of this gas is mediated by graded responses to the mild oxidative stress induced after its application. Thus, the ancestral environment of our cells, whose energy production is strictly bind to oxygen burn, may be mediated by common defenses probably linked to the ubiquitous signaling pathway mediated by Nrf2.
Moreover, after the first description of the oxidative stress in the 1970s and the discovery of Nrf2 as transcription factor in 1994, we could observe a rapid growth of the literatures regarding its function as master regulator of a myriad of cellular processes and its association to a multiple pattern of diseases including aging.
In conclusion, to my opinion, the Systems Medicine approach could finally represents the real key to better understand the wide reported efficacy of ozone treatment.
The remedy ozone for prevention and as effective method for treatment of sars.Cov-2-infection.
Authors: Thiele Renate
Published: March 2023

Due to the oxidation-sensitive cysteine groups in spikes and proteases, reactions with ozone occur which make it difficult for the spikes to enter the cell and for the protease to be activated.
There are 3 key positions where ozone therapy becomes effective:
• Virus spikes
• ACE2 cell receptor and Nrf2 (Nuclear Factor 2)
• Nf?B (Nuclear Factor Kappa B)
The earlier ozone is used the lower the viral load will be.
Other supporting effects of ozone therapy:
• Hypocoagulation
• Activation and modulation of the immune system
• Prevention and treatment of bacterial superinfections
• Increasing the depleted antioxidant potential
• Increase of blood circulation and oxygen supply
• Analgesia in case of muscle pain or joint pain
• Increase of serotonin, helpful against depressions
• Application as a “dead vaccine”
Ozone is a very important part of the therapy of SARS-Cov-2, but we should never forget of the necessary orthomolecular supplement, only in combination the maximum effect can be achieved.

Ozone therapy - present and perspective.
Authors: Marcvart Maria
Published: March 2023

This work connects extensive literature research of the last three decades on medical ozone and the personal clinical experience (more than ten years) of ozone therapy.
Classical and more recent concepts were considered: hormesis and lowdose concept, ozone action through messenger-molecules – reactive species (well-studied H?O? and 4-HNE), their implication in the redox homeostasis and in cellular signalling and the consecutive cellular response by adaptation or apoptosis. Another issue in the therapy is a correct diagnosis – based on molecular mechanisms. Many current diseases are sharing commune etiopathogenesis – redox homeostasis alteration, mitochondrial dysfunction, chronic inflammation, endothelial disturbances, early cellular senescence, accelerated apoptosis. As such, a new therapeutic concept aimed to adjust these mechanisms appeared: “Many diseases - One therapy”, and the ozone fits perfectly to this pattern.
The mentioned diseases and their complications have a tremendous emotional and social impact on the patients and their families and a negative economic effect on society. If ozone therapy is correctly applied – proper diagnosis, low/medium doses, standard and safe procedures, complementary to the specific treatment/diet of undergone conditions – it will act on numerous diseases, improving the clinical status, stimulating the healing process, practically without side effects. Despite the O3 clinical efficacy, its potential toxicity as a strong oxidant is a cause for concern. This occurs when the doctor does not correctly evaluate the oxidant status of the patient, while he is not aware of the disease etiopathogenesis and/or when he applies inadvertent ozone operational procedures. Future works, especially controlled randomized studies, are necessary to demonstrate the efficacy and safety of ozone therapy and whether these effects persist over time.
Ozone therapy, applications in surgical pathology.
Authors: Mogoș Gabriel
Published: March 2023

The paper deals with a series of cases in the field of surgical pathology, surgically and non-surgically solved in the first private clinic with continuous hospitalisation in Oltenia region.

THE RELATIONSHIP BETWEEN SURGERY AND OZONE THERAPY.
The benefits are particularly seen in the postoperative period. A special category is wounds, as follows:
A) Chronic, non-healing, refractory to conventional treatments or special dressings.
- Local causes: resistant germs, circulatory disorders.
- General causes: diabetes, neoplasia, immunosuppressed patients.
B) Infected ulcerated mammary neoplasms
C) Postoperative infiltration, before reaching the stage of suppuration
D) Speeding up wound healing with high substance deficiency
E) Post-operative wounds defectively healed
A retrospective study conducted on 55 patients with various surgical pathologies treated with ozone for 20-40 days demonstrates the positive effect of the treatment, with an obvious improvement of symptoms and accelerated healing of postoperative wounds.
The paper will detail cases with certain particularities: age, patient’s medical background, lesion itself, evolution under treatment.
This work should awaken and propel medical specialists to reconsider ozone therapy more carefully.

The object of the study is transnational corporations. That is, companies that operate and have legal entities in various jurisdictions, which allows them to transfer the corporate tax base – profit to jurisdictions with minimal corporate tax. The transfer is carried out through the use of intra-group transfer prices. The subject of the study is current trends, ideas and international efforts in the taxation of multinational corporations. Both such trends themselves were investigated, and a computational experiment was conducted to assess the applicability of a possible methodology for calculating the profit tax of a subsidiary of such a corporation in Russia and the possible consequences for the budget from its application. The main conclusions of the study are as follows: at present, an international consensus is gradually being formed that the total profit of a transnational corporation should be distributed in a reasonable and fair way among the countries of its activities, an understanding of the need to consolidate such an order at the international level is being formed; however, no single understanding of approaches to taxation of transnational corporations, nor a single methodology capable of implementing them in practice. The scientific novelty is the author's reduction of the principle of tax neutrality from the classical principle of tax neutrality. In addition, the contribution of the authors is to demonstrate the fundamental efficiency of one of these methods by the example of calculating indicators based on open reporting data of a particular organization, as well as the consequences of using such a methodology for the budget.

Published: March 2023

The object of research is emotional tension. The subject of the study is assessment of emotional tension in the process of presentation of emotionally significant stimuli in the form of images and sounds according to the parameters of physiological activity and tensotremorometry in the process of maintaining isometric effort. Particular attention is paid to the consideration of methods of determination of tremor and its connection with emotional tension. Key aspects are the consideration of the key frequency range of physiological tremor analysis 8-16 hertz, methods of tremor measurement such as accelerometry, tensotremorometry, electromyography. Studies of the relationship between tensotremorometry on the frequency range of physiological tremor and emotional tension are considered. We propose a new method for analyzing tremor according to tensotremorometry data using the sliding window method and filtering the frequencies characteristic of physiological tremor. Methods of recording physiological activity in the form of photoplethysmography and skin electrical activity were used for reliability of the results obtained. We described and confirmed the connection between emotional tension during the demonstration of meaningful stimuli and finger tremor, while holding a given force in an isometric condition. The new technique has wide possibilities for use in the psychological and clinical fields, in particular, in detection of hidden information, assessment of the stress resistance of personnel, and determination of the functional state of a person, as well as in the study of the psycho-emotional state of students.

SECURING CENTRALIZED SDN CONTROL WITH DISTRIBUTED BLOCKCHAIN TECHNOLOGY
Authors: Ahmad Suhail , Mir Ajaz Hussain
Published: March 2023

Software Defined Networks (SDN) advocates segregation of network control logic, forwarding functions and management applications into different planes to achieve network programmability, automated and dynamic flow control in next generation networks. It promotes deployment of novel and augmented network management functions to have flexible, robust, scalable and cost-effective network deployments. All these features introduce new research challenges and require secure communication protocols among the segregated network planes. This manuscript focuses on the security issue of southbound interface which operates between the SDN control and data plane. We have highlighted the security threats associated with an unprotected southbound interface and the issues related with the existing TLS based security solution. A lightweight blockchain based decentralized security solution is proposed for southbound interface to secure the resources of logically centralized SDN controllers and distributed forwarding devices from opponents. The proposed mechanism can operate in multi-domain SDN deployment and can be used with wide range of network controllers and data plane devices. In addition to it, the proposed security solution is analyzed in terms of security features, communication and reauthentication overhead.
APPLYING HUNGER GAME SEARCH (HGS) FOR SELECTING SIGNIFICANT BLOOD INDICATORS FOR EARLY PREDICTION OF ICU COVID-19 SEVERITY
Authors: Sayed Safynaz , ElKorany Abeer , Sayed Sabah
Published: March 2023

Millions of people around the world have been affected and some have died during the global pandemic Corona (COVID-19). This pandemic has created a global threat to people's lives and medical systems. The constraints of hospital resources and the pressures on healthcare workers during this period are among the reasons for wrong decisions and medical deterioration. Anticipating severe patients is an urgent matter of resource consumption by prioritizing patients at high risk to save their lives. This paper introduces an early prognostic model to predict the severity of patients and detect the most significant features based on clinical blood data. The proposed model predicts ICU severity within the first 2 hours of hospital admission, seeks to assist clinicians in decision-making and facilitates efficient use of hospital resources. The Hunger Game Search (HGS) meta-heuristic algorithm and the SVM are hybridized for building the proposed prediction model. Furthermore, they have been used for selecting the most informative features from the blood test data. Experiments have shown that using HGS for selecting the features with the SVM classifier achieved excellent results compared with the other four meta-heuristic algorithms. The model using the features selected by the HGS algorithm accomplished the topmost results, 98.6% and 96.5% for the best and mean accuracy, respectively, compared with using all features and features selected by other popular optimization algorithms.

Paclitaxel (Taxol) is a taxane and a chemotherapeutic drug that stabilizes microtubules. While the interaction of paclitaxel with microtubules is well described, the lack of high-resolution structural information on a tubulin-taxane complex precludes a comprehensive description of the binding determinants that affect its mechanism of action. Here, we solved the crystal structure of baccatin III the core moiety of paclitaxel-tubulin complex at 1.9 Å resolution. Based on this information, we engineered taxanes with modified C13 side chains, solved their crystal structures in complex with tubulin, and analyzed their effects on microtubules (X-ray fiber diffraction), along with those of paclitaxel, docetaxel, and baccatin III. Further comparison of high-resolution structures and microtubules’ diffractions with the apo forms and molecular dynamics approaches allowed us to understand the consequences of taxane binding to tubulin in solution and under assembled conditions. The results sheds light on three main mechanistic questions: (1) taxanes bind better to microtubules than to tubulin because tubulin assembly is linked to a βM-loopconformational reorganization (otherwise occludes the access to the taxane site) and, bulky C13 side chains preferentially recognize the assembled conformational state; (2) the occupancy of the taxane site has no influence on the straightness of tubulin protofilaments and; (3) longitudinal expansion of the microtubule lattices arises from the accommodation of the taxane core within the site, a process that is no related to the microtubule stabilization (baccatin III is biochemically inactive). In conclusion, our combined experimental and computational approach allowed us to describe the tubulin-taxane interaction in atomic detail and assess the structural determinants for binding.
Clinical Outcomes of Transcatheter Arterial Embolization after Failed Endoscopic Intervention for Acute Non-Variceal Bleeding Associated with Benign Upper Gastrointestinal Diseases

Published: March 2023

Background/Aims: Transcatheter arterial embolization (TAE) is useful for management of uncontrolled upper gastrointestinal (UGI) bleeding. We investigated clinical outcomes of TAE for non-variceal bleeding from benign UGI diseases uncontrolled with endoscopic intervention.Methods: This retrospective study performed between 2017 and 2021 across four South Korean hospitals. Ninety-two patients (72 men, 20 women) who underwent angiography were included after the failure of endoscopic intervention for benign UGI disease- induced acute non-variceal bleeding. We investigated the factors associated with endoscopic hemostasis failure, the technical success rate of TAE, and post-TAE 30-day rebleeding and mortality rates.Results: The stomach (52/92, 56.5%) and duodenum (40/92, 43.5%) were the most common sites of bleeding. Failure of endoscopic procedures was attributable to peptic ulcer disease (81/92, 88.0%), followed by pseudo-aneurysm (5/92, 5.4%), and angiodysplasia (2/92, 2.2%). Massive bleeding that interfered with optimal visualization of the endoscopic field was the most common indication for TAE both in the stomach (22/52, 42.3%) and duodenum (14/40, 35.0%). Targeted TAE, empirical TAE, and exclusive arteriography were performed in 77 (83.7%), nine (9.8%), and six patients (6.5%), respectively. The technical success rate, the post-TAE 30-day rebleeding rate, and the overall mortality rate were 100%, 22.1%, and 5.8%, respectively. On multivariate analysis, coagulopathy (OR, 5.66; 95% CI, 1.71~18.74; P=0.005) and empirical embolization (OR, 5.71; 95% CI, 1.14~28.65; P=0.034) were independent risk factors for post-TAE 30-day rebleeding episodes.Conclusions: TAE may be useful for acute non-variceal UGI bleeding. Targeted embolization and correction of coagulopathy can improve clinical outcomes.
A new deep learning-based technique for rice pest detection using remote sensing
Authors: Hassan Syeda Iqra , Alam Muhammad Mansoor , Illahi Usman , Mohd Suud Mazliham
Published: March 2023

Background

Agriculture plays a vital role in the country’s economy and human society. Rice production is mainly focused on financial improvements as it is demanding worldwide. Protecting the rice field from pests during seedling and after production is becoming a challenging research problem. Identifying the pest at the right time is crucial so that the measures to prevent rice crops from pests can be taken by considering its stage. In this article, a new deep learning-based pest detection model is proposed. The proposed system can detect two types of rice pests (stem borer and Hispa) using an unmanned aerial vehicle (UAV).

Methodology

The image is captured in real time by a camera mounted on the UAV and then processed by filtering, labeling, and segmentation-based technique of color thresholding to convert the image into greyscale for extracting the region of interest. This article provides a rice pests dataset and a comparative analysis of existing pre-trained models. The proposed approach YO-CNN recommended in this study considers the results of the previous model because a smaller network was regarded to be better than a bigger one. Using additional layers has the advantage of preventing memorization, and it provides more precise results than existing techniques.

Results

The main contribution of the research is implementing a new modified deep learning model named Yolo-convolution neural network (YO-CNN) to obtain a precise output of up to 0.980 accuracies. It can be used to reduce rice wastage during production by monitoring the pests regularly. This technique can be used further for target spraying that saves applicators (fertilizer water and pesticide) and reduces the adverse effect of improper use of applicators on the environment and human beings.
Bidirectional matching and aggregation network for few-shot relation extraction
Authors: Wei Zhongcheng , Guo Wenjie , Zhang Yunping , Zhang Jieying , Zhao Jijun
Published: March 2023

Few-shot relation extraction is used to solve the problem of long tail distribution of data by matching between query instances and support instances. Existing methods focus only on the single direction process of matching, ignoring the symmetry of the data in the process. To address this issue, we propose the bidirectional matching and aggregation network (BMAN), which is particularly powerful when the training data is symmetrical. This model not only tries to extract relations for query instances, but also seeks relational prototypes about the query instances to validate the feature representation of the support set. Moreover, to avoid overfitting in bidirectional matching, the data enhancement method was designed to scale up the number of instances while maintaining the scope of the instance relation class. Extensive experiments on FewRel and FewRel2.0 public datasets are conducted and evaluate the effectiveness of BMAN.
Six new species of free-living nematodes (Nematoda: Enoplida) from deep-sea cold seeps on Hikurangi Margin, New Zealand
Authors: Leduc Daniel
Published: March 2023

Little is known about the taxonomy of deep-sea nematode species inhabiting cold seep habitats. An opportunity to characterize the nematode species communities of New Zealand cold seeps was provided by a 2019 research voyage to New Zealand’s Hikurangi Margin, during which macrofauna cores were obtained at two seeps at approximately 1,250 and 2,000 m water depth. Here, six new species of the orderEnoplida are described. Metacylicolaimus catherinae sp. nov. represents the first record of the genus for the New Zealand Exclusive Economic Zone and for the deep sea globally. Halalaimus talaurinus sp. nov., Thalassoalaimus duoporus sp. nov. and Crenopharynx crassipapilla sp. nov. are only the second species of their respective genera to be described/recorded from New Zealand waters, and Oncholaimus adustus sp. nov. is the eighth species of the genus to be recorded from the region. Rhabdodemania zealandiaensis sp. nov. was among the most abundant and widespread species found at the Hikurangi Margin seep sites. A few specimens had been found in a previous ecological study of meiofaunal nematode communities on Chatham Rise, a submarine ridge south of Hikurangi Margin. It is possible that this species has a preference for seep environments due to elevated food availability, however it does not seem to be exclusively found in seeps. We find no evidence for an affinity between nematode seep communities in New Zealand and elsewhere, which is consistent with the high variability in nematode community observed to date among regions. Ongoing work on the ecology and distribution of nematode communities at the Hikurangi Margin seep sites will help determine spatial patterns in abundance and species distributions in more detail, including the identification of any species/taxa with affinities with seeps.

The highest NH3volatilization losses were observed in T2at about 20.4 kg ha−1per season. Significant reduction in NH3volatilization losses were observed in T3by 40%,T4by 27%, and T8by 17% when compared to the control treatment. Soil urease activity was found to be decreased in plots receiving amendments, T3, T4, and T5. The highest grain yield was observed in the T7treated plot with 5.09 t ha−1,and straw yield of 9.44 t ha−1in T4.

Conclusion

The shifting towards organic amendments is a feasible option to reduce NH3volatilization from wheat cultivation and improves NUE.

Introduction: Non surgical periodontal therapy by scaling is done by using different sets of hand and motor driven instruments. The best instrument for non surgical periodontal therapy has to be identified, so that, it will benefit the clinicians in point of ergonomics and for patients in terms of less discomfort caused during scaling. Aim: To compare the effectiveness of Linear Monolithic (LM) instruments to Hu-Friedy instruments in non surgical periodontal treatment. Materials and Methods: The split-mouth randomised clinical trial study comprised 50 patients, who were selected from those attending the Department of Periodontics and Implantology, Vishnu Dental College, Bhimavaram, Andhra Pradesh, India, and who were classified with gingivitis or moderate to severe periodontitis according to American Academy of Periodontology (AAP) standards from 1999 and had not undergone any periodontal therapy in the previous six months to one year. The study was conducted from September 2021 to February 2022. Periodontal treatment outcomes were evaluated by plaque index, bleeding index, probing pocket depths, gingival index, and clinical attachment level. Clinicians comfort levels and handling characteristics of two sets of hand instruments (Test: LM instruments to control: Hu-Friedy instruments) were assessed by questionnaire consisting of 10 closed ended questions immediately after the non surgical therapy. The unpaired t-test was used for intergroup analysis and one-way ANOVA was used for intragroup analysis. Results: The mean gingival index scores for test and control sites at baseline were (1.65 and 1.72), at one week were (0.89 and 0.64) and at one month were (0.46 and 0.31). The mean periodontal pocket depth for test and control sites at baseline were (3.93 and 3.79), at one week were (3.40 and 3.25) and at one month were (3.18 and 2.42). A statistically significant difference seen in gingival index (p=0.001), sulcus bleeding index (p<0.001), periodontal probing depths (p<0.001) and clinical attachment level (p<0.001) at one-month interval. Conclusion: The findings demonstrate that LM instruments have higher handling features and cutting efficiency than HuFriedy instruments, althou gh there is no significant difference in plaque index, gingival index, probing depth reduction, sulcus bleeding index, or clinical attachment level.

Published: March 2023

The study was conducted to identify the problems faced by Scheduled Caste co-operative societies and their members in Thrissur district. Participatory Rural Appraisal method was employed to collect information from the respondents. Five SC co-operative societies were identified from the district and ten individuals from each society, consisting of five members and five directors, were selected for the study, thus making a total of 50 respondents. Major problems faced by the societies and their members were identified. The study highlights the issues faced by the SC community and shows the need to ensure that the benefits reach the actual beneficiaries.  Necessary steps should be taken to increase member participation in the societies. Recruitment policies may be framed accordingly for efficient human resources. Future studies can be undertaken to evaluate the performance of these societies and examine the factors influencing member participation.

The Weibull-inverse exponential-loglogistic distribution which is abbreviated as (Weibull-IE-loglogistc) is a member of the neotric T- inverse exponential family introduced previously by the authors. Properties of this distribution such as (mode, quantile function, median, hazard function, survival function, moments, order statistics and Shannon’s entropy) are derived, and maximum likelihood estimates of its parameters are obtained. The usefulness of this neoteric distribution in analyzing data is illustrated. A simulation study is conducted to evaluate the performance of this distribution.
Chronic and Stubborn Leuco-melanoderma in a Child: A Case Study

Aims: Pityriasis lichenoides chronic is a rare inflammatory dermatosis, unusually hypochromic in dark phototypes. The evolution of the disease is usually benign, but a malignant transformation in mycosis fungoides is reported. You have to know how to think about it when faced with a generalized hypochromic macular eruption in children.

Case Report: We report a case of a 13-years-old child, photo type 4.He presented for 8 months hypochromic macular lesions, located initially at the face. The evolution was marked by the extension at the trunk and the limbs. He was treated for pityriasis versicolor but without improvement. A skin biopsy was then performed, in favor of Pityriasis Lichenoides Chronica (PLC) with a lymphoid infiltrate made up mainly of CD4 T lymphocytes. The child was put on cyclin associated with heliotherapy with a moderate improvement after 3 months of treatment. The patient was followed for 2 years during which he did not present any malignant transformation.

Discussion: Pityriasis Lichenoides is less frequent in the pediatric population.Its etiopathogenesis is still incompletely elucidated. The basic lesion is an erythematous-squamous papule in the trunk. Hypochromic macules can also be observed, either at the cicatricial stage of the disease, or they occur immediately, especially in subjects with dark skin. The histology of PLC reveals perivascular lymphocytic infiltrate in the superficial dermis..The adopted therapeutic is based on heliotherapy or an antibiotic from the macrolide or cyclin family. Evolution towards Mycosis Fungoides has been rarely described.

Conclusion:  PLC is exceptionally hypopigmented from the outset. We report a case of chronic leucomelanodermic pityriasis lichenoides in a child posing a problem of differential diagnosis.

The change in air temperature will influence the insect behavior, physiology and population dynamics of insects as they are poikilothermic. Global temperature has increased by 1.09°C during 2001-2020 when compared to 1850-1900. It is projected that the temperature will further increase by 5.7°C under high emission scenario, if mitigation strategies are not adopted. Increase in temperature would affect the physiology and population dynamics of the insects. A study was undertaken to understand the effect of different temperature regimes on rice leaffolder. Survival fraction decreased with increasing temperatures as more successful development was at lower temperature regimes. Apparent mortality increased towards the higher temperature regimes as the insects cannot tolerate high temperature stress. The Mortality Survivor Ratio (MSR) revealed that the population increase would be more at higher temperature regimes as the MSR remained higher at higher temperature regimes. The Indispensable Mortality was lesser under higher temperature regimes as the number of adults emerged in the high temperature regime was less. Generally, K - values increased with increasing temperature. It indicates that the insects which happened to live under higher temperature regimes were reproduction oriented as most of the energy was spent in reproduction rather than for living longer time.

E-resources are now an essential part of all intellectual activities in higher education. Realizing the value of e-resources, the majority of Indian colleges have made generous investments to give students access to these materials to assist learning, teaching, and resources. Every country's finest learning and intellectual centres are universities, and university libraries are what fuel all of these centres' intellectual pursuits. The present study aims to study on attitude of students (Post-Graduate and Ph.D level) about e-resources in Academic and Research work of agriculture universities of Uttar Pradesh. The study was conducted during 2022 in the state using a structured questionnaire and data were collected through Online Google Form. About 240 responses were received and analysed. Out of total respondents’ 26 percent were females while 74 percent were males, 23-29 years of age (57.50%) and 46% belonged to rural background. To measure the attitude of students towards e-resources, the scale was developed by the investigator for data collection from the students. Majority of the students had medium level of attitude. Students from four agriculture universities, had more or less similar attitude towards e-resources which might be due to more or less same awareness about various e-resources available in their universities. It was found that most of the students strongly agreed with the fact that “e-resources are useful to update the knowledge globally” with 92 MPS. Students of agriculture universities had a positive and favourable attitude towards e-resources but required proper exposure and training at the right time for the better utilization of all e-resources.
