Groundnut (Arachis hypogaea L.) is an important oil seed crop mainly grown as rainfed crop. Due to erratic rainfall and frequent drought during the crop growth period, groundnut yields are generally low and unstable under rainfed conditions. Drought during critical crop growth stages is crucial for yield in groundnut varieties. But tolerant genotypes may give better yield due to maintenance of physiological responses that were triggered during drought. The experiment was conducted in the Department of Crop Physiology, Tamil Nadu Agricultural University, Coimbatore during 2015-2016 to study physiological characters responsible for improving yield of different groundnut genotypes viz., CO 7, COGn 4, TMV 7 and TMVGn 13 under water stress at different flowering phases viz., pre flowering drought (PFD) during 15- 30 DAS, flowering drought (FD) during 35-50 DAS and post flowering drought (PoFD) during 75-90 DAS by withholding irrigation and control was also maintained with watering up to field capacity for comparison. Observations on various physiological parameters viz., leaf area, root length, relative water content, osmotic potential and leaf gas exchange parameters including, photosynthetic rate, transpiration rate and stomatal conductance were studied during stress and recovery period. Among the treatments, the plants under PFD performed better in recording higher value of physiological parameters under stress and recovered quickly. The variety, CO7 was found to perform well under all stages of stress followed by TMV 7, TMVGn 13 and COGn 4 with respect to physiological parameters and yield.

Published: May 2023

The context for this study was to document fishers’ experience-based knowledge is reliable and can be included in citizen science as supplementary information to scientific research. Fishers’ experience-based knowledge contributes to important understanding of the environment and the marine ecosystem. Hence, fishers’ knowledge over time is not always regarded as supplementary knowledge. There is a lack of information on how fishers have acquired reliable knowledge when they have not had formal scientific education and in what way fishers’ knowledge can be used as empirical data. In this study, a survey was conducted by scientific educator within the fishing community of Mausund in Norway. The survey was limited to specifically targeting fishers' knowledge of the migration pattern of the edible crab (Cancer pagurus) in Sulfjorden, Mausund and Frohavet. This study performs in-depth interviews with five fishers at Mausund. The experience-based knowledge acquired by these fishers is first and foremost learnt through intergenerational learning from fathers, grandfathers, and uncles to sons. The study supports existing research on fishers’ experience-based knowledge, which is professional and very precise. Experience-based and local knowledge can be understood as a knowledge contribution of value to the research field of environment monitoring.

Authors: DAĞLIOĞLU Selim , BEKTAŞ Uğur Emre
Published: May 2023

According to the ILO Convention No. 102, family benefits are a social security branch established to compensate for the increase in the expenditure of those protected due to the expenses necessary for the care of the children, they are responsible for, and to protect the level of life they have reached before the child's existence. Nevertheless, family benefits can make contributions in many such areas as increasing the fertility and population of the country, reducing poverty, preventing child poverty, extending the country's welfare level to the whole society, and raising physically and mentally healthier individuals. In this respect, countries develop various practices of family benefits depending on their social policies and welfare levels. Demographic structures and economic development levels of countries are generally taken into account in determining family benefits. Minimum standards of family benefits may be higher in economically developed countries. In this study, current practices in EU member countries are examined on the basis of minimum standards of family benefits under the Convention No. 102 and a comparative analysis of these practices is presented. As a result of the study, it has been determined that there is a child benefit application, which is a periodic payment aid, in all EU member states although there is no obligation to make periodic payments within the scope of family benefits in the Convention No. 102. In addition, it has been observed that many types of family benefits that can contribute to goals such as increasing birth rates and encouraging parents, especially women, to stay in employment are widely applied in EU member states.

BARRAGENS DE MARIANA E BRUMADINHO E PREÇO DA AÇÃO DA VALE: UM ESTUDO DE EVENTO
Authors: Rocha Carlos Henrique , Vasconcelos José Guilherme
Published: May 2023

A Samarco subsidiária da Vale S.A. e de uma mineradora australiana mantinha em Mariana e Brumadinho, em Minas Gerais, barragens de rejeitos de mineração. O objetivo da barragem é impedir que os resíduos tóxicos não cheguem aos rios e córregos da região. A barragem de Mariana se rompeu em 5 de novembro de 2015 e a de Brumadinho em 25 de janeiro de 2019. Vidas se perderam, rios e córregos foram contaminados e lamas tóxicas se alastraram por quilômetros de terras. O Brasil assistiu a dois acidentes com barragens de rejeitos de mineração jamais vistos. Os rompimentos das barragens afetaram o preço das ações da Vale? Por meio da abordagem financeira conhecida por estudo de evento concluiu-se que o rompimento da barragem de Fundão, de Mariana, provocou uma queda acumulada pós-evento estatisticamente significante no preço da ação da mineradora. Já a ruptura da barragem do Córrego do Feijão, de Brumadinho, afetou o preço da ação da Vale somente no dia do acidente, sem repercussões no resto do pós-evento. Presume-se que os investidores da Vale rapidamente precificaram os danos causados pelo rompimento da barragem de Brumadinho no valor da sua ação.

A key moment in the history of mankind has been urbanization, and there is no doubt that the world is rapidly urbanizing, which is causing temperature changes. The relationship between climate change and rapid urbanization in Nguru Local Government Area, Yobe State, Nigeria, is investigated in this paper. The study used remote sensing data to reveal the extent of urban microclimate change trends over the next two decades (2001–2021). Thus, the microclimate temperature increased by nearly +5.32 °C in 2021 (39.39°C) compared to 34.07°C in 2001. Furthermore, the minimum temperature in 2001 was 22.33 °C, while that of 2021 was 23.36 ℃. The built-up area increased by 556.73%, from 446 hectares in 2001 to 2,483 hectares in 2021. Accelerated urbanization and the city's blue and green facilities, which are not preserved or safeguarded due to a poor planning system, are to blame for these modifications to the urban climate and design. The study aimed to determine the relationship between urbanization and urban heat islands in Nguru local government area, Yobe State, Nigeria. The picture of the situation in Nguru sheds light on the enormous challenges that cities in developing countries encounter in dealing with local and global climate change-related risks. Indeed, this situation necessitates an integrated strategy to address climate change both within and outside of cities. Policymakers must increase spending on urban planning, fund, adaptation of approaches through urban planning, and strengthen urban planning institutions.

The verification has been done by using MATLAB and Simulink software.
The Leaching Behavior of Zinc Oxide in Medical Waste of Dental Clinics
Authors: Jebur Saja M. , Kareem Jathwa A.
Published: May 2023

Zinc Oxide is an indispensable substance in the field of dental treatment. It is used daily and intensively in all governmental and private dental clinics, leading to the disposal of very high concentrations of zinc with waste and eventually in landfill sites as a final destination for solid waste removal. This indicates the urgent need to investigate its behavior upon disposal due to the surrounding conditions. Approximately 4195 g of mixed dental waste samples were collected from (17) healthcare centers in Baghdad Al-Karkh. The leaching behavior of ZnO powder was investigated through batch reactors using makeup dental solid waste samples. The ZnO leaching was tested with 3 conditions; acidic, alkaline, and Ionic Strength (IS). The acidic condition was considered the most hazardous condition compared with basic and salinity due to the increasing tendency of ZnO to release Zn ion within waste leachate. In solutions with low pH, the dissolution of ZnO tends to produce zinc ions due to the attack of the ZnO surface by proton. In solutions of pH more than 9, the degradation of zinc oxide produces hydroxide complexes. Increasing (IS) decreased zinc concentration in leachate samples with time by promoting solids aggregation, decreasing the repulsive forces of ZnO particles, and accumulating in the bottom of reactors.

Introduction. Women's attitudes to money seem to play an important role in easing social tension and, therefore, need to be studied. Social transformations and the war in Ukraine, as well as global socio-political and economic crises have a powerful effect on the mentality of the individual including the economic behavior of women, which calls for researching the types of womens' money attitudes and behaviors and their relationship with socio-demographic, socio-economic and organizational-professional factors. Aim: to analyze the levels and types of womens' money beliefs and behaviors and their relationship with socio-demographic, socio-economic and organizational-professional factors. Methods. A. Fernem Money Beliefs and Behavior Scale (MBBS) (a modified version: M. Simkiv Money Perceptions and Behavior Scale (ShGUP) (Simkiv, 2012)) and a specially developed passport questionnaire. Results. Womens' money beliefs and money behaviors were divided into four groups (money obsession, power, economy, and inappropriate money behavior) and had high, medium, and low levels. Besides, womens' money beliefs and money behaviors had positive and negative statistically significant relationships with socio-demographic, socio-economic, and organizational-professional factors. Conclusions. The obtained findings suggest the need of special psychology of money training programs to increase women's monetary literacy.

Formulation of the problem. Analysis of the issue of including the topic "The simplest functional equations" in the model curricula for studying the subject "Algebra and the beginnings of analysis" for specialized classes with in-depth study of mathematics. A model curriculum studies the approximate sequence of achieving the expected learning outcomes, the content of the subject or integrated course, and the types of students’ educational activities. The inclusion of this topic aims to start a creative understanding of functional relationships existing in real systems and processes, in particular, ecological, economic, and social ones.
Materials and methods. Theoretical method of analysis of methodical and educational literature on the researched issue; comparative analysis to understand different views on the problem; systematization and generalization to create recommendations for the content of the proposed topic, as well as formulating conclusions and integrating the pedagogical experience of authors who teach relevant disciplines in educational institutions of various levels.
Results. The possible content of the topic "The simplest functional equations" in the model programs for studying the subject "Algebra and the beginnings of analysis", examples for an explanation by the teacher, and confirmation by students are proposed. For some examples, different approaches to their solution are proposed; convenient tables are provided for students to find partial solutions to some types of functional equations.
Conclusions. The authors believe that the topic "The simplest functional equations" will be useful and acceptable for studying within the scope of the subject "Algebra and the beginnings of analysis" by students of specialized classes with an in-depth study of mathematics. Within the eleven-year school education, of course, it was impossible to find time to study this topic due to the saturation and density of the material necessary for study. But in the twelve-year New Ukrainian School, marked by a deeper differentiation of specialized education, the topic "The simplest functional equations" can strengthen the fundamentality of mathematical education in classes with in-depth study of mathematics, computer science, etc. Further research in this direction may concern the method of solving the simplest recurrent equations.

Формулювання проблеми. Однією із ключових компетентностей учнів, формування якої передбачено низкою нормативних документів, є інформаційно-цифрова компетентність, що відображено у Концепції нової Української школи та навчальних програмах з фізики і природничих наук. Однак, у Державному стандарті базової середньої освіти йдеться про формування у здобувачів освіти компетентності в галузі ІКТ, окресленої терміном «інформаційно-комунікаційна компетентність». підхід.
Матеріали і методи. Використано теоретичні (аналіз наукових джерел та нормативних документів у контексті дефініцій інформаційно-комунікаційної та інформаційно-цифрової компетентностей) та емпіричні (бесіди і праксиметрія) методи дослідження.
Результати. Визначено сутність, структуру, особливості, моделі формування та співвідношення інформаційно-комунікаційної та інформаційно-цифрової компетентностей у процесі вивчення фізики в середній загальноосвітній школі, що сприятиме конкретизації цих понять і, зокрема, буде корисним для планування і формування освітянами змісту робочих документів, в основу яких покладено компетентнісний підхід. Проведено аналіз вітчизняних і закордонних наукових даних щодо досліджуваної проблеми. З’ясовано, що з широким впровадженням цифрових технологій у навчальний процес поняття інформаційно-цифрової компетентності замістило поняття інформаційно-комунікаційної компетентності, що відображено в контенті практичних освітніх документів.  Виокремлено  характерні особливості та основні компоненти інформаційно-цифрової компетентності здобувачів базової середньої освіти: інформаційна й медіа грамотність, знання про безпеку роботи в інтернеті та кібербезпеку, уміння створювати цифровий контент, уміння розв’язувати проблеми, навчальні ресурси.
Висновки. Формування інформаційно-цифрової компетентності вимагає навичок критичного мислення, дотримання правил поведінки та безпеки в інтернет-середовищі, розуміння загальних соціальних проблем, створених цифровими технологіями, уміння застосовувати інформаційні ресурси в освітній діяльності. Відтак формування інформаційно-цифрової компетентності у природничій освіті повинно здійснюватися із широким залученням навчально- дослідницької діяльності учнів, зокрема – з використанням цифрового цифрового навчального лабораторного обладнання, віртуальних лабораторій, застосуванням STE(А)M підходу до формування навчальних планів, технології m-Learning тощо.
