An overview on the microstructure and mechanical properties of sintered aluminum-based composites
Authors: Chintada Shoba , Dora Siva Prasad , Kare Dorathi
Published: March 2022

Sintered composites have revolutionized as a thermal treatment to consolidate a wide range of engineering materials where the transition of powders takes place thermally in a thermodynamical equilibrium state with a decrease in free surface energy in materials owing to their specific capability. Sintering aids in providing effective bonding between the reinforced powder particles. However, the inadequate understanding of the sintering mechanism may limit the practical application of a few materials such as aluminum metal matrix composites. In addition to the rapid growth of various sintering related technologies, researchers need attention to highlight the structural barriers and forecast the emerging demands while dealing with such composites. A review report is made in this paper regarding the sintering mechanisms and sintering techniques. Common sintering techniques such as traditional, microwave assisted, hot pressing, hot isostatic sintering, and spark plasma sintering are identified and discussed here. As a result, the key challenges in sintering aluminium metal matrix composites that can affect sintering parameters are investigated. From the review, spark plasma is identified to attain densified and pore-free green composites and, microwave sintering is the best technique for achieving uniform microstructure in powder metallurgy samples.

Published: March 2022

In modern times, the demand for natural fibers is increased due to low density, low cost, recyclability, and biodegradable properties. Following work deals with the aquatic waste of water hyacinth plant fiber. The main intent of this work is to utilize the hyacinth plant into a successive manner and convert this plant into some commercial products. It is used as reinforcement material and epoxy polymer resin in matrix material with a suitable percentage of hardener (10:1). A new method such as a mechanical way of extraction process is introduced in this work. The different weight percentage of the hyacinth fiber is reinforced with matrix material like 15, 20, 25, 30, and 35%. With the help of a compression molding, machine water hyacinth reinforced fiber composite is produced by using 1500 PSI pressure and 110 °C, 100 °C of upper and lower plate temperature. A composite sample is cut into as per ASTM standards and the mechanical tests like tensile, flexural, impact test is conducted by using universal testing machine (UTM), and Charpy impact test machine. Based on the final mechanical test results, the 30% of hyacinth composite sample tensile 36.48 MPa, flexural 48.62 MPa, impact 0.5 J, and hardness 98 attained then, the hyacinth composite samples are adopted into water and chemical absorption test with 10 hours, 1week, 1month of continuous monitoring. Based on the final results, hyacinth fiber is strongly recommended to use an alternative of synthetic fibers and conventional natural fibers. The hyacinth composite is strongly recommended for the usage of commercial and household applications.

Authors: Vuddagiri Hari Kiran , Rallabandi Sivasankara Raju , Vadapalli Srinivas , Pandi Thimothy
Published: March 2022

This work emphasizes the mechanical and tribological performance of Al-Si/Al2O3/MoS2 hybrid matrix composites. The composites are reinforced by varying weight percentages of Al2O3 (8%, 12%, and 16%) and MoS2 (0%, 2%, and 4%), and were prepared by stir casting. As the weight percentage of Al2O3 in a composite grows, so does its hardness and tensile strength. The addition of 2% wt. MoS2 enhances the specific strength and tribological properties, according to the research. However, when compared to other composites studied, the Al/16% Al2O3 composite had improved mechanical properties. MoS2 also aids the hybrid composite in achieving higher tribological characteristics while marginally lowering the specific strength. Taguchi orthogonal array (L27) is used to design tribological performances with process parameters viz. applied load, sliding speed and weight % of Al2O3 as well the percentage of MoS2 whereas wear rate (mm3/m), wear (µm) and coefficient of friction were considered as the responses. A hybrid Grey–Fuzzy Reasoning Approach (GFRA) is used to optimize a multi-response for avoiding vagueness in decision making. The statistical analysis revealed that Al/2%MoS2/16%Al2O3 composite has exhibited better wear resistance than other composites. The confirmation test is also conducted to validate the optimal condition obtained by ANOVA.

Authors: Pramod Kumar  , Shanker jha  , NN Ray Sanjeev Singhal
Published: March 2022

Heavy metal pollution, in the aquatic ecosystem, has become an area of concern garnering increasing attention since the past few decades. These metals are introduced into the marine ecosystem mainly due to anthropogenic activities including offshore Oil and Gas exploration and production activities Though rich in aliphatic and aromatic hydrocarbons, crude oil also contains some trace element like vanadium, nickel, iron, aluminium, copper and some heavy metals like lead and cadmium. Poisonous or hazardous components of crude oil are mainly benzene and heavy metals which vary depending on the source of the crude oil. Elements like copper, mercury, lead, cadmium, zinc and chromium are very toxic. Except copper and zinc, others are nonessential and toxic. In fact, all metals are toxic at high concentrations. The heavy metal overload has inhibitory effects on the development of aquatic organisms such as phytoplankton, zooplankton, and fish. The metallic compounds could disturb the oxygen level and mollusc’s development, byssus formation, as well as reproductive processes. Hence, monitoring the heavy metal concentrations in sea water over a period of time is of great help in checking the pollution level and identifying the trend, which in turn will be instrumental in formulating sustainable practices. The paper mainly focuses on the study of the concentration of non-essential heavy metals in sea water around the operational areas of ONGC in western offshore area. The distribution of heavy metals in the seawater of ONGC’s exploratory blocks in Krishna-Godavari Basin, Bay of Bengal was investigated. Fifty four sea water samples collected as per OSPAR guidelines from each blocks (Vasihta G1 PML-65, Yaman PML, Godavari PML-46, DWN M-3, KG OS DW III 62, and KG DWN 98/2-1) of Krishna-Godavari Basin, Bay of Bengal and processed samples were analyzed by ICP-MS for Pb, Cr, As, and Cd. Comparison of average results in studied 6 blocks with various seawater quality guidelines is discussed to assess the present contamination. It reveals that seawater in study area are not contaminated with respect to perceived heavy metals. Generated data will assist in future for proactive measures and minimize the impact of anthropogenic sources.

Published: March 2022

The vortex of the financial crisis that struck European countries did not impact them as it has primarily affected the Mediterranean periphery. Instead, Greece was the prominent victim, both in terms of duration and size of crisis, with radical changes implemented. The present study explores the determinants of administrative and organizational amendments in the general rural administration during the economic crisis. Data were gathered through a qualitative survey with public officers and stakeholders and were gauged through a Delphi policy framework. The empirical study focuses on implementing crisis management and change management practices in the public sector. The results indicated that public administration was neither prepared to confront the crisis nor the changes that followed. On the other hand, stakeholders claim that despite all the changes that have occurred, the bureaucracy was unaffected and that there is a need for public services to be enhanced. The lessons derived suggest more profound shifts in the administrative practice, culture, implementation of organizational knowledge and tools to deal with crises and changes combined with organizational learning.
Impact de la crise sanitaire Covid-19 sur les petites exploitations agricoles et perspectives pour un système alimentaire durable en Tunisie
Authors: Koussani Wafa , Khamassi Faten
Published: March 2022

Covid-19 had a negative effect economically and socially in Tunisia, as illustrated by the highest mortality rate recorded in Africa in March 2020 and the economic growth rate estimated at -9.3% by the Central Bank of Tunisia in 2020. The main cause of this situation is the quarantine and the sudden halt of several activities resulting in the drop in domestic demand and the loss of Tunisia’s main trading partners. The agricultural sector, and particularly small and family farms, forced to align with the quarantine measures since March 2020, have suffered the full impact of Covid-19. Indeed, the pandemic crisis put a strain on food supply chains: a complex network of interactions involving farmers, agricultural inputs, processing plants, retailers, and others.

In patients with COVID-19, histological examination of the pulmonary vessels shows serious disorders (local thrombosis and microangiopathy), significantly different to those in the control group composed of patients with influenza. Some studies have shown that coronavirus enters cells by binding angiotensin-converting enzyme 2 which is found mainly on the alveolar epithelium and endothelium. The increase in D-dimer levels is typical for patients with COVID-19. Although many inflammatory processes can affect D-dimer levels, an increase in D-dimer during COVID-19 is more likely to indicate thrombosis. The aim. To analyze the patients who have suffered from COVID-19 and to determine possible risk factors for the development of thrombotic complications and define the surgical or medical therapy tactics. Material and methods. The study was conducted from October 2020 to April 2021 in Ukraine (Zaporizhzhia, Uzhhorod, Kherson and Kyiv). We analyzed 121 patients aged 46.9± 15.3 years, 64 (52.8%) men and 57 (47.1%) women. All the patients had positive PCR test for COVID-19. The changes in D-dimer were analyzed. Results. Forty-one (33.9%) patients had thrombotic complications. Pulmonary embolism (PE) was diagnosed in 14 patients, deep vein thrombosis (DVT) in 17, acute stroke in 2 and peripheral artery thrombosis in 8 cases. An increase in D-dimer level was observed in most patients and was not associated with clinical manifestations of thrombosis. At a D-dimer level of 11,000-10,564 ng/ml the patients had clinical symptoms of thrombotic condition which was confirmed by computed tomography or ultrasound examination. At an increase over 725-7000 ng/ml, there were no clinical signs of thrombosis. We performed standard medical therapy in patients with PE and DVT. In case of arterial thrombosis open surgery was performed in 4 patients and direct catheter thrombolysis in 1 case. Conclusion. In our opinion, anticoagulants should be prescribed for patients with a D-dimer level of more than 700 ng/ml. Full anticoagulation is prescribed for severe forms of COVID-19 or confirmed thrombosis. We didn’t find any correlation between the development of thrombotic complications in patients with COVID-19 and comorbidities, body mass index and other factors. Medical therapy was successful in all cases of PE and DVT, anticoagulants were prescribed for 1 year. Femoral artery thrombectomy was successfully performed in 4 patients. After direct catheter thrombolysis we got peripheral pulse. In all cases of arterial thrombosis, we prescribed anticoagulants for 2 months after discharge and acetylsalicylic acid for a long time.

Аналіз літератури показав, що на міжнародному і національному рівні спостерігається зниження кількості надзвичайних ситуацій техногенного походження в порівнянні з природними катастрофами. Ризик виникнення аварій на потенційно небезпечних об'єктах з виникненням осередків ураження тих, що мають пожежний, вибуховий і хімічний характер, залишається практично незмінним і високим. В процесі аналізу літератури встановлено, що при оцінці ймовірності реакції системи на величину подразника, що приймає значення деякої випадкової величини, використовують дві групи методів. Перша група заснована на відмові від використання попередньої інформації про закон розподілу величини подразника (метод логіт-функції), друга – на використанні цих відомостей (метод пробіт-функцій). Розрахована таблиця логіт-функції для заданої ймовірності появи реакції системи. Розраховано таблиці пробіт-функції для напівнормального розподілу. Розраховано таблиці пробіт-функцій для негаусових розподілів, а саме: розподілу Коші, логістичного розподілу, розподілу мінімального значення, розподілу максимального значення, косинус-розподілу, розподілу гіперболічного секанса, показникового розподілу та обґрунтовано цей вибір. Встановлено, що при ймовірності 0,2<P<0,9 та єдиної сталої величини А, яку використовують в процесі обчислення пробітів, у нашому випадку А=32, значення пробіт-функцій Pr для нормального розподілу Коші, логістичного розподілу, розподілу мінімального значення, розподілу гіперболічного секанса мало відрізняються між собою. Побудовано регресійну модель, яка дає можливість по заданій ймовірності реакції системи визначати значення її функції пробіту. Також побудовано спряжену до неї регресійну модель, яка дає можливість по заданій величині функції пробіту визначати ймовірність реакції системи.
Clinical Considerations Regarding the Use of Touch in Psychotherapy
Authors: Guest Diana , Parker Jan
Published: March 2022

The use of touch in psychotherapy has been a topic of discussion since Freud stopped touching his patients. Psychology in general has moved away from utilizing touch as a therapeutic intervention. However, several body-oriented clinical approaches, such as Bioenergetic Analysis, Neo-Reichian therapy, Core Energetics, Hakomi, and Somatic Experiencing, include touch as approved interventions. This article explores how touch can be used ethically in clinical practice. Types of touch and ethical considerations are discussed as well as the need for training and more research.
Pluralities
Authors: Francisco Maria Cristina
Published: March 2022

Plurality is a conceptual tool that makes diversity explicit. Its importance lies in the theoretical field of studies. Plurality encompasses social values, collective lifestyle, ethics, respect, justice, knowledge of various cultures, and the impact of physical and psychological suffering created by prejudice and discrimination. Understanding the different types of knowledge and the mechanisms that keep them concealed and that affect them can contribute to reducing prejudice, fear, and insecurity in the face of the unknown. A confrontation occurs in the presence of insecurity. Fear and anger emerge, and violence becomes an act of eliminating that which is considered threatening. Moreover, the contemporary context adds technology, competition, and speed to this equation, and the result impacts our lives, disconnects us, and anesthetizes our social and emotional bodies. As a principle of plurality, diversity is key to our lives. There is no survival without transformation. We and the world are in constant change. This involves action, learning, and both personal and social experience.

Leadership for inclusion and special education: Novice teachers walking the walk.
Authors: KİNG Fiona , LOGAN Anna
Published: March 2022

Expectations of teacher leadership for school improvement have gained increasing currency in recent years. While extensive research on teacher leadership and practicing teachers exists, comparatively little research exists at pre-service level and there is little empirical data regarding leadership experiences and practices of novice teachers particularly in the context of leadership for inclusion. This paper draws on empirical data from six primary teachers in the Republic of Ireland who had undertaken a leadership for inclusion and special education module in their pre-service education and evidenced their willingness and readiness to practise leadership in schools. During their first year of teaching the teachers were engaged in a community of practice to help bridge the knowledge practice gap related to leadership for inclusion. A visual ethnographic research approach was used to track the teachers as they transitioned from ‘talking the talk to walking the walk’. Analysis of results indicates teachers’ ability to exercise leadership in their own classrooms, in collaboration with others within and beyond their schools. This paper extends the knowledge base on how leadership development in pre-service education evolves in the experiences and practices of a group of novice teachers and subsequent implications for teacher educators.
The Academic Home of Turkish Higher Education Research: A Demographic, Thematic and Methodological Examination of Doctoral Dissertations
Authors: ÖZDEMİR Murat , AYPAY Ahmet
Published: March 2022

This study elaborates on the epistemological foundations of Turkish higher education research drawing on data from 854 doctoral dissertations with an analytical framework based on the institutional organization of researchers and knowledge, the object of study, and the object of knowledge. The results imply that the long-established state higher education institutions (universities) have been the power engines of Turkish higher education research, which gained momentum with the millennium. Male gendered, full professorship, single supervision, and local PhDs were the salient features of advisors. The primary objects of study were topics related to student experience, institutional management, and teaching and learning. As for the object of knowledge, Turkish higher education research was found to be descriptive, regardless of the adopted research methodology. The doctoral dissertations within a maximum of ten different universities and 600 respondents, based on random sampling, had a commanding lead. Undergraduate students and state universities were also fertile components. The paper concludes by proposing the establishment of a dynamic resource database and the incorporation of certain theories and approaches in Turkish higher education research.

The LGBTI Rights in European Union – Do Survivals get Pension?
Authors: Roots Lehte
Published: March 2022

The rights and discrimination of LGBTI people is constantly changing in the time and space. The approach to this specific group of people depends from the values and morality that is prevailing in the leading political parties of the state. All humans are equal and the first article of Universal Declaration of Human Rights states that „all human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood”. This basic universal value seems to be forgotten in case of giving rights to LGBTI people. European case law has also fixed the superiority of the EU in this matter and some cases of the CJEU will be discussed to give an example of the power of interpretation of law. It shows how limiting one right (survival’s pension) will change also the power balance in same-sex partnership. This article will explore and analyse the legal, political approaches to LGBTI rights in European Union using the examples of Estonia and Poland. Keywords: Partnership; Same sex union; Charter of Fundamental Rights; Discrimination; LGBT; Human rights: Family rights; Survival’s pension
Corporate Social Responsibility in Developed as opposed to Developing Countries and the Link to Sustainability
Authors: Gajadhur Revantha
Published: March 2022

This article reviews and incorporates the findings of academic Corporate Social Responsibility (CSR) and sustainability studies to guide hotels in achieving sustainability through CSR initiatives. To date, limited empirical research on CSR in developing countries is available. A triple-bottom-line approach employs companies to balance the needs of stakeholders, allowing them to give back to society while still prospering. Organisations follow CSR activities for a number of reasons, including enhancing the organisational image and strengthening relationships with consumers and stakeholders. CSR is most widely used in developed countries, such as the USA, Canada, and the UK. Consequently, given the lack of progress in CSR implementation in the developing world, this article illustrates some of the gaps identified in developing countries. This is significant because, for the first time, scholars in developing countries are exploring deeply into the concept of CSR. Thus, the article clearly sets the stage for businesses to participate in CSR activities by identifying the return and advantages of making investments for CSR activities within its relevant sectors. In other words, investigating the relationship between CSR and company performance. This article fills the gap and is unique in that it analyses existing CSR practices and offers guidance to business organisations.

The least dimonoid congruences on relatively free trioids
Authors: Zhuchok A. V.
Published: March 2022

When Loday and Ronco studied ternary planar trees, they introduced types of algebras,called trioids and trialgebras. A trioid is a nonempty set equipped with three binary associativeoperations satisfying additional eight axioms relating these operations, while a trialgebra is justa linear analog of a trioid. If all operations of a trioid (trialgebra) coincide, we obtain the notionof a semigroup (associative algebra), and if two concrete operations of a trioid (trialgebra)coincide, we obtain the notion of a dimonoid (dialgebra) and so, trioids (trialgebras) are ageneralization of semigroups (associative algebras) and dimonoids (dialgebras). Trioids andtrialgebras have close relationships with the Hopf algebras, the Leibniz 3-algebras, the Rota-Baxter operators, and the post-Jordan algebras. Originally, these structures arose in algebraictopology. One of the most useful concepts in algebra is the free object. Every variety containsfree algebras and free objects in any variety of algebras are important in the study of thatvariety. Loday and Ronco constructed the free trioid of rank 1 and the free trialgebra. Recently,the free trioid of an arbitrary rank, the free commutative trioid, the free n-nilpotent trioid, thefree rectangular triband, the free left n-trinilpotent trioid and the free abelian trioid wereconstructed and the least dimonoid congruences as well as the least semigroup congruence onthe first four free algebras were characterized. However, just mentioned congruences on freeleft (right) n-trinilpotent trioids and free abelian trioids were not considered. In this paper, wecharacterize the least dimonoid congruences and the least semigroup congruence on free left(right) n-trinilpotent trioids and free abelian trioids.
Slice holomorphic functions in the unit ball: boundedness of $L$-index in a direction and related properties
Authors: Bandura A. I. , Salo T. M. , Skaskiv O. B.
Published: March 2022

Let $\mathbf{b}\in\mathbb{C}^n\setminus\{\mathbf{0}\}$ be a fixed direction. We consider slice holomorphic functions of several complex variables in the unit ball, i.e. we study functions which are analytic in intersection of every slice $\{z^0+t\mathbf{b}: t\in\mathbb{C}\}$ with the unit ball $\mathbb{B}^n=\{z\in\mathbb{C}^: \ |z|:=\sqrt{|z|_1^2+\ldots+|z_n|^2}<1\}$ for any $z^0\in\mathbb{B}^n$. For this class of functions we consider the concept of boundedness of $L$-index in the direction $\mathbf{b},$ where $\mathbf{L}: \mathbb{B}^n\to\mathbb{R}_+$ is a positive continuous function such that $L(z)>\frac{\beta|\mathbf{b}|}{1-|z|}$ and $\beta>1$ is some constant.For functions from this class we deduce analog of Hayman's Theorem. It is criterion useful in applications todifferential equations. We introduce a concept of function having bounded value $L$-distribution in direction forthe slice holomorphic functions in the unit ball. It is proved that slice holomorphic function in the unit ball has bounded value $L$-distribution in a direction if and only if its directional derivative has bounded $L$-index in the same direction. Other propositions concern existence theorems. We show that for any slice holomorphic function $F$ with bounded multiplicities of zeros on any slice in the fixed direction there exists such a positive continuous function $L$that the function $F$ has bounded $L$-index in the direction.

During the winter season of 2020, a field experiment was undertaken in the western zone of Tamil Nadu to assess the effects of organics and inorganics on the growth, yield, and soil properties of rice, Oryza sativa var. CO 51. The experiment was framed in Random Block Design (RBD) comprising of 8 treatments viz., Recommended dose of fertilizer Soil Test Crop Response (STCR) approach (T1), RDF 75 % + Farm yard manure @ 12.5 t ha-1 (T2), T2 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T3), RDF 75 % + Vermicompost @ 5 t ha-1 (T4), T4 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T5), FYM @ 12.5 t ha-1 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T6), Vermicompost @ 5 t ha-1+ Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T7) and absolute control (T8) , replicated thrice. Among the integrated nutrient management practices, T5 proved its superiority over other treatments with respect to growth and physiological parameters followed by T3. This would have been because of the solubilization of phosphorus in the soil by AM organisms which is made accessible for crop growth. Utilization of biofertilizer enhanced the N availability and solubilized the inaccessible phosphorus, which thus recorded higher N accessibility and better phosphorus uptake when applied along with a recommended dose of fertilizer for rice.

Air pollution is one of the major problems in the Delhi NCR region due to industrial emissions, traffic congestion, population growth and rapid development. Air pollutants deteriorate the environment, human health, plants and crops. This study focuses on the physiological parameters and yield attributes of paddy and wheat crops in the vicinity of a gas-based national thermal power plant (NTPC) located in Faridabad. Ten sites were selected, including the control site within a 10 km aerial distance from the exhaust chimney stack of the power plant. Major air pollutants, such as NOx, SOx, O3, and PM10, were monitored using Central Pollution Control Board (CPCB) guidelines. The air quality index (AQI) was moderately polluted at the sampling site, while good air quality was observed at the control site. The results showed that the photosynthetic rates were reduced to 46% in paddies and 48% in wheat crops. In the vegetative growth stage of paddies and wheat crops, the stomatal conductance of paddies decreased to 0.11 mmol m-2s-1 compared to 0.19 mmol m-2s-1 at the control site. The transpiration rate ranged from 0.6 to 7.7 μmol/m2/s in paddies and 1.2 to 9.8 μmol/m2/s in wheat crops. The R2 value ranged from 0.702 to 0.985, which shows a strong impact of the air quality index on the physiological parameters of crops. The yield reduction due to air pollution in paddies was 11.6%, and in wheat crops, it was 14.8%. This study also provides an inventory of air pollutants in Faridabad region and their subsequent impacts on crops.

In the literature, a variety of dairy products are made from goat milk; however, information related to the manufacture of rasogolla from goat milk is very scant. During preliminary trials, it was observed that chhena prepared from goat milk was not suitable for the preparation of rasogolla because it has a very soft and sticky body that is difficult to handle. Therefore, this investigation was conducted to formulate an acceptable quality goat milk rasogolla using whey protein concentrate (WPC) as a functional ingredient. Chhena (also known as Indian cottage cheese, a heat- and acid-coagulated indigenous dairy product) was prepared from fresh Surati goat milk (3.5% fat/8.5% milk solids-not-fat (MSNF). Twelve batches of rasogolla were prepared from chhena coagulated at three temperatures viz. 75, 80 and 85⁰C containing WPC at 4 levels (i.e., 0, 0.25, 0.50 and 0.75% w/w of milk). Rasogolla prepared from chhena containing 0.50% WPC in milk  and coagulated at 80°C was preferred the most with respect to all the sensory attributes evaluated. It had significantly (P<0.05) highest sucrose content, i.e., 35.73% and a higher sugar absorption ratio, i.e., 2.63, compared to all the other experimental samples. The composition of drained samples of goat milk rasogolla was as follows: moisture 50.07%; protein 7.04%; fat 6.44%; ash 0.45% and sucrose 35.73%. The pH was 6.34 and acidity was 0.76% lactic acid. Based on the results obtained in this study, a method was developed for the preparation of acceptable quality goat milk chhena and rasogolla.

The solubility and bioavailability  of zinc  in the soil  determinethe efficiency of Zn fertilizers. A two-year (2018 and 2019) field experiment was performed to study the effectiveness of  Zn sources combined with Zn solubilizing microorganisms, ZSM (Acinetobacter calcoaceticus + Pantoea agglomerans) and cow dung, in rice cv. HUR105 in alluvial soil at the Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh. Among various treatments, the treatment (T8)  9.8 kg ZnO  ha-1 with ZSM showed better grain and straw yields. However, 25.0 kg ZnSHH ha-1+ ZSM (T6) was found to be statistically comparable to  the treatment (T8). The addition of cow dung (CD)  decreased the grain yield in  T11 ( 9.8 kg ZnO ha-1 + ZSM + 200 kg CD ha-1) and T12 (14.6 kg ZnO ha-1 + ZSM + 200 kg CD ha-1), except  the treatment (T10) 4.9 kg ZnO + ZSM + 200 kg CD ha-1. Partial factor productivity of applied Zn varied from 347.2 to 1762.2 and 369.6 to 1855.6 kg grain kg-1 Zn, physiological Zn efficiency varied from 487.4 to 2075.3 and 775.5 and 2035.2 kg grain kg-1 Zn absorbed, agronomic use efficiency of Zn ranged from 20.1 to 189.6 and 28.7 to 180 kg grain kg-1 Zn, the recovery efficiency of Zn fertilizer varied from 3.58 to 11.9% and 3.57 to 11.8% among the treatments in both  seasons, respectively. The maximum gross and net return were documented by T8- 9.8 kg ZnO ha-1 + ZSM, and 23.9% and 28.5% over the control due to higher grain yields.
Contribution to developing a new environmental risk management methodology for industrial sites

A fundamental requirement of any environmental management system for industrial sites is the identification and assessment of risk. To meet international standards in terms of environmental protection and preservation, industrial sites should ensure that a comprehensive environmental risk management process is in place by systematically identifying and managing risks arising from internal and external factors. The purpose of this study was to develop a new methodology to determine the significance of environmental hazardous situations associated with a process or activity. It uses qualitative or quantitative techniques to pinpoint weaknesses in design, operation, and lines of defense provided by engineering and administrative controls, which can lead to an environmentally hazardous event. It may also provide an assessment of risk resulting from the magnitude of the consequence and the probability of the environmental event occurring. The fundamental principle of this new risk-based hazard methodology is that whilst risk cannot be eliminated, it should be possible to reduce to ALARP (as low as reasonably practicable), and the environmental risk matrix could be a useful tool for establishing if an environmental risk rating is tolerable or not based on the likelihood and consequences. The outcome of this study is developing a new environmental risk matrix based on different consequences (health, environmental, reputation, and business interruption) with likelihood criteria. This matrix could be applied by industrial sites to identify and control their environmental risks.
Abamectin exposure during lactation triggering oxidative stress and expression pattern of Bcl-2 perturbation in rat pups brain
Authors: Ziada Reem M
Published: March 2022

Pesticides, for example, are thought to be essential drivers of brain injury and dysfunction. Abamectin (ABA) is by far the most routinely used pesticide in farming and healthcare, and its toxicity to nontarget organisms has attracted considerable interest. The effect of abamectin pesticide delivered at the postnatal period on the antioxidant defense system was assessed. This study also examined apoptotic gene expression indicators in the brains of rat pups over neonatal weeks. Pregnant Wister rats were split into two groups: G1 received deionized water (control), and G2 received 0.211 mg/L of abamectin. The first day of abamectin exposure was the first day after delivery and continued until the tenth day of lactation. After 10 days (mid lactation) and the lactation period, rat pup brain samples were taken for oxidative biochemistry investigations and apoptotic gene expression (RT–qPCR). In comparison to the control group G1, Abamectin reinforces protein carbonyl levels and glutathione-based enzymes (transferase and peroxidase), whereas superoxide dismutase and glutathione levels are reduced in the pup's brain. Furthermore, Abamectin induced considerable upregulation of proapoptotic (Bax) and antiapoptotic (Bcl-2) mRNA gene expression. Overall, our findings characterize the relationship between brain changes and abamectin administration during lactation periods, even at low doses that are considered safe, and indicate that this abamectin insecticide is harmful to the growing neurological system.

Authors: Rai Gayatri , Mahobiya Payal
Published: March 2022

The present study aimed to investigate the ameliorative effect of curcumin and ascorbic acid against ultraviolet (UVB)-induced thyroid toxicity and to study the haemtological and biochemical parameters. Twenty-four female Wistar rats, aged 3-4 months and weighing 130-150 g, were used, and the rats were divided into four Groups (Groups I to IV). Group I received standard food and water ad libitum and was treated as a control; Group II received a dose of 280 nm of UVB radiation for 2 hrs/day. Group III received 280 nm UVB radiation for 2 hrs/day and received curcumin 25 mg/kg body weight given orally. Group IV received 280 nm of UVB radiation for 2 hrs/day and received ascorbic acid 250 mg/kg body weight given orally. All the treatments were consequently performed for 15 days. The results showed that haemtological parameters such as haemoglobin (Hb) (p<0.05), red blood cells (RBCs), white blood cells (WBCs), MCV, MCH, and MCHC decreased significantly. Biochemical parameters included lipid peroxidation (LPO) (p<0.05), H2O2 (p<0.01), nitric oxide (NO), superoxide dismutase (SOD) (p< 0.01), catalase (p<0.01), glutathione-S-transferase (GST) (p<0.01), and glutathione reductase. NO increased, and glutathione (GSH) (p<0.01) decreased significantly. However, cotreatment with curcumin and ascorbic acid significantly increased the haemtological parameters. In addition, oxidative parameters such as LPO (p<0.01), SOD (p< 0.01), CAT (p<0.01), GST (p<0.01), and NO (p<0.01) significantly increased, and GSH (p<0.01) significantly decreased upon cotreatment with curcumin and ascorbic acid. The results indicated the ameliorative effect of curcumin and ascorbic acid against UVB-induced thyroid toxicity in female Wistar rats.
