As countries placed tight restrictions on travel to curb the spread of the virus, the COVID-19 pandemic spread with alarming ease, infecting millions and bringing economic activity to a practical standstill. The Global Economic Prospects for June 2020 define both the immediate and short-term outlook for the effects of the pandemic and the long-term harm it has spread to growth prospects. Despite the unprecedented efforts of governments to fight the slowdown with fiscal and monetary policy support, the baseline projection envisages a 5.2 percent contraction in global GDP in 2020 using market exchange rate weights, the worst global recession in decades. The deep recessions caused by the pandemic are projected to leave lasting scars over the long view through lower investment, the depletion of human resources through a job and school losses, and the breakdown of global trade and supply links.

Grafting of Acrylonitrile onto cellulose from different sources, using a variety of chemical initiators under various reaction conditions has been thoroughly investigated and reported. Hydrophobic nature of acrylonitrile hinders the partition of metal ions form aqueous phase thus narrows the applicationspectrum of its graft copolymers inseparation and enrichment processes. However, this drawback can be improved by post functionalization of nitrile (-CN) group to generate hydrophilic/ionic moieties by simple reactions like hydrolysis or substitution. In present study, acrylonitrile (AN) was grafted onto commercial cellulose to produce graft copolymers which can be used as starting materials for development of efficient metal ions sorbents. Grafting was carried out by redox initiation method using Ce+4 ions following the earlier reported scheme at the optimum grafting conditions worked out for grafting of AN onto  cellulose ether, Hydroxyethyl cellulose(HEC). Graft copolymer thus obtained [hereafter called cell-g-poly (AN)] was characterized by Elemental analysis and FTIR. Both, cellulose and HEC belong to same back bone therefore, exhibited similar behaviour towards grafting. Percent grafting (Pg =50) obtained in case of cellulose was in close agreement with (Pg=55.5) that observed in case of HEC. Cell-g-poly (AN) served as useful precursor to develop reactive metal ion sorbing polymer supports as nitrile (-CN) moiety of poly (AN) is amenable to post functionalization and could be conveniently modified to targeted metal ion chelating amido-oxime group [poly (NH2-C=NHOH))] thus  the resultant polymer  could be used as a novel support for metal ion sorption.

Unlike conventional installed frames, for example, secure glossy cards, which develop deeply embedded protected frames, such as implantable in addition to portable clinical devices, must have a larger "attack surface". A security breach in such frames that plug deep into human bodies or elements would be dangerous, so adopting conventional arrangements is probably not practical due to the strict limitations of these often battery-controlled frames. Unfortunately, although the development of encrypted scanning systems has begun to solve this basic problem, undergraduate education (both undergraduate and graduate level) is equally weakened. One of the important explanations behind this slowness is the multidisciplinary nature of the development of security bottlenecks (arithmetic, engineering, science and pharmaceuticals, to name a few). In light of the inspiration mentioned above, in this article we present a successful exploration and training system to conquer this topic at the Rochester Institute of Technology. Furthermore, we present the consequences of more than a year of implementation of the methodology introduced at the degree level in contextual investigations complete with "assaults on the secondary station exam.

The organic farming system follows various principles of natural ecosystem which is based on the structural and functional relationships of natural ecosystems. The food production historypresume that organic farming  was the predominant cultivation method practiced for last decade, but in the beginning of the twentieth century we observed the advanced biochemistry and bio-engineering  immensely changed cultivation system  by uses synthetic fertilizers and pesticides(Fabiansson, 2014). But the consumption of organic food has seen a marked increment around the globe in the past decade. The common reports suggested that organic foods have a better taste as compared to the other conventional kinds, primarily because the crops have been given more time to develop and mature, in addition to usage of environment friendly agricultural techniques.As organic foods and conventional products are close substitutes, consumers conveniently choose the cheaper, conventional category and thus, limiting the demand for organic food. It is difficult to justify the price premium to the consumers as health benefits from organic food consumption cannot be particularly quantified.Organic farming and its coordination and administration enhance the environment as well as human health which have an important objective for all credible economic food production and growth.

A major environmental issue in the world is pollution in cement production. Geopolymer concrete also in construction industry is an alternate cement material as well as an eco-friendly material. Using fly ash, ground granulated blast furnace slag as base materials and sodium hydroxide and sodium silicate combination as alkaline activators, the geopolymer concrete is prepared. The sand is an important part of concrete; it is mainly procured from natural sources. Environmental and economy aspects are better obtained, if locally available sources can be used. Manufactured sand substitutes the fine aggregate in the concrete in several percentages as the sand is well graded and gives greater concrete power.  In the present analysis, the strength of concrete with manufactured sand is studied in proportions of different percentage as a replacement for natural sand.

Destitution is a monetary state where individuals are encountering shortage or the absence of specific products that are required for the lives of people like cash and material things. Accordingly, destitution is a multifaceted idea comprehensive of social, monetary and political components. Destitution has become an incredible issue in our reality. Despite the fact that numerous associations have been made to find answers to this issue, no one could fully spare our reality from destitution. The most well-known fact that we can understand when contemplating destitution data is that neediness normally exists in the development of nations. Around 25 percent of the population currently lives in deteriorated need, according to them. Undoubtedly, even the assembly of India has yielded that around 20 crore people in India live in a state of pathetic destitution with no permission to minimized drinking water, purification, and two complete meals. In light of these issues I should think about the challenges of desperation and its causes in India and its sorts.

The main objective of aircraft aerodynamics is to enhance the aerodynamic characteristics and manoeuvrability of the aircraft. This enhancement includes the reduction in drag and stall phenomenon. The airfoil, which contains dimples, will have comparatively less drag than the plain airfoil. Introducing dimples on the aircraft wing will create turbulence by creating vortices, which delays the boundary layer separation resulting in decrease of pressure drag and increase in the angle of stall. In addition, wake reduction leads to reduction in acoustic emission. The overall objective of this study is to improve the aircraft manoeuvrability by delaying the flow separation point at stall and thereby reducing the drag by applying the dimple effect over the aircraft wing. This Study includes computational analysis of dimple effect on NACA 0018 airfoil. Dimple shapes of square selected for the analysis; airfoil tested under the inlet velocity of 30m/s at different angle of attack (12˚, 14˚, 16˚, 18˚,) for 8mm & 10mm diameter of Dimples. This analysis favours the dimple effect by increasing L/D ratio and thereby providing the maximum aerodynamic efficiency, which provides the enhanced performance for the aircraft

An Introduction to Plant Growth Promoting Rhizobacteria, Antifungal Metabolites Biosynthesis using PRPR with reference to Pseudomonas species and It’s other characteristics like Antagonistic and Biocontrolling properties

Plant Growth Promoting Rhizobacteria (PRGR) are the rhizosphere bacteria that help  in the enhancement of plant growth by a variety of mechanisms like phosphate solubilization, siderophore production, biological nitrogen fixation, rhizosphere engineering, production of 1-Aminocyclopropane -1carboxylate deaminase (ACC), quorum sensing(QS) signal interference and inhibition of biofilm formation phytohormone production, exhibiting antifungal activity, production of volatile organic compounds (VOCs), induction of systematic resistance, promoting beneficial plant microbe symbiosis, interference with pathogen toxin production etc. It is generally free living, soil borne bacteria. The potentiality of PGPR is continuously increasing as it offers us a good way to replace the chemical fertilizers, pesticides as well as directly or indirectly influence the whole morphology of the plants and play a vital role in crop protection, growth promotion and in the improvement of soil health. Some well known PGPR Strains are Pseudomonas, Bacillus, Azospirrillum, Rhizobium and Serratia species. Different strains of PGPR are capable of secreting antifungal metabolites (AFM) like siderophore, chitinase and hydrogen cyanide. For example Pseudomonas fluorescens belonging to PGPR class produce siderophore and control Phythium ultimum and Pseudomonas stuzeri produce chitinase which lyse the cell wall of Fusarium solani. Antifungal metabolites produced by these Rhizobacteria were identified as antibiotics ( iturin, surfactins, fengycin, DAPG, Phenazine etc, ), cell wall degrading enzymes( proteses, chitinases, cellulases), plant growth promoting enzymes and hormones  (indole-3-Acetic Acid, ACC-deaminase, phosphatase, nitrogen fixation), N-acylhomoderine lactones and sideophore. Due to synthesis of antifungal metabolites PGPR also used as a biocontrol agent in case of many diseases for instance, it degrades fusaric acid produced by Fusarium sp. That is a causative agent of wilt. They also help plants to be resistant against biotic stresses via direct antagonism to pathogens or by induction of systematic resistance to pathogens. It mostly trigger induced systematic resistance via methyl jasmonate and methyl salicyclate in plants.

This paper focuses on those parts of 20th century applied mathematics that have entered into the toolkit of ecology. Historically, the recent trend of applying mathematics to ecology is discussed. It is proposed that this new development can be seen in the extension of its application as the natural development of applied mathematics. There is no assumption that the mathematical concepts and methods employed would be significantly different from those used in mainstream applied mathematics. In terms of estimates for reference to empirical data, conventional concepts and methods of statistical physics can be successfully applied. A case study on the history of statistics and operational research discusses several ways to integrate the development of applied mathematics of the twentieth century into an ecological context.

Word Sense Disambiguation (WSD) is one of the most challenging problems in the research area of natural language processing.  To find the correct sense of the word in a particular context is called Word Sense Disambiguation. As a human, we can get a correct sense of the word given in the sentence because of word knowledge of that particular natural language, but it is not an easy task for the machine to disambiguate the word. Developing any WSD system, it required sense repository and sense dictionary. It is very costly and time-consuming to build these resources. Many foreign languages have available these resources, that is why most of the foreign languages like English, German, Spanish etc lot of work is done in these Natural languages. When we look for Indian languages like Hindi, Marathi, Bengali etc. very less work is done. The reason behind this is resource-scarcity. In this paper, we majorly focus on Marathi Language Word Sense Disambiguation because of very less work is done in the Marathi Language as compared to Hindi and other Indian Languages. Our main objective is to provide information about various resources available for the Marathi language which will be helpful for researchers who wants to do work for Marathi WSD. This paper also gives a review on work done for Marathi Language WSD and its challenges and problems.

Education is continuing its journey since man is on earth. It may be the nature taught man in the yester years, gurukulas in the golden period of many kings, Government Schools and colleges’ post-independence era and convents, international schools, deemed universities in the 21st century, its common objective of all these institutions is to educate the human race. Education is not just reading the books and getting a degree from a University, it is the holistic development of an individual physically, mentally, financially and economically. The aim of education is to bring overall development of an individual and make him today a productive citizen, for tomorrow’s nation. Every country develops its education system to express and promote its unique socio-cultural identity and to meet the growing demand of job and career opportunities. The country has reached a stage in economic and technological progress and efforts must be made to ensure that the fruits of change reach all the sections of the society. The National Education Policy- 1986 focused on common curriculum framework that contains a common core along with other components that are flexible. Child-centric approach is given prominence in elementary education, followed by secondary education giving prominence to girl child education and SC, ST and BC categories of education. The National Education Policy-2020, which is reformed after 34 years, emphasized more on holistic approach with multi-disciplinary courses and students are facilitated with bucket system of choosing subjects of their interest. This paper focuses on the comparative study on the highlighted aspects of NEP of both 1986 and 2020.
