The emerging infectious diseases are increasing in frequency exerting significant impact on human health and severely threatening global economy. Now at present, the whole globe is facing the challenges evolved owing to Corona virus (COVID-19) pandemic, which has set the clock backwards on the developmental progress of several nations including India and pauses the global economy owing to repeated lockdowns. The agricultural sector owing to its diverse output (crops, horticulture, dairying, fisheries, etc.) only showed positive growth in Indian GDP (gross domestic product) despite various challenges faced by this sector especially labour shortage, transportation, marketing, etc. The central as well as several state governments also issued supportive steps to favour agricultural related activities and provided incentives to farmers to unlock growth. Still, there is necessity to support and promote digital platforms to scale up on an emergency basis and provide an outlet for the farmers’ produce immediately. The government should think to build storage facilities on villages’ level as well as brought policies to support pricing (minimum support price) for other nutritious cereals like sorghum and millets.

A pot experiment was conducted in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh, to examine the effect of different levels of Zn and B on the major biochemical and nutritional quality of tomato fruits. The experiment was laid out in a completely randomized design (CRD) with 4 replications along with two treatment factors viz., (i) four levels of Zn- like control, Zn @ 4.0 kg ha-1, Zn @ 6.0 kg ha-1 and Zn @ 8.0 kg ha-1; and (ii) three levels of B- like control, B @ 2.0 kg ha-1 and B @ 3.0 kg ha-1. Among the biochemical parameters- lycopene, total acidity, and vitamin C contents in tomato fruits ranged from 3.24-3.76 mg 100 g-1, 0.26-0.36%, and 21.76-26.40 mg 100 g-1 samples, respectively. The study results revealed that the highest amounts of lycopene and vitamin C were recorded from B @ 2.0 kg ha-1. Combined Zn and B applications showed a highly significant effect on total acidity, lycopene, and vitamin C contents of tomato fruits. Similarly, the application of Zn and B alone or in combination significantly affected the major nutrient contents of tomato fruits. The highest amounts of Ca, Mg, Na, K, and P were obtained from the application of Zn @ 4.0 kg ha-1, while the maximum amounts of Fe and Zn were recorded from Zn @ 8.0 kg ha-1 treatment. However, the application of B alone significantly reduced the contents of Ca, P, S, Fe, and Zn in tomato fruits while the contents of Mg, K, and Na remained almost unchanged. Finally, the study results concluded that the combined application of Zn and B (@ 4.0 and 2.0 kg ha-1, respectively) had a significant effect on major nutrients and biochemical characters of tomato fruits.

Environmental geo-forensics which involves an integrated suite of geochemical and geophysical  techniques was used to detect and evaluate contaminant plume migrations from three cemeteries (names of the cemeteries are; First, second and third cemeteries, all in Benin City) within Benin-City metropolis, South-South Nigeria. The study aimed at determining the risks to groundwater and soil by assessing the rate of leachate plume migrations on the study area. The Very Low Frequency-Electromagnetic (VLF-EM) surveys revealed locations of conductive bodies. The Electrical Resistivity Imaging (ERI) surveys showed patterns and resistivity values indicating the presence of leachate plumes around second and third cemeteries, and no presence of leachate around first cemetery. Soil samples from shallow depths within the vicinities of the cemeteries revealed pollution which had probably migrated from the study area. The surface and subsurface soil investigations showed pure laterites which is impervious to fluid flow. Generally, many depressions were identified within the study area, although migration rate is low because it is controlled mainly by the subsurface geology. A time lapse study showed contaminant migration rates of 41.6 cm/month and 51.7 cm/month in the horizontal directions in the second and third cemeteries respectively and 19.2 cm/month in the vertical directions for both (second and third) cemeteries. Also, the arrival time of migrating plumes in laterite layer under was estimated to be 4 years. This investigation demonstrates the suitability of environmental and criminal geo-forensics for identification and evaluation of electrically conductive contaminant plumes, and also to monitor the plume as it travels within the subsurface.

The development of mathematical skills for the primary cycle is a triple challenge in the current context of education in Romania. The first of the challenges is given by the fact that education has become an activity still unstructured with political movements and decisions, implicitly with the changes that have taken place in the ministerial apparatus. The second challenge is given by the methodological changes and of the school curriculum, which comes as a completion of the first challenge, and the third challenge is given by the weight of the teachers in making mathematics an attractive discipline. In this sense, the challenge for us is to show that this triple barrier can be overcome. As such, in the present study, a mixed-method of presenting the mathematical contents in the classroom is proposed, especially for the preparatory group, class I and II, through the prism of the instruments offered by the Romanian thematic philately. The results of the study are presented in the form of worksheets, of which we present only excerpts to summarize the possibilities arising from the association of philately with notions of mathematics training for the primary cycle.

Covid-19, as a pandemic disease around the world, has generated great threat to human society and caused enormous mortality with weak surveillance system. In this paper, we propose a mathematical model to describe the transmission of Covid-19. Moreover, basic reproduction number and the local and global dynamics of the dynamical model are obtained. Then we apply our model to characterize the transmission process of Covid-19 in Nigeria. It was found that, in order to avoid its outbreak in Nigeria, it may be better to adhere to government policy to curtail the spread through person-to-person transmission and make effort to improve personal hygiene as well as early detection and reporting. Our results may provide some new insights for elimination of Covid-19.

Concrete is an essential construction material and major component of concrete is cement. There is a huge amount of carbon dioxide emission into the atmosphere during manufacturing process of cement which has negative impact on the environment. Thus it become necessary to discover a substitute material for cement in concrete. Rapid industrialization generates a significant quantity of waste material which are causing negative effect on environment. These wastes can be a replacement for traditional material which are used in concrete like cement or fine aggregate. Red mud is waste material which generated from bauxite ore at the time of production of aluminium by the Bayer process. In this review paper, the effort is made to present the properties of concrete with red mud after studying several research papers. This paper discusses the properties of red mud concrete such as workability, compressive strength, split tensile strength, flexural strength, water absorption and modulus of elasticity. This paper shows the feasibility of partial substitution of cement in concrete by red mud. The study shows that incorporating red mud resulted increase in strengths of concrete such as compressive, split tensile and flexural strength. The water absorption of concrete decrease as increase in red mud content, it can be established that there is a possibility for using red mud in concrete as a binder ingredient for sustainable construction.

Cement manufacture depletes natural resources, requires significant energy usage, and emits large quantities of greenhouse gases. Roughly one tonne of carbon dioxide is released by ordinary Portland cement, which is roughly 7% of global carbon dioxide generation. In concrete production GGBS can be a partial alternative of cement. GGBS is produced by finely grinding of molten slag generated by the process of extraction of iron from ore. In this study the concrete properties incorporating GGBS is reviewed. The hardened properties of concrete incorporating GGBS are discussed. The cement replacement of about 35-40% by GGBS in concrete demonstrates various advantages like less heat of hydration, increase in ductility, increase in strength, reduction in carbon emission and better aesthetics. GGBS improves the durability properties of concrete, such as higher resistance to sulphate attack, increased resistance to alkali-silica reaction, reduced chloride ion penetration which enhances corrosion resistance. Denser microstructure and lower porosity due to the addition of GGBS, which in turn enhances the durability of concrete. With the use of GGBS in concrete, cement content can be reduced, which turns into an eco-friendly solution.
