SIR Model with Homotopy to Predict Corona Cases

In this chapter, we will discuss SIR model to study the spread of COVID-2019 pandemic of India. We will give the prediction of corona cases using homotopy method. The HM is a method for solving the ordinary differential equations. The SIR model consists of three ordinary differential equations. In this study, we have used the data of COVID-2019 Outbreak of India on 20 Jan 2021. In this data, Recovered is 102656163, Active cases are 189245 Susceptible persons are 189347782 for the experimental purpose. Data about a wide variety of infectious diseases has been analyzed with the help of SIR model. Therefore, this model has been already well tested for infectious diseases by various scientists and researchers.

Effects of Cytokinins on in vitro Culture of Bauhinia purpurea L.

Bauhinia purpurea L. is a moderate-sized tree with multipurpose value tree yields gum, its bark contains tannin and leaves are used as fodder. It is distributed in sub-Himalayan tracts. The main objective of this study was to evaluate the effects of different cytokinins on growth parameters of B. purpurea and develop a standard micropropagation protocol for nodes and shoot proliferations. The cytokinins used in this study were N-Benzyl-9(2-tetrahydropyranyl) (BPA), 6-furfurylaminopurine, Kinetin (Kn), 6-(4-Hydroxy-3-methyl-trans-2-butenylaminopurine) (Zeatin) (Zin), 2-isopentenyl aminopurine, (2-iP) and 6-benzylaminopurine (BAP) at four different concentrations (0.5, 1.0, 2.0 and 5.0 µM). Murashige and Skoog (1962) (MS) medium was used for the experimental purpose. Multiplication rate of plants was recorded after 8 weeks of culture. Such propagated best grown plants were acclimatized and transferred to the field. All the collected data were worked out statistically with SPSS, a system of analytical procedure

Effect of different algal powder on growth and productivity of Moongbean (Phaseolus radiata)

Various species of algae grow luxuriantly in Ujani reservoir. Those species found in large amount are used for experimental purpose. The effect of selected five algal species (Synechococcus aeruginosus, Spirulina plantensis, Cladophora crispata, Spirogyra jugalis and Chara fragilis) was evaluated as biofertilizer on growth and productivity of Moongbean. From the study it was observed that application of algae on Moongbean gives higher yield compared to control. Statistical analysis showed that there are significant differences in plant height,number of leaves and yield as compared to control.

Centro 3R: Organ and tissue sharing project

To optimize sharing of organs/tissues from animals humanely sacrificed for (scientific or research) projects approved by the Ministry of Health, by considering that functional - but not only functional - experiments often require using fresh tissues, the 3R Centre is establishing a pilot project involving the University of Genoa and the University of Pisa and their OPBA, enabling sharing fresh tissues through platforms on territorial basis (that might be connected on platform networks) allowing the researcher to use at best valuable biological resource. Implementation of the project would allow establishing protocols for organ/tissue sharing including fresh preparations, therefore meeting more requests than the frozen/fixed tissues. The project by allowing strict collaboration and exchange between researchers would complement the Ministry of Health platform for tissue sharing and would contribute to step forward on the effective reduction of animal use for experimental purpose.

SOME SIMULATIONS ON THE PORTFOLIO RISK AND RETURN: A METHODOLOGICAL NOTE

In this study we try to demonstrate mainly from the methodological and pedagogical perspective how investment weights and the correlation between securities are manifested on the portfolio risk and return. Empirical data are examined from 2010 to 2018 and for experimental purpose two companies are randomly selected. Totally five simulations are performed using Excel. The fifth simulation presents the case of optimal proportions for an investor which efforts to minimize the portfolio risk.
