Today, coronavirus appears as a serious challenge to the whole world. Epidemiological data of coronavirus is collected through media and web sources for the purpose of analysis. New data on COVID-19 are available daily, yet information about the biological aspects of SARS-CoV-2 and epidemiological characteristics of COVID-19 remains limited, and uncertainty remains around nearly all its parameters' values. This research provides the scienti c and public health communities better resources, knowledge, and tools to improve their ability to control the infectious diseases. Using the publicly available data on the ongoing pandemic, the present study investigates the incubation period and other time intervals that govern the epidemiological dynamics of the COVID-19 infections. Formulation of the testing hypotheses for different countries with a 95% level of con dence, and descriptive statistics have been calculated to analyze in which region will COVID-19 fall according to the tested hypothesized mean of different countries. The results will be helpful in decision making as well as in further mathematical analysis and control strategy. Statistical tools are used to investigate this pandemic, which will be useful for further research. The testing of the hypothesis is done for the differences in various effects including standard errors. Changes in states' variables are observed over time. The rapid outbreak of coronavirus can be stopped by reducing its transmission. Susceptible should maintain safe distance and follow precautionary measures regarding COVID-19 transmission.
Purpose: Heavy metals contaminate the soil that alters the properties of soil and negatively affect plants growth. Using microorganism and plant can remove these pollutants from soil. The present investigation was designed to evaluate the induced effect of Bacillus pumilus on maize plant in Cadmium (Cd) contaminated soil. Methods: Three different concentrations of Cd (i.e. 0.25, 0.50 and 0.75 mg kg-1) were applied in soil under which maize plants were grown. The germination percentage, shoot length, leaf length, number of leaves, root length,fresh weight and nutrient uptake by maize plant were determined. The experiment was conducted by using complete randomized design (CRD) with three replicates. Results: The result indicated that germination percentage, Shoot length, leaf length, root length, number of leaves, and plant fresh weight were reduced by 37, 39, 39, 32 and 59% respectively at 0.75mg kg-1 of CdSO4concentration but when maize seeds inoculated with Bacillus pumilus significantly increased the germination percentage, shoot length, leaf length, number of leaves, plant fresh weight at different concentrations of CdSO4. Moreover, the plant protein were significantly increased by 60% in T6 (0.25 mg kg-1 of CdSO4+inoculated seed) and Peroxidase dismutase (POD) was also significantly higher by 346% in T6 (0.25 mg kg-1 of CdSO4+inoculated seed), however, the Superoxide dismutase (SOD) was significantly higher in T5 (0.75 mg kg-1 of CdSO4+ uninoculated seed) and was 769% higher as compared to control. The Cd contents in Bacillus pumilus inoculated maize roots and shoots were decreased. Conclusion: The present investigations indicated that the inoculation of maize plant with Bacillus pumilus can help maize plants to withstand Cd stress but higher concentration of Cd can harm the plant. The Bacillus pumilus has good potential to remediate Cd from soil, and also have potential to reduce the phytoavailibility and toxicity of Cd.

Background With the global surge in COVID-19 pandemic, it has become inevitable for everyone, inclusive of nuclear medicine personnel, to play their role in combating and containing its transmission. During fall 2019, China encountered a novel coronavirus in Wuhan city which was later on termed as COVID-19. The pneumonia caused by COVID-19 is characterized by dry cough, fever, fatigue, and shortness of breathing (dyspnea). Until now, this virus has spread worldwide and continues to cause exponential causalities. Main body This global catastrophic scenario calls for stringent measures to control COVID-19 infection. Thus herein, the respective authors have endeavored to review precautionary measures for nuclear medicine department, encompassing its personnel as well as the patients so that intradepartmental transmission can be prevented. This requires development and execution of a robust and dynamic plan elaborating the healthcare guidelines. Hence, our review paper covers the arena of nuclear medicine services in particular. Conclusion Nuclear medicine can play its role in mitigating COVID-19 transmission to personnel and patients if provided with ample PPEs and guidelines are strictly followed. With implementing SOPs (standard operating procedures) based on these guidelines, nuclear medicine facilities will be better prepared for impromptu actions in case of any future outbreak while retaining the smooth flow of obligatory healthcare services.
Cronavirus Disease (COVID-19) episode presents genuine worries to worldwide schooling frameworks. Endeavors to accommodate COVID-19 provoked unexpected lockdown of education sector around the world. Coronavirus school terminations avoided more than billions of students with regards to class. The examination researches the effect of COVID-19 on instruction. The results display COVID-19 effective influences guidance together with, education interferences, and decreased induction to preparing the investigation workplaces, Job incidents and extended understudy commitments. Similarly display the various instructor and understudies depend upon advancement to establish ongoing education digital throughout the COVID-19. In any case, internet preparing was obstruct according to defenseless establishments along with, web, capacity, separation and detachment barrier and destitute mechanized capacities. The assessment accentuate the hurting consequences of COVID-19 on tutoring territory and the necessity for each and every informational foundation, educators, and understudies to get development, and improve their modernized capacities as per the emerging overall examples and genuine variables in preparing.
