After the outbreak of COVID-19 in Italy, thousands of Romanian citizens who worked in Northern Italy, Spain or Germany returned to Romania. Based on the time-dependent susceptible–infected–recovered—SIR model, this paper compares the evolution of the COVID-19 disease between Romania and Italy, assuming that the parameter value of R0 in the time-dependent SIR model decreases to R1 < R0 after publicly announced restrictions by the government, and increases to a value of R2 < R1 when the restrictions are lifted. Among other things, we answer the questions about the date and extent of the second peak in Italy and Romania with respect to different values of R2 and the duration of the restrictions.

Abstract Impact of COVID-19 has been devastating worldwide, it has disrupted lives of people, economy has fallen and millions of people have lost their jobs. Second peak of COVID-19 is making it even worse for many developing countries. In India, the second peak is reaching nearly 4 times the cases that were reported during the first peak, thus making it a challenge for the government to plan for the future without affecting the economy further. According to WHO, millions of enterprises are at existential threat, nearly half of the global workforce is at risk of losing their jobs and the entire food chain has been disrupted. In order to provide some assistance to the situation, this study aims to use the SIR-F Model, which is a variation of the SIR model. W. O. Kermack and A. G. McKendrick in 1927, proposed the model in which they classified a fixed population into three compartments: S(t), susceptible; I(t), Infected; R(t), Recovered. We have used the SIR-F model which differentiates between Recovered (meaning people infected and later recovered and thus now immune) and Fatality. We have simulated two scenarios including one in which we study the impact of medicine on future cases and also inspected various parameters which shed light on reasons behind increasing and decreasing the number of covid cases in India. In the future, this work can be extended further to develop a completely new model to consider those cases in which people have recovered but are still at a risk of reinfection.

The Basic Reproduction Number

In this article, a time-dependent susceptible-infected-recovered (SIR) model is constructed to investigate the transmission rate of COVID-19 in various regions of India. The model included the fundamental parameters on which the transmission rate of the infection is dependent, like the population density, contact rate, recovery rate, and intensity of the infection in the respective region. Looking at the great diversity in different geographic locations in India, we determined to calculate the basic reproduction number for all Indian districts based on the COVID-19 data till 7 July 2020. By preparing district-wise spatial distribution maps with the help of ArcGIS 10.2, the model was employed to show the effect of complete lockdown on the transmission rate of the COVID-19 infection in Indian districts. Moreover, with the model's transformation to the fractional ordered dynamical system, we found that the nature of the proposed SIR model is different for the different order of the systems. The sensitivity analysis of the basic reproduction number is done graphically which forecasts the change in the transmission rate of COVID-19 infection with change in different parameters. In the numerical simulation section, oscillations and variations in the model compartments are shown for two different situations, with and without lockdown.

Abstract Recently, various mathematical models have been proposed to model COVID-19 outbreak. These models are an effective tool to study the mechanisms of coronavirus spreading and to predict the future course of COVID-19 disease. They are also used to evaluate strategies to control this pandemic. Generally, SIR compartmental models are appropriate for understanding and predicting the dynamics of infectious diseases like COVID-19. The classical SIR model is initially introduced by Kermack and McKendrick (cf. (Anderson, R. M. 1991. “Discussion: the Kermack–McKendrick Epidemic Threshold Theorem.” Bulletin of Mathematical Biology 53 (1): 3–32; Kermack, W. O., and A. G. McKendrick. 1927. “A Contribution to the Mathematical Theory of Epidemics.” Proceedings of the Royal Society 115 (772): 700–21)) to describe the evolution of the susceptible, infected and recovered compartment. Focused on the impact of public policies designed to contain this pandemic, we develop a new nonlinear SIR epidemic problem modeling the spreading of coronavirus under the effect of a social distancing induced by the government measures to stop coronavirus spreading. To find the parameters adopted for each country (for e.g. Germany, Spain, Italy, France, Algeria and Morocco) we fit the proposed model with respect to the actual real data. We also evaluate the government measures in each country with respect to the evolution of the pandemic. Our numerical simulations can be used to provide an effective tool for predicting the spread of the disease.

The success of the e-commerce sector is largely dependent on the increasingnumber of retail entrepreneurs, who fall in the unorganized retail sector category. Thegovernment has included such players in the ambit of GST with an intention of broadeningthe tax base and has introduced specific provisions for the e-commerce companies. This isone of the major taxation reforms in Indian taxation system.GST is to set to integrate all stateeconomies and increase the overall growth of the country.GST will create unified market andboost the Indian economy. The Goods and Service Tax (GST) is a value added tax to beimplemented in India.. There are 3 kinds of taxes under GST: 1) SGST 2) CGST 3) IGST.The GST tax rates are divided into 5 categories which are 0%, 5%, 12%, 18%, 20%.Implementation of GST is one of the best decision taken by the Indian Government.

The government has made many laws and regulations, but corruption issues cannot yet be controlled. Police and Prosecuting Attorney Institutions have not yet functioned effectively and efficiently in eradicating corruption. Therefore, the public hopes Komisi Pemberantasan Korupsi (KPK)/the Corruption Eradication Commission eliminates the crime. KPK is considerably appreciated by the public due to Operasi Tangkap Tangan (OTT)/Red-handed Catch Operation to many government officials involved in bribery action, but the subject matter thereof is whether the OTT is in line with the fundamental consideration of KPK founding pursuant to Law Number 30 of 2002 as updated by the Law Number 19 of 2019 in order to increase the eradication of corruption crime causing the state's financial loss with respect to people welfare particularly KPK powers pursuant to the provision of Article 11 thereof, among others, specifying that KPK shall be authorized to conduct inquiry, investigation and prosecution on corruption crime related to the state financial loss of at least Rp 1,000,000,000 but in fact many OTTs performed by KPK have a value of hundred million Rupiah only and even there are any cases below Rp 100,000,000.-, and bribery action control through OTT being more dominant if compared to the state's financial corruption is not in line with the primary consideration of KPK founding, and similarly the OTT below 1 billion Rupiah doesn't conform to the provision of Article 11 thereof.

Modern constitutional transformations, asserting a “value” legal understanding, actualize theoretical and practical problems of legislative regulation, serve as a prereq- uisite for rethinking the essence, role and significance of law in the life of society, and determine the formulation of a number of issues related, first of all, to the qualitative implementation of novelties. This collection reflects the diversity and depth of scientific discussions of the XV In- ternational school of young legal scholars on the topic “Constitution and modernization of legislation”, which was held by the Institute of legislation and comparative law under the Government of the Russian Federation in cooperation with the International Union of lawyers. In the context of a difficult epidemiological situation related to the spread of corona- virus infection, in order to protect the health of conference participants, the organizing Committee decided to hold the XV School remotely (by correspondence). For the first time, all its scientific events were held online. The participants had a unique opportunity to communicate with the direct developers of amendments to the Constitution of the Russian Federation, present their reports in a new format.

Aceh Province is a special area. Acts No. 11 of 2006 concerning theGovernment of Aceh provides freedom in terms of managing the government,especially regarding the implementation of Islamic law in Aceh. Islamic Shari’a isnot only understood as a rule that regulates education, but also about regulation ingovernment management in Aceh. One part of the government is about compilingregional spending in Aceh. This research is focused on budgeting which will becontextualized with Acehnese values, namely the local value of implementingIslamic law in Aceh. Priority indicators for a budget arrangement so that theyfulfill the requirements as ideal budgets according to Islam (Islamic budget ideal).In terms of substance, this research is classified into qualitative research, whichfocuses on the depth and sharpness of the study. So if more quantitative researchis on a broad, broad framework, the qualitative study is digging, swooping, anddeep. Islamic budgeting is a value that in this context wants to be included in thebudget in South Aceh. Based on the results of the study it was found that in terms ofthe determination of post-expenditure it is possible to include the values of IslamicShari’a. In this case the post expenditure is based on maqasid as-Syari’iyah. Interms of revenue, only zakat, shadaqah, and infaq are possible to be contextualized.As for ‘usyr, rikaz, etc., it is not possible because regional revenues from the fiscalside are regulated so rigid in state regulations

Renormalization Group Approach

We generalise the epidemic Renormalization Group framework while connecting it to a SIR model with time-dependent coefficients. We then confront the model with COVID-19 in Denmark, Germany, Italy and France and show that the approach works rather well in reproducing the data. We also show that a better understanding of the time dependence of the recovery rate would require extending the model to take into account the number of deaths whenever these are over 15% of the cumulative number of infected cases.

Data is presented suggesting that rates of L-arabinose transport, calculated from L-[1-14C]arabinose uptake measurements, can be used as indicators of changes in the rates of glucose transport in isolated rat adipocytes. L-[1-14C]arabinose, at 37 degrees C, was found to be nonmetabolizable and taken up by adipocytes exponentially with time reaching 95% of equilibrium in 30 min. When L-arabinose is corrected for background, the corrected uptake values conform to the time-dependent monoexponential uptake relationshiop predicted for a facilitated transport system and are not significantly different from 0 in the presence of 70 micron cytochalasin B. Transport rates were calculated from corrected uptake values near the half-maximal uptake of L-arabinose and from a value of the total amount of L-arabinose in the cell at equilibrium. Competitive inhibition of L-arabinose transport by glucose and countertransport of L-arabinose in the presence of glucose suggest that L-arabinose and glucose share the same transport system. Data is presented demonstrating the effect of insulin and dexamethasone on the transport system that confirms the conclusions obtained by other investigators using other methods.
