Dynamics Of Business And Economics - Global Perspective With Respect To India, During Covid-19 Pandemic

International business encompasses all commercial and economic activities between the nations to promote the transfer the goods and services, ideas, resources and technologies across the national borders. Every country has limited resources therefore a country cannot produce all the goods and services that it requires. The present context of the world, there is imbalance in production and supply factors due to Covid-19, which has led to market imbalances in demand and supply. The world economy has been hit hard by the ongoing Covid-19 pandemic, as on June end more than ten 10 million people around the globe had been affected by disease, USA, India and others are worst hit countries with decrease in GDP and increase in unemployment. It may be useful to also note that prolonged lockdowns will eventually imply production shortfalls, may lead to increase in unemployment; decrease in demand for products, slowly running out stocks. In recent forecast of World Trade Organisation (WTO) indicated a clear fall in world trade between 13 per cent and 32 per cent in 2020, perhaps the highest fall since the Great Depression of 1930s. The purpose of the research paper is Economic and Business crisis, due to covid-19 in present situation in India and the world. India and world can overcome the challenges by specific government, by providing economic relief packages and increase in employment opportunities by digitalisation in all the sectors of the economy to increase in gross production, investment, job security to casual labours. These factors may change the world present situation to productive or welfare economy

Covid-19 And Its Impact On Indian Economy With Respect To Crude Oil

India is one of the largest economy in the world, with population around 1.4 Billion, and average GDP (Gross Domestic product) from 2015- 2019 is around 7 percent, India is the third largest oil importer in the world, with 9.7 percent of the world oil imports, after China and USA, India imports around 80 percent of its oil needs and aims to bring down to 67 percent by 2022, by replacing it by local exploration, renewable energy and indigenous ethanol fuel, but in India there is lack of demand for crude oil and oil products due to Covid-19 epidemic, which made Indian government to imply restrictions, to lockdown of various firms, industries, public and private sector institutions, as health emergency, according to the report of IEA ( International Energy Agency) India’s 40 days lockdown has led to decrease in 30 percent fall in countriesdemandforenergy.Covid-19 is concern for Indian oil producers, as it is the biggest shock since the Second World War,The global economy is expected to enter recessionary Zone in 2020, as countries have shut down there normal business activities, to fight the pandemic led to imbalances in demand and supply of oil prices in the Indian market, Indian oil companies are waiting for the tax reductions and packagesbythegovernment,inthe short term imbalance in oil demand and supply situation. The purpose of the research paper is that, Indian government has a great task to fight against covid-19 as a health emergency and oil prices fluctuations in the year 2020

Search for a W' boson decaying to a bottom quark and a top quark in pp collisions at sqrt(s) = 7 TeV

Results are presented from a search for a W' boson using a dataset corresponding to 5.0 inverse femtobarns of integrated luminosity collected during 2011 by the CMS experiment at the LHC in pp collisions at sqrt(s)=7 TeV. The W' boson is modeled as a heavy W boson, but different scenarios for the couplings to fermions are considered, involving both left-handed and right-handed chiral projections of the fermions, as well as an arbitrary mixture of the two. The search is performed in the decay channel W' to t b, leading to a final state signature with a single lepton (e, mu), missing transverse energy, and jets, at least one of which is tagged as a b-jet. A W' boson that couples to fermions with the same coupling constant as the W, but to the right-handed rather than left-handed chiral projections, is excluded for masses below 1.85 TeV at the 95% confidence level. For the first time using LHC data, constraints on the W' gauge coupling for a set of left- and right-handed coupling combinations have been placed. These results represent a significant improvement over previously published limits.Comment: Submitted to Physics Letters B. Replaced with version publishe

Search for new physics in events with opposite-sign leptons, jets, and missing transverse energy in pp collisions at sqrt(s) = 7 TeV

A search is presented for physics beyond the standard model (BSM) in final states with a pair of opposite-sign isolated leptons accompanied by jets and missing transverse energy. The search uses LHC data recorded at a center-of-mass energy sqrt(s) = 7 TeV with the CMS detector, corresponding to an integrated luminosity of approximately 5 inverse femtobarns. Two complementary search strategies are employed. The first probes models with a specific dilepton production mechanism that leads to a characteristic kinematic edge in the dilepton mass distribution. The second strategy probes models of dilepton production with heavy, colored objects that decay to final states including invisible particles, leading to very large hadronic activity and missing transverse energy. No evidence for an event yield in excess of the standard model expectations is found. Upper limits on the BSM contributions to the signal regions are deduced from the results, which are used to exclude a region of the parameter space of the constrained minimal supersymmetric extension of the standard model. Additional information related to detector efficiencies and response is provided to allow testing specific models of BSM physics not considered in this paper.Comment: Replaced with published version.

Estimating global injuries morbidity and mortality : methods and data used in the Global Burden of Disease 2017 study

Background While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria. Methods In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then estimating incidence for every cause of injury. Non-fatal disability for each cause is then calculated based on the probabilities of suffering from different types of bodily injury experienced. Results GBD 2017 produced morbidity and mortality estimates for 38 causes of injury. Estimates were produced in terms of incidence, prevalence, years lived with disability, cause-specific mortality, years of life lost and disability-adjusted life-years for a 28-year period for 22 age groups, 195 countries and both sexes. Conclusions GBD 2017 demonstrated a complex and sophisticated series of analytical steps using the largest known database of morbidity and mortality data on injuries. GBD 2017 results should be used to help inform injury prevention policy making and resource allocation. We also identify important avenues for improving injury burden estimation in the future.Peer reviewe
