As the most efficient way of connecting distributed generations which are mainly based on renewable resources to the power grid, the microgrid has been in fast development in recent years. The paper is based on the summary of the present situation of research on microgrid all over the world and the key technology urgently to be solved, and then the advantage and the necessity of developing DC microgrid is analysed in terms of components as well as operation and control of microgrid. At last, an AC/DC hybrid microgrid structure is proposed according to the present circumstances in the distribution network.

Invasive species, those that are nonnative and cause economic damage, are one of the main threats to ecosystems around the world. Ambrosia beetles are some of the most common invasive insects. Currently, severe economic impacts have been increasingly reported for all the invasive shot hole borers in South Africa, California, Israel, and throughout Asia. This 7-page fact sheet written by Demian F. Gomez, Jiri Hulcr, and Daniel Carrillo and published by the School of Forest Resources and Conservation describes shot hole borers and their biology and hosts and lists some strategies for prevention and control of these pests. http://edis.ifas.ufl.edu/fr422

Dengue fever is a painful mosquito-borne infection caused by different types of virus in various localities of the world. There is no particular medicine or vaccine to treat person suffering from dengue fever. Dengue viruses are transmitted by the bite of female Aedes (Ae) mosquitoes. Dengue fever viruses are mainly transmitted by Aedes which can be active in tropical or subtropical climates. Aedes Aegypti is the key step to avoid infection transmission to save millions of people in all over the world. This paper provides a standard guideline in the planning of dengue prevention and control measures. At the same time gives the priorities including clinical management and hospitalized dengue patients have to address essentially.

A novel spillover coronavirus (nCoV), with its epicenter in Wuhan, China's People's Republic, has emerged as an international public health emergency. This began as an outbreak in December 2019, and till November eighth, 2020, there have been 8.5 million affirmed instances of novel Covid disease2019 (COVID-19) in India, with 1,26,611 deaths, resulting in an overall case fatality rate of 1.48 percent. Coronavirus clinical signs are fundamentally the same as those of other respiratory infections. In different parts of the world, the quantity of research center affirmed cases and related passings are rising consistently. The COVID- 19 is an arising pandemic-responsible viral infection. Coronavirus has influenced huge parts of the total populace, which has prompted a global general wellbeing crisis, setting all health associations on high attentive. This review sums up the overall landmass, virology, pathogenesis, the study of disease transmission, clinical introduction, determination, treatment, and control of COVID-19 with the reference to India.

Since the birth of 5G, it has attracted much attention from all countries in the world. The development of 5G industry is particularly important for domestic economic development. 4G changes life, 5G changes society. 5G will not only accelerate the speed of people surfing the Internet, but also bring revolutionary changes to all aspects of social life, making people's lives, work and entertainment more convenient and diverse. The economic impact of the development of the 5G industry on China cannot be underestimated. Nowadays, information and communication technology has increasingly become a new driving force for economic development. 5G technology has already become a key technology pursuit for countries to compete for the status of world power, and it has also become an indispensable part of contemporary economic and social development. We should give full play to the government's guiding role, and work with network giants to build a new platform for cooperation, promote coordinated industrial development, achieve win-win results, and promote economic and social prosperity and development.

The formation of external policy of any country aims at serving the state’s interests. For this matter, many countries seek their way through this by taking into account the potential prospects available to them. The fundamental subtleties and factors that influence a state’s choices of external policy include geographical location, history, security, culture, trade, political ideology, military might, et cetera. Countries often make external contacts based on some regulations and response to unfolding events. Thus, external policy to an extent pertains to the guiding principles outlined to be pursued through state values, decisions and actions taken by the states themselves and their attempt to develop, manage and control the external relations of national societies. In this regard, the Caucasian region has been an important factor in Turkey’s foreign policy. Since these states emerged in the early 1990s, energy has taken a center stage within the region, while Turkey remains a transit route to the world...

In vision of searching for the right Unmanned Aerial System (UAS) for a specific mission, there are multiple factors to be considered by the operator such as mission, endurance, type of payload and range of the telemetry and control. This research is focusing on extending control range of the UAS by using 4G-LTE network to enable beyond-line-of-sight flying for the commercial UAS. Major UAS such Global Hawk, Predator MQ-1 are able to fly thousands of kilometers by the use of satellite communication. However, the satellite communication annual license subscription can be very expensive. With this situation in mind, a new type of flight controller with 4G-LTE communication has been developed and tested. Throughout the research, blended-wing-body (BWB) Baseline B2S is used as the platform for technology demonstrator. Result from this analysis has proven that the proposed system is capable to control a UAS from as far as United Kingdom, with a latency less than 881 ms in average. The new added capability can potentially give the commercial UAS community a new horizon to be able to control their UAS from anywhere around the world with the availability of 4G-LTE connection

Present Context

International business is essential for the countries to generate Economic growth or to increase in exports and reduce in imports, it encompasses all commercial and economic activities between the nations to promote the ideas, resources, transfer the goods and services, technologies across the national borders. In 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 pandemic, which has resulted in market imbalances (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 this pandemic, India, USA and others are worst hit countries with decrease in GDP (Gross Domestic Product) and increase in unemployment rate. 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. India and world can overcome the challenges by specific government fiscal and monetary policies, by providing economic relief packages and increase in employment opportunities by digitalisation in all the sectors of the economy to increase in accountability, convenience, and gross production, and investment, job security to casual labours or migrant workers. These factors may change the world present situation to productive or welfare economy. The purpose of the research paper is to explain Economic and Business crisis, due to covid-19 in present situation in India and the world. KEY WORDS: C0VID-19, GDP, ECONOMY and GLOBAL CRISIS.
