All isocyanide adducts maintain close metal-metal contacts in the solid state.Researchers are taking great interest in the synthesis and characterization of MnZn ferrites due to their wide range of applications in many areas. MnZn ferrites are a class of soft magnetic materials that have very good electrical, magnetic and optical properties. The properties of MnZn ferrites include high value of resistivity, permeability, permittivity, saturation magnetization, low power losses and coercivity. The above mentioned advantageous features of MnZn ferrites make them suitable for the use in various applications. In biomedical field these ferrites are used for cancer treatment and MRI. MnZn ferrites are also used in electronic applications for making transformers, transducers and inductors. These ferrites are also used in magnetic fluids, sensors and biosensors. MnZn ferrite is highly useful material for several electrical and electronic applications. It finds applications in almost every household appliances like mobile charger, LED bulb, TV, refrigerator, juicer mixer, washing machine, iron, microwave oven, mobile, laptop, desktop, printer and so on. Therefore, the present review focuses on different techniques for synthesis of MnZn ferrites in literature, their characterization tools, effect of doping on the properties of MnZn ferrite and finally we will discuss about their applications. © 2020 Elsevier Ltd and Techna Group S.r.l.

They are found to be stably present in diverse body fluids, including those in the circulatory system, which can be sampled non-invasively for clinical tests. Thus, circulating ncRNAs have great potential to be disease biomarkers. However, tremendous efforts are desired to discover and utilize ncRNAs as biomarkers in clinical diagnosis, calling for technological advancement in analysis of circulating ncRNAs in biospecimens. Hence, this review summarizes the recent developments in this area, highlighting the works devoted to cancer diagnosis and prognosis. Three main directions are focused 1) Extraction and purification of ncRNAs from body fluids; 2) Quantification of the purified circulating ncRNAs; and 3) Microfluidic platforms for integration of both steps to enable point-of-care diagnostics. These technologies have laid a solid foundation to move forward the applications of circulating ncRNAs in disease diagnosis and cure.We propose a DSGE model to examine the impact of the coronavirus outbreak on tourism.•The model is generalizable to any epidemic.•The model supports the policy of providing tourism consumption vouchers for residents. © 2020 Elsevier Ltd.

Moreover, those that have been published, focus on subsets of FDI. This review systematically examines the empirical as well as theoretical research on FDI through an analysis of 500 articles published during the last five decades. Theoretical models, methods, context, and contributions to scholarship were reviewed. We strive to highlight the key theories, paradigms, and articles and provide directions for future research. We conclude that FDI has evolved as the most significant area of international business. © 2020 Elsevier Inc.

This is a call for the R&D community, particularly in the polymer degradation and stability arena, to engage and collaborate with virology and bio-medical experts. We require comparative R&D for extended, reuse and recyclability options, as well as large scale approaches and methods that could quickly be applied on the local level by the public who are not experts and may only have limited resources. © 2020 Published by Elsevier Ltd.The People's Republic of China increasingly has turned to political warfare and sharp power to influence U.S. Liraglutide policy toward China and on international issues that it considers important. This turn in part reflects the limited effectiveness of Beijing's much-increased hard power and its never-formidable and now-reduced soft power as means to achieve China's ends with the United States. China's political warfare and uses of sharp power pursue both direct influence on U.S. policy and indirect impact through affecting American attitudes toward China and China-related issues. China's efforts range across many sectors-including business, culture, media, education, and more-and they have prompted reactions and countermeasures. In China's view, the United States has long been engaged in something like political warfare or sharp power undertakings targeting China. If, or as, U.S.-China relations continue to become more adversarial, political warfare, uses of sharp power, and measures to counter them are likely to increase. .The election of Tsai Ing-wen as President of the Republic of China (Taiwan) in 2016 reignited Beijing's quest to poach Taiwan's diplomatic allies. Between her election in January 2016 and reelection in January 2020, Taiwan has lost seven countries to China. After eight years of a "diplomatic truce" under President Ma Ying-jeou, China re-started its multi-pronged strategy to pressure Taiwan into eventual unification, and one of the key tactics is to poach all of Taiwan's now-15 remaining diplomatic allies to eliminate its international legitimacy. This article seeks to explain what, if any, benefits formal diplomatic relations provide Taiwan and the ways in which Beijing induces countries to switch ties. It concludes by providing recommendations for what actions the United States can undertake to slow the impending completion of the "race to zero." .In December 2019 a new human coronavirus emerged in Wuhan, China, which is known as SARS-CoV‑2. The clinical course of the disease known as coronavirus disease 2019 (COVID-19) ranges from mild respiratory symptoms to severe lung failure. The virus is currently rapidly spreading around the world and pushing health systems to the limits of their capacity due to the exponential increase in the number of cases. The origin of SARS-CoV‑2 lies in the bat coronavirus pool and has now emerged in the human population due to interspecies transmission. Molecular diagnostic methods have been established in a very short time and a number of clinical studies on the effectiveness of different antiviral drugs are ongoing. The development of a vaccine using different approaches is also under investigation.Considering the high number of cases and mortality rates of up to 9% there is an urgent need for action. This article summarizes the current state of knowledge on human coronaviruses with a strong focus on the current data on SARS-CoV‑2.
