Mango (Mangifera indica L.) is one of the choicest tropical fruit of the world and rightly designated as "King" of all fruits. It is a nutritionally important fruit being a good source of vitamin A, B and C and minerals. Post-harvest losses in mangoes have been estimated in the range of 25 to 40% from harvesting to consumption stage. Improved practices and preservation have a great impact on retaining mango fruit quality and on the supply chain. Nowadays food irradiation process is an engrained technology for the preservation of foods and food products. Three different kinds of ionizing radiation are applicable for food irradiation processes (Gamma-rays which is emitted from the radio-isotopes Cobalt-60 and Caesium-137, or electron beams and X-rays). Food irradiation can be considered an evolving technique that is capable of increasing the shelf-life, deferring the ripening and senescence of fruits, and thwart of microorganism activity along with insect infestation. Irradiated food is save for human health. This review article is focusing on irradiation effects on mango and the adoption of improved practices by the farmer for export besides that of food safety.
We examine the long-run relationship between tourism development and economic growth using the Nonlinear Autoregressive Distributed Lag (NARDL) model for Bangladesh using annual data from 1980 to 2016. We find an asymmetric relationship between tourism and Bangladesh's economy since a 1% increase in tourism receipt increases economic growth by about 0.19%. On the contrary, due to a 1% decline in the tourism receipt, economic growth will decrease by about 0.66%. So, the decline in tourism receipt will have a higher negative impact on economic growth than the increase in the tourism receipt in Bangladesh, which result is important for current pandemic situation in tourism due to Covid-19. We also reveal that the impact of positive change in the tourism revenue on GDP stabilizes around 8 years; however, an adverse change on GDP does not stabilize in 15 years. We recommend that a systematic allocation of resources is required to promote and stimulate the tourism industry in Bangladesh for a favourable impact on the country's long-run economic development.
Drug Design, often mentioned as rational drug design or just rational design. It is defined as the study of the shape of molecules in order to determine how they will bind receptors on cells or combine with other molecules. It is based on molecular shape or architecture is an alternative to blindly testing hundreds of molecules to see if one or more of them will bind cellular or molecular targets. The drug is an organic molecule, when it is bind to target site it can either inhibit or activate the function of a bio-molecule which results in therapeutic benefit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
