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.

Biodegradable polymers have become one of the major discussable matters and considered as the most viable alternative to the traditional plastic materials among the researchers in the modern world. To keep the environmental issues in mind, innovation of environment-friendly products for our daily usage the utilization of degradable materials is increasing at a high rate. The modern world wants sustainable products which will not bring about any harm to the environment. Most of the common sustainable products are made from plastics but the main drawback of using these products is they are resistant to degradation which is a great threat to our environment. After the end of our usage, this material can sustain for a long time without any degradation which causes a supreme level of loss to our environment. The materials which are not biodegradable cause great pollution especially soil pollution. So, to protect the environment from the ruthless ridicule of pollution it has become a crying need for us to use biodegradable materials as a viable alternative to plastics. As a result, researchers are investing their time into modifying the biodegradable materials incorporated with the most common being starch and fiber extracted from various types of plants that can be easily degraded in the environment. Biodegradable materials contain almost all the properties which are suitable for our environment. Already these materials have been using in several sectors and showing their applications for their friendly properties. This paper focused on the properties and application area of biodegradable properties in detail.

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.
