Life has evolved on Earth for about 4 billion years in the presence of the natural background of ionizing radiation.It is extremely likely that it contributed, and still contributes, to shaping present form of life.Today the natural background radiation is extremely small (few mSv/y), however it may be significant enough for living organisms to res
Birds exhibit a specialized tail that serves as an integral part of the flight mercury metallic lexus apparatus, supplementing the role of the wings in facilitating high performance aerial locomotion.The evolution of this function for the tail contributed to the diversification of birds by allowing them to utilize a wider range of flight behaviors
The objective of this paper is to present an extended approach to address the stochastic multi-attribute decision-making problem.The novelty of this study is to consider the regret behavior of decision mercury metallic lexus makers under a Pythagorean hesitant fuzzy environment.First, the group satisfaction degree of decision-making matrices is use
Background: The 5326058hx filler addition to resin based sealers will enhance the physical properties of the polymer.Because of its biological properties, the synthetic hydroxyapatite (HA) has been proposed as filler for dental material such as composite resin.The calcite synthesized HA is the HA produced of calcite minerals that came from many Ind
