Self-checking impurity method in liquids
Full text linkWe propose a very simple technique for the determination of impurity in liquids based on the refractive index. This technique requires two similar gratings, two similar low power lasers emitting same wavelength and a position detector. The change in refractive index of liquid determines the impurity in a liquid
Science: An All Encompassing Field
Full text linkWhat unites science, as Sir David Cox mentioned, is not the subject matter we all work in, but the methodology and the thought process that help solve the problems that arise [1]. Put differently, it is the replicability of its methods, the validity of its findings and reliability of its instruments and techniques. The diversity in science now emphasizes that not a single subject matter will work alone in isolation - especially if you are working in applied sciences, but has to learn from others. Even so, contemporary applied sciences have extended this collaboration to the social sciences [2]. For instance, in implementation science they have learnt to involve social sciences to inform human behaviour if scaling-up of interventions is to be a success
