متن کاملKojic Acid Derivatives
Melanin is one of the most important pigments which exist ubiquitously from microorganisms to plants and animals. It is secreted by melanocyte cells and determines the color of skin and hair in mammalians. It protects the skin from photocarcinogenesis by absorbing UV sunlight and removing reactive oxygen species (ROS) (Gupta, 2006; Kim, 2005; Sapkota, 2011). It is formed by enzymatically cataly...
متن کاملHigh resolution mass spectrometry.
Over the past decade, mass spectrometry has been revolutionized by access to instruments of increasingly high mass-resolving power. For small molecules up to approximately 400 Da (e.g., drugs, metabolites, and various natural organic mixtures ranging from foods to petroleum), it is possible to determine elemental compositions (C(c)H(h)N(n)O(o)S(s)P(p)...) of thousands of chemical components sim...
متن کاملthe impact of musical texts on the text recall of young learners of english in isfahan junior high schools
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
15 صفحه اولHigh Resolution FTIR Spectrum of Chlorofluoroethyne
High resolution infrared spectra of FCCC1 have been measured and analyzed by polynomial methods. In the region below 350 c m 1 , the analysis is straightforward and yields parameters for the V4 = 1 and = 1 states. Between 350 and 800 c m 1 there are strong anharmonic interactions in the 2v5/u4 + u^lu^llu^ tetrad which have been unravelled with the use of a model that employs ab initio interacti...
