background : due to rapid advances in modern technologies such as telecommunication technology, the world has witnessed an exponential growth in the use of digital handheld devices (e.g. smartphones and tablets). this drastic growth has resulted in increased global concerns about the safety of these devices. smartphones, tablets, laptops, and other digital screens emit high levels of short-wave...

Proto-acting is introduced here as a new concept that refers to a set of processes that are intermediate between everyday role playing (in the Erving Goffman sense) and dramatic acting. Its most characteristic process is the voluntary act of personal mimicry, which can occur in everyday contexts, such as quoting someone during conversation, or in performance contexts, such as impressionism. Pro...

The purpose of this research was to develop fast dissolving tablets of olanzapine and to optimize the processing variables. Tablets containing olanzapine, camphor, crosscarmellose, and directly compressible lactose were prepared by direct compression technique. The tablets were compressed and later exposed to vacuum. Sublimation of camphor from tablets resulted in superior fast dissolving table...

Based on the presumed capability of a prebiotic pocket-like entity to accommodate substrates whose stereochemistry enables the creation of chemical bonds, it is suggested that a universal symmetrical region identified within all contemporary ribosomes originated from an entity that we term the 'proto-ribosome'. This 'proto-ribosome' could have evolved from an earlier machine that was capable of...

Ever since the Afroasiatic affiliation of Chadic as a whole was suggested by Joseph H. Greenberg in his seminal re-classification African languages 1950s and has been generally accepted, i.e. encompassing both ‘Chado-Hamitic’ ‘Chadic’ influential pre-Greenbergian genetic classifications, issue whether Proto-Chadic possessed prenasalised obstruents velar nasals repeatedly raised debated literatu...

the aim of this study is to prepare novel sorbitol based extended release tablets by melt dispersion method using carbamazepine as a model drug. carbamazepine was melted along with sugar alcohol to get melt dispersion granules (mgds) and was characterized by differential scanning calorimetry (dsc), powder x-ray diffractometry (xrd) and solubility study. the physical and chemical parameters of m...
