Mobile Phone Technologies

Mobile Phone Technologies 1G Technology The development of 1G mobile phones took place in late 1970s. The 1G mobile devices sent only the “analogue voice information” via amplitude modulation (AM), which varies the amplitude of the carrier signal, and frequency modulation (FM), which changes the Frequency of the career signal. In electronics, the analog signal devices were followed by Analog to Digital convertors. The most important 1G system were Advanced Mo

Odisha’s first case of harlequin ichthyosis

Odisha’s first case of harlequin ichthyosis WHY? Mutations in the ABCA 12 gene are stated to cause harlequin ichthyosis. The ABCA12 protein plays a major role in transporting fats in cells which make up the outermost layer of skin. Severe mutations in the gene lead to the absence or partial production of the ABCA12 protein. This results in lack of lipid transport and as a result, the skin development is affected by varying degrees according to the severity of the mutation, a doc
