Design of need-based phosphors and scintillators by compositional modulation in the ZnGaAlO:Cr spinel: pure compound solid solutions.

Materials that can depict persistent deep red light under both ultraviolet (UV) and X-ray illumination can be a boon to sustainable economy, particularly for optical imaging, solid state lighting, and anticounterfeiting applications. Herein, we have made a series of compounds starting from ZnGaO:Cr to ZnAlO:Cr (individual spinel) by substituting the varied concentration of Al in place of Ga in ZnGaAlO:Cr (solid solution). By virtue of the structural and defect engineering doping strategy, the photo and radioluminescence are expected to be improved.

Tuberculosis of the central nervous system in children.

Background: Central nervous system tuberculosis (CNS TB) in children is still a socioeconomic problem in developing countries. It has varied manifestations, symptoms are nonspecific, diagnosis can be challenging, and treatment may be difficult. It is often missed or overlooked.

Surgical incision by high frequency cautery.

Traditionally, the knife has been used to make surgical incisions on the skin, but recent data suggest that diathermy blade allows the incision to be made more quickly, with less blood loss, less postoperative pain and no adverse effects on wound healing or cosmetic effect.
