Review on grain size effects on thermal conductivity in ZnO thermoelectric materials.

Thermoelectric materials have recently attracted a lot of attention due to their ability to convert waste heat into electricity. Based on the extensive research in this area, the nanostructuring approach has been viewed as an effective strategy for increasing thermoelectric performance. This approach focuses on the formation and growth of the superfine, pure and uniform grain size.

Effect of rifampin with bio-enhancer in the treatment of newly diagnosed sputum positive pulmonary tuberculosis patients: A double-center study.

Objective: To compare a fixed-dose combination (FDC) of Rifampicin 450 mg, Isoniazid 300 mg, Pyrazinamide 1500 mg and Ethambutol 800 mg (usual care group) and regimen of Rifampicin 200 mg, Isoniazid 300 mg and piperine 10 mg along with Pyrazinamide 1500 mg and Ethambutol 800 mg (intervention care group).

Methods: A randomized, prospective, parallel group study was conducted on newly diagnosed tuberculosis patients. The drugs were given during intensive and continuous phase of treatment to newly diagnosed sputum positive pulmonary tuberculosis.
