Investigation of an Impedimetric LaSrMnO-Au/YO-ZrO-AlO Composite NO Sensor.

Composite NO sensors were fabricated by combining partially and fully stabilized yttria-doped zirconia with alumina forming a composite electrolyte, YO-ZrO-AlO, and strontium-doped lanthanum manganese oxide mixed with gold to form the composite sensing electrode, La SrMnO-Au. A surface chemistry analysis of the composite sensor was conducted to interpret defects and the structural phases present at the YO-ZrO-AlO electrolyte, as well as the charge conduction mechanism at the LaSrMnO-Au electrode surface. Based on the surface chemistry analysis, ionic and electronic transport properties, and microstructural features of sensor components, the working principle was described for NO sensing at the composite sensor.

Incidence of the Hb E [β26(B8)Glu→Lys, GAG>AAG] variant in Totos, one of the smallest primitive tribes in the world.

Toto is one of the smallest tribes in the world. This primitive sub Himalayan, endogamous tribe lives in a small, isolated village called Totopara in the Jalpaiguri district of West Bengal in India. The tribal communities of West Bengal are vulnerable to various genetic disorders such as β-thalassemia (β-thal).
