TiO2-SiO2 core-shell particles include of monodisperse silica core and nanostructured titania shell were synthesized by a multi-step coating process. The monodisperse silica spheres were synthesized by Stöber method and titania shell was obtained of a colloidal sol prepared by a hydrolysis–condensation reaction. The titania sol was deposited on monodisperse silica spheres by a multi-step coatin...

Behavioral interactions between coexisting species may reflect underlying ecological interactions or may arise from factors unrelated to ecological interactions between species. We examined behavioral interactions between two coexisting, migratory wood warblers that competitively interact on breeding territories in central Arizona, USA. The larger Orange-crowned Warbler (Vermivora celata) is ag...

The performance of photocatalytic advanced oxidation must be improved in order for the technology to make jump from academic research widespread use. Research is needed on factors that cause photocatalysis become self-limiting. In this study, we introduced, first time, nanobubbles continuously into a running reactor. Synthetic air, O2, and N2 bubbles size range 40 700 nm were added reaction sys...

in this research work, we report a simple method called reflux condensation method for synthesizing co3o4 nanoparticles using cheap chemicals such as, cobalt acetate (precursor salt), sodium monododecyl sulphate - sds (surfactant) and n, n - dimethylformamide - dmf (solvent). the prepared materials were heat treated at 200, 400, 600 and 800 oc for each 2 h to get phase pure product. the calcine...

Hypoxia is a potential threat to various horticultural cropsin lands prone to flooding. Citrus is mostly known as a sub-tropical crop that is often exposed to environmental stresses. In order to evaluate response of six different citrus genotypes, including sour orange, rough lemon, Trifoliate orange, Troyer citrange and two local genotypes labeled; CRC1 and CRC2 to flooding conditions, an expe...

Two new species of the genus Katha Moore, 1878 are described from China: pratti sp. n. (Hubei Province) and portokaloftera (Sichuan Province). Both characterised by large size unusual, orange body wings colouration in both sexes. The diagnostic comparison is made with suffusa (Leech, 1899), nigropoda (Bremer & Grey, 1852), magnata (Matsumura, 1927). Adults, male female genitalia all conside...

he noticed a slight enlargement in the left axilla, but as it caused no inconvenience, lie thought no inoreabout it. About a fortnight ago it began to swell very rapidly without any apparent cause, and in the course of a week became as large as an orange. This sudden increase in the size of the tumour caused great anxiety in the family, and the child was brought to the dispensary for out-door r...
