Adding the Al-dopant to the Zinc Oxide crystal structure results in changes that affect the optical and nonlinear characteristics. Presented results indicate that the magnitude of X<sup>(3)</sup> was enhanced at single experimental wavelengths;however, across the broadband experimental spectrum, the effect of Al-doping remained relatively constant. The observed enhancement of third-order nonlinearity was purely from the bound electronic response. The observation is attributed to increased charge carriers and spontaneous polarization in the Zinc Oxide and Al-doped Zinc Oxide crystal structure.展开更多

[ Method] Using mi- crosatellite markers （ISSR） molecular maker technology, combined with bulked-segregant analysis （BSA） method, the molecular makers for gene linkage with re- sistance against S. trifoliorum were screened from five resistant plants and seven susceptible plants. Leaf in vitro inoculation method was used to carry out resistant verification on 94 hybrid plants in Ft generation of high resistant No. 83 ~ high susceptible No. 4. [ Result] Among 93 ISSR primers, 35 primers could produce clear and stable amplification bands, and six of them could produce 9 specific bands between resistant and susceptible DNA pools. Resistance verification result showed that 825 - 1400, 831 - 1480, 850 - 1800, 858 - 1600, 866 - 1900, 888 - 1400 could be used as ISSR molecular makers of the resistant gene against S. trifoliorum in M. sativa. [Conclusion] The results provided basis for the further research on mapping,, cloning and genetically modified of resistant gene against S. trifoliorum in M. sativa.展开更多

These settlements represent the fast growing urban areas often dwelling in unplanned and unsecured tenure. Access to safe water supply has great influence on the health, economic productivity and quality of life of the people. But meeting this need is one of the major challenges facing the urban communities of Nigeria today. A field survey was conducted in the area with 100 observations of households in each of the three informal settlements. These settlements are Sabongari -University village, Vinikilang and Wuro Jabbe. The survey solicited for response concerning household water source, water per capita use and household size. Findings revealed that about 92% of respondent in Sabongari-University village, 66% in Vinikilang and 87% in Wuro Jabbe depend on vended water from borehole, hand dug well as well as surface water sources which are delivered by hand pushed trucks. Owing to the absence of piped water networks in the study area, households are forced to rely on available water sources which are precursor to water borne diseases. It is advocated that the public agencies should evolve special programs for regularizing informal settlements, meaning the legalization of land tenure, layout corrections and service upgrading if service is to meet the poor informal dwellers.展开更多
