Ecological engineering plays an increasingly significant role in mountain hazard control, but the effect of species selection and arrangement(e.g., row spacing and stem spacing) on debris flow suppression is still unclear. To further understand the interception efficiency of shrub arrangement parameters on debris flow and explore the difference with slow hydraulic erosion, sixteen sets of small-scale flume experiments with different stem and row spacings were done to study the effects of shrubs on debris flow severity, flow rate, velocity, and particle size. The results suggest that, for a dilute debris flow, sediment interception effectiveness(27.4%-60.9%) decreases gradually as stem spacing increases. Moreover, as row spacing increases, flow velocity reduction(34.4%-44.9%) and flow reduction(18.5%-47.4%) gradually decrease; and the bulk density reduction(0.5%-5.3%) and sediment interception increase initially and then decrease. In contrast, for a viscous debris flow, the flow reduction, flow velocity reduction, and sedimentation interception decrease gradually as the stem spacing increases. As row spacing increases,the flow velocity reduction, flow reduction, and sediment interception all increase initially and then decrease. A formula for the flow velocity of dilute debris flow after the filter strip was derived based on the energy conservation law and Bernoulli’s equation, confirming that debris flow movement is closely related to the degree of vegetation cover. This research strengthens the current understanding of the effectiveness of vegetation in debris flow disaster prevention and control and can guide practical applications.

Status and Citizenship Rights of Minorities and Coexistence in Islam

引用

Journal of Philosophy Study 2012年第7期2卷 488-501页

作者： ali akbar alikhani University of Tehran

the more attention is paid to rights of minorities, the more grounds will be there for peaceful coexistence. This paper will first discuss theoretical and ideological bases of status and citizenship rights of minorities before focusing on ＂citizenship status of minorities＂ and ＂citizenship rights of minorities＂ from the viewpoint of Islam. Islam here means the collection of Quran, Prophet Muhammad＇s （S） Sunnah, and Imam ali＇s （AS） conduct. The main question of this paper is ＂what status and rights have been considered by Islam for minorities to allow peaceful coexistence in a Muslim society？＂＂Minority＂ here includes both religious and non-religious minorities. ＂Rights＂ here means that part of ＂assets,＂＂means,＂＂political and social leverages,＂＂privileges,＂ and ＂conditions＂ which the majority is bound to by law, religious and common sense to provide for minorities. The word ＂status＂ here means to respect, serve, and provide suitable conditions which are provided just out of respect for human values not due to legal compulsion. In this paper, we will first discuss theoretical and ideological fundaments of minorities＇ rights before discussing ＂citizenship status of minorities＂ and ＂citizenship rights of minorities＂ from the viewpoint of Islam. By Islam, we mean Quran as well as Sunnah of Prophet Muhammad （S） and conduct of Imam All （AS）.

IRON DETERMINATION AFTER ON-LINE SORBENT PRECONCENTRATION BY FI-FASS USING 1,10-PHENANTHROLINE AS A COMPLEXING AGENT

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2000年第1期1卷 11-17页

作者： akbar ali 叶映雪徐光明张涛殷学锋金鑫 Dept. of ChemistryYuquan Campus of Zhejiang UniversityHangzhouChina Zhejiang Environmental Monitoring CentreHangzhouChina

Phenanthroline (phen) was tested as a complexing agent for on line preconcentration of iron on RP C\-\{18\} material in a microcolumn with flow injection coupled with flame atomic absorption spectrometer (FI FAAS). The on line formed Fe(II) phen complexes were adsorbed on the C\-\{18\} sorbent material. Various parameters affecting the on line Fe(II) phen complex formation and its subsequent adsorption in the microcolumn as well as its elution into the nebulizer of AAS were optimized. A 2.5×10\+\{-3\} mol/L phen in 2% ethanol was on line mixed with aqueous sample solution acidified with 0.1% (v/v) HCl and allowed to flow through the microcolumn for 30 s. The adsorbed Fe(II) phen complexes in the microcolumn were eluted with ethanol in 10 s into the nebulizer of AAS. Ascorbic acid (5×10\+\{-4\} mol/L) was added to the sample solution for the reduction of Fe(III) to Fe(II). A good precision (RSD=1.1%, \%n\%=10), high enrichment factor (19) and sample throughput (90 h\+\{-1\}) with detection limit (3σ) of 3 μg/L were obtained. The method was applied on standard reference materials(i.e. mussel and tomato leaves,) for iron determination and yielded results agreeing well with certified values.
