Mouse Anti Drosophila kel Hybridoma [lfm 2C]

Single-round demographic surveys of three Malian populations showed substantial fertility differentials, with much lower fertility in the two nomadic pastoral Kel Tamasheq populations than among the sedentary cultivating Bambara. Demographic analysis explained these fertility differentials by different marriage patterns, dominated by the structural effects of Kel Tamasheq monogamy which maintains a large group of currently unmarried women. This contrasts with the Kel Tamasheq's own preoccupations with their low fertility which they ascribe to pathologically induced subfecundity and sterility. Parity progression ratios and birth-interval distributions are used to examine the degree to which the Tamasheq perceptions of their own fertility behaviour can be demonstrated by using the demographic data. The importance of the different perspectives and outcomes is discussed, with the need for taking into account local concerns both in analysis and ultimate policy interventions.

Cesium is a member of the Group I alkali metals, very reactive earth metals that react vigorously with both air and water. The chemistry of cesium is much like the chemistry of neighboring elements on the periodic table, potassium and rubidium. This close relation creates many problems in plant-life exposed to cesium because it is so easily confused for potassium, an essential nutrient to plants. Radioactive (134)Cs and (137)Cs are also chemically akin to potassium and stable cesium. Uptake of these radioactive isotopes from groundwater by plant-life destroys the plant-life and can potentially expose humans to the radioactive affects of (134)Cs and (137)Cs. Much experimental work has been focused on the separation of (137)Cs from uranium fission products. In previous experimental work performed a column consisting of Kel-F supporting tetraphenylboron (TPB) was utilized to separate (137)Cs from uranium fission products. It is of interest at this time to attempt the separation of (134)Cs from 0.01M EDTA using the same method and Neoflon in the place of Kel-F as the inert support. The results of this experiment give a separation efficiency of 88% and show a linear relationship between the column bed length and the separation efficiency obtained.
