We have studied the structural and atomic transport properties of liquid f-shell Yb in the temperature range 1123 K–1473 K. Pair interactions between atoms are derived using a local pseudopotential. The potential parameters are fitted to the phonon dispersion curve at room temperature. The local pseudopotential used in the present study is computationally more efficient with only three parameters, and it is found to be transferable to the liquid phase without changing the *** the various computed properties agree with reported theoretical and experimental findings, the adopted fitting scheme is justified. As a significant outcome of the study, we find that(i) the melting in Yb is governed by the Lindemann's law,(ii)the mass transport mechanism obeys the Arrhenius law,(iii) the role of the three-particle correlation function in deriving the velocity autocorrelation function is small,(iv) the mean-square atomic displacement is more sensitive to the choice of interaction potential than the other bulk properties, and(v) liquid Yb does not show liquid–liquid phase transition within the studied temperature range. Further, due to the good description of the structural and mass transport properties, we propose that Yb remains divalent at reduced density.

A series of competitive metal-ion transport experiments has been performed. Each involved transport from an aqueous source phase across an organic membrane phase into an aqueous receiving phase. The source phase contained equimolar concentration of Co（ii）, ni（ii）, Zn（ii）, Cd（ii）, Ag（I）, Cu（ii） and Mn（ii） metal cations. The transport experiments of metal cations were carried out by 2,21-dithio（bis）benzothiazole （DTB） in chloroform （CHCl3）. The source phase being buffered at range pH of 4-6.5 and receiving phase being buffered at pH 3. The obtained results show that the selectivity and the efficiency of AgO） transport from aqueous solutions are observed in this investigation. The effect of concentration of palmitic acid in the transport efficiency of Ag（I） ion was also conformed.

MHC class I and ii molecules bind peptides that are either recognized as self or as foreign to the immune system via interaction with T-cell *** T-cell receptor makes molecular contacts with the peptide and the MHC molecule in the region of the MHC peptide binding *** MHC class I and ii molecules are highly polymorphic,which presumably allows for great diversity of antigen-binding sites over the population,leading to a species that is relatively fit to withstand foreign *** MHC class I molecules,this allelic variation predicts extensive variation in the sequence of peptides able to bind MHC class I molecules,and this is indeed the case.

Toxicity-data of two carbamate insecticides, carbaryl and carbofuran, and three fungicides, ziram, zineb and mancozeb with rice-field n2-fixing cyanobacterium Cylindrospermum sp., obtained by in vitro growth and at soil-water interface, were analyzed by the probit method. Growth enhancing concentration, no-observed effective concentration, minimum inhibitory concentration, the highest permissive concentration and lethal concentration100 （LCloo） were determined experimentally. The LC^o values of carbaryl, carbofuran, ziram, zineb and mancozeb in n2-fixing liquid medium were 56.2, 588.8, 0.07, 4.2 and 3.4 IJg/mL, respectively, whereas the corresponding LCloo values were 100.0, 1500.0, 0.17, 25.0 and 9.0 IJg/mL, respectively. The LC50 values of these pesticides in succession in n2-fixing agar medium were 44.7, 239.9, 0.07, 1.8 and 2.3 IJg/mL, respectively, whereas the corresponding LC100 values were 100.0, 600.0, 0.17, 10.0 and 7.0 IJg/mL, respectively. Similar results with nitrate supplemented liquid and agar media indicated that nitrate supplementation had toxicity reducing effect. The LCso and LC^oo values of toxicity in the n2-fixing liquid medium at soil-water interface were 91.2 and 200.0 IJg/mL for carbaryl, 2 317 and 6 000 pg/mL for carbofuran, 0.15 and 0.50 pg/mL for ziram, 16.4 and 50.0 pg/mL for zineb, and 7.2 and 25.0 pg/mL for mancozeb, respectively. Each LC^oo value at soil- water interface with a pesticide was significantly higher than its corresponding LCloo value at liquid/agar media. It can be concluded that, under the n2-fixing conditions, the cyanobacterium tolerated higher levels of each pesticide at soil-water interface.
