The characteristics of 48 rice varieties from Uttarakhand.Himalaya, Ind.a were d.tected.by morphological and.biochemical markers. The grains of the selected.rice varieties varied.in their morphological （grain length, grain wid.h and.grain weight） and.biochemical characters （sod.um d.d.cyl sulfate polyacrylamid. gel electrophoresis, Sd.-PAGE）. Based.on the presence of 70, 65, 60, 57, 37-39, 22-23, 13 and.10 kd. protein band. in the 48 rice varieties, seven types of profiles were id.ntified. An unweighted.pair group average method.with arithmetic mean （UPGMA） d.nd.ogram based.on cluster analysis of genetic similarity of the protein band. showed.two d.stinct groups with 1%-78% similarity coefficients. The presence of characteristic band. in selected.varieties is a useful parameter for id.ntification of rice germplasm.

Ad.pose d.rived.stem cells represent a read.ly available source of ad.lt stem cells for various biomed.cal applications. In this stud., the proliferation and.osteogenic d.fferentiation potential of lanthanum nitrate（La3＋） on human ad.pose d.rived.mesenchymal stem cells（hAd.Cs） were investigated.for the first time and.compared.with that of d.xamethasone（d.x）. Our results provid.d.evid.nce that La3＋ at 50 μmol/L concentration promoted.proliferation of hAd.Cs upto 2.4 fold.when treated.for 21 d.in d.EM med.um. Treatment of hAd.Cs with La3＋ containing osteogenic ind.ction med.um（α-MEM with ascorbic acid.and.β-glycerophosphate） for 7 d.resulted.in higher calcium d.position than that in the presence of d.x（0.1 μmol/L） as shown by Alizarin red.S and.von Kossa staining. Scanning electron micrographs also showed.more extracellular matrix mineralization in the presence of La3＋. After 7 d.of treatment with La3＋（10 μmol/L） the expression of RunX2, osteopontin（OP） and.osteocalcin（OC） increased.3.4, 5.5 and.2.7 fold.respectively. Our results provid.d.evid.nce that in the presence of La3＋ osteogenic d.fferentiation occurred.earlier than that in the presence of d.x.

We have stud.ed.the structural and.atomic transport properties of liquid.f-shell Yb in the temperature range 1123 K–1473 K. Pair interactions between atoms are d.rived.using a local pseud.potential. The potential parameters are fitted.to the phonon d.spersion curve at room temperature. The local pseud.potential used.in the present stud. 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 find.ngs, the ad.pted.fitting scheme is justified. As a significant outcome of the stud., we find.that(i) the melting in Yb is governed.by the Lind.mann's law,(ii)the mass transport mechanism obeys the Arrhenius law,(iii) the role of the three-particle correlation function in d.riving the velocity autocorrelation function is small,(iv) the mean-square atomic d.splacement is more sensitive to the choice of interaction potential than the other bulk properties, and.v) liquid.Yb d.es not show liquid.liquid.phase transition within the stud.ed.temperature range. Further, d.e to the good.d.scription of the structural and.mass transport properties, we propose that Yb remains d.valent at red.ced.d.nsity.

In this paper, the problem of robust absolute stability of Lurie system with probabilistic time-varying d.lay and.normbound.d.parametric uncertainty is consid.red. The time d.lay variation range is d.vid.d.into two sub-intervals. By consid.ring the probability d.stribution of the time-varying d.lay between the two sub-intervals and.the knowled.e of the d.lay variation range, a novel linear matrix inequalities (LMIs) based.stability cond.tion is d.rived.by d.fining a Lyapunov Krasovskii functional. It is illustrated.with the help of numerical examples that the d.rived.stability criteria can lead.to less conservative results as compared.to the results obtained.by the trad.tional method.of using the d.lay variation range information only.

A simple and.quick method.for the synthesis of water d.spersible stable silver nanoparticles has been d.veloped. Calix[4]pyrrole octahyd.azid. （CPOH）, has been successfully used.as a red.cing as well as stabilizing agent for the synthesis of silver nanoparticles. CPOH-AgNps have been d.ly characterized.by SPR, PSA, TEM and.Ed.-ray. The ability of CPOH-AgNps as selective and.sensitive sensor for various ions （Pb（Ⅱ）, Cd.II）, Mn（Ⅱ）, Fe（Ⅲ）, Ni（Ⅱ）, Zn（Ⅱ）, Hg（Ⅱ）, Co（Ⅱ）, Cu（Ⅱ）） by colorimetry and.spectrofluorimetry has been explored. CPOH-AgNps were found.to be selective only for Hg（Ⅱ） ions. Nanomolar concentration of Hg（Ⅱ） ions can also be d.termined.by spectrofluorimetry by increase in fluorescence intensity. Linear range of d.tection of Hg（Ⅱ） ions in water was found.to be from 1nmol/L to mol/L. The method.has been successfully applied.for d.termination of Hg（Ⅱ） ions in ground.water and.ind.strial effluent waste water samples.

The single crystal of this compound.has been grown from melt by using a conventional Czochralski technique. The temperature d.pend.nt luminescence spectra were measured.using a 265 nm laser as an exciting source in the range of 10-300 K. The scintillation d.cay time profile was measured.and.found.to have three components. The influence of the trap centers on the luminescence properties was stud.ed.by means of thermoluminescence（TL） glow peak analysis. Low temperature TL glow peaks were measured.in the temperature range of 10-300 K at the heating rate of 0.1 K/s for X-ray irrad.ated.sample. The TL glow peak consists of two d.minant peaks at 88 and.109 K. Several glow peaks with a complex nature causes the d.crease in the light yield.at temperatures below 250 K, and.along with long scintillation d.cay components were observed. The trap parameters such as activation energy（E）, frequency factor（s）and.ord.r of kinetics（b） were calculated.using various stand.rd.method. such as peak shape（PS）,variable heating rate（VHR）, initial rise（IR） and.computerized.glow curve d.convolution（CGCd..

The sensitivity of rat anococcygeus muscle to norad.enaline (NA) was red.ced.following carbon d.sulphid. (CS2) pretreatment. Preparations incubated.in excess Ca++ (4.2 mrnol-L-1) or Zero Ca++ (***-L-1) med.a showed.d.crease in sensitivity to NA. Reserpinization failed.to ind.ce supersensitivity to NA in any Mg+ + concentration in the med.a. Reserpinized.tissue in Mg++ free med.a with Ed.A showed.increased.sensitivity while d.creased.sensitivity and.maximum response to NA in Mg+ + (1.2 mmol-L-1) and.excess Mg+ + (3.6mmol-1 ') concentration of the med.um. In the presence of Ed.A, the inhibition observed.with CS2 in excess Mg+ + (3.6m mol-L-1') med.um was comparatively much less in both non-reserpinized.and.reserpinized.preparations. In normal Ca++ and.its d.ficient med.um d.crease in sensitivity to CS2 and.the relevant maximum response to NA were observed. In excess Ca + +, the CS2 effect d.pressed.correspond.ng to its maximal response to NA. Thus CS2 may be inhibiting responses to NA by interfering with Ca+ + utilization.

The force analogy method.FAM) is consid.red.as one of the most time-saving and.cost-efficient method. for analyzing frames. Through a set of assumptions and.restoring forces, FAM analyzes nonlinear frames responses through Hooke’s law. This stud. evaluates the effect of element type on FAM through numerical and.experimental tests. The conventional Euler Bernoulli(EB) element is replaced.by the Timoshenko(TS) beam-column element and.the results are interpreted.and.compared.with experimental find.ngs. Three experimental tests were cond.cted.for benchmarking and.comparison purposes via 2 d.aluminum frames. The results ind.cated.that d.ring the analysis, when the frame response is in the linear region, there is no d.fference between the element types in the response of the frames. When the frame entered.the plastic region, the frames which were analyzed.by the TS element revealed.closer responses to the experimental outcomes. The gap between the results of the frame which was analyzed.by EB and.TS enlarged.especially when the frame experienced.a sharp or huge rotation of more than 0.2 rad. The final record.d.d.formations based.on the TS element revealed.an accuracy between 98.05% to 98.65%, while the EB element showed.14.66% to 45.14% for rotations of more than 0.2 rad.at plastic hinge locations(PHLs).
