Com.lexes of La（Ⅲ）, Ce（Ⅲ）, Pr（Ⅲ）, Nd（Ⅲ）, Sm.Ⅲ）, Eu（Ⅲ）, Gd（Ⅲ）, Dy（Ⅲ）, Yb.Ⅲ）, and Lu0ID with 2-（N-o- hydroxyacetophenone）am.no-3-carb.xyethyl-4,5,6,7-tetrahydrob.nzo[b.thiophene （HAAT） form.d b. the condensation of o-hydroxyacetophenone and 2-am.no-3-carb.xyethyl-4,5,6,7-tetrahydrob.nzo[b.thiophene were synthesized and characterized on the b.sis of elem.ntal analyses, m.lar conductance m.asurem.nts, m.gnetic susceptib.lity data, UV-Visib.e, IR, and Nm. spectral studies. The spectral data revealed that the ligand acted as a neutral tridentate coordinating to the m.tal ion through ONO donor sequence. A coordination num.er nine was proposed for the com.lexes. Therm.l decom.osition studies of the ligand and lanthanum.Ⅲ） com.lex were carried out and kinetic param.ters were calculated using Coats-Redfem.equation. The decom.osition reactions followed random.nucleation m.chanism.with one nucleus on each particle.

Com.lete fusion of two selected ceils allows for the creation of novel hyb.id cells with inherited genetic properties from.b.th original cells. Alternatively, via fusion of a selected cell with a selected vesicle, chem.cals or genes can b. directly delivered into the cell of interest, to control cellular reactions or gene expression. Here, we dem.nstrate how to perform.an optically controlled fusion of two selected cells or of one cell and one vesicle. Fusion is m.diated b. laser irradiating plasm.nic gold nanoparticles optically trapped b.tween two cells （or a vesicle and a cell） of interest. This hot-particle-m.diated fusion causes total m.xing of the two cytoplasm. and the two cell m.m.ranes resulting in form.tion of a new hyb.id cell with an intact cell m.m.rane and enzym.tic activity following fusion. Sim.larly, fusion b.tween a vesicle and a cell results in delivery of the vesicle cargo to the cytoplasm. and after fusion, the cell shows signs of viab.lity. The m.thod is an im.lem.ntation of targeted drug delivery at the single-cell level and has a great potential for cellular control and design.

In this paper, we consider an application of hyperstructure theory in b.ological inher- itance in which we deal with n-ary hyperstructures associated to the genotypes of the second generation F2 for n ： 2, 3, 4. First, we define a hyperoperation × （m.ting） on F2 and prove that it is a cyclic Hv-sem.group under the defined hyperoperation. Then we define a ternary hyperstructure f associated to the genotypes of F2 and prove that （F2, f） is a ternary Hv-sem.group. Finally, we define a 4-ary hyperstructure g associated to the genotypes of F2 and prove that （F2, g） is a 4-ary Hv-sem.group.

The evolution of a m.lecular system.excited ab.ve its ionization threshold depends on a num.er of param.ters that include the nature of the excited states and their couplings to the various continua. The general nature of the processes governing this evolution depends also essentially on the com.lexity of the m.lecule, m.re precisely on its size, density of states, and strength of the couplings am.ng the various internal degrees of freedom. In this paper we address the question of the transition b.tween autoionization that prevails in sm.ll m.lecules, and delayed ionization occurring in larger m.lecules or clusters. This transition is illustrated b. autoionization of Na2 Rydb.rg states on one hand, delayed ionization in fullerene C60, and delayed detachm.nt in sm.ll cluster anions on the other hand. All processes are studied in the case of nanosecond laser excitation, corresponding to a rather slow deposition of the internal energy.

Two preselected plant growth prom.ting rhizob.cteria(PGPR) containing 1-am.nocyclopropane-1-carb.xylate(ACC) -deam.nase(EC 4.***.99.4) were used to investigate their potential to am.liorate the effects of drought stress on growth,yield,and ripening of pea(Pisum.sativum.L.) . Inoculated and uninoculated(control) seeds of pea cultivar 2000 were sown in pots(four seeds pot-1) and placed in a wire house. The plants were exposed to drought stress at different stages of growth(vegetative,flowering,and pod form.tion) b. skipping the respective irrigation. Results revealed that inoculation of peas with PGPR containing ACC-deam.nase significantly decreased the "drought stress im.osed effects" on the growth and yield of peas. Exposure of plants to drought stress at vegetative growth stage significantly decreased shoot growth b. 41% in the case of uninoculated plants,whereas,b. only 18% in the case of inoculated plants com.ared to nonstressed uninoculated control. Grain yield was decreased when plants were exposed to drought stress at the flowering and pod form.tion stage,b.t inoculation resulted in b.tter grain yield(up to 62% and 40% higher,respectively) than the respective uninoculated nonstressed control. Ripening of pods was also delayed in plants inoculated with PGPR,which m.y im.ly decreased endogenous ethylene production in inoculated plants. This prem.se is further supported b. the ob.ervation that inoculation with PGPR reduced the intensity of classical "triple" response in etiolated pea seedlings,caused b. externally applied ACC. It is very prob.b.e that the drought stress induced inhib.tory effects of ethylene could b. partially or com.letely elim.nated b. inoculation with PGPR containing ACC-deam.nase.

Coal oxidation at low tem.eratures is the heat source liab.e for the self-heating and spontaneous com.ustion of coal. This phenom.non has im.osed severe prob.em. in coal related industries. Attem.ts to understand this phenom.non b. previous researchers have provided significant progress. It is wellknown that coal oxidation at low tem.eratures involves oxygen consum.tion and form.tion of gaseous and solid oxidation products. This process is m.jorly influenced b. tem.erature, oxidation history of coal,coal properties, particle size distrib.tion of the coal, etc. The current understanding of the phenom.non of self-heating and spontaneous com.ustion of coal is discussed along with the different experim.ntal and num.rical m.dels estab.ished to predict self-heating characteristics of coal. This paper focuses on the glob.l position of the study carried out b. academ.cs, research institutes and industries on spontaneous com.ustion of coal and coal m.ne fires. Within this fram.work, the generally used spontaneous com.ustion techniques to predict the spontaneous com.ustion liab.lity of coal were evaluated. These techniques are well-known in their usage, b.t no specific m.thod has b.com. a standard to predict the spontaneous com.ustion liab.lity. Further study is still needed to indicate a num.er of im.ending issues and to ob.ain a m.re com.lete understanding on the phenom.non.

The first-principles study of the structural, elastic and electronic properties of the m.XC phases depending on the type of m.transition m.tal （m.are Ti and Cr） and on X （X are Ga and A1） was reported. The calculations are perform.d using the pseudo-potential plane-wave approach in b.th the local density and generalized gradient approxim.tions. The elastic constants are calculated using the static finite strain technique. Features such as structural and elastic param.ters, Deb.e tem. perature, sound velocities and their pressure dependence have b.en investigated. In agreem.nt with experim.ntal and previous theoretical findings, it is found that the com.ressib.lity along a and c axis depends on the valence electron concentration （VEC）. Correlations revealing the governing role of the X and m.elem.nts on the m.chinab.lity indices of the m.terial have b.en exam.ned. The electronic properties have b.en discussed in term. of chem.cal b.nding showing that b.nding is due to m.-Cp and m.-Xp hyb.idizations. m.C b.nds are stiffer than m.X ones and A1-Ti （Cr-C） b.nds are stiffer than those corresponding to Ti-C （A1-Cr）. It is shown that the stiffness of the m.X and m.C b.nds increases with increasing the num.er of VEC.

The diurnal activity patterns, trypanosom. infection rates and m.vem.nt of Glossinafuscipesfuscipes （Diptera： Glossinidae） were investigated in b.vum. Island, Lake Victoria, Uganda. Hourly trapping of tsetse flies was undertaken to determ.ne their activity rhythm.while a capture-m.rk-release-recapture m.thod was conducted to assess the m.vem.nt and dispersal of tsetse flies b.tween lakeshore, hinterland and further inland sites along a transected area. Dissection of tsetse flies was also undertaken to determ.ne the trypanosom. infection rates in salivary glands, prob.scis and m.d-gut. Results indicated a b.m.dal diurnal activity profile for G. f fuscipes on the Island, b.th on the lakeshore and in the hinterland. m.vem.nt and dispersal of G. f fuscipes tsetse flies occurred b.tween lakeshore, hinterland and further inland sites with a greater tendency of flies to m.ve to the lakeshore. Trypanosom. infection rates of 4.32% for Trypasom. vivax and 1.15% for 7. congolense were found in G. f. fuscipes.
