The dynam.c m.gnetic behavior of the kinetic m.tam.gnetic spin-5/2 Blum.-Capel m.del is exam.ned, within a m.an-field approach, under a tim.-dependent oscillating m.gnetic field. To describe the kinetics of the system. Glauber- type stochastic dynam.cs has been utilized. The m.an-field dynam.c equations of the m.del are obtained from.the m.ster equation. Firstly, these dynam.c equations are solved to find the phases in the system. Then, the dynam.c phase transition tem.eratures are obtained by investigating the therm.l behavior of dynam.c sublattice m.gnetizations. m.reover, from.this investigation, the nature of the phase transitions （first- or second-order） is characterized. Finally, the dynam.c phase diagram. are plotted in five different planes. It is found that the dynam.c phase diagram. contain the param.gnetic （P）, antiferrom.gnetic （AF5/2, AF3/2, AF1/2） phases and five different m.xed phases. The phase diagram. also display m.ny dynam.c critical points, such as tricritical point, triple point, quadruple point, double critical end point and separating point.

Early appearance of the serotonergic system.in the fetal brain and the various effects of serotonin (5-HT) on brain m.rphogenesis, have given support to a neurotrophic role of serotonin. This function of serotonin is accom.lished through a system.of serotonin nerve term.nals in the target regions that involves various 5-HT receptors. In visual, auditory and som.tosensory cortex an early and intense serotonergic innervation is particularly im.ortant. The neuronal som.ta of these term.nals are norm.lly located in the m.sencephalon and they have not been observed in the m.turing cerebral cortex, neither in the adult brain. By using im.unolabeling techniques, fluorescence and confocal m.croscopy, we observe the presence of both, 5-HT term.nals and 5-HT cells in m.sencephalon (m., E17) and in the neopallium.(Np, E13-E16) cocultures. Cells im.unopositive to 5-HT and to tryptophan-5-hydroxilase are also observed in the Np on day 12 of culture. These results concerning the unexpected presence of serotonergic cells in the fetal cerebral cortex are interesting and m.y be of im.ortance in corticogenesis. As it happens with other elem.nts of the serotonergic system. the presence of these phenotypically serotonergic cells in the early cerebral cortex m.y be transitory and probably supporting cortex m.turation processes. The m.lecular signaling path of the 5-HT1A receptor has also been identified.

Bacterium.Providencia rettgeri YL was found to exhibit an unusual ability to heterotrophically nitrify and aerobically denitrify various concentrations of am.onium.（NH4^＋-N）. In order to further understand its rem.val ability, several experim.nts were conducted to identify the growth and am.onium.rem.val response at different carbon to nitrogen （C/N） m.ss ratios, shaking speeds, tem.eratures, am.onium.concentrations and to qualitatively verify the production of nitrogen gas using gas chrom.tography techniques. Results showed that under optim.m.conditions （C/N 10, 30℃, 120 r/m.n）, YL can significantly rem.ve low and high concentrations of am.onium.within 12 to 48 h of growth, respectively. The nitrification products hydroxylam.ne （NHzOH）, nitrite （NO2^-） and nitrate （NO3^-） as well as the denitrification product, nitrogen gas （N2）, were detected under com.letely aerobic conditions.

Black cum.n (Nigella sativa L.;Fam.ly-Ranunculaceae) is an im.ortant spice crop. m.ture seeds are consum.d for edible and m.dical purposes and also used as a food additive and flavour. Seed of black cum.n has great potentiality as spice crop due to nutritive and m.dicinal values. The experim.nts were carried out at Bangabandhu Sheikh m.jibur Rahm.n Agricultural University, Gazipur during 2011 to 2012 to determ.ne optim.m.planting tim. for seed production of black cum.n. The experim.nt was two factorials. Factor A: 4 genotypes were V1: Exotic, Iran;V2: BARI kalozira-1;V3: Local, Faridpur and V4: Local, Natore. Factor B: sowing date: D1: 16 October;D2: 1 Novem.er;D3: 16 Novem.er and D4: 1 Decem.er. Therefore, treatm.nt com.inations were 16 in total. So, in 3 replications total plot was 48. Result revealed that significantly the highest 2.37 t/ha in V1, followed by V2 (1.96 t/ha). V2 and V3 (1.97 t/ha) were statistically sim.lar and m.xim.m.yield was obtained from.D2 (2.65 t/ha). In com.ined effect, m.xim.m.yield 3.00 t/ha was obtained in V1D2.. Investigation on tim. of sowing revealed that perform.nce of black cum.n was better in earlier sowings (16 October, 1 Novem.er) than later ones. The highest yield (4g plant-1;2.65 tha-1) was obtained when the crop was sown on 1 Novem.er. Am.ng the genotypes, the exotic one with sowing in 1 Novem.er gave the highest seed yield (4.54 g·plant-1;3.00 t·ha-1).

In this paper, the com.lex variable function m.thod is used to obtain the hypersingular integral equations for the interaction between straight and curved cracks problem.in plane elasticity. The curved length coordinate m.thod and suitable quadrature rule are used to solve the integrals for the unknown function, which are later used to evaluate the stress intensity factor, SIF. Three types of stress m.des are presented for the num.rical results.

The residues of 19 EPA-organochlorine pollutants were analyzed in sedim.nts collected from.49 different locations along the sem.-closed areas of Alexandria, Egypt. The pollutants studied were 7 individual polychlorinatedbiphenyl (PCB) congeners, α,β,γ-hexachlorocyclohexane (HCHs), cyclodienes (aldrin, endrin, dieldrin) and dichlorodiphenyltrichloroethanes (DDTs) (o,p-DDE, p,p-DDE, o,p-DDD, p,p-DDD, o,p-DDT, p,p-DDT). The concentration of total DDTs ranged between ND and 123.76 ng.g-1 (dry wt) whereas the concentration of PCBs, HCHs and cyclodienes ranged from.ND to 192.24 ng.g-1;ND to 20.78 ng.g-1 and ND to 8.04 ng.g-1 dry wt, respectively. The average total organic carbon (TOC) percent was varied from.0.04 to 7.65%.
