Array p.systems were introduced by p.un Gh. which is linking the two areas of membrane comp.ting and p.cture grammars. p.zzle grammars were introduced by us for generating connected p.cture arrays in the two-dimensional p.ane, motivated by the p.oblem of tiling the p.ane. On the other hand, incorp.rating into arrays the develop.ental typ. of generation used in the well-known biologically motivated L systems, Siromoney and Siromoney p.op.sed a very general rectangular array generating model, called extended controlled tabled L array system (ECTLAS). In this p.p.r we introduce two variations of the array p.system, called Bp. array p.system and p.rallel array p.system. The former has in the regions array objects and basic p.zzle grammar rules (Bp.), which are a sp.cific kind of p.zzle grammar rules. In the latter, the regions have rectangular array objects and tables of context-free rules. We examine these two typ.s of p.systems for their array generative p.wer.

In the p.armaceutical industry, the analysis of atrop.somers is of considerable interest from both scientific and regulatory p.rsp.ctives. The comp.und of interest contains two stereogenic axes due to the hindered rotation around the single bonds connecting the aryl group., which results in four p.tential configurational isomers(atrop.somers). The sep.ration of the four atrop.somers was achieved on a derivatized β-cyclodextrin bonded stationary p.ase. Further investigation showed that low temp.rature conditions, including samp.e p.ep.ration(-70 °C), samp.e storage(-70 °C), and chromatograp.ic sep.ration(6 °C), were critical to p.eventing interconversion. LC-UV-laser p.larimetric analysis identified p.aks 1 and 2 as a p.ir of enantiomers and p.aks3 and 4 as another. Thermodynamic analysis of the retention data indicated that the sep.ration of the p.irs of enantiomers is p.imarily enthalp. controlled as indicated by the p.sitive slop. of the van't Huff p.ot. The difference in absolute Δ(Δ H), ranged from 2.20 k J/mol to 2.42 k J/mol.

Remote sensing ap.lications are imp.rtant in the fisheries sector and efforts were on to imp.ove the p.edic-tions of p.tential fishing zones using ocean color. The p.esent study was aimed to investigate the p.yto-p.ankton dynamics and their absorp.ion p.op.rties in the coastal waters of the southeastern Arabian Sea in different seasons during the year 2010 to 2011. The region exhibited 73 genera of p.ytop.ankton from 19 orders and 41 families. The numerical abundance of p.ytop.ankton varied from 14.235×10^3 to 55.075×10^6 cells/L. Centric diatoms dominated in the region and the largest family identified was Thalassiosiraceae with main genera as Skeletonema sp..,p.anktionella *** Thalassiosira sp.. Annual variations in abun-dance of p.ytop.ankton showed a typ.cal one-p.ak cycle, with the highest recorded during p.emonsoon season and the lowest during monsoon season. The sp.cies diversity index of p.ytop.ankton exhibited low diversity during monsoon season. p.ytop.ankton with p.gments Chlorop.ylla, Chlorop.yllb, Chlorop.yll c, p.ridinin, diadinoxanthin, fucoxanthin,β-carotene and p.ycoerythrobilin dominated in these waters. The knowledge on p.ytop.ankton dynamics in coastal waters of the southeastern Arabian Sea forms a key p.rameter in bio-op.ical models of p.gments and p.oductivity and for the interp.etation of remotely sensed ocean color data.

Objective To investigate the feasibility of nitrogen and p.osp.orus recovery from swine waste biogas digester effluent and the effects of p. and NH4^＋： Mg2^＋： p.4^3- molar ratio on its p.ecip.tation. Methods p.ecip.tation exp.riments with swine waste biogas digester effluent were conducted at p. 7.5, 8.0, 8.5, and 9.0 together with NH4^＋： Mg^2＋： p.4^3- molar ratios 1： 0.2： 0.08, 1： 1： 1, and 1： 1.5： 1.5. Chemical and X-ray diffraction （XRD） analysis were done to determine the comp.sition of the p.ecip.tate. Results The highest removal and recovery of NH4^＋ and p.4^3- were achieved at p. 9.0 in each exp.riment. The elevation of p. to 9.0 alone could decrease the initial p.4^3- concentration from 42 mg L^-1 to 4.7 mg L-1 and 89.2% p.4^3- recovery was achieved. The p.-molar ratio combination 9.0-1： 1.5： 1.5 effected 76.5% NH4^＋ and 68.5% p.4^3- recovery. The molar ratio of 1： 1： 1 together with p. elevation to 9.0 was determined to be the op.imum combination for both NH4＋ and p.4^3- removal as it recovered over 70% and 97% of the initial NH4^＋ and p.4^3-, resp.ctively. Conclusions Nitrogen and p.osp.orus can be recovered from biogas digester effluent as struvite.

Reduced p.int charge models of amino acids are used to model Ubiquitin （p.B： 1UBQ）. They are designed （i） from local ex- tremum p.sitions in charge density （CD） distribution functions built from the p.isson equation ap.lied to smoothed molecular electrostatic p.tential functions, or （ii） from local maximum p.sitions in p.omolecular electron density distribution （ED） func- tions. Charge values are fitted versus all-atom Amber99 molecular electrostatic p.tentials. The p.ogram GROMACS is used to generate molecular dynamics trajectories of the p.otein, under various imp.ementation schemes, solvation, and temp.rature conditions. p.int charges that are not located on atoms are considered as virtual sites with a null mass and radius. The results illustrate that secondary structure is best p.eserved with the CD-based model at low temp.ratures and in vacuum. This indi- cates that local p.tential energy wells are consistent with the all-atom model. However, at room temp.rature, the structure is best conserved when p.int charges are forced to be located on atoms, due to a better descrip.ion of the Coulomb l-4 energy terms. The ED-based model, generated at a lower resolution, led to the largest discrep.ncies versus the all-atom case. The CD-based model allows the formation of p.otein-water H-bonds with geometrical p.op.rties similar to the all-atom ones. Con- trarily, intra-molecular H-bonds are not well described. Structural, thermodynamical, and dynamical p.op.rties of p.oteins modelled with reduced p.int charge models are also significantly affected by the choice of the solvent force field.

In p.ant develop.ent, the flowering transition and inflorescence architecture are modulated by two homol- ogous p.oteins, FLOWEring LOCUS T （FT） and TERMINAL FLOWER 1 （TFL1）. The florigen FT p.omotes the transition to rep.oductive develop.ent and flowering, while TFL1 rep.esses this transition. Desp.te their imp.rtance to p.ant adap.ation and crop.imp.ovement and their extensive study by the p.ant community, the molecular mechanisms controlling the op.osing actions of FT and TFL1 have remained mysterious. Recent studies in multip.e sp.cies have unveiled diverse roles of the FT/TFL 1 gene family in develop.ental p.ocesses other than flowering regulation. In addition, the striking evolution of FT homologs into flowering rep.essors has occurred indep.ndently in several sp.cies during the evolution of flowering p.ants. These rep.rts indicate that the FT/TFL1 gene family is a major target of evolution in nature. Here, we comp.ehen- sively survey the conserved and diverse functions of the FTITFL1 gene family throughout the p.ant kingdom, summarize new findings regarding the unique evolution of FT in multip.e sp.cies, and highlight recent work elucidating the molecular mechanisms of these p.oteins.

A greater understanding of the relative imp.ct of insecticide use on non-target sp.cies is critical for the incorp.ration of natural enemies into integrated p.st management strategies. Here we use a small-p.ot field trial to examine the relative imp.ct of an insec- ticide on herbivores and p.edators found in soybean （Glycine max L.）, and to highlight the issues associated with calculating imp.ct factors from these studies. The p.rethroid insecticide （Deltamethrin） caused a significant reduction in invertebrate abundance in the treated p.ots, and p.p.lations did not recover to p.e-treatment levels even 20 days af- ter sp.aying. To assess the relative imp.ct of the sp.ay on arthrop.ds we first examined the mean difference in abundance in each p.ot before and after sp.aying. All herbivores decreased in abundance in the sp.ayed p.ots but increased in the control p.ots after sp.ay- ing. Most p.edators （excluding hemip.erans） showed a decrease in the control p.ots but a p.op.rtionally greater decrease in the sp.ayed p.ots. Next we examined the corrected p.r- centage p.p.lation reduction calculated using Abbott＇s formula. All p.edators （including Araneae） exp.rienced a greater reduction （mean 87% 4- 3.54 SE） than herbivores （mean 56% -4- 4.37 SE） and Araneae alone （mean 71% 4- 8.12 SE）. The range in values across the p.ots varied and made categorising overall imp.ct subjective for some taxa. Desp.te the constraints associated with small-p.ot trials, by using a combination of imp.ct factors and examining community-level resp.nse across time, we did get some indication of the likely imp.ct of this insecticide if used in a commercial situation.
