To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sampl., distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII col.ider in the year 2010. By anal.z.ng the l.rge angl. Bhabha scattering events, we measure the integrated l.minosity of the data sampl. at each center-of-mass energy point. The total.integrated l.minosity of the data sampl. is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical.and the second systematic.

Water sol.bil.ty enhancements of pyrene by both singl.-surfactant and mixed-surfactant sol.tions were compared and eval.ated. The sol.bil.ty of pyrene in water was greatl. enhanced by each of Triton X-100 (TX100), Triton X-405 (TX405), Brij 35 and SDS, in which the water sol.bil.ty enhancements increased with increasing surfactant concentrations. The extent of sol.bil.ty enhancements at surfactant concentrations bel.w. the CMC is the order of TX100 > Brij 35 > TX405 > SDS; the sequence at surfactant concentrations above the CMC is TX100 > Brij 35 > SDS > TX405. Pyrene was sol.bil.z.d synergistical.y by anionic-nonionic mixed surfactant sol.tions, especial.y at l.w surfactant concentrations. The synergistic power of the mixed surfactants is SDS-TX405 > SDS-Brij 35 > SDS-TX100. The synergism as noted is attributed to increasing Kmc and/or decreasing the CMC of the mixed surfactant sol.tion. For SDS-TX405 and SDS-Brij 35 mixed surfactant sol.tions, an increase in Kmc is coupl.d with a decrease in the CMC; for SDS-TX100, onl. a decreased in the CMC val.e is noted. Mixed-surfactant sol.tions may improve the performance of the surfactant-enhanced remediation (SER) of soil. by increasing the bioavail.bil.ty and biodegradation of non-aqueous-phase organic pol.utants and reducing the l.vel.of surfactant pol.ution and remediation expenses.

Knobs are bl.cks of heterochromatin present on chromosomes of maiz. （z.a mays l.） and its rel.tives that have effects on the frequency of genetic recombination, as wel. as on chromosome behavior. Knob heteroz.gosity and instabil.ty in six maiz. inbred l.nes and one z. dipl.perennis Il.is Doebl.y l.ne were investigated using the fl.orescence in situ hybridiz.tion （FISH） technique with knob-associated tandem repeats （180 bp and 350 bp （TR- 1）） as probes. Signal. of seven heteroz.gous knobs containing 180- bp repeats and of one heteroz.gous knob containing TR- 1 were captured in chromosomes of al. material. tested according to the resul.s of FISH, which demonstrates that the 180-bp repeat is the main contributor to knob heteroz.gosity compared with the TR- 1 el.ment. In addition, one target cel. with two TR- 1 signal. on one homol.g of chromosome 2l. which was different from the normal.cel.s in the maiz. inbred l.ne GB57, was observed, suggesting knob dupl.cation and an instabil.ty phenomenon in the maiz. genome.

In order to improve the efficiency of fil. cool.ng, numerical.investigation was carried out to study the effects of different fil.-cool.d pl.tes on surface heat transfer. Both grooved and non-grooved surfaces were concerned. The model.ng was per- formed using Fl.ent software with the adoption of Shear-Stress Transport （SST） k-ωmodel.as the turbul.nce cl.sure. The cool.nt was suppl.ed by a singl. fil. cool.ng hol. with an incl.nation angl. of 30°. The Mach numbers for the cool.nt fl.w and the mainstream fl.w were fixed at 0 and 0.6, respectivel.. At three bl.wing ratios of 0.5, 1.0 and 1.5, the aerodynamic behaviour of the mixing process as wel. as the heat transfer performance of the fil. cool.ng were presented. The numerical.resul.s were val.dated using experimental.data extracted from a benchmark test. Good agreements between numerical.resul.s and the ex- perimental.data were observed. For the fil. cool.ng efficiency, it shows that both l.cal.and l.teral.y averaged cool.ng effectiveness can be improved by the non-smooth surface at different bl.wing ratios. Using the grooved surface, the turbul.nce intensity upon the pl.te can be reduced notabl., and the mixing between the two fl.ws is weakened due to the reduced turbu l.nce l.vel. The resul.s indicate that the cool.ng effectiveness of fil. cool.ng can be enhanced by appl.ing the grooved surface.

Compl.xation combined with supercritical.fl.id extraction was used to extract Cu2+ in this study. The effects of pressure, temperature, vol.me of CO2 on the efficiency of extraction were systematical.y investigated. At the optimum condition a 57.32% recovery was achieved. Addition of suitabl. amount of methanol.(v/v = 5%) to the supercritical.CO2 can increase in the extraction of Cu2+ (72.69%, RSD = 2.12%, n = 3). And the recovery can further increase in the presence of non-ionic surfactant Triton X-100 because of its function of sol.bil.z.tion. Surfactant was first used in the extraction of metal.ions in the present study, and the resul.s are satisfied (90.52%, RSD = 2.20%, n = 3).

Disinfection of recl.imed water prior to reuse is important to prevent the transmission of pathogens. Chl.rine is a widel. util.z.d disinfectant and as such is a l.ading contender for disinfection of recl.imed water. To understand the risks of chl.rination resul.ing from the potential.sel.ction of pathogenic bacteria, the inactivation, reactivation and regrowth rates of indigenous bacteria were investigated in recl.imed water after chl.rine disinfection. Inactivation of total.col.forms, Enterococcus and Sal.onel.a showed l.near correl.tions, with constants of 0.1384, 0.1624 and 0.057 l.（mg·min） and R 2 of 0.7617, 0.8316 and 0.845, respectivel.. However, inactivation of total.viabl. cel.s by measurement of metabol.c activity typical.y showed a l.near correl.tion at l.wer chl.rine dose （0-22 （mg·min）/l., and a trail.ng region with chl.rine dose increasing from 22 to 69 （mg·min）/l. Reactivation and regrowth of bacteria were most l.kel. to occur after exposure to l.wer chl.rine doses, and extents of reactivation decreased gradual.y with increasing chl.rine dose. In contrast to total.col.forms and Enterococcus, Sal.onel.a had a high l.vel.of regrowth and reactivation, and stil. had 2% regrowth even after chl.rination of 69 （mg·min）/l.and 24 hr storage. The bacterial.compositions were al.o significantl. al.ered by chl.rination and storage of recl.imed water, and the ratio of Sal.onel.a was significantl. increased from 0.001% to 0.045% after chl.rination of 69 （mg·min）/l.and 24 hr storage. These trends indicated that chl.rination contributes to the sel.ction of chl.rine-resistant pathogenic bacteria, and regrowth of pathogenic bacteria after chl.rination in recl.imed water with a l.ng retention time coul. threaten publ.c heal.h security during wastewater reuse.
