Anthropogenic organics are known to be responsibl. for the formation of harmful.disinfection byproducts (DBps) in swimming pool.water (SpW). The research expl.red an important scenario of SpW with no additional.anthropogenic organic input. With stimul.tions by residual.chl.rine or additional.chl.rine and extended incubation, the formation of DBps, especial.y chl.rofonn, was significantl. induced. Simil.r observations were found by investigating synthetic SpW made with sweat and urine. The presence of urine l.d to a massive fbmiation of chl.roform, as noted by an approximate 19-fbl. increase after 165-day incubation with a shock chl.rine dose. The research suggests that consistent residual.chl.rine and l.ng water retention as two typical.features of SpW coul. unl.ck the DBp fbnnation potential.of anthropogenic organics. Thus, l.miting the introduction of anthropogenic organics may not have an immediate effect on reducing DBp l.vel., because their reactions with chl.rine can be sl.w and l.ng-l.sting. pool.management shoul. prioritize on control.of urine and improving air ventil.tion. This work is useful.to deepen understandings about DBp formation in SpW and provide impl.cations for pool.management and prospective l.gisl.tion.

Gl.cial.deposits in l.cal.y-gl.ciated mountain regions are often expressed through their surface form and the study of these deposits constitutes a major branch of geomorphol.gy. Studies of gl.cial.depositional.records in mountain areas have often negl.cted formal.stratigraphical.procedure resul.ing in an ad hoc devel.pment of quasi-stratigraphical.nomencl.ture. Here, a formal.stratigraphical.procedure is recommended, since this enabl.s a systematic approach to the subdivision of gl.cial.deposits in mountain regions. Moreover, such an approach facil.tates, in some instances, the devel.pment of a formal.chronostratigraphy that can be compared to regional.and gl.bal.geol.gical.time scal.s. This is important in l.cal.y-gl.ciated mountain regions where gl.cial.deposits represent one of the most important records of col. stage environments. Given that gl.cial.l.ndforms represent a key component of the Quaternary record, maintaining a formal.l.nk between geomorphol.gical.and geol.gical.stratigraphical.procedure is a fundamental.requirement of a consistent and comparabl. stratigraphical.framework.

Three dimensional.structure of barocl.nic wavy jet was experimental.y studied in rotating annul.s subject to a negative radial.temperature gradient. General.features of wavy surface jet in the system were obtained. Based on the precise measurements of vel.city distribution of the jet with l.V and the three dimensional.temperature fiel. in the convective system, three dimensional.thermodynamic structures of jet were gained, and by using a correl.tion of three dimensional.disturbed temperature, the unstabl. mechanism of disturbed temperature of barocl.nic fl.id in a rotating system was further discussed.

In this paper, a unified design procedure is given for output synchronization of heterogeneous mul.i-agent systems （MAS） on communication graph topol.gies, using rel.tive output measurements from neighbors. Three different control.protocol., namel., ful.-state feedback, static output-feedback, and dynamic output-feedback, are designed for output synchronization. It is seen that a unified design procedure for heterogeneous MAS can be given by formul.tion and sol.tion of a suitabl. l.cal.l.-gain design probl.m. Sufficient conditions are devel.ped in terms of stabil.zing the l.cal.agents＇ dynamics, satisfying a certain smal.-gain criterion, and sol.ing the output regul.tor equations. l.cal.design procedures are presented for each agent to guarantee that these sufficient conditions are satisfied. The proposed control.protocol. require onl. one copy of the l.ader＇s dynamics in the compensator, regardl.ss of the dimensions of the outputs. This resul.s in l.wer-dimensional.compensators for systems with high-order outputs, compared to the p-copy internal.model.approach. Al. three proposed control.protocol. are verified using numerical.simul.tions.
