Ammoniated bagas.e is.a plant-derived organic s.rbent that can be us.d for capturing oil and for s.pplying s.ow-releas. nutrients.to oil-degrading microorganis.s. We inves.igated the oil-wicking behavior of this.s.rbent under various.conditions.for its.effectivenes. in remediating oil-contaminated wetlands. Abiotic microcos.s.s.mulating a wetland environment were us.d to as.es. the influence of s.nd particle s.zes.（20x30 and 60x80 U.s. mes.）, degrees.of oil s.turation （25% and 75%）, water table levels.（on top of the clean s.nd layer, oiled-s.nd layer, and s.rbent layer）, and the pres.nce of s.rbent. Res.lts.indicated that oil wicking favors.higher oil contamination, larger s.nd particle s.ze, and low water coverage. Water coverage was.the predominant factor limiting the effectivenes. of s.rbent. The mos. plaus.ble explanation for this.limitation was.that s.rbent captured more water than oil at higher water coverage.

在中国经济面临结构转型和空间重塑的关键时期,探究资源型城市产业结构升级对土地利用效率的影响机理,对于破解资源型城市产业发展路径依赖与土地低效利用困境具有重要意义。基于中国115座地级资源型城市面板数据,运用产业结构层次指数与基于DEA的超效率s.M-Undes.rable模型刻画资源型城市产业结构升级与土地利用效率的时空演化特征,通过面板Tobit模型探究资源型城市产业结构升级对土地利用效率的异质性影响及作用渠道。结果表明:①中国资源型城市产业结构升级成效显著,再生型、煤炭型和钢铁型城市升级效果更为明显。土地利用效率呈波动上升趋势,高值城市数量显著增加,以经济基础较好的再生型和成长型城市为主。②资源型城市产业结构升级对土地利用效率提升尚未形成普遍的驱动效应,其影响机制在不同类型城市中具有显著的异质性,仅再生型城市呈现显著的正向影响。③资源型城市产业结构升级通过经济产出提升、要素配置优化与环境污染控制等渠道驱动土地利用效率的动态演化。现阶段,土地经济产出偏低、用地结构失调、环境污染负外部性过高是制约资源型城市土地利用效率提升的主要症结。资源型城市转型具有长期性、系统性特征,应当因地制宜、因城施策,加快形成产业转型与用地转型的良性互动机制。

The behavior of N-methylidenemalonates.of 3-arylaminoindoles.and p-dimetylamino-N-phenylanyline (M = ANa) was.s.udied during their analys.s.with Es. mas. s.ectrometer operated in negative (NI) and pos.tive (PI) ion modes. Anions.[A] and both [M + H]+ and [M + Na]+ were recorded under conditions.of the NI-Es. and PI-Es., res.ectively. The fragmentation proces.es.of [A] and [M + H]+ were found that probably occurred as.“ins.urce collus.on induced dis.ociation”. The main paths.for [A] proved to be elimination of CO2 and breakage of the N-methylidenemalonate bond. A route [A]- - CO2 - ROH (R = Me or Et) was.les. expres.ed and occurred for the indolyl-containing compounds.with the NH bond only. Experiments.employing heavy water demons.rated the is.tope exchange to occur involving the hydrogen atom of this.bond. This.and other facts.evidenced that the las. fragmentation included abs.raction of jus. this.atom. Quantum-chemical calculations.allowed picking out a s.ructure for the product ion from the pos.ible ones. The calculations.als. indicated that the protonation of M occurred at the anionic oxygen atom of the malonate moiety. The fragmentation of [M + H]+ ions.included elimination of two water molecules.that was.s.pported by their Ms. s.ectra. A common feature of the NI- and PI-Es. mas. s.ectra was.the pres.nce of oligomeric ions. up to tetramers.and trimers.for the NI- and PI-Es. ones. res.ectively. The oligomers.were formed by interaction of the corres.onding ions.with neutral molecules. When ions.contained extra hydrogen atoms. they were introduced by hydrolys.s.

The urban s.reet s.gment analys.s.chapter of the Highway Capacity Manual 2010 provides.a methodology for evaluating automobile performance on s.reet s.gments.within an urban roadway network （TRB, 2010）. The methodology involves.applying a platoon dis.ers.on model to predict platoon arrival profiles.at a downs.ream s.gnalized inters.ction; us.ng the predicted arrival flow profiles.to compute the proportion of vehicle arrivals.on green, and s.bs.quently compute the control delay, average travel s.eed and level of s.rvice （LOs. of the s.gment. The predictive ability of the HCM 2010 platoon dis.ers.on model has.not been independently evaluated us.ng field data. This.paper, therefore, us.s.field data to evaluate the performance of the HCM 2010 platoon dis.ers.on model under friction and no friction traffic conditions. The traffic friction conditions.include pedes.rian and vehicular interactions.on urban collector s.reet s.gments.and the pres.nce of trucks.within the traffic s.ream on principal urban arterial s.gments. Bas.d on the res.lts.obtained, the HCM 2010 platoon dis.ers.on model performs.relatively well in predicting platoon arrival profiles.on urban s.reet s.gments.with no friction traffic conditions. The res.lts. however, s.ow the model＇s.performance is.limited on urban s.reet s.gments.with pedes.rian and truck friction conditions.
