Commercial grade weakly basic resin D301 was impregnated with iron through a simple method using ferric chloride. Experiments for single, bisolute and trinary competitive adsorption were carried out to investigate the adsorption behavior of 2-naphthalenesulfonic acid(NSA), sulfuric acid and sulfurous acid from their solution at 298 K onto the novel hybrid iron impregnated D301(Fe-D301). Adsorption affinity of NSA on Fe-D301 was found to be much higher than that of sulfuric acid, while adsorption affinity of sulfuric acid was slightly higher than that of sulfurous acid. The data of single-solute adsorption were fitted to the Langmuir model and the Freundlich adsorption model. The non-ideal competitive adsorbed model coupled with the single-solute adsorption models were used to predict the bisolute and trinary-solute competitive adsorption equilibria. The NICM coupled with the Langmuir model yields the favorable representation of the bisolute and trinary-solute competitive adsorption behavior.

AIM: To examine the effects of pancreatic rest, stimulation and rest/stimulation on the natural course of recovery after acute pancreatitis. METHODS: Acute hemorrhagic pancreatitis(AP) was induced in male rats by intraductal infusion of 40 μl/100 g body weight of 3% sodium taurocholate. All rats took food ad libitum. At 24 h after induction of AP, rats were divided into four groups: control(AP-C), pancreas rest(AP-R), stimulation(AP-S), and rest/stimulation(AP-R/S). Rats in the AP-C, AP-R and AP-S groups received oral administration of 2 ml/kg body weight saline, cholecystokinin(CCK)-1 receptor antagonist, and endogenous CCK release stimulant, respectively, twice daily for 10 d, while those in the AP-R/S group received twice daily CCK-1 receptor antagonist for the first 5 d followed by twice daily CCK release stimulant for 5 d. Rats without any treatment were used as control group(Control). Biochemical andhistological changes in the pancreas, and secretory function were evaluated on day 12 at 24 h after the last treatment. RESULTS: Feeding ad libitum(AP-C) delayed biochemical, histological and functional recovery from AP. In AP-C rats, bombesin-stimulated pancreatic secretory function and HOMA-β-cell score were significantly lower than those in other groups of rats. In AP-R rats, protein per DNA ratio and pancreatic exocrine secretory function were significantly low compared with those in Control rats. In AP-S and AP-R/S rats, the above parameters recovered to the Control levels. Bombesinstimulated pancreatic exocrine response in AP-R/S rats was higher than in AP-S rats and almost returned to control levels. In the pancreas of AP-C rats, destruction of pancreatic acini, marked infiltration of inflammatory cells, and strong expression of α-smooth muscle actin, tumor necrosis factor-α and interleukin-1β were seen. Pancreatic rest reversed these histological alterations, but not atrophy of pancreatic acini and mild infiltration of inflammatory cells. In AP-S and AP-R/S

Obtaining a detailed understanding of the surface modification of supports is crucial;however,it is a challenging task for the development and large-scale fabrication of supported electrocatalysts that can be used as alternatives to Pt-based catalysts for the oxygen reduction reaction(ORR).In this study,commercial silicon carbide(SiC)was modified through surface oxidization(O-SiC)to support the use of Pd nanoparticles(Pd NPs)as electrocatalysts for *** obtained Pd/O-SiC catalysts exhibited better ORR activity,stronger durability,and higher resistance to methanol poisoning than that exhibited by commercial Pt/*** role of the support in enhancing the ORR performance,especially the oxidization of SiC surfaces,was discussed in detail based on the experimental characterizations and density functional theory *** underlying mechanism of the superior ORR performance of Pd/O-SiC catalysts was attributed to the charge transfer from SiC_(x)O_(y)to Pd NPs on the surfaces of SiC and the strong metal–support interactions(SMSIs)between Pd and SiC_(x)O_(y).The charge transfer enhanced the ORR activity by inducing electron-rich Pd,increased the adsorption of the key intermediate OOH,and decreased the Gibbs free energy of the critical ORR ***,SMSIs enhanced the ORR stability of the Pd/O-SiC *** study provided a facile route for designing and developing highly active Pd-based ORR electrocatalysts.

研究采用原则性多义词分析法对"water"与"水"的认知词义进行对比分析,发现二者的原型词义相同,水的动静、深浅、清浊、冷热和能量等特点在汉语和英语里都做了丰富的隐喻,而经隐喻拓展得来的延伸词义在两种语言里不尽相同。水这种物质所隐喻的概念既与人的身体经验相关,又受到哲学与宗教的影响。英语和汉语使用者对水这一概念的认知普遍性与差异性并存。因此,外语词汇教学应该注重词义的网络结构,统筹把握词语的原型词义与拓展词义。

为保证复杂化学相平衡问题准确求解,本文提出了一种基于Gibbs自由能最小原理的遗传与梯度混合算法(GAG)。为加快混合算法的计算速度和确保有效收敛,在计算过程中引入了变化参数,即算法中的遗传变异算子不再为常数而是根据平均适应度的大小进行动态调整。在进化的过程中,记录所有个体的近代适应度,适应度高的个体进入下一代。一旦发现满足设定条件的最优个体,本算法将沿着该个体的负梯度方向搜索快速逼近最优解。多个复杂气—固和气—液体系计算实例表明,该算法可以不断拓展求解空间,能以完全概率、高速并行搜索到全局最优解,并有效避免假收敛。该算法的最佳计算初始值区域为[-3,30],该混合算法即使初值点非常不好的情况下也可以确保收敛到最优值。为保证结果的准确性,所选计算实例的运行次数均不低于30次。
