We report the preparation of poly(3,4-ethylene dioxythiophene)(PEDOT)-modified polyvinylidene fluoride electrospun fibers and their use as a novel adsorbent material for the removal of the anionic dye Methyl Orange(MO)from aqueous *** novel adsorbent material can be used to selectively remove MO on a wide p H range(3.0-10.0),with a maximum capacity of 143.8 mg/g at p H *** used in a recirculating filtration system,the maximum absorption capacity was reached in a shorter time(20 min)than that observed for batch mode experiments(360 min).Based on the analyses of the kinetics and adsorption isotherm data,one can conclude that the predominant mechanism of interaction between the membrane and the dissolved dye molecules is ***,considering the estimated values for the Gibbs energy,and entropy and enthalpy changes,it was established that the adsorption process is spontaneous and occurs in an endothermic *** good mechanical and environmental stability of these membranes allowed their use in at least 20 consecutive adsorption/desorption cycles,without significant loss of their *** suggest that the physical-chemical characteristics of PEDOT make these hybrid mats a promising adsorbent material for use in water remediation protocols and effluent treatment systems.

瑞吉欧学校(Reggio School)的设计理念是通过建筑环境来激发孩子们的探索和求知欲。因此,该建筑被视作一个复杂的生态系统,让孩子们在通过自我驱动的集体实验过程中引导自身教育,这也遵循了罗里斯·马拉古奇(Loris Malaguzzi)和意大利吉欧·艾米利亚市当地家长共同提出的教育理念,旨在增强孩子们应对不可预测挑战和潜在风险的能力。从该建筑的设计、建造到使用,都旨在超越可持续的范式,并将生态作为一种路径,继而将环境影响、多种群类别、物质动态化、集体治理以及教学方法通过建筑相交汇。

摘要：在生猪生产中常采用酸化日粮控制尿液pH作为缓解氮排放的手段,但长时间饲喂酸化日粮对骨骼矿化和矿物质平衡会有一定影响。研究旨在探讨长期在日粮中添加苯甲酸（BA）和氯化钙（CaCl2）对生长猪矿物质平衡和胃肠道微生物活性的影响。试验选用24头猪,采用单因素试验设计,分为4组,日粮包括BA 0或10 g·kg^-1和CaCl2 0或20 g·kg^-1的组合。在不添加CaCl2的日粮中,添加等摩尔钙水平的碳酸钙（CaCO3）。试验猪从36 kg饲喂到113 kg屠宰,并在其体增重为60-66kg,将其置于代谢笼,进行12 d代谢试验。
