Berth and loading and unloading machinery are not only the mainfactors that affecting the terminal operation, but also the main starting point ofenergy saving and emission reduction. In this paper, a genetic Algorithm Framework is designed for the berth allocation with low carbon and high efficiency atbulk terminal. In solving the problem, the scheduler’s experience is transformedinto a regular way to obtain the initial solution. The individual is represented as achromosome, and the sub-chromosomes are encoded as integers, the roulettewheel method is used for selection, the two-point crossing method is used forcross, and the exchange variation method is used for variation in the procedureof designing the Algorithm. Considering the complexity of berth schedulingproblem and the diversity of constraints and boundary conditions, the geneticalgorithm combines with system simulation to get the final scheme of berthallocation. This model and algorithm are verified to be practical by analyzingmultiple sets of examples of shorelines with different lengths. When comparedwith the traditional algorithms in three aspects which includes berth offsetdistance, departure delay cost and energy consumption of portal crane, the resultindicates that the improved algorithm is more effective and feasible. The studywill help to lower energy consumption and resource waste, reduce environmentalpollution, and provide a reference for low-carbon, green and sustainable development of the terminal.

A reliable and rapid laboratory procedure was developed for rapid screening of reverse osmosis(RO) membrane anti-scalants and compared with existing laboratory methods. This laboratory procedure consists of two parts according to the characteristics of screening RO membrane anti-scalants: preliminary screening of anti-scalants by static method and further by dynamic methods based on the result of static method. Conductivity method, critical pH method and turbidity method were selected as the methods for preliminary screening of RO anti-scalants, and drainage gradient method and dose gradient method were chosen as the dynamic methods for further screening RO anti-scalants.

利奥波德·布卢姆是爱尔兰作家詹姆斯·乔伊斯的长篇小说《尤利西斯》中的主要人物,无论是受到爱尔兰社会的冷漠、歧视,还是遭遇妻子的背叛,他都能常怀善心、极度忍耐。他的善与忍源于他对“爱邻如己”犹太道德诫律的恪守。他的善与忍还反映在他的婚姻关系中,布卢姆原谅妻子莫莉的不忠,把她看作自己的“骨中骨、肉中肉”,看作自己生命中不可或缺的一部分,这是他对人类始祖亚当对妻子夏娃立下的婚姻誓约的遵守。面对妻子的婚外情,布卢姆没有责罚她,而是极度包容并坚守婚姻,这是他对犹太婚姻契约的信守。概而言之,恪守“爱邻如己”的犹太道德诫律、遵守人类始祖的婚姻誓约、信守犹太婚姻契约,是布卢姆善与忍的伦理原因。
