The economics of conventional liner break-bulk cargo-handling efficiency

In this paper the authors, after examining the relationships between cargo handling performance of break-bulk cargo and ship and cargo related variables, demonstrate that systematic relationships exist in general cargo systems despite the many variables that affect handling operations.     

EXPRESSION AND SIGNIFICANCE OF MYOFIBROBLAST IN HEALING PROCESS OF BILE DUCT

One of the difficulties of biliary surgery lies inthe treatment of iatrogenic biliary stricture that isexpressed prominently after operation as scar con-tracture and anastomotic stenosis, especiaI1y theanastomotic stenosis at the porta hepatis and thearea above it. ln order to exp1ain the mechansim ofthe formation of iatrogenic biliary stricture, an ani-mal model of trauma--repair of bile duct was madein this experiment and the expression of myofi-broblast (MFB) during the whole process was ob…     

秦岭隧道排出水化学异常对地表水质影响评价

为评价隧道施工和排出水对地表水体水质的影响,对两条河流的水质进行了监测。现以饮用水水质都分因子为标准,将地表水水质划分为3个级别,并采用模糊综合评判法和灰色模型法对3个监测断面的地表水水质进行了综合评价,结果表明,两条河流水质良好,基本未受隧道施工及排出水的影响。

Investigating the link between cyclist volumes and air pollution along bicycle facilities in a dense urban core

In this paper we explore the air pollution levels along types of bicycle facilities using a NO₂ land use model previously developed for Montreal. We explore potential associations between bicycle volumes through signalized intersections and pollution levels at those intersections. We further investigate this relationship through the comparison of over thirty cycling corridors as well as an evaluation of the potential exposure of cyclists to air pollution along five routes. We observe NO₂ concentrations to be positively correlated with bicycle flows at the intersection level. We also observe that corridors with either a bicycle path or cycle track generally rank higher in terms of bicycle volume and also have higher NO₂ concentrations than corridors without bicycle facilities. This indicates that intersections and bicycle facilities with a large number of cyclists are also those characterized with the highest air pollution levels.     

重庆观音桥商圈单循环交通适应性分析

采用单向交通是解决城市交通拥挤最为常见的一种有效交通组织方式。重庆观音桥商圈单循环从运行初期到现在不断加剧的交通拥堵,一直支撑着商圈的经济社会发展。首先对单向交通的普适性、观音桥商圈单循环特殊性进行分析,然后从道路网密度、道路网结构、交通流组织3个方面论证分析观音桥商圈地区不适宜单向交通组织。     

中远川崎:中国造船高效劲旅

近些年,江苏省船舶工业发展势如破竹,成为全国乃至全世界令人瞩目的造船大省。国有企业、合资企业、民营企业在这黄金岸线旁百花齐放,共同奏响繁荣的乐章。其中南通中远川崎船舶工程有限公司(简称中远川崎)更是被业内人士誉为中国造船界的"传奇"。毋庸置疑,如此高的评价,并不仅仅是因为它不断书写着中国造船历史的纪录,更是因为它高效的造船模式成为江苏乃至全国造船效仿的模板。那么中远川崎是如何在中国造船界异军突起,又是凭借怎样的方式成为一支高效劲旅?带着疑问我们走近它。
