Collaborative Project Management: A Systemic Approach to Heavy Equipment Manufacturing Project Management

Quite often over the last decade, heavy equipment manufacturers are trying to improve their project management performance with the use of effective project management methods. However, the challenges encountered aren’t isolated problems and a systemic approach is required. This paper exemplifies how a systemic approach can be applied to heavy equipment manufacturing project (HEMP) management, through of a multifaceted vision. The findings present in the paper are based on a two-year case study in a metallurgic equipment manufacturing enterprise in China. Based on the analysis of HEMP management problems and the contributions on systemic approach application in project management, the paper enriches existing theory by: (1) interpreting the HEMP management system with the top-down disassembly method; (2) developing the collaborative project management approach with a systems view highlighting the project characteristics management and inter-departmental collaboration; (3) making suggestions for systemic approach application in project management. For practitioners and researchers, the findings are particularly meaningful for manufacturing project management and systemic approach application.     

卫生部药品标准中药成方制剂中含反药药对成方制剂收载情况与分析

"十八反"、"十九畏"作为中医药领域传统的配伍禁忌,一直沿用至今,但由于临床不乏反药同用治疗某些疾病突显奇效的病案,其是否确属绝对配伍禁忌,是众多学者及临床医生关注的热点问题.<中华人民共和国卫生部药品标准·中药成方制剂>是卫生部为解决中药材品种混乱问题,保证人民用药安全有效,颁布的具有权威性的法定标准.据统计,其1～20册共收载成方制剂4052个品种,其中含反药配伍的成方制剂65个,包括含"十八反"药对的品种43个,含"十九畏"药对的品种25个,既含"十八反"又含"十九畏"药对的品种3个.经分析可知,该标准含反药药对的成方中以乌头类与半夏、官桂与赤石脂配伍使用为多;其临床应用特点,含"十八反"药对的成方主要用于风湿痹病、跌打损伤,剂型以丸剂、膏药、橡胶膏剂为主,口服与外用比例相当;含"十九畏"药对的成方主要用于月经不调,以丸剂口服为主.在处方药味数方面,含反药药对的成方以16～30味的处方较多.

甘南州草地生态系统现状及可持续发展对策

甘南藏族自治州是甘肃省重点牧区,也是黄河、长江两大水系源区。天然草地面积272.3万hm2,但是,不合理地开发和利用,导致草地生态系统日趋恶化,生产能力下降,严重制约地区经济发展和农牧民脱贫致富。研究如何完善生产经营状况,维持草地生态系统是甘南牧区面临的主要问题。以草定畜,综合治理,科学合理利用是改善草地生态系统和畜牧业可持续发展的唯一途径。

SLC2A9 is a newly identified urate transporter influencing serum urate concentration, urate excretion and gout

Uric acid is the end product of purine metabolism in humans and great apes, which have lost hepatic uricase activity, leading to uniquely high serum uric acid concentrations (200-500 microM) compared with other mammals (3-120 microM). About 70% of daily urate disposal occurs via the kidneys, and in 5-25% of the human population, impaired renal excretion leads to hyperuricemia. About 10% of people with hyperuricemia develop gout, an inflammatory arthritis that results from deposition of monosodium urate crystals in the joint. We have identified genetic variants within a transporter gene, SLC2A9, that explain 1.7-5.3% of the variance in serum uric acid concentrations, following a genome-wide association scan in a Croatian population sample. SLC2A9 variants were also associated with low fractional excretion of uric acid and/or gout in UK, Croatian and German population samples. SLC2A9 is a known fructose transporter, and we now show that it has strong uric acid transport activity in Xenopus laevis oocytes.     

Switch from protective to adverse inflammation during influenza: viral determinants and hemostasis are caught as culprits

Influenza viruses cause acute respiratory infections, which are highly contagious and occur as seasonal epidemic and sporadic pandemic outbreaks. Innate immune response is activated shortly after infection with influenza A viruses (IAV), affording effective protection of the host. However, this response should be tightly regulated, as insufficient inflammation may result in virus escape from immunosurveillance. In contrast, excessive inflammation may result in bystander lung tissue damage, loss of respiratory capacity, and deterioration of the clinical outcome of IAV infections. In this review, we give a comprehensive overview of the innate immune response to IAV infection and summarize the most important findings on how the host can inappropriately respond to influenza.     

不同船速比对改向避让效果的影响

为了研究船速比在船舶驾驶员制定改向避让决策时的影响,运用船舶相对运动几何原理建立船速比与改向避让施舵点、改向幅度之间的数学模型,分析不同目标交汇特征下船速比(K≥1)分别对施舵点和改向幅度的影响.仿真实验结果表明,船速比(K≥1.5)较大的情况下,本船按《国际海上避碰规则》(以下简称规则)改向避让的效果不显著,对左正横...
