苏丹国水利大坝勘察——水上钻探施工流程

华北有色工程院苏丹公司(NCGEI)相继承揽了苏丹国北部、南部总计10个尼罗河水利大坝的勘察工作。在这些勘察工作中,尼罗河水上勘察的工作占主要部分,所以也就决定了水上勘察的重要性。水上勘察,施工难度大,水流湍急,定位难,钻进取芯难。为了解决这一难题,根据多年的施工经验和不懈的探索精神,创造了一套完整的水上钻探流程;包括如何根据钻探设备的重量来设计钻探平台,保证平台的稳定性,实用性,以及平台上的一些基础设施的安全使用;如何制造经济适用的锚,并根据孔位的位置抛锚定位等水上钻探应注意的事项等。

浅谈工程施工项目管理及其进一步规范和发展

工程施工项目管理是一项复杂的过程,施工企业施工管理以项目管理为重心,降低工程成本,提高经济效益和工程质量,保证工程进度,工程施工项目管理是建筑工程企业生存和发展的核心。工程项目的特点是由工程项目本身的单一性、资源的高投入行、建设周期的长久性、一次性生产长久使用性等特点决定。本文首先分析了建筑工程项目管理的特点,重点分析了工程施工项目管理及其进一步规范和发展的几点措施。     

浅谈工程施工索赔

施工索赔就是承包商由于非自身原因发生合同规定之外的额外工作或损失,所要求进行的费用和时间的补偿,索赔是一门“艺术”,它是一门融社会科学、自然科学为一体的边缘科学、涉及到工程技术、工程管理、贸易、法律、财会、公共关系等在内的众多专业学科知识。这里浅谈一下工程施工索赔。

The microbial domes of Wadi Muqshin pools,Sultanate of Oman

The paper reports studies on benthic microbial dome‐shaped mats found in hypersaline desert pools in Wadi Muqshin, southern Oman, and details the hydrogeological conditions of the pools, including water quality and recharge features. The upper 1 cm layers of these microbial mats are dominated by cyanobacteria, a phototrophic purple sulphur bacterium and diatoms. The dominant cyanobacterium is Microcoleus chthonoplastes and the purple layer below the upper layer is dominated by the photosynthetic sulphur bacterium Chromatium okenii. It is unusual to find standing water containing microbial domes in such a hyper‐arid, inland site which borders the Rub’ Al Khali (Empty Quarter). The flooding regime here depends largely on ‘fossil’ groundwater (Zone C, L.UER aquifer) mostly derived from the Pleistocene. Attempts to carry out desert agriculture with abstraction of this ‘fossil’ groundwater might cause the extinction of the Muqshin pools.     

钢结构建筑构造特征及表现实证浅析

经济与技术的发展使钢结构建筑迅速发展,尤其是国外技术和新产品的引进,钢结构品质的提高使钢结构建筑在我国得到了迅速发展.以下在分析钢结构建筑构造特征的基础上,对钢结构建筑的表现实证进行了初步探析.     

Estimation of solar radiation for Oman

Data of the time series of the daily solar irradiation on horizontal surfaces from 32 Spanish stations were analyzed. The method applied deals with stochastic components X(i,t) as following a first order Markov model. The results of the first order autocorrelation coefficient for each series vary from 0.23 to 0.49 in the Peninsula and from 0.33 to 0.62 in the Islands. The similitude, based on a contingency coefficient, between the frequency distributions of the simulated and experimental data of the residual time series X(i,t), is about 90% for every station.

A preliminary study on the status of invasive palm squirrels in Oman

ABSTRACT

Palm squirrels of the genus Funambulus are reported as invasive in the Sultanate of Oman for the first time. These squirrels have been recorded in seven locations in northern Oman contributing to a total of 11 records. Seven records were of the Five-striped northern palm squirrel, Funambulus pennantii (Wroughton, 1905) and species identification was indeterminate for four records. Funambulus pennantii was supposed to be the only species in United Arab Emirates (UAE), but here evidence is shown for the presence of the Three-striped Indian palm squirrel, Funambulus palmarum (Linnaeus, 1776) in Ras Al Khaimah. So, there is a possibility that this species may also occur in Oman. These palm squirrels are feeding on the fruits of Ziziphus spina-christi (L.) Desf. and the date palm, Phoenix dactylifera (L.) Mill. There is an indication that these species could become pests on date palms. Their abundance is low at present in Oman, but they are well established in the adjacent UAE from where sustained invasion is possible. They are also available through pet shops in Oman. The invasion of Oman by the palm squirrels is in its infancy and strategies should be formulated to eradicate/control them as a matter of priority.     

A short communication on growing Jatropha in Oman

A stripping technique has been used to cencentrate selected hydrocarbons present in water samples at the parts per billion level for analysis by gas chromatography. The chromatograms of hydrocarbons thus stripped from several different water samples show similarities. Washing out of atmospheric pollutants by rainfall is postulated as an explanation of these results. This hypothesis is supported by a comparison of the data with those for trace atmospheric analysis. The comparison shows that the same compounds are present in similar relative amounts both in water samples and the atmosphere. After a period of rain the atmospheric concentrations decrease whilst the water bound concentrations increase.
