Global software Development （GsD） is a well established field of software engineering with the benefits of a global environment. software Project Management （sPM） plays a key role in the success of GsD. As a result, the need has arisen to study and evaluate the downsides of sPM for GsD, to thereby pave the way for the development of new methods, techniques, and tools with which to tackle them. This paper aims to identify and classify research on sPM approaches for GsD that are available in the literature, to identify their current weaknesses and strengths, and to analyze their applications in industry. We performed a systematic Mapping study （sMs） based on six classification criteria. Eighty-four papers were selected and analyzed. The results indicate that interest in sPM for GsD has been increasing since 2006. As a class of approaches, the most frequently reported methods （40%） are those used for coordination, planning, and monitoring, along with estimation techniques that can be used to better match a distributed project. sPM for GsD requires further investigation by researchers and practitioners, particularly with respect to cost and time estimations. These findings will help overcome the challenges that must to be considered in future sPM research for GsD, especially regarding collaboration and time-zone differences.

Influence of Magnetic Treatment on salts Leaching： From soils of Different salinity Levels

Journal of Agricultural science and Technology(B) 2014年第6期4卷 434-439页

作者： Khalida Abdul-Karim Hassan Farhad Ali Hashim sarwar mohammed Rasheed Ahmed Department of soil and Water Faculty of Agriculture and Forestry Duhok University Duhok 42001 Kurdistan Region Iraq

Leaching behavior of individual ions from three saline soils (s1 = 85.0 ds/m, s2 = 53.92 ds/m and s3 = 38.14 ds/m) under magnetic water (MW) treatment or non-magnetized well water (WW) was investigated in column study. After five pore volumes, soil electrical conductivity (EC) decreased to a range between 2.99-3.29 ds/m under the two water treatments. The rate of soluble cations leached was Na + > Ca2+ > Mg 2+ > K + and Cl - > sO 4 2- > HCO 3 - for anions under the two water treatments. The greater amount of salt leached was during the first two pore volumes and was higher under MW treatment. Among soils, the higher the initial EC, the greater the amount of the salt leached. Measurements of the exchangeable Na + performed at the end of leaching experiment showed a high decrease in soil exchangeable Na + compared to the initial values of sodium adsorption ratio (sAR) and exchangeable sodium percentage (EsP) in the soil indicated that there was no prospects of soil sodification after leaching with five pore volumes.

Daily Carbon Monoxide （CO） Abundance from Airs over Peninsular Malaysia

引用

材料科学与工程（中英文版） 2010年第9期4卷 93-99页

作者： Jasim mohammed Rajab Hwee san Lim Mohad Zubir MatJafri Khiruldden Abdullah school of Physics Universiti Sains Malaysia Penang 11800 Malaysia

The objective of this study is to test the interpolation technique of Kriging interpolation for carbon dioxide (CO) mapping over peninsular Malaysia. We present the observations of atmospheric carbon monoxide (CO) by the atmospheric infrared sounder (Airs) onboard NAsA’s Aqua satellite. Comparisons of atmospheric carbon monoxide volume mixing ratio profiles (CO_VMR_eff_A) and CO total column amount (CO_total_column_A), Level-3 Daily (AirX3sTD) 1?×1? spatial resolution, as well as Effective CO Volume Mixing Ratio profile (CO_VMR_eff) (9 layers) ascending, Level-2 Daily (AirX2RET) standard are presented from Airs for two different periods, ascending (14/8/2005 & 13/8/2007) for both direct comparison and the comparison using the same a priori profile to study the abundance of carbon monoxide over peninsular Malaysia and the forest fires influences on its concentration. Observe a daily variation in CO emissions from the Indonesia forests fires with varying magnitudes in peak emission occurring in the regions that experienced extensive wildfires. The strong impact of forest fires makes it difficult to detect any evidence of the CO emission from industrial contributions on daily timescales. Examining satellite measurements, we find the enhanced CO emission correlates with large sources in Industrial and congested urban zones for normal circumstances, while the highest values of CO occurred when biomass burning during Indonesia forest fires on August 2005. Kriging interpolation technique produced the high accuracy based on the R and RMs value in this study. It is concluded that this technique accurately and precisely mapped CO concentration from Airs data over peninsular Malaysia, and the satellite measurements are able to measure the increase of troposphere CO concentrations over different regions.

背景灌注指数是一种无创性的来自干血氧饱和度监测的反映外周循环灌注的指标。本研究评估了灌注指数做为探索成人丙泊酚麻醉过程中血管内注入包含15μg肾上腺素的硬膜外试验剂量药物后变化指标的有效性；同时将它与常规评估标准-心率（HR）（如果升高≥10bpm则为阳性）及收缩压（sBP）（如果升高≥15mmHg则为阳性）进行了可靠性比较。方法40例全静脉麻醉、择期行普外科手术的患者随机静脉注射3ml含5μg/ml肾上腺素浓度为15mg／ml的利多卡因或3ml生理盐水（每组n=20）。监测注射后5分钟的心率、收缩压和灌注指数（PI）。结果注射试验剂量在39±15秒后平均最大灌注指数降低65％±13％。心率和血压的最大增量分别为49±25秒后19±8bpm和102±34秒后17±7mmHg。用灌注指数作为血管内注射的评估指标（如果灌注指数较注射前降低≥10％则为阳性），其敏感性、特异性、阳性预期值和阴性预期值是100％（95％可信区间CI=83％-100％）。相对地，心率和血压指标的敏感性分别为95％（CI=76％-99％）和90％（CI=70％-97％）。结论灌注指数是评价成年丙泊酚静脉麻醉患者血管内注射硬膜外试验剂量药物后常规血流动力学变化的可靠的选用指标。
