1Modeling and Analysis of Mechanization Projects of Wheat Production by GERT Networks显示文摘In crop production systems,all operations such as seed bed preparation,etc.,must be accomplished on time,if yield reduction and low quality product are to be avoided.Therefore all operations in mechanized cropping projects require precise scheduling,planning and management.The basic approach in all scheduling techniques is to form a network of activities and events relationships that graphically portrays the sequential relations between the tasks in a project.Such a network would as a powerful tool available a farm manager to plan,schedule,monitor and control a project.Since GERT(Graphical Evaluation and Review Technique) networks have most of advantages associated with networks and available system analyst in exact evaluation of certain types of networks,in this research it was used and mechanized wheat production system was simulated,modeled and analyzed.Critical activities,events and path were determined.Results showed that the network model was able to answer any statistic questions concerning with the project.Network models,particularly GERT networks are increasingly powerful tool for modeling,scheduling,planning,controlling,and analyzing of agricultural mechanization projects.Reza Abdi Hamid Reza Ghasemzadeh Shamsollah Abdollahpour Majid Sabzeparvar Adel Dabbag Mohamadi Nasab 2010Agricultural Sciences in China2010,9,7:14
2Performance evaluation of a modified step-feed anaerobic/anoxic/oxic process for organic and nutrient removal显示文摘A pilot scale modified step-feed process was improved to increase nutrient(N and P)and organic removal operations from municipal wastewater.It combined the step-feed process and a method named 'University of Cape Town(UCT)'.The effect of nutrient ratios and inflow distribution ratios were studied.The highest uptake efficiency of 95% for chemical oxygen demand(COD)has been achieved at the inflow distribution ratio of 40/35/25.However,maximum removal efficiency obtained for total nitrogen(TN)and phosphorus at 93% and 78%,respectively.The average mixed liquor suspended solids(MLSS)was 5500 mg·L^(-1).In addition,convenient values for dissolved oxygen(DO)concentration,and p H were obtained throughout different stages.The proposed system was identified to be an appropriate enhanced biological nutrient removal process for wastewater treatment plants owing to relatively high nutrient removal,sturdy sludge settle ability and COD removal.A.R.Majdi Nasab S.M.Soleymani M.Nosrati S.M.Mousavi 2016Chinese Journal of Chemical Engineering2016,24,3:6
3基于瞬时产量递减分析确定天然裂缝性油藏平均地层压力显示文摘以Warren和Root等提出的裂缝-孔隙双重介质模型为基础,拓展延伸了Mavor、Cinco-Ley和Daprat等的裂缝系统拟稳态-定产量生产的解及基质系统拟稳态-定压力生产的解,提出了根据天然裂缝性油藏定压开采的瞬时产量递减准确估算油藏平均压力的新方法。具体方法为:分别将基质产量方程和裂缝产量方程两端取自然对数,得到两条直线;再利用其斜率和截距确定弹性储容比、油藏总储容以及泄油面积,最后确定平均地层压力。经算例和实例验证,新方法简单实用,与物质平衡法和Tiab直接合成技术法得到的估算结果十分接近。Daryasafar Amin Amareh Iman Fathi Nasab Mohammad Kharrat Riyaz Jalilian Milad 2015石油勘探与开发2015,42,2:5
4用离子交换法从潜在钪资源的铜浸出残液中回收钪显示文摘伊朗Sarcheshmeh铜联合企业的铜浸出残液含有高达3 mg/L的钪,明显高于许多现有的钪资源,因而成为用离子交换法回收钪的可能原料。使用Visual Minteq软件确定在矿山工艺条件下可能形成的离子物种,从而选择合适的离子交换树脂。所选择的阳离子树脂在静态试验中用于含有离子的合成溶液,以及在静态/动态试验中用于实际的铜矿浸出残液。室温和pH值为1.5时,钪的吸附率最高。在动态试验中,残液流量为450 BV时,树脂达到完全饱和。在恒定时间的静态洗脱试验中,使用碳酸钠洗脱,树脂中Sc、Y、Ce的解吸率高于Fe、Al和Cu。动态洗脱试验结果表明,洗脱的优先顺序和洗脱程度具有相似的趋势。动态试验样品的解吸结果表明,浓缩比达到60:1,可得到186 mg/L的富钪溶液。H.HAJMOHAMMADI A.H.JAFARI M.ESKANDARI NASAB 2020Transactions of Nonferrous Metals Society of China2020,30,11:2

17A QUICK AND GREEN IONIC LIQUID-MEDIATED APPROACH FOR THE SYNTHESIS OF HIGH-PERFORMANCE, ORGANOSOLUBLE AND THERMALLY STABLE POLYIMIDES显示文摘Three diamine monomers with different derivatives of imidazole heterocyclic ring and meta-linked aryl ethers were synthesized and used in polycodensation reaction with various commercial dianhydrides for preparation of a series of novel poly(ether-imide) (PEI)s. The polycodensation reactions were carried out by using conventional method and in a green medium of ionic liquid (IL) without using NMP-pyridine-acetic anhydride. The PEIs were obtained in good yields (80% 96%) with moderate viscosity (0.48 0.66 dL/g) in a shorter reaction time (10 h) in IL as compared with the conventional method (36 h). All of the polymers were amorphous in nature, showed excellent solubility in amide-type polar aprotic solvents with ability to form tough and flexible films, and excellent thermal stability with Tgs in the range of 212 340 ℃ and 10% weight loss temperature (T10) up to 570℃ in N 2 and 528 ℃ in air.Mehdi Taghavi Mousa Ghaemy Marjan Hassanzadeh Seyed Mojtaba Amini Nasab 2013Chinese Journal of Polymer Science2013,31,4:1
