| 1 | 采用锰矿从水溶液中吸附铅和镉离子(英文)显示文摘采用低成本的本地可得的天然锰矿作为吸附剂,研究吸附工艺从水溶液中脱除铅离子和镉离子。利用伪一级、伪二级动力学和颗粒内扩散模型检验动力学吸附数据,计算和比较这些动力学模型的吸附速率常数,发现用伪二级动力学模型能最佳地描述吸附动力学。将 Langmuir 和 Freundlich 等温吸附模型用来拟合不同温度下的平衡数据,发现实验数据与 Langmuir 模型拟合得更好。采用 Langmuir 等温吸附模型计算出锰矿吸附铅离子和镉离子的最大容量分别为 98 和 6.8 mg/g。计算了热力学参数,如吸附吉布斯自由能的变化、焓变与熵变。结果表明,锰矿作为吸附剂对铅和镉的吸附反应是自发的吸热反应。因此,锰矿作为一种天然的矿物吸附剂,可以替代现有的吸附剂来脱除水溶液中的铅离子和镉离子。 | Aylin SNMEZAY M.SALIM NCEL Nihal BEKTAS | 2012 | Transactions of Nonferrous Metals Society of China2012,22,12: | 6 |

| 3 | 早期床旁运动干预在心脏手术后患者心脏康复中的应用效果显示文摘目的评估早期床旁运动干预对心脏瓣膜手术后患者康复的影响。方法纳入40例心脏瓣膜疾病患者,其中20例患者[(49.05±3.728)岁]术后第3、4、5天接受床旁运动干预(3 min/d,干预组),其余20例患者[(47.95±3.214)岁]未接受床旁运动干预(对照组)。术前进行心理教育,并通过标准化问卷简表对患者单独评估。通过指脉氧仪及6 min步行距离来评估心脏康复效果。结果干预组心脏瓣膜患者术后3 d的SpO_(2)水平高于对照组(P<0.05)。干预组术后5 d心率降至基线水平,低于对照组(P<0.05)。结论初级床旁运动(3 min/d)可以提高SpO_(2)、降低心率,进而改善患者基线状态,促进患者康复。 | M.Rafi HAMIDI 陈轶洪 弥守玲 陆云涛 丛硕 王文硕 Hosna HAMIDI 杨晔 M.Salim BAHRAMAND Ali Ateel DAIFOLADI Babrak SAYEDZADA 刘欢 魏来 王春生 | 2022 | 中国临床医学2022,29,4: | 1 |
| 4 | Hybrid Sensor Selection Technique for Lifetime Extension of Wireless Sensor Networks显示文摘Energy conservation is a crucial issue to extend the lifetime of wireless sensor networks(WSNs)where the battery capacity and energy sources are very restricted.Intelligent energy-saving techniques can help designers overcome this issue by reducing the number of selected sensors that report environmental measurements by eliminating all replicated and unrelated features.This paper suggests a Hybrid Sensor Selection(HSS)technique that combines filter-wrappermethod to acquire a rich-informational subset of sensors in a reasonable time.HSS aims to increase the lifetime of WSNs by using the optimal number of sensors.At the same time,HSS maintains the desired level of accuracy and manages sensor failures with the most suitable number of sensors without compromising the accuracy.The evaluation of the HSS technique has adopted four experiments by using four different datasets.These experiments show that HSS can extend the WSNs lifetime and increase the accuracy using a sufficient number of sensors without affecting theWSNfunctionality.Furthermore,to ensure HSS credibility and reliability,the proposed HSS technique has been compared to other corresponding methodologies and shows its superiority in energy conservation at premium accuracy measures. | Khaled M.Fouad Basma M.Hassan Omar M.Salim | 2022 | Computers, Materials & Continua2022,,3: | 0 |
| 5 | Role of Ca^(2+) on Growth of Brassica campestris L.and B.juncea(L.) Czern & Coss under Na^+ Stress显示文摘Root and shoot growth of Brassica campestris L.and B.juncea increased significantly(P<0.01) with enhanced Ca2+ treatment along with 60 mM NaCl in the root medium.The maximum fresh mass of shoot and root in B.juncea was recorded at 10 mM Ca2+ concentration.The relative growth rate of shoot of both species reached its maximum at 8 mM of Ca2+ concentration.Average rate of Ca2+ intake(Ca) was higher in B.juncea than B.campestris.In B.juncea,the average transport of Ca2+ to shoot increased by 19%,38%,119%,125% and 169% compared with the control.Furthermore specific utilization rate of Ca2+ was higher in B.juncea than B.campestris.In B.campestris it increased by 9%,32%,41% and 59% at 4,6,8,and 10 mM of calcium in comparison to 2 mM Ca2+ treatment.At 4,6,8 and 10 mM of Ca2+ application,the increase in the leaf area ratio was 10,17,23 and 30%,respectively.In the shoot and root portions of B.campestris and B.juncea,Ca2+ had a linear relationship with potassium and sulfur,whereas it was in antagonism with sodium ion. | Badr-uz-Zaman M.Salim Rehana Asghar | 2010 | Journal of Integrative Plant Biology2010,52,6: | 0 |
