1伊朗里海森林山坡上生长的欧洲鹅耳根系分布和抗张强度研究显示文摘对生长在伊朗北部丘陵地带的8株欧洲鹅耳的根面积比率和根系拉伸强度进行了测定,评估了欧洲鹅耳根系生物力学特性。应用剖面挖掘法测得土层深度为0.1米的样品根面积比率。共用了123份根样品分析根系拉伸强度。结果表明,根面积比率随土层深度增加而减小,变化规律遵从幂函数;上坡面和下坡面根面积比率无统计差别。根系可达到的最大土层深度为0.75米,但是最大根面积比率存在于土层深度0.1米内。下坡面最小和最大根面积比率分别为0.004%和6.431%;而上坡面的根面积比率分别为0.004%和3.995%。上、下坡面根数无显著差异,而且90%以上的根系深入到50-60厘米的土层中。Spearman双变量相关性分析结果表明,根面积比率与根数无显著关系。平均根拉伸强度为31.51±1.05MPa,且根系直径越粗根拉伸强度越小,遵从幂函数变化。图5表1参38。Ehsan Abdi Baris Majnounian Hassan Rahimi Mahmud Zobeiri 2009Journal of Forestry Research2009,20,2:4

3水泵水轮机在水轮机工况的动静干涉——导水通道的压力脉动显示文摘本文在比转速v=0.19水泵水轮机的缩小模型上进行了水轮机工况最大流量运行条件下的动静干涉研究。该工况的选择是为了得到最重要的动静干涉。在CFX5.7^TM中进行了从蜗壳到尾水管整个计算域的非定常流动的数值计算。计算域包含整个通道是为了减小计算误差,特别注意边界层的流动、周期性的分界面或者动静干涉分界面的栅距比例。同时也可以考虑蜗壳来流的不完全均匀流场。采用位于导水通道内的微型压阻式压力传感器进行压力测量。单个通道的压力脉动数字模拟与试验数据非常吻合。数字的结果分析展示了压力脉动在叶片通过频率(BPF)及其谐波处沿导水通道的变化。叶片通过频率处的最大压力幅值出现在动静干涉区域,但向着固定导叶方向其幅值迅速减小。但是,第一主频对应于两倍的叶片通过频率的压力幅值传到了蜗壳验证了由静止和转动部件的流场调制而出现了节径模数为-2的压力场。Alireza ZOBEIRI 2009国外大电机2009,,2:2

6Effects of grazing on natural regeneration of tree and herb species of Kheyroud forest in northern Iran显示文摘We investigated the effects of grazing on natural regeneration, quantity, and diversity of woody species and dominant herb species in Kheyroud forest in northern Iran. We sampled vegetation in 5m2 plots in custom units, which are demarcated resource areas traditionally used by local livestock producers. The authors quantified number of species, height of seedlings, and diameter of seedlings. Height classes were 0-30 cm, 30-130 cm, and >130 cm, and diameter classes were 0-2.5 cm, 2.5-5 cm and 5-7.5 cm. The density of seedlings declined with distance from corral until reaching the custom unit boundary. Most seedlings had diameters of 0-2.5 cm and heights of 0-30 cm. Predominant species, Carpinus betulus and Acer capadocicum, were in plots near the centers of custom units, Fagus orientalis, Acer velutinum, Quercus castanifolia species were dominant in plots near the custom unit boundary. Plant species such as Oplismenus undulatifolius, Euphorbia amygdaloides, Rubus fruticos and Pteridium aquilinum were dominant in plots nearer to forest corral. Healthy seedlings were more numerous in plots nearest the corral, while defective and deformed seedlings were more abundant away from the corral. We conclude that grazing had negative effects on the quantity and quality of vegetative regeneration. Continuation of overgrazing will not only endanger the sustainability of forest ecosystems, but also will increase the challenge of sustainable forest management.Mohsen Javanmiri Pour Mohmmad Reza Marvie Mohadjer Vahid Etemad Mahmoud Zobeiri 2012Journal of Forestry Research2012,23,2:1

16Efficacy and safety of Hemoheal cream in patients with hemorrhoids:a randomized double-blind placebo controlled clinical trial显示文摘OBJECTIVE:To evaluate the efficacy and safety of Hemoheal cream,an anti-hemorrhoid herbal preparation,(inspired by Persian medicine literatures in a double-blind,randomized placebo-controlled trial.METHODS:Hemoheal cream consists of aqueous extract of Allium ampeloprasum L.,Commiphora mukul(Hook.Ex Stocks)Engl and the oil of Sesamum indicum L.Fifty-two patients with symptomatic hemorrhoids were randomized to receive hemoheal cream or placebo for 3 weeks.The patients were evaluated before and after the intervention in terms of the severity of anal irritation,bleeding,anal itching,pain,defecation discomfort and swelling sense,and overall subjective improvement(%),as well as any reported adverse events.RESULTS:The results showed that after 3 weeks of treatment,distribution of anal irritation,bleeding,pain as well as swelling sense were significantly different(P<0.05),while the analysis showed no significant differences between two groups for anal itching and defecation discomfort(P>0.05).Furthermore,a significant difference was observed between the overall subjective improvement of Hemoheal cream and placebo groups(P=0.012).One patient in the treatment group complained of rashes on the application site.CONCLUSION:The present study showed a positive effect of Hemoheal cream in improving clinical signs and symptoms in patients with hemorrhoids.Mehdi Zobeiri Fatemeh Parvizi Roja Rahimi Fatemeh Heydarpour Hamid Reza Sheikhan Jafar Navabi Mohammad Hosein Farzaei 2021Journal of Traditional Chinese Medicine2021,41,2:0
17Robust and high-sensitivity thermal probing at the nanoscale based on resonance Raman ratio (R3)显示文摘Raman spectroscopy-based temperature sensing usually tracks the change of Raman wavenumber,linewidth and intensity,and has found very broad applications in characterizing the energy and charge transport in nanomaterials over the last decade.The temperature coefficients of these Raman properties are highly material-dependent,and are subjected to local optical scattering influence.As a result,Raman-based temperature sensing usually suffers quite large uncertainties and has low sensitivity.Here,a novel method based on dual resonance Raman phenomenon is developed to precisely measure the absolute temperature rise of nanomaterial(nm WS_(2) film in this work)from 170 to 470 K.A 532 nm laser(2.33 eV photon energy)is used to conduct the Raman experiment.Its photon energy is very close to the excitonic transition energy of WS_(2) at temperatures close to room temperature.A parameter,termed resonance Raman ratio(R3)Ω=I_(A1g)/IE_(2g) is introduced to combine the temperature effects on resonance Raman scattering for the A_(1g) and E_(2g) modes.Ω has a change of more than two orders of magnitude from 177 to 477 K,and such change is independent of film thickness and local optical scattering.It is shown that when Ω is varied by 1%,the temperature probing sensitivity is 0.42 K and 1.16 K at low and high temperatures,respectively.Based on Ω,the in-plane thermal conductivity(k)of a∼25 nm-thick suspended WS_(2) film is measured using our energy transport state-resolved Raman(ET-Raman).k is found decreasing from 50.0 to 20.0 Wm^(−1) K^(−1) when temperature increases from 170 to 470 K.This agrees with previous experimental and theoretical results and the measurement data using our FET-Raman.The R3 technique provides a very robust and high-sensitivity method for temperature probing of nanomaterials and will have broad applications in nanoscale thermal transport characterization,non-destructive evaluation,and manufacturing monitoring.Hamidreza Zobeiri Nicholas Hunter Shen Xu Yangsu Xie Xinwei Wang 2022International Journal of Extreme Manufacturing2022,4,3:0
