Species of Paulownia are fast-growing trees that are planted in many countries in green spaces and agroforestry systems. We studied the influence of irrigation on the diameter growth of 2-year-old Paulownia tomentosa saplings planted in 3 m 9 3 m grids at Nazlou Campus of Urmia University, Iran. Completely randomized experimental design was used with four irrigation amount, viz.10, 15, 20 and 25 L, and three irrigation intervals, viz. 3-and 6-days, in 8 replications. During the growth season, we measured collar diameters of all saplings at the end of each month. Diameter growth declined with reduced irrigation amount and increased irrigation interval. The lowest average diameter growth（9 mm） was recorded for 10 L water at 6-day intervals and maximum average diameter growth（28.7 mm） was recorded for 25 L volume at 3-day intervals. The latter treatment resulted in significantly greater diameter growth than any other treatment（except20 L at 3-day intervals）. More than 80 % of diameter growth was achieved in the first 3 months. Therefore, it is essential to irrigate with 25 L of water at 3-day intervals during the first three growth months to achieve maximum diameter growth for 2-year-old P. tomentosa saplings.

温带和热带森林中的森林边缘现象已经得到了很好的研究,但在稀疏的橡木林片段中的相关研究却较为缺乏。本文研究了稀疏橡木林片段对植物物种多样性和土壤特性的边缘影响。本研究沿着伊朗克尔曼沙赫省3个小型(10 ha)橡木林片段的3个横断面收集了从边缘到内部的相关数据,测量了0(森林边缘)、25、50、100和150 m处的草本植物(高度<0.5 m)和土壤特性。使用香农指数量化了物种多样性,使用稀疏标准化方法比较了两个大小不同片段中的物种丰富度,并应用了非度量多维测度排序研究了物种组成的变化。通过随机化测试估算了边缘影响的距离,并利用Tukey HSD事后检验法的广义线性混合模型评估了距边缘距离和片段大小对多样性和土壤特性的影响。研究结果表明,大小片段边缘具有较高的物种丰富度、多样性和均匀度,而大片段边缘的土壤氮和有机碳含量则较内部更低(边缘50 m范围内的变化最大)。大小片段的物种组成、土壤有机碳和氮总量都存在显著差异。本研究关于这些稀疏森林对草本植物和土壤特性产生显著边缘影响的发现,对于边缘研究,尤其是边缘和草本植物的相关研究具有重大贡献。

Objective:To explore potential natural products against severe acute respiratory syndrome coronavirus(SARS-CoV-2)via the study of structural and non-structural proteins of human coronaviruses.Methods:In this study,we performed an in-silico survey of 25 potential natural compounds acting against SARS-CoV-2.Molecular docking studies were carried out using compounds against 3-chymotrypsin-like protease(3 CL^(PHO)),papain-like protease(PL^(PRO)),RNA-dependent RNA polymerase(RdRp),non-structural protein(nsp),human angiotensin converting enzyme 2 receptor(hACE2 R),sapike glycoprotein(S protein),abelson murine leukemia viral oncogene homolog 1(ABL1),calcineurin-nuclear factor of activated T-cells(NFAT)and transmembrane protease serine 2.Results:Among the screened compounds,amentoflavone showed the best binding affinity with the 3 CL^(PRO),RdRp,nsp13,nsp15,hACE2 R,ABL1 and calcineurin-NFAT;berbamine with hACE2 R and ABL1;cepharanthine with nsp10,nsp14,nsp16,S protein and ABL1;glucogallin with nsp15;and papyriflavonol A with PL^(PRO)protein.Other good interacting compounds were juglanin,betulinic acid,betulonic acid,broussooflavan A,tomentin A,B and E,7-methoxycryptopleurine,aloe emodin,quercetin,tanshinone I,tylophorine and furruginol,which also showed excellent binding affinity towards a number of target proteins.Most of these compounds showed better binding affinities towards the target proteins than the standard drugs used in this study.Conclusion:Natural products or their derivatives may be one of the potential targets to fight against SARS-CoV-2.

A reappraisal of active faults in central-east Iran(Kerman province)

Fault lineaments are the main input data in earthquake engineering and seismology studies.This study presents a digitally-based active fault map of the Kerman region in central-east Iran which experienced several devastating earthquakes on poorly exposed and/or not identified active faults.Using Landsat 8 data,we have carried out the image-based procedures of fault mapping,which include applying the contrast stretching technique,the principal component analysis,the color composite technique,the spectral rationing,and creating the false-color composite images.Besides,we have cross-checked the resulting map with the geological maps provided by the Geological Survey of Iran to decrease the associated uncertainties.The resulting map includes 123 fault segments,still,a part of which has been expressed in the previously compiled active-fault maps of Iran.Indeed,the new one is mapping the poorly exposed active faults,so-called secondary faults,which are able to produce strong events.These faults are primarily associated with poorly defined areas that accommodate low levels of seismicity;however,sporadic strong events are likely to occur.It has also been investigated that these kinds of faults are seismogenic and are able to produce destructive events.In total,the outcome of this study can also be jointed with seismic studies for investigating parts of the earthquake activity in central-east Iran,in particular for the fault-based approaches in impending earthquake-resistant buildings.
