Diversity and biomass of different functional groups of herbaceous species along an altitudinal gradient in the semi-arid Zagros mountain forests of Iran

The response of diversity and biomass of herbaceous functional groups along an altitudinal gradient in mountainous forests of southern Zagros,Khuzestan Province,Iran was studied by sampling vegetation in 30 circular 1000-m^2 plots in herb layer of the forest floor within 646–2447 m asl(lowland:2000 m asl).The most important herbaceous functional groups were classified based on two aspects of growth form:annuals–perennials,grasses–*** the relationship between the diversity,richness,evenness,biomass and elevation was *** results showed that the annual functional group in the low-and midland classes,and perennial functional group in the lowland class had the highest species diversity and evenness in annual and perennial functional groups,respectively(p<0.01).The perennials in the highland class had the maximum total,above-and belowground dry biomass(p<0.01).On the other hand,the forb functional group in the lowland class had the greatest species diversity,richness,and evenness(p<0.01)and in the highland class had the maximum total dry,above-and belowground dry biomass in the grass and forb functional groups(p<0.01).Increasing the diversity,richness,and species evenness resulted in a decrease in the plant dry biomass.

Effect of intervention and type of forest management on quality andquantity characteristics of dead wood in managed and reserve forests: Acase study

引用

Journal of Forestry Research 2012年第3期23卷 413-418页

作者： Kambiz T. Abkenari Fateme Akbari Babak pilehvar Faculty of Natural Resources University of GuilanRashtP. O. BOX:41996-13769Iran Faculty of Agriculture Lorestan UniversityKhoramabadLorestanIran

We compared the dead wood （DW） conditions of Chesh- meh-sar forest and Sardab forest with different management history, including reserve forest and harvested forest. The First forest took 100% inventory from all the available DW. Also dead trees were compared in terms of species, shape, location and quality of fracture in both forests. Volumes of dead wood in Cheshmeh-sar and Sardab forests were 207.47 and 142.74 m3, respectively. Due to this significant difference, impact on the management level was determined. In Cheshmeh-sar forest, 42% of dead trees were standing and 58% were fallen type while in Sardab forest 38.6% were standing and 61.4% fallen. But the difference was not statis- tically significant l^etween them （p = 0.0587）. In terms of quality, dead trees of hard, soft and hollow had the highest frequency, respectively. However, 71.5% of DW was seen as hard dead in Cheshmeh-sar forest while hard dead trees in Sardab forests were 54.2%. Soft quality degree of dead trees which formed in Cheshmeh-sar and Sardab forest were calcu- lated as 26.6% and 43.4% respectively. Also 30% of the dead trees of Sardab forest were eradicated while in Cheshmeh-sar this amount was reduced to 12%. Due to this significant difference （（P=0/018）, it is concluded that the type of management and human interference are affecting the quality of dead trees and makes us to think the human in- terferences could effect on the ecosystem of touched forests.

Effect of Low-Pressure Nitrogen DC Plasma Treatment on the Surface Properties of Biaxially Oriented Polypropylene, Poly (Methyl Methacrylate) and Polyvinyl Chloride Films

引用

Plasma Science and Technology 2013年第4期15卷 362-367页

作者： S. Hamideh MORTAZAVI Mahmood GHORANNEVISS Soheil pilehvar Sina ESMAEILI Shamim ZARGHAM S. Ebrahim HASHEMI Hamzeh JODAT Plasma Physics Research Center Science and Research Branch Islamic Azad University Tehran Iran Polymer Engineering Group Composite Science and Technology Research CenterTehran Iran Plasma Physics Research Center Science and Research Branch Islamic Azad UniversityTehran Iran Polymer Engineering Center Science and Research Branch Islamic Azad UniversityTehran Iran Polymer Engineering Group Composite Science and Technology Research CenterTehran Iran

In this study, commercial biaxially oriented polypropylene （BOPP）, polyvinyl chlo- ride （PVC） and poly （methyl methacrylate）（PMMA） films were treated with nitrogen plasma over different exposure times in a Pyrex tube surrounded by a DC variable magnetic field. The chemi- cal changes that appeared on the surface of the samples were investigated using Fourier transform infrared （FT4R） spectroscopy and attenuated total reflectance Fourier transform infrared （ATR- FTIR） spectroscopy after treatment for 2 min, 4 min and 6 rain in a nitrogen plasma chamber. Effects of the plasma treatment on the surface topographies and contact angles of the untreated and plasma treated films were also analyzed by atomic force microscopy （AFM） and a contact angle measuring system. The results show that the plasma treated films become more hydrophilic with an enhanced wettability due to the formation of some new polar groups on the surface of the treated films. Moreover, at higher exposure times, the total surface energy in all treated films increased while a reduction in contact angle occurred. The behavior of surface roughness in each sample was completely different at higher exposure times.

Simulation and Design of a Low Crosstalk Hexagonal Photonic Crystal Crossover Waveguide

引用

Optics and Photonics Journal 2013年第2期3卷 209-211页

作者： Elnaz pilehvar Hassan Kaatuzian Mohammad Danaie Faculty of Elecrical Engineering Semnan University Semnan Photonics Research Lab.(P.R.L.) Dept. of Electrical Engineering Amirkabir University of Tech. Hafez Ave. Tehran Iran

In this paper, an optical waveguide junction is introduced to reduce crosstalk based on a hexagonal structure of photonic crystals for TE modes. The wavelength is 1330 nm which is an important wavelength for optical fiber data transmission. Simulation results show that the proposed design exhibits a reduction of -50 dB in crosstalk. It translates to a considerable isolation improvement between two crossover waveguides. FDTD method is used to obtain the transmission coefficient.
