یکی از مهم‌ترین مدهای حمل‌ونقل عمومی شبکة مترو است که تأثیر بسزایی در کاهش ترافیک و آلودگی هوا دارد. ازدیگرسو، با توجه به هزینه‌های سرسام‌آور راه‌اندازی مترو، توسعة مرحله‌به‌مرحله بهره‌برداری یک خط اجرای خطوط دیگر به‌دست مدیران شهری مورد است. بنابراین، هدف این تحقیق بررسی میزان دسترسی متروی اصفهان افق 1410، رویکرد عدالت مکانی، دو جنبة افقی عمودی پنج طبقة اجتماعی، استفاده شاخص‌های ضریب جینی، منح...

In order to evaluate influential mechanisms for photosynthetic processes on the yields of an intercropping system composed maize (Zea mays), Lupinus sp. and Melilotus albus, three treatments were designed conducted in southern Moravia (Czech Republic) form agronomy trials. The included sole (SM), with (ML) field melilot (MM). Zea mays monitored using several chlorophyll fluorescence techniques ...

We provide here a general introduction on chlorophyll (Chl) fluorescence, then we present our measurements fast (< 1 s) induction curves (the so-called OJIP transients) dark-adapted intact leaves of Arabidopsis thaliana, under five different light intensities [in the range ~ 500 to 3,000 µmol(photons) m‒2 s‒1] using two instruments: Handy PEA (Hansatech Instruments, UK; e...

6alpha,7beta-Dihydroxyvouacapan-17beta-oic acid (1) was isolated from Pterodon polygalaeflorus Benth. Modification of 1 yielded 6alpha-hydroxyvouacapan-7beta,17beta-lactone (2) and then 6-oxovouacapan-7beta,17beta-lactone (3). Photosynthesis inhibition by 3 was evaluated in spinach chloroplasts. The uncoupled non-cyclic electron transport rate and ATP synthesis were inhibited by 3, which behave...

The changes of Chl a fluorescence induction curve in response to different salinity levels in Canola (Barassica napus, L.) plants were investigated. The canola seedlings were exposed to salt stress (100 mM and 200 mM NaCl) for 7 days and Chl a fluorescence induction kinetics was analysed. By using the OJIP-test, various parameters like VJ, area, N, φPo, φEo, ψo, RC/ABS and PIABS were calculated...

Biochemical and functional changes in photosystem II (PSII) were investigated during natural senescence of maple (Acer platanoides L.) leaves. Three different types of senescing leaves were used: early senescent green (G), yellow green (YG) and yellow (Y). The main goal of this study was to investigate the dynamics of degradation of major photosynthetic proteins (D1, LHCII and Rubisco LSU) and ...

The changes in PSII photochemistry in Spirulina platensis cells exposed to salinity stress (0-0.8 M NaCl) for 12 h were studied. Salinity stress induced a decrease in oxygen evolution activity, which correlated with the decrease in the quantum yield of PSII electron transport (PhiPSII). Phycocyanin content decreased significantly while chlorophyll content remained unchanged in salt-stressed cel...

To investigate the effects of high-temperature stress on chlorophyll fluorescence induction kinetics peony and to determine indicators for rapid screening varieties responding high temperatures, three four-year-old variety, ‘Fengdanbai’, ‘Huhong’, ‘Yinhongqiaodui’, were selected as materials. The photosynthetic curves (Pn-PAR) fast (OJIP curves) leaves measured at different times under conditio...
