Colimitation and the coupling of N and P uptake kinetics in oligotrophic mountain streams
Ecosystem element cycles can be tightly linked by both abiotic and biotic processes. Evidence for multi-element limitation (i.e., colimitation) of a variety of ecosystem processes is growing rapidly, yet our ability to quantify patterns of coupled nutrient dynamics at the ecosystem level has been hindered by logistical and methodological constraints. Here we quantify coupled nitrogen and phosph...
متن کاملREACTIVITY OF N-SUBSTITUTED p-BENZO AND p-NAPHTHOQUINONEIMINE N-OXIDES TOWARD DIPOLAROPHILES
The dipolar cycloaddition reactivity of N-(1-naphthy1)-1,4- benzoquinoneimine N-oxide and N-phenyl-1,4- naphthoquinoneimine Noxide are investigated, The latter gives the expected adducts with common dipolarophiles such as acrylonitryle, methyl methacrylate, dimethylacetylene dicarboxylate and N-phenylmaleimide. The reactivity of the former nitrone is found to be minimal. It undergoes, how...

متن کاملsupply and demand security of energy in central asia and the caucasus
امنیت انرژی به معنی عرضه مداوم و پایدار همراه با قیمت های معقول در حامل های انرژی، که تهدیدات امنیتی، سیاسی، اقتصادی، محیط زیستی و روانی را کاهش دهد. امروزه نفت و گاز تنها، کالای تجاری نیست بلکه بعنوان ابزار سیاسی مورد استفاده قرار می گیرد.اختلاف میان روسیه و اکراین بر سر انرژی در ژانویه 2006، تهدیدی برای امنیت انرژی اروپا ایجاد کرد. در این تحقیق ما تلاش کردیم که نقش انرژی آسیای میانه و قفقاز ر...
