Changes in foliar nutrient content and resorption in Fraxinus excelsior L., Ulmus minor Mill. and Clematis vitalba L. after prevention of floods
This paper focuses on the impact of flood on tree mineral nutrition through measurement of resorption (i.e. transfer of nutrients from leaves to perennial organs). Nutrient (N, P, K, Mg, Ca) concentrations in leaves of three representative species, Fraxinus excelsior L., Ulmus minor Mill. and Clematis vitalba L. were measured before and after abscission on flooded and unflooded hardwood forests...
متن کاملIdentification of Xylem Occlusions Occurring in Cut Clematis (Clematis L., fam. Ranunculaceae Juss.) Stems during Their Vase Life
During the vase life of cut stems obstruction of xylem vessels occurs due to microbial growth, formation of tyloses, deposition of materials in the lumen of xylem vessels and the presence of air emboli in the vascular system. Such obstructions may restrict water uptake and its transport towards upwards thus lowering their ornamental value and longevity of cut flowers. Clematis is a very attract...
متن کاملExtraction of Russian Sentiment Lexicon for Product Meta-Domain
In this paper we consider a new approach for domain-specific sentiment lexicon extraction in Russian. We propose a set of statistical features and algorithm combination that can discriminate sentiment words in a specific domain. The extraction model is trained in the movie domain and then utilized to other domains. We evaluate the quality of obtained sentiment vocabularies intrinsically. Finall...

متن کاملUDC 539.4 Solution of the First-Passage Problem by Advanced Monte Carlo Simulation Technique
Предложен модифицированный численный метод Монте-Карло для оценки надежности нелинейных конструкций, подвергнутых динамическому нагружению. Использование метода позволяет обобщить важные низковероятностные выборки для нелинейных динамических задач. Эффективность данного метода по сравнению с прямом методом Монте-Карло состоит в возможности определения нелинейного стохастического отклика в облас...
