Abstract:
It was fairly often observed that <em>Fagus silvatica</em> L. leafed twice during one vegetational season. This secondary growth occurred on all trees, when the first leaves underwent destruction, e.g. in consequence of late spring frost. The leaves of secondary growth differed pronouncedly from normally developed ones by their shape and irregular nervation and were similar to the juvenile leaves of one-year-old seedlings of beech. Observations of leaf buds showed that the nerves appeared in leaf-primordia of <em>Fagus silvatica</em> as late as the latter part of July a

Stream networks and knickpoints in the Sanjiangyuan Region The source area of the Lancang (Mekong), Yangtze and Yellow rivers is named in Chinese Sanjiangyuan (source of three rivers). Geographical characteristics of these rivers, and various rivers at the margin of the Qinghai-Tibetan Plateau (Jialing, Minjiang, Dadu, Yalong and Jinsha) are summarized from field investigations along with digital elevation model (DEM) analyses and satellite images. Uplift of the Qinghai-Tibetan Plateau has resulted in an asymmetrical distribution of tributaries for stream networks at the margins of the plateau

Abstract:
The oeuvre of Sunčanica Tuk consists of pulsating, restless factures, composed of vertical, always different moves systematized in sequences, with paint often oozing from them owing to their nervation and pulsation. Her opus is a truly subtle and cultivated self-analysis, a sublime psychogram, something that transforms the artist’s mental state into an immediate human trace, suitable, as the painter says, “for the deepest contemplative dive” into the secrets of her undoubtedly spiritually rich being, for expressing her complex psychic constellation and mental tensions, neuralgia, even drama –

Abstract:
This paper provides the basics for more detailed research on the structures of bionic forms of different plant species and their application in the domain of landscape planning. The aim of this type of research is to expand knowledge of landscape planning with a deeper understanding of different geometric relations present in the existing natural forms. The correlation between structures in nature and structures that are present in contemporary landscape architecture could be established by the congruence with the geometric models from landscape. This paper is focused solely on the geometry of

OBJECTIVE: To test the application of the nerve-muscle pedicle (NMP) technique for selective rein-nervation of previously denervated posterior cricoarytenoid (PCA) muscle. METHODS: The left recurrent laryngeal nerve (RLN) was severed in 5 mongrel dogs, and an ansa cervicalis-sternohyoid muscle pedicle was sutured to the left PCA muscle. Three dogs underwent a sham operation. Videolaryngoscopy was performed, and electromyographic data were collected after 1 year on average. Finally, histologic analysis of the NMP was performed. RESULTS: The video records showed the return of mobility of the PCA

Abstract:
The asymmetrical leaf of Begonia raises both biological and mathematical questions. The leaf organogenesis of two species of Begonia is analyzed in this study, one with asymmetrical, palmately nerved leaves, Begonia scabrida A.DC, the other with quasi-symmetrical, pinnately nerved leaves, Begonia radicans Vellozo. Additional observations on Begonia fagifolia Fischer, a species of the second type, are included for comparison. In the three species studied, the leaf primordia are asymmetrical at initiation, notwithstanding mature leaf symmetry or nervation. In B. radicans, the leaf is asymmetrica

The indigenous component in Australian sorghums comprises 17 species and 1 variety of which 14 species and the variety are endemic, and 8 taxa are new. Sorghum brevicallosum is reduced to a synonym of S. timorense, which also includes S. australiense. Four previously established, subgenera are accepted with modified circumscriptions and floristic compositions. On morphological evidence, subgenus Stiposorghum represents the most advanced members and subgenus Para-Sorghum the most primitive. Some taxa are polymorphic; others exhibit unique features.

Abstract:
La nervation alaire est un marqueur morphométrique souvent utilisé dans l’étude des insectes. Son emploi est cependant restreint à des groupes d’organismes modèles ou limité par la collecte du matériel sur le terrain. L’exploitation des collections d’histoire naturelle permet d’élargir l’utilisation de ce marqueur à des études plus vastes. En tant qu’insectes sociaux de taille importante, bien représentés en collections quoiqu’encore relativement peu connus, les frelons (genre Vespa) constituent un sujet intéressant pour tester l’utilisation de la nervation alaire à différentes échelles de la

La nervation noire des crucifères, endémique au Québec depuis plusieurs années, est causée par Xanthomonas campestris pv. campestris. Cette bactérie occasionne des lésions jaunâtres en forme de"V" sur les feuilles de chou. Par ailleurs, l'agent responsable de la nécrose marginale de la laitue est Xanthomonas campestris pv vitians . Cette maladie se manifeste par l'apparition, en marge des feuilles, de taches d'apparence graisseuse devenant nécrotiques et confluentes. Les méthodes de répression chimique contre la nervation noire sont plus ou moins efficaces. En ce qui concerne la nécrose margin

L’hypothèse de canalisation d’une phytohormone, l’auxin, stipule que l’auto activation de son transport entre les cellules crée des chemins préférentiels qui se différencieront plus tard en système vasculaire. J’entreprends une analyse numérique de modèles de canalisation sur une grande matrice, et parviens à créer des motifs branchés dans lesquels circule l’auxin. Une analyse de stabilité d’un modèle simplifié nous éclaire sur les raisons de la formation de ces motifs et l’impossibilité de
