Abstract Buddleja globosa Hope is a well-known native, medicinal plant because of its digestive and cicatrizing properties. Due to the increasing domestic and international demand, B. globosa abundance and distribution in Chile has resulted in the intensive exploitation of the plant’s natural habitat, without consideration of the plant’s regenerative capacity. The main objective of this research was to establish the B. globosa growth cycle and model its regeneration cycle. This would allow for more productive, efficient and sustainable use and management of this species, thus ensuring its long-term conservation. We selected two study sites, one wild and another one cultivated. In… More >

Abstract Poa ligularis is an important forage in Patagonian rangelands. Populations of this perennial bunchgrass have been severely affected by overgrazing. We propose that increased defoliation frequencies will decrease (1) aerial- and belowground dry matter production, (2) root survival, and (3) concentration and content of total non-structural crown + root carbohydrates, and (4) increase root mortality. Five defoliation frequencies (plus 1 control) were applied in a representative grassland of the Occidental District in Patagonia during two consecutive growing seasons. All four hypotheses were rejected. Aerial and belowground dry matter production increased from one to two or three defoliations. Root production and… More >

Abstract Orchids of the genus Stanhopea are currently identified only by their floral structure characteristics. A statistical analysis of a significant number of species of this genus disclosed that measurements of adaxial and abaxial epidermal cell surface areas can be correlated with specific recognized species by a leaf printing method. This allows an objectively either positive or nearly positive confirmation of the identity of a species in the absence of flowers and without damage to plants. When ordering the mean values obtained for these surface areas in each species in a decreasing order, a correlation was observed in a hierarchical way… More >

Abstract The objective of this work was to study the effect of a controlled fire and/or roller-chopping on foliar cover and density of the most conspicuous woody and forage perennial grass species in the south of the Phytogeographical Province of the Monte, Argentina. All control treatments reduced the woody species mean percentage cover. This reduction persisted during the whole study period. Nevertheless, the woody species tended to recover their percentage cover towards the end of study. At the end of the study period, significant differences (P<0.05) were only detected between the control and controlled burn plus roller-chopping treatment. No significant differences… More >

Abstract Osteoarthritis (OA), with its high disability and mortality rate, is the most common arthritis throughout the world [1]. Exposure of articular cartilage to excessive mechanical stress is deeply involved in the pathogenesis of osteoarthritis (OA) [2,3]. However, the mechanism of how mechanical stress causes cartilage degradation is not clear yet. Here we report that bioinformatics-based integrative analyses can assist in the study of mechanisms modulated by mechanical stress within OA pathology, and we reveal that B-cell Translocation Gene 2 (BTG2) can be a mechanosensitive gene involved in OA development. We obtained OA-associated differentially expressed genes from human and rat datasets… More >

Abstract This paper deals with the performance of concrete specimens confined with different glass fabric reinforcement in organic binder consisting of resins. Three varieties of glass fabrics such as woven roving (WR), chopped strand mat (CSM), and textile reinforcement have been studied in the investigation. Experiments have been conducted on unconfined and confined concrete cylindrical specimens under compression. The effect of number of layers on confinement has been studied for specific cases. Specimens have been tested under displacement control. It is observed from the experiments that there is an increase in load carrying capacity as well as energy absorption capacity for… More >

Abstract Granular flow is commonly encountered in industry or nature, and is significantly affected by particle shapes. Super-quadric particles which can construct the geometric shape of irregular particles are simulated by the Discrete Element Method (DEM). In this study, the influence of aspect ratio and blockiness of particles on the flow characteristics is investigated, and the different discharge angles are used for different shaped particles to show the superposed effect of hopper configuration. Meanwhile, the Lacey mixing index is used to explore the effects of particle shapes on the mixing and motion of the granular system in a horizontal rotating drum.… More >
