  • tools for small hydropower Plant Resource planning and development a review of technology and applications
    Energies, 2011
    Co-Authors: Petras Punys, Antanas Dumbrauskas, Algis Kvaraciejus, G Vyciene
    Abstract:

    This paper reviews and compares software tools for the planning and design of small hydropower (SHP) Plants. The main emphasis is on small scale hydropower Resource assessment computer tools and methodologies for the development of SHP Plants corresponding to a preliminary or prefeasibility study level. The paper presents a brief evaluation of the historic software tools and the current tools used in the small hydro industry. The reviewed tools vary from simple initial estimates to quite sophisticated software. The integration of assessment tools into Geographic Information System (GIS) environments has led to a leap forward in the strengthening of the evaluation of the power potential of water streams in the case of the spatial variability of different factors affecting stream power. A number of countries (e.g., Canada, Italy, Norway, Scotland and the US) have re-assessed their hydropower capacities based on spatial information of their water stream catchments, developing tools for automated hydro-site identification and deploying GIS-based tools, so-called Atlases, of small-scale hydropower Resources on the Internet. However, a reliable assessment of real SHP site feasibility implies some “on the ground” surveying, but this traditional assessment can be greatly facilitated using GIS techniques that involve the spatial variability of catchment characteristics.

  • a review of polysaccharides from schisandra chinensis and schisandra sphenanthera properties functions and applications
    Carbohydrate Polymers, 2018
    Co-Authors: Zijian Li, Xin He, Jue Wang, Juan Feng
    Abstract:

    Abstract Schisandra is an herbal Plant Resource with dual functions in medicine and food since ancient times. It has a variety of healthcare and therapeutic effects. Schisandra chinensis (Turcz.) Baill and Schisandra sphenanthera Rehd. et Wits are two of the most commonly used Schisandra. Traditional Chinese medicine experience has shown that water-soluble polysaccharide from Schisandra may be one of its main components with pharmacological effects. Progress in the industrial production and extraction process of Plant polysaccharides, especially Chinese medicine polysaccharides in the past three decades, have led to many new discoveries about Schisandra polysaccharides in the fields of purification and identification. Their health benefits and pharmacological value have increased the interest of the public and academia. This review summarizes the physicochemical properties and biological functions of polysaccharides from two Schisandra fruits, and the application prospects of these bioactive macromolecules in future daily life and medicine.

  • flowers respond to pollinator sound within minutes by increasing nectar sugar concentration
    Ecology Letters, 2019
    Co-Authors: Marine Veits, Itzhak Khait, Uri Obolski, Eyal Zinger, Arjan Boonman, Aya Goldshtein, Kfir Saban, Rya Seltzer, Udi Bendor, Paz Estlein
    Abstract:

    Can Plants sense natural airborne sounds and respond to them rapidly? We show that Oenothera drummondii flowers, exposed to playback sound of a flying bee or to synthetic sound signals at similar frequencies, produce sweeter nectar within 3 min, potentially increasing the chances of cross pollination. We found that the flowers vibrated mechanically in response to these sounds, suggesting a plausible mechanism where the flower serves as an auditory sensory organ. Both the vibration and the nectar response were frequency‐specific: the flowers responded and vibrated to pollinator sounds, but not to higher frequency sound. Our results document for the first time that Plants can rapidly respond to pollinator sounds in an ecologically relevant way. Potential implications include Plant Resource allocation, the evolution of flower shape and the evolution of pollinators sound. Finally, our results suggest that Plants may be affected by other sounds as well, including anthropogenic ones.
