Accurate ground-based estimation of the carbon stored in terrestrial ecosystems is critical to quantifying the global carbon budget. Allometric models provide cost-effective methods for biomass prediction. But do such models vary with ecoregion or plant functional type? We compiled 15 054 measurements of individual tree or shrub biomass from across Australia to examine the generality of allomet...
the effects of the plant growth promoter gibberellic acid (ga3) and plant growth retardant chlormequat chloride (ccc) on biomass and quality of angelica dahurica var.formosana plants were investigated employing physiological and biochemical methods. plants were sprayed with ga3 or ccc at rosette stage and coumarin content was analyzed by high performance liquid chromatography (hplc) after harve...
Accumulation of plant biomass (Mg ha(-1)) with calendar time (wk) occurs as a result of photosynthesis for green land-based plants. A corresponding accumulation of mineral elements (kg ha(-1)) such as nitrogen, phosphorus, and potassium occurs from the soil through plant roots. Field data from literature for the warm-season annual cotton (Gossypium hirsutum L.) are used in this analysis. The ex...
Plant-herbivore interactions are influenced by host plant quality which in turn is affected by plant growth conditions. Competition is the major biotic and nutrient availability a major abiotic component of a plant's growth environment. Yet, surprisingly few studies have investigated impacts of competition and nutrient availability on herbivore performance and reciprocal herbivore effects on pl...
A combined heat and power virtual plant (CHP-VPP) can effectively control the distributed resources in an electric–thermal coupling system solve problem of lack flexibility caused by large-scale renewable energy grid connection. Similar to optimal reconfiguration distribution network topology operating switches, district heating is also equipped with tie sectionalizing valves realize adjustment...
Effect of fertilizer applications and grazing exclusion on species composition and biomass in wet meadow restoration in eastern Washington. Fertilizer applications and grazing exclusion were used as restoration strategies in degraded wet meadows in eastern Washington to grow biomass in the root systems where it could not be grazed. We used a split-block design to test vegetation responses to si...
Combined heat and power (CHP) production in combination with a district heating (DH) grid gives an energy-efficient use of wood fuels. The demand the DH will, however, decline coming decades, operators are seeking additional sinks. In this case study, integration pyrolysis unit into existing CHP plant was investigated as possible solution. retrofitted makes excess yields liquid bio-oil. Pyrolys...
This paper presents a technical description and characteristics of heat accumulation system operation in one the Polish combined power (CHP) plants. The total thermal capacity nonpressure hot water accumulator is 75 MWh. An important issue case tanks stratification caused by difference density between higher-temperature water, located top storage tank colder its bottom. article results numerica...
This paper describes a complete and stable version of CHP and the simulator CHPsim. CHP is a language for fine-grain distributed computation with asynchronous VLSI as its main application. Several partial versions of the language are already widely used, but CHP has never been presented as a complete language. This presentation includes constructs like meta process, connect statement, value pro...
