The study was couducted to investigate the effects of gamma irradiation and CO₂ on flavonoid content and leaf gas exchange in C.asiatica. For flavonoid determination, the design was a split split plot based on Randomized Complete Block Design (RCBD). For other parameters, the designs were split plots. Statistical tests revealed significant differences in flavonoid contents of Centella asiatica ...

Uncertainty surrounds belowground plant responses to rising atmospheric CO₂ because roots are difficult to measure, requiring frequent monitoring as a result of fine root dynamics and long-term monitoring as a result of sensitivity to resource availability. We report belowground plant responses of a scrub-oak ecosystem in Florida exposed to 11 yr of elevated atmospheric CO₂ using open-top chamb...

As governments forced electricity producers to use more renewable energy sources, over a hundred thermal power plants in high-income countries turned biomass as partial or complete replacement for coal. Is the co-firing technology appropriate Vietnam? To assess we build an integrated model simulating economics, environmental and social implications of blending 5% rice straw two existing coal Vi...

Abstract Coal-conversion technologies, although used ubiquitously, are often discredited due to high pollutant emissions, thereby emphasizing a dire need optimize the combustion process. The co-firing of coal/biomass in fluidized bed reactor has been an efficient way pollutants emission. Herein, new model designed Aspen Plus® simultaneously include detailed reaction kinetics, volatile compositi...

Abstract This work focused on the production of biomass briquette as a boiler fuel for sustainable steam power plant electricity generation. Most existing plants rely fossil fuels, which are nonrenewable and hazardous to environment. Biomass briquettes made with materials, renewable can serve source firing plant. Producing improved characteristics is still big challenge due varying materials. I...

A computer controlled semiclosed net CO(2) exchange measurement system, employing an infrared gas analyzer and mass flow controllers to inject pure CO(2) at preset rates, has been developed for measuring whole plant net CO(2) exchange and net C gain in a controlled environment (i.e. CO(2), light, and temperature). Data for tomato (Lycoperscicon esculentum cv Campbell 19 VF) and rose (Rosa hybri...

In spite of its natural sources, Turkey depends on other countries in terms of energy production, and a transfer from conventional fossil sources to sustainable energy sources is strongly necessary. Among the sustainable energy sources, biomass is the subject of this study. The characteristics, logistic aspects, environmental aspects, economical, legal and technical aspects are investigated in ...

It is known that plant growth promoting bacteria (PGPB) elicit positive effects on plant growth and biomass yield. However, the actual mechanism behind the plant-PGPB interaction is poorly understood, and the literature is scarce regarding the thermochemical pretreatability and enzymatic degradability of biomass derived from PGPB-inoculated plants. Most recent transcriptional analyses of PGPB s...

Abstract Biomass serves as an alternative energy solution for decarbonizing coal-fired power plants, which have been reactivated in several countries due to the global crisis. Oil palm waste, owing its abundant availability, holds significant potential a biomass fuel. This study aimed investigate combustion performance of various oil wastes comparison coal. is associated with ash-related proble...
