This work aimed to investigate the impact of highest treatment temperature (HTT), heating rate, carrier gas flow rate and feedstock on the composition and energy content of pyrolysis gas to assess whether a self-sustained system could be achieved through the combustion of the gas fraction alone, leaving other co-products available for alternative high-value uses. Calculations based on gas compo...

Introduction ‘Count genes, not calories’ was the title of a nutrition article in the Financial Times of Friday, 13 June 2003. It referred to the results of the Human Genome Project and the discovery of our 35 000 genes, whose functions are currently both known and unknown. It also mentioned the study that painstakingly and systematically analysed all 17 000 genes of the Caenorhabditis elegans w...

This paper presents the ability of hybrid zero dynamics (HZD) feedback control method to reproduce human like movements for walking push recovery of an under-actuated 3D biped model. The balance recovery controller is implemented on a three-dimensional under-actuated bipedal model subjected to a push disturbance. The biped robot model is considered as a hybrid system with eight degrees of freed...

from the perspective of new growth models and new international trade theories, both exports and imports play an important role in a dynamic economy. economically, we cannot merely emphasize on a positive trade balance and we ignore the benefits of imports, and also we cannot advise negative trade balance. but the main concern of policy makers about international trade should be making stabilit...

Brain glucose sensing is critical for healthy energy balance, but how appropriate neurocircuits encode both small changes and large background values of glucose levels is unknown. Here, we report several features of hypothalamic orexin neurons, cells essential for normal wakefulness and feeding: (i) A distinct group of orexin neurons exhibits only transient inhibitory responses to sustained ris...

• Blood growth hormone (GH) concentrations increase shortly after calving. • Greater blood GH coordinates nutrient partitioning; the process through which nutrients are preferentially targeted for milk production. Blood insulin and insulin-like growth factor (IGF)-I remain low when blood GH concentrations increase. • Blood GH concentrations are elevated in cows in negative energy balance. Blood...

In this paper, a multi-zone modeling concept is proposed based on a simplified energy balance formulation to provide a better prediction of the indoor horizontal temperature variation inside the livestock building. The developed mathematical models reflect the influences from the weather, the livestock, the ventilation system and the building on the dynamic performance of indoor climate. Some s...

The continuous improvement of EAF performance is crucial for the increase in productivity and cost effectiveness and to render an environmental friendly process. RHI supports these targets by providing a diverse range of refractory and process solutions. Chemical energy in practical operation by injection of gaseous media like oxygen and natural gas, and solid materials like carbon have become ...

Energy conservation is one of the key priorities of sustainable development strategy. Transport systems are responsible for about one third of energy consumption. As result, the identification of solutions to reduce energy consumption in these systems is essential for the implementation of the sustainable development strategies. The present work is dedicated to identifying the possibilities for...
