As one of the most environmentally friendly and cost-effective method, anaerobic digestion (AD) has been widely studied and developed as a conventional technology to degrade biodegradable materials and produce biogas simultaneously. Various substrate sources are used in this process such as organic fraction of municipal solid waste (MSW), waste activated sludge (WAS), animal manures, agro-indus...

In this scientific article, control sensors and devices have been improved based on the method of counting arrows rolling stock railway transport. The microprocessor-controlled unit system simplified to manage traffic between two stations, a self-monitoring, reliable risky scheme has developed. Wiring diagrams existing transport relays updated for uninterruptible power supplies, microprocessor ...

New combined optical/thermal method (optical DLTS) for the investigation of gap states is presented. The concentration and energy distribution of the gap states have been studied. The optical DLTS signal S(T) vs. temperature is calculated from the photoconductivity decay I(t,T). The effective levels and density of states for amorphous Se and As2Se3 films were obtained. Introduction.Recently, th...

Geological processes alter pore spaces over time, and their analysis can shed light on the dynamic fractal structure fluid flow of rocks time. This study presents experimental evidence to illustrate that evolves with sedimentation, carbonate cementation, clay growth, dissolution. It examines, describes characterizes a suite core samples from Gaotaizi oil layer second third members Qingshankou F...

author’s e-mail: [email protected] The extreme ultraviolet light source (EUVL) is being studied intensively toward its application in semiconductor technology [1]. Use of Mo/Si multilayer optics requires that the EUVL should produce emission at the 13.5 nm band with high efficiency (> 1%). Xe plasma has been considered as promising candidate, however, strong emission is usually obtained in...

Synapses are highly specialized structures that transmit information between neurons. When an action potential generated by a neuron reaches a presynaptic terminal, a cascade of events produces a flow of ionic currents into or out of the postsynaptic neuron’s membrane, with a characteristic time course that can last up to several hundreds of milliseconds.1 Modeling the detailed dynamics of post...

Computer graphics displays make it possible to display both the topological structure of a system in the form of a schematic diagram and information about its current state using color-coding and animation. Such displays should be especially valuable as user interfaces for decision support systems and expert systems for managing complex systems. This report describes three experiments on the co...

If future electronic documents are to be truly useful, we must devise ways to automatically turn them into knowledge bases. In particular, we must be able to do this for diagrams. This paper discusses biological diagrams. We describe the three major aspects of diagrams: visual salience, domain conventions and pragmatics. We next describe the organization of diagrams into informational and subst...

In the 1970s, O'Keefe and Dostrovsky discovered that certain neurons, called place cells, in an animal's brain are tied to its location within arena. A combinatorial neural code is a collection of $0/1$-vectors which encode patterns co-firing activity among cells. Gross, Obatake, Youngs have recently used techniques from toric algebra study when $0$- $1$-, or $2$-inductively pierced: property a...
