Laboratory parameters can contribute to the diagnosis of asthma, which is often a difficult procedure in paediatric patients. The aim of this study was to investigate the value of eosinophil cationic protein (ECP) and eosinophil-derived neurotoxin (EDN) in the diagnosis of paediatric asthma. The number of eosinophils, serum ECP and EDN, and urinary EDN were determined in 22 children with stable...

Purkinje cell toxicity is one of the characteristic features of the Gordon phenomenon, a syndrome manifested by ataxia, muscular rigidity, paralysis, and tremor that may lead to death (Gordon, 1933). Two members of the RNase superfamily found in humans, EDN (eosinophil-derived neurotoxin) and ECP (eosinophil cationic protein), cause the Gordon phenomenon when injected intraventricularly into gu...

The paper deals with the mechanical behavior of a micro-beam bonded with two piezoelectric layers. The micro-beam is suspended over a fixed substrate and undergoes the both piezoelectric and electrostatic actuation. The piezoelectric layers are poled through the thickness and equipped with surface electrodes. The equation governing the micro-beam deflection under electrostatic pressure is deriv...

Electric distribution networks have a simple protection system including fuses, re-closers, and overcurrent relays. One of the negative effects of DG installation in distribution network is miscoordination of protection devices and conflict between DG operation as islanding mode and protection purposes. This paper for overcoming to this difficulty proposes an efficient algorithm based on dividi...

Reliable electrical power supply is a prerequisite for the modernsociety, and if it fails, it can cause severe consequences in terms of economiclosses and even fatalities. It is thus important to analyse the vulnerabilityof the electric power system. Network analysis has previously been used toanalyse the vulnerability of electric transmission systems. Recent events inSweden...

Growing integration of distributed energy resources (DER) presents the electric power sector with the potential for significant changes to technical operations, business models, and industry structure. New physical components, control and information architecture, markets, and policies are required as the power system transitions from one of centralized generation and passive load to a network ...
