Abstract Electrochemiluminescence (ECL) is a powerful transduction technique with leading role in the biosensing field due to its high sensitivity and low background signal. Although intrinsic analytical strength of ECL depends critically on overall efficiency mechanisms generation, studies aimed at enhancing signal have mostly focused investigation materials, either luminophores or coreactants, while fundamental mechanistic are relatively scarce. Here, we discover an unexpected but highly...
Blood pressure lowering effect of low intensity aerobic training in elderly hypertensive patients. Med. Sci. Sports Exerc., Vol. 30, No. 6, pp. 818-823, 1998. Purpose: The purpose this investigation was to determine the 9 months on blood patients who were receiving antihypertensive medication. Methods: group (N = 13; mean age 75.4 ± 5.4 yr) agreed take part physical using a treadmill with an exercise at lactate threshold (LT) for 30 min three six times week months. rest 73.1 4.2 served as...
Pulled elbow is a common upper extremity injury in children. We present retrospective study of 2331 pulled cases examined our hospital over the last ten years. All pediatric patients with diagnosis from January 2002 to December 2011 were retrospectively reviewed according sex, age, affected arm, recurrence rate, mechanism and treatment outcomes. There no significant sex difference. The frequency peaked for both boys girls at 6 months 2 years age. left arm was more than right. rate 14%. In...
A lightning arrester with a series gap for transmission lines has been developed to prevent faults due lightning. It shown excellent performance since 1986 on 77 kV service in heavy regions. 275 also developed, and field test was started line 1988. The authors describe the requirements arresters lines, design concepts, specifications, operational records three years. gapped-type is considered most practical given existing technology. To obtain light small arresters, an ethylene-propylene...
Failure modes have been studied phenomenologically on a small-signal GaAs MESFET with 1mu m aluminum gate. Three major failure revealed, i.e., gradual degradation due to source and drain contact degradation, catastrophic damage surge pulse, instability or reversible drift of electrical characteristics during operation. To confirm the product quality assure device reliability, assurance program has designed incorporated in production line. A cost-effective lifetime prediction method is...
Electrolytic corrosion of suspension insulator hardware is a wellknown problem with HVDC lines. The development sacrificial zinc sleeved insulators to minimize these problems and the in-service experience them described. This based mainly on operation ±250-kV transmission line in New Zealand but includes information from USA Japan. paper also refers detailed investigation into mechanism electrolytic DC possibility developing an improved for use areas where contamination very heavy.
A 275 kV gapped type arrester was developed and tested on an EHV transmission line which is liable to be extensively affected once a fault occurs. The study followed by the development of 500 arrester, its field test existing started in September 1990. main characteristics are discussed, evidence corroborate applicability lines presented. series gap length reduced adopting optimal electrode configuration reasonable concurrence probability unit switching impulse, order design practicable for...
An automatic DNA fragment collector using capillary array gel electrophoresis has been developed. A sheath flow technique is used for not only detection but also collection of fragments. In a cell, the fragments separated by 16 capillaries independently into corresponding sampling capillaries. The fraction consists trays and each tray set beneath end to collect flow-through Certain are automatically sorted controlling movement according signals from system. experimentally two mixtures...

Although polymer insulators generally show superior insulation performance under contaminated and wetted conditions due to hydrophobicity on their surface, owing shortage of field experience, anti-contamination design criteria are not yet established. Presently the same for ceramic mostly adopted by considering as safety margin. In order establish rationalized insulators, authors made a fundamental investigation. They found: (1) roughly two times heavier contaminant deposits hydrophobic than...
Since the successful completion of Human Genome Project, increasing concern is being directed toward polymorphic aspect genome and its clinical relevance. A form single-strand DNA-conformation polymorphism analysis (SSCP) employing nondenaturing slab-gel electrophoresis (SGE) applicable to genetic diagnosis bladder cancer from urine samples. To bring this technique into routine practice, use capillary (CE) naturally favorable in terms speed automation. However, resolving power SSCP, a...
Using a combination of capillary electrophoresis (CE) and patterned fluorescence correlation spectroscopy (patterned FCS), we have developed new technique for performing electrophoretic analysis independently the initial length injected analyte plugs. In t histechnique, which is abbreviated as CE/patterned FCS, fluorescent molecules dispersed continuously in migrate through stationary interference pattern created by two intersecting excitation laser beams, their emission monitored. We prove...
Experimental studies are presented of the wave characteristics and associated plasma heating in a system composed two counterstreaming electron beams longitudinally magnetized inhomogeneous plasma. Such an injection makes potential strongly negative, produces cross-field current. Three types electrostatic instabilities excited by current, i.e., lower-hybrid instability, ion-cyclotron harmonic modified instability. As latter grow strongly, nonlinear mixing develops between them. Corresponding...
This paper covers the results of investigations various electrical characteristics 10-in porcelain suspension insulators with a semiconducting glaze. The runaway withstand voltage is shown almost proportional to number insulator units in string. To get an uniform distribution along string impedance should be lowered as increases. Runaway under adverse condition and margin against working are also examined. performance contaminated glaze cold switch-on quantitatively investigated.
A microarray chip containing human P450 isoforms was constructed for the parallel assay of their metabolic activities. The had microwells that contained vertically integrated and oxygen sensing layers. film made an organically modified silica (ORMOSIL) doped with tris(4,7-diphenyl-1,10-phenanthroline) ruthenium dichloride (Ru(dpp)3Cl2).
