Networked Infrastructure systems deliver services and/or products from point to point along the network. Demand for the services provided by such systems is typically cyclic, creating inefficiencies in capacity utilization. Congestion pricing provides incentives to shift demand from peak time periods to lower demand periods. This effectively increases the capacity of the system without the need...

Internal friction and ultrasonic attenuation peaks associated with diffusionless phase transformations in alloys, such as thermoelastic martensites and others, were reviewed. They were discussed from the stand point of (1) Understanding the mechanism of the phase transformations and (2) Developing new alloy materials of high damping capacity for application to noise and vibration abatement. Pha...

The aim of this paper is to evaluate at a histopathological level the effect of the most commonly used copper (Cu) supplementation (15 mg/kg dry matter (DM)) in the liver of intensively reared beef cattle. This was done by a histochemistry evaluation of (i) the antioxidant capacity in the liver - by the determination of metallothioneins (MT) and superoxide dismutase (SOD) expression - as well a...

conclusions cu, zn and cr play a specific role in the pathophysiology of diabetic nephropathy. meanwhile in these patients, low serum levels of cu, zn and cr were not associated with factors such as drinking water. possible causes should be sought in other factors like urine, intervention factors in absorption and utilization and individual conditions. results mean ± sd levels of zn, cu and cr ...

 In automated manufacturing there is continuous interaction between humans and machines. The utilization of those resources affects the capacity of manufacturing processes and consequently the performance of manufacturing systems. This paper presents an approach that incorporates productivity analysis tools and techniques to explain how manufacturing resource utilization relates to capacity an...

Desulfurization of a commercial diesel fuel by different adsorbents was studied in a fixed-bed adsorber operated at ambient temperature and pressure. In general, the adsorbents tested for total sulfur adsorption capacity at breakthrough followed the order: AC/Cu(I)-Y Cu(I)-Y Selexsorb CDX (alumina) CuCl/ -Al2O3 activated carbon Cu(I)-ZSM-5. The best adsorbent, AC/Cu(I)-Y (layered bed of 15 wt %...

Binding of Cu(2+), Ni(2+) and Ag(+) ions to polyallylamine (PAA), polyethylenimine (PEI), poly(N-2-(2-pyridyl)ethylallylamine) (PEPAA), poly(N-2-(2-pyridyl)ethylethylenimine) (PEPEI), and N-2-(2-pyridyl)ethylchitosan (PEC) has been investigated using batch sorption experiments, spectrophotometric titration, ESR, and XPS to elucidate how the structure of polymer precursors affects the ion bindin...

This article is a selective theory-driven review that synthesizes recent neuroscience findings concerning mental workload during complex cognition from the perspective of a functional resource theory called 3CAPS, focusing on the concept of capacity utilization. Capacity utilization refers to the proportion of resources that is being consumed in a given time interval in a given cognitive system...

the revenue management concept and techniques are applied to model the coordination of supply chain elements. the fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. the output of the supply chain can be various products and thus it is measured in terms of ...
