This study is motivated by the practice of large iron and steel companies, which have steady and heavy demands for bulk raw materials such as iron ore, coal, limestone and so on. These materials are usually transported to a bulk cargo terminal by ships (or to a station by trains). Once discharged, they are moved to and stored in bulk material stock yard, waiting for retrieval for production use...

A new scheme of energy storage in single-quantum-well semiconductor lasers is analyzed. This scheme involves the storage of the majority of injected carriers in the continuum states of the surrounding bulk material, in which the carrier density is diluted and the higher-order carrier-density-dependent recombination processes are much smaller. This allows the inversion level to build up to a muc...

We present experimental measurements of the properties of a liquid “Fomblin” surface obtained by the quasielastic scattering of laser light. The properties include the surface tension and viscosity as functions of temperature. The results are compared to measurements of the bulk fluid properties. We then calculate the upscattering rate of ultracold neutrons (UCN) from thermally excited surface ...

We aimed to evaluate the color stability of bulk-fill and conventional composite resin with respect to thickness and storage media. Twenty specimens of a conventional composite resin (6 mm diameter and 2 mm thick) and 40 specimens of the bulk-fill Tetric EvoCeram composite resin at two different thicknesses (6 mm diameter and 2 mm thick or 4 mm thick, n = 20) were prepared. The specimens were s...

Large-scale, distributed computer systems are less reliable than their smallscale, non-distributed counterparts. A significant proportion of the reliability problems are due to the very poor scalability of manual storage management techniques—the reclamation of unused storage in particular. The bulk of automatic garbage reclamation in both message-passing and shared memory systems, with certain...

Above-ground perennial phytomass of Andalusian alfa grass steppes (7755·6 ± 1482 kg of dry matter ha (95% C.I.)) is clearly higher than phytomass density measured today in most alfa grass communities of the Maghreb because of low or inexistant present-day human-induced alterations and relatively favourable annual precipitation (370 mm) existing in these Spanish steppes. Total carbon storage mea...

As a kind of cost-efficient hydrogen storage materials with high hydrogen capacity and light weight, Mg-based alloys have attracted much attention. This review introduces an effective technique in producing bulk ultrafine-grained (UFG) Mg alloys and promoting its hydrogen storage property, namely, equal-channel angular pressing (ECAP). This paper briefly describes the technical principle of ECA...

Cocoyam tubers were subjected to two processing methods (fermentation and parboiling) and milled into flour. The samples were stored at 25°C, 35°C, and 45°C and analyzed at 2 weeks interval for 8 weeks for their nutritional, functional, and pasting properties. Data obtained were subjected to multiple analysis of variance. Storage period and its interactive effect with the processing methods had...

We consider the problem of bulk data transfers and bandwidth sharing in the context of grid infrastructures. Grid computing empowers high-performance computing in a large-scale distributed environment. Network bandwidth, which makes the expensive computational and storage resources work in concert, plays an active role on performance. Due to specific traffic patterns, network topology and appli...

Contacts of two phases, which allow for synergistic dissociative storage of a component in two space charge zones ("job-sharing storage"), are considered from the viewpoint of point defect thermodynamics. The respective relations between charge and component activity (chemical potential of the component) are derived, or - for more complex cases - the recipes for their derivation are given. Thes...
