The Efficiency of Linda for General Purpose Scientific Programming

, however, are of little value unless Linda programs execute efficiently. The goal of this article is to demonstrate that Linda programs are efficient making Linda an effective general purpose tool for ... interaction of processes). In Linda, coordination takes place through six oper­ ations that manipulate an associative, virtual shared memory. This coordination mechanism is both simple and general making it

Physics in daily life: seeing under water

in the treatment, there are interesting results that indicate that the singularity problem of classical general relativity would be resolved due to the fundamental discreteness predicted by LQG ... . Another important open issue in LQG is the semiclassical limit: how to recover from the fundamental polymer-like excitations of LQG the smooth physics of general relativity and the standard model at low

Water makes glass elastically stiffer under high-pressure

and synthesis condition have so far been extensively tested to meet this requirement. Since hydration of matter, in general, significantly reduces its stiffness, it has long been believed that an ... previously reported in anhydrous silica glass, implying that water is a highly effective impurity to make SiO2 glass much denser. This experimental discovery strongly indicates that hydration combined with

Reversible Thermoassociation of Water-Soluble Polymers

In various industrial fields, water soluble polymers are commonly used as thickening agents to control the reology of aqueous fluids. Nevertheless, their properties are weakened as the temperature ... weakened as the temperature increases. In order to overcome this problem, the concept of “ther­ moassociative”water soluble polymers was developed. Such new amphilic systems can be obtained by grafting on an

Liana and tree below-ground water competition—evidence for water resource partitioning during the dry season

dual stable water isotope approach (δ18O and δ2H) enables below-ground vegetation competition for water to be studied. Based on the occurrence of a natural gradient in soil water isotopic signatures ... more general trait for lianas than for trees has never been studied. Further research on this topic is greatly needed and should be considered in view of the presented findings. Seasonality in water use

Evaluation of Physicochemical Characteristics of Various River Water in India

Physicochemical parameters of water samples collected from various rivers in India. Water samples under investigations were collected from Krishana Vijaywada, Gomti Lucknow, Hoogali Kolkata, Ganga ... drinking purposes while for other uses like agriculture and industry, the quality of water can be quite flexible and water polluted up to certain extent in general sense can be regarded as pure4. Industrial

Water quality management through community engagement in Costa Rica

Concerns about stream water quality are increasing in Latin America. Poor sanitation infrastructure coupled with a high demand from agricultural development, recreational use, drinking, and ... involvement, along with a water quality index useable by the general public, was a key to the overall success of the project.

Assessment of Ground Water Quality in and around Gobichettipalayam Town Erode District, Tamilnadu

Ground water samples collected from different localities in and around Gobichettipalayam town, Erode District, Tamil Nadu were analyzed for their physico- chemical characteristics. This analysis ... Gobichettipalayam area were analyzed for general water quality, pollution due to industrial discharges and pollution due to municipal sewage. Hence, it is highly essential to examine the presence of toxic substances

Feasibility of 15O-water PET studies of auditory system activation during general anesthesia in children

not able to cooperate during scanning. Therefore, we evaluated retrospectively results of individual SPM (statistical parametric mapping) analysis of 15O-water PET in 17 children studied during general ... auditory cortex activations in 15O-water PET during general anesthesia. Combined with the improved signal to noise ratios of modern PET scanners, this suggests reasonable prospects for further evaluation of

Data Quality from a Community-Based, Water-Quality Monitoring Project in the Yukon River Basin

This paper examines the quality of data collected by the Indigenous Observation Network, a community-based water-quality project in the Yukon River Basin of Alaska and Canada. The Indigenous ... retrospective analysis of a set of water-quality parameters reported by all three projects over a number of years. No statistical differences were found among the three projects for pH, Calcium, Magnesium, or

Regulation of water resources systems using fuzzy logic: a case study of Amaravathi dam

Regulation of a water resource system is one of the challenging tasks due to uncertainty involved in demand and supply. It may be due to changes in the climatic conditions, living standards of people ... many real-life applications. In general, a water resources system has a large set of data which require careful analysis for taking appropriate decisions pertaining to water allocation, quality and

Dirty Water: ‘Nuremberg’ and Film
