First principle calculations were performed using Density functional theory within the local spin density approximation (LSDA) to understand the electronic properties of Au(100)+TBT system and compare the results with Au(100) and bulk Au properties. Band structure, the total DOS and charge density for these materials are calculated. We found that the HOMO for Au(100)+TBT becomes broader than Au...

Sediment samples from the coastal area of Asaluyeh harbor were collected during autumn and spring 2015. The acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) were measured to assess the sediment quality and potential ecological risks. The average concentrations (and relative standard deviation (RSD)) of AVS in the industrial sediments were 12.32 μmol/g (36.91) and 6.34 μmol...

Mobile worker’s presence and availability at mobile devices can be very crucial in enterprise collaborative environment due to the not-always-on nature of the mobile devices. We identify the key challenges in tracking the presence status of mobile device and user and in the integration of mobile devices with enterprise collaborative environment. We present the design ideas of a Presence-Enabled...

in the last years of the twentieth century and the early years of the twenty first century, globalization with all its aspects and effects, has laid a ground which has originated and/or deepened structural weaknesses of states, their inability to answer the citizens’ demands and functional crisis of states. formation of international institutions, international non-governmental organizations (n...

Though established quality control standards were maintained, the bioavailability of digoxin from Lanoxin tablets produced in the United Kingdom fell in 1969, and was restored in 1972. After 1.5 mg doses of representative batches, tablets made between 1969 and 1972 produced mean values for area under the 50 hours plasma concentration/time curve of 36.6 ng/ml/hr and four-day urinary excretion of...

the present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using markov birth-death process and probabilistic approach. in present paper, the feed water system consists of four subsystems. after drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...
