We have studied the angle-resolved energy distribution of spin-polarized electrons emitted during ion-surface scattering. At clean Fe surfaces, electron spin polarization values (ESP) of up to 48% are found. Varying the scattering angle of the ions from 1 ° to 45 °, we find that the layer-dependent, average ESP at the topmost surface layer is enhanced by 32% compared to that of the bulk and tha...

ESP and AH protocols make use of various cryptographic algorithms to provide confidentiality and/or data origin authentication to protected data communications in the IP Security (IPsec) architecture. To ensure interoperability between disparate implementations, the IPsec standard specifies a set of mandatory-toimplement algorithms. This document specifies the current set of mandatory-to-implem...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

Control of Particulate matter (PM) emission is a key pollution issue affecting the environment and human health, especially sizes that range below 10 μm. The objective of this work is to develop a dust flow separator type electrostatic precipitator (DFS-ESP) for the effective control of fine particulate matter emission from natural gas combustion. An experiment was conducted for natural gas com...

The recently developed ESP Culture System II (AccuMed, Chicago, Ill.) was compared with radiometric BACTEC 460TB (Becton Dickinson, Towson, Md.) and with Lowenstein-Jensen medium for recovery of mycobacteria from over 2,500 clinical specimens both of respiratory and nonrespiratory origin, including blood. The majority of the 219 mycobacterial isolates (129) belonged to the Mycobacterium tubercu...

The status of teaching ESP has been studied both internationally and locally. However, it seems that the challenges of teaching ESP in medical universities of Iran have not been studiedappropriately. The main objective of the present study was to explore the main challenges of teaching ESP in medical universities of Iran. Due to the nature of the study, a qualitative res earch design (Phenomeno...

The adipocyte-derived hormone leptin regulates appetite and bone mass. Recent research demonstrates that reciprocally, osteoblasts have a role in controlling energy metabolism. Several genes expressed in osteoblasts are involved in this process, and one of them is the Esp gene. The remaining genes regulate Esp gene expression. OST-PTP, the protein name of Esp, regulates the carboxylation of ost...

One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader fleet. This problem is the Equipment Selection Problem (ESP). In this paper, we describe the ESP in the context of surface mining. We discuss related problems and applications. Within the scope of both the ESP and related problems, we outline modeling and solution approaches. Using...
