Effective SLAs are extremely important to assure business continuity, customer satisfaction and trust. The metrics used to measure and manage performance compliance to SLA commitments are the heart of a successful agreement and are a critical long term success factor. Lack of experience in the use and automation of performance metrics causes problems for many organizations as they attempt to fo...

The Service Level Agreement (SLA) based grid superscheduling approach promotes coordinated resource sharing. Superscheduling is facilitated between administratively and topologically distributed grid sites by grid schedulers such as Resource brokers. In this work, we present a market-based SLA coordination mechanism. We based our SLA model on a well known contract net protocol. The key advantag...

The titanium implant surface was sandblasted with large grits and acid etched (SLA) to increase the implant surface for osseointegration. The topography of the titanium surface was investigated with scanning electron microscopy (SEM) and a profilometer. The SLA implant demonstrated uniform small micro pits (1-2 microm in diameter). The values of average roughness (R(a)) and maximum height (R(t)...

Grid technologies have reached a high level of development, however core shortcomings have been identified relating to security, trust, and dependability of the Grid which reduce its appeal to potential commercial adopters. Users require a job execution with a desired priority and quality. In order to stipulate such requirements, Service Level Agreements (SLA) can be negotiated. These are a pow...

in this paper, new features of satellite configuration, such as ip network  based infrastructure and separated signaling and media  are considered to propose a variety of satellite configurations in different orbits. because of their  different altitude in space such as low earth orbit(leo) and geostationary orbit (geo). a test bed used to test call setup delay in a one space link to process th...

The class I major histocompatibility complex (MHC) presents self-developed peptides to specific T cells to induce cytotoxity against infection. The MHC proteins are encoded by multiple loci that express numerous alleles to preserve the variability of the antigen-presenting ability in each species. The mechanism regulating MHC mRNA and protein expression at each locus is difficult to analyze bec...

Monocytes play an essential role in the defense against bacterial pathogens. Bone marrow (BM) and peripheral blood (PB) monocytes in pigs consist of the main "steady-state" subpopulations: CD14 hi/CD163-/SLA-DR- and CD14 low/CD163+/SLA-DR+. During inflammation, the subpopulation of "inflammatory" monocytes expressing very high levels of CD163, but lacking the SLA-DR molecule (being CD14 low/CD1...

Dengue virus RNA-dependent RNA polymerase specifically binds to the viral genome by interacting with a promoter element known as stem-loop A (SLA). Although a great deal has been learned in recent years about the function of this promoter in dengue virus-infected cells, the molecular details that explain how the SLA interacts with the polymerase to promote viral RNA synthesis remain poorly unde...

Plant communities can respond to environmental changes by altering their species composition and by individuals (within species) adjusting their physiology. These responses can be captured by measuring key functional traits among and within species along important environmental gradients. Some anthropogenic changes (such as fertilizer runoff) are known to induce distinct community responses, bu...
