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...

Femtosecond laser ablation (FLA) has been playing a prominent role in precision fabrication of material because its circumvention thermal effect and extremely high spatial resolution. Molecular dynamics modeling, as powerful tool to study the mechanism femtosecond ablation, still lacks connection between simulation results experimental observations at present. Here we combine single-shot chirpe...

Objective: Peroxisome proliferator-activated receptors (PPARs), key transcriptional regulators of lipid and energy metabolism in cardiomyocytes, have recently been proposed to modulate cardiovascular pathophysiological responses in experimental models. However, there is little information about the functional activity of PPARs in human heart failure. Aims: To investigate PPAR-a and -g expressio...

conclusions our results demonstrated that r-fla-a could induce cellular and humoral immune response as proper stimulant of poly-isotypic humoral responses. results immunized mice with adjuvanted flagellin showed a considerably increased lymphocyte proliferation compared with the control group (p = 0.004). high level of il-4 and ifn-γ secretion was observed in immunized mice compared with the co...

This study was conducted during two successive seasons 2003 and 2004 by using twelve peach cultivars whether importedlow chill or originated as strains of local cultivar Meet Ghamr. Studied cultivars were either early-season ones (namely, Robin, Rubidoux, and Spring Time) or mid-season cultivars (namely, Florida Red, Fla 16/33, Fla 3/2, Desert Red, Bemto, and Hagazy) or late-season cultivars (n...

Speaking in a foreign language, which is often perceived as intimidating by many language learners, has long been associated with anxiety (FLA), particularly speaking (FLSA). Although numerous studies have investigated FLA and FLSA, most focused on the classroom environment, whereas settings outside classroom, where learners use to communicate native speakers foreigners, relatively overlooked. ...

There are four outcomes to feline coronavirus (FCoV) infection: the development of feline infectious peritonitis (FIP, which is immune-mediated), subclinical infection, development of healthy lifelong carriers and a small minority of cats who resist infection (Addie and Jarrett, Veterinary Record 148 (2001) 649). Examination of the FCoV genome has shown that the same strain of virus can produce...

Membrane fusion is a crucial step in flavivirus infections and a potential target for antiviral strategies. Lipids and proteins play cooperative roles in the fusion process, which is triggered by the acidic pH inside the endosome. This acidic environment induces many changes in glycoprotein conformation and allows the action of a highly conserved hydrophobic sequence, the fusion peptide (FP). D...
