The IEEE 802.15.3 is an ad hoc MAC layer suitable for multimedia WPAN applications and a PHY capable of data rates in excess of 20 Mbps. In 2.4 GHz unlicensed band, IEEE 802.15.3 specifies data rates up to 55 MBPS. It basically employs an ad hoc PAN topology, with roles for “master” and “slave” devices.In this work, it needs to determine the delay in discovering the devices by Pico Net Controll...

The role of pneumococcal (Pnc) surface adhesin A (PsaA) in the adherence of Streptococcus pneumoniae (pneumococcus) to host cells is not well defined. We examined the effect of anti-PsaA antibodies in an inhibition of adherence assay using Detroit 562 nasopharyngeal human epithelial cells. Rabbit polyclonal (Pab) anti-recombinant PsaA (rPsaA) sera, a purified mouse monoclonal antibody (MAb) (MA...

Lower respiratory tract infections (LRTI) are the leading cause of death world-wide, with Streptococcus pneumoniae (Pnc) as the most prevalent pathogen. Local immune mechanisms appear central to protection against the disease, yet they are poorly characterized. Infections at other, non-respiratory mucosal sites are associated with a transient circulation of mucosa-originating lymphocytes from t...

In this study, relationships between normalized difference vegetation index (NDVI) and plant (winter wheat) nitrogen content (PNC) and between PNC and grain protein content (GPC) were investigated using multi-temporal moderate-resolution imaging spectroradiometer (MODIS) data at the different stages of winter wheat in Linfen (Shanxi, P. R. China). The anticipating model for GPC of winter wheat ...

Streptococcus pneumoniae (pneumococcus [Pnc]) is a common bacterial agent found in mild mucosal as well as severe systemic infections. Local infections, such as acute otitis media, are rather common; every child has at least one during the first 2 years of life (1), and Pnc is the causative agent in approximately half of the bacterial culturepositive cases (2). Pneumonia is another disease ofte...

C-reactive protein (CRP) 1 is an acute phase serum protein produced rapidly in response to inflammatory stimuli. The binding and functional characteristics of CRP suggest that it may play a role in host defense against infection. CRP has binding specificity for the phosphocholine (PC) determinant of cell wall C-polysaccharide (PnC) from Streptococcus pneumoniae (1, 2). The binding of CRP to PnC...

I. I. Tupitsyn Institute of Physics, St. Petersburg State University, Uljanovskaya 1, Petrodvorets, 198504 St. Petersburg, Russia (Received 9 January 2001) We calculated the parity-nonconserving (PNC) 6s ! 7s amplitude in Cs. In the Dirac-Coulomb approximation our result is in good agreement with other calculations. Breit corrections to the PNC amplitude and to the Stark-induced amplitude b are...

Using semiclassical approximation we consider parity nonconservation (PNC) averaged over compound resonances. We demonstrate that the result of the averaging crucially depends on the properties of residual strong nucleonnucleon interaction. Natural way to elucidate this problem is to investigate experimentally PNC spin rotation with nonmonachromatic neutron beam: E ∼ ∆E ∼ 1MeV . Value of the ef...

The self-energy and vertex QED radiative corrections to the parity non-conservation (PNC) amplitude in atoms are obtained using the perturbation theory in powers of αZ. The calculated linear in αZ term gives −0.6% for the PNC amplitude in Cs. The estimated nonlinear terms make corrections larger −0.9(2)%. This result brings the experimental data for the 6s − 7s transition in 133 Cs in agreement...
