The uniform theory of diffraction (UTD) plus an imposed edge diffraction extension is used to predict the backscatter cross sections of dihedral corner reflectors which have right, obtuse, and acute included angles. UTD allows individual backscattering mechanisms of the dihedral corner reflectors to be identified and provides good agreement w?ith experimental cross section measurements in the a...

A challenge facing immunization registries is developing measures of childhood immunization coverage that contain more information for setting policy than present vaccine series up-to-date (UTD) rates. This study combined milestone analysis with provider encounter data to determine when children either do not receive indicated immunizations during medical encounters or fail to visit providers. ...

BACKGROUND Guangdong province attracted more than 31 million migrants in 2010. But few studies were performed to estimate the complete and age-appropriate immunization coverage and determine risk factors of migrant children. METHODS 1610 migrant children aged 12-59 months from 70 villages were interviewed in Guangdong. Demographic characteristics, primary caregiver's knowledge and attitude to...

OBJECTIVE The goal was to determine whether patient-held vaccination records improve vaccination rates. METHODS The public-use files of the 2004-2006 National Immunization Survey, a national, validated survey of households with children 19 to 35 months of age, were used. The main outcome was up-to-date (UTD) vaccination status (4 diphtheria-tetanus-acellular pertussis/diphtheria-tetanus vacci...

This paper examines the propagation of radio waves in so-called urban street canyons through formulations based on Geometrical Optics (GO) and Uniform Theory Diffraction (UTD). As this type environment comprises a flanked by tall buildings more or less equally spaced both sides (creating canyon-like morphology), estimating attenuation that signals may experience these scenarios is crucial to pl...

Appropriate formulation of the UTD diffracted field is important for propagation prediction. Among the wedge. diffraction solutions for nonperfectly conducting surfaces in the literature, exact formulations are mostly based on Maliuzhinets's derivation [1] and are computationally prohibitive for practical applications. On the other hand, heuristic formulations, modified from the UTD diffraction...

The Blood Transfusion Unit (UTD) of the Rokan Hulu Regional General Hospital (RSUD) has an important role to fulfill demand for blood from patients. Patients who need donation are patients with low hemoglobin levels. problem faced by UTD-RS is that they have not been able meet needs each patient's request optimally. reason because it predict will come. To see pattern and then determine appropri...

BACKGROUND Accurate classification of children's immunization status is essential for clinical care, administration and evaluation of immunization programs, and vaccine program research. Computerized immunization registries have been proposed as a valuable alternative to provider paper records or parent report, but there is a need to better understand the challenges associated with their use. T...

Isosteric heats and adsorption isotherms were measured for combinations of three alkanes (methane, ethane, propane) on a series of six high-silica zeolites (TON, MTW, UTD-1, MFI, FER, FAU). Three of these zeolites (TON, MTW, UTD-1) have one-dimensional channels, two (MFI, FER) have two-dimensional intersecting channels, and FAU has spherical cavities. Since the adsorbate molecules are nonpolar ...
