Background The prevalence of celiac disease (CD) is remarkably varied in Down syndrome(DS)patientscompared with other diseases.  This study aimed to assess celiac disease prevalence in Down syndrome children with and without congenital heart defects (CHD) and its comparison with controls. Materials and Methods This case-control study was performed at a single center on 132 participants in three...

In this paper, we present a concrete proof point, achieved after roughly two years of collaborative effort, resulting in substantially decreased time-to-silicon and improved semiconductor customer success. We describe a foundry package containing a unique Cadence evaluation test chip, available today, and fabricated using the 0.18um CMOS Tower Semiconductor process design kit, Tower standard-ce...

a thermodynamic analysis of the counter flow wet cooling tower (cwct) in the steelmaking unit of the khuzestan steel company (ksc) is performed in this paper. we evaluated both energy and exergy formulations for analyzing the heat and mass transfer, exergy and second-law efficiency in this cooling tower. the lewis factor le f is an indication of the relative rates of heat and mass transfer in a...

cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. this paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. the tower is filled with 6 type packing. in this study temperature and pressure drop and tower characteristics was used in determining experimentally the ther...

We modelled the financial and environmental costs of two commonly used anaesthetic plastic drug trays. We proposed that, compared with single-use trays, reusable trays are less expensive, consume less water and produce less carbon dioxide, and that routinely adding cotton and paper increases financial and environmental costs. We used life cycle assessment to model the financial and environmenta...

Shortcut methods are valuable tools in the early stages of chemical process design, where numerous flowsheet alternatives need to be evaluated to determine the most energy-efficient, feasible flowsheet. Various shortcut methods based on tray-to-tray calculation and pinch point analysis for the inspection of feasibility and the determination of the minimum energy demand (MED) for homogeneous non...

The TraY protein is required for efficient bacterial conjugation by Escherichia coli F factor. TraY has two functional roles: participating in the "relaxosome," a protein-DNA complex that nicks one strand of the F factor plasmid, and up-regulating transcription from the traYI promoter. The traY gene was cloned, and the TraY protein was expressed, purified, and characterized. TraY has a mixed al...

Stroke patients may develop personal neglect, peripersonal neglect or both. Four new measures were tested in a sample of 42 right-handed inpatients (25 male; 17 female, median age 72 years). Participants removed keys from a rack, identified grocery items, washed their face, and cleaned a tray. Prior to this, they were classified as: no neglect (15), personal neglect (8), peripersonal neglect (7...

PURPOSE To compare the extent of tibial bone covered by the tibial tray in 6 most commonly used total knee arthroplasty designs in order to strike a balance between mediolateral cortical fit and optimal tibial component rotation. METHODS In 74 men and 27 women aged 17 to 60 (mean, 32) years with suspected soft-tissue injuries, their magnetic resonance images of the knee in full extension were...

BACKGROUND Different factors such as impression techniques and materials can affect the passive fit between the superstructure and implant. The aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant definitive casts. MATERIALS AND METHODS Four internal hex implants (Biohorizons Ø4 mm) were placed on a metal maxilla...
