OBJECTIVE To assess the validity of acoustic rhinometry for measuring nasal valve area in human subjects. STUDY DESIGN A comprehensive study that compared acoustic rhinometry data with computed tomography findings from scans obtained perpendicular to the acoustic axis and perpendicular to the floor of the nose. METHODS Fifty nasal passages of 25 healthy adults with no nasal disease were exa...

during early neurogenesis, the floor plate plays an essential role(s) in the differentiation of the ventral portion of neural tube. in this study, we detected the specific distribution of unique glycoconjugate during the floor plate differentiation. formalin fixed paraffin sections of balb/c mice (10-14 embryonic days) were processed for histochemical studies using horseradish peroxidase-labell...

When introduced to the laying facility, pullets are sometimes temporarily excluded from the litter area in order to help them locate food and water, and to prevent floor-laid eggs. This procedure is not permitted in Sweden, because it involves denying access to both litter and space, which may have a negative effect on bird welfare. The present study investigated how the welfare and performance...

BACKGROUND Use of protective footwear before entering the intensive care units is enforced with the assumption that it lowers the incidence of bacterial floor colonization. The present study was carried out to find the efficacy of protective footwear on bacterial floor colonization. METHODS The study was carried out in the intensive care unit of a tertiary care hospital. The study was divided...

Serious floor heave in gob-side entry retaining (GER) with fully-mechanized gangue backfilling mining affects the transportation and ventilation safety of the mine. A theoretical mechanical model for the floor of gob-backfilled GER was established. The effects of the mechanical properties of floor strata, the granular compaction of backfilling area (BFA), the vertical support of roadside suppor...

A preference testing apparatus was used to provide sows with continuous access to three identical farrowing crates, each with a different floor temperature. The concrete floor under each crate contained copper pipe through which temperature-controlled water was circulated to achieve unoccupied floor temperatures of 22 degrees C (+/-3.5), 29 degrees C (+/-1) and 35 degrees C (+/-1). Eighteen sow...

Introduction: After the lead poisoning outbreak came to light in Zamfara State, Nigeria, people living near gold mines were worried about environmental safety, especially drinking water quality. This study examined the gross alpha and gross beta activity concentrations in groundwater in different locations of Anka, Zamfara State, Nigeria, to measure the possible radiation dose and potential hea...

OBJECTIVE There is preliminary evidence linking long-term participation in high-impact exercise with poor performance in labor and increased incidence of stress urinary incontinence, which may be due to altered pelvic floor function. Recent work has shown that HIFIT (high-impact, frequent intense training) athletes have an increased cross-sectional area of the levator ani muscle group as visual...

nt matter & 2007 IAgrE. emseng.2007.07.007 hor. : [email protected] (B. Li) A concrete slatted floor system that consists of a narrow-gap slatted floor and beneath it a slope bottom for separation of faeces and urine in pig houses was investigated. In the experiments, four concrete slatted floors with one of two slat profiles and one of two gap widths, and a steel wire slatted floor were studied ...

There is a lack of studies on trip generation rates related to land use activities in developing countries. The absence makes transportation planners listed the Institute Transportation Engineers (ITE) Trip Generation Manual, which may lead unrealistic results. study aims determine attraction for banking services Zagazig city, Egypt, and evaluate factors affecting attracted trips banks. has des...
