This study assessed the provision of education and support to parents of children on home enteral nutrition (HEN), current dietetic support available and perceived challenges facing parents and carers. From the 39 responses (13%), 29 (83%, n = 35) parents suggested services for HEN need improvement. 29 (74%, n = 39) parents wanted more structured follow up and 22 (56%) would like one person to ...

Animals sense many environmental stimuli simultaneously and integrate various sensory signals within the nervous system both to generate proper behavioral responses and also to form relevant memories. HEN-1, a secretory protein with an LDL receptor motif, regulates such processes in Caenorhabditis elegans. The hen-1 mutants show defects in the integration of two sensory signals and in behaviora...

This study characterizes dynamic ammonia (NH3) and carbon dioxide (CO2) emissions associated with feeding and defecation activities of laying hens. Manure handling scheme used was reflective of commercial manure-belt house operation. Four dynamic emission chambers and measurement system was developed, featuring continuous measurement of the following variables for each chamber: (a) NH3 concentr...

We present high-resolution X-ray spectra of the nearby, multiple T Tauri star (TTS) system Hen 3-600, obtained with the High Energy Transmission Grating Spectrograph (HETGS) aboard the Chandra X-ray Observatory (CXO). Both principle binary components of Hen 3-600 (A and B, separation 1.4) were detected in the zeroth-order CXO/HETGS X-ray image. Hen 3-600-A — the component with a large mid-infra...

Hen antigonococcal lipopolysaccharide hen serum was used in a simple slide agglutination test for the identification of Neisseria gonorrhoeae from primary isolates.

In this article, we present the continuing work on a SARS model without quarantine by Hsu and Hsieh [Sze-Bi Hsu, Ying-Hen Hsieh, Modeling intervention measures and severity-dependent public response during severe acute respiratory syndrome outbreak, SIAM J. Appl. Math. 66 (2006) 627–647]. An “acting basic reproductive number” ψ is used to predict the final size of the susceptible population. We...

In a recent account of methods of obtaining best-fit parameters of the parameters V and Km of the Michaelis-Menten equation, Tseng & Hsu (1990) appear to have misunderstood the method used by Lineweaver & Burk (1934), and to have overlooked much of the work done since 1934. The Michaelis-Menten equation represents the observed rate of v of an enzyme-catalysed reaction in terms of the two parame...

Different stocking densities (SDs) or space allocations are being practiced in commercial laying-hen operations as an attempt to improve hen welfare. Information concerning the impact of SD on accumulated manure properties (e.g., moisture content) and thus ammonia (NH3) emissions is limited in the literature. Bird SD affects the amount of manure per unit of accumulated manure surface area, whic...

The objective of this observational field study was to investigate the effect of an alternative intermittent lighting program (13L: 5D: 1L: 5D – Trt) vs. standard lighting program (16L: 8D – Ctrl) on production performance of laying-hen parent flocks. Two houses of 15,000 Hy-Line brown parent-stock hens each were used for the comparative study. Hen-day egg production (HDEP), eggs per hen ho...

Microbial food safety of eggs has not been thoroughly investigated in Egypt. Pseudomonas species are among the most ubiquitous bacteria in the environment that may also contaminate eggs. To investigate the microbial burden of Pseudomonas species in eggs, one hundred composite samples (6 eggs in each) of table hen and duck eggs were prepares after they were collected from different shops and sup...
