BACKGROUND There is a need to determine parameters for the analyses of the distortion product otoacoustic emissions (DPOAE) of infants so that it can be used as a clinical criterion in auditory assessment. AIM To describe the DPOAE records of infants from birth to two months, considering the response level, noise level and the signal to noise ratio in all frequencies; the analysis of response...

BACKGROUND Hearing thresholds of fishes are typically acquired under laboratory conditions. This does not reflect the situation in natural habitats, where ambient noise may mask their hearing sensitivities. In the current study we investigate hearing in terms of sound pressure (SPL) and particle acceleration levels (PAL) of two cichlid species within the naturally occurring range of noise level...

A total of 60 Russ 2011 two weeks old broiler chicks with an average weight of 215.33+4.55g were fed with diets compounded with sweet potato leaves (SPL) for 56 days. The diets consist of T1 (0% SPL), T2 (5% SPL), T3 (10% SPL) and T4 (15% SPL). The proximate composition of the SPL was determined in the laboratory. The birds were randomly allocated to four treatments using completely randomized ...

The study of the SPL (Superconducting Proton Linac), a 4 MW / 2.2 GeV H linac, began at CERN in 1999. Based on the large inventory of RF equipment decommissioned from the LEP (Large Electron Positron collider), it was originally proposed as an upgrade to the injector complex for the high energy accelerators. Since that time, the proposal has attracted the interest of an increasing number of phy...

Hyperglycemia in diabetes alters tight junction (TJ) proteins in the kidney. We evaluated the participation of aldosterone (ALD), and the effect of spironolactone (SPL), a mineralocorticoid receptor antagonist, on the expressions of claudin-2, -4, -5 and -8, and occludin in glomeruli, proximal and distal tubules isolated from diabetic rats. Type 1 diabetes was induced in female Wistar rats by a...

This paper describes a new context for the application of domain-specific languages (DSL) and modeling techniques: that of product production in a software product line (SPL). It briefly describes SPLs and how their products are produced. It then describes the role of DSLs and methods engineering in SPL product production. Specifically, we combine meta-modeling and other domain specific languag...

This paper deals with deriving software products from a software product line (SPL) in an efficient and automated way. We present an approach that (1) represents the SPL with a set of integrated models, (2) specifies variability and configuration options for possible product variants and (3) automatically derives executable products with model transformations and aspect-oriented techniques. The...

Intercellular signalling mediated by Notch proteins is crucial to many cell fate decisions in metazoans. Its profound effects on cell fate and proliferation require that a complex set of responses involving positive and negative signal transducers be orchestrated around each instance of signalling. In Drosophila the basic-helix-loop-helix (bHLH) repressor encoding genes of the E(spl) locus are ...
