The gonad of Helix aspersa contains a factor which can stimulate in a dose-dependent manner galactogen synthesis in albumen gland explants cultured in vitro. The stimulatory activity appears to be greater when the gonad is predominantly male than when it is predominantly female. The albumen gland of virgin snails does not respond in vitro to the gonadal influence. The receptivity of the albumen...

Industry observations indicate that a proportion of shell eggs exhibit an uncharacteristic spreading of the thin albumen when they are broken-out for fast-food preparation. Because the height and characteristics of the thick albumen are unaffected, the eggs are classified as Grade A. Preliminary observations discounted effects of egg storage or contaminated feed. Two experiments were conducted ...

In the maximum constraint satisfaction problem (Max CSP), one is given a finite collection of positive-weight constraints on overlapping sets of variables, and the goal is to assign values from a given domain to the variables so that the total weight of satisfied constraints is maximized. We consider this problem and its variant Max AW CSP where the weights are allowed to be both positive and n...

Additive Manufacturing offers geometric freedom excellently suited for topology optimized light weight designs. Ideally these should be produced from materials of high strength to weight ratio such as aluminium-copper alloys. Yet these are considered unsuitable for welding. With Laser Beam Melting of Metals in powder bed (LBM), the only class of aluminium alloys widely processed is that of alum...

A 3 x 3 treatment arrangement varying in dietary protein and TSAA:Lys was used to evaluate the effect of low-protein diets fed to Hy-Line W-98 laying hens. Phase I was 20 to 43 wk of age with 18.9, 17.0, and 14.4 g of protein/hen per day and 0.97, 0.85, and 0.82 TSAA:Lys, whereas phase II was 44 to 63 wk of age with 16.3, 14.6, and 13.8 g of protein/hen per day and 0.92, 0.82, and 0.72 TSAA:Lys...

The aim of the current study was to investigate effect different storage period on some external and internal egg quality ovalbumin levels goose eggs. alterations these traits have not been examined sufficiently in eggs during storage. For this purpose, a total 150 were from 50 weeks-old German origin Embden geese. stored under constant temperature (+4°C) ~ 60-65% relative humidity conditions f...

was 140/90 and her haemoglobin was 15.9 g. per cent. There was no evidence^, complications of diabetes apart from absence of the deep reflexes of the lower She was found to have a urinary infection, her urine containing albumen, puS and coliform bacilli. This was eradicated by means of sulphonamides. Her diabetic state was treated with a free diet and protamine zinc insulin 30 the morning. She ...

Recently, some nondestructive methods for the assessment of albumen freshness were developed. Among others, visible near-infrared transmission spectroscopy and low-resolution proton nuclear magnetic resonance (LR (1)H NMR) measurements were proposed. This study was performed to evaluate the potential of the combined measurement of visible near-infrared transmission spectroscopy and LR (1)H NMR ...

Relationships between egg size, egg components, and neonate size have been investigated across a wide range of oviparous taxa. Differences in egg traits among taxa reflect not only phylogenetic differences, but also interactions between biotic (i.e., maternal resource allocation) and abiotic (i.e. nest environment conditions) factors. We examined relationships between egg mass, egg composition,...
