Retarding Thick White Deterioration by Holding Shell Eggs in Sealed Containers

Modelling Sealed Containers in Z

Physical means of securing information, such as sealed envelopes and scratch cards, can be used to achieve cryptographic objectives, including ones that are hard or impossible by electronic means. So far, descriptions of such mechanisms have been informal, and as a consequence so has the associated reasoning. This paper3 takes a formal methods approach to these physical cryptography primitives....

Counteracting the Retarding and Inhibitory Effects of Strong Ultraviolet on Fucus Eggs by White Light

1. Strong dosages (20,000-50,000 ergs per mm.(2)) of ultraviolet light, predominantly of the wave-length 2537 A, greatly retard and inhibit the development of rhizoids in Fucus eggs irradiated at about 8 hours after fertilization. 2. If white light shines on the eggs after the irradiation by ultraviolet is terminated, the white light causes a considerable degree of recovery from the retarding a...

A setup for fast cooling of liquids in sealed containers

Wepresent a simple layout of a fast cooling system for liquids in sealed containers utilizing the large temperature gradients of cold nitrogen gas. Our system is optimized for about 20 cylindrical containers of 500 cm, but the setup allows for simple upand down-scaling aswell as the use of arbitrary containers.We have characterized the cooling performance of our system experimentally for temper...

Recovery of Salmonella from commercial shell eggs by shell rinse and shell crush methodologies.

Salmonella is the most important human pathogen associated with shell eggs. Salmonella Enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. Many sample methods are used to recover microorganisms from eggshells and membranes. A shell rinse and modified shell-and-membrane crush...
