The ZK-Crypt combination compact hardware stream cipher engines each include a true random number generator, a stream cipher and a data authenticator based on a fast compact engine and proven "noise sources". The ZK-Crypt II 7.0 K gate and ZK-Crypt 8.2 K gate "engines" output a 32 bit word at each clock cycle with 128 and 160-bit keys, maximizing throughput with very low energy per enciphered b...

BACKGROUND AND AIMS Epidermal growth factor (EGF) is a potent mitogen for the gastrointestinal tract and also influences the number of new crypts formed by crypt fission. The time course of these events and possible linkage between these two complementary mechanisms is however poorly understood. We therefore examined the temporal relationship of proliferation and fission in rats treated with EG...

This paper introduces MD*Crypt as a means of distributing statistical methods and computing power. This paper explores MD*Crypt regarding topics of education. The role of MD*Crypt in projects associated with teaching statistics is examined. In an outlook, the potential of the MD*Serv/MD*Crypt architecture in frameworks of distributed computing and method providing is mentioned.

The impact of a challenge with moderately pathogenic <em>Escherichia coli</em> O128:C6 on the digestive physiology and gut bacterial community growing rabbits under two feeding programmes was analysed. Upon weaning (28 d old), 180 were allocated to four groups (9 cages 5 per group) for weeks: group C100 non-inoculated fed <em>ad libitum</em>; C70 feed intake limited 70% ...

This experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. One hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

The effect of 5-hydroxytryptamine (5-HT) on the crypt cell production rate in normal human duodenal mucosa cultured in vitro was studied using a stathmokinetic technique with crypt microdissection. The addition of 5-HT (2 mg/ml) to the culture medium significantly increased the crypt cell production rate (p less than 0.001), suggesting that this amine may have a trophic effect on crypt cells in...

This study assessed the effect of combination microencapsulated sodium butyrate (SB) and phytase (PH) on performance, intestinal integrity, bone development broilers. The experiment comprised 736 chicks distributed in a completely randomised design 2 × factorial scheme (with without inclusion SB with PH at recommended dose superdosing) totalling four treatments eight repetitions 23 birds each....
