The ` Egg - Yolk ' RepresentationOf Regions with Indeterminate
The paper proposes an approach to representing and reasoning about spatial regions with undetermined boundaries, using an adaptation of`RCC-theory', a region-based system for representing qualitative spatial relations developed over the last few years (Randell, Cui and Cohn 1992, Cohn, Randell and Cui 1994). The approach proposed is referred to as thèegg-yolk' representation: a region with unde...
متن کاملFreezing Bovine Sperm with Egg Yolk
Bull spermatozoa were pellet frozen on dry ice in a TES buffer containing combinations of egg yolk and glycerol to determine which component of an extender afforded cryoprotection to the spermatozoa. Neither buffer nor buffer plus glycerol protected sperm cell motility in the absence of egg yolk, while sperm cells frozen in egg yolk buffer in the absence of glycerol had 24% postthaw motility (P...
متن کاملSpecific Chicken Egg Yolk Antibodies against Enterotoxigenic Escherichia coli K99 in Serum and Egg Yolk of Immunized Laying Hens
Enterotoxigenic Escherichia coli K99 is one of the dominant pathogens associated with diarrhea of calves. Immunoglobulin Y (IgY), has been used as an inexpensive alternative to antibiotics for the prevention and therapy of several bacterial infections. The study aimed to prepare IgY antibodies against E. coli K99 and to investigate its in vitro effectiveness. E. c...
متن کاملProteins and Lipoproteins in Yolk from Eggs of the Estuarine Crocodile (crocodylus Porosus); a Comparison with Egg Yolk of The
1. The livetin patterns of the two species Crocodylus porosus and Gallus domesticus were very different and it was difficult to find a correspondence. 2. In C. porosus the granules were a larger proportion of the total yolk but they contained very little lowdensity lipoprotein when compared with granules from hens' eggs. 3. The low-density lipoprotein was a lower proportion of the yolk of C. po...
متن کاملEgg yolk plasma can replace egg yolk in stallion freezing extenders.
Hen egg yolk is normally used as a cryoprotective agent in semen freezing extenders, but its use has sanitary and practical disadvantages. Moreover the protection afforded by egg yolk has not yet been completely elucidated. The objective of this study was to compare the egg yolk plasma fraction to whole egg yolk in stallion freezing extender. Plasma contains mainly Low Density Lipoproteins (LDL...
