Rooster Collagen Extracts from Rooster By-Products
Collagen associated hydrolysates have desirable characteristics for various industrial applications [1,2]. They have been used as important biomaterial in medical applications because of their biodegradability and weak antigenicity [3]. In addition, intracellular and extra-cellular self-assembly of polypeptide chains and the cross-links between adjacent molecules help collagen fibrils to withst...
متن کاملThe Rooster and the Butterflies
This paper describes a machine-checked proof of the JordanHölder theorem for finite groups. This purpose of this description is to discuss the representation of the elementary concepts of finite group theory inside type theory. The design choices underlying these representations were crucial to the successful formalization of a complete proof of the Odd Order Theorem with the Coq system.
متن کاملThe Rooster and the Syntactic Bracket
We propose an extension of pure type systems with an algebraic presentation of inductive and co-inductive type families with proper indices. This type theory supports coercions toward from smaller sorts to bigger sorts via explicit type construction, as well as impredicative sorts. Type families in impredicative sorts are constructed with a bracketing operation. The necessary restrictions of pa...
متن کاملCryopreservation of rooster sperm using methyl cellulose.
Experiments were designed to determine when, during the cryopreservation process, sperm lose fertilizing capacity and whether the cryoprotectant, methyl cellulose (MC), could be used in combination with glycerol to cryopreserve sperm and remain in the inseminate without reducing fertility. Semen diluted in Minnesota Avian extender (MNA) and inseminated immediately had greater fertility (75%) th...
متن کاملCellular content and biosynthesis of polyamines during rooster spermatogenesis.
The natural polyamines spermine and spermidine, and the diamine putrescine, were extracted from rooster testis cells separated by sedimentation at unit gravity, and from vas-deferens spermatozoa. The ratios spermine/DNA and spermidine/DNA were kept relatively constant throughout spermatogenesis, whereas the ratio putrescine/DNA rose in elongated spermatids. The cellular content of spermine, spe...
