Omega-categories and Chain Complexes
There are several ways to construct omega-categories from combinatorial objects such as pasting schemes or parity complexes. We make these constructions into a functor on a category of chain complexes with additional structure, which we call augmented directed complexes. This functor from augmented directed complexes to omega-categories has a left adjoint, and the adjunction restricts to an equ...
متن کاملLong-Chain Omega-3 Oils–An Update on Sustainable Sources
Seafood is currently the best and generally a safe source of long-chain (LC, (≥C(20)) omega-3 oils amongst the common food groups. LC omega-3 oils are also obtained in lower amounts per serve from red meat, egg and selected other foods. As global population increases the opportunities to increase seafood harvest are limited, therefore new alternate sources are required. Emerging sources include...
متن کاملsingle-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولSimple omega-categories and chain complexes
The category of strict omega-categories has an important full subcategory whose objects are the simple omega-categories freely generated by planar trees or by globular cardinals. We give a simple description of this subcategory in terms of chain complexes, and we give a similar description of the opposite category, the category of finite discs, in terms of cochain complexes. Berger has shown th...
متن کاملEffects of salt stress on total lipid values, fatty acid profiles, omega-3, omega-6 and omega-9, in the brown algea Sargassum boveanum on Bushehr coast
Some algae are rich sources of various beneficial lipids and fatty acids. In recent years, several studies have been performed on algae to evaluate the effect of different salinity treatments on the quantity and quality of these lipids. The present study was performed to investigate the effect of different concentrations of sodium chloride on total lipid content, fatty acid profile, and omega-3...
