The Fine Structure of Mosquito Midgut Muscle
The midguts and associated muscle fibers of A. quadrimaculatus were dissected out in saline solution and immediately fixed in a solution of 1 % osmium tetroxide in 0.1 M potassium phosphate buffer, pH 7.2, for 5 min at room temperature. The specimens were subsequently dehydrated in ethyl alcohol for 2 hr and embedded in Epon 812 (Luft, 1961). Sections were cut on an LKB ultra microtome with gla...
متن کاملThree new species of free-living marine nematodes from East China Sea.
Three new species of free-living marine nematodes from intertidal sands in Xiamen, Fujian province are described and illustrated. Bathylaimus denticulatus sp. n. can be distinguished by a relatively small buccal cavity with its second part armed with two distinct teeth, short 2-3 μm labial and 12-16 μm cephalic setae and amphids of 0.8-0.9 turns. Oncholaimus minor sp. n. is characterized by its...
متن کاملBiodiversity patterns of free-living marine nematodes in a tropical bay: Cienfuegos, Caribbean Sea
Spatial and temporal biodiversity patterns of free-living marine nematodes were studied in Cienfuegos Bay, a tropical semi-enclosed basin in the Caribbean Sea. Taxonomic (to species level) and functional (biological trait) approaches were applied for describing the assemblage structure and relating it to abiotic environment based on a sampling scheme in six subtidal stations and three months. B...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
