Development of high performance concrete using combinations of mineral admixtures. [PDF]
Cement replacement materials are by-products used to produce high performance concrete. Published data on the effects of combinations of mineral admixtures in concrete on the microstructural and performance-related properties under different ...

Structural details of dictyosomal pores [PDF]
Structural details of the dictyosomal pores in several plant cell types are described from tangential and cross sections of Golgi cisternae. Frequency distributions of the sizes of such Golgi pores are given and compared with the corresponding values of nuclear pores in the same cells.

The Structure of a Melittin-Stabilized Pore [PDF]
Melittin has been reported to form toroidal pores under certain conditions, but the atomic-resolution structure of these pores is unknown. A 9-μs all-atom molecular-dynamics simulation starting from a closely packed transmembrane melittin tetramer in DMPC shows formation of a toroidal pore after 1 μs.

Structure and Composition of the Fusion Pore [PDF]
Earlier studies using atomic force microscopy (AFM) demonstrated the presence of fusion pores at the cell plasma membrane in a number of live secretory cells, revealing their morphology and dynamics at nm resolution and in real time. Fusion pores were stable structures at the cell plasma membrane where secretory vesicles dock and fuse to release ...

Yield stress fluids method to determine the pore size distribution of a porous medium [PDF]
In this paper a new method is presented in order to determine the pore size distribution in a porous medium. This original technique uses the rheological properties of some non-Newtonian yield stress fluids flowing through the porous sample.

Poring over exosome structure [PDF]
The authors analyse the eukaryotic exosome structure, published in EMBO reports, in light of the known archaeal and prokaryotic exosomes, and discuss its striking flexibility and the conservation of the RNA channelling mechanism.

Structural insights into Clostridium perfringens delta toxin pore formation [PDF]
Clostridium perfringens Delta toxin is one of the three hemolysin-like proteins produced by C. perfringens type C and possibly type B strains. One of the others, NetB, has been shown to be the major cause of Avian Nectrotic Enteritis, which following the

Comprehensive characterization of nano-pore system for Chang 7 shale oil reservoir in Ordos Basin
Detailed study on the pore structure of shale oil reservoir is significantly for the exploration and development, and the conventional single pore structure measurement method cannot accurately describe the pore structure characteristics of the shale oil
