[1] Interphase mass transfer in variable aperture fractures occurs in many problems where two immiscible fluids are present, such as dissolution of dense nonaqueous phase liquids into groundwater, dissolution of CO2 in deep saline aquifers, and evaporation of trapped water by flowing gas during natural gas production. Typically, one fluid is entrapped by capillary forces and resides in immobili...

Gregarines, parasitic protozoa of invertebrates, possess a highly differentiated cell surface, with three cortical membranes and associated structures. Transmission electron microscopy and freeze-fracture reveal the presence of two cytomembranes lying uniformly under the plasma membrane. The density and the distribution of the intramembraneous particles (IMPs) in the plasma membrane of Gregarin...

Fusion of plasma membranes between Chlamydomonas reinhardtii gametes has been studied by freeze-fracture electron microscopy of unfixed cells. The putative site of cell fusion developes during gametic differentiation and is recognized in thin sections of unmated gametes as a plaque of dense material subjacent to a sector of the anterior plasma membrane (Goodenough, U.W., and R.L. Weiss. 1975.J....

In order to investigate the mechanical properties of developed wrought γ'-hardened Ni-based superalloy, LESS alloy (Low Eta Sigma Superalloy), and understand deformation behavior, tensile tests were carried out from room temperature 800oC in comparison with IN 740H alloy. Like other superalloys, found be dependent on temperature. As rose between 700oC, ultimate strength (UTS) decreased slightly...

In this work, a new design principle, i.e. doping with refractory metal particles low diffusion rate to prevent the formation of cracks and improve mechanical properties bulk metallic glass (BMG) composites, was put forward. It proven that crack-free dense Mo(p)/Cu47Zr47Al6 BMG composites enhanced can be produced via LPBF. The dislocations generated in Mo release thermal stress, thereby inhibit...

community detection is a task of fundamental importance in social network analysis. community structures enable us to discover the hidden interactions among the network entities and summarize the network information that can be applied in many applied domains such as bioinformatics, finance, e-commerce and forensic science. there exist a variety of methods for community detection based on diffe...

In this study, a set of laboratory experiments was carried out to study the parameters hydraulic fractures induced in dry and mineral-oil-saturated rocks compare them with geomechanical characteristics tested samples. We chose sandstone thermally treated granite as materials for research. There are very few known studies related mechanical acoustic properties oil-saturated rocks, even fewer des...

a 3-year-old arabian colt was presented for a major gingiva wound at the right rostral part of mandible. after clinical assessments, rostral mandibular fracture was determined. stabilization of fractured region was achieved via cerclage wire application under general anesthesia. fixation wires were left in place for 6 weeks. a 3 -month follow up revealed complete fracture healing. the purpose o...

absractall perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. the most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. the reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...
