INTRODUCTION The objective of this study is to provide a synthesis of the pertinent design criteria for submerged bendway weirs. The technical paper is an extension of previous research conducted by the National Center for Computational Hydroscience and Engineering (NCCHE) at the University of Mississippi on the hydrodynamic effects on flow characteristics and effectiveness of submerged bendway...

BACKGROUND Today, implants are placed using both non-submerged and submerged approaches, and in 1- and 2-piece configurations. Previous work has demonstrated that peri-implant crestal bone reactions differ radiographically under such conditions and are dependent on a rough/smooth implant border in 1-piece implants and on the location of the interface (microgap) between the implant and abutment/...

Bridge pier scour is a complex process, which influenced by many parameters, including the presence of ice cover around piers. To better understand influence on bridge scour, an artificial cover, equipped with either smooth or rough surface, was constructed and tested experimentally. The positioned surface water submerged to specified depths in order replicate floating fixed (pressurized) condi...

Hydraulic jump used to dissipate excessive kinetic energy in natural water ways since the down of time. Screens fixed stilling basin control hydraulic location, depth and length from four decades ago. In this study, screens with a constant height different widths same screen relative area (Ar=0.285) were located behind gate at distance 10 cm tested under wide variance conditions submerged jump....

Solid substrate cultures of moulds behave in quite a difTerent way to conventional submerged cultures. Catabolic repression often observed in submerged fermentation can easily be overcome by using solid state fermentation. A. niger strains can be grown by SSF technique with the following advantages: enzyme titres and productivity are usually higher; there is a tendency to early enzyme excretion...

Background: The present in vitro study aimed to investigate the fatigue performance of different dental fixtures two emergence profiles. Biological failures are frequently reported because problem canonly be solved by replacing a failing implant with new one. Clinicians addressed minor mechanical failures, such as bending, loosening or fracture screws, abutment, entire prosthesis, simply fixing...

Marked differences in surface characteristics were observed among three types of single-cell propagules produced by the entomopathogenic fungus Beauveria bassiana. Atomic force microscopy (AFM) revealed the presence of bundles or fascicles in aerial conidia absent from in vitro blastospores and submerged conidia. Contact angle measurements using polar and apolar test liquids placed on cell laye...

Purpose. To investigate peri-implant alveolar bone changes using periapical radiographs before and after prosthetic delivery in submerged and nonsubmerged dental implants. Methods. Digital periapical films of 60 ITI Straumann nonsubmerged dental implants and 60 Xive Dentsply submerged dental implants were taken before, immediately after, and 12 and 24 weeks after the prosthetic restoration was ...

The growth kinetics of Aspergillus nidulans, Mucor hiemalis and Penicillium chrysogenum on solid media and in submerged culture were studied. Growth of A. nidulans colonies on solid medium can be divided into the four phases of lag, exponential, deceleration and constant growth rate. The growth kinetics of A. nidulans in submerged culture were similar to those commonly found for unicellular mic...
