INFLUENCES OF THE LOGGERHEAD SPONGE (SPHECIOSPONGIA VESPARIUM) AND THE VASE SPONGE (IRCINIA CAMPANA) ON NEARSHORE HARDBOTTOM COMMUNITY DEVELOPMENT IN THE FLORIDA KEYS Scott Donahue Old Dominion University, 2008 Director: Dr. Mark J. Butler IV Sponges, octocorals, and stony corals are the dominant sessile fauna within shallow, hard-bottom communities in the Florida Keys, FL (USA). The sponge com...

Abstract Local scouring around the piers of a bridge is one major reasons for failure, potentially resulting in heavy losses terms both economy and human life. Prediction accurate depth local difficult task due to many factors that contribute this process, however. The main aim study thus offer new formula prediction pier using modern fine computing modelling technique known as gene expression ...

most previous laboratory studies of local scour at bridge abutments were performed in rectangular channels in which the distributions of flow velocity and bed shear stress were considered uniform in the transverse direction. in reality however, bridge abutments are usually located in the floodplain zone of rivers where velocity and shear stress distributions are directly affected by the lat...

A. M. K. Bahrum Prang Rocky Abstract-This study attempted to evaluate the eco-friendly bio-scouring and the conventional chemical (mainly NaOH) scouring processes of cotton & comparison between the effectiveness of both types of scouring process on cotton fibres and fabrics in the Textile industries. Less developed countries, like Bangladesh, do not set strict rules and regulations to discharge...

BACKGROUND Removal of non-cellulosic impurities from cotton fabric, known as scouring, by conventional alkaline treatment causes environmental problems and reduces physical strength of fabrics. In this study, an endo-polygalacturonase (EndoPG) from Aspergillus aculeatus produced in Pichia pastoris was evaluated for its efficiency as a bioscouring agent while most current bioscouring process has...

Abstract. Water flowing in the river causes a scouring event that occurs at bed channel. The existence of will increase along with changes geometry and obstacles such as weir which are followed by local around weir. Local often downstream end sill weakens its construction. Scouring measurement was conducted to monitor pattern occurs. By using Surfer software, visualization through Data Grid 3D ...
