Abstract: A wave generating apparatus and method is provided in which a controller actuates a plurality of wave generating chambers in sequence using a delay between actuation of each chamber to produce a rideable wave in a pool. The actuation delay period may be a predetermined proportion of the chamber period. The amount of delay in the sequence can determine the direction that the peak of the wave travels and the amplitude of the peak. Through the sequencing, the peak of the wave produced can travel in a direction not substantially perpendicular to the wave generating chambers.

Abstract: A berm to increase capacity of an existing landfill comprises fill material and a covering portion.

The fill material has a base, an inner sloped surface adjacent a future accumulation of waste, and an outer sloped surface opposite the inner sloped surface. The fill material comprises contaminated fill material fully encapsulated by an impermeable membrane. The covering portion comprises structural fill material and at least partially covers the fill material. At least a portion of the berm sits on at least a portion of the edge surface of the landfill, and portions of the berm are substantially parallel to corresponding portions of the outer perimeter.

Abstract: A shield support assembly for underground mining includes a shield canopy and at least one floor runner as supporting surface elements. The shield canopy and at least one runner are connected in an articulated manner and can be pressed against rock at least one hydraulic cylinder which is supported in bearing pans on the shield canopy and floor runner. Each surface supporting element includes a welded construction of welded-together components.

Abstract: The present invention relates generally to a method of soil remediation or bioremediation 10 generally comprising the steps of: 1. 12, treating contaminated soil with a chemical surfactant in a primary treatment stage; 2. 14, further treating the soil with an aliphatic or aromatic hydrocarbon; 3. 20, implementing final soil remediation processes where necessary until remediation criteria is achieved. The contaminated soil includes organic contaminants including, among other things, polycyclic aromatic hydrocarbons (PAH).

Abstract: A drainage system for draining a fluid is disclosed. The drainage system includes a drain basin having a tubular body, the tubular body including a lumen, an outer surface, a top end, and a bottom end. The drainage system also includes at least one pipe connected to the tubular body and an end cap coupled to the bottom end of the tubular body, the end cap including a convex surface configured to divert the fluid to the at least one pipe, wherein the convex surface of the end cap is inserted through the bottom end and is disposed within the lumen of the tubular body.

Abstract: The invention relates to a method of building a harbor structure suitable for communicating with a stretch of water. The invention is characterized in that the method consists in making, in a piece of ground, at least one curved continuous wall having a closed outline, in digging out the volume defined by the continuous wall, and in providing at least one opening in the continuous wall, said opening making it possible to cause said volume to communicate with the stretch of water.

Abstract: A connection arrangement for subsea connection of at least a first fluid conduit to a second fluid conduit. A supporting unit displaceably supports the connection arrangement against a supporting surface. A coupling device couples and secures the fluid conduits to the connection arrangement thereby interconnecting the fluid conduits to each other. A frame carries the coupling device and is slideably and/or pivotably mounted to the supporting unit so as to allow the frame and the associated coupling device to slide and/or pivot in relation to the supporting unit.
