Tetrapods are vertebrate animals having four feet, legs or leglike appendages. Amphibians, reptiles, dinosaurs/birds, and mammals are all tetrapods, and even the limbless snakes and whales are tetrapods by descent. The earliest tetrapods radiated from the Sarcopterygii, or lobe-finned fish, into air-breathing amphibians. The first tetrapods are now thought to have evolved in shallow and swampy freshwater habitats, towards the end of the Devonian, a little more than 365 million years ago. This documentary walks through our early understanding and discoveries regarding the evolution of tetrapods. The list of known fossils possessing transitional features continues to grow.

Introduction to the Waffle-Crete Structural Precast Building System
Waffle-Crete is a fast and cost-effective structural precast forming system. The Waffle-Crete system uses half the concrete and steel of solid panels of the same thickness, yet provides comparable structural benefits. These significant cost savings along with dramatically faster and easier erection makes it possible to build disaster-resistant housing at a fraction of the cost of traditional precast, pour-in-place and tilt-up systems. Go to www.waffle-crete.com for more information.
This is a video of our roads crew replacing an obsolete metal culvert with a reinforced concrete culvert on Samples Rd in western Pulaski County. The new culvert can also handle about twice the amount of water flow as the old one. In this short clip you can see a trackhoe back-filling sb2 gravel around the already installed concrete pipe. Also there is a worker operating a small roller to compact the new back-filled gravel. The last part of the video shows the trackhoe operator placing large stones along a ditch to reduce erosion and road base scour.
Concrete Form Vibrators from VIBCO www.vibco.com are powerful enough to move even low-slump concrete and greatly reduce casting time and the number and severity of surface imperfections. VIBCO’s clamp on style vibrators are easy to move between forms saving you time and money!
Utranazz recently launched the UK’s most versatile Mobile Volumetric Batching Plant (MVBP). The MVBP has a unique roll-on roll-off system that allows for multiple mounting options: 1. Inside the back of a tipper body 2. Onto a hook-loader sub-chassis 3. Skid-mounted for yard use 4. Permanently mounted onto the back of a lorry The MVBP was designed with the quarrying and recycling markets in mind and is ideal for use by tipper fleet operators and on-site wet batching companies. The unit utilizes an extremely accurate computer-controlled weighing system whereby the cement is weighed via load cells, rather than being based on calculated volumes. The result is the production of very accurate high-quality concrete, which can enable the user to easily achieve QSRMC accreditation.
Condition Assessment of PCCP Pipelines Remote Field Transformer Coupling (RFTC) technology accurately establishes the baseline condition of prestressed concrete cylinder pipe (PCCP). The system detects and quantifies the number of breaks in the prestressing wire that reinforces the concrete pipe. RFTC provides water and wastewater system operators with information on the location, distribution and number of wire breaks anywhere along the length of the pipeline.
