A Simple Biological Treatment for a Slaughterhouse Wastewater: Crimson Publishers

A Simple Biological Treatment for a Slaughterhouse Wastewater by Rafaela Paes de Souza Barbosa, Maria Magdalena Ribas Döll* and Ana Cláudia Barana in Civil Engineering & Technology

Wastewater coming from slaughterhouses by-products contains high amounts of nitrogen, phosphorus, organic matter, salts, and so on. The effluent comes from the water used to wash the animals, scalding, washing the floor and the machines, cleaning of equipment, etc. Before discharging the effluent in the water body, the effluent needs to be treated. To remove the large amount of organic matter and nutrients this study proposed the use of a combined system composed by three biological reactors: anaerobic, aerobic and anoxic. The best removal efficiencies were 90% for COD and 50% for NH4+-N, what decreases large pollutant potential.

Scanning Electron Microscope Configuration of Recycled Carbon Fiber Composites: Mini Review_Crimson Publishers

Scanning Electron Microscope Configuration of Recycled Carbon Fiber Composites: Mini Review by Seyed Hossein Mamanpush in Crimson Publishers : Open Journal of Civil Engineering Carbon fiber composites (CFCs) were mechanically refined and classified the scanning electron microscope (SEM) configuration of untreated and heat-treated mechanically recycled carbon fiber epoxy and carbon fiber vinyl ester composite was examined by using scanning electron microscopy (SEM). SEM Results indicate that the main defects in the structure of recycled CFCs are broken fibers, fiber pull-out, fiber-matrix separation. Also Comparing SEM of untreated and heat-treated recycled CFC indicates that there is no significant difference between their micrographs. https://crimsonpublishers.com/acet/fulltext/ACET.000542.php For more open access journals in   Crimson Publishers   please click on the link   https://crimsonpublishersresearch.com/ For more articles in  Open Journal ...

Tensile Behavior of Single Cast-in Anchors in Plastic Hinge Zones_Crimson Publishers

Tensile Behavior of Single Cast-in Anchors in Plastic Hinge Zones by Jian Zhao in  Crimson Publishers :  Advancements in Civil Engineering & Technology This paper presents two tests of ¾-in. diameter cast-in anchors embedded in the plastic hinge zone of reinforced concrete columns. Design codes, such as ACI 318-11, do not allow concrete anchors in concrete that could be substantially damaged during an earthquake unless special reinforcement is provided. Recent studies have concluded that key role of anchor reinforcement, in addition to carrying the forces from the anchors, is to protect concrete around the anchors from splitting, breaking out, and crushing. The anchor reinforcement in this study was designed according to the recommendation. The column specimens were subjected to quasi-static cyclic loading before the test anchors were loaded in tension. Ductile steel fracture was achieved in both test anchors despite cracks and concrete spalling occurred to the concret...

Creation of Formula to Predict Time and Cost Benefit by Using 5D BIM Rather than Traditional Method of Construction by Arif khan in  Crimson Publishers :  Advancements in Civil Engineering & Technology Building Information Modeling (BIM) is becoming a well-known established collaboration process in the construction industry. Owners are increasingly requiring BIM services from construction managers, architects and engineering firms. Many international construction firms are now investing in “BIM” technologies during bidding, preconstruction, construction and post construction. The goal of this research is to understand and examine the uses and benefits of 5D BIM for construction project of Pakistan. There are three objectives to this research. First is to make comparative analysis of an existing high rise building with reference to scheduling and cost as done by traditional method. Second is to develop 5D model of high rise building with help of autodesk revit and auto...
