Coagulation-flocculation is the most important parts of water treatment process. Traditionally, optimum pre coagulant dosage is determined by used jar tests in laboratory. However; jar tests are time-consuming, expensive, and less adaptive to changes in raw water quality in real time. Soft computing can be used to overcome these limitations. In this paper, multi-objective evolutionary Pareto op...

Studies were conducted in large arenas and simulated kitchens to compare the effectiveness of eight traps (seven sticky traps and one jar trap) and Þve attractants formonitoringGerman cockroaches (Blattella germanica L.). The evaluated traps were Trapper (type 9110Ð1), Catchmaster 150, 1001, and 2881, Victor-M330, Victor-M327, Glue board in D-Sect station, and a baby food jar trap. In choice te...

The present contribution is directed towards the concept of a reliable SHM system for grouted joints of the offshore wind turbines. It focuses on static and dynamic tests of a laboratory structure with a grouted joint, on a proper finite element modelling of its behaviour and damage progress. The entire structure as well as the joint itself is subjected to static and dynamic tests. The material...

The goal of this study was to investigate the performance coagulation-flocculation, and sedimentation tests reduce contaminant concentrations in domestic wastewater ecologically acceptable levels. were performed at (ONEE) laboratory using a jar test apparatus (GPB FLCDidatec, France) for enhancing primary treatment effluent from plant Ain Aouda City, Rabat, Morocco. Aluminum sulphate Al 2 (SO 4...

Three commercially available anaerobic cabinets are described and their performance in relation to one another and to a standard anaerobic jar technique are reported upon from a clinical laboratory.

The bioefficacy of a commercial formulation of temephos, Creek against Aedes aegypti larvae was studied in the laboratory. Earthen jars were filled with 10 L tap water each. One g of temephos (Creek) sand granule formulation was added into each earthen jar as recommended by the manufacturer. The final test concentration of Creek was 1 mg a.i./L. One earthen jar was filled with 10 L tap water an...

the aim of this study was to evaluate sound and decayed wood of iranianbeech (fagus orientalis) with a nondestructive stress wave method. wood samples,with dimensions of 9 by 19 by 200 mm were decayed in laboratory soil-bed tests,based on european pre-standard env-807. the decay was evaluated by measuringbending dynamic modulus of elasticity (moed) and longitudinal dynamicmodulus of elasticity ...

background and aims: since the epidemiological, clinical and experimental characteristics of meningitis are different for various locations, this study was conducted to investigate the characteristics of meningitis patients admitted to hospitals of yazd in the 2009 to 2013. materials and methods: in this cross-sectional and descriptive study, all 261 patients with meningitis were considered in ...
