The Seven Deadly Sins of Process Analyzer Applications
Abstract On-line process gas analyzers comprise a relatively small proportion of the capital investment in a grass roots project but they require detailed attention if they are to be successfully implemented and fully exploited. The chain is long and the mistakes are many. It runs from front end engineering design, to EPC detailed design, through systems integration, selection of technique and ...

Research on a soft measurement model of sewage treatment based on a case-based reasoning approach
In this paper, the measurement of biochemical oxygen demand (BOD) in a wastewater treatment process is analyzed and an intelligent integrated prediction method based on case-based reasoning (CBR) is proposed in order to overcome difficulties. Due to the fact that there are many factors that influence the accuracy of the prediction model, the radial basis function, which is a neural network ...

Fibroblast growth factor signaling uses multiple mechanisms to inhibit wnt-induced transcription in osteoblasts
Fibroblast growth factor (FGF) and Wnt signals are both critical for proper bone development. We previously reported that the expression of activating FGF receptor mutations in osteoblasts downregulated the expression of many genes reported as targets of Wnt signaling, suggesting an antagonistic effect between Wnt signaling, which promotes osteoblast differentiation and function, and FGF ...

Inertial Labs Introduces the Complete Remote Sensing Payload Solution
Introduction to Remote Sensing and Scanning Light detection and ranging (LiDAR) sensors are a commonly used source of optical information for remote sensing payloads in scanning and surveying applications. LiDAR payloads use penetrating pulses of laser light that are reflected and used to determine the relative distance to the point that it is reflected from. When these pulses backscatter ...

Morphological, bathymetric and sedimentological surveys used to assess the coastline defensive measures
This paper outlines the results of a study recently carried out on the western coast of the Sestri Levante peninsula (Eastern Liguria - Italy), aiming to assess the effects of newly accomplished defensive measures against coastal erosion: the accretion of the beach with natural sand and its protection with artificial structures orthogonal and parallel to the shoreline. Through conventional and ...

Assessment of the removal mechanism of hexavalent chromium from aqueous solutions by olive stone
The objectives of this study were to study the removal mechanism of Cr(VI) by natural olive stone (OS) and to present a sequential-batch process for the removal of total chromium (original Cr(VI) and Cr(III) derived from reduction of Cr(VI) during biosorption at acidic conditions). First, experiments were conducted varying pH from 1 to 4, and showed that a combined effect of biosorption and ...

Estimating the costs of collective treatment of wastewater: the case of Walloon Region (Belgium)
This paper contributes to a better understanding of costs for collective wastewater treatment in the Walloon Region (Belgium). Based on a large set of data, unit costs to population equivalents are modelled. Considering investment as well as exploitation costs, the model includes not only wastewater treatment plants but also collector and sewage networks in an integrated approach at the technical ...

AutoTerrain - Worlds best boom stability
The AutoTerrain works and reacts on both boom movements and twisting forces on the boom. This allows the system to be proactive and react on the cause more than on the symptom. AutoTerrain works with 5 ultrasonic sensors and three gyro sensors. Ultrasonic sensors are located at a given distance on the boom and measure the height of the crops multiple times per second. The gyro sensors measure ...

Research on the infiltration processes of lawn soils of the Babao River in the Qilian Mountain
Using a Guelph Permeameter, the soil water infiltration processes were analyzed in the Babao River of the Qilian Mountain in China. The results showed that the average soil initial infiltration and the steady infiltration rates in the upstream reaches of the Babao River are 1.93 and 0.99 cm/min, whereas those of the middle area are 0.48 cm/min and 0.21 cm/min, respectively. The infiltration ...

A network analysis of transboundary water cooperation in La Plata Basin
When do countries cooperate in transboundary waters? One of the largest in the world, the La Plata Basin covers part of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. These five countries co-manage the basin through a network of legal agreements, domestic and international organizations, and cooperative projects. In this paper, we examine the network structure of cross-national water ...

Adsorption and catalytic oxidation of organic pollutants using Fe-zeolite
In this work, a natural zeolite, modified and loaded with iron (NZ-A-Fe) as a heterogeneous catalyst, was characterized for its suitability as a permeable reactive barrier (PRB) material for treatment of aromatic hydrocarbons in groundwater. Adsorption and oxidation processes were analyzed. Batch adsorption tests for benzene, toluene and xylene (BTX) aqueous concentrated solutions were ...

Online Process Analyzer Installed at F.J. Horgan WTP to Monitor Chloramination
Construction was completed on the City of Toronto's F.J. Hor-gan Water Treatment Plant in 1979, more than 60 years after chloramine had first been used to disinfect drinking water in an Ottawa plant. By then there was little debate about the benefits of chloramination and it was incorporated into the new plant's design as part of the disinfection process. Chloramine is more stable than free ...
