Ebook "Renewal of potable water pipes: Pipeline infrastructure committee" provides a detailed resource on planning, design, and construction of trenchless rehabilitation technologies for pipelines carrying drinking water. Trenchless renewal, rather than open-cut pipe replacement, offers a variety of benefits, including lower risk of damage to surrounding area, fewer traffic disruptions, better public safety, and shorter completion times.

In this study, the simultaneous determination of Co, Cd, Ni, Cu, and Pb was carried out as a color complex with 4-(2-pyridylazo) resorcinol in an aqueous solution under the assesting of machine learning. A partial least-squares multivariate linear regression and artificial neuron network for the analysis of mixtures of metals were developed. MATLAB is a powerful software machine learning program that was used to support matrix calculations and displays.

Biodegradable “green” and safe substitutes to minimize environmental and health risks are drawing extensive attention for research interest. This research aims to create a water-soluble cationic starch-grafted biodegradable polymer that can be used as a flocculant. As polymers are strong molecules that carry charges, they are effective flocculants. Saturated polymer chains do not change the pH value on adding to wastewater.

The research on the structure of the phytoplankton community in relation to the physicalchemical parameters of seawater needs to be carried out to see indicators of fertility and availability of natural food in the waters that will be used as a marine aquaculture location. To find out the relationship between physico-chemical parameters and phytoplankton abundance, Principal Component Analysis (PCA) was used. Some physico-chemical parameters observed were temperature, brightness, pH, salinity, coated oxygen (DO), phosphate, nitrate, and ammonia.

Ebook "Visualization of hydrogen-bond dynamics: Water-based model systems on a Cu(110) surface" have been carried out by means of spectroscopic methods where the signal stems from the ensemble of a system and the hydrogen-bond dynamics were inferred indirectly. This book addresses the direct imaging of hydrogen-bond dynamics within water-based model systems assembled on a metal surface, using a scanning tunneling microscope (STM).

The pontoon-separate floating bridges have many advantages to apply to the construction of civil floating bridges in Vietnam. This article presents the study of the influence of beam stiffness on the force transmission of concentrated load to the pontoon and the bending moment in the beam caused by this load, as a basis for designing civil poonton bridge to carry loads for small tonnage motor vehicles serving rural traffic.

In ebook "Catalysis with supported size-selected Pt clusters: Fundamental UHV and applied ambient experiments" Florian Schweinberger investigates the influence of the precise size of catalytically active species on reactivity. In order to do this he carries out studies both in UHV and under ambient conditions for supported, size-selected Platium clusters (8-68 atoms). Schweinberger probed the electronic structure, adsorption properties and reactivity of two olefins on surfaces and Pt clusters in the submonolayer range.

A comparative assessment of chemical and functional properties of some varieties of lima bean consumed in Arondizuogu, Imo state were carried out. Methodology: Seven varieties of lima bean, identified on the basis of colour were purchased from a local market. One kilogram of each variety was cleaned, washed with tap water and milled into fine flours (70mm mesh screen).

Gobies are dominant in terms of both species diversity and abundance in estuarine habitats, but little is known about their early developmental stages in the coastal waters of Vietnam. To examine species diversity of goby larvae and juveniles, monthly collections were carried out using a small seine net from the Ka Long estuary in the northernmost Vietnamese coast, from September 2014 to August 2015.

The primary goal of this research is accomplishing the BUUAS that can realize functions in the mission profile. In order to achieve this, the project starts with developing elemental aspects of the BUUAS. The configuration and propulsion system are two basic elements that the BUUAS must have to realize successfully operation. Besides, the necessary transition process between water and air must be investigated and carried by a conceived system.

Dry bean (phaseolus vulgaris L.) field experiment was carried out under the subhumid climatic conditions of Bafra, Turkey, to evaluate the possibilities of using hyperspectral reflectance data for estimating yield and water consumption. Three irrigation management treatments that depend on monitoring soil water content and one rain-fed treatment were subjected to dry beans arranged in a randomized complete block design with three replications.
