Surface Water Geochemistry and Chemical Weathering Across Panama
Abstract A geochemical study of rivers and streams was undertaken across Panama during 2005-09, from the Lago Bayano area in the east to the Costa Rican border in the west. Low overall dissolved solute contents (TDS = 145±160mg/L) suggest a short...

Groundwater Salinization in a Coastal Multilayer Aquifer: Preliminary Results on Origins and Mechanisms- Example of Recife (Brazil)
Abstract The Recife Metropolitan Region (PE, Brazil) appears as a typical environmental “hot spot” illustrating the problems of southern countries, such as urbanization or rapid industrial and touristic development. All of these factors induce high...

Dielectric properties of coals in the low-terahertz frequency region
Abstract The dielectric properties of Shanxi anthracite and Shandong bituminous coals in China are investigated in the low-terahertz (THz), W-band of frequency from 75GHz to 110GHz for the first time. In this frequency range, the complex dielectric...

Suitability assessment of artificial neural network to approximate surface subsidence due to rock mass drainage
Abstract Based on the previous studies conducted by the authors, a new approach was proposed, namely the tools of artificial intelligence. One of neural networks is a multilayer perceptron network (MLP), which has already found applications in many...

A p-version embedded model for simulation of concrete temperature fields with cooling pipes
Abstract Pipe cooling is an effective method of mass concrete temperature control, but its accurate and convenient numerical simulation is still a cumbersome problem. An improved embedded model, considering the water temperature variation along the...

A system dynamics computer model to assess the effects of developing an alternate water source on the water supply systems management
Abstract The purpose of developing alternate water sources is to secure water sources of sufficient quantity and high quality due to water quality and/or quantity problems of an existing water source and, thereby, raise the level of consumer...

3D Simulation of Ship Motions to Support the Planning of Rescue Operations on Damaged Ships
Abstract The paper describes a software system to simulate the ship motions in a crisis situation. The scenario consists of a damaged ship subjected to wave excitation forces generated by a random sea state. The simulation is displayed in an...

Quantifying Geomorphic Controls on Time in Weathering Systems
Abstract The time minerals spend in the weathering zone is crucial in determining soil biogeochemical cycles, solid state chemistry and soil texture. This length of time is closely related to erosion rates and can be modulated by sediment transport, ...

Effective management of heat transfer fluid flash point temperatures using a light-ends removal kit (LERK)
Abstract Heat transfer fluids (HTF) need to be regularly sampled to assess the extent of thermal degradation, oxidative state, the accumulation of short-chained light-ends and contamination by intrinsic or extrinsic particles. The build-up of...
