This project focuses on the protection and management of Edinburgh’s Old and New Towns, renowned for their historical and architectural significance. Despite global pressures from tourism and commercial development, Edinburgh has established a robust world cultural heritage protection and management system. The approach integrates top-down and bottom-up strategies, involving dedicated municipal officials and an independent organization, the Edinburgh World Heritage Trust. The city’s emphasis on ...

Sedimentary environments are an important part of paleogeography and sedimentology, and there is a long history of using geochemical and mineralogical methods to analyze palaeoenvironmental problems using sedimentary rocks as a research vehicle. By summarizing the important results of previous work on tracing the palaeoenvironment using the composition and distribution characteristics of the macronutrients and trace elements as well as the characteristics of mineral composition, we aim to sort o...

At present, the Brillouin Optical Time Domain Reflectometer (BOTDR) sensor has been widely used in oil and gas pipeline monitoring and maintenance, and the ability to resist cross-interference is weak for the BOTDR sensor system, and it cannot process interference data at the same time. A Polarized Optical Time Domain Reflectometer (POTDR) based on the polarization effect is designed, which is based on the traditional POTDR sensor system and combined with the fiber grating, by using the fiber gr...

Oil mining wastes such as Produced water, drilling muds and cuttings may lead to contamination of groundwater. The study investigated whether Produced water from the oil well pads in south Lokichar basin, Turkana County, Kenya, leads to contamination of the neighboring groundwater resources. The specific objectives of the study were to 1) determine the physicochemical properties of Produced water and 2) determine the physicochemical properties of boreholes water near oil well pads. Produced wate...

The spatial local anomalies of the concentration ratios for isotopes 143Nd/ 144Nd (or εNd) and 87Sr/ 86S in Lukkulaisvaara intrusion (North Karelia) were discovered. The physical mechanisms and the descriptions of the effect of an arising of those anomalies were developed and presented. The base of the proposed mechanisms is the phenomena of the migration (diffusion) of components, due to the (T, P (or D)) gradients. The description of the processes of a...

This study
was to determine the seasonal variations of groundwater, the influence of the rock
formations on the groundwater solute chemistry and groundwater domestic-agro-industrial
quality using hydrogeochemical tools and physicochemical parameters; Ionic
ratios, Gibbs diagrams, Piper diagrams, Durov diagrams and water quality
indices. From
physicochemical parameters; in the rainy season, pH ranged from, 4.6-7.1 ...

Clouse to faults or unstable areas where an earthquake could happen with capacity of affecting
buildings or infrastructure, there is often a previous energy that wanders around surroundings,
this energy regularly is associated to electromagnetic emissions that generate an electric
potential frequently studied as very, ultra-low and extreme frequency emissions (VLF-ULFELF_
EM) by remote sensing; under the assumption that this natural potential exist, in aquatic
environment within the micro-seismi...

This current paper
discusses an application of the aerial radiometric method in the Itaboraí Region,
located in Rio de Janeiro State, Brazil. Radiometric data acquired by aircraft
registered in counts per second of potassium, thorium and uranium channels were
processed generating radiometric maps of the entire region. The generated maps
provide important information regarding the superficial geology. At last, all
the radiometric information gained is correlated with geological and
topographical ...
