The processes involved in the major steps of successful revegetation of bauxite residues are examined. The first phase is the natural physical, chemical and microbial ripening of the profile. This involves allowing the profile to drain, dry, shrink and crack to depth, leaching of soluble salts, ...
forests, minerals and water. These resources are unevenly distributed. The Indian continent covers a multitude of biotic and abiotic resource. As India has rapid population growth therefore there is overconsumption of resources, such as uncontrolled logging or overfishing and many valua...
Gypsum and lime-based plasters were used both to assemble the stones of buildings and to produce coatings in ancient Egypt. Concrete was used in construction by the Romans. Over time, building materials have improved, leading to modern concrete with excellent performance, allowing the construction ...
Since these monitoring wells are located in areas with no historic chromium usage, industrial sources of chromium were ruled out. Water testing was performed on twelve monitoring wells in the area that historically had elevated total chromium concentrations ranging from 10-4900 micrograms per litre. ...
Considering the absence of hazard sources connected to human activities, it is reasonable to introduce the hypothesis of natural occurrence of sulphates. Therefore, the delimited research area has been the object of geological, geomorphological and hydrochemical observations to trace the sulphates ...
Such approaches aim to increase the functional efficiency of natural enemy populations by managing habitats in or around crop to offer substitute sources of food, such as prey, pollen, and nectar, as well as providing refuge from agricultural disturbances11,12. More recently, these practices have ...
Ordovician and Silurian deposits are found in the western part of the Eastern European Platform (limestones, argillaceous shales containing graptolites). Kukersite, a type of oil shale, is of Ordovician age. Devonian deposits, including clay-carbonate, gypsum-bearing, and salt-bearing deposits, ...
Other important sources of natural gas are in the form of hydrates sediment present under permafrost regions. The typical composition of natural gas is given in Table 3.8. Table 3.8. Typical Composition Ranges of Fossil Natural Gas ComponentMethaneEthanePropaneButanePentaneHexaneH2H2SO2CO2 Weight ...
The combined use of gypsum and organic amendments can positively impact Na and potassium (K) concentrations, depending on the chemical composition of the amendments, particularly in calcareous saline-sodic soils35. Previous studies have affirmed the effectiveness of organic materials in managing salt-aff...
People are exposed to ionizing radiation from the radionuclides that are present in different types of a natural sources, of which building materials is one of the most important sources. Radionuclides in building materials belonging to 238 U, 232 Th series as well as radioisotope of Potassium 40...
