Evaluation of Soil Re-mineralizer from By-Product of Volcanic Rock Mining: Experimental Proof Using Black Oats and Maize Crops
(Universidad de la Costa, 2019-08-08)
This study was focused on physical, petrographical, mineralogical, and chemical characterization of a volcanic-rock mining by-product (dacite rock), as well as on greenhouse experiment with black oats and maize crops to ...
Comparative assessment of corrosion of concrete reinforced with unprotected steel and hot-dip galvanized steel
(Revista de la Construccion, 2017)
Increasing the lifespan of structures is of great importance for civil construction, either because of economic aspects or security to the users. Corrosion of reinforcement is one of the most recurring problems, especially ...
Chemical evaluation of by-products of the grape industry as potential agricultural fertilizers
(Journal Of Cleaner Production, 2019-06-20)
The grape industry, specifically the wine industry, is generating by-products rich in nutrients, which are underutilized and often end up being polluters of the environment. These byproducts are the bagasse, the stem and ...
Pollution from uncontrolled coal fires: Continuous gaseous emissions and nanoparticles from coal mines
(Journal of Cleaner Production, 2019-01-14)
In this investigation, the coal fires in different Colombian coal mines were studied using advanced
electron beam and X-ray diffraction techniques. The results were compared with information from highresolution transmission ...
Composition And Porosity Study Of Original And Restoration Materials Included In A Coastal Historical Construction
(Construction and Building Materials, 2018-05-22)
The materials used for the building constructions can suffer during their life numerous deterioration processes induced by different anthropogenic and natural factors. For this reason, optimal restoration works are vitally ...
In vitro genotoxic effect of secondary minerals crystallized in rocks from coal mine drainage
(Journal Of Hazardous Materials, 2018-03)
Coal processing generates a large volume of waste that can damage human health and the environment. Often these wastes produce acid drainage in which several minerals are crystallized (evaporites). This study aimed to ...
Copper decreases associative learning and memory in Drosophila melanogaster
(Universidad de la Costa, 2019-11-24)
Copper is an essential element to all living organisms. Repeated use of metal-enriched chemicals, fertilizers, and organic substances may cause contamination at a large scale. Altered levels of Cu2+ may result in harmful ...
Air quality and PM10-associated poly-aromatic hydrocarbons around the railway traffic area: statistical and air mass trajectory approaches
(Universidad de la Costa, 2019)
Diesel engine railway traffic causes atmosphere pollution due to the exhaust emission which may be harmful to the passengers as well as workers. In this study, the air quality and PM 10 concentrations were evaluated around ...
