The generation of tailings in the world today is immense, since only ounces or pounds metals are extracted for each ton ore processed. In 2022, it was estimated that more than 14 billion metric tons mining were produced per year world. Currently, many environmental problems associated with management both Chile and Peru related to potential contamination soil, water, air. this article, impacts caused by storage facility accidents where spills have occurred analyzed, describing...

The spatial temporal dynamic behavior supernatant process water pond is studied as critical issue, using remote sensing techniques based multispectral satellite imagery. To understand current state art, brief description engineering studies for control in...

Peru is one of the most diverse countries in world, and its climatic characteristics, biodiversity, cultural heritage, location on planet give it a vast potential for wind energy, both coast within 200 miles which comprise Peruvian coastline Pacific Ocean. Likewise, northern central areas country represent regions with greatest energy use. In this context, viable alternative to mitigate effects climate change local territories and, thus, meet Sustainable Development Goals (SDGs) outlined...

In this study, the quality of sediment and surface water in two natural wetlands, Paca Tragadero, central region Peru was evaluated using pollution indices, including geoaccumulation index, pollutant load modified degree, potential ecological risk site rank for four heavy metals. Principal component analysis used to identify metal contaminant sources. The determination Fe, Zn, Pb, As performed by flame atomic absorption spectrophotometry. average concentrations metals sediments both lagoons...

The afforestation of grasslands can alter different ecosystems’ functional processes; it affects the water balance due to high demand, caused by increased productivity plantations, increase evapotranspiration, and reduces base flow basins. In Uruguay, there are two scenarios; headwaters Tacuarembó River, where area plantations has for more than 30 years, Río Negro, mainly preserved without significant changes. This article evaluates dynamics grassland in basins, through spatial temporal...

Many university students have doubts about how or where to start writing their undergraduate thesis work; it is common not be clear identify a research problem even towards which topic oriented, and there are process systematize so much information available in the era of digitalization. This article presents learning strategies formulate for engineering programs, with an emphasis on use communication technologies (ICTs) toward University Education 4.0 paradigm. The main themes issues...

Urbanization in large cities has altered the urban thermal balance, creating heat islands. In this context, green areas are crucial regulating climate. This study uses remote sensing data to evaluate their performance using fractional vegetation cover (FVC) and its impact on land surface temperature (LST) Metropolitan Lima, Peru, between 1986 2024. The spatial temporal relationship FVC LST is analyzed, districts classified based effectiveness regulation. Mann–Kendall test was applied...

Abstract Objectives The aim of the study was to compare antibacterial efficacy mixtures based on Theobroma cacao (ThC), ThC plus erythritol, and + erythritol Psidium guajava (PsG) Streptococcus mutans Candida albicans in vitro. Materials Methods Pure extract used through desiccation alcohol, guava leaves were macerated 96% alcohol. Tests conducted four groups: pure ThC, sweetened with PsG, chlorhexidine as a control strains S. C. albicans, at concentrations 100, 75, 50, 25%, respectively,...

Objetivo. Este estudio examina la influencia del posicionamiento de rocas basálticas Grupo Serra Geral en Rio Grande do Sul, Brasil, sobre las firmas espectrales, analizadas con espectroscopia reflectancia.

Para cada orientación se...

The high-Andean vegetation ecosystems of the Bombón Plateau in Peru face increasing degradation due to aggressive anthropogenic land use and climate change scenario. lack historical evolution information makes implementing adaptive monitoring plans these vulnerable difficult. Remote sensor technology emerges as a fundamental resource fill this gap. objective article was analyze over almost four decades (1985–2022), using high spatiotemporal resolution data from Landsat 5, 7, 8 sensors....

Abandoned mining–metallurgical sites can significantly impact the environment and human health by accumulating heavy metals in aquatic ecosystems. The water sub-basin near an abandoned smelting facility city of La Oroya, Peru, is primarily used for pisciculture. objective this study was to assess risk from exposure via dietary intake rainbow trout (Oncorhynchus mykiss) influence area a located central Andean region Peru. bioconcentration factor, biosediment accumulation consumption risks...

Surface sediment quality of potential rivers in Peru was evaluated using indicators contamination, accumulation and ecological risk heavy metals As.Surface samples were collected at 54 sampling sites the Tishgo Chia during 2018.The determination Cu, Pb, Zn As performed by flame atomic absorption spectrophotometry.The results revealed decreasing order mean concentrations River > Cu Pb Cu.The PLI for greater than one (PLI 1) denoting deterioration it has been experiencing.In River, 60%...

The aboveground net primary productivity ( ANPP) of bofedales is one the most important indicators for provision ecosystem services in high Andean areas. In case bofedales, evaluation ANPP supply capacity as a service on spatial and temporal scale through remote sensing has been little addressed. capacity, intra interannual, to provide wetlands was quantified at level sensing. normalized difference vegetation index NDVI) MODIS sensor used according Monteith model (1972), product incident...

El trabajo concluye reconociendo percepciones similares y observando nexos entre «la ciudad» «el campo», la priorización de SEH, relevancia los factores responsables cambio necesidad urgente una visión sistémica, holística, interdisciplinaria con inclusión actores, para el fomento del desarrollo sostenible

Cultural heritage provides a wide range of economic, socio-cultural and environmental benefits for current future generations. Globally, scientific evidence shows that climate change is adversely affecting diverse tangible intangible cultural [1; 2]. Yet, in the Netherlands, there need greater understanding vulnerability to hazards. Understanding hazards paramount importance inform guide proactive adaptation planning reduce potential damage or loss [3; 4; 5]. The aim this study evaluate...

Abstract Under the influence of concentrated and extended urbanization, Andean cities different altitudinal zones their “hinterlands” are experiencing profound changes in land cover — from central plazas up to highest peaks. The complex regional-geographic characteristics these socioecological systems, such as vertical complementarity use, require a montological perspective on verticality urbanization: it transcends disciplinary approaches can be crucial properly interpret trajectories...
