Sources of Contaminants of Emerging Concern in Groundwater of Barcelona Urban Area

Groundwater is a vital resource for the development of urban areas, where the problem focuses on the quantity and on the quality of this freshwater resource. Barcelona is a good example as because currently groundwater is used for irrigatio...

Compilation of Apatite Fission-Track Data from the Northeast Atlantic Realm: A Jigsaw Puzzle with Missing Pieces

The northeast (NE) Atlantic is one of the best-studied geological regions in the world, incorporating a wide array of geological phenomena including extensional tectonism, passive margin development, orogenesis, and breakup-related volcanis...

Mineralogy, geochemistry and fluid inclusion studies of Dagh-Dali Zn-Pb(±Au) Deposit, Northern Takab, Northwest Iran

Dagh-Dali Zn-Pb deposit is located 40 km north of Takab city and it consist of Bekhair-Bolaghi and Baldirghani ore zones. Mineralization in Bekhair-Bolaghi is consist of galena, sphalerite, pyrite and chalcopyrite with disseminated texture ...

Deglacial release of petrogenic and permafrost carbon from the Canadian Arctic impacting the carbon cycle

Abstract The changes in atmospheric pCO2 provide evidence for the release of large amounts of ancient carbon during the last deglaciation. However, the sources and mechanisms that contributed to this process remain unresolved. Here, we pres...

Morphological Changes of the Lower Ping and Chao Phraya Rivers, North and Central Thailand: Flood and Coastal Equilibrium Analyses

The Chao Phraya River flows in the largest river basin of Thailand and represents one of the important agricultural and industrial areas in Southeast Asia. The Ping River is one major upstream branch flowing down slope southwardly, joining ...

Assessing the impact of forest structure disturbances on the arboreal movement and energetics of orangutans—An agent-based modeling approach

Agent-based models have been developed and widely employed to assess the impact of disturbances or conservation management on animal habitat use, population development, and viability. However, the direct impacts of canopy disturbance on th...

Mathematical and Physical Papers

William Thomson, first Baron Kelvin (1824–1907), is best known for devising the Kelvin scale of absolute temperature and for his work on the first and second laws of thermodynamics, though throughout his 53-year career as a mathematical phy...

Datasets associated with investigating the potential for beneficial reuse of produced water from oil and gas extraction outside of the energy sector

The data in this report are associated with https://doi.org/10.1016/j.scitotenv.2020.137085 [4] and include data on water volumes and water quality related to the major unconventional oil and gas plays in the U.S. The data include volumes o...

Effects of environmentally relevant ibuprofen and valproic acid exposure on zebrafish behavior

Active pharmaceutical ingredients (APIs) are increasingly entering aquatic environments due to human and veterinary use, wastewater discharges, and inadequate waste containment, raising significant concerns for both ecosystems and human hea...

Geography and International Relations

The world we live in happens to be a diversified, highly partitioned space. The surface of the earth is partitioned in a great many ways: politically and physically, economically and culturally. The political divisions are the raison d'être...

Tracking Hydrological Regime Shifts Through the Anthropocene: The Samara River, Southern Cis-Urals

The Samara River is a left-bank tributary of the Volga with a total basin area of 46,500 km2, of which 22,800 km2 is the gauged area analyzed in this study. This river system serves as a case study for examining hydrological transformations...

Subduction, collision and plumes in the epoch of the Late Paleozoic magmatism of the Magnitogorsk zone (the Southern Urals)

Subject. A systematization of Late-Paleozoic magmatic formations of the Magnitogorsk zone of the Southern Urals in the process of an accretion of the Magnitogorsk paleoarc to the margin of the East European continent (EEC) with formation in...

Selective green removal of arsenic from wet-process phosphoric acid using marine-derived Neptune ball Fibres

Abstract Phosphoric acid is the second most widely produced mineral acid worldwide and is predominantly manufactured via the wet process. However, wet-process phosphoric acid (WPPA) contains significant levels of dissolved and suspended imp...

Advances and perspectives for receiver function imaging of the Earth's internal discontinuities and velocity structures

Studying the structures, properties and origins of the Earth's internal discontinuities is an important part in the efforts to understand the physical and chemical properties of the layered Earth, as well as to explore the dynamic processes...

Effect of the Double-Line Spiral Tunnel Curvature on the Tunnel Construction Stability

In the construction of mountain highway, in order to avoid complicated geology and adapt to the requirements of the terrain of the large height difference and the large slope, the double-line spiral tunnels are gradually applied. The purpos...

Multithreaded two-pass connected components labelling and particle analysis in ImageJ

Sequential region labelling, also known as connected components labelling, is a standard image segmentation problem that joins contiguous foreground pixels into blobs. Despite its long development history and widespread use across diverse d...

Classification and hydrocarbon distribution of passive continental margin basins

Sixty-six passive continental margin basins around the world were compared comprehensively from the aspect of seismogeology on the basis of plate tectonics. According to their textural and structural differences, passive continental margin ...
