Submarine pipelines are a safe and energy-efficient mode of gas transport. However, due to the complex manufacturing process and harsh operating environment, submarine pipelines are subject to fatigue cracks under long-term cyclic loading. A comprehensiv...

Multiples can cause artifacts in imaging; however, they contain information about underground structures. If the internal multiples are removed as a noise, the information contained by the internal multiple will also be removed. This will cause loss of s...

One of the most effective techniques to obtain PP and PS images is elastic reverse time migration which employs multi-component seismic data. The two types of complementary images play an important role in reducing blind spots in seismic exploration. How...

The ?Hispanic Paradox? suggests that despite rates of poverty similar to African Americans, Hispanics have far better health and mortality outcomes, more comparable to non-Hispanic White Americans. Three prominent possible explanations for the Hispanic P...

Precise surveys are indispensable in coastal engineering projects. The extensive presence of sand in the coastal area leads to significant attenuation of seismic waves within unsaturated loose sediments. As a result, it becomes challenging for seismic wa...

Given the amplitude of migration in Europe and its potential to encourage or hinder the agricultural development, the general objective of this paper is to assess this possible potential on the long term, within a sustainable development frame of referen...

Vector decomposition of P- and S-wave modes from elastic seismic wavefields is a key step in elastic reverse-time migration (ERTM) to effectively improve the multi-wave imaging accuracy. Most previously developed methods based on the apparent velocities ...

Africa is a net importer of food, especially cereal grains, despite the importance of agriculture in the continent. The agricultural growth in Africa has been undermined by low investment in agriculture, poor infrastructure, high population growth rate, ...

Cretaceous porphyry copper deposits of northern Chile (28º-29º30? S) are genetically related with dacitic to dioritic porphyries and they represent a still poorly-explored target for Cu resources. The porphyries correspond to stocks distributed into two ...

The HYDRUS-1D and HYDRUS (2D/3D) computer software packages are widely used finite element models for simulating the one-, and two- or three-dimensional movement of water, heat, and multiple solutes in variably-saturated media, respectively. While the st...

Methods of observing birds in flight now include training them to fly under known conditions in wind tunnels, and fitting free-flying birds with data loggers, that are either retrieved or read remotely via satellite links. The performance that comes to l...

ABSTRACT. The Potrerillos district displays major facies boundaries, records changes in the compositions of magmas from Jurassic to Oligocene time, and provides evidence that a porphyry copper deposit and associated skarn (37 Ma) formed between Jurassic-...
