The state of Oklahoma has experienced an unprecedented increase in earthquake activity since 2009, likely driven by large-scale wastewater injection operations. Statewide injection rates peaked in early 2015 and steadily decreased thereafter, approximately coinciding with collapsing oil prices and regulatory action. If seismic activity is primarily driven by fluid injection, a noticeable seismo...

We review the "critical point" concept for large earthquakes and enlarge it in the framework of so-called "finite-time singularities." The singular behavior associated with accelerated seismic release is shown to result from a positive feedback of the seismic activity on its release rate. The most important mechanisms for such positive feedback are presented. We solve analytically a simple mode...

Robert Anthony Department of Earth and Environmental Science, New Mexico Institute of Mining and Technology Abstract Since the early 1960s when Maruyama and Burridge and Knopoff convincingly demonstrated that the elastodynamic radiation patterns exhibited by shear faulting in an isotropic, elastic medium were consistent with a pair of force couples, it has become standard practice amongst seism...

Coral reef ecosystems of the South Pacific are extremely vulnerable to plastic pollution from oceanic gyres and land-based sources. To describe the extent and impact of plastic pollution, the distribution of both macro- (>5 mm) and microplastic (plastic < 5 mm) of the fringing reef of an isolated South Pacific island, Mo'orea, French Polynesia was quantified. Macroplastic was found on every bea...

Possibilities of creation circular business models in agriculture for system gathering, recycling and processing a plastic waste packing firm mineral fertilizers are analyzed. The resource model connected with replacement materials design reservoirs (big-bags) the purpose their use economy at organization technologies is offered.

Environmental problems caused by plastic pollution in terrestrial systems have received increasing attention, especially the issues related to micro- and nanoplastics. Soils are a major receptacle reservoir of plastics, accumulated plastics can negatively affect soil health. In this short review, we discuss current state knowledge subsurface transport nanoplastics soils. We fundamental mechanis...

In this review, a historical perspective, functional and application trends of natural polymers used to the development edible food packaging were presented discussed. Polysaccharides proteins, i.e., alginate; carrageenan; chitosan; starch; pea protein, considered. These are important materials obtained from renewable plant, algae animal sources, as well agroindustrial residues. Historically, s...

Plastic pollution is one of the most significant environmental issues worldwide During Covid-19 pandemic, single-use plastic containers have been overused due to a lock-down policy This led remarkable increase in municipal wastes An alternative method manipulate recycle them as construction and building materials The research introduces an idea using straw produce fibre-reinforced polymer compo...
