Seasonal and spatial variations in metal concentrations and pH were found in a stream at a restored copper mine site located near a massive sulfide deposit in the Foothill copper-zinc belt of the Sierra Nevada, California. At the mouth of the stream, copper concentrations increased and pH decreased with increased streamflow after the onset of winter rain and, unexpectedly, reached extreme value...

Oil sands mining in the boreal forest produces large volumes of liquid tailings. Forestry research has generally focused on thickness and composition soil layers to be placed top tailings during reclamation. However, release water, which may seep into root zone affect plants. Furthermore, interactions combined effects hypoxia substrate chemistry plant responses are poorly understood. The aqueou...

This article discusses about qanan which is a way to cook food that typical for the Tehit tribe. Cooking patterns using bark are not done every day, but only carried out on special rituals, example, traditional, religious, and government events. The cooking begins with preparation of meat, mixed green spices vegetables. ingredients have been seasoned arranged in has dialed into inside then tied...

Although the deep sea is the largest ecosystem on Earth, its infaunal ecology remains poorly understood because of the logistical challenges. Here we report the morphology of relatively large burrows obtained by in situ burrow casting at a hydrocarbon-seep site and a non-seep site at water depths of 1173 and 1455 m, respectively. Deep and complex burrows are abundant at both sites, indicating t...

Authigenic carbonate build-ups develop at seafloor methane-seeps, where microbially mediated sulphate-dependent anaerobic oxidation of methane facilitates carbonate precipitation. Despite being valuable recorders of past methane seepage events, their role as archives of atmospheric processes has not been examined. Here we show that cyclic sedimentation pulses related to the Indian monsoon in co...

In this paper, we introduce and study an inertial algorithm for approximating solutions of split equality fixed point problem (SEFPP), involving quasi-phi-nonexpansive mappings in uniformly smooth 2-uniformly convex real Banach spaces establish a strong convergence theorem. We give applications our result to (SEP), variational inclusion (SEVIP) equilibrium (SEEP). Our results extend, generalize...

Material fluxes associated with fluid expulsion at cold seeps and their contribution to oceanographic budgets have not been accurately constrained. Here we present evidence that the barium released at cold seeps along the San Clemente Fault zone may significantly impact the geochemical budget of barium within the basin. Barium fluxes at seep localities on the fault scarp, measured with benthic ...
