The gold mineralization in the southern region of Tra Nu-Phuoc Thanh was initially discovered and assessed by the Central Geological Division. However, mineralization characteristics and ore-controlling factors in the Tra Nu-Phuoc Thanh area remain inadequately understood. This study conducts a comprehensive synthesis of prior research findings, complemented by the analysis of an additional 50 thin sections, 100 thick sections, SEM scanning electron microscopy, and 10 ICP-MS samples.

This study aims to investigate the characteristics of the salinization phenomenon in water systems and its controlling factors based on hydrogeochemical analysis, seawater-freshwater mixing model and End Members Mixing Analysis. The results revealed that seawater intrusion negatively affects strongly on surface water quality with different magnitudes, depending on seasonal variation and tidal regime.

Ebook "Vegetation-Climate interaction: How plants make the global environment (Second edition)" offers a readable and accessible account of the way in which the world's plant life partly controls its own environment. Starting from the broad patterns in vegetation which have classically been seen as a passive response to climate, the authors build up from the local scale - with microclimates produced by plants - to the regional and global scale.

Varto and the surrounding region have important geothermal fields, developing in strike-slip tectonic setting in East Anatolia, which resulted from the collision of the Arabian and Eurasian plates. The main structural elements in the area are the NE-trending sinistral and NW-trending dextral strike-slip fault segments and N-S trending extension zones. In order to determine fault-controlled geothermal circulation, it is very important to fully characterize the structural elements in these complex environments.

This study uses 2D seismic lines located in the central Song Hong Basin, covering an area of c. 3900 m2, in the water depth of c. 100 m. Focused fluid flows are developed intensively and can be classified into two types: blow - out pipe and seepage pipe.

The present investigation intends to examinations the morphometric attributes of Ozat River basin to comprehend the hydrogeological behavior and influence on hydrology of the basin. The basic and derived morphometric parameters (linear, areal and relief aspects of drainage network) for the basin were determined using ASTER DEM (30 m resolution),remotely sensed images of Linear Imaging Self Scanner III (LISS III) and Geographic Information System (GIS).

Nearly one million weekly listeners trust NPR's Brooke Gladstone to guide them through the distortions and complexities of the modern media. This brilliant radio personality now bursts onto the page as an illustrated character in vivid comics drawn by acclaimed artist Josh Neufeld. The cartoon of Brooke conducts the reader through two millennia of history-from the newspapers in Caesar's Rome to the penny press of the American Revolution and the manipulations of contemporary journalism.

The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of humankind.[26] The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000 BC;[27] scholarly consensus indicates that Homo erectus had controlled fire by between 500,000 BC and 400,000 BC.

Sometimes a burst of diversification is accompanied by dramatic morphologi - cal evolution—an event known as an adaptive radiation. When the ancestors of Darwin’s finches arrived on the Galápagos Islands a few million years ago, they did not simply evolve into 14 barely distinguishable species. They evolved dis- tinctive beaks and behaviors that allowed them to feed on cactuses, crack hard nuts, and even drink the blood of other birds. The Great Lakes of East Africa also saw an adaptive radiation of cichlid fishes.

In many small and shallow aquifers the hydrochemistry does not evolve further. However, the baseline natural quality of groundwater may vary spatially within the same aquifer if the mineral assemblages vary, and also evolves with time as the water moves along groundwater flow lines. If an aquifer dips below a confining layer (Figure 2.5), a sequence of hydrochemical processes occurs with progressive distance down gradient away from the outcrop, including precipitation of some solids when relevant ion concentrations reach saturation levels for a solid mineral phase.

Technology is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function. It can also refer to the collection of such tools, machinery, modifications, arrangements and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments.

Generally, technicism is a reliance or confidence in technology as a benefactor of society. Taken to extreme, technicism is the belief that humanity will ultimately be able to control the entirety of existence using technology. In other words, human beings will someday be able to master all problems and possibly even control the future using technology. Some, such as Stephen V. Monsma,[43] connect these ideas to the abdication of religion as a higher moral authority.
