Quaternary geology and paleoseismology in the Fucino and L’Aquila basins

Quaternary geology and paleoseismology in the Fucino and L’Aquila basins

To the east, in the background, are the Quaternary continental terraces uplifted along the Cerchio-Pescina fault. The «upper terraces» include two main terrace surfaces of Late Pliocene (?) - Early Pleistocene age. The highest one culminates at 1050 m a.s.l. and represents the top of the most ancient lacustrine cycle, as demonstrated also by wave-cut terraces in the bedrock. The second one is faulted and reworked by a depositional surface of the Alto di Cacchia unit culminating at 950 m a.s.l. (Fig. 11). Two intersecting NW-SE and SE-NW trending normal faults border the «upper terraces» and generate fault scarps up to 100 m high. In the middle, the Fucino Lake was filling the wide basin until the year 1870. Except for the artificial drainage of the lake in Roman times first and eventually by Alessandro Torlonia, the Fucino basin was hydrologically closed (endorheic) throughout the whole Quaternary.

Quaternary Adder Design on FPGA

Quaternary Adder Design on FPGA

In quaternary adder which is made up of radix 4 system, the operations performed are carry free addition and borrow free subtraction. The addition performed here is carry free addition so the speed of operation is very fast in comparison with standard adders [1]. In this paper standard CMOS design is used to design adder. Clock boosting technique is used to optimize the switches resistance and power consumption. In CMOS technology the full adder prototype based on LUT works at 100 MHz and it consumes power of 122 µW [2]. The result shows efficiency of the proposed design. In quaternary adder the number of input bits are independent, the final result we get has the constant delay this delay is not depend on number of input bits i.e. when the input is of 4 bit, 8 bit,16 bit ,32 bit and more, the delay is same. So for the higher number of bits and complex circuit the delay is independent. The current mode circuit allow successful improvement in terms of area. In the voltage mode look up table the major problem is power dissipation and it uses standard CMOS process, the threshold voltage is different for different transistors hence more number of fabrication steps are required and this is very expensive.

Reduced water supplies coupled with increasing demand are putting a strain on global water supplies. Global warming further threatens water supplies by increased evaporation of surface water, increased occurrence and severity of floods. UNESCO recognized this crisis by issuing Millennial Development Goal Number 7, Target 10, which gives governments the mandate to reduce by half the percentage of the population without access to safe drinking water. In Kenya, water shortages amount to a humanitarian crisis. Turkana County, in northwest Kenya, is the driest county in the country, and its residents are some of the poorest. UNESCO’s GRIDMAP division, in conjunction with the Government of Kenya and funded by the Government of Japan, in 2013 commissioned Radar Technologies International to complete a comprehensive, high tech survey of groundwater resources in this county. This survey utilized the latest technique in combining remote sensing data with existing data on hydrology and geology to create models of potential for groundwater occurrence. The models were then tested by collecting field data and field samples to verify the conclusions and developed into maps of groundwater occurrence.

Engineering Geology Abstracts

Detailed examinations of engineering geology are required for Elon Musk’s proposed high speed train from Washington, D.C. to New York City. Five maps of bedrock geology as well as coastal and surficial geology were created using GIS. These maps provide spatial relationships between engineering geology and topography along the proposed tunnel axis. From bedrock geology maps basaltic rocks located ~5 miles southwest of New York City are the hardest unit of rock to drill through while chiefly red shale, situated ~15 miles southwest of New York City is the most drillable bedrock. Furthermore, Lowland terrace deposits have a very poor foundation condition bearing capacity of 1 ton/ft 2 and relatively high coefficient of permeability (300-1000 gal/day/ft 2 ),

Arithmetical Operations in Quaternary System

Arithmetical Operations in Quaternary System

Abstract—The digital circuits became more prominent with incorporating information processing and computing. The modern computers lead to the deterioration in performance of arithmetic operations such as addition, subtraction, multiplication, division, on the aspects of carry propagation delay, large circuit complexity and high power consumption. Arithmetic circuits play a very critical role in both general-purpose and application specific computational circuits. Designing this adder using QSD number representation allows fast addition/subtraction which is capable of carry free addition and borrows free subtraction because the carry propagation chain are eliminated, hence it reduce the propagation time in comparison with radix 2 system. QSD number system based on quaternary system, each digit can be represented by a number from -3 to -3.

A Quaternary ZnCdSeTe Nanotip Photodetector

A Quaternary ZnCdSeTe Nanotip Photodetector

ZnSe is an important II–VI semiconductor with wide direct bandgap energy of 2.67 eV and large exciton binding energy of 21 meV at room temperature. Two-dimensional (2-D) ZnSe-based epitaxial layers can also be grown directly on the closely lattice matched GaAs substrate. Other than the binary ZnSe, it is possible to grow strained and/or lattice matched ternary/quaternary epitaxial layers so as to achieve ZnSe-based heterostructures. Using these heterostructures, ZnSe-based light emitting diodes [1], laser diodes [2], and photodetectors [3] have all been demonstrated. Other than 2-D epitaxial films, one-dimen- sional (1-D) semiconductor nanostructures such as nano- wires, nanorods, nanotips, and nanotubes have attracted great attention in recent years. With a significantly larger surface-to-volume ratio, 1-D semiconductor nanostructures exhibit unique optical and electronic properties that make them desirable for use in various novel devices. For example, it has been shown that 1-D ZnO nanowire pho- todetector exhibit extremely high photoconductive gain [4]. Very recently, we also reported the fabrication of a 1-D ZnSe nanowire photodetector [5].

Introduction to the Quaternary of northern England

Introduction to the Quaternary of northern England

Northern England is a large geographical area, stretching from the Cheshire–Shropshire low- lands in the south to the Scottish Borders in the north. As such it contains a wide variety of dis- tinctive landscapes and much scenic diversity. This varied topography reflects the interplay of geological controls, geomorphological process- es and the effects of climatic change, most recently during the Quaternary Period. The present landscape, therefore, is the result of a long history of evolution that reflects the inter- action of geology, topography, climate, geomor- phological processes, and their changes through time. The effects of climatic changes are record- ed both in landforms and sediments, and in the records of flora and fauna and their change over time. Evidence for environmental change dur- ing the Quaternary Period, therefore, is wide- spread and diverse in its nature. It is clear that we need to understand the nature of these envi- ronmental changes if we are to have any success in predicting future changes in climate. It fol- lows that the sites containing the most impor- tant evidence for Quaternary climatic change must be preserved for future research and study.

Quaternary stratigraphy and palaeogeography of Poland

Quaternary stratigraphy and palaeogeography of Poland

Though the stratigraphical and palaeogeographical framework of the Quaternary in Poland is still to be completed, several crucial points have been confirmed recently. The preglacial series, accepted for years as belonging to the Lower Pleistocene, is undoubtedly of Early Pliocene age, with a huge hiatus above almost until the uppermost Lower Pleistocene. The earliest glaciation in Poland (Nidanian) occurred at about 900 ka BP when the ice sheet reached the mid-southern part of the country. The following Podlasian Interglacial embraced the Brunhes/Matuyama boundary in the middle, in a similar fashion to the corresponding Cromerian Complex in Western Europe. The late Early and early Middle Pleistocene interglacials in Poland comprised 2-3 optima each, whereas every one of the younger interglacials was characterised by a single optimum only. The Late Vistulian ice sheet was most extensive in the western part of Poland (Leszno Phase) whereas the younger Poznań Phase was more extensive in the central and eastern part of the country. This was due to the varied distance from the glaciation center in Scandinavia, making the ice sheet margin reach a terminal position in different times. Palaeo- climatological research in the Tatra Mountains has provided new evidence for the atmospheric circulation over Europe. During cold phases of the Pleistocene in Poland a continental climate extended further westwards, quite the opposite that occurring during warmer intervals.

Earthquake Geology of Myanmar

Earthquake Geology of Myanmar

Strike-slip faults within the thin tail of the Indoburman range conform to the dextral-reverse nature of the Coco-Delta domain. Breaking the low topography of its eastern portion are several linear features that strike roughly parallel to the range front and to the nearby plate margin (Fig. 3a and Fig. 3c). One outlying block, partially surrounded by sediments of the Ayeyarwady River appears to have shifted right-laterally about ten km from the main body of the range along the Seindaung fault. Unfortunately, the resolution of the SRTM imagery is too coarse to tell whether or not the faults laterally offset small channels and ridges there, so we do not venture an opinion as to whether or not these faults are currently active. Their sharp geomorphic expression does, however, suggest that they have been active within the Quaternary Period. Farther north, where the Indoburman range widens and transitions to the next domain, drainages are larger and more developed. Some of these display right-lateral offsets of about 10 km. We discuss these further in the next section.

A Geology of the General Intellect

A Geology of the General Intellect

“mediation,” there are post-Kantian implications for thinking a “transcendental geology” laid out rigorously by thinkers such as Gilles Deleuze, Iain Hamilton Grant, Ben Woodard and Benjamin Bratton. While Grant’s transcendental geology favors Schelling’s geophysicalist process of universal ungrounding over Deleuze’s onto- realist process of universal ungrounding, he sutures it to a kind of philosophical realism that makes one question if the earth even exists or is merely a mystical “nature-subject” or “specimen of debate”¾losing the earth in a fabricated philosophical hyperspace in the process. Ben Woodard’s transcendental geology quickly becomes “geeky” and “indulgent,” making the earth a hyper-porous sci-fi domain of “swiss-cheese” for extra-terrestrial worms. Bratton’s transcendental geology is interesting, though, because it implies that capitalism’s empirical operations of exploitation, innovation and accumulation already engage in a hyper-speculative transcendental geology via “The Stack” (i.e. a global megastructure made possible by planetary computation). With Bratton, the earth is the layer that provides the material, energy and geological inputs needed to meet the demands of computing but also structures the horizon of cognition’s powers or potential. The earth could even become “obsolete” if capitalist technicity learns to harness energy from “stars”¾literalizing what Gaston Bachelard calls the “anthropocosmic tissue,” a relation of the human to the cosmos that only had an imaginative, theological or poetic role prior.
