The rotary-percussion drilling method is a prospective way to decrease costs. It obvious, based on literature analyses and finished geothermal drilling, that the Lublin Basin can be perceived as one where used drill an overburden of shale rocks. paper explained geology Basin, its’ geological structures, possibility use with down-the-hole hammer, which could significantly cost whole gas investme...

Recent sediment accumulation rates in Adventfjorden (Svalbard), a small subpolar fjord, were determined by Pb and Cs dating. Modern rates in the central basin decrease downfjord from 1.87 to 0.87 cm y−1 (2.6 to 1.19 g cm−2 y−1). Comparison of the modern values (1986–2001) with older ones (1963–86) reveals a marked increase in sediment accumulation rates in the last ten years. This correlates we...

Hydrocarbon generation in the Zechstein Main Dolomite and Upper Triassic potential source rocks of Polish Basin was investigated by 1-D thermal maturity modelling 90 boreholes across basin. This identified major zones potentially worthy further exploration efforts. The maximum burial depth reached >5 km during Late Cretaceous leading to organic matter. development reveals considerable differ...

The debate on abortion gets heated because some people feel that abortion should be abolished while others argue that is should be legalized. Those who against abortion reason that life begins at conception, and hence the unborn child has equal human rights with any other living person. This makes them state that abortion is murder and that those involved should be charged with murder in a cour...

In this paper, the problem of recovery of morphological information lost in abbreviated forms is addressed with a focus on highly inflected languages. Evidence is presented that the correct inflected form of an expanded abbreviation can in many cases be deduced solely from morphosyntactic tags of the context. The prediction model is a deep bidirectional LSTM network with tag embedding. The netw...

The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos Islands, and its spring-fed ecosystems have very low nutrient content (nitrogen or phosphorous) and are dominated by diverse microbialites. Thus, it has proven to be a distinctive opportunity for the field of astrobiology, as th...

Advanced oxidation processes (AOPs) have led the way in the treatment of aqueous waste and are rapidly becoming the chosen technology for many applications. In this paper, COD reduction potential of leather tanning industry wastewaters by Electro-Fenton (EF) oxidation, as one of the AOPs, was experimentally evaluated. The wastewater sample was taken from an outlet of an equalization basin in a ...

The Boolean formula value problem is in alternating log time and, more generally, parenthesis context-free languages are in alternating log time. The evaluation of reverse Polish notation Boolean formulas is also in alternating log time. These results are optimal since the Boolean formula value problem is complete for alternating log time under deterministic log time reductions. Consequently, i...

The reverse Polish notation properties are used in the construction of the algorithms for the polygon triangulation. The formal grammar method is “translated” to the arithmetic expression field enabling application of the reverse Polish notation method. The result of this approach is a relatively simple algorithm for polygon triangulation.

background and objectives: pulse oximetry is the most common technique for monitoring hemoglobin oxygen saturation (spo2). different colors and brands of nail polish may cause disturbance in the reading and interpretation of oxygen saturation. the aim of this study was to determine the effect of different colors of nail polish on oxygen saturation measured by pulse oximeter. methods: thirty hea...
