In this paper, using neural networks based on radial basis functions (RBF), a comprehensive closed-form solution for effective length of vertical grounding rod is extracted in such a way that the two effects of ionization and dispersion are simultaneously considered. In creating the model, training data are computed from multi-conductor transmission line (MTL). As a results, firstly in the prop...

Liquefaction hazard induced by seismic events might affect the stability of buried pipelines, with permanent displacements embedded structure as a consequence. In this context, pipe uplift is main concern, already widely discussed in literature. paper, further insights to assess phenomenon and related effects on pipelines are provided based results shaking table tests pipes different apparent u...

Buried charges pose a serious threat to both civilians and military personnel. It is well established that soil properties have large influence on the magnitude variability of loading from explosive blasts in buried conditions. In this study, work has been undertaken improve techniques for processing pressure data discrete measurement apparatus; performed through testing truncation methodologie...

This article reports on the use of comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC×GC-TOFMS) for forensic geotaphonomy application. Gravesoil samples were collected at various depths and analyzed for their volatile organic compound (VOC) profile. A data processing procedure was developed to highlight potential candidate marker molecules related to the decom...

Controlled release urea (CRU) is considered to enhance crop yields while alleviating negative environmental problems caused by the hazardous gas emissions that are associated with high concentrations of ammonium (NH₄⁺) and nitrate (NO₃-) in black soils. Short-term effects of sulfur-coated urea (SCU) and polyurethane-coated urea (PCU), compared with conventional urea, on NO₃- and NH₄⁺ in black s...

Konstantin Dmitrievich Glinka made a major contribution to the development of such areas soil science as genesis, geography, cartography and mineralogy soils. He first world maps (1908, 1915, 1927), map Asian part Russia (1927, jointly with L.I. Prasolov), classic studies weathering processes transformation primary minerals into secondary, buried relic soils, which laid foundation for paleosoil...

The content and composition of lignin phenols in plants soils latitudinal zones vertical natural the North Caucasus Northwest Tien Shan have been studied. special role underground plant organs process humification was revealed. It shown that oxidation degree biopolymer increases during transformation organic matter from living tissues to humic acids soils. fraction fragments remain unchanged bi...
