This study presents an application of artificial neural network (ANN) and Bayesian (BN) for evaluation jamming risk the shielded tunnel boring machines (TBMs) in adverse ground conditions such as squeezing grounds. The analysis is based on database tunneling cases by numerical modeling to evaluate convergence possibility machine entrapment. results initial were verified comparison with some case studies. A dataset was established performing additional various scenarios variation most...

ABSTRACT Several actinomycetes isolated from nature were able to use both natural rubber (NR) and synthetic cis -1,4-polyisoprene (IR) as a sole source of carbon. According their degradation behavior, they divided into two groups. Representatives the first group grew only in direct contact substrate led considerable disintegration material during cultivation. The second consisted weaker decomposers that did not grow adhesively, indicated by formation clear zones (translucent halos) around...

The practical value of elaborated vibrational spectroscopic techniques in medical and microbiological biodiagnostics depends strongly on the reliability, speed, ease use, evaluation procedures acquired data. In present study, artificial neural networks (ANNs) were used to establish a hierarchical classification system for microbial Fourier transform infrared (FT-IR) spectra suitable identification purposes routine laboratory. A radial basis function network (RBF) proved be superior top-level...

ABSTRACT Differentiation of the species within genus Listeria is important for food industry but only a few reliable methods are available so far. While number studies have used Fourier transform infrared (FTIR) spectroscopy to identify bacteria, extraction complex pattern information from spectra remains difficult. Here, we apply artificial neural network technology (ANN), which an advanced multivariate data-processing method analysis, at level. A hierarchical classification system based on...

Severe shield jamming events have been reported during excavation of Uluabat tunnel through adverse geological conditions, which resulted in several stoppages at advancing a single shielded boring machine (TBM). To study the mechanism, three-dimensional (3D) simulation and surrounding ground was implemented using finite difference code FLAC3D. Numerical analyses were performed for three sections along with higher risk entrapment due to combination overburden conditions. The computational...

A novel sulphate-reducing bacterium (Al1T) was recovered from a soured oil well in Purdu Bay, Alaska. Light and atomic force microscopy observations revealed that cells were Gram-negative, vibrio-shaped motile by means of single polar flagellum. The carbon energy sources used the isolate salinity, temperature pH ranges facilitating its growth proved to be typical partial lactate-oxidizing, moderately halophilic, mesophilic, bacterium.

A classification system based on Fourier transform infrared (FTIR) spectroscopy combined with artificial neural network analysis was designed to differentiate 12 serovars of Listeria monocytogenes using a reference database 106 well-defined strains. External validation performed test set another 166 L. The O antigens (serogroup) 164 strains (98.8%) could be identified correctly, and H were correctly determined in 152 (91.6%) the Importantly, 40 out 41 potentially epidemic serovar 4b...

Studies were initiated to determine whether the formation of lipid-linked oligosaccharides was coupled synthesis protein. Canine kidney cells grown with [2-3H]mannose or [3H]leucine in presence cycloheximide puromycin and effect these inhibitors on proteins measured. In all cases, inhibition protein resulted a substantial incorporation mannose into oligosaccharides, although mannosyl-phosphoryl-dolichol only slightly inhibited. Cycloheximide had no vitro when GDP-[14C]mannose incubated aorta...

Abstract Characterization and identification of fungi in food industry is an important issue both for routine analysis trouble‐shooting incidences. Present microbial techniques fungal characterization suffer from a low throughput are time consuming. In this study we present protocol high‐throughput microcultivation spectral by Fourier transform infrared spectroscopy. For the 11 species total five different genera ( Alternaria , Aspergillus Mucor Paecilomyces Phoma ) were analyzed FTIR All...

Biofouling is a problem in many different industrial fields, causing damage of product or interfering with production processes, ranging from drinking and purified water systems to paper manufacture, heat exchange cosmetics, pharmaceutical, medical electronic device industries. Timely countermeasures, optimization efficacy control depend on monitoring biofilm growth surfaces. As samples give no information about site extent biofilms, surface sampling mandatory. The development should be...

We describe a new Fourier transform infrared (FT-IR) spectroscopy-based diagnostic approach, which may provide for the first time rapid, reliable, and inexpensive blood test scrapie related transmissible spongiform encephalopathies (TSE). Blood serum from 146 terminally ill Syrian hamsters infected with 263K via different routes of inoculation 166 healthy control animals was analyzed by FT-IR spectroscopy artificial neural networks (ANN). This revealed characteristic molecular alterations in...

Since 1986, more than 180 000 clinical cases of bovine spongiform encephalopathy (BSE) have been observed in the U.K. alone. Most these were confirmed by postmortem examination brain tissue. However, BSE-related risk assessment and management would greatly benefit from antemortem testing on living animals. A serum-based test could allow for screening cattle population; thus, even a BSE eradication program be conceivable. Here we report novel method testing, which combines infrared...

Abstract Der vorliegende Beitrag beleuchtet die Marktdurchdringung von Drohnen im Bauwesen DACH‐Raum sowie mit dem Drohneneinsatz auf Baustellen verbundenen Herausforderungen. Einsatz zur Baufortschrittskontrolle hat in den letzten Jahren durch moderne Erfassungsmethoden wie Fotogrammetrie und LiDAR erheblich zugenommen. Diese Technologien verbessern Datenpräzision Datenerfassung, bringen jedoch auch technische, rechtliche finanzielle Fragestellungen sich. Eine Studie 423...

The main component of biofilms is water, which can make up to over 90% the wet weight. Biofilms are therefore considered as hydrogels.
