The enterotoxigenic and porcine enteropathogenic Escherichia coli (EtEc and PEPEc) strains are agents associated with swine neonatal diarrhea, causing economic losses in swine production. The main goal of this study was to identify virulence genes of EtEc, verotoxigenic (VtEc) and PEPEc in intestinal strains responsible for swine diseases, by molecular typing using Pcr in newborn piglets from a...

We present and discuss the ionospheric F-region observations from equator to equatorial ionization anomaly (EIA) regions over South American sector during an intense space weather event occurred between 27 May 29, 2017. During this geomagnetic storm, symmetric-H (SYM-H) reached a minimum of −142 nT at ∼0700 UT on 28, For investigation, we analyze vertical total electron content (VTEC) chain nea...

With the rapid development of global navigation satellite systems (GNSS) and their increasingly wide range applications in atmospheric science, total electron content (TEC) data are widely used theoretical study layer coupling related to seismicity. This detected analyzed pre-earthquake ionospheric anomalies (PEIA) by using TEC from Royal Observatory Belgium (ROB), coseismic disturbance (CID) w...

Space weather describes varying conditions between the Sun and Earth that can degrade Global Navigation Satellite Systems (GNSS) operations. Thus, these effects should be precisely timely corrected for accurate reliable GNSS applications. That modeled with Vertical Total Electron Content (VTEC) in Earth’s ionosphere. This study investigates different learning algorithms to approximate nonlinear...

There is a long standing and widely held view that the many sub-forms of the haemolytic uraemic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) share a common final pathogenetic pathway. This was expressed recently in a review article in this journal [1]. This is an assumption which deserves to be challenged. It appears to be based on the concept that the histological hallmark of t...

Abstract Ionosphere Associate Analysis Centers (IAACs) of the International GNSS Service (IGS) independently produce global ionosphere maps (GIMs) total electron content (TEC). The GIMs are based on different modeling techniques, resulting in TEC levels and accuracies. In this study, we evaluated accuracy consistency IAAC during high (2014) low (2018) solar activity periods 24th cycle. our appl...
