We have studied the genetic basis of beta-lactamase production in eight strains of Haemophilus ducreyi isolated in diverse areas of the world. Beta-lactamase production in all strains was mediated by plasmids having a molecular mass of either 5.7 or 7.0 megadaltons. Plasmids of 5.7 megadaltons were shown to carry the entire sequence of pFA7, the beta-lactamase specifying plasmid found in isolat...

When transacting and interacting through open computer networks, traditional methods used in the physical world for establishing trust can no longer be used. Creating virtual network substitutes with which people, organisations and software agents can derive trust in other parties requires computerised analysis of the underlying trust networks. This article describes an approach to trust networ...

The efficiency, reliability, and safety of aircraft have been improved by substituting hydraulic mechanical systems with electric systems. Furthermore, in future aircraft, where fan-driving engines are partially replaced motors, solving the thermal management heat generation from motor-controlling power-devices will become a crucial problem. In this study, three-dimensional steady network analy...

Abstract In this study, the ENSO teleconnection with tropical North Atlantic (TNA) sea surface temperatures (SSTs) in boreal spring is analyzed ocean–atmosphere coupled global circulation models. To assess role played by horizontal resolution of models on teleconnection, we used a multimodel dataset that first to combine both low and high resolution. The TNA response projects onto most signific...

The season-dependent impacts of the tropical North Atlantic (TNA) sea surface temperature anomaly (SSTA) on subsequent El Niño-Southern Oscillation (ENSO) evolution were investigated through observational and modeling studies. results indicate that, although maximum amplitude TNA SSTA occurs during boreal spring, in summer generates a stronger rainfall response situ, which can further induce si...

BACKGROUND The translation and cultural adaptation of widely accepted, psychometrically tested tools is regarded as an essential component of effective human resource management in the primary care arena. The Training Needs Assessment (TNA) is a widely used, valid instrument, designed to measure professional development needs of health care professionals, especially in primary health care. This...

Transnational access (TNA) allows cross-border, short-term and frequently free-of-charge to world-class research facilities, foster collaborations exchanges of experience. Specifically, TNA aims encourage open science innovation increase the efficient effective use scientific infrastructure. Within EPOS, European Plate Observing System, Volcano Observatories Multi-scale Laboratories communities...

The main objective of this study was to utilize high field (7T) in vivo proton magnetic resonance imaging to increase the ability to detect metabolite changes in people with ALS, specifically, to quantify levels of glutamine and glutamine separately. The second objective of this study was to correlate metabolic markers with clinical outcomes of disease progression. 13 ALS participants and 12 ag...
