Staphylococcus aureus temperate bacteriophage: carriage and horizontal gene transfer is lineage associated. [PDF]

, 2012
Staphylococcus aureus is a major cause of human and animal infections. Bacteriophage are a class of mobile genetic element (MGE) that carry virulence genes and disseminate them horizontally, including Panton-Valentine leukocidin (PVL), the immune evasion

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Vertical Transmission of Mycoplasma pneumoniae Infection [PDF]

Neonatology, 2018
<i>Mycoplasma pneumoniae</i> is a significant cause of pneumonia in school-aged children and young adults. We report a case of neonatal <i>M. pneumoniae</i> pneumonia in a preterm child manifesting in the first hours of life. Vertical transmission was demonstrated by the detection of <i>M.

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

First report of venereal and vertical transmission of canine leishmaniosis from naturally infected dogs in Germany

Parasites & Vectors, 2012
Background Canine leishmaniosis (CanL) is a zoonotic disease caused by Leishmania (L.) infantum. It is endemic to several tropical and subtropical countries but also to the Mediterranean region.

The Atmospheric Chemistry of GJ 1214b: Photochemistry and Clouds [PDF]

, 2011
Recent observations of the transiting super-Earth GJ 1214b reveal that its atmosphere may be hydrogen-rich or water-rich in nature, with clouds or hazes potentially affecting its transmission spectrum in the optical and very-near-IR.

Thermophysical Properties of the Desulphurization Slags With Various CaS and CaO/Al2O3 Ratio

Advanced Engineering Materials, EarlyView.
This article investigates how CaS content and the CaO/Al2O3 ratio influence the thermophysical properties of desulphurization slags. Using experimental measurements and thermodynamic simulations, this study reveals complex effects on viscosity, surface tension, and density, providing new insight into slag structure and phase behavior under ...
