Ever since the first pulsar was discovered by Bell and Hewish over 40 years ago,we’ve known that not only are pulsars fascinating and truly exotic objects, but that we can usethem as powerful tools for basic physics and astrophysics as well. Taylor and Hulse hammeredthese views home with their discovery and timing of the spectacular “binary pulsar” in the 1970sand 1980s. In the ...

During February 2000, two trout farms, situated in NW Greece, reported unusually high losses of hatchery reared rainbow trout fry and fingerlings. Live fish and chilled samples of diseased whole fish were delivered to a veterinary laboratory in Athens for diagnostic investigation. Infections with the fungus Ichthyophonus hoferi as well as the Gram negative bacterium Aeromonas hydrophila were di...

Corrosion inhibition of SAE 1018 steel by Pseudomonas fragi and Escherichia coli biofilms has been evaluated using batch cultures in rich medium (LB) and seawater-mimicking medium (VNSS) at 23 degrees C and 30 degrees C with or without daily medium replenishment. Biofilm components have been stained simultaneously for polysaccharide (calcofluor) and live and dead cells (Live/Dead Baclit viabili...

In this study, metal matrix composites (MMC) of a CoCrNi medium entropy alloy (MEA) reinforced with titanium nitride (TiN) nano-sized particles were designed for production by laser-based powder bed fusion (LB-PBF). Two different additions, 0.5 wt% and 5 TiN nano- sized particles, mixed using tumbling ball milling, respectively. The results suggest that although the morphology is not significan...

Software companies focusing on Usability Engineering facetwo major challenges, the first being the sheer lack ofusability specialists leading to missing competences in theindustry and the second, which regards small companiessuffering from the constraint of low budgets, thus not beingable to fund usability specialists or comprehensiveconsultancy. Training of non-usab...

In this work, we focus on two basic secure distributed computation tasksProbabilistic WeakSecret Sharing (PWSS) and Probabilistic Verifiable Secret Sharing (PVSS). PVSS allows a dealerto share a secret among several players in a way that would later allow a unique reconstruction ofthe secret with negligible error probability. PWSS is slightly weaker version of PVSS where thedeal...

The amount and sources of carbon and nitrogen used to produce Bacillus thuringiensis (Berliner)-based biopesticide may influence the quality of the final product. The objective of this research was to test different levels of carbon and nitrogen: medium 1 - 1.5% maize glucose + 0.5% soy flour, medium 2 - 3.0% maize glucose + 1.0% soy flour, medium 3 - 1.0% maize glucose + 3.0% soy flour and med...

The purpose of this work is to investigate the ef-fects of pulsed focused ultrasound on the enhancement ofH-Docetaxel delivery in prostate tumors in vivo. Human prostatecancer LNCaP cells (5 x 10) in 24 ml medium were injectedinto the prostates of male nude mice. When tumor reached thesize of 160 ± 10 mm on MRI, HIFU treatment was performedusing an InSightec ExAblate...

After publication it was brought to our attention that the information for one of the variables in Table 1 was incorrect (Weiss, O'Loughlin et al. International Journal of Behavioral Nutrition and Physical Activity 2007, 4:2). The variable in question is "Use of a neighborhood facility for activity". In the first column, the first row should read "yes", and the second row, "no". In the second c...

Differences in expression of the Escherichia coli stress protein HtpG were found following exposure of exponentially growing cells to heat or chemical shock when cells were grown under different environmental conditions. With an htpG::lacZ reporter system, htpG expression increased in cells grown in a complex medium (Luria-Bertani [LB] broth) following a temperature shock at 45 degrees C. In co...
