Enhanced environmental disinfection is linked to reduced hospital-acquired infection rates. In this study, we aimed to evaluate the efficacy of an emerging disinfection technology, a filtered far-UV-C handheld (FFUHH) device, for reducing bacterial loads on high-touch surfaces in shared clinical workrooms, and to isolate, identify and characterize clinically significant environmental pathogens.
Methods:
We compared samples from high-touch items (dictation device, mouse, armchair, desk, and keyboard) before and after FFUHH treatment. Samples were collected weekly: contact plates for colony counts and swabs before and after intervention on standardized adjacent areas for each surface, respectively. The swabs were enriched and cultured on selective media to isolate pathogens. Environmental samples, as well as clinical samples collected from patients during the study period, were validated using MALDI-TOF and whole genome sequencing.
Results:
Among the 440 collected plates (220 before and 220 after treatment), the highest mean colony count pre-treatment was detected from armchairs, and the lowest from keyboards. The mean reduction of colony-forming units ranged 53% and 83% and was statistically significant (P < 0.05) across all surfaces except for the keyboard. We characterized multidrug-resistant Staphylococcus epidermidis ST5 and ST16 strains, a carbapenem-resistant Acinetobacter baumannii, and a Klebsiella pneumoniae genetically related to a clinical isolate with a rare sequence type not previously detected in our institution.
Conclusion:
The FFUHH effectively reduced the microbial burden on high-touch surfaces. It can offer an advantage for surface disinfection and an alternative to routinely used biocides.
Channel coding lies at the heart of digital communication and data storage. Fully updated, including a new chapter on polar codes, this detailed introduction describes the core theory of channel coding, decoding algorithms, implementation details, and performance analyses. This new edition includes over 50 new end-of-chapter problems and new figures and worked examples throughout. The authors emphasize the practical approach and present clear information on modern channel codes, including turbo and low-density parity-check (LDPC) codes, detailed coverage of BCH codes, Reed-Solomon codes, convolutional codes, finite geometry codes, product codes as well as polar codes for error correction and detection, providing a one-stop resource for classical and modern coding techniques. Assuming no prior knowledge in the field of channel coding, the opening chapters begin with basic theory to introduce newcomers to the subject. Later chapters then extend to advanced topics such as code ensemble performance analyses and algebraic code design.
‘Print stone’ is an iron-banded siltstone from the Pilbara Province of Western Australia that bears partial resemblance to iconic East Kimberley ‘zebra rock’ in both pattern morphology and mineralogical composition. Using a combination of mineralogy and elemental geochemistry, this investigation examines the mechanisms underlying the formation of periodic iron-oxide banding in print stone. We demonstrate that print stone patterns probably arose from the periodic deposition of hydrothermal pyrite during the early Palaeoproterozoic, as evidenced by the distinctive cuboid morphology of the hematite pigment, the deposition of iron oxides along fluid-transport pathways, the presence of extensive hydrothermal pyrite elsewhere in the formation, and the presence of a positive europium anomaly. Through spatial analysis of the iron-oxide banding, we further show that print stone adheres to the Liesegang spacing law with a spacing coefficient of 0.018. This suggests that the periodic deposition of pyrite in print stone arose due to the Liesegang phenomenon, which was probably triggered by the infiltration of near-neutral, sulfidic hydrothermal fluids into a ferruginous, feldspathic shale. Altogether, the present findings demonstrate the opportunity for iron-oxide Liesegang bands to develop in hydrothermal systems, providing additional insight into the mechanisms underlying the formation of the East Kimberley zebra rock and other banded geological material.
