Impact of micro-indentation load/time and Zinc concentration on the thermo-mechanical characteristics of amorphous SeTeSn alloy
We have performed hardness measurement experiments under different loads and
loading times by performing micro-indentation marks in the present work.
Chalcogenide glasses (ChGs) comprising SeTeSn and
SeTeSnZn (where ) alloys are the
subject of micro-indentation tests in this work. We have utilized both
micro-indentation and optical microscopic methods to determine Vickers
hardness. Thermal glass transition phenomena have been identified through DSC
techniques. The modulus of elasticity (E), an essential mechanical property,
has been evaluated using established empirical equations. Further, we have
studied other mechanical parameters [e.g., minimal micro-void formation energy
(Eh), glass's fragility index (m), micro-void volume (Vh), etc.] and the
covalent character of the glassy system. Additionally, various physical
parameters, including density, molar volume, and compactness, have also been
determined

Maxillary Osteomyelitis Caused by Apophysomyces Variabilis - Emerging Trends
In the maxillofacial skeleton, chronic osteomyelitis is more often observed in the mandible than maxilla. Maxillary osteomyelitis is rare because of its rich blood supply. It is usually seen in individuals with impaired immune response, uncontrolled diabetes and hospitalized patients. It can be caused by bacterial, fungal or viral infections. We report a rare case of maxillary osteomyelitis caused by an emerging mucormycete, Apophysomyces variabilis

Impact of an International Nosocomial Infection Control Consortium multidimensional approach on central line-associated bloodstream infection rates in adult intensive care units in eight cities in India
SummaryObjectiveTo evaluate the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control approach on central line-associated bloodstream infection (CLABSI) rates in eight cities of India.MethodsThis was a prospective, before-and-after cohort study of 35650 patients hospitalized in 16 adult intensive care units of 11 hospitals. During the baseline period, outcome surveillance of CLABSI was performed, applying the definitions of the CDC/NHSN (US Centers for Disease Control and Prevention/National Healthcare Safety Network). During the intervention, the INICC approach was implemented, which included a bundle of interventions, education, outcome surveillance, process surveillance, feedback on CLABSI rates and consequences, and performance feedback. Random effects Poisson regression was used for clustering of CLABSI rates across time periods.ResultsDuring the baseline period, 9472 central line (CL)-days and 61 CLABSIs were recorded; during the intervention period, 80898 CL-days and 404 CLABSIs were recorded. The baseline rate was 6.4 CLABSIs per 1000 CL-days, which was reduced to 3.9 CLABSIs per 1000 CL-days in the second year and maintained for 36 months of follow-up, accounting for a 53% CLABSI rate reduction (incidence rate ratio 0.47, 95% confidence interval 0.31–0.70; p=0.0001).ConclusionsImplementing the six components of the INICC approach simultaneously was associated with a significant reduction in the CLABSI rate in India, which remained stable during 36 months of follow-up
