THE BURDEN OF EMPIRICAL THERAPY: ANALYZING THE PREDOMINANCE OF BROAD-SPECTRUM ANTIBIOTIC USAGE IN LOWER RESPIRATORY TRACT INFECTIONS
Abstract: Lower respiratory tract infections (LRTIs) remain one of the leading causes of morbidity and hospitalization worldwide, particularly among older adults, immunocompromised individuals, and patients with chronic respiratory disorders. These infections include conditions such as community-acquired pneumonia, hospital-acquired pneumonia, bronchitis, and acute infective exacerbations of chronic lung disease, all of which often require rapid clinical intervention. Because microbiological confirmation of the causative pathogen frequently takes 48–72 hours, clinicians generally initiate empirical …

Structure-Property Correlation in PTT/PP Blends with Improved Mechanical Performance
Abstract: The present work investigates a series of poly (trimethylene terephthalate) (PTT)/polypropylene (PP) blends prepared with varying PP concentrations in order to improve the overall performance of PTT, particularly with respect to mechanical properties and processability. PTT is a promising engineering thermoplastic owing to its balanced stiffness, resilience, and chemical resistance; however, its relatively high cost and processing limitations often restrict its wider application. In this context, blending with PP offers …

TiO2-ZrO2 Supported Nickel Oxide Catalysts for Hydrogenation of Levulinic Acid to -Valerolcatone
Abstract: The Titania-Zirconia (TZ) mixed oxide sample (50:50 wt.% percent) was prepared by a simple coprecipitation method and used as a support for the nickel catalyst. The various loadings of nickel content from 1 to 20 wt.% were synthesized for the production of γ-valerolactone (GVL) from levulinic acid (LA). Among all the tested samples, the 5 wt.% Ni/TZ sample exhibited the 98% conversion of LA and 96% selectivity to GVL and …
