The objective of this research was to characterize the ballistic performance p-aramid fabrics impregnated with shear thickening fluid (STF) focusing on laminating sequence layers. A panel all neat Kevlar and two hybrid panels STF were tested against 9 mm bullets at 436 m/s for body armor application. When laminated behind layers (N/S-panel), backface signature decreased compared (N-panel) placed backside (S/N-panel). enhanced N/S-panel assumed be due synchronized (or coupled) elongation...

The objective of this research was to characterize the ballistic performance p-aramid fabrics impregnated with shear thickening fluid (STF) focusing on fabric count and shot location. Panels made different counts were tested against 9 mm bullets at 436 m/s for body armor application. higher dissipated a fraction given impact energy through tensile dissipation led lower backface signature. decrease in signature value by hybridization neat STF smaller panels densely woven due larger difference...

The purpose of this study was to identify risk factors for abscess formation in acute bacterial prostatitis, and compare treatment outcomes between group non-abscess group.This is a multicenter, retrospective cohort study. All patients suspected having an prostatic infection underwent computed tomography or transrectal ultrasonography discriminate abscesses from prostatitis without formation.A total 31 prostate were reviewed among 142 with prostatitis. Univariate analysis revealed that...

The present study was performed to determine the morphologic change and selected molecular features of spontaneous lung tumors in cats examined at North Carolina State University Veterinary Teaching Hospital. Thirty-nine primary carcinomas represented 0.69% all feline cases admitted hospital. Most were observed aged (P < .0001), no sex predilection found .4241). Persian with pulmonary carcinoma overrepresented data set, least 4 times more frequently than other breeds. histologic tumor types...

This study took a retrospective approach to investigate patients with catheter-associated urinary tract infection (CAUTI) over 2 years at single hospital's intensive care unit (ICU) identify meaningful risk factors and causative organisms.A retrograde analysis was performed on indwelling catheters between January 2009 December 2010 in Yeouido St. Mary Hospital medical surgical ICU. CAUTI defined as isolated bacterial growth of 100,000 colony-forming units or more either 48 hours after...

ABSTRACT This study aimed to (i) investigate the antimicrobial susceptibilities of bacteria that cause urinary tract infections (UTIs) in outpatient and inpatient settings (ii) evaluate risk factors for emerging drug resistance UTIs South Korea. In total, 3,023 samples without duplication were collected from females between 25 65 years age who had been diagnosed with a infection. Multicenter patient data using Web-based electronic system then evaluated. The isolation rates Escherichia coli ,...

The aim of this study was to examine the efficacy in ovo prime-boost vaccination against infectious bursal disease virus (IBDV) using a DNA vaccine prime followed by killed-vaccine boost post hatching. In addition, adjuvant effects plasmid-encoded chicken interleukin-2 and interferon-gamma were tested conjunction with vaccine. A plasmid (pcDNA-VP243) encoding VP2, VP4, VP3 proteins very virulent IBDV (vvIBDV) SH/92 strain injected into amniotic sac alone or combination IL-2 (ChIL-2)...
