This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...

A delay in diagnosing hollow viscus injury (HVI) causes an increase in mortality and morbidity. HVI remains a challenge to diagnose, and there is no specific diagnostic biomarker for HVI. We evaluated the utility of intestinal fatty acid-binding protein (I-FABP) in diagnosing HVI in blunt trauma patients. Within a 5-year period, 93 consecutive patients with clinically suspected HVI at our traum...

Purpose To analyze the intra-urban differentials related to the outcome of the Newborn Hearing Screening (NHS) of children living in Belo Horizonte tested in a reference service using the Health Vulnerability Index (HVI). Methods cross-sectional study with children living in Belo Horizonte evaluated by a Newborn Hearing Screening Reference Service (NHSRS) between 2010 and 2011. The HVI of the...

This study examined the adequacy of a health vulnerability index (HVI) for identifying intra-urban differences in vulnerability in the elderly population. Study participants (n = 1,055) were selected by probabilistic sampling of residents in the city of Belo Horizonte, Minas Gerais State, Brazil, aged 60 years or older (mean = 70.1 years). The HVI was constructed with indicators of socioeconomi...

The purpose of this study is to understand how countries have leveraged on their economic resilience fight the COVID-19 pandemic. focus a global sample 150 countries. develops health vulnerability index (HVI) and leverages an existing (ERI) provide four main scenarios from which problem statement, namely ‘low HVI-low ERI,’ ‘high HVI-high ERI’ quadrants. Countries that robustly fought pandemic a...

Hypervelocity impact (HVI), ubiquitous in low Earth orbit with an impacting velocity in excess of 1 km/s, poses an immense threat to the safety of orbiting spacecraft. Upon penetration of the outer shielding layer of a typical two-layer shielding system, the shattered projectile, together with the jetted materials of the outer shielding material, subsequently impinge the inner shielding layer, ...

BACKGROUND AND AIMS Viral hepatitis is a serious complication among intravenous drug users (IDUs). The objectives of this study were to determine the seroprevalence of hepatitis B and C viruses (HBV and HCV), and associated risk factors among IDUs at a teaching hospital in Ahvaz, southwest Iran. METHODS Medical records of 333 IDUs hospitalized from 2002 to 2006 at Razi Hospital, which is affi...

Ten cotton varieties/hybrids with varying properties, such as 2.5% span length measured by HVI, AFIS & Baer Sorter; bundle strength at 3.2mm measured by HVI and Stellometer; and linear density measured by AFIS, HVI and Gravimetric method, have been studied. Maturities are also compared between AFIS and caustic soda methods. In addition, short fibre content measured by HVI, Baer Sorter and AFIS ...

In the classic horizontal vertical illusion (HVI), vertical lines appear 5-6% longer than horizontal lines. However, in outdoor scenes vertical poles of several meters appear as much as 25% longer than frontal ground extents. This large-scale HVI is consistent with angular scale expansion theory (Durgin & Li, 2011). It is known that the classic HVI is yoked to the reference frame of the eye its...

We sequenced the entire ∼16 kb canine mitochondrial genome (mtGenome) of 100 unrelated domestic dogs (Canis lupus familiaris) and compared these to 246 published sequences to assess hypervariable region I (HVI) haplotype frequencies. We then used all available sequences to identify informative single nucleotide polymorphisms (SNPs) outside of the control region for use in further resolving mtDN...
