Health Utility Assessment Using EQ-5D among Caregivers of Children with Autism
submitted by ogradivca 1 hour ago - Topic: Health
Health utility of caregivers of children with autism was assessed by using the EuroQol five-dimensional (EQ-5D) questionnaire. Utility scores of autism caregivers were compared with norms for the general adult US population. Predictors of health utility were identified. A cross-sectional online s...



Maternal and Environmental Effects on Symbiont-Mediated Antimicrobial Defense
submitted by motgerl 1 hour ago - Topic: Biology
Bacteria produce a remarkable diversity of bioactive molecules with antimicrobial properties. Despite the importance of such compounds for human medicine, little is known about the factors influencing antibiotic production in natural environments. Recently, several insects have been found to bene...

Distinct subtypes of zona pellucida morphology reflect canine oocyte viability and cumulus-oocyte complex quality
submitted by 72796 1 hour ago - Topic: Biology
The aim of this study was to analyze surface morphology of the zona pellucida (ZP) and assess its relationship with oocyte viability, cumulus-oocyte complex (COC) quality, and oocyte donor age in dogs. Canine ovaries were sliced to release COCs for use in three experiments. In Experiment 1, oocyt...

Nonlinear percolation mechanisms in different storage-percolation modes in volcanic gas reservoirs
submitted by pwegener 1 hour ago - Topic: Geography
The non-linear seepage mechanisms in volcanic gas reservoirs were studied using experiment results of rate-controlled Hg penetration, nuclear magnetic resonance, and core displacement tests. According to types of storage space and throats, combined with dynamic production characteristics, the vol...

Evaluation of damage to horizontal wells through equivalent horizontal well length
submitted by pwegener 1 hour ago - Topic: Geography
The skin factor and additional pressure drop which are used to evaluate the formation damage of vertical wells can not accurately be applied to horizontal wells. A new model for evaluating formation damage of horizontal wells is presented. This method is derived by utilizing and modifying the con...
