One means to support for design-by-analogy (DbA) in practice involves giving designers efficient access to source analogies as inspiration to solve problems. The patent database has been used for many DbA support efforts, as it is a preexisting repository of catalogued technology. Latent Semantic Analysis (LSA) has been shown to be an effective computational text processing method for extractin...

OBJECTIVES To study exposure to noise, the attitudes and knowledge towards noise-induced hearing loss and the actual use of hearing protection in a steel rolling mill in Nigeria. METHODS A structured questionnaire was administered to 116 randomly selected workers to collect information relating to their knowledge and attitudes towards hazardous occupational noise and preventative measures. No...

In this article, we propose Design-by-Analogy (DbA) as an approach with the potential to effectively support designers’ creativity during ideation stage for design problems from Product, Service or Product Service Systems (PSS). We start by contrasting natural evolution and selection of species to economical human systems survival, where the options for companies are adaptation or mutation, whe...

Major gene effects on traits associated with substance use disorders are rare. Previous findings in methamphetamine drinking (MADR) lines of mice, bred for high or low voluntary MA intake, and in null mutants demonstrate a major impact of the trace amine-associated receptor 1 (Taar1) gene on a triad of MA-related traits: MA consumption, MA-induced conditioned taste aversion and MA-induced hypot...

Prenatal exposures to polycyclic aromatic hydrocarbons (PAHs) are associated with adverse outcomes including small for gestational age infants. We have previously reported differential levels of PAHs in the placenta preterm delivery. found that a specific PAH, dibenzoanthracene (DBA), was significantly higher than either benzo[a]pyrene (BaP) or Benzo[b]fluoranthene (BbF). Furthermore, we placen...

The present study verified the sound pressure levels inside incubators and at the Neonatal Intensive Care Unit, six months after the implementation of an educational program. Quantitative and descriptive study carried out at the Neonatal Intensive Care Unit and inside the incubators of a hospital. It was registered 151 hours and 30 minutes of sound pressure levels at the Neonatal Intensive Care...

Background: Noise pollution is one of the common physical harmful factors in many work environments. The current study aimed to assess the personal and environmental noise level and project the sound map of an Iranian tire manufacturing complex using Surfer V.14 and Noise At Work tools. Materials and Methods: This descriptive study was conducted in the curing hall [including curing, sandblast,...
