BACKGROUND U.S. natural gas production increased 40% from 2000 to 2015. This growth is largely related to technological advances in horizontal drilling and high-volume hydraulic fracturing. Environmental exposures upon impacted communities are a significant public health concern. Noise associated with natural gas compressor stations has been identified as a major concern for nearby residents, t...

Background. Intraocular gas bubbles are commonly used in retinal surgery. There are specific management guidelines that need to be followed to ensure surgical success, and there are also unique ophthalmic and systemic complications that can occur in such patients. Objective. To educate emergency department personnel about important issues in the management of patients who have a gas-filled eye ...

Interviews and questionnaires are very important techniques to acquire information from the potential user. Surveys are one tool to understand users’ needs which is in particular helpful in the early phases of user interface design processes. To get meaningful information interface designers typically determine the target user group for an application. Most commonly, when designing in-car inter...

Owing to environmentally-destructive impact of aromatic hydrocarbons, such as benzene, benzene ethyl, toluene, and xylenes or BTEXs, these materials are classified as hazardous pollutants in the air. This study studies cancer and non-cancer risk in District 12 of Tehran Municipality, through these components for two groups of employees or storekeepers and gas station customers.
