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...

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. By measuring pol...

The present sought to draw a comparison between Model Predictive Control performance and two other controllers named Simple PI and Selective PI in controlling large-scale natural gas transport networks. A nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in SIMULINK® environment of MATLAB®. Control schemes were designed to provide a s...

Exposure to the lead is public health problem and threat to environment with proven harmful impact on human, including industrial workers and general population. Harmful impacts of exposition to nervous, endocrine, hematological, cardiovascular, immune and reproductive system to the lead are well known. This article addresses the results of retrospective research carried out with attendants at ...

Giant-cell interstitial Pneumonia (GIP) is a very uncommon respiratory disease. The majority of cases of GIP are caused by exposure to cobalt, tungsten and other hard metals. In this report, we describe GIP in a patient who worked in gas station and dealt in propane gas vessels. He presented with clinical features of chronic interstitial lung disease and underwent an open lung biopsy that showe...

In the gas station problem we want to find the cheapest path between two vertices of an n-vertex graph. Our car has a specific fuel capacity and at each vertex we can fill our car with gas, with the fuel cost depending on the vertex. Furthermore, we are allowed at most ∆ stops for refuelling. In this short paper we provide an algorithm solving the problem in O(∆n2 + n2 logn) steps improving an ...
