the feasibility of noise control in a soft drink plant
results according to the study results, noise levels in a co2 plant’s house and control room ranged from 88 to 102 db and 79 to 82 db (a), respectively. in order to reduce the amount of emitted noise in the co2 plant house and control room, a noise control plan was implemented in each part of the facility; it was met with effective results. conclusions the findings of this investigation have cl...
متن کاملSmart foams: switching reversibly between ultrastable and unstable foams.
Fatty acids are surfactants of particular interest in the present context of green chemistry since they can be extracted from agricultural resources. Here we report on the formation of multilayer tubular structures made of ethanolamine salt of 12-hydroxy stearic acid [1-2]. By visual observations, we have demonstrated that these tube solutions produced foams outstandingly stable over months at ...
متن کاملFeasibility of BCI Control in a Realistic Smart Home Environment
Smart homes have been an active area of research, however despite considerable investment, they are not yet a reality for end-users. Moreover, there are still accessibility challenges for the elderly or the disabled, two of the main potential targets for home automation. In this exploratory study we design a control mechanism for smart homes based on Brain Computer Interfaces (BCI) and apply it...
متن کاملPlatoon Control Using VLC: A Feasibility Study
The major benefits of driving vehicles in controlled close formations such as platoons are that of increasing traffic fluidity and reducing air pollution. While vehicle-to-vehicle (V2V) communications is requisite for platooning stability, the existing radio communications technologies (e.g., the IEEE 802.11p) suffer from poor performance in highly dense road scenarios, which are exactly to be ...
متن کاملInvestigating the Effect of Workplace Noise Exposure on Cardiovascular Disease Risk Factors: A Case-Control Study
Background and Aim: Occupational exposure to noise in the workplaces is a significant health problem and cardiovascular disease is one of the most important and common non-communicable diseases and one of the main causes of premature death. In addition to hearing impairments, noise as a stressor may cause cardiovascular problems, high blood pressure, nerve stimulation, stress and hormonal dis...
