As the pollution level is increasing, it becomes crucial for everyone to take preventive measures before going outdoors. ...
Whether you’re a musician, event organiser, sound engineer, or lighting designer, working in this industry can be both fulfilling and challenging.It’s essential, as in any industry, to take care of your health and safety, especially when it comes to noise. ...
TerraStryke Products LLC (TerraStryke) develop-distribute biostimulation additives proven to cost-effectively enhance chlorinated volatile organic compound (cVOC) biotransformation safely and completely. Our patented biostimulation additive ERDENHANCED leverages existing biogeochemical conditions to facilitate chlorinated alkane/alkene destruction. ERDENHANCED is proven to expedite residual mass ...
Most conventional sound measuring instruments cannot accurately capture such intense sound levels; noise dosimeters and sound level meters usually have a maximum measurement limit of about 140 to 146 dB SPL. ...
Also, the company offers software, which measures gamma and neutron radiation levels; airborne radioactivity levels; temperature and humidity in the facility; status of security doors; wind speed and direction; and barometric pressure. ...
Sound levels at the mixing console and in front of the speakers – where people are most heavily exposed – were also measured. ...
Cooling water systems play a critical role in the efficient operation of hydrocarbon processing facilities. Ensuring that these systems efficiently cool and condense the various process streams is essential to minimizing operating costs and maximizing plant performance and profitability. Common challenges to maintaining these systems at peak performance come in the form of corrosion, pitting and ...
The loggers are mounted directly on the pipeline with a magnetic connection to provide a good sound recording. It would often take this two-man crew five to ten days to find the leak in this large zone, driving an hour each way every day. ...
The size of the lock chambers at either end of the canal, the depth of the water in the canal and the height of the “Bridge of the Americas” actually limit the size of the vessels that can navigate the canal safely. This size limit is defined as “Panamax” and it has been used as a standard maximum vessel size for decades. ...
Passive Seismic Tomography Project Project Area: approximately 1000km2 (4700km2 with the peripheral stations) Seismic Network: 80 stations Recording Period: 5 months The scope of this project was the successful completion of a full Passive Seismic Tomography survey in Asmat – Papua, Indonesia, for subsurface mapping purposes and detection of possible hydrocarbon indications. In order ...
Zero-valent iron (ZVI) application in groundwater remediation is limited by its vulnerability to passivation, which significantly decreases its surface reactivity. Both biological and chemical processes can potentially passivate ZVI, although the understanding of biological passivation is limited. This study was conducted in bench-scale reactors packed with fresh ZVI or ZVI pre-exposed to ...
The application of the linear quadratic regulator (LQR) and fuzzy logic controller (FLC) in the field of active vibration isolation for a vehicle suspension system is presented to overcome the limitation of passive suspension system and the performances of the two active controllers are compared with the passive system. Results show that the performance of the LQR controller is better than the ...
