The roots of land plants associate with microbes, including fungal symbionts that can confer abiotic stress tolerance. Bitumen extraction following oil-sand surface mining in the Athabasca region of Alberta, Canada removes plant nutrients but leaves a petrochemical residue, making the coarse tailings (CT) hostile to both plants and microbes. We isolated an endophyte strain of the Ascomycete Tri...
Input-output modeling and multiplier analysis are used to assess Taiwan's five petrochemical industries, based upon their economic contribution and potential impacts on energy consumption and CO2 emission. In addition, a consolidated index system was developed for evaluating energy and economic efficiencies as well as targets for CO2 reduction. Results indicate that petrochemical materials (PM)...
the establishment of good process safety management (psm) is widely considered as the most effective means of improving safety levels in process industries. this study was conducted to evaluate the feasibility of establishing and implementing psm requirements based on occupational health and safety assessment series 18001 standards (ohsas 18001) and health, safety and environment management sys...
Effects of different pretreatment methods on sludge dewaterability and polycyclic aromatic hydrocarbons (PAHs) degradation during petrochemical sludge anaerobic digestion were studied. Results showed that the total biogas production volume in the thermal pretreatment system was 4 and 5 times higher than that in the ultrasound pretreatment and in the control system, and the corresponding volatil...
[1] Airborne formaldehyde (CH2O) measurements were made by tunable diode laser absorption spectroscopy (TDLAS) at high time resolution (1 and 10 s) and precision (±400 and ±120 parts per trillion by volume (pptv) (2s), respectively) during the Texas Air Quality Study (TexAQS) 2000. Measurement accuracy was corroborated by in-flight calibrations and zeros and by overflight comparison with a grou...
BACKGROUND Humans living near industrial point emissions can experience high levels of exposures to air pollutants. Map Ta Phut Industrial Estate in Thailand is the location of the largest steel, oil refinery, and petrochemical factory complexes in Southeast Asia. Air pollution is an important source of oxidative stress and reactive oxygen species, which interact with DNA and lipids, leading to...
The aim of this study was to investigate the effect of Strengths-Based leadership on employee’s job crafting with the mediating role of psychological capital and learning. The correlation-descriptive research method has been used. All the employees of National Petrochemical Company (N=500) comprised the statistical population of the present study and 217 individuals were randomly selected as th...
