This study explores the impact of COVID-19 on travellers’ future recreational vehicle, cabin and tent camping decisions extending construal level theory. Findings suggest that considera...

to study the spatial and temporal variation of nitrate pollution in groundwater in the vicinity of zayandehrud river in isfahan province monthly water samples were collected from 100 wells in the study area. the average n03-n concentration ranged from 1.2 to 25.7 mg/l (5.4 to 115.6 mg/i as no3) and average n03-n concentration in groundwater was 9.6 mg/i, which is lower than the standard limit (...

Retreating ice spills secrets Thanks to climate change, glacial archaeology is a burgeoning field. It involves rescuing artifacts, the past’s secrets, as they melt out of high-mountain ice. You might call it new icy frontier. Each year, from August through September—peak season, hikers may know—a group hardy archaeologists and trusted helpers based in Innlandet, Norway, makes strenuous chilly t...

This study examines the groundwater quality in wells situated near agricultural fields in Saudi Arabia. Fruits (e.g., tomato and green pepper) irrigated with groundwater were also assessed for the occurrence of opportunistic pathogens to determine if food safety was compromised by the groundwater. The amount of total nitrogen in most of the groundwater samples exceeded the 15 mg/L permissible l...

The exciton dynamics in In0.15Ga0.85As/GaAs quantum wells grown on (111)B and (100) GaAs substrates are studied by the time-resolved photoluminescence (PL). We have found that the piezoelectric fields in (111)B samples affect the transient behavior of PL spectra. Compared with the reference (100) samples, we have confirmed that the piezoelectric effect induces slower exciton relaxation in (111)...

Coal bed methane (CBM) is generated primarily through the microbial degradation of coal. Despite a limited understanding of the microorganisms responsible for this process, there is significant interest in developing methods to stimulate additional methane production from CBM wells. Physical techniques including hydraulic fracture stimulation are commonly applied to CBM wells, however the effec...
