Siwa Oasis is a tectonically induced depression located in the northern part of the Western Desert. It is intensively characterized by salt mineralization and salt pans. This paper aims to investigate the evaluation of salts from the near-surface underground water in Siwa Oasis to assess the quality of salt for several uses. The study results show that …

Seawater (n = 27) and salt samples (n = 27) were collected in 1000 mL acid-washed plastic bags during September 2019.Sea salt is extruded from water through slow evaporation at 30 °C to 40 °C and stored in zip lock bags. For the analysis of heavy metals, salt samples were ground to powder using a mortar and pestle and digested in acid …

Degree of salt stress can affect the different crops differently. For rice, soil salinity beyond ECe ~ 4 dS/m is considered moderate salinity while more than 8 dS/m becomes high. Similarly pH 8.8 - 9.2 is considered as non-stress while 9.3 9.7 as moderate stress and equal or greater than 9.8 as higher stress.

The patients were assigned to the control and experimental groups (1-warm salt-water and 2-cold salt-water) following the randomization checklist. While control groups did not receive any interventions, the patients in the salt-water group were asked to apply warm (41 °C) or cold-water (23–26 °C) baths to their hands/feet for 30 min every ...

Salt-water intrusion (SWI) is a worldwide problem increasingly affecting coastal aquifers, exacerbated by climate changes and growing demand of fresh-water. Therefore, research on this topic using both …

One of the most common coatings technologies for salt water pipelines is the FBE (Wei et al., 2007). It is a high performance anti -corrosion coating that provides good protection for s mall and ...

Abstract. The international Thermodynamic Equation of Seawater 2010 (TEOS-10) defined the enthalpy and entropy of seawater, thus enabling the global ocean heat content to be calculated as the volume integral of the product of in situ density, ρ, and potential enthalpy, h0 (with reference sea pressure of 0 dbar). In terms of Conservative …

Saltwater intrusion into coastal aquifers menace multiple coastal areas globally, degrading groundwater quality, which poses an important threat to freshwater supply for agricultural, industrial and domestic utilization. Groundwater over-exploitation used to be commonly recognized as the principle factor causing saltwater intrusion, …

Seawater intrusion associated with lowering of groundwater levels is an important issue in many of California's coastal groundwater basins. The U.S. Geological Survey (USGS) uses data collection, modeling tools, and scientific analysis to help water managers plan for, and assess, hydrologic issues that can cause 'undesirable results' associated with …

Revenues streams to SWD operators consist primarily of disposal fees – typically in the range of $0.50 to $2.50 per barrel – and skim oil sales. Produced water contains significant amounts of suspended crude oil that the SWD facility "skims-off" (by various methods) and sells to increase revenues. Where disposal services are abundant ...

This will cause ~40–50% of the agricultural area to be affected by salt water even during the rainy season, seriously affecting rice crops. ... There is no general law for incorporating statistical measurements into model evaluation. The background of the hypothesis or prediction is critical, and the observations of the metric will evolve ...

Osmosis- Evaluation + Conclusion. In our test we put six different sliced up potatoes chips in solutions. The solution was different concentration of salt and water, one was 5% sugar, one 10%, one 15%, one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution.

55 sites at which saltwater and (or) gas were present in the groundwater (appendix 1) were inventoried by Randall (1972) as part of valley-fill aquifer investigations in the 1960s and 1970s. The presence of saltwater was reported by drillers or well owners based on taste tests or was determined by water-
