Sentence examples for impact of extraction from inspiring English sources

Establishing specific resource efficiency targets for materials where scarcity looms or the environmental impact of extraction is serious – rare earth metals being a case in point.

A central composite rotatable design was used to analyse the impact of extraction parameters (temperature, time and pressure) and a response surface methodology was used to obtain optimal extraction conditions for the maximum oil yield.

While the impact of extraction and non-extraction treatment on the soft tissue response, smile esthetics, stability, and other parameters has been extensively investigated [1 3], the literature is rather inconclusive with regard to the impact of the extractions on the vertical dimension.

A 3 level, 3 factor Box Behnken Design was used to investigate and optimize the impact of extraction time (20, 40, 60 min), temperature (30, 45, 60 °C) and induced calorimetric power (38.50, 53.25, 68.00 W) on total phenolic content (TPC), total flavonoid content (TFC), Ferric reducing/antioxidant power assay (FRAP) and half maximal inhibitory concentration (IC50) of bitter gourd (BG) extract.

This study examined the impact of extraction temperature, duration and solvent (petroleum ether) to leaf proportions on the recovery of artemisinin from leaf steeped in solvent, in a central composite design (CCD), and the results were used to generate both a response surface methodology (RSM) model and an artificial neural network (ANN) model.

The impact of extraction on the environment is not an inevitable consequence to be regretted but not addressed.

In the long-lasting debate of extraction versus non-extraction treatment, the impact of extractions on the skeletal vertical dimension remains rather unclear.

In studies assessing the impact of extractions on the vertical dimension, the initial crowding ranges from slight to severe [8, 24, 28, 29], while in most studies, it is not reported [9, 12, 15, 17, 18, 30, 32].

But Cameron -- who also visited Vietnam, Indonesia and Malaysia -- just like other leaders, demonstrated far less concern for the threatened habitats of Southeast Asia, or the impacts of extraction and harvesting operations in one of the world's most fragile and biodiverse regions.

The authors say that we need better ways to estimate how much gas is in the ground and how much of it can be extracted, along with reducing the environmental impact of certain extraction practices.

Recently, in the oil and gas extraction and transportation field, much attention has been paid both to increase efficiency and to reduce the environmental impact of the extraction techniques that, by now, consists mainly on Enhanced Oil Recovery processes based on gas or water injection into the reservoirs.
