Although this method involves more work, case studies have indicated that no-till farming greatly reduces erosion.
As proposed, this method involves more cost and greater complexity, which means it is not the best choice.
Although this method has been renewed a few times, there is a need to update this method involving more thorough statistical methods.
The unprecedented survey, carried out by Allen's company Vulcan with £7m of funding, is the first continent-wide aerial survey of African elephants using standardised data collection and technical validation methods, involved more than 90 scientists, six NGOs and many volunteers and conservationists on the ground.
Most of the above-mentioned methods involved more than one measurement and were too cumbersome.
Other disposal methods involve more tunneling, such as within salt, which has particularly good ability for shielding against radiation.
However, most of these methods involve more than one step, high energy requirement, low material conversions, difficulty in purification, and hazardous chemicals [13].
On the other hand, Free-Report Protocols and Think- Aloud Protocols have the advantage as compared to other information acquisition methods, involving more asking specific questions to the doctors, that they are minimally affected by the investigator's expectations.
Another study by Harewood et al [ 11] reported that survey methods that involved more personal interaction such as on-site surveys and phone interviews tend to generate higher response rates than less personal methods such as mail back surveys and electronic mail surveys.
The tradeoff, however, is that both the spectral homotopy analysis method and the successive linearisation method may involve more computations per step compared to the methods in the literature.
