Utilizing these effects, the neonate can gain up to 90% of the thrust needed to move alongside the mother at speeds of up to 2.4 m/s.
Conclusions A theoretical analysis, backed by observations of free-swimming dolphin schools, indicates that hydrodynamic interactions with mothers play an important role in enabling dolphin calves to keep up with rapidly moving adult school members. This is an Open Access article: verbatim copying and redistribution of this article are permitted in all media for any purpose, provided this notice is preserved along with the article's original URL During the late 2000s, due to the influence of computer storage and retrieval systems such as the Internet, some scientific publications, primarily those published by Elsevier, started including graphical abstracts alongside the text abstracts.
The graphic is intended to summarize or be an exemplar for the main thrust of the article.
Once papers are chosen based on the abstract, they must be read carefully to be evaluated for relevance.
It is generally agreed that one must not base reference citations on the abstract alone, but the content of an entire paper.
The abstract can convey the main results and conclusions of a scientific article but the full text article must be consulted for details of the methodology, the full experimental results, and a critical discussion of the interpretations and conclusions.
An abstract allows one to sift through copious numbers of papers for ones in which the researcher can have more confidence that they will be relevant to his or her research.Example taken from the Journal of Biology, Volume 3, Issue 2.: by Daniel Weihs, Faculty of Aerospace Engineering, Technion, Israel Institute of Technology, Haifa 32000, Israel.Abstract: Background Drafting in cetaceans is defined as the transfer of forces between individuals without actual physical contact between them.A study of the hydrodynamics of drafting, initiated inmechanisms causing the separation of mothers and calves during fishing-related activities, is reported here.Results Quantitative results are shown for the forces and moments around a pair of unequally sized dolphin-like slender bodies. First, the so-called Bernoulli suction, which stems from the fact that the local pressure drops in areas of high speed, results in an attractive force between mother and calf.An abstract is a brief summary of a research article, thesis, review, conference proceeding, or any in-depth analysis of a particular subject and is often used to help the reader quickly ascertain the paper's purpose.When used, an abstract always appears at the beginning of a manuscript or typescript, acting as the point-of-entry for any given academic paper or patent application.Second is the displacement effect, in which the motion of the mother causes the water in front to move forwards and radially outwards, and water behind the body to move forwards to replace the animal's mass.Thus, the calf can gain a 'free ride' in the forward-moving areas.This behavior has long been surmised to explain how young dolphin calves keep up with their rapidly moving mothers.It has recently been observed that a significant number of calves become permanently separated from their mothers during chases by tuna vessels.
