(To maximize lift and finesse, a pilot needs to find the perfect "angle of attack" — the best position of the wings in relation to the wind).
The present study identified such differing modes of connections for different aspects of butterfly wing patterns in relation to external temperature and to internal levels of ecdysone.
We have analyzed theoretical and empirical studies about upbringing in Muslim families and the content and style of education of parents with (extreme) right-wing sympathies in relation to radicalization of their adolescent children.
How are the wings placed in relation to the fuselage, and how much do they sweep rearwards?
Thus, while radicalising cultural authoritarianism, right-wing populism often takes on board left wing social values in relation to social security and equality.
In an airplane, the flight path of the wing is fixed in relation to its forward flight; in a helicopter, the flight path of the rotor advances forward (to the helicopter's nose) and then rearward (to the helicopter's tail) in the process of its circular movement.
Slender and more pointed wings and shorter tails in relation to the wing reduce the induced drag at the wings considerably and are known to produce a larger forward component in flight during migration [1] [3], [8].
Among different populations of blackcaps, Sylvia atricapilla, Fiedler [13] found with increasing migratory distance: (1) an increase in wing length, aspect ratio and wing pointedness; (2) a decrease in wing-load; (3) relatively shorter slots on the wing-tip; (4) a shorter alula in relation to wing length; and (5) a shorter tail in relation to wing length.
Birds with longer migratory pathways possess relatively longer, more pointed, and more slender wings, shorter emarginations on the wing tip, and show relatively shorter tails in relation to wing length and a more forked tail.
The more slender and pointed wings and the shorter tail in relation to the wing reduce the induced drag at the wings and produce greater uplift and thrust [2], [3].
