Constancy in an inconstant world: moving beyond constant temperatures in the study of reptilian incubation.
Variable environmental conditions can alter the phenotype of offspring, particularly in ectothermic species such as reptiles. Despite this, the majority of studies on development in reptiles have been carried out under constant conditions in the laboratory, raising the question of just how applicable those investigations are to natural conditions? Here, we first review what we have learned from...

متن کاملDetermination of the Binding Constant of Terbium-Transferrin
Apotransferrin (apo Tf) in 0.1 M N-(2hydroxyethyl)piperazine-N2-ethanesulfanic acid at 25 ˚C and pH 7.4 has been titrated with acidic solution of Tb3+. The binding of Tb3+ at the two specific metal-binding sites of transferrin was followed from the changes in the difference UV spectra at 245 nm. The molar absorptivity per binding site for Tb3+...
متن کاملDetermination of the Stability Constant of Vanadium (V) with Alaine
Formation equilibria of dioxy vanadium (V) complex with alanine in acidic media (pH<2.3) has been investigated potentiometrically and spectrophotometrically. In this condition the 1:1 complex has the formula VO2Y, where Y¯ represent the fully dissociated aminocarboxylate anion. The stability constant of VO2Y was determined as log KVO2Y=11.32±<e...
متن کاملImprovements of Young inequality using the Kantorovich constant
Some improvements of Young inequality and its reverse for positive numbers with Kantorovich constant $K(t, 2)=frac{(1+t)^2}{4t}$ are given. Using these inequalities some operator inequalities and Hilbert-Schmidt norm versions for matrices are proved. In particular, it is shown that if $a, b$ are positive numbers and $0 leqslant nu leqslant 1,$ then for all integers $ kgeqsl...
