The Relationship

AbstractThe relationship between feeding rate and egg production of Coccinella trifasciata Mulsant and C. californica Mannerheim feeding on pea aphids, was investigated in the laboratory at 15.0°, 18.5°, 21.5°, and 25.5°C. Both species increase their feeding rate with increasing temperature above 13.6°C, with C. californica, the larger species, increasing its food consumption faster. C. californica also has the higher maintenance requirement but when food consumption is expressed relative to the beetles’ body weight, there is no difference between the species in either attribute. Coccinella californica converts excess food to eggs more efficiently than C. trifasciata.No significant influence of temperature on either the conversion rate or the maintenance requirement could be detected. The adverse effects of a very low feeding rate, whether due to restricted food supply or low temperature, influenced the beetles’ response to subsequent treatments.

The Common

Decreasing the temperature from 37° C. to 5° C. perceptibly and regularly increases hemolysis in hypotonic sodium chloride and cane sugar solutions, when the erythrocytes of a number of the common mammals are considered. The measurements were carried out with Smith's modification of the method of Hamburger. If following the original method of Hamburger one relies on the point of beginning hemolysis as an index of corpuscle resistance, the facts are not brought out clearly. The effect is in the opposite direction from that which would prevail if the laws governing change of osmotic pressure with change of temperature were the influential factors. The results possibly depend on some change in the permeability or consistence of the erythrocytic protoplasm considered as a semi-permeable membrane.

Atomic Form Factor

Temperature affects both elastic and inelastic scattering of electrons in a crystal. The Debye-Waller factor, B, describes the influence of temperature on the elastic scattering of electrons, whereas the imaginary part of the (complex) atomic form factor, fc = fr + ifi, describes the influence of temperature on the inelastic scattering of electrons (i.e. absorption). In HRTEM simulations, two possible ways to include absorption are: (i) an approximate method in which absorption is described by a phenomenological constant, μ, i.e. fi; - μfr, with the real part of the atomic form factor, fr, obtained from Hartree-Fock calculations, (ii) a more accurate method in which the absorptive components, fi of the atomic form factor are explicitly calculated. In this contribution, the inclusion of both the Debye-Waller factor and absorption on HRTEM images of a (Oll)-oriented GaAs crystal are presented (using the EMS software.Fig. 1 shows the the amplitudes and phases of the dominant 111 beams as a function of the specimen thickness, t, for the cases when μ = 0 (i.e. no absorption, solid line) and μ = 0.1 (with absorption, dashed line).
