In 1950, a quarter of a century after his first-ever nonlinear optical experiment when intensity-dependent absorption was observed in uranium-doped glass, Sergey Vavilov predicted that birefringence, dichroism and polarization rotatory power should be dependent on light intensity. It required the invention of the laser to observe the barely detectable effect of light intensity on the polarizati...

We generalize ∇(A), which was introduced in [Sch∞], to larger cardinals. For a regular cardinal κ > א0 we denote by ∇κ(A) the statement that A ⊆ κ and for all regular θ > κ, {X ∈ [Lθ[A] ] <κ : X ∩ κ ∈ κ ∧ otp(X ∩ Ord) ∈ Card} is stationary in [Lθ[A] ] . It was shown in [Sch∞] that ∇א1(A) can hold in a set-generic extension of L. We here prove that ∇א2(A) can hold in a set-generic extension of L...

Let C[[x1, . . . ,xn]] (brie£y C [[x]], where xˆ (x1, . . . ,xn) is the vector of indeterminates) be the ring of formal power series in n indeterminates x1, . . . ,xn with complex coe¤cients.We consider in this paper formal power series transformations F by which we understand automorphisms F of C[[x]] which are continuous with respect to the order topology (i.e., order preserving) and leave ev...

The optical rotatory dispersion (ORD) and circular dichroism of the conformationally flexible carvone molecule has been investigated in 17 solvents and compared with results from calculations for the "free" (gas phase) molecule. The G3 method was used to determine the relative energies of the six conformers. The optical rotation of (R)-(-)-carvone at 589 nm was calculated using coupled cluster ...

Bovine mercaptalbumin has been modified at the carboxyl groups by means of I-ethyl-3 (3-dimethylisopropyl) carbodiimide and glycine amide. A stable derivative was obtained after modification of 54 groups. The modified protein differed only slightly from the unmodified one with respect to the optical rotatory dispersion parameters ao, bo and ~. This preparation was studied in the analytical ultr...

We present the first µSR measurements ever performed on elemental Pu, and set the most stringent upper limits to date on the magnitude of the ordered moment µ ord in α-Pu and δ-stabilized Pu (alloyed with 4.3 at. % Ga). Assuming a nominal hyperfine coupling field of 1 kOe/µB we find µ ord ≤ 10 −3 µB at T ∼ = 4 K.

The experimental vibrational circular dichroism, electronic circular dichroism, and optical rotatory dispersion spectra and corresponding quantum chemical predictions of 3,3'-diphenyl-[2,2'-binaphthalene]-1,1'-diol (VANOL) are used to confirm its absolute configuration as (+)(589)-(aR) or (-)(589)-(aS). A discrepancy in the literature crystal structure has been resolved by determining the X-ray...

When the SH groups of various derivatives of human haemoglobin are converted into their mercuric mercaptides small changes are observed in the optical rotatory dispersion in the range 385-294mmu. These changes are proportionately greater for the reactive than for the unreactive SH groups. These observations have been interpreted in terms of the conformational changes that are likely to occur in...

The main objective of this study is to propose a methodology to build a parametric linear model of Flexible Multibody Systems for control design. This approach uses a combined Finite Element State Space Approach based on component modes synthesis and double-port approach. The proposed scheme offers the advantage of automatic assembly of substructures, preserving the elastic dynamical behavior o...

Fever: a Clinical Study. By T. J. Maclagan, M.D. London: J. & A. Churchill. 1888. Dr. Maclagan has above all things the pen of a ready writer, and this book forms no exception in respect of quality to his previous publications. It is so pleasant to peruse a book whose grammar is irreproachable, and style attractive. In the space of something over 160 pages, Dr. Maclagan enunciates his theories ...
