Proline content of sugar beet storage roots: Response to water deficit and nitrogen fertilization at field conditions
(Elsevier, 2007-06)
Drought stress is one of the major factors causing profit loss of the sugar beet crop. The accumulation of proline, an indicator of water stress, has been reported in response to osmotic and salt stress in sugar beet leaves, ...

Ball Milling of Fe83Zr6B10Cu1 Amorphous Alloy Containing Quenched in Crystals
(Elsevier, 2007)
A Fe83B10Zr6Cu1 melt-spun amorphous alloy has been ball milled in the presence of partially crystalline ribbon pieces, in order to speed up its mechanical nanocrystallization process. Microstructure and magnetic properties ...

The 1-type of a Waldhausen K-theory spectrum
(Elsevier, 2007-12-01)
We give a small functorial algebraic model for the 2-stage Postnikov section of the K-theory spectrum of a Waldhausen category and use our presentation to describe the multiplicative structure with respect to biexact functors.

A Direct Extension of the Avrami Equation to Describe the Non-isothermal Crystallization of Al-base Alloys
(Elsevier, 2007)
A direct extension of the Avrami equation considering the temperature dependence of the frequency factor is applied to describe the crystallization of a series of Al-Mm-Ni-Co amorphous alloys (Mm is a mischmetal). For high ...

Valuations in algebraic field extensions
(Elsevier, 2007-06-15)
Let K → L be an algebraic field extension and ν a valuation of K. The purpose of this paper is to describe the totality of extensions {ν′} of ν to L using a refined version of MacLane’s key polynomials. In the basic case ...

Thermal and Microstructural Dependence of the Initial Permeability of Co60Fe18Nb6(B,Cu)16 Alloys
(Elsevier, 2007)
The thermal and microstructural dependence of the initial permeability of Co60Fe18Nb6B16-yCuy (y = 0, 1) alloys have been studied. The comparison of kinetics and microstructural data of the two compositions indicate the ...

Triangulated categories without models
(Springer, 2007-11)
We exhibit examples of triangulated categories which are neither the stable category of a Frobenius category nor a full triangulated subcategory of the homotopy category of a stable model category. Even more drastically ...

Shape phase transition in odd nuclei in a multi- j model: The UB(6) ⊗ UF(12) case
(The American Physical Society, 2007)
The phase transition in odd nuclei when the underlying even-even core nuclei experience a transition from spherical to deformed γ-unstable shapes is investigated. The odd particle is assumed to be moving in the three ...
