On non-rigid del Pezzo fibrations of low degree

We consider $\mathbb{P}(1,1,1,2)$ bundles over $\mathbb{P}^1$ and construct hypersurfaces of these bundles which form a degree 2 del Pezzo fibration over $\mathbb{P}^1$ as a Mori fibre space. We classify all such hypersurfaces whose type \III or \IV Sarkisov links pass to a different Mori fibre space. A similar result for cubic surface fibrations over $\mathbb{P}^2$ is also presented.Comment: 34 page

Acts of the State and Representation in Edith Stein

This paper discusses the thesis defended by Edith Stein that certain acts can be attributed to the State. According to Stein, the State is a social structure characterized by sovereignty. As such, it is responsible for the production, interpretation, and application of law. These tasks require the performance of acts, most of which are what Stein calls “social acts” like enactments and orders. For Stein, the acts in question are made by the organs of the State, but in the name of the State, and are thus attributed to the State via a relation of representation. In the first section, the paper presents Stein’s thesis that the sovereignty of the State entails a series of legal prerogatives, which in turn result in various social acts being ascribed to the State through its representatives. In the second section, the paper critically discusses Stein’s views, notably her theory of representation, and her account of the nature of the State, while emphasizing its most interesting aspects, namely, its fine-grained analyses of the various acts that are attributed to the State

Kant’s Antinomy of Teleology: In Defense of a Traditional Interpretation

Kant’s Antinomy of Teleological Judgment is unique in offering two pairs of oppositions, one of regulative maxims, and the other of constitutive principles. Here I defend a traditional interpretation of the antinomy— as proposed, for example, by Stadler (1874), Adickes (1925), and Cassirer (1921)—that the antinomy consists in an opposition between constitutive principles, and is resolved by pointing out their legitimate status as merely regulative maxims. I argue against recent interpretations—for example, in McLaughlin (1990), Allison (1991), and Watkins (2009)—which treat the regulative pair as itself antinomial. I then address several textual worries having to do with reconciling the traditional interpretation within the overall structure of the Dialectic of Teleological Judgment that have led these scholars to espouse the new view. Throughout the paper, I emphasize hitherto neglected parallels with Kant’s treatment of the antinomy of taste, which sheds light on understanding the antinomy of teleology

Composite Construction. Many structural systems that can not be easily categorized according to the material used. Composite beam system as we often encounter. In this case, steel is the part that in-place first, then cast in concrete around the shear connectors onnector shear above the steel beams. The presence of shear connectors caused the steel beams and concrete works integrally thereon. Thus forming a T section with steel as part of the experience tensile, and concrete that had hit. This study is intended to introduce more closely on the implementation of LRFD method, which is packaged in a handbook issued by (AISC) as Load and Resistance Factor Design Specification for Structural Steel Buildings, which enforces security is not just one factor alone but is broken into and the load factor strength reduction factor that gives a design of steel construction that is safe, convenient and economical enough. From the analysis, the calculation can be concluded for the construction of composite floor without the support obtained 140 mm thick plate, use 22 gage steel deck profiles (t = 0.75 mm) 75 mm Lok Floor. The use of steel deck profiles are intended as a substitute for the need of reinforcing the field, as well as permanent begisting in a design. The dimensions required when the beam receive workload, diperole dimensional beam direction (y): WF 350 x 175 x 7 x 11, for the main beam direction (y): WF 600 x 300 x 12 x 20, main beam direction (x ): WF 500 x 300 x 11 x 15, and cantilever beam direction (y): WF 350 x 175 x 7 x 11, the cantilever beam direction (x): WF 400 x 200 x 8 x 13, and used the interface shear sliding connector stud 19 x 125 mm in diameter. While the dimensions required when the column receiving the axial load and bending, obtained by column dimensions 609.6 x 588.8 x 15.9 mm with a type of rectangular HSS
