A fast and convenient protocol for the synthesis of novel spiro[dihydropyridine-oxindole] derivatives in satisfactory yields was developed by the three-component reactions of arylamine, isatin and cyclopentane-1,3-dione in acetic acid at room temperature. On the other hand the condensation of isatin with two equivalents of cyclopentane-1,3-dione gave 3,3-bis(2-hydroxy-5-oxo-cyclopent-1-enyl)oxindole in high yields. The reaction mechanism and substrate scope of this novel reaction is briefly discussed.

Ketene Acetal

The behaviour of various types of polar dienes towards halogenated ortho quinones has been investigated in a number of representative cases. As compared to the commonly used para analogues, o-quinones provide a wide range of products that indicate a keener response to the nature, number, and position of substituents on both reactants. 3-Halogenated-o-naphthoquinones 1 and 2 react smoothly with a representative vinologous ketene acetal 3, vinylketene acetals 4 and 5, and a monooxygenated diene 6 to provide variously substituted phenanthrenequinones 7–11. Only monooxygenated dienes on the other hand add to o-benzoquinones 14–16 and give convenient syntheses of the corresponding o-naphthoquinones 18–20. Keywords: cycloaddition, o-naphthoquinones, phenanthrenequinones, regiospecificity.

Abstract Reexamination of a wide range of documents surrounding the twenty-second, twenty-fourth, and twenty-fifth sessions of the Council of Trent reveals that delegates strived officially to say as little as possible about music: only that secular or impure elements should be eliminated and that specific issues should be settled locally, by individual bishops and provincial synods. But, beginning with Gustave Reese, several scholars have misleadingly strung together a preliminary canon, stressing textual intelligibility, which was never approved in the general congregations, and the few lines that actually supplanted it, concerned only with the elimination of lasciviousness. On the other hand, a largely unrecognized or misunderstood attack on church polyphony did occur at the less familiar twenty-fifth session, when Gabriele Paleotti may have attempted to suppress elaborate music in female monasteries. Although this attempt was rejected in the general congregations, its restrictions were subsequently revived by local authorities such as Paleotti and Carlo Borromeo in their own dioceses. In the Council's immediate aftermath, reformers such as Paleotti and Borromeo once again focused on the issue of intelligibility, affording it a quasi-official status that seems to have quickly become widely accepted as “iuxta formam concilii.”

Dispute Resolution System

ADR (Alternative Dispute Resolution), as a non-judicial resolution of disputes, is a wide range of mechanisms that aim to put an end to a conflict without the need of conducting a trial before the court. On the other hand, the modern form of ADR is ODR (Online Dispute Resolution) – an online dispute resolution system that is the expression of the newest means of communication and technical innovations in order to help in non-judicial dispute resolving. The goal of this publication is to present the ODR platform and, in particular, to describe the process of filing a complaint by the consumer by means of it.

This chapter examines Hegel’s lectures on the history of modern philosophy in view of the tension between, on the one hand, his ambition to grasp philosophy’s past in a truly philosophical way and, on the other hand, the necessity to account for the actual particularities of a wide range of philosophical systems. Hegel’s lectures are put in relief by comparing their methodological principles to those put forward by his Kantian predecessor Tennemann. After discussing Hegel’s conception of modern philosophy as a whole, the chapter turns to his reading of Locke, Leibniz, and, in particular, Kant. In this context, it also compares Hegel’s assessment of Kant’s achievements to that of Tennemann. The chapter concludes by considering Hegel’s account of the final moment of the history of philosophy.

Nowadays, mobile devices, such as smartphones, tablets or smartwatches, are essential items in our daily life. Further, more and more people use smart mobile devices in their everyday work for remote controlling, observing diagrams, performing web analytics, etc. However, the full potential of mobile devices is not tapped yet; built-in sensors such as accelerometers or gyroscopes offer a wide range of interaction capabilities, which are still often not fully used in nowadays mobile applications. On the other hand, desktops are still the dominating working device, but with significantly differing interaction means. With additional hand tracking devices capturing the user's gestures additional input possibilities are available but still often unused. In this paper, we investigate on a concept for orientation-based touch-less interaction. Depending on the type of device - traditional desktop or a mobile device - we use an interaction metaphor called "Waggle"; utilizing of tilting and turning of either the user's hand or the mobile device itself for additional input possibilities. Based on the results of two pilot studies for both environments, basic parameters for future design decisions are derived: on the one hand, the maximum angle for basic rotation axes are evaluated. On the other hand, different discretizations of tilt and turn angles are investigated. Based on the outcome of both studies the optimal configuration for the use of the Waggle interaction metaphor in future applications on both mobile and desktop environments are defined.

AbstractFor world literature studies, Indian writing in English offers an exceptionally rich and variegated field of analysis: On the one hand, a set of prominent Indian or diasporic writers accrues substantial literary capital through metropolitan review circuits and award systems and thus maintains the high international visibility that Indian writing in English has acquired ever since the early 1980s. Addressing a readership that spans countries and continents, this kind of writing functions as a viable tributary to world literature. On the other hand, a new boom of Indian mass fiction in English has emerged that, while targeting a strictly domestic audience, is always already implicated in the dynamics of world literature as well, albeit in a very different way: As they deploy, appropriate and adopt a wide range of globally available templates of popular genres, these texts have globality inscribed into their very textures even if they do not circulate internationally.

Freedom And Responsibility

Let me begin by admitting that I am wary of any comprehensive definition of consent. This bias stems from my professional concentration on criminal law, in which nouons of freedom and responsibility play vital roles in a wide range of contexts. In each context, however, one discovers that freedom means something different. A voluntary act is any bodily movement not caused by external force or nervous disorder. On the other hand, a voluntary act, however horrific its results, ordinarily may be punished only if the actor was subjectively aware that the act was wrong. In any event, a voluntary act may be excused as the product of duress if another person procures the actor's cooperation in the crime by an illegal threat that would overcome the resistance of a person of ordinary firmness.

CP solvers predominantly use arc consistency (AC) as the default propagation method. Many stronger consistencies, such as triangle consistencies (e.g. RPC and maxRPC) exist, but their use is limited despite results showing that they outperform AC on many problems. This is due to the intricacies involved in incorporating them into solvers. On the other hand, singleton consistencies such as SAC can be easily crafted into solvers but they are too expensive. We seek a balance between the efficiency of triangle consistencies and the ease of implementation of singleton ones. Using the recently proposed variant of SAC called Neighborhood SAC as basis, we propose a family of weaker singleton consistencies. We study them theoretically, comparing their pruning power to existing consistencies. We make a detailed experimental study using a very simple algorithm for their implementation. Results demonstrate that they outperform the existing propagation techniques, often by orders of magnitude, on a wide range of problems.
