(R)-Harmonine was synthesised in 15 % overall yield via a six-step sequence exploiting a Z-selective cross-metathesis reaction as its centrepiece. By this strategy, the cis-olefin present in the target could be installed exclusively. The use of an alcohol and an ester as the amine precursors was crucial for isolating the cross-metathesis product from the self-metathesis products. This method was also used to prepare two novel analogues of harmonine.

Sentiment analysis is the pre-eminent technology to extract the relevant information from the data domain. In this paper cross domain sentimental classification approach Cross_BOMEST is proposed. Proposed approach will extract <strong>†</strong>ve words using existing BOMEST technique, with the help of Ms Word Introp, Cross_BOMEST determines <strong>†</strong>ve words and replaces all its synonyms to escalate the polarity and blends two different domains and detects all the self-sufficient words. Proposed Algorithm is executed on Amazon datasets where two different domains are trained to analyze sentiments of the reviews of the other remaining domain. Proposed approach contributes propitious results in the cross domain analysis and accuracy of 92 % is obtained. Precision and Recall of BOMEST is improved by 16% and 7% respectively by the Cross_BOMEST.

During the First World War, many soldiers in the Belgian Army were endowed with a decoration, in order to inspire, motivate, and reward desirable conduct. The relationship between decorations and the soldier’s self-consciousness, his behaviour and his emotions, is present in every aspect of decorating, as it emphasized his self-esteem, pride, and character. By analysing the material aspects of decorations, the ceremonies surrounding their bestowal, and the textual motivation for doing so, this article explores the functions and effects of decorating, the evaluation of behaviour and self-conscious emotions by both Army Command and soldiers.

The cross sections for the self-reaction of state-selected HCl+ (DCl+) ions with HCl are shown to depend characteristically on the rotational velocity of the ion relative to that of the neutral.

A computational investigation is conducted to study the patterns of airflow induced by corona discharge in the cross section of a circular tube. The secondary flow induced by corona wind in various flow passages has been the subject of numerous investigations. The flow patterns are often identified by multiple recirculation bubbles. Such flow patterns have also been anticipated for circular cross sections where the corona discharge is activated by an electrode situated at the center of the cross section. In this investigation, it is shown that, contrary to public perception, a symmetric corona discharge does not generate a secondary flow in circular cross sections. This investigation then proceeds to demonstrate that the flow responsible for thermal enhancements in circular tubes often reported in the published literature is induced only when there is a slight asymmetry in the position of the electrode. The present computations are performed in two parts. In part one, the electric field equations are solved using the method of characteristics. In part two, the flow equations are solved using a finite-volume method. It is shown that the method of characteristics effectively eliminates the dispersion errors observed in other numerical solutions. The present computations show that the flow in the eccentric configuration is characterized by a corona jet that is oriented along the eccentricity direction and two recirculation zones situated on either sides of the jet. In addition to the computational approach, a number of analytical solutions are presented and compared with the computational results.

The approximate current distribution with height in vertical tower antennae of non-uniform cross section is calculated by assuming that the cross section is that of a cylinder whose diameter changes discontinuously. The field strength distribution in the vertical plane is then calculated for this current distribution and compared with field measurements of Ballantine. This is repeated using the experimentally determined current distribution of Gihring and Brown which results in a much closer check with Ballantine's measurements.The results were then used to calculate the field strength distribution in the vertical plane of an array comprising a 0.597λ vertical double-tapered tower as radiator, and a 0.250λ vertical tower of the self-supporting type as a fed reflector.


Oles Ulianenko, one of the most talented and controversial Ukrainian writers of these days, has been dead for ten years. His literary works did not receive any appropriate professional evaluation though because literary scholars and critics applied either the wrong or unproductive research methodology due to some objective and subjective reasons. The aim of the article is to suggest an alternative, in comparison to traditional variants, theoretical literary analysis which is grounded on the principles of the corporal-mimetic method to interpret fiction done on the extremely controversial novel “The Cross on Saturn” by O. Ulianenko. Having analyzed the idea and artistic content of the novel “The Cross on Saturn”, the conclusion is made that, first, the book characters seem to function as simulacra of their shallowness because they lack the depth of inner world. But despite this fact, despite parody, superficial dialogues and surrogate actions, the main characters of the novel and the peripeteia, they find themselves in, do not lose aesthetic appeal because these characters do not need deep inner world since their function is not determined by what these trivial characters reflect in the text mirror but by what the text mirror reflects in them. Second, the shallowness is filled with the content conditioned by the incest precedent which provides the basis of Oles Ulianenko’s novel to the degree to what the writer creates the tragedy in its exact, namely ancient Geek, meaning of the notion according to which tragedy is, on the one hand, a story determined by an utterly artificial form and content and, on the other hand, it is a story which does not simply end by death, it is a story which cannot end by anything else but death. It seems as if nothing but tragedy could make it impossible for a man to have their animal essence to supersede their human part.

This book examines the distinctive account of desire developed in the writings of the Spanish Discalced Carmelite friar John of the Cross (1542–1591), and locates its vital significance for modern depictions of Christian life and the transformation of the self. It contends that John’s delineation of the changes that are undergone by the ‘soul’ in the spiritual ascent is rooted in a distinctive, systematic, and neglected theological vision. A rich notion of desire animates his poetry and prose works and draws with creativity and novelty on biblical, Platonic, and Christian sources. This book traces the crucial role played by this underlying erotic driver of the spiritual ascent, and suggests that it represents a unique working out of the scholastic narrative of the graced transformation of the sensory appetites and the faculties of intellect, memory, and will. This is a neglected vision of the transformation of the self through the progressive purification of desire, which has the potential to significantly enrich current theological interest in desire and the self.

Abstract It is shown that the concurrence of the results obtained by varying the self coupling energy, the total second order energy and the cross coupling energy independently can be readily accomplished. In addition, it is possible to arrange to obtain any pre-specified value for the coupling constant. On this basis it is suggested that it might be dangerous to construe the concurrence of calculated results as an indication of convergence in practice.
