Ryuji Kunimatsu Guitar Arrangement on the Oblivion by Astor Piazzolla: A Critical Analysis

This study examined the characteristics of Kunimatsu’s guitar arrangements in Astor Piazzolla’s Oblivion by comparing aspects of musical form, melody, and harmony. As with other arrangements’ performances, the primary motif of Astor Piazzola’sOblivion melodic theme in Kunimatsu guitar arrangement has always been played differently from the original version. This performance phenomenon could responsibly risk blurring the identification of structural boundaries within its musical form. The purpose of this study is to prove the basic construction of Oblivion melody, including its form structure and rhythmic characteristics, by comparing Kunimatsu’s arrangements against the composer’s original score. This study uses musicological research methods. The approaches applied in studying this work are analytical, theoretical, and comparative. This study compares the two data to reveal the musical forms and the differences in the primary motive rhythmic characteristics. The results of this study are findings of the Oblivion musical forms in both publications and the differences in primary motives rhythmic patterns in both sources. The difference in musical form is impressive, possibly caused by the insertion of auxiliary members. As a result, Kunamitsu arrangement includes using the two-part song form, originally a three-part song form. With the revelation of the original melodic structure that is clear from the results of this study, the musicians who will present the Oblivion will at least have the essential reference in their interpretation. This research contributes to expanding studies in classical guitar performance and musical forms and new approaches in textual musicological analysis that are still infrequent.

About grid generation in constructions bounded by the surfaces of revolution

For constructions bounded by the surfaces of revolution, structured grid generation technique is presented. Its technology has been elaborated within the variational approach for constructing optimal grids satisfying optimality criteria: closeness of grids to uniform ones, closeness of grids to orthogonal ones and adaptation to a given function. Grid generation has been designed for numerical solution of the differential equations modeling the vortex processes of multi-component hydrodynamics. In the technology, the three-dimensional construction in which it is required to construct a grid is represented in the form of the curvilinear hexahedron defining its configuration. The specific feature of the required configurations is that some faces of a curvilinear hexahedron lie in one plane and along edges of adjoining faces grid cells degenerate into prisms. Grid generation in the considered constructions has started to be developed by the elaboration of algorithms for the volume of revolution which has become the basic construction. The basic construction is obtained by the rotation through 180? around the axis of a generatrix consisting of straight line segments, arcs of circles and ellipses. Then the deformed volumes of revolutions are considered along with the generalizations of the volume of revolution which represent constructions obtained by the surfaces of revolution with parallel axis of rotation. The aim of the further development of the technology is to consider more and more complicated constructions and elaborate the technology for them. In the presentation, the current state of the development of the technology is given. Examples of generated grids are supplied.

The influence of envelopes in the thermal performance of residential buildings, from the perspective of bioclimatic architecture

Energy efficiency measures (EEMs) and their impact on the thermal performance of buildings as well as on the user's thermal comfort, have become the focus of several studies. Bioclimatic strategies can contribute to improving thermal performance while increasing indoor thermal comfort for users. This paper aims to verify the bioclimatic potential of two types of dwellings in three Brazilian cities. The first one is the baseline, with basic construction systems. The other includes EEMs. The method consists of the verification of bioclimatic potential by psychometric charts for indoor and outdoor conditions. The results show significant indoor discomfort caused by heat in both dwellings—thermal comfort conditions during more than 95% of annual hours in Manaus, and during 85% in São Paulo. Therefore, energy efficiency strategies such as shading, ventilation and HVAC systems are necessary to promote thermal comfort conditions in hot climates.

Arabic Lexical Phrases

The Arabic traditional grammar as well as Chomsky’s mainstream theory may not be able to provide a good analysis of some fixed Arabic phrases. The challenge of such data directly stems from the fact that the general syntactic rules assumed by the two opposing theories cannot explain the syntactic and the semantic aspects of the fixed Arabic data. I argue that the Construction Grammar provides an adequate account that does not rely on syntactic structure alone, as assumed by the mainstream theory or the Arabic traditional grammar, but rather it links phonological, syntactic, and semantic information together in one basic construction by means of some correspondence rules. The Arabic data proves that there is a strong need for a linguistic theory that takes into consideration all data of different range of productivity.

Motzkin algebras and the An tensor categories of bimodules

We discuss the structure of the Motzkin algebra [Formula: see text] by introducing a sequence of idempotents and the basic construction. We show that [Formula: see text] admits a factor trace if and only if [Formula: see text] and the higher commutants of these factors depend on [Formula: see text]. Then a family of irreducible bimodules over these factors is constructed. A tensor category with [Formula: see text] fusion rule is obtained from these bimodules.

Evolutionary morphology of the antennal heart in stick and leaf insects (Phasmatodea) and webspinners (Embioptera) (Insecta: Eukinolabia)

The morphology of the antennal hearts in the head of Phasmatodea and Embioptera was investigated with particular reference to phylogenetically relevant key taxa. The antennal circulatory organs of all examined species have the same basic construction: they consist of antennal vessels that are connected to ampullae located in the head near the antenna base. The ampullae are pulsatile due to associated muscles, but the points of attachment differ between the species studied. All examined Phasmatodea species have a Musculus (M.) interampullaris which extends between the two ampullae plus a M. ampulloaorticus that runs from the ampullae to the anterior end of the aorta; upon contraction, all these muscles dilate the lumina of both ampullae at the same time. In Embioptera, only the australembiid Metoligotoma has an M. interampullaris. All other studied webspinners instead have a M. ampullofrontalis which extends between the ampullae and the frontal region of the head capsule; these species do not have M. ampulloaorticus. Outgroup comparison indicates that an antennal heart with a M. interampullaris is the plesiomorphic character state among Embioptera and the likely ground pattern of the taxon Eukinolabia. Antennal hearts with a M. ampullofrontalis represent a derived condition that occurs among insects only in some embiopterans. These findings help to further clarify the controversially discussed internal phylogeny of webspinners by supporting the view that Australembiidae are the sister group of the remaining Embioptera.

LOCKING SYSTEMS IN BULGARIAN LANDS IN THE 16- 19 CENTURIES

В статье исследуются замковые системы на болгарских землях XVI - XIX вв. Замки рассматриваемого периода в основном изготавливались из кованого железа и отличались главным образом своим декором. Несмотря на свою уникальность, они представляют собой всего один базовый тип -замок с поворотным ключом. Существует несколько разновидностей этого замка, но их основная конструкция оставалась неизменной на протяжении веков. Модель была широко распространена в болгарских землях, замки этого типа предпочитали из-за простоты, надёжности и прочности. Из-за их относительно высокой цены очень немногие люди могли себе их позволить, и поэтому сохранившихся экземпляров этого периода не так много. Чаще всего их использовали для запирания общественных зданий, церквей, а также домов самых богатых купцов. Дешёвый импорт замков промышленного производства и навесных замков, импортированных из Западной Европы, которые широко использовались в конце XIX в., привёл к отказу от традиционных металлических замков ручной работы. The present article researches the locking systems in Bulgarian lands during 16-19 centuries. The locks during the considered period are mainly made of wrought iron and are distinguished mainly by their decoration. Despite their uniqueness, they are just one basic type - a rotary key lock. Several varieties of this lock exist, but their basic construction remains unchanged over the centuries. The model is widespread in the Bulgarian lands. It is preferred for its simplicity and reliability. The main requirement for the locks of this period is their physical strength. Therefore, they are always made of solid wrought iron. Due to their relatively high price, very few people could afford them and therefore there are not many preserved specimens from this period. Most often they are used to lock up public buildings, churches, as well as wealthiest merchants’ houses. The cheap imports of industrially produced locks and padlocks imported from Western Europe -which were widely used at the end of the 19 century - led to the abandonment of traditionally hand-made metal locks.
