Control Volumes

Diagnosis procedures primarily aim at locating the control volumes where anomalies occurred. This is not a simple task since the effects of anomalies generally propagate through the whole system and affect the behavior of several components. Some components may therefore present a reduced efficiency, although they are not sources of operation anomalies, due to nonflat efficiency curves. These induced effects are a big obstacle in the use of thermoeconomic techniques for the search of the origin of the anomalies. On the other hand, the real cause of the alteration of component behavior is the modification of its characteristic curve, due to degradation or failures. According to this concept, a new approach, based on an indicator measuring the alteration of the characteristic curve of the component affected by the operation anomaly, is proposed and applied to a test case power plant.

Islamic Jurisprudence

Muḥammad Saʻīd Al-‘Ashmāwī and Muḥammad Shaḥrūr are well known as contemporary Muslim thinkers. This article tries to map their contemporary ideas on Islamic jurisprudence. The main data of this research taken mainly from the works both of Al-‘Ashmāwī and Shaḥrūr. In particular, the paper tries to analyze Al-‘Ashmāwī‘s ideas on sharia, politics, hijab, marriage and divorce. On the other hand, the ideas of Shahrour on al-Qur'an, Sunnah and Fiqh, the theory of borders, pluralism, the commandment, inheritance, hijab, marriage, divorce, dowry, politics, and imamate are also critizised. After analyzing their lives and their ideas on Islamic jurisprudence, the paper found that their social, educational and practical backgrounds have affected their intellectual formations and ideas. Ashmawi is encouraged by diligence and enlightenment and is believed to be enlightened. Shahrour, however, takes a new approach in order to create the ḥudūd theory as a new way. As well as their intellectual background, Ashmawi has a good queen in Arabic, English and French as well as religion, Sharia, jurisprudence and theology. Shahrour is a good queen in Arabic, English, Russian, philosophy, philology and historical language.

It is well known that no rational number is approximable to order higher than 1. Roth [3] showed that an algebraic number is not approximable to order greater than 2. On the other hand it is easy to construct numbers, the Liouville numbers, which are approximable to any order (see [2], p. 162). We are led to the question, “Let Nn(α, β) denote the number of distinct rational points with denominators ≦ n contained in an interval (α, β). What is the behaviour of Nn(α, + 1/n) as α varies on the real line?” We shall prove that and that there are “compressions” and “rarefactions” of rational points on the real line.

Abstract Guigo II is commonly known and praised among specialists of Western mysticism for his Scala claustralium, a work that presents a spiritual program for cloistered monks. His Meditations, on the other hand, have usually been relegated to the margin of attention. The First Meditation, in particular, is generally regarded as a minor piece. The paper argues, however, that a new approach can make better sense of the First Meditation, while also enabling us to recognize its specific function and value. Seen from this new perspective, Guigo’s purpose with the text is to train and exercise his readers’ minds according to the spiritual program laid out in the Scala. The paper shows that the First Meditation realizes that goal, surprisingly, by having the same essential features that Umberto Eco found in the ‘open works’ of the Western avant-garde.

The book of Amos contains many undertones of threat, except in the epilogue which, according to many scholars, is redactional The question thus comes to the fore whether this characteristic implies that God is seen by Amos as a God of threat for whom one can only have fear. This article, however, points out Amos’ moral justification of God's deeds. Israel's actions, on the other hand, display a self-centredness and a lack of theocentric and personal approach. Within this framework the history of salvation, especially the exodus and the conquest of the land, as well as the election, covenant and the idea of the remnant, is fossilised and God is made a captive of space, time and relations. However, Amos' proclamation implies that in reality God cannot be made captive - neither of such a religion nor of a theology of threat. Amos envisions a situation in which everything will comply with the real aim set for it/him.

This paper is devoted to the consideration of the preconditions and results of the banking sector of Ukraine transforming, its influence on the sector’s productivity, stability and significance for the real economy. It’s grounded that banking sector of Ukraine has seriously weakened its potential for the economic development stimulation. On the one hand, due to the banking sector clearance from the bad and unscrupulous banks the system has become much more sensitive to the monetary instruments and its state is going to be more predictable and better controlled. But on the other hand, massive banks’ liquidations have caused the worsening of the confidence in financial system and radical increasing of the market concentration the highest degree of which is observed in the householders’ deposit market.

Real Essence

The purpose of the article is to conceptualize the philosophy of postmodernism that evolves, on one hand, as a search for new forms of creative self-expression, and, on the other hand, is presented as a crisis of philosophical cognition. The leading method for the study of postmodernism concepts is the systemic method allowing to determine their integrity and to explicate associative connections between them as interactions and interconnections brought into the system of the concept. Summarizing the discourse, we note that the main goal of postmodernism is to eliminate rational discourse and proclaim the end of the general metadiscourse of rationalism. Postmodernity should be seen as the transplantation of aesthetic matrices into surrogate, illusory, eclectic ones, which veiled the real essence of phenomena and processes.

So far, in social media, the hadith "ballighū 'annī walau āyah" has been widely misunderstood as a proposition for preaching even if it is only one verse. On the other hand, this hadith is also used as a suggestion for preaching without understanding the full meaning of a verse. This understanding is different from the real understanding, so a comprehensive discussion is needed to describe it. This article aims to identify misconceptions in understanding the hadith "ballighū 'annī walau āyah" on social media twitter and meet them with the correct meanings of the hadith. This study is a qualitative study which classify and analyze data by descriptive analysis. The discussion of this article explains how the hadith ballighū 'annī walau āyah is understood by Twitter netizens. The understanding of netizens is grouped into two categories, namely those that are appropriate and not in accordance with their real understanding. The factors that lead to misunderstanding of the hadith ballighū 'annī walau āyah are the insights of the hadith that are conveyed only a piece (not intact) and the dissemination of understanding through social media twitter with a short number of characters. This phenomenon causes a transformation of the hadith understanding in the form of degradation and distortion

The Cananéia (Upper Pleistocene) and the Comprida Island (Holocene) formations, outcropping in the Comprida island (SP) have been mapped using geomorphological and lithological criteria. Only one sample of the Cananéia Formation, collected in the homonymous island in front of the Comprida Island, was beyond the limit of the standard radiocarbon method. But since the publication of the geological map of the area in 1978, there has been some doubt on the real occurrence of Pleistocene deposits in southern extremity of Comprida Island. This paper deals with the results of thermoluminescence (TL) ages of eight samples from Comprida Island, which corroborate the Pleistocene age assumed during mapping surveys of these deposits. On the other hand, possible interpretations of the obtained ages, in relation to their depositional environments and related northern hemisphere Quaternary glaciations, are presented.

Regulated Firm

This article develops a simple model of a firm's privately optimal choice of the degree to which it will abide with regulations. The model allows for the firm to disguise its illegal actions in order to avoid detection and to expend resources to mitigate possible punishment for violations. Both price and quantity type regulatory schemes are considered. Under quantity regulation noncompliance increases the total amount of the regulated activity and distorts efficiency in production. Price regulation, on the other hand, introduces a kind of dichotomy between the real production plan of the firm and its illegal activity. Even though price regulations are substantially evaded, the total amount of the regulated activity remains unchanged, and the firm continues to produce efficiently.
