The Song of Solomon is a series of love poems which contain 6 pieces of love poems and most part in the form of songs addressed by a man to a woman, and by the woman to the man, in order to express the love between them.Figures of speech are ways of making our language figurative. They can be divided into three parts, they are syntactical, semantic and phonetic rhetorical devices. These rhetorical devices can help us to heighten effect and to make the writing figuratively and vividly.These figures of speech used in the Song of Solomon make great contribution to the success description of these long songs.This essay will center on the figures of speech in the Song of Solomon. 展开更多

In this paper, linguistic methodology is suggested for approaching figures of speech formed due to shift of cognitive relations. First, requisite features, possible features and impossible features are proposed on the basis of semantic analysis and their interrelationships and expressions are discussed. Then it is further argued that all figures formed due to shift of cognitive relation are expressed to accept an impossible feature; and there are four semantic forms to accept it: “zero distance/distanced”, “implicit/explicit”, “direct/indirect”, “positive/negative”. Finally, starting from the two approaches to figures we comment on the traditional idea of separating decoration and substance and the new idea of “function as form”. 展开更多

Proliferative activity in 106 cases of non-Hodgkin’s lymphoma was estimated using the monoclonal antibody Ki67 and by counting the number of mitotic figures. The percentage of Ki67-positive cells was compared with the median number of mitotic figures per square millimeter. Both Ki67 positivity and the number of mitotic figures were found to be greater in high grade than in low grade lymphomas, although there was an overlap between the two grades of malignancy. A close correlation was found between the number of mitotic figures and the percentage of Ki67-positive cells not only in all lymphoma typo taken together (r_s= 0. 834 . P<0. 001). but also in B-cell lymphoma (r_s= 0. 8 1 P< 0. 001) and T-cell lymphoma (r_s = 0. 764. P<0. 00 1) taken seprately. Thus, both methods are useful for the estimation of proliferative activity. but each method has its advantages and disadvantages. 展开更多

In this paper,we will focus on consumers of Chinese products,but also other key players in this revolution of Chinese products in Ivory Coast:Ivorian traders,paying particular attention to the micro-social consequences of the arrival of Chinese products on the daily lives of Ivorian people.To date,work on relations between China and Africa is still struggling to grasp the micro-social consequences of Sino-African trade in African economies.Most of this work perceives Sino-African trade in terms of threats or opportunities for the development of African economies.While attention is generally focused on Chinese imports from Africa,given their geostrategic value,we want to show,in the case of Ivory Coast,the profound transformations induced by imports of Chinese products into Ivorian society.Sino-Ivorian trade has grown rapidly in recent years.While in 2012,exports of Ivorian products by China were 55,515 billion francs CFA(Communautéfinancière d'Afrique);in 2016,they reached 42,3831 billion francs CFA,On the other hand,imports from China increased by a whopping 364,103 billion francs CFA in 2012,reaching 885,699 billion francs CFA in 2016.This increase in imports of Chinese products by Ivory Coast corresponds to the arrival of a wide variety of manufactured products in the Ivorian market.For many Ivorians,the presence of these products on the Ivorian market is an expression of good Sino-Ivorian cooperation.In order to appreciate the various dimensions of Chinese products in Ivorian territory,our communication will be part of an interdisciplinary approach and will be based on empirical observations and interviews conducted in Ivory Coast during 2014-2016. 展开更多

The present paper has mainly the aim to formulate a quantum neurological model of brain dynamics during perception and cognition of ambiguous figures here including the case of the Dalmatian dog. First of all, we summarize our previous experimental and theoretical studies, evidencing as the basic conceptual foundations of quantum mechanics enter in a decisive manner in explaining the basic functions of brain dynamics at perceptive and cognitive level and at the level of our consciousness. This is done in detail in Sections 2 and 3 where we discuss also the role of the so called quantum interference effect and we include here the results of an our recent experiment confirming the role of quantum theory and of its quantum interference effect also at perceptive-cognitive and awareness levels. In Section 4, following our previous study, we consider the so called Mach-Zehnder interferometer. It is a physical device that is employed in quantum mechanical experiments in order to analyze such quantum interference effect. Soon after the discussion of this device, we proceed with the elaboration of a detailed quantum neurological model in the sense that we consider the brain regions identified in V1;V2/V3/V4 and A20 and we obtain that they may behave just as the beam splitters involved in the Mach-Zehnder quantum mechanical interferometer. In this manner, we formulate a model of V1;V2/V3/V4, A20 brain dynamics as a Mach-Zehnder interferometer and such model delineates a proposed neurological mechanism explaining perception-cognition and awareness in humans under the input of ambiguous figures and in the particular case of the Dalmatian dog. 展开更多
