Evaluation of Soil Physical and Chemical Properties in Poplar Plantations in North of Iran
Ali Salehi,Maryam Maleki
Ecologia Balkanica , 2012,
Abstract: Soil physical and chemical properties and some quantitative characteristics of Populus deltoides Marsh (clone 79.51) plantations and relationships between them were evaluated in Guilan plain of north of Iran. Two same aged poplar plantations with low and high qualities were selected. In each poplar plantation, fifteen sample plots with systematic sampling method were selected. In each sample plot diameter at breast height (DBH) as well as height of all trees within them was determined. Soil samples were taken from 0-20cm in each plot and soil texture, water holding capacity (WHC), bulk density (B.D) and particle density (P.D) as well as soil porosity, O.C, N, available P and exchangeable K were determined for each soil sample in laboratory. Tree data and soil properties between two plantations were analysed using independent samples t-test (Student’s t test at p < 0.05). The results showed that among soil physical properties, percentage of clay, sand, B.D and WHC and amongst soil chemical properties O.C, N, available P and exchangeable K were significantly different between two plantations. Heavy textured soils with high B.D are undesirable for growing of populus deltoides in study area. The results also indicated that poor quality plantations has negative effect on soil nutrient and reduces its fertility. Reduction of nutrient availability had negative effects on quantity and quality of poplar trees.
The Evolutionary Development of Echocardiography
Majid Maleki,Maryam Esmaeilzadeh
Iranian Journal of Medical Sciences , 2012,
Abstract: Echocardiography is a non-invasive diagnostic technique which provides information on cardiac morphology, function, and hemodynamics. It is the most frequently used cardiovascular diagnostic test only after electrocardiography. In less than five decades, the evolution in this technique has made it the basic part of cardiovascular medicine. Herein, the evolution of various forms of echocardiography is briefly described.
Foucault’s Idea of Power in Shelley’s Mont Blanc
Nasser Maleki,Maryam Navidi
Cross-Cultural Communication , 2011, DOI: 10.3968/j.ccc.1923670020110703.420
Abstract: There is a dominating power in every society; a power which imposes its own ideology on the people. Termed as ‘discourse’ by Foucault, this postmodern ideology is what people have to follow to gain their identity. Consequently, people need to stay in line with the dominating power, so that they would achieve their personal goals, identity and become a part of the pyramid of power. This power is only subdued and controlled by a superior power, which can cause changes in the dominating ideology, termed ‘Archive’ by Foucault. It seems that the ideas of Foucault can transparently be applied to the poem Mont Blanc by the English Romantic poet Shelley. This article aims at foregrounding Foucault’s idea of power in Shelley’s Mont Blanc , which does not seem to have received a significant attention by the researchers. Key words: Power; Foucault; Shelley; Discourse; Archive Résumé Il y a un pouvoir dominant dans toute société, un pouvoir qui impose sa propre idéologie sur le peuple. Nommé comme discours de Foucault, cette idéologie postmoderne est ce que les gens ont à suivre pour obtenir leur identité. Par conséquent, les gens ont besoin de rester en ligne avec le pouvoir dominant, afin qu'ils atteignent leurs objectifs personnels, l'identité et devenir une partie de la pyramide du pouvoir. Ce pouvoir est seulement ma trisé et contr lé par une puissance supérieure, qui peut causer des changements dans l'idéologie dominante, appelée Archives par Foucault. Il semble que les idées de Foucault peut être appliqué de manière transparente pour le poème du Mont-Blanc par les Anglais Shelley poète romantique. Cet article vise à mettant en avant l'idée de Foucault du pouvoir dans Shelley du Mont-Blanc, qui ne semble pas avoir re u une attention significative par les chercheurs.

John Keats’s and Suhrab Sipihri’s Poems in the Light of Objective Correlative
Nasser Maleki,Maryam Navidi
Cross-Cultural Communication , 2011, DOI: 10.3968/j.ccc.1923670020110704.202
Abstract: What Eliot meant by objective correlative was the conversion of emotions, not through expression, but an outer correlative of inner feelings – this kind of evoking emotion in the preserver can transparently correspond with Keats’s theory of impersonality. For Keats, the process of poetic perception includes the poet’s sympathetic identification with natural objects during moments of intense observation when the poet loses himself into an object, experiencing the details of the object through heightened perceptions and intuiting qualities or realities of the object not otherwise perceived – an oft-cited example is Keats’s odes. Amazingly, this hypothesis about Keats’s theory of impersonality or simply objective correlative can be equated and aligned with the term called ‘abstraction’ and its prominent exponent, Suhrab Sipihri in Persian literature. Considering such a perspective in mind, the present study is to foreground the manifestation of the terms impersonality and abstraction or simply objective correlative in the poetical vocations of Keats and Sipihri who lived in two remote continents of the world: Asia and Europe. Key words: Objective Correlative; Abstraction; Eliot; Sipihri; Emotion; Perception
Manifestation of Shklovsky’s Defamiliarization and Derredian Différance in the Poetry of Keats and Sipihri
Nasser Maleki,Maryam Navidi
Studies in Literature and Language , 2011, DOI: 10.3968/j.sll.1923156320110301.315
Abstract: It seems that there is a demonstration of Shklovsky’s defamiliarization in some of Keats’s and Sipihri’s poems; in them they tried to avoid the traditional logics and conventional ways of looking at the world in order to make difference in the locus of their observations. Amazingly, the function of these differences or contrasts can transparently be equated and aligned to what Derrida asserted as différance or to differ and defer. However, these dualistic ways of looking at the world, pave the way for new artistic perceptions which are not revealed promptly, instead, challenge and penetrate the reader’s mind to discover them. Considering such a perspective in mind, this article is to foreground the manifestation of these terms in some of the poems by Keats and Sipihri which does not seem to have received a significant attention by the researchers. The authors of this paper believe that the essence or the motifs in most of the artistic works of these two poets respond to a dualistic notion which is – or might be – an ongoing process in literary criticism. Key words: Keats; Sipihri; Différance;Defamilirization; Contrast; Dualism
MRI Findings in Knee Trauma
Maryam Barzin,Iradj Maleki
Iranian Journal of Radiology , 2009,
Abstract: "nMRI is the examination of choice for the evaluation of knee trauma. The use of a surface coil and thin-section high resolution scanning techniques in multiple planes has enhanced the depiction of structural details. This article reviews the MRI appearance of the normal knee anatomy and the role of MRI in the evaluation of knee trauma. The suggested protocol for the imaging of traumatic knee is coronal, sagittal and axial fast spin echo. At least one fat suppression sequence should be performed to rescale the contrast range and increase the conspicuity of soft tissue edema, fluid collection and bone marrow edema. The sagittal plane is generally the most effective for reviewing the internal derangement of the knee. Coronal imaging is necessary for the evaluation of the medial and lateral collateral ligament complex and axial imaging depicts the patellofemoral joint best. A meniscal tear is identified by an intrameniscal signal which extends to the joint surface. Tears in the anterior cruciate, posterior cruciate and collateral ligaments are also depicted. In this article we also evaluate the MRI findings of 100 patients with knee trauma and report the incidence of injury to different parts of the joint. The most common findings are joint effusion, meniscal injury and ACL tear. Some interesting cases of knee injuries are also shown.
Foregrounding Achebe’s Things Fall Apart: A Postcolonial Study
Nasser Maleki,Maryam Navidi
Canadian Social Science , 2011, DOI: 10.3968/j.css.1923669720110706.078
Abstract: Chinua Achebe (1930- ) took to the writing of novels and short stories in order to instill socio-cultural and historical awareness among his readers which had a subtle under-pattern of great validity in changing the life condition and outlook of men and women with a modicum of consciousness and sensibility. He was very much concerned about the fate of a society moving inexorably toward thoroughgoing denigration and the self abasement, which accompanied it. It is in this context that Achebe cautioned his native readers to note that the restricted colonial livelihood was not enough. He held that urgent need was some form of Negritude among the colonized Africa. With this perspective in mind, in this article the treatment of Achebe’s Things Fall Apart, as a literary preserver of the African social-cultural and historical values, is undertaken to be examined. This article also argues that through this novel Achebe extrapolates the pride in the cultural and religious aspects of the African postcolonial heritage. Key words: Africa; Achebe; Negritude; Identity; Colonizers
Eliot’s Journey of the Magi: the Metaphoric Arabesque of Human Soul in Quest of Reality
Nasser Maleki,Maryam Navidi
Canadian Social Science , 2011, DOI: 10.3968/j.css.1923669620110705.057
Abstract: The present study is a new attempt to make a religious analysis of Eliot’s touchstone called Journey of the Magi. Thomas Stearns Eliot wrote Journey of the Magi during the Modernist Free Verse era which began in the 1920s and continues on to this day as a part of the Post-Modernist movement. Poems composed during the time period are best known for their originality that makes the critics to brood on them repeatedly. Apart from Eliot’s literary and critical vocations, his Journey of the Magi is of great significance; though the poem, on the surface, portrays the journey of the Magi to find the baby Jesus, the potential Messiah who will bring about redemption to the world, it serves as a metaphoric arabesque for the difficult experiences one has to face in the course of a human soul’s bid to take the religious ascent and crystallize its integration and travel in a spiritual pursuit of faith. This is how Eliot got deeply committed to religion in terms of poetic sensibility though, his critics labeled him as a heterogeneous innovator of postmodern literary form and language. With this hypothesis in mind, in this article the treatment of religious arabesque of the modern man in ascending spirituality and search for reality in the Eliot’s Journey of the Magi is undertaken to be examined. Key words: Religiosity; Quest; Reality; Magi; Soul; Journey Résumé La présente étude est une nouvelle tentative afin de faire une analyse religieuses de pierre de touche d'Eliot appelé Journey of the Magi. Thomas Stearns Eliot a écrit Voyage des Mages à l'époque Free Verse moderniste qui a commencé dans les années 1920 et continue à ce jour comme une partie du mouvement post-moderniste. Les Poèmes composés pendant la période de temps sont surtout connus pour leur originalité qui fait la critique à ruminer sur eux à plusieurs reprises. En dehors de vocations littéraires et critiques d'Eliot, son voyage des Rois Mages est de grande importance, bien que le poème, à la surface, dépeint le voyage des Rois Mages à trouver l'enfant Jésus, le Messie potentiel qui va apporter la rédemption au monde, il sert une arabesque métaphorique pour les expériences difficiles qu'on a à faire face au cours de la candidature de l'ame humaine de prendre l'ascension religieuse et cristallisent son intégration et de voyage dans une recherche spirituelle de la foi. Voilà comment Eliot s'est profondément attaché à la religion en termes de sensibilité poétique cependant, ses détracteurs lui étiqueté comme un innovateur hétérogène de la forme littéraire postmoderne et la langue.

On the rate of graded modules
Rasoul Ahangari Maleki,Maryam Jahangiri
Mathematics , 2014,
Abstract: Let $K$ be a field, $R$ a standard graded $K$-algebra and $M$ be a finitely generated graded $R$-module. The rate of $M$, $rate_R(M)$, is a measure of the growth of the shifts in the minimal graded free resolution of $M$. In this paper, we find upper bounds for this invariant. More precisely, let $(A,\mathfrak{n})$ be a regular local ring and $I\subseteq \mathfrak{n} ^t$ be an ideal of $A$, where $t\geq 2$. We prove that if $(B=A/I, \mathfrak{m} =\mathfrak{n} /I)$ is a Cohen-Macaulay local ring with multiplicity $e(B)= \binom{h+t-1}{h}$, where $h=embdim(B)-dim B$, then $rat(gr_{\mathfrak{m}}(B))=t-1$ and for every $B$-module $N$, which annihilated by a minimal reduction of $\mathfrak{m}$, $rate_{gr_{\mathfrak{m} }(B)}(gr_{\mathfrak{m} }(N))\leq t-1$.

Maryam Esmaeilzadeh,Majid Maleki,Fereidoun Noohi
The Cardiology , 2011,
Abstract: The purpose of this study was to quantitate the degree of left-to-right shunt in patients with 2°ASD by PISA method in comparison with continuity equation. The PISA method has been used extensively in patients with valvular regurgitation and stenosis for quantitative measurement of regurgitant severity and valve area. But its use in patients with left-to-right shunts including ASD has not been evaluated extensively. We studied 48 consecutive patients with 2° ASD (mean age: 32.5+-4 years; range: 18-54 years). Left-to-Right shunting was quantified by continuity equation and PISA methods. The defect size was between 12-40 mm (mean: 26+- 6). QP/QS by continuity equation was between 1.7-4.5/1 (mean: 2.91) and by PISA method was between 1.6-4.8/1 (mean: 2.92), [r = 0.92, PV= 0.0001]. There was no significant difference between the degree of shunt estimated by continuity equation and PISA method in terms of the defect size and the degree of shunt (PV = 0.179). The PISA method could be as an accurate alternative method of continuity equation for quantitation of the degree of shunt flow in patients with 2°ASD.
