abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
islam spread rapidly after its founding, encompassing much of north africa, the middle east, and southeast asia. the art of this vast region draws its distinctive character both from islam itself and from the diverse cultural traditions of the world’s muslims. because islam discouraged the use of figurative images, particularly in religious contexts- unlike christian art- islamic artists develo...
u nderstanding t he e lements or s tructural c onstituents of t he m odern t heater is not e nough. it s hould be e xamined t hrough a m ethod according to which the characteristics of modern theater are harmonized and lead to an organized system. hence, the elements can only be understood through the whole body. this paper tries to achieve some results about the modern theater through a struct...
in this paper, we have tried to analyze and asses the process of formation and spatial – structural evolution of iranian-islamic cities through tehran case study as well as how to organize and effecting different factors specially modernism on urban elements. also we have discussed about formation and emergence of tehran and the effect of different pre modernism and postmodernism socio-economic...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
A lot of work has been devoted to the study of the magnetic interactions between two paramagnetic centres bridged by an aromatic ring.[1] The study of the spin delocalisation and polarisation effects is helpful in order to understand the nature of these magnetic interactions. The spin-polarisation mechanism itself provides a key tool for predicting the kind of magnetic interactions in high-spin...
