Pre-historic pottery investigating is one of the sources that provide a lot of information about the life and art of that time. Among Iranian arts, Pottery is of a greater antiquity, originality and importance and represents people’s culture, beliefs and traditions more than any other art. After basket weaving, pottery has been the first lasting art of mankind. By investigating earthenware moti...
In the present paper, trapped ion mobility spectrometry (TIMS) and theoretical calculations have been used to study carotenoid geometrical motifs generated by photoisomerization from the all-trans geometry. Multiple geometric isomers of the carotenoids lutein and zeaxanthin were separated using TIMS (R > 110) for [M](+), [M + H](+), and [M - 18](+) molecular species. Comparison of observed cros...
The Marashian government (Marashieh) had a Shia religion, they ruled from 760 to 906 AH in the Tabaristan region (now it is Mazandaran). During this period, the construction of mausoleums, shrines and elders of the Marashi government flourished. Unlike modern metal tombs most of them have wooden artifacts same as are in cenotaph mausoleum. These cenotaph mausoleums often have decorations with i...
One of the outcomes of the long wars in Afghanistan is the emergence of "war rugs". In this paper, the evolution of the war rugs in Afghanistan has been studied using a descriptive-analytical method and the data has been collected using field study and library-based research. The results of the research indicated that from the beginning to the present time, the war rugs in Afgha...
n this special issue, three papers belong to the path 1 , six papers o the path 2 , and two papers to the path 3 . The thermal path to generate electricity is referred as “concenrated solar power” or CSP. The greatly insolated “sunbelt” reions of the world include large Asian regions in China and India s well as the southwestern United States, southern Europe, Ausralia, the MENA regions, etc. T...

Hunting and animal’s combat design of animals in the Safavid era has been reflected in various compositions of carpet designs as they are combined with Floral, Medallion, and Corner and Medallion patterns. One of the significant examples of a hunting ground corner and Medallion carpet are the ones held in the Poldi Pezzoli Museum, Milan. In this carpet, hustling hunting scenes have been depicte...
graffiti as one of the social phenomenon has a very long record. however, the graffiti in modern civilization has been put forth as a media. in this article, efforts have been made to study the graffiti from the linguistic perspective. in this research, 2929 graffiti from different districts in the north, south, east, west and center of tehran have been registered and then extracted and analyze...
The crystal structure investigation of the title compound 4-((pyrrolidin-1-ylsulfonyl) methyl)aniline (PSMA) C11H16N2O2S shows that molecule is essentially coplanar with a dihedral angle 26.70(14)°between pyrrolidine and benzene rings. A pair strong N-H···O hydrogen bonds produces continuous two-dimensional sheets R22(18) ring motifs. also features weak C-H···π interaction resulting in three-di...
Geometric frustration is an approach to the glass transition based upon the consideration of locally favoured structures (LFS), which are geometric motifs which minimise the local free energy. Geometric frustration proposes that a transition to a crystalline state is frustrated because these LFS do not tile space. However, this concept is based on icosahedra which are not always the LFS for a g...
