The aim of this study is to investigate the feasibility of using waste bricks powder of Gachsaran Company in concrete. Cement is replaced by waste bricks powder in different proportions until 40 percent by weight. pozzolanic properties of bricks powder and compressive strength of concrete were investigated. The results demonstrated that the bricks powder show pozzolanic properties. Results also...

In this article we consider n gluon color ordered, planar amplitudes in N = 4 super Yang Mills at strong ’t Hooft coupling. These amplitudes are approximated by classical surfaces in AdS5 space. We compute the value of the amplitude for a particular kinematic configuration for a large number of gluons and find that the result disagrees with a recent guess for the exact value of the amplitude. O...

using of different systems of soil plough after changing unconsciously and non-scientific of land use, other soil physical and chemical characteristics affected. this fact, especially in marginal lands and mountainous regions is more visible. this research compared with the purpose of studying land use changing on some soil physical and chemical characters like very tiny sand percent, ph, ec, c...

Abstract The evaluation of the yield stability of genotypes and environment is of prime concern to plant breeders. Therefore, a comprehensive analysis of the structure of the GE interaction is needed. The objective of this investigation was to evaluate the use of sites regression (SREG) GGE methodology to stratify the pe × environment (GE) interaction in lentil. Yield data of 10 genotypes of le...

growth analysis is a valuable method in the study of quantitative of growth, development and crop production. in order to study the physiological growth indices of lentil plant under dry- farming conditions, an experiment was carried out as a randomized complete block design with three replications at the agricultural research station of lorestan university during 2010. in this experiment two c...

Three sections of Guri Member the Mishan Formation in Bandar Abbas area are investigated for foraminifera biozonation and lithostratigraphic correlation. The base conformably overlies Gachsaran (or Razak some sections), whereas top member is overlain by marls. Thirty-four foraminifer species identified prove age Burdigalian Gery Sheikh Anguran Burdigalian–Langhan range Bāz section. Two assembla...
