Spatial configuration of deoxyribotrinucleoside diphosphates in aqueous solution.

The Morphology of Qom; The Study on Spatial Configuration Changes of The City (1956-2021)

The present study attempts to investigate the relationship between spatial configuration changes of Qom and the central core in the last half century. The main objective of this study is to review the Spatial form of Qom, and analyze the effect of changes in Urban configuration on the central core of the city and the main axes of urban activities during 1946 to 2011 and ultimately, Forecast the...

روابط بین «ویژگی‌های شناختی» و «پیکره‌بندی فضایی» محیط مصنوع، تجربه‌ای در دزفول

In an urban built environment, on the one hand people behave based on their spatial cognition of the environment spatial behavior in interaction with the environment depends on the spatial cognition. On the other hand many researches have also pointed that spatial configuration as the relational characteristics of the physical elements of environment, influence on the spatial cognition. Based o...

Visual Preferences of Small Urban Parks Based on Spatial Configuration of Place

The importance of small urban parks (SUP) in mega cities has been accepted as an essential component of urban lung and restorative settings. As urban population in the world increases and the cost of maintaining large parks escalates, urban authorities are shifting their attention to creating and maintaining smaller urban parks. However, SUP may present a different ambience due to their locatio...

Crime Prevention in Urban Design: towards Space Syntax Approach as a Quantitative Analytic Modeling of Qualitative Issue of Security (Based on Spatial Configuration)

Isoprenylation of Polyphenols in Aqueous Acid Solutions

Matract-Polyphenok condens with 2-methylbut-3cne-2-d or y,ydimethylallyl alcohol in 5% aqueous citric acid solution to yield phenolic 2Jdimethylchromans These facik condensation provide chemical support for the biogenetic theory of C-isopentenylation of phenols by 7,7dimcthylallyl pyrophosphate. Iso-psoralidin (20) has been synthesized from 7-hydroxy-2Jdimethylchroman (12) by a novel and conven...
