The study of plant under environmental conditions leads to an appreciation of their physical and chemical requirements for growth and reproduction. It contributes to increase the knowledge of where the plants grow. This study was conducted to determine the main autecological characteristics of Salvia hydrangea L. which is an endemic plant distributed in Mazanadarn province, Iran. The habitats o...

The effect of environmental factors on plant vegetation is different. Therefore, it is necessary to evaluate role of these factors in medicinal plants growth, development and essential oil. This study was performed to investigate the effect of factors on qualitative and quantitative variations of the essential oil of Verbascum songaricum in its habitats in central Zagros Mountains, Iran in 2012...

In the SPEEDD project, we are developing approaches to the design and evaluation of Visual Analytics which are informed by Human Factors theories and methods. As part of this process, we are using the concept of Allocation of Function to inform the design of User Interfaces for Visual Analytics. The paper presents a case study of the development of a Road Traffic Management User Interface. ACM ...

This study aimed to assess ecological quality status of hard substratum macroinvertebrates communities of the Caspian Sea with three ecological indices and their relationship with environmental factors. For this purpose, benthic communities of the Caspian Sea basin were studied seasonally during 2014 in 8 sampling sites. Temperature, salinity, dissolved oxygen, pH, nitrate, nitrite, silicate an...
