one of the main factors of premature deterioration of concrete structures is the corrosion of reinforcements. chloride penetration of concrete is one of the main reasons of this phenomenon. therefore, to have durable structure, it is necessary to have concretes with low permeability.there are various methods to evaluate permeability of concrete. finding a relationship between them can be useful...
The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...
LIFE+ project “Strategies to improve and protect soil quality from the disposal of olive oil mills’ wastes (OOMW) in the Mediterranean-PROSODOL” aims towards the development and application of technologies for the protection, improvement and remediation of soils which are polluted from the disposal of olive oil mill's wastes. In this effort, several geospatial application tools were presented a...
In this study, the effect of Ti substitution on structural and electrical properties of La0.8Sr0.2Mn1-xTixO3 (0 ≤ x≤ 0.075) compounds have been investigated. The double exchange interaction mechanism weakens by substituting the nonmagnetic Ti4+ ions in Mn4+ and Mn3+ sites. The results show that with increasing the doping level, metal-insulator transition temperature shifts to lower temperatures...
