Using Microcontroller Based Digital Portable Soil Testing Device (“Matir Pran”) for Agricultural Sector Development (Published)
The major economic sector in Bangladesh is agriculture, which contributes 19.6% of the nation’s GDP and employs 63% of the residents. The agricultural products feature like growth, quality dependent on the soil condition. Now a day’s most of the farmer’s family in Bangladesh uses smart phone. Based on this availability of smart devices and huge potentiality of uses of the devices, this project and study have been done for finding the common most useful two features of soil like measuring the pH level and testing the moisture of soil instantly, which usually reported after a long-time traditional process of analysis. These android-based apps incorporated in the smart device, which help the farmer to plant crops based on the testing parameters – pH level and moisture displayed in the screen of the devices. After testing android apps suggests the farmers- which types crops they can plant in this field, it can also suggest the way of increasing and decreasing the pH level. Arduino Nano, OLED display, pH sensor, moisture sensor are the main hardware and XML, material design (for front end) and JAVA, SQLite database, (for back end) are the software uses in the project.

Hydrocarbon Soil Treatment Test with Sodium Dodecyl Sulfate (SDS) (Published)
The depollution test was carried out through the surfactant washing process. The effects of variation in SDS concentration (0.5-1 g/L), contact time (10-60 min) and soil particle size (<50 μm – <250 μm) were studied on the efficiency of depollution through a complete factorial plan. Quantitative analyzes performed on the different fractions of a soil sample showed that the fine fraction (<50μm) is the most polluted. In fact, the contents of n-alkanes in soil particles of sizes <50 μm range from 4.79 to 65.90 μg/g of sample MS and in sizes of <250 μm, from 0.91 to 30 μm, 70 μg/g of MS. PAH contents in fractions <50μm range from 3.46 to 103.5 μg/g of sample MS and in fractions <250 μm, from 2.90 μg/g to 21.85 μg/g of MS. These hydrocarbon levels obtained are much higher than the guide values defined by the French Environment and Energy Management Agency. The application of this washing process has made it possible to achieve overall hydrocarbon abatement rates of up to 97.3%. As a result, the optimum for the minimum content of residual hydrocarbons (≈10 μg/g DM) is obtained at a concentration of 0.75 g/L, a contact time of 60 min and a particle size of soil < 50 μm. This process, which makes it possible to obtain an interesting yield of extraction of pollutants, could thus be used for the remediation of soils and sediments polluted by hydrocarbons in general and PAHs in particular.

The Role of Soil and Land Features of Iran Native Architecture &Energy Management and Sustainability (Published)
Today, management of consumption energy is important for architecture. Traditional buildings in Iran have employed some ingenious passive techniques especially in hot regions in order to restore thermal comfort and coordinate with the local environment and climate. Architecture soil is ancient Iranian architecture and the use of soil qualities such as high thermal capacity and thermal 7-hour delay in the management of energy consumption and achieves sustainable architecture and green. In this research, study native architecture in order to introducing appropriate solution for achieving sustainability. The methodology of this study is descriptive –analytic and collecting data is done by documents-library.at finally, has been proposed strategies in about mention method in order to achieving sustainable architecture in Iran.
