Author Information Genelyn G. Madjos  from the Institute of the  Department of Biological Sciences, College of Science and Mathematics, Western Mindanao State University, Zamboanga City, Philippines Journal Name Journal of Biodiversity and Environmental Sciences | JBES Abstract Nickel miningposed a serious environmental problem due to run-offs and tailings. To address this, current techniques include excavation, chemical stabilization and soil flushing, but these methods are costly and impractical. One of the ecologically accepted treatments is phytoremediation. With the capacity of Centella asiatica (gotu kola) to thrive in moist soils with domestic effluents, this present study sought to evaluate its phytoremediation potential by employing an experimental design with three replicates of: (a

Iron nanoparticles doped tea waste charcoal (Fe-TWC) was synthesized and characterized using powder XRD, SEM and EDX. Synthesized Fe-TWC was found quite effective in removing high concentrations of Ni (II) and Cr (VI) from the simulated samples as well as actual industrial samples. Adsorption data follows Langmuir adsorption and pseudo-second

Comparison of different solvents used in nanochloropsis algae oil extraction | INNS PUBNET | LinkedIn

Omid Rahmanpour1*, Hadi Ajami1, Ahmad Shariati1, Amir Hosseinzadeh Helaleh2 Gas Engineering Department, Petroleum University of Technology, Ahwaz, Iran Iranian Offshore Oil Company (IOOC), Siri, Iran In the past decades, the edible vegetable oil fuels were of no interest as a source of energy due to their higher price compared to fossil fuels. Recent increases in petroleum prices and confusions about the future petroleum availability have increased a renewed interest in vegetable oil fuels for diesel engines. There are large amounts of low-cost oils such as algal oils that could be converted into biodiesel. Microalgae have high potential for production of biodiesel. Thus transition to second generation biofuels, such as microalgae, can also contribute to a decrease in land needs due to their presumed higher energy yields per hectare and non-requirement of agricultural land. This paper presents technological advances made in extraction of microalgae oil. Different s

The study area is situated in the foothills of Hindukush mountain range at 5 Km from KKH, at an elevation of 2000 to 5000 m with an area of 310 km². Six stands of Chilghoza Forest were selected randomly for the enumeration of data from different locations and aspects suing Point Center Quadrate Method. Stand densities of the six stands were 16.61, 12.168, 7.367, 7.163, 4.320,

Modeling the compression index for fine soils using an intelligent method

-

Seyed Mahmood Kashefipour, Mehdi Daryaee Hydraulic Structures Department, Water Sciences Engineering Faculty, Shahid Chamran University Ahwaz, Iran Construction of buildings and different structures leads to soil consolidation, hence, causes soil settlement. Soil settlement depends on numerous factors, for instance, pressure deformation, depletion of pore water, and so forth. One way to calculate soil settlement, is utilizing compression index, which is obtained through consolidation test. Obtaining this index through consolidation test is too time-consuming; thus, researchers have attempted to relate compression index to soil physical parameters such as plasticity limit, liquid limit, void ratio, and relative density, which all could be simply measured; therefore, there is great deal of empirical relations in this regard. In this study, the correlation coefficients between the physical characteristics of fine soil and compression index were investigated using the Artif

Vegetation diversity of dune slacks in Egypt

Mahmoud El-Sayed Ali  Department of Plant ecology and Range Management, Desert Research Center (DRC), Cairo,Egypt The present study intends to evaluate the dune slacks vegetation inside the sand dune ecosystem of Egypt. It represented by fives slacks in three different habitats: two brackish, two saline and one cultivated slacks in North Sinai. The density and cover of species were measured in 26 stands, 2X2 m2 each. The total number of their cover was 56 species. The richest habitat was the brackish slacks followed by cultivated and saline slacks respectively. By using two way indicator species analysis (TWINSPAN) it gives 12 groups as follow (5 cultivated groups, 4 brackish groups, and 3 saline groups). By using ordination methods CCA we found highly correlation between cultivated and brackish slacks and the fine soil particles silt and clay and the percentages of organic matters; and salinity, chlorides and sodium salts and the saline slacks.
