BACKGROUND Patents have been granted for a number of techniques for petroleum biodegradation including use of micro-organisms for degradation of hydrocarbon-based substances and for hydrocarbon degradation in oil reservoirs, but there is a dearth of information on hydrocarbon degradation in different soil textures. OBJECTIVE Hence, this work investigated the effects of different soil textures...

Mangroves in gulf of Kachchh, Gujarat, India has been studied for grain size spectrum and textural parameters namely phi mean, standard deviation, skewness and kurtosis. Grain size spectrum shows a marked variation in the upstream riverine input stretch. Variation of energy conditions is controlled by the fluvial profile in the channel. Textural pattern shows complicated profile as a result of ...

Background: Estrogens include estoril (E3), estradiol and estrone (E1). These chemicals are produced in human and animal bodies as well as in synthetic chemicals (drugs). Estrogens can enter water sources in different ways. When these chemicals enter the human body through water and wastewater, they have the ability to mimic or disrupt the normal estrogen activities in humans and animals. Estro...

This study aims to provide an alternative soil improvement that can be applied in the Petobo area, which experienced liquefaction on September 29, 2018. Ferronickel slag is utilized as a binding agent. Furthermore, large concentrations of alkaline solutions (potassium hydroxide and sodium hydroxide) are activators activate kaolin initiate geopolymer production process. From test results, it con...

Investigating the soil-water characteristics of calcareous soil has a great significance for preventing geological disasters on island-reefs as well maintaining foundation stability hydraulic-filled island-reefs. In this study, silty sands with different fines contents and dry densities were studied to reveal their effects The characteristic curve (SWCC) sand was measured using pressure plate a...
