Polycyclic Aromatic Hydrocarbons Separation from Oil-Contaminated Soil Using Supercritical and Subcritical Water

Finding an environmental-friend and an affordable method to remove contaminated soils from polycyclic aromatic hydrocarbons (PAHs) is now an attractive field for researchers. PAHs are slightly soluble, thus hardly dissolve in organic compounds, and also biological and chemical degradation processes are not effective to remove them, and the process of extracting these pollutants from soil is a complex process. Super-critical fluid extraction is an innovative process in the field of contaminated soil treatment. Extraction with super-critical fluid is a simple and rapid extraction process which uses supercritical fluids as solvents. This method addresses extraction methods using supercritical and subcritical fluid. The results showed that the supercritical fluid process is very suitable to remove the pollutants such as PHCs, PAHs, PCBs, dioxins, Furans, phenols, Chlorophenols, insecticides, metals and radioactive substances. The supercritical fluid extraction using CO2 also has the ability to effectively eliminate organic and inorganic compounds present in different contaminated soils. Moreover, this method is more economical for polluted soil treatment compared to other available methods. On the other hand, using this method that uses water is environment-friendly and has lower cost and a higher safety level. Research has also shown that pressurized hot water extraction (SWE) is a better way to extract PAHs. In this method, the extraction process can be improved by combining the SWE process with the oxidation process by adding oxidants such as air, oxygen, hydrogen peroxide, etc.

On Similarity of Pressure Head and Bubble Pressure Fractal Dimensions for Characterizing Permo-Carboniferous Shajara Formation, Saudi Arabia

Pressure head was gained from the distribution of pores to characterize the sandstones of the Shajara reservoirs of the permo-Carboniferous Shajara Formation. The attained values of pressure head were employed to calculate the pressure head fractal dimension. Based on field observations in addition to the acquired values of the pressure head fractal dimension, the sandstones of Shajara reservoirs were divided here into three units. The obtained units from base to top are: Lower Shajara Pressure Head Fractal Dimension Unit, Middle Shajara Pressure Head Fractal Dimension Unit and Upper Shajara Pressure Head Fractal Dimension Unit.

Investigation of Graphene Oxide in Diesel Soot

NanotechnologyAbstractIntroductionGraphene has emerged as a potential material in various scientific disciplines, ranging from material science, engineering, and more recently biomedicine. The paper describes the investigation of the presence of graphene and graphene oxide (GO) in the carbon soot of internal combustion diesel engines. The UV-Visible, Fourier transform infrared (FTIR), X- ray diffraction (XRD), Photoluminescent (PL) and Raman spectroscopic analysis of the sample provided a conclusive evidence of the formation of graphene and GO. The Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive Spectrum (EDX) of the sample show carbon nanoparticles (CNPs) of size less than 50nm.

Assessment of Rumen Microbial Adaptation to Garlic Oil, Carvacrol and Thymol Using the Consecutive Batch Culture System

Although plant derivatives have shown promise in reducing enteric methane (CH4) emissions from ruminants in short-term studies, investigation on possible rumen microbial adaptation to these compounds is still limited. The objective of this study was to assess the possibility of mixed rumen microbial adaptation to antimethanogenic plant derivatives over relatively long-term in vitro incubation. Treatments were: garlic oil, carvacrol and thymol, each at a final concentration of 300 mg/l.

Video-Thoracoscopic Extended Thymectomy with Sternal Elevation and Carbon Dioxide Insufflation

To remove the thymus safely and completely in the surgical management for MG, especially for the upper pole of the thymus in the neck, we have performed video-thoracoscopic extended thymectomy (VATET) with sternal elevation and carbon dioxide (CO2) insufflation. From November 2013 to May 2014, we conducted VATET for three MG patients. Symptomatic improvement was obtained, and there was neither mortality nor perioperative complications. VATET with sternal elevation and CO2 insufflation was a safe and valid technique for thymectomy for MG. Clinical short-term results were satisfactory.

Targeted Approach for Prostate Cancer Treatment: Synthesis and Characterization of Docetaxel-Loaded Perfluorocarbon Nanodroplets

The purpose of this study is to synthesize and characterize nanodroplets, loaded with docetaxel for treatment of prostate cancer under MR-guided focused ultrasound. Water insoluble docetaxel encapsulated in nanodroplets is expected to be delivered into tumors with greater efficiency while minimizing drug related systemic toxicities when used in combination with focused ultrasound. The sequence of our studies toward development and characterization of docetaxel-loaded nanodroplets is as follows. First, we developed methods for synthesis of ultrasound-responsive, docetaxel-loaded nanodroplets (Doc-nd) by a solid dispersion technique. Secondly, we characterized Doc-nd by its morphology and size distributions using a dynamic light scattering (DLS) method.

Characteristic Human Scent Compounds Trapped on Natural and Synthetic Fabrics as analyzed by SPME-GC/MS

The collection of human odor volatiles is of interest to forensic applications as a path to investigate canine scent discriminations in legal investigations. A study using a selected array of previously identified human odor compounds has been conducted to determine the retention and release capabilities of five (5) natural and synthetic fabric types, cotton (mercerized fabric and gauze matrix), polyester, rayon and wool.
