Peanut shell biochar for Rhodamine B removal: Efficiency, desorption, and reusability.

A high-performance and affordable peanut shell-derived biochar was employed for the efficient removal of Rhodamine B (RhB) from aqueous solutions. The properties of peanut shell biochar (PSB) were investigated through Fourier transform infrared (FTIR) spectroscopy and Brunauer-Emmett-Teller surface area measurements. The FTIR analysis revealed numerous active sites and functional groups for the binding of dye molecules, while the BET surface area was determined to be 351.

Temperament and character properties of male psoriasis patients.

Personality properties have an effect on the onset and triggering of psoriasis. The current study aimed to examine the personality of psoriasis patients in relation to the severity of the illness. Psoriasis and healthy participants completed the Beck Depression Inventory, Beck Anxiety Inventory, Maudsley Obsessive Compulsive Inventory, Temperament and Character Inventory.

Heavy metal content and distribution in surface sediments of the Seyhan River, Turkey.

Chemical fractionation of seven heavy metals (Cd, Cr, Cu, Mn, Ni, Pb and Zn) was studied using a modified three-step sequential procedure to assess their impacts in the sediments of the Seyhan River, Turkey. Samples were collected from six representative stations in two campaigns in October 2009 and June 2010, which correspond to the wet and dry seasons, respectively. The total metal concentrations in the sediments demonstrated different distribution patterns at the various stations.

Stentless bioprosthesis provided excellent hemodynamic performance in a military scuba diver with infective endocarditis.

Infective endocarditis is a diagnostic and therapeutic challenge that ultimately requires surgical intervention in 20% of all cases. Surgical treatment of active infective endocarditis requires not only hemodynamic repair, but also special emphasis on the eradiation of the infectious focus to prevent recurrence. This goal can be achieved by the combination of aggressive debridement of infective tissue and appropriate and adequate antibiotic treatment.

Left anterior descending artery arising as a terminal extension of posterior descending artery (a rare coronary artery anomaly).

Several types of left anterior descending artery anomalies have been detected. In these anomalies, left anterior descending artery usually originates from the right coronary artery or right sinus of Valsalva. A case of left anterior descending artery arising as a terminal extension of posterior descending artery presented.

A comparison of the performance of mesophilic and thermophilic anaerobic filters treating papermill wastewater.

Two anaerobic filters, one mesophilic (35 degrees C) and one thermophilic (55 degrees C), were operated with a papermill wastewater at a series of organic loadings. The hydraulic retention time (HRT) ranged from 6 to 24 h with organic loading rates (OLR) 1.07-12.
