Production of demineralised high quality hierarchical activated carbon from lignite and determination of adsorption performance using methylene blue and p-nitrophenol: The role of surface functionality, accessible pore size and surface area.

In the adsorption process, the surface area, pore and particle size distribution and the chemical structure of the solid and the type of adsorbent are of vital importance. Activated carbon (AC) is a very good adsorbent material and its cost is highly dependent on the starting material and production method. The pore size and functional structure of the surface depend on the amount of activation chemical used.

The performance of sulphur doped activated carbon supercapacitors prepared from waste tea.

The pore structure, high surface area and good conductivity are the key properties for the electrochemical double layer based supercapacitors. The activated carbons were produced from the waste tea, utilising microwave pretreatment with HPO and activation at 450°C. Sodium thiosulfate pentahydrate (NaSO·5HO) was used as sulphur doping agent at 800°C to enhance conductivity of the activated carbons.

Our urethrocutaneous fistula repair results in adults after hypospadias surgery.

Introduction: Our aim was to evaluate and share our urethrocutaneus fistula repair results in adult patients who had been operated for hypospadias in their childhood.

Material And Methods: The data of totally 48 patients who had been treated for urethrocutaneous fistula after hypospadias surgery in our department from May 2008 to January 2015 analyzed retrospectively. Patients' age at fistula repair, age at first hypospadias surgery, fistula size, localization and number, distal urethral obstruction status and surgical outcomes of fistula repairs were recorded.

Examination of gas and solid products during the preparation of activated carbon using phosphoric acid.

Activating agents play significant roles in the preparation of activated carbon (AC) from biomasses and their wastes, which are widely used in AC production. Application methods are also important for the production process. Products give remarkable ideas regarding the method and heat treatment process.

Does an asymmetric lobe in digital rectal examination include any risk for prostate cancer? results of 1495 biopsies.

Introduction: Despite the well-known findings related to malignity in DRE such as nodule and induration, asymmetry of prostatic lobes, seen relatively, were investigated in a few studies as a predictor of prostate cancer so that there is no universally expected conclusion about asymmetry. We aimed to compare cancer detection rate of normal, asymmetric or suspicious findings in DRE by using biopsy results.

Materials And Methods: Data of 1495 patients underwent prostate biopsy between 2006-2014 were searched retrospectively.

Renal metastasis from pancreatic adenocarcinoma: a rare case along with literature review.

Metastatic masses in the kidney are rare, and metastasis of pancreatic adenocarcinoma to the kidney is even rarer. A 58-year-old male patient with macroscopic hematuria presented to the emergency department. Abdominopelvic computed tomography revealed a lesion that was not visualized as a complete mass but instead appeared as a patch extending from the pelvis to the parenchyma.
