DOES BITUMINOUS COAL CONTAIN ANY BITUMEN?

IGCC Technology — Bituminous Coal IGCC With and Without CCS

Six Integrated Gasifi cation Combined-Cycle (IGCC) power plant confi gurations operating on bituminous coal were evaluated and the results are presented in this summary sheet. All cases were analyzed on the same basis, using a consistent set of assumptions and analytical tools. Each gasifi er type was assessed with and without carbon capture and sequestration (CCS). The individual confi guratio...

Caenorhabditis elegans DNA does not contain 5-methylcytosine at any time during development or aging.

DNA, isolated from age-synchronous senescent populations of Caenorhabditis elegans has been quantitatively and qualitatively analyzed for the presence of 5-methylcytosine. High performance liquid chromatography on two wild-type and several mutant strains of C. elegans failed to detect any 5-methylcytosine. The restriction endonuclease isoschizomers, HpaII and MspI, were used to digest genomic D...

Does anterior prostatic fat tissue removed during robotic radical prostatectomy contain any lymph nodes?

INTRODUCTION We investigated whether anterior periprostatic fat (APPF) tissue removed during robotic radical prostatectomy (RARP) contains any lymph nodes (LNs). MATERIAL AND METHODS APPF tissues removed during RARP in 129 patients were evaluated histopathologically. Correlation with postoperative pathologic stage was made. Patients with a history of previous prostate or bladder surgery and r...

Does Propolis Contain Tannins?

Although polyphenols have been reported as common constituents of propolis, tannins have rarely been mentioned as its constituents. Propolis samples from seven localities in Brazil were analyzed for detection of proanthocyanidins (condensed tannins) and determination of the tannin content. Positive reaction for proanthocyanidins was observed for all samples tested. The contents of tannins varie...
