Patent CA-2213709-A1 (CA)
Inventor: SORIANO THOMAS F
IPC: G01N33/573
Filed: 1996-02-21
Abstract: The present invention relates to novel methods for diagnosing benign prostatic diseases (BPD), such as benign prostatic hyperplasia, prostatitis, or glandular atrophy, in a male human patient without requiring a biopsy. The total prostate specific antigen (PSA) level in the blood or serum of the patient is measured. If the patient has a total PSA  level of between about 2,5 ng/ml and 10.0 ng/ml, then the free PSA level in the blood or serum of the patient is measured. The proportion of free PSA to total PSA is calculated. If this proportion is equal to or greater than about 25 %, then the patient is diagnosed as having BPD. Optionally, if the patient has a total PSA level of between 10.1 ng/ml and 20.0 ng/ml, then the free PSA level in the blood or serum of the patient can also be measured. The proportion of free PSA  to total PSA is calculated. If this proportion is equal to or greater than about 25 %, then the patient is diagnosed as having BPD.

Title: Novel method for the control of biodegradation
Inventor: HELMO KIM
IPC: C02F3/00
Filed: 1996-05-02
Abstract: A novel method for control of biodegradation is disclosed, said biodegradation being performed by mixed cultures of microorganisms. Measurements and adjustment (preferably on-line) of process parameters which relate to metabolic activity of the microorganisms are performed in such a manner that simultaneous nitrification and denitrification is effected in the same environment while keeping the oxygen concentration below 1 ppm. The method allows the use of high biomass concentrations (up to 20 kg/m3) and reduces energy consumption and process volume of e.g. activated sludge processes, thereby saving costs for waste water purification. Generally, the process ensures optimized conditions for microorganisms in the process. Also disclosed is a method for waste water purification and a waste water purification plant which both employ the method for control of biodegradation. Finally, a method for determining set-point values allowing the control is also disclosed.

Title: Process for the production of higher oxo alcohols
Inventor: GUBISCH DIETMAR
IPC: C07C29/141
Filed: 1997-12-22
Abstract: Disclosed is a process for the production of an oxo alcohol having 7 to 18 C atoms by hydroformylation of the corresponding olefin with synthesis gas in the presence of an organic phase containing a cobalt catalyst at 50 to 220°C and a pressure from 100 to 400 bar, and subsequent hydrogenation of the aldehydes. The cobalt catalyst is formed by reacting an aqueous cobalt salt solution in the presence of an organic solvent which is only slightly miscible with water or not at all, with synthesis gas, and the organic phase containing the cobalt catalyst is obtained by extraction of the cobalt catalyst formed from the aqueous phase by means of an organic extractant which is only slightly miscible with water or not at all. The formation of the cobalt catalyst, the extraction of the cobalt catalyst formed into the organic phase and the hydroformylation of the corresponding olefins are carried out in a single-stage process. The oxo alcohol produced may be used for the production of a carboxylic acid ester useful as plasticizer for plastics.
