Title: Air conditioner and address setting method in air conditioner
Inventor: SUMIDA HISASHI
IPC: F24F11/02
Filed: 2007-03-07
Granted: 2015-11-26
Abstract: An air conditioner is provided with the features that address setting time is shortened and the address setting is accurately carried out. A serial number detecting unit (11a) transmits a first digit detecting instruction to a plurality of indoor devices (21-24) with multiple addressing and, when there is no response to the detecting instruction, the serial number detecting unit (11a) transmits an instruction to request a second digit, one digit before the first digit, to a plurality of indoor devices (21-24) with multiple addressing. That is, without returning to the original digit of the serial number, the address setting is redone from its one previous digit, so that address setting can be shortened. Further, when the address setting is carried out from the one previous digit and if a method for recognizing detecting instructions in the indoor devices (21-24) is changed, the address setting can be done more accurately.

Title: Using size and number aberrations in plasma DNA for detecting cancer
Inventor: LO YUK-MING DENNIS
IPC: C12Q1/68
Filed: 2020-10-30
Granted: 2024-01-11
Abstract: Analysis of tumor-derived circulating cell-free DNA opens up new possibilities for 
performing liquid biopsies for solid tumor assessment or cancer screening. However, many 
aspects of the biological characteristics of tumor-derived cell-free DNA remain unclear.  
Regarding the size profile of plasma DNA molecules, some studies reported increased 
integrity of tumor-derived plasma DNA while others reported shorter tumor-derived plasma 
DNA molecules. We performed an analysis of the size profiles of plasma DNA in patients 
with cancer using massively parallel sequencing at single base resolution and in a 
genomewide manner. Tumor-derived plasma DNA molecules were further identified using 
chromosome arm-level z-score analysis (CAZA). We showed that populations of aberrantly 
short and long DNA molecules co-existed in the plasma of patients with cancer. The short 
ones preferentially carried the tumor-associated copy number aberrations. These results show 
the ability to use plasma DNA as a molecular diagnostic tool.

Abstract: FIELD: lubrication fluid. SUBSTANCE: invention relates to reusing wastes in the form of slimes originating from metallurgical and mechanical engineering enterprises, in particular regenerating their water phase in the form of clarified emulsion remaining after primary oil recovery. Exhausted lubrication fluid is first settled to separate clarified emulsion from oil. pH value of emulsion is adjusted to 5.6-8.0 at heating to 70-100 C accompanied by turbulent stirring, after which emulsion is treated with aluminum chloride aqueous solution taken in specified amount and then with complete specified amount of solution of cationic flocculant: product of polymerization of dimethyldiallylammonium chloride with molecular weight 536000-600000. Introduction time for polymerization product is determined visually after registration of first pulsations on the surface of clarified emulsion caused by agitation. In the third step, anionic flocculant is also added in the form of 0.3-1% aqueous solution of polyacrylamide hydrolyzed in alkaline medium (molecular weight 500000-600000) and containing 10% of acid units of formula -CH 2 -CH(COONa)- and 90% of amide units of formula CH 2 CH(CONH 2 )-. Time gap between additions of the above-mentioned polymerization product and anionic flocculant is specified to be 40-60 min in absence of stirring. After addition of anionic flocculant, turbulent stirring is resumed for 1-3 min and degree of turbulization is strongly weakened until pulsations on the surface of emulsion are no longer visible and then emulsion is stabilized to terminate third step and settled for 60-70 min. Oil is once more recovered and, to separated emulsion, calcium oxide is added to reach pH 8.5 by reaction lasting during 40-60 min, after which emulsion is settled. Weight ratio of clarified emulsion to aluminum chloride, cationic flocculant, anionic flocculant, calcium oxide, and water is 1000000: (300-400): (25-50): (5-10): (500- 600): (15-20), respectively.
