Abstract: The vibration of a cab deck as well as the mass of a deck supporting member is suppressed. A slewing frame of an upper slewing body includes a front plate connected to a second side plate. A cab deck is disposed on a front side of an engine deck with a gap between the cab deck and the engine deck. A deck supporting member is connected to the second side plate and the cab deck. When viewed along an up-and-down direction, a connection portion of the front plate to be connected to the second side plate is opposed to, in the lateral direction via the second side plate, a connection portion of the deck supporting member to be connected to the second side plate.

Abstract: The present invention is intended to provide a novel fluorescent labeled single-stranded nucleic acid, by which the background of an exciton oligomer can be further reduced and the novel use thereof. The present invention relates to a labeled single-stranded nucleic acid having at least two fluorescent atomic group pairs that exhibit an exciton effect. The labeled single-stranded nucleic acid is characterized in that the emission peak wavelength of one of the fluorescent atomic group pairs (fluorescent atomic group pair A) is shorter than the excitation peak wavelength of the other fluorescent atomic group pair (fluorescent atomic group pair B), and the fluorescent atomic group pairs A and B have a Förster resonance energy transfer (FRET) effect. This fluorescent labeled single-stranded nucleic acid is usable as a primer for amplifying a target nucleic acid or a probe to be hybridized with a target nucleic acid.

Abstract: The vibration of a cab deck as well as the mass of a deck supporting member is suppressed. A slewing frame 10 of an upper slewing body 1 includes a front plate 17 connected to a second side plate 15B. A cab deck 30 is disposed on a front side X1 of an engine deck 20 with a gap S between the cab deck 30 and the engine deck 20. A deck supporting member 40 is connected to the second side plate 15B and the cab deck 30. When viewed along an up-and-down direction Z, a connection portion of the front plate 17 to be connected to the second side plate 15B is opposed to, in the lateral direction Y via the second side plate 15B, a connection portion of the deck supporting member 40 to be connected to the second side plate 15B.

Abstract: The present invention provides a nucleic acid probe that can achieve high detection sensitivity and high specificity in mutation detection, mismatch detection, etc. by the PCR method, a method for designing such a nucleic acid probe, and a method for detecting a target sequence. The nucleic acid probe includes a nucleic acid molecule, and the nucleic acid molecule includes a plurality of fluorescent dye moieties that exhibit an excitonic effect. At least two of the fluorescent dye moieties that exhibit an excitonic effect are bound to the same base or two adjacent bases in the nucleic acid molecule with each fluorescent dye moiety being bound via a linker (a linking atom or a linking atomic group). The extension-side end of the nucleic acid molecule is chemically modified, thereby preventing an extension reaction of the nucleic acid molecule.
