The blockable bone plate consists of a plurality of plate members which are connected to each other via webs. A screw hole is provided in at least some plate members, preferably in each plate member. The screw hole is surrounded by a spherical countersink on the upper surface of the plate. Provided internally in the screw hole there is an engagement contour which consists of contour valleys and contour peaks partially running in a horizontal and radial peripheral direction on the wall of the screw hole. The engagement contour is preferably produced by milling and has for example a pointed, round, trapezoidal or serrated configuration. A blocking thread is provided under the screw head of the screw intended for blocking. As the screw is screwed in, the blocking thread engages in the engagement contour. The particular advantages lie in increased security against the screw coming loose and in the possibility of also inserting the screw through the plate at an inclination. Furthermore, a bone plate is proposed which has the shape of an arc of a circle in the longitudinal axis of the plate and which requires less bending, particularly on the human lower jaw, and adapts to the bone in a more ideal manner.

In lieu of complex data analysis of these wavelengths to determine values representing the concentration of the analyte in an examined specimen, the semiconductor pump laser or lasers are modulated as a plurality of tone frequencies, where at least a first of the modulation frequencies is below the maximum frequency response of the fiber laser so that the first modulation effectively modulates the pump emission wavelength and a first emission wavelength of the fiber laser in the hybrid laser combined output, and at least a second of modulation frequencies is above the maximum frequency response of the fiber laser so that the second modulation effectively modulates the pump emission wavelength but not the first emission wavelength of the fiber laser in the hybrid laser combined output. Further, one or more additional modulation frequencies may be applied to the pump laser which are intermediate of the first and second modulation frequencies where it is at least responsive to at least one further emission wavelength of the fiber laser and also provided in the hybrid laser combined output.

The present invention relates to novel methods and novel solid support materials for the tandem synthesis of two or more different oligonucleotides on the same solid support in one synthetic run. The methods involve novel support preparations comprised of two or more types of orthogonally protected anchor groups. Subsequent to the selective removal of the first of the respective protective groups, the first oligonucleotide is assembled on the deblocked anchor groups according to standard methods, preferably via phosphoramidite chemistry. Following the capping of said first oligonucleotide, the anchor groups blocked by the second type of protective group are selectively liberated and serve is the starting point for the assembly of a second oligonucleotide, and so forth.
