Breeding Quality Protein Maize (QPM): Protocols for Developing QPM Cultivars

2008
This manual is intended for maize breeders who would like to start developing quality protein maize (QPM) cultivars. It is a compilation and consolidation of several breeding protocols successfully used at CIMMYT over two decades of QPM development and breeding.

Broadband 2D-QPM Frequency Domain OPA

CLEO: 2015, 2015
We demonstrate broadband mid-IR frequency-domain OPA (FOPA) in the Fourier-plane of a 4f pulse shaper via two-dimensional (2D) quasi-phasematching (QPM) device adapted to the pump intensity profile and spatial chirp of the mid-infrared beam.

Identification of residual pesticides in water by GC/QPMS

Environmental Monitoring and Assessment, 1991
The extensive use of the broad range of pesticides employed to maintain golf courses has prompted serious environmental concerns in Japan since courses tend to be located in mountainous regions, often in close proximity to virgin water sources. Since older empirical methods are not appropriate for substance identification and determination of substance

Efficient wavelength conversion in QPM devices

Nonlinear Guided Waves and Their Applications, 1996
By now, the many potential applications of a rugged blue laser source are well established, for instance printing, displays, and optical storage. In a longer time perspective, the direct-emitting blue and green semiconductor lasers are of course the most promising candidates.

Fabrication of QPM Structures

2003
As we saw in Chapter 2, one of the most important phase matching techniques for waveguide NLO devices is quasi-phase matching (QPM) using a periodic (grating) structure. Fabrication of QPM structures in NLO materials is a key step in NLO device fabrication. This chapter presents the background and the fabrication techniques for QPM structures.

Enhancing QPM efficiency in periodic poling

CLEO/Pacific Rim 2003. The 5th Pacific Rim Conference on Lasers and Electro-Optics (IEEE Cat. No.03TH8671), 2004
QPM efficiency in periodic poling is enhanced if periodic electrodes of a shortened width are used. The maximized conversion efficiency and the optimized width of the periodic electrodes are determined from the nonlinearity distribution.

Protein quality and quantity of quality protein maize (QPM) and non‐QPM hybrids under optimal and low nitrogen conditions

Cereal Chemistry, 2021
AbstractBackground and objectivesQuality protein maize (QPM) nutritional quality involves high total protein content but reduced zein accumulation in maize endosperm, leading to increased non‐zein proteins, hence higher levels of essential amino acids such as lysine and tryptophan.

QPM wavelength conversion using engineered LiNbO3 waveguides

Conference on Lasers and Electro-Optics 2010, 2010
New waveguide technologies, namely direct bonding and dry etching, have improved damage resistance, transparent wavelength range, efficiency, and functionality. An engineered QPM structure enables variable wavelength conversion and reduces waveband crosstalk.

QPM wavelength convertersbased on stoichiometric lithium tantalate

Advanced Solid-State Photonics (TOPS), 2005
We report recent developments in periodically-poled stoichiometric lithium tantalate, suitable for high-power operation due to high thermal conductivity. Reduction of optical scattering and extension of effective apertures are reported by choosing appropriate poling parameters.

Determining a quantifiable pollution management model (QPM)

Management of Environmental Quality: An International Journal, 2005
PurposeThe aim of this research is to develop a model for environmental management from which quantifiable indication of overall environmental performance for an organisation may be derived.Design/methodology/approachThe links between environmental performance and financial performance are considered.
