We will report an excerpt of Appendix A to FAR 43: major alterations, major repairs, and preventive maintenance. (1) Airframe major repairs. Repairs to the following parts of an airframe and repairs of the following types, involving the strengthening, reinforcing, splicing, and manufacturing of ...
The eight types of sails described above are illustrated in Fig. 1. Some have been flight tested with operational heritage, while some remain at the concept stage, planned to reach maturity in the coming decades. Against this backdrop, it is time to recognise the advantages of space sails ...

cuFFT: Release 12.3 ▶ New Features ▶ Callback kernels are more relaxed in terms of resource usage, and will use fewer registers. ▶ Improved accuracy for double precision prime and composite FFT sizes with factors larger than 127. ▶ Slightly improved planning times for some FFT sizes....
The project will advance forest biomass innovation and support development of alternative construction materials by investigating the strengths and potential uses of a green concrete containing forest biomass ash. Innovative Bioproduct Manufacturing funding stream ...
Materials and methods Study area and layout of sampling plots We used data from 51 circular plots of 0.1 ha49, delineated in the Sudanian and Sudano-Guinean zones of Benin (Fig.2). The study area belongs to the Sudano-Sahelian zone, which supports a wide spectrum of abiotic and biotic ...
45 Certain non-destructive methods, such as eddy currents, for inspecting conductive materials while others like strain gauges and fiber Bragg gratings are adaptable to composite electrode materials. Acoustic emission techniques identify fatigue damage, albeit requiring precise capture of damage progression,...
2. Materials and methods 2.1. Study area and data origin We used a dataset of 249 sampling sites for macroinvertebrates, 195 sampling sites for diatoms and 103 sampling sites for fishes located in mountainous (altitude 200–800 m a.s.l.) andlowlandregions (altitude below 200 m a.s.l.)...
