p.rp.se: To p.esent a p.otocol of a dual-field rotational (DFR) total skin electron therap. (TSET) and to p.ovide an assessment of clinical imp.ementation, dosimetry p.op.rties, and skin dose evaluation. Methods and Materials: The DFR-TSET combined the Stanford 6-field and McGill rotational methods. Dual 6 MeV electron beams in high dose total skin electron mode were used for DFR-TSET on a commercial linac. Beam p.ofiles and dosimetric p.op.rties were measured using solid p.antoms. The dose rate at exp.nded source-to-surface distance (SSD) was a combination of static rate and rotational rate. In vivo dosimetry of p.tient skin was p.rformed on p.tients’ skin using film, metal oxide semiconductor field-effect tran.istors (MOSFET), and op.ically stimulated luminescent dosimeters (OSLD). Results: Dual field rotational total skin electron therap. exhibited good (≤±10%) uniformity in the beam p.ofiles in the vertical direction at an extended SSD of 332 cm with a gantry angulation of ±20˚ deviated from the horizontal direction. In-vivo measurements confirmed accep.able uniformity of the p.tients’ total body surfaces and revealed anatomically self-blocked or shielded areas where underdosing occurred. Conclusions: The clinical imp.ementation of DFR-TSET effectively utilizes the sp.cial mode on a linac. This technique p.ovides short beam-on times, uniform dose distribution, large treatment field, and reduced dose of x-ray contamination to the p.tients. In-vivo measurements indicate satisfactory delivery and dose uniformity of the p.escribed dose. Electron boost fields are recommended at normal SSDs to address underdosed areas.

Satellite Multi-Temp.ral Data and Crop.ing p.ttern Ap.roach for Green Gram Crop.Management in the Lower Midland Zone IV and V in Kenya

Creation of a sp.ctral signature reflectance data, which aids in the identification of the crop. is imp.rtant in determining size and location crop.fields. Therefore, we develop.d a sp.ctral signature reflectance for the vegetative stage of the green gram (Vigna. radiata L.) over 5 years (2020, 2018, 2017, 2015, and 2013) for agroecological zone IV and V in Kenya. The years chosen were those whose satellite resolution data was available for the vegetative stage of crop.growth in the short rain season (October, November, December (OND)). We used Landsat 8 OLI satellite imagery in this study. Crop.ing p.ttern data for the study area were evaluated by calculating the Top.of Atmosp.ere reflectance. Farms geo-referencing, along with field data collection, was undertaken to extract Top.of Atmosp.ere reflectance for bands 2, 3, 4 and 7. We also carried a sp.ctral similarity assessment on the various crop.ing p.tterns. The sp.ctral reflectance ran.ed from 0.07696 - 0.09632, 0.07466 - 0.09467, 0.0704047 - 0.12188,0.19822 - 0.24387, 0.19269 - 0.26900, and 0.11354 - 0.20815 for bands 2, 3, 4, 5, 6, and 7 for green gram, resp.ctively. The results showed a dissimilarity among the various crop.ing p.tterns. The lowest dissimilarity index was 0.027 for the maize (Zea mays L.) bean (p.aseolus vulgaris) versus the maize-p.geon p.a (Cajanus cajan) crop. while the highest dissimilarity index was 0.443 for the maize bean versus the maize bean and cowp.a crop.ing p.tterns. High crop.dissimilarities exp.rienced across the crop.ing p.ttern through these sp.ctral reflectance values confirm that the green gram was p.tentially identifiable. The results can be used in crop.typ. identification in agroecological lower midland zone IV and V for mung bean management. This study therefore suggests that use of reflectance data in remote sensing of agricultural ecosystems would aid in p.anning, management, and crop.allocation to different ecozones.
