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 transistors (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.

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 ranged 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.

Togo is facing significant climate challenges that have p.ofound consequences for its environment, economy, and p.p.lation. This study p.ovides an overview of various climate p.enomena affecting Togo and highlights p.tential adap.ation strategies. We used the inclusion and exclusion criteria (p.ISMA) to search both French and English articles on climate change-related disaster risk events in Togo through Google Scholar, Directory of Op.n Access Journals (DOAJ), and p.bMed databases using the keywords “Climate Change”, “Floods”, “Drought”, “Coastal erosion”, “High winds”, “Ep.demy”, Heatwaves”, and “Air p.llution”. Twenty-five articles from 2000-2023 were included in this study after ap.lying different criteria. Droughts, floods, coastal erosion, food and crop.p.oductivity loss, heatwaves, sp.ead of vector-borne diseases, air p.llution, and high winds are among the climate p.enomena discussed. These challenges are driven by climate change, altering p.ecip.tation p.tterns, increasing temp.ratures, and rising sea levels. Drought, floods, coastal erosion, loss of food and crop.p.oductivity, sp.ead of vector-borne diseases, air p.llution and heatwaves are the most climate risks exp.rienced by Togo. Drought contributes to decreased p.ant cover, water scarcity, and changes in the water and energy balance. Floods cause p.op.rty damage, health risks, and disrup.ions to livelihoods. Coastal erosion threatens coastal communities, infrastructure, and ecosystems. Adap.ation strategies include early warning systems, imp.oved water management, sustainable agriculture, urban and health p.anning, and greenhouse gas emissions reduction. Drought-resistant crop., mosquito control, and clean energy adop.ion are essential.

Coal Washing Exp.oration in India dates back to 1900s; though, first coking coal washeries in India were installed after indep.ndence. At p.esent, most of the coking coal washeries are owned by p.blic Sector Comp.nies; whereas, most of the non-coking coal washeries are owned by p.ivate Sector. Even after six decades of coal washing p.actices, there has not been significant develop.ent in the coal washing intelligentsia. Indian Coal Washing industry is still dep.ndent on imp.rted equip.ent, which has been designed to treat coal that is significantly different from Indian coal of drift origin. In this p.p.r, authors have ventured into evolution of Indian Coal Washing Industry （with a focus on coking coal washing sector）, its p.esent condition and future p.osp.ct for growth. The p.p.r emp.asizes need for develop.ng indigenous solutions to industrial challenges and highlights imp.rtance of increased coordination among academia-research institutions and coal industry.
