Abstract AIM Despite a wide variety of models found in literature, choosing the right one can be difficult as many of them are lacking precise methodology. This study aims to analyze and compare original burn models in terms of burn device and technique, parameters, and wound depth assessment. METHODS A systematic search was performed according to PRISMA guidelines on studies describing original experimental burn models in rats. The adapted PICO formula and ARRIVE checklist were followed for inclusion and assessment of quality of studies. Characteristics of animals, burn technique, burn parameters and method of histological confirmation of burn depth were recorded. RESULTS Twenty-seven studies were included in the final analysis. Most studies used direct contact with skin for burn infliction (n=20). The rat’s dorsum was the most common site (n=18). Ten studies used manually controlled burn devices, while ten designed automatic burn devices with control over temperature (n=10), exposure time (n=5), and pressure (n=5). Most studies (n=7) used a single biopsy taken from the center of the wound to confirm burn depth immediately after burn infliction. CONCLUSION From the wide variety of burn models in current literature, our study provides an overview of the most relevant experimental burn models in rats aiding researchers to understand what needs to be addressed when designing their burn protocol. Models cannot be compared as burn parameters variate significantly. Assessment of burn depth should be done in a standardized, sequential fashion in future burn studies to increase reproducibility.

A região do Alto Irani situada no oeste catarinense, possui 15% da vegetação original, tem caracteristicamente a silvicultura praticada em áreas inferiores a 10 hectares, registra índices preocupantes de incêndios florestais, principalmente em reflorestamentos. Como inexiste na região qualquer programa oficial sendo desenvolvido por órgão público, a Universidade do Oeste de Santa Catarina - UNOESC, através do seu campus de Xanxerê, desenvolveu um projeto de capacitação que inclui bombeiros, trabalhadores de empresas florestais, funcionários públicos com função de extensão rural e representantes das comunidades indígenas. O projeto de extensão universitária é oferecido gratuitamente, tendo por objetivos difundir técnicas de queima controlada para os agricultores, técnicas de prevenção para pequenos e médios silvicultores, qualificação técnica a bombeiros visando o desenvolvimento de atividades de prevenção e combate e, principalmente, a composição de uma força tarefa qualificada para o combate a incêndios florestais em todos os 14 municípios da região. Abstract The region of Alto Irani situated in the west of Santa Catarina possesses 15% of its original vegetation, characteristically it has silviculture practiced in areas inferior to 10 hectare, registers worrying indexes of forest fires, mainly in areas of reforestation. As there is not in the region any official program being developed by a public department, the Universidade do Oeste de Santa Catarina - UNOESC, via its campus situated in Xanxerê, developed a qualification project that includes firemen, workers from forest companies, public officers whose function is rural extension and representatives of Indian communities. The university extension project is offered free of charge, it has as objectives to spread techniques of controlled burn for the agriculturists, techniques of prevention for small and medium silviculturists, technical qualification for firemen with the objective of developing activities for prevention and combat of fires and mainly the composition of a group qualified for fighting against forest fires in all the 14 cities in the region.

Pozzolanic reactions of RHA entirely depends on controlled burning condition. The current study illustrates the effects of controlled burn rice husk ash (RHA) on the geotechnical properties of A-2-4 type soil. The compactibility, bearing capacity, compressive strength, and shear strength were investigated as the important geotechnical properties on soil with 0%, 5%, 10%, and 15% of RHA admixtures. Considering the 7-day moist curing, standard Proctor compaction tests, California Bearing Ratio (CBR) tests, Unconfined Compressive Strength (UCS) tests, Consolidated-Drained (CD) Triaxial Compression tests, and Scanning Electron Microscopy (SEM) tests were conducted on soil-RHA combinations. The test results showed that the optimum moisture content increased, but MDD reduced with the increment of RHA content. Soil with 5% RHA showed the increase of CBR (39.5%), UCS (6.0%), modulus of deformation (56.3%), cohesion (11.8%), and angle of internal friction (6.3%) compared to control specimen which indicated that the application of burnt RHA at a controlled temperature significantly enhanced the geotechnical properties of soil. SEM image on soil with 5% RHA also observed the best microstructural development.
