The study aimed to create a geospatial model to identify agroecologically and economically viable zones for the main agro-export crops in the Piura hydrographic unit. Utilizing a Geographic Information System (GIS) and considering the bio-physical requirements of the crops, the research sought to delineate areas with high aptitude from both agroecological and socio-economic perspectives. Following the FAO's agroecological zoning methodology, various layers of spatial information were overlaid to define areas with specific suitability levels. Data were collected and analyzed from governmental sources such as SENAMHI, the Ministry of Agriculture, and the Regional Government of Piura to identify zones most optimal for each crop, closely approximating reality. The process included developing a Cartographic Model using the ArcGIS Model Builder tool, simplifying the creation of agroecological ...

This study focused on evaluating the effectiveness of variouswelding processes in reducing volatile gas emissions in workenvironments, a crucial factor for occupational health andsafety. Comparative tests were carried out on three commonwelding processes: SMAW, GMAW and GTAW, with a focuson the concentration of formaldehyde and other volatileorganic compounds (VOCs) in the air. The results revealedhigh statistical significance between treatments, confirmingsubstantial differences in VOC emissions. The Tukey testidentified the GTAW (TIG) process as the most efficient, with aconcentration of total volatiles of 0.0557 mg/m³, well below thethreshold of 0.2 mg/m³, where it is expected that no irritation orsymptoms of discomfort. In contrast, the SMAW and GMAWprocesses showed concentrations that could lead to irritationor discomfort. Choosing the appropriate welding process isrevealed as a c...
