Two experiments were conducted at the State University of Western Paraná (UNIOESTE), in Cascavel, Paraná, Brazil: one in a protected environment and the other in open field conditions. The experimental design was completely randomized, with eight treatments and four replications (32 plots), as follows: T1-(Vegetative), T2-(Reproductive), T3-(Grain Formation), T4-(Vegetative and Reproductive), T5-(Vegetative and Grain Formation), T6-(Reproductive and Grain Formation), T7-(None of the Stages), and T8-(Vegetative, Reproductive, and Grain Formation). The substrate consisted of red soil and vermicompost humus placed in PVC pots. Irrigation was based on reference evapotranspiration (ETo), estimated using the Thornthwaite, Camargo, and Penman-Monteith methods adapted to the region. The cultivation in the protected environment was conducted under a high tunnel structure without temperature control. Irrigation was applied locally. In the field, sowing took place in an open area without climate control. In both environments, the plants’ water demand was adjusted using the crop coefficient (Kc), considering the phenological stages. The variables analyzed included plant height, number of leaves and capitula, stem and capitulum diameter, fresh and dry biomass (shoot and root), and yield. Statistical analysis was performed using the F test at a 5% significance level with the Sisvar software. In the greenhouse, T8 was significant for: root length (17 cm) and stem length (144.50 cm), fresh mass (3.49 g) and dry mass (1.80 g) of roots, fresh mass (40.37 g) and dry mass (8.89 g) of stems, stem diameter (8.85 mm), number of capitula (20.25), and number of leaves (35.50). Capitulum diameter showed no significant differences. Among the combined treatments, T4 stood out, and among the isolated ones, T1 was the most prominent. In the open field, T8 also showed the best results, particularly for: fresh mass (4.23 g) and dry mass (0.85 g) of roots, fresh mass (46.6 g) and dry mass (8.19 g) of stems, stem diameter (8.53 mm), number of capitula (33), and number of leaves (49). For certain variables, no significant differences were observed: stem and root length, number and weight of seeds, one thousand-grain weight, capitulum diameter, and productivity indicators. Among the combined treatments, T6 had the highest values. Among the isolated treatments, T3 showed the highest mean. T3 proved to be sensitive to water stress, and continuous irrigation enhanced growth and productivity.

Accelerated urbanization, coupled with the replacement of vegetated areas by impermeable surfaces, has intensified urban heat island (UHI) effects, posing challenges to environmental quality and public health. The research employed remote sensing techniques, utilizing Landsat 8 satellite imagery processed with QGIS software. LST data from the summer months (January, February, and March) of both years were analyzed, alongside vegetation distribution assessed through the Normalized Difference Vegetation Index (NDVI). Surface temperatures were derived from the satellite’s thermal band, while NDVI calculations employed the near-infrared and red spectral bands. For comparative and validation purposes, descriptive statistical analyses were conducted, including the Shapiro-Wilk test to assess data normality and Pearson’s correlation coefficient to examine the relationship between vegetation cover and surface temperature. The findings confirmed a significant increase in UHI intensity in Cascavel over the ten-year period, largely attributed to unplanned urban expansion and the reduction of vegetative cover. Although a slight increase in maximum NDVI values was observed, the existing vegetation proved insufficient to mitigate surface warming. The weakening correlation between vegetation and LST over time further indicates a declining capacity for thermal regulation. This study underscores the urgent need for more effective public policies focused on expanding urban green areas and promoting sustainable urban planning to mitigate local climatic impacts and enhance urban resilience.

To reach the result, 30 professionals from the photovoltaic energy market in Cascavel - PR were interviewed. The survey was designed to contain questions about the nine quadrants of the BMC, the profile of the interviewees and their knowledge about photovoltaic tiles. The answers were transformed into numbers for better understanding. The BMC is a tool used for strategic planning for companies, projects, products and research. Through this tool, it is possible to visualize all the points of the planning in a single table, acting as a map to achieve the proposed objective. In short, it was discovered that for the photovoltaic tile industry, customers are those looking for aesthetics for a new home, the product has the advantage of being integrated into the construction, contact with the customer can be through websites and social networks, offering quality products and after-sales, it is through local energy generation and tile sales that it is possible to generate income, engineers are the greatest resources of the enterprise, one of the main key activities is prospecting customers, an important partnership is with photovoltaic material suppliers and finally, the greatest costs of this business model are electrical inputs and photovoltaic equipment. At the end of the research, it was possible to identify all nine quadrants of the BMC and organize them in a single table, with the objective of helping companies that work with photovoltaic tiles to know which steps they should follow to be successful in business. With some adaptations, the result of this research can also help other companies in the photovoltaic sector to manage their businesses assertively.

However, intensive soil use, destruction of native forests, and irresponsible use of natural resources have caused significant problems for soil quality and the environment. The objective of this study was to evaluate the impacts of soil exploitation methods on the physical and chemical attributes of a clayey Oxisol in the western region of Paraná. The soil exploitation methods were evaluated at the Institute for Rural Development of Paraná (IDR- Paraná), located at Santa Tereza do Oeste, Paraná, Brazil. Six soil exploitation methods were evaluated [No-tillage system with crop rotation (NT C/ROT), no-tillage system without rotation (NT W/ROT), fruit cultivation, pasture, crop-livestock integration (CLI), and native forest], with four replications. Physical analyses (soil bulk density, macroporosity, microporosity, total porosity, saturated hydraulic conductivity, and geometric mean diameter (GMD)) and chemical analyses [pH (CaCl2) and levels of potassium, phosphorus, calcium, magnesium, and organic matter] were performed at depths of 0-10, 10-20, 20-30, and 50-60 cm. The data were subjected to the non-parametric Kruskal-Wallis test at a 5% significance level and correlation analysis. The no-tillage system with crop rotation showed chemical soil conditions similar to those of native forest, followed by CLI and fruit cultivation. Pasture showed intermediate changes in soil chemical attributes. The no-tillage system without rotation showed signs of possible nutrient leaching and depletion, as well as low organic matter replenishment. Surface soil density was lower in no-tillage systems compared to perennial systems such as CLI, pasture, and fruit cultivation. Deep soil macroporosity in fruit cultivation and pasture systems was similar to native forest. Regarding the geometric mean diameter in the soil surface layer, the no-tillage system with rotation was similar to native forest. In general, positive correlations were observed between pH, Ca, K, base saturation (BS), cation exchange capacity (CEC), and base saturation percentage (V) with macroporosity and saturated hydraulic conductivity (Ksat), and negative correlations between soil density and chemical soil attributes. A correlation was found between soil macroporosity and Ksat, given that they are dependent variables: the greater the percentage of macropores, the higher the water infiltration in the soil.
