- Obesity is a complex condition linked to various non-communicable diseases, primarily driven by poor diet and sedentary lifestyles, which affects adolescents' health and well-being.
- The study aimed to create and validate a tool designed to evaluate eating habits, physical activity, and emotional states among adolescents in Tamaulipas, Mexico, employing a comprehensive methodological approach including expert evaluations and statistical analyses.
- The final instrument, consisting of 46 items with strong validity and reliability metrics, is deemed effective for assessing risk factors associated with healthy habits among adolescents.
The development of photovoltaic panels has improved the conversion of solar radiation into electrical energy. This paper deals with the electrical and thermal characteristics (voltage, current, and temperature) of photovoltaic solar cells sensitized with natural pigments (dye-sensitized solar cell, DSSC) based on a titanium dioxide semiconductor. Several natural pigments (blackberry, beets, eggplant skin, spinach, flame tree flower, papaya leaf, and grass extracts) were evaluated to determine their sensitizing effect on titanium dioxide.
