Introduction: The World Health Organization (WHO) points out that 3 million deaths per year caused by cardiopulmonary diseases are related to exposure to air pollution. Objective: To estimate areas of concentration of PM2.5 in Bogotá according to the WHO Air Quality Guidelines (AQG) for cardiopulmonary diseases during the period 2014-2015. Materials and methods: We conducted an ecological study with geostatistical techniques. We calculated the PM2.5 averages for six hour-periods distributed throughout the day in four time slots, which were classified according to daily and annual WHO AQG. Results: The locality of Kennedy presented the highest concentrations of PM2.5 in all time slots. The values registered in this area classified within the daily and annual AQG showed that the locality would present an increase of 1.2% and 9% in cardiopulmonary mortality in the short and long term, respectively. Conclusion: The time slots from 0:00 to 6:00 h y from 12:00 to 18:00 h met the annual AQG value of 10 μg/m3 in a part of the eastern zone of the city; in the rest of the city, in these same time slots, intermediate objectives 2 and 3 were met, which means increases by 9% and 3% in the cardiopulmonary mortality according to the AQG, respectively.

This study presents the design, modeling, and validation of a mixing screw for energy-efficient single-screw extrusion. The screw features a short length-to-diameter (L/D) ratio of 8:1 and incorporates double flights with variable pitch and counter-rotating mixing slots. These features promote enhanced plastication by breaking up the solid bed and improving thermal homogeneity through backflow mechanisms relieving a 3.

This paper demonstrates real-time, label-free, contact-based glucose sensor design of inset-fed Microstrip Patch Antenna (MSPA) genres: Slotted Microstrip Patch Antenna (SMSPA) and Through-hole Microstrip Patch Antenna (THMSPA). In SMSPA, multiple slots are created along the width edge of the patch. In THMSPA, a through-hole is introduced across the antenna including all the layers: patch, substrate and ground conductor of the MSPA.

Malnutrition is an escalating concern in low-and-middle-income countries (LMICs), including Ecuador, particularly within rural settings. To address this issue, food forests emerge as a promising intervention. This research protocol outlines a controlled intervention in the province of Santa Elena, aiming to evaluate the efficacy of a food forest in enhancing nutritional outcomes, with potential implications for broader replication.
