Background: Having a high Quality of Work Life (QWL) has a positive influence in care quality, however, in Mexico, little is known about QWL and even less in health care professionals and primary care. This study aims to describe strengths and areas of improvements in QWL in nursing professionals who work in primary care of Jurisdiction No. 2 in Tampico, Tamaulipas, Mexico. Methods: Cross-sectional analytical study. The CVT-GOHISALO instrument was applied, which measures QWL. Results: The study sample was composed by 67 women (95.7%) and 3 men (4.3%). The average age was 39 years old, ranging from 23 to 69 years old. A 57.1% reported living with a partner; 54% had a full time job; and 78.6% had only one job. The results of the present study showed that dissatisfaction can be found in nursing professional's QWL in public health clinics in all dimensions. Those dimensions with the greatest dissatisfaction were Inclusion in the working place, Personal development and Well-being achieved through work. The dimensions with less dissatisfaction were Institutional support, Free-time management, Work satisfaction, Safety at work. Conclusions: This study is the first attempt to determine the QWL of nursing professionals of primary care clinics in Tampico, Tamaulipas.

Human beings are attempting to take advantage of renewable natural resources by using solar cells. These devices take the sun’s radiation and convert it into electrical energy. The issue with traditional silicon-based solar cells is their manufacturing costs and environmental problems. For this reason, alternatives have been developed within the solar cell field. One of these alternatives is the dye-sensitized solar cell (DSSC), also known as Grätzel solar cells. DSSCs are a type of solar cell that mimics photosynthesis. They have a photoanode, which is formed by a semiconductor film sensitized with a dye. Some of their advantages include low-cost manufacturing, eco-friendly materials use, and suitability for most environments. This review discusses four important aspects, with two related to the dye, which can be natural or synthetic. Herein, only natural dyes and their extraction methods were selected. On the other hand, this paper discusses the nanostructures used for DSSCs, the TiO2 nanostructure being the most reported; it recently reached an efficiency level of 10.3%. Finally, a review on the novelties in DSSCs technology is presented, where it is observed that the use of Catrin protein (cow brain) shows 1.45% of efficiency, which is significantly lower if compared to Ag nanoparticles doped with graphene that report 9.9% efficiency.

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. The results showed the great potential of natural pigments for use in solar cells. The best results were obtained with the blackberry pigment, reaching a value of 7.1 mA current, open-circuit voltage (V ) of 0.72 V in 2 cm , and fill factor (ff) of 0.51 in the DSSC. This performance is well above than that currently offers by actual cells.

Protected areas (PAs) are considered as a globally accepted strategy for biodiversity conservation that demonstrates the difficulties in meeting the proposed objectives; therefore, different conservation schemes are promoted to integrate the design of interfaces that favor the exchange of knowledge among different sectors, systems and stakeholders. The objective of this study was to characterize challenges regarding the protection of natural protected areas and other biodiversity conservation schemes in Tamaulipas, Mexico. This paper analyzed 39 areas with some form of protection status in addition to the 70 national and international designations that are part of them. A document review and 13 semi-structured interviews were conducted with experts from the public, private, academic, and civil society sectors. The data were analyzed from a qualitative perspective using ATLAS.ti 9 software. The results show the overlapping of protection schemes in priority areas; the lack of policies and mechanisms that integrate the different schemes to facilitate the exchange between stakeholders; and regulatory, structural, governance, management, participation, and operational gaps, as well as the absence of comprehensive and long-term work. The importance of and challenges in articulating the different schemes and visions to achieve effective biodiversity conservation are evident.

Alcanzar la salud integral, es el principal reto del ser humano para mantener una óptima calidad de vida. Lograr la salud integral requiere del desarrollo coherente del individuo, y para ello deberá prestar atención a todos los aspectos de su vida: físicos (cuerpo), mentales, emocionales (alma) y espirituales. El desarrollo humano coherente en todas estas áreas, contribuye a crear una sociedad más sana. Numerosos estudios han encontrado que las personas sometidas a cambios familiares, sociales y culturales caracterizadas por rupturas emocionales y desorganización social o inestabilidad, están en mayor riesgo de contraer diferentes tipos de enfermedades emocionales y mentales que repercuten en la salud corporal. Para alcanzar la salud integral, se requiere un desarrollo ordenado y coherente a través de las diferentes etapas que integran la vida del individuo y atendiendo sus diferentes áreas de desarrollo. También se requiere el apoyo del núcleo familiar y una correcta alimentación para cada uno de los elementos que integran el ser.  En este artículo se realizó una revisión sobre los avances científicos relacionados con la coherencia en el desarrollo integral y la salud.
