Published: December 2022

En el trabajo se exponen los resultados de la sistematización de la experiencia práctica de trabajo comunitario integrado, con las comunidades complejas en la cirscunscripción 72 en el municipio Holguín. El desarrollo de acciones del grupo de trabajo integral comunitario condujo al mejoramiento de las condiciones económicas, medio-ambientales y socio-culturales de la comunidad, donde fueron atendidos e involucrados individuos socialmente vulnerables, que fueron transformadas como resultado de esas acciones comunitarias. El proyecto “Alas de Colibrí”, representó una oportunidad para el cambio, una perspectiva renovadora que les permitió insertarse a la vida social, al trabajo y a la comunidad. Se muestra como el trabajo del grupo de trabajo comunitario integrado, cuando es coherente y verdaderamente integral de todos los factores promotores del cambio, se obtienen resultados positivos en la solución a los problemas y las insuficiencias detectadas. Se pone énfasis en la atención diferenciada a las mujeres, niños, familias e individuos en situación de vulnerabilidad, y especialmente a aquellas que necesitan de acciones de reeducación y reinserción social. Se emplearon métodos de la investigación acción participativa, ponderando la participación social como categoría de partida.

ABSTRACTIn the work, the results of the systematization of the practical experience of integrated community work are exposed, with the complex communities in the district 72 in the Holguín municipality. The development of actions of the comprehensive community work group led to the improvement of the economic, environmental and socio-cultural conditions of the community, where socially vulnerable individuals were cared for and involved, who were transformed as a result of these community actions. The "Wings of Hummingbird" project represented an opportunity for change, a refreshing perspective that allowed them to insert themselves into social life, work and the community. It is shown how the work of the integrated community work group, when it is coherent and truly comprehensive of all the factors that promote change, positive results are obtained in solving the problems and insufficiencies detected. Emphasis is placed on differentiated care for women, children, families and individuals in vulnerable situations, and especially those who need reeducation and social reinsertion actions. Participatory action research methods were used, considering social participation as the starting category.

Aprendizajes que nos deja la Covid-19. Una mirada sociológica
Authors: Hernández-Freeman Leopoldo 
Published: December 2022

Muchos son los análisis que se han realizado sobre la pandemia COVID-19 desde diferentes ciencias. En sentido general, estos se han centrado, fundamentalmente, en las causas que la generaron, sus características y su impacto. También se han emitido diversos criterios sobre los aprendizajes que nos deja como sociedad la crisis total que ha generado. La mirada sociológica que se propone, más que brindar un análisis teórico, pretende sintetizar aquellas aristas que tienen que ver con su impacto social, y, en especial, identificar aprendizajes que sirvan para perfeccionar el funcionamiento, la organización y la responsabilidad social de las instituciones del Estado. Son, sencillamente, algunas referencias que, investigadores, decisores, líderes y población en general pudieran tomar como punto de partida para el diseño de políticas sociales, y estrategias de cambio y desarrollo social.

ABSTRACT
The analysis of the COVID-19 pandemic has been approached from different sciences, mainly focused on its causes, features and impact. The knowledge and learning that the crisis contributed as a society has also generated different criteria. The proposed sociological approach, rather than providing a theoretical analysis, focuses on social impact and mainly, identify knowledge that improves the functioning, organization and social responsibility of the State institutions involved. Researchers, decision makers, leaders and the general population could consider our reference as a benchmark to design social policies and strategies for change and social development.

Authors: Velázquez-Rodríguez Kerslin 
Published: December 2022

La ciencia, la tecnología y la innovación representan pilares fundamentales para el desarrollo económico y social y es por ello que se incentiva la concepción e implementación de formas organizativas, de financiación y gestión de la actividad científica de manera que se introduzcan de forma sistemática los resultados en los procesos productivos y de servicios, sustentados por el marco institucional y regulatorio establecido y que, en definitiva, se genere la satisfacción de las actuales demandas de la sociedad cubana. El artículo analiza la importancia de la articulación de las universidades con los contextos territoriales en las que éstas se desenvuelven favorece la relación de las capacidades cognitivas, científicas y tecnológicas con la sociedad. Asimismo, se aborda, cómo las universidades pueden contribuir a fomentar el bienestar humano en los territorios, toda vez que se logre ampliar la producción local del conocimiento y la innovación, sobre todo mediante recursos propios. En esos contextos, cuando las personas se apropien de determinados conocimientos y tecnologías, su rol cambia, de ser pacientes se convierten en agentes. Esta realidad conduce a plantearse un modo de actuación basado en la innovación, el cual se apoye además en procesos formativos, investigativos y extensionistas de la universidad en estrecho vínculo con las necesidades de los territorios.

ABSTRACT
Science, technology and innovation represent fundamental pillars for economic and social development and that is why the conception and implementation of organizational forms, financing and management of scientific activity is encouraged so that the results are systematically introduced. in the productive and service processes, supported by the established institutional and regulatory framework and that, ultimately, the satisfaction of the current demands of Cuban society is generated. The article analyzes the importance of the articulation of universities with the territorial contexts in which they operate, favoring the relationship of cognitive, scientific and technological capacities with society. Likewise, it addresses how universities can contribute to promoting human well-being in the territories, whenever it is possible to expand the local production of knowledge and innovation, especially through their own resources. In these contexts, when people appropriate certain knowledge and technologies, their role changes, from being patients they become agents. This reality leads to consider a mode of action based on innovation, which is also supported by training, research and extension processes of the university in close connection with the needs of the territories.

Authors: Tropina Dar'ya Vladimirovna , Sergeev Dmitrii Gennad'evich 
Published: December 2022

Rural tourism today is one of the new and actively developing types of tourism in Russia. Due to political and epidemiological factors, the approach to choosing a place of rest has changed and many modern tourists prefer to travel around Russia, getting acquainted with the geographical, agro-industrial, gastronomic, ethno-cultural characteristics of rural areas. The article analyzes the state of legal regulation of rural tourism at the present stage. Program documents, federal laws, by-laws containing norms regulating the provision of services in rural tourism are considered. The main provisions of the program for providing state support in the field of rural tourism – the "Agrotourism" grant - are revealed and the problems associated with the inability of some agricultural producers to become grant applicants due to non-compliance with the rules for registration of individual entrepreneurs engaged in agriculture are raised. Also, the article analyzes the requirements for accommodation facilities in agriculture and tourism adopted in November 2022, points out the shortcomings of the federal executive authority when adopting an order approving such requirements related to ignoring the specifics of providing services in rural areas, the performers of which are non-professional participants in the tourism industry. In conclusion, it describes the currently most effective way to promote services in rural tourism using online aggregators. The conclusion is made about the importance of support by state authorities and local self-government of agricultural producers wishing to develop rural tourism in parallel with the implementation of agricultural activities.

Authors: Odozi Efeota Bright , Ajayi Olutayo Ifedayo 
Published: December 2022

Background: The association of combustive emission has been inter-related with haematologic parameters and a likelihood to pro-inflammatory state. This research is aimed at assessing the impact of vehicular emission on erythrocyte level and red cell indices of occupationally exposed subjects.
Methods: The level of haemoglobin concentration, haematocrit, red blood cells, mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, and red cell distribution width were determined in four hundred subjects with the aid of Mythic 22 haematology autoanalyser.
Results: The comparison of the haemoglobin and haematocrit shows that the value of mean ± standard error value of generator exposed and mechanics respectively were significantly higher than the other groups (p< 0.03). On the otherhand, the red blood cell count for generator exposed and mechanics ranked higher than the other groups (p< 0.03). The mean cell volume (MCV) of generator exposed and mechanics were 86.57±0.08 fl and 84.49±1.04 fl respectively while control and drivers had values of 93.24±1.13 fl and 93.22±1.13 fl respectively (p< 0.03). The mechanics recorded a mean cell haemoglobin (MCH) of 26.92±0.40 pg which was significantly lower (p< 0.04) than the control (30.37±0.47 pg), generator exposed (39.68±6.38 pg) and drivers (30.42±0.47 pg). Conclusion: The differences amongst the groups and none of the groups were within the medically acceptable ranges which is a pointer to the fact that there might be an underlying inflammatory condition which might be due to occupational exposure.

Published: December 2022

AbstractPurposePatient Specific QA (PSQA) by direct phantom measurement for all intensity modulated radiation therapy (IMRT) cases is labor intensive and an inefficient use of the Medical Physicist's time. The purpose of this work was to develop a hybrid quality assurance (QA) technique utilizing 3D dose verification as a screening tool to determine if a measurement is necessary.MethodsThis study utilized Sun Nuclear DoseCHECK (DC), a 3D secondary verification software, and Fraction 0, a trajectory log IMRT QA software. Twenty‐two Lung stereotactic body radiation therapy (SBRT) and thirty single isocentre multi‐lesion SRS (MLSRS) plans were retrospectively analysed in DC. Agreement of DC and the TPS dose for selected dosimetric criteria was recorded. Calculated 95% confidence limits (CL) were used to establish action limits. All cases were delivered and measured using the Sun Nuclear stereotactic radiosurgery (SRS) MapCheck. Trajectory logs of the delivery were used to calculate Fraction 0 results for the same criteria calculated by DC. Correlation of DC and Fraction 0 results were calculated. Phantom measured QA was compared to Fraction 0 QA results for the cases which had DC criteria action limits exceeded.ResultsCorrelation of DC and Fraction 0 results were excellent, demonstrating the same action limits could be used for both and DC can predict Fraction 0 results. Based on the calculated action limits, zero lung SBRT cases and six MLSRS cases were identified as requiring a measurement. All plans that passed the DC screening had a passing measurement based PSQA and agreed with Fraction 0 results.ConclusionUsing 95% CL action limits of dosimetric criteria, a 3D secondary dose verification can be used to determine if a measurement is required for PSQA. This method is efficient for it is part of the normal clinical workflow when verifying any clinical treatment. In addition, it can drastically reduce the number of measurements needed for PSQA.

AbstractThe magnetoresistance (MR) in nonmagnetic materials continues to be a fertile research area in materials science. The search for giant, positive MR has been limited to a rather small window of materials such as high‐mobility semimetals in single‐crystalline form. Here, the observation of a very large positive MR in metallic Pt5P2 in polycrystalline form is reported. The observations reveal that improvement of the crystallinity results in a significant enhancement of the positive MR, exceeding 10 000% at 9 T, comparable to high‐mobility semimetals. Based on first‐principles calculations combined with magnetotransport and thermoelectric measurements, the Fermi surface of Pt5P2 is found to consist of a collection of multiple electron and hole pockets compensating one another, along with a characteristic pocket continuously connected to the adjacent Brillouin zone, together with possible topologically protected band crossings. This work extends the landscape of high MR candidate materials to polycrystalline metals, which demonstrates the importance of crystallinity and purity of the samples for the optimization of the MR.

Published: December 2022

AbstractThe United States National Aeronautics and Space Administration's (NASA's) mandate is a human mission to Mars in the 2030s and sustained exploration of Mars requires in situ resource utilization (ISRU). Exploiting the Martian water cycle (alongside perchlorate salts that depress water's freezing point to <213 K) and the available 95 vol.% atmospheric CO2, we detail an ultra‐low temperature (255 K) CO2–H2O electrolyzer to produce methane fuel and life‐supporting oxygen on Mars. Our polarization model fit experimental Martian brine electrolyzer performance and predicted CO2 electrolysis occurring at comparatively lower potentials (vs. water electrolysis) on Mars. A hypothetical 10‐cell, 100 cm2 electrode‐area‐per‐cell electrolyzer produced 0.45 g W−1 day−1 of CH4 and 3.55 g W−1 day−1 of O2 at 2 V/cell and 50% electrolyzer faradaic efficiency versus a best‐case production of 2.5 g W−1 day−1 of O2 by the Mars Oxygen in situ Resource Utilization Experiment (MOXIE) from NASA's Mars 2020 mission (MOXIE produces no fuel). Material performance requirements are presented to advance this technology as an energy‐efficient complement to MOXIE.
Advanced pharmaceutical manufacturing: A functional definition

Published: December 2022

AbstractThe term “Advanced Pharmaceutical Manufacturing” (APM) has become an ubiquitous buzzword with deep potential policy implications. There is a real danger that APM will be seen as a general panacea for solving economic woes and drug shortages, devoiding it from specific meaning, and depriving the technical community of focus much needed for its development and implementation. This paper first discusses several semantic definitions of APM that have been proposed in the field. A functional definition of APM is then presented as: A system that is designed using predictive models, where automation minimizes human intervention while enabling closed loop process control and real time quality assurance, where performance has been optimized to maximize desired process goals, where flexible amounts of product with equivalent attributes can be manufactured, and where equivalent processes can be implemented at multiple locations to manufacture products with equivalent critical quality attributes. The proposed definition is presented to motivate discussion and elicit contributions from other stakeholders, and to contribute to the development of a consensus framework for design, development, implementation, and evaluation of APM.

Published: December 2022

AbstractIn class Ib ribonucleotide reductases (RNRs) a dimanganese(II) cluster activates superoxide (O2⋅−) rather than dioxygen (O2), to access a high valent MnIII−O2−MnIV species, responsible for the oxidation of tyrosine to tyrosyl radical. In a biomimetic approach, we report the synthesis of a thiolate‐bound dimanganese complex [MnII2(BPMT)(OAc)2](ClO)4 (BPMT=(2,6‐bis{[bis(2‐pyridylmethyl)amino]methyl}‐4‐methylthiophenolate) (1) and its reaction with O2⋅− to form a [(BPMT)MnO2Mn]2+ complex 2. Resonance Raman investigation revealed the presence of an O−O bond in 2, while EPR analysis displayed a 16‐line St=1/2 signal at g=2 typically associated with a MnIIIMnIV core, as detected in class Ib RNRs. Unlike all other previously reported Mn−O2−Mn complexes, generated by O2⋅− activation at Mn2 centers, 2 proved to be a capable electrophilic oxidant in aldehyde deformylation and phenol oxidation reactions, rendering it one of the best structural and functional models for class Ib RNRs.

AbstractMany strategies have been developed for constructing anisotropic hydrogels, however, it remains a challenge to fabricate hydrogels with anisotropic nanocrystalline domains from intrinsically soft networks. Here, we report a naphthotube‐based polyrotaxane‐containing hydrogel that can be reinforced via mechanical training. During the training process, the hydrogel can adopt reorientation of polymer chains to form anisotropic structures driven by external uniaxial force. Due to the multiple hydrogen bonding sites and movable feature of naphthotube, the sliding of naphthotube on PEG chains simultaneously inducing the zipping of adjacent polymer chains to form densely anisotropic nanocrystalline domains through hydrogen bonded networks. Thus, the trained hydrogel exhibits an enhanced tension stress of ≈110 kPa, which realize a remarkable enhancement of ≈10 times compare to initial state. This study provides a new tactic for improving the mechanical performance of soft materials.
