Uso de nanomateriales en la agricultura y sus implicaciones ecológicas y ambientales
Authors: Vázquez-Núñez Edgar
Published: December 2022

Los recientes desarrollos en el campo de la nanotecnología han traído nuevas oportunidades para la innovación y el avance en un número sustancial de disciplinas, entre las que destaca la agricultura. Los porcentajes actuales de inanición en todo el mundo, junto con el crecimiento constante de la población, combinados con los problemas ambientales causados por la erosión y el uso de productos químicos, han puesto en primer plano la necesidad de mejoras sostenibles en la práctica agrícola, que podrían atenderse empleando nanomateriales (NMs). Los NMs se presentan como un sustituto atractivo de los materiales convencionales, debido a sus atributos y la mejora que estos representan. Los pesticidas y fertilizantes son dos de los muchos productos que han demostrado tener un gran potencial cuando se producen a nivel nanométrico, mostrando gran eficiencia en la liberación dirigida y controlada de agroquímicos, lo que se traduce en una mayor efectividad biológica, al lograr, en general, un aumento en el rendimiento y la productividad de los cultivos. No obstante, aun existen aspectos desconocidos relacionados con los efectos de la nanotecnología, por ejemplo, existe un conocimiento limitado sobre la bioseguridad, los efectos adversos, el destino y la reactividad biológica de los nanomateriales una vez que se introducen en el medio ambiente. El daño que pueden causar, no solo a los agroecosistemas, sino también a la salud humana y al medio ambiente, aún no se comprende completamente, a pesar de los numerosos esfuerzos científicos que se han realizado para evaluar el peligro intrínseco que pueden causar los NMs. Esta revisión busca servir como marco referencial al estado de la nanotecnología en la agricultura: desarrollos, aplicaciones y riesgos conocidos. Se revisan las características de los NMs aplicados en agricultura, junto con los resultados obtenidos de las pruebas de comportamiento y destino con respecto a las especies vegetales. Finalmente, se analizan las interacciones reportadas entre los componentes bióticos y abióticos de los ecosistemas expuestos, presentando un estudio sobre el estado y la dirección de la nanoagricultura.

Authors: Coello de la Rosa Alexandre
Published: December 2022

Entre 1635 y 1641 el gobernador de Filipinas, Sebastián Hurtado de Corcuera, y el arzobispo de Manila, fray Hernando Guerrero, mantuvieron un agrio enfrentamiento, con ramificaciones en la Real Audiencia, el cabildo eclesiástico y las órdenes religiosas, el cual finalmente tuvo dramáticas consecuencias para ambos. En este artículo se estudia la conflictividad política y eclesiástica a partir de las fuentes coetáneas e historiográficas que narran estos sucesos. Los resultados muestran la compleja naturaleza de las relaciones entre el poder civil y el eclesiástico en las Filipinas de mediados del siglo XVII y los conflictos jurisdiccionales que existían entre las instituciones coloniales en aquel periodo.

Prisión preventiva en la ciudad de México como medio para obtener justicia
Authors: Diez García Javier , Márquez Torres Margarita Jezabel
Published: December 2022

En 2016 entró en vigor el sistema procesal penal acusatorio y oral, con el objetivo de “resolver las contiendas con gran economía de tiempo y recursos”, de una forma eficiente, transparente y humana, en contraposición al sistema inquisitivo, en el que se propiciaba la “opacidad y corrupción, además de ser lento y costoso”. No obstante, los beneficios del nuevo sistema no se han logrado, pues se observa un incremento en las solicitudes de prisión preventiva en la Ciudad de México. Así, dicha medida cautelar se convierte en una regla procesal más que en una excepción.

Chilean Trans Men: Healthcare Needs and Experiences at the Public Health System
Authors: Gonzalez Samantha , Bernales Margarita
Published: December 2022

Introduction: Research shows high rates of discrimination against the transgender population in healthcare centers, which has negative consequences for their quality of life. There are few studies in this area that focus upon the experiences of trans men, although, they tend to experience higher levels of violence and stigmatization in healthcare settings.

Method: We explored the perceptions of 14 Chilean trans men regarding discrimination in healthcare centers from an ethnographic approach, with the aim of analyzing their experiences in these facilities, and identifying their needs in relation to healthcare.

Results: The majority of trans men perceived health centers as a source of discrimination. The most important expressions of discrimination involve questioning their gender identity, and disregarding their social names and pronouns. In view of this, interviewees placed fear of discrimination as the main factor preventing them from being attended at healthcare centers. On the other hand, having access to health workers who are trained in providing care to the transgender population, being provided with information, and the possibility of receiving psychosocial support are the main factors promoting their attendance at these facilities.

Discussion: The study has implications both for health professionals and public policies focused on the transmasculine community. Recommendations are made for professionals and administrative staff to provide respectful and sympathetic care in order to generate spaces free of discrimination that encourage attendance at healthcare centers, improving the welfare of trans men.

Simulating whole atmosphere dynamics, chemistry, and physics is
computationally expensive. It can require high vertical resolution
throughout the middle and upper atmosphere, as well as a comprehensive
chemistry and aerosol scheme coupled to radiation physics. An
unintentional outcome of the development of one of the most
sophisticated and hence computationally expensive model configurations
is that it often excludes a broad community of users with limited
computational resources. Here, we analyze two configurations of the
Community Earth System Model Version 2, Whole Atmosphere Community
Climate Model Version 6 (CESM2(WACCM6)) with simplified “middle
atmosphere” chemistry at nominal 1 and 2 degree horizontal resolutions.
Using observations, a reanalysis, and direct model comparisons, we find
that these configurations generally reproduce the climate, variability,
and climate sensitivity of the 1 degree nominal horizontal resolution
configuration with comprehensive chemistry. While the background
stratospheric aerosol optical depth is elevated in the middle atmosphere
configurations as compared to the comprehensive chemistry configuration,
it is comparable between all configurations during volcanic eruptions.
For any purposes other than those needing an accurate representation of
tropospheric organic chemistry and secondary organic aerosols, these
simplified chemistry configurations deliver reliable simulations of the
whole atmosphere that require 35% to 86% fewer computational resources
at nominal 1 and 2 degree horizontal resolution, respectively.

Published: December 2022

Perifornical hypothalamus (PFH) orexin glucose-inhibited (GI) neurons that facilitate arousal have been implicated in hypoglycemia awareness. Mice lacking orexin exhibit narcolepsy, and orexin mediates the effect of the antinarcolepsy drug modafinil. Thus, hypoglycemia awareness may require a certain level of arousal for awareness of the sympathetic symptoms of hypoglycemia (e.g., tremors, anxiety). Recurrent hypoglycemia (RH) causes hypoglycemia unawareness. We hypothesize that RH impairs the glucose sensitivity of PFH orexin GI neurons and that modafinil normalizes glucose sensitivity of these neurons and restores hypoglycemia awareness after RH. Using patch-clamp recording, we found that RH enhanced glucose inhibition of PFH orexin GI neurons in male mice, thereby blunting activation of these neurons in low-glucose conditions. We then used a modified conditioned place preference behavioral test to demonstrate that modafinil reversed hypoglycemia unawareness in male mice after RH. Similarly, modafinil restored normal glucose sensitivity to PFH orexin GI neurons. We conclude that impaired glucose sensitivity of PFH orexin GI neurons plays a role in hypoglycemia unawareness and that normalizing their glucose sensitivity after RH is associated with restoration of hypoglycemia awareness. This suggests that the glucose sensitivity of PFH orexin GI neurons is a therapeutic target for preventing hypoglycemia unawareness.

Published: December 2022

OBJECTIVE

Childhood adversity has been associated with metabolic syndrome (MetS) and type 2 diabetes risk in adulthood. However, studies have yet to investigate traumatic childhood experiences (TCEs) beyond abuse and neglect (e.g., natural disaster) while considering potential racial/ethnic differences.

RESEARCH DESIGN AND METHODS

To investigate race/ethnicity as a potential modifier of the association between TCEs, MetS, and type 2 diabetes, we used prospectively collected data from 42,173 eligible non-Hispanic White (NHW; 88%), Black/African American (BAA; 7%), and Hispanic/Latina (4%) Sister Study participants (aged 35–74 years) enrolled from 2003 to 2009. A modified Brief Betrayal Trauma Survey captured TCEs. At least three prevalent metabolic abnormalities defined MetS, and self-report of a new diagnosis during the study period defined type 2 diabetes. We used adjusted Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% CIs for type 2 diabetes over a mean ± SD follow-up of 11.1 ± 2.7 years, overall and by race/ethnicity. We also tested for modification and mediation by MetS.

RESULTS

Incident cases of type 2 diabetes were reported (n = 2,479 among NHW, 461 among BAA, and 281 among Latina participants). Reporting any TCEs (50% among NHW, 53% among BAA, and 51% among Latina participants) was associated with a 13% higher risk of type 2 diabetes (HR 1.13; 95% CI 1.04–1.22). Associations were strongest among Latina participants (HR 1.64 [95% CI 1.21–2.22] vs. 1.09 for BAA and NHW). MetS was not a modifier but mediated (indirect effect, HR 1.01 [95% CI 1.00–1.01]; P = 0.02) the overall association.

CONCLUSIONS

TCE and type 2 diabetes associations varied by race/ethnicity and were partially explained by MetS.

Authors: Yen Jia Min , Tang Ning , Tong Shuk In , Chew Effie
Published: December 2022

Objectives: Despite the availability of cancer rehabilitation, utilization at our institution was low. We designed the Cancer Rehabilitation Questionnaire (CRQ) to investigate the prevalence of functional impairments amongst cancer survivors and attitudes towards rehabilitation participation. We evaluated the performance of CRQ as a screening tool for detecting clinically important physical dysfunction.Design: A cross-sectional study was performed, recruiting cancer survivors at a university outpatient oncology clinic. Cancer survivors completed the CRQ and European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire – Core 30 Questionnaires. Descriptive statistical analysis and receiver operator characteristics analysis were performed to assess the ability of the CRQ to detect clinically important physical dysfunction, as measured by the EORTC QLQ-C30.Results: Of 204 participants, 87.3% reported impairments in at least 1 CRQ domain. Pain and weakness were most common. The number of positive items correlated with EORTC global health status and functional scales. A cut-off of ≥ 4 on the CRQ predicted clinically important physical dysfunction (sensitivity 61.8%, specificity 75.5%). Of those with impairments, 53.9% were unwilling to participate in rehabilitation. Transportation, need for caregivers, and cost were the main barriers.Conclusion: Our findings will guide resource allocation to overcome barriers to participation. The CRQ can help to stratify cancer survivors requiring further rehabilitation interventions.
LAY ABSTRACTFunctional impairments due to cancer and its treatment are common, and can be effectively addressed with rehabilitation. To better provide cancer rehabilitation, the Cancer Rehabilitation Questionnaire was designed to investigate what functional problems cancer survivors have and their attitudes towards participation in rehabilitation. We compared the cancer rehabilitation questionnaire with the European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) to see if it could be used as a screening tool for rehabilitation needs. Of 204 participants, 87.3% reported functional impairments in at least 1 Cancer Rehabilitation Questionnaire domain. Pain and weakness were most common. The number of positive Cancer Rehabilitation Questionnaire items correlated with EORTC scales: ≥ 4 positive items in the Cancer Rehabilitation Questionnaire indicated that the number of physical impairments was clinically significant. Among participants with impairments, 53.9% were unwilling to participate in rehabilitation. Transportation, need for caregivers, and cost were cited as barriers. A simple screening tool, such as the Cancer Rehabilitation Questionnaire can help to stratify cancer patients requiring further rehabilitation and intervention.

Few studies exist on the impact of interdisciplinary co-teaching in Higher Music Education. The aim of the present study is to compare and analyse the findings from two pioneer interdisciplinary co-teaching studies involving music/drama and music/physics co-teaching partnerships, conducted independently in Sweden and Ireland. Elements of Vygotskian scholarship informed the theoretical framework and a reflexive and thematic analytic methodology was employed. Four themes emerged similar to those from interdisciplinary scholarship in diverse disciplines. These include: a heightened awareness of subject synergies, problem solving as a catalyst for creativity, new/deeper insights into collaboration and expanded professional identity. In conclusion, didactical implications are addressed, related to potential challenges.

Published: December 2022

Recommender systems play a vital role in the marketing of various goods and services. Despite the intensive growth of the theory of recommendation algorithms and a large number of their implementations, many issues remain unresolved; in particular, scalability, quality of recommendations in conditions of sparse data, and cold start. A modified collaborative filtering algorithm based on data clustering with the dynamic determination of the number of clusters and initial centroids has been developed. Data clustering is performed using the k-means method and is applied to group similar users aimed at increase of the quality of the recommendation results. The number of clusters is calculated dynamically using the silhouette method, the determination of the initial centroids is not random, but relies on the number of clusters. This approach increases the performance of the recommender system and increases the accuracy of recommendations since the search for recommendations will be carried out within one cluster where all elements are already similar. Recommendation algorithms are software-implemented for the movie recommendation system. The software implementation of various methods that allow the user to receive a recommendation for a movie meeting their preferences is carried out: a modified algorithm, memory and neighborhood-based collaborative filtering methods. The results obtained for input data of 100, 500 and 2500 users under typical conditions, data sparsity and cold start were analyzed. The modified algorithm shows the best results – from 35 to 80 percent of recommendations that meet the user's expectations. The drop in the quality of recommendations for the modified algorithm is less than 10 per cent when the number of users increases from 100 to 2500, which indicates a good level of scalability of the developed solution. In the case of sparse data (40 percent of information is missing), the quality of recommendations is 60 percent. A low quality (35 percent) of recommendations was obtained in the case of a cold start – this case needs further investigation. Constructed algorithms can be used in rating recommender systems with the ability to calculate averaged scores for certain attributes. The modified recommendation algorithm is not tied to this subject area and can be integrated into other software systems.
METHOD FOR SYNTHESIZING LOGICAL CLASSIFICATION TREES BASED ON THE SELECTION OF ELEMENTARY FEATURES
Authors:   Uzhhorod National University, Uzhhorod, Ukraine, Povkhan I. F.
Published: December 2022

The general problem of constructing logical recognition and classification trees is considered. The object of this study is logical classification trees. The subject of the research is current methods and algorithms for constructing logical classification trees. The aim of the work is to create a simple and effective method for constructing recognition models based on classification trees for training samples of discrete information, which is characterized by elementary features in the structure of synthesized logical classification trees. A general method for constructing logical classification trees is proposed, which builds a tree structure for a given initial training sample, which consists of a set of elementary features evaluated at each step of building a model for this sample. A method for constructing a logical tree is proposed, the main idea of which is to approximate the initial sample of an arbitrary volume with a set of elementary features. When forming the current vertex of the logical tree, the node provides selection of the most informative, qualitative elementary features from the original set. This approach, when constructing the resulting classification tree, can significantly reduce the size and complexity of the tree, the total number of branches and tiers of the structure, and improve the quality of its subsequent analysis. The proposed method for constructing a logical classification tree makes it possible to build tree-like recognition models for a wide class of problems in the theory of artificial intelligence. The method developed and presented in this paper received a software implementation and was investigated when solving the problem of classifying geological data. The experiments carried out in this paper confirmed the operability of the proposed mathematical support and show the possibility of using it to solve a wide range of practical recognition and classification problems. Prospects for further research may consist in creating a limited method of the logical classification tree, which consists in maintaining a criterion for stopping the procedure for constructing a logical tree according to the depth of the structure, optimizing its software implementations, as well as experimental studies of this method for a wider range of practical tasks.

Published: December 2022

An approach for automating the monitoring and analysis of incoming network traffic in large-scale computer networks is proposed in the paper. The authors suggest using the Linux Berkeley Packet Filter tool to automate traffic analysis in computer networks. The software structure is developed, which includes two main parts: the service machine and the user machine, it is based on the modular principle, which allows for rapid improvement and modernization of the system. The main algorithms for software functionality are built, namely: the algorithm for processing network packets using the Berkeley Packet Filter tool, and the algorithm of the user-space program for loading the Berkeley Packet Filter program to kernel space and setting up communication with it. A study model of program functioning dynamics based on the Petri net theory has been developed. As a result of the application of models based on the Petri net in the software development process, the system works correctly, all states are accessible, and there are no dead ends. A simulation model of the application of the Berkeley Packet Filter tool for the automation of computer network traffic analysis was designed, and the script was created for testing the developed software system. Implemented Python script generates a flow of network packets with random values in the sender IP address, receiver port number, and protocol. These packets, created by the IP address spoofing methodology, later are sent to the service machine's network interface. The developed computer network traffic monitoring software, that uses the Berkeley Packet Filter tool and is implemented in C, C++, and Python programming languages, provides collecting and processing of computer network traffic data. The output of the analysed results is displayed in a user-friendly form. The development and testing of the created software were carried out on the operating system Arch Linux version 5.10.3, which was previously installed on a virtual machine. The results of traffic testing in computer networks in different modes of normal operation and during DDoS attacks are given. In particular, an example of sidebar output with network traffic statistics over a long period, an example of output with network traffic spike parameters, and an example of a warning message, that the sidebar dashboard will show, are presented.

Published: December 2022

The creation of new technologies and their implementation in various fields necessitated Big Data processing and storage. In industrial systems, modernization means the use of a large number of smart devices that perform specialized functions. Data from such devices are used to control the system and automate production processes. A change in the parameters of individual components of the manufacturing system may indicate the need to adjust the global management strategy. The intelligent industrial systems main characteristics were defined in the paper. The Industrial Internet of Things concept and the relevance of the modernization problem for manufacturing were analyzed. The problems of processing Big Data in Industrial Internet of Things systems were examined in the paper. The use of recommendation systems for quickly finding relationships between users and production services was considered. The advantages of Big Data analysis by recommendation systems, which have a favourable effect on industrial enterprise efficiency were given. The use of SVD and FunkSVD matrix factorization algorithms for processing sparse data matrices was analyzed. The possibility of optimizing arrays of information, choosing the most important, and rejecting redundancy with the help of the above algorithms was determined. The proposed algorithms were simulated. The advantages of FunkSVD for working with sparse data were assigned. It was found that the FunkSVD algorithm processes the data in a shorter time than SVD, but this does not affect the accuracy of the result. The SVD is also more difficult to implement and it requires more computing resources was established. It has been shown that FunkSVD uses a lot of data to determine the relationships between it and make recommendations about the products most likely to be of interest to users. To increase the efficiency of processing large sets of information the FunkSVD algorithm was improved in such a way that it uses fewer data to generate recommendations. Based on the results of the research, the modified method works faster than the non-modified one but retains high calculation accuracy, which is important for work in recommender systems. The possibility of providing recommendations to users of industrial systems in a shorter period, thus improving their relevance, was revealed. It was proposed to continue research for finding the optimal parameters of the FunkSVD algorithm for Big Data processing.

In this work, a study of the protective properties of a new hydroxy derivative of chalcone was carried out in comparison with a water-soluble analogue of vitamin E - trolox. The inhibitory activity of the compounds was evaluated on a model system of the long-term process of lipid peroxidation in Siberian sturgeon sperm without and with the addition of a cryo-medium. The prolonged antioxidant activity of chalcone, comparable with the action of the reference compound, was established. An increase in the time of sperm motility in the presence of the compounds under study, while maintaining a survival rate of 100%, allows us to consider the hydroxy derivative of chalcone as an potential cryoprotectant.

Published: December 2022

The paper presents the results of a study of the cryoprotective activity of a new generation of antioxidants – hybrid multifunctional phenolic derivatives during low-temperature preservation of sturgeon reproductive cells. It has been shown that the addition of phosphorus-containing sterically hindered phenol, pyrrolidine and thioacetamide phenolic derivatives to the basic modified Stein cryoprotective medium, makes it possible to increase the low cryoresistance of sturgeon sperm: the level of lipid peroxidation decreases, cell motility improves, and the fertility of defrosted sperm increases. The effectiveness of the cryoprotective action of new antioxidants that can affect different stages and links of oxidative cryostress exceeds the activity of known antioxidants (Ionol and Trolox).

The article presents a study of the genetic diversity of the Russian sturgeon (Acipenser gueldenstaedtii) of the brood stock (RMS) of the Donskoy sturgeon hatchery (DOZ) using the analysis of microsatellite nuclear markers. In the course of the study, a general decrease in the heterozygosity of the population for four of the five loci studied was established, and in the study of the RMS population over the past two years, rare groups of alleles were identified that were not found in the sample for 2014. The data obtained can be used by the plant when drawing up crossbreeding schemes to preserve the overall allelic (genetic) diversity of the population.
