Mitigation of Power Unbalance in Electrical Distribution Transformers with Solar Photovoltaic Panels
Authors: Bozavlı Umut , Yılmaz Mehmet , Corapsiz Muhammedfatih
Published: May 2024

In this article, a design is proposed to improve the power unbalance between the phases of three-phase electricity distribution transformers with the help of photovoltaic (PV) solar panels to be mounted on the roof of transformer centers. Simulation studies of the design were performed via MATLAB/Simulink and simulation results were observed and compared with real-time phase current data from four transformer centers. In the Transfer Switcher and Control System (TSCS) algorithm developed in the design, the percentage current unbalance rate (PCUR%) of the transformer is determined and the power produced from the PV panels is injected into the appropriate phase of the transformer. Phase lock loop (PLL) is used to ensure this connection occurs smoothly. In this study, performance analysis was made based on simulation results for the phase unbalance seen in the transformer before TSCS was activated and for the phase unbalance seen in the transformer after TSCS was activated. In simulation studies conducted on real-time data taken from a total of four transformers in Erzurum, Ağrı and Erzincan provinces, it was seen that the proposed approach had a reducing effect on the power unbalance in the transformer. In addition, approximately 3.6 kW of additional energy is provided to the distribution system for each transformer. In addition, it has been observed that the average current values drawn from the transformers has also decreased.

Published: May 2024

This study primarily discusses the influence of internal structure on the performance of sludge concentrators. The focus is to evaluate the influence of internal structural changes on the improvement of sludge settling and clarifying efficiency through numerical simulation, so as to achieve the optimal design of sludge settling equipment parameters. The results show that with the increase of the bottom outlet width of the cone guide blade, the turbulence decreases, and the sludge thickening efficiency is significantly increased by about 27.1%, from 0.01036 at 300 mm to 0.0132 at 500 mm, which significantly improves the sludge settling and thickening efficiency. Also, the addition of the extended deflector significantly increased the bottom sludge settling concentration from 0.0129 to 0.0134 by about 3.87% and reduced the outlet suspended matter by about 13.6%. Obviously, the influence of effluent width and extended diversion length on sludge settling efficiency and water purification cannot be ignored. Therefore, an optimal design that takes into account the outlet width and the length of the extended deflector is critical to achieve optimal sludge concentration and water quality in the sludge concentrator. These findings provide numerical theoretical insights for improving the performance of sludge thickeners and the efficiency of water treatment.
Area prioritising criteria during phased conversion from intermittent to continuous water supply: The case study of Lusaka Water Supply and Sanitation Company, Zambia
Authors: Ncube Theodorah Tania , Nyirenda Edwin , Simukonda Kondwani , Farmani Raziyeh
Published: May 2024

Conversion from intermittent to continuous water supply is a recommended approach for improving water supply service to communities. The conversion process is complex and requires huge financial and human resources investments. Because such resources are always limited and cannot be adequately provided at once, phased conversion is encouraged. However, there are challenges with this approach in terms of which areas should be prioritized during the conversion process so that the water supply situation for the unconverted areas is not aggravated. This article uses a questionnaire and semi-structured interviews to identify the criteria for prioritising areas to be converted during phased conversion to continuous water supply from a water utility perspective. The Lusaka Water Supply and Sanitation Company is used as a case study. Results show that the financial sustainability of the utility company is the major criterion for selecting an area to be prioritized. In countries like Zambia where tariff structures are such that industries subsidise domestic water consumption and the affluent subsidise water consumed by the poor, prioritising financial sustainability entails giving priority to areas where high revenues are expected. This is synonymous with giving priority to the affluent or the middle-class areas with high densities of water consumers.
Spatiotemporal dynamic of soil erosion in the Roraya River Basin based on RUSLE model and Google Earth Engine
Authors: Aldiansyah Septianto , Wardani Farida
Published: May 2024

The Roraya River Basin is an important water conservation area in Sulawesi. The soil erosion status in this study was investigated using Revised Universal Soil Loss Equation (RUSLE) on Google Earth Engine (GEE). Soil erosion modulus, a characteristic of the spatiotemporal variation of soil erosion intensity, is calculated and analyzed from various multi-source data. The research results show that (1) the average soil erosion modulus in the Roraya River Basin in 2001–2021 was 307.22 t · h−1 · year−1. This shows that around 25% of the Roraya River Basin requires soil protection measures as the region faces a significant risk of erosion; (2) the trend in the range of soil erosion in the Roraya River Basin in 2001–2021 tends to vary, initially stable, then decreases and increases significantly with increasing altitude and slope (western plateau). A striking trend occurs in various classes of vegetation cover and rainfall erosivity where the increase in soil erosion is caused by both and this applies in reverse, thus encouraging the dynamic development of soil erosion: (3) RUSLE model integrated into GEE can handle vegetation cover factors and conservation measure factors. This is a reliable soil erosion monitoring tool on a wide scale.
Development of a spatial projection map of glacial retreat based on vulnerability maps in the Central Cordillera, Peru
Authors: Arias Alonso , Núñez Nicolás , Rau Pedro , Venail Patrick
Published: May 2024

Increase in average global temperature over the last few decades has caused an accelerated retreat of tropical glaciers. Andean populations live in strict dependence on the water services provided by mountains and glaciers. The present study aims to generate a glacier melt projection map in the Peruvian Central Cordillera based on vulnerability maps over the 1990–2021 period. Seven satellite images were selected to determine the changes in glacier coverage based on normalized indexes. Subsequently, seven parametric maps consisting of terrain and climate characteristics were assimilated into a vulnerability analysis based on the frequency index and the Shannon entropy index model, allowing one to identify areas most susceptible to glacial retreat. The results show that the most important criteria for the southern and northern glacial study areas are surface temperature, elevation, precipitation, aspect, orientation, and slope. The validation results revealed the most accurate set of parameters from the vulnerability map in terms of projecting melting areas and were used to produce a spatial projection map for the period 2021–2055. From 2021, a glacier loss in the range 84–98% would be reached by the 2050s.
A combinatorial method of small sample identification
Authors: Volovik A. V.
Published: May 2024

Aim. For the purpose of improving the reliability of decisions regarding the uniformity of distributions over samples of limited size, a combinatorial method has been developed for defining a criterion based on simple combinations of sample values. Methods. The paper uses methods of the probability theory, mathematical statistics, and combinatorics. Results. The proposed criterion is highly efficient for distinguishing small samples when testing statistically similar hypotheses, such as the hypothesis of a uniform distribution law and the hypothesis of a beta distribution of the first kind. Conclusions. The approach proposed in the paper enables a sequential analysis procedure (detection of process “imbalance”). This procedure makes it possible to reliably detect the “imbalance” (deviation of the distribution of observations from the uniform law) of a process with a practically sufficient intensity using recurrent relations.

2-Thioxoimidazolidin-4-one derivatives 3, 4, 7, 8, and 9 have been synthesized from 3-
(benzylideneamino)-2-thioxoimidazolidin-4-one (2) as a starting material. Compounds 3, 4, 7, 8, and 9 were
obtained via the reaction of compound (2) with ethyl chloroacetate, methyl acrylate, and chlorophenacyl bromide,
respectively. Elemental analysis and several spectroscopy techniques were used to confirm the synthesized
compounds. The synthesized compounds, particularly compounds 7 and 8, exhibited significant cytotoxic
influences on MCF-7 cells, surpassing staurosporine. Compounds 7 and 8 can induce apoptosis in those treated
MCF-7 cells. Studying molecular docking approved that compounds 7 and 8 bind in two and three dimensions
to the aromatase binding pockets. Molecular modeling indicates compounds 7 and 8 have a strong affinity for
human topoisomerase II beta, establishing its promise as a multifaceted antitumor agent for breast cancer.

Flow assurance encompasses the technical challenges of transporting hydrocarbon
mixtures from the reservoir to the platform and refineries. Challenges in flow assurance
include gas hydrate plugs, deposition of paraffin wax, asphaltenes, naphthenates, scale, and
corrosion. Managing these deposits incurs high costs due to production interruptions and
remediation operations like pigging, solvent injection, acid dissolutions, and thermal treatments.
Therefore, prevention methods, such as the use of chemicals that inhibit deposit
formation, are preferred. This review consolidates scientific works highlighting the role of
carboxylic acids in the synthesis of chemicals for addressing flow assurance challenges as
starting materials or final products for direct use. These organic compounds are already
employed for the mild remediation of scale and naphthenate deposits and inhibiting gas
hydrate, paraffin wax, asphaltene, scale deposits, and corrosion. Moreover, they play a crucial role in developing
green flow assurance challenges inhibitors, given that some, like fatty acids, amino acids, and aromatic carboxylic
acids, can be derived from natural sources. The presence of the carboxylic acid group in polymers and biopolymers
is also essential for the effectiveness of these products as inhibitors. The literature further suggests
that carboxylic acids will play a key role in the future development of simultaneous gas hydrate, corrosion, and
scale inhibitors.

Authors: Almomani Jumana , Abdel Razeq Nadin M. , Khalaf Inaam
Published: May 2024

Background

Home care of late preterm infants (LPIs) can be challenging for mothers after hospital discharge because they are more vulnerable than full-term infants and experience higher hospital admission rates.

Purpose

This study aims to determine the effect of a thorough and collaborative discharge education program offered by a nurse to mothers of LPIs. The program focuses on the mother’s preparedness (self-efficacy and readiness) to care for their LPIs at home after discharge from the neonatal intensive care unit.

Methods

A quasi-experimental design will be applied in a large, accredited referral NICU in Jordan. Two groups of mothers will be enrolled using convenience sampling. The experimental group will receive the designed pre-discharge education, and the comparison group will receive routine discharge instructions for LPI care at home. The outcome will measure a mother’s self-efficacy and readiness to care for their LPI at home. Data will be compared within and between the groups before and after the intervention. An independent and paired sample t-test will be used for analysis.

Results/Discussion

This study will be conducted on the notion that educating mothers is a principal role for neonatal nurses and helps improve the quality of healthcare services provided to parents of vulnerable infants.

Implications for Nursing

The study findings will provide insight into national and global neonatal nursing practices through a thorough discharge education program for mothers with LPIs.

Conclusion

Publishing a research protocol encourages research transparency and allows the exchange of methodological insights and feedback between academic and clinical communities.
relationship between anemia and pneumonia severity in children aged 29 days to 5 years
Authors: Simanjuntak Stevan Pagar Pardamean , Saragih Japendi Rizal Pavliando
Published: May 2024

Background: Pneumonia is an acute infection of the lung parenchyma and is a leading cause of death among children under five worldwide. The World Health Organization (WHO) notes that 15% of all under-five deaths are due to pneumonia, with a prevalence of 3.55% in Indonesia. Anemia, especially iron deficiency anemia, is also a common health issue among children and is associated with increased morbidity and mortality. Anemia is believed to increase the risk and worsen the severity of pneumonia due to hypoxia and impaired immune function. Methods: This cross-sectional study was conducted at Waikabubak General Hospital, West Sumba, on children aged 29 days to 5 years who were hospitalized with pneumonia from January 2022 to December 2023. Pneumonia was defined based on WHO criteria. Anemia was defined as blood hemoglobin levels <11 mg/dL. Exclusion criteria included other conditions that might affect the study results. Data analysis was performed using the Chi-square test to assess the relationship between anemia and pneumonia severity. Results: Of the 399 subjects meeting the criteria, 57.9% were male and 42.1% female. A total of 61.9% were diagnosed with mild to moderate pneumonia, and 38.1% were diagnosed with severe pneumonia. Most subjects (55.8%) had anemia.

A literatura na formação docente e a catarse como fundamento preparatório para a sala de aula
Authors: Ceribeli Maria Cláudia Bachion
Published: May 2024

O artigo propõe fundamentar a necessidade de a catarse se realizar com o professor, visto que, antes de se tornar docente, ocupa o espaço de discente na Universidade. A pesquisa não se refere à catarse como um único momento, pelo contrário, defende-a como processo que deve ser constante nos estudos, nas leituras e nas pesquisas que permeiam a formação docente durante os estudos de graduação e os demais processos de construção do conhecimento que fazem parte do aperfeiçoamento docente. A abordagem, fundamentada nos pressupostos teóricos da pedagogia histórico-crítica, sugere que a literatura, na formação docente, pode contribuir para promover o processo catártico, preparando o sujeito para a sistematização e para a mediação do conhecimento, bem como a sua humanização; reforça que o acesso à arte e à literatura é um direito de todos e não para poucos e defende uma utilização de métodos de análise da obra literária que não se restringem ao aspecto linguístico. Amparada nos textos de Newton Duarte, Antonio Candido e Demerval Saviani, a pesquisa sugere métodos que incluam uma abordagem sociológica, histórica, cultural, filosófica e artística, permitindo uma compreensão e apreensão da obra literária de caráter multidisciplinar e entrelaçando saberes de forma a eliminar a separação de conteúdos em “caixinhas”. Observa-se que docentes que não atravessam experiências catárticas durante os seus estudos formativos não dispõem de elementos para conduzir outros sujeitos pelas referidas experiências – os futuros alunos. Conclui-se que a formação docente sob essa perspectiva possibilita oferecer instrumentos para a transformação dos sujeitos envolvidos no processo educacional, preparando-os para implementar uma sociedade igualitária.

Liberating Minds: The Intellectual Legacy of Angela Davis and Its Images in Film
Authors: Sales Michelle , Muniz Bruno
Published: May 2024

We propose thinking of Angela Davis's intellectual legacy from a decolonial perspective. We point out that just as the fight for civil rights and the end of racial segregation in the United States helped to consolidate the Black movement in Brazil, the circulation of anti-colonial ideas during the struggles for the decolonization of African countries in the 1950s and 60s was crucial to the circulation of abolitionist ideas and anti-racist movements in the United States and abroad. We will analyze interchanges capable of pointing out "the recognition of multiple and heterogeneous colonial differences, as well as the multiple and heterogeneous reactions of populations and subjects subordinated to the coloniality of power" (Bernardino-Costa & Grosfoguel, 2016, p. 21). Our contribution seeks to analyze Davis as a public and militant intellectual through her images in film. Beyond considering Angela Davis's image in cinema as representation, we also analyze how her intellectual and political activities were involved with the flourishing of a new Black cinema in the United States. This paper analyzes films such as Child of Resistance (1973), Free Angela and All Political Prisoners (2015), and 13th (2016).

Collaborations as an Innovative Marketing Tool
Authors: Polzunova N. N. , Ryabova D. O.
Published: May 2024

Relevance. At the present stage of economic development, collaborations are gaining relevance, which are considered as a marketing and social tool. In 2023, this is a real trend both among local brands and among brands with a global level. This is a way to stand out from the competition and promote a product or service unobtrusively and creatively. Also, the popularity of this tool is added by the lack of binding to any of the types of marketing. It can be argued that collaboration is characterized by universality.

The purpose of this topic is to determine the conditions for creating a successful collaboration. 

Objectives. To achieve it, the tasks are set: to consider the concept of collaboration as an innovative tool, the history of its appearance as a marketing tool, the differences between collaborations and affiliate marketing, types of collaborations, successful and unsuccessful cases, to analyze the successful collaboration of the Laviani Cosmetology and Natural Beauty Center and the Twine Fitness and Stretching studio Shpagetty

Methodology. The main research methods used were theoretical – the study of statistical data, research conducted in this area, theoretical training materials on the topic under consideration, practical experience in conducting such campaigns – and empirical – conducting a collaboration and its analysis after completion.

Results. As a result, the rules for organizing a successful collaboration were derived and a conclusion was made about the capabilities of the marketing tool in question. 

Conclusions. Collaborations are an innovative way to attract a new audience, the essence of which is the creative presentation of a fundamentally new product, which is the result of cooperation between two companies with the same values. Despite the long history, collaborations in the form in which they exist now can be called an innovative marketing tool.
The Economic Aspect of the Importance of a Balanced Diet: Reducing the Burden On Healthcare
Authors: Masterova S. N.
Published: May 2024

Relevance. The study of a balanced diet of the population is relevant at the present time, since a healthy diet is one of the key factors affecting human health and preventing the development of many diseases. It is also important to maintain optimal physical and mental health, increase productivity and improve quality of life. Malnutrition and obesity increase health care costs because more resources are needed to treat related diseases. This puts pressure on health budgets and may worsen the availability of medical care for other patients.

The purpose of the study is to assess the economic aspect of the importance of a balanced diet.Objectives 

Objectives: to study the essence and main criteria of a balanced diet; to identify health problems associated with an unbalanced diet of the population; to consider the increase in the number of obese patients as a health problem.

Methodology. The methodological basis of the study was the idea that there is a connection between a balanced diet of the population and the burden on the country's health care. 

Results. The analysis carried out in the work showed that malnutrition and obesity increase health care costs, since more resources are needed to treat diseases related to these problems. This puts pressure on health budgets and may worsen the availability of medical care for other patients. 

Conclusions. A balanced diet can lead to lower health care costs by reducing the risk of developing chronic diseases such as obesity, cardiovascular disease and diabetes. This can lead to lower healthcare costs for individuals and society as a whole. In addition, a balanced diet can increase productivity and reduce absenteeism in the workplace. When people eat right, they are less prone to fatigue, illness and other diseases that can affect their ability to work effectively. This can lead to increased productivity and economic growth.
Medical Information Protection in Internet Hospital Apps in China: Scale Development and Content Analysis
Authors: Jiang Jiayi , Zheng Zexing
Published: May 2024

Background

Hospital apps are increasingly being adopted in many countries, especially since the start of the COVID-19 pandemic. Web-based hospitals can provide valuable medical services and enhanced accessibility. However, increasing concerns about personal information (PI) and strict legal compliance requirements necessitate privacy assessments for these platforms. Guided by the theory of contextual integrity, this study investigates the regulatory compliance of privacy policies for internet hospital apps in the mainland of China.

Objective

In this paper, we aim to evaluate the regulatory compliance of privacy policies of internet hospital apps in the mainland of China and offer recommendations for improvement.

Methods

We obtained 59 internet hospital apps on November 7, 2023, and reviewed 52 privacy policies available between November 8 and 23, 2023. We developed a 3-level indicator scale based on the information processing activities, as stipulated in relevant regulations. The scale comprised 7 level-1 indicators, 26 level-2 indicators, and 70 level-3 indicators.

Results

The mean compliance score of the 52 assessed apps was 73/100 (SD 22.4%), revealing a varied spectrum of compliance. Sensitive PI protection compliance (mean 73.9%, SD 24.2%) lagged behind general PI protection (mean 90.4%, SD 14.7%), with only 12 apps requiring separate consent for processing sensitive PI (mean 73.9%, SD 24.2%). Although most apps (n=41, 79%) committed to supervising subcontractors, only a quarter (n=13, 25%) required users’ explicit consent for subcontracting activities. Concerning PI storage security (mean 71.2%, SD 29.3%) and incident management (mean 71.8%, SD 36.6%), half of the assessed apps (n=27, 52%) committed to bear corresponding legal responsibility, whereas fewer than half (n=24, 46%) specified the security level obtained. Most privacy policies stated the PI retention period (n=40, 77%) and instances of PI deletion or anonymization (n=41, 79%), but fewer (n=20, 38.5%) committed to prompt third-party PI deletion. Most apps delineated various individual rights, but only a fraction addressed the rights to obtain copies (n=22, 42%) or to refuse advertisement based on automated decision-making (n=13, 25%). Significant deficiencies remained in regular compliance audits (mean 11.5%, SD 37.8%), impact assessments (mean 13.5%, SD 15.2%), and PI officer disclosure (mean 48.1%, SD 49.3%).

Conclusions

Our analysis revealed both strengths and significant shortcomings in the compliance of internet hospital apps’ privacy policies with relevant regulations. As China continues to implement internet hospital apps, it should ensure the informed consent of users for PI processing activities, enhance compliance levels of relevant privacy policies, and fortify PI protection enforcement across the information processing stages.
Shifting Grounds—Facilitating Self-Care in Testing for Sexually Transmitted Infections Through the Use of Self-Test Technology: Qualitative Study
Authors: Trettin Bettina , Skjøth Mette Maria , Munk Nadja Trier , Vestergaard Tine , Nielsen Charlotte
Published: May 2024

Background

Chlamydia remains prevalent worldwide and is considered a global public health problem. However, testing rates among young sexually active people remain low. Effective clinical management relies on screening asymptomatic patients. However, attending face-to-face consultations of testing for sexually transmitted infections is associated with stigmatization and anxiety. Self-testing technology (STT) allows patients to test themselves for chlamydia and gonorrhea without the presence of health care professionals. This may result in wider access to testing and increase testing uptake. Therefore, the sexual health clinic at Odense University Hospital has designed and developed a technology that allows patients to get tested at the clinic through self-collected sampling without a face-to-face consultation.

Objective

This study aimed to (1) pilot-test STT used in clinical practice and (2) investigate the experiences of patients who have completed a self-test for chlamydia and gonorrhea.

Methods

The study was conducted as a qualitative study inspired by the methodology of participatory design. Ethnographic methods were applied in the feasibility study and the data analyzed were inspired by the action research spiral in iterative processes using steps, such as plan, act, observe, and reflect. The qualitative evaluation study used semistructured interviews and data were analyzed using a qualitative 3-level analytical model.

Results

The findings from the feasibility study, such as lack of signposting and adequate information, led to the final modifications of the self-test technology and made it possible to implement it in clinical practice. The qualitative evaluation study found that self-testing was seen as more appealing than testing at a face-to-face consultation because it was an easy solution that both saved time and allowed for the freedom to plan the visit independently. Security was experienced when the instructions balanced between being detail-oriented while also being simple and illustrative. The anonymity and discretion contributed to preserving privacy and removed the fear of an awkward conversation or being judged by health care professionals thus leading to the reduction of intrusive feelings.

Conclusions

Accessible health care services are crucial in preventing and reducing the impact of sexually transmitted infections and STT may have the potential to increase testing uptake as it takes into account some of the barriers that exist. The pilot test and evaluation have resulted in a fully functioning implementation of STT in clinical practice.

Authors: Palmeirim Marta S , Houngbedji Clarisse A , Barth-Jaeggi Tanja , Kouamé Jean-Pierre Y , Krouman Aboubakar , Coulibaly Daouda , Wyss Kaspar
Published: May 2024

Background

Accurate and timely infectious disease surveillance is pivotal for effective public health responses. An important component of this is the disease surveillance tools used. Understanding views and experiences of users is crucial for informing policy decisions and ensuring the seamless functioning of surveillance systems.

Objective

In this study, we aimed to assess the user perceptions of 3 disease surveillance tools used in Côte d’Ivoire, namely, MAGPI, District Health Information Software 2 (DHIS2), and Surveillance Outbreak Response Management and Analysis System (SORMAS), the latter was implemented in 2021 within a pilot scheme.

Methods

We conducted interviews and a web-based survey distributed to users of the 3 surveillance tools. The survey assessed users’ views of the surveillance tools’ usefulness, ease of use, feelings toward the tool, conditions that may influence the use, and other characteristics. The descriptive analysis compared responses from SORMAS, MAGPI, and DHIS2 users, providing a comprehensive evaluation of their experiences.

Results

Among the 159 respondents who actively use one of the systems, MAGPI was the most widely used surveillance tool among respondents (n=127, 79.9%), followed by DHIS2 (n=108, 67.9%), and SORMAS (n=25, 15.7%). In terms of users’ perceptions, SORMAS, despite its limited implementation, emerged as a tool that allows for data analysis and had the most comprehensive set of functionalities. DHIS2 was appreciated for its frequency of report provision, although users reported occasional IT system failures. MAGPI was recognized for its ease of use but was reported to lack certain functionalities offered by the other surveillance systems.

Conclusions

This study offers valuable insights into the perceptions of disease surveillance tools users in Côte d’Ivoire. While all systems were positively regarded, each exhibited strengths and weaknesses addressing different needs and functionalities. Policy makers and health officials can use these findings to enhance existing tools or consider a unified approach for infectious disease surveillance systems. Understanding users’ perspectives allows them to optimize the choice of surveillance tools, ultimately strengthening public health responses in Côte d’Ivoire and potentially serving as a model for other countries facing similar decisions in their health care systems.

Siguiendo el modelo teórico propuesto por Kaztman (1999) este documento construye un índice para explorar la vulnerabilidad social para adolescentes y jóvenes de Santiago de Cali, con datos de las y los participantes del programa TIP - JSF Jóvenes sin Fronteras, cuyas condiciones de vida están determinadas por la precariedad, la exclusión social y económica, y en especial, por hacer parte de la población de estratos socioeconómicos bajos (1 y 2) que, además, tienen una mayor exposición a la violencia. Al aplicar un Índice de Vulnerabilidad Juvenil a los participantes entre los 11 y 24 años, se encontró que la gran mayoría presenta algún tipo de vulnerabilidad, registrando carencias en indicadores como el acceso a servicios públicos y asistencia escolar.
Producción alimentaria y población en el contexto de crisis sanitaria: el caso de México y la entidad mexiquense 1980-2021
Authors: González-Bejarano Diego Abelardo
Published: May 2024

Analizar los factores que inciden en la crisis en la producción de alimentos en México en los últimos 41 años y el crecimiento demográfico el cual ejerce una presión sobre la producción de alimentos, así como de su demanda tanto nacional y la entidad mexiquense. También se exponen brevemente el tema del abastecimiento nacional, las características de la producción de los distritos rurales de la entidad mexiquenses así como de la pobreza y carencia alimenticia del Estado de México en los años recientes. Con base en fuentes secundarias se ha comprobado el desequilibrio alimentario, así como el crecimiento poblacional del país y por ende el de la entidad, la cual ha sido acompañada por las crisis económicas agrícolas, el cambio climático e incluso la pandemia o inseguridad que conducen a la carencia de alimentos. Apoyándose en los modelos en modelos de regresión simple, múltiple, correlación y tasas de crecimiento, que brindan el soporte argumentativo de esta investigación en función de la relación que existe entre la producción de alimentos y la población. Todo ello en el contexto del denominado modelo de desarrollo neoliberal hasta llegar al año del COVID-19, la caída de los precios de los commodities, la guerra entre Rusia y Ucrania en 2022.
Revisión de la epidemiología y factores de riesgo de la obesidad infantil

Desde el 2006, México ha ocupado el primer lugar en obesidad infantil, esto siendo reportado por la ENSANUT, siendo el indicativo principal el 34% de niños en edades de preescolar y escolares, los cuales estaban entre el sobrepeso y la obesidad, siendo desde entonces que se ha puesto un énfasis en la prevención de esta enfermedad; de manera errónea, se ha planteado que el problema es únicamente individual en anteriores generaciones, siendo el estado de salud una elección individual, cuando esto se torna valido únicamente cuando el entorno de la persona resulta favorable. Esto no sucede en la mayoría de la población mexicana, ya que los factores ambientales, genéticos, sociales y entre otros, también influyen en la percepción de esta problemática. Así mismo, se ha mostrado una incidencia y prevalencia elevadas, ya que no hay una corrección de los factores modificables dentro de la sociedad y posteriormente del individuo.

Abstract: Post-operative rehabilitation is critical in orthopedic surgery, especially for hip joint surgeries. Traditional therapies like manual exercises and resource limits in rehabilitation centers might be tough, but early mobilization and rehabilitation are critical for regaining joint function and allowing patient return to normal activities. Continuously Passive Motion (CPM) devices, primarily developed for knee joint rehabilitation, offer a non-invasive method for passive joint mobility, restoring joint range of motion and lowering post-operative stiffness risk. Their application in hip joint healing is gaining pace, offering better results and increased patient satisfaction. The research also investigates abduction mobility in the hip joint, which is necessary for daily actions like stepping to the side, getting out of bed, or exiting a car. Understanding hip joint biomechanics and range of motion parameters is vital for establishing efficient rehabilitation approaches. By merging clinical insights with technology innovations, this research intends to optimize post-surgery rehabilitation regimens, enhancing patient outcomes and quality of life. The subject of orthopedic rehabilitation continues to expand through interdisciplinary collaboration and innovation, bringing new choices for enhancing patient care and recovery trajectories.

Abstract: This paper describes the design, manufacture and performance evaluation of a small modified forage cutter and harvester built with a very simple mechanism that is cheap and simple. Harvesting fodder is a necessary farming activity that requires considerable work. Labor costs and availability pose significant challenges during the cutting season. Due to shortage of labor and unpredictable weather during harvesting, farmers must use mechanized methods to ensure speed of harvesting and collection. We have used various techniques to analyze and design a very low-cost fodder cutter and harvester with solar system and battery. This machine is designed for small farmers who have less than 2 acres of agricultural land. This small machine can cut up to two stacks of fodder at once. The feed is cut by reciprocating blades that cut it like scissors. It uses a 12V electric motor for propulsion. This power is supplied to the cutter by an electric motor. After sowing, the feed is collected in a storage tank using a collection system. Because it was built using spare parts readily available in the area, this small machine is easy to maintain and operate. Small farmers can find this machine the answer to their labor and implementation cost problems
Resource Marginal Problems

We introduce the resource marginal problems, which concern the possibility of having a resource-free target subsystem compatible with a given collection of marginal density matrices. By identifying an appropriate choice of resource R and target subsystem T, our problems reduce, respectively, to the well-known marginal problems for quantum states and the problem of determining if a given quantum system is a resource. More generally, we say that a set of marginal states is resource-free incompatible with a target subsystem T if all global states compatible with this set must result in a resourceful state in T of type R. We show that this incompatibility induces a resource theory that can be quantified by a monotone and obtain necessary and sufficient conditions for this monotone to be computable as a conic program with finite optimum. We further show, via the corresponding witnesses, that (1) resource-free incompatibility is equivalent to an operational advantage in some channel-discrimination tasks, and (2) some specific cases of such tasks fully characterize the convertibility between marginal density matrices exhibiting resource-free incompatibility. Through our framework, one sees a clear connection between any marginal problem – which implicitly involves some notion of incompatibility – for quantum states and a resource theory for quantum states. We also establish a close connection between the physical relevance of resource marginal problems and the ground state properties of certain many-body Hamiltonians. In terms of application, the universality of our framework leads, for example, to a further quantitative understanding of the incompatibility associated with the recently-proposed entanglement marginal problems and entanglement transitivity problems.
DIREITO A CIDADE CONTRADIÇÕES ACERCA DA REALIDADE URBANA

Published: May 2024

O presente artigo tem como objetivo analisar a cidade como totalidade a partir do pensamento do sociólogo francês Henri Lefebvre que em seu investimento teórico busca compreender as contradições existentes que fazem parte dos espaços urbanos da sociedade capitalista. A totalidade aqui é vista na perspectiva do materialismo histórico dialético que afirma a realidade como síntese de múltiplas determinações. Dessa forma, o artigo pretende empreender uma discussão teórico-metodológica acerca da cidade e os seus espaços em meio às contradições existentes nos espaços urbanos.
