The discovery of extreme magnetoresistance (XMR) in non-magnetic materials attracted attention to the WTe2 semimetal. We have carried out studies of magnetoresistance in a tungsten ditelluride single crystal in the magnetic field range up to 14 T. Magnetoresistance increased with increasing field following a near quadratic law without saturation. The Shubnikov-de Haas oscillations were observed. Four fundamental frequencies were found in the oscillations spectrum, which correspond to two electron and two hole pockets caused by strong spin-orbit coupling.

Published: September 2021

Based on the study of photoconductivity in GaAs / AlAs p-i-n heterostructures in the visible light range, the dominant role of the diffusion channel of photoexcited electrons from heavily doped layers in the formation of photocurrent oscillations from the bias voltage and the determining contribution of this channel to the total current through the structure is shown. A qualitative model of the transport of excited carriers is considered, which assumes the diffusion channel as the main source of photooscillations.

The structure, optical and magneto-optical properties of colloidal solutions of iron oxide nanoparticles obtained by pulsed ablation in distilled water, both without additives and with various functional additives: gold-hydrochloric acid, silicon oxide, and polyvinylpyrrolidone, have been studied. It is shown that the main magnetic phase is magnetite Fe3O4. The size distribution of nanoparticles and the degree of their agglomeration depend on the additives. In the absence of the latter, a very wide of size distributions and strong agglomeration of particles are observed. The narrowest distribution curve with a maximum corresponding to ~ 7 nm and an almost complete absence of agglomeration are observed for particles synthesized in the presence of polyvinylpyrrolidone. The shape of the spectral dependence of magnetic circular dichroism, which generally corresponds to the spectrum of magnetite, undergoes some modifications for various additives, which is associated with defects in the distribution of iron ions between different positions in the crystal.

The features of spin-wave transport in a system of coupled magnetic microwaveguides with perpendicular magnetization relative to the longitudinal axis of the system are considered. In this case, the system has uniaxial anisotropy, the horizontal and vertical coupling coefficients have different signs, and the isofrequency surfaces have a "saddle" shape. In the propagation of transversely limited beams of spin waves, the type of curvature of the wave fronts is determined by the direction of wave propagation relative to the external magnetic field.
Механизм обусловленного динамической примесной подсистемой аномального поведения пластического течения материалов с высоким кристаллическим рельефом
Authors: Петухов Б.В.
Published: September 2021

A model of dynamic interaction of dislocations with an impurity subsystem of crystals with a high potential relief of the crystal lattice (Peierls barriers) is developed. Such materials include metals with body-centered cubic structure, semiconductors, ceramics, and many others. It is shown that the modification of impurity migration barriers near the dislocation core significantly affects the segregation of impurities on the moving dislocation. The presence of a substantially nonequilibrium initial stage of segregation kinetics leading to anomalies of dislocation dynamics and yield strength of materials is substantiated.
Mobile Health Apps for Pregnant Women: Systematic Search, Evaluation, and Analysis of Features
Authors: Frid Gabriela , Bogaert Kelly , Chen Katherine T
Published: September 2021

Background

Many pregnant women use the internet to obtain information about pregnancy and childbirth. Over 50% of pregnant women use pregnancy apps and must search through thousands of pregnancy or women’s health–related apps available on app stores. The COVID-19 pandemic is changing how women receive prenatal care. Mobile health apps may help maintain women’s satisfaction with their prenatal care.

Objective

Our objective is to identify pregnancy mobile apps and to evaluate the apps using a modified APPLICATIONS (app comprehensiveness, price, privacy, literature used, in-app purchases, connectivity, advertisements, text search field, images/videos, other special features, navigation ease, subjective presentation) scoring system.

Methods

A list of pregnancy apps was identified in the first 20 Google search results using the search term “pregnancy app.” After excluding irrelevant, inaccurate, malfunctioning, or no longer available apps, all unique apps were downloaded and evaluated with the modified APPLICATIONS scoring system, which includes both objective and subjective criteria and evaluation of special features.

Results

A list of 57 unique pregnancy apps was generated. After 28 apps were excluded, the remaining 29 apps were evaluated, with a mean score of 9.4 points out of a maximum of 16. The highest scoring app scored 15 points. Over 60% (18/29) of apps did not have comprehensive information for every stage of pregnancy or did not contain all four desired components of pregnancy apps: health promotion/patient education, communication, health tracking, and notifications and reminders. Only 24% (7/29) of apps included a text search field, and only 28% (8/29) of apps cited literature.

Conclusions

Our search yielded many high-scoring apps, but few contained all desired components and features. This list of identified and rated apps can lessen the burden on pregnant women and providers to find available apps on their own. Although health care providers should continue to vet apps before recommending them to patients, these findings also highlight that a Google search is a successful way for patients and providers to find useful and comprehensive pregnancy apps.

Authors: Rabbani Md Golam , Akter Orin , Hasan Md Zahid , Samad Nandeeta , Mahmood Shehrin Shaila , Joarder Taufique
Published: September 2021

Background

The world has been grappling with the COVID-19 pandemic, a dire public health crisis, since December 2019. Preventive and control measures have been adopted to reduce the spread of COVID-19. To date, the public’s knowledge, attitudes, and practices regarding COVID-19 across Bangladesh have been poorly understood. Therefore, it is important to assess people’s knowledge, attitudes, and practices (KAP) toward the disease and suggest appropriate strategies to combat COVID-19 effectively.

Objective

This study aimed to assess the KAP of Bangladeshi people toward COVID-19 and to identify their determinants.

Methods

We conducted a country-wide cross-sectional telephonic survey from May 7 to 29, 2020. A purposive sampling method was applied, and adult Bangladeshi citizens who have mobile phones were approached to participate in the survey. Interviews were conducted based on verbal consent. Multiple logistic regression analyses and several tests were performed to identify the factors associated with KAP related to COVID-19.

Results

A total of 492 of 576 Bangladeshi adults aged 18 years and above completed the interview, with a response rate of 85.4% (492/576). Of the 492 participants, 321 (65.2%) were male, and 304 (61.8%) lived in a rural area. Mean scores for knowledge, attitudes, and practices were 10.56 (SD 2.86), 1.24 (SD 0.83), and 3.17 (SD 1.5), respectively. Among the 492 respondents, 273 (55.5%) had poor knowledge, and 251 (49%) expressed a negative attitude; 192 out of 359 respondents (53.5%) had poor practices toward COVID-19. Mean scores of knowledge, attitudes, and practices differed significantly across various demographic and socioeconomic groups. Rural residents had lower mean scores of knowledge (mean 9.8, SD 3.1, P<.001) and adherence to appropriate practice measures (mean 4, SD 1.4, P<.001) compared to their urban counterparts. Positive and statistically strong correlations between knowledge and attitudes (r=0.21, P<.001), knowledge and practices (r=0.45, P<.001), and attitudes and practices (r=0.27, P<.001) were observed. Television (53.7%) was identified as the major source of knowledge regarding COVID-19. Almost three-quarters of the respondents (359/492, 73%) went outside the home during the lockdown period. Furthermore, the study found that good knowledge (odds ratio [OR] 3.13, 95% CI 2.03-4.83, and adjusted OR 2.33, 95% CI 1.16-4.68) and a positive attitude (OR 2.43, 95% CI 1.59-3.72, and adjusted OR 3.87, 95% CI 1.95-7.68) are significantly associated with better practice of COVID-19 health measures.

Conclusions

Evidence-informed and context-specific risk communication and community engagement, and a social and behavior change communication strategy against COVID-19 should be developed in Bangladesh based on the findings of this study, targeting different socioeconomic groups.

Published: September 2021

Background

The COVID-19 pandemic has placed a huge strain on the health care system globally. The metropolitan area of Milan, Italy, was one of the regions most impacted by the COVID-19 pandemic worldwide. Risk prediction models developed by combining administrative databases and basic clinical data are needed to stratify individual patient risk for public health purposes.

Objective

This study aims to develop a stratification tool aimed at improving COVID-19 patient management and health care organization.

Methods

A predictive algorithm was developed and applied to 36,834 patients with COVID-19 in Italy between March 8 and the October 9, 2020, in order to foresee their risk of hospitalization. Exposures considered were age, sex, comorbidities, and symptoms associated with COVID-19 (eg, vomiting, cough, fever, diarrhea, myalgia, asthenia, headache, anosmia, ageusia, and dyspnea). The outcome was hospitalizations and emergency department admissions for COVID-19. Discrimination and calibration of the model were also assessed.

Results

The predictive model showed a good fit for predicting COVID-19 hospitalization (C-index 0.79) and a good overall prediction accuracy (Brier score 0.14). The model was well calibrated (intercept –0.0028, slope 0.9970). Based on these results, 118,804 patients diagnosed with COVID-19 from October 25 to December 11, 2020, were stratified into low, medium, and high risk for COVID-19 severity. Among the overall study population, 67,030 (56.42%) were classified as low-risk patients; 43,886 (36.94%), as medium-risk patients; and 7888 (6.64%), as high-risk patients. In all, 89.37% (106,179/118,804) of the overall study population was being assisted at home, 9% (10,695/118,804) was hospitalized, and 1.62% (1930/118,804) died. Among those assisted at home, most people (63,983/106,179, 60.26%) were classified as low risk, whereas only 3.63% (3858/106,179) were classified at high risk. According to ordinal logistic regression, the odds ratio (OR) of being hospitalized or dead was 5.0 (95% CI 4.6-5.4) among high-risk patients and 2.7 (95% CI 2.6-2.9) among medium-risk patients, as compared to low-risk patients.

Conclusions

A simple monitoring system, based on primary care data sets linked to COVID-19 testing results, hospital admissions data, and death records may assist in the proper planning and allocation of patients and resources during the ongoing COVID-19 pandemic.
Pediatric Weight Management Through mHealth Compared to Face-to-Face Care: Cost Analysis of a Randomized Control Trial
Authors: Tully Louise , Sorensen Jan , O'Malley Grace
Published: September 2021

Background

Mobile health (mHealth) may improve pediatric weight management capacity and the geographical reach of services, and overcome barriers to attending physical appointments using ubiquitous devices such as smartphones and tablets. This field remains an emerging research area with some evidence of its effectiveness; however, there is a scarcity of literature describing economic evaluations of mHealth interventions.

Objective

We aimed to assess the economic viability of using an mHealth approach as an alternative to standard multidisciplinary care by evaluating the direct costs incurred within treatment arms during a noninferiority randomized controlled trial (RCT).

Methods

A digitally delivered (via a smartphone app) maintenance phase of a pediatric weight management program was developed iteratively with patients and families using evidence-based approaches. We undertook a microcosting exercise and budget impact analysis to assess the costs of delivery from the perspective of the publicly funded health care system. Resource use was analyzed alongside the RCT, and we estimated the costs associated with the staff time and resources for service delivery per participant.

Results

In total, 109 adolescents participated in the trial, and 84 participants completed the trial (25 withdrew from the trial). We estimated the mean direct cost per adolescent attending usual care at €142 (SD 23.7), whereas the cost per adolescent in the mHealth group was €722 (SD 221.1), with variations depending on the number of weeks of treatment completion. The conversion rate for the reference year 2013 was $1=€0.7525. The costs incurred for those who withdrew from the study ranged from €35 to €681, depending on the point of dropout and study arm. The main driver of the costs in the mHealth arm was the need for health professional monitoring and support for patients on a weekly basis. The budget impact for offering the mHealth intervention to all newly referred patients in a 1-year period was estimated at €59,046 using the assessed approach.

Conclusions

This mHealth approach was substantially more expensive than usual care, although modifications to the intervention may offer opportunities to reduce the mHealth costs. The need for monitoring and support from health care professionals (HCPs) was not eliminated using this delivery model. Further research is needed to explore the cost-effectiveness and economic impact on families and from a wider societal perspective.

Semisupervised Deep Learning Techniques for Predicting Acute Respiratory Distress Syndrome From Time-Series Clinical Data: Model Development and Validation Study (Preprint)
Authors: Lam Carson , Tso Chak Foon , Green-Saxena Abigail , Pellegrini Emily , Iqbal Zohora , Evans Daniel , Hoffman Jana , Calvert Jacob , Mao Qingqing , Das Ritankar
Published: September 2021

BACKGROUND

A high number of patients who are hospitalized with COVID-19 develop acute respiratory distress syndrome (ARDS).

OBJECTIVE

In response to the need for clinical decision support tools to help manage the next pandemic during the early stages (ie, when limited labeled data are present), we developed machine learning algorithms that use semisupervised learning (SSL) techniques to predict ARDS development in general and COVID-19 populations based on limited labeled data.

METHODS

SSL techniques were applied to 29,127 encounters with patients who were admitted to 7 US hospitals from May 1, 2019, to May 1, 2021. A recurrent neural network that used a time series of electronic health record data was applied to data that were collected when a patient’s peripheral oxygen saturation level fell below the normal range (<97%) to predict the subsequent development of ARDS during the remaining duration of patients’ hospital stay. Model performance was assessed with the area under the receiver operating characteristic curve and area under the precision recall curve of an external hold-out test set.

RESULTS

For the whole data set, the median time between the first peripheral oxygen saturation measurement of <97% and subsequent respiratory failure was 21 hours. The area under the receiver operating characteristic curve for predicting subsequent ARDS development was 0.73 when the model was trained on a labeled data set of 6930 patients, 0.78 when the model was trained on the labeled data set that had been augmented with the unlabeled data set of 16,173 patients by using SSL techniques, and 0.84 when the model was trained on the entire training set of 23,103 labeled patients.

CONCLUSIONS

In the context of using time-series inpatient data and a careful model training design, unlabeled data can be used to improve the performance of machine learning models when labeled data for predicting ARDS development are scarce or expensive.
The Application and Comparison of Machine Learning Models for the Prediction of Breast Cancer Prognosis: Retrospective Cohort Study (Preprint)
Authors: Xiao Jialong , Mo Miao , Wang Zezhou , Zhou Changming , Shen Jie , Yuan Jing , He Yulian , Zheng Ying
Published: September 2021

BACKGROUND

Over the recent years, machine learning methods have been increasingly explored in cancer prognosis because of the appearance of improved machine learning algorithms. These algorithms can use censored data for modeling, such as support vector machines for survival analysis and random survival forest (RSF). However, it is still debated whether traditional (Cox proportional hazard regression) or machine learning-based prognostic models have better predictive performance.

OBJECTIVE

This study aimed to compare the performance of breast cancer prognostic prediction models based on machine learning and Cox regression.

METHODS

This retrospective cohort study included all patients diagnosed with breast cancer and subsequently hospitalized in Fudan University Shanghai Cancer Center between January 1, 2008, and December 31, 2016. After all exclusions, a total of 22,176 cases with 21 features were eligible for model development. The data set was randomly split into a training set (15,523 cases, 70%) and a test set (6653 cases, 30%) for developing 4 models and predicting the overall survival of patients diagnosed with breast cancer. The discriminative ability of models was evaluated by the concordance index (C-index), the time-dependent area under the curve, and D-index; the calibration ability of models was evaluated by the Brier score.

RESULTS

The RSF model revealed the best discriminative performance among the 4 models with 3-year, 5-year, and 10-year time-dependent area under the curve of 0.857, 0.838, and 0.781, a D-index of 7.643 (95% CI 6.542, 8.930) and a C-index of 0.827 (95% CI 0.809, 0.845). The statistical difference of the C-index was tested, and the RSF model significantly outperformed the Cox-EN (elastic net) model (C-index 0.816, 95% CI 0.796, 0.836; P=.01), the Cox model (C-index 0.814, 95% CI 0.794, 0.835; P=.003), and the support vector machine model (C-index 0.812, 95% CI 0.793, 0.832; P<.001). The 4 models’ 3-year, 5-year, and 10-year Brier scores were very close, ranging from 0.027 to 0.094 and less than 0.1, which meant all models had good calibration. In the context of feature importance, elastic net and RSF both indicated that TNM staging, neoadjuvant therapy, number of lymph node metastases, age, and tumor diameter were the top 5 important features for predicting the prognosis of breast cancer. A final online tool was developed to predict the overall survival of patients with breast cancer.

CONCLUSIONS

The RSF model slightly outperformed the other models on discriminative ability, revealing the potential of the RSF method as an effective approach to building prognostic prediction models in the context of survival analysis.
Harnessing Distrust and the Power of Intercession for the Separation of Powers
Authors: Allard-Tremblay Yann
Published: September 2021

In what follows, I reflect on themes arising from my reading of Jacob Levy’s The Separation of Powers and the Challenge to Constitutional Democracy. According to Levy, the separation of powers in contemporary constitutional democracies is failing, thus endangering the rule of law. Briefly, this is because political parties have bridged the gap between the legislature and the executive: by giving rise to partisan politics that cross the institutional divide, political parties have dampened, if not disabled, the institutional incentive and motivation of the legislature to keep the executive in check. Furthermore, when this is combined with the myth of the united and undifferentiated people, which the executive, populistically, can easily claim to embody, the simple act of opposing the executive may be framed as seditious. In the end, the power of the executive is set free by the partisan loyalty of fellow party members and by the framing of opposition as disloyal and deleterious to the polity.

Freedom in Terms of the Win-Win-Win Papakonstantinidis: Bibliography
Authors: LA Papakonstantinidis
Published: September 2021

Concepts such as freedom cannot be measured and give material measurable results. Freedom is not measured. It leaves its philosophical imprint on independent thought. According to Jean-Jacques Rousseau (Note 1), it recedes only to leave room for political freedom The supposed absolute freedom based on the quantity of material goods and choices actually leads to the commitment of individualism. Because it is difficult to change this relationship between materialism and individualism, we focus on philosophical freedom through self-knowledge that will answer the triple question (1) what is best for me, (2) what is best for you, (3) what is best for community in which we negotiate a win-win-win reasoning for everyone who negotiates with another in the community Thus arises a win-win-win inner freedom with an immeasurable result, which at its limit is identified with the complete independence of the soul and the spirit.

Influence of Marble Dust Filler on Marshal Properties of Hot Mix Asphalt
Authors: Raza Mohsin
Published: September 2021

Abstract: Literature review reveals that mineral fillers play a vital role in altering the properties of asphalt concrete. Despite filler being a small part of asphalt, has a predominant effect on the performance characteristics of asphalt concrete. Millions tons of marble waste is being generated by marble processing industries, leading to environmental pollution and loss of valuable land. Developed countries have strict policies for waste disposal whereas in developing countries there are almost no policies. Hence, in this research, an effort has been made to evaluate the influence of marble dust on the strength properties and permanent deformation resistance of asphalt concrete. For this purpose optimum binder content has been determined by using 5.5% conventional limestone dust filler and after determination of optimum binder content, stone dust has been replaced with marble dust in increments of twenty five percent (i.e 0%, 25%, 50%, 75%, 100% ). The results of the tests performed on marble dust modified asphalt revealed that marble dust modified asphalt containing 50% marble dust have shown improvement in Marshal Stability and Flow values. Incorporation of marble dust up to 25% and 50% has resulted in better volumetric properties in comparison with stone dust made mixes. Keeping in view the improvement in properties of asphalt concrete in connection with marble dust, the utilization of freely available marble dust in asphalt concrete will have a marked impact in reducing the cost of asphalt concrete as well as minimizing the environmental problems due to disposal of waste marble dust. Keywords: Asphalt Concrete, Marble Dust, Limestone dust, Marshal Stability and Flow

Abstract: Traffic signal control frameworks are generally used to monitor and control the progression of cars through the intersection of roads. Moreover, a portable controller device is designed to solve the issue of emergency vehicles stuck in overcrowded roads. The main objective of this paper is to design and implement a suitable algorithm and its simulation for an intelligent traffic signal simulator. The framework created can detect the presence or nonappearance of vehicles within a specific reach by setting appropriate duration for traffic signals to react accordingly. By employing mathematical functions and algorithms to ascertain the suitable timing for the green signal to illuminate, the framework can assist with tackling the issue of traffic congestion. The explanation relies on recent fixed programming time. Keywords: Smart Traffic Light System, Smart City, Traffic Monitoring.

For the result, When the upper light intensity (LDR 1 and LDR 2) is greater than the bottom (LDR 3 and LDR 4), solar cell will move upwards, and vice versa. When the light intensity of the left (LDR 1 and LDR 3) is greater than the right (LDR 2 and LDR 4), solar cell will move to the left, and vice versa. From the research, it could concluded that Solar Tracker can be applied to Wind-Solar technology solar cells

The debate about the qadim of nature is one of the theological issues that has never been found in agreement among  Muslim Scholars. This understanding is based on the way of their thinking and the scientific frame developed among Muslim scholars. If the concept of qadim is related to the context of time, qadim means a reality that is considered to have existed before time. Based on that argument, the question arised  is whether that the time existed before nature or did that time occur due to the movement of the nature? This study uses a qualitative approach, while data obtained from the study of literature and some related documents. The data verification process is carried out by comparing the study of Kalam and Falaq. In the perspective of Kalam, qadim is understood by the scholars rationally (philosophy) while the scholar of Kalam acknowledged it scientifically. This research concludes that Kalam scholars consider time exists due to the movement of the universe, so that nature is considered to have existed before time. Therefore, Kalam scholar  regards the nature is qadim.

The ovaries represent the female reproductive organs that determine the women's fertility status and their systemic and oral health, correlating to sex steroid hormone alteration. This study aimed to investigate the effect of cassava leaves extract treatment to SOD expression in the animal model-ovaries after Porphyromonas gingivalis injection. 15 female Sprague Dawley rats were used and divided into five groups: (1) control without cassava leaves extract treatment (C); (2) P. gingivalis without cassava leaves extract treatment (T1); (3) P. gingivalis and cassava leaves extract (T2); (4) P. gingivalis and vitamin C (T3); and (5) P. gingivalis and metronidazole (T4). Animal were euthanised at day seven after the initial treatment to collect ovaries. The ovaries sections were immunohistochemically stained to quantify SOD expression using light microscope while the Image J software was used to quantify the SOD expression. The results showed that all of the follicle types had the same intensity of SOD expression. Most of the follicles exhibited low intensity of SOD expression, except for atretic follicles. In conclusion, P. gingivalis and cassava leaves extract influenced SOD expression in the ovaries of animal models, which increased the SOD expression.
¿Un bicentenario ambientalmente sostenible?
Authors: Roldán-Chacón Carmen Alexa , Peña-Vargas Vilma
Published: September 2021

El artículo explora el tema ambiental desde un enfoque de la sostenibilidad a propósito del bicentenario de Costa Rica. Desde una visión crítica y más allá de una enunciación de los problemas ambientales que padece la sociedad, se hace un llamado urgente a cambiar la actitud personal, institucional y nacional para comprender que la humanidad está dentro de una red vital interconectada que la sitúa como la especie responsable de la catástrofe pero también la especie decisiva para la transformación.

La investigación recorre más de 200 años de la historia ambiental y rescata algunos elementos, para concluir que así como ha habido aciertos, se han tomado decisiones que atentan contra la seguridad en materia ambiental. La idea no es continuar con los lamentos o búsqueda de culpables, se trata de asumir responsabilidades y volver al camino de la Costa Rica sostenible que está en nuestro imaginario y, por lo tanto, que sí es posible.
Los objetivos onusianos y el papel predominante que ha desempeñado la Unión Europea para el desarrollo
Authors: Nobels Aliénaure
Published: September 2021

This review article discusses the unprecedented commitments adopted by the international community that have paved the way for the Millennium Development Goals and the Sustainable Development Goals, as well as the leading role that the European Union has played in regard to development aid. Its ambition consists in exploring why the implementation of such goals on a global scale has not yet aligned with the rhetoric of these commitments and with the transformative opportunities they offer. This paper first analyses the mixed results of the Millennium Development Goals, as well as the Sustainable Development Goals, which reflect a paradigm shift emanating from all world leaders to address current global challenges. It then expounds how the European Union, guided by its universal values and principles it aspires to promote in the rest of the world, and considering trade as a powerful lever for development, has helped developing countries to integrate into the global trading system. The latter also embodies a political model by integrating environmental concerns and sustainable development into its own treaties and plays a predominant role in the elaboration and implementation of these global goals. Finally, this article attempts to explain why the globalisation of the economy engenders deep inequalities, destroys the environment, and thus hinders the implementation of such goals by subordinating the social and environmental dimensions of sustainable development.
Socialización de la Agenda 2030

Published: September 2021

The proposal in this article is about cases and examples of practices linked to 2030 Agenda,  and it aims to answer the question of whether it could be considered that 2030 Agenda hase been socialized in such a way beyond national state actors. To this end, the previous efforts of the United Nations will be analyzed, the four Decades for Development and Millennium Development Goals to conclude that while the Latter succeeded in positioning the issue of development on the global agenda, they did not adequately permeated in actors other than the state actors and international organizations involved and in this case, undoubtedly, 2030 Agenda has played a better role. 

In this regard, the article analyses the specific case of Recommendation 26/2019 issued by the State Commission on Human Rights of the State of Jalisco (Mexico), in September of 2019, on the issue of the healthy environment of the inhabitants of the municipality of San Pedro Tlaquepaque. This recommendation stands out due to consider much of its content in the 2030 Agenda and applicable Sustainable Development Goals and for mandating to the municipal government to train all city council staff on the 2030 Agenda for Sustainable Development, both issues, coadjuvant in the referred socialization

A new approach to the application of the principles of sustainable development
Authors:   Latvia University of Life Sciences and Technologies, Trusina Inese , Jermolajeva Elita ,   Latvia University of Life Sciences and Technologies
Published: September 2021

Most of the environmental, economic, social and political problems that have given rise to the global crisis continue to grow negatively and rapidly. It is with this situation that the world community has faced, feeling the consequences of earlier decisions. It is natural to raise the question: why, despite enormous efforts, it is not possible to reverse the negative trends and ensure the transition to sustainable development of the world community. In order for the criteria of sustainable development to meet these requirements, it is necessary to determine the main governing laws and find a way to measure different quality social, natural processes and resource flows in stable and universal units of measurement (measures). The article presents the basic definitions for the development of a formalized description of the tasks of monitoring sustainable development that meets the principles and requirements of sustainable development. It provides examples of calculating the parameters of sustainable development of Latvia and their primary interpretation. To formalize the tasks of sustainable development, the authors considered the methodology of systems analysis, methods of managing sustainable development projects using the concept of flows of full and useful power in open non-equilibrium stable systems, flows model of interactions in the system ‘man - society – nature’, as well as the theory of a unified system of space-time measurements. The main conclusions are: the system of four universal indicators of sustainable development shows that by 2019 the system of Latvia had a trend towards non-sustainable development. A decrease in consumption indicates an extensive development and is the result of a decrease in population, and is not associated with improving the structure of resource consumption and their efficient use.
