Published: April 2021

The sensitivity of the human eye varies with the different lighting conditions to which it is exposed. The cone photoreceptors perceive the color and work for illuminance conditions greater than 3.00 cd/m² (photopic vision). Below 0.01 cd/m², the rods are the cells that assume this function (scotopic vision). Both types of photoreceptors work coordinately in the interval between these values (mesopic vision). Each mechanism generates a different spectral sensibility. In this work, the emission spectra of common sources in present public lighting installations are analyzed and their normative photopic values translated to the corresponding mesopic condition, which more faithfully represents the vision mechanism of our eyes in these conditions. Based on a common street urban configuration (ME6), we generated a large set of simulations to determine the ideal light point setup configuration (luminance and light point height vs. poles distance ratio) for each case of spectrum source. Finally, we analyze the derived energy variation from each design possibility. The results obtained may contribute to improving the criterion of light source selection and adapting the required regulatory values to the human eye vision process under normalized artificial street lighting condition, reaching an average energy saving of 15% and a reduction of 8% in terms of points of light required. They also offer a statistical range of energy requirements for lighting installation that can be used to generate accurate electrical designs or estimations without the necessity of defining the exact lighting configuration, which is 77.5% lower than conventional design criteria.
Constructing Organic Food through Urban Agriculture, Community Gardens in Seville
Authors: Jordi-Sánchez Mario , Díaz-Aguilar Antonio Luis
Published: April 2021

The growing presence of community or allotment gardens seeks to respond to the challenges of today’s urban societies in terms of sustainability. The food dimension of this phenomenon is one of its most important aspects, with clear repercussions on improving the quality of life of the allotment gardeners and their families. Through observation and qualitative analysis of some community urban gardens in southern Spain (Andalusia), this paper notes that the people who cultivate allotments within these community gardens attribute a wide variety of different meanings to their practices. One essential contribution of this research is the finding that this plurality of meanings moves beyond the rational-technical dimension of the act of growing, while at the same time redefining the act of consuming organic food, because of its connection with productive and social activities.

The water management of cities and villages faces many challenges. Aging infrastructure systems operate for many years after their theoretical lifetime (operation) with a very high need for reconstruction and repair. The solution is proper rainwater management. The investigated area is part of the cadastral area of the Nitra city. This article is based on the use of geographic information systems (GIS) as tools in proposing water retention measures that are needed to improve the microenvironment of the city. We proceeded in several steps, which consisted of area analysis, survey, surface runoff calculations in urbanized areas, proposal of a suitable solution for given location. For real possibilities of rainwater management procedures, a new site on the outskirts of the city was selected. In the given locality, it was possible to use water infiltration as a solution. The locality has suitable conditions of land ownership, pedological conditions, the slope of the area and also the interest of the inhabitants in the ecological solution. The outlined study indicates the need to continue research on the reliability of rainwater management practices.

Published: April 2021

Actual flood mapping and quantification in an area provide valuable information for the stakeholder to prevent future losses. This study presents the actual flash flood quantification in Al-Lith Watershed, Saudi Arabia. The study is divided into two steps: first is actual flood mapping using remote sensing data, and the second is the flood volume calculation. Two Sentinel-1 images are processed to map the actual flood, i.e., image from 25 May 2018 (dry condition), and 24 November 2018 (peak flood condition). SNAP software is used for the flood mapping step. During SNAP processing, selecting the backscatter data representing the actual flood in an arid region is challenging. The dB range value from 7.23–14.22 is believed to represent the flood. In GIS software, the flood map result is converted into polygon to define the flood boundary. The flood boundary that is overlaid with Digital Elevation Map (DEM) is filled with the same elevation value. The Focal Statistics neighborhood method with three iterations is used to generate the flood surface elevation inside the flood boundary. The raster contains depth information is derived by subtraction of the flood surface elevation with DEM. Several steps are carried out to minimize the overcalculation outside the flood boundary. The flood volume can be derived by the multiplication of flood depth points with each cell size area. The flash flood volume in Al-Lith Watershed on 24 November 2018 is 155,507,439 m3. Validity checks are performed by comparing it with other studies, and the result shows that the number is reliable.
Econometrics of Anthropogenic Emissions, Green Energy-Based Innovations, and Energy Intensity across OECD Countries

Published: April 2021

The increasing global attention on climate change underscores the importance of alternative energy technologies with emission reduction effects. However, there are several caveats of economic productivity and environmental sustainability tradeoffs that require empirical consideration—owing to long-term effects on climate change. Here, we examine the relationship between emissions, green energy-based innovations, and energy research and development across energy-intensive OECD countries while accounting for industrial structure dynamics. We utilize several novel time series and panel estimation techniques including time-varying causality, defactored instrumental variable-based homogeneous, and heterogeneous slope dynamics that control for unobserved common factors. Our empirical assessment emphasizes the significance of energy research and development in expanding green energy innovations while reducing long-term emissions. Conversely, continual dependence on obsolete energy research and development may worsen environmental sustainability. However, the inclusion of green energy technologies offset environmental pollution without compromising economic productivity. Besides, the mitigation effect of energy research and development is channeled through a decline in energy intensity and technological advancement. We show that green energy-based innovations and energy research and development play a critical role in achieving environmental sustainability in OECD countries.

nLossFinder—A Graphical User Interface Program for the Nontargeted Detection of DNA Adducts
Authors: Sousa Pedro , Martella Giulia , Åberg K. , Esfahani Bahare , Motwani Hitesh
Published: April 2021

DNA adductomics is a relatively new omics approach aiming to measure known and unknown DNA modifications, called DNA adducts. Liquid chromatography–tandem mass spectrometry (LC-MS/MS) has become the most common method for analyzing DNA adducts. Recent advances in the field of mass spectrometry have allowed the possibility to perform a comprehensive analysis of adducts, for instance, by using a nontargeted data-independent acquisition method, with multiple precursor m/z windows as an inclusion list. However, the generated data are large and complex, and there is a need to develop algorithms to simplify and automate the time-consuming manual analysis that has hitherto been used. Here, a graphical user interface (GUI) program was developed, with the purpose of tracking a characteristic neutral loss reaction from tandem mass spectrometry of the nucleoside adducts. This program, called nLossFinder, was developed in the MATLAB platform, available as open-source code. Calf thymus DNA was used as a model for method optimization, and the overall adductomics approach was applied to DNA from amphipods (Monoporeia affinis) collected within the Swedish National Marine Monitoring Program. In the amphipod DNA, over 150 putative adducts were found in comparison to 18 using a manual approach in a previous study. The developed program can improve the processing time for large MS data, as it processes each sample in a few seconds, and hence can be applicable for high-throughput screening of adducts.

Authors: Koshiaris Constantinos , Van den Bruel Ann , Nicholson Brian D , Lay-Flurrie Sarah , Hobbs FD Richard , Oke Jason L
Published: April 2021

Background

Patients with myeloma experience substantial delays in their diagnosis, which can adversely affect their prognosis.

Aim

To generate a clinical prediction rule to identify primary care patients who are at highest risk of myeloma.

Design and setting

Retrospective open cohort study using electronic health records data from the UK’s Clinical Practice Research Datalink (CPRD) between 1 January 2000 and 1 January 2014.

Method

Patients from the CPRD were included in the study if they were aged ≥40 years, had two full blood counts within a year, and had no previous diagnosis of myeloma. Cases of myeloma were identified in the following 2 years. Derivation and external validation datasets were created based on geographical region. Prediction equations were estimated using Cox proportional hazards models including patient characteristics, symptoms, and blood test results. Calibration, discrimination, and clinical utility were evaluated in the validation set.

Results

Of 1 281 926 eligible patients, 737 (0.06%) were diagnosed with myeloma within 2 years. Independent predictors of myeloma included: older age; male sex; back, chest and rib pain; nosebleeds; low haemoglobin, platelets, and white cell count; and raised mean corpuscular volume, calcium, and erythrocyte sedimentation rate. A model including symptoms and full blood count had an area under the curve of 0.84 (95% CI = 0.81 to 0.87) and sensitivity of 62% (95% CI = 55% to 68%) at the highest risk decile. The corresponding statistics for a second model, which also included calcium and inflammatory markers, were an area under the curve of 0.87 (95% CI = 0.84 to 0.90) and sensitivity of 72% (95% CI = 66% to 78%).

Conclusion

The implementation of these prediction rules would highlight the possibility of myeloma in patients where GPs do not suspect myeloma. Future research should focus on the prospective evaluation of further external validity and the impact on clinical practice.

Published: April 2021

Key Points

We investigated the performance and hemocompatibility of a new polysulfone hemodialyzer with enhanced membrane properties.

β2-Microglobulin removal rate was noninferior to both comparator dialyzers and superior to a cellulose-acetate–based dialyzer.

The dialyzer showed a favorable hemocompatibility profile on the basis of markers for complement, cell and contact activation, and coagulation.

Background

High-flux dialyzers effectively remove uremic toxins, are hemocompatible to minimize intradialytic humoral and cellular stimulation, and have long-term effects on patient outcomes. A new dialyzer with a modified membrane surface has been tested for performance and hemocompatibility.

Methods

This multicenter, prospective, randomized, crossover study involved the application of the new polysulfone-based FX CorAL 600 (Fresenius Medical Care, Bad Homburg, Germany), the polyarylethersulfone-based Polyflux 170H (Baxter Healthcare Corporation, Deerfield, IL), and the cellulose triacetate–based SureFlux 17UX (Nipro Medical Europe, Mechelen, Belgium), for 1 week each, to assess the noninferiority of the FX CorAL 600’s removal rate of β2-microglobulin. Performance was assessed by removal rate and clearance of small- and medium-sized molecules. Hemocompatibility was assessed through markers of complement, cell activation, contact activation, and coagulation.

Results

Of 70 patients, 58 composed the intention-to-treat population. The FX CorAL 600’s removal rate of β2-microglobulin was noninferior to both comparators (P<0.001 versus SureFlux 17UX; P=0.0006 versus Polyflux 170H), and superior to the SureFlux 17UX. The activation of C3a and C5a with FX CorAL 600 was significantly lower 15 minutes after treatment start than with SureFlux 17UX. The activation of sC5b-9 with FX CorAL 600 was significantly lower over the whole treatment than with SureFlux 17UX, and lower after 60 minutes than with the Polyflux 170H. The treatments with FX CorAL 600 were well tolerated.

Conclusions

FX CorAL 600 efficiently removed small- and medium-sized molecules, showed a favorable hemocompatibility profile, and was associated with a low frequency of adverse events in this study, with a limited patient number and follow-up time. Further studies, with longer observation times, are warranted to provide further evidence supporting the use of the new dialyzer in a wide range of therapeutic options, and for long-term treatment of patients on hemodialysis, to minimize the potential effects on inflammatory processes.
A Hybrid Power System for a Permanent Colony on Mars
Authors: Pombo Daniel Vázquez
Published: April 2021

Since the dawn of humanity, people have contemplated the sky exploring the firmament. However, it was not until the twentieth century that humans were able to leave Earth and visit other celestial objects. In fact, nowadays, rovers roam Mars on a daily basis pushing the limits of science in a seemingly routine fashion. It is just a matter of time before humanity sets foot on the red planet with the aim of establishing a permanent colony. Such a complex endeavour demands continuous research, simulation, and planning. Consequently, this paper is aimed at starting a proper discussion about the configuration and design of a suitable power system for said Martian outpost. An initial literature review leads to the definition of a reference colony and its growing stages, which is followed by a revision of available energy-related technologies leading to a concrete design of a suitable electrical network. Lastly, the proposed hybrid power system is evaluated in terms of its reliability during the long-term operation under the extreme environmental conditions of Mars. The reference colony starts as an unmanned mission, as robots will prepare the selected location for the first human inhabitants. Later, it suffers several upgrades in size reaching a permanent population of 100 people. Therefore, a holistic approach is needed when designing the power system in order to ensure the continuous supply of the colony. Finally, the selected topology of the colony’s power system is presented.

Published: April 2021

Patient’s safety in Mexico regarding the use of medications is a vital and very neglected topic since the community, and the hospital population is at serious risk of suffering from any medication-related problem. Nowadays, the health institutions and the Federal Government have been made isolated efforts to contextualize the issue of safety in the use of medications. Still, the risk for the population that consumes drugs is latent throughout the medication macroprocess, from selection to the monitoring of therapies prescribed to patients. Therefore, we present real examples of events that occurred lately in Mexico and other countries because they were classified and analyzed according to the medication macro-processes and because this group of authors suggests a possible solution to them, which could be adapted to the conditions of each particular situation.
Religious mysticism of the “American Dream” in the tale “The King's Indian” by John Champlin Gardner Jr.
Authors: Vikhrova Kseniya A.
Published: April 2021

The metanarrative of the “American Dream” has a comprehensive impact on the social, political and cultural life of the United States, it attracts unflagging attention of researchers and it is interpreted in a significant number of works of art. This article analyses the functioning of the religious and mystical experience as a factor in achieving the “American Dream” “American Dream” in the tale “The King's Indian” (1974) by John Champlin Gardner Jr. (1933-1982), and it also attempts to determine the mechanism for the embodiment of the national utopian project in this work of fiction. The analysis examines the constituent elements of the project in synchronic and diachronic projections, it highlights the levels of the project actualisation in the work, it analyses how the characters try to implement it in relation to their worldview and individual existential plans; thus, successful and unsuccessful models of the achieving the “American Dream” are found. As a result, it is proved that the failure is due to the lack of religious mysticism. The failure leads to the destruction of the character's existential plan, built in accordance with the utopian project, and to its possible subsequent reconstruction. The successful realisation of the “American Dream” is possible only when the character follows “self-reliance" and trusts the transcendental forces. “The King's Indian” also reflects the philosophical and aesthetic program of “moral literature”, later formulated by Gardner in the essay of the same name.
Psychoanalysts of the first quarter of the 20th century about “Crime and Punishment” by Fyodor Dostoevsky
Authors: Gornostaeva Svetlana A.
Published: April 2021

The article examines the judgements of representatives of psychoanalysis of the early 20th century on the life and work of Fyodor Dostoevsky and, in particular, his novel "Crime and Punishment". The works of such famous psychoanalysts and followers of psychoanalysis as Alfred Adler. Jolan Neufeld, Sigmund Freud and Erich Seligmann Fromm are analysed. In the article "Dostoevsky" Adler, noting the contradictory nature of the characters, points to the general direction of movement for them towards finding inner peace, which, in turn, reveals a similarity with the nature of the writer himself. The researcher's particular attention is drawn to the theme of the boundaries of what is permitted and what is not permitted in Dostoevsky's work. Neufeld in his work "Dostoevsky" indicates that the basis of artistic depiction in the work of Dostoevsky is the emotional experience of the writer himself, whose personality makeup the psychoanalyst assesses as hysterical, which, in turn, turns out to be characteristic of his heroes. The researcher also notes the writer's increased attention to the category of the unconscious and highlights a number of features characteristic of Dostoevsky's poetics. In the well-known work of Freud "Dostoevsky and Parricide", the influence of "unconscious impulses" in the work of the Russian classic on the structure and peculiarities of plot lines in his works is indicated. The founder of neopsychoanalysis, Fromm, also draws attention to the category of the unconscious, but he is more inclined to interpret the behaviour of the heroes taking into account social and worldview factors. On the whole, the considered studies of psychoanalysts laid the foundations for a close study of the features of psychologism in Dostoevsky's work.
On the question of the perception of the absurd in modern literary practice (on the example of the piece of Ivan Vyrypaev's «Dreams»)
Authors: Muraveva Alla V.
Published: April 2021

The article is devoted to the parallel consideration of two questions: the text, on the one hand, deals with a set of absurdist techniques and methods stated in the text of Ivan Vyrypaev “Dreams”, and with another – attempt projection composite-content structure plays in the history of the formation and development of the absurd in Russian literary practice of the 20th century. In the course of the study, it was found that the entire set of tools that absurdise the space of the play can be divided into three parts: 1) corresponding to the absurdist-avant-garde techniques of the early 20th century, 2) illustrating the existential dramatic locus, 3) demonstrating the functioning of the phenomenon of the absurd in Russian postmodern drama. Built on the principles of displacement and substitution, the play “Dreams” series illustrates the change of the principle of construction of the text: from semi-abstract components that target the metaphorisation of space in text and in direct violation of formal logic, the play by introducing social commentary comes to the staging of existential issues, and through it, mainly through the absurdist element that goes to a typical post-modern principles of organisation of the text. The main conclusion of this research is the thesis about the characterisation of “Dreams” as a metaphor play that reflects the dynamics of the development of the absurd in the 20th century.

Published: April 2021

The memoirs of Vasiliy Gloriantov, which saw the light at the early 20th century and devoted to the internal life of Nizhny Novgorod Chamber of State Property, are the only published memoirs written by a former employee of Nizhny Novgorod Chamber of State Property. Memoir literature is a source of an additional character, deepening the description of certain facts and events. The issue of the reliability of the events contained in these recollections has not been previously considered. In the course of studying memoirs and comparing them with published documents and previously unpublished archival materials, a number of persons were identified whose names were hidden by Vasiliy Gloriantov, and certain inaccuracies in the dating of events were revealed. Information on drunkenness and official misconduct by chamber employees, contained in memoirs, is confirmed in preserved archival materials. According to the results of the study, it was concluded that the memories of Vasiliy Gloriantov have significant value as a historical source, illuminating the daily life of Nizhny Novgorod Chamber of State Property from the point of view of one of its direct participants.

Integration in the education of Muslims has become an agenda among Islamic intellectuals and activists. Where secular humanism and atheistic modernism leave Muslims with a legacy of educational dichotomy. Many contemporary Islamic educational institutions have been established since then, each with some distinctive integration models. Many Muslims advance the true integration of the Qur'an worldview in the Science and Technology curriculum whose students are at a critical stage of cognitive development, affective, spiritual, social, and ethical. This research presents qualitative reports that analyze several samples of integration models in a number of Islamic schools in Indonesia. In an effort to understand the Science and Technology Perspective this article assesses the worldview that has brought science and technology to its current stage. This research proposes a model for Islamic school education in which science and technology undergo thoughtful but holistic reconstruction, reinterpretation, and diversion of frameworks, and are organically infused with the Qur'an, and enrich 'Islamic studies' with good grounding and Science.

Published: April 2021

We present a review of the state of the art of the techniques and algorithms most used in the selection and detection of characteristics of electroencephalographic signals of people when consciously performing activities. These features are numeric parameters that describe the behavior of the signal and are the basis of patterns. In addition, previous experiences in the acquisition of electroencephalographic signals using the Epoc brain-computer interface manufactured by Emotiv are presented. First, some techniques used to eliminate artifacts (disturbances) present in the signal generated by blinking, strong breathing or other movements that contaminate the signal are presented. Later, the algorithms most frequently used in the processing of electroencephalographic signals are shown for the extraction of characteristics that describe the behavior of these patterns and that can be used to detect and recognize patterns in other signals. Finally, we present the lessons that we have acquired as a work team in the recording of electroencephalographic signals in order to be helpful for beginners.

Authors: URIBE-HERNÁNDEZ Mayra , LARIOS-OSORIO Víctor , ESCUDERO-NAHÓN Alexandro
Published: April 2021

Designing a mobile learning environment for mathematics education requires an understanding of how technology relates to various epistemological and pedagogical systems. The purpose of this study was to systematically analyze scientific literature on mobile learning in mathematics teaching through the axes of conceptual mapping within the framework of qualitative research. The analysis categories were: notion, categorization, characterization, differentiation, methodology and exemplification. The contribution of this work refers to the definition of mobile learning in the teaching of mathematics considering its characteristics, such as context creation, social interaction, multimedia content and usability. It was identified that mobile learning increases the possibilities of electronic learning and enables ubiquitous learning when the student is immersed in the learning context. The studies analyzed do not report a precise methodology that allows evaluating the relevance of the design of a mobile learning environment. However, it was identified that the choice of the pedagogical principles and the definition of a thematic axis are fundamental. In addition to the demand for teachers' theoretical, pedagogical and digital skills. This work provides elements that could guide further research and applications.

The product that was selected represents 60% of the company's sales and has a high rejection percentage, which is equivalent to monthly losses of $ 12,500,000.00 dollars. With this study, we identified, in a timely manner, the factors that affect the performance of the processes and proposed solutions that can be implemented to increase productivity, quality and improve customer satisfaction.

This paper presents the study and analysis of the use of water generated by air conditioning units in a company that manufactures electronic products for the medical, industrial and automotive industry. The company knows its environmental responsibility and is aware that water is necessary for life, therefore, it must be used and taken care of, to avoid that this resource is not renewable. We propose to use the water generated by the condensation of air conditioners in the company's areas. The project, which will recover and reuse the 2,104,400 liters of water generated in said refrigeration equipment through the design and implementation of functional irrigation systems with a coverage of 820m2 of grass. The use of water for this irrigation system is based on other elements, in the maintenance of the air conditioners, which avoids the generation of surplus chemical contaminants in the condensed water that is discharged.

At present, the drought periods are longer due to global warming, which has generated scarcity and water rationing, these conditions become the main problem in remote villages to urban areas and with little infrastructure. Mexico, with 653 aquifers throughout its territory, 106 are overexploited due to agricultural, mining, industrial and urban activities, which projects to the country a possible depletion and contamination of its vital liquid. For this reason, in order to contribute to a solution to the problem of water scarcity, by applying a control system to the technology used by the Peltier cells, a moderate flow of water is generated, since it condenses the particles of water suspended in the air. In this way, an array of Peltier cells will be implemented to obtain as much water as possible under environmental factors, such as humidity and temperature. In addition, when dealing with areas where the climate is arid, it is intended to use alternative sources of energy, of autonomous photovoltaic type, to take advantage of solar radiation and feed the control system in a self-sustaining manner.

In this work a Schlieren system is proposed. It is used to visualizing a convection flow, caused by the cooling surface a Peltier cell. The experimental assembly elements are a white LED light source (450 nm – 650 nm) that consumes 300 nW of measured electrical power, a Z-type optical reflective relay, a knife, an image acquisition system based on an Edmund EO02018C camera with CMOS RGB sensor and optomechanical components. A program for the analysis of the reference and the convection flow video was designed. As a first step, numerical integration and the phase unwrapping were carrid out to obtain the temperature gradients of the phenomenon under study and its temporal evolution. Then, each detection layer was analyzed, processing the data that provide more information on this phenomenon. It is important to note that the red layer of the camera has a better contrast in the visualization of the phenomenon, however, it is more affected by undesirable light diffraction. Therefore, the green layer of the camera is optimal for analyzing the phenomenon, this study confirms that that the Schlieren technique is ideal for observing phenomena where the temperature gradient is small and there are convection flows.

The general objective of this research is to sense and monitor the main variables that affect biodigestion processes; temperature, hydrogen potential (pH), humidity, volume and pressure within the bioreactor, and correlate them with the production of biogas, through a real-time monitoring system. For the development of the system design, information was collected on the variables and factors that affect the biodigestion process. Subsequently, the instruments and integral elements of the monitoring and sensing system were selected, all these electronic devices for commercial use and mentioned below. An LM35 sensor for temperature measurement, an industrial analog type measuring electrode for pH measurement, an FC-28 for moisture measurement, an MQ2 electrochemical sensor for measurement of methane production, an HC-SR04 ultrasonic sensor for level measurement (related to the volume of the biodigester) and a piezoelectric sensor MPX2202DP case 344C-01 for pressure measurement. The values captured by the sensors will be displayed in real time in a Visual Studio application, and will be automatically saved in a database. The integration of the system was experimentally tested in a span of 12 days in the city of Hermosillo, Sonora, Mexico, where measurements were obtained for comparison with other authors.
