Authors: Shiriev R. R. , Borisov A. N. , Valeev A. A.
Published: June 2022

THE PURPOSE. Consider the problems of the heat transfer process in the structural elements of the LED light source. Describe the cooling system of an LED light source using an equivalent circuit and thermal resistances. Conduct a comparative analysis of cooling systems for LED lighting devices. Perform thermodynamic calculations of the light device radiator using computer programs of automatic design systems. Suggest a way to improve the heat transfer properties of the radiator of the LED light source.

METHODS. When solving the tasks set, the method of retrospective-prospective meta-analysis was used, computer programs of automatic design systems and direct determination of technical parameters using measuring instruments were used.

RESULTS. The article describes the relevance of the topic, discusses the features of the heat transfer process in the structural elements of the LED light source. Thermodynamic calculations of the radiator of the lighting device were made using computer programs of automatic design systems KOMPAS and SolidWorks. The article proposes a method for improving the heat transfer properties of the radiator of an LED light source.

CONCLUSION. There are many different cooling systems with their own advantages and disadvantages. The most efficient cooling systems are forced cooling systems, however, their use entails an increase in the final cost of the lighting device and a decrease in its light output due to an increase in energy consumption. Passive cooling systems are relatively cheap, but to provide effective cooling of LEDs, they must have a sufficient area of contact with the heat source, have good thermal conductivity and heat dissipation. In this case, the best way to improve the heat transfer properties of the radiator is to apply a special coating with a high heat transfer. This will increase the cooling efficiency with minimal cost without resorting to a significant change in the design features of an existing system.

Published: June 2022

THE PURPOSE. Detection of the dependences between the toxicity index of the components of crystalline solar panels EVA and Tedlar® and the factors of sample preparation of water extracts used in biotesting on the chemotactic reaction of Paramecium caudatum test objects using Biotester-2M as an analyzer. These factors included: the temperature of the extract, the exposure time of the extract of the studied objects in distilled water, and the use of otherkind of extract.

METHODS. In the course of the study, the biotesting method for the chemotactic reaction of Paramecium caudatum was used. In the experiments, an aqueous extract was prepared in accordance with PND F T 16.3.16-10. The resulting extracts were analyzed on a Biotester-2M device. For each experiment number, a study was carried out in three cuvettes, from each of which the device took 10 values. To assess the influence of extract temperature factors and exposure time, an experiment was carried out for temperatures of 4°C and 35°C, which allow taking into account the temperature at solid waste landfills at different times of the year. The extraction times were chosen to be 1, 7, 21, 28, 42 and 56 days. Data analysis was carried out using two-way replicated analysis of variance implemented using MatLab® tools. To assess the effect of the extraction medium, an experiment was carried out with the replacement of distilled water as an extract with mineral water of the Bonaqua brand and 1% acetone solution.

RESULTS. The error probability of the hypothesis about the influence of temperature and exposure time factors of the extract on the toxicity index was calculated at given significance levels. A comparative analysis of the average toxicity indices for the studied extraction media with distilled water, which is used as an extraction medium in approved biotesting methods, was carried out.

CONCLUSION. For complex organic compounds such as EVA and Tedlar® the toxicity indices will depend on a number of factors: the temperature of the extract, the residence time of the components in the extract, and the extraction medium.

Authors: Gvozdyakov D. V. , Zenkov A. V. , Lavrinenko S. V. , Matveeva A. A.
Published: June 2022

The relevance of the work is explained by the absence of the results of the heating effect of multicomponent coal-water slurries on rheological properties and characteristics of spraying in the literature.

PURPOSE. Efficiency substantiation of thermal preparation of coal-water slurries based on pyrogenetic liquid by the results of experimental studies.

METHODS. When solving this problem, the Brookfield RVDV-II+Pro rotary viscometer, general-purpose hydrometers, and the Interferometric Particle Imaging method were used.

RESULTS. It was found that when water in coal-water fuel is replaced by a similar amount of pyrogenetic liquid (no more than 25%), the density of the slurry increases by 14% at a temperature of 293 K. Preheating of coal-water slurries to 363 K reduces the increase in the density value to 7%. The experimental results showed that the greatest influence of the thermal preparation of the studied slurries on their dynamic viscosity is characteristic of the temperature range from 293 to 333 K. At such temperatures, a decrease in the viscosity of the fuel is possible by 17-20%. Preheating of slurries before spraying in the temperature range from 293 to 333 K makes it possible to increase jet spraying angle by 21-29% in comparison with two-component coal-water fuel at a temperature of 293 K. Substitution of more than 25% by weight of water with pyrogenetic liquid in coal-water fuel is impractical for the studied grade of coal from the point of view of a significant increase in viscosity. Preheating coal-water fuel before spraying reduces the average droplet size by 5-9%.

CONCLUSION. The efficiency of thermal preparation of coal-water slurries based on pyrogenetic liquid by the results of experimental studies of rheological properties and spraying characteristics was substantiated.

THE PURPOSE. Analysis of existing circuit and technical solutions for improving the quality of electricity in networks with traction load and assessment of their compliance with new properties of the electric network when switching to an active adaptive platform. Determination of the features of the operation of electric networks with traction load during the transition to an active-adaptive platform. Review of existing technical means and circuit solutions for improving the quality of electricity in electric networks with traction load and their analysis for compliance with new properties of the electric network.

METHODS. To solve the tasks set, a structural analysis of existing technical and circuit solutions was performed to improve the quality of electricity in electric networks with traction load.

RESULTS. In this article, the systematization of the compliance of technical means with the solved problems in the field of electricity quality is carried out. The features of the operation of electric networks with traction load during the transition to an active-adaptive platform are determined. Modern technical means and circuit solutions corresponding to the new properties of the electrical network are revealed. A variant of combining technologies for a complex effect on the quality of electricity is proposed.

CONCLUSION. When switching electric networks with traction load to an active adaptive platform in order to improve the quality of electricity, it is advisable to use technical means capable of providing PCE within acceptable limits in real time, depending on the operating modes of the power system and traction load. Such means include distributed generation, electric energy storage, active filter-compensating and balancing devices, FACTS technologies of the second generation. Classical approaches to solving problems with the quality of electrical energy based on the use of passive technical devices do not correspond to the new properties of active-adaptive networks with alternating current traction.
La autoría, autenticidad y originalidad reformuladas, y su aplicación en instalaciones contemporáneas múltiples y orgánicas
Authors: Coronado García Claudia María
Published: June 2022

Basado en la revisión de escritos de teóricos y conservadores, se propone reformular los conceptos de autoría, autenticidad y originalidad, promoviendo la ampliación de significados y alcances aplicables en instalaciones artísticas contemporáneas, incluso en aquellas realizadas con objetos orgánicos o materiales de fácil sustitución. En tales situaciones, ¿cómo debemos actuar como conservadores en casos en los que lo importante es la transmisión del significado, no así la materialidad del objeto? Para responder este cuestionamiento podríamos acudir a uno de los axiomas del arte conceptual, en donde la idea es arte, y la materialización, por tanto, es efímera, lo cual también pone en evidencia que la tarea del conservador contemporáneo no es como ni reside donde tradicionalmente se piensa. _____ Based on the review of writings by theorists and conservators, we propose a reformulation of the concepts of authorship, authenticity and originality, promoting the expansion of meanings and applicable scopes in contemporary art installations, even in those made with organic objects or easily replaceable materials. In such situations, how should we act as conservators in cases where the important thing is the transmission of meaning, not the materiality of the object?

Published: June 2022

The effective use of daylight is a critical design input that increases spatial qualities, sustainability, and energy efficiency targets in buildings. The emerging kinetic architecture concept supports these goals. It also recommends the use of building elements that are suitable for the design of dynamically environment-responsive façades. This study aims to explore the potential of kinetic envelopes for the design of optimal daylight efficient façades. The methodology is based on computational models of kinetic façade patterns applied to a generic building, which are further optimized to reveal the most efficient design. The façade features a modular pattern based on triangles, which, by simple rotation around the vertical axis, provides both daylight control and visual comfort. The results of a parametric analysis of the panel configurations based on daylight metrics, show that the proposed design helped achieving the most effective configuration for daylight savings.

Background: Uterine arteries embolization (UAE) is a minimally invasive procedure with good results when it is used as interventional treatment for patients diagnosed with benign or malignant uterine tumors. The main gynecological malignancies that are complicated by hemorrhages and would benefit from UAE are cervical cancer and endometrial cancer in late inoperable stages or following surgery. Methods: During five years, in the Bucharest University Emergency Hospital’s Obstetrics and Gynecology Department, from 605 patients to whom trans-catheter embolization of the uterine arteries was performed, 33 (5.45%) were diagnosed with cervical cancer (n = 31) and endometrial cancer (n = 2) in the advanced stage addressed for heavy acute vaginal bleeding and secondary anemia. Results: For those patients, UAE was used as palliative treatment. The average age of the patients in the evaluated group was 48.7 ± 8.3 years, and the average number of days of hospitalization was 4.72 ± 2.97 (range 1–11). The benefits of UAE include cessation of bleeding in up to 100% of cases and expanding the window of opportunity for secondary anemia correction. The most common side effects (pain, nausea) could be managed with mild analgesics and easily-accessible antiemetics. Conclusions: Considering these patients’ fragile advanced oncological status, surgical ligation should be adopted only in centers where UAE is not available. The article strengthens the need for interventional radiology departments in all regional emergency centers.

Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) combined with interval debulking surgery (IDS) constitutes an adjunctive treatment strategy in advanced ovarian cancer (AOC). This approach is based on the concept of perfusing chemotherapy targeting directly the site of residual tumor after optimal surgical debulking. It improves patients’ outcome in terms of overall survival (OS) and disease free survival (DFS). The correct selection of patients eligible for IDS + HIPEC is crucial: in particular, they must have shown a good response to neoadjuvant chemotherapy (NACT) and have a good performance status (PS). The application of HIPEC at the end of debulking does not seem to increase neither the rate of intra/postoperative complications nor the time of hospitalization. Clinical Cases: After approving an internal protocol for the application of HIPEC in our hospital, we have submitted four patients to IDS + HIPEC in the past 12 months. One of these patients underwent a minimally invasive procedure. No intra- or postoperative complications were observed. Results: All patients underwent IDS + HIPEC after being assessed as eligible and after showing a good response to NACT. In the course of IDS in all cases complete debulking was achieved. No patient developed intra- or postoperative complications. Conclusions: The addition of HIPEC to interval debulking surgery should be offered to all eligible patients, considering that the association of HIPEC to IDS seems to improve patients’ outcomes in terms of OS and DFS, without increasing post-operative morbidity .

Published: June 2022

Backgrounds: Cervical cancer was a primary epithelial malignant tumor in the cervix, which was one of the most common malignant tumor in gynecology. We aimed to investigate the relation of tumor microenvironment and the prognosis of cervical cancer patients. Methods: We conducted an extensive bioinformatics analysis aims to study the correlation between stromal/immune cells and the prognosis of cervical cancer. In order to investigate the associations between genes and overall survival (OS) of cervical cancer. We performed large-scale data analysis through a global gene expression profile. We analyzed the expression profile of cervical cancer using the Cancer Genome Atlas (TCGA) database. An immune score and stromal score depending on the estimation algorithm which can quantify the stromal or immune components of cervical cancer was obtained. Based on that, we divided the cervical cancer patients in the TCGA database into high- and low-score groups, and then the identified different expression genes (DEGs) that expression associated with cervical cancer patient’s prognosis was identified. After that, we generated protein-protein interaction (PPI) networks and interrelationship analyses of the immune system by performing functional enrichment analysis. Results: Our study showed that these 363 genes were primarily associated with immune/inflammatory responses. Meanwhile, Gene Expression Omnibus (GEO) confirmed that 9 genes (CX3CL1, SCML4, LYZ, FGD2, SLAMF6, GIMAP7, CCL19, SELP and POU2AF1) were significantly associated with cervical cancer prognosis. Conclusions: We have made a list of genes related to tumor microenvironment which would be potential biomarkers for the prognosis of cervical cancer patients.

Published: June 2022

Background: This study aimed to explore the association between BMI and/or central obesity parameters and measures of arterial hemodynamics to assess the effect of obesity on function of large arteries. Methods: Data was obtained from 634 subjects undergoing health assessment at Ruijin Hospital, Shanghai. Subjects were divided into 3 groups according to their Body Mass Index (BMI (kg/m2) <24 normal, 24–28 overweight, ≥28 obese). In addition, central obesity was described by waist-hip ratio (WHR) and waist-height ratio (WHtR). Radial arterial waveforms and carotid-femoral pulse wave velocity (cf-PWV) were measured with the subjects recumbent. Central arterial pressures were measured by pulse wave analysis of the radial waveform calibrated to peripheral cuff systolic (PSP) and diastolic pressure (PDP) to obtain central systolic pressure (CSP), central diastolic pressure (CDP), central pulse pressure (CPP), central augmentation pressure (CAP), and central augmentation index (cAIx). Pulse pressure was determined from the ratio of peripheral (PPP) and central (CPP) pulse pressure (PPP/CPP). Results: CAP and cAIx were lowest in the obese group (p < 0.01). Pressure amplification was significantly higher as BMI increased (p < 0.05). After adjusting for confounding factors, WC, WHtR and WHR were independent risk factors for cf-PWV (β = 0.120, p = 0.001, β = 0.103, p = 0.004, β = 0.092, p = 0.013), When BMI, WC, WHtR, WHR were put into the stepwise linear regression model, only WC was an independent risk factor for cf-PWV (β = 0.135, p < 0.001). Conclusions: Central obesity (WC and WHR) measures may have greater predictive value for vascular stiffness than BMI. This possibility warrants further studies focused on arterial wave travel and its relationship with body fat distribution.
The Galenic Heart in the Gothic Cathedral and the Adjournment in Discovery of Circulation
Authors: Kiraly Laszlo , Gulyas Balazs
Published: June 2022

Background: Aristotle’s tripartite concept of man—body, soul and spirit—formed the basis of the Galenic system that distinguished nurturing, vitalizing and animating tributary domains, governed by the liver, heart and brain, respectively. The Gothic cathedral structures into similar tripartite arrangements of nave, choir and sanctuary. We studied whether consistent parallels can be found between the Galenic concept of man, the Galenic heart itself and the structuring of the Gothic cathedral. Methods: Galenic literature along with scholastic texts were reviewed. Examples of Gothic cathedrals were visited and studied in locations. We used medieval analytical tools to compare characteristics of cathedral architecture and contemporary concepts on man and the heart. Results: Consistent parallels were found between the Galenic system and the structural parts of the Gothic cathedral. The principle of homology, intrinsic to both the Galenic system and Gothic architecture, identified the same tripartite organization in the Galenic heart itself and the segments could be projected onto the cathedral structure. Thus, the physical/nurturing domain was identified with the right ventricle inlet and the nave; the psychological/vitalizing domain corresponded with the right ventricle outlet/interventricular septum and the cathedral’s choir; the animating/spiritual domain paralleled with the left ventricle/aortic valve and the sanctuary in the cathedral. Conclusions: The Aristotelian/Galenic tripartite concept appears consistent with Gothic architecture and both provided a comprehensive view of the world; their relationship stems in a common philosophical and symbolic foundation. The tripartite interpretation was so coherent that it effectively delayed recognition of circulation and the heart’s role in it.

Towards a Smart Bionic Eye: AI-Powered Artificial Vision for the Treatment of Incurable Blindness
Authors: Beyeler Michael , Garcia Melani Sanchez
Published: June 2022

How can we return a functional form of sight to people who are living with incurable blindness? Despite recent advances in the development of visual neuroprostheses, the quality of current prosthetic vision is still rudimentary and does not differ much across different device technologies. Rather than aiming to represent the visual scene as naturally as possible, a Smart Bionic Eye could provide visual augmentations through the means of artificial intelligence–based scene understanding, tailored to specific real-world tasks that are known to affect the quality of life of people who are blind, such as face recognition, outdoor navigation, and selfcare. Here we propose to move away from thinking about prosthetic vision as the quest to restore natural vision and instead consider the possibility of providing visual augmentations designed to support a range of patient-relevant real-world tasks. The ability of a visual prosthesis to support everyday tasks might make the difference between abandoned technology and a widely adopted next-generation neuroprosthetic device.

Interferometry of Synthetic Aperture Radar (InSAR) can potentially contribute to the cost-effective regional or global monitoring of the degradation and restoration of peatlands. However, there are uncertainties about the links between InSAR results and peatland ecohydrological parameters, especially soil moisture. Here, we analyse the relationships between the temporal evolutions of InSAR coherence, ground displacements, and in-situ soil moisture measurements for a temperate raised bog at Ballynafagh, Co. Kildare, Ireland, in the period 2017-mid-2021. We also investigate the effects of a wildfire in June-July 2019 on those relationships. InSAR-derived ground displacements from Sentinel-1 C-band radar data indicate long-term subsidence of the intact and Active Raised Bog. Superimposed on the long-term displacement trends are annual oscillations that are linked to variations in rainfall and temperature and that are in phase with changes in soil moisture. We show that InSAR coherence is directly related to the change in soil moisture, with large changes causing coherence decrease or loss. The wildfire removed a 10-20 cm thick mossy vegetation layer across 60-70 % of the intact bog area. The SAR backscatter intensity in VV polarisation increased after the wildfire, but the InSAR coherence, the InSAR-derived surface displacements and the soil moisture were not noticeably affected. We therefore infer that C-band radar waves attenuate in the active vegetation layer, but penetrate through it into the upper few cm of the underlying peat. The SAR backscatter occurs primarily at this level in the peat, where its coherence is controlled by the soil moisture. These findings underpin application and interpretation of radar for monitoring of peatlands, even if affected by wildfires, which are forecast to increase in both frequency and intensity due to global warming.

A central question in modeling induced and natural earthquake nucleation is whether fault frictional properties measured in the laboratory are applicable to nature. A laboratory fault is generally just a few centimeters in length-width scale, while natural faults can be hundreds of meters to kilometers in extent. It is unknown whether laboratory fault friction data are applicable even to mesh dimensions (~1m) of earthquake simulators used in seismic hazard analysis. We report the first m-scale friction experiments on simulated fault wear material (gouge), performed at sliding rates relevant for earthquake nucleation. We show that fault friction and its dependence on slip rate, distance and gouge state are indistinguishable from those measured at cm-scale, despite heterogeneities in stress and slip velocity detected along the m-scale fault plane. We attribute this scale independence to slip being accommodated on microscale shear bands that evolve similarly at all scales, independently of heterogeneities in gouge density and boundary conditions. Our results imply that parameters derived from cm-scale friction experiments are directly applicable to modeling induced and natural earthquake nucleation on planar faults and provide key baseline data for future investigations into the effects of natural heterogeneities in gouge composition and fault topography on frictional scaling.
Potential for Perceived Failure of Stratospheric Aerosol Injection Deployment
Authors: Keys Patrick , Barnes Elizabeth , Diffenbaugh Noah , Hurrell James , Bell Curtis
Published: June 2022

As anthropogenic activities warm the Earth, the fundamental solution of reducing greenhouse gas emissions remains elusive. Given this mitigation gap, global warming may lead to intolerable climate changes as adaptive capacity is exceeded. Thus, there is emerging interest in solar radiation modification, which is the process of deliberately increasing Earth's albedo to cool the planet. Stratospheric aerosol injection (SAI) — the theoretical deployment of particles in the stratosphere to enhance reflection of incoming solar radiation — is one strategy to slow, pause or reverse global warming. If SAI is ever pursued it will likely be for a specific aim, such as affording time to implement mitigation strategies, lessening extremes, or reducing the odds of reaching a biogeophysical tipping point. Using an ensemble climate model experiment that simulates the deployment of SAI in the context of an intermediate greenhouse gas trajectory, we quantify the probability that internal climate variability masks the effectiveness of SAI deployment on regional temperatures. We find that, while global temperature is stabilized, substantial land areas continue to experience warming. For example, in the SAI scenario we explore, up to 55% of the global population experiences rising temperatures over the decade following SAI deployment, and large areas exhibit high probability of extremely hot years. These conditions could cause SAI to be perceived as a failure. Countries with the largest economies experience some of the largest probabilities of this perceived failure. The potential for perceived failure could therefore have major implications for policy decisions in the years immediately following SAI deployment.
Contemporary Remote Sensing Tools for Integrated Assessment and Conservation Planning of Ice-free Antarctica

Monitoring and understanding Antarctica is critical for conservation of its values. Remote sensing has been increasingly employed to observe large areas at higher frequency than traditional monitoring methods, enabling systematic assessments at low cost. However, currently there are limitations in the ability of the available remote sensing tools to answer the most pressing scientific, ecological, and biological questions associated with anthropogenic impacts, including climate change, in Antarctica. Here we summarise the latest findings on remote sensing tools and techniques, identifying the gaps and highlighting priority areas for future development. Major ongoing challenges concern the intensive cloud coverage and ephemeral snow cover that prevent ongoing observations of ice-free areas and the fine spatial scales required to undertake assessments of terrestrial ecosystems, their biota, and the human footprint. Opportunities arise in the realms of advanced statistical techniques to harness the potential of increasingly available data from orbital satellites and Unmanned Aerial Systems also commonly known as drones, at multiple scales and resolutions. We conclude that harnessing emerging technological advances in remote sensing will enable new understanding and ultimately protection of Antarctic ecosystems.

To view this open access article, please use the Published Article DOI.Speleothem δ18O is widely used as a proxy for rainfall amount in the tropics on glacial-interglacial to interannual scales. However, uncertainties in the interpretation of this renowned proxy pose a vexing problem in tropical paleoclimatology. Here, we present paired measurements of Mg/Ca and δ18O for multiple stalagmites from southwest Sulawesi, Indonesia, that that confirm changes in rainfall amount across ice age terminations. Collectively, the stalagmites span two glacial-interglacial transitions from 380 to 330 ky BP and 230 to 170 ky BP. Mg/Ca in our slow-growing stalagmites is affected by karst infiltration rates and prior calcite precipitation, making it a good proxy for changes in local rainfall. When paired, Mg/Ca and δ18O corroborate prominent shifts from drier glacials to wetter interglacials in the core of the Australasian monsoon domain. Deviations between the two proxies may reveal concurrent changes in rainfall amount and moisture-transport pathways indicative of regional monsoon circulation.
