Presentación del incidente de nulidad de actuaciones como cauce de admisión del recurso de amparo a la vista de la reciente sentencia del TEDH (15 de diciembre de 2022, asunto Olivares Zúñiga c. España)
Authors: Gómez de José Carolina
Published: July 2023

En esta breve contribución pretendo reflexionar sobre la excepcionalidad con que se configura el incidente de nulidad de actuaciones regulado en la Ley Orgánica del Poder Judicial, en la redacción dada por la Ley Orgánica 6/2007, de 24 de mayo, con carácter previo a la presentación del recurso de amparo, ante el Tribunal Constitucional, por vulneraciones de derechos fundamentales, imputables a los órganos jurisdiccionales. Pese a que se configura con carácter sumamente excepcional, en el sentido de que, «No se admitirán con carácter general incidentes de nulidad de actuaciones», veremos que en la práctica no es tal, y que para poder pasar uno de los filtros de admisibilidad del recurso de amparo ante el Tribunal Constitucional, en la mayoría de las ocasiones, deberemos presentar, «ad cautelam», el incidente de nulidad de actuaciones, si no queremos encontrarnos con una causa de inadmisión previa, a la controvertida justificación de la especial transcendencia constitucional. La reciente sentencia del TEDH, de 15 de diciembre de 2022, asunto Olivares Zúñiga c. España da un aliento de esperanza, en el sentido de que en los casos en que su uso no sea obligatorio, es decir, cuando la lesión de derechos fundamentales forme parte del conocimiento del proceso, no será necesaria su presentación. Lo que a buen seguro mejorará las estadísticas de inadmisiones de los recursos de amparo por esta causa.
Experimental validation of multiaxial fatigue theories to estimate fatigue life of helical compression spring
Authors: Nilesh.C. Ghuge  , Dattatraya Palande  , Rakesh Shriwastva
Published: July 2023

High-stress amplitudes and mean stress cycles are expected to be endured by helical compression springs utilized in a two-suspension wheeler's system. Fatigue failure of all these springs brings enormous eventual repair and replacement costs. A fatigue test is conducted to ascertain fatigue strength. The spring test plan is rather extensive due to the limited time and numerous test spring versions. Efforts were made to anticipate the helical spring's fatigue life. Multiaxial fatigue theories are examined in this work. The research paper aims to scrutinize the appropriate techniques that spring manufacturers should employ in the planning stage to calculate the fatigue life of helical compression springs. The criteria of Wang & Brown, Fatemi & Socie, Mitchell, Baumel & Seeger, and Smith & Watson are used in the present investigation. The results of the experiment and the predicted life are compared. Spring fatigue life is overvalued by the Wang-Brown criterion, while the Fatemi-Socie model offers a precise forecast of fatigue life.

Phage-based biocontrol is an alternative method for preventing and controlling the occurrence of Pseudomonas spp. in food products. However, the use of bacteriophages to control heat-stable protease Pseudomonas fluorescens is still rare. The objectives of this study were to isolate lytic bacteriophages of P. fluorescens, and to evaluate their efficacy in controlling P. fluorescens at the laboratory level. Among these strains, only one phage, ΦTIS1, was isolated by using P. fluorescens TISTR 1887 as the host. Further analysis using electron microscopy indicated that ΦTIS1 belongs to the Myoviridae family. This phage ΦTIS1 was relatively stable at pH and temperature ranges of 4.0 to 12.0 and 4, 30, 37, and 45°C, respectively, after 1.5 h incubation. The partial ΦTIS1 genome was a linear double-stranded with a total length of 87,646 bp and a G + C content of 54.71%. In vitro studies of the effect of bacteriophages against P. fluorescens TISTR 1887 with phage ΦTIS1 using various multiplicity of infection (MOI) values showed a significant decrease in bacterial numbers during 6-12 hours of incubation, followed by bacterial regrowth. However, the phage was still able to significantly reduce the bacterial numbers compared to the control without phage. These findings suggest that phage ΦTIS1 has the potential to be an effective method for controlling the prevalence of spoilage-causing P. fluorescens strains in dairy industries.

Aims: To study the impact of past COVID 19 infections on various hematological parameters and morbidity in patients with active dengue infection by assessing days of hospital stay, platelet transfusion etc.

Study Design: Prospective study.

Place and Duration of Study: Department of Pathology, Baba Raghav Das Medical college, Gorakhpur, India between June 2022 to November 2022.

Methodology: 189 patients with active dengue infection, proven on Dengue ELISA for IgM detection, were included in this prospective study. Hematological parameters along with demographic profiles and clinicopathological details were recorded for the patients at the time of admission.

Results: The mean age was comparable between the two groups, dengue patients with history of COVID 19 (Group A) being 26.93±14.27 years and dengue patients with no history of COVID 19 (Group B) being 28.52±17.65 years. Group A patients were found to have higher mean platelet count [68200.00±28153.33] than Group B patients [54181.21±31792.06]. The fatality rate was 2.68% in the Group A patients and 5% in the group B.

Conclusion: Our research indicates that individuals with a history of COVID-19 infection have reduced dengue mortality. However, we cannot presume a causal association between dengue and COVID-19 infection prognosis.

Aims

Heart failure (HF) guidelines recommend initiation and optimization of guideline‐directed medical therapy, including mineralocorticoid receptor antagonists (MRAs), before hospital discharge. However, scientific evidence for this recommendation is lacking. Our objective was to determine whether initiation of MRA prior to hospital discharge is associated with improved outcomes.

Methods and results

We performed a secondary analysis of 6197 patients enrolled in the RELAX‐AHF‐2 study. Patients were divided into four groups according to MRA therapy at baseline and discharge. At baseline 30% of patients received MRA therapy, which increased to 50% of patients at discharge. In‐hospital initiation of an MRA was observed in 1690 (27%) patients, 1438 (23%) patients remained on MRA therapy, 418 (7%) patients discontinued MRA treatment, and 2651 (43%) patients did not receive an MRA during hospital stay. Compared with patients who did not receive MRA therapy, in‐hospital initiation of an MRA was independently associated with lower risks of mortality (multivariable hazard ratio [HR] 0.76, 95% confidence interval [CI] 0.60–0.96; p = 0.02), cardiovascular death (HR 0.77, 95% CI 0.59–1.01; p = 0.06), hospitalization for HF or renal failure (HR 0.72, 95% CI 0.60–0.86; p = 0.0003) and the composite endpoint of cardiovascular death and/or rehospitalization for HF or renal failure (HR 0.71, 95% CI 0.61–0.83; p < 0.0001) at 180 days. These results were independent of baseline left ventricular ejection fraction.

Conclusion

In patients hospitalized for acute HF, in‐hospital initiation of an MRA was associated with improved post‐discharge outcomes, independent of left ventricular ejection fraction and other potential confounders.

Published: July 2023

Background Patient-reported outcome measures (PROMs) are standardized, validated tools that translate subjective patient-reported concerns about their health status into quantitative data. PROMs were initially developed as research instruments; however, they have more recently been recognized as important clinical tools. PROMs have not been widely adopted into surgical practices and this study sought to uncover the system requirements of a platform to integrate PROMs into surgical practice, as perceived by surgeons.

Methods Semi-structured interviews were performed from November 2019 until August of 2020. Interviews continued until thematic saturation was achieved. All interviews were recorded and transcribed verbatim. Qualitative interview data were thematically analyzed using an inductive approach.

Results Analysis revealed 12 system features desired by surgeons for a platform to integrate PROMs into clinical use. These were further grouped into four unique overarching themes. Surgeons asserted that the platform must (1) be user-friendly, (2) promote information transparency, (3) incorporate validated questionnaires while still allowing for some degree of customizability, and (4) support the collection and display of longitudinal data.

Conclusions Health care systems planning to develop a platform to integrate PROMs into their clinical practices should investigate the feasibility of the system features identified as essential by this study. While surgeons represent an important stakeholder group when designing a new platform for use in surgical practice, it will also be crucial to explore the features desired by patients before designing or adopting a platform for clinical use.

trovo alpujarreño:
Authors: Flores Sánchez Manuel , Del Campo Tejedor Alberto
Published: July 2023

La costumbre alpujarreña de improvisar versos satíricos es aquí interpretada como un «arma de los débiles, en el sentido de James C. Scott, es decir, una forma de resistencia oblicua y desorganizada que fue útil especialmente durante el franquismo. Fustigando a todo aquel que incumpliera los preceptos de reciprocidad y redistribución, los troveros reivindicaban una «economía moral» (Thompson), típica de un contexto campesino de carestía donde florecía la concepción del «bien limitado» (Foster). Se argumenta que estos tres conceptos, clásicos en ciencias sociales, permiten comprender tanto la utilidad del trovo alpujarreño durante la vigencia del sistema alpujarreño tradicional, como su declive en una economía de libre mercado bajo un estado centralizador, donde disuelven los anclajes de la cultura cortijera, incluyendo la ligazón e interdependencia entre los sujetos, la identificación de las desigualdades en el plano local-comarcal o ciertos modelos masculinos de rebeldía.

Objectives. To compare the mortality of unvaccinated oncology patients who received chemotherapy or immunotherapy during the pandemic with those treated before the pandemic. Materials and methods. We conducted a cohort study in four tertiary hospitals in Argentina. Outpatients with a solid neoplasm of any stage on cytotoxic or intravenous immune therapy were eligible. The pandemic cohort was enrolled during the initial phase of the outbreak and compared with a cohort from a pre-pandemic period using propensity score matching (PSM). Subjects were matched for age, sex, health insurance, severe COVID-19 complications risk, performance status, cancer and treatment type, treatment line, and body mass index. All-cause mortality was estimated in both cohorts after the 6-month follow-up. Results. Out of 169 patients recruited between April and August 2020 to the pandemic and 377 to the pre-pandemic cohorts in the same period of 2019, 168 were matched. After PSM, all-cause mortality was 17.9% in the pandemic and 18.5% in the pre-pandemic cohort, Risk Ratio: 0.97 (95% confidence interval: 0.61-1.52, p=0.888). In the pandemic cohort, 30/168 patients died - none of them from COVID-19 infection. Conclusions. We failed to demonstrate an increment in the mortality of unvaccinated, ambulatory patients on active intravenous anticancer treatment exposed to the COVID-19 pandemic.

Hospitalization-associated disability prediction using Hospital Frailty Risk Score in older patients undergoing pancreatectomy
Authors: Tatsuro Inoue , Momosaki Ryo , Shimizu Akio , Maeda Keisuke
Published: July 2023

Purpose
Frailty and hospitalization-associated disabilities (HAD) are geriatric conditions that should be managed in older patients undergoing pancreatectomy. The Hospital Frailty Risk Score (HFRS) can evaluate frailty based on the medical records and could predict postoperative activities of daily living (ADL) decline. This study aimed to investigate whether the HFRS affects the postoperative incidence of HAD in older patients who underwent pancreatectomy.
Methods
This retrospective, observational study used data from a nationwide hospital-based database. We included consecutive patients aged ≥ 65 years who were diagnosed with pancreatic cancer (International Statistical Classification of Diseases, 10th revision code C25) and underwent curative pancreatectomy between April 2014 and August 2020. We evaluated preoperative frailty using HFRS. The primary outcome was HAD following pancreatectomy. Logistic regression analysis was performed for analyzing the impact of frailty on HAD following pancreatectomy.
Results
We included 671 patients for the analysis (mean age 74.3 ± 5.6, male 54.8%). The prevalence of intermediate and high risk of frailty with HFRS ≥ 5 was 2.7%. The incidence of HAD was significantly higher in the intermediate- and high-risk groups compared to that in the low-risk group (33.3% vs. 8.4%, p < 0.001). Logistic regression analysis demonstrated that intermediate and high risks of frailty increased the likelihood of HAD (odds ratio,3.55; 95% confidence interval:1.12 11.2).
Conclusions
The risk of frailty evaluated using the HFRS increased the likelihood of developing HAD in older patients undergoing pancreatectomy. Future research on effective perioperative interventions for preventing postoperative HAD and enhancing postoperative ADL recovery is warranted.

Among organic phase change materials, paraffin is most commonly used,
but it is not environmentally friendly due to its petrochemical content.
For efficient utilization of solar or thermal energy, new phase change
materials are urgently needed, or it is necessary to improve the thermal
properties of existing materials. Therefore, the utilization of lamb’s
tail fat as a latent heat storage material is of particular importance
for the evaluation of bio based waste oils. T-history is one of the
simplest and most reliable and the simple equipment setup and reliable
results make the T-History method attractive. In this study, new phase
change materials were improved by using different concentrations of
cyclophosphazene derivatives as an additive to the starting lamb tail
fat material. According to the results, 1% HEHCP-doped lamb tail fat
can be proposed for application in thermal energy storage systems when
used for insulation. In addition, it is found that if the phase change
materials developed by inclusion of HBACP can be operated as cooling
liquid for photovoltaic panels or as working fluid in concentrated solar
power systems, owing to higher fusion of heat value of 1% HBACP and
higher specific heat capacity of 2% HBACP consisting lamb tail fat.

В современном мире китайцы становятся одной из наиболее многочисленных этнических групп, которые проживают за пределами родной страны. Китайцы являются второй по величине диаспорой в мире, уступая только индийцам. Согласно данным Китайского государственного совета по развитию и исследованию философии и социальных наук, на конец 2020 года в мире проживало около 60 млн. китайских граждан, которые имеют статус мигрантов или находятся за границей временно. Одним из самых популярных направлений миграции китайцев является Россия. Согласно данным Федеральной миграционной службы, на конец 2020 года в России проживало более 200 тыс. китайских граждан. Этот факт говорит о значимости и актуальности изучения китайской диаспоры в России. Существующие базы данных по китайским эмигрантам в России на русском языке являются недостаточными и несистематизированными. Данная проблема затрудняет понимание реальной картины социальноэкономической ситуации китайской диаспоры в России и затрудняет организацию мероприятий, направленных на поддержку и адаптацию китайских эмигрантов. В связи с этим, целью нашего исследования является создание тематической базы данных китайских эмигрантов в России на русском языке. Данная база данных будет включать в себя информацию о китайских эмигрантах, проживающих в России, и содержать различные категории информации, такие как основные данные, информация о работе, образовании, языковых знаниях, культурных особенностях и планируемых бизнес-проектах.

In the modern world, the Chinese are becoming one of the most numerous ethnic groups that live outside their native country. The Chinese are the second largest diaspora in the world, second only to the Indians. According to the Chinese State Council for the Development and Research of Philosophy and Social Sciences, at the end of 2020, there were about 60 million Chinese citizens living in the world who have the status of migrants or are temporarily abroad. One of the most popular destinations for Chinese migration is Russia. According to the Federal Migration Service, at the end of 2020, more than 200 thousand Chinese citizens lived in Russia. This fact speaks about the importance and relevance of studying the Chinese diaspora in Russia. The existing databases on Chinese emigrants in Russia in Russian are insufficient and unsystematic. This problem makes it difficult to understand the real picture of the socio-economic situation of the Chinese diaspora in Russia and makes it difficult to organize events aimed at supporting and adapting Chinese emigrants. In this regard, the purpose of our research is to create a thematic database of Chinese emigrants in Russia in Russian. This database will include information about Chinese emigrants living in Russia and contain various categories of information, such as basic data, information about work, education, language knowledge, cultural characteristics and planned business projects.

Roads are infrastructure that has a vital role for the community in supporting social and economic activities. Therefore, appropriate handling information is needed for road maintenance and improvement to be on target. One of the methods used is the International Roughness Index (IRI) method with the help of the Road bump application. The purpose of this study is to analyze and recommend handling road surface conditions, as well as to test the validity of the Road bump application with a Laser Profilometer. This research was conducted on the 10 KM section of Trans Kalimantan Road. Comparative data is obtained from secondary data issued by BPJN in 2021 using the Laser Profilometer tool. This study found that the condition of the Trans Kalimantan Road was 80% in the excellent category, 18% in the moderate category, and 2% in the slightly damaged category, and had similarities with the BPJN IRI value of 95%. Road bump also tends to the IRI value to be greater than the BPJN IRI value. Based on the results of this study, the Road bump application can be used as an alternative tool for measuring road surface conditions using the International Roughness Index (IRI) method.

Published: July 2023

La fresa es una fruta de gran importancia a nivel global gracias a sus propiedades organolépticas y nutricionales. Sin embargo, su vida útil es corta, incluso en refrigeración, debido a su alta tasa de respiración y susceptibilidad al ataque de hongos. Este hecho dificulta el transporte de la fresa desde el sitio de producción/procesamiento hasta el consumidor. Se ha demostrado que el ozono es un gas con propiedades antimicrobianas que puede prolongar la vida útil de la fresa. El objetivo de esta revisión fue investigar los avances en la aplicación de ozono en fresas como tecnología postcosecha y su impacto en la calidad microbiológica del fruto. Se revisaron artículos publicados en los últimos diez años que investigan la aplicación de ozono para reducir la carga microbiológica en fresa. Los resultados de los trabajos revisados demuestran que el tratamiento postcosecha con ozono puede usarse para prolongar su vida útil y proteger a la fresa de la contaminación microbiana. Se recomienda realizar un estudio previo de las condiciones de tratamiento para cada producto potencialmente tratable con ozono, así como realizar un análisis integral del sistema de gestión del producto para lograr un mayor impacto y factibilidad de aplicación de esta tecnología postcosecha.

Ecoenzyme is widely recognized as a multipurpose solution made from fermented sugar with vegetable and or fruit residue. This study aims to determine the effect of ecoenzyme solutions on the growth of Impatiens balsamina L. plants. This study followed a completely randomized design (CRD) with one factor. The data obtained were then analyzed by means of analysis of variance (ANOVA) in a one-factor completely randomized design and followed by the Duncan Multiple Range Test (DMRT) with a 95% confidence level. The results showed that on the parameters of leaf and stem length, watering with the addition of ecoenzyme had a significant effect on the growth of balsam plants starting at 30-day after culturing (DAC) and 51-DAC. Anatomical analysis of the root, stem and leaf of balsam plant treated with watering using the addition of ecoenzyme solution showed that there were significant differences with the control. The results of this study are expected to increase knowledge related to the propagation of balsam plants and the use of ecoenzyme as liquid organic fertilizer.

Introduction

The human respiratory syncytial virus (hRSV) is responsible for most respiratory tract infections in infants. Even though currently there are no approved hRSV vaccines for newborns or infants, several candidates are being developed. rBCG-N-hRSV is a vaccine candidate previously shown to be safe in a phase I clinical trial in adults (clinicaltrials.gov identifier #NCT03213405). Here, secondary immunogenicity analyses were performed on these samples.

Methods

PBMCs isolated from immunized volunteers were stimulated with hRSV or mycobacterial antigens to evaluate cytokines and cytotoxic T cell-derived molecules and the expansion of memory T cell subsets. Complement C1q binding and IgG subclass composition of serum antibodies were assessed.

Results

Compared to levels detected prior to vaccination, perforin-, granzyme B-, and IFN-γ-producing PBMCs responding to stimulus increased after immunization, along with their effector memory response. N-hRSV- and mycobacterial-specific antibodies from rBCG-N-hRSV-immunized subjects bound C1q.

Conclusion

Immunization with rBCG-N-hRSV induces cellular and humoral immune responses, supporting that rBCG-N-hRSV is immunogenic and safe in healthy individuals.

Published: July 2023

A 10-year-old, male-neutered, domestic short-hair cat was examined at the Veterinary Health Center Emergency Service at Kansas State University for a one-day history of dyspnea. Prior to thoracocentesis, sedation was provided. The cat stopped breathing after sedation and went into cardiac arrest. Cardiopulmonary resuscitation (CPR) was unsuccessful. At necropsy, there was severe pleural effusion and bilateral pulmonary atelectasis. The myocardium of the atria and ventricles, and tunica adventitia of coronary vessels, pulmonary artery, and aorta, had pale, firm, multinodular masses ranging from 0.3 to 0.5 cm in diameter. Multiple nodules were also present in the liver. Multifocally expanding the epicardial fat and compressing the underlying epicardium, infiltrating, and expanding the myocardium, and expanding the walls of major vessels, there was a multinodular, unencapsulated, densely cellular neoplasm composed of polygonal epithelial cells arranged in nests and packets and supported by a fine fibrovascular stroma. The nodules in the liver had similar histologic features. In this case, neoplastic cells at the primary and metastatic sites were intensely immunoreactive to synaptophysin, variably reactive to chromogranin A, and negative for neuron specific enolase, cytokeratin, vimentin, thyroglobulin, and smooth muscle actin. The gross, histologic, and immunohistochemical findings support the diagnosis of chemodectoma, with metastases to the liver. Synaptophysin and chromogranin A were the most useful immunohistochemical markers to diagnose malignant chemodectoma in this cat.

Examination of hemoglobin levels before blood donation is an important check to certify that potential donors can donate blood. Hemoglobin levels can be measured using the hematology analyzer method where this method checks more quickly and the results issued usually have gone through quality control carried out by an in-house laboratory, it's just that this method has limitations including treatment, room temperature, must be controlled periodically. Checking hemoglobin levels can also be measured using the Hb meter method. Checking hemoglobin levels can also be done using Hb meters which are widely used by health services, such as clinical laboratories, health centers and hospitals. The advantages of the Hb meter include the results obtained faster and cheaper. This study aims to determine differences in the results of examination of hemoglobin levels using the Hb meter method with a hematology analyzer. The research method used is True Experiment with the type of research The Posttest Only Design. The sample in this study were 16 prospective blood donors at PMI Yogyakarta City. Respondents who had been given an explanation and signed an informed consent were then taken a sample of their venous blood and examined the hemoglobin level using the Hb meter and hematology analyzer methods. results are recorded and then data processing is carried out using univariate analysis and bivariate analysis. Based on the results of the study it was concluded that there was no significant difference between the results of examining hemoglobin levels using the Hb meter method and the Hematology Analyzer (p = 0.321 : p > 0.05). The average value of hemoglobin levels in the Hb meter method is 14.631 g/dl while the average value of hemoglobin levels in the Hematology Analyzer method is 14.294 g/dl.

Objetivo: Avaliar a influência de líquidos modeladores na resistência à compressão de 2 resinas compostas. Material e métodos: foram utilizadas as resinas compostas Vittra (FGM, Joinville, Brasil), Charisma (Kulzer, São Paulo, Brasil) e o líquido modelador Signum liquid (Kulzer, São Paulo, Brasil). Foram confeccionadas 40 amostras utilizando uma matriz de silicone, onde cada amostra tinha 3 mm de espessura, 5mm de diâmetro, com formato cilíndrico, estas foram divididas em 4 grupos (n=10): grupo 1- amostras Vittra sem modelador, grupo 2 - amostras Vittra com modelador, grupo 3 - amostras Charisma sem modelador e grupo 4 - amostras Charisma com modelador. Nas amostras que utilizaram o modelador, o líquido modelador foi pincelado entre as camadas e na parte superficial da última camada. Estas amostras foram submetidas a uma máquina de ensaio universal, Emic DL-20.000, para o teste de resistência à compressão. Resultados: as médias de resistência à compressão foram grupo 1 - 14870,1N, grupo 2 - 13552,4N, grupo 3 - 14322,9N e do grupo 4 - 14923,3N, estes resultados foram analisados estatisticamente através do teste ANOVA com um valor de p=0,05 e comparados entre as resinas compostas do mesmo fabricante e diferentes fabricantes com e sem modelador. Através da análise estatística não houve diferença significante quanto à utilização, valor de p=0,10, ou não do líquido modelador de resina composta, valor de p=0,57. Conclusão: a presença do líquido modelador entre as camadas de compósitos, em ambas resinas testadas, não apresenta influência na resistência à compressão.

Післявоєнне відновлення енергетичної галузі України потребує, зокрема, впровадження інноваційних технологій на основі екологічно чистих відновлюваних джерел енергії. Одним із перспективних напрямів створення децентралізованих систем опалення невеликих міст, поселень та окремих об’єктів різного призначення є застосування комплексних енергосистем на основі низькопотенціальної геотермальної та сонячної теплової енергії. Актуальною задачею під час проєктування комплексних локальних систем (кластера) енергозабезпечення з використанням відновлюваних джерел енергії є створення ефективної системи управління. В умовах сьогодення такі системи мають будуватися на основі відповідної елементної бази, сучасної мови програмування, чутливих вимірювальних приладів та ефективних алгоритмів оцінки та прийняття рішень. У роботі представлено діючий макет розробленої й сконструйованої в Інституті відновлюваної енергетики НАН України експериментальної гідротермальної теплонасосної системи, до складу якої входять: система забору низькопотенціальної теплової енергії, тепловий насос, геліосистема та акумулятори теплової енергії. Визначено основні недоліки системи та запропоновані енергоефективні технічні та організаційні рішення. З метою підвищення ефективності роботи кластера розроблена система управління, яка складається з основного модуля та модулів управління окремими підсистемами, функціонально поєднаних між собою. Виконано опис кожного функціонального блока системи. Зроблено висновки, щодо необхідності проведення експериментальних та аналітичних досліджень ефективності застосування запропонованої системи управління кластером, де як джерело відновлюваної теплової енергії використовується низькопотенціальна геотермальна теплота та енергія сонячного випромінювання. Робота проведена в межах виконання науково-дослідного проєкту: «Розроблення енергетичних кластерів для забезпечення об’єктів багатоцільового призначення електричною та тепловою енергією з використанням технологій відновлюваної та водневої енергетики (шифр: «Енергогарант»)».
