Iron, Copper, and Zinc Homeostasis in the Battle between Macrophage and Mycobacterium Tuberculosis
Authors: Yang Zisha , Zhang Li , Wang Yan , Pi Jiang , Peng Duo , Yao Yunhong , Xu Junfa , Zhao Yi
Published: January 2024

Iron, copper, and zinc play integral roles in the battle against Mycobacterium
tuberculosis (Mtb) infection; however, they are often trapped between nutrients and
toxins, posing a significant challenge to macrophages and Mtb to utilize them. Due to
this two-sided effect, macrophages and Mtb strictly regulate metal uptake, storage, and
excretion. This review discusses the balanced regulation of iron, copper, and zinc in
macrophages and Mtb during infection, focusing on the intracellular metal regulatory
system. Macrophages typically use the two-sided effect of metals to limit Mtb access to
nutrients or poison them. Mtb has developed a metal metabolism regulatory mechanism
compatible with the nutritional immune strategy. This includes the mediation of relevant
metalloproteins and metalloenzymes to maintain the multimetal balance. This review also
explored the regulation of metal metabolism homeostasis in macrophages resistant to
Mtb infection, providing a theoretical foundation for identifying potential clinical targets
for Mtb infection, developing metalloid anti-tuberculosis drugs, and understanding the
immune mechanisms against intracellular Mtb infection.

:

The second most prevalent cause of fatalities globally is malignant tumors. The avoidance
and therapy of cancer proliferation still have many prospects for betterment despite enormous advancements.
Chemotherapy can occasionally have a lot of unfavorable adverse reactions. Novel
agents from botanicals, especially the use of cancer therapeutic ingredients, may decrease negative
consequences. There are currently several products from plants used for fighting cancer. However,
numerous plant chemicals have not yet been examined in people but show extremely encouraging invitro
anti-cancer properties. Further research is required to determine whether these plant chemicals
are beneficial in treating human cancers. The present work has focused on the various traditional
herbal remedies and the phytochemicals that exhibited promising anticancer impact. The desirable
activity may be due to novel agents isolated from plant sources. The present investigations address
natural ingredients for cancer treatment and chemoprevention that are now being used in clinical settings
and/or are undergoing clinical studies. Potential research concentrating on naturally anticancer
drugs can create an entirely novel avenue in the fight against cancer that could significantly boost the
chance of survival for cancer patients.
Protective Assessment of Novel (Bncs Formulation) against Brain Tumor
Authors: Mishra Anuradha , Ahmad Afza , Ansari Irfan Ahamad , Tiwari Rohit Kumar
Published: January 2024

Background:

Oxidative stress refers to non-homeostatic elevation within intracellular
reactive oxygen species (ROS) levels and is associated with several neuro-related pathological
conditions. Diclofenac is a commonly prescribed non-steroidal anti-inflammatory drug
(NSAID) for treating aches and pain by reducing inflammation. Diclofenac is also associated
with the induction of apoptotic cell death by altering the homeostatic balance within mitochondria.
In the present report, the neuroprotective effects of BNC formulation constituted by Bacopa
monnieri leaves, Nigella sativa and Curcuma longa rhizome seeds were investigated.

Methods:

The synthesized formulation was characterized using FT-IR and LC-MS along with
organoleptic evaluation. Thereafter neuroprotective efficacy of BNC formulation was subsequently
investigated against Diclofenac-induced oxidative stress in SH-SY5Y cells. The cells
were pretreated with synthesized formulation and subsequently evaluated for amelioration in
Diclofenac-induced cytotoxicity, and ROS augmentation. The neuroprotective effect of synthesized
formulation was further explored by evaluating the changes in nuclear morphology, and
apoptosis alleviation with concomitant regulatory effects on caspase-3 and -9 activation.

Results:

Diclofenac was found to be considerably cytotoxic against human neuroblastoma SHSY5Y
cells. Intriguingly, Diclofenac-mediated toxicity was reduced significantly in SH-SY5Y
cells pretreated with BNC formulation. Augmented ROS levels within Diclofenac-treated SHSY5Y
cells were also reduced in the BNC formulation pretreated SH-SY5Y cells. Furthermore,
BNC formulation pretreated SH-SY5Y cells also exhibited reduced dissipation of mitochondrial
membrane potential, caspase-3 and -9, along with apoptosis after Diclofenac treatment.

Conclusion:

These findings indicated that, indeed, Diclofenac induces considerable ROSmediated
apoptosis in SH-SY5Y cells, which further intriguingly ameliorated Diclofenacmediated
cytotoxic effects on SH-SY5Y cells. This manuscript further collected information
about available National and International patents published or granted in preparation of and
thereof applications against motor and non-motor brain dysfunctions.

Teachers’ Perceptions of Integrating Tower Gardens into Pre-K4 Curriculum
Authors: Sills Kaitlyn , Stapp Alicia , Lambert Laurel , Wolff Kenya
Published: January 2024

Schools play an integral role in providing opportunities for children of all ages to be exposed to nutrition education. There are a variety of ways children can receive nutrition education in the school setting, such as explicit lessons, modeled dialogue, and exposure to nutrition-based principles. However, there continues to be a disconnect between teacher perceptions of nutrition education and time spent implementing it in the classroom. Nutrition education can come in many forms, including hands-on gardening and explicit discussions on the impact of food choices on overall health. Effective nutrition education in any form elicits numerous benefits for children, but there are a multitude of barriers that inhibit teachers from implementing hands-on gardening into their classrooms—such as time, space, and teacher self-efficacy. Tower Gardens, otherwise known as hydro- and aeroponic, vertical gardening systems, offer an alternative to the space and time required for traditional gardening. Nonetheless, the body of literature surrounding the impact and feasibility of implementing tower gardening systems is limited, specifically in the preschool setting. Therefore, this study explored teachers’ perceptions of and experiences with implementing Tower Gardens into pre-kindergarten 4-year-old (pre-K4) classrooms. A qualitative approach was employed wherein a focus group was conducted with pre-K-4 teachers who integrated Tower Gardens through the Growing Healthy Minds, Bodies, and Communities Curriculum. Findings were analyzed and four themes emerged as follows: (a) novelty of Tower Gardens increases opportunities to learn; (b) a multitude of interactions with growing and food; (c) increased engagement from children; and (d) implementation and positive outcomes for teachers. These findings suggest that Tower Gardens can be implemented with relative ease in the classroom and produce positive outcomes for student engagement and interactions with foods.

Assessing the ability of a large language model to score free text medical student notes (Preprint)
Authors: Burke Harry B , Hoang Albert , Lopreiato Joseph O , King Heidi , Hemmer Paul , Montogmery Michael , Gagarin Viktoria
Published: January 2024

BACKGROUND

Teaching medical students the skills required to acquire, interpret, apply, and communicate clinical information is an integral part of medical education. A crucial aspect of this process involves providing students with feedback regarding the quality of their free-text clinical notes.

OBJECTIVE

The objective of this project is to assess the ability of ChatGPT 3.5 (ChatGPT) to score medical students’ free text history and physical notes.

METHODS

This is a single institution, retrospective study. Standardized patients learned a prespecified clinical case and, acting as the patient, interacted with medical students. Each student wrote a free text history and physical note of their interaction. ChatGPT is a large language model (LLM). The students’ notes were scored independently by the standardized patients and ChatGPT using a prespecified scoring rubric that consisted of 85 case elements. The measure of accuracy was percent correct.

RESULTS

The study population consisted of 168 first year medical students. There was a total of 14,280 scores. The standardized patient incorrect scoring rate (error) was 7.2% and the ChatGPT incorrect scoring rate was 1.0%. The ChatGPT error rate was 86% lower than the standardized patient error rate. The standardized patient mean incorrect scoring rate of 85 (SD 74) was significantly higher than the ChatGPT mean incorrect scoring rate of 12 (SD 11), p = 0.002.

CONCLUSIONS

ChatGPT had a significantly lower error rate than the standardized patients. This suggests that an LLM can be used to score medical students’ notes. Furthermore, it is expected that, in the near future, LLM programs will provide real time feedback to practicing physicians regarding their free text notes. Generative pretrained transformer artificial intelligence programs represent an important advance in medical education and in the practice of medicine.
Differential Diagnosis Assessment in Ambulatory Care with a Digital Health History Device: Pseudo-randomized Study (Preprint)
Authors: Healey Beth , Spechbach Herve , Schwitzguebel Adrien
Published: January 2024

BACKGROUND

Digital health history devices (DHHDs) represent a promising wave of digital tools with the potential to enhance the quality and efficiency of medical consultations. They achieve this by providing physicians with standardized, high-quality patient history summaries and facilitating the development of differential diagnoses (DD) prior to consultation and make the patient feel involved in this process.

OBJECTIVE

This study focuses on evaluating the efficacy of one such DHHD, 'DIANNA,' in compiling appropriate lists of DDs within the outpatient setting.

METHODS

A pseudo-randomized controlled trial involved 101 patients seeking care at the University Hospital Geneva emergency outpatient department, presenting a range of conditions affecting the limbs, back, and chest. The initial 51 patients were assigned to the control group, while the subsequent 50 formed the intervention group. In the control group, physicians were tasked with establishing an extensive DD list based on traditional history-taking and clinical examination. Conversely, in the intervention group, physicians had the advantage of reviewing the DIANNA report, which included suggested DDs, before interacting with the patient. In both groups, a senior physician independently reviewed the patient and formulated a DD list, serving as the 'gold standard' for comparison.

RESULTS

The study findings showcased a notable improvement in DD accuracy when DIANNA was employed (mean 79.3%, SD 24%), as compared to the control group (mean 70.5%, SD 33%; P=.014). Subgroup analysis further elucidated this enhancement, with an 8% difference in favor of the intervention group for low complexity cases (1-2 possible DDs; P=.08). This advantage expanded to 17% for intermediate complexity cases (3 possible DDs; P=.03), while high complexity cases (4-5 possible DDs) saw a 15% increase (P=.92). DIANNA was found to effectively determine appropriate DDs in 81.6% of cases, and physicians recognized its assistance in establishing the correct DD in 26% of instances.

CONCLUSIONS

The study conclusively affirms the effectiveness of DIANNA in supporting physicians to formulate more precise DDs. This underscores the potential of DHHDs like DIANNA to enhance clinical decision-making and improve the accuracy of patient diagnoses in the medical field.

CLINICALTRIAL

This trial was registered on clinical trials (NCT03901495).

Published: January 2024

Previously, we showed that Anti-Terrorist Operation (ATO) participants had significant complaints of vestibular disturbances, objective and subjective vertigo, kinetosis. One hundred and ten patients were examined, including 65 participants of ATO with mild traumatic brain injury (mTBI), 44 non-ATO without mTBI. The questionnaire “Types of dizziness” was used according to the International Clinical Protocol for Vertigo Disorders (Dizziness). Complaints of optokinetic nystagmus (OKN) were found in 27 (43.08 %) ATO and 7 (15.91 %) non-ATO patients, F-test = = 0.04, T-test = 0.0026. Thus, complaints of OKN turned out to be a specific feature of patients with blast injury syndrome. Complaints of nausea were detected in 38 (58.46 %) ATO and 11 (25.00 %) non-ATO patients, F-test = 0.38, T-test = 0.00035, indicating that this complaint is present and quantitatively more pronounced in ATO patients, but it is not specific for patients with mTBI. Complaints of vomiting were found in 19 (29.23 %) ATO and 11 (13.64 %) non-ATO patients, F-test = 0.055, T-test = 0.046, showing that this complaint is not typical for patients with mTBI. Complaints of anxiety without a reason were detected in 35 (53.85 %) ATO and 15 (34.09 %) non-ATO patients, F-test = 0.75, T-test = 0.041. Thus, this complaint is present and quantitatively more significant in ATO patients. Complaints of blackout were found in 41 (63.08 %) ATO and 16 (36.36 %) non-ATO patients, F-test = 0.98, T-test = 0.006, demonstrating that this complaint is present and quantitatively more pronounced in ATO patients, but it is not specific for patients with mTBI. Complaints of depression and numbness did not differ reliably according to the statistical indicators used. There were certain correlations. OKN: with scotomas in migraine headaches, kinetoses, descendophobia, and nyctophobia. Nausea: with severity of dizziness, vomiting episodes, blackouts, migraine headaches, increased heart rate, kinetoses, nyctophobia, claustrophobia. Vomiting: with ascendophobia, migraine headaches, increased heart rate. Anxiety without a reason: with impaired movement coordination, depression, blackouts, hyperacusis, weather sensitivity, ascendophobia. Depression without a reason: with subjective vertigo, agoraphobia, blackouts, numbness, throbbing headaches, weather sensitivity, electromagnetic hypersensitivity, increased heart rate. Blackouts: with weight gain, objective vertigo, orthostatic and throbbing headache. Numbness: with dizziness and its severity, agoraphobia, ascendophobia, migraine headaches and increased heart rate. Correlations are discussed from the point of view of vestibular dysfunction.

Authors: Yasnii O.M. , Lebedynets D.V. , Trishchynska M.A.
Published: January 2024

Acute stroke is a major public health problem in both developing and developed countries and has detrimental effects on the individual, family, and societal levels. Ischemic stroke is a disease with significant prevalence, high disability, high mortality, and high recurrence rate. Diabetes mellitus is one of the most serious and most common chronic diseases today, causing life-threatening complications that lead to disability. Among these complications, one of the most common is acute stroke. People with diabetes are at a 1.5–2 times higher risk of acute ischemic stroke compared to people without this disease. Hyperglycemia doubles the risk of recurrent stroke and increases the risk of death or disability after ischemic stroke. There are several possible mechanisms by which diabetes leads to acute stroke, including cardiac embolism (atrial fibrillation), endothelial dysfunction, increased arterial stiffness at an early age, systemic inflammation and thickening of the capillary basement membrane. Controlling glucose levels through lifestyle changes or medications and modifying other associated risk factors (such as hypertension and dyslipidemia) are critical steps to the effective stroke prevention.

Published: January 2024

Questões relativas ao acesso regular à água potável e segura têm causado preocupação, trazendo a necessidade de contrapor e reavaliar a conceituação de disponibilidade de recursos hídricos relacionando-o a um conceito de escassez. Este estudo teve como objetivo analisar a situação de acesso à água pela população domiciliada no Bairro da Cremação, Belém-PA, por meio do Índice de Pobreza Hídrica (IPH). A metodologia foi composta por pesquisa bibliográfica seguida de levantamento de informações in loco através da aplicação de questionários. O IPH foi estruturado pelas componentes: Capacidade, Recursos Hídricos, Uso, Acesso e Meio Ambiente, os quais foram subdivididos em subcomponentes e variáveis. O bairro da Cremação apresentou o IPH médio de 6.46, resultado condizente com a realidade observada. Os principais problemas relatados foram a presença de cor e sabor na água e deficiências no sistema de saneamento básico, como o lançamento do esgoto doméstico na rede de drenagem e ocorrência de alagamentos devido à disposição inadequada dos resíduos sólidos. Pode-se concluir que o conceito de escassez hídrica na região não está relacionado a causas naturais, e sim principalmente à ineficiência dos gestores públicos e a falta de conhecimento e conscientização da comunidade.
DINÂMICA DA CONCENTRAÇÃO DE POLUENTES EM LAGOAS DE ESTABILIZAÇÃO TRATANDO LIXIVIADO DE ATERRO SANITÁRIO
Authors: Perotti Nathalia , Caetano Marcelo de Oliveira
Published: January 2024

Os aterros sanitários são unidades essenciais para o destino ambientalmente adequado de resíduos sólidos no atual modelo de gestão brasileiro. O processo de degradação biológica dos resíduos aterrados tem como produto um líquido percolado de composição e vazão variável, com alto potencial poluidor, denominado lixiviado. A especificidade das características do lixiviado torna-o de difícil tratabilidade, especialmente em processos biológicos. Nessa perspectiva, o presente estudo avaliou as características físico-químicas do lixiviado bruto, bem como a dinâmica dos poluentes em sistema de lagoas de estabilização, composto de Lagoa Anaeróbia, Lagoa Aerada 1, Lagoa Aerada 2 e Lagoa de Polimento de um Aterro Sanitário, a fim de determinar a eficiência do sistema. O estudo se deu através da análise estatística de dados existentes do ano de 2002 a 2017, realizada através de análise de variância (ANOVA) seguida pelo teste de Tukey, resultado do monitoramento da Estação de Tratamento de Lixiviado. Os resultados exibidos em gráficos box plot apresentaram as concentrações de parâmetros ao longo do tratamento, demonstrando que o sistema apresentou eficiência de remoção média de 58.9% de DBO5,20, 50.9% de DQO, 37.4% de Nitrogênio amoniacal e 53.1% de Nitrogênio Total. Em relação à série de sólidos, o sistema obteve baixo desempenho. Dos elementos-traço, apenas o Pb apresentou variação significativa evidenciada pelo ANOVA, considerando p<0,05. Em geral, o teste de Tukey (p<0,05) demonstrou que não há alterações significativas nas concentrações entre as unidades de tratamento.

Published: January 2024

O grau de eutrofização de estruturas lênticas artificiais localizadas em região do semiárido brasileiro foi investigado. Foram considerados 14 reservatórios com coletas de amostras trimestralmente no período de 2015 a 2021. As variáveis de estudo compreenderam a fração de volume disponível (VD) no dia de coleta, pluviometria (PP), nitrogênio total (N), fósforo total (P), clorofila a (Cla), transparência (Z) e densidade de cianobactérias (CB). Foi determinado o Índice de Estado Trófico (IET) nos reservatórios. Também, entre as informações do estudo efetuaram-se análise bivariada (através de correlações) e multivariada (através de Análise de Componentes Principais).  Os valores de IET mostram carácter Eutrófico e que os resultados anuais podem ser baseados em média aritmética ou geométrica. As variáveis de associação climática (VD e PP) apresentaram efeito negativo sobre o acúmulo de nutrientes, com consequente incremento de eutrofização. A análise multivariada sugere resultados semelhantes. Entretanto, fenômenos no interior dos reservatórios parecem ser mais fortes que os de clima. Os resultados mostraram que a densidade de cianobactérias é potencializada por razões N:P < 20 e tem associação não relevante com as variáveis climáticas.

Este trabalho tem por objetivo propor um conjunto de indicadores baseado nos problemas relacionados ao gerenciamento e manejo das águas pluviais urbanas para auxiliar na tomada de decisão municipal, para a realidade brasileira, aplicado a municípios com até cem mil habitantes. Para atingir este objetivo foram identificados os problemas relacionados ao gerenciamento e manejo de águas pluviais urbanas, foi estruturado um conjunto de indicadores simples, foram relacionados os indicadores simples e os problemas, de forma sistematizada e, por fim, foi realizada a validação. O conjunto de indicadores desenvolvido possui 42 indicadores simples com capacidade de identificar 88.14% do total de 59 problemas listados relacionados ao gerenciamento e manejo de águas pluviais urbanas. A validação da sistematização apresentou resultados satisfatórios, no entanto, a carência de informações e dados ainda é um fator limitante para que ferramentas de gerenciamento de águas pluviais no Brasil sejam aprimoradas e amplamente utilizadas.
ONSITE SANITATION GOVERNANCE TOOLS FOR SMALL MUNICIPALITIES – FIRST STEPS FROM SANTA CATARINA STATE, SOUTH BRAZIL
Authors: Trevisan Alexandre Bach , Pereira Luciane Dusi , Sezerino Pablo Heleno
Published: January 2024

Promoting sanitation solutions are more than just choosing the right technology. The need for stakeholders’ cooperation and engagement challenges small municipalities to consider fecal sludge management (FSM) and simplified sewerage approaches, not only conventional systems, promoting a flexible suite of services and emerging governance discussion in this complex scenario. In this paper, we conducted 10 semi-structured key informant interviews (KII) and show 15 implemented governance tools in 5 municipalities with less than 10,000 inhabitants, in Santa Catarina State, in the Brazilian southern region. None of the researched municipalities showed a systematized framework and the governance structure is composed of dispersed tools, mainly developed in response to a public attorney, who acts as a blind sponsor of onsite solutions, calling other stakeholders for action. Onsite sanitation performs a relevant role to achieve service universalization, this paradigm shift requires a new governance structuring model that considers FSM as a part of this ecosystem seems to be the trail first step especially where the conventional approach does not always reach financial sustainability.

Logo, o estudo demonstrou que o adsorvente alternativo pode ser utilizado para remoção eficiente dos corantes em processo contínuo.
SENSORES DE MATERIAL PARTICULADO EN SUSPENSIÓN DE BAJO COSTO: INTEGRACIÓN AL MONITOREO DE LA CALIDAD DEL AIRE
Authors: Gomez Dario , Vassallo Julio
Published: January 2024

El avance del conocimiento sobre los efectos en salud que tienen las partículas atmosféricas, así como su influencia en el clima y potencial en calentamiento global, llevaron a exigir el control de sus niveles en el aire ambiente y a la determinación confiable de las concentraciones ambientales a nivel de superficie realizada en la mayoría de los países con instrumentos de referencia o equivalentes. Sin embargo, el costo y los recursos necesarios para la adquisición y operación de estos instrumentos de referencia dificultan la instalación de redes de vigilancia de la calidad del aire. En las últimas décadas, tuvo lugar a nivel internacional un gran desarrollo de sensores de los contaminantes atmosféricos que, a pesar de no ser reglamentarios, son portátiles, de menor costo y relativamente más sencillos de operar que los instrumentos de referencia. Los avances en microprocesadores y miniaturización permitieron el ingreso de estos sensores, facilitando un aumento inédito de su uso con fines no reglamentarios de evaluación de la calidad del aire. Aunque se acepta el empleo de sensores de bajo costo en el cuidado de la salud personal y pública, lo preocupante sobreviene cuando los datos obtenidos se emplean como sustitutivos o complementarios de las redes de referencia para vigilancia de la calidad del aire. El propósito de este artículo es contribuir a la discusión regional de criterios orientativos para el uso de sensores de partículas atmosféricas de bajo costo. El trabajo se basa en la revisión de medio centenar de artículos científicos publicados en la última década.
Development of Scientific and Technical Foundations for Improving Automated Control and Management Systems for Heat Supply Processes
Authors: Petrov A. M. , Popov A. N.
Published: January 2024

The scientific research is dedicated to the heat supply of the Norilsk industrial district and, primarily, takes into account the structural, technological, and other peculiarities of these systems' operations in the Arctic conditions. The distinctive features of the industrial district include the low temperature regime, with average annual temperatures below -15°C. These characteristics require the development of theoretical foundations for automated control of heat and power plants, optimizing the operational control of heat capacity and related technical systems, while considering the criteria of 'resilience' and 'reliability'. The scientific article considers the modeling and formalization of the design, development, and implementation processes of an automated system for operational control and management of heat capacity to manage heat supply processes in the Norilsk industrial district. The article examines the peculiarities of the district, including scattered settlements that together represent a single municipal entity, resulting in a complex technical infrastructure that is challenging both in terms of management and maintenance. The prerequisites for the emergence of such a unified system, related to the climatic characteristics of the district, are identified. The possibility of applying theoretical foundations for automated control of heat and power plants, taking into account recursive and continuous refined analysis of the functions of simulation models of heat supply system and heat and power plants, optimizing the operational control of heat capacity and related technical systems, while considering the criteria of 'resilience' and 'reliability', is considered. It is noted that the implementation of the proposed system will lead to the automation of operational control and management of heat capacity at the application level, as well as to the increased efficiency of the operation of heat and power plants and heat supply systems at a theoretical level, through diagnostic assessment of the state of objects and related technical systems.

Published: January 2024

The paper presents the research results of the underwater object identification method on the basis of periodogram analysis of hydroacoustic signals reflected from them with the application of voting algorithm. The identification of an object in the article means making a decision to distinguish it from other objects. Hydroacoustic signals are the main means of obtaining information about the underwater environment, they are also widely used to detect and identify underwater objects, including ships, submarines and underwater structures. The identification of underwater objects is an important task to ensure the safety of underwater exploration and the efficient utilization of marine resources in a noisy and complex underwater environment, including the presence of several natural objects and the use of various underwater exploitation techniques. The study proposes an approach that uses periodogram analysis followed by a voting algorithm to solve the problem of underwater object identification. Periodogram analysis is a method that identifies characteristic time and frequency features in hydroacoustic signals reflected from different types of objects. The proposed approach takes into account different characteristics of the signal periodogram to identify the unique features of each underwater object. The main purpose of this work is to develop and investigate a set of features using periodograms that take into account the specificity of hydroacoustic signals and the unique properties of different types of underwater objects under study. This approach allows to achieve a sufficiently high accuracy of identification. The paper presents the results of experiments conducted on real hydroacoustic signals. These results allow us to conclude about the effectiveness of the underwater object identification method by reflected hydroacoustic signals on the basis of periodogram analysis. The results of the study have practical significance and can be applied in applications related to underwater research.

The error of the proposed method was assessed by testing in media with known compressibility factors in a wide range of temperatures and pressures: air, nitrogen, argon, methane. The test results are presented in the form of experimentally obtained data deviations from the compressibility factor values published in literature. The air compressibility factor uncertain values obtained as a result of the study are in the range (-0.02 -0.07%), for nitrogen - (-0.06 - 0.02%), for argon - (- 0.04 - 0.04%), for methane - (-0.08 - 0.06%). The obtained empirical values are taken satisfactory with the information given in literary sources. The good agreement of the experimental and design data obtained for pure gases and air shows that the developed method of compressibility factor experimental determination is reliable, has the required accuracy and can be used to determine the natural gas compressibility factor of various component composition.
Socially Oriented Methodology Development to Determine Inventors’ Royalty

Published: January 2024

In this article, the authors consider a socially-oriented methodology to determine the amount of author's remuneration for service inventions, service utility models and service industrial designs. The peculiarity of the methodology is that, unlike well-known methods for calculating royalties, it is not related to the employee’s salary. The authors of the article noted that according to the methodology previously used in the USSR, the amount of remuneration for the use of an invention was determined by applying empirical coefficients that take into account the positive effect achieved, the volume of use, the complexity of the problem solved and significant differences in the technical solution. At the same time, Decree of the Government of the Russian Federation No. 1848 of November 16, 2020 establishes a socially unfair way of royalty determination, relating it to the amount of the employee’s monthly remuneration and not taking into account the real value of the invention. The proposed socially fair methodology for royalty determination implies the inclusion of a cost indicator to the empirical formula for the significance of an invention, based, in particular, on a study of the average salary of qualified engineers in the particular region. The developed methodology will make itpossible to motivate engineers-inventors for active and productive inventive activity, which will contribute to the growth of the number of high-tech enterprises in the Russian Federation and increase the efficiency of their economic activities. The proposed method of calculating royalties, includes two approaches to determine the effect of a technical solution (invention or utility model) in monetary terms. The technique can also be useful to organizations involved in scientific and technical development and invention, in particular regional branches of the All-Russian Society of Inventors and Innovators, when commercializing their innovative technical solutions.

The article presents a problem solution of plant cultivation automation using the Internet of Things concept. Using an intelligent system to control a hydroponics installation allows you to increase the energy efficiency of growing plants by introduction of intelligent technologies. The application of the Internet of Things concept allows a more qualitative approach to the search and application of methods of rational modern production. This concept allows the collected data to be Wi-Fi transferred from the microcontroller to a computer via a server, which is very effective in environments with large number of sensors. In this case, both time and material costs per share of production are significantly reduced. The work identified the requirements for a recording and control device in an intelligent system that connects to the Internet for further data processing, configuration and execution of the operating mechanism, and stages of operation of the growing system. Part of the control system for a plant cultivation complex using microcontroller devices available on the market, such as ESP, is considered. A constructive functional design of the device was developed. In addition, it was determined that the intelligent system contains the following modules: thing (the physical controller itself - device, peripherals), network (a network of devices and communication channels that ensure the transfer of information according to network protocols), cloud (includes a server that processes client, storage and web service requests). A description of the first module is given, which includes the main controller board with an esp12e microcontroller. The second module contains printed circuit boards for the power supply and controller, which were designed and laid out using the EasyEDA web service. For the third module, three-dimensional models of the power supply and main board were obtained in the EasyEDA web service environment.

Published: January 2024

The paper studies the effect of stiffeners in cross-section on the vibrations, barrel cooling, and firing accuracy. A quasi-one-dimensional mathematical model of barrel thermal conductivity is presented, taking into account the shape of the outer surface by the shape coefficient calculated on the basis of the perimeter of the barrel outer surface with stiffeners. When modeling the firing of a burst from a 30-mm cannon, the problem of internal ballistics was solved in a thermodynamic formulation, taking into account the distribution of the parameters of the gas-powder mixture along the length of the barrel and back pressure; in the time intervals between shots, the problem of gas outflow from the barrel was solved. Longitudinal-transverse vibrations of the barrel were calculated using a quasi-one-dimensional mathematical model. Boundary-value problems were solved using the integral-interpolation method. Cauchy problems were solved by the Runge-Kutta method. The permissible thickness of the barrel when fired is calculated. The results of modeling for a barrel with stiffeners are presented. It is shown that the amplitude of vibrations of a barrel with stiffeners is 36% less than the amplitude of vibrations of a cylindrical barrel. The spread of points of destruction when shooting at a vertical target at a distance of 1.5 km is reduced by 67%. The temperature of the outer surface of the barrel for each of 10 shots is reduced by 25% and when firing a burst of 100 shots it is reduced by 16%.
