МОЖЛИВОСТІ ХРОНОТЕРАПІЇ ЗАХВОРЮВАНЬ НЕРВОВОЇ СИСТЕМИ
Authors: Штробля А. , Бєлік Г.
Published: March 2023

Життєдіяльність організму – складна фізіологічна система органів, ритмічна активність якої знаходиться під впливом коливань процесів часу(день – ніч, пори року). Біологічні ритми – це еволюційний процес, "фізіологічний годинник" живого організму [1]. Біологічна ритмічність обумовлена ендогенно генетично закодованим молекулярним годинником організму, компоненти якого взаємодіють, щоб адаптувати циклічні зміни власне організму та його фізіологіч-ну активність з періодичністю дня та пори року [2]. По всьому тілу людини такий молекулярний годинник координує тимчасовий контроль функцій органів і тканин, регулюючи відповідні "програми" організму. Синхронність біоритмів між різними фізіологічними програмами організму (генераторами) значною мірою забезпечується нейронами, які безпосередньо реагують на певні сигнали навколишнього середовища.
РОЛЬ МЕЛАТОНІНУ ПРИ ПОРУШЕННЯХ ЦИРКАДІАННИХ РИТМІВ
Authors: Штробля А. , Серединська Н.
Published: March 2023

Циркадіанний ритм людини – один із обов’язкових складових в життєздатності організму. Фізіологічні ритми важливі для стабільності внутрішнього стану організму, так як забезпечують нормальну функцію органів у зв'язку з періодичними змінами навколишнього середовища і, таким чином, створюють умови адаптації організму. Яскравим прикладом цьому є  систематичний ритм сну та неспання, який пов'язаний з циркадіанними ритмами [1]. Основними регуляторами циркадіанних ритмів органів та систем організму є гіпоталамус і епіфіз через їх рецепторний зв’язок з мелатоніном [2]. У людей центральним водієм ритму циркадіанної системи є супрахіазматичні ядра (СХЯ) гіпоталамуса. Таким чином, основна роль в координації циклічних процесів в організмі належить циркадіанним коливанням функціональної активності нервової системи.

Propagating Sentinel-2 Top-of-Atmosphere Radiometric Uncertainty into Land Surface Phenology Metrics Using a Monte Carlo Framework
Authors: Graf Lukas , Gorroño Javier , Hueni Andreas , Walter Achim , Aasen Helge
Published: March 2023

Time series of optical image allow to derive land surface phenology metrics. These metrics are only complete with a statement about their uncertainty. A source of uncertainty is the radiometry of the sensor. We focused on Sentinel-2 MSI data since quantitative estimates of radiometric uncertainties are available. Uncertainties were propagated within a Monte-Carlo framework into the Normalized Difference Vegetation Index (NDVI), three-band Enhanced Vegetation Index (EVI) and Green Leaf Area Index (GLAI) derived from radiative transfer model inversion. In addition, we studied the effect of propagated uncertainties on scene pre-classification. Propagation was carried out for 34 scenes acquired for a crop growing season over an agricultural region in Switzerland using the TIMESAT approach for crop phenology estimation. Propagated uncertainties had little impact on the classification except for spectrally mixed pixels. Effects on the spectral indices and GLAI were more pronounced. In detail, GLAI was more uncertain due to the ill-posedness of radiative transfer model inversion (median relative uncertainty for all crop pixels and Sentinel-2 scenes: 4.4\%) than EVI (2.7\%) and NDVI (1.1\%). In crop phenology, phenological metrics exhibited largest uncertainties in the case of GLAI. The magnitude of uncertainty in the metrics depends on the error correlation between the scenes, which we assumed to be either zero (uncorrelated) or one (fully correlated) since the actual degree of correlation is unknown. If uncertainties are fully correlated, uncertainties in phenological metrics are small (2 to 3 days) but can take values up to greater 10 days under the uncorrelated assumption.
Improving the Representation and Extraction of Contact Information in Vision-based Tactile Sensors Using Continuous Marker Pattern
Authors: Li Mingxuan , Zhou Yen Hang , Li Tiemin , Jiang Yao
Published: March 2023

Tactile perception has been a hot topic of research in robotics. Robots sense the shape, material, distributed force, slip during contact, and use the multi-modal contact information to control grasping and manipulation. For vision-based tactile sensors, the contact representation and extraction determine the quality of the raw tactile information, and therefore serve a significant role in the robot perception system. This article highlights for the first time the importance of raw representation and extraction in visuotactile perception, and proposes a new multicolor CMP method for enhancing the performance of vision-based tactile sensors. Based on the principle of continuous marker pattern (CMP), the multicolor CMP method is optimized in the pattern and algorithm design. Regarding information representation, we present a new type of marker pattern based on RGB triangles and a preferred layout. In terms of information extraction, we propose a series of extraction strategies with the adaptive growing algorithm (AGA) and the spin-search algorithm (SSA) as the cores. The experiments reveal that the multicolor CMP method achieves improved precision and reliability compared to the former CMP method.
Abduction/Adduction Assistance from Powered Hip Exoskeleton Enables Modulation of User Step Width During Walking
Authors: Alili Abbas , Fleming Aaron , Nalam Varun , Liu Ming , Dean Jesse , Huang Helen (He)
Published: March 2023

Abstract-Using wearable robotics to modulate step width in  normal walking for enhanced mediolateral balance has not been  demonstrated in the field. We designed a bilateral hip exoskeleton  with admittance control to power hip abduction and adduction to  modulate step width. Objective: As the first step to show its potential, the objective of  this study was to investigate how human’s step width reacted to  hip exoskeleton’s admittance control parameter changes during  walking.  

Methods: Ten non-disabled individuals walked on a treadmill at  a self-selected speed, while wearing our bilateral robotic hip  exoskeleton. We used two equilibrium positions to define the  direction of assistance. We studied the influence of multiple  stiffness values in the admittance control on the participants’ step  width, step length, and electromyographic (EMG) activity of the  gluteus medius. Results: Step width were significantly modulated by the change  of stiffness in exoskeleton control, while step length did not show  significant changes. When the stiffness changed from zero to our  studied stiffness values, the participants’ step width started to  modulate immediately. Within 4 consecutive heel strikes right  after a stiffness change, the step width showed a significant change.  Interestingly, EMG activity of the gluteus medius did not change  significantly regardless the applied stiffness and powered  direction. 

Conclusion: Tuning of stiffness in admittance control of a hip  exoskeleton, acting in mediolateral direction, can be a viable way for controlling step width in normal walking. Unvaried gluteus  medius activity indicates that the increase in step width were  mainly caused by the assistive torque applied by the exoskeleton.  

Significance: Our study results pave a new way for future  design and control of wearable robotics in enhancing mediolateral  walking balance for various rehabilitation applications. 
Secret UAV Flight Paths Hiding in Digital Media with ElGamal Public Key Steganography
Authors: Wastupranata Leonard Matheus
Published: March 2023

UAV will need a travel route with specific location coordinates to complete the flight mission. However, many missions must be completed in secret, such as state duties, to ensure the safety of UAV flying from attacks by irresponsible parties. For this reason, a cryptographic mechanism for travel route data and steganography on a digital media is needed so that the security of data transmission is more guaranteed. The method used is ElGamal public key cryptography due to the good decryption speed and more difficult mathematical calculations thus improving data security. The Steganography method used  is Least Significant Bit (LSB) so that the quality of digital media after data insertion is not much different from the original. It was found that the entire experiment reached a value above 30 which showed excellent public key Steganography quality.
Indriya: Building a Secure and Transparent Organ Donation System with Hyperledger Fabric
Authors: Ghosh Satyajit , Dutta Mousumi
Published: March 2023

Recent technological advancements have led to the development of new methods for managing organ donation systems, which aim to overcome the limitations of traditional centralized systems. To achieve increased transparency, security, and efficiency in the organ donation process, blockchain technology is being proposed as a replacement for these centralized systems. However, most previous works on organ donation systems have focused on using Ethereum-based blockchain solutions, which offer limited control, a fixed set of consensus protocols, and no support for concurrent executions. In contrast, our work has utilized the Hyperledger Fabric framework to develop a network model of the organ donation system. We have designed and deployed a prototype system with smart contracts using Amazon Managed Blockchain Service. Additionally, we have built a client application that uses the Fabric SDK to interact with the network and perform various actions. To evaluate the performance of our system, we conducted extensive testing using the Hyperledger Caliper benchmarking tool. In our test bench, the system achieved a peak actual send rate of 389.1 transactions per second (TPS) for creating new records and 508.4 TPS for reading records. At a send rate of 800 TPS, the system took an average of 12.16 seconds to serve a request for creating a record and an average of 3.71 seconds to serve a request for reading a record. Future work is required to extend the functionalities of the system and identify potential endorsers and managers for this type of controlled blockchain network.
Divergence of Implants and Asymmetry of Fixed Prosthesis on Implants Case Report
Authors: González Jesús M. González-
Published: March 2023

This report presents the case of a 62-year-old man, who went to the dentist's office in May 2022 to rehabilitate the edentulous maxillary area. It was planned to place implants in positions 16, 14, 12, 22, 24, and 25, with a delayed technique in the placement of the fixed prosthesis. The implant 24 had a divergent position towards buccal. There was also an asymmetry in the prosthesis, since implants 24 and 25 were closer to each other, to avoid the proximity of the maxillary sinus on the left side, while piece 16 could be placed on the right side. The non-parallel placement of an implant is not a complication, but rather an unscheduled inconvenience. In many cases, it depends on the availability of bone to be able to place the implants in the positions programmed as ideal. To improve esthetics in screw channel 24, a making agent was applied. We have found it more reasonable to place tooth 16, even though it results in an asymmetric prosthesis. It is a tooth that is useful for the patient to chew and the asymmetry is minimal, concerning the whole of the prosthesis. Bone limitations in width and depth condition the position and angulation of the implants. The divergence and asymmetry of these implants also condition the way of making the fixed prosthesis on them. The choice between a cemented or screw-retained prosthesis is not essential, since in both cases a good oral, functional, and aesthetic restoration can be made.

Published: March 2023

A technique called phytoremediation makes use of a plant’s root system to draw contaminants, primarily heavy metals (zn, cr, and ni), from the surrounding rhizosphere. These are the end result of human actions such the use of pesticides, waste byproducts, cosmetics, and pharmaceuticals. This analysis focuses on soil contamination removal since prolonged exposure to heavy metals can cause respiratory illnesses, cardiovascular disorders, cancer of the liver, lungs, and kidneys, among other problems. In order to immobilise metals and change their harmful states into less toxic states, plants use a process called phytoremediation and tactics like phyto(rhizo) stabilisation. Chromium 6 is changed into chromium 3 through phytostabalization, a process in which plants are utilised to change a pollutant’s more hazardous form into a less hazardous volatile form that may be transported. Macrophytes, such as Arbidopsis thaliana and Cgara canescens, have been found to use phytofiltration and phytovolatization to remove radioactive and heavy metals. Indian mustard (Brassica juncea) and sun flower (Helianthus annus) are suitable plants for rhizofilteration, which is essential to prevent environmental and health problems. A heavy metal that is widely present in soil is cadmium. Cd can be removed physically in a number of ways, with membrane filtration and adsorption being the most often utilised techniques for doing so. Chemical (in which the addition of barium acetate caused coagulation) and biological (which uses microorganisms such bacteria, yeast species, fungal aspergillus, and green algea chlorel for the Bioremediation of Cd.) approaches are also employed for the removal of cadmium. In essence, phytoremediation uses the already-existing power of plant systems. This approach is more economical and environmentally benign than conventional approaches for cleaning up contaminated soil and ground water. Since drinking water contaminated with heavy metals is thought to be the primary cause of death in Pakistan, getting rid of these pollutants is our top priority.

Authors: Balwan Wahied Khawar , Saba Neelam , Kour Sachdeep
Published: March 2023

Mycotoxins are secondary metabolites produced by fungi and are capable of causing various diseases in humans and animals. They are naturally occurring chemical substances and are chemically stable which is why they pose a great threat to public health. Accumulation of mycotoxins in the food chain can cause hazardous effects in human. The gut microbiota has a bidirectional relationship with mycotoxin, being the leading cause of the development of mycotoxicosis. These fungal toxins exhibit a number of adverse health effects in animals, even at very low concentrations, and have been associated to cases of acute and chronic poisoning of humans and farm animals since historical times. Preventive measure for controlling contamination should be adopted both before and after harvest. Mycotoxin occurrence cannot be completely avoided, but a number of measures aiming at minimizing mycotoxin levels and mycotoxin exposure can be implemented at multiple points in the food and feed chains.

Introduction: Intertrochanteric fractures are a type of extracapsular fractures of the proximal femur occurring between the greater and lesser trochanter. They are frequently seen in the elderly because their incidence is higher as life expectancy increases.
Objective: to describe the current information related to epidemiology, anatomy, presentation, classification, evaluation and management of intertrochanteric fractures.
Methodology: a total of 35 articles were analyzed in this review, including review and original articles, as well as clinical cases, of which 27 bibliographies were used because the other articles were not relevant to this study. The sources of information were PubMed, Google Scholar and Cochrane; the terms used to search for information in Spanish, Portuguese and English were: transtrochanteric, intertrochanteric, femur, fracture, fratura.
Results: Intertrochanteric fractures have a bimodal presentation. They have a female to male ratio ranging from 2:1 to 8:1, possibly due to changes in bone metabolism after menopause. They are frequently seen in the elderly because their incidence is higher as life expectancy increases. Plain radiographs are still the initial choice to complement the diagnosis in this type of fractures. It is preferable to take anteroposterior (AP), AP and lateral cross pelvis projections of the affected hip and full body radiographs of the affected femur. Surgical treatment is preferred over conservative treatment except in cases that contraindicate surgery or anesthesia.
Conclusions: Intertrochanteric fractures are a type of extracapsular fractures of the proximal femur occurring between the greater and lesser trochanter. Femur fractures have several classifications, recently the classification of intertrochanteric fractures is based on the stability of this area. It is of vital importance to evaluate whether it is an open or closed fracture, in addition to assessing the neurovascular status. The surgical treatment has the mission of providing a stable internal fixation that allows early mobilization and full weight bearing. There are several tools and techniques to provide surgical treatment, however, in our current reality, intramedullary nails are the most used devices in the treatment of intertrochanteric fractures. Regardless of the therapeutic alternative chosen, the mortality risk is 20% to 30% in the first year after the fracture, with males being more affected than females.
KEY WORDS: transtrochanteric, intertrochanteric, femur, fracture.
MULTI-SCALE ATTENTION BASED U-NET MODEL FOR LIVER TUMOR SEGMENTATION
Authors: J. Jenisha  , A. Joel Dickson
Published: March 2023

It is essential to automatically evaluate the position and size of the liver tumour for radiologists, diagnosis, and the clinical process. Many U-Net-based variants have been suggested in recent years to enhance the segmentation results for medical image segmentation, but they are unable to describe the global spatial and channel relationships among lesion regions. To overcome this issues, we proposed a novel network called Multi-scale Attention UNet (MA-UNet) to address this problem by adding a self-attention mechanism into our approach to adaptively combine local features with their global dependencies. The attention mechanism of the MA-UNet allows it to capture complex contextual dependencies. Position-wise Attention Block and Multi-scale Fusion Attention Block are the two blocks that we have developed. The feature interdependencies in spatial dimensions, which represent the spatial dependencies between pixels in a global view, are modelled using the Position-wise Attention Block. A multi-scale semantic feature fusion attention block is also used to capture the channel dependencies between any feature map. On the MICCAI 2017 LiTS Competition dataset, we assess our methodology. Compared to other cutting-edge methods, the suggested way performs better. The Dice and VOE values of liver tumors segmentation are 0.749 ± 0.08 and 0.21 ± 0.06 respectively.

Contexte : La rétroaction écrite est primordiale dans l’enseignement aux résidents, mais les précepteurs ne sont pas toujours bien outillés pour offrir une rétroaction pertinente. Cette étude visait à évaluer l’efficacité de formations multiépisodiques et l’utilisation d’un guide critérié pour les rétroactions écrites des précepteurs en médecine familiale d’un centre hospitalier académique francophone.

Méthode : Vingt-trois (23) précepteurs ont participé aux formations et ont utilisé le guide critérié pour les guider lors de l’évaluation écrite dans une fiche évaluative nommée « feuille de route ». Le contenu de ces feuilles de route a été analysé selon la complétion, le taux de rétroactions spécifiques et le taux de rétroactions par rôle CanMEDS-MF avant et après les formations sur une période de 3 mois.  

Résultats : Selon l’analyse des feuilles de route (n=70 prétest ; n=138 posttest), une augmentation du pourcentage de complétion (50% vs 92%, z=2.97, p=0.0030) et de rétroactions spécifiques (59% vs 92%, z=2.47, p=0.0137) fut notée. Il n’y avait aucune augmentation significative quant aux rétroactions par rôle CanMEDS-MF.  

Conclusions : L’élaboration de formations multiépisodiques et d’un guide critérié, créés selon le référentiel CanMEDS-MF, suggère une amélioration de rétroactions écrites complètes et spécifiques en éducation de la médecine familiale.

Background: Surveys are being increasingly used to gather feedback and study data in healthcare professions. However, it may be challenging to achieve high response rates in surveys administered to healthcare professionals. The aim of this paper is to report six strategies that contributed to a high response rate on the Independent Student Analysis at the University of Toronto (U of T), which can be applied to other surveys to achieve strong response rates amongst healthcare professionals.
Methods: In 2019, as part of accreditation for the U of T MD Program, we conducted the Independent Student Analysis, a student-led survey examining a medical student’s experience. We review and critically evaluate the factors that contributed to a robust response rate amongst one of the largest cohorts of medical students in Canada.
Results: Among 1080 students in the MD program, we achieved an unprecedented response rate of 87.2%. Six factors were identified that most contributed to our high response rate, including: faculty support, student representation, eliciting participant feedback, creating protected time for completion, offering incentives, and generating awareness.
Conclusions: Eliciting high survey response rates from medical learners can be challenging. However, with careful consideration of learner feedback and effective employment of the strategies discussed in this paper, medical school faculty may better engage students in survey completion, achieving higher response rates and gathering richer insight, which can be used to more effectively enact meaningful change amongst healthcare professionals.
Das Hochschulförderungs- und -koordinationsgesetz und seine Bedeutung für die Steuerung Pädagogischer Hochschulen in der Schweiz
Authors: Eckert Nancy
Published: March 2023

Pädagogische Hochschulen wurden bis zur Einführung des Hochschulförderungs- und -koordinationsgesetzes im Jahr 2015 durch die Kantone (Erlass Hochschulrecht) sowie die Schweizerische Konferenz der kantonalen Erziehungsdirektoren (Erlass Anerkennungsrecht) gesteuert. Im Zuge dieser jüngsten Gesetzesänderung haben sich die Kompetenzbereiche der involvierten Steuerungsakteurinnen und Steuerungsakteure wie auch die Steuerungsmechanismen für diesen Hochschultyp verändert. Im vorliegenden Beitrag soll der Frage nachgegangen werden, inwiefern sich durch das Bundesgesetz die Steuerung Pädagogischer Hochschulen gewandelt hat und welche Konsequenzen sich daraus für die Institutionen der Lehrerinnen- und Lehrerbildung ergeben.
Praxisrelevanz von Forschung als gemeinsame Aufgabe von Wissenschaft und Praxis: Entwurf eines Angebots-Nutzungs-Modells
Authors: Brühwiler Christian , Leutwyler Bruno
Published: March 2023

Der Anspruch, dass Forschung auch «in der Praxis» oder «für die Praxis» einen Mehrwert bieten soll, materialisiert sich oft in der Forderung nach «Praxisrelevanz». Der vorliegende Beitrag diskutiert offene Fragen, die mit der gängigen Forderung nach Praxisrelevanz einhergehen, und identifiziert Voraussetzungen dafür, dass Forschungsergebnisse relevant werden können. In Anlehnung an Angebots-Nutzungs-Modelle der Unterrichtsforschung wird ein Angebots-Nutzungs-Modell für Praxisrelevanz von Forschung skizziert. Das Modell macht deutlich, dass das Erzeugen von Praxisrelevanz nicht einseitig eingefordert werden kann, sondern nur in gemeinsamer Verantwortung von Wissenschaft und Praxis gelingen kann. Der Beitrag schließt mit Überlegungen zu den Implikationen eines solchen Modells für die Lehrerinnen- und Lehrerbildung.
Bildung für eine Nachhaltige Entwicklung und Lehrerinnen- und Lehrerbildung – eine Beziehung mit Potenzial

Published: March 2023

Bildung für eine Nachhaltige Entwicklung (BNE) hat für die Lehrerinnen- und Lehrerbildung auf wissenschaftlicher und bildungspolitischer Ebene an Bedeutung gewonnen. Im Rahmen der «Beiträge zur Lehrerinnen- und Lehrerbildung» (BzL) ist das Thema indes kaum abgebildet – es erschienen nur wenige Beiträge in den vergangenen 25 Jahren. Es lässt sich daher feststellen, dass BNE im schweizerischen Professionalisierungsdiskurs noch kaum wahrgenommen wird, obwohl das Thema in der Lehrerinnen- und Lehrerbildung angekommen ist und in der professionsspezifischen Auseinandersetzung durchaus ein Potenzial vorliegt, auf Herausforderungen zu reagieren, mit denen die Lehrerinnen- und Lehrerbildung konfrontiert ist: die zunehmende fachliche Fragmentierung sowie das Verhältnis von Unterrichtspraxis und wissenschaftlicher Praxis.
SYNERGETIC EFFECT OF STRENGTHENING POLYMER NANOCOMPOSITES

According to the cluster model of glassy polymers, in the amorphous state they are natural nanocomposites of two components of a loosely packed matrix and nanoclusters immersed in it, respectively playing the role of a matrix and filler in a natural composite. In this interpretation of the polymer, an important role is played by the dimensional effect of nanoclusters, identical to the specified effect of a nanofiller in an artificial nanocomposite, namely, a decrease in the size of both nanoclusters and dispersed particles leads to a sharp increase in the degree of amplification (modulus of elasticity) of the nanocomposite.
In this paper, using parallel and sequential microcomposite models, upper and lower fractal estimates for the elastic modulus of the matrix are obtained and the synergistic effect of strengthening the elastic modulus of the nanocomposite as a whole as a superposition of the amplification effects from inorganic filler and from nanoclusters playing the role of filler of the loosely packed matrix is quantified.
The object of research in this work is a packer - a device designed to disconnect two zones of the borehole and isolate the internal space of the production column from the impact of the borehole environment. The tightness of the packages is achieved thanks to sealing elements (SE), for the manufacture of which a composite with the composition is used: a mixture of synthetic butadiene nitrile and hydrogenated butadiene nitrile rubber (BNC + HBNC), vulcanizer, stabilizer, technological additives and copper nanoparticles.
For the class of polymers under consideration, a rule has been developed for choosing the most preferred model from the above two micromechanical models at a given temperature.

IRRADIATION OF CARBON DIOXIDE WITH A VACUUM UV SOURCE AND OBTAINING OF STRATOSPHERIC OZONE
Authors: Elshan Aliyev Marat Huseynov , Tarana Aghadiyeva Hilal Tahirli
Published: March 2023

It has been known for more than 100 years that carbon dioxide absorbs photons in the ultraviolet and infrared ranges of radiation, creating a greenhouse effect. However, so far no one has answered the question: what is a photon?
It is known that a photon has corpuscular and wave properties, has a certain pressure. An interesting experiment was carried out when a photon was dissected using Wilson chamber and it left traces of the opposite sign. The correct conclusion was made that one trace in the Wilson chamber was left by an electron, and the other - by a positron.
There were other experiments, for example: birefringence of light in quartz crystals, Icelandic spar, etc., but there were no correct conclusions made about what a photon is.
A photon is an electric dipole, consisting of an electron and a positron charges, without a spin charge-conjugate formation, which has a dipole magnetic field.
Carbon dioxide, absorbing photons with a mass of 18.210-31 kg, being structured in the core, turns into triatomic oxygen, that is, into stratospheric ozone.
A photon absorbs only a carbon atom that has an excess of spins. Photons absorbed by carbon dioxide (electric dipoles) having a magnetic field interact with the magnetic force lines of the dipole magnetic field of the Earth, and as a result of such interaction, triatomic oxygen-ozone moves into the stratosphere. Stratospheric ozone is not explosive in all aggregate states and at high pressures. In the atmosphere, it enters into a nuclear interaction with neutrons emanating from the sources of future earthquakes, forming water. So, naturally, the ozone layer of the Earth is depleted, replenishing the hydrosphere.
Irradiation of CO2 and production of stratospheric ozone is a solution to the problem of climate warming. Stratospheric ozone can be widely used in the defense industry. An airship filled with stratospheric ozone will be much more efficient than airships filled with hydrogen or helium.
The production of stratospheric ozone from carbon dioxide is a fundamental discovery in the field of photonuclear physics.
Key words: electric dipole, photon, carbon dioxide, stratospheric ozone, photonuclear reaction.

The purpose of the work: modernization of the valve, in order to increase reliability, wear resistance, increase the pump flow and reduce the load on the rod string. As well as improved durability. Object of work: Rod pump valve.
Realization of the goal is achieved by performing the following tasks:
1. Overview of known designs of the valve assembly of a sucker rod pump;
2. Identification of a number of causes of valve failure, as well as its causes of wear;
3. Calculation of the main parameters of the pump;
4. Overview of the design of a sucker rod pump, to understand the problem;
5. Development of measures for the maintenance and repair of the pump.
In the course of the WRC, a review and analysis of information on the designs of the valve assembly of a borehole rod pump was carried out. The problem of its wear has been studied. The problem of valve design is formulated and solved.
At the moment, sucker rod pumps (SRP) and electric submersible pumps (ESPs) are used. Since the ESP has much higher production capabilities compared to the rod, the main volume of oil in the country is produced using ESP units.
In view of the fact that the simplicity of the design of the SRPU is the most maintainable during practical operation, it is precisely such installations that are used at the moment. And also the positive aspects of the SRPU are the convenience of its adjustment, the small effect on the operation of the SRPU of the physical and chemical properties of the pumped liquid, the relatively high efficiency and the possibility of operating wells of small diameters, compared with other installations and methods of operation.
However, SRPU oil production is based on relatively old oil production technology and techniques, especially for downhole and downhole equipment and technological operations carried out using this equipment.
The development, manufacture and testing of new equipment is becoming especially relevant.
The purpose of my project is to increase the filling factor of a sucker rod pump, as well as to increase the reliability of its operation after repairs. An increase in the filling ratio of the SRP is achieved by upgrading the valve assembly, and an increase in reliability.
