Label-free 3D tracking of biological micro-objects using RGB pinholes
Authors: Kim Doyeop , Matsuzaki Takahisa , Yoshikawa Hiroshi Y. , Kawamura Ryuzo
Published: April 2024

Defocusing digital particle image velocimetry is a method developed within the field of fluidics to measure the velocities of particles within a volume through image analysis. For three-dimensional (3D) tracking, approaches utilizing defocusing techniques have been proposed to enable depthwise positional measurements. Recently, there have been suggestions to simplify this approach by employing a triple pinhole mask and to further enhance it with color filters that allow distinguish particles, even under dense conditions. This paper presents an attempt to apply the defocusing method using a triple pinhole mask with red, green, and blue (RGB) color-coding filters, demonstrating the successful label-free 3D tracking of biological micro-objects at multiple positions within a volume. The application of this method in fluidics and its potential for biological analysis are highlighted through successful examples of 3D tracking involving micro-particles influenced by motor proteins, dividing cells, and swimming microorganisms.

Authors: Komatsubara Yuki , Ishibe Takafumi , Miyato Yuji , Nakamura Yoshiaki
Published: April 2024

Thermoelectric nanocomposite materials are attracting much attention due to their high thermoelectric performance brought by effectively combining thermoelectric properties of the matrix and introduced nanostructures. However, understanding the mechanism of Seebeck coefficient enhancement brought in nanocomposite materials is difficult because there are no measurement methods of thermoelectromotive force V
TE on the nanoscale. In this study, we demonstrate that the controlled temperature gradient Kelvin force microscopy (T-KFM) measurement we developed in 2021 can be applied to nanocomposite films. We observe temperature difference ΔT-induced vacuum level V
vac variation, which is related to V
TE, in PEDOT:PSS/Si nanowire nanocomposite films using T-KFM. The large ΔT-induced V
vac variation at the tops of Si nanowires is generated, which is mainly explained by the larger Seebeck coefficient value of the Si nanowire. This application of T-KFM to the nanocomposites highlights that T-KFM will be a powerful tool for the development of nanocomposite materials with controlled thermoelectric properties on the nanoscale.

Published: April 2024

The Credit Card Transaction System, is developed using the XAMPP server-a combination of Apache, MySQL, Perl, and PHP-is a dependable and secure financial software solution. For seamless credit card transactions, this system places a strong emphasis on functionality and security. The Apache web server ensures user accessibility by enabling the online application to be hosted on a stable platform. MySQL, a relational database management system, securely stores and manages sensitive data, protecting its security and integrity. The program integrates PHP and Perl scripts to process payments, which is one of its primary features. PHP is a programming language on the server side that handles the dynamic aspects of the website, ensuring efficient data exchange between the database and user interface. Perl scripts offer a range of server-side functions that enhance system functionality, making transaction processing more comprehensive and responsive. The NodeMCU, acting as the backend system's central processing unit, manages communication with the RFID Module RC522. The RFID Module RC522, which enables customers to initiate with their respective RFID cards resembles a credit card in this prototype. Each RFID card has a unique identification number that paves the way to diverse customer access and usage. This reliable hardware configuration makes very little effort required to process the payments. The main objective of developing this prototype is to enhance the safety and security environment of the existing credit card system by adding personal questions that have to be answered by the payment maker to complete the transaction. It is almost impossible to crack the personal questions stage with advanced algorithms, mathematical techniques etc, because it is only known to the authorized user of the card. Although the frauds and thefts involving credit cards occur only in small percentages around 1%-3%, the volume of payments involved is huge when compared to credit cards. Thus, resulting in a large sum of money that has been misused by the fraudsters. Hence to protect this, the proposed system has suggested a novel method for the implementation of the small and safe system to proceed with payments. This little and effective feature keeps away hackers from accessing others' credit cards and prevents speculation.

Novedad y dificultades del concepto Kantiano de Lógica Formal
Authors: Vázquez Lobeiras María Jesús
Published: April 2024

El presente trabajo contiene una presentación de la noción kantiana de lógica formal o general, considerando que se trata de un logro del pensador de Königsberg muy relevante pero un tanto velado y que, por diversas razones, no ha obtenido suficiente reconocimiento. Se analizan tres núcleos de dificultades que emanan de los propios textos de Kant: a) el problema de las fuentes, b) la compleja interrelación entre tres enfoques diferentes, que aquí llamamos logicista, psicologista y funcional, y c) el problema de la formulación de la noción de lógica formal en el mismo proceso reflexivo que da lugar a la lógica trascendental. La discusión de la caracterización de la lógica como formal y su denominación como general ofrece algunas claves de interpretación. Y, por último, se señala la particularidad de la lógica fomal o general como única ciencia que se sustrae al giro copernicano.
COMPLICATIONS OF COCHLEAR IMPLANT
SURGERY: A DETAILED STUDY
Authors: Maheshwari Sumit
Published: April 2024

INTRODUCTION
Cochlear implantation is nowadays the most
important means to restore hearing in patients
with severe to profound sensorineural hearing
loss who are not managed by conventional
hearing amplification methods. The cochlear
implant helps patients in better understanding
and improvement in auditory abilities, speech,
and linguistic development. The best results are
obtained by doing the implantation at the earliest
possible age. As with any other surgical
procedure, cochlear implantation also has risks
and complications associated with it. It can be
minor or major complications. In our study, we
have discussed in detail the challenges and
complications of cochlear implant surgery.
MATERIAL AND METHODS
This is a retrospective study including 500
patients who were evaluated and operated for
cochlear implants at MEHROTRA ENT HOSPITAL,
Kanpur, India. All patients were investigated by
audiological tests such as aided audiometry, ABR,
and otoacoustic emission and found to have
severe to profound bilateral SNHL. All patients
were radiologically evaluated with CT and MRI.
Aretrospective review of the patient's data was
done including the patient's characteristics,
surgery, outcome, and complications.
RESULTS
A total of 500 patients were included in our
retrospective study out of which 337 were males
and 163 were females. All the surgeries were
carried out by the same group of surgeons using
the standard technique of post-auricular incision
and posterior tympanotomy. Patients have been
followed up regularly and a close watch was kept
on the vital signs, lightreflex, pupil size,
consciousness, and wound healing. After surgery,
patients were kept in the hospital for 2–3 days.
Parenteral antibiotics and the compressive
mastoid dressing were given, and the patient was
discharged with oral antibiotics. We followed up
with the patients regularly and managed the
complications experienced by them.
CONCLUSION
Cochlear implantation remains a safe and
effective surgical procedure for profound
sensorineural hearing loss. We have a moderate
rate of minor complications and a minimal rate of
major complications in relation to other studies.
The majority of minor and major complications
can be avoided with adequate surgical
techniques and can be managed conservatively.

COMMERCIAL PROPOSAL TO AN AGRICULTURAL MANUFACTURER REGARDING THE PRODUCTION OF BIODIESEL FUEL WITH THE CALCULATION OF ECONOMIC EFFICIENCY
Authors: RYABOSHAPKA Vadim
Published: April 2024

The market of petroleum products in Ukraine, in particular diesel fuel, over the past three years has been analysed. A decrease in the use of the main types of fuel in 2022 compared to 2021 has been determined across the country due to shortages and price increases due to market reorientation in wartime conditions. The year 2023 showed an increase in the use of petroleum products due to the stabilization of supply and demand, although these volumes are still lower than in 2021. The amount of fuel used for growing of the main agricultural crops in Ukraine using various technologies is given, taking into account the productivity indicators and the area of sowing. A specific assessment of the component of production costs for fuel was carried out, on the basis of which, taking into account the price of diesel fuel and the area of arable land in Ukraine, the market shares of diesel fuel accounted for by agricultural production was estimated. The forecasts of scientists regarding the need for diesel fuel on the scale of the country, which will grow every year, increasing the demand for biodiesel fuel, are considered. A reasoned position is presented regarding the relevance of biodiesel production in Ukraine for the needs of agriculture. The measures and regulations that stimulate the production of biodiesel fuel in the countries of the European Union and the state of state support for it in our country, as well as the oil products market for 2023 from the point of view of sales volumes and fuel prices, are analysed. It is proposed to start the production of biodiesel fuel on the basis of agricultural farms or processing enterprises on the order of producers of agricultural products from their raw materials. A methodology for assessing the economic efficiency of biodiesel production has been developed, based on the price of raw materials, which involves primary and secondary processing (raw material - rapeseed), or only secondary processing (raw material – rapeseed oil). During the primary and secondary processing, the added value obtained from the by-products is taken into account, which reduces the cost price of the produced biofuel. This methodology also takes into account such a factor of increasing the cost of production of biodiesel fuel as an excise tax. When evaluating the economic efficiency by comparing it with the market value of standard diesel fuel, the concept of energy coefficient, which takes into account the ratio of the lower heat of combustion of two types of fuel, was introduced. This scientific work presents the results of the initiative research work 0122U002187.

Published: April 2024

Introduction: 225Ac-PSMA is a promising drug for radioligand therapy (RLT) in patients with metastatic castration-resistant prostate cancer (mCRPC). Despite the large number of studies in this area, the optimal therapeutic activity of the drug is a debatable issue. The purpose of this study is to evaluate the safety of a single dose of 225Ac-PSMA at a fixed dosage (regardless of patient weight) of 6, 9 and 12 MBq.

Material and methods: The study included 9 patients, 3 in each group, with mCRPC progressing against the background of standard treatment (from 1 to 6 lines of mCRPC therapy in history). The observation period was 5 weeks, instrumental, laboratory and clinical indicators were used to assess safety. 225As-PSMA was manufactured directly in the clinic in accordance with the order of the Ministry of Health of Russia 1218n dated 11/12/2020.

Results: During the observation period, one patient from the group with the lowest administered activity had a serious adverse event (hospitalization due to pneumonia). When discussing this case, it was concluded that there was no connection with the drug, since pneumonia in this patient was not accompanied by leukopenia or neutropenia. All patients experienced dry mouth. In patients who received 9 and 12 MBq a decrease in the salivary gland function was recorded by scintigraphy. In two patients, severe weakness was revealed, in one of them the weakness could be associated with pneumonia, in the other patient, the weakness was most likely caused by the therapy. No cases of nephrotoxicity were recorded. Hematological toxicity was temporary reversible; no additional treatment was required in any of the cases. The most common adverse event: leukopenia, neutropenia (78 % of patients), grade III leukopenia was observed in two (22 %) patients, grade III neutropenia in one (11 %) patient.

Conclusions: A single administration of 225Ac-PSMA in the studied range of activities was safe, dose-limiting toxicity was not achieved.

Authors: Arablinskii A. V. , Myasnyankina O. P. , Sedova A. A. , Onischenko M. P.
Published: April 2024

Purpose: To report a clinical case demonstrating difficulties of diagnosis and successful surgical treatment of myomatous type of angiomyolipoma of the liver without simultaneous damage to the kidneys.

Material and methods: A female patient, 49 years old, was admitted to the hospital in August 2023, had no specific complaints, an abdominal ultrasound revealed extraperitoneal extraorgan mass in the epigastrium and mesogastrium and masses in the right lobe of liver, most likely hemangioma. The contrast-enhanced MSCT was performed on admission. Patient was rehospitalized for a surgery in September. During the operation the tumor was removed and sent for histological examination, a further immunohistochemical study was also carried out.

Results: According to the results of MSCT in S3, S4, S5 of the liver oval-shaped mass (198×104×177 mm) with heterogeneous density and solid, cystic and fat features was found. Three hypovascular hypodense inclusions sizes up to 11 mm was also identified in S7/8. There was no pathologic formation in the kidneys. The liver tumor was surgically removed, the resected material was directed to a scheduled histological examination. To confirm the diagnosis an IHC analysis was also done and it revealed the expression of melanocytic (HBM-45) and smooth muscle (SMA) markers.

Discussion: In this case we encountered very sparsely described in the world literature localization of angiomyolipoma — isolated hepatic one (without kidney damage). Like other authors we encountered the similarity of muomatous tumor type to the HCC and adenoma of the liver due to the characteristic features of visualization: hypervascularity, early contrast enhancement into an arterial phase and reduced density relative to the preserved parenchyma of the liver into a delayed phase of contrast.

Conclusion: This case demonstrates the difficulty of diagnosing the myomatous type of AML simulating the HCC. As one of the most informative methods of diagnosis, we single out MSCT, which allowed us to think about the possibility of a benign nature of the tumor. In our case the main features excluding HCC were the absence of rapid “washout” of contrast drug, the presence of lipomatous areas and no accumulation of contrast agent by the capsule.

Carbon fiber-reinforced polymer composites are widely used materials in the aircraft industry, automotive sector, marine applications, civil engineering, and daily consumer goods, due to their superior mechanical properties at a relatively low density compared to metallic materials. The studied composites are composed of an epoxy resin matrix in which three layers of carbon fiber fabric are embedded, oriented at 0 and 90 degrees. Carbon fiber-reinforced polymer composites were manufactured using the Vacuum Assisted Resin Transfer Molding technique. The tensile failure mechanism in carbon fiber-reinforced polymer composites is an extremely complex phenomenon influenced by numerous factors. This study aims to evaluate the mechanical behavior of carbon fiber-reinforced composites through tensile testing and to compare experimentally obtained results with those calculated using the mixture rule. Additionally, the behavior of the materials under tensile stress was analyzed using the digital image correlation method. Estimating mechanical properties based on the mixture rule is a common practice in the design phase of polymer composites. This study s novelty and originality lie in its anticipation of the tensile strength and modulus of elasticity of the studied composites. This anticipation was achieved using a virtual instrument developed in the LabVIEW graphical programming environment. The experimentally obtained results for the tensile characteristics of the studied materials are suitable for this type of composite. These results were compared with estimates derived from the mixture rule, and the absolute error was determined.

Published: April 2024

This research paper presents comprehensive insight into the testing of a 1 KW sun tracking photovoltaic (PV) performance. The study uses a state-of-the-art real-time string monitoring system to allow this analysis while covering an extensive variety of atmospheric conditions. The design of the 1 KW solar tracker system incorporates a tracking sensor circuit, motor driver circuit, string monitoring system, and solar tracker control circuit. Solar tracking systems boost energy generation by adjusting the angle of PV panels to optimum sunlight exposure. The effectiveness of such devices can, however, be severely impacted by atmospheric changes. In a photovoltaic (PV) facility, we have successfully developed and placed into use a real-time system for monitoring certain strings. The system collected data on key parameters such as current, voltage, and temperature, providing insights into the health and efficiency of each string. Our study encompassed various atmospheric conditions, including clear skies, cloudy days, and fluctuating solar radiation. A DAQ system developed communicate with observations such as the voltage and current of photovoltaic arrays and the voltage and current of DC motors. When comparing the dual-axis tracking system to the static PV system, a maximum of 48% more electricity can be extracted. Both days with clear skies and days with clouds provide satisfactory results. The supply for the tracker control circuit comes from PV cells. Therefore, there is no need for any auxiliary supply, such as a battery.
A Novel Approach for Islanding Detection in Distributed Wind Energy Generators within Renewable Energy-Integrated Smart Grid using the 3-Parameter Sine Fit Algorithm
Authors: Misra Sudheeksha , Jha Bhola , Mishra V.M
Published: April 2024

This paper introduces a novel islanding detection method employing the 3 Parameter Sine Fit (3PSF) algorithm, which accurately estimates the angle between voltage and current at Distributed Generators (DGs). The method improves islanding identification in a test system consisting three Wind Energy Generators (WEGs) and an Emergency Diesel Engine Generator (EDEG). To demonstrate the efficacy of suggested novel strategy, the assessment is done under variety of situations such as islanding, load shedding and distribution line loss. Furthermore, a new mathematical model is developed for load shedding and this mathematical model is validated under wide range load shedding variations. This is validated that the 3PSF technique is a potential option for accurate islanding identification. Its superior sensitivity and resilience over ROCOF are highlighted by the results, which are confirmed by MATLAB-Simulink simulations.

Published: April 2024

Photovoltaic (PV) systems have emerged as a promising energy resource that caters to the future needs of society, owing to their renewable, inexhaustible, and cost-free nature. The output power of these systems relies on solar cell radiation and temperature. To mitigate the dependence on atmospheric conditions and enhance power tracking, a conventional approach has been improved by integrating various methods. The Maximum Power Point Tracking (MPPT) algorithm is employed to optimize power extraction from PV systems. To overcome limitations such as steady-state voltage oscillations and improve transient response, two traditional MPPT methods, namely Perturb and Observe (P&O) and Fuzzy Logic Controller (FLC), have been modified. This research work aims to simulate and validate the fuzzy step size of the proposed modified P&O and FLC techniques within the MPPT algorithm using Matlab/Simulink™ for efficient power tracking in PV systems.

Published: April 2024

The article discusses certain aspects of the implementation of the principle of accessibility of justice in the context of the widespread introduction of informatization and digitalization. Based on the study of the legislative framework, the doctrine of procedural law, the law enforcement activities of the Constitutional Court of the Russian Federation and the European Court of Human Rights, the author problem of the impact of digitalization on ensuring accessibility of justice and the right to judicial protection is being investigated. The problems of using information technologies in the course of the administration of justice are highlighted, as well as the issues arising in connection with their use by the parties and the court. The debatable aspects of the use of information technologies in the framework of certain types of legal proceedings are touched upon, in particular, in the context of the practical implementation of the adopted procedural novels, ensuring the equality of participants in legal proceedings, and resorting to simplified procedures for considering and resolving cases. It is noted that the use of digital technologies solely for the purpose of procedural economy and solving organizational issues of courts is unacceptable, as well as their mandatory implementation if it does not ensure the equality of participants in legal proceedings, the real effect of the constitutional right to judicial protection, and also goes against the principle of access to justice. In the context of limited legal regulation, the material and technical base of domestic courts, the author comes to the conclusion that it is necessary to preserve the traditional form of administration of justice, paperwork, as well as a deep and comprehensive analysis of the use of implemented technologies through the prism of accessibility of justice and the expansion of normative and real guarantees for the exercise of procedural rights.

The article shows that despite the steady growth in demand for daily rental of residential premises, the use of apartments for designated purposes raises many questions in society, legal doctrine and judicial practice, among which is the issue of the ratio of short-term rentals and the provision of hotel services, as well as the need to ensure a balance of interests between owners of residential premises leased daily hiring, and persons permanently residing in an apartment building (neighbors) and thus implement the principle of solidarity, and protection of the right to housing at the same time as the economic efficiency of the use of living space. The authors proceed from the fact that at the moment the relations developing in connection with the daily rental of residential premises do not have a clear legal regulation, which entails the need in each specific situation to raise the question of the legal qualification of the concluded contract, and often requires judicial interpretation. Analyzing judicial practice, the draft law with the proposed amendments, as well as the doctrine, the authors conclude that when qualifying a contract mediating the transfer of an apartment for daily rent, the differentiation should primarily occur based on the intention to create a sufficiently stable connection with the place of residence. Some ways are proposed to ensure a balance between the interests of the owners of apartments for rent, on the one hand, and neighbors, on the other hand. In conclusion, it is summed up that this problem requires a thoughtful and adequate response from the legislator, and the hope is expressed that in the new law and the judicial practice that develops on its basis, it will be possible to ensure a balance of interests and implement the principle of solidarity.
