Authors: Shakirova E. V. , Semykin M. V. 
Published: July 2023

It is well-known that large amounts of data are collected and processed during the operation of electric submersible pumps. To optimize the work of mining control center operators, it is recommended to use an automated emergency prevention system. In this way, operators will be able to receive timely information about possible equipment failures, which in its turn will increase the service life of the equipment and reduce operating costs for repairs. The purpose of the present research is to develop a model predicting submersible pumping equipment failures using the method of artificial intelligence. To identify the most accurate model, the paper compares the following forecasting methods: the nearest neighbour method and the linear classifier building method. The presented correlation was created on the basis of 30 parameters obtained from 272 wells of the Eastern Siberia field. Being used, it enabled error-free prediction of failures and complications in pumping equipment operation depending on the gas factor and frequency. Thus, the developed model can be used by oil and gas enterprises to predict failures and accidents in the operation of submersible pumping equipment. The conducted study shows that the prediction accuracy of the required parameter in the developed artificial intelligence model exceeds the results of conventional statistical methods. The model also can be useful for future optimization of processes when field planning and developing. Artificial intelligence is the best prediction method of submersible pumping equipment failures, due to its high speed and accuracy, cognitive technologies are widely used in big data processing.

Retinoblastoma (RB) is one of the most common malignant neoplasms of the visual organ in children, with an established genetic factor in the development of the disease. The detection of mutations in the RB1 gene has been successfully carried out for many years, however, the development of technologies for DNA diagnostics of RB allows us to consider this disease not only as an independent tumor, but also as one of the manifestations of more complicated genetic syndromes involving a complex of genes. The correct genetic diagnosis is important to understand the prognosis of the health of a patient with RB and recommendations for his further observation, as well as a correct assessment of the risks of having children with the same pathology in the family.Currently available methods of DNA diagnostics of the RB1 gene are new generation sequencing (NGS) and multiplex amplification of ligated probes (MLPA). However, in some cases, additional diagnostics may be required – a karyotype study or chromosomal micromatrix analysis (CMA). In this article we present a molecular genetic study of children with uni- and bilateral RB with an extended deletion at the RB1 gene locus. The aim of the study was determining of possible indications for the appointment of extended DNA diagnostics.

Synthesis and Characterization of Carbon Nano Sphere-doped Gd: Alpha
Sb2O4 Nanostructure for High-Performance Energy Storage Applications
Authors: Adimule Vinayak , Lakshminarayana Parashuram , Sharma Kalpana , Manhas Nidhi , Nabgan Walid 
Published: July 2023

Background:
To enhance the super capacitive properties of nanocomposites, the effective
method is to combine carbon nanospheres with mesoporous structures with Gd3+:α-Sb2O4
inorganic nanocomposites (NC) to form hybrid electrodes. An as-prepared hybrid electrode material
possesses increased energy density, high rate of reversibility and cyclic stability when
incorporated in electrochemical cyclic voltammetric studies.

Methods:
In the present investigation, various wt % of C-nanospheres (Cx) (5 %, 10% and 20%)
were decorated over Gd3+: α-Sb2O4 nanocomposites and were synthesized by coprecipitation
method. XRD, SEM, EDX, UV-visible, and XPS are only a few of the analytical techniques
used to describe the as-prepared hybrid nanocomposites. Electrochemical cyclic voltammetry
was carried out in a 6 M KOH solution, three-electrode system.

Results:
The crystal structure and morphology of Cx: Gd3+@ α-Sb2O4 NC showed a mixed hexagonal
phase and agglomerated tiny irregularly shaped morphology that appeared as the Cx concentration
increased. Redshift in optical absorption peak appeared (near UV-edge), and the optical
band gap (Eg) value increased from 3.53 eV to 3.65 eV. The electrochemical supercapacitor
showed the highest specific capacitance of 989 F/g at the current density of 1 A/g for
C20%:Gd3+@α-Sb2O4 NC compared with Cx:Gd3+@α-Sb2O4 (x = 5% and 10%) and undoped
Gd3+:α-Sb2O4 NC. The change in phase angle and Rs value of 1.98 was attributed to the ideal
supercapacitor properties. The cyclic stability after 5000 cycles with 79.71% capacitive retention
was exhibited by C20%:Gd3+@α-Sb2O4 NC.

Conclusion:
The present research introduces ease of synthesis of hybrid electrode materials
possessing high active surface area, increased energy density, high cyclic stability, and reversibility
in an aqueous solution.

Introduction. The most common treatment option for prostate cancer is radical prostatectomy, which involves the removal of the prostate itself and the prostatic urethra in a single block, followed by the formation of a vesicourethral anastomosis. This approach is fraught with postoperative complications, such as urinary incontinence and strictures of anastomosis. In this sense, the clinic's staff faced the question of the possibility of a urethral-sparing variant of operative benefit for a certain category of patients.Objective. To assess the possibility of performing radical prostatectomy with sparing of the proximal prostatic urethra in the laparoscopic version, its advantages, and disadvantages.Materials & methods. From 2021 to 2022, 18 successful laparoscopic operations were performed using this technique at the St. Luke Clinical Multidisciplinary Medical Centre. Patients were selected according to the above criteria. In the preoperative period, patients underwent a standard examination in accordance with guidelines, including a blood test for prostate-specific antigen (PSA), ultrasound, magnetic resonance imaging (MRI) with 3D-modelling, data from a multifocal prostate biopsy, the International Prostate Symptom Score (IPSS), the International Index of Erectile Function (IIEF), the Quality of Life (QoL) index due to urinary disorders, assessment by the Partin’s nomogram. Intraoperative ratios, early and late postoperative complications, length of hospital stay, day of catheter removal, and time to complete urethral recovery were evaluated to study the effectiveness of this surgery type. PSA testing, uroflowmetry with post-void residual urine measurement and IPSS questionnaire were carried out one month after surgery.Results. There was an improvement in all measurements one month after surgery: median values of the mean urine flow rate increased by 1.7 ml/s, median values of the max urine flow rate increased by 3.7 ml/s, the IPSS decreased by 12 points.Conclusion. Based on the results of the study, clinical observations, and statistical analysis of the data obtained, it can be concluded that laparoscopic radical prostatectomy with sparing of the proximal prostatic urethra is the preferred surgical option for this pathology, due to its organ-preserving nature.

Introduction. Insufficient sensitivity and specificity of existing methods for diagnosing urethral stricture require more accurate methods, which may include magnetic resonance imaging (MRI).Objective. To study the possibilities of MRI to assess the extent of bulbous urethral stricture and spongiofibrosis grade.Materials & methods. The study included six men with bulbous urethral stricture, who underwent non-transecting anastomotic urethroplasty via ventral approach. Before surgery, all patients underwent retrograde urethrography according to the standard method and urethral MRI according to their own method, and their data were compared with intraoperative parameters.Results. The length of the stricture according to retrograde urethrography averaged 11.5 ± 6.3 mm, MRI — 17.8 ± 10.9 mm, intraoperative measurement — 16.7 ± 9.1 mm. There was a significant difference between the mean length of the stricture according to retrograde urethrography and the mean length according to intraoperative data (p = 0.028). There was no significant difference between the mean stricture length according to MRI data and the mean stricture length according to intraoperative data (p = 0.085). The length of spongiofibrosis according to MRI was 15.8 ± 13.6 mm on average, and 16.7 ± 12.9 mm according to intraoperative measurements. There was no significant difference between the average length of spongiofibrosis according to MRI and the average length according to intraoperative data (p = 0.092).Conclusions. MRI provides information comparable to intraoperative data on the extent of urethral stricture, location, and spongiofibrosis grade.

Introduction. One of the additional instrumental methods for diagnosing pudendal neuropathy is needle electroneuromyography (ENMG) of the bulbocavernosus reflex (BCR). The accumulated data on ENMG BCR in patients with primary chronic pelvic pain syndrome (CPPS) are insufficient due to the specificity of the procedure and its performance only in expert centres that specialise in the treatment of pelvic pain. Therefore, a study to investigate the features of ENMG BCR in patients with CPPS is of increased interest.Objective. To assess the representativeness and informativeness of the ENMG BCR technique in patients with CPPS and to identify factors influencing changes in the main parameters of the BCR M-response such as latency, amplitude, and duration.Materials & methods. Retrospective cohort study, which included 75 data from patients with (CPPS) who underwent needle-guided ENMG recording of BCR. Subjective complaints of patients were recorded using validated questionnaires: visual analogue scale (VAS) and chronic prostatitis and male pelvic pain syndrome symptom scale index (NIH-CPSI). Basic ENMG parameters such as the amplitude, latency, and duration of the M-responses were recorded.Results. We found statistically significant correlations between the duration and height of the M response of the patients (r = 0.31, p = 0.03) and their body weight (r = 0.34, p = 0.02). Anthropometric data did not correlate with amplitude and latency. Significant excess latency above 45 ms was observed, confirming nerve tissue destruction, in 11 (55%) women and 24 (44%) men. Although there were no statistically significant differences in any of the M-response parameters between men and women, there was a tendency for an increase in response amplitude in men and an increase in BCR latency time in women.Conclusion. The results of our study show that the duration of the M-response of BCR can correlate positively with the anthropometric data of the patient. At the same time, the mean latency and amplitude of the response are independent of anthropometric data, and the difference between them may be more determined by sex differences.

Published: July 2023

Introduction. The study of effective and safe combined methods of conservative treatment of idiopathic male infertility is of great interest.Objective. To evaluate the effectiveness of the combined use of low-level laser therapy (LLLT) in the infrared (IR) spectrum and bioregulatory therapy with complex prostate peptides on the semen parameters and sperm DNA fragmentation (SDNAF) in men with idiopathic infertility.Materials & methods. The study is based on the results of examination and treatment of 97 men with idiopathic infertility. Prior to the start of treatment, all patients were divided into three groups by randomization. Patients in group 1 (n = 34) underwent a course of LLLT in the IR spectrum consisting of 10 procedures q.o.d. Patients in group 2 (n = 31) were prescribed complex prostate peptides Supp. Prostatilen® AC (30 + 180 mg) PR q.h.s. FXD, with a repeat of the course of treatment after 5 days. Patients in group 3 (n = 32) underwent combined treatment: LLLT sessions in the IR spectrum (10 procedures q.o.d.) and a course of Supp. Prostatilen® AC (30 + 180 mg) PR q.h.s. FXD, with a repeat of the course of treatment with peptides according to the same scheme after 5 days. Control examination of patients in all groups was carried out two months after the end of treatment.Results. As a result of treatment of patients in groups 1, 2, and 3, a significant improvement in the main semen parameters, a decrease in the grade of pathological SDNAF, an increase in serum total and free testosterone concentration (p < 0.05) were observed. A comparative statistical analysis of the results obtained in three groups of patients showed that the combined treatment of patients of group 3, who were prescribed a course of LLLT in combination with complex prostate peptides Supp. Prostatilen® AC, was significantly more effective in improving concentration (p < 0.01) and progressive sperm motility (p < 0.01), as well as a decrease in the grade of pathological SDNAF (p < 0.05), than in groups 1 and 2.Conclusion. Combined therapy that includes complex prostate peptides and LLLT in the IR spectrum improves the main semen parameters and reduces the grade of pathological SDNAF in men with idiopathic infertility.

Published: July 2023

ABSTRACT
An organization can lose up to 5 percent of its revenue to fraud (ACFE 2020) making the ability to effectively prevent and detect accounting fraud essential to many stakeholders. Auditors typically use the fraud triangle framework consisting of pressure, opportunity and rationalization to understand fraud risks factors. The fraud diamond extends the fraud triangle to include an additional risk factor, capability (Wolfe and Hermanson 2004). This study uses an experimental task to analyze the effect of individual fraud diamond components of capability on the likelihood of committing fraud. The results show that capability components of ego, intelligence, and ability to cope with stress significantly influence the likelihood of committing fraud. Results also show including fraud diamond capability components improve the ability to predict the likelihood of fraud.
