The consequences of burnout for tertiary students across the health professions are well documented. As key stakeholders in university-offered wellbeing services and support, it is desirable for students to hold a central role in development of such resources. Hence, there is a compelling need to develop a student-driven approach to promote wellbeing in the tertiary setting. Based on this need, an online student-focused platform was developed using a bottom-up approach to support participant-driven enhancement of wellbeing and resilience to counteract burnout at a large Australian university. This study reports on the development of the initial online “student bundle”, providing a foundation to inform the design of more locally-based approaches to improve wellness and prevent burnout. Students and staff were invited to participate in a series of focus groups. Sessions sought to collect information on desired structure, resources, and overall content of the student bundle, with a thematic analysis undertaken to identify emerging themes. Focus groups were conducted separately with staff (n=17) and students (n=7). Six main themes in relation to the development of the bundle emerged: Communication/Engagement, Accessibility/Flexibility, Professional practice, Community, Awareness, and Opportunity for personal growth. Stakeholders emphasised a bundle should be engaging and proactive to address wellbeing issues; incorporate aspects linked to professional identity; and foster community, connectedness, and self-awareness, providing an opportunity for growth. Our research has exposed significant needs in relation to how an online student-focused wellbeing bundle could be delivered and what it could provide. Findings from this study will be used to guide further development and implementation of a multimodal, interactive student wellbeing bundle.

Authors: Korolev V. I. , Zvereva E. R.
Published: January 2023

PURPOSE. To consider the experience of using chemical water treatment waste in economic activity. To analyze scientific publications of Russian and foreign authors in order to determine the most popular industries in this waste and information about projects already implemented in Russia and abroad. To provide a brief analysis of the main areas of processing and disposal of sewage sludge in the world and in Russia. To assess the prospects for the use of chemical water treatment waste in the treatment of sewage sludge.

METHODS. To achieve this goal, an assessment of the environmental impact of chemical water treatment waste on the environmental situation and human health was carried out on the example of Kazan CHP-1 (KTEC-1). A number of studies of KTEC-1 carbonate sludge have been carried out to determine the granulometric and elemental composition. results. The physico-chemical composition of carbonate sludge depends on a number of parameters of the water treatment system at an energy facility: the process of liming and coagulation of water, the amount of insoluble salts, the dewatering technology used, etc. Carbonate sludge is insoluble in water, has a typical chemical composition containing calcium carbonate (CaCO3), calcium oxide (CaO), magnesium carbonate (MgCO3), magnesium oxide (MgO), iron hydroxide (Fe(OH)3), silicon dioxide (SiO2), etc.

CONCLUSION. The use of this type of technological process makes it possible to reduce the amount of calcium oxide used and replace it with calcium oxide from carbonate sludge. The use of carbonate sludge as a sediment stabilizer due to the CaO content is confirmed by laboratory studies. Due to these data, the disposal of chemical water treatment waste is ensured, less pollution of environmental objects is achieved.

Published: January 2023

THE PURPOSE. The presented work aims to optimize the operating mode of an asynchronous motor (AM) with a short-circuited rotor. To implement energy-efficient modes of operation of AM, operating in the resources of a rational electric drive, it is necessary to determine the numerical values of the parameters of the AM equivalent circuit, the currents flowing through the circuit element. There is no significance to this important definition of squirrel-cage currents, in accordance with the identification of the allocation of squirrel-cage rotor currents, which requires a solution along with the determination of the parameters of the IM equivalent circuit.

METHODS. To analyze the work of AM in technical and educational formulations, equivalent circuits are presented, which turn into circuits with serial and analytical connections of active and inductive connections. For the established and transient operating modes of AM, it is important to determine the stator and rotor currents, their active and reactive components. In this regard, it is proposed to present the IM equivalent circuit in the form of conductivities connected in parallel, which will allow determining the components of IM currents without complex mathematical models. The replacement circuit of AM consisting of a series and parallel connection of active and inductive resistances has been converted into a circuit consisting of conductances. When converting the AM equivalent circuit, no additional dependencies and coefficients were introduced, and all assumptions that are accepted for IM equivalent circuits refer to the circuit under consideration. RESULTS. It was decided to use the equivalent circuit of one phase of AM, expressed in terms of the conductivities of the stator and rotor. According to the found dependences of conductivities, for the proposed equivalent circuit, the corresponding currents and powers of the AM phase are determined. Formulate the basic principle of optimal frequency control of AM, according to the criterion of energy saving. As an indicator of the efficiency of AM operation in steady-state operating modes, the minimum value of the total losses of the engine, the value of which is determined by the ratio of the product of the active conductivity of the rotor circuit q2s and the active conductivity of the phase q to the square of total conductivity y.

CONCLUSION. Based on the results of the analysis of the characteristics of an asynchronous motor, the following conclusion was drawn: the motor will operate with minimal losses if the amplitude of the supply voltage is changed so that the slip of the asynchronous motor is equal to the critical value sξ for a given frequency. For the investigated engine AIR100S4, the critical value is sξ=0.0613 at a network frequency of 50 Hz. The method proposed in the work allows to reduce the loss of active power by 3-5% in the motor windings.

A new experimental method for evaluating the detonability of fuel–air mixtures (FAMs) based on measuring the deflagration-to-detonation transition (DDT) run-up distance and/or time in a standard pulse detonation tube (SDT) is used to rank gaseous premixed and nonpremixed FAMs by their detonability under substantially identical thermodynamic and gasdynamic conditions. In the experiments, FAMs based on hydrogen, acetylene, ethylene, propylene, propane–butane, n-pentane, and natural gas (NG) of various compositions as well as FAMs based on the gaseous pyrolysis products of polyethylene (PE) and polypropylene (PP) are used: from extremely fuel-lean to extremely fuel-rich at normal temperatures and pressures. The concept of ''equivalent'' FAMs exhibiting the same or similar detonability under the same conditions is proposed. ''Equivalent'' FAMs can be used for predictive physical modeling of detonation processes involving FAMs of other fuels. The ranking of FAMs in terms of their relative detonability allows choosing a propylene FAM for physical modeling of the operation process in the PP-fueled solid-fuel ramjets operating on detonative combustion.

Pengelolaan irigasi yang lebih efisien saat ini sangat diperlukan dalam menghadapi ketersediaan air yang semakin terbatas dan kebutuhan air untuk selain sektor pertanian yang semakin meningkat. Hal ini dapat dilakukan dengan meningkatkan ketepatan pemberian air irigasi melalui optimalisasi interval operasi irigasi. Salah satu upaya yang dapat dilakukan adalah dengan meminimalisasi waktu pelaporan operasi irigasi menggunakan perangkat lunak berbasis web Sistem Manajemen Operasi Irigasi (SMOPI). Penelitian ini dilakukan untuk mengidentifikasi waktu minimal yang diperlukan untuk pelaporan operasi irigasi, baik secara manual ataupun menggunakan SMOPI. Penelitian ini dilakukan dalam bentuk studi kasus di Daerah Irigasi Bondoyudo melalui pengumpulan data dengan cara diskusi dan penyebaran kuesioner serta analisis waktu operasi menggunakan Critical Path Method. Berdasarkan hasil analisis, pelaporan operasi irigasi secara manual membutuhkan waktu 43 jam pada tahap perencanaan tanam, 41 jam pada tahap pengaturan pemberian air, dan 45 jam pada tahap rekapitulasi hasil. Kebutuhan sekitar 5 hari pada tahap pengaturan pemberian air mengindikasikan bahwa interval operasi irigasi eksisting setiap 10 hari cukup aman. Perangkat lunak SMOPI mampu mengakselerasi waktu operasi pada tahap perencanaan tanam, pengaturan pemberian air, dan rekapitulasi hasil masing-masing menjadi 24,5 jam, 14 jam, dan 31,5 jam. Akselerasi ini mengindikasikan bahwa SMOPI dapat digunakan untuk membantu mempersingkat interval operasi irigasi dalam upaya moderinasi irigasi.
Quantitative and quantitative analysis of spleen and bone marrow CD8+ and CD4+ T cell populations in lactating mice
Authors: Panova N.
Published: January 2023

Purpose: to investigate the phenotype of adaptive immunity cells in the spleen and bone marrow of lactating mice.

Materials and methods. The studies were carried out on lactating mice. For the experiment, the spleen and bone marrow were taken from animals. A suspension of individual splenocytes was prepared by grinding the spleen. Bone marrow was obtained by rinsing the medullary cavity with a syringe with 1–2 ml of a balanced salt solution. The phenotype of adaptive immunity cells was determined using a set of fluorochrome-conjugated antibodies: CD4-PerCP-Cy5.5, CD8-PE/Cy7, CD62L-APC/Cy7, CD44-BV510 (Biolegend, USA), in the presence of True Stain reagent containing antibodies to CD16/CD32 (Biolegend, USA) to block nonspecific antibody binding. Data collection was carried out on a CytoFlex flow cytometer (Beckman Coulter, USA). The results were analyzed using the Kaluza Analysis 2.1 program (Beckman Coulter, USA).

Results. As a result of the study, it was found that there are 2.2 times more CD8+ T-cells of effector (TEM) and central memory (TCM) in the red bone marrow, while all subpopulations of CD4+ T-memory cells (TCM; TEM; TNV) predominate in the spleen . The content of the subpopulation of CD8+ T-cells of naive memory (TNV) in the bone marrow and spleen was almost the same and amounted to 52.57±1.58 % and 57.40±2.63 %, respectively. A significantly low content (p<0.001) of populations of CD8+ T-cells of effector memory (TEM; CD44+CD62L-) in the spleen was found to be 4.9±1.39 % compared with T-cells (TEM; CD44+CD62L-) of red bone marrow brain 11.04±2.58 %.

Conclusion. The population of CD4+ T-cells of effector memory (TEM) accumulates in large numbers in the spleen in order to further respond with a cellular or humoral mechanism in response to the penetration of an antigen into the body. The bone marrow quantitatively and qualitatively surpasses the spleen in the accumulation and placement of effector (TEM) and central memory (TCM) CD8+ T cells, which are responsible for immunological memory and adaptive immune response.

Purpose: determining the prognostic value of leukocyte indexes of intoxication and reactivity in fish under the action of some physicochemical stressors.

Materials and methods. The object of the study was the lady of the roach of ordinary Rutilus Rutilus (L.). Control and experimental groups were formed taking into account the principle of analogues (n = 90). The average mass (PP) is 5.29 ± 1.0 g, length (TL) - 7.22 ± 0.39 cm, fish of the juvenile period of development (the sexual structure was not installed). The individuals were accumulated (10 days) and contained the following indices in aquariums (volume - 200 l.) We examined the core index, a leukocytic index of intoxication, blood leukocyte shear index, and a leukocytal index. As physico-chemical stressors, subcutal concentrations of copper (exposition in copper salt 0.01 mg/l and 0.1 mg/l for 7 and 14 days) were studied; imitation of the main phase and the initial period of the phase of geomagnetic storm; The action of high temperature.

Results. The analysis of leukocyte indexes of intoxication and reactivity showed that in fish the Krebs index and a leukocytic index have the greatest prognostic importance. The information content of the blood leukocyte shear index and the leukocyte intoxication index should be considered controversial. The blood leukocyte shift index increased only with the exposure of copper salts for 14 days and with the action of physical stressors. Statistically significant changes in the blood leukocyte shift index during exposure by copper salts for 7 days have not been revealed, which may indicate a low sensitivity of the index. The results obtained during the calculation of the leukocyte index of intoxication are similar to the results when determining the Krebs index. Specific changes in the index under the action of physico-chemical stressors have not been identified.

Published: January 2023

Objective: Surgical treatment of endometriosis, when indicated, has demonstrated to be effective in reducing painful symptoms and improve quality of life of patients affected with endometriosis. The minimally invasive approach via laparoscopy is the preferred method when compared with laparotomy but in the last two decades another minimally invasive approach has become available, the robotically assisted laparoscopic surgery. Robotic technology is widely used in different surgical branches, such as general surgery and urology. Moreover, the use of robotic surgery is already accepted for different gynecological procedures either for benign and for oncological diseases. The advantages of robotic surgery such as improve dexterity of movements, avoided tremor, increased magnification of 3-dimensional vision seem strategic in the context of a complex surgery as is deep endometriosis eradication. However, to date there is no unanimous consensus on whether robotically assisted procedures are a valid and safe alternative to laparoscopy in the treatment of endometriosis. Mechanism: In this narrative review we analyze the available literature assessesing the robotic treatment of all types of endometriosis and specifically deep infiltrating endometriosis, compared to the outcomes of conventional laparoscopy. Findings in Brief: Indeed, the evidence of safety and effectiveness of robotically assisted laparoscopy in endometriosis treatment is strong and almost unanimous. There is no clear superiority of one approach to the other but robotic-related advantages and future prospective are promising to be able to improve operative outcomes, reduce surgeon’s fatigue and provide a technology easy to implement with a fast learning curve. Conclusions: Robotic technology applied to laparoscopy in the treatment of endometriosis could be seen as an effective and safe alternative to the conventional laparoscopic treatment.

Background: A close relationship exists between major depressive disorder (MDD) and diabetes mellitus. The metabolomic difference and similarity between patients with and without diabetes mellitus have not been well studied in the context of MDD. We aimed to examine these differences and common serum metabolomics patterns, pathways and biomarkers that can comprehensively reflect the pathogenetic difference and similarity between these MDD groups. Methods: We performed a metabolomics analysis of serum samples of healthy controls (n = 6), patients with MDD and type 2 diabetes mellitus (n = 13), and patients with MDD without type 2 diabetes mellitus (n = 27). Metabolomics analysis was conducted using capillary electrophoresis Fourier transform mass spectrometry and a candidate compound was assigned to the 496 (290 cation, 206 anion) peaks. Moreover, we evaluated the sensitivity and specificity of the candidate biomarkers for distinguishing between MDD patients with or without type 2 diabetes mellitus. Results: Principal component analysis revealed no clear distinction among the three groups, while naive partial least squares discriminant analysis yielded three relatively good and distinct populations based on the first principal component. Energy conversion by the tricarboxylic acid cycle represented the highest percentage among the top 30 positive factors of the first principal component, and glutamate metabolism and urea cycle represented the highest percentage among the top 30 negative factors of the first principal component. Synthesis and degradation of ketone bodies had high impact in MDD with type 2 diabetes mellitus group and taurine and hypotaurine metabolism had high impact in MDD without type 2 diabetes mellitus group for the pathway. Conclusions: Patterns of serum metabolites may be different among MDD with type 2 diabetes mellitus, MDD without type 2 diabetes mellitus, and healthy controls groups. Specifically, comorbid type 2 diabetes mellitus could affect metabolomics pathway and alter the distribution of serum metabolites in patients with MDD. These findings may shed light on the influence of the type 2 diabetes on the pathophysiology of MDD.

Background: Aerobic high-intensity interval training (HIIT) has demonstrated benefits for ventricular remodeling after myocardial infarction (MI) through various mechanisms. Despite this, the optimal training volume is not well known. The present study aimed to assess the effects of different (low vs. high volume) aerobic HIIT compared to an attentional control (AC) group on echocardiographic and biochemical indicators of left ventricular (LV) remodeling in adults after MI. Methods: Randomized clinical trial conducted on post-MI patients with preserved ventricular function. Participants were assigned to three study groups. Two groups performed HIIT 2 d/week, one group with low-volume HIIT (20 min, n = 28) and another with high-volume HIIT (40 min, n = 28). A third group was assigned to AC (n = 24) with recommendations for unsupervised aerobic training. Left ventricular echocardiographic parameters and cardiac biomarker levels (N-terminal pro-b-type natriuretic peptide, NT-proBNP; soluble growth stimulation expressed gene 2, ST2; troponin T; and creatine kinase) were assessed at baseline and after the intervention (16 weeks). Results: Eighty participants (58.4 ± 8.3 yrs, 82.5% male) were included. Both low- and high-volume HIIT showed increases (p < 0.05) in left ventricular end-diastolic diameter (1.2%, 2.6%), and volume (1.1%, 1.3%), respectively. Interventricular septal and posterior walls maintained their thickness (p = 0.36) concerning the AC. Significant (p < 0.05) gain in diastolic function was shown with the improvements in E (–2.1%, –3.3%), e’ waves (2.2%, 5.5%), and the deceleration time (2.1%, 2.9%), and in systolic function with a reduction in global longitudinal strain (–3.2%, –4.7%), respectively. Significant (p < 0.05) reductions of N-terminal pro-B-type natriuretic peptide (NT-proBNP) (–4.8%, –11.1%) and of ST2 (–21.7%, –16.7%)were found in both HIIT groups respectively compared to the AC group. Creatine kinase elevation was shown only in high-volume HIIT (19.3%, p < 0.01). Conclusions: Low-volume HIIT is proposed as a clinically time-efficient and safer strategy to attenuate dysfunctional remodeling by preventing wall thinning and improving LV function in post-MI patients.

Background: Cerebral computed tomography (CT) and various severity scoring systems have been developed for the early prediction of the neurological outcomes of cardiac arrest survivors. However, few studies have combined these approaches. Therefore, we evaluated the value of the combination of cerebral CT and severity score for neuroprognostication. Methods: This single-center, retrospective observational study included consecutive patients surviving nontraumatic cardiac arrest (January 2016 and December 2020). Gray-to-white ratio (GWR), third and fourth ventricle characteristics, and medial temporal lobe atrophy scores were evaluated on noncontrast cerebral CT. Simplified cardiac arrest hospital prognosis (sCAHP) score was calculated for severity assessment. The associations between the CT characteristics, sCAHP score and neurological outcomes were analyzed. Results: This study enrolled 559 patients. Of them, 194 (34.7%) were discharged with favorable neurological outcomes. Patients with favorable neurological outcome had a higher GWR (1.37 vs 1.25, p < 0.001), area of fourth ventricle (461 vs 413 mm2, p < 0.001), anteroposterior diameter of fourth ventricle (0.95 vs 0.86 cm , p < 0.001) and a lower sCAHP score (146 vs 190, p < 0.001) than those with poor recovery. Patients with higher sCAHP score had lower GWR (p trend < 0.001), area of fourth ventricle (p trend = 0.019) and anteroposterior diameter of fourth ventricle (p trend = 0.014). The predictive ability by using area under receiver operating characteristic curve (AUC) for the combination of sCAHP score and GWR was significantly higher than that calculated for sCAHP (0.86 vs 0.76, p < 0.001) or GWR (0.86 vs 0.81, p = 0.001) alone. Conclusions: The combination of GWR and sCAHP score can be used to effectively predict the neurological outcomes of cardiac arrest survivors and thus ensure timely intervention for those at high risk of poor recovery.

Left Main Coronary Artery (LMCA) disease is considered a standout manifestation of coronary artery disease (CAD), because it is accompanied by the highest mortality. Increased mortality is expected, because LMCA is responsible for supplying up to 80% of total blood flow to the left ventricle in a right-dominant coronary system. Due to the significant progress of biomedical technology, the modern drug-eluting stents have remarkably improved the prognosis of patients with LMCA disease treated invasively. In fact, numerous randomized trials provided similar results in one- and five-year survival of patients treated with percutaneous coronary interventions (PCI) -guided with optimal imaging and coronary artery bypass surgery (CABG). However, interventional treatment requires optimal imaging of the LMCA disease, such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The aim of this manuscript is to review the main pathophysiological characteristics, to present the imaging techniques of LMCA, and, last, to discuss the future directions in the depiction of LMCA disease.
PENGEMBANGAN SISTEM KALIBRASI DAYA UNTUK ALAT ELEKTROMEDIK PADA RENTANG FREKUENSI RADIO
Authors: Perangin-Angin Windi Kurnia
Published: January 2023

Alat-alat kesehatan seperti alat radiologi, alat fisioterapi dan alat elektromedik lainnya memiliki fitur berupa daya yang bekerja dalam rentang frekuensi radio. Kalibrasi daya untuk alat kesehatan elektromedik dalam rentang frekuensi radio sangat penting karena menyangkut keamanan dan kualitas dari penggunaan alat kesehatan tersebut. Kegiatan kalibrasi melalui pengukuran pada output daya dari alat fisioterapi juga diperlukan untuk mendapatkan hasil terapi yang optimal bagi pasien. Kebutuhan kalibrasi tersebut sejalan dengan Peraturan Menteri Kesehatan Republik Indonesia Nomor 62 Tahun 2017 yang menyebutkan bahwa alat kesehatan elektromedik dan radiologi perlu dikalibrasi secara periodik sesuai dengan ketentuan peraturan perundang-undangan. Belum tersedianya sistem kalibrasi daya untuk alat elektromedik pada frekuensi radio yang memadai di Indonesia menyebabkan stakeholder terkait mengirimkan peralatannya untuk dikalibrasi ke pabrik pembuat atau supplier yang memiliki ketertelusuran pengukuran di negara lain. Oleh karena itu, Badan Standardisasi Nasional yang mempunyai fungsi pengelolaan standar nasional satuan ukuran harus membangun ketertelusuran sistem pengukuran daya frekuensi radio di Indonesia. Sistem kalibrasi daya untuk alat elektromedik pada frekuensi radio telah dikembangkan dengan metode direct comparison transfer yang bekerja pada rentang frekuensi 10 MHz sampai dengan 3 GHz. Modifikasi pada metode direct comparison transfer telah menghasilkan pengukuran alat kesehatan elektromedik yang lebih akurat, dan ketidakpastian pengukuran yang lebih kecil. Sistem kalibrasi tersebut telah digunakan untuk kalibrasi alat elektromedik pada rentang frekuensi radio yang berfungsi untuk menunjang kesehatan masyarakat.

Published: January 2023

The study of the activities of Muslim institutions in the field of regulation of social relations in a secular state is of particular interest in terms of religious associations’ adaptation. The authors explore the structure of the Qadiyat of the Muslim Religious Board of the Republic of Tatarstan, the powers of qadis, the main directions of their activities and give examples of the consideration of cases by Muslim judges, analyzing regulations and publications within the framework of the structural-functional approach. Tatarstan qadis as members of the Qadis Council and as regional Muslim judges perform control, advisory, mediation and arbitration functions. Qadis deal with marriage and family matters, inheritance disputes, settle conflicts in the business sphere, consult on Sharia issues and are engaged in the preservation and strengthening of Tatar traditions. One of the promising directions for the development of the institution of Qadiyat as an instrument for pre-trial settlement of disputes is the creation of a mediation and arbitration body on its basis that can help a wide range of believers to resolve conflicts according to the norms of Islam and Russian laws.

The article provides an overview of the history, current state, trends and prospects for the development of the field of knowledge and practice at the intersection of Islam and Psychology in selected countries of the post-Soviet space in line with global trends in Islamic Psychology and the historical, social, political and legal contexts that are characteristic of these countries. An analysis of the modern context, historical experience and existing developments of the Soviet and post-Soviet periods allowed the authors to identify the general and the particular in the theory and practice of Islamic Psychology in the countries under consideration, as well as to assess the prospects for its development.

The authors state that the development of the problems of Islam and Psychology in the Russian Federation has a solid academic and practical basis for the further development of Islamic Psychology and the provision of psychological assistance to Muslims based on the Islamic tradition. Based on a detailed analysis of a number of areas of activity (scientific, educational, consulting, etc.) in this area, it is indicated that in Russia the field of Islamic Psychology is developing at a faster pace than in other CIS countries. It is noted that the Russian model can serve as a kind of example for the development of Islamic Psychology in these countries (Azerbaijan, Kazakhstan and the states of Central Asia), which in many ways follows the pattern of the Russian Federation with relevant regional specifics and has great opportunities and prospects, given that the majority of the population of these countries belongs to Muslims, who have historically deep roots of Islamic culture and religion.
