Level Up! Lessons Learned from Six Years of Collaborative Technical Skills Development
Authors: Eckard Max , Gadelha Elizabeth , Shallcross Mike
Published: December 2022

As academic and cultural heritage institutions increasingly offer digital collections and services, technical upskilling—the process of acquiring and/or expanding technical skills—has moved from an individual prerogative to an institutional imperative. In this publication, the authors share their experiences with, and lessons learned from, a series of four collaborative technical skills development initiatives—the ArchivesSpace-Archivematica-DSpace Workflow Integration Project (2014–2016), a series of Curation Team Workshops (2015), a Technical Skills Pilot Project (2017–2018), and the development of a Bentley Audiovisual Quality Control Utility (2019)—at the University of Michigan Bentley Historical Library. In doing so, the authors advocate for the value of increasing the technical literacy and skills of entire teams/units (as opposed to focusing on the development of individual skills) and provide information and best practices that will enable and empower other institutions to undertake similar initiatives. They conclude by making the case for organizational cultures that value learning together.
Redesigning Program Assessment for Teaching with Primary Sources: Understanding the Impacts of Our Work
Authors: Hoyer Jen , Holt Kaitlin , Voiklis John , Attaway Bennett , Joy Norlander Rebecca
Published: December 2022

This article describes how redesigning a program's assessment practices for teaching with primary sources (TPS) can provide a clear framework for talking about the impact of educators' work in archives and can provide feedback on how to refine instruction practices for greater results. The authors share a description of their assessment redesign process accompanied by analysis of the implementation of our new assessment tool in the hope others will consider the design and goals of their own assessment practices. The authors' work demonstrates that reflection on existing tools, development of new goals, and design of new assessment strategies can yield inspiring new data on program impact and highlight areas for improvement. By illustrating the authors' redesign process, this article also demonstrates the types of impacts and outcomes that educators can measure for TPS and points to the huge potential of TPS in local history contexts and elsewhere. The authors' revised student assessment moved archives staff from relying on self-reported, affect-focused data to better understanding the outcomes of their work with students: the impact of project-based learning in archives; the value that students find in various aspects of their encounters with archives; the role that TPS in local history contexts plays in connecting students to their community; and the transferability of research skills that students learn through TPS activities.
Reference Staffing and Scheduling Models in Archives and Special Collections: A Survey Analysis of Prepandemic Practices
Authors: Hawk Amanda K.
Published: December 2022

Reference services form the core function of any type of library. Even when faced with shrinking budgets and staff sizes, library and archives workers continue to provide reference services to meet the demands of researchers. Yet a critical analysis of the internal systems used for archival and special collections reference work is lacking compared to the robust body of research about users of collection materials. This article presents findings from a national survey about reference staffing and scheduling models in archival and special collections repositories conducted immediately prior to the onset of the COVID-19 pandemic. The survey data revealed specific models for staffing and scheduling used by participating institutions, respondents' level of satisfaction with staffing and scheduling models, and the most common challenges and successes related to reference services. The responses also conveyed information about the number of special collections and archives staff participating in reference services, the average length and frequency of shifts, and typical service hours. The findings indicated overall satisfaction among respondents in terms of their unit's staffing and scheduling models, with larger institutions reporting higher satisfaction rates across all categories than smaller institutions. Yet many survey participants reported budget constraints and staffing shortages that negatively impact public services operations. Although the results do not pinpoint a single approach to reference staffing and scheduling that will work for all archives and special collections units, qualitative responses suggest that successful reference models depend on sufficient staffing, internal buy-in and cooperation among employees, and support from supervisors and administration.
Toward Metaliteracy and Transliteracy in the History Classroom: A Case Study Among Underserved Students
Authors: Cobourn Alston Brake , Brown Jen Corrinne , Warga Edward , Louis Lisa
Published: December 2022

In the last twenty years, scholars have reimagined information literacy to better address an overly saturated world of information and the growing participatory culture of Web 2.0. Outside of library and information science (LIS), researchers have promoted transliteracy—the intersection between information, visual, digital, and other literacies—to help students find and assess information. Within the LIS discipline, metaliteracy has provided a foundation to rethink information literacy frameworks, redefining students as creators who produce and share information. Relatively few studies exist, however, on how to leverage literacies in support of student digital scholarship projects. Likewise, digital humanities professors promote metaliteracy in the classroom, yet fewer scholars create digital humanities projects or write case studies about them outside of research institutions, prestigious private colleges, and larger, well-established public history programs. This case study examines a class project for a small undergraduate Introduction to Public History course at Texas A&M University–Corpus Christi (TAMU–CC), a regional university with a comparatively large population of historically underserved students. Working with one archivist, two librarians, and the professor, students established a digital home for the ongoing South Texas Stories oral history project. Through this project, students learned and practiced various aspects of primary source literacy, information literacy, visual literacy, and digital literacy. The authors argue that such digital projects promote both metaliteracy and transliteracy, offering students a holistic learning experience during which they can practice their skills and that these types of projects are feasible at all kinds of institutions, even those with largely historically underserved populations.
Professional Career Building in the Archival Field: Studying the Archives Leadership Institute
Authors: Soyka Heather
Published: December 2022

This article explores the ongoing and long-term impacts of programs that support new modes of professional growth, particularly cohort-based programs that focus on the goals of community and network building, through a case study of the Archives Leadership Institute (ALI). This study seeks to understand how and why programs such as ALI assist and support archivists with their professional careers and wonders about the ways in which the profession benefits more broadly from programs like this. Ultimately, this article finds that programs such as ALI often benefit the professional careers of individual archivists, but that the broader impact for the field merits additional consideration and thought. Finally, this article draws together patterns, feedback, challenges, and suggestions for thinking about and developing future initiatives that support the growth of the archival field.

In this study, we define a new type of Pell and Pell-Lucas numbers which are called dual-Gaussian Pell and dual-Gaussian Pell-Lucas numbers. We also give the relationship between negadual-Gaussian Pell and Pell-Lucas numbers and dual-complex Pell and Pell-Lucas numbers. Also, some sum ve product properties of Pell and Pell-Lucas numbers are given. Moreover, we obtain the Binet’s formula, generating function, d’Ocagne’s identity, Catalan’s identity, Cassini’s identity and some sum formulas for these new type numbers. Some algebraic proporties of dual-Gaussian Pell and Pell-Lucas numbers are investigated. Futhermore, we give the matrix representation of dual-Gaussian Pell and Pell-Lucas numbers.
Synthesis, Structural Characterization and Investigation of DNA/BSA Binding Properties of a Homo-disulphide Schiff Base Compound Carrying Oxo Propargyl Group
Authors: KÖSE Ayşegül
Published: December 2022

In this work, a new homo-disulphide Schiff base compound (HDSB) was prepared and its structure was characterised by common spectroscopic and analytical methods. The compound was obatined from the condensation reaction of 2-aminothiophenol and 2-hydroxy-4-(prop-2-yn-1-yloxy)benzaldehyde in benzene. In the reaction, both Schiff base condensation and oxidation of thiols into disulphide formed. The isolated compound was structurally characterized by single crystal X-ray diffraction experiment. The homo-disulphide Schiff base compound (HDSB) was screened for its DNA/BSA binding properties using UV-Vis absorption and emission spectral studies. The compound showed considerable binding affinity to double-stranded fish sperm DNA (FSds-DNA) with binding constant of 4.1 × 104 M-1. Spectral measurements suggest that HDSB interacts with DNA in a minor groove binding mode. The compound also showed binding properties towards BSA (bovine serum albumin). The incremental addition of HDSB to the BSA solution resulted in a significant decrease in the characteristic emission band of BSA in the range of 320-500 nm (λexc: 280 nm) showing the binding interactions between HDSB and BSA.
Calculation of One- and Two-Center Overlap Like Quantum Similarity Integrals over ψ^((α)) Exponential Type Functions
Authors: ŞAHİN Ercan
Published: December 2022

One- and two-center overlap like quantum similarity integrals over ψ^((α)) functions are evaluated using the one-center expansion method. These integrals are expressed through expansion coefficients and usual two-center overlap integrals. The expressions derived in this work have no restrictions for the values of orbital parameters, quantum numbers and internuclear distances. Since these integrals of ψ^((α)) functions are calculated for the first time, the comparison is made with literature values obtained from Slater type functions. The computation results are in good agreement with literature values. The algorithm presented in this study could be useful when exponential type functions are employed in quantum similarity measures of atomic and molecular systems.

Access the quality and sufficient amount of water is started to being problem with population increasing. One of the way to behalf the solution of this problem is usage waste water treatment in industry and agriculture. Wastewater treatment methods have disadvantages of being costly and producing secondary pollutants, photocatalysis, which is one of the advanced oxidation methods that is more advantageous and effective in removing pollutants, is promising. The newest member of nanomaterial, C-quantum dots (CQDs) has been increasingly get attention on lots of field including photocatalyst. Semiconductors are commonly used in photocatalysis however, they have electron pair recombination problem that results decreasing of efficiency. Doping semiconductors with different nanomaterials is one of the easiest ways to get over the problem. Recently CQDs has been started to used as dopping agent. Solvothermal method is among the easiest and environmentally friendly methods in nanomaterial synthesis. In this study, the effect of dimethylformamide, dimethylsulfoxide, ethylene glycol and water as solvothermal solvent on the photocatalytic efficiency of C-modified ZnO nanoparticles (CQDs@ZnO NPs) was investigated for the first time in the literature. Photocatalytic performance of CQDs@ZnO NPs was investigated on the photocatalytic degradation of methylene blue (MB). Angora mohair has been used as a CQDs source for the first time in the literature. Photocatalytic degradation performances of CQDs@ZnO NPs for MB at 300 min were 82.4%, 87.6% and 99% for ethylene glycol-water mixture, DMSO and DMF, respectively. The results proved that solvent type for solvothermal synthesis procedure has important role for photocatalytic performance of CQDs@ZnO NPs.

Published: December 2022

The neurological process in diabetes is not limited to peripheral nerves but also affects the central nervous system (CNS). In addition, magnetic resonance images (MRI) showing that this condition can occur early in the neuropathic process are also available. This study was conducted to investigate whether peripheral sensory nerve dysfunction causes changes in thalamus volume in patients with diabetic polyneuropathy (DPNP) who experience sensory loss. Our study is a retrospective study consisting of diabetes mellitus (DM), DPNP and a healthy control group, where brain MRI of 204 individuals aged between 20-90 with no neurological disorder that might affect thalamus. Morphometric measurements for thalamus and cerebrum volumetry were performed in conventional MRI. In order to measure the microstructural changes of thalamus, the apparent diffusion coefficient (ADC) was calculated by the diffusion-weighted imaging method. In conclusion of our measurements, it was found that individuals with DM and DPNP had a decrease in volume of both thalami(p<0.05) and cerebrum(p<0.05). However, no significant difference was found in ADC values(p>0.05). According to the results of research, DM and DPNP affect not only the peripheral nervous system but also the CNS. This effect caused atrophy of thalamus and cerebrum in patients of all age groups.

Authors: BIÇAK Bilge , GUNDUZ Serda Kecel
Published: December 2022

Hypertension is a serious risk factor for various diseases. Therefore, lowering and preventing high blood pressure is a significant issue. Blockage of the renin-angiotensin-aldosterone system (RAAS), which controls blood pressure, is important to reduce blood pressure and consequently reduce symptoms of heart failure. This blockage can be carried out by angiotensin-converting enzyme (ACE) and angiotensin II receptor blockers (ARBs). The phenylalanyltyrosine (H-Phe-Tyr-OH, Phe-Tyr, L-Phe-L-Tyr, L-phenylalanyl-L-tyrosine) dipeptide examined in this study is an important structure that shows blood pressure lowering properties. For this reason, the potential of the peptide to be an ACE inhibitor or ARB was investigated. The molecular activity of the Phe-Tyr dipeptide was compared with antihypertensive drugs using theoretical calculations. Molecular docking method, one of these theoretical methods, has a considerable process in illuminating biochemical processes by investigating the interactions of drugs (ligands) with targeted receptors. In this theoretical study, molecular docking analyses of H-Phe-Tyr-OH dipeptide with ACE and Angiotensin II type 1 receptor (AT1R) were implemented. The interaction types and interaction regions of the peptide were also determined in comparison with drug molecules (Captopril, Enalapril, Telmisartan and Eprosartan) that are ACE inhibitors and ARBs. Lastly, ADME (absorption, distribution, metabolism, and excretion) analysis of the H-Phe-Tyr-OH dipeptide was also performed to estimate its drug potential. In this study, the pharmacokinetic properties of Phe-Tyr dipeptide and its mechanism of action with ACE and AT1R were investigated for the first time by molecular docking and ADME calculations.

Authors: ÖZER Gülizar , YILDIZ Çağlar , ÖZER Hatice , ÇETİN Ali
Published: December 2022

Low molecular weight heparins (LMWHs) have been used for the treatment for recurrent pregnancy loss (RPL) for a long time. We aimed to investigate the efficacy of the LMWHs on angiogenesis and apoptosis during placentation. A total of twenty-four rats were randomly divided into three groups each containing 8 rats: normal saline; enoxaparine sodium 0.4 ml, and enoxaparine sodium 0.8 ml were given to the Group 1, 2 and 3, respectively. Normal saline and enoxaparine sodium 0.4 ml or 0.8 ml were given to the rats beginning on the day the pregnancy was detected and continued until the 15th day of the pregnancy. The tissues containing placental decidual zone were immunostained for vascular endothelial growth factor A (VEGF-A) and caspase 7. The decidual and placental VEGF-A and the decidual caspase 7 immunostaining scores of all of the groups were high, however, there were no statistically significant differences among the groups (p>0.05). On the other hand, the placental caspase 7 immunostaining scores of the normal saline group were significantly lower than those of the enoxaparine sodium 0.4 and the enoxaparine sodium 0.8 groups (p<0.05). LMWHs seem to have effects on placental angiogenesis and apoptosis.

Published: December 2022

This study is focused on developing a sensitive analytical method for Venlafaxine molecule which is antidepressant drug belonging to the serotonin-noradrenaline reuptake inhibitors (SNRI) group. With this study, a separation and preconcentration method based on fabric phase sorptive extraction(FPSE) method was developed for low levels of Venlafaxine in urine samples. Experimental variables such as pH, ionic strength, desorption solvent, and other parameters were studied and optimized step by step. The linearity of method under optimized conditions is in the range of 15.00-750.00 ng mL-1 while limit of detection is 4.28 ng mL-1. The relative standard deviation (RSD %) obtained from model solutions containing 300 ng mL-1 of Venlafaxine was lower than 3.1 % and pre-concentration factor was calculated as 62.50 for target molecule. In order to test accuracy of the method, recovery tests were carried out by means of spiked urine samples. As a result of recovery tests, quantative values were obtained in the range of 97.5-104.2 % successively.
The Complete Mitogenome of Redheaded Pine Sawfly, Neodiprion lecontei (Hymenoptera: Diprionidae): Duplication of trnR Gene and Rearrangement in the ARNS1EF Gene Cluster
Authors: KORKMAZ Ertan Mahir
Published: December 2022

Neodiprion is a genus belonging to the small sawfly family Diprionidae, feeding the plant family Pinaceae entirely. Here, the complete mitogenome of the redheaded pine sawfly Neodiprion lecontei (Hymenoptera: Diprionidae) was assembled, annotated as third party annotation from the raw genome dataset of N. lecontei and comparatively characterised. The length of N. lecontei mitogenome was 16,067 bp in size, with an AT content of 81.32%. The initiation codons of protein coding genes (PCGs) are ATN (except for nad6 (TTA-Phe), while termination codons are TAA or T−. tRNA genes favoured usual anticodons except for trnS1 which preferred an unusual anticodon GCU. Compared with the Neodiprion sertifer mitogenome, the ARNS1EF gene cluster was rearranged as RAS1RNEF and trnR gene has a duplicated copy, revealing a new event not formerly reported in Symphyta. The phylogeny confirms the position of N. lecontei within the family of Diprionidae and supports the monophyly of included genera and families in Tenthredinoidea.
Predictors of Self-Harm Types in Members of Online Communities: Age As a Moderating Variable
Authors: Razvaliaeva Anna Yu. , Polskaya Natalia A.
Published: December 2022

BACKGROUND: Deliberate self-harm includes direct and indirect behaviors that cause harm to the body. Various manifestations of such behavior (e.g., non-suicidal self-injuries) are prevalent in adolescent and youth populations, and they often serve as precursors of subsequent suicidal behavior. The interpersonal dynamics that lead to self-harm behavior remain understudied. Interpersonal sensitivity, defined as an anticipation of criticism and fear of rejection in ones relationships with other people, may become one such factor.
AIM: The present study was conducted to investigate the relationship between interpersonal sensitivity, psychopathological symptoms, and types of self-harm.
METHODS: The sample (n=804, 1735 years, M=23.34.6 years) was recruited in online communities. A survey developed by the authors was used to measure the types of self-harm. Other measures included the Interpersonal Sensitivity Measure and Symptom Checklist-90-R.
RESULTS: It was discovered that superficial self-injuries could be related to more severe types of self-harm, destructive for the body on the whole (e.g., risk-taking, deprivation, fasting, substance abuse). Fear of rejection and psychopathological symptoms emerged as predictors of both superficial self-injuries and self-destructive behavior. Although younger respondents (1719 years old) were more likely to inflict on themselves superficial self-injuries, those who scored high on fear of rejection were more likely to report more severe self-destructive behavior. Acute psychological distress elevated this risk for both younger and older participants (2735 years old).
CONCLUSIONS: The results of the study point at the important role the dynamics of interpersonal relationships plays in perpetuating self-harm.

Published: December 2022

Background. Ischemic heart disease, despite ongoing therapeutic and preventive measures, remains the leading cause of disability and mortality in people of working age.
Aim. Study of cardiovascular risk factors and assessment of the clinical and angiographic picture in patients with stable coronary heart disease and borderline coronary artery stenoses of various clinical phenotypes.
Material and methods. 236 patients with functional class IIII stable angina pectoris aged 4959 years with borderline (4070%) coronary artery stenoses were examined. All patients underwent a general clinical examination, cardiac ultrasound and coronary angiography. The nonparametric MannWhitney U-test was used to compare indicators between groups. To compare binary and categorical indicators, Fisher's exact two-tailed test was used. Differences in the compared parameters were considered statistically significant at p 0.05.
Results. The predominance of the following clinical phenotypes, which determined the further distribution into groups, was revealed: coronary heart disease without myocardial infarction the first group; coronary heart disease with myocardial infarction more than 6 months old the second group; coronary heart disease with a metabolically unhealthy phenotype of obesity without diabetes mellitus the third group, coronary heart disease with diabetes mellitus the fourth group. In the third and fourth groups, there was no significant difference in the frequency of myocardial infarction in the past, and patients in the third group with a history of myocardial infarction suffered it at the earliest age (44.3 [41; 50] years, p 0.01). Despite the presence of arterial hypertension in 97.5% of groups of patients with different phenotypes, the fourth group showed the highest values of the left ventricular myocardium mass index (240.6 [146.3; 286.3], p 0.01). In the same group, multivessel coronary artery lesions were more frequently recorded during angiographic examination in 25 patients (47.2 [33.4; 52.3]%, p 0.01).
Conclusion. Despite the absence of obstructive coronary artery disease, patients with stable coronary heart disease and borderline coronary artery stenoses are at risk of cardiovascular complications due to the presence of arterial hypertension in the vast majority, a significant incidence of obesity, dyslipidemia, and carbohydrate metabolism disorders.
Peculiarities of Temperament and Character of Patients with Comorbid Psychiatric Pathology and Combined Dependence on Psychostimulants and Other Psychoactive Substances
Authors: Poplevchenkov Konstantin N. , Agibalova Tatyana V. , Buzik Oleg Zh. , Mischenko Denis A.
Published: December 2022

INTRODUCTION: According to official statistics, there is an annual increase in the production and consumption of various psychostimulants, and as a result, an increase in the number of patients with addiction of psychostimulants. At the same time, there are no effective methods of treating such disorders within the framework of a modern personalized approach to therapy.
AIM: To study peculiarities of the temperament and character of patients with combined dependence on psychostimulants and other psychoactive substances (PASs) and with comorbid psychiatric pathology to increase the effectiveness of psychotherapeutic methods in personalized therapeutic approach.
MATERIALS AND METHODS: The study included 325 patients (ethnic Russian men and women aged from 18 to 50 years) with the diagnosis: dependence on psychostimulants and dependence on psychostimulants in combination with comorbid psychiatric pathology, who signed the informed consent. R. Cloninger method of assessment of the temperament and character (Temperament and Character Inventory, TCI-125) was used.
RESULTS: Patients were divided to groups depending on PASs used by them and the existence of comorbid psychiatric pathology. Of temperament dimensions, the novelty seeking predominated in all the groups (up to 15 points; р 0.002) in comparison with harm avoidance (up to 10 points; р 0.112), reward dependence (up to 9 points; р 0.442) and persistence (up to 3 points; р 0.226). This combination of temperament dimensions corresponds to antisocial personality disorder. High cooperativeness (17 points; p 0.005) was observed in patients with a full course of rehabilitation and remissions up to 12 months. The maximal self-transcendence (10 points; p 0.02) corresponded to psychiatric pathology.
CONCLUSION: On the basis of the results obtained, personality profiles of patients were determined. Patients of the first profile with dependence only on psychostimulants with minimal novelty seeking dimension of the temperament along with high cooperativeness character trait were more communicative, adapted to the treatment and rehabilitation program, and had longer remission periods. Patients of the second profile with a combined dependence on psychostimulants and other PASs with maximal novelty seeking dimension in the temperament along with minimal values on the character scales required the maximal effort of the specialists to keep them in the treatment and rehabilitation program. Patients of the third profile with dependence on psychostimulants and comorbid psychiatric pathology with maximal novelty seeking dimension in the temperament together with maximal self-transcendence were characterized by suspiciousness and required a special gradual establishment of psychotherapeutic contact to involve them in the treatment and rehabilitation process.

Published: December 2022

INTRODUCTION: The range of antiseptic agents used in clinical practice, is rather wide. However, only single studies are devoted to comparative characteristics of their effectiveness in the conditions of the oral cavity.
AIM: To choose the optimal antiseptic dental cleaner by experimental study.
MATERIALS AND METHODS: An aqueous solution of Furacilin (0.02%), chlorhexidine bigluconate (0.05%), Miramistin (0.01%), cetylpyridinium chloride (0.05%), hydrogen peroxide (3%), Iodinol, Rotokan, distilled water were used as washing liquids for elimination of dental plaque. The model of the dentition was created from quartz plates with an imitation of fresh plaque. Biomaterial imitating dental plaque included two solutions: 1) a strong fresh infusion of black tea leaves, cooled to +25C; 2) oatmeal jelly with temperature from +60C to +65C. The authors method of screening dental cleaners was used, based on comparing the transparency of the laboratory model of the dentition before and after exposure to the test solution by determination with an amperemeter of strength of the electric current in the photosensor device from the oxyhemograph sensor after white light emitted by a mini-emitter passed through biological material and plates and fell on it.
RESULTS: The cleaning capacity of distilled water is the lowest (p 0.050.001). Rotokan, Furacilin and Iodinol have a low cleaning capacity, and Iodinol can cause a burn of the gingival cuff in case of high reaction to it, and allergic reactions. Hydrogen peroxide has an average degree of efficiency, but it dries the oral mucosa. Chlorhexidine bigluconate has the highest cleaning effect, Miramistin and cetylpyridinium chloride are slightly inferior to it (p 0.05). By the cleaning capacity, chlorhexidine bigluconate solution is significantly superior to hydrogen peroxide (p 0.05), Iodinol (p 0.02), Furacilin (p 0.02), Rotokan (p 0.01).
CONCLUSION: The described method received the patent for invention of the Russian Federation No. 2019121293. Experimental studies have shown the best cleaning effect of 0.05% solution of chlorhexidine bigluconate.
Achievements and Prospects for Vascular Surgery in Treatment of Vertebrobasilar Insufficiency
Authors: Kondaraki Artur V. , Chupin Andrey V. , Alekyan Bagrat G. , Kul'bak Vladimir A.
Published: December 2022

Vertebrobasilar insufficiency (VBI) remains an important problem in the modern medicine since approximately every fourth cerebral infarction occurs in the posterior circulation of the brain. These strokes are accompanied by severe consequences and a high risk of repeated events. The article presents the current concepts for surgical treatment of lesions of the subclavian (ScA) and vertebral (VA) arteries responsible for the development of VBI. In the open surgical treatment of symptomatic lesion of the ScA, primarily of occlusion one, extrathoracic interventions prevail in the form of carotid-subclavian bypass and carotid-subclavian transposition. According to our analysis, the results of carotid-subclavian transposition prove to be more preferable. In the endovascular intervention on the ScA, balloon angioplasty is used with possible stenting. In the analysis, we found no differences in the long-term patency between angioplasty and stenting, although the extent of technical success was higher in the group of stenting. In case of stenosis of the ScA, the world medicine gives priority to endovascular methods. To date, there are no sharply defined criteria permitting to choose between the open and endovascular interventions for treatment of the ScA occlusion, although a probable technical failure of endovascular revascularization and higher long-term patency give priority to open surgery. As for symptomatic stenosis of VA, to date there is no evidence of the advantage of stenting over conservative therapy. Thus, surgical intervention should rather be used in case the drug treatment is ineffective. The same can be said about the open reconstruction of the VA, except for the cases of contraindications for stenting of the VA, for example, its tortuosity.

Published: December 2022

INTRODUCTION: Surface water sources play an important role in supply of large cities with water. Their waters are subject to anthropogenic pollution with different chemical compounds which may be significant risk factors for the health of the population. The article presents the results of comparative sanitary-hygienic characteristics of the water quality of the Oka river in places of water intake of utility and drinking water supply system of Ryazan. Being the only surface source of water supply, the Oka river provides 53% of the total water consumption of the Ryazan population, therefore a rational choice of the place of water intake can have a considerable impact on the effectiveness of water conditioning and purification and on the final quality of drinking water.
AIM: To give a comparative sanitary-hygienic characteristic of the water quality of the Oka river in places of the water intake of the utility and drinking water supply system of Ryazan.
MATERIALS AND METHODS: A comparative evaluation of the water quality of the Oka river, as a surface source of water supply, was carried out based on the average long-term values of control parameters (organoleptic, microbiological, chemical) and the proportion of samples that do not meet hygienic standards in the sections of three water intakes in Ryazan in 20122019. The average parameters were compared by the method of variance analysis; for paired comparisons, Scheffe and Tamhein criteria were used, taking into account the results of Levene test. The statistical parameters were calculated in SPSS Statistics 19 program.
RESULTS: The chemical composition of the Oka river water was characterized by the greatest pollution with iron (2+) and aluminum. The water of Oksky and Borkovskoy water intakes was characterized by higher average concentrations of iron (2+) and ammonia, as well as greater contamination with generalized and thermotolerant coliform bacteria, compared with the water of Sokolovsky water intake.
CONCLUSION: A lower initial quality of the water in Oksky and Borkovskoy water intakes may be due to their location in the 'blind' river course characterized by the processes of eutrophication and slowed down water exchange. High concentrations of iron (2+) may be associated with supply of stream water from the underground sources or with anthropogenic pollution.

Published: December 2022

According to the world literature, congenital malformations of the upper limb are found in 2.37.9 per 10 thousand live births, while anomalies in the development of the hand occur in 6595% of patients, the most common are reduction anomalies (brachydactyly, ectrodactyly, adactyly, hypoplasia). Various methods of reconstructive plastic surgery are known in the world literature, including microsurgery, compression-distraction osteosynthesis, various types of skin, tendon-muscle and bone plasty, as well as prosthetics. Non-vascularized toe phalanges transplantation is a less common method, which is effective and technically accessible in case of reduction anomalies of the hand. This study is aimed at studying the relevance of the application of the presented method based on the analysis of world literature. The aim of the review is the analysis of the world experience of using non-vascularized toe phalanges transplantation in case of congenital hand malformations. A search was made for literature sources in the open electronic databases PubMed and eLibrary for the last 110 years. The publications devoted to the study of the effectiveness of transplanting the phalanges of the toes into defects of the fingers in clinical practice are analyzed. This method has a number of advantages: low morbidity for the donor foot, minimal risk of resorption of the transplanted graft, restoration of the anatomy of the formed finger, preservation of blood supply and sensitivity in the formed finger, the possibility of phalanx growth while maintaining the growth zone, the functionality of the fingers. At the same time, such issues as the detailed functioning of the growth zone of the non-perfusion phalanx after its transplantation, the reasons for the continuation or cessation of growth in the short term after surgery, the resorption of displaced phalanges, and the dependence of the mobility of the reconstructed fingers on the technology of interventions are not indicated anywhere. Conducting further research on the role of transplantation of non-vascularized toe phalanges in the pathology of the hand in children seems to be an actual task.

BACKGROUND: The death of bone tissue cells with impaired blood supply, followed by the development of secondary arthrosis/arthritis of the adjacent joint, is most characteristic of osteonecrosis of the femoral head. This condition is common in young patients mainly in men of working age. Hip arthroplasty at a young age has a high risk of loosening of the endoprosthesis components, which can lead to many repeated surgical interventions. In recent years, hypotheses about the possible role of infectious agents in articular pathology have been discussed, as evidenced by the detection of specific antibodies and antigens of pathogens in the joint fluid and periarticular tissues. Mycoplasmas can trigger the development of osteonecrosis because the bone marrow is the main depot and source of endogenous reinfection (when immunity is weakened).
АIM: This study aimed to identify signs of the presence of mycoplasmas in the soft tissues of the hip joint and bone marrow of the femur during hip arthroplasty in patients with idiopathic avascular necrosis of the femoral head.
MATERIALS AND METHODS: Clinical and laboratory data of 36 patients with idiopathic aseptic necrosis of the femoral head who underwent total hip arthroplasty were analyzed, and 11.1% of the patients had a history of sexually transmitted diseases. The tissues of the synovium and bone marrow were examined by polymerase chain reaction for the presence of DNA to sexually transmitted infections.
RESULTS: The average age of the patients was 42.7 years, and the average period from disease onset to the time of surgery was 46.2 months. Bilateral joint damage was found in 78% of cases, and 91.7% of the patients had stage 4 femoral head disease (ARCO). The preoperative Harris score was 33.7 points on average. In history, 4 (11.1%) patients had sexually transmitted diseases. During the study, when analyzing tissue samples of the synovial membrane and bone marrow, DNA fragments of Chlamydia trachomatis, Mycoplasma genitalium, Ureaplasma spp., and M. hominis were not isolated in any case, including in patients with previous mycoplasma and chlamydial infection.
CONCLUSION: The absence of mycoplasma suggests that a history of sexually transmitted diseases does not significantly affect the outcomes of hip arthroplasty in aseptic necrosis of the femoral head.

Published: December 2022

While the increase in the customer failure rate in the consumer electronics sector affects the manufacturers negatively in terms of cost. It has also become one of the issues that cause customer loss and customer satisfaction. In addition to the economic losses, during the production and distribution of the spare parts and products that are changed at the customer's home due to the reliability problems experienced in the field, extra carbon emissions are released to the nature for this operation. For these reasons, it has become important to reduce the rate of customer failure.

With the increase in electronic components, the quality and reliability precautions that may occur in the electronic circuits, have become the subject of study today. As in many white goods products, it is advantageous to have variable speed motors in refrigerators due to energy efficiency and energy regulation issues. For this reason, the compressor of refrigerator comes to the forefront as the component that dissipates the highest power proportionally. With the use of variable speed compressors, the need for an electronic board with including power conversion and motor driving capability has arisen.

In this paper, RC Snubber circuits have been studied in order to prevent quality problems that may occur due to high switching frequency in flyback converter topology, which is one of the DC-DC converters that provide isolation. The methods in the literature based on the location of the RC Snubber in the circuit and the determination of its related values were examined and experiments were made on the simulation program. At the same time, a test mechanism was set up on the variable speed compressor motor control card of the refrigerator and measurements were taken with the help of an oscilloscope. The measurements taken in the simulation program and the experimental environment were compared.
Servidores del partido mismo. Sintonías y desencuentros entre lo político y lo judicial en el constitucionalismo español
Authors: Solla Sastre María Julia
Published: December 2022

El artículo aborda desde una perspectiva histórica la relación que se ha mantenido entre la política y la justicia en España en el marco de la separación de poderes implantado por los constitucionalismos decimonónicos. Para poder afrontar esa vinculación política-justicia se ha optado por materializar lo político y lo judicial en dos de sus expresiones institucionales, entendiendo por lo primero el Gobierno y por lo segundo la Administración de Justicia como aparato. De este breve recorrido, que abarca desde el primer constitucionalismo doceañista hasta la vigente norma constitucional, se deduce que la politicidad de la magistratura se incorporó en los albores constitucionales como un elemento básico para asentar el nuevo orden; se consagró como un aspecto sustancial de los jueces que sirvió para articular el aparato judicial, y solo en décadas muy recientes, con una verdadera democratización del constitucionalismo, se crearon instrumentos para considerarla una anomalía del sistema incompatible en esencia con una separación de poderes estructurante del orden constitucional.
Política, independencia y autogobierno judicial: Cuatro miradas
Authors: Bustos Gisbert Rafael
Published: December 2022

En este ensayo se examina la cuestión del autogobierno del poder judicial desde la óptica de la independencia judicial entendida esta como un principio con tres vertientes: subjetiva (como derecho), objetiva (como principio de organización del Estado) y estatutaria (como principio inspirador del estatuto jurídico de los jueces). El autogobierno sería el elemento básico de la dimensión objetiva de la independencia judicial. El estudio se articula desde cuatro puntos de vista. Primero el de de la Constitución de 1931, en cuyos debates se discutió en profundidad el concepto de autonomía judicial. En segundo lugar, el de la evolución de la definición del concepto en Europa con la clara preferencia en favor de un modelo de consejo judicial de tipo italiano para la articulación de la independencia. En tercer lugar, se estudia la crítica a ese modelo tanto teórica como práctica. En cuarto lugar, y de manera conclusiva, se propone un punto de vista que identifique los elementos mínimos del autogobierno judicial para garantizar la independencia del poder judicial sin eliminar la legitimación democrática que éste ha de mantener.

Zbog kvalitete nutritivnoga sastava, pšenična se trava (Triticum aestivum L.) smatra funkcionalnom hranom te postaje sve popularnija kao dodatak svakodnevnoj prehrani ljudi. Cilj istraživanja bio je utvrditi utjecaj broja otkosa i sorte na ukupnu antioksidativnu aktivnost (DPPH), sadržaj kloroplastnih pigmenata, vitamina C, fenola i flavonoida. U pokusu su ispitana dva genotipa pšenične trave, Triticum aestivum ssp. aestivum (kultivar Katarina) i Triticum aestivum ssp. sphaerococcum. U obama otkosima utvrđen je značajan utjecaj genotipa na sadržaj flavonoida i antioksidacijsku aktivnost, dok je broj otkosa značajno utjecao na fenole, vitamin C i antioksidacijsku aktivnost. T. sphaerococcum imao je veću koncentraciju flavonoida i značajno nižu antioksidativnu aktivnost u usporedbi s kultivarom Katarina. U prosjeku je za obje sorte u prvome otkosu utvrđen značajno veći sadržaj fenola i veći sadržaj vitamina C, što je bilo popraćeno i većom antioksidativnom aktivnošću. Kod kultivara Katarina značajno veći sadržaj fenola i antioksidativna aktivnost utvrđeni su u prvome otkosu. Kod T. sphaerococcum utvđen je značajan pad sadržaja ispitivanih antioksidanasa u drugome otkosu.

Mobile technologies have emerged as a new business phenomenon as a result of the increasing popularity of mobile devices and the proliferation of mobile technologies. A number of marketing research studies have focused on the identification of the background and consequences of mobile commerce, thus enabling m-commerce service providers to design appropriate marketing strategies. This paper’s major contributions are the importance of trust in adopting mobile payments under the influence of perceived risk and structural assurance, as well as the identification of business-related factors that affect mobile trust. A quantitative study was carried out, with 175 valid auto-administered questionnaires collected and analysed using structural equations modelling. The analysis results indicate the positive effect of perceived risk and structural assurance in mobile trust on mobile payment adoption intention. It is important to raise managers’ awareness of preserving the security of services in order to develop mobile trust. Also, to reduce the perceived risk associated with mobile financial transactions, managers need to provide basic insurance for customers in order to defend their transactions in the event of fraud or a particular problem.
