Catatonic schizophrenia: historical error of psychiatric taxonomy?
Authors: Sivolap Yury P. , Portnova Anna A.
Published: January 2022

Numerous clinical observations and studies of recent decades allow us to question the existence of a catatonic form of schizophrenia or, in any case, the legitimacy of the unconditional attribution of all cases of catatonia to schizophrenia. Antipsychotics used in the treatment of schizophrenia are often ineffective in patients with catatonia, can worsen its manifestations and increase the risk of malignant neuroleptic syndrome. The first-line drugs in the treatment of catatonia are lorazepam and other benzodiazepines, and electroconvulsive therapy is used in case of their ineffectiveness. The concept of the independence of catatonia as a separate neuropsychiatric disease requiring the special therapeutic approaches that do not coincide with traditional treatment of schizophrenia deserves attention.

Authors: Musdalifah Farisha Sestri , Rahmawati Annisa
Published: January 2022

Kebijakan WFH (Work From Home) dan SFH (School From Home) yang diberlakukan oleh pemerintah Indonesia selama masa pandemi membuat beban ganda yang dijalankan oleh dosen perempuan semakin berat. Sebagai seorang ibu, dosen perempuan kini memiliki kewajiban baru untuk mengawasi dan membimbing anak-anaknya selama sekolah daring. Beban ganda yang makin berat di masa pandemi ini dapat berkurang jika akademisi perempuan memiliki pola komunikasi keluarga yang baik. Penelitian ini merupakan studi fenomenologi yang membahas pengalaman komunikasi keluarga pada akademisi perempuan dalam menghadapi beban ganda selama pandemi Covid-19. Komunikasi keluarga dianalisis berdasarkan enam dimensi, yaitu listening skill, speaking skill, self-disclosure, clarity, continuity tracking, dan respect or regard. Wawancara mendalam dilakukan kepada tiga akademisi perempuan untuk mendapatkan pengalaman mereka menjalani beban ganda di masa pandemi dan bagaimana komunikasi keluarga turut berperan di tengah situasi tersebut. Hasil penelitian menunjukkan bahwa tiga informan akademisi perempuan dalam penelitian ini memiliki pemaknaan yang berbeda-beda mengenai beban ganda yang mereka jalani. Berdasarkan enam dimensi komunikasi keluarga, tiga informan dalam penelitian memiliki komunikasi keluarga yang baik sehingga keluarga mampu memberikan kekuatan tersendiri dan mendukung akademisi perempuan dalam menjalankan beban gandanya di masa pandemi Covid-19.The implementation of theWork From Home and School From Home policies imposed by the Indonesian government during the pandemic have made the double burden of female academic lecturers even havier. As a mother, female academic lecturers now have a new obligation to supervise and guide their children during online school. The double burden that is getting havier during this pandemic can be reduced if female academics have good family communication patterns. This research is a phenomenological study that discusses the experience of family communication in female academics facing a double burden during the Covid-19 pandemic. Family communication was analyzed based on six dimensions: listening skills, speaking skills, self-disclosure, clarity, continuity tracking, and respect or regard. In-depth interviews were conducted with three female academics to gain their experience of undergoing a double burden during a pandemic and how family communication plays a role during this situation. The results showed that this study's three female academic informants had different meanings about the double burden as an academician and as a mother. Based on the six dimensions of family communication, the three informants in the study had good family communication. The family provided its own strength and supported female academics in carrying out their double burden during the Covid-19 pandemic

Published: January 2022

Background: While much of the literature has focused on examining barriers to substance use disorders (SUD) treatment with individuals with SUD, there is a dearth of research from the perspective of treatment providers and law enforcement, 2 groups who witness the challenges for addressing SUD. Methods: Using content analysis, this qualitative study explored the perspectives of individuals with SUD, treatment providers, and law enforcement on recommendations about SUD treatment and prevention. Data from 12 focus groups with individuals with SUD were analyzed and triangulated with interviews from treatment providers and law enforcement. Cross case analysis was utilized to identify common categories. Results: The categories identified included education, judicial system, psychosocial barriers, resources, stigma, stages of change, and treatment. Results indicated all groups had similar ideas on how to address SUD. Participants provided recommendations in each category for addressing SUD. Conclusion: Individuals with SUD, treatment providers, and law enforcement officers are affected by complex issues of SUD on micro, mezzo, and macro levels. Public health professionals can help to facilitate changes by advocating for prevention and intervention methods to be implemented to address SUD.

Authors: Jacobson Michael D. , Wilson Josephine , Squibb Anna , Kellar Lisa Collier
Published: January 2022

Background: Numerous investigators have highlighted the need to integrate opioid use disorder (OUD) treatment with maternity care. Since data first became available in 2014, Montgomery County (Ohio) has experienced the highest rates of OUD and unintended opioid overdose deaths in the state. This paper examines the demographics and costs of medical treatment for pregnant women with OUD and their newborns with prenatal exposure to opioids (PEO). Methods: The study involved a retrospective records review of all newborns born between May 1, 2016, and April 30, 2017, at a large, urban medical center. Newborns with PEO were matched with a control group by mother's type of insurance, race/ethnicity, method of birth, and maternal parity. Results: Establishing which of the pregnant women should be diagnosed with OUD and be included in the study group was inordinately challenging. Ultimately, of the 3841 infants birthed during the study period, 131 (3.4%) were iden-tified as being born to mothers with OUD. Significantly more mothers with OUD were White and on Medicaid. Only 25 (19.2%) mothers with OUD engaged in treatment for substance use. Compared to the control group, newborns with PEO were much more likely (71.4% versus 25.4%) to be admitted to the NICU and had much longer lengths of stay in both the NICU (mean of 14.4 versus 4.1 days) and hospital (16.9 versus 5.8 days), resulting in dramatic increases in health care cost. Conclusion: These data underscore the need for a comprehensive, systematic approach to OUD and PEO and affirm the government as a major stakeholder in the care of infants born to these women.

Published: January 2022

Neurogenic myocardial injury occurs as a result of dysregulation of autonomic nervous system. The aim of this study was to explore the frequency of elevated troponin and dynamic ST segment/T wave changes and their relation with left ventricular (LV) systolic functions in acute ischemic stroke patients. One hundred and twenty-five patients (mean age: 65.1±15.2years, 76 male) presenting with acute ischemic stroke were consecutively included. 12-lead electrocardiogram was taken to assess dynamic ST segment/T wave changes, conventional transthoracic echocardiography to determine LV ejection fraction (LVEF). High-sensitive cardiac troponin I (hs-cTnI) level>0.04ng/mL was accepted as elevated. Twenty-seven patients (21.6%) had elevated hs-cTnI and 60 patients (48%) had dynamic ST segment/T wave changes. The stroke patients with elevated hs-cTnI had significantly higher NT-proBNP values (2302±3450pg/mL vs 799±2075pg/mL p<0.001) and higher frequency of ST segment/T wave changes (85.2% vs 37.8% p<0.001), and lower LVEF (52.2±13.6% vs 61.0±8.5% p=0.002) compared to patients with normal troponin levels. The patients with ST segment/T wave changes had significantly higher frequencies of hyper­lipidemia (31.7% vs 15.4% p=0.031) and coronary artery disease (CAD) (43.3% vs 13.8% p<0.001), hs-cTnI (0.19±0.55ng/mL vs 0.02±0.01ng/mL p<0.001) and NT-proBNP levels (1430±2564pg/mL vs 842±2425pg/mL p=0.016), and lower LVEF (56.1±11.7% vs 61.9±8.3% p=0.009). Linear regression analysis revealed presence of CAD, but not ST segment/T wave changes as an independent predictor of hs-cTnI (p=0.034). LVEF was independently associated with hs-cTnI (p=0.003) and presence of CAD (p=0.009) when adjusted by age, sex and presence of ST segment/T wave changes. Troponin elevation and ST segment/T wave changes occurring in patients suffering acute ischemic stroke, especially in those with CAD, may be a sign of neurogenic stunned myocardium.

Published: January 2022

Parkinson’s disease is a progressive neurodegenerative disease characterized by motor and non-motor symptoms. Levodopa is the most effective drug in the symptomatic treatment of the disease. Dopamine receptor agonists provide sustained dopamin-ergic stimulation and have been found to delay the initiation of levodopa treatment and reduce the frequency of various motor complications due to the long-term use of levodopa. The primary aim of this study was to compare the efficacy of potent nonergoline dopamine agonists pramipexole and ropinirole in both “dopamine agonist monotherapy group” and “levodopa add-on therapy group” in Parkinson’s disease. The secondary aims were to evaluate the effects of these agents on depression and the safety of pramipexole and ropinirole. A total of 44 patients aged between 36 and 80 years who were presented to the neurology clinic at Ministry of Health Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkey and were diagnosed with idiopathic Parkinson’s disease, were included into this randomized parallel-group clinical study. Dopamine agonist monotherapy and levodopa add-on therapy patients were randomized into two groups to receive either pramipexole or ropinirole. The maximum daily dosages of pramipexole and ropinirole were 4.5 mg and 24 mg respectively. Patients were followed for 6 months and changes on Unified Parkinson’s Disease Rating Scale, Clinical Global Impression-severity of illness, Clinical Global Impression-improvement, Beck Depression Inven­tory scores, and additionally in advanced stages, changes in levodopa dosages were evaluated. Drug associated side effects were noted and compared. In dopamine agonist monotherapy group all of the subsections and total scores of Unified Parkinson’s Disease Rating Scale and Clinical Global Impression-severity of illness of the pramipexole subgroup showed significant improvement particularly at the end of the sixth month. In the pramipexole subgroup of levodopa add-on therapy group, there were significant improvements on Clinical Global Impression-severity of illness and Beck Depression Inventory scores, but we found significant improvement on Clinical Global Impression-severity of illness score at the end of the sixth month in ropinirole subgroup too. The efficacy of pramipexole and ropinirole as antiparkinsonian drugs for monotherapy and levodopa add-on therapy in Parkinson’s disease and their effects on motor complications when used with levodopa treatment for add-on therapy have been demonstrated in several previous studies. This study supports the effectiveness and safety of pramipexole and ropinirole in the monotherapy and levodopa add-on therapy in the treatment of Parkinson’s disease.

A gerincdaganatok en bloc eltávolítása szükséges primer gerincdaganatok, illetve metasztázisok válogatott eseteiben, amikor az alapbetegség jó prognózisú, onkológiailag jól kontrollált. Három esetet mutatunk be, amelyekben az en bloc reszekciót O-arm asszisztált navigációval vagy minimálisan invazív ventralis feltárással végeztük. O-arm navigáció segítségével végzett osteotomiákkal, az ép csigolyarészek megkímélésével egy emlődaganatos beteg szoliter Th.V. metasztázisát távolítottuk el en bloc. Egy chordomás (L.IV.) és egy carcinoid tumoros (L.V.) betegnél kétoldali minimálisan invazív retroperitonealis feltárásból corpectomiát végeztünk mikroszkóp segítségével. Az emlődaganatos betegnél morbiditás nem következett be, 1 évvel a műtét után lokális recidíva nem ábrázolódott, azonban több csigolyában is metasztázisok jelentek meg az aktív onkológiai kezelés ellenére. Az L.IV. chordomás betegnél a műtét után morbiditást tapasztaltunk, bal alsó végtagi paresis, járásnehezítettség jelentkezett. Másfél évvel a műtét után lokális recidíva nem ábrázolódott. A csak ventralis feltárásnak köszönhetően a gerinc dorsalis, ép struktúráit meg tudtuk őrizni. A carcinoid tumoros beteg esetében morbiditást nem tapasztaltunk. A kontrollvizsgálatokkal lokális recidíva 1 évvel a műtét után nem ábrázolódott. Mind az O-arm navigáció, mind a minimálisan invazív elülső gerincfeltárások segíthetnek a sebészi morbiditás csökkentésében és az ép, nem daganatos gerincstruktúrák megőrzésében. Ez utóbbi fontos szerepet játszhat a gerinc hosszú távú stabilitásának biztosításában. Az új módszerek alkalmazása csak akkor fogadható el, ha onkológiai szempontból, hosszú távon, legalább azonos eredményt tudnak elérni a hagyományos megközelítésekhez képest.

Published: January 2022

Control of HIV/AIDS infection can be done by screening at-risk groups in the social environment to prevent transmission. This study aims to determine the social environment of friends, family, and society’s influence on HIV/AIDS incidence. The study was conducted in December 2020–January 2021 at six Bandar Lampung health centers. The 111 respondents were divided into case/reactive and control/non-reactive groups, with a 1:2 ratio (37:74). Data were obtained by interview. The independent variables were the social environment of friends, family, and community, while the dependent variable was HIV/AIDS incidence. The data were analyzed bivariate and multivariate with the Binary Logistics Regression test utilizing Minitab 16 application, with CI 90% and α 0.1 significance level. The results showed that friends with HIV’s social environment had p 0.087; friend's education p 0.542; risky behavior from friends p 0.853; friends with risky behavior p 0,172; HIV family social environment p 0.999; family education p 0.999; risky behavior from family p 0.998; families with risky behavior p 0.999; HIV community social environment p 0.999; public education p 0.330; risk behavior from the community p 0.690; community with risky behavior p 0.862. Thus, only friends with HIV’s social environment affected HIV/AIDS incidence. Furthermore, having friends with HIV’s social environment will increase the risk of getting HIV/AIDS.
Peran Tata kelola perusahaan pada Pengaruh Utang dan Profitabilitas terhadap Penghindaran Pajak
Authors: Kartikasari Dessy , Kresnawati Etik
Published: January 2022

Latar Belakang: Masih banyak kasus penghindaran pajak (tax avoidance) yang dilakukan oleh perusahaan di Indonesia dengan memanfaatkan kelemahan peraturan perpajakan. Walaupun praktik penghindaran pajak bukan tindakan yang illegal, tetapi dapat mengurangi pendapatan negara.Tujuan: Penelitian ini bertujuan untuk menguji pengaruh utang dan profitabilitas terhadap penghindaran pajak yang dimoderasi dengan tata kelola perusahaan.Metode Penelitian: Penelitian ini adalah pengujian data panel dari 44 perusahaan (132 sampel observasi) yang terdaftar di Bursa Efek Indonesia pada tahun 2018-2020. Sampel ditentukan dengan metode penyampelan bersasaran (purposive sampling). Data dianalisis dengan metode regresi data panel.Hasil Penelitian:Hasil pengujian menunjukkan bahwa utang tidak berpengaruh terhadap penghindaran pajak, sedangkan profitabilitas berpengaruh negative terhadap penghindaran pajak. Tata kelola perusahaan yang diprosi dengan rasio komisaris independen juga tidak memoderasi pengaruh kedua variabel independent terhadap variabel dependen.Keterbatasan Penelitian:Sampel awal yang tidak digunakan dalam penelitian ini relative besar. Hal ini boleh jadi karena pada tahun 2019 dan 2020 kondisi perekonomian dunia sedang terpuruk sehingga banyak sampel tidak memenuhi kriteria yang ditetapkan. Selain itu, rasio dewan komisaris independen sebagai proksi tata kelola perusahaan tidak cukup bervariasi karena perusahaan boleh jadi hanya sekedar memenuhi syarat rasio yang ditetapkan dalam peraturan perundang-undangan.Keaslian/Novetly Penelitian:Penelitian ini adalah replikasi dari penelitian sebelumnya yang diuji kembali pada perusahaan manufaktur dengan menggunakan data panel.
Analysis of Agricultural Policies in Jamaica (2015-2019)
Authors: Gachot Sebastien , De Salvo Carmine Paolo , Rondinone Gonzalo
Published: January 2022

The agricultural sector plays a crucial role in Jamaicas economic development by contributing to employment (15.93% of the active population in 2019; higher than the regional average) and exports (18% of total exports in 2019). This monograph offers an update of the Producer Support Estimate (PSE) methodology applied to Jamaica for the period 2015-2019 and documents the evolution of agricultural policies-related GHG emissions over the same period. Between 2015 and 2019, the market price support remained, by far, the main PSE component in Jamaica, heavily concentrated in the poultry subsector, followed by sugar. The positive trend in non-distorting General Service Support Estimate (GSSE) observed between 2012 and 2014 came to a halt. %GSSE even slightly decreased between 2015 and 2019, making Jamaica lag even further behind other countries. Concerning the GHG emissions, the picture has not changed significantly either. The poultry and sugar subsectors remained those that received most policy support and those that emitted the most. Several policy recommendations arise from this report, such as a shift away from an over-reliance of policy support on MPS and an increased focus on less-distortive forms of support, such as GSSE. Additional R&D investments, physical infrastructures, climate risk management systems would help address some of the agricultural sectors most pressing productivity and profitability issues. Lastly, it is advisable to diversify and rebalance the support provided by agricultural policies across subsectors to better align agricultural policy goals with GHG emissions reduction objective.

Published: January 2022

The objectives of this study were to: (i) explore the psychological well-being of part-time working students at the State University of Malang; (ii) examine the life attitude of these students; (iii) investigate their spiritual health; and (iv) determine whether life attitude and spiritual health can be used to predict psychological well-being of part-time working students at the State University of Malang. This was a quantitative study, which used a descriptive design and was conducted with 85 students recruited through purposive sampling. The instruments used included a psychological well-being scale, life attitude scale, and spiritual health scale. Data were analyzed descriptively, and inferential analysis was carried out using Product Moment. The findings indicated that there was an impact between the three variables. Thus, the results showed that: (i) most of the students had moderate psychological well-being, life attitude and spiritual health; and (ii) there was a significant association between psychological well-being and spiritual health (p = 0.035), but not between psychological well-being and life attitude (p = 0.726). The results suggest that, for a student with a part-time job to have good psychological well-being, they need to enhance their positive life attitude and positive spiritual health.

Analysis of Emotional Suppression and Marital Distress in the First Five Years of Marriage
Authors: Syifa Fadhillah Tiara , Ratnasari Yudiana
Published: January 2022

Emotional suppression is an emotion regulation strategy that is often used in Eastern or Asian cultures like in Indonesia. Emotional suppression can be related to various outcomes in marital relationships such as marital distress. This research explored the association between emotional suppression and marital distress in individuals during their first five years of marriage. 1770 married participants from various regions in Indonesia participated (mean marriage length = 23.49 months). The research variables were measured using the Emotional Regulation Questionnaire (ERQ) and the Revised Dyadic Adjustment Scale (RDAS). Emotional suppression and marital distress were found to be negatively correlated. Differences in the norms in various situations across the culture seemed to influence the result. Inferential statistics were calculated to determine whether there was a significant difference in individual marital distress levels based on gender, the number of children, residential status, and changes in sexual activity during the Covid-19 pandemic.
Keywords: marital distress, emotional suppression, early marriage, Covid-19 pandemic
The Role of the Bystander Effect on Body Shaming Intensity in Psychology Students in Malang City
Authors: Yusri Maulani Safira , Widyatno Aryudho , Hitipeuw Imanuel , Tri Harsono Yudi
Published: January 2022

Body shaming is when the form of one’s body is criticized, either intentionally or not. Body shaming is considered a form of verbal bullying. In body shaming situations, there are actors, victims, and bystanders. A bystander can be an amplifier for the actors to keep carrying out the body shaming. This is called the bystander effect and it occurs when bystanders keep silent and do not support the victim of the body shaming. Body shaming is found commonly on university campuses. Psychology students are no exception, even though they are assumed to possess sensitivity and understanding of body shaming. This study aimed to examine the role of the bystander effect on the intensity of body shaming. A quantitative descriptive correlation approach was used and the research instruments employed were the bystander effect scale and the intensity of body shaming scale. 100 psychology students in Malang city participated. Simple linear regression was used to analyze the data. The results indicated that the bystander effect played a significant role in the intensity of body shaming. The contribution of the bystander effect variable to the body shaming intensity variable was 5.3%.

Evaluating the transnationalisation potential of the economies in the countries of South-Eastern Europe
Authors: Sozinova Eugenia , Oriekhova Tetyana
Published: January 2022

The paper presents an integrated indicator of the potential for transnationalisation, which is the average of five standardised variables that characterise the degree of resource potential for internationalisation in the form of transnational development trade, as well as the algorithm of application of these indicators in order to rank countries according to the degree of development and usage of their existing potential. The analysis makes it possible to state that the level of the actual inflow of FDI to Montenegro is higher than the level of its potential for transnationalisation. The evidence of FDI inflows relative to GDP makes it possible to classify Albania as the leader in transnational business. Evidence of FDI inflows to Bosnia and Herzegovina confirms its characteristics of the transnationalisation potential as an “outsider” to transnationalisation. All other studied countries fell into the category of countries with underestimated investment potential in attracting foreign direct investment, i.e. the potential for transnationalisation (domestic).

Кулешова // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2022. – Т. 333. – № 1. – С.200-213.

Актуальность исследования обусловлена длительным воздействием на объекты окружающей среды (в частности почвы) площадок геологоразведочных скважин, пробуренных в 80–90-х гг. XX в. на территории континентальной части российской Арктики. Устойчивость загрязнения обусловлена прежде всего низкой способностью северных экосистем к самоочищению. Оценка экологической опасности загрязненных грунтов и производственно-хозяйственных отходов на примере Ростовцевского месторождения позволит рассмотреть возможность реализации мер по восстановлению компонентов экосистемы. Цель работы заключается в оценке современного состояния почвенного покрова на Ростовцевском месторождении углеводородов. Объект: территория в районе 25 скважин Ростовцевского месторождения углеводородов (полуостров Ямал, ЯНАО), пробуренных в период с 1986 по 1989 гг. Методы. Комплекс исследований включал отбор и лабораторный анализ 103 проб фоновых и загрязненных почв из верхнего (0–10 см) и нижнего (10–20 см) горизонтов. Особое внимание уделялось изучению анионно-катионного состава, содержания металлов, нефтепродуктов, фенолов, анионных поверхностно-активных веществ. Результаты. Установлен факт прямого загрязнения почв нефтепродуктами, сульфатом бария, цинком, свинцом и другими металлами. Кроме этого, антропогенное воздействие привело к подавлению естественных неоднородностей геохимического поля и формированию однородной приповерхностной физико-химической обстановки. В пределах почвенного слоя отмечается перераспределение соединений и элементов, содержание которых либо не изменилось (анионные поверхностно-активные вещества, мышьяк), либо заметно снизилось (хлорид-ион, обменный аммоний). По суммарному показателю загрязнения вблизи 23 из 25 исследованных буровых площадок содержание вредных веществ охарактеризовано как чрезвычайно опасное. Основной вклад в суммарный показатель загрязнения вносят нефтепродукты.

The relevance. Air pollution due to the activities of the mining and metallurgical industries is a serious problem for the environment. This study was conducted to determine the possible mechanisms of migration and the sources of elements in the atmosphere above the surface of tailings. The main aim of the research is to show that chemical elements can be trapped by the water vapor and can migrate with the vapor phase during the desorption and dehydration of hydrous sulfates. Object: samples from the surface of the Belovo waste heaps (Belovo zinc processing plant, Belovo, Russia). Methods. Powder X-ray diffractometry (XRD) was used to determine the phase compositions of the crystalline substances, their quantitative phase relationships and transformations. An Agilent 8800 ICP-MS instrument (Tokyo, Japan), equipped with a MicroMist nebulizer, was used to determine the elements in the water samples (pore solution and condensates). Also, we used binocular microscope and physicochemical modeling methods. Results. By analyzing the condensates, it was determined that a wide range of chemical elements can migrate with vapor-gas streams from secondary hydrous sulfates under relatively low-temperature conditions (60 °C). Condensate from the wet sample contains high element concentrations due to the input of elements from the pore solution and hydrous sulfates. Alterations in mineral structure and water release are indicated by losses of sample weight. With dehydration, cations and trace elements can be extracted from the crystal lattice, replaced by protons, and can then enter the vapor-gas phase when the solution evaporates.
ИЗОТОПНАЯ ХАРАКТЕРИСТИКА СЕРЫ АРСЕНОПИРИТА ИЗ ЦЕНТРАЛЬНОЙ ЧАСТИ ЗАЛЕЖИ МЕСТОРОЖДЕНИЯ ЧЕРТОВО КОРЫТО (ПАТОМСКОЕ НАГОРЬЕ)

Актуальность. Месторождение Чертово Корыто располагается в пределах Ленской золотоносной провинции, в которой сосредоточенны крупные по запасам месторождения золота (Сухой Лог, Вернинское, Высочайшее, Ожерелье и др.). Изучению этой провинции уделено много внимания, что отражено в огромном числе публикаций. Несмотря на это, единое представление о происхождении месторождений золота, образованных в черносланцевых толщах Бодайбинского прогиба, отсутствует. Дискуссионным остается вопрос об источнике полезного компонента и выявлении механизма его транспортировки, перераспределения и концентрирования. Ввиду этого становится актуальным изучение изотопных отношений серы сульфидов для определения возможного источника благородного металла. В месторождении Чертово Корыто изотопные отношения серы сульфидов изучены в ограниченном количестве и не отражают изменения этого параметра на глубину и по простиранию рудной залежи. В силу малоизученности этот объект является интересным для исследований в области изотопной геологии. Цель – выявление возможных источников рудного вещества по результатам изотопных исследований серы арсенопирита. Объектом исследования является арсенопирит из центральной части рудной залежи. Методы. Масспектрометрические измерения с использованием газового масс-спектрометра. Результаты. Исследования показали выдержанность изотопного состава серы арсенопирита (–3,8‰…+4,3 ‰) на глубину, что свидетельствует об однородном источнике серы в период рудообразования. Приближенные при этом к метеоритному стандарту значения указывают на эндогенный источник рудообразующих флюидов.

Актуальность. Равнинная территория Западной Сибири характеризуется очень высокой заболоченностью. Вследствие этого хозяйственная деятельность часто проводится на болотах и заболоченных землях, что определяет необходимость изучения самоочищения болотной среды для снижения негативного антропогенного воздействия на окружающую среду и оптимизации хозяйственной деятельности. Цель: экспериментальное изучение условий распространения в болотной среде загрязняющих веществ и самоочищения евтрофной болотной экосистемы. Методы: полевой эксперимент, методы определения химического состава болотных вод и водных вытяжек из торфов и минеральных отложений, статистические методы. Результаты и выводы. 18 марта 2021 г. на Обском болоте (юг Томской области) в районе с. Нащеково пробурено 5 скважин, отобраны пробы болотных вод в деятельном горизонте торфяной залежи и торфов через 0,25 м. Четыре скважины расположены в виде вершин квадрата со стороной 100 м. В середине квадрата на поверхности болота 19.03.2021 г. выполнен выпуск 50 л раствора NaCl с концентрацией 20 г/дм3. Повторные бурение и отбор проб болотных вод и торфов проведены 16.10.2021 г. Показано, что в течение этого периода непосредственно в месте выпуска раствора NaCl в интервале глубин 1,50–2,00 м сформировались относительно повышенные концентрации Na+ (до 11,5 мг/дм3) и Cl– (до 22,4 мг/дм3). В прочих скважинах (на удалении около 70 м от выпуска) значимые изменения значений рН, удельной электропроводности EC, концентраций Na+ и Cl– в болотных водах и водных вытяжках из торфов, связанные с выпуском раствора NaCl, не выявлены, что свидетельствует о высокой способности болотной экосистемы к самоочищению.

Background: Broccoli is a cruciferous vegetable with green flower buds. It has a reputation as a superfood as it is low in calories but contains a wealth of nutrients and antioxidants that support many aspects of human health. Broccoli is a good source of fibre and protein and contains iron, potassium, calcium, selenium and magnesium as well as the vitamins A, C, E, K and a good array of B vitamins including folic acid. Methods: Thirty days old and uniform seedlings of broccoli cv. Palam Samridhi were transplanted in the field at a spacing of 45 × 45 cm. Different concentrations of Mel, viz. 0, 20, 40, 60 and 80 ppm with three replications were sprayed at 15 days after transplanting (DAT). Head diameter, weight, chlorophyll and carotenoids, sugar, proteins and antioxidant were analyzed at harvest. Result: Results showed that the maximum head diameter (10.7 cm), weight (233.8 g), chlorophyll (0.79 mg/g.FW), carotenoid (0.028 mg/g.FW), phenol (178.1 mg/100 g DW), total antioxidant (362.3 mg GAE 100 g DW) and MSI (45.38%) levels were recorded with Mel 60 ppm. However, the highest levels of sugar (129.0 µg/g) and protein (88.0 µg/g) were recorded with Mel 80 ppm followed by Mel 60 ppm.

The paper considers an approach to justification of parameters for a cylindrical part of a tank shell in terms of construction stability loss at influence of external excessive pressure. A feature of the proposed approach is in the fact that it considers a level of filling of a tank shell with a liquid freight. The considered approach is based on a differential equation of gently sloping cylindrical shell. The authors use radial loads that are conditioned by external excessive and internal hydrostatic pressure as applied external forces. The differential equation is solved by the Bubnov - Galerkin method with the use of double trigonometric series. As a result, the authors have gained an algebraic expression that allows determining a level of critical excessive external pressure that can influence on tank shell at freight discharge, in case of failure of pressure relief valves, after flush and steam-curing and premature closure of tank hatches. On the basis of the algebraic expression the authors have determined values of critical pressure at various levels of filling with liquid freight for different types of railway tank-cars. Moreover, they have compared results of the study with data calculated with the use of the finite element method.

Published: January 2022

The paper considers a damping layer design for roadbed with parameters that provide safety of railway traffic in seismically dangerous regions. It presents a theoretical study of seismic forces on railway roadbed on the basis of analysis of earthquake influence parameters on stressed and strained state of railway track construction. For the investigations the author has applied methods of multifactorial experimental design. The author has developed a method for determination of optimal parameters for damping depending on main parameters of an earthquake (magnitude, distance from hypocenter, physical and mechanical characteristics of the Earth crust) and geological characteristics of a railway section (capability of layers, deformational and elastic properties of the Earth crust, foundation and roadbed). As a result, the author suggests designs of a damping layer that has a layered-geterogenous compositional structure with given properties. Moreover, he has established a possibility to increase an aseismic stability of railway roadbed by construction of the damping layer with given properties.

In modern automobiles operational control of work processes of internal combustion engines is executed by an electronic engine control system (EECS) in which operational damage inevitably arises due to influence of mechanical, chemical and other processes. In order to detect and localize the damage the authors suggest a method for determination of the EECS condition with a preliminary assessment of its no-failure probability P(t) that allows establishing a possibility of a system failure according to operating time up to next scheduled automobile maintenance. A value of the P(t) indicator depends on condition of the EECS structural elements and is determined by corresponding diagnostic parameters. As a result, the authors suggest a regression equation that allows assessing influence of values of diagnostic parameters on an optimization parameter and the solution of which is conducted with the use of the experimental design method. In order to simplify calculations the authors have developed a computer program that gives a possibility to determine the probability of the EECS no-failure operation and its life according to diagnostic parameters gained at scheduled maintenance.

Improvisation, Identity and Systems from outside
Authors: Carvalho Frederico Lyra de
Published: January 2022

In this article we propose to analyse some aspects of the music and musical thought of the musician Steve Coleman through the philosophy of Theodor Adorno. We will deal with Coleman's relationship to tradition and the concept of jazz, the practice of improvisation and the systematicality of his music. These questions will be treated under the prism of the dialectics of identity and non-identity dear to Adorno's Negative Dialectics. The objective is to try to demonstrate some of the contradictions that circumscribe Coleman's work and how it is built through them. We will deal with Coleman's relationship to the jazz tradition, his practice of improvisation and the systematicality of his music.
A teoria crítica da música revisitada
Authors: Silva Ricardo Ribeiro Lira da
Published: January 2022

O artigo propõe retomar certos problemas fundamentais da teoria crítica da música de Adorno a partir de um de seus trabalhos tardios pouco discutidos na literatura secundária: a Introdução à sociologia da músca (1968). Nossa hipótese é a de que o livro fornece uma visão retrospectiva privilegiada dos escritos musicais adornianos, permitindo a reconsideração de categorias teóricas desenvolvidas nos anos 1930 e 1940, relacionadas tanto ao diagnóstico sobre a música popular no âmbito da indústria cultural, quanto ao potencial crítico da música de vanguarda e seus limites. Conforme pretendemos sustentar, tal reconsideração permite afastar interpretações que atribuem à reflexão de Adorno um caráter prescritivo e enrijecido, colocando em evidência que sua teoria crítica da música consiste sobretudo na pergunta pelas condições sociais concretas para uma relação não reificada e não regulamentada com a música.
