Cross-Calibration of an α-Source Used for Luminescence Dating by Applying Different Samples and Procedures
Authors: Sipos György , Schmidt Christoph , Bartyik Tamás , Filyó Dávid , Magyar Gergő , Havasi Viktor , Kukovecz Ákos
Published: June 2021

In terms of fine-grain luminescence dating applications, the efficiency of α-radiation in producing luminescence is an important issue when determining environmental dose rates. Efficiency is usually assessed by measuring the ratio of luminescence intensities induced by known α and β laboratory doses. Consequently, most thermoluminescence (TL)/optically stimulated luminescence (OSL) readers besides the standard 90Sr/90Y β-source can also be equipped with a 241Am α-source. A crucial point is, however, the calibration of these sources. The calibration of β-sources is routinely performed using standard quartz samples previously irradiated by a known γ-dose, though, in the case of α-sources, the procedure is less standardised, partly because there are no calibration materials with a known α-efficiency value.

In this study, we aimed to cross-calibrate the built-in α-source of a RISØ TL/OSL DA-20 luminescence reader by testing and comparing five procedures, applying different samples (quartz and polymineral), different protocols multiple aliquot regeneration (MAR) and single aliquot regeneration (SAR) and different calibration sources. Throughout the tests, the performance of the fine-grain RISØ calibration quartz was also assessed.

Regardless of the applied procedure, the calculated α-dose rates with one exception gave similar results. On the one hand, the applied polymineral sample due to potential fading, fairly high residuals after bleaching and relatively low infrared stimulated luminescence (IRSL) sensitivity proved to be the least optimal choice for cross-calibration. On the other hand, the tested natural fine grain quartz gave almost identical results when using different types of bleaching and different calibration α-sources. The mean dose rate determined for the source was 0.080 ± 0.004 Gy/s.

The cross-calibration by using the RISØ fine grain quartz yielded somewhat higher but at the apparent uncertainty of luminescence dating still not significantly different dose rate for the source under calibration. Tests showed that the calibration quartz saturates at a relatively low α-dose, and the shape of α- and β-dose-response curves also depart from each other quite early, suggesting that cross-calibration with this material seems to be reliable only at low doses. For the first time, the a-value of the fine-grain calibration quartz was also determined using the freshly calibrated α-source, and the measurement yielded a 0.054 ± 0.003 value. We propose that after further validation of this result, the RISØ calibration quartz can ease the dose rate assessment of uncalibrated α-sources in the future.
PERANAN BANGSAWAN BONE DALAM SISTEM PEMERINTAHAN DARI SWAPRAJA KE KABUPATEN (The Role of Bone Nobleman in The Government System from Swapraja to Regency)
Authors: Widiawati Risma
Published: June 2021

Bone Regency as part of South Sulawesi is a very interesting area to discuss. This area is not only part of the history of South Sulawesi, but also a historical flow of South Sulawesi. the existence of nobles who are so attached to the joints of the lives of the people of Bone is still interesting to be examined to this day. Based on this, the article aims to reveal the role of Bone nobility in the swapraja government system to the regency (1950 - 1960). The political development of the government during this period was seen as sufficiently influencing the political dynamics of the government in Bone Regency which continued even today. The method used is the method of historical research with four stages, namely, heuristics, criticism (history), interpretation, and presentation (historiography). The results of the study show that after the transition from swapraja to regency, the role of nobility is still very calculated. But it is no longer like in the period before the transition, where the government was ruled by the king / aristocracy. At this time the level of intelligence is also taken into account. Apart from the fact that the structure of the government is indeed different because the process of appointing head of government is also different. But in general the role of nobility after the transition was not much different, where there were still many nobles holding power. ABSTRAK Kabupaten Bone sebagai bahagian dari Sulawesi Selatan merupakan suatu daerah yang sangat menarik untuk dibicarakan. Daerah ini bukan saja merupakan bagian dari sejarah Sulawesi Selatan, tetapi juga merupakan arus sejarah Sulawesi Selatan. keberadaan bangsawan yang begitu melekat di dalam sendi kehidupan masyarakat Bone masih menarik untuk ditelisik sampai hari ini. Berdasarkan hal tersebut, maka artikel ini bertujuan untuk mengungkapkan tentang peranan bangsawan Bone dalam sistem pemerintahan swapraja ke kabupaten (1950 – 1960). Perkembangan politik dari pemerintahan selama periode ini dipandang cukup mempengaruhi dinamika politik dari pemerintahan di Kabupaten Bone yang berlangsung bahkan sampai sekarang. Metode yang digunakan adalah adalah metode penelitian sejarah dengan empat tahapan yaitu, heuristik, kritik (sejarah), intrepretasi, dan penyajian (historiografi). Hasil penelitian menunjukkan bahwa setelah peralihan dari swapraja ke kabupaten, peranan bangsawan masih sangat diperhitungkan. Namun tidak lagi seperti pada masa sebelum peralihan, di mana pemerintahan dikuasai oleh raja/aristokrasi. Pada masa ini tingkat kecerdasan juga diperhitungkan. Selain karena struktur pemerintahannya memang berbeda juga karena proses pengangkatan kepala pemerintahan juga berbeda. Namun secara umum peran bangsawan setelah masa peralihan tidak jauh berbeda, di mana masih banyak bangsawan yang memegang kekuasaan.

LANDSCAPE AND ORIENTATION OF MEGALITHIC CHAMBERS IN MECKLENBURG-VORPOMMERN (NORTH GERMANY): PHENOMENOLOGY PERSPECTIVE (Bentang Alam dan Orientasi Megalitik di Mecklenburg-Vorpommern Jerman Utara: Perspektif Phenomenologi)
Authors: Tolla Marlin
Published: June 2021

Phenomenological perspective is one of the approaches in archaeology especially applies to the use of sensory experiences of the past peoples through material cultures. Phenomenological approaches is based of some German philosopher such as Edmund Husserl, MartinHeidegger which put their attention to perceptions and knowledge which are based on experience of daily lives. Phenomenological approach have been produces a great impact through some works of archaeologist especialy from the group of Post-Procesualist such as Christian Tilley and others in attempt to interpretated the landscape phenomenon in Britain archaeological sites. In relations with that, the phenomenology approaches will be used to analysed the groups of megaliths chambers in Mecklenburg-Vorpommern (northern Germany) according to the cosmological significance.ABSTRAKPenomenologi adalah salah satu pendekatan yang digunakan dalam arkeolologi terutama dalam menganalisa ‘experience’ atau pengalaman manusia pada masa lalu melalui budaya material yang ditinggalkan. Pendekatan ini diadopsi dari filosof Jerman seperti: Edmund Husserl dan Martin Heidegger yang menekankan bahwa esensi dari presepsi manusia adalah terletak pada ‘pengalaman’ yang ditemukan di setiap hari. Pendekatan ini kemudian diadopsi oleh arkeolog terutama yang berasal dari grup Post-prosesualis seperti Christian Tilley dan lainnya terutama dalam menginterpretasikan arkeologi landskap. Merujuk pada hal ini, megalitik di Mecklenburg-Vorpommern diindikasikan sebagai ‘buah’ dari pengalaman oleh manusia pada masa lalu dalam menginterpretasikan alam sekitar mereka terutama dalam hubungannya dengan kosmologi.

GAMBARAN TINGKAT KEPUTUSASAAN PADA WANITA KORBAN KEKERASAN DALAM RUMAH TANGGA
Authors: Hervika Lia , Satiadarma Monty P. , Soetikno Naomi
Published: June 2021

Kekerasan dalam rumah tangga (KDRT) mendominasi kasus kekerasan terhadap perempuan (KTP) di Indonesia. Beberapa penelitian menunjukkan korban KDRT mengalami dampak psikologis, seperti depresi dan ide bunuh diri. Meskipun memberikan dampak yang negatif, masih terdapat wanita yang menerima dan membenarkan KDRT yang dilakukan oleh suami. Selain itu, banyak juga korban yang memilih untuk keluar dari siklus KDRT. Temuan tersebut menunjukkan respon wanita tampak berbeda terhadap pengalaman KDRT. Keputusasaan merupakan salah satu faktor yang diteliti pada wanita korban KDRT. Wanita korban KDRT yang putus asa cenderung mengalami kesulitan dalam mengambil keputusan, terutama keputusan untuk berpisah dari pelaku kekerasan dan keluar dari siklus kekerasan. Penelitian ini bertujuan mengetahui gambaran tingkat keputusasaan pada 52 wanita yang pernah mengalami kekerasan dalam rumah tangga di Indonesia. Metode penelitian bersifat kuantitatif deskriptif dan data dikumpulkan menggunakan kuesioner Beck Hopelessness Scale (BHS). Hasil menunjukkan 68% partisipan penelitian memiliki keputusasaan pada kategori sedang. Partisipan yang tidak bekerja, berlatar pendidikan SMA/SMK, tidak atau belum memiliki anak, tidak melaporkan, dan tidak memiliki dukungan sosial cenderung memiliki skor keputusasaan yang lebih tinggi. Keterbatasan jumlah partisipan menyebabkan generalisasi hasil penelitian terbatas. Penelitian selanjutnya dapat mengkaji partisipan dengan cakupan wilayah dan latar belakang budaya yang lebih luas. Latar belakang budaya tentu menjadi salah satu faktor yang memengaruhi keputusasaan serta keputusan wanita yang mengalami KDRT untuk berpisah atau tetap berada pada siklus KDRT yang dialami. Violence against women in Indonesia is dominated by domestic violence. During the pandemic situation, the victim may become hampered in reporting the case. Previous studies show that domestic violence might bring psychological impacts to the victim, like depression and suicidal ideation. Hopelessness might affect the response among victims. Previous studies reported that women who experienced domestic violence had moderate to high levels of hopelessness. They tend to show poor decision-making and hard to break the violence cycle. This study aims to describe the level of hopelessness in 51 women who have experienced domestic violence in Indonesia. The research method is descriptive quantitative. Data were collected using Beck Hopelessness Scale (BHS). Results showed 68% of participants have moderate level of hopelessness. Participants with no occupation, high school educational background, not reporting the case, and do not have social support tend to have higher score of hopelessness. This study provides information about levels of hopelessness but the generalization of the result is limited due to the limited participants and cultural background. Further research should describe more number of participants with wider cultural background.

Authors: Perera Fabiana Sofia , Núñez-Argueta Kimberly , Smith Emily F.
Published: June 2021

The adoption of UNSCR 1325 in October 2000 signaled the UN Security Council’s commitment to promoting gender inclusivity in peace and security agendas. Twenty years after it was signed, progress on the Women, Peace and Security Agenda (WPS) goals has been uneven, varying across issue areas and regions. This paper assesses the progress that Latin America has made in the inclusion of women in peacekeeping and evaluates the importance of the adoption of National Action Plans (NAPs) in reaching these goals. It concludes that while NAPs are important towards achieving WPS goals regarding peacekeeping, they are not sufficient.

Authors: A.F. NAHLA , W.Z. BADAWY , M.A. EL-BANA , H.A. KASSAB
Published: June 2021

Quinoa is recently gaining more interest from many countries as a nutritious substitute and food addition. Proximate chemical analysis of quinoa flour (QF) was estimated. Additionally, the rheological properties of balady bread dough fortified with QF were evaluated. It was found that QF was an ideal source of minerals especially potassium (808.7 mg/100 g) and essential amino acids compared with wheat flour. Moreover, the protein content of bread substituted with QF increased by increasing QF content. Also, the sensory properties of bread were acceptable. There was no noticeable difference (P≤ 0.05) between bread fortified with 10% and control sample. The gluten levels went down by raising the levels of QF from 10 to 40% whilst; the protein content increased from 10 to 40% by rising QF replacement levels. The obtained date suggested that QF could be utilized as fortifying source of protein and nutrients especially, in bakery products.

Maize represents a staple food crop and is the second most important agricultural commodity globally. Considering the important role of maize for food security, the long-term conservation of valuable germplasm is critical to ensure that high levels of genetic diversity are available for breeding superior cultivars to face future challenges. Cryopreservation is regarded as the most appropriate tool for long-term germplasm preservation and has been investigated in different crops. This short communication adds to the existing knowledge on maize cryopreservation by describing histological changes observed in maize seeds and young germinating embryos after liquid nitrogen (LN) exposure. Plants were examined immediately after recovery from LN (day zero) and following 3 days of germination. At day 3, seeds exposed to LN showed lower germination rates than non-cryostored seeds, i.e., 60.7% vs. 83.3%. Histological evaluation at day 3 revealed that the thickness of the conical endosperm and the scutellum did not show any statistically significant differences between control and cryopreserved seeds. In contrast, for the other histological evaluations made, mostly regarding the thickness of mesocarp, mealy endosperm, plumule, radicle and the epidermis, significant differences were observed between control and cryostored seeds with the former consistently displaying higher average values than the latter.

Deaths and Injuries from Unintentional Falls: An Analysis of Nepal Police Records
Authors:   Department of Population Studies, Padmakanya Multiple Campus, Kathmandu, Nepal, Sedain Bhagabati
Published: June 2021

Falls are a major cause of unintentional injury-related global mortality and morbidity. The actual mortality and morbidity from falls in Nepal have been overlooked and not systematically studied. This study, therefore, aims to present the national status of fall-related deaths and injuries. The study analyzed the fall incidents recorded by Nepal Police for five fiscal years (17 July 2014 to 16 July 2019). These incident recordings were in the form of narratives, and possible variables were extracted for the analysis. In five years, 4,714 people were injured or died from falls in Nepal. The average age of the fall victim was 35.6 years (SD=19.94); the mean age of the person who died from falls was slightly lower (30.9 years) than the injured person (40.4 years). The analysis showed that the fall cases were remarkably greater for males than females. This study found that Bagmati Province, where the capital city was located has the highest death and injury rates from falls, followed by Gandaki Province and Province 1. The study identified 11 different locations of falls. These findings revealed that Nepal has a considerable burden of fall deaths and injuries. However, the actual burden of fall injuries might be higher due to the under-reporting of the incidents through the Nepal Police data recording system.

Evaluation of 3D printed microfluidic networks to study fluid flow in rocks
Authors: Mousavi Seyed Mahdi , Sadeghnejad Saeid , Ostadhassan Mehdi
Published: June 2021

Visualizing fluid flow in porous media can provide a better understanding of transport phenomena at the pore scale. In this regard, transparent micromodels are suitable tools to investigate fluid flow in porous media. However, using glass as the primary material makes them inappropriate for predicting the natural behavior of rocks. Moreover, constructing these micromodels is time-consuming via conventional methods. Thus, an alternative approach can be to employ 3D printing technology to fabricate representative porous media. This study investigates fluid flow processes through a transparent microfluidic device based on a complex porous geometry (natural rock) using digital-light processing printing technology. Unlike previous studies, this one has focused on manufacturing repeatability. This micromodel, like a custom-built transparent cell, is capable of modeling single and multiphase transport phenomena. First, the tomographic data of a carbonate rock sample is segmented and 3D printed by a digital-light processing printer. Two miscible and immiscible tracer injection experiments are performed on the printed microfluidic media, while the experiments are verified with the same boundary conditions using a CFD simulator. The comparison of the results is based on Structural Similarity Index Measure (SSIM), where in both miscible and immiscible experiments, more than 80% SSIM is achieved. This confirms the reliability of printing methodology for manufacturing reusable microfluidic models as a promising and reliable tool for visual investigation of fluid flow in porous media. Ultimately, this study presents a novel comprehensive framework for manufacturing 2.5D realistic microfluidic devices (micromodels) from pore-scale rock images that are validated through CFD simulations.
Incidence of pancreatic malignancies in the Russian Federation: a retrospective cohort trial
Authors: Moiseenko V. E. , Pavlovsky A. V. , Granov D. A. , Kardanova I. G. , Kochorova L. V. , Dodonova I. V.
Published: June 2021

Background. Pancreatic malignancies pose a challenging medical and social problem. The assessment of oncology care requires an in-depth analysis of morbidity and lethality. At a relatively improved prevalence and lethality in other-locale malignancies, pancreatic cancer remains a disappointing situation. Medical statistics in pancreatic malignancy can be used for the specialty care prediction and implementation of measures to advance diagnostic algorithms and population screening.

Objectives. An assessment of the pancreatic malignancy incidence and mortality in the adult population of Russian Federation over a six-year period.

Methods. A retrospective descriptive cohort trial included statistical data on morbidity and mortality in pancreatic cancer patients (C 25.0-C 25.9) according to the ICD of 10th edition. A comparison cohort sampled patients with all-locale neoplasms (C00-C96) according to the ICD of 10th edition, excluding nosologies C25.0-C25.9. Information was sourced in the Federal Statistical Abstracts for the period of 2014-2019. Inclusion criteria: the study cohort included pancreatic cancer patients diagnosed at the age of 18 years on, and comparison cohort — malignancy patients diagnosed with at 18 years on. The main study indicator were the pancreatic cancer morbidity and mortality figures in Russia.

Results. Pancreatic cancer was shown to co-increase main morbidity figures in 2014-2019 compared to malignant neoplasms of other localities. Other-locale malignancies decreased mortality over the study period, which was not the case with pancreatic cancer. The period exhibits more frequent morphologically verified diagnoses and higher population numbers registered with specialty dispensaries. Registered pancreatic cancer figures are significantly higher in the female population. The proportion of advanced pancreatic malignancies at primary diagnosis exceeds that of early stages.

Conclusion. The findings expose a demand for improving the system of early pancreatic cancer detection via intensifying preventive measures to capture the patient’s predisposition and screening techniques for early disease diagnosis. An active outpatient surveillance is prerequisite to an effective population involvement in dispensary screening.

Results. 3 months after the modeling of experimental chronic tonsillitis, dystrophic changes in the layer of nerve fibers, RPE dysfunction, and a reduced thickness of the own choroid persist. There is a deterioration in the functional state of the microcirculatory bed in the equatorial part of the eye. Conclusion. The use of optical coherence tomography, along with laser Doppler flowmetry, seems to be promising in assessing chorioretinal changes after modeling chronic tonsillitis. In the long term, after modeling of chronic tonsillitis, dystrophic changes in the layer of nerve fibers, hyperplasia of RPE cells, and a decrease in the thickness of its own choroid persist. There is a deterioration in the functional state of the microcirculatory bed in the equatorial part of the eye.

Исследовано геометрическая оптимизация, упругие модули суперячеек Ca24Si22O52(OH)16Wt28с 28 молекулами воды, внедренными под разными углами. Внедрение на контролируемый угол осуществлялось операциями вращения вокруг осей ОX, ОY, ОZ молекул воды. Исследования показали, что ориентировка молекул H2O оказывает заметное влияние на внутреннюю энергию, упругие модули и стабильность оптимизированной суперячейки, а также геометрические параметры решетки. Было установлено, что суперячейки с H2O внедренными под углами α: 2°, 4°, 20°, 80°, 300°, 354° и 356° относятся к стабильным конфигурациям, а суперячейка с H2O, α=20° оказывается наиболее стабильной. В работе для геометрически оптимизированных состояний определены уточненные параметры структур, объем решеток, упругие модули и координаты атомов. Стабильные суперячейки решетки могут быть включены в базу Ричардсона с целью применения в качестве эталона при анализе методом Ритвельда структурных свойств гидратированных портландцементов.

Приводятся данные влияния концентрации окиси меди, вводимой в композиционные гранулы на основе обезвоженной боной кислоты на структуру и микротвердость боридных покрытий. На основании проведенных исследований установлено, что введение окиси меди непосредственно в состав гранулы и ее количество оказывает влияние на характеристики боридных покрытий в структурном соотношении боридных слоев с искомым получением однофазного покрытия из низшего борида железа. По изученному концентрационному влиянию окиси меди на структуру боридных покрытий также определяется влияние содержания углерода в обрабатываемой стали, при увеличении которого происходит выраженная трансформация боридного слоя с потерей игольчатой структуры. Определена отптимальная концентрация окиси меди в грануле для обеспечения распределения микротвердости боридного покрытия с увеличением к середине слоя, что является более благоприятной для повышения износостойкости пар трения скольжения. Приводится состав для боромеднения.

Целью настоящей работы являлся анализ структуры и свойств покрытия состава Ni-C-Ag-N, сформированного на меди комплексным методом, сочетающим электровзрывное напыление покрытия состава Ni-C-Ag, облучение его импульсным электронным пучком и последующее азотирование в плазме газового разряда низкого давления. Показано, что толщина покрытия составляет ≈ 90 мкм. Износостойкость медного образца с нанесенным покрытием превышает износостойкость меди без покрытия в ≈ 1,6 раза. Коэффициент трения образцов с покрытием (μ = 0,5) меньше коэффициента трения меди без покрытия (μ = 0,679) в ≈ 1,35 раза. Установлено, что твердость покрытия увеличивается по мере приближения к подложке и достигает максимального значения ≈ 1780 МПа (твердость подложки 1300 МПа). Методами микрорентгеноспектрального анализа установлено, что основным химическим элементом покрытия является серебро, в значительно меньшем количестве присутствуют медь, никель, углерод и азот. Методами дифракционной электронной микроскопии установлено, что основными фазами покрытия являются твердые растворы на основе меди и серебра, выявлены включения нитридов и карбонитридов серебра нанометрового диапазона. Ранее авторами настоящей статьи были получены покрытия системы Ni-Ag-N, которые были сформированы при тех же режимных параметрах, но без использования углеграфитового волокна. Введение углеграфитового волокна позволяет добиться большей износостойкости и более низкого коэффициента трения. В совокупности структурных составляющих, значений износостойкости и твердости покрытие состава Ni-C-Ag-N имеет лучшие перспективы использования в реальном секторе экономики.
ВЛИЯНИЕ ХИМИЧЕСКОГО СОСТАВА СТАЛИ НА СТРУКТУРУ И СВОЙСТВА ДИФФУЗИОННЫХ ПОКРЫТИЙ, ПОЛУЧЕННЫХ ОДНОВРЕМЕННЫМ НАСЫЩЕНИЕМ БОРОМ, ХРОМОМ И ТИТАНОМ КОНСТРУКЦИОННЫХ СТАЛЕЙ

В работе представлен сравнительный анализ микроструктуры диффузионных покрытий на сталях 45 и 38Х2МЮА, полученных одновременным диффузионным насыщением бором, хромом и титаном. Насыщение производили путем упаковки насыщаемых образцов размерами 15х15х50 мм в жаростойкий контейнер с порошковой насыщающей средой. При насыщении стали 45, толщина диффузионного слоя составляет 120-140 мкм, тогда как при насыщении стали 38Х2МЮА, толщина диффузионного покрытия находится в пределах 70-80 мкм, что на 58 % меньше. Переходная зона образца из стали 38Х2МЮА содержит до 20 об. % феррита, тогда как в случае стали 45 переходная зона представлена только перлитом. Максимальная микротвердость диффузионного слоя на стали 38Х2МЮА в 1,8 раза уступает показателю максимальной микротвердости диффузионного слоя на стали 45. При этом поверхностная микротвердость на обеих сталях практически одинакова и находится в районе 1500 HV0,1. Микротвердость переходной зоны в случае стали 45 выше, чем в случае стали 38Х2МЮА по причине практически полного отсутствия ферритной фазы. По данным дюрометрического анализа, толщина диффузионного слоя на стали 38Х2МЮА не превышает 85 мкм, толщина диффузионного слоя на стали 45 составляет 120 мкм, что коррелирует с результатами металлографического анализа. Упрочненные комплексным бор-хром-титанированием детали из стали 38Х2МЮА, обладая более низкой поверхностной твердостью, чем детали из стали 45, при этом имеют высокие перспективы к применению в качестве одной из деталей, составляющих пару трения ответственных узлов, в качестве второй детали возможно использование борированной стали 45.
