Modelling ultrafine particle growth based on flow tube reactor measurements
Authors: Taylor Jr. Michael S. , Higgins Devon N. , Johnston Murray V.
Published: April 2022

Abstract. Flow tube reactors are often used to study the growth of secondary organic aerosol (SOA). Because a significant amount of growth must occur over the short residence time of the flow tube, precursor mixing ratios in a flow tube experiment are generally much higher than ambient values. In this study, a model of SOA growth based on condensation of nonvolatile molecules, partitioning of semivolatile molecules, and reaction of semivolatile molecules in the particle volume to produce nonvolatile dimers, is used to compare particle growth under atmospherically relevant conditions to those under typical flow tube conditions. The focus is on the diameter growth of particles in the 10 to 100 nm diameter range, where growth rates can have a substantial impact on formation of cloud condensation nuclei. In this size range, both particle surface- and volume-limited kinetics may apply. Modelling shows that the higher precursor mixing ratios of a flow tube experiment cause surface-limited kinetics to be more prevalent in the flow tube than under atmospheric conditions. SOA formation is characterized by the growth yield (GY), defined as the yield of oxidation products that are to grow the particles. Defined in this way, GY is the sum of all nonvolatile products that condensationally grow particles plus a portion of semivolatile particles that react in the particle volume to give nonvolatile dimers. Modelling shows that GY actually changes as a function of time within the flow tube. The experimentally determined GY from the measured inlet-outlet diameter change of particles in a flow tube experiment closely tracks the average of the time-dependent GY obtained from modelling specific chemical processes. Modelling is also used to explore the effects of seed particle size (40, 60, 80 nm dia.), phase state (deliquesced vs. effloresced), and surface state (interfacial water), as well as precursor mixing ratio, all of which are shown to substantially influence SOA formation under the conditions studied.

Abstract. Nitrous oxide (N2O) is an important ozone-depleting greenhouse gas produced and consumed by microbially mediated nitrification and denitrification pathways. Estuaries are intensive N2O emission regions in marine ecosystems. However, the potential contributions of nitrifiers and denitrifiers to N2O sources and sinks in China's estuarine and coastal areas are poorly understood. The abundance and transcription of six key microbial functional genes involved in nitrification and denitrification, as well as the clade II-type nosZ gene-bearing community composition of N2O reducers, were investigated in four estuaries spanning the Chinese coastline. The results showed that the ammonia-oxidizing archaeal amoA genes and transcripts were more dominant in the northern Bohai Sea (BS) and Yangtze River estuaries, which had low nitrogen concentrations, while the denitrifier nirS genes and transcripts were more dominant in the southern Jiulong River (JRE) and Pearl River estuaries, which had high levels of terrestrial nitrogen input. Notably, the nosZ clade II gene was more abundant than the clade I-type throughout the estuaries except for in the JRE and a few sites of the BS, while the opposite transcript distribution pattern was observed in these two estuaries. The gene and transcript distributions were significantly constrained by nitrogen and oxygen concentrations, as well as salinity, temperature, and pH. The nosZ clade II gene-bearing community composition along China’s coastline had a high diversity and was distinctly different from that in the soil and marine oxygen-minimum-zone waters. By comparing the gene distribution patterns across the estuaries with the distribution patterns of the N2O concentration and flux, we found that denitrification may principally control the N2O emissions pattern.

Abstract. A mismatch between model- and proxy-based Holocene climate change, known as the Holocene conundrum, may partially originate from the poor spatial coverage of climate reconstructions in, for example, Asia, limiting the number of grid-cells for model-data comparisons. Here we investigate hemispheric, latitudinal, and regional mean time-series as well as anomaly maps of pollen-based reconstructions of mean annual temperature, mean July temperature, and annual precipitation from 1676 records in the Northern Hemisphere extratropics. Temperature trends show strong latitudinal patterns and differ between (sub-)continents. While the circum-Atlantic regions in Europe and eastern North America show a pronounced mid-Holocene temperature maximum, western North America shows only weak changes and Asia mostly a continuous Holocene temperature increase but with strong latitudinal differences. Likewise, precipitation trends show certain regional peculiarities such as the pronounced mid-Holocene optimum between 30 and 40° N in Asia and Holocene increasing trends in Europe and western North America which can all be linked with Holocene changes of the regional circulation pattern linked to temperature change. Given a background of strong regional heterogeneity, we conclude that the calculation of global or hemispheric means which initiated the Holocene conundrum debate should focus more on understanding the spatio-temporal patterns and their regional drivers.
Cryo-seismicity triggered by ice mass discharge through the Antarctic subglacial hydrographic network
Authors: Danesi Stefania , Salimbeni Simone , Borghi Alessandra , Urbini Stefano , Frezzotti Massimo
Published: April 2022

Abstract. We analyze seismic time series collected during experimental campaigns in the area of the David Glacier, South Victoria Land, Antarctica, between 2003 and 2016. We observe hundreds of repeating seismic events, characterized by highly correlated waveforms (cross-correlation > 0.95), which mainly occur in the floating area between the grounding and the floating line of the ice stream. The joint analysis of seismic occurrences and observed local tide measurements seem to show that seismicity is not triggered by a seasonal, regular, periodic forcing such as the ocean tide, but more likely by transient irregular impulses. We consider possible environmental processes and their impact on the coupling between the glacier flow and the bedrock brittle failure. Our results suggest that clustered and repeated seismic events may be correlated with transient episodes of mass ice discharge (observed by satellite GRACE and GRACE-FO experiments) through the subglacial hydrographic system that originates upstream of the glacier and extends to the grounding zone, lubricating the interface with the bedrock.
In situ measurements of meltwater flow through snow and firn in the accumulation zone of the SW Greenland Ice Sheet

Published: April 2022

Abstract. The Greenland Ice Sheet is losing mass, part of which is caused by increasing runoff. The location of the runoff limit, the highest elevation from which meltwater finds its way off the ice sheet, plays an important role in the surface mass balance of the ice sheet. The recently observed rise in runoff area might be related to an increasing amount of refreezing: ice layer development in the firn hinders vertical percolation and promotes lateral runoff. To investigate meltwater flow near the runoff limit in the accumulation zone on the southwest Greenland Ice Sheet, we carried out in situ measurements of hydrological processes and properties of firn and snow. The hydraulic conductivity of icy firn in pre-melt conditions measured using a portable lysimeter ranges from 0.17 to 12.8 m hr-1, with flow predominantly occurring through preferential flow fingers. Lateral flow velocities of meltwater on top of the near-surface ice slab at the peak of the melt season measured by salt dilution- and tracer experiments range from 1.3 to 15.1 m hr-1. With these lateral flow velocities the distance between the slush limit, the highest elevation where liquid water is visible on the ice sheet surface, and the runoff limit could be up to 4 km in regions where near-surface ice slabs are present. These measurements are a first step towards an integrated set of hydrological properties of firn on the SW Greenland Ice Sheet, and show evidence that meltwater runoff might occur from elevations above the visible runoff area.

The role of föhn winds in eastern Antarctic Peninsula rapid ice shelf collapse
Authors: Laffin Matthew K. , Zender Charles S. , van Wessem Melchior , Marinsek Sebastián
Published: April 2022

Abstract. Ice shelf collapse reduces buttressing and enables grounded
glaciers to contribute more rapidly to sea-level rise in a warming climate.
The abrupt collapses of the Larsen A (1995) and B (2002) ice shelves on the
Antarctic Peninsula (AP) occurred, at least for Larsen B, when long-period
ocean swells damaged the calving front and the ice shelf was inundated with
melt lakes that led to large-scale hydrofracture cascades. During collapse,
field and satellite observations indicate föhn winds were present on
both ice shelves. Here we use a regional climate model and machine learning
analyses to evaluate the contributory roles of föhn winds and associated
melt events prior to and during the collapses for ice shelves on the AP.
Föhn winds caused about 25 % ± 3 % of the total annual melt in
just 9 d on Larsen A prior to and during collapse and were present during
the Larsen B collapse, which helped form extensive melt lakes. At the same
time, the off-coast wind direction created by föhn winds helped melt and
physically push sea ice away from the ice shelf calving fronts that allowed
long-period ocean swells to reach and damage the front, which has been
theorized to have ultimately triggered collapse. Collapsed ice shelves
experienced enhanced surface melt driven by föhn winds over a large
spatial extent and near the calving front, whereas SCAR inlet and the Larsen
C ice shelves are affected less by föhn-wind-induced melt and do not
experience large-scale melt ponds. These results suggest SCAR inlet and the
Larsen C ice shelves may be less likely to experience rapid collapse due to
föhn-driven melt so long as surface temperatures and föhn occurrence
remain within historical bounds.

The right to a healthy environment is one of the fundamental rights enshrined in the Constitution of the Republic of Moldova. The institution of public procurement, on the other hand, is one that can make a significant contribution to setting clear guidelines for environmental protection through appropriate regulations and public procurement policies that would give environmental standards a leading place. In the article below we emphasize that the regulation of environmental criteria in public procurement law is only a necessary condition, but by no means sufficient. There is a whole set of prerequisites that should be met for effective regulations in terms of environmental benefits.
Analysis of the experience of state support for the development of the eco-economy market in the countries of the European Union
Authors:   Academy of Economic Studies of Moldova, Chirtoca Alexei
Published: April 2022

The global eco-economy market started to form only in recent decades, it shows high annual growth rates, significantly exceeding the growth of other sectors of the economy, and also opens up new market niches. The rapid development of the world economy actualizes the need to study the patterns of formation and mechanisms of state support for the eco-economy market. The introduction of management focused on greening, in particular, by entering the eco-economy market, has not yet become widespread, including due to the presence of problems with the choice of management tools that consider the specifics of this market. The article examines the experience of state support for the development of the eco-economy market in the countries of the European Union by the method of introducing environmentallyoriented innovations that contributed to solving current economic and environmental problems at the European level.

After the signing of the Association Agreement between the Republic of Moldova and the European Union on June 27, 2014, it was obvious that the European option becomes a priority for the future of the Republic of Moldova. Although the political forces present in the arena of Moldova were divided into two almost equal segments: some opted for European Integration, others opted for the Eurasian Union. In this context, the European aspirations of the Republic of Moldova were clearly outlined and, in the same way, the main impediments to EU integration were formulated. The contradictions between the two options were like litmus paper that marked the differences and possible obstacles to integration. The task of the politicians was to make the road outlined in the Association Agreement as fast as possible, with tangible results and the achievement of the goals outlined in the Agreement. But it was not to be, the road traveled was much more difficult, with multiple errors, hesitations and political failures due to which the Republic of Moldova is still at a crossroads of history
Developing instruments for the recovery of criminal assets
Authors:   Moldova State University, Scorpan Alesea
Published: April 2022

There is a global trend towards the widespread application of confiscation of criminal assets, especially those obtained as a result of corruption offenses. Given that criminals are becoming increasingly intelligent and already know the tools used by law enforcement agencies, it is becoming increasingly difficult to fight crime. Through this article we set out to research new methods used by other states or proposed by some authors in the field of recovery of criminal assets. We all know the tools such as confiscation, requests for international legal assistance, seizure, but these are the tools that float above the water, long visible and known not only by law enforcement agencies but also by criminals. What is of real interest are the instruments that are at the ,,bottom of the sea” where not every state had the courage to sink, but they found a real treasure, materialized in recovered criminal property. Some tools are taken from the practice of British law, others are just ideas from practitioners who have worked in the field of criminal property recovery. Confiscation of property is an important tool in the fight against crime, we do not deny the importance of official instruments, but we consider it appropriate to widen the limits imposed by national legislation in this field.

Öğrencilerin ders sunumlarında tercih ettikleri yazı tipleri
Authors: YÜCEL Kaan
Published: April 2022

Akademik hayatın vaz geçilmez unsurlarından biri öğrencilerimiz için ders sunumları hazırlamaktır ve bu konuda akademisyenlerin sağ kolu PowerPoint® Microsoft Office programıdır. PowerPoint® sunumları eğitimde kullanımı ile ilgili çalışmalar 1990’ların ortalarında literatürdeki yerlerini almaya başlamıştır. Ders slaytlarının en önemli yapı taşının yazı tipi olduğu belirtilmiştir. Slaytların hızlı okunmasında yazı tipi seçiminin önemli olduğu bildirilmiştir. Bununla birlikte öğrencilerin sunumlarda tercih ettiği yazı tipleri ile ilgili çalışmalar kısıtlı sayıdadır. Yazı tipleri harflerin uçlarındaki dekoratif eklerin olup olmamasına göre ikiye ayrılırlar. “Serif” yazı tipinde harfin uçlarına dekorasyon amaçlı bir çıkıntı eklenmektedir (Times New Roman gibi). Daha sade görünümlü ve bu çıkıntının olmadığı yazı tipleri de “sans serif” yazı tipleridir (Arial gibi). Çalışmamızda sağlıkla ilgili bölümlerde okuyan öğrencilerin derslerdeki PowerPoint® sunumlarında başlık ve metin için tercih ettikleri yazı tipini ve nedenlerini araştırdık. İzmir Demokrasi Üniversitesi Tıp Fakültesi, Diş Hekimliği Fakültesi, Sağlık Bilimleri Fakültesi ve Sağlık Hizmetleri Meslek Yüksekokulu’nda eğitim gören, 16 sınıfta eğitim gören öğrencilere PowerPoint® sunumlarında başlıklarda ve metinlerde 26 farklı yazı tipi arasından tercihlerini öğrenmek amacıyla Microsoft Office Forms®’da (http://forms.office.com) sekiz soruluk bir anket uyguladık. Öğrenciler tercih nedenlerinden kolay ve açıkça okunabilmesi, estetik olması, aşina gelmesi/popüler olması, daha profesyonel ve ilgi çekici görülmesi yanıtlarından bir veya birden fazla seçebilmekteydi. Anketin ulaştığı 1324 öğrenciden 804’ü anketi yanıtladı. Toplamda anketin yanıtlanma oranı %60.7 idi. Başlıklar ve metin için Arial, Times New Roman ve Calibri olmak üzere ilk üç sıralama aynı olmuştur. Verdana da ilk beşte yer almıştır. Bahnschrift başlıklar, Candara da metin için öğrencilerin ilk beşteki diğer yazı tipleriydi. İlk beş tercihi erkek ve kız öğrencilerde farklılık göstermiştir. Ders sunumlarında öğrencilerin hem başlık hem de metin için sans serif grubundaki yazı tiplerini tercih ettiği görülmüştür. Sans serif yazı tipleri özellikle kolay ve açıkça okundukları için seçilmişlerdi. İlgi çekici görünme kriteri hem sans serif hem de serif yazı tipleri için genel görünümle uyumlu bir şekilde en az öneme sahip kriterdi. Öğrencilere geniş bir spektrumda yazı tipi alternatifi sunulan, cinsiyet ve okula göre sans serif ve serif yazı tiplerinin karşılaştırıldığı öğrencilerin yazı tipi tercihlerinin incelendiği bu çalışma bu sunumları hazırlayan öğretim üyeleri/görevlilerin yazı tipi tercihleri ve nedenleri sorularak tamamlanabilir. Hem bilgisayar ekranında hem de basılı şekilde ders notu olarak çıkartıldığında net olarak okunabilecek Verdana, Arial gibi yazı tiplerinin sunumlarda seçilmesi daha makul gözükmektedir. Times New Roman yazı tipi de serif grubunda olmasına rağmen günümüz teknolojisi ile açık bir şekilde okunması ile tercih edilebilir.
Программный комплекс построения квазилинейных регрессий по критериям точности и нелинейности
Authors: Караулова Анна Витальевна , Базилевский Михаил Павлович
Published: April 2022

Работа посвящена проблеме выбора структурных спецификаций квазилинейных регрессионных моделей. Такие регрессии довольно просто оцениваются, но наличие в них нелинейных преобразований переменных затрудняет интерпретацию их оценок. Ранее авторами была сформулирована двухкритериальная задача выбора спецификации квазилинейной регрессии, состоящая в максимизации коэффициента детерминации и одновременной минимизации общего критерия нелинейности. Для большого числа переменных такая формулировка превращается в сложную вычислительную задачу. В настоящей работе впервые описан разработанный нами программный комплекс КВАРТОН-1, полностью автоматизирующий решение двухкритериальной задачи. В нем предусмотрена работа в двух режимах. В первом из них формируется множество Парето, с помощью которого пользователь может визуально прослеживать последовательную трансформацию линейной регрессии в нелинейную модель и выбирать наиболее приемлемую альтернативу. Во втором режиме сначала автоматически исключаются все значительно нелинейные регрессии, а из оставшихся выбирается лучшая по критерию детерминации. В обоих режимах предусмотрена возможность исключения моделей с незначимыми по t-критерию Стьюдента коэффициентами. С помощью КВАРТОН-1 была успешно решена задача моделирования грузовых железнодорожных перевозок в Иркутской области.

Authors: Асадуллаев Рустам Геннадьевич , Кузьменко Николай Иванович
Published: April 2022

В данной работе представлена технология распознавания сельскохозяйственных культур по данным дистанционного зондирования Земли. Апробация технологии была проведена на сельскохозяйственных землях Белгородской области Российской Федерации. В соответствии со статистикой севооборота были выбраны следующие сельскохозяйственные культуры: пшеница, ячмень, кукуруза, подсолнечник, соя, сахарная свекла, многолетние травы и пары. В качестве входных данных были использованы мультиспектральные снимки со спутника Sentinel-2 уровня обработки MSI L2A, а именно каналы RGB-спектра, SWIR и NIR. Из полученных данных были составлены временные ряды в вегетационные периоды за 2018–2020 годы. Разработан алгоритм устранения пропусков данных в дни высокой облачности для повышения качества распознавания. В качестве модели классификатора была использована сверточно-рекуррентная нейронная сеть. Разработанная модель на тестовых данных показала общую меру точности f-мера 88,7 %. Предложенная архитектура нейронной сети также применима в других регионах со схожей посевной структурой, фенологическими показателями культур и схожими климатическими условиями.

Published: April 2022

В статье рассматривается реализация алгоритма стабилизации изображения на основе суммы абсолютных разностей между областями соседних кадров. Находится относительное и абсолютное смещение между кадрами за минимальный интервал времени между зонами интереса. Обработка информации осуществляется параллельно в 16 потоков для минимизации времени задержки, а также предложена альтернативная версия алгоритма с использованием вейвлет Хаара и оператора Собеля, что позволяет повысить основные характеристики алгоритма и уменьшить влияние шумов на изображении и оптических искажений. Проведена оценка требуемых ресурсов для возможности запуска разработанного алгоритма на программируемой логической интегральной схеме.
Экономические аспекты новой Стратегии национальной безопасности Российской Федерации
Authors: Бухвальд Евгений Моисеевич
Published: April 2022

До настоящего времени не удалось добиться органичной интеграции стратегических документов по национальной безопасности в единую практику стратегического планирования на всех уровнях управления. Содержащееся в действующем законодательстве указание на стратегию безопасности как один из ключевых документов стратегического планирования, по сути, не реализуется. Стратегированию национальной безопасности посвящено значительное число научных работ, однако пути согласования документов национальной безопасности и по социально-экономическому развитию в целом все еще остаются недостаточно исследованными. Целью работы выступает анализ возможностей проекции экономических параметров безопасности на иные документы стратегического планирования. В методологическом аспекте основой работы являются исследования по экономико-правовым проблемам национальной, в т. ч. экономической безопасности, сформулированные в работах Л.И. Абалкина, В.К. Сенчагова, С.Ю. Глазьева и других авторов.
