Aerosol characteristics and polarimetric signatures for a deep convective storm over north-western part of Europe – modeling and observations
Authors: Shrestha Prabhakar , Mendrok Jana , Brunner Dominik
Published: April 2022

Abstract. The Terrestrial Systems Modeling Platform (TSMP) was extended with a chemical transport model and polarimetric radar forward operator to enable detailed studies of aerosol-cloud-precipitation interactions. The model was used at km scale (convection permitting) resolution to simulate a deep convective storm event over Germany, which produced large hail, high precipitation and severe damaging winds. The ensemble model simulation was in general able to capture the storm structure, its evolution and spatial pattern of accumulated precipitation - however, the model was found to underestimate regions of high accumulated precipitation (> 35 mm) and convective area fraction in the early period of the storm. While the model tends to simulate too high reflectivity in the downdraft region of the storm above the melting layer (mostly contributed by graupel), the model also simulates very weak polarimetric signatures in this region, compared to the radar observations. The findings of the study remained almost unchanged when using much narrow cloud drop size distribution (CDSD), acknowledging the missing feedback between aerosol physical and chemical properties and CDSD shape parameters. The km scale simulation showed that the strong updraft in the convective core produces "aerosol tower" like features, increasing the aerosol number concentrations and hence increasing the cloud droplet number concentration and reducing the mean cloud drop size. This could be also a source of discrepancy between the simulated polarimetric features like differential reflectivity (ZDR) and specific differential phase (KDP) columns along the vicinity of the convective core compared to the X-band radar observations. Besides, the evaluation of simulated trace gases and aerosols were encouraging, however a low bias was observed for aerosol optical depth (AOD), which could be partly linked to an underestimation of dust mass in the forcing data associated with a Saharan dust event. This study illustrates the importance and the additional complexity associated with the inclusion of chemistry transport model when studying aerosol-cloud-precipitation interactions. But, along with polarimetric radar data for model evaluation, it allows to identify and better constrain the traditional 2-moment bulk cloud microphysical schemes used in the numerical weather prediction models for weather and climate.
Aqueous chemical bleaching of 4-nitrophenol brown carbon by hydroxyl radicals; products, mechanism, and light absorption
Authors: Witkowski Bartłomiej , Jain Priyanka , Gierczak Tomasz
Published: April 2022

Abstract. The reaction of hydroxyl radicals (OH) with 4-nitrophenol
(4NP) in an aqueous solution was investigated at pH = 2 and 9. The molar
yield of the phenolic products quantified was ca. 0.2 at pH = 2 and 0.4 at
pH = 9. The yield of 4-nitrocatechol (4NC) was higher at pH = 9. At the same time, a lower number of phenolic products was observed at pH = 9 due to
irreversible reactions of some phenols formed at pH > 7. Mineralization investigated with a total organic carbon (TOC) analyzer
showed that after 4NP was completely consumed, approximately 85 % of the
organic carbon remained in the aqueous solution. Moreover, as inferred from
the TOC measurements and the molar yields of the phenols formed, 65 % of
the organic carbon that remained in the aqueous solution was attributed to
the non-aromatic products. The light absorption of the reaction solution
between 250 and 600 nm decreased as a result of the OH reaction with 4NP.
However, the 4NP solution showed a noticeable resistance to the chemical
bleaching reaction investigated due to the formation of light-absorbing
by-products. This phenomenon effectively prolongs the timescales of the chemical bleaching of 4NP by OH by a factor of 3–1.5 at pH 2 and 9,
respectively. The experimental data acquired indicated that both photolysis
and the reaction with OH can be important processes for the removal of
light-absorbing organic compounds from cloud water particles containing 4NP.

Abstract. Volcanic eruptions eject large amounts of ash and trace gases such
as sulfur dioxide (SO2) into the atmosphere. A significant difficulty
in mitigating the impact of volcanic SO2 clouds on air traffic safety
is that these gas emissions can be rapidly transported over long distances.
The use of space-borne instruments enables the global monitoring of volcanic
SO2 emissions in an economical and risk-free manner. Within the
European Space Agency (ESA) Sentinel-5p+ Innovation project, the S5P
SO2 layer height (S5P+I: SO2LH) activities led to the improvements of
the retrieval algorithm and generation of the corresponding near real-time
S5P SO2 LH products. These are currently operationally provided, in
near real-time, by the German Aerospace Center (DLR) within the framework of the
Innovative Products for Analyses of Atmospheric Composition (INPULS)
project. The main aim of this paper is to present its extensive
verification, accomplished within the S5P+I: SO2LH project, over major
recent volcanic eruptions, against collocated space-borne measurements from
the IASI/Metop and CALIOP/CALIPSO instruments as well as assess its impact
on the forecasts provided by the Copernicus Atmospheric Monitoring Service (CAMS). The mean difference between S5P and IASI observations for the Raikoke
2019, the Nishinoshima 2020 and the La Soufrière-St Vincent 2021
eruptive periods is ∼ 0.5 ± 3 km, while for the Taal 2020
eruption, a larger difference was found, between 3 ± 3 km and 4 ± 3 km. The comparison of the daily mean SO2 LH further
demonstrates the capabilities of this near real-time product, with slopes
between 0.8 and 1 and correlation coefficients ranging between 0.6 and 0.8.
Comparisons between the S5P SO2 LH and the CALIOP/CALIPSO ash plumes
revealed an expected bias at −2.5 ± 2 km, considering that the injected
SO2 and ash plume locations do not always coincide over an eruption.
Furthermore, the CAMS assimilation of the S5P SO2 LH product led to much
improved model output against the non-assimilated IASI LH, with a
mean difference of 1.5 ± 2 km, compared to the original CAMS analysis,
and improved the geographical spread of the Raikoke volcanic plume following
the eruptive days.

Abstract. The new single pixel TROPESS (TRopospheric Ozone and its Precursors from Earth System Sounding) profile retrievals of carbon monoxide (CO) from the Cross-track Infrared Sounder (CrIS) are evaluated using vertical profiles of in situ observations from the National Oceanic and Atmospheric Administration (NOAA) Global Monitoring Laboratory (GML) aircraft program and from the Atmospheric Tomography Mission (ATom) campaigns. The TROPESS optimal estimation retrievals are produced using the MUSES (MUlti-SpEctra, MUlti-SpEcies, MUlti-Sensors) algorithm which has heritage from retrieval algorithms developed for the EOS/Aura Tropospheric Emission Spectrometer (TES). TROPESS products provide retrieval diagnostics and error covariance matrices that propagate instrument noise as well as the uncertainties from sequential retrievals of parameters such as temperature and water vapor that are required to estimate the carbon monoxide profiles. The validation approach used here evaluates biases in column and profile values and the validity of the retrieval error estimates using the mean and variance of the compared satellite and aircraft observations. CrIS-NOAA GML comparisons had biases of 0.6 % for partial column average volume mixing ratios (VMR) and (2.3, 0.9, -4.5) % for VMR at (750, 511, 287) hPa vertical levels, respectively, with standard deviations from 9 % to 14 %. CrIS-ATom comparisons had biases of -0.04 % for partial column and (2.2, 0.5, -3.0) % for (750, 511, 287) hPa vertical levels, respectively, with standard deviations from 6 % to 10 %. The reported observational errors for TROPESS CrIS CO profiles have the expected behavior with respect to the vertical pattern in standard deviation of the comparisons. These comparison results give us confidence in the use of TROPESS CrIS CO profiles and error characterization for continuing the multi decadal record of satellite CO observations.

Abstract. European flood frequency and intensity change on a multidecadal scale. Floods were more frequent in the 19th (central Europe) and early
20th century (western Europe) than during the mid-20th century and
again more frequent since the 1970s. The causes of this variability are not
well understood and the relation to climate change is unclear. Palaeoclimate
studies from the northern Alps suggest that past flood-rich periods
coincided with cold periods. In contrast, some studies suggest that more
floods might occur in a future, warming world. Here we address the
contribution of atmospheric circulation and of warming to multidecadal flood
variability. For this, we use long series of annual peak streamflow, daily
weather data, reanalyses, and reconstructions. We show that both changes in
atmospheric circulation and moisture content affected multidecadal changes
of annual peak streamflow in central and western Europe over the past two
centuries. We find that during the 19th and early 20th century,
atmospheric circulation changes led to high peak values of moisture flux
convergence. The circulation was more conducive to strong and long-lasting
precipitation events than in the mid-20th century. These changes are
also partly reflected in the seasonal mean circulation and reproduced in
atmospheric model simulations, pointing to a possible role of oceanic
variability. For the period after 1980, increasing moisture content in a
warming atmosphere led to extremely high moisture flux convergence. Thus,
the main atmospheric driver of flood variability changed from atmospheric
circulation variability to water vapour increase.

Abstract. The availability of large amounts of data is starting to impact how the wind energy community works. From turbine design to plant layout, construction, commissioning, and maintenance and operations, new processes and business models are springing up. This is the process of digitalisation, and it promises improved efficiency and greater insight, ultimately leading to increased energy capture and significant savings for wind plant operators, thus reducing the levelized cost of energy. Digitalisation is also impacting research, where it is both easing and speeding up collaboration, as well as making research results more accessible. This is the basis for innovations that can be taken up by end users. But digitalisation faces barriers. This paper uses a literature survey and the results from an expert elicitation to identify three common industry-wide barriers to the digitalisation of wind energy. Comparison with other networked industries and past and ongoing initiatives to foster digitalisation show that these barriers can only be overcome by wide-reaching strategic efforts, and so we see these as "Grand Challenges" in the digitalisation of wind energy. They are, first, the need to create reusable data frameworks; secondly, the need to connect people to data to foster innovation; and finally, the need to enable collaboration and competition between organisations. The Grand Challenges thus include a mix of technical and cultural aspects that will need collaboration between businesses, academia, and government to solve. Working to mitigate them is the beginning of a dynamic process that will position wind energy as an essential part of a global clean energy future.
Digital together: Creative writing, collaborative residencies and cultural exchange in a COVID-constrained world
Authors: Iyer Sreedhevi , Pang Alvin , Carlin David
Published: April 2022

Since 2014, the Writers Immersion and Cultural Exchange (WrICE) program has sought to invite genuine trans-cultural encounters and dialogue among peer creative writers from different nations, cultural backgrounds, interests and life experiences across Asia and Australia. These have been enacted through in-person collaborative residencies, designed and staged based on a set of five compositional principles. In 2020, these principles were challenged, tested and elaborated in new ways through a new WrICE residency conducted entirely online: a move made necessary by the COVID-19 pandemic and its conditions of physical separation. Our findings from this digital residency experience offer insights into future directions for approaching transnational collaboration and dialogue among writers, artists, scholars, activists and others in a more constrained world, during and after the pandemic.
“O brilhar da natureza é uma parusia superior”:
Authors: Rodrigues Ramos Daniel
Published: April 2022

O artigo é uma discussão fenomenológica acerca da natureza. Fundamentada no pensamento tardio de Heidegger, ela se desenvolve em torno da superação da determinação metafísica da realidade natural enquanto presença constante. Para tanto, toma-se como guia da reflexão um verso das poesias tardias de Hölderlin, cujo aclaramento conduz ao questionamento do sentido da noção de presença (ousia) e da sua referência com a ausência (apousia) e, em seguida, da relação essencial entre ser e aparência. Nesta direção, mostra-se que a sublime aparição da natureza é a luta e unidade entre parusia e apousia.
natureza como "espírito nascente":
Authors: Silva Claudinei Aparecido de Freitas da
Published: April 2022

Tendo, pois, como pano de fundo o horizonte de uma fenomenologia da natureza, o texto, a seguir, explora uma proposição emblemática enunciada por Gabriel Marcel: a ideia da “natureza como espírito nascente”. Para tanto, a fim de melhor compreender o sentido e alcance dessa tese, a exposição se divide em duas partes correlatas: a primeira, retrospectivamente negativa, reconstitui a crítica marceliana ao naturalismo e ao idealismo vistos como dois gestos concêntricos à medida que não atribuem qualquer estatuto ou significação à natureza. A segunda, mais positiva ou propositiva, restitui, numa direção heurística, a experiência matricial da natureza como espírito nascente, ou seja, confere pleno reconhecimento a uma acepção originariamente espiritual da natureza como fenômeno co-nascente.

Object: It has been well-established that obesity, or the fat content of the belly, is associated with diabetes, heart conditions, metabolic syndrome and back pain. With regard to back pain, this study aimed to assess the forces that incremental amounts of belly fat exert on the spine. Methods: A finite element analysis (FEA) was performed with a 3D CAD model of the spine using data for various populations from the Dallas Heart Study. Results: There were significant differences in the forces exerted on the spine by belly fat among ethnic groups. Conclusions: These findings should help clarify the stress forces experienced by the spine in relation to waist circumference and could help to explain the association between obesity and back pain.

Authors: Krasovskyi Serhii , Kovrov Oleksandr , Klimkina Iryna
Published: April 2022

Development of alternative energy sources are increasing now, but the use of minerals still plays an important role in the industrial sector, and Ukraine is no exception. DTEK Energo is a key player in Ukraine's coal industry. 13 mines and 4 coal concentrators represent production capacities of this segment. Dumps and sludge storages contain about 1.3 billion tons of rocks with an annual replenishment of about 60 million tons. These areas occupy large areas and require reclamation in the future. This paper presents the results of physico-chemical analysis of DTEK SU "Heroiv Kosmosu" coal mining dump, namely such indicators as: pH and electrical conductivity of the substrate (EC), nutrient content, concentration of rare earth elements. The results of the obtained data in the future allow to choose the best method of reclamation, involving plants, with subsequent bioleaching of rare earth metals.

Published: April 2022

In the article with the aim of the functioning efficiency of the unified state system of civil protection to minimize the consequences and prevent the depletion or destruction of individual natural complexes and resources (i.e., excessive pollution of the environment and the destructive effects of natural forces and other factors that limit or exclude the possibility of life of a person and the implementation of economic activity under these conditions) the results of further development of the scientific and technical foundations for the implementation of a system for operational monitoring of a certain area have been presented. These results were based on the example of the issues of reconnaissance and clarification of the area parameters contaminated by hazardous chemicals using unmanned aerial vehicles (UAVs) where an environmental emergency has been occurred. It has been established that the main criterion for the effectiveness of the use of UAVs is the time of monitoring the area of an environmental emergency. That time is associated with both the characteristics and the formation of the UAV flight path.

In the article the method of forming a flight path for reconnaissance and clarifying the parameters of the contamination zone of the area with hazardous chemicals by one UAV was presented. Also, the formation of the flight path when using the group flight of the UAV was presented. As a result of the research, it was found that with the group version of monitoring the UAV terrain, the flight time is significantly reduced. This proves the effectiveness of organizing such an option for monitoring a certain area of an emergency environmental situation.
MODIFICATION OF THE QUARTZ LOADING CONTACT CLARIFIERS IN WATER TREATMENT PROCESSES
Authors: Dushkin Stanislav
Published: April 2022

In the article are considered the influence of modification of the quartz loading contact clarifiers on the degree of structural and mechanical hydration of aluminum hydroxide in water treatment processes.

Modification of the molecular structure of the surface of quartz grains of the filter charge increases the dirt capacity and increases the performance of structures. For the modification of filter materials can be used coagulants. Modification of filter materials allows with minimal cost to increase the performance of station of water treatment plants, to improve the quality of filtrate and reduce the cost of water treatment by reducing the consumption of reagents and increase the speed of filtration. The essence of the method is to increase the adhesion of the filter materials by the method of processing it with a solution of the reagent. The process of adhesion of suspended particles usually with a negative charge is more intense relative to the modified loading than the unmodified.

It is established that the use of modified quartz loading allows to reduce the degree of structural and mechanical hydration of aluminum hydroxide, increase the proportion of coagulated impurities, which ultimately allows to intensify water purification processes, namely to reduce reagent costs by an average of 40…50 % with water required quality, while the cost of clarified water is reduced by 25…30 %.
The Takeover Premium: Wealth Creation and Distribution
Authors: Blackshields Adrian , Donnelly Ray
Published: April 2022

We posit that the premium paid on acquisition has two elements: the gain created by the acquisition and the portion of this gain that is captured by the target shareholders. The former derives from synergies and the replacement of inefficient incumbent management in the target. The latter is a function of agency considerations and aspects of the takeover deal. Our empirical results provide evidence that the market for corporate control is a primary determinant of value creation. We also provide evidence that the bargaining strength of the target shareholders impacts on the portion of the gains they procure for themselves.
Financing Irish Firms: A Comparative Study of Irish and Matching US Firms
Authors: Stohs Mark Hoven
Published: April 2022

This paper analyses the interplay of dividends and seasoned equity issuances by Irish firms in a comparative framework with matched US firms. Irish firms have high dividend payout ratios. However, some Irish firms and not others issue equity frequently. The agency theory, that high dividends and issuing equity are connected, is not supported by the evidence. Instead, the frequent Irish issuers use more debt, have less institutional ownership and grow faster, in comparison both to the Irish non-issuers and to their US counterparts. A non-negative market response to equity issuances for growing Irish firms may explain why such firms use new equity to finance their growth.
The Impact of Free Cash Flow on Target and Bidder Probability: A Study of UK Firms 1989-95
Authors: Barnes Edel , Barrett Kevin
Published: April 2022

This study examines the influences on target and bidder probability for UK firms over the period 1989-95. Managerial theory suggests that managers may sub-optimally exercise discretion over free cash flow (FCF). Following Jensen (1986), it is suggested that the take-over market call potentially resolve this FCF problem - firms with high FCF may become bidders or attractive targets to value-optimising predators. The contribution of the study is twofold. A sample of UK firms is examined over a relatively recent time period, where most of the extant literature is more dated and is based on US companies. Importantly, a FCF metric is devised to explore the issue of identification of bidding and target firms, which, it is posited, captures the essence of Jensen’s agency cost model more coherently than metrics currently utilised in related studies. Empirical support for this theory of take-over activity controlling for alternative influences on target/bidder likelihood is documented. Of the drivers of target and bidder probability analysed here, FCF performs strongly and examination of marginal effects suggests that FCF has substantial economic consequences for take-over activity. Application of the proposed Logit model to an out-of-sample group of firms resulted in accurate prediction of targets (bidders) in 73 per cent (7J per cent) of cases respectively. Weaker evidence of a positive role for gearing (prior performance} in the identification of target (bidder) firms is also documented. The precise impact of FCF on acquisition returns is suggested as an important area for future research.
Approaches to Learning: Irish Students of Accounting
Authors: Byrne Marann , Flood Barbara , Willis Pauline
Published: April 2022

Several reports on accounting education have identified the need to improve the quality of student learning. Higher education research identifies the approach to learning as a significant factor affecting the quality of learning. If accounting educators are to find ways of improving the educational experience of their students, they must understand how students learn and the effects of the learning environment on their learning approaches. This study examines the approaches to learning adopted by first year students enrolled on the BA in Accounting and Finance and the Bachelor of Business Studies (BBS) at Dublin City University and assesses the impact of a number of variables in the learning environment on these learning approaches.
An Assessment of the Market Reaction of UK Firms to a Private Placement Announcement
Authors: Cotter John
Published: April 2022

While considerable attention has been paid to market reaction announcements of public equity issues, only a small amount of research has been devoted to their private placement counterparts. This is surprising given that proceeds from the latter are typically used to finance firms’ new investment projects. This paper helps to redress the balance, by applying market model methodology to 78 private equity issue announcements in the UK over the period 1990-1995. Private placement announcements appear to be associated with positive abnormal returns. It is hypothesised that these arise from the unique negotiating structure between management and private clients.
The Timing and Selection Ability of Irish Fund Managers: Parametric and Non-Parametric Tests
Authors: Stevenson Simon
Published: April 2022

This study examines the market timing and selection ability of portfolio managers. It uses both the parametric and non-parametric models proposed by Henriksson and Merton (1981) to analyse Irish funds over the period 1992 to 1997. The results show that Irish fund managers exhibit positive selection ability, however, as with most of the existing empirical evidence, the results for timing ability are less conclusive. The parametric model provides inconclusive evidence, however the non-parametric model does provide some evidence to the contrary. Generally the results are in line with findings in other markets.

The electrical conductivity, thermochemical and electrochemical properties of a system consisting of melts of aluminium trichloride and sodium-lithium chlorides taken in different ratios have been studied. In this system, the electrochemical behaviour of Ni2+ ions via cyclic voltammetry and the electromotive force in the modes of heating and cooling of the system were studied. It was found that the melting temperature of the melts passes through a minimum at a lithium chloride (хLiCl) content from 0.23 to 0.35. A possibility of reducing the starting temperature of a nickel-chloride battery with a partial replacement of sodium chloride with lithium chloride is shown, as well as stabilization of its operation at a minimum temperature of 240 °C. An admissibility of using the optimal compositions of the system as an electrolyte in sodium nickel-chloride batteries has been established. It was found that the composition 0.5AlCl3-0.23LiCl-0.27NaCl has a minimum melting point (111 °C), a minimum activation energy for conductivity (8.9 kJ∙mol-1), and a sufficiently high electrical conductivity (0.53 S∙cm-1 at 250 °C).

This article discusses character-based Christian education and its relevance for the Armajaya Sindagamanik Private Vocational High School (SMKS). This article uses a qualitative approach with a descriptive method. The Christian students of SMKS Armajaya who are considered as the next generation of the nation as well as the church, are currently trapped in a life that is not pleasing to God, such as smoking, misusing technology during learning, lacking respect for teachers, saying dirty words, and not coming on time. to school and so on. Actually, Christian character should be included in the teachings of God's word, but over time, the character of SMKS Armajaya students is decreasing and not leading to the teachings of God's word anymore, so they don't realize that their character is not good. Thus, character education plays an important role in the personal development of students at SMKS Armajaya. Therefore, in this study, various noble values will be discussed, namely: honesty, virtue, courage, discipline, generosity, tolerance, and responsibility as well as character education which begins with a personal encounter with Jesus Christ.Keywords: character; Christian education; students; SKMS Armajaya Sindagamanik AbstrakArtikel ini membahas tentang pendidikan Kristen berbasis karakter dan relevansinya bagi Sekolah Menengah Kejuruan Swasta (SMKS) Armajaya Sindagamanik. Artikel ini menggunakan pendekatan kualitatif dengan metode deskriptif. Siswa-Siswi Kristen SMKS Armajaya yang dianggap sebagai generasi penerus bangsa sekaligus gereja, saat ini terjebak dalam kehidupan yang tidak berkenan di hadapan Allah, seperti merokok, salah menyalahgunakan teknologi pada saat pembelajaran, kurang rasa menghormati guru, berkata kotor, dan tidak datang tepat waktu ke sekolah, dan lainnya. Karakter Kristen seharusnya diikut sertakan pada ajaran firman Allah, namun seiring perkembangan zaman, karakter siswa-siswi SMKS Armajaya semakin menurun dan bukan mengarah pada ajaran firman Allah lagi, sehingga tidak menyadari bahwa karakter mereka sudah kurang baik. Dengan demikian, pendidikan karakter memegang peranan penting dalam pengembangan pribadi siswa-siswi di SMKS Armajaya. Oleh sebab itu, dalam penelitian ini akan dibahas berbagai nilai-nilai luhur, yakni: kejujuran, kebajikan, keberanian, disiplin, kedermawanan, toleransi, dan tanggung jawab serta pendidikan karakter yang dimulai dengan perjumpaan pribadi dengan Yesus Kristus.Kata kunci: karakter; pendidikan kristiani; siswa-siswi; SKMS Armajaya Sindagamanik

Recent studies show the consumption of carbonated milk beverages are becoming popular due to their nutritional and therapeutic effects. Products like kefir, koumiss, carbonated probiotic drinks and sparkling milk. According to research kefir has different health benefits like gastrointestinal proliferation, anti-bacterial spectrum, an anti-carcinogenic effect due to the presence of lactic acid formed during fermentation. It is also good for those who are lactose intolerant because of the high B – galactosidase activity enzyme which helps break down lactose sugar. Koumiss is first used by Mongolian people to treat tuberculosis, ulcers and hepatitis. It is rich in vitamin C, A, E, D and antibiotics. Carbonated probiotic drinks help in maintaining cholesterol level because lactic acid hinders the growth of bacteria in the small intestine by attaching the hexagen. Carbonated blueberry flavoured milk helps to reduce the risk of cardiovascular diseases, anti-inflammatory effects and some forms of cancer because blueberry is a source of vitamins, flavonoids and other phenolic compounds (anthocyanins).
