Published: April 2024

Reversed-phase (RP) liquid chromatography is an important tool for the characterization of materials and products in the pharmaceutical industry. Method development is still challenging in this application space, particularly when dealing with closely-related compounds. Models of chromatographic selectivity are useful for predicting which columns out of the hundreds that are available are likely to have very similar, or different, selectivity for the application at hand. The hydrophobic subtraction model (HSM1) has been widely employed for this purpose; the column database for this model currently stands at 750 columns. In previous work we explored a refinement of the original HSM1 (HSM2) and found that increasing the size of the dataset used to train the model dramatically reduced the number of gross errors in predictions of selectivity made using the model. In this paper we describe further work in this direction (HSM3), this time based on a much larger dataset (43,329 total measurements) containing selectivities for compounds covering a broader range of physicochemical properties compared to HSM1. This includes multiple compounds that are actual active pharmaceutical ingredients and related synthetic intermediates and impurities, as well as multiple pairs of closely related structures (e.g., geometric and cis-/trans- isomers). The HSM3 model is based on retention measurements for 75 compounds using 13 RP stationary phases and a mobile phase of 40/60 acetonitrile/25 mM ammonium formate buffer at pH 3.2. This data-driven model produced predictions of ln(alpha) (chromatographic selectivity using ethylbenzene as the reference compound) with average absolute errors of approximately 0.033, which corresponds to errors in alpha of about 3 %. In some cases, the prediction of the trans-/cis- selectivities for positional and geometric isomers was relatively accurate, and the driving forces for the observed selectivity could be inferred by examination of the relative magnitudes of the terms in the HSM3 model. For some geometric isomer pairs the interactions mainly responsible for the observed selectivities could not be rationalized due to large uncertainties for particular terms in the model. This suggests that more work is needed in the future to explore other HSM-type models and continue expanding the training dataset in order to continue improving the predictive accuracy of these models.

Published: April 2024

Poly(3,4-ethylenedioxythiophene)-functionalized (PEDOT) MIL-101(Cr) nanoparticles were deposited via drop-casting onto interdigitated electrodes (IDEs). The application of an alternating potential during drop-casting allowed precise spatioselective deposition of the nanoparticles in the interelectrode gaps, generating percolating nanoparticle chains aligned between the finger electrodes. The resulting conductivities of the aligned and chained samples were up to 4 orders of magnitude higher than that of unaligned samples prepared via regular drop-casting. The performance of the unaligned and aligned samples for resistive humidity sensing was investigated, whereby the aligned samples showed a conductivity gain of 230 times at a relative humidity of 90% versus 10%, whereas the unaligned samples showed a lower gain of 40 times at relative humidity 90% versus 10%. Further, the aligned samples could also be utilized as capacitive humidity sensors, showing a change of sensitivity at different frequencies for the aligned sample, whereas unaligned samples show a resistive behavior unsuitable for capacitive sensing. This work demonstrates that simple drop-casting when carried out in conjunction with an applied alternating potential exerts dielectrophoretic control allowing for precise spatioselective deposition, thus leading to higher sample conductivity and enhanced performances for humidity sensing.

Authors: Jannard Louis-Philippe
Published: April 2024

Basé sur une étude empirique des pratiques de l’Agence des services frontaliers du Canada (ASFC) relatives à la détention des personnes non citoyennes, cet article explore deux dimensions interreliées du fonctionnement des frontières, soit la discrétion, qui imprègne l’architecture du droit de l’immigration, de même que les réseaux d’acteurs qui participent, de façon croissante, à leur mise en œuvre. L’intersection de ces dimensions révèle un aspect central du travail qu’implique l’exercice du pouvoir discrétionnaire de détention par les membres du personnel de l’ASFC, c’est-à-dire la recherche et le partage d’informations. En effet, la mise en détention des personnes non citoyennes donne lieu à la collecte de nombreux renseignements auprès de différents acteurs et selon diverses modalités de collaboration. À partir d’entretiens réalisés avec des agentes et agents de l’ASFC, cet article documente les multiples personnes et organisations partenaires qui sont mobilisées dans cette recherche d’informations, illustrant la complexité de l’exercice de ce pouvoir discrétionnaire ainsi que les éléments du contexte organisationnel et social qui l’orientent et le contraignent.
DESAFIOS AMBIENTAIS NA BACIA DO RIO PASSA-TRÊS: Impactos das mudanças no uso da terra nos recursos hídricos
Authors: Martins Wellington Ribeiro , Silva Adriana Aparecida , Castro Joana D'arc Bardella
Published: April 2024

O trabalho teve como objetivo analisar os impactos das mudanças no uso da terra na área da bacia hidrográfica do rio Passa-Três, em Uruaçu, Goiás, sobre os recursos hídricos, mediante a avaliação da ocupação e uso da terra entre os anos de 1985 a 2021. Para isso, utilizou-se o mapeamento desenvolvido pelo Projeto MapBiomas para a geração dos mapas de uso e cobertura da terra nos anos 1985, 2003 e 2021, assim como os mapas de declividade e tipos de solo, a fim de estabelecer relações entre o uso da terra e as características físicas do terreno. Todos os mapas foram gerados por meio do software livre QGIS 3.22. A dinâmica do uso e cobertura da terra apresentou uma tendência inversamente proporcional, com redução da área de cobertura vegetal e aumento do uso da terra pelas atividades agropecuárias. Tais fatores, aliados às características físicas da área, como solos frágeis e altas declividades, sugerem potencial para o surgimento de processos erosivos e assoreamento que impactam o rio Passa-Três. Dessa forma, conclui-se que o uso da terra é incompatível com a capacidade natural da bacia, ocasionando alterações no regime de regularização da bacia hidrográfica do rio Passa-Três, sendo necessária a implementação de práticas de manejo do solo e ações conjuntas com a sociedade para preservar os recursos hídricos na bacia.

Published: April 2024

The object of research is represented by biennial seedlings of Korean pine (Pinus koraiensis Siebold et Zucc.), grown in a forest nursery in the GTS (Mountain Taiga Station) – a branch of the Federal Scientific Center for Biodiversity of the Far Eastern Branch of the Russian Academy of Sciences of Primorsky Krai. The influence of stimulants Zircon, Krezacin, Epin-Extra on the biometric parameters of seedlings was studied. Stimulants are used in the form of root dressing in different concentrations of solutions. The height of the trunks and the length of the roots, the diameter of the root collar, as well as the dry mass are estimated. It was revealed that the use of top dressing in the form of the noted stimulants at a solution concentration of 0.01% provides a better increase in the aerial part of Korean pine. It is also noted that the development of roots is activated. It was found that during the study period, the height was at the level of 8.1 to 12.9 cm, the diameter of the root neck was from 3 to 3.5 mm, the length of the roots was from 10.8 to 14.2 cm, the dry weight was from 1.1 to 1.62 g. An increase in indicators was found (in comparison with the samples of the control group), respectively, by 28.6‑104.8; 30.1‑71.1; 11.1‑29.6 and 57.1‑131.4%. According to the current Rules for Reforestation (Order of the Ministry of Natural Resources of Russia dated December 04, 2020 No. 1014 “On Approval of the Rules for Reforestation, the Composition of the Reforestation Project, the Procedure for Developing a Reforestation Project and Making Changes to It”; hereinafter referred to as the Reforestation Rules), Korean pine seedlings in the Far East reach standard sizes in 2‑3 years. In our experiments, seedlings treated with the growth stimulator Zircon, fed with a solution concentration of 0.01%, reached the age of planting material quality after 2 years.

In arid regions, forest strips are one of the most important natural resources. The use of modern preparations that improve the growth and development of plants will allow the most complete and effective cultivation of planting material and meet the need for various types of forest products. Squat elm (Ulmus pumila L.) has increased resistance to drought, decorative and protective properties. During the experiment, the authors tested a humic fertilizer-a growth biostimulator “Biofulen torfogel”, which contains nitrogen, phosphorus, potassium, humic and fulvic acids, which provide the plant with all the necessary nutrients during active growth. It was revealed that Biofulen torfogel has a positive effect on seedlings of squat elm, increasing their biometric parameters several times in comparison with the control. Weather conditions in 2020 and 2022 were milder, as a result of which the weight of the root and foliage of the studied plants under the wagging of the drug turned out to be higher than in 2021. It is established that the regulation of the time of soaking seeds in the preparation “Biofulen” allows you to get elm seedlings of various sizes.

Published: April 2024

The results of vegetation and field experiments on the influence of moisture conditions on the productivity and feed value of Mageva soybeans are presented. It is established that the conditions of moisture availability are an important factor in regulating the level of symbiotic nitrogen fixation and the production process in soybeans. Increasing the pre-irrigation soil moisture from 40 to 60% PPV (maximum field moisture capacity) can significantly increase crop productivity: yield from 4.11 to 7.64 g/vessel, protein harvesting with seed yield from 8.04 to 16.50 g/vessel, essential amino acids from 5.22 to 10.70 g/vessel or 1.81‑2.05 times; fat collection – from 2.34 to 4.37 g/vessel, or 1.68‑1.85 times, collection of feed units from 28.77 to 53.48 g/vessel or 1.69‑1.86 times. In the field experiment, with optimal heat and moisture availability, the yield is 2.71 t/ha, the level of symbiotic nitrogen fixation reaches 208 kg/ha, which covers 96% of the nitrogen needs of plants. Excessive and especially insufficient moisture supply significantly reduce productivity indicators: yield – by 1.08‑1.84 times, protein collection by 1.14‑1.62 times, collection of essential amino acids – by 1.13‑1.60 times, lysine – by 1.12‑1.61 times, fat collection – by 1.04‑1.42 times, and unsaturated fatty acids – by 1.03‑1.41, collection of feed units – 1.10‑1.80 times, the level of symbiotic nitrogen fixation up to 33‑79% or 1.29‑2.90 times.

Published: April 2024

The subject of the study is reinforced concrete corner retaining walls, widely used in hydraulic engineering construction. Optimization of the shape of the vertical console of corner retaining walls is important to reduce internal forces and increase the stability of structures. When replacing flat panels with spatial structures in the console, bending moments are reduced; the predominant work of structures for compression or stretching allows reducing their thickness due to more efficient use of materials. The purpose of the study is to determine the optimal shape and nature of reinforcement of vertical retaining wall consoles, depending on their height. The study was conducted in the certified software package “LIRA-CAD2021”. Computational models of corner retaining walls with consoles in the form of multi-wave cylindrical shells and folds have been developed. At the junctions of the waves and the edges of the folds, racks are provided, pinched in the ground. Comparative calculations of structures in the software package “LIRA-CAD2021” were performed. The results of calculations are analyzed. Conclusions are drawn on the optimization of the structures of retaining walls with a vertical console in the form of shells and folds. The study showed that with a retaining wall height of up to 3 m, a retaining wall with a console in the form of a multi-wave shell is more rational in terms of material consumption. At a height of more than 3 m, retaining walls with a console in the form of folds with vertical posts at the interface of the faces become rational. For consoles in the form of shells, double reinforcement is recommended with an increase in the area of the reinforcement in the lower part and at the interface areas of adjacent waves. For consoles in the form of folds, double reinforcement is also recommended, but additional reinforcement is required only in the area of the interface of the panels with the foundation plate.
The Effect Of Tax Avoidance On Firm Value With Tax Expert As Moderating Variables
Authors: Nurseto Ian , Bandiyono Agus
Published: April 2024

The company's goals in this modern era have undergone significant changes. The company's focus has changed from focusing on maximizing profit to increasing firm value. Firm value, which is reflected in the value of the company's shares, can grow along with the increase in company profits. Tax, which is an element of development, is seen by companies as one of the factors that determine the company's value. This is a consideration for companies to behave in tax avoidance or not. This study tries to analyze the relationship between tax avoidance by the entity and its firm value and the extent to which the tax expert influences both of these. This study provides several conclusions, i.e., tax avoidance has a negative effect on firm value. These results contradict the initial testing hypothesis where tax avoidance has a positive impact on firm value. The moderating influence, tax experts, don't affect the relationship between tax avoidance and firm value.JEL: D13, I31, J22*
Macroeconomic, Corporate Fundamentals, Systematic Risk on Firm Value: Evidence from Indonesian Manufacturing Sector
Authors: Mappadang Agoestina
Published: April 2024

This paper aims to study the connection between the effect of macroeconomics, corporate fundamentals on systematic risk, and the firm’s value of the Indonesian manufacturing industry listed on the Indonesian Stock Exchange period 2015-2020. A total of 522 object analyses in this study with the purposive sampling method. This paper found that the direction and magnitude of the impact of firm value depend on macroeconomic measurement variables: interest rates, exchange rates, and the company’s fundamental measurement variables: leverage and capital expenditure. The paper also found that the macroeconomic positively affects firm value, and leverage has a significant positive effect on firm value. At the same time, capital expenditure shows different results in response to the firm value, that is, negatively significant. In particular, a systematic risk as a mediating variable becomes a significant and positive driver of macroeconomics and leverage on firm value. However, different results indicate that capital expenditure negatively affects the firm value if mediated by the systematic risk. The implication of this research is beneficial to enable companies and investors to make the right analytical decision in the Indonesian capital market in this pandemic covid-19 situation.JEL: E43, G10, G32
Determinants of green bond premium in the ASEAN market amidst the COVID-19 pandemic
Authors: Oktavio Laurent , Riyanti Ririen Setiati
Published: April 2024

Green bonds as a means of financing instrument for sustainable projects have caught the eyes of investors in recent years. With the growth of the global green bond market exceeding 50% in 2019 (CBI, 2019), green bonds serve as a promising financial instrument for organizations and a promising financial asset for investors. Previous studies have conflicting results in identifying the premium investors pay for investing in green bonds where both a positive and negative premium was observed. This study aims to examine the premium of green bonds issued in Southeast Asia before and during the COVID-19 pandemic from March 2016 to April 2021 by using a two-step regression model. In the first step, by employing a fixed-effect model to 42 green bonds, the results of this study suggest a positive green bond premium before the COVID-19 pandemic and a negative green bond premium during the pandemic. Additionally, this study conducts cross-section regressions to investigate the determinants of green bond premium. The results imply that rating, currency, issue amount, and time to maturity significantly affect the green bond premium.JEL: C23, G12, G14, G20, Q56

Published: April 2024

This study aims to analyze the effect of risk on financial performance and the moderating effect of bank size on the relationship between risk and financial performance. This study uses seven Foreign Exchange National Private Commercial Banks listed on the IDX 2015-2019 as the samples. The analytical method used is a panel data regression model with STATA 16.0 software. Empirical results show that liquidity and credit risk have no effect on financial performance. Market risk has a significant positive effect on financial performance while operational risk has a significant negative effect on financial performance. Bank size  moderate the effect of liquidity and credit risk on financial performance but failed to moderate the effect of market and operational risk on financial performance. These findings imply that national foreign exchange private commercial banks listed on the IDX for the 2015-2019 period should pay attention to the market and liquidity risks as those risks affect banks’ profitability, especially for large banks.

André Bazin’in Sinema Kuramında Hayvanlar: Dil ve Sinematografik Dilin Ayrımında
Authors: Gergöy Adem
Published: April 2024

Sinema ortaya çıktığı yıllarda birçok tartışmayı da beraberinde getirmiştir. Bu tanımlara “gerçeklik” kavramı üzerinden katılan film eleştirmeni ve sinema kuramcısı André Bazin sinema ve yaşam sorusu arasındaki ilişkiye yönelik tespitleriyle öne çıkmıştır. Buna göre fotoğrafın ve sinemanın ortaya çıkması sanat tarihindeki “mimesis” sorununu da ortadan kaldırmıştır. Zira fotoğraf ve sinema sahip olduğu ontolojik olanaklar sayesinde nesne ve imgesi arasındaki “mesafeyi” kapatmıştır. Bazin bu bağlamda sinemayı fiziksel gerçekliği kurtaran ve insanın merkezî konumunu yerinden eden bir fenomen olarak görmüştür. Bu yaklaşım aynı zamanda “insan-merkezci” düşüncenin karşısında güçlü bir konum almaktadır. Başka bir deyişle Bazin’in, “gerçeklik” kavramı özelinde öne sürdüğü “fotografik imgenin ontolojisi” aynı zamanda insanın, “metafizik mevcudiyeti”ne karşı eleştirel bir tutum içermektedir. “Varlık” sorusunu merkeze alan bu yaklaşım hayvan konusunu da tartışmak için bir anahtar sunmaktadır. Bu makale Bazin’in sinemaya ilişkin bu tanımını hayvan temsili açısından tartışmaya açıp bu sinema kuramının hayvanlar hakkında ne tür etik-politik olanaklar sunabileceğini araştırmıştır. İnsanın metafizik kurgusu Jacques Derrida’nın belirttiği üzere dilin “logosantrik” (söz merkezci) kökenlerinden beslenmektedir ve bu kavramın çıkış noktası ise “insan-hayvan ayrımı” dır. Buna göre dil basitçe bir iletişim aracı olmayıp insanın hayvanlar karşısındaki eylemlerinin de çıkış noktasıdır. Sinemayı fiziksel gerçekliği kurtaran özgün bir dil olarak gören Bazin bu açıdan insan-hayvan ayrımının ontolojik ve etik-politik yönlerine ışık tutmaktadır. Bu bağlamda Bazin’in “gerçeklik” kavramı “insan-merkezli” düşüncenin temel kavramlarından olan “logosantrizm”i dışlayan bir zemin üzerinde kurgulanırken hayvanlar için temsil ötesi bir varoluş alanı açmaktadır.

Research Results. The issue of structure and content improvement of the educational and training process at various stages of the long-term training of athletes is not new, but it is clearly urgent. That is why at the current stage of hand-to-hand combat (HTH) development, it is especially important to solve the issue of the training program improvement at the basic training stage, which is highly decisive for the athletes` choice of the discipline and type of program. Conclusions. It has been established that the specialized basic training stage is decisive for the future athletes` professional preparation, the choice of the discipline and the type of program which they will use in the future. The lack of program recommendations at sports schools` documents that are based on general theoretical provisions and tasks, leads to errors in the training procedure construction and a decrease in its effectiveness. Building an optimal training athlete` program is possible on the basis of correcting and changing sports schools` training program, applying the latest methods, tools and management technologies, taking into account the features that characterize the third stage of multi-year improvement.
