Predictability reduces event file retrieval
Authors: Schmalbrock Philip , Hommel Bernhard , Münchau Alexander , Beste Christian , Frings Christian
Published: December 2022

There is growing consensus that stimulus–response bindings (event files) play a central role in human action control. Here, we investigated how the integration and the retrieval of event files are affected by the predictability of stimulus components of event files. We used the distractor–response binding paradigm, in which nominally task-irrelevant distractors are repeated or alternated from a prime to a probe display. The typical outcome of these kinds of tasks is that the effects of distractor repetition and response repetition interact: Performance is worse if the distractor repeats but the response does not, or vice versa. This partial-repetition effect was reduced when the distractor was highly predictable (Experiment 1). Separate manipulations of distractor predictability in the prime and probe trial revealed that this pattern was only replicated if the probe distractors were predictable (Experiment 2b, 3), but not if prime distractors were predictable (Experiment 2a). This suggests that stimulus predictability does not affect the integration of distractor information into event files, but the retrieval of these files when one or more of the integrated features are repeated. We take our findings to support theoretical claims that integration and retrieval of event files might differ concerning their sensitivity to top-down factors.

The article deals with the problem of reducing the loss of silver during the deleading of fine kiln dust from the nickel production of the Kola MMC. It has been shown that an increase in the degree of silver recovery is achieved by using sodium sulfate solutions or filtrates of water leaching of dust purified from selenium and tellurium as sulfate-containing reagents at the stage of lead sulfate precipitation. This ensures the subsequent separation of silver and lead by sulfite leaching and the production of selective concentrates.

Deep eutectic solvents are potentially promising media for metals from various materials, including rocks. Of particular interest is the possibility of extracting rare earth elements, the demand for which is growing due to the expansion of their consumption. However, there are little data on the solubility of rare earth element compounds in deep eutectic. The purpose of this work is to study the process of dissolution of compounds of rare earth elements, in particular lanthanum hydroxide, in deep eutectic solvents. The dynamics of the dissolution of lanthanum hydroxide in deep eutectic solvents based on choline chloride and malonic, malic, tartaric and citric acids, was investigated. It was found that the concentration of lanthanum when using a deep eutectic solvent with tartaric acid almost immediately reaches a plateau, with malonic and malic acid it gradually decreases, and with citric acid it increases. The highest concentration of lanthanum is achieved by using a mixture of choline chloride with citric acid — 10.9 g / l.
Deep eutectic solvents in chemical analysis. Opportunities and limitations
Authors:   Saint Petersburg State University, Shishov Andrey Yu.
Published: December 2022

Deep eutectic solvents (DES) are a mixture of two or more components, the melting point of which is significantly lower than the melting points of the starting materials. Environmental safety, ease of preparation in the laboratory, and low cost of DES have led to the fact that they have recently found increasing use in analytical chemistry. DES are most widely used in separation and concentration methods as effective extractants for the isolation of both hydrophobic and hydrophilic analytes from various objects of analysis. However, the possibility of their application is not limited to use only as extractants. This paper presents the classification of DES according to the criterion of their stability in the aqueous phase, the possibilities and examples of the separation of analytes from liquid, solid-phase and gaseous samples into the DES phase are also considered. In addition, various schemes for the implementation of liquid microextraction based on the principles of the formation and destruction of DES and methods for their automation based on the principles of flow methods are considered. The possibility of using eutectic compounds as effective dispersants in dispersive liquid extraction has been demonstrated. The possibility of simultaneous use of eutectic solvents both as extractants and as reagents for the derivatization of analytes to convert them into an analytical form directly in the extraction process, is shown. The possibility of modification of various sorption materials with eutectic solvents for the method of solid-phase microextraction, is shown. The paper touches upon the problems and limitations associated with the use of DES in chemical analysis, as well as the main prospects for its development.

Published: December 2022

During the continued isolation of different bacteria from highly diverse, low human activity environments in Ghana and the subsequent characterization and biological activity studies of their secondary metabolites, we found both Gram-positive and Gram-negative Bacillus strains to be ubiquitous and widespread. One of such strains, the Ghanaian novel Bacillus sp. strain DE2B was isolated from rhizosphere soils collected from the Digya National Park in Ghana. Chromatographic purifications of the fermented culture extract of the strain DE2B, led to the isolation of a cyclic lipopeptide, digyalipopeptide A (1). Using 1D and 2D NMR data, mass spectrometry sequence tagging, advanced Marfey’s analysis, and the GNPS molecular networking we solved the full structure of digyalipopeptide A (1). We found that compound 1 is a member of a somewhat homologous series of peptides produced as a mixture by the strain containing the same amino acid sequence in the cyclic peptide backbone but differing only by the length of aliphatic fatty acid side chains. When tested against Trypanosoma brucei subsp. brucei strain GUTat 3.1 and Leishmania donovani (Laveran and Mesnil) Ross (D10), digyalipopeptide A (1) gave IC50 values of 12.89 µM (suramin IC50 0.96 µM) and 4.85 µM (amphotericin B IC50 4.87 µM), respectively. Furthermore, digyalipopeptide A (1) produced IC50 values of 10.07 µM (ampicillin IC50 0.18 µM) and 10.01 µM (ampicillin IC50 1.53 µM) for Staphylococcus aureus and Shigella sonnei, respectively. The selectivity and toxicity profile of compound 1 was investigated using normal cell lines, macrophages RAW 264.7. When tested against normal macrophages, compound 1 gave an IC50 value of 71.32 μM. Selectivity indices (SI) were obtained by calculating the ratio of the IC50 in RAW 264.7 to the IC50 in the respective microbe and neglected parasite. In the presence of RAW 264.7 cell lines, compound 1 was particularly selective towards Leishmania donovani (Laveran and Mesnil) Ross (D10) with an SI value of 14.71. The bioactivity studies conducted confirm the role of these cyclic lipopeptides as defense chemicals in their natural environment and their ability to be biologically active across different species.

Published: December 2022

An operationally simple, metal-free approach has been described for the synthesis of pyrazole tethered thioamide and amide conjugates. The thioamides were generated by employing a three-component reaction of diverse pyrazole C-3/4/5 carbaldehydes, secondary amines, and elemental sulfur in a single synthetic operation. The advantages of this developed protocol refer to the broad substrate scope, metal-free and easy to perform reaction conditions. Moreover, the pyrazole C-3/5 linked amide conjugates were also synthesized via oxidative amination of pyrazole carbaldehydes and 2-aminopyridines using hydrogen peroxide as an oxidant.

Free radicals are molecules with reactive unpaired electrons which are produced during cell metabolism and create the oxidative stress inside tissue resulting in tissue damage. The aim of the present study was qualitative and quantitative phytochemical screening, determination of total phenolic and total flavonoid content, and free radical scavenging activity of different parts of ethnomedicinally used Rubus ellipticus Sm. plant. Root, stem, and leaves of Rubus ellipticus Sm. were collected from Annapurna Rural Municipality, Kaski, Western Nepal. Ethyl acetate and ethanol extracts of the plant parts were obtained by subsequent maceration process. The phytochemical screening of most of the extract showed the presence of phenols, carbohydrates, flavonoids, and glycosides. The ethanolic extract of stem showed the higher phenolic content with the value of 343.75 ± 2.21 µg GAE/mg. Ethanolic extract of stem had the highest amount of flavonoid content (1563.17 ± 10.79 µg QE/mg of extract), whereas all the ethyl acetate extracts of root, leaves and stem showed comparable flavonoid content. Ethanolic extracts of leaves showed potent DPPH free radical scavenging activity with IC50 value of 5.03µg/ml while ethyl acetate extract of stem showed the maximum free radical scavenging properties. The result depicted that the ethanolic extract of Rubus ellipticus Sm. showed the potent antioxidant activity by scavenging free radicals.

Cengiz Yörük, Cumhuriyet sonrası hikâye yazarlarındandır. Üç hikâye kitabı, bir de şiir antolojisi bulunur. Kısa bir yazı hayatı vardır. 1950’lerde yazı hayatına başlamıştır. Son eseri ise 1967 tarihlidir. Ödüllü, başarılı bir yazar olmasına rağmen Cengiz Yörük’ün ismi, edebî kamuda pek bilinmez. Bazı edebiyat ansiklopedilerinde, yazar sözlüklerinde adına denk gelinse de hakkında fazla bilgi yoktur.

Üzerine yapılmış herhangi bir araştırmanın olmayışı, eserlerinin şimdiye dek bir incelemeye konu edilmeyişi bu makalenin yazılmasının temel sebebidir. Makalede, Cengiz Yörük hakkında tespit edilebilenler ortaya konacak ve hikâye kitaplarının tamamı ele alınacaktır. Bu vesile ile âdeta unutulmaya yüz tutmuş yazarın edebî varlığı gündeme getirilecektir.

ГРАЖДАНСКО-ПРАВОВОЙ ОТВЕТСТВЕННОСТИ
Authors: Александрова Л. Ю. , Флерова Д. А.
Published: December 2022

В юридической науке феномен ответственности часто исследуется под ракурсом наказуемости и ретроспективности. В статье раскрыта сущность и цель ответственности, отличия позитивной ответственности от негативной. Важным для гражданского права понятием и юридически значимой категорией является гражданско-правовая ответственность. Авторами проведен сравнительный анализ полярных точек зрения относительно гражданско-правовой ответственности. Рассмотрена ее сущность как сложного правового явления и вида юридической ответственности, как охранительного правоотношения и средства защиты гражданских прав и влияния на нарушителей. Обозначены объективные условия привлечения лица к гражданско-правовой ответственности, ее задачи, признаки и особенности, связанные с природой гражданских правоотношений. Выявлена связь между ними (особенностями) с принципами (законности, справедливости, неотвратимости и целесообразности мер воздействия, др.) и функциями (защитная, регулятивная, компенсационная, профилактическая) гражданско-правовой ответственности. Сделан вывод о том, что понятия «основание» и «условие» ответственности не идентичны; в практической деятельности необходимо учитывать ее общие и специфические особенности.

В работе рассматривается кэшбек-сервис «LetyShops», а также мероприятия по оптимизации маркетинговых стратегий для выстраивания долгосрочных и постоянных коммуникаций с потребителями в условиях цифровизации глобального торгового рынка и развития интернет-маркетинга. Большинство современных компаний старается больше фокусироваться на клиентах, тем самым, становится клиентоцентричными. Современное общество живет в мире Интернета, где клиентам доступна практически любая информация, поэтому успешно конкурировать между собой могут только те компании, которые ставят клиента в центр своей деятельности и развивают маркетинг лояльности. Программа лояльности – это эффективная система поощрения активных клиентов. Она помогает компаниям удерживать постоянных покупателей или пользователей, ведь именно они приносят основную прибыль. Чем выше уровень лояльности, тем больше вероятность, что человек останется с брендом на долгое время. Маркетинговые исследования показывают, что удержание старых покупателей обходится гораздо дешевле привлечения новых. Программами лояльности для удержания постоянных покупателей и привлечению новых пользуются банки, интернет-магазины, кэшбек-сервисы, платежные системы и все остальные компании, предлагающие свои товары или услуги.

Gamma Cas Stars as Be+White Dwarf Binary Systems
Authors: Gies Douglas R. , Wang 王 Luqian 璐茜 , Klement Robert
Published: December 2022

The origin of the bright and hard X-ray emission flux among the γ Cas subgroup of B-emission line (Be) stars may be caused by gas accretion onto an orbiting white dwarf (WD) companion. Such Be+WD binaries are the predicted outcome of a second stage of mass transfer from a helium star mass donor to a rapidly rotating mass gainer star. The stripped donor stars become small and hot white dwarfs that are extremely faint compared to their Be star companions. Here we discuss model predictions about the physical and orbital properties of Be+WD binaries, and we show that current observational results on γ Cas systems are consistent with the expected large binary frequency, companion faintness and small mass, and relatively high mass range of the Be star hosts. We determine that the companions are probably not stripped helium stars (hot subdwarf sdO stars), because these are bright enough to detect in ultraviolet spectroscopy, yet their spectroscopic signatures are not observed in studies of γ Cas binaries. Interferometry of relatively nearby systems provides the means to detect very faint companions including hot subdwarf and cooler main-sequence stars. Preliminary observations of five γ Cas binaries with the CHARA Array interferometer show no evidence of the companion flux, leaving white dwarfs as the only viable candidates for the companions.
