Background
Smoking and alcohol use frequently co-occur and are the leading causes of preventable death in sub-Saharan Africa (SSA) and are common among people living with HIV (PLWH). While alcohol use has been shown to be associated with reduced adherence to antiretroviral treatment (ART), which may affect HIV viral suppression, the independent effect of smoking on HIV outcomes in SSA is unknown. We aimed to 1) describe the prevalence of current smoking and correlates of smoking; 2) assess the association of smoking with viral suppression, adjusting for level of alcohol use; 3) explore the relationship between smoking and CD4 cell count <350 cells/mm3, among participants who are virally suppressed.

Methods
We analyzed data from the Drinkers Intervention to Prevent Tuberculosis (DIPT) and the Alcohol Drinkers’ Exposure to Preventive Therapy for TB (ADEPTT) studies conducted in Southwest Uganda. The studies enrolled PLWH who were on ART for at least 6 months and co-infected with latent tuberculosis and dominated with participants who had unhealthy alcohol use. Current smoking (prior 3 months) was assessed by self-report. Alcohol use was assessed using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C, modified for prior 3 months) and phosphatidylethanol (PEth), an alcohol biomarker. We used logistic regression to estimate the cross-sectional association between smoking and lack of virological suppression (≥40 copies/ml), adjusting for level of alcohol use and other covariates, and to examine the association between smoking and CD4 cell counts among PLWH with viral suppression.

Results
Of the 955 participants enrolled from 2017 to 2021 who had viral load (VL) results, 63% were men, median age was 40 years (interquartile range [IQR] 32–47), 63% engaged in high/very high-risk alcohol use (AUDIT-C≥6 or PEth≥200 ng/mL), and 22% reported smoking in the prior 3 months. Among 865 participants (91%) with viral suppression and available CD4 count, 11% had a CD4 cell count <350 cells/mm3. In unadjusted and adjusted analyses, there was no evidence of an association between smoking and lack of virological suppression nor between smoking and CD4 count among those with viral suppression.

Conclusions
The prevalence of smoking was high among a study sample of PLWH in HIV care with latent TB in Southwest Uganda in which the majority of persons engaged in alcohol use. Although there was no evidence of an association between smoking and lack of virological suppression, the co-occurrence of smoking among PLWH who use alcohol underscores the need for targeted and integrated approaches to reduce their co-existence and improve health.
“Rus', You are but a Kiss in the Cold!” (1921) by V. Khlebnikov: Text as a Combinatory Model / Dynamic Construction
Authors: Tyryshkina Tyryshkina Elena 
Published: March 2024

The paper is devoted to analysis of the poem by Velimir Khlebnikov “Rus', you are but a kiss in the frost!” (1921) as part of a study of transformation of the sonnet genre in the poet’s verses. Velimir Khlebnikov elaborates his version of a lyrical story of ‘a kiss in the frost’, originating from the poem by Alexander Pushkin “Winter. What do we do in the village?…” (1829). The love scene is represented as a natural phenomenon, embedded not only in the winter landscape but also in the Universe. There are no persons in the Nature’s integrity, and the couple of lovers are designated only by demonstrative pronouns. The tension of feelings (“the lightning kiss”) is but one of the manifestations of the Elements. The phenomenon of a lightning as a “potentially energy-embracing symbol” has a conceptual character in Khlebnikov’s perception of the world, is both the “primordial image” of the world and the principle of universal unity, which has already been noted by the eminent researchers’ of Khlebnikov’s works. From the formal viewpoint, the text is a special variant of structural deformity and overcoming it, which is directly related to the idea of accumulation of energy, explosion, and return to tranquility. The poem is characterized by increased expression of the arrangement of its sounds; alliteration of the occlusive, fricative, and sonorant sounds, their combinations, and paronymic attraction create the effect of a special energy of sound-making. The rhythmic arrangement of the text “deceives” the reader’s expectations: fast shifts and transitions from one meter to another (polymetry in the first stanza), occasional caesuras in the first, fourth, and ninth verses, an enjambement in the seventh and eighth verses: breakage of the seventh verse, when the verb “would [swiftly] outline” starts a line, visualizing the movement of a lightning. Structural deformities are settled in the final — the last verse is written in a classical iambic tetrameter. Graphically, the lyrical text is a combinatory dynamic model which may vary in terms of strophic division, the “headless” sonnet, preserving the characteristics of the Italian sonnet, dominates. The mechanism of cohesion is ensured by all the levels of the artistic whole, and the genre of the sonnet is a harmonizing form, balancing the structural instability of the text.

Published: March 2024

In recent years, there has been a persistent search for new methods and technologies for cultivating individual crops in order to increase their productivity and improve product quality. New methods of pre-sowing seed treatment with biological stimulants are increasingly being introduced, increasing not only crop yields, but also changing (increasingly) the content of important nutrients (proteins, fats, carbohydrates, oils, and others). Despite the rapid development of chemistry and the growth in the number of new highly effective drugs of biotechnological and synthetic origin, plants continue to occupy a significant place as a growth stimulator of agricultural crops.
The aim of the work is to evaluate the effect of poplar extract on the growth and development of white cabbage.
Tasks: to investigate the qualitative composition of the aqueous extract of poplar buds; to establish the growth-stimulating activity of the extract of balsamic poplar buds in relation to the seeds of white cabbage.
Methodology and scientific approaches: in the course of the work, experimental studies were carried out on the extraction of natural compounds of balsam poplar buds, evaluating the effectiveness of the balsam poplar bud extract on the growth and development of white cabbage.
Results and conclusions: in the composition of the aqueous extract of poplar buds, such classes of compounds as flavonoids, tannins, coumarins, saponins, amino acids, phenolic acids, polysaccharides were identified; the use of poplar bud extract had a significant impact on morphogenesis, physiological and biochemical parameters, and the productivity of white cabbage of the "Gift" variety.
OPTIMIZATION OF THE METHOD OF QUANTITATIVE DEFINITIONS OF FLAVONOIDS IN THE RAW MATERIALS OF "MENYANTHIDIS TRIFOLIATAE LEAVES"

The aim of the study is to optimize the methodology of quantitative determination of flavonoids in the leaves of Menyanthidis trifoliatae. In official medicine, the leaves of Menyanthidis trifoliatae are used for anorexia and dyspeptic disorders.
In the current regulatory documentation (State Pharmacopoeia of the Russian Federation), it is proposed to evaluate the quality of raw materials by the content of the amount of flavonoids in terms of rutin using spectrophotometry. This technique is based on the ability of flavonoids containing free aromatic hydroxyl groups to form colored products with diazotized sulfanilic acid. The disadvantage of this technique is the long and time-consuming stage of cleaning raw materials from certain groups of lipophilic substances, which can also react with diazotized sulfanilic acid to form colored products.
We have proposed a selective method for the quantitative determination of flavonoids in the herb trifoliate by the method of spectrophotometry in terms of rutin. The technique is based on the ability of flavonoids to form stable colored complexes with aluminum chloride. We have selected the optimal conditions for extraction and complexation reaction of aluminum chloride with flavonoids of M. trifoliatae extract. The proposed method has been validated and is suitable for use in an analytical laboratory.

Published: March 2024

Abstract
In this study, we present a variational multiscale stabilized finite element method for steady-state incompressible fluid flow under magnetic forces. In particular, an algebraic approach of approximating the subscales has been considered, and then, the stabilization parameters are derived using Fourier analysis. The proposed scheme is used to trace the blood flow dynamics in complex arterial vessels under multiple pathological conditions. We examine the pressure and stress distribution in addition to the flow pattern to assess the criticality of the diseased condition.
Assessing the impact of information-induced self-protection on Zika transmission: A mathematical modeling approach
Authors: Manisha  , Nidhi  , Kumar Anuj 
Published: March 2024

Abstract
As per the World Health Organization’s (WHO’s) suggestions, personal protection via adopting precautionary measures is one of the most effective control aspects to avoid Zika infection in the absence of suitable medical treatment. This personal protection further can be enhanced and explored by propagating information about disease prevalence. Therefore, in this study, we wish to see the effect of information on Zika transmission by formulating a compartmental mathematical model that quantifies the effect of an individual’s behavioral response as self-protection due to information. Furthermore, the basic reproduction number was calculated using the next-generation matrix technique. The model analysis was carried out to determine the local and global stability properties of equilibrium points. In addition, the model shows the occurrence of forward bifurcation when the reproduction number crosses unity. To understand the impact of various model parameters, we conducted a sensitivity analysis using both the normalized sensitivity index and the partial rank correlation coefficient methods. Moreover, we performed numerical simulations to assess the influence of important parameters on the model’s behavior for Zika prevalence. Our study accentuates that as information-induced self-protection increases, the prevalence of Zika infection will be at a very minimum level, and this observation is in line with WHO suggestions.

Published: March 2024

Abstract
To sustain the life of flexible pavement materials, the quality of the binder needs to be modified and improved. The purpose of the current research is to investigate the optimum mechanical performances, Marshall characteristics, and moisture damages of hot asphalt mixtures containing nano-clay (nC) additives. Three nominated contents of nC additives of 3, 5, and 7% of the hot asphalt weight were combined by a shear blender at 4,000 rpm for 45 min at 150 ± 5°C. Significant mechanical tests were carried out to estimate the modified asphalt mixture characteristics, such as Marshall stability and moisture susceptibility. Mechanical test results showed that the use of nC as an additive was suitable for enhancing the main characteristics of hot asphalt mixes. Generally, it was found that the indirect tensile strength ratio and stability values of the asphalt mixtures containing 3, 5, and 7% of nC were improved by 8, 23, and 24% and 12.5, 40, and 52%, respectively. The 7% nano-clay additive showed superior values of tensile strength and stability as compared with all asphalt mixtures (i.e., 94% and 15.8 kN, respectively).
Examination of archaeological bronze parts using micro-computed tomography and metallography
Authors: Haubner R. , Strobl S. 
Published: March 2024

Abstract
Archeological finds, such as old coins among which some show signs of corrosion, are, in general, unique pieces even though several copies exist of individual types. Subferrati, Roman coins with an iron core and a bronze coating, for instance, could be examined by conventional computed tomography (CT). The CT image allows an easy distinction of corrosion products, metallic iron, and the bronze so that appropriate sections could be selected from the images for metallography.
The micro-CT technology even allows examining smaller archaeological objects to get an overview. The resolution of the micro-CT is a function of the object size and lies between 5 and 10 μm. The following metallographic examinations are intended to characterize the microstructure. Apart from these examinations, SEM analyses may also be performed on the sections.
Different bronze pieces from cremation and inhumation burials were examined. Micro-CT provides a well recognizable contrast between corrosion products and the metallic bronze.
If several similar objects exist, micro-CT examinations allow a decision to be made on which parts are suitable for metallographic analyses and which are not.
AI recommendations’ impact on individual and social practices of Generation Z on social media: a comparative analysis between Estonia, Italy, and the Netherlands
Authors: Arkhipova Daria , Janssen Marijn 
Published: March 2024

Abstract
Social media (SM) influence young adults’ communication practices. Artificial Intelligence (AI) is increasingly used for making recommendations on SM. Yet, its effects on different generations of SM users are unknown. SM can use AI recommendations to sort texts and prioritize them, shaping users’ online and offline experiences. Current literature primarily addresses technological or human-user perspectives, overlooking cognitive perspectives. This research aims to propose methods for mapping users’ interactions with AI recommendations (AiRS) and analyzes how embodied interactions mediated by a digital agent can lead to changes in social and cultural practices. For this, this work proposes a comparative analysis of central practices evoked by AI recommendations-mediated communication on SM among users in Italy, Estonia, and the Netherlands in the age category 18–26 years old. The data used in the comparative analysis was collected via semi-structured interviews and elaborated based on cognitive psychology and semiotics. This research highlights the contextual significance of AI recommendations as a mediator in creating new communication practices. Findings confirm that young adults often choose practices that would enhance their digital representations according to AiRS’ dominant patterns and categories. AiRS impacts individual interpretations and practices and can further affect social and cultural levels.

Published: March 2024

Abstract
To improve the lubrication performance of friction pairs to the greatest extent and obtain the best microtexture, a new compound microtexture with multiple shapes is proposed, and the influence of compound texture arrangement on the lubrication performance of friction pairs is studied. Based on the Reynolds equation, a numerical calculation model of compound microtexture friction pairs under the condition of hydrodynamic lubrication is established, and equations are solved using the finite difference method. Considering the influence of surrounding texture and cavitation effect, the influence of compound texture arrangement and shape on the lubrication performance of friction pair is studied. The results show that compared with the single microtexture, the compound texture with two different shapes can influence each other during the lubrication process, which can better improve the average pressure in the microtexture region, reduce the friction coefficient, and obtain the stronger hydrodynamic effect and better lubrication performance. The circumferential parallel arrangement of compound microtexture can produce the stronger hydrodynamic effect and improve the performance of the friction pair.

Published: March 2024

This paper aims to describe the local wisdom values of the Tuk Sikopyah Ritual in Serang Village, explain their inheritance, and analyse the water management in overcoming drought. The research employed a mixed method. The qualitative method was used to examine the data dealing with explaining the local wisdom values of the Tuk Sikopyah Ritual and the ways of their inheritance to the younger generation; whilst the quantitative method was to calculate the usage of the water in meeting daily water needs of Serang community. It was found that seven kinds of noble values are practised in the Tuk Sikopyah water-taking ritual. The seven noble values are concerned with the existence, utilization, and preservation of the Tuk Sikopyah water spring. The caretaker collaborates with the clerics and local government to teach and inherit the local wisdom values in the Tuk Sikopyah water-taking ritual. The calculation showed that only around 72.80% of the Tuk Sikopyah water debit (calculation in the dry season) were used to fulfil the daily need of the community of Serang Village.
