Authors: Mirzajanov M. A. , Ergashev M. M. , Otakulov B. A.
Published: August 2023

The article describes the results of theoretical and experimental studies to identify the relationship between the parameters of the steam structure and thermal conductivity of ashclaydite. The correlation dependences of the thermal conductivity coefficient of ash-claydite on its parameters of the stream structure have been established. The analysis of these works shows that the thermal conductivity of lightweight concrete depends on the type of porous aggregate, on the direction of the heat flow in relation to the layering of the concrete, the average temperature at which heat transfer occurs, the average density and moisture content of the concrete. In most works, a significant effect of the steam structure of the aggregate on the thermal conductivity of concrete is noted.

Published: August 2023

The article provides a detailed analysis of well-known studies, which allow considering the work of the structure together with the base under dynamic influences, adequate replacement of an infinite base with a finite one using non-reflecting conditions on the boundary of the finite region, well-known methods for assessing the behavior of a structure under impact. A mathematical model, method, and algorithm were developed to evaluate the dynamic behavior of earth dams together with the base under shock impact using non-reflective conditions based on Rayleigh waves on the boundaries of the finite area of the base. To simulate a dynamic process, the principle of virtual displacements is used, taking into account the viscoelastic properties of the material. The solution to the problem is conducted by the finite element method and the Newmark method. The dynamic behavior of earth dams, together with the base, is studied, considering non-reflecting conditions under explosive impacts that arise not far from the structure. It was established that during the period of wave travel, a non-synchronous movement of individual parts of the dam occurs, damped due to the wave entrainment of energy and the viscoelastic properties of the material. It was revealed that the maximum principal stresses σ1 occur in the lower part of the upper slope of the dam and gradually spread along the entire dam; the maximum principal stresses σ2 are reached near the foot of the dam and, as the wave propagates, they move along the base directly behind the wavefront; the maximum values of shear stress σ12 are reached on the surface of the upper slope, first at the foot of the dam, then over the entire surface of the slope.

The article presents the results of field research to determine the physical and chemical composition of sediments in the Langar and Kalkama reservoirs in the Kashkadarya region. Data on the volume of floods in Langar, Kyzylsuv, Kalkama, and Dehkanabad flood reservoirs in 2015-2021 were presented, and it was noted that in Langar in 2019, there were 3 times more floods than in 2015. The granulometric content of turbid sediments in the middle part of the Langar flood reservoir is 29.93% from 0.005-0.002 mm, 21.36% from 0.01-0.005, 21.36 from 0.05-0.01 mm, 25.35% from 0.1-0.05, 0.25-0.1 mm to 0.6%, 0.5-0.25 mm to 0.8%, 1.0-0.5 to 0.6%, i.e., the amount of particles smaller than 0.05 mm reaches 98%. This figure is 94-95% in front of the flood reservoir's upper and water discharge part. It is justified that mud from the Langar flood reservoir can be used as a building material in brick factories due to its high viscosity, and mud from the Kalkama flood reservoir can be used in construction as fine sand due to its low viscosity.

General algorithm for optimal control of moving industrial robots
Authors: Muhamediyeva D. T. , Fozilova M.
Published: August 2023

Control of robots in changing conditions is complex, and its main reason is, firstly, that the robot changes its manipulative behavior concerning the influence of the external environment, and secondly, that it does not have a clear model of motion. If the motion model is not clear, the control model will not be clear, and it will be difficult to determine the control parameters of the robot. Therefore, to overcome these shortcomings, the article presents a model of the motion of robots moving in changing conditions using mathematical methods and an algorithm for optimal control based on it.

Published: August 2023

Tribological components cost just a fraction of the whole spacecraft, but they often lead to failures that partially or completely disrupt the spacecraft. Mechanical components used in space applications have to withstand extreme and severe environmental conditions such as very high or very low cryogenic temperatures, high vacuum, corrosive elements and radiation. MoS2 is the most widely used lubricating material in space applications. It possesses a lamellar structure with strong covalent bonds within layers and simultaneously weak van der Wall’s interlayer bonds, resulting in easy shearing of the crystals in the direction parallel to the basal planes, hence acting as a good solid lubricant.

In this research, a thin film nano scale coating of MoS2 was deposited on steel using Physical Vapour Deposition (PVD). The PVD technique used was the RF magnetron sputtering process. Material characterization was performed using X-Ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) and Raman spectroscopy. According to the results, the developed MoS2 nano coatings have a polycrystalline structure with basal planes that are oriented perpendicular to the substrate surface.

Authors: Negmatov Soyibjon , Abed Nodira , Ulmasov Tulkin , Khaminov Burkhon
Published: August 2023

This article is devoted to the study of thermodynamic compatibility and structural characteristics of interpenetrating polymer systems (IPS) based on thermosetting and thermoplastic polymers for the production of vibration-damping and sound-absorbing composite polymer materials for machine-building purposes. IPS based on epoxy polymer and polyurethane is calculated according to the well-known Flory-Scott theory at a temperature of 373 K to obtain thermodynamic compatibility of the components of the mixture. Studies have established that between the macromolecules of homopolymers that make up the system, a donor-acceptor mechanism of covalent bonding occurs due to an unshared electron of the nitrogen atom and a cross-linked structure of interpenetrating polymer systems is formed, due to the thermodynamic compatibility of the components. The studies determined that at a temperature of 330 K, the coefficient of mechanical losses has a maximum corresponding to the relaxation process associated with the segmental mobility of the chain and the dynamic modulus of elasticity of the composition monotonically decreases with increasing temperature. The maximum vibration-absorbing properties based on epoxy and polyurethane polymers can be obtained at their ratio of 65:35.

Authors: Wicaksono Anggit Grahito , Rahman Ifa Hanifa
Published: August 2023

Every student needs to have learning and innovation skills, media, information, and technology literacy, as well as life skills so they can work and survive in the 21st century. Reading literacy skill is required for developing 21st-century life skills. According to empirical data from the PIRLS test in 2011 and the PISA test in 2018, Indonesian students’ reading literacy skill is still subpar worldwide. High reading literacy skill is required of prospective elementary school teachers. Utilizing a discovery learning approach that strengthens prospective elementary school teachers and students reading literacy skills can help reduce these issues. The two main objectives of this study are: 1) to profile the reading literacy skill of prospective elementary school teachers based on the Minimum Competency Assessment and 2) to analyze the effectiveness of implementing the discovery learning model on prospective elementary school teachers’ reading literacy skill. The research method used is a mixed method with a sequential explanatory design that sequentially combines quantitative and qualitative research methods. The results showed that: 1) based on the Minimum Competency Assessment, prospective elementary school teachers’ reading literacy profile was still relatively low (i.e., average score: 54.03, average score for each indicator—finding information, understanding, evaluating and reflecting: 48, 51.8, and of 56.3 respectively); 2) based on the average score of the prospective elementary school teachers’ reading literacy skill before and after the implementation of discovery learning model (54.03 and 72.18 respectively), the implementation of the discovery learning model is effective in improving the reading literacy skills of prospective elementary school teachers who are included under the moderate criteria. This outcome is a result of the integration of the discovery learning model of each syntax training with reading literacy activities, which stimulates students’ reading literacy skills.

Sex-based Learning Approach: Innovation in Teaching English Pragmatics in Single-sex Education
Authors: Arifuddin Arifuddin , Nurtaat Lalu , Amin Muhammad
Published: August 2023

What approach is applied in teaching English in single-sex education (SSE) and Islamic boarding schools in particular? Some studies report that the language proficiency of Islamic Boarding School students remains unimproved. Although it is apparent that SSE makes teachers apply instructional strategies more readily and effectively than in mixed-sex groupings, the suitability of approaches or methods applied by English language teachers in Islamic Boarding Schools remains unanswered. The order of the male’s factors affecting listening difficulties: Speaker, Content, and Listener (Potential for Men’s Islamic Boarding Schools), and female; Listener, Speaker, and Content (Potential for Women’s Islamic Boarding Schools) (Potential for Women’s Islamic Boarding School), and mixedsexes or co-education (Speaker, Listener, and Content) (Potential for Public Schools) potentially answers the phenomenon. Pedagogically, the orders of sex-based factors affecting listening difficulties are potentially applied as an innovative approach to the pragmatics of pedagogy in SSE, particularly in Islamic religious schools in which socio-cultural and religious content are the priority. Lack of direct communicative interactions with different sexes and limited exposure to the real situation of language use might lead to difficulty in pragmatic understanding. A preliminary prospective solution is available. The santri or santriwati need not visit hotels or tourist objects to improve their auditory pragmatic understanding. As another alternative, the students may read “Pragmatics-based Listening for the TOEFL: Innovation in Independent Learning.” English teachers are suggested to try to apply a gender-based listening approach in English language teaching. Finally, a moral message, “Do not let Islamic boarding schools think alone!”.

Framing Covid-19 reporting in the Macau Daily News using metaphors and gain/loss prospects: a war for collective gains
Authors: Wang Vincent X. , Chen Xi , Lim Lily , Huang Chu-Ren
Published: August 2023

This study investigates the use of metaphors and the prospect of gain/loss conveyed in the coverage of the pandemic in a leading conventional news outlet in Macau. We discovered that war metaphors have predominantly been used in reports in the Macau Daily News, and have identified three sets of lexical expressions used in these metaphors. The main themes conveyed by the war metaphors include describing the gravity of the situation, communicating anti-pandemic measures, and urging the public to participate in anti-pandemic efforts. In addition, the persuasive messages contained in the appeals for joint action are examined in terms of gain/loss frames and collectivistic versus individualistic appeals. We argue for an analytical framework that encompasses both conceptual metaphors and gain/loss framing in subsequent studies on persuasive messaging.

The coupled nonlinear Schrödinger equations are invoked to study the behavior of self- and cross-interacting Airy wave packets. We demonstrate that bichromatic pulses possess the main properties of single Airy wave packets—shape invariance and self-acceleration or self-deceleration—when propagating in a dispersive medium. Accounting for nonlinearity leads to a strong dependence of the structure, stability, and propagation velocity of wave pulses on their amplitude. We show that interacting pulses of Airy-type waves can form giant accelerating and decelerating waves.
Drag scaling law and parachute terminal velocity of the dandelion
Authors: Sun Bo-Hua , Guo Xiao-Lin
Published: August 2023

The common dandelion uses a bundle of drag-enhancing bristles (the pappus) that enables seed dispersal over formidable distances; however, the scaling laws of aerodynamic drag underpinning pappus-mediated flight remain unresolved. In this paper, we find that the aerodynamic drag of dandelion is approximately proportional to the −2/3 power of the dandelion pappus Reynolds number, and the terminal velocity of dandelion seeds is proportional to the 3/4 power of dandelion pappus weight. By the way, the Vogel exponent −2/3 for dandelion is determined.

Innate behavior, such as courtship behavior, is controlled by a genetically defined set of neurons. To date, it remains challenging to visualize and artificially control the neural population that is active during innate behavior in a whole-brain scale. Immediate early genes (IEGs), whose expression is induced by neural activity, can serve as powerful tools to map neural activity in the animal brain. We screened for IEGs in vinegar fly
Drosophila melanogaster
and identified
stripe/egr-1
as a potent neural activity marker. Focusing on male courtship as a model of innate behavior, we demonstrate that
stripe

GAL4-
mediated reporter expression can label
fruitless
(

)-expressing neurons involved in courtship in an activity (experience)-dependent manner. Optogenetic reactivation of the labeled neurons elicited sexual behavior in males, whereas silencing of the labeled neurons suppressed courtship and copulation. Further, by combining
stripe-GAL4-
mediated reporter expression and detection of endogenous Stripe expression, we established methods that can label neurons activated under different contexts in separate time windows in the same animal. The cell assembly analysis of
fru
neural population in males revealed that distinct groups of neurons are activated during interactions with a female or another male. These methods will contribute to building a deeper understanding of neural circuit mechanisms underlying innate insect behavior.

Evaluation of the rapid Quidel Sofia Lyme fluorescent immunoassay as a first-tier test in a modified 2-tier testing algorithm for Lyme disease: A comparison with the Zeus ELISA Borrelia VlsE1/pepC10 lgG/IgM assay followed by the Zeus monovalent IgM/IgG confirmatory assay

Published: August 2023

Objectives

Recently modified 2-tier testing (MTTT) algorithms using 2 enzyme immunoassays (EIAs) as opposed to an EIA followed by immunoblot have been approved by the US Food and Drug Administration (FDA) for the screening and confirmation of Lyme disease. The Quidel Sofia Lyme fluorescent immunoassay is a rapid lateral-flow method that can be performed in real time, permitting on-demand testing. We evaluated the performance of the Sofia assay as a first-tier test in an MTTT algorithm.

Methods

We compared the Sofia Lyme test with the Zeus ELISA Borrelia VlsE1/pepC10 lgG/IgM test, followed by the Zeus monovalent IgM/IgG EIA as the confirmatory test.

Results

When used as a first-tier test compared with a standard Zeus MTTT assay, the positive percentage agreement was 91.4%% (95% CI, 77.6%-97.0%). The negative percentage agreement was 100% (95% CI, 94.0%-100%). The overall agreement was 98.3% (95% CI, 94.2%-99.4%). κ = 0.945, indicating “almost perfect agreement.”

Conclusions

The Sofia Lyme test performs well compared with an FDA-approved MTTT.
How Cultural Cognition Informs Differential Treatment in WTO Law and the Climate Regime
Authors: Condon Bradly J
Published: August 2023

Climate change is a core issue for sustainable development and exacerbates inequality. However, in both the WTO and the climate regime, disagreements over differential treatment have hampered efforts to address international inequalities in a way that facilitates effective responses to global issues. Sustainable globalization requires bridging the disparities between developed and developing countries in their capacities to address such matters of global concern. However, differential treatment now functions as a distraction from the global issues it was supposed to address. Cognitive biases distort perceptions regarding the climate crisis and the value of multilateralism. To what extent can cognitive science inform decision making by States? How do we change paradigms (cognitive background assumptions), which limit the options that decision-making elites in developed and developing countries perceive as useful and worth considering? To what extent do cognitive biases and cultural cognition create a barrier to multilateral cooperation on issues of global concern?
CiliaMiner: an integrated database for ciliopathy genes and ciliopathies
Authors: Turan Merve Gül , Orhan Mehmet Emin , Cevik Sebiha , Kaplan Oktay I
Published: August 2023

Cilia are found in eukaryotic species ranging from single-celled organisms, such as Chlamydomonas reinhardtii, to humans, but not in plants. The ability to respond to repellents and/or attractants, regulate cell proliferation and differentiation and provide cellular mobility are just a few examples of how crucial cilia are to cells and organisms. Over 30 distinct rare disorders generally known as ciliopathy are caused by abnormalities or functional impairments in cilia and cilia-related compartments. Because of the complexity of ciliopathies and the rising number of ciliopathies and ciliopathy genes, a ciliopathy-oriented and up-to-date database is required. Here, we present CiliaMiner, a manually curated ciliopathy database that includes ciliopathy lists collected from articles and databases. Analysis reveals that there are 55 distinct disorders likely related to ciliopathy, with over 4000 clinical manifestations. Based on comparative symptom analysis and subcellular localization data, diseases are classified as primary, secondary or atypical ciliopathies. CiliaMiner provides easy access to all of these diseases and disease genes, as well as clinical features and gene-specific clinical features, as well as subcellular localization of each protein. Additionally, the orthologs of disease genes are also provided for mice, zebrafish, Xenopus, Drosophila, Caenorhabditis elegans and Chlamydomonas reinhardtii. CiliaMiner (https://kaplanlab.shinyapps.io/ciliaminer) aims to serve the cilia community with its comprehensive content and highly enriched interactive heatmaps, and will be continually updated.

Financial toxicity among cancer patients, survivors and their families in the United Kingdom: a scoping review
Authors: Ngan Tran T , Tien Tran H , Donnelly Michael , O’Neill Ciaran
Published: August 2023

Background

The aim of this scoping review was to identify key research gaps and priorities in order to advance policy and practice for people living with cancer in the UK.

Methods

The review adhered to PRISMA guidelines for scoping review. We searched MEDLINE, EMBASE, Scopus, Web of Science and Google Scholar on 16 July 2022. There were no restrictions in terms of study design and publication time; gray literature was included. The key words, ‘financial’ or ‘economic’, were combined with each of the following words ‘hardship/stress/burden/distress/strain/toxicity/catastrophe/consequence/impact.’

Results

29/629 studies/reports published during 1982–2022 were eligible to be included in the review. No study conducted a comprehensive inquiry and reported all aspects of financial toxicity (FT) or used a validated measure of FT. The most three commonly reported outcomes related to financial hardship were financial well-being (24/29), benefit/welfare (17/29) and mental health status (16/29).

Conclusions

It is evident that FT is experienced by UK cancer patients/survivors and that the issue is under-researched. There is an urgent need for further research including rigorous studies which contribute to a comprehensive understanding about the nature and extent of FT, disparities in experience, the impacts of FT on outcomes and potential solutions to alleviate FT and related problems.
