Bioinspired Artificial Hair Sensors for Flight-by-Feel of Unmanned Aerial Vehicles: A Review
Authors: Hollenbeck Alex C. , Grandhi Ramana , Hansen John H. , Pankonien Alexander M.
Published: October 2023

Flight-by-feel is an emerging approach to flight control that uses distributed arrays of pressure, strain, and flow sensors to guide aircraft. Among these, hair-type flow sensors have received the least attention yet hold some advantages over conventional sensors. This paper reviews hair-like flow microsensors developed since 2013, focusing on developments in design, construction, and application. Hair-like flow sensors can be found in artificial cochleae, submersible navigation, terrestrial robots, and, rarely but increasingly, on aircraft. In this survey, we categorize hair-like flow sensors into three types (long whisker-like hairs, ultrasensitive microscale hairs, and short trichoid-like hairs), and primarily cover sensors that may be suitable for use on aircraft. The recent progress in flow-based flight control using distributed sensing is also discussed, along with the optimization of sensor placement and the potential for flight-by-feel in sixth-generation military and civilian aircraft designs. This survey aims to provide a consolidated account of the history and state-of-the-art of artificial hair-cell flow sensors, motivate consideration of flight-by-feel as a viable flight control paradigm, and define avenues for future research. As engineering and biological science continue to converge, we hope that researchers in both fields find this survey an inspirational and useful resource.

Qualification of the Legal Relationships Arising in Connection with the Realization of the Right to Education
Authors: Alekseeva A. V.
Published: October 2023

The article is devoted to the analysis of legal relations arising during the realization of the right to education, taking into account the variety of forms of interaction and the peculiarities of the legal status of their participants. Based on the results of the analysis of these legal relations, the author concludes that the predominance of private interests of the student in legal relations, which indicates that educational relations belong to the branch of civil law that requires regulation through civil law mechanisms. The author notes that part of the legal relations directly related to training has a civil nature and is implemented in the form of a contractual obligation to provide educational services (both for cases of paid training on the basis of a signed contract, and for cases of training at the expense of budget financing). Based on the conclusions about the legal nature of the relations under consideration, proposals are put forward to amend Chapter 39 of the Civil Code of the Russian Federation, allowing the rules of this chapter to apply to educational relations based on budget financing. The proposed changes are aimed at ensuring equal learning conditions and ways to protect the civil rights of students, regardless of the source of funding for training.

Its presentation is the mixture of iris and corneal anomalies which may lead to low vision or blindness due to secondary glaucoma or corneal decompensation. We report a case of ICE syndrome in one eye and primary angle closure suspect in the other eye, both eyes having controlled intraocular pressure but low vision due to pars planitis/intermediate uveitis with macular oedema and also evaluating more potential inflammatory causes.
The Library as a Driver of Open Science: Essential Competences of the Librarian
Authors: Rykhtorova Anna E.
Published: October 2023

There is a need to define the role of the library in the development and implementation of open science, based not only on the widespread concept of open access to scientific publications, but also on other principles. UNESCO’s concept of open science is presented in relationship with the concept of open knowledge analyzed in the context of three approaches: 1) “openness” from the point of view of copyright (unrestricted reading, distribution, processing of the original work and publication of derivative works); 2) scientific communication (interpretation of knowledge and its transfer between different scientific disciplines, governmental structures, social actors, non-scientists and non-scientific institutions, as well as publicly accessible communication); 3) open, comprehensible, verifiable knowledge, accessible to all members of society by means of well-known criteria. The directions of libraries' activities within the framework of open science are proposed. Some of the competences necessary for such activities are fixed in the professional standard “Specialist in Library and Information Activities”: the ability to organise a multifunctional library space, analytical and synthetic processing of documents, etc. The competences of the library specialist are also required. In addition, the library specialist needs additional knowledge about the essence of open knowledge (open scientific knowledge) and its key components, the basics of intellectual property legislation, the basics of research ethics, the organisation of open reviewing, the use of altmetrics, the organisation of open learning platforms. Taking into account the amount of knowledge and skills required, as well as the specificity of their application areas, it seems reasonable to train first of all employees of scientific, scientific-technical, and university libraries.

With the new competences, library professionals will be able to contribute to the effective integration of their institutions into the research process. The library can become a real driving force for open science.
Shaping the Country’s Cultural Sovereignty: Murmansk Hosted the All-Russian Library Congress
Authors: Trushina Irina A.
Published: October 2023

June 10—17 in Murmansk, the Library Capital of Russia 2023, the All-Russian Library Congress: XXVII Annual Conference of the Russian Library Association (RLA) took place. The event was supported by the Government of the Murmansk Region. The Congress was attended by 957 delegates from 68 regions of Russia.

The professional programme included two plenary sessions and 57 sectional and special events with 634 presentations. The Congress was held under the sign of two significant dates — the 85th anniversary of the Murmansk Region and the 85th anniversary of the Murmansk State Regional Universal Scientific Library. The grand opening and the first plenary session took place on June 12 2023 on the Day of Russia. On June 13 and 14 2023 the work continued at the breakout sessions. The results of the congress were summed up at the final plenary session on June 15 2023.

The relevance of the main theme of the Congress “Library — the cultural code of Russia” is connected with the state cultural policy and the tasks set for libraries. The definition of the cultural code of Russia is conditioned by the need to consolidate the citizens of the country on the basis of a common system of values, the formation of cultural sovereignty. The issues of implementation of one of the core documents of the library industry — “Strategy for the librarianship development in the Russian Federation for the period up to 2030” were raised. The work of libraries in new social and geopolitical conditions was analyzed. The “Model Regulations on the Organisation of Research Activities of the Central Library of the Subject of the Russian Federation” was adopted.

Investigation of Dynamical flexibility of D5SIC-DNAM inside DNA duplex in Aqueous Solution: A Systematic Classical MD Approach
Authors: Debnath Tanay , Cisneros G. Andres
Published: October 2023

Incorporation of artificial 3rd base pairs (Unnatural base pairs, UBPs) has emerged as a fundamental technique in pursuit of expanding the genetic alphabet. 2,6-dimethyl-2H-isoquiniline-1-thione: D5SIC (DS) and 2-methoxy-3-methylnaphthalene: DNAM (DN), a potential unnatural base pair (UBP) developed by Romesberg and colleagues, has been shown to have remarkable capability for replication within DNA. Crystal structures of a Taq polymerase/double-stranded DNA (ds-DNA) complex containing a DS-DN pair in the 3’ terminus showed a parallelly stacked geometry for the pre-insertion, and an intercalated geometry for the post-insertion structure. Unconventional orientations of DS-DN inside a DNA duplex have inspired scientists to investigate the conformational orientations and structural properties of UBP-incorporated DNA. In recent years, computational simulations have been used to investigate the geometry of DS-DN within the DNA duplex; nevertheless, unresolved questions persist owing to inconclusive findings. In this work, we investigate the structural and dynamical properties of DS and DN inside a ds-DNA strand in aqueous solution considering both short and long DNA templates using polarizable, and non-polarizable classical MD simulations. Flexible conformational change of UBP with major populations of Watson-Crick-Franklin (WCF) and three distinct non-Watson-Crick-Franklin (nWCFP1, nWCFP2, nWCFO) conformations through intra and inter-strand flipping have been observed. Our results suggest that a dynamical conformational change leads to the production of random distribution of several intermediates. Simulations with a short ds-DNA duplex suggest nWCF (P1 and O) as the predominant structures, whereas long ds-DNA duplex simulations indicate almost equal populations of WCF, nWCFP1, nWCFO. DS-DN in the terminal position is found to be more flexible with occasional mispairing and fraying. Overall, these results suggest flexibility and random conformational distribution of the UBP as well as indicate varied conformational distribution with the increase of the length of the DNA strand.
Controlled and Regioselective Ring-Opening Polymerization for Poly(disulfide)s by Anion-Binding Catalysis
Authors: Du Tianyi , Shen Boming , Dai Jieyu , Zhang Miaomiao , Chen Xingjian , Yu Peiyuan , Liu Yun
Published: October 2023

Poly(disulfide)s are an emerging class of sulfur-containing polymers with applications in medicine, energy, and functional materials. However, the constituent dynamic covalent S−S bond is highly reactive in the presence of sulfide (RS−) anion, imposing a persistent challenge to control the polymerization. Here, we report an anion-binding approach to arrest the high reactivity of RS− chain end to control the synthesis of linear poly(disulfide)s, realizing a rapid, living ring-opening polymerization of 1,2-dithiolanes with narrow dispersity and high regioregularity (Mw /Mn ~ 1.1, Ps ~ 0.85). Mechanistic studies support the formation of a thiourea-base-sulfide ternary complex as the catalytically active species during the chain propagation. Theoretical analyses reveal a synergistic catalytic model where the catalyst preorganizes the protonated base and anionic chain end to establish spatial confinement over the bound monomer, effecting the observed regioselectivity. The catalytic system is amenable to monomers with various functional groups, and semicrystalline polymers are also obtained from lipoic acid derivatives by enhancing the regioregularity.
Modulating Molecular Aggregation of Luminogens: Bridging the Gap Between Solutions and Solids
Authors: Meng Peng , Lau Andreis , Miyajima Daigo , Alam Parvej , Qiu Zijie , Tang Benzhong
Published: October 2023

In the past two decades, the advancement of aggregation-induced emission (AIE) has greatly advanced our understanding of organic luminescence and facilitated the application of organic luminescent materials. AIEgens emit weakly in solutions but strongly in aggregated states. This significant difference in luminescence between solutions and aggregated states of AIEgens has shown that there is much to explore in the mesoscopic world (the intermediary phase). Accordingly, the research paradigm is shifting towards aggregate science. The path to new aggregate materials relies not only on molecule syntheses but also on the control of molecular aggregation. Molecular aggregation bridges the gap between solutions and solids, which is of great significance for developing aggregate science. In this perspective, we outline three general strategies for managing molecular aggregation to stimulate new ideas and provide guidance on controllable molecular aggregation.
Aryl Sulfonium Salt Electron Donor-Acceptor Complexes for Halogen Atom Transfer: Isocyanides as tuneable coupling partners
Authors: Zhao Huaibo , Dafnae Cuomo Valentina , Rossi Ashton James , Procter David
Published: October 2023

The photoactivation of sulfonium salt EDA complexes provides a mild platform for aryl radical-mediated halogen atom transfer activation of a wide range of functionalized alkyl iodides. Using an aryl sulfonium salt with carbonate as an inexpensive donor for EDA complex formation, the general reaction platform has been applied in a divergent, metal-free pho- tochemical approach to nitriles and amides. This divergency was made possible by tuning the isocyanide radical traps. For example, the identification of a readily accessible, bench-stable and crystalline amide containing isocyanide, grants access to nitrile products with complete selectivity.

Published: October 2023

The burgeoning interest in new electrochemical methods holds promise to provide a plethora of strategic disconnections for pharmaceutical compounds, which are safer, less wasteful, and more streamlined than traditional chemical strategies. The use of organic electrochemistry in the commercial production of pharmaceuticals is exceedingly rare due to the lack of a modular infrastructure. Herein, we describe the use of cascading continuous-stirred tank reactors (CSTRs) with individual cell potential control applied over reaction ‘stages’ which demonstrate a balance between high selectivity and throughput necessary for electrochemistry to be a viable strategy in the pharmaceutical space. Using the high degree of control of cell potential afforded by this reactor design, a 1 kg demonstration was achieved in 9 hours with high selectivity and yield (2.6 kg/day throughput).
Generalizing asymmetric and pseudo-Voigt functions by means of q-Gaussian Tsallis functions to analyze the wings of Raman spectral bands
Authors: Sparavigna Amelia Carolina
Published: October 2023

It is important, for further applying the q-Gaussian Tsallis functions, to discuss how they can generalize asymmetric and pseudo-Voigtian functions. Some remarks about Voigt functions are also stressed, regarding the behavior of the wings of Raman spectral components. The use of Voigt and pseudo-Voigt functions implies the wings as Lorentzian, but this is not observed for the Raman bands. At the same time, the wings are not Gaussians, and for this reason q-Gaussians are fundamental for evidencing the wing behavior.

An Investigation on Eye Tracking Indicators to Detect Alertness on Inspection Jobs with Sleep Limits and Gender Differences
Authors: Siswanto Daniel
Published: October 2023

Eye tracking (ET) has been widely used to detect ocular changes that are also correlated with fatigue. However, whether there is an ET indicator capable of detecting fatigue closely related to vigilance decrement is unknown. This study aims to determine which ET indicators are sensitive in detecting changes in vigilance due to sleep restriction (4 and 8 hours) in different gender. Fifty-six participants (28 men, 21.32 ± 1.16 years and 28 women, 21.5 ± 1.2 years) were involved in this study. Using an eye tracker device, participants were asked to simulate inspecting defects (dirt, scratches, missing parts, and poor assembly) at 50 flashlights. In addition, vigilance assessment was carried out with the Psychomotor Vigilance Task (PVT) and the Karolinska Sleepiness Scale (KSS). The results of ANOVA showed that sleep restriction affected the mean RT (p-value = 0.001), minor lapse (p-value = 0.036), mean 1/RT (p-value = 0.001), saccadic velocity (p-value = 0.001), and KSS (p-value = <0.001). Gender influenced the mean 1/RT (p-value = 0.016), pupil diameter (p-value = 0.022), and saccadic velocity (p-value = 0.030). The Pearson correlation test shows a weak relationship between the ET and PVT indicators. However, saccadic velocity has the potential to be able to detect changes in vigilance because it is influenced by sleep restriction. Further research is still needed to confirm these results because the correlation between saccade velocity and PVT indicators in this study still needs to show a stronger relationship to become a vigilance indicator.
Risk Assessment for Reimbursement of Microfinance Institutions
Authors: Miled Kamel Bel Hadj , Landolsi Monia
Published: October 2023

Purpose: Understanding the repayment behavior of the borrower is very important to the lending decisions of financial institutions and thus helps to promote the development of microfinance. This paper examines the factors that affect the repayment default of microfinance in Tunisia.
 
Theoretical framework: Some studies highlight the importance of incorporating macroeconomic conditions for the estimation of borrowers’ credit risk (Bellotti & Crook, 2013). However, IADB (2020) announced that after the start of the Covid-19 pandemic in the region, microfinance institutions had restricted liquidity, which affected the availability of credit.  Therefore, for the purpose of the present article, the literature on default in MFIs analyzes the credit risk and factors that influence granted loans
 
Design/Methodology/Approach:  We carried out a survey, with a non-stratified sample of 320 microcredit beneficiaries, during 2021 in Enda-inter-Arab agencies located in the region of Sousse- Tunisia. We introduce a binary logistic regression model  to predict the values taken by a discrete variable from a series of continuous or binary explanatory variables.
 
Findings: We show that borrowers’ socioeconomic characteristics, total loan, repayment period and past participation in microcredit loans have significant impacts, as special features, on their default rates.
 
Research, Practical & Social implications: This paper has been designed to provide some valuable contributions in improving the repayment performance and can be significant political involvement, derived from the strong relationship between the level of poverty and the success of loan repayments. Indeed, the level of borrowers’ poverty must be given considerable weight before the loan is disbursed.
 
Originality/Value: The results indicate that the qualification and age of the workforce should be considered a basic requirement before the granting of loan. In addition the microfinance institution's credit policy should also consider service projects a priority.

Sharing the wealth: pollen partitioning in a Cucurbita crop pollination system with reference to the wild hoary squash bee.
Authors: Chan Sue , Raine Nigel E.
Published: October 2023

Cucurbita pepo crops (pumpkin, squash) are entirely dependent upon insect pollinators for reproduction. In Ontario, Canada, their most important pollinator is the hoary squash bee (Eucera pruinosa), a wild ground-nesting, solitary bee whose only source of pollen in the region is Cucurbita crops. As such, in this context, we have a unique opportunity to study pollen partitioning in a cropping system in which a wild bee is the main pollinator. To evaluate pollen partitioning in the system, we measured pollen production by the crop, the pollen lost as waste due to the activities of bees in staminate flowers, pollen loads collected by female squash bees, and the number of pollen grains in fully provisioned hoary squash bee nest cells, and we compared these to the crop’s pollination requirements as reported in the literature. From the perspective of both plant and bee reproduction, about 13% of the pollen produced by staminate acorn squash flowers was wasted, but it may be harvested by other organisms like ants. After waste is accounted for, about 9% of the pollen left is needed for plant reproduction leaving the remaining 91% available for hoary squash bee reproduction. We also evaluated the mass of pollen a female hoary squash bee could carry in a single foraging trip relative to her own body mass (~4%). The information contained here is useful for understanding the relationship between a crop and an oligolectic wild bee species or to set up controlled, field realistic experiments involving the hoary squash bee.
On the compliance of the productivity of domestic combine harvesters and the yield of grain and leguminous crops in Russia
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Mikhaltsov Evgeniy M.
Published: October 2023

The industry of growing grain and leguminous crops is not supported by the production of domestic combine harvesters capable of ensuring the organisation of harvesting operations with a high level of efficiency in the whole range of yields typical for Russian conditions. The analysis of the main characteristics of modern “Rostselmash” combine harvesters in relation to the yield of grain and leguminous crops has revealed the need to improve the range of combine harvesters produced in the Russian Federation. The calculation and graphic method has shown that in the line of domestic combine harvesters there are no models designed for harvesting grain and leguminous crops with yields up to 1.7 tons/ha and from 2.9 to 3.5 tons/ha. The absence of these models leads to higher production costs of cereals in farms, for which this yield is typical. It has been established that harvesting grain and leguminous crops of different yields requires a range of 5 models of combine harvesters. Each of them will have 100% use and maximum efficiency of utilization in the yield range, for which it is designed. The range of models, built according to the proposed principle, will provide the need of any farm in combines for harvesting grain and leguminous crops with yields from 0.87 to 10 tons per hectare. The graphical analysis method facilitates the selection of a rational combine harvester model suitable for local conditions by the criterion of maximum loading of the threshing and separating device.

Hydrodynamic lubrication increases the service life of connections. The quality and durability of connections with hydrodynamic lubrication is determined by functional parameters, including the characteristics of strength, rigidity, wear resistance and accuracy characteristics. In these joints, the accuracy characteristics are gaps, surface roughness of parts, shape deviation and surface arrangement. To ensure the largest supply of materials and parts and the greatest resource, the authors calculated a fit and selected for connecting the plain bearing of the gearbox of the grain drying screw conveyor operating under hydrodynamic friction. For this connection, two fits were chosen by calculation: Ø50H9/g9 and Ø50H7/g6. Based on the rational assignment of the surface roughness of rubbing pairs, it is necessary to assign a fit Ø50H7/g6, which has an accuracy factor of 22. For a fit Ø50H9/g9, the accuracy factor corresponds to 7. The recommended fit Ø50H7/g6 is provided by honing the hole and fine grinding the shaft. It is the fit that provides the largest stock of parts materials for wear and the largest connection resource.

Ensuring the safety of grain raw materials during storage is an urgent problem. The most efficient and environmentally friendly method is the microwave radiation method. To obtain products that meet the requirements of quality and safety, it is necessary to determine the effective modes of exposure. For this purpose, the decontamination of corn and rice grain depending on the heating rate and time of microwave radiation exposure on the grain was studied on the MkP‑1200 unit with the 2450 MHz mode of action. Microbiological indices of grain determined according to standard methodology showed species diversity of microorganisms on untreated grain. Maximum disinfection of rice grain was observed at a heating rate of 0.63 to 0.71°C/s, treatment time of 122 to 171 s. Maximum disinfection of corn grain was observed at a heating rate of 0.6 to 0.69°C/s. The electromagnetic field of ultra-high frequency minimises indicators of microbiological contamination and provides the best indicators of safety and quality of grain during storage.

Intrauterine insemination (IUI), it is a type of artificial insemination, used to treat infertility by which the Sperm that have been prepared and placed directly into the woman’s uterus around the time of ovulation. The main purpose of this procedure is to enable the sperm to swim into the fallopian tubes and fertilize a ready egg in order to lead to a natural pregnancy. IUI can be coordinated with the normal cycle with fertility or medications depending on the reasons for infertility The IUI outcome still low about 20-25% so adding number of biochemical factors to the culture medium which are essential to regulate the fertility potential of spermatozoa, for example, platelet-activating factor (PAF) which is a unique and novel signaling phospholipid that has multiple biologic properties have been tried. To determine the effect of adding the PAF into the culture medium to prepare and activate the semen samples of non-male factor infertility (normal semen analyses). This study was carried out in the Infertility Unit, AL-Hussein Teaching Hospital, Al-Nassirya City, through the period from 30th of October 2020 till 17th of April 2021. The study included thirty couples who are complaining from infertility (they failed to conceive after one year at least of regular unprotected intercourse. The frequency distribution of enrolled infertile men with normozoospermia Baseline characteristics of seminal fluid analysis of males with normozoospermia those with PAF are Semen volume ml, pH, Sperm concentration before million/ml, Sperm motility %, morphologically normal sperm % , were Mean ±SD (3.10 ±1.23, 7.39 ±0.03, 46.67 ±15.31, 1.33 ±3.52, 36.00 ±5.07) respectively. Certain sperm parameters were highly improved after in vitro activation by PAF medium of normozoospermic samples.

The most popular technique of making ready sperm is the swim-up procedure, in which sperm is selected on motility and ability to swim out the plasma of the semen due to the plasma contains decapacitation factors that alter sperm's ability to fertilize. This research covers 119 semen samples from men visiting the fertility clinic of the High Institute for Infertility Diagnosis and ART that included normal and abnormal sperms parameters as stated in the WHO. The semen sample was dissected into 2 portions: First grouping was affected by the equal quantity of phosphate buffer saline (250) μm contain 10% human serum albumin (HSA) while the second grouping was affected by the equal quantity of phosphate buffer saline (250) μm contain 10% human serum albumin (HSA) with added 2% platelet-rich plasma. Then samples are prepared by the swim-up method for evaluation parameters of the sperm. Swim-up PBS+PRP(HAS) media resulted in the highest sperm concentration, highest total count, highest total motility, highest progressive motility A+B, A, and B, the highest concentration of active motile sperm % and highest normal morphology sperm % after that swim up –PBS (HAS), sequentially in a highly significant manner (p < 0.001). We conclude the insertion of PRP resulted in results that are technically far two methods with regarding sperm concentration, total count, total motility, progressive motility A+B, A, and B, non-progressive motility (C), immotile sperm (D), the concentration of active motile sperm % and normal morphology sperm and the values were far better in Swim-up PBS (HAS) with added 2% PRP than those produced by swim-up –PBS (HAS) alone.

Human peptidoglycan recognition protein-1 (PGLYRP‐1) protein molecule activation in the semen of infertile patients has been suggested to induce a negative impact on seminal fluid analysis. 176 infertile patients included in this study were tested for seminal fluid analysis, Endtz test, and PGLYRP‐1 in seminal plasma using enzyme-linked immunosorbent assay (ELISA) technology. PGLYRP‐1 is evident in the seminal plasma of infertile men and is statistically different according to the type of infertility. The concentration of PGLYRP-1 in the semen is directly proportional to the presence of leukocytes (Endtz test), which is reflected negatively on the quality of the semen. To the best of our knowledge, this study has not been done in Iraq or elsewhere. The presence of PGLYRP-1 protein in the semen may be evidence of leukocytospermia that may be related to bad quality for semen across infertile men with higher sensitivity than the Endtz test.
