Preparation of slow-release carbon source fillers from agricultural solid waste for efficient nitrogen removal from municipal wastewater: Removal performance, microbial community and mechanisms

In this study, five types of agricultural wastes, were used as alternative materials for slow-release carbon source, alternative materials were prepared as slow-release carbon source fillers (ZCF) using a no-sintering method, and studied by leaching elements, carbon release, nitrification and denitrification potential, and bio-attachment performance, walnut shell-based filler was found to have better performance in terms of persistence of carbon release, impact stability, carbon biochemistry and green safety. When HRT was 8 h in H-O, 12 h in H-A, and R was 100 % and C/N was 2 in H-Z BAF, the average concentrations of effluent NH4+-N and TN were only 0.4 and 12.2 mg/L, which achieved the high efficiency and economy of H-Z BAF under low C/N conditions. The newly prepared ZCF had a rougher outer surface, a uniformly distributed flocculent structure and numerous microporous channels on the inner surface, and the carbon source inside the filler was degraded or transformed by microorganisms, as compared to the filler in H-O and H-A at the later stage of use. The abundance of nitrifying bacteria, denitrifying bacteria was increased in the H-Z BAF, and that functional CAZymes were enriched and involved in the degradation of cellulose and hemicellulose, can be efficiently utilized by microorganisms. This study provides technical support for the development of cheap, stable and efficient slow-release carbon sources and their application in denitrification of municipal wastewater plant tailwater.

О литейной форме из поселения эпохи бронзы Тарангул в Актюбинском Приуралье

Introduction. In 2021, the Mugodzhar (Mugalzhar) Crew of the Margulan Institute of Archaeology investigated the site of Tarangul and discovered a casting mold ― a rare artifact of utmost interest related to metal production and processing. Goals. The article seeks to describe and analyze the Bronze Age mold from Tarangul located in the Aktobe Cis-Urals, introduce into scholarly circulation some newly obtained scientific data. Results. The implemented analyses include those of natural science (micro-wear and spectral ones) and comparative typology, the latter to yield a classification of castings and their cultural affiliation. The tool mold has two surfaces with negative impressions. The first one was used to cast three sickles, while the second one (once consisted of two pieces) would cast a flat adze. The shapes attest to the mold was used to cast Kundravinskaya-type sickles widespread across the Late Bronze Age Southern Urals, Middle Volga, and Western Siberia. Kundravinskaya-type sickles are associated with the Alakul culture, the Kozhumberdy cultural group being a local variant of the latter in the region under study. The shape of the impression on the reverse side is characteristic of adzes from the Alakul era discovered in western parts of Eurasia’s steppe zone. The study concludes the mold had first consisted of two pieces and been used to cast adzes, and after the other piece was lost or damaged it started being used to cast sickles. The spectral analysis shows the castings were basically made from copper, and detects some traces of alloying. Another finding is that the three mold negatives were used not simultaneously but rather when and as it was necessary. In general, the conducted tests have well reconstructed the manufacturing techniques and stages of use for the mold from the Late Bronze Age settlement of Tarangul in the Aktobe Cis-Urals, and highlighted certain aspects in the study of molds as a specific source on metal production techniques and technologies in prehistory.

Gender differences in illicit drug access, use and use disorder: Analysis of National Survey on Drug Use and Health data

Although gender differences in the prevalence of substance use disorders (SUD) have been well-characterized, little is known about when gender differences emerge along the continuum of substance use. Understanding the contribution of gender to risk at key transition points across this continuum is needed to identify potential mechanisms underlying gender differences and to inform improved gender-responsive interventions. To characterize gender differences in the progression of cannabis, cocaine, and heroin use, the current study used data from the United States-based 2015–2019 National Survey on Drug Use and Health to quantify gender differences in: (1) perceived access to drugs, (2) lifetime drug use among individuals with at least some access, and (3) past-year SUD among those who had ever used each drug. Logistic regressions were conducted for each drug to examine gender differences across all three stages, controlling for sociodemographic factors and survey year. Compared to women, men had higher odds of reporting access to and lifetime use of all three drug types. Men also had higher odds of past-year cannabis and cocaine use disorders compared to women. Results suggest gender differences emerge in the earliest stage of drug use (access) and may accumulate across the stages of use. The magnitude of gender differences varied across stages, with the largest differences observed for odds of drug initiation among those with perceived access to each drug. Longitudinal data will be needed to confirm these findings and to provide insight into potential contributors to gender-specific risk and intervention targets across the continuum of drug use severity.

Adoption of artificial intelligence in financial services: The case of robo-advisors in India

Robo-advisors are still in their nascent stages of use, and this technology has yet to find wider acceptance with investors. Our study extends the domain of technology acceptance to robo-advisors by identifying the drivers of investor adoption. Investment decisions carry high risks; thus, there is a greater need to understand investor behaviour to adopt robo-advisors. Trust, anxiety, performance expectancy, and preference for human advisors are used as variables to predict investors’ intentions. PLS-SEM is employed to examine the data with a sample size of 445 investors. Results suggest that all these variables play a significant role in determining the behavioural intention of investors towards the adoption of robo-advisors.

Clinical Uses of Nanopore Sequencing in Recurrent Acute and Chronic Otitis Media

Background. Otitis Media (OM) is a widespread problem that has an incidence of 10.85% worldwide, 51% occurring under the age of 5. Emergence of drug resistant bacteria contribute to high incidence of recurrent acute otitis media (AOM) and chronic otitis media with effusion (COME). Despite this, the standard of care for treatment is empiric antibiotics. Molecular microbiology diagnostics may enable clinicians to provided pathogen directed antibiosis. Nanopore sequencing is a highly accurate method of identifying a broad range of pathogens when compared with multiplex PCR. We hypothesize that nanopore sequencing is an effective method for detection of pathogens in the middle ear and nasopharynx of patients with recurrent or chronic OM.
 Methods. Bacterial Culture, multiplex PCR (BioFire PNA panel), and nanopore sequencing (MinIon, Oxford Nanopore Technologies) were tested on 60 middle ear and nasopharynx samples. Chi-Square test was used to examined differences in bacterial identification among the methods.
 Results. Bacterial identification using nanopore proves to be more sensitive in identification of 16 of the 18 unique pathogens when compared with multiplex testing. Of the 5 most common OM bacterial pathogens (S. pneumoniae, M. catarrhalis, H. influenza, S. aureus, P. aeruginosa), nanopore identified 3 pathogens (S. pneumoniae, M. catarrhalis, P. aeruginosa) at higher levels, 1 at the same rate (H. influenza), and 1 did not receive any readings (S. aureus).
 Conclusion. This is the first study to utilize nanopore sequencing to assess pathogens in the middle ear fluid of children with OM. While nanopore genomic sequencing is still in the early stages of use, it has potential to comprehensively identify bacteria with more sensitivity when compared to the current clinical standards. The next step of data analyzation will include bacterial identification in nanopore that multiplex PCR and traditional bacterial cultures cannot test for.

A complete solution for anti-jaming radio data-link of an unmanned aerial vehicle

The effectiveness of an unmanned aerial vehicle's flight mission over a given distance depends on many factors. However, one of the key factors in the successful completion of a flight mission is the availability of high-quality management and control of telemetry by an unmanned aerial vehicle, which in turn is determined by a reliable radio communication between the ground control station and the unmanned aerial vehicle. The current stage of use of unmanned aerial vehicles is characterised by the use of active jammers of various types and purposes, the purpose of which is to disable control channels, navigation channels, telemetry channels and data transmission channels of FPV unmanned aerial vehicles in order to prevent the successful completion of the flight mission of the vehicle. The article considers conceptual issues of implementing a guaranteed interference-free radio data transmission and control of an unmanned aerial vehicle in the conditions of active jamming interference when combining various technological solutions. These solutions include the selection and justification of a special frequency range, the use of structural circuit solutions for interference protection of the radio data transmission and control line; the use of a specific scheme for organising communication with an unmanned aerial vehicle; the use of a transceiver and portable and light antennas for the radio channel that meet reasonable technical requirements; the implementation of the possibility of real-time monitoring of the interference situation on board the unmanned aerial vehicle and detection of the type of interference; ensuring flight in the sector. The requirements were justified and options for selecting a transceiver and antenna were proposed. A structural diagram of the radio line is developed and options for its use as a data transmission and control radio line for an unmanned aerial vehicle are proposed. Examples of real-time tracking of the interference situation on board an unmanned vehicle and detection of the type of interference are given. A flight option in the sector without the use of antenna tracking is calculated and justified. The approximate values of the signal at the receiver input of the unmanned vehicle are calculated.

Sentinel lymph node biopsy in patients with breast cancer. Experience in implementing at the regional level. Priority issues

Background. Despite the fact that sentinel lymph node biopsy (SLNB) in breast cancer patients has become a routine diagnostic procedure, it is still of great interest to researchers, since the priority issues of choosing methodology, equipment, technology, and stages of use are still being discussed. Although all obstacles to this technique implementation into routine clinical practice have been eliminated, SLNB in locally advanced breast cancer is still rarely used. We describe the experience of implementing SLNB in Nizhny Novgorod Regional Clinical Oncology Dispensary. We also discuss organizational, tactical, and practical approaches aimed to minimize the number of errors in technical terms, as well as to choose a multidisciplinary approach to the development of regulations for the examination and treatment of patients with locally advanced breast cancer.Aim. To assess the efficacy of SLNB implementation for patients with locally advanced breast cancer at the regional level.Materials and methods. This study included 500 patients with invasive (T1–2) breast cancer with clinically negative sentinel lymph nodes of all immunohistochemical subtypes that had undergone SLNB and histological examination. Sentinel lymph nodes were visualized using the radioisotope colloid 99mTc-Nanotop. We present the implementation algorithm for this procedure into routine clinical practice and evaluate short-term results.Results. A total of 500 patients have undergone SLNB. The first 30 cases were considered pilot cases, where all patients positive for sentinel lymph nodes additionally underwent standard axillary lymph node dissection. We observed a 100 % concordance of histological results. Then the surgery was routinely performed for all patients from this category. The assessment of short-term surgical outcomes demonstrated significant improvement of the postoperative period, reduced frequency of postoperative complications (persistent seroma of the axillary area to 2.85 %), reduced length of hospital stay (by 52.7 %) and improved functional and aesthetic results in the majority (>62 %) of patients.Conclusion. Our algorithm of SLNB use in patients with breast cancer in routine clinical practice at the regional level allows for rapid method implementation, reduced length of hospital stay, better functional and aesthetic results, and lower incidence of persistent seroma of the axillary area.

Experts’ Evaluations and Opinions Concerning Deployment of Connected and Autonomous Vehicles

Connected and autonomous vehicles (CAVs) afford the possibility of improving the transportation system by reducing traffic congestion and accidents. They also can increase employment and shopping opportunities for persons who cannot drive. During the early stages of use, CAVs will have to share the roadways with human-driven vehicles (HDVs), necessitating effective communication among CAVs and HDVs about their intentions and future actions. We previously reported results of a survey of drivers that assessed their knowledge of CAVs and thoughts about their deployment. In the present study, we describe the evaluations and opinions of CAV experts from academia, industry, and government obtained from in-depth interviews.

Repository for academic documents, algorithms and data: A utility in an educational context

Data repositories currently constitute essential programs within institutions. In fact, universities are the primary institutions that promote the creation, management and storage for the safekeeping of a variety of documents, data and/or projects. This work is carried out within the framework of institutional need and the application of knowledge by the students and professors in the software degree program at a university in Ecuador. This project centers on a web application that makes it possible to manage, upload and download resources. This initial version focuses on the resources related to academic projects, data sets and algorithms. The scalability characteristics have been carefully introduced to ensure a progressive evolution of other types of resources and functionalities, in accordance with educational needs. Several aspects of the web interfaces are based on the characteristics of other existing repositories, and a series of tests related to functionality have been conducted in order to move beyond the introductory stage of use, to begin with, by the university community. This project is carried out according to a conception based on contributions, in which the agents, in principle, are members of the institution. The intensive and collaborative use of this utility will contribute to the growth of a data culture within the institution. Furthermore, the collection and organization of data for the purposes of study and research by the different university degree programs makes it possible to analyze and contrast them from different perspectives.

The experimental modeling of asbestos-tempered vessels

The tradition of mixing asbestos into pottery clay originated near the deposits of this mineral on the lake Saimaa (Finland) in the 5th millennium BC. By the second half of the 4th millennium BC its area reached the Arkhangelsk and Vologda Regions of Russia in the east. The aim of the work is to review the functional hypothesis, according to which the widespread use of asbestos as an admixture is due to its advantages over other additives facilitating the process of molding and drying, preventing flaws during firing, making the vessel durable and easy to use. According to the results of our experiments on the making of vessels and model samples with asbestos it turned out that the used asbestos of the Chevzhavara deposit (tremolite-ferroactinolite) does not have such advantages. The most important problem was the dissociation of asbestos at temperatures above +700C. After such firing, the vessels were destroyed, and the asbestos itself became brittle. It can be assumed that in order to minimize losses during the firing, the ancient potters could beforehand hold the asbestos at a high temperature so that it would lose the main amount of water but keep its stability. It can be preliminarily concluded that asbestos admixture at an early stage of use did not have clear advantages over other additives. The reasons for the initial interest in asbestos as an additive could be other, e.g. socio-cultural. A special developed technology for processing asbestos, which made it possible to use its advantages, spread around the beginning of the Bronze Age and may be associated with the beginning of metalworking.

The influence of grazing and indoor systems on goat milk, brined cheese and whey quality

This study aimed to investigate whether diet and different goat production systems affect the quality of milk, white-brined cheese and whey. It also aimed to determine the suitability of goat's milk for the production of white-brined cheese. The physicochemical composition and hygienic quality of raw goat's milk were studied, as well as the fatty acid profile and nutritional indices of milk and white-brined cheese. Traditional white-brined cheeses were produced from bulk goat milk from two farms in three samples. The results confirmed that different husbandry systems and diets influence the physicochemical composition of goat milk and cheese and their fatty acid profile. Milk and cheese from grazing goats contained significantly more (p<0.05) fat, protein, total solids and a higher percentage of cheese yield. Nutritional indices were also more favourable, with a lower atherogenic (AI) and thrombogenic (TI) index and a higher health-promoting index (HHP) and hypocholesterolemic/hypercholesterolemic ratio (HH). Goat grazing contributed to a higher content of n-3 fatty acids in milk and cheese and thus to a lower n-6/n-3 ratio. Cheese-making efficiency and protein recovery in the curd (%REC) was better with pasture milk, whereas fat recovery was better with milk from housed goats. Consumers rated the unripened white cheeses from both production systems the highest. In addition, the production of white cheese with brine results in good quality whey with significant health benefits. Natural pasture provides significantly more benefits to goats than confinement, especially in the early stages of use. This contributes to the high nutritional value of goat's milk, cheese and whey.

THE «HOUSEHOLD OF CERAMIST 2» COMPLEX ON THE TRIPOLIAN GIANT-SETTLEMENT TALIANKI

The Tripolian archaeological expedition of the Institute of Archaeology of the National Academy of Sciences of Ukraine during 2018—2019, 2021—2022 explored a separate planographic unit of the settlement-giant Talianki which was named «Household of ceramist 2». The complex consists of five ground dwellings, one pottery kiln (G) and a place from a possible kiln, two large objects («pit-paddocks») and other objects of various purposes (small depressions, workplaces).
 Dwellings 54—56 consisted of two parts — a smaller entrance and a large residential one. The interior of the residential part is standard; the entrance framed with decor. Building 53 is characterized by its larger dimensions with an additional third room. The southernmost building 57 was much smaller, interior details almost not survived. At the lower floor of the building floor greases or pavements (buildings 53, 57), and depressions are found.
 The kiln «G» was located outside the residential area of the settlement near the northwestern part of pit 3. The kiln shape is close to rectangular with rounded corners. Kiln is two-chamber with vertically connected joints. The combustion chamber is separated from the burning compartment by a grid and coupled to warm air vents. This kiln is built of stones, clay and a significant number of pottery fragments. The geomagnetic anomaly corresponding to the characteristics of the kiln was located near the western side of pit 4. No visible remains of the kiln found at this location.
 Large pits 3, 4 were located on the line of deepened
 objects, which runs parallel to the line of ground buildings already outside the residential zone of the settlement. Each of the pits consisted of two depressions. Several stages of use recorded: selection of local clay for construction («toloka» / pit-paddock), use as dugout, repeated disposal of waste (debris of furnace vaults, defective products, ash and utility waste).
 A large number of ceramic fragments, bone and stone tools, anthropomorphic and zoomorphic figurines, fragments of models of houses, sledges, etc. are found inside and around the sites. The mass finding of ceramic items in pit 4 deserves special attention. These are 494 whole and fragmented clay items. In addition to the impressive amount of these items in one object, special attention is drawn to unfinished or damaged figurines, as well as prepared individual parts of future products and flattened lumps of clay. Given the large amount of this kind of «production waste», this complex may be considered as a workshop for the production of clay-plastics, and perhaps as a place of study.
 The discovered complex ought to be reconstructed as a place of residence for a large family group consisting of 4 small families, or a separate polygamous family. This social group specialized in the production of ceramic wares, serving a much larger social group.

Life Cycle Assessment of High-Performance Railway Infrastructure, Analysis of Superstructures in Tunnels and on Open Tracks

Almost 25% of the environmental pollution, measured by the indicator of global greenhouse emissions, is emitted by transport. Changes in the mobility behavior of the population will be essential if the 17 UN Sustainable Development Goals (SDGs) and the goals of the EU Commission’s Green Deal are to be attained. Accordingly, the existing infrastructure has to transform into a sustainable transport infrastructure through further optimizations in the future. Therefore, continuous optimizations and improvements of designs, materials, and processes are crucial to achieving long-term sustainability. This study investigates different superstructures with the method of life cycle assessment using the example of the emerging high-performance infrastructure at the Brenner Base Tunnel (BBT). The study analyzes all relevant life cycle stages (A1–C4) and validates different effects of service lifetimes of superstructure elements on the open track and in the tunnel. The results, which are presented in the form of GWP, AP, and NRCED, show that there is environmental reduction potential, especially in the stage of use. As more frequent modernization cycles and the associated remanufacturing of superstructure elements account for a significant proportion of the total environmental impact, lifetime extending optimization of products yields improvements in the ecological footprint.

Comprehensive Review of Methods to Assess Uncertainty in Health Economic Evaluations

Uncertainty assessment is a cornerstone in model-based health economic evaluations (HEEs) that inform reimbursement decisions. No comprehensive overview of available uncertainty assessment methods currently exists. We aimed to review methods for uncertainty assessment for use in model-based HEEs, by conducting a snowballing review. We categorised all methods according to their stage of use relating to uncertainty assessment (identification, analysis, communication). Additionally, we classified identification methods according to sources of uncertainty, and subdivided analysis and communication methods according to their purpose. The review identified a total of 80 uncertainty methods: 30 identification, 28 analysis, and 22 communication methods. Uncertainty identification methods exist to address uncertainty from different sources. Most identification methods were developed with the objective to assess related concepts such as validity, model quality, and relevance. Almost all uncertainty analysis and communication methods required uncertainty to be quantified and inclusion of uncertainties in probabilistic analysis. Our review can help analysts and decision makers in selecting uncertainty assessment methods according to their aim and purpose of the assessment. We noted a need for further clarification of terminology and guidance on the use of (combinations of) methods to identify uncertainty and related concepts such as validity and quality. A key finding is that uncertainty assessment relies heavily on quantification, which may necessitate increased use of expert elicitation and/or the development of methods to assess unquantified uncertainty.

Understanding the initial use stage of cement mortar lining in drinking water distribution systems: Silicon and aluminum as stability indicators

The cement mortar lining (CML) of commonly used ductile iron pipes can severely deteriorate the drinking water quality at the initial stage of use, but the behavioral characteristics of different elements release from the CML in this stage is still unclear. In this study, dynamic immersion experiments with new cement mortar lined ductile iron pipe reactors were conducted under different feed water hardness and alkalinity conditions. The results showed that the release of alkaline substances from the CML at the initial stage of use could strongly influence the pH of water, which consequently greatly impacted the release/precipitation behaviors of calcium, aluminum and silicon. The pH and aluminum concentration of the effluent water could reach 11.5 and 700 µg/L within 24 hr of hydraulic retention time, respectively, under conditions of relatively lower hardness and alkalinity. Due to the pH elevation, calcium carbonate precipitation could occur even at much lower feed water alkalinity. Whereas the aluminum and silicon could keep release from the CML in soluble form at different hardness and alkalinity levels, and their release rate depended on the amount of calcium carbonate precipitation. Thus, aluminum and silicon were more suitable as indicators of the corrosion intensity at the initial stage of CML use rather than the traditional calcium carbonate precipitation potential. Appropriate feed water hardness and alkalinity levels for mitigating the initial intense corrosion of CML were proposed: hardness > 40 mg/L (CaCO3), alkalinity > 100 mg/L (CaCO3).

Management of patients with inflammatory bowel diseases and extra-intestinal skin manifestations

Introduction. Clinical manifestations of inflammatory bowel diseases (IBD) are limited not only by the gastrointestinal tract syndromes, but also by a wide range of extra-intestinal manifestations, which include skin manifestations. Skin lesions in IBD occur in different forms. Some of them are associated with the activity of the main process, for example, gangrenous pyoderma. Others, such as psoriasis, are combined with pathogenetic factors common to IBD. Materials and methods. Three clinical observations of patients with IBD and extra-intestinal manifestations are presented: gangrenous pyoderma (case 1) and psoriasis (cases 2, 3). The stages of differential diagnostic search and treatment are described. The interleukin 12/23 inhibitor ustekinumab is prescribed to both bionaive patients (observations 1, 2), and to the patient who (observation 3) had high activity of the inflammatory process in the intestine and had received early treatment with GEBD. The extension of indications for use ustekinumab (ulcerative colitis, Crohn’s disease, psoriasis, psoriatic arthritis) of allows for its wider use in the treatment of patients. Conclusion. The interleukin 12/23 inhibitor ustekinumab has broad indications for use; its use allows to achieve a positive clinical, laboratory and endoscopic effect at the early stages of use. This effect has spread to skin manifestations, the reduction of which occurs in parallel with the healing of the intestinal mucosa.
