Published: May 2023

Background: The purpose of this proof-of-concept feasibility study was to determine if spike-triggered intraspinal microstimulation (ISMS), a form of activity dependent stimulation (ADS), results in improved motor performance in an ambulatory rat model of spinal cord injury (SCI). Methods: Experiments were carried out in adult male Sprague Dawley rats with moderate thoracic contusion injury. Rats were assigned to one of two groups: Control or ADS therapy. Four weeks post-SCI, all rats were implanted with a recording microelectrode in the left hindlimb motor cortex and a fine-wire stimulating electrode in the contralateral lumbar spinal cord. ADS was administered for 4 hours/day, 4 days/week, for 4 weeks. During therapy sessions, single-unit spikes were discriminated in real time in the hindlimb motor cortex and used to trigger stimulation in the spinal cord ventral horn. Control rats were similarly implanted with electrodes but did not receive stimulation therapy. Results: Motor performances of each rat were evaluated before SCI contusion, once a week post-SCI for four weeks (prior to electrode implantation), and once a week post-conditioning for four weeks. Basso, Beattie, and Bresnahan (BBB) locomotor scores were significantly improved in ADS rats compared to Control rats at 1 and 2 weeks after initiation of therapy. Foot fault scores on the Horizontal Ladder were significantly improved in ADS rats compared to pre-therapy ADS and Control rats after 1 week of therapy and recovered to near pre-injury scores after 3 weeks of therapy. The Ledged Beam test showed deficits after SCI in both ADS and Control rats but there were no significant differences between groups after 4 weeks of ADS therapy. Conclusions: These results show that chronic stimulation after spinal cord injury using a methodology of spike-triggered ISMS enhances behavioral recovery of locomotor function as measured by the BBB score and the Horizontal Ladder task. However, it is still uncertain if the behavioral improvements seen were dependent on spike-triggered ISMS.

Challenges of evidence based medicine in clinical practice
Authors: Pradhan Nabees Man Singh
Published: May 2023

Evidence-based medicine (EBM) is an approach by clinicians that involves conscientious, explicit, and judicious use of available evidence in deciding on the care of individual patients.1 With the digital revolution and easy access to the available literature, EBM , which was not very practical a few decades ago due to the difficulty in assessing the resources, has been practiced with increasing success nowadays, even in the developing world. The revolution brought about by EBM with regard to the practice of medicine over the past few decades has been remarkable.2 Because of the individualized treatment based on external evidence, EBM leans towards justifying the action with accountability; hence being labeled as the fourth revolution in American Medicine.3

Published: May 2023

Hardmetal coating compositions containing both WC and Cr3C2 are less intensively studied than WC-Co(Cr) and Cr3C2-NiCr. In particular, compositions with Cr3C2 as the main phase are relatively new in the market. In this contribution, two commercial agglomerated and sintered feedstock powders with similar compositions (42Cr3C2-42WC-16Ni and 45Cr3C2- 37WC-18NiCoCr) were studied. Both powders differ in their porosity and the melting behavior, as was found by DSC experiments. Coatings were deposited with a liquid-fueled HVOF process (JP 5220). Optimization of the spray conditions was evaluated with five different spray parameter sets. Coating microstructures and phase compositions, as well as microhardness HV0.3 and abrasion wear resistance were less influenced by the spray parameter sets. At the same time, significant differences in deposition efficiency between the two compositions were observed, which might be related to the differences in the melting behavior of the compositions and the powder porosity. However, coating microhardness and abrasion wear resistance were similar for each of the spray parameter sets. Coating microstructure and phase composition were studied with a focus on the interaction between Cr3C2 and WC and will be discussed in detail.

Explores science and social science early career researchers’ (ECRs) perceptions and experiences of peer review, seeking also to identify their views of any pandemic-associated changes that have taken place. Data are drawn from the Harbingers-2 project, which investigated the impact of the pandemic on scholarly communications. Peer review, one of the activities covered, is singled out as it proved to be the activity of greatest concern to ECRs. Findings are obtained from interviews, which covered around 167 ECRs from China, France, Malaysia, Poland, Russia, Spain, UK and US, supplemented by an international survey that took the data out to a bigger and wider audience for confirmation and generalisation. Results obtained are enhanced by comparisons with pre-pandemic evidence yielded by Harbingers-1, the forerunner of the present study, and anchored in an extensive review of the literature. Main findings are: 1) most ECRs were experienced in peer review, both as reviewers and authors, but few had formal training; 2) half the ECRs had a lot or some reservations as to whether peer review vouches for the trustworthiness of research; 3) inadequate reviewers and slow processes were the main peer review associated problems; 4) there was a strong feeling that some kind of compensation, whether monetary or reputational, could help in dealing with these problems; 5) the pandemic impacted most on the speed of processing, with the majority of ECRs saying it had slowed the process; 6) nearly everyone thought that any pandemic-induced impacts would be temporary.

Published: May 2023

Study Design: Retrospective cohort.Purpose: To assess preoperative arm pain severity influence on postoperative patient-reported outcomes measures (PROMs) and minimal clinically important difference (MCID) achievement following single-level anterior cervical discectomy and fusion (ACDF).Overview of Literature: There is evidence that preoperative symptom severity can affect postoperative outcomes. Few have evaluated this association between preoperative arm pain severity and postoperative PROMs and MCID achievement following ACDF.Methods: Individuals undergoing single-level ACDF were identified. Patients were grouped by preoperative Visual Analog Scale (VAS) arm ≤8 vs. >8. PROMs collected preoperatively and postoperatively included VAS-arm/VAS-neck/Neck Disability Index (NDI)/12-item Short Form (SF-12) Physical Composite Score (PCS)/SF-12 mental composite score (MCS)/Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF). Demographics, PROMs, and MCID rates were compared between cohorts.Results: A total of 128 patients were included. The VAS arm ≤8 cohort significantly improved for all PROMs excepting VAS arm at 1-year/2-years, SF-12 MCS at 12-weeks/1-year/2-years, and SF-12 PCS/PROMIS-PF at 6-weeks, only (p ≤0.021, all). The VAS arm >8 cohort significantly improved for VAS neck at all timepoints, VAS arm from 6-weeks to 1-year, NDI from 6-weeks to 6-months, and SF-12 MCS/PROMIS-PF at 6-months (p ≤0.038, all). Postoperatively, the VAS arm >8 cohort had higher VAS-neck (6 weeks/6 months), VAS-arm (12 weeks/6 months), NDI (6 weeks/6 months), lower SF-12 MCS (6 weeks/6 months), SF-12 PCS (6 months), and PROMISPF (12 weeks/6 months) (p ≤0.038, all). MCID achievement rates were higher among the VAS arm >8 cohort for the VAS-arm at 6-weeks/12-weeks/1-year/overall and NDI at 2 years (p ≤0.038, all).Conclusions: Significance in PROM score differences between VAS arm ≤8 vs. >8 generally dissipated at the 1-year and 2-year timepoint, although higher preoperative arm pain patients suffered from worse pain, disability, and mental/physical function scores. Furthermore, clinically meaningful rates of improvement were similar throughout the vast majority of timepoints for all PROMs studied.

Published: May 2023

Anterior cervical corpectomy and fusion is considered the mainstay of surgical treatment in cervical pathology. Expandable and nonexpandable cages are preferred over autogenous bone graft because of donor-related morbidity. However, the choice of the cage type remains a debatable topic as studies report conflicting results. Thus, we evaluated the outcomes of expandable and non-expandable cages following cervical corpectomy. Studies were searched in various electronic databases (MEDLINE, PubMed, EMBASE, CINAHL, Scopus, and Cochrane) between 2011 and 2021. Forest plot was made to compare the radiological and clinical outcomes between expandable and non-expandable cages following cervical corpectomy. Altogether, 26 studies (1,170 patients) were included in the metaanalysis. The mean change in segmental angle was significantly greater in the expandable cage group than in the non-expandable cage group (6.7° vs. 3.0°, p <0.001). The mean subsidence rate was lower in the expandable cage group (6% vs. 41%, p <0.001). The mean fusion rate was lower (93% vs. 98%, p =0.06) and the mean displacement rate was significantly higher in the expandable cage group (29% vs. 5%, p <0.05). The mean reoperation rate was higher in the expandable cage group (16% vs. 2%, p >0.05). The improvement in segmental angle is better with expandable cages. Higher subsidence is a major problem with non-expandable cages, but it seems to be beneficial as evidenced by the high fusion rate and minimal effect on clinical outcome in patients with this cage.

The article consides the problems of Lviv’s newest sacred architectural buildings, namely their functional qualities. It is proven that among the main reasons why religious people rarely attend liturgies can be a lack of time or a general reluctance to visit the church, giving priority to other matters. The following principles of the designing of church educational institutions are given: denominationalism and ecumenism; multi-education; sacredness; worldliness; inclusiveness; flexibility and mobility; traditionalism and modernity. The main functional zones are distinguished, which include the entrance zone, sanctuary, entertainment and recreation, educational, dining, residential, commercial, administrative, technical, household, exhibition and auxiliary groups of objects. The necessity of searching for new ways and means of spreading spiritual knowledge in society is indicated. It requires new methods and approaches in the design of institutions of religious activity. Special attention is paid to the needs of people with disabilities. Public spaces are divided into functional and cultural and educational spaces. Types of location of public spaces in churches are described, they are: part of the floor, in a specially built building, with a specially decorated entrance, under the open sky, part of the building. The topic of public space in temples is considered. It is noted that the building of the spiritual retreat center, which combines various social functions, is designed in such a way as to ensure the comfort of visitors and the smooth operation of all functional processes. The internal organization of space plays an important role in this. The interior is the final addition to create an artistic image and overall harmonious composition. In the study, the functions of sacred architecture are determined: (commercial function, social/public function, religious function, etc.). It is determined that the church, as a building, is historically something more than a religious building. It is proposed to design the temple as multifunctional and to develop it not only as a religious building, but also as a public area. Recommendations on the architectural solution of sacred buildings are given, an overview of individual examples of modern sacred architecture in Lviv is given. The functional properties of modern churches in Lviv are analyzed.
STRESS-DEFORMED STATE OF VERTICAL CILINDRICAL METAL SHELL UNDER TEMPERATURE CLIMATE IMPACT
Authors:   Odessa State Academy of Civil Engineering and Architecture, Zhdanov А.А. , Petrov V.N. ,   National University "Odessa Polytechnic"
Published: May 2023

Vertical cylindrical containers are widely used for storage of granular bulk materials. The enclosing side surface of such containers is made in the form of cylindrical metal circular shells with a wall thickness that is constant or piecewise constant along the height of the shell. Known designs for storage of bulk materials of the reservoir type with the installation of a cylindrical shell on the annular foundation with hinged fixed attachment of the shell to the foundation. Thin-walled shells are made suspended from the supporting structures of the storage facilities. To stabilize the cylindrical shape of the shell and its position in space, the suspended shells are pre-tensioned in the vertical direction. During operation, storage facilities are empty and filled with bulk materials, exposed to the environment in the form of wind and temperature climatic influences. The object of study of this work is the enclosing structures of storages of granular bulk materials in the form of vertical circular cylindrical thin-walled metal shells, in the general case of piecewise constant thickness, subject to temperature and climatic influences of the environment ‒ changes in the temperature of the outside air, direct and diffuse solar radiation. The subject of the study is the components of the stress-strain state of the shell due to changes in temperature and climatic influences. The performed studies of the temperature fields of storage shells on models and full-scale objects made it possible to substantiate the assignment of the temperature field of cylindrical storage shells by Fourier series. One-sided solar heating of cylindrical storage shells completely illuminated by the sun induces in the shell wall a flat temperature field symmetrical with respect to the normal of incidence of sunlight, which can be represented by a Fourier series with five terms of the cosine expansion series. In the presence of a structure located next to the shell, which covers half of the shell along the entire height in the circumferential direction, the temperature field is described by a Fourier series containing 10 harmonics of expansion in sines and cosines. The small thickness of the shell, the significant radius of curvature of the shells, the large thermal diffusivity of metals provides a small variability of the temperature of the shell over the thickness, the ability to describe the stress-strain state of the shell, the momentless theory and a simple edge effect.

The analysis of fire-resistant materials for wooden building structures was carried out and the need for the development of reliable means of protection to inhibit the ignition process and the spread of flame on the surface of the building structure was established. Therefore, there is a need to determine the conditions for the formation of a barrier for thermal conductivity and to establish a mechanism for inhibiting the transfer of heat to the material. According to experimental data, it was established that the untreated sample ignited for 52 s, the flame spread throughout the sample within 100 s, on the other hand, the sample, fire-protected with the impregnation solution BS-13, ignited for 570 s, the flame spread over the surface only in the first section, the maximum temperature of flue gases was 86 °C, and the flammability index was 3.42. For the sample protected by the "FIREWALL-WOOD" coating, the fire did not occur, because a protective layer of pinocoke was formed on the surface, the flammability index was 0. As a result of research, it was proven that the process of temperature inhibition consists in the decomposition of flame retardants under the influence of temperature with the absorption of heat and the release of non-combustible gases. Formation of soot-like products on the surface of natural combustible material and thermal insulation of a wooden structure. Thanks to this, it became possible to determine the conditions of fire protection of wood, by forming a barrier for thermal conductivity during the decomposition of varnish into foam coke. Experimental studies have confirmed that a sample of wood covered with a fire-resistant coating has withstood temperature effects under the influence of heat flow for 600 seconds. This gives reason to assert the possibility of targeted regulation of wood fire protection processes through the use of fire retardant coatings capable of forming a protective layer on the surface of the material that inhibits the rate of wood burning.

Published: May 2023

The article examines the question of rethinking the architectural qualities of a boarding-type building in the domestic discourse. The evolution of views on the main priorities of the institutions of alternative care for children is traced. Also have been determined the key role of Ukraine's adaptation of the deinstitutionalization strategy in the development of approaches to the interpretation of the residential building. Within the chronological limits of the last 30 years, have been highlighted three stages of transformation of the theoretical opinion regarding the planning and spatial structure of the care institutions. One of them is related to the inertia of functionalist approaches, the priority of which were aspects of physical health and ensuring the appropriate social level. The second stage reflects the awareness of the inadequacy of vital pragmatics and the search for different ways of influencing social adaptation and the psychology of positive interaction. At the third stage, a gradual transition to the understanding of the residential building as a small scale structure with a capacity oriented to the family type of cohabitation is noted. This opened up the prospect of a significant rethinking of the methodology of designing alternative care facilities, searching for different methods of adapting existing buildings and designing new ones on the basis that, in general, correspond to the so-called deinstitutionalization strategy adopted by Ukraine in 2017. In connection with this, there is a question of assessing the current state of domestic scientific opinion regarding the design of residential institutions. On the basis of the methods used, it is compared with the modern understanding of the facility for alternative care in Western countries, where the strategy of deinstitutionalization has a longer history and has given certain theoretical and practical results. In general, it was established that the domestic discourse in this field, despite the relatively small number of works, corresponds to the main trends in the evolution of ideas about the care environment for orphans and children with special needs. A number of features have been identified that are characteristic of current domestic ideas in the field of care and can become the basis for our own tradition of architectural interpretation of children's residential institutions.

The article decribes the issues of numerical experimental research related to the determination of the magnitude of the waves damping when they overflow through the upper structure of a protective hydraulic structure (PHS) of an incomplete vertical profile. The presented studies were carried out in order to verify the results of physical experimental studies. Physical experimental studies were carried out in the hydrowave laboratory of the Hydrotechnical Construction Department of the Odessa State Academy of Civil Engineering and Architecture. The numerical model of the design of the PHS of an incomplete vertical profile was made similar to the conditions of the full-scale section of the coast of the Odessa Bay. The design of the PHS of an incomplete vertical profile is supposed to be located at a distance L = 200 (m) from the coastline of the protected area. At the location of the designed protective structure, the estimated water depth d = 4.0 (m). Having built the rays of refraction and transformation of waves when the waves approach the designed structure, the calculated wave height will be h = 2.4 (m); average wavelength λ = 24.5 (m); the elevation of the upper structure of the PHS with an incomplete vertical profile relative to the calm water level was taken equal to Δ Н = +1.0 (m), the width of the superstructure of the protective structure В = 4.0 (m). As a result of numerical experiments, the height of the damped wave when it overflows through the upper structure of the PHS structure with an incomplete vertical profile onto the protected water area was htr = 0.6 (m). The results of numerical simulation differ by – 3.3% from the wave height obtained during the physical experiment. The use of PHS structures of an incomplete vertical profile, in order to protect the water areas of seaports, as well as elements of the coastal infrastructure of sea cities, will increase the investment attractiveness of creating new projects of protective and coastal protection structures, due to a decrease in the elevation of the surface part.
Enacting “Bottom-up” Solidarity in Labor Market Integration for Refugees in England

Published: May 2023

This article examines the role that third sector organizations (TSOs) play in supporting refugees’ access to the labor market in England. TSO practices are conceptualized through the notion of “bottom-up” solidarity. Data gathered through interviews with refugees and representatives from charities, social enterprises, and public authorities are used to identify how TSO actors enact bottom-up solidarity and, in turn, facilitate integration of refugees into the labor market. The findings show how labor market transition is built on the transformation of the wider circumstances faced by refugees. Data also demonstrates how the creation of direct employment opportunities, coupled with intermediation and trust brokerage, and alongside episodic and extended coaching, is key to enacting “bottom-up” solidarity.

Het Waddenfondsproject Súd Ie beoogt economie, recreatie en ecologie te combineren en te verbinden. Het project kent drie fasen, in fase 1 en 2 van het uitvoeringsprogramma van het project Súd Ie zijn o.a. vispassages, natuurvriendelijke oevers en paai- en opgroeigebieden aangelegd. Daarnaast worden langs de Súd Ie gelegen (brakke) polders en natuurgebieden hersteld en toegankelijk gemaakt voor diadrome vissoorten, veelal driedoornige stekelbaars en paling. Deze maatregelen zorgen ervoor dat binnenkort de deur vanaf het Lauwersmeer open staat en het huis (lees habitat) voor de vis op orde is. Daardoor is een duurzame ecologische verbinding met de Waddenzee in dit gebied hersteld. Het project Impuls Diadrome Vissen, onderdeel van fase 3, richt zich specifiek op het achterland, de twee geselecteerde proeftuinen Eanjumerkolken en Kolken Noord. De kernvraag hierbij luidt: 'Zijn de langs de Súd Ie optrekbaar gemaakte brakke (natuur)gebieden van meerwaarde voor diadrome vissoorten en hoe wordt hier gebruik van gemaakt?'. Met een uitgebreid monitoringssysteem wordt naar het antwoord op deze vraag gezocht. Deze rapportage bevat de resultaten van de monitoring in het najaar van 2020, waarbij het habitat en de visstand van de polders Kolken Noord en Kolken Zuid (Eanjumerkolken) nader is bekeken. Uitvoeren van een pilot onderzoek naar de visstand en habitat van proefgebieden in het Súd Ie-gebied. Doelsoorten zijn driedoornige stekelbaars en paling. Deze kennis wordt gebruikt voor de bepaling van de aard en wijze van de nulmonitoring.
Сказание церковное
Authors: Афанасьева Татьяна
Published: May 2023

В статье описывается важный памятник старославянской литературы, посвященный толкованию литургии, а именно перевод Historia Ecclesiastica, приписываемый патриарху Герману. Затрагиваются вопросы, связанные с историей славянского текста, его локализацией и атрибуцией епископу Преславскому Константину, а также его соответствия греческому оригиналу. Дан обзор всех славянских списков Сказания церковного и описана его дальнейшая судьба в восточнославянской рукописной традиции. На русской почве текст претерпел значительные сокращения и затем в этом новом виде был включен в сборник «Толковая служба», ставший в XIV веке отдельной главой русского Номоканона (Кормчей книги). До реформ патриарха Никона эта статья была основным источником по символике служения литургии. У южных славян «Сказание церковное» не получило широкого распространения (сохранились только рукописи 13—14 вв.), текст в дальнейшем не переписывался.
