Abstract

Context
The practice of osteopathic manipulative treatment (OMT) varies substantially across nations. Much of this variability may be attributed to disparate international educational, licensing, and regulatory environments that govern the practice of osteopathy by nonphysicians. This is in contrast with the United States, where osteopathic physicians are trained to integrate OMT as part of comprehensive patient management.

Objectives
This study will analyze the factors associated with OMT use and its outcomes when integrated within the overall medical care for chronic low back pain (CLBP) provided by osteopathic physicians in the United States.

Methods
A retrospective cohort study was conducted within the Pain Registry for Epidemiological, Clinical, and Interventional Studies and Innovation (PRECISION) from April 2016 through April 2022 to study the effectiveness of OMT integrated within medical care provided by osteopathic physicians. The outcome measures, which included pain intensity, pain impact, physical function, and health-related quality of life, were assessed with the National Institutes of Health Minimum Dataset, Patient-Reported Outcomes Measurement Information System, and Roland-Morris Disability Questionnaire.

Results
A total of 1,358 adults with CLBP entered the cohort (mean age, 53.2 years; 74.4% female), 913 completed the final quarterly encounter, 348 were in various stages of follow-up, and 97 had withdrawn. Blacks (odds ratio [OR], 0.36; 95% confidence interval [CI], 0.21–0.63; p<0.001), cigarette smokers (OR, 0.56; 95% CI, 0.33–0.93; p=0.02), and nonsteroidal anti-inflammatory drug users (OR, 0.59; 95% CI, 0.43–0.81; p=0.001) were less likely to have utilized OMT in the multivariable analysis. Mean between-group differences among 753 participants with no OMT crossover and complete follow-up favored OMT: 1.02 (95% CI, 0.63–1.42; p<0.001) for pain intensity; 5.12 (95% CI, 3.09–7.16; p<0.001) for pain impact; 3.59 (95% CI, 2.23–4.95; p<0.001) for physical function, and 2.73 (95% CI, 1.19–4.27; p<0.001) for health-related quality of life. Analyses involving propensity-score adjustment and inclusion of participants with missing data yielded similar conclusions. None of 12 prespecified participant characteristics demonstrated an OMT interaction effect.

Conclusions
OMT integrated within medical care provided by osteopathic physicians for CLBP was associated with improved pain and related outcomes. Its use may be facilitated by the growing osteopathic physician workforce in the United States and adherence to relevant clinical practice guidelines.
Enhancing the wear performance of Ti-6Al-4V against Al2O3 and WC-6Co via TiBn layer produced by boriding
Authors: İpek Ayvaz Safiye 
Published: February 2023

Abstract
In this study, mechanical and tribological properties of the borided dual-phase α + β type Ti6Al4V titanium alloy were examined. For this purpose, Ti6Al4V alloy samples were borided for 6 h at a temperature of 1100 °C by the powder-pack boriding process. As a result of boriding, a boride layer consisting of TiB2 with a thickness of max ∼25 µm and TiB phases with a thickness of max ∼10 µm was obtained on the Ti6Al4V sample surfaces. As a result of the boride layer’s nanoindentation tests carried out using the Berkovich indenter, it was found to have an elastic modulus of 534.255 GPa and a hardness of 36.537 GPa. Wear tests were carried out using the pin-on-disc method under a load of 10 N and with a sliding distance of 1000 m. Whereas the dominant type of wear in non-borided samples was abrasive wear, oxidative mild wear was generally observed in borided samples. In borided samples, as a result of becoming of surface smoother by hard asperities breaking and increasing the actual contact area, the friction coefficients increased. It was determined that with boriding, the wear performance of Ti6Al4V alloy improved ∼46.8 times against the Al2O3 counterpart and ∼4.57 times against WC-6Co counterpart.

Published: February 2023

AbstractTwisted variable channel angular pressing (TV-CAP) is a novel method. While it combines the advantages of equal channel angular pressing (ECAP), twist extrusion and direct extrusions, also it eliminates the disadvantages of these methods. Finite element analysis was also carried out in order to examine the design parameters, material flow and examine the effective strain values. Hardness and tensile tests were performed to examine the effect of TV-CAP on the mechanical properties of AA6082. In addition, optic microscope, SEM and TEM images were taken respectively and XRD, EDS and EBSD analyses were accomplished in order to investigate the microstructural analysis. As a result of this study, it has been observed that the material has hardened approximately 3 times compared to the annealed material and became 1.5 times stronger in terms of ultimate tensile strength. It was also concluded that, this new method is more efficient than twist extrusion and multi-pass equal channel angular pressing processes.

Published: February 2023

Abstract
Delamination is the most important problem encountered in drilling composite materials. This problem can be minimized by optimizing the cutting parameters. In this study delamination behavior of glass/carbon/aramid fiber reinforced hybrid composite was investigated during the drilling operation. Experiments were planned according to Taguchi’s L27 orthogonal array. Cutting velocity (20 m min−1, 40 m min−1, and 60 m min−1), feed rate (0.04, 0.08, and 0.12 mm rev−1), and cooling type (wet, air, and dry) were selected as cutting parameters. Thrust force was measured during the drilling operation, and the delamination factor for entrance was calculated after the tests. Optimization of the parameters was evaluated using the signal/noise ratio approach. The effectiveness of parameters on results was determined by analysis of variance (ANOVA). In addition, regression equations were obtained with the response surface method (RSM). According to the optimization results, the thrust force can be reduced with low cutting velocity and low feed rate under dry conditions. It was concluded that low cutting velocity and the feed rate should be applied under dry conditions to reduce delamination.

Published: February 2023

Abstract
AISI 1040 and AISI 304 steel plates of 10 mm were joined without pretreatment by double-sided TIG arc welding (DSAW). Joints were manufactured by using welding currents of 420, 440, and 460 A. The microstructural variations in the interface of the weld samples were defined by optical microscopy, scanning electron microscopy, energy dispersive spectroscopy and microhardness analysis. V-notch impact and tensile tests were done to detect the weld strength of the weld samples. In DSAW welding of different steels, a full penetration joint was achieved without opening the weld edge. The current intensity had a major effect on the symmetrical and hourglass shape in welds. Welding at 460 (A) showed acceptable joint quality. Tensile and impact energy quantities of welded joints had significant ratios. Fractures in the weld metal of the samples were ductile mode.
An Ontologically Nihilist Critique of Graham Harman’s Ontological Liberalism
Authors: Lovasz Adam 
Published: February 2023

Abstract
In Graham Harman’s realist philosophy, which I call “ontological liberalism,” all objects are considered equal, there being no unbridgeable gap between various modes of being. Every object is a unique individual, endowed with a positive being. Any privileging of a certain class of objects over other classes of objects is invalidated. An object is composed of its relations, summarized under the heading of what Harman calls “sensual qualities,” while objects also contain mutually inaccessible essences. Supposedly, every object may be characterized by the duality of relationality and substantiality. According to ontological liberalism, all objects exist. In this essay, I propose an ontological nihilist critique of Harman’s liberal ontology. We cannot exclude the possibility of every object being equally nonexistent. Appearances could pertain all the way down, with no final substance at the end of the infinite chain of appearances. Building on insights gleaned from Jan Westerhoff’s defence of ontological nihilism, I propose a nihilist reconfiguration of Harman’s ontological liberalism. If objects and relations are empty and reality is made of appearances all the way down, no underlying objective essence can or should be posited. Because relations are without basis, lacking in substance, nothing exists, nothing happens, and no objects exist.

Abstract
Membrane-aerated biofilm reactor (MABR) has been considered as an innovative technology to solve aeration issues in conventional bioreactors. MABR uses a membrane to supply oxygen to biofilm grown on the membrane surface. MABR can perform bubbleless aeration with high oxygen transfer rates, which can reduce energy requirements and expenses. In addition, a unique feature of counter-diffusion creates a stratified biofilm structure, allowing the simultaneous nitrification–denitrification process to take place in a single MABR. Controlling the biofilm is crucial in MABR operation, since its thickness significantly affects MABR performance. Several approaches have been proposed to control biofilm growth, such as increasing shear stress, adding chemical agents (e.g., surfactant), using biological predators to suppress microorganism growth, and introducing ultrasound cavitation to detach biofilm. Several studies also showed the important role of membrane properties and configuration in biofilm development. In addition, MABR demonstrates high removal rates of pollutants in various wastewater treatments, including in full-scale plants. This review presents the basic principles of MABR and the effect of operational conditions on its performance. Biofilm formation, methods to control its thickness, and membrane materials are also discussed. In addition, MABR performance in various applications, full-scale MBRs, and challenges is summarized.

Published: February 2023

Розпочата РФ війна проти України має цивілізаційний характер, є протистоянням між європейською і євразійською цивілізаціями. Війна спричинила поштовх до глобальних змін у світовому геополітичному і геоекономічному порядку. Світ стає двополярним – США і Китай очолять свої полюси, які віддзеркалюють демократію й автократію. Щоб зайняти в цьому новому світі гідне місце, Україна повинна відродитись у європейській якості свого політичного, соціального і економічного життя.
Визначено, що економічне відродження потребує в першу чергу відтворення людського і соціального капіталу країни, адекватного європейським цінностям. Обґрунтовано культурний феномен нації як основу їх відтворення. У формуванні якісного людського і соціального капіталу вирішальне значення має освіта як складова національної культури. Проаналізовано стан сфери вищої і професійної освіти, визначено основні напрями її реформування в контексті повоєнної розбудови держави.
Констатовано, що Україна повинна активно відтворювати свій соціальний капітал як здатність громадян до колективних дій заради досягнення спільної мети – вступу до ЄС і НАТО. Для цього державою мають бути створені умови для формування високого рівня довіри як між громадянами, так і громадян до державних структур. Обґрунтовано, що для цього потрібна нові структура і зміст державного управління, головним у якому має стати мінімально можливий рівень централізованого прийняття рішень і управління їх втіленням. Доведено важливість інформаційної політики для стимулювання відродження України, метою якої має бути переконання світу, що Україна є потенційно важливим суб’єктом міжнародних економічних і політичних відносин.

ABSTRACT
Following the Mw 6.0 Amatrice earthquake on 24 August 2016 in central Italy, the Emersito task force of the Istituto Nazionale di Geofisica e Vulcanologia installed a temporary seismic network focusing on the investigation of amplification effects at municipalities located on topographic reliefs. Fourteen stations were installed at three sites: Amandola, Civitella del Tronto, and Montereale. During the operational period, stations recorded about 150 earthquakes with Mw up to 4.7. Recorded signals were analyzed calculating the horizontal-to-vertical spectral ratios at single station, using both ambient noise and earthquake waveforms, as well as standard spectral ratios (SSRs) to a reference site. To robustly estimate site amplification at each station of the site amplification effect at each station, the influence of backazimuth and epicentral distance is investigated. With the aim of reproducing the observed amplification pattern, 2D numerical simulations were performed on a section orthogonal to the topography major axis, constrained through in situ geological investigations and geophysical surveys. Although at Montereale site no clear amplification effects were observed, at Amandola site, all stations on the relief consistently detected significant peaks at about 4 Hz and along N120–150 azimuth. At Civitella del Tronto, a proper reference station is missing, implying a misleading of site response evaluation in terms of SSRs. Moreover, even if all stations show amplification in the frequency band 1–3 Hz, the direction of the maximum amplification varies from northeast to northwest. At the three sites, observations were successfully reproduced by 2D numerical models, the latter suggesting that topography alone cannot reproduce data, and the interplay with subsoil velocity structure is needed to produce a clear amplification effect. We conclude that according to the previous articles, rather than the sole topography convex shape, the geophysical structure has often a predominant role in controlling the observed amplification pattern on topography.

En el ámbito rural alto andino de Perú, es importante el monitoreo de la calidad de agua según las metas e indicadores del desarrollo sostenible correspondientes a su disponibilidad, su accesibilidad, y que éstas estén libres de contaminación fecal y química. Al respecto, existe información reducida sobre la calidad del agua de consumo humano que no apoya a los involucrados en la correcta gestión del agua con estrategias de intervención eficientes.
Por tanto, el objetivo de esta investigación fue contribuir con información actualizada sobre el estado de la calidad de agua de seis comunidades rurales alto andinas del departamento de Huancavelica en el Perú, correspondientes a parámetros fisicoquímicos y microbiológicos. Las comunidades fueron Antaccocha, Huaylacucho, Pampachacra, Pueblo Libre, San Gerónimo y Sachapite ubicadas entre los 3782 m.s.n.m. y 4196 m.s.n.m que albergan un total de 17 reservorios de agua donde se realizó el estudio. La evaluación fisicoquímica abarcó variables como la turbidez, conductividad eléctrica, pH, total de solidos disueltos y potencial de oxidación; el microbiológico contempló la evaluación del Echericha Coli, coliformes termotolerantes y fecales. Como resultado, tan solo 1/17 (5,9%) punto de muestreo, ha superado el valor límite de turbidez de 5 NTU permitido por la normativa peruana; los demás parámetros se encuentran dentro del umbral permitido. Respecto a los parámetros microbiológicos (Echericha Coli, coliformes termotolerantes y fecales), 4/17 (23,5%) puntos de monitoreo han superado el valor límite permitido por el reglamento de agua de consumo humano; asimismo, se ha encontrado que guardan relación estos tres parámetros.

Purpose of the study: The present study aims to show Michel Foucault's concept of power in the selected novel Khushwant Singh's Train to Pakistan (1956), and the theory of power is applied in a way that how power is present in the character Juggut Singh.
Methodology: The present research is qualitative in its approach, exploratory in nature, and close reading textual analysis is used to interpret the data.
Main Findings: The interpretation of the components of Power by Michel Foucault in Khushwant Singh's novel Train to Pakistan (1956) has been focused that resulted in the hidden and invisible form of power is experienced without knowing the power, but it dominates the individual's behaviour and hidden attitude. So, such a form of power is constructed in the child's character through social norms and discourses at the very start of his life.
Applications of the study: The paper helps to identify in future studies how Michel Foucault's concept of power in other literary genres and how power is applied in different ways and operated in the contexts of literary genres.
Novelty/Originality of the study: The study is based on the novelty of the idea based on power theory. If the child is not stealing or not doing something wrong, then it does not mean that he has a fear of punishment, but he would not want to steal because this thing is inside his psyche. That's why he is unwilling to steal because his inside power is not allowing him to do so. Therefore, the research identifies Michel Foucault's concept of power in the selected novel of Khushwant Singh Train to Pakistan (1956).

Published: February 2023

SummaryAim. To study the antagonistic activity of bacteria of genera Bacillus, Priestia and Paenibacillus at different conditions of cultivation. Methods. Antagonistically active spore-forming bacteria isolated from deep-sea bottom sediments of the Black Sea were used for the study. Determination of thermotypes was performed using the results of analysis of fatty acid profile parameters. Antagonistic activity to test strains of bacterial opportunistic pathogens was detected by the method of agar blocks on Gauze № 1 and Nutrient Agar media at different cultivation temperatures. Results. Aerobic bacilli of genera Bacillus, Priestia and Paenibacillus of all three thermotypes – thermotolerants, mesophiles and psychrotrophes, in general show lower antagonistic activity when cultured at 37 °C on both media, except for a marked increase in psychrotrophe antagonistic activity at 37 °С on Gauze № 1. Conclusions. It was established that belonging to a certain thermotype affects the character of the antagonistic activity of sporeforming bacteria. The antagonistic activity of mesophilic and thermotolerant bacteria at a higher temperature of cultivation is lower, and that of psychrotrophic bacteria at a higher temperature and on Gauze № 1 medium is higher.
