BEARING CAPACITY CALCULATION OVER INCLINED SECTIONS OF A TWO-LAYER T-BAR ELEMENT WITH HIGH-STRENGTH CONCRETE IN A COMPRESSED ZONE WITHOUT TRANSVERSE REINFORCEMENT
Authors: Rogatnev Y. F. , Panfilov D. V. , Sokolov O. O.
Published: February 2023

Statement of the problem. The study discusses the issue of determining the bearing capacity for inclined sections of two-layer bending T-section elements with high-strength concrete in a compressed zone. Normative documentation for the calculation and design of reinforced concrete structures does not take into account the flanges of T-section to determine the bearing capacity. The problem was to define the influence of the mechanical characteristics of concrete of the flanges on the bearing capacity of the elements. Elements without transverse reinforcement and with different classes of concrete in the flange are considered. Results. According to the results of numerical modeling, characteristic patterns of the stress-strain state at the limit state of the bearing capacity of the elements have been established. The relations of the bearing capacity on the span of the cut and the class of concrete compression of flange are given. The values of the bearing capacity of the elements were obtained without taking into account the overhangs of the shelf according to SP 63.13330.2018 and EN 1992-1-1. Conclusions. It is found that, contrary to the logic of the normative documentation SP 63.13330.2018 and EN 1992-1-1, the overhangs of the flange of the T-section beam affect the bearing capacity of the element along the inclined section. Increasing the physical and mechanical properties of concrete separately from the two-layer element forms even greater reserves of bearing capacity.

Published: February 2023

Statement of the problem. The article considers the task of developing a modern theory for creating technologies for processing large-tonnage dispersed materials and technogenic products using non-firing technologies in the industry and road construction as structural layers of roads. Results. We applied the Deryagin-Landau equation, supplemented by introducing the potential of induction and dispersion intermolecular interaction in diffuse layers of composite particles to predict the strength characteristics of building materials. We propose the diagnostics of raw materials, taking into account the energy of dehydration, which makes it possible to predict their binding properties and the ability to contact-condensation hardening. We obtained a regression dependence of the change in the strength of the resulting material on technological parameters and showed that the main contribution to the strength characteristics is made by pressing pressure, temperature and mixing time. Conclusions. We proved the effectiveness of using a mathematical model for optimizing the process of obtaining lime-sand phosphogypsum material. We showed the prospects for the application of the proposed provisions of the theory of aggregative stability of dispersed mineral materials in the creation of new materials with desired properties that meet the requirements of modern construction of buildings, structures and pavement bases.

Strategic autonomy of the European Union in the politics of France before and after Russian aggression in Ukraine
Authors: Helnarska Karolina Julia
Published: February 2023

The aim of the article is to present the proposal by France as the initiator of the development of the strategic autonomy of the European Union and the politics of France before and after Russian aggression in Ukraine. The idea of the European Union’s involvement in the defence sphere has been with us for years; however, the concept of strategic autonomy is differently understood in the Member States of the European Union. For this reason, the following research questions were formulated: How is the strategic autonomy of the European Union understood in the politics of France? What is the position of France in reference to developing a “Europe of defence” for the European Union’s security and defence policy? How does Russia’s aggression in Ukraine affect the development of the European Union’s strategic autonomy in France’s policy? How does Russia’s aggression in Ukraine affect France’s position on the spread of the EU’s strategic autonomy? It would seem that the outbreak of the war in Ukraine constitutes an existential test for strategic autonomy.

Authors: Bhattacharjee Somnath , Mandal Arindam , Debnath Rabin , Majumder Snehamoy
Published: February 2023

Experimental investigation of the effect of bluff bodies on the turbulent flow through an asymmetric diffuser has been carried out. The rectangular diffuser is designed and made keeping similarity to that used by Buice and Eaton, [1], having an inclination angle of 10°. Three geometrical configurations have been selected for the experimentation. (I) At first the experiment has been carried out for the validation of the present results with Buice and Eaton, [1], placing no bluff body at all. (II) Thereafter measurements have been carried out by placing a single bluff body on the horizontal floor of the diffuser to estimate the effect of the bluff body on the downstream flow. (III) Finally, two identical bluff bodies are placed on the horizontal floor of the diffuser and experimental work has been carried out in order to investigate the effect of the existence of two bluff bodies on the downstream flow through the diffuser. The present results agree well with the results of Buice and Eaton, [1], to show that the recirculation zone appears just adjacent to the inclined plane when there is no bluff body in a diffuser. Also, the detailed investigation for velocity of flow field, distribution of skin friction factor along with uncertainty analysis as well as the correlation between friction factor and Reynolds Number have been carried out in the research paper.

Decomposing 'As If'
Authors: Rett Jessica , Starr W.
Published: February 2023

‘As if’ constructions have been analyzed as only verbal (Bücking 2017) or idiomatic (Bledin & Srinivas 2019, 2020). We argue that ‘as if’ constructions have the same distribution as any clausal similative (i.e. any ‘as’ construction): they can associate with verbal arguments or propositions. And we argue that ‘as if’ constructions are a common and productive cross-linguistic phenomenon, reliably formed with a relativizer; a question subordinator; and X-marking. We thus present a compositional analysis of the constructions based on extant analyses of as (and its cross-linguistic counterparts) as a relativizer (Rett 2013, among others); if as a question subordinator (Starr 2014b, among others); and X-marking as encoding a similarity relation across possible worlds (Schulz 2014; von Fintel & Iatridou 2020). In addition to being compositional, this approach can better account for the wide distribution of ‘as if’ constructions both within a language and across languages.
Locality in the Derivation of Cumulativity
Authors: Harada Masashi
Published: February 2023

It has been proposed that the part structures of denotations of plurals ‘project’ to the denotations of expressions including those plurals (e.g., Gawron & Kehler 2004, Kubota & Levine 2016, Schmitt 2019/2020). If such a plural projection is possible, not only plural DPs but also expressions including those plural DPs denote pluralities (e.g., saw the two recipes denotes a plurality {SAW(recipe1),SAW(recipe2)} instead of a singularity {SAW({recipe1,recipe2})}). One piece of support for plural projection comes from Schmitt’s (2020) observation about ‘non-local’ cumulativity. In this paper, I further examine when cumulativity is available non-locally, and show that a source of cumulativity in the literature (e.g., Krifka 1989, Kratzer 2007, Harada 2022b) can capture all the relevant non-local cumulativity data without plural projection while an analysis with plural projection can capture only a proper subset of those data. Therefore, this paper concludes that the relevant non-local cumulativity does not support the need of plural projection.
Tradition, Nationalism and Holocaust Memory: Reassessing Antisemitism in Post-Communist Romania
Authors: Chelaru Valeria
Published: February 2023

This article is a re-evaluation of the Holocaust memory in the contemporary Romanian society. It shows that from its inception, Romania’s nation-building process went hand in hand with antisemitism. Furthermore, it points out that after 1989 the country’s sense of frustration at its communist past managed to obscure the memory of the Holocaust. Despite Romania’s government recognition of the country’s involvement in the Holocaust (2004), a wholehearted acknowledgement of the issue remains improbable at the general level of Romania’s society. A new law to counteract Holocaust denial was adopted in Romania in 2015. However, the country has proved ever since that it has barely come to terms with its historical legacy.*
The Orthodox Church and Education in Belarus as a Reflection of the Specific Pattern of Church-State Relations
Authors: Mudrov Sergei
Published: February 2023

This paper1
discusses the development of cooperation between the Orthodox Church and educational establishments in Belarus. The first Agreement on Cooperation between the Ministry of Education and the Belarusian Orthodox Church (BOC) was signed in 1994, several years before the adoption of a new Law on the Freedom of Conscience and the signing of the Agreement on Cooperation between the Church and the State. Although many objectives, stated in the first Agreement, were not met on time, there was a continuing and mutually beneficial cooperation between the Ministry and the BOC since
then, with a series of Programmes of Cooperation, signed every 2-4 years. The Orthodox Church is the only religious denomination in Belarus which concludes Programmes of Cooperation with the Ministry of Education; however, one cannot claim that the general legislative framework is particularly favourable for this Church. Indeed, there are some restrictions, limiting the presence of the BOC and its representatives in educational establishments. Also, the Church has not managed to get the inclusion of the “Foundations of Orthodox Culture” and related courses in the curriculum. At the same time, these courses can be taught as optional subjects, at the request of parents. In
addition, the BOC is able to organise various cooperation with educational establishments (seminars, lectures, regular talks, etc.); however, the scope and intensity of this cooperation largely depend on the will of the schools’ administration to interact with the Orthodox Church.

Employment legal relations in the IT sphere
Authors: Golosnichenko Dmytro
Published: February 2023

The article examines the features of the legal regulation of labor relations in the IT field. It is noted that the development of information and communication technologies is increasingly influencing the emergence of new forms of labor organization, and this requires changes in the legal regulation of labor relations between employee and employer. The notions of labor relations, which have been provided since the independence of Ukraine and the construction of a democratic, legal, social state with a market economy, are revealed. There is a scientific discussion on certain approaches in determining the characteristics of labor relations. It is emphasized that IT specialists often prefer to perform work and provide services in the status of natural persons — entrepreneurs on the basis of concluded civil law contracts for the provision of services or contracts. But at the same time there is a certain risk of reclassification of such relations from civil to labor with the corresponding legal consequences. The differences between the employment contract and civil law as possible options for legalizing the relationship to exercise the right to work in the field of IT are clarified. These in the study include: systematic performance of labor functions; until recently, subordination of the employee to the rules of internal regulations; remuneration at least twice a month with mandatory withholding of taxes and accrual of SDRs. The specifics of working in the IT field often include flexible working hours, remote or home work. This is also due to the fact that IT professionals, often, given the specifics of the activity, do not have a permanent job. Changes to the norms of the Labor Code on the regulation of relevant forms of labor organization are analyzed. The peculiarities of labor relations in the field of IT are also clarified by analyzing the specifics of the employment contract with a programmer, which is related to the intellectual property rights of the developed product, royalties and non-disclosure of confidential information.

Key words: labor relations, IT sphere, employment contract, civil law contract, flexible working hours, remote work, home work.

Owls have an incredibly unique ability to fly in silence, and this ability has significant potential to reduce noise pollution from aircraft engines. For decades, researchers have been studying the noise abatement system in conventional aircraft, but only a few of them had looked into the owl’s ability to reduce the aircraft noise level, especially on the serrated wing. The present study aims to investigate the lift and drag coefficient of the serrated wings including leading-edge serrations, trailing-edge serrations, both-edge serrations, and the original/baseline wing model from the NACA 0012 airfoil. The experimental testing was performed in a wind tunnel at Reynolds numbers of 20,000 and 40,000 and angle of attack from 2° to 30°, in 2° angle intervals. In general, the results showed that each wing model produced a similar lift and drag coefficient profiles, which were proportional to the angle of attack. At Reynolds number of 40,000, the lift coefficient increases from 0.45 to 1.5, as the angle of attack increases from 2° to 24°. Afterward, it decreased as the angle of attack exceeded 24°. According to the data, the trailing-edge serrations model showed the lowest drag coefficient at a Reynolds number of 40,000. Meanwhile, the highest lift coefficient at Reynolds number of 40,000 had been produced by the baseline wing model. This result is beneficial in reducing the noise generation produced by wing structure and at the same time enhancing aerodynamic efficiency.

Published: February 2023

In this study, the melting characteristics of hybrid nano-enhanced phase change material in a finned circular tube were studied by using the Finite volume method. This setup of circular tubes with a phase change material is used as cooling systems in automotive industries, air-conditioning, refrigerators, and other applications of cooling systems. There is a need for enhancing the specific heat capacity of this system to ensure that the system works even at high temperatures. As the current problem includes many design parameters and boundary constraints, the finite volume method has been performed to obtain a detailed report and data to examine the deformation of the hybrid nanoparticles and heat transfer rate on the corresponding surface. The current paper reviews and focuses mainly on the high-temperature PCM. And the suitable PCM has been selected based on its limitations and properties. To ensure the increased specific heat capacity, a salt-based phase change material, i.e., a mixture of NaNO3-KNO3 (60:40 ratio) binary salt. This PCM could hold a temperature up to 334◦C before melting to change its phase. In addition to spherical-shaped nanoparticles of silica (SiO2) in this binary salt, it tends to have a significant potential for enhancing the thermal storage characteristics of the NaNO3-KNO3 binary salt. On an extended surface, Finns are used on the peripheral of the circular tube to increase the surface area, which leads to an increase in frictional resistance resulting in a reduced airflow rate in the vicinity of the finned surface. From case studies, it has been found that the optimum fork-shaped fin array with two branches gives higher heat dissipation than the optimum rectangular fin. In the majority of the cases, the optimum fork-shaped fin array gives a 59.9% higher heat transfer rate compared to the rectangular fin array. Thus, the melting characteristics of the hybrid of NaNO3- KNO3 with nanoparticles of silica are studied when placed in a circular tube containing fork-shaped fins.
Determining the Right Nozzle Diameter Size and Their Effect on the Performance of Picohydro Technology
Authors: Eswanto  , Hanapi Hasan  , Nurdiana
Published: February 2023

New energy and renewable energy are solutions that can be applied to meet energy needs, especially those that are environmentally friendly. Currently, people, especially those living around energy sources such as rivers and irrigation, can independently create renewable power systems to produce energy. The application of picohydro power generation technology is the best solution in the application of environmentally friendly, independent, and renewable technologies. The purpose of this study was to determine the best performance of the nozzle output diameter of 3", 4", and 5" on picohydro technology using an Archimedes screw turbine. The research method was carried out by means of a prototype experiment using continuously circulated water fluid. The data collection process starts from the water discharge from the flowmeter, the rotation of the turbine blade, the rotation of the transmission, the rotation of the alternator, the pressure in the pressure gauge, and the power generated. The research results obtained information that at the smallest diameter (3") the nozzle pressure to the screw tip is not optimal because the water released by the nozzle only hits part of the screw leaf side, so that the performance is not optimal where the turbine shaft rotation at a maximum discharge of 30 m3/h is obtained at 230 rpm, while if the diameter of the output nozzle is given (5"), a lot of water is sprayed by the nozzle and it fills the screw leaves, which causes water to also overflow onto the screw in front of it, so that the flow does not normally flow from each screw, and it is also possible that the size of the input screw is not proportional to the output screw turbine, where the maximum rotation at a discharge of 30 m3/h is obtained at 247 rpm. For the size (4") it looks higher when viewed from the data obtained, this condition looks ideal in the size ratio between the input and output nozzles so that the resulting flow is also right to drive the turbine screw. The shaft rotation results obtained are 269 rpm for a water discharge of 30 m3/h.

R&D COLLABORATION BREADTH AND FAMILY-FIRM INNOVATION EFFICIENCY: THE ROLE OF FAMILY MANAGEMENT AND GENERATIONAL STAGE
Authors: Martínez-Alonso Rubén , Martínez-Romero María J. , Rojo-Ramírez Alfonso A.
Published: February 2023

This paper examines the relationship between R&D collaboration breadth and innovation efficiency within family firms. Based on the socioemotional wealth approach and recognising that family firms constitute a rather heterogeneous group, we study family firms’ differences in the way of addressing the R&D collaboration breadth-innovation efficiency link, taking into account family management and the generational stage. Using a panel dataset of 424 manufacturing family firms during the 2007–2016 period, we find significant differences across family firms in the translation of gains from R&D collaboration breadth into innovation efficiency. Specifically, our findings reveal that family firms with higher levels of family management and in first generational stage weaken the R&D collaboration breadth – innovation efficiency link.

P
=.02). Patients with anemia had a 16% higher risk of prolonged length of stay compared with patients without anemia (81% vs 65%,
P
=.009). In the linear regression model, preoperative hematocrit was associated with length of stay (
P
=.032) when adjusted for sex, age, preoperative tranexamic acid, preoperative hemoglobin, postoperative hemoglobin, and postoperative hematocrit. Length of stay was approximately 1 week in this study, with anemia being a statistically significant risk factor for prolonged length of stay. Health care providers and administrators can consider anemia on admission when predicting length of stay. [

Mentoring-as-Partnership: The Meaning of Mentoring Among Novice Nurse Faculty
Authors: Busby Katie Ruth , Draucker Claire Burke , Reising Deanna L.
Published: February 2023

Background:

Mentoring is recommended as a strategy to improve satisfaction and retention of novice nurse faculty to help address the current faculty shortage. However, the meaning of academic mentoring varies among faculty, which can detract from the development of effective mentoring relationships in academia. This article details the meaning of mentoring as characterized by novice nurse faculty.

Method:

Semistructured interviews were conducted with novice nurse faculty (
n
= 21) who participated in a mentoring relationship with experienced colleagues. Thematic analysis was used to identify themes detailing the meaning of mentoring as described by the participants.

Results:

The thematic analysis revealed an overarching theme of mentoring-as-partnership and three subthemes: (a) authentic communication, (b) enriching support, and (c) sharing knowledge.

Conclusion:

To strengthen mentoring relationships in academic nursing, focus should be placed on supporting mentoring partnerships marked by mutuality and clearly defined goals, roles, and responsibilities.

Use of Expert Modeling Videos in Undergraduate Nursing Education: A Systematic Review
Authors: Dodson Tracy M.
Published: February 2023

Background:

Novice graduate nurses are failing to demonstrate competent patient care in today's complex health care environment. Therefore, nurse educators have begun to critically explore educational methods, through the use of technology, that may affect student learning and clinical competency. Expert modeling videos is one strategy that allows students to observe expert behavior prior to practice and build exemplary care.

Method:

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for conducting a systematic review. Inclusion criteria for articles were: (1) experimental and nonexperimental, (2) peer reviewed, (3) primary research, (4), published in English, and (5) written through January 2021.

Results:

Fifteen studies were identified that met all of the inclusion criteria.

Conclusion:

Expert modeling videos have become an attractive educational strategy to promote learning in undergraduate nursing students. Future studies should focus on the use of these videos as a pedagogical strategy to transform learning in nursing education.

Teaching Professional Boundaries in Psychiatric Nursing: Resource Development
Authors: Thomson Andrea E. , Smith Nadine , Karpa Jane
Published: February 2023

Background:

A standard of practice in psychiatric nursing pertains to the ability to maintain professional boundaries within a nurse-patient relationship. Nursing students are inexperienced in maintaining nurse-patient relationships and are at risk of crossing professional boundaries. Research regarding boundary instruction and available resources is needed to guide educators.

Method:

Psychiatric nurse educators (
n
= 11) and psychiatric nurses (
n
= 9) were interviewed to determine what resources psychiatric nursing educators use to teach professional boundaries to undergraduate students. Following the interviews and preliminary analysis, eight participants also attended a focus group.

Results:

Participants reported resources such as textbooks were useful for defining professional boundaries. Participants also described case studies as a resource available to help operationalize boundaries in psychiatric nursing practice.

Conclusion:

Resources should be developed to address changes in care provision and technology to include cultural competence and guidelines for the use of social media.

Beam-Shaping Extended Depth of Focus Intraocular Lens: Optical Assessment With Corneas of Increasing Spherical Aberration
Authors: Madrid-Costa David , Fernández-Vega-Cueto Luis , Azor-Morón Juan A. , Vega Fidel , Millán María S. , Alfonso José F.
Published: February 2023

Purpose:

To assess the optical quality and halo formation of a beam-shaping extended depth-of-focus (EDOF) intraocular lens (IOL) (AcrySof IQ Vivity; Alcon Laboratories, Inc) with corneas of long-range spherical aberration (SA) such as those resulting from myopic laser ablations.

Methods:

The optical quality of the EDOF IOL and a reference monofocal IOL was evaluated with three corneas (A, B, and C, with SA =+0.135, +0.290, +0.540 µm, respectively, for a 5.15-mm pupil at the IOL plane). The through-focus modulation transfer function area (MTFa) curves were obtained between −5.00 and +2.00 diopters (D) defocus range. The halo was also assessed with the three corneas.

Results:

Through-focus MTFa curves for a 4.5-mm IOL pupil showed a slight decrease in the maximum MTFa value provided by the EDOF IOL compared to the monofocal IOL in the three corneal situations (A: 45.9 vs 38.6 units; B: 41.1 vs 33.1 units, and C: 26.9 vs 23.8 units). For the 3.0-mm pupil, the EDOF IOL also had lower maximum MTFa than the monofocal IOL; however, the depth-of-focus increased to −2.20 D. With corneas A and B, the halo induced was of low energy with both IOLs. With cornea C, the EDOF IOL created a much larger and intense halo.

Conclusions:

The EDOF IOL provided a good distance optical performance and an extended range of focus of approximately 2.00 D, with a halo of low intensity when evaluated with a corneal SA similar to the one induced by a low to moderate myopic ablation. With a high myopic ablation, the halo induced would be of considerable size and energy.

Take the Shot: A Review of Vitamin K Deficiency
Authors: Shaw Mariah A. , Liu Amy
Published: February 2023

Vitamin K is essential for the process of coagulation. In its absence, severe and sometimes fatal bleeding events can occur, especially in newborns. Vitamin K prophylaxis at birth has been shown to prevent morbidity and mortality associated with vitamin K deficiency bleeding (VKDB) and is recommended by multiple organizations including the American Academy of Pediatrics and the World Health Organization. Pediatricians should feel comfortable explaining the risks and benefits of vitamin K prophylaxis to families and should be equipped to recognize signs of VKDB, especially given increasing rates of parental refusal. This article aims to improve understanding of VKDB, including prevention, early recognition, and treatment.

Access to Pediatric Eye Care During a Pandemic: Systematic Review and Meta-Analysis
Authors: Kandiah Trisha , Li Xiaole , MacMillan Yannick , Malvankar-Mehta Monali S.
Published: February 2023

Visual impairment affects many children and can lead to blindness if untreated. The coronavirus disease 2019 (COVID-19) pandemic has led to various restrictions and other challenges accessing in-person medical care, including essential pediatric eye care. The aim of this article was to determine and quantify the effect that pandemics have on access to pediatric eye care. A systematic literature search was conducted using various databases, which yielded 257 articles; nine were included in the final review. All included studies reported a decrease in the number of children accessing eye care during COVID-19. Most studies described virtual triage systems, which restricted in-person care to emergent cases. The average decrease in daily pediatric visits was 67.32% and reached statistical significance in the meta-analysis (
P
< .01). However, out of all patients with ocular complaints, the proportion of pediatric visits was unchanged, suggesting that the decrease in access to eye care was not specific to pediatric patients.

Complications, Compliance, and 3-Year Outcomes After Endolaserless Vitrectomy With Aflibercept Monotherapy for Proliferative Diabetic Retinopathy-Related Vitreous Hemorrhage
Authors: Kasetty Venkatkrish M. , Starnes Davis C. , Sood Nitish , Qin Luke G. , Moses Mary M. , Frazier Heather K. , Singh Harinderjit , Marcus Dennis M.
Published: February 2023

Background and Objective:

To report the 3-year outcomes for endolaserless vitrectomy with intravitreal aflibercept injection (IAI) monotherapy for proliferative diabetic retinopathy (PDR)-related vitreous hemorrhage (VH).

Materials and Method:

Eyes underwent endolaserless vitrectomy and received one preoperative and intraoperative IAI followed by randomization to a q8week or q16week IAI group. Additional IAI was administered as needed.

Results:

31/40 eyes were randomized (14 q8week eyes, 17 q16week eyes). Through 152 weeks, q8week and q16week eyes received 18.6 and 12.1 IAI, respectively. Q8week eyes observed a 34 letter visual acuity (VA) increase (
P
= 0.003) compared to a 27 letter increase in the q16week group (
P
= 0.013).

Conclusions:

Endolaserless vitrectomy with aflibercept monotherapy for PDR-related VH provides significant long-term visual gains. Frequent IAI is required for fewer proliferative consequences.
