Authors: Schuler Christina , Waldboth Veronika , Ntow George Edward , Agbozo Faith 
Published: February 2023

AbstractAimsTo explore the experiences of health professionals and families concerning supporting low‐birth weight (LBW) infants along the continuum of care (CoC) in Ghana with the goal to unveil new strategies to improve the quality of neonatal care.DesignA constructivist grounded theory.MethodSimultaneous data collection and analysis among health professionals alongside families with LBW infants from September 2020 to April 2021. The study used constructivist grounded theory strategies for data collection and analysis.ResultsThe analysis of 25 interviews resulted in a theoretical model describing 10 themes along the CoC for LBW infants, categorized into health and family systems drivers. In this paper, we focus on the latter. Early bonding and family involvement were empowering. Mothers needed assistance in balancing hope and confidence which enabled them to render special care to their LBW infants. Providing mothers with financial and domestic support as well as creating awareness on newborn health in communities were important.ConclusionTo achieve family involvement, a coordinated CoC must entail key players and be culturally inclusive. It must be applied at all levels in the CoC process in a non‐linear faction. This can help LBW infants to thrive and to reach their full developmental potential.ImpactThe theoretical model developed shows the importance of family involvement through family systems care for a comprehensive response in addressing needs of health professionals and families with LBW infants and bridging the fragmentations in the neonatal CoC in Ghana. Context‐tailored research on family systems care in the neonatal period is necessary to achieve a quality CoC for LBW infants and their families.Patient or Public ContributionCaregivers and providers participated by granting in‐depth interviews. Care providers further contributed through their feedback on preliminary findings.
Flooding time nomograph for urban river flood prediction: Case study of Dorim stream basin, Seoul

AbstractGlobal climate change is intensifying flood damage in urban rivers. Notably, most small and medium‐sized urban rivers have a brief concentration period and are highly vulnerable to sudden heavy rains that lead to a rapid increase in water levels. Therefore, rapid flood forecasting must be performed through accurate flood occurrence and timing prediction. In this study, a flooding time nomograph (FTN) was proposed to predict the flood occurrence time according to rainfall conditions, such as intensity, time distribution, and duration. In addition, rainfall–runoff simulations were performed by establishing different virtual rainfall scenarios using Huff's quartile rainfall time distribution. The simulation results were used to formulate the relationship between the rainfall intensity and flood occurrence time to generate the FTN. The applicability of this tool was verified through a comparison with the observed flood occurrence time for an actual rainfall event, which was highly accurate in the target watershed, with a correlation coefficient >0.8 and Nash–Sutcliffe efficiency >0.6. Therefore, the proposed FTN can be used to reasonably predict the occurrence of floods and the time of flood occurrence using only predicted rainfall information.

Published: February 2023

AbstractAimsThis study aims to develop and examine the effectiveness of a support program for reducing moral distress of nurses, based on the moral case deliberation methodology, and to study the feasibility of its implementation.MethodsStudy design was an intervention study with pre/post‐comparison. The support program included a short lecture and three moral case deliberation sessions for nurses working in an acute care hospital. The Measure of Moral Distress for Healthcare Professionals (MMD‐HP) and the Euro‐MCD (Moral Case Deliberation) 2.0 scale were used for pre/post‐comparison, using the Wilcoxon's signed‐rank test. Furthermore, post‐intervention interviews were conducted with consenting participants to determine the reasons for changes in pre/post‐intervention quantitative data. Of the 34 participants, 29 completed the post‐questionnaire and were included in the quantitative data analysis, and 27 were included in the qualitative data analysis.ResultsThe mean MMD‐HP total scores increased from 147.5 ± 61.0 to 159.3 ± 66.7, but not significantly (p = .375). The mean score of moral competence, a sub‐scale of the Euro‐MCD 2.0, increased significantly from 15.4 ± 2.4 to 16.4 ± 2.8 after the intervention (p = .036). A qualitative analysis revealed increased moral sensitivity to ethically difficult situations and improved analytical skills as the reasons for change in scores pre/post‐intervention.ConclusionThe results of the qualitative analysis suggested the effectiveness of the intervention. The moral distress score increased, although not significantly, and moral competence also increased, suggesting the participants' values changed after the intervention. It was found that the support program using MCD is expected to improve participants' moral competence.

AbstractBackgroundIn recent years, platelet‐rich plasma (PRP) has been used in plastic surgery, dermatology, and other treatment procedures worldwide. Since the number of scientific writings has been significantly increasing, it is challenging to generate a manual compilation and systematic review of PRP's therapeutic applications in dermatology and plastic surgeries. This study aimed to make a bibliometric analysis of the literature in the field and evaluate research hotspots and frontiers in this field in the past 20 years.MethodsUsing the Academic Search Premier and ScienceDirect defined search terms, we searched the Web of Science Core Collection (WoSCC) and Scopus databases. All data were analyzed using CiteSpace 5.8.R3 and VOSviewer, including countries, institutions, authors, keywords, cited authors, cited journals, cited references, discovered research hotspots, and frontiers.ResultsA total of 1931 studies were retrieved. The number of publications on PRP application in dermatology and plastic surgeries showed a yearly increase. The United States was the most significant contributor to this field, while Italy's contribution was noteworthy. The journal with the highest number of relevant articles in dermatology and plastic surgery included the Journal of Cosmetic Dermatology. However, the Wound Repair and Regeneration and International Journal of Molecular Sciences were the leading journals that should be paid attention to in the future. Author Anitua E from the Tor Vergata University of Rome published the most publications in this field. In the keyword co‐occurrence analysis, all keywords were divided into six clusters, and the most common one in recent years was “PRP for facial beauty.” Facial rejuvenation, scar, and alopecia were the main hotspots and research trends in this field.ConclusionsBased on the current global trends, the use of PRP in cosmetics and skin care is receiving increasing attention from researchers and clinicians. Recently, an increasing number of articles on PRP's application in skin tissue repair have been published in the United States and Italy. The number of studies on hair loss, facial rejuvenation, and scar management is increasing, suggesting that these subjects may become research hotspots for PRP in dermatology and cosmetic surgeries in recent years.
Current status and molecular biology of human papillomavirus‐independent gastric‐type adenocarcinoma of the cervix
Authors: Nishio Shin 
Published: February 2023

AbstractThis article reviews the findings of clinical studies on gastric‐type adenocarcinoma of the cervix to date, outline the molecular biological features identified in recent studies, and discusses the future therapeutic strategies. Gastric‐type adenocarcinoma of the cervix is a new classification in the World Health Organization 2014 classification. The World Health Organization 2020 classification further divides cervical tumors into two categories: human papillomavirus‐associated and human papillomavirus‐independent. Thus, gastric‐type adenocarcinoma of the cervix is now classified as a human papillomavirus‐independent gastric type. Clinical studies have reported that gastric adenocarcinoma of the cervix is refractory to conventional chemotherapy and radiotherapy, and it is desirable to elucidate its molecular biological mechanism. A series of gene mutations characteristic to the gastric‐type adenocarcinoma of the cervix encourage the development of future treatment strategies.

AbstractChemical signal‐mediated biological communication is common within bacteria and between bacteria and their hosts. Many plant‐associated bacteria respond to unknown plant compounds to regulate bacterial gene expression. However, the nature of the plant compounds that mediate such interkingdom communication and the underlying mechanisms remain poorly characterized. Xanthomonas campestris pv. campestris (Xcc) causes black rot disease on brassica vegetables. Xcc contains an orphan LuxR regulator (XccR) which senses a plant signal that was validated to be glucose by HPLC‐MS. The glucose concentration increases in apoplast fluid after Xcc infection, which is caused by the enhanced activity of plant sugar transporters translocating sugar and cell‐wall invertases releasing glucose from sucrose. XccR recruits glucose, but not fructose, sucrose, glucose 6‐phosphate, and UDP‐glucose, to activate pip expression. Deletion of the bacterial glucose transporter gene sglT impaired pathogen virulence and pip expression. Structural prediction showed that the N‐terminal domain of XccR forms an alternative pocket neighbouring the AHL‐binding pocket for glucose docking. Substitution of three residues affecting structural stability abolished the ability of XccR to bind to the luxXc box in the pip promoter. Several other XccR homologues from plant‐associated bacteria can also form stable complexes with glucose, indicating that glucose may function as a common signal molecule for pathogen–plant interactions. The conservation of a glucose/XccR/pip‐like system in plant‐associated bacteria suggests that some phytopathogens have evolved the ability to utilize host compounds as virulence signals, indicating that LuxRs mediate an interkingdom signalling circuit.
Studies in Photoelastic Stress Determination
Authors: Weibel E. E. 
Published: February 2023

Abstract
This paper covers three laboratory studies in photoelastic stress determination.
The first of these is an investigation of the strain-creep characteristics of bakelite and phenolite. It was undertaken in the belief that the information to be obtained would indicate how closely the behavior of these materials under load approached the theoretical proportionality of strain to stress; the significance of exact knowledge of the degree to which this relationship holds true being that the deduction of stress distribution in structural materials by photoelastic means is based on the assumption that the photoelastic specimen does conform to Hooke’s law. The tests performed are described in detail and from the results it is concluded that with these materials the departure from the Hooke’s law stress-strain relationship is exceedingly small and does not vary with time of loading within a two-hour period.
The second study was undertaken in the belief that more accurate information regarding stress concentration at points of sharp change in sections of machine parts could be obtained with bakelite and phenolite and the monochromatic fringe-photograph method than obtained previously with celluloid models. The paper describes the methods used in testing for both tension and bending and includes fringe photographs illustrating the changes in stress distribution for different ratios of fillet radius to the width of the narrow section of the specimen. From these tests the author has established the values of the stress concentration factor, in both tension and bending, for a considerable range of the fillet-width ratio.
The third study as set forth in this paper is the application of the membrane analogy in conjunction with the photoelastic results to the determination of stresses in a specimen subjected to bending. A soap film, used as the membrane, was enclosed by a frame of same shape as the specimen being studied. Its boundary ordinates, measured perpendicularly, were made proportional to the corresponding boundary values of the sum of the principal stresses. Under these conditions the ordinates of all points of the membrane are proportional to the sum of the two principal stresses at the corresponding points on the stressed member. The lengths of the ordinates were measured by means of a depth michrometer and the stress values at the corresponding points on the stressed member determined from these. Because of the ease of application and accuracy of the results obtained it is believed that the membrane analogy will find increasing use in conjunction with photoelastic studies.
The V-Notch Weir for Hot Water
Authors: Smith Ed S. 
Published: February 2023

Abstract
This ideally simple form of weir has a wide, accurate range for heads up to about one foot, is inherently free from aeration difficulties, and has a better agreement between data from various sources than would be expected from experience with other weir forms generally. The present paper has to do strictly with weirs of the V-notch form, only, and their viscosity corrections with hot water, although the same method may also find some use with more viscous liquids, such as oils.

Authors: Windenburg Dwight F. , Trilling Charles 
Published: February 2023

Abstract
This paper discusses the collapse by instability of thin-walled cylindrical vessels subjected to external pressure. The most important of the theoretical and empirical formulas that apply to this subject are presented in a common notation. A new and simple instability formula is developed.
Three classes of tubes are considered: Tubes of infinite length; tubes of finite length with uniform radial pressure only; and tubes of finite length with both uniform radial and axial pressure. Collapsing pressures calculated by the various formulas are presented in tabular form as a means of comparing the formulas.
The formulas are discussed briefly and checked against the results of tests conducted at the U. S. Experimental Model Basin for the Bureau of Construction and Repair, Navy Department.
This paper is a sequel to one previously published as a part of the work of the A.S.M.E. Special Research Committee on the Strength of Vessels Under External Pressure.
The Correlation of Spring-Wire Bending and Torsion Fatigue Tests
Authors: Weibel E. E. 
Published: February 2023

Abstract
The investigation reported in this paper was an attempt to correlate bending and torsion fatigue results for tempered Swedish valve-spring wire so that the torsion fatigue strength might be inferred within reasonable limits of accuracy from the fatigue values found in the simpler rotating-beam test. The original program called for (a) the development of suitable methods of gripping the wire for the torsion fatigue tests; (b) the determination of bending and torsion fatigue values for one size of wire in the as-received condition, and also after removal of the surface layer in a centerless grinder; (c) the determination of fatigue values for other sizes of wire between ⅛ in. and ¼ as permitted by time limitations; and (d) a survey of the literature for data bearing on the correlation of bending and torsion results. The results of these experiments on straight specimens of tempered Swedish wire in torsion and bending fatigue may be summarized as follows:
1 Methods of gripping were developed which are satisfactory for both bending and torsion fatigue tests with the exception of torsion tests on shot-blasted wire.
2 Zero to maximum torsion fatigue values for straight specimens in the as-received condition were about 70 per cent higher than values estimated from previous tests on carefully coiled springs.
3 The smaller of two sizes of wire tested in the as-received condition had the higher torsion fatigue limit and lower ultimate torsional strength.
4 Removal of the natural surface by grinding increased the bending fatigue strength about 20 per cent, but decreased the torsion fatigue strength about 4 per cent.
5 Shot-blasting increased the bending fatigue strength about 27 per cent and increased the torsion fatigue strength an undetermined amount.
6 The zero-to-maximum torsion fatigue limits of two sizes of wire tested in the as-received condition were 1.5 and 1.6 times their respective bending fatigue limits.
7 For two sizes of wire in the as-received condition the values of 0.84 and 0.90 were obtained for the ratio of reversed torsion fatigue strength to reversed bending fatigue strength.
8 Approximate measurements of surface residual stress were made on the wire in different conditions before and after fatigue testing and before and after coiling, which may have a bearing on the fatigue properties of springs.
The Contributions of the U. S. Bureau of Mines to Helium Production
Authors: Seibel C. W. 
Published: February 2023

Abstract
The production of helium for commercial use is of particular interest at this time since it had its inception in the State of Texas and has been carried on chiefly in that state ever since. The development of helium production is an excellent example of how American engineers attempt the seemingly impossible—and win. It also demonstrates the rapidity with which an almost hopeless undertaking can be completed when a determination really has been made to do so and the necessary funds are available. In this paper are outlined the early history of helium production, the steps in the necessary preliminary research, and how the data were applied. Early repurification plants are described, and facts given concerning the present Amarillo plant.

Abstract
This paper describes the technique of determining the complete operating characteristics of a hydraulic machine such as a centrifugal pump or a turbine, together with a method of presenting these characteristics in a convenient manner on a single diagram. The characteristics of a modern, high-head, high-efficiency pump are analyzed and presented in the manner proposed. The use of these complete characteristics for the prediction of the behavior of the machine during operating transients is discussed and the analytical background is presented. The assumptions involved are investigated and experimental checks of their validity are offered. The interrelationships between the hydraulic characteristics of the machine and the pipe line are indicated.
Carbonaceous Zeolites—An Advance in Boiler-Feedwater Conditioning
Authors: Tiger Howard L. 
Published: February 2023

Abstract
The increased number of modern high-pressure steam boilers emphasizes the need for high-quality feedwater make-up of minimum scale-forming and minimum total-solids content consistent with the desired sulphate-carbonate ratio. The usual sodium zeolites hitherto known, which exchange their sodium base for calcium and magnesium (hardness), reduce this hardness to a minimum, but do not reduce total solids or alkalinity. The new hydrogen zeolites described in this paper retain the simplicity and complete hardness-removal characteristics of zeolite softeners and at the same time eliminate the alkalinity with (a) a corresponding reduction in total solids and CO2 content of steam, and (b) an increase in the sulphate-carbonate ratio. Furthermore, they remove alkalinity present in any form; thus, for the first time in history it is possible, by simple economical means, to remove sodium alkalinity often found in raw waters.
When the capacity of these hydrogen zeolites is exhausted, they are regenerated by dilute acid solutions in the same manner as a salt solution is used to regenerate sodium-zeolite softeners. By combining the hydrogen- and sodium-zeolite effluents in correct proportions, or by alkali neutralization, it is a simple matter to obtain a feedwater completely free from hardness and of any predetermined desired alkalinity.
These hydrogen zeolites are made of carbonaceous substances and are therefore practically free from silica. They can also be regenerated with common salt, and with such regeneration they can function in the usual sodium-zeolite cycle. Being extremely resistant to low pH waters and practically free from silica, and of relatively high capacity, they also possess great advantages when used in the usual sodium-zeolite cycle, especially where it is desired to avoid any increase in silica content, a condition that is gaining favor rapidly in the high-pressure-boiler feedwater field.
Quantitative Analysis of Single-Capacity Processes
Authors: Spitzglass Albert F. 
Published: February 2023

Abstract
The paper compares methods of quantitative analysis of continuous-process regulation. It complements the paper by C. E. Mason (17) by comparing the quantitative approach proposed by him with that of other writers, both American and foreign.
The fundamental considerations underlying process analysis and the simplifying assumptions necessary to facilitate mathematical approach are investigated. The equations of the regulator are defined and then combined with those for the process. The results are presented in tabulated form to permit making a critical analysis.
Only single-capacity processes are considered in this paper, and the consideration of multiple-capacity processes as well as the critical analysis is reserved for a later time.
