AbstractBackgroundA mindfulness‐based intervention that reduces comorbid pain, anxiety, and substance use during office‐based opioid treatment (OBOT) could enhance retention and prevent overdose. We conducted a pilot study of the Mindful Recovery OUD Care Continuum (M‐ROCC), a 24‐week trauma‐informed program with a motivationally‐sensitive curriculum.MethodsPatients prescribed buprenorphine (N = 18) enrolled in M‐ROCC. We collected urine toxicology biweekly. At 0, 4, and 24 weeks, participants completed PROMIS‐Pain, PROMIS‐Anxiety, Mindfulness (FFMQ), Experiential Avoidance (BEAQ), Interoceptive Awareness (MAIA), and Self‐Compassion (SCS‐SF) scales. We estimated changes over time using mixed models. Participants completed qualitative interviews at 4 and 24 weeks.ResultsPositive urine toxicology decreased over time for cocaine (β = −.266, p = .008) and benzodiazepines (β = −.208, p = .028). M‐ROCC reduced PROMIS‐Pain (Z = −2.29; p = .022), BEAQ (Z = −2.83; p = .0005), and increased FFMQ (Z = 3.51; p < .001), MAIA (Z = 3.40; p = .001), and SCS‐SF (Z = 2.29; p = .022). Participants with co‐morbid anxiety had decreased PROMIS‐Anxiety (Z = −2.53; p = .012). Interviewed participants commonly used mindfulness practices for stress and anxiety (12/12, 100%), and to reduce pain catastrophizing and rumination (7/12, 58%).Conclusion and Scientific SignificanceThis is the first study to report the effects of a 24‐week mindfulness program during buprenorphine treatment on common comorbidities, including pain interference, anxiety, cocaine, and benzodiazepine use. The findings that M‐ROCC is associated with reduced experiential avoidance, as well as increased interoceptive awareness and self‐compassion, align with proposed mechanisms that are now extended to OUD treatment. Future larger randomized controlled trials are needed before effectiveness can be established and the role of these mechanisms can be confirmed.

AbstractObjectivesIn patients with primary aldosteronism (PA), multiple adrenocortical nodules may be present on the surgical side. The aim of this study was to clarify the pathological diagnosis and the node‐by‐node diagnostic capability of segmental adrenal venous sampling (sAVS).DesignRetrospective study.PatientsA total of 162 patients who underwent adrenalectomy following sAVS were studied.MeasurementsMultiple nodules on the surgical side were extracted while referring to contrast‐enhanced computed tomography images. We also performed a detailed histopathological analysis of the resected specimens from patients undergoing sAVS, which included immunohistochemistry for CYP11B2.ResultsIn 11 (6.8%) patients, two to three nodules were detected on the surgical side. All patients were diagnosed by sAVS with at least one aldosterone‐producing adenoma (APA) for localized aldosterone elevation in tributaries. Seven patients showed a lateralization index value of ≥4 after ACTH stimulation. Histopathologically and clinically, two patients had two or three CYP11B2‐positive APAs, and the other nine patients both APAs and non‐APAs. The positive predictive value of the most suspected APA, that is, the drainer that showed the highest aldosterone level by sAVS, was 11/11 (100%, 95% confidence interval [CI]: 71.5%–100%), while that for the second and third suspected APA was 3/7 (42.9%, 95% CI: 9.9%–81.6%), and they were significantly different (p = .01). Further, the positive predictive value of non‐APA was 4/4 (100%, 95% CI: 39.8%–100%).ConclusionsThe sAVS could correctly diagnose the aldosterone production in multiple ipsilateral adrenal nodules.

Published: December 2022

AbstractThe Internet of Health Things (IoHT) has grown in importance for developing medical applications with the support of wireless communication systems. IoHT is integrated with many sensors to capture the patients' records and transmits them to hospital centres for analysis and reporting. Controlling and managing health records has been addressed in several ways, however, it is noted that two key research problems for vital communication systems are reliability and reducing data loss. To enhance the sustainability of health applications and effectively use the network infrastructure when transferring sensitive data, this research provides a machine learning approach. Moreover, data collected from the IoHTs are protected and can be securely received for physical process in hospitals using authentication trees. Firstly, the undirected graphs are explored based on the multi‐parametric machine learning approach to minimize the computation overheads and traffic congestion. Secondly, it evaluates the nodes' level behaviour over the heterogeneous traffic load with efficient identification of redundant links. Finally, in‐depth analysis and simulation results have shown that the proposed protocol is more effective than existing approaches for data accuracy and security analysis.

Published: December 2022

AbstractBACKGROUNDSuicide among adolescents has long been linked to symptoms of depression. However, limited research has examined the potential buffering effect of hope on the relationship between depression and suicide attempts.MethodsTo test the effect of hope on the positive relationship between depression and suicide attempts, we used data (N = 502 adolescents) from youth ages 12‐18 collected as part of the 2018 Healthy Youth Survey in the State of Washington. Based on hope theory, we hypothesized a “buffering” form of moderation, with the presence of greater hope weakening the positive relationship between depression and suicide attempts. In other words, with higher hope, adolescents reporting depressive symptoms are less inclined to attempt suicide.ResultsTesting the moderating effect of hope via bootstrap resampling (N = 5000), the results indicated adolescents' hope levels indeed buffered the relationship between depressive symptoms and self‐reported suicide attempts. To wit, when adolescents' hope was low, there was a significant, robust, and positive relationship between depressive symptoms and suicide attempts (b = 0.2644, 95% CI [0.1604, 0.3683], t = 5.0, p < .001). However, when adolescents' hope was high, there was no longer a significant relationship between depressive symptoms and suicide attempts (b = 0.0304, 95% CI [−0.997, 0.1605], t = 0.4590, p = .65).ConclusionThe buffering effect of hope was validated in a second, larger sample (n = 9308) of adolescents. This result suggests the potential utility of hope theory‐based interventions to assist depressed adolescents reduce their likelihood of suicide.
Gas-Turbine Power Plants for Operation With Low-Cost Fuel
Authors: Goldsbury John 
Published: December 2022

Abstract
This paper presents a discussion of the economics and general design requirements of gas-turbine power plants to be operated with low-cost fuel, such as natural gas and crude oil in the oil fields, refinery by-products, and by-product gases from industrial processes. It is pointed out that factors affecting first cost become relatively more important than those affecting efficiency as fuel cost decreases. When fuel cost is very low, water injection may well be considered if a suitable supply of water is available. Brief mention is made of the flow-type turbine power plant with preheated gas, which is a special case of the combustion-gas-turbine power plant. Approximate costs of these flow-type turbine power plants are given.
A Remote-Indicating Pressure Gage for Aircraft
Authors: Jewell R. G. 
Published: December 2022

Abstract
The indication of aircraft-engine oil and fuel pressures presents numerous problems. A brief study of existing gages shows that the two most serious problems are low temperature and engine vibration. A new gage has been developed to overcome these difficulties. The gage utilizes a second-harmonic remote-indicating system which is unique in that only one lead wire and ground return are required between indicator and transmitter.

Aerodynamic Heating and Convective Heat Transfer—Summary of Literature Survey
Authors: Johnson H. A. , Rubesin M. W. 
Published: December 2022

Abstract
The analytical and experimental information appearing in the literature for convective heat transfer at high velocities is summarized. Particular emphasis is given to heat transfer for submerged flow over flat plates, wedges, cones, and cylinders with a single reference to flow in pipes. The evidence presented supports, as a fundamental heat-transfer relation, the modified Newton’s law of cooling q=hA[tw−(to+ruo2/2gJcp)] where the term ruo2/2gJcp) accounts for the influence of frictional dissipation and is readily evaluated when the recovery factor r is known. A second and very important result is the evidence given to show that the heat-transfer coefficient h, is independent of the magnitude of the frictional-dissipation term. Data are presented for the recovery factor and heat-transfer coefficient for high-speed subsonic- and supersonic-flow velocities. It should be noted, however, that heat transfer by radiation is not considered here as it would be treated in the usual manner for heat transfer without frictional dissipation.
The Parallel Development of Heavy Self-Contained Hydraulic Presses in the United States and Great Britain
Authors: Towler F. H. 
Published: December 2022

Abstract
The object of this paper is to survey the parallel development of heavy self-contained hydraulic presses in the United States and Great Britain in the hope that an exchange of ideas may be helpful to future development in both countries. The self-contained press has been made possible by the development of a compact high-speed pump using oil as the hydraulic medium; and the construction of the pump has a considerable influence on the design of the press. In the United States the tendency has been to use pumps of the rotary-valve type operating at a maximum pressure of about 3000 psi, with a comparatively thick oil of around 300 Saybolt at 100 F. In Great Britain there is a growing tendency to use pumps of the seated-valve type capable of a working pressure of 7000 psi, and using a thin oil of 60 Saybolt at 100 F. The relative advantages and disadvantages are discussed.

Air Flow Through Small Orifices in the Viscous Region
Authors: Linden H. R. , Othmer D. F. 
Published: December 2022

Abstract
Experimental data for air flow through square-edged circular orifices and their correlation with the pressure difference, the orifice diameter, and the air temperature are presented in nomographic form. The correlation holds well for small orifices with diameters ranging from 1/16 to 3/16 in., for pressure differences from 0.015 to 0.500 in. of water, and negligible velocity of approach. The air-temperature range within which the correlation can be applied is from 70 to 300 F, and corrections for barometric pressures from 27 to 32 in. of mercury can be made. The main use of this correlation will be found in its application to oil-burner design. By inclusion of the carbon-hydrogen-ratio criterion, the nomographic representation may be integrated with the system of combustion calculations, based upon the carbon-hydrogen ratio developed by the authors (1). The nomograph enables the designer to calculate the theoretical fuel rate at which any hydrocarbon fuel can be burned per square inch of air-orifice area at a given pressure difference across orifices of known diameter and at specified air temperature, air pressure, and air humidity.
Reaction Tests of Turbine Nozzles for Subsonic Velocities
Authors: Kraft Hans 
Published: December 2022

Abstract
A large number of turbine nozzles were tested by means of measuring the jet reaction. The results permit a study of the effect of most of the variables which play a role in turbine design. The design of the flow elements of turbines whether they be considered as passages or as profiles always involves a number of compromises between conflicting characteristics. Effects due to changes in the form of the nozzle partitions, their angle, their spacing, their length (called radial height), and their exit-edge thickness are shown. The tests were made during the years 1920–1928. They are here presented for the record, together with some interpretation of their meaning in the light of modern aerodynamics.
Southwark Station Boiler Air-Flow Model Tests and Operation Results
Authors: Lane R. A. , Morrison E. L. 
Published: December 2022

Abstract
This paper discusses the engineering application of scale-model study of the combustion-air distribution for a proposed boiler installation. By obtaining an intimate mix of fuel and air, a more nearly uniform and nonreducing atmosphere results in the furnace to avoid the phenomenon of tube wastage. Following the operation of the prototype boilers, field tests were made for direct comparison with the model results. These comparisons, the actual combustion-gas analyses, and the boiler performance are reviewed.
Methods and Instrumentation for Furnace Heat-Absorption Studies: Temperature and Composition of Gases at Furnace Outlet
Authors: Cohen Paul , Corey R. C. , Myers J. W. 
Published: December 2022

Abstract
As part of the general program of investigations by the ASME Special Research Committee on Furnace Performance Factors, the Combustion Research Section of the Bureau of Mines is making a series of determinations of furnace heat absorption of representative pulverized-coal-fired boiler furnaces. During the course of these studies, modifications have been made in the test technique to improve the precision of furnace testing. Automatic recording instruments have been employed, which permit more detailed sampling and examination of furnace-outlet gases than heretofore, without an appreciable increase in the time or work required. Improved designs of radiation shields have been developed for high-velocity thermocouples with accuracy comparable to the B&W multiple-shield high-velocity thermocouple, but which may be employed conveniently in pulverized-coal-fired furnaces. Detailed descriptions are presented of the distribution of gas composition and temperature at the outlet of a 640,000-lb per hr horizontally fired boiler furnace. Based upon this knowledge, the sampling characteristics of the gases at the furnace outlet for furnace heat-absorption measurements have been examined, and a procedure is suggested for the rational selection of simplified sampling schedules. The methods of calculating furnace heat absorption from the temperature and gas-composition data are examined critically with special emphasis on the effect of weighting with respect to mass velocity. Suggestions are presented whereby the significance of mass velocity for furnace heat-absorption calculations may be determined from the temperature and gas-composition data.
Application of Steam-Jet Ejectors in the Houdry Fixed-Bed Catalytic Cracking Process
Authors: Freneau Philip , Kelso George , Hoge A. W. 
Published: December 2022

Abstract
During recent years many articles have appeared in technical publications describing the Houdry fixed-bed catalytic cracking process. Most of the papers have discussed in detail the excellent characteristics of the aviation fuels, motor gasolines, and other products that are produced by this process, but few have described the importance of, or the operation of, the auxiliary equipment which has contributed materially to its success. Since the engineering developments associated with the process have been almost as novel and interesting as the ground-work of petroleum catalysis, the purpose of this paper is to discuss the fundamental theoretical aspects and the operation of the steam-jet ejectors which have been instrumental in maintaining the satisfactory performance of Houdry fixed-bed units. To the engineer, the data presented herein should be of particular importance because ejector design is generally not clearly understood and because the application of ejectors in the Houdry process is unique. Part 1 of the paper deals with the process itself, the principles of ejector design and operation, and details of Houdry unit air evacuators. Part 2 is devoted to a study of the application of ejectors to two other services in the Houdry process, viz., the evacuation of oil vapors during oil-purge periods and the maintenance of vacuum on the closed circulatory heat-transfer salt systems.
Airplane Quieting I—Measurement of Sound Levels in Flight
Authors: Beranek L. L. , Rudmose H. Wayne 
Published: December 2022

Abstract
This paper covers the types and use of equipment for the measurement of noise in aircraft and outlines procedures of measurement which will yield data of maximum value to the acoustical design engineer. The use of a standard sound reference level, of root-mean-square indicating meters, and of “flat” response-measuring equipment is urged. The three principal types of noise meters are described and their relative advantages discussed. The specifications which the individual components of the noise-measuring equipment should meet are discussed in a general way and extensive references are given for a more detailed study. Data are given showing the averaging characteristics of seventeen commercially available audiofrequency indicating instruments. Finally, suggested procedures for analyzing noise in aircraft during flight are presented.
Terminal Velocity as the Measure of Dust-Particle Characteristics
Authors: Foley R. B. 
Published: December 2022

Abstract
Although the behavior of fine dusts in air or any other fluid and the ease with which they can be separated from an air stream, is often expressed in terms of particle diameters in microns, this relationship is based on Stokes’s law which assumes that the particles are spherical and of uniform density. Since most industrial dusts are a mixture of particles of irregular shapes and varying densities, this paper will show the importance of considering the effect of all particle characteristics, size, shape, and density, upon its behavior in a fluid. It will also show that the terminal velocity of a dust particle is a measurement of the combined effect of all three particle characteristics as they affect its behavior.
The Removal of Deposits From Steam-Turbine Steam Passages
Authors: Warren G. B. , Howard T. W. 
Published: December 2022

Abstract
Deposits in turbine steam passages, formed from the steam during operation, are reducing the efficiency and capacity of an appreciable portion of steam turbines in use in central stations today. In many power plants periodic cleaning is required to remove these deposits.
This paper is the result of an effort by a steam-turbine-manufacturer’s engineering group to collect existing operative practices of removing deposits from turbine steam passages; to subject these practices to the critical examination of the turbine designing engineers; and then to write a group of recommended procedures for such cleaning. It is not intended that the present paper with its recommendations is to be either complete or final, but rather that it will answer an immediate need, and serve as a starting point for discussion, criticism, and experimentation looking toward substantial improvement in the technique. Further, and perhaps more important, it is hoped that it will serve as an inspiration for the development of a much more needed technique, that of so designing boilers or of so operating power plants that turbine steam-passage deposits will not develop, because only by such prevention will complete economic loss from this difficulty be eliminated.
The Shock Produced by a Collapsing Cavity in Water
Authors: Osborne M. F. M. 
Published: December 2022

Abstract
It is shown that cavitation shocks are recurrent or multiple, the time interval separating them depending primarily on the size of the cavity. Further, it is shown that the abruptness and violence of the shock, the total acoustic energy produced and its frequency distribution are all highly dependent on the size of the residual air bubble around which the cavity collapses. The size of this bubble determines the degree of cushioning of the shock; hence the undesirable characteristics of the shock, as measured by noise production and mechanical destruction, are much diminished as the air-bubble size increases, and the predominant frequency of the noise generated shifts to the lower frequencies. Quantitative relationships for these variables have been obtained as a function of cavity size (or energy content of the blow) and air-bubble size. These are the two significant variables, the properties of the shock are insensitive to the shape of the cavity and the material against which collapse takes place.
