Long-Term Performance of Semimetallic Gaskets

Abstract Flexible graphite-based gaskets are used extensively in high-temperature applications as a replacement for asbestos-based gaskets. The effects of aging and temperature exposure on flexible graphite sheet gaskets were the subject of a previous work (Derenne et al., 1997, “Elevated Temperature Characterization of Flexible Graphite Sheet Materials for Bolted Flanged Joints,” Welding Research Council Bulletin, Issue 419, pp. 1–87.). In this paper, the effects of aging on flexible graphite under a confined-gasket configuration will be examined as they are yet unknown. This study outlines the performance evaluation of the elevated temperature behavior of flexible graphite-based gaskets under a confined configuration and long-term exposure employing a high-temperature aged leakage relaxation (HALR) fixture. This aged relaxation leakage adhesion test (ARLA)-like fixture retains the mechanical features of the aged tensile relaxation screening (ATRS)/high-temperature aged tensile relaxation (HATR) while enabling cold leakage rate and weight loss measurements. Four distinct semimetallic gaskets with different graphite-confined configurations, namely, corrugated metal, spiral wound, kammprofile, and double jacketed, were evaluated within a temperature range of 800–1200 °F (430–650 °C) for an exposure time of 2500 h. Graphite weight loss, gasket thickness change, leakage and tightness parameters, and creep and relaxation measurements were taken at regular intervals for each gasket style. To better assess the aging process, these critical mechanical and leakage properties were scrutinized; the influence of the degradation process, related mainly to graphite oxidation, was emphasized.

Emergence and Evolution of the Journal of Bangladesh College of Physicians and Surgeons: Igniting the Professionalism

Journal of Bangladesh College of Physicians and Surgeons (JBCPS), all the go by ‘BCPS Journal’, is the official organ of BCPS inclusive of academic, extra-academic and official matters. The journal started its journey in August 1983, now in the fourth decades is embedded in the fanfare of Golden Jubilee of BCPS. It commensurate with the fellows’ desire that a supplement of the JBCPS shall be published as the official organ of the college on behalf of the education, training, research and publication to Showcase the college image in the academic arena. The special editorial board is tasked to marinate a document of the sojourn of the JBCPS, for now and then. The authors have tried to pick up pieces of information from all available local libraries and online resources to build up an edifice to be added on from time to time. It has been tried to fullfill the mandate through expanded and extended search and find the tenets of the emergence and evolution of the JBCPS with an endeavor to bring out a canvas of the paintings of the stories of the Odyssey. Bangladesh Medical Journal (BMJ) published by Bangladesh Medical Association (BMA) is the oldest journal of the country first published 50 years ago in July 1972. Then the Bangladesh Medical Research Council Bulletin (BMRC Bulletin), published in December 1975. JBCPS is the third in this sequence. Prof Golam Rasul was the first editor in chief and so far, fifteen chiefs navigated the journal so far. The first editorial board consisted of five members and present editorial board embracing almost all the subjects including editors from abroad. JBCPS is online since 2004 and is available in the Bangladesh Journals Online (BanglaJOL) since 2006. With Continued relentless untiring efforts of the editorial board and collaboration from the executive committee of BCPS the JBCPS is now one of the top ranked & prestigious peer reviewed journal of the country. The next endeavor shall be to enlist the journal in PubMed which is expected very soon. J Bangladesh Coll Phys Surg 2022; 40: 28-38

THEME IN INDONESIAN – ENGLISH TRANSLATION TEXT

<p>This research is based on Linguistics Systemic Functional (LSF) and it observes the fronting idea and modeling in translation. Fronting idea can be seen from the Theme and the shift of Theme in a text ant its translation. This Theme and Rheme system is as part of LSF theory, whilst the ways or systems of translation are seen from Larson’s and Catford’s theories. There are sixteen different texts taken as data analyzed in this research from five different sources. They are from (1) The British Council Bulletin, (2) Political Speech; (3) Connexions Magazine; (4) Pelangi Magazine; (5) Islamic Speech Book. Each of the text is identified based on its Thematization including Marked and Unmarked Theme, Simple and Complex Theme, Singular and Plural Themes especially the Theme-Shift. From this analysis,, it can be also known the factors that cause the shifts of the Theme. The results of the analysis are: first, Plural Topical Marked Theme is the dominant Theme in both languages. Secondly, there are seven types of Theme shift in both languages, i.e. (1) the shift in simple Theme becomes complex or vice versa, (2) the shift in singular Theme becomes plural or vice versa, (3) the shift in marked Theme becomes unmarked ones or vice versa, (4) the shift in Theme position, (5) additional Theme, (6) omission, and (7) changing Theme. Thirdly, the factors that influence the Theme shifts in translation are caused by shifts of language units from Theme or Rheme or vice versa. Besides, it is also found that the additional of language units from English to Indonesian or vice versa, such as conjunctions, circumstance of place, manner, and time. On the contrary, it can also be caused by the existence of omission of language unit from English to Indonesian or vice versa. The shifts, additions, and omissions of language units cause and influence the forms, types, and the number of Themes from Singular Theme becomes plural ones and vice versa, and from Simple Theme becomes the complex ones or vice versa.</p>

NUMERICAL METHODS RESEARCH AND FRACTURE FAILURE ANALYSIS FOR CRITICAL CRACK SIZE

Safety analysis of fracture mechanics is an important part of structural integrity assessment and critical crack size is one ofmain concerns for fracture failure. From the perspective of mathematics, the calculation of critical crack size is the solving and analysis for nonlinear equation f(x)=0. About the solution of nonlinear equation, there are the bisection method, the false position method, the simple iteration method, the newton method and the secant method. For the complexity of load imposed on nuclear power equipment, there may be the multi-value phenomenon of critical crack size in analyzing fracture failure problems. Considering that the corresponding mechanical states of the shallow crack and the deep crack are different when the fracture failure occurs, the crack toughness factor needs to be considered in the fracture failure analysis of shallow cracks. Connecting the bottom head of nuclear power plant main equipment, the pipeline large break transient of accident condition and the welding research council bulletin 175, the algorithm and the convergence of multi-value phenomenon of critical size are studied. Using the crack toughness factor, the fracture failure critical crack size is deeply analyzed and discussed. The algorithm and fracture failure theory in the present study can provide the technical support for the prolonging operation life projects of nuclear power plant main equipment in future.

A Synoptic Review of the 1932 National Research Council Bulletin, “Possibilities and Need for Development of Legal Medicine in the United States”

In 1932, the National Research Council (NRC) published a Bulletin titled “Possibilities and Need for Development of Legal Medicine in the United States.” This article is a synopsis of the major points made in the 1932 Bulletin. The 135-page Bulletin was prepared for the National Research Council Committee on Medicolegal Problems by Oscar T Schultz MD, who was the Director of Laboratories at St. Francis Hospital in Evanston, Illinois. Chapters cover “Medical Science and the Law,” the “Need for the Organization of Institutes of Legal Medicine in the United States,” “Suggested Organization of an Institute of Legal Medicine,” “The State University and Legal Medicine,” “The Present and Future Development of Legal Medicine in the United States,” “Science and the Prevention of Crime,” “The Outlook for the Future,” a “Summary,” and three ancillary chapters. It was envisioned that institutes of legal medicine could parallel those in Europe and would be university affiliated, active and not theoretical, produce publications, and have renowned leaders and laboratory services such as bacteriology, immunology, chemistry, toxicology, and microscopy. They would also provide services on living people who were injured, and would do psychiatric assessments and evaluate witnesses and suspects. In short, the institutes would have services that met the needs of the criminal justice system. Eighty-two years following publication of the 1932 Bulletin, the institutes of legal medicine envisioned in the Bulletin have not come to fruition. Several institutes emerged since 1932 but have failed or are no longer formal institutes with multidisciplinary participants.

A Synopsis of the 1928 National Research Council's Bulletin on “The Coroner and the Medical Examiner”

The 1928 National Research Council (NRC) Bulletin on “ The Coroner and the Medical Examiner” is an often-referenced report because it compares the two system types and recommends that coroner systems be abolished and replaced with medical examiner systems. Copies of the Bulletin are difficult to find, so this article provides a synopsis of the Bulletin's content. The NRC Bulletin 64 was prepared under the auspices of the seven-member “Committee on Medicolegal Problems.” The report itself begins with a historical summary of the coroner system and discussion of the medical and judicial duties of coroners, along with the inadequacy of existing autopsy facilities. Next is a review of previous surveys of coroner systems in New York City, Cleveland, and Missouri. The Committee conducted its own surveys of the coroner systems in New Orleans, San Francisco, and Chicago. The Committee also studied the medical examiner systems in Boston, other parts of Massachusetts, and in New York City. Other sections deal with the comparative costs of the two systems, teaching of forensic medicine, medicolegal institutes, scientific publications, a summary of defects of coroner systems and advantages of medical examiner systems, and eight summary recommendations. We must remember that the historical Bulletin was written nearly a century ago, and there has been much improvement in medicolegal death investigation since that time, many improvements having their roots in the NRC Bulletin recommendations. The Bulletin's recommendations have been fulfilled to various extents in many parts of the United States.

"Organized Catholic Womanhood": Suffrage, Citizenship and the National Council of Catholic Women

“Organized Catholic Womanhood”: Suffrage, Citizenship and the National Council of Catholic Women* Jeanne Petit I n 1921, the laywomen of the newly-formed National Council of Catholic Women (NCCW) found themselves on the defensive. The National Catholic Welfare Council Bulletin had reprinted a speech by Archbishop Sebastian G. Messmer of Milwaukee, in which he minimized their work by declaring, “Man is made by God to fight the public battles, not the woman.”1 The NCCW, however, did not take this sitting down. An article in the Bulletin’s next issue, titled “Organized Catholic Womanhood,” did not mention Messmer’s name but did challenge the central premise of his speech by claiming that it was essential that Catholic women take the lead in public debates. Pointing to the changes caused by the Nineteenth Amendment, the anonymous author insisted that Catholic women needed to organize on a national level in order to counteract Protestant and secular women in national debates dealing with “not only the industrial but the moral well-being of woman.” Those who belittled or deemphasized the need for such an organization would achieve that “which the bigot and the anti-clerical so much desire—Catholic women as a united body are pushed into the background submerged in some secular so-called patriotic movement—divided among themselves.” “But,” the article continued, “the vision and wisdom of Catholic women will save us from that day . . . for we live our faith when we realize that we are all parts of the Body of Christ—The Church.”2 83 *This paper was presented at the 2007 National Endowment for the Humanities Summer Seminar on “Religious Diversity and the Common Good,” directed by Dr. Alan Wolfe of the Boisi Center at Boston College. Members of the seminar provided many helpful suggestions for improving this essay. The author would also like to thank Anita Specht, Janis Gibbs, Natalie Dykstra and John Hanson for their careful read and useful comments on this essay. 1. “Archbishop (S.G.) Messmer’s Forceful Appeal for the Men’s Council: Catholic Clergy Urged to Support Movement in Milwaukee Archdiocese,” The National Catholic Welfare Council Bulletin (June 1921): 23-24. In this speech, Messmer was promoting the newly-formed National Council of Catholic Men. 2. “Organized Catholic Womanhood,” NCWC Bulletin (July 1921): 16. Catholic women, according to the author, had to exercise their rights as citizens in order to defend and live their faith. A year later, the women of the NCCW again found themselves on the defensive, this time when their president, Gertrude Gavin, attended the 1922 Pan-American Women’s Conference in Baltimore sponsored by the League of Women Voters. Gavin left outraged after one of the speakers, Carrie Chapman Catt, had implied that Catholics were ardent opponents of suffrage for women, and another, Lady Astor, referred to the United States as a Protestant country. The NCCW’s executive committee quickly adopted resolutions stating that they deplored “the injection into the deliberations of the League of Women Voters statements concerning the attitude of Catholics toward suffrage which tend to sow dissention and misunderstanding among the members of the League, many of whom are Catholic women.” The resolution also attacked statements “concerning America being a Protestant country, statements out of harmony with historic truth, including the Constitution of the United States, which guarantees freedom of religious belief to all.”3 So again, the women of the NCCW took action when their citizenship status was denigrated, this time by defending their right as Catholics to be respected as equals within national women’s organizations. Since the early nineteenth century, Catholic women had built orphanages, hospitals and schools and performed other forms of what became known as social work, but sisters in religious orders, not laywomen, did most of this work.4 Moreover, most Americans, both Catholic and non-Catholic, did not see this work as political. The women of the NCCW saw themselves as doing something different. In creating a national, political organization for laywomen, they sought to define a civic identity for middle-class Catholic women, one where they would be full participants in the nation’s political process. As the stories above illustrate, however, the Catholic laywomen of the...

Three-Dimensional Stress Criteria—Summary of the PVRC Project

This paper summarizes work done by the Pressure Vessel Research Council (PVRC) on three-dimensional stress criteria, using primarily elastic two and three-dimensional analytical techniques, finite element analysis. The focus of the work was to recommend guidelines on evaluation of elastic stresses relative to the ASME Boiler and Pressure Vessel Code (Code) defined failure modes as they relate to stress limits. The guidelines are developed such that they may be used to update and expand the procedures for evaluating the required stress limits in Code Section VIII, Division 2 and Code Section III, Subsection NB. This paper summarizes the recommendation using ten guidelines. The project addresses eleven example problems, nine of which include finite element analyses. These example problems validate the recommendations. The detailed information is published in the Welding Research Council Bulletin 429, “3-D Stress Criteria Guidelines for Applications.” [S0094-9930(00)01601-2]

Reflections on the Federal Council of Churches, the United Church of Canada and the Social Gospel in the 1930s

What role did the United Church play in the 1930s as an affiliated member of the Federal Council of the Churches of Christ in America? This is a question which came to mind when I was asked by the editors to consider the theme of the social gospel in the United Church of Canada in comparison with developments in the United States. I chose as my basic sources two sets of printed but not readily available materials. I first read the reports of the Federal Council's meetings from 1928 to 1950, which happily include the minutes of its executive committee. They proved to be a mine of information, but made me hunger and thirst after scattered supportive archival documents of various kinds, such as correspondence, memoranda, personnel records, preliminary drafts and subcommittee reports. Then I scanned the issues of the Federal Council Bulletin from 1924 to 1944, published for most of that period ten times a year under the editorship of the Federal Council's general secretary, Samuel McCrea Cavert. The Bulletin proved helpful for sensing the changing moods of those times in Council circles, but again left me wanting to dig deeper into the archives. In this article I am going to risk some generalizations as hypotheses, primarily on the basis of those two sets of materials, but relying for help on some of the prominent books on social Christianity in North America. Some of my interpretations may be a little (or even quite) wrong, for at times the meaning of certain passages has not been entirely clear to me, but I hope they may provide something of value for future research and writing.

Local stress factors of a pipe-nozzle under internal pressure

A comprehensive study of local pressure stresses at the juncture of a pipe-nozzle is presented. Currently, neither experimental nor analytical data exists that is sufficient for pressure vessel designers to analyze the local pressure stresses at the juncture of a pipe-nozzle. In order to provide a comprehensive database to calculate these pressure stresses, this paper, through a finite element technique, provides a series of local pressure stress factor plots as a function of pipe-nozzle geometrical parameter β (nozzle mean radius/pipe mean radius) with a range from 0.1 to 1.0 and γ (pipe mean radius/pipe thickness) with a range from 10 to 300. These local pressure stress components supplement the stress calculations presented by the Welding Research Council Bulletin 107 for other external loadings.

Testing for nonzero skew in maximum discharge runoff data

Water Resource Council Bulletin 17B (Interagency Advisory Committee on Water Data, 1982) recommends finding T‐year flood values by fitting stream gauge data with a log Pearson III distribution. A problem arising in using this method is that, as is well known, the estimator for the skew of this distribution is highly variable and the computed T‐year values are sensitive to the value of skew used. The variability in estimating the skew is studied in this note by computing operating characteristic curves which display the probability that a sample from a site with a nonzero skew will actually fall in a specific interval. In rough summary it is not usually possible to reject, at a high level of significance the hypothesis that the skew at a site is zero by using only the data available for that site.

Local Flexibilities in Cylindrical Shells Due to External Loadings (Design Paper)

A shortcoming in Welding Research Council Bulletin 107, “Local Stresses in Spherical and Cylindrical Shells Due to External Loadings,” Wichman et al. (1965, 1979), has been the absence of a method for determining the flexibilities of vessels under local loads. Bulletin 107 is based in part on the work of Bijlaard (1954, 1955, 1959). These works of Bijlaard contain sufficient data such that flexibilities can be determined graphically for cylindrical shells under local (nozzle) loads. A relatively simple graphic method is presented for determining the radial, circumferential rotational and longitudinal rotational flexibilities at nozzle connections in cylindrical vessels where radial and bending loads are introduced through the nozzle.

On the estimation of stress concentration and flexibility at nozzles in ellipsoidal vessel heads

The US Welding Research Council Bulletin Number 107 (WRC-107) is currently being used by many designers in the estimation of stress concentrations at nozzle-vessel junctures. The validity of the application of this design document to the case of nozzles in ellipsoidal vessel heads is studied in this paper. A number of comparisons of the stress intensity and flexibility at the nozzles between approximate approaches and the exact situation were made and discussed.

Calcium and Phosphorus Requirements of Growing Turkeys and Chickens

MANY published reports were considered by the Sub-Committee on Poultry Nutrition in the preparation of the National Research Council bulletin “Nutrient Requirements of Poultry” (1960). Since this bulletin was prepared, new data have appeared which suggest that under favorable conditions, the requirements for calcium and phosphorus may be substantially lower than those given in the NRC publication. Davis (1959) has pointed out the adverse effects of excess calcium on the absorption of other nutrients.Several reports (Simco and Stephenson, 1960; Vanderpopuliere and Harms, 1960; Watts and Davis, 1960; White-Stevens, Pensack and Stokstad, 1960) indicated that good chick growth and normal calcification could be obtained with 0.6% to 0.8% calcium and 0.6% phosphorus. Under practical conditions, excess minerals tend to reduce growth and impair feed utilization (Fuller, 1960; Supplee et al., 1960; Smith and Taylor, 1961). The requirements of turkey poults for minerals were of special interest because of the high …
