  2. Google Internet searches on residency applicants do not facilitate the ranking process. (United States)

    Shin, Nara C; Ramoska, Edward A; Garg, Manish; Rowh, Adam; Nyce, Drew; Deroos, Francis; Carter, Merle; Hall, Ronald V; Lopez, Bernard L


    Information used by program directors (PDs) to evaluate and rank residency applicants is largely limited to the Electronic Residency Application Service and the interview day. The Internet represents a potential source of additional data on applicants. Recent surveys reveal that up to 90% of United States (US) companies are already using the Internet to post jobs and to screen candidates. However, its use in residency applicant evaluation is not well studied. We hypothesize that the Internet, through the use of a Google search, will provide useful information to PDs in ranking applicants. This prospective observational study was completed by six Accreditation Council for Graduate Medical Education-accredited Emergency Medicine residency programs. After the interview process, programs formed their rank order list in their usual fashion. Then participating programs performed a Google search on applicants from their list. A standardized search was used and information reviewed was limited to the first two Google pages. The main outcome measure was change in an applicant's status on the rank order list. Change in status was based on the judgment of the individual program's PD. A total of 547 applicants were reviewed. The time for review of information was 4,386 min total and a mean of 7.2 min per resident. Position on the rank order list was changed for three applicants; two moved up on the list and one moved down. Four programs made no changes. No applicants were removed. The Internet, through the use of a Google search, did not appear to provide useful information in a time-effective manner to PDs in ranking applicants. Copyright © 2013 Elsevier Inc.

  3. The influence of the residency application process on the online social networking behavior of medical students: a single institutional study. (United States)

    Strausburg, Matthew B; Djuricich, Alexander M; Carlos, W Graham; Bosslet, Gabriel T


    To evaluate medical students' behavior regarding online social networks (OSNs) in preparation for the residency matching process. The specific aims were to quantify the use of OSNs by students to determine whether and how these students were changing OSN profiles in preparation for the residency application process, and to determine attitudes toward residency directors using OSNs as a screening method to evaluate potential candidates. An e-mail survey was sent to 618 third- and fourth-year medical students at Indiana University School of Medicine over a three-week period in 2012. Statistical analysis was completed using nonparametric statistical tests. Of the 30.1% (183/608) who responded to the survey, 98.9% (181/183) of students reported using OSNs. More than half, or 60.1% (110/183), reported that they would (or did) alter their OSN profile before residency matching. Respondents' opinions regarding the appropriateness of OSN screening by residency directors were mixed; however, most respondents did not feel that their online OSN profiles should be used in the residency application process. The majority of respondents planned to (or did) alter their OSN profile in preparation for the residency match process. The majority believed that residency directors are screening OSN profiles during the matching process, although most did not believe their OSN profiles should be used in the residency application process. This study implies that the more medical students perceive that residency directors use social media in application screening processes, the more they will alter their online profiles to adapt to protect their professional persona.

  4. Plagiarism in residency application essays. (United States)

    Segal, Scott; Gelfand, Brian J; Hurwitz, Shelley; Berkowitz, Lori; Ashley, Stanley W; Nadel, Eric S; Katz, Joel T


    Anecdotal reports suggest that some residency application essays contain plagiarized content. To determine the prevalence of plagiarism in a large cohort of residency application essays. Retrospective cohort study. 4975 application essays submitted to residency programs at a single large academic medical center between 1 September 2005 and 22 March 2007. Specialized software was used to compare residency application essays with a database of Internet pages, published works, and previously submitted essays and the percentage of the submission matching another source was calculated. A match of more than 10% to an existing work was defined as evidence of plagiarism. Evidence of plagiarism was found in 5.2% (95% CI, 4.6% to 5.9%) of essays. The essays of non-U.S. citizens were more likely to demonstrate evidence of plagiarism. Other characteristics associated with the prevalence of plagiarism included medical school location outside the United States and Canada; previous residency or fellowship; lack of research experience, volunteer experience, or publications; a low United States Medical Licensing Examination Step 1 score; and non-membership in the Alpha Omega Alpha Honor Medical Society. The software database is probably incomplete, the 10%-match threshold for defining plagiarism has not been statistically validated, and the study was confined to applicants to 1 institution. Evidence of matching content in an essay cannot be used to infer the applicant's intent and is not sensitive to variations in the cultural context of copying in some societies. Evidence of plagiarism in residency application essays is more common in international applicants but was found in those by applicants to all specialty programs, from all medical school types, and even among applicants with significant academic honors.

  6. Use and utility of Web-based residency program information: a survey of residency applicants. (United States)

    Embi, Peter J; Desai, Sima; Cooney, Thomas G


    The Internet has become essential to the residency application process. In recent years, applicants and residency programs have used the Internet-based tools of the National Residency Matching Program (NRMP, the Match) and the Electronic Residency Application Service (ERAS) to process and manage application and Match information. In addition, many residency programs have moved their recruitment information from printed brochures to Web sites. Despite this change, little is known about how applicants use residency program Web sites and what constitutes optimal residency Web site content, information that is critical to developing and maintaining such sites. To study the use and perceived utility of Web-based residency program information by surveying applicants to an internal medicine program. Our sample population was the applicants to the Oregon Health & Science University Internal Medicine Residency Program who were invited for an interview. We solicited participation using the group e-mail feature available through the Electronic Residency Application Service Post-Office application. To minimize the possibility for biased responses, the study was confined to the period between submission of National Residency Matching Program rank-order lists and release of Match results. Applicants could respond using an anonymous Web-based form or by reply to the e-mail solicitation. We tabulated responses, calculated percentages for each, and performed a qualitative analysis of comments. Of the 431 potential participants, 218 responded (51%) during the study period. Ninety-nine percent reported comfort browsing the Web; 52% accessed the Web primarily from home. Sixty-nine percent learned about residency Web sites primarily from residency-specific directories while 19% relied on general directories. Eighty percent found these sites helpful when deciding where to apply, 69% when deciding where to interview, and 36% when deciding how to rank order programs for the Match. Forty

  7. Improving reliability of a residency interview process. (United States)

    Peeters, Michael J; Serres, Michelle L; Gundrum, Todd E


    To improve the reliability and discrimination of a pharmacy resident interview evaluation form, and thereby improve the reliability of the interview process. In phase 1 of the study, authors used a Many-Facet Rasch Measurement model to optimize an existing evaluation form for reliability and discrimination. In phase 2, interviewer pairs used the modified evaluation form within 4 separate interview stations. In phase 3, 8 interviewers individually-evaluated each candidate in one-on-one interviews. In phase 1, the evaluation form had a reliability of 0.98 with person separation of 6.56; reproducibly, the form separated applicants into 6 distinct groups. Using that form in phase 2 and 3, our largest variation source was candidates, while content specificity was the next largest variation source. The phase 2 g-coefficient was 0.787, while confirmatory phase 3 was 0.922. Process reliability improved with more stations despite fewer interviewers per station-impact of content specificity was greatly reduced with more interview stations. A more reliable, discriminating evaluation form was developed to evaluate candidates during resident interviews, and a process was designed that reduced the impact from content specificity.

  8. Do otolaryngology residency applicants relocate for training? (United States)

    Gebhard, Grant M; Hauser, Leah J; Dally, Miranda J; Weitzenkamp, David A; Cabrera-Muffly, Cristina


    To determine whether there is an association between the geographic location of an applicant's undergraduate school, medical school, and residency program among matched otolaryngology residency applicants. Observational. Otolaryngology residency program applications to our institution from 2009 to 2013 were analyzed. The geographic location of each applicant's undergraduate education and medical education were collected. Online public records were queried to determine the residency program location of matched applicants. Applicants who did not match or who attended medical school outside the United States were excluded. Metro area, state, and region were determined according to US Census Bureau definitions. From 2009 to 2013, 1,089 (78%) of 1,405 applicants who matched into otolaryngology residency applied to our institution. The number of subjects who attended medical school and residency in the same geographic region was 241 (22%) for metropolitan area, 305 (28%) for state, and 436 (40%) for region. There was no difference in geographic location retention by gender or couples match status of the subject. United States Medical Licensing Exam step 1 scores correlated with an increased likelihood of subjects staying within the same geographic region (P = .03). Most otolaryngology applicants leave their previous geographic area to attend residency. Based on these data, the authors recommend against giving weight to geography as a factor when inviting applicants to interview.

  9. Emergency Medicine Residency Applicant Characteristics Associated with Measured Adverse Outcomes During Residency

    Directory of Open Access Journals (Sweden)

    Jesse Bohrer-Clancy


    Full Text Available Introduction Negative outcomes in emergency medicine (EM programs use a disproportionate amount of educational resources to the detriment of other residents. We sought to determine if any applicant characteristics identifiable during the selection process are associated with negative outcomes during residency. Methods Primary analysis consisted of looking at the association of each of the descriptors including resident characteristics and events during residency with a composite measure of negative outcomes. Components of the negative outcome composite were any formal remediation, failure to complete residency, or extension of residency. Results From a dataset of 260 residents who completed their residency over a 19-year period, 26 (10% were osteopaths and 33 (13% were international medical school graduates A leave of absence during medical school (p <.001, failure to send a thank-you note (p=.008, a failing score on United States Medical Licensing Examination Step I (p=.002, and a prior career in health (p=.034 were factors associated with greater likelihood of a negative outcome. All four residents with a “red flag” during their medicine clerkships experienced a negative outcome (p <.001. Conclusion “Red flags” during EM clerkships, a leave of absence during medical school for any reason and failure to send post-interview thank-you notes may be associated with negative outcomes during an EM residency.

  10. The Economic Burden of Orthopedic Surgery Residency Interviews on Applicants. (United States)

    Fogel, Harold A; Finkler, Elissa S; Wu, Karen; Schiff, Adam P; Nystrom, Lukas M


    The intense competition for orthopedic surgery residency positions influences the interview process. The financial impact on residency applicants is less well understood. The purpose of the present study was to define the economic burden of the orthopedic surgery residency interview process while additionally describing how applicants finance the expense. We distributed surveys to 48 nonrotating applicants at our institution's residency interview days for the 2015 match year. The survey consisted of eleven questions specific to the costs of interviewing for orthopedic surgery residency positions. The survey response rate was 90% (43/48). Applicants applied to a median of 65 orthopedic surgery residency programs (range 21-88) and targeted a median of 15 interviews (range 12-25). The mean cost estimate for a single interview was $450 (range $200-800) and the cost estimate for all interviews was $7,119 (range $2,500-15,000). Applicants spent a mean of $344 (range $0-750) traveling to our interview. Seventy-two percent borrowed money to finance their interview costs and 28% canceled interviews for financial reasons. The financial cost of interviewing for orthopedic surgery is substantial and a majority of applicants add to their educational debt by taking out loans to finance interviews. Future considerations should be made to minimize these costs for an already financially burdened population.

  11. Coal liquefaction process streams characterization and evaluation: Application of liquid chromatographic separation methods to THF-soluble portions of integrated two-stage coal liquefaction resids

    Energy Technology Data Exchange (ETDEWEB)

    Green, J.B.; Pearson, C.D.; Young, L.L.; Green, J.A. [National Inst. for Petroleum and Energy Research, Bartlesville, OK (United States)


    This study demonstrated the feasibility of using non-aqueous ion exchange liquid chromatography (NIELC) for the examination of the tetrahydrofuran (THF)-soluble distillation resids and THF-soluble whole oils derived from direct coal liquefaction. The technique can be used to separate the material into a number of acid, base, and neutral fractions. Each of the fractions obtained by NIELC was analyzed and then further fractionated by high-performance liquid chromatography (HPLC). The separation and analysis schemes are given in the accompanying report. With this approach, differences can be distinguished among samples obtained from different process streams in the liquefaction plant and among samples obtained at the same sampling location, but produced from different feed coals. HPLC was directly applied to one THF-soluble whole process oil without the NIELC preparation, with limited success. The direct HPLC technique used was directed toward the elution of the acid species into defined classes. The non-retained neutral and basic components of the oil were not analyzable by the direct HPLC method because of solubility limitations. Sample solubility is a major concern in the application of these techniques.

  12. The electronic residency application service application can predict accreditation council for graduate medical education competency-based surgical resident performance. (United States)

    Tolan, Amy M; Kaji, Amy H; Quach, Chi; Hines, O Joe; de Virgilio, Christian


    Program directors often struggle to determine which factors in the Electronic Residency Application Service (ERAS) application are important in the residency selection process. With the establishment of the Accreditation Council for Graduate Medical Education (ACGME) competencies, it would be important to know whether information available in the ERAS application can predict subsequent competency-based performance of general surgery residents. This study is a retrospective correlation of data points found in the ERAS application with core competency-based clinical rotation evaluations. ACGME competency-based evaluations as well as technical skills assessment from all rotations during residency were collected. The overall competency score was defined as an average of all 6 competencies and technical skills. A total of77 residents from two (one university and one community based university-affiliate) general surgery residency programs were included in the analysis. Receiving honors for many of the third year clerkships and AOA membership were associated with a number of the individual competencies. USMLE scores were predictive only of Medical Knowledge (p = 0.004). Factors associated with higher overall competency were female gender (p = 0.02), AOA (p = 0.06), overall number of honors received (p = 0.04), and honors in Ob/Gyn (p = 0.03) and Pediatrics (p = 0.05). Multivariable analysis showed honors in Ob/Gyn, female gender, older age, and total number of honors to be predictive of a number of individual core competencies. USMLE scores were only predictive of Medical Knowledge. The ERAS application is useful for predicting subsequent competency based performance in surgical residents. Receiving honors in the surgery clerkship, which has traditionally carried weight when evaluating a potential surgery resident, may not be as strong a predictor of future success.

  13. Residence time and physical processes in lakes

    Directory of Open Access Journals (Sweden)

    Nicoletta SALA


    Full Text Available The residence time of a lake is highly dependent on internal physical processes in the water mass conditioning its hydrodynamics; early attempts to evaluate this physical parameter emphasize the complexity of the problem, which depends on very different natural phenomena with widespread synergies. The aim of this study is to analyse the agents involved in these processes and arrive at a more realistic definition of water residence time which takes account of these agents, and how they influence internal hydrodynamics. With particular reference to temperate lakes, the following characteristics are analysed: 1 the set of the lake's caloric components which, along with summer heating, determine the stabilizing effect of the surface layers, and the consequent thermal stratification, as well as the winter destabilizing effect; 2 the wind force, which transfers part of its momentum to the water mass, generating a complex of movements (turbulence, waves, currents with the production of active kinetic energy; 3 the water flowing into the lake from the tributaries, and flowing out through the outflow, from the standpoint of hydrology and of the kinetic effect generated by the introduction of these water masses into the lake. These factors were studied in the context of the general geographical properties of the lake basin and the watershed (latitude, longitude, morphology, also taking account of the local and regional climatic situation. Also analysed is the impact of ongoing climatic change on the renewal of the lake water, which is currently changing the equilibrium between lake and atmosphere, river and lake, and relationships

  14. Under the microscope: assessing surgical aptitude of otolaryngology residency applicants. (United States)

    Carlson, Matthew L; Archibald, David J; Sorom, Abraham J; Moore, Eric J


    Application to otolaryngology residency is a highly competitive process. Programs identify the best candidates by evaluating academic performance in medical school, board scores, research experience, performance during an interview, and letters of recommendation. Unfortunately, none of these metrics completely assess an applicant's capacity to learn and perform surgical skills. We describe a direct assessment of an applicant's ability for rapid surgical skill acquisition, manual dexterity, and response to stress that can be performed during the interview process. A retrospective study at an academic otolaryngology residency program. After orientation, applicants were seated at a microsurgical training station and allotted 20 minutes to suture an incision using 10-0 nylon suture on a latex practice card. Their performance was graded using a 1-to-5 scoring system for the following categories: microscope use, respect for tissue, instrument handling, knot tying and suture control, skills acquisition, and attitude toward the exercise. Applicants were given some instruction and assessed on their ability to incorporate what they had learned into their technique. The average total applicant score was 23.2, standard deviation (SD) 3.6 (maximum 30); 13.4% of applicants scored 1 SD above the mean. The value of applicant screening tests in predicting surgical competency is controversial. We describe a direct assessment tool that may prove useful in identifying outliers, both high and low, to aid in final applicant ranking.

  15. Residency applicants prefer online system for scheduling interviews. (United States)

    Wills, Charlotte; Hern, H Gene; Alter, Harrison


    Residency coordinators may be overwhelmed when scheduling residency interviews. Applicants often have to coordinate interviews with multiple programs at once, and relying on verbal or email confirmation may delay the process. Our objective was to determine applicant mean time to schedule and satisfaction using online scheduling. This pilot study is a retrospective analysis performed on a sample of applicants offered interviews at an urban county emergency medicine residency. Applicants were asked their estimated time to schedule with the online system compared to their average time using other methods. In addition, they were asked on a five-point anchored scale to rate their satisfaction. Of 171 applicants, 121 completed the survey (70.8%). Applicants were scheduling an average of 13.3 interviews. Applicants reported scheduling interviews using the online system in mean of 46.2 minutes (median 10, range 1-1800) from the interview offer as compared with a mean of 320.2 minutes (median 60, range 3-2880) for other programs not using this system. This difference was statistically significant. In addition, applicants were more likely to rate their satisfaction using the online system as "satisfied" (83.5% vs 16.5%). Applicants were also more likely to state that they preferred scheduling their interviews using the online system rather than the way other programs scheduled interviews (74.2% vs 4.1%) and that the online system aided them coordinating travel arrangements (52.1% vs 4.1%). An online interview scheduling system is associated with higher satisfaction among applicants both in coordinating travel arrangements and in overall satisfaction.

  16. A theory-informed, process-oriented Resident Scholarship Program. (United States)

    Thammasitboon, Satid; Darby, John B; Hair, Amy B; Rose, Karen M; Ward, Mark A; Turner, Teri L; Balmer, Dorene F


    The Accreditation Council for Graduate Medical Education requires residency programs to provide curricula for residents to engage in scholarly activities but does not specify particular guidelines for instruction. We propose a Resident Scholarship Program that is framed by the self-determination theory (SDT) and emphasize the process of scholarly activity versus a scholarly product. The authors report on their longitudinal Resident Scholarship Program, which aimed to support psychological needs central to SDT: autonomy, competence, and relatedness. By addressing those needs in program aims and program components, the program may foster residents' intrinsic motivation to learn and to engage in scholarly activity. To this end, residents' engagement in scholarly processes, and changes in perceived autonomy, competence, and relatedness were assessed. Residents engaged in a range of scholarly projects and expressed positive regard for the program. Compared to before residency, residents felt more confident in the process of scholarly activity, as determined by changes in increased perceived autonomy, competence, and relatedness. Scholarly products were accomplished in return for a focus on scholarly process. Based on our experience, and in line with the SDT, supporting residents' autonomy, competence, and relatedness through a process-oriented scholarship program may foster the curiosity, inquisitiveness, and internal motivation to learn that drives scholarly activity and ultimately the production of scholarly products.

  17. Residence time modeling of hot melt extrusion processes. (United States)

    Reitz, Elena; Podhaisky, Helmut; Ely, David; Thommes, Markus


    The hot melt extrusion process is a widespread technique to mix viscous melts. The residence time of material in the process frequently determines the product properties. An experimental setup and a corresponding mathematical model were developed to evaluate residence time and residence time distribution in twin screw extrusion processes. The extrusion process was modeled as the convolution of a mass transport process described by a Gaussian probability function, and a mixing process represented by an exponential function. The residence time of the extrusion process was determined by introducing a tracer at the extruder inlet and measuring the tracer concentration at the die. These concentrations were fitted to the residence time model, and an adequate correlation was found. Different parameters were derived to characterize the extrusion process including the dead time, the apparent mixing volume, and a transport related axial mixing. A 2(3) design of experiments was performed to evaluate the effect of powder feed rate, screw speed, and melt viscosity of the material on the residence time. All three parameters affect the residence time of material in the extruder. In conclusion, a residence time model was developed to interpret experimental data and to get insights into the hot melt extrusion process. Copyright © 2013 Elsevier B.V. All rights reserved.

  18. Improving applicant selection: identifying qualities of the unsuccessful otolaryngology resident. (United States)

    Badran, Karam W; Kelley, Kanwar; Conderman, Christian; Mahboubi, Hossein; Armstrong, William B; Bhandarkar, Naveen D


    To identify the prevalence and management of problematic residents. Additionally, we hope to identify the factors associated with successful remediation of unsuccessful otolaryngology residents. Self-reported Internet and paper-based survey. An anonymous survey was distributed to 152 current and former program directors (PDs) in 2012. The factors associated with unsuccessful otolaryngology residents and those associated with the successful remediation of problematic residents were investigated. An unsuccessful resident is defined as one who quit or was removed from the program for any reason, or one whose actions resulted in criminal action or citation against their medical license after graduation from residency. Remediation is defined as an individualized program implemented to correct documented weaknesses. The overall response rate was 26% (40 PDs). Seventy-three unsuccessful or problematic residents were identified. Sixty-six problematic or unsuccessful residents were identified during residency, with 58 of 66 (88%) undergoing remediation. Thirty-one (47%) residents did not graduate. The most commonly identified factors of an unsuccessful resident were: change in specialty (21.5%), interpersonal and communication skills with health professionals (13.9%), and clinical judgment (10.1%). Characteristics of those residents who underwent successful remediation include: poor performance on in-training examination (17%, P otolaryngology PDs in this sample identified at least one unsuccessful resident. Improved methods of applicant screening may assist in optimizing otolaryngology resident selection. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

  19. Opinions of Otorhinolaryngology Residents about Their Education Process. (United States)

    Dokuzlar, Uğur; Miman, Murat Cem; Denizoğlu, İsmail İlter; Eğrilmez, Murat


    Our study was planned to get the views of residents about the Otorhinolaryngology (ORL) education process and to enlighten the studies to make this process more effective. A questionnaire was sent to the residents who were still in the residency program in all education clinics via "Google Drive". Seventy-four of 354 residents responded and the answers were evaluated electronically. Fifty residents (67.56%) gave an affirmative answer to the question about the use of "Resident Log Book" and no difference was seen among the clinics. While 9 residents (12.16%) were reporting that they did not read any scientific papers, 43 (58.1%) reported they read less than three per month. Forty-one residents thougt that they were having a good and sufficient education. Seventeen residents (51.51%) who thought they were not having a sufficient education reported that the education period should be longer. When they were wanted to evaluate the education process, while 66 of them (89.18%) said "Exhausting", 52 (70.27%) said "Stressful", it was seen that the ones who said "Instructive" and "Rewarding" were 26 (35.13%) and 17 (22.97%) respectively. Further, 43 of 48 residents (89.58%) who were over the third year of their residency program indicated that they were unable to perform at least one procedure listed in the questionnaire after finishing their education. This study is important because it is the first study about the opinion of ORL residents and will help determine the current status in Turkey. This study will be useful for the preparation of educational programs and guides in the future.

  20. Analysis of a Resident Aesthetic Clinic: Process for Rhinoplasty, Resident Experience, and Patient Satisfaction. (United States)

    Brandel, Michael G; DʼSouza, Gehaan F; Reid, Christopher M; Dobke, Marek K; Gosman, Amanda A


    Plastic surgery residents often desire additional training in rhinoplasty than what is provided by their residency program. The goal of this study was to define and evaluate a specific process used to structure preoperative, intraoperative, and postoperative protocols for rhinoplasty patients in the resident aesthetic clinic (RAC) to enhance qualitative and quantitative experience. Complication rates and patient/resident satisfaction scores were also examined. Resident clinic rhinoplasty patients underwent a well-defined and established process that included patient education and informed consent, preoperative planning in a conference-based session, specific adherence to established surgical techniques, and structured postoperative management and follow-up. This process also included supervision criteria for residents in the operating room and clinical setting. Patient and resident satisfaction at the RAC was evaluated by a Web-based survey. A database of procedural complications and methods was compiled and evaluated. Between June 2012 and June 2015, 146 aesthetic resident cases were completed through the University of California, San Diego Residency Aesthetic Surgery Program. Of these cases, 34 (17%) were rhinoplasty procedures. Residents at our institution assisted on an average of 55 rhinoplasty procedures with the faculty and performed an average of 12 rhinoplasty procedures as primary surgeons. The residents surveyed felt that they had a good autonomous experience (P < 0.001), and 90% reported confidence with rhinoplasty. Postoperative complications were recorded and included asymmetry (n = 4, 10.5%), septal perforation (n = 1, 2.6%), and difficulty in breathing (n = 6, 15.8%). There were no patients who experienced infections, and the complication rate requiring revision in the operating room was 0%. Optimizing protocols in rhinoplasty in an RAC has allowed for the RAC to flourish in the breadth and complexity of rhinoplasty operations. This has enabled

  2. The Burden of the Fellowship Interview Process on General Surgery Residents and Programs. (United States)

    Watson, Shawna L; Hollis, Robert H; Oladeji, Lasun; Xu, Shin; Porterfield, John R; Ponce, Brent A

    This study evaluated the effect of the fellowship interview process in a cohort of general surgery residents. We hypothesized that the interview process would be associated with significant clinical time lost, monetary expenses, and increased need for shift coverage. An online anonymous survey link was sent via e-mail to general surgery program directors in June 2014. Program directors distributed an additional survey link to current residents in their program who had completed the fellowship interview process. United States allopathic general surgery programs. Overall, 50 general surgery program directors; 72 general surgery residents. Program directors reported a fellowship application rate of 74.4%. Residents most frequently attended 8 to 12 interviews (35.2%). Most (57.7%) of residents reported missing 7 or more days of clinical training to attend interviews; these shifts were largely covered by other residents. Most residents (62.3%) spent over $4000 on the interview process. Program directors rated fellowship burden as an average of 6.7 on a 1 to 10 scale of disruption, with 10 being a significant disruption. Most of the residents (57.3%) were in favor of change in the interview process. We identified potential areas for improvement including options for coordinated interviews and improved content on program websites. The surgical fellowship match is relatively burdensome to residents and programs alike, and merits critical assessment for potential improvement. Published by Elsevier Inc.

  3. Residency Applicant Preferences of Online Systems for Scheduling Interviews. (United States)

    Hern, H Gene; Wills, Charlotte P; Alter, Harrison J; Bowman, Steven H; Burns, Boyd D; Loyd, Joshua; Schneider, Jeffrey I; Yarris, Lalena M


    Residency applicants often have difficulty coordinating interviews with multiple programs. An online scheduling system might improve this process. The authors sought to determine applicant mean time to schedule interviews and satisfaction using online scheduling compared with manual scheduling. An electronic survey was sent to US graduates applying to any of 6 emergency medicine programs in the 2014-2015 application cycle. Of the participant programs, 3 used an online system and 3 did not. Applicants were asked to report estimated time to schedule with the online system compared to their average time using other methods, and to rate their satisfaction with the scheduling process. Of 1720 applicants to at least 1 of the 6 programs, 856 completed the survey (49.8%). Respondents reported spending less time scheduling interviews using the online system compared to other systems (median of 5 minutes [IQR 3-10] versus 60 minutes [IQR 15-240], respectively, P interviews using the online system (91.5% versus 11.0%, P interview scheduling system is associated with time savings for applicants as well as higher satisfaction among applicants, both in ease of scheduling and in coordinating travel arrangements. The results likely are generalizable to other medical and surgical specialties.

    To determine what factors residency program directors (RPDs) consider and what methods they use to assess applicants. Respondents ranked the importance of 27 applicant features within domains: academics/credentials, application features/program fit, involvement, professional experience, research/ teaching experience, and postgraduate year 1 (PGY-1) residency experience. Rank was assigned in an ordinal fashion (1 = most important feature). The domains were characterized by their importance (mean % ± SD) in selecting candidates for interviews. Participants characterized their screening process according to 8 application and 6 interview features and the corresponding applicant dimensions evaluated. RPDs rated the importance of 14 methods applicants used to communicate with the program and 3 methods by which references were obtained. A Likert scale was used for rating (4 = crucial features). The approaches the program used to evaluate 12 application features or interpersonal interactions were reported. The most important application domain was application features/program fit (26.28 ± 19.11). The highest ranked application feature was program fit (2.04 ± 1.17). The applicant's cover letter, recommendation letters, curriculum vitae, and interview meal were commonly used to assess communication and interpersonal skills, knowledge base, and experience. The most important communication venue was the on-site interview (3.95 ± 0.23). Recommendations solicited by RPDs (3.42 ± 0.69) were most important. Programs formally evaluated the interview (89%) and recommendation letters (84%). Understanding the importance that RPDs place on application and interview features, as well as the process used to assess communication skills and interpersonal interactions, should allow residency candidates to become more competitive residency prospects.

  5. Documenting resident procedure and diagnostic experience: simplifying the process. (United States)

    Baldor, R A; Broadhurst, J


    The Residency Review Committee (RRC) requires documentation of family practice residents' procedural and diagnostic experiences. Further, hospital privileging is frequently based on documentation of prior clinical experience. Residency programs need a user-friendly (ie, resident-friendly) mechanism for collecting data and generating reports to document these experiences. This paper outlines a simplified, user-friendly method of documenting resident procedural and diagnostic experiences. We developed a pocket-sized, optically scannable card for data input. This is coupled with a computerized database with report generation capability. The system is based on diagnostic clusters to further simplify the data input process. The system's setup costs are about $10,000. Annual maintenance and operational fees are about $5,000. After instituting the system, the number of residents submitting documentation information increased substantially. This system meets both RRC and potential clinical privileging requirements and provides a useful tool for guiding resident evaluation and developing appropriate training opportunities during the latter half of the residency. Simplified, accurate documentation may allow for comparisons among residents at various levels--program, state, and national.

  7. Surgical residency market research-what are applicants looking for? (United States)

    Parker, Anna M; Petroze, Robin T; Schirmer, Bruce D; Calland, James F


    We propose that one of the integral parts of building a stronger residency program is the ability to recruit top applicants. Little is known about the factors applicants use to evaluate residency programs. Given that the top applicants are likely to be ranked highly by multiple programs, we sought to determine which factors applicants themselves used to evaluate potential residency programs. An anonymous, voluntary survey was distributed to all interviewing applicants, asking them to rank 12 factors when choosing a residency. They were additionally asked about any prior research or international medical experience. Surveys were distributed at the beginning of the interview day and collected in sealed unmarked envelopes. All applicants interviewing for general surgery residency at the University of Virginia during the 2009-2010 and 2010-2011 seasons. Resident satisfaction was rated the highest, 8.7 out of 9. In descending order of importance, applicants ranked record of the chiefs (8.0), resident case volume (7.8), academic reputation (7.6), geography (7.4), research opportunities (7.3), laparoscopic laboratory (6.2), elective time (5.4), international opportunities (5.1), benefits (4.8), and vacation (4.7), respectively. No correlation was found between prior research experience and research ranking score. A significant positive correlation was found between those applicants with prior international experience and their ranking of international opportunities during residency (p < 0.0001). Applicants rated a program on a broad range of factors and commonly cited a "gut feeling" or "esprit de corps." The ability to pursue an identified area of special interest, in this case an international opportunity, proved to be an additional major selection factor for a subset of candidates.

  8. Demographics and quality profile of applicants to pediatric dentistry residencies. (United States)

    Isharani, Sona J; Litch, C Scott; Romberg, Elaine; Wells, Anne; Rutkauskas, John S


    The purpose of this study was to use Postdoctoral Application Support Service (PASS) data to study the quality and demographic trends for pediatric dentistry residency applicants. PASS data on grade point average (GPA) and National Dental Board Exam, Part I (NBI) scores were used to determine applicant quality. PASS demographic data included: (1) gender; (2) citizenship; (3) ethnicity; (4) previous practice of dentistry; and (5) completion of a residency or internship. GPAs showed a significant increase for the 6 years investigated. NBI scores also indicated a significant increase. Significantly more females than males applied to pediatric dentistry residencies. A significant increase in US/Canadian applicants was found. Ethnicity was similar to that of dental school graduates, with minor exceptions. In several of the years studied, there were significant differences in applicants who previously practiced dentistry or completed a residency/internship vs applicants who had no such previous experience. Significant increases in grade point averages and National Dental Board Exam, Part I scores suggest a high quality of pediatric dentistry residency applicants and this trend seem to be continuing. There are significantly more female than male applicants. More research is warranted on actual acceptance data.

  9. Influence of social networking websites on medical school and residency selection process. (United States)

    Schulman, Carl I; Kuchkarian, Fernanda M; Withum, Kelly F; Boecker, Felix S; Graygo, Jill M


    Social networking (SN) has become ubiquitous in modern culture. The potential consequences of revealing personal information through SN websites are not fully understood. To assess familiarity with, usage of, and attitudes towards, SN websites by admissions offices at US medical schools and residency programmes. A 26-question survey was distributed in autumn 2009 to 130 US medical school admissions officers and 4926 residency programme directors accredited by the Accreditation Council for Graduate Medical Education. A total of 600 surveys were completed, with 46 (8%) respondents who self-identified as reviewing only medical school applications, 511 (85%) who reported reviewing residency programme applications and 43 (7%) who reported reviewing both. 90/600 (15%) medical schools or programmes maintain profiles on SN websites and 381/600 (64%) respondents reported being somewhat or very familiar with searching individual profiles on SN websites. While a minority of medical schools and residency programmes routinely use SN websites in the selection process (53/600; 9%), more than half of respondents felt that unprofessional information on applicants' SN websites could compromise their admission into medical school or residency (315/600; 53%). SN websites will affect selection of medical students and residents. Formal guidelines for professional behaviour on SN websites might help applicants avoid unforeseen bias in the selection process.

  10. Can Future Academic Surgeons be Identified in the Residency Ranking Process? (United States)

    Beninato, Toni; Kleiman, David A; Zarnegar, Rasa; Fahey, Thomas J


    The goal of surgical residency training programs is to train competent surgeons. Academic surgical training programs also have as a mission training future academicians-surgical scientists, teachers, and leaders. However, selection of surgical residents is dependent on a relatively unscientific process. Here we sought to determine how well the residency selection process is able to identify future academicians in surgery. Rank lists from an academic surgical residency program from 1992 to 1997 were examined. All ranked candidates׳ career paths after residency were reviewed to determine whether they stayed in academics, were university affiliated, or in private practice. The study was performed at New York Presbyterian Hospital-Weill Cornell Medical College, New York, NY. A total of 663 applicants for general surgery residency participated in this study. In total 6 rank lists were evaluated, which included 663 candidates. Overall 76% remained in a general surgery subspecialty. Of those who remained in general surgery, 49% were in private practice, 20% were university affiliated, and 31% had academic careers. Approximately 47% of candidates that were ranked in the top 20 had ≥20 publications, with decreasing percentages as rank number increased. There was a strong correlation between the candidates׳ rank position and pursuing an academic career (p career.

  12. "Ghost" publications among applicants to a general surgery residency program. (United States)

    Kuo, Paul C; Schroeder, Rebecca A; Shah, Anand; Shah, Jatin; Jacobs, Danny O; Pietrobon, Ricardo


    To determine the incidence of potentially fraudulent (or "ghost") publications in applications to a general surgery residency program. Electronic Residency Application Services applications submitted in 2005 to the general surgery residency program were reviewed in an IRB-approved study. No identifiers were collected. Publications were checked against Medline, PubMed, ISI Web of Science, and Google. Nonverifiable publications were then submitted to the medical librarian for verification. Ghost publications were defined as journals, books, or meetings that cannot be verified; verified journals without the listed publication; or verified publications without an applicant author. Data analyses were performed using univariate and multivariate regression analysis for nonparametric data. A p value publications, including 30 abstracts, 359 journal articles, and 207 chapters. Thirty-three percent (196 of 596) of the publications could not be verified: 7 abstracts, 177 journal articles, and 12 chapters. The distribution of ghost publications was skewed toward the journals subgroup (p publications were age and foreign medical school. The sole negative predictor was enrollment in a top-10 US research medical school. A disturbingly substantial fraction of publications listed on Electronic Residency Application Services applications cannot be verified. This might indicate a need for greater mentorship and oversight for medical school applicants. It is unknown whether this behavior predicts lack of integrity in other professional settings.

  13. Plagiarism in Personal Statements of Anesthesiology Residency Applicants. (United States)

    Parks, Lance J; Sizemore, Daniel C; Johnstone, Robert E


    Plagiarism by residency applicants in their personal statements, as well as sites that sell personal statements, have been described, and led in 2011 to advice to avoid plagiarism and the caution that plagiarism detection software was available. We screened personal statements of 467 anesthesiology residency applicants from 2013-2014 using Viper Plagiarism Scanner software, and studied them for plagiarism. After quotes and commonly used phrases were removed, 82 statements contained unoriginal content of 8 or more consecutive words. After the study, 13.6% of personal statements from non-United States medical school graduates, and 4.0% from United States medical school graduates, contained plagiarized material, a significant difference. Plagiarized content ranged up to 58%. Plagiarism continues to occur in anesthesiology residency personal statements, with a higher incidence among graduates of non-United States medical schools.

  15. Publication misrepresentation among neurosurgery residency applicants: an increasing problem. (United States)

    Kistka, Heather M; Nayeri, Arash; Wang, Li; Dow, Jamie; Chandrasekhar, Rameela; Chambless, Lola B


    OBJECT Misrepresentation of scholarly achievements is a recognized phenomenon, well documented in numerous fields, yet the accuracy of reporting remains dependent on the honor principle. Therefore, honest self-reporting is of paramount importance to maintain scientific integrity in neurosurgery. The authors had observed a trend toward increasing numbers of publications among applicants for neurosurgery residency at Vanderbilt University and undertook this study to determine whether this change was a result of increased academic productivity, inflated reporting, or both. They also aimed to identify application variables associated with inaccurate citations. METHODS The authors retrospectively reviewed the residency applications submitted to their neurosurgery department in 2006 (n = 148) and 2012 (n = 194). The applications from 2006 were made via SF Match and those from 2012 were made using the Electronic Residency Application Service. Publications reported as "accepted" or "in press" were verified via online search of Google Scholar, PubMed, journal websites, and direct journal contact. Works were considered misrepresented if they did not exist, incorrectly listed the applicant as first author, or were incorrectly listed as peer reviewed or published in a printed journal rather than an online only or non-peer-reviewed publication. Demographic data were collected, including applicant sex, medical school ranking and country, advanced degrees, Alpha Omega Alpha membership, and USMLE Step 1 score. Zero-inflated negative binomial regression was used to identify predictors of misrepresentation. RESULTS Using univariate analysis, between 2006 and 2012 the percentage of applicants reporting published works increased significantly (47% vs 97%, p percentage of applicants with misrepresentations (33% vs 45%) also increased. In 2012, applicants with a greater total of reported works (p < 0.001) and applicants from unranked US medical schools (those not ranked by US News

  17. Development of a Night Float Call Model for Obstetrics and Gynaecology Residency: The Process and Residents' Perceptions. (United States)

    Sterling, Lynn; McCaffrey, Carmen; Secter, Michael; Rich, Rebecca; Green, Jessica; Shirreff, Lindsay; Steele, Donna


    The 2013 pan-Canadian consensus Report on Resident Duty Hours identified that traditional 24-hour duty periods pose risks to the well-being of residents and should be avoided. In anticipation of duty-hour restrictions, the Obstetrics and Gynaecology Residency Program at the University of Toronto developed and implemented a night float (NF) call model over a three-year span. Quarterly resident surveys have consistently shown that the NF system is preferred to traditional 24-hour call and has resulted in reduced fatigue and improved continuity of patient care. Through many iterations, the NF model achieved levels of resident morale, surgical experience, and impact on family relationships that are comparable to the 24-hour call system. We review here our process for developing an NF call model and the perceptions and experiences of residents, with the goal of providing insight for other residency programs that are considering or instituting NF call systems.

  20. It was the night before the interview: perceptions of resident applicants about the preinterview reception. (United States)

    Schlitzkus, Lisa L; Schenarts, Paul J; Schenarts, Kimberly D


    Hosting a reception for prospective interns the evening before the interview has become a well-established expectation. It is thought that these initial impressions significantly influence the ranking process. Despite these well-held beliefs, there has been a paucity of studies exploring the preinterview reception. A survey tool was created and piloted to ensure validity. The survey was then administered to a fourth-year class of allopathic medical students immediately after interviews but before Match Day. A university, teaching hospital. Fourth-year allopathic medical students. The response rate was 100% (n = 69). Ninety-six percent of programs hosted an event. Although these events were minimally stressful (86%), the same percent felt that not attending would limit their knowledge of the program, and 66% felt that it would negatively affect their application. Forty percent believe this event to be extremely important to residency programs in selecting interns. Ninety-five percent are attended by residents only, and approximately half were at a casual restaurant. Most applicants (97%) never paid for their own meal, and 69% felt that if they did, it would leave a negative impression of the program. Candidates believe the preinterview reception is important in the selection process, that failing to attend would negatively affect their application, and provides insight about the program. Alcohol is often provided but rarely has a negative effect. Applicants prefer an informal setting with unfettered interactions with the residents. © 2013 Association of Program Directors in Surgery.

  3. Residency characteristics that matter most to plastic surgery applicants: a multi-institutional analysis and review of the literature. (United States)

    Sinno, Sammy; Mehta, Karan; Squitieri, Lee; Ranganathan, Kavitha; Koeckert, Michael S; Patel, Ashit; Saadeh, Pierre B; Thanik, Vishal


    The National Residency Matching Program Match is a very unique process in which applicants and programs are coupled to each other based on a ranking system. Although several studies have assessed features plastic surgery programs look for in applicants, no study in the present plastic surgery literature identifies which residency characteristics are most important to plastic surgery applicants. Therefore, we sought to perform a multi-institutional assessment as to which factors plastic surgery residency applicants consider most important when applying for residency. A validated and anonymous questionnaire containing 37 items regarding various program characteristics was e-mailed to 226 applicants to New York University, Albany, University of Michigan, and University of Southern California plastic surgery residency programs. Applicants were asked to rate each feature on a scale from 1 to 10, with 10 being the most important. The 37 variables were ranked by the sum of the responses. The median rating and interquartile range as well as the mean for each factor was then calculated. A Wilcoxon signed rank test was used to compare medians in rank order. A total of 137 completed questionnaires were returned, yielding a 61% response rate. The characteristics candidates considered most important were impressions during the interview, experiences during away rotations, importance placed on resident training/support/mentoring by faculty, personal experiences with residents, and the amount of time spent in general surgery. The characteristics candidates considered least important were second-look experiences, compensation/benefits, program reputation from Internet forums, accessibility of program coordinator, opportunity for laboratory research, and fellowship positions available at the program. Applicants value personal contact and time spent in general surgery when selecting residency programs. As the number of integrated programs continues to grow, programs will benefit

  6. The 2017 Integrated IR Residency Match: Results of a National Survey of Applicants and Program Directors. (United States)

    DePietro, Daniel M; Kiefer, Ryan M; Redmond, Jonas W; Hoffmann, Jason C; Trerotola, Scott O; Nadolski, Gregory J


    To characterize and compare the experiences of matched applicants and program directors (PDs) participating in the first large-scale integrated interventional radiology (IR) residency match. Survey questionnaires were distributed nationally to integrated IR applicants who matched in the 2017 Match cycle and PDs. Both groups were questioned regarding their experiences with the application, interview, rank, and match processes as well as applicant-specific and PD-specific information. Summary and descriptive statistics were applied to responses, and comparison of Likert scale responses was performed by two-sample t test. Sixty-one matched applicants (51.3%) and 34 PDs (55.7%) responded to the survey. Regarding the match process, applicants believed United States Medical Licensing Examination (USMLE) Step 1 score (P = .002) and connection to a program's geographic location (P = .006) were significantly more important than PDs did, whereas PDs ranked grades (P = .049), class rank (P = .011), academic awards (P = .003), additional degrees (P < .001), and USMLE Step 2 Clinical Skills score (P < .001) as significantly more important factors than applicants did. Additional information regarding demographic data, medical school experiences in IR, application strategies, interview experiences, rank lists, the intern year, and match results are reported. The completion of the first large-scale integrated IR match represents a paradigm shift in the way in which IR practitioners are recruited and trained. This study provides valuable benchmark data and analysis that can be used to improve efforts to match the best-fitting applicants into the integrated IR residency and improve future match cycles for applicants and PDs alike.

  7. Relationships between removal processes and residence times for atmospheric pollutants

    International Nuclear Information System (INIS)

    Slinn, W.G.N.


    This report is concerned with improving estimates for the residence times of atmospheric trace constituents in various atmospheric reservoirs. Residence times are defined only for steady-state conditions; i.e., when the net growth rate vanishes. The most useful case of vanishing net growth rate is when the total growth rate is equal to the decay rate. It is demonstrated that the most important advance towards improving estimates of pollutant residence times is through proper choices of reservoirs. Chosen reservoirs should possess the following features: steady-state conditions, uniform mixing ratio throughout or throughout specified subreservoirs, and subreservoirs chosen in which removal rates can be treated as approximate constants. An example of a poorly mixed reservoir, the stratosphere, is discussed. In another example, it is suggested that commonly used reservoirs for atmospheric CO 2 have been chosen poorly and that a substantial portion of the anthropogenic CO 2 released during the past 50 years may still be mixing into the stratosphere. In another example, it is suggested that determination of the dry deposition velocity for accumulation-mode aerosol particles may not be so important as previously thought. To improve estimates for the atmospheric residence times of these particles, it is important to increase knowledge of what is called the ascension velocity

  8. Comparative reliability of structured versus unstructured interviews in the admission process of a residency program. (United States)

    Blouin, Danielle; Day, Andrew G; Pavlov, Andrey


    Although never directly compared, structured interviews are reported as being more reliable than unstructured interviews. This study compared the reliability of both types of interview when applied to a common pool of applicants for positions in an emergency medicine residency program. In 2008, one structured interview was added to the two unstructured interviews traditionally used in our resident selection process. A formal job analysis using the critical incident technique guided the development of the structured interview tool. This tool consisted of 7 scenarios assessing 4 of the domains deemed essential for success as a resident in this program. The traditional interview tool assessed 5 general criteria. In addition to these criteria, the unstructured panel members were asked to rate each candidate on the same 4 essential domains rated by the structured panel members. All 3 panels interviewed all candidates. Main outcomes were the overall, interitem, and interrater reliabilities, the correlations between interview panels, and the dimensionality of each interview tool. Thirty candidates were interviewed. The overall reliability reached 0.43 for the structured interview, and 0.81 and 0.71 for the unstructured interviews. Analyses of the variance components showed a high interrater, low interitem reliability for the structured interview, and a high interrater, high interitem reliability for the unstructured interviews. The summary measures from the 2 unstructured interviews were significantly correlated, but neither was correlated with the structured interview. Only the structured interview was multidimensional. A structured interview did not yield a higher overall reliability than both unstructured interviews. The lower reliability is explained by a lower interitem reliability, which in turn is due to the multidimensionality of the interview tool. Both unstructured panels consistently rated a single dimension, even when prompted to assess the 4 specific domains

    Full Text Available This article presents an experience in software residence, addressing jointly, software product line and version control process. A residency program in software is conceptually similar to the medical residency programs, which aims to train professionals in an area/specific activity. A real scenario was presented to three groups of master's students who had a mission to develop and specify a process to meet a specific problem. As a result of this experiment, we developed the process and the software of residence contributed to knowledge on the scene was internalized and disseminated among the participants.

  10. Mutiny on the balint: balancing resident developmental needs with the balint process. (United States)

    Smith, Marcia; Anandarajah, Gowri


    Many residency training programs offer Balint groups as a means of encouraging residents in reflective practice. Residency Balint groups around the country are variable with regard to format when compared to the recommended structure. This paper describes a resident Balint group in which the residents initially expressed strong dissatisfaction with the group, although they understood its purpose and expected format and were committed to the group process and goals. The seminar was modified to address their concerns, and the subsequent group process was studied to evaluate the effect of the changes. The subjects were 11 second-year residents in a 13-13-13 program in the northeastern United States. A needs assessment using a qualitative survey and focus group-style discussion was performed. The immersion-crystallization method was used at all stages. Field notes from subsequent sessions, combined with leader reflections, captured the group process. The first sessions addressed requested professional development topics. The residents then spontaneously returned to a process more consistent with traditional Balint, although discussion of the patient perspective was infrequent. Our experience suggests that modification of Balint group structure and process may be necessary with some groups of learners to pave the way for a more meaningful Balint experience over the course of training.

  11. Integrity of the National Resident Matching Program for Radiation Oncology: National Survey of Applicant Experiences

    International Nuclear Information System (INIS)

    Holliday, Emma B.; Thomas, Charles R.; Kusano, Aaron S.


    Purpose: The aim of this study was to examine the experiences of radiation oncology applicants and to evaluate the prevalence of behaviors that may be in conflict with established ethical standards. Methods and Materials: An anonymous survey was sent to all 2013 applicants to a single domestic radiation oncology residency program through the National Resident Matching Program (NRMP). Questions included demographics, survey of observed behaviors, and opinions regarding the interview and matching process. Descriptive statistics were presented. Characteristics and experiences of respondents who matched were compared with those who did not match. Results: Questionnaires were returned by 87 of 171 applicants for a 51% response rate. Eighty-two questionnaires were complete and included for analysis. Seventy-eight respondents (95.1%) reported being asked at least 1 question in conflict with the NRMP code of conduct. When asked where else they were interviewing, 64% stated that this query made them uncomfortable. Forty-five respondents (54.9%) reported unsolicited post-interview contact by programs, and 31 (37.8%) felt pressured to give assurances. Fifteen respondents (18.3%) reported being told their rank position or that they were “ranked to match” prior to Match day, with 27% of those individuals indicating this information influenced how they ranked programs. Half of respondents felt applicants often made dishonest or misleading assurances, one-third reported that they believed their desired match outcome could be improved by deliberately misleading programs, and more than two-thirds felt their rank position could be improved by having faculty from their home institutions directly contact programs on their behalf. Conclusions: Radiation oncology applicants report a high prevalence of behaviors in conflict with written NRMP policies. Post-interview communication should be discouraged in order to enhance fairness and support the professional development of future

  12. Impact of a Physician-in-Triage Process on Resident Education

    Directory of Open Access Journals (Sweden)

    Bret A. Nicks


    Full Text Available Introduction: Emergency department (ED crowding negatively impacts patient care quality and efficiency. To reduce crowding many EDs use a physician-in-triage (PIT process. However, few studies have evaluated the effect of a PIT processes on resident education. Our objective was to determine the impact of a PIT process implementation on resident education within the ED of an academic medical center. Methods: We performed a prospective cross-sectional study for a 10-week period from March to June 2011, during operationally historic trended peak patient volume and arrival periods. Emergency medicine residents (three-year program and faculty, blinded to the research objectives, were asked to evaluate the educational quality of each shift using a 5-point Likert scale. Residents and faculty also completed a questionnaire at the end of the study period assessing the perceived impact of the PIT process on resident education, patient care, satisfaction, and throughput. We compared resident and attending data using Mann-Whitney U tests. Results: During the study period, 54 residents and attendings worked clinically during the PIT process with 78% completing questionnaires related to the study. Attendings and residents indicated “no impact” of the PIT process on resident education [median Likert score of 3.0, inter-quartile range (IQR: 2-4]. There was no difference in attending and resident perceptions (p-value =0.18. Both groups perceived patient satisfaction to be “positively impacted” [4.0, IQR:2-4 for attendings vs 4.0,IQR:1-5 for residents, p-value =0.75]. Residents perceived more improvement in patient throughput to than attendings [3.5, IQR:3-4 for attendings vs 4.0, IQR:3-5 for residents, p-value =0.006]. Perceived impact on differential diagnosis generation was negative in both groups [2.0, IQR:1-3 vs 2.5, IQR:1-5, p-value = 0.42].

    Ponce, Brent A; Determann, Jason R; Boohaker, Hikel A; Sheppard, Evan; McGwin, Gerald; Theiss, Steven


    To determine the frequency of social networking, the degree of information publicly disclosed, and whether unprofessional content was identified in applicants from the 2010 Residency Match. Medical professionalism is an essential competency for physicians to learn, and information found on social networking sites may be hazardous to the doctor-patient relationship and an institution's public perception. No study has analyzed the social network content of applicants applying for residency. Online review of social networking Facebook profiles of graduating medical students applying for a residency in orthopedic surgery. Evidence of unprofessional content was based upon Accreditation Council for Graduate Medical Education guidelines. Additional recorded applicant data included as follows: age, United States Medical Licensing Examination part I score, and residency composite score. Relationship between professionalism score and recorded data points was evaluated using an analysis of variance. Nearly half of all applicants, 46% (200/431), had a Facebook profile. The majority of profiles (85%) did not restrict online access to their profile. Unprofessional content was identified in 16% of resident applicant profiles. Variables associated with lower professionalism scores included unmarried relationship status and lower residency composite scores. It is critical for healthcare professionals to recognize both the benefits and risks present with electronic communication and to vigorously protect the content of material allowed to be publically accessed through the Internet.

  14. The Cost of Getting Into Orthopedic Residency: Analysis of Applicant Demographics, Expenditures, and the Value of Away Rotations. (United States)

    Camp, Christopher L; Sousa, Paul L; Hanssen, Arlen D; Karam, Matthew D; Haidukewych, George J; Oakes, Daniel A; Turner, Norman S


    Little is known about the demographics and expenditures of applicants attempting to match into the competitive field of orthopedic surgery. In attempt to better inform potential applicants, the purposes of this work are to (1) better understand the demographics of successfully matched applicants, (2) determine the monetary cost of applying, and (3) assess the value of away rotations for improving chances of a successful match. Prospective comparative survey. Mayo Clinic Department of Orthopedic Surgery, Rochester, MN. A week following the 2015 Orthopedic Surgery Residency Match, a survey was sent to 1,091. The survey focused on applicant demographics, number of programs applied to, cost of applying, and the value of away rotations. A total of 408 applicants completed the survey (response rate = 37%). Of these, 312 (76%) matched and 96 (24%) did not match into a US Orthopedic Surgery Residency. Of the matched applicants, 300 (96%) were from US allopathic medical schools, 9 (3%) US Osteopathic Schools, and 3 (1%) were international graduates. Males comprised 84% of these applicants whereas 16% were female. The mean number of programs applied to was 71 (range: 20-140). On average, applicants were offered 16 interviews (range: 1-53) and they attended 11 (range: 0-12). Completing a rotation at a program increased an applicant׳s chances of matching into that program by a factor of 1.5 (60% vs 40%). Of the applicants who matched, most applicants matched to an orthopedic residency in the same region where the applicant attended medical school (58%). The average cost of the application was $1,664 (range: $100-$5,000) whereas the cost of interviews (travel, food, etc.) was $3,656 (range: $15-$20,000). Total expenditures ranged from $450 to $25,000 (mean = $5,415). Over 8% of matched applicants spent >$10,000. Gaining acceptance into orthopedic surgery residency remains a very competitive process. Away rotations appear to correlate strongly with match status; however, the

  15. The learning styles of orthopedic residents, faculty, and applicants at an academic program. (United States)

    Richard, Raveesh Daniel; Deegan, Brian Francis; Klena, Joel Christian


    To train surgeons effectively, it is important to understand how they are learning. The Kolb Learning Style Inventory (LSI) is based on the theory of experiential learning, which divides the learning cycle into 4 stages: active experimentation (AE), abstract conceptualization (AC), concrete experience, and reflective observation. The purpose of this investigation was to assess the learning styles of orthopedic residents, faculty, and applicants at an east-coast residency program. A total of 90 Kolb LSI, Version 3.1 surveys, and demographic questionnaires were distributed to all residency applicants, residents, and faculty at an academic program. Data collected included age, sex, type of medical school (MD or DO), foreign medical graduate status, and either year since college graduation, postgraduate year level (residents only), or years since completion of residency (faculty only). Seventy-one completed Kolb LSI surveys (14 residents, 14 faculty members, and 43 applicants) were recorded and analyzed for statistical significance. The most prevalent learning style among all participants was converging (53.5%), followed by accommodating (18.3%), diverging (18.3%), and assimilating (9.9%) (p = 0.13). The applicant and resident groups demonstrated a high tendency toward AE followed by AC. The faculty group demonstrated a high tendency toward AC followed by AE. None of the 24 subjects who were 26 years or under had assimilating learning styles, in significant contrast to the 12% of 27- to 30-year-olds and 18% of 31 and older group (p learning style involves problem solving and decision making, with the practical application of ideas and the use of hypothetical-deductive reasoning. Learning through AE decreased with age, whereas learning through AC increased. Copyright © 2014 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

  16. Representation in the Care Planning Process for Nursing Home Residents With Dementia. (United States)

    McCreedy, Ellen; Loomer, Lacey; Palmer, Jennifer A; Mitchell, Susan L; Volandes, Angelo; Mor, Vincent


    Federally mandated assessments of nursing home (NH) residents drive individualized care planning. Residents with cognitive impairment may not be able to meaningfully communicate their care needs and preferences during this process-a gap that may be partially addressed by involving surrogates. We describe the prevalence of family participation in the care planning process for long-stay NH residents with varying degrees of cognitive impairment. Retrospective study using administrative data made available as part of an ongoing pragmatic cluster randomized controlled trial. A total of 292 NHs from 1 large for-profit NH system. Long-stay NH residents in 2016. We identified all care planning assessments conducted in 2016 for long-stay NH residents. Cognitive functioning was defined using the Cognitive Function Scale. The Minimum Data Set was used to determine whether a resident, family member, and/or legal guardian participated in the assessment process. Certification and Survey Provider Enhance Reporting system data was used to identify facility-level correlates of family participation. Bivariate and multivariable hierarchical regression results are presented. The analytic sample included 18,552 long-stay NH residents. Family member/representative participation varied by degree of resident cognitive impairment; 8% of residents with no cognitive impairment had family or representative participation in care planning during 2016, compared with 26% of residents with severe impairment. NHs with more social workers had greater family participation in care planning. Available NH characteristics do not explain most of the variation in family participation between NHs (residual intraclass correlation = .57). Only a minority of family members and surrogates participate in NH care planning, even for residents with severe cognitive impairment. The association between social work staffing and participation suggests family involvement may be a measure of quality improvement

  17. What Makes a Plastic Surgery Residency Program Attractive? An Applicant's Perspective. (United States)

    Atashroo, David A; Luan, Anna; Vyas, Krishna S; Zielins, Elizabeth R; Maan, Zeshaan; Duscher, Dominik; Walmsley, Graham G; Lynch, Michael P; Davenport, Daniel L; Wan, Derrick C; Longaker, Michael T; Vasconez, Henry C


    Plastic surgery is among the most competitive specialties in medicine, but little is known about the attributes of programs that are most attractive to successful applicants. This study aimed to understand and provide insights regarding program characteristics that are most influential to students when ranking plastic surgery programs. An anonymous online survey was conducted with newly matched plastic surgery residents for the integrated and combined Match in 2012 and 2013. Subjects were queried regarding their demographics, qualifications, application experiences, and motivations for residency program selection. A total of 92 of 245 matched plastic surgery residents (38 percent) responded to the survey. The perception of resident happiness was the most positive factor influencing program ranking, followed by high operative volume, faculty mentorship, and strong research infrastructure. Perception of a program as "malignant" was the most negative attribute. Applicants with Step 1 scores greater than 245 received significantly more interviews (p =0.001) and considered resident benefits less important (p Plastic surgery applicants have differing preferences regarding the ideal training program, but some attributes resonate. These trends can guide programs for improvement in attracting the best applicants.

  18. Orion: a web-based application designed to monitor resident and fellow performance on-call. (United States)

    Itri, Jason N; Kim, Woojin; Scanlon, Mary H


    Radiology residency and fellowship training provides a unique opportunity to evaluate trainee performance and determine the impact of various educational interventions. We have developed a simple software application (Orion) using open-source tools to facilitate the identification and monitoring of resident and fellow discrepancies in on-call preliminary reports. Over a 6-month period, 19,200 on-call studies were interpreted by 20 radiology residents, and 13,953 on-call studies were interpreted by 25 board-certified radiology fellows representing eight subspecialties. Using standard review macros during faculty interpretation, each of these reports was classified as "agreement", "minor discrepancy", and "major discrepancy" based on the potential to impact patient management or outcome. Major discrepancy rates were used to establish benchmarks for resident and fellow performance by year of training, modality, and subspecialty, and to identify residents and fellows demonstrating a significantly higher major discrepancy rate compared with their classmates. Trends in discrepancies were used to identify subspecialty-specific areas of increased major discrepancy rates in an effort to tailor the didactic and case-based curriculum. A series of missed-case conferences were developed based on trends in discrepancies, and the impact of these conferences is currently being evaluated. Orion is a powerful information technology tool that can be used by residency program directors, fellowship programs directors, residents, and fellows to improve radiology education and training.

  19. Reviving Markov processes and applications

    International Nuclear Information System (INIS)

    Cai, H.


    In this dissertation we study a procedure which restarts a Markov process when the process is killed by some arbitrary multiplicative functional. The regenerative nature of this revival procedure is characterized through a Markov renewal equation. An interesting duality between the revival procedure and the classical killing operation is found. Under the condition that the multiplicative functional possesses an intensity, the generators of the revival process can be written down explicitly. An intimate connection is also found between the perturbation of the sample path of a Markov process and the perturbation of a generator (in Kato's sense). The applications of the theory include the study of the processes like piecewise-deterministic Markov process, virtual waiting time process and the first entrance decomposition (taboo probability)

  20. Away Rotations and Matching in Integrated Plastic Surgery Residency: Applicant and Program Director Perspectives. (United States)

    Drolet, Brian C; Brower, Jonathan P; Lifchez, Scott D; Janis, Jeffrey E; Liu, Paul Y


    Although nearly all medical students pursuing integrated plastic surgery residency participate in elective rotations away from their home medical school, the value and costs of these "away" rotations have not been well studied. The authors surveyed all integrated plastic surgery program directors and all applicants in the 2015 National Residency Matching Program. Forty-two program directors and 149 applicants (64 percent and 70 percent response rate, respectively) completed the survey. Applicants reported 13.7 weeks spent on plastic surgery rotations during medical school, including a mean of 9.2 weeks on away rotations. Average reported cost for away rotations was $3591 per applicant. Both applicants and program directors most commonly reported "making a good impression" (44.6 percent and 36.6 percent, respectively) or finding a "good-fit" program (27.7 percent and 48.8 percent, respectively) as the primary goal for away rotations. Almost all applicants (91.1 percent) believed an away rotation made them more competitive for matching to a program at which they rotated. Program directors ranked a strong away rotation performance as the most important residency selection criterion. Twenty-seven percent of postgraduate year-1 positions were filled by an away rotatorm and an additional 17 percent were filled by a home medical student. Away rotations appear to be mutually beneficial for applicants and programs in helping to establish a good fit between students and training programs through an extended interaction with the students, residents, and faculty. In addition, making a good impression on a senior elective rotation (home or away) may improve an applicant's chance of matching to a residency program.

  3. Business process improvement: an electronic system to monitor compliance with medical resident work hours. (United States)

    Landesman, Linda Young; Markowitz, Forest; Conde, Nelson


    The limitation of medical intern and resident work hours, known as the Bell 405 regulations, was initiated in New York State in 1989 with a modification to the state hospital code. The Bell 405 regulations were strengthened in 2000, and facilities would now be fined for noncompliance. Monitoring systems in place at that time were insufficient to provide an adequate level of review for the New York City Health and Hospitals Corporation (HHC) with more than 7,000 medical residents whose training is based at or who rotate through these public hospitals. A "simple to use," yet comprehensive, method of monitoring compliance needed to be developed to ensure that residents and interns complied with laws regulating working hours. The subsequent development of national accreditation standards increased the stakes for reliable scrutiny. HHC developed and implemented a Web-based Structured Query Language (SQL) application that facilitated easy access to work hour surveys captured through electronic time sheets. The time sheet data automatically entered a database that provided instant analysis of conformance to state law. The development of an electronic on-line application accessible from anywhere allowed HHC to efficiently identify nonconformance and pinpoint corrective action. Since the inception of the application and its expansion allowing access through the intranet, 26,000 individual time sheets have been submitted for evaluation. With the national movement regulating work hours, other hospitals still at the pencil and manual computation stage would greatly benefit by developing a similar application.

  4. Differential factors that influence applicant selection of a prosthodontic residency program. (United States)

    Blissett, Ryan; Lee, Meng-Chieh; Jimenez, Monik; Sukotjo, Cortino


    The main objectives of this study were to identify current prosthodontic resident demographics and to analyze factors that may influence applicants in selecting prosthodontics as a career, as well as a specific prosthodontic program. We also investigated the influence of age, gender, relationship status, and year in program on applicant decisions. Two questionnaires were mailed to all prosthodontic residents (N = 304) registered with the American College of Prosthodontists (ACP) Central Office. Part I assessed resident demographics and factors influencing choice of specialty. Part II assessed factors influencing the selection of a specific prosthodontic program. Completed surveys were obtained from 193 of 304 (63.4%) of all prosthodontic residents registered at the ACP Central Office. The completed surveys represented approximately 48% of the total population of prosthodontic residents in the United States. Demographic data revealed that 37% and 62% of the respondents were female and male, respectively (1% did not report gender). The mean age of the respondents was 30.3 years. More residents reported being married than either single or in a relationship. Most residents were accepted to their top choice program. Part I of the survey revealed that the complexity and challenge of treatment planning/treatment, ability to lead multidisciplinary cases, possession of skills/talents suited to the specialty, enjoyment of clinical work, and the intellectual content of the specialty were reported to be the five most influential factors in choosing prosthodontics as a career. Part II demonstrated that applicants place a high emphasis on clinical education, their impression of the program director, advice from predoctoral mentors, their impression of resident satisfaction and happiness, and the opportunity to place dental implants. The factors of least importance are climate and opportunities to moonlight, teach, and conduct research. Dental students consider the complexity and

  5. The Academic Support Process (ASP) website: helping preceptors develop resident learning plans and track progress. (United States)

    Stodel, Emma J; Montpetit, Madeleine; Eyre, Alison; Prentice, Michelle; Johnston, Mary


    At times, preceptors struggle with aspects of resident education. Many are looking for more support and faculty development in this area. To address preceptors' needs for resources and provide a proactive framework for their teaching, the Academic Support Process (ASP) website was developed and evaluated. Preceptors' (N = 35) experiences using the ASP website, as well as their perceptions of its usefulness in supporting resident education, were identified. The research comprised two phases: a self-directed workshop involving the creation of a web-based learning plan for a standardised scenario of a resident in difficulty followed by 3 months use of the ASP website with residents in their practice. Information on their experiences was solicited via surveys and focus group interviews. Findings revealed the ASP website enabled preceptors to find words for their concerns around resident competency, gave them a proactive teaching framework, expanded their arsenal of teaching strategies, and supported a customised approach for all learners along the performance spectrum. However, there were a number of challenges encountered by the preceptors that affected site use and buy in. Results are promising. Next steps involve developing a clear strategy for adoption.

  6. Assessment of resident and fellow knowledge of the organ donor referral process (United States)

    Passarella, Ralph J.; Salter, Megan L.; Kucirka, Lauren M.; Orandi, Babak J.; Law, Andrew H.; Segev, Dorry L.


    Maximizing deceased donation rates can decrease the organ shortage. Non-transplant physicians play a critical role in facilitating conversion of potential deceased donors to actual donors, but studies suggest that physicians lack knowledge about the organ donation process. Since residency and fellowship are often the last opportunities for formal medical training, we hypothesized that deficiencies in knowledge might originate in residency and fellowship. We conducted a cross-sectional survey to assess knowledge about organ donation, experience in donor conversion, and opinions of the process among residents and fellows after their intensive care unit rotations at the Johns Hopkins Hospital. Of 40 participants, 50% had previously facilitated donor conversion, 25% were familiar with the guidelines of the Organ Procurement Organization (OPO), and 10% had received formal instruction from the OPO. The median score on the knowledge assessment was 5 out of 10; higher knowledge score was not associated with level of medical training, prior training in or experience with donor conversion, or with favorable opinions about the OPO. We identified a pervasive deficit in knowledge among residents and fellows at an academic medical center with an active transplant program that may help explain attending-level deficits in knowledge about the organ donation process.

  7. A Process-Oriented Approach to Teaching Religion and Spirituality in Psychiatry Residency Training. (United States)

    Awaad, Rania; Ali, Sara; Salvador, Melina; Bandstra, Belinda


    Although the importance of addressing issues of spirituality and religion is increasingly acknowledged within psychiatry training, many questions remain about how to best teach relevant knowledge, skills, and attitudes. Current literature on curricula highlights the importance of maintaining a clinical focus and the balance between didactic content and process issues. The authors present findings from a program evaluation study of a course on religion, spirituality, and psychiatry that deliberately takes a primarily process-oriented, clinically focused approach. Two six-session courses were offered. The first course targeted fourth-year psychiatry residents and the second targeted third-year psychiatry residents. Teaching sessions consisted of brief didactics combined with extensive process-oriented discussion. A two-person faculty team facilitated the courses. Clinical case discussions were integrated throughout the curriculum. A panel of chaplains was invited to participate in one session of each course to discuss the interface between spiritual counsel and psychiatry. A modified version of the Course Impact Questionnaire, a 20-item Likert scale utilized in previous studies of spirituality curricula in psychiatry, assessed residents' personal spiritual attitudes, competency, change in professional practice, and change in professional attitudes before and after the course (N = 20). Qualitative feedback was also elicited through written comments. The results from this study showed a statistically significant difference between the pre- and post-test scale for residents' self-perceived competency and change in professional practice. The findings suggest improvement in competency and professional practice scores in residents who participated in this course. This points toward the overall usefulness of the course and suggests that a process-oriented approach may be effective for discussing religion and spirituality in psychiatric training.

  9. Selection criteria for internal medicine residency applicants and professionalism ratings during internship. (United States)

    Cullen, Michael W; Reed, Darcy A; Halvorsen, Andrew J; Wittich, Christopher M; Kreuziger, Lisa M Baumann; Keddis, Mira T; McDonald, Furman S; Beckman, Thomas J


    To determine whether standardized admissions data in residents' Electronic Residency Application Service (ERAS) submissions were associated with multisource assessments of professionalism during internship. ERAS applications for all internal medicine interns (N=191) at Mayo Clinic entering training between July 1, 2005, and July 1, 2008, were reviewed by 6 raters. Extracted data included United States Medical Licensing Examination scores, medicine clerkship grades, class rank, Alpha Omega Alpha membership, advanced degrees, awards, volunteer activities, research experiences, first author publications, career choice, and red flags in performance evaluations. Medical school reputation was quantified using U.S. News & World Report rankings. Strength of comparative statements in recommendation letters (0 = no comparative statement, 1 = equal to peers, 2 = top 20%, 3 = top 10% or "best") were also recorded. Validated multisource professionalism scores (5-point scales) were obtained for each intern. Associations between application variables and professionalism scores were examined using linear regression. The mean ± SD (minimum-maximum) professionalism score was 4.09 ± 0.31 (2.13-4.56). In multivariate analysis, professionalism scores were positively associated with mean strength of comparative statements in recommendation letters (β = 0.13; P = .002). No other associations between ERAS application variables and professionalism scores were found. Comparative statements in recommendation letters for internal medicine residency applicants were associated with professionalism scores during internship. Other variables traditionally examined when selecting residents were not associated with professionalism. These findings suggest that faculty physicians' direct observations, as reflected in letters of recommendation, are useful indicators of what constitutes a best student. Residency selection committees should scrutinize applicants' letters for strongly favorable

  11. Personality types of otolaryngology resident applicants as described by the Myers-Briggs Type Indicator. (United States)

    Zardouz, Shawn; German, Michael A; Wu, Edward C; Djalilian, Hamid R


    To assess the personality types of applicants to a single otolaryngology residency program using the Myers- Briggs Type Indicator. The personality types were compared with those of the general population and with physicians in other medical specialties. Cross-sectional survey. University hospital. A personality survey was emailed to 327 resident physician applicants over 2 consecutive years (2008- 2009). Analysis was accomplished by calculating prevalence estimates. Of the 327 anonymous surveys, 137 were completed (response rate = 42%). The Introverted/Sensing/Thinking/ Judging personality type was the most prevalent (14.6%), representing 13% of the general population. Prospective applicants displayed mostly Extroverted (E; 58%), Sensing (S; 54%), Thinking (T; 62%), and Judging (J; 61%) personality traits. Of the 16 personality types, statistically significant differences were found between otolaryngology resident applicants and the general population only for the Extroverted/Sensing/Thinking/ Perceiving (P = .002) personality type after correcting for multiple comparisons. The Intuitive (N; 46%) and Feeling (F; 38%) types correlated closely with the reported personality types of those individuals in non–primary care specialties, 47% and 28%, respectively. Extroverted (E) and Thinking (T) individuals appeared to prefer surgical specialties, which occurred in 58% and 62% of the applicants, respectively. There were no significant differences between male and female applicants. This study examines the personality types of medical students applying to an otolaryngology residency. The results support a highly structured, data-driven teaching preference among applicants. These results may allow for a better understanding of the personalities of medical students who are interested in otolaryngology.

    Current selection methods for neurosurgical residents fail to include objective measurements of bimanual psychomotor performance. Advancements in computer-based simulation provide opportunities to assess cognitive and psychomotor skills in surgically naive populations during complex simulated neurosurgical tasks in risk-free environments. This pilot study was designed to answer 3 questions: (1) What are the differences in bimanual psychomotor performance among neurosurgical residency applicants using NeuroTouch? (2) Are there exceptionally skilled medical students in the applicant cohort? and (3) Is there an influence of previous surgical exposure on surgical performance? Participants were instructed to remove 3 simulated brain tumors with identical visual appearance, stiffness, and random bleeding points. Validated tier 1, tier 2, and advanced tier 2 metrics were used to assess bimanual psychomotor performance. Demographic data included weeks of neurosurgical elective and prior operative exposure. This pilot study was carried out at the McGill Neurosurgical Simulation Research and Training Center immediately following neurosurgical residency interviews at McGill University, Montreal, Canada. All 17 medical students interviewed were asked to participate, of which 16 agreed. Performances were clustered in definable top, middle, and bottom groups with significant differences for all metrics. Increased time spent playing music, increased applicant self-evaluated technical skills, high self-ratings of confidence, and increased skin closures statistically influenced performance on univariate analysis. A trend for both self-rated increased operating room confidence and increased weeks of neurosurgical exposure to increased blood loss was seen in multivariate analysis. Simulation technology identifies neurosurgical residency applicants with differing levels of technical ability. These results provide information for studies being developed for longitudinal studies on the

  14. Coastal Processes with Engineering Applications (United States)

    Dean, Robert G.; Dalrymple, Robert A.


    The world's coastlines, dividing land from sea, are geological environments that are unique in their composition and the physical processes affecting them. At the dynamically active intersection of land and the oceans, humans have been building structures throughout history. Initially used for naval and commercial purposes, more recently recreation and tourism have increased activity in the coastal zone dramatically. Shoreline development is now causing a significant conflict with natural coastal processes. This text on coastal engineering will help the reader understand these coastal processes and develop strategies to cope effectively with shoreline erosion. The book is organized in four parts: (1) an overview of coastal engineering, using case studies to illustrate problems; (2) hydrodynamics of the coastal zone, reviewing storm surges, water waves, and low frequency motions within the nearshore and surf zone; (3) coastal responses including equilibrium beach profiles and sediment transport; (4) applications such as erosion mitigation, beach nourishment, coastal armoring, tidal inlets, and shoreline management.

  15. Integrated Plastic Surgery Residency Applicant Trends and Comparison With Other Surgical Specialties. (United States)

    Abraham, Jasson T; Nguyen, Anson V; Weber, Robert A


    There has been a relatively rapid increase in the number and size of "integrated" residency programs in plastic surgery (PS) over the past decade. The objective of this study is to evaluate trends of US senior applicants of PS compared with other surgical specialties from 2007 to 2016. Data were obtained from "NRMP: Main Residency Match" and from "NRMP: Charting Outcomes in the Match." Frequencies, percentages, and proportions were calculated for categorical variables. Odds ratios with 95% confidence interval were calculated to evaluate the relationship of Alpha Omega Alpha membership and match success. The overall National Resident Matching Program match rate ranged from 93.1% to 95.1%, but rates were lower for surgical specialties, ranging from 74.7% to 86.6% in 2016. From 2008 to 2016, PS had a relatively high growth rate in the number of positions (65.2%) from 2008 to 2016. Matched PS and Otolaryngology applicants routinely had the highest mean United States Medical Licensing Examination Step 1 and Step 2 Clinical Knowledge scores. Alpha Omega Alpha membership has a significant impact on successfully matching into a surgical specialty (P < 0.1). Matched applicants of surgical subspecialties (PS, Otolaryngology, orthopedics, and neurosurgery) had similar mean number of research, work, and volunteer experiences. However, PS and neurosurgery matched applicants had notably higher mean research productivity. The rapid increase in the number of positions in PS residency training has not resulted in a decrease in caliber of matched applicants, even though match rates have dramatically increased. Currently, PS continues to attract and successfully match highly qualified applicants, but other surgical specialties have increasingly similar board scores and mean number of extracurricular experiences.

  16. Effect of Process Changes in Surgical Training on Quantitative Outcomes From Surgery Residency Programs. (United States)

    Dietl, Charles A; Russell, John C


    The purpose of this article is to review the literature on process changes in surgical training programs and to evaluate their effect on the Accreditation Council of Graduate Medical Education (ACGME) Core Competencies, American Board of Surgery In-Training Examination (ABSITE) scores, and American Board of Surgery (ABS) certification. A literature search was obtained from MEDLINE via,, Google Scholar on all peer-reviewed studies published since 2003 using the following search queries: surgery residency training, surgical education, competency-based surgical education, ACGME core competencies, ABSITE scores, and ABS pass rate. Our initial search list included 990 articles on surgery residency training models, 539 on competency-based surgical education, 78 on ABSITE scores, and 33 on ABS pass rate. Overall, 31 articles met inclusion criteria based on their effect on ACGME Core Competencies, ABSITE scores, and ABS certification. Systematic review showed that 5/31, 19/31, and 6/31 articles on process changes in surgical training programs had a positive effect on patient care, medical knowledge, and ABSITE scores, respectively. ABS certification was not analyzed. The other ACGME core competencies were addressed in only 6 studies. Several publications on process changes in surgical training programs have shown a positive effect on patient care, medical knowledge, and ABSITE scores. However, the effect on ABS certification, and other quantitative outcomes from residency programs, have not been addressed. Studies on education strategies showing evidence that residency program objectives are being achieved are still needed. This article addresses the 6 ACGME Core Competencies.

  17. Self-Reported Emergency Medicine Residency Applicant Attitudes Towards a Procedural Cadaver Laboratory Curriculum

    Directory of Open Access Journals (Sweden)

    Hoffman, Lance


    Full Text Available OBJECTIVE: Residency applicants consider a variety of factors when ranking emergency medicine (EM programs for their NRMP match list. A human cadaver emergency procedure lab curriculum is uncommon. We hypothesized that the presence this curriculum would positively impact the ranking of an EM residency program.METHODS: The EM residency at Nebraska Medical Center is an urban, university-based program with a PGY I-III format. Residency applicants during the interview for a position in the PGY I class of 2006 were surveyed by three weekly electronic mailings. The survey was distributed in March 2006 after the final NRMP match results were released. The survey explored learner preferences and methodological commonality of models of emergency procedural training, as well as the impact of a procedural cadaver lab curriculum on residency ranking. ANOVA of ranks was used to compare responses to ranking questions.RESULTS: Of the 73 potential subjects, 54 (74% completed the survey. Respondents ranked methods of procedural instruction from 1 (most preferred or most common technique to 4 (least preferred or least common technique. Response averages and 95% confidence intervals for the preferred means of learning a new procedure are as follows: textbook (3.69; 3.51-3.87, mannequin (2.83; 2.64-3.02, human cadaver (1.93; 1.72-2.14, and living patient (1.56; 1.33-1.79. Response averages for the commonality of means used to teach a new procedure are as follows: human cadaver (3.63; 3.46-3.80, mannequin (2.70; 2.50-2.90, living patient (2.09; 1.85-2.33, and textbook (1.57; 1.32-1.82. When asked if the University of Nebraska Medical Center residency ranked higher in the individual's match list because of its procedural cadaver lab, 14.8% strongly disagreed, 14.8% disagreed, 40.7% were neutral, 14.8% agreed, and 14.8% strongly agreed.CONCLUSION: We conclude that, although cadaveric procedural training is viewed by senior medical student learners as a desirable means

  18. Strategic Application of Residence-Time Control in Continuous-Flow Reactors (United States)

    Mándity, István M; Ötvös, Sándor B; Fülöp, Ferenc


    As a sustainable alternative for conventional batch-based synthetic techniques, the concept of continuous-flow processing has emerged in the synthesis of fine chemicals. Systematic tuning of the residence time, a key parameter of continuous-reaction technology, can govern the outcome of a chemical reaction by determining the reaction rate and the conversion and by influencing the product selectivity. This review furnishes a brief insight into flow reactions in which high chemo- and/or stereoselectivity can be attained by strategic residence-time control and illustrates the importance of the residence time as a crucial parameter in sustainable method development. Such a fine reaction control cannot be performed in conventional batch reaction set-ups. PMID:26246983

  19. Discrete stochastic processes and applications

    CERN Document Server

    Collet, Jean-François


    This unique text for beginning graduate students gives a self-contained introduction to the mathematical properties of stochastics and presents their applications to Markov processes, coding theory, population dynamics, and search engine design. The book is ideal for a newly designed course in an introduction to probability and information theory. Prerequisites include working knowledge of linear algebra, calculus, and probability theory. The first part of the text focuses on the rigorous theory of Markov processes on countable spaces (Markov chains) and provides the basis to developing solid probabilistic intuition without the need for a course in measure theory. The approach taken is gradual beginning with the case of discrete time and moving on to that of continuous time. The second part of this text is more applied; its core introduces various uses of convexity in probability and presents a nice treatment of entropy.

  20. Does residence time affect responses of alien species richness to environmental and spatial processes?

    Directory of Open Access Journals (Sweden)

    Matteo Dainese


    Full Text Available One of the most robust emerging generalisations in invasion biology is that the probability of invasion increases with the time since introduction (residence time. We analysed the spatial distribution of alien vascular plant species in a region of north-eastern Italy to understand the influence of residence time on patterns of alien species richness. Neophytes were grouped according to three periods of arrival in the study region (1500–1800, 1800–1900, and > 1900. We applied multiple regression (spatial and non-spatial with hierarchical partitioning to determine the influence of climate and human pressure on species richness within the groups. We also applied variation partitioning to evaluate the relative importance of environmental and spatial processes. Temperature mainly influenced groups with speciesa longer residence time, while human pressure influenced the more recently introduced species, although its influence remained significant in all groups. Partial regression analyses showed that most of the variation explained by the models is attributable to spatially structured environmental variation, while environment and space had small independent effects. However, effects independent of environment decreased, and spatially independent effects increased, from older to the more recent neophytes. Our data illustrate that the distribution of alien species richness for species that arrived recently is related to propagule pressure, availability of novel niches created by human activity, and neutral-based (dispersal limitation processes, while climate filtering plays a key role in the distribution of species that arrived earlier. This study highlights the importance of residence time, spatial structure, and environmental conditions in the patterns of alien species richness and for a better understanding of its geographical variation.

  1. The hand surgery fellowship application process: expectations, logistics, and costs. (United States)

    Meals, Clifton; Osterman, Meredith


    To investigate expectations, logistics, and costs relevant to the hand surgery fellowship application process. We sought to discover (1) what both applicants and program directors are seeking, (2) what both parties have to offer, (3) how both parties collect information about each other, and (4) the costs incurred in arranging each match. We conducted on-line surveys of hand surgery fellowship applicants for appointment in 2015 and of current fellowship program directors. Sixty-two applicants and 41 program directors completed the survey. Results revealed applicants' demographic characteristics, qualifications, method of ranking hand fellowship programs, costs incurred (both monetary and opportunity) during the application process, ultimate match status, and suggestions for change. Results also revealed program directors' program demographics, rationale for offering interviews and favorably ranking applicants, application-related logistical details, costs incurred (both monetary and opportunity) during the application process, and suggestions for change. Applicants for hand surgery fellowship training are primarily interested in a potential program's academic reputation, emphasis on orthopedic surgery, and location. The typical, successfully matched applicant was a 30-year-old male orthopedic resident with 3 publications to his credit. Applicants rely on peers and Web sites for information about fellowships. Fellowship directors are primarily seeking applicants recommended by other experienced surgeons and with positive personality traits. The typical fellowship director offers a single year of orthopedic-based fellowship training to 2 fellows per year and relies on a common application and in-person interviews to collect information about applicants. Applicants appear to be more concerned than directors about the current state of the match process. Applicants and directors alike incur heavy costs, in both dollars and opportunity, to arrange each match. A nuanced

  2. Exploring residents' communication learning process in the workplace: a five-phase model.

    Full Text Available Competency-based education is a resurgent paradigm in professional medical education. However, more specific knowledge is needed about the learning process of such competencies, since they consist of complex skills. We chose to focus on the competency of skilled communication and want to further explore its learning process, since it is regarded as a main competency in medical education.This study aims to explore in more detail the learning process that residents in general practice go through during workplace-based learning in order to become skilled communicators.A qualitative study was conducted in which twelve GP residents were observed during their regular consultations, and were interviewed in-depth afterwards.Analysis of the data resulted in the construction of five phases and two overall conditions to describe the development towards becoming a skilled communicator: Confrontation with (undesired behaviour or clinical outcomes was the first phase. Becoming conscious of one's own behaviour and changing the underlying frame of reference formed the second phase. The third phase consisted of the search for alternative behaviour. In the fourth phase, personalization of the alternative behaviour had to occur, this was perceived as difficult and required much time. Finally, the fifth phase concerned full internalization of the new behaviour, which by then had become an integrated part of the residents' clinical repertoire. Safety and cognitive & emotional space were labelled as overall conditions influencing this learning process.Knowledge and awareness of these five phases can be used to adjust medical working and learning environments in such a way that development of skilled medical communication can come to full fruition and its benefits are more fully reaped.

  4. Microsystem for signal processing applications (United States)

    Frankenstein, B.; Froehlich, K.-J.; Hentschel, D.; Reppe, G.


    Acoustic monitoring of technological processes requires methods that eliminate noise as much as possible. Sensor-near signal evaluation can contribute substantially. Frequently, a further necessity exists to integrate the measuring technique in the monitored structure. The solution described contains components for analog preprocessing of acoustic signals, their digitization, algorithms for data reduction, and digital communication. The core component is a digital signal processor (DSP). Digital signal processors perform the algorithms necessary for filtering, down sampling, FFT computation and correlation of spectral components particularly effective. A compact, sensor-near signal processing structure was realized. It meets the Match-X standard, which as specified by the German Association for Mechanical and Plant Engineering (VDMA) for development of micro-technical modules, which can be combined to applicaiton specific systems. The solution is based on AL2O3 ceramic components including different signal processing modules as ADC, as well as memory and power supply. An arbitrary waveform generator has been developed and combined with a power amplifier for piezoelectric transducers in a special module. A further module interfaces to these transducers. It contains a multi-channel preamplifier, some high-pass filters for analog signal processing and an ADC-driver. A Bluetooth communication chip for wireless data transmission and a DiscOnChip module are under construction. As a first application, the combustion behavior of safety-relevant contacts is monitored. A special waveform up to 5MHz is produced and sent to the monitored object. The resulting signal form is evaluated with special algorithms, which extract significant parameters of the signal, and transmitted via CAN-bus.

  5. Robotic vision. [process control applications (United States)

    Williams, D. S.; Wilf, J. M.; Cunningham, R. T.; Eskenazi, R.


    Robotic vision, involving the use of a vision system to control a process, is discussed. Design and selection of active sensors employing radiation of radio waves, sound waves, and laser light, respectively, to light up unobservable features in the scene are considered, as are design and selection of passive sensors, which rely on external sources of illumination. The segmentation technique by which an image is separated into different collections of contiguous picture elements having such common characteristics as color, brightness, or texture is examined, with emphasis on the edge detection technique. The IMFEX (image feature extractor) system performing edge detection and thresholding at 30 frames/sec television frame rates is described. The template matching and discrimination approach to recognize objects are noted. Applications of robotic vision in industry for tasks too monotonous or too dangerous for the workers are mentioned.

  6. Resident resistance. (United States)

    Price, J L; Cleary, B


    Clearly, faculty must work hard with residents to explore the nature of their resistance to a program's learning and growth opportunities. Initial steps to a deeper, more effective, and longer-lasting change process must be pursued. If resident resistance is mishandled or misunderstood, then learning and professional growth may be sidetracked and the purposes of residency training defeated. Listening to the whole person of the resident and avoiding the trap of getting caught up in merely responding to select resident behaviors that irritate us is critical. Every faculty member in the family practice residency program must recognize resistance as a form of defense that cannot immediately be torn down or taken away. Resident defenses have important purposes to play in stress reduction even if they are not always healthy. Residents, especially interns, use resistance to avoid a deeper and more truthful look at themselves as physicians. A family practice residency program that sees whole persons in their residents and that respects resident defenses will effectively manage the stress and disharmony inherent to the resistant resident.

  7. Delivering on the Promise of CLER: A Patient Safety Rotation that Aligns Resident Education with Hospital Processes. (United States)

    Patel, Ekta; Muthusamy, Veena; Young, John Q


    Residency programs must provide training in patient safety. Yet, significant gaps exist among published patient safety curricula. The authors developed a rotation designed to be scalable to an entire residency, built on sound pedagogy, aligned with hospital safety processes, and effective in improving educational outcomes. From July 2015 to May 2017, each second-year resident completed the two-week rotation. Residents learned the foundational science via multiple information modalities and then practiced applying key concepts during a mock root cause analysis. Next, each resident performed a special review of an actual adverse patient event and presented findings to the hospital's Special Review Committee (SRC). Multiple educational outcomes were assessed, including resident satisfaction and attitudes (post-rotation survey), changes in knowledge via pre- and two weeks post-test, quality of the resident's written safety analysis and oral presentation (per survey of SRC members), and organizational changes resulting from residents' reviews. Twenty-two residents completed the rotation. Most components were rated favorably; 80% (12/15 respondents) indicated interest in future patient safety work. Knowledge improved by 44.3% (P presentations as inferior to faculty's. The reviews identified safety vulnerabilities and led to multiple corrective actions. The authors will evaluate the curriculum in a controlled trial with better measures of change in behavior. Further tests of the curriculum's scalability to other contexts are needed.

  8. Supporting autonomy of nursing home residents with dementia in the informed consent process. (United States)

    Beattie, Elizabeth; O'Reilly, Maria; Fetherstonhaugh, Deirdre; McMaster, Mitchell; Moyle, Wendy; Fielding, Elaine


    Background In studies involving people with dementia, researchers have historically defaulted to seeking consent from a proxy, the assumption being that people with dementia are unable to provide their own informed consent. This choice denies people with dementia a voice in the consent process, thus disregarding their autonomy and agency. Recently, other options for improving the consent process have been explored. Objective This study aimed to determine whether nursing home residents with dementia could demonstrate an ability to provide their own informed consent as determined by the Evaluation to Sign Consent instrument. Methods As part of a larger study on the quality of life of nursing home residents, the Evaluation to Sign Consent was administered to 392 people diagnosed with dementia. Data on demographic variables, such as gender and age, as well as level of cognitive impairment, were also collected. Results Just over one-fifth (22%) of the residents with dementia were judged as having the capacity to provide their own informed consent to participate in this specific research project. Consistent with existing literature, capacity to consent was significantly, and negatively, associated with cognitive impairment. Conclusion This study demonstrates that assuming all people diagnosed with dementia are unable to provide informed consent for research on the basis of cognitive test scores, or on clinical assessment alone, potentially denies them the autonomy to make a decision that they may be capable of making. Research involving people with mild-to-moderate dementia needs to consider evaluating whether potential participants have the capacity to provide their own consent.

  11. [Comprehensive Assessment of Psychiatric Residents: An Addition to the Program Admission Process]. (United States)

    Luis, E Jaramillo G; Elena, Martín C


    The training of medical specialists is a long and complex process. Its purpose is to guarantee the society that they are the right professionals to meet the health needs of the population. The first step to ensure this objective is the admission process. In psychiatry this process, monitoring resident students and the criteria for each one are different in each country. Admission in Colombia is a heterogeneous process, not standardized, which varies greatly from one university to another, even between private and public universities. At the National University of Colombia, the admissions process is handled by the Admissions Office and includes: a written test for which you must obtain a minimum score, a resume rating and an interview. The Teaching Committee and the Department of Psychiatry considered the admission procedure in general to be good, but in need of refinement. Due to the experience of some teachers and given the current rules, a "comprehensive assessment" for master and doctoral students was required and in 1996 it was decided that this method of assessment for admission to a specialization in Psychiatry would serve to complement the admission process. The article describes the experience of the process and its outcomes, strengths and weaknesses. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

  12. Visas for Switzerland and France - Time needed to process applications

    CERN Multimedia


    Please note that any person required to be in possession of a visa in order to take up functions at CERN must start the application process sufficiently early to allow the visa to be issued in time.   The submission of an incomplete application, local circumstances and an increase in applications before the summer holiday period can all result in considerable variation in the time needed to process your application and issue the visa. You are therefore recommended to submit your visa application at least three months, and not later than 21 days, prior to your departure date. We would also like to remind you that the Swiss Consulate in Paris and the French Consulate in Geneva can issue visas exclusively to people resident within their respective spheres of competence (i.e. those who are holders of a French or Swiss residence permit respectively). You must therefore obtain all visas required for stays longer than three months in France or Switzerland from the visa-issuing authority competent for ...

  13. Obstetrics and gynaecology residents' knowledge of the informed consent process and its practice in their training institutions. (United States)

    Okonta, P I


    The ethical principle of autonomy as expressed in the practice of informed consent is a core tenet of clinical practice and good patient physician relationship. The aim was to identify specific gaps in the knowledge of trainee obstetricians and gynecologists in Nigeria about the informed consent process and its content. It also sought to describe the practice of informed consent in their respective institutions. A survey of Residents in obstetrics and gynecology attending the revision course of the Faculty of obstetrics and gynecology of the national postgraduate medical college was done to determine their knowledge of the informed consent process and its practice in their institutions. None of the residents was able to give responses that contained all five conditions for informed consent to be valid. Furthermore, only 3 (2.22%) Residents mentioned that the name of the surgeon to perform the surgery should be part of the information provided to patients during the informed consent process. Similarly, only 8 (5.93%) mentioned that consequences of not having the surgery should be part of the informed consent process. The concept of the 'emancipated minor' being competent to give consent was known by 38% of the residents. Although Residents in obstetrics and gynecology in Nigeria have some knowledge of the informed consent process, this knowledge is deficient in key areas such as competence to give consent, content and scope of information to be disclosed to patients for surgery. There is a need to teach residents the rudiments of informed consent and bioethics in general.

  14. Associations between Otolaryngology Applicant Characteristics and Future Performance in Residency or Practice: A Systematic Review. (United States)

    Bowe, Sarah N; Laury, Adrienne M; Gray, Stacey T


    Objective This systematic review aims to evaluate which applicant characteristics available to an otolaryngology selection committee are associated with future performance in residency or practice. Data Sources PubMed, Scopus, ERIC, Health Business, Psychology and Behavioral Sciences Collection, and SocINDEX. Review Methods Study eligibility was performed by 2 independent investigators in accordance with the PRISMA protocol (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Data obtained from each article included research questions, study design, predictors, outcomes, statistical analysis, and results/findings. Study bias was assessed with the Quality in Prognosis Studies tool. Results The initial search identified 439 abstracts. Six articles fulfilled all inclusion and exclusion criteria. All studies were retrospective cohort studies (level 4). Overall, the studies yielded relatively few criteria that correlated with residency success, with generally conflicting results. Most studies were found to have a high risk of bias. Conclusion Previous resident selection research has lacked a theoretical background, thus predisposing this work to inconsistent results and high risk of bias. The included studies provide historical insight into the predictors and criteria (eg, outcomes) previously deemed pertinent by the otolaryngology field. Additional research is needed, possibly integrating aspects of personnel selection, to engage in an evidence-based approach to identify highly qualified candidates who will succeed as future otolaryngologists.

  15. Recent trends in applicants and the matching process for the integrated plastic surgery match. (United States)

    Super, Nikki; Tieman, Joshua; Boucher, Kenneth; Rockwell, William Bradford; Agarwal, Jayant P


    Matching into a plastic surgery (PS) residency program is a highly competitive process. Selection criteria are very stringent and may influence an applicant's candidacy and application strategy. The purpose of this study was to evaluate recent trends of applicants matching into integrated PS programs using published National Resident Match Program data. Residency match data were gathered for application years 2002 to 2011 using the National Resident Match Program/Association of American Medical Colleges databases. Analyses were limited to the US senior group and excluded the non-US senior group because of the small numbers in the latter group. For all data sets, a logistic regression was performed to analyze the statistical significance of the data. The overall match rate continues to approximately 50%. United States senior applicants were more likely to rank PS only versus PS and others (PS + other) over time (P ranking PS only were more likely to match versus US senior applicants ranking PS + other (odds ratio, 1.71; P rank PS only. The proportion of applicants ranking PS only is steadily rising. The ranking strategy used by US senior applicants is self-selecting into a more competitive (PS only) and less competitive (PS + other) applicant pool. If this continues, nearly 50% of applicants will not match and could be left scrambling for an alternative residency position. These findings therefore suggest that all candidates, regardless of their perceived application strength, should consider having a "backup plan."

  6. Quantifying riverine and storm-surge flood risk by single-family residence: application to Texas. (United States)

    Czajkowski, Jeffrey; Kunreuther, Howard; Michel-Kerjan, Erwann


    The development of catastrophe models in recent years allows for assessment of the flood hazard much more effectively than when the federally run National Flood Insurance Program (NFIP) was created in 1968. We propose and then demonstrate a methodological approach to determine pure premiums based on the entire distribution of possible flood events. We apply hazard, exposure, and vulnerability analyses to a sample of 300,000 single-family residences in two counties in Texas (Travis and Galveston) using state-of-the-art flood catastrophe models. Even in zones of similar flood risk classification by FEMA there is substantial variation in exposure between coastal and inland flood risk. For instance, homes in the designated moderate-risk X500/B zones in Galveston are exposed to a flood risk on average 2.5 times greater than residences in X500/B zones in Travis. The results also show very similar average annual loss (corrected for exposure) for a number of residences despite their being in different FEMA flood zones. We also find significant storm-surge exposure outside of the FEMA designated storm-surge risk zones. Taken together these findings highlight the importance of a microanalysis of flood exposure.

  8. Scholar in Residence: an innovative application of the scholarship of engagement. (United States)

    Jacelon, Cynthia S; Donoghue, Linda Carey; Breslin, Eileen


    Universities are expected to engage with communities for the benefit of both. Based on the definition of scholarship advanced by Boyer in the 1990s, inclusive of the scholarship of discovery, integration, teaching, and application, the School of Nursing and Jewish Geriatric Services, Inc., have instituted a unique collaboration entitled the Scholar in Residence. Unlike traditional agreements between schools of nursing and agencies to provide clinical experience and educate students, this agreement is designed to build scholarship for both university and agency. Outcomes include building opportunities for faculty and staff scholarship at the agency, enhancing the integration of knowledge into practice, intensifying opportunities for the sharing of knowledge by providing opportunities for students to work with faculty and staff on individual projects, and enriching the application of knowledge by providing opportunities for faculty clinical practice and consultation. The Scholar in Residence is a model of collaboration between the university and the community that reflects the mission of the university and provides value to the community agency through strategic engagement of both entities.

  12. Relationship between fiber degradation and residence time distribution in the processing of long fiber reinforced thermoplastics

    Directory of Open Access Journals (Sweden)


    Full Text Available Long fiber reinforced thermoplastics (LFT were processed by in-line compounding equipment with a modified single screw extruder. A pulse stimulus response technique using PET spheres as the tracer was adopted to obtain residence time distribution (RTD of extrusion compounding. RTD curves were fitted by the model based on the supposition that extrusion compounding was the combination of plug flow and mixed flow. Characteristic parameters of RTD model including P the fraction of plug flow reactor (PFR and d the fraction of dead volume of continuous stirred tank reactor (CSTR were used to associate with fiber degradation presented by fiber length and dispersion. The effects of screw speed, mixing length and channel depth on RTD curves, and characteristic parameters of RTD models as well as their effects on the fiber degradation were investigated. The influence of shear force with different screw speeds and variable channel depth on fiber degradation was studied and the main impetus of fiber degradation was also presented. The optimal process for obtaining the balance of fiber length and dispersion was presented.

  4. Evaluation of the Current Perspectives on Letters of Recommendation for Residency Applicants among Plastic Surgery Program Directors

    Directory of Open Access Journals (Sweden)

    K. Shultz


    Full Text Available Background. The goals of this project were to evaluate the current perspective on letters of recommendation and to assess the need for, and acceptance of, a more standardized letter of recommendation (LOR. Methods. An eight-question survey was distributed to plastic surgery program directors. A five-point Likert scale was selected as a means of quantifying the participants’ responses to the survey. Results. Twenty-eight of 71 program directors (39.4% completed the survey. The majority of participants felt that current LOR did not offer a realistic way to compare applicants (mean±SD, 2.9±0.8. While most agreed that increasing the objectivity of LOR would be valuable in comparing applicants (mean±SD, 4.1±0.9, the overall average response to whether a more standardized letter format would improve the resident selection process remained only slightly better than neutral (mean±SD, 3.5±1.2. Most of the chairmen supported the notion that familiarity with the author of the LOR strengthened the recommendation (mean±SD, 4.5±0.6. Conclusion. The majority of plastic surgery program directors would like more objectivity in comparing applicants but are ambivalent about a standardized letter of recommendation.

  6. Ultrasound Applications in Food Processing (United States)

    Bermúdez-Aguirre, Daniela; Mobbs, Tamara; Barbosa-Cánovas, Gustavo V.

    Food scientists today are focused on the development of not only microbiologically safe products with a long storage life, but, at the same time, products that have fresh-like characteristics and a high quality in taste, flavor, and texture. This focus is based on the needs of the consumer, which is one of the main reasons for constant research in the so-called area of emerging technologies. Traditionally, thermal treatments have been used to produce safe food products. Pasteurization of juice, milk, beer, and wine is a common process in which the final product has a storage life of some weeks (generally under refrigeration). However, vitamins, taste, color, and other sensorial characteristics are decreased with this treatment. High temperature is responsible for these effects and can be observed in the loss of nutritional components and changes in flavor, taste, and texture, often creating the need for additives to improve the product.

  7. Discrimination against international medical graduates in the United States residency program selection process. (United States)

    Desbiens, Norman A; Vidaillet, Humberto J


    Available evidence suggests that international medical graduates have improved the availability of U.S. health care while maintaining academic standards. We wondered whether studies had been conducted to address how international graduates were treated in the post-graduate selection process compared to U.S. graduates. We conducted a Medline search for research on the selection process. Two studies provide strong evidence that psychiatry and family practice programs respond to identical requests for applications at least 80% more often for U.S. medical graduates than for international graduates. In a third study, a survey of surgical program directors, over 70% perceived that there was discrimination against international graduates in the selection process. There is sufficient evidence to support action against discrimination in the selection process. Medical organizations should publish explicit proscriptions of discrimination against international medical graduates (as the American Psychiatric Association has done) and promote them in diversity statements. They should develop uniform and transparent policies for program directors to use to select applicants that minimize the possibility of non-academic discrimination, and the accreditation organization should monitor whether it is occurring. Whether there should be protectionism for U.S. graduates or whether post-graduate medical education should be an unfettered meritocracy needs to be openly discussed by medicine and society.

  11. Selection bias: Examining the feasibility, utility, and participant receptivity to incorporating simulation into the general surgery residency selection process. (United States)

    Gardner, Aimee K; Steffes, Christopher P; Nepomnayshy, Dmitry; Nicholas, Cate; Widmann, Warren D; Fitzgibbons, Shimae C; Dunkin, Brian J; Jones, Daniel B; Paige, John T


    Opportunities exist to revise the current residency selection process to capture desirable candidate competencies. We examined the extent to which components of the American College of Surgeons/Association for Surgical Education simulation-based medical student curriculum combined with a teamwork activity could be used as potential screening method. Students participated in a workshop consisting of training/evaluation of knot tying, suturing, airway management, gowning/gloving, and teamwork. Surveys were given to medical students (MS) and faculty/resident/staff (FRS) to examine their opinions about the residency screening process, the most critical competencies to assess, and the effectiveness of each station for candidate evaluation. Communication (FRS, 4.86 ± .35; MS, 4.93 ± .26), leadership (FRS, 4.41 ± .80; MS, 4.5 ± .76), judgment (FRS, 4.62 ± .74; MS, 4.67 ± .62), professionalism (FRS, 4.64 ± .73; MS, 5.00 ± .00), integrity (FRS, 4.71 ± .78; MS, 4.87 ± .35), and grit/resilience (FRS, 4.71 ± .78; MS, 4.53 ± .74) were considered most valuable for candidate screening. The simulation-based curriculum for evaluation of residency candidates was rated lowest by both groups. Open response comments indicated positive perceptions of this process. Employing simulation to assess candidates may be most beneficial for examining nontechnical attributes. Future work should continue to explore this area. Copyright © 2016 Elsevier Inc.

    Understand, through the theory of social representations, the influence exerted by the establishment a residency program in anesthesiology on anesthetic care and professional motivation in a tertiary teaching hospital in the Northeast of Brazil. Qualitative methodology. The theoretical framework comprised the phenomenology and the Social Representation Theory. Five multidisciplinary focus groups were formed with 17 health professionals (five surgeons, five anesthesiologists, two nurses, and five nursing technicians), who work in operating rooms and post-anesthesia care units, all with prior and posterior experience to the establishment of residency. From the response content analysis, the following empirical categories emerged: motivation to upgrade, recycling of anesthesiologists and improving anesthetic practice, resident as an interdisciplinary link in perioperative care, improvements in the quality of perioperative care, recognition of weaknesses in the perioperative process. It was evident upper gastrointestinal bleeding secondary to prolonged intubation that the creation of a residency in anesthesiology brings advancements that are reflected in the motivation of anesthesiologists; the resident worked as an interdisciplinary link between the multidisciplinary team; there was recognition of weaknesses in the system, which were identified and actions to overcome it were proposed. The implementation of a residency program in anesthesiology at a tertiary education hospital in the Northeast of Brazil promoted scientific updates, improved the quality of care and processes of interdisciplinary care, recognized the weaknesses of the service, developed action plans and suggested that this type of initiative may be useful in remote areas of developing countries.

  19. Observational study using the tools of lean six sigma to improve the efficiency of the resident rounding process. (United States)

    Chand, David V


    Recent focus on resident work hours has challenged residency programs to modify their curricula to meet established duty hour restrictions and fulfill their mission to develop the next generation of clinicians. Simultaneously, health care systems strive to deliver efficient, high-quality care to patients and families. The primary goal of this observational study was to use a data-driven approach to eliminate examples of waste and variation identified in resident rounding using Lean Six Sigma methodology. A secondary goal was to improve the efficiency of the rounding process, as measured by the reduction in nonvalue-added time. We used the "DMAIC" methodology: define, measure, analyze, improve, and control. Pediatric and family medicine residents rotating on the pediatric hospitalist team participated in the observation phase. Residents, nurses, hospitalists, and parents of patients completed surveys to gauge their attitudes toward rounds. The Mann-Whitney test was used to test for differences in the median times measured during the preimprovement and postimprovement phases, and the Student t test was used for comparison of survey data. Collaborative, family-centered rounding with elimination of the "prerounding" process, as well as standard work instructions and pacing the process to meet customer demand (takt time), were implemented. Nonvalue-added time per patient was reduced by 64% (P  =  .005). Survey data suggested that team members preferred the collaborative, family-centered approach to the traditional model of rounding. Lean Six Sigma provides tools, a philosophy, and a structured, data-driven approach to address a problem. In our case this facilitated an effort to adhere to duty hour restrictions while promoting education and quality care. Such approaches will become increasingly useful as health care delivery and education continue to transform.

  5. Applying advanced digital signal processing techniques in industrial radioisotopes applications

    International Nuclear Information System (INIS)

    Mahmoud, H.K.A.E.


    Radioisotopes can be used to obtain signals or images in order to recognize the information inside the industrial systems. The main problems of using these techniques are the difficulty of identification of the obtained signals or images and the requirement of skilled experts for the interpretation process of the output data of these applications. Now, the interpretation of the output data from these applications is performed mainly manually, depending heavily on the skills and the experience of trained operators. This process is time consuming and the results typically suffer from inconsistency and errors. The objective of the thesis is to apply the advanced digital signal processing techniques for improving the treatment and the interpretation of the output data from the different Industrial Radioisotopes Applications (IRA). This thesis focuses on two IRA; the Residence Time Distribution (RTD) measurement and the defect inspection of welded pipes using a gamma source (gamma radiography). In RTD measurement application, this thesis presents methods for signal pre-processing and modeling of the RTD signals. Simulation results have been presented for two case studies. The first case study is a laboratory experiment for measuring the RTD in a water flow rig. The second case study is an experiment for measuring the RTD in a phosphate production unit. The thesis proposes an approach for RTD signal identification in the presence of noise. In this approach, after signal processing, the Mel Frequency Cepstral Coefficients (MFCCs) and polynomial coefficients are extracted from the processed signal or from one of its transforms. The Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT), and Discrete Sine Transform (DST) have been tested and compared for efficient feature extraction. Neural networks have been used for matching of the extracted features. Furthermore, the Power Density Spectrum (PDS) of the RTD signal has been also used instead of the discrete

  6. Application of High Pressure in Food Processing

    Directory of Open Access Journals (Sweden)

    Herceg, Z.


    Full Text Available In high pressure processing, foods are subjected to pressures generally in the range of 100 – 800 (1200 MPa. The processing temperature during pressure treatments can be adjusted from below 0 °C to above 100 °C, with exposure times ranging from a few seconds to 20 minutes and even longer, depending on process conditions. The effects of high pressure are system volume reduction and acceleration of reactions that lead to volume reduction. The main areas of interest regarding high-pressure processing of food include: inactivation of microorganisms, modification of biopolymers, quality retention (especially in terms of flavour and colour, and changes in product functionality. Food components responsible for the nutritive value and sensory properties of food remain unaffected by high pressure. Based on the theoretical background of high-pressure processing and taking into account its advantages and limitations, this paper aims to show its possible application in food processing. The paper gives an outline of the special equipment used in highpressure processing. Typical high pressure equipment in which pressure can be generated either by direct or indirect compression are presented together with three major types of high pressure food processing: the conventional (batch system, semicontinuous and continuous systems. In addition to looking at this technology’s ability to inactivate microorganisms at room temperature, which makes it the ultimate alternative to thermal treatments, this paper also explores its application in dairy, meat, fruit and vegetable processing. Here presented are the effects of high-pressure treatment in milk and dairy processing on the inactivation of microorganisms and the modification of milk protein, which has a major impact on rennet coagulation and curd formation properties of treated milk. The possible application of this treatment in controlling cheese manufacture, ripening and safety is discussed. The opportunities

  7. Development of NIL processes for PV applications (United States)

    Hauser, H.; Tucher, N.; Tokai, K.; Schneider, P.; Wellens, Ch.; Volk, A.; Barke, S.; Müller, C.; Glinsner, T.; Bläsi, B.


    Due to its high resolution and applicability for large area patterning, Nanoimprint Lithography (NIL) is a promising technology for photovoltaic (PV) applications. However, a successful industrial application of NIL processes is only possible if large-area processing on thin, brittle and potentially rough substrates can be achieved in a high-throughput process. In this work, the development of NIL processes using the novel SmartNILTM technology from EV Group with a focus on PV applications is described. We applied this tooling to realize a honeycomb texture (8 μm period) on the front side of multicrystalline silicon solar cells leading to an improvement in optical efficiency of 7% relative and a total efficiency gain of 0.5% absolute compared to the industrial standard texture (isotexture). On the rear side of monocrystalline silicon solar cells, we realized diffraction gratings to make use of light trapping effects. An absorption enhancement of up to 35% absolute at a wavelength of 1100 nm is demonstrated. Furthermore, we combined photolithography and NIL processes to introduce features for metal contacts into honeycomb master structures, which initially were realized using interference lithography. As final application, we investigated the realization of very fine contact fingers with prismatic shape in order to minimize reflection losses.

    Anaerobic ammonium oxidation (ANAMMOX), as its essential advantages of high efficiency and low cost, is a promising novel biological nitrogen elimination process with attractive application prospects. Over the past two decades, many processes based on the ANAMMOX reaction have been continuously studied and applied to practical engineering, with the perspective of reaching 100 full-scale installations in operation worldwide by 2014. Our review summarizes various forms of ANAMMOX processes, including partial nitritation-ANAMMOX, completely autotrophic nitrogen removal over nitrite, oxygen limited autotrophic nitrification and denitrification, denitrifying ammonium oxidation, aerobic deammonification, simultaneous partial nitrification, ANAMMOX and denitrification, single-stage nitrogen removal using ANAMMOX and partial nitritation. We also compare the operating conditions for one-stage and two-stage processes and summarize the obstacles and countermeasures in engineering application of ANAMMOX systems, such as moving bed biofilm reactor, sequencing batch reactor and granular sludge reactor. Finally, we discuss the future research and application direction, which should focus on the optimization of operating conditions and applicability of the process to the actual wastewater, especially on automated control and the impact of special wastewater composition on process performance.

    Peterson, Kenneth Allen; Krueger, Daniel S. (NNSA, Kansas City, MO); Sandoval, Charles E.


    Low Temperature Cofired Ceramic has proven itself in microelectronics, microsystems (including microfluidic systems), sensors, RF features, and various non-electronic applications. We will discuss selected applications and the processing associated with those applications. We will then focus on our recent work in the area of EMI shielding using full tape thickness features (FTTF) and sidewall metallization. The FTTF is very effective in applications with -150 dB isolation requirements, but presents obvious processing difficulties in full-scale fabrication. The FTTF forms a single continuous solid wall around the volume to be shielded by using sequential punching and feature-filling. We discuss the material incompatibilities and manufacturing considerations that need to be addressed for such structures and show preliminary implementations.

    Johnson, G.M.


    The impact of parallel processing on computational science and, in particular, on computational fluid dynamics is growing rapidly. In this paper, particular emphasis is given to developments which have occurred within the past two years. Parallel processing is defined and the reasons for its importance in high-performance computing are reviewed. Parallel computer architectures are classified according to the number and power of their processing units, their memory, and the nature of their connection scheme. Architectures which show promise for fluid dynamics applications are emphasized. Fluid dynamics problems are examined for parallelism inherent at the physical level. CFD algorithms and their mappings onto parallel architectures are discussed. Several example are presented to document the performance of fluid dynamics applications on present-generation parallel processing devices

    Wojnarwsky, Pandora Keala Lee; Wang, Yan; Shah, Kumar; Koka, Sreenivas


    The decision by prosthodontic residency program directors to employ the Match process highlights the need to understand applicant priorities that influence their choice of which programs to rank highly. The purpose of this study is to determine the factors that were most important to residents when choosing from among nonmilitary based prosthodontics dental residency programs in the United States. Following completion of a pilot study, all currently enrolled prosthodontic residents at nonmilitary residency programs were invited to participate via the internet. The study consisted of a survey instrument asking residents to rank 26 possible factors that might impact an applicant's choice of residency program. In addition, the instrument collected other possible influencing variables including gender and debt load. Mean rank scores were compared to determine the most and least important factors. Kruskal-Wallis test was used to compare specific factors between the possible influencing variables. Two hundred and thirty residents completed the survey instrument, representing a 54.1% response rate of possible participants. With regard to factors influencing program choice, reputation of the residency program was the factor ranked the highest by participants, followed in descending order by the program director's personality, curriculum content, access to use of the latest digital technology, and opportunities for dental implant placement. Quality of schools for children, community outreach opportunities, and the ability to moonlight were ranked as the least important factors. Male and female residents ranked factors such as tuition/stipend, curriculum content, and community outreach opportunities significantly differently. Depending on debt load, residents ranked the factors tuition/stipend, ability to moonlight, curriculum content, and safety of the area where the program is differently. Current prosthodontic residents valued the reputation of the program as the most

    Introduction Digital media have revolutionized communication and information dissemination in healthcare. We aimed to quantify and evaluate professional digital media use among urology residents. Methods We designed a 17-item survey to assess usage and perceived usefulness of digital media, as well as communication type and device type and distributed it via email to 143 Canadian and 721 German urology residents. Results In total, 58 (41% response rate) residents from Canada and 170 (24% response rate) from Germany reported professional usage rates of 100% on the internet, 89% on apps, and 46% on social media (SoMe). For professional use, residents spent a median of 30 minutes per day on the internet, 10 minutes on apps, and 15 minutes on SoMe. 100% rated the internet, 89% apps, and 31% SoMe as useful for clinical practice. Most (94%) used digital media for communication with colleagues and 23% for communication with patients. Digital media use was allocated to desktop computers (55%) and mobile devices (45%). Canadian residents had higher usage rates of apps (96% vs. 86%; p=0.042) and SoMe (65% vs. 39%; p=0.002) and longer daily usage times for the internet, apps, and SoMe than German residents (pmedia are an integral part of the daily professional practice of urology residents, reflected by high usage rates and perceived usefulness of the internet and apps, and the growing importance of SoMe. Urologists should strive to progressively exhaust the vast potential of digital media for academic and clinical practice. PMID:29382458

    The 0 + 5 integrated vascular surgery (VS) residency has altered the training paradigm for future vascular specialists. Rising interest in these novel programs highlights our need to better understand the applicant pool. We compared demographics and surveyed recent applicants to our integrated program to gain more insight into their background and motivation for accelerated vascular training. Demographics and objective parameters were determined from all 65 applicants to the integrated VS program at Stanford University Medical Center and compared to 58 applicants interviewed by the general surgery (GS) program at Harbor-UCLA Medical Center by querying the Electronic Residency Application System for the programs in 2009. There was no overlap of applicants between programs. An anonymous, voluntary Web-based survey was sent to these cohorts with a response rate of 82% for VS applicants and 60% for GS applicants. Subjects were queried regarding their background, personal experience, prior exposure to VS, and motivations for residency specialty selection. Applicants to integrated VS programs tended to be older, were less likely to be from a US medical school, had a higher number of publications, and a higher percentage of cardiovascular-related publications than the GS applicants. When stratified by the 27 VS applicants (41%) that were offered an interview, this highly selected and desirable group for training was nearly 40% female, more likely to have an additional degree (PhD, master's), just as likely to be in the top quartile of their medical school class (60%), and score equally well on standardized board examinations (90th percentile) than the top GS applicants offered interviews. Survey data revealed that the majority of career choices (65%) were made during the third and fourth years of medical school. Factors most strongly influencing the decision to choose VS as a career were endovascular technologies/devices, challenging open vascular operations, clinical

  17. Gravity models to classify commuting vs. resident workers. An application to the analysis of residential risk in a contaminated area. (United States)

    Signorino, Guido; Pasetto, Roberto; Gatto, Elisa; Mucciardi, Massimo; La Rocca, Marina; Mudu, Pierpaolo


    The analysis of risk for the population residing and/or working in contaminated areas raises the topic of commuting. In fact, especially in contaminated areas, commuting groups are likely to be subject to lower exposure than residents. Only very recently environmental epidemiology has started considering the role of commuting as a differential source of exposure in contaminated areas. In order to improve the categorization of groups, this paper applies a gravitational model to the analysis of residential risk for workers in the Gela petrochemical complex, which began life in the early 60s in the municipality of Gela (Sicily, Italy) and is the main source of industrial pollution in the local area. A logistic regression model is implemented to measure the capacity of Gela "central location" to attract commuting flows from other sites. Drawing from gravity models, the proposed methodology: a) defines the probability of finding commuters from municipalities outside Gela as a function of the origin's "economic mass" and of its distance from each destination; b) establishes "commuting thresholds" relative to the origin's mass. The analysis includes 367 out of the 390 Sicilian municipalities. Results are applied to define "commuters" and "residents" within the cohort of petrochemical workers. The study population is composed of 5,627 workers. Different categories of residence in Gela are compared calculating Mortality Rate Ratios for lung cancer through a Poisson regression model, controlling for age and calendar period. The mobility model correctly classifies almost 90% of observations. Its application to the mortality analysis confirms a major risk for lung cancer associated with residence in Gela. Commuting is a critical aspect of the health-environment relationship in contaminated areas. The proposed methodology can be replicated to different contexts when residential information is lacking or unreliable; however, a careful consideration of the territorial

    Oros, C.


    An overview of the state-of-the-art in laser material processing for a large types of lasers from IR (CO 2 laser, NdYAG laser) to UV (excimer laser) and different kinds of materials (metals, dielectrics) is given. Laser radiation has found a wide range of applications as machining tool for various kinds of materials processing. The machining geometry, the work piece geometry, the material properties and economic productivity claim for customized systems with special design for beam guiding, shaping and delivery in order to fully utilize the laser radiation for surface processing with optimum efficiency, maximum processing speed and high processing quality. The laser-material interaction involves complex processes of heating, melting, vaporization, ejection of atoms, ions, and molecules, shock waves, plasma initiation and plasma expansion. The interaction is dependent on the laser beam parameters (pulse duration, energy and wavelength), the solid target properties and the surrounding environments condition. Experimental results for laser surface melting and laser ablation are given. Also, assuming the applicability of a one dimensional model for short pulses used, and restricting condition to single-pulse exposure, the temperature rise on the target was calculated taking account of the finite optical absorption depth and pulse duration of the laser

    Computing power performance was important at times when hardware was still expensive, because hardware had to be put to the best use. Later on this criterion was no longer critical, since hardware had become inexpensive. Meanwhile, however, people have realized that performance again plays a significant role, because of the major drain on system resources involved in developing complex applications. This book distinguishes between three levels of performance optimization: the system level, application level and business processes level. On each, optimizations can be achieved and cost-cutting p

  1. Spacecraft Electrical Connector Selection and Application Processes (United States)

    Iannello, Chris; Davis, Mitchell I; Kichak, Robert A.; Slenski, George


    This assessment was initiated by the NASA Engineering & Safety Center (NESC) after a number of recent "high profile" connector problems, the most visible and publicized of these being the problem with the Space Shuttle's Engine Cut-Off System cryogenic feed-thru connector. The NESC commissioned a review of NASA's connector selection and application processes for space flight applications, including how lessons learned and past problem records are fed back into the processes to avoid recurring issues. Team members were primarily from the various NASA Centers and included connector and electrical parts specialists. The commissioned study was conducted on spacecraft connector selection and application processes at NASA Centers. The team also compared the NASA spacecraft connector selection and application process to the military process, identified recent high profile connector failures, and analyzed problem report data looking for trends and common occurrences. The team characterized NASA's connector problem experience into a list of top connector issues based on anecdotal evidence of a system's impact and commonality between Centers. These top issues are as follows, in no particular rank order: electrically shorted, bent and/or recessed contact pins, contact pin/socket contamination leading to electrically open or intermittencies, connector plating corrosion or corrosion of connector components, low or inadequate contact pin retention forces, contact crimp failures, unmated connectors and mis-wiring due to workmanship errors during installation or maintenance, loose connectors due to manufacturing defects such as wavy washer and worn bayonet retention, damaged connector elastomeric seals and cryogenic connector failure. A survey was also conducted of SAE Connector AE-8C1 committee members regarding their experience relative to the NASA concerns on connectors. The most common responses in order of occurrence were contact retention, plating issues, worn-out or damaged

  4. Stochastic MPC with applications to process control (United States)

    Jurado, I.; Millán, P.; Quevedo, D.; Rubio, F. R.


    This paper presents a model predictive control formulation for Networked Control Systems subject to independent and identically distributed delays and packet dropouts. The design takes into account the presence of a communication network in the control loop, resorting to a buffer at the actuator side to store and consistently apply delayed control sequences when fresh control inputs are not available. The proposed approach uses a statistical description of transmissions to optimise the expected future control performance conditioned upon the current system state, previously calculated control packets and transmission acknowledgements. Experimental studies using a quadruple tank process illustrate the applicability of the method to process control.

  5. Atmospheric Pressure Plasma Process And Applications

    Energy Technology Data Exchange (ETDEWEB)

    Peter C. Kong; Myrtle


    This paper provides a general discussion of atmospheric-pressure plasma generation, processes, and applications. There are two distinct categories of atmospheric-pressure plasmas: thermal and nonthermal. Thermal atmospheric-pressure plasmas include those produced in high intensity arcs, plasma torches, or in high intensity, high frequency discharges. Although nonthermal plasmas are at room temperatures, they are extremely effective in producing activated species, e.g., free radicals and excited state atoms. Thus, both thermal and nonthermal atmosphericpressure plasmas are finding applications in a wide variety of industrial processes, e.g. waste destruction, material recovery, extractive metallurgy, powder synthesis, and energy conversion. A brief discussion of recent plasma technology research and development activities at the Idaho National Laboratory is included.

  9. Applications of Radiation Processing in Industry

    International Nuclear Information System (INIS)

    Abad, Lucille V.


    Radiation processing has long been known as commercially viable technology that can be beneficially used to enhance the characteristics of many materials. Several gamma irradiators and electron beam accelerators are operating worldwide which are utilized for various established industrial applications. These could be used for the following processes: a) radiation crosslinking e.g. crosslinking of wires and cables, heat shrinkable film and tube productions, manufacture of plastic bags and tubings for medical products, pre-curing of automobile tire components, curing of polymeric coatings, etc. b) radiation degradation e.g. Scrap Teflon (Polytetraflouroethylene) to form powders, disinfestations and pasteurization of agricultural products, sterilization of medical products, etc.; and c) radiation grafting e.g. grafted non-woven fabrics for metal adsorbent. Emerging applications for radiation processing include grafted membranes for fuel cell, electrodes, cell sheet for tissue engineering, nanoparticle production, polymer composite synthesis, and fibrous catalyst for biodiesel production. Current researches at the Philippine Nuclear Research Institute consist of crosslinking of natural and synthetic polymers for medical application e.g. wound dressing, hemostats, and bioimplants for vesicouretal reflux (VUR); grafting of natural and synthetic fabrics for metal adsorbents; and radiation degradation of carrageenan as plant growth promoter.

  10. The process of co-creating the interface for VENSTER, an interactive artwork for nursing home residents with dementia. (United States)

    Jamin, Gaston; Luyten, Tom; Delsing, Rob; Braun, Susy


    Interactive art installations might engage nursing home residents with dementia. The main aim of this article was to describe the challenging design process of an interactive artwork for nursing home residents, in co-creation with all stakeholders and to share the used methods and lessons learned. This process is illustrated by the design of the interface of VENSTER as a case. Nursing home residents from the psychogeriatric ward, informal caregivers, client representatives, health care professionals and members of the management team were involved in the design process, which consisted of three phases: (1) identify requirements, (2) develop a prototype and (3) conduct usability tests. Several methods were used (e.g. guided co-creation sessions, "Wizard of Oz"). Each phase generated "lessons learned", which were used as the departure point of the next phase. Participants hardly paid attention to the installation and interface. There, however, seemed to be an untapped potential for creating an immersive experience by focussing more on the content itself as an interface (e.g. creating specific scenes with cues for interaction, scenes based on existing knowledge or prior experiences). "Fifteen lessons learned" which can potentially assist the design of an interactive artwork for nursing home residents suffering from dementia were derived from the design process. This description provides tools and best practices for stakeholders to make (better) informed choices during the creation of interactive artworks. It also illustrates how co-design can make the difference between designing a pleasurable experience and a meaningful one. Implications for rehabilitation Co-design with all stakeholders can make the difference between designing a pleasurable experience and a meaningful one. There seems to be an untapped potential for creating an immersive experience by focussing more on the content itself as an interface (e.g. creating specific scenes with cues for interaction

  11. Applications of plutonium dioxide oxydising dissolution process

    International Nuclear Information System (INIS)

    Lecomte, M.; Bourges, J.; Madic, C.


    Laboratory investigations having demonstrated the outstanding effectiveness of Ag 2+ ions for the dissolution of plutonium dioxide in nitric medium, two applications of this method were developed at the CEA: dissolution of off-standard PuO 2 , recovery of the plutonium contained in ashes produced by incineration of solid wastes. With respect to PuO 2 dissolution, the parametric investigation of the electrogeneration of Ag (II) and of its reaction with PuO 2 , led to the development of a process and of the equipment required for its implementation. The prototype facility used to dissolve in 4 hours 1 kg of plutonium, in oxide form, was built and tested in the laboratory. This equipment was used to dissolve 30 kg of plutonium oxide in batches of about 700 grams. An in-line spectrophotometric method was developed for process control. The application of this process to the recovery of plutonium from incineration ash is currently being developed. Tested on the scale of about 1 kg of ash, the process helps to recover the plutonium with yields higher than 98 % [fr

  12. Modeling sediment transport processes and residence times in the shallow coastal bay complex of the Virginia Coast Reserve (United States)

    Safak, I.; Wiberg, P. L.


    Patterns of sediment transport and particle residence times influence the morphology and ecology of shallow coastal bays in important ways. The Virginia Coast Reserve (VCR), a barrier island-lagoon-marsh system on the Eastern Shore of Virginia, is typical of many shallow coastal bay complexes that lack a significant fluvial source of freshwater and sediment. Sediment redistribution within the bays in response to storms and sea-level rise, together with the dynamics of marsh and lagoon-bottom plants, largely governs the morphological evolution of this system. There are also important feedbacks between sediment and ecosystem dynamics. This is particularly true in the VCR, which is relatively unaffected by human activities. As a step towards evaluating the impact of hydrodynamics on sediment and ecological processes in the VCR, a single unified model that accounts for circulation, surface waves, wave-current interaction, and sediment processes is employed. This three-dimensional unstructured grid finite-volume coastal ocean model (FVCOM) is validated with field observations of wind- and tide-induced water flow (water level and current velocities) in Hog Island Bay, centrally located within the VCR. Here, the resulting patterns of sediment transport and particle residence times over event and seasonal time scales are presented. Water and particle exchange within the VCR and between the VCR and the ocean is examined with the Lagrangian particle-tracking module in FVCOM. We focus on three bays with strongly varying bathymetry and coastline geometry, which are also located along a gradient of nitrogen input to the system. The results indicate that residence time of particles within the system vary greatly depending on the location of particle release, bay morphology, and wind conditions. The implications for morphologic evolution and ecosystem response to climate and land-use changes are evaluated.

  13. Relating hyporheic fluxes, residence times, and redox-sensitive biogeochemical processes upstream of beaver dams (United States)

    Briggs, Martin A.; Lautz, Laura; Hare, Danielle K.


    Abstract. Small dams enhance the development of patchy microenvironments along stream corridors by trapping sediment and creating complex streambed morphologies. This patchiness drives intricate hyporheic flux patterns that govern the exchange of O2 and redox-sensitive solutes between the water column and the stream bed. We used multiple tracer techniques, naturally occurring and injected, to evaluate hyporheic flow dynamics and associated biogeochemical cycling and microbial reactivity around 2 beaver dams in Wyoming (USA). High-resolution fiber-optic distributed temperature sensing was used to collect temperature data over 9 vertical streambed profiles and to generate comprehensive vertical flux maps using 1-dimensional (1-D) heat-transport modeling. Coincident with these locations, vertical profiles of hyporheic water were collected every week and analyzed for dissolved O2, pH, dissolved organic C, and several conservative and redox-sensitive solutes. In addition, hyporheic and net stream aerobic microbial reactivity were analyzed with a constant-rate injection of the biologically sensitive resazurin (Raz) smart tracer. The combined results revealed a heterogeneous system with rates of downwelling hyporheic flow organized by morphologic unit and tightly coupled to the redox conditions of the subsurface. Principal component analysis was used to summarize the variability of all redox-sensitive species, and results indicated that hyporheic water varied from oxic-stream-like to anoxic-reduced in direct response to the hydrodynamic conditions and associated residence times.

  14. Resident Selection Beyond the United States Medical Licensing Examination. (United States)

    Porter, Scott E; Graves, Matt


    The resident application process has matured over the decades to become an efficient system. An unforeseen consequence of this efficiency is the massive number of applications that each orthopaedic surgery residency program must sort through to arrive at a manageable rank list. The most widely used filter in today's application cycle is an applicant's performance on the United States Medical Licensing Examination Step 1. Although no evidence exists to prove that this examination is predictive of any of the potentially defining characteristics of a successful resident, orthopaedic surgery programs historically have had few alternative options. A growing body of literature suggests that a more focused investigation of an applicant's inherent personality traits, as evidenced by his or her past accomplishments, as well as a structured use of questionnaires as part of the application process may improve the ability of orthopaedic surgery residency programs to predict who will be a successful resident.

  15. A qualitative study of sign-out processes between primary and on-call residents: relationships in information exchange, responsibility and accountability. (United States)

    Lee, Soo-Hoon; Fisher, Dale A; Mah, Heidi; Goh, Wei-Ping; Phan, Phillip H


    To review a quality improvement event on the process of sign-outs between the primary and on-call residents. A retrospective qualitative study using semi-structured interviews. A tertiary academic medical center in Singapore with 283 inpatient Medicine beds served by 28 consultants, 29 registrars, 45 residents and 30 interns during the day but 5 residents and 3 interns at night. Residents, registrars and consultants. Quality improvement event on sign-out. Effectiveness of sign-out comprises exchange of patient information, professional responsibility and task accountability. The following process of sign-outs was noted. Primary teams were accountable to the on-call resident by selecting at-risk patients and preparing contingency plans for sign-out. Structured information exchanged included patient history, active problems and plans of care. On-call residents took ownership of at-risk patients by actively asking questions during sign-out and reporting back the agreed care plan. On-call residents were accountable to the primary team by reporting back at-risk patients the next day. A structured information exchange at sign-out increased the on-call resident's ability to care for at-risk patients when it was supported by two-way transfers of responsibility and accountability. © The Author 2017.

  17. Modelling and application of stochastic processes

    CERN Document Server


    The subject of modelling and application of stochastic processes is too vast to be exhausted in a single volume. In this book, attention is focused on a small subset of this vast subject. The primary emphasis is on realization and approximation of stochastic systems. Recently there has been considerable interest in the stochastic realization problem, and hence, an attempt has been made here to collect in one place some of the more recent approaches and algorithms for solving the stochastic realiza­ tion problem. Various different approaches for realizing linear minimum-phase systems, linear nonminimum-phase systems, and bilinear systems are presented. These approaches range from time-domain methods to spectral-domain methods. An overview of the chapter contents briefly describes these approaches. Also, in most of these chapters special attention is given to the problem of developing numerically ef­ ficient algorithms for obtaining reduced-order (approximate) stochastic realizations. On the application side,...

  18. Ravenna from imperial residence to episcopal city: processes of centrality across empires

    Directory of Open Access Journals (Sweden)

    Salvatore Cosentino


    Full Text Available From Late Antiquity to the early Middle Ages, two basic factor shaped Ravenna’s ability to influence a much more extensive space than its natural hinterland. The first was its establishment as an imperial residence the second was its location within the northern Adriatic basin, which had since Antiquity been a crossroads for peoples, trade and cultures. Just on the basis of the support it received from the imperial power, its episcopate was elevated to one of the most important sees of Italy. By means of the large international harbour of Classe, from the 5th to the 7th centuries the city imported products from around the entire Mediterranean. With the arrival of the Byzantine government, the ties between the port of Classe and the other Mediterranean export centres shifted by moving from West to East. Moreover, the relationship with Constantinople reaffirmed the political and ecclesiastical importance of Ravenna. As long as these ties remained strong, Ravenna retained a vital contact to the other maritime Mediterranean trade centres. The twilight of Byzantine rule did not cause the decline of the city, but rather a progressive turn of its ruling class toward the political scenario of the medieval West. By virtue of being the management centre of the patrimonium beati Apollinaris, the city remained wealthy and influential well beyond the 9th century. This was due both to the economic power of its archbishops and to their alliance with the Ottonians and then later with the Salian and Swabian emperors. The trajectories of the political centrality of Ravenna from Late Antiquity to the Middle Ages were, therefore, deeply influenced by the dynamic of successive empires, which, in one form or another, were all connected or attempted to reconnect to the memory of its Roman past.

  4. Survey of some natural decay-series isotopes in the Wairakei geothermal area and possible residence-time applications

    International Nuclear Information System (INIS)

    Concentrations of selected isotopes in the uranium decay series were determined for samples collected from the Wairakei, Broadlands/Ohaaki and Waiotapu areas. /sup 226/Ra concentrations were found to be low (0.05-0.22 dpm/l), similar to values reported in neutral hot springs at Tatun geothermal area, Taiwan, but lower than other geothermal systems (Yellowstone, USA, and Latera, Central Italy) (up to 25 dpm/l). The potential of /sup 226/Ra//sup 228/Ra ratios for indicating water residence times could not be explored because /sup 228/Ra data was not available. /sup 222/Rn concentrations are higher and related to steam fractions and CO/sub 2/ concentrations. The short half-life (3.8 days) makes /sup 222/Rn suitable for estimating residence times of radon in steam, and therefore the distance of travel of steam from its source (e.g., wells WK9 and 52). /sup 210/Pb and /sup 210/Po concentrations were very low and less than detection limits in many of the Wairakei waters; no residence time applications are apparent for these isotopes.

    Simon, Eric P; McClaflin, Richard; Zonca, Rachel; Mikuni, Karen; Chung, Willard; Etnyre, Ethan; Faucette, Lindsey; Oates, David; Merrill, Chuck


    Background and Objectives This pilot study provides a description and evaluation of process-oriented dynamic group psychotherapy for depression as a teaching modality for family medicine residents. The main purpose of using this modality was to teach family medicine residents a variety of psychological clinical skills. A secondary benefit of this modality was to provide in-house, primary care treatment to depressed patients, although the efficacy of this was not evaluated in the present study. Methods A 10-item, self-report, Likert-type questionnaire was administered to a convenience sample of family medicine residents who had participated in the program. Results Completed questionnaires were received from 100% of the family medicine resident participants. Responses to the questionnaires indicate that the residents felt they acquired a variety of clinical skills from the training modality, to include developing active listening and interviewing skills; methods to improve the doctor-patient relationship; increased skills in empathy, intuitive processes, and emotional support; a depth understanding of how intra-psychic conflicts and interpersonal problems contribute to depression; how to give effective feedback that promotes behavioral change; and how to place interventions at the appropriate level of change. Eighty-eight percent of residents indicated they would recommend this learning modality to a family medicine physician colleague. Conclusions The family medicine residents' responses to the questionnaires indicate that they perceived process-oriented dynamic group psychotherapy for depression as a constructive and beneficial modality for both patient care and learning a variety of clinical skills.

  6. Elementary process theory axiomatic introduction and applications

    CERN Document Server

    Cabbolet, Marcoen J T F


    Modern physics lacks a unitary theory that applies to all four fundamental interactions. This PhD thesis is a proposal for a single, complete, and coherent scheme of mathematically formulated elementary laws of nature. While the first chapter presents the general background, the second chapter addresses the method by which the main result has been developed. The next three chapters rigorously introduce the Elementary Process Theory, its mathematical foundations, and its applications to physics, cosmology and philosophy of mind. The final two chapters discuss the results and present the conclusions. Summarizing, the Elementary Process Theory is a scheme of seven well-formed closed expressions, written in the mathematical language of set matrix theory – a generalization of Zermelo-Fraenkel set theory. In the physical world, these seven expressions can be interpreted as elementary principles governing the universe at supersmall scale. The author critically confronts the theory with Quantum Mechanics and Genera...

  7. Application of supercritical fluid in nanolithographic processes. (United States)

    Zhou, Jijie


    The supercritical state provides an energetic environment in which high-aspect-ratio or active surface structures can be reacted, swelled, cleaned, or coated. Due to both low viscosity and low interfacial tension, reagent, solvent, rinsing and drying media of supercritical fluids can be efficiently delivered into the nanointerstices of a substrate. This article summarizes recent patents in the field of using supercritical fluids in nanolithographic processing methods such as drying, removal of lithographic resist, and formation of hybrid structures. Some of our recent efforts on restoring the collapsed on-chip nanotube arrays, and synthesizing zeolite-polymer hybrid membrane materials are exemplified as applications of supercritical fluids. Introducing supercritical effects may guide sustainable technologies for the development of green processes.

  9. Application of Electroporation Technique in Biofuel Processing

    Directory of Open Access Journals (Sweden)

    Yousuf Abu


    Full Text Available Biofuels production is mostly oriented with fermentation process, which requires fermentable sugar as nutrient for microbial growth. Lignocellulosic biomass (LCB represents the most attractive, low-cost feedstock for biofuel production, it is now arousing great interest. The cellulose that is embedded in the lignin matrix has an insoluble, highly-crystalline structure, so it is difficult to hydrolyze into fermentable sugar or cell protein. On the other hand, microbial lipid has been studying as substitute of plant oils or animal fat to produce biodiesel. It is still a great challenge to extract maximum lipid from microbial cells (yeast, fungi, algae investing minimum energy.Electroporation (EP of LCB results a significant increase in cell conductivity and permeability caused due to the application of an external electric field. EP is required to alter the size and structure of the biomass, to reduce the cellulose crystallinity, and increase their porosity as well as chemical composition, so that the hydrolysis of the carbohydrate fraction to monomeric sugars can be achieved rapidly and with greater yields. Furthermore, EP has a great potential to disrupt the microbial cell walls within few seconds to bring out the intracellular materials (lipid to the solution. Therefore, this study aims to describe the challenges and prospect of application of EP technique in biofuels processing.

  11. Probabilistic approach of water residence time and connectivity using Markov chains with application to tidal embayments (United States)

    Bacher, C.; Filgueira, R.; Guyondet, T.


    Markov chain analysis was recently proposed to assess the time scales and preferential pathways into biological or physical networks by computing residence time, first passage time, rates of transfer between nodes and number of passages in a node. We propose to adapt an algorithm already published for simple systems to physical systems described with a high resolution hydrodynamic model. The method is applied to bays and estuaries on the Eastern Coast of Canada for their interest in shellfish aquaculture. Current velocities have been computed by using a 2 dimensional grid of elements and circulation patterns were summarized by averaging Eulerian flows between adjacent elements. Flows and volumes allow computing probabilities of transition between elements and to assess the average time needed by virtual particles to move from one element to another, the rate of transfer between two elements, and the average residence time of each system. We also combined transfer rates and times to assess the main pathways of virtual particles released in farmed areas and the potential influence of farmed areas on other areas. We suggest that Markov chain is complementary to other sets of ecological indicators proposed to analyse the interactions between farmed areas - e.g., depletion index, carrying capacity assessment. Markov chain has several advantages with respect to the estimation of connectivity between pair of sites. It makes possible to estimate transfer rates and times at once in a very quick and efficient way, without the need to perform long term simulations of particle or tracer concentration.

  12. Integration of mobile technology in educational materials improves participation: creation of a novel smartphone application for resident education. (United States)

    Shaw, Christiana M; Tan, Sanda A


    Traditional education consists of didactics and book learning. Recently, technology has been integrated into graduate medical education, primarily in the form of simulation. The primary aim of this study was to investigate if a novel smartphone application using technology to engage learners would improve participation in an educational activity when compared with a daily e-mail format and how this use translated to performance on standardized testing. The UF Surgery App (App), which is a smartphone application, was developed to deliver 2 questions from a general surgery educational database every weekday from October to February 2013. The App, developed for iOS, featured a notification alarm and a reminder icon to actively engage the learner. Learners who used the App responded to multiple-choice questions and were provided instantaneous feedback in the form of a correct answer with an explanation. The response rate and answers were collected prospectively and compared with the American Board of Surgery In-Training Examination score. University of Florida, College of Medicine, Gainesville, Florida, a university teaching hospital. A total of 46 general surgical residents were enrolled in a university training program. Participation was voluntary. Overall, 26 of 46 (57%) residents participated. Of the users, 70% answered more than 20% of the questions, while 46% responded to more than 70% of questions. The percentage of correct answers on the App was positively correlated with standardized score (p = 0.005), percentage correct (p = 0.02), and percentile (p = 0.034) on the ABSITE examination. Technology can be used to actively engage residents. Deployment of this novel App improved participation over a daily question-answer e-mail format, and answers correlated with standardized test performance. The effect of the App on overall education is unclear, and a multi-institutional study has been initiated. Copyright © 2015 Association of Program Directors in Surgery. All

  15. Bacteriophage Applications for Food Production and Processing. (United States)

    Moye, Zachary D; Woolston, Joelle; Sulakvelidze, Alexander


    Foodborne illnesses remain a major cause of hospitalization and death worldwide despite many advances in food sanitation techniques and pathogen surveillance. Traditional antimicrobial methods, such as pasteurization, high pressure processing, irradiation, and chemical disinfectants are capable of reducing microbial populations in foods to varying degrees, but they also have considerable drawbacks, such as a large initial investment, potential damage to processing equipment due to their corrosive nature, and a deleterious impact on organoleptic qualities (and possibly the nutritional value) of foods. Perhaps most importantly, these decontamination strategies kill indiscriminately, including many—often beneficial—bacteria that are naturally present in foods. One promising technique that addresses several of these shortcomings is bacteriophage biocontrol, a green and natural method that uses lytic bacteriophages isolated from the environment to specifically target pathogenic bacteria and eliminate them from (or significantly reduce their levels in) foods. Since the initial conception of using bacteriophages on foods, a substantial number of research reports have described the use of bacteriophage biocontrol to target a variety of bacterial pathogens in various foods, ranging from ready-to-eat deli meats to fresh fruits and vegetables, and the number of commercially available products containing bacteriophages approved for use in food safety applications has also been steadily increasing. Though some challenges remain, bacteriophage biocontrol is increasingly recognized as an attractive modality in our arsenal of tools for safely and naturally eliminating pathogenic bacteria from foods.

    Purucker, S.T.; Lyon, B.F. [Oak Ridge National Lab., TN (United States). Risk Analysis Section]|[Univ. of Tennessee, Knoxville, TN (United States)


    Quantitative decision methods can be developed during environmental restoration projects that incorporate stakeholder input and can complement current efforts that are undertaken for data collection and alternatives evaluation during the CERCLA process. These decision-making tools can supplement current EPA guidance as well as focus on problems that arise as attempts are made to make informed decisions regarding remedial alternative selection. In examining the use of such applications, the authors discuss the use of decision analysis tools and their impact on collecting data and making environmental decisions from a risk-based perspective. They will look at the construction of objective functions for quantifying different risk-based perspective. They will look at the construction of objective functions for quantifying different risk-based decision rules that incorporate stakeholder concerns. This represents a quantitative method for implementing the Data Quality Objective (DQO) process. These objective functions can be expressed using a variety of indices to analyze problems that currently arise in the environmental field. Examples include cost, magnitude of risk, efficiency, and probability of success or failure. Based on such defined objective functions, a project can evaluate the impact of different risk and decision selection strategies on data worth and alternative selection.

  17. Rapid bioremediation processes: Theory and application

    International Nuclear Information System (INIS)

    Autry, A.R.; Shearon, M.S.; Archer, B.


    Bioremediation generally involves stimulating microorganisms (bacteria and fungi) to grow and in the process of growth, degrade hazardous waste. A variety of contaminant compounds can be readily biodegraded by both pure cultures of bacteria and by bacteria under field conditions. These compounds include petroleum and its distillates (gasoline, diesel fuel, etc.), aromatic hydrocarbons (BTEX and PAHS), PCBs (most congeners), chlorinated aeromatics (TCE and dichloroethane) and chlorinated aromatics (polychlorophenols and chlorobenzene). While the metabolic pathways for biodegradation are fairly distinct for each class of contaminants, the pathways generally converge on a central metabolite, acetyl-CoA, which can then be directly converted to CO 2 or microbial biomass. Organic compounds are most rapidly degraded aerobically. SafeSoil is a proprietary additive and biotreatment process. The additive contains inorganic nutrients (primarily N and P) and organic nutrients (simple sugars, protein and more complex cometabolites) which, upon addition to soil, stimulate natural microbial (primarily bacterial) populations to grow and degrade the contaminants of interest. Field applications of SafeSoil at Channel Gateway Development Project in Marina del Rey, California, validated that the SafeSoil treatment process effectively reduced TPH and BTEX concentrations for petroleum-contaminated soils to below action levels in as few as 4 days; the median curing time was 14 days. Longer chain hydrocarbons required more time, up to 36 days for TPH. Aerobic soil bacterial populations increased up to five-fold in response to treatment and returned to near pretreatment levels soon after the contaminant level was depleted. Volatilization of organics was measured and was found to be insignificant when compared to the total contaminant load indicating that the majority of the hydrocarbon contaminants were removed by biological means

      Given their key position in the process control industry, process monitoring techniques have been extensively investigated by industrial practitioners and academic control researchers. Multivariate statistical process control (MSPC) is one of the most popular data-based methods for process monitoring and is widely used in various industrial areas. Effective routines for process monitoring can help operators run industrial processes efficiently at the same time as maintaining high product quality. Multivariate Statistical Process Control reviews the developments and improvements that have been made to MSPC over the last decade, and goes on to propose a series of new MSPC-based approaches for complex process monitoring. These new methods are demonstrated in several case studies from the chemical, biological, and semiconductor industrial areas.   Control and process engineers, and academic researchers in the process monitoring, process control and fault detection and isolation (FDI) disciplines will be inter...

  20. Comparison of two different approaches for the application of the mini nutritional assessment in nursing homes: resident interviews versus assessment by nursing staff. (United States)

    Kaiser, R; Winning, K; Uter, W; Lesser, S; Stehle, P; Sieber, C C; Bauer, J M


    When the Mini Nutritional Assessment (MNA) was developed, the authors did not specifically focus on the nursing home setting. Due to a number of particularities of nursing home residents, such as cognitive and linguistic disabilities, a number of uncertainties with regard to its application await clarification. The aim of this study was to compare the results of two different modes of MNA application in nursing homes: resident interviews versus assessment by nursing staff. The MNA was applied to 200 residents of two municipal nursing homes in Nuremberg, Germany. First one-on-one interviews of the residents were conducted by two researchers from our group. Next, the MNA was applied by the attending nursing staff who was blinded to the results of the first MNA. To evaluate the prognostic properties of the two different approaches, data on mortality of the screened residents were collected during a six-month follow-up period. Among 200 residents (f 147 m 53, f 86.5 +/- 7.4 y. m 83.0 +/- 8.5 y.), the MNA could be applied to 138 residents (69.0%) by one-on-one interviews and to 188 residents (94.0%) by the nursing staff. 15.2% of the residents were categorised as malnourished by the interviews and 8.7% by the nursing staff's assessment. The agreement of the two forms was low for the MNA short form (weighted kappa = 0.31; 95% CI: 0.14 - 0.47) as well as for the full MNA (weighted kappa = 0.35; 95% CI: 0.27 - 0.44). After exclusion of residents with cognitive impairment (n=89), agreement for the full version increased (weighted kappa = 0.47, 95% CI 0.25 - 0.68). 25 (12.5%) study participants deceased during the follow-up period. Mortality was significantly associated with the mortality for both approaches, while the MNA application by the nursing staff proved to be superior (nursing staff p application rate is higher and interference with cognitive as well as linguistic deficits is lower. In future studies, the mode of MNA application in nursing home residents should be

    Kluge, Mary Ann; LeCompte, Michelle; Ramel, Lisa


    This study's mixed-methods design sought to understand how to encourage assisted-living (AL) residents to initiate and continue exercise in a gym setting. Ten residents participated in this yearlong program. Processes developed and perceived benefits were understood through interviews and observations. Changes in active time, lower body strength, and workload were evaluated using direct measures. Findings indicated that AL residents regularly used exercise machines (mean participation = 53.8%) and increased active time and lower body strength (p = .02) when adequately prepared and supported. Participants prioritized gym time and developed pride and ownership in the program. They described themselves as exercisers and developed a sense of belonging to their new home. Friendships with one another, staff, and university partners were nurtured in the gym setting. When provided space, equipment, trained staff, and additional resource support, AL residents' quality of life and life satisfaction were enhanced in several domains.

  3. Vascular Wall-Resident Multipotent Stem Cells of Mesenchymal Nature within the Process of Vascular Remodeling: Cellular Basis, Clinical Relevance, and Implications for Stem Cell Therapy

    Directory of Open Access Journals (Sweden)

    Diana Klein


    Full Text Available Until some years ago, the bone marrow and the endothelial cell compartment lining the vessel lumen (subendothelial space were thought to be the only sources providing vascular progenitor cells. Now, the vessel wall, in particular, the vascular adventitia, has been established as a niche for different types of stem and progenitor cells with the capacity to differentiate into both vascular and nonvascular cells. Herein, vascular wall-resident multipotent stem cells of mesenchymal nature (VW-MPSCs have gained importance because of their large range of differentiation in combination with their distribution throughout the postnatal organism which is related to their existence in the adventitial niche, respectively. In general, mesenchymal stem cells, also designated as mesenchymal stromal cells (MSCs, contribute to the maintenance of organ integrity by their ability to replace defunct cells or secrete cytokines locally and thus support repair and healing processes of the affected tissues. This review will focus on the central role of VW-MPSCs within vascular reconstructing processes (vascular remodeling which are absolute prerequisite to preserve the sensitive relationship between resilience and stability of the vessel wall. Further, a particular advantage for the therapeutic application of VW-MPSCs for improving vascular function or preventing vascular damage will be discussed.

    Chen, Qun; Finney, Karen; Li, Hanning; Zhang, Xiaohui; Zhou, Jue; Sharifi, Vida; Swithenbank, Jim


    Major challenging issues such as climate change, energy prices and fuel security have focussed the attention of process industries on their energy efficiency and opportunities for improvement. The main objective of this research study was to investigate technologies needed to exploit the large amount of low grade heat available from a flue gas condensing system through industrial condensing boilers. The technology and application of industrial condensing boilers in various heating systems were extensively reviewed. As the condensers require site-specific engineering design, a case study was carried out to investigate the feasibility (technically and economically) of applying condensing boilers in a large scale district heating system (40 MW). The study showed that by recovering the latent heat of water vapour in the flue gas through condensing boilers, the whole heating system could achieve significantly higher efficiency levels than conventional boilers. In addition to waste heat recovery, condensing boilers can also be optimised for emission abatement, especially for particle removal. Two technical barriers for the condensing boiler application are corrosion and return water temperatures. Highly corrosion-resistant material is required for condensing boiler manufacture. The thermal design of a 'case study' single pass shell-and-tube condensing heat exchanger/condenser showed that a considerable amount of thermal resistance was on the shell-side. Based on the case study calculations, approximately 4900 m 2 of total heat transfer area was required, if stainless steel was used as a construction material. If the heat transfer area was made of carbon steel, then polypropylene could be used as the corrosion-resistant coating material outside the tubes. The addition of polypropylene coating increased the tube wall thermal resistance, hence the required heat transfer area was approximately 5800 m 2 . Net Present Value (NPV) calculations showed that the choice of a carbon

    Warnakulasuriya, Tania; Williams, Senani; Dabarera, Mangala; Rodrigo, Kusum; Weerakkody, Thiwanka; Wickremasinghe, Rajitha


    Lanka Mineral Sands Ltd (LMS), a government-owned company, has been mining mineral sands including monazite which contains thorium (Th) at Pulmoddai, Sri Lanka since 1957. Th emits alpha particles on decay and gamma rays are emitted by the daughter products. The cytokinesis-blocked micronucleus (MN) assay is popular for large scale radiation exposure studies as it is an easy, fast and reliable method of biodosimetry. The objective of the study was to determine the frequency of micronuclei among persons residing in the vicinity of LMS. A cross-sectional study was conducted from November 2012 to September 2016 among persons 35-45 years of age to evaluate the frequency of micronuclei in peripheral blood lymphocytes. Fifty-three employees of LMS factory, 25 residents within 5 km from LMS, 25 residents 20-25 km from LMS and 29 residents from >50 km away from LMS were included in the study. The highest median frequency of micronuclei per 1000 binucleated (BN) cells was in the group residing within 5 km from LMS with a median (IQ range) of 0.67 (0.17-2.17). The median (IQ range) of MN frequency of employees of LMS, residents 20-25 km from LMS and residents >50 km from LMS were 0.66 (0.16-1.16), 0.33 (0.00-0.67) and 0.33 (0.33-0.67), respectively. There was no significant difference in the MN frequency between employees of LMS and the group residing within 5 km from LMS. Being a resident of Pulmoddai and being exposed to X-rays were significant predictors of MN frequency. Persons residing within 5 km from LMS had a higher risk of MN formation irrespective of being employed at LMS. © The Author 2017.

  7. Increasing Competitiveness for an Otolaryngology Residency: Where We Are and Concerns about the Future. (United States)

    Kaplan, Alyson B; Riedy, Katherine N; Grundfast, Kenneth M


    For graduating medical students, securing a residency in otolaryngology-head and neck surgery has become exceedingly difficult. This commentary explores the ways that applicants and residency programs are reacting to the increasing competitiveness in applying to, interviewing for, and matching to an otolaryngology residency. The commonly held perceptions of applicants are compared to perspectives held by residency program directors and resident selection committees. Unintended consequences of the growing trend for medical students to add a research year to their curriculum are presented. Some cautions and suggestions about how to improve the application and selection process are offered. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

  9. On some applications of diffusion processes for image processing

    Energy Technology Data Exchange (ETDEWEB)

    Morfu, S., E-mail: smorfu@u-bourgogne.f [Laboratoire d' Electronique, Informatique et Image (LE2i), UMR Cnrs 5158, Aile des Sciences de l' Ingenieur, BP 47870, 21078 Dijon Cedex (France)


    We propose a new algorithm inspired by the properties of diffusion processes for image filtering. We show that purely nonlinear diffusion processes ruled by Fisher equation allows contrast enhancement and noise filtering, but involves a blurry image. By contrast, anisotropic diffusion, described by Perona and Malik algorithm, allows noise filtering and preserves the edges. We show that combining the properties of anisotropic diffusion with those of nonlinear diffusion provides a better processing tool which enables noise filtering, contrast enhancement and edge preserving.

  10. Rapid thermal processing and beyond applications in semiconductor processing

    CERN Document Server

    Lerch, W


    Heat-treatment and thermal annealing are very common processing steps which have been employed during semiconductor manufacturing right from the beginning of integrated circuit technology. In order to minimize undesired diffusion, and other thermal budget-dependent effects, the trend has been to reduce the annealing time sharply by switching from standard furnace batch-processing (involving several hours or even days), to rapid thermal processing involving soaking times of just a few seconds. This transition from thermal equilibrium, to highly non-equilibrium, processing was very challenging a

  11. The surgical experience of general surgery residents: an analysis of the applicability of the specialty program in General and Digestive Surgery. (United States)

    Targarona Soler, Eduardo Ma; Jover Navalon, Jose Ma; Gutierrez Saiz, Javier; Turrado Rodríguez, Víctor; Parrilla Paricio, Pascual


    Residents in our country have achieved a homogenous surgical training by following a structured residency program. This is due to the existence of specific training programs for each specialty. The current program, approved in 2007, has a detailed list of procedures that a surgeon should have performed in order to complete training. The aim of this study is to analyze the applicability of the program with regard to the number of procedures performed during the residency period. A data collection form was designed that included the list of procedures from the program of the specialty; it was sent in April 2014 to all hospitals with accredited residency programs. In September 2014 the forms were analysed, and a general descriptive study was performed; a subanalysis according to the resident's sex and Autonomous region was also performed. The number of procedures performed according to the number of residents in the different centers was also analyzed. The survey was sent to 117 hospitals with accredited programs, which included 190 resident places. A total of 91 hospitals responded (53%). The training offered adapts in general to the specialty program. The total number of procedures performed in the different sub-areas, in laparoscopic and emergency surgery is correct or above the number recommended by the program, with the exception of esophageal-gastric and hepatobiliary surgery. The sub-analysis according to Autonomous region did not show any significant differences in the total number of procedures, however, there were significant differences in endocrine surgery (P=.001) and breast surgery (P=.042). A total of 55% of residents are female, with no significant differences in distribution in Autonomous regions. However, female surgeons operate more than their male counterparts during the residency period (512±226 vs. 625±244; P<.01). The number of residents in the hospital correlates with the number of procedures performed; the residents with more procedures

  12. Chemometrics applications in biotech processes: assessing process comparability. (United States)

    Bhushan, Nitish; Hadpe, Sandip; Rathore, Anurag S


    A typical biotech process starts with the vial of the cell bank, ends with the final product and has anywhere from 15 to 30 unit operations in series. The total number of process variables (input and output parameters) and other variables (raw materials) can add up to several hundred variables. As the manufacturing process is widely accepted to have significant impact on the quality of the product, the regulatory agencies require an assessment of process comparability across different phases of manufacturing (Phase I vs. Phase II vs. Phase III vs. Commercial) as well as other key activities during product commercialization (process scale-up, technology transfer, and process improvement). However, assessing comparability for a process with such a large number of variables is nontrivial and often companies resort to qualitative comparisons. In this article, we present a quantitative approach for assessing process comparability via use of chemometrics. To our knowledge this is the first time that such an approach has been published for biotech processing. The approach has been applied to an industrial case study involving evaluation of two processes that are being used for commercial manufacturing of a major biosimilar product. It has been demonstrated that the proposed approach is able to successfully identify the unit operations in the two processes that are operating differently. We expect this approach, which can also be applied toward assessing product comparability, to be of great use to both the regulators and the industry which otherwise struggle to assess comparability.

  18. An international comparison of the Ohio department of aging-resident satisfaction survey: applicability in a U.S. and Canadian sample. (United States)

    Cooke, Heather A; Yamashita, Takashi; Brown, J Scott; Straker, Jane K; Baiton Wilkinson, Susan


    The majority of resident satisfaction surveys available for use in assisted living settings have been developed in the United States; however, empirical assessment of their measurement properties remains limited and sporadic, as does knowledge regarding their applicability for use in settings outside of the United States. This study further examines the psychometric properties of the Ohio Department of Aging-Resident Satisfaction Survey (ODA-RSS) and explores its applicability within a sample of Canadian assisted living facilities. Data were collected from 9,739 residential care facility (RCF) residents in Ohio, United States and 938 assisted-living residents in British Columbia, Canada. Confirmatory factor analysis was used to assess the instrument's psychometric properties within the 2 samples. Although the ODA-RSS appears well suited for assessing resident satisfaction in Ohio RCFs, it is less so in British Columbia assisted living settings. Adequate reliability and validity were observed for all 8 measurable instrument domains in the Ohio sample, but only 4 (Care and Services, Employee Relations, Employee Responsiveness, and Communications) in the British Columbia sample. The ODA-RSS performs best in an environment that encompasses a wide range of RCF types. In settings where greater uniformity and standardization exist, more nuanced questions may be required to detect variation between facilities. It is not sufficient to assume that rigorous development and empirical testing of a tool ensures its applicability in states or countries other than that in which it was initially developed.

  4. Associations between flame retardant applications in furniture foam, house dust levels, and residents' serum levels. (United States)

    Hammel, Stephanie C; Hoffman, Kate; Lorenzo, Amelia M; Chen, Albert; Phillips, Allison L; Butt, Craig M; Sosa, Julie Ann; Webster, Thomas F; Stapleton, Heather M


    Polyurethane foam (PUF) in upholstered furniture frequently is treated with flame retardant chemicals (FRs) to reduce its flammability and adhere to rigorous flammability standards. For decades, a commercial mixture of polybrominated diphenyl ethers (PBDEs) called PentaBDE was commonly applied to foam to fulfill these regulations; however, concerns over toxicity, bioaccumulation, and persistence led to a global phase-out in the mid-2000s. Although PentaBDE is still detected in older furniture, other FR compounds such as tris(1,3-dichloroisopropyl) phosphate (TDCIPP) and Firemaster® 550 (FM550) have been increasingly used as replacements. While biomonitoring studies suggest exposure is widespread, the primary sources of exposure are not clearly known. Here, we investigated the relationships between specific FR applications in furniture foam and human exposure. Paired samples of furniture foam, house dust and serum samples were collected from a cohort in North Carolina, USA and analyzed for FRs typically used in PUF. In general, the presence of a specific FR in the sofa of a home was associated with an increase in the concentration of that FR in house dust. For example, the presence of PentaBDE in sofas was associated with significantly higher levels of BDE-47, a major component of PentaBDE, in house dust (10 β =6.4, p<0.001). A similar association was observed with a component of FM550, 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB), with levels that were approximately 3 times higher in house dust when FM550 was identified in the sofa foam (p<0.01). These relationships were modified by dust loading rates in the living room and the ratio of sofa size to room size. Interestingly, levels of TDCIPP and tris(1-chloro-2-isopropyl) phosphate (TCIPP) were also higher in dust with detections in sofa foam; however, these associations were not statistically significant and may suggest there are other prominent sources of these compounds in the home. In addition, the

  7. Practical Applications for Maintenance of Certification Products in Child and Adolescent Residency Training. (United States)

    Williams, Laurel L; Sexson, Sandra; Dingle, Arden D; Young-Walker, Laine; John, Nadyah; Hunt, Jeffrey


    The authors evaluated whether Maintenance of Certification (MOC) Performance-in-Practice products in training increases trainee knowledge of MOC processes and is viewed by trainees as a useful activity. Six child and adolescent psychiatry fellowships used MOC products in continuity clinics to assess their usefulness as training tools. Two surveys assessed initial knowledge of MOC and usefulness of the activity. Forty-one fellows completed the initial survey. A majority of first-year fellows indicated lack of awareness of MOC in contrast to a majority of second-year fellows who indicated some awareness. Thirty-five fellows completed the second survey. A majority of first- and second-year fellows found the activity easy to execute and would change something about their practice as a result. Using MOC products in training appears to be a useful activity that may assist training programs in teaching the principles of self- and peer-learning.

  8. Applications of Biocatalysis to Industrial Processes (United States)

    Sime, John T.


    Enzyme-catalyzed chemistry (biocatalysis) is widely used across many industry sectors in large-scale processes. The possibility of environmentally friendly chemical reactions carried out under mild conditions with high degrees of selectivity has proved attractive in developing manufacturing processes. A number of such reactions are discussed in the industrial context with examples of a variety of reaction types. All processes presented have been implemented in the production of commercial products and provide a feel for the versatility of this technology.


    Land application of sewage sludge generated by domestic sewage treatment is performed in an environmentally safe and cost–effective manner in many communities. Land application involves taking advantage of the fertilizing and soil conditioning properties of sewage sludge by spreading the sewage sludge on the soil surface, incorporating or injecting the sewage sludge into soil, or spraying the sewage sludge. Because sewage sludge disposal practices (e.g., landfilling) are becoming less available and more costly, and because of the increasing desire to beneficially reuse waste residuals whenever possible, land application is increasingly chosen as a sewage sludge use or disposal practice. Approximately 33 percent of the 5.4 million dry metric tons of sewage sludge generated annually in the United States at publicly owned treatment works (POTWs) is land applied. Of the sewage sludge that is land applied, approximately 67% is land applied on agricultural lands, 3% on forest lands, approximately 9% on reclamation sites, and 9% on public contact sites; 12% is sold or given away in a bag or other container for application to the land (Federal Register, Vol. 58, No. 32, February 19, 1993). In addition, approximately 8.6 billion gallons of domestic septage is generated annually. Land application of sewage sludge has been practiced in many countries for centuries so that the nutrients (e.g., nitrogen, phosphorus) and organic matter in sewage sludge can be beneficia

  10. How Useful are Orthopedic Surgery Residency Web Pages? (United States)

    Oladeji, Lasun O; Yu, Jonathan C; Oladeji, Afolayan K; Ponce, Brent A


    Medical students interested in orthopedic surgery residency positions frequently use the Internet as a modality to gather information about individual residency programs. Students often invest a painstaking amount of time and effort in determining programs that they are interested in, and the Internet is central to this process. Numerous studies have concluded that program websites are a valuable resource for residency and fellowship applicants. The purpose of the present study was to provide an update on the web pages of academic orthopedic surgery departments in the United States and to rate their utility in providing information on quality of education, faculty and resident information, environment, and applicant information. We reviewed existing websites for the 156 departments or divisions of orthopedic surgery that are currently accredited for resident education by the Accreditation Council for Graduate Medical Education. Each website was assessed for quality of information regarding quality of education, faculty and resident information, environment, and applicant information. We noted that 152 of the 156 departments (97%) had functioning websites that could be accessed. There was high variability regarding the comprehensiveness of orthopedic residency websites. Most of the orthopedic websites provided information on conference, didactics, and resident rotations. Less than 50% of programs provided information on resident call schedules, resident or faculty research and publications, resident hometowns, or resident salary. There is a lack of consistency regarding the content presented on orthopedic residency websites. As the competition for orthopedic websites continues to increase, applicants flock to the Internet to learn more about orthopedic websites in greater number. A well-constructed website has the potential to increase the caliber of students applying to a said program. Copyright © 2015 Association of Program Directors in Surgery. Published by

    Screening, brief intervention, and referral to treatment (SBIRT), an evidence-based validated system for providing early detection and brief treatment of substance use disorders, has been widely used in the training of medical residents across specialties at a number of sites. This article investigates the effectiveness of SBIRT training during short-term follow-up at Albany Medical Center, one of the initial Substance Abuse and Mental Health Services Administration (SAMHSA) grantees. Training outcomes were measured by training satisfaction following opportunities to apply SBIRT skills in clinical work, the rate at which these techniques were applied in clinical work, and the degree to which residents felt that the SBIRT training provided skills that were applicable to their practice. We examined differences in learning experience by postgraduate year and by program, and conducted a qualitative analysis in a convergent parallel mixed-methods design to elucidate barriers encountered by residents upon using SBIRT techniques in clinical practice. Residents remained highly satisfied with the training at 4-month follow-up, with 80.1% reporting that they had used SBIRT skills in their clinical work. Use of SBIRT techniques was high at 6-month follow-up as well, with 85.9% of residents reporting that they regularly screened their patients for substance use, 74.4% reporting that they had applied brief intervention techniques, and 78.2% indicating that SBIRT training had made them overall more effective in helping patients with substance use issues. Differences in application rates and satisfaction were found by specialty. Qualitative analyses indicated that residents encountered patient readiness and specific contextual factors, such as time constraints, externally imposed values, and clinical norms, as barriers to implementation. Despite encountering obstacles such as time constraints and patient readiness, residents utilized many of the skills they had learned during

  14. Incorporating Interpersonal Skills into Otolaryngology Resident Selection and Training. (United States)

    Lu-Myers, Yemeng; Myers, Christopher G


    Increasing attention has been paid to the selection of otolaryngology residents, a highly competitive process but one with room for improvement. A recent commentary in this journal recommended that residency programs more thoroughly incorporate theory and evidence from personnel psychology (part of the broader field of organizational science) in the resident selection process. However, the focus of this recommendation was limited to applicants' cognitive abilities and independent work-oriented traits (eg, conscientiousness). We broaden this perspective to consider critical interpersonal skills and traits that enhance resident effectiveness in interdependent health care organizations and we expand beyond the emphasis on selection to consider how these skills can be honed during residency. We advocate for greater use of standardized team-based care simulations, which can aid in assessing and developing the key interpersonal leadership skills necessary for success as an otolaryngology resident.

  2. Application of membrane technologies for liquid radioactive waste processing

    International Nuclear Information System (INIS)


    Membrane separation processes have made impressive progress since the first synthesis of membranes almost 40 years ago. This progress was driven by strong technological needs and commercial expectations. As a result the range of successful applications of membranes and membrane processes is continuously broadening. In addition, increasing application of membrane processes and technologies lies in the increasing variations of the nature and characteristics of commercial membranes and membrane apparatus. The objective of the report is to review the information on application of membrane technologies in the processing of liquid radioactive waste. The report covers the various types of membranes, equipment design, range of applications, operational experience and the performance characteristics of different membrane processes. The report aims to provide Member States with basic information on the applicability and limitations of membrane separation technologies for processing liquid radioactive waste streams

  3. Personality Testing May Improve Resident Selection in Anesthesiology Programs (United States)

    Merlo, Lisa J.; Matveevskii, Alexander S.


    Background Current methods of selecting future residents for anesthesiology training programs do not adequately distinguish those who will succeed from the pool of seemingly well-qualified applicants. Some residents, despite high exam scores, may struggle in the OR in stressful situations. Aims This study examined whether specific neuropsychological and personality measures can distinguish high competency residents from low competency residents to aid in resident selection. Methods 25 residents enrolled in an anesthesiology program at a major academic institution were identified for participation. 13 were evaluated identified as “high competency” residents and 12 as “low competency ” by the department's clinical competency committee. Groups were evaluated on measures of fine motor dexterity, executive functioning, processing speed, attention, and personality using IPIP-NEO. Results There were no significant differences between groups on measures of fine-motor dexterity, executive functioning, processing speed, or attention. High competency residents scored significantly higher than low competency residents on measures of cooperation, self-efficacy, and adventurousness, and lower on measures of neuroticism, anxiety, anger, and vulnerability. Conclusion Although measures of fine-motor dexterity, executive functioning, processing speed, and attention do not appear to distinguish between high- and low competency residents in anesthesiology, specific personality characteristics may be associated with future success in an anesthesiology training program.

    Grycová Barbora


    Full Text Available The food industry produces large amounts of solid and also liquid wastes. Different waste materials and their mixtures were pyrolysed in the laboratory pyrolysis unit to a final temperature of 800°C with a 10 minute delay at the final temperature. After the pyrolysis process of the selected wastes a mass balance of the resulting products, off-line analysis of the pyrolysis gas and evaluation of solid and liquid products were carried out. The highest concentration of methane, hydrogen and carbon monoxide were analyzed during the 4th gas sampling at a temperature of approx. 720–780°C. The concentration of hydrogen was measured in the range from 22 to 40 vol.%. The resulting iodine numbers of samples CHFO, DS, DSFW reach values that indicate the possibility of using them to produce the so-called “disposable sorbents” in wastewater treatment. The WC condensate can be directed to further processing and upgrading for energy use.

  7. Positive trigonometric polynomials and signal processing applications

    CERN Document Server

    Dumitrescu, Bogdan


    This revised edition is made up of two parts: theory and applications. Though many of the fundamental results are still valid and used, new and revised material is woven throughout the text. As with the original book, the theory of sum-of-squares trigonometric polynomials is presented unitarily based on the concept of Gram matrix (extended to Gram pair or Gram set). The programming environment has also evolved, and the books examples are changed accordingly. The applications section is organized as a collection of related problems that use systematically the theoretical results. All the problems are brought to a semi-definite programming form, ready to be solved with algorithms freely available, like those from the libraries SeDuMi, CVX and Pos3Poly. A new chapter discusses applications in super-resolution theory, where Bounded Real Lemma for trigonometric polynomials is an important tool. This revision is written to be more appealing and easier to use for new readers. < Features updated information on LMI...

  11. Fluorine disposal processes for nuclear applications

    Energy Technology Data Exchange (ETDEWEB)

    Netzer, W.D.


    A study was performed to determine the best method for disposing of waste fluorine in the effluent from a uranium oxide conversion facility. After reviewing the fluorine disposal literature and upon considering the nuclear safety constraints, it was determined that the two most promising processes were the fluidized alumina bed and the caustic scrubber. To obtain more design data for the latter process, a 3-stage, 5-in. I.D. spray tower was constructed and operated. This unit used a 10% potassium hydroxide solution at flows of 1.5 to 3 gpm and achieved a 90% fluorine efficiency at fluorine flowrates as high as 4 scfm. However, two toxic by-products, oxygen difluoride and nitroxy fluoride, were detected in the effluent gases. After considering the relative merits of both disposal processes, it is concluded that the fluidized bed is superior, especially if the contaminated waste material were salable.

    Residency applicants have the right to see letters of recommendation written on their behalf. It is not known whether applicants are affected by waiving this right. Our multicenter study assessed how frequently residency applicants waived their FERPA rights to view their letters of recommendation, and whether this affected the ratings they were given by faculty. We reviewed all ERAS-submitted letters of recommendation to 14 ACGME-accredited programs in 2006-2007. We collected ERAS ID, program name, FERPA declaration, standardized letter of recommendation (SLOR) use, and SLOR Global Assessment ranking. The percentage of applicants who waived their FERPA rights was determined. Chi-square tests of independence assessed whether applicants' decision to waive their FERPA rights was associated with their SLOR Global Assessment. We examined 1776 applications containing 6424 letters of recommendations. Of 2736 letters that specified a Global Assessment, 2550 (93%) applicants waived their FERPA rights, while 186 did not. Of the applicants who chose not to waive their rights, 45.6% received a ranking of Outstanding, 35.5% Excellent, 18.3% Very Good, and 1.6% Good. Of applicants who waived their FERPA rights, 35.1% received a ranking of Outstanding, 49.6% Excellent, 13.7% Very Good, and 1.6% Good. Applicants who did not waive their FERPA rights were more likely to receive an Outstanding Assessment (P  =  .003). The majority (93%) of residency applicants waived their FERPA rights. Those who did not waive their rights had a statistically higher chance of receiving an Outstanding Assessment than those who did.

  14. Applications of molten salts in plutonium processing

    International Nuclear Information System (INIS)

    Bowersox, D.F.; Christensen, D.C.; Williams, J.D.


    Plutonium is efficiently recovered from scrap at Los Alamos by a series of chemical reactions and separations conducted at temperatures ranging from 700 to 900 0 C. These processes usually employ a molten salt or salt eutectic as a heat sink and/or reaction medium. Salts for these operations were selected early in the development cycle. The selection criteria are being reevaluated. In this article we describe the processes now in use at Los Alamos and our studies of alternate salts and eutectics

  15. A process evaluation of a Psychomotor Dance Therapy Intervention (DANCIN) for behavior change in dementia: attitudes and beliefs of participating residents and staff. (United States)

    Guzmán, Azucena; Robinson, Lisa; Rochester, Lynn; James, Ian A; Hughes, Julian C


    In a previous paper, we presented results from a 12-week study of a Psychomotor DANCe Therapy INtervention (DANCIN) based on Danzón Latin Ballroom that involves motor, emotional-affective, and cognitive domains, using a multiple-baseline single-case design in three care homes. This paper reports the results of a complementary process evaluation to elicit the attitudes and beliefs of home care staff, participating residents, and family members with the aim of refining the content of DANCIN in dementia care. An external researcher collected bespoke questionnaires from ten participating residents, 32 care home staff, and three participants' family members who provided impromptu feedback in one of the care homes. The Behavior Change Technique Taxonomy v1 (BCTTv1) provided a methodological tool for identifying active components of the DANCIN approach warranting further exploration, development, and implementation. Ten residents found DANCIN beneficial in terms of mood and socialization in the care home. Overall, 78% of the staff thought DANCIN led to improvements in residents' mood; 75% agreed that there were improvements in behavior; 56% reported increased job satisfaction; 78% of staff were enthusiastic about receiving further training. Based on participants' responses, four BCTTv1 labels-Social support (emotional), Focus on past success and verbal persuasion to boost self-efficacy, Restructuring the social environment and Habit formation-were identified to describe the intervention. Residents and staff recommended including additional musical genres and extending the session length. Discussions of implementing a supervision system to sustain DANCIN regularly regardless of management or staff turnover were suggested. Care home residents with mild to moderate dementia wanted to continue DANCIN as part of their routine care and staff and family members were largely supportive of this approach. This study argues in favor of further dissemination of DANCIN in care homes

  18. Computational Fluid Dynamics - Applications in Manufacturing Processes (United States)

    Beninati, Maria Laura; Kathol, Austin; Ziemian, Constance


    A new Computational Fluid Dynamics (CFD) exercise has been developed for the undergraduate introductory fluid mechanics course at Bucknell University. The goal is to develop a computational exercise that students complete which links the manufacturing processes course and the concurrent fluid mechanics course in a way that reinforces the concepts in both. In general, CFD is used as a tool to increase student understanding of the fundamentals in a virtual world. A ``learning factory,'' which is currently in development at Bucknell seeks to use the laboratory as a means to link courses that previously seemed to have little correlation at first glance. A large part of the manufacturing processes course is a project using an injection molding machine. The flow of pressurized molten polyurethane into the mold cavity can also be an example of fluid motion (a jet of liquid hitting a plate) that is applied in manufacturing. The students will run a CFD process that captures this flow using their virtual mold created with a graphics package, such as SolidWorks. The laboratory structure is currently being implemented and analyzed as a part of the ``learning factory''. Lastly, a survey taken before and after the CFD exercise demonstrate a better understanding of both the CFD and manufacturing process.

  20. Dynamic Magnetic Field Applications for Materials Processing (United States)

    Mazuruk, K.; Grugel, Richard N.; Motakef, S.; Whitaker, Ann F. (Technical Monitor)


    Magnetic fields, variable in time and space, can be used to control convection in electrically conducting melts. Flow induced by these fields has been found to be beneficial for crystal growth applications. It allows increased crystal growth rates, and improves homogeneity and quality. Particularly beneficial is the natural convection damping capability of alternating magnetic fields. One well-known example is the rotating magnetic field (RMF) configuration. RMF induces liquid motion consisting of a swirling basic flow and a meridional secondary flow. In addition to crystal growth applications, RMF can also be used for mixing non-homogeneous melts in continuous metal castings. These applied aspects have stimulated increasing research on RMF-induced fluid dynamics. A novel type of magnetic field configuration consisting of an axisymmetric magnetostatic wave, designated the traveling magnetic field (TMF), has been recently proposed. It induces a basic flow in the form of a single vortex. TMF may find use in crystal growth techniques such as the vertical Bridgman (VB), float zone (FZ), and the traveling heater method. In this review, both methods, RMF and TMF are presented. Our recent theoretical and experimental results include such topics as localized TMF, natural convection dumping using TMF in a vertical Bridgman configuration, the traveling heater method, and the Lorentz force induced by TMF as a function of frequency. Experimentally, alloy mixing results, with and without applied TMF, will be presented. Finally, advantages of the traveling magnetic field, in comparison to the more mature rotating magnetic field method, will be discussed.

  2. Motivations and demographics of I-6 and traditional 5+2 cardiothoracic surgery resident applicants: insights from an academic training program. (United States)

    Varghese, Thomas K; Mokadam, Nahush A; Verrier, Edward D; Wallyce, Delloney; Wood, Douglas E


    The introduction of the integrated 6-year cardiothoracic surgery residency (I-6) has changed the training paradigm for future cardiothoracic surgeons. Increased interest in these programs emphasizes the need for an understanding of the applicant pool and of their differences from the traditional trainee (5+2). National trends (National Resident Matching Program data), objective (Electronic Residency Application Services documents, United States Medical Licensing Examination [USMLE] scores, transcripts) and subjective metrics (interviews, personal statements, and recommendation letters) were evaluated for invited applicants for I-6 and 5+2 positions in 2010, 2011, and 2012. Demographics and motivations for specialty selection were determined. Statistical analyses were performed with Student's t test for continuous variables and Fisher's exact test for categoric variables. The number of applicants completing the match for I-6 positions each year was as follows: 2010, 74 (49 United States [US]); 2011, 74 (53 US); 2012, 80 (59 US). The number completing the match for 5+2 positions was as follows: 2010, 93 (67 US); 2011, 87 (55 US); 2012, 90 (63 US). For I-6 positions we interviewed 9 candidates in 2010, 17 in 2011, and 16 in 2012; for the 5+2 program we interviewed 14 candidates in 2010, 17 in 2011, and 13 in 2012. Both groups had a similar percentage of female applicants, number of US medical graduates, additional degrees, and membership in Alpha Omega Alpha. The I-6 applicants were younger (mean age, 27.4 years), were less likely to take time off for research (43.5% vs 72.7%), were less published, and had higher surgery clinical honors and USMLE scores. The 5+2 applicants were less likely to have done a cardiothoracic medical school rotation and had done senior-level rotations on general thoracic during residency; yet, only 29.5% had done a senior level cardiac rotation. The most frequently cited motivation was a clinical encounter during a cardiothoracic rotation

    Polypropylene (PP) and biodegradable polymer (blend of poly ({epsilon}-caploracton) 30/polybutylenesuccynate 70), PHB02 were irradiated with an electron beam to improve processability for production of thin film and foam. The processability of the polymer was improved due to enhancement of melt strength with irradiation at the dose range between 10 and 100 kGy. Increase of melt strength is due to entanglement of branch structure formed by irradiation. Possibility of high-speed production of thin film and production of foam have been achieved by this process. The soil degradation test showed that biodegradable polymer film buried in the soil was almost entirely degraded (97%) after two months and completely degraded after two and a half months. In the case of foam samples, 65% degradation was achieved after four months. Radiation crosslinked water-soluble polymer form hydrogel, which absorb much water. The hydrogel prepared by irradiation of polymer in aqueous solution was applied as dressing for healing of wound. In order to evaluate the healing effect of the polyethylene oxide (PEO) hydrogel dressing, wounds formed on the back of marmots were covered by the hydrogel. The healing under the wet environment of the hydrogel dressing had three advantages, compared with that of gauze dressing, which gives a dry environment: (1) enhancement of healing rate, (2) facilitation for changing the dressing, i.e. the hydrogel can be peeled off without any damage to the regenerated skin surface, and (3) hydrogel dressing material does not remain stuck on the wound.

  6. Metrology Sampling Strategies for Process Monitoring Applications

    KAUST Repository

    Vincent, Tyrone L.


    Shrinking process windows in very large scale integration semiconductor manufacturing have already necessitated the development of control systems capable of addressing sub-lot-level variation. Within-wafer control is the next milestone in the evolution of advanced process control from lot-based and wafer-based control. In order to adequately comprehend and control within-wafer spatial variation, inline measurements must be performed at multiple locations across the wafer. At the same time, economic pressures prompt a reduction in metrology, for both capital and cycle-time reasons. This paper explores the use of modeling and minimum-variance prediction as a method to select the sites for measurement on each wafer. The models are developed using the standard statistical tools of principle component analysis and canonical correlation analysis. The proposed selection method is validated using real manufacturing data, and results indicate that it is possible to significantly reduce the number of measurements with little loss in the information obtained for the process control systems. © 2011 IEEE.

  7. [Application of a cooperative learning approach for training residents in the emergency department and comparison with a traditional approach]. (United States)

    Guillén Astete, Carlos Antonio; de la Casa Resino, Cristina; Lucica Boteanu, Alina; Blázquez Cañamero, María de Los Ángeles; Braña Cardeñosa, Adela Florinda


    To analyze the benefits of using a cooperative learning (CL) model to teach hospital residents doing rotations in the emergency department and to compare the CL approach to traditional training. Two training sessions on the same content were given by 2 expert instructors. A traditional method of instruction was used in one of the sessions and the CL model was used in the other. Immediately after the sessions and 3 months later, the residents took a multiple-choice test that was developed by a third expert. A control group of residents who had not attended either session also took the test. Twenty-one residents were in the CL group and 17 were in the traditional-training group. The mean (SD) scores on the examinations immediately after training were 8.81 (1.40) and 7.88 (1.26), in the CL and traditional groups, respectively (P=.0414). Three months later, the mean scores of these same residents retaking the examination and 32 control residents were as follows: CL group, 8.19 (1.12); traditional group, 7.00 (1.22); and control group, 6.37 (1.37) (P.05, traditional vs control). The CL approach proved superior to traditional training in terms of short- and medium-term retention of information. Although this is the first analysis of CL in this type of specialized medical training, extending its use in preparing medical residents working in emergency departments would seem to be justified.

Finally, further development of the anammox engineering application is proposed in this review.

  13. Supercritical fluid technologies for ceramic-processing applications

    International Nuclear Information System (INIS)

    Matson, D.W.; Smith, R.D.


    This paper reports on the applications of supercritical fluid technologies for ceramic processing. The physical and chemical properties of these densified gases are summarized and related to their use as solvents and processing media. Several areas are identified in which specific ceramic processes benefit from the unique properties of supercritical fluids. The rapid expansion of supercritical fluid solutions provides a technique for producing fine uniform powders and thin films of widely varying materials. Supercritical drying technologies allow the formation of highly porous aerogel products with potentially wide application. Hydrothermal processes leading to the formation of large single crystals and microcrystalline powders can also be extended into the supercritical regime of water. Additional applications and potential applications are identified in the areas of extraction of binders and other additives from ceramic compacts, densification of porous ceramics, the formation of powders in supercritical micro-emulsions, and in preceramic polymer processing

  14. Psychologic effects of residency. (United States)

    Reuben, D B


    The intense situational and physiologic stresses that accompany postgraduate training may have serious psychosocial ramifications. Although only a small proportion of residents have overt psychiatric illness, virtually all display some psychologic impairment. Contributing factors include life-changes, stresses associated with providing patient care, loss of social support, long working hours, sleep deprivation, and underlying personality traits of residents. The manifestations of this impairment are variable and may be subtle. In response to these problems, residency programs have taken steps to provide psychosocial support. Unfortunately, most programs do not offer formal support groups or seminars to discuss difficulties that accompany residency. Further definition of the psychosocial effects of residency may prompt changes that make the training of physicians a more humane process.

This study tested whether a Delphi process is useful in grant selection.Materials and method: A Delphi process prioritized novel research proposals in pancreatic cancer. Five reviewers holding similar grants overseas ranked research applications by scientific merit, innovativeness, and level of risk.Result: Three rounds of voting evaluated the best 10 applications received. In the first round of the Delphi process, scores ranged from 5.0 to 8.3. After the second round, the cumulative scores of the eight remaining applications ranged from 10 to 12.6. At the end of the third round, the final cumulative scores of the remaining six applications ranged from 13.6 to 18.2. The four highest ranking applications were recommended for funding, with agreement from reviewers.Conclusion: A modified Delphi process proved to be an efficient, transparent, and equitable method of reviewing novel grant applications in a specialized field of research, where no local expertise was available. This process may also be useful for other peer review processes, particularly where there is limited access to local experts.Keywords: delphi process, research grant selection, consensus

  16. Moradia universitária: processos de socialização e consumo de drogas University residence halls: socialization processes and drug consumption

    Directory of Open Access Journals (Sweden)

    Thais Helena Mourão Laranjo


    Full Text Available OBJETIVO: Conhecer e analisar o discurso dos moradores de um conjunto residencial estudantil universitário sobre os processos de socialização e consumo de drogas. MÉTODOS: Pesquisa qualitativa, realizada com 20 alunos de graduação residentes em moradia estudantil universitária em São Paulo, SP, 2003. Tomou-se a moradia como um espaço de socialização juvenil que viabiliza a presença de estudantes de baixa renda, na universidade. As entrevistas abordaram o conhecimento dos alunos sobre a história da moradia, a experiência de viver em uma moradia estudantil e a percepção dos moradores sobre o consumo de drogas. O procedimento metodológico que serviu de base para a coleta, organização e análise das entrevistas foi o discurso do sujeito coletivo. RESULTADOS: Os resultados mostraram que: os estudantes têm pouco conhecimento sobre a história da moradia; as alternativas para os problemas que enfrentam na moradia têm sido buscadas individualmente; observou-se entre os moradores as duas principais concepções de prevenção ao consumo de drogas - guerra às drogas e redução de danos. Observou-se haver uma visão negativa sobre a moradia estudantil relacionada com a constante divulgação de fatos conturbados e com o desconhecimento sobre a importância da moradia para viabilizar a permanência de estudantes pobres na universidade. CONCLUSÕES: Na opinião de seus moradores, a moradia estudantil viabiliza o acesso a universidade, apesar de dificuldades na convivência coletiva e na administração da universidade. Em relação ao uso de drogas na moradia, parte dos moradores ressalta a necessidade de menor tolerância ao consumo de drogas e outra parte destaca a importância de trabalho educativo, principalmente com os ingressantes.OBJECTIVE: To investigate and analyze the discourse of students living in university residence halls regarding socialization processes and drug consumption.

  17. Quantifying the residence time and flushing characteristics of a shallow, back-barrier estuary: Application of hydrodynamic and particle tracking models (United States)

    Defne, Zafer; Ganju, Neil K.


    Estuarine residence time is a major driver of eutrophication and water quality. Barnegat Bay-Little Egg Harbor (BB-LEH), New Jersey, is a lagoonal back-barrier estuary that is subject to anthropogenic pressures including nutrient loading, eutrophication, and subsequent declines in water quality. A combination of hydrodynamic and particle tracking modeling was used to identify the mechanisms controlling flushing, residence time, and spatial variability of particle retention. The models demonstrated a pronounced northward subtidal flow from Little Egg Inlet in the south to Pt. Pleasant Canal in the north due to frictional effects in the inlets, leading to better flushing of the southern half of the estuary and particle retention in the northern estuary. Mean residence time for BB-LEH was 13 days but spatial variability was between ∼0 and 30 days depending on the initial particle location. Mean residence time with tidal forcing alone was 24 days (spatial variability between ∼0 and 50 days); the tides were relatively inefficient in flushing the northern end of the Bay. Scenarios with successive exclusion of physical processes from the models revealed that meteorological and remote offshore forcing were stronger drivers of exchange than riverine inflow. Investigations of water quality and eutrophication should take into account spatial variability in hydrodynamics and residence time in order to better quantify the roles of nutrient loading, production, and flushing.

  18. Applications of Digital Image Processing 11 (United States)

    Cho, Y. -C.


    A new technique, digital image velocimetry, is proposed for the measurement of instantaneous velocity fields of time dependent flows. A time sequence of single-exposure images of seed particles are captured with a high-speed camera, and a finite number of the single-exposure images are sampled within a prescribed period in time. The sampled images are then digitized on an image processor, enhanced, and superimposed to construct an image which is equivalent to a multiple exposure image used in both laser speckle velocimetry and particle image velocimetry. The superimposed image and a single-exposure Image are digitally Fourier transformed for extraction of information on the velocity field. A great enhancement of the dynamic range of the velocity measurement is accomplished through the new technique by manipulating the Fourier transform of both the single-exposure image and the superimposed image. Also the direction of the velocity vector is unequivocally determined. With the use of a high-speed video camera, the whole process from image acquisition to velocity determination can be carried out electronically; thus this technique can be developed into a real-time capability.

  19. Aggregation process, application to nuclear multifragmentation

    International Nuclear Information System (INIS)

    Garcia, Jean-Baptiste


    It is depicted an aggregation model (applied to nuclear multifragmentation) which I have elaborated and validated. This model contains an aggregation procedure, allowing one to determine the aggregation state of a given system. It takes into account spatial and kinetic nucleonic information, as well as in-medium effects. It is made of several energetic linkage criterions, all based on a single quantity: the energy of a system computed in its center of mass frame. This procedure has been applied to nuclear physics, assuming nucleus as a mix of two Fermi gas, interacting via the Yukawa potential (plus Coulomb in between protons) and obeying to a classical exclusion principle. The general trends of the model match with those of nuclear physics. Moreover, two comparisons between the model and nuclear multifragmentation experiments (ALADIN, then FOPI) exhibit nice agreements. The FOPI one, shows that fragments are bound to be formed at the beginning of the expansion phase (Au + Au at 150 MeV/nuc, for central collisions). This work ends with a study of the main ingredients included in the model. It reveals that in-medium effects, exclusion principle as well as the shape of the potential have a non negligible influence on the studied nuclear aggregation process. (author) [fr

  20. Educating doctors in the clinical workplace: Unraveling the process of teaching and learning in the medical resident as teacher

    Directory of Open Access Journals (Sweden)

    Busari J


    Full Text Available In recent years, higher medical education has witnessed major changes in the structure and content of postgraduate medical training. Seven professional competencies have been described that address the medical doctors′ ability to effectively communicate and transfer medical information, interact effectively and professionally, and demonstrate a good grasp of clinical knowledge and skills. Proficiency in didactic skills, however, is an important competency that has not received prominent attention. In the clinical setting, attending-physicians and medical residents are responsible for teaching. Consequently, several medical institutions have proposed the need for teacher training programs to improve the teaching skills of attending doctors and medical residents. The supporters of these programs believe that through teaching, medical doctors improve their individual professional and clinical problem-solving abilities. Hence, it is logical to assume that didactic skills′ training would contribute to the professional development of doctors. In this paper, we re-examine the underlying theory of the didactic proficiency, how it relates to the clinical setting, and why it may be beneficial for the professional training of medical residents.

As a kind of nonlinear signal processing method, its signal feature extraction is performed in time domain, compared with some other nonlinear and non-stationary signal processing method, which has no phase offset and amplitude attenuation etc. many advantages, so this method is applied to the signal processing in various industries. This paper mainly expounds the basic theory of mathematical morphology, and puts forward the method of mathematical morphology denoising pretreatment. Finally, the paper summarizes the application of mathematical morphology in speech signal processing and the combination of neural network.

  2. Resident Career Planning Needs in Internal Medicine: A Qualitative Assessment (United States)

    Garcia, Rina L.; Windish, Donna M.; Rosenbaum, Julie R.


    Background Few residency programs have centralized resources for career planning. As a consequence, little is known about residents' informational needs regarding career planning. Objective To examine career preparation stressors, practical needs, and information that residents wished they were privy to when applying. Methods In 2007 and 2008, we surveyed 163 recent graduates or graduating residents from 10 Yale-based and Yale-affiliated hospitals' internal medicine programs regarding their experiences with applying for positions after residency. We included questions about demographics, mentorship, stress of finding a job or fellowship, and open-ended questions to assess barriers and frustrations. Qualitative data were coded independently and a classification scheme was negotiated by consensus. Results A total of 89 residents or recent graduates responded, and 75% of them found career planning during residency training at least somewhat stressful. Themes regarding the application process included (1) knowledge about the process, (2) knowledge about career paths and opportunities, (3) time factors, (4) importance of adequate personal guidance and mentorship, and (5) self-knowledge regarding priorities and the desired outcome. Residents identified the following advice as most important: (1) start the process as early as possible and with a clear knowledge of the process timeline, (2) be clear about personal goals and priorities, and (3) be well-informed about a prospective employer and what that employer is looking for. Most residents felt career planning should be structured into the curriculum and should occur in the first year or throughout residency. Conclusions This study highlights residents' desire for structured dissemination of information and counseling with regard to career planning during residency. Our data suggest that exposure to such resources may be beneficial as early as the first year of training. PMID:22132271

  4. Plan for advanced microelectronics processing technology application

    Energy Technology Data Exchange (ETDEWEB)

    Goland, A.N.


    The ultimate objective of the tasks described in the research agreement was to identify resources primarily, but not exclusively, within New York State that are available for the development of a Center for Advanced Microelectronics Processing (CAMP). Identification of those resources would enable Brookhaven National Laboratory to prepare a program plan for the CAMP. In order to achieve the stated goal, the principal investigators undertook to meet the key personnel in relevant NYS industrial and academic organizations to discuss the potential for economic development that could accompany such a Center and to gauge the extent of participation that could be expected from each interested party. Integrated of these discussions was to be achieved through a workshop convened in the summer of 1990. The culmination of this workshop was to be a report (the final report) outlining a plan for implementing a Center in the state. As events unfolded, it became possible to identify the elements of a major center for x-ray lithography on Lone Island at Brookhaven National Laboratory. The principal investigators were than advised to substitute a working document based upon that concept in place of a report based upon the more general CAMP workshop originally envisioned. Following that suggestion from the New York State Science and Technology Foundation, the principals established a working group consisting of representatives of the Grumman Corporation, Columbia University, the State University of New York at Stony Brook, and Brookhaven National Laboratory. Regular meetings and additional communications between these collaborators have produced a preproposal that constitutes the main body of the final report required by the contract. Other components of this final report include the interim report and a brief description of the activities which followed the establishment of the X-ray Lithography Center working group.

    Jiao, Yang; Tang, Juming; Wang, Yifen; Koral, Tony L


    Radio-frequency (RF) heating, as a thermal-processing technology, has been extending its applications in the food industry. Although RF has shown some unique advantages over conventional methods in industrial drying and frozen food thawing, more research is needed to make it applicable for food safety applications because of its complex heating mechanism. This review provides comprehensive information regarding RF-heating history, mechanism, fundamentals, and applications that have already been fully developed or are still under research. The application of mathematical modeling as a useful tool in RF food processing is also reviewed in detail. At the end of the review, we summarize the active research groups in the RF food thermal-processing field, and address the current problems that still need to be overcome.

  6. Evaluation of otolaryngology residency program websites. (United States)

    Svider, Peter F; Gupta, Amar; Johnson, Andrew P; Zuliani, Giancarlo; Shkoukani, Mahdi A; Eloy, Jean Anderson; Folbe, Adam J


    Prior to applying or interviewing, most prospective applicants turn to the Internet when evaluating residency programs, making maintenance of a comprehensive website critical. While certain "intangibles" such as reputation may not be communicated effectively online, residency websites are invaluable for conveying other aspects of a program. Prior analyses have reported that certain criteria such as research experience and didactics are important considerations for applicants. To evaluate the comprehensiveness of otolaryngology residency websites. Review of otolaryngology residency program websites. Websites of 99 civilian residency programs were searched for the presence of 23 criteria. Presence of 23 criteria for application process, incentives, instruction, research, clinical training, and other. Only 5 programs contained at least three-quarters of the criteria analyzed; on average programs reported less than 50% of information sought. Among the 99 residency program websites, a description of the following criteria was noted: comprehensive faculty listing (88%), didactics (80%), contact e-mail (77%), current residents (74%), description of facilities (70%), intern schedule (70%), research requirements (69%), otolaryngology rotation schedule (64%), other courses (61%), ERAS (Electronic Residency Application Service) link (55%), year-to-year responsibility progression (47%), call schedule (40%), active/past research projects (37%), area information (34%), message from the program director (33%) or chair (23%), selection criteria (30%), salary (directly on site) (23%), surgical statistics (18%), parking (9%), and meal allowance (7%). The mean (SD) percentage present of factors encompassing "clinical training" was 55% (23%), significantly higher than the mean (SD) percentage of factors covered under the "incentives" category (19% [11%]; P = .01). The proportion of overall criteria present on websites did not differ on organizing programs by region (range, 42

  16. Bayesian networks applied to process diagnostics. Applications in energy industry

    Energy Technology Data Exchange (ETDEWEB)

    Widarsson, Bjoern (ed.); Karlsson, Christer; Dahlquist, Erik [Maelardalen Univ., Vaesteraas (Sweden); Nielsen, Thomas D.; Jensen, Finn V. [Aalborg Univ. (Denmark)


    Uncertainty in process operation occurs frequently in heat and power industry. This makes it hard to find the occurrence of an abnormal process state from a number of process signals (measurements) or find the correct cause to an abnormality. Among several other methods, Bayesian Networks (BN) is a method to build a model which can handle uncertainty in both process signals and the process itself. The purpose of this project is to investigate the possibilities to use BN for fault detection and diagnostics in combined heat and power industries through execution of two different applications. Participants from Aalborg University represent the knowledge of BN and participants from Maelardalen University have the experience from modelling heat and power applications. The co-operation also includes two energy companies; Elsam A/S (Nordjyllandsverket) and Maelarenergi AB (Vaesteraas CHP-plant), where the two applications are made with support from the plant personnel. The project ended out in two quite different applications. At Nordjyllandsverket, an application based (due to the lack of process knowledge) on pure operation data is build with capability to detect an abnormal process state in a coal mill. Detection is made through a conflict analysis when entering process signals into a model built by analysing the operation database. The application at Maelarenergi is built with a combination of process knowledge and operation data and can detect various faults caused by the fuel. The process knowledge is used to build a causal network structure and the structure is then trained by data from the operation database. Both applications are made as off-online applications, but they are ready for being run on-line. The performance of fault detection and diagnostics are good, but a lack of abnormal process states with known cause reduces the evaluation possibilities. Advantages with combining expert knowledge of the process with operation data are the possibility to represent

  17. Geothermal energy potential for district and process heating applications in the U. S. : an economic analysis

    Energy Technology Data Exchange (ETDEWEB)

    Bloomster, C.H.; Fassbender, L.L.; McDonald, C.L.


    Geothermal energy is competitive for space and process heating applications over significant distances when employed on a large scale to serve concentrated markets. Under these conditions geothermal energy from 90 to 150/sup 0/C hydrothermal resources should be economically competitive for high-density urban district heating out to distances of 50 miles from the wellhead. Supply curves (price-quantity relationships) were developed for both process heating and district heating applications for distances out to 50 miles. The 90 to 150/sup 0/C hydrothermal resources, which were identified in the assessment of geothermal resources by the U.S. Geological Survey, contain usable energy for space and process heat equivalent to 50 billion barrels of oil. The potential demand for space and process heat near these hydrothermal resources is large; over 10% of the U.S. population resides within 40 miles of the resources. The sensitivity of production costs to the important factors of production was determined. The most important factors are well costs, well flow rate, resource temperature, distance separating demand and supply, population density, size of demand, and the system load factor. Technological advances are needed to reduce costs and increase the distances over which geothermal energy can be competitive. Institutional deterrents to widespread nonelectric applications of geothermal energy will probably be significant. Among these will be the acquisition of rights-of-way, the need to organize concentrated markets, and price competition from the conventional fuels based on average cost rather than marginal cost.

  18. The surgical residency interview: a candidate-centered, working approach. (United States)

    Seabott, Heather; Smith, Ryan K; Alseidi, Adnan; Thirlby, Richard C


    The interview process is a pivotal, differentiating component of the residency match. Our bias is toward a working interview, producing better fulfillment of the needs of both parties, and a more informed match selection for the candidates and program. We describe a "candidate-centered" approach for integrating applicant interviews into our daily work schedule. Applicants are informed upon accepting the interview of the working interview model. Our program offers 33 interview days over a 12-week period. A maximum of 5 applicants are hosted per day. Applicants are assigned to 1 of our general, thoracic, vascular, or plastic surgery teams. The interview day begins with the applicant changing into scrubs, attending a morning conference, and taking part in a program overview by a Chief Resident. Applicants join their host team where 4-8 hours are spent observing the operative team, on rounds and sharing lunch. The faculty and senior residents are responsible for interviewing and evaluating applicants though the Electronic Residency Application Service. A total of 13 surgeons are involved in the interview process resulting in broad-based evaluations. Each surgeon interviewed between 3 and 12 applicants. Faculty rate this interview approach highly because it allows them to maintain a rigorous operative schedule while interacting with applicants. Current residents are engaged in welcoming applicants to view the program. Faculty and residents believe cooperating in a real world manner aids their assessment of the applicant. Applicants routinely provide positive feedback, relaying this approach is informative, transparent, and should be the "standard." Applicants believe they are presented a realistic view of the program. Ultimately, this candidate-centered process may be attributable to our resident cohort who exhibit high satisfaction, excellent resident morale, and very low dropout rate. We present a candidate-centered, working interview approach used in the selection of

  19. Application Of White-Light Processing To Interferometric Studies (United States)

    Yu, F. T. S.; Jutamulia, S.


    One of the interesting applications of white-light optical signal processing must be psuedocolor encoding. In this paper, we will demonstrate some of those applications to holographic interferometric and metrological studies. Techniques of producing pseudocolor encoded holographic fringe patterns and misfocused speckle interferograms are provided. These techniques allow the viewing of a multiset of encoded interferograms simultaneously. Talbot interferometric technique for pseudocolor encoding phase object and depth utilizing a white-light processor is also presented. The white-light optical processing technique offers the simplicity, versatility, and cost effectiveness in the application to interferometric and metrological studies.

  20. Still under the microscope: can a surgical aptitude test predict otolaryngology resident performance? (United States)

    Moore, Eric J; Price, Daniel L; Van Abel, Kathryn M; Carlson, Matthew L


    Application to otolaryngology-head and neck surgery residency is highly competitive, and the interview process strives to select qualified applicants with a high aptitude for the specialty. Commonly employed criteria for applicant selection have failed to show correlation with proficiency during residency training. We evaluate the correlation between the results of a surgical aptitude test administered to otolaryngology resident applicants and their performance during residency. Retrospective study at an academic otolaryngology-head and neck surgery residency program. Between 2007 and 2013, 224 resident applicants participated in a previously described surgical aptitude test administered at a microvascular surgical station. The composite score and attitudinal scores for 24 consecutive residents who matched at our institution were recorded, and their residency performance was analyzed by faculty survey on a five-point scale. The composite and attitudinal scores were analyzed for correlation with residency performance score by regression analysis. Twenty-four residents were evaluated for overall quality as a clinician by eight faculty members who were blinded to the results of surgical aptitude testing. The results of these surveys showed good inter-rater reliability. Both the overall aptitude test scores and the subset attitudinal score showed reliability in predicting performance during residency training. The goal of the residency selection process is to evaluate the candidate's potential for success in residency and beyond. The results of this study suggest that a simple-to-administer clinical skills test may have predictive value for success in residency and clinician quality. 4. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    International Nuclear Information System (INIS)

    Sotiropoulou, C.-L.; Citraro, S.; Dell'Orso, M.; Luciano, P.; Gkaitatzis, S.; Giannetti, P.


    We present an embedded system for extremely efficient real-time pattern recognition execution, enabling technological advancements with both scientific and social impact. It is a compact, fast, low consumption processing unit (PU) based on a combination of Field Programmable Gate Arrays (FPGAs) and the full custom associative memory chip. The PU has been developed for real time tracking in particle physics experiments, but delivers flexible features for potential application in a wide range of fields. It has been proposed to be used in accelerated pattern matching execution for Magnetic Resonance Fingerprinting (biomedical applications), in real time detection of space debris trails in astronomical images (space applications) and in brain emulation for image processing (cognitive image processing). We illustrate the potentiality of the PU for the new applications.

  4. Permanent resident

    Directory of Open Access Journals (Sweden)

    John F. Fisher


    Full Text Available The training of physicians in the past century was based primarily on responsibility and the chain-of-command. Those with the bulk of that responsibility in the fields of pediatrics and internal medicine were residents. Residents trained the medical students and supervised them carefully in caring for patients. Most attending physicians supervised their teams at arm's length, primarily serving as teachers of the finer points of diagnosis and treatment during set periods of the day or week with a perfunctory signature on write-ups or progress notes. Residents endeavored to protect the attending physician from being heavily involved unless they were unsure about a clinical problem. Before contacting the attending physician, a more senior resident would be called. Responsibility was the ultimate teacher. The introduction of diagnosis-related groups by the federal government dramatically changed the health care delivery system, placing greater emphasis on attending physician visibility in the medical record, ultimately resulting in more attending physician involvement in day-to-day care of patients in academic institutions. Without specified content in attending notes, hospital revenues would decline. Although always in charge technically, attending physicians increasingly have assumed the role once dominated by the resident. Using biographical experiences of more than 40 years, the author acknowledges and praises the educational role of responsibility in his own training and laments its declining role in today's students and house staff.

Bifrost uses a flexible ring buffer implementation that allows different signal processing blocks to be connected to form a pipeline. Each block may be assigned to a CPU core, and the ring buffers are used to transport data to and from blocks. Processing blocks may be run on either the CPU or GPU, and the ring buffer will take care of memory copies between the CPU and GPU spaces.

  11. Prospects of HTGR process heat application and role of HTTR

    International Nuclear Information System (INIS)

    Shiozawa, S.; Miyamoto, Y.


    At Japan Atomic Energy Research Institute, an effort on development of process heat application with high temperature gas cooled reactor (HTGR) has been continued for providing a future clean alternative to the burning of fossil energy for the production of industrial process heat. The project is named 'HTTR Heat Utilization Project', which includes a demonstration of hydrogen production using the first Japanese HTGR of High Temperature Engineering Test Reactor (HTTR). In the meantime, some countries, such as China, Indonesia, Russia and South Africa are trying to explore the HTGR process heat application for industrial use. One of the key issues for this application is economy. It has been recognized for a long time and still now that the HTGR heat application system is not economically competitive to the current fossil ones, because of the high cost of the HTGR itself. However, the recent movement on the HTGR development, as represented by South Africa Pebble Beds Modular Reactor (SA-PBMR) Project, has revealed that the HTGRs are well economically competitive in electricity production to fossil fuel energy supply under a certain condition. This suggests that the HTGR process heat application will also possibly get economical in the near future. In the present paper, following a brief introduction describing the necessity of the HTGRs for the future process heat application, Japanese activities and prospect of the development on the process heat application with the HTGRs are described in relation with the HTTR Project. In conclusion, the process heat application system with HTGRs is thought technically and economically to be one of the most promising applications to solve the global environmental issues and energy shortage which may happen in the future. However, the commercialization for the hydrogen production system from water, which is the final goal of the HTGR process heat application, must await the technology development to be completed in 2030's at the

    International Nuclear Information System (INIS)

    Popovska-Vasilevska, Sanja


    In the worldwide practice, the geothermal energy application, as an alternative energy resource, can be of great importance. This is especially case in the countries where exceptional natural geothermal potential exists. Despite using geothermal energy for both greenhouses heating and balneology, the one can be successfully implemented in the heat requiring industrial processes. This kind of use always provides greater annual heat loading factor, since the industrial processes are not seasonal (or not the greater part of them). The quality of the geothermal resources that are available in Europe, dictates the use within the low-temperature range technological processes. However, these processes are significantly engaged in different groups of processing industries. But, beside this fact the industrial application of geothermal energy is at the beginning in the Europe. (Original)

  13. Applications of nuclear magnetic resonance imaging in process engineering (United States)

    Gladden, Lynn F.; Alexander, Paul


    During the past decade, the application of nuclear magnetic resonance (NMR) imaging techniques to problems of relevance to the process industries has been identified. The particular strengths of NMR techniques are their ability to distinguish between different chemical species and to yield information simultaneously on the structure, concentration distribution and flow processes occurring within a given process unit. In this paper, examples of specific applications in the areas of materials and food processing, transport in reactors and two-phase flow are discussed. One specific study, that of the internal structure of a packed column, is considered in detail. This example is reported to illustrate the extent of new, quantitative information of generic importance to many processing operations that can be obtained using NMR imaging in combination with image analysis.

    Katarina Monkova


    Full Text Available The purchase of a complex system for computer aided process planning (CAPP can be expensive for little and some middle sized plants, sometimes an inaccessible investment, with a long recoupment period. According to this fact and the author's experience with Eastern European plants, they decided to design a new database application which is suitable for production, stock, and economic data holding as well as processing and exploitation within the manufacturing process. The application can also be used to process a plan according to the selected criteria, for technological documentation and NC program creation. It was based on the theory of a multivariant approach to computer aided plan generation. Its fundamental features, the internal mathematical structure and new code system of processed objects, were prepared by the authors. The verification of the designed information system in real practice has shown that it enables about 30% cost and production time reduction and decreases input material assortment variability.

  15. Fluctuations of Lévy processes with applications introductory lectures

    CERN Document Server

    Kyprianou, Andreas E


    Lévy processes are the natural continuous-time analogue of random walks and form a rich class of stochastic processes around which a robust mathematical theory exists. Their application appears in the theory of many areas of classical and modern stochastic processes including storage models, renewal processes, insurance risk models, optimal stopping problems, mathematical finance, continuous-state branching processes and positive self-similar Markov processes. This textbook is based on a series of graduate courses concerning the theory and application of Lévy processes from the perspective of their path fluctuations. Central to the presentation is the decomposition of paths in terms of excursions from the running maximum as well as an understanding of short- and long-term behaviour. The book aims to be mathematically rigorous while still providing an intuitive feel for underlying principles. The results and applications often focus on the case of Lévy processes with jumps in only one direction, for which r...

  16. Review of computational fluid dynamics applications in biotechnology processes. (United States)

    Sharma, C; Malhotra, D; Rathore, A S


    Computational fluid dynamics (CFD) is well established as a tool of choice for solving problems that involve one or more of the following phenomena: flow of fluids, heat transfer,mass transfer, and chemical reaction. Unit operations that are commonly utilized in biotechnology processes are often complex and as such would greatly benefit from application of CFD. The thirst for deeper process and product understanding that has arisen out of initiatives such as quality by design provides further impetus toward usefulness of CFD for problems that may otherwise require extensive experimentation. Not surprisingly, there has been increasing interest in applying CFD toward a variety of applications in biotechnology processing in the last decade. In this article, we will review applications in the major unit operations involved with processing of biotechnology products. These include fermentation,centrifugation, chromatography, ultrafiltration, microfiltration, and freeze drying. We feel that the future applications of CFD in biotechnology processing will focus on establishing CFD as a tool of choice for providing process understanding that can be then used to guide more efficient and effective experimentation. This article puts special emphasis on the work done in the last 10 years. © 2011 American Institute of Chemical Engineers

  17. Agricultural and Food Processing Applications of Pulsed Power Technology (United States)

    Takaki, Koichi; Ihara, Satoshi

    Recent progress of agricultural and food processing applications of pulsed power is described in this paper. Repetitively operated compact pulsed power generators with a moderate peak power have been developed for the agricultural and the food processing applications. These applications are mainly based on biological effects and can be categorized as decontamination of air and liquid, germination promotion, inhabitation of saprophytes growth, extraction of juice from fruits and vegetables, and fertilization of liquid medium, etc. Types of pulsed power that have biological effects are caused with gas discharges, water discharges, and electromagnetic fields. The discharges yield free radicals, UV radiation, intense electric field, and shock waves. Biologically based applications of pulsed power are performed by selecting the type that gives the target objects the adequate result from among these agents or byproducts. For instance, intense electric fields form pores on the cell membrane, which is called electroporation, or influence the nuclei.

    Daramola, Michael O.; Aransiola, Elizabeth F.; Ojumu, Tunde V.


    Future production of chemicals (e.g., fine and specialty chemicals) in industry is faced with the challenge of limited material and energy resources. However, process intensification might play a significant role in alleviating this problem. A vision of process intensification through multifunctional reactors has stimulated research on membrane-based reactive separation processes, in which membrane separation and catalytic reaction occur simultaneously in one unit. These processes are rather attractive applications because they are potentially compact, less capital intensive, and have lower processing costs than traditional processes. Therefore this review discusses the progress and potential applications that have occurred in the field of zeolite membrane reactors during the last few years. The aim of this article is to update researchers in the field of process intensification and also provoke their thoughts on further research efforts to explore and exploit the potential applications of zeolite membrane reactors in industry. Further evaluation of this technology for industrial acceptability is essential in this regard. Therefore, studies such as techno-economical feasibility, optimization and scale-up are of the utmost importance.

    Salerno, Sergio; Tudisca, Chiara; Murmura, Elena; Matranga, Domenica; La Tona, Giuseppe; Lo Re, Giuseppe; Lo Casto, Antonio


    Umbilical Venous Catheter (UVC) are commonly used in neonatal period; they can be not correctly positioned and could be associated with complications. The purpose of this article is to suggest a flow-chart to evaluate the placement of UVC, testing it in young radiologists-in-training. We developed a simple flow-chart to asses, steps by step, UVC placement considering its course and tip location (ideally placed in the atriocaval junction). We tested the flow-chart impact asking to 20 residents to evaluate the placement of 10 UVC before and after they familiarized with the flow-chart and the anatomical findings of a newborn. The agreement among the 20 students was evaluated too. The number of correct characterizations was different due to the administration of the flow-chart. One hundred and six correct UVC assessments at the beginning switched to 196 after the administration of the flow-chart (p = 0.0001). The observed agreement among the twenty radiology residents was statistically significant, both before (kappa = 0.41, p < 0.001) and after (kappa = 0.37, p < 0.001) the flow-chart administration. The developed flow-chart demonstrated to be useful in increasing residents performance in UVC placement assessment.

  19. Is orthopedics more competitive today than when my attending matched? An analysis of National Resident Matching Program data for orthopedic PGY1 applicants from 1984 to 2011. (United States)

    Karnes, Jonathan M; Mayerson, Joel L; Scharschmidt, Thomas J


    This study evaluated supply and demand trends for orthopedic postgraduate year 1 (PGY1) positions from 1984 to 2011 for the purpose of estimating national intercandidate competition over time. National Resident Matching Program (NRMP) data for orthopedic surgery from 1984 to 2011 were collected. Proxy variables including (total number of orthopedic applicants/number of orthopedic PGY1 positions), (number of US senior applicants to orthopedics/number of orthopedic PGY1 positions), (number of US seniors matching into orthopedics/number of US senior orthopedic applicants), (total number of matched orthopedic applicants/total number of orthopedic applicants), and (total number of US applicants who fail to match into orthopedics/total number of US senior applicants into orthopedics) as well as average United States Medical Licensing Examination Step 1 scores were used to gauge the level of competition between candidates and were compared over time. Academic medical center in the Midwestern United States. Medical professors and medical students. The NRMP data suggested that the number of positions per applicant decreased or remained stable since 1984 and that the percentage of applicants who did not match was no higher now than in the past. This finding was primarily because of the relative decrease in the ratio of applicants to available PGY1 positions, which stems from the number of positions increasing more rapidly than the number of applicants. The NRMP data from 1984 to 2011 supported our hypothesis that intercandidate competition intensity for orthopedic PGY1 positions has not increased over time. The misconception that orthopedics is becoming more competitive likely arises from the increased number of applications submitted per candidate and the resulting relative importance placed on objective criteria such as United States Medical Licensing Examination Step 1 scores when programs select interview cohorts.

  20. Coagulation effect on the activity size distributions of long lived radon progeny aerosols and its application to atmospheric residence time estimation techniques. (United States)

    Anand, S; Mayya, Y S


    The long lived naturally occurring radon progeny species in the atmosphere, namely (210)Pb, (210)Bi and (210)Po, have been used as important tracers for understanding the atmospheric mixing processes and estimating aerosol residence times. Several observations in the past have shown that the activity size distribution of these species peaks at larger particle sizes as compared to the short lived radon progeny species - an effect that has been attributed to the process of coagulation of the background aerosols to which they are attached. To address this issue, a mathematical equation is derived for the activity-size distribution of tracer species by formulating a generalized distribution function for the number of tracer atoms present in coagulating background particles in the presence of radioactive decay and removal. A set of these equations is numerically solved for the progeny chain using Fuchs coagulation kernel combined with a realistic steady-state aerosol size spectrum that includes nucleation, accumulation and coarse mode components. The important findings are: (i) larger shifts in the modal sizes of (210)Pb and (210)Po at higher aerosol concentrations such as that found in certain Asian urban regions (ii) enrichment of tracer specific activity on particles as compared to that predicted by pure attachment laws (iii) sharp decline of daughter-to-parent activity ratios for decreasing particle sizes. The implication of the results to size-fractionated residence time estimation techniques is highlighted. A coagulation corrected graphical approach is presented for estimating the residence times from the size-segregated activity ratios of (210)Bi and (210)Po with respect to (210)Pb. The discrepancy between the residence times predicted by conventional formula and the coagulation corrected approach for specified activity ratios increases at higher atmospheric aerosol number concentrations (>10(10) #/m(3)) for smaller sizes (<1 μm). The results are further

  12. Applicability and trends of anaerobic granular sludge treatment processes

    International Nuclear Information System (INIS)

    Lim, Seung Joo; Kim, Tak-Hyun


    Anaerobic granular sludge treatment processes have been continuously developed, although the anaerobic sludge granulation process was not clearly understood. In this review, an upflow anaerobic sludge blanket (UASB), an expanded granule sludge blanket (EGSB), and a static granular bed reactor (SGBR) were introduced as components of a representative anaerobic granular sludge treatment processes. The characteristics and application trends of each reactor were presented. The UASB reactor was developed in the late 1970s and its use has been rapidly widespread due to the excellent performance. With the active granules, this reactor is able to treat various high-strength wastewaters as well as municipal wastewater. Most soluble industrial wastewaters can be efficiently applied using a UASB. The EGSB reactor was developed owing to give more chance to contact between wastewater and the granules. Dispersed sludge is separated from mature granules using the rapid upward velocity in this reactor. The EGSB reactor shows the excellent performance in treating low-strength and/or high-strength wastewater, especially under low temperatures. The SGBR, developed at Iowa State University, is one of anaerobic granular sludge treatment processes. Although the configuration of the SGBR is very simple, the performance of this system is similar to that of the UASB or EGSB reactor. The anaerobic sludge granulation processes showed excellent performance for various wastewaters at a broad range of organic loading rate in lab-, pilot-scale tests. This leads to erect thousands of full-scale granular processes, which has been widely operated around the world. -- Highlights: • Anaerobic sludge granulation is a key parameter for maintaining granular processes. • Anaerobic granular digestion processes are applicable for various wastewaters. • The UASB is an economic high-rate anaerobic granular process. • The EGSB can treat high-strength wastewater using expanding granules. • The SGBR is

    Ito, Masashi; Ueda, Katsuhiko; Takagi, Soya


    Recently in Japan, laser processing is increasingly being employed for production, so that laser cutting, laser welding and other laser material processing have begun to be used in various industries. As a result, the number of lasers sold has been increasing year by year in Japan. In the Japanese automotive industry, a number applications have been introduced in laboratories and production lines. In this paper, several current instances of such laser applications will be introduced. In the case of welding, studies have been conducted on applying laser welding to automatic transmission components, in place of electron beam welding. Another example of application, the combination of lasers and robots to form highly flexible manufacturing systems, has been adopted for trimming steel panel and plastic components.

  14. New applications and novel processing of refractory metal alloys

    International Nuclear Information System (INIS)

    Briant, C.L.


    Refractory metals have often been limited in their application because of their propensity to oxidize and to undergo a loos of yield strength at elevated temperatures. However, recent developments in both processing and alloy composition have opened the possibility that these materials might be used in structural applications that were not considered possible in the past. At the same time, the use of refractory metals in the electronics industry is growing, particularly with the use of tantalum as a diffusion barrier for copper metallization. Finally, the application of grain boundary engineering to the problem of intergranular fracture in these materials may allow processes to be developed that will produce alloys with a greater resistance to fracture.

  1. Application of multistage process control methodology for software quality management

    Directory of Open Access Journals (Sweden)

    Boby John


    Full Text Available As the need for software increased, the number of software firms and the competition among them also increased. The software companies in developing countries like India can no longer survive based on cost advantage alone. The firms need to deliver competitively priced quality software products on time. This can be achieved through quantitatively managing the different phases or sub processes in software development process. But quantitative management of a process consisting of a set of interlinked sub processes or stages with the output of one sub pro-cess influencing that of subsequent stages and final output is not easy. The process performance models developed for quantitative management of software development process often model the final outcome in terms of factors from various stages together or focuses only on quantitatively managing a particular sub process independently. In manufacturing and other engineering indus-tries, the processes with multiple sub process are monitored and controlled using multistage pro-cess control methodology. This paper is an application of multistage statistical process control for managing the software development process. The suggested methodology is a combination of process performance models and control charts. The proposed methodology can be easily im-plemented for controlling various types of software projects like development projects, incre-mental development projects, testing projects etc. The methodology also provides the project manager the opportunity to tighten or relax the control at various sub processes based on the pro-ject team’s strengths and still achieve the goal on the final outcome.

  2. [Sustainable process improvement with application of 'lean philosophy']. (United States)

    Rouppe van der Voort, Marc B V; van Merode, G G Frits; Veraart, Henricus G N


    Process improvement is increasingly being implemented, particularly with the aid of 'lean philosophy'. This management philosophy aims to improve quality by reducing 'wastage'. Local improvements can produce negative effects elsewhere due to interdependence of processes. An 'integrated system approach' is required to prevent this. Some hospitals claim that this has been successful. Research into process improvement with the application of lean philosophy has reported many positive effects, defined as improved safety, quality and efficiency. Due to methodological shortcomings and lack of rigorous evaluations it is, however, not yet possible to determine the impact of this approach. It is, however, obvious that the investigated applications are fragmentary, with a dominant focus on the instrumental aspect of the philosophy and a lack of integration in a total system, and with insufficient attention to human aspects. Process improvement is required to achieve better and more goal-oriented healthcare. To achieve this, hospitals must develop integrated system approaches that combine methods for process design with continuous improvement of processes and with personnel management. It is crucial that doctors take the initiative to guide and improve processes in an integral manner.

  5. A systematic process for persuasive mobile healthcare applications (United States)

    Qasim, Mustafa Moosa; Ahmad, Mazida; Omar, Mazni; Zulkifli, Abdul Nasir; Bakar, Juliana Aida Abu


    In recent years there has been an increased focus on persuasive design of mobile in the healthcare domain. However, most of the studies did not follow systematic processes while analysis and designing the persuasive technology applications, and they also failed to provide some of the relevant information needed to design the persuasive applications. Adding to this is a need for more guidance in order to set how the persuasive guidelines can be implemented, which also means that there is a need for a way to transform the persuasive components into software requirements and functionalities. Therefore, this paper proposes a general systematic process to be used independently of the problem domain in order to analyze the customers' significant requirements. Such domain is the obesity problem among Malaysian children, and the most significant treatment of this case is parents' involvement. To this end, this paper will apply a systematic process in monitoring the children's obesity status among parents.

  7. Strontium isotopes as tracers of water-rocks interactions, mixing processes and residence time indicator of groundwater within the granite-carbonate coastal aquifer of Bonifacio (Corsica, France). (United States)

    Santoni, S; Huneau, F; Garel, E; Aquilina, L; Vergnaud-Ayraud, V; Labasque, T; Celle-Jeanton, H


    This study aims at identifying the water-rock interactions and mixing rates within a complex granite-carbonate coastal aquifer under high touristic pressure. Investigations have been carried out within the coastal aquifer of Bonifacio (southern Corsica, France) mainly composed of continental granitic weathering products and marine calcarenite sediments filling a granitic depression. A multi-tracer approach combining physico-chemical parameters, major ions, selected trace elements, stable isotopes of the water molecule and 87 Sr/ 86 Sr ratios measurements is undertaken for 20 groundwater samples during the low water period in November 2014. 5 rock samples of the sedimentary deposits and surrounding granites are also analysed. First, the water-rock interactions processes governing the groundwater mineralization are described in order to fix the hydrogeochemical background. Secondly, the flow conditions are refined through the quantification of inter aquifer levels mixing, and thirdly, the kinetics of water-rock interaction based on groundwater residence time from a previous study using CFCs and SF 6 are quantified for the two main flow lines. A regional contrast in the groundwater recharge altitude allowed the oxygene-18 to be useful combined with the 87 Sr/ 86 Sr ratios to differentiate the groundwater origins and to compute the mixing rates, revealing the real extension of the watershed and the availability of the resource. The results also highlight a very good correlation between the groundwater residence time and the spatial evolution of 87 Sr/ 86 Sr ratios, allowing water-rock interaction kinetics to be defined empirically for the two main flow lines through the calcarenites. These results demonstrate the efficiency of strontium isotopes as tracers of water-rock interaction kinetics and by extension their relevance as a proxy of groundwater residence time, fundamental parameter documenting the long term sustainability of the hydrosystem.

  8. Application of Ozone MBBR Process in Refinery Wastewater Treatment (United States)

    Lin, Wang


    Moving Bed Biofilm Reactor (MBBR) is a kind of sewage treatment technology based on fluidized bed. At the same time, it can also be regarded as an efficient new reactor between active sludge method and the biological membrane method. The application of ozone MBBR process in refinery wastewater treatment is mainly studied. The key point is to design the ozone +MBBR combined process based on MBBR process. The ozone +MBBR process is used to analyze the treatment of concentrated water COD discharged from the refinery wastewater treatment plant. The experimental results show that the average removal rate of COD is 46.0%~67.3% in the treatment of reverse osmosis concentrated water by ozone MBBR process, and the effluent can meet the relevant standard requirements. Compared with the traditional process, the ozone MBBR process is more flexible. The investment of this process is mainly ozone generator, blower and so on. The prices of these items are relatively inexpensive, and these costs can be offset by the excess investment in traditional activated sludge processes. At the same time, ozone MBBR process has obvious advantages in water quality, stability and other aspects.

  13. Estimation of Transport Trajectory and Residence Time in Large River–Lake Systems: Application to Poyang Lake (China Using a Combined Model Approach

    Directory of Open Access Journals (Sweden)

    Yunliang Li


    Full Text Available The biochemical processes and associated water quality in many lakes mainly depend on their transport behaviors. Most existing methodologies for investigating transport behaviors are based on physically based numerical models. The pollutant transport trajectory and residence time of Poyang Lake are thought to have important implications for the steadily deteriorating water quality and the associated rapid environmental changes during the flood period. This study used a hydrodynamic model (MIKE 21 in conjunction with transport and particle-tracking sub-models to provide comprehensive investigation of transport behaviors in Poyang Lake. Model simulations reveal that the lake’s prevailing water flow patterns cause a unique transport trajectory that primarily develops from the catchment river mouths to the downstream area along the lake’s main flow channels, similar to a river-transport behavior. Particle tracking results show that the mean residence time of the lake is 89 days during July–September. The effect of the Yangtze River (the effluent of the lake on the residence time is stronger than that of the catchment river inflows. The current study represents a first attempt to use a combined model approach to provide insights into the transport behaviors for a large river–lake system, given proposals to manage the pollutant inputs both directly to the lake and catchment rivers.

  14. Safety applications of computer based systems for the process industry

    International Nuclear Information System (INIS)

    Bologna, Sandro; Picciolo, Giovanni; Taylor, Robert


    Computer based systems, generally referred to as Programmable Electronic Systems (PESs) are being increasingly used in the process industry, also to perform safety functions. The process industry as they intend in this document includes, but is not limited to, chemicals, oil and gas production, oil refining and power generation. Starting in the early 1970's the wide application possibilities and the related development problems of such systems were recognized. Since then, many guidelines and standards have been developed to direct and regulate the application of computers to perform safety functions (EWICS-TC7, IEC, ISA). Lessons learnt in the last twenty years can be summarised as follows: safety is a cultural issue; safety is a management issue; safety is an engineering issue. In particular, safety systems can only be properly addressed in the overall system context. No single method can be considered sufficient to achieve the safety features required in many safety applications. Good safety engineering approach has to address not only hardware and software problems in isolation but also their interfaces and man-machine interface problems. Finally, the economic and industrial aspects of the safety applications and development of PESs in process plants are evidenced throughout all the Report. Scope of the Report is to contribute to the development of an adequate awareness of these problems and to illustrate technical solutions applied or being developed

  15. Application of lithium in molten-salt reduction processes

    International Nuclear Information System (INIS)

    Gourishankar, K. V.


    Metallothermic reductions have been extensively studied in the field of extractive metallurgy. At Argonne National Laboratory (ANL), we have developed a molten-salt based reduction process using lithium. This process was originally developed to reduce actinide oxides present in spent nuclear fuel. Preliminary thermodynamic considerations indicate that this process has the potential to be adapted for the extraction of other metals. The reduction is carried out at 650 C in a molten-salt (LiCl) medium. Lithium oxide (Li 2 O), produced during the reduction of the actinide oxides, dissolves in the molten salt. At the end of the reduction step, the lithium is regenerated from the salt by an electrowinning process. The lithium and the salt from the electrowinning are then reused for reduction of the next batch of oxide fuel. The process cycle has been successfully demonstrated on an engineering scale in a specially designed pyroprocessing facility. This paper discusses the applicability of lithium in molten-salt reduction processes with specific reference to our process. Results are presented from our work on actinide oxides to highlight the role of lithium and its effect on process variables in these molten-salt based reduction processes

  16. An application of object-oriented programming to process simulation

    International Nuclear Information System (INIS)

    Robinson, J.T.; Otaduy, P.J.


    This paper discusses the application of object-oriented programming to dynamic simulation of continuous processes. Processes may be modeled using this technique as a collection of objects which communicate with each other via message passing. Arriving messages invoke methods that describe the state and/or dynamic behavior of the receiving object. The objects fall into four broad categories actual plant components such as pumps, pipes, and tanks, abstract objects such as heat sources and conductors, plant systems such as flow loops, and simulation control and interface objects. This technique differs from traditional approaches to process simulation, in which the process is represented by either a system of differential equations or a block diagram of mathematical operators. The use of objects minimizes the representational gap between the model and actual process. From the users point of view, construction of a simulation model becomes equivalent to drawing a plant schematic. As an example application, a package developed for the simulation of nuclear power plants is described. The package allows users to build simulation models by selecting iconic representations of plant components from a menu and connecting them with a mouse. Objects for generating a mathematical model of the system and for controlling the simulation are automatically generated, freeing the user to concentrate on describing his process. This example illustrates the use of object-oriented programming to create a highly interactive and automated simulation environment. 2 figs

  19. Nanotechnology in meat processing and packaging: potential applications - a review. (United States)

    Ramachandraiah, Karna; Han, Sung Gu; Chin, Koo Bok


    Growing demand for sustainable production, increasing competition and consideration of health concerns have led the meat industries on a path to innovation. Meat industries across the world are focusing on the development of novel meat products and processes to meet consumer demand. Hence, a process innovation, like nanotechnology, can have a significant impact on the meat processing industry through the development of not only novel functional meat products, but also novel packaging for the products. The potential benefits of utilizing nanomaterials in food are improved bioavailability, antimicrobial effects, enhanced sensory acceptance and targeted delivery of bioactive compounds. However, challenges exist in the application of nanomaterials due to knowledge gaps in the production of ingredients such as nanopowders, stability of delivery systems in meat products and health risks caused by the same properties which also offer the benefits. For the success of nanotechnology in meat products, challenges in public acceptance, economics and the regulation of food processed with nanomaterials which may have the potential to persist, accumulate and lead to toxicity need to be addressed. So far, the most promising area for nanotechnology application seems to be in meat packaging, but the long term effects on human health and environment due to migration of the nanomaterials from the packaging needs to be studied further. The future of nanotechnology in meat products depends on the roles played by governments, regulatory agencies and manufacturers in addressing the challenges related to the application of nanomaterials in food.

As in other HTGR designs, the HTGR-PH has its entire primary coolant system contained in a prestressed concrete reactor vessel (PCRV) which provides the necessary biological shielding and pressure containment. The high-temperature nuclear thermal energy is transported to the externally located process plant by a secondary helium transport loop. With a capability to produce hot helium in the secondary loop at 800 0 C (1472 0 F) with current designs and 900 0 C (1652 0 F) with advanced designs, a large number of process heat applications are potentially available. Studies have been performed for coal liquefaction and gasification using nuclear heat

    Separation of hydrogen iodide from HIx solution (HI-I 2 -H 2 O mixture) is one of the technical issues in the development of thermochemical IS process. Application of pervaporation (PV) to the concentration of HIx solution in the IS process pilot test plant was discussed from the viewpoints of process heat mass balance, conceptual design of the apparatus, and the corrosion resistance of the membrane module. Compared with the electro-electrodialysis system, the PV system enables the downsizing of apparatus by using hollow fiber membranes, although it does not improve the thermal efficiency of IS process. Immersion tests of commercially available Nafion hollow fiber membrane module in the HIx solution at 100degC indicated the necessity of improving the corrosion resistance of bundle materials.

    Full Text Available Chemical processes are systems that include complicated network of material, energy and process flow. As time passes, the performance of chemical process gradually degrades due to the deterioration of process equipments and components. The early detection and diagnosis of faults in chemical processes is very important both from the viewpoint of plant safety as well as reduced manufacturing costs. The conventional way used in fault detection and diagnosis is through the use of models of the process, which is not easy to be achieved in many cases. In recent years, an artificial intelligence technique such as neural network has been successfully used for pattern recognition and as such it can be suitable for use in fault diagnosis of processes [1]. The application of neural network methods in process fault detection and diagnosis is demonstrated in this work in two case studies using simulated chemical plant systems. Both systems were successfully diagnosed of the faults introduced in them. The neural networks were able to generalise to successfully diagnosed fault combinations it was not explicitly trained upon. Thus, neural network can be fully applied in industries as it has shown several advantages over the conventional way in fault diagnosis.

  7. Bacteriophages-potential for application in wastewater treatment processes

    International Nuclear Information System (INIS)

    Withey, S.; Cartmell, E.; Avery, L.M.; Stephenson, T.


    Bacteriophages are viruses that infect and lyse bacteria. Interest in the ability of phages to control bacterial populations has extended from medical applications into the fields of agriculture, aquaculture and the food industry. Here, the potential application of phage techniques in wastewater treatment systems to improve effluent and sludge emissions into the environment is discussed. Phage-mediated bacterial mortality has the potential to influence treatment performance by controlling the abundance of key functional groups. Phage treatments have the potential to control environmental wastewater process problems such as: foaming in activated sludge plants; sludge dewaterability and digestibility; pathogenic bacteria; and to reduce competition between nuisance bacteria and functionally important microbial populations. Successful application of phage therapy to wastewater treatment does though require a fuller understanding of wastewater microbial community dynamics and interactions. Strategies to counter host specificity and host cell resistance must also be developed, as should safety considerations regarding pathogen emergence through transduction

  10. Near net shape processing: A necessity for advanced materials applications (United States)

    Kuhn, Howard A.


    High quality discrete parts are the backbones for successful operation of equipment used in transportation, communication, construction, manufacturing, and appliances. Traditional shapemaking for discrete parts is carried out predominantly by machining, or removing unwanted material to produce the desired shape. As the cost and complexity of modern materials escalates, coupled with the expense and environmental hazards associated with handling of scrap, it is increasingly important to develop near net shape processes for these materials. Such processes involve casting of liquid materials, consolidation of powder materials, or deformation processing of simple solid shapes into the desired shape. Frequently, several of these operations may be used in sequence to produce a finished part. The processes for near net shape forming may be applied to any type of material, including metals, polymers, ceramics, and their composites. The ability to produce shapes is the key to implementation of laboratory developments in materials science into real world applications. This seminar presents an overview of near net shapemaking processes, some application examples, current developments, and future research opportunities.

  11. Assessment of very high temperature reactors in process applications

    International Nuclear Information System (INIS)

    Jones, J.E. Jr.; Spiewak, I.; Gambill, W.R.


    In April 1974, the United States Energy Research and Development Administration (ERDA) authorized General Atomic Company, General Electric Company, and Westinghouse Astronuclear Laboratory to assess the available technology for producing process heat utilizing a very high temperature nuclear reactor (VHTR). The VHTR is defined as a gas-cooled graphite-moderated reactor. Oak Ridge National Laboratory has been given a lead role in evaluating the VHTR reactor studies and potential applications of the VHTR. Process temperatures up to the 760 to 871 0 C range appear to be achievable with near-term technology. The major development considerations are high temperature materials, the safety questions (especially regarding the need for an intermediate heat exchanger) and the process heat exchanger. The potential advantages of the VHTR over competing fossil energy sources are conservation of fossil fuels and reduced atmospheric impacts. Costs are developed for nuclear process heat supplied from a 3000-MW(th) VHTR. The range of cost in process applications is competitive with current fossil fuel alternatives

  12. Metastable memristive lines for signal transmission and information processing applications (United States)

    Slipko, Valeriy A.; Pershin, Yuriy V.


    Traditional studies of memristive devices have mainly focused on their applications in nonvolatile information storage and information processing. Here, we demonstrate that the third fundamental component of information technologies—the transfer of information—can also be employed with memristive devices. For this purpose, we introduce a metastable memristive circuit. Combining metastable memristive circuits into a line, one obtains an architecture capable of transferring a signal edge from one space location to another. We emphasize that the suggested metastable memristive lines employ only resistive circuit components. Moreover, their networks (for example, Y-connected lines) have an information processing capability.

  14. Electron beam irradiation processing for industrial and medical applications (United States)

    Ozer, Zehra Nur


    In recent years, electron beam processing has been widely used for medical and industrial applications. Electron beam accelerators are reliable and durable equipments that can produce ionizing radiation when it is needed for a particular commercial use. On the industrial scale, accelerators are used to generate electrons in between 0.1-100 MeV energy range. These accelerators are used mainly in plastics, automotive, wire and electric cables, semiconductors, health care, aerospace and environmental industries, as well as numerous researches. This study presents the current applications of electron beam processing in medicine and industry. Also planned study of a design for such a system in the energy range of 200-300 keV is introduced.

  15. Processing and utilization of palm date fruits for edible applications. (United States)

    Kamal-Eldin, Afaf; Hashim, Isameldin B; Mohamed, Ibrahim O


    The date palm tree (Phoenix dactylifra L., family: Palmaceae) is perhaps the oldest and most important fruit crop in the Middle East and North Africa. From this region, the tree spread to other parts of the world and is cultivated in some parts of USA. About 6-7 Million tons of date fruits, belonging to a large variety of cultivars with different characteristics, are produced annually. The date fruit is mainly composed of sugars (invert sugars and/or sucrose) and fiber and, as such, can find a wide range of applications. However, processing applications of the date fruits are limited and new possibilities need to be exploited. This paper reviews the state-of-art knowledge on the compositional and technological aspects and patents pertinent to the processing and utilization of date fruits.

  16. Emerging applications of radiation processing. Proceedings of a technical meeting

    International Nuclear Information System (INIS)


    Approximately 160 gamma irradiators and 1200 electron accelerator based processing units are in operation worldwide. In recent years the IAEA has prepared a directory of industrial gamma irradiators and held several meetings on developments in radiation technology applications. Developments involving the engineering of new sources (both isotope and electrical), high power accelerator applications, etc. have been reported recently, making a review and evaluation of this progress timely. Therefore the IAEA organized a technical meeting in Vienna, Austria, from 28 to 30 April 2003 to review the present situation and the potential contribution of radiation technology to sustainable development. Engineering developments and other features of radiation sources, both isotope and accelerator, were discussed. Recent research has concentrated on three fields: medical and food products, polymers, and environmental pollution control. The stability of radiation sterilized medical implants, as well as the uses of radiation processing for sterilization or decontamination of pharmaceuticals and pharmaceutical raw materials, radiation synthesis and modification of polymers for biomedical applications have been studied. Since separation and enrichment technologies play an important role in product recovery and pollution control, the possibility of radiation synthesis of stimuli-responsive membranes, hydrogels and adsorbents is being investigated. Finally, aside from the technologies for flue gas and wastewater treatment already in use, further research is ongoing on the treatment of organic contaminants in both gaseous and liquid phases. Environmental applications, which also offer new opportunities, should be carefully reviewed to reflect existing regulations and current knowledge. The increasingly serious problem of polyaromatic hydrocarbons (PAH) emissions may be solved in part by the application of radiation technology. This is being studied on a pilot scale for the removal of

  1. Digital Light Processing update: status and future applications (United States)

    Hornbeck, Larry J.


    Digital Light Processing (DLP) projection displays based on the Digital Micromirror Device (DMD) were introduced to the market in 1996. Less than 3 years later, DLP-based projectors are found in such diverse applications as mobile, conference room, video wall, home theater, and large-venue. They provide high-quality, seamless, all-digital images that have exceptional stability as well as freedom from both flicker and image lag. Marked improvements have been made in the image quality of DLP-based projection display, including brightness, resolution, contrast ratio, and border image. DLP-based mobile projectors that weighted about 27 pounds in 1996 now weight only about 7 pounds. This weight reduction has been responsible for the definition of an entirely new projector class, the ultraportable. New applications are being developed for this important new projection display technology; these include digital photofinishing for high process speed minilab and maxilab applications and DLP Cinema for the digital delivery of films to audiences around the world. This paper describes the status of DLP-based projection display technology, including its manufacturing, performance improvements, and new applications, with emphasis on DLP Cinema.

  2. Linear circuits, systems and signal processing: theory and application

    International Nuclear Information System (INIS)

    Byrnes, C.I.; Saeks, R.E.; Martin, C.F.


    In part because of its universal role as a first approximation of more complicated behaviour and in part because of the depth and breadth of its principle paradigms, the study of linear systems continues to play a central role in control theory and its applications. Enhancing more traditional applications to aerospace and electronics, application areas such as econometrics, finance, and speech and signal processing have contributed to a renaissance in areas such as realization theory and classical automatic feedback control. Thus, the last few years have witnessed a remarkable research effort expended in understanding both new algorithms and new paradigms for modeling and realization of linear processes and in the analysis and design of robust control strategies. The papers in this volume reflect these trends in both the theory and applications of linear systems and were selected from the invited and contributed papers presented at the 8th International Symposium on the Mathematical Theory of Networks and Systems held in Phoenix on June 15-19, 1987

  4. Some computer applications and digital image processing in nuclear medicine

    International Nuclear Information System (INIS)

    Lowinger, T.


    Methods of digital image processing are applied to problems in nuclear medicine imaging. The symmetry properties of central nervous system lesions are exploited in an attempt to determine the three-dimensional radioisotope density distribution within the lesions. An algorithm developed by astronomers at the end of the 19th century to determine the distribution of matter in globular clusters is applied to tumors. This algorithm permits the emission-computed-tomographic reconstruction of spherical lesions from a single view. The three-dimensional radioisotope distribution derived by the application of the algorithm can be used to characterize the lesions. The applicability to nuclear medicine images of ten edge detection methods in general usage in digital image processing were evaluated. A general model of image formation by scintillation cameras is developed. The model assumes that objects to be imaged are composed of a finite set of points. The validity of the model has been verified by its ability to duplicate experimental results. Practical applications of this work involve quantitative assessment of the distribution of radipharmaceuticals under clinical situations and the study of image processing algorithms

  5. Novel applications of ionic liquids in materials processing

    International Nuclear Information System (INIS)

    Reddy, Ramana G


    Ionic liquids are mixtures of organic and inorganic salts which are liquids at room temperature. Several potential applications of ionic liquids in the field of materials processing are electrowinning and electrodeposition of metals and alloys, electrolysis of active metals at low temperature, liquid-liquid extraction of metals. Results using 1-butyl-3-methylimidazolium chloride with AlCl 3 at low temperatures yielded high purity aluminium deposits (>99.9% pure) and current efficiencies >98%. Titanium and aluminium were co-deposited with/without the addition of TiCl 4 with up to 27 wt% Ti in the deposit with current efficiencies in the range of 78-85 %. Certain ionic liquids are potential replacements for thermal oils and molten salts as heat transfer fluids in solar energy applications due to high thermal stability, very low corrosivity and substantial sensible heat retentivity. The calculated storage densities for several chloride and fluoride ionic liquids are in the range of 160-210 MJ/m 3 . A 3-D mathematical model was developed to simulate the large scale electrowinning of aluminium. Since ionic liquids processing results in their low energy consumption, low pollutant emissions many more materials processing applications are expected in future.

  6. Quantum Markov processes and applications in many-body systems

    International Nuclear Information System (INIS)

    Temme, P. K.


    This thesis is concerned with the investigation of quantum as well as classical Markov processes and their application in the field of strongly correlated many-body systems. A Markov process is a special kind of stochastic process, which is determined by an evolution that is independent of its history and only depends on the current state of the system. The application of Markov processes has a long history in the field of statistical mechanics and classical many-body theory. Not only are Markov processes used to describe the dynamics of stochastic systems, but they predominantly also serve as a practical method that allows for the computation of fundamental properties of complex many-body systems by means of probabilistic algorithms. The aim of this thesis is to investigate the properties of quantum Markov processes, i.e. Markov processes taking place in a quantum mechanical state space, and to gain a better insight into complex many-body systems by means thereof. Moreover, we formulate a novel quantum algorithm which allows for the computation of the thermal and ground states of quantum many-body systems. After a brief introduction to quantum Markov processes we turn to an investigation of their convergence properties. We find bounds on the convergence rate of the quantum process by generalizing geometric bounds found for classical processes. We generalize a distance measure that serves as the basis for our investigations, the chi-square divergence, to non-commuting probability spaces. This divergence allows for a convenient generalization of the detailed balance condition to quantum processes. We then devise the quantum algorithm that can be seen as the natural generalization of the ubiquitous Metropolis algorithm to simulate quantum many-body Hamiltonians. By this we intend to provide further evidence, that a quantum computer can serve as a fully-fledged quantum simulator, which is not only capable of describing the dynamical evolution of quantum systems, but

  7. Processes and applications of silicon carbide nanocomposite fibers (United States)

    Shin, D. G.; Cho, K. Y.; Jin, E. J.; Riu, D. H.


    Various types of SiC such as nanowires, thin films, foam, and continuous fibers have been developed since the early 1980s, and their applications have been expanded into several new applications, such as for gas-fueled radiation heater, diesel particulate filter (DPF), ceramic fiber separators and catalyst/catalyst supports include for the military, aerospace, automobile and electronics industries. For these new applications, high specific surface area is demanded and it has been tried by reducing the diameter of SiC fiber. Furthermore, functional nanocomposites show potentials in various harsh environmental applications. In this study, silicon carbide fiber was prepared through electrospinning of the polycarbosilane (PCS) with optimum molecular weight distribution which was synthesized by new method adopting solid acid catalyst such as ZSM-5 and γ-Al2O3. Functional elements such as aluminum, titanium, tungsten and palladium easily doped in the precursor fiber and remained in the SiC fiber after pyrolysis. The uniform SiC fibers were produced at the condition of spinning voltage over 20 kV from the PCS solution as the concentration of 1.3 g/ml in DMF/Toluene (3:7) and pyrolysis at 1200°C. Pyrolyzed products were processed into several interesting applications such as thermal batteries, hydrogen sensors and gas filters.

  9. Application of statistical process control and process capability analysis procedures in orbiter processing activities at the Kennedy Space Center (United States)

    Safford, Robert R.; Jackson, Andrew E.; Swart, William W.; Barth, Timothy S.


    Successful ground processing at KSC requires that flight hardware and ground support equipment conform to specifications at tens of thousands of checkpoints. Knowledge of conformance is an essential requirement for launch. That knowledge of conformance at every requisite point does not, however, enable identification of past problems with equipment, or potential problem areas. This paper describes how the introduction of Statistical Process Control and Process Capability Analysis identification procedures into existing shuttle processing procedures can enable identification of potential problem areas and candidates for improvements to increase processing performance measures. Results of a case study describing application of the analysis procedures to Thermal Protection System processing are used to illustrate the benefits of the approaches described in the paper.

  10. Application of Special Cause Control Charts to Green Sand Process

    Directory of Open Access Journals (Sweden)

    Perzyk M.


    Full Text Available Statistical Process Control (SPC based on the well known Shewhart control charts, is widely used in contemporary manufacturing industry, including many foundries. However, the classic SPC methods require that the measured quantities, e.g. process or product parameters, are not auto-correlated, i.e. their current values do not depend on the preceding ones. For the processes which do not obey this assumption the Special Cause Control (SCC charts were proposed, utilizing the residual data obtained from the time-series analysis. In the present paper the results of application of SCC charts to a green sand processing system are presented. The tests, made on real industrial data collected in a big iron foundry, were aimed at the comparison of occurrences of out-of-control signals detected in the original data with those appeared in the residual data. It was found that application of the SCC charts reduces numbers of the signals in almost all cases It is concluded that it can be helpful in avoiding false signals, i.e. resulting from predictable factors.

  11. Application of thermal technologies for processing of radioactive waste

    International Nuclear Information System (INIS)


    The primary objective of this publication is to provide an overview of the various thermal technologies for processing various solid, liquid, organic and inorganic radioactive waste streams. The advantages, limitations and operating experience of various thermal technologies are explained. This publication also goes beyond previous work on thermal processes by addressing the applicability of each technology to national or regional nuclear programmes of specific relative size (major advanced programmes, small to medium programmes, and emerging programmes with other nuclear applications). The most commonly used thermal processing technologies are reviewed, and the key factors influencing the selection of thermal technologies as part of a national waste management strategy are discussed. Accordingly, the structure and content of this publication is intended to assist decision-makers, regulators, and those charged with developing such strategies to identify and compare thermal technologies for possible inclusion in the mix of available, country-specific waste management processes. This publication can be used most effectively as an initial cutting tool to identify whether any given technology will best serve the local waste management strategy in terms of the waste generated, technical complexity, available economic resources, environmental impact considerations, and end product (output) of the technology. If multiple thermal technologies are being actively considered, this publication should be instrumental in comparing the technologies and assisting the user to reach an informed decision based on local needs, economics and priorities. A detailed set of conclusions is provided in Section 7

    Magny, E. de; Berte, M.


    Within the frame of the fast reactors decommissioning, the becoming of contaminated sodium coolant from primary, secondary and auxiliary circuits is an important aspect. The 'NOAH' sodium disposal process, developed by the French Atomic Energy Commission (CEA), is presented as the only process, for destroying large quantities of contaminated sodium, that has attained industrial status. The principles and technical options of the process are described and main advantages such as safety , operating simplicity and compactness of the plant are put forward. The process has been industrially validated in 1993/1994 by successfully reacting the 37 metric tons of primary contaminated sodium from the French Rapsodie experimental reactor. The main outstanding aspects and experience gained from this so called 'DESORA' operation (DEstruction of SOdium from RApsodie) are recalled. Another industrial application concerns the current project for destroying more than 1500 metric tons of contaminated sodium from the British PFR (Prototype Fast Reactor) in Scotland. Although the design is in the continuity of DESORA, it has taken into account the specific requirements of PFR application and the experience feed back from Rapsodie. The main technical options and performances of the PFR sodium reaction unit are presented while mentioning the design evolution. (author)

    Jones, J.E.; Gambill, W.R.; Cooper, R.H.; Fox, E.C.; Fuller, L.C.; Littlefield, C.C.; Silverman, M.D.


    A critical review is presented of the technology and economics for coupling a very high-temperature gas-cooled reactor to a variety of process applications. It is concluded that nuclear steam reforming of light hydrocarbons for coal conversion could be a near-term alternative and that direct nuclear coal gasification could be a future consideration. Thermochemical water splitting appears to be more costly and its availability farther in the future than the coal-conversion systems. Nuclear steelmaking is competitive with the direct reduction of iron ore from conventional coal-conversion processes but not competitive with the reforming of natural gas at present gas prices. Nuclear process heat for petroleum refining, even with the necessary backup systems, is competitive with fossil energy sources. The processing with nuclear heat of oil shale and tar sands is of marginal economic importance. An analysis of peaking power applications using nuclear heat was also made. It is concluded that steam reforming methane for energy storage and production of peaking power is not a viable economic alternative, but that energy storage with a high-temperature heat transfer salt (HTS) is competitive with conventional peaking systems. An examination of the materials required in process heat exchangers is made

    Dong, Baohua; Zhang, Chunmi; Zhuo, Chen


    In the process of environmental design and creation, the design sketch holds a very important position in that it not only illuminates the design's idea and concept but also shows the design's visual effects to the client. In the field of environmental design, computer aided design has made significant improvement. Many types of specialized design software for environmental performance of the drawings and post artistic processing have been implemented. Additionally, with the use of this software, working efficiency has greatly increased and drawings have become more specific and more specialized. By analyzing the application of photoshop image processing software in environmental design and comparing and contrasting traditional hand drawing and drawing with modern technology, this essay will further explore the way for computer technology to play a bigger role in environmental design.

  16. Stochasticity in processes fundamentals and applications to chemistry and biology

    CERN Document Server

    Schuster, Peter


    This book has developed over the past fifteen years from a modern course on stochastic chemical kinetics for graduate students in physics, chemistry and biology. The first part presents a systematic collection of the mathematical background material needed to understand probability, statistics, and stochastic processes as a prerequisite for the increasingly challenging practical applications in chemistry and the life sciences examined in the second part. Recent advances in the development of new techniques and in the resolution of conventional experiments at nano-scales have been tremendous: today molecular spectroscopy can provide insights into processes down to scales at which current theories at the interface of physics, chemistry and the life sciences cannot be successful without a firm grasp of randomness and its sources. Routinely measured data is now sufficiently accurate to allow the direct recording of fluctuations. As a result, the sampling of data and the modeling of relevant processes are doomed t...

    Energy Technology Data Exchange (ETDEWEB)

    Schubach, P. [Oakite Products, Inc., Berkeley Heights, NJ (United States); Gehmecker, H. [Chemetall GmbH, Frankfurt am Main (Germany)


    Pre-treatment processes for automotive applications in Europe are optimized firstly due to the increasing use of aluminum and coated steel for car bodies and parts and secondly due to environmental issues. Prephosphated coated steel, mainly electrogalvanized steel with a trication zinc phosphate layer applied in the steel mill is used by many car manufacturers. Several R and D projects are under way to coat aluminum sheet with inorganic or organic layers to enhance forming, welding and joining properties. Environmental aspects initiated the development of cleaners with biodegradable and alkylphenolethoxylate-free surfactants, liquid grain refiners with longer bath life-time, nickel or nitrite-free zinc phosphate products and chrome-free passivations. All of these products are in use in many automotive body lines except the nickel-free phosphating process which is being tested in OEM parts lines. Details of the processes in a phosphating line are described including a section on phosphating of aluminum.

  18. Mathematical modelling of anaerobic digestion processes: applications and future needs

    DEFF Research Database (Denmark)

    Batstone, Damien J.; Puyol, Daniel; Flores Alsina, Xavier


    of the role of the central carbon catabolic metabolism in anaerobic digestion, with an increased importance of phosphorous, sulfur, and metals as electron source and sink, and consideration of hydrogen and methane as potential electron sources. The paradigm of anaerobic digestion is challenged by anoxygenic...... phototrophism, where energy is relatively cheap, but electron transfer is expensive. These new processes are commonly not compatible with the existing structure of anaerobic digestion models. These core issues extend to application of anaerobic digestion in domestic plant-wide modelling, with the need......Anaerobic process modelling is a mature and well-established field, largely guided by a mechanistic model structure that is defined by our understanding of underlying processes. This led to publication of the IWA ADM1, and strong supporting, analytical, and extension research in the 15 years since...

  19. Applications of nuclear tracer techniques in coastal zone process studies

    International Nuclear Information System (INIS)

    Szymczak, R.


    Nuclear techniques have a wide utility in coastal zone studies. Applications described in this talk include studies of the offshore dispersal of sewage, the migration of sand and sediment, and processes important to the biogeochemical cycling of elements in the marine environment. They are particularly suited to elucidation of the compartmentalisation and rates of processes, both presently occurring and in past times. Many studies are designed to contribute to the scientific basis, or development of engineering concepts, for sustainable development in coastal regions where population densities are high and there are potential conflicts in the exploitation of resources. Other studies are aimed at developing an understanding of specific interactions within coastal ecosystems and the rates at which these processes occur. These radiotracer techniques provide a mechanism of fine tuning concepts and equations (models) in order to achieve a balance between man' s activities and his impact on the environment

  20. Classical and spatial stochastic processes with applications to biology

    CERN Document Server

    Schinazi, Rinaldo B


    The revised and expanded edition of this textbook presents the concepts and applications of random processes with the same illuminating simplicity as its first edition, but with the notable addition of substantial modern material on biological modeling. While still treating many important problems in fields such as engineering and mathematical physics, the book also focuses on the highly relevant topics of cancerous mutations, influenza evolution, drug resistance, and immune response. The models used elegantly apply various classical stochastic models presented earlier in the text, and exercises are included throughout to reinforce essential concepts. The second edition of Classical and Spatial Stochastic Processes is suitable as a textbook for courses in stochastic processes at the advanced-undergraduate and graduate levels, or as a self-study resource for researchers and practitioners in mathematics, engineering, physics, and mathematical biology. Reviews of the first edition: An appetizing textbook for a f...

  1. Grid Computing Application for Brain Magnetic Resonance Image Processing

    International Nuclear Information System (INIS)

    Valdivia, F; Crépeault, B; Duchesne, S


    This work emphasizes the use of grid computing and web technology for automatic post-processing of brain magnetic resonance images (MRI) in the context of neuropsychiatric (Alzheimer's disease) research. Post-acquisition image processing is achieved through the interconnection of several individual processes into pipelines. Each process has input and output data ports, options and execution parameters, and performs single tasks such as: a) extracting individual image attributes (e.g. dimensions, orientation, center of mass), b) performing image transformations (e.g. scaling, rotation, skewing, intensity standardization, linear and non-linear registration), c) performing image statistical analyses, and d) producing the necessary quality control images and/or files for user review. The pipelines are built to perform specific sequences of tasks on the alphanumeric data and MRIs contained in our database. The web application is coded in PHP and allows the creation of scripts to create, store and execute pipelines and their instances either on our local cluster or on high-performance computing platforms. To run an instance on an external cluster, the web application opens a communication tunnel through which it copies the necessary files, submits the execution commands and collects the results. We present result on system tests for the processing of a set of 821 brain MRIs from the Alzheimer's Disease Neuroimaging Initiative study via a nonlinear registration pipeline composed of 10 processes. Our results show successful execution on both local and external clusters, and a 4-fold increase in performance if using the external cluster. However, the latter's performance does not scale linearly as queue waiting times and execution overhead increase with the number of tasks to be executed.

  2. Orthopedic surgery fellowships: the effects of interviewing and how residents establish a rank list. (United States)

    Niesen, Matthew C; Wong, Jeffrey; Ebramzadeh, Edward; Sangiorgio, Sophia; SooHoo, Nelson Fong; Luck, James V; Eckardt, Jeffrey


    The Orthopaedic Fellowship Match was established in 2008 to streamline and improve the process of matching residents and fellowships. The purpose of this study was to quantify the factors that affect the application process and to determine how residents establish a rank list. The Orthopaedic Fellowship Match has improved the ability of residents and programs to consider their options more carefully and to focus on finding the best match. However, this process introduces new factors for all parties involved to consider. The costs of the interview process and time away from service for residents may be larger than anticipated. Ultimately, residents value operative experience and staff members at a fellowship more than all other factors when selecting a fellowship. Copyright 2015, SLACK Incorporated.

The present status of materials and their characteristics and detectors figures-of-merit are presented in detail. In the end, the unique techniques demonstrated for improving/enhancing the performance of pyroelectric detectors are illustrated. Emphasis is placed on recent advances and emerging technologies such as thin-film array devices and novel single crystal sensors.

  4. AOA Approval of ACGME Internship and Residency Training. (United States)

    Duffy, Thomas; Martinez, Bulmaro


    Since the 1970s, the American Osteopathic Association (AOA) has provided a means for osteopathic physicians to apply for approval of their postdoctoral training in programs accredited by the Accreditation Council for Graduate Medical Education (ACGME). Osteopathic physicians who trained in ACGME programs need this approval to meet AOA licensure and board certification requirements. The AOA approves ACGME residency training with several different approval processes. Approval of the first year of postdoctoral training occurs through Resolution 42, specialty approval (for specialties in which the first year of training is part of the residency), or federal or military training approval. For residency training, the AOA verifies successful completion of an ACGME training program before approving the training. The AOA is using customer surveys and online applications to improve the review process for applicants.

  5. A survey of decontamination processes applicable to DOE nuclear facilities

    Energy Technology Data Exchange (ETDEWEB)

    Chen, L.; Chamberlain, D.B.; Conner, C.; Vandegrift, G.F.


    The objective of this survey was to select an appropriate technology for in situ decontamination of equipment interiors as part of the decommissioning of U.S. Department of Energy nuclear facilities. This selection depends on knowledge of existing chemical decontamination methods. This report provides an up-to-date review of chemical decontamination methods. According to available information, aqueous systems are probably the most universally used method for decontaminating and cleaning metal surfaces. We have subdivided the technologies, on the basis of the types of chemical solvents, into acid, alkaline permanganate, highly oxidizing, peroxide, and miscellaneous systems. Two miscellaneous chemical decontamination methods (electrochemical processes and foam and gel systems) are also described. A concise technical description of various processes is given, and the report also outlines technical considerations in the choice of technologies, including decontamination effectiveness, waste handing, fields of application, and the advantages and limitations in application. On the basis of this survey, six processes were identified for further evaluation. 144 refs., 2 tabs.

  6. Application of radiation technology to sewage sludge processing: A review

    International Nuclear Information System (INIS)

    Wang Jianlong; Wang Jiazhuo


    Sewage sludge is unwanted residual solid wastes generated in wastewater treatment and its management is one of the most critical environmental issues of today. The treatment and disposal of sludge contribute a considerable proportion of the cost for running a wastewater treatment plant. The increasing amount of swage sludge and more and more legislative regulation of its disposal have stimulated the need for developing new technologies to process sewage sludge efficiently and economically. One ideal consideration is to recycle it after proper treatment. Radiation technology is regarded to be a promising alternative for its high efficiency in pathogen inactivation, organic pollutants oxidation, odor nuisance elimination and some other characteristics enhancement, which will facilitate the down-stream process of sludge treatment and disposal. Here we present a brief review of application of radiation technology on sewage sludge processing. Some basic information of two currently available irradiation systems and fundamental radiation chemistry are introduced firstly; then the world-wide application of this promising technology is reviewed; various effects of radiation on sludge is discussed in detail; and some concluding remarks are given and some future directions are also proposed

  7. Applications of Ecological Engineering Remedies for Uranium Processing Sites, USA

    Energy Technology Data Exchange (ETDEWEB)

    Waugh, William [Navarro Research and Engineering


    The U.S. Department of Energy (USDOE) is responsible for remediation of environmental contamination and long-term stewardship of sites associated with the legacy of nuclear weapons production during the Cold War in the United States. Protection of human health and the environment will be required for hundreds or even thousands of years at many legacy sites. USDOE continually evaluates and applies advances in science and technology to improve the effectiveness and sustainability of surface and groundwater remedies (USDOE 2011). This paper is a synopsis of ecological engineering applications that USDOE is evaluating to assess the effectiveness of remedies at former uranium processing sites in the southwestern United States. Ecological engineering remedies are predicated on the concept that natural ecological processes at legacy sites, once understood, can be beneficially enhanced or manipulated. Advances in tools for characterizing key processes and for monitoring remedy performance are demonstrating potential. We present test cases for four ecological engineering remedies that may be candidates for international applications.

  9. Processing Techniques and Applications of Silk Hydrogels in Bioengineering

    Directory of Open Access Journals (Sweden)

    Michael Floren


    Full Text Available Hydrogels are an attractive class of tunable material platforms that, combined with their structural and functional likeness to biological environments, have a diversity of applications in bioengineering. Several polymers, natural and synthetic, can be used, the material selection being based on the required functional characteristics of the prepared hydrogels. Silk fibroin (SF is an attractive natural polymer for its excellent processability, biocompatibility, controlled degradation, mechanical properties and tunable formats and a good candidate for the fabrication of hydrogels. Tremendous effort has been made to control the structural and functional characteristic of silk hydrogels, integrating novel biological features with advanced processing techniques, to develop the next generation of functional SF hydrogels. Here, we review the several processing methods developed to prepare advanced SF hydrogel formats, emphasizing a bottom-up approach beginning with critical structural characteristics of silk proteins and their behavior under specific gelation environments. Additionally, the preparation of SF hydrogel blends and other advanced formats will also be discussed. We conclude with a brief description of the attractive utility of SF hydrogels in relevant bioengineering applications.

  10. Traveling Magnetic Field Applications for Materials Processing in Space (United States)

    Grugel, R. N.; Mazuruk, K.; Curreri, Peter A. (Technical Monitor)


    Including the capability to induce a controlled fluid flow in the melt can significantly enrich research on solidification phenomena in a microgravity environment. The traveling magnetic field (TMF) is a promising technique to achieve this goal and is the aim of our ground-based project. In this presentation we will discuss new theoretical as well as experimental results recently obtained by our group. In particular, we experimentally demonstrated efficient mixing of metal alloys in long tubes subjected to TMF during processing. Application of this technique can provide an elegant solution to ensure melt homogenization prior to solidification in a microgravity environment where natural convection is generally absent. Results of our experimental work of applying the TMF technique to alloy melts will be presented. Possible applications of TMF on board the International Space Station will also be discussed.

  12. Ordinary multiplication of distributions. Application to control of economic processes (United States)

    Kim, A. V.; Kormyshev, V. M.; Serova, N. B.; Fitina, L. N.; Kozhakhmetov, A. B.


    There exist many physical and economic models, which cannot be described in terms of usual functions. Such problems require application of the theory of distributions (generalized functions) (P. Antosik, J. Mikusinski, R. Sikorski, 1973; J. F. Colombeau, 1984; A.V. Kim, 2015, 1988; S.L. Sobolev, 1950; L Schwartz, 1950-1951). One of the first and the most important problems of the distribution theory consist in impossibility of defining a multiplication of distribution. The problem is so important that still is in the focus of researchers, because of various applications to nonlinear singular models. In the paper, an ordinary multiplication of generalized functions (distributions) is proposed. The obtained results are applied in a problem of control of economic processes.

    CERN Document Server

    Moridi, Atieh


    This book first presents different approaches to modeling of the cold spray process with the aim of extending current understanding of its fundamental principles and then describes emerging applications of cold spray. In the coverage of modeling, careful attention is devoted to the assessment of critical and erosion velocities. In order to reveal the phenomenological characteristics of interface bonding, severe, localized plastic deformation and material jet formation are studied. Detailed consideration is also given to the effect of macroscopic defects such as interparticle boundaries and subsequent splat boundary cracking on the mechanical behavior of cold spray coatings. The discussion of applications focuses in particular on the repair of damaged parts and additive manufacturing in various disciplines from aerospace to biomedical engineering. Key aspects include a systematic study of defect shape and the ability of cold spray to fill the defect, examination of the fatigue behavior of coatings for structur...

  14. High Throughput Multispectral Image Processing with Applications in Food Science. (United States)

    Tsakanikas, Panagiotis; Pavlidis, Dimitris; Nychas, George-John


    Recently, machine vision is gaining attention in food science as well as in food industry concerning food quality assessment and monitoring. Into the framework of implementation of Process Analytical Technology (PAT) in the food industry, image processing can be used not only in estimation and even prediction of food quality but also in detection of adulteration. Towards these applications on food science, we present here a novel methodology for automated image analysis of several kinds of food products e.g. meat, vanilla crème and table olives, so as to increase objectivity, data reproducibility, low cost information extraction and faster quality assessment, without human intervention. Image processing's outcome will be propagated to the downstream analysis. The developed multispectral image processing method is based on unsupervised machine learning approach (Gaussian Mixture Models) and a novel unsupervised scheme of spectral band selection for segmentation process optimization. Through the evaluation we prove its efficiency and robustness against the currently available semi-manual software, showing that the developed method is a high throughput approach appropriate for massive data extraction from food samples.

  17. Local and distant residence times of contaminants in multi-compartment models. Part II: application to assessing environmental mobility and long-range atmospheric transport. (United States)

    Reid, Liisa; Mackay, Don


    In Part I, the concepts of inherent, local and distant residence times (DRTs) were reviewed as metrics of the extent to which chemical discharges or emissions in one region or box are transported to distant regions. In this second part, the concepts are applied to geographically relevant systems to illustrate their applicability to the assessment of chemicals for long-range transport potential (LRTP). It is shown that the relative ranking of chemicals as characterized by the DRT method is similar to that of the characteristic travel distance concept. A DRT source-receptor matrix is developed that can express the chemical-specific potential of source regions to contaminate a specific receptor region of concern such as the Arctic. The matrix can be modified to identify for a specific source region the likely destinations of emissions as well as to assess the relative vulnerability of regions in the global environment to contaminants of concern.

  18. "Rocking the match": applying and getting into residency. (United States)

    Ziegelstein, Roy C


    Success in life requires talent and skill. But in addition, preparation is critical because it allows a person to use talent and skill to their maximal advantage, putting the person in the best position possible for whatever is planned. Success in the residency application process is more likely if the student keeps this in mind. If a student begins to prepare long before the deadlines and due dates, the process will be easier and things will be more likely to work to his or her advantage. This article is written from the perspective of someone who has evaluated many residency applications and many residency applicants. It is "an insider's view" into the process and provides some tips to medical students as they contemplate the next step after medical school. The points in the article can be remembered with the mnemonic "MRS. POPE," which should allow the student to recall the importance of Mentoring; how to prepare a Résumé; the value of good Scores; the skills involved in Promoting oneself; the role of careful Observation during the interview process; and how to Present oneself and Express interest during and after the visit. Even if the mnemonic cannot be recalled, the student should remember above all that the process of preparing oneself for applying for residency begins the first day of medical school, if not sooner. Hopefully, students can use the information in this manuscript as a recipe for "rocking the match."

    Varshney, Lalit


    Search for better materials and processes has been a part of the evolution of mankind and it still continues to be so as it is being realized that earth's resources are not everlasting and effect of rapid growth on environment may adversely affect the future development. Sustainable development is the only choice for today for long term survival. Better quality and high functional materials, made by superior technologies are being demanded by the society. Radiation processing technology has significantly contributed to meet the expectation of the people in providing superior products and processes while preserving the environment. Processes are being developed where resources are fully utilized with maximum advantages and little disturbance to the environment. More than 1500 electron beam accelerators and about 500 Gamma Irradiators are presently in use and many are being deployed for radiation processing of medical supplies, pharmaceuticals and herbal materials, treat effluents and preserve food and agricultural products and several industrial products. DAE has an ambitious plan to deploy radiation technology for societal benefits in India. In the presentations some interesting applications of Radiation Processing Technology will be discussed which includes (1) Radiation Processing of Cashew Apple fruit for bio-ethanol production (2) High Energy Battery separators (3) Plant Growth Promoters and (4) Tunable biodegradability. The discussion would reveal how a waste product like cashew apple can be converted to useful materials and advanced materials like HEB separators and Tunable Biodegradable films can be made using radiation technology. Use of radiation de-polymerized polysaccharides in some experiments have shown unexpected increase in agriculture output giving new concepts to increase the productivity. (author)

  11. A software engineering process for safety-critical software application

    International Nuclear Information System (INIS)

    Kang, Byung Heon; Kim, Hang Bae; Chang, Hoon Seon; Jeon, Jong Sun


    Application of computer software to safety-critical systems in on the increase. To be successful, the software must be designed and constructed to meet the functional and performance requirements of the system. For safety reason, the software must be demonstrated not only to meet these requirements, but also to operate safely as a component within the system. For longer-term cost consideration, the software must be designed and structured to ease future maintenance and modifications. This paper presents a software engineering process for the production of safety-critical software for a nuclear power plant. The presentation is expository in nature of a viable high quality safety-critical software development. It is based on the ideas of a rational design process and on the experience of the adaptation of such process in the production of the safety-critical software for the shutdown system number two of Wolsung 2, 3 and 4 nuclear power generation plants. This process is significantly different from a conventional process in terms of rigorous software development phases and software design techniques, The process covers documentation, design, verification and testing using mathematically precise notations and highly reviewable tabular format to specify software requirements and software requirements and software requirements and code against software design using static analysis. The software engineering process described in this paper applies the principle of information-hiding decomposition in software design using a modular design technique so that when a change is required or an error is detected, the affected scope can be readily and confidently located. it also facilitates a sense of high degree of confidence in the 'correctness' of the software production, and provides a relatively simple and straightforward code implementation effort. 1 figs., 10 refs.

  12. Research on application of computer technologies in jewelry process

    Directory of Open Access Journals (Sweden)

    Junbo Xia


    Full Text Available Jewelry production is a process of precious raw materials and low losses in processing. The traditional manual mode is unable to meet the needs of enterprises in reality, while the involvement of computer technology can just solve this practical problem. At present, the problem of restricting the application for computer in jewelry production is mainly a failure to find a production model that can serve the whole industry chain with the computer as the core of production. This paper designs a “synchronous and diversified” production model with “computer aided design technology” and “rapid prototyping technology” as the core, and tests with actual production cases, and achieves certain results, which are forward-looking and advanced.

    CERN Document Server

    Ellis, Matthew; Christofides, Panagiotis D


    This book presents general methods for the design of economic model predictive control (EMPC) systems for broad classes of nonlinear systems that address key theoretical and practical considerations including recursive feasibility, closed-loop stability, closed-loop performance, and computational efficiency. Specifically, the book proposes: Lyapunov-based EMPC methods for nonlinear systems; two-tier EMPC architectures that are highly computationally efficient; and EMPC schemes handling explicitly uncertainty, time-varying cost functions, time-delays and multiple-time-scale dynamics. The proposed methods employ a variety of tools ranging from nonlinear systems analysis, through Lyapunov-based control techniques to nonlinear dynamic optimization. The applicability and performance of the proposed methods are demonstrated through a number of chemical process examples. The book presents state-of-the-art methods for the design of economic model predictive control systems for chemical processes. In addition to being...

  17. Application of low intensity ultrasonics to cheese manufacturing processes. (United States)

    Benedito, J; Carcel, J A; Gonzalez, R; Mulet, A


    Ultrasound has been used to non-destructively assess the quality of many foods such as meat, fish, vegetables and dairy products. This paper addresses the applications of low intensity ultrasonics in the cheese manufacturing processes and highlights the areas where ultrasonics could be successfully implemented in the future. The decrease of ultrasonic attenuation during the renneting process can be used to determine the optimum cut time for cheese making. The ultrasonic velocity increases during maturation for those types of cheese that become harder during this manufacturing stage, thus being an indicator of the maturity degree. Moreover, ultrasonic measurements could be linked to sensory parameters. From the ultrasonic velocity measurements at two different temperatures, it is possible to assess cheese composition, thus allowing an improvement in the quality and uniformity of cheese commercialization. In addition, in pulse-echo mode it is possible to detect cracked pieces due to abnormal fermentations and also to assess the distance of the crack from the surface.

  18. Neural networks for process control and optimization: two industrial applications. (United States)

    Bloch, Gérard; Denoeux, Thierry


    The two most widely used neural models, multilayer perceptron (MLP) and radial basis function network (RBFN), are presented in the framework of system identification and control. The main steps for building such nonlinear black box models are regressor choice, selection of internal architecture, and parameter estimation. The advantages of neural network models are summarized: universal approximation capabilities, flexibility, and parsimony. Two applications are described in steel industry and water treatment, respectively, the control of alloying process in a hot dipped galvanizing line and the control of a coagulation process in a drinking water treatment plant. These examples highlight the interest of neural techniques, when complex nonlinear phenomena are involved, but the empirical knowledge of control operators can be learned.

  20. Applications of Natural Language Processing in Biodiversity Science

    Directory of Open Access Journals (Sweden)

    Anne E. Thessen


    A computer can handle the volume but cannot make sense of the language. This paper reviews and discusses the use of natural language processing (NLP and machine-learning algorithms to extract information from systematic literature. NLP algorithms have been used for decades, but require special development for application in the biological realm due to the special nature of the language. Many tools exist for biological information extraction (cellular processes, taxonomic names, and morphological characters, but none have been applied life wide and most still require testing and development. Progress has been made in developing algorithms for automated annotation of taxonomic text, identification of taxonomic names in text, and extraction of morphological character information from taxonomic descriptions. This manuscript will briefly discuss the key steps in applying information extraction tools to enhance biodiversity science.

    This report gives the results of considerations on industrial heat and technology processes (in chemistry, steelmaking, etc.) from the point of view of possible ways, technical conditions and nuclear safety requirements for the use of high temperature reactors in these processes. Possible variants of energy-technological diagrams of nuclear-steelmaking, methane steam-reforming reaction and other processes, taking into account the specific character of nuclear fuel are also given. Technical possibilities and economic conditions of the usage of different types of high temperature reactors (gas cooled reactors and reactors which have other means of transport of nuclear heat) in heat processes are examined. The report has an analysis of the problem, that arises with the application of nuclear reactors in energy-technological plants and an evaluation of solutions of this problem. There is a reason to suppose that we will benefit from the use of high temperature reactors in comparison with the production based on high quality fossil fuel [ru

  3. Simulation of deposed dose and application of image processing

    International Nuclear Information System (INIS)

    Dadi, A.; Fahli, A.


    In gamma radiation processing, the photons from radioactive isotopes, are absorbed in matter where they lost a part or the whole energy they process. On every point P of the material irradiated, the absorbed dose (D) is the deposed energy in the volume (dV) (centred in P) per the mass (Dm) of this volume. The radiations effects on every point of material it directly depend on the locally deposed energy. For technical applications it very important to know how the dose is deposed in irradiated material. Because of the random aspect of each process who may released in material ( Photoelectric effect, Compton diffusion and pair production (e sup +, e sup -..) and the arbitrary geometries can be treated, we use in this work, the Monte Carlo simulation, to describe the phenomenon and reproduce it at all in computer during the irradiation processing for photons with energies above a few KeV to a several MeV in any element compound or mixture. The rate dose is then calculated at every point P(x,y,z,) and restored as real data file in first time,and transformed to bytes data file and finally shown as a digital image in high resolution 16 colors allowing an analysis of the dose variation in material 2 figs., 2 refs.

  4. Application of phototrophic biofilms: from fundamentals to processes. (United States)

    Strieth, D; Ulber, R; Muffler, K


    Biotechnological production of valuables by microorganisms is commonly achieved by cultivating the cells as suspended solids in an appropriate liquid medium. However, the main portion of these organisms features a surface-attached growth in their native habitats. The utilization of such biofilms shows significant challenges, e.g. concerning control of pH, nutrient supply, and heat/mass transfer. But the use of biofilms might also enable novel and innovative production processes addressing robustness and strength of the applied biocatalyst, for example if variable conditions might occur in the process or a feedstock (substrate) is changed in its composition. Besides the robustness of a biofilm, the high density of the immobilized biocatalyst facilitates a simple separation of the catalyst and the extracellular product, whereas intracellular target compounds occur in a concentrated form; thus, expenses for downstream processing can be drastically reduced. While phototrophic organisms feature a fabulous spectrum of metabolites ranging from biofuels to biologically active compounds, the low cell density of phototrophic suspension cultures is still limiting their application for production processes. The review is focusing on pro- and eukaryotic microalgae featuring the production of valuable compounds and highlights requirements for their cultivation as phototrophic biofilms, i.e. setup as well as operation of biofilm reactors, and modeling of phototrophic growth.

  5. Financial burden associated with the residency match in neurological surgery. (United States)

    Agarwal, Nitin; Choi, Phillip A; Okonkwo, David O; Barrow, Daniel L; Friedlander, Robert M


    OBJECTIVE Application for a residency position in neurosurgery is a highly competitive process. Visiting subinternships and interviews are integral parts of the application process that provide applicants and programs with important information, often influencing rank list decisions. However, the process is an expensive one that places significant financial burden on applicants. In this study, the authors aimed to quantify expenses incurred by 1st-year neurosurgery residents who matched into a neurosurgery residency program in 2014 and uncover potential trends in expenses. METHODS A 10-question survey was distributed in partnership with the Society of Neurological Surgeons to all 1st-year neurosurgery residents in the United States. The survey asked respondents about the number of subinternships, interviews, and second looks (after the interview) attended and the resultant costs, the type of program match, preferences for subinternship interviews, and suggestions for changes they would like to see in the application process. In addition to compiling overall results, also examined were the data for differences in cost when stratifying for region of the medical school or whether the respondent had contact with the program they matched to prior to the interview process (matched to home or subinternship program). RESULTS The survey had a 64.4% response rate. The mean total expenses for all components of the application process were US $10,255, with interview costs comprising the majority of the expenses (69.0%). No difference in number of subinternships, interviews, or second looks attended, or their individual and total costs, was seen for applicants from different regions of the United States. Respondents who matched to their home or subinternship program attended fewer interviews than respondents who had no prior contact with their matched program (13.5 vs 16.4, respectively, p = 0.0023) but incurred the same overall costs (mean $9774 vs $10,566; p = 0

    The Continuous Process Control package (CPC) is one of the components of the CERN Unified Industrial Control System framework (UNICOS). As a part of this framework, UNICOS-CPC provides a well defined library of device types, a methodology and a set of tools to design and implement industrial control applications. The new CPC version uses the software factory UNICOS Application Builder (UAB) to develop CPC applications. The CPC component is composed of several platform oriented plug-ins (PLCs and SCADA) describing the structure and the format of the generated code. It uses a resource package where both, the library of device types and the generated file syntax, are defined. The UAB core is the generic part of this software, it discovers and calls dynamically the different plug-ins and provides the required common services. In this paper the UNICOS CPC6 package is introduced. It is composed of several plug-ins: the Instance generator and the Logic generator for both, Siemens and Schneider PLCs, the SCADA generator (based on PVSS) and the CPC wizard as a dedicated plug-in created to provide the user a friendly GUI (Graphical User Interface). A tool called UAB Bootstrap will manage the different UAB components, like CPC, and its dependencies with the resource packages. This tool guides the control system developer during the installation, update and execution of the UAB components. (authors)

  8. Arabic text preprocessing for the natural language processing applications

    International Nuclear Information System (INIS)

    Awajan, A.


    A new approach for processing vowelized and unvowelized Arabic texts in order to prepare them for Natural Language Processing (NLP) purposes is described. The developed approach is rule-based and made up of four phases: text tokenization, word light stemming, word's morphological analysis and text annotation. The first phase preprocesses the input text in order to isolate the words and represent them in a formal way. The second phase applies a light stemmer in order to extract the stem of each word by eliminating the prefixes and suffixes. The third phase is a rule-based morphological analyzer that determines the root and the morphological pattern for each extracted stem. The last phase produces an annotated text where each word is tagged with its morphological attributes. The preprocessor presented in this paper is capable of dealing with vowelized and unvowelized words, and provides the input words along with relevant linguistics information needed by different applications. It is designed to be used with different NLP applications such as machine translation text summarization, text correction, information retrieval and automatic vowelization of Arabic Text. (author)

  9. Modelling of transport processes in porous media for energy applications

    Energy Technology Data Exchange (ETDEWEB)

    Kangas, M.


    Flows in porous media are encountered in many branches of technology. In these phenomena, a fluid of some sort is flowing through porous matrix of a solid medium. Examples of the fluid are water, air, gas and oil. The solid matrix can be soil, fissured rock, ceramics, filter paper, etc. The flow is in many cases accompanied by transfer of heat or solute within the fluid or between the fluid and the surrounding solid matrix. Chemical reactions or microbiological processes may also be taking place in the system. In this thesis, a 3-dimensional computer simulation model THETA for the coupled transport of fluid, heat, and solute in porous media has been developed and applied to various problems in the field of energy research. Although also applicable to porous medium applications in general, the version of the model described and used in this work is intended for studying the transport processes in aquifers, which are geological formations containing groundwater. The model highlights include versatile input and output routines, as well as modularity which, for example, enables an easy adaptation of the model for use as a subroutine in large energy system simulations. Special attention in the model development has been attached to high flow conditions, which may be present in Nordic esker aquifers located close to the ground surface. The simulation model has been written with FORTRAN 77 programming language, enabling a seamless operation both in PC and main frame environments. For PC simulation, a special graphic user interface has been developed. The model has been used with success in a wide variety of applications, ranging from basic thermal analyses to thermal energy storage system evaluations and nuclear waste disposal simulations. The studies have shown that thermal energy storage is feasible also in Nordic high flow aquifers, although at the cost of lower recovery temperature level, usually necessitating the use of heat pumps. In the nuclear waste studies, it

  10. Metabolic processes of Methanococcus maripaludis and potential applications. (United States)

    Goyal, Nishu; Zhou, Zhi; Karimi, Iftekhar A


    Methanococcus maripaludis is a rapidly growing, fully sequenced, genetically tractable model organism among hydrogenotrophic methanogens. It has the ability to convert CO2 and H2 into a useful cleaner energy fuel (CH4). In fact, this conversion enhances in the presence of free nitrogen as the sole nitrogen source due to prolonged cell growth. Given the global importance of GHG emissions and climate change, diazotrophy can be attractive for carbon capture and utilization applications from appropriately treated flue gases, where surplus hydrogen is available from renewable electricity sources. In addition, M. maripaludis can be engineered to produce other useful products such as terpenoids, hydrogen, methanol, etc. M. maripaludis with its unique abilities has the potential to be a workhorse like Escherichia coli and S. cerevisiae for fundamental and experimental biotechnology studies. More than 100 experimental studies have explored different specific aspects of the biochemistry and genetics of CO2 and N2 fixation by M. maripaludis. Its genome-scale metabolic model (iMM518) also exists to study genetic perturbations and complex biological interactions. However, a comprehensive review describing its cell structure, metabolic processes, and methanogenesis is still lacking in the literature. This review fills this crucial gap. Specifically, it integrates distributed information from the literature to provide a complete and detailed view for metabolic processes such as acetyl-CoA synthesis, pyruvate synthesis, glycolysis/gluconeogenesis, reductive tricarboxylic acid (RTCA) cycle, non-oxidative pentose phosphate pathway (NOPPP), nitrogen metabolism, amino acid metabolism, and nucleotide biosynthesis. It discusses energy production via methanogenesis and its relation to metabolism. Furthermore, it reviews taxonomy, cell structure, culture/storage conditions, molecular biology tools, genome-scale models, and potential industrial and environmental applications. Through the

  11. Teaching residents to write a research paper. (United States)

    Coleridge, S T


    Medical writing and publications are important in developing a scholarly basis for residency programs and in providing a learning experience for both resident and faculty mentors. Residency directors must provide the stimulus and support for both faculty and residents' varied creative activities. This support manifests itself in a commitment to scholarly activity (including a dedicated research person), the procurement of available research materials, the establishment of a process or plan for beginning a research project, and the development of a method for rewarding or recognizing faculty and residents who produce scholarly works. Some osteopathic residency programs may need to train faculty in research skills at the same time that residents are learning to write. Trained faculty are better models and coaches for residents engaged in research. Beginning with a fundamental, but disciplined, writing program, both faculty and residents may learn methods for sharing new knowledge or acquiring those skills necessary to critically analyze the medical literature.

  12. Protocol for a process-oriented qualitative evaluation of the Waltham Forest and East London Collaborative (WELC) integrated care pioneer programme using the Researcher-in-Residence model. (United States)

    Eyre, Laura; George, Bethan; Marshall, Martin


    The integration of health and social care in England is widely accepted as the answer to fragmentation, financial concerns and system inefficiencies, in the context of growing and ageing populations with increasingly complex needs. Despite an expanding body of literature, there is little evidence yet to suggest that integrated care can achieve the benefits that its advocates claim for it. Researchers have often adopted rationalist and technocratic approaches to evaluation, treating integration as an intervention rather than a process. Results have usually been of limited use to practitioners responsible for health and social care integration. There is, therefore, a need to broaden the evidence base, exploring not only what works but also how integrated care can most successfully be implemented and delivered. For this reason, we are carrying out a formative evaluation of the Waltham Forest and East London Collaborative (WELC) integrated care pioneer programme. Our expectation is that this will add value to the literature by focusing on the processes by which the vision and objectives of integrated care are translated through phases of development, implementation and delivery from a central to a local perspective, and from a strategic to an operational perspective. The qualitative and process-oriented evaluation uses an innovative participative approach-the Researcher-in-Residence model. The evaluation is underpinned by a critical ontology, an interpretive epistemology and a critical discourse analysis methodology. Data will be generated using interviews, observations and documentary gathering. Emerging findings will be interpreted and disseminated collaboratively with stakeholders, to enable the research to influence and optimise the effective implementation of integrated care across WELC. Presentations and publications will ensure that learning is shared as widely as possible. The study has received ethical approval from University College London's Research Ethics

    Meger, Robert; Fernsler, Richard; Leonhardt, Darrin; Manheimer, Wallace; Murphy, Donald; Pechacek, Robert


    Large area sheet plasmas have been produced at the Naval Research Laboratory for radar beam steering applications.(R. F. Fernsler, et al., Phys. Plasmas 5, 2137 (1998)) In these experiments a 3-5 kilovolt, <50 mA/cm^2, 1 cm x 60 cm area pulsed electron beam confined by a 150-250 Gauss magnetic field, is injected into a 30-100 mTorr background gas. The beam electrons ionize the gas, producing a 1.5-3 cm thick, 60 cm x 60 cm planar plasma. Uniform electron densities of up to Ne 5x10^12 cm-3 with Te < 1eV have been produced. The combination of low T_e, high N_e, and large area may be ideal for materials processing.(R. A. Meger, et al., Proc. 4th Inter. Wkshp. on Adv. Plasma Tools, PEUG/NCCAVS (Millbrae, CA, May 1998), p. 235.) Initial tests have shown a rapid isotropic etch of a patterned photoresist using an oxygen plasma. This paper will discuss the plasma production mechanism and present initial experimental results on surface processing. Plans for production of a Large Area Plasma Processing System (LAPPS) will be presented.

    Experiments in high-energy physics (HEP) and related fields often impose constraints and challenges on data acquisition systems. As a result, these systems are implemented as unique mixtures of custom and commercial-off-the-shelf electronics (COTS), involving and connecting radiation-hard devices, large high-performance networks, and computing farms. FELIX, the Frontend Link Exchange, is a new PC-based general purpose data routing device for the data-acquisition system of the ATLAS experiment at CERN. Performance is a very crucial point for devices like FELIX, which have to be capable of processing tens of gigabyte of data per second. Thus it is important to understand the performance limitations for typical workloads on modern hardware. We present an analysis of a packet processing algorithm that is used in FELIX, and show how the PC system's memory architecture plays a key factor in the overall data throughput achieved by the application. Finally, we present optimizations that increase the processing throug...

  16. On Markovian traffic with applications to TES processes

    Directory of Open Access Journals (Sweden)

    David L. Jagerman


    Full Text Available Markov processes are an important ingredient in a variety of stochastic applications. Notable instances include queueing systems and traffic processes offered to them. This paper is concerned with Markovian traffic, i.e., traffic processes whose inter-arrival times (separating the time points of discrete arrivals form a real-valued Markov chain. As such this paper aims to extend the classical results of renewal traffic, where interarrival times are assumed to be independent, identically distributed. Following traditional renewal theory, three functions are addressed: the probability of the number of arrivals in a given interval, the corresponding mean number, and the probability of the times of future arrivals. The paper derives integral equations for these functions in the transform domain. These are then specialized to a subclass, TES+, of a versatile class of random sequences, called TES (Transform-Expand-Sample, consisting of marginally uniform autoregressive schemes with modulo-1 reduction, followed by various transformations. TES models are designed to simultaneously capture both first-order and second-order statistics of empirical records, and consequently can produce high-fidelity models. Two theoretical solutions for TES+ traffic functions are derived: an operator-based solution and a matric solution, both in the transform domain. A special case, permitting the conversion of the integral equations to differential equations, is illustrated and solved. Finally, the results are applied to obtain instructive closed-form representations for two measures of traffic burstiness: peakedness and index of dispersion, elucidating the relationship between them.

  17. [Application of image processing technique in scoliosis detection]. (United States)

    Lu, Donghui; Xu, Chaojing; Sun, Jinai


    Scoliosis, the abnormal lateral curvature of the spine, is an idiopathic disease often suffered by teenagers. Normally medical doctors use X-rays to measure the Cobb angle, and then assess the severity of scoliosis with it. In this paper, we point out the superiorities of image processing technique through analyzing the existing methods in the diagnosis of scoliosis. Two kinds of image processing technique are mainly introduced for scoliosis detection. The moiré stripe images show an asymmetric deformation pattern between the left-hand side and the right-hand side of human back, and these associate with Cobb angle to detect scoliosis. In order to check scoliosis through accurate three-dimensional surface features of human back, we in the second technique use different optical imaging methods to reconstruct the three-dimensional surface model of the patient's back, and extract the characteristics of the reconstructive human back to diagnose the disease. Both approaches tried to describe symmetry discrimination of human back and correlated it with the Cobb angles. Finally, we look forward to the future development in the application of image processing technique for scoliosis detection.

  18. The effect of a daily application of a 0.05% chlorhexidine oral rinse solution on the incidence of aspiration pneumonia in nursing home residents: a multicenter study. (United States)

    Hollaar, Vanessa R Y; van der Putten, Gert-Jan; van der Maarel-Wierink, Claar D; Bronkhorst, Ewald M; de Swart, Bert J M; Creugers, Nico H J


    Dysphagia and potential respiratory pathogens in the oral biofilm are risk factors for aspiration pneumonia in nursing home residents. The aim of the study was to examine if the daily application of 0.05% chlorhexidine oral rinse solution is effective in reducing the incidence of aspiration pneumonia in nursing home residents with dysphagia. Associations between background variables (age, gender, dysphagia severity, care dependency, medication use, number of medical diagnoses, teeth and dental implants, and wearing removable dentures) and the incidence of aspiration pneumonia were also examined. This study is a multicenter study in which for 1 year participants with dysphagia in the intervention group received the usual oral hygiene care with the addition of a 0.05% chlorhexidine oral rinse solution, whereas participants in the control group received only oral hygiene care. Data of 103 participants in 17 nursing homes were analyzed. Survival analysis showed no significant difference in the incidence of pneumonia between both groups (Cox regression, HR = 0.800; 95% CI [0.368-1.737], p = 0.572). Cox regression analysis for Functional Oral Intake Scale (FOIS)-level showed a significant risk of the incidence of pneumonia (HR = 0.804; 95% CI [0.656-0.986], p = 0.036). After adjustment for Group and FOIS-level, Cox multivariate proportional hazard regression analysis showed that the variables age, gender, Care-dependency Scale-score (CDS) number of diseases, medication use, number of teeth, and the presence of dental implants or removable dentures were not significantly associated with the incidence of pneumonia.

    Manufacturers widely recognize testing as a major factor in the cost, producability, and delivery of product in the $100 billion integrated circuit business: {open_quotes}The rapid development of VLSI using sub-micron CMOS technology has suddenly exposed traditional test techniques as a major cost factor that could restrict the development of VLSI devices exceeding 512 pins an operating frequencies above 200 MHz.{close_quotes} -- 1994 Semiconductor Industry Association Roadmap, Design and Test, Summary, pg. 43. This problem increases dramatically for stockpile electronics, where small production quantities make it difficult to amortize the cost of increasingly expensive testers. Application of multiple ICs in Multi-Chip Modules (MCM) greatly multiplies testing problems for commercial and defense users alike. By traditional test methods, each new design requires custom test hardware and software and often dedicated testing equipment costing millions of dollars. Also, physical properties of traditional test systems often dedicated testing equipment costing millions of dollars. Also, physical properties of traditional test systems limit capabilities in testing at-speed (>200 MHz), high-impedance, and high-accuracy analog signals. This project proposed a revolutionary approach to these problems: replace the multi-million dollar external test system with an inexpensive test system integrated onto the product wafer. Such a methodology enables testing functions otherwise unachievable by conventional means, particularly in the areas of high-frequency, at-speed testing, high impedance analog circuits, and known good die assessment. The techniques apply specifically to low volume applications, typical of Defense Programs, where testing costs represent an unusually high proportional of product costs, not easily amortized.

  20. Application of the Hydroecological Integrity Assessment Process for Missouri Streams (United States)

    Kennen, Jonathan G.; Henriksen, James A.; Heasley, John; Cade, Brian S.; Terrell, James W.


    Natural flow regime concepts and theories have established the justification for maintaining or restoring the range of natural hydrologic variability so that physiochemical processes, native biodiversity, and the evolutionary potential of aquatic and riparian assemblages can be sustained. A synthesis of recent research advances in hydroecology, coupled with stream classification using hydroecologically relevant indices, has produced the Hydroecological Integrity Assessment Process (HIP). HIP consists of (1) a regional classification of streams into hydrologic stream types based on flow data from long-term gaging-station records for relatively unmodified streams, (2) an identification of stream-type specific indices that address 11 subcomponents of the flow regime, (3) an ability to establish environmental flow standards, (4) an evaluation of hydrologic alteration, and (5) a capacity to conduct alternative analyses. The process starts with the identification of a hydrologic baseline (reference condition) for selected locations, uses flow data from a stream-gage network, and proceeds to classify streams into hydrologic stream types. Concurrently, the analysis identifies a set of non-redundant and ecologically relevant hydrologic indices for 11 subcomponents of flow for each stream type. Furthermore, regional hydrologic models for synthesizing flow conditions across a region and the development of flow-ecology response relations for each stream type can be added to further enhance the process. The application of HIP to Missouri streams identified five stream types ((1) intermittent, (2) perennial runoff-flashy, (3) perennial runoff-moderate baseflow, (4) perennial groundwater-stable, and (5) perennial groundwater-super stable). Two Missouri-specific computer software programs were developed: (1) a Missouri Hydrologic Assessment Tool (MOHAT) which is used to establish a hydrologic baseline, provide options for setting environmental flow standards, and compare past and

    Wilson, V.


    Data were gathered through site visits to 100 industrial plants. The site specific data suggests several possible near term market opportunities for solar thermal energy systems. Plants using electricity as their primary fuel for industrial process heat were identified, on the basis of their high fuel prices, as attractive early entry markets for solar energy. Additional opportunities were reflected in plants that had accomplished much of their conservation plans, or bad sizeable percentages of their operating budgets committed to energy expenses. A suitability analysis identified eleven industrial plants as highly suitable for solar thermal applications, they included producers of fluid milk, pottery, canned and bottled soft drinks, fabricated structural metal, refined petroleum, aluminum cans, chrome and nickel plating and stamped frame metal and metal finishings.

  5. Application of statistical process control to qualitative molecular diagnostic assays

    LENUS (Irish Health Repository)

    O'Brien, Cathal P.


    Modern pathology laboratories and in particular high throughput laboratories such as clinical chemistry have developed a reliable system for statistical process control (SPC). Such a system is absent from the majority of molecular laboratories and where present is confined to quantitative assays. As the inability to apply SPC to an assay is an obvious disadvantage this study aimed to solve this problem by using a frequency estimate coupled with a confidence interval calculation to detect deviations from an expected mutation frequency. The results of this study demonstrate the strengths and weaknesses of this approach and highlight minimum sample number requirements. Notably, assays with low mutation frequencies and detection of small deviations from an expected value require greater sample numbers to mitigate a protracted time to detection. Modeled laboratory data was also used to highlight how this approach might be applied in a routine molecular laboratory. This article is the first to describe the application of SPC to qualitative laboratory data.

  7. Radiation Processing of Natural Polymers for Industrial Applications

    International Nuclear Information System (INIS)

    Hegazy, E.A.


    Radiation induced degradation technology is a new and promising application of ionizing radiation to develop viscose, pulp, paper, food preservation, pharmaceutical production, and natural bioactive agents industries. Controlling the degree of degradation, uniform molecular weight distribution, saving achieved in the chemicals (used in conventional methods) on a cost basis, and environmentally friendly process are the beneficial effects of using radiation technology in these industries. However, for some development countries such technology is not economic. Therefore, a great effort should be done to reduce the cost required for such technologies. One of the principle factors for reducing the cost is achieving the degradation at low irradiation doses. The addition of some additives such as potassium per-sulfate (KPS), ammonium per-sulfate (APS), or H 2 O 2 to natural polymers (carboxy-methylcellulose (CMC), chitosan, carrageenan and Na-alginate) during irradiation process accelerates their degradation. The highest degradation rate of polysaccharides obtained when APS was used. The end product of irradiated CMC, chitosan, carrageenan and Na-alginate may be used as food additive or benefited in agricultural purposes. On the other hand, radiation crosslinking of PAAm or PNIPAAm is affected by the presence of natural polymer like CMC-Na and carrageenan due to their degradability which could be controlled according to its concentration in the bulk medium and irradiation dose. Accordingly, the gel content, thermo-sensitivity (LCST) and swelling properties of PNIPAAm based natural polymers could be controlled. The swelling of the prepared copolymer hydrogels was investigated for its possible use in personal care articles particularly diapers or as carriers for drug delivery systems. The prepared crosslinked copolymers possessed high and fast swelling properties in simulated urine media and the swelling ratios of CMC-Na /PAAm gels in urine are acceptable for diaper

    Meinert, Lene; Broge, Eva Honnens de Lichtenberg; Bejerholm, Camilla; Jensen, Kirsten


    With increasing consumer interest in functional foods, proteins from slaughterhouse side streams can offer interesting application opportunities in this respect. Worldwide, increasing numbers of people are suffering from hypertension and protein deficiency. Hydrolyzed proteins of animal origin may show ACE-inhibitory activity, which is central to the treatment of hypertension. Furthermore, the protein content of, for example, meat products increases markedly through the addition of hydrolyzed proteins, and these protein-rich products are of interest to those suffering from protein deficiency. Through a series of analyses, six selected hydrolysates were analyzed for their application potential in the Danish meat product saveloy. Hydrolyzed pig rectum and bovine diaphragm showed the highest ACE-inhibitory activities, and these activities were maintained in the processed saveloys. The ACE-inhibitory activities could not readily be explained by the amino acid profile. The content of N-compounds in the saveloys increased with increasing addition of hydrolysate, with little difference between the added hydrolysates. A sensory panel assessed the saveloys with added porcine rectum (8%), bovine diaphragm (8%), and bovine heart (4% and 8%) as having the strongest off-flavors (chemical flavor). No increase in salty taste resulting from the addition of hydrolysates was detected in the saveloys. Finally, the consumers found the saveloys too mild in flavor and recommended the addition of more spices.

    The Isotope Division of BARC is equipped with a 2-MeV electron beam (EB) accelerator and a 70,000 Ci Cobalt-60 source: these are mainly utilized to develop technologies of interest to our industries and needs. These include development of polyethylene 'O' rings having dimensional stability above the melting point, radiation degradation of PTFE and enhancement of colour in diamonds. The viscose rayon industry is an important industry in India. This industry faces stiff regulations from environmental pollution control agencies primarily due to the emission of toxic sulphur containing gases, and is in search of ways to reduce the pollution levels associated with the process. The irradiation of cellulose with ionizing radiation results in cellulose activation and reduction in the degree of polymerization (DP). There is a keen interest in utilizing radiation technology in viscose rayon production. We have utilized the 2-MeV electron beam accelerator for reducing the degree of polymerization (DP) of paper pulp. Laboratory scale tests have been carried out to standardize the conditions for processing of pulp having desired degree of polymerization. Our studies show that the use of irradiated pulp can significantly reduce the consumption of CS 2 and be beneficial in reducing pollution associated with the process. An electron-beam irradiation based process has been developed to convert the PTFE waste into a low molecular weight (1x10 4 -1x10 5 ) PTFE powder that can be easily processed into a fine micropowder having industrial demand. Even carbon or metal filled PTFE has been recycled using this process. The conventional method of crosslinking linear polymers by thermo-clinical method leads to the formation of homogeneously crosslinked materials which are extremely slow for industrial applications. Electron beam irradiation has been used to create inhomogeneous crosslinking of a temperature-sensitive polymer- poly(vinyl methyl ether)(PVME) so as to produce a fast response

  17. Isolation and processing of silk proteins for biomedical applications. (United States)

    Kundu, Banani; Kurland, Nicholas E; Yadavalli, Vamsi K; Kundu, Subhas C


    Silk proteins of silkworms are chiefly composed of core fibroin protein and glycoprotein sericin that glues fibroin. Unique mechanical properties, cyto-compatibility and controllable biodegradability facilitate the use of fibroin in biomedical applications. Sericin serves as additive in cosmetic and food industries, as mitotic factor in cell culture media, anti-cancerous drug, anticoagulant and as biocompatible coating. For all these uses; aqueous solutions of silk proteins are preferred. Therefore, an accurate understanding of extraction procedure of silk proteins from their sources is critical. A number of protocols exist, amongst which it is required to settle a precise and easy one with desired yield and least down-stream processing. Here, we report extraction of proteins employing methods mentioned in literature using cocoons of mulberry and nonmulberry silks. This study reveals sodium carbonate salt-boiling system is the most efficient sericin extraction procedure for all silk variants. Lithium bromide is observed as the effective fibroin dissolution system for mulberry silk cocoons; whereas heterogeneous species-dependent result is obtained in case of nonmulberry species. We further show the effect of common post processing on nanoscale morphology of mulberry silk fibroin films. This knowledge eases the adoption and fabrication of silk biomaterials in devices and therapeutic delivery systems. Copyright © 2014 Elsevier B.V. All rights reserved.

  19. Nanoemulsion: process selection and application in cosmetics--a review. (United States)

    Yukuyama, M N; Ghisleni, D D M; Pinto, T J A; Bou-Chacra, N A


    In recent decades, considerable and continuous growth in consumer demand in the cosmetics field has spurred the development of sophisticated formulations, aiming at high performance, attractive appearance, sensorial benefit and safety. Yet despite increasing demand from consumers, the formulator faces certain restrictions regarding the optimum equilibrium between the active compound concentration and the formulation base taking into account the nature of the skin structure, mainly concerning to the ideal penetration of the active compound, due to the natural skin barrier. Emulsion is a mixture of two immiscible phases, and the interest in nanoscale emulsion has been growing considerably in recent decades due to its specific attributes such as high stability, attractive appearance and drug delivery properties; therefore, performance is expected to improve using a lipid-based nanocarrier. Nanoemulsions are generated by different approaches: the so-called high-energy and low-energy methods. The global overview of these mechanisms and different alternatives for each method are presented in this paper, along with their benefits and drawbacks. As a cosmetics formulation is reflected in product delivery to consumers, nanoemulsion development with prospects for large-scale production is one of the key attributes in the method selection process. Thus, the aim of this review was to highlight the main high- and low-energy methods applicable in cosmetics and dermatological product development, their specificities, recent research on these methods in the cosmetics and consideration for the process selection optimization. The specific process with regard to inorganic nanoparticles, polymer nanoparticles and nanocapsule formulation is not considered in this paper. © 2015 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

  20. Early resident-to-resident physics education in diagnostic radiology. (United States)

    Kansagra, Akash P


    The revised ABR board certification process has updated the method by which diagnostic radiology residents are evaluated for competency in clinical radiologic physics. In this work, the author reports the successful design and implementation of a resident-taught physics course consisting of 5 weekly, hour-long lectures intended for incoming first-year radiology residents in their first month of training. To the author's knowledge, this is the first description of a course designed to provide a very early framework for ongoing physics education throughout residency without increasing the didactic burden on faculty members. Twenty-six first-year residents spanning 2 academic years took the course and reported subjective improvement in their knowledge (90%) and interest (75%) in imaging physics and a high level of satisfaction with the use of senior residents as physics educators. Based on the success of this course and the minimal resources required for implementation, this work may serve as a blueprint for other radiology residency programs seeking to develop revised physics curricula.
