Resumen

Abstract Background Procedural skill is predicated on knowledge. We used a previously validated test to evaluate the impact of a web-based education program on medical residents' knowledge of 2 advanced medical procedures. Methods We enrolled 210 internal medicine residents at 3 residency programs in a randomized, controlled, educational trial. Study participants completed a 20-item, validated online test of their knowledge of central venous and arterial line (CVL and AL, respectively) placement at baseline and after performing their next 2 procedures (test 1 and test 2). Between test 1 and test 2, participants were randomized to online educational material for CVL insertion, AL insertion, both, or neither. The primary outcome of the study was the difference in test scores between test 1 and test 2 by randomization group. Results Though residents in the baseline cohort were confident about their knowledge of procedural technique, their mean test scores were low (62% and 58% in the CVL and AL tests, respectively). Baseline test score correlated with the number of prior procedures performed. Sixty-five residents completed all 3 CVL tests, and 85 residents completed all 3 AL tests. Access to the web-based procedure education was associated with a significant improvement in scores for both the CVL test (effect size, d = 0.25, P = .01) and AL test (d = 0.52, P < .001). Conclusions Web-based procedure training improves knowledge of procedures to a significantly greater extent than performing the procedure alone. Web-based curricula can effectively supplement other methods of skill development.

Resumen

The Excised Teat Assay is an in vitro germicidal activity assay for evaluation of bovine teat sanitizers. The rinse procedure of this assay was modified and compared to the standard method. The rinse modification used an ultrasonic cleaner to vibrate the quencher solution to remove bacteria from excised teats after challenge. In alternating trials, bacteria were rinsed from teats by the standard procedure or by the ultrasonic procedure. A 1% iodine based teat sanitizer, a chlorhexidine based teat sanitizer, and a negative control were used in the study. Staphylococcus aureus (ATCC 29740) was used as the challenge organism. No significant differences were obtained by analysis of variance when comparing procedures or in comparing procedures within treatments when an experienced technician conducted the procedure. When an inexperienced technician conducted the procedure, significant differences were obtained between procedures and within treatments when comparing procedures. The modified rinse procedure provided more consistent results than the standard rinse procedure when used by an inexperienced technician.

Resumen

A Texas Department of Transportation study performed by the Texas Transportation Institute was undertaken with a goal of providing methods to assure the quality of cold-applied, asphalt-stabilized maintenance mixtures. Test procedures and acceptance criteria were developed for hot-mix, cold-laid asphalt concrete patching mixtures. Two specific objectives were to develop a test procedure to simulate approximately six months of stockpile-aging and a test procedure to quantify workability of maintenance mixtures. The protocol developed is designed to estimate the relative ability of a maintenance mixture to retain adequate workability after outdoor stockpile storage. This protocol could be useful as part of a specification to promote quality. Two test procedures were evaluated regarding their potential to quantify the workability of maintenance mixtures: a triaxial test and an unconfined compression test. Test results indicated that both procedures provide a relatively good measure of workability before and after aging. Two laboratory aging procedures were evaluated for their ability to predict workability of a stockpiled maintenance mixture after six months of field aging. Procedure A appeared to provide a reasonable approximation of six months of field aging.

Resumen

ABSTRACT Objectives To assess clinical skills of interns in selected procedures using direct observation of procedural skills (DOPS) To assess the change in procedural skills among students who received a structured feedback on DOPS. Materials and methods The study was interventional and conducted between December 2015 and February 2016 at the Department of Obstetrics and Gynaecology of Sree Narayana Institute of Medical Sciences, Ernakulam, Kerala, India. In the study, investigator observed the trainee performing a practical procedure within the workplace and recorded a rating for each competency on the assessment form. Feedback was given expanding on the reasons for any ratings of development required and makes practical suggestions for any remedial steps. The intern is reassessed for the same procedure at a later stage and the impact on skills is scored. Then the structured feedback is provided, and later on again the score on skills obtained by DOPS are compared between pre- and post-values by Wilcoxon-signed rank test. Results The average of pre- and post-feedback values were compared by Wilcoxon signed rank test. The p-value calculated was <0.001, which is significant. None of the interns were competent to perform the procedure before feedback; 80% of them needed more practice and 20% needed supervision. After feedback, 53.3% achieved competency and 46.7% achieved competency needing supervision; 93.3% of interns regarded feedback as superior quality, while 6.7% regarded as satisfactory. Conclusion Direct observation of procedural skills can be used to assess clinical skills of interns in selected procedures and it brings changes in procedural skills among students who received a structured feedback on DOPS.

Resumen

Background Medical institutions are under increased economic pressure to schedule elective surgeries efficiently to contain the costs of surgical services. Surgical scheduling is complicated by variability inherent in the duration of surgical procedures. Modeling that variability, in turn, provides a mechanism to generate accurate time estimates. Accurate time estimates are important operationally to improve operating room utilization and strategically to identify surgeons, procedures, or patients whose duration of surgeries differ from what might be expected. Methods The authors retrospectively studied 40,076 surgical cases (1,580 Current Procedural Terminology-anesthesia combinations, each with a case frequency of five or more) from a large teaching hospital, and attempted to determine whether the distribution of surgical procedure times more closely fit a normal or a log-normal distribution. The authors tested goodness-of-fit to these data for both models using the Shapiro-Wilk test. Reasons, in practice, the Shapiro-Wilk test may reject the fit of a log-normal model when in fact it should be retained were also evaluated. Results The Shapiro-Wilk test indicates that the log-normal model is superior to the normal model for a large and diverse set of surgeries. Goodness-of-fit tests may falsely reject the log-normal model during certain conditions that include rounding errors in procedure times, large sample sizes, untrimmed outliers, and heterogeneous mixed populations of surgical procedure times. Conclusions The authors recommend use of the log-normal model for predicting surgical procedure times for Current Procedural Terminology-anesthesia combinations. The results help to legitimize the use of log transforms to normalize surgical procedure times before hypothesis testing using linear statistical models or other parametric statistical tests to investigate factors affecting the duration of surgeries.

Resumen

El grado de compactación de los suelos se evalúa a través de dos parámetros: su peso específico seco máximo (γdmáx) y su humedad óptima (wopt), los cuales se pueden determinar en el laboratorio a través de diversos métodos. Una de las técnicas de mayor uso a nivel mundial es el ensayo Proctor estándar. El procedimiento clásico de este ensayo establece la construcción de una curva de compactación utilizando una sola porción de suelo que se compacta varias veces durante todo el procedimiento. Sin embargo, en la ejecución habitual de esta prueba ha surgido la variante de utilizar varias porciones de suelo en lugar de una sola. El objetivo de esta investigación es aportar información acerca de las diferencias en los resultados obtenidos entre estas dos variantes de la prueba Proctor estándar. Para lograrlo, en un primer grupo de ensayos se determinaron los parámetros óptimos de compactación de dos suelos diferentes del estado de Tabasco siguiendo el procedimiento clásico del ensayo Proctor Estándar. Estos resultados sirvieron de control. A continuación, en un segundo grupo de ensayos y para los mismos suelos, se repitieron las pruebas Proctor estándar pero utilizando varias porciones de suelo en lugar de una sola, esto con la finalidad de que cada porción solo se compactara una vez. Todos los ensayos Proctor se realizaron por triplicado y los resultados se ajustaron mediante una línea polinómica. Comparada con los resultados del ensayo Proctor estándar clásico, la variante que utiliza varias porciones de suelo generó un descenso de alrededor del 1% en los va-lores de los pesos específicos secos máximos, y aumentos en las humedades óptimas en torno al 1.3%. Estas diferencias se originan debido al proceso de preparación de las muestras de suelo en la variante del ensayo Proctor

Resumen

The growing demand for high quality soybean [Glycine max (L.) Merrill] seeds requires a precise seed quality control system from the seed industry. One way to accomplish this is by improving vigor testing. Cold test has been traditionally employed for corn seeds. However, it has also been used for other seed crops such as cotton (Gossypium spp.), soybean (Glycine Max), dry bean (Phaseolus vulgaris) and pea (Pisum sativum). This study was carried out with the objective of adjusting an alternative procedure for the cold test to determine soybean seed vigor. Six commercial soybean seed lots of the cultivar BRS 133 were used. The physiological potential of the seed lots was evaluated by germination on paper towel and sand box, seedling field emergence, tetrazolium, accelerated aging and electrical conductivity tests. Seed moisture content was also determined. The temperature used for the cold test procedures was 10ºC during five days. Four cold test procedures were evaluated: i) plastic boxes with soil; ii) rolled paper towel with soil; iii) rolled paper towel without soil, and iv) an alternative procedure, using rolled paper towel without soil under cold water. A completely randomized experimental design with eight replications was used and the means were compared by the Tukey test (p = 0.05). To verify the dependence between the alternative test and others single linear correlation was used. All cold test procedures had similar coefficients of variation (CV), highlighting that rolled paper towel with soil and the alternative procedure had the best performance, with an average of 94% and 93% normal seedlings and CV of 3.2% and 3.6%, respectively. The alternative procedure has satisfactory results for estimating soybean seed vigor, yielding consistent results compared to the traditional procedure.

Resumen

BackgroundMeasuring patient experience is important for evaluating the quality of patient care, identifying aspects requiring improvement and optimising patient outcomes. Patient Reported Experience Measures (PREMs) should, ideally, be patient derived, however no such PREMs for gastrointestinal (GI) endoscopy exist. This study explored the experiences of patients undergoing GI endoscopy and CT colonography (CTC) in order to: identify aspects of care important to them; determine whether the same themes are relevant across investigative modalities; develop the framework for a GI endoscopy PREM.MethodsPatients aged ≥18 years who had undergone oesophagogastroduodenoscopy (OGD), colonoscopy or CTC for symptoms or surveillance (but not within the national bowel cancer screening programme) in one hospital were invited to participate in semi-structured interviews. Recruitment continued until data saturation. Inductive thematic analysis was undertaken.Results35 patients were interviewed (15 OGD, 10 colonoscopy, 10 CTC). Most patients described their experience chronologically, and five ‘procedural stages’ were evident: before attending for the test; preparing for the test; at the hospital, before the test; during the test; after the test. Six themes were identified: anxiety; expectations; choice & control; communication & information; comfort; embarrassment & dignity. These were present for all three procedures but not all procedure stages. Some themes were inter-related (eg, expectations & anxiety; communication & anxiety).ConclusionWe identified six key themes encapsulating patient experience of GI procedures and these themes were evident for all procedures and across multiple procedure stages. These findings will be used to inform the development of the Newcastle ENDOPREM™.

Resumen

Electrical-performance test (hereafter referred to as E-test) has always been one of the difficulties in final testing procedures for semiconductor. The accuracy, rapidity and generality are difficult to achieve in the E-test. This paper proposes a test method based on the characteristics of the E-test workstation of test handler for semiconductor, in which the whole test procedure is divided into two terminals: the control and the test terminal. The control terminal is integrated into the control system of test handler, while the test terminal is independently designed with generality for different semiconductor products. To achieve an ideal performance, the parallel work trait of E-test in this method is discussed. Finally, the method has been successfully implemented on the test handler for semiconductor in actual production.

Resumen

The aim of the present study is to evaluate the effect of swallowing type (dry versus wet) on the outcome of a nine-step inflation/deflation tympanometric Eustachian tubefunction (ETF) test in healthy adults.Fourteen normal healthy volunteers, between 19 and 28 years of age, were included in the study. The nine-step test was performed in two different test procedures: (1) test with dry swallows (dry test procedure) and (2) test with liquid swallows (wet test procedure). If the equilibration of middle-ear (ME) pressure was successful in all the steps of the nine-step test, ETF was considered ‘Good’. Otherwise, the test was considered ‘Poor’, and the test was repeated at a second session.In the dry test procedure, ETF was ‘Good’ in 21 ears at the first session and in 24 ears after the second session (p > 0.05). However, in the wet test procedure, ETF was ‘Good’ in 13 ears at the first session and in 21 ears after the second session (p < 0.05).At the first session, ETF was ’Good’ in 21 and 13 ears in the dry and wet test procedures, respectively. The difference was statistically significant (p < 0.05). However, after the second session, the overall number of ears with ‘Good’ tubal function was almost the same in both test procedures (24 ears at dry test procedures versus 21 ears at wet test procedures;p > 0.05).Dry swallowing seems to be more effective for the equilibration of ME pressure. Thus, a single-session dependent evaluation of ETF may be efficient for the dry test procedure of the nine-step test. Swallowing with water may be easier for subjects, but a repetition of the test at a second session may be necessary when the test result is ‘Poor’.

Resumen

This paper proposes a new procedure for testing semiconductor random access memories (RAMs). The test procedure detects simultaneously present functional faults such as stuck-at faults, transition faults and coupling faults and requires 19N operations, which is an improvement over conventional procedures. Thus testing time is reduced by the smaller number of operations of the test procedure, test generation and applications are simplified by the linear address marching.

Resumen

The undrained shear strength (su) of a clay is not a constant. In particular, su values of a clay evaluated by different test procedures are different because these tests may have different stress states, stress histories, degrees of sampling disturbance, and strain rates. This study constructs the multivariate probability distribution of su from various test procedures based on a large clay database. This multivariate distribution provides an estimation of the normalized undrained shear strength based on four factors: test mode, overconsolidation ratio, strain rate, and plasticity. Once this multivariate distribution is constructed, interesting questions can be answered systematically using simple Bayesian analysis, e.g., given the su value for one test procedure, what is the updated mean and coefficient of variation of the su value for another test procedure?

Resumen

BACKGROUND: Colon cancer screening, including colonoscopy, lags behind other forms of cancer screening for participation rates. The intrinsic nature of the endoscopic procedure may be an important barrier that limits patients from finding this test acceptable and affects willingness to undergo screening. With colon cancer screening programs emerging in Canada, test characteristics and their impact on acceptance warrant consideration.OBJECTIVES: To measure the acceptability of colonoscopy and define factors that contribute to procedural acceptability, in relation to another invasive gastrointestinal scope procedure, gastroscopy.PATIENTS AND METHODS: Consecutive patients undergoing a colonoscopy (n=55) or a gastroscopy (n=33) were recruited. Their procedural experience was evaluated and compared pre-endoscopy, immediately before testing and postendoscopy. Questionnaires were used to capture multiple domains of the endoscopy experience and patient characteristics.RESULTS: Patient scope groups did not differ preprocedurally for general or procedure-specific anxiety. However, the colonoscopy group did anticipate more pain. Those who had a gastroscopy demonstrated higher preprocedural acceptance than those who had a colonoscopy. The colonoscopy group had a significant decrease in scope concerns and anxiety postprocedurally. As well, they reported less pain than they anticipated. Regardless, postprocedurally, the colonoscopy group’s acceptance did not increase significantly, whereas the gastroscopy group was almost unanimous in their test acceptance. The best predictor of pretest acceptability of colonoscopy was anticipated pain.CONCLUSIONS: The findings indicate that concerns that relate specifically to colonoscopy, including anticipated pain, influence acceptability of the procedure. However, the experience of a colonoscopy does not lead to improved test acceptance, despite decreases in procedural anxiety and pain. Patients’ preprocedural views of the test are most important and should be addressed directly to potentially improve participation in colonoscopy.

Resumen

Soil samples were collected from 14 long-term field experiments in south-western Australia to which several amounts of superphosphate or phosphate rock had been applied in a previous year. The samples were analysed for phosphorus (P) by the Colwell sodium bicarbonate procedure, presently used in Western Australia, and the Mehlich 3 procedure, being assessed as a new multi-element test for the region. For the Mehlich procedure, the concentration of total and inorganic P in the extract solution was measured. The soil test values were related to yields of crops and pasture measured later on in the year in which the soil samples were collected.The Mehlich 3 procedures (Mehlich 3 total and Mehlich 3 inorganic soil test P values) were similar, with the total values mostly being slightly larger. For soil treated with superphosphate, for each year of each experiment: (i) Mehlich 3 values were closely correlated with Colwell values; and (ii) the relationship between plant yield and soil test P (the soil P test calibration) was similar for the Colwell and Mehlich 3 procedures. However, for soil treated with phosphate rock, the Colwell procedure consistently produced lower soil test P values than the Mehlich 3 procedure, and the calibration relating plant yield to soil test P was different for the Colwell and Mehlich 3 procedures, indicating, for soils treated with phosphate rock, separate calibrations are required for the 2 procedures. We conclude that for soils of south-western Australia treated with superphosphate (most of the soils), the Mehlich 3 procedure can be used instead of the Colwell procedure to measure soil test P, providing support for the Mehlich 3 procedure to be developed as the multi-element soil test for the region.

Resumen

Abstract Background Accurate anesthesiology procedure code data are essential to quality improvement, research, and reimbursement tasks within anesthesiology practices. Advanced data science techniques, including machine learning and natural language processing, offer opportunities to develop classification tools for Current Procedural Terminology codes across anesthesia procedures. Methods Models were created using a Train/Test dataset including 1,164,343 procedures from 16 academic and private hospitals. Five supervised machine learning models were created to classify anesthesiology Current Procedural Terminology codes, with accuracy defined as first choice classification matching the institutional-assigned code existing in the perioperative database. The two best performing models were further refined and tested on a Holdout dataset from a single institution distinct from Train/Test. A tunable confidence parameter was created to identify cases for which models were highly accurate, with the goal of at least 95% accuracy, above the reported 2018 Centers for Medicare and Medicaid Services (Baltimore, Maryland) fee-for-service accuracy. Actual submitted claim data from billing specialists were used as a reference standard. Results Support vector machine and neural network label-embedding attentive models were the best performing models, respectively, demonstrating overall accuracies of 87.9% and 84.2% (single best code), and 96.8% and 94.0% (within top three). Classification accuracy was 96.4% in 47.0% of cases using support vector machine and 94.4% in 62.2% of cases using label-embedding attentive model within the Train/Test dataset. In the Holdout dataset, respective classification accuracies were 93.1% in 58.0% of cases and 95.0% among 62.0%. The most important feature in model training was procedure text. Conclusions Through application of machine learning and natural language processing techniques, highly accurate real-time models were created for anesthesiology Current Procedural Terminology code classification. The increased processing speed and a priori targeted accuracy of this classification approach may provide performance optimization and cost reduction for quality improvement, research, and reimbursement tasks reliant on anesthesiology procedure codes.

Resumen

The Florida Department of Transportation uses long-established test procedures to determine the maximum specific gravity (Gmm) and bulk specific gravity (Gmb) of asphalt mixtures and the bulk specific gravity (Gsb) of aggregates. The CoreLok, a vacuum-sealing device that can be used to determine these properties, was evaluated by the department for these test procedures. With respect to the Gmm test procedure, for mixtures containing nonabsorptive granites, the CoreLok determined results equivalent to those of the department's test procedure. However, for mixtures containing absorptive limestones, the CoreLok determined higher Gmm values than did the department's test procedure. The apparent reason for the discrepancy is that the CoreLok does not determine a saturated surface dry condition of the sample. With respect to the aggregate specific gravity test procedures, the CoreLok provided test results equivalent to the department's test procedure for the nonabsorptive fine aggregates only. For the absorptive fine aggregates and all of the coarse aggregates, the CoreLok determined Gsb test results significantly different from those of the department's test procedures. The CoreLok may be suitable for determining Gmb for coarse-graded compacted specimens with high porosity and air voids. There are concerns with the accuracy of the CoreLok results because of the bridging effect of the plastic bag over the large surface voids and because of the CoreLok's significant underestimation of the specific gravity of a solid aluminum cylinder.

Resumen

To compute norms from reference group test scores, continuous norming is preferred over traditional norming. A suitable continuous norming approach for continuous data is the use of the Box–Cox Power Exponential model, which is found in the generalized additive models for location, scale, and shape. Applying the Box–Cox Power Exponential model for test norming requires model selection, but it is unknown how well this can be done with an automatic selection procedure. In a simulation study, we compared the performance of two stepwise model selection procedures combined with four model-fit criteria (Akaike information criterion, Bayesian information criterion, generalized Akaike information criterion (3), cross-validation), varying data complexity, sampling design, and sample size in a fully crossed design. The new procedure combined with one of the generalized Akaike information criterion was the most efficient model selection procedure (i.e., required the smallest sample size). The advocated model selection procedure is illustrated with norming data of an intelligence test.

Resumen

Summary Objectives : We reintroduce an exact Mantel-Haenszel (MH) procedure for meta-analysis with binary endpoints which is expected to workespeciallywell i sparse data, e.g., in meta-analyses of safety or adverse events. Methods : The performance of the exact MH procedure in terms of empirical size and power is compared to the asymptotic MH and to the two standard procedures (fixed effects and random effects model) in a simulation study. We illustrate the methods with a metaanalysis of postoperative stroke occurrence after offpump or on-pump surgery in coronary artery bypass grafting. Results : We find that in almost all situations the asymptotic MH procedure outperforms its competitors; especially the standard methods yield poor results in terms of power and size. Conclusions : There is no need to use the reintroduced exact MH procedure; the asymptotic MH procedure will be sufficient in most practical situations. The standard methods (fixed effects and random effects model) should not be used in the sparse data situation.

Resumen

This article presents an item response model for characterizing test-compromise that enables the estimation of item-preview and score-gain distributions observed in on-demand high-stakes testing programs. Model parameters and posterior distributions are estimated by Markov Chain Monte Carlo (MCMC) procedures. Results of a simulation study suggest that when at least some of the items taken by a small sample of test takers are known to be secure (uncompromised), the procedure can provide useful summaries of test-compromise and its impact on test scores. The article includes discussions of operational use of the proposed procedure, possible model violations and extensions, and application to computerized adaptive testing.

Resumen

AbstractAntimicrobial coatings are typically tested for their activity and effectiveness based on an artificial procedure, the standard JIS Z 2801 (or ISO 22196). The test samples are contaminated with a predetermined concentration of bacteria and covered with a sterile film. Due to the artificial structure of this process, however, there is always the question of the validity in the practical application of these surfaces and how comparable this germ-reducing effect is to currently common disinfection measures. Therefore, we developed a more realistic test procedure in our laboratory. The test samples are inoculated and incubated at standard room conditions. To compare the antimicrobial activity to standard cleaning procedures also disinfection and wipe controls were performed. The results show that the antimicrobial test patterns we use have a strong efficacy. This could be shown reproducibly both with the standard method JIS Z 2801 as well as with our new test procedure.

Resumen

Abstract The paper presents test procedures designed for application-specific integrated circuit (ASIC) CMOS VLSI chip prototype that implements a synchronized oscillator neural network with a matrix size of 32×32 for object detecting in binary images. Networks of synchronized oscillators are recently developed tool for image segmentation and analysis. This paper briefly introduces synchronized oscillators network. Basic chip analog building blocks with their test procedures and measurements results are presented. In order to do measurements, special basic building blocks test structures have been implemented in the chip. It let compare Spectre simulations results to measurements results. Moreover, basic chip analog building blocks measurements give precious information about their imperfections caused by MOS transistor mismatch. This information is very usable during design and improvement of a special setup for chip functional tests. Improvement of the setup is a digitally assisted analog technique. It is an original idea of oscillators tuning procedure used during chip prototype testing. Such setup, oscillators tuning procedure and segmentation of sample binary images are presented

Resumen

This paper presents the field tests conducted as part of activity to establish the vehicle accelerated corrosion test procedure in Malaysia, initiated by the national car manufacturer company, PROTON, Malaysia. Vehicle accelerated corrosion test is a combination of corrosion exposures and durability cycles to accelerate the corrosion process and detect potential failures that may occur during in-service conditions. PROTON conducts the vehicle accelerated corrosion test at external test centres in overseas. However, due to the different climatic of test location, some of the corrosion problems were found to be varied and many did not address the actual corrosion problems detected in Malaysia markets. Hence, the primary aim of this study is to establish a suitable corrosion driving procedure to accommodate the hot and humid environment using facilities in PROTON Test Track. Three corrosion driving procedures were designed based on the number of corrosion exposures and designated as Field Tests 1, 2 and 3. Analysis ruled out that Field Test 3 provides moderate corrosion rate of 0.077-0.842 mm/year and potentially to be the best suited for accelerated corrosion test procedure in Malaysia due to its close replication of actual cosmetic corrosion behaviour observed in Malaysia.

Resumen

The Burr type XII (BurrXII) distribution is very flexible for modeling and has earned much attention in the past few decades. In this study, the maximum likelihood estimation method and two Bayesian estimation procedures are investigated based on constant-stress accelerated life test (ALT) samples, which are obtained from the doubly truncated three-parameter BurrXII distribution. Because computational difficulty occurs for maximum likelihood estimation method, two Bayesian procedures are suggested to estimate model parameters and lifetime quantiles under the normal use condition. A Markov Chain Monte Carlo approach using the Metropolis–Hastings algorithm via Gibbs sampling is built to obtain Bayes estimators of the model parameters and to construct credible intervals. The proposed Bayesian estimation procedures are simple for practical use, and the obtained Bayes estimates are reliable for evaluating the reliability of lifetime products based on ALT samples. Monte Carlo simulations were conducted to evaluate the performance of these two Bayesian estimation procedures. Simulation results show that the second Bayesian estimation procedure outperforms the first Bayesian estimation procedure in terms of bias and mean squared error when users do not have sufficient knowledge to set up hyperparameters in the prior distributions. Finally, a numerical example about oil-well pumps is used for illustration.

Resumen

An ELISA test and two routine culture procedures have been compared in their ability to detect Listeria spp. in food products and swabs of pig tonsils. The culture procedures used were those recommended by the Food and Drug Administration (FDA) and United States Department of Agriculture (USDA). One hundred samples of minced beef, artificially inoculated with Listeria monocytogenes, together with 149 naturally contaminated samples of minced beef, pig tonsil, pig feed and soft, whitemolded, blue-veined cheese were tested by the three methods. The USDA procedure proved to be the most sensitive detection method when samples of artificially contaminated meat containing less than 3 colony forming units (CFU) of L. monocytogenes per gram were examined. In samples where the L. monocytogenes count was above 3 CFU per gram, the ELISA test and the USDA-detection procedure proved to be equally sensitive. When naturally contaminated samples were examined, the sensitivity of the ELISA test was 92% and the specificity 80%. The detection limit of the ELISA test for demonstration of L. monocytogenes in pure cultures was found to be approximately 106 CFU per ml. The corresponding detection limit of the culture procedure was calculated to be approximately 104 CFU per ml.

Resumen

The adequacy of the directional and envelope procedures for the design of the main wind force resisting system is not well understood. The purpose of this study is to evaluate the directional and envelope procedures based on wind tunnel test data for a set of low-rise enclosed buildings with gable-shaped roofs in open terrain (Exposure C). The base shear force and the conditional reliability index are used to determine the adequacy of the procedures. The base shear was compared to the design base shear in each direction based on the horizontal component of the wind load on the wall and roof. The reliability index, β conditional on the occurrence of the design wind speed was computed for a range of system capacities. The main findings are (1) the directional procedure produced a larger design base shear compared to the envelope procedure, primarily due to the difference in external pressure coefficients, (2) the directional procedure provided a higher β, and (3) the envelope procedure provided a β that did not meet the standard target β equal to 3.0 for the main wind force resisting systems with low variability in capacity, but neither procedure met the standard target β for the main wind force resisting systems with high variability in capacity.
