Pallet fire test for steel drum storage on wooden pallets  

SciTech Connect

A fire test was conducted by the Martin Marietta PORTS Fire Protection Engineering Department on October 3, 1991. This test was designed and set up to simulate a proposed storage configuration. The array consisted of 55-gallon steel drums, filled with noncombustible waste material, placed on wooden pallets stacked three tiers high. Results from the test served as the basis for determining the fire protection requirements for this type of storage. Data acquired from the test indicated that relatively high temperatures were obtained from the ignition source. These readings, taken during short durations throughout the test, were recorded from digital readouts connected to individual thermocouples. The test demonstrated that the wooden pallets did not significantly ignite and basically self-extinguished once the ignition source was consumed. Based upon these findings, storage of this type may be placed in the high bay (70 foot ceilings) sprinklered areas. This is providing that good housekeeping is implemented, large ignition sources are not allowed to be stored or parked in the area, and flammable and combustible liquids and solids are not permitted within the storage zones. The area shall also be designated as a {open_quotes}NO SMOKING{close_quotes} area.

Robot Palletizing Work Cell Simulation  

NSDL National Science Digital Library

The purpose of this project is to design a fully functional automated palletizing work cell that will simulate real-world palletizing of two different size bottles in a classroom environment. Successful completion of this project is based on the following components working together in a system: the bottle feeder with a pneumatic actuator, two photoelectric sensors, a conveyor, a programmable logic controller (PLC), and a robot. All the components are integrated to perform a unit task of palletizing. The process begins when a pneumatic actuator pushes a bottle from the tray of the bottle feeder onto the conveyor belt. The conveyor belt then transports the bottle to the inspection station, where two photoelectric sensors are mounted to detect the bottle and determine its size. One of the sensors sends the signal to stop the conveyor while the other sensor prompts the robot to start palletizing.

STABILITY EVALUATION OF METAL CASK ATTACHED TO A TRANSFER PALLET DURING LONG-PERIOD SEISMIC MOTIONS  

NASA Astrophysics Data System (ADS)

Rocking behavior of unfixed body is affected by center of mass, material coefficient of restitution and so on. 2/5 scale metal cask model considering these parameter was used for seismic test to evaluate stability of grounding metal cask attached to a transfer pallet under the influence of long-period earthquake motion. The newest knowledge from seismic test indicates seismic motion with high velocity over 100 kine not always cause the raise of response velocity of metal cask because of energy consumption by cask sliding and impact deformation of concrete. And new estimation method (called "Window energy spectrum method") of earthquake response spectrum gives suitable evaluation of response energy.

Patterning pallet arrays for cell selection based on high-resolution measurements of fluorescent biosensors  

PubMed Central

Pallet arrays enable cells to be separated while they remain adherent to a surface and provide a much greater range of cell selection criteria relative to that of current technologies. However there remains a need to further broaden cell selection criteria to include dynamic intracellular signaling events. To demonstrate the feasibility of measuring cellular protein behavior on the arrays using high resolution microscopy, the surfaces of individual pallets were modified to minimize the impact of scattered light at the pallet edges. The surfaces of the three-dimensional pallets on an array were patterned with a coating such as fibronectin using a customized stamping tool. Micropatterns of varying shape and size were printed in designated regions on the pallets in single or multiple steps to demonstrate the reliability and precision of patterning molecules on the pallet surface. Use of a fibronectin matrix stamped at the center of each pallet permitted the localization of H1299 and mouse embryonic fibroblast (MEF) cells to the pallet centers and away from the edges. Compared to pallet arrays with fibronection coating the entire top surface, arrays with a central fibronectin pattern increased the percentage of cells localized to the pallet center by 3-4 fold. Localization of cells to the pallet center also enabled the physical separation of cells from optical artifacts created by the rough pallet side walls. To demonstrate the measurement of dynamic intracellular signaling on the arrays, fluorescence measurements of high spatial resolution were performed using a RhoA GTPase biosensor. This biosensor utilized fluorescence resonance energy transfer (FRET) between cyan fluorescent protein (CFP) and yellow fluorescent protein (YFP) to measure localized RhoA activity in cellular ruffles at the cell periphery. These results demonstrated the ability to perform spatially resolved measurements of fluorescence-based sensors on the pallet arrays. Thus, the patterned pallet arrays should enable novel cell separations in which cell selection is based on complex cellular signaling properties.

Automatic design of 3-d fixtures and assembly pallets  

SciTech Connect

This paper presents an implemented algorithm that automatically designs fixtures and assembly pallets to hold three-dimensional parts. The designed fixtures rigidly constrain and locate the part, obey task constraints, are robust to part shape variations, are easy to load, and are economical to produce. The algorithm is guaranteed to find the global optimum solution that satisfies these and other pragmatic conditions. We present the results of the algorithm applied to several practical manufacturing problems. For these complex problems the algorithm typically returns initial high-quality fixture designs in less than two minutes, and identifies th global optimum design in just over an hour.

Automatic design of 3-D fixtures and assembly pallets  

SciTech Connect

This paper presents an implemented algorithm that automatically designs fixtures and assembly pallets to hold three-dimensional parts. All fixtures generated by the algorithm employ round side locators, a side clamp, and cylindrical supports; depending on the value of an input-control flag, the fixture may also include swing-arm top clamps. Using these modular elements, the algorithm designs fixtures that rigidly constrain and locate a part, obey task constraints, are robust to part-shape variations, are easy to load, and are economical to produce. For the class of fixtures that are considered, the algorithm is guaranteed to find the global optimum design that satisfies these and other pragmatic conditions. The authors present the results of the algorithm applied to several practical manufacturing problems. For these complex problems, the algorithm typically returns initial high-quality fixture designs in less than a minute, and identifies the global optimum design in just over an hour. The algorithm is also capable of solving difficult design problems where a single fixture is desired that can hold either of two parts.

Computer simulation of rocket/missile safing and arming mechanism (containing pin pallet runaway escapement, three-pass involute gear train and acceleration driven rotor)  

NASA Astrophysics Data System (ADS)

A complete simulation of missile and rocket safing and arming (S&A) mechanisms containing an acceleration-driven rotor, a three-pass involute gear train, and a pin pallet runaway escapement was developed. In addition, a modification to this simulation was formulated for the special case of the PATRIOT M143 S&A mechanism which has a pair of driving gears in addition to the three-pass gear train. The three motion regimes involved in escapement operation - coupled motion, free motion, and impact - are considered in the computer simulation. The simulation determines both the arming time of the device and the non-impact contact forces of all interacting components. The program permits parametric studies to be made, and is capable of analyzing pallets with arbitrarily located centers of mass. A sample simulation of the PATRIOT M143 S&A in an 11.9 g constant acceleration arming test was run. The results were in good agreement with laboratory test data.

Contact dynamics testing of automated three-point docking mechanism  

NASA Astrophysics Data System (ADS)

An evaluation of an OMV docking mechanism, based on an adaptation of the Shuttle Flight Support System Pallet Berthing Mechanism was completed. The mechanism uses automatically actuated motorized latches to engage towel bars on the target satellite. LED sensors establish the towel bar position within the capture envelope and the latch capture commands are issued. Then, locking pawls engage the bar, locking and pre-loading the mechanism. Two series of tests were conducted to test nominal and failure mode captures and to evaluate design parameters such as LED sensor locations, automatic closure algorithms, latch closure velocity, position/velocity entry envelopes, and closure method. The first test series involved single latch testing on the Flat Floor Facility, the 6 DOF Facility, and an analytic simulation model. The intent was to compare results in order to validate the various facilities. Reasonably good agreement was achieved. The second test series repeated the single latch testing on the refurbished 6 DOF Facility to validate the facility modifications. The individual latches were tested under free-drift conditions for functionality and performance. Next, the three-latch configuration underwent parametric testing. Test results validated the improved fidelity of the 6 DOF Facility and verified successful docking at the required entry velocity. The tests determined the 'best' design parameter definitions and concluded that the locking pawls should not lock until all three latches completely close.

The Federal Facility Agreement and Consent Order was entered into by the State of Nevada, U.S. Department of Energy, and U.S. Department of Defense to identify sites of potential historical contamination and implement corrective actions based on public health and environmental considerations. The facilities subject to this agreement include the Nevada Test Site (NTS), parts of the Tonopah Test Range, parts of the Nellis Air Force Range, the Central Nevada Test Area, and the Project Shoal Area. Corrective Action Sites (CASs) are areas potentially requiring corrective actions and may include solid waste management units, individual disposal, or release sites. Based on geography, technical similarity, agency responsibility, or other appropriate reasons, CASs are grouped together into Corrective Action Units (CAUs) for the purposes of determining corrective actions. This report contains the Closure Verification Forms for cleanup activities that were performed at 13 CASs within CAU 463 on the NTS. The Housekeeping Closure Verification Form for each CAS provides the location, directions to the site, general description, and photographs of the site before and after cleanup activities. Housekeeping activities at these sites included removal of debris (e.g., wooden pallets, metal, glass, and trash) and other material. In addition, these forms confirm prior removal of other contaminated materials such as metal drums or buckets, transformers, lead bricks, batteries, and gas cylinders. Based on these activities, no further action is required at these CASs.

Subsections IWP and IWV of Section XI of the Code state test method and frequency requirements for pumps and valves respectively. Tests vary greatly in quality and frequency. This paper explores the concept of test quality and its relationship with operational readiness and preventive maintenance. This paper also considers the frequencies of component testing. Test quality is related to a test`s ability to detect degradation that can cause component failure. The quality of the test depends on several factors, including specific parameters measured, system or component conditions, and instrument accuracy. The quality of some currently required tests for check valves, motor-operated valves, and pumps is also discussed. Suggestions are made to improve test quality by measuring different parameters, testing valves under load, and testing positive displacement pumps at high pressure and centrifugal pumps at high flow rate conditions. These suggestions can help to improve the level of assurance of component operational readiness gained from testing.

Star calibration of the pallet inertial sensor assembly for the high-altitude balloon experiment  

NASA Astrophysics Data System (ADS)

A gyroscope star calibration algorithm developed for use in the High- Altitude Balloon Experiment, a program to resolve acquisition, tracking, and pointing/fire control issues in support of future directed energy programs, is presented. The initial acquisition of a target from a free- floating balloon platform necessitates an inertial pointing capability. Gyroscopes are normally used to measure angular rotations with respect to an inertial reference frame. Given an initial attitude, the gyro measurements can be used to determine the attitude at any later time. For the High Altitude Balloon Experiment, GPS and a magnetometer are used to provide an initial estimate of the payload attitude. This paper describes a deterministic algorithm, which uses star sensors measurements to correct initial attitude uncertainty errors. In addition, a simple method for measuring gyro bias in flight is presented. The consequences of star sensor to gyro frame misalignment are examined for both rate gyros and angular pulse output gyros. This paper describes the algorithm used to meet the calibration accuracy required to inertial pointing of the gimbaled payload.

Results from the CDX-U Lithium Wall and NSTX Lithium Pallet Injection and Evaporation Experiments  

SciTech Connect

CDX-U has been operated with the vacuum vessel wall and limiter surfaces nearly completely coated with lithium, producing dramatic improvements to plasma performance. Discharges achieved global energy confinement times up to 6 ms, exceeding previous CDX-U results by a factor of 5, and ITER98P(y,1) scaling by 2-3. Lithium wall coatings up to 1000 {angstrom} thick were applied between discharges by electron-beam-induced evaporation of a lithium-filled limiter and vapor deposition from a resistively heated oven. The e-beam power was modest (1.6 kW) but it produced up to 60 MW/m2 power density in a 0.3 cm{sup 2} spot; the duration was up to 300 s. Convective transport of heat away from the beam spot was so effective that the entire lithium inventory (140 g) was heated to evaporation (400-500 C) and there was no observable hot spot on the lithium surface within the beam footprint. These results are promising for use of lithium plasma-facing components in reactor scale devices. Lithium coating has also been applied to NSTX carbon plasma-facing surfaces, to control the density rise during long-duration H-modes for non-inductive current sustainment. First, lithium pellets were injected into sequences of Ohmically heated helium plasmas in both center stack limiter (CSL) and lower single-null divertor (LSND) configurations to deposit a total of 25-30 mg of lithium on the respective plasma contact areas. In both cases, the first subsequent L mode, deuterium discharge with NBI showed a reduction in the volume-average density by a factor {approx}3 compared to similar discharges before the lithium coating. Recently, a lithium evaporator was installed aimed toward the graphite tiles of the lower center stack and divertor. Twelve depositions, ranging from about 10 mg to 5 g of lithium, were performed. The effects on LSND L-mode, double-null divertor (DND) H-mode, and DND reversed-shear plasmas were variable but, immediately after coating, there were decreases in the density and significant increases in electron and ion temperature, neutron rate, confinement time, and edge flow velocity, and reductions in H-mode ELM frequency. For several days of operation after lithium coating, the ratio of oxygen to carbon emission was lower than with boronization.

This crushing test is also a good example of how a particular test does not always give enough information to answer a question. This is a follow-up to the activity called "Curious Crystals," in which learners investigate crystals and their properties to identify an unknown crystal.

Performance tests.  

PubMed Central

This paper discusses the use of psychological performance tests to assess the effects of environmental stressors. The large number and the variety of performance tests are illustrated, and the differences between performance tests and other psychological tests are described in terms of their design, construction, use, and purpose. The stressor emphasis is on the effects of drugs since that is where most performance tests have found their main application, although other stressors, e.g., fatigue, toxic chemicals, are mentioned where appropriate. Diazepam is used as an example. There is no particular performance emphasis since the tests are intended to have wide applicability. However, vehicle-driving performance is discussed because it has been the subject of a great deal of research and is probably one of the most important areas of application. Performance tests are discussed in terms of the four main underlying models--factor analysis, general information processing, multiple resource and strategy models, and processing-stage models--and in terms of their psychometric properties--sensitivity, reliability, and content, criterion, construct, and face validity. Some test taxonomies are presented. Standardization is also discussed with reference to the reaction time, mathematical processing, memory search, spatial processing, unstable tracking, verbal processing, and dual task tests used in the AGARD STRES battery. Some comments on measurement strengths and appropriate study designs and methods are included.

Epicutaneous testing.  

PubMed

The patch test and chamber test are the ordinary methods for detecting delayed type contact allergies. The method, test substances and criteria of positive reactions are already well standardized. Open testing is also used for problematic chemicals such as strong topical medicaments, emulsifiers and propylene glycol. The many problems of standardization are still unresolved in photocutaneous testing. Some chemicals are applied to the skin without occlusion, though the chamber test or patch test methods are used with most of them. The composition of the vehicle and occlusion time vary greatly from one photosensitizing substance to another. A xenon arc is recommended for screening any photosensitizers but fluorescent black light tubes are sufficient for routine clinical use. Type I contact allergies are far more common than was previously believed, especially among people allergic to birch pollen. This type of reaction and other forms of contact urticaria can be examined using the scratch chamber or scarification chamber techniques as well as with an open test on diseased or scratched (scarified) skin.

Test tree  

SciTech Connect

A subsurface test tree so compact in its vertical dimension that the entire tree can be positioned below the blind rams in a blowout preventer stack. When the stinger is removed the remaining valve section of the tree will be below the blind rams in any conventional blowout preventer stack. The valve operators are split, one carried by the stinger and one carried in the valve housing with the arrangement of operator and valve in the housing providing an extremely small vertical dimension. A dome charge is effective on a piston to drive a ball valve to closed position to cut a line extending through the ball valve and to provide sequential operation between the ball valve on bottom and the valve thereabove which may be a flapper valve so that the lower valve closes and the line is cut before the upper valve closes. In one form the invention includes a subsurface safety valve below the test tree operated by one of control or balance pressure fluid.

Collaborative Testing  

PubMed Central

Purpose: With increased focus on student preparation for high-stakes licensure exams, there is more interest in alternate forms of content delivery and assessment. This interest has focused on factors within the learning environment that may impact student's course performance and program progress. In this project, the impact of the method of group determination (random assignment vs. student selection) on student performance in a neuroanatomy course within a collaborative testing environment is examined. Methods: The course performance of two cohorts (cohort one: randomized grouping = 80; cohort two: student-selected grouping = 82) were compared. All students completed weekly quizzes within collaborative groups, while completing unit exams individually. The mean sum of both the quiz scores and examination scores were compared. Results: While the two groups differed (Wilks' lambda = 0.211; F = 53.541; df = 10,143; p < .05), no pattern was evident among the assessments (ie, one group did not differ significantly on all quizzes or examinations). In overall quiz performance, the randomized groupings scored significantly higher than the student-selected groups (F = 112.252; df = 1152; p < .05) while no difference was noted relative to overall exam scores (F = 2.672; df = 1152; p > .05). Conclusions: While the collaborative testing paradigm has been shown to be a valuable learning tool, no differences are apparent in the course performance between students in randomly assigned groups compared to those in student-selected groups. The very nature of random groups may have encouraged students to be proficient in all of the material, whereas students who were allowed to choose their groups may have divided the material among themselves and not become individually proficient in all concepts.

APU diaphragm testing. Test plan  

NASA Astrophysics Data System (ADS)

Auxiliary Power Unit (APU) fuel (hydrazine) tanks have had to be removed from the Columbia Shuttle (OV-102) because they have been in service for 11 years, which is the limit of their useful life. As part of an effort to determine whether the useful life of the fuel tanks can be extended, examination of the ethylene propylene rubber (EPR) diaphragm and the metal from one of the APU tanks is required. The JSC Propulsion and Power Division has requested White Sands Test Facility (WSTF) to examine the EPR diaphragm thoroughly and the metal casing generally from one tank. The objective is to examine the EPR diaphragm for signs of degradation that may limit the life of its function in the APU propellant tank. The metal casing will also be examined for signs of surface corrosion.

Vendor System Vulnerability Testing Test Plan  

SciTech Connect

The Idaho National Laboratory (INL) prepared this generic test plan to provide clients (vendors, end users, program sponsors, etc.) with a sense of the scope and depth of vulnerability testing performed at the INL’s Supervisory Control and Data Acquisition (SCADA) Test Bed and to serve as an example of such a plan. Although this test plan specifically addresses vulnerability testing of systems applied to the energy sector (electric/power transmission and distribution and oil and gas systems), it is generic enough to be applied to control systems used in other critical infrastructures such as the transportation sector, water/waste water sector, or hazardous chemical production facilities. The SCADA Test Bed is established at the INL as a testing environment to evaluate the security vulnerabilities of SCADA systems, energy management systems (EMS), and distributed control systems. It now supports multiple programs sponsored by the U.S. Department of Energy, the U.S. Department of Homeland Security, other government agencies, and private sector clients. This particular test plan applies to testing conducted on a SCADA/EMS provided by a vendor. Before performing detailed vulnerability testing of a SCADA/EMS, an as delivered baseline examination of the system is conducted, to establish a starting point for all-subsequent testing. The series of baseline tests document factory delivered defaults, system configuration, and potential configuration changes to aid in the development of a security plan for in depth vulnerability testing. The baseline test document is provided to the System Provider,a who evaluates the baseline report and provides recommendations to the system configuration to enhance the security profile of the baseline system. Vulnerability testing is then conducted at the SCADA Test Bed, which provides an in-depth security analysis of the Vendor’s system.b a. The term System Provider replaces the name of the company/organization providing the system being evaluated. This can be the system manufacturer, a system user, or a third party organization such as a government agency. b. The term Vendor (or Vendor’s) System replaces the name of the specific SCADA/EMS being tested.

Does It Work? Test and Test Again  

NSDL National Science Digital Library

Testing is critical to any design, whether it be in the creation of new software or building a bridge across a wide river. Despite risking the quality of the design, the testing stage is often hurried in order to get products to market. In this lesson, students focus on the testing phase of the software/systems design process. They start by exploring existing examples of program testing using the CodingBat website, which contains a series of problems and challenges that students solve using the Java programming language. Working in teams, students practice writing test cases for other groups' code, and then write test cases for a program before writing the program itself.

Test procedure for prism compression testing  

SciTech Connect

This procedure describes the setup and procedure for testing hollow clay tile (HCT) masonry prisms. The prism test is the standard engineering test used to determine values for f`{sub m} (specified compressive strength at 28 days) which are then used to obtain Code design allowable values. The prism compression test described herein produces load vs. deflection data which can be used to determine various properties such as the compressive strength, Modulus of Elasticity, and Poisson`s ratio. The test prisms are obtained either by extraction from an existing wall or by fabrication using new materials. Prisms obtained from existing walls are fragile and tedious to extract and handle, but are very important because they provide data on the properties of existing walls. Laboratory-built prisms, used to supplement the in-situ prism test data, are easier to obtain, and allow for better control of the prism. Tests are to be made on prism specimens in two directions with respect to the cores: normal and parallel to the cores. Typically, in the Y-12 Plant buildings that have the HCT infill walls, the walls are constructed such that the cores in the HCT units run horizontally. Loading normal to the cores simulates vertical loading (gravity and vertical earthquake motions) on the walls, and loading parallel to the cores simulates the earthquake forces applied to a building wall in the horizontal direction. Prisms of single wythe 8-in. walls and the composite wythe 13-in. walls will be tested. A special Test Fixture (frame) has been designed and built to perform the in-house testing of prisms. Special handling fixtures have been designed to protect the prisms during removal from the wall site and transportation to the Test Fixture. The Test Fixture was designed for approximately a 400 kip allowable load limit.

The options available in the area of small-scale flight testing are examined, and the relationship between the results obtained by flight testing, ground testing, and simulation is discussed. Attention is given to instrumentation currently available for flight testing, and it is shown how flight tests can be used to validate or improve models. Some results are presented to indicate areas where ground testing and modeling alone are not sufficient for the accurate prediction of aerodynamics and aerothermodynamics in the hypersonic environment.

Constructing objective tests  

NSDL National Science Digital Library

Trueâfalse or multiple-choice tests can be useful instruments for evaluating student progress. We examine strategies for planning objective tests which serve to test the material covered in science (physics) courses. We also examine strategies for writing questions for tests within a test blueprint. The statistical basis for judging the quality of test items are discussed. Reliability, difficulty, and discrimination indices are defined and examples presented. Our recommendations are rather easily put into practice.

Test of integrity.  

PubMed

HIV drug resistance is a major concern, and Specialty Laboratories has developed a new high-tech test that may help physicians identify and manage resistance. Their genetic-testing service claims to detect HIV mutations in blood, but many say the test is ineffective and costly. The manufacturer hopes the test reports will allow doctors to avoid prescribing drugs that will not work, and claim that the test can be a good tool when used with physical exams and other tests. Critics claim that physicians will misinterpret test data. The company is currently selling 2,000 tests each month, at $400 each. PMID:11364639

Standard anaerobic exercise tests.  

PubMed

Anaerobic tests are divided into tests measuring anaerobic power and anaerobic capacity. Anaerobic power tests include force-velocity tests, vertical jump tests, staircase tests, and cycle ergometer tests. The values of maximal anaerobic power obtained with these different protocols are different but generally well correlated. Differences between tests include factors such as whether average power or instantaneous power is measured, active muscle mass is the same in all the protocols, the legs act simultaneously or successively, maximal power is measured at the very beginning of exercise or after several seconds, inertia of the devices and body segments are taken into account. Force-velocity tests have the advantage of enabling the estimation of the force and velocity components of power, which is not possible with tests such as a staircase test, a vertical jump, the Wingate test and other long-duration cycle ergometer protocols. Maximal anaerobic capacity tests are subdivided into maximal oxygen debt test, ergometric tests (all-out tests and constant load tests), measurement of oxygen deficit during a constant load test and measurement of peak blood lactate. The measurement of the maximal oxygen debt is not valid and reliable enough to be used as an anaerobic capacity test. The aerobic metabolism involvement during anaerobic capacity tests, and the ignorance of the mechanical efficiency, limit the validity of the ergometric tests which are only based on the measurement of work. The amount of work performed during the Wingate test depends probably on glycolytic and aerobic power as well as anaerobic capacity. The fatigue index (power decrease) of the all-out tests is not reliable and depends probably on aerobic power as well as the fast-twich fibre percentage. Reliability of the constant load tests has seldom been studied and has been found to be rather low. In theory, the measure of the oxygen deficit during a constant load test is more valid than the other tests but its reliability is unknown. The validity and reliability of postexercise blood lactate as a test of maximal anaerobic capacity are probably not better than that of the current erogmetric tests. The choice of an anaerobic test depends on the aims and subjects of a study and its practicability within a testing session. PMID:3306867

Test the Nation: The National IQ Test  

NSDL National Science Digital Library

Who is the weakest link? Or, rather, just how many are there? And where do they come from? Test the Nation, Britain's largest mass IQ test set about to answer those questions and more on May 11th of this year. Administered online to some 90,000 residents of the UK (and still available for those who missed out), the test put visitors through the usual rigors of intelligence testing. The Test the Nation Web site discloses how the nation did as a whole, with further breakdowns by region, age, and other variables. Curious, the map of Britain's intelligence, as determined by the test, clearly demonstrates that the South far outdid the North where brute IQ is concerned. Whether one accepts such results or not, the site provides much food for thought, discussion and, almost certainly, an argument or two. Presented by the BBC, the site doesn't stop with simple presentations on the national IQ test, but also offers other interesting studies and reports, with subjects probing various areas of intelligence testing and all that has been made of it. A short list of some of the titles presented include: What sex is your brain?, Birth weight and intelligence, and The Language of the brain. To round off it offerings, the site also links to MENSA.

PACS component testing: beta and acceptance testing  

NASA Astrophysics Data System (ADS)

The functionality and performance expectations of all PACS components must be specified at the time of purchase and tested completely upon delivery to assure customer satisfaction and successful adoption of the new technology. This process may be more elaborate if the customer agrees to serve as a Beta test site for a new component or a new revision of an existing component.A carefully designed test plan will save time at installation, will allow the customer and vendor to agree on expectations, and will assure that the installation will proceed as planned. This paper describes the test procedure used at the University of Florida to accept each PACS component, either a commercial product, or one developed in house. A set of documents contain descriptions of the pre-installation environment, sets of studies to be used in the test, installation checklist, functional usage reports, subjective evaluations, and problem reporting forms. Training and user documentation is also reviewed and 'help lists' are created to help users perform the most common functions. Although details in the documents are changed to match the type of component being tested, the general form of the test remains the same. A formal procedure for testing the functionality and performance of new equipment can save time for both the vendor and the customer and, if specified at the time of purchase, can serve to document the expectations of the customer. Following these procedures will assure a successful installation and improve customer satisfaction.

Test report for core drilling ignitability testing  

SciTech Connect

Testing was carried out with the cooperation of Westinghouse Hanford Company and the United States Bureau of Mines at the Pittsburgh Research Center in Pennsylvania under the Memorandum of Agreement 14- 09-0050-3666. Several core drilling equipment items, specifically those which can come in contact with flammable gasses while drilling into some waste tanks, were tested under conditions similar to actual field sampling conditions. Rotary drilling against steel and rock as well as drop testing of several different pieces of equipment in a flammable gas environment were the specific items addressed. The test items completed either caused no ignition of the gas mixture, or, after having hardware changes or drilling parameters modified, produced no ignition in repeat testing.

Role of test motivation in intelligence testing  

PubMed Central

Intelligence tests are widely assumed to measure maximal intellectual performance, and predictive associations between intelligence quotient (IQ) scores and later-life outcomes are typically interpreted as unbiased estimates of the effect of intellectual ability on academic, professional, and social life outcomes. The current investigation critically examines these assumptions and finds evidence against both. First, we examined whether motivation is less than maximal on intelligence tests administered in the context of low-stakes research situations. Specifically, we completed a meta-analysis of random-assignment experiments testing the effects of material incentives on intelligence-test performance on a collective 2,008 participants. Incentives increased IQ scores by an average of 0.64 SD, with larger effects for individuals with lower baseline IQ scores. Second, we tested whether individual differences in motivation during IQ testing can spuriously inflate the predictive validity of intelligence for life outcomes. Trained observers rated test motivation among 251 adolescent boys completing intelligence tests using a 15-min “thin-slice” video sample. IQ score predicted life outcomes, including academic performance in adolescence and criminal convictions, employment, and years of education in early adulthood. After adjusting for the influence of test motivation, however, the predictive validity of intelligence for life outcomes was significantly diminished, particularly for nonacademic outcomes. Collectively, our findings suggest that, under low-stakes research conditions, some individuals try harder than others, and, in this context, test motivation can act as a third-variable confound that inflates estimates of the predictive validity of intelligence for life outcomes.

Entry/Exit Port testing, test report  

SciTech Connect

The Waste Receiving and Processing Module I (WRAP-1) facility must have the ability to allow 55-gallon drums to enter and exit glovebox enclosures. An Entry/Exit Port (Appendix 1, Figure 1), designed by United Engineers and Constructors (UE&C), is one method chosen for drum transfer. The Entry/Exit Port is to be used for entry of 55-gallon drums into both process entry gloveboxes, exit of 55-gallon drum waste pucks from the low-level waste (LLW) glovebox, and loadout of waste from the restricted waste management glovebox. The Entry/Exit Port relies on capture velocity air flow and a neoprene seal to provide alpha confinement when the Port is in the open and closed positions, respectively. Since the glovebox is in a slight vacuum, air flow is directed into the glovebox through the space between the overpack drum and glovebox floor. The air flow is to direct any airborne contamination into the glovebox. A neoprene seal is used to seal the Port door to the glovebox floor, thus maintaining confinement in the closed position. Entry/Exit Port testing took place February 17, 1993, through April 14, 1993, in the 305 building of Westinghouse Hanford Company. Testing was performed in accordance with the Entry/Exit Port Testing Test Plan, document number WHC-SD-WO26-TP-005. A prototype Entry/Exit Port built at the Hanford Site was tested using fluorescent paint pigment and smoke candles as simulant contaminants. This test report is an interim test report. Further developmental testing is required to test modifications made to the Port as the original design of the Port did not provide complete confinement during all stages of operation.

Tests of Halon 1301 test gas simulants  

NASA Astrophysics Data System (ADS)

All new and retrofit installations of Halon 1301 (CBrF3) total flooding fire protection systems in shipboard machinery spaces require full acceptance discharge test. It is desirable to use a suitable simulant test gas in these tests in view of current and future regulation of Halon 1301. Sulfur hexafluoride, SF6, and chlorodifluromethane R-22, were identified as candidate simulants on the basis of their similarity in physical properties to Halon 1301. These two candidates were then evaluated on the basis of leakage from an enclosure. SF6 was determined to be an excellent simulant for Halon 1301 when considering leakage from an enclosure. Further testing of SF6 and R-22 is planned for other important aspects of Halon 1301 systems, i.e., flow hydraulics, initial mixing.

A Sensor Test Facility (STF) was recently established at the Department of Energy`s Nevada Test Site (NTS). It has been used for a series of sensor tests that have demonstrated the usefulness of the testbed. The facility consists of a cut-and-cover bunker complex and the two square mile surrounding area. The STF was developed as a scientific testbed optimized for the development and evaluation of advanced sensor systems, including ground sensor systems designed to identify and detect hardened underground facilities. This was accomplished by identifying a facility in a remote location where seismic, acoustic, and electromagnetic interference would be minimal, establishing a testbed that would be accommodating to field testing, and conducting a thorough geophysical characterization of the area surrounding the facility in order to understand the local geology and its effects on geophysical signals emanating from the facility. The STF is representative of a number of cut-and-cover bunkers around the world that are used for the manufacture and/or storage of weapons of mass destruction. This paper provides a general description of the Nevada Test Site, the Sensor Test Facility, and the Geophysical Site Characterization.

ECN Pressure Test  

SciTech Connect

This note describes: the rationale for the test pressure of the inner ECN cryostat vessel, the equipment to be used in this test, the test procedure, the status of the vessel prior to the test, the actual test results, and a schematic diagram of the testing set up and the pressure testing permit. The test, performed in the evening of July 17, 1991, was a major success. Based on a neglible pressure drop indicated on the pressure gages (1/4 psi), the vessel appeared to be structurally sound throughout the duration of the test (approx. 1.5 hrs.). No pressure increases were observed on the indicators looking at the beam tube bellows volumes. There was no indication of bubbles form the soap test on the welds and most of the fittings that were checked. There were some slight deviations in the actual procedure used. The UO filter was removed after the vessel had bled down to about 18 psig in order to speed up that aspect of the test. The rationale was that the higher velocity gas had already passed through at the higher pressures and there was no visible traces of the black uo particles. The rate of 4 psi/10 minutes seemed incredibly slow and often that time was reduced to just over half that rate. The testing personnel was allowed to stay in the pit throughout the duration of the test; this was a slight relaxation of the rules.

Smart HIV testing system.  

PubMed

The quick HIV testing method called "MiraWell Rapid HIV Test" uses a specialized testing kit to determine whether an individual's blood is contaminated with the HIV virus or not. When a drop of blood is placed on the center of the testing kit, a simple pattern will appear in the middle of the kit to indicate the test status, i.e., positive or negative. This HIV test should be done in a small clinic or in a lab and the test must be conducted by a trained technician. A smart HIV testing system was developed through this research to eliminate the human error that is associated with the use of the quick HIV testing kits. Also, the smart HIV system will improve the testing productivity in comparison to those achieved by the trained technicians. In this research, we have developed a cost-effective system that analyzes the image produced by the HIV kits. We have used a System-On-Chip (SOC) design approach based on the Field Programmable Gate Array (FPGA) technology and the Xilinx Virtex SOC chip in building the system's prototype. The system used a CMOS digital camera to capture the image and an FPGA chip to process the captured image and send the testing results to the display unit. The system can be used in small clinics and pharmacies and eliminates the need for trained technicians. The system has been tested successfully and 98% of the tests were correct. PMID:16078623

This invention pertains to arrangements for performing electrical tests on contact material samples, and in particular for testing contact material test samples in an evacuated environment under high current loads. Frequently, it is desirable in developing high-current separable contact material, to have at least a preliminary analysis of selected candidate conductor materials. Testing of material samples will hopefully identify materials unsuitable for high current electrical contact without requiring incorporation of the materials into a completed and oftentimes complex structure.

Flight Testing and Test Instrumentation of PHOENIX  

NASA Astrophysics Data System (ADS)

Within the frame of the German national ASTRA program, the need for in-flight experimentation as a key element in the development of the next generation launcher was addressed by the Phoenix project. The Phoenix 1 flight test vehicle was designed to demonstrate the un-powered horizontal landing of a representative, winged RLV configuration. The Phoenix 1 flight test vehicle is downscaled from the reference RLV shape "Hopper", with the dimensions of 7.8m overall length, 3.8m span, and 1200kg mass. In order to be representative of a full scale RLV, the scaling method preserves all features challenging the automatic landing from the flight control point of view. These are in particular the poor flying qualities of the static unstable vehicle and the high landing velocity of 71m/s, which is same as for the full scale vehicle. The landing demonstration scenario comprises a drop from the helicopter approximately 6km ahead of the runway threshold at 2.4km above runway level. The subsequent free flight includes an accelerating dive to merge with a steep final approach path representative of an RLV, followed by a long flare, touch down on the runway, and rollout to standstill. Besides its mandatory avionics system, the vehicle is also equipped with an additional flight test instrumentation to identify local aerodynamic flow and structural stress. This FTI system is designed to collect data by recording about 130 sensor signals during flight. This test instrumentation system was operated during a test campaign dedicated to verify the aerodynamic data base of Phoenix in the Dutch-German Wind-tunnel (DNW) in August 2003 and during three automatic landing flight tests after helicopter drop in May 2004. Post flight analysis of these data allows to validate the design models and the development tools in order to establish a flight validated data base for future work. This paper gives an overview on the Phoenix system including the flight test instrumentation, the test program and the results and lessons learned from the different campaigns.

Fitness Testing Athletes  

PubMed Central

Fitness testing of athletes can be subdivided into tests of body build, strength, aerobic power, and tests specific to the athletic event. World class athletes seem to fall into specific body types for the individual events. The top athlete usually has very little of the endomorphic characteristics and should be lean. Strength testing should be used more frequently as weight and isometric training techniques are used by many athletes and coaches without specific goals. The aerobic power of many national class athletes may be only 10-30 percent above that of the general population, and high values were found only in cyclists and distance runners. It is emphasized that the scores of fitness tests are specific for each test and do not necessarily correlate at all with athletic performance which is also specific. Despite this limitation, fitness tests do have a place in athletics and should be utilized more fully and with more understanding by coaches and athletes. Imagesp48-a

[The Doppler palm test].  

PubMed

In 384 hands the patency of the arterial arch was investigated by means of both the Allen test and the Doppler palmar arch test as developed by the authors. While the Allen test is purely subjective and gives a high proportion of false results especially in shocked patients, the Doppler palmar arch test is based on two objective criteria: 1. Demonstration of reversed flow in the distal section of the radial artery on proximal compression. 2. Demonstration of pulsatile flow in the radial thumb artery even on compression of the radial artery. The Doppler palmar arch test eliminates all negative aspects of the Allen test and is therefore definitely more reliable than the latter. It is easy to perform for investigators having little experience with Doppler sonography. The time consumed is not greater than with the Allen test. PMID:3041584

Sample Proficiency Test exercise  

SciTech Connect

The current format of the OPCW proficiency tests has multiple sets of 2 samples sent to an analysis laboratory. In each sample set, one is identified as a sample, the other as a blank. This method of conducting proficiency tests differs from how an OPCW designated laboratory would receive authentic samples (a set of three containers, each not identified, consisting of the authentic sample, a control sample, and a blank sample). This exercise was designed to test the reporting if the proficiency tests were to be conducted. As such, this is not an official OPCW proficiency test, and the attached report is one method by which LLNL might report their analyses under a more realistic testing scheme. Therefore, the title on the report ''Report of the Umpteenth Official OPCW Proficiency Test'' is meaningless, and provides a bit of whimsy for the analyses and readers of the report.

COLD TEST LOOP INTEGRATED TEST LOOP RESULTS  

SciTech Connect

A testing facility (Cold Test Loop) was constructed and operated to demonstrate the efficacy of the Accelerated Waste Retrieval (AWR) Project's planned sluicing approach to the remediation of Silos 1 and 2 at the Fernald Environmental Management Project near Cincinnati, Ohio. The two silos contain almost 10,000 tons of radium-bearing low-level waste, which consists primarily of solids of raffinates from processing performed on ores from the Democratic Republic of Congo (commonly referred to as ''Belgium Congo ores'') for the recovery of uranium. These silos are 80 ft in diameter, 36 ft high to the center of the dome, and 26.75 ft to the top of the vertical side walls. The test facility contained two test systems, each designed for a specific purpose. The first system, the Integrated Test Loop (ITL), a near-full-scale plant including the actual equipment to be installed at the Fernald Site, was designed to demonstrate the sluicing operation and confirm the selection of a slurry pump, the optimal sluicing nozzle operation, and the preliminary design material balance. The second system, the Component Test Loop (CTL), was designed to evaluate many of the key individual components of the waste retrieval system over an extended run. The major results of the initial testing performed during July and August 2002 confirmed that the AWR approach to sluicing was feasible. The ITL testing confirmed the following: (1) The selected slurry pump (Hazleton 3-20 type SHW) performed well and is suitable for AWR application. However, the pump's motor should be upgraded to a 200-hp model and be driven by a 150-hp variable-frequency drive (VFD). A 200-hp VFD is not much more expensive and would allow the pump to operate at full speed. (2) The best nozzle performance was achieved by using 15/16-in. nozzles operated alternately. This configuration appeared to most effectively mine the surrogate. (3) The Solartron densitometer, which was tested as an alternative mass flow measurement device, did not operate effectively. Consequently, it is not suitable for application to the AWR process. (4) Initially, the spray ring (operated at approximately 2300 psi) and the nozzles provided by the pump vendor did not perform acceptably. The nozzles were replaced with a more robust model, and the performance was then acceptable. (5) The average solids concentration achieved in the slurry before Bentogrout addition was approximately 16% by weight. The solids concentration of the slurry after Bentogrout addition ranged from 26% to approximately 40%. The slurry pump and ITL system performed well at every concentration. No line plugging or other problems were noted. The results of the CTL runs and later ITL testing are summarized in an appendix to this report.

The Department of Energy’s Advanced Vehicle Testing Activity (AVTA) is testing advanced technology vehicles to help reduce this dependency, which would contribute to the economic stability and homeland security of the United States. These advanced technology test vehicles include internal combustion engine vehicles operating on 100% hydrogen (H2) and H2CNG (compressed natural gas) blended fuels, hybrid electric vehicles, neighborhood electric vehicles, urban electric vehicles, and electric ground support vehicles. The AVTA tests and evaluates these vehicles with closed track and dynamometer testing methods (baseline performance testing) and accelerated reliability testing methods (accumulating lifecycle vehicle miles and operational knowledge within 1 to 1.5 years), and in normal fleet environments. The Arizona Public Service Alternative Fuel Pilot Plant and H2-fueled vehicles are demonstrating the feasibility of using H2 as a transportation fuel. Hybrid, neighborhood, and urban electric test vehicles are demonstrating successful applications of electric drive vehicles in various fleet missions. The AVTA is also developing electric ground support equipment (GSE) test procedures, and GSE testing will start during the fall of 2003. All of these activities are intended to support U.S. energy independence. The Idaho National Engineering and Environmental Laboratory manages these activities for the AVTA.

After an empty pressure vessel (shipping container) is assembled, it is placed into one of six stainless steel belljars for helium leak testing. The belljars are fashioned in row much the same as assembly line arrangement. Post-load Test: A post-load leak test is performed upon reservoirs that have been filled with tritium and placed inside the shipping containers mentioned above. These leak tests are performed by a rate-of-rise method where the area around the shipping container seals is evacuated, valved off from the vacuum pump, and then the vacuum pressure is monitored over a two-minute period. The Post Load Leak Test is a quality verification test to ensure that the shipping container has been correctly assembled. 2 figs.

Standardizing boom test procedures  

SciTech Connect

The OHMSETT Interagency Technical Committee (OTIC) sponsored a combined series of in-tank and open-water tests of five booms that cover a wide range of sizes and design parameters. The tests were conducted at the United States Environmental Protection Agency's OHMSETT facility and in Sandy Hook Bay between November 1983 and May 1984. The in-tank tests measured the oil-holding performance of the boom; the open-water tests demonstrated the wave conformance and survivability. The objective was a correlation between the two sets of data. There were five in-tank tests for each boom using a standardized test matrix for oil-holding ability. Wave conformance and endurance were observed under controlled conditions. The results of this testing compared favorably with past tests performed in the tank. The five booms were deployed in the bay from 14 to 27 days, depending on the weather, and were videotaped to document their approximate sea-state limits. The wave conformance of the 500-ft booms deployed in the bay was similar to the conformance of the 100-ft lengths used in the tank, but lack of conformance was more obvious in the bay tests. The in-tank endurance tests did not correlate as well as expected with the open-water testing. Additional testing to obtain both waveform and boom motion data is scheduled for the fall of 1984. These tests are designed to determine the minimum instrumentation and analysis needed to obtain acceptable measurements of boom response in irregular seas.

Tests, testing, and tested - we need to critically evaluate the meaning of tests in psychiatry  

PubMed Central

This article describes clinical pitfalls in our concepts of what it means for an illness, diagnosis, or evaluation and treatment methods to say that they have been “tested”. This articles begins with the problems encountered in newborn testing for Krabbe Disease of the nervous system in New York State over the last few years as an example of a test that did not live up to its promise to help the society. Next, the article gives 3 examples of testing in psychiatry, 1. Psychological testing to make treatment decisions in children with depression, 2. Patient's and parents who have been told, or believe, that they have Asperger's disorder, and 3. The conclusions made about the efficacy of cognitive behavioral therapy based on clinical studies. The article's conclusion sums up these examples as reasons why we need to have a more practical and scientific approach to our understanding and implementation of tests used in our field.

Advanced Technology Vehicle Testing  

SciTech Connect

The goal of the U.S. Department of Energy's Advanced Vehicle Testing Activity (AVTA) is to increase the body of knowledge as well as the awareness and acceptance of electric drive and other advanced technology vehicles (ATV). The AVTA accomplishes this goal by testing ATVs on test tracks and dynamometers (Baseline Performance testing), as well as in real-world applications (Fleet and Accelerated Reliability testing and public demonstrations). This enables the AVTA to provide Federal and private fleet managers, as well as other potential ATV users, with accurate and unbiased information on vehicle performance and infrastructure needs so they can make informed decisions about acquiring and operating ATVs. The ATVs currently in testing include vehicles that burn gaseous hydrogen (H2) fuel and hydrogen/CNG (H/CNG) blended fuels in internal combustion engines (ICE), and hybrid electric (HEV), urban electric, and neighborhood electric vehicles. The AVTA is part of DOE's FreedomCAR and Vehicle Technologies Program.

Dynamic impact testing with servohydraulic testing machines  

NASA Astrophysics Data System (ADS)

The design concept of “Crashworthiness” requires the information on material behaviour under dynamic impact loading in order to describe and predict the crash behaviour of structures. Especially the transport related industries, like car, railway or aircraft industry, pursue the concept of lightweight design for a while now. The materials' maximum constraint during loading is pushed to permanently increasing figures. This means in terms of crashworthiness that the process of energy absorption in structures and the mechanical behaviour of materials must well understood and can be described appropriately by material models. In close cooperation with experts from various industries and research institutes Instron has developed throughout the past years a new family of servohydraulic testing machines specifically designed to cope with the dynamics of high rate testing. Main development steps are reflected versus their experimental necessities.

Test Particles, Test Modes and Drift Turbulence  

SciTech Connect

Strong electrostatic turbulence in magnetically confined plasmas is characterized by trapping or eddying of test particle trajectories produced by the ExB stochastic drift. Trapping is shown to produce non-standard statistics of trajectories: non-Gaussian distribution, memory effects and quasi-coherence. Two types of effects produced by trapping are analyzed. The first type concerns particle and energy transport and consists in very strong nonlinear modification of the diffusion coefficients. Anomalous diffusion regimes are obtained when the other components of the motion (particle collisions, plasma rotation, the motion along the confining magnetic field) do not destroy trajectory eddying. The second type of effects are evidenced by studying test modes on turbulent plasma. We show that trappyng provides the physical mechanism for the inverse cascade observed in drift turbulence.

Test Results for CSTR Test 4  

SciTech Connect

One of the 3 technologies currently being developed for the Savannah River Salt Waste Processing Program is the Small-Tank Tetraphenylborate Process (STTP). This process uses sodium tetraphenylborate to precipitate and remove radioactive Cs from the waste and monosodium titanate to sorb and remove radioactive Sr and actinides. ORNL is demonstrating this process at the 1:4000 scale using a 20-liter continuous-flow stirred tank reactor (CSTR) system. The primary goal of Test 4 was to verify that the STTP process could achieve and maintain the necessary Cs decontamination while TPB was actively decomposing. Even with TPB being decomposed by the off-normal conditions of this test, the decontaimination factor for {sup 137}Cs obtained for the filtrate from the Slurry Concentrating Tank ranged from 47,000 to 646,000, exceeding the WAC standard.

As capacitor manufacturers race to meet the needs of the hybrid-electric vehicle (HEV) of the future, many trade-offs at the system level as well as the component level must be considered. Even though the ultra-capacitor has the spot light for recent research and development (R&D) for HEVs, the electrostatic capacitor is also the subject of R&D (for HEVs as well as wireless communications). The Department of Energy has funded the Oak Ridge National Laboratory's Power Electronic and Electric Machinery Research Center to develop an automated test to aid in the independent testing of prototype electrostatic capacitors. This paper describes the design and development of such a stand.

Testing of the structural evaluation test unit  

SciTech Connect

In the evaluation of the safety of radioactive material transportation it is important to consider the response of Type B packages to environments more severe than that prescribed by the hypothetical accident sequence in Title 10 Part 71 of the Code of Federal Regulations (NRC 1995). The impact event in this sequence is a 9-meter drop onto an essentially unyielding target, resulting in an impact velocity of 13.4 m/s. The behavior of 9 packages when subjected to impacts more severe than this is not well known. It is the purpose of this program to evaluate the structural response of a test package to these environments. Several types of structural response are considered. Of primary importance is the behavior of the package containment boundary, including the bolted closure and 0-rings. Other areas of concern are loss of shielding capability due to lead slump and the deceleration loading of package contents, that may cause damage to them. This type of information is essential for conducting accurate risk assessments on the transportation of radioactive materials. Currently very conservative estimates of the loss of package protection are used in these assessments. This paper will summarize the results of a regulatory impact test and three extra-regulatory impact tests on a sample package.

Genetic testing of athletes.  

PubMed

This chapter addresses the potential use of genetic tests to predict performance and/or risk of exercise-related injury or illness. Various people may wish to conduct a sport-related genetic test on themselves, or on another person, for a variety of reasons. For example, an individual may seek personal genetic information to assist with choosing their own sporting participation or career. A sports coach may wish to test young team members to assist in selection for a professional career or to individualise training. A physician may want to predict risk of injury or illness in an athlete and advise regarding selection or preventative measures. An insurance company may seek to estimate risk of career-threatening injury or illness to an athlete based partly on genetic information. Despite the commercial availability of some genetic tests today, the evidence currently available suggests that few of these or similar scenarios are scientifically justified - the genetic tests available at the moment are simply not powerful enough to inform important decisions in sport. Furthermore, there are many challenging ethical issues to be addressed regarding genetic testing of athletes. The imposition of genetic tests on individuals by third parties, and particularly the imposition of genetic tests on young people, is potentially susceptible to abuse. There should be considerable further debate regarding these issues so that the tests already available, and the more powerful ones that are likely to emerge as knowledge and genetic technology improve, are only used in acceptable ways.

An outer conductive cylinder is coaxially positioned around the inner cylinder and test specimen to provide a vacuum enclosure therefor. A power source needed to drive test currents through the test specimens is connected to the bottom of each conductive cylinder, through two specially formed conductive plates. The plates are similar in form, having a plurality of equal resistance current paths connecting the power source to a central connecting ring. The connecting rings are secured to the bottom of the inner conductive assembly and the outer cylinder, respectively. A hydraulic actuator is also connected to the bottom of the inner conductor assembly to adjust the pressure applied to the test specimens during testing. The test assembly controls magnetic forces such that the current distribution through the test samples is symmetrical and that contact pressure is not reduced or otherwise disturbed.

Results of Water and Sediment Toxicity Tests and Chemical Analyses Conducted at the Central Shops Burning Rubble Pit Waste Unit, January 1999  

SciTech Connect

The Central Shops Burning Rubble Pit Operable Unit consists of two inactive rubble pits (631-1G and 631-3G) that have been capped, and one active burning rubble pit (631-2G), where wooden pallets and other non-hazardous debris are periodically burned. The inactive rubble pits may have received hazardous materials, such as asbestos, batteries, and paint cans, as well as non-hazardous materials, such as ash, paper, and glass. In an effort to determine if long term surface water flows of potentially contaminated water from the 631-1G, 631-3G, and 631-2G areas have resulted in an accumulation of chemical constituents at toxic levels in the vicinity of the settling basin and wetlands area, chemical analyses for significant ecological preliminary constituents of concern (pCOCs) were performed on aqueous and sediment samples. In addition, aquatic and sediment toxicity tests were performed in accordance with U.S. EPA methods (U.S. EPA 1989, 1994). Based on the results of the chemical analyses, unfiltered water samples collected from a wetland and settling basins located adjacent to the CSBRP Operable Unit exceed Toxicity Reference Values (TRVs) for aluminum, barium, chromium, copper, iron, lead, and vanadium at one or more of the four locations that were sampled. The water contained very high concentrations of clay particles that were present as suspended solids. A substantial portion of the metals were present as filterable particulates, bound to the clay particles, and were therefore not biologically available. Based on dissolved metal concentrations, the wetland and settling basin exceeded TRVs for aluminum and barium. However, the background reference location also exceeded the TRV for barium, which suggests that this value may be too low, based on local geochemistry. The detection limits for both total and dissolved mercury were higher than the TRV, so it was not possible to determine if the TRV for mercury was exceeded. Dissolved metal levels of chromium, copper, iron, lead and vanadium were below the TRVs. Metal concentrations in the sediment exceeded the TRVs for arsenic, chromium, copper, and mercury but not for antimony and lead. The results of the water toxicity tests indicated no evidence of acute toxicity in any of the samples. The results of the chronic toxicity tests indicated possible reproductive impairment at two locations. However, the results appear to be anomalous, since the toxicity was unrelated to concentration, and because the concentrations of pCOCs were similar in the toxic and the non-toxic samples. The results of the sediment toxicity tests indicated significant mortality in all but one sample, including the background reference sediment. When the results of the CSBRP sediment toxicity tests were statistically compared to the result from the background reference sediment, there was no significant mortality. These results suggest that the surface water and sediment at the CSBRP Operable Unit are not toxic to the biota that inhabit the wetland and the settling basin.

PACS software testing  

NASA Astrophysics Data System (ADS)

A PACS in clinical use must provide a high degree of reliability in terms of uptime and data integrity. For a number of reasons, this is difficult to achieve. There may exist, on a PACS network, a multitude of imaging and display sub-systems each with its own interface peculiarities and requirements. Because a PACS is usually a multi-vendor system, the interface problems are complex. Furthermore, once a PACS is in clinical use, the nature of the process level interactions are complicated and random. To improve overall system reliability requires not only rigorous component testing but also a complete system evaluation. A testing methodology for the evaluation of a multi-vendor PACS is being developed at our institution. Key features of this methodology include the design of component and system stress tests, and system boundary tests that stimulate the depletion of critical resources. Preliminary results from running such tests at the University of Pennsylvania Medical Center are presented.

Air gun test evaluation  

SciTech Connect

A mechanical shock testing apparatus is used for testing the response of components subject to large accelerations in hostile environments. The test acceleration is provided by the impact of a bullet against a plate on which the component to be tested is mounted. This report describes a series of experiments that were performed to determine the dependence of the air gun test apparatus performance on incremental changes in the hardware configurations, changes in the pressure used to drive the bullet, and different accelerometers. The effect of variation of these experimental factors on the measured acceleration was determined using a Taguchi screening experimental design. Experimental settings were determined that can be used to operate the tester with a measured output within acceleration specifications.

Association testing with Mendel.  

PubMed

This report presents an overview of association testing strategies from a user's perspective, with particular attention to the capabilities of the computer program Mendel. Association testing is driven by the nature of the study sample, the nature of the disease trait, and the kind of markers employed. The practicing statistician must also choose whether to conduct parametric or nonparametric tests. Because of the complexities involved, Mendel offers users several analysis options. The different options are tied together by shared input and output conventions and a shared language for defining models. Mendel also features new statistics and theory found in no other genetics software. The most important innovations include: association testing by penetrance estimation, expansion of matched-pair designs to permutation unit designs, and a rigorous implementation of the measured genotype approach for quantitative trait loci. This report explains how Mendel imputes allele counts and conducts both asymptotic and permutation tests in the measured genotype framework. PMID:15834862

Antifungal susceptibility testing.  

PubMed

Unlike antibacterial susceptibility testing, reliable antifungal susceptibility testing is still largely in its infancy. Many methods have been described, but they produce widely discrepant results unless such factors as pH, inoculum size, medium formulation, incubation time, and incubation temperature are carefully controlled. Even when laboratories agree upon a common method, interlaboratory agreement may be poor. As a result of numerous collaborative projects carried out both independently and under the aegis of the Subcommittee on Antifungal Susceptibility Testing of the National Committee for Clinical Laboratory Standards, the effects of varying these factors have been extensively studied and a standard method which minimizes interlaboratory variability during the testing of Candida spp. and Cryptococcus neoformans has been proposed. This review summarizes this work, reviews the strengths and weaknesses of the proposed susceptibility testing standard, and identifies directions for future work. PMID:8269392

Rapid prototype and test  

SciTech Connect

In order to support advanced manufacturing, Sandia has acquired the capability to produce plastic prototypes using stereolithography. Currently, these prototypes are used mainly to verify part geometry and ``fit and form`` checks. This project investigates methods for rapidly testing these plastic prototypes, and inferring from prototype test data actual metal part performance and behavior. Performances examined include static load/stress response, and structural dynamic (modal) and vibration behavior. The integration of advanced non-contacting measurement techniques including scanning laser velocimetry, laser holography, and thermoelasticity into testing of these prototypes is described. Photoelastic properties of the epoxy prototypes to reveal full field stress/strain fields are also explored.

Fiber optic testing laboratory  

NASA Astrophysics Data System (ADS)

The TIA and the EIA have developed a set of standardized test procedures for optical loss of fiber, cables, connectors and splices under many varying environmental conditions called FOTPs. We have implemented the experimental setup corresponding to four of these FOTPs. The firs test allows to measure the change in optical transmittance for devices used in optical fiber systems, between an initial condition and a new condition induced by exposure of the device to physical or environmental changes. The second test determines the quality of the ends for both, bare and connectorized fiber using an interferometric microscope. The third one measures the cutoff wavelength for single-mode fibers. Finally, the capacity of a fiber cable to resist simultaneously torsion and traction are determined measuring the changes in optical transmittance when the cable is properly installed in a special tower. This work is considered as the first step towards the settlement of a regional center for fiber optic testing.

Manipulator comparative testing program  

SciTech Connect

The Manipulator Comparative Testing Program examined differences among manipulator systems from the United States and Japan. The manipulator systems included the Meidensha BILARM 83A, the Model M-2 of Central Research Laboratories Division of Sargent Industries (CRL), and the GCA Corporation PaR Systems Model 6000. The site of testing was the Remote Operations Maintenance Demonstration (ROMD) facility, operated by the Fuel Recycle Division in the Consolidated Fuel Reprocessing Program at the Oak Ridge National Laboratory (ORNL). In all stages of testing, operators using the CRL Model M-2 manipulator had consistently lower times to completion and error rates than they did using other machines. Performance was second best with the Meidensha BILARM 83A in master-slave mode. Performance with the BILARM in switchbox mode and the PaR 6000 manipulator was approximately equivalent in terms of criteria recorded in testing. These data show no impact of force reflection on task performance.

Tests of adrenal insufficiency  

PubMed Central

AIM—In suspected adrenal insufficiency, the ideal test for assessing the hypothalamo-pituitary-adrenal axis is controversial. Therefore, three tests were compared in patients presenting with symptoms suggestive of adrenal insufficiency.?METHOD—Responses to the standard short Synacthen test (SSST), the low dose Synacthen test (LDST), and the 08:00 hour serum cortisol concentration were measured in 32 patients. A normal response to the synacthen test was defined as a peak serum cortisol of ? 500 nmol/l and/or incremental concentration of ? 200 nmol/l. The sensitivity and specificity of the 08:00 hour serum cortisol concentration compared with other tests was calculated.?RESULTS—Three patients had neither an adequate peak nor increment after the SSST and LDST. All had a serum 08:00 hour cortisol concentration of < 200 nmol/l. Eight patients had abnormal responses by both criteria to the LDST but had normal responses to the SSST. Three reported amelioration of their symptoms on hydrocortisone replacement. Twenty one patients had a normal response to both tests (of these, 14 achieved adequate peak and increment after both tests and seven did not have an adequate peak after the LDST but had a normal increment). The lowest 08:00 hour serum cortisol concentration above which patients achieved normal responses to both the LDST and SSST was 500 nmol/l. At this cut off value (compared with the LDST), the serum 08:00 hour cortisol concentration had a sensitivity of 100% but specificity was only 33%. ?CONCLUSION—The LDST revealed mild degrees of adrenal insufficiency not detected by the SSST. The value of a single 08:00 hour serum cortisol concentration is limited.??

Comprehensive test ban negotiations  

NASA Astrophysics Data System (ADS)

Although it has been a stated policy goal of American and Soviet leaders since 1958 (with the exception of Ronald Reagan), the world today is still without a Comprehensive Test Ban Treaty. Throughout their history, test an negotiatins have been plagued by a number of persistent problems. Chief among these is East-West differences on the verification question, with the United States concerned about the problem of possible Soviet cheating and the USSR concerned about the protection of its national sovereignty. In addition, internal bureaucratic politics have played a major role in preventing the successful conclusion of an agreement. Despite these problems, the superpowers have concluded several significant partial meausres: a brief (1958-1961) total moratorium on nuclear weapons tests; the Limited Test Ban Treaty of 1963, banning tests in the air, water and outer space; the Threshold Test Ban Treaty of 1974 (150 KT limit on underground explosions); and the Peaceful Nuclear Explosions Treaty of 1976 (150 KT limit on individal PNEs). Today, the main U.S. objections to a CTBT center is the nuclear weapons laboratories, the Department of Energy, and the Pentagon, who all stress the issues of stockpile reliability and verification. Those who remain committed to a CTBT emphasize and the potential political leverage it offers in checking both horizontal and vertical proliferation.

Diesel Engine Idling Test  

SciTech Connect

In support of the Department of Energy’s FreedomCAR and Vehicle Technology Program Office goal to minimize diesel engine idling and reduce the consumption of millions of gallons of diesel fuel consumed during heavy vehicle idling periods, the Idaho National Laboratory (INL) conducted tests to characterize diesel engine wear rates caused by extended periods of idling. INL idled two fleet buses equipped with Detroit Diesel Series 50 engines, each for 1,000 hours. Engine wear metals were characterized from weekly oil analysis samples and destructive filter analyses. Full-flow and the bypass filter cartridges were removed at four stages of the testing and sent to an oil analysis laboratory for destructive analysis to ascertain the metals captured in the filters and to establish wear rate trends. Weekly samples were sent to two independent oil analysis laboratories. Concurrent with the filter analysis, a comprehensive array of other laboratory tests ascertained the condition of the oil, wear particle types, and ferrous particles. Extensive ferrogram testing physically showed the concentration of iron particles and associated debris in the oil. The tests results did not show the dramatic results anticipated but did show wear trends. New West Technologies, LLC, a DOE support company, supplied technical support and data analysis throughout the idle test.

Automation of mechanical testing  

SciTech Connect

This publication, Automation of Mechanical Testing, contains papers presented at the symposium of the same name, held in Pittsburgh, PA on 21 May 1992. The symposium was sponsored by ASTM Committee E-28 on Mechanical Testing. David T. Heberling, Armco Steel Co., L.P., Middletown Works Metallurgical Laboratory, Middletown, OH, presided as symposium chairman and is editor of the resulting publication. Hopefully, the initial flurry of activity has now subsided enough that the 90s can be a decade of maturing and standardization of automated test procedures. To help achieve this goal, the authors present in this STP nine technical papers on the automation of mechanical testing. The first five form a primer for those preparing to implement automated testing. These papers consist of information obtained the hard way--from experience with automation projects. Beginning with the fifth, which fits into both categories, the papers focus on specific technical issues and topics, many of which affect or need to be addressed by ASTM standards.

[Pitfall in coagulation tests].  

PubMed

Coagulation assays are prone to pre-analytical problems and results may be influenced by varying clinical and pharmaceutical aspects. Particularly anticoagulants interact with coagulation testing in many ways. Thromboplastin time will be prolonged dose-dependently in patients taking vitamin K antagonists; moreover the new oral anticoagulants have been shown to have variable impact on the results of the thromboplastin time as well as on other coagulation tests, depending on the mechanism of action of these new drugs as well as on the mechanism of the coagulation test. When measuring anti-Xa activity it should be realised that all drugs with anti-Xa activity will influence the result, which means not only heparins but also the new anti-Xa inhibitors. Respective calibration curves are an indispensable condition to provide the clinician with valuable results. On the other hand this implies that the laboratory knows which anticoagulant is given to the patient. This is an example among others that clinical aspects are important to know for proper interpretation of the results of coagulation testing. Other examples are e. g. bleeding disorders, actual bleeding status or thromboembolic events. Several cases are discussed which exemplify possible pitfalls in the interpretation of coagulation testing. PMID:23876750

Cylinder test data is reported for commercially available prilled ANFO (ammonium-nitrate/fuel-oil) at 0.93 ,g/cc density and ambient temperature. The tests were four-inch inner diameter, with wall-thickness and length scaled from the standard one-inch test (0.4 inch and 48 inch, respectively). The wall expansion was measured with a rotating mirror streak camera and the velocity was measured by fine-wire pin switches, in the standard manner. The wall expansion trajectory is much smoother than for conventional explosives, which show a pronounced jump-off with subs uent ring-up. This observation is consistent with a broadened detohation shock in the granular bed. ?he data is analyzed for equation-of-state information and JWL parameters are given.

Hydration testing of athletes.  

PubMed

Dehydration not only reduces athletic performance, but also places athletes at risk of health problems and even death. For athletes, monitoring hydration has significant value in maximising performance during training and competition. It also offers medical personnel the opportunity to reduce health risks in situations where athletes engage in intentional weight loss. Simple non-invasive techniques, including weight monitoring and urine tests, can provide useful information. Bioimpedance methods tend to be easy to use and fairly inexpensive, but generally lack the precision and accuracy necessary for hydration monitoring. Blood tests appear to be the most accurate monitoring method, but are impractical because of cost and invasiveness. Although future research is needed to determine which hydration tests are the most accurate, we encourage sports teams to develop and implement hydration monitoring protocols based on the currently available methods. Medical personnel can use this information to maximise their team's athletic performance and minimise heat- and dehydration-related health risks to athletes. PMID:12457417

NASA Astrophysics Data System (ADS)

A modified plan for the flat plate solar array (FSA) project was implemented. Accomplishments included completion of six arrays containing Block 4 modules, the portable array data logger and a representative sample of Block 1, 2, and 3 modules and were redeployed for continued endurance testing. The portions of the plan which were modified include: (1) a reduction in the number of Block 4 modules deployed; (2) a reduced data acquisition schedule; (3) abandonment of the Table Mountain and Point Vicente sites; and (4) a sample of the modules from the 12 continental remote sites underwent the final test procedures. Current endurance data are presented for the remaining Block 1, 2, and 3 modules. It is indicated that more of these modules have failed or decreased in power output during this period. None of the Block 4 modules under test during this period have failed, but 11 of the 155 deployed modules show reduced power output.

Testing soil for corrosiveness  

SciTech Connect

This article discusses soil conditions and elements that are common to most types of buried or submerged structures. It provides an overview of the parameters which determine the corrosiveness of a soil. Soil resistivity test data is the best data available for determining soil corrosiveness. Analysis of resistivity data should concentrate on changes in resistivity rather than absolute values of resistivity. Chloride concentrations, pH, and total acidity should be known for soil evaluation for most construction materials. Sulfate concentrations and hydroxyl ion concentrations are of concern in dealing with concrete structures. Redox potential sulfides and moisture values should not be used indiscriminately in soil analysis. An experienced corrosion engineer can identify the need for the tests and should supervise testing to ensure a high degree of accuracy.

Automated calorimeter testing system  

SciTech Connect

The Automated Calorimeter Testing System (ACTS) is a portable measurement device that provides an independent measurement of all critical parameters of a calorimeter system. The ACTS was developed to improve productivity and performance of Mound-produced calorimeters. With ACTS, an individual with minimal understanding of calorimetry operation can perform a consistent set of diagnostic measurements on the system. The operator can identify components whose performance has deteriorated by a simple visual comparison of the current data plots with previous measurements made when the system was performing properly. Thus, downtime and out of control'' situations can be reduced. Should a system malfunction occur, a flowchart of troubleshooting procedures has been developed to facilitate quick identification of the malfunctioning component. If diagnosis is beyond the capability of the operator, the ACTS provides a consistent set of test data for review by a knowledgeable expert. The first field test was conducted at the Westinghouse Savannah River Site in early 1990. 6 figs.

Testing for nominal dysphasia.  

PubMed Central

In this paper we have described the construction of a graded naming test that makes the distinction between object and proper names. This distinction was prompted by a single case study of a patient who showed a specific naming impairment for a particular class of proper names. Naming vocabulary was found to be highly correlated with other measures of verbal intelligence and we have discussed the use of the graded naming test as a tool for clinical assessment and diagnosis. The results of the naming test of the left hemisphere group showed that category-specific naming impairment along the object/proper name distinction is relatively uncommon in any gross form. Object naming was most impaired in patients with lesions of the temporal lobe.

AMTEC Module Test Program  

NASA Astrophysics Data System (ADS)

The Alkali Metal Thermal to Electric Converter (AMTEC) is a thermally regenerated sodium concentration cell that statically converts heat directly into electricity. The high efficiency of AMTEC will be useful for power generation in space and terrestrial applications. A series of 6 geometrically similar cells with identical wick structures has been fabricated by Advanced Modular Power Systems (AMPS). Three electrode/current collector designs have been included in the testing matrix. Two cells of each design were built. One cell in each set had a thermocouple installed at the electrode/current collector interface to measure the temperature of the beta-alumina solid electrolyte (BASE) tube. This thermocouple can also be used to measure the voltage at the cathode since its sheath is electrically isolated from ground. The BASE tubes used to build the cells were all from the same production lot. This testing program represents a unique opportunity to comparatively evaluate the performance of geometrically identical cells with different electrode/collector systems. The electrical and life performance can be evaluated as a function of electrode design for a series of cells fabricated to the same set of specifications. This testing will also be used to evaluate wick stability and the ability to make wicks with consistent performance parameters. The tungsten/rhodium (W/Rh) electrodes and molybdenum (Mo) current collectors were produced at JPL and the cells were fabricated at AMPS. Initial performance testing was done before shipping the cells to Phillips Laboratory for long term testing. The initial performance of these cells will be discussed in this paper. Another paper in this proceedings will discuss a more detailed testing and evaluation program.

Flame Tests Performed Safely  

NSDL National Science Digital Library

The trend toward inquiry-based learning is providing today's students with a more enriching education. When implementing inquiry it is important to recognize the great number of safety concerns that accompany this paradigm shift. Fortunately, with some consideration, teachers can shape students' laboratory experiments into safe and valuable learning experiences. One very popular demonstration is the flame test. The author provides a safe and effective alternative to the traditional flame test without the traditional use of methanol, and provides strategies that allow students to safely gain a better understanding of the atomic structure, the nature of light, and the electromagnetic spectrum.

Vehicle Disturbance Test  

NASA Astrophysics Data System (ADS)

The purpose of the VDT is to measure and characterize uncompensated environmental disturbances acting upon the HST during normal operation. The VDT is a passive test {not a forced-response test} used to obtain signatures for both externally induced {e.g. SCM, SA-3, SSM thermal gradients} and internally induced {e.g. HGA, RWA, COS and WFC3 mechanisms} disturbances affecting HST LOS pointing. The disturbances observed will be used as the nominal on-orbit disturbances in pointing control simulations until the next VDT is run. The test occurs after release, and most of the VDT can be run during the BEA period. The ?V1 sunpoint portion of the VDT usually occurs after the BEA period is complete. The VDT shall consist of two separate tests that need not occur consecutively. The overall duration of the VDT is at least 13 orbits of spacecraft time including {1} at least 8 orbits at +V3 sunpoint after achieving thermal equilibrium {at least 36-hours at +V3 sunpoint} and three out of 8-orbits have RWA Friction Compensation turned Off, and {2} at least 5 orbits at ?V1 sunpoint {all or part of this segment have RWA Friction Compensation turned Off}. At the beginning of each test, the attitude control law gains are switched to maneuver gains, and the gyros are commanded to low mode. The nominal attitude control law configuration will be restored at the end of each test. Each test is initiated via SMS execution of stored program macros in the HST flight computer to switch the attitude control law gains to low-bandwidth maneuver gains, command the gyros into low mode, terminate Velocity aberration and parallax {VAP} processing, and manage the status of on-board RWA Friction Compensation. The nominal attitude control law configuration will be restored at the end of each test via SMS execution of stored program macros. The stored program command macros are developed specifically for the VDT by the Flight Software and Pointing Control System groups.;

HYDRATE CORE DRILLING TESTS  

SciTech Connect

The ''Methane Hydrate Production from Alaskan Permafrost'' project is a three-year endeavor being conducted by Maurer Technology Inc. (MTI), Noble, and Anadarko Petroleum, in partnership with the U.S. DOE National Energy Technology Laboratory (NETL). The project's goal is to build on previous and ongoing R&D in the area of onshore hydrate deposition. The project team plans to design and implement a program to safely and economically drill, core and produce gas from arctic hydrates. The current work scope includes drilling and coring one well on Anadarko leases in FY 2003 during the winter drilling season. A specially built on-site core analysis laboratory will be used to determine some of the physical characteristics of the hydrates and surrounding rock. Prior to going to the field, the project team designed and conducted a controlled series of coring tests for simulating coring of hydrate formations. A variety of equipment and procedures were tested and modified to develop a practical solution for this special application. This Topical Report summarizes these coring tests. A special facility was designed and installed at MTI's Drilling Research Center (DRC) in Houston and used to conduct coring tests. Equipment and procedures were tested by cutting cores from frozen mixtures of sand and water supported by casing and designed to simulate hydrate formations. Tests were conducted with chilled drilling fluids. Tests showed that frozen core can be washed out and reduced in size by the action of the drilling fluid. Washing of the core by the drilling fluid caused a reduction in core diameter, making core recovery very difficult (if not impossible). One successful solution was to drill the last 6 inches of core dry (without fluid circulation). These tests demonstrated that it will be difficult to capture core when drilling in permafrost or hydrates without implementing certain safeguards. Among the coring tests was a simulated hydrate formation comprised of coarse, large-grain sand in ice. Results with this core showed that the viscosity of the drilling fluid must also be carefully controlled. When coarse sand was being cored, the core barrel became stuck because the drilling fluid was not viscous enough to completely remove the large grains of sand. These tests were very valuable to the project by showing the difficulties in coring permafrost or hydrates in a laboratory environment (as opposed to a field environment where drilling costs are much higher and the potential loss of equipment greater). Among the conclusions reached from these simulated hydrate coring tests are the following: Frozen hydrate core samples can be recovered successfully; A spring-finger core catcher works best for catching hydrate cores; Drilling fluid can erode the core and reduces its diameter, making it more difficult to capture the core; Mud must be designed with proper viscosity to lift larger cuttings; and The bottom 6 inches of core may need to be drilled dry to capture the core successfully.

Micromachine friction test apparatus  

DOEpatents

A microelectromechanical (MEM) friction test apparatus is disclosed for determining static or dynamic friction in MEM devices. The friction test apparatus, formed by surface micromachining, is based on a friction pad supported at one end of a cantilevered beam, with the friction pad overlying a contact pad formed on the substrate. A first electrostatic actuator can be used to bring a lower surface of the friction pad into contact with an upper surface of the contact pad with a controlled and adjustable force of contact. A second electrostatic actuator can then be used to bend the cantilevered beam, thereby shortening its length and generating a relative motion between the two contacting surfaces. The displacement of the cantilevered beam can be measured optically and used to determine the static or dynamic friction, including frictional losses and the coefficient of friction between the surfaces. The test apparatus can also be used to assess the reliability of rubbing surfaces in MEM devices by producing and measuring wear of those surfaces. Finally, the friction test apparatus, which is small in size, can be used as an in situ process quality tool for improving the fabrication of MEM devices.

[Chronic urticaria. Provocation test].  

PubMed

Sixty patients of ages ranging from 11 to 64, with chronic urticaria from 2 months to 50 years duration, were studied with the provocation test. We found responses in 33.3% of patients. Tartrazine was the most common inducer, specially in those patients sensitive to aspirin with increased salicilate blood levels. As we did not use aspirin as inducer the results with tartrazine are more relevant and can be used to detect a positive response to aspirin. The relation between tartrazine and aspirin was not observed in patients with pressure or cholinergic urticaria. The provocation test is most useful in patients with chronic urticaria of unknown cause. 4 hydroxybenzoic acid and sodium acid and sodium benzoate were the more common inducers in the latter patients. We feel that the provocation test is a useful tool to study patients with chronic urticaria. Tartrazine, 4 hydroxybenzoic acid, sodium benzoate, tiramin and penicilin are included in the test. The responders should eliminate the offender from their diet. PMID:1035401

Soils contaminated with petroleum by-products can now be effectively remediated using a variety of technologies. Among these are in-situ bioremediation, land farming, and landfill/replacing of soil. The range of efficiencies and cost effectiveness of these technologies has been well documented. Exsorbet Plus is showing promise as an in-situ bioremediation agent. It is made of naturally grown Spaghnum Peat Moss which has been activated for encapsulation and blended with nitrogen-rich fertilizer. In its initial field test in Caracas, Venezuela, it was able to remediate crude oil-contaminated soil in 90 days at less than half of the cost of competing technologies. Waste Solutions, Corp and the US Department of Energy signed a Cooperative Research and Development Agreement to test Exsorbet Plus at the Rocky Mountain Oilfield Testing Center near Casper, Wyoming. As part of the test, soil contaminated with crude oil was treated with Exsorbet Plus to aid the in-situ bioremediation process. Quantitative total petroleum hydrocarbon (TPH) measurements were acquired comparing the performance of Exsorbet Plus with an adjacent plot undergoing unaided in-situ bioremediation.
