    For the next 30 years, the main activities at the US Department of Energy (DOE) Hanford Site will involve the management, handling, and cleanup of toxic substances. If the DOE is to meet its high standards of safety, the thousands of workers involved in these activities will need systematic training appropriate to their tasks and the risks associated with these tasks. Furthermore, emergency response for DOE shipments is the primary responsibility of state, tribal, and local governments. A collaborative training initiative with the DOE will strengthen emergency response at the Hanford Site and within the regional communities. Local and international labor has joined the Hazardous Materials Management and Emergency Response (HAMMER) partnership, and will share in the HAMMER Training Center core programs and facilities using their own specialized trainers and training programs. The HAMMER Training Center will provide a centralized regional site dedicated to the training of hazardous material, emergency response, and fire fighting personnel.

    A mechanism for drilling or coring by a combination of sonic hammering and rotation. The drill includes a hammering section with a set of preload weights mounted atop a hammering actuator and an axial passage through the hammering section. In addition, a rotary section includes a motor coupled to a drive shaft that traverses the axial passage through the hammering section. A drill bit is coupled to the drive shaft for drilling by a combination of sonic hammering and rotation. The drill bit includes a fluted shaft leading to a distal crown cutter with teeth. The bit penetrates sampled media by repeated hammering action. In addition, the bit is rotated. As it rotates the fluted bit carries powdered cuttings helically upward along the side of the bit to the surface.

  9. Hammering towards QED

    2016-01-01

    Full Text Available This paper surveys the emerging methods to automate reasoning over large libraries developed with formal proof assistants. We call these methods hammers. They give the authors of formal proofs a strong "one-stroke" tool for discharging difficult lemmas without the need for careful and detailed manual programming of proof search.The main ingredients underlying this approach are efficient automatic theorem provers that can cope with hundreds of axioms, suitable translations of richer logics to their formalisms, heuristic and learning methods that select relevant facts from large libraries, and methods that reconstruct the automatically found proofs inside the proof assistants.We outline the history of these methods, explain the main issues and techniques, and show their strength on several large benchmarks. We also discuss the relation of this technology to the QED Manifesto and consider its implications for QED-style efforts.

    Mazaika, R.; Cadwell, L.L.

    1994-07-01

    Habitat quality for ferruginous hawks (Buteo regalis) is largely determined by availability of nest sites and adequate prey base. A limitation of one of these will limit the number of hawks in an area. In general, ferruginous hawks are adaptable to various nesting substrates and will nest in proximity to other closely related sympatric species (e.g., red-tailed hawk, Swainson`s hawk). This analysis focused on an assessment of prey base availability and habitat disturbance in the vicinity of historic nest sites and small mammal trap sites on the Yakima Training Center (YTC) in Washington State. The primary ground-disturbing activities on the YTC are associated with military training, fire, and grazing. In addition to the direct effect these activities can have on ferruginous hawks, indirect effects may result from changes in composition, density, and structure of vegetation that subsequently alter faunal population numbers and species diversity. A summary of results of small mammal trapping, population estimation, vegetative analysis and disturbance rating at seven trap sites during the time period of June through August of 1993 are presented.

  12. Condensation induced water hammer safety

    Energy Technology Data Exchange (ETDEWEB)

    Gintner, M.A.

    1997-03-10

    Condensation induced water hammer events in piping systems can cause catastrophic steam system failures which can result in equipment damage, personal injury, and even death. As an industry, we have learned to become accustomed to the ''banging'' that we often hear in our steam piping systems, and complacent in our actions to prevent it. It is unfortunate that lives are lost needlessly, as this type of water hammer event is preventable if one only applies some basic principles when operating and maintaining their steam systems. At the U. S. Department of Energy's Hanford Site where I work, there was one such accident that occurred in 1993 which took the life of a former co-worker and friend of mine. Hanford was established as part of the Manhattan Project during World War II. it is a 560 square mile complex located along the banks of the Columbia River in Southeastern Washington State. For almost 45 years, hanford's mission was to produce weapons grade plutonium for our nations defense programs. Today, Hanford no longer produces plutonium, but is focused on site clean-up and economic diversification. Hanford still uses steam for heating and processing activities, utilizing over 20 miles of piping distribution systems similar to those found in industry. Although these aging systems are still sound, they cannot stand up to the extreme pressure pulses developed by a condensation induced water hammer.

    Full Text Available Hydraulic equipment on board ships is common. It assists in the work of: steering gear, pitch propellers, watertight doors, cargo hatch covers, cargo and mooring winches, deck cranes, stern ramps etc. The damage caused by transient flows (which include among others water hammer are often impossible to repair at sea. Hence, it is very important to estimate the correct pressure runs and associated side effects during their design. The presented study compares the results of research on the impact of a simplified way of modeling the hydraulic resistance and simplified effective weighting functions build of two and three-terms on the estimated results of the pressure changes. As it turns out, simple effective two-terms weighting functions are able to accurately model the analyzed transients. The implementation of the presented method will soon allow current automatic protection of hydraulic systems of the adverse effects associated with frequent elevated and reduced pressures.

    2014-10-01

    The HH Seismic hammer is a large, "weight-drop" source for active source seismic experiments. This system provides a repetitive source that can be stacked for subsurface imaging and exploration studies. Although the seismic hammer was designed for seismological studies it was surmised that it might produce energy in the infrasonic frequency range due to the ground motion generated by the 13 metric ton drop mass. This study demonstrates that the seismic hammer generates a consistent acoustic source that could be used for in-situ sensor characterization, array evaluation and surface-air coupling studies for source characterization.

    2012-01-01

    This abstract presents the training approach taken to create a management-centered, experiential learning solution for the Virginia Port Authority's Port Command Center. The resultant tool, called the Command Center Training Tool (C2T2), follows a holistic approach integrated across the training management cycle and within a single environment. The approach allows a single training manager to progress from training design through execution and AAR. The approach starts with modeling the training organization, identifying the organizational elements and their individual and collective performance requirements, including organizational-specific performance scoring ontologies. Next, the developer specifies conditions, the problems, and constructs that compose exercises and drive experiential learning. These conditions are defined by incidents, which denote a single, multi-media datum, and scenarios, which are stories told by incidents. To these layered, modular components, previously developed meta-data is attached, including associated performance requirements. The components are then stored in a searchable library An event developer can create a training event by searching the library based on metadata and then selecting and loading the resultant modular pieces. This loading process brings into the training event all the previously associated task and teamwork material as well as AAR preparation materials. The approach includes tools within an integrated management environment that places these materials at the fingertips of the event facilitator such that, in real time, the facilitator can track training audience performance and resultantly modify the training event. The approach also supports the concentrated knowledge management requirements for rapid preparation of an extensive AAR. This approach supports the integrated training cycle and allows a management-based perspective and advanced tools, through which a complex, thorough training event can be developed.

    1970-02-01

    The Family Planning Association of E1 Salvador is conducting regular week-long courses in family planning for doctors, nurses, social workers and other interested people in El Salvador and the surrounding countries of Guatemala, Honduras, Nicaragua, Costa Rica and Panama. Twelve regional courses on population dynamics, the physiology of reproduction and family planning were held in the academic year 1968-69 at the Faculty of Medicine at the University of El Salvador. Because the demand for places far exceeds the capacity of the Association's training unit, careful selection of candidates is made through consultation with the national family planning associations. Most of those trained are doctors who are being specially equipped to carry out family planning work either as part of government maternal and child health centres or in Association clinics. Many places are also found for nurses and some social workers also attend in order to build up teams for effective clinic management. A few journalists and teachers have been among the trainees as well as groups of religious leaders including Roman Catholics. Lecturers are mainly university personnel drawn from a wide range of disciplines in order to relate family planning not only to health and medicine but also to socio-economic aspects and community welfare. The El Salvador Association, an IPPF member, gets financial support from the Population Council for the training programme but hopes eventually that responsibility for continuing the courses will be taken over by the Government, probably through the Ministry of Education. Another pace-setting activity of the Association has been its close contacts with industry, particulary through the efforts of its President, Mr. Lucio Burgos, General Manager of the El Salvador Power Company, who has gained the interest and support of business and union leaders. Not only do these groups help the work of the Association through fund-raising and public relations activities, but

  2. Development of a Piezoelectric Rotary Hammer Drill

    Domm, Lukas N.

    2011-01-01

    The Piezoelectric Rotary Hammer Drill is designed to core through rock using a combination of rotation and high frequency hammering powered by a single piezoelectric actuator. It is designed as a low axial preload, low mass, and low power device for sample acquisition on future missions to extraterrestrial bodies. The purpose of this internship is to develop and test a prototype of the Piezoelectric Rotary Hammer Drill in order to verify the use of a horn with helical or angled cuts as a hammering and torque inducing mechanism. Through an iterative design process using models in ANSYS Finite Element software and a Mason's Equivalent Circuit model in MATLAB, a horn design was chosen for fabrication based on the predicted horn tip motion, electromechanical coupling, and neutral plane location. The design was then machined and a test bed assembled. The completed prototype has proven that a single piezoelectric actuator can be used to produce both rotation and hammering in a drill string through the use of a torque inducing horn. Final data results include bit rotation produced versus input power, and best drilling rate achieved with the prototype.

  8. Hammering Does Not Fit Fitts' Law

    Directory of Open Access Journals (Sweden)

    Tadej Petrič

    2017-05-01

    Full Text Available While movement is essential to human wellbeing, we are still unable to reproduce the deftness and robustness of human movement in automatons or completely restore function to individuals with many types of motor impairment. To better understand how the human nervous system plans and controls movements, neuromechanists employ simple tasks such as upper extremity reaches and isometric force tasks. However, these simple tasks rarely consider impacts and may not capture aspects of motor control that arise from real-world complexity. Here we compared existing models of motor control with the results of a periodic targeted impact task extended from Bernstein's seminal work: hammering a nail into wood. We recorded impact forces and kinematics from 10 subjects hammering at different frequencies and with hammers with different physical properties (mass and face area. We found few statistical differences in most measures between different types of hammer, demonstrating human robustness to minor changes in dynamics. Because human motor control is thought to obey optimality principles, we also developed a feedforward optimal simulation with a neuromechanically inspired cost function that reproduces the experimental data. However, Fitts' Law, which relates movement time to distance traveled and target size, did not match our experimental data. We therefore propose a new model in which the distance moved is a logarithmic function of the time to move that yields better results (R2 ≥ 0.99 compared to R2 ≥ 0.88. These results support the argument that humans control movement in an optimal way, but suggest that Fitts' Law may not generalize to periodic impact tasks.

    Several changes have occurred in the toilet training (TT) process in recent decades. There has been an increase in the use of daycare as both parents now often work outside the home. Most children attend daycare centers during the period TT usually takes place, and daytime training has shifted from home to daycare. This study is the first to evaluate the way TT is done in daycare centers. A questionnaire was sent to 1,500 daycare centers, of which 429 replied (response rate of 28.6%). The results show that half of the childcare workers base the decision to start TT on readiness signs. The combination of age and readiness signs is used by 44.5%. The majority of the respondents spent more than 1 h per day on TT (81.8%); 79.8% considered that daycare and parents should play an equal role in TT. However, more than a third of the respondents thought that parents pass the responsibility for TT on to daycare and that not enough attention was paid to TT in the home. Most respondents stated that daycare centers had the facilities and means to be able to give the children proper TT (88.5%). Other research indicated that the outcome of TT is not that good overall and that there is room for improvement in the methods used. More research is needed on the role division and on the interaction between daycare and parents and their combined influence on the process and outcome of TT.

    2015-01-01

    The HammerCloud system is used by CERN IT to monitor the status of the Worldwide LHC Computing Grid (WLCG). HammerCloud automatically submits jobs to WLCG computing resources, closely replicating the workflow of Grid users (e.g. physicists analyzing data). This allows computation nodes and storage resources to be monitored, software to be tested (somewhat like continuous integration), and new sites to be stress tested with a heavy job load before commissioning. The HammerCloud system has been in use for ATLAS and CMS experiments for about five years. This summer's work involved porting the HammerCloud suite of tools to the LHCb experiment. The HammerCloud software runs functional tests and provides data visualizations. HammerCloud's LHCb variant is written in Python, using the Django web framework and Ganga/DIRAC for job management.

    1997-10-01

    Electromagnetic surveys were conducted at the Combat Maneuver Training Center (CMTC), Hohenfels, Germany to detect zones where solution cavities develop within lowland areas of the karst valley systems. Geologic models indicate that solution activity occurs at the loess-bedrock interface, and is concentrated along loess-filled fracture trends within the underlying carbonate bedrock. Soil arches that develop along these fracture trends have the potential to fail catastrophically, posing a considerable degree of danger to current training activities. Rapid, continuously recording electromagnetic instruments provide an economical solution for locating zones of high conductivity associated with loess-filled fractures. The electromagnetic surveys delineated high-conductivity trends interpreted to be fracture-controlled. In many instances dolines were observed either along or immediately adjacent to these conductivity lineaments. Analysis of anomaly maps indicate that high-conductivity lineaments are aligned subparallel to fracture and joint orientations measured in nearby outcrops. These associations are the basis for predicting locations where solution cavity collapse and doline development will occur in the future. Information derived from the EM data can be extended directly to hydrologic modeling and to safety programs for military training at the CMTC.

    Background In this article, we reviewed the training results of medical students using the Microvascular Research Center Training Program (MRCP), and proposed an ideal microsurgical training program for all individuals by analyzing the training results of medical students who did not have any surgical experience. Methods As of 2015, a total of 29 medical students completed the MRCP. In the most recent 12 medical students, the number of trials performed for each training stage and the number of rats needed to complete the training were recorded. Additionally, we measured the operating time upon finishing stage 5 for the recent six medical students after it became a current program. Results The average operating time upon finishing stage 5 for the recent six medical students was 120 minutes ± 11 minutes (standard deviation [SD]). The average vascular anastomosis time (for the artery and vein) was 52 minutes ± 2 minutes (SD). For the most recent 12 medical students, there was a negative correlation between the number of trials performed in the non-rat stages (stages 1-3) and the number of rats used in the rat stages (stages 4-5). Conclusion Analysis of the training results of medical students suggests that performing microsurgery first on silicon tubes and chicken wings saves animals' lives later during the training program. We believe that any person can learn the technique of microsurgery by performing 7 to 8 hours of training per day over a period of 15 days within this program setting.

    Concrete is the most common and cheap material for radiation shielding. Compressive strength is the main parameter checked for determining concrete quality. However, for shielding purposes density is the parameter that needs to be considered. X- and -gamma radiations are effectively absorbed by a material with high atomic number and high density such as concrete. The high strength normally implies to higher density in concrete but this is not always true. This paper explains and discusses the correlation between rebound hammer testing and density for concrete containing hematite aggregates. A comparison is also made with normal concrete i.e. concrete containing crushed granite.

  17. Study on liquid-liquid bimetal composite casting hammers

    Full Text Available Crusher hammers for the mineral processing industry must meet the demands of both high wear resistance at the hammer head and high impact toughness at the hammer handle. The crusher hammers made of Hadfield steel have typically low service life of less than 40 hours. To solve the problem, a kind of bimetal crusher hammers made of high chromium cast iron (HCCI and low alloy steel (LAS has been successfully developed by using liquid-liquid composite casting. The microstructure and composite interface bonding was analyzed using optical microscope, SEM, EDX and XRD. Micrographs indicate that the composite interface is metallurgically bonded with a zigzag shape across the boundary and without unbound region or void. After heat treatment, the composite hammers have shown excellent properties. The hardness of HCCI is at least 63 HRC and its ak is greater than 3.5 J.cm-2/FONT>cm-2; the hardness of LAS is greater than 35 HRC and its ak is no less than 80 J.cm-2/FONT>cm-2. Diffusion of elements takes place at the interface and forms a transition region. The micro hardness increases from LAS to the interface and then to HCCI. Wear comparison was made separately between the bimetal composite hammer and a Hadfield steel hammer in two quarries of Jilin province and Liaoning province. The results showed that the liquid-liquid bimetal composite hammers did not have the falling off of hammer head or impact fracture phenomenon, and their service life was 3.75 times as long as that of the Hadfield steel hammers.

    The US Department of Energy`s (DOE`s) Pacific Northwest National Laboratory (PNNL) was tasked in FY97-98 to conduct a multisensor feature extraction project for the Terrain Modeling Project Office (TMPO) of the National Imagery and Mapping Agency (NIMA). The goal of this research is the development of near-autonomous methods to remotely classify and characterize regions of military interest, in support of the TMPO of NIMA. These methods exploit remotely sensed datasets including hyperspectral (HYDICE) imagery, near-infrared and thermal infrared (Daedalus 3600), radar, and terrain datasets. The study site for this project is the US Army`s Yakima Training Center (YTC), a 326,741-acre training area located near Yakima, Washington. Two study areas at the YTC were selected to conduct and demonstrate multisensor feature extraction, the 2-km x 2-km Cantonment Area and the 3-km x 3-km Choke Point area. Classification of the Cantonment area afforded a comparison of classification results at different scales.

    Ultrasonic/sonic rotary-hammer drill (USRoHD) is a recent addition to the collection of apparatuses based on ultrasonic/sonic drill corer (USDC). As described below, the USRoHD has several features, not present in a basic USDC, that increase efficiency and provide some redundancy against partial failure. USDCs and related apparatuses were conceived for boring into, and/or acquiring samples of, rock or other hard, brittle materials of geological interest. They have been described in numerous previous NASA Tech Briefs articles. To recapitulate: A USDC can be characterized as a lightweight, lowpower, piezoelectrically driven jackhammer in which ultrasonic and sonic vibrations are generated and coupled to a tool bit. A basic USDC includes a piezoelectric stack, an ultrasonic transducer horn connected to the stack, a free mass ( free in the sense that it can bounce axially a short distance between hard stops on the horn and the bit), and a tool bit. The piezoelectric stack creates ultrasonic vibrations that are mechanically amplified by the horn. The bouncing of the free mass between the hard stops generates the sonic vibrations. The combination of ultrasonic and sonic vibrations gives rise to a hammering action (and a resulting chiseling action at the tip of the tool bit) that is more effective for drilling than is the microhammering action of ultrasonic vibrations alone. The hammering and chiseling actions are so effective that unlike in conventional twist drilling, little applied axial force is needed to make the apparatus advance into the material of interest. There are numerous potential applications for USDCs and related apparatuses in geological exploration on Earth and on remote planets. In early USDC experiments, it was observed that accumulation of cuttings in a drilled hole causes the rate of penetration of the USDC to decrease steeply with depth, and that the rate of penetration can be increased by removing the cuttings. The USRoHD concept provides for

    To review a decade's experience of a Centers for Disease Control and Preparedness (CDC) funded Center for Public Health Preparedness (hereafter referred to as the Center) and to identify interventions that led to surmounting serious obstacles to achieving the Center's CDC-mandated goals and objectives. The Center's purpose was to train the public health workforce to protect the population from bioterrorism, infectious diseases, and emerging public health threats. This case study used the concepts of the judgment process as developed by Noel Tichy and Warren Bennis to describe the experiences and actions of the Center's leaders. Center staff used public health principles of collaboration, the use of relevant science, and professional training principles in developing and delivering training in epidemiology, behavioral health, crisis leadership, and other fields through distance learning and on-site methods. The study's primary focus was on training in Florida, although the program's reach was national and international. Preparedness training was provided to approximately 10,000 public health officials, primarily drawn from Florida. This is a descriptive study of the Center's activities. The interventions were the steps taken by Center leadership to accomplish the federal and state goals of the program, despite meeting major challenges. The outcome measures were degrees of success, as measured by federal and state officials and other indicators, in delivering high quality training that met CDC and state goals. The Center delivered trainings in fields determined to be needed in Florida and nationally. Participant and observer evaluations were strongly positive. Nationally published papers and presentations contributed to the training evidence base. The Florida Department of Health incorporated the trainings into Florida's mandatory training for Incident Command strike teams. The leaders of the Center and the Florida Department of Health developed a formal statement of

    Full Text Available Business Process Reengineering (BPR is no longer referenced in academic literature with the regularity that it was in the heady days of the mid-nineties but it is still in use in Australian organisations. We are also changing processes radically as new software is implemented or new electronic markets are embraced and the lessons of reengineering can be applied to these process changes. This study makes three main contributions by: (1 investigating the organisational context prior to the embarkation on projects of major change in Australia, (2 testing the validity of a diagnostic proposed by Hammer and Stanton (1995 to be used when assessing the ability of organisations to succeed at reengineering, and (3 examining the impact of the organisational environment prior to change on the outcome of reengineering projects.

  5. HAMMER: Reweighting tool for simulated data samples

    2016-01-01

    Modern flavour physics experiments, such as Belle II or LHCb, require large samples of generated Monte Carlo events. Monte Carlo events often are processed in a sophisticated chain that includes a simulation of the detector response. The generation and reconstruction of large samples is resource-intensive and in principle would need to be repeated if e.g. parameters responsible for the underlying models change due to new measurements or new insights. To avoid having to regenerate large samples, we work on a tool, The Helicity Amplitude Module for Matrix Element Reweighting (HAMMER), which allows one to easily reweight existing events in the context of semileptonic b → q ` ̄ ν ` analyses to new model parameters or new physics scenarios.

    2013-09-01

    Full Text Available In this paper, a new fast and efficient algorithm, Chebyshev super spectral viscosity (SSV method, is introduced to solve the water hammer equations. Compared with standard spectral method, the method's advantage essentially consists in adding a super spectral viscosity to the equations for the high wave numbers of the numerical solution. It can stabilize the numerical oscillation (Gibbs phenomenon and improve the computational efficiency while discontinuities appear in the solution. Results obtained from the Chebyshev super spectral viscosity method exhibit greater consistency with conventional water hammer calculations. It shows that this new numerical method offers an alternative way to investigate the behavior of the water hammer in propellant pipelines.

    This report summarizes and discusses the results of a vegetation survey conducted in 1992 on a portion of the Yakima Training Center (YTC). Pacific Northwest Laboratory (PNL) conducted this survey and a similar survey in 1991 for the U.S. Department of the Army. The objectives of the survey were to evaluate the impact of the herbicide picloram on forbs where aerial applications of picloram were made in 1988, 1989, and 1991 to control knapweed infestations. Forbs are of special interest because they are an important part of the spring and summer diet of the western sage grouse, which is a U.S. Fish and Wildlife Service candidate species for the threatened and endangered list. We also conducted a limited evaluation of the effectiveness of the spray program in controlling the spread of knapweed. Percent plant canopy cover and number of forbs were measured on 120 transacts on the herbicide-treated and untreated control areas. Herbicide treatment in 1991 resulted in a significant reduction in knapweed based on percent cover and density. The treatment areas also all had lower percent canopy cover of perennial forbs and fewer perennial forbs compared to control areas. Canopy cover of shrubs and annual, biennial, and perennial forbs measured on the YTC increased between the 1991 and 1992 survey, which may indicate a recovery of these vegetation types after disturbance. These increases also could reflect the mild 1992 winter and superior growing conditions in the spring of 1992. We recommend that these vegetation transacts continue to be monitored for an additional growing season to evaluate (1) whether knapweed increases to its previous abundance in the 1991 herbicide-treated area, (2) the efficacy of herbicide application on transacts along roadways, and (3) the increase in invasive annuals in herbicide-treated areas and the possible effects on community vegetation structure and sage grouse habitat.

  12. Pump-stopping water hammer simulation based on RELAP5

    2013-12-01

    RELAP5 was originally designed to analyze complex thermal-hydraulic interactions that occur during either postulated large or small loss-of-coolant accidents in PWRs. However, as development continued, the code was expanded to include many of the transient scenarios that might occur in thermal-hydraulic systems. The fast deceleration of the liquid results in high pressure surges, thus the kinetic energy is transformed into the potential energy, which leads to the temporary pressure increase. This phenomenon is called water hammer. Generally water hammer can occur in any thermal-hydraulic systems and it is extremely dangerous for the system when the pressure surges become considerably high. If this happens and when the pressure exceeds the critical pressure that the pipe or the fittings along the pipeline can burden, it will result in the failure of the whole pipeline integrity. The purpose of this article is to introduce the RELAP5 to the simulation and analysis of water hammer situations. Based on the knowledge of the RELAP5 code manuals and some relative documents, the authors utilize RELAP5 to set up an example of water-supply system via an impeller pump to simulate the phenomena of the pump-stopping water hammer. By the simulation of the sample case and the subsequent analysis of the results that the code has provided, we can have a better understand of the knowledge of water hammer as well as the quality of the RELAP5 code when it's used in the water-hammer fields. In the meantime, By comparing the results of the RELAP5 based model with that of other fluid-transient analysis software say, PIPENET. The authors make some conclusions about the peculiarity of RELAP5 when transplanted into water-hammer research and offer several modelling tips when use the code to simulate a water-hammer related case.

    This case study overviews the conversion of provider training of the electronic medical record (EMR) from an instructor-led training (ILT) program to eLearning at an Academic Medical Center (AMC). This conversion provided us with both a useful training tool and the opportunity to maximize efficiency within both our training and optimization team and organization. eLearning Development Principles were created and served as a guide to assist us with designing an eLearning curriculum using a five step process. The result was a new training approach that allowed learners to complete training at their own pace, and even test out of sections based on demonstrated competency. The information we have leads us to believe that a substantial return on our investment can be obtained from the conversion with positive impacts that have served as the foundation for the future of end user EMR training at our AMC.

    2011-01-01

    The objective of this study was to explore the effect that providing distance education courses would have on enrollment in courses offered on the campus of the National Conservation Training Center. This is an exploratory study and the results should be interpreted as preliminary rather than conclusive. The study included two components: analysis of existing training-enrollment data for the time period from October 1, 2007 to June 24, 2009, and a survey of U.S. Fish and Wildlife Service (Service) employees regarding their preferences for onsite training and distance education. The analysis of training-enrollment data included training records for 2,823 Service employees. Using this dataset, we created a database that included region, supervisory status, number of enrollments in online training, instructor-led web-based classes, correspondence courses, courses at the campus of the National Conservation Training Center, and instructor-led courses off campus. Our analyses focused on differences between enrollment in distance education and onsite courses and the effects of regional affiliation, supervisory status, and course format. Generally, the regions closest to the campus had higher enrollment in onsite training and regions farther away had higher enrollment in distance education. Nonsupervisors were more likely to enroll in training on campus and supervisors were more likely to enroll in instructor-led training off site. Enrollment in instructor-led courses was higher than in self-paced courses, although this may result from fewer offerings of self-paced courses. The second component of the study involved a survey of Service employees regarding their preferences for distance education and onsite training. The survey was administered online and 911 Service employees responded. Overall, survey respondents indicated a small preference for onsite training and were more likely to enroll in onsite courses than distance education. When asked to indicate reasons that

    The purpose of this study was to determinate the effect of a 6-week specific-sprinter proprioceptive training program on core stability and gravity center control in sprinters. Thirty-three athletes (age = 21.82 ± 4.84 years, height = 1.76 ± 0.07 m, weight = 67.82 ± 08.04 kg, body mass index = 21.89 ± 2.37 kg · m(-2)) from sprint disciplines were divided into a control (n = 17) and experimental (n = 16) groups. A 30-minute proprioceptive training program was included in the experimental group training sessions, and it was performed for 6 weeks, 3 times each week. This program included 5 exercises with the BOSU and Swiss ball as unstable training tools that were designed to reproduce different moments of the technique of a sprint race. Stability with eyes open (EO) and eyes closed, postural stability, and gravity center control were assessed before and after the training program. Analyses of covariance (α = 0.05) revealed significant differences in stability in the medial-lateral plane with EO, gravity center control in the right direction and gravity center control in the back direction after the exercise intervention in the experimental athletes. Nevertheless, no other significant differences were demonstrated. A sprinter-specific proprioceptive training program provided postural stability with EO and gravity center control measures improvements, although it is not clear if the effect of training would transfer to the general population.

    2014-01-01

    Full Text Available With operating anvil hammers, there are rigid impacts of die tools, and as a result, almost instantaneous impact stops of the falling parts of hammer. Such operating conditions lead to the accelerated breakdowns of rods because of significant wave stresses arising in them. Common differential and integral methods to estimate wave stresses are widespread in engineering practice. However, to use them a researcher has to possess certain skills and special software. We consider the method for estimating the wave stresses in the rods of anvil hammers based on Laplace transforms (LT of wave equation. The article shows a procedure to set up and solve differential wave equations by operator method. These equations describe the wave propagation process of strains and stresses in the rods of anvil hammers with rigid impact and taking into account a damping rod connection with the head of hammer. The method takes into consideration an influence of both piston and rod weights and of mechanical and geometrical characteristics of rod on the stress value in the placement of rod in hammer head. Results analysis shows that a sufficiently efficient method for practical improving the durability of rods is the method of damping impact load on the rod through setting the damping devices in the form either of elastic "pad" of one or another design or of hydraulic shock absorbers in the placement of its connection with the hammer head. In this case there is a change of the wave front, it becomes flatter. It is shown that the stresses in the rod are proportional to the amount of wave stresses because of the own impact of rod and piston, which make a total weight of the system. Effect of piston weight on the stresses value at the rod during impact is directly proportional to the ratio of its weight to the rod weight. The geometric parameters of rod and the speed of the falling parts before the impact also influence on the value of stresses in the rod.The represented

    SUMMARY SETTING Training center on tuberculosis (TB) infection control (IC) for health care workers in the Central Asian Republics region. OBJECTIVE To assess the effects of TB IC training courses conducted at the Tuberculosis Infection Control Training Center in Machiton, Tajikistan. DESIGN Participants who participated in training (n = 89) during the first year of operation (April 2014–February 2015) were invited to participate in a post-training interview. RESULTS Of the 89 participants, 84 (94%) completed the interview and expressed satisfaction with the training. Eighty (95%) participants reported meeting with workplace leadership to discuss the training. Of these, 69 (85%) reported discussing changes required to meet TB IC standards. Self-reported changes in TB IC practices at work facilities post training included the creation of TB IC committees, designation of a TB IC focal person, TB IC planning, policies to separate infectious patients in waiting rooms, provision of masks for infectious patients, development of cough etiquette policies, improved glove availability, hand hygiene programs, and TB IC posters in waiting rooms. CONCLUSIONS Participant satisfaction and reported changes in TB IC activities illustrate the potential of these training courses to improve TB IC in the region. Future training courses may be tailored to specific audiences using a structured conceptual framework to impact administration, budgeting, and facilities management of TB IC practices. PMID:28399974

  6. Optimization of Mud Hammer Drilling Performance--A Program to Benchmark the Viability of Advanced Mud Hammer Drilling

    2006-03-01

    Operators continue to look for ways to improve hard rock drilling performance through emerging technologies. A consortium of Department of Energy, operator and industry participants put together an effort to test and optimize mud driven fluid hammers as one emerging technology that has shown promise to increase penetration rates in hard rock. The thrust of this program has been to test and record the performance of fluid hammers in full scale test conditions including, hard formations at simulated depth, high density/high solids drilling muds, and realistic fluid power levels. This paper details the testing and results of testing two 7 3/4 inch diameter mud hammers with 8 1/2 inch hammer bits. A Novatek MHN5 and an SDS Digger FH185 mud hammer were tested with several bit types, with performance being compared to a conventional (IADC Code 537) tricone bit. These tools functionally operated in all of the simulated downhole environments. The performance was in the range of the baseline ticone or better at lower borehole pressures, but at higher borehole pressures the performance was in the lower range or below that of the baseline tricone bit. A new drilling mode was observed, while operating the MHN5 mud hammer. This mode was noticed as the weight on bit (WOB) was in transition from low to high applied load. During this new ''transition drilling mode'', performance was substantially improved and in some cases outperformed the tricone bit. Improvements were noted for the SDS tool while drilling with a more aggressive bit design. Future work includes the optimization of these or the next generation tools for operating in higher density and higher borehole pressure conditions and improving bit design and technology based on the knowledge gained from this test program.

    The collaborative London based non-governmental organization network ELRHA (Enhancing Learning and Research for Humanitarian Assistance) supports partnerships between higher education institutions and humanitarian organizations worldwide with the objective to enhance the professionalization of the humanitarian sector. While coordination and control of the humanitarian sector has plagued the response to every major crisis, concerns highlighted by the 2010 Haitian earthquake response further catalyzed and accelerated the need to ensure competency-based professionalization of the humanitarian health care work force. The Harvard Humanitarian Initiative sponsored an independent survey of established academically affiliated training centers in North America that train humanitarian health care workers to determine their individual training center characteristics and preferences in the potential professionalization process. The survey revealed that a common thread of profession-specific skills and core humanitarian competencies were being offered in both residential and online programs with additional programs offering opportunities for field simulation experiences and more advanced degree programs. This study supports the potential for the development of like-minded academic affiliated and competency-based humanitarian health programs to organize themselves under ELRHA's regional "consultation hubs" worldwide that can assist and advocate for improved education and training opportunities in less served developing countries.

    With the exponential growth of LHC (Large Hadron Collider) data in the years 2010-2012, distributed computing has become the established way to analyse collider data. The ATLAS experiment Grid infrastructure includes more than 130 sites worldwide, ranging from large national computing centres to smaller university clusters. HammerCloud was previously introduced with the goals of enabling virtual organisations (VO) and site-administrators to run validation tests of the site and software infrastructure in an automated or on-demand manner. The HammerCloud infrastructure has been constantly improved to support the addition of new test workflows. These new workflows comprise validation and integration of the new ATLAS workload and data management systems JEDI and Rucio or the development and tests of new storage access protocols like HTTP/WebDAV using Davix and aria2c. Results of the continuous monitoring of site performances in functional and site stress tests are displayed in newly developed views on the HammerCloud webpages for site and VO administrators. We report on the development, optimisation and results of the various components in the HammerCloud framework.

  14. Do chimpanzees use weight to select hammer tools?

    Directory of Open Access Journals (Sweden)

    Cornelia Schrauf

    Full Text Available The extent to which tool-using animals take into account relevant task parameters is poorly understood. Nut cracking is one of the most complex forms of tool use, the choice of an adequate hammer being a critical aspect in success. Several properties make a hammer suitable for nut cracking, with weight being a key factor in determining the impact of a strike; in general, the greater the weight the fewer strikes required. This study experimentally investigated whether chimpanzees are able to encode the relevance of weight as a property of hammers to crack open nuts. By presenting chimpanzees with three hammers that differed solely in weight, we assessed their ability to relate the weight of the different tools with their effectiveness and thus select the most effective one(s. Our results show that chimpanzees use weight alone in selecting tools to crack open nuts and that experience clearly affects the subjects' attentiveness to the tool properties that are relevant for the task at hand. Chimpanzees can encode the requirements that a nut-cracking tool should meet (in terms of weight to be effective.

  15. Russia’s Cosmonauts Inside the Yuri Gagarin Training Center

    CERN Document Server

    Hall, Rex D; Vis, Bert

    2005-01-01

    With the aid of unique photographs, first-hand interviews and historical resources, Rex Hall, Dave Shayler and Bert Vis explain, for the very first time, how Russian citizens have been selected and trained to fly in space, and how these procedures have changed during the past 40 years. The authors also describe the evolution of the often overlooked ground support infrastructure and how the role of cosmonauts has changed from the very earliest days of the Gagarin era, through the demise of the Soviet Union, to the era of international co-operation and collaboration on programmes such as the International Space Station. The book will provide much important background information and insight to the operational Soviet/Russian manned space programme, already covered in other Springer-Praxis titles, but revealing information and facts not covered elsewhere, and providing a unique reference source for all those who wish to understand the changing role of Russian cosmonauts in today’s global space programme.

    This report covers the work completed during Year One (Year One has a 16 month project period) of a five- year Cooperative Agreement (DE-FC26-03NT41895) between the International Union of Operating Engineers (IUOE) National Hazmat Program (OENHP) and the U. S. Department of Energy (DOE) National Energy Technology Laboratory (NETL). This final technical report is being submitted, as required by the Cooperative Agreement, within 90 (calendar) days after the project period ends (December 31, 2004). The resources allocated to Year One of the Cooperative Agreement were adequate for the completion of the required deliverables. All deliverables have been completed and sent to AAD Document Control as directed in the cooperative agreement. The allocation for Year One required 20-25 trainers to be trained in each of five Train-the-Trainer courses and a total of 6,000 workers trained throughout the country. Through cost savings employed for the scheduling and conduct of Train-the-Trainer, instructor refreshers, and direct training classes, 3171 workers have been trained to date. This total incorporates 159 trainers and members from management, local, county, state and federal organizations identified in the Strategic Plan. The largest percentage of personnel trained is heavy equipment operators, and building engineers, which is the largest targeted population identified under this cooperative agreement. The OENHP, using existing curriculum as appropriate, has modified and developed new training modules that have been used to establish four different levels of training courses. The four courses are: (1) EA 500 Energy Assurance Train-the-Trainer, (2) EA 400 Energy Assurance Instructor Refresher, (3) EA 300 Energy Assurance, and (4) EA 100 Energy Assurance Awareness. Training modules cover topics, such as, but not limited to, facility vulnerability and vulnerability assessment, physical security- heating, ventilation, air conditioning, terrorism awareness, weapons of mass

    2010-06-01

    Construction workers are educated at vocational training centers before they begin their working lives. Future bricklayers and their instructors are exposed to respirable dust and possibly to hazardous respirable crystalline silica from trial mortar. Thirty-six personal air samples were collected at six training centers to estimate exposure to respirable dust for both students and teachers. A selection of 22 samples was analyzed for crystalline silica. Average respirable dust exposures ranged from 0.59 mg/m(3) for teachers to 1.45 mg/m(3) for students performing recycling and cleaning tasks. In 45% of the analyzed samples, respirable crystalline silica was detected. Exposure to silica remained below the Dutch OEL (75 microg/m(3)). Exposure was significantly less for teachers than for students. This effect was found in both types of vocational training centers present in the Netherlands. Dry sweeping, as performed at all locations in this study, contributed considerably to the exposure to respirable dust. A first step in reducing exposure to dust and silica at training centers would therefore be to avoid dry sweeping. The presence of a dust extraction system, although not optimally designed, also significantly lowered exposure. To assess a construction worker's lifetime exposure to respirable dust and crystalline silica, the vocational training period should also be taken into account. Several epidemiological studies have shown that time since first exposure can be an important risk factor for chronic health effects. 2010 Wiley-Liss, Inc.

    This article stresses the importance of the qualification of professionals involved in the feeding of children in daycare centers, such that they offer adequate food and programs are developed in order to foster healthy food habits in infants from birth. Thus, the scope of this paper was to evaluate the impact of a training program for these daycare teachers in their perceptions and practices in infant feeding. A qualitative approach was used to evaluate the impact of training, with the application of the focus group technique. Sixteen groups were created, eight of which were daycare centers with training and eight without training, the average number of participants being 6 to 11 per institution aged between 19 and 66. The discourse of the teachers who took part in the training program is replete with signs of small changes, or at least with the recognition that it is indeed necessary and possible to promote change. The importance of organizing and conducting training programs for the nutritional education of teachers in day care centers is emphasized, with the continuous supervision of the effects of the qualification as a strategy for infant health.

    2013-01-01

    Medical students' effective clinical skills training are an important goal of any medical school. When adequate, graduate doctors will have sufficient skills to consult a patient by taking proper history and conducting appropriate physical examination. The question under scrutiny is the optimal place for providing such training. Since the aim is to graduate general physicians, many literatures highlighted the importance of implementing such training in the primary health care centers. A special clinical skills training program was developed for the Year 4 pre-clerkship medical students of the Arabian Gulf University during the academic year 2011-2012. It was important for these students to acquire certain skills before transferring to the clerkship phase where they deal directly with patients. For the 130 students involved in this study, a self-assessment and clinical exam were conducted at the beginning and end of the program. The study showed that students benefited greatly from this training program with significant differences between their preexisting known skills and clinical skills acquired by the end of the program. Primary care centers are ideal places for optimal training because of small group training setting that is one tutor to two students and of the advantage that students face real patient environment.

  2. A description of manual wheelchair skills training: current practices in Canadian rehabilitation centers.

    Best, Krista L; Routhier, François; Miller, William C

    2015-01-01

    To describe current practices for manual wheelchair (MWC) skills training in Canadian rehabilitation centers. An online survey was sent to practice leaders in occupational (OT) and physical therapy (PT) at 87 Canadian rehabilitation centers. Responses were solicited from individuals who could report about wheelchair skills training at facilities with at least 10 beds designated for rehabilitation. Thirty-four questions asked about: (1) demographics, (2) components of MWC training, (3) amount of MWC skills training, (4) use of validated programs and (5) perceived barriers to using validated programs. Data were analyzed using summary statistics. About 68/87 responses were received primarily from OTs (42/68). Basic MWC skills training (e.g. wheel-locks) was consistently part of clinical practice (45/68), while advanced skills training (e.g. curb-cuts) was rare (8/68). On an average, 1-4 h of training was done (29/68). Validated training programs were used by 16/68, most of whom used them "rarely" (7/16). Common barriers to using validated programs were lack of time (43/68) and resources (39/68). Learning to use a wheelchair is important for those with ambulation impairments because the wheelchair enables mobility and social participation. Providing opportunities for advanced wheelchair skills training may enhance mobility and social participation in a safe manner. Implications for Rehabilitation There is evidence confirming the benefits of a validated wheelchair skills program, yet most clinicians do no not use them. A variety of perceived barriers may help to explain the limited use of existing programs, such as time, resources and knowledge. Effective knowledge translation efforts may help alleviate some of these barriers, and novel wheelchair training approaches may alleviate some burden on clinicians to help accommodate the increasing number of older wheelchair users.

    Nanowires generated considerable interest as nanoscale interconnects and as active components of both electronic and electromechanical devices. However, in many cases, manipulation and modification of nanowires are required to realize their full potential. It is essential, for instance, to control the orientation and positioning of nanowires in some specific applications. This work demonstrates a simple method to reversibly control the shape and the orientation of Ge nanowires by using ion beams. Initially, crystalline nanowires were partially amorphized by 30 keY Ga+-implantation. After amorphization, viscous flow and plastic deformation occurred due to the ion hammering effect, causing the nanowires to bend toward the beam direction. The bending was reversed multiple times by ion-implanting the opposite side of the nanowires, resulting in straightening of the nanowires and subsequent bending in the opposite direction. This ion hammering effect demonstrates the detailed manipulation of nanoscale structures is possible through the use of ion irradiation.

  11. Effect of rotational speed in rotary hammer forging process

    Directory of Open Access Journals (Sweden)

    Hamdy Muhammad M

    2015-01-01

    Full Text Available Rotary press forging (RPF has been used in the last century, but it produces many defects in the forgings. The author has invented the rotary hammer forging (RHF process to reduce such defects. RHF is a multi-axes compression process where the material is partially and incrementally deformed by the action of several repeated hammering blows, while the produced deformation region is swept through the whole area of the workpiece. The aim of the present work is to study the effects of rotational speed on the forgings produced by RPF and RHF to compare between the two processes. It has been found that as the rotational speed increases the mushroom effect is constant in RHF while it is greater and increases in RPF. As the rotational speed increases, the twist angle increases in both RHF and RPF, but it is bigger in RPF. These results demonstrate the benefits of using RHF instead of RPF.

    Imatran Voima Oy, IVO, operates two VVER 440 reactors. Unit 1 has been operating since 1977 and unit 2 since 1981. First damages of the feed water distribution (FWD) pipes were observed in 1989. In closer examinations FWD-pipe T-connection turned out to suffer from severe erosion corrosion damages. Similar damages have been found also in other VVER 440 type NPPs. In 1994 the first new FWD-pipe was replaced and in 1996 extensive water hammer experiments were carried out together with EDO Gidropress in Podolsk. After the first phase of the experiments some fundamental changes were made to the construction of the FWD-pipe. The object of this paper is to give short insight to the design of the new FWD-pipe concentrating on water hammer experiments. (orig.).

    2008-01-01

    In this quasi-experimental study we compared the process and outcome of six experiential Systems-Centered Training (SCT) groups to those of American Group Psychotherapy Association (AGPA) Institute groups from two prior studies (MacKenzie, Dies, Coche, Rutan, & Stone, 1987; Tschuschke & Greene, 2002). The SCT training compared well overall and the results provided preliminary, indirect support for the usefulness of "functional subgrouping" - SCT's conceptual and methodological bridge between the group-as-a-whole and the individual member. However, quasi-experimental design limitations make other interpretations equally plausible. Within-group change in the process variables for the SCT groups was also explored, as well as the relative contributions of these variables to post-training learning outcomes and anxious and depressive experience. The results partly corroborated prior studies, but also suggested that SCT may alter training group dynamics, learning, and emotional experience in ways consistent with SCT theory.

    Forced spirometry is essential for diagnosing respiratory diseases and is widely used across levels of care. However, several studies have shown that spirometry quality in primary care is not ideal, with risks of misdiagnosis. Our objective was to assess the feasibility and performance of a telemedicine-based training and quality assurance program for forced spirometry in primary care. The two phases included (1) a 9-month pilot study involving 15 centers, in which spirometry tests were assessed by the Basque Office for Health Technology Assessment, and (2) the introduction of the program to all centers in the Public Basque Health Service. Technicians first received 4 h of training, and, subsequently, they sent all tests to the reference laboratory using the program. Quality assessment was performed in accordance with clinical guidelines (A and B, good; C-F, poor). In the first phase, 1,894 spirometry tests were assessed, showing an improvement in quality: acceptable quality tests increased from 57% at the beginning to 78% after 6 months and 83% after 9 months (pspirometry tests were assessed after the inclusion of 36 additional centers, maintaining the positive trend (61%, 87%, and 84% at the same time points; pspirometry tests improved in all centers. (2) The program provides a tool for transferring data that allows monitoring of its quality and training of technicians who perform the tests. (3) This approach is useful for improving spirometry quality in the routine practice of a public health system.

  19. Automated Grid Monitoring for the LHCb Experiment Through HammerCloud

    CERN Document Server

    Dice, Bradley

    2015-01-01

    The HammerCloud system is used by CERN IT to monitor the status of the Worldwide LHC Computing Grid (WLCG). HammerCloud automatically submits jobs to WLCG computing resources, closely replicating the workflow of Grid users (e.g. physicists analyzing data). This allows computation nodes and storage resources to be monitored, software to be tested (somewhat like continuous integration), and new sites to be stress tested with a heavy job load before commissioning. The HammerCloud system has been in use for ATLAS and CMS experiments for about five years. This summer's work involved porting the HammerCloud suite of tools to the LHCb experiment. The HammerCloud software runs functional tests and provides data visualizations. HammerCloud's LHCb variant is written in Python, using the Django web framework and Ganga/DIRAC for job management.

    Water hammer can cause serious damage to pumping system and unexpected system pressure rise in the pipeline. In nuclear reactor, water hammer can influence on the integrity of safety related system. Water hammer in nuclear reactor have been caused by voiding in normally water-filled lines, steam condensation line containing both steam and water, as well as by rapid check valve action. Therefore, this study focuses on the water hammer by check valve among the sources of water hammer occurrence and suggests proper methodology for check valve type selection against water hammer. This study focuses on the water hammer by check valve action among the sources of water hammer occurrence and suggests proper methodology for check valve type selection against water hammer. If the inadvertent pump trip or pipe rupture in high velocity and pressure pipe is predicted, the fast response check valve such as tiled disc, dual disc and nozzle check valve should be installed in the system.

    Adequate fixation at the time of cementless stem implantation depends on the operator's experience. An objective evaluation method to determine whether the stem has been appropriately implanted may be helpful. We studied the relationship between the hammering sound frequency during stem implantation and internal stress in a femoral model, and evaluated the possible usefulness of hammering sound frequency analysis for preventing intraoperative fracture. Three types of cementless stem (BiCONTACT®, SL-PLUS®, and AI-Hip®) were used. Surgeons performed stem insertion using a procedure similar to that employed in a routine operation. Stress was estimated by finite element analysis, the hammering force was measured, and frequency analysis of hammering sound data obtained using a microphone. Finite element analysis showed a decrease in the hammering sound frequency with an increase in the estimated maximum stress. When a decrease in frequency was observed, adequate hammering had occurred, and the continuation of hammering risked fracture. Based on the relationship between stress and frequency, the evaluation of changes in frequency may be useful for preventing the development of intraoperative fractures. Using our method, when a decrease in frequency is observed, the hammering force should be reduced. Hammering sound frequency analysis may allow the prediction of bone fractures that can be visually confirmed, and may be a useful objective evaluation method for the prevention of intraoperative periprosthetic fractures during stem insertion.

    Full Text Available A pilot Postharvest Training and Services Center (PTSC was launched in October 2012 in Arusha, Tanzania as part of a United States Agency for International Development (USAID funded project. The five key components of the PTSC are (1 training of postharvest trainers, (2 postharvest training and demonstrations for local small-scale clientele, (3 adaptive research, (4 postharvest services, and (5 retail sales of postharvest tools and supplies. During the years of 2011–2012, a one year e-learning program was provided to 36 young horticultural professionals from seven Sub-Saharan African countries. These postharvest specialists went on to train more than 13,000 local farmers, extension workers, food processors, and marketers in their home countries in the year following completion of their course. Evaluators found that these specialists had trained an additional 9300 people by November 2014. When asked about adoption by their local trainees, 79% reported examples of their trainees using improved postharvest practices. From 2012–2013, the project supported 30 multi-day training programs, and the evaluation found that many of the improved practices being promoted were adopted by the trainees and led to increased earnings. Three PTSC components still require attention. Research activities initiated during the project are incomplete, and successful sales of postharvest goods and services will require commitment and improved partnering.

    To evaluate the effectiveness of patient-centered communication training for military providers who conduct post-deployment health screening. The half-day interactive workshop included simulated Soldier patients using video technology. Using a quasi-experimental design, all health care providers at four military treatment facilities were recruited for data collection during a four- to nine-day site visit (23 trained providers, 28 providers in the control group, and one provider declined to participate). All Soldiers were eligible to participate and were blinded to provider training status. Immediately after screening encounters, providers reported on their identification of mental health concerns and Soldiers reported on provider communication behaviors resulting in 1,400 matched pairs. Electronic health records were also available for 26,005 Soldiers. The workshop was found to increase (1) providers' patient-centered communication behaviors as evaluated by Soldiers; (2) provider identification of Soldier mental health concerns; and (3), related health outcomes including provision of education and referral to a confidential counseling resource. Results are promising, but with small effect sizes and study limitations, further research is warranted. A brief intensive workshop on patient-centered communication tailored to the military screening context is feasible and may improve key outcomes. Copyright © 2016 Elsevier Ireland Ltd.

    Hypothenar hammer syndrome is a rare vascular lesion of the distal ulnar artery in Guyon tunnel caused by acute or repetitive blunt trauma to the hypothenar eminence. Described treatment options vary greatly, from nonoperative management treatments to surgical interventions. The aim of this study was to evaluate the long-term outcomes of patients after surgical reconstruction of the ulnar artery. In this retrospective study, the results of 12 patients treated for hypothenar hammer syndrome were evaluated. Preoperative and postoperative examinations of the hand were recorded. Function impairment was assessed with the "Disabilites of the Arm, Shoulder and Hand" questionnaire. Comparisons were also made based on ulnar artery patency versus occlusion. All patients were evaluated for ulnar artery patency as determined by Allen's test and magnetic resonance angiography. All patients were men with an average age of 42.8 years. In 3 patients, a direct end-to-end anastomosis of the ulnar artery was performed, and 9 patients received a reconstruction with a reverse interpositional vein graft. Nine vascular reconstructions remained patent after a mean follow-up period of 56.9 months. These patients had a complete or at least partial relief of their pain, dysesthesia, and cold intolerance compared with preoperatively. Patients with reoccluded ulnar arteries were statistically significant younger (P = 0.036) than patients with patent ulnar artery. They also had a higher pain level (P = 0.009) and a longer follow-up period (P = 0.036) than those with patent reconstruction. There was a trend for higher functional impairment in patients with reoccluded ulnar artery (P = 0.100). Smoking habits showed no influence on ulnar artery patency. For patients with symptomatic hypothenar hammer syndrome and failed nonoperative treatment, surgical intervention is a good option. After more than 4.5 years after surgery 9 of 12 vascular reconstructions remained patent (75% patency rate

    Water Hammer Phenomena can endanger the integrity of structures leading to a possible failure of pipes in nuclear power plants as well as in many industrial applications. These phenomena can arise in nuclear power plants in the course of transients and accidents induced by the start-up of auxiliary feed water systems or emergency core cooling systems in combination with rapid acting valves and pumps. To contribute to further development and validation of the code ATHLET (Analysis of Thermalhydraulics of Leaks and Transients), an experiment performed in the test facility Pilot Plant Pipework (PPP) at Fraunhofer UMSICHT is simulated using the code version ATHLET 3.0A.

    1992-03-01

    In response to environmental concerns at the Combat Maneuver Training Center (CMTC), Hohenfels, Germany, the US Army 7th Army Training Command commissioned a scientific study by Argonne National Laboratory to investigate specific issues. The study involved three parts: (1) a field study to determine if fog oil and CS (a compound named after its discoverers, B.B. Carson and R.W. Stoughton) were accumulating in the CMTC environment, (2) a screening of selected soil samples for the presence of US Environmental Protection Agency priority pollutants, and (3) a literature review of the health effects of fog oil and CS, as well as a review of training practices at CMTC. No fog oil or fog oil degradation products were detected in any soil, sediment, or vegetation sample collected at CMTC. Trace quantities of one or more priority pollutants were tentatively detected in three of eight soil and sediment samples. However, the priority pollutant concentrations are so low that they pose no environmental or health hazards. No evidence of widespread or significant contamination in the training areas was found. Crucial data needed to fully evaluate both acute and chronic health effects of civilian exposures to CS at CMTC are not available. On the basis of the available literature, long-ten-n health effects in the civilian population near CMTC that could result from the use of fog oil and CS during training activities are believed to be negligible.

The recent developments in the IT space propose a shift to the software defined data centres, in which every layer of the infrastructure can be offered as a service. Testing and monitoring is an integral part of the development, validation and operations of big systems, like the grid. This area is not escaping the paradigm shift and we are starting to perceive as natural the Testing as a Service (TaaS) offerings, which allow testing any infrastructure service, such as the Infrastructure as a Service (IaaS) platforms being deployed in many grid sites, both from the functional and stressing perspectives. This work will review the recent developments in HammerCloud and its evolution to a TaaS conception, in particular its deployment on the Agile Infrastructure platform at CERN and the testing of many IaaS providers across Europe in the context of experiment requirements. The first section will review the architectural changes that a service running in the cloud needs, such an orchestration service or new storage requirements in order to provide functional and stress testing. The second section will review the first tests of infrastructure providers on the perspective of the challenges discovered from the architectural point of view. Finally, the third section will evaluate future requirements of scalability and features to increase testing productivity.

  15. Hammer events, neutrino energies, and nucleon-nucleon correlations

    Weinstein, L B; Piasetzky, E

    2016-01-01

    Neutrino oscillation measurements depend on a difference between the rate of neutrino-nucleus interactions at different neutrino energies or different distances from the source. Knowledge of the neutrino energy spectrum and neutrino-detector interactions are crucial for these experiments. Short range nucleon-nucleon correlations in nuclei (SRC) affect properties of nuclei. The ArgoNeut liquid Argon Time Projection Chamber (lArTPC) observed neutrino-argon scattering events with two protons back-to-back in the final state ("hammer" events) which they associated with SRC pairs. The MicroBoone lArTPC will measure far more of these events. We simulate hammer events using two simple models. We use the well-known electron-nucleon cross section to calculate e-argon interactions where the e- scatters from a proton, ejecting a pi+, and the pi+ is then absorbed on a moving deuteron-like $np$ pair. We also use a model where the electron excites a nucleon to a Delta, which then deexcites by interacting with a second nucle...

  17. INTEGRATED DRILLING SYSTEM USING MUD ACTUATED DOWN HOLE HAMMER AS PRIMARY ENGINE

    Energy Technology Data Exchange (ETDEWEB)

    John V. Fernandez; David S. Pixton

    2005-12-01

    A history and project summary of the development of an integrated drilling system using a mud-actuated down-hole hammer as its primary engine are given. The summary includes laboratory test results, including atmospheric tests of component parts and simulated borehole tests of the hammer system. Several remaining technical hurdles are enumerated. A brief explanation of commercialization potential is included. The primary conclusion for this work is that a mud actuated hammer can yield substantial improvements to drilling rate in overbalanced, hard rock formations. A secondary conclusion is that the down-hole mud actuated hammer can serve to provide other useful down-hole functions including generation of high pressure mud jets, generation of seismic and sonic signals, and generation of diagnostic information based on hammer velocity profiles.

    Chronic ankle instability (CAI) occurs in some people after a lateral ankle sprain and often results in residual feelings of instability and episodes of the ankle's giving way. Compared with healthy people, patients with CAI demonstrated poor postural control and used a more anteriorly and laterally positioned center of pressure (COP) during a single-limb static-balance task on a force plate. Balance training is an effective means of altering traditional COP measures; however, whether the overall location of the COP distribution under the foot also changes is unknown. To determine if the spatial locations of COP data points in participants with CAI change after a 4-week balance-training program. Randomized controlled trial. Laboratory. Thirty-one persons with self-reported CAI. Participants were randomly assigned to a 4-week balance-training program or no balance training. We collected a total of 500 COP data points while participants balanced using a single limb on a force plate during a 10-second trial. The location of each COP data point relative to the geometric center of the foot was determined, and the frequency count in 4 sections (anteromedial, anterolateral, posteromedial, posterolateral) was analyzed for differences between groups. Overall, COP position in the balance-training group shifted from being more anterior to less anterior in both eyes-open trials (before trial = 319.1 ± 165.4, after trial = 160.5 ± 149.5; P = .006) and eyes-closed trials (before trial = 387.9 ± 123.8, after trial = 189.4 ± 102.9; P balance training remained the same in the eyes-open trials (before trial = 214.1 ± 193.3, after trial = 230.0 ± 176.3; P = .54) and eyes-closed trials (before trial = 326.9 ± 134.3, after trial = 338.2 ± 126.1; P = .69). In participants with CAI, the balance-training program shifted the COP location from anterolateral to posterolateral. The program may have repaired some of the damaged sensorimotor system pathways, resulting in a more

    Full Text Available Purpose: To evaluate the effectiveness of a learner-centered, simulation-based training developed to help medical students improve their procedural skills in intubation, arterial line placement, lumbar puncture, and central line insertion. Method: The study participants were second and third year medical students. Anesthesiology residents provided the training and evaluated students’ procedural skills. Two residents were present at each station to train the medical students who rotated through all 4 stations. Pre/posttraining assessment of confidence, knowledge, and procedural skills was done using a survey, a multiple-choice test, and procedural checklists, respectively. Results: In total, 24 students were trained in six 4-hour sessions. Students reported feeling significantly more confident, after training, in performing all 4 procedures on a real patient ( P < .001. Paired-samples t tests indicated statistically significant improvement in knowledge scores for intubation, t (23 = −2.92, P < .001, and arterial line placement, t (23 = −2.75, P < .001. Procedural performance scores for intubation ( t (23 = −17.29, P < .001, arterial line placement ( t (23 = −19.75, P < .001, lumbar puncture ( t (23 = −16.27, P < .001, and central line placement ( t (23 = −17.25, P < .001 showed significant improvement. Intraclass correlation coefficients indicated high reliability in checklist scores for all procedures. Conclusions: The simulation sessions allowed each medical student to receive individual attention from 2 residents for each procedure. Students’ written comments indicated that this training modality was well received. Results showed that medical students improved their self-confidence, knowledge, and skills in the aforementioned procedures.

  6. Teaching Reflections about the Architectural Design of the Vocational Training Centers in Granada

    2016-04-01

    Full Text Available If the specificity of the architectural space is considered as a measuring element in the education scope to value the prominence of teaching throughout history, it is worth mentioning that the configuration of the vocational training center as a first-rate education scenario that arrives half century of delay with respect to schools, has few references of very specific period. At present, they continue excessively contaminated because of the continued struggle for linking them with other education levels. This article is focused on this issue. To that end, by interviewing experienced teachers, we value: a from the most conceptual aspect, elements and architectural spaces that should have those reference centers; b the appropriateness of the arranged spaces, not only those that meet the regulatory requirements but those that meet the criteria of the centers; c to the most specific aspects on the way to optimize the arranged space in order to achieve a larger curricular extent. It concludes with a high positive assessment of the opportunity of having the necessary spaces for teaching, relying more strongly on those favoring the free relationship of students and allowing the permeability among the different disciplines that converge in the center.

    Full Text Available A water hammer can produce severe consequences regarding pipe integrity; simulation thus becomes an es-sential requirement for ensuring proper water distribution system design and operation. This article thus tries to demonstrate the importance of numerical methods in resolving such problems. A Scilab code allowing pressure propagation to be represented using the characteristics’ method applied to a case of classic literature was thus developed for numerically simulating this phenomenon. This method uses a finite difference scheme for resolving mass and momentum equations. The article presents equations governing the problem from the numerical point of view, the phenomenon’s behaviour is analysed and results obtained by the numerical approach (calculating finite differences are compared to those obtained with Scilab and the theoretical solution.

  10. Follow-up of hearing thresholds among forge hammering workers

    Kamal, A.A.; Mikael, R.A.; Faris, R. (Ain Shams Univ., Abbasia, Cairo (Egypt))

    1989-01-01

    Hearing threshold was reexamined in a group of forge hammering workers investigated 8 years ago with consideration of the age effect and of auditory symptoms. Workers were exposed to impact noise that ranged from 112 to 139 dB(A)--at an irregular rate of 20 to 50 drop/minute--and a continuous background noise that ranged from 90 to 94 dB(A). Similar to what was observed 8 years ago, the present permanent threshold shift (PTS) showed a maximum notch at the frequency of 6 kHz and considerable elevations at the frequencies of 0.25-1 kHz. The age-corrected PTS and the postexposure hearing threshold were significantly higher than the corresponding previous values at the frequencies 0.25, 0.5, 1, and 8 kHz only. The rise was more evident at the low than at the high frequencies. Temporary threshold shift (TTS) values were significantly less than those 8 years ago. Contrary to the previous TTS, the present TTS were higher at low than at high frequencies. Although progression of PTS at the frequencies 0.25 and 0.5 kHz was continuous throughout the observed durations of exposure, progression at higher frequencies occurred essentially in the first 10 to 15 years of exposure. Thereafter, it followed a much slower rate. Tinnitus was significantly associated with difficulty in hearing the human voice and with elevation of PTS at all the tested frequencies, while acoustic after-image was significantly associated with increment of PTS at the frequencies 0.25-2 kHz. No relation between PTS and smoking was found. PTS at low frequencies may provide an indication of progression of hearing damage when the sensitivity at 6 and 4 kHz diminishes after prolonged years of exposure. Tinnitus and acoustic after-image are related to the auditory effect of forge hammering noise.

    The Patient Centered Observation Form (PCOF) helps trainees identify and describe specific communication skills and enhance self-awareness about skill use. We studied the effectiveness and ease of use of the Improving Communication Assessment Program (ICAP), an online module that prepares trainees to use the PCOF. Students, residents and medical educators viewed two videos (common and better skill use) of the same interaction and rated each video using the PCOF. Video sequence was randomized. We assessed agreement with experts, ease of use, concepts learned, and areas of confusion. Trainees (211) achieved strong agreement (.83) with experts and were highly satisfied (mean 4.18 out of 5). Viewing the common video first produced higher agreement (.87 vs .79; ES=.4) with experts and greater satisfaction (4.36 vs 4.02, ES .4) than viewing the better video first. Trainees reported diverse areas of learning and minimal confusion. ICAP training to use the PCOF may facilitate teaching and assessment of communication skills and enrich training through peer observation and feedback. We offer several educational strategies. Learning to use the PCOF via the ICAP module may accelerate communication training for medical students, residents, medical educators and practicing clinicians. Copyright © 2015 Elsevier Ireland Ltd.

    Behavioral parent training (BPT) has been shown to be efficacious to improve parenting skills for problematic interactions with adolescents displaying oppositional and antisocial behaviors. Some research suggests that support group curricula might be transferred to the Internet, and some studies suggest that other curriculum designs might also be effective. In this research, a BPT program for parents of at-risk adolescents was tested on the Internet in a randomized trial (N = 307) from computer labs at six community technology centers in or near large metropolitan areas. The instructional design was based on asynchronous scenario-based e-learning, rather than a traditional parent training model where presentation of course material builds content sequentially over multiple class sessions. Pretest to 30-day follow-up analyses indicated significant treatment effects on parent-reported discipline style (Parenting Scale, Adolescent version), child behavior (Eyberg Child Behavior Inventory), and on social cognitive theory constructs of intentions and self-efficacy. The effect sizes were small to medium. These findings suggest the potential to provide effective parent training programs on the Internet.

    Medical emergency situations and even cardiac arrest can occur during treatment of patients in therapeutic hyperbaric chambers just as in other clinical departments; therefore, high quality structured management should be implemented for dealing with emergencies in this special working area. To ensure this the emergency medical treatment should not only be performed according to the current state of medical knowledge but needs to take the special features of the hyperbaric environment including safety aspects into account. This article presents a description of the implementation and effects of routine emergency and resuscitation training at a center for hyperbaric medicine. By simulation of emergencies in a hyperbaric chamber it rapidly became clear that the treatment of medical emergencies and cardiac arrest under hyperbaric conditions has some special features and due to safety aspects cannot always be performed according to current medical guidelines. At the time of this simulation in a real life working environment, previously unknown structural and logistic problems became obvious whereby the solutions contributed to a significant improvement of structural and process quality and could potentially also improve the outcome quality. Furthermore, a positive and lasting learning effect in the fields of quality of resuscitation measures, organization of the workplace, communication skills, logistics and safety aspects was detectable by analyzing participant performance over a period of 4 years. On the part of the participating staff a positive feedback and high acceptance of emergency simulator training was confirmed. Through annual compulsory emergency training of the complete staff of the hyperbaric unit at the actual workplace, a structural and confident approach to dealing with emergencies and resuscitation situations was observed. By the use of on-site simulator training even in specialized hospital units, deficits and tentativeness regarding logistics

    Across the United States, ambulatory surgery centers (ASCs) are increasing in both number and surgical volume. This trend has been the focus of debate regarding reimbursement and patient safety, as well as surgical productivity and efficiency. However, the impact on surgical resident training caused by this shift toward outpatient surgery in nonhospital settings has not been studied. We reviewed data reported by our hospital and by local surgery centers as well as the case logs of the surgical residents at our institution to determine whether a negative effect on resident case volume has occurred. We conducted a retrospective review of our PGY-1 through PGY-3 level surgical residents' case logs for 3 consecutive academic years, from July 2004 through June 2007. We evaluated a group of common outpatient procedures that are now also being performed in stand-alone surgical centers in our area, such as breast biopsies, incision and drainage, hernia repair, colonoscopy, and esophagogastroduodenoscopy (EGD). The data were tallied by academic year and compared over time. In addition, we analyzed data reported to state agencies by our hospital and local surgery centers over the last 6 calendar years for any trends in case volume. By evaluating 2 different independent data sets for the same endpoint, we could evaluate our hypothesis twice. When evaluating state-reported data for the defined cases, a significant decrease was observed in the total number of cases performed at Easton Hospital, Easton, Pennsylvania, each year between 2003 and 2006 (p hernia (p = 0.04), excision of skin lesion (p = 0.0022), and incision/drainage (p outpatient surgery experience from procedures performed at our home institution. With the recent surge of stand-alone surgical centers, many outpatient procedures are being performed outside of the hospital in centers where our residents do not rotate.

    Remote sensing has steadily become an integral part of multiple disciplines, research, and education. Remote sensing can be defined as the process of acquiring information about an object or area of interest without physical contact. As remote sensing becomes a necessity in solving real world problems and scientific questions an important question to consider is why remote sensing training is significant to education and is it relevant to training students in this discipline. What has been discovered is the interest in Science, Technology, Engineering and Mathematics (STEM) fields, specifically remote sensing, has declined in our youth. The Center of Excellence in Remote Sensing Education and Research (CERSER) continuously strives to provide education and research opportunities on ice sheet, coastal, ocean, and marine science. One of those continued outreach efforts are Center for Remote Sensing of Ice Sheets (CReSIS) Middle School Program. Sponsored by the National Science Foundation CReSIS Middle School Program offers hands on experience for middle school students. CERSER and NSF offer students the opportunity to study and learn about remote sensing and its vital role in today's society as it relate to climate change and real world problems. The CReSIS Middle School Program is an annual two-week effort that offers middle school students experience with remote sensing and its applications. Specifically, participants received training with Global Positioning Systems (GPS) where the students learned the tools, mechanisms, and applications of a Garmin 60 GPS. As a part of the program the students were required to complete a fieldwork assignment where several longitude and latitude points were given throughout campus. The students had to then enter the longitude and latitude points into the Garmin 60 GPS, navigate their way to each location while also accurately reading the GPS to make sure travel was in the right direction. Upon completion of GPS training the

    Full Text Available Poststroke hemiplegic patients often show altered weight distribution with balance disorders, increasing their risk of fall. Conventional balance training, though powerful, suffers from scarcity of trained therapists, frequent visits to clinics to get therapy, one-on-one therapy sessions, and monotony of repetitive exercise tasks. Thus, technology-assisted balance rehabilitation can be an alternative solution. Here, we chose virtual reality as a technology-based platform to develop motivating balance tasks. This platform was augmented with off-the-shelf available sensors such as Nintendo Wii balance board and Kinect to estimate one’s center of mass (CoM. The virtual reality-based CoM-assisted balance tasks (Virtual CoMBaT was designed to be adaptive to one’s individualized weight-shifting capability quantified through CoM displacement. Participants were asked to interact with Virtual CoMBaT that offered tasks of varying challenge levels while adhering to ankle strategy for weight shifting. To facilitate the patients to use ankle strategy during weight-shifting, we designed a heel lift detection module. A usability study was carried out with 12 hemiplegic patients. Results indicate the potential of our system to contribute to improving one’s overall performance in balance-related tasks belonging to different difficulty levels.

    Full Text Available Abstract Background Most of the efforts to reduce teenagers' tobacco addiction have focused on smoking prevention and little on smoking cessation. A smoking cessation program (TABADO study, associating pharmacologic and cognitive-behavioural strategy, on a particularly vulnerable population (vocational trainees, was developed. This study aims to evaluate the efficacy of the program which was offered to all smokers in a population aged 15 to 20 years in Vocational Training Centers (VTC. This paper presents the TABADO study protocol. Methods The study is quasi-experimental, prospective, evaluative and comparative and takes place during the 2 years of vocational training. The final population will be composed of 2000 trainees entering a VTC in Lorraine, France, during the 2008-2009 period. The intervention group (1000 trainees benefited from the TABADO program while no specific intervention took place in the "control" group (1000 trainees other than the treatment and education services usually available. Our primary outcome will be the tobacco abstinence rate at 12 months. Discussion If the program proves effective, it will be a new tool in the action against smoking in populations that have been seldom targeted until now. In addition, the approach could be expanded to other young subjects from socially disadvantaged backgrounds in the context of a public health policy against smoking among adolescents.

    To identify the impact of leadership training programs at academic medical centers (AMCs) on physicians' knowledge, skills, attitudes, behaviors, and outcomes. In 2011, the authors conducted a systematic review of the literature, identifying relevant studies by searching electronic databases (MEDLINE, EMBASE, CINAHL, Cochrane Central Register), scanning reference lists, and consulting experts. They deemed eligible any qualitative or quantitative study reporting on the implementation and evaluation of a leadership program for physicians in AMCs. Two independent reviewers conducted the review, screening studies, abstracting data, and assessing quality. The authors initially identified 2,310 citations. After the screening process, they had 11 articles describing 10 studies. Three were controlled before-and-after studies, four were before-and-after case series, and three were cross-sectional surveys. The authors did not conduct a meta-analysis because of the methodological heterogeneity across studies. Although all studies were at substantial risk of bias, the highest-quality ones showed that leadership training programs affected participants' advancement in academic rank (48% versus 21%, P=.005) and hospital leadership position (30% versus 9%, P=.008) and that participants were more successful in publishing papers (3.5 per year versus 2.1 per year, Pleadership programs have modest effects on outcomes important to AMCs. Given AMCs' substantial investment in these programs, rigorous evaluation of their impact is essential. High-quality studies, including qualitative research, will allow the community to identify which programs are most effective.

    The Centers for Disease Control and Prevention funded Preparedness and Emergency Response Learning Centers (PERLCs) across the United States. The PERLCs provide training to state, local, and tribal public health organizations to meet workforce development needs in the areas of public health preparedness and response, specialized training, education, and consultation. Using Donald Kirkpatrick's training evaluation model, the PERLC network established 4 evaluation working groups that developed evaluation criteria to address each level of the model. The purpose of the working groups was to inform and promote center-level and program-level evaluation across the PERLC network; identify common training evaluation methods and measures; and share materials, resources, and lessons learned with state, local, and tribal public health organizations for potential replication. The evaluation of education and training, irrespective of its modality (eg, in-person, online, webinars, seminars, symposia) can be accomplished using Kirkpatrick's 4-level taxonomy. The 4 levels aim to measure the following aspects of training programs: (1) trainees' reaction; (2) knowledge acquired, skills improved, or attitudes changed; (3) behavior changed; and (4) results or impact. To successfully evaluate emergency preparedness training, drills and exercises, it is necessary to understand the fundamental tenets of each level and how to apply each to measure training outcomes. The PERLC evaluators have adopted the basic schema of Kirkpatrick's 4-level model and applied its structure to a wide variety of preparedness and emergency response training and related activities. The PERLC evaluation working groups successfully developed and tested survey methods and instruments for each of the 4 levels of Kirkpatrick's training evaluation model. Each can be used for replication by state, local, and tribal public health professionals.

    A DTH (Down-the-hole) hammer powered by highly pressurized fluid is a drilling tool using the motion of percussion of a drill bit. In retrospect, a DTH by using compressed air as a power source has been widely used in drilling industries such as applications of mining, geothermal etc. On the other hand, another type of a DTH that uses pressurized water, called a water hammer, has recently seen deep drilling applications, while it has been rarely investigated. In this study, we designed a water-powered DTH hammer which mainly consists of several components such as a piston, a poppet valve, a cap and a bit for deep drilling applications. We optimized the components of the hammer on the basis of the results of 1D analysis using commercial software of AMESIM. An experimental study has been also conducted to investigate a performance of the designed water hammer. We measured a pressure distribution inside the hammer system as a function of time, and it thus estimates a frequency of impaction of the bit, which has been also analyzed in frequency domain. In addition, some important parameters have been discussed in conjunction with a limitation of impaction frequency as input pressure. We believe that this study provides design rules of a water-based DTH for deep drilling applications. This work is supported by KITECH of Korean government.

  11. Responses of a Highly Accelerated Life Test System to Impacts from Different Designs of Hammers

    Yeong-Shu Chen

    2014-08-01

    Full Text Available The response of a table to the impact of its driving hammer in the highly accelerated life test (HALT system depends on, among other things, the location of the hammer, the presence of multiple hammers, and the angle at which the hammer is mounted to the table. The present study investigated the response of a table to a variety of impacts from different combinations of hammers. It began with a theoretical analysis of the forces of impact exerted by hammers which led to the calculation of the corresponding displacement. These theoretical calculations revealed the mechanics of the HALT system to help explain the working principles behind this complex system. Then a simulation model was built to check the accuracy of the theoretical results. Finally, the accelerations of a table in a real HALT system were measured. These data showed good agreement with the experimental results and computer simulation. The responses of HALT systems have not been investigated thoroughly to date. The current study can help equipment designers and end users better understand the working principles of this kind of systems. It can be considered a breakthrough in terms of improving the performance of reliability testing with this kind of system.

  12. A review of the design and development processes of simulation for training in healthcare - A technology-centered versus a human-centered perspective.

    Persson, Johanna

    2017-01-01

    This article reviews literature about simulation systems for training in healthcare regarding the prevalence of human-centered approaches in the design and development of these systems, motivated by a tradition in this field of working technology-centered. The results show that the focus on human needs and context of use is limited. It is argued that a reduction of the focus on technical advancements in favor of the needs of the users and the healthcare community, underpinned by human factors and ergonomics theory, is favorable. Due to the low number of identified articles describing or discussing human-centered approaches it is furthermore concluded that the publication culture promotes technical descriptions and summative evaluations rather than descriptions and reflections regarding the design and development processes. Shifting the focus from a technology-centered approach to a human-centered one can aid in the process of creating simulation systems for training in healthcare that are: 1) relevant to the learning objectives, 2) adapted to the needs of users, context and task, and 3) not selected based on technical or fidelity criteria.

    We investigate steam condensation induced water hammer (CIWH) phenomena and present new theoretical results. We use the WAHA3 model based on two-phase flow six first-order partial differential equations that present one dimensional, surface averaged mass, momentum and energy balances. A second order accurate high-resolution shock-capturing numerical scheme was applied with different kind of limiters in the numerical calculations. The applied two-fluid model shows some similarities to Relap5 which is widely used in the nuclear industry to simulate nuclear power plant accidents. This model was validated with different CIWH experiments which were performed in the PMK-2 facility, which is a full-pressure thermo-hydraulic model of the nuclear power plant of VVER-440/312 type in the Energy Research Center of the Hungarian Academy of Sciences in Budapest and in the Rosa facility in Japan. In our recent study we show the first part of a planned large database which will give us the upper and lower flooding mass flow ...

    2012-12-01

    With the exponential growth of LHC (Large Hadron Collider) data in 2011, and more coming in 2012, distributed computing has become the established way to analyse collider data. The ATLAS grid infrastructure includes almost 100 sites worldwide, ranging from large national computing centers to smaller university clusters. These facilities are used for data reconstruction and simulation, which are centrally managed by the ATLAS production system, and for distributed user analysis. To ensure the smooth operation of such a complex system, regular tests of all sites are necessary to validate the site capability of successfully executing user and production jobs. We report on the development, optimization and results of an automated functional testing suite using the HammerCloud framework. Functional tests are short lightweight applications covering typical user analysis and production schemes, which are periodically submitted to all ATLAS grid sites. Results from those tests are collected and used to evaluate site performances. Sites that fail or are unable to run the tests are automatically excluded from the PanDA brokerage system, therefore avoiding user or production jobs to be sent to problematic sites.

    An impact hammer test of the full-scale mock-up of the ITER blanket remote handling system (BRHS) was carried out to validate the results of the seismic analysis of the BRHS which were performed using a finite element (FE) model. As the FE analysis of the BRHS predicted a vertical mode ∼8 Hz, which coincides with a major natural frequency of the vacuum vessel of ITER, evaluating the dynamic response of the BRHS experimentally and measuring the system's damping is indispensable in verifying the structural design of the system. Recent preliminary impact testing on the full-scale mock-up of the BRHS showed that the mock-up has a vertical major natural mode having a natural frequency of ∼7.5 Hz and a damping ratio of 0.5%. Several other major natural modes having frequencies less than 10 Hz were found to have damping ratios ranging from 0.2% to 2%. It was confirmed that the natural major frequencies obtained in the experiments are in agreement with the major frequencies obtained via analysis.

    Fatigue affects the capacity of muscles to generate forces and is associated with characteristic changes in EMG signals. It may also influence interjoint and intermuscular coordination. To understand better the global effects of fatigue on multijoint movement, we studied movement kinematics and EMG changes in healthy volunteers asked to hammer repetitively. Movement kinematics and the activity of 20 muscles of the arm, trunk, and leg were recorded before and after subjects became fatigued (as measured using a Borg scale). When fatigue was reached, maximal grip strength and elbow range of motion decreased while the EMG amplitude of the contralateral external oblique muscle was increased. Fatigue did not affect shoulder and wrist kinematics or movement frequency. Results suggest that fatigue influences motion at both local and global levels. Specifically, interjoint and intermuscular coordination adapt to compensate for local effects of fatigue and to maintain key movement characteristics, such as the trajectory of the end effector and the movement frequency. Nonlocal compensations may be a focus of future studies of how fatigue affects complex movements such as those typically performed in the workplace.

    2003-01-01

    To paraphrase Abraham Maslow: If the only tool you have is a hammer, every problem looks like a nail. We have a B-spline fitter customized for 3D color data, and many problems in color management can be solved with this tool. Whereas color devices were once modeled with extensive measurement, look-up tables and trilinear interpolation, recent improvements in hardware have made B-spline models an affordable alternative. Such device characterizations require fewer color measurements than piecewise linear models, and have uses beyond simple interpolation. A B-spline fitter, for example, can act as a filter to remove noise from measurements, leaving a model with guaranteed smoothness. Inversion of the device model can then be carried out consistently and efficiently, as the spline model is well behaved and its derivatives easily computed. Spline-based algorithms also exist for gamut mapping, the composition of maps, and the extrapolation of a gamut. Trilinear interpolation---a degree-one spline---can still be used after nonlinear spline smoothing for high-speed evaluation with robust convergence. Using data from several color devices, this paper examines the use of B-splines as a generic tool for modeling devices and mapping one gamut to another, and concludes with applications to high-dimensional and spectral data.

    2009-01-01

    Concrete cutting in construction is a major source of exposure to respirable crystalline silica. To reduce exposures, local exhaust ventilation (LEV) may be integrated into the hand tools used in concrete cutting. Volunteers from the New England Laborers Training Center participated in a field study focused on the use of LEV on concrete-cutting hammer drills. A randomized block design field experiment employing four workers measured the efficacy of four hood-vacuum source combinations compared with no LEV in reducing dust and silica exposures. Using four-stage personal cascade impactors (Marple 294) to measure dust exposure, a total of 18 personal samples were collected. Reductions of over 80% in all three biologically relevant size fractions of dust (inhalable, thoracic, and respirable) were obtained by using any combination of hood and vacuum source. This study found that respirable dust concentrations were reduced from 3.77 mg/m(3) to a range of 0.242 to 0.370 mg/m(3); thoracic dust concentrations from 12.5 mg/m(3) to a range of 0.774 to 1.23 mg/m(3); and inhalable dust concentration from 47.2 mg/m(3) to a range of 2.13 to 6.09 mg/m(3). Silica concentrations were reduced from 0.308 mg/m(3) to a range of 0.006 to 0.028 mg/m(3) in the respirable size fraction, from 0.821 mg/m(3) to a range of 0.043 to 0.090 mg/m(3) in the thoracic size fraction, and from 2.71 mg/m(3) to a range of 0.124 to 0.403 mg/m(3) in the inhalable size fraction. Reductions in dust concentrations while using the four LEV systems were not statistically significantly different from each other.

    2011-01-01

    Current business leaders continue to adopt e-learning technology despite concerns regarding its value. Positing that the effectiveness of e-training depends on how its environment is managed, we argue that a learner-centric approach is necessary in order to achieve workplace training goals. We subsequently develop a theoretical model that is aimed at identifying the key components of learner-centered e-training environments, which serve the function of providing a benchmarked approach for evaluating e-training success. The model was empirically tested using data from an Internet survey of retail industry employees and partial least squares techniques were used for analysis. Based on the findings, this study clarifies what is needed for successful e-training in terms of instructional design, system design, and organizational support.

    2012-11-01

    To compare the obesity related training, practices, and perceptions of home child care providers and center care providers. A self-administered survey was collected from child care providers who attended local child care training workshops in east central Illinois from March 2009 to August 2010. Study results were based on responses from 88 home care providers and 94 center providers. The survey questions addressed child care providers' training in the prior year, their obesity prevention practices including written policies, their perceptions of influences on children's health, and factors determining food menu selection. Paired t tests and Chi-square tests were used to compare the difference by child care type. 81.9% of home care providers and 58.6% of center care providers received nutrition training, while 66.7 and 43.0% of these providers received physical activity training, respectively. Nutrition content, guidelines or state regulations, and food availability were the most important factors that influenced both types of care providers' food service menus. Both care provider types perceived they have less influence on children's food preferences, eating habits, and weight status compared to the home environment. However, home care providers perceived a smaller discrepancy between the influences of child care and home environments compared to center care providers. Compared to center providers, home care providers were more likely to have had training, be involved with health promotion activities, and rate their influence higher on children's health behaviors. Findings underscore the need for obesity prevention efforts in both types of child care settings.

    The evaluation of primary healthcare services provided by health training centers of a private medical college has not been studied in comparison with government health facilities in Indian context. Data envelopment analysis (DEA) is one such technique of operations research, which can be used on health facilities for identifying efficient operating practices and strategies for relatively efficient or inefficient health centers by calculating their efficiency scores. This study was carried out by DEA technique by using basic radial models (constant ratio to scale (CRS)) in linear programming via DEAOS free online Software among four decision making units (DMUs; by comparing efficiency of two private health centers of a private medical college of India with two public health centers) in district Muzaffarnagar of state Uttar Pradesh. The input and output records of all these health facilities (two from private and two from Government); for 6 months duration from 1(st) Jan 2014 to 1(st) July 2014 was taken for deciding their efficiency scores. The efficiency scores of primary healthcare services in presence of doctors (100 vs 30%) and presence of health staff (100 vs 92%) were significantly better from government health facilities as compared to private health facilities (P healthcare services delivery by DEA technique reveals that the government health facilities group were more efficient in delivery of primary healthcare services as compared to private training health facilities group, which can be further clarified in by more in-depth studies in future.

    1994-02-01

    This report summarizes and discusses the results obtained during 1992 from the study of long-billed curlews on the Yakima Training Center (YTC), which Pacific Northwest Laboratory conducted for the US Department of the Army. This study was initiated to provide basic ecological information on YTC long-billed curlews (Numenius americanus). The long-billed curlew is a relatively common spring and summer resident on the YTC. However, other than casual observations, very little is known about the distribution, density, reproductive success, and habitat requirements for this species on the YTC. Until recently the long-billed curlew was a US Fish and Wildlife Service candidate for listing as threatened or endangered; however, on November 21, 1991 it was down-listed to Class IIIc. The Washington Department of Wildlife lists the long-billed curlew as a ``species of special concern.`` Specific objectives of this study were to (1) locate nesting areas, (2) locate brood-rearing areas, (3) evaluate habitat requirements, (4) determine diet, (5) evaluate response to troop activities, (6) evaluate the impact of livestock grazing, (7) estimate the population size, and (8) estimate recruitment rates. Six curlews (four females and two males) were captured and fitted with radio transmitters. These birds were relocated to obtain nesting, habitat use, and feeding information. Road surveys conducted over most of the YTC provided information on the bird`s general distribution, habitat requirements, and nesting and brood-rearing areas.

    AIM: To determine the incidence of colonoscopic perforation (CP), and evaluate clinical findings, management and outcomes of patients with CP from the World Gastroenterology Organization (WGO) Endoscopy Training Center in Thailand. METHODS: All colonoscopies and sigmoidoscopies performed between 1999 and 2007 in the Endoscopic unit, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok were reviewed. Incidence of CP, patients’ characteristics, endoscopic information, intra-operative findings, management and outcomes were analyzed. RESULTS: A total of 17 357 endoscopic procedures of the colon (13 699 colonoscopies and 3658 flexible sigmoidoscopies) were performed in Siriraj hospital over a 9-year period. Fifteen patients (0.09%) had CP: 14 from colonoscopy and 1 from sigmoidoscopy. The most common site of perforation was in the sigmoid colon (80%), followed by the transverse colon (13%). Perforations were caused by direct trauma from either the shaft or the tip of the endoscope (n = 12, 80%) and endoscopic polypectomy (n = 3, 20%). All patients with CP underwent surgical management: primary repair (27%) and bowel resection (73%). The mortality rate was 13% and postoperative complication rate was 53%. CONCLUSION: CP is a rare but serious complication following colonoscopy and sigmoidoscopy, with high rates of morbidity and mortality. Incidence of CP was 0.09%. Surgery is still the mainstay of CP management. PMID:19034978

    Ulnar artery thrombosis and hypothenar hammer syndrome are rare vascular complications that could potentially occur with repeated blows or trauma to the hand. Although initially reported as an occupational hazard among laborers and craftsmen, it has been observed more recently among recreationalists and athletes. Until now, it has never been reported as a complication in ice hockey players. In this case report, a 26-year-old Canadian professional ice hockey player presented with acute dominant right hand paleness, coolness, and pain with hand use. The patient used a wooden hockey stick with a large knob of tape at the end of the handle, which he regularly gripped in the palm of his right hand to help with face-offs and general stick-handling. Sonographic evaluation demonstrated no arterial flow in the distal right ulnar artery distribution, and ulnar artery occlusion with no aneurysmal degeneration was confirmed by magnetic resonance angiogram. Intraarterial thrombolytic therapy was initiated, and subsequent serial angiograms demonstrated significant improvement in distal ulnar artery flow as well as recanalization of right hand deep palmar arch and digital arteries. The patient's symptoms resolved, and he was maintained on therapeutic anticoagulation for 3 months prior to returning to playing ice hockey professionally, but with a padded glove and no tape knob at the handle tip. This case highlights a unique presentation of hockey stick-handling causing ulnar artery thrombosis that was likely from repeated palmar hypothenar trauma. Appropriate diagnostic imaging, early intraarterial thrombolysis, and postoperative surveillance and follow-up were crucial for the successful outcome in this patient. Copyright © 2013 Elsevier Inc.

    Extracorporeal membrane oxygenation (ECMO) requires a multidisciplinary healthcare team. The Extracorporeal Life Support Organization publishes training guidelines but leaves specific requirements up to each institution. Simulation training has shown promise, but it is unclear how many institutions have incorporated simulation techniques into ECMO training to date. We sent an electronic survey to ECMO coordinators at Extracorporeal Life Support Organization sites in the United States. Participants were asked about training practices and the use of simulation for ECMO training. Descriptive results were reported as the percentage of total responses for each question. Logistic regression was used to identify characteristics associated with simulation use. Of 94 responses (62% response rate), 46% had an ECMO simulation program, whereas 26% report a program is in development. Most (61%) have been in operation for 2 to 5 years. Sixty-three percent use simulation for summative assessment, and 76% have multidisciplinary training. Access to a simulation center [odds ratio (OR) = 4.7, 95% confidence interval (CI) = 1.7-12.5], annual ECMO caseload of greater than 20 (OR = 2.5, 95% CI = 1.5-5.8), and having a pediatric cardiothoracic intensive care unit (OR = 2.8, 95% CI = 1.2-6.7) are each associated with increased likelihood of mannequin-based ECMO simulation. Common scenarios include pump failure (93%), oxygenator failure (90%), and circuit rupture (76%). Extracorporeal membrane oxygenation simulation is growing but remains in its infancy. Centers with access to a simulation center, higher caseloads, and pediatric cardiothoracic intensive care units are more likely to have ECMO simulation programs. Extracorporeal membrane oxygenation simulation is felt to be beneficial, and further work is needed to delineate best training practices for ECMO providers.

  15. Understanding the effect of hammering process on the vibration characteristics of cymbals

    Cymbals are thin domed plates used as percussion instruments. When cymbals are struck, they vibrate and radiate sound. Cymbals are made through spin forming, hammering, and lathing. The spin forming creates the basic shape of the cymbal, which determines its basic vibration characteristics. The hammering and lathing produce specific sound adjustments by changing the cymbal's vibration characteristics. In this study, we study how hammering cymbals affects their vibration characteristics. The hammering produces plastic deformation (small, shallow dents) on the cymbal's surface, generating residual stresses throughout it. These residual stresses change the vibration characteristics. We perform finite element analysis of a cymbal to obtain its stress distribution and the resulting change in vibration characteristics. To reproduce the stress distribution, we use thermal stress analysis, and then with this stress distribution we perform vibration analysis. These results show that each of the cymbal's modes has a different sensitivity to the thermal load (i.e., hammering). This difference causes changes in the frequency response and the deflection shape that significantly improves the sound radiation efficiency. In addition, we explain the changes in natural frequencies by the stress and modal strain energy distributions.

    Excellence and quality models are comprehensive methods for improving the quality of healthcare. The aim of this study was to design excellence and quality model for training centers of primary health care using Delphi method. In this study, Delphi method was used. First, comprehensive information were collected using literature review. In extracted references, 39 models were identified from 34 countries and related sub-criteria and standards were extracted from 34 models (from primary 39 models). Then primary pattern including 8 criteria, 55 sub-criteria, and 236 standards was developed as a Delphi questionnaire and evaluated in four stages by 9 specialists of health care system in Tabriz and 50 specialists from all around the country. Designed primary model (8 criteria, 55 sub-criteria, and 236 standards) were concluded with 8 criteria, 45 sub-criteria, and 192 standards after 4 stages of evaluations by specialists. Major criteria of the model are leadership, strategic and operational planning, resource management, information analysis, human resources management, process management, costumer results, and functional results, where the top score was assigned as 1000 by specialists. Functional results had the maximum score of 195 whereas planning had the minimum score of 60. Furthermore the most and the least sub-criteria was for leadership with 10 sub-criteria and strategic planning with 3 sub-criteria, respectively. The model that introduced in this research has been designed following 34 reference models of the world. This model could provide a proper frame for managers of health system in improving quality.

    1994-10-01

    Geophysical exploration was conducted in the Lautertal at the Combat Maneuver Training Center, Hohenfels, Germany, to determine the shallow geological framework of a typical dry valley in this karstic environment. The complementary methods of electromagnetic surveying, vertical electrical soundings, and seismic refraction profiling were successful in determining the depth and configuration of the bedrock surface, the character of the unconsolidated deposits resting on the bedrock surface, and the nature of the bedrock surface. Channels and other depressions in the bedrock surface are aligned with structurally induced fractures in the bedrock. The unconsolidated deposits consist of coarse alluvium and colluvium, which are confined to these channels and other depressions, and fine-grained loam and loess, which cover most of the Lautertal. Wide ranges in the electrical and elastic parameters of the bedrock surface are indicative of carbonate rock that is highly fractured and dissolved at some locations and competent at others. Most local groundwater recharge occurs in the uplands where the Middle Kimmeridge (Delta) Member of the Maim Formation (Jurassic) is widely exposed. These carbonate rocks are known to be susceptible to dissolution along the fractures and joints; thus, they offer meteoric waters ready access to the main shallow aquifers lower in the Malm Formation. These same rocks also form the bedrock surface below many of the dry valleys, but in the Lautertal, the infiltration of meteoric waters into the subsurface is generally impeded by the surficial layer of fine-grained loam and loess, which have low hydraulic conductivity. Further, the rocks of the Middle Kimmeridge Member appear to be closely associated with the localized occurrence of turbidity in such perennial streams as the Lauterach.

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Alaska Army National Guard property known as Camp Carroll Training Center, located on the Fort Richardson Army facility near Anchorage, Alaska. Preliminary assessments of federal facilities are being conducted to compile the information necessary for the completion of preremedial activities and to provide a basis for establishing, corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, types and quantities of hazardous substances used, the nature and amounts of wastes generated or stored at the facility, and potential pathways by which contamination could affect public health and the environment. The primary environmentally significant operations (ESOs) associated with the property are (1) the Alaska Air National Guard storage area behind Building S57112 (Organizational Maintenance Shop [OMS] 6); (2) the state of Alaska maintenance facility and the soil/tar-type spill north of the state of Alaska maintenance facility; (3) the waste storage area adjacent to OMS 6; (4) the contaminated area from leaking underground storage tanks (USTs) and the oil-water separator; and (5) soil staining in the parking area at the Camp Carroll Headquarters Building. Camp Carroll appears to be in excellent condition from an environmental standpoint, and current practices are satisfactory. Argonne recommends that the Alaska Department of Military Affairs consider remediation of soil contamination associated with all storage areas, as well as reviewing the practices of other residents of the facility. Argonne also recommends that the current methods of storing waste material behind Building S57112 (OMS 6) be reviewed for alternatives.

  19. IMPACT OF ROCK HARDNESS ON FRAGMENTATION BY HYDRAULIC HAMMER AND CRUSHING IN JAW CRUSHER

    Directory of Open Access Journals (Sweden)

    Trpimir Kujundžić

    2008-12-01

    Full Text Available The physical and mechanical characteristics of intact rocks depend on the way of their formation, sustained deformations and the process of wearing a specific rock has been exposed to. These characteristics have a rather high influence on the technological process of extraction and dressing of mineral raw materials. However, the mechanical characteristics of rocks due to use of explosives for their extraction in the open pit have a more significant impact. The rock blocks extracted by blasting which are larger than the opening of the primary crusher are usually fragmented by hydraulic hammer. The paper presents the results of the testing of impact of rock hardness on fragmentation of rocks by means of hydraulic hammer and during crushing in jaw crusher. The testing was carried out on the rock samples from five quarries. According to the obtained results the hardness has a considerably larger impact on the fragmentation energy by hydraulic hammer than on the crushing energy in jaw crusher.

    This innovation comprises a compact drill that uses low-axial preload, via vibrations, that fractures the rock under the bit kerf, and rotates the bit to remove the powdered cuttings while augmenting the rock fracture via shear forces. The vibrations fluidize the powered cuttings inside the flutes around the bit, reducing the friction with the auger surface. These combined actions reduce the consumed power and the heating of the drilled medium, helping to preserve the pristine content of the produced samples. The drill consists of an actuator that simultaneously impacts and rotates the bit by applying force and torque via a single piezoelectric stack actuator without the need for a gearbox or lever mechanism. This reduces the development/fabrication cost and complexity. The piezoelectric actuator impacts the surface and generates shear forces, fragmenting the drilled medium directly under the bit kerf by exceeding the tensile and/or shear strength of the struck surface. The percussive impact action of the actuator leads to penetration of the medium by producing a zone of finely crushed rock directly underneath the struck location. This fracturing process is highly enhanced by the shear forces from the rotation and twisting action. To remove the formed cuttings, the bit is constructed with an auger on its internal or external surface. One of the problems with pure hammering is that, as the teeth become embedded in the sample, the drilling efficiency drops unless the teeth are moved away from the specific footprint location. By rotating the teeth, they are moved to areas that were not fragmented, and thus the rock fracturing is enhanced via shear forces. The shear motion creates ripping or chiseling action to produce larger fragments to increase the drilling efficiency, and to reduce the required power. The actuator of the drill consists of a piezoelectric stack that vibrates the horn. The stack is compressed by a bolt between the backing and the horn in order to

    A percussive augmenter bit includes a connection shaft for mounting the bit onto a rotary drill. In a first modality, an actuator percussively drives the bit, and an electric slip-ring provides power to the actuator while being rotated by the drill. Hammering action from the actuator and rotation from the drill are applied directly to material being drilled. In a second modality, a percussive augmenter includes an actuator that operates as a hammering mechanism that drives a free mass into the bit creating stress pulses that fracture material that is in contact with the bit.

    How can physicians incorporate the electronic health record (EHR) into clinical practice in a relationship-enhancing fashion ("EHR ergonomics")? Three convenience samples of 40 second-year medical students with varying levels of EHR ergonomic training were compared in the 2012 spring semester. All participants first received basic EHR training and completed a presurvey. Two study groups were then instructed to use the EHR during the standardized patient (SP) encounter in each of four regularly scheduled Doctoring (clinical skills) course sessions. One group received additional ergonomic training in each session. Ergonomic assessment data were collected from students, faculty, and SPs in each session. A postsurvey was administered to all students, and data were compared across all three groups to assess the impact of EHR use and ergonomic training. There was a significant positive effect of EHR ergonomics skills training on students' relationship-centered EHR use (Pergonomic training sessions were needed to see an overall improvement in EHR use. In addition to replication of these results, further effectiveness studies of this educational intervention need to be carried out in GME, practice, and other environments.

    Background Cognitive care for the most prevalent neurologic and psychiatric conditions will only improve through the implementation of new sustainable approaches. Innovative cognitive training methodologies and collaborative professional networks are necessary evolutions in the mental health sector. Objective The objective of the study was to describe the implementation process and early outcomes of a nationwide multi-organizational network supported on a Web-based cognitive training system (COGWEB). Methods The setting for network implementation was the Portuguese mental health system and the hospital-, academic-, community-based institutions and professionals providing cognitive training. The network started in August 2012, with 16 centers, and was monitored until September 2013 (inclusions were open). After onsite training, all were allowed to use COGWEB in their clinical or research activities. For supervision and maintenance were implemented newsletters, questionnaires, visits and webinars. The following outcomes were prospectively measured: (1) number, (2) type, (3) time to start, and (4) activity state of centers; age, gender, level of education, and medical diagnosis of patients enrolled. Results The network included 68 professionals from 41 centers, (33/41) 80% clinical, (8/41) 19% nonclinical. A total of 298 patients received cognitive training; 45.3% (n=135) female, mean age 54.4 years (SD 18.7), mean educational level 9.8 years (SD 4.8). The number enrolled each month increased significantly (r=0.6; P=.031). At 12 months, 205 remained on treatment. The major causes of cognitive impairment were: (1) neurodegenerative (115/298, 38.6%), (2) structural brain lesions (63/298, 21.1%), (3) autoimmune (40/298, 13.4%), (4) schizophrenia (30/298, 10.1%), and (5) others (50/298, 16.8%). The comparison of the patient profiles, promoter versus all other clinical centers, showed significant increases in the diversity of causes and spectrums of ages and education

    Full Text Available Water hammer analysis is a fundamental work of pipeline systems design process for water distribution networks. The main characteristics for mine drainage system are the limited space and high cost of equipment and pipeline changing. In order to solve the protection problem of valve-closing water hammer for mine drainage system, a water hammer protection method for mine drainage system based on velocity adjustment of HCV (Hydraulic Control Valve is proposed in this paper. The mathematic model of water hammer fluctuations is established based on the characteristic line method. Then, boundary conditions of water hammer controlling for mine drainage system are determined and its simplex model is established. The optimization adjustment strategy is solved from the mathematic model of multistage valve-closing. Taking a mine drainage system as an example, compared results between simulations and experiments show that the proposed method and the optimized valve-closing strategy are effective.

    Full Text Available The objective of this study is to identify the role and training of occupational therapists in the Support Center for Family Health (NASF in Recife, Pernambuco state. It is an exploratory research of quantitative approach performed with ten occupational therapists in 2011; data was obtained by self-administered questionnaires. According to the interviewees, the role of the occupational therapist is to offer holistic attention focused on functional performance, prevention of incapacities, rehabilitation, and social inclusion. Matrix support is the most common type of support provided by occupational therapists and Family Health teams to the monitored cases. The most commonly used places in these interventions are the homes of patients and the Family Health Center. The small effectiveness of public policies was mentioned as the greatest difficulty. In spite of the general character of the vocational training provided, it was considered insufficient for the NASF by 70% of the interviewees. The need for themes such as primary health care and health programs and policies was highlighted by those who wanted to be trained. We conclude that the role of the occupational therapist in the NASF is based on specific attributions in functional development and prevention of incapacities. The core of the profession, holistic health care, and social inclusion are considered attributions in common with those of primary health care workers. Vocational training as preparation for working in the NASF was considered insufficient by the interviewees, once it is a new area for professional acting and updating.

    There is no standardized or formal communication skills training in the current nursing curriculum in Macao, China. To develop and evaluate a learner-centered communication skills training course. Both qualitative and quantitative designs were used in two separate stages. A randomized sample and a convenience sample were taken from students on a four-year bachelor's degree program at a public institute in Macao. Stage I consisted of developing a learner-centered communication skills training course using four focus groups (n=32). Stage II evaluated the training's efficacy by comparing communication skills, clinical interaction, interpersonal dysfunction, and social problem-solving abilities using a quasi-experimental longitudinal pre-post design among 62 nursing students. A course evaluation form was also used. Content analysis was used to evaluate the essential themes in order to develop the specific content and teaching strategies of the course. Paired t-tests and Wilcoxon signed-rank tests showed significant improvement in all post-training scores for communication ability, content of communication, and handling of communication barriers. According to the mean scores of the course evaluation form, students were generally very satisfied with the course: 6.11 to 6.74 on a scale of 1 to 7. This study showed that the course was effective in improving communication skills, especially in terms of the content and the handling of communication barriers. The course filled an important gap in the training needs of nursing students in Macao. The importance of these findings and their implications for nursing education are discussed.

    Maintaining a sufficient and competent rural nursing workforce is important in Chinese health delivery system. However, few studies have involved in the health training status and needs assessment of rural Chinese nurses in great transformations of health policy. This study is to explore the current health training status and to ascertain needs perceived by nurses working in rural Chinese township health centers (THCs). A cross-sectional survey using a self-administered structured questionnaire was conducted to 240 THC nurses in Guangxi Zhuang Autonomous region, China from March 2014 to August 2014. Survey questionnaire was adopted from the Second Chinese Survey of Demographic Data and Training Demand for Health Professionals in THCs by the Ministry of Education. The nurses in THCs were young with low educational background. The perceived needs in health training included further clinical study in city level hospitals to improve skills and theory study in medical universities in emergency medicine and general practice. There are 71.9% of the nurses with secondary technical school background and 68.5% of nurses with junior college education expected to take junior college or bachelor degree study, respectively. A decentralized program with theory study in medical universities and practice study in county hospitals were regarded as feasible by 66.9% of total respondents. There is a need to improve health-training programs for nurses in Chinese township health centers in coverage, delivery mode, and contents. A decentralized degree-linked training program collaborated with medical universities and city hospitals would be an appropriate mode.

    Functional urinary incontinence causes considerable morbidity in 8.4% of school-age children, mainly girls. To compare oxybutynin, placebo, and bladder training in overactive bladder (OAB), and cognitive treatment and pelvic floor training in dysfunctional voiding (DV), a multi-center controlled trial was designed, the European Bladder Dysfunction Study. Seventy girls and 27 boys with clinically diagnosed OAB and urge incontinence were randomly allocated to placebo, oxybutynin, or bladder training (branch I), and 89 girls and 16 boys with clinically diagnosed DV to either cognitive treatment or pelvic floor training (branch II). All children received standardized cognitive treatment, to which these interventions were added. The main outcome variable was daytime incontinence with/without urinary tract infections. Urodynamic studies were performed before and after treatment. In branch I, the 15% full response evolved to cure rates of 39% for placebo, 43% for oxybutynin, and 44% for bladder training. In branch II, the 25% full response evolved to cure rates of 52% for controls and 49% for pelvic floor training. Before treatment, detrusor overactivity (OAB) or pelvic floor overactivity (DV) did not correlate with the clinical diagnosis. After treatment these urodynamic patterns occurred de novo in at least 20%. The mismatch between urodynamic patterns and clinical symptoms explains why cognitive treatment was the key to success, not the added interventions. Unpredictable changes in urodynamic patterns over time, the response to cognitive treatment, and the gender-specific prevalence suggest social stress might be a cause for the symptoms, mediated by corticotropin-releasing factor signaling pathways. © 2013 Wiley Periodicals, Inc.

    In response to environmental concerns at the Combat Maneuver Training Center (CMTC), Hohenfels, Germany, the US Army 7th Army Training Command commissioned a scientific study by Argonne National Laboratory to investigate specific issues. The study involved three parts: (1) a field study to determine if fog oil and CS (a compound named after its discoverers, B.B. Carson and R.W. Stoughton) were accumulating in the CMTC environment, (2) a screening of selected soil samples for the presence of US Environmental Protection Agency priority pollutants, and (3) a literature review of the health effects of fog oil and CS, as well as a review of training practices at CMTC. No fog oil or fog oil degradation products were detected in any soil, sediment, or vegetation sample collected at CMTC. Trace quantities of one or more priority pollutants were tentatively detected in three of eight soil and sediment samples. However, the priority pollutant concentrations are so low that they pose no environmental or health hazards. No evidence of widespread or significant contamination in the training areas was found. Crucial data needed to fully evaluate both acute and chronic health effects of civilian exposures to CS at CMTC are not available. On the basis of the available literature, long-ten-n health effects in the civilian population near CMTC that could result from the use of fog oil and CS during training activities are believed to be negligible.

    The paucity of neurosurgical care in East Africa remains largely unaddressed. A sustained investment in local health infrastructures and staff training is needed to create an independent surgical capacity. The Madaktari organization has addressed this issue by starting initiatives to train local general surgeons and assistant medical officers in basic neurosurgical procedures. We report illustrative cases since beginning of the program in Mwanza in 2009 and focus on the most recent training period. A multi-institutional neurosurgical training program and a surgical database was created at a tertiary referral center in Mwanza, Tanzania. We collected clinical data on consecutive patients who underwent a neurosurgical procedure between September 9th and December 1st, 2011. All procedures were performed by a local surgeon under the supervision of a visiting neurosurgeon. Since the inception of the training initiative, comprehensive multidisciplinary training courses in Tanzania and an annual visiting fellowship for East African surgeons to travel to a major U.S. medical center have been established. At initial visits infrastructure and feasibility of complex case scenarios was assessed. Surgeries for brain tumors and complex spinal cases were performed. During the 3-month training period, 62 patients underwent surgery. Pediatric hydrocephalus comprised 52% of patients, 11% suffered from meningomyelocelia, and 6% presented with an encephalocele. A total of 24% of patients were treated for trauma-related conditions, representing 75% of the adult patients. A total of 10% of patients had surgery because of traumatic spine injury, and 15% of operations were on patients with severe head injury. A total of 6% of patients presented with degenerative spine disease. One patient sustained a fatal perioperative complication. At the end of the training period, the local general surgeon was able to perform all basic neurosurgical cases independently. Neurosurgical care in Tanzania

    This workshop demonstrated the utility of a patient-centered web-based/digital Breaking Bad News communication training module designed to educate learners of various levels and disciplines. This training module is designed for independent, self-directed learning as well as group instruction. These interactive educational interventions are based upon video-recorded patient stories. Curriculum development was the result of an interdisciplinary, collaborative effort involving faculty from the East Tennessee State University (ETSU) Graduate Storytelling Program and the departments of Family and Internal Medicine at the James H. Quillen College of Medicine. The specific goals of the BBN training module are to assist learners in: (1) understanding a five-step patient-centered model that is based upon needs, preferences, and expectations of patients with cancer and (2) individualizing communication that is consistent with patient preferences in discussing emotions, informational detail, prognosis and timeline, and whether or not to discuss end-of-life issues. The pedagogical approach to the training module is to cycle through Emotional Engagement, Data, Modeled Practices, Adaptation Opportunities, and Feedback. The communication skills addressed are rooted in concepts found within the Reaching Common Ground communication training. A randomized control study investigating the effectiveness of the Breaking Bad News module found that medical students as well as resident physicians improved their communication skills as measured by an Objective Structured Clinical Examination. Four other similarly designed modules were also created: Living Through Treatment, Transitions: From Curable to Treatable/From Treatable to End-of-Life, Spirituality, and Family. © The Author(s) 2016.

    Full Text Available We analyzed the manufacturing procedure, specifications, repair history, and details of celestial movements of the water-hammering type Honsang (celestial globe. Results from our study on the remaining Honsangs in China and Japan and on the reconstruction models in Korea were applied to our conceptual design of the water-hammering type Honsang. A Honui (armillary sphere and Honsang using the water-hammering method were manufactured in Joseon in 1435 (the 17th year of King Sejong. Jang Yeong-Sil developed the Honsang system based on the water-operation method of Shui yün i hsiang t’ai in China. Water-operation means driving water wheels using a water flow. The most important factor in this type of operation is the precision of the water clock and the control of the water wheel movement. The water-hammering type Honsang in Joseon probably adopted the Cheonhyeong (天衡; oriental escapement device system of Shui yün i hsiang t’ai in China and the overflow mechanism of Jagyeongnu (striking clepsydra in Joseon, etc. In addition to the Cheonryun system, more gear instruments were needed to stage the rotation of the Honsang globe and the sun’s movement. In this study, the water-hammering mechanism is analyzed in the structure of a water clock, a water wheel, the Cheonhyeong system, and the Giryun system, as an organically working operation mechanism. We expect that this study will serve as an essential basis for studies on Heumgyeonggaknu, the water-operating astronomical clock, and other astronomical clocks in the middle and latter parts of the Joseon dynasty.

    Developing technologies that would enable future NASA exploration missions to penetrate deeper into the subsurface of planetary bodies for sample collection is of great importance. Performing these tasks while using minimal mass/volume systems and with low energy consumption is another set of requirements imposed on such technologies. A deep drill, called Auto-Gopher II, is currently being developed as a joint effort between JPL's NDEAA laboratory and Honeybee Robotics Corp. The Auto-Gopher II is a wireline rotary-hammer drill that combines formation breaking by hammering using an ultrasonic actuator and cuttings removal by rotating a fluted auger bit. The hammering mechanism is based on the Ultrasonic/Sonic Drill/Corer (USDC) mechanism that has been developed as an adaptable tool for many drilling and coring applications. The USDC uses an intermediate free-flying mass to transform high frequency vibrations of a piezoelectric transducer horn tip into sonic hammering of the drill bit. The USDC concept was used in a previous task to develop an Ultrasonic/Sonic Ice Gopher and then integrated into a rotary hammer device to develop the Auto-Gopher-I. The lessons learned from these developments are being integrated into the development of the Auto- Gopher-II, an autonomous deep wireline drill with integrated cuttings and sample management and drive electronics. Subsystems of the wireline drill are being developed in parallel at JPL and Honeybee Robotics Ltd. This paper presents the development efforts of the piezoelectric actuator, cuttings removal and retention flutes and drive electronics.

    This article introduces the systems-centered concept of the "group mind" by linking systems-centered thinking and interpersonal neurobiology, building on Siegel's definition of mind as the process of regulating the flow of energy and information. Functional subgrouping, the systems-centered group method for resolving conflicts, discriminates and integrates the flow of energy and information within and between group members, subgroups, and the group-as-a-whole, thus potentiating survival, development, and transformation. This article uses the interpersonal neurobiological framework to discuss functional subgrouping as a tool for developing the group mind: considering how functional subgrouping facilitates emotional regulation, creates a secure relational context, and potentiates neural integration.

    Excess weight gain is common when adolescents become young adults, but there are no obesity prevention or weight management interventions that have been tested for emerging adults who follow non-traditional post-secondary paths, such as enrolling in job training programs. We evaluated Healthy Eating & Active Lifestyles (HEALs), a policy-mandated lifestyle education/environmental modification program, at a job training center for low-income 16-24 year olds. We examined average change in body mass index (BMI) z-score from baseline to 6 months for emerging adults (aged 16-24 years) in pre-HEALs implementation (n = 125) and post-HEALs implementation (n = 126) cohorts living at the job training center, by baseline weight status. In both cohorts, average BMI z-score significantly increased from baseline to 6 months for students with BMI < 25. Average BMI z-score significantly decreased for the overweight (BMI 25 to <30; -0.11, p = .03) and obese (BMI ≥ 30; -0.11, p = .001) students only within the post-HEALs cohort; changes within the pre-HEALs cohort and between cohorts were not significant. HEALs may promote positive weight-related trends for overweight/obese students, but prevention efforts for non-overweight/obese students need to be improved.

    In 2013, the Harvard Medical School Center for Primary Care established the Abundance Agents of Change (AoC) program to promote interprofessional learning and innovation, increase partnership between 15 academic and community health centers (CHCs) in Boston's most under-served communities, and increase medical student interest in primary care careers. The AoC is modeled in the form of a 'grants challenge', offering $20,000 to interprofessional student teams to develop an innovative solution that addresses a healthcare delivery need identified by CHCs. The program's initial two years were characterized by a four-stage process which included working with CHCs and crafting a request for proposals, forming interprofessional 20 student teams comprising students from across and outside of Harvard University, training students using a systems-based innovation curriculum, and performing program evaluation. Our evaluation data from cohorts 1 and 2 of the AoC program demonstrate that we succeeded in training students as innovators and members of interprofessional teams. We also learned valuable lessons regarding creating better alignment with CHC priorities, extending the program cycle from 12 to 18 months, and changing the way funding is disbursed to 25 students, which will be incorporated in later versions of the program. Based on our experience and evaluation data, we believe that this program is a replicable way to train students as innovators and members of interprofessional teams to address the current complex healthcare environment.

    2017-09-01

    In order to separate aluminum from the base-cap of spent fluorescent lamp (SFL), the separation efficiency of hammer crusher unit is estimated by introducing a binary separation theory. The base-cap of SFL is composed by glass fragment, binder, ferrous metal, copper and aluminum. The hammer crusher unit to recover aluminum from the base-cap consists of 3stages of hammer crusher, magnetic separator and vibrating screen. The optimal conditions of rotating speed and operating time in the hammer crusher unit are decided at each stage. At the optimal conditions, the aluminum yield and the separation efficiency of hammer crusher unit are estimated by applying a sequential binary separation theory at each stage. And the separation efficiency between hammer crusher unit and roll crush system is compared to show the performance of aluminum recovery from the base-cap of SFL. Since the separation efficiency can be increased to 99% at stage 3, from the experimental results, it is found that aluminum from the base-cap can be sufficiently recovered by the hammer crusher unit.

    2015-12-01

    The Center for the Study of Active Volcanoes, in cooperation with the USGS Volcano Hazards Program at HVO and CVO, offers a broadly based volcano hazards training program targeted toward scientists and technicians from developing nations. The program has been offered for 25 years and provides a hands-on introduction to a broad suite of volcano monitoring techniques, rather than detailed training with just one. The course content has evolved over the life of the program as the needs of the trainees have changed: initially emphasizing very basic monitoring techniques (e.g. precise leveling, interpretation of seismic drum records, etc.) but, as the level of sophistication of the trainees has increased, training in more advanced technologies has been added. Currently, topics of primary emphasis have included volcano seismology and seismic networks; acquisition and modeling of geodetic data; methods of analysis and monitoring of gas geochemistry; interpretation of volcanic deposits and landforms; training in LAHARZ, GIS mapping of lahar risks; and response to and management of volcanic crises. The course also provides training on public outreach, based on CSAV's Hawaii-specific hazards outreach programs, and volcano preparedness and interactions with the media during volcanic crises. It is an intensive eight week course with instruction and field activities underway 6 days per week; it is now offered in two locations, Hawaii Island, for six weeks, and the Cascades volcanoes of the Pacific Northwest, for two weeks, to enable trainees to experience field conditions in both basaltic and continental volcanic environments. The survival of the program for more than two decades demonstrates that a need for such training exists and there has been interaction and contribution to the program by the research community, however broader engagement with the latter continues to present challenges. Some of the reasons for this will be discussed.

  18. Comparison of Acoustic Energy Meter (AEM) and Schmidt hammer 'R' for rapid assessment of rock surface hardness: a preliminary assessment from southeast Queensland, Australia

    Brook, Martin; Winkler, Stefan

    2015-04-01

    This research focuses on one of the key challenges in geomorphology - quantifying rock surface hardness via in situ measurements, to provide information on rock physical properties. This has been a focus in recent years with the rapid emergence of studies that center on surface and near surface weathering impacts, and rates of material loss. Indeed, a key element to understanding how weathering and erosion processes combine to influence rock surface (and landscape) evolution is the measurement and monitoring of rock surface hardness. We provide results from a preliminary assessment of the applicability of the Acoustic Energy Meter (AEM) to subaerial rock surface hardness, in comparison with an N-Type Schmidt hammer. The AEM apparatus consists of a geophone which is in contact with the rock surface and some electronics. The AEM is held normal to the surface to be tested and the surface is struck with a small hammer (typically 0.75 kg), with the AEM quantifying the decay time of seismically-induced oscillations within the top c. 1-2 m of the rock mass. Previous work using an AEM has focused on measuring roof stability and delamination in South African underground coal, gold and platinum mines, where long AEM reverberation times correlated well with weak rock mass and dense microfracturing. However, the technique has rarely been applied to the assessment of rock surfaces in a subaerial setting. We applied the technique to a range of lithologies at five sites in southeast Queensland in the Brisbane area, each an exposure of phyllite, granite, mudstone, argillite or volcanic tuff. The aims were: (1) quantifying the response of different rock masses to the AEM technique; and (2) assessing the applicability of the AEM as a rapid in situ measure of rock hardness by comparing results with Schmidt hammer 'R' values from the same exposures. Results showed that the AEM is useful in discriminating rock hardness across rocks with different lithological properties. Second, an

    Practical operative training in the discipline of visceral surgery is currently under discussion. Aside from surveys, data on this topic in Germany are sparse. The aim of the study was an objective collation of surgical residents' practical training in the operating room in our department. All surgical cases from 2015 were prospectively included. Procedures were stratified into resident and non-resident operations and complex cases with sub-steps which could potentially be performed by residents. We analyzed whether an operation or surgical sub-steps were performed by a resident. If this was not achieved, the reasons were analyzed. An anonymous online survey was conducted among employees in the surgery department regarding surgical training. Out of 2896 surgical cases 1141 (39.4 %) were classified as potential resident training operations, which were actually performed by a resident in 743 cases (65.1 %). The survey showed an underestimation of this proportion, where sub-steps were assisted in 30.3 % (n = 265) of 876 potential cases. This proportion significantly increased during the observation period (p < 0.001); however, it was highly overestimated by residents as well as fellows and senior consultants. Often organizational reasons were responsible when resident operations or sub-steps were not performed by a trainee (13.1 % and 30.0 %, respectively). The monocentric analysis per se resulted in an improvement in practical surgical training. In the training environment, assisting with sub-steps provides a great potential. Multicenter studies are needed.

    Community-academic partnerships in the training of doctors offer unique learning opportunities of great importance. Such partnerships can induce a paradigm shift such that physicians view community as a teaching resource and partner rather than as a passive recipient of services or solely as a placement site. The authors describe a model of a community-academic partnership in New York City, begun in 1995, in which, for training and service, pediatric residents are integrally involved in a community-based program. Principles adapted from the Community-Campus Partnerships for Health's principles of partnership provide a framework for portraying the essential elements of developing and maintaining the partnership. The authors explain the clashes that may arise between partners and show how the principles of partnership guide partnership members in working and learning within a setting that by its nature entails conflict and inequality. This report is based on the knowledge gained from the structured reflections of both members of this partnership: the residency program at a large academic health center and the community-based social service organization. Such partnerships provide the training ground for the development of physicians who understand the social and cultural determinants of health and constructively use community agencies' input in promoting child health and well-being. Within this framework, community-based organizations are not solely service providers but become educators of physicians-in-training who, with new knowledge gained through the partnership, more effectively contribute to the overall health of the communities they serve.

    The Centers for Population Health and Health Disparities program promotes multilevel and multifactorial health equity research and the building of research teams that are transdisciplinary. We summarized 5 areas of scientific training for empowering the next generation of health disparities investigators with research methods and skills that are needed to solve disparities and inequalities in cancer and cardiovascular disease. These areas include social epidemiology, multilevel modeling, health care systems or health care delivery, community-based participatory research, and implementation science. We reviewed the acquisition of the skill sets described in the training components; these skill sets will position trainees to become leaders capable of effecting significant change because they provide tools that can be used to address the complexities of issues that promote health disparities.

    Primary care residencies are undergoing dramatic changes because of changing health care systems and evolving demands for updated training models. We examined the relationships between residents' exposures to patient-centered medical home (PCMH) features in their assigned continuity clinics and their satisfaction with training. Longitudinal surveys were collected annually from residents evaluating satisfaction with training using a 5-point Likert-type scale (1=very unsatisfied to 5=very satisfied) from 2007 through 2011, and the presence or absence of PCMH features were collected from 24 continuity clinics during the same time period. Odds ratios on residents' overall satisfaction were compared according to whether they had no exposure to PCMH features, some exposure (1-2 years), or full exposure (all 3 or more years). Fourteen programs and 690 unique residents provided data to this study. Resident satisfaction with training was highest with full exposure for integrated case management compared to no exposure, which occurred in 2010 (OR=2.85, 95% CI=1.40, 5.80). Resident satisfaction was consistently statistically lower with any or full exposure (versus none) to expanded clinic hours in 2007 and 2009 (eg, OR for some exposure in 2009 was 0.31 95% CI=0.19, 0.51, and OR for full exposure 0.28 95% CI=0.16, 0.49). Resident satisfaction for many electronic health record (EHR)-based features tended to be significantly lower with any exposure (some or full) versus no exposure over the study period. For example, the odds ratio for resident satisfaction was significantly lower with any exposure to electronic health records in continuity practice in 2008, 2009, and 2010 (OR for some exposure in 2008 was 0.36; 95% CI=0.19, 0.70, with comparable results in 2009, 2010). Resident satisfaction with training was inconsistently correlated with exposure to features of PCMH. No correlation between PCMH exposure and resident satisfaction was sustained over time.

    2004-01-01

    Full Text Available This paper presents a source/resonator model of hammer-string interaction that produces realistic piano sound. The source is generated using a subtractive signal model. Digital waveguides are used to simulate the propagation of waves in the resonator. This hybrid model allows resynthesis of the vibration measured on an experimental setup. In particular, the nonlinear behavior of the hammer-string interaction is taken into account in the source model and is well reproduced. The behavior of the model parameters (the resonant part and the excitation part is studied with respect to the velocities and the notes played. This model exhibits physically and perceptually related parameters, allowing easy control of the sound produced. This research is an essential step in the design of a complete piano model.

    There is heightened interest in identifying the impact of the federally funded Public Health Training Center (PHTC) program. Although evaluation studies have been conducted of public health training in general, evaluations of PHTC programs are rare. Field placement components are congressionally mandated requirements of PHTCs. Field placements are typically intensive, supervised externships for students to gain public health experience with local health departments or non-profit organizations. We have found no published evaluations of PHTC field placement components. This may be because of their small size and unique nature. We designed and evaluated a 200-h field placement program at an established PHTC. The evaluation included pre/post surveys measuring public health core competencies, and post-experience interviews. We found significant increases in three competency domains among trainees: policy development and program planning, communication skills, and community dimensions of practice. These outcomes contribute to evidence based on the efficacy of PHTC field placement programs, and underscore their role in public health training.

    Diabetes complications can increase progressively, leading to morbidity and mortality among diabetes sufferers. To address this, diabetes self-management education is a strategy to increase patients' knowledge and awareness in self-care. However some issues related to diabetes self-management education have emerged for health care providers and patients. The objective of this project was to improve nurses' skills and confidence in delivering diabetes self-management education among type 2 diabetes patients by promoting evidence based practice in community health centers, thereby enhancing patients' knowledge and skills in performing self-care. The Joanna Briggs Institute three-phase Practical Application of Clinical Evidence System and Getting Research into Practice audit and feedback tool were utilized in this project for promoting evidence utilization and changes in the community health setting. In phase 1 of the project, stakeholders were engaged and 12 evidence-based audit criteria were developed. A baseline audit was conducted by the project team in 41 community health centers. In phase 2, barriers underpinning areas of noncompliance found in the baseline audit were identified and strategies developed to target three key areas - staff, administration and patients. In phase 3, a follow-up audit was conducted. The baseline audit results showed that eight of the 12 criteria recorded zero percent compliance, with the remaining four recording below 50%, representing poor compliance with the current evidence. Strategies implemented during phase 2 of the project included a diabetes educator training program, development of diabetes education curriculum and media, and a patient's logbook. After implementation of the strategies, the follow-up audit showed that all 12 criteria achieved 100% compliance. The diabetes training program for community health center nurses increased their skills and confidence in delivering diabetes self-management education to patients.

    Finger ischemia due to embolic occlusion of digital arteries resulting from trauma to the palmar ulnar artery has been termed hypothenar hammer syndrome (HHS). In HHS, arterial thrombosis and/or aneurysm formation with embolization to the digital arteries causes symptoms of ischemia. We describe a patient in whom the initial diagnosis was made on multidetector computed tomographic angiography (CTA), as well as his endovascular and surgical management.

    The search for present or past life in the Universe is one of the most important objectives of NASA's exploration missions. Drills for subsurface sampling of rocks, ice and permafrost are an essential tool for astrobiology studies on other planets. Increasingly, it is recognized that drilling via a combination of rotation and hammering offers an efficient and effective rapid penetration mechanism. The rotation provides an intrinsic method for removal of cuttings from the borehole while the impact and shear forces aids in the fracturing of the penetrated medium. Conventional drills that use a single actuator are based on a complex mechanism with many parts and their use in future mission involves greater risk of failure and/or may require lubrication that can introduce contamination. In this paper, a compact drill is reported that uses a single piezoelectric actuator to produce hammering and rotation of the bit. A horn with asymmetric grooves was design to impart a longitudinal (hammering) and transverse force (rotation) to a keyed free mass. The drill requires low axial pre-load since the hammering-impacts fracture the rock under the bit kerf and rotate the bit to remove the powdered cuttings while augmenting the rock fracture via shear forces. The vibrations 'fluidize' the powdered cuttings inside the flutes reducing the friction with the auger surface. This action reduces the consumed power and heating of the drilled medium helping to preserve the pristine content of the acquired samples. The drill consists of an actuator that simultaneously impacts and rotates the bit by applying force and torque via a single piezoelectric stack actuator without the need for a gearbox or lever mechanism. This can reduce the development/fabrication cost and complexity. In this paper, the drill mechanism will be described and the test results will be reported and discussed.

    Developing technologies that would enable NASA to sample rock, soil, and ice by coring, drilling or abrading at a significant depth is of great importance for a large number of in-situ exploration missions as well as for earth applications. Proven techniques to sample Mars subsurface will be critical for future NASA astrobiology missions that will search for records of past and present life on the planet, as well as the search of water and other resources. A deep corer, called Auto-Gopher, is currently being developed as a joint effort of the JPL's NDEAA laboratory and Honeybee Robotics Corp. The Auto-Gopher is a wire-line rotary- hammer drill that combines rock breaking by hammering using an ultrasonic actuator and cuttings removal by rotating a fluted bit. The hammering mechanism is based on the Ultrasonic/Sonic Drill/Corer (USDC) that has been developed as an adaptable tool for many of drilling and coring applications. The USDC uses an intermediate free-flying mass to transform the high frequency vibrations of the horn tip into a sonic hammering of a drill bit. The USDC concept was used in a previous task to develop an Ultrasonic/Sonic Ice Gopher. The lessons learned from testing the ice gopher were implemented into the design of the Auto-Gopher by inducing a rotary motion onto the fluted coring bit. A wire-line version of such a system would allow penetration of significant depth without a large increase in mass. A laboratory version of the corer was developed in the NDEAA lab to determine the design and drive parameters of the integrated system. The design configuration lab version of the design and fabrication and preliminary testing results are presented in this paper.

    Our objective was to describe the imaging features of hypothenar hammer syndrome using minimally invasive contrast-enhanced MR angiography in comparison with oscillography study. In five patients with hypothenar hammer syndrome Gd-BOPTA-enhanced elliptically reordered 3D pulse sequence MR was compared with oscillography findings and clinical symptoms focusing on angiographic appearance of vessel injury, distribution pattern of hand vasculature and joining branches between the radial and ulnar artery supply. All patients showed segmental occlusion at the site of trauma impact with varying involvement of the superficial palmar arch, common volar digital arteries. Embolic disease was present in 50% of patients and could be clearly identified with MRA. Good correspondence was found between angiographic appearance including the presence of collaterals, clinical symptoms and oscillography. Bilateral comparison was helpful in distinguishing between vessel variants and pathology. Bilateral Gd-BOPTA-enhanced MR angiography is a minimally invasive method to depict clearly the localization and extent of vessel injury in hypothenar hammer syndrome providing valuable information about distribution pattern of hand vasculature and presence of collaterals; however, no flow data can be obtained.

    Han, Seung-Ho; Han, Jeong-Woo; Nam, Yong-Yun; Cho, In-Ho

    For the improvement of fatigue strength of welded structures, mechanical post treatments have been applied in various industrial fields and have in most cases been founded to give substantial increases in their fatigue lives. These methods, generally, consist of the modification of weld toe geometry and the introduction of compressive residual stresses. In mechanical surface treatments, e.g. PHP (pneumatic hammer peening) and UNSM (ultrasonic nano-crystal surface modification), the weld profile is modified due to remove or reduce minute crack-like flaws, and compressive residual stresses are also induced. In this study, a pneumatic hammer peening procedure and a UNSM device were introduced, and a quantitative measure of fatigue strength improvement was performed. The fatigue strength at 2 × 106 cycles of hammer-peened and UNSM treated on a non-load carrying cruciform welded joint shows 220 and 260MPa, respectively, which are more than two times higher than that of as-welded specimen. Especially, the surface layer in the vicinity weld toe treated by the UNSM provides nano-crystal structure created by an ultrasonic cold forging and introduces very high welding residual stress in compression.

  10. On the prediction of impact noise, V: The noise from drop hammers

    1983-06-01

    In earlier papers in this series, the concepts of "acceleration" and "ringing" noise have been studied in relation to impact machines, and values of radiation efficiency have been obtained for the various types of structural components. In the work reported in this paper the predicted and measured noise radiation from a drop hammer, both in full-scale and in {1}/{3}- scale model form, were examined. It is found that overall noise levels ( Leq per event) can be predicted from vibration measurements to within ± 1·5 dB, and to within ±2·5 dB in one-third octave bands. In turn this has permitted noise reduction techniques to be examined by studies of local component vibration levels rather than overall noise, a method which provides considerable enlightenment at the design stage. It is shown that on one particular drop hammer, the noise energy is shared surprisingly uniformly over four or five sources, and that when these have been reduced, the overall noise reduction is severely limited by the "acceleration" noise from the "tup" or "hammer" itself. As this is difficult to eliminate without a basic change in forging technology, it follows that "tup" enclosure or modification of the sharpness of the final "hard" impact are the only means available for any serious noise reduction. Also indicated is the reliability of using model techniques, suitably scaled in frequency and impulse magnitude, in developing machinery with impact characteristics.

    1981-01-01

    Vehicles were characterized for the state of the art assessment of electric vehicles. The vehicle evaluated was a Chevrolet Corvette converted to electric operation. The original internal combustion engine was replaced by an electric traction motor. Eighteen batteries supplied the electrical energy. A controller, an onboard battery charger, and several dashboard instruments completed the conversion. The emphasis was on the electrical portion of the drive train, although some analysis and discussion of the mechanical elements are included. Tests were conducted both on the road (actually a mile long runway) and in a chassis dynamometer equipped laboratory. The majority of the tests performed were according to SAE Procedure J227a and included maximum effort accelerations, constant speed range, and cyclic range. Some tests that are not a part of the SAE Procedure J227a are described and the analysis of the data from all tests is discussed.

    The Fogarty International Center (FIC) has supported research capacity development for over twenty years. While the mission of FIC is supporting and facilitating global health research conducted by U.S. and international investigators, building partnerships between health research institutions in the U.S. and abroad, and training the next generation of scientists to address global health needs, research capacity may impact health policies and programs and therefore have positive impacts on public health. We conducted an exploratory analysis of how FIC research training investments affected public health policy and program development in Kenya and Uganda. We explored the long term impacts of all FIC supported research training programs using case studies, in Kenya and Uganda. Semi-structured in-depth interviews were conducted with 53 respondents and 29 focus group discussion participants across the two countries. Qualitative methods were supplemented by structured surveys of trainees and document review, including a review of evidence cited in policy documents. In the primary focal areas of FIC grants, notably HIV/AIDS, there were numerous examples of work conducted by former FIC trainees that influenced national and global policies. Facilitators for this influence included the strong technical skills and scientific reputations of the trainees, and professional networks spanning research and policy communities. Barriers included the fact that trainees typically had not received training in research communication, relatively few policy makers had received scientific training, and institutional constraints that undermined alignment of research with policy needs. While FIC has not focused its programs on the goal of policy and program influence, its investments have affected global and national public health policies and practice. These influences have occurred primarily through strengthening research skills of scientists and developing strong in-country networks

    Young, French male athletes undergoing intensive elite sports training at the National Training Centre in Clairefontaine served as the subjects (N = 180; age range: 13 to 16 years) in a 3-year dietary survey aimed at characterizing their nutritional intake in terms of energy, macronutrients, calcium, and iron. Each year, the subjects were grouped by level into 3 promotions so that 9 groups could be studied. Dietary intake data were collected each year for each subject in the 9 groups, using a 5-day food record. The results showed that their total energy intake (TEI) was insufficient for athletes (ranging from 2352 454 to 3395 396 kcal/d as opposed to the recommended range of between 3819 and 5185 kcal/d). Furthermore, their diet was unbalanced, with too great an emphasis upon fatty foods (29.1 2.8 to 34.1 3.1% TEI vs. the 20% recommended), to the detriment of carbohydrates (48.5 4.3 to 56.6 3.1% TEI vs. the 55 to 60% recommended). The calcium intake was too low in 5 of the 9 groups while, in contrast, the iron intake was satisfactory in all groups. Furthermore, during this 3-year period at the Clairefontaine Centre, the subjects significantly (p <.05) improved their calcium and iron intakes (1021 197 and 12 2 mg/d in 1996, 1299 155 and 16 2 mg/d in 1997, and 1252 184 and 17 2 mg/d in 1998). This rise in micronutrient intakes may have been due to a physiological adaptation to growth or to the positive effects of courses on nutrition given during their stay at the Centre.

    Rural communities disproportionately face preventable chronic diseases and death from treatable conditions. Health workforce shortages contribute to limited health care access and health disparities. Efforts to address workforce shortages have included establishing graduate medical education programs with the goal of recruiting and retaining physicians in the communities in which they train. However, rural communities face a number of challenges in developing and maintaining successful residency programs, including concerns over financial sustainability and the integration of resident trainees into existing clinical practices. Despite these challenges, rural communities are increasingly interested in investing in residency programs; those that are successful see additional benefits in workforce recruitment, access, and quality of care that have immediate and direct impact on the health of rural communities. This commentary examines the challenges and benefits of rural residency programs, drawing from lessons learned from the Health Resources and Services Administration's Teaching Health Center Graduate Medical Education program.

    New electrophysiology tools like intracardiac echocardiography (ICE) might help to minimize and early detect complications during cardiac ablation procedures. The aim of the study was to assess the utility and vascular safety of ICE during catheter ablation of complex cardiac arrhythmias in a medium-volume training center. Prospective, observational study consisted of consecutive patients who underwent catheter-based ablation of complex cardiac arrhythmias. All procedures were performed using three-dimensional electro-anatomical mapping and routine cannulation of right and left femoral veins. The ICE probe was initially positioned at the mid-level of the right atrium and properly moved to monitor different steps of the procedure and identify complications. All procedure-related vascular complications were registered. One hundred two patients (age 61.4 ± 13.1 years, 69 male) underwent 110 ablation procedures. Pulmonary vein isolation was the most common ablation substrate (55.4%). Ventricular tachycardia (17.2%) and left atrial flutter procedures (16.4%) were also common. The use of ICE enabled us to early initiate anticoagulation and to optimize the transseptal puncture. It also provided the capability to early detect life-threatening complications such as tamponade (3.6%), along with important information during the procedure such as exact catheter location, lesion formation, and stability during radiofrequency delivery. Such benefits were not associated with a higher number of vascular complications. The use of ICE during catheter-based ablation of complex cardiac substrates provides technical features that may decrease complications and increase accuracy while applying radiofrequency, especially in training centers where fellows start to perform complex procedures. © 2014, Wiley Periodicals, Inc.

    To determine if a program of intense Tai Chi exercise that has been shown to reduce the risk of falling in older adults improves postural control by altering the center of pressure (COP) trajectory during gait initiation. Before-after trial. Biomechanics research laboratory. Twenty-eight older adults transitioning to frailty who participated in either a 48-week intervention of intense Tai Chi training or a wellness education (WE) program. Eight Tai Chi forms emphasizing trunk rotation, weight shifting, coordination, and narrowing of lower-extremity stance were taught twice weekly. WE program participants met once a week and received lectures focused on health. Main outcome measures The COP was recorded during gait initiation both before and after the 48-week intervention by using a forceplate sampling at 300 Hz. The COP trajectory was divided into 3 periods (S1, S2, S3) by identifying 2 landmark events. Displacement and average velocity of the COP trace in the anteroposterior (x) and mediolateral (y) directions, as well as smoothness, were calculated. Tai Chi training increased the posterior displacement of the COP during S1 and improved the smoothness of the COP during S2. Tai Chi improved the mechanism by which forward momentum is generated and improved coordination during gait initiation, suggesting improvements in postural control.

    Courses are an important way of cultivating talents in college education. Advanced training schemes and the course system are implemented through course teaching. Advanced teaching notions and methods also rely on course teaching. Therefore, the quality of course teaching is the fundamental guarantor for grooming talent. The teachers of the course "Microcontroller Principles and Interface Techniques" in the Optical Science and Engineering College of Zhejiang University insist on course teaching becoming student centered and ability-training-oriented. They pay attention to students'all-round development in terms of learning ability, practical ability, innovation ability, and exploring spirit. They actively carried out course reforms in four aspects, namely teaching, learning, evaluation, and experimentation. This paper mainly introduced these reforms. First, the teaching method was reformed by introducing case analysis and the notion of a flipped classroom to shift the course focus from the teacher to the students. Second, the learning method was reformed through the use of techniques such as peer learning and project design to promote students' sense of enquiry and learning initiative. Third, the evaluation method was reformed through the use of process assessment and diversity evaluation to encourage students to develop logical thinking and a down-to-earth manner. Fourth, the experimentation method was reformed by introducing hierarchical content, process management, and diversification of examination to change students'learning attitude from "dependence, passivity, and imitation" to "independence, active involvement, and creation."In general, the teaching method reform promoted reforms in learning, evaluation, and experimentation methods and further improved the style of study. These reforms improved teachers' teaching abilities and enabled course teaching to transform from being teacher centered to student centered. Years of exploration and practice results have

    This work investigates a two dimensional numerical analysis of blood hammer through the posterior cerebral artery. The non-Newtonian and usual Newtonian blood models are compared in the case of blood hammer through the posterior cerebral artery to quantify the differences between the models. In this way, a validated CFD simulation is used to study non-Newtonian shear-thinning effects of blood. The governing equations for the modeling of two-dimensional transient flow are solved using a combination of characteristics and central finite difference methods, respectively for the hyperbolic and parabolic parts. Herein, the non-Newtonian viscosity characteristic of blood is incorporated by using the Carreau model. To convert the nonlinear terms available in the characteristics equation into the linear ones, the Newton-Kantorovich method is implemented. The verification and validation of the numerical results are carried out in detail. Hemodynamic characteristics of blood hammer through the posterior cerebral artery are derived with both the Newtonian and non-Newtonian models, and the results are meticulously compared and discussed. The results show that when blood hammer occurs, the non-Newtonian properties greatly influence the velocity and shear stress profiles. At the early stages of blood hammer, there is a 64% difference between magnitudes of wall shear stress in these two models, and the magnitude of the wall shear stress for the shear-thinning blood flow is lower than the Newtonian one.

    Measures of second-fourth metatarsophalangeal joint (MTPJ) angle (indicator of hammer toe deformity) and clinical measures of tibial torsion have limited evidence for validity and reliability. The purposes of this study are to determine: (1) reliability of using a 3D digitizer (Metrecom) and computed tomography (CT) to measure MTPJ angle for toes 2-4; (2) reliability of goniometer, 3D digitizer, and CT to measure tibial torsion; (3) validity of MTPJ angle measures for toes 2-4 using goniometry and 3D digitizer compared to CT (gold standard) and (4) validity of tibial torsion measures using goniometry and 3D digitizer (Metrecom) compared to CT (gold standard). Twenty-nine subjects participated in this study. 27 feet with hammer toe deformity and 31 feet without hammer toe deformity were tested using standardized gonimetric, 3D digitizer and CT methods. ICCs (3,1), standard error of the measurement (SEM) values, and difference measures were used to characterize intrarater reliability. Pearson correlation coefficients and an analysis of variance were used to determine associations and differences between the measurement techniques. 3D digitizer and CT measures of MTPJ angle had high test-retest reliability (ICC = 0.95-0.96 and 0.98-0.99, respectively; SEM = 2.64-3.35 degrees and 1.42-1.47 degrees, respectively). Goniometry, 3D digitizer, and CT measures of tibial torsion had good test-retest reliability (ICC = 0.75, 0.85, and 0.98, respectively; SEM = 2.15 degrees, 1.74 degrees, and 0.72 degree, respectively). Both goniometric and 3D digitizer measures of MTPJ angle were highly correlated with CT measures of MTPJ angle (r = 0.84-0.90, r = 0.84-0.88, respectively) and tibial torsion (r = 0.72, r = 0.83). Goniometry, 3D digitizer, and CT measures were all different from each other for measures of hammer toe deformity (p Goniometry measures were different from CT measures and 3D digitizer measures of tibial torsion (p reliable.

    The authors describe the development and implementation of a new adult psychiatry residency didactic curriculum based on adult learning principles and an integrative, patient-centered approach that includes a progressive 4-year neuroscience curriculum. The authors describe the process of conducting a needs assessment, engaging stakeholders and developing guiding principles for the new curriculum. The curriculum was evaluated using qualitative measures, a resident survey, course evaluations, and a pilot version of a specialized assessment tool. Feedback from the resident survey and from course evaluations was positive, and residents indicated interest in receiving additional training in neuroscience. Residents self-reported not incorporating neuroscience into formulation and treatment planning as often as other perspectives. They also reported that neuroscience was reinforced less by clinical faculty than other perspectives. Performance on the curriculum assessment corroborated that clinical application of neuroscience may benefit from additional reinforcement. Residents responded well to the design and content of the new didactic curriculum. The neuroscience component appears to have achieved its primary objective of enhancing attitudes to the field. Continued work including enhancing the culture of neuroscience at the clinical sites may be required to achieve broader behavioral goals.

    Full Text Available When operating the anvil hammers there occur impacts of die tooling and as a consequence, virtually instantaneous impact stops of motion of drop hammer parts. Such operating conditions come with accelerated failures of the anvil hammer rods because of emerging significant wave stresses. Engineering practice widely uses variation, difference, and integral methods to calculate wave stresses. However, to use them a researcher has to acquire certain skills, and the special programs should be available. The paper considers a method for estimating the wave stress changes in the anvil hammer rods, which is based on the wave equation of the Laplace transform. It presents a procedure for generating differential equations and their solution using the operator method. These equations describe the wave processes of strain and stress propagation in the anvil hammer rod under non-rigid impact with the compliance obstacle of the drop hammer parts. The work defines how the piston and rod mass and also the mechanical and geometric parameters of the rod influence on the stress level in the rod sealing of the hammer ram. Analysis of the results shows that the stresses in the rod sealing are proportional to the total amount of wave stresses caused by the rod and piston impact included in the total weight of the system. The piston influence on the stresses in the rod under impact is in direct proportion to the ratio of its mass to the mass of the rod. Geometric parameters of the rod and speed of drop parts before the impact influence on the stress value as well. It was found that if the time of impact is less than the time of the shock wave running in forward and backward direction, the impact with a compliance obstacle is equivalent to that of with a rigid obstacle, and the dependence of the wave stresses follows the Zhukovsky formula of direct pressure shock. The presented method of stress calculation can be successfully used to select the optimal mass and the rod

    Full Text Available Complex phenomena, as water hammer transients, occurring in nuclear power plants are still not very well investigated by the current best estimate computational tools. Within this frame work, a rapid positive reactivity addition into the core generated by a water hammer transient is considered. The numerical simulation of such phenomena was carried out using the coupled RELAP5/PARCS code. An over all data comparison shows good agreement between the calculated and measured core pressure wave trends. However, the predicted power response during the excursion phase did not correctly match the experimental tendency. Because of this, sensitivity studies have been carried out in order to identify the most influential parameters that govern the dynamics of the power excursion. After investigating the pressure wave amplitude and the void feed back responses, it was found that the disagreement between the calculated and measured data occurs mainly due to the RELAP5 low void condensation rate which seems to be questionable during rapid transients. .

    Brookhaven Lab’s perfluorocarbon tracer (PFT) technology can be viewed as a hammer looking for nails. But, according to Tom Watson, leader of the Lab’s Tracer Technology Group in the Environmental Research and Technology Division (ERTD), “It’s a really good hammer!” The colorless, odorless and safe gases have a number of research uses, from modeling how airborne contaminants might move through urban canyons to help first responders plan their response to potential terrorist attacks and accidents to locating leaks in underground gas pipes. Their extremely low background level — detectable at one part per quadrillion — allows their transport to be easily tracked. Lab researchers used PFTs during the 2005 Urban Dispersion Program field studies in New York City, gathering data to help improve models of how a gas or chemical release might move around Manhattan’s tall buildings and canyons. Closer to home, scientists also used PFTs to make ventilation measurements in Bldg. 400 on the Lab site to provide data to test air flow models used in determining the effects of passive and active air exchange on the levels of indoor and outdoor air pollution, and to determine the effects of an accidental or intentional release of hazardous substances in or around buildings.

    During a loss of coolant accident (LOCA) the pressure of the coolant can drop significantly in the vicinity of the leak. It will be shown that unlike in pressurized water reactors (PWRs) where this pressure drop can cause only sudden vaporization - also called flashing - in supercritical water cooled reactors (SCWRs) it can cause sudden condensation (condensation-induced water hammer), too. The reason is that from supercritical state the system can go to metastable liquid as well as to metastable vapour state after LOCA. Relaxation from metastable fluid states is a fast process, followed by a local positive or negative pressure-jump, which might increase the damage around the leak. Conservative estimation will be given for the magnitude of these pressure jumps caused by the flashing or water hammer by assuming various initial pressure losses. In our calculations, three different equations of state are used: the simple van der Waals EoS; the Redlich-Kwong as an empirical development; and the more sophisticated non-cubic Deiters equation of state. These equations are able to describe metastable states qualitatively but with different accuracy. These calculations can help us to map the local immediate effect of any sudden pressure drop and therefore it can help to design better safety protocols.

    Full Text Available Using a no-moving-component output-fed bistable fluidic oscillator to control fluid flows into a parallel path has been recognized for a considerable time, but as yet it is not so widely adopted as its obvious benefits would deserve. This may be attributed to the encountered problems associated with its jet behavior, complicated by its loading characteristics. In order to investigate a typical case for the application of the output-fed fluidic oscillator, this paper elaborates on the computational fluid dynamics (CFD simulation method for studying the performance of a fluidic hammer controlled by an output-fed bistable fluidic oscillator. Given that couple mechanism exists between the flow field in the fluidic oscillator and the impact body, dynamic mesh technique and a user-defined function written in C programming language were used to update the mesh in the simulations. In terms of the evaluation of performance, the focus is on the single-impact energy and output power of the fluidic hammer in this study, to investigate the effect of different parameters of the impact body on them. Experimental tests based on the noncontact measuring method were conducted to verify the simulation results, by which the accuracy and reliability of this CFD simulation method was proved.

    Equine herpesvirus type 1 (EHV-1) is a major cause of winter pyrexia in racehorses in two training centers (Ritto and Miho) in Japan. Until the epizootic period of 2008-2009, a vaccination program using a killed EHV-1 vaccine targeted only susceptible 3-year-old horses with low antibody levels to EHV-1 antigens. However, because the protective effect was not satisfactory, in 2009-2010 the vaccination program was altered to target all 3-year-old horses. To evaluate the vaccine's efficacy, we investigated the number of horses with pyrexia due to EHV-1 or equine herpesvirus type 4 (EHV-4) infection or both and examined the vaccination coverage in the 3-year-old population and in the whole population before and after changes in the program. The mean (± standard deviation [SD]) estimated numbers of horses infected with EHV-1 or EHV-4 or both, among pyretic horses from 1999-2000 to 2008-2009 were 105 ± 47 at Ritto and 66 ± 44 at Miho. Although the estimated number of infected horses did not change greatly in the first period of the current program, it decreased from the second period, with means (±SD) of 21 ± 12 at Ritto and 14 ± 15 at Miho from 2010-2011 to 2012-2013. Vaccination coverage in the 3-year-old population was 99.4% at Ritto and 99.8% at Miho in the first period, and similar values were maintained thereafter. Coverage in the whole population increased more gradually than that in the 3-year-old population. The results suggest that EHV-1 epizootics can be suppressed by maintaining high vaccination coverage, not only in the 3-year-old population but also in the whole population. PMID:24872513

    The U.S. Army Fort Irwin National Training Center (NTC), in the Mojave Desert, obtains all of its potable water supply from three groundwater basins (Irwin, Langford, and Bicycle) within the NTC boundaries (fig. 1; California Department of Water Resources, 2003). Because of increasing water demands at the NTC, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army, completed several studies to evaluate water resources in the developed and undeveloped groundwater basins underlying the NTC. In all of the developed basins, groundwater withdrawals exceed natural recharge, resulting in water-level declines. However, artificial recharge of treated wastewater has had some success in offsetting water-level declines in Irwin Basin. Additionally, localized water-quality changes have occurred in some parts of Irwin Basin as a result of human activities (i.e., wastewater disposal practices, landscape irrigation, and/or leaking pipes). As part of the multi-faceted NTC-wide studies, traditional datacollection methods were used and include lithological and geophysical logging at newly drilled boreholes, hydrologic data collection (i.e. water-level, water-quality, aquifer tests, wellbore flow). Because these data cover a small portion of the 1,177 square-mile (mi2 ) NTC, regional mapping, including geologic, gravity, aeromagnetic, and InSAR, also were done. In addition, ground and airborne electromagnetic surveys were completed and analyzed to provide more detailed subsurface information on a regional, base-wide scale. The traditional and regional ground and airborne data are being analyzed and will be used to help develop preliminary hydrogeologic framework and groundwater-flow models in all basins. This report is intended to provide an overview of recent water-resources and land-surface deformation studies at the NTC.

  4. Identification of noise sources of forge hammers during production: An application of residual spectrum techniques to transients

    Trethewey, M. W.; Evensen, H. A.

    1981-08-01

    Three gravity-drop, four-piece forge hammers are analyzed to determine the principal structural sources of impulsive noise radiation during production forging. A three-input single-output model is used to describe the hammer system, based on "input" signals taken from one column, the anvil and the ram accelerations, and one "output" signal taken from the sound pressure at the operator's position. The frequency response functions between the elemental vibrations and the sound pressure signal are determined from these signals by residual spectrum techniques. For the three hammers studied, the analysis shows that the ram is a major source of acoustic energy radiated to the oeprator's position, while the columns and anvil radiate between 1 and 4 dB less energy. The three-input model is then used to estimate the effect of acoustic shrouds on the sound energy radiation. The results indicate that it may be necessary to treat all the structural elements before significant reductions can be achieved, due mainly to the high degree of interaction between the components. The residual spectrum derived from this model indicates that the three input model may not be totally adequate for all production hammers; it may be necessary to develop higher-input models, with use of data from more transducers located to sense a higher number of contributing vibration modes. However, in this study the three-input model accounted for 73-82% of the sound energy density at the operator's position.

    This study examined the validity of a broad set of predictors for selecting European managers for a cross-cultural training program in Japan. The selection procedure assessed cognitive ability, personality, and dimensions measured by assessment center exercises and a behavior description interview. Results show that the factor Openness was significantly related to cross-cultural training performance, whereas cognitive ability was significantly correlated with language acquisition. The dimensions of adaptability, teamwork, and communication as measured by a group discussion exercise provided incremental variance in both criteria, beyond cognitive ability and personality. In general, these results are consistent with the literature on domestic selection, although there are some important differences.

    The goal of this collaboration between a university and two community mental health (CMH) centers was to increase capacity among staff serving children with autism spectrum disorder (ASD) in usual care social skills groups. University researchers observed two usual care social skills groups in two sites; identified needs and strengths; delivered tailored trainings on behavioral management principles; and provided follow-up coaching. After training and coaching, CMH staff demonstrated significant gains in self-reported and observed behavioral management skills. Foundational education in behavior management may benefit successful implementation of ASD-specific evidence based practices in community settings.

  7. New developments with Schmidt-hammer exposure-age dating (SHD): Comparison of mechanical and electronic Schmidt-hammers - towards a conversion factor for Q- and R-values

    2014-05-01

    Developed as an instrument for in situ destruction-free testing of concrete hardness in construction works, the Schmidt-hammer has subsequently been introduced and applied in various fields of geomorphology and geology. In the context of investigating Late Glacial and Holocene glacier chronologies, the Schmidt-hammer has been widely used as a relative-age dating technique. Such applications have for example successfully separated moraines formed during different glacier advance periods ('Little Ice Age'-type events). Pilot studies combined Schmidt-hammer measurements with available radiocarbon ages in order to achieve age constraints. Schmidt-hammer exposure-age dating (SHD) combining Schmidt-hammer and terrestrial cosmogenic nuclide dating (TCND) has recently been successfully applied in Norway and New Zealand. Schmidt-hammer tests have also been used to ensure the representativeness of boulders selected for TCND sampling. Especially in mountain regions with a high "geomorphological uncertainty" with the dating of Holocene moraines the inherited multi-proxy approach of SHD owns a considerable potential for reliable investigations of Late Glacial/Holocene glacier chronologies and their palaeoclimatic interpretation. An electronic Schmidt-hammer (named SilverSchmidt) was introduced by the manufacturer of the original mechanical Schmidt-hammer (Proceq SA) a few years ago. It offers especially facilities for much easier data processing and constitutes, therefore, a major improvement and potential replacement for the mechanical Schmidt-hammer. However, its different approach to the measurement of surface hardness - based on Q-(velocity) values instead of R-(rebound) values - means that measurements from the two instruments are not easily interconvertible. Prior to any considerations of using the instruments interchangeably or replacing the mechanical Schmidt-hammer in future studies with the SilverSchmidt, comparative tests under field conditions need to be undertaken

    Stemming the tide of noncommunicable diseases (NCDs) worldwide requires a multipronged approach. Although much attention has been paid to disease control measures, there is relatively little consideration of the importance of training the next generation of health-related researchers to play their important role in this global epidemic. The lack of support for early stage investigators in low- and middle-income countries interested in the global NCD field has resulted in inadequate funding opportunities for research, insufficient training in advanced research methodology and data analysis, lack of mentorship in manuscript and grant writing, and meager institutional support for developing, submitting, and administering research applications and awards. To address this unmet need, The National Heart, Lung, and Blood Institute-UnitedHealth Collaborating Centers of Excellence initiative created a Training Subcommittee that coordinated and developed an intensive, mentored health-related research experience for a number of early stage investigators from the 11 Centers of Excellence around the world. We describe the challenges faced by early stage investigators in low- and middle-income countries, the organization and scope of the Training Subcommittee, training activities, early outcomes of the early stage investigators (foreign and domestic) and training materials that have been developed by this program that are available to the public. By investing in the careers of individuals in a supportive global NCD network, we demonstrate the impact that an investment in training individuals from low- and middle-income countries can have on the preferred future of or current efforts to combat NCDs.

    In the present study, specific energy for grinding and physical properties of wheat, canola, oat and barley straw grinds were investigated. The initial moisture content of the straw was about 0.13–0.15 (fraction total mass basis). Particle size reduction experiments were conducted in two stages: (1) a chopper without a screen, and (2) a hammer mill using three screen sizes (19.05, 25.4, and 31.75 mm). The lowest grinding energy (1.96 and 2.91 kWh t-1) was recorded for canola straw using a chopper and hammer mill with 19.05-mm screen size, whereas the highest (3.15 and 8.05 kWh t-1) was recorded for barley and oat straws. The physical properties (geometric mean particle diameter, bulk, tapped and particle density, and porosity) of the chopped and hammer-milled wheat, barley, canola, and oat straw grinds measured were in the range of 0.98–4.22 mm, 36–80 kg m-3, 49–119 kg m-3, 600–1220 kg m-3, and 0.9–0.96, respectively. The average mean particle diameter was highest for the chopped wheat straw (4.22-mm) and lowest for the canola grind (0.98-mm). The canola grinds produced using the hammer mill (19.05-mm screen size) had the highest bulk and tapped density of about 80 and 119 kg m-3; whereas, the wheat and oat grinds had the lowest of about 58 and 88–90 kg m-3. The results indicate that the bulk and tapped densities are inversely proportional to the particle size of the grinds. The flow properties of the grinds calculated are better for chopped straws compared to hammer milled using smaller screen size (19.05 mm).

    Experimental MS(n) mass spectral libraries currently do not adequately cover chemical space. This limits the robust annotation of metabolites in metabolomics studies of complex biological samples. In silico fragmentation libraries would improve the identification of compounds from experimental multistage fragmentation data when experimental reference data are unavailable. Here, we present a freely available software package to automatically control Mass Frontier software to construct in silico mass spectral libraries and to perform spectral matching. Based on two case studies, we have demonstrated that high-throughput automation of Mass Frontier allows researchers to generate in silico mass spectral libraries in an automated and high-throughput fashion with little or no human intervention required. Documentation, examples, results and source code are available at http://www.biosciences-labs.bham.ac.uk/viant/hammer/.

    Full Text Available The easy detection of fouling in duct systems is a persistent problem and remains a relevant demand for the chemical, oil, food and pharmaceutical industries. The fouling process is the slow, unwanted layer deposition of heavy organic and other dissolved solid materials out of transported fluids or suspensions onto inner wall surfaces in fluid transport systems over an extended period of time. This work presents research results of vibrational hammer excitation for easy to use external non-invasive, non-destructive fouling detection in pipelines and other large scale duct systems. The main goal is the detection of inner pipe layer formation, and thickness estimation of the adsorbed material. Data were taken from the vibration amplitude variation in presence of an inner pipe fouling layer using acoustic accelerometer and microphone detection. The experimental set-up and achievable sensitivities and of the methods are outlined.

    The tendon tap reflex (T-reflex) is often evoked in relaxed muscles to assess spinal reflex circuitry. Factors contributing to reflex excitability are modulated to accommodate specific postural demands. Thus, there is a need to be able to assess this reflex in a state where spinal reflex circuitry is engaged in maintaining posture. The aim of this study was to determine whether a pendulum hammer could provide controlled stimuli to the Achilles tendon and evoke reliable muscle responses during normal stance. A second aim was to establish appropriate stimulus parameters for experimental use. Fifteen healthy young adults stood on a forceplate while taps were applied to the Achilles tendon under conditions in which postural sway was constrained (by providing centre of pressure feedback) or unconstrained (no feedback) from an invariant release angle (50°). Twelve participants repeated this testing approximately six months later. Within one experimental session, tap force and T-reflex amplitude were found to be reliable regardless of whether postural sway was constrained (tap force ICC=0.982; T-reflex ICC=0.979) or unconstrained (tap force ICC=0.968; T-reflex ICC=0.964). T-reflex amplitude was also reliable between experimental sessions (constrained ICC=0.894; unconstrained ICC=0.890). When a T-reflex recruitment curve was constructed, optimal mid-range responses were observed using a 50° release angle. These results demonstrate that reliable Achilles T-reflexes can be evoked in standing participants without the need to constrain posture. The pendulum hammer provides a simple method to allow researchers and clinicians to gather information about reflex circuitry in a state where it is involved in postural control.

    Frequent validation and stress testing of the network, storage and CPU resources of a grid site is essential to achieve high performance and reliability. HammerCloud was previously introduced with the goals of enabling VO- and site-administrators to run such tests in an automated or on-demand manner. The ATLAS, CMS and LHCb experiments have all developed VO plugins for the service and have successfully integrated it into their grid operations infrastructures. This work will present the experience in running HammerCloud at full scale for more than 3 years and present solutions to the scalability issues faced by the service. First, we will show the particular challenges faced when integrating with CMS and LHCb offline computing, including customized dashboards to show site validation reports for the VOs and a new API to tightly integrate with the LHCbDIRAC Resource Status System. Next, a study of the automatic site exclusion component used by ATLAS will be presented along with results for tuning the exclusion policies. A study of the historical test results for ATLAS, CMS and LHCb will be presented, including comparisons between the experiments’ grid availabilities and a search for site-based or temporal failure correlations. Finally, we will look to future plans that will allow users to gain new insights into the test results; these include developments to allow increased testing concurrency, increased scale in the number of metrics recorded per test job (up to hundreds), and increased scale in the historical job information (up to many millions of jobs per VO).

    The American Board of Surgery In-Training Exam (ABSITE) is administered to all general surgery residents annually. Given the recent changes in the format of the examination and in the material being tested, it has become increasingly difficult for residents to prepare for the ABSITE. This is especially true for incoming postgraduate year (PGY) 1 residents because of the respective variability of the surgical clerkship experience. There have been many studies in the past that support the use of weekly assigned readings and examinations to improve ABSITE scores. Other studies have investigated the study habits of residents to determine those that would correlate with higher ABSITE scores. However, there is a lack of information on whether completing review questions plays an integral role in preparing for the ABSITE. We hypothesize that those residents who completed more review questions performed better on the ABSITE. ABSITE scores of current and past general surgery residents at SUNY Downstate Medical Center, a university hospital, were reviewed (2009-2013). These residents were then polled to determine how they prepared for their first in-training examination. Average ABSITE percentile was 46.4. Mean number of review questions completed by residents was 516.7. Regression analysis showed that completion of more review questions was associated with a significantly higher percentile score on the ABSITE (p < 0.0027). Further analysis showed that for every 100 review questions completed by a PGY 1 resident taking the ABSITE for the first time, the ABSITE percentile score should improve by 3.117 ± 0.969. Average reported study time in hours/week was 9.26. Increased study time was also significantly correlated with higher ABSITE percentile scores (p < 0.007). Again, further analysis showed that for every 1h/wk spent studying, ABSITE percentile score should increase by 1.76 ± 0.62. The Kruskal-Wallis H test showed that studying in group vs individual settings had no

    Many monuments and cities that are part of humanity's heritage have been built with carved granite ashlars. This dimension stone is one of the most used due to its abundance and durability. Traditional quarrymen have used anisotropic planes to cut granite blocks in the quarry for improved cutting performance. These planes are called Rift, Grain and Hardway (R, G, H) according to the ease of cutting. The aim of this study is to determine the response of each of the three orthogonal cutting planes R, G and H to the craft styling with bush hammer, based on their decay. Alpedrete granite was selected for this research, it is a monzogranite quarried in the Sierra de Guadarrana (Spanish Central System) foothills, in the province of Madrid, Spain. It is one of the most representative of Madrid's heritage granites. Alpedrete granite is also used as building stone in other European cities. From an Alpedrete granite bush hammered ashlar, three thin sections were cut parallel to the H plane; these thin sections cut R and G bush hammered planes. Also three thin sections have been cut parallel to the R plane at a distance of 2 mm, 10 mm and 30 mm from the bush hammered surface. All thin sections have been treated with fluorescein. In each of the thin sections a micrograph mosaic was performed covering the entire area (about 10 cm2, 300 photomicrographs) and printed with 120 increases. The length and spacing of inter-, intra- and trans-crystalline microcracks were quantified and measured. Microcracks were subdivided based on affected minerals in each R, G and H planes. Through these observations it was found that Alpedrete Granite R plane (easier to cut) is determined by exfoliation microcracks orientation. That is, R plane is parallel to the exfoliations microcracks, which are intra-crystalline and straight. The cutting of stones in the R plane is due to the coalescence of straight microcracks in the plane. This plane minimizes the effort and cost of subsequent carving so it

    In the old Norse mythology Thor was a hammer-wielding god associated with thunder and lightning. THOR is also an acronym for Turbulence Heating ObserveR - a planned space mission dedicated to stydy space plasma turbulence. Whereas the mythological Thor did most of his work with a single tool, Mjølnir - his hammer, the modern version of THOR is far more versatile. The proposed THOR spacecraft comes with a comprehensive package of instruments to explore the energy dissipation and particle energization taking place in turbulent plasma environments. This paper presents a more detailed investigation of some of the analysis methods listed in the submitted THOR proposal. To demonstrate the methods, we have used data from existing spacecraft missions like Cluster and MMS to examine and compare single-spacecraft and multi-spacecraft methods to establish proper frames. The presented analysis methods are based on fundamental plasma laws, such as conservation of mass, momentum and energy and do not require any triangulation or gradients based on multiple spacecraft. Our experience based on Cluster and MMS results show that a well equipped single spacecraft platform, like the proposed THOR mission, very often provides better and less ambiguous results that a constellation of many spacecraft with less capable instrumentation. Limitations in underlying assumptions, such as planarity and linearity, as well as non-optimal spacecraft separation and configurations often limit the possibility to utilize multi-spacecraft methods. We also investigate the role of time resolution and dynamical range of the measurements used in the methods. Since the particle instruments onboard THOR will have a much better time resolution than existing magnetospheric satellite missions, we infer that THOR will be far better suited to resolve time evolution in plasma structures. This is of particular importance in the solar wind and magnetosheat, where frame velocities can be very high. With a larger

    Geologic material properties are necessary parameters for ground motion modeling and are difficult and expensive to obtain via traditional methods. Alternative methods to estimate soil properties require a measurement of the ground's response to a force. A possible method of obtaining these measurements is active-source seismic surveys, but measurements of the ground response at the source must also be available. The potential of seismic sources to obtain soil properties is limited, however, by the repeatability of the source. Explosives, and hammer surveys are not repeatable because of variable ground coupling or swing strength. On the other hand, the Seismic Hammer TM (SH) is consistent in the amount of energy it inputs into the ground. In addition, it leaves large physical depressions as a result of ground compaction. The volume of ground compaction varies by location. Here, we hypothesize that physical depressions left in the earth by the SH correlate to energy recorded by nearby geophones, and therefore are a measurement of soil physical properties. Using measurements of the volume of shot holes, we compare the spatial distribution of the volume of ground compacted between the different shot locations. We then examine energy recorded by the nearest 50 geophones and compare the change in amplitude across hits at the same location. Finally, we use the percent difference between the energy recorded by the first and later hits at a location to test for a correlation to the volume of the shot depressions. We find that: * Ground compaction at the shot-depression does cluster geographically, but does not correlate to known surface features. * Energy recorded by nearby geophones reflects ground refusal after several hits. * There is no correlation to shot volume and changes in energy at particular shot locations. Deeper material properties (i.e. below the depth of surface compaction) may be contributing to the changes in energy propagation. * Without further

    This paper proposes the Active Precharge Hammering on a Row (APHR) test to evaluate displacement damage (DD) in 3x-nm DRAM components. Irradiated SDRAM devices could have multiple current leakage paths, partly owing to DD effects. The degree of leakage from cells with DD can be differentiated from undamaged cells by the difference in the number of hammered accesses to the two types of cells. Proton-based SER tests were performed with DDR3 SDRAM components made using 3x-nm technologies. The experimental results showed that bit errors caused by the APHR test (APHR errors) were more than five times higher in the irradiated sample compared to the non-irradiated sample, and APHR errors were not detectable within 64-ms retention time using the traditional retention test method. In the worst case, the number of hammerings required to cause an APHR error in the irradiated sample reduced by 36 times compared to that in the non-irradiated sample even after the irradiated sample was annealed at 150° C so as to have no retention errors within the maximum retention time of 64-ms.

    Full Text Available Hydraulic hammers have been extensively applied to horizontal directional well drilling in hard rock formations. However, the service life of a hydraulic hammer is still unsatisfactory due to the heavy wear or abrasion of the horizontal anvil, which leads to the failure and the reduction of service life in directional well drilling. In order to improve the performance life of a hydraulic hammer, the new type of anvil with a horizontal oriented slider has been designed. The abrasion property of the horizontal oriented slider have been numerically simulated and analyzed by Finite Element Analysis. Simulation and experimental results have shown that the abrasion rate exponentially varies with the mass of the anvil and the friction coefficient of horizontal oriented slider, nevertheless the abrasion rate of horizontal anvil is almost logarithmically varies with moving velocity of oriented slider. The maximum abrasion rate of horizontal oriented sliders will exceed 4% while moving velocity of the horizontal anvil is larger than 3m/s. While the mass of the anvil is 100kg, the maximum abrasion rate of horizontal oriented slider is 7.5?. However, the maximum abrasion rate of a horizontal oriented slider will be up to 16.5% while the friction coefficient is more than 0.2

    In this study, we compared the effects of cryogenic grinding and hammer milling on the flavour attributes of black, white, and green pepper. The flavour attributes were analysed using headspace solid-phase micro-extraction (HS-SPME) and gas chromatography-mass spectrometry (GC/MS), sensory evaluation and electronic nose (e-nose) analysis. Cryogenic grinding resulted in minimal damage to the colour, flavour, and sensory attributes of the spices. Cryogenic grinding was also better than hammer milling at preserving the main potent aroma constituents, but the concentrations of the main aroma constituents were dramatically reduced after storing the samples at 4 °C for 6 months. Pattern matching performed by the e-nose further supported our sensory and instrumental findings. Overall, cryogenic grinding was superior to hammer milling for preserving the sensory properties and flavour attributes of pepper without significantly affecting its quality. However, we found that the flavour quality of ground pepper was reduced during storage. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Recent data suggest that exercise training (ET) confers significant symptomatic and functional improvements in patients with diastolic dysfunction, and thus may be beneficial in patients with hypertrophic cardiomyopathy (HCM). However, there are no data regarding the safety or efficacy of ET in HCM patients. A prospective non-randomized intervention design was used. We enrolled 20 patients with symptomatic HCM, significantly limited in everyday activity, into a supervised cardiac rehabilitation exercise program. Patients were 62 ± 13 years old, in New York Heart Association (NYHA) functional class II (35%) or III (65%), had a mean interventricular septum dimension of 17 ± 5 mm and left ventricular ejection fraction (LVEF) of 53 ± 15%. Left ventricular outflow gradient was present at rest in nine patients (mean 51 ± 24 mm Hg) and six patients had an implantable defibrillator. Exercise prescription was based on heart rate reserve (HRR) determined from a symptom-limited graded exercise stress test. Exercise intensity was gradually increased from 50% to 85% of the HRR over the training period. Patients completed an average of 41 ± 8 hours of aerobic ET. No adverse events or sustained ventricular arrhythmias occurred during the training program. Functional capacity, assessed by a graded exercise test, improved from 4.7 ± 2.2 to 7.2 ± 2.8 metabolic equivalents (METs) (p = 0.01). NYHA functional class improved from baseline by ≥ 1 grade in 10 patients (50%) and none experiencing deterioration during follow-up. The present study suggests that patients with HCM who remain symptomatic despite medical therapy may achieve considerable functional improvement through a supervised ET program. © The European Society of Cardiology 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    2014-02-01

    Dexterous behavior exhibits exquisite context sensitivity, implying the efficacy of exploration to detect the task-relevant information. Inspired by the recent finding that fractal scaling of exploratory movements predicts how well the movements sample available perceptual information, we investigate the possibility that dexterity of craftsmen would be characterized by fractal (long-range) temporal correlation properties of fluctuations in their movement wielding a tool. A reanalysis of hammering behavior involved in stone beads production in India (Nonaka & Bril, 2012) revealed the presence of long-range, power-law correlations, as part of multiplicative cascades operating over a wide range of time scales. In the unfamiliar condition using unusual material, the wielding behavior of highly skilled experts displayed a significant increase of long-range temporal correlations, whereas that of less experts exhibited a significant loss of long-range correlations and reduced heterogeneity of scaling properties over time, which robustly discriminated the groups with different skill levels. Alterations in long-range correlation properties of movement fluctuations are apparently associated with changes in the situation differently depending on the level of expertise.

  8. A focused liquid jet formed by a water hammer in a test tube

    2015-01-01

    We investigate motion of a gas-liquid interface in a test tube induced by a large acceleration via impulsive force. We conduct simple experiments in which the tube partially filled with a liquid falls under gravity and impacts a rigid floor. A curved gas-liquid interface inside the tube reverses and eventually forms an elongated jet (i.e. the so-called a focused jet). In our experiments, there arises either vibration of the interface or increment in the velocity of a liquid jet accompanied by the onset of cavitation in the liquid column. These phenomena cannot be explained by considering pressure impulse in a classical potential flow analysis, which does not account for finite speeds of sound as well as phase change. Here we model such water-hammer events as a result of one-dimensional pressure wave propagation and its interaction with boundaries through acoustic impedance mismatching. The method of characteristics is applied to describe pressure wave interactions and the subsequent cavitation. The proposed m...

    Sudden pressure increases in the penstock or spiral case of a hydraulic turbine are the effect of sudden flow variation that occur during transient processes of type opening / closing or load rejection of the hydro unit. The consequence of the pressure rise in the spiral case and penstock is the water hammer phenomenon, whose effects can be devastating in some cases, up to breaking pipes and calamities produced in the area. This paper aims to analyze the method of calculation of the maximum pressure values that might occur in load rejection situations to a hydraulic turbine, in spiral case and in penstock, conditioned by the limiting of the values of the over speed and measures of limiting the increase in pressure in conjunction with limiting the increase in speed in these specific processes. As an example, we studied and analyzed the situation of a hydroelectric power plant equipped with a 7.8 MW Francis turbine without pressure regulator and the inflow surge. The results of analytical calculation overlaid on the experimental measurements performed during the performance tests of the hydro unit lead to the conclusion that the calculation algorithm proposed has been chosen correctly and the 2-stage closing law of the wicket gate promoted in this case is effective in such situations.

    Lim, Brian Y.

    1991-01-01

    An existing rotary electromagnetic driver was specified to be used to deploy and restow a blackbody calibration target inside of a spacecraft infrared science instrument. However, this target was much more massive than any other previously inherited design applications. The target experienced unacceptable bounce when reaching its stops. Without any design modification, the momentum generated by the driver caused the target to bounce back to its starting position. Initially, elastomeric dampers were used between the driver and the target. However, this design could not prevent the bounce, and it compromised the positional accuracy of the calibration target. A design that successfully met all the requirements incorporated a sealed pocket 85 percent full of 0.75 mm diameter stainless steel balls in the back of the target to provide the effect of a dead-blow hammer. The energy dissipation resulting from the collision of balls in the pocket successfully dampened the excess momentum generated during the target deployment. The disastrous effects of new requirements on a design with a successful flight history, the modifications that were necessary to make the device work, and the tests performed to verify its functionality are described.

    Full Text Available The radial loading form applied to the bar is very important for reducing or avoiding the impact and vibration of the radial-forging cropping system and obtaining the high-quality cross section. A new radial stroke loading curve of the cropping hammer based on the cycloid form is proposed and the dynamic model of radial stroke loading mechanism is built. With the aim of obtaining the equivalent stiffness of the bar with V-shaped notch, which is a key parameter affecting the dynamic characteristic of radial stroke loading mechanism, the analytic model of the bar is built and the simulation experiments are designed by means of the orthogonal test method. The analytical results show that the diameter of the bar has the significant influence on the equivalent stiffness of the bar. Furthermore, the equivalent stiffness of the bar with V-shaped notch can be directly calculated according to the equivalent stiffness of smooth bar when h/d0.15. By using the cycloid stroke curve, the cropping experimental results for 45 steel bars and 20 steel bars show that the radial impact and vibration of the cropping system are decreased and the bar cross-section qualities have been significantly improved.

    Gyamfi, Alexander

    The purpose of this study was twofold. First, it identified the priority needs common to all science teachers in secondary schools in Kumasi, Ghana. Second, it investigated the relationship existing between the identified priority needs and the teacher demographic variables (type of school, teacher qualification, teaching experience, subject discipline, and sex of teacher) to be used as a basis for implementing in-service education training programs at the Science Resource Centers in Kumasi Ghana. An adapted version of the Moore Assessment Profile (MAP) survey instrument and a set of open-ended questions were used to collect data from the science teachers. The researcher handed out one hundred and fifty questionnaire packets, and all one hundred and fifty (100%) were collected within a period of six weeks. The data were analyzed using descriptive statistics, content analysis, and inferential statistics. The descriptive statistics reported the frequency of responses, and it was used to calculate the Need Index (N) of the identified needs of teachers. Sixteen top-priority needs were identified, and the needs were arranged in a hierarchical order according to the magnitude of the Need Index (0.000 ≤ N ≤ 1.000). Content analysis was used to analyze the responses to the open-ended questions. One-way analysis of variance (ANOVA) was used to test the null hypotheses of the study on each of the sixteen identified top-priority needs and the teacher demographic variables. The findings of this study were as follows: (1) The science teachers identified needs related to "more effective use of instructional materials" as a crucial area for in-service training. (2) Host and Satellite schools exhibited significant difference on procuring supplementary science books for students. Subject discipline of teachers exhibited significant differences on utilizing the library and its facilities by students, obtaining information on where to get help on effective science teaching

    Regional Teacher Training Centre (RTTC) in Skierniewice is one of 49 public, accredited institutions in Poland carrying out it statutory goals at the regional level. It has been operating since 1989 and is responsible for organizing of support of schools, institutions, networks of teachers for cooperation and self-education, organizing various forms of in-service training and disseminating examples of good practice. It also has rich experience in teaching by using modern Interactive Computer Technology (ICT) tools and e-learning platform. I present examples about teaching of Astronomical issues through teacher training both as hands on workshops as well as through e-learning. E-learning is playing an important role in organizing educational activities not only in the field of modern didactic but also in learning Science subjects. Teachers find e-learning as a very economical, easy and convenient way of learning and developing their knowledge and skills. Moreover, they are no longer afraid of using new ICT tools and programs which help them to cooperate with students effectively. Since 2011 RTTC in Skierniewice has been an organizer of many on-line in-service programs for teachers, in learning Science. Some of them are organized as blended-learning programs which allow teachers to participate first in hands on activities then continue learning on the Moodle platform. These courses include two 15 and 30-hours of Astronomical topics. Teachers have the opportunity to gain knowledge and receive materials not only about the Universe and the Solar System but also can learn to use tools like Stellarium, Celestia, WorldWide Telescope, Your Sky and other tools. E-learning modules consist of both publishing learning materials in various forms, eg. PowerPoint Presentations, Word & PDF materials, web sites, publications, working sheets as well as practical duties like participation in chats, forums, tasks, Wiki, group workshop.

    This paper reviews the experience in training Latin American professionals and scientists in the ethics of biomedical and psychosocial research at the Interdisciplinary Center for Studies in Bioethics (CIEB) of the University of Chile, aided by a grant from Fogarty International Center (FIC) – National Institutes of Health from 2002 to 2011. In these 10 years of experience, 50 trainees have completed a 12-month training combining on-line and in-person teaching and learning activities, with further support for maintaining contact via webmail and personal meetings. The network formed by faculty and former trainees has published extensively on issues relevant in the continent and has been instrumental in promoting new master level courses at different universities, drafting regulations and norms, and promoting the use of bioethical discourse in health care and research. Evaluation meetings have shown that while most trainees did benefit from the experience and contributed highly to developments at their home institutions and countries, some degree of structuring of demand for qualified personnel is needed in order to better utilize the human resources created by the program. Publications and other deliverables of trainees and faculty are presented. PMID:22754084

    Full Text Available Background and Aim: Today, work related stress has become a common and costly problem in work places that most of studies in the last 30 decades have engaged in this problem. Several reports indicate that the occupations such as nursing which have high psychological job demands and low decision latitude are very stressful. This stress can cause harmful physical and psychological effects on nurses’ health. On the other hand, job stress may result in high rates of injury, tardiness and absenteeism at work place and reduced productivity and organizational commitment leading to low quality of nursing care. Numerous studies suggested that learning new activities and skills such as communication skills is one of the best strategies against job stress .The purpose of this study was to test the effectiveness of communication Skills training in reducing work stress level among nursing personnel in rehabilitation centers. Materials and Methods: The quasi- experimental design was conducted. A sample of 48 nursing personnel participated in the study. Subjects were randomly assigned to one of two experimental or control groups. Subjects in experimental group participated in a 7- hour’s workshop, all subjects were pre and post tested (one month later for job stress and communication skills with the Karasek’s Job Content Questionnaire (JCQ and communication skills test. Results: Results revealed the following: (1 subjects in both groups after pretest were the middle level of stress and communication skills. (2 After training the experimental group scored higher on the rating of communication skills than control group and had successfully maintained their improvements for 4 weeks. (3 After training the experimental group showed lower level of stress than control group and had successfully maintained their improvements for 4 weeks. Conclusion: As a result of this research communication skills training could reduce level of stress among nursing personnel

    The Bio- Visualization, Imaging and Simulation (BioVIS) Technology Center at NASA's Ames Research Center is dedicated to developing and applying advanced visualization, computation and simulation technologies to support NASA Space Life Sciences research and the objectives of the Fundamental Biology Program. Research ranges from high resolution 3D cell imaging and structure analysis, virtual environment simulation of fine sensory-motor tasks, computational neuroscience and biophysics to biomedical/clinical applications. Computer simulation research focuses on the development of advanced computational tools for astronaut training and education. Virtual Reality (VR) and Virtual Environment (VE) simulation systems have become important training tools in many fields from flight simulation to, more recently, surgical simulation. The type and quality of training provided by these computer-based tools ranges widely, but the value of real-time VE computer simulation as a method of preparing individuals for real-world tasks is well established. Astronauts routinely use VE systems for various training tasks, including Space Shuttle landings, robot arm manipulations and extravehicular activities (space walks). Currently, there are no VE systems to train astronauts for basic and applied research experiments which are an important part of many missions. The Virtual Glovebox (VGX) is a prototype VE system for real-time physically-based simulation of the Life Sciences Glovebox where astronauts will perform many complex tasks supporting research experiments aboard the International Space Station. The VGX consists of a physical display system utilizing duel LCD projectors and circular polarization to produce a desktop-sized 3D virtual workspace. Physically-based modeling tools (Arachi Inc.) provide real-time collision detection, rigid body dynamics, physical properties and force-based controls for objects. The human-computer interface consists of two magnetic tracking devices

    Full Text Available In a previous research, a preliminary analysis on the thermal balance in different crushing systems for olive oil production was carried out. According to the previous results, in this paper the study has been extended to power consumption aspects related to the main quality features of the extracted olive oil, restricting the analysis only to the hammer crushing (Coratina cultivar, which represents the worst case. In particular, the effect of the olives delivery on the power consumption and quality of the extracted oil has been studied. The experimental trials, carried out on a laboratory plant during the 1993-94 and 1994-95 olive-oil seasons, show that, even though the diagram of power consumption has a parabolic increasing trend, the specific power decreases with the olives delivery. Anyway studying the olives hammer crushing process also from the qualitative point of view (polyphenols number, acidity, peroxide number and induction time, it is possible to define an optimal range of olives delivery values. This optimal range (140 kg/h-240 kg/h for the studied hammer crusher represents the better working solution from both the point of view of the power consumption and the quality of the extracted oil. In particular, at the beginning of the olive oil season it is necessary to work near the greatest lower bound of the optimal range just defined. With the passing of the harvesting time, the olives delivery has to be increased, reaching values near the greatest higher bound at the end of the olive oil season.

    Full Text Available Background: Chemotherapy is an important treatment for cancer, yet some of its side effects are serious and painful. Many patients with cancer suffer from psychiatric disorders that most likely result from therapeutic drugs or mental strategies to cope with their illness. Progressive muscle relaxation is one of the cost effective, self-help methods that promotes mental health in healthy participants. Thisstudy aims to determine the effect of progressive muscle relaxation training on anxiety and depression in cancer patients undergoing chemotherapy.Methods: This was a randomized, clinical study that enrolled 60 patients who received inpatient chemotherapy in the Tabriz Hematology and Oncology Research Center in 2010. We divided patients into two groups, intervention and control. All participants signed written formal consents and completed the Hospital Anxiety & Depression Scale questionnaires. Intervention group participants were trained inprogressive muscle relaxation in groups of 3-6 to enable participants to perform this technique when they were alone in the hospital and after discharge, two to three times each day. After one and three months, questionnaires were completed again by both groups and the results compared. 17th version of SPSS software was used fordata analysis.Results: After data analysis, most participants were satisfied with learning and experiencing this technique. There was no significant difference between scales in the case and control groups after one month (P>0.05. However after three months, anxiety and depression considerably improved in patients who underwent progressive muscle relaxation training (P<0.05.Conclusion: Progressive muscle relaxation training can improve anxietyand depression in cancer patients.

    Full Text Available Falls are unpredictable accidents, and the resulting injuries can be serious in the elderly, particularly those with chronic diseases. Regular exercise is recommended to prevent and treat hypertension and other chronic diseases by reducing clinical blood pressure. The “complexity index” (CI, based on multiscale entropy (MSE algorithm, has been applied in recent studies to show a person’s adaptability to intrinsic and external perturbations and widely used measure of postural sway or stability. The multivariate multiscale entropy (MMSE was advanced algorithm used to calculate the complexity index (CI values of the center of pressure (COP data. In this study, we applied the MSE & MMSE to analyze gait function of 24 elderly, chronically ill patients (44% female; 56% male; mean age, 67.56±10.70 years with either cardiovascular disease, diabetes mellitus, or osteoporosis. After a 12-week training program, postural stability measurements showed significant improvements. Our results showed beneficial effects of resistance training, which can be used to improve postural stability in the elderly and indicated that MMSE algorithms to calculate CI of the COP data were superior to the multiscale entropy (MSE algorithm to identify the sense of balance in the elderly.

    Little is known with regard to perceptions and information needs of oncology practitioners in the Middle East as they pertain to smoking cessation (SC) support for cancer patients. We sought to assess these in a regional cancer center. A survey was distributed to oncology practitioners (physicians, nurses, pharmacists, and physio- and respiratory therapists) at King Hussein Cancer Center (Amman, Jordan) for self-completion. The survey included SC-related measures of perceptions, knowledge, and practices. Descriptive statistics and cross tabulations were performed to identify misperceptions and knowledge gaps that could be corrected through continuing education. Findings revealed, among 254 practitioners surveyed, low referral rates to the SC clinic. Negative perceptions about cancer patients who smoke existed (e.g., patients needing smoking to control anxiety; patients' willpower sufficient for quitting; patients not wanting to quit and not needing more information). Substantial knowledge gaps were prevalent with regard to the detrimental outcomes associated with continued tobacco use after a cancer diagnosis and with regard to approved SC medication choices. Our results are useful in identifying topics that need to be highlighted during training and educational efforts in the region and also reinforce the need to avail such efforts in order to improve SC-related knowledge and perceptions.

    Dietary behaviors affect obesity; therefore, it seems necessary to conduct interventions to modify behavioral patterns leading to weight-gain in the family. Our goal was to determine the impact of training on women's capabilities in modifying their obesity-related dietary behaviors in Urmia, West Azerbaijan Province, Iran: applying family-centered empowerment model. A quasi-experimental study with Pretest-Posttest design was conducted on 90 over-weight/obese women in 2012 in two Health Centers of Urmia. Convenience sampling was done and the participants were randomly assigned to two 'test' and 'control' groups. Data collection was done by completing the demographic data questionnaire, the empowerment tool and dietary behavior checklist. The intervention was conducted in the form of 6 educational classes held for the 'test' group. After two months, posttest was performed by completing the forms once again. Data were analyzed with descriptive tests, t-tests, Chi2 and Fischer's test. The dietary behavior scores of the intervention group had risen from 7.4 ± 2.11 to 9.95 ± 2.41 (Pempowerment model in this study was proven effective in women. Hence it is advised to consider it in behavior changing interventions to promote the health of the family and community.

    Full Text Available Appropriate tool-object pairing is a natural part of our lives. When preparing to stir coffee, we know that a hammer is useful for some tasks but that it is not appropriate in this behavioral context. The neural correlates of this context-tool pairing process remain unclear. In the current work, we used event-related electroencephalography (EEG and functional magnetic resonance imaging (fMRI to determine neural correlates for differentiating contextually correct and incorrect tool use. Subjects were shown images depicting correct (e.g., spoon used to stir coffee or incorrect (e.g., hammer used to stir coffee tool use. We identified distinct regional and temporal activations for identifying incorrect versus correct tool use. The posterior cingulate, insula and superior temporal gyrus preferentially differentiated incorrect tool-object usage, while occipital, parietal and frontal areas were active in identifying correct tool use. Source localized EEG analysis confirmed the fMRI data and showed phases of activation, where incorrect tool-use activation (0 - 200 ms preceded occipitotemporal activation for correct tool use (300 - 400 ms. This work extends our previous findings to better identify the neural substrate for contextual evaluation of tool use, and may contribute to our understanding of neurological disorders resulting in tool-use deficits.

    The purpose of this study was to compare various effects on the hand-arm system of vibration exposure from a chipping hammer and a grinder with the same frequency weighted acceleration. Grip and push forces were measured and monitored during the exposure. The various effects were: muscle activity (measured with surface electrodes), discomfort ratings for different parts of the hand-arm system (made during and after exposure), and vibration perception threshold (for 10 minutes before and 10 minutes after the exposure). No increase in muscle activity due to exposure to vibration was found in the hand muscle studied. In the forearm, conversely, there was an increase in both muscle studied. For the upper arm the muscle activity only increased when exposed to impact vibration. Subjective ratings in the hand and shift in vibration perception threshold were effected more by the grinder than the hammer exposure. These results show that the reaction of the hand-arm system to vibration varies with frequency quantitatively as well as qualitatively. They do not support the notion that one single frequency weighted curve would be valid for the different health effects of hand-arm vibration (vascular, musculoskeletal, neurological, and psychophysiological).

    Cirrhosis is a chronic and progressive disease that causes various complications for patients due to disturbance of the liver's usual function. Self-efficacy refers to an individual's belief in one's ability to perform the necessary behaviors to achieve one's goals. Self-management is also an important criterion for long-term change in behavior. The present study aimed to investigate the effect of self-management training on self-efficacy of patients suffering from liver cirrhosis. This randomized controlled clinical trial was conducted on 74 patients with liver cirrhosis randomly assigned to an intervention (receiving self-management training) and a control group (routine care) from 2012 to 2013. The data were collected in the transplantation center affiliated to Shiraz University of Medical Sciences. Self-management training was performed in six 90-minute sessions twice a week. Besides, the intervention group was followed up for a month via telephone. Levo self-efficacy questionnaire was filled out by the patients before, immediately after, and one month after the intervention. Then, the data were entered into the SPSS statistical software (v. 16) and analyzed using independent t-test, Chi-square test, and repeated measures ANOVA. At the beginning of the study, no statistically significant difference was found between the two groups regarding self-efficacy (P=0.18). However, the total score of the questionnaire and those of all its dimensions significantly improved in the intervention group immediately and one month after training self-management skills (Pself-efficacy was 102.24±7.79 and 76.78±9.49 in the intervention and control groups, respectively. On the other hand, no statistically significant difference was observed in the control group's self-efficacy immediately and one month after the intervention (P=0.6). The results showed that the self-management program resulted in improvement of self-efficacy in the patients with liver cirrhosis. Therefore, this

    product (Arm & Hammer Free & Clear) and other nonirritant controls. In the Wrist Band Wear test, exposure to laundered fabrics under exaggerated conditions gave similar results for the test and control products, with no objective signs of skin irritation, and no self-reported persistent adverse sensory effects. Very mild, transient and isolated sensory effects were noted in daily diaries by a small proportion of subjects, and were similar for the test and control products. The Safety In-Use tests evaluated 4-week exposure to product and laundered fabrics under realistic use conditions. There were no clinically objective signs of skin irritation, and reports of transitory, mild sensory effects were minimal and similar for the test and controls. A comprehensive skin safety program on a lightly scented sensitive skin laundry formulation (i.e. Arm & Hammer™ Sensitive Skin plus Skin-Friendly Fresh Scent) conducted among panels of self-assessed sensitive skin subjects demonstrated that the presence of a light fragrance did not adversely impact skin compatibility in any of the testing protocols when the product was compared to a similar product with no fragrance. The lightly fragranced product demonstrated overall skin compatibility and mildness when tested in a self-assessed sensitive skin population, and compared favorably to currently marketed sensitive skin products.

    This paper reports the preliminary progress in the CFD simulation of the reverse water-hammer induced by the collapse of a draft-tube cavity in a model pump-turbine during the runaway process. Firstly, the Fluent customized 1D-3D coupling model for hydraulic transients and the Schnerr & Sauer cavitation model for cavity development are introduced. Then, the methods are validated by simulating the benchmark reverse water-hammer in a long pipe caused by a valve instant closure. The simulated head history at the valve agrees well with the measured data in literature. After that, the more complicated reverse water-hammer in the draft-tube of a runaway model pump-turbine, which is installed in a model pumped-storage power plant, is simulated. The dynamic processes of a vapor cavity, from generation, expansion, shrink to collapse, are shown. After the cavity collapsed, a sudden increase of pressure can be evidently observed. The process is featured by a locally expending and collapsing vapor cavity that is around the runner cone, which is different from the conventional recognition of violent water- column separation. This work reveals the possibility for simulating the reverse water-hammer phenomenon in turbines by 3D CFD.

  14. First attempt to study rock glaciers in New Zealand using the Schmidt-hammer - framework and preliminary results

    2016-04-01

    Although not uncommon within the dryer eastern parts of the Southern Alps, New Zealand, comparatively few previous studies have previously focused on rock glacier dynamics and spatial distribution. Neither investigations of their chronological constraints nor any studies on actual rock glacier velocities have yet been carried out. Rock glaciers and periglacial processes still largely constitute a largely unexplored albeit potentially valuable field of research in the Southern Alps. The high-altitude valley head of Irishman Stream in the Ben Ohau Range between Lakes Ohau and Pukaki, roughly 30 km southeast of the Main Divide, contains a few morphologically intact rock glaciers and some appear to be active features (Sattler et al. 2016). Previous work focusing on the Late-glacial and early Holocene moraines in the valley head below the rock glaciers (Kaplan et al. 2010) provided 10Be-ages that could be utilised as fixed points for SHD (Schmidt-hammer exposure-age dating). Apart from detailed Schmidt-hammer sampling on the Late-glacial and early Holocene moraines, two altitudinal transects from the toe to their apex have been measured in detail on selected rock glaciers. On each of the multiple ridges of the rock glacier surface three sites of 50 boulders have been sampled with one impact each by the hammer (an N-type electronic SilverSchmidt by Proceq). Apart from getting some age constraints of these periglacial features in comparison to the well-dated moraines, the Schmidt-hammer measurements also had the aim to provide some insight into their genetic development resulting in a quite complex morphology of the rock glaciers and partial interaction with some of the moraines. Both altitudinal transects reveal a clear and continuous trend of increasing means (i.e. less weathered/younger exposure ages) towards their apex. The values for the individual ridges show, however, a transitional character with adjacent ridges albeit the abovementioned trend not statistically

    2010-01-01

    Full Text Available This paper presents two examples of exploitation of water energy that can be used in the irrigation field. First of theseexamples is the hydraulic transformer type A. Barglazan used for irrigation, pumped water is taken directly from theriver’s well, using a hydraulic pump which simultaneously carried out a double transformation in this way: hydraulicenergy into mechanic energy and mechanical energy into hydraulic energy. Technology preparation and devices designwas done in record time, seeing that this constructive solution is more robust, reliable and with improved energyperformance versus the laboratory prototype. The experimental research which was made at 1:1 scale proved theirgood function over time. Another example is the hydraulic hammer (hydraulic pump that uses low-head energy topump water, with a global efficiency of about 10 - 50%. Currently, the new situation of private ownership of landprovides conditions for new pumping microstations to be made where irrigation is necessary and optimal hydrauliclocations exist.

    The lesions of the skull following perforating traumas can create complex fractures. The blunt traumas can, according to the swiftness and the shape of the object used, create a depressed fracture. The authors describe through two clinical cases the lesional characteristic of the blunt traumas, perforating the skull using a hammer. In both cases the cranial lesions were very typical: they were geometrical, square shaped, of the same size than the tool (head and tip of the hammer). On the outer table of the skull, the edges of the wounds were sharp and regular. On the inner table, the edges of the wounds were beveled and irregular. The bony penetration in the depressed fracture results from a rupture of the outer table of the bone under tension, in periphery, by the bend of the bone to the impact (outbending) and then, from the inner table with comminuted bony fragmentation. Breeding on the fractures of the size and the shape of the blunt objects used is inconstant and differs, that it is the objects of flat surface or wide in opposition to those of small surface area. Fractures morphologies depend on one hand on these extrinsic factors and on the other hand, of intrinsic factors (structure of the bone). To identify them, we had previously conducted experimental work on cranial bone samples. The bone was submitted to a device for three-point bending. This work had shown properties of thickness and stiffness of the various areas of the vault. Our cases are consistent with these results and illustrate the variability of bone lesions according to region and mode of use of blunt weapons. Many studies have identified criteria for identification of the weapons and the assistance of digital and biomechanical models will be an invaluable contribution with this aim in the future.

    Full Text Available It is the basic requirement of maritime safety education to guarantee the safety of teaching operation while training the crew's occupation safety capability. Marine Training Center of Shanghai Maritime University has undertaken the practical teaching of "marine survival" for many years and come up with the whole safety procedures of training. Based on the requirements of SOLAS convention and regulations of STCW over crew training, this paper introduces the safety allocation, utilization and maintenance of teaching equipments. Through the investigation of the safety situation of students' practical operation, the safety teaching method named "four in one" has been put forward, which includes the pre-teaching safety precaution, the whole monitor during the teaching process, the post-teaching summary evaluation, and the reset and standby of teaching facilities. Finally, during the learning and training of "marine survival", crews and students are called on to place priority on personal safety rather than acquisition of knowledge and skills. Only in this way can they be capable of self-protection and protection of others in the career of seafaring.

    2017-01-01

    Full Text Available The research presented in the article conforms to the severe accident that took place at the Three Mail Island nuclear power plant in the USA. The research is focused on improving the reliability of the pressure compensator that is an important equipment of the primary circuit. In order to simulate such a situation, the stand has been developed to simulate the design of the pressurizer of the PWR-440 reactor, in particular an elliptical shape of the upper lid which has a steam outlet pipe at the top of the construction that creates conditions for occurrence of such water hammers. For the experiments, an installation has been created that makes it possible to measure and record the water hammering that occur when the tanks are filled. Measurement of the amplitude of the water hammering was carried out by a specially developed piezoelectric sensor, and the registration – by a light-beam oscilloscope. The technique of carrying out the experiment is described and the results of an experimental study of the water hammers arising when the vessels are completely filled are presented. Quantitative data were obtained on the amplitudes of the hydraulic impacts depending on the rate of filling of the vessel and the diameter of the outlet, the maximum pressure of the hydraulic shock was 7–9 atm. Comparison of calculated and experimental data has been performed. The allowable discrepancy is explained by the calculated value of the system stiffness coefficient, which did not take into account the presence of welded seams in the tank that imparts the system with additional rigidity. The calculated relationships are obtained, that make it possible to estimate the amplitudes of the water hammers through the acceleration of the water level in front of the outlet from a vessel with an elliptical bottom. The possibility of a water hammer in the pressure compensator is demonstrated by experiment and by theoretical calculations. Based on the experimental data, a

    Underground Research Laboratories (URLs) to develop and demonstrate technologies for the safe geologic disposal of radioactive wastes have been established for national purposes by several Member States of the International Atomic Energy Agency (IAEA). Under the auspices of the IAEA, nationally developed URLs and associated research institutions are being offered for use by other nations. These facilities form a Network of Centers of Excellence for training in and development of waste disposal technologies. Experience gained in the operation of the facilities, and through associated experimentation and demonstrations, will be transferred to participating Member States through hands-on work at the facilities. The Network consists of Network Members and Network Participants who share co-operative activities. Network Members are owners of facilities who have offered them to be part of the Network. At this time there are eight Members consisting of six underground facilities, a laboratory, and a university. Network Participants can potentially come from any interested IAEA Member State having spent nuclear fuel for disposal, with or without an established program for geologic disposal. There are presently about 15 Network Participants. A significant Network activity beginning in 2003 will be a Coordinated Research Project (CRP) on characterization and evaluation of swelling clays for use in engineered barrier systems of geologic repositories. At the end of this project, every involved Member State should be able to identify and characterize a swelling clay that is suitable for use in a geologic repository. As the Network grows, additional CRPs to be carried out in the Underground Research Facilities of the Network Members will be defined.

    Full Text Available Background: Cutaneous leishmaniasis (CL is a major health problem in many parts of Iran, although diagnosis of CL especially in the endemic area is easy, but treatment and management of the disease is a global dilemma. Diagno­sis of CL in non-endemic area is not as simple as in endemic foci. In this study, the status and the proportions of CL induced by Leishmania major and L. tropica among CL suspected patients referred to the Center for Research and Training in Skin Diseases and Leprosy, (CRTSDL during 2008 to 2011 are described.Methods: CL patients with suspected lesions were clinically examined. History of trip to zoonotic CL and/or anthroponotic CL endemic areas and the characte­ristics of their lesion(s were recorded. Diagnosis of the lesion was done using direct smear microscopy, culture and conventional polymerase chain reaction (PCR.Results: A total of 404 (M=256, F=148 patients with 776 lesions were re­cruited and parasitologically examined. The results showed that 255 of the pa­tients with 613 lesions; patients with lesion(s induced by L. major=147 (M=63, 43%, F=84, 57% and lesion(s induced by L. tropica=108 (M=35, 32%, F=73, 68%. History of travel to endemic area was not always correlated with isolated Leishmania species.Conclusion: Although travel history to endemic area is an important factor to be considered for diagnosis, but parasitological confirmation is necessary initia­tion of treatment.

    Full Text Available Sistem jaringan perpipaan merupakan komponen penting dalam menunjang produksi maupun distribusi pada sektor industri. Jaringan perpipaan mengalami beberapa fenomena seperti distribusi fluida dan water hammer. Water hammer sering terjadi di daerah discharge pompa pada saat pengoperasian pompa maupun pada saat kegagalan operasi pompa. Beberapa cara untuk mengurangi dampak water hammer adalah dengan menambahkan flywheel ataupun gas accumulator pada jaringan perpipaan. Lonjakan tekanan serta aliran balik yang terjadi akibat fenomena water hammer akan dilawan oleh putaran impeller  pompa yang dibebani oleh flywheel dan akan memperlambat lonjakan tekanan dalam pipa dan tekanan yang berlebih akan dibuang ke gas accumulator sehingga tekanan dalam pipa berangsur stabil. Pemodelan sistem perpipaan dilakukan dengan menggunakan software sistem perpipaan. Pemodelan yang disimulasikan merupakan sistem perpipaan dengan rangkaian pompa paralel yang dilengkapi flywheel pada instalasi pompa dan divariasikan dengan penambahan gas accumulator sebagai sistem proteksi water hammer. Analisa yang dilakukan adalah untuk mempelajari fenomena water hammer pada saat kondisi ekstrim yakni ketika dua pompa operasi mati dan juga ketika empat pompa operasi mati, untuk melihat pengaruh variasi ukuran flywheel terhadap fluktuasi tekanan yang terjadi. Ukuran flywheel divariasikan yakni ukuran diameter luar 1100mm, 1200mm dan 1300mm dengan tebal masing-masing 300mm, 400mm dan 500mm. Hasil simulasi menunjukkan bahwa pada sistem perpipaan tanpa menggunakan gas accumulator, tekanan maksimum yang terjadi pada discharge pompa mencapai 19,807 bar dari kondisi tekanan kerjanya 5,6 bar. Variasi ukuran flywheel memberi dampak pada perlambatan terjadinya lonjakan tekanan, semakin besar ukuran flywheel akan menunda terjadinya lonjakan tekanan akibat water hammer. Dan penambahan gas accumulator berperan dalam meredam serta mempersingkat waktu terjadinya lonjakan tekanan, sehingga fluktuasi

    2013-04-01

    Full Text Available Article describes simulation of unsteady flow during water hammer with two programs, which use different numerical approaches to solve ordinary one dimensional differential equations describing the dynamics of hydraulic elements and pipes. First one is Matlab-Simulink-SimHydraulics, which is a commercial software developed to solve the dynamics of general hydraulic systems. It defines them with block elements. The other software is called HYDRA and it is based on the Lax-Wendrff numerical method, which serves as a tool to solve the momentum and continuity equations. This program was developed in Matlab by Brno University of Technology. Experimental measurements were performed on a simple test rig, which consists of an elastic pipe with strong damping connecting two reservoirs. Water hammer is induced with fast closing the valve. Physical properties of liquid and pipe elasticity parameters were considered in both simulations, which are in very good agreement and differences in comparison with experimental data are minimal.

    Base-line and long-term monitoring of water resources of the National Guard Training Center at Fort Indiantown Gap in south-central Pennsylvania began in 2002. Results of continuous monitoring of streamflow and turbidity and monthly and stormflow water-quality samples from two continuous-record long-term stream sites, periodic collection of water-quality samples from five miscellaneous stream sites, and annual collection of biological data from 2002 to 2005 at 27 sites are discussed. In addition, results from a stream-geomorphic analysis and classification and a regional groundwater-flow model are included. Streamflow at the facility was above normal for the 2003 through 2005 water years and extremely high-flow events occurred in 2003 and in 2004. Water-quality samples were analyzed for nutrients, sediments, metals, major ions, pesticides, volatile and semi-volatile organic compounds, and explosives. Results indicated no exceedances for any constituent (except iron) above the primary and secondary drinking-water standards or health-advisory levels set by the U.S. Environmental Protection Agency. Iron concentrations were naturally elevated in the groundwater within the watershed because of bedrock lithology. The majority of the constituents were at or below the method detection limit. Sediment loads were dominated by precipitation due to the remnants of Hurricane Ivan in September 2004. More than 60 percent of the sediment load measured during the entire study was transported past the streamgage in just 2 days during that event. Habitat and aquatic-invertebrate data were collected in the summers of 2002-05, and fish data were collected in 2004. Although 2002 was a drought year, 2003-05 were above-normal flow years. Results indicated a wide diversity in invertebrates, good numbers of taxa (distinct organisms), and on the basis of a combination of metrics, the majority of the 27 sites indicated no or slight impairment. Fish-metric data from 25 sites indicated results

  16. Constraints to connecting children with nature--Survey of U.S. Fish and Wildlife Service employees sponsored by the National Conservation Training Center, Division of Education Outreach

    Ratz, Joan M.; Schuster, Rudy M.

    2011-01-01

    The U.S. Fish and Wildlife Service (FWS) names "connecting people with nature" as one of its top six priorities in the online Service Employee Pocket Guide. The National Conservation Training Center (NCTC) took the initiative to identify issues that impede greater progress in addressing constraints to connecting children with nature. The Division of Education Outreach at NCTC formed a working relation with the Policy Analysis and Science Assistance branch of the U.S. Geological Survey to conduct a study on these issues. To meet the objectives of the study, a survey of a sample of FWS employees was conducted. This report includes the description of how the survey was developed and administered, how the data were analyzed, and a discussion of the survey results. The survey was developed based on published literature and incorporated input from two working groups of professionals focused on the issue of connecting children with nature. Although the objective as stated by the FWS is to connect people with nature, the survey primarily focused on connecting children, rather than all people, with nature. The four primary concepts included on the survey were interpretation of how the FWS defined "connection" as part of its mission, perceived success with outreach, constraints to connecting children with nature, and importance of connecting children with nature. The survey was conducted online using KeySurvey© software. The survey was sent to 604 FWS employees. Responses were received from 320 employees. The respondents represented diversity in regions, tenure, wage/grade level, job series, supervisory status, and involvement with education and outreach activities. The key findings of the survey are as follows: * FWS employees believe they as individuals and the agency are successful now and will be more successful in the future in connecting children with nature. * FWS employees believe that there are many outcomes that are relevant to the FWS objective to connect people

    Full Text Available The study was conducted in Hammer district, Southern Ethiopia, to provide empirical evidence on economic contribution to local livelihoods and households dependency on dry forest products. One agropastoral and two pastoral kebeles were purposively selected, and data was collected through household survey, group discussions, market assessments, and field observation. A total of 164 households, selected based on a random sampling procedure, were interviewed using structured questionnaire. The study found that income from forest products contributes 21.4% of the total annual household income. The major dry forest products include honey, fuel wood, gum and resin, and crafts and construction materials, contributing 49%, 39%, 6%, and 6% of the forest income, respectively. Households of the pastoral site earned more forest income and were relatively more dependent on forest products income than those in the agropastoral study site. Significant variation was also found among income groups: households with higher total annual income obtain more forest income than those with lower income, but they are relatively less dependent on forest products than the lower counterpart. Besides, various socioeconomic and contextual factors were found to influence forest income and dependency. The findings of the study provide valuable information up on which important implications for dry land forest development and management strategies can be drawn.

    This paper presents a sub-harmonic mixer at 340 GHz based on anti-parallel Schottky diodes (SBDs). Intrinsic resonances in low-pass hammer-head filter have been adopted to enhance the isolation for different harmonic components, while greatly minimizing the transmission loss. The application of new DC grounding structure, impedance matching structure, and suspended micro-strip mitigates the negative influences of fabrication errors from metal cavity, quartz substrate, and micro-assembly. An improved lumped element equivalent circuit model of SBDs guarantees the accuracy of simulation, which takes current-voltage (I/V) behavior, capacitance-voltage (C/V) behavior, carrier velocity saturation, DC series resistor, plasma resonance, skin effect, and four kinds of noise generation mechanisms into consideration thoroughly. The measurement indicates that with local oscillating signal of 2 mW, the lowest double sideband conversion loss is 5.5 dB at 339 GHz; the corresponding DSB noise temperature is 757 K. The 3 dB bandwidth of conversion loss is 50 GHz from 317 to 367 GHz.

  19. Analysis of Water Hammer with Different Closing Valve Laws on Transient Flow of Hydrogen-Natural Gas Mixture

    Full Text Available Water hammer on transient flow of hydrogen-natural gas mixture in a horizontal pipeline is analysed to determine the relationship between pressure waves and different modes of closing and opening of valves. Four types of laws applicable to closing valve, namely, instantaneous, linear, concave, and convex laws, are considered. These closure laws describe the speed variation of the hydrogen-natural gas mixture as the valve is closing. The numerical solution is obtained using the reduced order modelling technique. The results show that changes in the pressure wave profile and amplitude depend on the type of closing laws, valve closure times, and the number of polygonal segments in the closing function. The pressure wave profile varies from square to triangular and trapezoidal shape depending on the type of closing laws, while the amplitude of pressure waves reduces as the closing time is reduced and the numbers of polygonal segments are increased. The instantaneous and convex closing laws give rise to minimum and maximum pressure, respectively.

    To evaluate feasibility of an exercise intervention consisting of high-intensity interval endurance and strength training in breast cancer patients. Twenty-six women with nonmetastatic breast cancer were consecutively assigned to the exercise intervention- (n= 15, mean age 51.9 ± 9.8 years) and the control group (n = 11, mean age 56.9 ± 7.0 years). Cardiopulmonary exercise testing that included lactate sampling, one-repetition maximum tests and a HADS-D questionnaire were used to monitor patients both before and after a supervised six weeks period of either combined high-intensity interval endurance and strength training (intervention group, twice a week) or leisure training (control group). Contrarily to the control group, endurance (mean change of VO2, peak 12.0 ± 13.0%) and strength performance (mean change of cumulative load 25.9 ± 11.2%) and quality of life increased in the intervention group. No training-related adverse events were observed. Our guided exercise intervention could be used effectively for initiation and improvement of performance capacity and quality of life in breast cancer patients in a relatively short time. This might be especially attractive during medical treatment. Long-term effects have to be evaluated in randomized controlled studies also with a longer follow-up. Implications for Rehabilitation High-intensity interval training allows improvement of aerobic capacity within a comparable short time. Standard leisure training in breast cancer patients is rather suitable for the maintenance of performance capacity and quality of life. Guided high-intensity interval training combined with strength training can be used effectively for the improvement of endurance and strength capacity and also quality of life. After exclusion of contraindications, guided adjuvant high-intensity interval training combined with strength training can be safely used in breast cancer patients.

    Environmental contamination with radioactive materials caused by the Fukushima Dai-ichi Nuclear Power Plant (NPP) accident in 2011 raised a serious health concern among residents in Japan, and the demand for radiation experts who can handle the radiation-associated problems has increased. The Human Resources Development Center (HRDC) of the National Institute of for Quantum and Radiological Science and Technology in Japan has offered a variety of training programs covering a wide range of technologies associated with radiation since 1959. In this study, the time-course change in the number and age of the applicants for training programs regularly scheduled at HRDC were analyzed to characterize the demand after the NPP accident. The results suggested that the demand for the training of industrial radiation experts elevated sharply after the NPP accident followed by a prompt decrease, and that young people were likely stimulated to learn the basics of radiation. The demand for the training of medical radiation experts was kept high regardless of the NPP accident. The demand for the training of radiation emergency experts fluctuated apparently with three components: a terminating demand after the criticality accident that occurred in 1999, an urgent demand for handling of the NPP accident, and a sustained demand from local governments that undertook reinforcement of their nuclear disaster prevention program. The demand for the training of school students appeared to be increasing after the NPP accident. It could be foreseen that the demand for training programs targeting young people and medical radiation experts would be elevated in future.

  7. Visual persuasion and politics: ideology and symbols of the totalitarian regimes'--case study: hammer and sickle.

    Unlike all other autocracies, authoritarian regimes are, as the ultimate form of authoritarianism, a distinct phenomenon of the modern era. Caused by the crisis of liberal democracy and industrial capitalism of the early twentieth century, and led by radical populist political movements/parties and their leaders, they established themselves as the regimes which marked one of the greatest degrees of unfreedom. The article analyzes the specific sociostructural, sociocultural and sociopsychological aspects of the formation of totalitarian regimes (particularly communism), as well as their political system, ideological foundations and modus operandi. In doing so, it particularly emphasizes the dissolution of civil society and its substitution by a political society as a key structural determinant, authoritarianism and fear as a sociopsychological basis, and repression as the functional basis of operation for totalitarian regimes. In that context, it analyzes the political, anthropological and visual aspects of the symbols of totalitarian regimes, their archetypal (mythological, religious, ethnic, cultural, historical) meaning, and explains their function (political, anthropological, sociocultural, and sociopsychological) in the development and preservation of totalitarian regimes. Using the example of the hammer and sickle, a typical symbol of communism, it shows a substantial and communicational (particularly visual) dimension of symbol, by breakdown by the elements of semiotics (signum, designatum, interpretant) and its sub-disciplines (semantics, pragmatics, sintactics). On this basis, it tries to show the decisive power of political symbols over the political perceptions and political behavior of individuals and entire social groups, i.e. their manipulative power by meanings assigned to them by totalitarian authorities and forms of their communication, with the goal of preserving the totalitarian regime.

    Two interrelated studies are reported. One reports the results of a questionnaire interview with a reference group of 51 general practitioners. The respondents express a considerable dissatisfaction with their previous medical training as it concerns their knowledge of the psychosomatic medical paradigm. The other study evaluates the effects of a 5-year education program concerning psychodynamic theories and an integrative psychosomatic approach to treatment. Six general practitioners participated in this educational program, which included both theoretical seminars and practical training in psychotherapy (under supervision) with patients suffering from chronic idiopathic pain syndrome. All the participants reported developing substantial skill in treating such patients and in handling other kinds of patients with multifactorial etiology of symptoms. The participants of the training program did not initially differ from the larger reference group as to the previous knowledge and practice in integrative psychosomatic medicine, and it may be concluded that many physicians would profit from such post-graduate training. The self-reports of all these experienced physicians also indicate that there is too little theory and practice of the psychesoma interaction in the basic medical education.

    Abstract Purpose: To determine the community‐based participatory research (CBPR) training interests and needs of researchers interested in CBPR to inform efforts to build infrastructure for conducting community‐engaged research. Method: A 20‐item survey was completed by 127 academic health researchers at Harvard Medical School, Harvard School of Public Health, and Harvard affiliated hospitals. Results: Slightly more than half of the participants reported current or prior experience with CBPR (58 %). Across all levels of academic involvement, approximately half of the participants with CBPR experience reported lacking skills in research methods and dissemination, with even fewer reporting skills in training of community partners. Regardless of prior CBPR experience, about half of the respondents reported having training needs in funding, partnership development, evaluation, and dissemination of CBPR projects. Among those with CBPR experience, more than one‐third of the participants wanted a mentor in CBPR; however only 19 % were willing to act as a mentor. Conclusions: Despite having experience with CBPR, many respondents did not have the comprehensive package of CBPR skills, reporting a need for training in a variety of CBPR skill sets. Further, the apparent mismatch between the need for mentors and availability in this sample suggests an important area for development. Clin Trans Sci 2012; Volume #: 1–5 PMID:22686211

    The present study investigated the exposure of teenagers, adults, and students to PM1, PM2.5, PM4, PM10, particle number concentration at two sport facilities of Nazarbayev University including Gymnastics Hall and Multi-purpose Hall. Measurements were conducted during variety of sport training sessions including soccer, basketball, volleyball, Mixed Martial Arts (MMA), boxing, table tennis, etc. A low-cost instrument, Dylos was employed to compare its performance against two TSI instruments. In overall, the Dylos showed acceptable peaks when the source of particle resuspension was present. However, no correlation was observed between Dylos data and Dusttrak fine and coarse particle data. The average PM2,5 and PM10 concentrations were found to be below the WHO limits. The number of participants during the training sessions and sports involving balls including basketball, soccer and volleyball were the two factors responsible for the observed increased particle resuspension.

    Individuals with a psychotic disorder are at an increased risk of becoming victim of a crime or other forms of aggression. Research has revealed several possible risk factors (e.g. impaired social cognition, aggression regulation problems, assertiveness, self-stigma, self-esteem) for victimization in patients with a psychotic disorder. To address these risk factors and prevent victimization, we developed a body-oriented resilience training with elements of kickboxing: BEATVIC. The present study aims to evaluate the effectiveness of the intervention. Seven mental health institutions in the Netherlands will participate in this study. Participants will be randomly assigned to either the BEATVIC training or the control condition: social activation. Follow-ups are at 6, 18 and 30 months. Short term effects on risk factors for victimization will be examined, since these are direct targets of the intervention and are thought to be mediators of victimization, the primary outcome of the intervention. The effect on victimization will be investigated at follow-up. In a subgroup of patients, fMRI scans will be made before and after the intervention period in order to assess potential neural changes associated with the effects of the training. This study is the first to examine the effectiveness of an intervention targeted at victimization in psychosis. Methodological issues of the study are addressed in the discussion of this paper.

    NASA exploration missions are increasingly including sampling tasks but with the growth in engineering experience (particularly, Phoenix Scout and MSL) it is now very much recognized that planetary drilling poses many challenges. The difficulties grow significantly with the hardness of sampled material, the depth of drilling and the harshness of the environmental conditions. To address the requirements for samplers that could be operated at the conditions of the various bodies in the solar system, a number of piezoelectric actuated drills and corers were developed by the Advanced Technologies Group of JPL. The basic configuration that was conceived in 1998 is known as the Ultrasonic/Sonic Driller/Corer (USDC), and it operates as a percussive mechanism. This drill requires as low preload as 10N (important for operation at low gravity) allowing to operate with as low-mass device as 400g, use an average power as low as 2- 3W and drill rocks as hard as basalt. A key feature of this drilling mechanism is the use of a free-mass to convert the ultrasonic vibrations generated by piezoelectric stack to sonic impacts on the bit. Using the versatile capabilities f the USDC led to the development of many configurations and device sizes. Significant improvement of the penetration rate was achieved by augmenting the hammering action by rotation and use of a fluted bit to remove cuttings. To reach meters deep in ice a wireline drill was developed called the Ultrasonic/Sonic Gopher and it was demonstrated in 2005 to penetrate about 2-m deep at Antarctica. Jointly with Honeybee Robotics, this mechanism is currently being modified to incorporate rotation and inchworm operation forming Auto-Gopher to reach meters deep in rocks. To take advantage of the ability of piezoelectric actuators to operate over a wide temperatures range, piezoelectric actuated drills were developed and demonstrated to operate at as cold as -200oC and as hot as 500oC. In this paper, the developed mechanisms

    In connection with the 2002 amendment to the German Atomic Energy Act, the topics of generational change and maintenance of competence grew in importance and necessitated new solution approaches. To this end, various activities were launched, with the aim of conducting conceptual analyses of these topics. Examples include the 'National Competence Network for Nuclear Technology' (Nationaler Kompetenzverbund fuer Kerntechnik), various networks established by colleges and universities, the 'Knowledge Management for the Maintenance and Transfer of Competence in Reactor Safety' (Wissensmanagement zum Kompetenzerhalt und -transfer in der Reaktorsicherheit) workshop held in 2001 in Garching near Munich (Germany) and the 'Ad-hoc Workgroup on the Maintenance of Competence' (Ad-hoc-Arbeitskreis Kompetenzerhalt) of the VdTUeV. The nuclear technology departments of the TUeV Nord Group were aware of te challenges associated with the generational change early on. By establishing the 'Nuclear Technology Training Center' (Ausbildungszentrum fuer Kerntechnik, AfK), the TUeV Nord Group intended to ensure the required knowledge transfer during the generational change as well as maintain the renowned high qualification as regards the subject of nuclear technology and thus continue to provide - in the sense of social responsibility - crucial contribution to the long-term safety of nuclear plants. Four years have passed since the training center held the first courses in the fall of 2002. Up to now, more than 350 participants have been trained in the courses conducted by the AfK. In the opinion of the TUeV Nord Group, the activities of the AfK have laid the foundation for a successful change of generations within the group's nuclear technology organizations. (orig.)

    Neurons have been found in the primate brain that respond to objects in specific locations in hand-centered coordinates. A key theoretical challenge is to explain how such hand-centered neuronal responses may develop through visual experience. In this paper we show how hand-centered visual receptive fields can develop using an artificial neural network model, VisNet, of the primate visual system when driven by gaze changes recorded from human test subjects as they completed a jigsaw. A camera mounted on the head captured images of the hand and jigsaw, while eye movements were recorded using an eye-tracking device. This combination of data allowed us to reconstruct the retinal images seen as humans undertook the jigsaw task. These retinal images were then fed into the neural network model during self-organization of its synaptic connectivity using a biologically plausible trace learning rule. A trace learning mechanism encourages neurons in the model to learn to respond to input images that tend to occur in close temporal proximity. In the data recorded from human subjects, we found that the participant's gaze often shifted through a sequence of locations around a fixed spatial configuration of the hand and one of the jigsaw pieces. In this case, trace learning should bind these retinal images together onto the same subset of output neurons. The simulation results consequently confirmed that some cells learned to respond selectively to the hand and a jigsaw piece in a fixed spatial configuration across different retinal views.

  4. Changing the Learning Environment in the College of Engineering and Applied Science: The impact of Educational Training on Future Faculty and Student- Centered Pedagogy on Undergraduate Students

    Gaskins, Whitney

    Over the past 20 years there have been many changes to the primary and secondary educational system that have impacted students, teachers, and post-secondary institutions across the United States of America. One of the most important is the large number of standardized tests students are required to take to show adequate performance in school. Students think differently because they are taught differently due to this focus on standardized testing, thus changing the skill sets students acquire in secondary school. This presents a critical problem for colleges and universities, as they now are using practices for and have expectations of these students that are unrealistic for the changing times. High dropout rates in the College of Engineering have been attributed to the cultural atmosphere of the institution. Students have reported a low sense of belonging and low relatability to course material. This study developed a "preparing the future" faculty program that gave graduate students at the University of Cincinnati a unique training experience that helped them understand the students they will educate. They received educational training, developed from a future educator's curriculum that covered classroom management, standards, and pedagogy. Graduate students who participated in the training program reported increases in self-efficacy and student understanding. To reduce negative experiences and increase motivation, Challenge Based Learning (CBL) was introduced in an undergraduate Basic Electric Circuits (BEC) course. CBL is a structured model for course content with a foundation in problem-based learning. CBL offers general concepts from which students derive the challenges they will address. Results show an improved classroom experience for students who were taught with CBL.

  5. Consideration of geomorphological uncertainties with terrestrial cosmogenic nuclide dating (TCND): combining Schmidt-hammer and 10Be dating, Southern Alps, New Zealand

    "by vision". Especially in regions like the Southern Alps affected of considerable neo-tectonic activity and paraglacial erosion, post-depositional movement of any boulders on moraine ridges cannot be excluded a priori. On base on these considerations, an attempt to combine TCND with Schmidt-hammer measurements for the dating of Holocene moraines and the reconstruction of a regional glacier chronology has been developed (Winkler 2009). Cosmogenic 10Be dating delivers ‘absolute' ages for the exposure of boulder surfaces, i.e. the same surface tested with the Schmidt-hammer relative-age dating technique. Therefore, Schmidt-hammer measurements can successfully endorse the selection of representative boulders for TCND and effectively avoid sampling boulders that have been exposed to post-depositional movement (e.g. rotation). Additionally, the number of boulders sampled for TCND can be reduced, positive in the light of economic and conservational considerations. Results from the application of this combined ‘multi-proxy-approach' at a number of individual glaciers in Westland/Tai Poutini and Mt Cook/Aoraki National Parks of the Southern Alps proof its potential. At least three ‘Little Ice Age'-type events culminating around 2,300, 1,600, and 1,000 years ago and predating the "Little Ice Age" have been confirmed. The construction of a dating curve based on both Schmidt-hammer and cosmogenic (10Be) dating results shows high significance and demonstrates the high potential of this attempt.

    A workshop to obtain input from industry on the establishment of the Precision Joining Center (PJC) was held on July 10--12, 1991. The PJC is a center for training Joining Technologists in advanced joining techniques and concepts in order to promote the competitiveness of US industry. The center will be established as part of the DOE Defense Programs Technology Commercialization Initiative, and operated by EG G Rocky Flats in cooperation with the American Welding Society and the Colorado School of Mines Center for Welding and Joining Research. The overall objectives of the workshop were to validate the need for a Joining Technologists to fill the gap between the welding operator and the welding engineer, and to assure that the PJC will train individuals to satisfy that need. The consensus of the workshop participants was that the Joining Technologist is a necessary position in industry, and is currently used, with some variation, by many companies. It was agreed that the PJC core curriculum, as presented, would produce a Joining Technologist of value to industries that use precision joining techniques. The advantage of the PJC would be to train the Joining Technologist much more quickly and more completely. The proposed emphasis of the PJC curriculum on equipment intensive and hands-on training was judged to be essential.

    Introduction: A Canadian sports chiropractic research agenda has yet to be defined. The Delphi method can be utilized to achieve this purpose; however, the sample of experts who participate can influence the results. To better inform sample selection for future research agenda development, we set out to determine if differences in opinions about research priorities exist between chiropractors who have their sports specialty designation and those who do not. Methods: Fifteen sports clinical practice chiropractors who have their sports fellowship designation and fifteen without, were interviewed with a set of standardized questions about sports chiropractic research priorities. A centering resonance analysis and cluster analysis were conducted on the interview responses. Results: The two practitioner groups differed in their opinions about the type of research that they would like to see conducted, the research that would impact their clinical practice the most, and where they believed research was lacking. However, both groups were similar in their opinions about research collaborations. Conclusion: Sports clinical practice chiropractors, with their sports specialty designation and those without, differed in their opinions about sports chiropractic research priorities; however, they had similar opinions about research collaborations. These results suggest that it may be important to sample from both practitioner groups in future studies aimed at developing research agendas for chiropractic research in sport. PMID:28065995

    In the design of educational programs, much attention has been paid to teaching methods, needs assessment, an important part of the development of educational programs, generally is neglected. Another important aspect in educational program design is assessing effectiveness. The aims of this study were to design a formal needs assessment program to define the core contents of a faculty development program, and to determine whether participation in the faculty development program reinforced new teaching skills. A teacher-training program was designed at Shiraz University of Medical Sciences to help medical instructors boost their teaching skills. Needs assessment was done with nominal group technique followed by a 5-point Likert scale questionnaire. The program, imparted in workshop format, covered effective teaching methods, feedback, assessing knowledge and time management. Instruction was in the form of lectures, group discussions, case simulations, video presentations and role-plays. The program was evaluated in several phases using data triangulation and multi-item assessments of overall program quality in three major dimensions: Kirkpatrick program evaluation model, evaluation of the educational environment and qualitative analysis with open-ended questions. All participants in the study belonged to the academic staff of Shiraz University of Medical Sciences (n=396). Seven main categories were derived from nominal group techniques and questionnaires. After the program, participants rated the quality of the program highly. They felt that the educational intervention was appropriate and had a positive impact on their knowledge of effective teaching methods, feedback, knowledge assessment and time management. Assessment of the effectiveness of the program showed that participants reported significant improvements in their teaching abilities.

    Over the five-year period (2002-2006) the Oklahoma State University Industrial Assessment Center (IAC) performed energy assessments for 106 different clients, writing 835 recommendations, for a total of $23,937,099 in potential estimated annual savings. IAC clients served consisted of small and medium-sized manufacturers ranging from food manufactures to foundries. The OSU IAC served clients in Oklahoma, Kansas, Missouri, Arkansas, and Texas. In addition to client service, student training and instruction was a major accomplishment. The OSU IAC employed (and trained) 12 baccalaureate-level students, 17 masters-level graduate students, and 7 doctoral-level graduate students. Most are practicing in the energy management area. Training was focused on both energy assessment and safety. Safety training was both center-based training as well as on-site training. Energy management related training was focused on classroom (for academic credit) work at both the undergraduate and graduate level. IEM 4923 (Energy and Water Management) was developed to serve both the IAC as well as non-IAC students. It was delivered once per year, with enrollments of typically 10 to 20 students. This course was required for IAC student employees, both undergraduate and graduate. This course was patterned after the AEE CEM (five-day) course for practicing professionals. IEM 4923 required each student to attend at least one on-site assessment and write at least one recommendation for their client’s report. Hence, a hands-on approach was practiced. Advance level courses were used to train graduate students. Two courses played major roles here: IEM 5923 (Advanced Energy and Water Management) and IEM 5943 (Hazardous Material and Waste). Graduate student participation in these courses helped the IAC to gain additional perspectives in on-site assessment and resulting recommendations. Numerous hands-on demonstration/training was conducted by directors and graduate students in order to gain

    Future space missions will be significantly longer than current shuttle missions and new systems will be more complex than current systems. Increasing communication delays between crews and Earth-based support means that astronauts need to be prepared to handle the unexpected on their own. As crews become more autonomous, their potential span of control and required expertise must grow to match their autonomy. It is not possible to train for every eventuality ahead of time on the ground, or to maintain trained skills across long intervals of disuse. To adequately prepare NASA personnel for these challenges, new training approaches, methodologies, and tools are required. This research project aims at developing these training capabilities. By researching established training principles, examining future needs, and by using current practices in space flight training as test beds, both in Flight Controller and Crew Medical domains, this research project is mitigating program risks and generating templates and requirements to meet future training needs. Training efforts in Fiscal Year 09 (FY09) strongly focused on crew medical training, but also began exploring how Space Flight Resource Management training for Mission Operations Directorate (MOD) Flight Controllers could be integrated with systems training for optimal Mission Control Center (MCC) operations. The Training Task addresses Program risks that lie at the intersection of the following three risks identified by the Project: 1) Risk associated with poor task design; 2) Risk of error due to inadequate information; and 3) Risk associated with reduced safety and efficiency due to poor human factors design.

    Exposure ages and relative-age data are presented from eight sites in the Lomnica and Lomniczka valleys to provide essential information for reconstructing local glaciation chronology. A combination of {sup 10}Be exposure ages and Schmidt hammer data obtained for moraines indicate relatively short period of glacier accumulation lasting from 17.0{+-}0.4 ka to 13.6{+-}0.9 ka. Exposure age of 8.4{+-}0.3 ka measured on the lowermost section of the Lomnica cirque headwall further confirms the view of glacier preservation in favourable sites until the beginning of the Holocene. A comparison of the obtained chronological data with timing of mountain glaciation in the nearby Upa Valley is used to propose the first correlative model of Late Quaternary glaciation in the eastern part of the Krkonose Mountains. The correlation implies that the lowermost preserved moraines originated during the local maximum of the last glaciation whereas recessional moraines were deposited until the Lateglacial period. A subsequent melting of glaciers terminated at the beginning of the Holocene. The implications of the model are discussed and further investigations are suggested to extend its validity to the whole mountain area. (orig.)

    The Mission Operations Lab initiated a project to design, develop, deliver, test, and validate a unique training system for astronaut and ground support personnel. In an effort to keep training costs low, virtual training units (VTUs) have been designed based on images of actual hardware and manipulated by a touch screen style interface for ground support personnel training. This project helped modernized the training system and materials by integrating them with mobile devices for training when operators or crew are unavailable to physically train in the facility. This project also tested the concept of a handheld remote device to control integrated trainers using International Space Station (ISS) training simulators as a platform. The portable VTU can interface with the full-sized VTU, allowing a trainer co-located with a trainee to remotely manipulate a VTU and evaluate a trainee's response. This project helped determine if it is useful, cost effective, and beneficial for the instructor to have a portable handheld device to control the behavior of the models during training. This project has advanced NASA Marshall Space Flight Center's (MSFC's) VTU capabilities with modern and relevant technology to support space flight training needs of today and tomorrow.

    Nutritional status is a sensitive indicator of community health and nutrition. There is a growing realization that adequate nutrition is a necessary first step in the improvement of quality of life. Malnutrition and infection are connected by a vicious cycle. It is one of the greatest international health problems and the biggest challenges being faced today. Thus, to know the magnitude of undernutrition among preschool children and to find out the sensitive tool for detection of undernutrition, this study was conducted among children under - 5 years of age. To assess the validity of the nutritional indices for screening malnutrition. The study was a community-based, cross-sectional survey carried out in the catchment area of Rural Health Training Center, Rohilkhand Medical College, Bareilly. Various anthropometric criteria like, Kanawati, McLaren, Rao, Dugdale and weight for age according to the Indian Academy of Pediatrics (IAP) (modified Gomez) classification were used to define nutritional status. Data were entered and analyzed in SPSS and receiver operating characteristic (ROC) curves (sensitivity vs. 1 - specificity) were calculated for all the above mentioned indices. Age dependent criteria such as IAP (48.2% malnourished) and McLaren (48.3% malnourished) were followed by the age independent criteria such as Kanawati (74.3% malnourished), Dugdale (45.5% malnourished), and Rao (33.1% malnourished) to classify the mild to moderate malnutrition. ROC showed Dugdale as the best index for the judgement of malnutrition showing maximum area under the curve. Malnutrition being a public health problem leads to morbidity which is a vicious cycle and needs proper attention to curb its detrimental effect on the children.

    Federal public health advisors provide guidance and assistance to health departments to improve public health program work. The Centers for Disease Control and Prevention (CDC) prepares them with specialized training in administering public health programs. This article describes the evolving training and is based on internal CDC documents and interviews. The first federal public health advisors worked in health departments to assist with controlling syphilis after World War II. Over time, more CDC prevention programs hired them. To meet emerging needs, 3 major changes occurred: the Public Health Prevention Service, a fellowship program, in 1999; the Public Health Associate Program in 2007; and integration of those programs. Key components of the updated training are competency-based training, field experience, supervision, recruitment and retention, and stakeholder support. The enduring strength of the training has been the experience in a public health agency developing practical skills for program implementation and management.

    After being selected to the astronaut office, crewmembers go through an initial two year training flow, astronaut candidacy, where they learn the basic skills necessary for spaceflight. While the bulk of astronaut candidate training currently centers on the multiple subjects required for ISS operations (EVA skills, Russian language, ISS systems, etc.), training also includes geoscience training designed to train crewmembers in Earth observations, teach astronauts about other planetary systems, and provide field training designed to investigate field operations and boost team skills. This training goes back to Apollo training and has evolved to support ISS operations and future exploration missions.

    2017-01-01

    For NASA's Resource Prospector (RP) Lunar Rover Mission, we are moving away from a control center concept, to a fully distributed operation utilizing control nodes, with decision support from anywhere via mobile devices. This operations concept will utilize distributed information systems, notifications, mobile data access, and optimized mobile data display for off-console decision support. We see this concept of operations as a step in the evolution of mission operations from a central control center concept to a mission operations anywhere concept. The RP example is part of a trend, in which mission expertise for design, development and operations is distributed across countries and across the globe. Future spacecraft operations will be most cost efficient and flexible by following this distributed expertise, enabling operations from anywhere. For the RP mission we arrived at the decision to utilize a fully distributed operations team, where everyone operates from their home institution, based on evaluating the following factors: the requirement for physical proximity for near-real time command and control decisions; the cost of distributed control nodes vs. a centralized control center; the impact on training and mission preparation of flying the team to a central location. Physical proximity for operational decisions is seldom required, though certain categories of decisions, such as launch abort, or close coordination for mission or safety-critical near-real-time command and control decisions may benefit from co-location. The cost of facilities and operational infrastructure has not been found to be a driving factor for location in our studies. Mission training and preparation benefit from having all operators train and operate from home institutions.

    Anthropogenic noise in aquatic environments is a worldwide concern due to its potential adverse effects on the environment and aquatic life. The Hongkong-Zhuhai-Macao Bridge is currently under construction in the Pearl River Estuary, a hot spot for the Indo-Pacific humpbacked dolphin (Sousa chinensis) in China. The OCTA-KONG, the world's largest vibration hammer, is being used during this construction project to drive or extract steel shell piles 22 m in diameter. This activity poses a substantial threat to marine mammals, and an environmental assessment is critically needed. The underwater acoustic properties of the OCTA-KONG were analyzed, and the potential impacts of the underwater acoustic energy on Sousa, including auditory masking and physiological impacts, were assessed. The fundamental frequency of the OCTA-KONG vibration ranged from 15 Hz to 16 Hz, and the noise increments were below 20 kHz, with a dominant frequency and energy below 10 kHz. The resulting sounds are most likely detectable by Sousa over distances of up to 3.5 km from the source. Although Sousa clicks do not appear to be adversely affected, Sousa whistles are susceptible to auditory masking, which may negatively impact this species' social life. Therefore, a safety zone with a radius of 500 m is proposed. Although the zero-to-peak source level (SL) of the OCTA-KONG was lower than the physiological damage level, the maximum root-mean-square SL exceeded the cetacean safety exposure level on several occasions. Moreover, the majority of the unweighted cumulative source sound exposure levels (SSELs) and the cetacean auditory weighted cumulative SSELs exceeded the acoustic threshold levels for the onset of temporary threshold shift, a type of potentially recoverable auditory damage resulting from prolonged sound exposure. These findings may aid in the identification and design of appropriate mitigation methods, such as the use of air bubble curtains, "soft start" and "power down" techniques.

    The Faculty Fellowship program was revived in the summer of 2015 at NASA Marshall Space Flight Center, following a period of diminished faculty research activity here since 2006 when budget cuts in the Headquarters' Education Office required realignment. Several senior Marshall managers recognized the need to involve the Nation's academic research talent in NASA's missions and projects to the benefit of both entities. These managers invested their funds required to establish the renewed Faculty Fellowship program in 2015, a 10-week residential research involvement of 16 faculty in the laboratories and offices at Marshall. These faculty engineers and scientists worked with NASA collaborators on NASA projects, bringing new perspectives and solutions to bear. This Technical Memorandum is a compilation of the research reports of the 2015 Marshall Faculty Fellowship program, along with the Program Announcement (appendix A) and the Program Description (appendix B). The research touched on seven areas-propulsion, materials, instrumentation, fluid dynamics, human factors, control systems, and astrophysics. The propulsion studies included green propellants, gas bubble dynamics, and simulations of fluid and thermal transients. The materials investigations involved sandwich structures in composites, plug and friction stir welding, and additive manufacturing, including both strength characterization and thermosets curing in space. The instrumentation projects involved spectral interfero- metry, emissivity, and strain sensing in structures. The fluid dynamics project studied the water hammer effect. The human factors project investigated the requirements for close proximity operations in confined spaces. Another team proposed a controls system for small launch vehicles, while in astrophysics, one faculty researcher estimated the practicality of weather modification by blocking the Sun's insolation, and another found evidence in satellite data of the detection of a warm

  15. Combination of in situ cosmogenic nuclide (10Be) and Schmidt-hammer dating for the investigation of Late-Holocene lateral moraines in the Southern Alps of New Zealand

    Winkler, S.

    2009-04-01

    The investigation of Holocene glacier chronologies in high mountain regions is important for use of glaciers as indicators for climate change. Only detailed Holocene glacier chronologies offer the opportunity to improve our knowledge on the relationship between glaciers and climate factors, and to verify models of the future glacier development. The Southern Alps of New Zealand represent the southern hemispheric study area within the complex comparative current research project "MaMoGla" (Holocene and recent dynamics of maritime mountain glaciers). Among other goals, new methodological attempts to date the dominating lateral moraines in the Southern Alps in order to revise existing glaciers chronologies have been integrated in this project. The need for improvement of the existing Holocene glacier chronology of the Southern Alps/New Zealand is mainly caused by methodological uncertainties and the focus on Tasman Glaciers as unreliable key locality. Previously, radiocarbon (14C) dating of organic material (plant remains, organic-rich soil layers etc.) buried beneath or within the complex lateral moraines was the predominating ‘absolute' dating technique applied. In addition to older studies using the measurement of weathering rind thickness on boulders, the potential of the Schmidt-hammer as relative-age dating technique has clearly been demonstrated by the successful application on several lateral and latero-frontal moraine sequences in the Mt Cook/Aoraki National Park. The relatively homogenous and weathering/erosion-resistant bedrock yielded comparatively small standard errors and, thus, a relatively high time resolution of up to 200 - 300 years. Supported by statistical treatment of the raw field data, the Schmidt-hammer provided sufficient information to group the individual moraine ridges into moraine sequences and relate them to separate Little Ice Age-type events. However, the final ‘absolute' age dating of the moraine sequences remained open. As an

  6. Training by simulation

    Energy Technology Data Exchange (ETDEWEB)

    Angelini, E.

    1984-12-01

    Effective training by simulation is a matter of 1. accurate definition of the training need, 2. selecting the right hardware/software package to do the job cost effectively, 3. careful, methodical building of the training program and 4. an appropriate setting, such as a well-equipped training center. Several points seem clear: 1. ''Computer shock'' or computer phobia -- that is, fear of the simulator, can be a factor with some of the older operators. But it quickly disappears once they're into the program, and learn the versatility and the exciting dynamics of simulators. 2. Operator training is becoming more sophisticated throughout the HPI. Among other things, operators should get out into the plant to learn more about how their actions in the control room impact the plant. Operators are becoming more ''big picture'' oriented. 3. When inexperienced training instructors are used, they should attend a good ''train the trainer'' course emphasizing platform skills and instructional technology. 4. Operators need as much ''hands on'' experience with the plant's actual operating equipment as possible. The cognitive ''linkage'' between that equipment and what they see on the CRT is vitally important.

  9. [Laparoscopic hysterectomy and training].

    Science.gov (United States)

    Tomov, S; Gorchev, G

    2012-01-01

    Mastering and perception of laparoscopic hysterectomy by gynecologists is a slow process because of the learners' insufficient experience and inadequate training, lack of hospital equipment and the low levels of reimbursement. Analysing science literature data and their own 7-year experience (2004-2011), the authors suggest a training program for laparoscopic gynecological surgery. The process of education for laparoscopic hysterectomy implementation has to be performed at highly specialized centers by highly qualified specialists in accordance with strict principles and strict sequence. After mastering all the laparoscopic approaches to hysterectomy, laparoscopic hysterectomy has to be a method of choice among the methods used by the contemporary gynecologic surgeon.

    In the past, paper Training Attestations were printed during the first quarter of a New Year for Staff Members having followed courses and seminars the previous year in the context of CERN's official Training Programmes.  The attestations were sent to Divisional Training Officers (DTO's) for distribution to all Staff Members concerned within their Division. In practise many Staff Members did not find this paper useful, however some expressed a wish to be able to have access to a self-service facility in case of need. This change was discussed by the Joint Training Board (JTB) and with the DTO's during 2003 and was supported. As a consequence, following a collaboration between HR-PMD and IT-AIS, from 2004 onwards paper Training Attestations will no longer be printed and distributed as before.

    Bryne, Vicky; Connell, Erin; Barshi, Immanuel; Arsintescu, L.

    2009-01-01

    Accidents and incidents show that high workload-induced stress and poor teamwork skills lead to performance decrements and errors. Research on teamwork shows that effective teams are able to adapt to stressful situations, and to reduce workload by using successful strategies for communication and decision making, and through dynamic redistribution of tasks among team members. Furthermore, superior teams are able to recognize signs and symptoms of workload-induced stress early, and to adapt their coordination and communication strategies to the high workload, or stress conditions. Mission Control Center (MCC) teams often face demanding situations in which they must operate as an effective team to solve problems with crew and vehicle during onorbit operations. To be successful as a team, flight controllers (FCers) must learn effective teamwork strategies. Such strategies are the focus of Space Flight Resource Management (SFRM) training. SFRM training in MOD has been structured to include some classroom presentations of basic concepts and case studies, with the assumption that skill development happens in mission simulation. Integrated mission simulations do provide excellent opportunities for FCers to practice teamwork, but also require extensive technical knowledge of vehicle systems, mission operations, and crew actions. Such technical knowledge requires lengthy training. When SFRM training is relegated to integrated simulations, FCers can only practice SFRM after they have already mastered the technical knowledge necessary for these simulations. Given the centrality of teamwork to the success of MCC, holding SFRM training till late in the flow is inefficient. But to be able to train SFRM earlier in the flow, the training cannot rely on extensive mission-specific technical knowledge. Hence, the need for a generic SFRM training framework that would allow FCers to develop basic teamwork skills which are mission relevant, but without the required mission knowledge

    In this photograph, Apollo 11 astronaut Neil A. Armstrong uses a geologist's hammer in selecting rock specimens during a geological field trip to the Quitman Mountains area near the Fort Quitman ruins in far west Texas. Armstrong, alongside astronaut Edwin (Buzz) Aldrin, practiced gathering rock specimens using special lunar geological tools in preparation for the first Lunar landing. Mission was accomplished in July of the same year. Aboard the Marshall Space Fight center (MSFC) developed Saturn V launch vehicle, the Apollo 11 mission launched from The Kennedy Space Center, Florida on July 16, 1969 and safely returned to Earth on July 24, 1969. The 3-man crew aboard the flight consisted of Armstrong, commander; Aldrin, Lunar Module pilot; and a third astronaut Michael Collins, Command Module pilot. Armstrong was the first human to ever stand on the lunar surface, followed by Aldrin, while Collins remained in lunar orbit. The crew collected 47 pounds of lunar surface material which was returned to Earth for analysis. The lunar surface exploration was concluded in 2½ hours.
