We analysed the patterns of coordination of striking movement and perceptuomotor control of stone hammers in wild bearded capuchin monkeys, Sapajus libidinosus as they cracked open palm nut using hammers of different mass, a habitual behaviour in our study population. We aimed to determine why these monkeys cannot produce conchoidally fractured flakes as do contemporary human knappers or as did prehistoric hominin knappers. We found that the monkeys altered their patterns of coordination of movement to accommodate changes in hammer mass. By altering their patterns of coordination, the monkeys kept the strike's amplitude and the hammer's velocity at impact constant with respect to hammer mass. In doing so, the hammer's kinetic energy at impact-which determines the propagation of a fracture/crack in a nut-varied across hammers of different mass. The monkeys did not control the hammer's kinetic energy at impact, the key parameter a perceiver-actor should control while knapping stones. These findings support the hypothesis that the perceptuomotor control of stone hammers in wild bearded capuchin monkeys is inadequate to produce conchoidally fractured flakes by knapping stones, as do humans. © 2018 The Author(s).

Influences on water-hammer wave shape: an experimental study

NASA Astrophysics Data System (ADS)

Traudt, T.; Bombardieri, C.; Manfletti, C.

2016-09-01

Water-hammer phenomena are of strong interest in a number of different industrial fields, amongst which the space industry. Here the priming of feedlines during start-up of an engine as well as the rapid closing of valves upon shutdown may lead to pressure peaks symptomatic of a water-hammer wave. Test benches used to conduct tests on future as well as current engines are also sensitive to water-hammer waves traveling along their feedlines. To enhance the understanding of water-hammer, we investigated different configurations and their influence on the wave shape in the frequency domain. The configurations feature a coiled pipe setup with a support structure and without a support structure. Two other phenomena will be presented. We found a beat phenomenon which is likely to be the so called Poisson-coupling beat. Finally we will show that the second water-hammer peak can reach pressures a lot higher than the first peak by additive interference of the primary and secondary water-hammer wave.

Development of a Piezoelectric Rotary Hammer Drill

NASA Technical Reports Server (NTRS)

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.

2008-06-30

This study aimed to compare British, British Pakistani and Native Pakistani (from Pakistan) medical students' beliefs about the manifestation, causes and cures of schizophrenia, prior to any psychiatric training. A total of 305 participants completed a questionnaire on general beliefs about people with schizophrenia, causal explanations concerning the aetiology of schizophrenia and the role of hospitals and society in treating people with schizophrenia. It was predicted that compared with the British and British Pakistanis, the Pakistanis would have more negative beliefs and attitudes, considering people with schizophrenia to be more dangerous and unpredictable; they were also expected to use more superstitious beliefs to explain the cause of schizophrenia and its symptoms; as well as believe more in seeking help from God and faith healers. There was strong evidence to suggest that Pakistanis possessed more negative beliefs and attitudes about people with schizophrenia, but there was no evidence to indicate that Pakistanis believed more in superstitious causal explanations. Pakistanis were more likely to consider seeking help from faith healers, but not God, compared with British Pakistanis and the British. Results confirm previous European-Asian difference in the understanding of the cause, manifestation and cure of schizophrenia. The impact of traditional and Western cultural influences on British Pakistanis is considered.

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 7more » 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.« less

Treatise on water hammer in hydropower standards and guidelines

Bergant, A.; Karney, B.; Pejović, S.; Mazij, J.

2014-03-01

This paper reviews critical water hammer parameters as they are presented in official hydropower standards and guidelines. A particular emphasize is given to a number of IEC standards and guidelines that are used worldwide. The paper critically assesses water hammer control strategies including operational scenarios (closing and opening laws), surge control devices (surge tank, pressure regulating valve, flywheel, etc.), redesign of the water conveyance system components (tunnel, penstock), or limitation of operating conditions (limited operating range) that are variably covered in standards and guidelines. Little information is given on industrial water hammer models and solutions elsewhere. These are briefly introduced and discussed in the light of capability (simple versus complex systems), availability of expertise (in house and/or commercial) and uncertainty. The paper concludes with an interesting water hammer case study referencing the rules and recommendations from existing hydropower standards and guidelines in a view of effective water hammer control. Recommendations are given for further work on development of a special guideline on water hammer (hydraulic transients) in hydropower plants.

Infrasound Generation from the HH Seismic Hammer.

Jones, Kyle Richard

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.

Effect of hammer mass on upper extremity joint moments.

PubMed

Balendra, Nilanthy; Langenderfer, Joseph E

2017-04-01

This study used an OpenSim inverse-dynamics musculoskeletal model scaled to subject-specific anthropometrics to calculate three-dimensional intersegmental moments at the shoulder, elbow and wrist while 10 subjects used 1 and 2 lb hammers to drive nails. Motion data were collected via an optoelectronic system and the interaction of the hammer with nails was recorded with a force plate. The larger hammer caused substantial increases (50-150%) in moments, although increases differed by joint, anatomical component, and significance of the effect. Moment increases were greater in cocking and strike/follow-through phases as opposed to swinging and may indicate greater potential for injury. Compared to shoulder, absolute increases in peak moments were smaller for elbow and wrist, but there was a trend toward larger relative increases for distal joints. Shoulder rotation, elbow varus-valgus and pronation-supination, and wrist radial-ulnar deviation and rotation demonstrated large relative moment increases. Trial and phase durations were greater for the larger hammer. Changes in moments and timing indicate greater loads on musculoskeletal tissues for an extended period with the larger hammer. Additionally, greater variability in timing with the larger hammer, particularly for cocking phase, suggests differences in control of the motion. Increased relative moments for distal joints may be particularly important for understanding disorders of the elbow and wrist associated with hammer use. Copyright © 2016 Elsevier Ltd.

WATER HAMMER OSCILLATIONS IN THE IRRIGATION FACILITIES

NASA Astrophysics Data System (ADS)

Kurata, Kouichi; Sasaki, Katsuhito; Makihata, Toshiaki

In case a gate installed at the end of discharge conduit is vibrating during discharge, or an air valve is vibrating during water-filling operation into the conduit pipe between main gate and auxiliary gate, and vibration period tv is larger than tc (water hammer propagation time) that is equivalent to the phenomenon of slow closure, there is a possibility that water hammer oscillation in the discharge conduit could be induced. In this paper, by using two case examples, vibration phenomena transmitted to each part are analyzed, on the basis of water pressure fluctuation and pressure wave propagation due to occurrence of water hammer oscillation.

Pump-stopping water hammer simulation based on RELAP5

Yi, W. S.; Jiang, J.; Li, D. D.; Lan, G.; Zhao, Z.

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.

Vibration and recoil control of pneumatic hammers. [by air flow pressure regulation

Vibration sources are described for pneumatic hammers used in the mining industry (pick hammers), in boiler shops (riveting hammers), etc., bringing to light the fact that the principal vibration source is the variation in air pressure inside the cylinder. The present state of the art of vibration control of pneumatic hammers as it is practiced abroad, and the solutions adopted for this purpose, are discussed. A new type of pneumatic hammer with a low noise and vibration level is presented.

Voice Coil Percussive Mechanism Concept for Hammer Drill

NASA Technical Reports Server (NTRS)

Okon, Avi

2009-01-01

A hammer drill design of a voice coil linear actuator, spring, linear bearings, and a hammer head was proposed. The voice coil actuator moves the hammer head to produce impact to the end of the drill bit. The spring is used to store energy on the retraction and to capture the rebound energy after each impact for use in the next impact. The maximum actuator stroke is 20 mm with the hammer mass being 200 grams. This unit can create impact energy of 0.4 J with 0.8 J being the maximum. This mechanism is less complex than previous devices meant for the same task, so it has less mass and less volume. Its impact rate and energy are easily tunable without changing major hardware components. The drill can be driven by two half-bridges. Heat is removed from the voice coil via CO2 conduction.

Reconstruction of piano hammer force from string velocity.

PubMed

Chaigne, Antoine

2016-11-01

A method is presented for reconstructing piano hammer forces through appropriate filtering of the measured string velocity. The filter design is based on the analysis of the pulses generated by the hammer blow and propagating along the string. In the five lowest octaves, the hammer force is reconstructed by considering two waves only: the incoming wave from the hammer and its first reflection at the front end. For the higher notes, four- or eight-wave schemes must be considered. The theory is validated on simulated string velocities by comparing imposed and reconstructed forces. The simulations are based on a nonlinear damped stiff string model previously developed by Chabassier, Chaigne, and Joly [J. Acoust. Soc. Am. 134(1), 648-665 (2013)]. The influence of absorption, dispersion, and amplitude of the string waves on the quality of the reconstruction is discussed. Finally, the method is applied to real piano strings. The measured string velocity is compared to the simulated velocity excited by the reconstructed force, showing a high degree of accuracy. A number of simulations are compared to simulated strings excited by a force derived from measurements of mass and acceleration of the hammer head. One application to an historic piano is also presented.

Screening reactor steam/water piping systems for water hammer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Griffith, P.

1997-09-01

A steam/water system possessing a certain combination of thermal, hydraulic and operational states, can, in certain geometries, lead to a steam bubble collapse induced water hammer. These states, operations, and geometries are identified. A procedure that can be used for identifying whether an unbuilt reactor system is prone to water hammer is proposed. For the most common water hammer, steam bubble collapse induced water hammer, six conditions must be met in order for one to occur. These are: (1) the pipe must be almost horizontal; (2) the subcooling must be greater than 20 C; (3) the L/D must be greatermore » than 24; (4) the velocity must be low enough so that the pipe does not run full, i.e., the Froude number must be less than one; (5) there should be void nearby; (6) the pressure must be high enough so that significant damage occurs, that is the pressure should be above 10 atmospheres. Recommendations on how to avoid this kind of water hammer in both the design and the operation of the reactor system are made.« less

2014-01-01

In 2002, the British Columbia Ministry of Health and the British Columbia Medical Association (now Doctors of BC) came together to form the British Columbia General Practice Services Committee to bring about transformative change in primary care in British Columbia, Canada. This committee's approach to primary care was to respond to an operational problem--the decline of family practice in British Columbia--with an operational solution--assist general practitioners to provide better care by introducing new incentive fees into the fee-for-service payment schedule, and by providing additional training to general practitioners. This may be referred to as a "soft power" approach, which can be summarized in the abbreviation RISQ: focus on Relationships; provide Incentives for general practitioners to spend more time with their patients and provide guidelines-based care; Support general practitioners by developing learning modules to improve their practices; and, through the incentive payments and learning modules, provide better Quality care to patients and improved satisfaction to physicians. There are many similarities between the British Columbian approach to primary care and the US patient-centered medical home.

When does tool use become distinctively human?: Hammering in young children

PubMed Central

Kahrs, Björn; Lockman, Jeffrey J.; Jung, Wendy

2013-01-01

This study examines the development of hammering within an ontogenetic and evolutionary framework using motion-capture technology. Twenty-four right-handed toddlers (19–35 months) wore reflective markers while hammering a peg into a peg-board. The study focuses on the motor characteristics that make tool use uniquely human: wrist involvement, lateralization, and handle use. Older children showed more distally controlled movements, characterized by relatively more reliance on the wrist, but only when hammering with their right hand. Greater age, use of the right hand, and more wrist involvement were associated with higher accuracy; handle use did not systematically change with age. Collectively, the results provide new insights about the emergence of hammering in young children and when hammering begins to manifest distinctively human characteristics. PMID:24128178

Do chimpanzees use weight to select hammer tools?

PubMed

Schrauf, Cornelia; Call, Josep; Fuwa, Koki; Hirata, Satoshi

2012-01-01

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.

This article examines three films by legendary experimental filmmaker Barbara Hammer that deal with the sick, aging, or dying body: Optic Nerve (1985), Sanctus (1990), and A Horse is Not a Metaphor (2008). By analyzing films that do not explicitly confront sexual identity, this article questions the continuing usefulness of the designation "lesbian filmmaker" when considering Hammer's diverse body of work. Tracing the "double consciousness" through which Hammer approaches the body and its construction in patriarchy-particularly in the discourse of medicine-this article argues that Hammer's is a thoroughly corporeal, but not exclusively lesbian, cinema.

CFD Analysis of the Anti-Surge Effects by Water Hammering

NASA Astrophysics Data System (ADS)

Kim, Tae-oh; Jeong, Hyo-min; Chung, Han-shik; Lee, Sin-il; Lee, Kwang-sung

Water hammering occurs due to the surge effect that comes from operating the pump, sudden stop during the operating due to a blackout and rapid open and close of the valve. By the water hammering of the pipeline and the pump, the valve are damaged. In this paper, transient analysis is conducted by CFD (Computational Fluid Dynamics). The purpose of this paper is to provide the research data about the change of the pressure and flow in the pipe that caused by the water hammering.

Proximal forearm extensor muscle strain is reduced when driving nails using a shock-controlled hammer.

2016-10-01

Repetitive hammer use has been associated with strain and musculoskeletal injuries. This study investigated if using a shock-control hammer reduces forearm muscle strain by observing adverse physiological responses (i.e. inflammation and localized edema) after use. Three matched framing hammers were studied, including a wood-handle, steel-handle, and shock-control hammer. Fifty volunteers were randomly assigned to use one of these hammers at a fatiguing pace of one strike every second, to seat 20 nails in a wood beam. Magnetic resonance imaging was used to scan the forearm muscles for inflammation before the task, immediately after hammering, and one to two days after. Electromyogram signals were measured to estimate grip exertions and localized muscle fatigue. High-speed video was used to calculate the energy of nail strikes. While estimated grip force was similar across the three hammers, the shock-control hammer had 40% greater kinetic energy upon impact and markedly less proximal extensor muscle edema than the wood-handle and steel-handle hammers, immediately after use (p<.05). Less edema observed for the shock-control hammer suggests that isolating handle shock can mitigate strain in proximal forearm extensor muscles. Copyright © 2016 Elsevier Ltd. All rights reserved.

[Adam hammer (1818 - 1878) - remarks on a forgotten pioneer of ether anaesthesia in obstetrics].

Goerig, M; Streckfuss, W

2004-05-01

Adam Hammer, born in 1818, and working as a doctor for the poor since 1847 in Mannheim, was the first person in the German speaking world to use ether for pain relief during labor on February 18th 1847. He took part in the abortive April 1848 Revolution in Mannheim - a pinnacle of German liberalism and later of political radicalism, which attented to abolish the Monarchy and introduce a democratic Republic. After the revolution was put down, Hammer emigrated to the United States and settled down in St. Louis, Missouri. Remaining politically active, he joined the Republican Party, founded in 1854 and served as a military surgeon in the Union Army during the American Civil War. Even before the war, he was engaged in efforts to improve the level of medical training in America and was involved with the foundation of High Schools which offered training courses along the lines of German universities. His ideas and innovations were not introduced immediately, but had a significant impact on medical training methology later on in the US. During a visit in Europe in 1876, he was the first to diagnose a coronary thombosis as the cause of a heart attack on a live patient. The diagnosis was later confirmed by post-morten autopsy on the patient. In 1877 he returned to Germany and died one year later. The biography of Adam Hammer mirrows that of many other German-Americans whose emigration proved to be a gain for America but a loss for Germany. This story was destinated to be repeated in terrible circumstances some decades later.

Near-surface seismic surveys often employ hammer impacts to create seismic energy. Shear-wave surveys using horizontally polarized waves require horizontal hammer impacts against a rigid object (the source) that is coupled to the ground surface. I have designed, built, and tested a source made out of aluminum and equipped with spikes to improve coupling. The source is effective in a variety of settings, and it is relatively simple and inexpensive to build.

2011-12-01

Distributed analysis of LHC data is an I/O-intensive activity which places large demands on the internal network, storage, and local disks at remote computing facilities. Commissioning and maintaining a site to provide an efficient distributed analysis service is therefore a challenge which can be aided by tools to help evaluate a variety of infrastructure designs and configurations. HammerCloud is one such tool; it is a stress testing service which is used by central operations teams, regional coordinators, and local site admins to (a) submit arbitrary number of analysis jobs to a number of sites, (b) maintain at a steady-state a predefined number of jobs running at the sites under test, (c) produce web-based reports summarizing the efficiency and performance of the sites under test, and (d) present a web-interface for historical test results to both evaluate progress and compare sites. HammerCloud was built around the distributed analysis framework Ganga, exploiting its API for grid job management. HammerCloud has been employed by the ATLAS experiment for continuous testing of many sites worldwide, and also during large scale computing challenges such as STEP'09 and UAT'09, where the scale of the tests exceeded 10,000 concurrently running and 1,000,000 total jobs over multi-day periods. In addition, HammerCloud is being adopted by the CMS experiment; the plugin structure of HammerCloud allows the execution of CMS jobs using their official tool (CRAB).

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.

Effects of air vessel on water hammer in high-head pumping station

NASA Astrophysics Data System (ADS)

Wang, L.; Wang, F. J.; Zou, Z. C.; Li, X. N.; Zhang, J. C.

2013-12-01

Effects of air vessel on water hammer process in a pumping station with high-head were analyzed by using the characteristics method. The results show that the air vessel volume is the key parameter that determines the protective effect on water hammer pressure. The maximum pressure in the system declines with increasing air vessel volume. For a fixed volume of air vessel, the shape of air vessel and mounting style, such as horizontal or vertical mounting, have little effect on the water hammer. In order to obtain good protection effects, the position of air vessel should be close to the outlet of the pump. Generally, once the volume of air vessel is guaranteed, the water hammer of a entire pipeline is effectively controlled.

Ulnar hammer syndrome is an uncommon form of arterial insufficiency. Many treatments have been described, and debate continues about the best option. The goal of this systematic review was to determine whether ulnar hammer syndrome has an occupational association, to identify the most reliable diagnostic test, and to determine the best treatment modality. A comprehensive literature search was conducted using the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, and EMBASE. Data from articles meeting inclusion criteria were collected in duplicate. Methodological quality of studies was assessed using the Methodological Index for Nonrandomized Studies scale. Thirty studies were included in the systematic review. No randomized controlled trials were identified. There is low-quality evidence suggestive of an association between exposure to repetitive hand trauma and vibration and ulnar hammer syndrome. Various diagnostic investigations were used, but few were compared, making it difficult to determine the most reliable diagnostic test. Numerous nonoperative and operative treatments were reported. With nonoperative treatment, 12 percent had complete resolution and 70 percent had partial resolution of their symptoms. Of patients treated operatively, 42.5 percent had complete resolution and 42.5 percent had partial resolution of their symptoms. The heterogeneity in study design and outcome measures limits definitive conclusions about occupational association, best diagnostic test, and treatment for ulnar hammer syndrome. However, there is low-quality evidence that suggests that most patients with ulnar hammer syndrome will have partial relief of symptoms with nonoperative treatment, and operative treatment results in complete or partial resolution of symptoms in the majority of cases.

This paper reports results from a detailed study of the careers of laboratory technicians in British medical research. Technicians and their contributions are very frequently missing from accounts of modern medicine, and this project is an attempt to correct that absence. The present paper focuses almost entirely on the Medical Research Council's National Institute for Medical Research in North London, from the first proposal of such a body in 1913 until the mid 1960s. The principal sources of information have been technical staff themselves, largely as recorded in an extensive series of oral history interviews. These have covered a wide range of issues and provide valuable perspectives about technicians' backgrounds and working lives. PMID:18548906

The use of riveting hammers can expose workers to harmful levels of hand-transmitted vibration (HTV). As a part of efforts to reduce HTV exposures through tool selection, the primary objective of this study was to evaluate the applicability of a standardized laboratory-based riveting hammer assessment protocol for screening riveting hammers. The second objective was to characterize the vibration emissions of reduced vibration riveting hammers and to make approximations of the HTV exposures of workers operating these tools in actual work tasks. Eight pneumatic riveting hammers were selected for the study. They were first assessed in a laboratory using the standardized method for measuring vibration emissions at the tool handle. The tools were then further assessed under actual working conditions during three aircraft sheet metal riveting tasks. Although the average vibration magnitudes of the riveting hammers measured in the laboratory test were considerably different from those measured in the field study, the rank orders of the tools determined via these tests were fairly consistent, especially for the lower vibration tools. This study identified four tools that consistently exhibited lower frequency-weighted and unweighted accelerations in both the laboratory and workplace evaluations. These observations suggest that the standardized riveting hammer test is acceptable for identifying tools that could be expected to exhibit lower vibrations in workplace environments. However, the large differences between the accelerations measured in the laboratory and field suggest that the standardized laboratory-based tool assessment is not suitable for estimating workplace riveting hammer HTV exposures. Based on the frequency-weighted accelerations measured at the tool handles during the three work tasks, the sheet metal mechanics assigned to these tasks at the studied workplace are unlikely to exceed the daily vibration exposure action value (2.5 m s−2) using any of the

The influence of cementation technology of titanium alloy Ti-Al-Mn on its wear resistance is studied. It is established that after lubrication a friction pair with mineral oil the wear resistance of the cemented titanium alloy is comparable to wear resistance of the tempered steel 12HN3A, and in water medium surpasses it by 1.5 times. Decrease in the tendency to seizure with steel is the main reason for increase of wear resistance of titanium alloy. Industrial tests of the ASH43 hammer have shown that the use of titanium alloys for the manufacture of hammer strikers allows to increase impact capacity by 1.5 times and to increase drilling rate by 30 % compared to hammers with steel strikers.

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

NASA Astrophysics Data System (ADS)

Kuratani, F.; Yoshida, T.; Koide, T.; Mizuta, T.; Osamura, K.

2016-09-01

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.

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.

In this study, we compared the advantages and disadvantages of piezosurgery and hammer-chisel used in endoscopic dacryocystorhinostomy (EDCR). Between January 2012 and January 2016, 10 women and 8 men in whom piezosurgery was used (group 1) and 11 women and 7 men in whom hammer-chisel was used (group 2) during EDCR operations were compared retrospectively. Recurrence, operation time, postoperative bleeding, and operative cost were evaluated in patients who were followed for an average of 11.8 months. In addition, visual analogue scale (VAS) was used to assess pain at 6 hours postoperatively. No recurrence was observed in group 1, but recurrence was observed in 2 patients in group 2 (P = 0.685). There was no postoperative bleeding in both groups. The mean duration of operation was 30.6 ± 8.2 minutes in group 1 and 46.8 ± 9.5 minutes in group 2 (P = 0.038). The VAS score in group 1 was 2.7 ± 1.4 and the VAS score in group 2 was 5.8 ± 2.2 (P = 0.01). Piezosurgery costs an additional $325 for each patient while the use of the hammer-chisel does not incur additional costs. Piezosurgery causes shorter operation time, less recurrence, and less pain when compared with hammer-chisel.

The aim of this study was to identify factors that influence career choice in UK medical students. Students at seven institutions were invited to rate how important various factors were on influencing their career choices and how interested they were in pursuing different specialties. The influence of interpersonal relationship networks on career choice was also evaluated. 641 responses were collected. 44% (283) were male, 16% (105) were graduates and 41% (263) were final-year students. For Dermatology (p = 0.009), Paediatrics (p = 0.000), Radiology (p = 0.000), Emergency Medicine (p = 0.018) and Cardiothoracic Surgery (p = 0.000), there was a clear correlation between completing a clinical attachment and an interest in pursuing the specialty. Perceived characteristics of the speciality, individually and in clusters were considered important by specific subgroups of students, such as those interested in surgery. These students considered prestige (p = 0.0003), role models (p = 0.014), financial rewards after training (p = 0.0196) and technical challenge (p = 0.0011) as important factors. Demographics such as sex and age played a significant role in career choice. Interpersonal relationship networks do not have a significant influence on career intentions. This study shows that the career intentions of British medical students are influenced by their undergraduate experience and by the weight they place on different specialty-related factors.

Ultrasonic/Sonic Rotary-Hammer Drills

2010-01-01

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

Valve regulation is an effective method for process control during the water hammer. The principle of d'Alembert traveling wave theory was used in this paper to construct the exact analytical solution of the water hammer, and the optimal speed law of the valve that can reduce the water hammer pressure in the maximum extent was obtained. Combining this law with the valve characteristic curve, the principle corresponding to the valve opening changing with time was obtained, which can be used to guide the process of valve closing and to reduce the water hammer pressure in the maximum extent.

Automatic hammering of nano-patterns on special polymer film by using a vibrating AFM tip

PubMed Central

2012-01-01

Complicated nano-patterns with linewidth less than 18 nm can be automatically hammered by using atomic force microscopy (AFM) tip in tapping mode with high speed. In this study, the special sample was thin poly(styrene-ethylene/butylenes-styrene) (SEBS) block copolymer film with hexagonal spherical microstructures. An ordinary silicon tip was used as a nano-hammer, and the entire hammering process is controlled by a computer program. Experimental results demonstrate that such structure-tailored thin films enable AFM tip hammering to be performed on their surfaces. Both imprinted and embossed nano-patterns can be generated by using a vibrating tip with a larger tapping load and by using a predefined program to control the route of tip movement as it passes over the sample’s surface. Specific details for the fabrication of structure-tailored SEBS film and the theory for auto-hammering patterns were presented in detail. PMID:22889045

From medical astrology to medical astronomy: sol-lunar and planetary theories of disease in British medicine, c. 1700-1850.

After 1700, astrology lost the respect it once commanded in medical circles. But the belief that the heavens influenced bodily health persisted - even in learned medicine - until well into the nineteenth century. The continuing vitality of these ideas owed much to the new empirical and mechanical outlook of their proponents. Taking their cue from the work of Robert Boyle and Richard Mead, a number of British practitioners amassed statistical evidence which purported to prove the influence of the Moon upon fevers and other diseases. Such ideas flourished in the colonies and in the medical services of the armed forces, but their exponents were not marginal men. Some, like James Lind, were widely respected and drew support for their views from such influential figures as Erasmus Darwin.

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.

Objective To determine the association between systemic medication use and intraocular pressure (IOP) in a population of older British men and women. Design Population-based, cross-sectional study. Participants We included 7093 participants from the European Prospective Investigation into Cancer–Norfolk Eye Study. Exclusion criteria were a history of glaucoma therapy (medical, laser, or surgical), IOP asymmetry between eyes of >5 mmHg, and missing data for any covariables. The mean age of participants was 68 years (range, 48–92) and 56% were women. Methods We measured IOP using the Ocular Response Analyzer. Three readings were taken per eye and the best signal value of the Goldmann-correlated IOP value considered. Participants were asked to bring all their medications and related documentation to the health examination, and these were recorded by the research nurse using an electronic case record form. The medication classes examined were angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, α-blockers, β-blockers, calcium channel blockers, diuretics, nitrates, statins, insulin, biguanides, sulfonylureas, aspirin, and other nonsteroidal anti-inflammatory drugs. We examined associations between medication use and IOP using multivariable linear regression models adjusted for age, sex, and body mass index. Models containing diabetic medication were further adjusted for glycosylated hemoglobin levels. Main Outcome Measures Mean IOP of the right and left eyes. Results Use of systemic β-blockers (−0.92 mmHg; 95% CI, −1.19, −0.65; P<0.001) and nitrates (−0.63 mmHg; 95% CI, −1.12, −0.14; P = 0.011) were independently associated with lower IOP. The observed associations between statin or aspirin use with IOP were no longer significant after adjustment for β-blocker use. Conclusions This is the first population-based study to demonstrate and quantify clinically significant differences in IOP among participants using systemic �

This study examined cultural differences in beliefs about health and illness to explore differences in younger and older British Caucasians' and British Gujarati Indian immigrants' beliefs about health and illness. This study required a matched group consisting of first- and second-generation Gujarati Indian immigrants and native British Caucasians to complete a questionnaire assessing their beliefs concerning health and illness. Factor analysis of the health beliefs questionnaire identified six clear factors accounting for 36.04% of the variance. Subsequent ANCOVAs conducted on the factor scores, partialling out the demographic differences between the participants, revealed that Gujarati Indian immigrants agreed with items reflecting supernatural explanations of ill health more than indigenous British Caucasian participants. Older Indian immigrants also rated chance-related factors as more important than older Caucasian immigrants. There were no significant differences between the Gujarati Indian immigrants and British Caucasians in terms of attributions made to psychological factors and self-responsibility, social factors and life circumstances, medical treatment and physical vulnerability and the external environment. Findings are discussed in relation to the model proposed by Helman (2001) and the impact of migration on health beliefs systems; practical implications of the findings are also highlighted.

Although medical students have increasingly more opportunities to participate in international electives, their experiences are usually unstructured and the literature referring to their learning outcomes, educational environment, and assessment is scanty. This study was undertaken to clarify qualitatively what students learn from their international electives. We carried out semi-structured individual interviews with 15 Japanese students studying clinical medicine in British medical schools and six British students studying in Japanese medical schools. The thematic synthesis method was used in analysing the transcribed data and triangulation by multiple researchers was used to achieve higher reliability. The main learning outcomes identified were skills in history taking and physical examination with clinical reasoning and in management of diseases rarely seen in the students' own countries; awareness of clinical ethics and merits and demerits of different systems of healthcare and medical education; sensitivity to issues in doctor-patient relationships and work ethics; enhancement of cultural competence; and personal development. Most learning outcomes of international electives are culture- or system-dependent. Students achieved outcomes related closely to medical professionalism, mainly through reflection. International electives may give students opportunities to learn both professionalism and cultural competence.

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

The development of cable force during hammer-throw turns is crucial to the throw distance. In this paper, we present a method that is capable of measuring cable force in real time and, as it does not interfere with technique, it is capable of providing immediate feedback to coaches and athletes during training. A strain gauge was mounted on the wires of three hammers to measure the tension in the wire and an elite male hammer thrower executed three throws with each hammer. The output from the gauges was recorded by a data logger positioned on the lower back of the thrower. The throws were captured by three high-speed video cameras and the three-dimensional position of the hammer's head was determined by digitizing the images manually. The five best throws were analysed. The force acting on the hammer's head was calculated from Newton's second law of motion and this was compared with the force measured via the strain gauge. Qualitatively the time dependence of the two forces was essentially the same, although the measured force showed more detail in the troughs of the force-time curves. Quantitatively the average difference between the measured and calculated forces over the five throws was 76 N, which corresponds to a difference of 3.8% for a cable force of 2000 N.

Identification of characteristic frequencies of damaged railway tracks using field hammer test measurements

Oregui, M.; Li, Z.; Dollevoet, R.

2015-03-01

In this paper, the feasibility of the Frequency Response Function (FRF)-based statistical method to identify the characteristic frequencies of railway track defects is studied. The method compares a damaged track state to a healthy state based on non-destructive field hammer test measurements. First, a study is carried out to investigate the repeatability of hammer tests in railway tracks. By changing the excitation and measurement locations it is shown that the variability introduced by the test process is negligible. Second, following the concepts of control charts employed in process monitoring, a method to define an approximate healthy state is introduced by using hammer test measurements at locations without visual damage. Then, the feasibility study includes an investigation into squats (i.e. a major type of rail surface defect) of varying severity. The identified frequency ranges related to squats agree with those found in an extensively validated vehicle-borne detection system. Therefore, the FRF-based statistical method in combination with the non-destructive hammer test measurements has the potential to be employed to identify the characteristic frequencies of damaged conditions in railway tracks in the frequency range of 300-3000 Hz.

Potential improvement of Schmidt-hammer exposure-age dating (SHD) of moraines in the Southern Alps, New Zealand, by application of the new electronic Schmidt-hammer (SilverSchmidt)

NASA Astrophysics Data System (ADS)

Winkler, Stefan; Corbett, David

2014-05-01

The Southern Alps of New Zealand are among the few key study sites for investigating Holocene glacier chronologies in the mid-latitudinal Southern Hemisphere. Their characteristic highly dynamic geomorphological process systems prove, however, to be a considerable challenge for all attempts to date and palaeoclimatologically interpret the existing Holocene moraines record. As a multi-proxy approach combining 10Be terrestrial cosmogenic nuclide dating (TCND) with Schmidt-hammer testing, the recently developed Schmidt-hammer exposure-age dating (SHD) has already shown its potential in this study area (cf. Winkler 2005, 2009, 2013). 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, in particular, facilities for much easier data processing and constitutes 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 - is a potential drawback. This difference effectively means that measurements from the two instruments are not easily interconvertible and, hence, that the instruments cannot be used interchangeably without previous comparative tests of both instruments under field conditions. Both instruments used in this comparative study were N-type models with identical impact energy of 2.207 Nm for the plunger. To compare both instruments and explore interconvertibility, parallel measurements were performed on a selected number of boulders (10 boulders per site with 5 impacts each, at least 2 sites per moraine) on moraines of homogeneous lithology but different established ages covering the entire Holocene and the Late Glacial. All moraines are located east of the Main Divide of the Southern Alps at Mueller Glacier, Tasman Glacier, and in the outer Tasman River Valley. All paired samples (n = 50) were

If the British allocation for overseas aid is increased more generous agreements could be made with host universities and with expatriate staff. It would greatly stimulate overseas service by specialist trainees if the professional colleges and the universities agreed that they would be willing to substitute in their training programmes a year or two of service in an overseas medical school for one or more of their orthodox appointments. Consideration might be given by the councils for postgraduate education to ways of facilitating service overseas by specialist trainees and young consultants. The suggestion of the Royal Commission for the expansion of departmental staff establishments and training pools requires that the temporary expatriate occupying a supernumerary post is absorbed into the establishment on his return. While this may be done now in individual cases by personal arrangement a national agreement between universities and the N.H.S. would be necessary for these secondments to be made on the large scale commensurate to the need.

Water hammer prediction and control: the Green's function method

NASA Astrophysics Data System (ADS)

Xuan, Li-Jun; Mao, Feng; Wu, Jie-Zhi

2012-04-01

By Green's function method we show that the water hammer (WH) can be analytically predicted for both laminar and turbulent flows (for the latter, with an eddy viscosity depending solely on the space coordinates), and thus its hazardous effect can be rationally controlled and minimized. To this end, we generalize a laminar water hammer equation of Wang et al. (J. Hydrodynamics, B2, 51, 1995) to include arbitrary initial condition and variable viscosity, and obtain its solution by Green's function method. The predicted characteristic WH behaviors by the solutions are in excellent agreement with both direct numerical simulation of the original governing equations and, by adjusting the eddy viscosity coefficient, experimentally measured turbulent flow data. Optimal WH control principle is thereby constructed and demonstrated.

Numerical and in-situ investigations of water hammer effects in Drava river Kaplan turbine hydropower plants

NASA Astrophysics Data System (ADS)

Bergant, A.; Gregorc, B.; Gale, J.

2012-11-01

This paper deals with critical flow regimes that may induce unacceptable water hammer in Kaplan turbine hydropower plants. Water hammer analysis should be performed for normal, emergency and catastrophic operating conditions. Hydropower plants with Kaplan turbines are usually comprised of relatively short inlet and outlet conduits. The rigid water hammer theory can be used for this case. For hydropower plants with long penstocks the elastic water hammer should be used. Some Kaplan turbine units are installed in systems with long open channels. In this case, water level oscillations in the channels should be carefully investigated. Computational results are compared with results of measurements in recently rehabilitated seven Drava river hydroelectric power plants in Slovenia. Water hammer in the six power plants is controlled by appropriate adjustment of the wicket gates and runner blades closing/opening manoeuvres. Due to very long inflow and outflow open channels in Zlatoličje HPP a special vaned pressure regulating device attenuates extreme pressures in Kaplan turbine flow-passage system and controls unsteady flow in both open channels. Comparisons of results include normal operating regimes. The agreement between computed and measured results is reasonable.

Pressure and wall shear stress in blood hammer - Analytical theory.

Mei, Chiang C; Jing, Haixiao

2016-10-01

We describe an analytical theory of blood hammer in a long and stiffened artery due to sudden blockage. Based on the model of a viscous fluid in laminar flow, we derive explicit expressions of oscillatory pressure and wall shear stress. To examine the effects on local plaque formation we also allow the blood vessel radius to be slightly nonuniform. Without resorting to discrete computation, the asymptotic method of multiple scales is utilized to deal with the sharp contrast of time scales. The effects of plaque and blocking time on blood pressure and wall shear stress are studied. The theory is validated by comparison with existing water hammer experiments. Copyright © 2016.

Zhao, Hongshan; Feng, Guangtong; Yu, Haiye

2018-03-01

There were many technical problems such as serious well deviation, low penetration rate and long drilling cycle in igneous rocks because of its hardness, strong abrasive and poor drillability, which severely influenced the exploration and development process of Junggar basin. Through analyzing the difficulties of gas drilling with roller bits in Well HS 2, conducting the mechanics experiments about igneous rock, and deeply describing the rock-breaking mechanism of air hammer drilling and its adaptability in igneous rocks, air hammer drilling can realize deviation control and fast drilling in igneous rocks of piedmont zone and avoid the wear and fatigue fracture of drilling strings due to its characteristics of low WOB, low RPM and high frequency impact. Through firstly used in igneous rocks of Well HS 201, compared with gas drilling with cone bit, the average penetration rate and one-trip footage of air hammer drilling respectively increased by more than 2.45 times and 6.42 times while the well deviation was always controlled less than 2 degrees. Two records for Block HS were set up such as the fastest penetration rate of 14.29m/h in Φ444.5mm well hole and the highest one-trip footage of 470.62m in Φ311.2mm well hole. So air hammer drilling was an effective way to realize optimal and fast drilling in the igneous rock formation of Junggar basin.

Computerized Hammer Sounding Interpretation for Concrete Assessment with Online Machine Learning.

Developing efficient Artificial Intelligence (AI)-enabled systems to substitute the human role in non-destructive testing is an emerging topic of considerable interest. In this study, we propose a novel hammering response analysis system using online machine learning, which aims at achieving near-human performance in assessment of concrete structures. Current computerized hammer sounding systems commonly employ lab-scale data to validate the models. In practice, however, the response signal patterns can be far more complicated due to varying geometric shapes and materials of structures. To deal with a large variety of unseen data, we propose a sequential treatment for response characterization. More specifically, the proposed system can adaptively update itself to approach human performance in hammering sounding data interpretation. To this end, a two-stage framework has been introduced, including feature extraction and the model updating scheme. Various state-of-the-art online learning algorithms have been reviewed and evaluated for the task. To conduct experimental validation, we collected 10,940 response instances from multiple inspection sites; each sample was annotated by human experts with healthy/defective condition labels. The results demonstrated that the proposed scheme achieved favorable assessment accuracy with high efficiency and low computation load.

Recent studies of post-war chronic disease epidemiology have generally focused on the histories of research in the USA and UK. Using the archival records of a major British funding body, the Colonial Medical Research Committee and its successor the Tropical Medical Research Board, this article demonstrates the advantages of bringing a post-colonial analytic to this historiography. It highlights how the administrative and medical interests in population difference at the centre of the new epidemiology came to map onto political apparatus initially created to know, reform and govern colonial subjects. Although detached from imperial aims, British medical scientists nonetheless attached value to colonial populations on the basis of British benefit and turned various sites into laboratories to extract it. This relationship did not die with the end of imperial rule. British scientists continued to pursue chronic disease epidemiology in former colonies well into the post-war period, informing debates about Britain's own public health concerns.

An Analysis of the Impact of Valve Closure Time on the Course of Water Hammer

NASA Astrophysics Data System (ADS)

Kodura, Apoloniusz

2016-06-01

The knowledge of transient flow in pressure pipelines is very important for the designing and describing of pressure networks. The water hammer is the most common example of transient flow in pressure pipelines. During this phenomenon, the transformation of kinetic energy into pressure energy causes significant changes in pressure, which can lead to serious problems in the management of pressure networks. The phenomenon is very complex, and a large number of different factors influence its course. In the case of a water hammer caused by valve closing, the characteristic of gate closure is one of the most important factors. However, this factor is rarely investigated. In this paper, the results of physical experiments with water hammer in steel and PE pipelines are described and analyzed. For each water hammer, characteristics of pressure change and valve closing were recorded. The measurements were compared with the results of calculations perfomed by common methods used by engineers - Michaud's equation and Wood and Jones's method. The comparison revealed very significant differences between the results of calculations and the results of experiments. In addition, it was shown that, the characteristic of butterfly valve closure has a significant influence on water hammer, which should be taken into account in analyzing this phenomenon. Comparison of the results of experiments with the results of calculations? may lead to new, improved calculation methods and to new methods to describe transient flow.

A Universal Rig for Supporting Large Hammer Drills: Reduced Injury Risk and Improved Productivity

Drilling holes into concrete with heavy hammer and rock drills is one of the most physically demanding tasks performed in commercial construction and poses risks for musculoskeletal disorders, noise induced hearing loss, hand arm vibration syndrome and silicosis. The aim of this study was to (1) use a participatory process to develop a rig to support pneumatic rock drills or large electric hammer drills in order to reduce the health risks and (2) evaluate the usability of the rig. Seven prototype rigs for supporting large hammer drills were developed and modified with feedback from commercial contractors and construction workers. The final design was evaluated by laborers and electricians (N=29) who performed their usual concrete drilling with the usual method and the new rig. Subjective regional fatigue was significantly less in the neck, shoulders, hands and arms, and lower back) when using the universal rig compared to the usual manual method. Usability ratings for the rig were significantly better than the usual method on stability, control, drilling, accuracy, and vibration. Drilling time was reduced by approximately 50% with the rig. Commercial construction contractors, laborers and electricians who use large hammer drills for drilling many holes should consider using such a rig to prevent musculoskeletal disorders, fatigue, and silicosis.

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.

We claim a hammer driven actuator that uses the fast-motion, low-force characteristics of an electro-magnetic or similar prime mover to develop kinetic energy that can be transformed via a friction interface to produce a higher-force, lower-speed linear or rotary actuator by using a hammering process to produce a series of individual steps. Such a system can be implemented using a voice-coil, electro-mechanical solenoid or similar prime mover. Where a typical actuator provides limited range of motion or low force, the range of motion of a linear or rotary impact driven motor can be configured to provide large displacements which are not limited by the characteristic dimensions of the prime mover.

Migration of medical practitioners is rarely studied despite its importance in medical demography: the objective of this study was to analyze the characteristics and motivations of the French doctors settled in the United Kingdom and of the British doctors settled in France. This cross-sectional study was conducted using a self-completed questionnaire sent to all French doctors practicing in the United Kingdom (in 2005) and all British medicine doctors practicing in France (in 2009). The doctors were identified with official data from the National Medical Councils: 244 French doctors practicing in the United Kingdom and 86 British doctors practicing in France. The questionnaire was specifically developed to determine the reasons of moving to the other country, and the level of satisfaction after expatriation. A total of 98 French doctors (out of 244) and 40 British doctors (out of 86) returned the questionnaire. Respondents were mainly general practitioners with a professional experience of 8 to 9 years. The sex ratio was near 1 for both groups with a majority of women among physicians under 50 years. The motivations were different between groups: French doctors were attracted by the conditions offered at the National Health Service, whereas British doctors were more interested in opportunities for career advancement, joining husband or wife, or favourable environmental conditions. Overall, the respondents considered expatriation as satisfactory: 84% of French doctors, compared with only 58% of British doctors, were satisfied with their new professional situation. This study, the first in its kind, leads to a clearer understanding of the migration of doctors between France and the United Kingdom. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Neutral Caregivers or Military Support? The British Red Cross, the Friends’ Ambulance Unit, and the Problems of Voluntary Medical Aid in Wartime

PubMed Central

2015-01-01

During the First World War the British Red Cross Society (BRCS) served as the coordinating body for voluntary medical aid giving in Britain. Among the many units which came within its purview was the Friends’ Ambulance Unit (FAU), formed by a group of young men whose desire to serve their nation in wartime conflicted with their pacifist principles. Both the BRCS and the FAU were wracked by ideological conflicts in the years which preceded and throughout the war. These struggles over voluntarist identity highlight the contested meanings of service and conscience in wartime. Through a critical examination of the language of official histories and biographies, this article will argue that the war formed a key moment in the relationship between the British state and voluntary medical aid, with the state’s increasing role in the work of such organizations raising questions about the voluntarist principles to which aid organizations laid claim. The struggles that both organizations and individuals within them faced in reconciling the competing pressures that this new relationship created form a legacy of the war which continues to have important implications for the place of medical voluntarism in wartime today.

Finding a Space for Women: The British Medical Association and Women Doctors in Australia, 1880–1939

2018-01-01

This paper examines the experiences of women in one professional organisation – the British Medical Association in Australia – during a significant period in the development of such bodies. In doing so it offers an opportunity to consider the relationship between professional societies and the construction of a gendered profession. For the medical profession in particular the time-frame of this study, from the 1880s to the 1930s, has been regarded by scholars as especially important. In this period various features of medical professionalism came to prominence: the status and authority of doctors, the processes of formally registering medical credentials, and the scope and cohesiveness of professional associations. Taking the third of these themes, the current paper extends previous analyses by uniting gender with history and medicine as the central point of examination, in order to evaluate the changing and contested positions of women within the profession. In this way we not only demonstrate how the history of professional societies can reveal the diverse beliefs and shifting priorities of their members, but also contribute to explaining the remarkable persistence of gendered differences in the medical profession.

These 'frozen' specimens are helpful in examining the plastic deformation that occurs in the regions of compression and shear which form the chip; the secondary shear at the tool-chip interface; and the nose ploughing/flank rubbing action which operates on the newly machined surface. The Hammer QSD employs a shear pin mechanism, broken by a flying hammer, which is traveling at the same velocity as the workpiece. The device has been successfully tested up to 6000 sfpm (30.48 m/sec).

Oscillatory acceleration and deceleration of a column of water leads to a pipe hammer as well as cavitation. With a small amount of xenon gas dissolved in the water, we can detect a stream of predominantly ultraviolet subnanosecond flashes of light which are attributed to collapsing bubbles. The observed emission can exceed 108 photons for a single collapse and has a peak power over 0.4 W.

Every day hundreds of tests are run on the Worldwide LHC Computing Grid for the ATLAS, and CMS experiments in order to evaluate the performance and reliability of the different computing sites. All this activity is steered, controlled, and monitored by the HammerCloud testing infrastructure. Sites with failing functionality tests are auto-excluded from the ATLAS computing grid, therefore it is essential to provide a detailed and well organized web interface for the local site administrators such that they can easily spot and promptly solve site issues. Additional functionality has been developed to extract and visualize the most relevant information. The site administrators can now be pointed easily to major site issues which lead to site blacklisting as well as possible minor issues that are usually not conspicuous enough to warrant the blacklisting of a specific site, but can still cause undesired effects such as a non-negligible job failure rate. This paper summarizes the different developments and optimizations of the HammerCloud web interface and gives an overview of typical use cases.

Tropical skin diseases in British military personnel.

Bailey, Mark S

2013-09-01

Skin complaints are common in travellers to foreign countries and are responsible for up to 25% of medical consultations by military personnel during deployments in the tropics. They also have relatively high rates of field hospital admission, medical evacuation and referral to UK Role 4 healthcare facilities. Non-infectious tropical skin diseases include sunburn, heat rash, arthropod bites, venomous bites, contact dermatitis and phytophotodermatitis. During tropical deployments skin infections that commonly occur in military personnel may become more frequent, severe and difficult to treat. Several systemic tropical infections have cutaneous features that can be useful in making early diagnoses. Tropical skin infections such as cutaneous larva migrans, cutaneous myiasis, cutaneous leishmaniasis and leprosy do occur in British troops and require specialist clinical management. This illustrated review focuses on the most significant tropical skin diseases that have occurred in British military personnel in recent years. Clinical management of these conditions on deployments would be improved and medical evacuations could be reduced if a military dermatology 'reach-back' service (including a telemedicine facility) was available.

Key performance indicators (KPI) are tools for assessing process and outcome in systems of health care provision and are an essential component in performance improvement. Although KPI have been used in British military trauma for 10 years, they remain poorly defined and are derived from civilian metrics that do not adjust for the realities of field trauma care. Our aim was to modify current trauma KPI to ensure they more faithfully reflect both the military setting and contemporary evidence in order to both aid accurate calibration of the performance of the British Defence Medical Services and act as a driver for performance improvement. A workshop was convened that was attended by senior, experienced doctors and nurses from all disciplines of trauma care in the British military. "Speciality-specific" KPI were developed by interest groups using evidence-based data where available and collective experience where this was lacking. In a final discussion these were streamlined into 60 KPI covering each phase of trauma management. The introduction of these KPI sets a number of important benchmarks by which British military trauma can be measured. As part of a performance improvement programme, these will allow closer monitoring of our performance and assist efforts to develop, train, and resource British military trauma providers.

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 barleymore » 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).« less

In present study, influence of grinding (hammer and pin mills) and moisture content (range: 6.4-13.6 % dry basis) on the quality traits of coriander powder were investigated. These include grinding parameters, colour parameters, specific heat, thermal conductivity, thermal diffusivity, glass transition temperature, essential oil, total phenolic content, total flavonoid content and DPPH scavenging (%) of coriander powder. For coriander seed, the geometric properties such as major, medium, minor dimensions, geometric mean diameter, arithmetic mean diameter, sphericity, surface area and volume of coriander seeds increased significantly with increasing moisture (6.4-13.6 % db). For coriander powder, the grinding parameters such as average particle size, volume surface mean diameter and volume mean diameter increased significantly with increasing moisture (6.4-13.6 % db). With the grinding method, the colour attributes of coriander powder such as L-value, a-value, b-value, hue angle and browning index varied significantly. It was observed that the specific heat followed second order polynomial relationship with temperature and moisture whereas thermal conductivity varied linearly with temperature and moisture content. The variation of glass transition temperature with moisture can be best represented in quadratic manner. Total flavonoid content (mg QE/g crude seed extract) and DPPH scavenging % activity of coriander powder is significantly affected by grinding methods. A lower value of specific heat was observed for hammer ground coriander powder as compared to pin mill ground coriander powder. The thermal conductivity of hammer mill ground coriander powder was higher as compared to pin mill ground coriander. It was observed that hammer mill yields more fine coriander powder in comparison to pin mill. The browning index was more in hammer mill ground coriander powder.

Hammer drills are used extensively in commercial construction for drilling into concrete for tasks including rebar installation for structural upgrades and anchor bolt installation. This drilling task can expose workers to respirable silica dust and noise. The aim of this pilot study was to evaluate the effects of bit wear on respirable silica dust, noise, and drilling productivity. Test bits were worn to three states by drilling consecutive holes to different cumulative drilling depths: 0, 780, and 1560 cm. Each state of bit wear was evaluated by three trials (nine trials total). For each trial, an automated laboratory test bench system drilled 41 holes 1.3 cm diameter, and 10 cm deep into concrete block at a rate of one hole per minute using a commercially available hammer drill and masonry bits. During each trial, dust was continuously captured by two respirable and one inhalable sampling trains and noise was sampled with a noise dosimeter. The room was thoroughly cleaned between trials. When comparing results for the sharp (0 cm) versus dull bit (1560 cm), the mean respirable silica increased from 0.41 to 0.74 mg m-3 in sampler 1 (P = 0.012) and from 0.41 to 0.89 mg m-3 in sampler 2 (P = 0.024); levels above the NIOSH recommended exposure limit of 0.05 mg m-3. Likewise, mean noise levels increased from 112.8 to 114.4 dBA (P < 0.00001). Drilling productivity declined with increasing wear from 10.16 to 7.76 mm s-1 (P < 0.00001). Increasing bit wear was associated with increasing respirable silica dust and noise and reduced drilling productivity. The levels of dust and noise produced by these experimental conditions would require dust capture, hearing protection, and possibly respiratory protection. The findings support the adoption of a bit replacement program by construction contractors. © The Author 2017.

HammerCloud was designed and born under the needs of the grid community to test the resources and automate operations from a user perspective. 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.

S71-43788 (2 Aug. 1971) --- Astronaut David R. Scott, Apollo 15 commander, watches a geological hammer and a feather hit the lunar surface simultaneously in a test of Galileo's law of motion concerning falling bodies, as seen in this color reproduction taken from a transmission made by the RCA color television camera mounted on the Lunar Roving Vehicle (LRV). Scott released the hammer from his right hand and the feather from his left at the same instant. Galileo (1564-1642) was the great Italian astronomer and physicist. This experiment occurred toward the end of the third and final lunar surface extravehicular activity (EVA) by astronauts Scott and James B. Irwin, lunar module pilot. While Scott and Irwin descended in the Lunar Module (LM) to explore the moon, astronaut Alfred M. Worden, command module pilot, remained in the Command and Service Modules (CSM) in lunar orbit.

This history of the disease categories "yaws" and "syphilis" explores the interplay between European and African medical cultures in the early modern Atlantic world. The assertion made by both early modern and modern medical authorities, that yaws and syphilis are the same disease, prompts a case study of the history of disease that reflects on a variety of issues in the history of medicine: the use of ideas about contagion to demarcate racial and sexual difference at sites around the British Empire; the contrast between persistently holistic ideas about disease causation in the Black Atlantic and the growth of ontological theories of disease among Europeans and Euro-Americans; and the controversy over the African practice of yaws inoculation, which may once have been an effective treatment but was stamped out by plantation owners who viewed it as a waste of their enslaved laborers' valuable time.

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

Richards, E. J.; Carr, I.; Westcott, M.

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.

To describe the physical activity (PA) levels and counseling attitudes of Canadian undergraduate medical students. Online or paper survey. The University of British Columbia (UBC). Fourth-year medical students at UBC from 2007 to 2010. Physical activity levels, relationship between exercise behaviour and attitudes toward counseling, and student perception of training in the area of exercise prescription. A total of 546 out of 883 students participated in the survey (62% response rate). Sixty-four percent of students met the Canadian Society for Exercise Physiology 2011 recommendations for PA. Attitudes toward healthy living were related to PA levels, but the rate of counseling patients about exercise was not; however, students who engaged in more strenuous PA were more likely to perceive exercise counseling as being highly relevant to future clinical practice (P = .018). Overall, 69% of students perceived exercise counseling to be highly relevant to clinical practice, but 86% thought that their training in this area was less than extensive. Fourth-year UBC medical students engage in more strenuous PA than average age-matched Canadians, which affects their attitudes toward perceived future counseling practices. Encouraging more student participation in strenuous PA and encouraging academic training in the area of exercise counseling might be important next steps in preparing future physicians to effectively prescribe exercise to their patients.

Water hammer reduces fouling during natural water ultrafiltration.

Today's ultrafiltration processes use permeate flow reversal to remove fouling deposits on the feed side of ultrafiltration membranes. We report an as effective method: the opening and rapid closing of a valve on the permeate side of an ultrafiltration module. The sudden valve closure generates pressure fluctuations due to fluid inertia and is commonly known as "water hammer". Surface water was filtrated in hollow fiber ultrafiltration membranes with a small (5%) crossflow. Filtration experiments above sustainable flux levels (>125 l (m2h)(-1)) show that a periodic closure of a valve on the permeate side improves filtration performance as a consequence of reduced fouling. It was shown that this effect depends on flux and actuation frequency of the valve. The time period that the valve was closed proved to have no effect on filtration performance. The pressure fluctuations generated by the sudden stop in fluid motion due to the valve closure are responsible for the effect of fouling reduction. High frequency recording of the dynamic pressure evolution shows water hammer related pressure fluctuations to occur in the order of 0.1 bar. The pressure fluctuations were higher at higher fluxes (higher velocities) which is in agreement with the theory. They were also more effective at higher fluxes with respect to fouling mitigation.

Comparison of Amplitudes and Frequencies of Explosive vs. Hammer Seismic Sources for a 1-km Seismic Line in West Texas

NASA Astrophysics Data System (ADS)

2016-12-01

In May 2016, the National Seismic Source Facility (NSSF) located at the University of Texas at El Paso (UTEP) Department of Geological Sciences collected seismic data at the Indio Ranch located 30 km southwest of Van Horn, Texas. Both hammer on an aluminum plate and explosive sources were used. The project objective was to image subsurface structures at the ranch, owned by UTEP. Selecting the appropriate seismic source is important to reach project objectives. We compare seismic sources between explosions and hammer on plate, focusing on amplitude and frequency. The seismic line was 1 km long, trending WSW to ENE, with 200 4.5 Hz geophones at 5m spacing and shot locations at 10m spacing. Clay slurry was used in shot holes to increase shot coupling around booster. Trojan Spartan cast boosters (150g) were used in explosive sources in each shot hole (1 hole per station). The end of line shots had 5 shot holes instead of 1 (750g total). The hammer source utilized a 5.5 kg hammer and an aluminum plate. Five hammer blows were stacked at each location to improve signal-to-noise ratio. Explosive sources yield higher amplitude, but lower frequency content. The explosions exhibit a higher signal-to-noise ratio, allowing us to recognize seismic energy deeper and farther from the source. Hammer sources yield higher frequencies, allowing better resolution at shallower depths but have a lower signal-to-noise ratio and lower amplitudes, even with source stacking. We analyze the details of the shot spectra from the different types of sources. A combination of source types can improve data resolution and amplitude, thereby improving imaging potential. However, cost, logistics, and complexities also have a large influence on source selection.

Unpalatable Truths: Food and Drink as Medicine in Colonial British India.

PubMed

Goodman, Sam

2018-04-01

This article considers the significance of eating and drinking within a series of diaries and journals produced in British colonial India during the Indian Rebellion of 1857. The discussion of food and drink in this context was not simply a means to add color or compelling detail to these accounts, but was instead a vital ingredient of the authors' understanding of health and medical treatment. These texts suggest a broader colonial medical understanding of the importance of regulating diet to maintain physical health. Concern with food, and the lack thereof, was understandably a key element in diaries, and in the eyewitness accounts kept by British soldiers, doctors, and civilians during the rebellion. At a narrative level, mention of food also functioned as a trope serving to increase dramatic tension and to capture an imagery of fortitude. In references to drink, by contrast, these sources reveal a conflict between professional and lay opinions regarding the use of alcohol as part of medical treatment. The accounts show the persistent use of alcohol both for medicinal and restorative purposes, despite growing social and medical anxieties over its ill-effects on the body. Close examination of these references to food and drink reflect the quotidian habits, social composition, and the extent of professional and lay knowledge of health and medicine in colonial British India.

Crushing is a key step during olive oil extraction. Among commercial crushers, the hammer mill is the most widely used due to its robustness and high throughput. In the present work, the impact of hammer mill rotor speed on extraction yield and overall quality of super-high-density Arbosana olive oils were assessed in an industrial facility. Our results show that increasing the rotor speed from 2400rpm to 3600rpm led to a rise in oil yield of 1.2%, while conserving quality parameters. Sensory analysis showed more pungency with increased rotation speed, while others attributes were unaffected. Volatile compounds showed little variation with the differences in crusher speed; however, total phenols content, two relevant secoiridoids, and triterpenoids levels increased with rotor speed. Hammer mill rotor speed is a processing variable that can be tuned to increase the extraction efficiency and modulate the chemical composition of extra virgin olive oil.

Anisotropy in Alpedrete granite cutting (Rift, Grain and Hardway directions) and effect on bush hammered heritage ashlars

NASA Astrophysics Data System (ADS)

Freire-Lista, David Martin; Fort, Rafael

2015-04-01

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

Naive, captive long-tailed macaques (Macaca fascicularis fascicularis) fail to individually and socially learn pound-hammering, a tool-use behaviour

PubMed Central

Tennie, Claudio

2018-01-01

A subspecies of long-tailed macaques (Macaca fascicularis aurea; Mfa) has been reported to use stone tools and a specific technique to process nuts in Southeast Asia, a behaviour known as ‘pound-hammering’. The aim of this study was to examine the development of pound-hammering in long-tailed macaques: whether this behavioural form can be individually learnt or whether it has to rely on some forms of social learning. Given the absence of Mfa from captivity, long-tailed macaques of a highly related subspecies (Macaca fascicularis fascicularis; Mff) were experimentally tested by providing them with the ecological materials necessary to show pound-hammering. A baseline was first carried out to observe whether pound-hammering would emerge spontaneously without social information. As this was not the case, different degrees of social information, culminating in a full demonstration of the behaviour, were provided. None of the subjects (n = 31) showed pound-hammering in any of the individual or social learning conditions. Although these data do not support the hypothesis that individual learning underlies this behaviour, no evidence was found that (at least) Mff learn pound-hammering socially either. We propose that other—potentially interacting—factors may determine whether this behaviour emerges in the various subspecies of long-tailed macaques, and provide a novel methodology to test the role of social and individual learning in the development of animal tool-use.

Hypothenar hammer syndrome: a case and brief review.

PubMed

Swanson, Keith E; Bartholomew, John R; Paulson, Rolf

2012-04-01

Hypothenar hammer syndrome is an uncommon cause of upper-extremity ischemia that is often overlooked in the absence of a thorough occupational and recreational history. Importantly, it is a reversible cause of hand ischemia that, if missed, can lead to significant morbidity and even amputation. The occupational ramifications and quality of life of those affected can be significant. Its relative rarity, set against the ubiquitous use of the hand as a 'hammer' is noteworthy. Several other causes of hand ischemia can present similarly; therefore, consideration of other etiologies must be thoroughly investigated. Key distinguishing clinical features, in addition to a detailed occupational and recreational history, may include characteristic sparing of the thumb, the absence of a hyperemic phase in 'Raynaud's phenomenon', and a positive Allen's sign. Both non-invasive and invasive diagnostic studies, including bilateral upper-limb segmental pulse volume recordings (PVR), arterial duplex examination, and upper-extremity angiography, are complementary to a thorough history and physical examination. Optimal management strategies are not well defined because of its rarity and resultant lack of quality, evidence-based data. Though most cases can be successfully managed non-operatively, micrographic arterial reconstruction may be limb saving in severe or recalcitrant cases. Newer, experimental strategies including selective sympathetic blockage using botulinum toxin A have been reported in a few recalcitrant cases. The brief case description illustrates the typical presentation and potential treatment strategies employed in a difficult case. A review of relevant literature is also presented.

Subsurface sediment contamination during borehole drilling with an air-actuated down-hole hammer.

PubMed

Malard, Florian; Datry, Thibault; Gibert, Janine

2005-10-01

Drilling methods can severely alter physical, chemical, and biological properties of aquifers, thereby influencing the reliability of water samples collected from groundwater monitoring wells. Because of their fast drilling rate, air-actuated hammers are increasingly used for the installation of groundwater monitoring wells in unconsolidated sediments. However, oil entrained in the air stream to lubricate the hammer-actuating device can contaminate subsurface sediments. Concentrations of total hydrocarbons, heavy metals (Cu, Ni, Cr, Zn, Pb, and Cd), and nutrients (particulate organic carbon, nitrogen, and phosphorus) were measured in continuous sediment cores recovered during the completion of a 26-m deep borehole drilled with a down-hole hammer in glaciofluvial deposits. Total hydrocarbons, Cu, Ni, Cr and particulate organic carbon (POC) were all measured at concentrations far exceeding background levels in most sediment cores. Hydrocarbon concentration averaged 124 +/- 118 mg kg(-1) dry sediment (n = 78 samples) with peaks at depths of 8, 14, and 20 m below the soil surface (maximum concentration: 606 mg kg(-1)). The concentrations of hydrocarbons, Cu, Ni, Cr, and POC were positively correlated and exhibited a highly irregular vertical pattern, that probably reflected variations in air loss within glaciofluvial deposits during drilling. Because the penetration of contaminated air into the formation is unpreventable, the representativeness of groundwater samples collected may be questioned. It is concluded that air percussion drilling has strong limitations for well installation in groundwater quality monitoring surveys.

With the increased development of distributed sites for medical education across Canada, it is imperative we ensure that the quality of education is comparable between the different campuses. Our objective was to assess medical student experience and comfort with common urologic clinical encounters and to determine whether any differences exist between the distributed education sites at the University of British Columbia (UBC). Questionnaires assessing urologic education were delivered simultaneously to all final-year UBC medical students attending campuses in Vancouver, Victoria and Prince George. Results were analyzed using descriptive statistics. Overall, 55.8% of students felt their exposure to urology was adequate in the medical curriculum; learners in the Northern Program (Prince George) ranked their clinical and didactic experiences significantly higher. Areas requiring improvement include teaching of the male genitourinary exam, digital rectal exam and sexual history, in which learners rated teaching "good/outstanding" in only 18.2%, 47.7% and 43.2% of cases, respectively. Overall, students were most comfortable with the following clinical encounters: urinary tract infection, nephrolithiasis, benign prostatic hyperplasia, hematuria, incontinence and prostate cancer. Few differences in student experience or comfort were noted related to campus site, gender or urology clerkship exposure. A significant minority of learners perceived that they had inadequate exposure to urology in the undergraduate curriculum. Experience in urology was comparable across the distributed sites and was congruent with teaching objectives. Students were comfortable with the clinical scenarios deemed most important in the literature. Learners in the Northern Program were significantly more satisfied with their urologic teaching, which potentially highlights the advantages of learning in a smaller academic setting.

Vertebrobasilar dolichoectasia is a clinical entity associated rarely with obstructive hydrocephalus. We present a 48-year old male with a profound dilatation of the ventricular system due to a dolichoectatic basilar artery, as appeared in imaging studies. The patient suffered from longstanding hydrocephalus and presenile dementia. The underlying mechanism for obstructive hydrocephalus due to vertebrobasilar dolichoectasia is considered to be both a water-hammer effect and a direct compression of adjacent structures. We suggest prompt surgical intervention upon diagnosis as a first choice treatment in order to avoid further complications. PMID:26236456

To determine the association between systemic medication use and intraocular pressure (IOP) in a population of older British men and women. Population-based, cross-sectional study. We included 7093 participants from the European Prospective Investigation into Cancer-Norfolk Eye Study. Exclusion criteria were a history of glaucoma therapy (medical, laser, or surgical), IOP asymmetry between eyes of >5 mmHg, and missing data for any covariables. The mean age of participants was 68 years (range, 48-92) and 56% were women. We measured IOP using the Ocular Response Analyzer. Three readings were taken per eye and the best signal value of the Goldmann-correlated IOP value considered. Participants were asked to bring all their medications and related documentation to the health examination, and these were recorded by the research nurse using an electronic case record form. The medication classes examined were angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, α-blockers, β-blockers, calcium channel blockers, diuretics, nitrates, statins, insulin, biguanides, sulfonylureas, aspirin, and other nonsteroidal anti-inflammatory drugs. We examined associations between medication use and IOP using multivariable linear regression models adjusted for age, sex, and body mass index. Models containing diabetic medication were further adjusted for glycosylated hemoglobin levels. Mean IOP of the right and left eyes. Use of systemic β-blockers (-0.92 mmHg; 95% CI, -1.19, -0.65; P<0.001) and nitrates (-0.63 mmHg; 95% CI, -1.12, -0.14; P = 0.011) were independently associated with lower IOP. The observed associations between statin or aspirin use with IOP were no longer significant after adjustment for β-blocker use. This is the first population-based study to demonstrate and quantify clinically significant differences in IOP among participants using systemic β-blockers or nitrates. Lower IOP observed in participants using statins or aspirin was explained by

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.

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.

Numerical investigation of soil plugging effect inside sleeve of cast-in-place piles driven by vibratory hammers in clays.

PubMed

Xiao, Yong Jie; Chen, Fu Quan; Dong, Yi Zhi

2016-01-01

During driving sleeve of cast-in-place piles by vibratory hammers, soils were squeezed into sleeve and then soil plugging was formed. The physic-mechanical properties of the soil plug have direct influence on the load transmission between the sleeve wall and soil plug. Nevertheless, the researches on this issue are insufficient. In this study, finite element and infinite element coupling model was introduced, through the commercial code ABAQUS, to simulate the full penetration process of the sleeve driven from the ground surface to the desired depth by applying vibratory hammers. The research results indicated that the cyclic shearing action decreases both in soil shear strength and in granular cementation force when the sleeve is driven by vibratory hammers, which leads to a partially plugged mode of the soil plug inside the sleeve. Accordingly, the penetration resistance of sleeve driven by vibratory hammers is the smallest compared to those by other installation methods. When driving the sleeve, the annular soil arches forming in the soil plug at sleeve end induce a significant rise in the internal shaft resistance. Moreover, the influence of vibration frequencies, sleeve diameters, and soil layer properties on the soil plug was investigated in detail, and at the same time improved formulas were brought forward to describe the soil plug resistance inside vibratory driven sleeve.

In this work effect of the impact location and the type of hammer tip on the frequency response function (FRF) is studied. Experimental modal analysis of rectangular plates is carried out for this purpose by using impact hammer, accelerometer and fast Fourier transform (FFT) analyzer. It is observed that the impulse hammer hit location has, no effect on the eigenfrequency, yet a difference in amplitude of the eigenfrequencies is obtained. The effect of the hammer tip on the pulse and the force spectrum is studied for three types of tips metal, plastic and rubber. A solid rectangular plate was excited by using these tips one by one in three different tests. It is observed that for present experimental set up plastic tip excites the useful frequency range.

Objectives Options associated with geothermal drilling operations are generally limited by factors such as formation temperature and rock strength. The objective of the research is to expand the "tool box" available to the geothermal driller by furthering the development of a high-temperature drilling motor that can be used in directional drilling applications for drilling high temperature geothermal formations. The motor is specifically designed to operate in conjunction with a pneumatic down-the-hole-hammer. It provides a more compact design compared to traditional drilling motors such as PDMs (positive displacement motors). The packaging can help to enhance directional drilling capabilities. It uses no elastomeric components, which enables it to operate in higher temperatures ( >250 °F). Current work on the motor has shown that is a capable of operating under pneumatic power with a down-the-hole-hammer. Further development work will include continued testing and refining motor components and evaluating motor capabilities. Targets/Milestones Complete testing current motor - 12/31/2010 Make final material and design decisions - 01/31/2011 Build and test final prototype - 04/31/2011 Final demonstration - 07/31/2011 Impacts The development of the motor will help to achieve program technical objectives by improving well construction capabilities. This includes enabling high-temperature drilling as well as enhancing directional drilling. A key component in the auto indexer is the drive motor. It is an air-driven vane motor that converts the energy stored in the compressed air to mechanical energy. The motor is attached to hammer-like components which impart an impulsive load onto the drive shaft. The impulsive force on the drive shaft in turn creates an indexing action. A controlled test was performed to characterize the performance of the the vane motor for a given pressure. The Sandia dynamometer test station was used to determine the performance of the motor for a

Rapid horizontal directional well drilling in hard or fractured formations requires efficient drilling technology. The penetration rate of conventional hard rock drilling technology in horizontal directional well excavations is relatively low, resulting in multiple overgrinding of drill cuttings in bottom boreholes. Conventional drilling techniques with reamer or diamond drill bit face difficulties due to the long construction periods, low penetration rates, and high engineering costs in the directional well drilling of hard rock. To improve the impact energy and penetration rate of directional well drilling in hard formations, a new drilling system with a percussive and rotary drilling technology has been proposed, and a hydro-hammer with a jet actuator has also been theoretically designed on the basis of the impulse hydro-turbine pressure model. In addition, the performance parameters of the hydro-hammer with a jet actuator have been numerically and experimentally analyzed, and the influence of impact stroke and pumped flow rate on the motion velocity and impact energy of the hydro-hammer has been obtained. Moreover, the designed hydro-hammer with a jet actuator has been applied to hard rock drilling in a trenchless drilling program. The motion velocity of the hydro-hammer ranges from 1.2 m/s to 3.19 m/s with diverse flow rates and impact strokes, and the motion frequency ranges from 10 Hz to 22 Hz. Moreover, the maximum impact energy of the hydro-hammer is 407 J, and the pumped flow rate is 2.3 m3/min. Thus, the average penetration rate of the optimized hydro-hammer improves by over 30% compared to conventional directional drilling in hard rock formations.

CFD simulation of reverse water-hammer induced by collapse of draft-tube cavity in a model pump-turbine during runaway process

2016-11-01

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.

"Essentially Christian, eminently philanthropic": the Mission to Lepers in British India.

Joseph, D George

2003-01-01

The early history of the Mission to Lepers in India is an interplay between politics, religion, and medicine in the context of British imperialism. The Mission pursued the dual but inseparable goals of evangelization and civilization, advancing not only a religious program but also a political and cultural one. These activities and their consequences were multi-faceted because while the missionaries pursued their religious calling, they also provided medical care to people and in places that the colonial government was unable or unwilling. Within the context of the British imperial program, the work imparted Western social and cultural ideals on the colonial populations they served, inculcated patients with Christian beliefs, and provided medical care to individuals who had been expelled from their own communities. Physical healing was intimately tied to religious salvation, spiritual healing, and the civilizing process.

Gender, money and professional identity: medical social work and the coming of the British National Health Service.

Gosling, George Campbell

2018-01-01

The arrival of the British National Health Service (NHS) in 1948 heralded significant changes for all health workers, but the establishment of a 'free' health service was especially meaningful for the hospital almoners-or medical social workers, as they were starting to be known-who had previously been responsible for the assessment and collection of patient payments. It was on this basis they had gained a foothold in the hospital, capitalising on gendered assumptions of financial understanding and behaviour. Yet what might have caused an identity crisis was embraced. This was a dual strategy of both repositioning the profession in alignment with the planned NHS and of asserting an enhanced professional status by distancing themselves from the handling of payment. It was an episode in the history of this distinctly female profession that speaks to women's historic relationship with money.

Research on the water hammer protection of the long distance water supply project with the combined action of the air vessel and over-pressure relief valve

NASA Astrophysics Data System (ADS)

Li, D. D.; Jiang, J.; Zhao, Z.; Yi, W. S.; Lan, G.

2013-12-01

We take a concrete pumping station as an example in this paper. Through the calculation of water hammer protection with a specific pumping station water supply project, and the analysis of the principle, mathematical models and boundary conditions of air vessel and over-pressure relief valve we show that the air vessel can protect the water conveyance system and reduce the transient pressure damage due to various causes. Over-pressure relief valve can effectively reduce the water hammer because the water column re-bridge suddenly stops the pump and prevents pipeline burst. The paper indicates that the combination set of air vessel and over-pressure relief valve can greatly reduce the quantity of the air valve and can eliminate the water hammer phenomenon in the pipeline system due to the vaporization and water column separation and re-bridge. The conclusion could provide a reference for the water hammer protection of long-distance water supply system.

Observational study. The BMJ research archive. 160 randomly sampled BMJ research articles from 2009 to 2015, excluding meta-analysis and systematic reviews. Percentages of research articles that indicated the availability of their raw data sets in their data sharing statements, and those that easily made their data sets available on request. 3 articles contained the data in the article. 50 out of 157 (32%) remaining articles indicated the availability of their data sets. 12 used publicly available data and the remaining 38 were sent email requests to access their data sets. Only 1 publicly available data set could be accessed and only 6 out of 38 shared their data via email. So only 7/157 research articles shared their data sets, 4.5% (95% CI 1.8% to 9%). For 21 clinical trials bound by the BMJ data sharing policy, the per cent shared was 24% (8% to 47%). Despite the BMJ's strong data sharing policy, sharing rates are low. Possible explanations for low data sharing rates could be: the wording of the BMJ data sharing policy, which leaves room for individual interpretation and possible loopholes; that our email requests ended up in researchers spam folders; and that researchers are not rewarded for sharing their data. It might be time for a more effective data sharing policy and better incentives for health and medical researchers to share their data. Published by the BMJ Publishing Group Limited.

British Romantic Generalism in the Age of Specialism, 1870–1990

PubMed Central

Casper, Stephen T.; Welsh, Rick

2016-01-01

This essay explores the impact of ‘generalism’ and ‘general practice’ on the specialisation of British medicine using the case of neurology in Britain to reveal characteristics of British ‘generalist medical culture’ from 1870 to 1990. It argues that ‘generalism’ represented a particular epistemological position in Victorian medicine, one that then created a natural bridge between science and medicine over which almost all physicians and scientists were comfortable walking. The legacies of that Victorian ‘generalist preference’ exerted an enduring impact on the specialisation process as physicians experienced it in the twentieth century and as this case of neurology reveals so clearly. Neurologists and general physicians would still be arguing about the relative merits of a general medical education into the 1980s. By then, however, the emergence of government bodies promoting specialist labour conditions would have rendered the process seemingly inexorable. PMID:26858515

Cultural and age differences in beliefs about depression: British Bangladeshis vs. British Whites

2013-01-01

This study examines beliefs about depression as a function of ethnic background (British Bangladeshis vs. British Whites) and age. A total of 364 participants completed a 65-item questionnaire, containing general questions regarding depression and anti-depressive behaviour; the causes of depression, and treatments for depression. The hypotheses were broadly supported; there were significant interactions between ethnicity and age, which generally revealed an increasingly negative attitude towards depression with increasing age amongst British Bangladeshis. Older British Bangladeshis believed depression was an illness that brought a sense of shame and loss of dignity to the individual and his or her family, and they also favoured a lay referral system for sufferers. They also had more superstitious beliefs about depression than both younger British Bangladeshis and British Whites. A pattern of increasing negativity with increasing age was not evident amongst the British Whites, but older individuals in both groups tended to believe that depression was not helped by psychological intervention. The attitudes towards depression in the young was similar (and generally positive) in both ethnic groups. These findings highlight the necessity to provide more culturally sensitive and accessible services for migrant communities – particularly amongst older individuals. PMID:25076835

2014-01-01

This article explores some effects of the British payment for performance model on general practitioners' principles and practice, which may contribute to issues related to financial incentive modalities and quality of primary healthcare services in low and middle-income countries. Aiming to investigate what general practitioners have to say about the effect of the British payment for performance on their professional ethos we carried out semi-structured interviews with 13 general practitioner educators and leaders working in academic medicine across the UK. The results show a shift towards a more biomedical practice model and fragmented care with nurse practitioners and other health care staff focused more on specific disease conditions. There has also been an increased medicalisation of the patient experience both through labelling and the tendency to prescribe medications rather than non-pharmacological interventions. Thus, the British payment for performance has gradually strengthened a scientific-bureaucratic model of medical practice which has had profound effects on the way family medicine is practiced in the UK.

Analysis on shock wave speed of water hammer of lifting pipes for deep-sea mining

NASA Astrophysics Data System (ADS)

Zhou, Zhi-jin; Yang, Ning; Wang, Zhao

2013-04-01

Water hammer occurs whenever the fluid velocity in vertical lifting pipe systems for deep-sea mining suddenly changes. In this work, the shock wave was proven to play an important role in changing pressures and periods, and mathematical and numerical modeling technology was presented for simulated transient pressure in the abnormal pump operation. As volume concentrations were taken into account of shock wave speed, the experiment results about the pressure-time history, discharge-time history and period for the lifting pipe system showed that: as its concentrations rose up, the maximum transient pressure went down, so did its discharges; when its volume concentrations increased gradually, the period numbers of pressure decay were getting less and less, and the corresponding shock wave speed decreased. These results have highly coincided with simulation results. The conclusions are important to design lifting transporting system to prevent water hammer in order to avoid potentially devastating consequences, such as damage to components and equipment and risks to personnel.

Cardiovascular disease mortality in British merchant shipping and among British seafarers ashore in Britain.

The objective was to investigate trends in work-related mortality from cardiovascular disease (CVD) among seafarers employed in British merchant shipping from 1919 to 2005, to compare CVD mortality among British seafarers at work in British shipping - and ashore in Britain - with that in the general British population, and to investigate work-related CVD mortality in British shipping during recent years according to factors such as rank, nationality, location, and type of ship. A longitudinal study based on examination of death inquiry files and death registers, official death returns, and information from occupational mortality decennial supplements. The main outcome measures were population-based mortality rates and standardised mortality ratios. There was an increase in work-related CVD mortality throughout much of the period from 1919 to 1962, but a subsequent reduction to 2005. Work-related mortality from CVD and ischaemic heart disease (IHD) was lower among seafarers employed in British shipping than in the corresponding general population (SMRs = 0.35 to 0.46), but mortality from CVD among British seafarers ashore in Britain was often increased. An elevated risk of work-related CVD mortality was also identified among the crews of North Sea offshore ships. This study shows a healthy worker effect against CVD mortality among seafarers at work in British shipping, but increased risks among British seafarers ashore in Britain, which would include seafarers discharged through CVD morbidity and other illnesses. The high risks of CVD mortality among seafarers in North Sea supply ships may reflect particular work-related hazards in this sector.

Pressure signature and evaluation of hammer pulses during underwater implosion in confining environments.

Gupta, Sachin; Matos, Helio; Shukla, Arun; LeBlanc, James M

2016-08-01

The fluid structure interaction phenomenon occurring in confined implosions is investigated using high-speed three-dimensional digital image correlation (DIC) experiments. Aluminum tubular specimens are placed inside a confining cylindrical structure that is partially open to a pressurized environment. These specimens are hydrostatically loaded until they naturally implode. The implosion event is viewed, and recorded, through an acrylic window on the confining structure. The velocities captured through DIC are synchronized with the pressure histories to understand the effects of confining environment on the implosion process. Experiments show that collapse of the implodable volume inside the confining tube leads to strong oscillating water hammer waves. The study also reveals that the increasing collapse pressure leads to faster implosions. Both peak and average structural velocities increase linearly with increasing collapse pressure. The effects of the confining environment are better seen in relatively lower collapse pressure implosion experiments in which a long deceleration phase is observed following the peak velocity until wall contact initiates. Additionally, the behavior of the confining environment can be viewed and understood through classical water hammer theory. A one-degree-of-freedom theoretical model was created to predict the impulse pressure history for the particular problem studied.

Despite its popular support, the Act was declared unconstitutional by the Supreme Court in Hammer v. Dagenhart (1918). The Court's decision involved several major issues: interpretation of the Fifth and Fourteenth Amendments to the Constitution, freedom of contract, police power of the states, and the interstate commerce clause. Review of previous Court decisions suggests that the justices were on less than solid legal ground in reaching their decision. Examination of the historical context of the decision, however, suggests other factors that may have played a more important role than judicial precedents. The debate prompted by Hammer v. Dagenhart has much relevance to such current issues as young agricultural workers, sex discrimination in industry, and the powers of the federal government vis-a-vis states and individual citizens.

Water hammer caused by closure of turbine safety spherical valves

NASA Astrophysics Data System (ADS)

2010-08-01

This paper investigates water hammer effects caused by closure of spherical valves against the discharge. During the first phase of modernisation of Perućica high-head hydropower plant (HPP), Montenegro, safety spherical valves (inlet turbine valves) have been refurbished on the first two Pelton turbine units. The valve closure is controlled by the valve actuator (hydraulic servomotor). Because the torque acting on the valve body is dependent on flow conditions the valve closing time may vary significantly for different flow velocities (passive valve). For the passive valve the torques acting on the valve body should be considered in the valve model. The valve closing time results from numerical simulation. On the contrary, for the active valve the valve closing time is assumed prior to simulation. The spherical valve boundary condition is incorporated into the method of characteristics (MOC) algorithm. The staggered (diamond) grid in applying the MOC is used in this paper. The passive valve boundary condition is described by the water hammer equations, the valve equation that relates discharge to pressure head drop and the dynamic equation of the valve body motion (torque equation). The active valve boundary condition is described by the first two equations, respectively. Standard quasi-steady friction model is used for estimating friction losses in plant's tunnel and penstocks. Numerical results using both the active and the passive spherical valve models are compared with results of measurements. It has been found that the influence of flow conditions on the spherical valve closing time is minor for the cases considered. Computed and measured results agree reasonably well.

Dynamic Brazilian Test of Rock Under Intermediate Strain Rate: Pendulum Hammer-Driven SHPB Test and Numerical Simulation

NASA Astrophysics Data System (ADS)

Zhu, W. C.; Niu, L. L.; Li, S. H.; Xu, Z. H.

2015-09-01

The tensile strength of rock subjected to dynamic loading constitutes many engineering applications such as rock drilling and blasting. The dynamic Brazilian test of rock specimens was conducted with the split Hopkinson pressure bar (SHPB) driven by pendulum hammer, in order to determine the indirect tensile strength of rock under an intermediate strain rate ranging from 5.2 to 12.9 s-1, which is achieved when the incident bar is impacted by pendulum hammer with different velocities. The incident wave excited by pendulum hammer is triangular in shape, featuring a long rising time, and it is considered to be helpful for achieving a constant strain rate in the rock specimen. The dynamic indirect tensile strength of rock increases with strain rate. Then, the numerical simulator RFPA-Dynamics, a well-recognized software for simulating the rock failure under dynamic loading, is validated by reproducing the Brazilian test of rock when the incident stress wave retrieved at the incident bar is input as the boundary condition, and then it is employed to study the Brazilian test of rock under the higher strain rate. Based on the numerical simulation, the strain-rate dependency of tensile strength and failure pattern of the Brazilian disc specimen under the intermediate strain rate are numerically simulated, and the associated failure mechanism is clarified. It is deemed that the material heterogeneity should be a reason for the strain-rate dependency of rock.

Mapping the field of medical sociology: a comparative analysis of journals.

PubMed

Seale, Clive

2008-07-01

A comparative keyword analysis of the content of nine leading journals is used to suggest potential new directions for medical sociology. The major British and American journals in sociology and medical sociology tend to publish authors based in their own countries, contrasting with the internationalism of other social science disciplines relevant to health, although Sociology of Health and Illness is an exception to this. Medical sociology journals on both sides of the Atlantic focus on individual experience more than general sociology journals, which focus more on social systems levels of analysis. While journal contents reveal British medical sociology to be relatively atheoretical when compared with British general sociology journals, American medical sociology appears relatively apolitical on the same comparison with American general journals. American journals of sociology publish more quantitative studies than their British equivalents, more studies concerning race and other social divisions in American society, and less work drawing on social constructionist perspectives or that is engaged with social theory. Analysis of health and health care at societal and global levels and a deeper engagement with the political and public issues that concern non-sociologists represents a possible future for a medical sociology that is internationally relevant and outward looking.

Kamal, A.A.; Mikael, R.A.; Faris, R.

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 significantlymore » 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.« less

Stable sonoluminescence within a water hammer tube.

Chakravarty, Avik; Georghiou, Theo; Phillipson, Tacye E; Walton, Alan J

2004-06-01

The sonoluminescence (SL) from the collapse of a single gas bubble within a liquid can be produced repetitively using an acoustic resonator. An alternative technique using a water hammer tube, producing SL from bubbles of greater size, is described here. A sealed vertical tube partly filled with a liquid and a gas at low pressure is subjected to vertical vibrations. The oscillation of the pressure within the liquid column, due to inertial forces, excites cavitation bubbles to grow and collapse. Rotation is used to confine the bubbles to the axis of the tube. Bright SL emissions were observed in a number of liquids. Repetitive emission was produced from bubbles in condensed phosphoric acid. Bubbles of 0.4 mm ambient radius (containing 2x 10(14) xenon atoms) were excited by vibration at 35 Hz. Approximately 10(12) photons were emitted per collapse in the range 400-700 nm (over four orders of magnitude greater than the brightest SL reported previously), corresponding to a 1% efficiency of the conversion of mechanical energy into light.

The impact of direct and extra billing for medical services: evidence from a natural experiment in British Columbia.

Epp, M J; Vining, A R; Collins-Dodd, C; Love, E

2000-09-01

This paper examines the impact of direct and extra billing on patient demand for medical services as well as physicians' responses to changing patient demand. These issues are examined in the context of a "natural experiment" in British Columbia, Canada where, in 1992, 81 general practitioners and specialists "opted-out" of the provincial Medical Services Plan (MSP) and began direct and extra billing their patients. These opted-out physicians are compared to a matched sample of physicians who remained within the MSP. Switching costs for patients were relatively low because of the availability of non-direct/extra billing physicians. The data consists of the more than 140,000 patient visit claims over a 2-year time period, one year immediately prior to the opting-out date and one year immediately following. The results of this study show that, on average, female visits to opted-out general practitioners (GPs) dropped approx. 9% after direct/extra billing. There was no concurrent drop for male patient visits. On average, patient visits to opted-out specialists dropped approx. 6%. Within the observed timeframe, opted-out physicians' billing patterns changed; somewhat offsetting this demand decrease. On average, opted-out GPs' payments per remaining patient increased by 10% following direct/extra billing (the post period), while opted-out specialists' payments per patient increased by 7%. There were no corresponding changes in payments per patient for the control group of physicians who remained opted-in.

The drill is expected to operate under different environments including Martian ambient (6 Torr and down to -50 degree C), and liquid nitrogen temperatures (77 K) and low pressure (<<1 Torr) to simulate lunar polar and Europa conditions. Materials expected to be sampled include Kaolinite, Saddleback Basalt, Limestone, Volcanic Breccia, Siltstone, ice, permafrost and layered rocks with different hardness.

Computation of water hammer protection of modernized pumping station

Himr, Daniel

2014-03-01

Pumping station supplies water for irrigation. Maximal capacity 2 × 1.2m3·s-1 became insufficient, thus it was upgraded to 2 × 2m3·s-1. Paper is focused on design of protection against water hammer in case of sudden pumps trip. Numerical simulation of the most dangerous case (when pumps are giving the maximal flow rate) showed that existing air vessels were not able to protect the system and it would be necessary to add new vessels. Special care was paid to influence of their connection to the main pipeline, because the resistance of the connection has a significant impact on the scale of pressure pulsations. Finally, the pump trip was performed to verify if the system worked correctly. The test showed that pressure pulsations are lower (better) than computation predicted. This discrepancy was further analysed.

Variable Step Integration Coupled with the Method of Characteristics Solution for Water-Hammer Analysis, A Case Study

NASA Technical Reports Server (NTRS)

Turpin, Jason B.

2004-01-01

One-dimensional water-hammer modeling involves the solution of two coupled non-linear hyperbolic partial differential equations (PDEs). These equations result from applying the principles of conservation of mass and momentum to flow through a pipe, and usually the assumption that the speed at which pressure waves propagate through the pipe is constant. In order to solve these equations for the interested quantities (i.e. pressures and flow rates), they must first be converted to a system of ordinary differential equations (ODEs) by either approximating the spatial derivative terms with numerical techniques or using the Method of Characteristics (MOC). The MOC approach is ideal in that no numerical approximation errors are introduced in converting the original system of PDEs into an equivalent system of ODEs. Unfortunately this resulting system of ODEs is bound by a time step constraint so that when integrating the equations the solution can only be obtained at fixed time intervals. If the fluid system to be modeled also contains dynamic components (i.e. components that are best modeled by a system of ODEs), it may be necessary to take extremely small time steps during certain points of the model simulation in order to achieve stability and/or accuracy in the solution. Coupled together, the fixed time step constraint invoked by the MOC, and the occasional need for extremely small time steps in order to obtain stability and/or accuracy, can greatly increase simulation run times. As one solution to this problem, a method for combining variable step integration (VSI) algorithms with the MOC was developed for modeling water-hammer in systems with highly dynamic components. A case study is presented in which reverse flow through a dual-flapper check valve introduces a water-hammer event. The predicted pressure responses upstream of the check-valve are compared with test data.

"A midwife at every confinement": Midwifery and Medicalized Childbirth in Ontario and Britain, 1920-1950.

PubMed

Cross, Gwenith Siobhan

2014-01-01

This paper compares midwifery in Ontario and Britain in the first half of the 20th century. British midwives improved maternal and infant health and welfare by making childbirth a cooperative, medically managed event in conjunction with physicians. British midwives thus participated in, and contributed to, developments in obstetrics. In contrast, Ontario physicians worked to exclude midwives from participation in the modernization of birth management, relying on a narrower concept of "medicalization" defined as physician dominance. This study challenges the medical profession's assumptions that the exclusion of midwifery in Ontario was necessary to the medicalization of childbirth. The British alternative, where midwives were seen as partners rather than obstacles, illustrates that medicalization in the interest of infant and maternal safety could be integrated with the work of midwives.

2013-04-01

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.

A pseudo-outbreak of skin disease in British troops.

When a newspaper report claimed that a serious outbreak of skin disease had occurred in British Army troops stationed at the Bocac Dam, in western Bosnia, all troops at the Bocac Dam location (n = 96), followed by a matched control group of troops (n = 91) at a nearby location, were examined by two investigators. 14% of the study population and 21% of the control group were found to have skin disorders. Most were complaints that are commonly encountered in general medical practice. There was a striking absence of skin infestations. The historical consultation rate for skin disorders had not increased. It was concluded that an outbreak of skin disease had not occurred in British troops guarding the dam. This epidemiological study shows that, even under conditions of modern field hygiene, up to one in five soldiers will have skin disease. Skin infestations, however, have become progressively less common during military campaigns this century, probably because of better personal hygiene, good preventive medicine practices and better access to effective health care.

School recess provides an important opportunity for children to engage in physical activity. Previous studies indicate that children and adults of South Asian origin are less active than other ethnic groups in the United Kingdom, but have not investigated whether activity differs within the shared school environment. The aim of this study was to test the hypothesis that British Pakistani girls aged 9-11 years are less active during recess than White British girls. In Study One, the proportion of recess spent by 137 White British (N = 70) and British Pakistani (N = 67) girls in sedentary behavior, moderate-to-vigorous activity (MVPA) and vigorous activity (VPA) was determined using accelerometry. In Study Two, 86 White British (N = 48) and British Pakistani (N = 38) girls were observed on the playground using the System for Observing Children's Activity and Relationships during Play (SOCARP). Accelerometry data were collected during observations to allow identification of activities contributing to objectively measured physical activity. Accelerometry data indicated that British Pakistani girls spent 2.2% (95% CI: 0.2, 4.3) less of their total recess time in MVPA and 1.3% (95% CI: 0.2, 2.4) less in VPA than White British girls. Direct observation showed that British Pakistani girls spent 12.0% (95% CI: 2.9, 21.1) less playground time being very active, and 12.3% (95% CI: 1.7, 23.0) less time playing games. Time spent being very active according to direct observation data correlated significantly with accelerometer-assessed time spent in MVPA and VPA, and time spent playing games correlated significantly with accelerometer-assessed time spent in VPA, suggesting that differences in behavior observed in Study Two may have contributed to the differences in time spent in MVPA and VPA in Study One. British Pakistani girls were less active than White British girls during school recess. Recess has been identified as a potentially important target for the delivery of

The under-representation of minority ethnic groups in UK medical research.

Smart, Andrew; Harrison, Eric

2017-02-01

Objectives . The paper investigates differences in engagement with medical research between White British and Black, Asian and Minority Ethnic (BAME) groups in the UK, using data from the Wellcome Trust Monitor (WTM). The study used two waves of the WTM (n = 2575) to examine associations between ethnic group and participation in medical research, and willingness to participate (WP) in medical research. Logistic regression models controlled for socio-economic and demographic factors, and relevant outlooks and experiences that are assumed to be markers of engagement. Respondents from the BAME group were less likely to have participated in medical research compared to those from the White British group, but there was only patchy evidence of small ethnic group differences in WP. Influences on engagement with medical research varied somewhat between the White British and BAME groups, in particular in relation to occupation, education, health, attitudes to medical science and belief. These findings consolidate previously context-specific evidence of BAME group under-representation in the UK, and highlight heterogeneity in that group. Efforts to address the under-representation of those from BAME groups might benefit from targeted strategies for recruitment and advocacy, although improved data sets are required to fully understand ethnic differences in engagement with medical research.

Weathering the empire: meteorological research in the early British Straits Settlements.

PubMed

Williamson, Fiona

2015-09-01

This article explores meteorological interest and experimentation in the early history of the Straits Settlements. It centres on the establishment of an observatory in 1840s Singapore and examines the channels that linked the observatory to a global community of scientists, colonial officers and a reading public. It will argue that, although the value of overseas meteorological investigation was recognized by the British government, investment was piecemeal and progress in the field often relied on the commitment and enthusiasm of individuals. In the Straits Settlements, as elsewhere, these individuals were drawn from military or medical backgrounds, rather than trained as dedicated scientists. Despite this, meteorology was increasingly recognized as of fundamental importance to imperial interests. Thus this article connects meteorology with the history of science and empire more fully and examines how research undertaken in British dependencies is revealing of the operation of transnational networks in the exchange of scientific knowledge.

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).

OBJECTIVES--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). RESULTS--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. CONCLUSION--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).

Nunes, Everardo Duarte

2011-03-01

Margot Jefferys (1916-1999) was not only the person who introduced medical sociology into Great Britain, but also the researcher and professor who, during thirty years, exerted the most deep influence on the teaching of health social sciences either in undergraduate or especially graduate studies, since the beginning of her career, in 1953, at the London School of Hygiene and Tropical Medicine. In addition to create a global panorama concerning the Jefferys' works, this study highlights two texts, which are situated into the field we are researching: the history of health sociology. The first one, published in 1991, discusses the relationships between epidemiology and sociology; and the second, published in 1996, discusses the field of medical sociology. Both texts are a series of considerations regarding the Jefferys' thought and the more recent questions of the field in Great Britain.

The management of primary hypothyroidism with levothyroxine (L-T4) is simple, effective and safe, and most patients report improved well-being on initiation of treatment. However, a proportion of individuals continue to suffer with symptoms despite achieving adequate biochemical correction. The management of such individuals has been the subject of controversy and of considerable public interest. The American Thyroid Association (ATA) and the European Thyroid Association (ETA) have recently published guidelines on the diagnosis and management of hypothyroidism. These guidelines have been based on extensive reviews of the medical literature and include sections on the role of combination therapy with L-T4 and liothyronine (L-T3) in individuals who are persistently dissatisfied with L-T4 therapy. This position statement by the British Thyroid Association (BTA) summarises the key points in these guidelines and makes recommendations on the management of primary hypothyroidism based on the current literature, review of the published positions of the ETA and ATA, and in line with best principles of good medical practice. The statement is endorsed by the Association of Clinical Biochemistry, (ACB), British Thyroid Foundation, (BTF), Royal College of Physicians (RCP) and Society for Endocrinology (SFE). © 2015 John Wiley & Sons Ltd.

Differences between 9–11 year old British Pakistani and White British girls in physical activity and behavior during school recess

PubMed Central

2012-01-01

Background School recess provides an important opportunity for children to engage in physical activity. Previous studies indicate that children and adults of South Asian origin are less active than other ethnic groups in the United Kingdom, but have not investigated whether activity differs within the shared school environment. The aim of this study was to test the hypothesis that British Pakistani girls aged 9–11 years are less active during recess than White British girls. Methods In Study One, the proportion of recess spent by 137 White British (N = 70) and British Pakistani (N = 67) girls in sedentary behavior, moderate-to-vigorous activity (MVPA) and vigorous activity (VPA) was determined using accelerometry. In Study Two, 86 White British (N = 48) and British Pakistani (N = 38) girls were observed on the playground using the System for Observing Children’s Activity and Relationships during Play (SOCARP). Accelerometry data were collected during observations to allow identification of activities contributing to objectively measured physical activity. Results Accelerometry data indicated that British Pakistani girls spent 2.2% (95% CI: 0.2, 4.3) less of their total recess time in MVPA and 1.3% (95% CI: 0.2, 2.4) less in VPA than White British girls. Direct observation showed that British Pakistani girls spent 12.0% (95% CI: 2.9, 21.1) less playground time being very active, and 12.3% (95% CI: 1.7, 23.0) less time playing games. Time spent being very active according to direct observation data correlated significantly with accelerometer-assessed time spent in MVPA and VPA, and time spent playing games correlated significantly with accelerometer-assessed time spent in VPA, suggesting that differences in behavior observed in Study Two may have contributed to the differences in time spent in MVPA and VPA in Study One. Conclusions British Pakistani girls were less active than White British girls during school recess. Recess has been identified as

Why British GPs use computers and hospital doctors do not.

2001-01-01

Almost all general medical practitioners (GPs) in the UK use computers, compared with less than one in ten of hospital doctors. This paper explains how this unexpected situation came about over a thirty-year period, identifying some of the successes and failures of British medical computing along the way. Twelve separate factors are considered. The major determinants have not been technical, but rather a strong tide of political backing for general practice and leadership from the profession at the highest level, which have combined to build an appropriate regulatory framework and financial incentives that have encouraged GPs to embrace computers. Hospital computing has some difficulties not met by GPs, but the main factor preventing progress has been the lack of any real incentive positive (carrot) or negative (stick), for hospital doctors to use computers.

Diabetes is disproportionately high among British South Asians compared to the general UK population. Whilst the migrant British South Asians group has received most attention on research related to diabetes management, little consideration has been given to impact of travel back to the East. This study aimed to explore the role of social networks and beliefs about diabetes in British South Asians, to better understand their management behaviours whilst holidaying in the East. Semistructured interviews were conducted in Greater Manchester. Forty-four participants were recruited using random and purposive sampling techniques. Interviews were analysed thematically using a constant comparison approach. Migrant British South Asians expressed a strong preference to be in a hot climate; they felt they had a healthier lifestyle in the East and often altered or abandoned their diabetes medication. Information acquisition on diabetes and availability of social networks in the East was valued. Social networks in the East are a valued source of information and support for diabetes. The lack of adherence to medication whilst abroad suggests that some migrant British South Asians have a poor understanding of diabetes. Future research needs to explore whether patients are seeking professional advice on diabetes management prior to their extended holiday.

Effect of bit wear on hammer drill handle vibration and productivity.

The use of large electric hammer drills exposes construction workers to high levels of hand vibration that may lead to hand-arm vibration syndrome and other musculoskeletal disorders. The aim of this laboratory study was to investigate the effect of bit wear on drill handle vibration and drilling productivity (e.g., drilling time per hole). A laboratory test bench system was used with an 8.3 kg electric hammer drill and 1.9 cm concrete bit (a typical drill and bit used in commercial construction). The system automatically advanced the active drill into aged concrete block under feed force control to a depth of 7.6 cm while handle vibration was measured according to ISO standards (ISO 5349 and 28927). Bits were worn to 4 levels by consecutive hole drilling to 4 cumulative drilling depths: 0, 1,900, 5,700, and 7,600 cm. Z-axis handle vibration increased significantly (p<0.05) from 4.8 to 5.1 m/s 2 (ISO weighted) and from 42.7-47.6 m/s 2 (unweighted) when comparing a new bit to a bit worn to 1,900 cm of cumulative drilling depth. Handle vibration did not increase further with bits worn more than 1900 cm of cumulative drilling depth. Neither x- nor y-axis handle vibration was effected by bit wear. The time to drill a hole increased by 58% for the bit with 5,700 cm of cumulative drilling depth compared to a new bit. Bit wear led to a small but significant increase in both ISO weighted and unweighted z-axis handle vibration. Perhaps more important, bit wear had a large effect on productivity. The effect on productivity will influence a worker's allowable daily drilling time if exposure to drill handle vibration is near the ACGIH Threshold Limit Value. [1] Construction contractors should implement a bit replacement program based on these findings.

Enlargement of basilar artery aneurysms following balloon occlusion--"water-hammer effect". Report of two cases.

Two patients with distal basilar aneurysms were treated with intra-aneurysmal balloon occlusion. After apparently successful therapy, follow-up angiograms demonstrated aneurysm enlargement with balloon migration distally in the sac. Geometric mismatch between the base of the balloons and the aneurysm neck together with transmitted pulsation through the 2-hydroxyl-ethylmethacrylate (HEMA)-filled balloon directly contributed to aneurysm enlargement. In this report, the authors discuss the problems of progressive aneurysm enlargement due to a "water-hammer effect" and the possibility of hemorrhage following subtotal occlusion.

(Re-)reading medical trade catalogs: the uses of professional advertising in British medical practice, 1870-1914.

PubMed

Jones, Claire L

2012-01-01

This article explores how medical practitioners read, used, and experienced medical trade catalogs in late-nineteenth- and early-twentieth-century Britain. Reader responses to the catalog, a book-like publication promoting medical tools, appliances, and pharmaceuticals, have been chronically understudied, as have professional reading practices within medicine more generally. Yet, evidence suggests that clinicians frequently used the catalog and did so in three main ways: to order medical products, to acquire new information about these products, and to display their own product endorsements and product designs. The seemingly widespread nature of these practices demonstrates an individual and collective professional desire to improve medical practice and highlights the importance of studying professional reading practices in the cultural history of medicine.

Energy based simulation of a Timoshenko beam in non-forced rotation. Influence of the piano hammer shank flexibility on the sound

NASA Astrophysics Data System (ADS)

Chabassier, Juliette; Duruflé, Marc

2014-12-01

A nonlinear model for a vibrating Timoshenko beam in non-forced unknown rotation is derived from the virtual work principle applied to a system of beam with mass at the end. The system represents a piano hammer shank coupled to a hammer head. An energy-based numerical scheme is then provided, obtained by non-classical approaches. A major difficulty for time discretization comes from the nonlinear behavior of the kinetic energy of the system. This new numerical scheme is then coupled to a global energy-preserving numerical solution for the whole piano. The obtained numerical simulations show that the pianistic touch clearly influences the spectrum of the piano sound of equally loud isolated notes. These differences do not come from a possible shock excitation on the structure, or from a changing impact point, or a “longitudinal rubbing motion” on the string, since neither of these features is modeled in our study.

Explosion-source phenomenology is best studied when competing signals (such as instrument, site, and propagation effects), are well understood. The second phase of the Source Physics Experiments (SPE), is moving from granite geology to alluvium geology at Yucca Flat, Nevada National Security Site. To improve subsurface characterization of Yucca Flat (and therefore better understand propagation and site effects), an active-source seismic survey was conducted using a novel 13,000-kg impulsive hammer source. The source points, spaced 200 m apart, covered a N-S transect spanning 18 km. Three component, 2-Hz geophones were used to record useable signals out to 10 km. We inverted for P-wave velocity by computing travel times using a finite-difference 3D eikonal solver, and then compared that to the picked travel times using a linearized iterative inversion scheme. Preliminary results from traditional reflection processing methods are also presented.

Though the Nuremberg medical trial was a United States military tribunal, British forensic pathologists supplied extensive evidence for the trial. The BMJ had a correspondent at the trial, and he endorsed a utilitarian legitimation of clinical experiments, justifying the medical research carried out under Nazism as of long term scientific benefit despite the human costs. The British supported an international medical commission to evaluate the ethics and scientific quality of German research. Medical opinions differed over whether German medical atrocities should be given publicity or treated in confidence. The BMJ's correspondent warned against medical researchers being taken over by a totalitarian state, and these arguments were used to oppose the NHS and any state control over medical research.

Hypothenar hammer syndrome in sports.

1996-01-01

Repetitive blunt trauma or single severe trauma to the hypothenar region may lead to traumatic thrombosis of the distal ulnar artery (hypothenar hammer syndrome, HHS). In the sports-related literature we found and analysed isolated cases attributed to injuries sustained during sporting activities such as baseball, badminton, handball, football, frisbee, softball, karate, weight-lifting and hockey. Further, we report the case of an amateur golf player with ischaemic symptoms of his left hand, where angiography revealed filling defects in the digital arteries associated with a corkscrew-like configuration of the distal ulnar artery. Magnetic resonance imaging (MRI) scan demonstrated, at the level of the hamulus ossis hamati, accessory fibres of m. palmaris brevis forming a sling around the ulnar artery. Treatment by resection of the thrombosed a. ulnaris segment and replacement with an autologous vein graft resulted in complete relief of symptoms. Histological sections revealed partially organized thrombi adherent to the intimal surface with fragmentation of the internal elastic membrane, indicating a traumatic genesis. As the mechanism of injury, we suspected intensive golf playing with the grip style and subsequent motions leading to pressure injury of the hypothenar area and the underlying ulnar artery. Contraction of the anomalous muscle belly may have additionally compressed the artery, slowing down the arterial flow and promoting thrombosis. In most reported cases including our own, it took a relatively long time until the cause of the disease as traumatic was found and accepted. The initial repetitive blunt or single severe trauma initiating the HHS can easily be overlooked or ignored. After intimal damage of a. ulnaris, the beginning of symptoms may be prolonged and mislead one into thinking the cause is a collagen or vasospastic disease.

Medical humanities: some uses and problems.

Downie, R

2016-12-01

The arts and humanities were allowed into the British medical curriculum in 1993 when the General Medical Council re-structured it in a paper entitled 'Tomorrow's Doctors'. Since then many medical schools have developed humanities modules and the broad term 'medical humanities' refers to these. They can contribute to medical education in at least three ways: as a supplement to what is already in the curriculum, especially for ethics and communication; as an outside critique of medical practice; and to personal and professional development. Nevertheless, there are practical problems concerning appropriate teachers and methods of assessment. Moreover, the dominant interest is now academic research rather than education.

Job satisfaction among British and American hospital staff nurses.

1991-01-01

The basic research design was descriptive, correlational, and non-experimental. Sampling was nonprobability; a convenience sample was obtained after subjects gave informed consent. A Likert-type attitude scale was used to collect data on job satisfaction. The population was full-time hospital staff nurses and a total sample of 146 participated in the project. The settings were four hospitals, two in the north of England and two in the midwest United States. The British study was done three years after the American. Data were collected by questionnaire, which was distributed by hand and collected personally. Results revealed British nurses were very dissatisfied with pay. If it were not for the pay component, the British nurses would have scored significantly higher than Americans on overall satisfaction. American nurses perceived greater satisfaction with their nursing colleagues than the British but were less satisfied with administration. However, British nurses perceived a more cooperative relationship with physicians. British nurses, despite their complete dissatisfaction with pay, would overwhelmingly choose nursing again.

British cognitive developmental psychology is characterized by its interest in philosophical questions, its preference for linking basic research to applied issues in education and cognitive disorders, and its willingness to learn both methodologically and theoretically from work in animal psychology and in physiology more generally. It has also been influenced profoundly by Jean Piaget's cognitive stage theory although in general British work has focused on demonstrating early strengths, rather than early deficits, in infant and child cognition. Following an overview of British work that encompasses past and present interests, issues and challenges for the future are highlighted. While the perspectives of the founding members of the British Psychological Society (BPS), as outlined by Edgell (1947), are still apparent in British research in cognitive developmental psychology today, it is argued that future cognitive work must become even more interdisciplinary and that the symbiotic relationship between research in adult cognition and in cognitive development needs greater recognition.

The long term effects of encapsulation individual sheets of the Codex Hammer were investigated. The manuscript was simulated with similar sheets of paper which were photographed under repeatable raking light conditions to enhance their surface texture, encapsulated in plexiglas, cycled in an environmental test chamber, and rephotographed at selected intervals. The film images were digitized, contrast enhanced, geometrically registered, and apodized. An FFT analysis of a control sheet and two experimental sheets indicates no micro-burnishing, but reveals that the ""mesoscale'' deformations with sizes 8mm are degrading monotonically, which is of no concern. Difference image analysis indicates that the sheets were increasingly stressed with time and that the plexiglas did not provide a sufficient environmental barrier under the simulation conditions. The relationship of these results to the Codex itself is to be determined.

Medical students' perceptions in relation to ethnicity and gender: a qualitative study.

The British medical student population has undergone rapid diversification over the last decades. This study focuses on medical students' views about their experiences in relation to ethnicity and gender during their undergraduate training within the context of the hidden curriculum in one British medical school as part of a wider qualitative research project into undergraduate medical education. We interviewed 36 undergraduate medical students in one British Medical School, across all five years of training using a semi-structured interview schedule. We selected them by random and quota sampling, stratified by sex and ethnicity and used the whole medical school population as a sampling frame. Data analyses involved the identification of common themes, reported by means of illustrative quotations and simple counts. The students provided information about variations patterned by gender in their motivation and influences when deciding to study medicine. Issues in relation to ethnicity were: gaining independence from parents, perceived limitations to career prospects, incompatibility of some religious beliefs with some medical practices and acquired open-mindedness towards students and patients from different ethnic backgrounds. Despite claiming no experiences of gender difference during medical training, female and male students expressed gender stereotypes, e.g. that women bring particularly caring and sympathetic attitudes to medicine, or that surgery requires the physical strength and competitiveness stereotypically associated with men that are likely to support the continuation of gender differentiation in medical careers. The key themes identified in this paper in relation to ethnicity and to gender have important implications for medical educators and for those concerned with professional development. The results suggest a need to open up aspects of these relatively covert elements of student culture to scrutiny and debate and to take an explicitly wider view

As medicine moves into the 21st century, life saving therapies will move from inception into medical products faster if there is a better synergy between science and business. Medicine appears to have 50-year innovative cycles of education and scientific discoveries. In the 1880’s, the chemical industry in Germany was faced with the dilemma of modernization to exploit the new scientific discoveries. The solution was the spawning of novel technical colleges for training in these new chemical industries. The impact of those new employees and their groundbreaking compounds had a profound influence on medicine and medical education in Germany between 1880 and 1930. Germany dominated international science during this period and was a training center for scientists worldwide. This model of synergy between education and business was envied and admired in Europe, Asia and America. British science soon after evolved to dominate the field of science during the prewar and post World War (1930’s–1970’s) because the German scientists fled Hitler’s government. These expatriated scientists had a profound influence on the teaching and training of British scientists, which lead to advances in medicine such as antibiotics. After the Second World War, the US government wisely funded the development of the medical infrastructure that we see today. British and German scientists in medicine moved to America because of this bountiful funding for their research. These expatriated scientists helped drive these medical advances into commercialized products by the 1980’s. America has been the center of medical education and advances of biotechnology but will it continue? International scientists trained in America have started to return to Europe and Asia.

Dr Percy Charles Edward d'Erf Wheeler, a medical missionary of the London Society for Promoting Christianity Amongst the Jews, spent 24 years (1885-1909) as head of the English medical institution in Jerusalem. Wheeler dedicated the years he served in Palestine to promote the medical condition of the Jews as a means of missionary work. The most significant of his achievements was his leading role in the founding of the new British Hospital for the Jews in Jerusalem, the flagship of the British presence in Palestine, to be inaugurated in 1897.

A brief history of British military experiences with infectious and tropical diseases.

PubMed

Bailey, Mark S

2013-09-01

Infectious and tropical diseases have been a problem for British expeditionary forces ever since the Crusades. Outbreaks were especially common on Navy ships from the 16th to 18th centuries due to poor living conditions and travel to the tropics. However, since these occurred in small, isolated and controlled environments it meant that naval medical practitioners were able to keep detailed records and develop empirical approaches for their prevention. The first Royal Naval Hospitals were established in response to these diseases and Royal Navy doctors made valuable early contributions towards understanding them. Even larger outbreaks of infectious and tropical diseases occurred in the Army during the Napoleonic, Crimean and Boer Wars and throughout the colonial era, which strongly influenced the formation of the Army Medical Services including provision for teaching and research. The establishment of germ theory led to a golden era of discovery regarding these diseases and British Army doctors made numerous important contributions. Subsequent improvements in prevention, diagnosis and treatment reduced the mortality from infectious and tropical diseases during the World Wars, but they remained a significant problem in the non-European campaigns and also the numerous 'small wars' that followed. Even in the 21st century some of these diseases still cause outbreaks with significant morbidity and impact on deployments, but the military clinical and academic resources to deal with them are now much reduced. Preventive measures such as hygiene, sanitation, infection control, vaccination and chemoprophylaxis are invaluable, but history shows that these can become neglected over time and disrupted or overwhelmed during the early or most intense stages of military operations. This is why military specialists in infectious diseases, tropical medicine, sexual health, medical microbiology and communicable diseases control are still required.

Reliability of the Achilles tendon tap reflex evoked during stance using a pendulum hammer.

PubMed

Mildren, Robyn L; Zaback, Martin; Adkin, Allan L; Frank, James S; Bent, Leah R

2016-01-01

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.

[Private charity - public health service. Comparison between British and German birthing centers of the 18th century].

PubMed

Schlumbohm, Jürgen

In the eighteenth century, lying-in hospitals were founded in many European towns and cities. The way in which these institutions were financed differed greatly across Europe. In the UK, most of them were "charities" and relied on donations from wealthy benefactors, whereas on the continent they were usually funded by "public" money, be it from the state or local communities. The paper focuses on British charities and German hospitals, and explores the corollaries of the mode of financing. In the eighteenth century, a market emerged in Britain where numerous charities with different aims competed for donations from the well-to-do. For attracting benefactors, a charity had to convince potential donors that its clientele and purpose were particularly deserving, and that it used the money donated in a cost-efficient way. In Germany, it was mainly bureaucrats and governments who had to be persuaded, but public opinion did matter as well. In British lying-in charities, the main donors acted as governors, and benefactors could recommend persons for being admitted. In publicly funded German hospitals, the medical directors had much more power. In the competitive market, in which British charities acted, out-patient dispensaries (policlinics) became increasingly important, since they could argue that they were more cost-efficient and had lower mortality. In Germany, however, hospitals remained the dominant type of assistance in this field, in spite of the criticism they received. The different sources of finance appear to have been one of the reasons for this divergence. Teaching was the main purpose of most German lying-in hospitals. They either trained medical students or midwife apprentices or both. Since the patients served as teaching objects, all women were welcomed, and in fact most patients were single mothers. By contrast, most of the British institutions admitted only married women, because donors did not wish to encourage immorality. The charities staged the

Medical practice in New Zealand 1769-1860.

PubMed

Lawrenson, Ross

2004-06-01

New Zealand was discovered by Captain Cook in 1769. Over the next ninety years, increasing numbers of medical practitioners visited and began to settle in what became a British colony. The first medical visitors were usually naval surgeons or served on board whaling ships. The major influx of doctors occurred at the behest of the New Zealand Company between 1840 and 1848, although Christian missionaries, army doctors, and individual medical entrepreneurs also emigrated and provided services. This paper describes the pattern of medical settlement in the colony's earliest years and relates this to the health of the population and the development of medical and hospital services.

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

Winkler, Stefan; Lambiel, Christophe; Sattler, Katrin; Büche, Thomas; Springer, Johanna

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

Background/Aim Why has the apparently high rate of cousin marriage among Bradford Pakistanis been sustained, 50 years since Pakistani migration to Britain began? Methods A review of the anthropological literature on Pakistani migration and settlement, British Pakistani marriage patterns and the phenomenon of transnational marriage. Results British Pakistanis are diverse in regional origins and social class characteristics, with many Bradford Pakistanis originating from the Mirpur district and northern Punjab. British Pakistani marriages often involve a partner from Pakistan who joins a spouse in the UK. Transnational marriage of first cousins offers relatives in Pakistan opportunities for a ‘better’ life in the West and are important for British Pakistanis for economic, social, cultural and emotional reasons. These processes are also differentially influenced by region of origin and class characteristics in Pakistan as well as by education, employment and locality in Britain. The pattern observed in Bradford may not be applicable nationally. Conclusion Further research examining marital decisions over several generations in families differing by social class, region of origin in Pakistan and locality in Britain is necessary to contextualise the findings from Bradford.

2006-01-01

Background The British medical student population has undergone rapid diversification over the last decades. This study focuses on medical students' views about their experiences in relation to ethnicity and gender during their undergraduate training within the context of the hidden curriculum in one British medical school as part of a wider qualitative research project into undergraduate medical education. Method We interviewed 36 undergraduate medical students in one British Medical School, across all five years of training using a semi-structured interview schedule. We selected them by random and quota sampling, stratified by sex and ethnicity and used the whole medical school population as a sampling frame. Data analyses involved the identification of common themes, reported by means of illustrative quotations and simple counts. Results The students provided information about variations patterned by gender in their motivation and influences when deciding to study medicine. Issues in relation to ethnicity were: gaining independence from parents, perceived limitations to career prospects, incompatibility of some religious beliefs with some medical practices and acquired open-mindedness towards students and patients from different ethnic backgrounds. Despite claiming no experiences of gender difference during medical training, female and male students expressed gender stereotypes, e.g. that women bring particularly caring and sympathetic attitudes to medicine, or that surgery requires the physical strength and competitiveness stereotypically associated with men that are likely to support the continuation of gender differentiation in medical careers. Conclusion The key themes identified in this paper in relation to ethnicity and to gender have important implications for medical educators and for those concerned with professional development. The results suggest a need to open up aspects of these relatively covert elements of student culture to scrutiny and debate

Color management with a hammer: the B-spline fitter

NASA Astrophysics Data System (ADS)

Bell, Ian E.; Liu, Bonny H. P.

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.

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.

A study was made of recruit medical discharges in the British Army in 1988 with the aim of ascertaining the number of medical discharges amongst recruits. AFBs 6863 (Notification of Discharge of a Regular Recruit) were used as the source of data. Recruit medical wastage rate for 1988 was 897 cases, or 16.7% of all known discharges. Three types of medical discharges were present. Four hundred and ninety-six Type 1 or concealed discharges, (9.2% of discharges for all reasons) were made up of cases who had not been boarded and had mainly been discharged under QR 9.381 (defect of enlistment). Two hundred and seventy-five Type 2 discharges (5.1% of discharges for all reasons) represented boarded cases discharged under QR 9.385 (ceasing to fulfil medical requirements). One hundred and twenty-six Type 3 discharges (2.3% of all discharges) were boarded cases mainly discharged under QR 9.381 (defect of enlistment). As all discharges under paragraphs other than QR 9.385 are given administrative discharge outflow code, only the 275 Type 2 discharges (or 31.7% of medical discharges) appeared on the Army's own source of medical data, the TRIMEDS database. This had the effect of concealing the majority of those discharges caused by conditions predating enlistment therefore decreasing the number of known false negatives not detected at recruiting medicals. The biggest causes of discharge were conditions of the lower limbs and back (54.5% of medical discharges), a conglomerate of minor categories of pathology (14.6%), asthma (9.6%) and deformities (7.4%). Within each type the bulk of the discharges was concealed in Type 1 discharges especially for conditions predating enlistment.(ABSTRACT TRUNCATED AT 250 WORDS)

Purpose. Surgical procedures are likely to be stressful for patients and their families. Total knee arthroplasty (TKA) is a major surgical procedure used in the treatment of osteoarthritis. During this procedure the sounds of the saw and hammer may irritate the patient and adversely affect mood. The present study examines the effect of these intraoperative sounds during TKA on postoperative mood and anxiety, by comparing two different anesthetic procedures. Methods. A total of 40 patients who underwent TKA for grade IV gonarthrosis participated in the study. Patients were randomly divided into two groups: 20 patients in the general anesthesia group and 20 patients in the spinal anesthesia group. Mood and anxiety changes were evaluated using the Profile of Mood States (POMS) and State-Trait Anxiety Inventory (STAI) instruments, respectively. Results. The postoperative POMS value in the spinal anesthesia group was definitively higher than the general anesthesia group, though the difference in preoperative and postoperative POMS and STAI scores between the two groups was not significant. Conclusion. It would seem that sounds of hammer and saw have no evident negative effect on patient's mood. Regional anesthesia is advisable for TKA patients and appropriate sedation can be administered during the operation if needed. PMID:25793222

2018-05-01

Introduction Venous thromboembolism (VTE) remains a major public health issue around the world. Ethnicity is known to alter the incidence of VTE. To our knowledge, there are no reports in the literature investigating the incidence of VTE in British Indians. The aim of this study was to investigate the rates of symptomatic VTE in British Indian patients in the UK. Methods Patients referred to our institution between January 2011 and August 2013 with clinically suspected VTE were eligible for inclusion in the study. Those not of British Indian or Caucasian ethnicity were excluded. A retrospective review of these two cohorts was conducted. Results Overall, 15,529 cases were referred to our institution for suspected VTE. This included 1,498 individuals of British Indian ethnicity. Of these, 182 (12%) had confirmed VTE episodes. A further 13,159 of the patients with suspected VTE were coded as Caucasian, including 2,412 (16%) who had confirmed VTE events. VTE rates were a third lower in British Indians with clinically suspected VTE than in the equivalent Caucasian group. The British Indian cohort presented with VTE at a much earlier age than Caucasians (mean 57.0 vs 68.0 years). Conclusions This study suggests that British Indian patients have a lower incidence of VTE and are more likely to present at an earlier age than Caucasians. There was no significant difference in VTE type (deep vein thrombosis vs pulmonary embolism) among the ethnic groups. Clinicians should be aware of variations within ethnicities but should continue to adhere to existing VTE prevention guidance.

This letter is a response to a recent report by J. S. Yaruss, C. Coleman, and D. Hammer (2006) that described a treatment program for preschool children who stutter. Problems with the Yaruss et al. study fall into four domains: (a) failure to provide clinicians with replicable procedures, (b) failure to collect valid and reliable speech performance data, (c) failure to control for predictable improvement in children who have been stuttering for less than 15 months, and (d) the advocacy of procedures for which there is no credible research evidence. The claims made for the efficacy of this treatment are problematic and essentially violate the principles of evidence-based practice as recommended by the American Speech-Language-Hearing Association (ASHA).

Ross, which rely on several principles that potentially could conflict. He summarizes the contributions of Kant and Ross to the development of deontological thought, then concludes his essay with brief paragraphs on other deontological approaches to the resolution of conflicting moral principles.

2012-01-01

Taiwan's medical education system bears a close relationship with its colonial and post-colonial history. Since the late nineteenth century, Western medicine, Chinese medicine, and the practice of the other forms of traditional healing have encountered complex transactions with the state and one another, eventually evolving into the present medical system. Nowadays, the mainstream form of medical education in Taiwan is a 7-year Western program; other forms of medical education include a 5-year graduate program and traditional medicine programs. Challenged by the National Health Insurance that emphasizes cost management since 1995 and criticized by the US National Committee on Foreign Medical Education and Accreditation in 1998, medical education reform was implemented by the Taiwan Medical Accreditation Council established in 2000. The reform tries to bring humanities into various aspects of medical education, including student recruitment, curriculum, licensing, and continuing education. Similar to other modernization projects, the reform transplants the American and British standards to Taiwan. These changes hope to insure the reflective capabilities in physicians on the welfare of patients. However, frustration of current and future physicians may be deepened if the reform is insensitive to local issues or incapable of addressing new global tendencies.

Ethics surrounding the medical evacuation of catastrophically injured individuals from an operational theatre of war.

PubMed

Bennett, Rebecca A

2016-10-01

Although prolonging life is usually in the best interests of patients, the British Medical Association states that it is not appropriate to prolong life with no regard to its quality. Medical advances both on the battlefield and within the field hospitals have resulted in the unexpected survival of a number of British personnel, and in some cases, soldiers are being repatriated with injuries categorised as 'catastrophic'. This paper considers medical ethics based on the Beauchamp and Childress Four Principles framework with regard to whether catastrophically injured individuals should be repatriated without any prior advanced directive and without evaluation of future quality of life.

Schmidt-hammer exposure-age dating (SHD) of Lateglacial rock glacier systems near the eastern margin of the European Alps

NASA Astrophysics Data System (ADS)

Kellerer-Pirklbauer, Andreas

2016-04-01

Rock glaciers are widespread permafrost landforms in Austria. Various rock glacier inventories list more than 4500 rock glaciers in the country; some 30-40% of them are intact. Relict (permafrost free) and pseudo-relict rock glaciers (sporadic and isolated permafrost particularly near the root zone) prevail in number. Rock glaciers are commonly formed over a period of several ka. Dating such landforms helps to understand palaeoclimatic conditions. In this study three rock glaciers consisting of gneiss were dated applying the Schmidt-hammer exposure-age dating (SHD) method. The rock glaciers are located at three neighbouring cirques in the Seckauer Tauern Range named Reichart Rock Glacier (RRG, area 1.26 km², length 1800 m, elevation range 1520-1940 m a.s.l.), Schöneben Rock Glacier (SRG, 0.11 km², 750 m, 1715-1905 m a.s.l.), and Dürrtal Rock Glacier (DRG, 0.08 km², 850 m, 1750-1980 m a.s.l.). RRG is one of the largest rock glaciers in Austria. All three landforms are influenced by lenses of permafrost at present (as indicated by ERT). During the LGM the Seckauer Tauern were covered by valley glaciers and deglaciation occurred presumably already early in the Alpine Lateglacial period. An analogue N-type Schmidt-hammer (proceq) was used for measuring the surface strength of stable blocks at the rock glacier surface by recording a rebound value (R-value) of a spring-loaded bolt. The R-value gives a relative measure of the surface hardness and hence time since exposure to weathering. Eight (RRG) or six (SRG, DRG) Schmidt-hammer measurement sites (with 50-100 individual readings) aligned along longitudinal transects (=former central flow line) between a talus slope (with relatively fresh boulders) in the root zone and the frontal ridge were measured. Mean R-value differences of 30.5 at RRG, 25.1 at SRG, and 20.7 at DRG were revealed along the three transects. The differences between the lowest and the highest R-value at the rock glaciers itself were 19.0 at RRG, 15

The women of the family? Speculations around early modern British physicians.

PubMed

Pelling, M

1995-12-01

In the extensively explored areas of professionalization, domestic ideology, and the relationships between women and medicine, the debate on the British case has given little consideration to issues of identity arising for the male medical practitioner as a result of family life. For the early modern period, these issues can be seen as among a broad-ranging set of problems posed by the female gender connotations of the medical role. Such problems were most pronounced for the élite physicians who sought membership of the London College of Physicians. Their attitudes and dilemmas are important because of their influence, over the long term, on the criteria for professionalization. Using biographical data, a contrast can be shown between the dynastic ideals of physicians, which stressed the male line, and the high incidence among such physicians of celibacy, childlessness, and small families. Families of origin of physicians, on the other hand, tended to be large. Assumptions about the role of women in medical care, especially in clerical and gentry families, entail a recognition of the possible influence of female relatives on the vocations of male physicians. Given the low status of women's work, physicians developed ambivalences which affected the construction of their identities, their families, and the passing on of their skills.

Fluid-structure interaction with pipe-wall viscoelasticity during water hammer

NASA Astrophysics Data System (ADS)

Keramat, A.; Tijsseling, A. S.; Hou, Q.; Ahmadi, A.

2012-01-01

Fluid-structure interaction (FSI) due to water hammer in a pipeline which has viscoelastic wall behaviour is studied. Appropriate governing equations are derived and numerically solved. In the numerical implementation of the hydraulic and structural equations, viscoelasticity is incorporated using the Kelvin-Voigt mechanical model. The equations are solved by two different approaches, namely the Method of Characteristics-Finite Element Method (MOC-FEM) and full MOC. In both approaches two important effects of FSI in fluid-filled pipes, namely Poisson and junction coupling, are taken into account. The study proposes a more comprehensive model for studying fluid transients in pipelines as compared to previous works, which take into account either FSI or viscoelasticity. To verify the proposed mathematical model and its numerical solutions, the following problems are investigated: axial vibration of a viscoelastic bar subjected to a step uniaxial loading, FSI in an elastic pipe, and hydraulic transients in a pressurised polyethylene pipe without FSI. The results of each case are checked with available exact and experimental results. Then, to study the simultaneous effects of FSI and viscoelasticity, which is the new element of the present research, one problem is solved by the two different numerical approaches. Both numerical methods give the same results, thus confirming the correctness of the solutions.

Screening for cardiac disease in potential recruits to the British Army.

2015-09-01

The British Army screens potential recruits for disease, including cardiovascular disease, at the pre-employment medical assessment in the Army Selection Centres. The epidemiology of cardiovascular disease in the Armed Forces coupled with the high physical demand placed on the cardiovascular system, often in remote locations make screening desirable. This is particularly pertinent as servicemen and women die from cardiovascular disease each year. To evaluate this particular screening system it is essential to understand the aim of the system, how it is designed and how screening systems in general are evaluated. The efficacy of a screening test is quantified using the measurements of sensitivity, specificity and likelihood ratios. These measurements are defined and the pitfalls associated with evaluating a screening system are described. The different screening tests used to identify cardiac disease and their individual strengths and weaknesses, are illustrated. Finally the article reviews the previous British Army recruit cardiac screening system, that used a stereotyped history and physical examination and the newer system that replaced it, which includes the incorporation of the 12-lead ECG and on site echocardiography in individuals revealing abnormalities on history, examination or ECG.

British sociology and public intellectuals: consumer society and imperial decline.

PubMed

Turner, Bryan S

2006-06-01

The following is the lecture given for the BJS 2005 Public Sociology Debate given at the London School of Economics and Political Science on ll October 2005. This lecture on the character of British sociology provides a pretext for a more general inquiry into public intellectual life in postwar Britain. The argument put forward falls into several distinctive sections. First, British social science has depended heavily on the migration of intellectuals, especially Jewish intellectuals who were refugees from fascism. Second, intellectual innovation requires massive, disruptive, violent change. Third, British sociology did nevertheless give rise to a distinctive tradition of social criticism in which one can argue there were (typically home-grown) public intellectuals. The main theme of their social criticism was to consider the constraining and divisive impact of social class, race and gender on the enjoyment of expanding social citizenship. Fourth, postwar British sociology came to be dominated by the analysis of an affluent consumer society. Finally, the main failure of British sociology in this postwar period was the absence of any sustained, macro-sociological analysis of the historical decline of Britain as a world power in the twentieth century.

The British Army is predominately composed of young men, often from disadvantaged backgrounds, in which Depression is a common mental health disorder. To construct a predictive model detailing the presentation of depression in the army that could be utilised as an educational and clinical guideline for Army clinical personnel. Utilising a Constructivist Grounded Theory, phase 1 consisted of 19 interviews with experienced Army mental health clinicians. Phase 2 was a validation exercise conducted with 3 general practitioners. Depression in the Army correlates poorly with civilian definitions, and has a unique interpretation. Young soldiers presented with symptoms not in the International Classification of Disorders and older soldiers who feared being medically downgraded, sought help outside the Army Medical Services. Women found it easier to seek support, but many were inappropriately labelled as depressed. Implications include a need to address the poor understanding of military stressors; their relationships to depressive symptoms and raise higher awareness of gender imbalances with regard to access and treatment. The results have international implications for other Armed forces, and those employed in Young Men's Mental Health. The results are presented as a simple predictive model and aide memoire that can be utilised as an educational and clinical guideline. There is scope to adapt this model to international civilian healthcare practice. Crown Copyright © 2013. Published by Elsevier Ltd. All rights reserved.

Educating physicians in the procedural as well as cognitive skills of information technology (IT)-mediated medication management could be one of the missing links for the improvement of patient safety. We aimed to compose a framework of tasks that need to be addressed to optimize medication management in outpatient care. Formal task analysis: decomposition of a complex task into a set of subtasks. First, we obtained a general description of the medication management process from exploratory interviews. Secondly, we interviewed experts in-depth to further define tasks and subtasks. Outpatient care in different fields of medicine in six teaching and academic medical centres in the Netherlands and the United States. 20 experts. Tasks were divided up into procedural, cognitive and macrocognitive tasks and categorized into the three components of dynamic decision making. The medication management process consists of three components: (i) reviewing the medication situation; (ii) composing a treatment plan; and (iii) accomplishing and communicating a treatment and surveillance plan. Subtasks include multiple cognitive tasks such as composing a list of current medications and evaluating the reliability of sources, and procedural tasks such as documenting current medication. The identified macrocognitive tasks were: planning, integration of IT in workflow, managing uncertainties and responsibilities, and problem detection. All identified procedural, cognitive and macrocognitive skills should be included when designing education for IT-mediated medication management. The resulting framework supports the design of educational interventions to improve IT-mediated medication management in outpatient care. © 2015 The Authors.

Cavitating flow during water hammer using a generalized interface vaporous cavitation model

Sadafi, Mohamadhosein; Riasi, Alireza; Nourbakhsh, Seyed Ahmad

2012-10-01

In a transient flow simulation, column separation may occur when the calculated pressure head decreases to the saturated vapor pressure head in a computational grid. Abrupt valve closure or pump failure can result in a fast transient flow with column separation, potentially causing problems such as pipe failure, hydraulic equipment damage, cavitation or corrosion. This paper reports a numerical study of water hammer with column separation in a simple reservoir-pipeline-valve system and pumping station. The governing equations for two-phase transient flow in pipes are solved based on the method of characteristics (MOC) using a generalized interface vaporous cavitating model (GIVCM). The numerical results were compared with the experimental data for validation purposes, and the comparison indicated that the GIVCM describes the experimental results more accurately than the discrete vapor cavity model (DVCM). In particular, the GIVCM correlated better with the experimental data than the DVCM in terms of timing and pressure magnitude. The effects of geometric and hydraulic parameters on flow behavior in a pumping station with column separation were also investigated in this study.

‘A matter of commonsense’: the Coventry poliomyelitis epidemic 1957 and the British public

Abstract In 1956, the British Ministry of Health instituted a vaccination programme against poliomyelitis, but run into myriad supply and administrative issues. When Coventry experienced an epidemic in 1957, it came to symbolise these problems. Throughout, it was claimed that the government lacked ‘common sense’. This article explores how and why ‘common sense’ was used as a rhetorical weapon in the debates over policy at the local and national level. While those claiming ‘common sense’ were often at odds with medical and administrative authorities, the arguments were often informed by deeply held beliefs about vaccination and disease.

This is a brief exploration of the ethical issues raised for psychiatrists, and for universities, schools and wider society, by the demand that they attend mandatory training as part of the UK government's Prevent counter-terrorism strategy. The silence on this matter to date on the part of the General Medical Council, medical Royal Colleges, and the British Medical Association is a failure of ethical leadership. There is also a civil liberties issue, reminiscent of the McCarthyism of 1950s USA. We should refuse to attend.

Perpetuating stigma? Differences between advertisements for psychiatric and non-psychiatric medication in two professional journals.

2010-02-01

Continuing debates regarding advertising and the pharmaceutical industry, and others detailing the continued stigmatization of mental health problems. To establish whether there are any differences in advertisements for psychiatric and non-psychiatric medication aimed at health professionals. Quantitative (t-tests, Chi-squared) and qualitative analysis of all unique advertisements for medication that appeared in two professional journals (the British Medical Journal and the British Journal of Psychiatry) between October 2005 and September 2006 was undertaken. Close attention was paid to both images and text used in the advertisements. Significant differences were found between advertisements for psychiatric and non-psychiatric medication in both quantitative and qualitative analysis: advertisements for psychiatric medication contain less text and are less likely to include specific information about the actual drug than non-psychiatric medication advertisements; images used in advertisements for psychiatric medication are more negative than those used for non-psychiatric medication, and are less likely to portray people in everyday situations. A distinction between mental health problems and other forms of ill health is clearly being maintained in medication advertisements; this has potentially stigmatizing consequences, both for professional and public perceptions. There are also troubling implications in light of the debates surrounding Direct to Consumer Advertising.

Objectives To examine the feasibility of detecting adverse events through record review in British hospitals and to make preliminary estimates of the incidence and costs of adverse events. Design Retrospective review of 1014 medical and nursing records. Setting Two acute hospitals in Greater London area. Main outcome measure Number of adverse events. Results 110 (10.8%) patients experienced an adverse event, with an overall rate of adverse events of 11.7% when multiple adverse events were included. About half of these events were judged preventable with ordinary standards of care. A third of adverse events led to moderate or greater disability or death. Conclusions These results suggest that adverse events are a serious source of harm to patients and a large drain on NHS resources. Some are major events; others are frequent, minor events that go unnoticed in routine clinical care but together have massive economic consequences. PMID:11230064

Development of size reduction equations for calculating power input for grinding pine wood chips using hammer mill

Naimi, Ladan J.; Collard, Flavien; Bi, Xiaotao

Size reduction is an unavoidable operation for preparing biomass for biofuels and bioproduct conversion. Yet, there is considerable uncertainty in power input requirement and the uniformity of ground biomass. Considerable gains are possible if the required power input for a size reduction ratio is estimated accurately. In this research three well-known mechanistic equations attributed to Rittinger, Kick, and Bond available for predicting energy input for grinding pine wood chips were tested against experimental grinding data. Prior to testing, samples of pine wood chips were conditioned to 11.7% wb, moisture content. The wood chips were successively ground in a hammer millmore » using screen sizes of 25.4 mm, 10 mm, 6.4 mm, and 3.2 mm. The input power and the flow of material into the grinder were recorded continuously. The recorded power input vs. mean particle size showed that the Rittinger equation had the best fit to the experimental data. The ground particle sizes were 4 to 7 times smaller than the size of installed screen. Geometric mean size of particles were calculated using two methods (1) Tyler sieves and using particle size analysis and (2) Sauter mean diameter calculated from the ratio of volume to surface that were estimated from measured length and width. The two mean diameters agreed well, pointing to the fact that either mechanical sieving or particle imaging can be used to characterize particle size. In conclusion, specific energy input to the hammer mill increased from 1.4 kWh t –1 (5.2 J g –1) for large 25.1-mm screen to 25 kWh t –1 (90.4 J g –1) for small 3.2-mm screen.« less

Dynamics of sonoluminescing bubbles within a liquid hammer device.

Urteaga, Raúl; García-Martínez, Pablo Luis; Bonetto, Fabián J

2009-01-01

We studied the dynamics of a single sonoluminescing bubble (SBSL) in a liquid hammer device. In particular, we investigated the phosphoric acid-xenon system, in which pulses up to four orders of magnitude brighter than SBSL in water systems (about 10;{12} photons per pulse) have been previously reported [Chakravarty, Phys. Rev. E 69, 066317 (2004)]. We used stroboscopic photography and a Mie scattering technique in order to measure the radius evolution of the bubbles. Under adequate conditions we may position a bubble at the bottom of the tube (cavity) and a second bubble trapped at the middle of the tube (upper bubble). During its collapse, the cavity produces the compression of the liquid column. This compression drives impulsively the dynamics of the upper bubble. Our measurements reveal that the observed light emissions produced by the upper bubble are generated at its second collapse. We employed a simple numerical model to investigate the conditions that occur during the upper bubble collapse. We found good agreement between numerical and experimental values for the light intensity (fluence) and light pulse widths. Results from the model show that the light emission is increased mainly due to an increase in noble gas ambient radius and not because the maximum temperature increases. Even for the brightest pulses obtained ( 2x10;{13} photons, about 20W of peak power) the maximum temperatures computed for the upper bubble are always lower than 20000K .

Wind energy on the horizon in British Columbia. A review and evaluation of the British Columbia wind energy planning framework

NASA Astrophysics Data System (ADS)

Day, Jason

This study examines the wind energy planning frameworks from ten North American jurisdictions, drawing important lessons that British Columbia could use to build on its current model which has been criticized for its limited scope and restriction of local government powers. This study contributes to similar studies conducted by Kimrey (2006), Longston (2006), and Eriksen (2009). This study concludes that inclusion of wind resource zones delineated through strategic environmental assessment, programme assessment, and conducting research-oriented studies could improve the current British Columbia planning framework. The framework should also strengthen its bat impact assessment practices and incorporate habitat compensation. This research also builds upon Rosenberg's (2008) wind energy planning framework typologies. I conclude that the typology utilized in Texas should be employed in British Columbia in order to facilitate utilizing wind power. The only adaptation needed is the establishment of a cross-jurisdictional review committee for project assessment to address concerns about local involvement and site-specific environmental and social concerns.

Attitudes towards people with intellectual disabilities: a comparison of young people from British South Asian and White British backgrounds.

PubMed

Sheridan, Joel; Scior, Katrina

2013-04-01

Research with South Asian families of individuals with intellectual disabilities (ID) suggests an increased fear of stigma and isolation from the community. Evidence on attitudes towards ID among the wider community is very limited and was the focus of the present study. Responses were collected from 737 college students aged 16-19 using the Community Living Attitudes Scale-ID version. Results indicated that British South Asians (n=355) were less in favour of the social inclusion of people with ID than White British young people (n=382). British South Asian adolescents were more likely to hold the view that people with ID should be sheltered and not empowered. It is proposed that future inclusion policies integrate ethnic minority views whose religious and cultural values do not always conform to the core values of social inclusion policies. It is also proposed that culturally specific school based interventions could be introduced with the aims of decreasing stigma and fostering attitudes in line with the aims of normalisation.

Utilizing Bourdieu's concept of the habitus, Keith Macdonald has recently examined the elite social origins of the British officer corps. His analysis is valid as far at it goes but it ignores the professional practices of British officers. This article examines Britain's Joint Services Command and Staff College to assess the unification of the three services around common forms of military practice. It argues that while the new staff college has been effective in disseminating new forms of professional expertise among British officers, various practices have been institutionalized which actively undermine the unity of the officer corps.

The geodetic data set stems from a combination of re-processed continuous Global Positioning System (GPS) measurements from stations in the British Isles and from a global reference frame network, and absolute gravity (AG) measurements from two stations in the British Isles. The geologic data set of late Holocene sea level indicators has recently been updated, now applying corrections for the 20th century sea level rise, syphoning effect and late Holocene global ice melt, and expanded to Northern Ireland and Ireland. Several new model predictions of the glacial isostatic adjustment (GIA) process active in this region form the modelling data set of vertical land movements for the British Isles. Correcting the updated revised local reference (RLR) trends from the Permanent Service for Mean Sea Level (PSMSL) with these vertical land movement data sets, regional and averaged changes in sea levels around the British Isles have been investigated. Special focus is thereby also given to the coastal areas that have recently been identified within the UK Climate Projections 2009.

Hypothenar hammer syndrome from ice hockey stick-handling.

Zayed, Mohamed A; McDonald, Joey; Tittley, Jacques G

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.

Gender-specific attitudes and communication styles are known to influence both the content and outcome of medical visits. Therefore, gender-specific differences in response to cost containment may also occur. The purpose of this study was to assess the effect of physician gender on changes in prescribing patterns of angiotensin-converting enzyme (ACE) inhibitors after the implementation of reference pricing for prescription drugs in British Columbia, Canada. Reference pricing is a cost-sharing policy by which use of high-priced medication requires out-of-pocket payment of the price difference between the cost-sharing drug and a lower-cost drug within the same class. In British Columbia, reference pricing for ACE inhibitors was introduced on January 1, 1997. Analysis was carried out on linked pharmacy and medical service claims data on 927 female and 2922 male physicians treating 47,680 Pharmacare Plan A enrollees who were aged >-65 years and were prescribed a high-priced ACE inhibitors before the implementation of reference pricing. Female physicians (24.1% of all physicians) were younger, treated more female patients, had patients with fewer chronic illnesses, and worked more often as general practitioners than did male physicians. The patients of female physicians were more likely to receive a written physician-requested exemption from copayment, according to a multivariate logistic regression analysis (odds ratio [OR], 1.25; 95% CI, 1.04-1.50). Data suggested that patients of female physicians were more likely to stop antihypertensive drug therapy (OR, 1.43; 95% CI, 0.96-2.13); however, this was independent of the new copayment policy. The results provide empirical evidence that physician gender is associated with slightly different patient management strategies regarding physician-requested exemptions after the start of a new drug cost-sharing policy. However, these differences are unlikely to have meaningful clinical or economic consequences.

Tools of Thor - more than a hammer: An overview of some analysis methods for turbulence investigation

NASA Astrophysics Data System (ADS)

Haaland, Stein; Vaivads, Andris; Eriksson, Elin

2016-04-01

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

Abstract Background The checklist of British and Irish Ichneumonidae is revised, based in large part on the collections of the Natural History Museum, London and the National Museums of Scotland, Edinburgh. Distribution records are provided at the country level. New information Of the 2,447 species regarded as valid and certainly identified, 214 are here recorded for the first time from the British Isles. Neorhacodinae is considered to be a separate subfamily rather than a synonym of Tersilochinae. Echthrini is treated as a junior synonym of the tribe Cryptini, not Hemigastrini. Echthrus Gravenhorst and Helcostizus Förster are classified in Cryptini rather than, respectively, Hemigastrini and Phygadeuontini. PMID:27733812

Background Heat illness in the Armed Forces is considered preventable. The UK military relies upon dual Command and Medical reporting for case ascertainment, investigation of serious incidents and improvement of preventive practices and policy. This process could be vulnerable to under-reporting. Objectives To establish whether heat illness in the British Army has been under-reported, by reviewing concordance of reporting to the Army Incident Notification Cell (AINC) and the Army Health Unit (AHU) and to characterise the burden of heat illness reported by these means. Methods Analysis of anonymised reporting databases held by the AHU and AINC, for the period 2009–2013. Results 565 unique cases of heat illness were identified. Annual concordance of reporting ranged from 9.6% to 16.5%. The overall rate was 13.3%. July was the month with the greatest number of heat illness reports (24.4% of total reporting) and the highest concordance rate (30%). Reports of heat illness from the UK (n=343) exceeded overseas notifications (n=221) and showed better concordance (17.1% vs 12.8%). The annual rate of reported heat illness varied widely, being greater in full-time than reservist personnel (87 vs 23 per100 000) and highest in full-time untrained personnel (223 per100 000). Conclusions The risk of heat illness was global, year-round and showed dynamic local variation. Failure to dual-report casualties impaired case ascertainment of heat illness across Command and Medical chains. Current preventive guidance, as applied in training and on operations, should be critically evaluated to ensure that risk of heat illness is reduced as low as possible. Clear procedures for casualty notification and surveillance are required in support of this and should incorporate communication within and between the two reporting chains. PMID:25717054

The Expulsion of South Africa and Rhodesia from the Commonwealth Medical Association, 1947-70.

PubMed

Stewart, John

2017-10-01

In 1970 the medical associations of South Africa and Rhodesia (now, Zimbabwe) were expelled from the Commonwealth Medical Association. The latter had been set up, as the British Medical Commonwealth Medical Conference, in the late 1940s by the British Medical Association (BMA). These expulsions, and the events leading up to them, are the central focus of this article. The BMA's original intention was to establish an organisation bringing together the medical associations of the constituent parts of the expanding Commonwealth. Among the new body's preoccupations was the relationship between the medical profession and the state in the associations' respective countries. It thus has to be seen as primarily a medico-political organisation rather than one concerned with medicine per se. Although, there were also tensions from the outset regarding the membership of the Southern African medical associations. Such stresses notwithstanding, these two organisations remained in the BMA-sponsored body even after South Africa and Rhodesia had left the Commonwealth. This was not, however, a situation which could outlast the growing number of African associations which joined in the wake of decolonisation; and hardening attitudes towards apartheid. The article therefore considers: why the BMA set up this Commonwealth body in the first place and what it hoped to achieve; the history of the problems associated with South African and Rhodesian membership; and how their associations came to be expelled.

Several studies have shown a tight connection between several ocular pathologies and an increased risk of hip fractures due to falling, especially among elderly patients. The total replacement of the hip joint is a major surgical intervention that aims to restore the function of the affected hip by various factors, such as arthritis, injures, and others. A corkscrew-like femoral stem was designed in order to preserve the bone stock and to prevent the occurrence of iatrogenic fractures during the hammering of the implant. In this paper, the finite element analysis for the proposed design was applied, considering different loads and three types of materials. A finite element analysis is a powerful tool to simulate, optimize, design, and select suitable materials for new medical implants. The results showed that the best scenario was for Ti6Al4V alloy, although Ti and 316L stainless steel had a reasonable high safety factor.

2007-11-01

Hypothenar hammer syndrome (HHS) is an uncommon form of secondary Raynaud phenomenon, occurring mainly in subjects who use the hypothenar part of the hand as a hammer; the hook of the hamate strikes the superficial palmar branch of the ulnar artery in the Guyon space, leading to occlusion and/or aneurysm of the ulnar artery. In patients with HHS, such injuries of the palmar ulnar artery may lead to severe vascular insufficiency in the hand with occlusion of digital artery. To date, only a few series have analyzed the long-term outcome of patients with HHS. This prompted us to conduct the current retrospective study to 1) evaluate the prevalence of HHS in patients with Raynaud phenomenon and 2) assess the short-term and long-term outcome in patients with HHS. From 1990 to 2006, 4148 consecutive patients were referred to the Department of Internal Medicine at the University of Rouen medical center for evaluation of Raynaud phenomenon using nailfold capillaroscopy. HHS was diagnosed in 47 of these 4148 patients (1.13% of cases).Forty-three patients (91.5%) had occupational exposure to repetitive palmar trauma. The more common occupations were factory worker (21.3%), mason (12.8%), carpenter (10.6%), and metal worker (10.6%); the mean duration of occupational exposure to repetitive palmar trauma at HHS diagnosis was 21 years. One patient (2.1%) had recreational exposure (aikido training) to repetitive trauma of the palmar ulnar artery, and 3 other patients (6.4%) developed HHS related to a single direct injury to the hypothenar area. Clinical manifestations were more often unilateral (87.2%) involving the dominant hand (93%). HHS complications included digital ischemic symptoms (ischemia: n = 21, necrosis: n = 20) and irritation of the sensory branch of the ulnar nerve (n = 11). In HHS patients, angiography demonstrated occlusion of the ulnar artery in the area of the Guyon space (59.6%), aneurysm of the ulnar artery in the area of the Guyon space (40.4%), and embolic

J.G. Crowther's War: Institutional strife at the BBC and British Council.

PubMed

Jones, Allan

2016-06-01

Science writer, historian and administrator J.G. Crowther (1899-1983) had an uneasy relationship with the BBC during the 1920s and 1930s, and was regarded with suspicion by the British security services because of his left politics. Nevertheless the Second World War saw him working for 'establishment' institutions. He was closely associated with the BBC's Overseas Service and employed by the British Council's Science Committee. Both organizations found Crowther useful because of his wide, international knowledge of science and scientists. Crowther's political views, and his international aspirations for the British Council's Science Committee, increasingly embroiled him in an institutional conflict with the Royal Society and with its president, Sir Henry Dale, who was also chairman of the British Council's Science Committee. The conflict centred on the management of international scientific relations, a matter close Crowther's heart, and to Dale's. Dale considered that the formal conduct of international scientific relations was the Royal Society's business rather than the British Council's. Crowther disagreed, and eventually resigned from the British Council Science Committee in 1946. The article expands knowledge of Crowther by drawing on archival documents to elucidate a side of his career that is only lightly touched on in his memoirs. It shows that 'Crowther's war' was also an institutional war between the Science Committee of the British Council and the Royal Society. Crowther's unhappy experience of interference by the Royal Society plausibly accounts for a retreat from his pre-war view that institutional science should plan and manage BBC science broadcasts.

Boleslas Matuszewski, born in 1856, was a pioneer in medical film-making. He worked simultaneously on improving his movie camera, film-making, collecting film documentation, and the idea of establishing an archive of medical films. Although his first attempts at filming and showing surgical operations didn't gain widespread approval, he was not discouraged, and succeeded in garnering support from a number of French doctors, who realised the importance of his ideas, not only in filming and forming medical film documentation, but also in the use of film for educative purposes. His visionary ideas gained acceptance when Dr. Doyen, on the occasion of the 66th Convention of the British Medical Society, in 1898, used film material as part of his lecture. Shortly afterwards, the Medical Academy took steps to show certain operative techniques, which represented both the confirmation and fruition of Matuszewski's ideas about filmmaking and the establishment of an archive of medical films.

The Schmidt hammer as a relative-age dating tool and its potential for calibrated-age dating in Holocene glaciated environments

NASA Astrophysics Data System (ADS)

Shakesby, Richard A.; Matthews, John A.; Owen, Geraint

2006-11-01

The Schmidt hammer is a relatively cheap, portable, sturdy instrument with proven value over the last two decades or so in rapidly dating coarse inorganic deposits of diverse origins. Early views were that its dating role was limited to distinguishing recently exposed from much older. Typically, either a few sites of possibly different ages or occasional older surfaces amongst many young sites were studied. More recently, calibration curves based on individual R-value means from small numbers (2-4) of sites of known ages have been used to estimate the ages of undated sites. We present Schmidt hammer rebound ( R-) values from 28 'Little Ice Age' (and younger), 23 Preboreal and 7 Younger Dryas glaciated surfaces in southern Norway in order, first, to test rigorously the robustness of the instrument as a relative-age dating tool. Despite being obtained from different surfaces (moraines, glaciofluvial deposits and bedrock) and varied metamorphic lithologies, the R-value overall means and 95% confidence intervals for the 'Little Ice Age', Preboreal and Younger Dryas age categories (respectively, 60.0±1.6, 41.6±1.4 and 34.2±2.0) are statistically significantly different. Only two outlying sites in the two younger age categories have overlapping confidence intervals, demonstrating remarkable robustness in differentiating early- and late-Holocene surfaces. The distinction between Preboreal and Younger Dryas sites (with terminal dates <2000 years apart) is less clear but still statistically significant, though possibly partly because of enhanced weathering conditions at the predominantly well vegetated Younger Dryas sites. Second, we examine the feasibility and desirability of controlling non-age-related factors, including some previously considered critical (instrument wear, operator bias, initial rock surface texture), which emerge either as less important than previously argued or as relatively unimportant, together with others previously unreported (e.g. long

The agreement will see British Gas replace four 35-year-old gas-powered steam boilers and an ageing CHP plant in the boiler house at the Trust's main acute facility, the StGeorge's Hospital in Tooting, and upgrade some of the associated infrastructure. British Gas will also maintain the new plant to ensure that the projected savings are achieved while the Trust owns the new assets. The Trust should gain financially--via lower energy costs and carbon emissions, while estates personnel will be better able to complete the many other estate maintenance issues that would otherwise be contracted out at one of London's biggest acute hospitals.

A journey to citizenship: constructions of citizenship and identity in the British Citizenship Test.

PubMed

Gray, Debra; Griffin, Christine

2014-06-01

The British Citizenship Test was introduced in 2005 as one of a raft of new procedures aimed at addressing the perceived problems of integration and social cohesion in migrant communities. In this study, we argue that this new citizenship procedure signals a shift in British political discourse about citizenship - particularly, the institutionalization of a common British citizen identity that is intended to draw citizens together in a new form of political/national community. In line with this, we examine the British Citizenship Test from a social psychological perspective to interrogate the ways in which the test constitutes identity, constitutes citizenship, and constitutes citizenship-as-identity. Analysis of the test and its associated documents highlights three ways in which Britishness-as-identity is constituted, that is, as a collective identity, as a superordinate and national identity, and finally as both a destination and a journey. These findings are discussed in terms of their implications for models of citizenship and models of identity. © 2013 The British Psychological Society.

Characteristics and origin of coarse gold in Late Pleistocene sediments of the Cariboo placer mining district, British Columbia, Canada

NASA Astrophysics Data System (ADS)

Eyles, N.

1995-02-01

The Cariboo placer mining district (1000 km 2) sited in the Interior Plateau of central British Columbia, Canada, is the premier placer gold mining district of the Province. Gold is recovered from three Late Pleistocene sedimentary facies: postglacial fluvial gravels (< 10 Ka), Late Wisconsin till (ca. 25-10 Ka), and "older" fluvial gravels (>25 Ka). This study reports the morphology (size, roundness, sphericity) of 1636 gold grains, ranging in size from 0.25 to 17 mm, recovered from 19 placer mines. Older gravels contain the smallest gold grains (mean grani size 1.53 mm), grains of intermediate size occur in till (2.23 mm) and the coarsest gold occurs in postglacial gravels (2.34 mm) with a mean of 1.93 mm for the mining district as a whole. The most common grain shapes are sub-rounded, discoidal (14.73% of the grain population), sub-angular, discoidal (10.88%), and sub-rounded, sub-discoidal (9.59%); the most angular grains occur in postglacial gravels. In-situ growth of coarse, angular grains is indicated by a "composite" grain structure, consisting of aggregates of gold particles welded together by high-grade (Ag = < 2%) filamentous gold; in-situ coarsening may be reliant on organic complexing agents produced below a dense forest cover. An evolutionary sequence of grain form, from angular aggregates to rounded "pumpkin seed" grains, is suggested. Rounded grains commonly show a crystalline structure which may result from the cold hammering of gold during transport; fracturing along crystal boundaries is common. Gold grains may undergo cycles of coarsening, rounding, diagenesis and breakup in response to repeated recycling through Pleistocene sedimentary environments.

Validity of the Water Hammer Formula for Determining Regional Aortic Pulse Wave Velocity: Comparison of One-Point and Two-Point (Foot-to-Foot) Measurements Using a Multisensor Catheter in Human.

PubMed

Hanya, Shizuo

2013-01-01

Lack of high-fidelity simultaneous measurements of pressure and flow velocity in the aorta has impeded the direct validation of the water-hammer formula for estimating regional aortic pulse wave velocity (AO-PWV1) and has restricted the study of the change of beat-to-beat AO-PWV1 under varying physiological conditions in man. Aortic pulse wave velocity was derived using two methods in 15 normotensive subjects: 1) the conventional two-point (foot-to-foot) method (AO-PWV2) and 2) a one-point method (AO-PWV1) in which the pressure velocity-loop (PV-loop) was analyzed based on the water hammer formula using simultaneous measurements of flow velocity (Vm) and pressure (Pm) at the same site in the proximal aorta using a multisensor catheter. AO-PWV1 was calculated from the slope of the linear regression line between Pm and Vm where wave reflection (Pb) was at a minimum in early systole in the PV-loop using the water hammer formula, PWV1 = (Pm/Vm)/ρ, where ρ is the blood density. AO-PWV2 was calculated using the conventional two-point measurement method as the distance/traveling time of the wave between 2 sites for measuring P in the proximal aorta. Beat-to-beat alterations of AO-PWV1 in relationship to aortic pressure and linearity of the initial part of the PV-loop during a Valsalva maneuver were also assessed in one subject. The initial part of the loop became steeper in association with the beat-to-beat increase in diastolic pressure in phase 4 during the Valsalva maneuver. The linearity of the initial part of the PV-loop was maintained consistently during the maneuver. Flow velocity vs. pressure in the proximal aorta was highly linear during early systole, with Pearson's coefficients ranging from 0.9954 to 0.9998. The average values of AO-PWV1 and AO-PWV2 were 6.3 ± 1.2 and 6.7 ± 1.3 m/s, respectively. The regression line of AO-PWV1 on AO-PWV2 was y = 0.95x + 0.68 (r = 0.93, p <0.001). This study concluded that the water-hammer formula (one-point method) provides

Part of a global workforce: migration of British-trained pharmacists.

Many countries, including the UK, have identified a shortage of pharmacists, partly due to emigration. This study was undertaken to examine the extent and nature of migration taking place among British-qualified pharmacists. Mixed methods, including secondary analysis of quantitative data, qualitative research and a large self-completion survey of all British-registered pharmacists with an overseas address. Almost 11% of British-registered pharmacists reside overseas. Nearly three-quarters are British-trained and most are UK nationals. The US, Canada and Australia are the main destinations. The majority work as pharmacists in health services, but sizeable proportions are either retired, not working for other reasons or work in industry. Those who emigrate include those returning home, moving for career opportunities, for lifestyle reasons or as a 'spouse trailer'. For many the move abroad is a permanent one. Great Britain is both a source and destination country for migrating pharmacists. Emigration currently exceeds immigration. Pharmacists are not migrating to developing countries, so the profession may want to consider ways of contributing to the health care systems in developing countries which are the source of some of the immigrant pharmacists to Great Britain.

Anderson, Stacey J; Millett, Christopher; Polansky, Jonathan R; Glantz, Stanton A

2010-06-01

To estimate youth exposure to smoking in movies in the UK and compare the likely effect with the USA. We collected tobacco occurrences data for 572 top-grossing films in the UK screened from 2001 to 2006 and estimated the number of on-screen tobacco impressions delivered to British youths in this time period. 91% of films in our sample that contained smoking were youth-rated films (British Board of Film Classification rating '15' and lower), delivering at least 1.10 billion tobacco impressions to British youths during theatrical release. British youths were exposed to 28% more smoking impressions in UK youth-rated movies than American youth-rated movies, because 79% of movies rated for adults in the USA ('R') are classified as suitable for youths in the UK ('15' or '12A'). Because there is a dose-response relation between the amount of on-screen exposure to smoking and the likelihood that adolescents will begin smoking, the fact that there is substantially higher exposure to smoking in youth-rated films in the UK than in the USA suggests that the fraction of all youth smoking because of films in the UK is probably larger than in the USA. Other countries with ratings systems that are less conservative (in terms of language and sexuality) than the USA will also be likely to deliver more on-screen tobacco impressions to youths. Assigning an '18' classification to movies that contain smoking would substantially reduce youth exposure to on-screen smoking and, hence, smoking initiation among British youths.

Kanagala, P; Bradley, C; Hoffman, P; Steeds, R P

2011-10-01

The clinical utility of transoesophageal echocardiography (TOE) is well established. Being a semi-invasive procedure, however, the potential for transmission of infection between sequential patients exists. This has implications for the protection of both patients and medical staff. Guidelines for disinfection during gastrointestinal endoscopy (GIE) have been in place for many years.(1,2) Unfortunately, similar guidance is lacking with respect to TOE. Although traversing the same body cavities and sharing many similarities with upper GIE, there are fundamental structural and procedural differences with TOE which merit special consideration in establishing a decontamination protocol. This document provides recommendations for TOE probe decontamination based on the available evidence, expert opinion, and modification of the current British Society of Gastroenterology guidelines.

Making short-term international medical volunteer placements work: a qualitative study.

International medical volunteering has grown in recent decades. It has the potential to benefit and harm the volunteer and host countries; but there is a paucity of literature on the impacts of international medical volunteering and a need to find ways to optimise the benefits of such placements. In this study, one example of international medical volunteering was examined involving British GPs on short-term placements in Nepal. The intention was to explore the expectations and experiences of the local health workers, volunteers, and host organisation to try and understand what makes volunteer placements work. Qualitative study of key informant interviews. Stakeholders of a short-term international medical volunteer (IMV) placement programme in Nepal. Key informant interviews were carried out via face-to-face or telephone/internet interviews with five previous volunteers, three representatives from a non-governmental organisation providing placements, and five local health workers in Nepal who had had contact with the IMVs. Interviews were recorded, transcribed, and analysed using standard thematic framework approaches. All the stakeholders had their own specific motives for participating in the IMV programme. The relationship between volunteers and the Nepalese health workers was complex and characterised by discrepant and occasionally unrealistic expectations. Managing these different expectations was challenging. Contextual issues and cultural differences are important considerations in medical volunteer programmes, and this study highlights the importance of robust preparation pre-placement for the volunteer and host to ensure positive outcomes. © British Journal of General Practice 2014.

Skull wounds linked with blunt trauma (hammer example). A report of two depressed skull fractures--elements of biomechanical explanation.

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.

The medical needs of older people are growing because the proportion of the older population is increasing and disease boundaries are widening. This study describes the distribution and clustering of 15 common clinical disorders requiring medical treatment or supervision in a representative British cohort approaching retirement, and how health tracked across adulthood. The data come from a cohort of 2661 men and women, 84% of the target sample, followed since birth in England, Scotland and Wales in 1946, and assessed at 60-64 years for: cardio and cerebro-vascular disease, hypertension, raised cholesterol, renal impairment, diabetes, obesity, hypothyroidism, hyperthyroidism, anaemia, respiratory disease, liver disease, psychiatric problems, cancers, atrial fibrillation on ECG and osteoporosis. We calculated the proportions disorder-free, with one or more disorders, and the level of undiagnosed disorders; and how these disorders cluster into latent classes and relate to health assessed at 36 years. Participants had, on average, two disorders (range 0-9); only 15% were disorder-free. The commonest disorders were hypertension (54.3%, 95% CI 51.8%-56.7%), obesity (31.1%, 28.8%-33.5%), raised cholesterol (25.6%, 23.1-28.26%), and diabetes or impaired fasting glucose (25.0%, 22.6-27.5%). A cluster of one in five individuals had a high probability of cardio-metabolic disorders and were twice as likely than others to have been in the poorest health at 36 years. The main limitations are that the native born sample is entirely white, and a combination of clinical assessments and self reports were used. Most British people reaching retirement already have clinical disorders requiring medical supervision. Widening disease definitions and the move from a disease-based to a risk-based medical model will increase pressure on health services. The promotion of healthy ageing should start earlier in life and consider the individual's ability to adapt to and self manage changes in

Commentary from Westminster. Medical effects of nuclear war.

Deitch, R

1983-03-12

A British Medical Association report on the medical consequences of nuclear war, scheduled for commercial publication in April 1983, could damage the Government's arguments for maintaining a nuclear deterrent. The gist of the BMA's findings is that Britain could not possibly cope with the aftermath of nuclear attack. Although Prime Minister Thatcher has made no comment, both the Home Office and the Department of Health and Social Security have criticized the report's negative conclusions. The BMA is expected to take up the issue at its annual meeting, and the Labour party has called for a Parliamentary debate on the report and its implications.

"Mended or ended?" Football injuries and the British and American medical press, 1870-1910.

Park, R J

2001-01-01

'Playing Hurt/Playing Tough', a dominant ideology in today's football (soccer, rugby, American 'gridiron'), is by no means new. Many books, monographs, and articles have examined the historical development of these games, but the attention given to them in the medical press during the late 1800s/early 1900s has been overlooked. The Lancet, Journal of the American Medical Association, and other turn-of-the-century medical publications regularly included accounts and descriptions of injuries and deaths. More telling were the many editorials in which physicians in both Britain and the United States expressed enthusiasm while also lamenting the games' physical and morale effects upon players, asking whether 'football' should be mended or ended.

Background Pharmaceutical advertisements have been argued to provide revenue that medical journals require but they are intended to alter prescribing behaviour and they are known to include low quality information. We determined whether a difference exists in the current level of pharmaceutical advertising in print general medical journals, and we estimated the revenue generated from print pharmaceutical advertising. Methods Six print general medical journals in Canada, the United States, and the United Kingdom were sampled between 2007 and 2012. The number of advertisements and other journal content in selected issues of the Canadian Medical Association Journal (CMAJ), Canadian Family Physician (CFP), Journal of the American Medical Association (JAMA), New England Journal of Medicine (NEJM), British Medical Journal (BMJ), and Lancet were determined. Revenue gained from pharmaceutical advertising was estimated using each journal's 2013 advertising price list. Findings The two Canadian journals sampled (CMAJ, CFP) contained five times more advertisements than the two American journals (JAMA, NEJM), and two British journals (BMJ, Lancet) (p<0.0001). The estimated annual revenue from pharmaceutical advertisements ranged from £0.025 million (for Lancet) to £3.8 million (for JAMA). The cost savings due to revenue from pharmaceutical advertising to each individual subscriber ranged from £0.02 (for Lancet) to £3.56 (for CFP) per issue. Conclusion The volume of pharmaceutical advertisements differs between general medical journals, with the two Canadian journals sampled containing the most advertisements. International and temporal variations suggest that there is an opportunity for all general medical journals to reduce the number of pharmaceutical advertisements, explore other sources of revenue, and increase transparency regarding sources of revenue.

Three thousand families: English Canada's colonizing vision and British family settlement, 1919-39.

Mancuso, Rebecca J

2011-01-01

After the First World War, Canada's immigration policy became more restrictive and immigration more controlled. For English Canadians, immigration of the "right type" of people—those from the British Isles—remained vital to strengthening the nation. This article examines the 3,000 Family Scheme, a joint British-Canadian settlement project in which British families, comprised of over 18,000 individuals, were relocated to homesteads as colonizers of Canada's remote areas. There, many endured isolation and hardship, and were largely blamed for their own plight. A nation-building project that failed, the 3,000 Family Scheme reveals the connections among several enduring national myths in the interwar years: the potential for agricultural expansion, British superiority, and the capabilities of a maturing Canadian state to control the settlement process.

Water hammer effect in the spiral case and penstock of Francis turbines

NASA Astrophysics Data System (ADS)

Pepa, D.; Ursoniu, C.; Gillich, R. N.; Campian, C. V.

2017-01-01

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.

The Expulsion of South Africa and Rhodesia from the Commonwealth Medical Association, 1947–70

PubMed Central

Stewart, John

2017-01-01

In 1970 the medical associations of South Africa and Rhodesia (now, Zimbabwe) were expelled from the Commonwealth Medical Association. The latter had been set up, as the British Medical Commonwealth Medical Conference, in the late 1940s by the British Medical Association (BMA). These expulsions, and the events leading up to them, are the central focus of this article. The BMA’s original intention was to establish an organisation bringing together the medical associations of the constituent parts of the expanding Commonwealth. Among the new body’s preoccupations was the relationship between the medical profession and the state in the associations’ respective countries. It thus has to be seen as primarily a medico-political organisation rather than one concerned with medicine per se. Although, there were also tensions from the outset regarding the membership of the Southern African medical associations. Such stresses notwithstanding, these two organisations remained in the BMA-sponsored body even after South Africa and Rhodesia had left the Commonwealth. This was not, however, a situation which could outlast the growing number of African associations which joined in the wake of decolonisation; and hardening attitudes towards apartheid. The article therefore considers: why the BMA set up this Commonwealth body in the first place and what it hoped to achieve; the history of the problems associated with South African and Rhodesian membership; and how their associations came to be expelled.

Short communications published online in the British Journal of Oral and Maxillofacial Surgery during 2010-2011.

2012-09-01

The British Journal of Oral and Maxillofacial Surgery (BJOMS) publishes many types of papers including original articles, review articles, and short communications. Many of the latter are isolated case reports of rare or interesting diseases or of difficult or unexpected complications. While case reports are sometimes considered to be of little educational or clinical value, and as such do little to advance medical knowledge, they do have an important role, and many trainees begin their publishing careers writing such papers. There is increasing pressure for space in paper medical journals and, for this reason, some journals either limit or do not publish short publications in print copy but instead put them online. Using established criteria, we previously evaluated all 142 short communications published in the BJOMS during 2008-2009 and found that 48% of them had little or no educational value. As a result, the editorial board of BJOMS took the decision to publish most short communications online only. We have now analysed 48 short communications that were published online only during 2010-2011. Most (80%) were single case reports that covered virtually the whole remit of the specialty, and over half (56%) were published by authors based in the UK. While many of these papers did not add important new information to existing knowledge, these types of article are clearly of value both for trainees and for experienced surgeons. We think that these should continue to be supported as, in addition to their educational value, they are an excellent way for trainees to start to write.

Trained sensory panels in Britain and Spain assessed loin meat from commercial lambs purchased in Spain, which included Welsh lamb (imported from Britain) and two Spanish breeds (Merino and Rasa Aragonesa). The British panel also assessed British lamb purchased in local butcher shops and supermarkets. Sensory panels, in each country, received meat from the same lambs and used their local methods of cooking and assessment. Spanish panels used unstructured line scales to measure lamb odour intensity, tenderness, juiciness, lamb flavour intensity and two hedonic scales of flavour liking and overall liking. The British panel used 8 point category scales with the same attributes. Results from both panels in objective parameters were in agreement, hence showing that different trained sensory panels may arrive at the same conclusion. However, when panellists were allowed to make hedonic judgements (preference), the British panel preferred British lamb and the Spanish panel preferred Spanish lamb. This finding has important consequences for lamb producers who export their lambs and demonstrates that the underlying reasons for different preferences should be investigated. Production variables are discussed in relation to their influence on lamb eating quality and as a way to tailor lamb eating quality attributes familiar to consumers in the importing country.

2017-04-01

To examine variation in pharmaceutical spending and patient characteristics across prescription drug user groups. British Columbia's population-based linked administrative health and sociodemographic databases (N = 3,460,763). We classified individuals into empirically derived prescription drug user groups based on pharmaceutical spending patterns outside hospitals from 2007 to 2011. We examined variation in patient characteristics, mortality, and health services usage and applied hierarchical clustering to determine patterns of concurrent drug use identifying high-cost patients. Approximately 1 in 20 British Columbians had persistently high prescription costs for 5 consecutive years, accounting for 42 percent of 2011 province-wide pharmaceutical spending. Less than 1 percent of the population experienced discrete episodes of high prescription costs; an additional 2.8 percent transitioned to or from high-cost episodes of unknown duration. Persistent high-cost users were more likely to concurrently use multiple chronic medications; episodic and transitory users spent more on specialized medicines, including outpatient cancer drugs. Cluster analyses revealed heterogeneity in concurrent medicine use within high-cost groups. Whether low, moderate, or high, costs of prescription drugs for most individuals are persistent over time. Policies controlling high-cost use should focus on reducing polypharmacy and encouraging price competition in drug classes used by ordinary and high-cost users alike. © 2016 The Authors.

Electricity and Empire in 1920s Palestine under British Rule.

Shamir, Ronen

2016-12-01

This article examines some techno-political aspects of the early years of electrification in British-ruled 1920s Palestine. It emphasizes the importance of local technical, topographical and hydrological forms of knowledge for understanding the dynamics of electrification. Situating the analysis in a general colonial context of electrification, the study shows that British colonial rulers lagged behind both German firms and local entrepreneurs in understanding the specific conditions pertaining to electrification in Palestine. Subsequently, the study shows that the British had limited control of the actual electrification process and its declared/professed developmental purposes, thereby complicating assumptions about electrification as a tool of the Empire/tool of empire. Finding some similarities between the cases of electrifying Palestine and India, the article's findings may shed further light on the importance of micro-politics of knowledge for understanding the trajectory of electrification in the colonies.

Did the perils of abdominal obesity affect depiction of feminine beauty in the sixteenth to eighteenth century British literature? Exploring the health and beauty link

PubMed Central

Singh, Devendra; Renn, Peter; Singh, Adrian

2007-01-01

‘Good gene’ mate selection theory proposes that all individuals share evolved mental mechanisms that identify specific parts of a woman's body as indicators of fertility and health. Depiction of feminine beauty, across time and culture, should therefore emphasize the physical traits indicative of health and fertility. Abdominal obesity, as measured by waist size, is reliably linked to decreased oestrogen, reduced fecundity and increased risk for major diseases. Systematic searches of British literature across the sixteenth, seventeenth and eighteenth centuries reveal that a narrow waist is consistently described as beautiful. Works in ancient Indian and Chinese literature similarly associate feminine attractiveness with a narrow waist. Even without the benefit of modern medical knowledge, both British and Asian writers knew intuitively the biological link between health and beauty. PMID:17251110

Validity of the Water Hammer Formula for Determining Regional Aortic Pulse Wave Velocity: Comparison of One-Point and Two-Point (Foot-to-Foot) Measurements Using a Multisensor Catheter in Human

PubMed Central

2013-01-01

Background: Lack of high-fidelity simultaneous measurements of pressure and flow velocity in the aorta has impeded the direct validation of the water-hammer formula for estimating regional aortic pulse wave velocity (AO-PWV1) and has restricted the study of the change of beat-to-beat AO-PWV1 under varying physiological conditions in man. Methods: Aortic pulse wave velocity was derived using two methods in 15 normotensive subjects: 1) the conventional two-point (foot-to-foot) method (AO-PWV2) and 2) a one-point method (AO-PWV1) in which the pressure velocity-loop (PV-loop) was analyzed based on the water hammer formula using simultaneous measurements of flow velocity (Vm) and pressure (Pm) at the same site in the proximal aorta using a multisensor catheter. AO-PWV1 was calculated from the slope of the linear regression line between Pm and Vm where wave reflection (Pb) was at a minimum in early systole in the PV-loop using the water hammer formula, PWV1 = (Pm/Vm)/ρ, where ρ is the blood density. AO-PWV2 was calculated using the conventional two-point measurement method as the distance/traveling time of the wave between 2 sites for measuring P in the proximal aorta. Beat-to-beat alterations of AO-PWV1 in relationship to aortic pressure and linearity of the initial part of the PV-loop during a Valsalva maneuver were also assessed in one subject. Results: The initial part of the loop became steeper in association with the beat-to-beat increase in diastolic pressure in phase 4 during the Valsalva maneuver. The linearity of the initial part of the PV-loop was maintained consistently during the maneuver. Flow velocity vs. pressure in the proximal aorta was highly linear during early systole, with Pearson’s coefficients ranging from 0.9954 to 0.9998. The average values of AO-PWV1 and AO-PWV2 were 6.3 ± 1.2 and 6.7 ± 1.3 m/s, respectively. The regression line of AO-PWV1 on AO-PWV2 was y = 0.95x + 0.68 (r = 0.93, p <0.001). Conclusion: This study concluded that the

Single Piezo-Actuator Rotary-Hammering Drill

NASA Technical Reports Server (NTRS)

Sherrit, Stewart; Bao, Xiaoqi; Badescu, Mircea; Bar-Cohen, Yoseph

2011-01-01

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 Powerful Protector of the Japanese People: The History of the Japanese Hospital in Steveston, British Columbia, Canada,18961942.

Vandenberg, Helen

2017-01-01

From 1896 to 1942, a Japanese hospital operated in the village of Steveston, British Columbia, Canada. For the first 4 years, Japanese Methodist missionaries utilized a small mission building as a makeshift hospital, until a larger institution was constructed by the local Japanese Fishermen's Association in 1900. The hospital operated until the Japanese internment, after the attack on Pearl Harbor during World War II. This study offers important commentary about the relationships between health, hospitals, and race in British Columbia during a period of increased immigration and economic upheaval. From the unique perspective of Japanese leaders, this study provides new insight about how Japanese populations negotiated hospital care, despite a context of severe racial discrimination. Japanese populations utilized Christianization, fishing expertise, and hospital work to garner more equitable access to opportunities and resources. This study demonstrates that in addition to providing medical treatment, training grounds for health-care workers, and safe refuge for the sick, hospitals played a significant role in confronting broader racialized inequities in Canada's past.

Is Smoking Behavior Culturally Determined? Evidence from British Immigrants*

PubMed Central

Lillard, Dean R.

2015-01-01

We exploit migration patterns from the UK to Australia and the US to investigate whether a person's decision to smoke is determined by culture. For each country, we use retrospective data to describe individual smoking trajectories over the life-course. For the UK, we use these trajectories to measure culture by cohort and cohort-age, and more accurately relative to the extant literature. Our proxy predicts smoking participation of second-generation British immigrants but not that of non-British immigrants and natives. Researchers can apply our strategy to estimate culture effects on other outcomes when retrospective or longitudinal data are available. PMID:25620826

Burdon, Paul; Dipper, Lucy; Cocks, Naomi

2016-09-01

Social perception is an important skill. One assessment that is commonly used to assess social perception abilities is The Awareness of Social Inference Test (TASIT). The only normative data available for this test are for Australian younger adults. Despite no normative data being available for British adults, the test is widely used in the UK with older and younger adults. There is a growing body of research that suggests that older adults have difficulty with skills associated with social perception. There is therefore a need to determine whether British adults, and more specifically British older adults, perform similarly to the Australian normative TASIT scores available in the manual. To explore the differences between older and younger British adults' performance on TASIT, and to determine whether younger and older British adults perform similarly to the data from Australian adults in TASIT manual. TASIT was administered to a total of 42 native British English speaking participants. The participants were split into two age groups 18-45 and 60-90 years. Comparisons were made between the two groups and the Australian data in TASIT manual. The younger British and Australian adults obtained similar scores on all parts of TASIT. The older British adults though, obtained significantly lower scores than the Australian younger adults on all parts of TASIT and when education was controlled for they obtained significantly lower scores than the British younger adults. The findings are discussed in the light of previous research that has found that older adults are worse than younger adults at social inferences. The findings of the current study suggest that caution should be used when using TASIT with older British adults to assess social perception abilities. © 2016 Royal College of Speech and Language Therapists.

Abstract Objective To explore the experiences of family physicians and pediatricians delivering immunizations, including perceived barriers and supports. Design Qualitative study using focus groups. Setting Ten cities throughout British Columbia. Participants A total of 46 family physicians or general practitioners, 10 pediatricians, and 2 residents. Methods A semistructured dialogue guide was used by a trained facilitator to explore participants’ experiences and views related to immunization delivery in British Columbia. Verbatim transcriptions were independently coded by 2 researchers. Key themes were analyzed and identified in an iterative manner using interpretive description. Main findings Physicians highly valued vaccine delivery. Factors facilitating physician-delivered immunizations included strong beliefs in the value of vaccines and having adequate information. Identified barriers included the large time commitment and insufficient communication about program changes, new vaccines, and the adult immunization program in general. Some physicians reported good relationships with local public health, while others reported the opposite experience, and this varied by geographic location. Conclusion These findings suggest that physicians are supportive of delivering vaccines. However, there are opportunities to improve the sustainability of physician-delivered immunizations. While compensation schemes remain under the purview of the provincial governments, local public health authorities can address the information needs of physicians. PMID:24627403

The 50th Annual Scientific Meeting of the British Society for Haematology was notable, not only for its golden anniversary, but also because it coincided with the eruption of the Icelandic volcano, Eyjafjallajökull, and the ensuing travel chaos. In total, 28 speakers from overseas were unable to reach Edinburgh, including a significant number of British speakers who were stranded. However, owing to the superb efforts of the conference organisers and Edinburgh International Conference Centre staff, teleconferencing equipment was installed and all speakers were contacted and able to give their talks on time. The program, consisting of simultaneous sessions and plenary lectures, covered not only recent advances in clinical and laboratory hematology, but also reflected on the contribution of British hematology to the international arena over the past 50 years.

Best practice guidelines for the management of frailty: a British Geriatrics Society, Age UK and Royal College of General Practitioners report.

PubMed

Turner, Gill; Clegg, Andrew

2014-11-01

Older people are majority users of health and social care services in the UK and internationally. Many older people who access these services have frailty, which is a state of vulnerability to adverse outcomes. The existing health care response to frailty is mainly secondary care-based and reactive to the acute health crises of falls, delirium and immobility. A more proactive, integrated, person-centred and community-based response to frailty is required. The British Geriatrics Society Fit for Frailty guideline is consensus best practice guidance for the management of frailty in community and outpatient settings. The BGS recommends that all encounters between health and social care staff and older people in community and outpatient settings should include an assessment for frailty. A gait speed <0.8m/s; a timed-up-and-go test >10s; and a score of ≥3 on the PRISMA 7 questionnaire can indicate frailty. The common clinical presentations of frailty (falls, delirium, sudden immobility) can also be used to indicate the possible presence of frailty. The BGS recommends an holistic medical review based on the principles of comprehensive geriatric assessment (CGA) for all older people identified with frailty. This will: diagnose medical illnesses to optimise treatment; apply evidence-based medication review checklists (e.g. STOPP/START criteria); include discussion with older people and carers to define the impact of illness; work with the older person to create an individualised care and support plan. The BGS does not recommend population screening for frailty using currently available instruments. © The Author 2014. Published by Oxford University Press on behalf of the British Geriatrics Society.

High-altitude environments lead to a significant physiological challenge and disease processes which can be life threatening; operational effectiveness at high altitude can be severely compromised. The UK military research is investigating ways of mitigating the physiological effects of high altitude. The British Service Dhaulagiri Research Expedition took place from March to May 2016, and the military personnel were invited to consent to a variety of study protocols investigating adaptation to high altitudes and diagnosis of high-altitude illness. The studies took place in remote and austere environments at altitudes of up to 7500 m. This paper gives an overview of the individual research protocols investigated, the execution of the expedition and the challenges involved. 129 servicemen and women were involved at altitudes of up to 7500 m; 8 research protocols were investigated. The outputs from these studies will help to individualise the acclimatisation process and inform strategies for pre-acclimatisation should troops ever need to deploy at high altitude at short notice.

To identify and explore features of ethical issues that senior clinicians faced as deployed medical directors (DMDs) to the British Field Hospital in Afghanistan as well as to determine the ethical training requirements for future deployments. A qualitative study in two phases conducted from November 2014 to June 2015. Phase 1 analysed 60 vignettes of cases that had generated ethical dilemmas for DMDs. Phase 2 included focus groups and an interview with 13 DMDs. Phase 1 identified working with limited resources, dual conflict of meeting both clinical and military obligations and consent of children as the most prevalent ethical challenges. Themes found in Phase 2 included sharing clinical responsibilities with clinicians from other countries and not knowing team members' ways of working, in addition to the themes from Phase 1. This study has drawn together examples of scenarios to form a repository that will aid future training. Recommendations included undertaking ethics training together as a team before, during and after deployment which must include all nationalities who are assigned to the same operational tour, so that different ethical views can be explored beforehand.

Flood Hazard Management: British and International Perspectives

NASA Astrophysics Data System (ADS)

James, L. Douglas

This proceedings of an international workshop at the Flood Hazard Research Centre (Queensway, Enfield, Middlesex, U.K.) begins by noting how past British research on flood problems concentrated on refining techniques to implement established policy. In contrast, research covered in North American and Australian publications involved normative issues on policy alternatives and administrative implementation. The workshop's participants included 16 widely recognized scientists, whose origins were about equally divided between Britain and overseas; from this group the workshop's organizers expertly drew ideas for refining British urban riverine flood hazard management and for cultivating links among researchers everywhere. Such intellectual exchange should be of keen interest to flood hazard program managers around the world, to students of comparative institutional performance, to those who make policy on protecting people from hazards, and to hydrologists and other geophysicists who must communicate descriptive information for bureaucratic, political, and public decision- making.

Identities in the third space? Solidity, elasticity and resilience amongst young British Pakistani Muslims.

PubMed

Mythen, Gabe

2012-09-01

Over the last decade the issue of identity has been prevalent in discussions about British Muslims, with the events of 9/11 serving as a touchstone for media debates about religious, national and cultural affiliations. The 7/7 terrorist attacks in the UK led to young British Pakistanis being subjected to intense public and institutional scrutiny and wider political concerns being expressed about the failure of multiculturalism. Young British Pakistanis have thus had to negotiate and maintain their identities in an environment in which they have been defined as a threat to national security whilst simultaneously being pressurized to align with 'core British values'. Within this context, we convey the findings of a qualitative study involving British Pakistanis living in the North-west of England. In presenting the experiences and perspectives of participants, three interconnected processes salient to the maintenance of identity are delineated: solidity, elasticity and resilience. Having unpacked these processes, we draw upon Bhabha's third space thesis to explore the political potentiality of and the limits to hybridic identities. © London School of Economics and Political Science 2012.

A health economist on medical sociology: reflections by an unreconstructed reductionist.

PubMed

Culyer, A J

1985-01-01

Eleven papers in medical sociology, recommended as representative by the Medical Sociology Group of the British Sociology Association, are evaluated by a health economist using five criteria: appeal of intellectual content, insights into political philosophy, explanatory power, predictive power and opportunities for social improvements. The paper concludes that the medical sociology literature is quite weak when judged by these criteria, though stronger on some than others. Sociologists often seem to confuse issues that involve value judgements with ones that do not, and generally seem to display a disconcerting obsession with methodological issues of the most fundamental kind that has inhibited medical sociology from developing interesting analyses of many issues on which, in principle, it ought to have much to offer.

Exposure to smoking in movies among British adolescents 2001–2006

Anderson, Stacey J; Millett, Christopher; Polansky, Jonathan R

2010-01-01

Objective To estimate youth exposure to smoking in movies in the UK and compare the likely effect with the USA. Methods We collected tobacco occurrences data for 572 top-grossing films in the UK screened from 2001 to 2006 and estimated the number of on-screen tobacco impressions delivered to British youths in this time period. Results 91% of films in our sample that contained smoking were youth-rated films (British Board of Film Classification rating ‘15’ and lower), delivering at least 1.10 billion tobacco impressions to British youths during theatrical release. British youths were exposed to 28% more smoking impressions in UK youth-rated movies than American youth-rated movies, because 79% of movies rated for adults in the USA (‘R’) are classified as suitable for youths in the UK (‘15’ or ‘12A’). Conclusion Because there is a dose-response relation between the amount of on-screen exposure to smoking and the likelihood that adolescents will begin smoking, the fact that there is substantially higher exposure to smoking in youth-rated films in the UK than in the USA suggests that the fraction of all youth smoking because of films in the UK is probably larger than in the USA. Other countries with ratings systems that are less conservative (in terms of language and sexuality) than the USA will also be likely to deliver more on-screen tobacco impressions to youths. Assigning an ‘18’ classification to movies that contain smoking would substantially reduce youth exposure to on-screen smoking and, hence, smoking initiation among British youths. PMID:20197360

The infantry accounts for more than a quarter of the British Army but there is a lack of data about the social and educational background of its recruits. To provide an insight into British Army infantry recruits' personal, social and educational background prior to enlistment. The study sample consisted of infantry recruits who enlisted into the British Army School of Infantry. Each recruit completed a 95-item biographical questionnaire. Descriptive statistics were used to describe the sample in terms of demographic, physical, personal, social and educational attributes. The study sample consisted of 1000 male recruits. Over half of the recruits were consuming alcohol at a hazardous or harmful level prior to enlistment and 60% of recruits had used cannabis prior to joining the Army. Academic attainment was low, with the majority of recruits achieving GCSE grade C and below in most subjects, with 15% not taking any examinations. Over half the recruits had been in trouble with the police and either been suspended or expelled from school. Substance misuse and poor behaviour are highly prevalent among recruits prior to enlistment. Taken alongside existing evidence that some of these problems are commonplace among personnel in regular service, the assumption that the British Army infantry is, in itself, a cause of these behaviours should be questioned. © The Author 2015.

Cluster randomised trials in the medical literature: two bibliometric surveys

PubMed Central

Bland, J Martin

2004-01-01

Background Several reviews of published cluster randomised trials have reported that about half did not take clustering into account in the analysis, which was thus incorrect and potentially misleading. In this paper I ask whether cluster randomised trials are increasing in both number and quality of reporting. Methods Computer search for papers on cluster randomised trials since 1980, hand search of trial reports published in selected volumes of the British Medical Journal over 20 years. Results There has been a large increase in the numbers of methodological papers and of trial reports using the term 'cluster random' in recent years, with about equal numbers of each type of paper. The British Medical Journal contained more such reports than any other journal. In this journal there was a corresponding increase over time in the number of trials where subjects were randomised in clusters. In 2003 all reports showed awareness of the need to allow for clustering in the analysis. In 1993 and before clustering was ignored in most such trials. Conclusion Cluster trials are becoming more frequent and reporting is of higher quality. Perhaps statistician pressure works. PMID:15310402

This prospective British Ophthalmological Surveillance Unit (BOSU) study on dysthyroid optic neuropathy (DON) determines the incidence, presenting features and management throughout the UK. New cases were identified through the BOSU yellow card and an initial questionnaire and a subsequent 9-month follow-up questionnaire were posted out. From August 2015 to August 2016 DON was reported in 49 patients with 71 eyes affected, 22 patients had bilateral DON. The most common presenting symptom was blurred vision (83%) and the most common examination finding was upgaze restriction (85%). 85% of patients were initially treated with 3 days of either 1 g or 500 mg intravenous methyl prednisolone. We received 25 follow-up questionnaires (51% of the initial cohort) with 38 eyes treated for DON and 13 bilateral cases. The average steroid dose over 9 months was 4.5 g and 47% of patients had a surgical orbital decompression. The mean visual acuity gain after 9 months of follow-up for all patients was 0.25 LogMAR. The mean visual acuity gain after just medical therapy was 0.25 LogMAR and after both medical therapy and orbital decompression it was 0.24 LogMAR. In conclusion, the incidence of DON in the UK from this study is 0.75 per million population per annum. The majority of patients are treated with initial medical therapy and almost half of all patients subsequently went on to have an orbital decompression. With either medical therapy or medical and surgical therapy, vision can improve in patients with DON.

Dead-blow hammer design applied to a calibration target mechanism to dampen excessive rebound

NASA Technical Reports Server (NTRS)

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.

In defence of utility: the medical humanities and medical education.

PubMed

Blease, Charlotte

2016-06-01

The idea that a study of the humanities helps to humanise doctors has become a leitmotif within the field. It is argued that the humanities (especially, literature) help to foster insights beyond those provided by biomedical training. Healthy young medics, it is claimed, can thereby gain significant insights into patienthood, and obtain important skills that may be valuable for their professional life. But the instrumentality of the humanities is not the only justification proffered for its inclusion in medical curricula. In this paper I critically examine the two overarching justifications recurrently cited in the mainstream literature-namely, (1) the instrumental worth and (2) the intrinsic value of the medical humanities in educating doctors. Examining these theses (and focusing on the views of a leading medical humanities scholar) I show that the bifurcation into instrumental versus non-instrumental justifications is not supported by the argumentation. Instead, I find that the particulars of the supposedly intrinsic justifications amount to an unambiguously instrumental defence of the humanities. Contextualizing the present investigation to probe further, I describe a long history of debate about the role of the humanities in British education and find that it rests on unsupported dichotomies (utility vs non-utility, theoretical vs applied, educated vs trained). I conclude that the medical humanities' manifesto would be more intellectually honest and coherent, and provide a more robust defence of its value in medical education, if it chose to embrace a wholly instrumental rationale for its role.

‘They Shall See His Face’: Blindness in British India, 1850–1950

PubMed Central

Nair, Aparna

2017-01-01

This paper explores the social, medical, institutional and enumerative histories of blindness in British India from 1850 to 1950. It begins by tracing the contours and causes of blindness using census records, and then outlines how colonial physicians and observers ascribed both infectious aetiologies and social pathologies to blindness. Blindness was often interpreted as the inevitable consequence of South Asian ignorance, superstition and backwardness.

Predisposing factors leading to depression in the British Army.

PubMed

Finnegan, Alan; Finnegan, Sara; McGee, Paula; Srinivasan, Mike; Simpson, Robin

Few studies have explored the predisposing factors leading to depression within the British Army, and this qualitative investigation provides a novel approach to advance knowledge in this poorly researched area. Information was provided by army mental health (MH) clinicians, with results aligned to theoretical groupings under the headings of: occupational stressors; macho culture, stigma and bullying; unhappy young soldier; relationships and gender. These issues were influenced by peacetime and operational settings; the support offered by the Army Medical Services and unit command. The results indicate that Army personnel are exposed to multi-factorial stressors that are incremental/accumulative in nature. Soldiers can cope with extreme pressures, often in hostile environments, but often cannot cope with a failing relationship. Officers were worried about the occupational implications of reporting ill, and the negative impact on their career, and might seek support from private civilian agencies, which have potentially dangerous ramifications as they may still deploy. GPs refer female soldiers more frequently for a mental health assessment because women express their emotions more openly then men. Young disillusioned soldiers who want to leave the Army form the main group of personnel accessing mental health support, although often they are not clinically depressed.

The pursuit of certainty in diagnosing dementia: cognitive testing, childishness and stress in two British memory clinics.

PubMed

Orr, David M R

2010-12-01

By often taking as its focus the experience of illness in itself, medical anthropology has sometimes neglected the meanings that patients may assign to the diagnostic procedures that they are expected to undergo. This paper puts into anthropological perspective the author's experiences working as an assistant psychologist in two British memory clinics for the detection and treatment of dementia, using comments by patients to illustrate the significance that one aspect of these procedures--cognitive testing--had for them. These comments suggest that the meanings that patients construct with regard to such testing are complex and cannot be understood if one persists in seeing it as a neutral diagnostic tool without broader implications. It is argued that a strong association made by many patients between the cognitive tests and their childhood school experiences informs their reactions for better or worse. It is important to acknowledge the implications of this active interpretation of medical procedures if the memory clinic experience is not to become an alienating and infantilising one.

Medicalization, ambivalence and social control: mothers' descriptions of educators and ADD/ADHD.

PubMed

Malacrida, Claudia

2004-01-01

Conrad notes that non-medical personnel often accomplish the routine, everyday work of medicalization. This is particularly so in the case of Attention Deficit (Hyperactivity) Disorder, where teachers, special educators and school psychologists identify, assess and administer medication to 'problematic' children. Drawing on data from interviews with Canadian and British mothers of ADD/ADHD children, this article explores mothers' perceptions of educators' roles in medicalizing children who are different, comparing medicalization in two divergent sites. In Canada, where ADD/ADHD is a highly medicalized phenomenon, and teachers have few alternative forms of social control available to them in classrooms, it appears that educators are prepared to identify problem children and press for medical treatment with remarkable vigor. In Britain, where medicalization remains incomplete, and where teachers and special educators have more stringent alternative forms of social control available to them, educators were often described as gatekeepers who will refuse the label or to administer medication.

Medical education is fast becoming a separate focus, and together with their clinical commitments, many clinicians now seek higher qualifications and professional accreditation in the field. Research is also developing, and there is a need for evidence-based practice in education, just as in clinical work. This review gives an overview of research into medical education, and explains the fundamentals of educational theory and the specific considerations for the quantitative and qualitative research methods that pertain to it. It also explains the application of these methods to two growing areas of research: technology-enhanced learning (TEL) and normative ethics in training.

MacPhee, Maura; Bouthillette, France

2008-01-01

The British Columbia Nursing Administrative Leadership Institute for First Line Nurse Leaders (BC NLI) is a collaborative partnership among British Columbia's Chief Nursing Officers, the Ministry of Health Nursing Directorate and the University of British Columbia School of Nursing. This initiative consists of a four-day residential program and a year-long leadership project between BC NLI participants and their organizational mentors. The evidence-based curriculum covers universal leadership and management concepts, but it also addresses leadership issues of relevance to nurse leaders in today's complex healthcare environments. The BC NLI is part of a provincial health human resources endeavour to ensure sufficient nursing leaders - for now and in the future. This paper will discuss the development, implementation and evaluation of the BC NLI. Unique aspects of the program, such as its online networking component, will be described, and its role in nursing leadership research will be briefly examined.

The Emerging British Verticillium longisporum Population Consists of Aggressive Brassica Pathogens.

PubMed

Depotter, Jasper R L; Rodriguez-Moreno, Luis; Thomma, Bart P H J; Wood, Thomas A

2017-11-01

Verticillium longisporum is an economically important fungal pathogen of brassicaceous crops that originated from at least three hybridization events between different Verticillium spp., leading to the hybrid lineages A1/D1, A1/D2, and A1/D3. Isolates of lineage A1/D1 generally cause stem striping on oilseed rape (Brassica napus), which has recently been reported for the first time to occur in the United Kingdom. Intriguingly, the emerging U.K. population is distinct from the north-central European stem striping population. Little is known about the pathogenicity of the newly emerged U.K. population; hence, pathogenicity tests were executed to compare British isolates to previously characterized reference strains. In addition to the model plant Arabidopsis thaliana, the pathogenicity of four British isolates was assessed on four cultivars of three Brassica crop species: oilseed rape (Quartz and Incentive), cauliflower (Clapton), and Chinese cabbage (Hilton). To this end, vascular discoloration of the roots, plant biomass accumulations, and fungal stem colonization upon isolate infection were evaluated. The British isolates appeared to be remarkably aggressive, because plant biomass was significantly affected and severe vascular discoloration was observed. The British isolates were successful stem colonizers and the extent of fungal colonization negatively correlated with plant biomass of cauliflower and Quartz oilseed rape. However, in Quartz, the fungal colonization of A1/D1 isolates was significantly lower than that of the virulent reference isolate from lineage A1/D3, PD589. Moreover, despite levels of stem colonization similar to those of A1/D1 strains, PD589 did not cause significant disease on Incentive. Thus, A1/D1 isolates, including British isolates, are aggressive oilseed rape pathogens despite limited colonization levels in comparison with a virulent A1/D3 isolate.

Public perceptions about climate change mitigation in British Columbia's forest sector

The role of forest management in mitigating climate change is a central concern for the Canadian province of British Columbia. The successful implementation of forest management activities to achieve climate change mitigation in British Columbia will be strongly influenced by public support or opposition. While we now have increasingly clear ideas of the management opportunities associated with forest mitigation and some insight into public support for climate change mitigation in the context of sustainable forest management, very little is known with respect to the levels and basis of public support for potential forest management strategies to mitigate climate change. This paper, by describing the results of a web-based survey, documents levels of public support for the implementation of eight forest carbon mitigation strategies in British Columbia’s forest sector, and examines and quantifies the influence of the factors that shape this support. Overall, respondents ascribed a high level of importance to forest carbon mitigation and supported all of the eight proposed strategies, indicating that the British Columbia public is inclined to consider alternative practices in managing forests and wood products to mitigate climate change. That said, we found differences in levels of support for the mitigation strategies. In general, we found greater levels of support for a rehabilitation strategy (e.g. reforestation of unproductive forest land), and to a lesser extent for conservation strategies (e.g. old growth conservation, reduced harvest) over enhanced forest management strategies (e.g. improved harvesting and silvicultural techniques). We also highlighted multiple variables within the British Columbia population that appear to play a role in predicting levels of support for conservation and/or enhanced forest management strategies, including environmental values, risk perception, trust in groups of actors, prioritized objectives of forest management and socio

BACKGROUND: Sport- and recreation-related injuries are a major source of morbidity in the paediatric population. Long-term trends for these injuries are largely unknown. METHODS: A traumatic injury surveillance system (the Canadian Hospitals Injury Reporting and Prevention Program) was used to examine the demographics and trends of paediatric sports injuries in children who presented to or were directly admitted to the British Columbia Children’s Hospital (Vancouver, British Columbia) emergency department or intensive care unit from 1992 to 2005. RESULTS: Over the 14-year study period, there was a significant increase in sport- and recreation-related injuries among patients who presented to the British Columbia Children’s Hospital. Of 104,414 injuries between 1992 and 2005, 27,466 were related to sports and recreational activities. The number of sport-related injuries increased by 28%, while all-cause injuries did not change significantly. Males comprised 68% of the sport-related injuries, and both sexes displayed an increasing trend over time. Cycling, basketball, soccer and ice hockey were the top four injury-causing activities. The main body parts injured were the face, head and digits. CONCLUSIONS: Paediatric sports injuries significantly increased at the British Columbia Children’s Hospital over the 14-year study period. This is likely due to increased sport participation, increased risk associated with certain sports, or both. Trends in paediatric sports injury may be predicted by changes in popular media, possibly allowing prevention programs to help to avoid these injuries before they occur. PMID:22468125

Do final-year medical students have sufficient prescribing competencies? A systematic literature review.

2018-04-01

Prescribing errors are an important cause of patient safety incidents and are frequently caused by junior doctors. This might be because the prescribing competence of final-year medical students is poor as a result of inadequate clinical pharmacology and therapeutic (CPT) education. We reviewed the literature to investigate which prescribing competencies medical students should have acquired in order to prescribe safely and effectively, and whether these have been attained by the time they graduate. PubMed, EMBASE and ERIC databases were searched from the earliest dates up to and including January 2017, using the terms 'prescribing', 'competence' and 'medical students' in combination. Articles describing or evaluating essential prescribing competencies of final-year medical students were included. Twenty-five articles describing, and 47 articles evaluating, the prescribing competencies of final-year students were included. Although there seems to be some agreement, we found no clear consensus among CPT teachers on which prescribing competencies medical students should have when they graduate. Studies showed that students had a general lack of preparedness, self-confidence, knowledge and skills, specifically regarding general and antimicrobial prescribing and pharmacovigilance. However, the results should be interpreted with caution, given the heterogeneity and methodological weaknesses of the included studies. There is considerable evidence that final-year students have insufficient competencies to prescribe safely and effectively, although there is a need for a greater consensus among CPT teachers on the required competencies. Changes in undergraduate CPT education are urgently required in order to improve the prescribing of future doctors. © 2018 VU University Medical Centre.

Patients with acute myocardial infarction (MI) and nonobstructive coronary artery disease (CAD) have an elevated cardiac event rate, suggesting that these patients may benefit from cardiac medication. We evaluated the rates of cardiac medication use 3 months before angiography and 3 months following clinically indicated angiography for MI in patients with no CAD, nonobstructive CAD, and obstructive CAD. We also examined the sex differences in cardiac medication use 3 months following angiography in patients by extent of angiographic CAD. We studied patients ≥20 years old with MI undergoing coronary angiography in British Columbia, Canada, from January 1, 2008, to March 31, 2010 (n = 3,841). No CAD, nonobstructive CAD, and obstructive CAD were defined as 0%, 1% to 49%, and ≥50% luminal narrowing in any epicardial coronary artery, respectively. Medication use, 3 months before and 3 months following angiography, was obtained through British Columbia PharmaNet for angiotensin-converting enzyme inhibitors (ACE-Is), angiotensin receptor blockers (ARBs), calcium channel blockers (CCBs), beta-blockers, statins, and antiplatelet agents. Optimal medical therapy (OMT) was defined as filled prescriptions for all three: ACE-Is/ARBs, beta-blockers, and statins. Following angiography, in all medication categories except CCBs, patients with no CAD and nonobstructive CAD had significantly lower rates of prescriptions filled than patients with obstructive CAD (all p < 0.001). After adjusting for age and prior medication use, patients with nonobstructive CAD were still less likely to receive these medications than patients with obstructive CAD, including OMT with an odds ratio = 0.25 (95% confidence interval: 0.18-0.36). There were no significant sex differences in medication use 3 months postangiography. In post-MI patients, medication use following angiography is significantly lower in nonobstructive CAD than obstructive CAD at 3 months. While sex was not an

Medical school applicants from ethnic minority groups: identifying if and when they are disadvantaged.

PubMed Central

McManus, I. C.; Richards, P.; Winder, B. C.; Sproston, K. A.; Styles, V.

1995-01-01

OBJECTIVE--To assess whether people from ethnic minority groups are less likely to be accepted at British medical schools, and to explore the mechanisms of disadvantage. DESIGN--Prospective study of a national cohort of medical school applicants. SETTING--All 28 medical schools in the United Kingdom. SUBJECTS--6901 subjects who had applied through the Universities' Central Council on Admissions in 1990 to study medicine. MAIN OUTCOME MEASURES--Offers and acceptance at medical school by ethnic group. RESULTS--Applicants from ethnic minority groups constituted 26.3% of those applying to medical school. They were less likely to be accepted, partly because they were less well qualified and applied later. Nevertheless, taking educational and some other predictors into account, applicants from ethnic minority groups were 1.46 times (95% confidence interval 1.19 to 1.74) less likely to be accepted. Having a European surname predicted acceptance better than ethnic origin itself, implying direct discrimination rather than disadvantage secondary to other possible differences between white and non-white applicants. Applicants from ethnic minority groups fared significantly less well in 12 of the 28 British medical schools. Analysis of the selection process suggests that medical schools make fewer offers to such applicants than to others with equivalent estimated A level grades. CONCLUSIONS--People from ethnic minority groups applying to medical school are disadvantaged, principally because ethnic origin is assessed from a candidate's surname; the disadvantage has diminished since 1986. For subjects applying before A level the mechanism is that less credit is given to referees' estimates of A level grades. Selection would be fairer if (a) application forms were anonymous; (b) forms did not include estimates of A level grades; and (c) selection took place after A level results are known. PMID:7888888

Personality, lifestyles, alcohol and drug consumption in a sample of British medical students.

Ashton, C H; Kamali, F

1995-05-01

Personality characteristics and lifestyle variables were assessed in two cohorts of second-year medical students at the University of Newcastle upon Tyne, UK as part of a psychopharmacology 'teach-in' in 1993 and 1994. The pooled sample included 186 students: 77 men, 109 women, mean age 20.4 +/- 1.8 years. Measures included the Eysenck Personality Questionnaire, the Hospital Anxiety Depression Scale, and a questionnaire concerning consumption of alcohol, tobacco, cannabis and other illicit drugs, and physical exercise. The results were compared, where possible, with a similar survey in Newcastle upon Tyne medical students in 1983 and 1984. Personality variables, prevalence of cigarette smoking, levels of caffeine consumption and participation in sports had not changed significantly over the decade. There appeared to be a modest overall increase in alcohol consumption and in the 1993 and 1994 cohorts of students, 25.5% of those who drank alcohol exceeded recommended low risk levels (comparable data not available for 1983 and 1984). Reported use of cannabis and other illicit drugs had more than doubled, and in the present survey 49.2% of students recorded using cannabis and 22% had tried other illicit drugs. Corresponding figures for 1983 and 1984 were 20.9% for cannabis and 3.3% for other illicit drugs. Anxiety levels were not measured in 1983 and 1984 but in the present survey 39.3% of the students had anxiety ratings within the clinically significant range. The high levels of alcohol consumption and illicit drug use, and the high anxiety ratings, in this sample of medical students are a cause for concern.(ABSTRACT TRUNCATED AT 250 WORDS)

Paying for volume: British Columbia's experiment with funding hospitals based on activity.

PubMed

Sutherland, Jason M; Liu, Guiping; Crump, R Trafford; Law, Michael

2016-11-01

For decades, Canadian hospitals have been funded using global budgets, a lump sum for providing care irrespective of the volume or mix of patients. In 2010, British Columbia (BC) introduced a controversial, but limited, form of activity-based funding (ABF) for hospitals. This study uses a quasi-experimental design to evaluate the impact of the introduction of ABF funding in the province. Our analysis used the population of patient-level acute hospitalization and day surgery discharge summaries from BC's acute hospitals from April 1, 2008 to March 31, 2013. Our outcome measures focused on both the intended and unintended impacts of ABF including the volume of cases, the efficiency of care, and the quality of care delivered. Our analysis used interrupted time series analysis. There was an increase in the volume of inpatient surgical activity associated with the implementation of ABF. The volume of medical cases dropped, and medical patients' lengths of stays increased. There were no changes in measures of quality. Hospitals' measurable responses to ABF policies on a number of key performance measures were mixed. Though BC's experiment with ABF was not associated with increases in hospital volumes for all types of care, the experience provides key lessons that small magnitude and short-term reforms are unlikely to change hospitals' behaviors quickly.

Simmons, Kingsley L; Maekawa, Atsuko; Smith, Jane A

2011-01-01

We compared social and psychological adjustment to surgery ending with an ostomy in British and Japanese patients. In response to a postal survey, 948 ostomy patients (464 British and 484 Japanese), selected at random from respective national databases, provided assessable data on the Ostomy Adjustment Inventory-23 (OAI-23), a validated scale for measurement of psychosocial adjustment to an ostomy. Analysis of variance revealed that country of residence (F1,876 = 50.9, P < .001) and time since surgery (F3,876 = 9.9, P < .001) significantly influenced psychosocial adjustment to an ostomy. British persons with an ostomy experienced higher psychosocial adjustment to an ostomy than did Japanese respondents. Multivariate analysis based on acceptance, social engagement, anxious-preoccupation, and anger also found that country of residence and time since surgery influenced psychosocial adjustment (Pillai's Trace: V = 0.22, F = 67.15, P < 0.001, and V = 0.05, F = 3.6, P ≤ .001, respectively). Acceptance and social engagement (discriminant coefficient = 0.92 and 0.56, respectively) made the largest contribution. Psychosocial functioning differed in British and Japanese persons with an ostomy, suggesting that culture influences psychosocial adjustment to life with an ostomy. These findings support the need for culturally informed ostomy care.

'Recharge my exhausted batteries': Overbeck's Rejuvenator, Patenting, and Public Medical Consumers, 1924-37.

PubMed

Stark, James F

2014-10-01

Although historians have shown that there has been a complex and multi-layered relationship between the body, medicine and the force of electricity, many avenues remain to be explored. One of the most prominent of these is the way in which electrotherapy technologies were marketed to a wide variety of different end users and intermediaries. This paper offers the first historical analysis of one such device - the Overbeck Rejuvenator - a 1920s electrotherapy machine designed for use by the general public. Its inventor, Otto Overbeck, was not a medical man and this enabled him to use aggressive strategies of newspaper advertising, using testimonials to market his product alongside appeals to his own scientific authority. He commissioned the prestigious Ediswan Company to manufacture the Rejuvenator on a large scale, and took out patents in eleven countries to persuade users of the efficacy of the device. In response to Overbeck's activities, the British Medical Association enlisted an electrical engineer to examine the Rejuvenator, contacted practitioners whose endorsements were being used in publicity material, and denied Overbeck permission to advertise in the British Medical Journal. Despite this, the Rejuvenator brought its inventor wealth and notoriety, and helped redefine the concept of 'rejuvenation', even if the professional reception of such a device was almost universally hostile. This paper shows how the marketing, patenting and publishing of Overbeck combined to persuade members of the laity to try the Rejuvenator as an alternative form of therapy, bypassing the medical profession in the process.

Home Oxygen Program review: Regionalization in Vancouver Coastal Health and British Columbia.

PubMed

Sandberg, Dan

2015-01-01

Since its inception in the 1980s, the Home Oxygen Program in British Columbia was centrally managed by the Ministry of Health. Initially a small program with few clients across the province, it soon became a large program with many clients and increasing expenditures. A pilot program started in Victoria (British Columbia) in 1996 demonstrated that managing the program locally could offer better client care, better contract management and significant cost savings. In 2002, the pilot's model and recommendations were implemented in British Columbia's five health authorities. The present review details the experiences of regionalizing the program in the Vancouver Coastal Health authority. After fine adjustments to the model were developed and new contracts and criteria changes made, better care for clients was provided than the previous centralized model at a reduced cost to the taxpayer.

Representatives of BC's health authorities also attend as guests. This paper is based on the 2008-2009 annual report of the GPSC. It summarizes the history and main activities of the GPSC. The GPSC is currently supporting a number of key activities to transform primary care in BC. These activities include the Full Service Family Practice Incentive Program, which provides incentive payments to promote enhanced primary care; the Practice Support Program, which provides family physicians and their medical office assistants with various practical evidence-based strategies and tools for managing practice enhancement; the Family Physicians for BC Program to develop family practices in areas of identified need; the Shared Care Committee, which supports and enables the determination of appropriate scopes of practice among GPs, specialists, and other health care professionals; the Divisions of Family Practice, which are designed to facilitate interactions among family doctors and between doctors and their respective health authorities; and the Community Healthcare and Resource Directory, a Web-based resource to help health care providers find appropriate mental health resources. Early results indicate that the GPSC's initiatives are enhancing the delivery of primary care services in BC.

To compare the incidence of sexually transmitted diseases (STD) in British troops in the tropics with that in a standard population. Retrospective analysis of STD clinic records over one calendar year. A British Military Hospital in the Tropics serving 1441 resident personnel. All patients attending a STD clinic. 815 cases of STD were recorded during the study period, giving incidence rate of 56,558 per 100,000 population per year. When compared with a matched population from England and Wales, the age standardised relative risk for STD amongst tropical troops was 25.0 (95% confidence interval 24.9 to 25.1). Thirty nine percent of cases reported prostitute contact as a source of their disease. Of patients questioned about condom usage, 70% reported that they did not normally use a condom. British troops spending short periods of time in a tropical environment are significantly more likely to acquire a STD than men in the same age groups in England and Wales. The proportions of cases who reported that they did not use condoms and the number who cited prostitute contact as a source of infection indicate that even greater sexual education of troops on deployment overseas may be required.

Although emergency departments (EDs) in Canada's rural areas serve approximately 20% of the population, a serious problem in access to health care services has emerged. The objective of this project was to compare access to support services in rural EDs between British Columbia and Quebec. Rural EDs were identified through the Canadian Healthcare Association's Guide to Canadian Healthcare Facilities. We selected hospitals with 24/7 ED physician coverage and hospitalization beds that were located in rural communities (using the rural and small town definition from Statistics Canada). Data were collected from ministries of health, local health authorities, and ED statistics. A telephone interview was administered to collect denominative user data statistics and determine the status of services. British Columbia has more rural EDs (n  =  34) than Quebec (n  =  26). EDs in Quebec have higher volumes (19,310 versus 7,793 annual visits). With respect to support services, 81% of Quebec rural EDs have a 24/7 on-call general surgeon compared to 12% for British Columbia. Nearly 75% of Quebec rural EDs have 24/7 access to computed tomography versus only 3% for British Columbia. Rural EDs in Quebec are also supported by a greater proportion of intensive care units (88% versus 15%); however, British Columbia appears to have more medevac aircraft/helicopters than Quebec. The results suggest that major differences exist in access to support services in rural EDs in British Columbia and Quebec. A nationwide study is justified to address this issue of variability in rural and remote health service delivery and its impact on interfacility transfers and patient outcomes.

Treatment options and therapeutic guidelines have evolved substantially since highly active antiretroviral treatment (HAART) became the standard of HIV care in 1996. We conducted the present population-based analysis to characterize the determinants of direct costs of HAART over time in British Columbia, Canada. We considered individuals ever receiving HAART in British Columbia from 1996 to 2011. Linear mixed-effects regression models were constructed to determine the effects of demographic indicators, clinical stage, and treatment characteristics on quarterly costs of HAART (in 2010$CDN) among individuals initiating in different temporal periods. The least-square mean values were estimated by CD4 category and over time for each temporal cohort. Longitudinal data on HAART recipients (N = 9601, 17.6% female, mean age at initiation = 40.5) were analyzed. Multiple regression analyses identified demographics, treatment adherence, and pharmacological class to be independently associated with quarterly HAART costs. Higher CD4 cell counts were associated with modestly lower costs among pre-HAART initiators [least-square means (95% confidence interval), CD4 > 500: 4674 (4632-4716); CD4: 350-499: 4765 (4721-4809) CD4: 200-349: 4826 (4780-4871); CD4 <200: 4809 (4759-4859)]; however these differences were not significant among post-2003 HAART initiators. Population-level mean costs increased through 2006 and stabilized post-2003 HAART initiators incurred quarterly costs up to 23% lower than pre-2000 HAART initiators in 2010. Our results highlight the magnitude of the temporal changes in HAART costs, and disparities between recent and pre-HAART initiators. This methodology can improve the precision of economic modeling efforts by using detailed cost functions for annual, population-level medication costs according to the distribution of clients by clinical stage and era of treatment initiation.

Medical student attitudes about mental illness: does medical-school education reduce stigma?

2012-05-01

Reducing stigma associated with mental illness is an important aim of medical education, yet evidence indicates that medical students' attitudes toward patients with mental health problems deteriorate as they progress through medical school. Authors examined medical students' attitudes to mental illness, as compared with attitudes toward other medical illness, and the influence of the number of years spent in medical school, as well as of several key socio-demographic, ethnic, and cultural variables. A group of 760 U.K. medical students completed a nationwide on-line survey examining their attitudes toward patients with five conditions (pneumonia, depression, psychotic symptoms, intravenous drug use, long-standing unexplained abdominal complaints), using the Medical Condition Regard Scale (MCRS). Students were also asked whether they had completed the psychiatry rotation or had personal experience of mental disorders themselves or among their friends or family members. They were also asked about their ethnic group (using U.K. national census categories), religious affiliation, and how important religion was in their lives. Independent-samples t-tests and one-way ANOVA were used to compare differences between groups on the MCRS. Students showed the highest regard for patients with pneumonia and lowest regard for patients with long-standing, unexplained abdominal complaints. Although attitudes toward pneumonia were more positive in fifth-year students than in first-year students, attitudes toward unexplained chronic abdominal pain were worse in fifth-year students than in first-year students. Personal experience of mental health treatment, or that among family and friends, were associated with less stigmatizing attitudes. Men showed more stigmatization than women for nearly all conditions; Chinese and South Asian students showed more stigmatizing attitudes toward delusions and hallucinations than their white British counterparts.

Gamification of Medication Adherence in Epilepsy.

2017-11-01

Adherence to medication regimens is a crucial factor in seizure-freedom and well-being for people with epilepsy. In contrast, taking medication inconsistently increases the risk of not only seizures and their adverse effects, but drug side-effects and unnecessary modifications to treatment plans. Epilepsy is prevalent across all age groups and we have been slow to utilise both the technologies and psychologies derived from computer gaming. Gaming has broken through to the mainstream and is no longer the preserve of younger males, mirroring the adoption of smart-phones. 'Gamification' motivates users into engaging in an activity with a higher intensity and duration. Introducing gaming elements into a non-gaming context has the potential to transform routine tasks into more enjoyable and motivating experiences. This has been exploited by marketing executives, but also has clear uses in a healthcare setting too. We discuss how previously published frameworks could be employed to help people with epilepsy adhere to medication regimens to create a patient-focussed, modifiable and fun experience.

To explore the effects of type 2 diabetes on British-Pakistani women's identity and its relationship with self-management. Type 2 diabetes is more prevalent and has worse outcomes among some ethnic minority groups. This may be due to poorer self-management and an inadequate match of health services to patient needs. The influence that type 2 diabetes has on British-Pakistani women's identity and subsequent self-management has received limited attention. An explorative qualitative study. Face-to-face semi-structured English and Urdu language interviews were conducted with a purposively selected heterogeneous sample of 15 British-Pakistani women with type 2 diabetes. Transcripts were analysed thematically. Four themes emerged: Perceived change in self emphasised how British-Pakistani women underwent a conscious adaptation of identity following diagnosis; Familiarity with ill health reflected women's adjustment to their changed identity over time; Diagnosis improves social support enabled women to accept changes within themselves and Supporting family is a barrier to self-management demonstrated how family roles were an aspect of women's identities that was resilient to change. The over-arching theme Role re-alignment enables successful self-management encapsulated how self-management was a continuous process where achievements needed to be sustained. Inter-generational differences were also noted: first generation women talked about challenges associated with ageing and co-morbidities; second generation women talked about familial and work roles competing with self-management. The complex nature of British-Pakistani women's self-identification requires consideration when planning and delivering healthcare. Culturally competent practice should recognise how generational status influences self-identity and diabetes self-management in ethnically diverse women. Health professionals should remain mindful of effective self-management occurring alongside, and being

In all, 162 British hospice volunteers completed the Inventory of Motivations for Hospice Palliative Care Volunteerism (IMHPCV) of Claxton-Oldfield, Wasylkiw, Mark, and Claxton-Oldfield.(1) The IMHPCV taps into 5 different categories of motives for becoming a hospice palliative care volunteer: altruism, civic responsibility, leisure, self-promotion, and personal gain. Altruistic motives were the most influential reasons for choosing to join hospice; personal gain motives were the least influential reasons for becoming a hospice volunteer. Altruistic motives were found to be a significant predictor of volunteers' length of service to the hospice. Compared to previously collected data from a sample of Canadian hospice palliative care volunteers,(1) the current study's sample of British hospice volunteers scored significantly different on 2 of the 5 categories of motives on the IMHPCV.

The British and curriculum development in West Africa: A historical discourse

THE BRITISH AND CURRICULUM DEVELOPMENT IN WEST AFRICA: A HISTORICAL STUDY - Only recently have African nations begun to make their way towards establishing genuinely autonomous education systems incorporating elements of indigenous culture. The present study examines the historical development of curriculum in British West Africa in its links with the educational activities of the early Christian missionaries and the imposition of British colonial rule. For over 300 years, the curriculum content was essentially European in nature. African interests and cultural practices were largely excluded, as "bookwork" was favored over "handwork". The colonial curriculum also helped introduce a new social order to West Africa, leading to the rise of new local elites reading, writing, and speaking foreign European languages. This study explores how the idea of a "civilized" person, promoted through the colonial school curriculum, developed new local elites with different sets of values and expectations that often made them strangers in their own societies. It also describes the connection between this curriculum and the repeated failure of education-reform efforts.

2010-01-01

In 2009, an expansion of West Nile virus (WNV) into the Canadian province of British Columbia was detected. Two locally acquired cases of infection in humans and 3 cases of infection in horses were detected by ELISA and plaque-reduction neutralization tests. Ten positive mosquito pools were detected by reverse transcription PCR. Most WNV activity in British Columbia in 2009 occurred in the hot and dry southern Okanagan Valley. Virus establishment and amplification in this region was likely facilitated by above average nightly temperatures and a rapid accumulation of degree-days in late summer. Estimated exposure dates for humans and initial detection of WNV-positive mosquitoes occurred concurrently with a late summer increase in Culex tarsalis mosquitoes (which spread western equine encephalitis) in the southern Okanagan Valley. The conditions present during this range expansion suggest that temperature and Cx. tarsalis mosquito abundance may be limiting factors for WNV transmission in this portion of the Pacific Northwest.

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.

Mapreduce is Good Enough? If All You Have is a Hammer, Throw Away Everything That's Not a Nail!

Lin, Jimmy

2013-03-01

Hadoop is currently the large-scale data analysis "hammer" of choice, but there exist classes of algorithms that aren't "nails" in the sense that they are not particularly amenable to the MapReduce programming model. To address this, researchers have proposed MapReduce extensions or alternative programming models in which these algorithms can be elegantly expressed. This article espouses a very different position: that MapReduce is "good enough," and that instead of trying to invent screwdrivers, we should simply get rid of everything that's not a nail. To be more specific, much discussion in the literature surrounds the fact that iterative algorithms are a poor fit for MapReduce. The simple solution is to find alternative, noniterative algorithms that solve the same problem. This article captures my personal experiences as an academic researcher as well as a software engineer in a "real-world" production analytics environment. From this combined perspective, I reflect on the current state and future of "big data" research.

Kitson, Nicole A; Price, Morgan; Bowen, Michael; Lau, Francis

Medication errors are a significant source of actual and potential harm for patients. Community medication records have the potential to reduce medication errors, but they can also introduce unintended consequences when there is low fit to task (low cognitive fit). PharmaNet is a provincially managed electronic repository that contains the records for community-based pharmacy-dispensed medications in British Columbia. This research explores the usability of PharmaNet, as a representative community-based medication repository. We completed usability inspections of PharmaNet through vendor applications. Vendor participants were asked to complete activity-driven scenarios, which highlighted aspects of medication management workflow. Screen recording was later reviewed. Heuristics were applied to explore usability issues and improvement opportunities. Usability inspection was conducted with four PharmaNet applications. Ninety-six usability issues were identified; half of these had potential implications for patient safety. These were primarily related to login and logout procedures; display of patient name; display of medications; update and display of alert information; and the changing or discontinuation of medications. PharmaNet was designed primarily to support medication dispensing and billing activities by community pharmacies, but is also used to support care providers with monitoring and prescribing activities. As such, some of the features do not have a strong fit for other clinical activities. To improve fit, we recommend: having a Current Medications List and Displaying Medication Utilization Charts.

Unintended Medication Discrepancies Associated with Reliance on Prescription Databases for Medication Reconciliation on Admission to a General Medical Ward

2009-01-01

Background: In a recent study, 50% of the patients who were admitted to a hospital’s general medicine ward had at least one error in medication orders at the time of admission related to inaccuracies in the medication history. The use of computerized prescription databases has been suggested as a way to improve medication reconciliation at the time of admission. Objective: To quantify and describe unintended discrepancies between a best possible medication history and medications ordered on admission to the general medicine ward in a hospital with routine access to a provincial outpatient prescription database (British Columbia’s PharmaNet). Methods: This prospective study involved 20 patients who were regularly using at least 4 prescription medications before admission to hospital. The best possible medication history for each patient (based on a review of the medical chart and the PharmaNet record and an interview with the patient) was compared with the physician’s admission orders to identify any discrepancies. The frequency and perceived severity of discrepancies, graded independently by 3 physicians, were compared with observations from a similar study conducted at a hospital where a prescription database was not available. Results: The 20 patients were recruited between September 2005 and January 2006. For 8 patients (40%), information in the PharmaNet database was consistent with the prescription medication list obtained during the best possible medication history at the time of admission. For the other 12 patients, a total of 30 unintended discrepancies were identified, 13 (43%) of which were classified as having potential for moderate or severe harm. The proportion of patients with unintended discrepancies was similar to that for the comparison cohort (60% versus 54%). Although the percentage of discrepancies involving omissions was lower than in the comparison population (37% versus 46%), these results were offset by a higher proportion of

Over the past 10 years, the original partnership of clinician and statistician for the running of clinical research projects, especially clinical trials, has come to be supplemented by the data manager and trial coordinator. Increasing numbers of such personnel are now being employed, covering a wide diversity of work areas, including clinical research, medical audit and the cancer registries. The British Oncology Data Managers Association (BODMA) was founded in 1987 and is now in a good position to review the current status of data management in the UK. It is proposed that a national network of data managers and trial coordinators within specialist trials centres, oncology departments and district general hospitals, with a good training programme, plus a recognised career structure, is the way to make the best use of this key resource. BODMA is addressing many of these issues and aims to improve and maintain the quality of data management. PMID:8080719

2009-02-01

The Pneumoconiosis Field Research (PFR) programme was established in the 1950s, to evaluate effects of coal mining exposures on the health and mortality of British coal workers. Surveys of working miners were carried out at 5-yearly intervals, initially in 24 collieries but later concentrating on 10, collecting detailed work histories and health information for each recruit. Here we report on cause-specific mortality in a cohort of almost 18,000 men from 10 British collieries, followed up for periods up to 47 years, yielding over 516,000 life-years of follow-up. External analyses compared cause-specific death rates in the cohort to those of the population of the regions in which the collieries were situated, using Standardised Mortality Ratios (SMRs). The causes investigated included lung cancer, stomach cancer, non-malignant respiratory disorders and cardiovascular disorders. SMRs showed evidence of an initial healthy worker effect diminishing over time. Several causes, including non-malignant respiratory disease and lung cancer, showed a significant deficit of mortality at the start of the study period with an excess in the latter part of the follow-up period. In these results, effects of working conditions are likely to be confounded with smoking habits. Overall, we believe our results may be generalised to the British coal industry since nationalisation.

We asked British medical schools and teaching hospitals about the training they offer to medical students and hospital doctors in cardiopulmonary resuscitation. The response rate was 96%. Training that is practical and consistent with guidelines is offered to nearly all students and house officers, often by consultants. Training for other junior doctors and consultants is much less common. The organisation of training is haphazard, and many hospitals have no resuscitation training officers. As a result, few doctors receive the frequent retraining needed to maintain competence in managing cardiopulmonary arrest.

The Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) cohort is a census of all identified HIV-positive individuals in the province of British Columbia. It was formed through the linkage of nine provincial treatment, surveillance and administrative databases. This open cohort allows for bidirectional analyses from 1996 onward and is refreshed annually. Extensive data collection for cohort members includes demographic information, detailed clinical and laboratory data, complete prescription drug use including antiretroviral agents, and information on health service utilization encompassing inpatient and outpatient care, addictions treatment and palliative care. This cohort provides an unprecedented opportunity to evaluate, over an extended time period, patterns and determinants of key outcomes including engagement in the cascade of HIV care from diagnosis to treatment to viral suppression as well as monitoring trends in medical costs, health outcomes and other key healthcare delivery indicators at a population level with wide-ranging, high-quality data. The overall purpose of these activities is to enable the development and implementation of strategically targeted interventions to improve access to testing, care and treatment for all HIV-positive individuals living in British Columbia. © The Author 2014; all rights reserved.

"What is this genetics, anyway?" Understandings of genetics, illness causality and inheritance among British Pakistani users of genetic services.

PubMed

Shaw, Alison; Hurst, Jane A

2008-08-01

Misconceptions about basic genetic concepts and inheritance patterns may be widespread in the general population. This paper investigates understandings of genetics, illness causality and inheritance among British Pakistanis referred to a UK genetics clinic. During participant observation of genetics clinic consultations and semi-structured interviews in Urdu or English in respondents' homes, we identified an array of environmental, behavioral and spiritual understandings of the causes of medical and intellectual problems. Misconceptions about the location of genetic information in the body and of genetic mechanisms of inheritance were common, reflected the range of everyday theories observed for White British patients and included the belief that a child receives more genetic material from the father than the mother. Despite some participants' conversational use of genetic terminology, some patients had assimilated genetic information in ways that conflict with genetic theory with potentially serious clinical consequences. Additionally, skepticism of genetic theories of illness reflected a rejection of a dominant discourse of genetic risk that stigmatizes cousin marriages. Patients referred to genetics clinics may not easily surrender their lay or personal theories about the causes of their own or their child's condition and their understandings of genetic risk. Genetic counselors may need to identify, work with and at times challenge patients' understandings of illness causality and inheritance.

Furnham, Adrian; Loganathan, Niroosha; McClelland, Alastair

2010-01-01

A programmatic research effort investigated how lay people weigh information on hypothetical patients when making decisions regarding the allocation of scarce medical resources. This study is partly replicative and partly innovative, and looks particularly at whether overweight patients would be discriminated against in allocating resources. This study aims to determine the importance given to specific patient characteristics when lay participants are asked to allocate scarce medical resources. In all, 156 British adults (82 males, 73 females), aged 19 to 84 years, took part. There were few students. Participants completed a questionnaire requiring them to rank 16 hypothetical patients for access to a kidney dialysis machine.The demographic information presented regarding each hypothetical patient differed on four dimensions: gender, weight, mental health, and religiousness. There were significant main effects for gender, weight, and mental health; females, patients of normal weight, and the mentally well were ranked the highest priority for access to a kidney dialysis machine. Participants discriminated most regarding the weight of hypothetical patients. Different patient characteristics, unrelated to medical prognoses, particularly being overweight, may have an impact on decisions regarding the use of scarce medical resources.

The majority of British medical schools now accept for their shortest courses students who have mathematics at A level in place of the former requirement of biology A level. Only a small fraction of the entry, less than one-fifth, enters this way, in spite of statements by most medical schools that they make no distinction between those with mathematics and those with biology when making conditional offers of places. There is no evidence that those without biology are at a disadvantage in the courses. If the prospects of entry without A level biology were better publicized medical schools would have a wider field of possibly abler entrants, and pupils entering sixth forms could defer for a year a choice between a medical (or dental) career and one involving physical science, engineering, or other mathematics-based university education.

A national audit of practice performance against the key performance indicators in the British Association for Sexual Health and HIV (BASHH) and HIV Medical Foundation for AIDS Sexual Health Standards for the Management of Sexually Transmitted Infections (STIs) was conducted in 2011. Approximately 60% and 8% of level 3 and level 2 services, respectively, participated. Excluding partner notification performance, the five lowest areas of performance for level 3 clinics were the STI/HIV risk assessment, care pathways linking care in level 2 clinics to local level 3 services, HIV test offer to patients with concern about STIs, information governance and receipt of chlamydial test results by clinicians within seven working days (the worst area of performance). The five lowest areas of performance for level 2 clinics were participating in audit, having an audit plan for the management of STIs for 2009-2010, the STI/HIV risk assessment, HIV test offer to patients with concern about STIs and information governance. The results are discussed with regard to the importance of adoption of the standards by commissioners of services because of their relevance to other national quality assurance drivers, and the need for development of a national system of STI management quality assurance measurement and reporting.

Abstract Five species of the grass genus Spartina are invading salt marshes along the Pacific coast of North America, of which three have been documented in British Columbia, Canada, in only the last decade. A taxonomic synopsis of the two native (Spartina gracilis, Spartina pectinata) and five introduced Spartina taxa (Spartina anglica, Spartina alterniflora, Spartina densiflora, Spartina patens, Spartina ×townsendii) in the Pacific Northwest is presented to facilitate their identification, including nomenclature, a new taxonomic key, new descriptions for a subset of taxa, and representative specimens. Spartina ×townsendii is newly reported for the flora of British Columbia. The non-coastal species Spartina pectinata is reported from an urban site in British Columbia, the first confirmed report of the taxon for the province. Lectotypes are newly designated for Spartina anglica C.E. Hubb., Spartina maritima subvar. fallax St.-Yves, and Spartina cynosuroides f. major St.-Yves. PMID:22461730

A Moral Panic? The Problematization of Forced Marriage in British Newspapers.

PubMed

Anitha, Sundari; Gill, Aisha K

2015-09-01

This article examines the British media's construction of forced marriage (FM) as an urgent social problem in a context where other forms of violence against women are not similarly problematized. A detailed analysis of four British newspapers over a 10-year period demonstrates that media reporting of FM constitutes a moral panic in that it is constructed as a cultural problem that threatens Britain's social order rather than as a specific form of violence against women. Thus, the current problematization of FM restricts discursive spaces for policy debates and hinders attempts to respond to this problem as part of broader efforts to tackle violence against women. © The Author(s) 2015.

Work-family life courses and BMI trajectories in three British birth cohorts.

2017-02-01

Combining work and family responsibilities has previously been associated with improved health in mid-life, yet little is known about how these associations change over time (both biographical and historical) and whether this extends to body mass index (BMI) trajectories for British men and women. The purpose of this study was to investigate relationships between work-family life courses and BMI trajectories across adulthood (16-42 years) for men and women in three British birth cohorts. Multiply imputed data from three nationally representative British birth cohorts were used-the MRC National Survey of Health and Development (NSHD; 1946 birth cohort, n=3012), the National Child Development Study (NCDS; 1958 birth cohort, n=9614) and the British Cohort Study (BCS; 1970 birth cohort, n=8140). A typology of work-family life course types was developed using multi-channel sequence analysis, linking annual information on work, partnerships and parenthood from 16 to 42 years. Work-family life courses were related to BMI trajectories using multi-level growth models. Analyses adjusted for indicators of prior health, birthweight, child BMI, educational attainment and socioeconomic position across the life course, and were stratified by gender and cohort. Work-family life courses characterised by earlier transitions to parenthood and weaker long-term links to employment were associated with greater increases in BMI across adulthood. Some of these differences, particularly for work-family groups, which are becoming increasingly non-normative, became more pronounced across cohorts (for example, increases in BMI between 16 and 42 years in long-term homemaking women: NSHD: 4.35 kg m -2 , 95% confidence interval (CI): 3.44, 5.26; NCDS: 5.53 kg m - 2 , 95% CI: 5.18, 5.88; BCS: 6.69 kg m - 2 , 95% CI: 6.36, 7.02). Becoming a parent earlier and weaker long-term ties to employment are associated with greater increases in BMI across adulthood in British men and women.

Ocean Networks Canada (ONC), a not-for-profit initiative by the University of Victoria that operates several cabled ocean observatories, is developing a new generation of ocean observing systems (referred to as Smart Ocean Systems™), involving advanced undersea observation technologies, data networks and analytics. The ONC Tsunami project is a Smart Ocean Systems™ project that addresses the need for a near-field tsunami detection system for the coastal areas of British Columbia. Recent studies indicate that there is a 40-80% probability over the next 50 for a significant tsunami impacting the British Columbia (BC) coast with runups higher than 1.5 m. The NEPTUNE cabled ocean observatory, operated by ONC off of the west coast of British Columbia, could be used to detect near-field tsunami events with existing instrumentation, including seismometers and bottom pressure recorders. As part of this project, new tsunami simulations are underway for the BC coast. Tsunami propagation is being simulated with the FUNWAVE-TVD model, for a suite of new source models representing Cascadia megathrust rupture scenarios. Simulations are performed by one-way coupling in a series of nested model grids (from the source to the BC coast), whose bathymetry was developed based on digital elevation maps (DEMs) of the area, to estimate both tsunami arrival time and coastal runup/inundation for different locations. Besides inundation, maps of additional parameters such as maximum current are being developed, that will aid in tsunami hazard assessment and risk mitigation, as well as developing evacuation plans. We will present initial results of this work for the Port Alberni inlet, in particular Ucluelet, based on new source models developed using the best available data. We will also present a model validation using measurements of the 2011 transpacific Tohoku-oki tsunami recorded in coastal BC by several instruments from various US and Canadian agencies.

Pearson, Marion L; Andres, Lesley

2010-05-12

To determine the factors influencing pharmacy graduates' selection of their first professional job location. A survey was conducted of the 2007 graduating class of the University of British Columbia, examining hometown location, community and workplace factors, personal relationships, financial factors, and leisure activities. Responses were analyzed to determine whether community size or demographic characteristics affected the degree to which each factor influenced the job location decision. The majority of graduates moved from their hometowns to larger communities, mainly to the largest city in British Columbia. Most of those taking jobs in rural and remote communities grew up in or near those communities, and were more influenced by community size and anticipated working conditions, and less influenced by access to cultural and social activities, than their urban counterparts. The admission of students from rural and remote communities is modestly effective in ensuring a supply of pharmacists for these areas.

Web 2.0 technologies for undergraduate and postgraduate medical education: an online survey.

To identify the current familiarity and use of Web 2.0 technologies by medical students and qualified medical practitioners, and to identify the barriers to its use for medical education. A semi-structured online questionnaire survey of 3000 medical students and 3000 qualified medical practitioners (consultants, general practitioners and doctors in training) on the British Medical Association's membership database. All groups had high familiarity, but low use, of podcasts. Ownership of digital media players was higher among medical students. There was high familiarity, but low use, of other Web 2.0 technologies except for high use of instant messaging and social networking by medical students. All groups stated that they were interested in using Web 2.0 technologies for education but there was lack of knowledge and skills in how to use these new technologies. There is an overall high awareness of a range of new Web 2.0 technologies by both medical students and qualified medical practitioners and high interest in its use for medical education. However, the potential of Web 2.0 technologies for undergraduate and postgraduate medical education will only be achieved if there is increased training in how to use this new approach.

A child of the empire: British sociology and colonialism, 1940s-1960s.

PubMed

Steinmetz, George

2013-01-01

British sociology was established as an academic discipline between 1945 and 1965, just as the British Empire was gearing up for a new phase of developmental colonialism backed by the social and other sciences. Many parts of the emerging sociological discipline became entangled with colonialism. Key themes and methods in sociology and the staff of sociology departments emerged from this colonial context. Historians have tended to place postwar British sociology in the context of expanding higher education and the welfare state, and have overlooked this colonial constellation. The article reconstructs this forgotten moment of disciplinary founding and explores three of the factors that promoted colonial sociology: the Colonial Social Science Research Council, the so-called Asquith universities, and the social research institutes in the colonies; and the involvement of sociologists from the London School of Economics in training colonial officials. © 2013 Wiley Periodicals, Inc.

Explanatory models of psychosis amongst British South Asians.

A strong interest in the understanding, exploring, and extracting explanatory models of psychosis has recently arisen. Explanatory models (EMs) offer justifications and propose explanations when coping with and treating illnesses. Therefore, they may be important predictors of clinical outcome. Explanatory models of psychosis have been explored in many non-Western countries. However, very little research has examined EMs of psychosis in the UK. We therefore, aimed to elicit and describe explanatory models of psychosis amongst British South Asians, using both quantitative and qualitative methods. EMs of psychosis were examined using the Short Explanatory Model Interview (SEMI) in a cross-sectional sample of 45 patients. Most patients (55.5%) attributed their illness to supernatural causes. Few patients cited a biological (4.4%) cause. Majority of patients held dual EMs of psychosis (77.7%), combining prescribed medication and seeing a traditional healer as a treatment method. Duration of Untreated Psychosis (DUP) was not significantly associated with EMs of psychosis. The results suggest that patients hold multi-explanatory models in order to make sense of their illness and these stem from deep rooted traditional beliefs. This highlights the importance of educational intervention, culturally adapted psychological interventions and possibly working together with traditional healers in the UK to provide a positive support system. Further work is required in order to fully understand the relationship between EMs of psychosis and DUP. Copyright © 2015 Elsevier B.V. All rights reserved.

Objectives To explore how representatives from organisations with responsibility for doctors in training perceive risks to the educational progression of UK medical graduates from black and minority ethnic groups (BME UKGs), and graduates of non-UK medical schools (international medical graduates (IMGs)). To identify the barriers to and facilitators of change. Design Qualitative semistructured individual and group interview study. Setting Postgraduate medical education in the UK. Participants Individuals with roles in examinations and/or curriculum design from UK medical Royal Colleges. Employees of NHS Employers. Results Representatives from 11 medical Royal Colleges (n=29) and NHS Employers (n=2) took part (55% medically qualified, 61% male, 71% white British/Irish, 23% Asian/Asian British, 6% missing ethnicity). Risks were perceived as significant, although more so for IMGs than for BME UKGs. Participants based significance ratings on evidence obtained largely through personal experience. A lack of evidence led to downgrading of significance. Participants were pessimistic about effecting change, two main barriers being sensitivities around race and the isolation of interventions. Participants felt that organisations should acknowledge problems, but felt concerned about being transparent without a solution; and talking about race with trainees was felt to be difficult. Participants mentioned 63 schemes aiming to address differential attainment, but these were typically local or specialty-specific, were not aimed at BME UKGs and were largely unevaluated. Participants felt that national change was needed, but only felt empowered to effect change locally or within their specialty. Conclusions Representatives from organisations responsible for training doctors perceived the risks faced by BME UKGs and IMGs as significant but difficult to change. Strategies to help organisations address these risks include: increased openness to discussing race (including ethnic

Drug metabolism and pharmacogenetics: the British contribution to fields of international significance

PubMed Central

Caldwell, John

2006-01-01

The branch of pharmacology we now call ‘drug metabolism', the consideration of the enzymes and procesess determining the disposition of drugs in the body, emerged in the 1840s on the continent of Europe, but British science made little or no contribution until the 1920s. From this point on, the development of the field through the 20th century was shaped to a very significant extent by a series of influential British workers, whose contributions were of global significance and who can now be seen as fathers of the subject. Since the 1950s, and gaining pace inexorably from the 1970s, the significance of drug metabolism to human therapeutics has been greatly added to by the emergence of pharmacogenetics, clinically important hereditary variation in response to drugs, which underpins the current emphasis on personalised medicine. This review examines the British contributions to both these fields through the lives of seven key contributors and attempts to place their work both in the context of its time and its lasting influence.

Energetic cost of standard activities in Gurkha and British soldiers.

Strickland, S S; Ulijaszek, S J

1990-01-01

Measurements of basal metabolic rate and energy expenditure at lying, sitting, standing, and performing a step test at four levels of exercise, were made on Gurkha soldiers stationed in Britain and on British controls matched by body weight and occupational background. There was no significant difference in basal metabolic rate (BMR), nor in the energy cost of lying, sitting and standing between the two groups. Gurhas showed significantly lower gross and net energy expenditure, and so significantly greater net mechanical efficiency, at the lower levels of step exercise. The ratio of gross energy expenditure to BMR was lower in Gurkhas at the lowest rates of stepping compared with the British controls. These results suggest that the energy cost of some physical activities expressed as multiples of BMR may not be constant across populations.

This report contains the results of tests made in the National Advisory Committee for Aeronautics variable density wind tunnel on three airplane models supplied by the British Aeronautical Research Committee. These models, the BE-2E with R.A.F. 19 wings, the British Fighter with R.A.F. 15 wings, and the Bristol Fighter with R.A.F. 30 wings, were tested over a wide range in Reynolds numbers in order to supply data desired by the Aeronautical Research Committee for scale effect studies. The maximum lifts obtained in these tests are in excellent agreement with the published results of British tests, both model and full scale. No attempt is made to compare drag data, owing to the emission of tail surfaces, radiator, etc., from the model, but is shown that the scale effect observed on the drag coefficients in these tests is due to a large extent to the parts of the models other than the wings.

Caribbean and black African men reporting being sexually competent at sexual debut were lower (32·9% for black Caribbean and 21·9% for black African vs 47·4% for white British) and the number of partners in the past 5 years was greater (median 2 [IQR 1-4] for black Caribbean and 2 [1-5] for black African vs 1 [1-2] for white British), and although black Caribbean and black African men reported greater proportions of concurrent partnerships (26·5% for black Caribbean and 38·9% for black African vs 14·8% for white British), these differences were not significant after adjusting for age. Compared with white British women, the proportions of black African and mixed ethnicity women reporting being sexually competent were lower (18·0% for black African and 35·3% for mixed ethnicity vs 47·9% for white British), and mixed ethnicity women reported larger numbers of partners in the past 5 years (median 1 [IQR 1-4] vs 1 [1-2]) and greater concurrency (14·3% vs 8·0%). Reporting STI diagnoses was higher in black Caribbean men (8·7%) and mixed ethnicity women (6·7%) than white British participants (3·6% in men and 3·2% in women). Use of emergency contraception was most commonly reported among black Caribbean women (30·7%). Low sexual function was most common among women of white other ethnicity (30·1%). Adjustment for explanatory factors only partly explained inequalities among some ethnic groups relative to white British ethnicity but did not eliminate ethnic differences in these markers. Ethnic inequalities in sexual health markers exist, and they were not fully explained by differences in their broader determinants. Holistic interventions addressing modifiable risk factors and targeting ethnic groups at risk of poor sexual health are needed.

To examine whether there are significant cross-cultural differences in oral health-related quality of life and perceived treatment need between older people of similar clinical oral status living in Greece and Britain. Cross-sectional surveys of adults living independently aged 65 years or older. In Britain, data from the national diet and nutrition survey were used, while the Greek sample was drawn from two municipalities in Athens. Participants 753 in Britain and 681 in Greece. Oral health-related quality of life, assessed through the modified Oral Impacts on Daily Performance (OIDP) indicator, and perceived need for dental treatment. Thirty-nine per cent of Greek and 12.3% of British dentate and 47.6% of Greek and 16.3% of British edentulous participants had experienced oral impacts affecting their daily life in the last six months. The most prevalent impact was difficulty eating. Apart from that, 56.3% of Greek and 37.1% of British dentate and 33.5% of Greek and 25.3% of British edentulous participants perceived dental treatment need. After controlling for sociodemographic variables, perceived general health and clinical oral status, Greek dentate and edentulous participants were significantly more likely to experience oral impacts than their British counterparts, while in relation to perceived treatment need significant cross-cultural differences existed only between dentate respondents. The results indicated an independent cultural influence in the perception of oral impacts in older people.

Objectives Determine the prevalence of drug use in injured drivers and identify associated demographic factors and crash characteristics. Design Prospective cross-sectional study. Setting Seven trauma centres in British Columbia, Canada (2010–2012). Participants Automobile drivers who had blood obtained within 6 h of a crash. Main outcome measures We analysed blood for cannabis, alcohol and other impairing drugs using liquid chromatography/mass spectrometry (LCMS). Results 1097 drivers met inclusion criteria. 60% were aged 20–50 years, 63.2% were male and 29.0% were admitted to hospital. We found alcohol in 17.8% (15.6% to 20.1%) of drivers. Cannabis was the second most common recreational drug: cannabis metabolites were present in 12.6% (10.7% to 14.7%) of drivers and we detected Δ-9-tetrahydrocannabinol (Δ-9-THC) in 7.3% (5.9% to 9.0%), indicating recent use. Males and drivers aged under 30 years were most likely to use cannabis. We detected cocaine in 2.8% (2.0% to 4.0%) of drivers and amphetamines in 1.2% (0.7% to 2.0%). We also found medications including benzodiazepines (4.0% (2.9% to 5.3%)), antidepressants (6.5% (5.2% to 8.1%)) and diphenhydramine (4.7% (3.5% to 6.2%)). Drivers aged over 50 years and those requiring hospital admission were most likely to have used medications. Overall, 40.1% (37.2% to 43.0%) of drivers tested positive for alcohol or at least one impairing drug and 12.7% (10.7% to 14.7%) tested positive for more than one substance. Conclusions Alcohol, cannabis and a broad range of other impairing drugs are commonly detected in injured drivers. Alcohol is well known to cause crashes, but further research is needed to determine the impact of other drug use, including drug–alcohol and drug–drug combinations, on crash risk. In particular, more work is needed to understand the role of medications in causing crashes to guide driver education programmes and improve public safety. PMID:26966054

The aim of this study was to determine the accuracy of the Grandway MD2301 digital automatic blood pressure monitor by the British Hypertension Society (BHS) and the Association for the Advancement of Medical Instrumentation (AAMI)/the International Organization for Standardization (ISO) protocols. A total of 85 participants were included for evaluation based on the requirements of the BHS and the AAMI/ISO protocols. The validation procedure and data analysis followed the protocols precisely. The device achieved A/A grading for the BHS protocol and maintained A/A grading throughout the low, medium and high blood pressure ranges. The device also fulfilled the requirement of the AAMI/ISO protocol with device-observer differences of -0.9±5.6 and 0.8±5.2 mmHg for systolic and diastolic blood pressure, respectively, for criterion 1, and -0.9±4.7 and 0.8±4.2 mmHg, respectively, for criterion 2. The Grandway MD2301 digital automatic blood pressure monitor achieved A/A grade of the BHS protocol and passed the requirements of the AAMI/ISO protocol in adults.

This study reviewed the news media coverage of statins, seeking to identify specific trends or differences in viewpoint between media outlets and examine common themes. The study is a content analysis of the frequency and content of the reporting of statins in a selection of the British newsprint media. It involved an assessment of the number, timing and thematic content of articles followed by a discourse analysis examining the underlying narratives. The sample was the output of four UK newspapers, covering a broad-spectrum readership, over a six month timeframe 1 October 2013 to 31 March 2014. A total of 67 articles included reference to statins. The majority (39, 58%) were reporting or responding to publication of a clinical study. The ratio of negative to positive coverage was greater than 2:1 overall. In the more politically right-leaning newspapers, 67% of coverage was predominantly negative (30/45 articles); 32% in the more left-leaning papers (7/22 articles). Common themes were the perceived 'medicalisation' of the population; the balance between lifestyle modification and medical treatments in the primary prevention of heart disease; side effects and effectiveness of statins; pharmaceutical sponsorship and implications for the reliability of evidence; trust between the public and government, institutions, research organisations and the medical profession. Newsprint media coverage of statins was substantially influenced by the publication of national guidance and by coverage in the medical journals of clinical studies and comment. Statins received a predominantly negative portrayal, notably in the more right-leaning press. There were shared themes: concern about the balance between medication and lifestyle change in the primary prevention of heart disease; the adverse effects of treatment; and a questioning of the reliability of evidence from research institutions, scientists and clinicians in the light of their potential allegiances and funding. © Article

Objectives Medical tourism involves patients’ intentional travel to privately obtain medical care in another country. Empirical evidence regarding health and safety risks facing medical tourists is limited. Consideration of this issue is dominated by speculation and lacks meaningful input from people with specific expertise in patient health and safety. We consulted with patient health and safety experts in the Canadian province of British Columbia to explore their views concerning risks that medical tourists may be exposed to. Herein, we report on the findings, linking them to existing ethical and legal issues associated with medical tourism. Design We held a focus group in September 2011 in Vancouver, British Columbia with professionals representing different domains of patient health and safety expertise. The focus group was transcribed verbatim and analysed thematically. Participants Seven professionals representing the domains of tissue banking, blood safety, health records, organ transplantation, dental care, clinical ethics and infection control participated. Results Five dominant health and safety risks for outbound medical tourists were identified by participants: (1) complications; (2) specific concerns regarding organ transplantation; (3) transmission of antibiotic-resistant organisms; (4) (dis)continuity of medical documentation and (5) (un)informed decision-making. Conclusions Concern was expressed that medical tourism might have unintended and undesired effects upon patients’ home healthcare systems. The individual choices of medical tourists could have significant public consequences if healthcare facilities in their home countries must expend resources treating postoperative complications. Participants also expressed concern that medical tourists returning home with infections, particularly antibiotic-resistant infections, could place others at risk of exposure to infections that are refractory to standard treatment regimens and thereby pose
