This document is a report of the Light Duty Utility Arm (LDUA) drawing walkdown. The purpose of this walkdown was to validate the essential configuration of the LDUA in preparation of deploying the equipment in a Hanford waste tank. The LDUA system has, over the course of its development, caused the generation of a considerable number of design drawings. The number of drawings is estimated to be well over 1,000. A large number consist of vendor type drawings, furnished by both Pacific Northwest National Laboratory (PNNL) and SPAR Aerospace Limited (SPAR). A smaller number, approximately 200, are H-6 type drawing sheets in the Project Hanford Management Contract (PHMC) document control system. A preliminary inspection of the drawings showed that the physical configuration of the LDUA did not match the documented configuration. As a result of these findings, a scoping walkdown of 20 critical drawing sheets was performed to determine if a problem existed in configuration management of the LDUA system. The results of this activity showed that 18 of the 20 drawing sheets were found to contain errors or omissions of varying concern. Given this, Characterization Engineering determined that a walkdown of the drawings necessary and sufficient to enable safe operation and maintenance of the LDUA should be performed. A review team was assembled to perform a review of all of the drawings and determine the set which would need to be verified through an engineering walkdown. The team determined that approximately 150 H-6 type drawing sheets would need to be verified, 12 SPAR/PNNL drawing sheets would need to be verified and converted to H-6 drawings, and three to six new drawings would be created (see Appendix A). This report documents the results of that walkdown.

The Light Duty Utility Arm (LDUA) was successfully deployed in Tank WM-188 during February and March of 1999 at the Idaho Nuclear Technology and Engineering Center (INTEC) tank farm at the Idaho National Engineering and Environmental Laboratory. Some equipment problems were identified, but most were indicative of any first time activity. Deployment during cold weather imposed additional equipment risks, but in general, equipment response to the winter conditions was better than expected. Three end effectors were demonstrated during the deployment. All performed as expected, although the limited resolution of the Alternating Current Field Measurement end effector cannot absolutely confirm tank integrity, which is necessary for future tank inspections. Four heel samples were taken with the sampler end effector and a broad spectrum of analyses were performed. A detailed inspection of the tank interior was performed with the High Resolution Stereo Video System end effector. The sample information is proving invaluable to the development of new treatment flowsheets and waste forms. It is expected that the LDUA will be deployed for tank inspections through the next several years to support other Notice of Non-Compliance (NON) Consent Order requirements and several other ongoing initiatives.

This report describes the usability testing that has been done for the control and data acquisition system for the Light Duty Utility Arm (LDUA) System. A program of usability testing has been established as a part of a process for making the LDUA as easy to use as possible. The LDUA System is being designed to deploy a family of tools, called End Effectors, into underground storage tanks by means of a robotic arm on the end of a telescoping mast, and to collect and manage the data that they generate. The LDUA System uses a vertical positioning mast, to lower the arm into a tank through an existing 30.5 cm access riser. A Mobile Deployment Subsystem is used to position the mast and arm over a tank riser for deployment, and to transport them from tank to tank. The LDUA System has many ancillary subsystems including the Operations Control Trailer, the Tank Riser Interface and Confinement Subsystem, the Decontamination Subsystem, and the End Effector Exchange Subsystem. This work resulted in the identification of several important improvements to the LDUA control and data acquisition system before the design was frozen. The most important of these were color coding of joints in motion, simultaneous operator control of multiple joints, and changes to the field-of-views of the camera lenses for the robot and other camera systems

Light Duty Utility Arm System applications for tank waste remediation

International Nuclear Information System (INIS)

Carteret, B.A.

1994-10-01

The Light Duty Utility Arm (LDUA) System is being developed by the US Department of Energy's (DOE's) Office of Technology Development (OTD, EM-50) to obtain information about the conditions and contents of the DOE's underground storage tanks. Many of these tanks are deteriorating and contain hazardous, radioactive waste generated over the past 50 years as a result of defense materials production at a member of DOE sites. Stabilization and remediation of these waste tanks is a high priority for the DOE's environmental restoration program. The LDUA System will provide the capability to obtain vital data needed to develop safe and cost-effective tank remediation plans, to respond to ongoing questions about tank integrity and leakage, and to quickly investigate tank events that raise safety concerns. In-tank demonstrations of the LDUA System are planned for three DOE sites in 1996 and 1997: Hanford, Idaho National Engineering Laboratory (INEL), and Oak Ridge National Laboratory (ORNL). This paper provides a general description of the system design and discusses a number of planned applications of this technology to support the DOE's environmental restoration program, as well as potential applications in other areas. Supporting papers by other authors provide additional in-depth technical information on specific areas of the system design

The Modified Light Duty Utility Arm (MLDUA) is a selectable seven or eight degree-of-freedom robot arm with a 16.5 ft (5.03 m) reach and a payload capacity of 200 lb. (90.72 kg). The utility arm is controlled in either joystick-based telerobotic mode or auto sequence robotics mode. The MLDUA deployment system deploys the utility arm vertically into underground radioactive waste storage tanks located at Oak Ridge National Laboratory. These tanks are constructed of gunite material and consist of two 25 ft (7.62 m) diameter tanks in the North Tank Farm and six 50 ft (15.24 m) diameter tanks in the South Tank Farm. After deployment inside a tank, the utility arm reaches and grasps the confined sluicing end effecter (CSEE) which is attached to the hose management arm (HMA). The utility arm positions the CSEE within the tank to allow the HMA to sluice the tank's liquid and solid waste from the tank. The MLDUA is used to deploy the characterization end effecter (CEE) and gunite scarifying end effecter (GSEE) into the tank. The CEE is used to survey the tank wall's radiation levels and the physical condition of the walls. The GSEE is used to scarify the tank walls with high-pressure water to remove the wall scale buildup and a thin layer of gunite which reduces the radioactive contamination that is embedded into the gunite walls. The MLDUA is also used to support waste sampling and wall core-sampling operations. Other tools that have been developed for use by the MLDUA include a pipe-plugging end effecter, pipe-cutting end effecter, and pipe-cleaning end effecter. Washington University developed advance robotics path control algorithms for use in the tanks. The MLDUA was first deployed in June 1997 and has operated continuously since then. Operational experience in the first four tanks remediated is presented in this paper

The Tri-Party Agreement was initiated in 1989 to provide a thirty-year clean-up plan for the United States Department of Energy's (DOE) Hanford Site. This plan addresses the remediation of hazardous chemical and radioactive wastes with a major emphasis on the characterization of Hanford's underground waste storage tanks. To assist in this task the DOE is funding the development of a light duty robotic arm capable of deploying various tools which can inspect and characterize the interior of DOE waste tanks. Current development includes two new technologies -- stereoscopic telepresence, which will allow three-dimensional viewing of the waste tank interior; and open-quotes virtual environmentsclose quotes (or open-quotes virtual realityclose quotes), which will provide computer-simulated world wherein operators can practice inspections and other activities prior to performing actual operations in real waste tanks

Safety equipment list for the light duty utility arm system

International Nuclear Information System (INIS)

Barnes, G.A.

1998-01-01

The initial issue (Revision 0) of this Safety Equipment List (SEL) for the Light Duty Utility Arm (LDUA) requires an explanation for both its existence and its being what it is. All LDUA documentation leading up to creation of this SEL, and the SEL itself, is predicated on the LDUA only being approved for use in waste tanks designated as Facility Group 3, i.e., it is not approved for use in Facility Group 1 or 2 waste tanks. Facility Group 3 tanks are those in which a spontaneous or induced hydrogen gas release would be small, localized, and would not exceed 25% of the LFL when mixed with the remaining air volume in the dome space; exceeding these parameters is considered unlikely. Thus, from a NFPA flammable gas environment perspective the waste tank interior is not classified as a hazardous location. Furthermore, a hazards identification and evaluation (HNF-SD-WM-HIE-010, REV 0) performed for the LDUA system concluded that the consequences of actual LDUA system postulated accidents in Flammable Gas Facility Group 3 waste tanks would have either NO IMPACT or LOW IMPACT on the offsite public and onsite worker. Therefore, from a flammable gas perspective, there is not a rationale for classifying any of SSCs associated with the LDUA as either Safety Class (SC) or Safety Significant (SS) SSCs, which, by default, categorizes them as General Service (GS) SSCs. It follows then, based on current PHMC procedures (HNF-PRO-704 and HNF-IP-0842, Vol IV, Section 5.2) for SEL creation and content, and from a flammable gas perspective, that an SEL is NOT REQ at sign D HOWEVER exclamation point exclamation point exclamation point There is both a precedent and a prudency to capture all SSCS, which although GS, contribute to a Defense-In-Depth (DID) approach to the design and use of equipment in potentially flammable gas environments. This Revision 0 of the LDUA SEL has been created to capture these SSCs and they are designated as GS-DID in this document. The specific reasons for

With the implementation of strict 80-hour work week in general surgery training, serious questions have been raised concerning the quality of surgical education and the ability of newly trained general surgeons to independently operate. Programs that were randomized to the interventional arm of the Flexibility In duty-hour Requirements for Surgical Trainees (FIRST) Trial were able to decrease transitions and allow for better continuity by virtue of less constraints on duty-hour rules. Using National Surgical Quality Improvement Program Quality In-Training Initiative data along with duty-hour violations compared with old rules, it was hypothesized that quality of care would be improved and outcomes would be equivalent or better than the traditional duty-hour rules. It was also hypothesized that resident perception of compliance with duty hour would not change with implementation of new regulations based on FIRST trial. Flexible work hours were implemented on July 1, 2014. National Surgical Quality Improvement Program Quality In-Training Initiative information was reviewed from July 2014 to January 2015. Patient risk factors and outcomes were compared between institutional resident cases and the national cohort for comparison. Residents' duty-hour logs and violations during this period were compared to the 6-month period before the implementation of the FIRST trial. The annual Accreditation Council for Graduate Medical Education resident survey was used to assess the residents' perception of compliance with duty hours. With respect to the postoperative complications, the only statistically significant measures were higher prevalence of pneumonia (3.4% vs. 1.5%, p flexible duty hours. All other measures of postoperative surgical complications showed no difference. The total number of duty-hour violations decreased from 54 to 16. Had the institution not been part of the interventional arm of the FIRST trial, this number would have increased to 238. The residents

DePasquale, Nicole; Bangerter, Lauren R; Williams, Jessica; Almeida, David M

2016-12-01

This study examines how certified nursing assistants (CNAs) balancing family caregiving roles-child care (double-duty child caregivers), elder care (double-duty elder caregivers), and both child and elder care (triple-duty caregivers)-utilize health care services relative to nonfamily caregiving counterparts (formal-only caregivers). A sample of 884 CNAs from the Work, Family and Health Study was drawn on to assess the number of acute care (i.e., emergency room or urgent care facility) and other health care (i.e., outpatient treatment or counseling) visits made during the past 6 months. Double-duty elder and triple-duty caregivers had higher acute care utilization rates than formal-only caregivers. CNAs with and without family caregiving roles had similar rates of other health care visits. CNAs providing informal care for older adults have higher acute care visit rates. Given the increasing need for family caregivers and the vital importance of the health of the nursing workforce for the health of others, future research on how double- and triple-duty caregivers maintain their health amidst constant caregiving should be a priority. © The Author 2015.

The Flexibility in Duty Hour Requirements for Surgical Trainees (FIRST) Trial randomly assigned surgical residency programs to either standard duty hour policies or flexible policies that eliminated caps on shift lengths and time off between shifts. Our objectives were to assess adherence to duty hour requirements in the Standard Policy arm and examine how often and why duty hour flexibility was used in the Flexible Policy arm. A total of 3,795 residents in the FIRST trial completed a survey in January 2016 (response rate >95%) that asked how often and why they exceeded current standard duty hour limits in both study arms. Flexible Policy interns worked more than 16 hours continuously at least once in a month more frequently than Standard Policy residents (86% vs 37.8%). Flexible Policy residents worked more than 28 hours once in a month more frequently than Standard Policy residents (PGY1: 64% vs 2.9%; PGY2 to 3: 62.4% vs 41.9%; PGY4 to 5: 52.2% vs 36.6%), but this occurred most frequently only 1 to 2 times per month. Although residents reported working more than 80 hours in a week 3 or more times in the most recent month more frequently under Flexible Policy vs Standard Policy (19.9% vs 16.2%), the difference was driven by interns (30.9% vs 19.6%), and there were no significant differences in exceeding 80 hours among PGY2 to 5 residents. The most common reasons reported for extending duty hours were facilitating care transitions (76.6%), stabilizing critically ill patients (70.7%), performing routine responsibilities (67.9%), and operating on patients known to the trainee (62.0%). There were differences in duty hours worked by residents in the Flexible vs Standard Policy arms of the FIRST trial, but it appeared that residents generally used the flexibility for patient care and educational opportunities selectively.

Finally, the influence and capacity of low-intensity training to influence metabolic fitness in the face of a limited effect on aerobic fitness will be challenged....... partitioning between endogenous and exogenous substrate during arm and leg exercise will be debated. Moreover the review will probe if differences between arm and leg muscle are merely a result of different training status rather than a qualitative difference in limb substrate regulation. Along this line...... the review will address the available studies on low-intensity training performed separately with arm or legs or as whole-body training to evaluate if this leads to different adaptations in arm and leg muscle resulting in different substrate utilization patterns during separate arm or leg exercise...

Utility of intraoperative diagnostic C-arm angiography for management of high grade subarachnoid hemorrhage

Directory of Open Access Journals (Sweden)

Zhikui Wei

2015-06-01

Full Text Available The accurate and efficient localization of underlying vascular lesions is crucial for prompt and definitive treatment of subarachnoid hemorrhage (SAH. To demonstrate the utility and feasibility of intraoperative C-arm angiography in cerebrovascular emergencies, we report five cases of high grade SAH and/or intracerebral hemorrhage (ICH where intraoperative diagnostic C-arm angiography was safely and effectively utilized. Initial evaluations of all patients included a non-contrast head CT scan, which was followed by urgent decompressive hemicraniectomy as a life-saving measure in the presence of markedly elevated intracranial pressure. Further diagnostic evaluations were performed intraoperatively using a multi-purpose C-arm angiography system. The C-arm angiography findings greatly aided the intraoperative planning and led to definitive treatments in four cases of SAH by elucidating the underlying neurovascular lesions. With this treatment strategy, two of the patients made moderately good recoveries from their SAH and/or ICH with a Glasgow outcome score (GOS of 4. Three of the patients expired despite maximal therapy mostly due to unfavorable presenting grade. These results suggest that C-arm angiography is a reasonable diagnostic and surgical planning tool for selected patients with high grade diffuse SAH who require immediate decompression.

Currently, Web-GIS technologies are widely used to generate a reliable and intuitive web-based interface to monitor the current radiation situation in various regions of the Russian Federation. The developed 'Server Web-Monitoring' web-application is intended for duty personnel and can operate not only on desktop computers but also on mobile devices. The subsystem of duty personnel notification about any Off-Normal Situation (ONS) (such as: critical threshold exceedances or failures in operation of monitoring systems) is also considered in the paper. Three types of Automated Radiation Monitoring Systems (ARMS) are available for monitoring: - regional ARMS; - facility-level ARMS; - ARMS of nuclear power plant surveillance areas. Google Maps and Google Maps API toolbox are used as the cartographic basis. In the general-monitoring window only general information on each of the local systems is available. Next, the operator can move to monitoring of local ARMS he is interested in. The operator can either view a list of Radiation Situation Monitoring Posts (RSMP) showing the current data in the right frame or hide it and use the map only. Viewing the log of critical threshold exceedances for 24 hours and a report on all RSMPs of a given system over the last 7 days is also possible. The report contains maximum values of measurements for every day and for each RSMP. The developed web-application includes: - monitoring of the radiation situation and its changes on the general map of the Russian Federation and on maps of local ARMS; - displaying 7-day reports for all RSMPs of the selected ARMS; - displaying the log of critical threshold exceedances recorded over the past day. The notification subsystem informs duty personnel on all ONS, namely, on critical threshold exceedances in the incoming data and failures in operation of monitoring systems. The key features of the notification subsystem are: - round-the-clock functioning; - automatic notification in case of

The Flexibility in Duty Hour Requirements for Surgical Trainees (FIRST) trial was a national, cluster-randomized, pragmatic, noninferiority trial of 117 general surgery programs, comparing standard ACGME resident duty hour requirements ("Standard Policy") to flexible, less-restrictive policies ("Flexible Policy"). Participating program directors (PDs) were surveyed to assess their perceptions of patient care, resident education, and resident well-being during the study period. A survey was sent to all PDs of the general surgery residency programs participating in the FIRST trial (N = 117 [100% response rate]) in June and July 2015. The survey compared PDs' perceptions of the duty hour requirements in their arm of the FIRST trial during the study period from July 1, 2014 to June 30, 2015. One hundred percent of PDs in the Flexible Policy arm indicated that residents used their additional flexibility in duty hours to complete operations they started or to stabilize a critically ill patient. Compared with the Standard Policy arm, PDs in the Flexible Policy arm perceived a more positive effect of duty hours on the safety of patient care (68.9% vs 0%; p care (98.3% vs 0%; p care (71.8%), continuity of care (94.0%), quality of resident education (83.8%), and resident well-being (55.6%) would be improved with a hypothetical permanent adoption of more flexible duty hours. Program directors involved in the FIRST trial perceived improvements in patient safety, continuity of care, and multiple aspects of resident education and well-being with flexible duty hours.

2017-10-03

Maternal mortality rates can be adversely affected by armed conflict, implying a greater level of vulnerability among women, and is often linked to the lack of or limited access to maternal healthcare during conflict. Previous research in Uganda has shown that armed conflict negatively impacts women's utilization of maternal healthcare services for a multitude of reasons at the individual, health-system and political levels. This study compared aggregated Demographic and Health Surveys data from 13 districts in Northern Uganda, a conflict-affected region, with data from the rest of the country, for the use of maternal healthcare services for the years 1988, 1995, 2000, 2006 and 2011, using statistical analyses and logistic regression. Specific indicators for maternal healthcare utilization included contraceptive use, antenatal care, skilled assistance at birth and institutional delivery. Use of contraception and institutional deliveries among women in Northern Uganda was significantly lower compared to the rest of the country. However, skilled assistance at birth among women in Northern Uganda was significantly higher. The findings in this study show that armed conflict can have a negative impact on aspects of maternal healthcare such as contraceptive use and institutional deliveries; however, other indicators such as skilled assistance at birth were seen to be better among conflict-affected populations. This reiterates the complex nature of armed conflict and the interplay of different factors such as conflict intensity, existing health systems and services, and humanitarian interventions that could influence maternal healthcare utilization.

Transarterial chemoembolization (TACE) is the well-known treatment for hepatocellular carcinoma. Multiple digital subtraction angiography (DSA) acquisitions in different projections are required to identify difficult arterial feeders. Moreover, the tell-tale tumor blush can be obscured by proximity to lung base, small size of lesion, and breathing artifacts. C-arm CT is a revolutionary advancement in the intervention radiology suite that allows acquisition of data which can be reformatted in multiple planes and volume rendered incorporating both soft tissue and vascular information like multidetector computed tomography (MDCT). These images acquired during the TACE procedure can provide critical inputs for achieving a safe and effective therapy. This case series aims to illustrate the utility of C-arm CT in solving specific problems encountered while performing TACE

Fitness for duty - a regulator's view

International Nuclear Information System (INIS)

Johnson, E.H.; Hall, R.E.

1987-01-01

Fitness for duty is a legal, moral, emotional, and political issue. It is therefore that type of issue that one would expect industry to run from, opting instead for government intervention and prescriptive regulations. This would allow the industry to hide behind the shield of doing what is necessary to comply. But fitness for duty is also a rational business issue. It involves getting a reasonable return on the investment in the people who are necessary to run the nuclear industry. It is within this context that the US Nuclear Regulatory Commission (NRC) has exercised its discretion to not undertake new rule making, instead giving the industry the mandate of pursuing this issue. The NRC has deferred rule making as long as the industry programs are effective in producing the desired results. The NRC has also retained the right to follow up on operational events and to evaluate the effectiveness of the programs in place. The industry, under the leadership of NUMARC, has risen to this challenge and has adopted the August 1985 Edison Electric Institute (EEI) fitness-for-duty program guidelines for implementation by all utilities. In evaluating the effectiveness of programs, the NRC is conducting inspections at some utilities. These inspections have confirmed that the EEI guidelines are being used as the basis for fitness-for-duty programs. Even though the nuclear industry has taken a generally strong stand on fitness for duty and has adopted reasonable guidelines for its assurance, there still remain several challenges

Strategies for redundancy resolution of dual-arm systems with passive elements for tank waste removal

International Nuclear Information System (INIS)

Dubey, R.

1997-01-01

The work described in this paper focuses on the coordination and control of two manipulators coupled by passive elements operating in a confined space. An example of one such system is the hardware used for the environmental response treatability study funded by the Department of Energy at Oak Ridge National Laboratory (ORNL). The motivation for this project is to establish the methodology necessary to extract large volumes of hazardous waste from underground storage facilities. The hardware used at ORNL consists of two long-reach manipulators. The first robot, the Modified Light Duty Utility Arm (MLDUA), is an 8-degree-of-freedom long-reach manipulator. The second arm, the Hose Management Arm (HMA), has two active degrees-of-freedom and provides hardware to break up and extract materials from the tank. Current strategies call for the MLDUA to grasp a combined sluicing end-effector attached, by a long flexible hose, to the HMA. The MLDUA will then move the combined system through the waste, extracting material. This paper describes many of the issues related to redundancy resolution and the coordinated control of these two robots. First, the authors provide a brief outline of the project and the existing hardware. This is followed by a description of existing redundancy resolution techniques and the impact redundancy has on the success of the project. Finally, preliminary simulation results show the effect cooperative control has on the level of forces generated between the dual-arm systems when coupled by an elastic exhaust hose. These results show a significant reduction in forces when both arms are active and have a combined manipulation strategy

About 45% of civilians who died by suicide had contact with a doctor within 1 month of death. Thus, educating primary care physicians (PCP) to detect and mitigate depression is an important suicide-prevention strategy. However, the PCP consulting rate before suicide has not been examined in a military population. We investigated the utilization of primary health care and mental health services by active-duty military personnel suicide cases prior to death in comparison to matched military controls. All suicides (N = 170) were extracted from a cohort of all active-duty Israeli military male personnel between 2002 and 2012. Applying a retrospective, nested case-control design, we compared primary care services utilization by suicide cases with demographic and occupationally matched military controls (N = 500). Whereas 38.3% of suicide cases contacted a PCP within the last month before death, only 27.6% of suicide cases contacted a mental health specialist during their entire service time. The PCP contact rate within 1 month before death or index day did not differ between suicide cases and military controls (38.3% vs. 33.8%, χ²₁ = 1.05, P = .3). More suicide cases contacted a mental health specialist within service time than did military controls (27.6% vs. 13.6%, χ²₁ = 10.85, P = .001). Even though PCP contact rate by military personnel who died by suicide is slightly lower than that reported for civilians who died by suicide prior to their death, it is higher than mental health specialist contact rate and higher than that by age-matched civilians who died by suicide. These results imply that PCPs education is a viable approach to suicide prevention in a military setting. © Copyright 2014 Physicians Postgraduate Press, Inc.

Biomedical Enhancement of Warfighters and the Legal Protection of Military Medical Personnel in Armed Conflict.

Science.gov (United States)

Liivoja, Rain

2017-10-24

Under international law, military medical personnel and facilities must be respected and protected in the event of an armed conflict. This special status only applies to personnel and facilities exclusively engaged in certain enumerated medical duties, especially the treatment of the wounded and sick, and the prevention of disease. Military medical personnel have, however, been called upon to engage in the biomedical enhancement of warfighters, as exemplified by the supply of central nervous system stimulants as a fatigue countermeasure. This article argues that international law of armed conflict does not recognise human enhancement as a medical duty, and that engaging in enhancement that is harmful to the enemy results in the loss of special protection normally enjoyed by military medical personnel and units. © The Author 2017.

For the inspection and light-duty maintenance of the vacuum vessel in the EAST tokamak, a serial robot arm, called EAST articulated maintenance arm, is developed. Due to the 9-m-long cantilever arm, the large flexibility of the EAMA robot introduces a problem in the accurate positioning. This article presents an autonomous robot control to cope with the robot positioning problem, which is a visual servo approach in context of tile grasping for the EAMA robot. In the experiments, the proposed method was implemented in a simulation environment to position and track a target graphite tile with the EAMA robot. As a result, the proposed visual control scheme can successfully drive the EAMA robot to approach and track the target tile until the robot reaches the desired position. Furthermore, the functionality of the simulation software presented in this paper is proved to be suitable for the development of the robotic and computer vision application.

Low back pain is a primary health care utilization driver in the US population. Health care evaluation visits for low back pain are as common as medical evaluation for the common cold. Low back pain is the most common reason for reductions in activities of daily living and work activity in the general population. Although these statistics are compelling, in the military population, there is arguably a significantly greater economic impact on the military population, as the cost to train, retain, and deploy a service member is a tremendous cost. The current study retrospectively examines surgical outcomes, return to duty, and patient-centric outcomes among 82 active duty or reserve military patients who underwent an outpatient minimally invasive spine surgery Laminotomy Foraminotomy Decompression for the treatment of lumbar spinal stenosis in an ambulatory surgery center. Overall, our results indicate that within the 82 active duty military service members, 100% of the service members return to duty within 3 mo. Additionally, there was a significant reduction in self-reported pain and disability 12 mo postoperative, whereas the average length of surgery was 62 min with an average estimated blood loss of 30.64 mL. The current study indicates that minimally invasive procedures for the treatment of lumbar spinal stenosis in an ambulatory surgery center setting are an effective option for active duty servicemen to reduce return-to-duty rates and symptomatic back-related pain and disability.

The Robotics Development Groups at the Savannah River Site (SRS) and at the Hanford site have developed remote video and photography systems for deployment in underground radioactive-waste storage tanks at the Department of Energy (DOE) sites as a part of the Office of Science and Technology (OST) program within DOE. Viewing and documenting the tank interiors and their associated annular spaces is an extremely valuable tool in characterizing their condition and contents and in controlling their remediation. Several specialized video/photography systems and robotic End Effectors have been fabricated that provide remote viewing and lighting. All are remotely deployable into and out of the tank, with all viewing functions remotely operated. Positioning all control components away from the facility prevents the potential for personnel exposure to radiation and contamination. Only the remote video systems are discussed in this paper

Zimmermann, Peter; Ströhle, Andreas; Langner, Franziska; Lanczik, Mario

2010-07-01

In 2001, women were admitted to all military careers in the German Armed Forces. This study examines whether the utilization of psychiatric services of female military personnel has changed since then. The central medical database of German military personnel for the years 2000 and 2006 was analyzed. Between 2000 and 2006, the percentage (based on the average totals of male and female military personnel) of consultations of primary care unit surgeons for psychiatric problems increased significantly for both male and female military personnel, this increase being more apparent for women than for men. Stress-related disorders showed the greatest rise. In 2006, as opposed to 2000, the total proportion of both outpatient and inpatient mental health treatment provided to female military personnel was significantly higher than for males, particularly regarding stress-related, affective and personality disorders. Gender-specific aspects should be considered more intensely in preventive and therapeutic psychiatric supply in the German Armed Forces.

This study examined rates of utilization of mental health care among active duty and National Guard soldiers with mental health problems three and 12 months after they returned from combat in Iraq. Stigma and barriers to care were also reported for each component (active duty and National Guard). Cross-sectional, anonymous surveys were administered to 10,386 soldiers across both time points and components. Mean scores from 11 items measuring stigma and barriers to care were computed. Service utilization was assessed by asking soldiers whether they had received services for a mental health problem from a mental health professional, a medical doctor, or the Department of Veterans Affairs in the past month. Risk of mental problems was measured using the Patient Health Questionnaire, the PTSD Checklist, and items asking about aggressive behaviors and "stress, emotional, alcohol, or family" problems within the past month. A higher proportion of active duty soldiers than National Guard soldiers reported at least one type of mental health problem at both three months (45% versus 33%) and 12 months (44% versus 35%) postdeployment. Among soldiers with mental health problems, National Guard soldiers reported significantly higher rates of mental health care utilization 12 months after deployment, compared with active duty soldiers (27% versus 13%). Mean stigma scores were higher among active duty soldiers than among National Guard soldiers. Active duty soldiers with a mental health problem had significantly lower rates of service utilization than National Guard soldiers and significantly higher endorsements of stigma. Current and future efforts to improve care for veterans should work toward reducing the stigma of receiving mental health care.

Full Text Available Norovirus is a leading cause of gastroenteritis episodes and outbreaks in US military deployments, but estimates of endemic disease burden among military personnel in garrison are lacking.Diagnostic codes from gastroenteritis-associated medical encounters of active duty military personnel and their beneficiaries from July 1998-June 2011 were obtained from the Armed Forces Health Surveillance Center. Using time-series regression models, cause-unspecified encounters were modeled as a function of encounters for specific enteropathogens. Model residuals (representing unexplained encounters were used to estimate norovirus-attributable medical encounters. Incidence rates were calculated using population data for both active duty and beneficiary populations.The estimated annual mean rate of norovirus-associated medically-attended visits among active duty personnel and their beneficiaries was 292 (95% CI: 258 to 326 and 93 (95% CI: 80 to 105 encounters per 10,000 persons, respectively. Rates were highest among beneficiaries <5 years of age with a median annual rate of 435 (range: 318 to 646 encounters per 10,000 children. Norovirus was estimated to cause 31% and 27% of all-cause gastroenteritis encounters in the active duty and beneficiary populations, respectively, with over 60% occurring between November and April. There was no evidence of any lag effect where norovirus disease occurred in one population before the other, or in one beneficiary age group before the others.Norovirus is a major cause of medically-attended gastroenteritis among non-deployed US military active duty members as well as in their beneficiaries.

Overview of psychiatric ethics V: utilitarianism and the ethics of duty.

Science.gov (United States)

Robertson, Michael; Morris, Kirsty; Walter, Garry

2007-10-01

The aim of this paper is to describe the ethical theories of utilitarianism and the ethics of duty (Kant's ethics) and to evaluate their value as theoretical bases of psychiatric ethics. Utilitarianism is a well-established moral philosophy and has significant instrumental value in dealing with common ethical problems faced by psychiatrists. Despite its capacity to generate solutions to ethical problems, utilitarianism requires a process of what Rawls described as 'reflective equilibrium' to avoid morally repugnant choices, based on utility. The criticisms of utilitarianism, such as the problems of quantifying utility and the responsibility for consequences, are very relevant for psychiatry. Singer's model of utilitarian thinking is particularly problematic for our profession. Kant's ethics provides the pretext for duty bound codes of ethics for psychiatrists, but suffers from problems of flawed claims to the universalizability prescribed by Kant's 'categorical imperative'. Kant's valorization of reason as the core of the autonomy of persons is a valuable insight in understanding psychiatrists' ethical obligations to their patients.

Liu, Tung-Kuan; Chen, Chiu-Hung; Tsai, Shang-En

2007-12-01

In this study, an optimization problem on the robot arm machining is formulated and solved by using genetic algorithms (GAs). The proposed approach adopts direct kinematics model and utilizes GA's global search ability to find the optimum solution. The direct kinematics equations of the robot arm are formulated and can be used to compute the end-effector coordinates. Based on these, the objective of optimum machining along a set of points can be evolutionarily evaluated with the distance between machining points and end-effector positions. Besides, a 3D CAD application, CATIA, is used to build up the 3D models of the robot arm, work-pieces and their components. A simulated experiment in CATIA is used to verify the computation results first and a practical control on the robot arm through the RS232 port is also performed. From the results, this approach is proved to be robust and can be suitable for most machining needs when robot arms are adopted as the machining tools.

A Fitness For Duty training program was developed to satisfy the requirements of the NRC, 10 CFR 26, 10 CFR 707 and to meet requirements at the Westinghouse Savannah River Company. Interactive videodisc technology was selected as the training medium using the TenCore authoring language. Computer-based training was chosen because of the large number of trainees, the advantages of the reduced overall cost, and the increased trainee retention of course material compared to traditional instruction. The resulting training program utilizes extensive role playing exercises in which employees and supervisors are exposed to real life situations. Extensive interactions by the trainees are required in that they must answer questions concerning the behav ior of individuals, random and for-cause drug testing, and the employee assistance program. Feedback is given in each case. Emphasis is placed on recognition of deteriorating job performance

Military duty: risk factor for preterm labor? A review.

Science.gov (United States)

McNeary, A M; Lomenick, T S

2000-08-01

The female military population represents a high-risk group for preterm labor and other adverse pregnancy outcomes. As the number of women entering the armed forces continues to increase, concerns regarding the effects of military service on pregnancy must persist. Although active duty females have access to prenatal care and maintain consistent follow-up, previous research has noted a 5-fold increase in preterm labor compared with civilian working women. Hospitalization and loss of work attributable to pregnancy complications directly affect productivity and mission accomplishment; therefore, it is crucial to identify those at risk to institute measures that will prevent such occurrences and decrease time away from work. This article provides a review of the existing literature concerning preterm labor in military women, comparisons with the civilian population, and recommendations for future research.

"A Kantian care ethics suicide duty".

Science.gov (United States)

Cooley, Dennis R

2013-01-01

Standard arguments for a duty to die or to commit suicide generally rely upon contractarian or other form of justice or the Principle of Beneficence. Even though some of these arguments might appear deontological, there is an explicit or implicit consequentialist common thread in all of them in which utility of some sort is maximized only through the taking of one's own life. Hence, most arguments for a suicide duty are consequentialist in nature. There are a number of relatively unexplored deontological arguments that make plausible cases for the mandatory taking of one's own life. For example, although Kant is widely thought to prohibit all suicides, a careful reading of his work can show a plausible case based on the Categorical Imperative. If it is necessary to preserve the individual's moral life, then everyone could will the generalized maxim governing the situation as a law of nature. Unfortunately, Kant's argument is weakened by his poor understanding of moral psychology. To strengthen Kant's case, care-relationship ethics can be combined with the argument to produce a plausible case that people are obligated to kill themselves if a number of criteria are satisfied.

Arm-in-Arm Response Regulator Dimers Promote Intermolecular Signal Transduction

Energy Technology Data Exchange (ETDEWEB)

Baker, Anna W.; Satyshur, Kenneth A.; Morales, Neydis Moreno; Forest, Katrina T. (UW)

2016-02-01

Bacteriophytochrome photoreceptors (BphPs) and their cognate response regulators make up two-component signal transduction systems which direct bacteria to mount phenotypic responses to changes in environmental light quality. Most of these systems utilize single-domain response regulators to transduce signals through unknown pathways and mechanisms. Here we describe the photocycle and autophosphorylation kinetics of RtBphP1, a red light-regulated histidine kinase from the desert bacteriumRamlibacter tataouinensis. RtBphP1 undergoes red to far-red photoconversion with rapid thermal reversion to the dark state. RtBphP1 is autophosphorylated in the dark; this activity is inhibited under red light. The RtBphP1 cognate response regulator, theR. tataouinensisbacteriophytochrome response regulator (RtBRR), and a homolog, AtBRR fromAgrobacterium tumefaciens, crystallize unexpectedly as arm-in-arm dimers, reliant on a conserved hydrophobic motif, hFWAhL (where h is a hydrophobic M, V, L, or I residue). RtBRR and AtBRR dimerize distinctly from four structurally characterized phytochrome response regulators found in photosynthetic organisms and from all other receiver domain homodimers in the Protein Data Bank. A unique cacodylate-zinc-histidine tag metal organic framework yielded single-wavelength anomalous diffraction phases and may be of general interest. Examination of the effect of the BRR stoichiometry on signal transduction showed that phosphorylated RtBRR is accumulated more efficiently than the engineered monomeric RtBRR (RtBRR_mon) in phosphotransfer reactions. Thus, we conclude that arm-in-arm dimers are a relevant signaling intermediate in this class of two-component regulatory systems.

BODY HEIGHT AND ITS ESTIMATION UTILIZING ARM SPAN MEASUREMENTS IN MALE ADOLESCENTS FROM CENTRAL REGION IN MONTENEGRO

2015-05-01

Full Text Available Anthropologists recognized the tallness of nations in the Dinaric Alps long time ago (Popovic et al, 2013. As the modern Montenegrins fall partly into the Dinaric racial classification (Bjelica et al., 2012, the purpose of this study was to examine the body height in Montenegrin male adolescents from central region as well as the relationship between arm span as an alternative to estimating the body height, which would vary from region to region in Montenegro. Method: Our investigation analyses 548 male adolescents from the central region in Montenegro. The anthropometric measurements were taken according to the protocol of the International Society for the Advancement of Kinanthropometry (ISAK. Means and standard deviations regarding the anthropometric measurements were obtained. A comparison of means of body heights and arm spans within this gender group were carried out using a t-test. The relationships between body height and arm span were determined using simple correlation coefficients and their 95% confidence interval. Then a linear regression analysis was performed to examine the extent to which the arm span can reliably predict body height. Results: The results displayed that male Central-Montenegrins are 183.66±6.93 cm tall and have an arm span of 184.99±8.30cm. Discussion: Compared to other studies, the results of this study have shown that this gender made Central-Macedonians the tall population, taller than general male population in Montenegro (Bjelica et al., 2012. On the other hand, expectably, the arm span reliably predicts body height in this gender. However, the estimation equations which have been obtained in Central-Montenegrins are, different alike in general population, since arm span was closer to body heights (1.33±1.37 centimetres, more than in general population (Bjelica et al., 2012. This confirms the necessity for developing separate height models for each region in Montenegro.

Natural Motives and the Motive of Duty: Hume and Kant on Our Duties to Others

OpenAIRE

Korsgaard, Christine M.

2009-01-01

Hume and Kant disagree about the motives involved in the performance of our duties to others. Hume thinks that natural virtues such as benevolence are best performed from “natural” motives, but that there are no natural motives for the performance of the “artificial” virtues, such as justice and fidelity to promises, which are performed from a sense of duty. Kant thinks all duties should be done from the motive of duty. In this paper, I examine the roots of the disagreement. If by a natural m...

A unique collaboration of female medical providers within the United States Armed Forces: rehabilitation of a marine with post-concussive vestibulopathy.

2005-01-01

Uncle Sam's loyal nieces have come a long way from the days of World War I. The development of occupational and physical therapy was heavily influenced by an early relationship with medical specialists during the First World War. This relationship can be considered largely responsible for the eventual acceptance (by the Armed Forces) of women working in this area. Over the past decade active duty women have seen many changes in opportunities to serve and are now stationed aboard aircraft carriers, performing roles previously considered for male personnel. We report a case study of the medical care provided by both military and civilian women working for the United States Armed Forces. Initial assessment was conducted in a battalion aid station of a United States Marine Corp base and the subject was then referred to a military medical center with highly technical vestibular assessment and rehabilitation services. The subject's case represents a unique collaboration of women therapists, enabling a Marines' access to timely and accurate assessment, treatment and ultimately, successful return to active duty. This case study is one of many examples of the acceptance and successful integration of women as providers of medical care within the Military's medical framework.

Full Text Available This study is based on measurements of Southern region Kosovan adolescents. The aim of this study was to examine the stature of adolescents from Southern region as well relationship between arm span and stature in both Kosovar genders. A total measured subject participated in this research was 225 out of which (105 girls and 120 boys, females average of age is 18.36±0.50 years old (range 18-20 years and for male 18.40±0.55 years old (range 18-20 years.The anthropometric measurements were done by trained people and were taken according to the ISAK manual. Relationship between stature and arm span has been analyzed by the simple correlation coeffi cient at a 95% confi dence interval. The linear regression analysis was carried out to examine extent to which arm span can reliably predict of stature. Statistical importance was placed at level p<0.05. As a result anthropometric measurements for both sexes showed that the average of stature for boys adolescents from Southern region are 178.60±5.73 centimeters and have the arm span average of 180.92±6.92 centimeters, while girls from Southern 165.33±4.45 centimeters tall, and have the arm span average of 165.60±6.03 centimeters. The results have shown that the arm span was estimated as a reliable indicator of stature assessment to the both genders adolescents from Southern region of Kosovo population. This study also confi rms the necessity for developing separate height models for each region in Kosovo.

Proprioceptive Interaction between the Two Arms in a Single-Arm Pointing Task.

Directory of Open Access Journals (Sweden)

Kazuyoshi Kigawa

Full Text Available Proprioceptive signals coming from both arms are used to determine the perceived position of one arm in a two-arm matching task. Here, we examined whether the perceived position of one arm is affected by proprioceptive signals from the other arm in a one-arm pointing task in which participants specified the perceived position of an unseen reference arm with an indicator paddle. Both arms were hidden from the participant's view throughout the study. In Experiment 1, with both arms placed in front of the body, the participants received 70-80 Hz vibration to the elbow flexors of the reference arm (= right arm to induce the illusion of elbow extension. This extension illusion was compared with that when the left arm elbow flexors were vibrated or not. The degree of the vibration-induced extension illusion of the right arm was reduced in the presence of left arm vibration. In Experiment 2, we found that this kinesthetic interaction between the two arms did not occur when the left arm was vibrated in an abducted position. In Experiment 3, the vibration-induced extension illusion of one arm was fully developed when this arm was placed at an abducted position, indicating that the brain receives increased proprioceptive input from a vibrated arm even if the arm was abducted. Our results suggest that proprioceptive interaction between the two arms occurs in a one-arm pointing task when the two arms are aligned with one another. The position sense of one arm measured using a pointer appears to include the influences of incoming information from the other arm when both arms were placed in front of the body and parallel to one another.

Duty Hour Reporting: Conflicting Values in Professionalism.

Science.gov (United States)

Byrne, John M; Loo, Lawrence K; Giang, Dan W

2015-09-01

Duty hour limits challenge professional values, sometimes forcing residents to choose between patient care and regulatory compliance. This may affect truthfulness in duty hour reporting. We assessed residents' reasons for falsifying duty hour reports. We surveyed residents in 1 sponsoring institution to explore the reasons for noncompliance, frequency of violations, falsification of reports, and the residents' awareness of the option to extend hours to care for a single patient. The analysis used descriptive statistics. Linear regression was used to explore falsification of duty hour reports by year of training. The response rate was 88% (572 of 650). Primary reasons for duty hour violations were number of patients (19%) and individual patient acuity/complexity (19%). Junior residents were significantly more likely to falsify duty hours (R = -0.966). Of 124 residents who acknowledged falsification, 51 (41%) identified the primary reason as concern that the program will be in jeopardy of violating the Accreditation Council for Graduate Medical Education (ACGME) duty hour limits followed by fear of punishment (34, 27%). This accounted for more than two-thirds of the primary reasons for falsification. Residents' falsification of duty hour data appears to be motivated by concerns about adverse actions from the ACGME, and fear they might be punished. To foster professionalism, we recommend that sponsoring institutions educate residents about professionalism in duty hour reporting. The ACGME should also convey the message that duty hour limits be applied in a no-blame systems-based approach, and allow junior residents to extend duty hours for the care of individual patients.

Summary Objectives Military organizations are keen to address barriers to mental health care yet stigma and barriers to care remain little understood, especially potential cultural differences between Armed Forces. The aim of this study was to compare data collected by the US, UK, Australian, New Zealand and Canadian militaries using Hoge et al.'s perceived stigma and barriers to care measure (Combat duty in Iraq and Afghanistan, mental health problems and barriers to care. New Engl J Med 2004;351:13–22). Design Each member country identified data sources that had enquired about Hoge et al.'s perceived stigma and perceived barriers to care items in the re-deployment or immediate post-deployment period. Five relevant statements were included in the study. Setting US, UK Australian, New Zealand and Canadian Armed Forces. Results Concerns about stigma and barriers to care tended to be more prominent among personnel who met criteria for a mental health problem. The pattern of reported stigma and barriers to care was similar across the Armed Forces of all five nations. Conclusions Barriers to care continue to be a major issue for service personnel within Western military forces. Although there are policy, procedural and cultural differences between Armed Forces, the nations studied appear to share some similarities in terms of perceived stigma and barriers to psychological care. Further research to understand patterns of reporting and subgroup differences is required. PMID:20382906

From the Sun's location in the Galactic disk, different arm tracers (CO, H I, hot dust, etc.) have been employed to locate a tangent to each spiral arm. Using all various and different observed spiral arm tracers (as published elsewhere), we embark on a new goal, namely the statistical analysis of these published data (data mining) to statistically compute the mean location of each spiral arm tracer. We show for a typical arm cross-cut, a separation of 400 pc between the mid-arm and the dust lane (at the inner edge of the arm, toward the Galactic center). Are some arms major and others minor? Separating arms into two sets, as suggested by some, we find the same arm widths between the two sets. Our interpretation is that we live in a multiple (four-arm) spiral (logarithmic) pattern (around a pitch angle of 12°) for the stars and gas in the Milky Way, with a sizable interarm separation (around 3 kpc) at the Sun's location and the same arm width for each arm (near 400 pc from mid-arm to dust lane).

Optimal arm posture control and tendon traction forces of a coupled tendon-driven manipulator

International Nuclear Information System (INIS)

Ma, Shugen

1997-01-01

In this study, the optimum arm posture of a coupled tendon-driven multijoint manipulator arm (or CT Arm) at maximum payload output was derived and the corresponding tendon traction forces were also analyzed, during management of a heavy payload by the manipulator in a gravity environment. The CT Arm is special tendon traction transmission mechanism in which a pair of tendons used to drive a joint is pulled from base actuators via pulleys mounted on the base-side joints. This mechanism enables optimal utilization of the coupled drive function of tendon traction forces and thus enables the lightweight manipulator to exhibit large payload capability. The properties of the CT Arm mechanism are elucidated by the proposed optimal posture control scheme. Computer simulation was also executed to verify the validity of the proposed control scheme.

Electrofishing power requirements in relation to duty cycle

Science.gov (United States)

Miranda, L.E.; Dolan, C.R.

2004-01-01

Under controlled laboratory conditions we measured the electrical peak power required to immobilize (i.e., narcotize or tetanize) fish of various species and sizes with duty cycles (i.e., percentage of time a field is energized) ranging from 1.5% to 100%. Electrofishing effectiveness was closely associated with duty cycle. Duty cycles of 10-50% required the least peak power to immobilize fish; peak power requirements increased gradually above 50% duty cycle and sharply below 10%. Small duty cycles can increase field strength by making possible higher instantaneous peak voltages that allow the threshold power needed to immobilize fish to radiate farther away from the electrodes. Therefore, operating within the 10-50% range of duty cycles would allow a larger radius of immobilization action than operating with higher duty cycles. This 10-50% range of duty cycles also coincided with some of the highest margins of difference between the electrical power required to narcotize and that required to tetanize fish. This observation is worthy of note because proper use of duty cycle could help reduce the mortality associated with tetany documented by some authors. Although electrofishing with intermediate duty cycles can potentially increase effectiveness of electrofishing, our results suggest that immobilization response is not fully accounted for by duty cycle because of a potential interaction between pulse frequency and duration that requires further investigation.

2017-06-01

Full Text Available This study is based on measurements of Central region Kosovar adolescents. The aim of this study was to examine the Body Height of adolescents from Central region as well relationship between arm span and Body Height in both Kosovar genders. A total measured subject participated in this research was 193 out of which (93 girls and 100 boys, females average of age is 18.15±0.35 years old (range 18-20 years and for male 18.26±0.44 years old (range 18-20 years. The anthropometric measurements were done by trained people and were taken according to the ISAK manual. Relationship between Body Height and arm span has been analyzed by the simple correlation coefficient at a 95% confidence interval. The linear regression analysis was carried out to examine extent to which arm span can reliably predict of Body Height. Statistical importance was placed at level p<0.05. As a result anthropometric measurements for both sexes showed that the average of Body Height for boys adolescents from Central region are 180.62±5.88 centimeters and have the arm span average of 181.36±7.08 centimeters, while girls from Central 166.77±4.71 centimeters tall, and have the arm span average of 167.08±5.03 centimeters. The results have shown that the arm span was estimated as a reliable indicator of Body Height assessment to the both genders adolescents from Central region of Kosovo population. This study also confirms the necessity for developing separate height models for each region in Kosovo.

Experiences and consequences for women with hand-arm vibration injuries.

Bylund, Sonya Hörnqwist; Ahlgren, Christina

2010-01-01

Vibrating machines are used in a variety of occupations. Exposure to hand-arm vibration can cause vascular, neurological, and muscular symptoms in the hands and arms. This qualitative study provides a deeper understanding of the consequences of vibration injuries in women. In depth interviews were conducted with eight women with vibration injuries. The women were metal and wood product assemblers and dental personnel. The transcribed interviews were analyzed in accordance with the grounded theory method. The core category in the findings was "another life". This was constructed by the categories "consequences for everyday activities", "work performance", "household duties", "leisure", and "self perception" and shows that the injury had affected most parts of the women's lives and decreased their quality of life. The importance of well-functioning hands in all activities was highlighted. Reduced hand function due to numbness, muscle weakness, and pain caused restricted abilities to perform activities at work, at home, and during leisure time. The women described impact on their self-perception, as the injury had affected them in their roles as a worker, mother, and woman. The findings indicate that a vibration injury is a multidimensional problem that can affect every aspect of an individual's life. Health care providers should be aware of these complex consequences.

In general, this disclosure is directed to a duty cycle correction (DCC) circuit that adjusts a falling edge of a clock signal to achieve a desired duty cycle. In some examples, the DCC circuit may generate a pulse in response to a falling edge of an input clock signal, delay the pulse based on a control voltage, adjust the falling edge of the input clock signal based on the delayed pulse to produce an output clock signal, and adjust the control voltage based on the difference between a duty cycle of the output clock signal and a desired duty cycle. Since the DCC circuit adjusts the falling edge of the clock cycle to achieve a desired duty cycle, the DCC may be incorporated into existing PLL control loops that adjust the rising edge of a clock signal without interfering with the operation of such PLL control loops.

For Industrial Wireless Sensor Networks (IWSNs), sending data with timely style to the stink (or control center, CC) that is monitored by sensor nodes is a challenging issue. However, in order to save energy, wireless sensor networks based on a duty cycle are widely used in the industrial field, which can bring great delay to data transmission. We observe that if the duty cycle of a small number of nodes in the network is set to 1, the sleep delay caused by the duty cycle can be effectively reduced. Thus, in this paper, a novel Portion of Nodes with Larger Duty Cycle (PNLDC) scheme is proposed to reduce delay and optimize energy efficiency for IWSNs. In the PNLDC scheme, a portion of nodes are selected to set their duty cycle to 1, and the proportion of nodes with the duty cycle of 1 is determined according to the energy abundance of the area in which the node is located. The more the residual energy in the region, the greater the proportion of the selected nodes. Because there are a certain proportion of nodes with the duty cycle of 1 in the network, the PNLDC scheme can effectively reduce delay in IWSNs. The performance analysis and experimental results show that the proposed scheme significantly reduces the delay for forwarding data by 8.9~26.4% and delay for detection by 2.1~24.6% without reducing the network lifetime when compared with the fixed duty cycle method. Meanwhile, compared with the dynamic duty cycle strategy, the proposed scheme has certain advantages in terms of energy utilization and delay reduction.

Post-traumatic stress and other problems often occur after combat, deployment, and other military operations. Because techniques such as mindfulness meditation show efficacy in improving mental health, our team developed a mobile application (app) for individuals in the armed forces with subclinical psychological problems as secondary prevention of more significant disease. Based on the Personal Health Intervention Toolkit (PHIT), a mobile app framework for personalized health intervention studies, PHIT for Duty integrates mindfulness-based relaxation, behavioral education in sleep quality and alcohol use, and psychometric and psychophysiological data capture. We evaluated PHIT for Duty in usability and health assessment studies to establish app quality for use in health research. Participants (N = 31) rated usability on a 1 (very hard) to 5 (very easy) scale and also completed the System Usability Scale (SUS) questionnaire (N = 9). Results were (mean ± SD) overall (4.5 ± 0.6), self-report instruments (4.5 ± 0.7), pulse sensor (3.7 ± 1.2), sleep monitor (4.4 ± 0.7), sleep monitor comfort (3.7 ± 1.1), and wrist actigraphy comfort (2.7 ± 0.9). The average SUS score was 85 ± 12, indicating a rank of 95%. A comparison of PHIT-based assessments to traditional paper forms demonstrated a high overall correlation (r = 0.87). These evaluations of usability, health assessment accuracy, physiological sensing, system acceptability, and overall functionality have shown positive results and affirmation for using the PHIT framework and PHIT for Duty application in mobile health research.

Evolution of robotic arms.

Moran, Michael E

The foundation of surgical robotics is in the development of the robotic arm. This is a thorough review of the literature on the nature and development of this device with emphasis on surgical applications. We have reviewed the published literature and classified robotic arms by their application: show, industrial application, medical application, etc. There is a definite trend in the manufacture of robotic arms toward more dextrous devices, more degrees-of-freedom, and capabilities beyond the human arm. da Vinci designed the first sophisticated robotic arm in 1495 with four degrees-of-freedom and an analog on-board controller supplying power and programmability. von Kemplen's chess-playing automaton left arm was quite sophisticated. Unimate introduced the first industrial robotic arm in 1961, it has subsequently evolved into the PUMA arm. In 1963 the Rancho arm was designed; Minsky's Tentacle arm appeared in 1968, Scheinman's Stanford arm in 1969, and MIT's Silver arm in 1974. Aird became the first cyborg human with a robotic arm in 1993. In 2000 Miguel Nicolalis redefined possible man-machine capacity in his work on cerebral implantation in owl-monkeys directly interfacing with robotic arms both locally and at a distance. The robotic arm is the end-effector of robotic systems and currently is the hallmark feature of the da Vinci Surgical System making its entrance into surgical application. But, despite the potential advantages of this computer-controlled master-slave system, robotic arms have definite limitations. Ongoing work in robotics has many potential solutions to the drawbacks of current robotic surgical systems.

Taking action on developmental toxicity: scientists' duties to protect children.

2012-09-10

Although adaptation and proper biological functioning require developmental programming, pollutant interference can cause developmental toxicity or DT. This commentary assesses whether it is ethical for citizens/physicians/scientists to allow avoidable DT. Using conceptual, economic, ethical, and logical analysis, the commentary assesses what major ethical theories and objectors would say regarding the defensibility of allowing avoidable DT. The commentary argues that (1) none of the four major ethical theories (based, respectively, on virtue, natural law, utility, or equity) can consistently defend avoidable DT because it unjustifiably harms, respectively, individual human flourishing, human life, the greatest good, and equality. (2) Justice also requires leaving "as much and as good" biological resources for all, including future generations possibly harmed if epigenetic change is heritable. (3) Scientists/physicians have greater justice-based duties, than ordinary/average citizens, to help stop DT because they help cause it and have greater professional abilities/opportunities to help stop it. (4) Scientists/physicians likewise have greater justice-based duties, than ordinary/average citizens, to help stop DT because they benefit more from it, given their relatively greater education/consumption/income. The paper shows that major objections to (3)-(4) fail on logical, ethical, or scientific grounds, then closes with practical suggestions for implementing its proposals. Because allowing avoidable DT is ethically indefensible, citizens---and especially physicians/scientists---have justice-based duties to help stop DT.

Visual Recognition and Its Application to Robot Arm Control

Full Text Available This paper presents an application of optical word recognition and fuzzy control to a smartphone automatic test system. The system consists of a robot arm and two webcams. After the words from the control panel that represent commands are recognized by the robot system, the robot arm performs the corresponding actions to test the smartphone. One of the webcams is utilized to capture commands on the screen of the control panel, the other to recognize the words on the screen of the tested smartphone. The method of image processing is based on the Red-Green-Blue (RGB and Hue-Saturation-Luminance (HSL color spaces to reduce the influence of light. Fuzzy theory is used in the robot arm’s position control. The Optical Character Recognition (OCR technique is applied to the word recognition, and the recognition results are then checked by a dictionary process to increase the recognition accuracy. The camera which is used to recognize the tested smartphone also provides object coordinates to the fuzzy controller, then the robot arm moves to the desired positions and presses the desired buttons. The proposed control scheme allows the robot arm to perform different assigned test functions successfully.

The use of robotics for benign etiology in gynecology has not proven to be more beneficial when compared to traditional laparoscopy. The major concern regarding robotic hysterectomy stems from its high cost. To evaluate the clinical utility and effectiveness of one-arm reduced robotic-assisted laparoscopic hysterectomy as a cost-effective surgical option for total robotic hysterectomy. A sample population of 54 women who underwent robotic-assisted laparoscopic surgery for benign gynecologic indications was evaluated, and two groups were identified: (1) the two-armed robotic-assisted laparoscopic surgery group (n = 38 patients), and (2) the three-armed robotic-assisted laparoscopic surgery group (n = 16 patients). An increased cost was observed when three-armed robotic surgery was employed for benign gynecologic surgery (p < 0.001). The cost reduction observed in the study group was primarily derived from one robotic arm reduction and vaginal closure of the cuff. This cost reduction was achieved without an increase in complication rates or undesirable postoperative outcomes. An estimated profit between $399.5 and $421.5 was made for each patient depending on the suture material chosen for cuff closure. Two-armed surgery resulted in an 18.6% reduction in procedure-specific costs for robotic hysterectomy. Two-armed robotic-assisted laparoscopic hysterectomy appears to be a cost-effective solution for robotic gynecologic surgery. This surgical solution can be performed as effectively as classical three-armed robotic hysterectomies for benign indications without the risk of increased surgical-related morbidities. This approach has the potential to be a widely preferred surgical approach in medical communities where cost reduction is one of the primary determinants of surgery type.

Quantification of the gravity-dependent change in the C-arm image center for image compensation in fluoroscopic spinal neuronavigation.

2001-01-01

In the quest to develop a viable, frameless spinal navigation system, many researchers are utilizing the C-arm fluoroscope. However, there is a significant problem with the C-arm that must be quantified: the gravity-dependent sag effect resulting from the geometry of the C-arm and aggravated by the inequity of weight at each end of the C-arm. This study quantified the C-arm sag effect, giving researchers the protocol and data needed to develop a program that accounts for this distortion. The development of spinal navigation algorithms that account for the C-arm sag effect should produce a more accurate spinal navigation system.

Kootenay Lake Fertilization Experiment, Year 15 (North Arm) and Year 3 (South Arm) (2006) Report

Energy Technology Data Exchange (ETDEWEB)

Schindler, E.U.; Sebastian, D.; Andrusak, G.F. [Fish and Wildlife Science and Allocation, Ministry of Environment, Province of British Columbia

2009-07-01

This report summarizes results from the fifteenth year (2006) of nutrient additions to the North Arm of Kootenay Lake and three years of nutrient additions to the South Arm. Experimental fertilization of the lake has been conducted using an adaptive management approach in an effort to restore lake productivity lost as a result of nutrient uptake in upstream reservoirs. The primary objective of the experiment is to restore kokanee (Oncorhynchus nerka) populations, which are the main food source for Gerrard rainbow trout (Oncorhynchus mykiss) and bull trout (Salvelinus confluentus). The quantity of agricultural grade liquid fertilizer (10-34-0, ammonium polyphosphate and 28-0-0, urea ammonium nitrate) added to the North Arm in 2006 was 44.7 tonnes of P and 248.4 tonnes of N. The total fertilizer load added to the South Arm was 257 tonnes of nitrogen; no P was added. Kootenay Lake has an area of 395 km{sup 2}, a maximum depth of 150 m, a mean depth of 94 m, and a water renewal time of approximately two years. Kootenay Lake is a monomictic lake, generally mixing from late fall to early spring and stratifying during the summer. Surface water temperatures generally exceed 20 C for only a few weeks in July. Results of oxygen profiles were similar to previous years with the lake being well oxygenated from the surface to the bottom depths at all stations. Similar to past years, Secchi disc measurements at all stations in 2006 indicate a typical seasonal pattern of decreasing depths associated with the spring phytoplankton bloom, followed by increasing depths as the bloom gradually decreases by the late summer and fall. Total phosphorus (TP) ranged from 2-7 {micro}g/L and tended to decrease as summer advanced. Over the sampling season dissolved inorganic nitrogen (DIN) concentrations decreased, with the decline corresponding to nitrate (the dominant component of DIN) being utilized by phytoplankton during summer stratification. Owing to the importance of epilimnetic nitrate

1995-10-01

Whole body cooling impairs manual arm performance. The independent contributions of local (peripheral) and/or whole body (central) cooling are not known. Therefore, a protocol was developed in which the arm and the rest of the body could be independently cooled. Biceps temperature (Tmus), at a depth of 20 mm, and esophageal temperature (Tes) were measured. Six subjects were immersed to the clavicles in a tank (body tank) of water under 3 conditions: 1) cold body-cold arm (CB-CA); 2) warm body-cold arm (WB-CA); and 3) cold body-warm arm (CB-WA). In the latter two conditions, subjects placed their dominant arm in a separate (arm) tank. Water temperature (Tw) in each tank was independently controlled. In conditions requiring cold body and/or cold arm, Tw in the appropriate tanks was 8 degrees C. In conditions requiring warm body and/or warm arm, Tw in the appropriate tanks was adjusted between 29 and 38 degrees C to maintain body/arm temperature at baseline values. A battery of 6 tests, requiring fine or gross motor movements, were performed immediately before immersion and after 15, 45, and 70 minutes of immersion. In CB-CA, Tes decreased from an average of 37.2 to 35.6 degrees C and Tmus decreased from 34.6 to 22.0 degrees C. In WB-CA, Tmus decreased to 18.1 degrees C (Tes = 37.1 degrees C), and in CB-WA, Tes decreased to 35.8 degrees C (Tmus = 34.5 degrees C). By the end of immersion, there were significant decrements (43-85%) in the performance of all tests in CB-CA and WB-CA (p body and/or the arm elicits large decrements in finger, hand and arm performance. The decrements are due almost entirely to the local effects of arm tissue cooling.

Due diligence duties for an environmental liability

International Nuclear Information System (INIS)

Huebsch, M.

2000-04-01

Jurisdiction turned out well to create a basic ruling for due diligence duties. These due diligence duties are high standards for the law of torts (outside of contracts) within the Austrian civil law and represent a liability-extension for the holder of the source of danger. They establish an action for injunction in particular for preventing (further) damages. Therewith due diligence duties get a general sense in the range of a civil law for environmental liability. The responsible holder of a danger zone will therefore influence his way of acting to protect potential victims and the environment. The burden of proof is on the plaintiff (victims) under the Civil Code. Victims have specific sources of danger including high endangering special facilities in their argumentation with the so-called prima-facie-proof or first-appearance-proof. A turning back of the presentation of evidence to the polluter is wrong. The polluter himself has a continuing liability for dangerous activities and his clerks in the case of an extremely high danger of damage. All due diligence duties can be arranged in three areas: in information-, danger-avoidance- and danger-prevention-duties. The determination of range and essence of the duties has to be adjusted to each individual case. The range of the specific danger area is the essential link. The intensity of due diligence duties is increasing with the size of danger in the way of a movable system depending on the protected interest. Due diligence duties have to be kept within reasonable limits with two criterions: necessarity and demand. Proportionality of actions is a third criterion to avoid exaggeration of due diligence duties to obtain an effective protection for victims including the environment. (author)

Student midwives' duty hours: risks, standards, and recommendations.

Lawrence, Rachel; Kantrowitz-Gordon, Ira; Landis, Andrea

2014-01-01

A growing body of literature has emerged describing the risks of extended-duty shifts and sleep deprivation. Worldwide, midwifery organizations have not adopted standards for practitioner or student duty shifts. This project reviews the literature related to extended-duty shifts in an effort to develop evidence-based recommendations for student nurse-midwives/student midwives (SNMs/SMs). A comprehensive literature search was conducted through electronic databases, major journals, and reference lists published in English since January 2001. Primary research studies evaluating sleep deprivation and shift duration were included. Studies that did not include the target population (shift workers) and those that formed conclusions related to extended-duty shifts greater than 30 hours were excluded. In addition, an extensive worldwide review of duty-hour recommendations from more than 300 health care organizations was conducted. A total of 40 studies met the inclusion criteria. Extended-duty shifts (those greater than 12 hours) increased the risk for cognitive and physical functional errors, safety concerns, and decreased quality of life from sleep deprivation. Cognitive function errors included attention lapses, visual tracking errors, decreased mentation and immediate recall, and decreased learning capacity. Physical errors included decreased motor skills and slowed reaction times in clinical simulations. These deficits led to an increased risk of motor vehicle accidents, needle sticks, and performance equivalent to unsafe blood alcohol concentrations. An overall decrease in quality of life and job satisfaction was linked to extended-duty shifts. Seven organizations for medical residents or advanced practice nurses have developed policy statements on duty shifts, with extended-duty shift limitations between 12 and 24 hours. The risks associated with extended-duty shifts may inhibit the development of SNMs/SMs into competent practitioners and place patients at risk. It

Mirror therapy has been performed as effective occupational therapy in a clinical setting for functional recovery of a hemiplegic arm after stroke. It is conducted by eliciting an illusion through use of a mirror as if the hemiplegic arm is moving in real-time while moving the healthy arm. It can facilitate brain neuroplasticity through activation of the sensorimotor cortex. However, conventional mirror therapy has a critical limitation in that the hemiplegic arm is not actually moving. Thus, we developed a real-time 2-axis mirror robot system as a simple add-on module for conventional mirror therapy using a closed feedback mechanism, which enables real-time movement of the hemiplegic arm. We used 3 Attitude and Heading Reference System sensors, 2 brushless DC motors for elbow and wrist joints, and exoskeletal frames. In a feasibility study on 6 healthy subjects, robotic mirror therapy was safe and feasible. We further selected tasks useful for activities of daily living training through feedback from rehabilitation doctors. A chronic stroke patient showed improvement in the Fugl-Meyer assessment scale and elbow flexor spasticity after a 2-week application of the mirror robot system. Robotic mirror therapy may enhance proprioceptive input to the sensory cortex, which is considered to be important in neuroplasticity and functional recovery of hemiplegic arms. The mirror robot system presented herein can be easily developed and utilized effectively to advance occupational therapy.

PURPOSE To analyze the relationship between ARMS2 and HTRA1 in the association with age-related macular degeneration (AMD) in an independent case-control dataset, and to investigate the subcellular localization of the ARMS2 protein in an in vitro system. METHOD Two SNPs in ARMS2 and HTRA1 were genotyped in 685 cases and 269 controls by Taqman Assay. Allelic association was tested by a χ2 test. A likelihood ratio test (LRT) of full vs. reduced models was utilized to analyze the interaction between ARMS2 and smoking and HTRA1 and smoking, after adjusting for CFH and age. Immunofluorescence and immunoblot were applied to localize ARMS2 in retinal epithelial ARPE-19 cells and COS7 cell transfected by ARMS2 constructs. RESULT Both significantly associated SNP rs10490924 and rs11200638 (P<0.0001) are in strong linkage disequilibrium (LD) (D′=0.97, r2=0.93) that generates virtually identical association test and odds ratios. In separate logistic regression models the interaction effect for both smoking with ARMS2 and with HTRA1 was not statistically significant. Immunofluorescence and immunoblot show that both endogenous and exogenous ARMS2 are mainly distributed in the cytosol, not the mitochondria. Comparing to wild type, ARMS2 A69S is more likely to be associated with cytoskeleton in COS7 cells. CONCLUSIONS The significant associations in ARMS2 and HTRA1 are with polymorphisms in strong LD that confer virtually identical risks, preventing differentiation at the statistical level. We found that ARMS2 was mainly distributed in the cytosol, not in mitochondrial outer membrane as previously reported, suggesting that ARMS2 may not confer risk to AMD through the mitochondrial pathway.

Operation of manipulator systems in poorly defined work environments often presents a significant hazard to both the robotic assembly and the environment. In applications relating to the Environmental Restoration and Waste Management (ER ampersand WM) Program, many of the environments are considered hazardous, both, in the structure and composition of the environment Use of a sensing system that provides information to the manipulator control unit regarding obstacles in close proximity will provide protection against collisions. In this paper, a hierarchical design and implementation of a whole-arm obstacle avoidance system is presented. The system is based on capacitive sensors configured as bracelets for proximity sensing. Each bracelet contains a number of sensor nodes and a processor for sensor node control and readout, and communications with a higher level host, common to all bracelets. The host controls the entire sensing network and communicates proximity information to the manipulator controller. The overall architecture of this system is discussed with detail on the individual system modules. Details of an application specific integrated circuit (ASIC) designed to implement the sensor node electronics are presented. Justifications for the general measurement methods and associated implementation are discussed. Additionally, the current state of development including measured dam is presented

Electromechanical and robot-assisted arm training devices are used in rehabilitation, and may help to improve arm function after stroke. To assess the effectiveness of electromechanical and robot-assisted arm training for improving activities of daily living, arm function, and arm muscle strength in people after stroke. We also assessed the acceptability and safety of the therapy. We searched the Cochrane Stroke Group's Trials Register (last searched February 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2015, Issue 3), MEDLINE (1950 to March 2015), EMBASE (1980 to March 2015), CINAHL (1982 to March 2015), AMED (1985 to March 2015), SPORTDiscus (1949 to March 2015), PEDro (searched April 2015), Compendex (1972 to March 2015), and Inspec (1969 to March 2015). We also handsearched relevant conference proceedings, searched trials and research registers, checked reference lists, and contacted trialists, experts, and researchers in our field, as well as manufacturers of commercial devices. Randomised controlled trials comparing electromechanical and robot-assisted arm training for recovery of arm function with other rehabilitation or placebo interventions, or no treatment, for people after stroke. Two review authors independently selected trials for inclusion, assessed trial quality and risk of bias, and extracted data. We contacted trialists for additional information. We analysed the results as standardised mean differences (SMDs) for continuous variables and risk differences (RDs) for dichotomous variables. We included 34 trials (involving 1160 participants) in this update of our review. Electromechanical and robot-assisted arm training improved activities of daily living scores (SMD 0.37, 95% confidence interval (CI) 0.11 to 0.64, P = 0.005, I² = 62%), arm function (SMD 0.35, 95% CI 0.18 to 0.51, P arm muscle strength (SMD 0.36, 95% CI 0.01 to 0.70, P = 0.04, I² = 72%), but the quality of the evidence was low to very low

Reduced-dose C-arm computed tomography (CT) uses flat-panel detectors to acquire real-time 3-D images in the interventional radiology suite to assist with anatomical localization and procedure planning. To describe dose-reduction techniques for C-arm CT at a pediatric institution and to provide guidance for implementation. We conducted a 5-year retrospective study on procedures using an institution-specific reduced-dose protocol: 5 or 8 s Dyna Rotation, 248/396 projection images/acquisition and 0.1-0.17 μGy/projection dose at the detector with 0.3/0.6/0.9-mm copper (Cu) filtration. We categorized cases by procedure type and average patient age and calculated C-arm CT and total dose area product (DAP). Two hundred twenty-two C-arm CT-guided procedures were performed with a dose-reduction protocol. The most common procedures were temporomandibular and sacroiliac joint injections (48.6%) and sclerotherapy (34.2%). C-arm CT was utilized in cases of difficult percutaneous access in less common applications such as cecostomy and gastrostomy placement, foreign body retrieval and thoracentesis. C-arm CT accounted for between 9.9% and 80.7% of the total procedural DAP. Dose-reducing techniques can preserve image quality for intervention while reducing radiation exposure to the child. This technology has multiple applications within pediatric interventional radiology and can be considered as an adjunctive imaging tool in a variety of procedures, particularly when percutaneous access is challenging despite routine fluoroscopic or ultrasound guidance.

Kinematics and duty cycles of the SM-229 force-reflecting servomanipulator

International Nuclear Information System (INIS)

Stoughton, R.S.

1986-02-01

This report describes the first known experimental study of servomanipulator duty cycles to appear in the literature. The servomanipulator used was TeleOperator Systems Model SM-229. The experimental approach used was to record the joint positions and motor currents of the right slave arm at a rate of 10 Hz over about 50 h of typical remote manipulation operations. The results are presented as position usage patterns in joint and real-world coordinates, time-use histograms of joint velocities and motor currents, and three-dimensional mechanical power histograms for each joint. All results are presented in dimensionless form, scaled to the design ranges of the manipulator and the total operation time recorded. Applications of this study include improvements in kinematic ranges, gear reductions, motor sizings, drive configurations, and stress relief. Included in appendices are an uncertainty analysis, calibration procedures, and analysis of the kinematics of the manipulator. 12 refs., 42 figs., 15 tabs

Many daily activities, from basic grooming to employment tasks, require adequate unsupported arm endurance (UAE). We developed an electromechanical device to measure UAE endurance. The purpose of this study was to standardize the instrument for two rates of arm motion, moderate and slow, in 18 normal adult subjects (FEVI = 3.7L +/- .78, FVC = 4.2L +/- .74, FEV1/FVC = 1.1 +/- .08). Exercise endurance limits, and the following metabolic, ventilatory, and sensation responses were determined at rest prior to exercise and at end-exercise limits for both rates of UAE:minute ventilation (Ve), tidal volume (VT), respiratory rate (RR), duty cycle (Ti/Ttot), oxygen uptake (VO2), carbon dioxide production (VCO2), inspiratory flow (VT/Ti), heart rate (HR), and visual analog scale measurements (VAS) of dyspnea (D), respiratory effort (RE), and arm fatigue (AF). Significance increases from baseline rest were shown at the endurance limits for both rates of UAE in: VO2, VCO2, Ve, VT, RR, VT/Ti, HR, VAS-D, VAS-RE, and VAS-AF. There were no changes in Ti/Ttot and SaO2 with UAE. Peak VO2, RR, Ve, VT/Ti, and VAS-D with moderate exercise were significantly greater than slow UAE; and there was a trend increase in peak HR for moderate as opposed to slow rate UAE. Despite these differences, the endurance time between the two rates of UAE were similar. These data provide standards against which UAE in COPD can be evaluated.

We study the mechanism of human arm-posture control by means of nonlinear dynamics and quantitative time series analysis methods. Utilizing linear and nonlinear measures in combination, we find that pathological tremors emerge in patient dynamics and serve as a main feature discriminating between normal and patient groups. The deterministic structure accompanied with loss of complexity inherent in the tremor dynamics is also revealed. To probe the underlying mechanism of the arm-posture dynamics, we further analyze the coupling patterns between joints and components, and discuss their roles in breaking of the organization structure. As a result, we elucidate the mechanisms in the arm-posture dynamics of normal subjects responding to the gravitational force and for the reduction of the dynamic degrees of freedom in the patient dynamics. This study provides an integrated framework for the origin of the loss of complexity in the dynamics of patients as well as the coupling structure in the arm-posture dynamics.

Full Text Available Tulsi Ram Bhandari, Prabhakaran Sankara Sarma, Vellappillil Raman Kutty Achutha Menon Centre for Health Science Studies, Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, Kerala, India Background: Despite a decade-long armed conflict in Nepal, the country made progress in reducing maternal mortality and is on its way to achieve the Millennium Development Goal Five. This study aimed to assess the degree of the utilization of maternal health care services during and after the armed conflict in Nepal.Methods: This study is based on Nepal Demographic and Health Survey data 2006 and 2011. The units of analysis were women who had given birth to at least one child in the past 5 years preceding the survey. First, we compared the utilization of maternal health care services of 2006 with that of 2011. Second, we merged the two data sets and applied logistic regression to distinguish whether the utilization of maternal health care services had improved after the peace process 2006 was underway.Results: In 2011, 85% of the women sought antenatal care at least once. Skilled health workers for delivery care assisted 36.1% of the women, and 46% of the women attended postnatal care visit at least once. These figures were 70%, 18.7%, and 16%, respectively, in 2006. Similarly, women were more likely to utilize antenatal care at least once (odds ratio [OR] =2.18, confidence interval [CI] =1.95–2.43, skilled care at birth (OR =2.58, CI =2.36–2.81, and postnatal care at least once (OR =4.13, CI =3.75–4.50 in 2011.Conclusion: The utilization of maternal health care services tended to increase continuously during both the armed conflict and the post-conflict period in Nepal. However, the increasing proportion of the utilization was higher after the Comprehensive Peace Process Agreement 2006.

We report on a 5-year multi-institution and multi-agency airborne study of atmospheric composition and carbon cycling at the Atmospheric Radiation Measurement (ARM) Climate Research Facility’s Southern Great Plains (SGP) site, with scientific objectives that are central to the carbon-cycle and radiative-forcing goals of the U.S. Global Change Research Program and the North American Carbon Program (NACP). The goal of these measurements is to improve understanding of 1) the carbon exchange of the Atmospheric Radiation Measurement (ARM) SGP region; 2) how CO₂ and associated water and energy fluxes influence radiative-forcing, convective processes, and CO₂ concentrations over the ARM SGP region, and 3) how greenhouse gases are transported on continental scales.

A call of duty in hard times: Duty to vote and the Spanish Economic Crisis

Directory of Open Access Journals (Sweden)

Carol Galais

2014-06-01

Full Text Available Although scarce, the literature addressing the effects of the economy on voter turnout and political attitudes has yielded mixed results. By using individual, longitudinal data from Spain—a country devastated by the Great Recession—our study illuminates how the latest economic crisis has impacted citizens’ perceptions of voting. We analyze how economic conditions and perceptions of the economy have transformed the belief that voting is a civic duty, which is one of the strongest attitudinal predictors of turnout. Our results suggest that hard times slightly weaken citizens’ sense of civic duty, particularly among the youngest. However, the adverse effects of the economic crisis are compensated by the positive effects of the electoral context, and as a consequence there is no aggregate decline in civic duty during the period examined (2010–2012.

State duties of protection and fundamental rights

C Starck

Full Text Available Duties of protection are duties of the state to protect certain legal interests of its citizens. They cover the interests of life, health, freedom and property and also protect some other interests and certain constitutionally recognised institutions. State duties of protection must be considered in connection with fundamental rights. The foundations of modern constitutionalism and attendant procedures are essential to develop guidelines for a constructive critique of the jurisprudence of the Constitutional Court. This is done with reference to the recent history of France, Germany and England. The historical excursus reveals that a single theory underlies the variety of constitutional states. The development of the constitutional state gave rise to the significance of the preservation of freedom through the maintenance of law and the separation of powers. This has given rise to various legal devices, based also in part on experience with moderate rule and earlier theories of the imperium limitatum.A textual analysis of the German Basic Law is undertaken to determine whether and how the duties of protection are expressly created. Furthermore, the duties that have been discovered in the Basic Law by the Federal Constitutional Court are considered. These duties include the protection of human life and health, personal freedom, the right to autonomous development of one's personality, freedom of science, research and teaching, marriage and the family, children, mothers, professional freedom, property and the protection of German nationals against foreign states. Finally the justification of such duties and the constitutional control of the manner of protection are considered.In a final section a critique of relevant constitutional jurisprudence is undertaken. It is argued that claims to protection cannot be directly binding law. They presuppose legislation. If statutory protection is connected with infringements of third-party fundamental rights

Nurses are expected to discharge their duty of care effectively and professionally to prevent medical negligence. Only three articles have previously focused on medical negligence. Duty of care and medical negligence in nursing are topics that have been neglected in Taiwan. (1) Classify the duty of care of professional nurses; (2) Investigate the facts and disputes in the current case; (3) Clarify the legal issues involved with regard to duty-of-care violations in the current case; (4) Explore the causal relationships in a legal context between nurses' duty-of-care violations and patient harm / injury. Literature analysis and a case study are used to analyze Supreme Court Verdict No.5550 (2010). Duty of care for nursing professionals may be classified into seven broad categories. Each category has its distinct correlatives. In nursing practice, every nursing behavior has a corresponding duty. In this case, the case study nurse did not discharge her obstetric professional duty and failed to inform the doctor in a timely manner. Negligence resulted in prenatal death and the case study nurse was found guilty. In order to prevent committing a crime, nurses should gain a better understanding of their duty of care and adequately discharge these duties in daily practice.

Towards a Duty of Care for Biodiversity

Science.gov (United States)

Earl, G.; Curtis, A.; Allan, C.

2010-04-01

The decline in biodiversity is a worldwide phenomenon, with current rates of species extinction more dramatic than any previously recorded. Habitat loss has been identified as the major cause of biodiversity decline. In this article we suggest that a statutory duty of care would complement the current mix of policy options for biodiversity conservation. Obstacles hindering the introduction of a statutory duty of care include linguistic ambiguity about the terms ‘duty of care’ and ‘stewardship’ and how they are applied in a natural resource management context, and the absence of a mechanism to guide its implementation. Drawing on international literature and key informant interviews we have articulated characteristics of duty of care to reduce linguistic ambiguity, and developed a framework for implementing a duty of care for biodiversity at the regional scale. The framework draws on key elements of the common law ‘duty of care’, the concepts of ‘taking reasonable care’ and ‘avoiding foreseeable harm’, in its logic. Core elements of the framework include desired outcomes for biodiversity, supported by current recommended practices. The focus on outcomes provides opportunities for the development of innovative management practices. The framework incorporates multiple pathways for the redress of non-compliance including tiered negative sanctions, and positive measures to encourage compliance. Importantly, the framework addresses the need for change and adaptation that is a necessary part of biodiversity management.

A remote operated control arm for powered manipulators is described. It includes an assembly allowing several movements with position sensors for each movement. The number of possible arm movements equals the number of possible manipulator movements. The control systems may be interrupted as required. One part of the arm is fitted with a system to lock it with respect to another part of the arm without affecting the other movements, so long as the positions of the manipulator and the arm have not been brought into complete coincidence. With this system the locking can be ended when complete concordance is achieved [fr

From October 1, 2015 through September 30, 2016, AAF deployed a Cessna 206 aircraft over the Southern Great Plains, collecting observations of trace gas mixing ratios over the ARM/SGP Central Facility. The aircraft payload included two Atmospheric Observing Systems (AOS Inc.) analyzers for continuous measurements of CO2, and a 12-flask sampler for analysis of carbon cycle gases (CO2, CO, CH4, N2O, 13CO2). The aircraft payload also includes solar/infrared radiation measurements. This research (supported by DOE ARM and TES programs) builds upon previous ARM-ACME missions. The goal of these measurements is to improve understanding of: (a) the carbon exchange of the ARM region; (b) how CO2 and associated water and energy fluxes influence radiative forcing, convective processes, and CO2 concentrations over the ARM region, and (c) how greenhouse gases are transported on continental scales.

Evolution of high duty cycle echolocation in bats

DEFF Research Database (Denmark)

Fenton, M. B.; Faure, P. A.; Ratcliffe, J. M.

2012-01-01

Duty cycle describes the relative 'on time' of a periodic signal. In bats, we argue that high duty cycle (HDC) echolocation was selected for and evolved from low duty cycle (LDC) echolocation because increasing call duty cycle enhanced the ability of echolocating bats to detect, lock onto and track...... relative to background objects and their prey. HDC echolocators are particularly sensitive to amplitude and frequency glints generated by the wings of fluttering insects. We hypothesize that narrowband/CF calls produced at high duty cycle, and combined with neurobiological specializations for processing....... In contrast, bats using HDC echolocation emit long duration, narrowband calls dominated by a single constant frequency (CF) separated by relatively short periods of silence. HDC bats separate pulse and echo in frequency by exploiting information contained in Doppler-shifted echoes arising from their movements...

Integration of SPS with utility system networks

Kaupang, B. M.

1980-01-01

The integration of Satellite Power System (SPS) power in electric utility power systems is discussed. Specifically, the nature of the power output variations from the spacecraft to the rectenna, the operational characteristics of the rectenna power, and the impacts on the electric utility system from utilizing SPS power to serve part of the system load are treated. It is concluded that if RF beam control is an acceptable method for power control, and that the site distribution of SPS rectennas do not cause a very high local penetration (40 to 50%), SPS may be integrated into electric utility system with a few negative impacts. Increased regulating duty on the conventional generation, and a potential impact on system reliability for SPS penetration in excess of about 25% appear to be two areas of concern.

2015-10-01

The Atmospheric Radiation Measurement (ARM) Program was created in 1989 with funding from the U.S. Department of Energy (DOE) to develop several highly instrumented ground stations to study cloud formation processes and their influence on radiative transfer. In 2003, the ARM Program became a national scientific user facility, known as the ARM Climate Research Facility. This scientific infrastructure provides for fixed sites, mobile facilities, an aerial facility, and a data archive available for use by scientists worldwide through the ARM Climate Research Facility—a scientific user facility. The ARM Climate Research Facility currently operates more than 300 instrument systems that provide ground-based observations of the atmospheric column. To keep ARM at the forefront of climate observations, the ARM infrastructure depends heavily on instrument scientists and engineers, also known as lead mentors. Lead mentors must have an excellent understanding of in situ and remote-sensing instrumentation theory and operation and have comprehensive knowledge of critical scale-dependent atmospheric processes. They must also possess the technical and analytical skills to develop new data retrievals that provide innovative approaches for creating research-quality data sets. The ARM Climate Research Facility is seeking the best overall qualified candidate who can fulfill lead mentor requirements in a timely manner.

The arms race control

Written in 1961, this paper presents the content of a book entitled 'The arms race control' where the author outlined the difference between disarmament and arms control, described the economic and moral role of arms race, the importance of force balance for international security. He wandered whether arms control could ensure this balance and whether nuclear balance meant force balance. Force balance then appears to be a precarious and unsteady component of international security. He commented the challenges of disarmament, recalled some arguments for a nuclear disarmament. Then he discussed what would be an arms control with or without disarmament (either nuclear or conventional)

How do octopuses use their arms?

Science.gov (United States)

Mather, J A

1998-09-01

A taxonomy of the movement patterns of the 8 flexible arms of octopuses is constructed. Components consist of movements of the arm itself, the ventral suckers and their stalks, as well as the relative position of arms and the skin web between them. Within 1 arm, combinations of components result in a variety of behaviors. At the level of all arms, 1 group of behaviors is described as postures, on the basis of the spread of all arms and the web to make a 2-dimensional surface whose position differs in the 3rd dimension. Another group of arm behaviors is actions, more or less coordinated and involving several to all arms. Arm control appears to be based on radial symmetry, relative equipotentiality of all arms, relative independence of each arm, and separability of components within the arm. The types and coordination of arm behaviors are discussed with relationship to biomechanical limits, muscle structures, and neuronal programming.

Duty hour reform in a shifting medical landscape.

Science.gov (United States)

Jena, Anupam B; Prasad, Vinay

2013-09-01

The circumstances that led to the death of Libby Zion in 1984 prompted national discussions about the impact of resident fatigue on patient outcomes. Nearly 30 years later, national duty hour reforms largely motivated by patient safety concerns have demonstrated a negligible impact of duty hour reductions on patient mortality. We suggest that the lack of an impact of duty hour reforms on patient mortality is due to a different medical landscape today than existed in 1984. Improvements in quality of care made possible by computerized order entry, automated medication checks, inpatient pharmacists, and increased resident supervision have, among other systemic changes, diminished the adverse impact that resident fatigue is able to have on patient outcomes. Given this new medical landscape, advocacy towards current and future duty hour reforms may be best justified by evidence of the impact of duty hour reform on resident wellbeing, education, and burnout.

Epistemic Duties and Failure to Understand one's Evidence

2012-08-01

Full Text Available http://dx.doi.org/10.5007/1808-1711.2012v16n1p147   The paper defends the thesis that our epistemic duty is the duty to proportion our beliefs to the evidence we possess. An inclusive view of evidenced possessed is put forward on the grounds that it makes sense of our intuitions about when it is right to say that a person ought to believe some proposition P. A second thesis is that we have no epistemic duty to adopt any particular doxastic attitudes. The apparent tension between the two theses is resolved by applying the concept of duty to belief indirectly.

CyARM: Haptic Sensing Device for Spatial Localization on Basis of Exploration by Arms

Full Text Available We introduce a new type of perception aid device based on user's exploration action, which is named as CyARM (acronym of “Cyber Arm”. The user holds this device in her/his arm, the extension of the arm is controlled by tension in wires, which are attached to her/his body according to the distance to the object. This user interface has unique characteristics that give users the illusion of an imaginary arm that extends to existing objects. The implementations of CyARM and our two experiments to investigate the efficiency and effectiveness of CyARM are described. The results show that we could confirm that CyARM can be used to recognize the presence of an object in front of the user and to measure the relative distance to the object.

Wood cross-arms coated with polyurethane resin - tests and numerical simulations

Directory of Open Access Journals (Sweden)

Ruy Alberto Correa Altafim

2006-03-01

Full Text Available Brazil's electric power utilities have commonly employed native timbers as the main material for manufacturing cross-arms for distribution lines. However, the increasingly high costs of these timbers and Brazil's new environmental laws have contributed to change this situation, spurring research on new materials for application in transmission and distribution systems. This paper discusses two reforested wood species, Pinus elliottii and Eucalyptus citriodora, coated with castor oil-based polyurethane resins, as an alternative material for distribution line cross-arms, from the standpoint of their mechanical and electrical properties and their low cost. Numerical simulations and a complete description of the entire coating process are also part of this work.

2015-07-01

Full Text Available The paper analyzes the legal provisions of the Criminal Code of the Republic of Macedonia relating to crimes against official duty. Crimes against official duty represent a group of criminal offenses that occupy a special place in criminal law. This kind of crimes is also called civil servants crimes, that is, they are defined as a violation of duty made by an official in performing his/her official duty. In this paper we will analyze all articles of the Criminal Code that regulate the group of criminal offenses against official duty. Most frequent cases of misuse of official duty are cases of misuse of official position and authorization, unprincipled operation within the service, defraud in the service, receiving a bribe, giving a bribe, unlawful mediation, disclosing an official secret, falsifying an official document and other. The paper will define the terms official and responsible person. In the context of the paper we will show the research referring to the number of registered and accused of crimes against official duty in the Republic of Macedonia in the period from 2004 to 2013.

Breach of information duties in the B2C e-commerce: adequacy of available remedies

Full Text Available

B2C e-commerce is characterised by the information asymmetry between the contracting parties. Various information duties are imposed on traders, both at the European and national level to correct this asymmetry and to ensure proper market functioning. The mandated disclosure is based on the assumption of consumers' rationality. However, developments of behavioural economics challenge this assumption. The utility of mandated disclosure in consumer contracts depends also on the remedies available to consumers in a case of breach of information duties. Those remedies are often heavily influenced by the national general private law applicable to the contractual relationship between the parties. Nevertheless, since the economics of general contract law differ importantly from principles of consumer e-commerce, various problems can be associated with the application of general law remedies to the breach of information duties in B2C contracts. The limited value of the majority of the online B2C transactions is incompatible with costly and lengthy court proceedings. Moreover, breach of information duties will often not produce enough material damage on the side of the consumer to make the remedies available. Different solutions are explored, from ADR, to the duty to advise, to non-legal mechanisms making the information easier to use for consumers throughlimiting disclosure. Finally, the right of withdrawal is analysed as an example of a specific remedy, adapted to the economics of the B2C electronic transactions, where the aims parties pursue through contracts are different than in commercial contracts, and their relationship is marked with the inequality of economic power and information asymmetry. However, the legally established cooling-off period is not free from limitations, and only a combination of various measures, including effective

Affordable Rankine Cycle Waste Heat Recovery for Heavy Duty Trucks

Energy Technology Data Exchange (ETDEWEB)

Subramanian, Swami Nathan [Eaton Corporation

2017-06-30

Nearly 30% of fuel energy is not utilized and wasted in the engine exhaust. Organic Rankine Cycle (ORC) based waste heat recovery (WHR) systems offer a promising approach on waste energy recovery and improving the efficiency of Heavy-Duty diesel engines. Major barriers in the ORC WHR system are the system cost and controversial waste heat recovery working fluids. More than 40% of the system cost is from the additional heat exchangers (recuperator, condenser and tail pipe boiler). The secondary working fluid loop designed in ORC system is either flammable or environmentally sensitive. The Eaton team investigated a novel approach to reduce the cost of implementing ORC based WHR systems to Heavy-Duty (HD) Diesel engines while utilizing safest working fluids. Affordable Rankine Cycle (ARC) concept aimed to define the next generation of waste energy recuperation with a cost optimized WHR system. ARC project used engine coolant as the working fluid. This approach reduced the need for a secondary working fluid circuit and subsequent complexity. A portion of the liquid phase engine coolant has been pressurized through a set of working fluid pumps and used to recover waste heat from the exhaust gas recirculation (EGR) and exhaust tail pipe exhaust energy. While absorbing heat, the mixture is partially vaporized but remains a wet binary mixture. The pressurized mixed-phase engine coolant mixture is then expanded through a fixed-volume ratio expander that is compatible with two-phase conditions. Heat rejection is accomplished through the engine radiator, avoiding the need for a separate condenser. The ARC system has been investigated for PACCAR’s MX-13 HD diesel engine.

Epistemic duties and failure to understand one’s evidence

Directory of Open Access Journals (Sweden)

Scott Stapleford

2012-04-01

Full Text Available The paper defends the thesis that our epistemic duty is the duty to proportion our beliefs to the evidence we possess. An inclusive view of evidenced possessed is put forward on the grounds that it makes sense of our intuitions about when it is right to say that a person ought to believe some proposition P. A second thesis is that we have no epistemic duty to adopt any particular doxastic attitudes. The apparent tension between the two theses is resolved by applying the concept of duty to belief indirectly.

Traditionally, brain-machine interfaces (BMIs) extract motor commands from a single brain to control the movements of artificial devices. Here, we introduce a Brainet that utilizes very-large-scale brain activity (VLSBA) from two (B2) or three (B3) nonhuman primates to engage in a common motor behaviour. A B2 generated 2D movements of an avatar arm where each monkey contributed equally to X and Y coordinates; or one monkey fully controlled the X-coordinate and the other controlled the Y-coordinate. A B3 produced arm movements in 3D space, while each monkey generated movements in 2D subspaces (X-Y, Y-Z, or X-Z). With long-term training we observed increased coordination of behavior, increased correlations in neuronal activity between different brains, and modifications to neuronal representation of the motor plan. Overall, performance of the Brainet improved owing to collective monkey behaviour. These results suggest that primate brains can be integrated into a Brainet, which self-adapts to achieve a common motor goal.

2016-01-01

The inter-arm systolic blood pressure difference (SBPD) is recommended to be in relation to potential cardiovascular disease (CVD). Previous studies yielded controversial results about the association between an inter-arm SBPD ≥ 10 mmHg or ≥15 mmHg and the risk of cardiovascular mortality. Therefore, we conducted this meta-analysis to investigate this association. We searched PubMed and Embase databases through December 31, 2014, and examined the references of retrieved articles to identify relevant cohort studies. We utilized Newcastle-Ottawa scale to assess the quality of included studies and calculated the summary risk estimates in a fixed/random-effect model. All data analyses were conducted using STATA version 11.0. A total of seven studies were identified. Compared with participants with an inter-arm SBPD arm SBPD ≥ 10 mmHg was 1.58 (95% CI: 1.3-1.93), and the pooled HR of cardiovascular mortality of participants with an inter-arm SBPD ≥ 15 mmHg versus those with an inter-arm SBPD arm SBPD may define a subpopulation at high risk of CVD events.

Armed conflict has a major impact on child health throughout the world. One in six children worldwide lives in an area of armed conflict and civilians are more likely to die than soldiers as a result of the conflict. In stark contrast to the effect on children, the international arms trade results in huge profits for the large corporations involved in producing arms, weapons and munitions. Armed conflict is not inevitable but is an important health issue that should be prevented.

Hello to Arms

Science.gov (United States)

2005-01-01

This image highlights the hidden spiral arms (blue) that were discovered around the nearby galaxy NGC 4625 by the ultraviolet eyes of NASA's Galaxy Evolution Explorer. The image is composed of ultraviolet and visible-light data, from the Galaxy Evolution Explorer and the California Institute of Technology's Digitized Sky Survey, respectively. Near-ultraviolet light is colored green; far-ultraviolet light is colored blue; and optical light is colored red. As the image demonstrates, the lengthy spiral arms are nearly invisible when viewed in optical light while bright in ultraviolet. This is because they are bustling with hot, newborn stars that radiate primarily ultraviolet light. The youthful arms are also very long, stretching out to a distance four times the size of the galaxy's core. They are part of the largest ultraviolet galactic disk discovered so far. Located 31 million light-years away in the constellation Canes Venatici, NGC 4625 is the closest galaxy ever seen with such a young halo of arms. It is slightly smaller than our Milky Way, both in size and mass. However, the fact that this galaxy's disk is forming stars very actively suggests that it might evolve into a more massive and mature galaxy resembling our own. The armless companion galaxy seen below NGC 4625 is called NGC 4618. Astronomers do not know why it lacks arms but speculate that it may have triggered the development of arms in NGC 4625.

Sensory-Feedback Exoskeletal Arm Controller

Science.gov (United States)

An, Bin; Massie, Thomas H.; Vayner, Vladimir

2004-01-01

An electromechanical exoskeletal arm apparatus has been designed for use in controlling a remote robotic manipulator arm. The apparatus, called a force-feedback exoskeleton arm master (F-EAM) is comfortable to wear and easy to don and doff. It provides control signals from the wearer s arm to a robot arm or a computer simulator (e.g., a virtual-reality system); it also provides force and torque feedback from sensors on the robot arm or from the computer simulator to the wearer s arm. The F-EAM enables the wearer to make the robot arm gently touch objects and finely manipulate them without exerting excessive forces. The F-EAM features a lightweight design in which the motors and gear heads that generate force and torque feedback are made smaller than they ordinarily would be: this is achieved by driving the motors to power levels greater than would ordinarily be used in order to obtain higher torques, and by providing active liquid cooling of the motors to prevent overheating at the high drive levels. The F-EAM (see figure) includes an assembly that resembles a backpack and is worn like a backpack, plus an exoskeletal arm mechanism. The FEAM has five degrees of freedom (DOFs) that correspond to those of the human arm: 1. The first DOF is that of the side-to-side rotation of the upper arm about the shoulder (rotation about axis 1). The reflected torque for this DOF is provided by motor 1 via drum 1 and a planar four-bar linkage. 2. The second DOF is that of the up-and-down rotation of the arm about the shoulder. The reflected torque for this DOF is provided by motor 2 via drum 2. 3. The third DOF is that of twisting of the upper arm about its longitudinal axis. This DOF is implemented in a cable remote-center mechanism (CRCM). The reflected torque for this DOF is provided by motor 3, which drives the upper-arm cuff and the mechanism below it. A bladder inflatable by gas or liquid is placed between the cuff and the wearer s upper arm to compensate for misalignment

Unequal-Arms Michelson Interferometers

Science.gov (United States)

Tinto, Massimo; Armstrong, J. W.

2000-01-01

Michelson interferometers allow phase measurements many orders of magnitude below the phase stability of the laser light injected into their two almost equal-length arms. If, however, the two arms are unequal, the laser fluctuations can not be removed by simply recombining the two beams. This is because the laser jitters experience different time delays in the two arms, and therefore can not cancel at the photo detector. We present here a method for achieving exact laser noise cancellation, even in an unequal-arm interferometer. The method presented in this paper requires a separate readout of the relative phase in each arm, made by interfering the returning beam in each arm with a fraction of the outgoing beam. By linearly combining the two data sets with themselves, after they have been properly time shifted, we show that it is possible to construct a new data set that is free of laser fluctuations. An application of this technique to future planned space-based laser interferometer detector3 of gravitational radiation is discussed.

A 540-[Formula: see text] Duty Controlled RSSI With Current Reusing Technique for Human Body Communication.

Science.gov (United States)

Jang, Jaeeun; Lee, Yongsu; Cho, Hyunwoo; Yoo, Hoi-Jun

2016-08-01

An ultra-low-power duty controlled received signal strength indicator (RSSI) is implemented for human body communication (HBC) in 180 nm CMOS technology under 1.5 V supply. The proposed RSSI adopted 3 following key features for low-power consumption; 1) current reusing technique (CR-RSSI) with replica bias circuit and calibration unit, 2) duty controller, and 3) reconfigurable gm-boosting LNA. The CR-RSSI utilizes stacked amplifier-rectifier-cell (AR-cell) to reuse the supply current of each blocks. As a result, the power consumption becomes 540 [Formula: see text] with +/-2 dB accuracy and 75 dB dynamic range. The replica bias circuit and calibration unit are adopted to increase the reliability of CR-RSSI. In addition, the duty controller turns off the RSSI when it is not required, and this function leads 70% power reduction. At last, the gm-boosting reconfigurable LNA can adaptively vary its noise and linearity performance with respect to input signal strength. Fro current reusing technique m this feature, we achieve 62% power reduction in the LNA. Thanks to these schemes, compared to the previous works, we can save 70% of power in RSSI and LNA.

Wi-Fi Coexistence with Duty Cycled LTE-U

Directory of Open Access Journals (Sweden)

Yimin Pang

2017-01-01

Full Text Available Coexistence of Wi-Fi and LTE-Unlicensed (LTE-U technologies has drawn significant concern in industry. In this paper, we investigate the Wi-Fi performance in the presence of duty cycle based LTE-U transmission on the same channel. More specifically, one LTE-U cell and one Wi-Fi basic service set (BSS coexist by allowing LTE-U devices to transmit their signals only in predetermined duty cycles. Wi-Fi stations, on the other hand, simply contend the shared channel using the distributed coordination function (DCF protocol without cooperation with the LTE-U system or prior knowledge about the duty cycle period or duty cycle of LTE-U transmission. We define the fairness of the above scheme as the difference between Wi-Fi performance loss ratio (considering a defined reference performance and the LTE-U duty cycle (or function of LTE-U duty cycle. Depending on the interference to noise ratio (INR being above or below −62 dbm, we classify the LTE-U interference as strong or weak and establish mathematical models accordingly. The average throughput and average service time of Wi-Fi are both formulated as functions of Wi-Fi and LTE-U system parameters using probability theory. Lastly, we use the Monte Carlo analysis to demonstrate the fairness of Wi-Fi and LTE-U air time sharing.

Environmental effects monitoring at Cat Arm Hydraulic Development, Newfoundland, Canada

International Nuclear Information System (INIS)

Hill, E.L.

1988-01-01

The Cat Arm Dam is located on a plateau of the Long Range Mountains on Newfoundland's Great Northern Peninsula, and the 127 MW unit uses a 387 m head to produce an average of 676 GWh annually. Newfoundland and Labrador Hydro is conducting an environmental effects monitoring program in Cat Arm Reservoir to evaluate environmental impacts of the project. In the addendum to the Environmental Impact Statement of 1981, the utility agreed to a number of actions to mitigate the impacts of construction on fish populations, and to monitor the effects of reservoir creation, including the following. The mercury content of fish flesh, sediments and water would be monitored, and sampling would be undertaken prior to flooding to obtain baseline data, and for at least five years after flooding. The brook trout population would be monitored at various stages in the life of the reservoir in order to detect negative changes for which mitigative strategies could be applied. Alternative spawning habitat would be provided by removing barriers on streams or creating spawning beds if the monitoring program showed that recruitment was falling, and if these methods were ineffective, a compensatory stocking program would be considered. Extensive monitoring would be undertaken of the littoral zones, primary production in the reservoir, and of a number of limnological parameters to document long term changes in the reservoir. Although of academic interest, certain unusual characteristics of the Cat Arm reservoir, such as its low pH and dark colour, reduce its utility as a predictor of changes due to reservoir formation elsewhere in Newfoundland. 15 refs., 1 fig

Performance of arm locking in LISA

International Nuclear Information System (INIS)

McKenzie, Kirk; Spero, Robert E.; Shaddock, Daniel A.

2009-01-01

For the Laser Interferometer Space Antenna (LISA) to reach its design sensitivity, the coupling of the free-running laser frequency noise to the signal readout must be reduced by more than 14 orders of magnitude. One technique employed to reduce the laser frequency noise will be arm locking, where the laser frequency is locked to the LISA arm length. In this paper we detail an implementation of arm locking. We investigate orbital effects (changing arm lengths and Doppler frequencies), the impact of errors in the Doppler knowledge that can cause pulling of the laser frequency, and the noise limit of arm locking. Laser frequency pulling is examined in two regimes: at lock acquisition and in steady state. The noise performance of arm locking is calculated with the inclusion of the dominant expected noise sources: ultrastable oscillator (clock) noise, spacecraft motion, and shot noise. We find that clock noise and spacecraft motion limit the performance of dual arm locking in the LISA science band. Studying these issues reveals that although dual arm locking [A. Sutton and D. A. Shaddock, Phys. Rev. D 78, 082001 (2008)] has advantages over single (or common) arm locking in terms of allowing high gain, it has disadvantages in both laser frequency pulling and noise performance. We address this by proposing a modification to the dual arm-locking sensor, a hybrid of common and dual arm-locking sensors. This modified dual arm-locking sensor has the laser frequency pulling characteristics and low-frequency noise coupling of common arm locking, but retains the control system advantages of dual arm locking. We present a detailed design of an arm-locking controller and perform an analysis of the expected performance when used with and without laser prestabilization. We observe that the sensor phase changes beneficially near unity-gain frequencies of the arm-locking controller, allowing a factor of 10 more gain than previously believed, without degrading stability. With a time

Evaluation of duty cycles for heavy-duty urban vehicles : final report of IEA AMF Annex 29

Heavy-duty vehicles in Europe and North America will require incylinder measures or exhaust gas after-treatment technology to control emissions and meet ever stringent emission requirements. Alternatively, manufacturers can choose clean burning alternative fuels such as natural gas. Although there are no international standards for heavy-duty vehicle chassis dynamometer testing at present, the IEA Implementing Agreements offer excellent platforms for international collaborative research. Harmonization of test methods for vehicles and fuels is one important task. This paper reported on the work of 3 laboratories that have produced emission results for complete heavy-duty vehicles. VTT Technical Research of Finland, Environment Canada and West Virginia University measured standard size urban buses driving various duty cycles on chassis dynamometers. The number of transient test cycles per laboratory varied from 6 to 16. European and North American diesel and natural gas vehicles were included in the vehicle matrix. The objective was to demonstrate how the driving cycle affects the emission performance of conventional and advanced urban buses. Several driving cycles were run on urban buses to better understand the characteristics of different duty cycles; produce a key for cross-interpretation of emission results generated with different cycles; and study the interaction between vehicle, exhaust after-treatment and fuel technologies and test procedures. Fuel consumption and exhaust emissions were measured. The results varied significantly not only by test cycle, but also by vehicle technology. In general, vehicles emissions were directly proportioned to the amount of fuel consumed, with the exception of NOx-emissions from SCR-vehicles. There was a clear difference in the emission profiles of European and North American vehicles. In Europe, fuel efficiency was emphasized, while in North America, more focus was given to regulated exhaust emissions, especially low

Clinical trial designs that include multiple treatments are currently limited to those that perform pairwise comparisons of each investigational treatment to a single control. However, there are settings, such as the recent Ebola outbreak, in which no treatment has been demonstrated to be effective; and therefore, no standard of care exists which would serve as an appropriate control. For illustrative purposes, we focused on the care of patients presenting in austere settings with critically ill 'sepsis-like' syndromes. Our approach involves a novel algorithm for comparing mortality among arms without requiring a single fixed control. The algorithm allows poorly-performing arms to be dropped during interim analyses. Consequently, the study may be completed earlier than planned. We used simulation to determine operating characteristics for the trial and to estimate the required sample size. We present a potential study design targeting a minimal effect size of a 23% relative reduction in mortality between any pair of arms. Using estimated power and spurious significance rates from the simulated scenarios, we show that such a trial would require 2550 participants. Over a range of scenarios, our study has 80 to 99% power to select the optimal treatment. Using a fixed control design, if the control arm is least efficacious, 640 subjects would be enrolled into the least efficacious arm, while our algorithm would enroll between 170 and 430. This simulation method can be easily extended to other settings or other binary outcomes. Early dropping of arms is efficient and ethical when conducting clinical trials with multiple arms.

On pandemics and the duty to care: whose duty? who cares?

Background As a number of commentators have noted, SARS exposed the vulnerabilities of our health care systems and governance structures. Health care professionals (HCPs) and hospital systems that bore the brunt of the SARS outbreak continue to struggle with the aftermath of the crisis. Indeed, HCPs – both in clinical care and in public health – were severely tested by SARS. Unprecedented demands were placed on their skills and expertise, and their personal commitment to their profession was severely tried. Many were exposed to serious risk of morbidity and mortality, as evidenced by the World Health Organization figures showing that approximately 30% of reported cases were among HCPs, some of whom died from the infection. Despite this challenge, professional codes of ethics are silent on the issue of duty to care during communicable disease outbreaks, thus providing no guidance on what is expected of HCPs or how they ought to approach their duty to care in the face of risk. Discussion In the aftermath of SARS and with the spectre of a pandemic avian influenza, it is imperative that we (re)consider the obligations of HCPs for patients with severe infectious diseases, particularly diseases that pose risks to those providing care. It is of pressing importance that organizations representing HCPs give clear indication of what standard of care is expected of their members in the event of a pandemic. In this paper, we address the issue of special obligations of HCPs during an infectious disease outbreak. We argue that there is a pressing need to clarify the rights and responsibilities of HCPs in the current context of pandemic flu preparedness, and that these rights and responsibilities ought to be codified in professional codes of ethics. Finally, we present a brief historical accounting of the treatment of the duty to care in professional health care codes of ethics. Summary An honest and critical examination of the role of HCPs during communicable disease

Nonspecific Arm Pain

Directory of Open Access Journals (Sweden)

Ali Moradi

2013-12-01

Full Text Available Nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of depression, and heightened illness concern determine a substantial percentage of the disability associated with puzzling hand and arm pains. Ergonomic modifications can help to control symptoms, but optimal health may require collaborative management incorporating psychosocial and psychological elements of illness.

Schmidt, Lena; Depper, Lena; Kerkhoff, Georg

2013-01-01

Position sense is an important proprioceptive ability. Disorders of arm position sense (APS) often occur after unilateral stroke, and are associated with a negative functional outcome. In the present study we assessed horizontal APS by measuring angular deviations from a visually defined target separately for each arm in a large group of healthy subjects. We analyzed the accuracy and instability of horizontal APS as a function of age, sex and arm. Subjects were required to specify verbally the position of their unseen arm on a 0-90° circuit by comparing the current position with the target position indicated by a LED lamp, while the arm was passively moved by the examiner. Eighty-seven healthy subjects participated in the study, ranging from 20 to 77 years, subdivided into three age groups. The results revealed that APS was not a function of age or sex, but was significantly better in the non-dominant (left) arm in absolute errors (AE) but not in constant errors (CE) across all age groups of right-handed healthy subjects. This indicates a right-hemisphere superiority for left APS in right-handers and neatly fits to the more frequent and more severe left-sided body-related deficits in patients with unilateral stroke (i.e. impaired APS in left spatial neglect, somatoparaphrenia) or in individuals with abnormalities of the right cerebral hemisphere. These clinical issues will be discussed.

Article VI of the Non-Proliferation Treaty commits each party to work towards nuclear disarmament and to negotiations to stop the nuclear arms race. All parties to the Treaty are included and a wide range of arms control and disarmament issues are covered. However the main focus at Treaty review conferences has been on nuclear disarmament by the nuclear weapon states which are party to the Treaty. This has led to bilateral United States - Soviet Union negotiations resulting in the Intermediate-range Nuclear Forces Treaty in December 1987 and the Strategic Arms Reduction Treaty (START) in July followed by unilateral arms control measures in September and October 1991.

The Department of Veterans Affairs (VA) is amending its medical regulations concerning eligibility for health care to re-establish the definitions of "active military, naval, or air service,'' "active duty,'' and "active duty for training.'' These definitions were deleted in 1996; however, we believe that all duty periods should be defined in part 17 of the Code of Federal Regulations (CFR) to ensure proper determination of eligibility for VA health care. We are also providing a more complete definition of "inactive duty training.''

Fleet average NOx emission performance of 2004 model year light-duty vehicles, light-duty trucks and medium-duty passenger vehicles

International Nuclear Information System (INIS)

2006-05-01

The On-Road Vehicle and Engine Emission Regulations came into effect on January 1, 2004. The regulations introduced more stringent national emission standards for on-road vehicles and engines, and also required that companies submit reports containing information concerning the company's fleets. This report presented a summary of the regulatory requirements relating to nitric oxide (NO x ) fleet average emissions for light-duty vehicles, light-duty trucks, and medium-duty passenger vehicles under the new regulations. The effectiveness of the Canadian fleet average NO x emission program at achieving environmental performance objectives was also evaluated. A summary of the fleet average NO x emission performance of individual companies was presented, as well as the overall Canadian fleet average of the 2004 model year based on data submitted by companies in their end of model year reports. A total of 21 companies submitted reports covering 2004 model year vehicles in 10 test groups, comprising 1,350,719 vehicles of the 2004 model year manufactured or imported for the purpose of sale in Canada. The average NO x value for the entire Canadian LDV/LDT fleet was 0.2016463 grams per mile. The average NO x values for the entire Canadian HLDT/MDPV fleet was 0.321976 grams per mile. It was concluded that the NO x values for both fleets were consistent with the environmental performance objectives of the regulations for the 2004 model year. 9 tabs

Intimate Partner Violence in the Canadian Armed Forces: The Role of Family Stress and Its Impact on Well-Being.

Science.gov (United States)

Skomorovsky, Alla; Hujaleh, Filsan; Wolejszo, Stefan

2015-07-01

Unique demands of military life (e.g., deployment) can have a significant impact on family life. Although most families cope effectively with military life stressors, some may have difficulty adjusting, experiencing marital conflicts, and violence. Evidence suggests that unmanaged occupational demands may create family stress by interfering with efforts to fulfill family duties. This study examined the effects of work-family conflict and marital satisfaction on intimate violence experienced by Canadian Armed Forces members, and the impact of such violence on their psychological well-being (N = 525). Regression analyses showed that both work-family conflict and marital satisfaction were unique and significant predictors of emotional and physical violence experienced by Canadian Armed Forces members. Moreover, bootstrapping analyses demonstrated that marital satisfaction partially mediated the relationship between work-family and family-work conflicts and intimate partner violence. The results point to the importance of examining the interrelationship between family stress and occupational stressors when exploring interpersonal violence and its psychological impact on military personnel.

Dowie, Iwan

2017-12-13

Duty of care is a fundamental aspect of nursing, and many nurses consider this to be an important part of their professional duties as a nurse. However, the legal underpinnings of duty of care are often overlooked, and, as such, nurses may be unsure about when to act if they encounter emergency situations or serious incidents, especially when they are off duty. This article examines the legal, ethical and professional aspects of duty of care, what these mean for nurses in practice, and how duty of care is intrinsically linked with standards of care and negligence. ©2017 RCN Publishing Company Ltd.

This article discusses the law surrounding breach of the duty of care in negligence. A mistake or error does not necessarily mean legal fault and negligence. Judges look at risks and benefits in determining what would have been the appropriate standard of care to be exercised in the circumstances and may decide that the defendant's conduct was reasonable. There are a number of interrelated factors which judges have to balance and these can be categorized as foreseeability of harm, magnitude of risk, burden of taking precautions, utility of the defendant's conduct and common practice.

The global conventional arms trade is worth tens of billions of dollars every year and is engaged in by every country in the world. Yet, it is often difficult to control the legal trade in conventional arms and there is a thriving illicit market, willing to arm unscrupulous regimes and nefarious non-state actors. This chapter examines the international conventional arms trade, the range of tools that have been used to control it, and challenges to these international regimes.

Robotic vision system for random bin picking with dual-arm robots

Directory of Open Access Journals (Sweden)

Kang Sangseung

2016-01-01

Full Text Available Random bin picking is one of the most challenging industrial robotics applications available. It constitutes a complicated interaction between the vision system, robot, and control system. For a packaging operation requiring a pick-and-place task, the robot system utilized should be able to perform certain functions for recognizing the applicable target object from randomized objects in a bin. In this paper, we introduce a robotic vision system for bin picking using industrial dual-arm robots. The proposed system recognizes the best object from randomized target candidates based on stereo vision, and estimates the position and orientation of the object. It then sends the result to the robot control system. The system was developed for use in the packaging process of cell phone accessories using dual-arm robots.

Filtering sensory information with XCSF: improving learning robustness and robot arm control performance.

Science.gov (United States)

Kneissler, Jan; Stalph, Patrick O; Drugowitsch, Jan; Butz, Martin V

2014-01-01

It has been shown previously that the control of a robot arm can be efficiently learned using the XCSF learning classifier system, which is a nonlinear regression system based on evolutionary computation. So far, however, the predictive knowledge about how actual motor activity changes the state of the arm system has not been exploited. In this paper, we utilize the forward velocity kinematics knowledge of XCSF to alleviate the negative effect of noisy sensors for successful learning and control. We incorporate Kalman filtering for estimating successive arm positions, iteratively combining sensory readings with XCSF-based predictions of hand position changes over time. The filtered arm position is used to improve both trajectory planning and further learning of the forward velocity kinematics. We test the approach on a simulated kinematic robot arm model. The results show that the combination can improve learning and control performance significantly. However, it also shows that variance estimates of XCSF prediction may be underestimated, in which case self-delusional spiraling effects can hinder effective learning. Thus, we introduce a heuristic parameter, which can be motivated by theory, and which limits the influence of XCSF's predictions on its own further learning input. As a result, we obtain drastic improvements in noise tolerance, allowing the system to cope with more than 10 times higher noise levels.

[Management of war orthopaedic injuries in recent armed conflicts].

2013-01-01

The extremities continue to be the most frequent sites of wounding during armed conflicts despite the change of combat tactics, soldier armour and battlefield medical support. Due to the advances in prehospital care and timely transport to the hospital, orthopaedic surgeons deal with severe and challenging injuries of the limbs. In contrast to civilian extremity trauma, the most combat-related injuries are open wounds that often have infection-related complications. Data from two recent large armed conflicts (Iraq, Afghanistan) show that extremity injuries are associated with a high complication rate, morbidity and healthcare utilization. A systematic approach that consists of sequential surgical care and good transport capabilities can reduce the complication rate of these injuries. New medical technologies have been implemented in the treatment strategy during the last decade. This article reviews the published scientific data and current opinions on combat-related extremity injuries. Key words: extremity, combat, trauma, medical support system.

To compare accuracy of blood pressure measurements using a live subject and a simulator arm, and to determine students' preferences regarding measurement. This was a crossover study comparing blood pressure measurements from a live subject and a simulator arm. Students completed an anonymous survey instrument defining opinions on ease of measurement. Fifty-seven students completed blood pressure measurements on live subjects while 72 students completed blood pressure measurements using the simulator arm. There were no significant systematic differences between the 2 measurement techniques. Systolic blood pressure measurements from a live subject arm were less likely to be within 4 mm Hg compared with measurements of a simulator arm. Diastolic blood pressure measurements were not significantly different between the 2 techniques. Accuracy of student measurement of blood pressure using a simulator arm was similar to the accuracy with a live subject. There was no difference in students' preferences regarding measurement techniques.

Borehole tool outrigger arm displacement control mechanism

Lee, A.G.

1985-01-01

As the outrigger arms of a borehole logging tool are flexed inwardly and outwardly according to the diameter of the borehole opening through which they pass, the corresponding axial displacements of the ends of the arms are controlled to determine the axial positions of the arms relative to the tool. Specifically, as the arm ends move, they are caused to rotate by a cam mechanism. The stiffness of the arms causes the arm ends to rotate in unison, and the exact positions of the arms on the tool are then controlled by the differential movements of the arm ends in the cams

To determine whether nonparetic arm force overinhibits the paretic arm in patients with chronic unilateral poststroke hemiparesis. Case-control neurophysiological and behavioral study of patients with chronic stroke. Research institution. Eighty-six referred patients were screened to enroll 9 participants (N=9) with a >6 month history of 1 unilateral ischemic infarct that resulted in arm hemiparesis with residual ability to produce 1Nm of wrist flexion torque and without contraindication to transcranial magnetic stimulation. Eight age- and handedness-matched healthy volunteers without neurologic diagnosis were studied for comparison. Not applicable. Change in interhemispheric inhibition targeting the ipsilesional primary motor cortex (M1) during nonparetic arm force. We hypothesized that interhemispheric inhibition would increase more in healthy controls than in patients with hemiparesis. Healthy age-matched controls had significantly greater increases in inhibition from their active to resting M1 than patients with stroke from their active contralesional to resting ipsilesional M1 in the same scenario (20%±7% vs -1%±4%, F1,12=6.61, P=.025). Patients with greater increases in contralesional to ipsilesional inhibition were better performers on the 9-hole peg test of paretic arm function. Our findings reveal that producing force with the nonparetic arm does not necessarily overinhibit the paretic arm. Though our study is limited in generalizability by the small sample size, we found that greater active contralesional to resting ipsilesional M1 inhibition was related with better recovery in this subset of patients with chronic poststroke.

Barr, Ronald; Collins, Laura; Nayiager, Trishana; Doring, Nancy; Kennedy, Charlene; Halton, Jacqueline; Walker, Scott; Sala, Alessandra; Webber, Colin

2011-04-01

Assessment of nutritional status in children with cancer is important but measures based on weight can be problematic at diagnosis, especially in those with advanced disease. Likewise, dual energy x-ray absorptiometry may be confounded by other radiological procedures and is not commonly available in low-income countries where most children with cancer live. Arm anthropometry is not subject to these constraints. In a study sample of 99 Canadian patients with cancer at diagnosis, mid-upper arm circumference correlated well with lean body mass as measured by dual energy x-ray absorptiometry but triceps skin fold thickness was a poor predictor of fat mass. Arm anthropometry can be a useful tool for the measurement of nutritional status in children with cancer. However, further studies, particularly in low-income countries and in children with solid tumors at diagnosis, are required to determine the full extent of its utility.

Full Text Available Employee responsibilities are prior to working rights and they are an equally important part of business ethics. There are three main parts in articulation of these responsibilities: 1. general responsibilities and duties in the process of work and in workplace, where we face the challenges of honesty, confidence, reliability, and such. 2. specific professional duties tied with profession that has heghtened responsibility of some sort, where we may find characteristic virtues connected with those professions. 3. managerial duties and responsibilities based on specific positions of managers and leaders as deciders in most important issues in business. The decisions that managers and leaders have to make have great impact to all those involved in business, and temptations they face are hard and far-reaching. The issues analyzed in the paper include work discipline, loyalty to the company, conflicts of various kinds of interests, limits of obedience, virtues accompanying various kinds of duties and obligations. .

Conflicting duties over confidentiality in Argentina and Peru.

Science.gov (United States)

Cavallo, Mercedes

2011-02-01

The medical duty of confidentiality represents a key element for the provision of reproductive and sexual health services. In some Latin American countries, such as Argentina and Peru, the legal systems impose—or are interpreted as imposing—on health professionals the duty of confidentiality, but also the duty to report the commission of a public order offense that they know about owing to the practicing of their profession. In these countries, the conflicting duties and the criminalization of abortion cause severe public health and human rights problems when health professionals assist their patients for post-abortion treatment. Typically, patients are deterred from seeking prompt medical care, and their privacy, autonomy, and dignity are violated. A 2010 ruling from the Supreme Court of Argentina and a 2004 ruling from the Inter-American Court of Human Rights emerge as important instruments that grant a more adequate protection of medical confidentiality. © 2010 International Federation of Gynecology and Obstetrics.

THE EVOLUTION AND COMPLEXITY OF DIRECTORS' DUTY OF CARE

Directory of Open Access Journals (Sweden)

Adina Ponta

2015-11-01

Full Text Available The duty of care, which sets the standard of conduct of a „good director” is currently governed by the Romanian Companies Act and the Civil Code. The corroboration of the two legal acts is challenging, the paper in hand aims at a comparative view of the legal norms and at the appraisal of the content of this fiduciary duty in the modern context of the competitive economy. The nature of this fiduciary duty and the cases when it can be defied according to the Romanian Law are discussed in terms of the literature and the case law that inspired the legislator. By creating parallels between the content of the agency and the traditional characters of the director's office, mainly tagged with legal prerogatives, the study will reveal the importance of the fiduciary characters of the director’s function. The conclusions will catch the effects of standardizing the substantive exercise of the duty of care and the importance of defining the fiduciary character of directors’ duties, both with respect to case law and as well for healthy business relationships.

Arms races between and within species.

Science.gov (United States)

Dawkins, R; Krebs, J R

1979-09-21

An adaptation in one lineage (e.g. predators) may change the selection pressure on another lineage (e.g. prey), giving rise to a counter-adaptation. If this occurs reciprocally, an unstable runaway escalation or 'arms race' may result. We discuss various factors which might give one side an advantage in an arms race. For example, a lineage under strong selection may out-evolve a weakly selected one (' the life-dinner principle'). We then classify arms races in two independent ways. They may be symmetric or asymmetric, and they may be interspecific or intraspecific. Our example of an asymmetric interspecific arms race is that between brood parasites and their hosts. The arms race concept may help to reduce the mystery of why cuckoo hosts are so good at detecting cuckoo eggs, but so bad at detecting cuckoo nestlings. The evolutionary contest between queen and worker ants over relative parental investment is a good example of an intraspecific asymmetric arms race. Such cases raise special problems because the participants share the same gene pool. Interspecific symmetric arms races are unlikely to be important, because competitors tend to diverge rather than escalate competitive adaptations. Intraspecific symmetric arms races, exemplified by adaptations for male-male competition, may underlie Cope's Rule and even the extinction of lineages. Finally we consider ways in which arms races can end. One lineage may drive the other to extinction; one may reach an optimum, thereby preventing the other from doing so; a particularly interesting possibility, exemplified by flower-bee coevolution, is that both sides may reach a mutual local optimum; lastly, arms races may have no stable and but may cycle continuously. We do not wish necessarily to suggest that all, or even most, evolutionary change results from arms races, but we do suggest that the arms race concept may help to resolve three long-standing questions in evolutionary theory.

Domestic politics, citizen activism, and U.S. nuclear arms control policy

International Nuclear Information System (INIS)

Knopf, J.W.

1991-01-01

The author seeks to ascertain whether and how citizens' movements concerning nuclear arms control and disarmament affect US arms control policy. The author employs a comparative case study methodology. He examines cases of the Eisenhower and Kennedy Administrations during the period of protest against nuclear testing, and the Reagan Administration during the nuclear weapons freeze campaign and the subsequent campaign for a comprehensive test ban. He hows there are four mechanisms through which public advocacy efforts can influence arms control policy, identifies the conditions under which each can be effective, and details the type of impact each mechanism has. Domestic activism interacts with broader public opinion in a way that creates electoral pressure; with elite-level debates in a way that removes a consensus behind presidential policy or changes the winning coalition in Congress; with bureaucratic politics, by generating ideas that have utility for some agents within the Executive; or with the public diplomacy of foreign governments, especially the Soviet Union. Citizens' movements had an impact on policy in each of the cases studied. The type and extent of impact, and the mechanisms involved in giving activism influence, are different for each case

This study aims to identify general principles in the organization of these movements. Video records of the movements of Octopus vulgaris performing the task of reaching toward a target were studied. The octopus extends its arm toward the target by a wave-like propagation of a bend that travels from the base of the arm toward the tip. Similar bend propagation is seen in other octopus arm movements, such as locomotion and searching. The kinematics (position and velocity) of the midpoint of the bend in three-dimensional space were extracted using the direct linear transformation algorithm. This showed that the bend tends to move within a single linear plane in a simple, slightly curved path connecting the center of the animal's body with the target location. Approximately 70% of the reaching movements demonstrated a stereotyped tangential velocity profile. An invariant profile was observed when movements were normalized for velocity and distance. Two arms, extended together in the same behavioral context, demonstrated identical velocity profiles. The stereotyped features of the movements were also observed in spontaneous arm extensions (not toward an external target). The simple and stereotypic appearance of the bend trajectory suggests that the position of the bend in space and time is the controlled variable. We propose that this strategy reduces the immense redundancy of the octopus arm movements and hence simplifies motor control.

The patient's duty to adhere to prescribed treatment: an ethical analysis.

Science.gov (United States)

Resnik, David B

2005-04-01

This article examines the ethical basis for the patient's duty to adhere to the physician's treatment prescriptions. The article argues that patients have a moral duty to adhere to the physician's treatment prescriptions, once they have accepted treatment. Since patients still retain the right to refuse medical treatment, their duty to adhere to treatment prescriptions is a prima facie duty, which can be overridden by their other ethical duties. However, patients do not have the right to refuse to adhere to treatment prescriptions if their non-adherence poses a significant threat to other people. This paper also discusses the use of written agreements between physicians and patients as a strategy for promoting patient adherence.

The regulatory framework concerning the new excise duty appears as complex and unfinished, raising more questions than providing answers. The duty will entail a significant expense item for the businesses liable to register and it is therefore important to have an overview of how the regulatory framework should be understood.

Full Text Available Background: Duty service of gyecology and obstetrics in Slovenia is organized on the regional basis and consists of ten regional hospitals, two hospitals for gynecology and obstetrics and two university clinical centres. Methods: Heads of hospitals where duty service is performed, have answered the questionnaires about the doctors who perform duty service. Results: Specialists and trainees in gynecology and obstetrics perform duty service on 21 posts and on 6 on-call posts. In Slovenia there are 287 active specialists in gynecology and obstetrics. 139 (48.4% among them are active on the primary level (outpatient clinics and 148 (51.6% in the hospitals and both clinical centres. Among hospital gynecologists and obstetricians 54 (36.5% of them are older than 55 years. Conclusions: Duty service of gyecology and obstetrics in Slovenia does not meet legislation criteria regard- ing doctors’ work time. Adequate changes for increasing the number of available doctors for duty service are proposed.

Kansas Consortium Plug-in Hybrid Medium Duty

Energy Technology Data Exchange (ETDEWEB)

2012-03-31

On September 30, 2008, the US Department of Energy (DoE), issued a cooperative agreement award, DE-FC26-08NT01914, to the Metropolitan Energy Center (MEC), for a project known as “Kansas Consortium Plug-in Hybrid Medium Duty Certification” project. The cooperative agreement was awarded pursuant to H15915 in reference to H. R. 2764 Congressionally Directed Projects. The original agreement provided funding for The Consortium to implement the established project objectives as follows: (1) to understand the current state of the development of a test protocol for PHEV configurations; (2) to work with industry stakeholders to recommend a medium duty vehicle test protocol; (3) to utilize the Phase 1 Eaton PHEV F550 Chassis or other appropriate PHEV configurations to conduct emissions testing; (4) and to make an industry PHEV certification test protocol recommendation for medium duty trucks. Subsequent amendments to the initial agreement were made, the most significant being a revised Scope of Project Objectives (SOPO) that did not address actual field data since it was not available as originally expected. This project was mated by DOE with a parallel project award given to the South Coast Air Quality Management District (SCAQMD) in California. The SCAQMD project involved designing, building and testing of five medium duty plug-in hybrid electric trucks. SCAQMD had contracted with the Electric Power Research Institute (EPRI) to manage the project. EPRI provided the required match to the federal grant funds to both the SCAQMD project and the Kansas Consortium project. The rational for linking the two projects was that the data derived from the SCAQMD project could be used to validate the protocols developed by the Kansas Consortium team. At the same time, the consortium team would be a useful resource to SCAQMD in designating their test procedures for emissions and operating parameters and determining vehicle mileage. The years between award of the cooperative

Sensor-based whole-arm obstacle avoidance for unstructured environments

International Nuclear Information System (INIS)

Wintenberg, AL.; Butler, P.L.; Babcock, S.M.; Ericson, M.N.; Britton, C.L. Jr.; Hamel, W.R.

1992-01-01

Whole-arm obstacle avoidance is needed for a variety of robotic applications in the Environmental Restoration and Waste Management (ER ampersand WM) Program. Typical industrial applications of robotics involve well-defined work spaces, allowing a predetermined knowledge of collision-free paths for manipulator motion. In the unstructured or poorly defined hazardous environments of the ER ampersand WM program, the potential for significant problems resulting from collisions between manipulators and the environment in which they are utilized is great. A sensing system under development, which will provide protection against such collisions, is described in this paper

Octopus-inspired multi-arm robotic swimming.

Science.gov (United States)

Sfakiotakis, M; Kazakidi, A; Tsakiris, D P

2015-05-13

The outstanding locomotor and manipulation characteristics of the octopus have recently inspired the development, by our group, of multi-functional robotic swimmers, featuring both manipulation and locomotion capabilities, which could be of significant engineering interest in underwater applications. During its little-studied arm-swimming behavior, as opposed to the better known jetting via the siphon, the animal appears to generate considerable propulsive thrust and rapid acceleration, predominantly employing movements of its arms. In this work, we capture the fundamental characteristics of the corresponding complex pattern of arm motion by a sculling profile, involving a fast power stroke and a slow recovery stroke. We investigate the propulsive capabilities of a multi-arm robotic system under various swimming gaits, namely patterns of arm coordination, which achieve the generation of forward, as well as backward, propulsion and turning. A lumped-element model of the robotic swimmer, which considers arm compliance and the interaction with the aquatic environment, was used to study the characteristics of these gaits, the effect of various kinematic parameters on propulsion, and the generation of complex trajectories. This investigation focuses on relatively high-stiffness arms. Experiments employing a compliant-body robotic prototype swimmer with eight compliant arms, all made of polyurethane, inside a water tank, successfully demonstrated this novel mode of underwater propulsion. Speeds of up to 0.26 body lengths per second (approximately 100 mm s(-1)), and propulsive forces of up to 3.5 N were achieved, with a non-dimensional cost of transport of 1.42 with all eight arms and of 0.9 with only two active arms. The experiments confirmed the computational results and verified the multi-arm maneuverability and simultaneous object grasping capability of such systems.

Perceived utility of emotion: the structure and construct validity of the Perceived Affect Utility Scale in a cross-ethnic sample.

Science.gov (United States)

Chow, Philip I; Berenbaum, Howard

2012-01-01

This study introduces a new measure of the perceived utility of emotion, which is the degree to which emotions are perceived to be useful in achieving goals. In this study, we administered this new measure, the Perceived Affect Utility Scale (PAUSe), to a sample of 142 European American and 156 East Asian American college students. Confirmatory factor analyses provided support for a new, culturally informed parsing of emotion and for perceived utility of emotion to be distinguishable from ideal affect, a related but separate construct. Next, we explored the potential importance of perceived utility of emotion in cultural research. Through path analyses, we found that: (a) culturally relevant variables (e.g., independence) played a mediating role in the link between ethnic group and perceived utility of emotion; and (b) perceived utility of emotion played a mediating role in the link between culturally relevant variables and ideal affect. In particular, perceived utility of self-centered emotions (e.g., pride) was found to be associated with independence and ideal affect of those same emotions. In contrast, perceived utility of other-centered emotions (e.g., appreciation) was found to be associated with interdependence, dutifulness/self-discipline, and ideal affect of those same emotions. Implications for perceived utility of emotion in understanding cultural factors are discussed.

Screw expander for light duty diesel engines

Science.gov (United States)

1983-01-01

Preliminary selection and sizing of a positive displacement screw compressor-expander subsystem for a light-duty adiabatic diesel engine; development of a mathematical model to describe overall efficiencies for the screw compressor and expander; simulation of operation to establish overall efficiency for a range of design parameters and at given engine operating points; simulation to establish potential net power output at light-duty diesel operating points; analytical determination of mass moments of inertia for the rotors and inertia of the compressor-expander subsystem; and preparation of engineering layout drawings of the compressor and expander are discussed. As a result of this work, it was concluded that the screw compressor and expander designed for light-duty diesel engine applications are viable alternatives to turbo-compound systems, with acceptable efficiencies for both units, and only a moderate effect on the transient response.

The duty to do the best for one's patient.

Science.gov (United States)

Crisp, Roger

2015-03-01

This paper is a discussion of the duty of doctors to do what is best for their patients. What is required by this duty is shown to depend on the circumstances, including any financial constraints on the doctor. The duty to do the best is a duty of benevolence, and this virtue itself has to be understood as bounded by other virtues, including justice and professional responsibility. An Aristotelian account of medical benevolence is developed, and the issues of supererogation and individual judgement are discussed within this framework. The paper ends with the claim that the patient-centred conception of benevolence defended in the paper is in line with consequentialist and deontological ethical traditions.

Fort, Emmanuel; Chiron, Mireille; Davezies, Philippe; Bergeret, Alain; Charbotel, Barbara

2013-01-01

A case-control study was carried out to identify driving behaviors associated with the risk of on-duty road accident and to compare driving behaviors according to the type of journey (on duty, commuting, and private) for on-duty road accident victims. Cases were recruited from the Rhône Road Trauma Registry between January 2004 and October 2005 and were on duty at the time of the accident. Control subjects were recruited from the electoral rolls of the case subjects' constituencies of residence. Cases' and controls' driving behavior data were collected by self-administered questionnaire. A logistic regression was performed to identify behavioral risk factors for on-duty road accidents, taking into account age, sex, place of residence, road accident risk exposure, socio-occupational category, and type of road user. A second analysis focused specifically on the case subjects, comparing their self-assessed usual behaviors according to the type of journey. Significant factors for multivariate analysis of on-duty road accidents were female gender, history of on-duty road accidents during the previous 10 years, severe time pressure at work, and driving a vehicle not belonging to the driver. On-duty road accident victims reported behavioral risk factors more frequently in relation to driving for work than driving for private reasons or commuting: nonsystematic seat belt use, cell phone use at least once daily while driving, and history of accidents with injury during the previous 10 years. This study provides knowledge on behavioral risk factors for on-duty road accidents and differences in behavior according to the type of journey for subjects who have been on-duty road accident victims. These results will be useful for the design of on-duty road risk prevention.

Clinical negligence and duty of candour.

Science.gov (United States)

Shekar, Vinita; Singh, Mark; Shekar, Kishore; Brennan, Peter

2011-12-01

The Department of Health is considering imposing a legal duty of candour on health care providers to ensure that an apology and explanation are given to patients when errors occur during medical treatment. This aims to improve quality of care and reduce adverse events during medical treatment. We present the current system of clinical negligence and the future of medical ethics. We discuss relevant cases with regard to duty of candour, and highlight the existence of serious imbalances in which patients' rights and corresponding ethical duties of professionals predominate over the responsibilities of patients themselves. It is known that most adverse events arise because of multiple factors for which no individual should be blamed. To improve healthcare services there is a need for a system in which lessons can be learnt from mistakes, and services can be improved in the interest of patient safety, and for transparency in the broad principles on which the decisions are based within which clinical performance is supervised and monitored.

Whole-arm obstacle avoidance system conceptual design

International Nuclear Information System (INIS)

Wintenberg, A.L.; Butler, P.L.; Babcock, S.M.; Ericson, M.N.; Britton, C.L. Jr.

1993-04-01

Whole-arm obstacle avoidance is needed for a variety of robotic applications in the Environmental Restoration and Waste Management (ER ampersand WM) Program. Typical industrial applications of robotics involve well-defined workspaces, allowing a predetermined knowledge of collision-free paths for manipulator motion. In the unstructured or poorly defined hazardous environments of the ER ampersand WM Program, the potential for significant problems resulting from collisions between manipulators and the environment in which they are utilized is great. The conceptual design for a sensing system that will provide protection against such collisions is described herein. The whole-arm obstacle avoidance system consists of a set of sensor ''bracelets,'' which cover the surface area of the manipulator links to the maximum extent practical, and a host processor. The host processor accepts commands from the robot control system, controls the operation of the sensors, manipulates data received from the bracelets, and makes the data available to the manipulator control system. The bracelets consist of a subset of the sensors, associated sensor interface electronics, and a bracelet interface. Redundant communications links between the host processor and the bracelets are provided, allowing single-point failure protection. The system allows reporting of 8-bit data from up to 1000 sensors at a minimum of 50 Hz. While the initial prototype implementation of the system utilizes capacitance proximity sensor, the system concept allows multiple types of sensors. These sensors are uniquely addressable, allowing remote calibration, thresholding at the bracelet, and correlation of a sensor measurement with the associated sensor and its location on the manipulator. Variable resolution allows high-speed, single-bit sensing as well as lower-speed higher-resolution sensing, which is necessary for sensor calibration and potentially useful in control

New Design Concept for an Excavator Arms by Using Composite Material

Science.gov (United States)

Solazzi, L.; Assi, A.; Ceresoli, F.

2018-06-01

The purpose of the present paper is to lightweight design an excavator arms, by using a different materials and in particular composite material. Specifically, the research is based on the study of a commercial excavator, by determining its geometry and analyzing the load conditions to which it is exposed. These are determined in relation to either the load diagram of the machine or the possible utilities of the excavator, such as the rotation of the machine. The materials used and implemented in the different analytical and numerical elaborations are classic construction steel S 355 (UNI EN 10025-3), high-resistance steel S 890 (UNI EN 10025-6), aluminum Al 6063 T6 (UNI EN 573-3) and the composite material made by carbon fiber and epoxy resin. The adopted constraints for the design of new arms with different materials, non-conventional for these applications, are numerous. The new solutions must present a safety factor either with respect to the yield tensile strength or to the critical load of buckling greater than or equal to the one determined for the excavator in its original geometrical conformation. Another criterion, which has heavily conditioned the geometry of the arms, was given by the fact that the developed solutions must present a very similar value of the maximum displacement in the different load conditions analyzed. A new geometry for arms made by composite material was developed. It was an elliptical conic section, instead of the classic rectangular section, in order to use the filament winding technological process. As for the adoption of the composite material, we focused on the study and the design of this material as long as the interaction with the extremities (made of aluminum) which are interfaced either with the link between the arms or with the elements of the hydraulic plant which serves for the arms movement. From the results developed, it emerges that the solution developed by adopting composite materials is the one that permits the

On-road emissions of light-duty vehicles in europe.

Science.gov (United States)

Weiss, Martin; Bonnel, Pierre; Hummel, Rudolf; Provenza, Alessio; Manfredi, Urbano

2011-10-01

For obtaining type approval in the European Union, light-duty vehicles have to comply with emission limits during standardized laboratory emissions testing. Although emission limits have become more stringent in past decades, light-duty vehicles remain an important source of nitrogen oxides and carbon monoxide emissions in Europe. Furthermore, persisting air quality problems in many urban areas suggest that laboratory emissions testing may not accurately capture the on-road emissions of light-duty vehicles. To address this issue, we conduct the first comprehensive on-road emissions test of light-duty vehicles with state-of-the-art Portable Emission Measurement Systems. We find that nitrogen oxides emissions of gasoline vehicles as well as carbon monoxide and total hydrocarbon emissions of both diesel and gasoline vehicles generally remain below the respective emission limits. By contrast, nitrogen oxides emissions of diesel vehicles (0.93 ± 0.39 grams per kilometer [g/km]), including modern Euro 5 diesel vehicles (0.62 ± 0.19 g/km), exceed emission limits by 320 ± 90%. On-road carbon dioxide emissions surpass laboratory emission levels by 21 ± 9%, suggesting that the current laboratory emissions testing fails to accurately capture the on-road emissions of light-duty vehicles. Our findings provide the empirical foundation for the European Commission to establish a complementary emissions test procedure for light-duty vehicles. This procedure could be implemented together with more stringent Euro 6 emission limits in 2014. The envisaged measures should improve urban air quality and provide incentive for innovation in the automotive industry.

Performance concerns for high duty fuel cycle

International Nuclear Information System (INIS)

Esposito, V.J.; Gutierrez, J.E.

1999-01-01

One of the goals of the nuclear industry is to achieve economic performance such that nuclear power plants are competitive in a de-regulated market. The manner in which nuclear fuel is designed and operated lies at the heart of economic viability. In this sense reliability, operating flexibility and low costs are the three major requirements of the NPP today. The translation of these three requirements to the design is part of our work. The challenge today is to produce a fuel design which will operate with long operating cycles, high discharge burnup, power up-rating and while still maintaining all design and safety margins. European Fuel Group (EFG) understands that to achieve the required performance high duty/energy fuel designs are needed. The concerns for high duty design includes, among other items, core design methods, advanced Safety Analysis methodologies, performance models, advanced material and operational strategies. The operational aspects require the trade-off and evaluation of various parameters including coolant chemistry control, material corrosion, boiling duty, boron level impacts, etc. In this environment MAEF is the design that EFG is now offering based on ZIRLO alloy and a robust skeleton. This new design is able to achieve 70 GWd/tU and Lead Test Programs are being executed to demonstrate this capability. A number of performance issues which have been a concern with current designs have been resolved such as cladding corrosion and incomplete RCCA insertion (IRI). As the core duty becomes more aggressive other new issues need to be addressed such as Axial Offset Anomaly. These new issues are being addressed by combination of the new design in concert with advanced methodologies to meet the demanding needs of NPP. The ability and strategy to meet high duty core requirements, flexibility of operation and maintain acceptable balance of all technical issues is the discussion in this paper. (authors)

Clinical effectiveness of decongestive treatments on excess arm volume and patient-centered outcomes in women with early breast cancer-related arm lymphedema: a systematic review

Science.gov (United States)

Jeffs, Eunice; Ream, Emma; Taylor, Cath; Bick, Debra

2018-01-01

ABSTRACT Objective: To identify the effect of decongestive lymphedema treatment on excess arm volume or patient-centered outcomes in women presenting within either 12 months or a mean nine months of developing arm lymphedema following breast cancer treatment. Introduction: Lymphedema is a common consequence of breast cancer treatment requiring life-long treatment to reduce symptoms and prevent complications. Currently, evidence to inform the optimal decongestive lymphedema treatment package is lacking. Inclusion criteria: The review included studies on women who received lymphedema treatment within either 12 months or a mean of nine months of developing unilateral breast cancer-related arm lymphedema. The intervention was any decongestive lymphedema treatment delivered with the purpose of reducing arm lymphedema, compared to another form of lymphedema treatment (whether self or practitioner-administered), placebo or no treatment. The clinical outcome was excess arm volume; patient-centered outcomes were health-related quality of life, arm heaviness, arm function, patient-perceived benefit and satisfaction with treatment. Experimental study designs were eligible, including randomized and non-randomized controlled trials, quasi-experimental, prospective and retrospective before and after studies were considered. Methods: A three-step search strategy was utilized to find published and unpublished studies. The search identified studies published from the inception of each database to July 6, 2016.

Spiral-arm instability: giant clump formation via fragmentation of a galactic spiral arm

Science.gov (United States)

Inoue, Shigeki; Yoshida, Naoki

2018-03-01

Fragmentation of a spiral arm is thought to drive the formation of giant clumps in galaxies. Using linear perturbation analysis for self-gravitating spiral arms, we derive an instability parameter and define the conditions for clump formation. We extend our analysis to multicomponent systems that consist of gas and stars in an external potential. We then perform numerical simulations of isolated disc galaxies with isothermal gas, and compare the results with the prediction of our analytic model. Our model describes accurately the evolution of the spiral arms in our simulations, even when spiral arms dynamically interact with one another. We show that most of the giant clumps formed in the simulated disc galaxies satisfy the instability condition. The clump masses predicted by our model are in agreement with the simulation results, but the growth time-scale of unstable perturbations is overestimated by a factor of a few. We also apply our instability analysis to derive scaling relations of clump properties. The expected scaling relation between the clump size, velocity dispersion, and circular velocity is slightly different from that given by the Toomre instability analyses, but neither is inconsistent with currently available observations. We argue that the spiral-arm instability is a viable formation mechanism of giant clumps in gas-rich disc galaxies.

A Non-linear Model for Predicting Tip Position of a Pliable Robot Arm Segment Using Bending Sensor Data

Directory of Open Access Journals (Sweden)

Elizabeth I. SKLAR

2016-04-01

Full Text Available Using pliable materials for the construction of robot bodies presents new and interesting challenges for the robotics community. Within the EU project entitled STIFFness controllable Flexible & Learnable manipulator for surgical Operations (STIFF-FLOP, a bendable, segmented robot arm has been developed. The exterior of the arm is composed of a soft material (silicone, encasing an internal structure that contains air-chamber actuators and a variety of sensors for monitoring applied force, position and shape of the arm as it bends. Due to the physical characteristics of the arm, a proper model of robot kinematics and dynamics is difficult to infer from the sensor data. Here we propose a non-linear approach to predicting the robot arm posture, by training a feed-forward neural network with a structured series of pressures values applied to the arm's actuators. The model is developed across a set of seven different experiments. Because the STIFF-FLOP arm is intended for use in surgical procedures, traditional methods for position estimation (based on visual information or electromagnetic tracking will not be possible to implement. Thus the ability to estimate pose based on data from a custom fiber-optic bending sensor and accompanying model is a valuable contribution. Results are presented which demonstrate the utility of our non-linear modelling approach across a range of data collection procedures.

Poly(glycolide multi-arm star polymers: Improved solubility via limited arm length

Directory of Open Access Journals (Sweden)

Florian K. Wolf

2010-06-01

Full Text Available Due to the low solubility of poly(glycolic acid (PGA, its use is generally limited to the synthesis of random copolyesters with other hydroxy acids, such as lactic acid, or to applications that permit direct processing from the polymer melt. Insolubility is generally observed for PGA when the degree of polymerization exceeds 20. Here we present a strategy that allows the preparation of PGA-based multi-arm structures which significantly exceed the molecular weight of processable oligomeric linear PGA (<1000 g/mol. This was achieved by the use of a multifunctional hyperbranched polyglycerol (PG macroinitiator and the tin(II-2-ethylhexanoate catalyzed ring-opening polymerization of glycolide in the melt. With this strategy it is possible to combine high molecular weight with good molecular weight control (up to 16,000 g/mol, PDI = 1.4–1.7, resulting in PGA multi-arm star block copolymers containing more than 90 wt % GA. The successful linkage of PGA arms and PG core via this core first/grafting from strategy was confirmed by detailed NMR and SEC characterization. Various PG/glycolide ratios were employed to vary the length of the PGA arms. Besides fluorinated solvents, the materials were soluble in DMF and DMSO up to an average arm length of 12 glycolic acid units. Reduction in the Tg and the melting temperature compared to the homopolymer PGA should lead to simplified processing conditions. The findings contribute to broadening the range of biomedical applications of PGA.

An ARM data-oriented diagnostics package to evaluate the climate model simulation

Science.gov (United States)

Zhang, C.; Xie, S.

2016-12-01

A set of diagnostics that utilize long-term high frequency measurements from the DOE Atmospheric Radiation Measurement (ARM) program is developed for evaluating the regional simulation of clouds, radiation and precipitation in climate models. The diagnostics results are computed and visualized automatically in a python-based package that aims to serve as an easy entry point for evaluating climate simulations using the ARM data, as well as the CMIP5 multi-model simulations. Basic performance metrics are computed to measure the accuracy of mean state and variability of simulated regional climate. The evaluated physical quantities include vertical profiles of clouds, temperature, relative humidity, cloud liquid water path, total column water vapor, precipitation, sensible and latent heat fluxes, radiative fluxes, aerosol and cloud microphysical properties. Process-oriented diagnostics focusing on individual cloud and precipitation-related phenomena are developed for the evaluation and development of specific model physical parameterizations. Application of the ARM diagnostics package will be presented in the AGU session. This work is performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344, IM release number is: LLNL-ABS-698645.

de Fátima Guerreiro Godoy, Maria

2010-01-01

Full Text Available The aim of this study was to evaluate the reduction in volume of arm lymphedema secondary to breast cancer therapy utilizing an exercise facilitating device. Twenty-one women with arm lymphedema resulting from the surgical and radiotherapeutic treatment of breast cancer were randomly selected. Evaluation was made by water-displacement volumetry before and after each session. The patients were submitted to a series of active exercises using a facilitating device for four 12-minute sessions with intervals of 3 minutes between sessions in the sitting position with alignment of the spinal column. The lymphedematous arm was maintained under compression using a cotton-polyester sleeve. The active exercising device used was a mobile flexion bar fixed on a metal base at a height of 30 cm from the tabletop and at a distance of 10 cm from the patient’s body. The paired t-test was utilized for statistical analysis with an alpha error of 5% (p-value ≤0.05 being considered significant. The initial mean volume of the arms was 2,089.9 and the final volume was 2,023.0 mL with a mean loss of 66.9 mL (p-value <0.001. In conclusion, active exercises utilizing facilitating devices can contribute to a reduction in size of lymphedematous limbs.

A workplace modified duty program for employees in an oncology center.

Science.gov (United States)

Soteriades, Elpidoforos S

2017-01-01

Workplace modified duty programs may provide reasonable accommodations to employees who have partial temporary job disability and could work on duty accommodations until they fully recover. However, little is known about the implementation barriers and effectiveness of such programs. This study is aimed at evaluating the implementation of a modified duty program for employees in an oncology center. A modified duty program for employees working at the Bank of Cyprus Oncology Center, a non profit organization with 200 employees located in the Republic of Cyprus was evaluated based on the health records of the occupational medicine department. Employees' participation in the program was 3%. A total of 12 employees participated (6 each year). The participants were all women and the mean participation period was 21.6 days (range 10 - 65 days). The two most frequent reasons for a modified duty assignment were pregnancy and back pain. Employees were assigned either on limited duties or on a combination of limited duties and reduced work hours. Employees reported being very satisfied with their participation based on a follow-up narrative oral assessment. The small participation rate does not allow for advanced statistical analyses. Further studies from larger organizations are urgently needed to evaluate the effectiveness of modified duty programs. The development of a legal framework for such modified duty programs in Cyprus as well as internationally may promote their implementation in order to facilitate the effective management of temporary partial job disability for the benefit of both employees and businesses.

Emissions from Medium-Duty Conventional and Diesel-Electric Hybrid Vehicles; NREL (National Renewable Energy Laboratory)

Energy Technology Data Exchange (ETDEWEB)

Ragatz, A.; Duran, A.; Thornton, M.; Walkowicz, K.

2014-04-02

This presentation discusses the results of emissions testing for medium-duty conventional and diesel-electric hybrid vehicles. Testing was based on a field evaluation approach that utilized the Fleet DNA drive cycle database and NREL’s Renewable Fuels and Lubricants (ReFUEL) Laboratory chassis dynamometer. Vehicles tested included parcel delivery (Class 6 step vans), beverage delivery (Class 8 tractors), and parcel delivery (Class 7 box trucks) vehicles, all with intended service class medium/heavy heavy-duty diesel (MHDD).
Results for fuel economy and tailpipe NOx emissions included: diesel hybrid electric vehicles showed an average fuel economy advantage on identified test cycles: Class 6 Step Vans: 26%; Class 7 Box Trucks: 24.7%; Class 8 Tractors: 17.3%. Vehicle miles traveled is an important factor in determining total petroleum and CO2 displacement. Higher NOx emissions were observed over some test cycles: highly drive cycle dependent; engine-out differences may result from different engine operating point; and selective catalyst reduction temperature may play a role, but does not explain the whole story.

The fiduciary duties of healthcare directors in the "zone of insolvency".

Science.gov (United States)

Peregrine, Michael W; Schwartz, James R; Burgdorfer, James E; Gordon, David C

2002-01-01

Directors of healthcare organizations normally owe fiduciary duties to their shareholders or, in the case of nonprofits, to the charitable mission of the organization. As an organization descends to bankruptcy, however, the board's duties may shift. At some point, the board may be imposed with different and often conflicting obligations to the corporate enterprise as a whole, with a primary criterion being the interests of creditors. In this article, the authors analyze the murky areas of the Zone and give guidance as to when the board's duty may shift-and as to how directors should proceed both in determining their duties and in working to fulfill them.

Arm Volumetry Versus Upper Extremity Lymphedema Index: Validity of Upper Extremity Lymphedema Index for Body-Type Corrected Arm Volume Evaluation.

Science.gov (United States)

Yamamoto, Nana; Yamamoto, Takumi; Hayashi, Nobuko; Hayashi, Akitatsu; Iida, Takuya; Koshima, Isao

2016-06-01

Volumetry, measurement of extremity volume, is a commonly used method for upper extremity lymphedema (UEL) evaluation. However, comparison between different patients with different physiques is difficult with volumetry, because body-type difference greatly affects arm volume. Seventy arms of 35 participants who had no history of arm edema or breast cancer were evaluated. Arm volume was calculated using a summed truncated cone model, and UEL index was calculated using circumferences and body mass index (BMI). Examinees' BMI was classified into 3 groups, namely, low BMI (BMI, 25 kg/m). Arm volume and UEL index were compared with corresponding BMI groups. Mean (SD) arm volume was 1090.9 (205.5) mL, and UEL index 96.9 (5.6). There were significant differences in arm volume between BMI groups [low BMI vs middle BMI vs high BMI, 945.2 (107.4) vs 1045.2 (87.5) vs 1443.1 (244.4) mL, P 0.5]. Arm volume significantly increased with increase of BMI, whereas UEL index stayed constant regardless of BMI. Upper extremity lymphedema index would allow better body-type corrected arm volume evaluation compared with arm volumetry.

Expanding the scope of practice for radiology managers: radiation safety duties.

Science.gov (United States)

Orders, Amy B; Wright, Donna

2003-01-01

In addition to financial responsibilities and patient care duties, many medical facilities also expect radiology department managers to wear "safety" hats and complete fundamental quality control/quality assurance, conduct routine safety surveillance in the department, and to meet regulatory demands in the workplace. All managers influence continuous quality improvement initiatives, from effective utilization of resource and staffing allocations, to efficacy of patient scheduling tactics. It is critically important to understand continuous quality improvement (CQI) and its relationship with the radiology manager, specifically quality assurance/quality control in routine work, as these are the fundamentals of institutional safety, including radiation safety. When an institution applies for a registration for radiation-producing devices or a license for the use of radioactive materials, the permit granting body has specific requirements, policies and procedures that must be satisfied in order to be granted a permit and to maintain it continuously. In the 32 U.S. Agreement states, which are states that have radiation safety programs equivalent to the Nuclear Regulatory Commission programs, individual facilities apply for permits through the local governing body of radiation protection. Other states are directly licensed by the Nuclear Regulatory Commission and associated regulatory entities. These regulatory agencies grant permits, set conditions for use in accordance with state and federal laws, monitor and enforce radiation safety activities, and audit facilities for compliance with their regulations. Every radiology department and associated areas of radiation use are subject to inspection and enforcement policies in order to ensure safety of equipment and personnel. In today's business practice, department managers or chief technologists may actively participate in the duties associated with institutional radiation safety, especially in smaller institutions, while

Investigating Astromaterials Curation Applications for Dexterous Robotic Arms

Snead, C. J.; Jang, J. H.; Cowden, T. R.; McCubbin, F. M.

2018-01-01

The Astromaterials Acquisition and Curation office at NASA Johnson Space Center is currently investigating tools and methods that will enable the curation of future astromaterials collections. Size and temperature constraints for astromaterials to be collected by current and future proposed missions will require the development of new robotic sample and tool handling capabilities. NASA Curation has investigated the application of robot arms in the past, and robotic 3-axis micromanipulators are currently in use for small particle curation in the Stardust and Cosmic Dust laboratories. While 3-axis micromanipulators have been extremely successful for activities involving the transfer of isolated particles in the 5-20 micron range (e.g. from microscope slide to epoxy bullet tip, beryllium SEM disk), their limited ranges of motion and lack of yaw, pitch, and roll degrees of freedom restrict their utility in other applications. For instance, curators removing particles from cosmic dust collectors by hand often employ scooping and rotating motions to successfully free trapped particles from the silicone oil coatings. Similar scooping and rotating motions are also employed when isolating a specific particle of interest from an aliquot of crushed meteorite. While cosmic dust curators have been remarkably successful with these kinds of particle manipulations using handheld tools, operator fatigue limits the number of particles that can be removed during a given extraction session. The challenges for curation of small particles will be exacerbated by mission requirements that samples be processed in N2 sample cabinets (i.e. gloveboxes). We have been investigating the use of compact robot arms to facilitate sample handling within gloveboxes. Six-axis robot arms potentially have applications beyond small particle manipulation. For instance, future sample return missions may involve biologically sensitive astromaterials that can be easily compromised by physical interaction with

Kulkarni, Prasad K; Shekhar, Susheela; Reddy, B N; Nirmala, B C

2011-09-01

Guidelines for measuring blood pressure includes measurement of blood pressure on both arms but it is often ignored. Our case report aims at highlighting the need follow the guidelines. A 60 year old 59 kg weighing male asymptomatic patient without any comobidities was posted for bilateral inguinal hernia repair. The interarm blood pressure difference was discovered incidentally during his preanaesthetic evalution. On further evaluation patient was found to be having subclavian stenosis on left side which was asymptomatic. Intraoperative and post operative period was uneventful. Blood pressure measurement should be done in accordance with the stipulated guidelines. Inter arm blood pressure difference should be noted in all patients as not only for diagnosis and treatment of hypertension but also as a tool to diagnose asymptomatic peripheral vascular disesase.

In clinical practice it is important to be able to assess the function of the upper limb of the patient who has suffered a stroke. There is currently no systemic review that could identify assessment tools for the 'fine use of the hand' and 'use of both hand and arm'. Primary, to identify observational tools which can assess the fine use of the hand and the use of both hand and arm in patients with stroke sequels. Secondary, to analyze the bias risk in the included articles, describing and categorizing the clinical utility, validity and reliability. A search was carried in Medline, LILACS, SciELO and Open Grey, which included articles published until October 2015. Studies that validate assessing tools of the upper limb in subjects with a stroke sequel which evaluate the fine use of the hand and the use of both hand and arm were included. Eleven tools in evaluate observational haven been selected, which assess the fine use of the hand and the use of hand and arm. In every case both validity and reliability have been reported, but clinical utility has been less considered for assessment. The studies that researched these tools showed a high risk of bias in their development. ARAT-19 showed a lower bias risk, but when it has to do with applicability and the reference trial is taken into account, the level of concern is high.

Overcoming the Range Limitation of Medium-Duty Battery Electric Vehicles through the use of Hydrogen Fuel-Cells

Energy Technology Data Exchange (ETDEWEB)

Wood, E.; Wang, L.; Gonder, J.; Ulsh, M.

2013-10-01

Battery electric vehicles possess great potential for decreasing lifecycle costs in medium-duty applications, a market segment currently dominated by internal combustion technology. Characterized by frequent repetition of similar routes and daily return to a central depot, medium-duty vocations are well positioned to leverage the low operating costs of battery electric vehicles. Unfortunately, the range limitation of commercially available battery electric vehicles acts as a barrier to widespread adoption. This paper describes the National Renewable Energy Laboratory's collaboration with the U.S. Department of Energy and industry partners to analyze the use of small hydrogen fuel-cell stacks to extend the range of battery electric vehicles as a means of improving utility, and presumably, increasing market adoption. This analysis employs real-world vocational data and near-term economic assumptions to (1) identify optimal component configurations for minimizing lifecycle costs, (2) benchmark economic performance relative to both battery electric and conventional powertrains, and (3) understand how the optimal design and its competitiveness change with respect to duty cycle and economic climate. It is found that small fuel-cell power units provide extended range at significantly lower capital and lifecycle costs than additional battery capacity alone. And while fuel-cell range-extended vehicles are not deemed economically competitive with conventional vehicles given present-day economic conditions, this paper identifies potential future scenarios where cost equivalency is achieved.

Laschi, C; Mazzolai, B; Mattoli, V; Cianchetti, M; Dario, P

2009-03-01

This paper reports the rationale and design of a robotic arm, as inspired by an octopus arm. The octopus arm shows peculiar features, such as the ability to bend in all directions, to produce fast elongations, and to vary its stiffness. The octopus achieves these unique motor skills, thanks to its peculiar muscular structure, named muscular hydrostat. Different muscles arranged on orthogonal planes generate an antagonistic action on each other in the muscular hydrostat, which does not change its volume during muscle contractions, and allow bending and elongation of the arm and stiffness variation. By drawing inspiration from natural skills of octopus, and by analysing the geometry and mechanics of the muscular structure of its arm, we propose the design of a robot arm consisting of an artificial muscular hydrostat structure, which is completely soft and compliant, but also able to stiffen. In this paper, we discuss the design criteria of the robotic arm and how this design and the special arrangement of its muscular structure may bring the building of a robotic arm into being, by showing the results obtained by mathematical models and prototypical mock-ups.

How does a planet excite multiple spiral arms?

Science.gov (United States)

Bae, Jaehan; Zhu, Zhaohuan

2018-01-01

Protoplanetary disk simulations show that a single planet excites multiple spiral arms in the background disk, potentially supported by the multi-armed spirals revealed with recent high-resolution observations in some disks. The existence of multiple spiral arms is of importance in many aspects. It is empirically found that the arm-to-arm separation increases as a function of the planetary mass, so one can use the morphology of observed spiral arms to infer the mass of unseen planets. In addition, a spiral arm opens a radial gap as it steepens into a shock, so when a planet excites multiple spiral arms it can open multiple gaps in the disk. Despite the important implications, however, the formation mechanism of multiple spiral arms has not been fully understood by far.In this talk, we explain how a planet excites multiple spiral arms. The gravitational potential of a planet can be decomposed into a Fourier series, a sum of individual azimuthal modes having different azimuthal wavenumbers. Using a linear wave theory, we first demonstrate that appropriate sets of Fourier decomposed waves can be in phase, raising a possibility that constructive interference among the waves can produce coherent structures - spiral arms. More than one spiral arm can form since such constructive interference can occur at different positions in the disk for different sets of waves. We then verify this hypothesis using a suite of two-dimensional hydrodynamic simulations. Finally, we present non-linear behavior in the formation of multiple spiral arms.

Barnes, V.; Fleming, I.; Grant, T.

1988-09-01

This report presents information gathered and analyzed in support of the United States Nuclear Regulatory Commission's (NRC's) efforts to develop a rule that will ensure that workers with unescorted access to protected areas in nuclear power plants are fit for duty. The primary potential fitness-for-duty concern addressed in the report is impairment caused by substance abuse, although other sources of impairment on the job are discussed. The report examines the prevalence of fitness-for-duty problems and discusses the use and effects of illicit drugs, prescription drugs, over-the-counter preparations and alcohol. The ways in which fitness-for-duty concerns are being addressed in both public- and private-sector industries are reviewed, and a description is provided of fitness-for-duty practices in six organizations that, like the nuclear industry, are regulated and whose operations can affect public health and safety. Methods of ensuring fitness for duty in the nuclear industry are examined in detail. The report also addresses methods of evaluating the effectiveness of fitness-for-duty programs in the nuclear power industry

Duty to disclose in medical genetics: a legal perspective.

Science.gov (United States)

Pelias, M Z

1991-06-01

As technical knowledge and public information in medical genetics continue to expand, the geneticist may expect to be held responsible for informing patients and clients about new developments in research and diagnosis. The long legal evolution of the physician's duty to disclose, and more recent findings of a physician's duty to recall former patients to inform them about newly discovered risks of treatment, indicate that medical geneticists may have a duty to disclose both current and future information about conditions that are or could be inherited. Recent case law supports findings of professional liability for both present and future disclosure, even in the absence of an active physician-patient relationship. The requirement of candid and complete disclosure will affect the counseling approach in testing for deleterious genes and in providing medical treatment for minors with hereditary diseases. Finding a duty to recall may impose further professional burdens on the geneticist to reach beyond the immediate counseling arena and to recontact patients, perhaps years after their initial visit to genetics clinic.

A Comparison of Image Quality and Radiation Exposure Between the Mini C-Arm and the Standard C-Arm.

van Rappard, Juliaan R M; Hummel, Willy A; de Jong, Tijmen; Mouës, Chantal M

2018-04-01

The use of intraoperative fluoroscopy has become mandatory in osseous hand surgery. Due to its overall practicality, the mini C-arm has gained popularity among hand surgeons over the standard C-arm. This study compares image quality and radiation exposure for patient and staff between the mini C-arm and the standard C-arm, both with flat panel technology. An observer-based subjective image quality study was performed using a contrast detail (CD) phantom. Five independent observers were asked to determine the smallest circles discernable to them. The results were plotted in a graph, forming a CD curve. From each curve, an image quality figure (IQF) was derived. A lower IQF equates to a better image quality. The patients' entrance skin dose was measured, and to obtain more information about the staff exposure dose, a perspex hand phantom was used. The scatter radiation was measured at various distances and angles relative to a central point on the detector. The IQF was significantly lower for the mini C-arm resulting in a better image quality. The patients' entrance dose was 10 times higher for the mini C-arm as compared with the standard C-arm, and the scatter radiation threefold. Due to its improved image quality and overall practicality, the mini C-arm is recommended for hand surgical procedures. To ensure that the surgeons' radiation exposure is not exceeding the safety limits, monitoring radiation exposure using mini C-arms with flat panel technology during surgery should be done in a future clinical study.

Changes in arm-hand function and arm-hand skill performance in patients after stroke during and after rehabilitation.

Franck, Johan Anton; Smeets, Rob Johannes Elise Marie; Seelen, Henk Alexander Maria

2017-01-01

Arm-hand rehabilitation programs applied in stroke rehabilitation frequently target specific populations and thus are less applicable in heterogeneous patient populations. Besides, changes in arm-hand function (AHF) and arm-hand skill performance (AHSP) during and after a specific and well-described rehabilitation treatment are often not well evaluated. This single-armed prospective cohort study featured three subgroups of stroke patients with either a severely, moderately or mildly impaired AHF. Rehabilitation treatment consisted of a Concise_Arm_and_hand_ Rehabilitation_Approach_in_Stroke (CARAS). Measurements at function and activity level were performed at admission, clinical discharge, 3, 6, 9 and 12 months after clinical discharge. Eighty-nine stroke patients (M/F:63/23; mean age:57.6yr (+/-10.6); post-stroke time:29.8 days (+/-20.1)) participated. All patients improved on AHF and arm-hand capacity during and after rehabilitation, except on grip strength in the severely affected subgroup. Largest gains occurred in patients with a moderately affected AHF. As to self-perceived AHSP, on average, all subgroups improved over time. A small percentage of patients declined regarding self-perceived AHSP post-rehabilitation. A majority of stroke patients across the whole arm-hand impairment severity spectrum significantly improved on AHF, arm-hand capacity and self-perceived AHSP. These were maintained up to one year post-rehabilitation. Results may serve as a control condition in future studies.

NONE

1997-04-01

This model curriculum outline was developed using a turbo-DACUM (Developing a Curriculum) process which utilizes practicing experts to undertake a comprehensive job and task analysis. The job and task analysis serves to establish current baseline data accurately and to improve both the process and the product of the job through constant and continuous improvement of training. The DACUM process is based on the following assumptions: (1) Expert workers are the best source for task analysis. (2) Any occupation can be described effectively in terms of tasks. (3) All tasks imply knowledge, skills, and attitudes/values. A DACUM panel, comprised of six experienced and knowledgeable technicians who are presently working in the field, was given an orientation to the DACUM process. The panel then identified, verified, and sequenced all the necessary job duty areas and tasks. The broad duty categories were rated according to relative importance and assigned percentage ratings in priority order. The panel then rated every task for each of the duties on a scale of 1 to 3. A rating of 3 indicates an {open_quotes}essential{close_quotes} task, a rating of 2 indicates an {open_quotes}important{close_quotes} task, and a rating of 1 indicates a {open_quotes}desirable{close_quotes} task.

Duty of care is underpinned by a range of obligations.

Science.gov (United States)

Griffith, Richard

The courts have long established that nurses are in a duty situation and owe a duty of care to their patients (Kent v Griffiths [2001]). Traditionally, the profession set the standard of care and nurses were required to act in accordance with a practice accepted by a responsible body of their peers (Bolam v Friern HMC [1957]).The introduction of the Human Rights Act 1998 gave rise to a positive obligation on government to ensure that laws, policies and procedures are in place to protect violations of human rights. Nurses must now inform their practice with relevant statute law, common law and professional standards in order to properly discharge their duty of care. Richard Griffith considers the law that now underpins a nurse's duty of care and uses a recent report from the Health Service Ombudsman for England to illustrate the obligations that underpin the nurse-patient relationship.

Coordination of dual robot arms using kinematic redundancy

Science.gov (United States)

Suh, Il Hong; Shin, Kang G.

1988-01-01

A method is developed to coordinate the motion of dual robot arms carrying a solid object, where the first robot (leader) grasps one end of the object rigidly and the second robot (follower) is allowed to change its grasping position at the other end of the object along the object surface while supporting the object. It is shown that this flexible grasping is equivalent to the addition of one more degree of freedom (dof), giving the follower more maneuvering capabilities. In particular, motion commands for the follower are generated by using kinematic redundancy. To show the utility and power of the method, an example system with two PUMA 560 robots carrying a beam is analyzed.

On-call duty effects on sleep-state physiological stability in male medical interns.

Directory of Open Access Journals (Sweden)

Yu-Hsuan Lin

Full Text Available BACKGROUND: On-call duty among medical interns is characterized by sleep deprivation and stressful working conditions, both of which alter cardiac autonomic modulation. We hypothesized that sleep stability decreased in medical interns during on-call duty. We used cardiopulmonary-coupling (CPC analysis to test our hypothesis. METHODS: We used electrocardiogram (ECG-based CPC analysis to quantify physiological parameters of sleep stability in 13 medical interns during on-call and on-call duty-free periods. There were ten 33.5-h on-call duty shifts per month for interns, each followed by 2 on-call duty-free days, over 3 months. Measurements during sleep were collected before, during, and after an on-call shift. Measurements were repeated 3 months later during an on-call duty-free period. RESULTS: The medical interns had significantly reduced stable sleep, and displayed increased latency to the first epoch of stable sleep during the on-call night shift, compared to the pre-call and on-call duty-free nights. Interns also had significantly increased rapid-eye-movement (REM sleep during the on-call night shift, compared to the pre-call and on-call duty-free nights. CONCLUSION: Medical interns suffer disrupted sleep stability and continuity during on-call night shifts. The ECG-based CPC analysis provides a straightforward means to quantify sleep quality and stability in medical staff performing shift work under stressful conditions.

The duty health physicist program at Byron Nuclear Power Station

International Nuclear Information System (INIS)

Goldsmith, D.G.; Carey, T.R.

1987-01-01

The Duty Health Physicist Program at Byron Station was established to deal with routine health physics tasks and provide an interface between frontline and upper radiation-chemistry management. The program consists of a weekly rotation of selected members of the health physics staff into the duty health physicist position to handle the assigned duty tasks. The tasks include, but are not limited to, daily isotopic and air sample review, effluent release package review, maximum permissible concentration calculations, dose approvals, as-low-as-reasonably-achievable action review of pending jobs, and general availability to answer questions and address problems in health-physics-related areas of plant operation. The daily attendance of the duty health physicist at the radiation-chemistry and station plan-of-the-day meetings has increased the overall presence and visibility of the health physics program to upper station management and other station departments. Since its inception in July of 1985, the Duty Health Physics Program has been a major contributor to the observed 50% reduction in reportable personnel errors in the radiation-chemistry department (based on personnel-error-related deviation reports and license event reports generated on the radiation-chemistry department at Byron Station). Although difficulty to quantify, other important benefits of this program are also discussed in this paper

Kant on euthanasia and the duty to die: clearing the air.

Science.gov (United States)

Cholbi, Michael

2015-08-01

Thanks to recent scholarship, Kant is no longer seen as the dogmatic opponent of suicide that he appears to be at first glance. However, some interpreters have recently argued for a Kantian view of the morality of suicide with surprising, even radical, implications. More specifically, they have argued that Kantianism (1) requires that those with dementia or other rationality-eroding conditions end their lives before their condition results in their loss of identity as moral agents and (2) requires subjecting the fully demented or those confronting future dementia to non-voluntary euthanasia. Properly understood, Kant's ethics have neither of these implications (1) wrongly assumes that rational agents' duty of self-preservation entails a duty of self-destruction when they become non-rational, (2) further neglects Kant's distinction between duties to self and duties to others and wrongly assumes that duties can be owed to rational agents only during the time of their existence.

CHARACTERISTICS OF SPIRAL ARMS IN LATE-TYPE GALAXIES

International Nuclear Information System (INIS)

Honig, Z. N.; Reid, M. J.

2015-01-01

We have measured the positions of large numbers of H II regions in four nearly face-on, late-type, spiral galaxies: NGC 628 (M74), NGC 1232, NGC 3184, and NGC 5194 (M51). Fitting log-periodic spiral models to segments of each arm yields local estimates of spiral pitch angle and arm width. While pitch angles vary considerably along individual arms, among arms within a galaxy, and among galaxies, we find no systematic trend with galactocentric distance. We estimate the widths of the arm segments from the scatter in the distances of the H II regions from the spiral model. All major arms in these galaxies show spiral arm width increasing with distance from the galactic center, similar to the trend seen in the Milky Way. However, in the outermost parts of the galaxies, where massive star formation declines, some arms reverse this trend and narrow. We find that spiral arms often appear to be composed of segments of ∼5 kpc length, which join to form kinks and abrupt changes in pitch angle and arm width; these characteristics are consistent with properties seen in the large N-body simulations of D'Onghia et al. and others

Organizational interventions in response to duty hour reforms.

Law, Madelyn P; Orlando, Elaina; Baker, G Ross

2014-01-01

Changes in resident duty hours in Europe and North America have had a major impact on the internal organizational dynamics of health care organizations. This paper examines, and assesses the impact of, organizational interventions that were a direct response to these duty hour reforms. The academic literature was searched through the SCOPUS database using the search terms "resident duty hours" and "European Working Time Directive," together with terms related to organizational factors. The search was limited to English-language literature published between January 2003 and January 2012. Studies were included if they reported an organizational intervention and measured an organizational outcome. Twenty-five articles were included from the United States (n=18), the United Kingdom (n=5), Hong Kong (n=1), and Australia (n=1). They all described single-site projects; the majority used post-intervention surveys (n=15) and audit techniques (n=4). The studies assessed organizational measures, including relationships among staff, work satisfaction, continuity of care, workflow, compliance, workload, and cost. Interventions included using new technologies to improve handovers and communications, changing staff mixes, and introducing new shift structures, all of which had varying effects on the organizational measures listed previously. Little research has assessed the organizational impact of duty hour reforms; however, the literature reviewed demonstrates that many organizations are using new technologies, new personnel, and revised and innovative shift structures to compensate for reduced resident coverage and to decrease the risk of limited continuity of care. Future research in this area should focus on both micro (e.g., use of technology, shift changes, staff mix) and macro (e.g., culture, leadership support) organizational aspects to aid in our understanding of how best to respond to these duty hour reforms.

Transparency, Trust and Security: An Evaluation of the Insurer's Precontractual Duties

Full Text Available Transparency in insurance law attaches to the rights and duties of the parties, the relationships between insurers, insurance intermediaries such as agents and brokers, insurance supervisory law and insurance dispute resolution procedures. Regarding the rights and duties of the insurer and the prospective policyholder, it requires insurers to disclose precontractual information in a timely manner that is clear, understandable, legible and unambiguous. Transparency as a value is incredibly important in insurance contracts. This contribution focuses exclusively on the insurer's duty of disclosure during precontractual negotiations. Although the insured's duty of disclosure has enjoyed more attention in the past, the duty clearly applies to the insurance proposer as well as the insurer. The purpose of this contribution is to evaluate the nature and extent of the insurer's transparency duties as informed by both common and statutory laws. The insurer's duty is derived primarily from the statutory rights of access to information in accordance with the provisions of the Constitution of the Republic of South Africa and the Promotion of Access to Information Act. It is furthermore supported by specific insurance consumer protection law found in the detailed provisions on mandatory disclosures in the Financial Advisory and Intermediary Services Act, the Long-term Insurance Act, the Short-term Insurance Act and, finally, the Policyholder Protection Rules issued in accordance with these acts. Strict rules on advertising can be found in the General Code of Conduct issued under the FAIS Act. The Act furthermore specifically targets the activities of insurance intermediaries in precontractual disclosures. The fact that insurance products and services have been exempted from the scope of the Consumer Protection Act from 28 February 2014 should not diminish the insured's right to rely on universal consumer protection principles as envisaged by South African

Robot-assisted rehabilitation of stroke survivors mainly focuses on the impaired side of the body while the role of the unimpaired side in the recovery after stroke is still controversial. The goal of this study is to investigate the influence on sitting balance and paretic arm functions of a training protocol based on movements of the unimpaired arm. Sixteen chronic stroke survivors underwent nineteen training sessions, in which they performed active movements with the unimpaired arm supported by a passive exoskeleton. Performance of the trunk and upper limbs was evaluated before treatment, after treatment and at six months follow up with clinical scales and an instrumented evaluation. A reaching test executed with the exoskeleton was used to assess changes in performance of both arms. The treatment based on the unimpaired arm's movements executed with a correct body posture led to benefits in control of the trunk and of both the trained and the untrained arm. The amount of impaired arm improvement in the Fugl-Meyer score was comparable to the outcome of robotic treatments focused directly on this arm. Our results highlight the importance of taking into account all body schema in the rehabilitation robotic program, instead of focusing only on the impaired side of the body.

Family victim advocates: the importance of critical job duties

Directory of Open Access Journals (Sweden)

Teresa H. Young

Full Text Available Child advocacy centers across the United States intervened in more than 250,000 child abuse cases in 2011(National Children's Alliance, 2012. Understanding the work of family victim advocates is imperative to helping children and families in child abuse cases. In this exploratory study, we surveyed advocates and program directors from child advocacy centers (CACs across the United States to compare their perceptions of the critical job duties of family victim advocates. Data analysis revealed that CAC directors rated the importance of these duties significantly higher than family victim advocates. Results suggest the need for additional training to ensure that family victim advocates understand the importance of critical job duties to meet the needs of children and families in child abuse cases.

This report describes work performed for an Early Career Research and Development project. This project developed a heavy-duty vehicle (HDV) sector model to assess the factors influencing alternative fuel and efficiency technology adoption. This model builds on a Sandia light duty vehicle sector model and provides a platform for assessing potential impacts of technological advancements developed at the Combustion Research Facility. Alternative fuel and technology adoption modeling is typically developed around a small set of scenarios. This HDV sector model segments the HDV sector and parameterizes input values, such as fuel prices, efficiencies, and vehicle costs. This parameterization enables sensitivity and trade space analyses to identify the inputs that are most associated with outputs of interest, such as diesel consumption and greenhouse gas emissions. Thus this analysis tool enables identification of the most significant HDV sector drivers that can be used to support energy security and climate change goals.

A logarithmic spiral is a prominent feature appearing in a majority of observed galaxies. This feature has long been associated with the traditional Hubble classification scheme, but historical quotes of pitch angle of spiral galaxies have been almost exclusively qualitative. We have developed a methodology, utilizing two-dimensional fast Fourier transformations of images of spiral galaxies, in order to isolate and measure the pitch angles of their spiral arms. Our technique provides a quantitative way to measure this morphological feature. This will allow comparison of spiral galaxy pitch angle to other galactic parameters and test spiral arm genesis theories. In this work, we detail our image processing and analysis of spiral galaxy images and discuss the robustness of our analysis techniques.

Zhang Zhiyong

2014-01-01

Full Text Available The picking robot arm is scheduled to complete picking tasks in the working space, to overcome the shaking vibration to improve the picking stability, its movement should follow specific consistence trajectory points. Usually we should give definite multiple feature picking points, map their inverse kinematics to the joint space, establish motion equation for the corresponding point in the joint space, then follow these equations motion for the interpolation on the joint so that we can meet the movement requirements. Trajectory planning is decisive significance for accuracy and stability of controlling robot arm. The key issue that picking arm complete picking task will be come true by trajectory planning, namely, robot arm track the desired trajectory. which based on kinematics and statics picking analysis in a joint space according to the requirements of picking tasks, and obtain the position and orientation for picking robot arm, study and calculate the theory of trajectory parameters timely.

Arm locking with Doppler estimation errors

Yu Yinan; Wand, Vinzenz; Mitryk, Shawn; Mueller, Guido, E-mail: yinan@phys.ufl.ed [Department of Physics, University of Florida, Gainesville, FL 32611 (United States)

2010-05-01

At the University of Florida we developed the University of Florida LISA Interferometer Simulator (UFLIS) in order to study LISA interferometry with hardware in the loop at a system level. One of the proposed laser frequency stabilization techniques in LISA is arm locking. Arm locking uses an adequately filtered linear combination of the LISA arm signals as a frequency reference. We will report about experiments in which we demonstrated arm locking using UFLIS. During these experiments we also discovered a problem associated with the Doppler shift of the return beam. The initial arm locking publications assumed that this Doppler shift can perfectly be subtracted inside the phasemeter or adds an insignificant offset to the sensor signal. However, the remaining Doppler knowledge error will cause a constant change in the laser frequency if unaccounted for. Several ways to circumvent this problem have been identified. We performed detailed simulations and started preliminary experiments to verify the performance of the proposed new controller designs.

Supporting the President's Arms Control and Nonproliferation Agenda: Transparency and Verification for Nuclear Arms Reductions

International Nuclear Information System (INIS)

Doyle, James E.; Meek, Elizabeth

2009-01-01

The President's arms control and nonproliferation agenda is still evolving and the details of initiatives supporting it remain undefined. This means that DOE, NNSA, NA-20, NA-24 and the national laboratories can help define the agenda, and the policies and the initiatives to support it. This will require effective internal and interagency coordination. The arms control and nonproliferation agenda is broad and includes the path-breaking goal of creating conditions for the elimination of nuclear weapons. Responsibility for various elements of the agenda will be widely scattered across the interagency. Therefore an interagency mapping exercise should be performed to identify the key points of engagement within NNSA and other agencies for creating effective policy coordination mechanisms. These can include informal networks, working groups, coordinating committees, interagency task forces, etc. It will be important for NA-20 and NA-24 to get a seat at the table and a functional role in many of these coordinating bodies. The arms control and nonproliferation agenda comprises both mature and developing policy initiatives. The more mature elements such as CTBT ratification and a follow-on strategic nuclear arms treaty with Russia have defined milestones. However, recent press reports indicate that even the START follow-on strategic arms pact that is planned to be complete by the end of 2009 may take significantly longer and be more expansive in scope. The Russians called for proposals to count non-deployed as well as deployed warheads. Other elements of the agenda such as FMCT, future bilateral nuclear arms reductions following a START follow-on treaty, nuclear posture changes, preparations for an international nuclear security summit, strengthened international safeguards and multilateral verification are in much earlier stages of development. For this reason any survey of arms control capabilities within the USG should be structured to address potential needs across the

Surgical Simulations Based on Limited Quantitative Data: Understanding How Musculoskeletal Models Can Be Used to Predict Moment Arms and Guide Experimental Design.

Directory of Open Access Journals (Sweden)

Jennifer A Nichols

Full Text Available The utility of biomechanical models and simulations to examine clinical problems is currently limited by the need for extensive amounts of experimental data describing how a given procedure or disease affects the musculoskeletal system. Methods capable of predicting how individual biomechanical parameters are altered by surgery are necessary for the efficient development of surgical simulations. In this study, we evaluate to what extent models based on limited amounts of quantitative data can be used to predict how surgery influences muscle moment arms, a critical parameter that defines how muscle force is transformed into joint torque. We specifically examine proximal row carpectomy and scaphoid-excision four-corner fusion, two common surgeries to treat wrist osteoarthritis. Using models of these surgeries, which are based on limited data and many assumptions, we perform simulations to formulate a hypothesis regarding how these wrist surgeries influence muscle moment arms. Importantly, the hypothesis is based on analysis of only the primary wrist muscles. We then test the simulation-based hypothesis using a cadaveric experiment that measures moment arms of both the primary wrist and extrinsic thumb muscles. The measured moment arms of the primary wrist muscles are used to verify the hypothesis, while those of the extrinsic thumb muscles are used as cross-validation to test whether the hypothesis is generalizable. The moment arms estimated by the models and measured in the cadaveric experiment both indicate that a critical difference between the surgeries is how they alter radial-ulnar deviation versus flexion-extension moment arms at the wrist. Thus, our results demonstrate that models based on limited quantitative data can provide novel insights. This work also highlights that synergistically utilizing simulation and experimental methods can aid the design of experiments and make it possible to test the predictive limits of current computer

Simulation of Octopus Arm Based on Coupled CPGs

Directory of Open Access Journals (Sweden)

Juan Tian

2015-01-01

Full Text Available The octopus arm has attracted many researchers’ interests and became a research hot spot because of its amazing features. Several dynamic models inspired by an octopus arm are presented to realize the structure with a large number of degrees of freedom. The octopus arm is made of a soft material introducing high-dimensionality, nonlinearity, and elasticity, which makes the octopus arm difficult to control. In this paper, three coupled central pattern generators (CPGs are built and a 2-dimensional dynamic model of the octopus arm is presented to explore possible strategies of the octopus movement control. And the CPGs’ signals treated as activation are added on the ventral, dorsal, and transversal sides, respectively. The effects of the octopus arm are discussed when the parameters of the CPGs are changed. Simulations show that the octopus arm movements are mainly determined by the shapes of three CPGs’ phase diagrams. Therefore, some locomotion modes are supposed to be embedded in the neuromuscular system of the octopus arm. And the octopus arm movements can be achieved by modulating the parameters of the CPGs. The results are beneficial for researchers to understand the octopus movement further.

A numerical investigation of flow around octopus-like arms: near-wake vortex patterns and force development.

Science.gov (United States)

Kazakidi, A; Vavourakis, V; Tsakiris, D P; Ekaterinaris, J A

2015-01-01

The fluid dynamics of cephalopods has so far received little attention in the literature, due to their complexity in structure and locomotion. The flow around octopuses, in particular, can be complicated due to their agile and dexterous arms, which frequently display some of the most diverse mechanisms of motion. The study of this flow amounts to a specific instance of the hydrodynamics problem for rough tapered cylinder geometries. The outstanding manipulative and locomotor skills of octopuses could inspire the development of advanced robotic arms, able to operate in fluid environments. Our primary aim was to study the hydrodynamic characteristics of such bio-inspired robotic models and to derive the hydrodynamic force coefficients as a concise description of the vortical flow effects. Utilizing computational fluid dynamic methods, the coefficients were computed on realistic morphologies of octopus-like arm models undergoing prescribed solid-body movements; such motions occur in nature for short durations in time, e.g. during reaching movements and exploratory behaviors. Numerical simulations were performed on translating, impulsively rotating, and maneuvering arms, around which the flow field structures were investigated. The results reveal in detail the generation of complex vortical flow structures around the moving arms. Hydrodynamic forces acting on a translating arm depend on the angle of incidence; forces generated during impulsive rotations of the arms are independent of their exact morphology and the angle of rotation; periodic motions based on a slow recovery and a fast power stroke are able to produce considerable propulsive thrust while harmonic motions are not. Parts of these results have been employed in bio-inspired models of underwater robotic mechanisms. This investigation may further assist elucidating the hydrodynamics underlying aspects of octopus locomotion and exploratory behaviors.

International security and arms control

International Nuclear Information System (INIS)

Ekeus, R.

2000-01-01

The end of the cold war also ended the focus on the bilateral approach to arms control and disarmament. Key concepts of security needed to be revisited, along with their implications for the disarmament and arms control agenda. Though there is currently a unipolar global security environment, there remain important tasks on the multilateral arms control agenda. The major task is that of reducing and eliminating weapons of mass destruction, especially nuclear weapons. The author contends that maintaining reliance on the nuclear-weapons option makes little sense in a time when the major Powers are strengthening their partnerships in economics, trade, peacemaking and building.

This report summarizes the data from the semiannual reports on fitness-for-duty programs submitted to the NRC by 54 utilities for two reporting periods: January 3, 1990, to June 30, 1990, and from July 1, 1990, to December 31, 1990. During CY 1990, licensees reported that they conducted 278,209 tests for the presence of illegal drugs and alcohol. Of these tests, 2409 (.87%) were positive. Positive test results varied by category of test and category of worker. The majority of positive test results (1548) were obtained through pre-access testing. Of tests conducted on workers having access to the protected area, there were 550 positive tests from random testing, and 214 positive tests form for-cause testing. Followup testing of workers who had previously tested positive resulted in 65 positive tests. Positive test results also varied by category of worker. Overall, short-term and long-term contractor personnel had the highest rates of positive tests. Licensee employees had lower rates of positive test results. 22 figs., 7 tabs

Real-world exhaust temperature profiles of on-road heavy-duty diesel vehicles equipped with selective catalytic reduction.

On-road heavy-duty diesel vehicles are a major contributor of oxides of nitrogen (NO x ) emissions. In the US, many heavy-duty diesel vehicles employ selective catalytic reduction (SCR) technology to meet the 2010 emission standard for NO x . Typically, SCR needs to be at least 200°C before a significant level of NO x reduction is achieved. However, this SCR temperature requirement may not be met under some real-world operating conditions, such as during cold starts, long idling, or low speed/low engine load driving activities. The frequency of vehicle operation with low SCR temperature varies partly by the vehicle's vocational use. In this study, detailed vehicle and engine activity data were collected from 90 heavy-duty vehicles involved in a range of vocations, including line haul, drayage, construction, agricultural, food distribution, beverage distribution, refuse, public work, and utility repair. The data were used to create real-world SCR temperature and engine load profiles and identify the fraction of vehicle operating time that SCR may not be as effective for NO x control. It is found that the vehicles participated in this study operate with SCR temperature lower than 200°C for 11-70% of the time depending on their vocation type. This implies that real-world NO x control efficiency could deviate from the control efficiency observed during engine certification. Copyright © 2018 Elsevier B.V. All rights reserved.

Strategic arms limitation

Science.gov (United States)

Allen Greb, G.; Johnson, Gerald W.

1983-10-01

Following World War II, American scientists and politicians proposed in the Baruch plan a radical solution to the problem of nuclear weapons: to eliminate them forever under the auspices of an international nuclear development authority. The Soviets, who as yet did not possess the bomb, rejected this plan. Another approach suggested by Secretary of War Henry Stimson to negotiate directly with the Soviet Union was not accepted by the American leadership. These initial arms limitation failures both reflected and exacerbated the hostile political relationship of the superpowers in the 1950s and 1960s. Since 1969, the more modest focus of the Soviet-American arms control process has been on limiting the numbers and sizes of both defensive and offensive strategic systems. The format for this effort has been the Strategic Arms Limitatins Talks (Salt) and more recently the Strategic Arms Reduction Talks (START). Both sides came to these negotiations convinced that nuclear arsenals had grown so large that some for of mutual restraint was needed. Although the SALT/START process has been slow and ponderous, it has produced several concrete the agreements and collateral benefits. The 1972 ABM Treaty restricts the deployment of ballistic missile defense systems, the 1972 Interim Agreement places a quantitative freeze on each side's land based and sea based strategic launchers, and the as yet unratified 1979 SALT II Treaty sets numerical limits on all offensive strategic systems and sublimits on MIRVed systems. Collateral benefits include improved verification procedures, working definitions and counting rules, and permanent bureaucratic apparatus which enhance stability and increase the chances for achieving additional agreements.

Commentary: so the pendulum swings--making sense of the duty to protect.

Science.gov (United States)

Fox, Patrick K

2010-01-01

Psychiatry has been struggling for nearly 40 years to make sense of the duty to protect. The great jurisdictional disparity as to what constitutes the duty has been a significant contributing factor. The American Psychiatric Association (APA) released the Model Statute in 1987 to establish a framework to guide legislators and courts toward consensus, to some effect. In response to case law and statutory requirements in most states, psychiatric practice has incorporated the assessment of risk to third parties by patients as an essential element of psychiatric assessment and care. Although court cases shortly after the Tarasoff decision expanded the scope and breadth of the duty to protect, in recent years there appears to have been a shift toward a more narrow interpretation as to what conditions must exist to find a defendant psychiatrist guilty of failing to exercise the duty properly. The threshold for the duty to warn or protect often rests precariously beside the criteria permitting an exception to confidentiality, placing the psychiatrist in a tenuous position. If appellate verdicts continue to find for the defendant psychiatrist in cases claiming a breach of the duty to protect, it could have an impact on how psychiatrists assess and manage threats made by patients toward third parties.

Planet-driven Spiral Arms in Protoplanetary Disks. II. Implications

Science.gov (United States)

Bae, Jaehan; Zhu, Zhaohuan

2018-06-01

We examine whether various characteristics of planet-driven spiral arms can be used to constrain the masses of unseen planets and their positions within their disks. By carrying out two-dimensional hydrodynamic simulations varying planet mass and disk gas temperature, we find that a larger number of spiral arms form with a smaller planet mass and a lower disk temperature. A planet excites two or more spiral arms interior to its orbit for a range of disk temperatures characterized by the disk aspect ratio 0.04≤slant {(h/r)}p≤slant 0.15, whereas exterior to a planet’s orbit multiple spiral arms can form only in cold disks with {(h/r)}p≲ 0.06. Constraining the planet mass with the pitch angle of spiral arms requires accurate disk temperature measurements that might be challenging even with ALMA. However, the property that the pitch angle of planet-driven spiral arms decreases away from the planet can be a powerful diagnostic to determine whether the planet is located interior or exterior to the observed spirals. The arm-to-arm separations increase as a function of planet mass, consistent with previous studies; however, the exact slope depends on disk temperature as well as the radial location where the arm-to-arm separations are measured. We apply these diagnostics to the spiral arms seen in MWC 758 and Elias 2–27. As shown in Bae et al., planet-driven spiral arms can create concentric rings and gaps, which can produce a more dominant observable signature than spiral arms under certain circumstances. We discuss the observability of planet-driven spiral arms versus rings and gaps.

Study on the method or reducing the operator's exposure dose from a C-Arm system

In this study, C-Arm equipment is being used as we intend to verify the exposure dose on the operator by the scattering rays during the operation of the C-Arm equipment and to provide an effective method of reducing the exposure dose. Exposure dose is less than the Over Tube method utilizes the C-arm equipment Under Tube the scheme, The result showed that the exposure dose on the operator decreased with a thicker shield, and as the operator moved away from the center line. Moreover, as the research time prolongated, the exposure dose increased, and among the three affixed location of the dosimeter, the most exposure dose was measured at gonadal, then followed by chest and thyroid. However, in consideration of the relationship between the operator and the patient, the distance cannot be increased infinitely and the research time cannot be decreased infinitely in order to reduce the exposure dose. Therefore, by changing the thickness of the radiation shield, the exposure dose on the operator was able to be reduced. If you are using a C-Arm equipment discomfort during surgery because the grounds that the procedure is neglected and close to the dose of radiation shielding made can only increase. Because a separate control room cannot be used for the C-Arm equipment due to its characteristic, the exposure dose on the operator needs to be reduced by reinforcing the shield through an appropriate thickness of radiation shield devices, such as apron, etc. during a treatment

2008-10-01

Emission from 7 typical light-duty vehicles under actual driving conditions was monitored using a portable emission measurement system to gather data for characterization of the real world vehicle emission in Shenzhen, including the effects of driving modes on vehicle emission, comparison of fuel consumption based emission factors (g x L(-1) with mileage based emission factors (g x km(-1)), and the average emission factors of the monitored vehicles. The acceleration and deceleration modes accounted for 66.7% of total travel time, 80.3% of traveling distance and 74.6%-79.2% of vehicle emission; the acceleration mode contributed more than other driving modes. The fuel based emission factors were less dependent on the driving speed; they may be utilized in building macro-scale vehicle emission inventory with smaller sensitivity to the vehicle driving conditions. The effect of vehicle technology on vehicle emission was significant; the emission factors of CO, HC and NO(x) of carbureted vehicles were 19.9-20.5, 5.6-26.1 and 1.8-2.0 times the more advanced vehicles of Euro II, respectively. Using the ECE + EUDC driving cycle would not produce the desired real-world emission rates of light duty vehicles in a typical Chinese city.

be made approximately a year before launch, but there is a strong recommendation from the scientific and resource utilization communities that the ARM target be volatile and organic rich. Three of the proposed candidates are carbonaceous NEAs. Specifically, the ARRM reference target, 2008 EV5 is a carbonaceous (C-type) asteroid that has been remotely characterized (via visual, infrared, and radar wavelengths), is believed to be hydrated, and provides significant return mass (boulders on the surface greater than 20 metric tons). It also has an advantage in that the orbital dynamics of the NEA fall within the current baseline mission timeline of five years between the return of the robotic vehicle to cis-lunar space and the launch of the ARCM. Therefore, NEA 2008 EV5 provides a valid target that can be used to help with formulation and development efforts. Input to ARM and Future Activities: In the fall of 2015, NASA chartered the Formulation Assessment and Support Team (FAST) to provide timely inputs for mission requirement formulation in support of the ARRM Requirements Closure Technical Interchange Meeting (TIM) in mid-December of 2015, to assist in developing an initial list of potential mission investigations, and to provide input on potential hosted payloads and partnerships. Expertise from the science, engineering, and technology communities was represented in exploring lines of inquiry related to key characteristics of the ARRM reference target asteroid (2008 EV5) for engineering design purposes. As of December 2015, the FAST has been formally retired and the FAST final report was publically released in February of 2016. However, plans have been made to stand up an ARM Investigation Team (IT), which is expected be formed in 2016. The multidisciplinary IT will assist with the definition and support of mission investigations, support ARM program-level and project-level functions, and support NASA Head-quarters interactions with the science and technology

Mechanical characterization of the Varian Exact-arm and R-arm support systems for eight aS500 electronic portal imaging devices

International Nuclear Information System (INIS)

Grattan, Mark W. D.; McGarry, Conor K.

2010-01-01

Purpose: The aim of this study is to compare the positioning accuracy at different gantry angles of two electronic portal imaging devices (EPIDs) support arm systems by using EPID difference images as a measure for displacement. This work presents a comparison of the mechanical performance of eight Varian aS500 (Varian Medical Systems, Palo Alto, CA) EPIDs, mounted using either the Varian Exact-arm or R-arm. Methods: The mechanical performance of the two arm systems was compared by investigating the variation in sensitivity with gantry angle, both before and after the EPID position was adjusted after gantry rotation. Positional errors were investigated by subtracting images from a reference image taken at gantry 0 deg., and the amplitude of the peaks and troughs at the field edges for longitudinal (radial) and lateral (transverse) profiles across the resulting image was related to the distance of displacement. Calibration curves based on a pixel-by-pixel shift were generated for each EPID and the Varian hand pendant accuracy was compared to the calibration data. Results: The response of the EPIDs was found to change with gantry rotation, with the largest difference at 180 deg. The Exact-arm was found to correct well for any displacement, while the R-arm tended to overcorrect following repositioning using the hand pendant. The calibration curves were consistent within each set of matched linacs, and the hand pendant accuracy was similar for both arm systems, although generally in different directions. With respect to gantry rotation effects, the mechanical performance of the Exact-arm systems was found to be much better than that of the R-arm systems. At gantry positions 90 deg., 270 deg., and 180 deg. the average misalignment in the longitudinal direction was +4.2±0.2, +1.8±1.6, and +7.4±0.5 mm for the R-arms, and +2.9±0.2, +2.1±0.8, and +4.9±0.7 mm for the Exact-arms. In the lateral direction the average positional errors were +2.1±0.4, -4.7±0.4, and -2.5�

DePasquale, Nicole; Zarit, Steven H; Mogle, Jacqueline; Moen, Phyllis; Hammer, Leslie B; Almeida, David M

2018-04-01

Based on the stress process model of family caregiving, this study examined subjective stress appraisals and perceived schedule control among men employed in the long-term care industry (workplace-only caregivers) who concurrently occupied unpaid family caregiving roles for children (double-duty child caregivers), older adults (double-duty elder caregivers), and both children and older adults (triple-duty caregivers). Survey responses from 123 men working in nursing home facilities in the United States were analyzed using multiple linear regression models. Results indicated that workplace-only and double- and triple-duty caregivers' appraised primary stress similarly. However, several differences emerged with respect to secondary role strains, specifically work-family conflict, emotional exhaustion, and turnover intentions. Schedule control also constituted a stress buffer for double- and triple-duty caregivers, particularly among double-duty elder caregivers. These findings contribute to the scarce literature on double- and triple-duty caregiving men and have practical implications for recruitment and retention strategies in the health care industry.

Rolling motions in an inner spiral arm

International Nuclear Information System (INIS)

Strauss, F.M.; Poeppel, W.

1976-01-01

Hydrogen line observations made at low galactic latitudes for l=318degree, 326degree, 334degree, and 337degree show the presence of velocity gradients in latitude in the nearest inner spiral arm, similar to those found by other observations in different regions. Maximum velocity change is about 10 km s -1 for l=337degree. By generating synthetic line profiles constructed from a model spiral arm, several possible causes of these ''rolling motions'' were studied, such as a vertical displacement or a tilt of the arm (which failed to account for the observations) and rotation or shearing in the arm. It was futher shown that a typical arm can maintain such a motion (approx. =75 km s -1 kpc -1 ) with its own gravitational potential. The results are used to study the origin and tilt of Gould's Belt

Heavy-Duty Low-Temperature and Diesel Combustion & Heavy-Duty Combustion Modeling

Energy Technology Data Exchange (ETDEWEB)

Musculus, Mark P. [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

2017-11-01

Regulatory drivers and market demands for lower pollutant emissions, lower carbon dioxide emissions, and lower fuel consumption motivate the development of clean and fuel-efficient engine operating strategies. Most current production engines use a combination of both in-cylinder and exhaust emissions-control strategies to achieve these goals. The emissions and efficiency performance of in-cylinder strategies depend strongly on flow and mixing processes associated with fuel injection. Various diesel engine manufacturers have adopted close-coupled post-injection combustion strategies to both reduce pollutant emissions and to increase engine efficiency for heavy-duty applications, as well as for light- and medium-duty applications. Close-coupled post-injections are typically short injections that follow a larger main injection in the same cycle after a short dwell, such that the energy conversion efficiency of the post-injection is typical of diesel combustion. Of the various post-injection schedules that have been reported in the literature, effects on exhaust soot vary by roughly an order of magnitude in either direction of increasing or decreasing emissions relative to single injections (O’Connor et al., 2015). While several hypotheses have been offered in the literature to help explain these observations, no clear consensus has been established. For new engines to take full advantage of the benefits that post-injections can offer, the in-cylinder mechanisms that affect emissions and efficiency must be identified and described to provide guidance for engine design.

2017-02-01

The purpose of the study was to determine if forearm blood pressures (BPs) measured in three different locations agree with the recommended upper arm location for noninvasive BP measurement. A method-comparison design was used. In a convenience sample of postanesthesia care unit patients with large upper arm circumference, BP's were obtained in three different forearm locations (lower forearm, middle forearm, and upper forearm) and compared to upper arm BP using an automated BP measuring device. The level of agreement (bias ± precision) between each forearm location and the upper arm BP was calculated using standard formulas. Acceptable levels of agreement based on expert opinion were set a priori at bias and precision values of less than ±5 mm Hg (bias) and ±8 mm Hg (precision). Forty-eight postanesthesia patients participated in the study. Bias and precision values were found to exceed the acceptable level of agreement for all but one of the systolic and diastolic BP comparisons in the three forearm BP locations. Fifty-six percent of all patients studied had one or more BP difference of at least 10 mm Hg in each of the three forearm locations, with 10% having one or more differences of at least 20 mm Hg. The differences in forearm BP measurements observed in this study indicate that the clinical practice of using a forearm BP with a regular-sized BP cuff in place of a larger sized BP cuff placed on the upper arm in postanesthesia care unit patients with large arm circumferences is inappropriate. The BPs obtained at the forearm location are not equivalent to the BPs obtained at the upper arm location. Copyright © 2015 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc.

Independent consultants : fiduciary duties, trade secrets and confidential information

International Nuclear Information System (INIS)

Fraser, B.; Wilhelmson, M.

1999-01-01

Because of cutbacks and downsizing within the petroleum industry, it has become one of the largest users of contract personnel to provide services that were previously provided by senior levels of management. This paper explored the application of common law fiduciary duties and the duty of confidence to the independent workforce. It examined to what extent fiduciary duties apply to independent consultants and the best way for the employer to protect itself from the potential misuse of confidential information. Part 1 of the paper described fiduciary duties. A fiduciary relationship was described as one that possesses the following three characteristics: (1) the fiduciary has scope for the exercise of some discretion of power, (2) the fiduciary can unilaterally exercise that power to affect the beneficiary's practical interests, and (3) the beneficiary is peculiarly vulnerable to the fiduciary holding the discretion of power. Three examples of how the courts treated some arguments regarding fiduciaries were presented. Part 2 of this paper discussed how trade secrets and confidential information should be handled. It was explained, that regardless of fiduciary duties, the unauthorized use of confidential information by an independent contractor can give rise to liability and an award of damages by the courts. Some examples where the Supreme Court of Canada found breach of confidence by a party were presented. Information communicated from an employer to an employee can be divided into the following three categories: (1) publicly accessible and not confidential, (2) confidential and must be treated as such while an employee is employed, but if learned becomes part of the employees skill and knowledge, and (3) specific confidential trade secrets that cannot lawfully be used for anyone's benefit but the employer's. Issues regarding defining rights and obligations by contract were also discussed

Numerous studies document higher substance use among military men after deployment; similar studies focused on military women are limited. This study examines alcohol use of active duty women and deployment factors, social/environmental/attitudinal factors, and psychological/intrapersonal factors. Secondary data analysis of the 2011 Survey of Health-Related Behavior of active duty military personnel was conducted using bivariate statistics and multiple regression analyses with Alcohol Use Disorders Identification Test scores as the dependent variable. Nearly 94% had low risk for alcohol use disorders. Length of combat experience and extent of combat exposure were unrelated to Alcohol Use Disorders Identification Test scores; noncombat deployment was unrelated after controlling for marital status, age of first drink, pay grade, and branch of service. Significant motivators (p risk propensity, lifetime prevalence of suicidal ideation, and depressed mood were significant predictors in the regression model after controlling for covariates. Findings suggest that some active duty women use alcohol to cope with adverse emotional states, whereas others use alcohol consistent with propensity for high-risk behaviors.

DePasquale, Nicole; Davis, Kelly D; Zarit, Steven H; Moen, Phyllis; Hammer, Leslie B; Almeida, David M

2016-03-01

Women who combine formal and informal caregiving roles represent a unique, understudied population. In the literature, healthcare employees who simultaneously provide unpaid elder care at home have been referred to as double-duty caregivers. The present study broadens this perspective by examining the psychosocial implications of double-duty child care (child care only), double-duty elder care (elder care only), and triple-duty care (both child care and elder care or "sandwiched" care). Drawing from the Work, Family, and Health Study, we focus on a large sample of women working in nursing homes in the United States (n = 1,399). We use multiple regression analysis and analysis of covariance tests to examine a range of psychosocial implications associated with double- and triple-duty care. Compared with nonfamily caregivers, double-duty child caregivers indicated greater family-to-work conflict and poorer partner relationship quality. Double-duty elder caregivers reported more family-to-work conflict, perceived stress, and psychological distress, whereas triple-duty caregivers indicated poorer psychosocial functioning overall. Relative to their counterparts without family caregiving roles, women with combined caregiving roles reported poorer psychosocial well-being. Additional research on women with combined caregiving roles, especially triple-duty caregivers, should be a priority amidst an aging population, older workforce, and growing number of working caregivers. © The Author 2014.

Engelberger, J. F.; Roberts, W. Nelson; Ryan, David J.; Silverthorne, Andrew

2004-01-01

The Anthropomorphic Robotic Testbed (ART) is an experimental prototype of a partly anthropomorphic, humanoid-size, mobile robot. The basic ART design concept provides for a combination of two-armed coordination, tactility, stereoscopic vision, mobility with navigation and avoidance of obstacles, and natural-language communication, so that the ART could emulate humans in many activities. The ART could be developed into a variety of highly capable robotic assistants for general or specific applications. There is especially great potential for the development of ART-based robots as substitutes for live-in health-care aides for home-bound persons who are aged, infirm, or physically handicapped; these robots could greatly reduce the cost of home health care and extend the term of independent living. The ART is a fully autonomous and untethered system. It includes a mobile base on which is mounted an extensible torso topped by a head, shoulders, and two arms. All subsystems of the ART are powered by a rechargeable, removable battery pack. The mobile base is a differentially- driven, nonholonomic vehicle capable of a speed >1 m/s and can handle a payload >100 kg. The base can be controlled manually, in forward/backward and/or simultaneous rotational motion, by use of a joystick. Alternatively, the motion of the base can be controlled autonomously by an onboard navigational computer. By retraction or extension of the torso, the head height of the ART can be adjusted from 5 ft (1.5 m) to 6 1/2 ft (2 m), so that the arms can reach either the floor or high shelves, or some ceilings. The arms are symmetrical. Each arm (including the wrist) has a total of six rotary axes like those of the human shoulder, elbow, and wrist joints. The arms are actuated by electric motors in combination with brakes and gas-spring assists on the shoulder and elbow joints. The arms are operated under closed-loop digital control. A receptacle for an end effector is mounted on the tip of the wrist and

A demand system model differentiating goods by origin is developed to examine impacts of duty drawback on U.S. orange juice exports and prices. An empirical analysis suggests that on average duty drawback has increased annual orange juice exports by about 16.5 million SSE gallons or 11% of export sales, and has supported the U.S. price of orange juice by about 2 cents per gallon. Not all benefits of duty drawback go to exporters. Importers who own drawback credits but do not export product ma...

Study of the impacts of regulations affecting the acceptance of Integrated Community Energy Systems: public utility, energy facility siting and municipal franchising regulatory programs in North Dakota. Preliminary background report

Energy Technology Data Exchange (ETDEWEB)

Feurer, D A; Weaver, C L; Gallagher, K C; Hejna, D; Rielley, K J

1980-01-01

The North Dakota Public Service Commission (PSC) is a constitutional body responsible for the regulation of all public utilities. The PSC is composed of three elected commissioners who serve for six year terms. Section 83 of the state's Constitution gives the legislature the power to prescribe the powers and duties of the PCS. Pursuant to this authorization, the legislature adopted Title 49 of the North Dakota Century Code prescribing the jurisdiction as well as the powers and duties of the PSC. It also prescribes various rules and regulations pertaining to electric, gas, and other public utilities. All authority over public utilities is vested in the PSC. Local governments, except for the powers inherent in their franchising and zoning authority, are not given any control over utility regulation. Public utility regulatory statutes, energy facility siting programs, and municipal franchising authority are examined to identify how they may impact on the ability of an organization, whether or not it be a regulated utility, to construct and operate an ICES.

To evaluate whether inter-arm diastolic blood pressure difference (DBPl-r) induced by one arm ischemia correlates with flow-mediated dilatation (FMD). Bilateral arm BPs were simultaneously measured with two automatic devices and right brachial artery diameter (D) was measured by ultrasound technique in 108 subjects (56 hypertensives and 52 normotensives). Following baseline diameter (D0) and BP measurement, right brachial artery was occluded for 5 minutes. The diameter was measured at 1, 1.5 and 2 min, and bilateral BPs measured at 3, 4 and 5 min after occlusion release. Their averages were recorded as post-D and post-BP, respectively. The difference between post-D and D0 (ΔD) was calculated as the percentage increase of artery diameter (ΔD/D0). The BP difference between left and right arms was calculated as BPl-r, and the difference of post- BPl-r and baseline BPl-r was recorded as the net change of BPl-r (ΔBPl-r). At baseline, bilateral SBPs and DBPs were similar. Right arm ischemia induced significant DBP decline only in the right arm (68.8±12.7 vs 72.6±12.0 mmHg, Parm DBP difference induced by one arm ischemia may be a potential index for clinical evaluation of vascular endothelial function.

However, the dynamic coupling between the arms and the base will have a serious impact on the spacecraft attitude and the hand motion of each arm. Instead of considering one arm as the mission arm and the other as the balance arm, in this work two arms of the space robot perform as mission arms aimed at accomplishing secure capture of a floating target. The paper investigates coordinated control of the base's attitude and the arms' motion in the task space in the presence of system uncertainties. Two types of controllers, i.e. a Sliding Mode Controller (SMC) and a nonlinear Model Predictive Controller (MPC) are verified and compared with a conventional Computed-Torque Controller (CTC) through numerical simulations in terms of control accuracy and system robustness. Both controllers eliminate the need to linearly parameterize the dynamic equations. The MPC has been shown to achieve performance with higher accuracy than CTC and SMC in the absence of system uncertainties under the condition that they consume comparable energy. When the system uncertainties are included, SMC and CTC present advantageous robustness than MPC. Specifically, in a case where system inertia increases, SMC delivers higher accuracy than CTC and costs the least amount of energy.

Muscle weakness in the extensors poststroke is a common motor impairment. Unfortunately, research is unclear on whether bilateral movements increase extensor force production in the paretic arm. This study investigated sustained force production while stroke individuals maximally extended their wrist and fingers on their paretic arm. Specifically, we determined isometric force production in three conditions: (a) unilateral paretic arm, (b) unilateral nonparetic arm, and (c) bilateral (both arms executing the same movement simultaneously). Seventeen chronic stroke patients produced isometric sustained force by executing wrist and fingers extension in unilateral and bilateral contraction conditions. Mean force, force variability (coefficient of variation), and signal-to-noise ratio were calculated for each contraction condition. Analysis of two-way (Arm × Type of Condition: 2 × 2; Paretic or Nonparetic Arm × Unilateral or Bilateral Conditions) within-subjects ANOVAs revealed that the bilateral condition increased sustained force in the paretic arm, but reduced sustained force in the nonparetic arm. Further, although the paretic arm exhibited more force variability and less signal-to-noise ratio than the nonparetic arm during a unilateral condition, there were no differences when participants simultaneously executed isometric contractions with both arms. Our unique findings indicate that bilateral contractions transiently increased extensor force in the paretic arm. Implications for Rehabilitation Bilateral movements increased isometric wrsit extensor force in paretic arms and redcued force in nonparetic arms versus unilateral movements. Both paretic and nonparetic arms produced similar force variability and signal-to-noise ratio during bilateral movements. Increased sustained force in the paretic arm during the bilateral condition indicates that rehabilitation protocols based on bilateral movements may be beneficial for functional recovery.

Blood pressure (BP) recordings often differ between arms, but the extent to which these differences are reproducible and whether the differences have prognostic importance is unknown. We enrolled 421 consecutive patients from a medicine and a renal clinic at a veterans' hospital. Three BP recordings were obtained in each arm using an oscillometric device in a sequential manner and repeated in 1 week. Patients were followed for all-cause mortality arm had 5.1-mm Hg higher systolic BP that attenuated by approximately 2.2 mm Hg a week later. Systolic BP dropped 6.9 mm Hg over 1 week and by an additional 5.3 mm Hg in patients with chronic kidney disease. Accounting for the visit and arm effect improved the reproducibility of the BP measurements. The intraclass correlation coefficient was 0.74, which improved to 0.88 after accounting for visit and 0.93 after accounting for arm. The crude mortality rate was 6.33 per 100 patient-years. Every 10-mm Hg difference in systolic BP between the arms conferred a mortality hazard of 1.24 (95% CI: 1.01 to 1.52) after adjusting for average systolic BP and chronic kidney disease. BP differences between arms are reproducible and carry prognostic information. Patients should have evaluation of BP in both arms at the screening visit.

Nuclear Arms Race and Environment

This paper introduces a new factor, environment, into nuclear arms race model. In this model, nuclear weapons produce larger defense power compared with conventional arms, but hurt the environment meanwhile. In the global welfare maximum level, both conventional and nuclear weapons budget are zero. However, the competitive equilibrium may not achieve the optimum. I give the condition to jump out of the prisoner's dilemma.

Resident duty hours in Canada: a survey and national statement.

Physicians in general, and residents in particular, are adapting to duty schedules in which they have fewer continuous work hours; however, there are no Canadian guidelines on duty hours restrictions. To better inform resident duty hour policy in Canada, we set out to prepare a set of recommendations that would draw upon evidence reported in the literature and reflect the experiences of resident members of the Canadian Association of Internes and Residents (CAIR). A survey was prepared and distributed electronically to all resident members of CAIR. A total of 1796 eligible residents participated in the survey. Of those who responded, 38% (601) reported that they felt they could safely provide care for up to 16 continuous hours, and 20% (315) said that 12 continuous hours was the maximum period during which they could safely provide care (n=1592). Eighty-two percent (1316) reported their perception that the quality of care they had provided suffered because of the number of consecutive hours worked (n=1598). Only 52% (830) had received training in handover (n=1594); those who had received such training reported that it was commonly provided through informal modelling. On the basis of these data and the existing literature, CAIR recommends that resident duty hours be managed in a way that does not endanger the health of residents or patients; does not impair education; is flexible; and does not violate ethical or legal standards. Further, residents should be formally trained in handover skills and alternative duty hour models.

High duty cycle to low duty cycle: echolocation behaviour of the hipposiderid bat Coelops frithii.

Laryngeally echolocating bats avoid self-deafening (forward masking) by separating pulse and echo either in time using low duty cycle (LDC) echolocation, or in frequency using high duty cycle (HDC) echolocation. HDC echolocators are specialized to detect fluttering targets in cluttered environments. HDC echolocation is found only in the families Rhinolophidae and Hipposideridae in the Old World and in the New World mormoopid, Pteronotus parnellii. Here we report that the hipposiderid Coelops frithii, ostensibly an HDC bat, consistently uses an LDC echolocation strategy whether roosting, flying, or approaching a fluttering target rotating at 50 to 80 Hz. We recorded the echolocation calls of free-flying C. frithii in the field in various situations, including presenting bats with a mechanical fluttering target. The echolocation calls of C. frithii consisted of an initial narrowband component (0.5±0.3 ms, 90.6±2.0 kHz) followed immediately by a frequency modulated (FM) sweep (194 to 113 kHz). This species emitted echolocation calls at duty cycles averaging 7.7±2.8% (n = 87 sequences). Coelops frithii approached fluttering targets more frequently than did LDC bats (C.frithii, approach frequency  = 40.4%, n = 80; Myotis spp., approach frequency  = 0%, n = 13), and at the same frequency as sympatrically feeding HDC species (Hipposideros armiger, approach rate  = 53.3%, n = 15; Rhinolophus monoceros, approach rate  = 56.7%, n = 97). We propose that the LDC echolocation strategy used by C. frithii is derived from HDC ancestors, that this species adjusts the harmonic contents of its echolocation calls, and that it may use both the narrowband component and the FM sweep of echolocations calls to detect fluttering targets.

Planet-driven Spiral Arms in Protoplanetary Disks. I. Formation Mechanism

Science.gov (United States)

Bae, Jaehan; Zhu, Zhaohuan

2018-06-01

Protoplanetary disk simulations show that a single planet can excite more than one spiral arm, possibly explaining the recent observations of multiple spiral arms in some systems. In this paper, we explain the mechanism by which a planet excites multiple spiral arms in a protoplanetary disk. Contrary to previous speculations, the formation of both primary and additional arms can be understood as a linear process when the planet mass is sufficiently small. A planet resonantly interacts with epicyclic oscillations in the disk, launching spiral wave modes around the Lindblad resonances. When a set of wave modes is in phase, they can constructively interfere with each other and create a spiral arm. More than one spiral arm can form because such constructive interference can occur for different sets of wave modes, with the exact number and launching position of the spiral arms being dependent on the planet mass as well as the disk temperature profile. Nonlinear effects become increasingly important as the planet mass increases, resulting in spiral arms with stronger shocks and thus larger pitch angles. This is found to be common for both primary and additional arms. When a planet has a sufficiently large mass (≳3 thermal masses for (h/r) p = 0.1), only two spiral arms form interior to its orbit. The wave modes that would form a tertiary arm for smaller mass planets merge with the primary arm. Improvements in our understanding of the formation of spiral arms can provide crucial insights into the origin of observed spiral arms in protoplanetary disks.

Regulation of PDH in human arm and leg muscles at rest and during intense exercise

DEFF Research Database (Denmark)

Kiilerich, Kristian; Birk, Jesper Bratz; Damsgaard, Rasmus

2008-01-01

To test the hypothesis that pyruvate dehydrogenase (PDH) is differentially regulated in specific human muscles, regulation of PDH was examined in triceps, deltoid, and vastus lateralis at rest and during intense exercise. To elicit considerable glycogen use, subjects performed 30 min of exhaustive...... arm cycling on two occasions and leg cycling exercise on a third day. Muscle biopsies were obtained from deltoid or triceps on the arm exercise days and from vastus lateralis on the leg cycling day. Resting PDH protein content and phosphorylation on PDH-E1 alpha sites 1 and 2 were higher (P ....05) in vastus lateralis than in triceps and deltoid as was the activity of oxidative enzymes. Net muscle glycogen utilization was similar in vastus lateralis and triceps ( approximately 50%) but less in deltoid (likely reflecting less recruitment of deltoid), while muscle lactate accumulation was approximately...

Evaluation of arm-leg coordination in flat breaststroke.

Chollet, D; Seifert, L; Leblanc, H; Boulesteix, L; Carter, M

2004-10-01

This study proposes a new method to evaluate arm-leg coordination in flat breaststroke. Five arm and leg stroke phases were defined with a velocity-video system. Five time gaps quantified the time between arm and leg actions during three paces of a race (200 m, 100 m and 50 m) in 16 top level swimmers. Based on these time gaps, effective glide, effective propulsion, effective leg insweep and effective recovery were used to identify the different stroke phases of the body. A faster pace corresponded to increased stroke rate, decreased stroke length, increased propulsive phases, shorter glide phases, and a shorter T1 time gap, which measured the effective body glide. The top level swimmers showed short time gaps (T2, T3, T4, measuring the timing of arm-leg recoveries), which reflected the continuity in arm and leg actions. The measurement of these time gaps thus provides a pertinent evaluation of swimmers' skill in adapting their arm-leg coordination to biomechanical constraints.

C-arm tomosynthesis is a three dimensional imaging technique. Both x-ray source and the detector are mounted on a C-arm wheeled structure to provide wide variety of movement around the object. In this paper, C-arm tomosynthesis was introduced to provide three dimensional information over a limited view angle (less than 180o) to reduce radiation exposure and examination time. Reconstruction algorithms based on ray tracing method such as ray tracing back projection (BP), simultaneous algebraic reconstruction technique (SART) and maximum likelihood expectation maximization (MLEM) were developed for C-arm tomosynthesis. C-arm tomosynthesis projection images of simulated spherical object were simulated with a virtual geometric configuration with a total view angle of 40 degrees. This study demonstrated the sharpness of in-plane reconstructed structure and effectiveness of removing out-of-plane blur for each reconstruction algorithms. Results showed the ability of ray tracing based reconstruction algorithms to provide three dimensional information with limited angle C-arm tomosynthesis.

Kant’s concept of indirect duties and environmental ethics

Directory of Open Access Journals (Sweden)

Milene Consenso Tonetto

2017-12-01

Full Text Available The aim of this paper is to assess whether Kant’s moral theory is suitable to deal with our obligations to take care of nonhuman animals and the environment. Kant’s ethics distinguishes persons, that is, rational beings with unconditional values who are considered as ends in themselves, from things, which have only relative worth. In relation to nature as a whole and to nonrational beings, Kant argues that we have only indirect duties or duties with regard to them. According to some philosophers, Kant’s ethics has anthropocentric starting points which lead to speciesist conclusions. This paper will argue that indirect duties can be in accordance with nonhuman interests, such as the suffering of nonhuman animals, the preservation of species and ecosystems, and so on. Thus Kant’s moral philosophy may contribute to environmental ethics because it justifies at least animal welfare and environmental protections as constraints on unrestricted human action.

The Formulation Assessment and Support Team (FAST) for the Asteroid Redirect Mission (ARM) was a two-month effort, chartered by NASA, to provide timely inputs for mission requirement formulation in support of the Asteroid Redirect Robotic Mission (ARRM) Requirements Closure Technical Interchange Meeting held December 15-16, 2015. Additionally, the FAST was tasked with developing an initial list of potential mission investigations and providing input on potential hosted payloads and partnerships. The FAST explored several aspects of potential science benefits and knowledge gain from the ARM. Expertise from the science, engineering, and technology communities was represented in exploring lines of inquiry related to key characteristics of the ARRM reference target asteroid (2008 EV5) for engineering design purposes. Specific areas of interest included target origin, spatial distribution and size of boulders, surface geotechnical properties, boulder physical properties, and considerations for boulder handling, crew safety, and containment. In order to increase knowledge gain potential from the mission, opportunities for partnerships and accompanying payloads that could be provided by domestic and international partners were also investigated. The ARM FAST final report was publicly released on February 18, 2016 and represents the FAST's final product. The report and associated public comments are being used to support mission requirements formulation and serve as an initial inquiry to the science and engineering communities relating to the characteristics of the ARRM reference target asteroid. This report also provides a suggested list of potential investigations sorted and grouped based on their likely benefit to ARM and potential relevance to NASA science and exploration goals. These potential investigations could be conducted to reduce mission risks and increase knowledge return in the areas of science, planetary defense, asteroid resources and in-situ resource

To explore, describe and compare learning actions that nursing students used during peripheral vein cannulation training on a latex arm or each other's arms in a clinical skills centre. Simulation-based training is thought to enhance learning and transfer of learning from simulation to the clinical setting and is commonly recommended in nursing education. What students actually are doing during simulation-based training is, however, less explored. The analysis of learning actions used during simulation-based training could contribute to development and improvement of simulation as a learning strategy in nursing education. A qualitative explorative and descriptive research design, involving content analysis of video recordings, was used. Video-supported observation of nine nursing students practicing vein cannulation was conducted in a clinical skills centre in late 2012. The students engaged in various learning actions. Students training on a latex arm used a considerably higher number of learning actions relative to those training on each other's arms. In both groups, students' learning actions consisted mainly of seeking and giving support. The teacher provided students training on each other's arms with detailed feedback regarding insertion of the cannula into the vein, while those training on a latex arm received sparse feedback from the teacher and fellow students. The teacher played an important role in facilitating nursing students' practical skill learning during simulation. The provision of support from both teachers and students should be emphasised to ensure that nursing students' learning needs are met. This study suggest that student nurses may be differently and inadequately prepared in peripheral vein cannulation in two simulation modalities used in the academic setting; training on a latex arm and on each other's arms. © 2017 John Wiley & Sons Ltd.

Duty hours as viewed through a professionalism lens.

Science.gov (United States)

Ginsburg, Shiphra

2014-01-01

Understanding medical professionalism and its evaluation is essential to ensuring that physicians graduate with the requisite knowledge and skills in this domain. It is important to consider the context in which behaviours occur, along with tensions between competing values and the individual’s approach to resolving such conflicts. However, too much emphasis on behaviours can be misleading, as they may not reflect underlying attitudes or professionalism in general. The same behaviour can be viewed and evaluated quite differently, depending on the situation. These concepts are explored and illustrated in this paper in the context of duty hour regulations. The regulation of duty hours creates many conflicts that must be resolved, and yet their resolution is often hidden, especially when compliance with or violation of regulations carries significant consequences. This article challenges attending physicians and the medical education community to reflect on what we value in our trainees and the attributions we make regarding their behaviours. To fully support our trainees’ development as professionals, we must create opportunities to teach them the valuable skills they will need to achieve balance in their lives. [P]rofessionalism has no meaningful existence independent of the interactions that give it form and meaning. There is great folly in thinking otherwise. Hafferty and Levinson (2008)[1] Understanding and evaluating professionalism is essential to excellence in medical education and is mandated by organizations that oversee medical training [2]. Historically, attention has been focused largely on the professionalism of individual students or residents, at least for the purposes of evaluation. Yet there is now a growing appreciation that professionalism can be defined, understood, and evaluated from multiple perspectives [3]. Importantly, context has been recognized as critical to shaping trainees’ behaviours, and hence as important to our understanding of

Full Text Available The claim according to which corporations are morally responsible is a controversial one. At the same time, it is nowadays common to assign moral duties to companies, especially in work confronting the business and human rights issue. Can companies bear moral duties without being morally responsible? This article presents three different accounts of the duty to follow the course of action with the best consequences (consequentialist duty. The ascription of that duty to business is compatible with the claim that, by not being volitional agents, companies are not morally responsible for anything they do. The paper also addresses two possible objections against the claim that companies bear the duty of taking the course of action with the best consequences. These objections state that corporations are incapable of acting, be it in a general way (i.e. corporations do not possess the moral status of agents, be it regarding particular acts (the objection grounded on the “ought” implies “can” maxim.

The octopus arm is a muscular hydrostat and due to its deformable and highly flexible structure it is capable of a rich repertoire of motor behaviors. Its motor control system uses planning principles and control strategies unique to muscular hydrostats. We previously reconstructed a data set of octopus arm movements from records of natural movements using a sequence of 3D curves describing the virtual backbone of arm configurations. Here we describe a novel representation of octopus arm movements in which a movement is characterized by a pair of surfaces that represent the curvature and torsion values of points along the arm as a function of time. This representation allowed us to explore whether the movements are built up of elementary kinematic units by decomposing each surface into a weighted combination of 2D Gaussian functions. The resulting Gaussian functions can be considered as motion primitives at the kinematic level of octopus arm movements. These can be used to examine underlying principles of movement generation. Here we used combination of such kinematic primitives to decompose different octopus arm movements and characterize several movement prototypes according to their composition. The representation and methodology can be applied to the movement of any organ which can be modeled by means of a continuous 3D curve.

Effective procedures have been developed, using national technical measures (photoreconnaissance satellites, radiointercept stations, etc.), for verification of reductions in land-based intercontinental ballistic missiles, such as marine-based ballistic missiles, and strategic bombers. However, there is agreement on procedures for verifying limitations of numbers of long-range nuclear-armed cruise missiles. The difficulties in developing such procedures are sometimes regarded (by opponents of nuclear disarmament) as a reason why cruise missiles based on ships and submarines ought not to be limited by future arms-reduction treaties. This paper considers the detectability of nuclear-armed cruise missiles through the penetrating radiation emitted spontaneously from their warheads

Determination of the duty cycle of WLAN for realistic radio frequency electromagnetic field exposure assessment.

Wireless Local Area Networks (WLANs) are commonly deployed in various environments. The WLAN data packets are not transmitted continuously but often worst-case exposure of WLAN is assessed, assuming 100% activity and leading to huge overestimations. Actual duty cycles of WLAN are thus of importance for time-averaging of exposure when checking compliance with international guidelines on limiting adverse health effects. In this paper, duty cycles of WLAN using Wi-Fi technology are determined for exposure assessment on large scale at 179 locations for different environments and activities (file transfer, video streaming, audio, surfing on the internet, etc.). The median duty cycle equals 1.4% and the 95th percentile is 10.4% (standard deviation SD = 6.4%). Largest duty cycles are observed in urban and industrial environments. For actual applications, the theoretical upper limit for the WLAN duty cycle is 69.8% and 94.7% for maximum and minimum physical data rate, respectively. For lower data rates, higher duty cycles will occur. Although counterintuitive at first sight, poor WLAN connections result in higher possible exposures. File transfer at maximum data rate results in median duty cycles of 47.6% (SD = 16%), while it results in median values of 91.5% (SD = 18%) at minimum data rate. Surfing and audio streaming are less intensively using the wireless medium and therefore have median duty cycles lower than 3.2% (SD = 0.5-7.5%). For a specific example, overestimations up to a factor 8 for electric fields occur, when considering 100% activity compared to realistic duty cycles. Copyright © 2012 Elsevier Ltd.

Control of octopus arm extension by a peripheral motor program.

Science.gov (United States)

Sumbre, G; Gutfreund, Y; Fiorito, G; Flash, T; Hochner, B

2001-09-07

For goal-directed arm movements, the nervous system generates a sequence of motor commands that bring the arm toward the target. Control of the octopus arm is especially complex because the arm can be moved in any direction, with a virtually infinite number of degrees of freedom. Here we show that arm extensions can be evoked mechanically or electrically in arms whose connection with the brain has been severed. These extensions show kinematic features that are almost identical to normal behavior, suggesting that the basic motor program for voluntary movement is embedded within the neural circuitry of the arm itself. Such peripheral motor programs represent considerable simplification in the motor control of this highly redundant appendage.

Randomised controlled trials (RCTs) are considered the 'gold-standard' for evaluating medical treatments. However, patients and clinicians report difficulties with informed consent and recruitment. We evaluated the utility of a Decision Aid (DA) in reducing RCT-related decisional conflict, and improving RCT knowledge and recruitment. Potential participants for a radiotherapy RCT were invited to participate in the current study. Participants were randomised to receive the RCT's participant information sheet with or without a DA. Questionnaires were administered at baseline, one and six months. The primary outcome measure was decisional conflict. Secondary outcome measures included knowledge regarding and recruitment to the RCT. 129 men were randomised to the DA (63) and control (66) arms. Decisional conflict was significantly lower over 6-months (p=0.048) in the DA arm. Knowledge regarding the RCT was significantly higher at 6months (p=0.033) in the DA arm. 20.6% of the DA arm (13 of 63) and 9% of the control arm (6 of 66) entered the RCT. This study demonstrates the utility of a DA in reducing decisional conflict and improving trial knowledge in men with cancer who are making decisions regarding RCT participation.

Optimizing Armed Forces Capabilities for Hybrid Warfare – New Challenge for Slovak Armed Forces

Directory of Open Access Journals (Sweden)

Peter PINDJÁK

2015-09-01

Full Text Available The paper deals with the optimization of military capabilities of the Slovak Armed Forces for conducting operations in a hybrid conflict, which represents one of the possible scenarios of irregular warfare. Whereas in the regular warfare adversaries intend to eliminate the centers of gravity of each other, most often command and control structures, in irregular conflicts, the center of gravity shifts towards the will and cognitive perception of the target population. Hybrid warfare comprises a thoroughly planned combination of conventional military approaches and kinetic operations with subversive, irregular activities, including information and cyber operations. These efforts are often accompanied by intensified activities of intelligence services, special operation forces, and even mercenary and other paramilitary groups. The development of irregular warfare capabilities within the Slovak Armed Forces will require a progressive transformation process that may turn the armed forces into a modern and adaptable element of power, capable of deployment in national and international crisis management operations.

Is it the duty of every citizen to participate in clinical research?

Directory of Open Access Journals (Sweden)

Fermín Roland Schramm

2012-06-01

Full Text Available The complex phenomenon of globalization, considered by many as the main feature of contemporary societies, is not without contradictions and questions of type analítico-conceptual, as well as ethics and policies. At least three kinds of interpretations of the phenomenon can be distinguished in this sense: as a continuity, understood as development and radicalization of the contents of modernity; as a break in relation to it; or as a hybridization between rupture and continuity. It is in this dialectical context in a globalized world, which must become the question of whether or not there is the moral duty of every citizen to participate in a research involving human beings. But to answer argumentativamente satisfactorily, the meaning of these possible new duties of the citizen, required by the world system in rapidly changing and ever should be discussed. This system is at the same time more integrated and more differentiated - and indicated by the polysemic words globalization and citizenship-, considering that this type of duties involve, in principle, the improvement of the State of health and well-being of individuals and populations, but that they can also involve ethically and politically questionable effects, these duties shall be considered as being only duties prima facie.

TNO regularly performs measurements to determine the in-service performance and durability with respect to the pollutant emissions of heavy-duty vehicles under representative driving conditions. The 2011 measurement programme yields new insights regarding the emission performance of the upcoming Euro VI technology for heavy-duty vehicles, mandatory as of 31 December 2013 and, together with the results from earlier performed programmes, leads to conclusions on the emission performance of past and present generations of heavy-duty vehicles (Euro V, EEV)

In this study, C-Arm equipment is being used as we intend to verify the exposure dose on the operator by the scattering rays during the operation of the C-Arm equipment and to provide an effective method of reducing the exposure dose. Exposure dose is less than the Over Tube method utilizes the C-arm equipment Under Tube the scheme, The result showed that the exposure dose on the operator decreased with a thicker shield, and as the operator moved away from the center line. Moreover, as the research time prolongated, the exposure dose increased, and among the three affixed location of the dosimeter, the most exposure dose was measured at gonadal, then followed by chest and thyroid. However, in consideration of the relationship between the operator and the patient, the distance cannot be increased infinitely and the research time cannot be decreased infinitely in order to reduce the exposure dose. Therefore, by changing the thickness of the radiation shield, the exposure dose on the operator was able to be reduced. If you are using a C-Arm equipment discomfort during surgery because the grounds that the procedure is neglected and close to the dose of radiation shielding made can only increase. Because a separate control room cannot be used for the C-Arm equipment due to its characteristic, the exposure dose on the operator needs to be reduced by reinforcing the shield through an appropriate thickness of radiation shield devices, such as apron, etc. during a treatment.

Kinematic decomposition and classification of octopus arm movements

Directory of Open Access Journals (Sweden)

Ido eZelman

2013-05-01

Full Text Available The octopus arm is a muscular hydrostat and due to its deformable and highly flexible structure it is capable of a rich repertoire of motor behaviors. Its motor control system uses planning principles and control strategies unique to muscular hydrostats. We previously reconstructed a data set of octopus arm movements from records of natural movements using a sequence of 3D curves describing the virtual backbone of arm configurations. Here we describe a novel representation of octopus arm movements in which a movement is characterized by a pair of surfaces that represent the curvature and torsion values of points along the arm as a function of time. This representation allowed us to explore whether the movements are built up of elementary kinematic units by decomposing each surface into a weighted combination of 2D Gaussian functions. The resulting Gaussian functions can be considered as motion primitives at the kinematic level of octopus arm movements. These can be used to examine underlying principles of movement generation. Here we used combination of such kinematic primitives to decompose different octopus arm movements and characterize several movement prototypes according to their composition. The representation and methodology can be applied to the movement of any organ which can be modeled by means of a continuous 3D curve.

ATLAS software stack on ARM64

CERN Document Server

Smith, Joshua Wyatt; The ATLAS collaboration

2016-01-01

The ATLAS experiment explores new hardware and software platforms that, in the future, may be more suited to its data intensive workloads. One such alternative hardware platform is the ARM architecture, which is designed to be extremely power efficient and is found in most smartphones and tablets. CERN openlab recently installed a small cluster of ARM 64-bit evaluation prototype servers. Each server is based on a single-socket ARM 64-bit system on a chip, with 32 Cortex-A57 cores. In total, each server has 128 GB RAM connected with four fast memory channels. This paper reports on the port of the ATLAS software stack onto these new prototype ARM64 servers. This included building the "external" packages that the ATLAS software relies on. Patches were needed to introduce this new architecture into the build as well as patches that correct for platform specific code that caused failures on non-x86 architectures. These patches were applied such that porting to further platforms will need no or only very little adj...

Does "hidden undercuffing" occur among obese patients? Effect of arm sizes and other predictors of the difference between wrist and upper arm blood pressures.

Science.gov (United States)

Doshi, Hardik; Weder, Alan B; Bard, Robert L; Brook, Robert D

2010-02-01

Arm size can affect the accuracy of blood pressure (BP) measurement, and "undercuffing" of large upper arms is likely to be a growing problem. Therefore, the authors investigated the relationship between upper arm and wrist readings. Upper arm and wrist circumferences and BP were measured in 261 consecutive patients. Upper arm auscultation and wrist BP was measured in triplicate, rotating measurements every 30 seconds between sites. Upper arm BP was 131.9+/-20.6/71.6+/-12.6 mm Hg in an obese population (body mass index, 30.6+/-6.6 kg/m(2)) with mean upper arm size of 30.7+/-5.1 cm. Wrist BP was higher (2.6+/-9.2 mm Hg and 4.9+/-6.6 mm Hg, respectively, PBlood Pressure (JNC 7) strata (kappa value=0.27-0.71), and the difference was >or=5 mm Hg in 72% of the patients. The authors conclude that there was poor concordance between arm and wrist BP measurement and found no evidence that "hidden undercuffing" was associated with obesity; therefore, they do not support routine use of wrist BP measurements.

Arms control, nonproliferation, and US national security

International Nuclear Information System (INIS)

Pilat, J.F.

1985-01-01

The continuation of the arms race and the failure of arms control and disarmament negotiations lend support to the belief that US and Soviet power, prestige, and security depend upon nuclear weapons. Therefore, the argument goes, the non-nuclear-weapon states (particularly those that are not allied with nuclear-weapon states and do not share their nuclear shield) may conclude that they would be well served by possession of these weapons. In this sense, the failure of nuclear arms reductions could create incentives for further proliferation

Lu, Lisa H; Cooper, Doug B; Reid, Matthew W; Khokhar, Bilal; Tsagaratos, Jennifer E; Kennedy, Jan E

2018-03-28

To compare symptom reporting patterns of service members with a history of concussion based on work status: full duty, limited duty, or in the Medical Evaluation Board (MEB)/disability process. Retrospective analysis of 181 service members with a history of concussion (MEB n = 56; limited duty n = 62; full duty n = 63). Neurobehavioral Symptom Inventory (NSI) Validity-10 cutoff (>22) and Mild Brain Injury Atypical Symptoms Scale (mBIAS) cutoffs (≥10 and ≥8) were used to evaluate potential over-reporting of symptoms. The MEB group displayed significantly higher NSI scores and significantly higher proportion scored above the mBIAS ≥10 cutoff (MEB = 15%; limited duty = 3%; full duty = 5%). Validity-10 cutoff did not distinguish between groups. MEB but not limited duty status was associated with increased risk of over-reporting symptoms in service members with a history of concussion. Results support the use of screening measures for over-reporting in the MEB/disability samples.

Stellar complexes in spiral arms of galaxies

Science.gov (United States)

Efremov, Yu. N.

The history of the introduction and development of the star complexes conception is briefly described. These large groups of stars were picked out and named as such ones in our Galaxy with argumentation and evidence for their physical unity (using the Cepheid variables the distances and ages of which are easy determined from their periods); anyway earlier the complexes were noted along the spiral arms of the Andromeda galaxy, but were not recognized as a new kind of star group. The chains of complexes along the spiral arms are observed quite rarely; their origin is explained by magneto- gravitational or purely gravitational instability developing along the arm. It is not clear why these chains are quite a rare phenomenon - and more so why sometimes the regular chain of complexes are observed in one arm only. Probably intergalactic magnetic field participated in formation of such chains. Apart from the complexes located along the arms, there are isolated giant complexes known (up to 700 pc in diameter) which look like super-gigantic but rather rarefied globular clusters. Until now only two of these formations are studied, in NGC 6946 and M51.

Duty to warn of genetic harm in breach of patient confidentiality.

Science.gov (United States)

Keeling, Sharon L

2004-11-01

Harm caused by the failure of health professionals to warn an at-risk genetic relative of her or his risk is genetic harm. Genetic harm should be approached using the usual principles of negligence. When these principles are applied, it is shown that (a) genetic harm is foreseeable; (b) the salient features of vulnerability, the health professional's knowledge of the risk to the genetic relative and the determinancy of the affected class and individual result in a duty of care being owed to the genetic relative; (c) the standard of care required to fulfil the duty to warn should be the expectations of a reasonable person in the position of the relative; and (d) causation is satisfied as the harm is caused by the failure of intervention of the health professional. Legislation enacted subsequent to the Report of the Commonwealth of Australia, Panel of Eminent Persons (Chair D Ipp), Review of the Law of Negligence Report (2002) and relevant to a duty to warn of genetic harm is considered. The modes of regulation and penalties for breach of any future duty to warn of genetic harm are considered.

3D Measurement of Forearm and Upper Arm during Throwing Motion using Body Mounted Sensor

Science.gov (United States)

Koda, Hideharu; Sagawa, Koichi; Kuroshima, Kouta; Tsukamoto, Toshiaki; Urita, Kazutaka; Ishibashi, Yasuyuki

The aim of this study is to propose the measurement method of three-dimensional (3D) movement of forearm and upper arm during pitching motion of baseball using inertial sensors without serious consideration of sensor installation. Although high accuracy measurement of sports motion is achieved by using optical motion capture system at present, it has some disadvantages such as the calibration of cameras and limitation of measurement place. Whereas the proposed method for 3D measurement of pitching motion using body mounted sensors provides trajectory and orientation of upper arm by the integration of acceleration and angular velocity measured on upper limb. The trajectory of forearm is derived so that the elbow joint axis of forearm corresponds to that of upper arm. Spatial relation between upper limb and sensor system is obtained by performing predetermined movements of upper limb and utilizing angular velocity and gravitational acceleration. The integration error is modified so that the estimated final position, velocity and posture of upper limb agree with the actual ones. The experimental results of the measurement of pitching motion show that trajectories of shoulder, elbow and wrist estimated by the proposed method are highly correlated to those from the motion capture system within the estimation error of about 10 [%].

Three factors in the international system have been of importance for the trade of arms: the role of the main actors on the supply side and since 1970 on the demand side, the permanently increasing importance of economics, and the balance trade, industrial capacity and jobs in supplier countries and purchasing power of potential importers. Two political events in 1991 had lasting effect on the development of the trade in arms: the dissolution of Soviet Union and the Gulf War

Driving pockels cells in multi-arm lasers

1978-01-01

This paper describes the method used to drive Pockels cells on the 20-arm Shiva laser for inertial confinement fusion research at the Lawrence Livermore Laboratory. Shiva became operational last fall, and has just completed a series of 20-arm target shots. It uses two pockels cell gates in each laser arm for suppression of amplified spontaneous emission (ASE) that can damage or destroy the target before the main pulse arrives. Two additional Pockels cells are used in the preamplification stages, so that a total of 42 cells must be driven by the pulser system

On-road heavy-duty diesel particulate matter emissions modeled using chassis dynamometer data.

Science.gov (United States)

Kear, Tom; Niemeier, D A

2006-12-15

This study presents a model, derived from chassis dynamometer test data, for factors (operational correction factors, or OCFs) that correct (g/mi) heavy-duty diesel particle emission rates measured on standard test cycles for real-world conditions. Using a random effects mixed regression model with data from 531 tests of 34 heavy-duty vehicles from the Coordinating Research Council's E55/E59 research project, we specify a model with covariates that characterize high power transient driving, time spent idling, and average speed. Gram per mile particle emissions rates were negatively correlated with high power transient driving, average speed, and time idling. The new model is capable of predicting relative changes in g/mi on-road heavy-duty diesel particle emission rates for real-world driving conditions that are not reflected in the driving cycles used to test heavy-duty vehicles.

Duty and role of Nuclear Regulation Authority facing a crucial moment

International Nuclear Information System (INIS)

Asaoka, Mie

2013-01-01

Duty of Nuclear Regulation Authority (NRA) was to restore public trust on nuclear regulation spoiled by the Fukushima nuclear accident. How applied such regulation as mandatory back-fitting based on latest knowledge and 40 year operational limit in principle became of great concern. Active faults issue on existing nuclear power station could be a touchstone. Safety side judgment and electric utilities side's proof responsibilities were required as more stringent criteria for active faults. The expert group had been working on assessment of fracture zones under the field survey. Reform of safety regulations should be done based on three important standpoints: (1) not business easiness but public safety was first (2) NRA keeping stance to judge its own safety standard and how NRA ought to be and (3) importance of public disclosure of information and participation in decision-making judging from greatness of public effects caused by nuclear disaster.

2009-03-01

Idle emissions data from 19 medium heavy-duty diesel and gasoline trucks are presented in this paper. Emissions from these trucks were characterized using full-flow exhaust dilution as part of the Coordinating Research Council (CRC) Project E-55/59. Idle emissions data were not available from dedicated measurements, but were extracted from the continuous emissions data on the low-speed transient mode of the medium heavy-duty truck (MHDTLO) cycle. The four gasoline trucks produced very low oxides of nitrogen (NOx) and negligible particulate matter (PM) during idle. However, carbon monoxide (CO) and hydrocarbons (HCs) from these four trucks were approximately 285 and 153 g/hr on average, respectively. The gasoline trucks consumed substantially more fuel at an hourly rate (0.84 gal/hr) than their diesel counterparts (0.44 gal/hr) during idling. The diesel trucks, on the other hand, emitted higher NOx (79 g/hr) and comparatively higher PM (4.1 g/hr), on average, than the gasoline trucks (3.8 g/hr of NOx and 0.9 g/hr of PM, on average). Idle NOx emissions from diesel trucks were high for post-1992 model year engines, but no trends were observed for fuel consumption. Idle emissions and fuel consumption from the medium heavy-duty diesel trucks (MHDDTs) were marginally lower than those from the heavy heavy-duty diesel trucks (HHDDTs), previously reported in the literature.

Energy Optimal Trajectories in Human Arm Motion Aiming for Assistive Robots

Directory of Open Access Journals (Sweden)

Lelai Zhou

2017-01-01

Full Text Available The energy expenditure in human arm has been of great interests for seeking optimal human arm trajectories. This paper presents a new way for calculating metabolic energy consumption of human arm motions. The purpose is to reveal the relationship between the energy consumption and the trajectory of arm motion, and further, the acceleration and arm orientation contributions. Human arm motion in horizontal plane is investigated by virtue of Qualisys motion capture system. The motion data is post-processed by a biomechanical model to obtain the metabolic expenditure. Results on the arm motion kinematics, dynamics and metabolic energy consumption, are included.

Effect of standard cuff on blood pressure readings in patients with obese arms. How frequent are arms of a 'large circumference'?

Fonseca-Reyes, Salvador; de Alba-García, Javier García; Parra-Carrillo, José Z; Paczka-Zapata, José Antonio

2003-06-01

To measure the effect on blood pressure readings when a standard cuff is used on patients with arms of a large circumference, and to determine the frequency of arms of a large circumference. Blood pressures were taken in 120 subjects with an arm circumference greater than 33 cm. Also, the arm circumference was determined in 244 patients from a family health unit, and in 216 patients from a hypertension clinic. A mercury sphygmomanometer and two different cuff sizes were used in a random sequence; therefore, 60 patients' blood pressure were first measured with a large cuff, followed by a standard cuff; the opposite sequence was then applied for another 60 patients. With the obtained values and using a regression analysis, the difference in blood pressure overestimation was calculated. Arm circumference measurement percentages were used to determine the frequency of arms of a large circumference. Both systolic and diastolic blood pressures were significantly greater when the standard cuff was used. For every 5 cm increase in arm circumference, starting at 35 cm, a 2-5 mmHg increase in systolic blood pressure, and a 1-3 mmHg increase in diastolic blood pressure was observed. The prevalence of arms with a large circumference in the family medicine unit and hypertension clinic was 42% and 41.8%, respectively. There is an overestimation of blood pressure when a standard cuff is used in obese subjects. The high prevalence of these individuals in our environment, both in the hypertensive and normotensive population, makes it necessary to have on hand different sizes of cuffs for taking blood pressure in order to avoid incorrect decisions.

Robots testing robots: ALAN-Arm, a humanoid arm for the testing of robotic rehabilitation systems.

Robotics is increasing in popularity as a method of providing rich, personalized and cost-effective physiotherapy to individuals with some degree of upper limb paralysis, such as those who have suffered a stroke. These robotic rehabilitation systems are often high powered, and exoskeletal systems can attach to the person in a restrictive manner. Therefore, ensuring the mechanical safety of these devices before they come in contact with individuals is a priority. Additionally, rehabilitation systems may use novel sensor systems to measure current arm position. Used to capture and assess patient movements, these first need to be verified for accuracy by an external system. We present the ALAN-Arm, a humanoid robotic arm designed to be used for both accuracy benchmarking and safety testing of robotic rehabilitation systems. The system can be attached to a rehabilitation device and then replay generated or human movement trajectories, as well as autonomously play rehabilitation games or activities. Tests of the ALAN-Arm indicated it could recreate the path of a generated slow movement path with a maximum error of 14.2mm (mean = 5.8mm) and perform cyclic movements up to 0.6Hz with low gain (<1.5dB). Replaying human data trajectories showed the ability to largely preserve human movement characteristics with slightly higher path length and lower normalised jerk.

Molecular clouds in the Carina arm - the largest objects, associated regions of star formation, and the Carina arm in the Galaxy

International Nuclear Information System (INIS)

Grabelsky, D.A.; Cohen, R.S.; Bronfman, L.; Thaddeus, P.

1988-01-01

The Columbia CO survey of the southern Galactic plane is used to identify giant molecular clouds and cloud complexes in the Vela-Carina-Centaurus section of the Galaxy. Twenty-seven giant molecular clouds between l = 270 and 300 deg are catalogued and their heliocentric distances given. In addition, 16 clouds at l greater than 300 deg beyond the solar circle extend the catalog to include the very distant portion of the Carina arm. The most massive clouds in the catalog trace the Carina arm over 23 kpc in the plane of the Galaxy. The average mass of these objects is 1.4 x 10 to the 6th solar, and their average spacing along the arm is 700 pc. The composite distribution projected onto the Galactic plane of the largest molecular clouds in the Carina arm and of similarly massive clouds in the first and second quadrants strongly suggests that the Carina and Sagittarius arms form a single spiral arm about 40 kpc in length wrapping two-thirds of the way around the Galaxy. Descriptions of each cloud, including identification of associated star-forming regions, are presented in an appendix. 76 references

This is a collection of essays presented at the above-named conference held at New Port Beach, U.S., from July 24 through 28, 1989. At the utility energy storage session, it is found that the 100kW-capable Na-S battery system of the Kansai Electric Power Company, Inc., works effectively in levelling peakloads at storage efficiency of 70%. A Chino lead-acid battery system is also described. A lead-acid battery system of the BEWAG Corporation of Germany equipped with tubular electrodes is described. For application by the consuming party, system behavior relative to duty cycle control, sudden request for energy storage, power factor, and load adjustment is discussed. Use of a valve-controlled lead-acid battery is introduced, which is to be used as a stand-by system (such as an uninterruptible power supply) or for certain types of cyclic duties. At the 4th session, economic and technical models are exhibited. Computer-aided peakload prediction, battery storage system technology, economic parameters, profitability, etc., are explained for use by the consuming party in a peakload shaving battery system. The Zn/Br battery, redox-flow battery, and other advanced technologies are also presented. (NEDO)

A Unified Approach for Reporting ARM Measurement Uncertainties Technical Report

Campos, E [Argonne National Lab. (ANL), Argonne, IL (United States); Sisterson, Douglas [Argonne National Lab. (ANL), Argonne, IL (United States)

2016-12-01

The U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility is observationally based, and quantifying the uncertainty of its measurements is critically important. With over 300 widely differing instruments providing over 2,500 datastreams, concise expression of measurement uncertainty is quite challenging. The ARM Facility currently provides data and supporting metadata (information about the data or data quality) to its users through a number of sources. Because the continued success of the ARM Facility depends on the known quality of its measurements, the Facility relies on instrument mentors and the ARM Data Quality Office (DQO) to ensure, assess, and report measurement quality. Therefore, an easily accessible, well-articulated estimate of ARM measurement uncertainty is needed. Note that some of the instrument observations require mathematical algorithms (retrievals) to convert a measured engineering variable into a useful geophysical measurement. While those types of retrieval measurements are identified, this study does not address particular methods for retrieval uncertainty. As well, the ARM Facility also provides engineered data products, or value-added products (VAPs), based on multiple instrument measurements. This study does not include uncertainty estimates for those data products. We propose here that a total measurement uncertainty should be calculated as a function of the instrument uncertainty (calibration factors), the field uncertainty (environmental factors), and the retrieval uncertainty (algorithm factors). The study will not expand on methods for computing these uncertainties. Instead, it will focus on the practical identification, characterization, and inventory of the measurement uncertainties already available in the ARM community through the ARM instrument mentors and their ARM instrument handbooks. As a result, this study will address the first steps towards reporting ARM measurement uncertainty

Breach of duty: Power of shareholders to ratify directors fraudulent dealings

Full Text Available Company directors owe duty of loyalty to the company which prohibits them from fraudulent dealings in the course of conducting the affairs of the company. Although the shareholders could, in the exercise of their voting powers, grant relieves to the directors from liabilities arising from a breach of duty that amounts to fraud, the extent and capacity in which the shareholders could exercise such powers is confounded by the elusive attempts by the courts in defining fraud. The paper argues that without a definite meaning ascribed to fraud, the power and capacity in which the shareholders could ratify a breach of duty arising from self-dealing and expropriation of corporate opportunities by directors cannot be predetermined, but that each case would be based on the peculiarities of its own facts.

Full Text Available Nowadays there exist several frameworks to utilize a computation power of graphics cards and other computational devices such as FPGA, ARM and multi-core processors. The best known are either low-level and need a lot of controlling code or are bounded only to special graphic cards. Furthermore there exist more specialized frameworks, mainly aimed to the mathematic field. Described framework is adjusted to use in a multi-agent simulations. Here it provides an option to accelerate computations when preparing simulation and mainly to accelerate a computation of simulation itself.

Reports on a United Nations committee recommendation that the Security Council establish a universal register of arms. Suggests that such a register would limit the destabilizing influence of major arms sales on developing nations. Argues that visibility of arms sales may help reduce their number. (DK)
