A new VME based high voltage power supply has been developed for the D OE experiment at Fermilab. There are three types of supplies delivering up to ±5.6 kV at 1.0 mA or +2.0 kV at 3.0 mA with a set accuracy of 1.5 V and extremely low voltage ripples. Complete computer control has allowed many special features to be developed for the supply, including user-defined control land monitor groups, variable ramp rates, and advanced histogram and graphic functions. 3 refs

EPRtm project experience: selection of partners and supply chain

International Nuclear Information System (INIS)

Lorenzo, D. de

2012-01-01

With 4 EPR T M units under construction, the new plants to be built in the following years will benefit from the return on experience of the work already performed. The knowledge about licensing processes, detail engineering, supply chain, logistics and on-site work gathered from the Olkiluoto 3 and Flamanville 3 projects has already been used in the Taishan 1 and 2 project, resulting in a project that is on schedule and on budget. This article will show how the advantage of such broad experience gained will be used to benefit future projects to ensure certainty of completion, leaving few and limited unresolved issues even before the beginning of the project. Several areas that are not usually tackled when speaking of a New Build project will be covered by this text from the point of view of a nuclear vendor: Project Partnership Selection and the Gate Review Process applied by AREVA in the supply chain of the main components.

The Electronics system of experiments for the study of rare decays, such as the neutrino-less double beta decay, must be very stable over very long expected runs. We introduce our solution for the power supply of such an experiment, CUORE. In this case the power supply chain consists of a series of ACDCs, followed by DCDCs and then Linear Regulators. We emphasize here our approach to the DCDC regulation system that was designed with a complete rejection of the switching noise, across 100 MHz bandwidth. In the experimental layout the DCDC will be located far from the very front-end, with long connecting cables (10 m). We introduced our very simple and safe solution to prevent huge over-voltages, due to the energy stored in the inductance of the cables, generated after the release of accidental short circuits, so avoiding destructive effects. Some micro-controllers are present on every board and take care of the DCDC operation. These micro-controllers are managed from the control room, via CAN BUS protocol coupled via optical fibres. CUORE is an array of 1000 cryogenic detectors that will need 30 of our DCDCs.

Murchland, Sonya; Parkyn, Helen

2010-01-01

This study explored the experience of children with physical disabilities using assistive technology for participation with schoolwork to gain a greater understanding of their perspectives and subjective experiences. A qualitative study involving thematic analysis of in-depth interviews of the child with a parent or significant adult. Purposeful sampling from a larger study recruited five children aged between 10 and 14 years, with differing physical disabilities who attended mainstream schools. All children used computer-based assistive technology. All of the children recognised that assistive technology enabled them to participate and reduced the impact of their physical disability, allowing independent participation, and facilitated higher learning outcomes. Issues related to ease of use, social implications and assistive technology systems are discussed.

Assisted-living elderly and the mealtime experience.

Although there is increasing evidence of barriers to nutritional health among elderly assisted-living residents, there has not been the same emphasis when examining the ways in which these individuals experience their mealtimes, as well as the factors that they perceive as contributing to their overall sense of health and well-being. Mealtimes may be disregarded as being particularly unimportant or hurried and overlooked, especially for those residents who may be lonely and have feelings of isolation, ultimately leading to a reduced food intake and poor nutrition. A convenience sample of 38 men and women, aged ≥65 years, were selected from four assisted-living facilities in and around Montclair, NJ, USA, to participate in focus group discussions. Data were analysed using content analysis procedures. Participants described their experiences of mealtimes, and the factors contributing to an overall sense of well-being during these occasions. The ability to make healthy food choices, socialise, interact with staff, friends and family members, and enjoy a tasty meal in a warm and inviting dining environment, may provide a dignity that is unmatched by other services. The findings of the present study highlight the importance of maintaining the health of elderly assisted-living residents through strategies that enhance their mealtime experiences. Listening to the food voice of elderly through research such as that carried out in the present study will help policy makers develop a plan that will effectively deal with systemic barriers prevalent in these facilities, and incorporate strategies to motivate and encourage their residents to increase their food intake and improve their health and well-being. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Analysis of Supply and Demand to Enhance Educational Tourism Experience in the Smart Park of Yogyakarta, Indonesia

Directory of Open Access Journals (Sweden)

Ani Wijayanti

2017-11-01

Full Text Available The Smart Park (also known as Taman Pintar is a major educational tourist destination in Yogyakarta, which offers a variety of attractions that are very interesting for tourists. The main purpose of tourists visiting Smart Park is to obtain an educational tourism experience. This subjective experience raises specific challenges for Smart Park as it works towards being a competitive destination. The purpose of this study is to analyze the aspects of the educational tourism experience that are affected by tourism demand and supply. Data were collected from surveys that were sent to 150 respondents and were analyzed using path analysis. The results show that tourism demand and supply contributed to the variation of tourism activities by 45.1%, while the remaining was explained by other variables, such as national budget, local budget, ticket sale, and cooperation with some stakeholders. Tourism supply had a higher effect than tourism demand. Tourism demand did not particularly affect tourism experience. However, the results of the path analysis indicate that tourism supply had direct and indirect effects on tourism experience through the variation of tourism activities, with the indirect effect being the most predominant. In the management of Smart Park, there is still a gap between tourism demand and supply, so the tourism experience has not been maximized to its full potential.

The RHIC Beam Abort Kicker Power Supply Systems commissioning experience and the remaining issues will be reported in this paper. The RHIC Blue Ring Beam Abort Kicker Power Supply System initial commissioning took place in June 1999. Its identical system in Yellow Ring was brought on line during Spring 2000. Each of the RHIC Beam Abort Kicker Power Supply Systems consists of five high voltage modulators and subsystems. These systems are critical devices for RHIC machine protection and environmental protection. They are required to be effective, reliable and operating with sufficient redundancy to safely abort the beam to its beam dump at the end of accumulation or at any time when they are commanded. To deflect 66 GeV ion beam to the beam absorbers, the RHIC Beam Abort Kicker Power Supply Systems were operated at 22 kV level. The RHIC 2000 commissioning run was very successful

2014-09-01

Da Vinci robot-assisted thymectomy has been used in the past several years in China, however, practical experience in performing this approach in China remains limited. Thus, the study aimed to evaluate the experience of da Vinci robot-assisted thymectomy in China. From June 2010 to December 2012, 55 patients with diseases of the thymus underwent thymectomy using the da Vinci surgical HD robotic system. The clinical data of the da Vinci robot-assisted thymectomies were compared with the data of video-assisted thoracoscopic thymectomies in the same period. All da Vinci robot operations were successful. This is a retrospective analysis which demonstrated that compared with video-assisted thoracoscopic thymectomy in the same period, the clinical outcomes of da Vinci robot-assisted thymectomy were not significantly different. The da Vinci robot-assisted thymectomy is a safe, minimally invasive, and convenient operation, and shows promise for general thoracic surgery in China. Copyright © 2014 John Wiley & Sons, Ltd.

An approach for high voltage power supply system for HCAL of LHCb experiment

The main aim of the calorimeter system of the LHCb (Large Hadron Collider Beauty) experiment dedicated to precision measurements of CP violation and rare phenomena is to provide identification of the electrons, hadrons and photons, for the level-0 trigger and offline analysis with measurements of position and energy. The system consists in a scintillator pad/preshower (SPD/PS) detector, an electromagnetic calorimeter (ECAL) and a hadron calorimeter (HCAL), all the sub-detectors having a similar technology with scintillating tiles as active material and being read out via wavelength-shifting fibers and with an identical readout electronics for ECAL and HCAL and similar electronics for the PS. During 1997-1999 a computer controlled High Voltage (HV) distribution scheme was developed by Horia Hulubei National Institute for Physics and Nuclear Engineering (IFIN-HH) group and used to supply the PMTs of half HCAL prototype during the beam tests (1998-2000). This scheme consisted of three parts: 1) a control box which includes low voltage power supply, the RS232 interface to a PC and three modules of high voltage power supply; 2) two types of multichannel HV distributors with an individual voltage setting; 3) a software package to control all settings and refresh them periodically. Based on the acquired experience, a new design for a High Voltage Power Supply (HVPS) which satisfies the LHCb requirements has been developed for PMTs of the hadron calorimeter. The demands of this system are simplicity and low cost. This HVPS with multiple outputs (HV for photocathode and D1 - D4 dynodes) is destined to supply, with the same high voltage, groups of PMTs sorted by similar characteristics as gain and sensitivity. Because of the high rates (∼ 40 MHz) supported by PMTs, booster voltage sources are necessary to supply current for the last 4 dynodes. The box has 5 HV power supplies for photocathodes and the last 4 dynodes, each HV power supply being followed by a 4 channel

To continuously supply remote villages and settlements not connected to the public grid with electric power is an ambitious technical task considering ecological and economical points of view. The German company SMA has developed a modular supply system as a solution for this task in the range of 30 kW to 5 MW. Meanwhile more than 20 applications of these 'Intelligent Power Systems (IPS)' have proved their technical reliability and economical competitiveness worldwide under different, and also extreme environmental conditions. Actually it is the first commercially available advanced Wind/Diesel/Battery System for remote area electrification. The modular autonomous electric supply systems realized by SMA basically consist of two or more diesel power sets, battery storage with converter, a rotating phaseshifter, and an optional number of wind turbines. All modules are coupled on the 3-phase AC system grid and run in various parallel configurations depending on the wind speed and the consumer power demand. The control system operates fully automatical and offers a very user-friendly graphical interface. This advanced system control also contains a remote control and operating data output via modem and telephone line. SMA and CES have considerable experience with Wind/Diesel/Battery Systems for more than eight years. In many cases wind energy converters in the power range of 30 to 40 kW were used, but it is also possible to use larger wind turbines (e.g. 250 kW). In the following the system technology is described in detail, experience of different system sizes in several countries of application is presented, and economical analyses for power supply by IPS are given in comparison to a conventional fully diesel power supply.

2016-01-01

Laparoscopic sleeve gastrectomy has become a stand-alone procedure in the treatment of morbid obesity. There are very few reports on the use of robotic approach in sleeve gastrectomy. The purpose of this retrospective study is to report our early experience of robotic-assisted laparoscopic sleeve gastrectomy (RALSG) using a proctored training model with comparison to an institutional cohort of patients who underwent laparoscopic hand-assisted sleeve gastrectomy (LASG). University hospital. The study included 108 patients who underwent sleeve gastrectomy either via the laparoscopic-assisted or robot-assisted approach during the study period. Of these 108 patients, 62 underwent LASG and 46 underwent RALSG. The console surgeon in the RALSG is a clinical year 4 (CY4) surgery resident. All CY4 surgery residents received targeted simulation training before their rotation. The console surgeon is proctored by the primary surgeon with assistance as needed by the second surgeon. The patients in the robotic and laparoscopic cohorts did not have a statistical difference in their demographic characteristics, preoperative co-morbidities, or complications. The mean operating time did not differ significantly between the 2 cohorts (121 min versus 110 min, P = .07). Patient follow-up in the LSG and RALSG were 91% and 90% at 3 months, 62% and 64% at 6 months, and 60% and 55% at 1 year, respectively. The mean percentage estimated weight loss (EWL%) at 3 months, 6 months, and 1 year was greater in the robotic group but not statistically significant (27 versus 22 at 3 mo [P = .05] and 39 versus 34 at 6 mo [P = .025], 57 versus 48 at 1 yr [P = .09]). There was no mortality in either group. Early results of our experience with RALSG indicate low perioperative complication rates and comparable weight loss with LASG. The concept of a stepwise education model needs further validation with larger studies. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc

Demonstration of entanglement assisted invariance on IBM's quantum experience.

Science.gov (United States)

Deffner, Sebastian

2017-11-01

Quantum entanglement is among the most fundamental, yet from classical intuition also most surprising properties of the fully quantum nature of physical reality. We report several experiments performed on IBM's Quantum Experience demonstrating envariance - entanglement assisted invariance. Envariance is a recently discovered symmetry of composite quantum systems, which is at the foundational origin of physics and a quantum phenomenon of pure states. These very easily reproducible and freely accessible experiments on Quantum Experience provide simple tools to study the properties of envariance, and we illustrate this for several cases with "quantum universes" consisting of up to five qubits.

2009-01-01

There has been a growing concern in higher education about our failure to produce scientifically trained workers and scientifically literate citizens. Active-learning and research-oriented activities are posited as ways to give students a deeper understanding of science. We report on an undergraduate teaching assistant (UTA) experience and suggest that students who participate as a UTA obtain benefits analogous to those who participate as an undergraduate research assistant (URA). We examined the experiences of 24 undergraduates acting as UTAs in a general microbiology course. Self-reported gains by the UTAs were supported by observational data from undergraduates in the course who were mentored by the UTAs and by the graduate teaching assistants (GTAs) with whom the UTAs worked. Specifically, data from the UTAs’ journals and self-reported Likert scales and rubrics indicated that our teaching assistants developed professional characteristics such as self-confidence and communication and leadership skills, while they acquired knowledge of microbiology content and laboratory skills. Data from the undergraduate Likert scale as well as the pre- and post-GTA rubrics further confirmed our UTA’s data interpretations. These findings are significant because they offer empirical data to support the suggestion that the UTA experience is an effective option for developing skills and knowledge in undergraduates that are essential for careers in science. The UTA experience provides a valuable alternative to the URA experience. PMID:23653688

International experiences with power supply crises

International Nuclear Information System (INIS)

2002-01-01

Many so-called deregulated power markets experience a hardened energy and power balance and some have had supply crises. This report discusses the crises, their impacts and their causes as well as the measures taken by the authorities to solve the crises. It also considers the similarities or dissimilarities with respect to the situation in Norway the winter 2002/2003. Like Norway, many of the countries have a considerable share of hydroelectric power. It is found, however, that the dependence on water of its own is not the reason for the crises, but that the inflow conditions give the market greater challenges. Furthermore, the Norwegian market has greater flexibility in the consumption, greater import capacity, better price security possibilities and less problems with market power than most of the countries here considered. Various factors influence a country's power consumption and production capacity. Economic growth and the availability of inexpensive power contribute to accelerate the consumption, while predictable external conditions and sufficient expected investment earnings are necessary to achieve an increase of the capacity - both through new investments and attendance to existing capacity. In a smooth power market there must be a certain correspondence between consumption and installed capacity, and the capacity must be such that it can cover the continuous demand for power and at the same time be flexible enough to deliver power at peak loads. This is also true of the transmission capacity. In addition, some extra capacity must be available for unexpected events. The basic problem is, in any power market, that the consumption may rise fast, while the investments in new capacity typically occurs in leaps, with long and costly construction phases. Many countries have lately experienced a hardening of the balance between consumption and capacity and so have been vulnerable to unexpected increases in consumption or resource failure. This was also the

Laparoscopic hand-assisted pancreaticoduodenectomy: initial UK experience.

Science.gov (United States)

Ammori, B J

2004-04-01

By and large, the limited world experience with laparoscopic pancreaticoduodenectomy (PD) has been unfavorable, but the laparoscopic hand-assisted approach to PD has recently shown promising results. We report the first successful UK experience with laparoscopic hand-assisted PD (LHAPD). A 62-year-old man who presented with painless obstructive jaundice was found at endoscopy, to have an ampullary tumor. Preoperative biopsy specimens confirmed the diagnosis of an adenocarcinoma, and CT showed no evidence of either vascular involvement or metastatic disease. A staging laparoscopy showed no intraabdominal metastases, and an LHAPD was performed using a Gelport. The intraoperative course was uneventful. Two units of blood were transfused intraoperatively, but no postoperative blood transfusion was required. The operative time was 11 h (plus a 30-min break). The patients postoperative recovery was uneventful except for superficial pressure sores over the buttocks and elbows. The patient resumed oral fluid and dietary intake on the 1st and 3rd postoperative days, respectively, and was discharged from hospital on the 9th postoperative day. Histology demonstrated an ampullary adenocarcinoma with clear resection margins and involvement of two of the 13 lymph nodes examined. At 2-month follow-up, the patient remains well and is receiving adjuvant chemotherapy. LHAPD achieves good oncological clearance and can be performed safely in selected patients. The early promising results with this approach will undoubtedly encourage wider adoption of this procedure and are likely to widen the selection criteria.

Abstract Realistic planning for a nutrition intervention is a critical component of implementation, yet effective approaches have been poorly documented. Under the auspices of “The Micronutrient Powders Consultation: Lessons Learned for Operational Guidance,” 3 working groups were formed to summarize experiences and lessons across countries regarding micronutrient powders (MNP) interventions for young children. This paper focuses on programmatic experiences in the planning stages of an MNP intervention, encompassing assessment, enabling environment and adaptation, as well as considerations for supply. Methods included a review of published and grey literature, key informant interviews, and deliberations throughout the consultation process. We found that assessments helped justify adopting an MNP intervention, but these assessments were often limited by their narrow scope and inadequate data. Establishing coordinating bodies and integrating MNP into existing policies and programmes have helped foster an enabling environment and support programme stability. Formative research and pilots have been used to adapt MNP interventions to specific contexts, but they have been insufficient to inform scale‐up. In terms of supply, most countries have opted to procure MNP through international suppliers, but this still requires understanding and navigating the local regulatory environment at the earliest stages of an intervention. Overall, these findings indicate that although some key planning and supply activities are generally undertaken, improvements are needed to plan for effective scale‐up. Much still needs to be learned on MNP planning, and we propose a set of research questions that require further investigation. PMID:28960875

Family Caregivers' Reflections on Experiences of Assisted Suicide in Switzerland: A Qualitative Interview Study.

Gamondi, C; Pott, Murielle; Preston, Nancy; Payne, Sheila

2018-04-01

Thousands of family members worldwide are annually involved in assisted dying. Family participation in assisted dying has rarely been investigated and families' needs typically are not considered in assisted dying legislation and clinical guidelines. To explore family caregivers' reflections on experiences of assisted suicide in Switzerland. A cross-sectional qualitative interview study conducted in the Italian- and French-speaking regions of Switzerland. Interpretation and analysis were performed using qualitative content analysis. Twenty-eight close relatives and family carers of 18 patients who died by assisted suicide in Switzerland were interviewed. Family members perceived their involvement in assisted suicide as characterized by five phases; 1) contemplation, 2) gaining acceptance, 3) gaining permission, 4) organization, and 5) aftermath. Families can participate in these phases at diverse levels and with varying degrees of involvement. Important triggers for families and patients for transition between phases include patients' experiences of their life-threatening illnesses and related treatments, their increasing awareness of approaching death, and family member recognition of their loved one's unbearable suffering. Participating in assisted suicide created further demanding tasks for families in addition to their role of caregivers. Families appeared to be involved in the preparation of assisted suicide along with patients, irrespective of their personal values regarding assisted dying. Support for family members is essential if they are involved in tasks preparatory to assisted suicide. Clinical guidelines and policies concerning assisted dying should acknowledge and address family needs. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

Hope and despair: community health assistants' experiences of working in a rural district in Zambia.

Science.gov (United States)

Zulu, Joseph Mumba; Kinsman, John; Michelo, Charles; Hurtig, Anna-Karin

2014-05-25

In order to address the challenges facing the community-based health workforce in Zambia, the Ministry of Health implemented the national community health assistant strategy in 2010. The strategy aims to address the challenges by creating a new group of workers called community health assistants (CHAs) and integrating them into the health system. The first group started working in August 2012. The objective of this paper is to document their motivation to become a CHA, their experiences of working in a rural district, and how these experiences affected their motivation to work. A phenomenological approach was used to examine CHAs' experiences. Data collected through in-depth interviews with 12 CHAs in Kapiri Mposhi district and observations were analysed using a thematic analysis approach. Personal characteristics such as previous experience and knowledge, passion to serve the community and a desire to improve skills motivated people to become CHAs. Health systems characteristics such as an inclusive work culture in some health posts motivated CHAs to work. Conversely, a non-inclusive work culture created a social structure which constrained CHAs' ability to learn, to be innovative and to effectively conduct their duties. Further, limited supervision, misconceptions about CHA roles, poor prioritisation of CHA tasks by some supervisors, as well as non- and irregular payment of incentives also adversely affected CHAs' ability to work effectively. In addition, negative feedback from some colleagues at the health posts affected CHA's self-confidence and professional outlook. In the community, respect and support provided to CHAs by community members instilled a sense of recognition, appreciation and belonging in CHAs which inspired them to work. On the other hand, limited drug supplies and support from other community-based health workers due to their exclusion from the government payroll inhibited CHAs' ability to deliver services.

Experience using individually supplied heater rods in critical power testing of advanced BWR fuel

Energy Technology Data Exchange (ETDEWEB)

Majed, M.; Morback, G.; Wiman, P. [ABB Atom AB, Vasteras (Sweden)] [and others

1995-09-01

The ABB Atom FRIGG loop located in Vasteras Sweden has during the last six years given a large experience of critical power measurements for BWR fuel designs using indirectly heated rods with individual power supply. The loop was built in the sixties and designed for maximum 100 bar pressure. Testing up to the mid eighties was performed with directly heated rods using a 9 MW, 80 kA power supply. Providing test data to develop critical power correlations for BWR fuel assemblies requires testing with many radial power distributions over the full range of hydraulic conditions. Indirectly heated rods give large advantages for the testing procedure, particularly convenient for variation of individual rod power. A test method being used at Stern Laboratories (formerly Westinghouse Canada) since the early sixties, allows one fuel assembly to simulate all required radial power distributions. This technique requires reliable indirectly heated rods with independently controlled power supplies and uses insulated electric fuel rod simulators with built-in instrumentation. The FRIGG loop was adapted to this system in 1987. A 4MW power supply with 10 individual units was then installed, and has since been used for testing 24 and 25 rod bundles simulating one subbundle of SVEA-96/100 type fuel assemblies. The experience with the system is very good, as being presented, and it is selected also for a planned upgrading of the facility to 15 MW.

What are the experiences of trans persons (i.e. those whose gender identity does not match the gender assigned to them at birth) who sought or accessed assisted reproduction (AR) services in Ontario, Canada, between 2007 and 2010? The majority of trans persons report negative experiences with AR service providers. Apart from research examining desire to have children among trans people, most of the literature on this topic has debated the ethics of assisting trans persons to become parents. To-date, all of the published research concerning trans persons' experiences with AR services is solely from the perspective of service providers; no studies have examined the experiences of trans people themselves. Secondary qualitative research study of data from nine trans-identified people and their partners (total n = 11) collected as part of a community-based study of access to AR services for sexual and gender minority people between 2010 and 2012. Trans-identified volunteers (and their partners, when applicable) who had used or attempted to access AR services since 2007 from across Ontario, Canada, participated in a 60-90 minute, semi-structured qualitative interview. Qualitative analysis was performed using a descriptive phenomenological approach. Emerging themes were continually checked against the data as part of an iterative process. The data highlight barriers to accessing AR services for trans people. Participant recommendations for improving AR service provision to better meet the needs of this population are presented. These recommendations address the following areas: (i) AR service provider education and training; (ii) service provider and clinic practices and (iii) clinic environment. The majority of study participants were trans people who identified as men and who resided in major urban areas; those living in smaller communities may have different experiences that were not adequately captured in this analysis.

Full Text Available The decision to undergo medically assisted reproduction techniques involves a series of ethical questions that men and women of all times have had to answer: why do so? Wwho decides? Why so? Why not? How to face the process? We look at History to help them respond from the experience of so many women and couples who have needed to react toattend their impossible reproduction with the most unlikely resources. Looking at the subject and theirhis experience of meaning may be a more fruitful bioethical proposal than resorting toducing reflecting solely onion only to techniques.

To describe our experience in the first cases of urological surgeries performed with the da Vinci single-port robot-assisted platform. We performed 5 single-port robot-assisted surgeries (R-LESS) between May and October 2014. We performed 3 ureteral reimplant surgeries, one ureteropyeloplasty in an inverted kidney and 1 partial nephrectomy. The perioperative and postoperative results were collected, as well as a report of the complications according to the Clavien classification system. Of the 5 procedures, 4 were performed completely by LESS, while 1 procedure was reconverted to multiport robot-assisted surgery. There were no intraoperative complications. We observed perioperative complications in 4 patients, all of which were grade 1 or 2. The mean surgical time was 262minutes (range, 230-300). In our initial experience with the da Vinci device, R-LESS surgery was feasible and safe. There are still a number of limitations in its use, which require new and improved R-LESS platforms.

Computed tomography (CT)-compatible robots, both commercial and research-based, have been developed with the intention of increasing the accuracy of needle placement and potentially improving the outcomes of therapies in addition to reducing clinical staff and patient exposure to radiation during CT fluoroscopy. In the case of highly inaccessible lesions that require multiple plane angulations, robotically assisted needles may improve biopsy access and targeted drug delivery therapy by avoidance of the straight line path of normal linear needles. We report our preliminary experience of performing radiofrequency ablation of the liver using a robotic-assisted CT guidance system on 11 patients (17 lesions). Robotic-assisted planning and needle placement appears to have high accuracy, is technically easier than the non-robotic-assisted procedure, and involves a significantly lower radiation dose to both patient and support staff.

This study investigates removal of cephalexin using ozonation in the presence of granular activated carbon. Initial experiments were carried out about adsorption of cephalexin onto granular activated carbon, effect of catalytic ozonation, and biodegradability of cephalexin solution. The effect of ozonation on pH, ozone utilization efficiency and decomposition byproducts, was observed. Response surface methodology was adopted to optimize three operating parameters pH of solution, ozone supply and cephalexin concentration. GAC assisted ozonation, was found to be effective in decomposing COD (chemical oxygen demand) and cephalexin from solution. Optimum values of variables were pH from 7-8, ozone supply 30 mg/L and 100 mg/L of cephalexin solution. The complete removal of cephalexin and 60% COD removal was achieved at these optimum input values. (author)

The composite supply chain efficiency model: A case study of the Sishen-Saldanha supply chain

Directory of Open Access Journals (Sweden)

Leila L. Goedhals-Gerber

2016-01-01

Full Text Available As South Africa strives to be a major force in global markets, it is essential that South African supply chains achieve and maintain a competitive advantage. One approach to achieving this is to ensure that South African supply chains maximise their levels of efficiency. Consequently, the efficiency levels of South Africa’s supply chains must be evaluated. The objective of this article is to propose a model that can assist South African industries in becoming internationally competitive by providing them with a tool for evaluating their levels of efficiency both as individual firms and as a component in an overall supply chain. The Composite Supply Chain Efficiency Model (CSCEM was developed to measure supply chain efficiency across supply chains using variables identified as problem areas experienced by South African supply chains. The CSCEM is tested in this article using the Sishen-Saldanda iron ore supply chain as a case study. The results indicate that all three links or nodes along the Sishen-Saldanha iron ore supply chain performed well. The average efficiency of the rail leg was 97.34%, while the average efficiency of the mine and the port were 97% and 95.44%, respectively. The results also show that the CSCEM can be used by South African firms to measure their levels of supply chain efficiency. This article concludes with the benefits of the CSCEM.

Experiment of Power Supply Method for WLAN Sensor Using Both Energy Harvesting and Microwave Power Transmission

International Nuclear Information System (INIS)

Sakaguchi, K; Yamashita, S; Yamamoto, K; Nishio, T; Morikura, M; Huang, Y; Shinohara, N

2014-01-01

This paper proposes to improve effectiveness of supplying a sensor with energy using microwave power transmission (MPT) and energy harvesting (EH). The MPT duration should be as short as possible to avoid serious interference between the MPT and wireless local area network data transmission when co-channel operation of both microwave power transmission (MPT) and wireless data transmissions is performed. To shorten the MPT duration, we use multiple power sources such as an MPT source and an EH source to supply a sensor with power. Here, an overcharge or an energy shortage could occur at the sensor if the power supplied by both the MPT and EH sources is not adjusted appropriately. To solve this problem, the power supplied by multiple sources should be estimated precisely. In this paper, we propose a scheme for estimating the power supplied by multiple sources on the basis of an existing MPT scheduling system and then conducted an experiment using the scheme. From the experimental results, it is confirmed to estimate the power supplied by multiple sources successfully. In addition, the required MPT duration when the EH source is used is reduced compared to that when it is not used. Moreover, it is confirmed that the sensor station successfully estimates the power supplied by an MPT source and that by an EH source and adequately configures the MPT duration

Robot-assisted pancreatoduodenectomy with preservation of the vascular supply for autologous islet cell isolation and transplantation: a case report

Directory of Open Access Journals (Sweden)

Giulianotti Piero

2012-03-01

Full Text Available Abstract Introduction For patients with chronic pancreatitis presenting with medically intractable abdominal pain, surgical intervention may be the only treatment option. However, extensive pancreatic resections are typically performed open and are associated with a substantial amount of postoperative pain, wound complications and long recovery time. Minimally invasive surgery offers an avenue to improve results; however, current limitations of laparoscopic surgery render its application in the setting of chronic pancreatitis technically demanding. Additionally, pancreatic resections are associated with a high incidence of diabetes. Transplantation of islets isolated from the resected pancreas portion offers a way to prevent post-surgical diabetes; however, preservation of the vascular supply during pancreatic resection, which determines islet cell viability, is technically difficult using current laparoscopic approaches. With recent advances in the surgical field, robotic surgery now provides a means to overcome these obstacles to achieve the end goals of pain relief and preserved endocrine function. We present the first report of a novel, minimally invasive robotic approach for resection of the pancreatic head that preserves vascular supply and enables the isolation of a high yield of viable islets for transplantation. Case presentation A 35-year old Caucasian woman presented with intractable chronic abdominal pain secondary to chronic pancreatitis, with a stricture of her main pancreatic duct at the level of the ampulla of Vater and distal dilatation. She was offered a robotic-assisted pylorus-preserving pancreatoduodenectomy and subsequent islet transplantation, to both provide pain relief and preserve insulin-secretory reserves. Conclusion We present a novel, minimally invasive robotic approach for resection of the pancreatic head with complete preservation of the vascular supply, minimal warm ischemia time (less than three minutes and

The Supply of Medical Radioisotopes. An Economic Study of the Molybdenum-99 Supply Chain

International Nuclear Information System (INIS)

2010-01-01

The reliable supply of molybdenum-99 (Mo-99) and its decay product, technetium-99m (Tc-99m), is a vital component of modern medical diagnostic practices. Disruptions in the supply chain of these radioisotopes - which cannot be effectively stored - can suspend important medical testing services. Unfortunately, supply reliability has declined over the past decade, due to unexpected or extended shutdowns at the few ageing, Mo-99 producing, research reactors and processing facilities. These shutdowns have created global supply shortages. The full study offers a unique analysis of the economic structure and present state of the Mo-99/Tc-99m supply chain. It finds that the shortages are a symptom of a longer-term problem linked to insufficient capital investment, which has been brought about by an economic structure that does not provide sufficient remuneration for producing Mo-99 or support for developing additional production and processing infrastructure. To assist governments and other decision makers in their efforts to ensure long-term, reliable supply of these important medical isotopes, the study presents options for creating a sustainable economic structure. The study will also enhance understanding amongst stakeholders of the costs of supplying Mo-99 and ultimately contribute to a better functioning market. (authors)

Older individuals' experiences during the assistive technology device service delivery process.

Gramstad, Astrid; Storli, Sissel Lisa; Hamran, Torunn

2014-07-01

Providing assistive technology devices to older individuals living in their ordinary homes is an important intervention to increase and sustain independence and to enable ageing at home. However, little is known about older individuals' experiences and needs in the assistive technology device (ATD) service delivery process. The purpose of this study was to investigate older individuals' experiences during the service delivery process of ATDs. Nine older individuals were interviewed three times each throughout the ATD service delivery process. The interviews were analysed within a hermeneutical phenomenological perspective. The results show that the service delivery process could be interpreted as an enigmatic journey and described using four themes: "hope and optimistic expectations", "managing after delivery or needing additional help", "having available help versus being abandoned", and "taking charge or putting up". The results emphasize the need for occupational therapists to maintain an individualized approach towards older clients throughout the service delivery process. The experiences of older individuals were diverse and related to expectations that were not necessarily articulated to the occupational therapist. The situation when the ATD is delivered to the client was highlighted by the clients as an important event with the potential to facilitate a successful service delivery process.

Tamayo-Velázquez, María-Isabel; Simón-Lorda, Pablo; Cruz-Piqueras, Maite

2012-09-01

The aim of this study is to assess the knowledge, attitudes and experiences of Spanish nurses in relation to euthanasia and physician-assisted suicide. In an online questionnaire completed by 390 nurses from Andalusia, 59.1% adequately identified a euthanasia situation and 64.1% a situation involving physician-assisted suicide. Around 69% were aware that both practices were illegal in Spain, while 21.4% had received requests for euthanasia and a further 7.8% for assisted suicide. A total of 22.6% believed that cases of euthanasia had occurred in Spain and 11.4% believed the same for assisted suicide. There was greater support (70%) for legalisation of euthanasia than for assisted suicide (65%), combined with a greater predisposition towards carrying out euthanasia (54%), if it were to be legalised, than participating in assisted suicide (47.3%). Nurses in Andalusia should be offered more education about issues pertaining to the end of life, and extensive research into this area should be undertaken.

Tyagi, R.K.; Tripathi, A.; Upadhyay, R.; Badapanda, M.K.; Lad, M.

2015-01-01

An AC regulator based -20 kV, 5 A DC power supply is employed to bias 60 kW, 505.8 MHz klystron amplifier in Indus-2 RF system. A three terminal triggered spark gap based crowbar along with suitable limiting elements is incorporated at the output of the power supply for protection of sensitive klystron amplifier during load arcing conditions. Wire burn test is carried out on this power supply along with crowbar to ensure that the stored energy dumped into klystron during its arcing is less than 20 Joule. Various protection circuits like over voltage, over current, under voltage, phase failure, thermal overload and transformer oil over temperature protection have been incorporated in this power supply. Preventive maintenance of the power supply is carried out at regular intervals to ensure that it operates satisfactorily during actual operation.This includes checking the breakdown strength of transformer oil, drying of Silica gels in transformer breathers, checking of all electrical connections and cleaning of all high voltage components. The calibration of various meters, checking the setting of various protection-interlock cards and checking the healthiness of crowbar system are also done at regular intervals. During operation, crucial performance parameters of this power supply along with various interlock signals are continuously monitored. Suitable arrangement has been made to operate this supply either in local mode as well as in remote mode. This power supply is operating satisfactorily with klystron amplifier in Indus-2 RF system in round the clock mode for last 15 years and its operational experience are presented in this paper.

Kulig, Judith C; Penz, Kelly; Karunanayake, Chandima; MacLeod, Martha L P; Jahner, Sharleen; Andrews, Mary Ellen

2017-05-01

Globally, disasters are on the rise. Nurses play a significant role in responding to such events but little is known about rural and remote nurses' experiences. A national cross-sectional survey of regulated nurses (registered nurses, registered psychiatric nurses, licensed practical nurses and nurse practitioners) in rural and remote Canada provided the data (n=2465) for the logistic regression of predictors of assisting with a disaster event within the last five years. The types of disaster events were also examined and open-ended responses were explored to reveal nurses' perspectives. Nurse type, age, region of employment, employment status, number of rural communities worked, distance to advanced referral centre, remote community, personal-professional boundaries, burnout and work engagement were significant factors related to assisting with a disaster event. Open-ended data alluded to the importance of pre-disaster preparation, and the difficulties experienced when personal-professional relationships are impacted during a disaster. Nursing education curricula needs to include information about disasters and the nurse's role. Continuing education opportunities and preparation for nurses should be offered in the workplace. Psychosocial supports to assist rural nurses who attend to disasters in their workplace will help them deal with issues such as the blurring of personal-professional relationships.

Drug supply chain safety has become a priority for public health which implies a collective process. This process associates all health professionals including the pharmacist who plays a major role. The objective of this present paper is to describe the several approaches proven effective in the reduction of drug-related problem in hospital, illustrated by the Grenoble University Hospital experience. The pharmacist gets involved first in the general strategy of hospital drug supply chain, second by his direct implication in clinical activities. The general strategy of drug supply chain combines risk management, coordination of the Pharmacy and Therapeutics Committee, selection and purchase of drugs and organisation of drug supply chain. Computer management of drug supply chain is a major evolution. Nominative drug delivering has to be a prior objective and its implementation modalities have to be defined: centralized or decentralized in wards, manual or automated. Also, new technologies allow the automation of overall drug distribution from central pharmacy and the implementation of automated drug dispensing systems into wards. The development of centralised drug preparation allows a safe compounding of high risk drugs, like cytotoxic drugs. The pharmacist should develop his clinical activities with patients and other health care professionals in order to optimise clinical decisions (medication review, drug order analysis) and patients follow-up (therapeutic monitoring, patient education, discharge consultation).

Villanueva-Sáenz, Eduardo; Ramírez-Ramírez, Moisés Marino; Zubieta-O'Farrill, Gregorio; García-Hernández, Luis

Colorectal surgery has advanced notably since the introduction of the mechanical suture and the minimally invasive approach. Robotic surgery began in order to satisfy the needs of the patient-doctor relationship, and migrated to the area of colorectal surgery. An initial report is presented on the experience of managing colorectal disease using robot-assisted surgery, as well as an analysis of the current role of this platform. A retrospective study was conducted in order to review five patients with colorectal disease operated using a robot-assisted technique over one year in the initial phase of the learning curve. Gender, age, diagnosis and surgical indication, surgery performed, surgical time, conversion, bleeding, post-operative complications, and hospital stay, were analysed and described. A literature review was performed on the role of robotic assisted surgery in colorectal disease and cancer. The study included 5 patients, 3 men and 2 women, with a mean age of 62.2 years. Two of them were low anterior resections with colorectal primary anastomoses, one of them extended with a loop protection ileostomy, a Frykman-Goldberg procedure, and two left hemicolectomies with primary anastomoses. The mean operating time was 6hours and robot-assisted 4hours 20minutes. There were no conversions and the mean hospital stay was 5 days. This technology is currently being used worldwide in different surgical centres because of its advantages that have been clinically demonstrated by various studies. We report the first colorectal surgical cases in Mexico, with promising results. There is enough evidence to support and recommend the use of this technology as a viable and safe option.

The breakdown and plasma start-up in ITER are well known issues studied in the last few years in many tokamaks with the aid of calculation based on simplified modeling. The thickness of ITER metallic wall and the voltage limits of the Central Solenoid Power Supply strongly limit the maximum toroidal electric field achievable (0.3 V/m), well below the level used in the present generation of tokamaks. In order to have a safe and robust breakdown, the use of Electron Cyclotron Power to assist plasma formation and current rump up has been foreseen. This has raised attention on plasma formation phase in presence of EC wave, especially in order to predict the required power for a robust breakdown in ITER. Few detailed theory studies have been performed up to nowadays, due to the complexity of the problems. A simplified approach, extended from that proposed in ref[1] has been developed including a impurity multispecies distribution and an EC wave propagation and absorption based on GRAY code. This integrated model (BK0D) has been benchmarked on ohmic and EC assisted experiments on FTU and AUG, finding the key aspects for a good reproduction of data. On the basis of this, the simulation has been devoted to understand the best configuration for ITER case. The dependency of impurity distribution content and neutral gas pressure limits has been considered. As results of the analysis a reasonable amount of power (1 - 2 MW) seems to be enough to extend in a significant way the breakdown and current start up capability of ITER. The work reports the FTU data reproduction and the ITER case simulations.

A Review of the Wood Pellet Value Chain, Modern Value/Supply Chain Management Approaches, and Value/Supply Chain Models

Directory of Open Access Journals (Sweden)

Natalie M. Hughes

2014-01-01

Full Text Available We reviewed 153 peer-reviewed sources to provide identification of modern supply chain management techniques and exploration of supply chain modeling, to offer decision support to managers. Ultimately, the review is intended to assist member-companies of supply chains, mainly producers, improve their current management approaches, by directing them to studies that may be suitable for direct application to their supply chains and value chains for improved efficiency and profitability. We found that information on supply chain management and modeling techniques in general is available. However, few Canadian-based published studies exist regarding a demand-driven modeling approach to value/supply chain management for wood pellet production. Only three papers were found specifically on wood pellet value chain analysis. We propose that more studies should be carried out on the value chain of wood pellet manufacturing, as well as demand-driven management and modeling approaches with improved demand forecasting methods.

Atamer, A.; Delaney, M.; Young, L. R.

2002-01-01

The expert system, Principal Investigator-in-a-box, or [PI], was designed to assist astronauts or other operators in performing experiments outside their expertise. Currently, the software helps astronauts calibrate instruments for a Sleep and Respiration Experiment without contact with the investigator on the ground. It flew on the Space Shuttle missions STS-90 and STS-95. [PI] displays electrophysiological signals in real time, alerts astronauts via the indicator lights when a poor signal quality is detected, and advises astronauts how to restore good signal quality. Thirty subjects received training on the sleep instrumentation and the [PI] interface. A beneficial effects of [PI] and training reduced troubleshooting time. [PI] benefited subjects on the most difficult scenarios, even though its lights were not 100% accurate. Further, questionnaires showed that most subjects preferred monitoring waveforms with [PI] assistance rather than monitoring waveforms alone. This study addresses problems of complex troubleshooting and the extended time between training and execution that is common to many human operator situations on earth such as in power plant operation, and marine exploration.

This paper describes recent results at Kubota to develop a gas engine driven freon-free heat supply system. Utilizing a gas mixture which consists of CO and H{sub 2} supplied from a broad area energy utilization network, the system produces four heat sources (263 K, 280 K, 318 K, and 353 K) for air-conditioning, hot water supply, and refrigeration in a single system. It also conforms to fuel systems that utilize methane and hydrogen. This multi-functional heat supply system is composed of an efficient gas engine (methanol gas engine) and a freon-free heat pump (heat-assisted Stirling heat pump). The heat-assisted Stirling heat pump is mainly driven by engine shaft power and is partially assisted by thermal power provided by engine exhaust heat. By proportioning the two energy sources to match the characteristics of the driving engine, the heat pump is supplied with the maximum share of the original energy fueling the engine. Developing the system will establish freon-free thermal utilization system technology that satisfies both wide heat demands and various fuel systems. (orig.)

Medical supply during military operations has the ability to affect the efficacy of the operation being undertaken, either negatively or positively. An appropriately-managed maritime platform with a robust medical supply chain during transit and on arrival in theatre is the main aim. A secure supply chain will reduce any implications that logistics may have with regard to capability, and negate the effects of deficiencies of short shelf life items occurring over time and during use in high tempo operations.

Unintended pregnancy is a major public health problem in the United States.Correct contraceptive use can reduce the rate of unintended pregnancy. Community pharmacies are well positioned to provide contraceptives and advice about contraception. To determine young women's perceptions and experiences with contraception supply in community pharmacies and to identify whether pharmacy characteristics predicted very positive experiences. This study comprised two cross-sectional surveys including an online women's pharmacy perceptions and experiences (PPE) survey and a faxed/observed survey of community pharmacies. One county in Michigan. Young women and community pharmacies. The two surveys were merged to explore pharmacy characteristics that may impact women's perceptions and experiences with community pharmacies. Multiple logistic regression analysis was used to explore relationships between pharmacy characteristics and positive outcomes. The response rate for the PPE survey was 54% (n = 343/637). Data from all community pharmacies in the county was retrieved via fax (n = 41/94, 43.6%) or observation (n = 53/94, 56.4%). Women were included in this analysis if they indicated a regular pharmacy (one they go to most often) in the county of interest (n = 210). More than 50% of women (n = 125/210) visited a pharmacy more than once per month. Sixty percent of women were currently using something to prevent pregnancy (n = 124/210, 60.8%). Thirty-five percent of women had a positive experience (n = 73/210, 34.8%). In the multiple logistic regression, women who visited a chain pharmacy had almost 65% lower odds of an overall positive experience with their regular pharmacy compared with women who visited a grocery or mass merchandise pharmacy (odds ratio 0.35 [95% CI 0.16], P = 0.75). Young women visit community pharmacies and use contraceptives frequently. Interventions need to be developed and implemented to improve young women's perceptions and experiences with

Our experience with implantation of VentrAssist left ventricular assist device

Full Text Available Perioperative anaesthetic management of the VentrAssist TM left ventricular assist device (LVAD is a challenge for anaesthesiologists because patients presenting for this operation have long-standing cardiac failure and often have associated hepatic and renal impairment, which may significantly alter the pharmacokinetics of administered drugs and render the patients coagulopathic. The VentrAssist is implanted by midline sternotomy. A brief period of cardiopulmonary bypass (CPB for apical cannulation of left ventricle is needed. The centrifugal pump, which produces non-pulsatile, continuous flow, is positioned in the left sub-diaphragmatic pocket. This LVAD is preload dependent and afterload sensitive. Transoesophageal echocardiography is an essential tool to rule out contraindications and to ensure proper inflow cannula position, and following the implantation of LVAD, to ensure right ventricular (RV function. The anaesthesiologist should be prepared to manage cardiac decompensation and acute desaturation before initiation of CPB, as well as RV failure and severe coagulopathic bleeding after CPB. Three patients had undergone implantation of VentrAssist in our hospital. This pump provides flow of 5 l/min depending on preload, afterload and pump speed. All the patients were discharged after an average of 30 days. There was no perioperative mortality.

Barooah, Adrita; Boerner, Kathrin; van Riesenbeck, Isabelle; Burack, Orah R

2015-01-01

This study examined certified nursing assistants' (CNAs) experiences of nursing home practices following resident death. Participants were 140 CNAs who had experienced recent resident death. In semi-structured, in-person interviews, CNAs were asked about their experiences with the removal of the resident's body, filling the bed with a new resident, and how they were notified about the death. The facilities' practice of filling the bed quickly was most often experienced as negative. Responses to body removal and staff notification varied, but negative experiences were reported by a substantial minority. Being notified prior to returning to work was associated with a more positive experience. Learning about the death by walking into a room to find the bed empty or already filled was the most negative experience. Study findings suggest that more mindful approaches to the transitions related to resident deaths would be valued by CNAs and could improve their work experience. Copyright © 2015 Elsevier Inc.

A growing body of evidence shows that existential and spiritual well-being in cancer patients is associated with better medical outcomes, improved quality of life, and serves as a buffer against depression, hopelessness, and desire for hastened death. Historical and recent research suggests a role for psilocybin-assisted psychotherapy in treating cancer-related anxiety and depression. A double-blind controlled trial was performed, where 29 patients with cancer-related anxiety and depression were randomly assigned to treatment with single-dose psilocybin (0.3 mg/kg) or niacin in conjunction with psychotherapy. Previously published results of this trial demonstrated that, in conjunction with psychotherapy, moderate-dose psilocybin produced rapid, robust, and enduring anxiolytic, and anti-depressant effects. Here, we illustrate unique clinical courses described by four participants using quantitative measures of acute and persisting effects of psilocybin, anxiety, depression, quality of life, and spiritual well-being, as well as qualitative interviews, written narratives, and clinician notes. Although the content of each psilocybin-assisted experience was unique to each participant, several thematic similarities and differences across the various sessions stood out. These four participants' personal narratives extended beyond the cancer diagnosis itself, frequently revolving around themes of self-compassion and love, acceptance of death, and memories of past trauma, though the specific details or narrative content differ substantially. The results presented here demonstrate the personalized nature of the subjective experiences elicited through treatment with psilocybin, particularly with respect to the spiritual and/or psychological needs of each patient.

Polycentrism and Poverty: Experiences of Rural Water Supply Reform in Namibia

Directory of Open Access Journals (Sweden)

Thomas Falk

2009-02-01

This paper investigates how polycentric rural water supply reform impacts on natural resource management and water users’ livelihoods in three communal areas of Namibia. The analysis takes into account the effects of historic discriminative policies and the resulting low financial, human and social capital of rural communities. We conclude that the devolution of institutional and financial responsibility for water supply to users has had a positive impact on rural water management. However, the introduction of cost recovery principles conflicts with the objectives of the Namibian government to alleviate poverty and inequality. The high level of inequality within the country as a whole and also within communities impedes the development of fair fee systems. Polycentrism faces the major challenge of building on existing structures without replicating historic injustices. It allows, however, for the state to mitigate any negative impact on livelihoods. While the reform is in the process of full implementation, the government is discussing various options of how the poor can be guaranteed access to water without diminishing their development opportunities. The Namibian experience demonstrates the difficulties in developing effective incentive mechanisms without undermining major social objectives. Our analyses show that, compared to naive monocentric governance approaches, polycentrism offers much broader opportunities for achieving multidimensional objectives. Nonetheless, a reform does not become successful simply because it is polycentric.

Selenium (Se) is a necessary trace element for humans and animals, and Se fertilization is an efficient way to increase Se concentration in the edible parts of crops, thus enhance the beneficiary effects of Se in human and animal health. Due to the similarity of physical and chemical properties between phosphate () and selenite (), phosphorus (P) supply often significantly impacts the absorption of Se in plants, but little is known about how P supply influences the subcellular distribution and chemical forms of Se. In this study, the effects of P supply on subcellular distribution and chemical forms of Se in winter wheat were investigated in a hydroponic trial with medium Se level (0.1 mg Se L -1 ). P was applied with three concentrations (0.31, 3.1, and 31 mg P L -1 ) in the experiment. The results showed that increasing P supply significantly decreased the concentration and accumulation of Se in the roots, stems, and leaves of winter wheat. An increase in P supply significantly inhibited Se accumulation in the root cell wall, but enhanced Se distribution in the organelles and soluble fraction of root cells. These findings suggest that increased P supply inhibited the root-to-shoot transport of Se. An increase in P supply enhanced Se accumulation in the cell wall of plant stems (both apical and axillary stem) and cell organelles of plants leaves, but inhibited Se distribution in the soluble fraction of stems and leaves. This suggests that P supply enhances Se transportation across the cell membrane in shoots of winter wheat. In addition, increased P supply also altered the chemical forms of Se in tissues of winter wheat. These findings will help in understanding of the regulation grain Se accumulation and provide a practical way to enhance Se intake for humans inform Se-enriched grains.

Individual Experiences in Four Cancer Patients Following Psilocybin-Assisted Psychotherapy

Directory of Open Access Journals (Sweden)

Tara C. Malone

2018-04-01

Full Text Available A growing body of evidence shows that existential and spiritual well-being in cancer patients is associated with better medical outcomes, improved quality of life, and serves as a buffer against depression, hopelessness, and desire for hastened death. Historical and recent research suggests a role for psilocybin-assisted psychotherapy in treating cancer-related anxiety and depression. A double-blind controlled trial was performed, where 29 patients with cancer-related anxiety and depression were randomly assigned to treatment with single-dose psilocybin (0.3 mg/kg or niacin in conjunction with psychotherapy. Previously published results of this trial demonstrated that, in conjunction with psychotherapy, moderate-dose psilocybin produced rapid, robust, and enduring anxiolytic, and anti-depressant effects. Here, we illustrate unique clinical courses described by four participants using quantitative measures of acute and persisting effects of psilocybin, anxiety, depression, quality of life, and spiritual well-being, as well as qualitative interviews, written narratives, and clinician notes. Although the content of each psilocybin-assisted experience was unique to each participant, several thematic similarities and differences across the various sessions stood out. These four participants’ personal narratives extended beyond the cancer diagnosis itself, frequently revolving around themes of self-compassion and love, acceptance of death, and memories of past trauma, though the specific details or narrative content differ substantially. The results presented here demonstrate the personalized nature of the subjective experiences elicited through treatment with psilocybin, particularly with respect to the spiritual and/or psychological needs of each patient.

Green supply chain management strategies - experiences from the Danish textile sector

DEFF Research Database (Denmark)

Forman, Marianne; Jørgensen, Michael Søgaard

This paper focuses on Danish textile industry experiences with setting environmental requirements throughout the supply chain. Based on a qualitative study, three models were formulated for the development of environmental competency in the product chain. The models centre on the environmental...... to their potential contribution to a long-term environmental effort, including how the models contribute to the spread of environmental competency etc. to other textile companies, as well as how certain model aspects ensure/hinder stabilisation of the product chain, including the interaction between social, economic......, legal, and environmental variables, among others. This last theme is central as it says much about the durability of the models and the inherent risk factors with regard to the organisations involved. The first section of this article will outline the background and status of environmental efforts...

Attitudes towards assisted dying are influenced by question wording and order: a survey experiment.

Science.gov (United States)

Magelssen, Morten; Supphellen, Magne; Nortvedt, Per; Materstvedt, Lars Johan

2016-04-27

Surveys on attitudes towards assisted dying play an important role in informing public debate, policy and legislation. Unfortunately, surveys are often designed with insufficient attention to framing effects; that is, effects on the respondents' stated attitudes caused by question wording and context. The purpose of this study was to demonstrate and measure such framing effects. Survey experiment in which an eight-question survey on attitudes towards assisted dying was distributed to Norwegian citizens through a web-based panel. Two variations of question wording as well as two variations of question order were employed. Respondents were randomized to receive one of four questionnaire versions. Three thousand and fifty responses were received. There were moderate to large question wording and question order effects. A majority of Norwegian citizens favour the legalization of assisted dying for patients with terminal or chronic disease. Stakeholders in the assisted dying debate need to acknowledge potential framing effects, and accordingly should interpret survey results with caution. The same holds for researchers who conduct attitude surveys in the field of bioethics.

Security of supply in liberated electricity markets - key issues and experiences in OECD countries (work in progress)

International Nuclear Information System (INIS)

Stridbaek, Ulrik

2005-06-01

Security of supply of electricity could in principle refer to any parts of the value chain from fuel input to delivery of electricity to the final costumer with the expected quality. Concerns about security of supply are usually focused on three aspects: Timely and adequate supply of the input fuel for electricity generation is a prerequisite - security of energy supply. There has to be timely and adequate infrastructure in place to transform the input fuel into electricity and transport it to the final costumer - adequacy of generation and transmission capacity. Finally, it is an operational challenge to make the electricity system work and deliver at the expected quality - secure operation of the electricity system. Security of supply becomes relevant in a policy context from concerns about market failures in any parts of the value chain or, indeed, from the perspective that policy will set the framework for markets to serve as an instrument to secure the supply. This paper discusses some of the experiences with security of supply concerns and market failures in these three basic segments of the value chain; fuel input, adequate generation and transmission capacity and secure operation of the system, with an emphasis on the role of the market to serve as an efficient instrument. In the aftermath of the large black outs of electricity systems in North America, Italy and Sweden/Denmark IEA initiated a project on 'Transmission Reliability and Power System Security in Competitive Electricity Markets'. The results of this work will be published towards the end of 2005. After a decade with liberalised electricity markets in some pioneer regions, IEA now also finds it timely to analyse some of the lessons in a forthcoming publication. Recent and ongoing IEA-work thereby covers all the main aspects of security of supply. This paper summarises the key findings and messages, with a focus on the work in progress on lessons from liberalisation

De, T.K.

2005-01-01

Large scale indigenous production of power supplies started at VECC since 1970. At a later stage, compact Superconducting Cyclotron demanded highly stable (of the order of 20 ppm) magnet power supplies to accommodate a large number of highly precise distributed beam trajectory in a smaller radial distance. Intensive quality development around the power supplies became essential. In-depth understanding of the power supply components, modules, computer based simulation, design, instrumentation, wide and long experience, all put together have contributed remarkable results leading to high quality indigenous development of power supply at VECC - a brief report has been presented in this paper.

Costa, Karen Sarmento; Nascimento, José Miguel do

2012-12-01

To analyze results of the Horus Information System, comparing elements of this system with some international experiences. Horus is a technological innovation introduced in 2009 in the Pharmaceutical management information system of the Sistema Único de Saúde (Brazilian Unified Health System). In 2011, local managers and health professionals of 1,247 municipalities (16 states) that adhered to Horus answered questionnaires on pharmaceutical assistance in primary care and about the Horus system. This is a descriptive and exploratory study, developed with the use of quantitative and qualitative methods of research. Multivariate tools were used for data collection and interpretative support of the statistical inference and thematic analysis. The main changes identified after the implementation of this system were: improvement on technical and scientific quality control of Pharmaceutical Assistance, improvement on the supply of medications and health care; training of human resources and knowledge management; improvement on the relationship health managers/users; development in the administrative management and greater inter-state management; and improvement on the technological infrastructure. In terms of health information systems, these categories are consistent with programs and obstacles observed in international experiences. The biggest gap identified was the fact that Horus was not included in a national policy of health information systems, which is in a process of consolidation in Brazil. The national database of actions and services within the Pharmaceutical Assistance will enable the collection, analysis and dissemination of information regarding integrated pharmaceutical assistance in the Brazilian context. The Horus System is a technological innovation that enables the management of the Pharmaceutical Assistance. The national base will enable the definition and agreement on national indicators of Pharmaceutical Assistance, aiming to produce evidence of

von Segesser, L K; Tkebuchava, T; Leskosek, B; Marty, B; Pei, Y C; Turina, M

1997-01-01

Left ventricular assist systems with portable drive units are increasingly used in the clinical setting. However, such systems usually are not suitable for right ventricular support, and therefore, in the case of biventricular heart failure, they must be combined with other support devices that require additional drive consoles. As a result, most of the benefits of the wearable drive units (early mobilization and outpatient care) are lost. This present study was performed to evaluate biventricular support with implanted assist devices and a portable DC/battery-powered driver (Thoratec TLC-II). Electronic control by nonvolatile RAM accessible via RS232 interface, internal backup emergency battery, and optional manual activation are additional features of this 6 kg biventricular drive unit. In 3 bovine experiments (body weight 70 +/- 5 kg) partial cardiopulmonary bypass (CPB) was established, and two ventricular assist devices were implanted into a preperitoneal pocket on each side after connection to the right atrium and the pulmonary artery and to the left atrium and aorta, respectively. After weaning the patient from CPB, activated coagulation time (ACT) was kept at greater than 180 s, and biventricular support with the portable driver was activated. After 10 min, mean device flow stabilized at 3.5 +/- 0 L/min and remained at that level throughout the ensuing 6 h (3.5 +/- 0.3 L/min; NS). The heart rate moved from 130 +/- 13 beats per minute (bpm) at the end of CPB to 116 +/- 13 bpm after 10 min of assist (p < 0.05). Right atrial pressure moved from 11 +/- 2 mm Hg at the end of CPB to 13 +/- 3 mm Hg after 10 min of assist (not significant [NS]). Mean pulmonary artery pressure was 18 +/- mm Hg at the end of CPB and 17 +/- 5 mm Hg after 10 min of assist (NS). Left atrial pressure was 10 +/- 1 mm Hg at the end of CPB and 13 +/- 3 mm Hg after 10 min of assist (NS). Mean aortic pressure was 73 +/- 11 mm Hg at the end of CPB and 77 +/- 3 mm Hg after 10 min of assist (NS

2018-02-01

Full Text Available After a hiatus of some 40 years, clinical research has resumed on the use of classic hallucinogens to treat addiction. Following completion of a small open-label feasibility study, we are currently conducting a double-blind placebo-controlled clinical trial of psilocybin-assisted treatment of alcohol use disorder. Although treatment effects cannot be analyzed until the study is complete, descriptive case studies provide a useful window into the therapeutic process of psychedelic-assisted treatment of addiction. Here we describe treatment trajectories of three participants in the ongoing trial to illustrate the range of experiences and persisting effects of psilocybin treatment. Although it is difficult to generalize from a few cases, several qualitative conclusions can be drawn from the data presented here. Although participants often find it difficult to describe much of their psilocybin experience, pivotal moments tend to be individualized, extremely vivid, and memorable. Often, the qualitative content extends beyond the clinical problem that is being addressed. The participants discussed in this paper experienced acute and lasting alterations in their perceptions of self, in the quality of their baseline consciousness, and in their relationship with alcohol and drinking. In these cases, experiences of catharsis, forgiveness, self-compassion, and love were at least as salient as classic mystical content. Finally, feelings of increased “spaciousness” or mindfulness, and increased control over choices and behavior were reported following the drug administration sessions. Ultimately, psilocybin-assisted treatment appears to elicit experiences that are extremely variable, yet seem to meet the particular needs of the individual.

2003-11-01

The purpose of this study was to evaluate a new method for performing MRI-guided vacuum-assisted breast biopsy in a study of lesions that had subsequent surgical excision. SUBJECTS AND METHODS. Twenty women scheduled for MRI-guided needle localization and surgical biopsy were prospectively entered in the study. MRI-guided biopsy was performed with a vacuum-assisted probe, followed by placement of a localizing clip, and then needle localization for surgical excision. Vacuum-assisted biopsy and surgical histology were correlated. Vacuum-assisted biopsy was successfully performed in 19 (95%) of the 20 women. The median size of 27 MRI-detected lesions that had biopsy was 1.0 cm (range, 0.4-6.4 cm). Cancer was present in eight (30%) of 27 lesions and in six (32%) of 19 women; among these eight cancers, five were infiltrating and three were ductal carcinoma in situ (DCIS). Among these 27 lesions, histology was benign at vacuum-assisted biopsy and at surgery in 19 (70%), cancer at vacuum-assisted biopsy in six (22%), atypical ductal hyperplasia at vacuum-assisted biopsy and DCIS at surgery in one (4%), and benign at vacuum-assisted biopsy with surgery showing microscopic DCIS that was occult at MRI in one (4%). The median time to perform vacuum-assisted biopsy of a single lesion was 35 min (mean, 35 min; range, 24-48 min). Placement of a localizing clip, attempted in 26 lesions, was successful in 25 (96%) of 26, and the clip was retrieved on specimen radiography in 22 (96%) of 23. One complication occurred: a hematoma that resolved with compression. MRI-guided vacuum-assisted biopsy is a fast, safe, and accurate alternative to surgical biopsy for breast lesions detected on MRI.

Early operating and reliability experience with the CEBAF DC magnet power supplies

International Nuclear Information System (INIS)

Merz, W.; Flood, R.; Martin, E.J.; O'Sullivan, M.

1996-01-01

The CEBAF accelerator is a five pass, recirculating, CW electron linear accelerator. There are a total of nine recirculation arcs connecting the two linacs. Three experimental halls are serviced by the accelerator through separate transport channels. The magnet powering system for CEBAF consists of approximately 2000 independent control channels. About 1850 of these channels are low current, trim magnet power supplies. There are 28 higher power supplies used to energize the major bending elements. Over one hundred, 20 amp, active shunts are used to vary current in selected magnets in the major dipole strings. The majority of the magnetic elements are concentrated in the arcs and transport channels. The correction dipoles, quadrupoles and sextupoles are each powered individually be a dedicated trim power supply channel. The arc and extraction channel dipoles are powered in series strings by the high powered supplies, known locally at CEBAF as 'box power supplies'. Arc loads consist of some 30--40 magnets in series. Transport channel, path length control doglegs and septa box power supplies have loads ranging from 1 to 10 magnets. Shunts are installed on virtually all loads where two or more magnets are in series. At this time, 95% of the power supplies are installed and commissioned. In the past twelve months, beginning in May 1994, approximately 1200 trim magnet power supplies have been checked out. During this same period approximately 22 box power supplies and 100 shunts have been made operational. Full operation of the equipment has only been under way since early 1995. While this operation is only just beginning, much has been learned based on the reliability performance seen so far. The remainder of this paper describes the systems mentioned, their reliability problems, the fixes implemented to date, and some plans for the future. 6 refs., 3 tabs

Evidence suggests that immunization supply chains are becoming outdated and unable to deliver needed vaccines due to growing populations and new vaccine introductions. Redesigning a supply chain could result in meeting current demands. The Ministries of Health in Benin in Mozambique recognized known barriers to the immunization supply chain and undertook a system redesign to address those barriers. Changes were made to introduce an informed push system while consolidating storage points, introducing transport loops, and increasing human resource capacity for distribution. Evaluations were completed in each country. Evaluation in each country indicated improved performance of the supply chain. The Effective Vaccine Management (EVM) assessment in Benin documented notable improvements in the distribution criteria of the tool, increasing from 40% to 100% at the district level. In Mozambique, results showed reduced stockouts at health facility level from 79% at baseline to less than 1% at endline. Coverage rates of DTP3 also increased from 68.9% to 92.8%. Benin and Mozambique are undertaking system redesign in order to respond to constraints identified in the vaccine supply chain. Results and learnings show improvements in supply chain performance and make a strong case for system redesign. These countries demonstrate the feasibility of system redesign for other countries considering how to address outdated supply chains. Copyright © 2017 The Author(s). Published by Elsevier Ltd..

Gas markets and security of supply

International Nuclear Information System (INIS)

Gibot, G.

1997-01-01

In the natural gas business, some European states and companies seem to be concerned by security of supply. Security of supply for a governmental organisation is discussed, to share the author's conception and experience. The targets of a security of supply policy and the measures that can be set are described. The possible changes in implementing this policy are considered, according to recent developments in the field of gas security. The specificity of European gas markets justify the concern in security of supply, as concluded the Commission and the IEA. The integration of national gas markets in Europe will give new opportunities for managing this security of supply. (R.P.)

The function of the service power system of a nuclear power plant is to provide safe and reliable power supply for the nuclear power plant facilities. The safety of nuclear power plant power supply is essential for nuclear safety. The serious accident of Fukushima Daiichi nuclear power plant occurred due to loss of service power and the ultimate heat sink. The service power system has two independent offsite power supplies as working power and auxiliary power. This article collected events of loss of offsite power supply in operating nuclear power plants at home and abroad, and analyzed the plant status and cause of loss of offsite power supply events, and proposed improvement measures for dealing with loss of offsite power supply.

Rural power supply with local management: Examples from Bolivia, India and Nepal

Energy Technology Data Exchange (ETDEWEB)

Gerger, Aa; Gullberg, M

1997-08-01

Local management of rural power supply is being evaluated in a joint research project conducted by Tanzania Electric Supply Company Limited (TANESCO) and Stockholm Environment Institute (SEI) on new approaches to management and organization of rural electrification. The study is based on literature, and on data from eight visited local organizations for management of power supply in Bolivia (4), India (1) and Nepal (3). Common for these countries is that the national, rural electrification programmes have encountered difficulties. Governments have failed to generate enough funds from existing power supply systems to cover the cost for a continued rural electrification. In cases where large private companies exist, they have had few incentives for expanding into rural areas since it is often not profit making. A third category may be defined as local initiators to power supply, private or co-operative. In all these countries, locally managed power supply systems have developed as a complement to governmental and other large scale programmes. The national policies pertaining to rural power supply in general and local management thereof in particular are described for each country. From the study, it appears that local management of rural power supply is a feasible approach in developing countries. Local management of rural power supply can slightly lower the costs of electrification, and it may help accelerate the pace of load development in newly electrified areas. For successful local organizations though, the most significant factor appears to be local peoples` willingness to develop their own area. Important though, is that proper financial and technical assistance is provided the local organizations. Crucial for sound external assistance is that the national rural electrification policies are clear and consistent. 53 refs, 1 fig, 11 tabs

Work Floor Experiences of Supply Chain Partnering in the Dutch Housing Sector

Directory of Open Access Journals (Sweden)

Marieke Venselaar

2017-11-01

consider SCP in construction industry as an emergent practice is relatively scarce. It is said that current literature on this topic is stylized and too abstracted from daily work practice. Individual experiences are averaged away in an attempt to develop a general theory. There is too little insight in what people actually do in daily work practice and how they form a strategy such as SCP. Work floor experiences of SCP should be studied, because without the insight, it is difficult (if not impossible to intervene in an efficient and effective way and to improve performances. To study work floor experience of SCP, a specific part of the construction sector was chosen. After all, experiences in different fields may differ. This study focuses on Dutch housing associations. Dutch housing associations own a third of the total Dutch housing stock. Being one of the biggest clients, they dominate the sector. Due to several reasons, Dutch housing associations have to cut back expenditures. Supply chain partnering is one way to try to do this. Within the context of Dutch housing associations, we chose to study the work floor experiences of the project leaders, because project leaders are important in translating principles of SCP into daily work floor routines. Thus, the problem is that not enough attention has been paid to what goes on at work floor level when project leaders try to apply principles of supply chain partnering. This insight is necessary, because supply chain partnering is formed by ongoing processes of interactions between professionals in daily work practice. Therefore, to improve performances and intervene effectively, insight in work floor practices should increase. This research aims to describe work floor experiences of professionals who work for Dutch housing association and who attempt to apply SCP. To reach this target the following question will be answered: What are work floor experiences of project leaders that work for Dutch housing associations who try

Full Text Available Standard medical curricula in the United Kingdom (UK typically provide basic surgical-skills teaching before medical students are introduced into the clinical environment. However, these sessions are often led by clinical teaching fellows and/or consultants. Depending on the roles undertaken (e.g., session organizers, peer tutors, a peer-assisted learning (PAL approach may afford many benefits to teaching surgical skills. At the University of Keele's School of Medicine, informal PAL is used by the Surgical Society to teach basic surgical skills to pre-clinical students. As medical students who assumed different roles within this peer-assisted model, we present our experiences and discuss the possible implications of incorporating such sessions into UK medical curricula. Our anecdotal evidence suggests that a combination of PAL sessions – used as an adjunct to faculty-led sessions – may provide optimal learning opportunities in delivering a basic surgical skills session for pre-clinical students.

Industry experience a need to shift in focus from internal production planning towards planning in the supply network. In this respect customer oriented thinking becomes almost a common good amongst companies in the supply network. An increase in the use of information technology is needed to enable companies to better tune their production planning with customers and suppliers. Information technology opportunities and supply chain planning systems facilitate companies to monitor and control their supplier network. In spite if these developments, most links in today's supply chains make individual plans, because the real demand information is not available throughout the chain. The current systems and processes of the supply chains are not designed to meet the requirements now placed upon them. For long term relationships with suppliers and customers, an integrated decision-making process is needed in order to obtain a satisfactory result for all parties. Especially when customized production and short lead-time is in focus. An effective value chain makes inventory available and visible among the value chain members, minimizes response time and optimizes total inventory value held throughout the chain. In this paper a supply chain planning classification grid is presented based current manufacturing classifications and supply chain planning initiatives.

Full Text Available Orientation: In today’s globalised and complex business environment, firms are ever more vulnerable to supply chain disruptions, originating both internally and externally from the supply chain. Supply chain resilience minimises the impact of a disruption through design approaches, which allows the supply chain to respond appropriately to disruptive events. Research purpose: This article investigated the supply chain risks faced by grocery manufacturers in the South African fast-moving consumer goods (FMCG industry and explored supply chain design approaches that enable supply chain resilience. Motivation for the study: South African grocery manufacturers are faced with distinct risks. Whilst supply chain risk management studies have provided firms with certain guidelines to mitigate risk, supply chains are still vulnerable to unanticipated risks. Literature on supply chain resilience in the South African context is scant. The concept of supply chain resilience provides firms with strategies that are built into the supply chain that allow firms to react and recover swiftly from disruptions. Furthermore, supply chain resilience strategies assist firms in becoming less vulnerable to possible disruptions. Research design approach and method: This study was conducted by using a descriptive qualitative research design. Data were collected through semi-structured interviews with senior supply chain practitioners specifically within the South African FMCG grocery manufacturing industry. Main findings: The study found that labour unrest is the most common risk faced by the industry. Furthermore, strategic stock and supply chain mapping are of the most useful design approaches to enhance supply chain resilience. Practical/managerial implications: The study provides managers with new insights in guiding supply chain design decisions for resilient supply chains. Through the identification of risks and appropriate solutions linked to the various risks

The paper explores the effects of the social security system over retirement and labor supply decision of individuals aged 55 to 65 in Chile. We use the 1998 CASEN survey elaborated by the Chilean government. Due to regulations established by the current social security law, two social security systems coexist on 1998: the .Pay-as-you-go. and the individual account system. This property of the dataset, allows us to disentangle the effects of those two systems over retirement and labor supply....

Modelling Lean and Green Supply Chain

Science.gov (United States)

Duarte, Susana Carla Vieira Lino Medina

The success of an organization depends on the effective control of its supply chain. It is important to recognize new opportunities for organization and its supply chain. In the last few years the approach to lean, agile, resilient and green supply chain paradigms has been addressed in the scientific literature. Research in this field shows that the integration of these concepts revealed some contradictions among so many paradigms. This thesis is mainly focused on the lean and green approaches. Thirteen different management frameworks, embodied in awards, standards and tools were studied to understand if they could contribute for the modelling process of a lean and green approach. The study reveals a number of categories that are common in most management frameworks, providing adequate conditions for a lean and green supply chain transformation. A conceptual framework for the evaluation of a lean and green organization`s supply chain was proposed. The framework considers six key criteria, namely, leadership, people, strategic planning, stakeholders, processes and results. It was proposed an assessment method considering a criteria score for each criterion. The purpose is to understand how lean and green supply chain can be compatible, using principles, practices, techniques or tools (i.e. elements) that support both, a lean and a green approach, in all key criteria. A case study in the automotive upstream supply chain was performed to understand more deeply if the elements proposed for the conceptual framework could be implemented in a real-scenario. Based on the conceptual framework and the case study, a roadmap to achieve a lean-green transformation is presented. The proposed roadmap revealed its contribution to the understanding on how and when an organization`s supply chain should apply the lean and green elements. This study is relevant to practice, as it may assist managers in the adoption of a lean and green supply chain approach, giving insights for the

Objective: To retrospectively summarize the technical experience in performing catheter-assisted retrieval of adhesive Geunther Tulip filter. Methods: During the period from November 2007 to October 2009, 95 patients with pulmonary embolism and acute deep vein thrombosis of lower limbs were admitted to authors' hospital. As simple snare technique failed to catch the adhesive Geunther Tulip filter previously implanted in inferior vena cava (IVC) in 6 patients (four males and two females with a mean age of 43.7 years), catheter-assisted retrieval of adhesive Geunther Tulip filter had to be carried out. The specific procedure was as follows. After phlebography of IVC confirmed that the filter's retrieval hook had adhered to IVC wall, the adhesion was separated with the help of catheter as well as goose-neck capturing device, then, the Geunther Tulip filter was retrieved. After the procedure, both anticoagulation and antibiotic medication were employed for 3-5 days. All the patients were followed up for 4-12 months. Vascular ultrasonography and pulmonary 3D CTA were re-examined in 6 months after primary operation. Results: All 6 adhesive Geunther Tulip filters were successfully removed with a success rate of 100%. The manipulation used in the procedure included catheter-twisting technique (n=1), catheter-looping technique (n=1) and catheter-snare looping technique (n=4). The mean operation time was 40.5 minutes (in the range of 17-78 minutes). The average filter-dwelling time was 46.7 days (ranging from 14 to 80 days). No thrombus formation in deep veins of lower extremity or pulmonary embolism occurred during the follow-up period. Conclusion: The catheter-assisted retrieval technique carries high retrieval rate for adhesive Geunther Tulip filter in IVC, it can markedly improve the retrieval success rate of Tulip IVC filter.

Interventions to tackle the supply of drugs are seen as standard components of illicit drug policies. Therefore drug market-related administrative data, such as seizures, price, purity and drug-related offending, are used in most countries for policy monitoring and assessment of the drug situation. International agencies, such as the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) and the UN Office of Drugs and Crime, also monitor and report on the drug situation cross-nationally and therefore seek to collect and make available key data in a uniform manner from the countries they cover. However, these data are not primarily collected for this purpose, which makes interpretation and comparative analysis difficult. Examples of limitations of these data sources include: the extent to which they reflect operational priorities rather than market changes; question marks over the robustness of and consistency in data collection methods, and issues around the timeliness of data availability. Such problems are compounded by cultural, social and contextual differences between countries. Making sense of such data is therefore challenging and extreme care needs to be taken using it. Nevertheless, these data provide an important window on a hidden area, so improving the quality of the data collected and expanding its scope should be a priority for those seeking to understand or monitor drug markets and supply reduction. In addition to highlighting some of the potential pitfalls in using supply indicators for comparative analysis, this paper presents a selection of options for improvements based on the current EMCDDA programme of work to improve their supply-related monitoring and analysis. The conceptual framework developed to steer this work may have wider application. Adopting this approach has the potential to provide a richer picture of drug markets, at both national and international levels, and make it easier to compare data between countries. Copyright �

NEA activities on medical isotope supply issues

International Nuclear Information System (INIS)

Westmacott, C.; Vance, R.

2009-01-01

Medical radioisotopes play a vital role in modern medical practices. One of their principal uses is for nuclear diagnostic imaging techniques. These techniques are powerful and non-invasive, allowing the identification of common diseases such as heart conditions and cancer at an early stage, tracking disease progression and providing predictive information about likely success of a therapy. Such techniques enable precise and accurate management of the disease and may significantly assist in the medical decision-making process, for example removing the need for surgical intervention to obtain diagnostic information. Every year, 46 million people are estimated to benefit globally from such nuclear medicine testing. However, over the last few years there have been a number of supply shortages of Molybdenum-99 (Mo-99) and its decay product, Technetium-99m (Tc-99m), the most widely used medical radioisotope. These isotopes decay within a matter of days; therefore they must be produced continually in order to meet demand. Most recently, the unexpected extended shutdown of Canada's NRU research reactor - which produces approximately 35 percent of world Mo-99 supply - has compounded existing concerns regarding the supply reliability of these medical radioisotopes. Currently, five reactors between 42 and 52 years old produce over 95 percent of the world's supply of Mo-99 and face challenges in maintaining a continuous supply to the health community. As outlined above, disruptions in this supply chain have affected the availability of vital medical testing for millions of patients around the world. On 29-30 January 2009, the NEA hosted a workshop on Security of Supply of Medical Radioisotopes at the request of the Government of Canada. The workshop assembled an international group of experts to identify challenges faced in providing a reliable supply of Mo-99 and Tc-99m and measures that should be taken to ensure such reliability. Workshop participants discussed a wide

Cost-effectiveness of open versus laparoscopic versus robotic-assisted laparoscopic cystectomy and urinary diversion.

To provide insight into the recently published cost comparisons in the context of open, laparoscopic, and robotic-assisted laparoscopic radical cystectomy and to demonstrate the complexity of such economic analyses. Most economic evaluations are from a hospital perspective and summarize short-term perioperative therapeutic costs. However, the contributing factors (e.g. study design, included variables, robotic amortization plan, supply contract, surgical volume, surgeons' experience, etc.) vary substantially between the institutions. In addition, a real cost-effective analysis considering cost per quality-adjusted life-year gained is not feasible because of the lack of long-term oncologic and functional outcome data with the robotic procedure. On the basis of a modeled cost analysis using results from published series, robotic-assisted cystectomy was - with few exceptions - found to be more expensive when compared with the open approach. Immediate costs are affected most by operative time, followed by length of hospital stay, robotic supply, case volume, robotic cost, and transfusion rate. Any complication substantially impacts overall costs. Economic cost evaluations are complex analyses influenced by numerous factors that hardly allow an interinstitutional comparison. Robotic-assisted cystectomy is constantly refined with many institutions being somewhere on their learning curve. Transparent reports of oncologic and functional outcome data from centers of expertise applying standardized methods will help to properly analyze the real long-term benefits of robotic surgery and successor technologies and prevent us from becoming slaves of successful marketing strategies.

Xiao Xue

2015-01-01

Full Text Available Companies have been aware of the benefits of developing Cluster Supply Chains (CSCs, and they are spending a great deal of time and money attempting to develop the new business pattern. Yet, the traditional techniques for identifying CSCs have strong theoretical antecedents, but seem to have little traction in the field. We believe this is because the standard techniques fail to capture evolution over time, nor provide useful intervention measures to reach goals. To address these problems, we introduce an agent-based modeling approach to evaluate CSCs. Taking collaborative procurement as research object, our approach is composed of three parts: model construction, model instantiation, and computational experiment. We use the approach to explore the service charging policy problem in collaborative procurement. Three kinds of service charging polices are compared in the same experiment environment. Finally, “Fixed Cost” is identified as the optimal policy under the stable market environment. The case study can help us to understand the workflow of applying the approach, and provide valuable decision support applications to industry.

Mansi Jhamb

2017-02-01

Full Text Available The Body sensor network [IEEE 802.15] is a wireless communication network consisting of assistive devices which are of prime importance in medical applications. The delay critical and power hungry blocks in these assistive devices are designed so that they consume less power, have low latency and require a lesser area on chip. In this paper, we present a qualitative as well as a quantitative analysis of an asynchronous pipelined adder design with two latest computation completion sensing approaches based on Pseudo NMOS logic and other based on C-element. The Pseudo NMOS based completion sensing approach provides a maximum improvement of 76.92% in critical path delay at supply voltage of 1.2 V and the maximum drop in power dissipation has been observed at a supply voltage of 1.1 V which is 85.60% as compared to C-element based completion sensing approach. Even at low voltages such as 0.8 V, there is a significant improvement in speed and power which is 75.64% and 74.79% respectively. Since the adder is the most widely used component in all present day assistive devices, this analysis acts as a pointer for the application of asynchronous pipelined circuits with efficient Pseudo NMOS based completion sensing approach in low voltage/low power rehabilitative devices.

In this sense, the research intend to expand knowledge related to supply chain management in the area of ​​provision of healthcare services through the use of the philosophy of continuous improvement and lean principles, helping healthcare to provide quality service within their current budget constraints.

Power supply in future: ecological aspects

International Nuclear Information System (INIS)

Hustedt, M.

2000-01-01

The most important prerequisites for an ecological supply of energy in the future is the opting out of nuclear energy and the completion of the second and third phase of the socio-ecological tax reform. As a part of our energy will continue to be generated on the basis of fossil fuels in the foreseeable future, it is essential that a radical change takes place in the efficiency of fossil energy engineering. In addition to this, any possible energy-saving potential must be exploited; this includes the new energy-saving law, promoting the modernisation of old buildings and modern energy management (heat insulation, heating engineering, warm water heating etc.). For an ecological power supply the share of renewable energies must be increased to form a major pillar of our power supply. The '100,000-roof' programme of the German federal government and the development programme for near-market renewable energy sources form part of this approach. Energy research should shift its orientation and accelerate the conversion of our power supply: priority should be given to developing energy-saving technologies and renewable energy. Supporting municipalities and public utilities is especially important. This means revising the basic conditions of energy laws so that they assist public utilities to face competition as power utilities. (orig.) [de

2000-01-01

Experimental investigations were conducted on the direct expansion solar assisted Heat Pump (DESAHP). Refrigerant R-22 was expanded in the solar collector which also acted as the evaporator in a conventional vapor compression refrigerating machine. The experiments were conducted under conditions of high and low solar radiation, with evaporator completely shaded from the sun, and at night. System thermal performance was determined by measuring refrigerant flow rate, temperature and pressure at numerous points in the system. The results showed that 227-l of water could be heated from 3O degree to 55 degree C in about 105 minutes. Higher water temperatures were obtained during hot sunny days. The coefficient of performance of heating, COP h , ranged from 11 to 4.7, depending upon operating conditions. The total saving of electric energy during hot sunny days was about 460 %. It means that for 1 kWh of electrical input to the system, we achieve 4.6 kWh. This percentage decreases as the evaporator temperature decreases and is a function of solar energy input. (Author)

Han, B.M.; Karady, G.G.; Thiessen, H.A.

1989-01-01

The particles in a Rapid Cycling Accelerator are accelerated by rf cavities, which are tuned by dc biased ferrite cores. The tuning is achieved by the regulation of bias current, which is produced by a power supply. The tuning magnet power supply utilizes a bridge circuit, supplied by a three phase rectifier. During the rise of the current, when the particles are accelerated, the current is controlled with precision by the bridge which operates a power amplifier. During the fall of the current, the bridge operates in a switching mode and recovers the energy stored in the ferrites. The recovered energy is stored in a capacitor bank. The bridge circuit is built with 150 power transistors. The drive, protection and control circuit were designed and built from commercial component. The system will be used for a rf cavity experiment in Los Alamos and will serve as a prototype tuning power supply for future accelerators. 1 ref., 7 figs

Borgestig, Maria; Rytterström, Patrik; Hemmingsson, Helena

2017-07-01

To describe and explore parents' experiences when their children with severe physical impairments receive gaze-based assistive technology (gaze-based assistive technology (AT)) for use in daily life. Semi-structured interviews were conducted twice, with one year in between, with parents of eight children with cerebral palsy that used gaze-based AT in their daily activities. To understand the parents' experiences, hermeneutical interpretations were used during data analysis. The findings demonstrate that for parents, children's gaze-based AT usage meant that children demonstrated agency, provided them with opportunities to show personality and competencies, and gave children possibilities to develop. Overall, children's gaze-based AT provides hope for a better future for their children with severe physical impairments; a future in which the children can develop and gain influence in life. Gaze-based AT provides children with new opportunities to perform activities and take initiatives to communicate, giving parents hope about the children's future.

Due to its high economic value and is produced by many countries, Tuna is considered as one of the world’s popular fish. Demand for Tuna species are very high and it usually sells in three form: fresh, frozen or canned. Competition in Tuna trading is challengin with the potential risk of price and supply fluctuations. With recent focus of Indonesia government that see the future of Indonesia civilization depend on the oceans and as the three biggest Tuna producing country, Ministry of Marine Affairs and Fisheries should ensure sustainability and competitiveness of Indonesian tuna. Therefore, there is a great need to develop a proper and effective strategy to manage potential risks in Indonesian Tuna supply chain. This paper is aimed at identifying and mapping potential Tuna supply chain risks and its interrelationships that would assist government in determining proper strategies to manage Indonesian Tuna. A framework for identifying Tuna supply chain risks is proposed. Generic risk structure of Supply Chain Risk Identification System is adopted and modified to match with particular object, which is Indonesian Tuna. The proposed model consists of hierarchical and causal structure that encompass potential risks of Tuna supply chain operations from fishing, trading, processing and distribution. The causal structure consist of risk events and its risk agents which is the cause of risk events. To ensure the root cause of risk events are identified properly, five why’s analysis is utilized to obtain risk agents. This proposed model also captures risk interrelationship between internal and external environment of Tuna supply chain. Preliminary result of this study identifies 15 risk events and 13 risk factors on fishing and trading operations and maps their interrelationships.

Full Text Available Reducing dependence on fossil fuels, alleviating environmental impacts and ensuring sustainable economic growth are among the most promising aspects of utilizing renewable energy resources. Biomass is a major renewable energy resource that has the potential for creating sustainable energy systems that are critical in terms of social welfare. Utilization of biomass for bioenergy production is an efficient alternative for meeting rising energy demands, reducing greenhouse gas emissions and thus alleviating climate change. A supply chain for such an energy source is crucial for assisting deliverance of a competitive end product to end-user markets. Considering the existing constraints, a mixed integer linear programming (MILP model for waste biomass based supply chain was proposed in this study for economic performance optimization. Performance of the proposed modelling approach was demonstrated with a real life application study realized in İstanbul. Moreover, sensitivity analyses were conducted which would serve as a foresight for efficient management of the supply chain as a whole

2013-12-06

This study was aimed to explore parents' experience of assisting children affected by tuberous sclerosis complex (TSC) with subependymal giant-cell astrocytoma (SEGA) manifestation, in order to understand their caring needs and expectation of support. The study was designed according to the qualitative method of interpretative description and implied two sequential phases of data collection. The first phase was based on in-depth interviews with 18 Italian caregivers of children living with TSC. The second phase of the research was based on an online forum with 30 caregivers of children living with TSC. 48 Italian caregivers, assisting patients with TSC with SEGA manifestation have been involved in the study. When a TSC diagnosis is made, the whole family is affected psychologically. TSC has a great impact on families' quality of life and on their ability to cope with the disease and support the child's ability to recover and reach an acceptable level of well-being. Caregivers report the experience of losing control and the feeling of loneliness and abandon from the healthcare system. Families of children affected by TSC need targeted psychosocial assistance in order to support patients and caregivers and facilitate their social integration.

Highlights: • A polygeneration system for a residential house is presented. • Hybrid photovoltaic/thermal collectors are used, coupled with a solar-assisted heat pump. • An optimization has been performed. • The system is profitable even in the absence of incentives. • A simple pay-back period of about 5 year is achieved. - Abstract: In the paper, a model for the simulation and the optimization of a novel solar trigeneration system is presented. The plant simulation model is designed to supply electricity, space heating or cooling and domestic hot water for a small residential building. The system is based on a solar field equipped with flat-plate photovoltaic/thermal collectors, coupled with a water-to-water electric heat pump/chiller. The electrical energy produced by the hybrid collectors is entirely supplied to the building. During the winter, the thermal energy available from the solar field is used as a heat source for the evaporator of the heat pump and/or to produce domestic hot water. During the summer, the heat pump operates in cooling mode, coupled with a closed circuit cooling tower, providing space cooling for the building, and the hot water produced by the collectors is only used to produce domestic hot water. For such a system, a dynamic simulation model was developed in TRNSYS environment, paying special attention to the dynamic simulation of the building, too. The system was analyzed from an energy and economic point of view, considering different time bases. In order to minimize the pay-back period, an optimum set of the main design/control parameters was obtained by means of a sensitivity analysis. Simultaneously, a computer-based Design of Experiment procedure was implemented, aiming at calculating the optimal set of design parameters, using both energy and economic objective functions. The results showed that thermal and electrical efficiencies are above 40% and 10%, respectively. The coefficient of performance of the reversible heat

2012-03-01

Hand-assisted laparoscopic liver surgery, a newly developed technique based on an innovative concept, has proved useful and safe for a variety of less invasive hepatectomies. Radiofrequency-assisted hepatic resection has been reported to be safe, associated with minimal morbidity and mortality and decreased intraoperative blood loss and transfusion requirements. We describe how we perform hand-assisted laparoscopic radiofrequency-assisted hepatic resection using a bipolar radiofrequency device. The use of the hand port has allowed the surgeon to use his hand in direct liver manipulation, mobilization, and retraction. It was also useful for tactile tumour localization. Radiofrequency-assisted hepatic parenchymal transection was performed on 15 patients using a bipolar device (Habib 4X) with minimal blood loss (74 ml), and very decent operative and resection times (92 min, 33 min respectively). This combined procedure offers a safe, effective and rapid liver resection technique. This might encourage surgeons to perform a minimally invasive approach for liver resection more frequently.

2018-02-01

The paper focuses on the issue of drinking water supply without use of any disinfectants. Before the public water supply network operator begins to consider switching to operation without use of chemical disinfection, initial assessment should be made, whether or not the water supply system in question is suitable for this type of operation. The assessment is performed by applying the decision algorithm. The initial assessment is followed by another decision algorithm which serves for managing and controlling the process of switching to drinking water supply without use of a disinfectant. The paper also summarizes previous experience and knowledge of this way operated public water supply systems in the Czech Republic.

Domestic rainwater harvesting to improve water supply in rural South Africa

Science.gov (United States)

Mwenge Kahinda, Jean-marc; Taigbenu, Akpofure E.; Boroto, Jean R.

Halving the proportion of people without sustainable access to safe drinking water and basic sanitation, is one of the targets of the 7th Millennium Development Goals (MDGs). In South Africa, with its mix of developed and developing regions, 9.7 million (20%) of the people do not have access to adequate water supply and 16 million (33%) lack proper sanitation services. Domestic Rainwater Harvesting (DRWH), which provides water directly to households enables a number of small-scale productive activities, has the potential to supply water even in rural and peri-urban areas that conventional technologies cannot supply. As part of the effort to achieve the MDGs, the South African government has committed itself to provide financial assistance to poor households for the capital cost of rainwater storage tanks and related works in the rural areas. Despite this financial assistance, the legal status of DRWH remains unclear and DRWH is in fact illegal by strict application of the water legislations. Beyond the cost of installation, maintenance and proper use of the DRWH system to ensure its sustainability, there is risk of waterborne diseases. This paper explores challenges to sustainable implementation of DRWH and proposes some interventions which the South African government could implement to overcome them.

Computer utilization for the solution of gas supply problems

Raleigh, J T; Brady, J R

1968-01-01

The computer programs in this paper have proven to be useful tools in the solution of gas supply problems. Some of the management type of applications are: (1) long range planning projects; (2) comparison of various proposed gas purchase contracts; (3) to assist with budget and operational planning; (4) to assist in making cost-of-servic and rate predictions; (5) to investigate the feasibility of processing plants at any point on the system; and (6) to assist dispatching in its daily operation for cost and quality control. Competition, not only from the gas industry, but also from other forms of energy, makes it imperative that quantitative and economic information with regard to that marketable resource be available under a variety of assumptions and alternatives. This information can best be made available in a timely manner by the use of the computer.

2005-01-01

Environmentally assisted cracking (EAC) of carbon and low-alloy steels has been identified as a possible degradation mechanism for pressure vessels and piping in nuclear power plants. Selected aspects of research and service experience with cracking of these materials in high-temperature water are reviewed, with special emphasis on the primary pressure boundary in boiling water reactors. The main factors controlling EAC susceptibility under reactor conditions are discussed with regard to both crack initiation and crack growth. The adequacy and conservatism of the relevant engineering criteria for component design and disposition of detected or postulated flaws are evaluated in the context of recent research results, e.g., on the effects of so-called ''ripple loading'' or of water chemistry transients. Finally, the relevant operating experience over the last 30 years is briefly summarized and compared with the background knowledge which has been accumulated in more recent laboratory experiments. Some of the insights gained in this work may also be of value in improving understanding and prediction of the EAC behavior of carbon and low-alloy steels in certain fossil plant components, if appropriate allowances are made for differences in temperature and water chemistry.

Controversy surrounding disclosure among the recipients of assisted reproductive donation procedures is escalating worldwide, but little research has been conducted in this topic. The purpose of this qualitative study was to explore the experiences of infertile couples undergoing assisted reproductive donation procedures. In this exploratory qualitative study, 32 patients (nine couples and 14 women) who were candidates to use donor eggs, donor embryos or surrogacy, and 5 members of infertility treatment team including gynaecologists, midwives and psychologist (total 37) were purposively selected from the Montaserieh Infertility Research Centre at Mashhad, Iran in 2012 and interviewed using a semi-structured in-depth method. Data were analysed using conventional qualitative content analysis with MAXqda software. One overarching theme, entitled 'experiencing uncertainty surrounding the disclosure to others' was identified from the data. This theme contained two subthemes including 'Couples' decisions to not disclose to others' and 'Couples' decisions to disclose to others'. Five categories formed the first subtheme, and the second subtheme emerged from four categories which are discussed in this paper. The main reason for secrecy was concern over societal negative views about assisted reproductive donation procedures. This worry deprived the couples from support from family and friends and as a result requires them to tolerate psychological pressure when using such procedures.

The overvoltage protection module for the power supply system for the pixel detector at Belle II experiment at KEK

International Nuclear Information System (INIS)

Kapusta, P.; Kisielewski, B.

2015-01-01

In this paper the overvoltage protection modules (OVP) for the power supply (PS) system of the Belle II pixel detector (PXD) are described. The aim of the OVP is to protect the detector and associated electronics against overvoltage conditions. Most critical in the system are voltages supplying the front-end ASICs. The PXD detector consists of the DEPFET sensor modules with integrated chips like the Drain Current Digitizer, the Switcher and the Data Handling Processor. These chips, implemented in modern sub-micron technologies, are quite vulnerable to variations in the supply voltages. The PXD will be placed in the Belle II experiment as close as possible to the interaction point, where access during experiment is very limited or even impossible, thus the PS and OVP systems exploit the remote-sensing method. Overvoltage conditions are due to failures of the PS itself, wrong setting of the output voltages or transient voltages coming out of hard noisy environment of the experiment. The OVP modules are parts of the PS modules. For powering the PXD 40 PS modules are placed 15 m outside the Belle II spectrometer. Each one is equipped with the OVP board. All voltages (22) are grouped in 4 domains: Analog, Digital, Steering and Gate which have independent grounds. The OVP boards are designed from integrated circuits from Linear Technology. All configurations were simulated with the Spice program. The control electronics is designed in a Xilinx CPLD. Two types of integrated circuits were used. LT4356 surge stopper protects loads from high voltage transients. The output voltages are limited to a safe value and also protect loads against over current faults. For less critical voltages, the LTC2912 voltage monitors are used that detect under-voltage and overvoltage events. It has to be noted that the OVP system is working independently of any other protection of the PS system, which increases its overall reliability. (authors)

Surgical complications are a major disincentive to pancreas transplantation, despite the undisputed benefits of restored insulin independence. The da Vinci surgical system, a computer-assisted electromechanical device, provides the unique opportunity to test whether laparoscopy can reduce the morbidity of pancreas transplantation. Pancreas transplantation was performed by robot-assisted laparoscopy in three patients. The first patient received a pancreas after kidney transplant, the second a simultaneous pancreas kidney transplantation, and the third a pancreas transplant alone. Operations were carried out through an 11-mm optic port, two 8-mm operative ports, and a 7-cm midline incision. The latter was used to introduce the grafts, enable vascular cross-clamping, and create exocrine drainage into the jejunum. The two solitary pancreas transplants required an operating time of 3 and 5 hr, respectively; the simultaneous pancreas kidney transplantation took 8 hr. Mean warm ischemia time of the pancreas graft was 34 min. All pancreatic transplants functioned immediately, and all recipients became insulin independent. The kidney graft, revascularized after 35 min of warm ischemia, also functioned immediately. No patient had complications during or after surgery. At the longer follow-up of 10, 8, and 6 months, respectively, all recipients are alive with normal graft function. We have shown the feasibility of laparoscopic robot-assisted solitary pancreas and simultaneous pancreas and kidney transplantation. If the safety and feasibility of this procedure can be confirmed by larger series, laparoscopic robot-assisted pancreas transplantation could become a new option for diabetic patients needing beta-cell replacement.

One of the 24 Accel dc Power Supplies (ADCPS) originally intended for the Mirror Fusion Test Facility (MFTF-B) Neutral Beam Power Supply (NBPS) System has been converted to provide negative polarity output at 90 kV with a load current of 64 A dc. The load duty cycle is a pulse of 30-seconds duration with a pulse repetition period of five minutes. A new control system has been built which will serve as a prototype for the MFTF-B ADCPS controls, and a test setup was built which will be used to test the ADCPS. The Electron Cyclotron Resonance Heating (ECRH) dc Power Supply (DCPS) has been tested under both no-load and dummy-load conditions, under remote control, without notable problems. Test results indicate that the power supply should be reliable and safe to operate, and will meet the load duty requirements

Computer-controlled systems are commonly used in clinical trials to control dispensing and manage site inventories of trial supplies. Typically such systems are used with an interactive telephone or web system that provide an interface with the study site. Realizing the maximum savings in medication associated with this approach has, in the past, been problematic as it has been difficult to fully estimate medication requirements due to the complexities of these algorithms and the inherent variation in the clinical trial recruitment process. We describe the traditional and automated methods of supplying sites. We detail a simulation approach that models the automated system. We design a number of simulation experiments using this model to investigate the supply strategy properties that influence medication overage and other strategy performance metrics. The computer-controlled medication system gave superior performance to the traditional method. In one example, a 75% overage of wasted medication in the traditional system was associated with higher supply failure than an automated system strategy with an overage of 47%. In a further example, we demonstrate that the impact of using a country stratified as opposed to site stratified scheme affects the number of deliveries and probability of supply failures more than the amount of drug wasted with respective increases of 20, 2300 and 4%. Medication savings with automated systems are particularly significant in repeat dispensing designs. We show that the number of packs required can fall by as much as 50% if one uses a predictive medication algorithm. We conclude that a computer-controlled supply chain enables medication savings to be realized and that it is possible to quantify the distribution of these savings using a simulation model. The simulation model can be used to optimize the prestudy medication supply strategy and for midstudy monitoring using real-time data contained in the study database.

System for selecting a postponement strategy portfolio for supply chains

Directory of Open Access Journals (Sweden)

Luiz Eduardo Simão

2015-03-01

Full Text Available The stagnation of the economy has increased competition and uncertainty in the industrial sector. Trends such as the increase in the proliferation of the variety of products and the requirement for customization of products has contributed to difficulties in forecasting demand, due to increased uncertainty of demand for final products. In this new competitive environment, it is no longer possible to use the traditional “one size fits all” supply chain process, with unique policies for all products because this practice can lead to significant profitability losses due to the increase in stock levels and lost sales. However, research on supply chains has given relatively little attention to the need to use different, segmented supply chain strategies as well as to develop and manage these multiple supply chains strategies simultaneously. Thus, this paper aims to present an approach for selecting a portfolio of postponement strategies based on segmentation of supply chain, based on analysis of the demand profile (volume-variety analysis and a tool to assist in the selection of postponement strategies driven by the customer-product sector and their respective propositions of value.

The Molybdenum-99/Technetium-99m ( 99 Mo/ 99m Tc) supply disruptions occurred in the recent years prompted the European Commission and industry to establish in 2012 a European Observatory on the Supply of Medical Radioisotopes, aimed at bringing together all relevant information to the decision makers in the European Union (EU) institutions and national governments in order to assist them in defining strategies as well as policies for their implementation. The Observatory follows the Organisation for Economic Co-operation and Development/Nuclear Energy Agency-OECD/NEA principles established by the High Level Group on the Security of Supply of Medical Radioisotopes (HLG-MR), of which the European Commission is a Member, and focuses on the specificities of their implementation in the EU, recognizing at the same time that the supply is of a global nature and requires broader international cooperation. The Observatory has four general strategic objectives: to support a secure 99 Mo/ 99m Tc supply across the European Union, ensure that the issue of 99 Mo/ 99m Tc supply is given high political visibility, encourage the creation of a sustainable economic structure of the supply chain and establish periodic reviews of the supply capacities and demand.

The Colorado Learning Assistant (LA) Program serves as a content-specific supplement to standard teacher preparation programs. In addition to transforming undergraduate STEM courses, it recruits and prepares math and science majors for teaching careers by involving university STEM faculty. The research reported here compares the teaching practices of in-service teachers who participated in the LA experience as undergraduates to a comparison group of teachers who did not participate in the LA program as undergraduates but were certified to teach through the same program. We report on teachers' views of assessments and differences in their teaching practices. This analysis is based on interviews with approximately 30 teachers and observations of their classrooms throughout their induction years of teaching. This work considers how the LA program may help improve current teacher preparation models.

Linking consumer energy efficiency with security of supply

2007-01-01

Most modern energy policies seek to achieve systematic ongoing incremental increases in consumer energy efficiency, since this contributes to improved security of supply, favourable environmental outcomes and increased economic efficiency. Yet realised levels of efficiency are typically well below the most cost-effective equilibrium due to variety of behavioural and organisational barriers, which are often linked to information constraints. In addition efficient users are normally unrewarded for collective benefits to system security and to the environment, thus reducing the incentives for energy consumers to invest in efficiency improvements. This paper examines the dichotomies and symmetries between supply- and demand-side solutions to energy security concerns and reviews opportunities to overcome barriers to improved consumer efficiency. A security market is identified as a mechanism to promote both demand- and supply-side investments that support electricity system security. Such a market would assist in setting the optimal quantity of reserves while achieving an efficient balance between supply- and demand-side initiatives. It would also help to smooth overall investment throughout the energy system by encouraging incremental approaches, such as distributed generation and demand-side alternatives where they provide competitive value. Although the discussion is applicable to energy systems in general, it focuses primarily on electricity in New Zealand

Combined Use of Mathematical Optimization and Design of Experiments for the Maximization of Profit in a Four-Echelon Supply Chain

Daniel Arturo Olivares Vera

2018-01-01

Full Text Available This paper develops a location-allocation model to optimize a four-echelon supply chain network, addressing manufacturing and distribution centers location, supplier selection and flow allocation for raw materials from suppliers to manufacturers, and finished products for end customers, while searching for system profit maximization. A fractional-factorial design of experiments is performed to analyze the effects of capacity, quality, delivery time, and interest rate on profit and system performance. The model is formulated as a mixed-integer linear programming problem and solved by using well-known commercial software. The usage of factorial experiments combined with mathematical optimization is a novel approach to address supply chain network design problems. The application of the proposed model to a case study shows that this combination of techniques yields satisfying results in terms of both its behavior and the obtained managerial insights. An ANOVA analysis is executed to quantify the effects of each factor and their interactions. In the analyzed case study, the transportation cost is the most relevant cost component, and the most relevant opportunity for profit improvement is found in the factor of quality. The proposed combination of methods can be adapted to different problems and industries.

Chen, T. R.; Lee, Y. L.; Liu, H. T.; Chen, S. M.; Chang, H. Z.

2017-11-01

In this study, a contactless power supply for the ultrasonic motor on the spindle is proposed. The proposed power supply is composed of a series-parallel resonant circuit and a cylindrical contactless transformer. Based on the study and rotation experiments, it can be seen that the proposed power supply can both provide a stable ac power with 25 kHz / 70 V to the ultrasonic motor. When the output power is 250 W, the efficiency of the proposed supply is 89.8 % in respectively rotation tests. When the output power is more than 150 W, the efficiency of the proposed supply is higher than 80 % within the rated output power range.

Full Text Available CONTEXT AND PURPOSE: Partial nephrectomy has become the standard of care for renal tumors less than 4 cm in diameter. Controversy still exists, however, regarding the best surgical approach, especially when minimally invasive techniques are taken into account. Robotic-assisted laparoscopic partial nephrectomy (RALPN has emerged as a promising technique that helps surgeons achieve the standards of open partial nephrectomy care while offering a minimally invasive approach. The objective of the present study was to describe our initial experience with robotic-assisted laparoscopic partial nephrectomy and extensively review the pertinent literature. MATERIALS AND METHODS: Between August 2009 and February 2010, eight consecutive selected patients with contrast enhancing renal masses observed by CT were submitted to RALPN in a private institution. In addition, we collected information on the patients' demographics, preoperative tumor characteristics and detailed operative, postoperative and pathological data. In addition, a PubMed search was performed to provide an extensive review of the robotic-assisted laparoscopic partial nephrectomy literature. RESULTS: Seven patients had RALPN on the left or right sides with no intraoperative complications. One patient was electively converted to a robotic-assisted radical nephrectomy. The operative time ranged from 120 to 300 min, estimated blood loss (EBL ranged from 75 to 400 mL and, in five cases, the warm ischemia time (WIT ranged from 18 to 32 min. Two patients did not require any clamping. Overall, no transfusions were necessary, and there were no intraoperative complications or adverse postoperative clinical events. All margins were negative, and all patients were disease-free at the 6-month follow-up. CONCLUSIONS: Robotic-assisted laparoscopic partial nephrectomy is a feasible and safe approach to small renal cortical masses.Further prospective studies are needed to compare open partial nephrectomy with

Temperature Stabilized Characterization of High Voltage Power Supplies

Krarup, Ole

2017-01-01

High precision measurements of the masses of nuclear ions in the ISOLTRAP experiment relies on an MR-ToF. A major source of noise and drift is the instability of the high voltage power supplies employed. Electrical noise and temperature changes can broaden peaks in time-of-flight spectra and shift the position of peaks between runs. In this report we investigate how the noise and drift of high-voltage power supplies can be characterized. Results indicate that analog power supplies generally have better relative stability than digitally controlled ones, and that the high temperature coefficients of all power supplies merit efforts to stabilize them.

Bohm, Eric R; Dunbar, Michael; Pitman, David; Rhule, Chris; Araneta, Jose

Recent increases in orthopedic surgical services in Canada have added further demand to an already stretched orthopedic workforce. Various initiatives have been undertaken across Canada to meet this demand. One successful model has been the use of physician assistants (PAs) within the Winnipeg Regional Health Authority (WRHA). This study documents the effect of PAs working in an arthroplasty practice from the perspective of patients and health care providers. We also describe the costs, time savings for surgeons and the effects on surgical throughput and waiting times. We calculated time savings by the use of a daily diary kept by the PAs. Surgeons', residents', nurses' and patients' opinions about PAs were recorded by use of a self administered questionnaire. We calculated costs using forgone general practitioner (GP) surgical assist fees and salary costs for PAs. We obtained information about surgical throughput and wait times from the WRHA waitlist database. In this study, PAs "saved" their supervising physician about 204 hours per year; this time can be used for other clinical, administrative or research duties. Physician assistants are regarded as important members of the health care team by surgeons, nurses, orthopedic residents and patients. When we compared the billing costs with those that would have been generated by the use of GP surgical assists, PAs were essentially cost neutral. Furthermore, they potentially freed GPs from the operating room to spend more time delivering primary care. We found that use of the double operating room model facilitated by PAs increased the surgical throughput of primary hip and knee replacements by 42%, and median wait times decreased from 44 weeks to 30 weeks compared with the preceding year. Physician assistants integrate well into the care team and can increase surgical volumes to reduce wait times in a cost-effective manner.

2013-12-01

Full Text Available One of the main reasons for the difficulty in adopting an integrated method of calculation of logistics costs is still a lack of adequate information about costs. The management of the supply chain and identify its costs can provide information for their managers, with regard to decision making, generating competitive advantage. Some models of calculating logistics costs are proposed by Uelze (1974, Dias (1996, Goldratt (2002, Christopher (2007, Castiglioni (2009 and Borba & Gibbon (2009, with little disclosure of the results. In this context, this study aims to evaluate the costs of supplies, applying a measurement model of logistics costs. Methodologically, the study characterized as exploratory. The model applied pointed, in original condition, that about R$ 2.5 million were being applied in the process of management of supplies, with replacement costs and storage imbalance. Upgrading the company's data, it is possible obtain a 52% reduction in costs to replace and store supplies. Thus, the cost model applied to logistical supplies showed feasibility of implementation, as well as providing information to assist in management and decision-making in logistics supply.

Chemistry Graduate Teaching Assistants' Experiences in Academic Laboratories and Development of a Teaching Self-image

Science.gov (United States)

Gatlin, Todd Adam

Graduate teaching assistants (GTAs) play a prominent role in chemistry laboratory instruction at research based universities. They teach almost all undergraduate chemistry laboratory courses. However, their role in laboratory instruction has often been overlooked in educational research. Interest in chemistry GTAs has been placed on training and their perceived expectations, but less attention has been paid to their experiences or their potential benefits from teaching. This work was designed to investigate GTAs' experiences in and benefits from laboratory instructional environments. This dissertation includes three related studies on GTAs' experiences teaching in general chemistry laboratories. Qualitative methods were used for each study. First, phenomenological analysis was used to explore GTAs' experiences in an expository laboratory program. Post-teaching interviews were the primary data source. GTAs experiences were described in three dimensions: doing, knowing, and transferring. Gains available to GTAs revolved around general teaching skills. However, no gains specifically related to scientific development were found in this laboratory format. Case-study methods were used to explore and illustrate ways GTAs develop a GTA self-image---the way they see themselves as instructors. Two general chemistry laboratory programs that represent two very different instructional frameworks were chosen for the context of this study. The first program used a cooperative project-based approach. The second program used weekly, verification-type activities. End of the semester interviews were collected and served as the primary data source. A follow-up case study of a new cohort of GTAs in the cooperative problem-based laboratory was undertaken to investigate changes in GTAs' self-images over the course of one semester. Pre-semester and post-semester interviews served as the primary data source. Findings suggest that GTAs' construction of their self-image is shaped through the

Adequacy of supply standards for the electricity market: from obligations to informal market signals

The adequacy of supply standard is ultimately based on a loss of load probability in combination with assumptions about the extent to which the national system can count on assistance of adjoining electricity supply systems during times of shortages. It can be used to calculate the required generation capacity in an ex-ante market analysis using different future scenarios. This standard in combination with monitoring of (future) market developments on the basis of several market indicators, can give a signal to market participants with respect to the expected adequacy of supply in the longer term. Market participants are informed about the actual and expected future status of adequacy of supply in the market. It is, however, very important that the assessment and the resulting signal should not be used by the government to intervene in the market, but only to improve market transparency and assist producers, suppliers, and consumers in their decisions towards an effective and efficient response on long-term market developments. Specific policy measures based on the monitoring results could provoke strategic behaviour of market participants. The signalising standard might be a powerful instrument in helping to solve the generation adequacy problem. This solution can be seen as a compromise between options that fully rely on an optimal response by the free electricity market and options where governments take the full responsibility

Demand forecasting is one of the key activities in planning the freight flows in supply chains, and accordingly it is essential for planning and scheduling of logistic activities within observed supply chain. Accurate demand forecasting models directly influence the decrease of logistics costs, since they provide an assessment of customer demand. Customer demand is a key component for planning all logistic processes in supply chain, and therefore determining levels of customer demand is of great interest for supply chain managers. In this paper we deal with exactly this kind of problem, and we develop the seasonal Autoregressive IntegratedMoving Average (SARIMA) model for forecasting demand patterns of a major product of an observed beverage company. The model is easy to understand, flexible to use and appropriate for assisting the expert in decision making process about consumer demand in particular periods.

There is no doubt about the importance of North Sea oil to the energy supply of the European Community. One might however be used to it and forget about the nature and the size of its impact on our economies. Firstly, this paper intends to estimate this impact - past, present and future. Secondly, a more qualitative approach will explore possible consequences of the implementation of the internal market for North Sea oil. Thirdly, the assistance given by the Community to innovative technologies which enabled North Sea oil to contribute, under better economic conditions and within a safer environment, to our supply is recalled. And finally, some remarks on energy policy form an EC perspective, are offered. (author)

Since 2012 six AAL pilot regions were launched in Austria. The main goal of these pilot regions is to evaluate the impact of AAL technologies in daily use considering the entire value chain. Additionally, go-to market strategies for assistive technologies based on an involvement of all relevant stakeholders are developed. Within this paper an overview of the specific objectives, approaches and the status of all Austrian AAL pilot regions is given. Taking into account the different experiences of the different pilot regions, specific challenges in establishing, implementing and sustaining pilot region projects are discussed and lessons-learned are presented. Results show that a careful planning of all project phases taking into account available resources is crucial for the successful implementation of an AAL pilot region. In particular, this applies to all activities related to the active involvement of end-users.

In the Virtual Observatory (VO), software tools will perform the functions that have traditionally been performed by physical observatories and their instruments. These tools will not be adjuncts to VO functionality but will make up the very core of the VO. Consequently, the tradition of observatory and system independent tools serving a small user base is not valid for the VO. For the VO to succeed, we must improve software collaboration and code sharing between projects and groups. A significant goal of the Scientist's Expert Assistant (SEA) project has been promoting effective collaboration and code sharing among groups. During the past three years, the SEA project has been developing prototypes for new observation planning software tools and strategies. Initially funded by the Next Generation Space Telescope, parts of the SEA code have since been adopted by the Space Telescope Science Institute. SEA has also supplied code for the SIRTF (Space Infrared Telescope Facility) planning tools, and the JSky Open Source Java library. The potential benefits of sharing code are clear. The recipient gains functionality for considerably less cost. The provider gains additional developers working with their code. If enough users groups adopt a set of common code and tools, de facto standards can emerge (as demonstrated by the success of the FITS standard). Code sharing also raises a number of challenges related to the management of the code. In this talk, we will review our experiences with SEA--both successes and failures, and offer some lessons learned that might promote further successes in collaboration and re-use.

Quantitative model of New Zealand's energy supply industry

1977-10-15

A mathematical model is presented to assist in an analysis of energy policy options available. The model is based on an engineering orientated description of New Zealand's energy supply and distribution system. The system is cast as a linear program, in which energy demand is satisfied at least cost. The capacities and operating modes of process plant (such as power stations, oil refinery units, and LP-gas extraction plants) are determined by the model, as well as the optimal mix of fuels supplied to the final consumers. Policy analysis with the model enables a wide ranging assessment of the alternatives and uncertainties within a consistent quantitative framework. It is intended that the model be used as a tool to investigate the relative effects of various policy options, rather than to present a definitive plan for satisfying the nation's energy requirements.

For over 20 years complex, in-reactor experiments have been performed at Argonne National Laboratory (ANL) to investigate the performance of nuclear reactor fuel and to support the development of large computer codes that address questions of reactor safety in full-scale plants. Not only are computer codes an important end-product of the research, but computer analysis is also involved intimately at most stages of experiment planning, data reduction, and evaluation. For instance, many experiments are of sufficiently long duration or, if they are of brief duration, occur in such a purposeful sequence that need for speedy availability of on-line data is paramount. This is made possible most efficiently by computer assisted displays and evaluation. A purposeful linking of main-frame, mini, and micro computers has been effected over the past eight years which greatly enhances the speed with which experimental data are reduced to useful forms and applied to the relevant technological issues. This greater efficiency in data management led also to improvements in the planning and execution of subsequent experiments. Raw data from experiments performed at INEL is stored directly on disk and tape with the aid of minicomputers. Either during or shortly after an experiment, data may be transferred, via a direct link, to the Illinois offices of ANL where the data base is stored on a minicomputer system. This Idaho-to-Illinois link has both enhanced experiment performance and allowed rapid dissemination of results

Production, partitioning and stoichiometry of organic matter under variable nutrient supply during mesocosm experiments in the tropical Pacific and Atlantic Ocean

Directory of Open Access Journals (Sweden)

J. M. S. Franz

2012-11-01

Full Text Available Oxygen-deficient waters in the ocean, generally referred to as oxygen minimum zones (OMZ, are expected to expand as a consequence of global climate change. Poor oxygenation is promoting microbial loss of inorganic nitrogen (N and increasing release of sediment-bound phosphate (P into the water column. These intermediate water masses, nutrient-loaded but with an N deficit relative to the canonical N:P Redfield ratio of 16:1, are transported via coastal upwelling into the euphotic zone. To test the impact of nutrient supply and nutrient stoichiometry on production, partitioning and elemental composition of dissolved (DOC, DON, DOP and particulate (POC, PON, POP organic matter, three nutrient enrichment experiments were conducted with natural microbial communities in shipboard mesocosms, during research cruises in the tropical waters of the southeast Pacific and the northeast Atlantic. Maximum accumulation of POC and PON was observed under high N supply conditions, indicating that primary production was controlled by N availability. The stoichiometry of microbial biomass was unaffected by nutrient N:P supply during exponential growth under nutrient saturation, while it was highly variable under conditions of nutrient limitation and closely correlated to the N:P supply ratio, although PON:POP of accumulated biomass generally exceeded the supply ratio. Microbial N:P composition was constrained by a general lower limit of 5:1. Channelling of assimilated P into DOP appears to be the mechanism responsible for the consistent offset of cellular stoichiometry relative to inorganic nutrient supply and nutrient drawdown, as DOP build-up was observed to intensify under decreasing N:P supply. Low nutrient N:P conditions in coastal upwelling areas overlying O₂-deficient waters seem to represent a net source for DOP, which may stimulate growth of diazotrophic phytoplankton. These results demonstrate that microbial nutrient assimilation and

A quantitative metric to identify critical elements within seafood supply networks.

Full Text Available A theoretical basis is required for comparing key features and critical elements in wild fisheries and aquaculture supply chains under a changing climate. Here we develop a new quantitative metric that is analogous to indices used to analyse food-webs and identify key species. The Supply Chain Index (SCI identifies critical elements as those elements with large throughput rates, as well as greater connectivity. The sum of the scores for a supply chain provides a single metric that roughly captures both the resilience and connectedness of a supply chain. Standardised scores can facilitate cross-comparisons both under current conditions as well as under a changing climate. Identification of key elements along the supply chain may assist in informing adaptation strategies to reduce anticipated future risks posed by climate change. The SCI also provides information on the relative stability of different supply chains based on whether there is a fairly even spread in the individual scores of the top few key elements, compared with a more critical dependence on a few key individual supply chain elements. We use as a case study the Australian southern rock lobster Jasus edwardsii fishery, which is challenged by a number of climate change drivers such as impacts on recruitment and growth due to changes in large-scale and local oceanographic features. The SCI identifies airports, processors and Chinese consumers as the key elements in the lobster supply chain that merit attention to enhance stability and potentially enable growth. We also apply the index to an additional four real-world Australian commercial fishery and two aquaculture industry supply chains to highlight the utility of a systematic method for describing supply chains. Overall, our simple methodological approach to empirically-based supply chain research provides an objective method for comparing the resilience of supply chains and highlighting components that may be critical.

A theoretical basis is required for comparing key features and critical elements in wild fisheries and aquaculture supply chains under a changing climate. Here we develop a new quantitative metric that is analogous to indices used to analyse food-webs and identify key species. The Supply Chain Index (SCI) identifies critical elements as those elements with large throughput rates, as well as greater connectivity. The sum of the scores for a supply chain provides a single metric that roughly captures both the resilience and connectedness of a supply chain. Standardised scores can facilitate cross-comparisons both under current conditions as well as under a changing climate. Identification of key elements along the supply chain may assist in informing adaptation strategies to reduce anticipated future risks posed by climate change. The SCI also provides information on the relative stability of different supply chains based on whether there is a fairly even spread in the individual scores of the top few key elements, compared with a more critical dependence on a few key individual supply chain elements. We use as a case study the Australian southern rock lobster Jasus edwardsii fishery, which is challenged by a number of climate change drivers such as impacts on recruitment and growth due to changes in large-scale and local oceanographic features. The SCI identifies airports, processors and Chinese consumers as the key elements in the lobster supply chain that merit attention to enhance stability and potentially enable growth. We also apply the index to an additional four real-world Australian commercial fishery and two aquaculture industry supply chains to highlight the utility of a systematic method for describing supply chains. Overall, our simple methodological approach to empirically-based supply chain research provides an objective method for comparing the resilience of supply chains and highlighting components that may be critical.

Full Text Available Abstract On the world stage, Brazil is the third largest world fruit producer. However, purchasing fruit companies are suffering from the effects of fluctuations in production and demand, inefficiency in production and information trade, lack of understanding of the dynamics of supply and reduction in profitability for all members of the fruit production chain. The supply chain management has been touted as one of the ways to reduce this volatility and improve outcomes for all involved with the supply chain. However, results of recent researches do not relate it directly to the fruit industry. To solve this problem, the present research aimed to analyze the planning and management of the supply chain of a fruit purchasing company and identify contributions and improvements to the theories and methods related to supply chain management to propose a method for planning and management the supply chain of fruit purchasing companies. It was conducted a case study from a mango fruit purchasing company using interviews with industry experts to assess the applicability, functionality and usefulness from the managerial point of view of the proposed method. Data analysis was done through the cross analysis of the methods of the supply chain management and the description of the case. The results of the study allowed the development of a method for planning and management the supply chain of fruit purchasing company. With the proposition of this method is expected to contribute with a sequence of steps to assist in planning and management of supply chain managers and specialists from a fruit purchasing company.

The aim of this report is to describe our surgical technique of totally intracorporeal robotic assisted radical cystectomy (RARC) with neobladder formation. Between December 2003 and March 2013, a total of 147 patients (118 male, 29 female) underwent totally intracorporeal RARC for urinary bladder cancer. We also performed a systematic search of Medline, Embase and PubMed databases using the terms RARC, robotic cystectomy, robot-assisted, totally intracorporeal RARC, intracorporeal neobladder, intracorporeal urinary diversion, oncological outcomes, functional outcomes, and complication rates. The mean age of our patients was 64 years (range 37-87). On surgical pathology 47% had pT1 or less disease, 27% had pT2, 16% had pT3 and 10% had pT4. The mean number of lymph nodes removed was 21 (range 0-60). 24% of patients had lymph node positive dAQ1isease. Positive surgical margins occurred in 6 cases (4%). Mean follow-up was 31 months (range 4-115 months). Two patients (1.4%) died within 90 days of their operation. Using Kaplan-Meier analysis, overall survival and cancer specific survival at 60 months was 68% and 69.6%, respectively. 80 patients (54%) received a continent diversion with totally intracorporeal neobladder formation. In the neobladder subgroup median total operating time was 420 minutes (range 265-760). Daytime continence and satisfactory sexual function or potency at 12 months ranged between 70-90% in both men and women. Our experience with totally intracorporeal RARC demonstrates acceptable oncological and functional outcomes that suggest this is a viable alternative to open radical cystectomy.

Reducing greenhouse gas emissions through operations and supply chain management

International Nuclear Information System (INIS)

Plambeck, Erica L.

2012-01-01

The experiences of the largest corporation in the world and those of a start-up company show how companies can profitably reduce greenhouse gas emissions in their supply chains. The operations management literature suggests additional opportunities to profitably reduce emissions in existing supply chains, and provides guidance for expanding the capacity of new “zero emission” supply chains. The potential for companies to profitably reduce emissions is substantial but (without effective climate policy) likely insufficient to avert dangerous climate change. - Highlights: ► Describes how firms are profitably reducing greenhouse gas emissions in their supply chains ► Highlights academic literature relevant to supply chain emission reduction

Defining the Synthetic Biology Supply Chain.

Frazar, Sarah L; Hund, Gretchen E; Bonheyo, George T; Diggans, James; Bartholomew, Rachel A; Gehrig, Lindsey; Greaves, Mark

Several recent articles have described risks posed by synthetic biology and spurred vigorous discussion in the scientific, commercial, and government communities about how to best detect, prevent, regulate, and respond to these risks. The Pacific Northwest National Laboratory's (PNNL) deep experience working with dual-use technologies for the nuclear industry has shown that analysis of supply chains can reveal security vulnerabilities and ways to mitigate security risk without hindering beneficial research and commerce. In this article, a team of experts in synthetic biology, data analytics, and national security describe the overall supply chain surrounding synthetic biology to illustrate new insights about the effectiveness of current regulations, the possible need for different screening approaches, and new technical solutions that could help identify or mitigate risks in the synthetic biology supply chain.

Experimental Investigation on the Material Removal of the Ultrasonic Vibration Assisted Abrasive Water Jet Machining Ceramics

Directory of Open Access Journals (Sweden)

Tao Wang

2017-01-01

Full Text Available The ultrasonic vibration activated in the abrasive water jet nozzle is used to enhance the capability of the abrasive water jet machinery. The experiment devices of the ultrasonic vibration assisted abrasive water jet are established; they are composed of the ultrasonic vibration producing device, the abrasive supplying device, the abrasive water jet nozzle, the water jet intensifier pump, and so on. And the effect of process parameters such as the vibration amplitude, the system working pressure, the stand-off, and the abrasive diameter on the ceramics material removal is studied. The experimental result indicates that the depth and the volume removal are increased when the ultrasonic vibration is added on abrasive water jet. With the increase of vibration amplitude, the depth and the volume of material removal are also increased. The other parameters of the ultrasonic vibration assisted abrasive water jet also have an important role in the improvement of ceramic material erosion efficiency.

Understanding Supplier Resistance - Overcoming Obstacles to Supply Innovation

Directory of Open Access Journals (Sweden)

New Steve

2014-11-01

Full Text Available This paper explores an important but unexplored theme in the development of 'total quality' relationships in the supply chain: why suppliers may exhibit resistance to quality initiatives, and why what seems to customers as cooperation can appear as unwelcome interference or even exploitation to suppliers. This is a question of great relevance to all those seeking to understand current business practice, and also to those seeking to bring about practical improvements in supply chain quality. Too much of the supply chain and quality literature assumes the issue of supplier's compliance with customer initiatives is unproblematic (unable to understand this sentence; experience suggests it is one of the major obstacles in developing the quality-oriented, integrated supply chain.

2006-01-01

For an employee with a disability, reasonable accommodation can make the difference in finding work, maintaining employment, and succeeding on the job. Today, employers and employees alike are more aware that appropriate accommodation, including workplace personal assistance services (PAS) as well as assistive technology, improves an employee's ability to succeed. While assistive technology is in widespread use as an accommodation, workplace personal assistance is less understood. The goal of the study was to learn more about how workplace PAS and AT are arranged for in the workplace, and the issues that arise. Structured phone interviews were conducted with 20 workplace PAS users, 21 employers familiar with workplace PAS, and 19 employment organizations. Interview transcripts are the basis for the qualitative analysis of findings. Requirements for personal assistance accommodations focus on task-related needs. Personal care needs at work are not included in the Americans with Disabilities act but may be needed by the employee. Employers and PAS users have developed many creative ways to address PAS need. Organizations can construct an approach that fits the needs, abilities, and constraints of each organization. The interview respondents have identified a number of practices that are succeeding, including establishment of policies for arranging for PAS; centralization of accommodation budgets to remove work unit disincentives; and providing a shared personal assistant for interpreting or for task-related and personal care tasks. A number of important research questions remain. What is the extent of the need for PAS in the workplace? Will an expanded PAS supply increase the employment opportunities for people with disabilities? Will better models of workplace PAS be adopted by employers?

Science.gov (United States)

Gyllensten, Kristina; Andersson, Gunnar; Muller, Helena

2017-01-01

There is a shortage of registered nurses in the European Union (EU), and job dissatisfaction and perceived high work-family conflict have been identified as causes of nursing staff turnover. Reducing work hours is an organisational intervention that could have a positive effect on nurses' and assistant nurses' job satisfaction, work-life balance, and willingness to stay in the job. An orthopaedic surgery department at a large hospital in Sweden introduced reduced work hours for nurses and assistant nurses in order to improve the working situation. The aim of the study was to investigate the experiences of reduced work hours and no lunch breaks among nurses and assistant nurses at an orthopaedic surgery department at a hospital in Sweden, with a particular focus on recovery and psychosocial working environment. A qualitative design was used in the study. Eleven nurses and assistant nurses working at the particular orthopaedic department took part in the study, and semi-structured interviews were used to collect data. The interviews were analysed by interpretative phenomenological analysis. Four main themes were developed in the analysis of the data: A more sustainable working situation, Improved work-life balance, Consequences of being part of a project, and Improved quality of care. Each theme consisted of subthemes. Overall, reduced work hours appeared to have many, mainly positive, effects for the participants in both work and home life.

2018-01-01

This paper identifies several sources of risks in DKI Jakarta rice supply chain that through Cipinang Primary Rice Market (CPRM). Secondary data from several sources were collected and analysed using pareto chart and time series analysis. Based on the pareto analysis, it was known that there was a change in the order of suppliers whereas in 2011, 80% of the supply came only from Cirebon, Karawang and Bandung (West Java Province). While in 2015 the main source of supply changed to Cirebon, Central Java and Karawang. Linear trend equation using decomposition model for Cirebon and Karawang showed trend of decreasing monthly supply while Central Java had a positive trend. Harvest area of wetland paddy in Cirebon and Karawang showed a negative trend in the last 6 years. The data also showed that West Java Province was the province with the largest rice crop area affected by plant organism attack and drought disaster in 2015. DKI Jakarta had several potential supply chain risks from rice supply, drought risk and pests risk where the province of West Java, which previously could become a major supplier began to require supply assistance from other provinces, especially Central Java.

Challenges in setting up a potable water supply system in a United Nations peacekeeping mission: the South Sudan experience.

Science.gov (United States)

Hazra, Aniruddha

2013-01-01

A United Nations peacekeeping contingent was deployed in the conflict affected areas of South Sudan with inadequate environmental sanitation, lack of clean drinking water and a heightened risk of water-borne diseases. In the immediate post-deployment phase, the contingent-owned water purification system was pressed into service. However, laboratory analyses of processed water revealed its unsuitability for human consumption. A systematic, sanitary survey was conducted to identify the shortcomings in the water supply system's ability to provide potable water. Under field conditions, the 'H2S method' was used to detect faecal contamination of drinking water. The raw water from the only available source, the White Nile River, was highly turbid and contaminated by intestinal and other pathogens due to an unprotected watershed. Water sterilizing powder was not readily available in the local area to replenish the existing stocks that had deteriorated during the long transit period from the troop contributing country. The water pipelines that had been laid along the ground, under water-logged conditions, were prone to microbial recontamination due to leakages in the network. The critical evaluation of the water supply system and necessary modifications in the purification process, based upon locally available options, yielded safe drinking water. Provision of safe drinking water in the mission area requires an in-depth analysis of prevailing conditions and appropriate planning in the pre-deployment phase. The chemicals for water purification should be procured through UN sources via a 'letter of assist' request from the troop contributor. Copyright © 2012 Elsevier GmbH. All rights reserved.

Thermally assisted mechanical dewatering (TAMD) is a new process for energy-efficient liquid/solids separation which enhances conventional-device efficiency. The main idea of this process is to supply a flow of heat in mechanical dewatering processes to favour the reduction of the liquid content. This is not a new idea but the proposed combination, especially the chosen operating conditions (T < 100 C and P < 3000 kPa) constitutes an original approach and a significant energy saving since the liquid is kept in liquid state. Response surface methodology was used to evaluate the effects of the processing parameters of TAMD on the final dry solids content, which is a fundamental dewatering parameter and an excellent indicator of the extent of TAMD. In this study, a two-factor central composite design was used to establish the optimum conditions for the TAMD of alfalfa biomass. Experiments were carried out on a laboratory compression cell. Experiments showed that the dewatering enhancement results only from thermal effects. With a moderate heat supply (T{sub piston} = 80 C), the dry solid content of the press cake can reach 66%, compared to 36% at ambient temperature. A significant regression model, describing changes on final dry solids content with respect to independent variables, was established with determination coefficient, R{sup 2}, greater than 88%. With an energy consumption of less than 150 kWh/m{sup 3}, the use of the TAMD process before a thermal drying process leads to an energy saving of at least 30% on the overall separation chain.

Integrating medical, assistive, and universally designed products and technologies: assistive technology device classification (ATDC).

Science.gov (United States)

Bauer, Stephen; Elsaesser, Linda-Jeanne

2012-09-01

ISO26000:2010 International Guidance Standard on Organizational Social Responsibility requires that effective organizational performance recognize social responsibility, including the rights of persons with disabilities (PWD), engage stakeholders and contribute to sustainable development. Millennium Development Goals 2010 notes that the most vulnerable people require special attention, while the World Report on Disability 2011 identifies improved data collection and removal of barriers to rehabilitation as the means to empower PWD. The Assistive Technology Device Classification (ATDC), Assistive Technology Service Method (ATSM) and Matching Person and Technology models provide an evidence-based, standardized, internationally comparable framework to improve data collection and rehabilitation interventions. The ATDC and ATSM encompass and support universal design (UD) principles, and use the language and concepts of the International Classification of Functioning, Disability and Health (ICF). Use ATDC and ICF concepts to differentiate medical, assistive and UD products and technology; relate technology "types" to markets and costs; and support provision of UD products and technologies as sustainable and socially responsible behavior. Supply-side and demand-side incentives are suggested to foster private sector development and commercialization of UD products and technologies. Health and health-related professionals should be knowledgeable of UD principles and interventions.

Tebbetts, J B

1998-10-01

Numerous complications and increased operating times were reported with ultrasonically assisted lipoplasty in the first several months after introduction of the technology in the United States. The purpose of this study was to review early reported complications and management regimens, evaluate possible causes of problems, and apply indications and techniques to attempt to minimize complications during an initial experience with this technique beginning in January of 1997. Seven specific indications and modifications of existing techniques were developed and applied to an initial clinical series of 70 consecutive patients who underwent ultrasound-assisted suction lipoplasty between January 10, 1997, and August 1, 1997. Follow-up ranged from 1 to 7 months. No perioperative or postoperative complication occurred in any patient in this series. In this series of ultrasound-assisted lipoplasty cases, application of the following criteria resulted in a series of 70 patients with 1 to 7-month follow-up without complications: (1) selecting patients with well localized fat deposits who were no more than 20 percent above their ideal body weight; (2) infusing a solution of Ringer's Lactate containing 1 cc of 1:1000 epinephrine per 1000 cc into the area of fat removal, stopping infusion when the tissues first become firm, not infusing to marked tissue turgor or skin induration; (3) restricting the level of energy application to a minimum of 1 cm from the undersurface of the dermis; (4) limiting ultrasonic energy application in each area to approximately 1 minute per estimated 100 cc of total aspirate in a wet to superwet environment; (5) not performing ultrasound-assisted lipoplasty in the same area as another procedure that could potentially compromise tissue vascularity; (6) using a Lysonix 2000 generator and 5-mm golf tee tip probe at a power setting of 8 to apply ultrasonic energy to the area of fat removal, ceasing energy application when tissue resistance to the passage

Coordination of Advertising Free Riding in Hybrid Channel Supply Chain

Directory of Open Access Journals (Sweden)

Jin Sha

2016-01-01

Full Text Available Advertising is a crucial tool for demand creation and market expansion; enterprises in supply chain use it widely to increase sales and improve profits. But the homogeneity of products sold in hybrid channel supply chain magnifies the positive externalities of advertising and leads to serious free-riding problem. To coordinate the supply chain effectively, firstly, this paper classifies hybrid channel supply chain based on the relationship between members and selects horizontally integrated, vertically integrated, and decentralized hybrid channel supply chains as research objects. Then, a demand function considering the common effect of price and advertising is proposed and coordination schemes for different types of supply chains are designed. Finally, a sensitivity analysis is performed to assess the impact of parameters on coordination using orthogonal experiment.

The aim of this study is to investigate the safety and effectiveness of Excimer laser-assisted lead extraction in Europe. The final European multi-centre study experience is presented. The Excimer is a cool cutting laser (50 degrees C) with a wavelength of 308 nm. The energy is emitted from the tip of a flexible sheath and is absorbed by proteins and lipids, 64% of the energy is absorbed at a tissue depth of 0.06 mm. The sheath is positioned over the lead, and the fibrosis surrounding the lead is vaporized while advancing the sheath without damaging other leads. From August 1996 to March 2001, 383 leads (170 atrial, 213 ventricular) in 292 patients (mean age 61.6 years, range 13-96) were extracted at 14 European centres. Mean implantation time was 74 months (3-358). Most frequent indications were pocket infection (26%), non-functional leads (21%), patient morbidity (21%), septicaemia or endocarditis (14%), erosion (5%), and lead interference (8%). Median extraction time was 15 min (1-300). Complete extraction was achieved in 90.9% of the leads and partial extraction in 3.4%. Extraction failed in 5.7% of the leads. Major complications = perforations caused 10/22 (3.4/5.7%) of the failures. Most partially extracted patients were considered clinically successful, as only minor lead parts without clinical significance were left. Femoral non-laser technique was used to remove 8/12 of the non-complication failures. The total complication rate, including five minor complications (1.7%), was 5.1%. No in-hospital mortality occurred. Pacing and implantable cardioverter-defibrillator leads can safely, effectively, and predictably be extracted. Open-heart extractions can be limited to special cases. The results indicate that the traditional policy of abandoning redundant leads, instead of removing them, may be obsolete in many patients.

PV supply chain growing pains

2010-11-15

This article discussed issues involving the supply chain for photovoltaic (PV) equipment that is emerging in Ontario as a result of the Feed-in-Tariff (FIT) program that was launched in late 2009. The rapidly developing PV supply chain may not be taking a sustainable path. The domestic-content requirement is making manufacturers outlay capital to set up manufacturing in Ontario without reliable market data. Only a small number of dealer/installers have any meaningful experience designing and installing grid-tie PV. Until recently, wholesale distributors designed and supplied most grid-tie PV systems in Canada, and solar dealers/installers or electricians or electrical contractors did the installation. Instead of selling directly to dealer/installers, solar manufacturers should develop strong relationships with wholesalers, who have system design experience and product training. This would allow manufacturers to focus on their core strength, reach more customers, and keep lower inventory levels. Wholesale distributors in turn provide dealer/installers with expertise in product and system design, training from a range of manufacturers, marketing and logistics support, and immediate access to inventory. Manufacturers generally lack appropriate accounting, engineering, marketing, and logistics services to deal with a multitude of active accounts, and they are not structured to work with architects and engineers to do complete system design. Partnering with wholesale distributors allows manufacturers to take on the residential and small-scale commercial sectors by building brand awareness and increasing market share and sales across Canada. 2 figs.

Challenges of Tagging Goods in Supply Chains and a Cloud Perspective with Focus on Some Transitional Economies

Directory of Open Access Journals (Sweden)

Sanja Bauk

2017-02-01

Full Text Available This paper considers some of the barriers in implementing the RFID (radio frequency identification technology for identifying, locating, tracking and tracing goods in supply chains, along with a model for adopting cloud services that can mitigate these obstacles in the transitional environment. The analysis is based on the assessments of the implementation impediments, given by the experts in the field of logistics: university professors, assistants and entrepreneurs from three Western Balkan countries (Montenegro, Serbia, and Bosnia and Herzegovina. Since the professionals’ assessments are influenced by their experiences from the transitional economies, which are faced with limited abilities to invest in expensive business information systems, the main hypothesis is that moving the logistics into the cloud may resolve or at least alleviate the considered problems. On the basis of the available secondary literature resources on pros and cons of RFID implementation into supply chains, and the statistical analysis of the consciously completed questionnaires in the survey, the model for adopting cloud services for providing RFID-enabled goods and related activities in the considered economies is proposed at a logical level. The paper also gives some directions for further research work in this domain.

Protection of the MFTF accel power supplies

The MFTF experiment's Sustaining Neutral Beam Power Supply System (SNBPSS) includes twenty-four 95 kV, 80 A accel dc power supplies (ADCPS). Each power supply includes a relatively high-impedance (20 percent) rectifier transformer and a step voltage regulator with a 50-100 percent voltage range. With this combination, the fault current for some postulated faults may be lower than the supply's full load current at maximum voltage. A design has been developed which uses protective relays and current-limiting fuses coordinated to detect phase and ground faults, DC faults, incorrect voltage conditions, rectifier faults, power factor correction capacitor faults, and overloads. This unusual solution ensures fast tripping on potentially destructive high-current faults and long-time delays at lower currents to allow 30 second pulse operation. The ADCPS meets the LLL specification that all major assemblies be self-protecting, that is, able to sustain external faults without damage to minimize damage due to internal faults

In this research the authors examined middle school special education teachers' perceptions of assistive technology during literacy instruction with students with high incidence disabilities. A survey explored the use, effectiveness, and factors impacting use or effectiveness of assistive technology for literacy teaching and learning. Results suggested teachers' perceived assistive technology to be an effective tool for literacy, but use it minimally. When assistive technology was used, teachers indicated it was an effective literacy support. Teachers also reported barriers to using assistive technology in literacy including cost, usability, and lack of training/experience. However, factors such as previous successful experiences with assistive technology and assistive technology supporting students' learning encouraged assistive technology use. The consistency of teachers' reports of needing more experience and knowledge in assistive technology to fully use it suggests implications for preservice preparation such as providing additional experiences and information on assistive technology.

Full Text Available OBJECTIVE:To report the initial outcomes of robotic-assisted partial nephrectomy in a tertiary center in South America. MATERIAL AND METHODS: From 11/2008 to 12/2009, a total of 16 transperitoneal robotic-assisted partial nephrectomies were performed in 15 patients to treat 18 kidney tumors. One patient with bilateral tumor had two procedures, while two patients with two synchronous unilateral tumors had a single operation to remove them. Eleven (73% patients were male and the right kidney was affected in 7 (46% patients. The median patient age and tumor size were 57 years old and 30 mm, respectively. Five (28% tumors were hilar and/or centrally located. RESULTS: The median operative time, warm ischemia time and estimated blood loss was 140 min, 27 min and 120 mL, respectively. Blood transfusion was required in one patient with bilateral tumor, and one additional pyelolithotomy was performed due to a 15mm stone located in the renal pelvis. The histopathology analysis showed 15 (83% malignant tumors, which 10 (67% were clear cell carcinoma. The median hospital stay was 72 hrs and no major complication was observed. CONCLUSION: Robotic-assisted partial nephrectomy is safe and represents a valuable option to perform minimally invasive nephron-sparing surgery.

Full Text Available There is growing evidence on the importance of rehabilitation interventions promoting the persistence of the sense of self in people with Alzheimer's disease (AD or other forms of dementia. Assistive Technologies (AT may contribute to the development of interventions aimed to improve adaptive responses to environmental demands. This, in turns, can promote self-awareness. At the same time AT can manage computer interfaces able to record and reproduce autobiographical multimedia contents that can be very useful during reminiscence tasks carried out during conversations with supportive staff. These tasks could promote the self-concept. Globally the AT can be of great help in setting up rehabilitation and leisure environments promoting the experience of self in people with AD and other dementias.

Operating experience of a portable thermophotovoltaic power supply

Becker, Frederick E.; Doyle, Edward F.; Shukla, Kailash

1999-03-01

Two configurations of man-portable thermophotovoltaic (TPV) power supplies based on Thermo Power's supported continuous fiber emitter have been designed, built, and are being tested. The systems use narrow-band, fibrous, ytterbia emitters radiating to bandgap matched silicon photovoltaic arrays with dielectric stack filters for optical energy recovery and recuperators for thermal energy recovery. The systems have been designed for operation with propane and with combustion air preheat temperatures of up to 1250 K. To operate at air preheat temperatures above the auto-ignition temperature of the fuel, a unique fuel delivery system was devised which results in the micromixing and rapid combustion of the fuel and air right in the emitter fibers. This allows the ytterbia emitter fibers to run much hotter (˜2000 K) than any of the surrounding structure.

Supply chain risk management processes for resilience: A study of South African grocery manufacturers

Directory of Open Access Journals (Sweden)

Simon Simba

2017-09-01

Full Text Available Background: The supply chain risk management (SCRM process is aimed at the implementation of strategies that assist in managing both daily and exceptional risks facing the supply chain through continuous risk assessment to reduce vulnerability and ensure continuity. Purpose: The purpose of the study was to determine whether the SCRM process enables supply chain resilience among grocery manufacturers in South Africa. The fast-moving consumer goods (FMCG-manufacturing industry faces increased risk because of the nature of their products being perishable with a limited shelf life. Method: This study was conducted using a descriptive qualitative research design. Data were collected by means of 12 semi-structured interviews with senior supply chain practitioners within the South African grocery manufacturing industry. Findings: The study found that most firms informally implement SCRM processes of risk identification, assessment, mitigation and monitoring to mitigate disruptions. Furthermore, the findings indicate that the SCRM processes facilitate resilience among grocery manufacturers in South Africa. Conclusion: The managerial implications show that supply chain managers of grocery manufacturers should formalise the SCRM process and develop risk assessment scales to better prioritise risks in order to run a resilient supply chain. The research contributes to the supply chain management field by adding to the scarce literature relating to SCRM as an enabler of supply chain resilience in a South African context.

Full Text Available Background: Supply chain integration was identified as a tool to assist an organisation to survive in a competitive marketplace. It was unclear how plastic manufacturers in Gauteng perceived supply chain integration efforts between themselves and their suppliers. Objectives: This study’s main purpose was to investigate the nature and extent of supply chain integration between 10 plastic manufacturers in Gauteng and their suppliers. The focus was on these manufacturers’ commitment to and perceptions of supplier integration efforts. Method: The study was conducted with plastic manufacturing organisations in Gauteng, over a period of 2 months. A total of 10 participants were engaged through semi-structured interviews. Results: The main findings of the study revealed that commitment and trust were found to be the antecedents of supplier integration and closer collaboration, while customer price pressure and limited available resources served as motivating factors for integration efforts. Conclusion: It is recommended that organisations must revisit integration efforts when new markets are penetrated and top management support must be revisited using a strategic framework. Keywords: Supply chain integration; supply chain commitment; organisational integration; performance; visibility; supplier integration; customer integration; qualitative study; semi-structured interview; basic research.

To develop and apply a model that allows prediction of current and future supply and demand for rheumatology services in the US. A supply model was developed using the age and sex distribution of current physicians, retirement and mortality rates, the number of fellowship slots and fill rates, and practice patterns of rheumatologists. A Markov projection model was used to project needs in 5-year increments from 2005 to 2025. The number of rheumatologists for adult patients in the US in 2005 is 4,946. Male and female rheumatologists are equally distributed up to age 44; above age 44, men predominate. The percent of women in adult rheumatology is projected to increase from 30.2% in 2005 to 43.6% in 2025. The mean number of visits per rheumatologist per year is 3,758 for male rheumatologists and 2,800 for female rheumatologists. Assuming rheumatology supply and demand are in equilibrium in 2005, the demand for rheumatologists in 2025 is projected to exceed supply by 2,576 adult and 33 pediatric rheumatologists. The primary factors in the excess demand are an aging population which will increase the number of people with rheumatic disorders, growth in the Gross Domestic Product, and flat rheumatology supply due to fixed numbers entering the workforce and to retirements. The productivity of younger rheumatologists and women, who will make up a greater percentage of the future workforce, may also have important effects on supply. Unknown effects that could influence these projections include technology advances, more efficient practice methods, changes in insurance reimbursements, and shifting lifestyles. Current data suggest that the pediatric rheumatology workforce is experiencing a substantial excess of demand versus supply. Based on assessment of supply and demand under current scenarios, the demand for rheumatologists is expected to exceed supply in the coming decades. Strategies for the profession to adapt to this changing health care landscape include increasing

2017-06-20

Improving access to sanitation is a global public health priority. Sufficient consumer demand is required for sanitation coverage to expand through private provision. To measure consumer demand for hygienic latrine platform products in rural Tanzania, we conducted a randomized, voucher-based real-money sales trial with 1638 households with unimproved latrines. We also evaluated multiple supply chain options to determine the costs of supplying latrine platform products to rural households. For concrete latrine SanPlats, 60% of households were willing to pay US$0.48 and 10% of households were willing to pay US$4.05, yet the average cost of supplying the SanPlat to households was US$7.51. Similarly, for plastic sanitary platforms, willingness-to-pay (WTP) dropped from almost 60% at a price of US$1.43 to 5% at a price of US$12.29, compared to an average supply cost of US$23.28. WTP was not significantly different between villages that had participated in the National Sanitation Campaign and those that had not. Randomized informational interventions, including hygiene data-sharing and peer-based exposure to latrine platform products, had minimal effects on WTP. In conclusion, current household demand for latrine platform products is too low to achieve national goals for improved sanitation coverage through fully commercial distribution.

The Brazilian fuel substitution dilemma: Recent experience from an energy supply study

International Nuclear Information System (INIS)

Aringhoff, R.

1984-01-01

The paper is intended as a basis for discussing strategic supply options and their economic impacts for an advanced developing country. It represents a first brief assessment of an energy systems analysis project which was carried out by the Secretaria de Tecnologia do Ministerio das Minas e Energia and Kernforschungsanlage Juelich between May 1982 and May 1984. In view of the fact that Brazil had to spend 50% of its annual export revenues to import oil in 1980 and taking into account that this import bill of roughly US $10x10 9 affects the balance of payments and foreign debt burden significantly, the Brazilian Ministry of Energy and Mines decided to evaluate the consequences of alternative supply strategies utilizing domestic energy resources with priority. There is a big challenge and opportunity to develop and utilize domestic energy resources, mainly hydropower, coal for thermal uses in industry and biomass for the rural and residential sectors. Supplying the Brazilian energy system in general will not be the problem. The oil substitution dilemma becomes obvious when one looks at the specific requirements of the transport sector. For historical reasons the transport system is nearly totally based on road transport. Around two thirds of the total fuel consumption is swallowed up by this sector. Replacing crude oil means replacing gasoline and diesel. This means producing ethanol from sugar-cane and methanol from hard coal. These alternatives are leading to a significantly higher overall system cost of the energy system. The efforts of the Brazilian Government to replace imported fuel oil and ensure a self-sufficient domestic energy supply of high security were financed until now by a significant public budget deficit. This strategy will run into difficulties in the future, as the latest IMF negotiations show. One way to escape this dilemma can be a careful examination of ways to reconstruct the transport system.

Eines, Trude Fløystad; Vatne, Solfrid

2018-05-01

The aim of this study was to evaluate nurses' and nurse assistants' experiences with a design thinking approach to innovation used in a nursing home in Norway. A design thinking approach to innovation that focuses on users' needs can be employed to address many of the challenges facing health care providers in a field facing a growing ageing population, complex diseases and financial shortfalls. This study is based on a thematic analysis of four focus group interviews with nurses and nurse assistants (n = 23). In the initial phase of developing the new service model, which included defining staff roles and responsibilities, participating nurses and nurse assistants felt engaged and motivated by the designers' inclusive and creative methods. However, during the new model's testing phase, they were critical of management's lack of involvement in the model`s implementation and therefore became less motivated about the project. The findings of the study highlight the importance of the designers cooperating with management and staff for the duration of the innovation process. Challenging innovation processes require strong managers who engage with designers, patients, staff and volunteers throughout all phases of an innovation process using a design thinking approach. © 2017 John Wiley & Sons Ltd.

Patients with substance use disorders grow older thanks to effective treatments. Together with a high prevalence of comorbidities, psychological problems, and low social support, these patients are at high risk for medication non-adherence. Established treatment facilities face challenges to accommodate these complex patients within their setting. Electronic medication management aids (e-MMAs) might be appropriate to simultaneously monitor and improve adherence for these patients. We report the first long-term experiences with a novel remote electronic medication supply model for two opioid-dependent patients with HIV. John (beginning dementia, 52 years, 6 tablets daily at 12 am) and Mary (frequent drug holidays, 48 years, 5-6 tablets daily at 8 pm) suffered from disease progression due to non-adherence. We electronically monitored adherence and clinical outcomes during 659 (John) and 953 (Mary) days between July 2013 and April 2016. Both patients retrieved over 90% of the pouches within 75 min of the scheduled time. Technical problems occurred in 4% (John) and 7.2% (Mary) of retrievals, but on-site support was seldom required. Viral loads fell below detection limits during the entire observation period. Continuous medication supply and persistence with treatment of over 1.7 years, timing adherence of more than 90%, and suppressed HIV viral load are first results supporting the feasibility of the novel supply model for patients on opioid-assisted treatment and polypharmacy.

The caliber and quantity of sediment delivered to a channel influences its size and shape, yet we know little about how the sediment supply affects rivers whose geomorphic form is influenced by riparian vegetation. We present results from flume experiments that test the impact of sediment supply on plant-morphodynamic interactions. We introduced two sediment supply conditions to a 28-meter long, sand bedded flume (60 cm wide and 71 cm deep) at the UC-Berkeley Richmond Field Station: equilibrium (balance between sediment transport and supply) and deficit (transport exceeds sediment supply). We conducted ten runs with different riparian seedling configurations (individual plants or patches) and species (tamarisk or cottonwood), and stem and leaf density (0.003-0.47 cm2/cm2), under both sediment supply conditions. Plant species, size, and configuration were important in predicting the topographic adjustments that occurred during our experiments. These influences may be attributed to differences in plant morphology; tamarisk is shrubby while cottonwood is more tree-like, with a single stem and leaves concentrated higher on the plant. The plant-morphodynamic relationship, however, differed for the two sediment supply conditions. During sediment equilibrium, only patches of cottonwood served as sediment sinks compared to an unvegetated bed, but tamarisk patches had no impact on the sediment mass balance. During sediment deficit, in contrast, tamarisk patches accumulated more sediment than unvegetated beds. Stem and leaf density also controlled changes in bed elevation. During equilibrium conditions, increasing the density of cottonwood stems and leaves resulted in greater bed degradation. Conversely, aggradation occurred with increases in the density of tamarisk. For sediment deficit conditions, the relationship between stem and leaf density and the rate of bed change was negative for both species (i.e., higher density resulted in faster rate of scour). The shifting

To estimate current and future specialist neurologist demand and supply to assist with health sector planning. Current demand for the neurology workforce in New Zealand was assessed using neuroepidemiological data. To assess current supply, all New Zealand neurology departments were surveyed to determine current workforce and estimate average neurologist productivity. Projections were made based on current neurologists anticipated retirement rates and addition of new neurologists based on current training positions. We explored several models to address the supply-demand gap. The current supply of neurologists in New Zealand is 36 full-time equivalents (FTE), insufficient to meet current demand of 74 FTE. Demand will grow over time and if status quo is maintained the gap will widen. Pressures on healthcare dollars are ever increasing and we cannot expect to address the identified service gap by immediately doubling the number of neurologists. Instead we propose a 12-year strategic approach with investments to enhance service productivity, strengthen collaborative efforts between specialists and general service providers, moderately increase the number of neurologists and neurology training positions, and develop highly skilled non-specialists including trained.

Full Text Available Owing to the transparency in supply chains, enhancing competitiveness of industries becomes a vital factor. Therefore, many developing countries look for a possible method to save costs. In this point of view, this study deals with the complicated liberalization policies in the global supply chain management system and proposes a mathematical model via the flow-control constraints, which are utilized to cope with the bonded warehouses for obtaining maximal profits. Numerical experiments illustrate that the proposed model can be effectively solved to obtain the optimal profits in the global supply chain environment.

Lecture capturing assisted teaching and learning experience

Chen, Li

2015-03-01

When it comes to learning, a deep understanding of the material and a broadband of knowledge are equally important. However, provided limited amount of semester time, instructors often find themselves struggling to reach both aspects at the same time and are often forced to make a choice between the two. On one hand, we would like to spend much time to train our students, with demonstrations, step by step guidance and practice, to develop strong critical thinking skills and problem-solving skills. On the other hand, we also would like to cover a wide range of content topics to broaden our students' understanding. In this presentation, we propose a working scheme that may assist to achieve these two goals at the same time without sacrificing either one. With the help of recorded and pre-recorded lectures and other class materials, it allows instructors to spend more class time to focus on developing critical thinking skills and problem-solving skills, and to apply and connect principle knowledge with real life phenomena. It also allows our students to digest the material at a pace they are comfortable with by watching the recorded lectures over and over. Students now have something as a backup to refer to when they have random mistakes and/or missing spots on their notes, and hence take more ownership of their learning. Advanced technology have offered flexibility of how/when the content can be delivered, and have been assisting towards better teaching and learning strategies.

Evaluation of negative pressure vacuum-assisted system in acute and chronic wounds closure: our experience.

Science.gov (United States)

Chiummariello, S; Guarro, G; Pica, A; Alfano, C

2012-10-01

Negative-pressure therapy or vacuum-assisted closure (VAC) has been used in clinical applications since the 1940's and has increased in popularity over the past decade. This dressing technique consists of an open cell foam dressing put into the wound cavity, a vacuum pump produces a negative pressure and an adhesive drape. A controlled sub atmospheric pressure from 75 to 150 mmHg is applied. The vacuum-assisted closure has been applied by many clinicians to chronic wounds in humans; however it cannot be used as a replacement for surgical debridement. The initial treatment for every contaminated wound should be the necrosectomy. The VAC therapy has a complementary function and the range of its indications includes pressure sores, stasis ulcers, chronic wounds such as diabetic foot ulcers, post traumatic and post operative wounds, infected wounds such as necrotizing fasciitis or sternal wounds, soft-tissue injuries, bone exposed injuries, abdominal open wounds and for securing a skin graft. We describe our experience with the VAC dressing used to manage acute and chronic wounds in a series of 135 patients, with excellent results together with satisfaction of the patients.

, limited emotional or psychological resources, life events, and acute illness. Discussions between researchers and participants about the materials collected (and sometimes about what had prevented them completing the tasks helped elicit further information relevant to assisted living technology design. The probe materials were particularly helpful when having conversations with non-English speaking participants through an interpreter. Conclusions Cultural probe methods can help build a rich picture of the lives and experiences of older people to facilitate the co-production of assisted living technologies. But their application may be constrained by the participant’s physical, mental and emotional capacity. They are most effective when used as a tool to facilitate communication and development of a deeper understanding of older people’s needs.

Less-Conventional Low-Consumption Galvanic Separated MOSFET-IGBT Gate Drive Supply

Directory of Open Access Journals (Sweden)

Jean Marie Vianney Bikorimana

2017-01-01

Full Text Available A simple half-bridge, galvanic separated power supply which can be short circuit proof is proposed for gate driver local supplies. The supply is made while hacking a common mode type filter as a transformer, as the transformer shows a good insulation, it has a very low parasitic capacitance between primary and secondary coils, and it is cost-effective. Very low standby losses were observed during lab experiments. This makes it compatible with energy efficient drives and solar inverters.

Dual voltage power supply with 48 volt

Energy Technology Data Exchange (ETDEWEB)

Froeschl, Joachim; Proebstle, Hartmut; Sirch, Ottmar [BMW Group, Muenchen (Germany)

2012-11-01

Automotive electrics/electronics have just reached a period of tremendous change. High voltage systems for Hybrid, Plug-In Hybrid or Battery Electric Vehicles with high power electric motors, high energy accumulators and electric climate compressors will be introduced in order to achieve the challenging targets for CO{sub 2} emissions and energy efficiency and to anticipate the mobility of the future. Additionally, innovations and the continuous increase of functionality for comfort, safety, driver assistance and infotainment systems require more and more electrical power of the vehicle power supply at all. On the one hand side electrified vehicles will certainly achieve a significant market share, on the other hand side they will increase the pressure to conventional vehicles with combustion engines for fuel consumption and CO{sub 2} emissions. These vehicles will be enabled to keep their competitiveness by new functions and the optimization of their electric systems. A dual voltage power supply with 48 Volt and 12 Volt will be one of the key technologies to realize these requirements. The power capability of the existing 12 Volt power supply has reached its limits. Further potentials can only be admitted by the introduction of 48 Volt. For this reason the car manufacturers Audi, BMW, Daimler, Porsche and Volkswagen started very early on this item and developed a common specification of the new voltage range. Now, it is necessary to identify the probable systems at this voltage range and to start the developments. (orig.)

Global analysis of urban surface water supply vulnerability

International Nuclear Information System (INIS)

Padowski, Julie C; Gorelick, Steven M

2014-01-01

This study presents a global analysis of urban water supply vulnerability in 71 surface-water supplied cities, with populations exceeding 750 000 and lacking source water diversity. Vulnerability represents the failure of an urban supply-basin to simultaneously meet demands from human, environmental and agricultural users. We assess a baseline (2010) condition and a future scenario (2040) that considers increased demand from urban population growth and projected agricultural demand. We do not account for climate change, which can potentially exacerbate or reduce urban supply vulnerability. In 2010, 35% of large cities are vulnerable as they compete with agricultural users. By 2040, without additional measures 45% of cities are vulnerable due to increased agricultural and urban demands. Of the vulnerable cities in 2040, the majority are river-supplied with mean flows so low (1200 liters per person per day, l/p/d) that the cities experience ‘chronic water scarcity’ (1370 l/p/d). Reservoirs supply the majority of cities facing individual future threats, revealing that constructed storage potentially provides tenuous water security. In 2040, of the 32 vulnerable cities, 14 would reduce their vulnerability via reallocating water by reducing environmental flows, and 16 would similarly benefit by transferring water from irrigated agriculture. Approximately half remain vulnerable under either potential remedy. (letter)

Study the feasibility of hydrogen assisted renewable power for off-grid communities

International Nuclear Information System (INIS)

Wu, S.H.; Fleetwood, M.; Roberston, R.; Nielsen, N.

2004-01-01

Most Renewable energy sources lack the controllability and availability of conventional fossil fuel-based energy sources and therefore cannot meet load requirements of a community without a backup or storage system. The advances of hydrogen technologies enable these renewable energy options to supply power to remote communities relying on independent sources of electrical and other energy. The hydrogen assisted renewable power (HARP) concept promises to make renewable energy more practical and mainstream through the use of hydrogen based electrical generation systems. The study herein is the first of a multiphase project to investigate the benefits of HARP as an environmentally friendly replacement for diesel in the supply of electricity to off-grid communities and analyse its feasibility and suitability as a back-up power supply. A small-scale pilot project was selected and this study assesses the major elements of a plant required to integrate electrical generation system, hydrogen storage and hydrogen generation into a renewable energy generation system. Based on the available renewable energy profiles, a simulation model was developed to assist in selecting, integrating, and evaluating various configurations and operational scenarios. This paper describes the components of the proposed HARP system as well as its cost, benefits and opportunities for other applications. (author)

Recruiting experts for technical assistance rogramme

International Nuclear Information System (INIS)

1974-01-01

One of the objectives of the IAEA is the provision of technical assistance to its Member States to carry out their peaceful nuclear activities more efficiently and safely. This involves looking for and supplying experts, equipment and fellowships. Since 1958 the Agency has provided the services of more than 1800 experts valued at $11.5 million, 4300 fellowships valued at $14.3 million, and equipment worth $10.8 million. The efficiency of the programme can only be increased by a more prompt consideration of proposals forwarded by the Agency, and the continuing co-operation from national Governments and private institutions. The IAEA recruits an average of 200 experts a year to implement its Regular Technical Assistance Programme. These projects are financed by voluntary contributions from Member States, and by the United Nations Development Programme for those projects for which the IAEA is the executing agency

2013-01-01

These studies are part of a project aiming to reveal relevant aspects of human-dog interactions, which could serve as a model to design successful human-robot interactions. Presently there are no successfully commercialized assistance robots, however, assistance dogs work efficiently as partners for persons with disabilities. In Study 1, we analyzed the cooperation of 32 assistance dog-owner dyads performing a carrying task. We revealed typical behavior sequences and also differences depending on the dyads' experiences and on whether the owner was a wheelchair user. In Study 2, we investigated dogs' responses to unforeseen difficulties during a retrieving task in two contexts. Dogs displayed specific communicative and displacement behaviors, and a strong commitment to execute the insoluble task. Questionnaire data from Study 3 confirmed that these behaviors could successfully attenuate owners' disappointment. Although owners anticipated the technical competence of future assistance robots to be moderate/high, they could not imagine robots as emotional companions, which negatively affected their acceptance ratings of future robotic assistants. We propose that assistance dogs' cooperative behaviors and problem solving strategies should inspire the development of the relevant functions and social behaviors of assistance robots with limited manual and verbal skills.

Interprofessional Education Perceptions of Dental Assisting and Radiologic Technology Students Following a Live Patient Experience.

Science.gov (United States)

Reddington, Amanda R; Egli, Amy J; Schmuck, Heather M

2018-05-01

Health professions students are often unaware of other health care providers' roles or professional expertise due to most education taking place within their single profession. This pattern may be even more prevalent for baccalaureate and associate degree programs since most interprofessional education (IPE) occurs in predoctoral programs and, when IPE is incorporated into allied health professions education, it often utilizes simulation instead of live patient experiences. The aim of this study was to determine if radiologic technology and dental assisting students' perceptions changed regarding interprofessional practice and teamwork after an IPE activity with actual patients. The participants were students in the University of Southern Indiana (USI) radiologic technology and dental assisting programs. This mixed-methods pilot study conducted in 2017 collected quantitative and qualitative data from pre and post surveys, the researchers' observations of student interactions during live patient assessment and acquisition of panoramic images, and large-group discussion. Twenty-five of the 26 students who participated in the IPE program completed both pre and post surveys, for a 96% response rate. The results showed significant differences in the participants' perceptions from the pre to post surveys on a wide variety of survey items. Most notable were the positive changes in perceptions related to trust in judgment of others within their profession (p=0.001), relationships with other professions (p=0.002), and thinking highly of other professions (p=0.002). Overall, this study found that incorporating the IPE activity with a live patient into these radiologic technology and dental assisting programs improved the students' perceptions of other allied health professionals. Future research should include more participants to increase sample size and add quantitative data collection.

New developments in employee assistance programs.

White, R K; McDuff, D R; Schwartz, R P; Tiegel, S A; Judge, C P

1996-04-01

Employee assistance programs have developed from alcoholism assessment and referral centers to specialized behavioral health programs. Comprehensive employee assistance programs are defined by six major components: identification of problems based on job performance, consultation with supervisors, constructive confrontation, evaluation and referral, liaison with treatment providers, and substance abuse expertise. Other services have been added as enhancements to the basic model and include managed behavioral health activities and professional assistance committees, which provide services for impaired professionals and executives. Recent developments in the field are illustrated through examples from the experience of the employee assistance program at the University of Maryland Medical System in Baltimore.

Becoming physics people: Development of integrated physics identity through the Learning Assistant experience

Science.gov (United States)

Close, Eleanor W.; Conn, Jessica; Close, Hunter G.

2016-06-01

[This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] In this study, we analyze the experience of students in the Physics Learning Assistant (LA) program at Texas State University in terms of the existing theoretical frameworks of community of practice and physics identity, and explore the implications suggested by these theories for LA program adoption and adaptation. Regression models from physics identity studies show that the physics identity construct strongly predicts intended choice of a career in physics. The goal of our current project is to understand the details of the impacts of participation in the LA experience on participants' practice and self-concept, in order to identify critical elements of LA program structure that positively influence physics identity and physics career intentions for students. Our analysis suggests that participation in the LA program impacts LAs in ways that support both stronger "physics student" identity and stronger "physics instructor" identity, and that these identities are reconciled into a coherent integrated physics identity. Increased comfort in interactions with peers, near peers, and faculty seems to be an important component of this identity development and reconciliation, suggesting that a focus on supporting community membership is useful for effective program design.

Effect of haptic assistance on learning vehicle reverse parking skills.

Hirokawa, Masakazu; Uesugi, Naohisa; Furugori, Satoru; Kitagawa, Tomoko; Suzuki, Kenji

2014-01-01

Compared to conventional visual- and auditory-based assisted driving technologies, haptic modality promises to be more effective and less disturbing assistance to the driver. However, in most previous studies, haptic assistance systems were evaluated from safety and stability viewpoints. Moreover, the effect of haptic assistance on human driving behavior has not been sufficiently discussed. In this paper, we introduce an assisted driving method based on haptic assistance for driver training in reverse parking, which is considered as an uncertain factor in conventional assisted driving systems. The proposed system assists the driver by applying a torque on the steering wheel to guide proper and well-timed steering. To design the appropriate assistance method, we conducted a measurement experiment to determine the qualitative reverse parking driver characteristics. Based on the determined characteristics, we propose a haptic assistance calculation method that utilizes the receding horizon control algorithm. For a simulation environment to assess the proposed assistance method, we also developed a scaled car simulator comprising a 1/10 scaled robot car and an omnidirectional camera. We used the scaled car simulator to conduct comparative experiments on subjects, and observed that the driving skills of the assisted subjects were significantly better than those of the control subjects.

Logistics of long distance FDG supply

2003-01-01

Full text: The short half-life of 18 F-FDG (110 mins) presents a logistical problem when transport over long distances is involved. Our facility was presented with such a problem when we were contracted to supply FDG on a regular basis to the Royal Adelaide Hospital over 700 km away. The principal difficulties to be overcome were providing a quick, reliable and efficient transport system, the development of a safe and efficacious transport packaging system, production and supply of sufficient product and the scheduling of the operations of the cyclotron, radiochemistry and radiopharmacy services, so as not to interfere with the existing clinical program of the PET centre. Together with the assistance of Gammasonics, an FDG transport and packaging system was developed which complied with transport regulations and was recyclable. A door-to-door courier system was established which, on average, takes four hours but has occasionally been hampered by the unreliability of the airline service. A schedule for early operation of the cyclotron and radio-chemistry was established to meet with transport schedules. A system of quality control of the FDG was instituted (while the product is in transit) with the QC release results being faxed to the recipient prior to the product's arrival. We have supplied 51 deliveries since mid-September 2000 to the end of February 2001. During this period there have been 6 (11.7%) delayed deliveries of which 2 (3.9%) have been due to cyclotron operational problems and 4 (7.8%) have been due to flight delays beyond our control. There have been no completely failed deliveries. Copyright (2003) The Australian and New Zealand Society of Nuclear Medicine Inc

Malpas, Phillipa J; Wilson, Maria K R; Rae, Nicola; Johnson, Malcolm

2014-04-01

Physician-assisted dying at the end of life has become a significant issue of public discussion. While legally available in a number of countries and jurisdictions, it remains controversial and illegal in New Zealand. The study aimed to explore the reasons some healthy older New Zealanders oppose physician-assisted dying in order to inform current debate. Recorded interviews were transcribed and analysed by the authors after some edits had been made by respondents. In all, 11 older participants (over 65 years) who responded to advertisements placed in Grey Power magazines and a University of Auckland email list were interviewed for around 1 h and asked a number of open-ended questions. Four central themes opposing physician-assisted dying were identified from the interviews: one's personal experience with health care and dying and death, religious reasoning and beliefs, slippery slope worries and concern about potential abuses if physician-assisted dying were legalised. An important finding of the study suggests that how some older individuals think about physician-assisted dying is strongly influenced by their past experiences of dying and death. While some participants had witnessed good, well-managed dying and death experiences which confirmed for them the view that physician-assisted dying was unnecessary, those who had witnessed poor dying and death experiences opposed physician-assisted dying on the grounds that such practices could come to be abused by others.

Basis for the power supply reliability study of the 1 MW neutron source

International Nuclear Information System (INIS)

McGhee, D.G.; Fathizadeh, M.

1993-01-01

The Intense Pulsed Neutron Source (IPNS) upgrade to 1 MW requires new power supply designs. This paper describes the tools and the methodology needed to assess the reliability of the power supplies. Both the design and operation of the power supplies in the synchrotron will be taken into account. To develop a reliability budget, the experiments to be conducted with this accelerator are reviewed, and data is collected on the number and duration of interruptions possible before an experiment is required to start over. Once the budget is established, several accelerators of this type will be examined. The budget is allocated to the different accelerator systems based on their operating experience. The accelerator data is usually in terms of machine availability and system down time. It takes into account mean time to failure (MTTF), time to diagnose, time to repair or replace the failed components, and time to get the machine back online. These estimated times are used as baselines for the design. Even though we are in the early stage of design, available data can be analyzed to estimate the MTTF for the power supplies

Electrical power supplies of nuclear plants are very complex systems. They are studied in many ways: failure consequences, probabilistic risk assessement, failure diagnosis, corrective actions in case of incident ... Knowledge base technology (expert systems) is very suited to solve these problems. A common structural representation can generate specific functional representations; thus we get coherency and easy evolution. This paper shows a two facet methodology: the plant description (both static and dynamic) and reasoning about it. Current applications are developed for pressurized water reactors and gas cooled reactors, using the SPIRAL expert system shell buil at CEA [fr

1998-01-01

Two 1.4 MW high voltage power supply (HVPS) modules with 3-5 s pulse duration have been developed for LHCD experiment in the HT-7 tokamak. The power source consists of a pulsed generator and the electric circuit. Duration of the ultra-long-pulse is controlled by switching-on dc relay immediately and switching-off ac contactor after a given time, and the fast protection is executed by a crowbar. Due to the soft starting of the power source, the problem of overvoltage induced by dc relay switching-on has been solved. Each power supply module outputs a rated power (-35 kV, 40 A) on the dummy load. With the klystrons connected as the load of the power supply modules, LHCD experiments have been conducted successfully in the HT-7 tokamak

Motivation of health workers is a critical component of performance and is shaped by multiple factors. This study explored factors that influence motivation of health surveillance assistants (HSAs) in Malawi, with the aim of identifying interventions that can be applied to enhance motivation and performance of HSAs. A qualitative study capturing the perspectives of purposively selected participants was conducted in two districts: Salima and Mchinji. Participants included HSAs, health managers, and various community members. Data were collected through focus group discussions (n = 16) and in-depth interviews (n = 44). The study sample was comprised of 112 women and 65 men. Qualitative data analysis was informed by existing frameworks on factors influencing health worker motivation. Our analysis identified five key themes shaping HSA motivation: salary, accommodation, human resource management, supplies and logistics, and community links. Each of these played out at different levels-individual, family, community, and organisational-with either positive or negative effects. Demotivating factors related primarily to the organisational level, while motivating factors were more often related to individual, family, and community levels. A lack of financial incentives and shortages of basic supplies and materials were key factors demotivating HSAs. Supervision was generally perceived as unsupportive, uncoordinated, and top-down. Most HSAs complained of heavy workload. Many HSAs felt further recognition and support from the Ministry of Health, and the development of a clear career pathway would improve their motivation. Factors shaping motivation of HSAs are complex and multilayered; experiences at one level will impact other levels. Interventions are required to enhance HSA motivation, including strengthening the supervision system, developing career progression pathways, and ensuring clear and transparent incentives. HSAs have unique experiences, and there is need to hear

Supplying astronauts with adequate food and water on short and long-term space flights is discussed based on experiences gained in space flight. Food consumption, energy requirements, and suitability of the foodstuffs for space flight are among the factors considered. Physicochemical and biological methods of food production and regeneration of water from astronaut metabolic wastes, as well as wastes produced in a closed ecological system, or as a result of technical processes taking place in various spacecraft systems are suggested for long-term space flights.

Alignment of global supply networks based on strategic groups of supply chains

Directory of Open Access Journals (Sweden)

Nikos G. Moraitakis

2017-09-01

Full Text Available Background: From a supply chain perspective, often big differences exist between global raw material suppliers’ approaches to supply their respective local markets. The progressing complexity of large centrally managed global supply networks and their often-unknown upstream ramifications increase the likelihood of undetected bottlenecks and inefficiencies. It is therefore necessary to develop an approach to strategically master the upstream complexity of such networks from a holistic supply chain perspective in order to align regional competitive priorities and supply chain structures. The objective of this research is hence to develop an approach for the supply-chain-based alignment of complex global supply networks. Method: We review existing literature from the fields of supply chain and network management, strategic sourcing, and strategic management. Based on the literature review and theoretical and practical considerations we deduce a conceptual approach to consider upstream supply chain structures in supply network alignment initiatives. Results: On the basis of these considerations and current empirical literature we transfer strategic group theory to the supply network management context. The proposed approach introduces strategic groups of supply chains as a segmentation criterion for complex global supply networks which enables the network-wide alignment of competitive priorities. Conclusion: Supply-chain-based segmentation of global supply network structures can effectively reduce the complexity, firms face when aiming to strategically align their supply chains on a holistic level. The results of this research are applicable for certain types of global supply networks and can be used for network alignment and strategy development. The approach can furthermore generate insights useable for negotiation support with suppliers.

Full Text Available Minimizing the total cost is absolutely the goal of each supply chain, which is most of the time pursued. In this regards, quality related costs that have significant roles are sometimes neglected. Selecting suppliers, which supply relatively high quality raw materials in a lower cost is considered as a strategic decision. Make or Buy decision can be also noticed in supplier selection process. In this paper, the supply strategy: Make or Buy decision (SS: MOB is studied in order to find which strategy (Make or Buy should be chosen to minimize the total costs of supply chain. Therefore, two separate models are generated for each strategy and several examples are solved for the respective models. Computational experiments show the efficiency of the proposed models for making decision about selecting the best strategy.

Water supply

International Nuclear Information System (INIS)

Peterson, F.L.

Options and methodologies for the development of fresh water supplies on Bikini Atoll are much the same as those practiced in the rest of the Marshall Islands and for that matter, most atolls in the central Pacific Ocean Basin. That is, rainfall distribution on Bikini produces a distinct wet season, lasting from about May through November, with the remaining months being generally dry. As a result, fresh water from surface catchments tends to be plentiful during the wet season? but is usually scarce during the dry months, and alternative sources such as groundwater must be utilized during this time. On Bikini the problems of fresh water supply are somewhat more difficult than for most Marshall Island atolls because rainfall is only about half the Marshall Island's average. Tus water supply is a critical factor limiting the carrying capacity of Bikini Atoll. To address this problem BARC has undertaken a study of the Bikini Atoll water supply. Te primary objectives of this work are to determine: (1) alternatives available for fresh water supply, 2 the amounts, location and quality of available supplies and 3 optimal development methods. The study planned for one's year duration, has been underway only since the summer of 1985 and is thus not yet fully completed. However, work done to date, which is presented in this report of preliminary findings, provides a reasonably accurate picture of Bikini's fresh water supplies and the various options available for their development. The work remaining to be completed will mainly add refinements to the water supply picture presented in the sections to follow

On the modelling of linear-assisted DC-DC voltage regulators for photovoltaic solar energy systems

Science.gov (United States)

Martínez-García, Herminio; García-Vílchez, Encarna

2017-11-01

This paper shows the modelling of linear-assisted or hybrid (linear & switching) DC/DC voltage regulators. In this kind of regulators, an auxiliary linear regulator is used, which objective is to cancel the ripple at the output voltage and provide fast responses for load variations. On the other hand, a switching DC/DC converter, connected in parallel with the linear regulator, allows to supply almost the whole output current demanded by the load. The objective of this topology is to take advantage of the suitable regulation characteristics that series linear voltage regulators have, but almost achieving the high efficiency that switching DC/DC converters provide. Linear-assisted DC/DC regulators are feedback systems with potential instability. Therefore, their modelling is mandatory in order to obtain design guidelines and assure stability of the implemented power supply system.

A new technology aimed at re-establishing a global sulphur supply/demand balance

International Nuclear Information System (INIS)

Slavens, A.F.; Jorgensen, C.; Ogg, D.

2009-01-01

The world's sulphur supply is mainly determined by involuntary production of elemental sulphur during the processing of oil and gas. As a result, sulphur supply is decoupled from demand, resulting in an imbalance between the two. For almost two decades, sulphur supply has exceeded demand, which has raised significant concerns for oil and gas producers such as where to store all of the excess sulphur, and how to transport a low-value commodity to market in an economically attractive fashion. Black and Veatch is involved in the development of a new technology called sulphur to energy process (STEP TM ) which has the potential to assist in balancing global sulphur supply and demand, as well as affording other benefits such as low-emission energy production. This paper presented the potential merits of the STEP as a means to reestablish a global sulphur supply/demand balance for the world trading market. It explored the other potential benefits that may result from the use of this new technology and compared STEP to other technologies and operating schemes that regulate sulphur supply. It was concluded that STEP has the potential to allow the processor to produce elemental sulphur when demand is high, or to provide safe and ecological disposal when demand is low, with the added benefits of energy recovery from the sulphur combustion process, and sour gas reservoir sweetening over time as sulphur dioxide reacts with hydrogen sulphide present in the reservoir. 13 refs., 3 tabs., 22 figs

Control Towers in Supply Chain Management - Past and Future

Directory of Open Access Journals (Sweden)

Anna Trzuskawska-Grzesińska

2017-02-01

Full Text Available The global economy requires global supply chain management which relies on visibility and responsiveness. Determinants such as: information technology tools, process knowledge, sales and operations planning experiences, etc., enable the formation of theory and practice for the supply chain control tower concept. The goal of the research paper is to identify business examples of different approaches to the supply chain control tower in the past and initiate a discussion on their future. This paper synthesizes past control tower practices and identifies possible future trends. The author performed: literature analysis, three selected companies' case studies and comparative analyses. As the control towers evolve, while supply chains are transforming continuous, update from the market is needed. The research findings showed the selected companies, in the future, perceived control tower's activities as a potential source of revenue not just solely a source of cost and time optimization as well as a source of value added to customer. The researched control towers were built and still they are developed. The business frequently changes and requires control towers to be adjusted, reengineered and adaptive. The researched control towers are needed to keep control over supply chain while it is transforming. There is a differentiation between the supply chain control towers, logistic services control towers and reverse supply chain control towers. An integration mechanism between the control towers would be necessary to assure entire supply chain visibility and orchestration. The research also shows the knowledge gap regarding the control towers in supply chain, specially their possible configurations and future.

This study aimed to compare the effects of computer-assisted, text-based and computer-and-text learning conditions on the performances of 3 groups of medical students in the pre-clinical years of their programme, taking into account their academic achievement to date. A fourth group of students served as a control (no-study) group. Participants were recruited from the pre-clinical years of the training programmes in 2 medical schools in Japan, Jichi Medical School near Tokyo and Kochi Medical School near Osaka. Participants were randomly assigned to 4 learning conditions and tested before and after the study on their knowledge of and skill in performing an abdominal examination, in a multiple-choice test and an objective structured clinical examination (OSCE), respectively. Information about performance in the programme was collected from school records and students were classified as average, good or excellent. Student and faculty evaluations of their experience in the study were explored by means of a short evaluation survey. Compared to the control group, all 3 study groups exhibited significant gains in performance on knowledge and performance measures. For the knowledge measure, the gains of the computer-assisted and computer-assisted plus text-based learning groups were significantly greater than the gains of the text-based learning group. The performances of the 3 groups did not differ on the OSCE measure. Analyses of gains by performance level revealed that high achieving students' learning was independent of study method. Lower achieving students performed better after using computer-based learning methods. The results suggest that computer-assisted learning methods will be of greater help to students who do not find the traditional methods effective. Explorations of the factors behind this are a matter for future research.

An integrated mine development and supply system

Energy Technology Data Exchange (ETDEWEB)

Muguira, T. [Brambles Coal Services, Newcastle, NSW (Australia)

1998-12-31

In the face of intense global competition and other business pressures on coal miners, ongoing quality initiatives and continuous process improvements are needed to enhance business performance. By viewing a minesite interms of key processes, rather than departments, and employing innovative technologies and better applying organisational resources, there exists enormous potential to achieve reductions in process cost and time. The paper identifies and selects one critical coal mining process, namely the supply system, to think about how productivity improvements might occur and what changes might be employed to enhance overall system performance. While the supply system is one of few processes existing at a minesite, the paper addresses only the supply process, but includes interaction across traditional interdepartmental boundaries. The paper has been prepared for a wide audience and is based on experience and observation at several underground mines however some of the concepts are a result of dreaming in the face of global competition. 3 refs., 1 tab.

A contribution to the energy supply of innovative drive-by-wire vehicle concepts; Beitrag zur Energieversorgung innovativer Drive-by-Wire-Fahrzeugkonzepte

Energy Technology Data Exchange (ETDEWEB)

Sieglin, Erik

2009-07-01

Due to an increasing number of functions and driver assistance systems, the architecture of modern vehicles ever becomes more complex. This especially results in an increasing expenditure with the integration of new assistance systems. In order to oppose against this trend, one approach is the centralization of data processing. In this case, a drive-by-wire architecture without mechanical relapse level particularly is suitable. The contribution under consideration therefore supplies methods and approaches with which a suitable power supply is specified and realized. Their function can be verified. Apart from the aspects in terms of safety engineering, board specific questions are observed. The explanation of the procedure takes place using a prototypical structure as an example. Additionally, the hardware-in-the-loop-simulator and the processing of the tests are described.

A Laboratory Experiment on the Evolution of a Sand Gravel Reach Under a Lack of Sediment Supply

Science.gov (United States)

Orru, C.; Chavarrias, V.; Ferrara, V.; Blom, A.

2014-12-01

A flume experiment was conducted to examine the evolution of a sand-gravel reach under a lack of sediment supply. The experimental data are used to validate a numerical sand-gravel model. A bed composed of a bi-modal sediment mixture is installed with a uniform slope and an imposed gradual fining pattern. Initially, the sand fraction gradually increases in streamwise direction until the bed is fully composed of sand. The water discharge and downstream water level were constant, and the sediment feed rate was equal to zero. The experiment was dominated by bed load, partial transport, and a subcritical flow regime was imposed. The flow rate was such that only sand was mobile (partial transport), which led to a coarsening over the upstream reach and a gradual reduction of the sediment transport rate during the experiment. New equipment was used to measure the evolution of the grain size distribution of the bed surface during the experiment over the entire flume using image analysis. In the upstream reach we observed a gradual coarsening over time and the formation of an armour layer, which resulted in a more abrupt transition in grain size of the bed surface. Bed degradation increased in streamwise direction. This is due to the initial streamwise increase in the availability of sand in the bed. The different volume fraction content of sand in the bed allowed for the gravel to sink more in the downstream part of the upstream reach. The sand reach suffered from a larger degradation. Finally, we see one reach dominated by sand, small bedforms, and a small bed slope, and a gravel reach dominated by a larger bed slope.

Supply chain management/ Some lessons learned the hard way.

Science.gov (United States)

Nuttall, Stephen

2013-01-01

This paper will look at some of the experiences, lessons and frustrations experienced in managing supply chains for business continuity. No-one has time to make all the mistakes, nor to learn all the lessons on their own, so it is useful to share experiences. Over the last 25 years, the author has been involved in supply chain management as a contract manager; a programme and project manager; and as a business continuity manager. Although times change, there are some fundamental principles that are absolutely critical in making sure that supply chains do what they are needed to do/ to keep business going. Supply chains are here to stay. Indeed, with today's drive towards outsourcing, best-shoring and contracting out, they are becoming more important every year and this will only continue over time. Moreover, in the highly competitive markets in which all organisations operate, suppliers may well be carrying out operations that not all that long ago would have been considered to be part of core business. Getting the right relationship with the supply chain is more critical than ever before.1 What does this mean to business continuity professionals? They need to think not just about their own BC plans, but about the plans of their suppliers, and even those of their suppliers' suppliers. This may seem obvious, but unlike internal BC plans written by and for an organisation, it must be considered just what a supplier's plans are designed to achieve. What business outcomes will their plans deliver? If they recover their own business, how does that affect the business they serve? Are others' assumptions of how they will react in line with theirs?

Pharmacy student decision making in over-the-counter medicine supply: A critical incident study.

Science.gov (United States)

McMillan, Sara S; Thangarajah, Thachaayini; Anderson, Claire; Kelly, Fiona

2017-09-28

Various factors influence decision making in over-the-counter (OTC) medicine consultations, yet limited studies have focused, in-depth, on the thought process of pharmacy staff. This includes pharmacy students as pharmacists-in-training. To explore the factors that influence pharmacy students' decisions in relation to OTC consultations and choice of OTC medicine/s. Semi-structured interviews using the critical incident technique were undertaken with ten pharmacy students in Australia, who also worked as part-time pharmacy staff. Nine key themes were identified to influence pharmacy student decision making in OTC consultations, including customer response, confidence and scope of practice. Product requests were reported as more challenging due to customer expectations and experiences in other pharmacies, states or countries. Although negative customer response influenced some students to supply medicines in contradiction of evidence, an overarching concern for safety meant that a medicine was only supplied if unlikely to cause harm. Students reported developing confidence in OTC decision making more from real-life practice than university training; greater confidence was identified for inquiries more frequently experienced in the pharmacy. Students perceived that customers had assumptions around support staff, and were happier to talk to students than assistants. This study further identified that OTC decision making is a complex process for pharmacy students. Additional opportunities for experiential learning within this area are suggested, such as work-based placements or in-class activities such as role-plays with simulated patients.

In order to cross more rapidly the 82 weak spin resonances caused by the horizontal tune and the partial snakes, we plan to jump the horizontal tune 82 times during the acceleration of polarized protons. The current in the magnets creating this tune jump will rise in 100 (micro)s, hold flat for about 4 ms and fan to zero in 100 (micro)s. Laminated beam transport quadrupole magnets have been recycled by installing new two turn coils and longitudinal laminated pole tip shims that reduce inductance and power supply current. The power supply uses a high voltage capacitor discharge to raise the magnet current, which is then switched to a low voltage supply, and then the current is switched back to the high voltage capacitor to zero the current. The current in each of the magnet pulses must match the order of magnitude change in proton momentum during the acceleration cycle. The magnet, power supply and operational experience are described

2002-01-01

The design of the JT-60U tokamak, the configuration of the coil power supplies, and the operational experiences gained to date are reviewed. JT-60U is a large tokamak upgraded from the original JT-60 in order to obtain high plasma current, large plasma volume, and highly elongated divertor configurations. All components inside the toroidal magnetic field coils, such as vacuum vessel, poloidal magnetic field coils, divertor, etc., were modified. Various technologies and ideas were introduced to develop these components; for example, a multi-arc double skin wall structure for the vacuum vessel and a functional poloidal magnetic field coil system with taps for obtaining various plasma configurations. Furthermore, boron-carbide coated carbon fiber composite (CFC) tiles were used as divertor tiles to reduce erosion of carbon-base tiles. Later, a semiclosed divertor with pumps, for which cryo-panels originally used for NBI units were converted, was installed in the replacement of the open divertor. These development and operational results provide data for future tokamaks. Major failures experienced in the long operational period of JT-60U, such as water leakage from the toroidal magnetic field coil, fracture of carbon tiles, and breakdown of a filter capacitor, are described. As a maintenance issue for tokamaks using deuterium fueling gas, a method for reducing radiation exposure of in-vessel workers is described

Assistive/Socially Assistive Robotic Platform for Therapy and Recovery: Patient Perspectives

Matthew White

2013-01-01

Full Text Available Improving adherence to therapy is a critical component of advancing outcomes and reducing the cost of rehabilitation. A robotic platform was previously developed to explore how robotics could be applied to the social dimension of rehabilitation to improve adherence. This paper aims to report on feedback given by end users of the robotic platform as well as the practical applications that socially assistive robotics could have in the daily life activities of a patient. A group of 10 former and current patients interacted with the developed robotic platform during a simulated exercise session before taking an experience-based survey. A portion of these participants later provided verbal feedback as part of a focus group on the potential utility of such a platform. Identified applications included assistance with reaching exercise goals, managing to-do lists, and supporting participation in social and recreational activities. The study participants expressed that the personality characteristics of the robotic system should be adapted to individual preferences and that the assistance provided over time should align with the progress of their recovery. The results from this study are encouraging and will be useful for further development of socially assistive robotics.

Contract Coordination in Dual Sourcing Supply Chain under Supply Disruption Risk

Directory of Open Access Journals (Sweden)

Tong Shu

2015-01-01

Full Text Available This paper explores a coordination model for a three-echelon supply chain including two different manufacturers, one distributer and one retailer via the combined option and back contracts. And one manufacturer provides the high wholesale price with low supply disruption risk and the other is completely the opposite. This differs from the previous supply chain coordination model. Firstly, supply disruption is added to the three-echelon supply chain. Secondly, considering the coordination of the supply chain, we deploy the combined option and back contracts which are seldom used in the previous study. Furthermore, it is interesting that supply disruption risk and buyback factor do not affect the distributor’s order quantity from the manufacturer who has low product price and unreliable operating ability, while the order quantity increases with the rise of option premium and option strike price. The distributor’s order quantity from the manufacturer, which has high product price and reliable operating ability, increases with the rise of supply disruption risk but decreases when the buyback factor, option premium, and option strike price decrease.

An evaluation of the procedures required to ensure consistent material supply in the Eastern Cape automotive industry

Directory of Open Access Journals (Sweden)

GS Horn

2014-07-01

Full Text Available There is a common perception that logistics practice and supply chain management have not yet reached the required international standards among all the supply chain members in the South African automotive industry. This article is based on a research study that investigated possible reasons for the inconsistent supply of materials in the Eastern Cape automotive industry specifically. Problems identified include the fact that suppliers are not evaluated on a regular basis and do not receive sufficient logistics training, while a commitment and will to development local suppliers is lacking. Recommendations made to the South African automotive industry include the improvement of development programmes to assist local suppliers in becoming world-class suppliers, better logistics training, more regular supplier assessments, as well as improved mutual communication among suppliers and motor vehicle assemblers.

Experiences of undergraduate nursing students in peer assisted learning in clinical practice: a qualitative systematic review.

Science.gov (United States)

Carey, Matthew C; Kent, Bridie; Latour, Jos M

2018-05-01

The objective of this qualitative systematic review was to identify and synthesize the best available evidence on experiences of peer assisted learning (PAL) among student nurses in clinical practice so as to understand the value of PAL for this population. Peer-assisted learning considers the benefits of peers working in collaboration and supporting each other in professional roles. This approach to facilitate learning is effective within universities, but there is limited exploration within the clinical practice environment. Within the UK, 50% of student nurses' learning is undertaken within clinical practice, providing a large portion of student allocation within these areas, but is unexplored in relation to PAL. Therefore, existing evidence examining PAL in clinical practice needs further exploration for a better understanding of its value to student nurses' learning. The systematic review considered studies that included male and female nursing students aged 18-50 years that explored undergraduate nursing students' experiences of PAL within the clinical practice environment. Studies that utilized designs such as phenomenology, grounded theory, ethnography, action research and feminist research were considered. Other text such as opinion papers and reports were to be considered if no qualitative studies could be located. The review excluded quantitative studies, as well as those addressing PAL outside the nursing profession and students within the nursing profession but not including undergraduate student nurses. This review considered studies that included aspects related to experiences of PAL in the clinical practice setting, as seen by undergraduate nursing students and the researcher.

Sources of population and family planning assistance.

Science.gov (United States)

1983-01-01

This document assesses the current status of population and family planning assistance throughout the world and provides brief sketches of the available sources including national governments, intergovernmental agencies such as the UNFPA and other UN entities, and nongovernmental funding, technical assistance, or funding and technical assistance organizations. The descriptions of aid-granting organizations describe their purposes, sources of funding, and activities, and give addresses where further information may be sought. At present about $100 million of the US $1 billion spent for family planning in developing countries each year comes from individuals paying for their own supplies and services, over $400 million is spent by national governments on their own programs, and about $450 million comes from developed country governments and private agencies. Over half of external assistance appears to be channeled through international agencies, and only a few countries provide a substantial proportion of aid bilaterally. In the past decade several governments, particularly in Asia, significantly increased the share of program costs they assumed themselves, and the most populous developing countries, China, India, and Indonesia, now contribute most of the funding for their own programs. Although at least 130 countries have provided population aid at some time, most is given by 12 industrialized countries. The US Agency for International Development (USAID) is the largest single donor, but the US share of population assistance has declined to 50% of all assistance in 1981 from 60% in the early 1970s. Governments of Communist bloc countries have made only small contributions to international population assistance. Most governmental asistance is in cash grant form, but loans, grants in kind, and technical assistance are also provided. Private organizations give assistance primarily to other private organizations in developing countries, and have been major innovators in

Uniportal video-assisted thoracoscopic surgery (VATS) lobectomy is an emerging technique for the surgical resection of non-small cell lung cancer (NSCLC). Besides its wide debates on safety and efficacy throughout the world, there were few report on uniportal VATS from the Eastern countries. In this article, we summarized our primary experience on uniportal VATS lobectomy in an Eastern center. From October 2013 till February 2014, 54 consecutive uniportal VATS lobectomy were performed in the Department of Thoracic Surgery, Zhongshan Hospital of Fudan University. Patients' clinical features and operative details were recorded. Post-operatively, the morbidity and mortality were recorded to analyze the safety and efficacy of uniportal VATS lobectomy for NSCLCs. Among the 54 planned uniportal VATS lobectomy, there was one conversion to mini-thoracotomy due to lymph node sticking. Extra ports were required in two patients. The uniportal VATS lobectomy was achieved in 51 out of 54 patients (94.4%). The average operation duration was 122.2±37.5 min (90-160 min). The average volume of estimated blood loss during the operation was 88.8±47.1 mL (50-200 mL). The mean chest tube duration and hospital stay were 3.2±1.9 days and 4.6±2.0 days, respectively. There was no postoperative mortality in this study. Two patients suffered from prolonged air leakage (5 and 7 days), and one atrial fibrillation was observed in this cohort. Based on our primary experience, uniportal VATS lobectomy is a safe and effective procedure for the surgical resection of NSCLCs. The surgical refinements and instrumental improvements would facilitate the technique. Further studies based on larger population are required to determine its benefits towards patients with NSCLCs.

Older adults' preferences to remain independent in their own homes along with the high costs of nursing home care have motivated the development of Ambient Assisted Living (AAL) technologies which aim at improving the safety, health conditions and wellness of the elderly. This paper reports hands-on experiences in designing, implementing and operating UbiCare, an AAL based prototype system for elderly home care monitoring. The monitoring is based on the recording of environmental parameters like temperature and light intensity as well as micro-level incidents which allows one to infer daily activities like moving, sitting, sleeping, usage of electrical appliances and plumbing components. The prototype is built upon inexpensive, off-the-shelf hardware (e.g., various sensors, Arduino microcontrollers, ZigBee-compatible wireless communication modules) and license-free software, thereby ensuring low system deployment costs. The network comprises nodes placed in a house's main rooms or mounted on furniture, one wearable node, one actuator node and a centralized processing element (coordinator). Upon detecting significant deviations from the ordinary activity patterns of individuals and/or sudden falls, the system issues automated alarms which may be forwarded to authorized caregivers via a variety of communication channels. Furthermore, measured environmental parameters and activity incidents may be monitored through standard web interfaces.

United States-assisted studies on dose reconstruction in the former Soviet Union

International Nuclear Information System (INIS)

Anspaugh, L.R.; Bouville, A.

1995-12-01

Following the Chernobyl accident, the US and the USSR entered into an agreement to work on the safety of civilian nuclear reactors; one aspect of that work was to study the environmental transport and health effects of radionuclides released by the accident. After the break-up of the USSR separate agreements were established between the US and Ukraine, Belarus, and Russia to continue work on dose reconstruction and epidemiologic studies of health effects from exposure to external radiation and the incorporation of radionuclides. Studies in Belarus and Ukraine related to the Chernobyl accident now emphasize epidemiologic: studies of childhood-thyroid cancer and leukemia, and eye-lens-cataract formation in liquidators. Supporting studies on dose reconstruction emphasize a variety of ecological, physical, and biological techniques. Studies being conducted in Russia currently emphasize health effects in the workers and the population around the Mayak Industrial Association. As this production complex is an analogue of the US Hanford Works, advantage is being taken of the US experience in conducting a similar, recently completed dose-reconstruction study. In all cases the primary work on dose reconstruction is being performed by scientists from the former Soviet Union. US assistance is in the form of expert consultation and participation, exchange visits, provision of supplies and equipment, and other forms of local assistance

Integrating animals in the classroom: The attitudes and experiences of Australian school teachers toward animal-assisted interventions for children with Autism Spectrum Disorder

Directory of Open Access Journals (Sweden)

Bradley P Smith

2016-02-01

Full Text Available The introduction of animals into school classrooms has been posited as a beneficial intervention for individuals with Autism Spectrum Disorder (ASD. Whilst evidence that animal-assisted interventions or activities can positively influence classroom behaviour and learning outcomes is emerging, little is known about the experiences and attitudes of those who implement it. We presented a series of open and close-ended questions via an online survey to Australian school teachers working with students on the autistic spectrum. Whether teachers had experienced companion animals in the classroom or not, companion animals were believed to provide a means for improving social skills and engagement within the classroom, as well as decreasing stress, anxiety, and the occurrence of problematic behaviours. Yet, despite an overall positive attitude, and 68% having had animals or pets in their classroom, only 16% of respondents had experience with ‘formal’ animal-assisted interventions. Explanations for why both formal and informal animal-assisted interventions were either not being adopted, or was not currently being considered, included a lack of knowledge, lack of support and resources, reactions of the student in relation to allergies and behaviour, and issues relating to animal welfare. It was also acknowledged that the evidence-base for animal-assisted interventions for students with ASD is currently lacking, and that such interventions were not suitable for all students, or all classroom situations. Moving forward, it is important that the inclusion of companion animals and more formal based animal intervention programs in classrooms be adequately designed and evaluated, because implementing or promoting time consuming and financially costly strategies without the evidence is problematic.

Klystron bias power supplies for Indus-2 synchrotron radiation source

Badapanda, M.K.; Hannurkar, P.R.

2008-01-01

The functioning of an alternating current (AC) voltage regulator based high voltage direct current (HVDC) power supplies with better input and output performances has been presented in this paper. The authors have incorporated a 3-phase series limiting inductor, along with detuned passive filter in each power supply, to take care of line harmonics and the input power factor (IPF), which is simple, cost effective, reliable and provides input performance matching that of an equivalent active filter. Such arrangement has special significance for controlled HVDC power supplies supplying to fixed load but operated from widely varying input voltages. It achieves line voltage total harmonic distortion (THD) below 4% and IPF better than 0.97, for 415 V - 30% to 415 V + 10% variations in 3-phase input voltages. A properly designed crowbar, along with suitable limiting elements, is incorporated in each power supply and stringent wire survivability tests were carried out to limit klystron fault energy below 10 Joules. Several simulated waveforms and experiment results are also presented. (author)

The Ventricular Assist Device in the Life of the Child: A Phenomenological Pediatric Study.

Science.gov (United States)

van Manen, Michael A

2017-05-01

What is it like for a child to live with an artificial heart? The use of some medical therapies in children requires developmental considerations, is associated with psychosocial consequences, and calls for ethical sensitivities. A critical case is the ventricular assist device (VAD), a mechanical pump used to support the functioning of a failing heart. As a pediatric therapy, the device can be used as a temporary solution for poor heart function, a bridge to transplantation or recovery, or as a destination therapy. While the mechanical-technical operation of the VAD is well understood, the clinical-technical aspects of young people living with this device are largely unexplored. Drawing on interviews of school-aged children, the aim of this phenomenological study is to explore how a VAD may structure or condition a child's meaningful experience of their world outside the hospital. The driveline of an implanted VAD is the peripheral attachment, extruding through the skin to connect the controller-power supply. The materiality of the device may be interruptive, restrictive, and disturbing to the psycho-physical being and sense of self-identity of the child as a child. And while a child equipped with a VAD is not necessarily conspicuous among other children, the child may experience the device as an exposing presence, while living with the worry of a caregiver who takes on the role not simply of parent but of watchful health professional. A phenomenological understanding of the VAD should assist parents and caregiving health professionals knowing how to deal with specific issues arising in the life of the VAD child.

The development of a laterally confined laboratory fan delta under sediment supply reduction

Zhang, Xiaofeng; Wang, Siqiang; Wu, Xi; Xu, Shun; Li, Zhangyong

2016-03-01

In previous fan delta experiments, the effect of lateral confinement was generally ignored as these fans were usually unconfined with semiconical geometries. However, in gorge areas, fan development is usually laterally confined by valley walls. This study investigates autogenic processes of fan deltas in a laterally confined experimental tank. The experiment is divided into three phases. The sediment supply is held constant within each phase, so the autogenic processes of the fan are separated from the allogenic forcings. Results indicate that laterally confined fan deltas have higher progradation and aggradation potential, more regular channel braiding, and more even transverse sedimentation than unconfined fans. Besides, responses of fan deltas to sediment supply reduction are investigated in this research. At the initiation of the second and third phases, sediment feed rates are instantaneously reduced so that the allogenic forcings are predominant. Observations show that under sediment supply reduction, channelization on fan deltas are more pronounced and durations of the fluvial cycles are longer. The adjustment of fan morphology becomes slower as the self-regulation capacity of the fan decreases with reduced sediment supply.

Explaining regional variation in home care use by demand and supply variables.

2018-02-01

In the Netherlands, home care services like district nursing and personal assistance are provided by private service provider organizations and covered by private health insurance companies which bear legal responsibility for purchasing these services. To improve value for money, their procurement increasingly replaces fee-for-service payments with population based budgets. Setting appropriate population budgets requires adaptation to the legitimate needs of the population, whereas historical costs are likely to be influenced by supply factors as well, not all of which are necessarily legitimate. Our purpose is to explain home care costs in terms of demand and supply factors. This allows for adjusting historical cost patterns when setting population based budgets. Using expenses claims of 60 Dutch municipalities, we analyze eight demand variables and five supply variables with a multiple regression model to explain variance in the number of clients per inhabitant, costs per client and costs per inhabitant. Our models explain 69% of variation in the number of clients per inhabitant, 28% of costs per client and 56% of costs per inhabitant using demand factors. Moreover, we find that supply factors explain an additional 17-23% of variation. Predictors of higher utilization are home care organizations that are integrated with intramural nursing homes, higher competition levels among home care organizations and the availability of complementary services.

Ghost peaks observed after atmospheric pressure matrix-assisted laser desorption/ionization experiments may disclose new ionization mechanism of matrix-assisted hypersonic velocity impact ionization.

Science.gov (United States)

Moskovets, Eugene

2015-08-30

Understanding the mechanisms of matrix-assisted laser desorption/ionization (MALDI) promises improvements in the sensitivity and specificity of many established applications in the field of mass spectrometry. This paper reports a serendipitous observation of a significant ion yield in a post-ionization experiment conducted after the sample had been removed from a standard atmospheric pressure (AP)-MALDI source. This post-ionization is interpreted in terms of collisions of microparticles moving with a hypersonic velocity into a solid surface. Calculations show that the thermal energy released during such collisions is close to that absorbed by the top matrix layer in traditional MALDI. The microparticles, containing both the matrix and analytes, could be detached from a film produced inside the inlet capillary during the sample ablation and accelerated by the flow rushing through the capillary. These observations contribute some new perspective to ion formation in both laser and laser-less matrix-assisted ionization. An AP-MALDI ion source hyphenated with a three-stage high-pressure ion funnel system was utilized for peptide mass analysis. After the laser had been turned off and the MALDI sample removed, ions were detected during a gradual reduction of the background pressure in the first funnel. The constant-rate pressure reduction led to the reproducible appearance of different singly and doubly charged peptide peaks in mass spectra taken a few seconds after the end of the MALDI analysis of a dried-droplet spot. The ion yield as well as the mass range of ions observed with a significant delay after a completion of the primary MALDI analysis depended primarily on the background pressure inside the first funnel. The production of ions in this post-ionization step was exclusively observed during the pressure drop. A lower matrix background and significant increase in relative yield of double-protonated ions are reported. The observations were partially consistent

The graduate assistant athletic trainer (AT) position often serves as one's first experience working independently as an AT and is also an important aspect of the professional socialization process. The socialization experiences of graduate assistant ATs have yet to be fully explored. To understand the socialization process for graduate assistant ATs during their graduate experience. Qualitative study. We conducted phone interviews with all participants. A total of 25 graduate assistant ATs (20 women, 5 men) studying in 1 of 3 academic tracks: (1) accredited postprofessional athletic training program (n = 8), (2) postprofessional athletic training program (n = 11), or (3) a nonathletic training degree program (n = 6). The average age was 25 ± 5 years, and the median age was 24 years. Participants were certified by the Board of Certification for an average of 2 ± 0.4 years. We analyzed the data using a general inductive approach. Peer review, field notes, and intercoder reliability established trustworthiness. Data saturation guided participant recruitment. The ability to gain clinical independence as a practitioner was an important socialization process. Having the chance to develop a relationship with a mentor, who provided support, guidance, and more of a hierarchical relationship, was an important socializing agent for the graduate assistant AT. Participants used the orientation session as a means to understand the expectations and role of the graduate-assistant position. Academic coursework was a way to achieve better inductance into the role via the opportunity to apply classroom skills during their clinical practice. Socializing the graduate assistant blends formal and informal processes. Transition to practice is a critical aspect of the profession; thus, supporting autonomous practice with directed mentoring can promote professional maturity.

This secondary data analysis explored factors influencing job satisfaction in a sample of nursing assistants employed in Maryland skilled nursing facilities. Multiple factors have been shown to affect job satisfaction and turnover in nursing assistants (NAs), but the problem of turnover persists in skilled nursing facility environments affecting quality of care. An existing data set of 556 nursing assistants from 12 Maryland skilled nursing facilities was used. To explore factors found to influence job satisfaction from other studies, a multiple regression analysis was performed. Nine dependent variables previously shown to affect job satisfaction were used. Of these variables, only years of experience (β = .230) and performance of restorative care (β = .095) were found to be positively associated with job satisfaction. Self-esteem (β = -.094) was found to be negatively associated with job satisfaction. Only length of experience and exemplary care as evidenced by the performance of restorative care were associated with job satisfaction. These results mirror results found in other studies. Self-esteem was negatively associated with job satisfaction in this population, a finding needing further study. Copyright © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins

Objective This study was performed to compare the functional and anatomical results of endoscopic-assisted and temporary keratoprosthesis (TKP)-assisted vitrectomy in patients with combat ocular trauma (COT). Methods The medical records of 14 severely injured eyes of 12 patients who underwent endoscopy or TKP implantation in combination with vitreoretinal surgery from 2007 to 2015 were retrospectively evaluated. The patients' ocular history and functional and anatomic anterior and posterior segment results were analyzed. Results Eight eyes (57%) underwent TKP-assisted vitrectomy and six eyes (43%) underwent endoscopic vitrectomy. The most common cause of COT was detonation of improvised explosive devices (72%), and the most common type of injury was an intraocular foreign body (50%). The median time from trauma to surgery and the median surgical time were significantly shorter in the endoscopy than TKP group. The postoperative functional and anatomical results were not significantly different between the two groups. Conclusions TKP-assisted vitrectomy should be performed in eyes requiring extensive bimanual surgery. In such cases, a corneal graft must be preserved for the TKP at the end of the surgery. Endoscopy shortens the surgical time and can reduce the complication rate.

Family members play an important role in the process of writing advance directives. Homosexual men infected with HIV often wish to authorize their intimate same-sex partner or friends rather than immediate family members to make medical decisions on their behalf. Although same-sex marriage is currently illegal in Taiwan, HIV infected homosexual patients are able to write advance directives appointing their same-sex partner to be their surrogate decision maker for end-of-life medical decisions. This case report describes an experience assisting a homosexual patient with HIV to write his advance directives. The nurse assisted the patient and his partner to make a self-determined decision not to resuscitate. Family conferences held to discuss the patient's decisions regarding resuscitation helped legitimize his partner's primary role in making end-of-life healthcare decisions on his behalf. As an advocate for patient rights, nurses should understand the law as it relates to homosexuality and end-of-life decision making, inform patients on the durable power of autonomy, and help execute their advance directives.

Objective: This article endeavours to highlight the evolving nature of the supply chain management (SCM environment, to identify how the two major trends (‘big data’ and analytics will impact SCM in future, to show the benefits that can be derived if these trends are embraced and to make recommendations to supply chain managers. Method: The importance of extracting value from the huge amounts of data available in the SCM area is stated. ‘Big data’ and analytics are defined and the impact of these in various SCM applications clearly illustrated. Results: It is shown, through examples, how the SCM area can be impacted by these new trends and developments. In these examples ‘big data’ analytics have already been embraced, used and implemented successfully. Big data is a reality and using analytics to extract value from the data has the potential to make a huge impact. Conclusion: It is strongly recommended that supply chain managers take note of these two trends, since better use of ‘big data’ analytics can ensure that they keep abreast with developments and changes which can assist in enhancing business competitiveness.

A Multiperiod Supply Chain Network Design Considering Carbon Emissions

Directory of Open Access Journals (Sweden)

Yang Peng

2016-01-01

Full Text Available This paper introduces a mixed integer linear programming formulation for modeling and solving a multiperiod one-stage supply chain distribution network design problem. The model is aimed to minimize two objectives, the total supply chain cost and the greenhouse gas emissions generated mainly by transportation and warehousing operations. The demand forecast is known for the planning horizon and shortage of demand is allowed at a penalty cost. This scenario must satisfy a minimum service level. Two carbon emission regulatory policies are investigated, the tax or carbon credit and the carbon emission cap. Computational experiments are performed to analyze the trade-offs between the total cost of the supply chain, the carbon emission quantity, and both carbon emission regulatory policies. Results demonstrate that for a certain range the carbon credit price incentivizes the reduction of carbon emissions to the environment. On the other hand, modifying the carbon emission cap inside a certain range could lead to significant reductions of carbon emission while not significantly compromising the total cost of the supply chain.

Mashange, Krispen

2002-01-01

Towards the end of the last decade, supplies in petroleum fuel have been erratic to the extent that Zimbabwe has at times operated with as low as 40% of normal supplies. These shortages were attributed mainly to foreign exchange shortages and alleged mismanagement and corruption at the National Oil Company of Zimbabwe (NOCZIM). As shortages intensified, problems of product shortage began to unfold, which adversely impacted on the urban poor. The public began to question the industry's policies on the sustainability of the liquid fuel sector policies in Zimbabwe. Of particular concern was policies regarding regulatory mechanisms, pricing, distribution, utilisation of storage facilities, supply routes and NOCZIM management. This paper evaluates the challenges facing the Zimbabwean petroleum sector and presents recommendations that could assist in ensuring a robust and functional national fuel sector. (Author)

Pal, R.; Sandberg, E.

2017-10-01

This paper explores the inter-organizational value creation, in apparel supply chain context, through circularity and digitalization for sustainability, by gathering evidences from vivid research experiences. It can be highlighted that inter-organizational value creation in both circular- and digital- apparel supply chains largely builds upon a variety of collaborative initiatives, and among a range of included members. Knowledge co-evolvement and business co-development, end-to-end integration and information transfer, and open networks are crucial to such collaborations - making development of new supply chain structures a meta-capability of apparel firms in the changing industrial landscape.

2012-02-01

To report a 6-year multi-institutional experience and outcomes with robot-assisted laparoscopic pyeloplasty (RLP) for the repair of ureteropelvic junction obstruction (UPJO). Between June 2002 and October 2008, 168 adult patients from 3 institutions underwent RLP for UPJO. A retrospective analysis of prospectively collected data were performed after institutional review board approval. Diagnosis was by intravenous urogram or computed tomography scan and diuretic renogram. All patients underwent RLP through a 4-port laparoscopic technique. Demographic, preoperative, operative, and postoperative endpoints for primary and secondary repair of UPJO were measured. Success was defined as a T½ of <20 minutes on diuretic renogram and symptom resolution. Pain resolution was assessed by subjective patient reports. Of 168 patients, 147 (87.5%) had primary repairs and 21 (12.5%) had secondary repairs. Of the secondary repairs, 57% had a crossing vessel etiology. Mean operative time was 134.9 minutes, estimated blood loss was 49 mL, and length of stay was 1.5 days. Mean follow-up was 39 months. Overall, 97.6% of patients had a successful outcome, with a 6.6% overall complication rate. To our knowledge, this review represents the largest multi-institutional experience of RLP with intermediate-term follow-up. RLP is a safe, efficacious, and viable option for either primary or secondary repair of UPJO with reproducible outcomes, a high success rate, and a low incidence of complications.

Hazey, Jeffrey W; Melvin, W Scott

2004-06-01

With the initiation of laparoscopic techniques in general surgery, we have seen a significant expansion of minimally invasive techniques in the last 16 years. More recently, robotic-assisted laparoscopy has moved into the general surgeon's armamentarium to address some of the shortcomings of laparoscopic surgery. AESOP (Computer Motion, Goleta, CA) addressed the issue of visualization as a robotic camera holder. With the introduction of the ZEUS robotic surgical system (Computer Motion), the ability to remotely operate laparoscopic instruments became a reality. US Food and Drug Administration approval in July 2000 of the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA) further defined the ability of a robotic-assist device to address limitations in laparoscopy. This includes a significant improvement in instrument dexterity, dampening of natural hand tremors, three-dimensional visualization, ergonomics, and camera stability. As experience with robotic technology increased and its applications to advanced laparoscopic procedures have become more understood, more procedures have been performed with robotic assistance. Numerous studies have shown equivalent or improved patient outcomes when robotic-assist devices are used. Initially, robotic-assisted laparoscopic cholecystectomy was deemed safe, and now robotics has been shown to be safe in foregut procedures, including Nissen fundoplication, Heller myotomy, gastric banding procedures, and Roux-en-Y gastric bypass. These techniques have been extrapolated to solid-organ procedures (splenectomy, adrenalectomy, and pancreatic surgery) as well as robotic-assisted laparoscopic colectomy. In this chapter, we review the evolution of robotic technology and its applications in general surgical procedures.

Privatization by Other Means: Social Power, Tankers and Techno-Assemblages of Water Supply in Amman, Jordan.

Science.gov (United States)

Mustafa, D.

2016-12-01

Combined piped and tanker based water supply systems have become a ubiquitous feature of urban waterscapes in the global South. Jordanian water sector, and Amman in particular has been a recipient of considerable international financial and technical assistance over the past decades. The international assistance has coupled with the Jordanian state's own pro-market ideological stance, and its political compulsions to spawn a techno-social assemblage of water supply that represents a hybrid state and commercial water supply system. I present the results of a field study in Amman, Jordan on water tankers and water users to understand the techno-political underpinnings of the hybrid system and its impact on differential access to water. I explore how Actor Network Theory (ANT) based analysis of tankers, suction pumps and piped water system and their materiality may explain differential access to water. But that exploration is inflected by a larger political ecological concern with questions of power and discourses about citizenship and claim making on the state. I find that ANT based focus on water technologies, while ontologically fertile, and epistemologically innovative, is nevertheless politically barren. Much richer political insights are to be gained from structural and post-structurally based investigations of the discursive and material drivers of the techno-social assemblages of water supply. The technologies don't just neutrally impact water access, but seem to almost intentionally favour the powerful over the powerless. Surely the political agency must not reside in inanimate technologies but in the social actors and structures that fashion those technologies, and configure them such to reinforce geographies of power. I call for a renewed focus on social power and how its impact on lived geographies is mediated by technology.

Labor supply functions of working male and female pharmacists: In search of the backward bend.

Science.gov (United States)

Carvajal, Manuel J; Deziel, Lisa; Armayor, Graciela M

2012-01-01

Previous research has shown that U.S. pharmacists experience negative elasticities along a backward-bending labor supply function. The presence of a backward bend in the labor supply curve may cause a decrease in the amount of work at a time of labor shortage. Therefore, the determinants of pharmacists' labor supply functions should be explored to assess the impact of this backward bend. To determine whether female and male pharmacist work inputs are influenced by the same factors and estimate where the backward bend occurs, if at all, in their labor supply functions. Data were collected using a survey questionnaire mailed to registered pharmacists in South Florida. Labor supply functions were formulated and tested separately for 558 men and 498 women. The wage rate, other household income, human capital stock, job-related preferences, and opinion variables were hypothesized to explain labor supply differentials. Human capital stock variables included professional experience, holding a specialty board certification, and number of children; job-related preference variables included urban-rural location of work site and main role as a practitioner; and opinion variables included stress, autonomy, fairness in the workplace, flexibility, and job security. Men and women responded differently to identical stimuli, and their supply functions were influenced in different ways by the explanatory variables. Both genders exhibited positive labor supply elasticities greater than those reported in other studies. Both genders' backward bend in their labor supply functions occurred several standard deviations to the right of the mean. The backward bend in the labor supply functions of male and female pharmacists is not likely to affect in the near future the labor market's ability to regulate shortages of practitioners via increases in the wage rate. A more thorough understanding of pharmacists' labor supply functions must address gender issues and differences in response to

DIII-D power supply, design, and development

Nerem, A.

1995-02-01

An overview of the DIII-D power supply system with information details concerning the configuration, power ratings, acquisition costs, and cost scaling relevant to the design of ITER and other tokamaks is presented. The power supplies for the DIII-D tokamak were installed and commissioned during the late 1970's and the beginning of the 1980's. Several upgrades have been implemented during the last two years to solve increasing reliability problems encountered as the equipment aged, to provide enhanced operational flexibilities, and to enable operation at the higher power levels needed to provide experimental data relevant to the ITER and TPX design activities. These upgrades ranged from redesign of the power supply control systems to the replacement of vacuum circuit breakers which had become unreliable in service. A new interlock and protection system has also been implemented using the latest programmable logic controllers (PLC) and computer technology. These upgrades have been highly successful and are described to provide insight to many issues in the specification of high power converters. Power supply models used in the design of the DIII-D Plasma Control System are also described along with model verification test data. These models are being used in the development of a new advanced plasma control system for the DIII-D tokamak. Recent operational experience and results are presented

Background The aim of this study was to evaluate the indications, safety, feasibility, and short- and long-term outcomes for elderly patients who underwent robot-assisted middle pancreatectomies (MPs). Material/Methods Ten patients (≥60 years) underwent robot-assisted middle pancreatectomies from 2012 to 2015. The perioperative data, including tumor size, operating time, rate of postoperative pancreatic fistula (POPF), postoperative morbidity, and other parameters, were analyzed. We collected and analyzed the follow-up information. Results The mean age of patients was 64.30 years (range, 60–73 years). The average tumor size was 2.61 cm. The 10 cases were all benign or low-grade malignant lesions. The mean operating time was 175.00 min. The mean blood loss was 113.00 ml with no blood transfusion needed. Postoperative fistulas developed in 5 patients; there were 2 Grade A fistulas and 3 grade B fistulas. There were 3 patients who underwent postoperative complications, including 2 Grade 1 or 2 complications and 1 Grade 3 complication. No reoperation and postoperative mortality occurred. The mean hospital stay was 19.91 days. After a median follow-up of 23 months, new onset of diabetes mellitus developed in 1 patient and none suffered from deterioration of previously diagnosed diabetes or exocrine insufficiency, and no tumor recurrence happened. Conclusions Robot-assisted middle pancreatectomy was safe and feasible for elderly people. It had low risk of exocrine or endocrine dysfunction and benefited patients’ long-term outcomes. Incidence of POPF was relatively high but we could prevent it from resulting in bad outcomes by scientific perioperative care and systemic treatment. PMID:26395335

Context: The graduate assistant athletic trainer (AT) position often serves as one's first experience working independently as an AT and is also an important aspect of the professional socialization process. The socialization experiences of graduate assistant ATs have yet to be fully explored. Objective: To understand the socialization process for graduate assistant ATs during their graduate experience. Design: Qualitative study. Setting: We conducted phone interviews with all participants. Patients or Other Participants: A total of 25 graduate assistant ATs (20 women, 5 men) studying in 1 of 3 academic tracks: (1) accredited postprofessional athletic training program (n = 8), (2) postprofessional athletic training program (n = 11), or (3) a nonathletic training degree program (n = 6). The average age was 25 ± 5 years, and the median age was 24 years. Participants were certified by the Board of Certification for an average of 2 ± 0.4 years. Data Collection and Analysis: We analyzed the data using a general inductive approach. Peer review, field notes, and intercoder reliability established trustworthiness. Data saturation guided participant recruitment. Results: The ability to gain clinical independence as a practitioner was an important socialization process. Having the chance to develop a relationship with a mentor, who provided support, guidance, and more of a hierarchical relationship, was an important socializing agent for the graduate assistant AT. Participants used the orientation session as a means to understand the expectations and role of the graduate-assistant position. Academic coursework was a way to achieve better inductance into the role via the opportunity to apply classroom skills during their clinical practice. Conclusions: Socializing the graduate assistant blends formal and informal processes. Transition to practice is a critical aspect of the profession; thus, supporting autonomous practice with directed mentoring can promote professional

Takeda, Syohei; Sato, Yasuhiro; Kiyama, Satoru; Ikeda, Nagayasu

1986-01-01

The ETL-TPE2 experiment is planned to investigate a behavior of high beta plasma with high temperature. A system design of power supply to generate and to confine the plasma is described. Essential features of the design are the following; 1) To obtain a dense plasma with high temperature, two capacitor banks with opposite polarities of 80 kV charging voltage are provided in tandem feed for the toroidal fast field. 2) A high current pulse with long duration is supplied by a power crowbar system and realizes the investigation of the plasma confinement for a longer pulsed magnetic field. A power supply system of the power crowbar is connected with a main circuit in series through a current transformer. The circuit system is operated at high efficiency and high reliability. 3) In the vertical and compensating field circuits, each rise time and peak value of currents can be controlled over a wide range of pre-set programmings corresponding to an experimental condition. 4) A small resistance is connected with a crowbar circuit in a compression pre-heat field circuit. The circuit can be crowbarred at an arbitrary phase. This operation and the effect of additional resistance are favourable to maintain an effective plasma heating and to improve the plasma confinement. (author)

Quality Improvement Policies in a Supply Chain with Stackelberg Games

2014-01-01

Full Text Available We first analyze quality and price decisions in a supply chain with two Stackelberg games: Manufacturer’s Stackelberg (MS and Supplier’s Stackelberg (SS. Then, we investigate how equilibrium solutions are influenced by proposed quality improvement policies: coordination and manufacturer’s involvement. Also, we derive the conditions under which the policies can be implemented in both MS and SS strategies. Numerical experiments illustrate the problems and several related issues are discussed. The results suggest that proposed quality improvement policies can realize Pareto improvement for the supply chain performance.

Integral evaluation of energy supply systems at mountain refuges

Most of the mountain refuges scattered over the Alps (more than 1500) are not connected to public infrastructure, requiring decentralized supply and disposal and are therefore called island systems. The increasing number of guests goes along with a higher demand for comport and thus puts pressure on available resources. There are numerous challenges like remoteness, transport, low temperatures, seasonal operation and climate change to be faced. Furthermore, the supply and disposal system of an alpine hut has to merge different interests of the alpine associations, refuge operators, legal authorities and the alpine tourists. Therefore the respective infracstructure has to be managed as an overall-self-contained system. Energy supply is the central issue showing complex interaction with water supply, wastewater treatment and waste disposal. Many problems according to planning, decision-making, construction and operation concerning alpine infrastructure are reported. However detailed information on experiences made in these fields is missing at an international level so far. To correct this lack of data, the German Alpine Association (DAV) initiated the project ''Integral Evaluation of Supply and Disposal Systems of Mountain Refuges, IEVEBS'' in 2006, inviting all stakeholders (Alpine Associations, Legal Authorities, Planners, and Researchers) to participate. Additionally to the final project report which contains a detailed description and evaluation of the supply systems, guidelines will be elaborated in 2010 for planning, implementation and operation, all applicable at an international level.

Elgueta, M. A.; Hassan, M. A.; von Flotow, C. M.

2012-12-01

Sediment supply is a key controlling factor in bed morphology and sediment mobility. Under a low supply regime, bed structuring develops and reduces sediment mobility. Under high supply, structuring is suppressed and the bed exhibits patchiness. This study examines the spatial response of a mountain stream channel to changes in the sediment supply regime. To achieve this goal, a flume experiment was conducted in the Mountain Channel Hydraulic Experimental Laboratory at the University of British Columbia. An 18 meter long, one meter wide flume, with a slope of three percent was used. Seven continuous runs were conducted. Each of them lasted 40 hours, under constant flow and different sediment supply regimes, which included no feed, constant feed and episodic supply. In each run, bed elevation, bed grain size distribution, flow resistance, sediment mobility and degree of armoring were determined. Flume results were compared to field data from a 600 meter channel reach that exhibits rapid, riffle-pool and step-pool morphology in UBC Malcolm Knapp Research Forest. The study gave the possibility to analyze in detail the spatial adjustment of a mountain channel to changes in the sediment supply regime, including episodic inputs.

The AMS-02 Tracker power supply system, described in this paper, has been designed optimizing noise performances, modularity and efficiency. The power is distributed starting from a 28V line coming from the power distribution system is converted into the needed voltages by means of DC-DC converters, and for bias supply and front-end voltages is post-regulated by means of linear regulators. Components Off The Shelf (COTS) have been extensively used in the construction of this power supply, however various radiation test campaigns have been performed in order to verify the reliability of these components. The power supply architecture developed for the tracker detector has been used as a guideline for the development of the power supplies for the other detectors in the experiment

Fairweather, Glenn C; Lincoln, Michelle A; Ramsden, Robyn

2017-01-01

Difficulties in accessing allied health services, especially in rural and remote areas, appear to be driving the use of telehealth services to children in schools. The objectives of this study were to investigate the experiences and views of school executive staff and therapy assistants regarding the feasibility and acceptability of a speech-language pathology telehealth program for children attending schools in rural and remote New South Wales, Australia. The program, called Come N See, provided therapy interventions remotely via low-bandwidth videoconferencing, with email follow-up. Over a 12-week period, children were offered therapy blocks of six fortnightly sessions, each lasting a maximum of 30 minutes. School executives (n=5) and therapy assistants (n=6) described factors that promoted or threatened the program's feasibility and acceptability, during semistructured interviews. Thematic content analysis with constant comparison was applied to the transcribed interviews to identify relationships in the data. Emergent themes related to (a) unmet speech pathology needs, (b) building relationships, (c) telehealth's advantages, (d) telehealth's disadvantages, (e) anxiety replaced by joy and confidence in growing skills, and (f) supports. School executive staff and therapy assistants verified that the delivery of the school-based telehealth service was feasible and acceptable. However, the participants saw significant opportunities to enhance this acceptability through building into the program stronger working relationships and supports for stakeholders. These findings are important for the future development of allied health telehealth programs that are sustainable as well as effective and fit the needs of all crucial stakeholders. The results have significant implications for speech pathology clinical practice relating to technology, program planning and teamwork within telehealth programs.

1999-01-01

This paper discusses US natural gas supply dynamics in the context of the North American gas marketplace. Supply fundamentals are examined, methodology is briefly presented, regional supply outlooks are discussed. Assumptions, drivers and issues are highlighted. The analysis and outlook indicate that the sizeable North American resource base can be economically developed to supply growing US natural gas requirements. The major incremental supply sources are likely to come from deepwater Gulf of Mexico, Rocky Mountain regions, onshore Texas and imports from Canada. Given this outlook, major business and investment opportunities exist for the gas upstream and midstream sectors despite some short-term challenges

A dual V t disturb-free subthreshold SRAM with write-assist and read isolation

Bhatnagar, Vipul; Kumar, Pradeep; Pandey, Neeta; Pandey, Sujata

2018-02-01

This paper presents a new dual V t 8T SRAM cell having single bit-line read and write, in addition to Write Assist and Read Isolation (WARI). Also a faster write back scheme is proposed for the half selected cells. A high V t device is used for interrupting the supply to one of the inverters for weakening the feedback loop for assisted write. The proposed cell provides an improved read static noise margin (RSNM) due to the bit-line isolation during the read. Static noise margins for data read (RSNM), write (WSNM), read delay, write delay, data retention voltage (DRV), leakage and average powers have been calculated. The proposed cell was found to operate properly at a supply voltage as small as 0.41 V. A new write back scheme has been suggested for half-selected cells, which uses a single NMOS access device and provides reduced delay, pulse timing hardware requirements and power consumption. The proposed new WARI 8T cell shows better performance in terms of easier write, improved read noise margin, reduced leakage power, and less delay as compared to the existing schemes that have been available so far. It was also observed that with proper adjustment of the cell ratio the supply voltage can further be reduced to 0.2 V.

Full Text Available Supply chain is a network of organizations that work together and performs various business functions such as procurement of raw materials, converting the raw material into semi-finished or finished goods and distributing the same to their ultimate customers. Presence of bullwhip effect in a supply chain is costly and degrades the performance of the supply chain. Reduction in bullwhip effect can improve the efficiency or profitability of a supply chain. The objective of this paper is to know the impact of imperfect Advance Demand Information (ADI sharing on bullwhip effect in a four-stage serial supply chain and to evaluate the supply chain performance by conducting an experiment similar to the beer distribution game. The performance measures used are variance of orders placed by each stage, fill rate, total inventory at each stage and total holding cost of the supply chain. Results show that imperfect ADI improves the performance of the supply chain. The performance of the supply chain is also evaluated under order up to level (R, S policy with safety stock and it is found that the performance of supply chain is better when inventory policy used.
