    The cost benefits have been demonstrated for an integrated program, which is currently being implemented for two PWR stations with two 1100-MW units each. The component classification efforts reduced the number of safety-related components in several systems. Furthermore, the knowledge of the component specific function has contributed to the reduction of many safety-related parts per component, in addition to ensuring the procurement of parts to the correct safety level. The use of qualified commercial grade parts and components with their lower cost and reasonable procurement lead time compared to their 10 CFR 21 counterparts has a pronounced economic effect on the utility balance sheets

    1987-01-01

    Throughout construction, testing, and commercial operation of a nuclear power plant, utilities have a need for spare parts and consumables that must meet a wide range of technical and quality assurance (QA) requirements. The applications for which parts and consumables may be used need to be identified prior to procurement to ensure that the design basis of the plant is not compromised. The spare parts program at Shearon Harris nuclear power plant supported the maintenance department with the proper parts when needed for all but 5% of the maintenance work requests

    As is fairly common with new reactor facilities, we had a few spare parts on hand as part of our original purchase when the OSU TRIGA first went critical in March of 1967. Within a year or so, however, it became apparent that we should critically examine our spare parts inventory in order to avoid unnecessary or prolonged outages due to lack of a crucial piece of equipment. Many critical components (those which must be present and operable according to our license or technical specifications) were considered, and a priority list of acquiring these was established. This first list was drawn up in March, 1969, two years after initial criticality, and some key components were ordered. The availability of funds was the overriding restriction then and now. This spare-parts list is reviewed and new components purchased annually; the average amount spent has been about $2,000 per year. This inventory has proved invaluable more than once; without it, we would have had lengthy shutdowns awaiting the arrival of the needed component. The sobering thought, however, is that our spare-parts inventory is still not complete-far from it, in fact, because this would be prohibitively expensive. It is very difficult to guess with 100% accuracy just which component might need replacing, and your $10,000 inventory of spare parts is useless in that instance if it doesn't include the needed part. An idea worth considering is to either (a) encourage General Atomic, through the collective voice of all TRIGA owners, to maintain a rather complete inventory of replacement parts, or (b) maintain an owner's spare-parts pool, financed by contributions from all the facilities. If either of these pools was established, the needed part could reach any facility within the U.S. within a few days, minimizing reactor outage time. (author)

    During Fiscal Year 2012, a team from the Pacific Northwest National Laboratory (PNNL) conducted an assessment and analysis of the Second Line of Defense (SLD) Sustainability spare parts program. Spare parts management touches many aspects of the SLD Sustainability Program including contracting and integration of Local Maintenance Providers (LMP), equipment vendors, analyses and metrics on program performance, system state of health, and maintenance practices. Standardized spares management will provide better data for decisions during site transition phase and will facilitate transition to host country sustainability ownership. The effort was coordinated with related SLD Sustainability Program initiatives, including a configuration items baselining initiative, a metrics initiative, and a maintenance initiative. The spares study has also led to pilot programs for sourcing alternatives that include regional intermediate inventories and partnering agreements that leverage existing supply chains. Many partners from the SLD Sustainability program contributed to and were consulted in the course of the study. This document provides a description of the findings, recommendations, and implemented solutions that have resulted from the study.

    Inventory control of spare parts plays an increasingly important role in operation management. The trade-off is clear: on one hand a large number of spare parts ties up a large amount of capital, while on the other hand too little inventory may result in extremely costly emergency actions. This is why during the last few decades inventory of spare parts control has been the topics of many publications. Recently management systems such as manufacturing resources planning (MRP) and enterprise resource planning (ERP) have been added. However, most of these contributions have similar theoretical background. This means the concepts and techniques are mainly based on mathematical assumptions and modeling inventory of spare parts situations Nuclear utilities in Korea have several problems to manage the optimum level of spare parts though they used MRP System. Because most of items have long lead time and they are imported from United States, Canada, France and so on. In this paper, we will examine the available inventory optimization models which are applicable to nuclear power plant and then select optimum model and assumptions to make inventory of spare parts strategies. Then we develop the computer program to select and determine optimum level of spare parts which should be automatically controlled by KHNP ERP system. The main contribution of this paper is an inventory of spare parts control model development, which can be applied to nuclear power plants in Korea.

    In this research, we consider the spares provisioning problem, where a finite population of homogeneous machines are being deployed to meet a constant demand. While a machine is operating, it could become inoperable due to the failure of a critical built-in part in the machine. Before repairs on the machine can be initiated, however, a replacement part must be obtained. If a replacement part is available from stock, the machine is immediately transferred to the repair subsystem...

    The Office of the Second Line of Defense (SLD) is part of the Department of Energy‘s (DOE) National Nuclear Security Administration (NNSA). The SLD Program accomplishes its critical global security mission by forming cooperative relationships with partner countries to install passive radiation detection systems that augment traditional inspection and law enforcement measures by alerting border officials to the presence of special nuclear or other radiological materials in cross-border traffic. An important tenet of the program is to work collaboratively with these countries to establish the necessary processes, procedures, infrastructure and conditions that will enable them to fully assume the financial and technical responsibilities for operating the equipment. As the number of operational deployments grows, the SLD Program faces an increasingly complex logistics process to promote the timely and efficient supply of spare parts.

  17. Stochastic model of forecasting spare parts demand

    2012-01-01

    hypothesis of the existence of phenomenon change trends, the next step in the methodology of forecasting is the determination of a specific growth curve that describes the regularity of the development in time. These curves of growth are obtained by the analytical representation (expression of dynamic lines. There are two basic stages in the process of expression and they are: - The choice of the type of curve the shape of which corresponds to the character of the dynamic order variation - the determination of the number of values (evaluation of the curve parameters. The most widespread method of forecasting is the trend extrapolation. The basis of the trend extrapolation is the continuing of past trends in the future. The simplicity of the trend extrapolation process, on the one hand, and the absence of other information on the other hand, are the main reasons why the trend extrapolation is used for forecasting. The trend extrapolation is founded on the following assumptions: - The phenomenon development can be presented as an evolutionary trajectory or trend, - General conditions that influenced the trend development in the past will not undergo substantial changes in the future. Spare parts demand forecasting is constantly being done in all warehouses, workshops, and at all levels. Without demand forecasting, neither planning nor decision making can be done. Demand forecasting is the input for determining the level of reserve, size of the order, ordering cycles, etc. The question that arises is the one of the reliability and accuracy of a forecast and its effects. Forecasting 'by feeling' is not to be dismissed if there is nothing better, but in this case, one must be prepared for forecasting failures that cause unnecessary accumulation of certain spare parts, and also a chronic shortage of other spare parts. All this significantly increases costs and does not provide a satisfactory supply of spare parts. The main problem of the application of this model is that each

    This paper describes an expert system which can handle spare part requirements not only in corrective maintenance (CM) or preventive maintenance (PM), but also when failure rates of components or parts are updated by new data or by predictive maintenance (PDM), and which can also decide optimum stocking level of each spare part. This expert system provides a maintenance (or inventory) manager with an improved basis for decision making in the maintenance related to spare parts. The definitions of PM and PDM from NUREG-1212 (USNRC 1986) are used herein. This expert system used Intellignece/Compiler (Intelligence Ware, 1986) as a language/tool in the IBM-PC

  2. Joint optimization of redundancy level and spare part inventories

    Sleptchenko, Andrei; Heijden, Matthieu van der

    2016-01-01

    We consider a “k-out-of-N” system with different standby modes. Each of the N components consists of multiple part types. Upon failure, a component can be repaired within a certain time by switching the failed part by a spare, if available. We develop both an exact and a fast approximate analysis to compute the system availability. Next, we jointly optimize the component redundancy level with the inventories of the various spare parts. We find that our approximations are very accurate and suitable for large systems. We apply our model to a case study at a public organization in Qatar, and find that we can improve the availability-to-cost ratio by reducing the redundancy level and increasing the spare part inventories. In general, high redundancy levels appear to be useful only when components are relatively cheap and part replacement times are high. - Highlights: • We analyze a redundant system (k-out-of-N) with multiple parts and spares. • We jointly optimize the redundancy level and the spare part inventories. • We develop an exact method and an approximation to evaluate the system availability. • Adding spare parts and reducing the redundancy level cuts cost by 50% in a case study. • The availability is not very sensitive to the shape of the failure time distribution.

  4. Model of delivery consolidation of critical spare part : case study of an oil and gas company

    Science.gov (United States)

    Hartanto, D.; Agustinita, A.

    2018-04-01

    The availability of spare parts in oil and gas industry is very important to prevent the occurrence of very high opportunity cost, that is the loss caused by exploitation equipment which must stop because of unavailability of the spare part. This is done by providing safety stock with a very high service level that leads to high inventory costs. If the company wants to lower inventory costs, the choices are not to lower the service level but to lower the ordering cost. One of the components of ordering cost is the delivery cost. Exploitation facilities are usually located in remote areas so that the cost of delivery is high. In addition, many spare parts are supplied by the same supplier. Therefore, there is an opportunity to lower the cost of delivery of spare parts by consolidation. In this paper,mixed integer linear programming (MILP) model is developed to plan the procurement of spare parts so that inventory costs which include holding and ordering cost for spare parts can be minimized. The model has been verified and validated. Using this model the company can lower inventory costs of the spare part by 32%.

    This paper presents a 0–1 programming model aimed at obtaining the optimal inventory policy and transportation mode for maintenance spare parts of high-speed trains. To obtain the model parameters for occasionally-replaced spare parts, a demand estimation method based on the maintenance strategies of China’s high-speed railway system is proposed. In addition, we analyse the shortage time using PERT, and then calculate the unit time shortage cost from the viewpoint of train operation revenue. Finally, a real-world case study from Shanghai Depot is conducted to demonstrate our method. Computational results offer an effective and efficient decision support for inventory managers.

    Full Text Available Effective and efficient inventory management is the key to the economic sustainability of capital intensive modern industries. Inventory grows exponentially with complexity and size of the equipment fleet. Substantial amount of capital is required for maintaining an inventory and therefore its optimization is beneficial for smooth operation of the project at minimum cost of inventory. The size and hence the cost of the inventory is influenced by a large no of factors. This makes the optimization problem complex. This work presents a model to solve the problem of optimization of spare parts inventory. The novelty of this study lies with the fact that the developed method could tackle not only the artificial test case but also a real-world industrial problem. Various investigators developed several methods and semi-analytical tools for obtaining optimum solutions for this problem. In this study non-traditional optimization tool namely genetic algorithms GA are utilized. Apart from this Coxs regression analysis is also used to incorporate the effect of some environmental factors on the demand of spares. It shows the efficacy of the applicability of non-traditional optimization tool like GA to solve these problems. This research illustrates the proposed model with the analysis of data taken from a fleet of dumper operated in a large surface coal mine. The optimum time schedules so suggested by this GA-based model are found to be cost effective. A sensitivity analysis is also conducted for this industrial problem. Objective function is developed and the factors like the effect of season and production pressure overloading towards financial year-ending is included in the equations. Statistical analysis of the collected operational and performance data were carried out with the help of Easy-Fit Ver-5.5.The analysis gives the shape and scale parameter of theoretical Weibull distribution.

    Spare parts, especially safety related items, being used in Korea Nuclear Power Plants are largely from the United States, Canada, France and the like, meaning the inventory policy, stocking and provision, should be influenced by those countries' nuclear industry situation in a direct or indirect manner. As a result of nuclear industry downturn practices, lots of spare supply corporations have gone broke, which gave immediate signals we have to resolve inventory purchases in need. It is known for that nuclear maintenance spare items are particularly composed of many kinds with small quantities, which makes matters worse to Korea nuclear operation company (KHNP) to purchase them. Hence, Korea nuclear business is trying to change its exinventory purchasing paradigm into innovative schemes it did not have to consider in the past. In order to implement a new stocking policy, it should be kept in mind the factors such as not only how much to stock for a smooth operation but also economic point of view. Even though it has done a lot of studies to optimize the inventory stocking level in an academic curiosity, it is not easy to apply the researches in a real world. Since it is so tough job to anticipate when and how large scale even occurs. Hence, it would be thought that the nuclear inventory should be dealt in a different manner from the general manufacturing industry

In order to minimize the cost of delay caused by unexpected failure, Genetic algorithms (GAs are used to allocate the initial quantity of parts among the airports. GAs are a class of adaptive search procedures, that distinguish themselves from other optimization techniques by the use of concepts from population genetics to guide the search. Problem-specific knowledge is incorporated into the problem and efficient parameters are identified and tested for the task of optimizing the allocation of parts. The approach is illustrated by numerical results.

    Electricity distribution companies are required to improve their operational cost effectiveness. The storage systems of the companies have traditionally been based on the 'adequate' number of stores with plenty of different components. Therefore, they are potential objects for cost reduction. The effective operation of spare part management of an electricity distribution network requires that the spare components can be delivered at the fault site quickly in order to avoid excessive outage costs. In a fault situation the stores form a net structure. Currently the rural electricity distribution companies lack suitable methods for designing a spare part storage system. This thesis presents a suitable method for the designing problem. The models assume that faults of a distribution network are stochastic. Therefore, they are best suited for component types installed in large quantities. Improved methods for defining the outage, material and total costs for perpetual order quantity and periodic order-up-to-level storage control systems are described. The method for determining the control parameters of the stores is also presented and ways for finding the necessary initial parameter values are introduced. The developed method is tested in Haemeen Saehko Oy (HSOY). The results of the calculations are given. The key findings are: Small differences in the designing results can increase costs remarkably. For example, in HSOY too low stock levels can result in even eight folds higher outage costs than in the proper design. The best number of stores is not the same for all component types. For example, in HSOY the best number of stores is seven for the 50 kVA transformers and one for the 315 kVA transformers in a summer. If the stock levels are increased the protection against the demand variations is the better the shorter the duration of the review period and/or the replenishment lead time is. (orig.)

    We address a problem of inventory management of spare parts in the context of a large energy company, producer of oil and gas. Spare parts are critical for assuring operational conditions in offshore platforms. About 200,000 different items are held in several inventory plants. The inventory system implemented at the company corresponds to a min-max system. The control parameters are decided based mainly on the expert judgment of the planners. Also, though the inventory plants can in practice be supplied from each other, the inventory planning is performed separately by the plant planners. This is because of different ownership structures where the studied company has the operative responsibility. The company is pursuing a system in which all planners conform to the same inventory management approach and evaluation, as well as being more cost efficient. Our work focuses on supporting this goal. We apply methods to decide the inventory control parameters for this system under a service level constraint. The methodology we use distinguishes unit-size and lot-size demand cases. We perform computational experiments to find control parameters for a sample of items. After the control parameters are found, we use them to explore the impact of risk pooling among the plants and inaccuracy arising from duplicate item codes.(Author)

    Full Text Available Knowing the demand of spare parts is the basis for successful spare parts inventory management. Inventory management has two aspects. The first one is operational management: acting according to certain models and making decisions in specific situations which could not have been foreseen or have not been encompassed by models. The second aspect is optimization of the model parameters by means of inventory management. Supply items demand (asset demand is the expression of customers' needs in units in the desired time and it is one of the most important parameters in the inventory management. The basic task of the supply system is demand fulfillment. In practice, demand is expressed through requisition or request. Given the conditions in which inventory management is considered, demand can be: - deterministic or stochastic, - stationary or nonstationary, - continuous or discrete, - satisfied or unsatisfied. The application of the maintenance concept is determined by the technological level of development of the assets being maintained. For example, it is hard to imagine that the concept of self-maintenance can be applied to assets developed and put into use 50 or 60 years ago. Even less complex concepts cannot be applied to those vehicles that only have indicators of engine temperature - those that react only when the engine is overheated. This means that the maintenance concepts that can be applied are the traditional preventive maintenance and the corrective maintenance. In order to be applied in a real system, modeling and simulation methods require a completely regulated system and that is not the case with this spare parts supply system. Therefore, this method, which also enables the model development, cannot be applied. Deterministic models of forecasting are almost exclusively related to the concept of preventive maintenance. Maintenance procedures are planned in advance, in accordance with exploitation and time resources. Since the timing

    With deregulation, utilities in the power sector face a much more urgent imperative to emphasize cost efficiencies as compared to the days of regulation. One major opportunity for cost savings is through reductions in spare parts inventories. Most utilities are accustomed to carrying large volumes of expensive, relatively slow-moving parts because of a high degree of risk-averseness. This attitude towards risk is rooted in the days of regulation. Under regulation, companies recovered capital inventory costs by incorporating them into the base rate charged to their customers. In a deregulated environment, cost recovery is no longer guaranteed. Companies must therefore reexamine their risk profile and develop policies for spare parts inventory that are appropriate for a competitive business environment. This research studies the spare parts inventory management problem in the context of electric utilities, with a focus on nuclear power. It addresses three issues related to this problem: criticality, risk, and policy. With respect to criticality and risk, a methodology is presented that incorporates the use of influence diagrams and the Analytic Hierarchy Process (AHP). A new method is developed for group aggregation in the AHP when Saaty and Vargas' (2007) dispersion test fails and decision makers are unwilling or unable to revise their judgments. With respect to policy, a quantitative model that ranks the importance of keeping a part in inventory and recommends a corresponding stocking policy through the use of numerical simulation is developed. This methodology and its corresponding models will enable utilities that have transitioned from a regulated to a deregulated environment become more competitive in their operations while maintaining safety and reliability standards. Furthermore, the methodology developed is general enough so that other utility plants, especially those in the nuclear sector, will be able to use this approach. In addition to regulated

    The objective of a spare part support operation is to fulfill the part request order with different service contracts in the agreed response time. With this objective to achieve different service targets for multiple service contracts and the considerations of inventory investment, it is not only important to determine the inventory policy but also to design the structure of inventory pools and the order fulfilment strategies. In this research, we focused on two types of inventory pools: multiple inventory pool (MIP) and consolidated inventory pool (CIP). The idea of MIP is to maintain separated inventory pools based on the types of service contract, while CIP solely maintains a single inventory pool regardless of service contract. Our research aims to design the inventory pool analytically and propose reserve strategies to manage the order fulfilment risks in CIP. Mathematical models and simulation experiments would be applied for analysis and evaluation.

    The management of spare parts is a major concern for several industrial organizations, due to the significant amount of resources invested every year for holding spares inventories. In this paper, we explore the possibility of using genetic algorithms for the task of optimizing the number of spare parts required by a multi-component system. To address the question of how many spares should be kept in inventory for each component kind, the analyst is required to define objective functions with respect to which the optimization is sought. In our work we will look at multiple objectives such as, for example, the maximization of system revenues and the minimization of the total spares volume. The modeling of the system failure, repair and replacement stochastic processes is done by means of Monte Carlo simulation, whose flexibility allows a closer adherence to reality

    Asset-intensive companies face great pressure to reduce operation costs and increase utilization. This scenario often leads to over-stress on critical equipment and its spare parts associated, affecting availability, reliability, and system performance. As these resources impact considerably on financial and operational structures, the opportunity is given by demand for decision-making methods for the management of spare parts processes. We proposed an ordering decision-aid technique which uses a measurement of spare performance, based on the stress–strength interference theory; which we have called Condition-Based Service Level (CBSL). We focus on Condition Managed Critical Spares (CMS), namely, spares which are expensive, highly reliable, with higher lead times, and are not available in store. As a mitigation measure, CMS are under condition monitoring. The aim of the paper is orienting the decision time for CMS ordering or just continuing the operation. The paper presents a graphic technique which considers a rule for decision based on both condition-based reliability function and a stochastic/fixed lead time. For the stochastic lead time case, results show that technique is effective to determine the time when the system operation is reliable and can withstand the lead time variability, satisfying a desired service level. Additionally, for the constant lead time case, the technique helps to define insurance spares. In conclusion, presented ordering decision rule is useful to asset managers for enhancing the operational continuity affected by spare parts

    Purpose: This manuscript explores the link between Spare Parts Management and Total Costs of Ownership or Life Cycle Costs (LCC). Design/methodology/approach: First, this work enumerates the different managerial decisions instances in spare parts management that are present during the life cycle of a physical asset. Second, we analyse how those decision instances could affect the TCO of a physical asset (from the economic point of view). Finally, we propose a conceptual framework for incorporating the spare parts management into a TCO model. Findings: The recent literature lacks discussions on the integration of spare parts management with the Total Costs of Ownership (TCO). Based in an extensive literature revision we can declare that the computation of costs related to spare parts management has been neglected by TCO models. Originality/value: The contribution of this paper is twofold. First, a literature review and identification of a series of spare parts management decision instances and its relationship with TCOs is presented in this paper. Second, a conceptual framework is suggested for linking those decisions instances to a total cost of ownership perspective. Some research questions and future research challenges are presented at the end of this work.

    Full Text Available The life spans of durable goods are longer than their warranty periods. To satisfy the service demand of spare parts and keep the market competition advantage, enterprises have to maintain the longer inventory planning of spare parts. However, how to obtain a valid number of spare parts is difficult for those enterprises. In this paper, we consider a spare-part inventory problem, where the inventory can be replenished by two ways including the final production order and the remanufacturing way. Especially for the remanufacturing way, we consider the acquisition management problem of used products concerning an acquisition pricing decision. In a multiperiod setting, we formulate the problem into a dynamic optimization problem, where the system decisions include the final production order and acquisition price of used products at each period. By stochastic dynamic programming, we obtain the optimal policy of the acquisition pricing at each period and give the optimal policy structure of the optimization problem at the first period. Then, a recursion algorithm is designed to calculate the optimal decisions and the critical points in the policy. Finally, the numerical analyses show the effects of demand information and customer’s sensitive degree on the related decisions and the optimal cost.

    Spare part procurement is a complex issue and requires an accurate analysis. Stock outs of spare part can leads a great impact on production. Therefore, it is necessary to design the inventory control of spare parts that guarantee the availability of spare parts needed for supporting the maintenance activity. This paper studies the inventory policy for sewing machine spare part using hazard function to approximate the demand. Hazard function is the indicator of the effect of ageing on the reliability of the system. It quantifies the risk of failure as the age of the system increases. We use a continuous review policy based on Hadley Within Approach to calculate the optimum inventory level for critical spare parts. There are four spare parts categorized as critical spare parts, which are needle plate, feed dog, rotary and binder attachment. The optimal ordering quantity for needle plate, feed, rotary and binder attachment are 5 units, 17 units, 5 units, and 9 units, respectively and the reorder point are 2 units, 1 unit, 2 units and 1 unit, respectively. Finally, the service level achieved by the proposed policy is in a range of 95.91%-97.93%, which indicates that the inventory level of spare parts can be used to support the required parts in the maintenance activity.

TECNATOM it's made up of highly qualified specialists with an extensive experience and dedicated spirit and a pool of young people who interact with them to ensure the continuity of the company as a great team. As an important part of our activities, the 'Spares Engineering', complements the reliability and guarantee of a committed company. Nowadays, because of different reasons, there is a growing problematic in the collection of safety equipment and its spares in the NPPs. Tecnatom has set several actions in motion directed to improve the availability of these equipment and spares, by means of life extension of equipment installed, by means of the development of equipment and spares alternatives to the originals, or by means of services in relation with the spare parts. The actions developed until now have provided satisfactory results in technical and economical terms for the Plants. We have developments at present in course, that we hope they will increase this contribution to solve the problems of obsolescence in NPP's. (authors)

  4. A joint spare part and maintenance inspection optimisation model using the Delay-Time concept

    2011-01-01

    Spare parts and maintenance are closely related logistics activities where maintenance generates the need for spare parts. When preventive maintenance is present, it may need more spare parts at one time because of the planned preventive maintenance activities. This paper considers the joint optimisation of three decision variables, e.g., the ordering quantity, ordering interval and inspection interval. The model is constructed using the well-known Delay-Time concept where the failure process is divided into a two-stage process. The objective function is the long run expected cost per unit time in terms of the three decision variables to be optimised. Here we use a block-based inspection policy where all components are inspected at the same time regardless of the ages of the components. This creates a situation that the time to failure since the immediate previous inspection is random and has to be modelled by a distribution. This time is called the forward time and a limiting but closed form of such distribution is obtained. We develop an algorithm for the optimal solution of the decision process using a combination of analytical and enumeration approaches. The model is demonstrated by a numerical example. - Highlights: → Joint optimisation of maintenance and spare part inventory. → The use of the Delay-Time concept. → Block-based inspection. → Fixed order interval but variable order quantity.

In order to avoid both the high inventory level and the shortage of spare parts, an appointment policy of spare parts is first proposed based on the prediction of remaining useful lifetime, and then a corresponding joint optimization model of preventive maintenance and spare parts inventory is established. Due to the complexity of the model, the combination method of genetic algorithm and Monte Carlo is presented to get the optimal maximum inventory level, safety inventory level, potential failure threshold, and appointment threshold to minimize the cost rate. Finally, the proposed model is studied through a case study and compared with both the separate optimization and the joint optimization without appointment policy, and the results show that the proposed model is more effective. In addition, the sensitivity analysis shows that the proposed model is consistent with the actual situation of maintenance practices and inventory management.

    In asset intensive fields, where components are expensive and high system availability is required, spare parts procurement is often a critical issue. To gain competitiveness and market share is common for vendors to offer Total Business Volume Discounts (TBVD). Accordingly, companies must define the procurement and stocking policy of their spare parts in order to reduce procurement costs and increase asset availability. In response to those needs, this work presents an optimization model that maximizes the availability of the equipment under a TBVD environment, subject to a budget constraint. The model uses a single-echelon structure where parts can be repaired. It determines the optimal number of repairable spare parts to be stocked, giving emphasis on asset availability, procurement costs and service levels as the main decision criteria. A heuristic procedure that achieves high quality solutions in a fast and time-consistent way was implemented to improve the time required to obtain the model solution. Results show that using an optimal procurement policy of spare parts and accounting for TBVD produces better overall results and yields a better availability performance. - Highlights: • We propose a model for procurement of repairable components in single-echelon and business volume discount environments. • We used a mathematical model to develop a competitive heuristic that provides high quality solutions in very short times. • Our model places emphasis on using system availability, procurement costs and service levels as leading decision criteria. • The model can be used as an engine for a multi-criteria Decision Support System.

    This article presents a joint optimization of spare parts inventory and preventive maintenance. While minimizing CO_2 emissions, this approach is based on an optimal production plan achieved thanks to the HMMS model. The process which is studied in this paper only manufactures one type of product. The purpose of the paper is to determine for a random demand over a given period, a cost-effective production plan and a maintenance policy which integrates a spare parts strategy in accordance with environmental requirements and regulations. Our green spare parts management can be defined as a set of actions that are applied in order to decrease the spare parts footprint in its lifetime (Ba et al., 2015) [1]. Indeed, we take into account the spare parts characteristics (new or used) which will be used during maintenance actions (preventive or corrective) to preserve the environment. Consequently, we set up analytical models based on the effect of the production rate on the system deterioration so as to substantially cut the maintenance costs, production costs and CO_2 emissions. To evaluate the performance of our models, we give some illustrative examples. - Highlights: • Establishment of an optimal production plan for a manufacturing process. • Cost-effective maintenance strategy with a green spare parts strategy. • Possibility to choose between used and new spare parts to execute maintenance action.

    Ordering decision-making on spare parts is crucial in maximizing aircraft utilization and minimizing total operating cost. Extensive researches on spare parts inventory management and optimal allocation could be found based on the amount of historical operation data or condition-monitoring data. However, it is challengeable to make an ordering decision on spare parts under the case of establishment of a fleet by introducing new aircraft with little historical data. In this paper, spare parts supporting policy and ordering decision-making policy for new aircraft fleet are analyzed firstly. Then two-sample predictions for a Weibull distribution and a Weibull process are incorporated into forecast of the first failure time and failure number during certain time period using Bayesian and classical method respectively, according to which the ordering time and ordering quantity for spare parts are identified. Finally, a case study is presented to illustrate the methods of identifying the ordering time and ordering number of engine-driven pumps through forecasting the failure time and failure number, followed by a discussion on the impact of various fleet sizes on prediction results. This method has the potential to decide the ordering time and quantity of spare parts when a new aircraft fleet is established. - Highlights: • A modeling framework of ordering spare parts for a new fleet is proposed. • Models for ordering time and number are established based on two-sample prediction. • The computation of future failure time is simplified using Newtonian binomial law. • Comparison of the first failure time PDFs is used to identify process parameters. • Identification methods for spare parts are validated by Engine Driven Pump case study.

    Inventory management of spare parts is one of the most critical issues in the aeronautical industry, given the required level of system availability related to the strategic importance and high stocking costs of the components. Even if a large number of spare parts increases warehousing costs, every single shortage have a greater impact: the adoption of best-in-class inventory management techniques becomes crucial. On these considerations, the paper presents an innovative model of spare parts allocation for the Italian Air Force with the aim of minimizing backorders and, at the same time, ensuring an availability of 99% depending on the actual flight plan. The model, solved by a marginal analysis, considers an original configuration of features combining different skills of maintenance centers in a hierarchical multi-echelon, multi-item, multi-indenture structure. A real case is provided in order to analyze the solving method and the results. -- Highlights: •We studied a problem of allocations for spare parts of aeronautical systems. •The model presents different repair capabilities of maintenance centers. •The model fits constraints on budget and on total operational availability. •The model is solved by a marginal analysis with a backorder/price ratio. •A numerical example shows a spare parts allocation with relative considerations

    We develop and assess life cycle inventories of a conceptual offshore wind farm using a hybrid life cycle assessment (LCA) methodology. Special emphasis is placed on aspects of installation, operation, and maintenance, as these stages have been given only cursory consideration in previous LCAs. The results indicate that previous studies have underestimated the impacts caused by offshore operations and (though less important) exchange of parts. Offshore installation and maintenance activities cause 28% (10 g CO(2)-Eq/kWh) of total greenhouse gas emissions and 31-45% of total impact indicator values at the most (marine eutrophication, acidification, particulates, photochemical ozone). Transport and dumping of rock in installation phase and maintenance of wind turbines in use phase are major contributory activities. Manufacturing of spare parts is responsible for 6% (2 g CO2-Eq/kWh) of greenhouse gas emissions and up to 13% of total impact indicator values (freshwater ecotoxicity). Assumptions on lifetimes, work times for offshore activities and implementation of NOx abatement on vessels are shown to have a significant influence on results. Another source of uncertainty is assumed operating mode data for vessels determining fuel consumption rates.

    Diuretics enhance the renal excretion of Na(+) and water due to a direct action at different tubular sites of the nephron where solute re-absorption occurs. This paper focuses on the mechanism of action, pharmacodynamics, antihypertensive effects, adverse effects, interactions and contraindications of loop diuretics and potassium-sparing agents (including mineralocorticoid receptor antagonists (MRAs) and epithelial Na(+) channel blockers). Loop diuretics are less effective than thiazide diuretics in lowering blood pressure, so that their major use is in edematous patients with congestive heart failure (HF), cirrhosis with ascites and nephritic edema. MRAs represent a major advance in the treatment of resistant hypertension, primary and secondary hyperaldosteronism and in patients with systolic HF to reduce the risks of hospitalization and of premature death. Potassium-sparing diuretics when coadministered with diuretics (thiazides and loop diuretics) working at more proximal nephron locations reduce the risk of hypokalemia and hypomagnesemia and the risk of cardiac arrhythmias. At the end of the article, the basis for the combination of diuretics with other antihypertensive drugs to achieve blood pressure targets is presented.

    The strategy to recover components from discarded electrical and electronic equipment to obtain spare parts is promising, especially during the final service phase. In that phase, the original product is no longer produced and the sources of new parts are often limited. Controlling those closed-loop supply chains is challenging. Decision makers have to choose when to acquire discarded equipment, when to recover used parts, and when to produce new parts. We developed a generic system dynamics model that provides a test for various proposed policies to control closed-loop supply chains with parts recovery and spare-parts supply.

    1987-01-01

    As the nuclear industry shifts from a construction to an operations orientation, a number of fundamental changes have occurred in the type of safety-related procurements and the manner in which the utilities accomplish these procurements. Specifically, procurements have shifted from the purchase of large systems and components by architect-engineers, and nuclear steam supply system (NSSS) suppliers to the procurement by utilities of subassemblies, individual pieces of equipment (e.g., breakers, relays), and small parts for repairing individual pieces of equipment. To ensure that equipment will continue to perform its intended function and to satisfy regulatory requirements utilities must consider several things: (1) does the equipment perform a safety function; (2) does the replacement part affect the safety function; and (3) does the replacement part affect the seismic or environmental qualification. If the answer to any of these questions is yes, the purchaser has two alternatives. He may procure the item as safety-related and require the supplier or manufacturer to comply with all the applicable technical and quality requirements or he may purchase the item commercial grade and perform the necessary inspections and tests to ensure the item meets the requirements, i.e., dedicate the item

    Fernandez Carratala, L.

    1998-01-01

    There is an increasing difficulty for purchasing safety related spare items, with certifications by manufacturers for maintaining the original qualifications of the equipment of destination. The main reasons are, on the top of the logical evolution of technology, applied to the new manufactured components, the quitting of nuclear specific production lines and the evolution of manufacturers quality systems, originally based on nuclear codes and standards, to conventional industry standards. To face this problem, for many years different Dedication processes have been implemented to verify whether a commercial grade element is acceptable to be used in safety related applications. In the same way, due to our particular position regarding the spare part supplies, mainly from markets others than the american, C.N. Trillo has developed a methodology called Spare Items Validation. This methodology, which is originally based on dedication processes, is not a single process but a group of coordinated processes involving engineering, quality and management activities. These are to be performed on the spare item itself, its design control, its fabrication and its supply for allowing its use in destinations with specific requirements. The scope of application is not only focussed on safety related items, but also to complex design, high cost or plant reliability related components. The implementation in C.N. Trillo has been mainly curried out by merging, modifying and making the most of processes and activities which were already being performed in the company. (Author)

    Moncrief, E.C.; Schroder, R.M.

    1987-01-01

    A recent survey by the US Nuclear Regulatory Commission (NRC) of maintenance practices at US nuclear power plants confirms that spare parts availability is, to some extent, a problem at all but a few plants, and that 57% of the plants sometimes operated in a limiting condition for operation over the last year due to unavailability of spare parts. That's the bad news. The good news is that significant improvement is possible without ballooning inventory. The vast majority of total dollar value of spare parts inventory at power generation stations, whether nuclear or fossil, is rarely used (parts or components that are used 12 or less times per year including many with a history of no use for many years). Inventory Solutions of Akron, Ohio, has developed such a tool, called rarely used inventory stocking logic (RUSL) which is a user-friendly decision support tool for setting spare parts reorder points. Based on statistical computations enhanced to include the most advanced techniques developed for use in aerospace and military combat readiness, RUSL calculates the optimum stocking level to achieve the desired spare part availability at the station. In doing so, it considers the importance of the part in preventing an outage, as well as key economic ordering parameters, such as part cost, carrying cost, number of parts in service, historical observed usage, anticipated future usage, and lead time to replenish

    γ-Secretase is one of two proteases directly involved in the production of the amyloid β-peptide (Aβ), which is pathogenic in Alzheimer's disease. Inhibition of γ-secretase to suppress the production of Aβ should not block processing of one of its alternative substrates, Notch1 receptors, as interference with Notch1 signaling leads to severe toxic effects. In the course of our studies to identify γ-secretase inhibitors with selectivity for APP over Notch, 1 [3-(benzyl(isopropyl)amino)-1-(naphthalen-2-yl)propan-1-one] was found to inhibit γ-secretase-mediated Aβ production without interfering with γ-secretase-mediated Notch processing in purified enzyme assays. As 1 is chemically unstable, efforts to increase the stability of this compound led to the identification of 2 [naphthalene-2-carboxylic acid benzyl-isopropyl-amide] which showed similar biological activity to compound 1. Synthesis and evaluation of a series of amide analogs resulted in benzofuranyl amide analogs that showed promising Notch-sparing γ-secretase inhibitory effects. This class of compounds may serve as a novel lead series for further study in the development of γ-secretase inhibitors. Copyright © 2016 Elsevier Ltd. All rights reserved.

    A recent survey by the U.S. Nuclear Regulatory Commission of maintenance practices at U.S. nuclear power plants confirms that spare parts availability is, to some extent, a problem at all but a few plants. Fortunately, significant improvement is possible without ballooning inventory. The vast majority of total dollar value of spare parts inventory at power generation stations, whether nuclear or fossil, is rarely used (parts or components that are used 12 or less times per year including many with a history of no use for many years). Because rarely used inventory is not effectively managed with traditional inventory management techniques, opportunities exist both to increase availability and to reduce investment. But this requires a unique statistical tool that can recommend an unbiased, economic reorder point to be used in the materials management system. Inventory Solutions Inc. (ISI) of Akron, Ohio, has developed such a tool, rarely used inventory stocking logic (RUSL), which is a user friendly decision support tool for setting spare parts reorder points. RUSL, based on statistical computations enhanced to include the most advanced techniques developed for use in aerospace and military combat-readiness, calculates the optimum stocking level to achieve the desired spare part availability at the station

    AbstractWhen a product has been sold to a customer a new market arises for the company to earn profit from and to differentiate itself within. According to Bartwal, et al. (2010) the after sales market generally does not provide great revenues but good profits of the total revenue. In order to gain competiveness and live up to customer’s expectations a company needs to be efficient (Atkinson, 2004). He continuous that this can be accomplished if companies implement Lean. Lean is different too...

    The purpose of the Radiological Assistance Program (RAP) is to make DOE resources available and provide emergency assistance to state and local agencies in order to control radiological hazards, protect the public health and safety, and minimize the loss of property. This plan is an integral part of a nationwide program of radiological assistance established by the US DOE, and is implemented on a regional basis. The Brookhaven Area Office (BHO) Radiological Assistance Program is applicable to DOE Region I, which consists of the New England States, New York, New Jersey, Pennsylvania, Delaware, Maryland and the District of Columbia. The BHO RAP-1 has been developed to: (a) ensure the availability of an effective radiological assistance capability to ensure the protection of persons and property; (b) provide guidelines to RAP-1 Team personnel for the evaluation of radiological incidents and implementation of corrective actions; (c) maintain liaison with other DOE installations, Federal, State and local organizations which may become involved in radiological assistance operations in Region I; and (d) encourage development of a local capability to cope with radiological incidents

    2014-07-01

    The lifelong health of an individual is shaped during critical periods of development. The fetus is particularly susceptible to internal and external stimuli, many of which can alter developmental trajectories and subsequent susceptibility to disease. Glucocorticoids are critical in normal development of the fetus, as they are involved in the growth and maturation of many organ systems. The surge in fetal glucocorticoid levels that occurs in most mammalian species over the last few days of pregnancy is an important developmental switch leading to fundamental changes in gene regulation in many organs, including the brain. These changes are important for the transition to postnatal life. Exposure of the fetus to increased levels of glucocorticoids, resulting from maternal stress or treatment with synthetic glucocorticoids, can lead to long-term 'programming' of hypothalamic-pituitary-adrenal function and behaviours. Glucocorticoids act at multiple levels within the fetal brain. Growing evidence indicates that they can exert powerful effects on the epigenome, including on DNA methylation, histone acetylation and microRNA, to influence gene expression. Such influences probably represent a critical component of the 'programming' process, and might be partly responsible for the transgenerational effects of antenatal glucocorticoid exposure on neurologic, cardiovascular and metabolic function.

    2014-07-01

    Fetal development is a critical period for shaping the lifelong health of an individual. However, the fetus is susceptible to internal and external stimuli that can lead to adverse long-term health consequences. Glucocorticoids are an important developmental switch, driving changes in gene regulation that are necessary for normal growth and maturation. The fetal hypothalamic-pituitary-adrenal (HPA) axis is particularly susceptible to long-term programming by glucocorticoids; these effects can persist throughout the life of an organism. Dysfunction of the HPA axis as a result of fetal programming has been associated with impaired brain growth, altered behaviour and increased susceptibility to chronic disease (such as metabolic and cardiovascular disease). Moreover, the effects of glucocorticoid-mediated programming are evident in subsequent generations, and transmission of these changes can occur through both maternal and paternal lineages.

  10. Andrew spares Florida Coast

    Science.gov (United States)

    Bush, Susan

    When geologists heard of the intensity of Hurricane Andrew, which struck the Florida coast on August 25 and then moved on to southern Louisiana, they were expecting the same kinds of coastal damage that Hurricane Hugo brought to the Caribbean and Carolina shores in 1989. Both storms were category 4 hurricanes, having winds of 131-155 mph and surges of 13-18 feet. However, the coastal damage never materialized, leaving geologists to analyze the factors that lessened the impact of the storm. “For minimum coastal damage, you couldn't have designed a better storm,” said Orrin Pilkey, director of the Program for the Study of Developed Shorelines (PSDS) in Durham, N.C. This was due in part to the nature of the storm itself and where it hit land, and in part to the regional geology, said Rob Thieler of PSDS. Despite the huge amounts of damage to buildings, there was virtually no evidence of coastal process destruction, he said.

    Experimental Program: assembly of an experiment as Fermilab E-531 to measure decay lifetimes, with tagged emulsion of charmed particles produced by high energy neutrinos was finished, and data taking now is in progress. An experiment to measure prompt neutrino production at Fermilab, E-613, was approved and detailed design of it is continuing. Search for parity violation in scattering of polarized protons, an experiment E-446-ZGS at ANL, was performed with the sensitivity of 10 -6 for detection of that process and yielded null results. Another run with improved sensitivity of 10 -7 is in preparation. Data analysis of the neutrino experiment E-310 at Fermilab will continue. Trimuon events, a new discovery, were identified in those data. Analysis of data on meson production from experiments performed at the ZGS--ANL, E-397, E-420 and E-428, with charged and neutral spectrometer will continue. A new relatively broad resonance (T approx. 70 MeV) with quantum numbers IJ/sup P/ = 00 -1 was discovered in the data from E-397. Analysis of beta decay of polarized Σ - hyperons is in progress. Participation in the design of the experimental areas for the Isabelle colliding proton beam accelerator will continue. Theoretical Program: topics of current interest in particle theory which will be investigated in the coming year are: the instanton-anti-instanton QCD gauge fields, discrete symmetries which may determine quark masses in the SU(2) x U(1) model, calculation of charmed meson production in e + e - collisions and formation of gluon jets, Higgs boson production in pp collisions, calculation of Higgs boson mass in terms of vector boson mass, study of Lagrangians with gauge and Higgs scalar fields, investigation of Faddeev--Popov determinants as related to quantum chromodynamics, a study of quantum flavor dynamics and anomalies in the axial vector Ward identity and a study of super symmetry as a part of a realistic model of leptonic interactions

  14. The "spare parts person"? Conceptions of the human body and their implications for public attitudes towards organ donation and organ sale

    Science.gov (United States)

    Schweda, Mark; Schicktanz, Silke

    2009-01-01

    Background The increasing debate on financial incentives for organ donation raises concerns about a "commodification of the human body". Philosophical-ethical stances on this development depend on assumptions concerning the body and how people think about it. In our qualitative empirical study we analyze public attitudes towards organ donation in their specific relation to conceptions of the human body in four European countries (Cyprus, Germany, the Netherlands and Sweden). This approach aims at a more context-sensitive picture of what "commodification of the body" can mean in concrete clinical decisions concerning organ donation. Results We find that moral intuitions concerning organ donation are rooted in various conceptions of the human body and its relation to the self: a) the body as a mechanical object owned by the self, b) the body as a part of a higher order embodying the self, and c) the body as a hierarchy of organs constitutive of the self. Conclusion The language of commodification is much too simple to capture what is at stake in everyday life intuitions about organ donation and organ sale. We discuss how the plurality of underlying body-self conceptions can be taken into account in the ethical debate, pointing out consequences for an anthropologically informed approach and for a liberal perspective.

    1980-03-01

    TRAB is a transient analysis program for BWR. The present report describes its principles. The program has been developed from TRAWA-program. It models the interior of the pressure vessel and related subsystems of BWR viz. reactor core, recirculation loop including the upper part of the vessel, recirculation pumps, incoming and outgoing flow systems, and control and protection systems. Concerning core phenomena and all flow channel hydraulics the submodels are one-dimensional of main features. The geometry is very flexible. The program has been made particularly to simulate various reactivity transients, but it is applicable more generally to reactor incidents and accidents in which no flow reversal or no emptying of the circuit must occur below the water level. The program is extensively supplied by input and output capabilities. The user can act upon the simulation of a transient by defining external disturbances, scheduled timevariations for any system variable, by modeling new subsystems, which are representable with ordinary linear differential equations, and by defining relations of functional form between system variables. The run of the program can be saved and restarted. (author)

    The compact sodium cooled nuclear reactor KNK I of the Karlsruhe Research Center reached full power for the first time in February 1974. The goal of KNK I is to collect experience for the construction and operation of larger reactors, such as SNR 300. In order to deepen these experiences, a test program was drawn up and conducted from 1973 until 1975 within the framework of R and D work on the development of fast breeder reactors. The program included individual tasks concerning reactor design, safety instrumentation, irradiation and post-examination as well as behavior of components during operation. The performance of the tests was essentially governed by the licensing procedure imposed under the atomic energy act for the construction and operation of nuclear facilities.

In this case we will discuss some aspects of the test application Jacobson S. (2011. Purpose of study and hypothesis: In neurolinguistic programming (NLP we have studied the relationship between sensory submodalities, in accordance with the Jacobson test (2011. We wanted to check the degree of significance of the mean difference parameters studied and if the materiality result falls within the objective parameters. If ideomotor representations of athletes are completed with multiple sensations of all sensory submodalities such as visual, auditory, kinesthetic, olfactory and gustatory, the possibility of applying the techniques of NLP (neurolinguistic programming will have more effective results. Methods and material: two records were made by using two tests, test1 and test2 on master students of the University “Babes-Bolyai” Cluj-Napoca, from FEFS from APS department (training and sports performance.

    2014-01-01

    Full Text Available Culture is a form of creative expression of a human being through which he reshapes the world, acts on it adding it value and creating new, cultural values. A human being is able to create a product of culture only when he is free and able to express himself. A contemporary man can incorporate various cultural activities into his spare time. They are especially important when they concern children and young people: regardless of whether they are used in institutional settings or in spare time. The authors conducted an empirical research of students' assumptions and beliefs concerning cultural activities in their free time. The sample comprised 233 fifth grade students. The findings show that in their spare time fifth graders: engage in various cultural activities; that students who live in urban areas attend more cultural events; that students have the opportunity to engage in extra-curricular activities in the area of culture - join cultural and artistic groups and associations and engage in various creative pursuits at different levels of participation (as consumers, full participants; and that students' attitudes concerning the influence of parents and teachers on the selection of cultural activities to be pursued do not vary greatly by gender, location or school achievement. Cultural activities do play a significant part in the free time of primary school students. This is why it is important that guidance provided in school and in spare time should be brought in greaer harmony.

  20. Sparing land for biodiversity at multiple spatial scales

    Directory of Open Access Journals (Sweden)

    Johan eEkroos

    2016-01-01

    Full Text Available A common approach to the conservation of farmland biodiversity and the promotion of multifunctional landscapes, particularly in landscapes containing only small remnants of non-crop habitats, has been to maintain landscape heterogeneity and reduce land-use intensity. In contrast, it has recently been shown that devoting specific areas of non-crop habitats to conservation, segregated from high-yielding farmland (‘land sparing’, can more effectively conserve biodiversity than promoting low-yielding, less intensively managed farmland occupying larger areas (‘land sharing’. In the present paper we suggest that the debate over the relative merits of land sparing or land sharing is partly blurred by the differing spatial scales at which it is suggested that land sparing should be applied. We argue that there is no single correct spatial scale for segregating biodiversity protection and commodity production in multifunctional landscapes. Instead we propose an alternative conceptual construct, which we call ‘multiple-scale land sparing’, targeting biodiversity and ecosystem services in transformed landscapes. We discuss how multiple-scale land sparing may overcome the apparent dichotomy between land sharing and land sparing and help to find acceptable compromises that conserve biodiversity and landscape multifunctionality.

    Lips, Irene M.; Vonk, Ernest J.A.; Koster, Mariska E.Y.; Houwing, Ronald H.

    2011-01-01

    Erlotinib is an epidermal growth factor receptor inhibitor prescribed to patients with locally advanced or metastasized non-small cell lung carcinoma after failure of at least one earlier chemotherapy treatment. Approximately 75% of the patients treated with erlotinib develop acneiform skin rashes. A patient treated with erlotinib 3 months after finishing concomitant treatment with chemotherapy and radiotherapy for non-small cell lung cancer is presented. Unexpectedly, the part of the skin that had been included in his previously radiotherapy field was completely spared from the erlotinib-induced acneiform skin rash. The exact mechanism of erlotinib-induced rash sparing in previously irradiated skin is unclear. The underlying mechanism of this phenomenon needs to be explored further, because the number of patients being treated with a combination of both therapeutic modalities is increasing. The therapeutic effect of erlotinib in the area of the previously irradiated lesion should be assessed. (orig.)

    The vacuum system of Synchrotron Radiation Source, Indus-2, in RRCAT has been functioning up to the mark, continuously for last 10 years. To continue the same trouble-free functioning, it was planned to procure spares for all critical vacuum components, test for UHV performance and keep ready for installation, in case of requirement. As a part of this planning, fifteen chambers made of Aluminium alloy (6063 T6), procured as spare straight section chambers for Indus-2, and were tested for UHV performance. They were tested in batches of 2 or 3 chambers, depending upon their length, and the similar testing-procedure was followed. This paper narrates the tests carried out, and the results obtained. Ultimate vacuum in the range (2 to 9) x 10 -10 mbar was achieved. (author)

    The XRS instrument on Astro-E is a fully self-contained microcalorimeter x-ray instrument capable of acquiring optimally filtering, and characterizing events for 32 independent pixels. With the launch of the Astro-E spacecraft, a full flight spare detector system has been integrated into a laboratory cryostat for use on the electron beam ion trap (EBIT) at Lawrence Livermore National Laboratory. The detector system contains a microcalorimeter array with 32 instrumented pixels heat sunk to 60 mK using an adiabatic demagnetization refrio,erator. The instrument has a composite resolution of 8eV at 1 keV and 12eV at 6 keV with a minimum of 95% quantum efficiency. This will allow high spectral resolution, broadband observations of collisionally excited plasmas which are produced in the EBIT experiment. Unique to our instrument are exceptionally well characterized 1000 Angstrom thick aluminum on polyimide infrared blocking filters. The detailed transmission function including the edc,e fine structure of these filters has been measured in our laboratory using an erect field grating spectrometer. This will allow the instrument to perform the first broadband absolute flux measurements with the EBIT instrument. The instrument performance as well as the results of preliminary measurements will be discussed.

    2014-01-01

    The recently issued International Atomic Energy Agency (IAEA) publications (GS-R-3, GS-G-3.1 and GS-G-3.5) regarding Management Systems for Facilities and Activities define requirements for creation, introduction, evaluation and continuously improvement of the Management System, which unifies the safety, health, environment, security, quality and economic elements. According to GS-R-3 the Integrated Management System is based on defined processes identified in the enterprises: Managing, Basic and Supporting processes. At implementation of their activities, the organizations often apply other standards in their interrelations with suppliers and the parties concerned - ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007, regarding quality, environment and occupational health and safety management. The integration of the standards of both series ensure the observance of the common management principles that reflect the best practices of management as leadership, participation of the people, process approach, continuously improvement, systematical approach to the management and approach based on facts used at the making decisions. The main objective of the Integrated Management System introduction is to ensure safety considering the influence of all additional impacts taken together. The Integrated Management System is based on the process approach at implementation of the activities in nuclear power plant. The transition to the process oriented approach require long period of time, during which the distribution of the responsibilities is optimized up to the level that will satisfy the requirements, reach and maintain the stipulated objectives. The Configuration Management (CM) is an integrated management process by means of which conformity between design requirements, physical configuration and the plant documentation is ascertained and maintained during the entire life cycle of the facility. Processes within configuration management are not isolated, but are part of

  19. Perseus A, Part of the ERAST Program, in Flight

    Science.gov (United States)

    1993-01-01

    was the third generation of the Perseus design, which began with the Perseus Proof-Of-Concept aircraft. Perseus was initially developed as part of NASA's Small High-Altitude Science Aircraft (SHASA) program, which later evolved into the ERAST project. The Perseus Proof-Of-Concept aircraft first flew in November 1991 and made three low-altitude flights within a month to validate the Perseus aerodynamic model and flight control systems. Next came the redesigned Perseus A, which incorporated a closed-cycle combustion system that mixed oxygen carried aboard the aircraft with engine exhaust to compensate for the thin air at high altitudes. The Perseus A was towed into the air by a ground vehicle and its engine started after it became airborne. Prior to landing, the engine was stopped, the propeller locked in horizontal position, and the Perseus A glided to a landing on its unique bicycle-type landing gear. Two Perseus A aircraft were built and made 21 flights in 1993-1994. One of the Perseus A aircraft reached over 50,000 feet in altitude on its third test flight. Although one of the Perseus A aircraft was destroyed in a crash after a vertical gyroscope failed in flight, the other aircraft completed its test program and remains on display at Aurora's facility in Manassas. Perseus B first flew Oct. 7, 1994, and made two flights in 1996 before being damaged in a hard landing on the dry lakebed after a propeller shaft failure. After a number of improvements and upgrades-including extending the original 58.5-foot wingspan to 71.5 feet to enhance high-altitude performance--the Perseus B returned to Dryden in the spring of 1998 for a series of four flights. Thereafter, a series of modifications were made including external fuel pods on the wing that more than doubled the fuel capacity to 100 gallons. Engine power was increased by more than 20 percent by boosting the turbocharger output. Fuel consumption was reduced with fuel control modifications and a leaner fuel-air mixture

  4. Programming a real code in a functional language (part 1)

    Energy Technology Data Exchange (ETDEWEB)

    Hendrickson, C.P.

    1991-09-10

    For some, functional languages hold the promise of allowing ease of programming massively parallel computers that imperative languages such as Fortran and C do not offer. At LLNL, we have initiated a project to write the physics of a major production code in Sisal, a functional language developed at LLNL in collaboration with researchers throughout the world. We are investigating the expressibility of Sisal, as well as its performance on a shared-memory multiprocessor, the Y-MP. An interesting aspect of the project is that Sisal modules can call Fortran modules, and are callable by them. This eliminates the rewriting of 80% of the production code that would not benefit from parallel execution. Preliminary results indicate that the restrictive nature of the language does not cause problems in expressing the algorithms we have chosen. Some interesting aspects of programming in a mixed functional-imperative environment have surfaced, but can be managed. 8 refs.

    2016-01-01

    Full Text Available Objectives: The protein-sparing modified fast (PSMF is a rigorous way of rapidly losing a large amount of weight. Although adult studies have shown the PSMF to be effective, data in adolescents are lacking. The aim of this study was to determine the efficacy and safety of the PSMF in severely obese adolescents. Methods: 12 subjects who were evaluated in the Obesity Management Program at the Cleveland Clinic from 2011 to 2014 were included. The subjects were initiated on the PSMF after failing other conventional methods of weight loss. Once the goal weight was achieved, subjects were transitioned to the refeeding phase for weight maintenance. Results: Follow-up was scheduled at 3-month (11 patients and 6-month (6 patients intervals. At the 6-month follow-up visit, the average weight loss was 11.19 kg (95% confidence interval = -5.4, -27.8, P = .028, with average of 9.8% from baseline. Fifty percent of subjects had >5% weight loss and 20% had >10% weight loss. Four patients were lost to the follow-up (40%. An improvement was noted in total cholesterol and high-density lipoprotein. Due to a small sample size these results were not statistically significant. Side effects reported by subjects were mild dehydration due to nausea (2 patients, decreased energy (1 patient, and transient labile mood (1 patient. No life-threatening side effects were reported. Conclusion: Our results show that the PSMF diet can be used as an effective and safe method in the outpatient setting for rapid weight loss in adolescents with severe obesity.

    Whitman, G.D.

    1975-01-01

    The testing of the intermediate pressure vessels is a major activity under the Heavy Section Steel Technology Program. A primary objective of these tests is to develop or verify methods of fracture prediction, through the testing of selected structures and materials, in order that a valid basis can be established for evaluating the serviceability and safety of light-water reactor pressure vessels. These vessel tests were planned with sufficiently specific objectives that substantial quantitative weight could be given to the results. Each set of testing conditions was chosen so as to provide specific data by which analytical methods of predicting flaw growth, and in some cases crack arrest, could be evaluated. Every practical effort was made to assure that results would be relevant to some aspect of real reactor pressure vessel performance through careful control of material properties, selection of test temperatures, and design of prepared flaws. 5 references

    1993-01-01

    This work is carried out under cost-sharing contract with European Atomic Energy Community in the framework of its programme on Management and Storage of Radioactive Wastes. Part 1: PMATCH, A Program to Manage Thermochemical Data, describes the development and use of a computer program, by means of which new thermodynamic data from literature may be referenced to a common frame and thereby become internally consistent with an existing database. The report presents the relevant thermodynamic expressions and their use in the program is discussed. When there is not sufficient thermodynamic data available to describe a species behaviour under all conceivable conditions, the problems arising are thoroughly discussed and the available data is handled by approximating expressions. Part II: The Experimental Validation of Geochemical Computer models are the results of experimental investigations of the equilibria established in aqueous suspensions of mixtures of carbonate minerals (Calcium, magnesium, manganese and europium carbonates) compared with theoretical calculations made by means of the geochemical JENSEN program. The study revealed that the geochemical computer program worked well, and that its database was of sufficient validity. However, it was observed that experimental difficulties could hardly be avoided, when as here a gaseous component took part in the equilibria. Whereas the magnesium and calcium carbonates did not demonstrate mutual solid solubility, this produced abnormal effects when manganese and calcium carbonates were mixed resulting in a diminished solubility of both manganese and calcium. With tracer amounts of europium added to a suspension of calcite in sodium carbonate solutions long term experiments revealed a transition after 1-2 months, whereby the tracer became more strongly adsorbed onto calcite. The transition is interpreted as the nucleation and formation of a surface phase incorporating the 'species' NaEu(Co 3 ) 2

    In recent years, it has become commonplace for universities to hire part-time and non-tenure track faculty to save money. This study examined how commonly part-time faculty are used in health education and how they are used to meet program needs. The American Association of Health Education's 2009 "Directory of Institutions Offering Undergraduate and Graduate Degree Programs in Health Education" was used to send a three-wave mailing to programs that were not schools of public health (n = 215). Of the 125 departments (58%) that responded, those that used part-time faculty averaged 7.5 part-time faculty in the previous academic year, teaching on average a total of 10 classes per year. A plurality of departments (38%) were currently using more part-time faculty than 10 years ago and 33% perceived that the number of part-time faculty has resulted in decreases in the number of full-time positions. Although 77% of department chairs claimed they would prefer to replace all of their part-time faculty with one full-time tenure track faculty member. As colleges downsize, many health education programs are using more part-time faculty. Those faculty members who take part-time positions will likely be less involved in academic activities than their full-time peers. Thus, further research is needed on the effects of these changes on the quality of health education training and department productivity.

    This three-part study examines how four-year universities in the United States with baccalaureate programs in aviation management include ethics instruction in their curricula. Based on a literature review, no research exists to describe the current status of teaching ethics to aviation students. Yet concurrently, unethical activities reported in the media involving the aviation industry indicates the need for such programs. Part One of this study justifies the need for ethics education and develops a series of hypotheses to evaluate the current status of ethics instruction, which was investigated and will be reported on in Parts Two and Three of this study, respectively.

    2015-10-01

    Full Text Available A training program for animal and human health professionals has been implemented in Azerbaijan through a joint agreement between the United States Defense Threat Reduction Agency and the Government of Azerbaijan. The training program is administered as part of the Cooperative Biological Engagement Program, and targets key employees in Azerbaijan’s disease surveillance system including physicians, veterinarians, epidemiologists, and laboratory personnel. Training is aimed at improving detection, diagnosis, and response to especially dangerous pathogens, although the techniques and methodologies can be applied to other pathogens and diseases of concern. Biosafety and biosecurity training is provided to all trainees within the program. Prior to 2014, a variety of international agencies and organizations provided training, which resulted in gaps related to lack of coordination of training materials and content. In 2014 a new training program was implemented in order to address those gaps. This paper provides an overview of the Cooperative Biological Engagement Program training program in Azerbaijan, a description of how the program fits into existing national training infrastructure, and an evaluation of the new program’s effectiveness to date. Long-term sustainability of the program is also discussed.

    The elastic-plastic FEM code described in this report is the third part of the Lamcal program of which the two other parts for mesh generating and plotting were presented previously. Also this part uses the dynamic core storage. All variables and problem defining data are stored in one common array-SPACE. If all three parts are used together, the same common-SPACE is reused in each part. The lay-out of the complete program is given. J-integral evaluation and plotting can be done immediately in the FE run or afterwards in a post processing run. Post processing is done within the FEM part with a reduced core space. Originally developed as a general code, the use of the present version is mainly focussed on research in the field of the fracture mechanics. Several J-integral routines are available as well as crack growth modelling by node release or stiffness reduction, energy calculations, crack tip elements, etc. In this report the theory is discussed and some sample problems are given. The theory is presented in two parts, the general FEM and the more specific EPFM theory. For the sample problems, a choice has been made to show the accuracy of the program under more or less severe loading conditions

    To evaluate our results of valve-sparing aortic root replacement and associated (multiple) valve repair. From September 2003 to September 2013, 97 patients had valve-sparing aortic root replacement procedures. Patient records and preoperative, postoperative and recent echocardiograms were reviewed. Median age was 40.3 (range: 13.4-68.6) years and 67 (69.1%) were male. Seven (7.2%) patients were younger than 18 years, the youngest being 13.4 years. Fifty-four (55.7%) had Marfan syndrome, 2 (2.1%) other fibrous tissue diseases, 15 (15.5%) bicuspid aortic valve and 3 (3.1%) had earlier Fallot repair. The reimplantation technique was used in all, with a straight vascular prosthesis in 11 (26-34 mm) and the Valsalva prosthesis in 86 (26-32 mm). Concomitant aortic valve repair was performed in 43 (44.3%), mitral valve repair in 10 (10.3%), tricuspid valve repair in 5 (5.2%) and aortic arch replacement in 3 (3.1%). Mean follow-up was 4.2 ± 2.4 years. Follow-up was complete in all. One 14-year old patient died 1.3 years post-surgery presumably of ventricular arrhythmia. One patient underwent reoperation for aneurysm of the proximal right coronary artery after 4.9 years and 4 patients required aortic valve replacement, 3 of which because of endocarditis after 0.1, 0.8 and 1.3 years and 1 because of cusp prolapse after 3.8 years. No thrombo-embolic complications occurred. Mortality, root reoperation and aortic regurgitation were absent in 88.0 ± 0.5% at 5-year follow-up. Results of valve-sparing root replacement are good, even in association with a high incidence of concomitant valve repair. Valve-sparing aortic root replacement can be performed at a very young age as long as an adult size prosthesis can be implanted. © The Author 2014.

    2011-10-01

    This study consisted of two parts. Part 1 was a survey of US program directors, and Part 2 reports on the survey findings distributed to the deans of US dental schools. Both surveys evaluated observations of trends in prosthodontic education. The first survey (2005) of program directors and deans was published in 2007. This second survey was conducted in 2009. The 2009 survey provided 10-year data on trends in prosthodontics as reported by program directors. A national e-mail survey of 46 program directors was used to collect enrollment data for years 1 to 3 of prosthodontics training for US and international dental school graduates, the total number of applicants and applications considered, and the trends over time of applicants to prosthodontics for US dental school graduates and for international graduates. In addition, the program directors were asked to rank 13 key factors that may have contributed to any changes in the prosthodontic applicant pool. Program directors were also asked for information on student financial incentives and whether their programs were state or federally funded, and whether their sponsoring institution was a dental school. Of the 46 program directors, 40 responded, for an 87% response rate. Respondents reported that 66% of their enrollees were graduates of US dental schools. Between 2000 and 2009 the applicant pool in prosthodontics nearly doubled, with 50% of the program directors reporting an increase in US-trained applicants, 42.5% reporting no change, and only 7.5% reporting a decrease. Using the Spearman correlation for the 10-year survey, there was a positive, statistically significant correlation that society's demand for a higher level of training and credentialing and interest in prosthodontics among dental students contributed to an increase in the number of US dental graduates applying to prosthodontic programs. Only four programs offered no financial packages to offset tuition. The remaining 36 respondents reported some

  11. Incorporating single-side sparing in models for predicting parotid dose sparing in head and neck IMRT

    International Nuclear Information System (INIS)

    Yuan, Lulin; Wu, Q. Jackie; Yin, Fang-Fang; Yoo, David; Jiang, Yuliang; Ge, Yaorong

    2014-01-01

    Purpose: Sparing of single-side parotid gland is a common practice in head-and-neck (HN) intensity modulated radiation therapy (IMRT) planning. It is a special case of dose sparing tradeoff between different organs-at-risk. The authors describe an improved mathematical model for predicting achievable dose sparing in parotid glands in HN IMRT planning that incorporates single-side sparing considerations based on patient anatomy and learning from prior plan data. Methods: Among 68 HN cases analyzed retrospectively, 35 cases had physician prescribed single-side parotid sparing preferences. The single-side sparing model was trained with cases which had single-side sparing preferences, while the standard model was trained with the remainder of cases. A receiver operating characteristics (ROC) analysis was performed to determine the best criterion that separates the two case groups using the physician's single-side sparing prescription as ground truth. The final predictive model (combined model) takes into account the single-side sparing by switching between the standard and single-side sparing models according to the single-side sparing criterion. The models were tested with 20 additional cases. The significance of the improvement of prediction accuracy by the combined model over the standard model was evaluated using the Wilcoxon rank-sum test. Results: Using the ROC analysis, the best single-side sparing criterion is (1) the predicted median dose of one parotid is higher than 24 Gy; and (2) that of the other is higher than 7 Gy. This criterion gives a true positive rate of 0.82 and a false positive rate of 0.19, respectively. For the bilateral sparing cases, the combined and the standard models performed equally well, with the median of the prediction errors for parotid median dose being 0.34 Gy by both models (p = 0.81). For the single-side sparing cases, the standard model overestimates the median dose by 7.8 Gy on average, while the predictions by the combined

  12. Optimized lens-sparing treatment of retinoblastoma with electron beams

    International Nuclear Information System (INIS)

    Steenbakkers, Roel J.H.M.; Altschuler, Martin D.; D'Angio, Giulio J.; Goldwein, Joel W.; Kassaee, Alireza

    1997-01-01

    Purpose: The ideal lens-sparing radiotherapy technique for retinoblastoma calls for 100% dose to the entire retina including the ora serrata and zero dose to the lens. Published techniques, most of which use photons, have not accomplished this ideal treatment. We describe here a technique that approaches this ideal configuration using electron beam therapy. Methods and Materials: Dose-modeling calculations were made using a computer program built around a proprietary algorithm. This program calculates 3D dose distribution for electrons and photons and uses the Cimmino feasibility method for the inverse problem of beam weighting to achieve the prescribed dose. The algorithm has been verified in the ocular region by measurements in a RANDO phantom. To search for an ideal lens-sparing beam setup, a stylized phantom of an 8-month-old infant was generated with built-in inhomogeneities, and a phantom of a 5-year-old child was generated from a patient CT series. Results: Of more than 100 different beam setups tested, two 9 MeV electron beams at gantry angles plus and minus 26 degrees from the optic nerve axis achieved the best distribution. Both fields have a lens block and an isocenter between the globe and origin of the optic nerve. When equal doses are given to both fields, the entire extent of the retina (including ora serrata) received 100%, while the lens received 10% or less. Conclusion: The two-oblique-electron-beam technique here described appears to meet most of the stringent dosimetry needed to treat retinoblastoma. It is suitable for a range of ages, from infancy to early childhood years

  20. Conserving the birds of Uganda's banana-coffee arc: land sparing and land sharing compared.

    Directory of Open Access Journals (Sweden)

    Mark F Hulme

    Full Text Available Reconciling the aims of feeding an ever more demanding human population and conserving biodiversity is a difficult challenge. Here, we explore potential solutions by assessing whether land sparing (farming for high yield, potentially enabling the protection of non-farmland habitat, land sharing (lower yielding farming with more biodiversity within farmland or a mixed strategy would result in better bird conservation outcomes for a specified level of agricultural production. We surveyed forest and farmland study areas in southern Uganda, measuring the population density of 256 bird species and agricultural yield: food energy and gross income. Parametric non-linear functions relating density to yield were fitted. Species were identified as "winners" (total population size always at least as great with agriculture present as without it or "losers" (total population sometimes or always reduced with agriculture present for a range of targets for total agricultural production. For each target we determined whether each species would be predicted to have a higher total population with land sparing, land sharing or with any intermediate level of sparing at an intermediate yield. We found that most species were expected to have their highest total populations with land sparing, particularly loser species and species with small global range sizes. Hence, more species would benefit from high-yield farming if used as part of a strategy to reduce forest loss than from low-yield farming and land sharing, as has been found in Ghana and India in a previous study. We caution against advocacy for high-yield farming alone as a means to deliver land sparing if it is done without strong protection for natural habitats, other ecosystem services and social welfare. Instead, we suggest that conservationists explore how conservation and agricultural policies can be better integrated to deliver land sparing by, for example, combining land-use planning and agronomic

    Radiology has gained importance in the non-invasive diagnosis of hepatic steatosis. Ultrasonography is usually the first imaging modality for the evaluation of hepatic steatosis. Unenhanced CT with or without dual kVp measurement and MRI with in and out of phase sequence can allow objective evaluation of hepatic steatosis. However, none of the imaging modalities can differentiate non-alcoholic steatohepatitis/fatty liver disease from simple steatosis. Evaluation of hepatic steatosis is important in donor evaluation before orthotopic liver transplantation and hepatic surgery. Recently, one-stop shop evaluation of potential liver donors has become possible by CT and MRI integrating vascular, parenchymal, volume and steatosis evaluation. Moreover hepatic steatosis (diffuse, multinodular, focal, subcortical, perilesional, intralesional, periportal and perivenular), hypersteatosis and sparing (geographic, nodular and perilesional or peritumoral) can cause diagnostic problems as a pseudotumor particularly in the evaluation of oncology patients. Liver MRI is used as a problem-solving tool in these patients. In this review, we discuss the current role of radiology in diagnosing, quantifying hepatic steatosis and solutions for diagnostic problems associated with fatty infiltration and sparing.

  4. A decision-making framework to integrate maintenance contract conditions with critical spares management

    International Nuclear Information System (INIS)

    Godoy, David R.; Pascual, Rodrigo; Knights, Peter

    2014-01-01

    Maintenance outsourcing is a strategic driver for asset intensive industries pursuing to enhance supply chain performance. Spare parts management plays a relevant role in this premise since its significant impact on equipment availability, and hence on business success. Designing critical spares policies might therefore seriously affect maintenance contracts profitability, yet service receivers and external providers traditionally attempt to benefit separately. To coordinate both chain parties, we investigated whether the spare components pool should be managed in-house or contracted out. This paper provides a decision-making framework to efficiently integrate contractual conditions with critical spares stockholding. Using an imperfect maintenance strategy over a finite horizon, the scheme maximizes chain returns whilst evaluating the impact of an additional part to stock. As result, an original joint value – preventive interval and stock level – sets the optimal agreement to profitably allocate the components pool within the service contract. Subsidization bonuses on preventive interventions and pooling costs are also estimated to induce the service provider to adjust its policy when needed. The proposed contractual conditions motivate stakeholders to continuously improve maintenance performance and supply practices, thus obtaining higher joint benefits

    Gordon, Sanford; Mcbride, Bonnie J.

    1994-01-01

    This report presents the latest in a number of versions of chemical equilibrium and applications programs developed at the NASA Lewis Research Center over more than 40 years. These programs have changed over the years to include additional features and improved calculation techniques and to take advantage of constantly improving computer capabilities. The minimization-of-free-energy approach to chemical equilibrium calculations has been used in all versions of the program since 1967. The two principal purposes of this report are presented in two parts. The first purpose, which is accomplished here in part 1, is to present in detail a number of topics of general interest in complex equilibrium calculations. These topics include mathematical analyses and techniques for obtaining chemical equilibrium; formulas for obtaining thermodynamic and transport mixture properties and thermodynamic derivatives; criteria for inclusion of condensed phases; calculations at a triple point; inclusion of ionized species; and various applications, such as constant-pressure or constant-volume combustion, rocket performance based on either a finite- or infinite-chamber-area model, shock wave calculations, and Chapman-Jouguet detonations. The second purpose of this report, to facilitate the use of the computer code, is accomplished in part 2, entitled 'Users Manual and Program Description'. Various aspects of the computer code are discussed, and a number of examples are given to illustrate its versatility.

    2008-05-01

    Based on our recently published anatomic studies, we present the most recent refinement of the endoscopic extraperitoneal radical prostatectomy (EERPE), the intrafascial nerve-sparing EERPE (nsEERPE). As part of the intrafascial technique, the dissection plane is directly on the prostatic capsule, freeing the prostate laterally from its thin surrounding fascia that contains small vessels and nerves. The technique enables puboprostatic ligament preservation, leaving intact endopelvic fascia, periprostatic fascia, and neurovascular bundles. The operation was performed in 150 patients with indications for nerve-sparing procedure. The mean operative time was 131 min (range: 50-210 min) and the mean catheterization time was 5.9 d (range: 4-20 d). Twelve months postoperatively, 94.3% of the patients were continent (no need for pads), 4.6% had minimal stress incontinence, and one patient required >2 pads/d. At the 12-mo follow-up, the potency rates (erections sufficient for intercourse with or without the use of phosphodiesterase 5 [PDE5] inhibitors) of the patients who underwent bilateral intrafascial nsEERPE were 89.7% (age: 44-55 yr), 81.1% (age: 56-65 yr), and 61.9% (age: >65 yr). Positive surgical margins in pT2 and pT3 tumors were 4.5% and 29.4%, respectively. The intrafascial nsEERPE enables the dissection of the prostate with limited trauma to the surrounding fascias and the enclosed neurovascular bundles. We propose that the preserved neurovascular bundles with intrafascial nsEERPE are more viable. The results advocate this proposition.

    At Indiana University School of Dentistry, a New Clinical Faculty Training (NCFT) program was created with the primary goals of informing new part-time faculty members of clinical policies and assessment guidelines and thus developing qualified and satisfied faculty members. The aim of this study was to determine if participation in the training program improved the participants' satisfaction and competence in comparison to their colleagues who did not participate in the program. Two cohorts were compared: a control group of part-time faculty members who did not receive formal training when they were hired (n=21; response rate 58.3%); and the intervention group, who had participated in the NCFT program (n=12; response rate 80%). A survey of faculty members in the control group gathered information on their experiences when initially hired, and a pretest was administered to measure their knowledge of clinical policies. After the control group was given an overview of the program, their feedback was collected through post surveys, and a posttest identical to the pretest was given that found statistically significant increases on questions one (p=0.003) and four (p=0.025). In February 2014, 15 new faculty members participated in the pilot implementation of the NCFT program. Of those 15, 12 (the intervention group) completed follow-up surveys identical to the pre survey used with the control group. Statistically significant differences were found for the factors clinical teaching (p=0.005) and assessment training (p=0.008) with better responses for the NCFT group. These results suggest that participation in the program was associated with improved clinical teaching knowledge and job satisfaction.

    In this fourth part of the four-part TNS Draft Program Plan, project engineering concerns are considered. The TNS Project is first broken down into the major time and functional periods of feasibility study, preconceptual design, conceptual design, and line item construction, while the elements of the project are organized into an administrative work breakdown structure. With the aid of these two classifying schemes, the project tasks are described in terms of schedule, estimated cost, type of funding, and proposed type of participant. The initial constraints of completion data, anticipated scientific inputs, and budget procedures are used to develop a two-phase project in which the facilities are authorized first and the device 2 years later. This specific mechanism is fundamental to the construction of the schedule and should be reconsidered when the completion and initiation dates are reformulated

    2016-04-01

    If aging is a physiological phenomenon-as maintained by the programmed aging paradigm-it must be caused by specific genetically determined and regulated mechanisms, which must be confirmed by evidence. Within the programmed aging paradigm, a complete proposal starts from the observation that cells, tissues, and organs show continuous turnover: As telomere shortening determines both limits to cell replication and a progressive impairment of cellular functions, a progressive decline in age-related fitness decline (i.e., aging) is a clear consequence. Against this hypothesis, a critic might argue that there are cells (most types of neurons) and organ parts (crystalline core and tooth enamel) that have no turnover and are subject to wear or manifest alterations similar to those of cells with turnover. In this review, it is shown how cell types without turnover appear to be strictly dependent on cells subjected to turnover. The loss or weakening of the functions fulfilled by these cells with turnover, due to telomere shortening and turnover slowing, compromises the vitality of the served cells without turnover. This determines well-known clinical manifestations, which in their early forms are described as distinct diseases (e.g., Alzheimer's disease, Parkinson's disease, age-related macular degeneration, etc.). Moreover, for the two organ parts (crystalline core and tooth enamel) without viable cells or any cell turnover, it is discussed how this is entirely compatible with the programmed aging paradigm.

    1989-01-01

    The ACR-program (Automatic Finite Element Model Generation for Part Through Cracks) has been developed at the Technical Research Centre of Finland (VTT) for automatic finite element model generation for surface flaws using three dimensional solid elements. Circumferential or axial cracks can be generated on the inner or outer surface of a cylindrical or toroidal geometry. Several crack forms are available including the standard semi-elliptical surface crack. The program can be used in the development of automated systems for fracture mechanical analyses of structures. The tests for the accuracy of the FE-mesh have been started with two-dimensional models. The results indicate that the accuracy of the standard mesh is sufficient for practical analyses. Refinement of the standard mesh is needed in analyses with high load levels well over the limit load of the structure

    Environmental studies and environmental sciences programs in American and Canadian colleges and universities seek to ameliorate environmental problems through empirical enquiry and analytic judgment. In a companion article (Part 1) we describe the environmental program movement (EPM) and discuss factors that have hindered its performance. Here, we complete our analysis by proposing strategies for improvement. We recommend that environmental programs re-organize around three principles. First, adopt as an overriding goal the concept of human dignity—defined as freedom and social justice in healthy, sustainable environments. This clear higher-order goal captures the human and environmental aspirations of the EPM and would provide a more coherent direction for the efforts of diverse participants. Second, employ an explicit, genuinely interdisciplinary analytical framework that facilitates the use of multiple methods to investigate and address environmental and social problems in context. Third, develop educational programs and applied experiences that provide students with the technical knowledge, powers of observation, critical thinking skills and management acumen required for them to become effective professionals and leaders. Organizing around these three principles would build unity in the EPM while at the same time capitalizing on the strengths of the many disciplines and diverse local conditions involved.

    During the first two years of the program, studies were made of the water column extending from the seabed to the surface in mid-gyre regions. It was concluded that this water column is unsuitable for consideration as the disposal medium. Studies were shifted to characterization of the mid-plate, mid-gyre sediments, natural processes in the sediments, and how these natural processes are altered or impacted by the presence of high-level radioactive wastes. These activities continued in the third year of the Program and include (1) development of a number of analytical models as part of the overall systems analysis effort; (2) an extensive program to evaluate the sorption properties of the sediments with respect to single species ions and the competition provided by other waste constituents; (3) an assessment of thermal problems associated with the radiogenic heat produced by the waste and its impact upon the physical and chemical properties of the sediments; (4) continued studies to characterize the sediments; (5) development of capabilities to investigate waste canister emplacement techniques; (6) corrosion studies to evaluate potential canister materials; (7) biological investigations in support of assessment studies addressing accident scenarios and environmental impact; and (8) development of an international program of scientific investigations and information exchange. At the end of the third year, available data indicate that studies should be continued on the concept of disposal in the seabed

  2. Mainland China: a national one-child program does not exist (part two).

    Science.gov (United States)

    Jowett, A J

    1989-10-01

    This is part 2 of a 2-part paper discussing mainland China's 1-child policy. In part 1, Jowett argues that a national 1-child program does not exist in China. Instead, China has a series of regional policies which vary between and within provinces. Part 2 discusses these variations in childbearing policy. 1 table contrasts the developed coastal province of Liaoning and the underdeveloped interior province of Guizhou. In Liaoning, more than 75% of the women are literate, and infant mortality is less that 20/1000. In Guizhou, fewer than 33% of the women are literate, and infant mortality is over 60/1000. The per capital gross national product is 4.5 times higher in Liaoning. The birth rate is almost 10 points higher and the fertility rate almost 2.5 times greater in Guizhou than in Liaoning. The defiance of the 1-child policy is partially linked to the shift in social values taking place in mainland China. A trend toward earlier marriage and earlier childbearing has contributed to the rising birth rates in the 1980s. Unlike the outcome of the student protests in Tiananmen Square, conflict over family size has generally been resolved in favor of individual wished rather than government objectives.

  3. Accounting for straight parts effects on elbow's flexibilities in a beam type finite element program

    Millard, A.

    1983-01-01

    An extension of Von Karman's theory is applied to the calculations of the flexibility factor of a pipe bend terminated by a straight part or a flange. This analysis is restricted to the linear elastic deformation behaviour under in plane bending.

    An extension of Von Karman's theory is applied to the calculations of the flexibility factor of a pipe bend terminated by a straight part or a flange. This analysis is restricted to the linear elastic deformation behaviour under in plane bending. Analytical solutions are given for the propagation of ovalization in the elbow and in the straight part. Considering the response of the piping structures, we note that the ovalization of the piping systems are reduced significantly when the straight parts or flanges effects are included. The results are presented in terms of global as well local flexibility factors. They have been compared to numerical results obtained by shell type finite element method.

    The outcome of aortic valve-sparing root reconstruction in Marfan syndrome was reviewed. Thirteen patients with Marfan syndrome underwent aortic valve-sparing root reconstruction for annuloaortic ectasia or aortic root dissection between 1994 and 1999. The grade of preoperative aortic regurgitation was I in 4, II in 2, III in 5, IV in 2 patients. The procedures of aortic valve-sparing were reimplantation in 7 and remodeling in 5 patients. There was no hospital and late death. Recurrence of aortic regurgitation greater than moderate grade developed in 1 patient immediately after the surgery and in the other 4 patients in the late stage. One patient of them required aortic valve replacement for it. Aortic valve-sparing root reconstruction is applicable in Marfan patients, although the indication should be cautious. Close observation is needed for recurrence of aortic regurgitation.

    Katz, Richard; Kleyner, Igor

    2011-01-01

    A technique has been devised to enable creation of a dynamic set of test points in an embedded digital electronic system. As a result, electronics contained in an application specific circuit [e.g., gate array, field programmable gate array (FPGA)] can be internally probed, even when contained in a closed housing during all phases of test. In the present technique, the test points are not fixed and limited to a small number; the number of test points can vastly exceed the number of buffers or pins, resulting in a compact footprint. Test points are selected by means of spare logic resources within the ASIC(s) and/or FPGA(s). A register is programmed with a command, which is used to select the signals that are sent off-chip and out of the housing for monitoring by test engineers and external test equipment. The register can be commanded by any suitable means: for example, it could be commanded through a command port that would normally be used in the operation of the system. In the original application of the technique, commanding of the register is performed via a MIL-STD-1553B communication subsystem.

    Since 1995 the Department of Community Dentistry of the University of Pretoria has been involved in the rendering of mobile primary oral health care services to children in the Hammanskraal area of Gauteng, South Africa, as part of their students' community-based training. Mokonyama Primary School was identified as the first school where a primary oral health care service could be rendered. The objective of this study was to evaluate the impact (outcomes) of a fissure sealant program on the dentition status of the school children. Seven years after the implementation of the program, the dentition status of children at Mokonyama was compared with that of a comparable group of children from the same area who were not exposed to the program. The results showed that the decayed, missing, and filled teeth in the primary dentition (dmft) in the six-year-old group in Mokonyama (1.74) did not differ significantly from the dmft (1.43) of the control group (p = 0.49). The decayed, missing, and filled teeth in the permanent dentition (DMFT) of 0.59 for the fifteen-year-old group in Mokonyama, however, differed significantly (p = 0.0001) from the DMFT of the control group (2.38). Fifteen-year-old children in Mokonyama had 75.2 percent fewer caries than their counterparts in the control group.

    The NEPP Program focuses on the reliability aspects of electronic devices (integrated circuits such as a processor in a computer). There are three principal aspects of this reliability: 1) Lifetime, inherent failure and design issues related to the EEE parts technology and packaging; 2) Effects of space radiation and the space environment on these technologies, and; 3) Creation and maintenance of the assurance support infrastructure required for mission success. The NEPP mission is to provide guidance to NASA for the selection and application of microelectronics technologies, to improve understanding of the risks related to the use of these technologies in the space environment, and to ensure that appropriate EEE parts research is performed to meet NASA mission assurance needs. NEPPs FY15 goals are to represent the NASA voice to the greater aerospace EEE parts community including supporting anti-counterfeit and trust, provide relevant guidance to cost-effective missions, aid insertion of advanced (and commercial) technologies, resolve unexpected parts issues, ensure access to appropriate radiation test facilities, and collaborate as widely as possible with external entities. In accordance with the changing mission profiles throughout NASA, the NEPP Program has developed a balanced portfolio of efforts to provide agency-wide assurance for not only traditional spacecraft developments, but also those in-line with the new philosophies emerging worldwide. In this presentation, we shall present an overview of this program and considerations for EEE parts assurance as applied to cost conscious missions.

    1975-06-01

    A summary of work during the past several years on SETL, a new programming language drawing its dictions and basic concepts from the mathematical theory of sets, is presented. The work was started with the idea that a programming language modeled after an appropriate version of the formal language of mathematics might allow a programming style with some of the succinctness of mathematics, and that this might ultimately enable one to express and experiment with more complex algorithms than are now within reach. Part I discusses the general approach followed in the work. Part II focuses directly on the details of the SETL language as it is now defined. It describes the facilities of SETL, includes short libraries of miscellaneous and of code optimization algorithms illustrating the use of SETL, and gives a detailed description of the manner in which the set-theoretic primitives provided by SETL are currently implemented.

    WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Incremental nerve-sparing techniques (NSTs) improve postoperative erectile function after robot-assisted radical prostatectomy (RARP). However, there are no studies to date that histologically confirm the surgeon intended NST. Thus, in the present study, we histologically confirmed that the surgeon performed the nerve preservation as his intended NSTs during RARP. Also, we found that there was more variability in fascia width outcome on the left side compared with the right. Therefore, when performing nerve preservation on the surgeon's non-dominant side, we need to pay more close attention. To confirm that the surgeon achieved true intended histological nerve sparing during robot-assisted radical prostatectomy (RARP) by studying RP specimens. To aid the novice robotic surgeon to develop the skills of RARP. Between June 2008 and May 2009, 122 consecutive patients underwent RARP by a single surgeon (K.K.B.). The degree of nerve sparing (wide resection [WR], interfascial nerve sparing [ITE-NS], intrafascial nerve sparing [ITR-NS]) on both sides was recorded. The posterior sectors of RP specimens from distal, mid, and proximal parts were evaluated. Fascia width (FW) of each position in RP specimens were compared across nerve-sparing types (NSTs). FW was recorded at 15 ° intervals (3-9 o'clock position), measured as the distance between the outermost prostate gland and surgical margin. The slides were reviewed by an experienced uropathologist who was 'blinded' to the NST. In all, 93 men were included. The overall mean (sd) FW was the greatest in the order of WR, ITE-NS, and ITR-NS, at 2.42 (1.62), 1.71 (1.40) and 1.16 (1.08) mm, respectively (P ITE-NS, bilateral ITE-NS, ITE-NS/WR, and bilateral WR, respectively. To further validate and confirm these preliminary findings, additional studies involving multicentre cohorts would be required. The surgeon intended dissection and FW correlate, with ITR

    Normal tissue toxicity is the dose-limiting side effect of radiotherapy. Spatial fractionation irradiation techniques, like microbeam radiotherapy (MRT), have shown promising results in sparing the normal brain tissue. Most MRT studies have been conducted at synchrotron facilities. With the aim to make this promising treatment more available, we have built the first desktop image-guided MRT device based on carbon nanotube x-ray technology. In the current study, our purpose was to evaluate the effects of MRT on the rodent normal brain tissue using our device and compare it with the effect of the integrated equivalent homogenous dose. Twenty-four, 8-week-old male C57BL/6 J mice were randomly assigned to three groups: MRT, broad-beam (BB) and sham. The hippocampal region was irradiated with two parallel microbeams in the MRT group (beam width = 300 μm, center-to-center = 900 μm, 160 kVp). The BB group received the equivalent integral dose in the same area of their brain. Rotarod, marble burying and open-field activity tests were done pre- and every month post-irradiation up until 8 months to evaluate the cognitive changes and potential irradiation side effects on normal brain tissue. The open-field activity test was substituted by Barnes maze test at 8th month. A multilevel model, random coefficients approach was used to evaluate the longitudinal and temporal differences among treatment groups. We found significant differences between BB group as compared to the microbeam-treated and sham mice in the number of buried marble and duration of the locomotion around the open-field arena than shams. Barnes maze revealed that BB mice had a lower capacity for spatial learning than MRT and shams. Mice in the BB group tend to gain weight at the slower pace than shams. No meaningful differences were found between MRT and sham up until 8-month follow-up using our measurements. Applying MRT with our newly developed prototype compact CNT-based image-guided MRT system

    Since the use of standard engineering methods in the process of an ice bank performance evaluation offers neither adequate flexibility nor accuracy, the aim of this research was to provide a powerful tool for an industrial design of an ice storage system allowing to account for the various design parameters and system arrangements over a wide range of time varying operating conditions. In this paper the development of a computer application for the prediction of an ice bank system operation is presented. Static, indirect, cool thermal storage systems with external ice on coil building/melting were considered. The mathematical model was developed by means of energy and mass balance relations for each component of the system and is basically divided into two parts, the model of an ice storage system and the model of a refrigeration unit. Heat transfer processes in an ice silo were modelled by use of empirical correlations while the performance of refrigeration unit components were based on manufacturers data. Programming and application design were made in Fortran 95 language standard. Input of data is enabled through drop down menus and dialog boxes, while the results are presented via figures, diagrams and data (ASCII) files. In addition, to demonstrate the necessity for development of simulation program a case study was performed. Simulation results clearly indicate that no simple engineering methods or rule of thumb principles could be utilised in order to validate performance of an ice bank system properly. (author)

    Benthic algae (periphyton) and phytoplankton communities are characterized in the U.S. Geological Survey's National Water-Quality Assessment Program as part of an integrated physical, chemical, and biological assessment of the Nation's water quality. This multidisciplinary approach provides multiple lines of evidence for evaluating water-quality status and trends, and for refining an understanding of the factors that affect water-quality conditions locally, regionally, and nationally. Water quality can be characterized by evaluating the results of qualitative and quantitative measurements of the algal community. Qualitative periphyton samples are collected to develop of list of taxa present in the sampling reach. Quantitative periphyton samples are collected to measure algal community structure within selected habitats. These samples of benthic algal communities are collected from natural substrates, using the sampling methods that are most appropriate for the habitat conditions. Phytoplankton samples may be collected in large nonwadeable streams and rivers to meet specific program objectives. Estimates of algal biomass (chlorophyll content and ash-free dry mass) also are optional measures that may be useful for interpreting water-quality conditions. A nationally consistent approach provides guidance on site, reach, and habitat selection, as well as information on methods and equipment for qualitative and quantitative sampling. Appropriate quality-assurance and quality-control guidelines are used to maximize the ability to analyze data locally, regionally, and nationally.

  10. Fractional Programming for Communication Systems—Part II: Uplink Scheduling via Matching

    Science.gov (United States)

    Shen, Kaiming; Yu, Wei

    2018-05-01

    This two-part paper develops novel methodologies for using fractional programming (FP) techniques to design and optimize communication systems. Part I of this paper proposes a new quadratic transform for FP and treats its application for continuous optimization problems. In this Part II of the paper, we study discrete problems, such as those involving user scheduling, which are considerably more difficult to solve. Unlike the continuous problems, discrete or mixed discrete-continuous problems normally cannot be recast as convex problems. In contrast to the common heuristic of relaxing the discrete variables, this work reformulates the original problem in an FP form amenable to distributed combinatorial optimization. The paper illustrates this methodology by tackling the important and challenging problem of uplink coordinated multi-cell user scheduling in wireless cellular systems. Uplink scheduling is more challenging than downlink scheduling, because uplink user scheduling decisions significantly affect the interference pattern in nearby cells. Further, the discrete scheduling variable needs to be optimized jointly with continuous variables such as transmit power levels and beamformers. The main idea of the proposed FP approach is to decouple the interaction among the interfering links, thereby permitting a distributed and joint optimization of the discrete and continuous variables with provable convergence. The paper shows that the well-known weighted minimum mean-square-error (WMMSE) algorithm can also be derived from a particular use of FP; but our proposed FP-based method significantly outperforms WMMSE when discrete user scheduling variables are involved, both in term of run-time efficiency and optimizing results.

  11. Clinic-radiology findings at limp-sparing surgery of alveolar sarcoma

    International Nuclear Information System (INIS)

    Tzekov, A.; Penchev, V.; Niagolova, S.; Kovachev, V.

    2007-01-01

    Soft-tissue sarcomas are a rare and heterogeneous group of tumors. Alveolar soft part sarcoma is a rare sarcoma of an unclear cause. It is representing 0.2-1 percent of soft tissue sarcomas. Unique biologic behaviors of soft-tissue sarcomas features include formation of a reactive zone, intra-compartmental growth, and, rarely, the presence of skip metastases. Although the soft-tissue sarcomas have a unique morphology, biological behavior, and prognosis, they share biological characteristics and are treated in a similar fashion. The concept of limb-sparing surgery, or limb salvage, has gradually evolved over the past 25 years. Prior to this the basic principles of surgical oncology for the extremities consisted solely of determining the correct level at which to perform an amputation. The three stages of a limb-sparing procedure are as follows: tumor resection skeletal reconstruction and soft-tissue coverage and muscle transfers to restore function. Imaging diagnostic is a key step in the limp-sparing surgery of a soft tissue sarcomas at relation of: preoperatively - the diagnosis of lesion, the decision for biopsy, about location of the lesion and what is the safest anatomic route to that location, possibly lung and bone metastases; postoperative - checking the position of the prosthesis, inflammatory, mechanic and oncology complications.

  14. Independent oversight review of the Department of Energy Quality Assurance Program for suspect/counterfeit parts. Revision 1

    International Nuclear Information System (INIS)

    1996-05-01

    To address the potential threat that suspect/counterfeit parts could pose to DOE workers and the public, the Office of the Deputy Assistant Secretary for Oversight initiated a number of activities beginning in mid-1995. Oversight placed increased emphasis on the field's quality assurance-suspect/counterfeit parts programs during safety management evaluations, in keeping with the Office of Environment, Safety and Health (EH) oversight responsibilities, which include oversight of the Department's quality assurance (QA) programs. In addition, Oversight reviewed relevant policy documents and occurrence reports to determine the nature and magnitude of the problem within the Department.

    To address the potential threat that suspect/counterfeit parts could pose to DOE workers and the public, the Office of the Deputy Assistant Secretary for Oversight initiated a number of activities beginning in mid-1995. Oversight placed increased emphasis on the field`s quality assurance-suspect/counterfeit parts programs during safety management evaluations, in keeping with the Office of Environment, Safety and Health (EH) oversight responsibilities, which include oversight of the Department`s quality assurance (QA) programs. In addition, Oversight reviewed relevant policy documents and occurrence reports to determine the nature and magnitude of the problem within the Department. The results of that review, contained in an Office of Oversight report, Independent Oversight Analysis of Suspect/Counterfeit Parts Within the Department of Energy (November 1995), indicate a lack of consistency and comprehensiveness in the Department`s QA-suspect/counterfeit parts program. A detailed analysis of the causes and impacts of the problem was recommended. In response, this review was initiated to determine the effectiveness of the Department`s QA program for suspect/counterfeit parts. This study goes beyond merely assessing and reporting the status of the program, however. It is the authors intention to highlight the complex issues associated with suspect/counterfeit parts in the Department today and to present approaches that DOE managers might consider to address these issues.

    The aim of this article is to describe the development and testing of a prototype application ("The Heart Game") using gamification principles to assist heart patients in their telerehabilitation process in the Teledialog project. A prototype game was developed via user-driven innovation and tested on 10 patients 48-89 years of age and their relatives for a period of 2 weeks. The application consisted of a series of daily challenges given to the patients and relatives and was based on several gamification principles. A triangulation of data collection techniques (interviews, participant observations, focus group interviews, and workshop) was used. Interviews with three healthcare professionals and 10 patients were carried out over a period of 2 weeks in order to evaluate the use of the prototype. The heart patients reported the application to be a useful tool as a part of their telerehabilitation process in everyday life. Gamification and gameful design principles such as leaderboards, relationships, and achievements engaged the patients and relatives. The inclusion of a close relative in the game motivated the patients to perform rehabilitation activities. "The Heart Game" concept presents a new way to motivate heart patients by using technology as a social and active approach to telerehabilitation. The findings show the potential of using gamification for heart patients as part of a telerehabilitation program. The evaluation indicated that the inclusion of the patient's spouse in the rehabilitation activities could be an effective strategy. A major challenge in using gamification for heart patients is avoiding a sense of defeat while still adjusting the level of difficulty to the individual patient.

    Lewellen, J. W.

    1999-01-01

    Last year a second-generation SSRL-type thermionic cathode rf gun was installed in the Advanced Photon Source (APS) linac. This gun (referred to as ''gun2'') has been successfully commissioned and now serves as the main injector for the APS linac, essentially replacing the Koontz-type DC gun. To help ensure injector availability, particularly with the advent of top-up mode operation at the APS, a second thermionic-cathode rf gun will be installed in the APS linac to act as a hot-spare beam source. The hot-spare installation includes several unique design features, including a deep-orbit Panofsky-style alpha magnet. Details of the hot-spare beamline design and projected performance are presented, along with some plans for future performance upgrades

    The Spallation Neutron Source (SNS) Central Helium Liquefier (CHL) at Oak Ridge National Laboratory (ORNL) has been without major operations downtime since operations were started back in 2006. This system utilizes a vessel filled with activated carbon as the final major component to remove oil vapor from the compressed helium circuit prior to insertion into the system's cryogenic cold box. The need for a spare carbon bed at SNS due to the variability of carbon media lifetime calculation to adsorption efficiency will be discussed. The fabrication, installation and commissioning of this spare carbon vessel will be presented. The novel plan for connecting the spare carbon vessel piping to the existing infrastructure will be presented.

    Valve-sparing root replacement is increasingly used to overcome drawbacks associated with valvular prostheses. In our institution, 7 patients underwent valve-sparing root replacement from August 2016 to July 2017. The mean age was 45 years (range, 14~69 years). Three patients had Marfan syndrome and 1 had Loeys-Dietz syndrome with acute aortic dissection. All patients underwent surgery with reimplantation technique using a Valsalva graft. Two patients required repair of aortic valve leaflet prolapse. All patients had an excellent clinical course, with mild or no aortic regurgitation and a decrease in end-diastolic volume on echocardiography. These results support the continued use of valve-sparing root replacement in selected patients.

    International Nuclear Information System (INIS)

    1985-06-01

    The Misson Plan is divided into two parts. Part I describes the overall goals, objectives, and strategy for the disposal of spent nuclear fuel and high-level waste. It explains that, to meet the directives of the Nuclear Waste Policy Act, the DOE intends to site, design, construct, and start operating a mined geologic repository by January 31, 1998. The Act specifies that the costs of these activities will be borne by the owners and generators of the waste received at the repository. Part I further describes the other components of the waste-management program - monitored retrievable storage, Federal interim storage, and transportation - as well as systems integration activities. Also discussed are institutional plans and activities as well as the program-management system being implemented by the Office of Civilian Radioactive Waste Management. Part II of the Mission Plan presents the detailed information required by Section 301(a) of the Act - key issues and information needs; plans for obtaining the necessary information; potential financial, institutional, and legal issues; plans for the test and evaluation facility; the principal results obtained to date from site investigations; information on the site-characterization programs; information on the waste package; schedules; costs; and socioeconomic impacts. In accordance with Section 301(a) of the Act, Part II is concerned primarily with the repository program

    2008-01-01

    Knowing where the tumor is at all times during treatment is the next challenge in the field of radiation therapy. This issue has become more important because with treatments such as Intensity Modulated Radiation Therapy (IMRT), healthy tissue is spared by using very tight margins around the tumor. These tight margins leave very small room for patient setup errors. The use of an imaging modality in the treatment room as a way to localize the tumor for patient set up is generally known as ''Image Guided Radiation Therapy'' or IGRT. This article deals with a form of IGRT known as Megavoltage Cone Beam Computed Tomography (MCBCT) using a Siemens Oncor linear accelerator currently in use at Firelands Regional Medical Center. With MCBCT, we are capable of acquiring CT images right before the treatment of the patient and then use this information to position the patient tumor according to the treatment plan. This article presents the steps followed in order to clinically implement this system, as well as some of the quality assurance tests suggested by the manufacturer and some tests developed in house

  5. A bi-objective integer programming model for partly-restricted flight departure scheduling.

    The normal studies on air traffic departure scheduling problem (DSP) mainly deal with an independent airport in which the departure traffic is not affected by surrounded airports, which, however, is not a consistent case. In reality, there still exist cases where several commercial airports are closely located and one of them possesses a higher priority. During the peak hours, the departure activities of the lower-priority airports are usually required to give way to those of higher-priority airport. These giving-way requirements can inflict a set of changes on the modeling of departure scheduling problem with respect to the lower-priority airports. To the best of our knowledge, studies on DSP under this condition are scarce. Accordingly, this paper develops a bi-objective integer programming model to address the flight departure scheduling of the partly-restricted (e.g., lower-priority) one among several adjacent airports. An adapted tabu search algorithm is designed to solve the current problem. It is demonstrated from the case study of Tianjin Binhai International Airport in China that the proposed method can obviously improve the operation efficiency, while still realizing superior equity and regularity among restricted flows.

  6. Cognitive Spare Capacity and Speech Communication: A Narrative Overview

    2014-01-01

    Full Text Available Background noise can make speech communication tiring and cognitively taxing, especially for individuals with hearing impairment. It is now well established that better working memory capacity is associated with better ability to understand speech under adverse conditions as well as better ability to benefit from the advanced signal processing in modern hearing aids. Recent work has shown that although such processing cannot overcome hearing handicap, it can increase cognitive spare capacity, that is, the ability to engage in higher level processing of speech. This paper surveys recent work on cognitive spare capacity and suggests new avenues of investigation.

    Massive hydraulic fracture mapping field experiments continued in FY 77 with Sandia participating in fractures with Gas Producing Enterprises, Amoco, Shell, and Conoco. The surface electrical potential system has demonstrated that the fracture orientation can be determined to within +- 5/sup 0/ and has clearly shown that most fractures are asymmetrical. This system has been completely documented and has had wide exposure to the industry providing for the transfer of its technology. Improvements in the electrical system, its analytical model and the development of new systems for fracture diagnostics was also continuing. Hydraulic and explosive fracturing experiments have been conducted adjacent to an existing tunnel complex at DOE's Nevada Test Site and have been directly observed by subsequent mineback activities. Evaluation of a proppant distribution experiment has revealed a very complex fracture system which differed significantly from design; additional in situ stress and material property measurements are being made to quantify observed behavior. An experiment has been designed and conducted which will examine hydraulic fracture behavior at a geologic interface between formations with significantly different moduli, Poisson's ratios and porosities; mineback evaluation will occur next year. In conjunction wth a nuclear containment program, the stresses surrounding a contained explosive detonation have been examined. A 256 lb TNT detonation produced no radial fractures extending from the main cavity, but gases escaping down a borehole did create a 30 x 75 ft fracture in a region of reduced overburden stress caused by the explosion. Specific aid was provided in the planning and development of the Western Tight Gas Sands Project and DOE's Enhanced Gas Recovery Strategy Plan. A resource survey of the Greater Green River Basin was conducted as part of the latter activity.

  12. Muscle sparing lateral thoracotomy: the standard incision for thoracic procedures

    Directory of Open Access Journals (Sweden)

    Mihai Dumitrescu

    2017-05-01

    Full Text Available Lateral thoracotomy is a versatile approach with many variations and is currently the most widely used incision in thoracic surgery. In the current article we are presenting the muscle-sparing lateral thoracotomy in the lateral decubitus position which we consider to be the “standard” for lateral thoracotomies. Indications, surgical technique and pitfalls are described alongside our experience with thoracic drainage. Although there is no consensus regarding the name of this incision, some authors call it “axillary thoracotomy” while others call it a “modified lateral thoracotomy”, they all agree on one aspect – the importance of muscle sparing – which makes it the go-to thoracotomy for both small and large procedures involving the lung. Lateral muscle sparing thoracotomy allows for good exposure of the pulmonary hilum, fissures, apex and diaphragm. The approach is easy and quick to perform while at the same time ensuring faster postoperative recovery by sparing the latissimus dorsi muscle, better cosmetics and lower postoperative pain score when compared to the posterolateral or classical lateral thoracotomies.

    2017-11-01

    This qualitative study is part of a mixed methods research project that examined the effectiveness of the primary rehabilitation program for domestic violence offenders in the Israeli Prison Services-the "House of Hope." The quantitative part of the study showed that the "House of Hope" program was effective in reducing recidivism among participating inmates. The purpose of this qualitative study was to describe the rehabilitation program according to the perspectives of the program staff. For this purpose, semistructured interviews were conducted with the department staff during the study as well as with past directors. The qualitative findings suggested that the success of the program probably stemmed from a synergistic combination of several components, for example, identifying the characteristics of domestic violence offenders and adjusting treatment programs to their needs, along with exposure to psychological treatment in varied therapies (cognitive behavioral therapy, psychoeducational, and psychodynamic) and formats (group therapy and individual therapy) during a 1-year stay in a hierarchical therapeutic community. Other components mentioned are staff professionalism, stability, and the program's location in a therapeutic-oriented prison that is architecturally designed and built to create a less stressful environment for the inmates and the staff.

    2014-12-01

    The Centers for Medicare Medicaid Services (CMS) Plan Quality and Performance Program, or Star Ratings Program, allows Medicare beneficiaries to compare quality of care among available Medicare Advantage prescription drug (MA-PD) plans and stand-alone prescription drug plans (PDPs). Health plans have increased intervention efforts and applied existing care management infrastructure as an approach to improving member medication adherence and subsequent Part D star rating performance. Independent Care Health Plan (iCare), an MA-PD plan; MedImpact Healthcare Systems, Inc. (MedImpact), a pharmacy benefits manager; and US MED, a mail order pharmacy, partnered to engage and enroll iCare's dual-eligible special needs population in an intervention designed to improve patient medication adherence and health plan performance for 3 Part D patient safety outcome measures: Medication Adherence for Oral Diabetes Medications (ODM), Medication Adherence for Hypertension (HTN), and Medication Adherence for Cholesterol (CHOL). To (a) assess the effectiveness of a coordinated member-directed medication adherence intervention and (b) determine the overall impact of the intervention on adherence rates and CMS Part D star rating adherence measures.  Administrative pharmacy claims and health plan eligibility data from MedImpact's databases were used to identify members using 3 target medication classes. Adherence was estimated by the proportion of days covered (PDC) for all members. Those members considered at high risk for nonadherence were prioritized for care management services. Risk factors were based on members' use of more than 1 target medication class, newly started therapy, and suboptimal adherence (PDC  less than  80%) in the most recent 6-month period. Data files listing member adherence rates and contact information were formatted and loaded monthly into iCare's care management system, which triggered an alert for care coordinators to counsel members on the importance

  5. Element Partition Trees For H-Refined Meshes to Optimize Direct Solver Performance. Part I: Dynamic Programming

    KAUST Repository

    AbouEisha, Hassan M.

    2017-07-13

    We consider a class of two-and three-dimensional h-refined meshes generated by an adaptive finite element method. We introduce an element partition tree, which controls the execution of the multi-frontal solver algorithm over these refined grids. We propose and study algorithms with polynomial computational cost for the optimization of these element partition trees. The trees provide an ordering for the elimination of unknowns. The algorithms automatically optimize the element partition trees using extensions of dynamic programming. The construction of the trees by the dynamic programming approach is expensive. These generated trees cannot be used in practice, but rather utilized as a learning tool to propose fast heuristic algorithms. In this first part of our paper we focus on the dynamic programming approach, and draw a sketch of the heuristic algorithm. The second part will be devoted to a more detailed analysis of the heuristic algorithm extended for the case of hp-adaptive

    One of the main problems encountered by the oil extraction industry, is the reduction of the local permeability of the rock formation near the extraction wells because of salt deposition in the pores of the rocks during the injection of brine water to displace the trapped oil ganglia within the oil formations. This phenomenon makes the oil recovery less efficient and under extreme cases the well is abandoned with a large amount of oil entrapped. Several detailed studies have been conducted in the past concerning sand bed consolidation using sparingly soluble salts for varying conditions (e.g. temperature, grain size, sand type, salt concentrations etc) and various salts [1]. Nevertheless, salt precipitation in the rock formation pores under the presence of other miscible or immiscible substances with water has not been investigated in details yet. In the present study, salt (CaCO3) precipitation experiments were performed in small beds packed with sea sand mixed with a low amount of CaCO3 seed grains. The experiments were performed using pure solutions (NaHCO3, CaCl2.2H2O) and solutions mixed with Ethylene Glycol in sand beds. Additionally, precipitation experiments were performed using pure solutions in sand beds saturated with oil phase (n-dodecane) for a wide range of solution supersaturation. During the experiments the ionic strength was kept constant. pH and concentration values of calcium ion of the effluent were measured and the precipitated salt crystals were identified using X-ray Diffraction (XRD) method. At the end of each experiment Scanning Electron Microscope (SEM) was conducted using a sample of the precipitated sand to identify the morphology of the precipitated crystals and their cohesion with sand grains.

  17. Analytical studies by activation. Part A and B: Counting of short half-life radio-nuclides. Part C: Analytical programs for decay curves

    International Nuclear Information System (INIS)

    Junod, E.

    1966-03-01

    Part A and B: Since a radio-nuclide of short half-life is characterized essentially by the decrease in its activity even while it is being measured, the report begins by recalling the basic relationships linking the half-life the counting time, the counting rate and the number of particles recorded. The second part is devoted to the problem of corrections for counting losses due to the idle period of multichannel analyzers. Exact correction formulae have been drawn up for the case where the short half-life radionuclide is pure or contains only a long half-life radio-nuclide. By comparison, charts have been drawn up showing the approximations given by the so-called 'active time' counting and by the counting involving the real time associated with a measurement of the overall idle period, this latter method proving to be more valid than the former. A method is given for reducing the case of a complex mixture to that of a two-component mixture. Part C: The problems connected with the qualitative and quantitative analysis of the decay curves of a mixture of radioactive sources of which one at least has a short half-life are presented. A mathematical description is given of six basic processes for which some elements of Fortran programs are proposed. Two supplementary programs are drawn up for giving an overall treatment of problems of dosage in activation analysis: one on the basis of a simultaneous irradiation of the sample and of one or several known samples, the other with separate irradiation of the unknown and known samples, a dosimeter (activation, or external) being used for normalizing the irradiation flux conditions.

    The environmental sciences/studies movement, with more than 1000 programs at colleges and universities in the United States and Canada, is unified by a common interest-ameliorating environmental problems through empirical enquiry and analytic judgment. Unfortunately, environmental programs have struggled in their efforts to integrate knowledge across disciplines and educate students to become sound problem solvers and leaders. We examine the environmental program movement as a policy problem, looking at overall goals, mapping trends in relation to those goals, identifying the underlying factors contributing to trends, and projecting the future. We argue that despite its shared common interest, the environmental program movement is disparate and fragmented by goal ambiguity, positivistic disciplinary approaches, and poorly rationalized curricula, pedagogies, and educational philosophies. We discuss these challenges and the nature of the changes that are needed in order to overcome them. In a subsequent article (Part 2) we propose specific strategies for improvement. ?? 2011 Springer Science+Business Media, LLC.

    2011-01-01

    Purpose To assess whether in addition to sparing parotid glands (PGs), xerostomia after chemo-IMRT of head and neck cancer is affected by reducing doses to other salivary glands. Methods Prospective study: 78 patients with stages III/IV oropharynx/nasopharynx cancers received chemo-IMRT aiming to spare the parts outside the targets of bilateral PGs, oral cavity (OC) containing the minor salivary glands, and contralateral submandibular gland (SMG) (when contralateral level I was not a target). Pretherapy and periodically through 24 months, validated patient-reported xerostomia questionnaires (XQ) scores and observer-graded xerostomia were recorded, and stimulated and unstimulated saliva measured selectively from each of the PGs and SMGs. Mean OC doses served as surrogates of minor salivary glands dysfunction. Regression models assessed XQ and observer-graded xerostomia predictors. Results Statistically significant predictors of the XQ score in univariate analysis included OC, PG, and SMG mean doses, as well as baseline XQ score, time since RT, and both stimulated and unstimulated PG saliva flow rates. Similar factors were statistically significant predictors of observer-graded xerostomia. OC, PG and SMG mean doses were moderately inter-correlated (r=0.47–0.55). In multivariate analyses, after adjusting for PG and SMG doses, OC mean dose (p xerostomia. While scatter plots showed no thresholds, OC mean doses xerostomia at almost all post-therapy time points. Conclusion PG, SMG and OC mean doses were significant predictors of both patient-reported and observer-rated xerostomia after chemo-IMRT, with OC doses remaining significant after adjusting for PG and SMG doses. These results support efforts to spare all salivary glands by IMRT, beyond the PGs alone. PMID:22056067

  20. Comparison of Spares Logistics Analysis Techniques for Long Duration Human Spaceflight

    As the durations and distances involved in human exploration missions increase, the logistics associated with the repair and maintenance becomes more challenging. Whereas the operation of the International Space Station (ISS) depends upon regular resupply from the Earth, this paradigm may not be feasible for future missions. Longer mission durations result in higher probabilities of component failures as well as higher uncertainty regarding which components may fail, and longer distances from Earth increase the cost of resupply as well as the speed at which the crew can abort to Earth in the event of an emergency. As such, mission development efforts must take into account the logistics requirements associated with maintenance and spares. Accurate prediction of the spare parts demand for a given mission plan and how that demand changes as a result of changes to the system architecture enables full consideration of the lifecycle cost associated with different options. In this paper, we utilize a range of analysis techniques - Monte Carlo, semi-Markov, binomial, and heuristic - to examine the relationship between the mass of spares and probability of loss of function related to the Carbon Dioxide Removal System (CRS) for a notional, simplified mission profile. The Exploration Maintainability Analysis Tool (EMAT), developed at NASA Langley Research Center, is utilized for the Monte Carlo analysis. We discuss the implications of these results and the features and drawbacks of each method. In particular, we identify the limitations of heuristic methods for logistics analysis, and the additional insights provided by more in-depth techniques. We discuss the potential impact of system complexity on each technique, as well as their respective abilities to examine dynamic events. This work is the first step in an effort that will quantitatively examine how well these techniques handle increasingly more complex systems by gradually expanding the system boundary.

    CLAS (C Language Program Analysis System) is a reverse engineering tool intended for use in the verification and validation (V and V) phase of software programs developed in the ANSI C language. From the source code, CLAS generates data pertaining to two conceptual models of software programs viz., Entity-Relationship (E-R) model and Control Flow Graphs (CFG) model. Browsing tools within CLAS, make use of this data, to provide different graphical views of the project. Static analysis tools have been developed earlier for analysing assembly language programs. CLAS is a continuation of this work to provide automated support in analysis of ANSI C language programs. CLAS provides an integrated Graphical User Interface (GUI) based environment under which programs can be analysed into the above mentioned models and the analysed data can be viewed using the browsing tools. The GUI of CLAS is implemented using an OPEN LOOK compliant tool kit XVIEW on Sun SPARC IPC workstation running Sun OS 4.1.1 rev. B. This report describes the GUI of CLAS. CLAS is also expected to be useful in other contexts which may involve understanding architecture/structure of already developed C language programs. Such requirements can arise while carrying out activities like code modification, parallelising etc. (author). 5 refs., 13 figs., 1 appendix

  2. A systematic writing program as a tool in the grief process: part 1.

    Furnes, Bodil; Dysvik, Elin

    2010-12-06

    The basic aim of this paper is to suggest a flexible and individualized writing program as a tool for use during the grief process of bereaved adults. An open, qualitative approach following distinct steps was taken to gain a broad perspective on the grief and writing processes, as a platform for the writing program. Following several systematic methodological steps, we arrived at suggestions for the initiation of a writing program and its structure and substance, with appropriate guidelines. We believe that open and expressive writing, including free writing and focused writing, may have beneficial effects on a person experiencing grief. These writing forms may be undertaken and systematized through a writing program, with participation in a grief writing group and with diary writing, to achieve optimal results. A structured writing program might be helpful in promoting thought activities and as a tool to increase the coherence and understanding of individuals in the grief process. Our suggested program may also be a valuable guide to future program development and research.

    The Drug Usage Guidelines (DUG) program, as perceived by the members of the P & T Committee and by physicians who had prepared and submitted DUGs, was demonstrated to be an effective method for evaluating drugs for formulary inclusion. The majority of P & T members felt that the DUG program had strengthened the drug review process without being too tedious or preventing the addition of valuable drugs to the formulary. Sixty-eight percent of physicians who had submitted a DUG expressed the opinion that it served as a vehicle for providing educational information on rational therapeutics. A majority of respondents stated that they would recommend the DUG program to other hospitals.

    1977-10-01

    A draft program plan for TNS has been prepared which consists of two basic parts--an R and D Needs Assessment and a Project Plan with schedules and necessary implementation steps. In this brief but intensive effort, questions concerning (1) the present basis for the TNS program, (2) the principal gaps in the supporting program, and (3) the necessary actions to be taken to implement the TNS program were examined. The study supported the thesis that the physics and technology bases do exist from which to start the TNS design as a central fusion program goal. Specific recommendations are made to emphasize those physics, technology, and engineering areas in which there are program gaps. In the project engineering study, a basic schedule with close support from the R and D program is developed from which recommendations on administrative actions and areas for further elucidation are made. This document presents in summary form the findings of the study, the development of the principal theses, and the recommendation to ERDA-DMFE

    2011-09-01

    Full Text Available The objective of the present study was to evaluate carcass and parts' yield, abdominal fat deposition and breast and foot pad blisters of broilers reared under two lighting programs (nearly continuous or intermittent in broilers houses with yellow and blue curtains. The experiment was conducted between June, 2004 and May, 2005. Six flocks were sequentially housed in four 12 × 10 m broiler houses divided into 4 pens with 200 birds each. The litter was reused six times or until flock 6. A completely randomized design in a 6 × 2 × 2 factorial arrangement (flocks, lighting programs, curtains with four replicates per treatment was applied. A total of 288 birds were evaluated for carcass yield. Curtain color did not affect carcass or parts' yield. The effect of lighting program and curtain color on carcass yield may depend on other factors related to flock. Intermittent lighting program promoted the highest drumstick and thigh yields. Lighting programs and curtain colors did not affect abdominal fat deposition or the presence of breast and foot pad blisters.

    Mutant mitochondrial DNA gives rise to a broad range of incurable inborn maladies. Prevention may now be possible by replacing the mutation-carrying mitochondria of zygotes or oocytes at risk with donated unaffected counterparts. However, mitochondrial replacement therapy is being held back by theological, ethical, and safety concerns over the loss of human zygotes and the involvement of a donor. These concerns make it plain that the identification, validation, and regulatory adjudication of novel embryo-sparing donor-independent technologies remains a pressing imperative. This Opinion highlights three emerging embryo-sparing donor-independent options that stand to markedly allay theological, ethical, and safety concerns raised by mitochondrial replacement therapy.

    Chen, Kemin; Hiramatsu, Yoshihiro; Yunoki, Masanori; Hirano, Yoko

    1989-01-01

    In evaluating fatty liver with CT, the residual normal liver tissues without fat deposits are occasionally detected on CT as high attenuation regions, especially surrounding the gallbladder. This study examined the incidence of this phenomenon in terms of the diagnostic value of CT in fatty liver. Fifty-seven patients with fatty liver were examined with CT. The incidence of focal sparing area was the highest in the gallbladder bed (42/57, 74%), followed by the interlobar fissure or subcapsular area (13, 23%), quadrate lobe (8, 14%), caudate lobe (2, 4%), and right lobe (one, 1.8%). These CT appearances were of spot, band, ring, and the mixed type. In 38 patients, fatty liver was too moderate to be detected without CT attenuation numbers. Among them, 27 patients (71%) had focal sparing area surrounding the gallbladder. This CT appearance seemed to be of significance in preventing the missing of moderate fatty liver. (Namekawa, K)

    2014-01-01

    Radiation treatment techniques for whole-brain radiation therapy (WBRT) have not changed significantly since development of the procedure. However, the recent development of novel techniques such as intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT) and helical tomotherapy, as well as an increasing body of evidence concerning neural stem cells (NSCs) have altered the conventional WBRT treatment paradigm. In this regard, hippocampus-sparing WBRT is a novel technique that aims to spare critical hippocampus regions without compromising tumour control. Published data on this new technique are limited to planning and feasibility studies; data on patient outcome are still lacking. However, several prospective trials to analyse the feasibility of this technique and to document clinical outcome in terms of reduced neurotoxicity are ongoing. (orig.) [de

    This paper presents the results of theory-based intervention strategies to increase the adoption of a tobacco prevention program. The adoption intervention followed a series of dissemination intervention strategies targeted at 128 school districts in Texas. Informed by Social Cognitive Theory, the intervention provided opportunities for districts to learn about and model themselves after 'successful' school districts that had adopted the program, and to see the potential for social reinforcement through the knowledge that the program had the potential to have an important influence on students' lives. The proportion of districts in the Intervention condition that adopted the program was significantly greater than in the Comparison condition (P teacher attitudes toward the innovation and organizational considerations of administrators. Recommendations for the development of effective strategies for the diffusion of innovations are presented.

    Stefaniak, B.

    2002-01-01

    As described earlier, a dedicated computer program was developed for quantitative evaluation of regional lung perfusion defects, visualized by pulmonary scintigraphy. The correctness of the basic assumptions accepted to construct the algorithms and of the all program functions needed to be checked, before application of the program into the clinical routine. The aim of this study was to verified the program using various software instruments and physical models. Evaluation of the proposed method was performed using software procedures, physical lung phantom, and selected lung image.The reproducibility of lung regions, defined by the program was found excellent. No significant distortion of registered data was observed after ROI transformation into the circle and retransformation into the original shape. The obtained results comprised parametric presentation of activity defects as well as a set of numerical indices which defined extent and intensity of decreased counts density. Among these indices PD2 and DM* were proved the most suitable for the above purposes. The obtained results indicate that the algorithms used for the program construction were correct and suitable for the aim of the study. The above algorithms enable function under study to be presented graphically with true imaging of activity distribution, as well as numerical indices, defining extent and intensity of activity defects to calculated.

    Objectives. To implement and evaluate a 3-year reflective writing program incorporated into introductory pharmacy practice experiences (IPPEs) in the first- through third-year of a doctor of pharmacy (PharmD) program. Design. Reflective writing was integrated into 6 IPPE courses to develop students’ lifelong learning skills. In their writing, students were required to self-assess their performance in patient care activities, identify and describe how they would incorporate learning opportunities, and then evaluate their progress. Practitioners, faculty members, and fourth-year PharmD students served as writing preceptors. Assessment. The success of the writing program was assessed by reviewing class performance and surveying writing preceptor’s opinions regarding the student’s achievement of program objectives. Class pass rates averaged greater than 99% over the 8 years of the program and the large majority of the writing preceptors reported that student learning objectives were met. A support pool of 99 writing preceptors was created. Conclusions. A 3-year reflective writing program improved pharmacy students’ reflection and reflective writing skills. PMID:23788811

    Patients with Marfan syndrome are referred for cardiac surgery due to root aneurysm with or without aortic valve regurgitation. Because these patients are young and frequently present with normal-appearing aortic cusps, valve sparing is often recommended. However, due to the genetic nature of the disease, the durability of such surgery remains uncertain. Between February 2004 and June 2012, 100 patients in our department suffering from aortic aneurysm with aortic valve regurgitation underwent elective aortic valve-sparing surgery. Of them, 30 had Marfan syndrome, were significantly younger (30 +/- 13 vs. 53 +/- 16 years), and had a higher percentage of root aneurysm, compared with ascending aorta aneurysm in their non-Marfan counterparts. We evaluated the safety, durability, clinical and echocardiographic mid-term results of these patients. While no early deaths were reported in either group, there were a few major early complications in both groups. At follow-up (reaching 8 years with a mean of 34 +/- 26 months) there were no late deaths, and few major late complications in the Marfan group. Altogether, 96% and 78% of the patients were in New York Heart Association functional class I-II in the Marfan and non-Marfan groups respectively. None of the Marfan patients needed reoperation on the aortic valve. Freedom from recurrent aortic valve regurgitation > 3+ was 94% in the Marfan patients. Aortic valve-sparing surgery in Marfan symdrome patients is safe and yields good mid-term clinical outcomes.

  3. Macula-Sparing rhegmatogenous retinal detachment: Is emergent surgery necessary?

    Full Text Available The status of the macula is a significant factor in determining final visual outcomes in rhegmatogenous retinal detachment (RRD and should be considered in the timing of surgical repair. Several studies have shown that macula-involving RRDs attain similar visual and anatomic outcomes when surgery is performed within seven days as compared to emergent surgery (within 24 hours. In contrast, surgery prior to macular detachment in macula-sparing RRDs generally yields the best visual outcomes. In the case of macula-sparing RRDs, it is not clear how long the macula may remain attached, therefore, standard practice dictates emergent surgery. Timing of presentation, examination findings, case complexity, co-existing medical conditions, surgeon expertise, and timing and quality of access to operating facilities and staff, however, should all be considered in determining whether a macula-sparing RRD requires immediate intervention or if equivalent visual and possibly better overall outcomes can be achieved with scheduled surgery within an appropriate time frame.

    This report provides perspectives gained by reviewing 75 Individual Plant Examination (IPE) submittals pertaining to 108 nuclear power plant units. IPEs are probabilistic analyses that estimate the core damage frequency (CDF) and containment performance for accidents initiated by internal events. The US Nuclear Regulatory Commission (NRC) reviewed the IPE submittals with the objective of gaining perspectives in three major areas: (1) improvements made to individual plants as a result of their IPEs and the collective results of the IPE program, (2) plant-specific design and operational features and modeling assumptions that significantly affect the estimates of CDF and containment performance, and (3) strengths and weaknesses of the models and methods used in the IPEs. These perspectives are gained by assessing the core damage and containment performance results, including overall CDF, accident sequences, dominant contributions to component failure and human error, and containment failure modes. Methods, data, boundary conditions, and assumptions used in the IPEs are considered in understanding the differences and similarities observed among the various types of plants. This report is divided into three volumes containing six parts. Part 1 is a summary report of the key perspectives gained in each of the areas identified above, with a discussion of the NRC's overall conclusions and observations. Part 2 discusses key perspectives regarding the impact of the IPE Program on reactor safety.

    2000-01-01

    In a previous paper, we have discussed the intelligent Windows 95-based data management program(IDPIN) which was developed for effective and efficient management of large amounts of pre-/in-service inspection(PSI/ISI) data of Kori nuclear power plants. The IDPIN program enables the prompt extraction of previously conducted PSI/ISI conditions and results so that the time-consuming data management, painstaking data processing and analysis of the past are avoided. In this study, the intelligent Windows based data management program(WS-IDPIN) has been developed as an effective data management of PSI/ISI data for the Wolsong nuclear power plants. The WS-IDPIN program includes the modules of comprehensive management and analysis of PSI/ISI results, statistical reliability assessment program of PSI/ISI results(depth and length sizing performance etc), standardization of UT report form and computerization of UT results. In addition, the program can be further developed as a unique PSI/ISI data management expert system which can be part of the PSI/ISI total support system for Korean nuclear power plants

  9. Simulation of an integrated age replacement and spare provisioning policy using SLAM

    International Nuclear Information System (INIS)

    Zohrul Kabir, A.B.M.; Farrash, S.H.A.

    1996-01-01

    This paper presents a SLAM simulation model for determining a jointly optimal age replacement and spare part provisioning policy. The policy, referred to as a stocking policy, is formulated by combining age replacement policy with a continuous review (s, S) type inventory policy, where s is the stock reorder level and S is the maximum stock level. The optimal values of the decision variables are obtained by minimizing the total cost of replacement and inventory. The simulation procedure outlined in the paper can be used to model any operating situation having either a single item or a number of identical items. Results from a number of case problems specifically constructed by 5-factor second order rotatory design have been presented and the effects of different cost elements, item failure characteristics and lead time characteristics have been highlighted. For all case problems, optimal (s, S) policies to support the Barlow-Proschan age policy have also been determined. Simulation results clearly indicate the separate optimizations of replacement and spare provisioning policies do not ensure global optimality when total system cost has to be minimized

  10. Tackling Fragmented Last Mile Deliveries to Nanostores by Utilizing Spare Transportation Capacity—A Simulation Study

    Directory of Open Access Journals (Sweden)

    Bram Kin

    2018-02-01

    Full Text Available Last mile deliveries in urban areas cause a disproportionate unsustainable impact, while it is also the most expensive part of the supply chain. This is particularly true for freight flows that are characterized by fragmentation. Logistically, this becomes apparent in vehicles that are driving around with a low vehicle fill rate, leading to the unnecessary presence of freight vehicles in our cities. This study focuses on the operational feasibility of utilizing the spare transportation capacity of a service-driven company as a potential solution to supply small independent retailers, or nanostores. The aim is to reduce inefficient vehicle movement. Based on a real-life implementation, we use SYnchronization Model for Belgian Inland Transport (SYMBIT, an agent-based model, to simulate various bundling scenarios. Results show the total vehicle kilometers and lead times to supply nanostores for the service-driven company to serve its customers. There is a potential to utilize spare capacity to supply nanostores while maintaining a decent service level. The number of vehicle kilometers driven highly depends on the location of the distribution center where the service-driven company operates. Based on these results, the conditions that have to be met to replicate this solution in other urban areas are discussed.

  11. Is the stripping technique a tissue-sparing procedure in large simple ovarian cysts in children?

    Stripping of the cystic wall is performed by gynecologists to treat large ovarian cysts. Information in the pediatric population is poor. We prospectively evaluated the pathologic specimens of large ovarian cyst to determine whether the stripping technique is a tissue-sparing procedure even in this age. We evaluated 5 patients. Samples were taken from the intermediate part of the cystic wall and from the layer covering the cyst during excision. The presence of ovarian tissue adjacent to the cyst wall, and the morphological features of the surrounding tissue were both evaluated. Pelvic ultrasound follow-up was also performed. Patients' mean age was 4.5 years (7 days to 12 years). All cysts were removed because all were symptomatic. The mean diameter was 86.6 mm (74-100 mm). Cysts were follicular in 2 cases, serous in other two, and endometriotic in 1 case. Adjacent ovarian tissue was present in 1 of 5 specimens and was approximately 1 to 2 mm in thickness. The layer adjacent to the cystic wall always appeared as normal ovarian tissue. Ultrasound scans at follow-up revealed presence of ovarian tissue. The stripping procedure for large ovarian cyst excision allows to spare the adjacent normal ovarian tissue even in pediatric age because ovarian tissue is rarely excised with the cyst wall during the procedure.

    We sought to examine the legal and ethical implications of workplace health risk reduction programs (HRRPs) using health risk assessments, individually focused risk reduction, and financial incentives to promote compliance. We conducted a literature review, analyzed relevant statutes and regulations, and considered the effects of these programs on employee health privacy. A variety of laws regulate HRRPs, and there is little evidence that employer-sponsored HRRPs violate these provisions; infringement on individual health privacy is more difficult to assess. Although current laws permit a wide range of employer health promotion activities, HRRPs also may entail largely unquantifiable costs to employee privacy and related interests.

    2018-04-01

    There is evidence that access to treatment for early stuttering is not available for all who need it. An internet version of the Lidcombe Program for early stuttering (Internet-LP) has been developed to deal with this shortfall. The LP is suitable for such development because it is delivered by parents in the child's everyday environment, with training by a speech-language pathologist. A Phase I trial of Internet-LP Part 1, comprising parent training, is reported here. Eight parents of pre-schoolers who stutter were recruited and six completed the trial. Post-trial assessment indicated that the parents scored well for identifying and measuring stuttering and for knowledge about conducting practice sessions, including how to present verbal contingencies during practice sessions. The results prompted minor adjustments to Part 1 and guided the construction of Part 2, which instructs parents during the remainder of the treatment process.

  17. National preceptor development program (PDP) prototype. The third of a 3-part series.

    2018-03-01

    Preceptor development is critical to successful delivery of experiential learning. Although many preceptor development programs exist, a more individualized approach to training is needed. To accomplish this a national preceptor development program should be considered based on the continuing professional development model. A detailed prototype for this program has been described. In this final installment of the series, the twelve evidence-based recommendations from the first installment were utilized to construct a prototype for a preceptor development program. Over a three-month period, investigators experimented with different designs and models before approving the final prototype. The prototype took the form of an electronic learning platform. Several categories were integral to the design and included sections entitled preceptor spotlight, mentorship, global outreach, choose your own adventure, continuing professional development, feedback, virtual online community, highlights/advertisements, what's new, competency assessment, and frequently asked questions. A graphic was developed to depict the process by which a preceptor would navigate through the web-based learning platform. The authors purposefully maintained a creative and unlimited vision for preceptor development. This conceptual model is intended to spark discussion and augment, refine, or develop entirely innovative ideas to meet preceptor needs. Development of a preceptor development platform could foster improved competency performance, enhanced interest in learning, and promote continuing professional development. With a greater focus on experiential education in pharmacy, the need for a national preceptor development resource is only expected to increase. Copyright © 2017 Elsevier Inc. All rights reserved.

  18. Program of Regional Collaboration between Eastern Part of Russia and Northeast China: Present and Future

    Full Text Available The author uses Russian and Chinese sources of information to analyze the current status and evaluate realization prospects of investment projects within the Cooperation Program between eastern regions of Russia and northeast China. State budget financed construction of transport and border infrastructure is being implemented as planned both in Russia and China. Sectoral distribution of key Program projects is found to be unbalanced: Russian regions specialize in mining and primary processing of natural resources while Chinese ones - in products with high share of added value. The study reveals that among 104 scheduled key Russian projects (at the cost of 47,9 billion USD only 24 projects are under implementation (11,77 billion USD, 8 of which are carried out with the help of Chinese investments (1,77 billion USD. Joint ventures are connected with mining operations, primary processing of wood, construction of houses, manufacturing of building materials, assembly production and trade. Among 111 scheduled Program Chinese projects (at the cost of 9,87 billion USD only 42 projects are under implementation (6,1 billion USD; they are associated with engineering products. There is only one Russian-Chinese joint venture on the territory of China (at the cost of 0,63 billion USD. The author suggests that in the near future 20 additional Program projects can be implemented in Russia (at the cost of more than 20 billion USD and 6 projects (about 0,5 billion USD - in China

    Wilson, Carol B; Brannan, Jane; White, Anne

    2010-12-01

    Mentorship has been identified as an influential factor in retaining new nursing faculty. A mentor-protégé program for novice faculty was implemented to promote development of the protégés in their role as nurse educators. A qualitative research study conducted to illuminate the meaning of experiences of mentors led to the emergence of four patterns: The Significance of the Mentor-Protégé Relationship, Communication as Important Between Mentor and Protégé, The Mentor-Protégé Program-Protégé's Perspectives, and The Mentoring Role as Expert Educator. The data from the study support the significance of providing mentorship to novice or new nurse educators. The data suggest that mentors benefit from participation in a mentor-protégé program as much as the protégés. Similar programs are needed in nursing if we are to mentor and encourage faculty to begin and remain in the role of educators to combat the future nurse educator shortage.

  15. High-Uranium-Loaded U3O8-Al fuel element development program. Part 1

    International Nuclear Information System (INIS)

    Martin, M.M.

    1993-01-01

    The High-Uranium-Loaded U 3 O 8 -Al Fuel Element Development Program supports Argonne National Laboratory efforts to develop high-uranium-density research and test reactor fuel to accommodate use of low-uranium enrichment. The goal is to fuel most research and test reactors with uranium of less than 20% enrichment for the purpose of lowering the potential for diversion of highly-enriched material for nonpeaceful usages. The specific objective of the program is to develop the technological and engineering data base for U 3 O 8 -Al plate-type fuel elements of maximal uranium content to the point of vendor qualification for full scale fabrication on a production basis. A program and management plan that details the organization, supporting objectives, schedule, and budget is in place and preparation for fuel and irradiation studies is under way. The current programming envisions a program of about four years duration for an estimated cost of about two million dollars. During the decades of the fifties and sixties, developments at Oak Ridge National Laboratory led to the use of U 3 O 8 -Al plate-type fuel elements in the High Flux Isotope Reactor, Oak Ridge Research Reactor, Puerto Rico Nuclear Center Reactor, and the High Flux Beam Reactor. Most of the developmental information however applies only up to a uranium concentration of about 55 wt % (about 35 vol % U 3 O 8 ). The technical issues that must be addressed to further increase the uranium loading beyond 55 wt % U involve plate fabrication phenomena of voids and dogboning, fuel behavior under long irradiation, and potential for the thermite reaction between U 3 O 8 and aluminum

    Busy scientists seek opportunities to implement education and outreach efforts, but often don't know where to start. One easy and tested method is to form collaborations with federally-funded adult education and adult literacy programs. These programs exist in every U.S. state and territory and serve underrepresented populations through such major initiatives as adult basic education, adult secondary education (and GED preparation), and English language acquisition. These students are workers, consumers, voters, parents, grandparents, and members of every community. They have specific needs that are often overlooked in outreach activities. This presentation will describe the steps by which the Oregon Ocean Science and Math Collaborative program was developed. It is based on a partnership between the Oregon Department of Community Colleges and Workforce Development, Oregon State University College of Oceanic and Atmospheric Sciences, Oregon Sea Grant, and the OSU Hatfield Marine Science Center. It includes professional development through instructor institutes; teachers at sea and informal education opportunities; curriculum and web site development. Through the partnership described here, instructors in adult basic education programs participate in a yearlong experience in which they develop, test, and adapt innovative instructional strategies to meet the specific needs of adult learners. This, in turn, leads to new prospects for study in the areas of ocean science and math and introduces non-academic careers in marine science to a new community. Working directly with instructors, we have identified expertise level, instructional environment, instructor background and current teaching strategies used to address science literacy and numeracy goals of the adult learners in the State of Oregon. Preliminary evaluation of our ongoing project in meeting these goals will be discussed. These efforts contribute to national goals of science literacy for all, by providing

    Priority #3 of the Canadian Experiential Education Project for Pharmacy provided evidence-based guidance for the design and implementation of a national approach to preceptor development. In this first article (of three), findings from the project and recommendations to achieve a high-quality preceptor development program (PDP) are presented. A multi-method approach including detailed semi-structured interviews, classic literature review, and advisory committee feedback was employed. The research team performed an integrated analysis of all data to achieve the objectives of Priority #3. Fifteen formal interviews, 167 articles and two stakeholder meetings informed findings. Experiential Education programs exhibited commonality in content and usually delivered programs online using modules or live lectures. Not all programs required preceptor education despite it being mandated by academic accreditors. Academics' perceptions varied regarding pharmacists' baseline knowledge, skills and attitudes prior to engaging in the preceptor role. A national approach to a PDP was desired if jurisdictional content was accommodated. Copious interprofessional literature of generally fair quality did not identify superior preceptor development approaches although there were numerous descriptions of interventions. Only 29 articles measured educational outcomes. Outcomes included satisfaction rates, self-efficacy and perceived knowledge, skill retention, skill implementation and participation rates. Twelve recommendations were identified to guide successful development of a national PDP. In the absence of good evidence, adult educational theory provided a basis for an effective PDP. Findings from Priority #3 may be relevant not only to pharmacy in Canada but other health professions and counterparts in other western nations with similar approaches to professional education.

    1996-05-01

    The theoretical background for the finite element computer program, MPSalsa, is presented in detail. MPSalsa is designed to solve laminar, low Mach number, two- or three-dimensional incompressible and variable density reacting fluid flows on massively parallel computers, using a Petrov-Galerkin finite element formulation. The code has the capability to solve coupled fluid flow, heat transport, multicomponent species transport, and finite-rate chemical reactions, and to solver coupled multiple Poisson or advection-diffusion- reaction equations. The program employs the CHEMKIN library to provide a rigorous treatment of multicomponent ideal gas kinetics and transport. Chemical reactions occurring in the gas phase and on surfaces are treated by calls to CHEMKIN and SURFACE CHEMKIN, respectively. The code employs unstructured meshes, using the EXODUS II finite element data base suite of programs for its input and output files. MPSalsa solves both transient and steady flows by using fully implicit time integration, an inexact Newton method and iterative solvers based on preconditioned Krylov methods as implemented in the Aztec solver library.

    Reeves, Anthony P.

    1986-01-01

    A number of algorithms were developed for image warping and pyramid image filtering. Techniques were investigated for the parallel processing of a large number of independent irregular shaped regions on the MPP. In addition some utilities for dealing with very long vectors and for sorting were developed. Documentation pages for the algorithms which are available for distribution are given. The performance of the MPP for a number of basic data manipulations was determined. From these results it is possible to predict the efficiency of the MPP for a number of algorithms and applications. The Parallel Pascal development system, which is a portable programming environment for the MPP, was improved and better documentation including a tutorial was written. This environment allows programs for the MPP to be developed on any conventional computer system; it consists of a set of system programs and a library of general purpose Parallel Pascal functions. The algorithms were tested on the MPP and a presentation on the development system was made to the MPP users group. The UNIX version of the Parallel Pascal System was distributed to a number of new sites.

  8. The potential of socio-psychological models for the development of prevention programs (Part 1

    Directory of Open Access Journals (Sweden)

    Bovina I.B.

    2014-12-01

    Full Text Available This paper considers the problem of designing prevention programs in health and disease. We note that smoking cessation on the planet would reduce mortality from various types of cancer by 25%, and would also save the lives of hundreds of thousands of people who die each year from heart attacks. Losing weight by only 10% through proper nutrition and exercise would reduce the incidence of cardiovascular disease, as well as certain types of cancer. Based on the literature review, we reveal the different types of prevention, show the importance of preventive measures aimed at the patient's immediate environment. Among the main difficulties associated with the development of effective prevention programs we discuss the following: 1 ignoring the psychological mechanisms of behavior change; 2 irrelevance of media broadcast methods in prevention campaigns; 3 the time between the problem behavior and its negative effects on health. We discuss the potential of social influence models for the development of prevention programs in the field of health and disease.

  10. Fractional Programming for Communication Systems—Part I: Power Control and Beamforming

    2018-05-01

    This two-part paper explores the use of FP in the design and optimization of communication systems. Part I of this paper focuses on FP theory and on solving continuous problems. The main theoretical contribution is a novel quadratic transform technique for tackling the multiple-ratio concave-convex FP problem--in contrast to conventional FP techniques that mostly can only deal with the single-ratio or the max-min-ratio case. Multiple-ratio FP problems are important for the optimization of communication networks, because system-level design often involves multiple signal-to-interference-plus-noise ratio terms. This paper considers the applications of FP to solving continuous problems in communication system design, particularly for power control, beamforming, and energy efficiency maximization. These application cases illustrate that the proposed quadratic transform can greatly facilitate the optimization involving ratios by recasting the original nonconvex problem as a sequence of convex problems. This FP-based problem reformulation gives rise to an efficient iterative optimization algorithm with provable convergence to a stationary point. The paper further demonstrates close connections between the proposed FP approach and other well-known algorithms in the literature, such as the fixed-point iteration and the weighted minimum mean-square-error beamforming. The optimization of discrete problems is discussed in Part II of this paper.

    As primary HPV screening programs are rolled out, methods are needed for routine quality assurance of HPV laboratory analyzes. To explore the use of similar design for audit as currently used in cytology-based screening, to estimate the clinical sensitivity to identify women at risk for CIN 3 or worse (CIN3+). Population-based cohort study conducted within the cervical screening program in Stockholm, Sweden, in 2011-2012. All women with histopathologically confirmed CIN3+ in the following two years were identified by registry analysis. Primary HPV and cytology screening results were collected. For women who had not been HPV tested, biobanked cytology samples were HPV-tested. If the original HPV result had been negative, the sample and subsequent biopsies were analyzed with broad HPV typing (general primer PCR and Luminex). 154 women had a biobanked prediagnostic cytology sample taken up to 2 years before a histopathologically confirmed CIN3+. The high-risk HPV-positivity was 97% (148/154 women), whereas 143/154 (94%) women had had a cytological abnormality. Among the six HPV-negative samples, one sample was HPV 33 positive in repeat testing whereas the other five cases were HPV-negative also on repeat testing, but HPV-positive in the subsequent tumor tissue. A sensitivity of the HPV test that is higher than the sensitivity of cytology suggests adequate quality of the testing. Regular audits of clinical sensitivity, similar to those of cytology-based screening, should be used also in HPV-based screening programs, in order to continuously monitor the performance of the analyzes.

    Erectile dysfunction has been widely investigated as the major factor responsible for sexual bother in patients after radical prostatectomy (RP); painful orgasm (PO) is one element of this bother, but little is known about its prevalence and its effects on sexual health. This study aims to investigate the prevalence of PO and to identify potential risk factors. A total of 1,411 consecutive patients underwent open (radical retropubic prostatectomy) or robot-assisted laparoscopic RP between 2002 and 2006. The patients were asked to complete a study-specific questionnaire. Of a total of 145 questions, 5 dealt with the orgasmic characteristics. The questionnaire was also administered to a comparison group of 442 persons, matched for age and area of residency. The response rate was 91% (1,288 patients). A total of 143 (11%) patients reported PO. Among the 834 men being able to have an orgasm, the prevalence was 18% vs. 6% in the comparison group (relative risk [RR] 2.8, 95% confidence interval [CI] 1.7-4.5). When analyzed as independent variables, bilateral seminal vesicle (SV)-sparing approach (RR 2.33, 95% CI 1.0-5.3, P = 0.045) and age <60 years were significantly related to the presence of PO (95% CI 0.5-0.9, P = 0.019). After adjustment for age, bilateral SV-sparing still remained a significant predictor for occurrence of PO. We found that PO occurs significantly more often in patients undergoing bilateral SV-sparing RP when compared with age-matched comparison population. © 2013 International Society for Sexual Medicine.

    Consumers' enrollment decisions in Medicare Part D can be explained by Abaluck and Gruber’s (2011) model of utility maximization with psychological biases or by a neoclassical version of their model that precludes such biases. We evaluate these competing hypotheses by applying nonparametric tests of utility maximization and model validation tests to administrative data. We find that 79 percent of enrollment decisions from 2006 to 2010 satisfied basic axioms of consumer theory under the assumption of full information. The validation tests provide evidence against widespread psychological biases. In particular, we find that precluding psychological biases improves the structural model's out-of-sample predictions for consumer behavior.

    In many cardiac units, aortic valve-sparing operations have become the preferred surgical procedure to treat aortic root aneurysm in patients with Marfan syndrome, based on relatively short-term outcomes. This study examined the long-term outcomes of aortic valve-sparing operations in patients with Marfan syndrome. All patients with Marfan syndrome operated on for aortic root aneurysm from 1988 through 2012 were followed prospectively for a median of 10 years. Follow-up was 100% complete. Time-to-event analyses were calculated using the Kaplan-Meier method with log-rank test for comparisons. A total of 146 patients with Marfan syndrome had aortic valve-sparing operations. Reimplantation of the aortic valve was performed in 121 and remodeling of the aortic root was performed in 25 patients. Mean age was 35.7 ± 11.4 years and two-thirds were men. Nine patients had acute, 2 had chronic type A, and 3 had chronic type B aortic dissections before surgery. There were 1 operative and 6 late deaths, 5 caused by complications of dissections. Mortality rate at 15 years was 6.8 ± 2.9%, higher than the general population matched for age and sex. Five patients required reoperation on the aortic valve: 2 for endocarditis and 3 for aortic insufficiency. Three patients developed severe, 4 moderate, and 3 mild-to-moderate aortic insufficiency. Rate of aortic insufficiency at 15 years was 7.9 ± 3.3%, lower after reimplantation than remodeling. Nine patients developed new distal aortic dissections during follow-up. Rate of dissection at 15 years was 16.5 ± 3.4%. Aortic valve-sparing operations in patients with Marfan syndrome were associated with low rates of valve-related complications in long-term follow-up. Residual and new aortic dissections were the leading cause of death. Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

    Full Text Available Background & Objective: Health family physician program is a complete system which eliminates the bewilderment of people and increases the satisfaction with health services as its most important results in medical care. The aim of this study was to evaluate the performance of family physicians and their strengths and weaknesses. Material & Methods: In this study, 52 family physicians were chosen via Random Stratified Sampling to participate in the study. A questionnaire titled “Performance of Family Physicians” with 5 domains of management, performance, contract guidelines, community involvement and results was used to collect data. Data were analyzed using SPSS-19 via t-test, ANOVA, Pearson correlation coefficient, and non-parametric tests. Results: Among the 52 studied family physicians, 56.9% were female and 43.1% were male. The lowest and the highest scores were obtained for the community involvement and results, respectively. Based on the results of this study, there were significant relationships among most of the domains. However, there was no significant correlation between the gender and different domains. Conclusion: In order to solve the problems of family physician program and improve the quality of services, more researches should be carried out soon to determine the types and causes of referring to the family physicians. Accordingly, appropriate interventions should be implemented to reduce the burden of visits and improve the quality of health services by guiding the society towards the prevention measures.

    Nitrogen fertilization of forest soils has been used for several decades to improve productivity. STORA plans to fertilize 10 to 15 thousand hectares forests with nitrogen annually, over an area of 1 545 000 hectares productive forest land. The ecological effects of this forest fertilization plan have been studied in the form of an environmental impact assessment (EIA). The first part of this EIA, presented in this report by the Swedish Environmental Research Institute (IVL), include the present and possible future state of the forest environment in Sweden, in relation to STORA owned forests and the fertilization programme and present knowledge about nitrogen cycling and forest fertilization. The second part, presented in a separate report contains information about the ecological effects of implementation of STORA fertilization plans, identification of shortcomings in knowledge to date, and recommendations for evasion of possible negative effects of implementation. Environmental effects of nitrogen fertilization are described in contrast to the possible environmental effects of acidification of soil and surface water, build-up of nitrogen pool in soils, leakage of nitrogen to surface waters from soils, changes in forest soil fertility, uptake and loss of climate affecting gases, and the biological diversity of the forest ecosystem. 193 refs, 4 figs, 7 tabs

    The Ecological Monitoring and Compliance program, funded through the U.S. Department of Energy, National Nuclear Security Administration Nevada Operations Office, monitors the ecosystem of the Nevada Test Site (NTS) and ensures compliance with laws and regulations pertaining to NTS biota. This report summarizes the program's activities conducted by Bechtel Nevada (BN) during fiscal year 2002. Program activities included: (1) biological surveys at proposed construction sites, (2) desert tortoise compliance, (3) ecosystem mapping and data management, (4) sensitive species and unique habitat monitoring, and (5) biological monitoring at the HAZMAT Spill Center. Biological surveys for the presence of sensitive species and important biological resources were conducted for 26 NTS projects. These projects have the potential to disturb a total of 374 acres. Thirteen of the projects were in desert tortoise habitat, and 13.38 acres of desert tortoise habitat were disturbed. No tortoises were found in or displaced from project areas, and no tortoises were accidentally injured or killed at project areas or along paved roads. Compilation of historical wildlife data continued this year in efforts to develop faunal distribution maps for the NTS. Photographs associated with the NTS ecological landform units sampled to create the NTS vegetation maps were cataloged for future retrieval and analysis. The list of sensitive plant species for which long-term population monitoring is scheduled was revised. Six vascular plants and five mosses were added to the list. Plant density estimates from ten populations of Astragalus beatleyae were collected, and eight known populations of Eriogonum concinnum were visited to assess plant and habitat status. Minimal field monitoring of western burrowing owl burrows occurred. A report relating to the ecology of the western burrowing owl on the Nevada Test Site was prepared which summarizes four years of data collected on this species

    This study aimed to determine the effects of a virtual reality exercise program using the Interactive Rehabilitation and Exercise System (IREX) on the recovery of motor and cognitive function and the performance of activities of daily living in stroke patients. [Subjects] The study enrolled 10 patients diagnosed with stroke who received occupational therapy at the Department of Rehabilitation Medicine of Hospital A between January and March 2014. [Methods] The patients took part in the virtual reality exercise program for 30 minutes each day, three times per week, for 4 weeks. Then, the patients were re-evaluated to determine changes in upper extremity function, cognitive function, and performance of activities of daily living 4 weeks after the baseline assessment. [Results] In the experimental group, there were significant differences in the Korea-Mini Mental Status Evaluation, Korean version of the modified Barthel index, and Fugl-Meyer assessment scores between the baseline and endpoint. [Conclusion] The virtual reality exercise program was effective for restoring function in stroke patients. Further studies should develop systematic protocols for rehabilitation training with a virtual reality exercise program.

    The summary report by Tom Weaver gives the overall background for the series of IVE (Integrated Verification Experiment) experiments including information on the full set of measurements made. This appendix presents details of the infrasound data for the and discusses certain aspects of a few special experiments. Prior to FY90, the emphasis of the Infrasound Program was on underground nuclear test (UGT) detection and yield estimation. During this time the Infrasound Program was a separate program at Los Alamos, and it was suggested to DOE/OAC that a regional infrasound network be established around NTS. The IVE experiments took place in a time frame that allowed simultaneous testing of possible network sites and examination of propagation in different directions. Whenever possible, infrasound stations were combined with seismic stations so that a large number could be efficiently fielded. The regional infrasound network was not pursued by DOE, as world events began to change the direction of verification toward non-proliferation. Starting in FY90 the infrasound activity became part of the Source Region Program which has a goal of understanding how energy is transported from the UGT to a variety of measurement locations.

    The Radiation Protection and Dosimetry Institute of the National Nuclear Energy Commission (IRD/CNEN) Brazilian and the Radiodiagnostic Service of the Rio de Janeiro Federal University Hospital, (Brazil), have been engaged in the development of quality control programs applied to radiodiagnostics, one of them concerning gastrointestinal fluoroscopy. Since fluoroscopic examinations normally deals with high doses, they represent an important fraction of public exposure. They deserve special attention and risks to patients should be considered individually, not only as a population statistics. This work describes steps followed and results obtained in the estimation of doses for patients and physicians. Examinations investigated were esofagography, gastroduodenal seriography and colon with double contrast media, using conventional equipment with fluorescent screens, carried on by physicians engaged in the first year of medical residence.

    Audits of the informed consent process are a key element of a clinical research quality assurance program. A systematic approach to such audits has not been described in the literature. In this paper we describe two components of the audit. The first is the audit of the informed consent document to verify adherence with federal regulations. The second component is comprised of the audit of the informed consent conference, with emphasis on a real time review of the appropriate communication of the key elements of the informed consent. Quality measures may include preparation of an informed consent history log, notes to accompany the informed consent, the use of an informed consent feedback tool, and the use of institutional surveys to assess comprehension of the informed consent process.

    The International Nuclear Model (INM) is a comprehensive model of the commercial nuclear power industry. It simulates economic decisions for reactor deployment and fuel management decisions based on an input set of technical, economic and scenario parameters. The technical parameters include reactor operating characteristics, fuel cycle timing and mass loss factors, and enrichment tails assays. Economic parameters include fuel cycle costs, financial data, and tax alternatives. INM has a broad range of scenario options covering, for example, process constraints, interregional activities, reprocessing, and fuel management selection. INM reports reactor deployment schedules, electricity generation, and fuel cycle requirements and costs. It also has specialized reports for extended burnup and permanent disposal. This volume contains appendices A through H including a description of subroutines and the Fortran listing of the program

    Level of repair analysis (LORA) is an important method of maintenance decision for establishing systems of operation and maintenance in the equipment development period. Currently, the research on equipment of repair level focuses on economic analy-sis models which are used to optimize costs and rarely considers the maintenance time required by the implementation of the main-tenance program. In fact, as to the system requiring high mission complete success, the maintenance time is an important factor which has a great influence on the availability of equipment sys-tems. Considering the relationship between the maintenance time and the spares stocks level, it is obvious that there are contra-dictions between the maintenance time and the cost. In order to balance these two factors, it is necessary to build an optimization LORA model. To this end, the maintenance time representing per-formance characteristic is introduced, and on the basis of spares stocks which is traditional y regarded as a decision variable, a de-cision variable of repair level is added, and a multi-echelon multi-indenture (MEMI) optimization LORA model is built which takes the best cost-effectiveness ratio as the criterion, the expected num-ber of backorder (EBO) as the objective function and the cost as the constraint. Besides, the paper designs a convex programming algorithm of multi-variable for the optimization model, provides solutions to the non-convex objective function and methods for improving the efficiency of the algorithm. The method provided in this paper is proved to be credible and effective according to the numerical example and the simulation result.

    The ecological effects of forest fertilization have been studied in the form of an environmental impact assessment (EIA). The first part of this EIA, presented in an earlier report by the Swedish Environmental Research Institute (IVL), included the present and possible future state of the forest environment in Sweden, in relation to STORA owned forests and the fertilization programme and present knowledge about nitrogen cycling and forest fertilization. The second part is presented here, and contains information about the ecological effects of implementation of STORA fertilization plans, identification of shortcomings in knowledge to date, and recommendations for evasion of possible negative effects of implementation. The general consensus of this EIA is that the forest fertilization plans drawn up by STORA will not negatively affect the use of the forest as a natural resource in an ecologically sound way, taken into account that the guidelines included in the EIA are followed. The possible environmental effects of a 10 to 20 year period from onset of the plan were studied in contrast to the possible environmental effects of acidification of soil and surface water, build-up of nitrogen pool in soils, leakage of nitrogen to surface waters from soils, changes in forest soil fertility, uptake and loss of climate affecting gases, and the biological diversity of the forest ecosystem. The recommendations given in this EIA include the choice of forest stands for fertilization, environmental awareness, amount of fertilizer applied, frequency of applications, application procedures and effects follow up, communications, and documentation of the events. 69 refs, 14 tabs

    Breast cancer radiotherapy represents an essential component in the overall management of both early stage and locally advanced breast cancer. As the number of breast cancer survivors has increased, chronic sequelae of breast cancer radiotherapy become more important. While recently published data suggest a potential for an increase in cardiac events with radiotherapy, these studies do not consider the impact of newer radiotherapy techniques commonly utilized. Therefore, the purpose of this review is to evaluate cardiac dose sparing techniques in breast cancer radiotherapy. Current options for cardiac protection/avoidance include (1) maneuvers that displace the heart from the field such as coordinating the breathing cycle or through prone patient positioning, (2) technological advances such as intensity modulated radiation therapy (IMRT) or proton beam therapy (PBT), and (3) techniques that treat a smaller volume around the lumpectomy cavity such as accelerated partial breast irradiation (APBI), or intraoperative radiotherapy (IORT). While these techniques have shown promise dosimetrically, limited data on late cardiac events exist due to the difficulties of long-term follow up. Future studies are required to validate the efficacy of cardiac dose sparing techniques and may use surrogates for cardiac events such as biomarkers or perfusion imaging

    Full Text Available The electrodeposition of chromium in programmed reversing current (RC, was investigated in the regime of high cathodic current density (77 A dm-2 and anodic current density (55 A dm-2. The ratio of the cathodic and anodic time (60 : 1 was used. Chromium was deposed on a steel substrate from a chromic-sulphuric acid solution, during one hour. Anode and cathode were suited in a system of parallel plates. Basic properties of deposits, like thickness, morphology, microhardness, brightness were examined. Surface distribution of the deposits was obtained from the measurements of the thicknesses of the deposits (between 32 and 67 µm. A ferromagnetic non-destructive method was used in the measurements. Based on the results, graphic models of deposit surface distribution were made. Two ranges of the thickness could be seen on the model (range 1 - average thickness 35.1 µm and range 2 - average thickness 57.81 µm. These results were statisticaly analysed by colums, rows and by the whole surface. For the whole specimens, the average thickness was 45.39 µm with a coefficient of variation of 0.2582. The basic properties of the deposits did not change with a variation of the thickness. Because of this, the coatings deposited with the reversing current could be much more considered reliable in wear and corrosion protection systems than ones deposited by direct current.

    Metal fabrication workers experience high rates of traumatic occupational injuries. Machine operators in particular face high risks, often stemming from the absence or improper use of machine safeguarding or the failure to implement lockout procedures. The National Machine Guarding Program (NMGP) was a translational research initiative implemented in conjunction with two workers' compensation insures. Insurance safety consultants trained in machine guarding used standardized checklists to conduct a baseline inspection of machine-related hazards in 221 business. Safeguards at the point of operation were missing or inadequate on 33% of machines. Safeguards for other mechanical hazards were missing on 28% of machines. Older machines were both widely used and less likely than newer machines to be properly guarded. Lockout/tagout procedures were posted at only 9% of machine workstations.

    For the last ten years, the Japanese High-Level Nuclear Waste (HLW) repository program has focused on assessing the feasibility of a basic repository concept, which resulted in the recently published H12 Report. As Japan enters the implementation phase, a new organization must identify, screen and choose potential repository sites. Thus, a rapid mechanism for determining the likelihood of site suitability is critical. The threshold approach, described here, is a simple mechanism for defining the likelihood that a site is suitable given estimates of several critical parameters. We rely on the results of a companion paper, which described a probabilistic performance assessment simulation of the HLW reference case in the H12 report. The most critical two or three input parameters are plotted against each other and treated as spatial variables. Geostatistics is used to interpret the spatial correlation, which in turn is used to simulate multiple realizations of the parameter value maps. By combining an array of realizations, we can look at the probability that a given site, as represented by estimates of this combination of parameters, would be good host for a repository site

    This quarterly progress report of the Aircraft Nuclear Propulsion Project at ORNL records the technical progress of the research on circulating-fuel reactors and other ANP research at the Laboratory under its Contract W-7405-eng-26. The report is divided into five major parts: 1. Aircraft Reactor Engineering, 2. Chemistry, 3. Metallurgy, 4. Heat Transfer and Physical Properties, Radiation Damage, and Fuel Recovery and Reprocessing, and 5. Reactor Shielding. The ANP Project is comprised of about 550 technical and scientific personnel engaged in many phases of research directed toward the achievement of nuclear propulsion of aircraft. A considerable portion of this research is performed in support of the work of other organizations participating in the national ANP effort. However, the bulk of the ANP research at ORNL is directed toward the development of a circulating-fuel type of reactor. The design, construction, and operation of the Aircraft Reactor Test (ART), with the cooperation of the Pratt & Whitney Aircraft Division, are the current objectives of the project. The ART is to be a power plant system that will include a 60-Mw circulating fuel reflector-moderator reactor and adequate means for heat disposal. Operation of the system will be for the purpose of determining feasibility and for studying the problems associated with the design, construction, and operation of a high-power circulating-fuel refIector-moderated aircraft reactor system.

    At the last RERTR meeting an historical overview was given and the status and consequences of enrichment reduction were discussed. At that time and somewhat more today many doubts are raised that enrichment reduction, as a tool for reducing the proliferation risk, is being done in the most efficient and convincing manner. The informations presented in this report were taken from IAEA, US-DOE, US-GAO publications and from proceedings of the RERTR meetings. The data presented should be compared only on a relative basis. It was not the intention for many reasons to present quantitative exact values as some figures used for developing the conclusions are being confidential. Others are available in the above mentioned publications and proceedings. But nevertheless conclusions drawn and recommendations developed are believed to be worth to be taken into account by research reactor operators, their funding organizations and administrators when they are faced with decisions about the future of their facilities. All of the international effort on reducing the enrichment on research and test reactors has their only justification from the INFCE (International Nuclear Fuel Cycle Evaluation) conclusions to reduce the proliferation risk worldwide to a large extent. Worldwide is important. IAEA and others have to convince operators and organizations upon the necessity in doing so. One of the best way convincing people is giving convincing examples. At present none of the nations having a military nuclear weapons program is giving such a convincing example. Even in cases where the qualified fuel and all other necessary tools for converting specific research reactors are existing only small or no progress can be seen. Only non-weapon states are being pressed today.

    Endometrial cancer recorded a peak incidence in ages 60-64 years in Romania, reaching in 2013 the average value of 8.06/ 100,000 women, and 15.97/ 100,000 women within the highest risk age range, having in recent years an increasing trend, being higher in urban than in rural population. Annually, approximately 800 new cases are registered in our country. The estimated lifetime risk of a woman to develop endometrial cancer is of about 1,03%. Based on an abnormal uterine bleeding, 35% of the endometrial cancers are diagnosed in an advanced stage of the disease, with significantly diminished lifetime expectancy. Drafting a national program for the early diagnosis of endometrial cancer. We proposed a standardization of the diagnostic steps and focused on 4 key elements for the early diagnosis of endometrial cancer: investigation of abnormal uterine bleeding occurring in pre/ post-menopausal women, investigating features/ anomalies of cervical cytology examination, diagnosis, treatment and proper monitoring of precursor endometrial lesions or cancer associated endometrial lesions and screening high risk populations (Lynch syndrome, Cowden syndrome). Improving medical practice based on diagnostic algorithms addresses the four risk groups, by improving information system reporting and record keeping. Improving addressability cases by increasing the health education of the population will increase the rate of diagnosis of endometrial cancer in the early stages of the disease.

    To use parts of the APhA Career Pathway Evaluation Program for Pharmacy Professionals in a career development laboratory designed to provide students with relevant information that will help them prepare for successful careers across the profession of pharmacy. Students enrolled in the second professional year of pharmacy school participated in an interactive three-hour career development laboratory. Students completed the APhA Career Pathway Evaluation Program for Pharmacy Professionals Online Assessment Tool prior to the laboratory. In class, the students were randomized into eight groups. Two career profiles were assigned to each group for discussion during a thirty-minute brainstorming session. The groups reported their knowledge for each career profile to the entire class, and the instructors supplemented the discussion with details and more specific information about each profile. Two years of data were collected (n=300 students). One hundred and twenty four (41.3%) students responded to the voluntary post-laboratory survey questions. Overall, students rated the career pathway activities favorably with an average score of 8.13 out of 10. After participation in the discussion, 74 (59.7%) respondents indicated their career interests had been impacted. This career development laboratory is one example of how the APhA Career Pathway Evaluation Program for Pharmacy Professionals can be effectively incorporated into the PharmD curriculum in order to help students explore the various career options they might not have otherwise discovered on their own.

    Full Text Available Introduction: The incidence of benign testicular tumors is increasing in particular in small lesion incidentally found at scrotal ultrasonography. Primary aim of this study was to perform radical surgery in malignant tumor. Secondary aim was to verify the efficacy of the diagnostic-therapeutic pathway recently adopted in management of small masses with testis sparing surgery in benign lesions. Materials and methods: In this multicenter study, we reviewed all patients with single testis lesion less than 15 mm at ultrasound as main diameter. We applied the diagnostic-therapeutic pathway described by Sbrollini et al. (Arch Ital Urol Androl 2014; 86:397 which comprises: 1 testicular tumor markers, 2 repeated scrotal ultrasound at the tertiary center, 3 surgical exploration with inguinal approach, intraoperative ultrasound, and intraoperative pathological examination. Definitive histology was reviewed by a dedicated uro-pathologist. Results: Twenty-eight patients completed this clinical flowchart. The mean lesion size was 9.3 mm (range 2.5-15. Testicular tumor markers were normal except in a case. Intraoperative ultrasound was necessary in 8/28 cases. We treated 11/28 (39.3% with immediate radical orchiectomy and 17/28 (60.7% with testis-sparing surgery. Definitive pathological results were: malignant tumor in 6 cases (seminoma, benign tumor in 10 cases (5 Leydig tumors, 2 Sertoli tumors, 1 epidermoid cyst, 1 adenomatoid tumor, 1 angiofibroma, benign disease in 11 (8 inflammation with haemorragic infiltration, 2 tubular atrophy, 1 fibrosis, and normal parenchyma in 1 case. We observed a good concordance between frozen section examination and definitive histology. Any malignant tumor was treated conservatively. Any delayed orchiectomy was necessary based on definitive histology. Conclusions: The incidence of benign lesions in 60% of small testis lesions with normal tumor markers makes orchiectomy an overtreatment. Testicular sparing surgery of single

    2017-01-01

    This book of knowledge (BoK) provides a critical review of the benefits and difficulties associated with using proton irradiation as a means of exploring the radiation hardness of commercial-off-the-shelf (COTS) systems. This work was developed for the NASA Electronic Parts and Packaging (NEPP) Board Level Testing for the COTS task. The fundamental findings of this BoK are the following. The board-level test method can reduce the worst case estimate for a board's single-event effect (SEE) sensitivity compared to the case of no test data, but only by a factor of ten. The estimated worst case rate of failure for untested boards is about 0.1 SEE/board-day. By employing the use of protons with energies near or above 200 MeV, this rate can be safely reduced to 0.01 SEE/board-day, with only those SEEs with deep charge collection mechanisms rising this high. For general SEEs, such as static random-access memory (SRAM) upsets, single-event transients (SETs), single-event gate ruptures (SEGRs), and similar cases where the relevant charge collection depth is less than 10 µm, the worst case rate for SEE is below 0.001 SEE/board-day. Note that these bounds assume that no SEEs are observed during testing. When SEEs are observed during testing, the board-level test method can establish a reliable event rate in some orbits, though all established rates will be at or above 0.001 SEE/board-day. The board-level test approach we explore has picked up support as a radiation hardness assurance technique over the last twenty years. The approach originally was used to provide a very limited verification of the suitability of low cost assemblies to be used in the very benign environment of the International Space Station (ISS), in limited reliability applications. Recently the method has been gaining popularity as a way to establish a minimum level of SEE performance of systems that require somewhat higher reliability performance than previous applications. This sort of application of

    In the present study the quality of reduction and incidence of complications in hip external rotator sparing modified posterior approach was assessed in both simple and complex acetabular fractures. This retrospective study includes 37 patients (38 hips) with a mean age of 42.1 years (range 21-60), that had been treated for displaced acetabular fractures from June 2007 through May 2011. They were reviewed at a mean of 3 years (20-67 months). The fractures were classified according to the Letournel-Judet classification. Anatomic reduction and stable fixation of the fracture with less than 2mm residual displacement was achieved in 28 of 38 hips. At the final follow up the patients were evaluated clinically according to Merle d'Aubigne and Postel scoring system which had been modified by Matta and radiologically based on the criteria described by Matta. The clinical results were excellent in 20, good in 8, fair in 8, and poor 2 hips. Complications included two superficial local wound infection and 10 heterotopic ossification with 7 of the cases having grade I heterotopic ossification. Avascular necrosis of the femoral head was not seen in any of the 38 hips. One patient with preoperative sciatic nerve palsy had complete recovery of neurologic function. There were no cases of deep vein thrombosis or pulmonary embolism. The functional outcome was satisfactory in most of the cases and comparable with other larger series. Using the limited part of Henry's sciatic nerve exposure skin incision - working in the plane between gluteus maximus and the tensor fascia lata as in the classical Gibson approach and two portal external rotator hip sparing approach resulted in good fracture reduction without approach related complications.

    The motivation to preserve sexual function can vary widely among patients before prostatectomy. Increasing patient involvement may allow a more personalized experience and may improve satisfaction. We assessed a strategy of surgeon deference to patient choice in regard to nerve sparing to determine to what degree patients are rational actors and capable of active decision making. A total of 150 patients treated with prostatectomy participated in a standardized preoperative discussion regarding the concept of nerve sparing, extracapsular extension and the potential need for adjuvant radiation in the event of local recurrence. Each patient was given his nomogram predicted risk of extracapsular extension and then elected nerve sparing or nonnerve sparing. The corresponding procedure was performed unless grossly invasive disease was encountered. Of the 150 patients 109 chose nerve sparing (73%) and 41 chose nonnerve sparing (27%). In patients with a nomogram predicted risk of extracapsular extension less than 20%, 20% to 50% and greater than 50%, nerve sparing was elected by 88%, 41% and 25%, respectively. Patients with lower risks of extracapsular extension electing nonnerve sparing were older and had higher rates of erectile dysfunction. Empowering patients to decide on their nerve sparing status is a reasonable strategy that did not lead to a high rate of patients with a high risk of extracapsular extension electing nerve sparing. With proper counseling informed patients made reasonable decisions, and appeared to be conservative, prioritizing cancer control in the majority of instances where extracapsular extension risk was high. In addition, they may have been overly conservative in electing nonnerve sparing when the risk was low. Copyright © 2011 American Urological Association Education and Research, Inc.

    Full Text Available This paper considers the problem of changing the value of selected characteristics for the operation of a two-level inventory system of maintainable parts depending on the flow of regenerated components in the inventory system. We analyzed the influence of the flow of regenerated components on the value of the coefficient of peripheral storage fill-rate, total costs and the average waiting time in the queue in peripheral warehouses, at different nominal values of the stocks in central and peripheral warehouses. The demand for spare parts in the peripheral warehouses is dependent on seasonal changes, modeled with an appopriate probability distribution. / В данной работе рассматривается проблема, касающаяся изменений стоимости закупок в работе двухуровневой системы снабжения запчастей, в зависимости от оборота запчастей в си- стеме снабжения.

    Radiation treatment techniques for whole-brain radiation therapy (WBRT) have not changed significantly since development of the procedure. However, the recent development of novel techniques such as intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT) and helical tomotherapy, as well as an increasing body of evidence concerning neural stem cells (NSCs) have altered the conventional WBRT treatment paradigm. In this regard, hippocampus-sparing WBRT is a novel technique that aims to spare critical hippocampus regions without compromising tumour control. Published data on this new technique are limited to planning and feasibility studies; data on patient outcome are still lacking. However, several prospective trials to analyse the feasibility of this technique and to document clinical outcome in terms of reduced neurotoxicity are ongoing. (orig.) [German] Die Technik der Ganzhirnbestrahlung (''whole-brain radiation therapy'', WBRT) hat sich seit der Entwicklung nicht wesentlich veraendert. Allerdings stellten die Neuentwicklung von Techniken wie die intensitaetsmodulierte Strahlentherapie (IMRT), die volumenmodulierte Arc-Therapie (VMAT) oder die helikale Tomotherapie sowie immer groesseres Wissen ueber das neurale Stammzellkompartiment (NSCs) das herkoemmliche Ganzhirn-Paradigma in Frage. Die hippocampusschonende Ganzhirnbestrahlung ist eine neuartige Technik, welche die kritische Region des Hippocampus schont, ohne die Tumorkontrolle zu gefaehrden. Ueber diese Technik gibt es bisher nur eine begrenzte Datenlage im Sinne von Planungs- und Machbarkeitsstudien. Klinische Daten bzgl. der Behandlungsergebnisse fehlen nach wie vor, aber einige prospektive Studien sind im Gange, um nicht nur die Machbarkeit zu belegen, sondern auch das klinische Outcome im Sinne einer verringerten Neurotoxizitaet nachzuweisen.

    To assess whether sparing neck-level IB in target delineation of node-positive (N+) oropharyngeal carcinoma (OPC) can improve xerostomia outcomes without compromising locoregional control (LRC). A total of 125 N+ OPC patients with a median age of 57 years underwent chemoradiation between May 2010 and December 2011. A total of 74% of patients had T1-T2 disease, 26% T3-T4, 16% N1, 8% N2A, 48% N2B, 28% N2C; 53% base of tongue, 41% tonsil, and 6% other. Patients were divided into those who had target delineation sparing of bilateral level IB (the spared cohort) versus no sparing (the treated cohort). Sparing of contralateral high-level II nodes was also performed more consistently in the spared cohort. A prospective xerostomia questionnaire (patient reported) was given at each patient follow-up visit to this cohort of patients to assess late xerostomia. Clinical assessment (observer rated) at each patient follow-up visit was also recorded. The 2-year LRC for the spared and treated cohorts was 97.5% and 93.8%, respectively (median follow-up, 23.2 mo). No locoregional failures occurred outside of treatment fields. The spared cohort experienced significant benefits in patient-reported xerostomia summary scores (P=0.021) and observer-rated xerostomia scores (P=0.006). In addition, there were significant reductions in mean doses to the ipsilateral submandibular gland (63.9 vs. 70.5 Gy; Pxerostomia outcomes.

    Rational planning of spares configuration project is an effective approach to improve equipment availability as well as reduce life cycle cost (LCC). With an analysis of various impacts on support system, the spares demand rate forecast model is constructed. According to systemic analysis method, spares support effectiveness evaluation indicators system is built, and then, initial spares configuration and optimization method is researched. To the issue of discarding and con-sumption for incomplete repairable items, its expected backorders function is approximated by Laplace demand distribution. Combining the (s-1, s) and (R, Q) inventory policy, the spares resup-ply model is established under the batch ordering policy based on inventory state, and the optimi-zation analysis flow for spares configuration is proposed. Through application on shipborne equipment spares configuration, the given scenarios are analyzed under two constraint targets:one is the support effectiveness, and the other is the spares cost. Analysis reveals that the result is consistent with practical regulation;therefore, the model’s correctness, method’s validity as well as optimization project’s rationality are proved to a certain extent.

    Delirium is associated with poor outcomes following acute hospitalization. A specialized delirium management unit, the Geriatric Monitoring Unit (GMU), was established. Evening bright light therapy (2000-3000 lux; 6-10 pm daily) was added as adjunctive treatment, to consolidate circadian activity rhythms and improve sleep. This study examined whether the GMU program improved sleep, cognitive, and functional outcomes in delirious patients. A total of 228 patients (mean age = 84.2 years) were studied. The clinical characteristics, delirium duration, delirium subtype, Delirium Rating Score (DRS), cognitive status (Chinese Mini-Mental State Examination), functional status (modified Barthel Index [MBI]), and chemical restraint use during the initial and predischarge phase of the patient's GMU admission were obtained. Nurses completed hourly 24-hour patient sleep logs, and from these, the mean total sleep time, number of awakenings, and sleep bouts (SB) were computed. The mean delirium duration was 6.7 ± 4.6 days. Analysis of the delirium subtypes showed that 18.4% had hypoactive delirium, 30.2% mixed delirium, and 51.3% had hyperactive delirium. There were significant improvements in MBI scores, especially for the hyperactive and mixed delirium subtypes (P hours) (P hours) (P bright light therapy as part of a multicomponent delirium management program. The benefits appear to have occurred mainly in patients with hyperactive delirium, which merits further in-depth, randomized controlled studies.

    The aim of this study was to describe the didactic and clinical undergraduate implant dentistry program of the Albert-Ludwigs University, Freiburg, Germany, with emphasis on the clinical implant experience. A detailed description of the implant curriculum at Albert-Ludwigs University is given with documented exemplary cases and additional flow charts. All students participate in 28 hours of lectures and approximately 64 hours of seminars with hands-on courses and gain clinical experience. All undergraduate students are eligible to place and restore oral implants. Emphasis is placed on prosthetic-driven planning of implant positions, three-dimensional imaging, and computer-guided implant placement. Implant restorations performed by undergraduate students comprise single crowns and small multiunit fixed dental prostheses in partially edentulous posterior maxillae and anterior or posterior mandibles, implant-retained overdentures (snap attachment) in edentulous patients, and telescopic fixed-removable dental prostheses on remaining teeth and strategically placed additional implants. Over the past 2.5 years, 51 patients were treated with 97 dental implants placed by students in the undergraduate program. Seventy-one restorations were inserted: 60.6% single crowns, 7% fixed dental protheses, 21.1% overdentures, and 11.3% telescopic fixed-removable dental prostheses. The implant survival rate was 98.9%. Because survival rates for dental implants placed and restored by students are comparable to those of experienced dentists, oral implant dentistry should be implemented as part of the undergraduate dental curriculum.

  16. SOME SIMPLE APPROACHES TO PLANNING THE INVENTORY OF SPARE COMPONENTS OF AN INDUSTRIAL SYSTEM

    Directory of Open Access Journals (Sweden)

    Alenka Brezavšek

    2016-02-01

    Full Text Available Two variants of a simple stochastic model for planning the inventory of spare components supporting maintenance of an industrial system are developed. In both variants, the aim is to determine how many spare components are needed at the beginning of a planning interval to fulfil demand for corrective replacements during this interval. Under the first variant, the acceptable probability of spare shortage during the planning interval is chosen as a decision variable while in the second variant, the adequate spare inventory level is assessed taking into account the expected number of component failures within the planning interval. Calculation of the number of spare components needed depends on the form of the probability density function of component failure times. Different statistical density functions that are useful to describe this function are presented. Advantages and disadvantages of using a particular density function in our model are discussed. The applicability of the model is given through illustrative numerical examples.

    The Lake Roosevelt Fisheries Evaluation Program is the result of a merger between two projects, the Lake Roosevelt Monitoring Program (BPA No. 8806300) and the Lake Roosevelt Data Collection Project (BPA No. 9404300). These projects were merged in 1996 to continue work historically completed under the separate projects, and is now referred to as the Lake Roosevelt Fisheries Evaluation Program. The 1998 Annual Report, Part B. Limnology, Primary Production, and Zooplankton in Lake Roosevelt, Washington examined the limnology, primary production, and zooplankton at eleven locations throughout the reservoir. The 1998 research protocol required a continuation of the more complete examination of limnological parameters in Lake Roosevelt that began in 1997. Phytoplankton and periphyton speciation, phytoplankton and periphyton chlorophyll a analysis, complete zooplankton biomass analysis by taxonomic group, and an increased number of limnologic parameters (TDG, TDS, etc.) were examined and compared with 1997 results. Total dissolved gas levels were greatly reduced in 1998, compared with 1997, likely resulting from the relatively normal water year experienced in 1998. Mean water temperatures were similar to what was observed in past years, with a maximum of 22.7 C and a minimum of 2.6 C. Oxygen concentrations were also relatively normal, with a maximum of 16.6 mg/L, and a minimum of 0.9 mg/L. Phytoplankton in Lake Roosevelt was primarily composed of microplankton (29.6%), Cryptophyceae (21.7%), and Bacillriophyceae (17.0 %). Mean total phytoplankton chlorophyll a maximum concentration occurred in May (3.53 mg/m{sup 3}), and the minimum in January (0.39 mg/m{sup 3}). Phytoplankton chlorophyll a concentrations appear to be influenced by hydro-operations and temperature. Trophic status as indicated by phytoplankton chlorophyll a concentrations place Lake Roosevelt in the oligomesotrophic range. Periphyton colonization rates and biovolume were significantly greater at a depth

    To demonstrate the feasibility and accessibility of performing adequate mastectomy to extirpate the breast tissue, along with en-block formal axillary dissection performed from within the same incision. We also compared different methods of immediate breast reconstruction used to fill the skin envelope to achieve the best aesthetic results. Methods: 38 patients with breast cancer underwent skin-sparing mastectomy with formal axillary clearance, through a circum-areolar incision. Immediate breast reconstruction was performed using different techniques to fill in the skin envelope. Two reconstruction groups were assigned; group 1: Autologus tissue transfer only (n= 24), and group 2: implant augmentation (n= 14). Autologus tissue transfer: The techniques used included filling in the skin envelope using Extended Latissimus Dorsi flap (18 patients) and Pedicled TRAM flap (6 patients). Augmentation with implants: Subpectoral implants(4 patients), a rounded implant placed under the pectoralis major muscle to augment an LD reconstructed breast. LD pocket (10 patients), an anatomical implant placed over the pectoralis major muscle within a pocket created by the LD flap. No contra-lateral procedure was performed in any of the cases to achieve symmetry. Results: All cases underwent adequate excision of the breast tissue along with en-block complete axillary clearance (when indicated), without the need for an additional axillary incision. Eighteen patients underwent reconstruction using extended LD flaps only, six had TRAM flaps, four had augmentation using implants placed below the pectoralis muscle along with LD flaps, and ten had implants placed within the LD pocket. Breast shape, volume and contour were successfully restored in all patients. Adequate degree of ptosis was achieved, to ensure maximal symmetry. Conclusions: Skin Sparing mastectomy through a circum-areolar incision has proven to be a safe and feasible option for the management of breast cancer in Egyptian

    Purpose: In left-sided tangential breast intensity modulated radiation therapy (IMRT), the heart may enter the radiation field and receive excessive radiation while the patient is breathing. The patient’s breathing pattern is often irregular and unpredictable. We verify the clinical applicability of a heart-sparing robust optimization approach for breast IMRT. We compare robust optimized plans with clinical plans at free-breathing and clinical plans at deep inspiration breath-hold (DIBH) using active breathing control (ABC). Methods: Eight patients were included in the study with each patient simulated using 4D-CT. The 4D-CT image acquisition generated ten breathing phase datasets. An average scan was constructed using all the phase datasets. Two of the eight patients were also imaged at breath-hold using ABC. The 4D-CT datasets were used to calculate the accumulated dose for robust optimized and clinical plans based on deformable registration. We generated a set of simulated breathing probability mass functions, which represent the fraction of time patients spend in different breathing phases. The robust optimization method was applied to each patient using a set of dose-influence matrices extracted from the 4D-CT data and a model of the breathing motion uncertainty. The goal of the optimization models was to minimize the dose to the heart while ensuring dose constraints on the target were achieved under breathing motion uncertainty. Results: Robust optimized plans were improved or equivalent to the clinical plans in terms of heart sparing for all patients studied. The robust method reduced the accumulated heart dose (D10cc) by up to 801 cGy compared to the clinical method while also improving the coverage of the accumulated whole breast target volume. On average, the robust method reduced the heart dose (D10cc) by 364 cGy and improved the optBreast dose (D99%) by 477 cGy. In addition, the robust method had smaller deviations from the planned dose to the

    Pre-operative scalp shaving is conventionally thought to simplify postoperative cranial wound care, lower the rate of wound infections, and ease optimal incision localization. Over the past few decades, some neurosurgeons have refrained from scalp shaving in order to improve patient satisfaction with brain surgery. However, this hair-sparing approach has not yet been explored in the growing field of magnetic resonance-guided laser interstitial thermal therapy (MRgLITT). This study investigated the initial impact of a no-shave technique on post-operative wound infection rate as well as on entry and target accuracy in MRgLITT for mesial temporal epilepsy. Eighteen patients selected by the Stanford Comprehensive Epilepsy Program between November 2015 and August 2017 were included in the study. All patients underwent functional selective amygdalohippocampotomies using MRgLITT entirely within a diagnostic MRI suite. No hair was removed and no additional precautions were taken for hair or scalp care. Otherwise, routine protocols for surgical preparations and wound closure were followed. The study was performed under approval from Stanford University's Internal Review Board (IRB-37830). No post-operative wound infections or erosions occurred for any patient. The mean entry point error was 2.87 ± 1.3 mm and the mean target error was 1.0 ± 0.9 mm. There have been no other complications associated with this hair-sparing approach. The study's results suggest that hair sparing in MRgLITT surgery for temporal epilepsy does not increase the risk of wound complications or compromise accuracy. This preferred cosmetic approach may thus appeal to epilepsy patients considering such interventions. Copyright © 2018 Elsevier Ltd. All rights reserved.

    In this paper we address two topical questions: How do the quality of governance and agricultural intensification impact on spatial expansion of agriculture? Which aspects of governance are more likely to ensure that agricultural intensification allows sparing land for nature? Using data from the Food and Agriculture Organization, the World Bank, the World Database on Protected Areas, and the Yale Center for Environmental Law and Policy, we estimate a panel data model for six South American countries and quantify the effects of major determinants of agricultural land expansion, including various dimensions of governance, over the period 1970–2006. The results indicate that the effect of agricultural intensification on agricultural expansion is conditional on the quality and type of governance. When considering conventional aspects of governance, agricultural intensification leads to an expansion of agricultural area when governance scores are high. When looking specifically at environmental aspects of governance, intensification leads to a spatial contraction of agriculture when governance scores are high, signaling a sustainable intensification process.

  13. Memory sparing, fast scattering formalism for rigorous diffraction modeling

    Iff, W.; Kämpfe, T.; Jourlin, Y.; Tishchenko, A. V.

    2017-07-01

    The basics and algorithmic steps of a novel scattering formalism suited for memory sparing and fast electromagnetic calculations are presented. The formalism, called ‘S-vector algorithm’ (by analogy with the known scattering-matrix algorithm), allows the calculation of the collective scattering spectra of individual layered micro-structured scattering objects. A rigorous method of linear complexity is applied to model the scattering at individual layers; here the generalized source method (GSM) resorting to Fourier harmonics as basis functions is used as one possible method of linear complexity. The concatenation of the individual scattering events can be achieved sequentially or in parallel, both having pros and cons. The present development will largely concentrate on a consecutive approach based on the multiple reflection series. The latter will be reformulated into an implicit formalism which will be associated with an iterative solver, resulting in improved convergence. The examples will first refer to 1D grating diffraction for the sake of simplicity and intelligibility, with a final 2D application example.

    The nuclear industry continues to be faced with increasing external pressures that contribute to escalating production costs. In the past, regulatory and political pressures have been the chief sources for the authors concern. Today, however, the economic aspects for power generation may present an equal or an even greater challenge to the industry's stability. For nuclear utilities to survive and prosper, they must become more cost conscious and competitive. This challenge becomes even more important when one considers the growing number of cogeneration facilities, new independent power producers, and neighboring utilities all competing for the customer on a cost basis. This paper addresses opportunities created by the development of recent industry guidelines addressing engineering analysis techniques to be used during replenishment of system spares and components. This activity, while it has not been traditionally thought of as an engineering activity, can contribute significantly to the reduction of operation and maintenance (O and M) costs for plant systems and will help nuclear utilities to aggressively battle the rising issue of cost control

  15. Valve-sparing aortic root replacement in Marfan syndrome.

    2005-01-01

    Marfan syndrome is the most common inherited connective tissue disorder, affecting approximately 1 in 10,000 live births. The cardinal features of Marfan syndrome are the abnormalities of the skeleton (tall stature, arachnodactyly, and joint hyperelasticity), eye (lens subluxation), and aorta (root aneurysm with proclivity toward rupture and dissection). Aortic catastrophe accounts for most of the premature mortality among Marfan patients, a risk that climbs steeply during adolescence and results in death of half of Marfan patients by the age of 40 years. Most of the improvement in life expectancy that has been achieved in Marfan syndrome is attributable to early recognition of aortic root aneurysms and prophylactic replacement with composite grafts (mechanical valve prostheses within Dacron conduits) before rupture or dissection occurs. Despite the excellent early and late results with composite grafts, there has been growing interest in operative procedures that replace the sinuses but preserve the aortic valve leaflets, to avoid anticoagulation and minimize the risk of prosthesis-related endocarditis. These procedures are still in evolution and late results are not yet known, but as with mitral repair in the setting of myxomatous disease, valve-sparing procedures in Marfan syndrome have weathered a storm of initial criticism and skepticism and are steadily gaining acceptance.

    Aortic valve sparing root surgery (AVSRS) is a safe and durable alternative for patients with dilated roots or pure aortic regurgitation (AR), which avoids the risks of anticoagulation or valvular degeneration with prosthetic valves. Notwithstanding the theoretical challenges of greater tissue fragility in Marfan syndrome (MFS), AVSRS has been demonstrated to have equal outcomes in this condition as it does in those without MFS. The benefits of retaining the native aortic valve in this generally younger age group extend beyond those of avoiding the inconvenience and complications of prolonged exposure to anticoagulants and include ease of management for future aortic, cardiac and non-cardiac procedures which are the norm for these patients. The essential principles of AVSRS in MFS do not differ from those for the rest of the population. Successful repair and durable valve function depend on a sound understanding of the close interaction between the structure and function of this exquisitely designed piece of engineering. We are fortunate to have numerous tools in our surgical armamentarium to preserve these valves. It is the purpose of this paper to demystify the complex structure-function interactions of the aortic valve, thereby gaining an intuition for AVSRS. We will also elaborate on specific technical details of established techniques that we have found successful in preserving the normal function of these valves in the long term.

    The shutdown of Trillo NPP due to an irreparable in situ fault in the stator of the electric generator, has resulted in the need to transport a spare stator from Mulheim (Germany) to Trillo I NPP (Spain). The problem occasioned by this type of transport have been exacerbated by the very short period of time available to plan and carry out this operation. Owing to this pressing need, the logistics of the transport were tackled from all possible alternative approaches. Within each one of these alternatives, all available modes were considered, so as to minimise the possibility of an insurmountable difficulty arising and thus making it impossible to continue with trans transportation. The two basic alternatives considered were road and rail. This paper describes the different aspects which intervened in this special transport, especially the following: - The very short time period available for planning and execution - The railway transport mode used - The large number of organisations participating in the operation - The solution to the technical problems caused by the use of different types of transportation equipment - The studies, adaptations and improvements carried out on the different routes - The coordination of the resources used in the operation.

    Ovarian transposition is a highly effective surgical procedure used to preserve ovarian function in premenopausal patients with cancers requiring postoperative or primary pelvic radiotherapy. Pelvic irradiation determines severe damage of ovarian DNA and iatrogenic ovarian failure with premature menopause, necessity of long-term hormone replacement therapy and infertility. We conducted an extensive research of the literature in Medline between January 2000 and April 2015 using the key-words "ovarian transposition radiotherapy", "radiotherapy gonadal function", radiotherapy fertility sparing". The population included young women with normal ovarian function affected by cancers that required pelvic radiotherapy. We have examined 32 articles reporting on 1189 women undergoing ovarian transposition. Median age was 32.5 years, follow up was median 48 months. The procedure has been performed in patients less than 40 years of age. Surgery has been achieved by laparotomy or laparoscoy. We have analyzed effects of radiotherapy on ovarian function. The proportion of women treated by ovarian transposition preserved ovarian function was 70%. About 86% of patients did not develop ovarian cysts and in 98-99% of cases did not occur any metastatic disease. Ovarian transposition is associated with significant preservation of ovarian function and a low frequency of complications as cysts and metastasis. In 31% of cases the procedure can fail. Further studies are needed to evaluate the efficacy of ovarian transposition and the follow up. Ovarian transposition should be discussed at the time of cancer diagnosis in every premenopausal woman requiring pelvic radiotherapy.

    In rats receiving total parenteral nutrition with or without sodium 2-ketoisocaproate (KIC; 2.48 g.kg-1.day-1), L-[1- 13 C]leucine and [1- 14 C]KIC were constantly infused for 6 h. CO 2 production, 14 CO 2 production, 13 CO 2 enrichment, urinary urea nitrogen (N) plus ammonia N and total urinary N were measured. Whole body protein synthesis (S) was calculated in non-KIC-infused rats and also in unfed rats infused with [1- 14 C]leucine from fractional oxidation of labeled leucine (1-F), where F is fractional utilization for protein synthesis, and urea N plus ammonia N excretion (C) as S = C x F/(1-F). Addition of KIC caused a significant reduction in N excretion and a significant improvement in N balance. Fractional oxidation of labeled KIC increased, whereas fractional utilization of labeled KIC for protein synthesis decreased, but the extent of incorporation of infused KIC into newly synthesized protein (as leucine) amounted to at least 40% of the total rate of leucine incorporation into newly synthesized whole body protein. We conclude that addition of KIC spares N in parenterally fed rats and becomes a major source of leucine for protein synthesis

    In this paper we address two topical questions: How do the quality of governance and agricultural intensification impact on spatial expansion of agriculture? Which aspects of governance are more likely to ensure that agricultural intensification allows sparing land for nature? Using data from the Food and Agriculture Organization, the World Bank, the World Database on Protected Areas, and the Yale Center for Environmental Law and Policy, we estimate a panel data model for six South American countries and quantify the effects of major determinants of agricultural land expansion, including various dimensions of governance, over the period 1970-2006. The results indicate that the effect of agricultural intensification on agricultural expansion is conditional on the quality and type of governance. When considering conventional aspects of governance, agricultural intensification leads to an expansion of agricultural area when governance scores are high. When looking specifically at environmental aspects of governance, intensification leads to a spatial contraction of agriculture when governance scores are high, signaling a sustainable intensification process.

    Long-term chronic alcoholism is associated with disparate and widespread residual consequences for brain functioning and behavior, and alcoholics suffer a variety of cognitive deficiencies and emotional abnormalities. Alcoholism has heterogeneous origins and outcomes, depending upon factors such as family history, age, gender, and mental or physical health. Consequently, the neuropsychologic profiles associated with alcoholism are not uniform among individuals. Moreover, within and across research studies, variability among subjects is substantial and contributes to characteristics associated with differential treatment outcomes after detoxification. In order to refine our understanding of alcoholism-related impaired, spared, and recovered abilities, we focus on five specific functional domains: (1) memory; (2) executive functions; (3) emotion and psychosocial skills; (4) visuospatial cognition; and (5) psychomotor abilities. Although the entire brain might be vulnerable in uncomplicated alcoholism, the brain systems that are considered to be most at risk are the frontocerebellar and mesocorticolimbic circuitries. Over time, with abstinence from alcohol, the brain appears to become reorganized to provide compensation for structural and behavioral deficits. By relying on a combination of clinical and scientific approaches, future research will help to refine the compensatory roles of healthy brain systems, the degree to which abstinence and treatment facilitate the reversal of brain atrophy and dysfunction, and the importance of individual differences to outcome. © 2014 Elsevier B.V.

    To describe adaptive optics (AO) imaging of foveal sparing in geographic atrophy (GA) secondary to age-related macular degeneration. Flood-illumination AO infrared (IR) fundus images were obtained in four consecutive patients with GA using an AO retinal camera (rtx1; Imagine Eyes). Adaptive optics IR images were overlaid with confocal scanning laser ophthalmoscope near-IR autofluorescence images to allow direct correlation of en face AO features with areas of foveal sparing. Adaptive optics appearance of GA and foveal sparing, preservation of functional photoreceptors, and cone densities in areas of foveal sparing were investigated. In 5 eyes of 4 patients (all female; mean age 74.2 ± 11.9 years), a total of 5 images, sized 4° × 4°, of foveal sparing visualized on confocal scanning laser ophthalmoscope near-IR autofluorescence were investigated by AO imaging. En face AO images revealed GA as regions of inhomogeneous hyperreflectivity with irregularly dispersed hyporeflective clumps. By direct comparison with adjacent regions of GA, foveal sparing appeared as well-demarcated areas of reduced reflectivity with less hyporeflective clumps (mean 14.2 vs. 3.2; P = 0.03). Of note, in these areas, en face AO IR images revealed cone photoreceptors as hyperreflective dots over the background reflectivity (mean cone density 3,271 ± 1,109 cones per square millimeter). Microperimetry demonstrated residual function in areas of foveal sparing detected by confocal scanning laser ophthalmoscope near-IR autofluorescence. Adaptive optics allows the appreciation of differences in reflectivity between regions of GA and foveal sparing. Preservation of functional cone photoreceptors was demonstrated on en face AO IR images in areas of foveal sparing detected by confocal scanning laser ophthalmoscope near-IR autofluorescence.

    Full Text Available This article is a presentation of “Mathematical and Physical Basics in Informatics” Module projected as part of universal baccalaureate model realized in Minin State Pedagogical University, Nizhny Novgorod, within the educational program for an extended group of qualifications “Informatics and Calculating Machines”. Module authors defined a strategy for baccalaureates preparation in the field of informational technology, which is realized due to a bunch of principles: education fundamentalization, learning systematization, activity, integration and student-centration. The principle of education fundamentalization requires consolidation of scientific and methodological preparation of students. The principle of learning systematization guarantees formation of students’ holistic ideology. The principle of integration is directed onto qualitative interdisciplinary conversion based on mutual enrichment of knowledge and skills. The principle of activity considers student personality, its formation and growth with respect to practical activity as a special form of psychical activity. The principle of student-centration is displayed as social-humanistic purpose of the educational process.

  6. Diaphragm-Sparing Nerve Blocks for Shoulder Surgery.

    Tran, De Q H; Elgueta, Maria Francisca; Aliste, Julian; Finlayson, Roderick J

    Shoulder surgery can result in significant postoperative pain. Interscalene brachial plexus blocks (ISBs) constitute the current criterion standard for analgesia but may be contraindicated in patients with pulmonary pathology due to the inherent risk of phrenic nerve block and symptomatic hemidiaphragmatic paralysis. Although ultrasound-guided ISB with small volumes (5 mL), dilute local anesthetic (LA) concentrations, and LA injection 4 mm lateral to the brachial plexus have been shown to reduce the risk of phrenic nerve block, no single intervention can decrease its incidence below 20%. Ultrasound-guided supraclavicular blocks with LA injection posterolateral to the brachial plexus may anesthetize the shoulder without incidental diaphragmatic dysfunction, but further confirmatory trials are required. Ultrasound-guided C7 root blocks also seem to offer an attractive, diaphragm-sparing alternative to ISB. However, additional large-scale studies are needed to confirm their efficacy and to quantify the risk of periforaminal vascular breach. Combined axillary-suprascapular nerve blocks may provide adequate postoperative analgesia for minor shoulder surgery but do not compare favorably to ISB for major surgical procedures. One intriguing solution lies in the combined use of infraclavicular brachial plexus blocks and suprascapular nerve blocks. Theoretically, the infraclavicular approach targets the posterior and lateral cords, thus anesthetizing the axillary nerve (which supplies the anterior and posterior shoulder joint), as well as the subscapular and lateral pectoral nerves (both of which supply the anterior shoulder joint), whereas the suprascapular nerve block anesthetizes the posterior shoulder. Future randomized trials are required to validate the efficacy of combined infraclavicular-suprascapular blocks for shoulder surgery.

    To demonstrate surgical techniques utilized during uterine-sparing laparoscopic resections of accessory cavitated uterine masses (ACUMs). ACUMs represent a rare uterine entity observed in premenopausal women suffering from dysmenorrhea and recurrent pelvic pain. The diagnosis is made when an isolated extra-cavitated uterine mass is resected from an otherwise normal appearing uterus with unremarkable endometrial lumen and adnexal structures. Pathologic confirmation requires an accessory cavity lined with endometrial epithelium (and corresponding glands and stroma) filled with chocolate-brown fluid. Adenomyosis must be absent. Although the origin of ACUMs is currently unknown, the most common presentation is a 2-4 cm lateral uterine wall mass at the level of the insertion of the round ligament. Hence it has been hypothesized that gubernaculum dysfunction may be responsible for duplication or persistence of paramesonephric tissue leading to ACUM formation as a new Müllerian anomaly. A stepwise surgical tutorial describing 2 laparoscopic ACUM resections using a narrated video (Canadian Task Force classification III). An academic tertiary care hospital. In this video, we present 2 patients who underwent uterine-sparing laparoscopic resections of their ACUM in order to preserve fertility (Case 1) or avoid the complications and surgical recovery time of a total laparoscopic hysterectomy (Case 2). Case 1 is a 19-year-old, gravida 0, para 0 woman with dysmenorrhea and recurrent pelvic pain who presented for multiple emergency room and outpatient evaluations. Transvaginal ultrasonography was unremarkable except for a 28×30×26mm left lateral uterine mass with peripheral vascular flow that was initially felt to be a leiomyoma or rudimentary uterine horn. MRI imaging, however, demonstrated this mass to be more consistent with an ACUM. This was based on the lack of communication between the lesion and the main uterine cavity exhibited by high T2 signal (compatible with

    This exploratory study aims at making a status of the present day situation of the foreign research works and of the long term simulations (2050) of socio-economical systems sparing of carbon (evolution scenarios from emissions abatement policies). The goal is to outline the interesting and useful elements, to shade light and contribute to the debate in France, and to give some guidelines and help and to strengthen the national decisions. Five steps have been considered in this study: the identification of the organizations involved in this research work in the different selected countries, a bibliographic survey of the works carried out by these organizations (Internet search and phone inquiries beside national experts), a collection of the pertinent documents, their analysis, and the elaboration of a synthesis per document with some conclusions. This study is the compilation of all these syntheses made for the five following countries: Germany, Netherlands, United-Kingdom, Switzerland, and Iceland. The scenarios developed by each country are indicative and describe a vision of the society in 2050 with different possible trajectories to reach this situation. They indicate: which goals can be achieved or at least prepared, what can do technologies and what should be the cost of the implementation of these technologies, how to overcome the constraints in order to reach the objectives, and what are the existing margins of freedom given to the political decision. Finally, this analysis shows how the other northern countries deal with the challenge of long term abatement of CO{sub 2} emissions and what solution they propose. (J.S.)

    The need for developing land sparing or land sharing policies for protecting the environment has been a polarized debate in the scientific literature. Some studies show that "spared" landscapes with clearly separated intensive agriculture and pristine forest are better for biodiversity and other...... ecosystem services, whereas others demonstrate the benefits of "shared" mosaic landscapes composed of a mix of forest types, agricultural fields, grassland, and plantations. Increasingly, these scientific views have been depolarized, recognizing that both shared and spared landscapes have a role to play......, depending on the context. However, it is less clear from the literature what drives actual policy-making related to land sparing and land sharing in developing countries and what the outcomes of these policies are. We therefore reviewed the international peer-reviewed literature for evidence of policies...

    Reliability and availability of critical systems play an important role in achieving the stated objectives of engineering assets. Preventive replacement time affects the reliability of the components, thus the number of system failures encountered and its downtime expenses. On the other hand, spare parts inventory level is a very critical factor that affects the availability of the system. Usually, the decision maker has many conflicting objectives that should be considered simultaneously for the selection of the optimal maintenance policy. The purpose of this research was to develop a bi-objective model that will be used to determine the preventive replacement time for three maintenance policies (age, block good as new, block bad as old) with consideration of spare parts’ availability. It was suggested to use a weighted comprehensive criterion method with two objectives, i.e. cost and availability. The model was tested with a typical numerical example. The results of the model demonstrated its effectiveness in enabling the decision maker to select the optimal maintenance policy under different scenarios and taking into account preferences with respect to contradicting objectives such as cost and availability.

  15. Fuel sparing: Control of industrial furnaces using process gas as supplemental fuel

    International Nuclear Information System (INIS)

    Boisvert, Patrick G.; Runstedtler, Allan

    2014-01-01

    Combustible gases from industrial processes can be used to spare purchased fuels such as natural gas and avoid wasteful flaring of the process gases. One of the challenges of incorporating these gases into other furnaces is their intermittent availability. In order to incorporate the gases into a continuously operating furnace, the furnace control system must be carefully designed so that the payload is not affected by the changing fuel. This paper presents a transient computational fluid dynamics (CFD) model of an industrial furnace that supplements natural gas with carbon monoxide during furnace operation. A realistic control system of the furnace is simulated as part of the CFD calculation. The time dependent changes in fuels and air injection on the furnace operation is observed. It is found that there is a trade-off between over-controlling the furnace, which results in too sensitive a response to normal flow oscillations, and under-controlling, which results in a lagged response to the fuel change. - Highlights: •Intermittently available process gases used in a continuously operating furnace. •Study shows a trade-off between over-controlling and under-controlling the furnace. •Over-controlling: response too sensitive to normal flow oscillations. •Under-controlling: lagged response to changing fuel composition. •Normal flow oscillations in furnace would not be apparent in steady-state model

    Purpose/Objective: To determine the relationship between the parotid volume, parotid-planning target volume (PTV) overlap, and dosimetric sparing of the parotid with intensity-modulated radiation therapy (IMRT). Methods and Materials: Parotid data were collected retrospectively for 51 patients treated with simultaneous boost IMRT. Unresectable patients received 54 or 59.4 Gy to subclinical disease, 70 Gy to gross disease. Patients treated postoperatively received 54, 60, and 66 Gy to low-risk, high-risk, and tumor bed regions. Volume and mean dose of each gland and gland segments outside of and overlapping the PTV were collected. Proximity of each gland to each PTV was recorded. Results: Dosimetric sparing (mean dose ≤26.5 Gy) was achieved in 66 of 71 glands with ≤21% parotid-PTV overlap and 8 of 23 glands with >21% overlap (p = 21%. Median mean dose was 25.9 Gy to glands overlapping PTV 54 or PTV 59 alone and 30.0 Gy to those abutting PTV 7 (p 7 was associated with higher parotid dose, satisfactory sparing was achieved in 24 of 43 ipsilateral glands. Conclusions: Dosimetric sparing of the parotid is feasible when the parotid-PTV overlap is less than approximately 20%. With more overlap, sparing may result in low doses within the overlap region, possibly leading to inadequate PTV coverage. Gland proximity to the high-dose PTV is associated with higher mean dose but does not always preclude dosimetric sparing

    The first part of this report covers background of resin bead spectrometry and the new batch resin bead method. In the original technique, about ten anion resin beads in the nitrate form were exposed to the diluted sample solution. The solution was adjusted to be a 8 M HNO 3 and to have about 1 μg U per bead. Up to 48 hours of static contact between beads and solution was required for adsorption of 1 to 3 ng Pu and U per bead to be achieved. Under these conditions, contamination was a problem at reprocessing facilities. The new batch techniques reduces the risk of contamination by handling one hundred times more U in the final diluted sample which is exposed to a proportionately larger number of beads. Moreover, it only requires ten minutes adsorption time to provide about 1000 purified samples for mass spectrometry. The amounts of Pu and U adsorbed versus time were determined and results are tabulated. The second part of this report briefly summarizes results of resin bead field tests completed at the Power Reactor and Nuclear Fuel Development Corporation (PNC) reprocessing plant in Tokai-mura, Japan. Both methods, the original small-sample resin bead and the batch technique, were investigated on spent fuel solutions. Beads were prepared at PNC and distributed to IAEA and ORNL along with dried residues for conventional mass spectrometric analysis at IAEA. Parallel measurements were made at PNC using their normal measuring routines. The U and Pu measurements of all resin and those of PNC are in excellent agreement for the batch method. Discrepancies were noted in the U measurements by the original method

    The Indonesian Family Planning Program was officially launched in 1970 when President Suharto developed the National Family Planning Coordinating Board (BKKBN) to administrate the national family planning program. The inauguration of the family planning program came at the heels of a special demand by the people with very strong support of the ulama. The program was subsequently developed and expanded into remote areas in 1976. In 1992, a family-based approach to family planning was implemented in which every village family was made responsible for family planning. The program is based upon a very strong political commitment at the highest level as well as at the provincial, district, subdistrict, and village levels; it continuously innovates; every community can name its family planning program as it likes; and there is constant feedback to the community. Indonesia's family planning program strategies are as follows: it is suggested that couples in which the wife is aged 20-30 years have only two children; it is recommended that women over age 30 have no more children due to the comparatively high risks of pregnancy at that age; considerable effort is given to encourage youths to not become pregnant and bear children; numerous chairmen of small community family planning groups are appointed; and social and cultural conditions have been created in which people work for family planning activities. People interested in learning from the Indonesian experience in family planning may participate in the BKKBN's international training program.

    SPRINT 4 C is an original system intended for real-time operation on present day computers. It takes into account the specific properties of this kind of process and may be used without any special programming knowledge. Man and machine are continuously interacting since after each statement the system is executing all the computations made possible by the current set of previously introduced definitions. Syntax and semantic errors are detected as soon as they appear. The incorrect statement is eliminated, thus allowing for corrections or improvements. The computation is evolutive, i. e. all the already existing expressions, and/or all those to be defined later, may be used to create new structures. The statements may be read in through the typewriter, the card reader or the paper tape reader attached to the computer, the results being printed on the typewriter or on the line printer. The I/O device connections are possible at any time by means of typed commands. The two modes: 'parameter modification' and 'computation proceeding' allow the user to study the mathematical structure behaviour for different sets of data and then to go on developing the structure by adding new expressions.

    To compare all-cause mortality between women who underwent fertility-sparing surgery with those who underwent conventional surgery for stage I ovarian cancer. In a cohort study using the National Cancer Database, we identified women younger than 40 years diagnosed with stage IA and unilateral IC epithelial ovarian cancer between 2004 and 2012. Fertility-sparing surgery was defined as conservation of one ovary and the uterus. The primary outcome was time from diagnosis to death. We used propensity score methods to assemble a cohort of women who underwent fertility-sparing or conventional surgery but were otherwise similar on observed covariates and conducted survival analyses using the Kaplan-Meier method and Cox proportional hazard models. We identified 1,726 women with stage IA and unilateral IC epithelial ovarian cancer of whom 825 (47.8%) underwent fertility-sparing surgery. Fertility-sparing surgery was associated with younger age, residence in the northeastern and western United States, and serous or mucinous histology (Pfertility-sparing surgery and 37 deaths among propensity-matched women who underwent conventional surgery after a median follow-up of 63 months. Fertility-sparing surgery was not associated with hazard of death (hazard ratio 0.80, 95% confidence interval [CI] 0.49-1.29, P=.36). The probability of survival 10 years after diagnosis was 88.5% (95% CI 82.4-92.6) in the fertility-sparing group and 88.9% (95% CI 84.9-92.0) in the conventional surgery group. In patients with high-risk features such as clear cell histology, grade 3, or stage IC, 10-year survival was 80.5% (95% CI 68.5-88.3) among women who underwent fertility-sparing surgery and 83.4% (95% 76.0-88.7) among those who had conventional surgery (hazard ratio 0.86, 95% CI 0.49-1.53, P=.61). Compared with conventional surgery, fertility-sparing surgery was not associated with increased risk of death in young women with stage I epithelial ovarian cancer.

    Cardiovascular disease (CVD) remains the leading cause of death in the United States today and a major contributor to total health care costs. Psychosocial stress has been implicated in CVD, and psychosocial approaches to primary and secondary prevention are gaining research support. This third article in the series on psychosocial stress and CVD continues the evaluation of one such approach, the Maharishi Transcendental Meditation program, a psychophysiological approach from the Vedic tradition that is systematically taught by qualified teachers throughout the world. Evidence suggests not only that this program can provide benefits in prevention but also that it may reduce CVD-related and other health care expenses. On the basis of data from the studies available to date, the Transcendental Meditation program may be responsible for reductions of 80% or greater in medical insurance claims and payments to physicians. This article evaluates the implications of research on the Transcendental Meditation program for health care policy and for large-scale clinical implementation of the program. The Transcendental Meditation program can be used by individuals of any ethnic or cultural background, and compliance with the practice regimen is generally high. The main steps necessary for wider adoption appear to be: (1) educating health care providers and patients about the nature and expected benefits of the program, and (2) adjustments in public policies at the state and national levels to allow this program to be included in private and public health insurance plans.

    Changes in breast sensation after reconstruction are expected. Return of breast sensation after reconstruction and whether nipple-sparing mastectomy offers a substantial benefit in terms of sensation has been inconsistently documented in the literature. We conducted the current study using the pressure-specified sensory device to quantify postoperative breast sensation in patients undergoing nipple-sparing versus non-nipple-sparing mastectomy. Consecutive adult women who underwent nipple-sparing (NSM) and non-NSM (NNSM) and were at least 18 months postreconstruction were included. Breast measurements were taken in 4 quadrants (upper/lower lateral, upper/lower medial) and nipple. Averaged skin cutaneous thresholds [(UL+LL+UM+LM)/4] and nipple sensation between NSM and NNSM were compared as the primary outcome measure. A generalized estimating equations model was used; univariate and multivariate variable analyses were done when appropriate. Forty-four patients (74 breasts) were examined (53 NNSM vs 21 NSM). The groups were further subdivided into autologous versus implant-based reconstruction. Averaged cutaneous skin thresholds for quadrants were better for the NSM, 51.8(±24.5) g/mm versus NNSM, 56.5(±25.7) g/mm, although this difference was not statistically significant. However, NSM breasts measured higher nipple or nipple area sensitivity, 44.5(±30.8) g/mm versus NNSM, 83.8(±27.4) g/mm (P sensation was the number of revision surgeries, especially after third revision. Breast sensation is decreased after reconstruction in both NSM and NNSM, but nipple sensation or nipple area is better preserved in NSM breasts. Number of revision surgeries (>3) was a predictor of decreased sensation.

    The efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of breast cancer are still questionable. It is estimated that the local recurrence rates following nipple-sparing mastectomy are very similar to breast-conserving surgery followed by radiotherapy. To assess the efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of ductal carcinoma in situ and invasive breast cancer in women. We searched the Cochrane Breast Cancer Group's Specialized Register, the Cochrane Center Register of Controlled Trials (CENTRAL), MEDLINE (via PubMed), Embase (via OVID) and LILACS (via Biblioteca Virtual em Saúde [BVS]) using the search terms "nipple sparing mastectomy" and "areola-sparing mastectomy". Also, we searched the World Health Organization's International Clinical Trials Registry Platform and ClinicalTrials.gov. All searches were conducted on 30th September 2014 and we did not apply any language restrictions. Randomised controlled trials (RCTs) however if there were no RCTs, we expanded our criteria to include non-randomised comparative studies (cohort and case-control studies). Studies evaluated nipple-sparing and areola-sparing mastectomy compared to modified radical mastectomy or skin-sparing mastectomy for the treatment of ductal carcinoma in situ or invasive breast cancer. Two review authors (BS and RR) performed data extraction and resolved disagreements. We performed descriptive analyses and meta-analyses of the data using Review Manager software. We used Cochrane's risk of bias tool to assess studies, and adapted it for non-randomised studies, and we evaluated the quality of the evidence using GRADE criteria. We included 11 cohort studies, evaluating a total of 6502 participants undergoing 7018 procedures: 2529 underwent a nipple-sparing mastectomy (NSM), 818 underwent skin-sparing mastectomy (SSM) and 3671 underwent traditional mastectomy, also known as modified radical

    Purpose: The advent of widespread prostate-specific antigen screening has resulted in more younger, potent men being diagnosed with early-stage, organ-confined prostate cancer amenable to definitive surgery. Nerve-sparing prostatectomy is a relatively new surgical advance in the treatment of prostate cancer. Very few data exist on the effect of postoperative radiotherapy (RT) on erectile function after nerve-sparing prostatectomy. They are based on conventional techniques using moderate doses of radiation, 45-54 Gy. Intensity-modulated RT (IMRT) is becoming more widespread because it allows dose escalation with increased sparing of the surrounding normal tissue. We investigated the effect of postprostatectomy, high-dose IMRT on patients' erectile function. Methods and Materials: A review of patient records found 51 patients treated between April 1998 and December 2000 with IMRT after unilateral or bilateral nerve-sparing prostatectomy. The pathologic disease stage in these patients was T2 in 47.4% and T3 in 52.6%. Postoperatively, 4 patients received hormonal ablation consisting of one injection of Lupron Depot (30 mg) 2 months before RT. The median age was 65 years (range 46-77) at the time of RT. The prescribed dose was 64 Gy (range 60-66). The mean dose was 69.6 Gy (range 64.0-72.3). Erectile function was assessed before and after RT by questionnaires. Sexual potency was defined as erectile rigidity adequate for vaginal penetration. Results: Of the 51 patients, 18 (35.3%) maintained their potency and 33 (64.7%) became impotent after nerve-sparing prostatectomy. Patients who underwent bilateral nerve-sparing prostatectomy had higher rates of postoperative potency than did those who underwent unilateral nerve-sparing surgery (72.2% vs. 27.8%; p=0.025). The follow-up for the entire group was 19.5 months. All 18 patients (100%) who were potent postoperatively remained potent after RT. The median follow-up for the 18 potent patients was 27.2 months, significantly

  19. Impact of shelf life on measured prompt fraction of spare Inconel in-core flux detectors

    Prompt fraction measurements associated with spare self-powered Inconel In-Core Flux Detectors (ICFDs) carried out a few years after installation on Shut Down System number 1 (SDS1) and Reactor Regulating System (RRS) at Darlington Nuclear Generating Station (DNGS), were found to be lower than those of the original detectors. These detectors, spares and originals, were manufactured in the late 80s, however, the former were kept at manufacturer's warehouse and latter were installed in the reactor core within a few years after manufacturing. Although the prompt fractions of the spare detectors were relatively low, the electronic/electrical behavior of the spare detectors was intact. The first batch of the original detectors performed as per the design requirements. Therefore, it is suspected that during shelf life, spare Inconel in-core flux detectors underwent changes that lowered their measured values of prompt fraction, which were taken within a few years after installation in the reactor. Detailed study of detectors' material composition and impurity concentrations revealed no association with the lower prompt fraction measurements. The evaluation of the limited data of the original and spare Inconel ICFDs installed at Darlington showed: 1. The reduction in prompt fraction was roughly proportional to the shelf life of the detectors; and 2. The rate of reduction in prompt fraction during storage was about double the rate of reduction during operation in the reactor. Above observations were based on the data provided by DNGS for a few detectors. The purpose of this paper is two fold, firstly to present the results of the complete study carried out to investigate the cause of relatively low prompt fractions measured on spare SDS1 and RRS Inconel ICFDs at DNGS, and secondly to generate interest/awareness within other CANDU utilities to add to the database of prompt fractions of spare Inconel ICFDs measured after installation. The data will help to improve

    To identify effective aerobic exercise programs and provide clinicians and patients with updated, high-quality recommendations concerning traditional land-based exercises for knee osteoarthritis. A systematic search and adapted selection criteria included comparative controlled trials with strengthening exercise programs for patients with knee osteoarthritis. A panel of experts reached consensus on the recommendations using a Delphi survey. A hierarchical alphabetical grading system (A, B, C+, C, D, D+, or D-) was used, based on statistical significance ( P osteoarthritis within a 12-week period. An aerobic exercise program demonstrated significant improvement for pain relief (Grade B), physical function (Grade B) and quality of life (Grade C+). Aerobic exercise in combination with strengthening exercises showed significant improvement for pain relief (3 Grade A) and physical function (2 Grade A, 2 Grade B). A short-term aerobic exercise program with/without muscle strengthening exercises is promising for reducing pain, improving physical function and quality of life for individuals with knee osteoarthritis.
